Description

Pressure holding device

Technical Field

The invention relates to the technical field of products, and in particular to a pressure maintaining device.

Background Art

When the parts of a product are assembled by bonding, a pressure-maintaining device is usually required to abut and maintain the pressure of the bonded parts until the glue is cured to ensure stable assembly of the product parts.

At present, the pressure-maintaining devices in the related art are basically of the upper and lower pressure-maintaining type, that is, they can only apply pressure-maintaining pressure in one direction to the product. With the continuous development of products, the parts that need to be bonded in some products extend to different sides of the product. For example, the parts of some products have special-shaped curved surface structures, and part of the parts with special-shaped curved surface structures will be bonded to the upper shell of the product, while the other part will extend and bond to the lower shell of the product. At this time, the pressure-maintaining device in the related art can only apply pressure-maintaining pressure in one direction, so it can only abut and maintain pressure on a part of the part with the special-shaped curved surface structure that is bonded to the upper shell of the product, but cannot abut and maintain pressure on the other part that extends to the lower shell of the product, which affects the pressure-maintaining effect of the pressure-maintaining device on this type of product.

It can be seen that the pressure-maintaining device in the present solution is suitable for the use scenarios when the entirety of the bonded parts are located on one side of the product and when the bonded parts extend to different sides of the product because the pressure-maintaining device in the present solution has at least two pressure-maintaining components and the sliding directions of the pressure-maintaining heads in at least two pressure-maintaining components are different, thereby helping to improve the applicability of the pressure-maintaining device in the present solution for maintaining pressure on different types of products.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and/or" appearing in the full text is to include three parallel solutions. Taking "A and/or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

The inventors noticed that the pressure-maintaining device in the related art usually adopts an upper and lower pressure-maintaining method, that is, after the product is placed in the pressure-maintaining device, there is only a pressure-maintaining head that can be raised and lowered to abut and maintain pressure on the product. In other words, the pressure-maintaining direction of this type of pressure-maintaining device is relatively single. However, with the continuous development of products, the parts that need to be bonded on some products will extend to different sides of the product. For example: the parts of some products have a special-shaped curved surface structure, and part of the parts with the special-shaped curved surface structure will be bonded to the upper shell of the product, while the other part will extend and bond to the lower shell of the product. At this time, it is obviously not applicable to use the pressure-maintaining head that only has a liftable pressure-maintaining head in the related art to maintain pressure on the product. It can only abut and maintain pressure on the part of the part that extends to the upper shell of the product through the liftable pressure-maintaining head, but cannot abut and maintain pressure on the part that extends to the lower shell of the product, which affects the pressure-maintaining effect of the pressure-maintaining device on the product.

Therefore, in order to solve the problem that the pressure-maintaining device in the related art cannot meet the pressure-maintaining work of some products due to the single pressure-maintaining direction, the present invention proposes a pressure-maintaining device. In one embodiment of the present invention, please refer to Figures 1 to 6, the pressure-maintaining device 100 includes a product placement seat 10 and at least two pressure-maintaining components 30, the product placement seat 10 is used to place the product to be pressure-maintained; each pressure-maintaining component 30 includes a driving member 31 and a pressure-maintaining head 32, the driving member 31 can drive the pressure-maintaining head 32 to move in the direction close to and away from the product placement seat 10, and the moving directions of the pressure-maintaining heads 32 in at least two pressure-maintaining components 30 are different.

The above-mentioned product placement seat 10 can be used to provide a placement position for placing products to be pressurized (the product can be an earphone shell or other products that need to be pressurized). Among them, the product placement seat 10 can be a plate structure, or a frame structure formed by a combination of multiple plates, etc.; and the projection of the product placement seat 10 on the horizontal plane can be a rectangle, square or circle, etc., and the present application does not limit the specific structure and shape of the product placement seat 10. In order to improve the stability of the product placed on the product placement seat 10, so as to perform accurate and stable pressure maintenance on it later, a product placement groove 11 can be provided on the product placement seat 10, so as to adapt and accommodate the product to be pressurized through the product placement groove 11. The driving member 31 in the pressure-maintaining assembly 30 can be used to provide power, and the pressure-maintaining head 32 can be used to adapt to the product to be pressurized placed on the product placement seat 10. In this way, by applying a holding pressure to the pressure-maintaining head 32 through the driving member 31, and further transmitting the holding pressure to the product to be pressure-maintained by the pressure-maintaining head 32, the pressure-maintaining assembly 30 can be realized to perform pressure-maintaining work on the product to be pressure-maintained. Among them, the driving member 31 can be an elastic member (such as a spring or a plastic member with a certain elasticity, etc.), so as to drive the pressure-maintaining head 32 to be pressed against the product for pressure-maintaining by providing elastic force. Of course, the driving member 31 can also be a cylinder or a linear module, etc., so as to drive the pressure-maintaining head 32 to move against the product for pressure-maintaining. The pressure-maintaining head 32 can be a column structure or a block structure, etc., and has an abutting surface of a shape adapted to the position where the product needs to be abutted for pressure-maintaining, so that it can stably abut against the position where the product needs to be abutted for pressure-maintaining. In addition, the number of the pressure-maintaining assemblies 30 can be two, three or more, and can be specifically adaptively set according to the pressure-maintaining direction required by the product to be pressure-maintained, and this application is not limited to this. The moving directions of the pressure-maintaining heads 32 in at least two pressure-maintaining components 30 are different, which may include the situation that the sliding directions of the pressure-maintaining heads 32 of at least one pressure-maintaining component 30 are at an angle, that is, the pressure-maintaining directions of the at least two pressure-maintaining components 30 to the product are set at an angle. Of course, the moving directions of the pressure-maintaining heads 32 in the at least two pressure-maintaining components 30 are different, which may also include the situation that the sliding directions of the pressure-maintaining heads 32 of at least one pressure-maintaining component 30 are parallel, but they are respectively abutted against the opposite sides of the product to be pressure-maintained, that is, the pressure-maintaining directions of the at least two pressure-maintaining components 30 to the product are set in opposite directions. In addition, it should be noted that the structures of the various pressure-maintaining components 30 in the at least two pressure-maintaining components 30 can be arranged in the same way, or they can be arranged in different ways. In order to make the structure of the pressure-maintaining device 100 relatively simple, pressure-maintaining work can be performed in both the up and down directions and the horizontal directions. The number of the pressure maintaining components 30 can be set to two, and the moving direction of the pressure maintaining head 32 of one of the two pressure maintaining components 30 is parallel to the up-down direction, and the moving direction of the other pressure maintaining head 32 is parallel to the horizontal direction.

When the pressure-maintaining device 100 of the technical solution of the present invention is used, the product to be pressure-maintained can be placed on the product placement seat 10, and then the driving member 31 in the pressure-maintaining component 30 drives the pressure-maintaining head 32 to approach and abut against the product placed on the product placement seat 10, so as to realize the pressure-maintaining work on the product. In addition, since the pressure-maintaining device 100 in this solution includes at least two pressure-maintaining components 30, and the sliding directions of the pressure-maintaining heads 32 in each pressure-maintaining component 30 are different, the pressure-maintaining device 100 in this solution can apply pressure-maintaining forces in different directions. In this way, when the bonded parts extend to different sides of the product, for example, part of the part with a special-shaped curved surface structure is on the upper shell side of the product, and part extends to the lower shell side of the product. At this time, a pressure-maintaining head 32 that slides in the up-down direction can abut against the upper half of the component with the special-shaped curved surface structure, and another pressure-maintaining head 32 that slides in the horizontal direction can abut against the lower half of the component with the special-shaped curved surface structure, so that both the upper and lower parts of the bonded component can be abutted and pressure-maintained. Therefore, the pressure-maintaining device 100 in this solution can abut and maintain pressure on all parts of the bonded component that extend to different sides of the product, thereby improving the pressure-maintaining effect on the product.

Moreover, at least two pressure-maintaining components 30 in the pressure-maintaining device 100 in this solution also include a driving member 31, that is, the driving members 31 in each pressure-maintaining component 30 work independently and do not affect each other. Therefore, the pressure-maintaining forces in different directions of each pressure-maintaining component 30 can be adjusted separately, so as to better carry out targeted abutment and pressure-maintaining on different sides of the product, thereby facilitating further improving the pressure-maintaining effect on the product.

In addition, since at least two pressure-maintaining components 30 in the pressure-maintaining device 100 in the present solution are independently and separately arranged, it can also be used selectively. That is, when the entirety of the bonded parts are located on one side of the product, it can be used only through the pressure-maintaining component 30 corresponding to the side. It can be seen that the pressure-maintaining device 100 in the present solution is suitable for the use scenarios when the entirety of the bonded parts are located on one side of the product and when the bonded parts extend to different sides of the product, which is conducive to improving the applicability of the pressure-maintaining device 100 in the present solution for pressure-maintaining different types of products.

Please refer to Figures 4 and 6 to 8. In one embodiment of the present invention, at least two pressure-maintaining components 30 are defined, including a first pressure-maintaining component 33. The driving member 31 and the pressure-maintaining head 32 in the first pressure-maintaining component 33 are respectively a first driving member 331 and a first pressure-maintaining head 332, and the first driving member 331 is an elastic member. The first pressure-maintaining component 33 also includes a first mounting plate 335. The first pressure-maintaining head 332 is slidably disposed on the first mounting plate 335, and the first driving member 331 is disposed between the first mounting plate 335 and the first pressure-maintaining head 332.

Among them, when the number of pressure-maintaining components 30 is three or more, one pressure-maintaining component 30 can be defined as the first pressure-maintaining component 33, and of course, two or more pressure-maintaining components 30 can be defined as the first pressure-maintaining component 33. When the pressure-maintaining components 30 are configured as described above, one for maintaining pressure in the up and down directions and the other for maintaining pressure in the horizontal direction, the pressure-maintaining component 30 for maintaining pressure in the up and down directions can be formed as the first pressure-maintaining component 33. That is, the first pressure-maintaining head 332 can slide in the up and down directions. In addition, the first driving member 331 is an elastic member, which means that a spring or other elastic element such as a plastic member with a certain elasticity can be used as the first driving member 331, so as to convert the elastic force into the maintaining pressure of the first pressure-maintaining head 332 against the product. The first mounting plate 335 can be used to provide a mounting position for installing the first driving member 331 and the first elastic member.

In this embodiment, the first driving member 331 is set as an elastic member, so that the first pressure-maintaining component 33 is a purely mechanical structure, and no circuits and gas circuits are involved at this time, which is conducive to improving the safety of the use of the first pressure-maintaining component 33 and reducing the convenience of manufacturing the first pressure-maintaining component 33. Moreover, such a setting can also make the volume of the first driving member 331 very small, which is conducive to reducing the overall volume of the first pressure-maintaining component 33 to improve the convenience of its installation in a limited space. In order to further improve the compactness of the structural distribution, the first mounting plate 335 can be set above the product placement seat 10, the first pressure-maintaining head 332 can be set on the side of the first mounting plate 335 facing the product placement seat 10, and the first driving member 331 can be set between the first mounting plate 335 and the first pressure-maintaining head 332.

Further, please refer to Figures 8 and 9. One of the first pressure maintaining head 332 and the first mounting plate 335 is provided with a first sleeve 333, and the other one is provided with a first insertion rod 336; the first sleeve 333 is extended along the sliding direction of the first pressure maintaining head 332, and the first insertion rod 336 is slidably inserted in the first sleeve 333, and the first driving member 331 is sleeved on the outside of the first sleeve 333 and the first insertion rod 336.

The first sleeve 333 and the first insertion rod 336 form a telescopic mechanism, so that the first insertion rod 336 and the first sleeve 333 can slide relative to each other, but the two will not slide apart.

In this embodiment, the first sleeve 333 and the first plug rod 336 are inserted and matched, so that the sliding connection between the first pressure-maintaining head 332 and the first mounting plate 335 can be realized. At the same time, the cooperation between the first sleeve 333 and the first plug rod 336 also has a guiding function, so as to ensure that the first pressure-maintaining head 332 slides accurately and stably, and the product can be more accurately abutted and pressure-maintained. In addition, the cooperation between the first sleeve 333 and the first plug rod 336 can also be used to provide an installation position, so that the first driving member 331 formed by the elastic member can be directly sleeved and installed on the outside of the first sleeve 333 and the first plug rod 336, so as to realize the rapid installation of the first driving member 331, and subsequently, the elastic force direction of the first driving member 331 can also be guided and limited, so as to further ensure that the first pressure-maintaining head 332 can accurately abut and pressure-maintain on the product. It can be seen that at this time, the first sleeve 333 and the first plug rod 336 are set in combination. Through this simple structure, the sliding installation of the first pressure-maintaining head 332, the sliding guidance of the first pressure-maintaining head 332, the rapid installation of the first driving member 331, and the limiting guiding function can be achieved at the same time, which is conducive to greatly simplifying the structure of the pressure-maintaining device 100 and reducing the manufacturing cost of the pressure-maintaining device 100. At the same time, it is also conducive to improving the accuracy and stability of the device in maintaining the pressure of the product. Further, in order to facilitate the replacement of the first driving member 331 to adjust the pressure of the first pressure-maintaining component 33. The first sleeve 333 and the first plug rod 336 can be detachably connected. Specifically, the first sleeve 333 can be connected by screws or fixed by clamping, and the first plug rod 336 can also be connected by screws or fixed by clamping. In addition, it should be noted that the present application is not limited to this. In other embodiments, the first pressure maintaining head 332 and the first mounting plate 335 can also be slidably connected through a combination of a slider and a slide groove, and the first driving member 331 can also be directly welded to the first mounting plate 335 and the first pressure maintaining head 332 through its opposite ends.

Please refer to FIG. 4 and FIG. 6 , in one embodiment of the present invention, the first mounting plate 335 is detachably connected to the product placement seat 10 .

The first mounting plate 335 is detachably connected, that is, the first mounting plate 335 can be connected to the product placement seat 10 to form an integral structure, and the first mounting plate 335 can also be removed from the product placement seat 10. The first mounting plate 335 can be fixed to the product placement seat 10 by snap connection, or by magnetic attraction.

In this embodiment, the first mounting plate 335 is detachably connected, so that when the pressure-maintaining device 100 is used, the first mounting plate 335 can be firstly removed from the product placement seat 10. At this time, that is, the first pressure-maintaining component 33 is removed from the product placement seat 10, so that the product placement seat 10 can be directly exposed better, so that it is convenient for the operator to easily place the product on the product placement seat 10, or remove the product that has completed the pressure-maintaining work from the product placement seat 10.

Further, please refer to Figures 6, 7 and 9. The first mounting plate 335 is provided with a rotatable first clamping member 337. The first clamping member 337 has a first hook 338 at one end close to the product placement seat 10. A first elastomer 339 is provided between the end of the first clamping member 337 away from the first hook 338 and the first mounting plate 335. The first elastomer 339 can drive the first hook 338 to be clamped on the product placement seat 10.

When the first pressure-maintaining head 332 is slidably arranged in the up-down direction, the first clamping member 337 can be a plate structure extending in the up-down direction. The first elastic body 339 can be arranged between the upper end of the first clamping member 337 and the first mounting plate 335 to provide elastic force to drive the upper end of the first clamping member 337 to rotate away from the first mounting plate 335, so that the lower end of the first clamping member 337 provided with the first hook 338 rotates in the direction close to the product placement seat 10 and is clamped to the product placement seat 10. When the first mounting plate 335 needs to be disassembled, the upper end of the first clamping member can be directly pressed so that the first hook 338 at the lower end of the first clamping member 337 is disengaged from the product placement seat 10 to achieve unlocking. Among them, the first elastic body 339 can be a spring or other elastic elements such as a plastic part with a certain elasticity.

In this embodiment, the first mounting plate 335 is fixed by the first clamping member 337, so that the connection between the first mounting plate 335 and the product placement seat 10 can be simplified to improve the convenience of disassembly and assembly. The first clamping member 337 is rotatable, so that when the first mounting plate 335 is disassembled and unlocked, only one end of the first clamping member 337 needs to be pressed very simply, and no shaking effect will be generated. Therefore, the first clamping member 337 is rotatable, which further improves the convenience of disassembly and assembly of the first mounting plate 335, and also improves the stability of the pressure-maintaining device 100 during the disassembly process. The setting of the first elastic body 339 can make the first clamping member 337 stably clamped to the product placement seat 10, and can also provide an elastic force to realize the automatic reset of the first clamping member 337 after being abutted and pressed. In order to improve the stability of the clamping connection between the first mounting plate 335 and the product placement seat 10, while ensuring that the structure of the pressure maintaining device 100 is not too complicated, the number of first clamping parts 337 can be set to be , and they are respectively located on the opposite sides of the first mounting plate 335, so as to achieve locking force between the first mounting plate 335 and the product placement seat 10 on both opposite sides.

Further, please refer to Figures 8 to 10. The product placement seat 10 is provided with a clamping groove 12 for the first clamping hook 338 to clamp, and the clamping groove 12 has two groove walls arranged opposite to each other in the sliding direction of the first pressure maintaining head 332; the first clamping hook 338 is clamped to the groove wall arranged near the first mounting plate 335 among the two opposite groove walls of the clamping groove 12, and is spaced apart from the other groove wall of the two opposite groove walls of the clamping groove 12; a slidable limit plate 340 is provided on the side of the first mounting plate 335 facing the product placement seat 10, and the sliding direction of the limit plate 340 is parallel to the sliding direction of the first pressure maintaining head 332, and an elastic element 342 is provided between the limit plate 340 and the first mounting plate 335, and the side of the limit plate 340 facing away from the first mounting plate 335 is used to abut against the product placement seat 10.

When the first pressure-maintaining head 332 is slidably arranged in the up-down direction, the engaging groove 12 has two groove walls arranged opposite to each other in the sliding direction of the first pressure-maintaining head 332, that is, the side wall of the product placement seat 10 may be recessed to form the engaging groove 12, and the engaging groove 12 forms two groove walls arranged opposite to each other in the up-down direction. At this time, the first hook 338 may be engaged with the upper groove wall of the engaging groove 12, and may be spaced apart from the lower groove wall to have a gap. The limiting plate 340 arranged on the side of the first mounting plate 335 facing the product placement seat 10 may be used to abut against the product placement seat 10 to prevent the first mounting plate 335 from being suspended and falling due to the gap between the first hook 338 and the lower groove wall of the engaging groove 12. Furthermore, the limit plate 340 can be slidably arranged, and an elastic element 342 composed of a spring or other elastic plastic parts is arranged between the limit plate 340 and the product placement seat 10, so that the limit plate 340 and the product placement seat 10 can be buffered when abutting against each other without causing a large collision impact on the product.

In this embodiment, since there is a gap between the first hook 338 and the lower groove wall in the clamping groove 12, the first hook 338 will not interfere with the lower groove wall of the clamping groove 12 during the rotation process, which is conducive to improving the smoothness of the rotation of the first clamping member and improving the service life of the first clamping member 337. At the same time, through the abutment between the limiting plate 340 and the product placement seat 10, the abutment support of the product placement seat 10 on the first pressure-maintaining component 33 is realized, so that the first mounting plate 335 will not fall, and the stable and effective clamping of the first clamping member 337 and the upper groove wall of the product clamping groove 12 is ensured. In addition, since an elastic element 342 is provided between the limiting plate 340 and the first mounting plate 335, and the limiting plate 340 is slidable, when the first pressure-maintaining component 33 is assembled on the product placement seat 10, the limiting plate 340 and the product placement seat 10 can be buffered and protected when they are abutted, which is conducive to reducing the possibility of the first pressure-maintaining component 33 being damaged by a large impact when it is assembled on the product placement seat 10. The limiting plate 340 and the first pressure-maintaining head 332 can be arranged on the lower surface of the first mounting plate 335 and arranged at intervals to improve the compactness of the distribution between the various components in the first pressure-maintaining assembly 33. In addition, in order to simplify the installation between the limiting plate 340, the elastic element 342 and the first mounting plate 335. Please refer to Figures 8 and 10, the limiting plate 340 can be provided with one of the sleeve 341 and the slide bar 343, the first mounting plate 335 can be provided with the other of the sleeve 341 and the slide bar 343, the sleeve 341 extends along the sliding direction of the limiting plate 340, the slide bar 343 can be slidably inserted in the sleeve, and the elastic element 342 can be sleeved on the outer side of the sleeve 341 and the slide bar 343. Further, in order to facilitate the setting of the clamping groove 12 and save the manufacturing materials of the product placement seat 10 to reduce the manufacturing cost, in one embodiment, the product placement seat 10 may include a bottom plate 15, a side plate 16, a first seat body 17 and a second seat body 19. Among them, the side plate 16 can be set on one side of the bottom plate 15 and extend upward, and the outer side of the side plate 16 can be provided with a clamping groove 12. The first seat body 17 and the second seat body 19 can be arranged on the bottom plate 15 at intervals, and the first seat body 17 can be provided with a product placement groove 11 for placing the product to be pressure-maintained, and the second seat body 19 can be used to abut against the support limit block. At this time, the first mounting plate 335 of the first pressure-maintaining component 33 can be arranged above the side plate 16 of the product placement seat 10, and can be clamped and fixed with the clamping groove 12 on the side plate 16 through the first clamping member 337. The first pressure-maintaining head 332 in the first pressure-maintaining component 33 can be arranged above the first seat body 17, and the limit block can be arranged above the second seat body 19. In addition, in order to ensure that the first pressure-maintaining component 33 can be accurately assembled onto the product placement seat 10 to perform pressure-maintaining work, the first pressure-maintaining head 332 can also be provided with a positioning rod 334, and the first seat body 17 can be correspondingly provided with a positioning hole 18 for inserting the positioning rod 334, so as to ensure the accurate matching and pressure maintenance of the first pressure-maintaining head 332 and the first seat body 17 through the plug-in positioning of the positioning rod 334 and the positioning hole 18.

Please refer to Figures 1 to 4 and Figure 6. In one embodiment of the present invention, the pressure maintaining device 100 also includes a first unlocking component 50, which can drive the first hook 338 and the product placement seat 10 to disengage, and can drive the first mounting plate 335 to slide along a sliding direction parallel to the first pressure maintaining head 332.

In this embodiment, the first unlocking assembly 50 is provided to disassemble and remove the first pressure-maintaining assembly 33, so that there is no need to manually unlock the first pressure-maintaining assembly 33. This improves the automation level of the pressure-maintaining device 100, thereby further improving the convenience of using the pressure-maintaining device 100. Of course, when the first unlocking assembly 50 is not provided, the first clamping member 337 can be directly pressed manually to unlock and disassemble.

Further, please refer to Figures 1 to 4, 6 and 9. The surface of the first mounting plate 335 parallel to the sliding direction of the first pressure maintaining head 332 is provided with a mounting groove 345, and the first clamping member 337 is rotatably disposed in the mounting groove 345; the first unlocking component 50 includes a first driving member 51, a second driving member 53 and a first pressing member 55, the second driving member 53 is disposed on the first driving member 51, and the first pressing member 55 is disposed on the second driving member 53; the first driving member 51 can drive the second driving member 53 and the first pressing member 55 to slide along a sliding direction parallel to the first pressure maintaining head 332, and the first pressing member 55 can be driven by the second driving member 53 to abut and press one end of the first clamping member 337 away from the first hook 338.

The first mounting plate 335 is provided with a mounting groove 345 on a surface parallel to the sliding direction of the first pressure-maintaining head 332. That is to say, when the first pressure-maintaining head 332 is slidably arranged in the up-down direction, the side wall surface of the first mounting plate 335 is provided with a mounting groove 345, and the mounting groove 345 penetrates the lower surface of the first mounting plate 335. At this time, the first clamping member 337 can be accommodated by the mounting groove 345. The first driving member 51 and the second driving member 53 of the first unlocking component 50 can both be used to provide power to drive the first pressing member 55 to move up and down and horizontally, respectively. Specifically, the first driving member 51 can drive the second driving member 53 and the first pressing member 55 to descend to a preset height, so that the upper ends of the first pressing member 55 and the first clamping member 337 are located at the same height. Then, the second driving member 53 drives the first pressing member 55 to contract, and the first pressing member 55 can be used to abut and press the upper end of the first clamping member 337, so as to press and unlock the first clamping member 337. At this time, the first pressing member 55 can be inserted into the mounting groove 345 after abutting and pressing the first clamping member 337. Therefore, when the first driving member 51 drives the second driving member 53 and the first pressing member 55 to rise and reset, the first mounting plate 335 can be driven to rise and realize the separation of the first pressure-maintaining component 33 and the product placement seat 10, so as to facilitate the subsequent removal of the product from the product placement seat 10, or the placement of the product on the product placement seat 10. When the first pressure-maintaining component 33 needs to be assembled on the product placement seat 10 again, the first driving member 51 can drive the second driving member 53 and the first pressing member 55 to descend to a preset height again, so that the first pressure-maintaining component 33 is placed on the upper end of the product placement seat 10. Then, the first pressing member 55 is extended by the second driving member 53, so that the first pressing member 55 no longer presses the first clamping member 337. At this time, the first pressing member 55 can be driven to rotate and reset under the elastic force of the first elastic body 339, so that the first hook 338 on the first clamping member 337 is clamped in the clamping groove 12 on the product placement seat 10. The first driving member 51 and the second driving member can both be cylinders or linear motors, and the first pressing member 55 can be a plate structure or a column structure. In addition, in order to ensure that the first unlocking component 50 can stably drive the first pressure maintaining component 33 to slide in a direction parallel to the first pressure maintaining head 332, the number of first clamping parts 337 can be set to two, and they are respectively located on the opposite sides of the first mounting plate 335; and the number of second driving members 53 and first pressing members 55 can also be set to two, so that a first clamping member 337 can be correspondingly abutted and pressed by a second driving member 53 and a first pressing member 55, and then can be inserted into the mounting grooves 345 for installing the first clamping member 337 on the opposite sides of the first mounting plate 335, so as to achieve stable clamping and fixation of the opposite sides of the first mounting plate 335. Of course, the number of the first clamping member 337, the second driving member 53 and the first pressing member 55 can all be set to one. In this case, an abutment structure abutting against the side of the first mounting plate 335 away from the first clamping member 337 can be set on the second driving member 53, the product placement seat 10 or other positions, so as to block the first mounting plate 335 from moving along the pressing direction of the first pressing member 55 when the first pressing member 55 abuts and presses the first clamping member 337.

In this embodiment, the first clamping member 337 is accommodated by providing a mounting groove 345, so that the pressing member can be inserted into the mounting groove 345 after abutting and pressing the first clamping member 337. In this way, the plug-in connection between the first mounting plate 335 and the first pressing member 55 is realized, so that it is convenient to drive the first pressure-maintaining assembly 33 to slide when the first driving member 51 drives the first driving member 51 to slide. At the same time, the provision of the mounting groove 345 can also make the first clamping member 337 more compactly installed, which is conducive to further reducing the overall volume of the first pressure-maintaining assembly 33. The first unlocking assembly 50 is provided with the first driving member 51, the second driving member 53 and the first pressing member 55, so that the first clamping member 337 on the first mounting plate 335 is not only unlocked by pressing through the second driving member 53 and the first pressing member 55, but also the connection relationship with the first mounting plate 335 is established. At this point, it can be said that the first unlocking component 50 realizes several functions through one structure, which is conducive to greatly simplifying the structure of the first unlocking component 50, so as to improve the convenience of its manufacture and reduce the manufacturing cost. Among them, in order to make the various mechanisms in the pressure-maintaining device 100 be distributed more regularly, the first unlocking component 50 can be arranged above the product placement seat 10. In addition, in order to facilitate the installation and fixation of the first unlocking component 50, the guarantee device can also include a frame 70, the first driving member 51 in the first unlocking component 50 can be connected to the frame 70, and the product placement seat 10 can be placed on the frame 70. In addition, it should be noted that in other embodiments, the first unlocking component 50 can also be directly a manipulator, which can grab the first mounting plate 335 and abut and press the first clamping member 337.

Please refer to Figures 6, 11 and 12. In one embodiment of the present invention, at least two pressure-maintaining components 30 are defined to include a second pressure-maintaining component 35. The driving member 31 and the pressure-maintaining head 32 in the second pressure-maintaining component 35 are respectively a second driving member 351 and a second pressure-maintaining head 352, and the second driving member 351 is an elastic member. The second pressure-maintaining component 35 also includes a second mounting plate 354. The second pressure-maintaining head 352 is slidably disposed on the second mounting plate 354, and the second driving member 351 is disposed between the second mounting plate 354 and the second pressure-maintaining head 352.

Among them, when the number of pressure-maintaining components 30 is three or more, one pressure-maintaining component 30 can be defined as the second pressure-maintaining component 35, and of course, two or more pressure-maintaining components 30 can be defined as the first pressure-maintaining component 33. When the pressure-maintaining components 30 are configured as described above, one for maintaining pressure in the up and down directions and the other for maintaining pressure in the horizontal direction, the pressure-maintaining component 30 for maintaining pressure in the horizontal direction can be formed into the second pressure-maintaining component 35. That is, the second pressure-maintaining head 352 can slide in the horizontal direction. In addition, the second driving member 351 is an elastic member, which means that a spring or other elastic element such as a plastic member with a certain elasticity can be used as the second driving member 351, so as to convert the elastic force into the maintaining pressure of the second pressure-maintaining head 352 against the product. The second mounting plate 354 can be used to provide a mounting position for installing the second driving member 351 and the second elastic member.

In this embodiment, the second driving member 351 is set as an elastic member, which can also make the second pressure-maintaining assembly 35 a purely mechanical structure, and will not involve circuits and gas circuits, etc., which is conducive to improving the safety of the use of the second pressure-maintaining assembly 35 and reducing the convenience of manufacturing the second pressure-maintaining assembly 35. Moreover, such a setting can also make the volume of the second driving member 351 very small, which is conducive to reducing the overall volume of the second pressure-maintaining assembly 35, so as to improve the convenience of installation in a limited space.

Further, please refer to Figures 12 and 13. One of the second pressure maintaining head 352 and the second mounting plate 354 is provided with a second sleeve 353, and the other one is provided with a second insertion rod 355; the second sleeve 353 is extended along the sliding direction of the second pressure maintaining head 352, and the second insertion rod 355 is slidably inserted in the second sleeve 353, and the second driving member 351 is sleeved on the outside of the second sleeve 353 and the second insertion rod 355.

The second sleeve 353 and the second insertion rod 355 also form a telescopic mechanism, so that the second insertion rod 355 and the second sleeve 353 can slide relative to each other, but the two will not slide apart.

In this embodiment, the second sleeve 353 and the second plug rod 355 are inserted and matched, so that the sliding connection between the second pressure-maintaining head 352 and the second mounting plate 354 can be realized. At the same time, the cooperation between the second sleeve 353 and the second plug rod 355 also has a guiding function, so as to ensure that the second pressure-maintaining head 352 slides accurately and stably, and the product can be more accurately abutted and pressure-maintained. In addition, the cooperation between the second sleeve 353 and the second plug rod 355 can also be used to provide an installation position, so that the second driving member 351 formed by the elastic member can be directly sleeved and installed on the outside of the second sleeve 353 and the second plug rod 355, so as to realize the rapid installation of the second driving member 351, and subsequently, the elastic force direction of the second driving member 351 can also be guided and limited, so as to further ensure that the second pressure-maintaining head 352 can accurately abut and pressure-maintain on the product. It can be seen that the second sleeve 353 and the second plug rod 355 are combined at this time. Through this simple structure, the sliding installation of the second pressure-maintaining head 352, the sliding guidance of the second pressure-maintaining head 352, the rapid installation of the second driving member 351, and the limiting guiding function can be achieved at the same time, which is conducive to greatly simplifying the structure of the pressure-maintaining device 100 and reducing the manufacturing cost of the pressure-maintaining device 100. At the same time, it is also conducive to improving the accuracy and stability of the device in maintaining the pressure of the product. Further, in order to facilitate the replacement of the second driving member 351 to adjust the pressure of the second pressure-maintaining component 35. The second sleeve 353 and the second plug rod 355 can be detachably connected. Specifically, the second sleeve 353 can be connected or fixed by a clamp, and the second plug rod 355 can also be connected or fixed by a screw. In addition, it should be noted that the present application is not limited to this. In other embodiments, the second pressure maintaining head 352 and the second mounting plate 354 can also be slidably connected through a combination of a slider and a slide groove, and the second driving member 351 can also be directly welded to the second mounting plate 354 and the second pressure maintaining head 352 through its opposite ends.

Further, please refer to Figure 12, the second mounting plate 354 can be slidably disposed on the product placement seat 10, and the sliding direction of the second mounting plate 354 is parallel to the sliding direction of the second pressure maintaining head 352; when the second mounting plate 354 slides until the second pressure maintaining head 352 abuts against the product to be pressure maintained placed on the product placement seat 10, the second mounting plate 354 can be limited and fixed relative to the product placement seat 10.

The second mounting plate 354 can be fixed in a limited position relative to the product placement seat 10, which means that when the second mounting plate 354 is close to a preset distance from the first seat body in the product placement seat 10 for placing the product to be pressurized, the second mounting plate 354 can be limitedly connected to the product placement seat 10 without continuing to slide, so that the second pressure-maintaining head 352 can be stably in a position to perform stable abutment and pressure-maintaining work on the product.

In this embodiment, the second mounting plate 354 is set to be slidable, so that the second pressure-maintaining head 352 can be moved away from the product placement seat 10 by driving the second mounting plate 354 away from the product placement seat 10, so that the operator can easily place the product on the product placement seat 10, or remove the product that has completed the pressure-maintaining work from the product placement seat 10. The second mounting plate 354 is slidably set on the product placement seat 10, so that the second pressure-maintaining component 35 and the product placement seat 10 are connected, and only the first pressure-maintaining component 33 can be disassembled and separated from the product placement seat 10. In this way, the pressure-maintaining device 100 can be said to have only two detachable mechanisms, and the number is not too large, which is conducive to simplifying the structure of the pressure-maintaining device 100 to improve the convenience of assembling it when in use. In order to simplify the sliding installation structure of the second mounting plate 354 and ensure the stable sliding of the second mounting plate 354, a guide rod 20 can be set on the second seat body 19 of the product placement seat 10. The guide rod 20 can be extended along the sliding direction of the second mounting plate 354, and the second mounting plate 354 can be slidably mounted on the guide rod 20.

Furthermore, the product placement seat 10 is provided with a rotatable second clamping member 13, and a second hook 14 is provided at one end of the second clamping member 13 close to the second mounting plate 354; a second elastomer 131 is provided between the end of the second clamping member 13 away from the second hook 14 and the product placement seat 10. When the second mounting plate 354 slides until the second pressure maintaining head 352 abuts against the product to be pressure maintained placed on the product placement seat 10, the second elastomer 131 can drive the second hook 14 to be clamped to the second mounting plate 354.

The second pressure-maintaining head 352 can be slidably arranged in the horizontal direction, and the second clamping member 13 can be a plate structure extending in the horizontal direction, and can be arranged on the second seat 19 of the product placement seat 10, so that the second pressure-maintaining module can be located between the bottom plate 15 of the product placement seat 10 and the first pressure-maintaining module, further improving the compactness of the structure of the pressure-maintaining device 100. The second elastic body 131 can be arranged between one end of the second clamping member 13 away from the second pressure-maintaining head 352 and the second seat 19, so as to provide elastic force to drive the other end of the second clamping member 13 to be clamped on the side of the second mounting plate 354 away from the second seat 19 after the second mounting plate 354 slides into place. When the second mounting plate 354 needs to be unlocked, the second clamping member 13 can be directly pressed on the end away from the second hook 14, so that the second hook 14 of the second clamping member 13 and the second mounting plate 354 are separated to achieve unlocking. Among them, the second elastic body 131 can be a spring or other elastic elements such as a plastic part with a certain elasticity.

In this embodiment, the second mounting plate 354 is fixed by the second clamping member 13, which can simplify the limiting structure of the second mounting plate 354 and improve the convenience of unlocking it. The second clamping member 13 is rotatable, so that when the second mounting plate 354 is limited and unlocked, it is only necessary to perform a very simple pressing operation on one end of the second clamping member 13, and no shaking effect will be generated. Therefore, the second clamping member 13 is rotatable, which further improves the convenience of unlocking the second mounting plate 354, and also improves the stability of the pressure-maintaining device 100 during the unlocking process. The setting of the second elastic body 131 can make the second clamping member 13 stably clamped to the second plate body, and can also provide an elastic force to realize the automatic reset of the second clamping member 13 after being abutted and pressed.

Further, please refer to Figures 1 to 5 and Figure 12. The pressure maintaining device 100 also includes a second unlocking component 90, which can drive the second hook 14 and the second mounting plate 354 to disengage, and can drive the second mounting plate 354 to slide along a sliding direction parallel to the second pressure maintaining head 352.

In this embodiment, the second unlocking assembly 90 is provided to limit and unlock the second pressure-maintaining assembly 35, so that there is no need to manually unlock the second pressure-maintaining assembly 35. This further improves the automation of the pressure-maintaining device 100, thereby further improving the convenience of using the pressure-maintaining device 100. Of course, when the second unlocking assembly 90 is not provided, the second clamping member 13 can be directly pressed manually to unlock.

Further, please refer to Figures 1 to 5 and 12. The second unlocking component 90 includes a third driving member 91, a second pressing member 93 and a third elastic body 95. The second pressing member 93 is arranged on the third driving member 91, and can be driven by the third driving member 91 to abut and press the end of the second clamping member 13 away from the second hook 14; the third elastic body 95 is arranged between the product placement seat 10 and the second mounting plate 354, and can drive the second mounting plate 354 to slide in a direction away from the product placement seat 10.

The third driving member 91 can be used to provide power to drive the second pressing member 93 to approach or move away from the second clamping member 13. The third elastic body 95 can be used to provide elastic force, that is, when the second mounting plate 354 slides in the direction close to the first seat body 17 for placing the product to be pressure-maintained in the product placement seat 10 to engage with the second hook 14 of the second clamping member 13, the third elastic body 95 is compressed to generate deformation elastic force. Afterwards, after the second clamping member 13 is abutted and pressed and unlocked by the second pressing member 93, the second mounting plate 354 can be reset under the deformation elastic force of the third elastic body 95, and drive the second pressure-maintaining head 352 connected to the second mounting plate 354 to move away from the first seat body 17, so as to place the product on the first seat body 17, or take the product out of the first seat body 17. Then, when it is necessary to maintain pressure again through the second pressure-maintaining head 352, the second mounting plate 354 can be driven to slide again to engage with the second clamping member 13.

In this embodiment, the second unlocking assembly 90 is configured as a third driving member 91, a second pressing member 93 and a third elastic body 95, so that the third driving member 91 and the second pressing member 93 can conveniently realize the abutment and pressing of the second clamping member 13; and the third elastic body 95 can simplify the driving structure of the second mounting plate 354 and reduce the manufacturing cost on the basis of ensuring that the second mounting plate 354 can be driven. Moreover, it is particularly important that, since the volume of the third elastic body 95 is very small, the convenience of its installation and setting can be greatly improved in a limited space. Among them, the third driving member 91 can be a cylinder or a linear motor, etc., and the second pressing member 93 can be a plate structure or a column structure, etc. In order to further improve the compactness of each mechanism of the pressure-maintaining device 100, the third driving member 91 can also be arranged on the frame 70 and located on one side of the product placement seat 10 in the horizontal direction, and the third elastic body 95 can be directly sleeved on the guide rod 20 for the second plate body to be slidably installed. In addition, the second unlocking component 90 can also include a fourth driving member 97 and a pushing rod 99. The fourth driving member 97 can be set on the frame 70, and the pushing rod 99 can be connected to the fourth driving member 97, so as to drive the pushing rod 99 to abut and drive the second mounting plate 354 to slide along the direction of the first seat body 17 for placing the product to be pressurized in the product placement seat 10. In this way, the operation of driving the second pressure maintaining head 352 of the second pressure maintaining component 35 to abut and pressurize the product to be pressurized does not need to be manually completed by the operator, which is conducive to further improving the convenience of using the pressure maintaining device 100.

In one embodiment of the present invention, the specific use process of the pressure-maintaining device 100 in the present invention can be: first, the pressure-maintaining module composed of the product placement seat 10, the first pressure-maintaining component 33 and the second pressure-maintaining component 35 is placed on the frame 70; then, the first driving member 51 in the first unlocking component 50 can drive the second driving member 53 and the second pressing member 93 to descend to a preset height, so that the first pressing member 55 can be driven to contract by the second driving member 53 to abut against and press the first clamping member 337, thereby unlocking the first mounting plate 335 and clamping the first mounting plate 335; further, the first driving member 51 can drive the second driving member 53 to reset, thereby completing the opening of the first pressure-maintaining component 33.
