Technical Field

The invention relates to the technical field of photovoltaic modules, in particular to corner protection tape sticking equipment for a photovoltaic module lamination process.

Background

The battery piece stacks in double glazing, and the whole evacuation of air forms the vacuum, protects the battery piece not influenced by external environment, improves photovoltaic module's life. The corner protectors are arranged at four corner positions of the photovoltaic module, so that the glue overflow amount between two layers of glass in the lamination process can be limited, and the aim of limiting the lamination thickness of the module is fulfilled.

The Chinese patent publication No. CN116190493A discloses an automatic assembly device of the corner protector for the lamination process of the photovoltaic module, which can realize the synchronous placement of the corner protector around the photovoltaic module and the fixation of the corner protector at four corners of the photovoltaic module by attaching adhesive tapes. The corner protection process corresponding to the device disclosed in the patent document is as follows: the method comprises the steps that adhesive tapes are respectively attached to two protective arms of the protective angle, the adhesive tapes are cut after lamination, the protective angle is pulled out backwards, the periphery of the existing photovoltaic module corresponding to the protective angle installation process comprises two long-side and short-side adhesive tapes before the protective angle installation, two groups of attaching devices are required to be arranged at each corner of the photovoltaic module corresponding to equipment, and eight groups of attaching devices are required to be arranged in one piece of equipment. In addition, in the corner protector mounting process of the technical scheme, in order to facilitate subsequent disassembly of the corner protector, a groove is required to be formed in the outer side faces of the two corner protector arms of the corner protector so as to facilitate subsequent cutting of the adhesive tape, on one hand, the corner protector with the groove is required to be customized, on the other hand, the cut adhesive tape is likely to remain on the photovoltaic module, and later cleaning is required, so that the cost and the procedure are increased. Moreover, the equipment cannot be suitable for mounting the corner protector of the existing photovoltaic module, wherein side tapes are not attached to the periphery of the corner protector before mounting. Accordingly, there is a need for a new corner bead taping apparatus for use in a photovoltaic module lamination process for installation of existing corner beads of photovoltaic modules that are not taped prior to corner bead installation.

It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.

Example 1

The corner protection tape sticking device for the lamination process of the photovoltaic module provided in this embodiment, referring to fig. 1 to 19, mainly includes a first transmission module 10, four corner protection tape sticking modules 20, four side tape sticking modules 40 and a feeding module 30.

The first transmission module 10 extends along the front-back direction shown in fig. 1 to perform conveying of the photovoltaic module 50 (it should be noted that, here, the front-back direction is not the front direction and the back direction shown in fig. 1, but the side of the device facing the reader is the front side and the side facing away from the reader is the back side), so as to facilitate inputting and outputting of the photovoltaic module 50, and the first transmission module 10 is used for conveying the photovoltaic module 50 (including inputting of the photovoltaic module 50 to be laminated and outputting of the laminated photovoltaic module 50) and positioning when placing the corner protector 60 and the tape. The structure and the working principle of the first transmission module 10 are not described, and the conventional transmission module for the photovoltaic module 50 is not an innovation point of the present invention in the prior art, and is easily known and implemented by those skilled in the art. For convenience of description and distinction, in this embodiment, the conveying direction of the first conveying module 10 is described as a first direction, and the left-right direction as shown in fig. 1 is described as a second direction, where the first direction and the second direction are perpendicular in the same horizontal plane, the vertical direction is perpendicular to the first direction and the second direction in space, and the first direction, the second direction and the vertical direction are perpendicular to each other in space, so as to form a triaxial direction of the triangular coordinate system. The corner protector 60 is not described or limited in its structure, and is described with reference to the prior art descriptions in the background section, and is not an innovation of the present invention.

The four corner protection tape attaching modules 20 in the embodiment are respectively disposed at the outer sides of the four corners of the first transmission module 10 and can respectively move towards or away from the corresponding corners of the to-be-laminated photovoltaic module 50 on the middle first transmission module 10 to complete the installation and fixation of the corner protection 60 and the attachment and fixation of the first tape 70. Compared with the prior art in the background art, the installation and sticky tape fixation of the corner protector 60 can be completed by only one module for each corner protector 60, the structure is fewer, the cost is lower, and the subsequent sticky tape disassembly is simpler. Specifically, as shown in fig. 4, 8, 9 and 19, each corner bead taping module 20 mainly includes a fixed-length adhesive tape breaking assembly 21, a corner bead placement positioning mechanism 22 and an adhesive tape attaching mechanism 23. As shown in fig. 9, the fixed-length broken tape assembly 21, the corner protection positioning mechanism 22 and the tape attaching mechanism 23 are mounted on the same base (not shown) and are driven to move toward or away from the corner of the photovoltaic module 50 corresponding to the corner protection tape assembly 20, the corner protection positioning mechanism 22 is closer to the photovoltaic module 50, the corner protection positioning mechanism 22 first contacts the photovoltaic module 50 and presses the corner protection 60 fixed thereon against the corner of the photovoltaic module 50 when approaching, and then the tape attaching mechanism 23 moves toward the corner approaching or away from the photovoltaic module 50 along the diagonal direction of the base or the diagonal direction of the corner protection 60 relative to the fixed-length broken tape assembly 21 and the corner protection positioning mechanism 22 so as to fix the corner protection 60 to the corner of the photovoltaic module 50 by the first adhesive tape 70. More specifically, the corner protector placement positioning mechanism 22 is disposed near the photovoltaic module 50 on the first transmission module 10, and is used for fixing the corner protector 60 to be installed and pressing the corner protector 60 against the outer side of the corresponding corner of the photovoltaic module 50, so as to position the corner protector 60 at the corresponding corner of the photovoltaic module 50 before taping. The fixed-length broken adhesive tape assembly 21 is arranged on one side of the corner protector placing and positioning mechanism 22 away from the photovoltaic module 50, and is used for cutting a section of first adhesive tape 70 for adhering and fixing the corner protector 60 at the corresponding corner of the photovoltaic module 50 and turning one end part of the section of first adhesive tape 70 to form a first folding part 71. The tape attaching mechanism 23 is disposed between the fixed-length broken tape assembly 21 and the corner protector mounting and positioning mechanism 22 in a reversible manner, and is used for adsorbing and fixing the first tape 70 to be cut when the first tape 70 is cut off, and attaching the cut first tape 70 to the corner protector 60 and the photovoltaic module 50 after the corner protector 60 is fixed at the corner of the photovoltaic module 50 after the first tape 70 is adsorbed and turned over, specifically, the middle section of the first tape 70 is pressed against the outside of the top corner of the corner protector 60, and the two ends of the first tape 70 are folded in the same direction by taking the top corner of the corner protector 60 as a folding starting point, and are respectively and flatly attached and fixed on the upper surface and the lower surface of the photovoltaic module 50, that is, the first tape 70 is attached along the diagonal line of the corner protector 60.

As shown in fig. 4, the fixed-length adhesive tape breaking assembly 21 mainly includes five parts of a first tape reel frame 211, an upper clamping mechanism 214, a folding mechanism 212, a lower clamping mechanism 215 and an adhesive tape breaking mechanism 213. Specifically, the first tape reel 211 is a conventional disc-shaped structural member rotatable about a horizontal line, and the first tape roll is mounted on the first tape reel 211. The first tape reel 211 of the present embodiment is disposed at the uppermost side, and releases the first adhesive tape 70 downward. The upper clamping mechanism 214, the winding mechanism 212, the lower clamping mechanism 215, and the tape breaking mechanism 213 are all disposed below the first tape reel 211. The winding mechanism 212 is disposed on the tape feeding path of the first tape reel 211, specifically below the discharge end of the first tape reel 211 as shown in fig. 8. That is, the first adhesive tape 70 is pulled vertically downward after being fed out from the first tape reel 211. The purpose of the crimping mechanism 212 is to fold the free end of the length of first adhesive tape 70 to be cut, i.e. the lower end as shown in fig. 8, upwardly toward the end thereof to be cut, i.e. as shown in fig. 8. The lower clamping mechanism 215 is vertically arranged below the first tape reel frame 211 in a lifting manner, and the lower clamping mechanism 215 is used for clamping the free end of the folded first tape 70 to form the first folding part 71 and simultaneously pulling the first tape 70 downwards for a certain length when the first tape 70 descends downwards so that the end to be cut of the first tape 70 is just on the same horizontal plane with the tape breaking mechanism 213. An upper clamping mechanism 214 is provided between the first tape reel 211 and the winding mechanism 212 for clamping the upper end of the end to be cut of the first adhesive tape 70. The tape breaking mechanism 213 is disposed between the upper clamping mechanism 214 and the lower clamping mechanism 215 and is close to the upper clamping mechanism 214, and it should be noted that the tape breaking mechanism 213 is located at a side edge of the first adhesive tape 70 between the upper clamping mechanism 214 and the lower clamping mechanism 215, and is capable of being driven to translate along a horizontal direction towards or away from the first adhesive tape 70, so as to perform a translational motion towards a direction towards the first adhesive tape 70 after the first adhesive tape 70 is stretched to a preset length by the lower clamping mechanism 215, so as to cut the end to be cut of the first adhesive tape 70.

Specifically, as shown in fig. 4 and 6, the crimping mechanism 212 includes a first drive 2121 and first and second clamps 2122 and 2123 that are driven by the first drive 2121 for relative movement, the first and second clamps 2122 and 2123 having a separated open state and a closed state that are closed together. In the open state, the free end of the first adhesive tape 70 passes between the first clamping member 2122 and the second clamping member 2123. For convenience of description and distinction, the front end of the first clamping member 2122 is a first clamping section (not shown) as shown in fig. 6, and the front end of the second clamping member 2123 is a second clamping section (not shown) as shown in fig. 6, and in the closed state, the first clamping section and the second clamping section are relatively clamped on two sides of the free end of the first adhesive tape 70, that is, on two sides in front and back as shown in fig. 6, and are staggered in the vertical direction, that is, one above the other, so that the free end of the first adhesive tape 70 can be folded towards the side of the free end to be cut. Illustratively, in this embodiment, the first clamping section is on the upper side and the second clamping section is on the lower side, so that the free end of the lower end of the first adhesive tape 70 is under the clamping force of the first clamping section and the second clamping section, and the folding, specifically, the upward folding, occurs. Preferably, the first gripping section and the second gripping section are of cylindrical configuration, similar to chopsticks. For the first driving member 2121, a conventional cylinder is optional. In this embodiment, the folding mechanism 212 may be capable of translational movement in a horizontal plane, specifically, horizontally approaching or horizontally moving away from the first adhesive tape 70 between the upper clamping mechanism 214 and the lower clamping mechanism 215. The horizontal moving away is performed so as not to interfere with the movement of the lower clamp mechanism 215 and the first adhesive tape 70 in the process that the lower clamp mechanism 215 clamps the folded free end to form the first folded portion 71 and pulls down by a predetermined length. In the present embodiment, as shown in fig. 6, the folding mechanism 212 and the tape breaking mechanism 213 are both provided on the rear side as shown in the drawing and the folding mechanism 212 is located above the tape breaking mechanism 213.

For the upper clamping mechanism 214, as shown in fig. 4 and 6, a fixed platen 2141 and a movable platen 2142 are oppositely disposed along both surfaces of the first adhesive tape 70, i.e., the left and right surfaces as shown in fig. 8, and a second driving member 2143 that drives the movable platen 2142 to move closer to or away from the fixed platen 2141, i.e., to translate left and right as shown in fig. 8. The fixed 2141 and the movable 2142 are shown spaced apart side-to-side, with the free end of the first tape 70 extending downwardly through the space therebetween. Preferably, a side of the fixed platen 2141 facing the movable platen 2142 is formed with a guide groove (not shown) recessed away from the side of the movable platen 2142, i.e., recessed rightward as shown in fig. 8 and extending along the tape feeding path, i.e., extending downward and penetrating as shown in fig. 8, and correspondingly, one end of the movable platen 2142 facing the fixed platen 2141 is formed with a pressing protrusion (not shown) protruding toward the fixed platen 2141 and matching the guide groove, and the pressing protrusion is embedded in the guide groove to clamp and fix the upper end of the end to be cut of the first tape 70. The same applies to the second driver 2143, which may be a conventional cylinder. Preferably, the fixed platen 2141 is provided with a plurality of first adsorption holes 21411 communicating with the guide groove, and the purpose of the first adsorption holes 21411 is to enable the first adhesive tape 70 to be attached to the fixed platen 2141 when the movable platen 2142 is separated from the first adhesive tape 70. Specifically, when the lower clamping mechanism 215 clamps the first folding portion 71 to pull out the first folding portion downward, the first adhesive tape 70 is absorbed and attached to the guide groove on the fixed pressing plate 2141 by the first absorption hole 21411, so that the first adhesive tape 70 can be prevented from falling out of the guide groove of the fixed pressing plate 2141 while guiding, which is unfavorable for the pressing of the first adhesive tape 70 by the subsequent movable pressing plate 2142.

As for the lower clamping mechanism 215, as shown in fig. 5, it mainly includes a clamping assembly 2151 and a third driver 2152. The clamping assembly 2151 of this embodiment may be a conventional pneumatic clamping block mechanism, and specifically includes a first clamping block 21511 and a second clamping block 21512 that are disposed opposite to each other in the left-right direction as shown in fig. 5, and a clamping block cylinder 21513 disposed below the first clamping block 21511 and the second clamping block 21512 to drive the first clamping block 21511 and the second clamping block 21512 to move closer to or farther from each other. The first and second clamping blocks 21511 and 21512 extend upward and are each formed with a clamping segment at an upper end, and for convenience of description and distinction, the clamping segment at the upper end of the first clamping block 21511 is described as a third clamping segment 215111, and the clamping segment at the upper end of the second clamping block 21512 is described as a fourth clamping segment 215121. The third clamp segment 215111 and the fourth clamp segment 215121 each extend convexly outward. That is, the first clamping block 21511 and the second clamping block 21512 are both inverted L-shaped, with a wide upper end and a narrow lower end, and when the third clamping section 215111 of the first clamping block 21511 and the fourth clamping section 215121 of the second clamping block 21512 are clamped, a space is provided between the third clamping section 215111 of the first clamping block 21511 and the lower side of the fourth clamping section 215121 of the second clamping block 21512, which is formed as an avoidance space (not shown) for providing avoidance to the crimping mechanism 212. That is, when the lower clamping mechanism 215 clamps the folded free end and the unfolded portion so that the folded free end and the unfolded portion are tightly adhered to each other to form the first folded portion 71 after the folding mechanism 212 clamps and folds the free end of the first adhesive tape 70 (the first folded portion 71 is not formed), the folding mechanism 212 is not released, that is, is located in the escape space, and when the lower clamping mechanism 215 pulls the first adhesive tape 70 downward after the first folded portion 71 is formed, the folding mechanism 212 needs to withdraw from the escape space. The purpose of the third drive 2152 is to drive the clamp assembly 2151 upward, i.e., toward the crimping mechanism 212, to clamp the free end that has been folded back into the first fold 71 and to clamp or move downward, i.e., away from the crimping mechanism 212, to pull the first tape 70 downward a predetermined length. For the third driving member 2152, the combination of a rotating motor and a screw rod and a vertical sliding rail (not labeled) are exemplary, the screw rod (not labeled) is vertically disposed and connected to the driving end of the rotating motor (not labeled), and the left end of the clamping block cylinder 21513 of the clamping assembly 2151 is slidably connected to the vertical sliding rail through a slider (not labeled), which is not specifically described or limited in detail. Preferably, the end surface of the third clamping section 215111 of the first clamping block 21511 facing the second clamping block 21512 and the end surface of the fourth clamping section 215121 of the second clamping block 21512 facing the first clamping block 21511 are respectively formed with toothed and bar-shaped anti-slip lines (not labeled), so that the friction force during clamping is increased, and the clamping firmness is improved.

In this embodiment, the two third sucking parts 333 are mainly used to suck the corner protector 60 from the flexible vibration plate 312, adjust the pose of the corner protector 60, and then transplant the corner protector 60 onto the carrier 3321 on the second transmission module 332, and then, the carrier 3321 with the corner protector 60 is conveyed to the right side from the left side as shown in fig. 1 or 17, that is, the side close to the vibration feeding assembly 31, that is, the side far from the flexible vibration plate 312 through the second transmission module 332, and then, the empty carrier 3321 is re-conveyed from the right side to the left side. The two second sucking pieces 331 are used for sucking and transplanting the corner protector 60 on the carrier 3321 onto the corner protector mounting and positioning mechanism 22 of the two corner protector taping modules 20 at the corresponding ends, i.e. the front and rear ends of the right side of the apparatus as shown in fig. 1, when the carrier 3321 is conveyed to the right side of the second transmission module 332. The second transmission module 332 has the same structure as the first transmission module 10, that is, is a guide rail or a transmission belt type transmission structure, and in this embodiment, the carrier 3321 is slidably disposed on the guide rail. In some preferred embodiments, the number of the carriers 3321 is two, the two carriers 3321 are arranged at intervals, and in operation, one carrier 3321 is located at the left side of the second transmission module 332, that is, at the position of picking and placing the third suction member 333 near the side of the flexible vibration disc 312, and the other carrier 3321 is located at the right side of the second transmission module 332, that is, at the position of picking and placing the second suction member 331 far from the side of the vibration feeding assembly 31. The efficiency can be greatly improved.

As shown in fig. 17 and 18, as for the carrier 3321, any carrier 3321 is a flat plate structure, two opposite positioning slots 33211 which are arranged at intervals and extend in a downward concave manner are formed on the flat plate structure, the shape and the size of the positioning slots 33211 are consistent with those of the corner protector 60, the pose of the positioning slots 33211 corresponds to that of the corners at the front end and the rear end of the right side of the photovoltaic module 50 shown in fig. 1, the structural complexity of the second suction piece 331 and the simplicity of the operation can be reduced, and the second suction piece 331 can directly suck the corner protector 60 and only needs to translate and lift without rotating to adjust the pose.

That is, the first suction member 322 and the third suction member 333 of the present embodiment have two positions, namely, just above the flexible vibration plate 312 when the opening edge of the 匚 -shaped frame 320 is located, so as to grasp the corner protector 60 on the flexible vibration plate 312, and the other position is located on the opposite side of the opening edge, where the first suction member 322 and the third suction member 333 are located above the carrier 3321 of the second transmission module 332, so as to place the corner protector 60 on the carrier 3321 and convey the corner protector 60 to the side far from the vibration feeding module 31, i.e. the right side as shown in fig. 1, through the transmission of the second transmission module 332, so that the second suction member 331 is convenient to suck and transplant the corner protector 60 on the carrier 3321 onto the corner protector placement positioning mechanism 22 of the corner protector tape module 20 corresponding to the photovoltaic module 50.

For the first suction piece 322 and the third suction piece 333, both are identical in structure and different from the structure of the second suction piece 331. Since the positions of the two positioning grooves 33211 on the carrier 3321 on the second transmission module 332 of the second feeding assembly 33 are fixed, that is, correspond to the two corners on the right side of the photovoltaic module 50, when the corner protector 60 is conveyed from the left side to the right side of the second transmission module 332 by the carrier 3321 and is sucked by the second suction piece 331 and transferred to the corner protector mounting positioning mechanism 22 of the corresponding corner protector taping module 20, the position of the corner protector 60 does not need to be adjusted any more, so that the third suction piece 333 only needs to vertically lift and horizontally move (including along the first direction and the second direction) without rotating to adjust the position. The first suction piece 322 and the third suction piece 333 have a vertical lifting function and a horizontal moving function, and a rotation function around a vertical line, and the purpose of rotation is to adjust the position of the corner protector 60, because the position of the corner protector 60 is not completely corresponding to the positions of the two corners on the left side of the photovoltaic module 50 and the positions of the two positioning grooves 33211 on the jig, that is, the positions of the two corners on the right side, when the corner protector 60 is sucked from the flexible vibration plate 312. That is, the third suction member 333 should further include a second vertical rotation driving member 3331 driving the third suction member 333 to rotate about a vertical line, a third vertical displacement driving member 3332 driving the third suction member 333 and the second vertical rotation driving member 3331 to vertically lift integrally, and a third horizontal displacement driving member driving the third suction member 333, the second vertical rotation driving member 3331 and the third vertical displacement driving member 3332 to horizontally, that is, in the first direction integrally. And the second suction member 331 includes only the second suction member 331 and the second vertical displacement driving member 3311 driving the second suction member 331 to vertically ascend and descend, and the second horizontal displacement driving member 3312 driving the second suction member 331 and the second vertical displacement driving member 3311 to integrally move in a horizontal, i.e., first direction.

As for the first suction piece 322, the second suction piece 331, and the third suction piece 333, as shown in fig. 14 to 16, four suction cups arranged in an L-shape are included, and two suction cups are corresponding to each arm of the corner protector 60. The construction of the conventional motor and belt combination for first horizontal displacement drive 325, second horizontal displacement drive 3312 and third horizontal displacement drive is not described or limited herein and is readily known and implemented by those skilled in the art. The first, second and third vertical displacement drivers 324, 3311, 3332 may be selected from conventional air cylinders, which are not described or defined herein, as would be readily understood and effected by one skilled in the art. The first vertical rotation driver 323 and the second vertical rotation driver 3331 may be selected from conventional rotating electric machines, which are not described and limited herein, and are easily known and implemented by those skilled in the art.

It should be noted that, the two first suction members 322 are independent, that is, one first suction member 322 corresponds to one first vertical rotation driving member 323, one first vertical displacement driving member 324, and one first horizontal displacement driving member 325. Similarly, the two third suction members 333 are independent, i.e. one third suction member 333 corresponds to one second vertical rotation driving member 3331, one third vertical displacement driving member 3332 and one third horizontal displacement driving member. The two second suction members 331 are also independent, i.e. each correspond to one second vertical displacement driving member 3311 and one second horizontal displacement driving member 3312. Since the two first suction members 322 and the two third suction members 333 are disposed on the first truss 321, in order to reduce the complexity of the structure and avoid interference during movement, in this embodiment, one of the first suction members 322 and one of the third suction members 333 are integrated together, the other first suction member 322 and the other third suction member 333 are integrated together, and the two third suction members 333 are disposed inside the two first suction members 322, that is, the two first suction members 322 are disposed at the front and rear ends as shown in fig. 14. Specifically, as shown in fig. 1, the first suction member 322 and the third suction member 333 at the front end are mounted on the same fixed substrate and driven to move in the horizontal direction, that is, in the first direction, and similarly, the first suction member 322 and the third suction member 333 at the rear end are mounted on the same fixed substrate (not shown) and driven to move in the horizontal direction, that is, in the first direction. That is, the third horizontal displacement driving member and the first horizontal displacement driving member 325 are the same driving member, and are driving motors as shown in fig. 14 and 16.

Compared with the feeding module 30 in the prior art in the background art, the feeding module 30 of the embodiment only needs to set up a storage bin 311 and a flexible vibration disc 312 on one side of the first transmission module 10, two vibration feeding discs are not needed, transplanting and feeding of corner protectors 60 of four corners of the photovoltaic module 50 are respectively realized through two sets of feeding modules, and the structure is simpler and the occupied area is smaller. Through tests, the beat of the device of the embodiment is about 16s, and the efficiency is high.

The structure of the side tape attaching module 40 is identical to that of embodiment 2, and details are omitted, except that the number of the side tape attaching modules 40 is different, and in this embodiment, the number of the side tape attaching modules 40 is two and is staggered relatively.
