The embodiment provides a dispensing carrier. As shown in fig. 1, the dispensing carrier comprises an adsorption mechanism 1, a support frame 2, a screen body support assembly 3 and an FPC support assembly 4, wherein the screen body support assembly 3 and the FPC support assembly 4 are fixedly arranged on the support frame 2. The adsorption mechanism 1 is arranged on the support frame 2, and the screen body support assembly 3 and the FPC support assembly 4 are respectively positioned on two sides of the adsorption mechanism 1.

The screen body supporting component 3 of the dispensing carrier can support the screen body of the OLED display screen and support the FPC board through the FPC supporting component 4, so that the bending area of the FPC board falls on the adsorption mechanism 1, after the bending area of the FPC board is adsorbed and fixed through the adsorption mechanism 1, dispensing operation can be carried out on the bending area, and the position requiring dispensing is called as a dispensing area.

In order to improve the applicability of the dispensing carrier, the FPC supporting assembly 4 includes a first fixing frame 41, a second fixing frame 42 and an adsorbing member 43, the first fixing frame 41 is fixedly connected with the supporting frame 2, the second fixing frame 42 is slidably disposed on the first fixing frame 41 along a second direction (Y direction in the drawing), the adsorbing member 43 is slidably disposed on the second fixing frame 42 along a first direction (X direction in the drawing), and the second direction is disposed at an included angle with the first direction.

The second fixing frame 42 and the adsorbing member 43 of the FPC supporting assembly 4 can be suitable for FPC boards with different sizes, so that the FPC boards are prevented from being bent and the adsorbing mechanism 1 cannot be tightly adsorbed.

Specifically, the FPC supporting assembly 4 includes two first fixing frames 41 that the interval set up, and the waist type hole that the major axis extends along the second direction is seted up to first fixing frame 41, and the both ends of second fixing frame 42 all threaded connection has the screw, and the screw passes waist type hole, so can be after loosening the screw, need not take apart completely just can adjust the position of second fixing frame 42.

It is understood that the display screen includes, in addition to the FPC board to be connected to the circuit board after bending, an FPC board to be connected to other components, for convenience of distinction, the FPC board to be connected to the circuit board after bending is referred to as a first PFC board, the FPC board to be connected to other components is referred to as a second FPC board, and the second FPC board is generally disposed on the opposite side of the first FPC board, so that the second FPC support assembly needs to provide support for the second FPC board.

Preferably, the screen support assembly 3 includes a plurality of screen support plates 31, and the plurality of screen support plates 31 are detachably connected with the support frame 2. Because the screen sizes of the display screen are different, the positions of the second FPC boards may be different, and in order not to damage the electronic components on the second FPC boards, the corresponding screen support boards 31 may be selectively removed or installed according to the sizes of the products.

Because the first FPC board of different display screens is different, in order to guarantee closely adsorb the product on the microscope carrier, generally need to customize the point gum microscope carrier according to the specific size of display screen and first FPC board to guarantee that the absorption scope of point gum microscope carrier is more suitable, need to change the appropriate point gum microscope carrier of absorption size in step when the product trades the type. On one hand, project cost can be increased, on the other hand, the parallelism of the carrier and the dispensing head needs to be readjusted when the carrier is replaced, product changing time is increased, and customer productivity is reduced.

In order to ensure the stability of the screen body, a through hole is formed in the screen body supporting plate 31, and a sucker 32 is arranged in the through hole, so that the screen body is adsorbed.

In order to solve the above-mentioned problems, the present embodiment provides an adsorption mechanism, as shown in fig. 2 and 3, the adsorption mechanism 1 includes a carrying table 11 and an adjusting assembly 12. The bearing table 11 is internally provided with a negative pressure cavity 111, the table surface of the bearing table 11 is provided with a plurality of adsorption holes 112 which are arranged at intervals along the first direction, the bearing table 11 is also provided with an air suction hole 113, and the air suction hole 113 and the adsorption holes 112 are communicated with the negative pressure cavity 111; the adjusting component 12 includes a slider 121, the slider 121 is slidably disposed in the negative pressure cavity 111 along the first direction and is in sealing contact with the inner wall of the negative pressure cavity 111, the negative pressure cavity 111 on one side of the slider 121 forms a negative pressure space 114, the air suction hole 113 is communicated with the negative pressure space 114, and the slider 121 can adjust the number of suction holes 112 communicated with the negative pressure space 114 through sliding.

In the suction mechanism 1, the number of suction holes 112 communicating with the negative pressure space 114 can be adjusted by sliding the slider 121 of the adjusting unit 12, so that the number of suction holes 112 capable of generating a suction effect is changed, that is, the suction range is changed, when the negative pressure space 114 is sucked through the suction hole 113. When the product is required to be changed, the sliding block 121 is only required to be adjusted according to the size of the FPC board of the new display screen, so that the adsorption mechanism 1 can provide a proper adsorption range, the adsorption mechanism 1 is not required to be replaced, the cost is reduced, the time for readjusting the parallelism of the dispensing head and the dispensing carrier is saved, and the production efficiency is improved.

In the present embodiment, the openings of the adsorption holes 112 in the negative pressure chamber 111 are also arranged at intervals along the first direction, so that adjusting the size of the negative pressure space 114 can control the number of adsorption holes 112 that can produce the adsorption effect, thereby changing the adsorption range. It is understood that the optimal adsorption range is that the adsorption holes 112 in the range covered by the dispensing region of the first FPC board can generate adsorption effects, while the adsorption holes 112 in the range not covered by the dispensing region of the first FPC board can not generate adsorption effects, so that the adsorption force generated by the negative pressure space 114 is uniformly distributed below the dispensing region of the first FPC board.

As shown in fig. 3, the adjusting assembly 12 further includes a screw 122, where the screw 122 is disposed in the negative pressure chamber 111 and is rotatably connected to the bearing table 11, and the screw 122 passes through the slider 121 and is screwed to the slider 121. By rotating the screw 122 and controlling the number of turns of the screw 122, the slider 121 can be made to move in the first direction, and the distance of movement of the slider 121 can be accurately controlled, thereby realizing the adjustment of the size of the negative pressure space 114.

Specifically, the negative pressure cavity 111 of the bearing table 11 extends to the end of the bearing table 11 along the first direction toward two ends, so in order to fix the screw 122 and limit the sliding block 121, the adsorption mechanism 1 further includes two blocking pieces 13, the two blocking pieces 13 are respectively fixedly disposed at two ends of the negative pressure cavity 111, and two ends of the screw 122 are respectively rotatably connected with one blocking piece 13.

Further, at least one end of the screw 122 penetrates the corresponding blocking member 13 and is fixedly provided with a rotating member 14, so that an operator can rotate the screw 122 to adjust the position of the slider 121, and the rotating member 14 can reduce the force required by the operator when rotating the screw 122, thereby reducing the working strength. In order to improve efficiency, the screw 122 may be driven to rotate by a rotating motor.

It will be appreciated that the carrying platform 11 further comprises an anti-rotation structure which enables the slider 121 to slide only in the first direction relative to the carrying platform 11, thereby preventing the slider 121 from being moved in the first direction or from being moved by a misalignment distance due to the rotation of the slider 121 along with the screw 122.

A common anti-rotation structure may be provided with a guide post in the negative pressure cavity 111, where the axial direction of the guide post is parallel to the axial direction of the screw 122, and the guide post passes through the slider 121 and is in sealing abutment with the slider 121. However, the use of the guide post as the anti-rotation structure increases the complexity of the structure, and increases the cost due to the additional sealing structure between the slider 121 and the guide post.

As shown in fig. 4, in order to solve the above-mentioned problem, in the present embodiment, a radial cross section of the negative pressure space 114 along the first direction is oblong to form an anti-rotation structure. It will be appreciated that the radial cross-section of the negative pressure space 114 in the first direction may also be elliptical.

Since the shape of the radial cross section of the negative pressure space 114 is not circular, the slider 121 can be effectively prevented from rotating relative to the stage 11, and an anti-rotation effect is achieved. And the radial cross section shape of the negative pressure space 114 is set to be oblong or elliptical, so that the inner wall of the negative pressure space 114 can be ensured to be a smooth curved surface, the sealing is facilitated, and the abrasion to a sealing structure is small.

Preferably, the side wall of the sliding block 121 is sleeved with a sealing ring 123, and the sealing ring 123 is in sealing abutting connection with the inner wall of the negative pressure cavity 111. The seal ring 123 is a seal structure between the slider 121 and the inner wall of the negative pressure chamber 111, and can ensure the air tightness between the negative pressure chambers 111 at both ends of the slider 121.

As shown in fig. 5, the side wall of the slider 121 is provided with at least two sealing grooves 1211 spaced apart along the first direction, and each sealing groove 1211 is sleeved with a sealing ring 123. The sealing grooves 1211 can fix the sealing ring 123 in the first direction, so that the sliding block 121 is prevented from sliding relative to the sealing ring 123 to be separated when sliding in the first direction, and at least two sealing grooves 1211 can form multiple sealing by a plurality of sealing rings 123, so that the sealing reliability is improved.

As shown in fig. 3, the adjusting assembly 12 includes two sliding blocks 121, the negative pressure chamber 111 between the two sliding blocks 121 is a negative pressure space 114, the screw 122 includes two threaded sections 1221 with opposite directions, the screw 122 passes through the two sliding blocks 121, and the two threaded sections 1221 are respectively in threaded connection with one sliding block 121. By the two sliders 121 sliding together, the negative pressure space 114 can be prevented from being biased to one end, thereby facilitating the arrangement of the screen of the display screen on the screen support assembly 3. And the two sliding blocks 121 are driven simultaneously by the same screw 122, so that not only can the adjusting efficiency be improved, but also the two sliding blocks 121 can be ensured to synchronously move.

Further, the air extraction holes 113 are equidistant from the two sliders 121. When the two sliders 121 move synchronously, even if the distance between the two sliders 121 is small, the suction holes 113 can generate negative pressure in the negative pressure space 114, so that the corresponding suction holes 112 generate suction effect, and the applicability of the suction mechanism 1 and the dispensing carrier is further expanded.

As shown in fig. 2, in the present embodiment, four groups of adsorption holes 112 are formed in the carrying platform 11, each group of adsorption holes 112 is disposed at intervals along the first direction, two adjacent groups of adsorption holes 112 are disposed at intervals along the second direction, and the spacing between one group of adsorption holes 112 and the other three groups of adsorption holes 112 is larger, and the spacing is used for placing the dispensing area of the first FPC board, so that the lower part of the dispensing area is ensured to be a plane.

The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
