AI Technical Summary
During the production of photovoltaic modules, the PTFE cloth is not mechanically positioned on the transfer platform, which makes it easy for it to shift during material handling. This may cause the lead wires to be unable to pass through the opening smoothly, which in turn leads to deformation or breakage of the PTFE cloth.
The PTFE cloth mechanical positioning mechanism includes a connecting plate, a fixing plate, a straightening cylinder, a long-side gripper, and a short-side gripper. The straightening cylinder drives the gripper to move synchronously to straighten the PTFE cloth, and the guide column and suction cup are used for multi-stage adsorption and fixation to ensure the precise guidance and dynamic positioning of the PTFE cloth.
It achieves fully automatic positioning of PTFE cloth on the transfer platform, prevents deviation, ensures that the lead wire feet can pass smoothly through the opening, avoids deformation or breakage of PTFE cloth, and improves the accuracy and stability of positioning.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module production technology, specifically to a PTFE mechanical positioning mechanism. Background Technology
[0002] In the assembly and production process of photovoltaic modules, one of the steps is to place PTFE between the leads and the module, and then smooth the leads. The purpose of this is to protect the components and prevent adhesive overflow.
[0003] In the existing technology, PTFE cloth is placed directly on the transfer platform without mechanical positioning. When the PTFE cloth is picked up, it will be offset, and there is a possibility that the lead wires may not be able to pass through the openings in the PTFE cloth smoothly. If the lead wires cannot pass through the openings in the PTFE cloth, it is very likely to deform the top of the PTFE cloth or cause it to deform or break. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0029] Please see Figures 1-3 As shown, the PTFE mechanical positioning mechanism provided in this embodiment of the present invention includes a connecting plate 1, and a fixing plate 2 is fixedly connected to one side of the connecting plate 1; the device is installed and fixed by connecting the connecting plate 1 to the transfer platform.
[0030] A aligning cylinder 3 is installed at the bottom of the fixed plate 2. The output end of the aligning cylinder 3 is equipped with a long-side gripper 5 and a short-side gripper 6. The model of the aligning cylinder 3 is MHS4-16D, which is an existing device.
[0031] A guide seat 4 is fixedly connected to the top of the fixed plate 2, and a PTFE cloth 7 is provided on the top of the guide seat 4.
[0032] The PTFE cloth 7 is picked up by the material handling mechanism and placed on the top of the guide seat 4 fixed on the transfer platform. The straightening cylinder 3 drives a pair of long-side grippers 5 and short-side grippers 6 to move synchronously towards the center to straighten the PTFE cloth 7. The inner sides of the long-side grippers 5 and short-side grippers 6 are provided with V-shaped guide grooves to correct the edge of the PTFE cloth 7 and reduce the positional deviation of the PTFE cloth 7 after straightening.
[0033] Preferably, a pair of guide posts 8 are fixedly provided on the top of the guide seat 4, and the top of the guide posts 8 is set in a conical shape.
[0034] The bottom of the correcting cylinder 3 is fixedly connected to a support plate 12, and a pair of straight holes 13 are opened inside the PTFE cloth 7. The diameter of the guide post 8 matches the straight holes 13.
[0035] During the alignment process, the conical head of the guide post 8 guides the PTFE cloth 7 through the slot 13 to move downward, ensuring that the slot 13 is fully fitted with the bottom of the guide post 8, thereby reducing the offset of the PTFE cloth 7.
[0036] Preferably, the guide seat 4 is equipped with a pair of suction cups 9, which are located on both sides of the bottom of the PTFE cloth 7. The suction cups 9 are SMC series industrial vacuum suction cups, which have a modular design for vacuum adsorption and are suitable for high-frequency gripping in automated production lines. They belong to existing equipment.
[0037] The suction cup 9 at the bottom of the PTFE cloth 7 activates negative pressure adsorption to fix the position of the PTFE cloth 7 and prevent subsequent mechanical vibration from causing displacement. The surface of the suction cup 9 is designed with contoured grooves to match the texture of the PTFE cloth 7, improve the coverage of the contact area, and avoid local stress concentration.
[0038] Preferably, the guide seat 4 has a first guide groove 10 on both sides, and the outer side of the long side gripper 5 is slidably connected to the inner wall of the first guide groove 10.
[0039] The guide seat 4 has second guide grooves 11 on both sides away from the first guide groove 10, and the outer side of the short side gripper 6 is slidably connected to the inner wall of the second guide groove 11.
[0040] The long-side gripper 5 and the short-side gripper 6 are guided and limited by the first guide groove 10 and the second guide groove 11.
[0041] The working principle of this utility model is as follows: The PTFE cloth 7 is gripped by the material handling mechanism and placed on the top of the guide seat 4 fixed on the transfer platform. The alignment cylinder 3 drives a pair of long-side grippers 5 and short-side grippers 6 to move synchronously towards the center, aligning the PTFE cloth 7. V-shaped guide grooves are provided on the inner sides of the long-side grippers 5 and short-side grippers 6 to correct the edges of the PTFE cloth 7 and reduce the positional deviation after alignment. During the alignment process, the conical head of the guide post 8 guides the slotted hole 13 of the PTFE cloth 7 downwards, ensuring that the final slotted hole 13 is completely fitted with the bottom of the guide post 8, reducing... The offset of PTFE cloth 7 is addressed by the negative pressure adsorption activated by the suction cup 9 at the bottom of PTFE cloth 7, which fixes the position of PTFE cloth 7 and prevents subsequent mechanical vibration from causing offset. The surface of suction cup 9 is designed with contoured grooves to adapt to the texture of PTFE cloth 7, improve the coverage of the contact area, and avoid local stress concentration. After the PTFE cloth 7 is positioned, the system sends a ready signal to the material picking module to pick up the PTFE cloth 7. This achieves a fully automatic positioning effect of PTFE cloth 7 through the integration of precision guidance, dynamic correction, and multi-stage adsorption technologies, solving the problem of PTFE cloth 7 offset on the transfer platform.
