[0001] The utility model relates to the field of automation equipment, in particular to a device for installing PTFE cloth and smoothing busbars. Background Art

[0002] There are busbars protruding from the surface of photovoltaic modules (hereinafter referred to as modules). In order to prevent glue overflow at the location where the busbars protrude, PTFE cloth is usually laid at the location where the modules protrude from the busbars. After the PTFE cloth is installed on the busbars, the busbars need to be pressed and smoothed to cover them on top of the PTFE cloth.

[0003] The current method is to use installation equipment to install the PTFE cloth on the busbar. After the PTFE cloth is installed, the busbar is pressed and smoothed manually. However, this operation has at least the following disadvantages:

[0004] 1. The busbar is a thin metal sheet. When installing the PTFE sheet through automated equipment, it is easy to cause the busbar to be twisted, resulting in the busbar passing accurately through the pre-opened holes in the PTFE sheet, and the success rate of PTFE sheet installation is low;

[0005] 2. The manual pressing and smoothing method has low production efficiency and high labor intensity for workers.

[0006] Therefore, the present application provides a PTFE cloth installation and busbar smoothing device to solve the technical problems in the prior art. Utility Model Content

[0035] The following is combined with Figure 1-5 , further explain this application in detail.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 The PTFE cloth installation and busbar smoothing equipment includes a frame 1, on which are provided an installation and smoothing mechanism 2, an adaptive positioning mechanism, a moving assembly and a conveying mechanism. The moving assembly includes an X-axis moving assembly 3, a Y-axis moving assembly 4 and a Z-axis moving assembly 5. The conveying mechanism is used to transport photovoltaic modules. The surface of the photovoltaic modules has a busbar. The installation and smoothing mechanism 2 is used to install the PTFE cloth on the busbar and smooth the busbar and cover the surface of the PTFE cloth. The moving assembly is used to drive the installation and smoothing mechanism 2 to move along the X-axis, Y-axis and Z-axis of the frame 1. The installation and smoothing mechanism 2 and the adaptive positioning mechanism share the X-axis moving assembly 3 and the Y-axis moving assembly 4. The Z-axis moving assembly 5 includes a vertically arranged servo cylinder 6. A horizontal plate 7 is provided at the bottom of the servo cylinder 6. The installation and smoothing mechanism 2 is arranged at the bottom of the horizontal plate 7.

[0037] Reference Figure 2 and Figure 3The installation and smoothing mechanism 2 includes an inner clamping jaw 8, an outer clamping jaw 9, a limiting assembly, a first clamping jaw cylinder 10 for driving the inner clamping jaw 8 to open and close, and a second clamping jaw cylinder 11 for driving the outer clamping jaw 9 to open and close. When the outer clamping jaw 9 is closed, the inner side of the outer clamping jaw 9 abuts against the outer side of the inner clamping jaw 8, and the bus bar is located between the outer clamping jaw 9 and the inner clamping jaw 8. The end of the inner clamping jaw 8 close to the bus bar has an inclined surface, so that the inner clamping jaw 8 can be more easily extended between the two bus bars. The contact surface between the outer clamping jaw 9 and the inner clamping jaw 8 is a flat surface. When the inner clamping jaw 8 is in the open state, the two inner clamping jaws 8 translate relative to each other and move away from each other. When the outer clamping jaw 9 is closed, the contact surface between the inner clamping jaw 8 and the outer clamping jaw 9 squeezes the bus bar, thereby limiting the bottom of the bus bar, so that the PTFE cloth can be more easily installed on the bus bar. When the outer clamping jaw 9 is in the open state, the two outer clamping jaws 9 rotate 90 degrees in opposite directions.

[0038] Reference Figure 4 and Figure 5 , a horizontally arranged first slide cylinder 15 is provided at the bottom of the cross plate 7, a mounting plate 16 is provided at the bottom of the first slide cylinder 15, the first clamping jaw cylinder 10 and the second clamping jaw cylinder 11 are both mounted on the bottom of the mounting plate 16, the first slide cylinder 15 is used to drive the inner clamping jaw 8 and the outer clamping jaw 9 to move toward or away from the bus bar, the installation and smoothing mechanism 2 also includes a second slide cylinder 18 and a guide plate 17, the second slide cylinder 18 is used to drive the suction cup 31 to move up and down along the Z axis, the suction cup 31 includes two suction nozzles 23, the guide plate 17 has two and both are vertically arranged, the two guide plates 17 correspond to the two bus bars respectively, the second slide The cylinder 18 is fixed to the Z-axis moving component 5. The second slide cylinder 18 is connected to an extension plate 19, which is connected to a fixed block 20. The fixed block 20 is slidably connected to the guide piece 17. Grooves 21 are provided on both sides of the guide piece 17 near one end of the bus bar. A protrusion 22 is provided at the end of the guide piece 17 near the bus bar, so that the PTFE cloth can be better separated from the guide piece 17 and the contact area between the guide piece 17 and the bus bar is increased. The guide piece 17 is located between the two suction nozzles 23, and the suction cup 31 is located at the bottom of the fixed block 20. A compression spring 30 is connected between the suction cup 31 and the fixed block 20. The guide piece 17 passes through the fixed block 20 and the suction cup 31. By providing the compression spring 30, when the second slide drives the suction cup 31 to move close to the component, it is not easy to make rigid contact with the component and is not easy to be damaged.

[0039] The limiting assembly includes a telescopic cylinder 12, a fixed plate 13 and a steel needle 14. The telescopic cylinder 12 is fixed to the horizontal plate 7. The movable end of the telescopic cylinder 12 is connected to the fixed plate 13. The fixed plate 13 is used to install the steel needle 14. The steel needle 14 is arranged horizontally. The steel needle 14 is located on the other side of the busbar relative to the inner clamping jaw 8 and the outer clamping jaw 9 to limit the busbar. The telescopic cylinder 12 is used to drive the steel needle 14 to move toward or away from the busbar.

[0040] The adaptive positioning mechanism corresponds to the bus bar. In this application, there are three groups of bus bars, and the corresponding installation and smoothing mechanism 2 also has three groups. The adaptive positioning mechanism also has three groups. The adaptive positioning mechanism includes a visual camera 24, a light source 25 frame 26 and a camera mounting plate 27. The light source 25 is used to illuminate the corresponding bus bar. The visual camera 24 is used to take pictures of the bus bar and transmit the pictures to the terminal image acquisition system. The acquisition system transmits the image to the computer. The computer calculates the pixel deviation between the center of the image and the center between the two bus bars, and controls the movement of the installation and smoothing mechanism 2 to achieve position compensation by controlling the X-axis, Y-axis and Z-axis moving mechanisms, so that the inner clamp 8 can accurately penetrate from the middle position of the two bus bars. The image is taken by the visual camera 24, and the position deviation is calculated through noise reduction, image processing and other algorithms, and the movement of the control mechanism is an existing mature technology, and this application will not go into details. The visual camera 24 is installed at the bottom of the camera mounting plate 27. Both sides of the camera mounting plate 27 are located in the vertical frame 26. The camera mounting plate 27 is movably connected to the vertical frame 26. The side wall of the vertical frame 26 is provided with an arc groove 28. The side wall of the camera mounting plate 27 close to the vertical frame 26 is provided with a threaded hole 29. Through this arrangement, the shooting angle of the visual camera 24 can be adjusted. After the adjustment is completed, the bolts are passed through the arc groove 28 in sequence and tightened in the threaded hole 29 to fix the angle.

[0041] The working process of the PTFE cloth installation and busbar smoothing equipment provided by the present application is as follows: the installation and smoothing mechanism 2 first absorbs the PTFE cloth to be installed through the suction cup 31, and then moves in the direction close to the busbar, and then the installation and smoothing mechanism 2 moves downward for a distance. At the beginning, the distance between the two busbars gradually becomes smaller from the bottom to the top, and the entry point of the inner clamping jaw 8 is found through the adaptive positioning mechanism. At this time, the outer clamping jaw 9 is in an open state and rotated 90 degrees. The telescopic cylinder 12 is in an extended state. At this time, the steel needle 14 is away from the busbar and is inserted into the inner After the clamping jaws 8 enter between the bus bars, they squeeze the middle of the bus bars, causing the tops of the two bus bars to gradually move away from each other, and then the telescopic cylinder 12 shortens, causing the steel needle 14 to limit the other side of the bus bar, and then the outer clamping jaws 9 close. At this time, the outer clamping jaws 9, the inner clamping jaws 8 and the steel needle 14 limit the bus bars in multiple directions. The two guide plates 17 are located above the bus bars and limit the two bus bars respectively, so that the bus bars are not easily offset. The second slide cylinder 18 moves downward, driving the suction cup 31 to move downward. When the suction cup 31 moves to the top of the inner clamping jaw 8 and the outer clamping jaw 9, the first slide cylinder 15 drives the inner and outer clamping jaws 9 to move away from the bus bar, the telescopic cylinder 12 drives the steel needle 14 to move away from the bus bar, the second clamping jaw cylinder 11 drives the outer clamping jaw 9 to turn ninety degrees, and then the suction cup 31 continues to move downward, thereby installing the PTFE cloth on the bus bar, and then the second slide cylinder 18 moves upward, driving the suction cup 31 to move upward, the steel needle 14 approaches the bus bar again and abuts against the side of the bus bar, and the inner clamping jaw 8 penetrates again. Inserted between the two bus bars, the Z-axis moving assembly 5 drives the inner clamping jaw 8 downward and close to the bottom of the bus bar, and then the first clamping jaw cylinder 10 drives the inner clamping jaw 8 to open, and the action of installing the PTFE cloth and smoothing the bus bar is completed. The smoothed bus bar is located above the PTFE cloth, and the installation of the PTFE cloth and the smoothing of the bus bar are quickly completed. In addition, the inner clamping jaw 8, the outer clamping jaw 9 and the steel needle 14 have a good limiting effect on the bus bar, so that the bus bar is not easily offset, thereby improving the success rate of installing the PTFE cloth.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
