Abstract
Description
Technical Field
[0001] The invention relates to a matching device for solar backboard repairing equipment, and in particular to a paper folding mechanism applied to the solar backboard repairing equipment. Background Art
[0002] During the use of today's solar back panels, the outermost protective paper of the solar back panels is most susceptible to damage. When the outermost protective paper of the solar back panels is damaged, the main repair method today is to manually re-paste the protective paper for repair. The work process is complicated, time-consuming and labor-intensive, and the work intensity of the staff is high. In order to reduce the labor intensity of the staff, some businesses have begun to use solar back panel repair machines to repair solar back panels.
[0003] Today's robots used in solar backplane repair machines require a lot of manual assistance in folding the protective paper during the pasting process so that the protective paper can be placed inside the solar backplane. The folding process will cause creases on the protective paper, which may cause waste in severe cases and reduce the yield rate. In addition, during the pasting process, it is necessary to manually remove the bubbles between the protective paper and the solar backplane and manually cut a notch at one end of the protective paper (the notch is to avoid the electrical connection device on the solar backplane). The work intensity of the staff is very high during the entire process. Summary of the invention
[0004] In order to solve the above technical problems, we proposed a paper folding mechanism used in solar back panel repair equipment, with the purpose of reducing the labor intensity of the staff, eliminating the need for manual folding and manual bubble removal, and being able to smoothly fit the protective paper inside the solar back panel to improve the yield rate.
[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0009] A connecting rod is rotatably provided on the bracket, and the end of the connecting rod is rotatably connected to the blade;
[0010] The base plate and the four blades are provided with elastic adsorption heads, a vacuum device connected to the elastic adsorption head is provided on one side of the top surface of the base plate, a sponge layer is provided on the bottom surfaces of the base plate, the four baffles and the four blades, and the adsorption end of the elastic adsorption head protrudes from the sponge layer;
[0011] The four corners of the support frame are each provided with a first cylinder, and a pressing frame is commonly fixed on the working rods of the four first cylinders;

A second cylinder is provided at the end of the moving block, and a laser cutting head is provided on the working rod of the second cylinder.
[0013] Preferably, the blade is trapezoidal in shape.
[0014] Preferably, every two non-adjacent blades are symmetrical to each other.
[0015] Preferably, there is one servo motor, which is arranged in the middle of the support frame. Two connecting rods are rotatably provided on the four sides of the support frame, and the connecting rods on each side of the support frame are rotatably connected to a blade respectively.
[0016] Preferably, the connecting rod includes an upper rod and a lower rod, the top of the upper rod is rotatably connected to the bracket, the bottom of the lower rod is rotatably connected to the base plate, the lower part of the upper rod is provided with a groove, an adjusting nut is rotatably provided in the groove, and the top of the lower rod is provided with a screw corresponding to the adjusting nut.
[0017] According to another embodiment of the present invention, the number of the servo motors is four, and the servo motors are arranged on support frames at the top of four sides of the substrate.
[0018] Through the above technical scheme, the transmission mechanism of the solar back panel repair machine pushes the support frame downward to make the elastic adsorption head fit on the protective paper, and then the protective paper is adsorbed by the cooperation of the elastic adsorption head and the vacuum device; when the paper folding mechanism is unloading, the transmission mechanism of the solar back panel repair machine pushes the support frame to move to a predetermined position and presses down, and then the servo motor drives the screw rod to rotate, pushing the support frame downward, causing the four blades to rotate downward, shrinking the edge of the adsorbed protective paper inward (that is, reducing the vertical projection area of the protective paper to facilitate placing it in a solar back panel shell that is smaller than the flattened area of the protective paper), so that the adsorbed protective paper can be transported to the solar back panel without contacting the solar back panel shell, and then the servo motor drives the screw rod to rotate, and the four blades are slightly lifted upward to flatten the adsorbed protective paper and fit it in the solar back panel, and the bubbles are exhausted, and the servo motor drives the screw rod to rotate again.

Among them, the sponge layer and the elastic adsorption head do not damage the surface of the protective paper, preventing the folding mechanism from scratching the protective paper. The sponge layer can also cooperate with the blades to discharge the bubbles between the protective paper and the solar back panel. There is no need for manual bubble discharge, which further reduces the labor intensity of the staff.

[0028] The specific implementation of the present invention is further described in detail below with reference to the schematic diagram.
[0029] Example 1.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a paper folding mechanism used in a solar back panel repair device includes a substrate 1, and a blade 11 is rotatably provided on each of the four sides of the substrate 1. A baffle 100 is provided on the substrate 1 between two adjacent blades 11. The substrate 1, four baffles 100 and four blades 11 together form a gripping workbench. The shape of the blade 11 is trapezoidal, which ensures that the paper folding mechanism can absorb the protective paper.
[0031] A polished rod 2 is fixedly provided on the top surface of the base plate 1, and a support frame 21 connected to the transmission mechanism of the solar backboard repairing machine is provided on the top of the polished rod 2. The support frame 21 can ensure the overall movement of the paper folding mechanism.
[0032] A servo motor 22 is disposed on the support frame 21 , and a screw rod 23 axially connected to a working rod of the servo motor 22 is rotatably disposed on the base plate 1 .
[0033] A bracket 24 sleeved on the screw rod 23 is slidably provided on the polished rod 2 between the support frame 21 and the base plate 1 , and the bracket 24 and the base plate 1 are parallel to each other.
[0034] Two connecting rods 25 are rotatably provided on the four sides of the bracket 24 , and the ends of the connecting rods 25 on the four sides of the bracket 24 are rotatably connected to the four blades 11 respectively.
[0035] An elastic adsorption head 3 is provided on the substrate 1 and the four blades 11. A vacuum device 31 connected to the elastic adsorption head 3 is provided on one side of the top surface of the substrate 1. A sponge layer 32 is provided on the bottom surfaces of the substrate 1, the four baffles 100 and the four blades 11. The adsorption end of the elastic adsorption head 3 protrudes from the sponge layer 32. The sponge layer 32 and the elastic adsorption head 3 do not damage the surface of the protective paper, thereby preventing the folding mechanism from scratching the protective paper. The sponge layer 32 can also discharge the bubbles between the protective paper and the solar back panel, without the need for manual bubble discharge, further reducing the labor intensity of the staff.
[0036] Every two non-adjacent blades 11 are symmetrical to each other.
[0037] The connecting rod 25 includes an upper rod 251 and a lower rod 252. The top of the upper rod 251 is rotatably connected to the bracket 24, and the bottom of the lower rod 252 is rotatably connected to the base plate 1. A groove 253 is provided at the lower part of the upper rod 251, and an adjusting nut 254 is rotatably provided in the groove 253. A screw 255 corresponding to the adjusting nut 254 is provided at the top of the lower rod 252, which facilitates the staff to adjust the distance between the bracket 24 and the base plate 1, saves the time of replacing accessories, and improves production efficiency.
[0038] The four corners of the support frame 21 are each provided with a first cylinder 4, and a pressing frame 41 is fixed on the working rods of the four first cylinders 4. The pressing frame 41 can support the protective paper when gluing. When the paper folding mechanism is unloading, the working rod of the first cylinder 4 will shrink upward to lift the pressing frame 41 upward.
[0039] A left-right moving device 5 is provided on the substrate 1, and a front-back moving device 6 is slidably provided on the left-right moving device 5. A moving block 61 is slidably provided on the front-back moving device 6. A second cylinder 62 is provided at the end of the moving block 61. A laser cutting head 63 is provided on the working rod of the second cylinder 62. The laser cutting head 63 can automatically cut the incision on the protective paper.
[0040] The working process of the origami mechanism:
[0041] When the paper folding mechanism is taking materials, the transmission mechanism of the solar back panel repair machine pushes the support frame 21 downward to make the elastic adsorption head 3 fit on the protective paper, and then the protective paper is adsorbed by the cooperation of the elastic adsorption head 3 and the vacuum device 31; when the paper folding mechanism is unloading materials, the transmission mechanism of the solar back panel repair machine pushes the support frame 21 to move to a predetermined position and presses it downward, and then drives the screw rod 23 to rotate through the servo motor 22, pushing the bracket 24 downward, so that the four blades 11 rotate downward, and the edge of the adsorbed protective paper is reduced inward (that is, the vertical projection area of the protective paper is reduced to facilitate the placement of the protective paper larger than the unfolded plane). The adsorbed protective paper can be transported into the solar back panel without contacting the solar back panel shell, and then the servo motor 22 drives the screw rod 23 to rotate, and the four blades 11 are slightly lifted upward to flatten and fit the adsorbed protective paper into the solar back panel, and the bubbles are exhausted, and the servo motor 22 drives the screw rod 23 to rotate again, and the four blades 11 are reset to complete the fitting, without manual folding, which reduces the labor intensity of the staff, and can fit the protective paper into the solar back panel smoothly without creases, thereby improving the yield rate.
[0042] The above are the structural characteristics and effects of a paper folding mechanism used in solar back panel repair equipment. Its advantages are: no manual folding or manual bubble removal is required, which reduces the labor intensity of the staff, and can smoothly fit the protective paper inside the solar back panel, thereby improving the yield rate.

Four screw rods 23 are rotatably provided on the base plate 1 and are respectively connected to the working rods of the four servo motors 22 in the axial direction. Two light rods 2 are provided between the support frames 21 on both sides of each screw rod 23 and the base plate 1. A bracket 24 sleeved on the screw rod 23 is slidably provided on the two light rods 2 on the same side of the base plate 1. The bracket 24 and the base plate 1 are parallel to each other. A connecting rod 25 is rotatably provided on the four brackets 24. The four connecting rods 25 are connected to the base plate 1. The ends of the connecting rod 25 are rotatably connected to the four blades 11, so that each blade 11 can rotate up and down independently; in order not to affect the incision on the cutting protection paper, a left-right moving device 5 is provided on the support frame 21, and the left-right moving device 5 is slidably provided with a front-back moving device 6, and the front-back moving device 6 is slidably provided with a moving block 61, and the end of the moving block 61 is provided with a second cylinder 62, and the working rod of the second cylinder 62 is provided with a laser cutting head 63, and the laser cutting head 63 can automatically cut the incision on the protection paper, and no special restrictions are made here, and they also belong to the protection scope of the present invention.
