Description

Technical Field

[0001] The present application relates to a polytetrafluoroethylene cloth and a lead wire assembly device. Background Art

[0002] like Figure 1 As shown, the PTFE cloth A is attached to the surface of the photovoltaic module, and the lead legs B in the photovoltaic module pass through the opening A1 of the PTFE cloth and open outward and fit with the upper surface of the PTFE cloth. The PTFE cloth A covers the outlet hole of the photovoltaic module, and the POE glue or EVA glue overflowing from the photovoltaic module during the lamination process will not overflow to the surface of the photovoltaic module. The opening width of the PTFE cloth is smaller than the thickness of the legs. The PTFE cloth is assembled to the lead of the photovoltaic module in a fully automated manner. Affected by positioning errors and machine vibrations, there is a possibility that the lead legs cannot pass through the opening of the PTFE cloth smoothly. If the lead legs cannot pass through the opening of the PTFE cloth, it is very likely that the top of the PTFE cloth will be deformed or cause itself to deform or break. Summary of the invention

[0013] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0014] Example

[0015] The photovoltaic modules are transported by conveyor belts or roller lines in the production line, and the photovoltaic modules are clamped and positioned in the corresponding process equipment. The assembly device in this embodiment is located above the photovoltaic modules and is driven to move by a two-axis or three-axis displacement platform set in the machine equipment. The polytetrafluoroethylene cloth and lead assembly device is generally fixed on the Z-axis module of the displacement platform, including a lead clamping mechanism 100, a polytetrafluoroethylene cloth fixing mechanism 200 and a guiding mechanism 300.

[0016] The lead wire clamping mechanism 100 comprises two clamping members, which clamp two legs of the lead wire respectively. Before the device is started, the lead wire legs are in a vertical state, and the clamping members clamp the legs to keep them in a vertical state.

[0017] The Teflon cloth fixing mechanism 200 includes a vacuum adsorption block 210 and a first power element 220. A suction part is provided at the bottom of the vacuum adsorption block, and the first power element 220 drives the vacuum adsorption block to rise and fall. The suction part is constructed in two ways. The first way is to provide a plurality of suction holes at the bottom of the vacuum adsorption block, and the second way is to provide a vacuum suction cup 230 at the bottom of the vacuum adsorption block. In addition, the Teflon cloth in the production line is recycled repeatedly, and the surface of the Teflon cloth is not completely flat. When the suction part adopts the first way, it may be impossible to firmly absorb the Teflon cloth. The vacuum suction cup can adaptively fine-tune the opening shape according to the Teflon cloth to ensure that the Teflon cloth can be tightly absorbed to prevent the Teflon cloth from falling off midway. The suction part in this embodiment is composed of two vacuum suction cups. The two vacuum suction cups are located at the two ends of the guide hole, respectively adsorbing the two ends of the Teflon cloth. The caliber of the vacuum suction cup is smaller than the width of the Teflon cloth. The Teflon cloth adsorbed by negative pressure may be distorted, affecting the insertion of the lead legs. See. Figure 4 In this embodiment, two protrusions 240 are arranged at the bottom of the vacuum adsorption block, respectively located on both sides of the vacuum suction cup. The protrusions are arranged along the long sides of the polytetrafluoroethylene cloth, and the long side edges of the polytetrafluoroethylene cloth are attached to the bottom plane of the protrusions to maintain a flat state.

[0018] The guide mechanism 300 includes two guide plates 310 and a second power element 320 . A guide hole is provided in the vacuum adsorption block. The second power element drives the guide plates 310 to rise and fall along the guide hole.

[0019] The following will be combined with the attached Figure 2 The structure of the device is described in detail.

[0020] The device includes a first base 410 and a second base 420, wherein the first base 410 is connected to the slide of the Z-axis module 500, the second base 420 is arranged below the Z-axis module, and the second base is fixedly connected to the first base, that is, the Z-axis module 500 drives the first base and the second base to rise and fall simultaneously. A vertical first guide rail 510 is arranged on the side of the first base 410, and a first slide plate 610 is slidably connected on the first guide rail, and the first power element 220 drives the first slide plate to rise and fall along the first guide rail. The first power element 220 is preferably a servo screw module, the body of the module is fixed on the first base 410, and the slide of the module is fixedly connected to the first slide plate. An L-shaped base plate 700 is arranged on the slide of the servo screw module, and the vacuum adsorption block 210 is connected to the L-shaped base plate. The second power element 320 is preferably a cylinder, the cylinder body is fixedly connected to the first base, and a connecting block 330 is arranged at the bottom of the telescopic rod, the top ends of the two guide plates are fixedly connected to the connecting block, and the bottom ends are inserted into the guide holes of the vacuum adsorption block. The bottom end of the guide piece is provided with a guiding inclined surface.

[0021] A second horizontal guide rail 520 is disposed at the bottom of the second base 420, a second slide plate 620 is slidably connected to the second guide rail, and a fifth power element 800 disposed on the second base drives the second slide plate to translate along the second guide rail. The lead clamping mechanism 100 is connected to the second slide plate.

[0022] In the actual production of photovoltaic modules, the shape of the lead legs is as follows Figure 3 As shown in the figure, the two lead legs are inwardly bent and need to be shaped into a vertical shape.

[0023] The clamping member includes an inner clamping block 110 and an outer clamping block 120; the lead clamping mechanism 100 includes a third power element 130 and a fourth power element 140, the third power element drives the two inner clamping blocks 110 to be relatively close to or relatively far away from each other, and the fourth power element drives the two outer clamping blocks 120 to move in a direction close to or away from the inner clamping blocks. The third power element and the fourth power element are fixedly connected to the second slide 620. The fifth power element 800 drives the clamping member to move in the direction of the lead legs, and the two closed inner clamping blocks 110 are inserted into the gaps of the lead legs. The third power element drives the two inner clamping blocks to open outward, and the Z-axis module drives the entire device upward, and the inner clamping block gradually moves upward to open the two lead legs. The fourth power element 140 drives the outer clamping block 120 to approach the inner clamping block, and the outer clamping block and the inner clamping block clamp the lead legs together. The third power element 130 is preferably a finger cylinder, and the two inner clamping blocks are connected to the two fingers of the finger cylinder; the fourth power element 140 is preferably a 180° open and close finger cylinder, and the two outer clamping blocks are connected to the two fingers of the finger cylinder.

[0024] The following is combined with Figure 5 To Attachment Figure 8 The workflow of the assembly device is described in detail.

[0025] See also Figure 5 The third power element 130 drives the two inner clamping blocks 110 to move horizontally and insert into the lower gap between the two lead legs. Figure 6 , the Z-axis module 500 drives the inner clamping block to move upward. During the upward movement, the third power element 130 drives the two inner clamping blocks 110 to open relative to each other, so that the two lead legs form a V-shaped structure. Figure 7 , the second power element 320 drives the guide piece 310 downward, so that the guide piece is inserted between the two lead legs; the third power element 130 drives the two inner clamping blocks 110 to approach, and the fourth power element 140 drives the outer clamping block 120 to rotate 90° to the side of the inner clamping block, and the outer clamping block 120 and the inner clamping block 110 clamp the two side surfaces of the lead legs respectively, and the inner side surface of the lead legs overlaps the guide slope of the guide piece 310. Figure 8The first power element 220 drives the vacuum adsorption block 210 downward, and the lead legs pass through the openings of the polytetrafluoroethylene cloth under the guidance of the guide plate. The fifth power element 800 drives the inner clamp block to withdraw from the gap between the lead legs; the first power element 220 drives the vacuum adsorption block to continue to move downward so that the polytetrafluoroethylene cloth contacts the upper surface of the photovoltaic module.

[0026] The guiding slope disposed at the bottom end of the guide piece 310 makes the bottom end portion of the guide piece thinner, thereby preventing the overlapping portion between the guide piece and the lead leg from being too thick.

[0027] like Figure 8 As shown, after the polytetrafluoroethylene cloth is installed on the lead legs, the lead legs are still in a vertical state. On this basis, the device can fully expand the lead legs outward to a horizontal state. The vacuum adsorption block 210 is connected to the substrate 700 through a guide rod and a spring 250. The polytetrafluoroethylene cloth is in flexible contact with the upper surface of the photovoltaic module, thereby preventing the surface of the photovoltaic module from being crushed.

[0028] See also Fig. 9 , the third power element 130 drives the two inner clamps to be inserted into the gap between the two lead legs again, and the fourth power element 140 drives the two inner clamps to open relative to each other again, so that the two lead legs form a larger V-shaped structure. Fig.10 The displacement platform of the equipment drives the device to move so that the protrusion comes to the top of the polytetrafluoroethylene cloth, and the first power element 220 drives the vacuum adsorption block to move downward again, and the protrusion presses the lead leg downward.

[0029] In summary, the assembly device disclosed in this embodiment has the dual functions of lead shaping and assembling polytetrafluoroethylene cloth. The lead legs can be accurately inserted into the openings of the polytetrafluoroethylene cloth under the guidance of the guide sheet, which greatly improves the efficiency of the automated assembly of polytetrafluoroethylene cloth and leads in the production line, and the assembly success rate is greater than 99%.
