Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel processing, specifically a welding strip coating device for photovoltaic panel processing. Background Technology

[0002] Solder ribbon is a welding material used on photovoltaic modules. Its main function is to connect and conduct electricity. Solder ribbon is an important raw material in the photovoltaic module welding process. Some parts of the photovoltaic solder ribbon need to be welded to each other, while other parts do not need to be welded. The parts that do not need to be welded need to be insulated from other photovoltaic solder ribbons or the base plate of the solar panel. Therefore, a coating operation is required on the surface of the solder ribbon.

[0003] In the prior art, the welding strip and the coating are usually guided into the coating box by guide wheels for heating and coating. However, before coating, due to the lack of an effective cleaning mechanism, the stains and burrs attached to the surface of the welding strip will lead to poor coating effect. Therefore, this utility model provides a welding strip coating device for photovoltaic panel processing. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a welding strip coating device for photovoltaic panel processing, including a support frame, a servo motor fixedly connected to the lower surface of the support frame, a rotating block fixedly provided at the output end of the servo motor, a connecting rod rotatably connected to the inner wall of the rotating block, a connecting column rotatably connected to the inner wall of the connecting rod, a slider fixedly connected to the lower surface of the connecting column, the slider being connected to the support frame, a limit plate fixedly connected to the lower surface of the slider, a fixing block fixedly connected to the outer wall of the limit plate, a brush slidably connected to the upper surface of the fixing block, a screw threadedly connected to the inner wall of the brush, and the screw being connected to the fixing block.

[0006] Preferably, a base plate is fixedly connected to the lower surface of the first bracket, a chip collection box is provided on the upper surface of the base plate, a negative pressure machine is provided inside the chip collection box, and a fine barrier net is provided inside the chip collection box.

[0007] Preferably, a housing is fixedly connected to the upper surface of the base plate, a bearing frame is fixedly connected to the outer wall of the housing, a bidirectional lead screw is rotatably connected to the inner wall of the bearing frame, a moving block is threadedly connected to the outer wall of the bidirectional lead screw, the outer wall of the moving block is slidably connected to the inner wall of the bearing frame, and a pressing roller is rotatably connected to the outer wall of the moving block. A limit post is fixedly connected to the inner wall of the bearing frame on the other side, and the outer wall of the limit post is slidably connected to the inner wall of the bracket on the other side.

[0008] Preferably, a material rack is fixedly connected to the upper surface of the base plate, a support bracket is fixedly connected to the upper surface of the base plate, a guide wheel is rotatably connected to the outer wall of the support bracket, and a winding roller is provided on the upper surface of the base plate.

[0009] Preferably, a heating telescopic rod is fixedly connected to the inner top wall of the outer shell, a heating plate is fixedly connected to the outer wall of the heating telescopic rod, the interior of the outer shell is located outside the second bracket, a fan is fixedly connected to the upper surface of the outer shell, a pipe is fixedly connected to the outer wall of the fan, and the pipe is connected to the outer shell.

[0010] Preferably, a brush plate is fixedly connected to the outer wall of the housing.

[0011] Preferably, the brush head is a soft brush with the bristle tips ground and rounded, and the guide wheel and the extrusion roller are both made of silicone rubber.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The photovoltaic panel processing welding strip coating device of this utility model starts a servo motor to drive the rotating block, which causes the connecting rod to move the connecting column. The connecting column can drive the slider to slide on the inner wall of the bracket. At the same time, the slider can drive the limiting plate to move. Brushes of different widths are fixed to the limiting plate by screws. In this way, the position of the welding strip can be restricted, and it can also be used to clean welding strips of different widths. This solves the problem that the lack of an effective cleaning mechanism causes the stains and burrs on the surface of the welding strip to cause poor coating effect.

[0014] 2. The photovoltaic panel processing welding strip coating device of this utility model, by rotating the handle on the bidirectional screw, causes the moving blocks to move towards each other. The moving blocks can drive the extrusion roller to make the moving block on the other side slide on the outer wall of the limiting column. The set bearing frame can restrict the movement of the moving blocks. Through the above structure, the effect of coating welding strips of different thicknesses can be achieved.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-5 This utility model provides a welding strip coating device for photovoltaic panel processing, including a bracket 1. All electrical appliances used in this utility model are commercially available, and their specific structures and working principles are existing technologies well known to those skilled in the art, and therefore will not be described further here. A servo motor 2 is fixedly connected to the lower surface of the bracket 1. A rotating block 3 is fixedly installed at the output end of the servo motor 2. A connecting rod 4 is rotatably connected to the inner wall of the rotating block 3. A connecting column 5 is rotatably connected to the inner wall of the connecting rod 4. A slider 6 is fixedly connected to the lower surface of the connecting column 5. The slider 6 is connected to the bracket 1. A limit plate 7 is fixedly connected to the lower surface of the slider 6. A fixing block is fixedly connected to the outer wall of the limit plate 7. 8. A brush 9 is slidably connected to the upper surface of the fixed block 8. A screw 10 is threadedly connected to the inner wall of the brush 9. The screw 10 is connected to the fixed block 8. According to the width of the welding strip to be coated, the servo motor 2 fixed on the bracket 1 is started to make the rotating block 3 rotate. The rotating block 3 can drive the connecting rod 4 to make the connecting column 5 drive the slider 6 to slide on the inner wall of the bracket 1. Thus, the two limiting plates 7 fixed on the lower surface of the slider 6 can adjust the distance between them. According to the spacing, two brushes 9 of the required width are installed on the limiting plate 7 using the screw 10. This can achieve the effect of limiting the movement trajectory of the welding strip while also cleaning the upper and lower surfaces of welding strips of different widths.

[0025] like Figures 1 to 5 As shown, a base plate 11 is fixedly connected to the lower surface of the bracket 1, and a chip collection box 12 is provided on the upper surface of the base plate 11. A negative pressure machine is installed inside the chip collection box 12, and a fine mesh is installed inside the chip collection box 12. The chip collection box 12 is also installed above the base plate 11, which can collect the burrs and dust cleaned by the brush 9 through the negative pressure machine and filter them on the fine mesh. This can prevent the debris under cleaning from affecting the coating operation. Since the negative pressure machine and the fine mesh are existing technologies, they will not be shown in detail here.

[0026] like Figures 1 to 4 As shown, a housing 13 is fixedly connected to the upper surface of the base plate 11. A bearing frame 14 is fixedly connected to the outer wall of the housing 13. A bidirectional lead screw 15 is rotatably connected to the inner wall of the bearing frame 14. A moving block 16 is threadedly connected to the outer wall of the bidirectional lead screw 15. The outer wall of the moving block 16 is slidably connected to the inner wall of the bearing frame 14. An extrusion roller 17 is rotatably connected to the outer wall of the moving block 16. A limit post 18 is fixedly connected to the inner wall of the bearing frame 14 on the other side. The outer wall of the limit post 18 is slidably connected to the inner wall of the bracket 1 on the other side. According to the thickness of the welding strip, the handle on the bidirectional lead screw 15 is rotated to make it rotate on the inner wall of the bearing frame 14. The rotation of the bearing frame 14 can adjust the moving blocks 16 on the upper and lower sides to move towards each other, thereby adjusting the distance between the two extrusion rollers 17 to achieve the effect of welding strips of different thicknesses.

[0027] like Figure 1 and Figure 5 As shown, a material rack 19 is fixedly connected to the upper surface of the base plate 11, a material rack 20 is fixedly connected to the upper surface of the base plate 11, and a support 21 is fixedly connected to the upper surface of the base plate 11. A guide wheel 22 is rotatably connected to the outer wall of the support 21. A take-up roller 27 is provided on the upper surface of the base plate 11. A material roller containing welding strips to be coated is placed on the material rack 19. The guide wheel 22 on the support 21 can guide the coating on the coating roll on the material rack 20 to the middle of the two extrusion rollers 17. The take-up roller 27 provides space for take-up.

[0028] like Figures 1 to 5 As shown, a heating telescopic rod 23 is fixedly connected to the inner top wall of the outer casing 13, and a heating plate 24 is fixedly connected to the outer wall of the heating telescopic rod 23. The interior of the outer casing 13 is located outside the support 21. A fan 25 is fixedly connected to the upper surface of the outer casing 13, and a pipe 26 is fixedly connected to the outer wall of the fan 25. The pipe 26 is connected to the outer casing 13. The heating plate 24 can be heated, and the heating telescopic rod 23 fixed on it can move the heating plate 24 to an appropriate position. The coated welding strip is fed into the lower part of the pipe 26 for heat dissipation through the support 21 and guide wheel 22 inside, so that the welding strip on the take-up roller 27 can be wound up without being damaged by residual heat.

[0029] like Figure 1 and Figure 5 As shown, a brush plate 28 is fixedly connected to the outer wall of the housing 13. The brush plate 28 can clean the coated solder strip again to ensure that no other impurities will affect the winding process.

[0030] like Figure 1 and Figure 5 As shown, the brush head of the brush 9 is a soft brush with the tips of the bristles ground and rounded. The guide wheel 22 and the extrusion roller 17 are both made of silicone rubber. The brush head bristles are ground and rounded to prevent scratches from being left on the solder strip. The guide wheel 22 and the extrusion roller 17 made of silicone rubber also ensure that the surface of the solder strip will not be damaged.

[0031] During operation, based on the required width of the weld strip to be coated, the servo motor 2 fixed on the bracket 1 is activated to rotate the rotating block 3. The rotating block 3 drives the connecting rod 4, which in turn drives the connecting column 5 to slide the slider 6 against the inner wall of the bracket 1. This allows the two limiting plates 7 fixed to the lower surface of the slider 6 to adjust the distance between them. Depending on the spacing, two brushes 9 of the required width are installed on the limiting plates 7 using screws 10. This achieves both limiting the movement trajectory of the weld strip and cleaning the upper and lower surfaces of weld strips of different widths. Depending on the thickness of the weld strip, the handle on the bidirectional lead screw 15 is rotated to rotate against the inner wall of the support frame 14. The rotation of the support frame 14 adjusts the movement of the upper and lower moving blocks 16 towards each other, thereby adjusting the spacing between the two extrusion rollers 17 to accommodate weld strips of different thicknesses. During the coating operation, the weld strip to be coated is placed on the material rack 19. The material roller has a chip collection box 12 above the base plate 11. The chip collection box 12 can collect the burrs and dust cleaned by the brush 9 through the negative pressure machine and filter them on the fine mesh. This can prevent the debris from the cleaning process from affecting the coating operation. Since the negative pressure machine and fine mesh are existing technologies, they will not be shown in detail here. The guide wheel 22 on the bracket 21 can guide the coating roll on the material rack 20 to the middle of the two extrusion rollers 17. The heating plate 24 can heat the material. The heating telescopic rod 23 fixed on the heating plate 24 can move the heating plate 24 to the appropriate position. The coated welding strip is fed into the lower part of the pipe 26 for heat dissipation through the internal bracket 21 and guide wheel 22. This ensures that the welding strip is not damaged by residual heat when the take-up roller 27 is wound up. The brush plate 28 can clean the coated welding strip again to ensure that there are no other impurities affecting the winding.
