Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module manufacturing equipment, and more specifically, to a cleaning device for overflowing glue on the frame of a photovoltaic module assembly line. Background Art

[0002] With the development of science and technology, the application of photovoltaic modules is becoming more and more extensive. To avoid damage to photovoltaic modules during transportation, before leaving the factory, photovoltaic modules usually need to be connected and fixed to the metal frame by gluing around the laminate. The frame of the photovoltaic module can play roles such as sealing the module, increasing strength, and extending the service life. However, glue overflow is likely to occur during framing. If the overflowing glue is not cleaned, it will stick everywhere during the component conveying process, which is likely to cause secondary pollution to the components. Currently, the common glue removal methods are basically manual wiping of the overflowing glue by workers. This cleaning method has low efficiency and poor cleaning effect. Although the residual silicone is cleaned, it is extremely labor-consuming.

Optionally, the left mounting frame 09 and the right mounting frame 10 are symmetrically arranged on both sides along the conveying direction of the conveying assembly 07, and the bottom of the mounting frame 08 is fixedly connected to the bottom frame 03 in the base 02; the feeding shaft 28, the guiding assembly 17 and the winding shaft 26 are all fixed on the mounting frame 08. Along the direction from the bottom frame 03 to the conveying assembly 07, the feeding shaft 28, the guiding assembly 17 and the winding shaft 26 are located on a straight line, and the guiding assembly 17 is located between the feeding shaft 28 and the winding shaft 26.

The cleaning efficiency is high, the labor consumption is reduced, and the production rhythm is not affected.

[0055] Please continue to refer to Figures 1 to 7 , the embodiment of the present application provides a glue overflow cleaning device 100 for the frame of the photovoltaic module assembly line. The left mounting frame 09 / right mounting frame 10 includes a vertical frame 11, a cross bar 33 and an inclined bar 45. The vertical frame 11 is perpendicular to the plane where the conveying assembly 07 is located, and the vertical frame 11 is fixedly connected to the base 02;

[0056] The cross bar 33 includes an upper cross bar 12 and a lower cross bar 13. The upper cross bar 12 and the lower cross bar 13 are parallel to the plane where the conveying assembly 07 is located. Along the direction perpendicular to the plane where the conveying assembly 07 is located, the conveying assembly 07 is located between the upper cross bar 12 and the lower cross bar 13;

[0057] One end of the upper cross bar 12 is fixedly connected to the vertical frame 11, the other end of the upper cross bar 12 is fixedly connected to the feeding shaft 28, one end of the lower cross bar 13 is fixedly connected to the vertical frame 11, and the other end of the lower cross bar 13 is fixedly connected to the winding shaft 26;

[0058] The diagonal bar 45 includes an upper diagonal bar 14 and a lower diagonal bar 15. One end of the upper diagonal bar 14 is fixed to the upper cross bar 12, and the other end is fixed to the vertical frame 11. One end of the lower diagonal bar 15 is fixed to the lower cross bar 13, and the other end is fixed to the vertical frame 11.

[0059] The guiding component 17 is fixed to the fixing block 16 in the mounting frame 08.

[0060] Specifically, both the left mounting frame 09 and the right mounting frame 10 in the photovoltaic module production line edge glue overflow cleaning device 100 include a vertical frame 11, a cross bar 33, and a diagonal bar 45. The vertical frame 11 is fixedly connected to the bottom frame 03 in the base 02. The vertical frame 11 is perpendicular to the plane where the bottom frame 03 is located and perpendicular to the plane where the conveying component 07 is located. The cross bar 33 includes an upper cross bar 12 and a lower cross bar 13. Along the direction from the bottom frame 03 to the conveying component 07, the lower cross bar 13 is located below the conveying component 07, and the upper cross bar 12 is located above the conveying component 07. That is, the conveying component 07 is located between the upper cross bar 12 and the lower cross bar 13. The upper cross bar 12 and the lower cross bar 13 are parallel, and the upper cross bar 12 and the lower cross bar 13 are parallel to the plane where the conveying component 07 is located and parallel to the extending direction of the cross beam 05. One end of the upper cross bar 12 is fixed to the vertical frame 11, and the other end is fixed to the unwinding shaft 28. One end of the lower cross bar 13 is fixed to the vertical frame 11, and the other end is fixed to the winding shaft 26. The projection of the upper cross bar 12 on the plane where the bottom frame 03 is located overlaps with the projection of the lower cross bar 13 on the plane where the bottom frame 03 is located. The projection of the winding shaft 26 on the plane where the bottom frame 03 is located overlaps with the projection of the unwinding shaft 28 on the plane where the bottom frame 03 is located. Thus, the movement track of the cleaning strip 35 coincides with the unwinding track of the unwinding wheel 29 on the unwinding shaft 28 to the winding track of the winding wheel 27 on the winding shaft 26. When the unwinding wheel 29 on the unwinding shaft 28 and the winding wheel 27 on the winding shaft 26 rotate relative to each other, the cleaning strip 35 on the unwinding wheel 29 can be wound onto the winding wheel 27 on the winding shaft 26 after erasing the overflow glue. That is, the winding shaft 26 can wind the contaminated cleaning strip 35 onto the winding wheel 27 on the winding shaft 26 after the cleaning strip 35 erases the edge 01 of the photovoltaic module 00, completing the integration of cleaning and recycling.

[0061] The diagonal rod 45 includes an upper diagonal rod 14. The extending direction of the upper diagonal rod 14 intersects with the plane where the bottom frame 03 is located and is not perpendicular. One end of the upper diagonal rod 14 is fixed on the vertical frame 11, and the other end is fixed on the upper cross bar 12. That is, the upper cross bar 12, the vertical frame 11, and the upper diagonal rod 14 form a triangle, which can make the connection between the upper cross bar 12 and the vertical frame 11 more stable. The diagonal rod 45 also includes a lower diagonal rod 15. The extending direction of the lower diagonal rod 15 intersects with the plane where the bottom frame 03 is located and is not perpendicular. One end of the lower diagonal rod 15 is fixed on the vertical frame 11, and the other end is fixed on the lower cross bar 13. That is, the lower cross bar 13, the vertical frame 11, and the lower diagonal rod 15 form a triangle, which can make the connection between the lower cross bar 13 and the vertical frame 11 more stable. Further, the guiding component 17 is fixed on the fixing block 16 on the mounting frame 08. That is, in the direction from the bottom frame 03 to the conveying component 07, the guiding component 17 is located between the upper diagonal rod 14 and the lower diagonal rod 15. Further, in the direction from the bottom frame 03 to the conveying component 07, the guiding component 17 is located between the unwinding shaft 28 connected to the upper cross bar 12 and the winding shaft 26 connected to the lower cross bar 13. The guiding component 17 can guide the cleaning strip 35. In the direction from the cross bar 33 to the photovoltaic module 00, the guiding component 17 can make the cleaning strip 35 approach or move away from the frame 01 of the photovoltaic module 00. When the cleaning strip 35 approaches and contacts the frame 01 of the photovoltaic module 00, due to the conveyance of the photovoltaic module 00 on the conveying component 07, a relative displacement occurs between the photovoltaic module 00 and the cleaning strip 35, and the cleaning strip 35 can remove the overflow glue on the frame 01 of the photovoltaic module 00 through friction. Thus, through the design of the installation positions among the cross bar 33, the vertical frame 11, and the diagonal rod 45, the projection of the unwinding shaft 28 on the plane where the bottom frame 03 is located can overlap with the projection of the winding shaft 26 on the plane where the bottom frame 03 is located. The cleaning strip 35 can be unwound or wound through the relative rotation of the unwinding shaft 28 and the winding shaft 26. The guiding component 17 can control the cleaning strip 35 to approach or move away from the photovoltaic module 00. When approaching, the cleaning strip 35 can wipe off the overflow glue on the frame 01 of the photovoltaic module 00, and when moving away, it will not interfere with the conveyance of the photovoltaic module 00 on the conveying component 07. That is, the overflow glue is cleaned on the photovoltaic module production line without affecting the production rhythm, and at the same time, the contaminated cleaning strip 35 after cleaning the overflow glue can be recycled without increasing the environmental burden.

[0062] Please continue to refer to Figures 1 to 7 , the embodiment of the present application provides a cleaning device 100 for the overflow glue on the frame of a photovoltaic module production line. The guiding component 17 includes an upper guiding part 18 and a lower guiding part 19. In the direction perpendicular to the plane where the conveying component 07 is located, the upper guiding part 18 is located above the conveying component 07, and the lower guiding part 19 is located below the conveying component 07;

[0063] The upper guide member 18 includes a guide wheel 24-1 and a support rod 22-1. The support rod 22-1 is fixedly connected to the fixed block 16. The guide wheel 24-1 is fixed to one end of the support rod 22-1 away from the fixed block 16. The lower guide member 19 includes a guide wheel 24-2 and a support rod 22-2. The support rod 22-2 is fixedly connected to the fixed block 16. The guide wheel 24-2 is fixed to one end of the support rod 22-2 away from the fixed block 16.

[0064] Specifically, the guiding assembly 17 includes an upper guiding member 18. Along the direction from the bottom frame 03 to the conveying assembly 07, the upper guiding member 18 is located above the conveying assembly 07. The guiding assembly 17 further includes a lower guiding member 19. Along the direction from the bottom frame 03 to the conveying assembly 07, the lower guiding member 19 is located below the conveying assembly 07. That is, along the direction perpendicular to the plane where the conveying assembly 07 is located, the conveying assembly 07 is located between the upper guiding member 18 and the lower guiding member 19. Further, the projection of the upper guiding member 18 on the plane of the bottom frame 03 overlaps with the projection of the lower guiding member 19 on the plane of the bottom frame 03. The relaxation and tension of the cleaning strip 35 can be controlled by adjusting the size of the included angle α between the upper guiding member 18 and the lower guiding member 19. The upper guiding member 18 includes a guide wheel 24-1 and a support rod 22-1. One end of the support rod 22-1 is connected to the fixed block 16 and the other end is connected to the guide wheel 24-1. The lower guiding member 19 includes a guide wheel 24-2 and a support rod 22-2. One end of the support rod 22-2 is connected to the fixed block 16 and the other end is connected to the guide wheel 24-2. When the cleaning strip 35 is tensioned, the guide wheel 24-1 in the upper guiding member 18 and the guide wheel 24-2 in the lower guiding member 19 are in contact with the cleaning strip 35, and the cleaning strip 35 is in contact with the frame 01 of the photovoltaic module 00. When the cleaning strip 35 is relaxed, the guide wheel 24-1 in the upper guiding member 18 and the guide wheel 24-2 in the lower guiding member 19 are away from the cleaning strip 35, and the cleaning strip 35 is away from the frame 01 of the photovoltaic module 00. Thus, by arranging the upper guiding member 18 and the lower guiding member 19 on the upper and lower sides of the conveying assembly, the relaxation and tension of the cleaning strip 35 can be controlled by the included angle α between the upper guiding member 18 and the lower guiding member 19. The design of the guide wheel 24 can reduce the friction between the guiding assembly 17 and the cleaning strip 35 and reduce the loss of the cleaning strip 35 caused by friction.

[0065] Please continue to refer to Figures 1 to 7 Moreover, an edge glue overflow cleaning device 100 for a photovoltaic module production line according to an embodiment of the present application is provided. The guiding assembly 17 further includes a guide wheel driving shaft 30, a guide wheel driven shaft 20, a first gear 31, and a second gear 21. The lower guiding member 19 is fixedly connected to the guide wheel driving shaft 30. The upper guiding member 18 is fixedly connected to the guide wheel driven shaft 20. The guide wheel driving shaft 30 passes through the first gear 31 and is fixedly connected to the fixed block 16. The guide wheel driven shaft 20 passes through the second gear 21 and is fixedly connected to the fixed block 16. The first gear 31 meshes with the second gear 21.

[0066] Specifically, the guiding assembly 17 further includes a guide wheel drive shaft 30 and a first gear 31. One end of the guide wheel drive shaft 30 is connected to the support rod 22-2 in the lower guiding member 19 through a fastener. The other end of the guide wheel drive shaft 30 passes through the first gear 31 and is fixedly connected to the fixed block 16. The rotation of the guide wheel drive shaft 30 drives the lower guiding member 19 to move along a plane perpendicular to the plane where the conveying assembly 07 is located with the support rod 22-2 as the radius. The guiding assembly 17 further includes a guide wheel driven shaft 20 and a second gear 21. One end of the guide wheel driven shaft 20 is connected to the support rod 22-1 in the upper guiding member 18 through a fastener. The other end of the guide wheel driven shaft 20 passes through the second gear 21 and is fixed to the fixed block 16. The first gear 31 on the fixed block 16 meshes with the second gear 21. The rotation of the guide wheel drive shaft 30 drives the first gear 31 to rotate. Since the first gear 31 meshes with the second gear 21, the rotation of the first gear 31 drives the second gear 21 to rotate. The rotation of the second gear 21 drives the guide wheel driven shaft 20 to rotate. The rotation of the guide wheel driven shaft 20 drives the upper guiding member 18 to move along a plane perpendicular to the plane where the conveying assembly 07 is located with the support rod 22-1 as the radius. Thus, through the arrangement of the guide wheel drive shaft 30, the guide wheel driven shaft 20, the first gear 31 and the second gear 21, the number of drive motors can be reduced, and when the guide wheel drive shaft 30 rotates, the upper guiding member 18 and the lower guiding member 19 can be controlled to move synchronously in opposite directions through mechanical transmission, so as to control the relaxation and tension of the cleaning strip 35, and realize the removal of the overflow glue on the frame 01 of the photovoltaic module 00 by the cleaning strip 35.

[0067] Please continue to refer to Figures 1 to 7 , the embodiment of the present application provides a cleaning device 100 for the overflow glue on the frame of a photovoltaic module assembly line. The guide wheel drive shaft 30 is electrically connected to the cylinder 23, and the cylinder 23 is used to control the opening and closing of the guiding assembly 17.

[0068] Specifically, the guide wheel drive shaft 30 is electrically connected to the cylinder 23. In an alternative embodiment provided in the present application, when the cylinder 23 is activated, the guide wheel drive shaft 30 rotates in the clockwise direction. The guide wheel drive shaft 30 drives the lower guide member 19 to rotate in the clockwise direction with the support rod 22-2 as the radius. The rotation of the guide wheel drive shaft 30 drives the first gear 31 to rotate in the clockwise direction. Since the first gear 31 meshes with the second gear 21, the rotation of the first gear 31 drives the second gear 21 to rotate in the counterclockwise direction. The rotation of the second gear 21 drives the guide wheel driven shaft 20 to rotate in the counterclockwise direction. The rotation of the guide wheel driven shaft 20 drives the upper guide member 18 to rotate in the counterclockwise direction with the support rod 22-1 as the radius. That is, the upper guide member 18 rotates in the counterclockwise direction and approaches the frame 01 of the photovoltaic module 00 on the conveying assembly 07, and the lower guide member 19 rotates in the clockwise direction and approaches the frame 01 of the photovoltaic module 00 on the conveying assembly 07. At this time, the guide wheel 24-1 in the upper guide member 18 contacts the cleaning strip 35, and the guide wheel 24-2 in the lower guide member 19 contacts the cleaning strip 35. The cleaning strip 35 contacts the frame 01 of the photovoltaic module 00. The cleaning strip 35 is tensioned and contacts the frame 01 of the photovoltaic module 00. The photovoltaic module 00 moves on the conveying assembly 07, and the cleaning strip 35 wipes off the overflowing glue.

[0069] In another alternative embodiment provided in the present application, when the cylinder 23 is activated, after the cleaning strip 35 wipes off the overflowing glue, the guide wheel drive shaft 30 rotates in the counterclockwise direction. The guide wheel drive shaft 30 drives the lower guide member 19 to rotate in the counterclockwise direction with the support rod 22-2 as the radius. The rotation of the guide wheel drive shaft 30 drives the first gear 31 to rotate in the counterclockwise direction. Since the first gear 31 meshes with the second gear 21, the rotation of the first gear 31 drives the second gear 21 to rotate in the clockwise direction. The rotation of the second gear 21 drives the guide wheel driven shaft 20 to rotate in the clockwise direction. The rotation of the guide wheel driven shaft 20 drives the upper guide member 18 to rotate in the clockwise direction with the support rod 22-1 as the radius. That is, the upper guide member 18 rotates in the clockwise direction and moves away from the frame 01 of the photovoltaic module 00 on the conveying assembly 07, and the lower guide member 19 rotates in the counterclockwise direction and moves away from the frame 01 of the photovoltaic module 00 on the conveying assembly 07. At this time, the guide wheel 24-1 in the upper guide member 18 does not contact the cleaning strip 35, and the guide wheel 24-2 in the lower guide member 19 does not contact the cleaning strip 35. The cleaning strip 35 does not contact the frame 01 of the photovoltaic module 00. The cleaning strip 35 relaxes and leaves the frame 01 of the photovoltaic module 00. The photovoltaic module 00 continues to be conveyed to the next process on the conveying assembly 07.

[0070] In this way, through the electrical connection between the idler wheel drive shaft 30 and the cylinder 23, the cylinder 23 controls the clockwise or counterclockwise rotation of the idler wheel drive shaft 30, so that the upper guide member 18 and the lower guide member 19 can be opened or closed through mechanical transmission. By opening or closing the guide assembly 17, the cleaning strip 35 is brought into contact with or away from the frame 01 of the photovoltaic module 00, thereby realizing the wiping of the overflow glue on the frame 01 and the continuous transfer of the photovoltaic module 00 after the overflow glue is wiped off.

[0071] Please continue to refer to Figures 1 to 7 , an overflow glue cleaning device 100 for the frame of a photovoltaic module assembly line is provided in an embodiment of the present application. When the guide assembly 17 is opened, the included angle α between the upper guide member 18 and the lower guide member 19 is greater than 90°. The upper guide member 18 and the lower guide member 19 do not contact the cleaning strip 35, and the cleaning strip 35 does not contact the photovoltaic module 00.

[0072] Specifically, when the guide assembly 17 is opened, the upper guide member 18 rotates away from the transfer assembly 07 in a direction perpendicular to the plane where the transfer assembly 07 is located with the support rod 22-1 as the radius, and the lower guide member 19 rotates away from the transfer assembly 07 in a direction perpendicular to the plane where the transfer assembly 07 is located with the support rod 22-2 as the radius. At this time, the distance between the upper guide member 18 and the lower guide member 19 is greater than the distance between the upper guide member 18 and the lower guide member 19 when the guide assembly 17 is closed, and the included angle α between the upper guide member 18 and the lower guide member 19 is greater than 90°. Specifically, when the guide assembly 17 is opened, the included angle α between the upper guide member 18 and the lower guide member 19 can be 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, etc. When the included angle α between the upper guide member 18 and the lower guide member 19 is greater than 90°, the guide wheel 24-1 in the upper guide member 18 does not abut against the cleaning strip 35, the guide wheel 24-2 in the lower guide member 19 does not abut against the cleaning strip 35, and the cleaning strip 35 does not abut against the frame 01 of the photovoltaic module 00. In this way, when the included angle α between the upper guide member 18 and the lower guide member 19 is greater than 90°, the guide assembly 17 is opened, and the photovoltaic module 00 can pass through the cleaning strip 35 in the left mounting frame 09 and the cleaning strip 35 in the right mounting frame 10 and continue to flow to the next process.

[0073] Please continue to refer to Figures 1 to 7 , an overflow glue cleaning device 100 for the frame of a photovoltaic module assembly line is provided in an embodiment of the present application. When the guide assembly 17 is closed, the included angle α between the upper guide member 18 and the lower guide member 19 is less than 90°. The guide wheel 24-1 of the upper guide member 18 and the guide wheel 24-2 of the lower guide member 19 abut against the side of the cleaning strip 35 facing away from the photovoltaic module 00, and the side of the cleaning strip 35 facing the photovoltaic module 00 abuts against the side of the frame 01 of the photovoltaic module 00.

[0074] Specifically, when the guiding assembly 17 is retracted, the upper guiding member 18 rotates close to the conveying assembly 07 in a direction perpendicular to the plane where the conveying assembly 07 is located with the support rod 22-1 as the radius, and the lower guiding member 19 rotates close to the conveying assembly 07 in a direction perpendicular to the plane where the conveying assembly 07 is located with the support rod 22-2 as the radius. At this time, the distance between the upper guiding member 18 and the lower guiding member 19 is less than the distance between the upper guiding member 18 and the lower guiding member 19 when the guiding assembly 17 is expanded, and the included angle α between the upper guiding member 18 and the lower guiding member 19 is less than 90°. Specifically, when the guiding assembly 17 is retracted, the included angle α between the upper guiding member 18 and the lower guiding member 19 can be 85°, 80°, 75°, 70°, 65°, 60°, 55°, 50°, etc. When the included angle α between the upper guiding member 18 and the lower guiding member 19 is less than 90°, the guiding wheel 24-1 in the upper guiding member 18 abuts against the cleaning strip 35, and the guiding wheel 24-2 in the lower guiding member 19 abuts against the cleaning strip 35. The other side of the cleaning strip 35 that does not abut against the guiding wheel 24-1 of the upper guiding member 18 and the guiding wheel 24-2 of the lower guiding member 19 abuts against the frame 01 of the photovoltaic module 00. Thus, when the included angle α between the upper guiding member 18 and the lower guiding member 19 is less than 90°, the guiding assembly 17 is retracted, and the cleaning strips 35 on both sides abut against both sides of the frame 01 of the photovoltaic module 00. The friction between the photovoltaic module 00 and the cleaning strips 35 on both sides during the conveyance of the photovoltaic module 00 on the conveying assembly 07 can cause the cleaning strips 35 to wipe off the overflow glue on the frame 01 of the photovoltaic module 00, with high cleaning efficiency and greatly reducing the labor cost.

[0075] Please continue to refer to Figures 1 to 7 , an overflow glue cleaning device 100 for the frame of a photovoltaic module assembly line is provided in an embodiment of the present application. A fixed stopper 32 is provided at one end of the unwinding shaft 28 away from the mounting bracket 08, and a fixed stopper 32 is provided at one end of the winding shaft 26 away from the mounting bracket 08. The fixed stopper 32 is used to prevent the unwinding wheel 29 / the winding wheel 27 from falling off.

[0076] Specifically, one end of the unwinding shaft 28 is fixed to the neutral frame 11 of the mounting frame 08, and the other end is suspended with the unwinding wheel 29 sleeved thereon. When the unwinding shaft 28 rotates, the unwinding shaft 28 drives the unwinding wheel 29 to rotate. To prevent the unwinding wheel 29 from falling off during rotation, a fixed stop block 32 is installed at the end of the unwinding shaft 28 away from the vertical frame 11. The fixed stop block 32 can block the end of the unwinding wheel 29 facing away from the vertical frame 11 to prevent the unwinding wheel 29 from falling off the unwinding shaft 28; one end of the winding shaft 26 is fixed to the neutral frame 11 of the mounting frame 08, and the other end is suspended with the winding wheel 27 sleeved thereon. When the winding shaft 26 rotates, the winding shaft 26 drives the winding wheel 27 to rotate. To prevent the winding wheel 27 from falling off during rotation, a fixed stop block 32 is installed at the end of the winding shaft 26 away from the vertical frame 11. The fixed stop block 32 can block the end of the winding wheel 27 facing away from the vertical frame 11 to prevent the winding wheel 27 from falling off the unwinding shaft 28. Thus, by providing the fixed stop block 32 at the ends of the unwinding shaft 28 and the winding shaft 26 away from the vertical frame 11, the winding wheel 27 or the unwinding wheel 29 can be prevented from loosening during rotation, reducing potential safety hazards.

[0077] It should be noted that the shape of the fixed stop block 32 can be circular, square, diamond-shaped, etc. The present application does not make specific requirements on the appearance of the fixed stop block 32, as long as it can prevent the unwinding wheel 29 or the winding wheel 27 from falling off. In an optional embodiment provided by the present application, the fixed stop block 32 is detachable. First, the fixed stop block 32 is removed from the winding shaft 26 or the unwinding shaft 28, and after the unwinding wheel 29 is sleeved on the unwinding shaft 28 or the winding wheel 27 is sleeved on the winding shaft 26, it can be reinstalled.

[0078] Please continue to refer to Figures 1 to 7 , an edge overflow glue cleaning device 100 for a photovoltaic module production line is provided in an embodiment of the present application. The unwinding shaft 28 is connected to a control device 25, and the control device 25 is used to control the locking and loosening of the unwinding shaft 28.

[0079] Specifically, the unwinding shaft 28 is electrically connected to the control device 25. The control device 25 can be installed on the vertical frame 11. The control device 25 can be a component with a control function such as a cylinder or a magnetic switch. The control device 25 can control the locking and loosening of the unwinding shaft 28. When the cleaning strip 35 cleans the edge 01 of the photovoltaic module 00, the control device 25 locks the unwinding shaft 28, and in cooperation with the guiding assembly 17, it retracts, the cleaning strip 35 is tensioned, and the overflow glue on the side of the edge 01 of the photovoltaic module 00 is removed by friction. When the overflow glue on the edge 01 of a certain photovoltaic module 00 has been cleaned, the control device 25 loosens the unwinding shaft 28, the cleaning strip 35 is relaxed, and in cooperation with the guiding assembly 17, it opens, and the cleaning strip 35 moves away from the cleaned photovoltaic module 00. The conveying assembly 07 continues to convey the photovoltaic module 00 to the next process. Thus, by controlling the locking and loosening of the unwinding shaft 28 by the control device 25, the tensioning and relaxation of the cleaning strip 35 can be controlled, realizing the flexible switching between the cleaning strip 35 being tensioned to wipe off the overflow glue and the cleaning strip 35 being relaxed and moving away from the edge 01 of the photovoltaic module 00.

[0080] Please continue to refer to Figures 1 to 7 Figures 1 to 7 , Embodiments of the present application provide a cleaning device 100 for the overflow glue on the frame of a photovoltaic module assembly line. The material collecting shaft 26 is electrically connected to the motor 34, and the motor 34 controls the start and stop of the material collecting shaft 26.

[0081] Specifically, the material collecting shaft 26 is electrically connected to the motor 34. The motor 34 can be installed on the vertical frame 11. The motor 34 can be a component with a driving function such as a DC motor or an AC motor. The motor 34 can drive the material collecting shaft 26 to rotate. When the photovoltaic module 00 reaches in front of the left mounting frame 09 and the right mounting frame 10, the motor 34 drives the material collecting shaft 26 to rotate in the direction opposite to the winding direction of the cleaning strip 35, and the cleaning strip 35 is relaxed to ensure that there is enough space for the photovoltaic module 00 to enter between the two cleaning strips 35. When the cleaning strip 35 cleans the frame 01 of the photovoltaic module 00, the motor 34 drives the material collecting shaft 26 to rotate in the direction of winding the cleaning strip 35, and cooperates with the guiding component 17 to wind up. The cleaning strip 35 is tensioned to rub the side of the frame 01 of the photovoltaic module 00 to remove the overflow glue. When the overflow glue on the frame 01 of a certain photovoltaic module 00 is cleaned up, the motor 34 drives the material collecting shaft 26 to rotate in the direction of winding the cleaning strip 35, and winds up the cleaning strip 35 contaminated during the cleaning of the overflow glue onto the winding wheel 27 of the material collecting shaft 26. Cooperating with the guiding component 17 to open, the cleaning strip 35 moves away from the cleaned photovoltaic module 00. The conveying component 07 continues to convey the photovoltaic module 00 to the next process. In this way, through the drive of the motor 34 on the material collecting shaft 26, the tension and relaxation of the cleaning strip 35 can be controlled, realizing the flexible switching between the tensioned cleaning strip 35 for wiping the overflow glue and the relaxed cleaning strip 35 moving away from the frame 01 of the photovoltaic module 00.

[0082] In an alternative embodiment provided by the present application, the complete working steps of the photovoltaic module assembly line edge overflow glue cleaning device 100 for removing overflow glue are as follows: The photovoltaic module 00 is conveyed between the left mounting frame 09 and the right mounting frame 10. The alignment wheels on the conveying assembly 07 align the photovoltaic module 00. At this time, the control device 25 locks the unwinding shaft 28, and the motor 34 controls the winding shaft 26 to rotate in the opposite direction of winding the cleaning strip 35. The guiding assembly 17 opens, and the cleaning strip 35 relaxes; then the control device 25 controls the unwinding shaft 28 to remain locked, the motor 34 controls the winding shaft 26 to rotate in the direction of winding the cleaning strip 35, the guiding assembly 17 retracts, and the included angle α between the upper guiding member 18 and the lower guiding member 19 is less than 90°. The guiding wheel 24-1 of the upper guiding member 18 and the guiding wheel 24-2 of the lower guiding member 19 are in contact with the cleaning strip 35. At this time, the middle section of the cleaning strip 35 is tensioned and closely adheres to the edge frame 01 of the photovoltaic module 00. The photovoltaic module 00 continues to move forward on the conveying assembly 07. The frictional force generated between the tensioned cleaning strip 35 and the moving photovoltaic module 00 erases the overflow glue. After the erasing is completed, the guiding assembly 17 opens, the control device 25 controls the unwinding wheel 29 to relax, and the motor 34 drives the winding wheel 27 to rotate in the direction of winding the cleaning strip 35 to wind up the dirty cleaning strip 35, and the photovoltaic module 00 leaves this area and continues to flow to the next process. The above working steps continue to cycle to erase the overflow glue of the subsequent arriving photovoltaic modules 00; thus, through the continuous cycling of the above steps, continuous cleaning of the overflow glue on the photovoltaic module assembly line can be achieved, improving the cleaning efficiency and not affecting the production rhythm.

[0083] In summary, a photovoltaic module assembly line edge overflow glue cleaning device provided by the present utility model has at least achieved the following beneficial effects:

[0084] By setting an overflow glue cleaning device on the photovoltaic module assembly line, the edge overflow glue of the photovoltaic module can be cleaned without stopping the machine, with high cleaning efficiency and reduced manpower consumption.

[0085] Through the design of the installation positions among the cross bar, the vertical frame, and the inclined bar, the overflow glue can be cleaned on the photovoltaic module assembly line without affecting the production rhythm, and at the same time, the contaminated cleaning strip after cleaning the overflow glue can be recycled in time without increasing the environmental burden.

[0086] By controlling the included angle between the upper guiding member and the lower guiding member to relax and tension the cleaning strip, the design of the guiding wheel can reduce the friction between the guiding assembly and the cleaning strip and reduce the loss of the cleaning strip caused by friction.

[0087] Through the setting of the guide wheel driving shaft, the guide wheel driven shaft, the first gear, and the second gear, the number of driving motors can be reduced. By mechanical transmission, the upper guiding member and the lower guiding member are controlled to move synchronously in opposite directions to control the relaxation and tension of the cleaning strip, and the overflow glue on the edge of the photovoltaic module is removed by the cleaning strip.

[0088] Through the electrical connection between the guide wheel drive shaft and the cylinder, the cylinder controls the guide wheel drive shaft to rotate clockwise or counterclockwise, so that the upper guide and the lower guide can be opened or retracted through mechanical transmission, and the cleaning strip contacts or moves away from the frame of the photovoltaic module, thereby realizing the wiping of the glue overflow on the frame and the continuous transfer of the photovoltaic module after the glue overflow is wiped off.

[0089] When the included angle between the upper guide and the lower guide is greater than 90°, the guide assembly opens, and the photovoltaic module can pass through the cleaning strips in the left mounting frame and the cleaning strips in the right mounting frame and continue to flow to the next process; when the included angle between the upper guide and the lower guide is less than 90°, the guide assembly retracts, and the cleaning strip abuts against the frame of the photovoltaic module, and the glue overflow on the frame of the photovoltaic module can be wiped off by friction, with high cleaning efficiency and greatly reduced labor costs.

[0090] By arranging fixed stoppers at the ends of the unwinding shaft and the rewinding shaft far away from the vertical frame, the unwinding wheel or the rewinding wheel can be prevented from loosening during rotation, reducing potential safety hazards.

[0091] By controlling the locking and relaxation of the unwinding shaft by the control device, the tension and relaxation of the cleaning strip are controlled, realizing the flexible switching between the cleaning strip being tensioned to wipe off the glue overflow and the cleaning strip being relaxed and moving away from the frame of the photovoltaic module.

[0092] By driving the rewinding shaft by the motor, the tension and relaxation of the cleaning strip are controlled, realizing the flexible switching between the cleaning strip being tensioned to wipe off the glue overflow and the cleaning strip being relaxed and moving away from the frame of the photovoltaic module.
