Description
Technical Field
[0001] This utility model relates to the field of photovoltaic technology, and in particular to a screening device for a solar cell welding fixture. Background Technology
[0002] When solar cells and solder ribbons are laid out in strings, the solder ribbons between adjacent cells (also known as inter-string solder ribbons) are relatively long. If they enter the welding station without any control, the inter-string solder ribbons are prone to bending and deformation, which can easily lead to poor soldering at the solder joints on the solar cells adjacent to the inter-string solder ribbons. In addition, after the welded solar cells are split into strings by a string cutter, the remaining long solder ribbons will also warp, which is not conducive to subsequent layout and busbar welding.
[0003] Therefore, welding fixtures play a crucial role in the cell welding process. However, since most existing cell welding is done on automated production lines, problems with the welding fixtures can significantly impact the welding results. In the past, the inspection of welding fixtures was done manually, and by the time problems were discovered, the cells had already been mass-produced, resulting in huge losses for the company.
[0004] Therefore, a screening device for battery cell welding fixtures is needed to automatically inspect the welding fixtures and screen out damaged welding work to avoid production losses. Utility Model Content

[0028] Please see Figures 1 to 4As shown, this embodiment provides a screening device for battery cell welding fixtures, which includes a conveying assembly 10, a detection assembly 20, and a screening assembly 30. The conveying assembly 10 includes a mounting frame 11, a first driving member 12, and a transport member 13. The first driving member 12 is disposed on the top of the mounting frame 11, and the transport member 13 is disposed on the top of the mounting frame 11. The driving end of the first driving member 12 is connected to the transport member 13. Limiting strips 14 are symmetrically spaced on both sides of the transport member 13 along a first direction. The limiting strips 14 are configured to limit the welding fixtures on the transport member 13. The limiting strips 14 are provided with clearance grooves 15, and a screening station 16 is formed between the two clearance grooves 15. The detection assembly 20 includes a first detection element 21, a second detection element 22, and a third detection element 23. The first detection element 21 is provided with... At one end of the clearance groove 15 along the first direction, the second detection element 22 is spaced apart on the top of the screening station 16, and the third detection element 23 is located at the other end of the clearance groove 15 along the first direction. The screening assembly 30 includes a support frame 31, a second drive element 32, and a pusher element 33. The support frame 31 is located on one side of the screening station 16, and the top surface of the support frame 31 is flush with the top surface of the transport component 13. The second drive element 32 is located on the support frame 31, and the moving end of the second drive element 32 is connected to the pusher element 33. The pusher element 33 is located on the support frame 31 and can be moved back and forth along the second direction. The second drive element 32 is configured to drive the pusher element 33 to pass through the clearance groove 15 and push the damaged welding fixture on the transport component 13 out of the transport channel of the transport component 13. The first direction and the second direction are perpendicular to each other.
[0029] Specifically, the first direction is the length direction of the transport component 13.
[0030] Specifically, the first driving component 12 is an electric motor, and the second driving component 32 is a cylinder.
[0031] It can be seen that the cooperation of the conveying component 10, the detection component 20 and the screening component 30 realizes the automated detection and screening of welding fixtures, reducing production losses.
[0032] In one embodiment, the transport component 13 includes a drive wheel, a driven wheel, and a transport belt. The drive wheel is located at one end of the top of the mounting frame 11 and is connected to the drive end of the first drive component 12. The driven wheel is connected to the other end of the top of the mounting frame 11. The drive wheel and the driven wheel are connected by a transport belt. Multiple limit blocks 130 are arranged evenly on the transport belt. The limit blocks 130 are configured to limit and fix the bottom limit groove of the welding fixture.

[0034] In one embodiment, the first detection component 21 includes two first pressure sensors, which are respectively installed at the first end and the second end of the screening station 16 along the first direction. One end of each of the two first pressure sensors abuts against the clamping portions 50 on both sides of the welding fixture to detect the integrity of the clamping portions 50.
[0035] As can be seen, by setting the first detection component 21, the clamping part 50 of the welding fixture is detected, and welding fixtures with damage to the clamping part 50 are screened out.
[0036] In one embodiment, the third detection component 23 includes two second pressure sensors, which are respectively installed at the first end and the second end of the screening station 16 along the first direction. One end of each of the two second pressure sensors abuts against the clamping portions 50 on both sides of the welding fixture to detect the integrity of the clamping portions 50.
[0037] As can be seen, by setting the third inspection piece 23, the clamping part 50 of the welding fixture is inspected a second time, avoiding the situation where there is a missed inspection or the first inspection piece 21 is damaged and cannot be inspected.
[0038] In one embodiment, the second inspection component 22 includes a mounting bracket 220, an industrial camera 221, and a vision inspection device 222. The mounting bracket 220 is fixedly installed on the screening station 16, the vision inspection device 222 is located on the top of the mounting bracket 220, and the industrial camera 221 is located at the bottom of the vision inspection device 222 and is electrically connected to the vision inspection device 222.

The control system is configured to collect information and issue working instructions.
[0040] As can be seen, by setting the second inspection piece 22, the top of the welding fixture is inspected, and welding fixtures with damaged or missing parts at the top are screened out.
[0041] In one implementation, the pusher 33 is provided with two clearance grooves 15 at equal intervals. The distance between the two clearance grooves 15 is the same as the distance between two adjacent limit blocks 130, and the depth of the clearance grooves 15 is the same as the height of the limit blocks 130.
[0042] Specifically, the initial position of the pusher 33 is coaxial with the limit strip 14, and the inner wall of the pusher 33 is flush with the inner wall of the limit strip 14.
[0043] Specifically, a buffer pad, which is a rubber pad, is provided on the inner wall of the pusher 33.
[0044] It can be seen that by setting up the pusher 33, the damaged welding fixtures detected by the first inspection piece 21, the second inspection piece 22 and the third inspection piece 23 are pushed out of the transport channel to avoid production losses.
[0045] In one implementation, a receiving component 40 is provided on the other side of the screening station 16. The receiving component 40 includes a bearing plane 41, a third pressure sensor 42, and an alarm light 43. The bearing plane 41 is horizontally disposed on the other side of the screening station 16. The third pressure sensor 42 is disposed on the bearing plane 41. The alarm light 43 is disposed at the top of one side of the bearing plane 41. The third pressure sensor 42 is configured to detect whether there is a damaged welding fixture on the bearing plane 41. The alarm light 43 is configured to remind personnel that there is a damaged welding fixture on the bearing plane 41.
[0046] It is evident that by setting up the receiving component 40, real-time manual monitoring is avoided, saving manpower and resources.
