Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a testing mechanism for solar cell welding fixtures. 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] The existing welding fixtures are all in a horizontal position during inspection, which results in the equipment occupying a large space. Utility Model Content

[0031] Example

[0032] Please see Figures 1 to 5 As shown, this embodiment provides a battery cell welding fixture inspection mechanism, which includes a frame 10, a conveying assembly 20, an inspection assembly 30, and an ejection assembly 40. The frame 10 has a feed inlet on its first side and a discharge outlet on its second side. The conveying assembly 20 is disposed inside the frame 10 and is connected to the feed inlet and discharge outlet. The conveying assembly 20 is configured to reciprocate the welding fixture in the vertical direction within the frame 10. The inspection assembly 30 includes a first inspection element 31, a second inspection element 32, and a third inspection element 33. The first inspection element 31 is disposed on the inner wall of the first side of the frame 10, the second inspection element 32 is disposed on the conveying assembly 20, and the third inspection element 33 is disposed at the top center of the inside of the frame 10. The ejection assembly 40 is disposed at the top of the frame 10 and is configured to eject any damaged welding fixtures detected by the inspection assembly 30 from the conveying channel of the conveying assembly 20.

[0033] As can be seen, by vertically setting the transport components inside the frame 10, together with the inspection components 30 and the ejection components 40, the welding fixtures can be transported and inspected simultaneously, while utilizing the upper space and reducing the equipment's footprint.

[0034] In one embodiment, the conveying assembly 20 includes a mounting frame 21, a drive component 22, a first sprocket 23, a second sprocket 24, a transmission chain 25, and multiple transport stations 26. The mounting frame 21 is vertically mounted inside the frame 10. The drive component 22 is located at the bottom of the mounting frame 21, and the drive end of the drive component 22 is connected to the first sprocket 23. The second sprocket 24 is rotatably mounted on the top of the mounting frame 21. The transmission chain 25 is sleeved on the first sprocket 23 and the second sprocket 24. The multiple transport stations 26 are equidistantly arranged on the transmission chain 25. The transport stations 26 are configured to receive welding fixtures at the feed inlet and transport the welding fixtures after inspection to the discharge outlet.

[0035] Specifically, the transport station includes a first mounting plate 260 and multiple first rollers 261. The first mounting plate 260 is mounted on the transmission chain 25, and the multiple first rollers 261 are equidistantly arranged on the first mounting plate 260. Both the inlet and outlet are provided with a bearing station 11. The bearing station 11 includes a second mounting plate 110 and multiple second rollers 111. The second mounting plate 110 is fixedly mounted on the inlet and outlet, and the multiple second rollers 111 are equidistantly arranged on the second mounting plate 110. The transport station and the bearing station can transport materials alternately.

[0036] As can be seen, the vertical transportation of the welding fixture is achieved through the cooperation of the mounting frame 21, the drive component 22, the first sprocket 23, the second sprocket 24, the transmission chain 25 and the multiple transport stations 26. The structure is simple and easy to maintain.

[0037] In one implementation, a pressure sensor 27 is provided on the transport station 26, and the pressure sensor 27 is configured to detect whether there is welding fixture on the transport station 26.

[0038] As can be seen, the pressure sensor 27 detects whether there is welding fixture on the transport station 26. The structure is simple and easy to maintain.

[0039] In one implementation, the first detection element 31 is spaced above the feed inlet. The first detection element 31 is an infrared thermal imager. The second detection element 32 is mounted on the mounting bracket 21 and is corresponding to the first detection element 31. The second detection element 32 is also an infrared thermal imager. The first detection element 31 and the second detection element 32 are configured to perform damage detection on the two clamping surfaces of the welding fixture on the transport station 26.

[0040] Specifically, the third inspection component 33 is an industrial camera 330 and a vision inspection device 331. The vision inspection device 331 is located at the top center inside the frame 10, and the industrial camera 330 is located below the vision inspection device 331. The industrial camera 330 is configured to perform damage detection on the clamping part of the welding fixture on the lower conveying assembly 20.

[0041] It can be seen that by symmetrically setting the first inspection piece 31 and the second inspection piece 32 at the same height to inspect the clamping surfaces on both sides of the welding fixture, the inspection efficiency is improved. At the same time, by inspecting at the transport station 26 below the third inspection piece 33, the damaged welding fixture is pushed out of the transport station 26. One piece serves multiple purposes, improving efficiency and reducing costs.

[0042] In one embodiment, the ejection assembly 40 includes a cylinder 41 and a moving member 42. The cylinder 41 is disposed on the top of the frame 10, and the moving member 42 is connected to the drive end of the frame 10.

[0043] As can be seen, the ejector component 40 has a simple structure and is easy to use and maintain.

[0044] In one implementation, the battery cell welding fixture inspection mechanism also includes a replenishment assembly 50, which is disposed on the outside of the frame 10 and is configured to push intact welding fixtures into the conveying assembly 20 to replace damaged welding fixtures.

[0045] Specifically, the replenishment component 50 includes a transport component 51, an ejector component 52, a fourth detection component 53, and an alarm component 54. The transport component 51 is located on one side of the frame 10, and its discharge end is connected to the discharge end of the conveying component 20. The ejector component 52 is located at the discharge end of the transport component 51 and is configured to push the welding fixture at the discharge end of the transport component 51 into the discharge end of the conveying component 20. The alarm component 54 is located at the feed end of the transport component 51. The fourth detection component 53 is located in the middle of the transport component 51 and is electrically connected to the alarm component 54. The fourth detection component 53 is configured to detect whether there is an intact welding fixture on the transport component 51, and the alarm component 54 is configured to remind personnel to replenish the intact welding fixture.

[0046] It can be seen that by setting up the replenishment component 50, in conjunction with the pressure sensor 27 on the transport station 26, the missing transport station 26 can be automatically replenished with intact welding fixtures, saving manpower.

[0047] The working principle of the above-mentioned battery cell welding fixture inspection mechanism is as follows:

[0048] The welding fixture to be inspected / used enters the conveying assembly 20 from the feed port. The conveying assembly 20 raises the welding fixture to be inspected / used to the height of the first inspection piece 31 and the second inspection piece 32. The first inspection piece 31 and the second inspection piece 32 inspect the clamping surfaces on both sides of the welding fixture to be inspected / used, and mark any damaged welding fixtures. After inspection, the welding fixture continues to rise to below the third inspection piece 33. The third inspection piece 33 takes a picture of the clamping part of the welding fixture and marks any damaged welding fixtures. The ejector assembly 40 pushes the damaged welding fixture out of the transport channel of the transport assembly. At this time, the pressure sensor 27 on the transport station 26 detects that there is no welding fixture on the station. The transport component 51 transports the intact welding fixture to the preparation station before the ejector 52. The ejector 52 pushes the intact welding fixture into the transport station 26 where there is no welding fixture. When the fourth inspection piece 53 detects that there is no welding fixture on the transport component 51, it triggers the alarm 54 to remind personnel to replenish the intact welding fixture.
