Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a bilateral correction mechanism. Background Technology

[0002] In the fabrication process of photovoltaic solar cells, adjacent cells are connected together using solder ribbons to form a cell string structure of a certain length. During the cell supply process, the cells need to be positioned, and their appearance and any defects such as microcracks need to be inspected.

[0003] Traditional positioning methods typically employ physical pushing or clamping for positioning. However, these methods require separate positioning of the long and wide sides of the solar cell, necessitating separate clamping or pushing drive mechanisms on both sides of the cell. This not only impacts the space occupied by the equipment but also hinders cost reduction. Summary of the Invention

[0004] The purpose of this invention is to propose a bilateral correction mechanism that can reduce space occupation and lower costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A double-sided alignment mechanism includes a frame, a base plate, an alignment module, and a cam drive assembly;

[0007] The pad is connected to the frame and is used to place the battery cells to be aligned;

[0008] The correction module includes two sets of elastic elements and two correction components that are slidably disposed perpendicularly on the frame. Each correction component has a correction part located on one side of the pad. The elastic elements are connected between the correction components and the frame and can extend and retract along the sliding direction of the correction components.

[0009] The cam drive assembly can push the two correction components to slide together relative to the frame, so that the two correction parts move together closer to or away from the pad.

[0010] Furthermore, the corrective section has one or more corrective ends arranged side by side at intervals, and the corrective ends are provided with an elastic structure; wherein, the elastic structure is preferably a spring sheet.

[0011] Furthermore, the corrective section has a U-shaped, Y-shaped, or H-shaped structure.

[0012] Furthermore, the cam drive assembly includes a vertical drive shaft, a cam coaxially connected to the drive shaft, and a drive member; the drive shaft is rotatably connected to the frame; the cam abuts against the two alignment members; and the drive member drives the drive shaft to rotate relative to the frame.

[0013] Furthermore, the cam includes a first cam and a second cam that are separately configured, the first cam abutting against one of the corrective components, and the second cam abutting against the other corrective component.

[0014] Furthermore, a roller is rotatably mounted on the corrective component, and the roller makes rolling contact with the cam.

[0015] Furthermore, the placement surface of the pad is provided with multiple grooves at intervals.

[0016] Furthermore, the pad is a transparent plate.

[0017] Furthermore, a light-emitting platform is provided below the pad.

[0018] Furthermore, the elastic element is a tension spring, and the two ends of the tension spring are respectively connected to fixed posts; the two fixed posts are respectively installed on the frame and the corresponding alignment component.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model discloses a double-sided alignment mechanism, which utilizes a cam drive assembly to drive two alignment components to overcome the elastic force of the elastic element and move synchronously in two mutually perpendicular directions, so that the alignment part moves away from the pad to free up enough space to place the battery cell on the pad; after the battery cell is placed on the pad, under the drive of the cam drive assembly and the elastic force of the elastic element, the alignment part moves toward the pad, thereby aligning and positioning the battery cell on the pad, saving space and reducing manufacturing costs.

[0021] 2. This utility model provides a double-sided alignment mechanism. By providing elastic structures at each alignment end of the alignment section to contact the battery cell, it can avoid hard contact with the battery cell, thereby reducing the risk of hard damage to the surface of the battery cell during the alignment process.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 6 As shown, a double-sided alignment mechanism includes a frame 1, a pad 2, an alignment module 3, and a cam drive assembly 4. The pad 2 is connected to the frame 1 and is used to hold the battery cells to be aligned. The alignment module 3 includes two sets of elastic members 33 and two alignment components 31 that are slidably disposed perpendicularly on the frame 1. Each alignment component 31 has an alignment portion 32 located on one side of the pad 2. The elastic members 33 are connected between the alignment components 31 and the frame 1 and are capable of extending and retracting along the sliding direction of the alignment components 31. The cam drive assembly 4 is used to push the two alignment components 31 to slide together relative to the frame 1, causing the two alignment portions 32 to move together closer to or further away from the pad 2.

[0030] Specifically, in this embodiment, the frame 1 includes a support plate 11 and a base plate 12 arranged vertically, and the support plate 11 and the base plate 12 are connected by a set of columns 13. The pad 2 is fixedly arranged above the support plate 11.

[0031] When visual inspection of the battery cells on the pad 2 is required, a camera can be set above the pad 2 and a light-emitting platform 5 can be set below the pad 2 to provide an illumination source.

[0032] In this embodiment, the placement surface of the pad 2 is slightly smaller than the size of the battery cell. This reduces the contact area between the pad 2 and the battery cell, and also prevents interference between the alignment component 31 and the pad 2 during the alignment process. The pad 2 can be made of a transparent plate with good wear resistance, such as acrylic or glass, to ensure light transmission.

[0033] Furthermore, such as Figure 2As shown, multiple grooves 21 are spaced apart on the placement surface of the pad 2 to further reduce the contact area between the pad 2 and the surface of the battery cell, thereby avoiding excessive contact friction and increasing the risk of microcracks in the battery cell. In addition, the grooves 21 can also enhance the scattering of light sources so that the bottom of the battery cell can have higher brightness transmitted through the battery cell.

[0034] In this embodiment, the corrective section 32 has one or a plurality of corrective ends 321 arranged side by side at intervals. Preferably, the corrective section 32 has a U-shaped, Y-shaped or H-shaped structure.

[0035] It should be noted that the corrective part 32 and the corrective component 31 can be an integral structure or a detachable and connectable separate structure.

[0036] Furthermore, the alignment end 321 is provided with an elastic structure 322, which is used to contact the side of the battery cell, so that when the alignment member 31 slides, the battery cell can be pushed by the elastic structure 322 to align the battery cell. Preferably, the elastic structure 322 is a spring sheet.

[0037] Preferred, such as Figure 5 As shown, the edge of the spring sheet adopts a curved surface design that is close to a plane, so as to ensure the elasticity of the spring sheet itself while making as much contact with the battery cell as possible, and also avoid the squeezing damage to the battery cell caused by hard contact.

[0038] In this embodiment, the elastic element 33 is preferably a tension spring, and the two ends of the tension spring are respectively connected to fixed posts 34; these two fixed posts 34 are respectively installed on the frame 1 and the corresponding correction component 31.

[0039] In this embodiment, the cam drive assembly 4 includes a vertical drive shaft 41, a cam 42 coaxially connected to the drive shaft 41, and a drive member 43. The drive shaft 41 is rotatably connected to the frame 1; the cam 42 abuts against two alignment members 31; and the drive member 43 drives the drive shaft 41 to rotate relative to the frame 1. Preferably, the drive member 43 is a motor.

[0040] Preferred, such as Figure 3 As shown, the cam 42 includes a first cam 421 and a second cam 422, which are separately configured. The first cam 421 abuts against one of the alignment components 31, and the second cam 422 abuts against the other alignment component 31. The first cam 421 and the second cam 422 can be made of an arc surface with a uniform diameter to increase the tolerance for assembly errors, or they can be made of... Figure 3 The cam shown has a gradually changing outer diameter.

[0041] Furthermore, a roller 6 is rotatably mounted on the corrective component 31, and the roller 6 makes rolling contact with the corresponding first cam 421 or second cam 422 to ensure better transmission effect.

[0042] In this utility model, a double-sided alignment mechanism is used such that, driven by the drive member 43, the first cam 421 and the second cam 422 rotate synchronously, pushing the corresponding alignment member 31 to slide relative to the frame 1 after overcoming the elastic force of the elastic member 33. This causes the alignment part 32 to move away from the pad 2, freeing up enough space to place the battery cells on the pad 2. After the battery cells are placed on the pad 2, driven by the drive member 43, the first cam 421 and the second cam 422 rotate synchronously. With the movement of the elastic member 33, the alignment member 31 slides relative to the frame 1, causing the alignment part 32 to move toward the pad 2, thereby aligning the battery cells on the pad 2.

[0043] It should be noted that in the above embodiments, the position of the battery cell is mainly corrected by synchronously pushing the two right-angled sides of the battery cell. In some other embodiments, similar structures can also be used to simultaneously perform multi-sided positioning, such as setting baffles on opposite sides of the two correction components 31, and achieving the centering and positioning of the battery cell by driving the two baffles to move synchronously with the two correction components 31.

[0044] The present invention provides a double-sided alignment mechanism that uses a drive component 43 to drive a cam 42 to rotate, thereby pushing two alignment components 31 to move synchronously toward or away from the pad 2 in two mutually perpendicular directions. This achieves alignment and positioning of the long and wide sides of the battery cell, saving space and reducing manufacturing costs.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
