Description

Technical Field

[0001] This application relates to the field of solar cell string production technology, specifically to a cell stacking platform and stacking mechanism. Background Technology

[0002] The production process of the battery string is as follows: multiple battery cells are laid out, and a welding ribbon group is laid on each battery cell, with the front half of the welding ribbon group laid on the upper surface of the battery cell and the rear half of the welding ribbon group extending out of the battery cell. Then, multiple battery cells and multiple welding ribbon groups are moved so that the rear half of the welding ribbon group corresponding to the previous battery cell overlaps the lower surface of the next battery cell. Finally, welding is performed to form a battery string.

[0003] In existing technology, solar cells are laid on stacking tables, with each stacking table supporting one solar cell. Then, solder ribbons are laid on the solar cells. By adjusting the distance between adjacent stacking tables, the latter half of the solder ribbon group corresponding to the previous solar cell overlaps the lower surface of the next solar cell. However, when laying solar cells on the stacking tables, it is difficult to place them in the target position, affecting the quality of the manufactured battery strings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application proposes a cell stacking stage and stacking mechanism that can adjust the position of the cells.

[0005] On one hand, this application provides a solar cell stacking stage, which includes: a base, a support, a tray, a lifting seat, and a driving component. The support and the driving component are disposed on the base. The driving component and the lifting seat are driven together and drive the lifting seat to move up and down. Multiple trays are provided and spaced apart. The rear half of the tray is fixed on the support. The front half of the tray is forked and has two guide grooves spaced apart. The lifting seat includes multiple support rods that correspond one-to-one with the trays. The top of the support rod is forked. The middle part of the tray is located in the fork at the top of the support rod. At least two trays have grooves in their middle parts. The bottom of the groove has a through hole. The support rod corresponding to the tray with the groove has a pin. The pin passes through the through hole. A lever is provided in the groove. One end of the lever is rotatably connected to the side wall of the groove, and the other end of the lever covers the through hole.

[0006] Furthermore, the groove is formed in the middle of the two trays located at both ends.

[0007] Furthermore, one end of the lever is provided with two spaced-apart bearings, which are rotatably connected to the side wall of the groove via a pin. A torsion spring is sleeved on the pin and located between the two bearings. One end of the torsion spring abuts against the support plate, and the other end of the torsion spring abuts against the lever.

[0008] Furthermore, a groove is provided on the side wall of the lever opposite to the through hole.

[0009] Furthermore, the support base is provided with magnets, which are located on both sides of the plurality of trays.

[0010] Furthermore, the driving component includes two cylinders disposed at both ends of the lifting seat, the driving ends of the two cylinders are integrally disposed, and the driving ends of the cylinders are connected to the lifting seat.

[0011] Furthermore, the support base is also provided with a limiting block, which is located above the drive end.

[0012] Furthermore, the support base is provided with multiple through slots, which are located between two adjacent trays.

[0013] On the other hand, this application provides a stacking mechanism, which includes a plurality of battery cell stacking platforms arranged linearly. The bases of two adjacent battery cell stacking platforms can move closer to or further away from each other. Among two adjacent battery cell stacking platforms, the rear half of the tray of one battery cell stacking platform can extend into the fork of the front half of the tray of the other battery cell stacking platform.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0015] The solar cell is placed on the rear half of the tray. The drive unit moves the lifting seat upward, which in turn moves the support rod and the ejector pin upward. After the support rod moves upward, its top can serve as a support point for bending the welding strip. The rear half of the welding strip is located on the solar cell, while the front half is bent into the guide groove. After the ejector pin moves upward, it lifts the lever, causing the lever to rotate and push the solar cell on the tray, moving the solar cell to the target position. Attached Figure Description

In the description of this utility model, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] like Figures 1-6 As shown, this utility model provides a battery cell stacking stage, including: a base 10, a support 20, a tray 30, a lifting seat 40, and a driving component 50. The support 20 and the driving component 50 are disposed on the base 10. The driving component 50 is motive-connected to the lifting seat 40 and drives the lifting seat 40 to move up and down. Multiple trays 30 are provided and spaced apart. The rear half of the tray 30 is fixed to the support 20, and the front half of the tray 30 is forked and has two spaced guide grooves 31. The lifting seat 40 includes multiple... Support rods 41 are provided one-to-one with the support plates 30. The top of the support rods 41 is forked, and the middle of the support plate 30 is located in the fork at the top of the support rod 41. At least two support plates 30 have grooves 32 in their middle, and the bottom of the grooves 32 has through holes. The support rods 41 corresponding to the support plates 30 with grooves 32 are provided with pins 43, which pass through the through holes. A lever 60 is provided in the groove 32. One end of the lever 60 is rotatably connected to the side wall of the groove 32, and the other end of the lever 60 covers the through hole. The lifting seat 40 also includes a base plate 42. Multiple support rods 41 are vertically and spacedly fixed on the base plate 42, and the base plate 42 is connected to the driving end of the driving component 50.

[0025] exist Figure 1 and Figure 2 In the middle position, the lifting seat 40 is in the low position, and the lever 60 is not lifted by the ejector pin; at this time, the lever 60 is horizontal. Figure 3 and Figure 4 In the process, the lifting seat 40 is in a high position, and the lever 60 is lifted by the ejector pin, at which point the lever 60 is upright. During use, the battery cell is placed on the rear half of the tray 30, with the lifting seat 40 in a low position. Then, the drive unit 50 drives the lifting seat 40 upwards, causing the ejector pin 43 to move upwards and lift the lever 60. The lever 60 rotates and contacts the edge of the battery cell, pushing the battery cell to the target position. Lever 60s are installed in the grooves 32 of at least two trays 30, allowing for alignment of the battery cell from at least two points. After alignment, a welding strip is laid on the battery cell, with half of the welding strip on the battery cell and the front half above the guide groove 31. The top of the support rod serves as a support point for bending the welding strip, bending the front half of the welding strip into the guide groove 31.

[0026] It should be noted that the spacing between any two adjacent guide slots 31 is the same as the spacing between two adjacent main grid lines on the battery string.

[0027] In an optional embodiment of this utility model, a groove 32 is provided in the middle of the two support plates 30 located at both ends, and a lever 60 is provided in each groove 32. The pin 43 is provided on the two support rods 41 located at both ends. The lever 60 contacts the points at both ends of the battery cell, resulting in a good alignment effect.

[0028] In an optional embodiment of this utility model, one end of the lever 60 is provided with two spaced-apart bearings 61. The two bearings 61 are rotatably connected to the side wall of the groove 32 via a pin 62. A torsion spring 63 is sleeved on the pin 62, located between the two bearings 61. One end of the torsion spring 63 abuts against the support plate 30, and the other end of the torsion spring 63 abuts against the lever 60. When the driving member 50 drives the lifting seat 40 to descend, the torsion spring 63 can return the lever 60 to a horizontal state.

[0029] In an optional embodiment of this utility model, a sliding groove is provided on the side wall of the lever 60 opposite to the through hole. When the ejector pin 43 pushes up the lever 60, the top of the ejector pin 43 moves along the sliding groove, which plays a guiding role and prevents the lever 60 from axially shaking during rotation.

[0030] In an optional embodiment of this utility model, a magnet 21 is provided on the support base 20, and the magnet 21 is located on both sides of the plurality of trays 30. After the welding strip is bent, a press is placed on the battery cell to fix the battery cell and the welding strip. At this time, the two ends of the press are attracted by the magnet, which can increase the downward pressure and keep the press stable.

[0031] In an optional embodiment of this utility model, the driving component 50 includes two cylinders 51 disposed at both ends of the lifting seat 40. The driving ends of the two cylinders 51 are integrally disposed and connected to the lifting seat 40, which can simplify the structure of the battery cell stacking table.

[0032] In an optional embodiment of the present invention, a limiting block 22 is further provided on the support base 20. The limiting block 22 is located above the drive end and is used to limit the drive stroke of the cylinder 51.

[0033] In one optional embodiment of this utility model, the support base 20 is provided with a plurality of through slots, which are located between two adjacent pallets 30. The transport fork can extend into the through slot to transport the battery cells and welding strips laid together.

[0034] This utility model also provides a stacking mechanism for laying battery strings, which includes multiple battery stacking platforms arranged linearly. The bases 10 of two adjacent battery stacking platforms can move closer or further apart from each other. The rear half of the tray 30 of one battery stacking platform can extend into the fork of the front half of the tray 30 of the other battery stacking platform.

[0035] In use, firstly, multiple cell stacking platforms are spaced far apart. Then, cells are laid on the rear half of the tray 30 and aligned. Next, welding ribbons are laid on the cells and the front half of the welding ribbons is bent into the guide groove 31. Then, multiple cell stacking platforms are brought closer together, so that the rear half of the tray 30 of one of the adjacent cell stacking platforms extends into the fork of the front half of the tray 30 of the other cell stacking platform. At this time, the welding ribbons bent into the guide groove 31 are located below the adjacent cells, completing the laying of the cell string.

[0036] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application are still within the scope of this application.
