Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, specifically to a photovoltaic cell string carrier. Background Technology

[0002] Solar energy, as a new type of energy source, is increasingly being widely used due to its green and renewable characteristics. Since the beginning of the 21st century, solar power generation technology has developed rapidly, and the photovoltaic industry has become one of the world's fastest-growing high-tech industries.

[0003] Stringing is an important step in the manufacturing process of photovoltaic modules. After the photovoltaic modules are stringed together by the welding machine, they will undergo EL testing. Modules with defects such as poor solder joints, broken grids, and microcracks will be automatically rejected and placed into the carrier tray.

[0004] The quality of the carrier tray directly affects the success rate of battery string repairs. In daily use, carrier trays are often placed upright to reduce floor space. Currently, when carrier trays are placed upright, the ends of the trays are prone to contact with the ground and deform. When placing the battery strings into the carrier tray, the battery strings are likely to touch the deformed areas of the carrier tray, which can lead to microcracks, fragments, etc. in the battery strings. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic cell string carrier to solve the problem that the end of the carrier is prone to deformation in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a photovoltaic cell string carrier, including a bottom wall and two side walls disposed on opposite sides of the bottom wall, the bottom wall and the two side walls forming a receiving part extending along a first direction, the end of the side wall having an inclined surface, and the two sides of the two ends of the bottom wall respectively being provided with an extension portion extending outward from the edge of the bottom wall, and the extension portion being provided with an anti-slip sleeve.

[0007] In some embodiments, the inclined surface gradually slopes from the top of the sidewall toward the bottom wall in a direction toward the edge of the bottom wall.

[0008] In some embodiments, in the first direction, the anti-slip sleeve extends beyond the end edge of the bottom wall, and when the empty tray is placed upright, the anti-slip sleeve can contact the ground to prevent the tray from slipping.

[0009] In some embodiments, the edge of the extension is flush with the end edge of the bottom wall.

[0010] In some embodiments, the distance L2 from the end of the sidewall to the end edge of the bottom wall is 8-15 mm, and the end of the sidewall and the end edge of the bottom wall are kept at an appropriate distance, which further reduces the risk of sidewall end deformation.

[0011] In some embodiments, the inclined surface has an inclination angle R of 15-45° relative to the bottom wall, and the side wall has a height H of 10-20 mm relative to the upper surface of the bottom wall. The inclined surface has a suitable inclination angle and height, which helps to reduce the deformation at the end of the side wall.

[0012] In some embodiments, in the second direction, the anti-slip sleeve does not extend beyond the inner surface of the sidewall on the corresponding side, and the second direction is perpendicular to the first direction. In the second direction, the anti-slip sleeve does not extend beyond the inner surface of the sidewall on the corresponding side, so that the anti-slip sleeve does not affect the sliding of the battery string from the end of the carrier.

[0013] In some embodiments, in the second direction, the distance L2 from the anti-slip sleeve to the inner surface of the sidewall on the corresponding side is 1.5-5 mm.

[0014] In some embodiments, the anti-slip sleeve is a rubber sleeve.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] This invention features an inclined surface on the side wall end of the carrier tray. When the carrier tray is placed upright, the side wall of the carrier tray does not contact the ground, reducing the risk of deformation at the side wall end. This reduces the probability of microcracks or fragments in the battery string due to deformation at the end of the carrier tray, thereby improving the yield rate of the battery cells. At the same time, the carrier tray has extensions on both sides of the bottom wall end, and anti-slip sleeves are wrapped on the extensions. The anti-slip sleeves have a cushioning and anti-slip function, which can prevent the carrier tray from slipping and make the carrier tray place stably on the ground. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1 to 4 This utility model provides a photovoltaic cell string carrier, including a bottom wall 11 and two side walls 12 disposed on opposite sides of the bottom wall 11. The bottom wall 11 and the two side walls 12 form a storage part 10 extending along a first direction D1. The ends of the side walls 12 have inclined surfaces 120. The two sides of the two ends of the bottom wall 11 are respectively provided with extension parts 13 extending outward from the edge of the bottom wall 11. Anti-slip sleeves 2 are provided on the extension parts 2.

[0030] The battery strings are placed in the storage section 10 of the carrier tray. The side wall 12 has a limiting effect on the opposite edges of the battery strings. Therefore, when the side wall 12 deforms, it will squeeze the battery strings, causing microcracks or even breakage. However, the carrier tray of this invention has an inclined surface 120 at the end of the side wall 12. When the carrier tray is placed upright on the ground, the side wall 12 does not contact the ground because of the inclined surface 120. Therefore, the side wall 12 will not deform. This allows the side wall 12 to limit the opposite edges of the battery strings without squeezing them due to deformation. This reduces the probability of microcracks and fragmentation of the battery strings caused by carrier tray deformation, and improves the yield of battery cells.

[0031] Meanwhile, the tray has extensions 13 on both sides of the bottom wall 11. Anti-slip sleeves 2 are wrapped around the extensions 13. When the empty tray is placed upright, the anti-slip sleeves 2 can contact the ground. The anti-slip sleeves 2 have the functions of buffering and anti-slip to prevent the tray from slipping and to make the tray stable on the ground.

[0032] In some embodiments, the inclined surface 120 gradually slopes from the top of the side wall 12 toward the bottom wall 11 in the direction toward the edge of the bottom wall 11. When the empty tray is placed upright, the side wall 12 of the tray is not in contact with the ground, so that the side wall will not deform due to contact with the ground.

[0033] In some embodiments, the distance L between the end of the sidewall 12 and the end edge of the bottom wall 11 is 8-15 mm, and the end of the sidewall 12 and the end edge of the bottom wall 11 are kept at an appropriate distance, which further reduces the risk of deformation of the end of the sidewall 12.

[0034] In some embodiments, the inclined angle R of the inclined surface 120 relative to the bottom wall 11 is 15-45°, and the height H of the side wall 12 relative to the upper surface of the bottom wall 11 is 10-20mm. The inclined surface 120 has a suitable inclined angle and height, which helps to reduce the deformation at the end of the side wall 12.

[0035] In some embodiments, in the first direction D1, the anti-slip sleeve 2 extends beyond the end edge of the bottom wall 11. When the empty tray is placed upright, the anti-slip sleeve 2 can make contact with the ground first, thereby providing cushioning and anti-slip effects.

[0036] In some embodiments, the edge of the extension 13 is flush with the end edge of the bottom wall 11.

[0037] In some embodiments, in the second direction D2, the anti-slip sleeve 2 does not extend beyond the inner surface of the corresponding sidewall 12, and the second direction D2 is perpendicular to the first direction D1. In the second direction D2, the anti-slip sleeve 2 does not extend beyond the inner surface of the corresponding sidewall 12, so that the anti-slip sleeve 2 does not affect the sliding of the battery string from the end of the carrier tray.

[0038] In some embodiments, in the second direction D2, the distance L2 from the anti-slip sleeve 2 to the inner surface of the corresponding side wall 12 is 1.5-5mm.

[0039] In some implementations, the anti-slip sleeve 2 is a rubber sleeve.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
