Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production and manufacturing, and in particular to a cell loading system and a cell loading box thereof. Background Art

[0002] When loading solar cells, you first need to manually place multiple cells in the loading box one by one, and then move the loading box to the loading table. Then the cells in the loading box are blown apart one by one by a wind knife and are picked up one by one by the suction cup.

[0003] However, to facilitate the placement of battery cells, the size of the loading box is generally larger than the size of the battery cells. Therefore, when the air knife blows, it is easy to blow the battery cells crooked. At this time, when the suction cup picks up the battery cells, the battery cells are likely to rub against the baffle, causing the battery cells to break. Utility Model Content

[0029] See Figure 1 An embodiment of the present application provides a battery cell loading box, which includes a base 100, a plurality of baffles 200, and a plurality of pairs of limiting assemblies 300. The base 100 is provided with a first slide groove 110 extending from the periphery of the base 100 toward the center of the base 100. The plurality of baffles 200 are arranged on the base 100 at intervals, and the plurality of baffles 200 are used to enclose a placement cavity with the base 100, and the placement cavity is used to place battery cells. Each pair of limiting assemblies 300 includes two relatively arranged limiting assemblies 300, and each limiting assembly 300 is respectively slidably arranged with a corresponding first slide groove 110. The two limiting assemblies 300 in the same pair of limiting assemblies 300 are used to limit the battery cells.

[0030] In this embodiment, a plurality of baffles 200 are provided on the base 100. The plurality of baffles 200 are used to enclose a placement cavity with the base 100, and the plurality of battery cells are used to be stacked in sequence and placed in the placement cavity. In order to facilitate the placement of the battery cells, the size of the placement cavity is larger than the size of the battery cells, that is, there is a gap between the battery cells and at least one baffle 200. At the same time, a plurality of pairs of limit assemblies 300 are provided. The limit assemblies 300 are slidably arranged in the first slide groove 110. When the loading box is full of battery cells, the limit assemblies 300 are pushed inward along the periphery of the base 100, so that the two limit assemblies 300 in the same pair of limit assemblies 300 are respectively used to limit the battery cells on both sides of the relative positions of the battery cells, thereby preventing the wind knife from blowing the battery cells crooked, causing the battery cells to be scratched and damaged when the suction cup absorbs the battery cells.

[0031] The base 100 may be a polygonal structure such as a circle, a rectangle, or a triangle, wherein the present application takes the base 100 as a rectangle as an example.

[0032] In some embodiments, the base 100 is a rectangular structure, and the first slide groove 110 is disposed on a diagonal line of the base 100. A limiting groove 311 is defined in the limiting assembly 300, and the limiting groove 311 has a first limiting surface and a second limiting surface, and the first limiting surface is perpendicular to the second limiting surface.

[0033] In this embodiment, the limiting component 300 is slidably arranged in the first slide groove 110, that is, the limiting component 300 can slide along the diagonal of the base 100. When the limiting component 300 slides along the first slide groove 110, the first limiting surface is used to abut against one of the side walls of the battery cell, and the second limiting surface is used to abut against the other limiting surface of the battery cell, thereby quickly achieving the limitation of the battery cell.

[0034] Furthermore, only one pair of limit assemblies 300 is set, and the two limit assemblies 300 in the pair of limit assemblies 300 are respectively set on two opposite diagonals of the base 100. At this time, each limit assembly 300 is used to limit two adjacent side walls of the battery cell. The two diagonally set limit assemblies 300 can achieve the limitation of the four side walls of the battery cell.

[0035] Of course, two pairs of limit assemblies 300 may also be provided, with the limit assemblies 300 being provided on the four corners of the base 100 respectively.

[0036] Alternatively, the limiting components 300 are respectively provided on two opposite side edges of the base 100 or on four side edges of the base 100 .

[0037] In some embodiments, combined Figure 2The limiting assembly 300 includes a limiting column 310, a base 320 and an elastic member 330. The bottom of the limiting column 310 passes through the first slide groove 110 and is connected to the base 320. The elastic member 330 is arranged between the base 100 and the base 320.

[0038] In this embodiment, the elastic member 330 is disposed between the base 100 and the bottom bracket 320. The elastic force of the elastic member 330 is used to secure the limiting post 310 while facilitating the movement of the limiting post 310. When the air knife is blowing and causes the battery cell to collide with the limiting post 310, the limiting post 310 is secured by the elastic member 330, which provides a cushioning effect for the limiting post 310, preventing the battery cell from being broken.

[0039] In some embodiments, a blocking piece 400 is provided at one end of the baffle 200 away from the base 100 , and the blocking piece 400 extends along the length direction of the base 100 .

[0040] In this embodiment, the base 100 is a rectangular structure with four sets of baffles 200 disposed thereon. The four sets of baffles 200 correspond to the four sides of the base 100, and each set of baffles 200 includes two baffles 200. The ends of the baffles 400 are connected to the two baffles 200 in the same set. The baffles 400 further limit the position of the battery cells, preventing them from tilting during the air knife blowing process.

[0041] In other embodiments, a baffle 200 may be provided in the middle of each side of the rectangular base 100 , and the baffle 400 may be vertically provided on the baffle 200 and form a T-shaped structure with the baffle 200 .

[0042] In some embodiments, the baffle 200 includes a column section 210 and a gradient section 220. The column section 210 is set on the base 100, and the gradient section 220 is located at the end of the column section 210 away from the base 100. The thickness of the gradient section 220 gradually decreases from the end close to the base 100 to the end away from the base 100. The inner walls of the column section 210 and the gradient section 220 are flush and both are perpendicular to the base 100.

[0043] In some embodiments, when loading cells, multiple cells need to be manually placed in the loading box one by one. When the cells approach the box, they are prone to collision with the outer wall of the box. In this embodiment, the thickness of the column section 210 remains unchanged, and the maximum thickness of the gradient section 220 is the same as the thickness of the column section 210. The column section 210 is used to support the gradient section 220. From bottom to top, the gradient section 220 gradually approaches the center of the base 100, thereby effectively preventing the cells from colliding with the outer wall of the baffle 200 during the placement process.

[0044] In other embodiments, the thickness of the column section 210 gradually decreases from the end close to the base 100 to the end away from the base 100, and the maximum thickness of the gradient section 220 is the same as the minimum thickness of the column section 210. For example, the baffle 200 has a triangular structure, with the bottom of the baffle 200 being the column section 210 and the upper portion of the baffle 200 being the gradient section 220.

[0045] Furthermore, the outer wall of the gradient section 220 is an arc-shaped surface 221 .

[0046] In this embodiment, the outer wall of the baffle 200 away from the placement cavity is a curved surface 221, which is used to reduce the sharp corners on the outer wall of the baffle 200. When the battery cell collides with the outer wall of the baffle 200, the curved surface 221 can effectively reduce damage to the battery cell.

[0047] In some embodiments, the outer wall of the limiting component 300 away from the placement cavity is an arc-shaped structure.

[0048] In this embodiment, the limiting post 310 is a cylindrical structure. A limiting groove 311 is defined near the center of the base 100 to limit the position of the battery cell. The cylindrical structure of the limiting post 310 effectively reduces damage to the battery cell when it collides with the outer wall of the baffle 200.

[0049] In some embodiments, a buffer layer and a rubber pad layer are provided on the inner wall of the baffle 200 , and the rubber pad layer is located on a side of the buffer layer away from the inner wall of the baffle 200 .

[0050] In this embodiment, the buffer layer can be foam with a thickness of 1 mm. The foam has a vibration-damping effect. The rubber pad layer is a wear-resistant tape. The wear-resistant tape is wrapped around the outside of the buffer layer to prevent the baffle 200 located in the buffer layer from being exposed and the baffle 200 from rubbing against the battery cell and damaging the battery cell.

[0051] In some embodiments, a second sliding groove 120 extending from the periphery of the base 100 toward the center of the base 100 is defined on the base 100 , and the baffle 200 is slidably connected to the second sliding groove 120 .

[0052] The baffle 200 is slidably connected to the second chute 120, allowing the size of the placement slot to be adjusted according to the size of the battery cell. Handles 140 are provided on opposite sides of the base 100. The handles 140 ensure stability when handling the material box, ensuring safety during the transportation of the battery cells.

[0053] Specifically, the handle 140 is disposed between two baffles 200 in the same baffle group.

[0054] An embodiment of the present application also provides a battery cell loading system, which includes a lifting mechanism 500, a wind knife mechanism 600 and a battery cell loading box. A through hole is opened in the middle of the base 100, and the lifting mechanism 500 can pass through the through hole to lift the battery cells in the placement cavity. The wind knife mechanism 600 is arranged on the upper part of the baffle 200 to blow air to the battery cells located on the upper part of the placement cavity.

[0055] In this embodiment, the air knife mechanism 600 is located above the baffle 200. When the loading box is placed on the loading platform, the air knife blows air to separate the battery cells in the upper portion of the placement chamber one by one, and the suction cups located above the box grab the battery cells one by one. At the same time, the lifting mechanism 500 extends through the through hole into the placement chamber and continuously lifts the battery cells in the placement chamber until all the battery cells are sucked away by the suction cups.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
