Description

[Technical Field]

[0001] This utility model belongs to the field of battery cell manufacturing technology, and in particular relates to a BC battery cell cassette that effectively prevents microcracks. [Background Technology]

[0002] During the manufacturing process of solar cells, a battery storage box is needed to store stacked solar cells. Existing technology, patent CN220691983U, discloses a battery storage box. Although it achieves flexible size adjustment, the battery storage box uses baffles around its perimeter to directly contact the solar cells and limit their movement. During the process of placing and removing solar cells, the solar cells are prone to hard collisions with the baffles, resulting in microcracks. Furthermore, the inner side of the baffle is a vertical surface, and during the vertical movement of the solar cells, neither the solar cells nor the storage box can shake or shift, otherwise they are prone to collision.

[0003] Therefore, it is necessary to provide a new BC cell cassette that effectively prevents microcracks to solve the above-mentioned technical problems. [Utility Model Content]

[0004] The main purpose of this invention is to provide a BC cell cassette that effectively prevents microcracks. It uses flexible side baffles to limit the cell's perimeter, avoiding hard impacts that could cause microcracks and improving cell safety.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a BC battery cell cassette that effectively prevents microcracks, comprising a supporting base plate and at least one hopper disposed on the supporting base plate; the hopper comprises several baffles, each baffle comprising a supporting upright plate and a flexible side baffle strip disposed on the inner side of the supporting upright plate, wherein there is a gap between the flexible side baffle strip and the inner surface of the supporting upright plate.

[0006] Furthermore, the flexible side baffles form the inner wall of the enclosure of the hopper.

[0007] Furthermore, the hopper is provided in two or more parts.

[0008] Furthermore, a movable support plate is provided at the bottom of the hopper, and a hollowed-out slot is provided on the support plate corresponding to the position of the hopper.

[0009] Furthermore, the position of the enclosure panel can be adjusted and mounted on the supporting base plate.

[0010] Furthermore, the circumference of the hopper gradually decreases from top to bottom.

[0011] Furthermore, on the side surface of the support plate facing the hopper, a first protrusion is provided near the top and a second protrusion is provided near the bottom. One side of the flexible side baffle abuts against the first and second protrusions, thereby creating the gap between the flexible side baffle and the support plate.

[0012] Furthermore, the protrusion dimension of the second protrusion is larger than that of the second protrusion.

[0013] Furthermore, the support plate is provided with a head locking block that presses down on both ends of the flexible side guard strip.

[0014] Furthermore, on the outer surface of the supporting plate, a third protrusion is provided near the top and bottom positions. The two ends of the flexible side guard band wrap around the third protrusion and are then locked and fixed by the band head locking block.

[0015] Furthermore, two adjacent hoppers share a common support plate on their adjacent sides, and the support plate has a first protrusion and a second protrusion on opposite sides; the flexible side baffles are wrapped around one side surface of the support plate to the other side surface, and the two ends of the baffles are locked and fixed at the bottom of opposite sides of the support plate by baffle locking blocks; the top of the support plate is provided with a groove, and the flexible side baffles wrapped around the top of the support plate are locked and fixed in the groove by the baffle locking blocks.

[0016] Compared with existing technologies, the beneficial effects of this utility model's BC cell hopper for effectively preventing microcracks are as follows: Flexible side baffles are provided on the enclosure plate constituting the hopper, with a deformation gap between the flexible side baffles and the enclosure plate. Utilizing the flexible side baffles as the inner wall of the hopper avoids hard contact with the periphery of the cells. Even if the cells collide with the inner wall of the enclosure, the flexible deformation of the side baffles can effectively release the impact force, greatly reducing the risk of microcracks and improving the safety of the cells. The enclosure plate is flexibly adjustable and can be used to store cells of various specifications. Protrusions are provided on the top and bottom of one side of the enclosure plate, with one side of the flexible side baffles abutting against the two protrusions, forming a deformation gap with the enclosure plate. Furthermore, by designing the bottom protrusion to be larger, the flexible side baffles are tilted after abutting against the protrusions, thus forming a hopper that is wider at the top and narrower at the bottom, further reducing the risk of microcracks in the cells.

Detailed Implementation Methods

[0026] Example 1:

[0027] Please refer to Figures 1-4 This embodiment is a BC cell cassette 100 that effectively prevents microcracks, which includes a support base plate 1 and at least one hopper 2 disposed on the support base plate 1.

[0028] In this embodiment, two hoppers 2 are provided, each holding two stacks of battery halves. In other embodiments, more than two hoppers 2 may be provided.

[0029] The silo 2 is surrounded by several baffles 23. The bottom of the silo 2 is provided with several raised blocks 21 and movable support plates 22 placed on the raised blocks 21.

[0030] The support base plate 1 is provided with several strip-shaped mounting slots 11. The position of the baffle plate 23 is adjustable and installed on the support base plate 1, and its position can be adjusted along the strip-shaped mounting slots 11. The position of the baffle plate 23 is flexibly adjustable to accommodate battery cells of various sizes.

[0031] Positioning grooves 12 are provided on the left and right sides of the support base plate 1 so that the external positioning mechanism can position the entire material box.

[0032] A perforated slot 13 is provided on the support base plate 1 at the position corresponding to the hopper 2, so that the lifting mechanism can pass through the perforated slot 13 and extend into the hopper 2 to lift the movable support plate 22 upward.

[0033] To prevent cracks caused by hard collisions between the battery cells and the surface of the baffle 23, this embodiment features an optimized structural design for the baffle 23. Specifically, the baffle 23 includes a supporting upright plate 231 and flexible side baffles 232 arranged inside the supporting upright plate 231. A gap 233 exists between the flexible side baffles 232 and the inner surface of the supporting upright plate 231, allowing the battery cells in the hopper 2 to be confined to their peripheral contours solely by the flexible side baffles 232. This effectively avoids hard contact with the edges of the battery cells and reduces the risk of microcracks.

[0034] The flexible side baffles 232 are set vertically, and all the flexible side baffles 232 in the same hopper 2 surround to form the hopper 2. The circumference of the hopper 2 gradually decreases from top to bottom. On the one hand, this improves the neatness of the battery cells stored in the hopper. On the other hand, if the battery cells stacked in the hopper 2 are not neat enough, when the movable support plate 22 is lifted upward, the battery cells that exceed the standard position area are prone to collide with the inner wall of the hopper 2. By designing the hopper 2 with a structure that is wider at the top and narrower at the bottom, the circumference of the upper part of the hopper 2 can be increased while ensuring that the position of the battery cells stored inside meets the requirements, thus reducing the probability of the battery cells colliding with the inner wall of the hopper 2. In addition, if the battery cells are stacked upward, there is more room for vibration error when the equipment shakes, further reducing the probability of collision.

[0035] To achieve a top-wide, bottom-narrow design for the hopper 2, a first protrusion 2311 is provided near the top of the supporting plate 231 facing the hopper 2, and a second protrusion 2312 is provided near the bottom. The protrusion size of the second protrusion 2312 is larger than that of the first protrusion 2312. One side of the flexible side baffle 232 abuts against the first protrusion 2311 and the second protrusion 2312, creating a gap 233 between the flexible side baffle 232 and the supporting plate 231. The gap 233 provides flexible deformation space for the flexible side baffle 232. When the edge of the battery cell collides with the flexible side baffle 232, the collision force can be released by the flexible deformation of the flexible side baffle 232, preventing the battery cell from cracking and also correcting the battery cell to the set position area. Compared to the first protrusion 2311, by designing the second protrusion 2312 to be more prominent, the flexible side baffle 232 can be tilted after it abuts against the support plate 231, thereby achieving the structure of the hopper 2 being wider at the top and narrower at the bottom.

[0036] The flexible side guard strip 232 may wear down after prolonged use, so it needs to be replaced regularly. To improve the ease of replacement, this embodiment includes a head locking block 234 on the support plate 231 to press the two ends of the flexible side guard strip 232. To reduce the probability of the two ends of the flexible side guard strip 232 being loosened, a third protrusion 2313 is provided on the outer surface of the support plate 231 near the top and bottom. The two ends of the flexible side guard strip 232 wrap around the third protrusion 2313 and are then locked and fixed to the support plate 231 by the head locking block 234. Through the structural design of the third protrusion 2313, the head of the flexible side guard strip 232 forms a bent structure, which is less likely to be loosened by pulling compared to a linear structure.

[0037] Please refer to Figure 5 In another embodiment, two adjacent hoppers 2 share a single support plate 231 on their adjacent sides. The opposite sides of the support plate 231 face the hopper 2, and a first protrusion 2311 and a second protrusion 2312 are provided on the opposite side surfaces of the support plate 231. The installation structure of the flexible side baffle 232 on the support plate 231 is as follows: the flexible side baffle 232 wraps around one side of the support plate 231 to the other side surface, and the two ends of the baffle are respectively locked and fixed to the bottom of the opposite sides of the support plate 231 by baffle locking blocks 234; a groove 2314 is provided on the top of the support plate 231, and the flexible side baffle 232 wrapped around the top of the support plate 231 is locked and fixed in the groove 2314 by the baffle locking blocks 234.

[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
