[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a Figures 1-4 square battery cell shelling diversion component and shelling device as shown.

[0027] Among them, a square battery cell shelling diversion component includes: a diversion plate 11; the diversion plate 11 has a square structure, and two groups of first diversion blocks 12 are symmetrically arranged on the upper and lower sides of one side wall of the diversion plate 11, and two groups of second diversion blocks 16 are symmetrically arranged on the left and right sides of one side wall of the diversion plate 11; the two groups of first diversion blocks 12 are driven by two groups of first cylinders 14, and the two groups of second diversion blocks 16 are driven by two groups of second cylinders 18;

[0028] On one side of the inner walls of the first flow guide block 12 and the second flow guide block 16, multiple groups of flow guide bands 20 are evenly distributed. The flow guide bands 20 are integrally formed of rubber material and are arranged in a triangular shape. The flow guide bands 20 are located inside the circular opening formed by the first flow guide block 12 and the second flow guide block 16, closer to the battery case inlet side, and the flow guide bands 20 are inclined towards the battery case inlet side.

[0029] During actual use, before the square battery cell enters the case, it needs to pass through the flow guide assembly first. Before the battery cell enters the case, the first cylinder 14 and the second cylinder 18 are in their original states. At this time, the first flow guide block 12 is attached to the first baffle 13, and the second flow guide block 16 is attached to the second baffle 17;

[0030] When the battery cell is pushed into the inlet of the flow guide plate 11, the first cylinder 14 and the second cylinder 18 work, respectively pushing the first flow guide block 12 and the second flow guide block 16 to combine. The rectangular gap for the battery cell to pass through is formed between the combined first flow guide block 12 and the second flow guide block 16. Since the inner walls of the first flow guide block 12 and the second flow guide block 16 are both provided with flow guide bands 20, under the action of the flow guide bands 20, the mylar film coated on the battery cell can fit onto the battery cell before entering the case, thereby avoiding the problem of the battery cell rubbing against the case opening when the mylar film coated on the battery cell is not completely coated, and further avoiding the problem of the case squeezing the battery cell. The battery cell enters the case more smoothly and conveniently, enabling the battery cell case loading device to operate normally and avoiding problems such as equipment impact and downtime;

[0031] When the battery cell is completely in the case, the first cylinder 14 and the second cylinder 18 drive the first flow guide block 12 and the second flow guide block 16 to reset until the next battery cell enters the case for operation.

[0032] Furthermore, please refer to Figure 2 :

[0033] At the upper and lower ends of one side wall of the flow guide plate 11, first baffles 13 are symmetrically arranged. Two groups of first cylinders 14 are respectively installed outside the two groups of first baffles 13. The piston rod ends of the first cylinders 14 penetrate through the first baffles 13 and are fixedly connected to the side walls of the first flow guide blocks 12. The two groups of first cylinders 14 are arranged synchronously. On the outer walls of the two groups of first flow guide blocks 12, two groups of first guide rods 15 are symmetrically arranged. The first guide rods 15 are slidably inserted into the first baffles 13, and limit blocks for limiting the stroke of the first cylinders 14 are provided at the ends of the first guide rods 15.

[0034] On the upper and lower ends of one side wall of the deflector 11, second baffles 17 are symmetrically arranged. Two groups of second cylinders 18 are respectively installed on the outer sides of the two groups of second baffles 17. The end of the piston rod of the second cylinder 18 penetrates through the second baffle 17 and is fixedly connected to the side wall of the second deflector block 16. The two groups of second cylinders 18 are arranged synchronously. On the outer walls of the two groups of second deflector blocks 16, two groups of second guide rods 19 are symmetrically arranged. The second guide rods 19 are slidably inserted into the second baffles 17, and limit blocks for limiting the stroke of the second cylinders 18 are arranged at the ends of the second guide rods 19.

[0035] Two groups of first deflector blocks 12 are driven by two groups of synchronously arranged first cylinders 14, and two groups of second deflector blocks 16 are driven by two groups of synchronously arranged second cylinders 18. A first guide rod 15 with a limit block is arranged on the first deflector block 12, and a second guide rod 19 with a limit block is arranged on the second deflector block 16. The designs of the first guide rod 15 and the second guide rod 19 can play a good guiding role during the combination process of the first deflector block 12 and the second deflector block 16, avoiding deviation during the combination process of the first deflector block 12 and the second deflector block 16.

[0036] Limit blocks are arranged on both the first guide rod 15 and the second guide rod 19, which can respectively limit the strokes of the first cylinder 14 and the second cylinder 18. When the limit block on the first guide rod 15 fits against the first baffle 13, the first deflector block 12 just reaches the designated position. When the limit block on the second guide rod 19 fits against the second baffle 17, the second deflector block 16 just reaches the designated position, improving the accuracy when the first deflector block 12 and the second deflector block 16 are combined.

[0040] In actual use, the diversion assembly is installed between the first base 1 and the second base 2. The battery cell is pushed through the pushing mechanism on the first base 1. The sliders 5 on the two groups of electric guide rails 4 drive the push plate 6 to push the battery cell towards the inlet of the diversion plate 11;

[0041] The battery cell housing is placed on the second base 2 and positioned by the positioning plate 9. The battery cell passes through the diversion assembly, and after the externally wrapped mylar film is adhered, it enters the housing. When the battery cell is completely inside the housing, the third cylinder 8 drives the positioning plate 9 to rise, and the battery cell with the housing is then conveyed to the next process through the conveying rollers 3.

[0042] The structure of this device is simple. Through cooperation with the diversion assembly, it can quickly perform the operation of inserting the square battery cell into the housing, and it is not easy to have accidents of squeezing the battery cell, improving the efficiency of battery processing.

[0043] In addition, please refer to Figure 4 :
