[0026] As Figs. 1-3As shown, the embodiment provides a battery piece carrier, which comprises a bottom plate 1, a side plate assembly 2, a pressing assembly 3 and a locking assembly 4. The side plate assembly 2 is arranged between the pressing assembly 3 and the bottom plate 1 along a vertical direction and surrounds a receiving cavity B with an open side. The pressing assembly 3 is detachably connected to the side plate assembly 2. The locking assembly 4 has an unlocked state and a locked state. The pressing assembly 3 is locked to the side plate assembly 2 through the locking assembly 4. The locking assembly 4 is provided with a grabbing part for cooperating with a carrying mechanism.

[0027] Before placing the battery pieces, the locking assembly 4 is unlocked, the pressing assembly 3 is detached from the side plate assembly 2, and the battery pieces are placed in the receiving cavity B from top to bottom by manual or automatic equipment such as a robot. After the battery pieces are fully loaded, the pressing assembly 3 is installed on the side plate assembly 2 and locked by the locking assembly 4. The pressing assembly 3 is pressed on the uppermost battery piece, so that all the battery pieces are in a pressed state and loaded in the receiving cavity B, and the edges of the battery pieces are exposed to the open side. The carrying mechanism carries the battery piece carrier into a boat through the grabbing part, and then the boat is sent into a deposition device for atomic layer deposition passivation repair.

[0028] The pressing assembly 3 is locked on the side plate assembly 2 by the locking assembly 4, which ensures that the pressing assembly 3 is stably pressed on the battery pieces, so that all the battery pieces are in a pressed state. On the one hand, it can ensure that all the battery pieces are stably loaded in the receiving cavity B, and on the other hand, it can ensure the passivation process effect. Since the annealing process temperature is high, the battery pieces are easy to break when they are in a pressed state. The detachable connection of the pressing assembly 3 to the side plate assembly 2 can reduce the battery piece breakage rate. The battery pieces are sequentially taken and placed from top to bottom, which is convenient to operate.

[0029] The receiving cavity B can be a cylindrical cavity or a rectangular cavity, etc., which is adaptively set according to the shape of the battery piece. The size of the open side is adaptively set according to the size of the cross-sectional edge of the battery piece. The side plate assembly 2 comprises a first side plate 21 and two second side plates 22 arranged opposite to each other. The first side plate 21 is arranged between the two second side plates 22. The two second side plates 22 are locked by the locking assembly 4 and the pressing assembly 3 respectively. The two ends of the pressing assembly 3 are locked, which improves the locking effect. Exemplarily, the battery piece is a rectangular piece, the receiving cavity B is a rectangular cavity, and the two second side plates 22 are parallel to each other. For the convenience of subsequent description, the two second side plates 22 are arranged apart along the left-right direction, the first side plate 21 is arranged at the rear side, and the open side is located at the front side.

[0030] The locking assembly 4 comprises a fixed block 41 and a locking piece 42 connected to the fixed block 41.

[0032] Further, the grabbing part is formed at one end of the fixed block 41 away from the locking piece 42, and the grabbing part is provided with an arc-shaped surface for cooperation with the carrying mechanism. The grabbing part is formed at one end of the fixed block 41 away from the locking piece 42, so as to facilitate cooperation with the carrying mechanism by avoiding the position of the locking piece 42. Fig. 2 As described above, the grabbing part is provided with an arc-shaped surface for cooperation with the carrying mechanism. In application, the grabbing part can also be provided in a rectangular shape or provided with a slot and other cooperation structures.

[0033] In an embodiment, the fixed block 41 is in sliding connection with the locking piece 42. The locking piece 42 is opened and closed by sliding, which is simple in structure, high in mechanical strength, stable in operation, and can be automatically closed by a mechanical device, so as to facilitate automatic control. The pressing assembly 3 is provided with a clamping groove 311, and the end of the locking piece 42 is provided with a clamping hook 421. The clamping hook 421 is clamped in the clamping groove 311. The clamping hook 421 and the clamping groove 311 cooperate to limit the left-right direction of the pressing assembly 3, prevent the left-right movement of the pressing assembly 3 from affecting the passivation effect, and further improve the locking stability.

[0037] In an embodiment, the second side plate 22 is rotationally connected to the bottom plate 1, and rotating the second side plate 22 can increase the volume of the accommodating cavity B, thereby facilitating the taking out of the battery piece from the accommodating cavity B and reducing the damage caused by the contact between the battery piece and the side plate assembly 2. When the battery piece is taken out, the locking assembly 4 and the pressing assembly 3 are first separated through the locking assembly 4, after the pressing assembly 3 is removed, the second side plate 22 is rotated to expand the gap between the second side plate 22 and the battery piece, thereby facilitating the taking out of the battery piece. In another embodiment, the first side plate 21 can also be rotationally connected to the bottom plate 1, and the taking out of the battery piece is also facilitated.
