The limiting member 13 can be a limiting rod, a limiting plate, a limiting block or other structures, and its function is to use the limiting member 13 to fix the long side of a single battery so that each battery does not move in the second direction b during separation and pressing. Preferably, the second direction b is the front and back direction; the positioning component 2 can move the separation component 3 to the position of the defective battery, wherein the first mounting plate 21 is installed in a bent shape on the fourth plate 42 of the pressing assembly 4 and extends upward, and the moving module 22 is preferably a lead screw structure with a simple structure and easy installation. 23 can move up and down on the lead screw structure, thereby changing the position of the separation component 3 in the first direction a, so as to adapt to the position of the bad batteries in different bad battery stacks; the separation component 3 can move all the batteries above the bad battery upward, so as to expose the bad battery so as to remove the bad battery, wherein the first telescopic module 31 can change the opening size of the first clamp 32, so as to adapt to batteries of different sizes, the first clamp 32 can clamp the battery above the bad battery, and move upward, so as to separate the bad battery from the battery above it, so as to facilitate the removal of the bad battery; finally, the battery stack with the bad battery removed is re-pressed by the pressing component 4, and at least one of the third plate 41 and the fourth plate 42 can move along the support 43, so as to realize the pressing and loosening of the battery stack.

[0034] Specifically, Figure 1-3 and Figure 6 As shown, the first plate 11 and the pressing plate 15 can slide along the first direction a on the stopper 13, the third plate 41 can slide along the first direction a on the support member 43, the second plate 12 and the support plate 16 are fixedly mounted on the stopper 13, and the fourth plate 42 is fixedly mounted on the support member 43.

[0040] In some embodiments of the present application, Figure 5As shown, the separation assembly 3 is further provided with a stabilizing portion 33, the stabilizing portion 33 is mounted on the second mounting plate 23 and slidably connected to the support member 43, and the first telescopic module 31 is mounted on the stabilizing portion 33. The stabilizing portion 33 is provided between the second mounting plate 23 and the first telescopic module 31, and can play a role in connecting the two, and by means of a slidable connection with the support member 43, the separation assembly 3 can stably move with the movement of the second mounting plate 23, thereby improving the reliability of the overall structure.

[0041] In some embodiments of the present application, Figure 5 As shown, the separation assembly 3 is further provided with a second telescopic module 34 and a second clamping jaw 35 installed on the second telescopic module 34, the first clamping jaw 32 and the second clamping jaw 35 are spaced apart along the first direction a, the second telescopic module 34 is installed on the second mounting plate 23, and the first telescopic module 31 can move relative to the second telescopic module 34 along the first direction a. The second telescopic module 34 can control the opening and tightening of the second clamping jaw 35. When the separation assembly 3 is working, the second clamping jaw 35 is first used to clamp the lower battery of the defective battery to prevent the battery near the lower side of the defective battery from moving upward due to adhesion between the batteries, and then the first clamping jaw 32 is used to clamp the upper battery of the defective battery and move upward to facilitate the removal of the defective battery.

[0042] In summary, in the battery stack secondary assembly device of the present application, the fixing component 1 can fix the entire battery stack in the accommodating space 14, the positioning component 2 can move the separation component 3 to the position of the defective battery, the separation component 3 can move all the batteries above the defective battery upward, thereby exposing the defective battery for taking out the defective battery, and finally the battery stack with the defective battery removed is re-pressed by the pressing component 4. The overall device realizes the semi-automatic removal of defective batteries from the battery stack, and integrates the pressing component 4, which can be directly pressed after the defective batteries are removed, reducing the process of recombining and fixing a part of the batteries after the defective batteries are removed, and improving the assembly efficiency of replacing defective batteries.

[0043] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
