[0002] Reference Figure 1 A soft-pack battery cell includes a soft-pack battery cell body 01, a tab 02, and a plastic edge 03. The tab 02 is provided at both ends of the soft-pack battery cell body 01 in the length direction, and the plastic edge 03 is provided at one end of each tab 02 away from the soft-pack battery cell body 01. After the production of the soft-pack battery cell body 01 is completed, the plastic edge 03 needs to be cut off.

[0003] OCV (Open Circuit Voltage) is an important parameter used to test batteries. Specifically, the OCV test measures the voltage value of the battery in the open circuit state, and this voltage value reflects the size of the internal electromotive force of the battery. The current OCV test operation is to electrically connect the pole ears at both ends of the soft-pack battery body. After completing the OCV test of the soft-pack battery, the operator cuts off the edge of the plastic. However, the entire test and cutting process requires more processes, and the operator needs to remove the soft-pack battery from the test mechanism and cut it. The whole process is time-consuming, resulting in reduced production efficiency of the soft-pack battery. Summary of the invention

[0042] Reference Figure 4 and Figure 6 When processing the soft-pack battery cell body 01, the soft-pack battery cell body 01 to be processed is placed above the support plate 61, and the two positioning end plates 64 and a plurality of pairs of clamping positioning blocks 63 position the soft-pack battery cell body 01 so that it corresponds to the detection station position of the detection component 2. At this time, the pole ear 02 on the soft-pack battery cell body 01 is located between the corresponding two clamping detection blocks 21. When the soft-pack battery cell body 01 is subjected to the OCV test, the two clamping detection blocks 21 approach each other under the action of the clamping cylinder 22 and clamp the pole ear 02, thereby realizing the OCV test of the soft-pack battery cell body 01. After the detection is completed, when the sliding plate 8 moves along the length direction of the central slide rail 9 under the driving action of the driving source (not shown in the attached figure), the lifting and lowering abutment rod 66 slides along the first guide rail 15. When the support frame 6 moves from the first guide section 151 to the second guide section 152, the height of the lifting plate decreases, and the top of the top support vertical rod 69 passes through the support plate 61 through the connecting hole 611. The top of the top support vertical rod 69 supports the soft-pack battery cell body 01 so that its height is set corresponding to the top surface of the abutment block 310. The two ends of the support plate 61 in the length direction move to the clearance groove 16 of the abutment block 310 during cutting, avoiding the edge of the support plate 61 from affecting the cutting of the soft-pack battery cell body 01. The setting of the support frame 6 realizes the transportation of the soft-pack battery cell body 01, which helps to speed up its processing efficiency.

[0043] Reference Figure 5 and Figure 6 , at this time, the two plastic edges 03 correspond to the two cutting components 3 one by one, and the plastic edge 03 is located between the abutment block 310 and the cutting knife 309. The cutting cylinder 303 drives the punching block 304 and the connecting bottom block 308 to move downward, and the clamping block 306 first presses the pole ear 02 on the top of the abutment block 310 to prevent the soft-pack battery cell body 01 from shaking during the cutting process. At this time, the cutting cylinder 303 continues to drive, the clamping spring 311 compresses and accumulates elastic potential energy, the sliding ring block 305 and the connecting bottom block 308 slide relative to each other, and the cutting knife 309 continues to move downward with the connecting bottom block 308 and the punching block 304 and cuts off the plastic edge 03. The cut plastic edge 03 falls into the blanking tube 11 through the first blanking port 4 and the second blanking port 5, and falls into the waste collection box 13 through the guide inclined plate 12 for collection.

[0044] Reference Figure 4 , Figure 5 and Figure 7 After the cutting is completed, the punch block 304 moves upward and lifts up, and the sliding ring block 305 is reset under the action of the compression spring 311. While cutting, the sliding plate 8 slides in the opposite direction to the end close to the detection component 2 to support and transport the soft-pack battery cell body 01 that needs to be cut in the next round. At this time, the unloading support plate 71 moves with the sliding plate 8 to the oblique lower side of the soft-board battery cell body being cut. After the cutting is completed, the unloading rack 7 slides on the central slide rail 9 along with the sliding plate 8 in the direction away from the detection component 2. Combined with Figure 1 and Figure 2 , when the unloading slide bar 76 moves from the third guide section 171 to the fourth guide section 172, the unloading support plate 71 gradually rises and contacts the bottom surface of the soft-pack battery cell body 01 that has been cut, and removes it from between the two cutting frames 301. The setting of the unloading edge 72 reduces the possibility of the soft-pack battery cell body 01 falling off the unloading support plate 71 during the unloading process. When the sliding plate 8 moves to abut against the supporting vertical plate 18, the first control switch 19 is pressed, and the unloading support plate 71 rotates under the drive of the rotating cylinder 73, and the soft-pack battery cell body 01 that has been cut is poured onto the unloading inclined plate 20, and the soft-pack battery cell body 01 falls into the finished product collection box 24 for collection. At the same time, the giving way cylinder 74 drives the unloading slide bar 76 to descend, and the unloading support plate 71 to descend, so as to prevent the unloading support plate 71 from pushing down the soft-pack battery cell body 01 that has just been transported to the cutting assembly 3 through the support frame 6 when the sliding plate 8 moves back. When the sliding plate 8 is reset to the side of the detection component 2, the second control switch 26 is pressed, the rotating cylinder 73 and the giving way cylinder 74 are started, and the unloading slide bar 76 and the unloading support plate 71 are reset to cope with the next round of unloading operation of the soft-pack battery body 01. For soft-pack battery bodies 01 of different lengths, the spacing between the two cutting frames 301 can be adjusted by the spacing adjustment component 10, which expands the application range of the device.

[0045] The implementation principle of an OCV test cutting device for a soft-pack battery cell in the embodiment of the present application is as follows: when processing the soft-pack battery cell body 01, the soft-pack battery cell body 01 to be processed is placed above the support plate 61, and the two clamping detection blocks 21 clamp the tab 02 to achieve OCV detection. After the detection is completed, the sliding plate 8 moves, and the setting of the support frame 6 realizes the transportation of the soft-pack battery cell body 01, which helps to speed up its processing efficiency. The cutting component 3 simultaneously cuts off the plastic edges 03 at both ends of the soft-pack battery cell body 01.

[0046] After the cutting is completed, the unloading rack 7 slides on the central slide rail 9 in the direction away from the detection assembly 2, and the unloading pallet 71 removes the soft-pack battery cell body 01 from between the two cutting frames 301 to realize automatic unloading. In this way, the detection, cutting, unloading and transportation processes are carried out simultaneously, thereby improving the production and processing efficiency of the soft-pack battery cell body 01.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
