The device uses an electric heating blade to make trimming quick and easy, and is also provided with insulating tape and a protective cover to make the entire operation process safe. In this device, after the battery cell is placed on the support plate, the insulating tape provided on the support plate is used to bond the two. However, during the trimming process, the shear force generated by the cutter can easily cause the battery cell to slide relative to the support plate, resulting in a failure in cutting the tape.

The first limit block 25 and the second limit block 26 can abut against the battery cell at the same time to limit the battery cell from sliding relative to the base 1 along the second direction, thereby ensuring the shear effect of the structural adhesive.

[0073] As an implementation method, Figure 1 As shown, the base 1 is provided with at least one second slide groove 12 along the second direction, and the second slide rod 27 is arranged in a one-to-one correspondence with the second slide groove 12.

There are two cutters 31 in the cutter assembly 3. The cutter assembly 3 also includes a sliding rod 34 and a connecting block 32. The sliding rod 34 is slidably inserted in the sliding hole. The connecting block 32 is arranged along the first direction and connected to one end of the sliding rod 34. The two cutters 31 are arranged at intervals from each other and are both connected to the connecting block 32. The movable end of the driving assembly 4 is hinged to the other end of the sliding rod 34.

[0081] The two cutters 31 are spaced apart from each other and are both connected to the connecting block 32 . The sliding rod 34 and the sliding hole play a connecting and guiding role in the sliding of the connecting block 32 and the cutters 31 relative to the fixed plate 222 .

[0082] Furthermore, the first direction, the second direction and the third direction constitute an X-axis, a Y-axis and a Z-axis in a plane rectangular coordinate system.

[0084] The guide rod 33 is used to cooperate with the sliding rod 34 to increase the sliding stability of the cutter 31 .

[0085] like Figure 1 , Figure 2As shown, the driving assembly 4 includes a fixed head 41, a sliding head 42, an elastic part 43, a connecting rod 44 and a handle 45. The fixed head 41 is spaced apart from the sliding rod 34 and fixedly connected to the fixed plate 222. The sliding head 42 is connected to the other end of the sliding rod 34. The elastic part 43 is arranged between the sliding head 42 and the fixed plate 222. One end of the elastic part 43 is connected to the sliding head 42 and the other end is connected to the fixed plate 222. An arc groove 46 is opened in the middle of the connecting rod 44. One end of the connecting rod 44 is hinged to the fixed head 41, and the middle part of the connecting rod 44 is hinged to the sliding head 42. The sliding head 42 can slide relative to the connecting rod 44 along the guide of the arc groove 46. The handle 45 is sleeved on the other end of the connecting rod 44.

[0086] The fixed head 41, the sliding head 42, the elastic part 43, the connecting rod 44 and the handle 45 form a hinged structure with the sliding rod 34. The user can drive the sliding rod 34 to slide relative to the sliding hole by pressing or lifting the other end of the connecting rod 44, thereby driving the cutter 31 to move. The structure is simple, the sliding is stable, and it can be manually operated at low cost.

[0087] Furthermore, the elastic portion 43 is a spring that is common and easy to purchase on the market. The spring is sleeved on the sliding rod 34 and is connected to the sliding head 42 and the fixed plate 222. At the same time, the connecting rod 44 is rotatably connected to the fixed head 41 and the sliding head 42 through a rotating shaft, wherein the rotating shaft arranged in the middle of the connecting rod 44 can slide along the guide of the arc slide groove 46.

[0088] The specific working process of the utility model is as follows: a clamping assembly 2 is provided on the base 1, and a clamping gap 21 is provided in the clamping assembly 2. The battery cell can be slidably inserted in the clamping gap 21 and is detachably connected to the clamping assembly 2. The cutter 31 is provided relative to the battery cell and has a first state of sliding close to the battery cell and a second state of sliding away from the battery cell. The fixed end of the driving assembly 4 is connected to the clamping assembly 2, and the movable end is connected to the cutter 31, which is used to drive the cutter 31 to slide close to or away from the battery cell relative to the clamping assembly 2. Compared with the prior art, by providing the clamping assembly 2 and the clamping gap 21, the battery cell can be slidably inserted in the clamping gap 21 and is detachably connected to the clamping assembly 2, which is convenient for installation and disassembly, and avoids bonding the battery cell to the base 1. At the same time, the movable end of the driving assembly 4 can drive the cutter 31 to move, so that the cutter 31 can slide close to the battery cell to cut off the structural glue on the battery cell.

[0089] When in use, the user first inserts the battery cell into the clamping gap 21, and makes one end of the battery cell abut against the first limit block 25 and the other end abut against the second limit block 26. At the same time, one side of the battery cell abuts against a first limit plate 221 and the other side abuts against the second limit plate 23. Here, the battery cell cannot slide relative to the base 1 in the first direction and the second direction. Then the worker holds the handle 45 and presses down the connecting rod 44. One end of the connecting rod 44 rotates relative to the fixed head 41 and pushes the sliding rod 34 to slide along the sliding hole. During the sliding process, the hinge between the sliding head 42 and the connecting rod 44 slides along the guide of the arc groove 46. Finally, the handle 45 is continuously pressed down. The sliding rod 34 drives the cutter 31 to approach and abut against the structural glue on the battery cell, and cuts the structural glue from the pole ear of the battery cell. Finally, the connecting rod 44 and the cutter 31 are lifted, and the battery cell is taken out from the clamping gap 21, waiting for the next shearing operation.

[0090] The device, through the above structure, can solve the technical problem in the prior art that the battery cell needs to be removed from the support plate after trimming, which causes inconvenience in use.

[0091] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
