[0037] like Figure 1-Figure 7 As shown, this embodiment provides a film-tearing tool 100 for tearing off the insulating film 300 on the battery 200 with unqualified film coating, so as to re-film the battery 200 with the insulating film 300 torn off. The film-tearing tool 100 has a simple structure, fewer film-tearing steps and is easy to operate, which can improve the efficiency of film-tearing.

[0038] Among them, the film tearing tool 100 includes a placement seat 2, a clamping component 3 and a pushing component 4. The placement seat 2 is fixedly arranged, and the placement seat 2 is used to place the battery 200 to be torn off. The clamping component 3 can clamp the torn end of the insulating film 300 covered on the battery 200 to be torn off on the placement seat 2. The pushing component 4 includes a pushing seat 41, and the pushing seat 41 can be movably arranged relative to the placement seat 2. The pushing seat 41 can push the battery 200 to be torn off the placement seat 2 to tear off the insulating film 300 from the battery 200. Before tearing the film, first tear off one end of the insulating film 300 coated on the battery 200 to be torn off to form a torn end of the insulating film 300, then place the battery 200 with one end of the torn insulating film 300 in the placement seat 2, and then use the clamping seat 31 to clamp the torn end of the insulating film 300 on the placement seat 2, and push the battery 200 to be torn off the placement seat 2 through the pushing seat 41, so that the insulating film 300 and the battery 200 are separated, and the purpose of tearing the film is achieved. The film tearing tool 100 has a simple structure, easy operation, low manufacturing cost, high film tearing efficiency, and the insulating film 300 is uniformly stressed under the clamping of the clamping seat 31, the film tearing effect is good, and there is less residual glue, which is convenient for cleaning the battery 200 after the film is torn off and then re-wrapping.

[0039] like Figure 1 As shown, the film tearing tool 100 also includes a bracket 1, a placement seat 2 is fixedly installed on the bracket 1, and the bracket 1 is fixedly arranged.

[0040] like Figure 2 As shown, the push-off assembly 4 also includes a power source 42, which is fixedly arranged relative to the placement seat 2, and the power source 42 can drive the push seat 41 to move. Specifically, the output end 421 of the power source 42 is connected to the push seat 41, and the output end 421 of the power source 42 can move along the length direction of the battery 200 to be torn off. The output end 421 of the power source 42 drives the push seat 41 to move along the length direction of the battery 200 to be torn off, so that the battery 200 and the insulating film 300 move relative to each other, so that the insulating film 300 and the battery 200 are separated, and the purpose of tearing off the film is achieved.

[0041] In this embodiment, the power source 42 can be a cylinder, and the cylinder is fixedly arranged relative to the placement seat 2.

[0042] Furthermore, the push-off assembly 4 also includes a mounting seat 44 , and the cylinder is fixedly mounted on the mounting seat 44 , and the mounting seat 44 is fixedly arranged relative to the placement seat 2 .

[0043] Specifically, the mounting seat 44 is fixedly mounted below the bracket 1 , and the cylinder is fixedly mounted on the mounting seat 44 .

[0044] In other embodiments, the power source 42 may also be other linear mechanisms, such as a screw-nut mechanism, a connecting rod-slider mechanism, a gear-rack mechanism, etc., without limitation, as long as it can push the push seat 41 to move along the length direction of the battery 200.

[0045] Furthermore, the push-off assembly 4 further includes a solenoid valve 43, which can control the inlet and outlet of the gas source of the cylinder. The solenoid valve 43 controls the inlet and outlet of the gas source of the cylinder, thereby controlling the extension and contraction of the output end 421 of the cylinder, thereby driving the push seat 41 to move, so as to perform the film tearing action.

[0046] Specifically, the battery 200 is mounted on the bracket 1 .

[0047] like Figure 1-Figure 3 As shown, the clamping assembly 3 includes a clamping seat 31, and the clamping seat 31 has a clamping area, the shape of which is adapted to the shape of the torn end of the insulating film 300, and the shape of the clamping area is also adapted to the shape of the placement seat 2. Such a configuration allows the clamping seat 31 to clamp the insulating film 300 with uniform force, a good film tearing effect, less residual glue, and facilitates cleaning of the torn battery 200 and then re-wrapping.

[0048] Furthermore, the clamping area is an inner inclined surface 311, and the placement seat 2 has an outer inclined surface 221, and the inner inclined surface 311 and the outer inclined surface 221 are adapted to clamp the torn end of the insulating film 300 between the inner inclined surface 311 and the outer inclined surface 221. The matching arrangement of the inner inclined surface 311 and the outer inclined surface 221 makes the clamping of the insulating film 300 more stable, reducing the risk of the insulating film 300 detaching from the clamping seat 31 during the film tearing process.

[0049] Furthermore, along the moving direction of the push seat 41, the outer inclined surface 221 gradually tilts away from the battery 200 to be torn off. In other words, the moving direction of the push seat 41 is the length direction of the battery 200, and along the moving direction of the push seat 41, the inner inclined surface 311 also gradually tilts away from the battery 200 to be torn off. Such an inclined direction makes the size of both inclined surfaces gradually increase along the moving direction of the push seat 41. In the process of the push seat 41 pushing the battery 200, the clamping seat 31 is not easy to fall off from the placement seat 2, ensuring that the clamping of the insulating film 300 is more stable, so that the film can be torn off smoothly.

[0050] like Figure 4 As shown, the placement seat 2 is provided with a placement groove 21 for placing the battery 200 to be peeled, and the placement groove 21 is provided with an opening 24, the direction of the opening 24 being perpendicular to the moving direction of the push seat 41. The opening 24 is provided to facilitate placing the battery 200 into the placement groove 21.

[0051] Furthermore, a movable hole 11 is opened on the bracket 1, and the push seat 41 can enter the placement groove 21 through the movable hole 11 and push the battery 200 to move along the length direction of the battery 200, so as to separate the battery 200 and the insulating film 300.

[0052] Furthermore, the push seat 41 can abut against the battery 200 to be torn off. After the insulating film 300 is torn off from the battery 200, most or all of the battery 200 is pushed out of the placement slot 21, and the push seat 41 can automatically return to the movable hole 11 under the action of the power source 42, so as to perform the next film tearing. The abutment connection between the push seat 41 and the battery 200 is simple and easy to operate, and will not affect the film tearing process.

[0053] It should be noted that after the insulating film 300 is torn off the battery 200 and most of the battery 200 is pushed out of the placement slot 21 , the battery 200 can also be taken out of the placement slot 21 manually.

[0054] In other embodiments, the clamping assembly 3 may further include a plurality of clamping seats 31, which are arranged at intervals along the circumference of the torn end of the insulating film 300, and the plurality of clamping seats 31 clamp the torn end of the insulating film 300 on the placement seat 2, thereby ensuring the stable clamping of the insulating film 300. The specific shape and structure of the plurality of clamping seats 31 are not limited, and may be structures such as clamping claws, as long as the clamping stability of the insulating film 300 by the clamping assembly 3 can be ensured.

[0055] Furthermore, the placement seat 2 includes an integrally formed clamping portion 22 and a placement portion 23 , the placement portion 23 is fixedly mounted on the bracket 1 , the clamping portion 22 is provided with the outer inclined surface 221 , and the clamping area of ​​the clamping seat 31 is clamped on the clamping portion 22 .

[0056] like Figure 5-Figure 7 As shown, the battery 200 may be a square battery 200, and the battery 200 includes four side surfaces, namely, a main side surface 204, a first side surface 201, a second side surface 202 and a third side surface 203, and two end surfaces. The main side surface 204 is provided with a cover plate and a pole and other main components. The main side surface 204 is arranged opposite to the second side surface 202, and the first side surface 201 and the third side surface 203 are arranged opposite to each other. The insulating film 300 coated on the battery 200 generally coats the three side surfaces, namely, the first side surface 201, the second side surface 202 and the third side surface 203, and the two end surfaces of the battery 200, and the main side surface 204 of the battery 200 is not coated. Of course, the battery 200 may also be in other shapes, and the placement groove 21 may also be adjusted according to the shape of the battery 200, which is not limited thereto.

[0057] After the film coating is completed, the insulating film 300 forms an overlapped portion on one of the end faces of the battery 200. In the film tearing process, the overlapped portion is firstly torn off manually to form the torn end of the insulating film 300, and then the battery 200 with the torn insulating film 300 is placed in the placement groove 21. When the battery 200 is placed, the end face of the battery 200 without the torn end of the insulating film 300 abuts against the push seat 41, and the main side surface 204 is exposed from the opening 24 of the placement groove 21. Then, the torn end of the insulating film 300 is clamped between the inner inclined surface 311 and the outer inclined surface 221 by the clamping seat 31, and then, the solenoid valve 43 is operated so that the output end 421 of the power source 42 drives the push seat 41 to move, and then the battery 200 is gradually pushed away from the placement groove 21, so that the battery 200 and the insulating film 300 move relative to each other, so that the insulating film 300 and the battery 200 are separated, and the purpose of film tearing is achieved.

[0058] In order to make the shape of the clamping area better adaptable to the shape of the torn end of the insulating film 300 and the shape of the clamping portion 22, the shape of the torn end of the insulating film 300 is the shape of three sequentially connected first side surfaces 201, second side surfaces 202 and third side surfaces 203, and the clamping portion 22 is also correspondingly arranged as three sequentially connected outer inclined surfaces 221, the clamping seat 31 is arranged in a U-shape, and the inner inclined surface 311 of the clamping seat 31 is also three sequentially connected inclined surfaces, so as to clamp the torn end of the insulating film 300 and make the force on the insulating film 300 uniform, which makes it easier to completely tear the insulating film 300 off the battery 200, with good film tearing effect and less residual glue, and it is convenient to clean the battery 200 after the film is torn and then re-wrap it.

[0059] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
