DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the figure, a nickel mesh cutting device for lithium-ion battery production includes a base plate 1, a special-shaped wedge 2 is fixed to the upper surface of the base plate 1, one side of the special-shaped wedge 2 is a conical structure 201 extending horizontally outward, and the nickel mesh 13 can be placed horizontally on the surface of the special-shaped wedge 2, and the two corners 15 of the nickel mesh 13 can extend to the outside of the conical structure 201. Since the middle part of the special-shaped wedge 2 extends outward to form the conical structure 201, after the nickel mesh 13 is placed on the surface of the special-shaped wedge 2, the front end corner 15 of the nickel mesh 13 can be located outside the conical structure 201 and is in a suspended state.

[0020] A left cutter 3 and a right cutter 4 which can be raised and lowered vertically are provided above the bottom plate 1. The left cutter 3 and the right cutter 4 are symmetrically distributed relative to the center of the conical structure 201 of the special-shaped wedge block 2. When the left cutter 3 and the right cutter 4 move downward, they can cut the corners 15 of the nickel mesh 13 extending to the outside of the conical structure 201.

[0021] Two vertically arranged left connecting plates 5 and right connecting plates 8 are installed above the base plate 1, which are symmetrical with respect to the center of the conical structure 201 of the special-shaped wedge block 2. The surfaces of the left connecting plate 5 and the right connecting plate 8 are installed with vertical guide rails, and sliders are slidably connected to the guide rails. The left cutter 3 is fixed on the slider surface corresponding to the left connecting plate 5, and the right cutter 4 is fixed on the slider surface corresponding to the right connecting plate 8. The structure of the guide rails and the sliders belongs to the conventional linear guide rail structure in the prior art. The main purpose is to make the left cutter 3 and the right cutter 4 always move in the vertical direction during operation, so as to ensure the accuracy of the two when moving up and down, and ensure the consistency of cutting the corners 15 of the nickel mesh 13 each time.

[0022] A vertically arranged rear connecting plate 7 is fixed on the bottom plate 1, and the rear connecting plate 7 is located in the middle of the left connecting plate 5 and the right connecting plate 8. A vertically arranged guide rail is installed on the surface of the rear connecting plate 7, and a slider is slidably connected to the guide rail. A lifting block 6 is connected to the surface of the slider. The two sides of the lifting block 6 are respectively connected to the left cutter 3 and the right cutter 4 by bolts. When the lifting block 6 is lifted or lowered, it can drive the left cutter 3 and the right cutter 4 to lift or lower at the same time, that is, the left cutter 3 and the right cutter 4 can move in the vertical direction under the drive of the lifting block 6, which has the advantages of simple and reliable operation.

[0023] A top plate is provided above the bottom plate 1, and a left connecting plate 5, a right connecting plate 8 and a rear connecting plate 7 are located between the bottom plate 1 and the top plate. A driving member for driving the lifting block 6 to move up and down is fixed above the top plate. In this example, the driving member is a cylinder 11, and the end of the telescopic rod of the cylinder 11 is connected to the lifting block 6 to realize the up and down movement of the lifting block 6, the left cutter 3 and the right cutter 4.

[0024] The surface of the special-shaped wedge block 2 has a groove 202 with an arc-shaped cross section, and the root of the groove 202 has a limiting step for limiting the position of the nickel mesh 13, such as Figure 4 As shown, it is a three-dimensional view of the nickel mesh 13 spot-welded to the core rod 14, and its end position is a disc-shaped cover plate 12. The purpose of setting the groove 202 is to match the size of the circular cover plate 12. In this example, there are two grooves 202, so as to adapt to the placement of cover plates 12 of different diameters. When the cover plate 12 is placed, the outer wall of the cover plate 12 fits with the groove 202, and the center line of the cover plate 12 is in a horizontal state. The lower surface of the front nickel mesh 13 contacts the upper surface of the conical structure 201. More specifically, there are two limiting steps in this example, namely the first limiting step 203 and the second limiting step 204. The purpose is to use the limiting steps to limit the axial position of the cover plate 12. When the cover plate 12 contacts the limiting steps, it reaches the placement area. At this time, the left cutter 3 and the right cutter 4 can be used to cut the corners 15 of the nickel mesh 13.

[0025] The upper surface of the bottom plate 1 is provided with an adjustment component for fine-tuning the positions of the left connecting plate 5 and the right connecting plate 8. Specifically, Figure 2 As shown, a fixing block 10 is provided on the back of the left connecting plate 5 and the right connecting plate 8, and the fixing block 10 is fixed to the surface of the base plate 1. A horizontal and through threaded hole 9 is opened in the middle position of the fixing block 10, and a bolt can be inserted into the threaded hole 9. The end of the bolt can abut against the back of the left connecting plate 5 and the right connecting plate 8, so that in the process of assembling the left connecting plate 5 and the right connecting plate 8 to the base plate 1, the position of the two connecting plates can be fine-tuned by rotating the bolt, and then the position of the left cutter 3 and the right cutter 4 can be fine-tuned.

[0026] When the nickel mesh 13 cutting device for lithium-ion battery production is used, a workpiece (such as a nickel mesh 13, a core rod 14 and a cover plate 12) is cut into a Figure 4 As shown in the figure, the nickel mesh 13 is placed on the surface of the special-shaped wedge 2. After it is placed in place, the cylinder 11 is started, and the telescopic rod of the cylinder 11 drives the lifting block 6 to move. The lifting block 6 also drives the left cutter 3 and the right cutter 4 to move downward, thereby cutting the two corners 15 of the nickel mesh 13 to complete the cutting operation.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
