Description

Technical Field

[0001] The utility model relates to the technical field of tab cutting, and more specifically, to a lithium battery tab cutting device. Background Art

[0002] The lithium battery of a new energy vehicle is a rechargeable battery with lithium ions as the energy carrier. Its working principle is based on the insertion and extraction of lithium ions between the positive and negative electrodes. When producing and processing the lithium battery of a new energy vehicle, it involves multiple links, including the tab cutting process.

[0003] The tab is an important component of the lithium battery. The battery has positive and negative electrodes. The tab is a metal conductor that leads out the positive and negative electrodes from the battery cell. Simply put, the tab is a metal strip connecting the positive and negative electrodes of the battery cell. The cutting quality and precision of the tab have an important impact on the performance and safety of the battery.

[0004] For the existing lithium battery tab cutting device, usually the tab is placed in the cutting area and then cut by a blade. During the cutting process, since the tab is not fixed, the tab is prone to displacement during cutting, affecting the cutting effect. And the tool is prone to shaking and misalignment during cutting, resulting in a poor cutting effect. In addition, due to the impact force of the blade on the tab during cutting, the periphery of the cutting part of the tab is prone to deformation under force, affecting the quality of the tab. In view of this, we propose a lithium battery tab cutting device. Summary of the Utility Model

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A lithium battery tab cutting device, comprising a cutting tool assembly 1 and a positioning component 2;

[0029] Specifically, the cutting tool assembly 1 includes a bottom plate 101. A switch 303 is provided on the side wall of the bottom plate 101. A limit block 103, a back plate 104, and two sliding columns 107 are welded to the top surface of the bottom plate 101. The limit block 103 plays a role in limiting the downward pressure of the tool holder 109. A top plate 105 is welded to the top surface of the back plate 104. A hydraulic motor 106 is provided on the top surface of the top plate 105. The power output end of the switch 303 is electrically connected to the hydraulic motor 105. The output end of the hydraulic motor 105 is connected to a hydraulic rod 115. The bottom of the hydraulic rod 115 is screwed to the tool holder 109. A limit plate 110 is welded to the side wall of the tool holder 109. The limit plates 110 are distributed on the two side walls symmetrical to the tool holder 109. The limit plates 110 are respectively sleeved on the two sliding columns 107, playing a role in positioning during the downward pressing and cutting process of the tool holder 109 to prevent shaking, making the blade 112 more accurate when cutting the lithium battery tab. Two clamping blocks 108 are welded to the other side wall of the tool holder 109. The clamping blocks 108 are in the shape of the number "7". The clamping blocks 108 are stuck on the side wall of the back plate 104, restricting the downward movement of the tool holder 109 to the vertical direction, not shaking during cutting, with stronger stability and more accurate cutting. A fixing plate 111 and a blade 112 are screwed to the other side wall of the tool holder 109. Two springs 113 are welded to the bottom of the fixing plate 111. The function of the springs 113 is that after the pressing plate 114 presses the lithium battery tab, the tool holder 109 can continue to press down, driving the blade 112 to complete the cutting work of the lithium battery tab. The bottom of the springs 113 is welded to the pressing plate 114. By controlling the operation of the hydraulic motor 106 through the switch 303, the hydraulic rod 115 is driven to press downwards, pushing the tool holder 109 to move downwards. During the movement, the pressing plate 114 first contacts the lithium battery tab on the top surface of the placement table 201, pressing the tab near the cutting part of the lithium battery tab. Further, the tool holder 109 continues to press down, driving the blade 112 to cut the lithium battery tab until the bottom of the tool holder 109 presses on the top surface of the limit block 103, completing the cutting work of the lithium battery tab;

[0030] Further, the positioning component 2 includes a placement table 201 welded to the top surface of the bottom plate 101. Two fixing frames 203 are welded to the top surface of the placement table 201. Two push plates 204 are arranged on the top surface of the placement table 201. A threaded rod 205 penetrates through the side wall of the fixing frame 203, and a threaded hole matching the threaded rod 205 is formed in the side wall of the fixing frame 203, facilitating the rotation of the threaded rod 205 and moving along the direction of the threaded rod 205 in the threaded hole of the fixing frame 203. A rotating bearing 206 is welded to the end of the threaded rod 205, and the side wall of the rotating bearing 206 is welded to the side wall of the push plate 204. The rotating bearing 206 ensures that the push plate 204 does not rotate along with the threaded rod 205 when being pushed by the threaded rod 205. Two sliders 207 are welded to the bottom of the push plate 204, and two sliding grooves 202 matching the sliders 207 are formed on the top surface of the placement table 201. According to the width of the lithium battery tab, by rotating the threaded rod 205 to drive the push plate 204 to move, the distance between the two groups of push plates 204 is adjusted to a width suitable for the lithium battery tab, so as to perform regional positioning on the lithium battery tab. Then, the lithium battery tab is placed on the placement table 201 between the two groups of push plates 204, making the cutting of the lithium battery tab accurate.

[0031] It is worth noting that, for the convenience of cleaning the waste after the lithium battery tab is cut, a waste opening 102 is formed on the top surface of the bottom plate 101, and the side wall of the limiting block 103 is in a slope shape, and the bottom of the slope corresponds to the waste opening 102.

[0032] It should be noted that, for the structural stability of the hydraulic motor 106, a motor base is connected to the bottom of the hydraulic motor 106, and the bottom of the motor base is screwed to the top surface of the top plate 105, and the hydraulic rod 115 penetrates through the top plate 105.

[0033] In addition, in order that the pressing plate 114 does not scratch the surface of the lithium battery tab when pressing it, the pressing plate 114 is made of steel, and a plurality of square holes are formed in the pressing plate 114 from top to bottom, and a rubber pad 116 is connected to the bottom of the pressing plate 114.

[0034] Finally, for the stability of the bottom of the device, four column legs 301 are welded to the bottom of the bottom plate 101, and a cross column 302 is welded to the side wall of the column leg 301.

[0035] The circuits, electronic components and modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either.

[0036] The models of the devices or equipment involved in this article are as follows:

[0037] The model of the hydraulic motor 106 is: C05-43B0.

[0038] Working principle: When the device needs to work, according to the width of the lithium battery tab, the push plate 204 is driven to move by rotating the threaded rod 205, and the distance between the two push plates 204 is adjusted to a width suitable for the lithium battery tab to perform regional positioning on the lithium battery tab. Then, the lithium battery tab is placed on the placement table 201 between the two push plates 204. The hydraulic motor 106 is controlled to work through the switch 303, driving the hydraulic rod 115 to press downward, pushing the tool holder 109 to move downward. During the movement, the pressing plate 114 first contacts the lithium battery tab on the top surface of the placement table 201, pressing the tab near the cutting part of the lithium battery tab. Further, the tool holder 109 continues to press downward, driving the blade 112 to cut the lithium battery tab until the bottom of the tool holder 109 presses on the top surface of the limit block 103, completing the cutting work of the lithium battery tab.
