Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery electrode production equipment, and in particular to a cutting device for lithium battery electrodes. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution. With the development of microelectronics technology in the 20th century, miniaturized devices have become increasingly common, placing high demands on power supplies. As a result, lithium-ion batteries have entered a stage of large-scale practical application. The electrode sheet is the core of the lithium-ion battery. In the electrode sheet production process, it is processed through stirring, coating, drying, rolling, and cutting steps. Among these, cutting is done by cutting a whole wide electrode sheet into multiple electrode sheets of the required width using a cutting device, which facilitates subsequent battery assembly. With the advancement of technology, laser cutting of wide electrode sheets is now more commonly used.

[0003] A lithium-ion power battery electrode cutting device with publication number CN214705979U relates to the field of electrode processing technology. It includes a worktable, a cutting component, and a dust collection component. The dust collection component is located below the worktable and is used to remove dust from the worktable. This device can cut the incoming electrode material into the designed size by setting the cutting component. It solves the problem that the dust generated during electrode cutting will adhere to the electrode or remain on the worktable. The dust remaining on the worktable will then adhere to the next electrode, causing additional workload for cleaning in the subsequent electrode production process. However, during the cutting process, the electrode is prone to warping and bending, which can lead to electrode cutting deviation, more burrs, or damage to the electrode, which is not conducive to the subsequent production of lithium batteries.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figure 1-4 As shown, a lithium battery electrode cutting device of the present invention includes: a frame 1, on which a placement plate 2 is provided; a first drive assembly 3 connected to the frame 1; a second drive assembly 4 connected to the first drive assembly 3, and a lifting assembly 5 connected to one side of the second drive assembly 4; a cutting head 6 connected to one side of the lifting assembly 5; an adsorption assembly 7 connected to the placement plate 2; and a pressing assembly 8 connected below the first drive assembly 3. The adsorption assembly 7 includes a first adsorption plate 71 and a second adsorption plate 72. The first adsorption plate 71 is disposed at one end of the placement plate 2, and the second adsorption plate 72 is disposed at the other end of the placement plate 2. Both the first adsorption plate 71 and the second adsorption plate 72 are provided with multiple adsorption holes 73. The adsorption holes 73 are connected to a negative pressure pump box 75 through a suction pipe 74. A dust collection assembly 9 is detachably connected to the cutting head 6. A control box 10 is provided on one side of the frame 1, and a control panel 11 is provided on the control box 10.

[0027] In this embodiment, the electrode to be cut is placed on the placement plate 2, and the device is controlled by the control panel 11. The negative pressure pump box 75 operates, and the suction pipe 74 can evacuate the multiple suction holes 73 on the first suction plate 71 and the second suction plate 72, so that a slight negative pressure is formed inside the suction holes 73, which can adsorb the electrode above it. The slight negative pressure can prevent the electrode from tilting, making the electrode flatter during cutting and allowing the electrode to be cut more accurately.

[0028] like Figure 1 and Figure 2As shown, specifically, the first drive assembly 3 includes a first moving frame 31 and a first toothed plate 32. The first toothed plate 32 is connected to both sides of the frame 1. A first drive motor 33 is provided at both ends of the first moving frame 31. A first drive wheel 34 adapted to the first toothed plate 32 is connected to the first drive motor 33. The second drive assembly 4 includes a second moving frame 41 and a second toothed plate 42. The second toothed plate 42 is connected to the first moving frame 31. A second drive motor 43 is provided on the second moving frame 41. A second drive wheel 44 adapted to the second toothed plate 42 is connected to the second drive motor 43. By controlling the first drive motor 33 to work, the first drive wheel 34 is driven to rotate, so that the first drive wheel 34 can move back and forth on the first toothed plate 32, thereby driving the second drive assembly 4 and the cutting head 6 to move back and forth. By the second drive motor 43 to work, the second drive wheel 44 can be driven to rotate, so that the second drive wheel 44 can move left and right on the second toothed plate 42, thereby driving the cutting head 6 to move left and right. This enables the cutting head 6 to move in all directions, enhancing the cutting range and improving the cutting effect.

[0029] like Figure 1 and Figure 2 As shown, specifically, the lifting assembly 5 includes a fixed frame 51, which is connected to the second movable frame 41. A first electric telescopic rod 52 is provided on the fixed frame 51. The first electric telescopic rod 52 is connected to one side of the connecting plate 53, and the other side of the connecting plate 53 is connected to the cutting head 6. By controlling the operation of the first electric telescopic rod 52, the connecting plate 53 and the cutting head 6 can be lifted and lowered, which facilitates the adjustment of the height of the cutting head 6.

[0030] like Figure 1 and Figure 3 As shown, specifically, the extrusion assembly 8 includes a second electric telescopic rod 81, which is connected below the first moving frame 31. An extrusion plate 82 is connected below the second electric telescopic rod 81. By controlling the operation of the second electric telescopic rod 81, the extrusion plate 82 can be driven to descend and extrude the electrode sheet placed above the placement plate 2, thus preventing movement during cutting and enhancing the stability during cutting.

[0031] like Figure 1 and Figure 2 As shown, specifically, the dust collection component 9 includes a dust collection hood 91, which is fitted over the outside of the cutting head 6. A dust collection pipe 92 is connected to one side of the dust collection hood 91, and the dust collection pipe 92 is connected to the dust collector 94 through a dust extraction pipe 93. By controlling the operation of the dust collector 94, air can be extracted from the dust collection hood 91 through the dust extraction pipe 93 and the dust collection pipe 92. This continuously removes the debris generated during the cutting process of the cutting head 6 as it moves, preventing debris from splashing and polluting the environment.

[0032] like Figure 1 and Figure 2As shown, specifically, the frame 1 is provided with a first limiting slide plate 12 on both sides, and the first moving frame 31 is provided with a second limiting slide plate 13 on one side; the first limiting slide plate 12 can limit the first moving frame 31, and the second limiting slide plate 13 can limit the second drive component 4 and the lifting component 5, thereby enhancing the stability of the first drive component 3 and the second drive component 4 when they move.

[0033] Working principle: The operator places the electrode to be cut on the placement plate 2 and operates the device through the control panel 11. The negative pressure pump box 75 operates, and the air is drawn through the air extraction pipe 74 to the multiple adsorption holes 73 on the first adsorption plate 71 and the second adsorption plate 72, so that a slight negative pressure is formed inside the adsorption holes 73, which can adsorb the electrode above it. The slight negative pressure can prevent the electrode from tilting, making the electrode flatter during cutting and allowing for more precise cutting.
