Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery diaphragm processing, and in particular relates to a cutting device for lithium battery processing. Background Art

[0002] Lithium batteries are rechargeable batteries that are widely used in various portable electronic devices (such as mobile phones and laptops), electric vehicles, energy storage systems, and other fields requiring portable or renewable energy sources due to their high energy density, long cycle life, and low self-discharge rate. Their main function is to store and supply electrical energy, allowing these devices to operate without a direct power connection. In the lithium battery processing process, cutting equipment is a key link, especially for the processing of the diaphragm. The diaphragm is a thin film located between the positive and negative electrodes of the lithium battery, which acts as an insulator and allows lithium ions to pass through, and is crucial to the safety and performance of the battery. Cutting equipment is generally used to cut the diaphragm material into the required size and shape for subsequent assembly into battery cells. Existing cutting equipment for lithium battery processing uses multiple cutting knives to cut the lithium battery diaphragm during transportation. However, the spacing between the multiple cutting knives is fixed and cannot be adjusted. Therefore, it can only cut lithium battery diaphragms of specific sizes, and cannot cut lithium battery diaphragms of different sizes, which has the disadvantage of poor flexibility.

[0003] For example, the utility model with announcement number CN215548844U discloses a leveling and cutting device for processing lithium battery separators. In this patent solution, when it is necessary to cut out lithium battery separators of different specifications, the spacing between the multiple cutting slices used to cut the lithium battery separators is fixed and cannot be adjusted, and lithium battery separators of different specifications cannot be cut out, which limits the cutting equipment's response to the demand for diversified products and greatly reduces the flexibility of the cutting equipment. Utility Model Content

[0004] In view of this, the utility model addresses the shortcomings of the existing technology and provides a cutting device for lithium battery processing, which can quickly adjust the spacing between the cutting blades, can quickly adapt to the production needs of cutting lithium battery diaphragms of different specifications, improve the variability of the cutting equipment, and also greatly improve the flexibility of the cutting equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cutting device for lithium battery processing, comprising a workbench, a connecting plate is provided at the upper end of the workbench, two sliding plates corresponding to the front and rear positions are slidingly provided inside the connecting plate, the lower ends of the two sliding plates are provided with cavity blocks, cutting knives are slidably provided inside the two cavity blocks, an adjustment mechanism for adjusting the cutting spacing of the two cutting knives is provided at the upper end of the inner part of the connecting plate, a quick-change mechanism for quickly replacing the cutting knives is provided on the right side of the two cavity blocks, the adjustment mechanism includes a bidirectional screw rod rotatably provided at the upper end of the inner part of the connecting plate, the two sliding plates are respectively threadedly connected to the front and rear corresponding ends of the bidirectional screw rod, and a second motor is provided on the rear side of the connecting plate, and the output shaft of the second motor is connected to the rear end of the bidirectional screw rod through a coupling.

[0006] As a further improvement of the present invention, two support plates 1 are provided on the left side of the upper end of the workbench, and the interiors of the two support plates 1 are provided with mounting disk 1 which is rotated by rotating shaft 1. Two support plates 2 are provided on the upper right end of the workbench, and the interiors of the two support plates 2 are provided with mounting disk 2 which is rotated by rotating shaft 2. A motor 1 is provided at the rear end of the rear support plate 2, and the output shaft of the motor 1 is connected to the rear end of the rear rotating shaft through a coupling. Two limiting rollers corresponding to the left and right positions are rotatably provided on the upper end of the workbench.

[0007] As a further improvement of the present invention, the quick-change mechanism includes locking columns that are slidably arranged inside the two cavity blocks respectively, locking holes are opened inside the right sides of the two cutting knives, the two locking columns are respectively plugged into adjacent locking holes, and pull plates are provided on the right sides of the two locking columns. Springs are provided between the cavity blocks and the pull plates, and the two springs are respectively mounted on the outer arc surfaces of the corresponding locking columns.

[0008] As a further improvement of the present invention, a control panel is provided on the front side of the workbench, and both motor 1 and motor 2 are electrically connected to the control panel.

[0009] As a further improvement of the present invention, a support frame is welded and fixed to the lower end of the workbench, and a plurality of mounting holes are provided inside the support frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] First, the cutting device is fixed in a suitable position through the mounting holes inside the support frame to avoid displacement during operation of the cutting device, making the operation of the cutting device more stable.

[0012] Secondly, the lithium battery diaphragm roller that needs to be cut is installed between the two mounting disks 1 by bolts, and the winding roller is installed between the two mounting disks 1 by bolts. Then the lithium battery diaphragm is passed through the lower end of the limiting roller on the left, and through the lower end of the cutting knife and out of the lower end of the limiting roller on the right, and fixed on the winding roller. Then, the control panel is used to turn on the motor 1, and the output shaft drives the mounting disk 2 on the rotating shaft 2 to rotate, so that the rotation of the winding roller drives the lithium battery diaphragm to move and cooperate with the cutting knife to quickly cut the lithium battery diaphragm.

[0013] Thirdly, by controlling the control panel to turn on the second motor, the output shaft drives the bidirectional screw to rotate, which can make the cutting knives on the sliding plates on both sides move closer or farther away from each other, thereby realizing the adjustment of the spacing of the cutting knives. The cutting knife spacing can be adjusted quickly, which can quickly adapt to the production needs of lithium battery diaphragm cutting of different specifications, improve the variability of the cutting equipment, and also greatly improve the flexibility of the cutting equipment.

[0014] Fourth, by pulling the pull plate, the locking post moves out of the locking hole. The spring is now in a stretched state, and the old cutter is then slid out of the cavity frame. The new cutter is then slid into the cavity frame, aligning the locking holes. The pull plate is then released. The spring then quickly rebounds, driving the locking post into the locking hole. This allows for quick replacement of worn cutters, making it more convenient for operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 、 2 As shown, the adjustment mechanism includes a bidirectional screw rod 202 rotatably arranged at the upper end of the inner part of the connecting plate 110, and two sliding plates 111 are respectively threadedly connected to the front and rear corresponding ends of the bidirectional screw rod 202.

Then the lithium battery diaphragm is passed through the lower end of the limiting roller 106 on the left, and passes through the lower end of the cutting knife 112 and out of the lower end of the limiting roller 106 on the right, and fixed on the winding roller.
