Description

Technical Field

[0001] This application relates to the field of battery electrode sheet cutting dies, and particularly to a pressure plate device for a battery electrode sheet cutting die. Background Art

[0002] In the production process of lithium batteries, electrode sheet cutting is an indispensable key link. In the traditional battery electrode sheet cutting die during the cutting process, the pressure plate is usually fixedly arranged at the bottom of the lower template, used to fix the electrode sheet material during cutting to prevent it from moving or deforming during cutting. However, this fixed design is prone to interfering with subsequent cleaning operations after cutting. Especially when it is necessary to clean the upper cutting knife and its surrounding cleaning parts, the presence of the pressure plate will greatly increase the cleaning difficulty and cleaning time, thereby affecting the overall production efficiency.

[0003] In response to the above problems, the industry has tried to improve the design of the pressure plate to reduce the cleaning difficulty and improve the production efficiency. For example, some designs use a detachable pressure plate, but this method also takes a lot of time during the disassembly and installation process, and frequent disassembly may lead to a decrease in the matching accuracy between the pressure plate and the lower template. Utility Model Content

[0004] The purpose of this application is to provide a pressure plate device for a battery electrode sheet cutting die, which is provided with an avoidance lateral movement driving device that can drive the pressure plate to automatically move away from the upper cutting knife after cutting, so as to avoid interfering with the cleaning part.

[0005] To achieve the above purpose, this application provides the following technical solutions:

[0006] A pressure plate device for a battery electrode sheet cutting die, including a pressure plate arranged at the bottom of the lower template and an avoidance lateral movement driving device, and the avoidance lateral movement driving device can drive the pressure plate to move away from the upper cutting knife to avoid interfering with the cleaning part.

[0007] Further, the avoidance lateral movement driving device includes a lateral movement driving cylinder, a lateral movement guide rail and a lateral movement connecting seat. The lateral movement connecting seat is installed at the bottom of the upper template through the lateral movement guide rail. The pressure plate is installed below the lateral movement connecting seat, and the lateral movement driving cylinder drives the pressure plate to move away from or close to the upper cutting knife along the lateral movement guide rail through the lateral movement connecting seat.

[0008] Further, a support plate is also arranged on the lower template, and the support plate is arranged on one side of the upper cutting knife.

[0009] Further, knife-relying blocks are respectively arranged on both sides of the lower template.

[0010] The beneficial effects of this application are:

[0011] The present application is provided with an avoidance and transverse movement driving device, which can drive the pressure plate to automatically move away from the upper cutting knife after cutting, so as to avoid interfering with the cleaning part. This design not only simplifies the cleaning process, improves the cleaning efficiency, but also reduces the equipment wear and maintenance costs caused by inconvenient cleaning. At the same time, due to the introduction of the avoidance and transverse movement driving device, the structure of the entire cutting die is more compact and the operation is more flexible, further improving the production efficiency and product quality. Description of the Drawings

[0013] Figure 2 It is a schematic diagram when the avoidance and transverse movement driving device drives the pressure plate to move away from the upper cutting knife provided by an embodiment of the present application;

[0014] Figure 3 It is a perspective view of a battery pole piece cutting die provided by an embodiment of the present application; Detailed Embodiment

[0015] The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application. The following will describe the embodiments of the present application in detail with reference to the drawings.

[0016] As Figure 1 and Figure 2 shown, a pressure device 6 of a battery pole piece cutting die includes a pressure plate 61 arranged at the bottom of the upper template 1 and an avoidance and transverse movement driving device 62. The avoidance and transverse movement driving device 62 can drive the pressure plate 61 to move away from the upper cutting knife 4 to avoid interfering with the cleaning part 71.

[0017] As Figure 1 shown, the avoidance and transverse movement driving device 62 includes a transverse movement driving cylinder 621, a second transverse movement guide rail 622 and a transverse movement connecting seat 623. The transverse movement connecting seat 623 is installed at the bottom of the upper template 1 through the second transverse movement guide rail 622. The pressure plate 61 is installed below the transverse movement connecting seat 623. The transverse movement driving cylinder 621 drives the pressure plate 61 to move away from or close to the upper cutting knife 4 along the second transverse movement guide rail 622 through the transverse movement connecting seat 623.

[0018] As Figure 3 shown, a cutting die for automatically cleaning a cutting knife includes an upper template 1, a guide post 2, a lower template 3, an upper cutting knife 4, a lower cutting knife 5, a pressure device and a cutting knife cleaning device 7.

[0019] As Figure 3As shown, a support plate 8 is further provided on the lower template 3, and the support plate 8 is disposed on one side of the upper cutter 4. The support plate 8 provides a stable support point for the pole piece, which helps to reduce the shaking or deviation of the pole piece during operation, thereby improving the cutting accuracy and stability.

[0020] As Figure 3 shown, knife-relying blocks 9 are respectively disposed on both sides of the lower template 3. The design of the knife-relying blocks 9 provides a clear guiding path for the upper cutter 4, ensuring that the upper cutter 4 can accurately align with the cutting position during the descending process, reducing deviation and improving the cutting precision.

[0021] As Figure 3 shown, in-place sensors 726 are respectively disposed on both sides of the lower template 3. The in-place sensors 726 can monitor in real time whether the cleaning part of the cutter cleaning device 7 accurately reaches the preset position, ensuring that the cleaning operation is carried out at the correct position and avoiding problems such as incomplete cleaning or repeated cleaning caused by position deviation.
