Description

Technical Field

[0001] This utility model relates to the field of battery cell casing production and slitting technology, specifically a lithium battery cell casing production and slitting device. Background Technology

[0002] The battery cell casing production slitting device is a mechanical device specifically used in the battery cell casing production process to precisely slit the raw materials of the battery cell casing. It uses high-speed rotating blades or precise cutting mechanisms to slit the material longitudinally or laterally to meet the size and quality requirements of battery cell casing production.

[0003] Existing battery cell casing production slitting devices generally use a two-point clamping method to clamp the battery cell casing, which is prone to unstable clamping. Unstable clamping can cause the battery cell casing to shake or shift during the cutting process, thus affecting the cutting accuracy and dimensional consistency. Therefore, a lithium battery cell casing production slitting device is proposed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery cell casing production and slitting device. By turning on the motor, the motor drives the disc and cylinder to rotate. The cylinder drives the L-shaped plate and guide post to rotate. The guide post drives the slider and clamping plate to move until the four clamping plates simultaneously clamp the battery cell casing. This solves the problem that existing battery cell casing production and slitting devices generally use a two-point clamping method to clamp the battery cell casing, which is prone to unstable clamping. Unstable clamping can cause the battery cell casing to shake or shift during the cutting process, thus affecting the cutting accuracy and dimensional consistency.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a lithium battery cell casing production and slitting device, comprising a housing, a cutting assembly, a clamping assembly, and a dust extraction assembly. The cutting assembly includes a laser cutter and a linear module. The laser cutter is mounted on the housing, and the linear module is mounted on the top of the inner cavity of the housing. The laser head of the laser cutter is mounted on the moving part of the linear module.

[0007] The clamping assembly includes a motor and a base plate. The motor is installed in the inner cavity of the housing. A disc is set on the output shaft of the motor. A cylinder is installed on the disc. There are four sets of cylinders. An L-shaped plate is rotatably fitted on the cylinder. A guide post is installed on the L-shaped plate. A slider is rotatably fitted on the guide post. Four sets of sliding grooves are opened on the base plate. The slider slides in contact with the sliding grooves. A clamping plate is installed on the slider. A horizontal plate is installed on the base plate. The end of the horizontal plate away from the base plate is installed on the inner wall of the housing.

[0008] Furthermore, a V-shaped groove is provided on the clamping plate, and a rubber pad is provided on the V-shaped groove.

[0009] Furthermore, the clamping plate slides against the surface of the substrate, which is located directly below the linear module.

[0010] Furthermore, the vacuuming assembly includes a vacuum port, one end of which is located in the inner cavity of the housing, and the other end of which is connected to a vacuum hose that extends through the top of the housing. The end of the vacuum hose away from the vacuum port is connected to a bag vacuum cleaner, which is mounted on the housing.

[0011] Furthermore, a door is installed on the box, and the door is connected to the box via hinges.

[0012] Furthermore, a glass observation window is provided on the door, and a support frame is installed at the bottom of the container.

[0013] This utility model has the following beneficial effects:

[0014] This invention incorporates a clamping assembly in a lithium battery cell casing production and slitting device. By activating a motor, the motor drives a disc and a cylinder to rotate. The cylinder then drives an L-shaped plate and a guide post to rotate, and the guide post drives a slider and a clamping plate to move until all four clamping plates simultaneously hold the battery cell casing. This solves the problem that existing battery cell casing production and slitting devices typically use a two-point clamping method, which easily leads to unstable clamping. Unstable clamping causes the battery cell casing to shake or shift during the cutting process, thus affecting the cutting accuracy and dimensional consistency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The clamping assembly 3 includes a motor 301 and a base plate 307. The motor 301 is installed in the inner cavity of the housing 1. When it is necessary to clamp the battery cell housing placed on the base plate 307, the motor 301 is turned on. With a disc 302 provided on the output shaft of the motor 301, the motor 301 drives the disc 302 to rotate. A cylinder 303 is installed on the disc 302. With four sets of cylinders 303 provided, the disc 302 drives the cylinders 303 to rotate. An L-shaped plate 304 is rotatably fitted on the cylinder 303. A guide post is installed on the L-shaped plate 304. 305. A slider 306 is rotatably fitted on the guide post 305. Four sets of sliding grooves 308 are provided on the base plate 307. When the slider 306 is slidably fitted with the sliding grooves 308, the slider 306 slides in the sliding grooves 308. When a clamping plate 309 is installed on the slider 306, the slider 306 drives the clamping plate 309 to clamp the battery cell housing. A horizontal plate 310 is installed on the base plate 307. When the end of the horizontal plate 310 away from the base plate 307 is installed on the inner wall of the housing 1, the horizontal plate 310 supports the base plate 307.

[0026] With a V-groove 311 provided on the clamping plate 309, the V-groove 311 can clamp round and square battery cell housings. With a rubber pad 312 provided on the V-groove 311, the rubber pad 312 can protect the battery cell housing and prevent excessive clamping force from damaging the battery cell housing.

[0027] With the clamping plate 309 sliding against the surface of the substrate 307, the clamping plate 309 can be more stable during movement. With the substrate 307 located directly below the linear module 202, the cutting assembly 2 can easily cut the battery cell housing.
