Description

Technical Field

[0001] This utility model belongs to the field of cylindrical lithium-ion battery technology, specifically relating to a novel large cylindrical steel shell grooving device. Background Technology

[0002] With the development of power battery technology, cylindrical lithium-ion batteries are increasingly widely used due to their advantages such as good uniformity of individual steel shells, high heat resistance, low risk of explosion, high energy density, low energy density per cell, low internal resistance, wide range of applications, and flexible design. Cylindrical steel shell grooving is an important inspection step in the cylindrical battery cell manufacturing process and a crucial step in ensuring cell safety. However, the existing large cylindrical grooving structure with its V-shaped surface leads to cap sealing defects, causing significant safety hazards and product defects.

[0003] In order to solve the above problems, this utility model is hereby proposed. Utility Model Content

[0004] The purpose of this invention is to propose a grooving device for large cylindrical steel-shell lithium batteries, which solves the problem of changing the original V-shaped groove into a U-shaped structure, ensuring good product sealing after the cap is sealed.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] To solve the above technical problems, the following technical solution is adopted:

[0007] A novel cylindrical steel shell grooving device includes a lifting drive motor, upper and lower movable push rods, a product rotation drive motor, an upper mold positioning fixture, and a hobbing cutter. A transmission cam is connected to the output shaft of the lifting drive motor 1. The upper and lower movable push rods are located above the transmission cam, and an upper and lower rotating movable push rod is connected above the upper and lower movable push rods. The rotation of the lifting drive motor drives the transmission cam to rotate, which in turn drives the upper and lower movable push rods to move upwards. The upward movement of the upper and lower movable push rods causes the upper and lower rotating movable push rods to move up and down. A drive pulley is connected to the output shaft of the product rotation drive motor, and the drive pulley is connected to the upper and lower rotating movable push rods. A fixed base is connected above the upper and lower rotating movable push rods, and the steel shell is located on the fixed base. The upper mold positioning fixture is located above the steel shell, and the hobbing cutter is located on the side of the upper mold positioning fixture and next to the steel shell.

[0008] Furthermore, it also includes an upper support frame and a lower support frame, with the upper support frame located above the lower support frame.

[0009] Preferably, the lifting drive motor is located on the side of the lower support frame.

[0010] Furthermore, the transmission cam is located inside the lower support frame.

[0011] Furthermore, the movable top rod extends through the bottom of the upper support frame.

[0012] Furthermore, the product's rotation drive motor is mounted on the inner wall of the upper support frame.

[0013] Preferably, a hob depth adjustment seat is provided on the top inner side of the upper support frame, an upper mold positioning fixture is connected below the hob depth adjustment seat, a swing arm cutter bar is provided on the side, and a hob is provided below the swing arm cutter bar.

[0014] Preferably, a buffer rubber is provided between the hobbing depth adjustment seat and the upper support frame.

[0015] Preferably, an adjusting nut is provided between the hobbing depth adjusting seat and the upper support frame.

[0016] Furthermore, the hob has a U-shaped structure.

[0017] Beneficial technical effects:

[0018] This utility model solves the problems of poor sealing accuracy and major safety hazards caused by the inability of the V-shaped structure at the groove opening to control the sealing performance of the cap, which leads to product defects. It uses a U-shaped roller cutter to solve these problems. Attached Figure Description

By adjusting the adjusting nut 13, the movement of the hob depth adjustment seat 10 relative to the upper support frame 15 can be controlled.

[0028] The rotating push rod 14, the upper mold positioning fixture 7, and the roller cutter 8 press the steel shell together. The drive pulley 4, driven by the product rotation drive motor 11, rotates the steel shell 6, and the roller cutter 8 cuts across the steel shell 6 to form a groove.
