Steel ball sealing device for lithium batteries

Abstract

The invention provides a steel ball sealing device for lithium batteries. The steel ball sealing device comprises a controller, a push unit, a fixation unit and a steel ball conveying unit. The fixation unit contains a fixed plate, a first air cylinder, a second air cylinder and a fixed spring. Two sides of the upper part of the fixed plate are fixedly connected with the first air cylinder and the second air cylinder respectively. A second piston rod of the second air cylinder penetrates through a spring baffle positioned on the fixed plate. The spring baffle is abutted against the second air cylinder. The top of the second piston rod is fixed with a battery baffle which is placed on the fixed plate. One end of the fixed spring is fixed to one face of the battery baffle, and the other end of the fixed spring is fixed to one face of the spring baffle. Motion direction of the fixed spring is parallel to the fixed plate. During operation, positioning of a lithium battery is appropriate. Inclination of the lithium battery housing or damage to the housing due to too tight fixation is avoided. In addition, on the precondition of high efficiency and high quality, the steel ball sealing device can be suitable for sealing requirement of different models of lithium batteries according to needs.

Description

technical field [0001] The invention relates to the manufacture of lithium batteries, in particular to a lithium battery steel ball sealing device. Background technique [0002] Lithium batteries are being used more and more widely and people's demand is also increasing day by day. However, the disadvantages in the production process of lithium batteries are gradually revealed. In the process of lithium battery production, when using steel balls to seal lithium batteries, manual operations are often used, resulting in many unqualified products. Therefore, mechanical and automated steel column sealing machines have emerged as the times require, but there are still many The problem needs to be solved urgently. [0003] In the patent CN202695561U lithium battery negative pressure sealing machine, there are two problems: one is that the positioning compression is too tight during positioning, resulting in deformation of the lithium battery shell or deflection of the lithium bat...

Problems solved by technology

In the process of lithium battery production, when using steel balls to seal lithium batteries, manual operations are often used, resulting in many unqualified products. Therefore, mechanical and automated steel column sealing machines have emerged as the times require, but there are still many problem to be solved

[0003] In the patent CN202695561U lithium battery negative pressure sealing machine, there are two problems: one is that the positioning compression is too tight during positioning, resulting in deformation of the lithium battery shell or deflection of the lithium battery shell during the process; the other is , not suitable for the sealing production needs of various types of lithium batteries, and the size of the sealing steel ball cannot be adjusted
