Battery short circuit detection device

Abstract

The invention discloses a battery short circuit detection device comprising a rack, a slide base, a fixed frame, a test cylinder, a vertical slide rail and a test pressing block. The slide base is installed on the rack. The fixed frame is installed on the slide base through the vertical slide rail. The test cylinder is installed on the top part of the slide base and the piston of the test cylinder is vertically downward and connected with the top part of the fixed frame. The test pressing block is installed on the fixed frame. The battery short circuit detection device is installed in an area for detection when detection is performed, the test pressing block is arranged above a member for detected, and the test cylinder pushes the fixed frame to downwardly slide along the vertical slide rail so as to drive the test pressing block to be downwardly contacted with the member for detection to complete detection; and after completion of detection, the test cylinder contracts to drive the fixed frame to upwardly slide along the vertical slide rail, and the test pressing block is separated from the member for detection to recover to the initial state. The beneficial effects are that the battery short circuit detection device can be quickly installed on the position requiring detection in the lithium battery production link so that the process can be simplified and the production efficiency can be enhanced, and adaptability is high and the test accuracy is high.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting a short circuit of a battery cell in the production process of a lithium battery, and belongs to the technical field of testing. Background technique [0002] ​Lithium batteries refer to batteries containing lithium in the electrochemical system, including metal lithium, lithium alloys, lithium ions, and lithium polymers. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Li-ion batteries do not contain metallic lithium and are rechargeable. [0003] In order to ensure the quality of lithium batteries and the safety of production, short-circuit detection is required in many key processes in the production process of lithium batteries; at present, if detection is required, professional testing equipment...

Problems solved by technology

[0003] In order to ensure the quality of lithium batteries and the safety of production, short-circuit detection is required in many key processes in the production process of lithium batteries; at present, if detection is required, professional detection equipment must be used, and a detection process is added to make the production process more complicated.

At present, in the lithium battery production industry, there is a lack of a device that can be embedded in other processes for fast short-circuit detection
