Cylindrical lithium ion battery internal pressure detection equipment and use method thereof

Abstract

The invention discloses cylindrical lithium ion battery internal pressure detection equipment and a use method thereof. The cylindrical lithium ion battery internal pressure detection equipment comprises a storage mechanism, the storage mechanism comprises a storage frame and a battery body, the battery body is arranged in the storage frame, a negative electrode guide piece is embedded in the bottom face in the storage frame, and sliding grooves are formed in the opposite inner surface walls of the two sides of the storage frame; and a pressing frame is slidably embedded between the two sliding grooves and located below the battery body, fixing bolts are in threaded connection with the positions, close to the two corners, of the top of the storage frame, and a sealing cover is slidably arranged between the outer surfaces of the two fixing bolts in a sleeving mode. According to the invention, a rack can be effectively jacked up through a supporting spring and a pressing rod, then the rack can lift the pressing frame through the pressing piece, the battery body can effectively extrude the pressing frame in the process that the battery body is effectively placed into the storage frame, and then the pressing frame can drive the rack to move through the pressing piece, so that the moving rack can effectively drive the linkage gear to effectively rotate.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, in particular to a cylindrical lithium-ion battery internal pressure testing equipment and a method for using the same. Background technique [0002] Lithium-ion batteries are widely used in notebook computers, camcorders, digital cameras, personal digital assistants (PDAs), mobile communication terminal products and power tools, etc. It is used in harsh environments with extremely low temperature and thin air pressure, such as scientific investigations in the North and South Poles, mountaineering expeditions, and power drives for high-power discharges. In the process of cell design and production, it is necessary to understand materials, manufacturing processes, and cell structures. The factors are the amount of gas generated when the battery is pre-charged, and the structural design of the battery and the cap is carried out based on this information, so that the battery has better env...

Problems solved by technology

[0003] However, in the existing technology, the actual mechanism of the existing cylindrical lithium-ion battery internal pressure detection equipment is fixed, and most of them can only detect a single cylindrical lithium-ion battery, and thus cannot effectively detect the state of the cylindrical lithium-ion battery for continuous use. , resulting in poor actual use of the equipment. The actual detection operation process of the existing cylindrical lithium-ion battery internal pressure detection equipment is relatively cumbersome, resulting in low actual use efficiency of the equipment. At the same time, the actual use process of the existing cylindrical lithium-ion battery internal pressure detection equipment It is impossible to monitor the power condition of the cylindrical lithium-ion battery, which makes the actual use of the device less effective
