Abstract

A method and device for detecting the welding strength of a battery. The device includes a suction mobile device and a suction nozzle. The suction nozzle is arranged on the mobile end of the suction mobile device. One end of the battery pack is welded with a conductive sheet, and the electrodes on the conductive sheet are connected to the battery. One end of the battery in the group is welded, the suction nozzle sucks the other end of the battery, and the suction mobile device pulls the battery away from the conductive sheet under the action of a constant tension. If one end of the battery does not separate from the electrode, it proves that the welding strength of the battery meets the requirements. Welding standard, otherwise it proves that the battery welding strength does not meet the welding standard. Because the present invention adopts the suction moving device and the suction nozzle, the suction nozzle is arranged on the moving end of the suction moving device, compared with the prior art, the pulling force is constant, and the number of suction nozzles can be the same as the number of batteries, so that the detection device once It can detect the welding strength of several batteries and electrodes, which has the advantages of convenient detection, high detection efficiency and no damage to the electrodes.

Description

technical field [0001] The invention relates to the technical field of battery welding detection, in particular to a method and device for detecting battery welding strength. Background technique [0002] Lithium batteries have the advantages of high capacity, small size, and light weight. Lithium battery packs composed of multiple lithium battery cells are used in many fields due to their higher capacity. For example, in electric vehicles, lithium battery packs can be used Replace traditional lead-acid batteries. With the rapid development and increasingly wide application of lithium-ion battery products, the requirements for their safety and product quality are also increasing. Therefore, it is very important to ensure the reliability of the internal solder joints of lithium-ion batteries. [0003] At present, since the lithium battery pack contains multiple batteries, the multiple batteries are distributed in an array, and the conductive sheet is provided with multiple e...
