Abstract

The invention relates to a battery welding intensity detecting method and device. The device comprises an adsorption moving device and suction nozzles, wherein the suction nozzles are arranged on the moving end of the adsorption moving device; a conducting sheet is welded at one end of a battery pack; an electrode arranged on the conducting sheet is welded with one end of a battery in the battery pack; the other end of the battery is sucked by the suction nozzle; the adsorption moving device pulls the battery towards the direction far away from the conducting sheet under the effect of constant tensile force; if one end of the battery is not separated from the electrode, the condition proves that the battery welding intensity meets the welding standard; otherwise, the condition proves that the battery welding intensity does not meet the welding standard. The adsorption moving device and the suction nozzles are used, and the suction nozzles are arranged on the moving end of the adsorption moving device, so that compared with the prior art, the device has the advantages that the tensile force is constant; the number of the suction nozzles can be the same as the number of the batteries. The detecting device can detect the welding intensity of a plurality of batteries and the electrode in one step, and has the advantages that the detection is convenient; the detection efficiency is high; the electrode cannot be damaged, and the like.

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...
