Welding locating device for safety protection components of lithium ion battery

Abstract

The invention discloses a welding locating device for safety protection components of a lithium ion battery. The welding locating device comprises a tray (2), wherein a plurality of component accommodating cavities (4) are formed in the top of the tray (2) and used for accommodating the safety protection components (1) required to be welded; and a cover plate (3) is connected to the top of the tray (2), and a plurality of welding windows (7) are formed at the positions, corresponding to the plurality of component accommodating cavities (4), in the cover plate (3). The welding locating device disclosed by the invention, during assembly of the safety protection components, can not only draw the production efficiency of the safety protection components into consideration but also ensure that the quality of the safety protection components can meet the safety protection use requirements of the battery, further guarantees safety use of the lithium ion battery, effectively improves the market competitiveness of lithium battery products, and is conductive to extensive application to production.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a welding positioning device for a lithium-ion battery safety protection component. Background technique [0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools. [0003] For lithium-ion batteries, battery safety is the most concerned issue at present. For this reason, battery manufacturers usually install safety protection components on the batteries, which can improve the safe use of batteries, and safety protection components need to be pre-installed. It can only be used on the battery cell after being assembled according to the standard. Therefore,...

Problems solved by technology

Therefore, the quality of the assembly of safety protection components will directly affect the use effect on the battery, that is, if the assembly of safety protection components is not in place or unqualified, its safety protection performance in battery use will be reduced

However, there is currently no device that can take into account the production efficiency of the safety protection components when assembling the safety protection components, and at the same time ensure that the quality of the safety protection components can meet the safety protection requirements of the battery
