Abstract

The invention discloses a device for detecting the pressure of a sealed cover of a cell. The device comprises a transporting passage of the sealed cover; an outlet of the transporting passage is provided with a feeding slide block connected with a feeding cylinder; the lower part of the feeding slide block is provided with a detection mold cavity; one side of the detection mold cavity is provided with a feed pressing block and a feed pressing cylinder; the other side of the detection mold cavity is provided with an air inlet module; the lower part of the detection mold cavity is respectively provided with three passages, namely a low-pressure sealed cover passage, a normal sealed cover passage and a high-pressure sealed cover passage; and an outlet of an air outlet passage is provided with a pressure sensor which is respectively connected with a drive device of a low-pressure guide plate and a drive device of a high-pressure guide plate by an electric appliance control device. The device has the following advantages: the device has rapid and accurate detection, can ensure the production quality and safe use of the cell, reduce labor intensity of laborers, improve production efficiency and reduce production cost.

Description

technical field [0001] The invention belongs to the technical field of pressure detection devices, and relates to a device for detecting the pressure of a battery cover. Background technique [0002] The battery cover is an important part set on the top of the battery. It is the last cover on the battery when the battery is produced. The gas after the reaction has a pressure relief effect, so it is also a battery explosion-proof safety device. However, after the existing battery cover is produced, its detection is all carried out manually. The specific method is to put the cap to be tested into the testing mould, then inject high-pressure gas into the testing mould, and judge whether the cap is qualified according to the range of the upper limit and lower limit of the pressure that the cap can withstand. If the withstand pressure of the cover is below the set lower limit, it is identified as a low-pressure cover; if the cover’s withstand pressure is above the set upper lim...
