Automobile battery box air tightness automatic detection device

Abstract

The invention discloses an automated detection device for air tightness of an automobile battery box. A line body is adopted to convey the automobile battery box, an air tightness detection station is arranged beside the line body, the automobile battery box is stopped on the air tightness detection station through signal switch control, the air tightness detection station is provided with an automobile battery box positioning mechanism, a cover box joint part sealing mechanism, a plug-in module insertion hole sealing mechanism and an air pressure detection mechanism, the mechanisms replace manpower with controller coordination control to complete external sealing and air inflation of the automobile battery box and air pressure detection, efficiency is improved greatly while high detection precision can be provided so that detection quality can be guaranteed, and production cost is lowered.

Description

technical field [0001] The invention relates to an automatic detection device for the airtightness of an automobile battery box. Background technique [0002] The car battery box is an important part for packaging car batteries and related electronic accessories. The industry has high airtightness requirements for it. On the one hand, it is to prevent dust pollution, and on the other hand, it is to prevent the intrusion of water vapor from interfering with corrosion of electronic accessories ( It will cause a short circuit of the battery) and affect the safety of the car; in addition, maintaining a certain pressure environment in the box is also a necessary condition to ensure the stable operation of the lithium battery. Therefore, the finished car battery box must be tested for air tightness. [0003] At present, the assembly of battery boxes in the domestic automobile production industry is usually handed over to metal processing enterprises for OEM production. These ente...

Problems solved by technology

[0004]Although the above-mentioned manual air tightness testing work can be done very meticulously, the disadvantage is that the efficiency is low and the work progress is slow, especially for the cover, the box body and the connector The plugging of the module placement hole, the installation and disassembly of the air pump pipeline and the air pressure gauge are all cumbersome and time-consuming operations

According to actual statistics, it usually takes 1 to 1.2 hours for the detection of a box. Faced with hundreds of boxes to be tested, even if multiple groups of workers operate at the same time, the daily detection amount is limited.

In addition, due to the high labor intensity of the workers, it is easy to misuse for a long time. For example, the plugging and pipeline connection procedures are not in place, which increases the detection error and makes many qualified boxes as "waste products".

And these "waste" battery boxes still need to be manually picked out for re-inspection, which undoubtedly greatly increases labor costs
