Measuring device for measuring thickness change of soft-pack power battery

Abstract

The invention discloses a measuring device for measuring the thickness change of a soft-pack power battery. The device comprises a supporting chassis, the supporting chassis is obliquely placed, a tray is fixedly arranged at the upper end of a supporting bottom plate, a rotating disc coaxially rotating with the tray is arranged in the tray, a shifting bar is fixedly arranged at the top end of therotating disc, a notch is formed in the supporting chassis, a detecting assembly is arranged right above the tray, and a sliding groove is arranged on the outer side of the supporting chassis, a diverting baffle is fixedly arranged in the middle of the sliding groove, a swinging shaft is arranged on one side of the diverting baffle, a swinging plate is arranged on the swinging shaft, a motor is fixedly arranged at the lower end of the sliding groove, and a conveying assembly is arranged right above the tray. According to the device, by means of the conveying assembly, the rotating disc and thedetecting assembly, the continuous automatic batch detection of the thickness of the battery is achieved, and compared with a traditional device performing single detection on the single battery, thenovel device improves the detecting efficiency of the thickness of the battery; and a PLC controls the motor to work, and the motor controls the swing plate to rotate to one end of the notch, so thatthe classification collection of qualified batteries or unqualified batteries is realized.

Description

technical field [0001] The invention relates to the field of new energy batteries, in particular to a measuring device for measuring the thickness change of a soft pack power battery. Background technique [0002] In related technologies, an important test in the testing project of soft-pack power batteries is to perform repeated charge-discharge tests in a constant temperature environment to measure changes in battery thickness. [0003] Existing measurements of the thickness of pouch batteries usually use the traditional vernier caliper measurement method, but due to different personnel or the same person using the vernier caliper to squeeze the pouch battery in different times of measurement, the extrusion force is different, which will have a certain impact on the measurement results. errors, and it is not possible to accurately measure the change in battery thickness during the test. [0004] The existing patent application number CN201610352726.0 is a measuring device...

Problems solved by technology

[0003] Existing measurements of the thickness of pouch batteries usually use the traditional vernier caliper measurement method, but due to different personnel or the same person using the vernier caliper to squeeze the pouch battery in different times of measurement, the extrusion force is different, which will have a certain impact on the measurement results. error, and it is not possible to accurately measure the change of battery thickness during the test

[0004] The existing patent application number CN201610352726.0 is a measuring device for measuring the thickness change of the soft pack power battery. The displacement sensor can be used to test the battery thickness change, but the battery cannot realize automatic continuity detection, and the battery thickness detection efficiency is low.
