Abstract

The invention discloses a soft-packaged lithium battery thickness measuring device, relates to the field of manufacturing of batteries, and specifically relates to lithium ion production equipment or methods. The device is characterized by comprising a lower base (1) and an upper base (2), wherein a wire guiding frame (3) is arranged on the upper base (2), a puncture needle (4) is arranged below the wire guiding frame (3), a thickness tester (5) is arranged on one side of the wire guiding frame (3), a control system (6) is arranged on the side of the upper base (2), a level (7) is arranged at the top of the upper base (2), and the upper base (2) is spaced from the lower base (1) by an adjustable strut and is parallel to the lower base (1). The device not only overcomes the defects of low accuracy, low consistency, narrow application range and low contrastable significance in present test of soft-packaged lithium ion batteries, but also has the advantages of high accuracy, strong consistency, wide application range and strong contrastable significance; and the thickness of the tested soft-packaged battery is maximum thickness, so the device has great modular design reference significance relative to a micrometer for testing random thickness.

Description

technical field [0001] The invention relates to the field of battery preparation, in particular to lithium ion production equipment or methods. Background technique [0002] Soft-pack batteries are favored by the market due to their high energy density and good cycle life. In terms of energy density, soft-pack batteries are packaged with aluminum-plastic films, which are smaller than metal shells and plastic shells in terms of volume and quality. have great advantages. At present, the method of testing the thickness of the pouch battery mainly uses a micrometer to test one or several points of the pouch battery, which is unrepresentative and has large errors. At the same time, because the thickness of the pouch battery is the maximum thickness when forming a module, the micrometer test is used. The battery thickness cannot measure the maximum thickness of the ruler battery. The patent (CN200944041Y) discloses a lithium battery thickness detection device, which has high req...
