Problems solved by technology

[0003] Since battery separators are mostly made of polymers and are soft in texture, the influence of contact pressure on the deformation of the separator should be minimized when measuring the thickness. At present, most of the produced separators are verified by optical refraction. Determine whether the thickness o

Abstract

The invention discloses a thickness detection device for a battery diaphragm, and relates to the technical field of battery diaphragm production. The problems that in the detection process, pressing concave holes are easily formed in the surface of a diaphragm, and the detection precision is affected are solved. The device specifically comprises a supporting rack, the supporting rack is of a box body structure, a detection plate is fixedly installed at the top end of the supporting rack, a limiting film frame is fixedly installed at the top end of the detection plate, supporting rods are fixedly installed on the two sides of the top of the supporting rack, and a limiting sliding rod is fixedly installed between every two adjacent supporting rods; and a top plate is fixedly mounted between the top ends of the two supporting rods. According to the invention, the verticality displayed by the probe of the electronic dial indicator when the detection rod mechanism encounters an uneven diaphragm or unqualified thickness of the diaphragm is increased, tiny flaws are amplified and displayed, the diaphragm thickness verification precision of the device is enhanced, the device is simple in structure and convenient to operate, and the diaphragm thickness detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of battery diaphragm production, in particular to a thickness detection device of a battery diaphragm. Background technique [0002] The battery separator refers to a layer of separator material between the positive electrode and the negative electrode of the battery. It is a very critical part of the battery and has a direct impact on the safety and cost of the battery. Its main function is to isolate the positive and negative electrodes and make the electrons in the battery unable to The thickness is one of the most basic parameters of the lithium battery separator, which is usually inversely proportional to the permeability of lithium ions and proportional to the mechanical properties of the separator. Therefore, the thickness of the separator should be reduced as much as possible to improve the battery performance under the condition of satisfying the mechanical strength. [0003] Since most of the batt...
