Measuring mold for pole pieces

Abstract

The invention discloses a measuring mold for a pole piece, which comprises a main formwork, a baffle plate is fixed on one of the adjacent two sides of the main formwork, and a radial adjustment plate and a radial adjustment plate are respectively arranged on the other adjacent two sides of the main formwork. The horizontal adjustment plate, the two baffles, the radial adjustment plate and the horizontal adjustment plate are surrounded by a groove, and the radial adjustment plate and the horizontal adjustment plate are respectively provided with a radial adjustment device and a horizontal adjustment device. The radial adjustment device includes a diameter The radial adjustment screw is fixed on the radial orientation sleeve; the lateral adjustment device includes a lateral adjustment screw, and the lateral adjustment screw is fixed on the lateral orientation sleeve. Beneficial effects of the present invention: the mold can be moved at will, which is convenient for measuring the size of the pole piece; the online measurement of the pole piece size can measure one or more pieces, which increases the accuracy of measurement; the test method will not damage the pole piece, and the quality of the inspection piece is improved And reduce the waste of materials; the main mold is easy to operate, has strong practicability, and is convenient to store.

Description

technical field [0001] The invention relates to the technical field of battery pole piece inspection, in particular to a mold for measuring the size of a die-cut pole piece. Background technique [0002] With its high energy density, high cell voltage, high power density, no memory effect, fast charge and discharge, excellent cycle performance, long life, excellent safety performance, and environmental protection, lithium batteries have become indispensable for coal, oil, and natural gas. Alternatives to renewable resources. How to produce high-capacity, high-density and high-safety lithium-ion batteries has always been the focus of research by scientists at home and abroad. At present, the production of lithium batteries generally uses a die-cutting machine to cut the pole piece into a suitable size. Although the efficiency and quality of the die-cutting machine have been greatly improved over the years, there are still errors in the size of the die-cutting. For example, a...

Problems solved by technology

The existing treatment method is to measure the size of the material area and the total size of the pole piece with a steel ruler or a vernier caliper after die-cutting. This process is not easy to operate in production, and the error is large. Reduced efficiency affects production progress
