Zinc paste visual detection method and device

Abstract

The invention discloses a zinc paste visual detection method and device. The device includes a PLC controller, a visual controller and a camera; the PLC controller is connected with the visual controller; the visual controller is connected with the camera; the camera is arranged at the right upper side of a to-be-detected cylindrical battery steel shell; the front end of the camera is provided with a light source, and the light source is an annular light source. The method and the device have the beneficial effects that an image processing method is utilized to realize detection of a battery zinc paste, the battery zinc paste can be detected full-automatically, and the method and the device are good in detection effect, high in detection precision, safe and reliable, simple in structure and convenient to operate, improve the work efficiency and reduce the labor intensity.

Description

technical field [0001] The invention relates to the technical field related to battery preparation, in particular to a zinc paste visual detection method and a device thereof. Background technique [0002] The most popular alkaline manganese batteries are cylindrical and button-shaped, and there are also square and flat varieties. The shell of the cylindrical structure battery is a nickel-plated steel shell with a positive cap, which doubles as the positive current collector. In close contact with it in the shell is a positive electrode ring (cathode) made of electrolytic manganese dioxide, graphite and carbon black. The middle is filled with zinc paste prepared by zinc powder and gel lye, that is, the negative gel (anode), and a brass current collector is inserted in it. [0003] The viscosity of zinc paste cannot be ignored in actual production, and it plays a vital role in the stability of zinc paste injection weight and injection state. If the viscosity is too small, ...

AI Technical Summary

Problems solved by technology

There are two main types of poor injection status: one is that the tailing or dripping forms the zinc paste to contact the release paper or the positive electrode ring, resulting in an internal short circuit; Incomplete and affect performance

[0005] In the prior art, there is no direct and effective zinc paste visual detection method to intuitively detect the injection state of zinc paste in the battery steel case, such as: missing injection, under-injection, tailing, overflow, and bad diaphragm paper. Therefore, the yield rate of the battery is greatly reduced, and at the same time, there are certain safety hazards when users use unqualified battery products.
