Battery shell surface visual inspection line and its inner bottom surface inspection device

Abstract

The invention relates to the field of battery case detection devices, in particular to a surface visual inspection pipeline and an inner bottom surface detection device for battery cases. The surface visual inspection pipeline for the battery cases comprises the inner bottom surface detection device for the battery cases, wherein the inner bottom surface detection device for the battery cases comprises a workbench and machine vision inner bottom surface detection device arranged on the workbench; the machine vision inner bottom surface detection device comprises an inner bottom surface image capture device, a delivery wheel for delivering the battery cases is arranged on the workbench, battery case accommodating through grooves extending in the axial direction of the delivery wheel are formed in the peripheral surface of the delivery wheel, and the positional relationship between the inner bottom surface image capture device and the delivery wheel meets the condition that each battery case accommodating through groove in the delivery wheel can carry the corresponding battery case to be aligned with the inner bottom surface image capture device at a certain moment for image capture. Images of the inner bottom surfaces of the battery cases can be captured precisely by the image capture device, the accuracy and speed of inner bottom surface detection of the battery cases are increased, and the problem of low detection efficiency of the conventional inner bottom surface detection device for the battery cases is solved.

Description

technical field [0001] The invention relates to the field of battery case detection devices, in particular to a battery case surface visual detection assembly line and an inner bottom surface detection device thereof. Background technique [0002] The commonly used battery case appearance and surface detection methods are mainly manual detection, which has low efficiency, high detection cost and poor detection effect, and is prone to false detection or missed detection. At present, when testing the inner bottom of the battery case, the battery case is usually placed horizontally on the conveyor belt, and photographic equipment such as industrial cameras are set on both sides of the conveyor belt to take pictures. However, because the battery case is cylindrical, during the operation of the conveyor belt It is easy to shake, the position of the battery case cannot be precisely controlled, and the imaging quality of the industrial camera is not high. A Chinese patent applicat...
