Embodiment Construction

[0052] see Figure 1 to Figure 4 , the present invention provides a battery tab detection method based on machine vision, which includes the following steps:

[0053] (1) Three sets of camera devices 1 are respectively arranged to collect the perspective images of the front, back and side of the battery tab 6 respectively;

[0054] (2) Three sets of light source control devices and three sets of light sources connected to the devices are respectively provided, and the light source control devices are used to adjust the irradiation brightness of the light source so that the light source produces a uniform light-emitting surface;

[0055] (3) A baseband device for stabilizing the battery tab 6 is provided so that the battery tab 6 to be tested remains stable when it is in the detected position;

[0056] (4) A deformation auxiliary device is provided to cause predetermined deformation of the battery tab 6 to be tested;

[0057] (5) A display device is provided to display the cu...

Abstract

The invention discloses a machine vision-based battery tab detection method. The machine vision-based battery tab detection method comprises the following steps: (1) arranging three sets of image pick-up devices; (2) arranging three sets of light source control devices and light sources; (3) arranging a baseband device; (4) arranging a deformation auxiliary device; (5) arranging a display device; (6) arranging an alarm device; (7) arranging an intelligent detection device; (8) putting a battery tab in place, turning on the power sources, keeping the devices in a working state, transmitting a control command by the intelligent detection device to the light source control devices to adjust the light sources, then transmitting the control command to the image pick-up devices, collecting perspective images of a side face, a front face and a reverse face of the battery tab, analyzing and processing each frame of received perspective image of the battery tab by the intelligent detection device to intelligently detect whether the battery tab is qualified. The invention also discloses a detection system using the detection method.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to a machine vision-based battery tab detection method and a detection system for implementing the method. Background technique [0002] At present, in the battery tab processing industry, there are quality defects such as single-layer battery tabs, out-of-tolerance dimensions, bubbles, and poor welding. The traditional manual detection method has the disadvantages of slow speed, low efficiency, false detection, and high rate of missed detection, which cannot meet the production needs. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method for detecting battery tabs based on machine vision to solve the above problems, and a detection system for implementing the method. [0004] The technical scheme that the present invention adopts for realizing the above object is: [0005] A method for...
