Problems solved by technology
[0005] The above-mentioned patents are aimed at the obvious defects such as dirt and large burrs of the button battery or the remaining power of the button battery, and do not detect the concave point of the negative electrode of the button battery; the detection of the concave point of the negative electrode of the button battery is an important item in the shape inspection. The existence of battery pits not only affects the appearance, but also because the pits are often produced by mechanical impact, it will have a certain impact on the safety and quality stability of the button battery in the later use.

The invention provides a button battery cathode concave point detection device and method. The device comprises a camera, a lens, an area source and a non-glare grating, wherein the camera forms a certain angle with the horizontal plane; the area source and the non-glare grating form an imaging system; the grating is placed in a manner of clinging to the area source; and both the grating and the area source are parallel to a detected button battery without shielding the lens. The device and method are capable of avoiding the interferences generated to hard spot detection due to embossment of button battery cathodes, thereby greatly improving contrast between concave point defects of button batteries and normal areas during imaging, and avoiding interferences caused to the detection by cathode websites.
Description
technical field [0001] The invention relates to the technical field of product detection, in particular to a device and method for detecting pits in the negative electrode of a button battery. Background technique [0002] Button batteries are one of the important power supply components in electronic equipment. The quality and performance of button batteries will directly affect the operating status of electronic equipment, and the quality inspection indicators mainly include battery power and appearance defects. [0003] In terms of battery power detection, the patent No. CN201233437 discloses a button battery detector, which uses a detection circuit to convert the battery power into the brightness of the indicator light bulb, and the battery power is represented by the brightness; the patent No. CN108535655 discloses a button battery detection device , including the feeding part, the detection part, the battery release part, etc. to complete the fully automatic detection ...
