Abstract

The invention discloses a visual detection method for the appearance of a semi-finished battery. The visual detection method comprises the steps that a qualified battery product picture is photographed and registered as a standard picture; the search range is searched for a picture of a product to be detected through a visual controller, wherein the picture is the most similar to the registered standard picture; the similarity of the picture to be detected and the standard picture is calculated; on the basis of picture analysis, the similarity of the product to be detected and the standard picture is judged, and if the similarity is larger than a set value, position offset correction is performed on the obtained picture of the product to be detected; a battery negative electrode cap is detected through a picture processing method, whether flaws exist in the region outside the negative electrode cap or not is detected through a label setting method. The method is good in detection effect and high in precision; the production efficiency is improved, the uncertainty problem of a current manual visual inspection quality control is eradicated, and it is ensured that the stability of batteries produced in different batches is consistent.

Description

technical field [0001] The invention relates to the technical field related to battery preparation, in particular to a visual inspection method for the appearance of a semi-finished battery. Background technique [0002] Batteries are widely used in people's daily life as a necessity in life, such as remote controls, toys, telephones, calculators, etc. The quality of battery performance directly affects people's quality of life and people's impression of the battery brand. [0003] At present, in the production process of the battery, it is necessary to visually inspect the appearance of the semi-finished battery, such as inspecting the negative cover of the semi-finished battery to see if it has a negative cover, and if so, whether there are black spots on the negative cover and whether there is obvious gravure. ; At the same time, it is also necessary to check whether the sealing ring is exposed, whether there is an outer triangle, and whether the curling is cracked. In ...
