A battery stringer positioning and battery appearance inspection method

Abstract

The invention discloses a battery string welding machine positioning and battery appearance detecting method, which comprises the steps of obtaining a string trigger signal through installed string detecting equipment; obtaining a piece trigger signal through a string welding machine; starting a camera to take a picture after a string head signal and the piece trigger signal are received; callingan image analysis algorithm to perform analysis, comparison and calculation on the whole appearance of the obtained picture; and providing a corresponding signal according to an analysis result so asto enable the string welding machine to operate according to the signal. The battery string welding machine positioning and battery appearance detecting method does not need to increase the additionallabor cost, not only can be matched with the new string welding machine, but also can be used for upgrading and transforming the existing string welding machine. The battery string welding machine positioning and battery appearance detecting method positions a battery piece and performs automatic identification and judgment on appearance defects according to the standards set by a user, the detection speed is synchronous with that of the string welding machine, automatic identification, auxiliary diagnosis and grayscale calibration can be performed, the distance between the battery pieces isdetected, pictures of the detected battery pieces can be clearly displayed, data statistics and processing analysis are performed, the welding quality of the battery string is ensured, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of battery stringer welding machines, in particular to a battery stringer positioning and battery appearance detection method. Background technique [0002] 1) Since the existing positioning module of the stringer welding machine basically does not have the appearance detection function of the battery sheet, the battery strings welded by the automatic welding machine often flow into the next process due to various defects, resulting in the failure of the entire assembly and cost waste caused by rework . [0003] 2) In order to prevent the defects, relevant personnel are specially set up at the customer site to inspect this station, but human energy and concentration are limited after all, especially during visual fatigue and night shifts, it is easy to cause bad outflows, and it is impossible to fundamentally Put an end to bad things. Contents of the invention [0004] In view of the above-mentioned shortcomings e...
