Abstract

The invention aims at providing an image recognition device. According to the image recognition device, welding spots for welding silver wire on the surface of a silver foil in an acquired image are recognized. The acquired image comprises at least one first region corresponding to the silver foil and at least one second region corresponding to the silver wire. The image recognition device comprises a gray value?acquisition unit, a feature extraction unit and a welding spot determination unit, wherein the gray value?acquisition unit is used for acquiring the gray?value of each pixel in the first region and the second region; the feature extraction unit is used for acquiring the feature points of the first region according to the gray?value of each pixel in the first region; and the welding spot determination unit is used for seeking the welding spots in the second region according to the gray?value of each pixel in the second region. In comparison with the prior art, recognition is carried out according to the gray difference between the silver foil and the silver wire, the position of the silver wire is sought around mass points of the silver foil, the welding spots are finally determined, and the positions of the welding spots are then conveniently, quickly and automatically recognized.

Description

[0001] technical field [0002] The invention relates to the field of image recognition, in particular to a visual image recognition device for realizing automatic welding of solar cell arrays. Background technique [0003] The parts of the solar cell array used in domestic space are basically welded by manual welding. The manual positioning method is used to weld the silver wire on the silver foil on the back of the solar wing sail by resistance spot welding. mechanism, each solder joint needs to repeat the process of coarse adjustment, aiming, fine adjustment, trial pressing and then fine adjustment in order to accurately move to the top of the solder joint. [0004] This method is time-consuming and inefficient. It takes about 2 minutes to complete the soldering of a solder spot on a piece of silver foil, which greatly affects the production schedule. At the same time, due to the large number of wires and components on the surface of the solar cell array, manual weldi...
