Embodiment Construction

[0024] see Figure 1 to Figure 11 , The visual device of solar cell printing back silver equipment has three mechanisms: pre-press visual imaging and its collection and processing mechanism, post-press visual imaging and its collection and processing mechanism, screen alignment imaging and its collection and processing mechanism. The imaging and its collection and processing mechanism are pre-press visual imaging and its collection and processing mechanism. The first camera 14 of 13 is placed directly above the preprinted cell 12 of the detected object; the first camera 14 is connected with the first video capture card 15; Chip defect detection module and man-machine interface are composed of three parts. The imaging and its collection and processing mechanism are post-press visual imaging and its collection and processing mechanism. The second camera 24 is placed directly above the printed cell 22 of the object to be detected; the second camera 24 is connected to the first ...

Abstract

The invention provides a vision device of solar cell back silver printing equipment, which is used for positioning and detection in a solar cell back sliver printing process and relates to the technical field of solar cell back silver printing equipment. In the device, a light source capable of providing light for a camera provided with a lens is arranged, a detected object is placed in right front of the lens, and the camera is connected with an acquisition card arranged in a computer; a camera positioning straightedge is arranged between a backlight source and the camera; and the computer reads the image information of the camera, and processing software performs defect detection and positioning or screen frame calibration. The device of the invention can detect if the cell is cracked before and after printing automatically, improve yield and rate of finished products, determine the positions of the cell before printing and a silk screen, keep the relative positions of the cell and the silk screen consistent all the time, improve the reprinting precision and the like, effectively improve the printing quality, the rate of finished products and the production efficient of a solar cell production line.

Description

technical field [0001] The invention relates to the technical field of solar battery sheet printing equipment, in particular to a visual device for positioning and detecting solar battery sheets in the process of back silver printing. Background technique [0002] At present, under the trend of vigorously promoting green and environmentally friendly energy around the world, solar energy technology has become the mainstream of green energy technology. With the increasing popularity of solar technology, users have higher and higher requirements for the printing process of solar cells (referred to as cells). When batteries are mass-produced on the production line, due to their fragile characteristics, the production capacity and yield of the production line are restricted. At the same time, the positional deviation of the cells during transmission on the production line will restrict the improvement of the repeated printing accuracy of the production line. Contents of the in...
