Solar cell secondary silk-screen printing and four-lens positioning integrated device

Abstract

The invention discloses an integrated device for secondary screen printing and four-eye positioning of solar cells, belonging to the field of solar cell screen printing, and an integrated device for secondary printing and four-eye positioning of solar cells, including an operating table and a support frame , large servo controller, camera, first small servo controller, first printing head, second printing head, first small servo controller, printing platform, first slide rail, second slide rail, display and host computer; The four-eye camera is controlled by a large servo controller, and the printing platform adjusts the angle to make the positioning of the solar cell precise. The first printing head and the second printing head are controlled by a small servo controller, and the printing of the solar cell is realized through the slide track; The device is combined with machine vision and motion control, the whole process is fully automated, and the alignment speed is fast. At the same time, two printing machines are integrated to complete the secondary printing of solar cells, increase the conversion efficiency of solar cells, achieve efficient production, and effectively reduce production. cost.

Description

technical field [0001] The invention belongs to the field of solar cell screen printing, and in particular relates to a secondary screen printing and four-eye positioning integrated device for solar cells. Background technique [0002] In today's era, science and technology are developing rapidly, production and life are changing with each passing day, but energy issues are becoming more and more tense, and environmental issues are becoming more and more prominent. As a new type of energy, solar energy is increasingly favored by people because of its special advantages of huge reserves, green cleanness, safety and reliability. Photovoltaic The industry has also become a sunrise industry with great development potential. Photovoltaic cells mark the development level of the photovoltaic industry. Reducing production costs and improving photoelectric efficiency are the goals that manufacturers and technical workers have been pursuing. [0003] To increase the conversion efficie...

AI Technical Summary

Problems solved by technology

[0003] To increase the conversion efficiency of solar cells, the main starting point is to maximize the use of light energy and increase the circuit current. Therefore, good electrode contact is crucial to achieving high conversion efficiency of solar cells. Therefore, some mass production uses the method of secondary printing. However, there are errors in manually judging the offset between two printings, the accuracy is not high, it has artificial randomness, and the production efficiency is not high
