Squeegee Adaptive Mechanism for Solar Cell Screen Printing Machine and Solar Cell Screen Printing Machine

Abstract

The invention discloses a self-adaptation scraper mechanism suitable for a solar cell screen printer and the solar cell screen printer to improve the balance of the printing force of a scraper during the printing process. The self-adaptation scraper mechanism comprises a left air cylinder, a right air cylinder and a middle supporting beam, wherein the left air cylinder and the right air cylinder are arranged on a left guide rail sliding block and a right guide rail sliding block respectively, and the middle supporting beam is used for installing a scraping blade assembly. The left end and the right end of the middle supporting beam are respectively and fixedly provided with an elastic connecting piece, each elastic connecting piece is fixedly connected with one transition piece, and each transition piece is fixedly connected with one air cylinder connecting plate. The air cylinder connecting plate on the left is fixed to a piston rod on the left air cylinder, and the air cylinder connecting plate on the right is fixed to a piston rod on the right air cylinder. The scraping blade assembly is hinged to the position below the middle supporting beam through a hinged shaft structure. According to the self-adaptation scraper mechanism, the self-adaptation adjustment of the scraping blade assembly is achieved, and the balance of the printing force is effectively improved.

Description

technical field [0001] The invention relates to a scraper adaptive mechanism suitable for a solar cell screen printing machine and the solar cell screen printing machine, which are used to improve the balance of the printing force of the scraper in the screen printing process, and belong to the field of special equipment for solar cell production. Background technique [0002] Photovoltaic power generation is an effective way to solve the world's energy crisis and environmental problems. However, at present, the cost of photovoltaic power generation is high, and it is difficult to popularize and apply it on a large scale. To a large extent, it still relies on national policy subsidies and lacks its own hematopoietic function. At present, the key issue in the development of the photovoltaic industry is to reduce the cost of power generation, and the direct way to reduce the cost of photovoltaic power generation is to improve the photoelectric conversion efficiency of cells, an...

Problems solved by technology

[0011] In order to improve the balance of the printing force of the squeegee in the printing process, the traditional screen printing machine squeegee is installed as a rigid connection, the guide rails of the printing device are not parallel, the squeegee and the screen are not parallel, and other factors can easily cause unbalanced printing pressure, resulting in printing. Due to problems such as quality decline, high fragmentation rate, and high equipment failure rate, the present invention aims to provide a scraper adaptive mechanism suitable for solar cell screen printing machines. Self-adaptive swing adjustment of a certain range of components; the self-adaptive rotation of the squeegee assembly within a certain angle range is realized through the rotary hinge mechanism, so that the contact between the squeegee and the screen plate is even, and the balance of the printing force of the squeegee in the screen printing process is improved. , which reduces the complexity of the coordination accuracy between guide rails, scrapers, screens, and printing plates, and effectively solves the problem of non-parallel scrapers and screens, thereby improving printing quality, equipment reliability, and reducing fragmentation rates
