Description

Technical Field

[0001] The utility model relates to the technical field of solar cell screen printing, in particular to a rack installation structure and a printing machine. Background Art

[0002] When preparing solar photovoltaic cells, screen printing is mainly used for forming the electrodes of the cells. Printing is performed based on the basic principle that the mesh holes of the graphic part of the screen can pass the slurry, while the mesh holes of the non-graphic part cannot. When printing, the slurry is poured into one end of the screen, and a certain pressure is applied to the slurry part of the screen with a scraper while moving toward the other end of the screen. The slurry is squeezed from the mesh holes of the graphic part onto the substrate by the scraper during movement.

[0003] In order to improve the use of high productivity, printing equipment is constantly being updated. The mainstream now uses turntable printing equipment, that is, a work turntable is set in the center area of ​​the printing machine to transport the battery cells to various work areas. When the turntable printer feeds the film, a camera component is set up to determine the position of the battery cell to be printed, and then the control system controls the screen to adjust it to the accuracy under the action of the adjustment component for printing, and the printing accuracy directly affects the quality of the final battery.

[0004] Existing printing machines have the following defects: (1) The original machine structure is to first install the machine equipment according to the production line requirements, and then install a machine cover on the outside of the machine to prevent dust and ensure safety. The machine cover and the machine are separate structures, which will cause the machine cover to occupy a large space. This leads to limited opening and closing space of the inspection door 2.5 on the top of the machine cover, and only a detachable door can be used; (2) Due to the size and weight of the turntable printing machine, the lighter machine is prone to vibration and jitter when rotating, which will cause the deviation of the printing accuracy of the battery cell to become larger, affecting the quality of the final product; (3) The adjustment accuracy of some precision adjustment equipment of the original adjustment components cannot meet the printing requirements, resulting in a relatively large deviation range.
