Embodiment Construction
[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0026] Such as Figure 1-3 As shown, the present invention provides a cell printing device, including a printing plate 2, a sealing box 4 and an air intake pipe 5, and the specific structure is as follows:
[0027] see figure 2 and 3 , the printing plate 2 is made of non-corrodible metal material or tempered glass, with a thickness of 1-10mm, and the middle part of the printing plate 2 is evenly arranged in parallel with several printing grooves 21 penetrating the printing plate 2, each printing The distance between the grooves 21 is determined according to the printing process, and the printing groove 21 is composed of an upper groove body 211 and a lower groove body 212 which communicate with each other. The longitudinal section of the upper tank body 211 is funnel-shaped with a wide upper ope...

Abstract
The invention relates to the technical field of battery piece printing and particularly relates to a battery piece printing device and a printing method thereof. The battery piece printing device comprises a printing plate, a sealing box and an air inlet pipe; a plurality of printing slots passing through the printing plate are uniformly distributed in the printing plate; each printing slot is composed of an upper slot body and a lower slot body communicating with each other; an opening is formed in the bottom of the sealing box, and an air inlet pipe hole is formed in the top of the sealing box; the air inlet pipe communicates with an inner cavity of the sealing box through the air inlet pipe hole; and when being used, the battery piece printing device is sequentially provided with a battery piece, the printing plate, the sealing box and the air inlet pipe from bottom to top. Slurry is extruded by virtue of air pressure to ensure that the slurry is in contact with the battery piece because being extruded from the upper slot bodies to the lower slot bodies of the printing plate, and scraping and brushing the printing plate by using a scraper in a pressurized way is replaced, so that the loss of the printing plate is effectively reduced, and the service life of the printing plate is prolonged; in addition, the shapes and sizes of the upper slot bodies and the lower slot bodies of the printing plate can be regulated, so that an ideal grid line is formed, and grid breaking does not easily happen.
Description
technical field [0001] The invention relates to the technical field of battery sheet printing, in particular to a battery sheet printing device and a printing method thereof. Background technique [0002] In the process of converting light energy into electrical energy in a solar cell, the internally generated carriers need to be collected and extracted through the externally printed grid electrodes, and then connected to the external circuit to deliver the current. In the prior art, the screen printing method is often used to form the grid line electrodes. The screen printing method is to use the basic principle that the mesh of the screen graphic part is transparent to the paste, and the non-graphic part of the mesh is impermeable to the paste. Pour the slurry at one end of the screen, apply a certain pressure on the slurry part of the screen with a scraper, and move towards the other end of the screen at the same time, the slurry is squeezed from the mesh of the graphic p...
