Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cleaning devices, and in particular to an oscillating spray device. Background Art
[0002] In the photovoltaic industry, several N-type or P-type cells currently in mass production all use screen printing equipment to print silver paste on both sides of the cell as grid lines to collect electrons to form current. However, with the advancement of technology, the photoelectric conversion efficiency continues to improve, and the amount of silver paste used is also increasing. In addition, the previous PERC cells and TOPCON cells all used high-temperature silver paste, which can now be domestically produced. However, the low-temperature silver paste used in HJT cells is still dependent on imports. Therefore, using electroplated copper instead of screen-printed silver paste can not only reduce the manufacturing cost of the cell, but also get rid of China's photovoltaic dependence on foreign technology. Therefore, the development of electroplated copper technology is particularly important.
[0003] In the process of patterned electroplating, there is a developing process. The cell is placed on a horizontal transmission chain and sent into a developing tank by the horizontal transmission chain. After a series of process reactions, the exposed dry film / ink is finally developed to obtain the desired pattern. The uncured developer needs to be cleaned off, but in the existing spray cleaning process, due to the fixed position of the nozzle, when the cell passes through, it is inevitable that there will be residual developer in the inner corner of the electroplating slot. As the grid line of the cell gradually becomes thinner, there will be dry film / ink residue at the bottom of the grid line, which will affect the next step of electroplating, resulting in false plating and grid line shedding. Utility Model Content

[0011] A driving assembly is arranged on the mounting frame and is used for controlling the reciprocating movement of the swing plate.
[0012] By adopting the above technical solution, the nozzle moves back and forth perpendicular to the moving direction of the battery cell driven by the swinging disk, and the nozzle sprays and cleans from the upper and lower sides of the battery cell at the same time, so that the nozzle can clean the inner corners on the battery cell, thereby improving the cleaning effect, making the dry film / ink development in the inner corners of the gate line more thorough, and improving the gate line graphic yield.
