The width that inkjet printing is prepared solar cell surface grid line is tens of microns, in spray printing process, in ink gun and silicon chip relative motion process, complete the spray printing of multilayer grid line, this transmission precision to silicon chip course of conveying has proposed strict requirement, for realizing high-quality ultra-fine grid inkjet printing, must improve stability and the precision of silicon chip transport process.
Compared with prior art, the invention has the beneficial effects as follows:
(1) independent heating transmits seat design, possesses silicon chip on-line heating function, and heating is concentrated, and heat diffusion impact is to external world little.
Connecting gear of the present invention transmits in seat and all has heating element at the silicon chip of fixing silicon chip, by Miniature temperature control module, can realize the independence of silicon chip, on-line heating function, between resistive heater and silicon chip, be also provided with porous even heat plate, the thermal field uniformity is high, add Heat stability is good, guarantee that silicon chip need complete inkjet printing in transport process, during the surface metal metallization processes such as laser transfer, all the time in temperature constant state.
In addition, the present invention adopts independent transmission seat heating design, and silicon chip heating is concentrated, heat diffusion is little, avoided in the silicon chip surface metallization processes such as inkjet printing, because heat diffusion causes inkjet print head nozzles aperture ink inside dry solidification, caused the situation of plug-hole fault to occur.
(2) the full supporting construction of conveyer belt, transmits stability high;
Public affairs of the present invention have under the conveyer belt of silicon chip high accuracy connecting gear of on-line heating function and are designed with supporting plate structure, can effectively prevent from transmitting the shake of seat in transmitting procedure, improve the stability that silicon chip transmits.
(3) adopt side guide frame, transport process linearity is high;
The both sides of transmitting seat are provided with accurate side guide, in moving process, transmit seat and move in the precise guide rail of both sides, and precision of rectilinear motion is high, has improved precision of rectilinear motion when silicon chip need complete ink-jet printed surface metallization process in transport process.
