A silicon wafer support plate for last coating film of solar cell

The utility model relates to a field especially relates to a silicon wafer support plate for last coating film of solar cell, compares with the last coating film support plate of conventionality, andthe silicon chip four sides can guarantee that only there is the four sides line contact in it with the support plate to wait to process the silicon chip on leaning on the middle part position on thebearing inclined plane, have changed original face contact type, downward tendency toward sliding can be guaranteed to exist by the sloping platform face when the silicon chip material loading, the more stable leans on on the support plate, has guaranteed the stability in the technology transmission course, reduces the shake and the piece condition, the bearing horizontal plane can reach the condition of plating of winding that blocks the coating film existence, as the guard plate device. 本实用新型涉及领域，尤其涉及种用于太阳能电池上镀膜的硅片载板，与常规的上镀膜载板相比，硅片四边靠在承托斜面的中部位置上，可以保证待加工硅片与载板只存在四边线接触，改变了原先的面接触形式；斜台面可以保证在硅片上料时存在向下滑动趋势，更加稳定的靠在载板上，保证了在工艺
