A semi-automatic inserting machine for pe process

Abstract

The invention discloses a PE process semi-automatic wafer inserting machine which comprises an operating platform and a sliding trolley. The operating platform is an inclined slope. A set of continuous wedge-shaped protrusions are arranged along the center line of the operating platform. A recessed portion erected on the wedge-shaped protrusions is arranged on the bottom face of the sliding trolley. A lever extending from the bottom of the sliding trolley to the upper surface of the sliding trolley is arranged in the recessed portion. The bottom end of the lever abuts against the wedge-shaped protrusions. The upper portion of a supporting point of the lever is connected with the sliding trolley through a spring. A support perpendicular to the operating platform is arranged on the sliding trolley. Wafer inserting of a PE process is conducted through the PE process semi-automatic wafer inserting machine, operation is simple, a silicon wafer is placed along the support, the silicon wafer can be inserted through the wafer inserting machine in a clamping point of a time, meanwhile, the wafer inserting machine moves to the next clamping point and prepares for inserting one silicon wafer. According to the PE process semi-automatic wafer inserting machine, wafer inserting efficiency is improved, meanwhile, the problems that a coating film of the silicon wafer can be scratched easily and fragments are generated in manual operation are solved, a wafer inserting rate is improved, and product quality of the silicon wafer is guaranteed.

Description

technical field [0001] The invention relates to a solar battery silicon wafer, in particular to a semi-automatic insertion machine for PE process. Background technique [0002] In the production process of crystalline silicon solar cells, the PE process for making silicon nitride thin films is an important link. In the existing process, the silicon wafers after the PE process need to be inserted into the flower basket, because there is chromatic aberration in the coating process of the PE process. The bad chips need to be selected, and at the same time, as long as there is a slight friction on the coated side of the silicon wafer after coating, scratches will occur, so most manufacturers choose to insert the chips manually; at the same time, due to the actual design of the flower basket (such as figure 1 shown), each time the operator inserts the wafer, the operator must align the silicon wafer with the corresponding four card points (1) (2) on the same vertical plane in the...
