Description

Loading clamp capable of quickly replacing screen printing table-board paper

Technical Field

The utility model belongs to the technical field of loading clamps for screen printing table-board paper, and particularly relates to a loading clamp capable of quickly replacing screen printing table-board paper, which is known by a solar cell.

Background

Screen printing is one of the core procedures in the manufacturing and production process of solar cells, is equipment for printing back aluminum, back silver and front silver on the front side and the back side of a silicon wafer through designed grid line patterns, drying and sintering slurry to form good ohmic contact with the silicon wafer, and forming electrodes for current derivation, wherein the printed cells can be used for solar power generation. The cleanliness of the printing table top directly influences the printing quality of the solar cell.

The main functions of the upper backing paper of the printing table are as follows:

1. the slurry is prevented from polluting the printing table top in the printing process;

2. buffering the suction of vacuum suction on the printing table top to prevent fragments from being generated in the printing process;

3. and the MARK point is easy to capture by a camera, and the silicon wafer printing correction is carried out.

Therefore, the quality of the battery sheet printing is affected once the printing table, particularly the table paper, is contaminated. And cleaning the dirty table board or replacing the dirty table board paper often takes a long time, which can affect the normal production of the production line and the productivity. Therefore, the printing quality of the table paper on the silicon wafer is greatly influenced, at present, the paper changing operation of the printing table is manually carried out, namely, new paper is stuck to a fixed position of the printing table before each shift change or the paper changing operation is judged by experience of an operator, and equipment is required to be stopped for paper changing operation in the process.

The beneficial effects are that:

1. the operation difficulty is simplified, the operation such as paper clamping can be realized in advance on the operation table outside the machine table, and the operation in a narrow space in a narrow machine table is avoided.

2. The tension and fixation of the table paper are realized and the flatness of the table paper for long-term use is ensured by arranging the elastic material between the paper clamping fixture and the hanging point on the buckle.

3. The flexible connection is used among different units of the buckle, the table paper of each sub table board cannot affect each other, and the operation difficulty of staff is reduced.
