3. The cleaning device for the sintering furnace band according to claim 1, characterized in that: the heating pipe is an electric heating pipe, the heating pipe is positioned at the bottom in the middle of the box body, and the two fans are respectively positioned at the two ends of the box body and close to the heating pipe.

4. The cleaning device for the sintering furnace band according to claim 1, characterized in that: the bottom of the box body is provided with rollers.

The technical field is as follows:

The invention relates to the field of solar cells, in particular to a cleaning device for a sintering furnace zone.

background art:

The sintering is a part inseparable from the silk-screen printing process in the production process of the solar cell, the sintering quality also directly influences the silk-screen printing quality, the sintering process mainly forms ohmic contact between positive and negative electrodes subjected to silk-screen printing and a silicon wafer under the action of high temperature, so that the open circuit voltage and the filling factor of the solar cell are improved, and meanwhile, the high temperature in the sintering furnace can promote H generated in the coating process to diffuse into the cell, so that the passivation effect on the solar cell is good, and the conversion efficiency of the solar cell is improved.

In the normal production process, due to the fact that oil stains can be generated in the silicon wafer sintering process, oil stains can be accumulated on a furnace belt, the printed silicon wafer can generate oil stain pieces when contacting the furnace belt, and therefore the battery pieces are degraded and lost, and therefore the furnace belt of the sintering furnace needs to be periodically cleaned. However, the cleaning process is time-consuming and labor-consuming, and the cleaning process needs to be stopped, which greatly affects the productivity.

the invention content is as follows:

The invention aims to solve the technical problem of providing a cleaning device for a sintering furnace belt, which can clean the furnace belt while producing and thus avoid oil stain pieces, can clean the furnace belt without stopping production, greatly saves time, labor and cost, and has great significance for improving the A-grade product rate of battery pieces.

The technical scheme includes that the cleaning device for the sintering furnace zone comprises a box body, the box body is hollow, through holes for the furnace zone to pass through are formed in two ends of the box body, a heating pipe and a fan are arranged in the box body, and the heating pipe and the fan are located below the furnace zone penetrating through the box body.

Preferably, the box body is of a rectangular parallelepiped structure, and the top of the box body is provided with a box cover which can be lifted.

preferably, the heating pipe is an electric heating pipe, the heating pipe is located at the bottom of the middle of the box body, and the number of the fans is two, and the two fans are respectively located at two ends of the box body and close to the heating pipe.

Furthermore, the bottom of the box body is provided with rollers.

Compared with the prior art, the invention has the following advantages after adopting the scheme: by adopting the principle of a thermal shrinkage machine, hot air is formed by electrifying and heating, and the device is arranged behind a furnace belt washing tank, so that the furnace belt can be thoroughly dried by the device after being washed, the idea of producing and washing at any time can be realized, and the production of greasy dirt pieces is avoided. The invention can realize furnace belt cleaning without stopping production, greatly saves time, labor and cost, and has great effect on improving the A-grade product rate of the battery pieces.
