Solar cell optical injection feeding and discharging device

Abstract

The invention discloses a solar cell optical injection feeding and discharging device, and relates to the technical field of solar cell production. The solar cell optical injection feeding and discharging device comprises a feeding mechanism and a discharging mechanism; the feeding mechanism comprises a feeding opening 1, a material box 2, an air knife 3, a conveying rail 4, a suction cup 5, a cylinder 6, a feeding servo motor 7, a feeding linear module 8, a temporary storage box 9, a safety optical grating 10, a jacking mechanism 11, a temporary storage linear module 12 and a feeding platform13; and the discharging mechanism comprises a discharging conveying rail 21, a correcting mechanism 22, a suction cup 23, a safety optical grating 24, a discharging box 25, a servo motor 26, a linearmodule 27 and a receiving box 28. By means of an optical injection furnace which can be installed in a matched mode or an independent mode, flexible and soft production can be achieved, rapid operation of an optical injection furnace belt can be adapted, uninterrupted production can be achieved, faults such as double-piece, piece dropping and piece jamming caused by adhesion of cell pieces can beeffectively prevented, continuous operation of the optical injection furnace cannot be affected, and safety of workers can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of solar cell production, in particular to a solar cell light injection loading and unloading device. Background technique [0002] The light injection process is an important process in battery production. Most of the light injection furnaces are integrated between the sintering and testing and sorting processes, and there is no separate loading and unloading mechanism. The optical injection furnace integrated in the entire production line has certain limitations, the utilization rate is not high, and the production of the normal production line is affected when the finished product is reworked. The light injection furnace installed separately has the advantages of flexibility and convenience, and can be produced at any time, and can also be stopped at any time, which is especially convenient for the production of products that require batch rework. [0003] For the separately installed optical injection f...

AI Technical Summary

Problems solved by technology

[0003] For the light injection furnace installed separately, there is no mature loading and unloading device at present. Manual loading and unloading will easily lead to product defects such as scratches on the product appearance, missing corners, and hidden cracks, resulting in an increase in product failure rate.

[0004] In general, the existing manual loading and unloading device does not match the production capacity of the optical injection furnace, which cannot meet the requirements of rapid production of optical injection, and has the disadvantage of high fragmentation rate, which easily leads to product scratches
