Aiming at the deficiencies in the prior art, the utility model provides an improved touch screen etching cleaning line, which can avoid material jams in the cleaning process, improve work efficiency, and reduce production costs.

In order to achieve the above objectives, the present utility model adopts the following technical solutions:

An improved etching and cleaning line for touch screens includes a frame, the surface of the frame is provided with a plurality of rollers for conveying large pieces of touch screen side by side, and the frame is provided with a motor that drives the rollers to rotate. There is a spray pipe for cleaning large touch screens and an air knife for drying the cleaned large touch screens above. The frame is provided with a protective net to prevent the large touch screen from upturning, and the protective net includes a plurality of edges. A protective line with a large moving direction of the touch screen tilted from top to bottom.

As a preferred solution, two partitions spaced apart from the front and rear are provided directly below the air knife, and a cleaning tank is formed between the two partitions that is directly opposite to the air outlet of the air knife. There is a deflector that guides the large touch screen to the cleaning tank, and the deflector extends laterally along the moving direction of the large touch screen.

As a preferred solution, there are multiple spray pipes, and the multiple spray pipes are arranged above the roller at intervals.

As a preferred solution, the protective line extends from the spray pipe closest to the air knife to below the air knife.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, by arranging a protective net on the rack, when the touch screen is upturned during the movement, the protective net can be guided to move without causing any problems. The upturning and jamming improves the cleaning efficiency and avoids downtime for repairs. At the same time, the large touch screen is guided to the cleaning tank by setting the deflector on the rack, so that the large touch screen can be smoothly transferred by the deflector. Air-drying under the air knife will not cause material jams due to the large swaths of the touch screen, which further improves the cleaning efficiency.
