Back plate cleaning assembly capable of avoiding raised dust

Abstract

The invention relates to a back plate cleaning assembly capable of avoiding raised dust. The assembly comprises an air knife and a dust suction plate, the air knife is fixed to the upper portion of aworktable, the dust suction plate is opposite to an air outlet of the air knife, supporting rib plates are mounted on the two sides of the worktable, the air knife is fixedly mounted between the two supporting rib plates through a bolt, the dust suction plate is fixedly connected with the supporting rib plates through a transverse plate, the dust suction plate comprises an arc baffle sunken towards the air knife, a negative pressure cavity is formed in the bottom end of the arc baffle, a dust suction hole is formed in the side, close to the air knife, of the negative pressure cavity, a dust accumulating plate is arranged opposite to an air outlet of the air knife, foreign matter blown by the air knife can be absorbed on the dust suction plate in time, particularly, the negative pressure cavity in the bottom end of the dust accumulation plate absorbs the airflow blown out of the air knife and foreign matter carried by the airflow in the circulation path into the negative pressure cavity, and crossed pollution of the foreign matter can be prevented.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to an air knife capable of effectively cleaning side walls. Background technique [0002] Electronic products have high requirements on the cleanliness of components, and the general methods of cleaning electronic products include: contact type and non-contact type. Whether it is contact type or non-contact type, it is necessary to neutralize the static electricity on the surface of electronic products first. and or export. [0003] For example, at present, the cleaning of backplanes in backlight modules such as TVs and computers generally adopts the method of connecting the clean air flow containing negative ions to the air knife above the cleaning workbench through the air pipe, from the air outlet of the air knife to the larger Flow out at a high speed, so that the tiny particles and foreign matter on the backplane can be blown off by the wind force, so as to realize ...

AI Technical Summary

Problems solved by technology

[0004] Under normal circumstances, the air knife is fixed, and the backboard passes under the air knife along with the workbench, so that the particles and foreign matter on the backboard are blown off by the high-pressure airflow blown from the air knife; at this time, the airflow direction of the air knife is the same as that of the backboard It is better if the included angle in the forward direction is greater than 90 degrees; this can effectively prevent the foreign matter blown up by the dust from continuing to fall on the cleaned part, but it cannot effectively ensure that the foreign matter blown up by the airflow will flow in the space and continue to fall risk to subsequent backplane
