Washing machine

Abstract

The invention discloses a net washing machine which comprises a sealed shell body, a roller conveying mechanism, an upper spraying mechanism, a lower spraying mechanism and a gas exhaust pipeline. The roller conveying mechanism is arranged inside the shell body and used for conveying a net plate. The upper spraying mechanism and the lower spraying mechanism which are used for spraying net washing water are respectively arranged above a net plate moving route and below the net plate moving route. The gas exhaust pipeline is used for discharging evaporated net washing water inside the shell body. Sealed design is used in the shell body of the net washing machine, and working environment pollution caused by evaporation of plate washing water can be effectively avoided. The roller conveying mechanism which is used for conveying the net plate is arranged inside the shell body. The upper spraying mechanism and the lower spraying mechanism are respectively arranged above the net plate moving route and below the net plate moving route, so that quick and continuous washing of a plurality of net plates can be achieved, and the angle of spraying can be adjusted to improve washing effects so as to avoid secondary manual washing.

Description

technical field [0001] The invention relates to a screen cleaning device, in particular to a screen washing machine. Background technique [0002] At present, in the circuit board manufacturing industry, the screen is usually cleaned manually or by a vertical screen washing machine. When manually washing the screen, the operator needs to wipe the screen with washing water, which is labor-intensive, low in efficiency, and poor in cleaning effect. And the net washing water is an organic solvent, which is easy to volatilize, has a pungent smell, and has a poor working environment. The vertical screen washing machine is to fix the plate vertically into the machine table, and complete the screen cleaning by moving the nozzle up and down. Due to the limited number of nozzles and the limited moving stroke, the vertical screen washing machine has limited cleaning capacity, and once the nozzle appears The clogging problem will cause cleaning dead angles, so after cleaning the scree...

Problems solved by technology

When manually washing the screen, the operator needs to wipe the screen with washing water, which is labor-intensive, low in efficiency, and poor in cleaning effect

And the net washing water is an organic solvent, which is easy to volatilize, has a pungent smell, and the working environment is poor

The vertical screen washing machine is to fix the plate vertically into the machine table, and complete the screen cleaning by moving the nozzle up and down. Due to the limited number of nozzles and the limited moving stroke, the vertical screen washing machine has limited cleaning capacity, and once the nozzle appears The problem of clogging will cause cleaning dead angles, so after cleaning the screen with a vertical screen washing machine, it is necessary to manually clean the screen again, and the cost of cleaning the screen is relatively high
