Water-based type screen cleaning machine

Abstract

The invention discloses a water-based type screen cleaning machine comprising a case main body. A cleaning fluid box, a rinsing fluid box, a pneumatic membrane pump, a water pump, a rinsing fluid filter device and a cleaning fluid filter device are arranged in the lower portion of the case main body. A hot air box, an air blower, a gear transmission device, a pressure regulation filter device, a spray device and a cleaning chamber are arranged in the upper portion of the case main body. All components in the case main body are connected in a simple and reasonable mode through pipelines. A blending device is arranged in the cleaning fluid box. A heating pipe is arranged in the cleaning fluid box and a shell body of the cleaning fluid box is in an interlayer structure. A heating pipe is arranged in the rinsing fluid box and a shell body of the rinsing fluid box is in an interlayer structure. An air knife device is arranged on the spray device, and the air knife device and the spray device can be driven by the gear transmission device to move vertically. After being used, cleaning fluid is recycled or discharged after flowing through the cleaning fluid filter device. After being used, rinsing fluid is recycled or discharged after flowing through the rinsing fluid filter device. The water-based type screen cleaning machine is easy to operate, good in cleaning performance, safe and environmental-friendly.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a water-based screen cleaning machine used in the surface mounting technology of an electronic manufacturing industry and used for cleaning residues in the pre-treatment or post-processing of the screen. Background technique [0002] In the electronics manufacturing industry, it is often necessary to print solder paste on the PCB for patching and soldering. This process requires the use of stencils, which are essential basic supplies for the SMT (Surface Mount Technology) industry. In the SMT industry, in order to eliminate corrosion, prevent electrostatic damage, improve the service life of products, and better meet the high-quality and high-reliability requirements of customers, it is necessary to effectively remove the flux residue and solder paste on the surface of the stencil. , Solder balls, impurities, dust, oil stains and other harmful residues are washed away. At present, the common...

AI Technical Summary

Problems solved by technology

In addition, with the miniaturization of electrical components, the mesh holes of the screen printing steel are becoming smaller and smaller, and solder paste or ink is more likely to remain in the mesh holes and it is difficult to clean them. These residues will directly lead to poor printing. higher requirements

At present, most of the existing stencil cleaning machines have shortcomings such as insufficient cleaning, insufficient cleaning liquid hydraulic pressure, incomplete drying, complicated operation, and non-recyclable cleaning liquid.
