Background

The mainstream in the market is generator type vacuum chuck and vacuum pump type vacuum chuck, wherein, generator type vacuum chuck simple structure, spare and accessory parts are popularized, and maintenance and manufacturing are very convenient. But because the generator is converted from positive pressure to negative pressure by compressed air. The conversion rate is low, and the energy consumption is the highest one of all vacuum sources. The generator is influenced by the structure, and the phenomenon that parts are easy to fly is easily caused when the generator is used for re-cutting machining because the sealing strip sucks cutting fluid to cause large fluctuation of negative pressure. The vacuum pump type vacuum sucker passes through small-aperture adsorption holes densely distributed on the disc surface, the vacuum main pipeline negative pressure is 2-3 times larger than the flow of the small-aperture adsorption holes, and when cutting fluid is used for processing, a large amount of cutting fluid is sucked into the adsorption holes, so that great burden is caused to a vacuum pump. The inadvertent discharge of water can cause the vacuum pump to suck too much water and damage the vacuum pump.

Both generator type vacuum chuck and vacuum pump type vacuum chuck consume excessive energy at the cost of great negative pressure loss, resulting in great energy waste, and once a fault occurs, the maintenance is also extremely difficult, so a new scheme is needed to solve the above problems.
