Vacuum technology is being used more and more widely, and the most representative application is the vacuum tunnel of the Hyperloop. In the field of non-standard equipment, the most common is the use of vacuum adsorption of the workpiece, to achieve the purpose of taking and releasing the workpiece or fixing the workpiece, and is used for air tightness detection equipment, forming a vacuum environment to complete vacuum attachment and vacuum sputtering.
Vacuum evaporation, as well as vacuum packaging, blister, vacuum pipeline transportation, etc. This paper gives a brief description of the vacuum system by taking and discharging the material with the vacuum sucker of the manipulator.
Composition of vacuum system.
1. Vacuum system schematic diagram The above diagram is a typical schematic diagram of the vacuum system when the robot uses the vacuum suction cup to take and discharge materials. With vacuum opening, vacuum closing, vacuum breaking and blowing work. The main components include bus plate (there are multiple sets of independent use of suction cups), muffler, solenoid valve, throttle valve, vacuum generator, vacuum filter.
The vacuum detection switch is composed of a sucker, a pipe, a pipe joint and other components. Vacuum elements refer to vacuum generators, vacuum filters, vacuum detection switches, suction cups, etc.
2, the role of the three-position five-way solenoid valve is to change the direction of the air flow, respectively, to achieve the function of workpiece adsorption (manipulator fetch), adsorption stop (manipulator return process) and vacuum breaking and blowing (manipulator discharge). Many engineers use two-position three-way or two-position five-way solenoid valves in their designs.
That is, the middle cutoff is omitted, so that the sucker is either in the adsorption state or in the vacuum or blowing state, which will cause problems in some states in practical applications. Of course, the middle position can be omitted in the upper solenoid valve, when the two-position five-way valve (three-position valve to two-position valve) is connected on the left side, the two-position three-way valve is in the right cutoff state.
