An automatic negative pressure adsorption manipulator

Abstract

An automatic negative pressure adsorption type manipulator comprises a plastic suction cup and a negative pressure mechanism connected to the suction cup, and a triggering elastic sheet is arranged at the lower end of the negative pressure mechanism and is connected to the negative pressure mechanism through contacts on contact connection lines. According to the manipulator, the plastic suction cup is adopted as the adsorption manipulator, the contacts make contact with objects to be lifted for generating pressure when the manipulator descends, a two-position three-way magnetic valve is switched on for opening or closing different channels through pressure, negative pressure is generated inside the suction cup and can adsorb the objects to be lifted, and therefore the ability of lifting the objects can be realized, the manipulator can pick up common parts like a common manipulator and pick up thin-wall parts easily deformed and various parts with irregular curved surfaces, the contact area is increased through the negative pressure adsorption mode, the thin-wall parts are stressed on larger surfaces, partial stressing on the parts is reduced, the parts are protected against damage, and the original structural shapes of the parts can be guaranteed.

Description

technical field [0001] The invention relates to a manipulator, in particular to an automatic negative pressure adsorption manipulator. Background technique [0002] At present, most of the various manipulators on the market use the clamping method to move objects. Due to the instability of the clamping force, when clamping thin-walled parts, it is easy to cause the parts to deform, thereby destroying the original shape and structure of the parts; For parts with irregular curved surfaces, the shape of the curved surface of the part may be damaged due to the effect of contact stress, resulting in the scrapping of the part and bringing considerable losses to the enterprise. Contents of the invention [0003] In order to avoid the disadvantages of the above situation, the present invention provides an automatic negative pressure adsorption manipulator, which uses the negative pressure in a large area to generate pressure to pick up such parts, so as to ensure that the parts ar...
