Treatment chuck structure for facilitating negative-pressure adsorption

[0024] Such as Figure 1 to Figure 3 As shown, a suction cup structure for treatment that facilitates negative pressure adsorption includes a hemispherical suction cup body 3, and a hygroscopic body 1 is also arranged in the suction cup body 3, and the hygroscopic body 1 and the suction cup body 3 are connected by a spring 5 connected, and the hygroscopic body 1 and the suction cup body 3 form a detachable connection relationship, the suction cup body 3 is also provided with a negative pressure air bag 9, and the negative pressure air bag 9 is provided with two one-way valves, the negative pressure air bag 9 and The inner cavity of the suction cup body 3 is connected by a one-way valve, and the one-way valve allows the medium to flow from the inner cavity of the suction cup body 3 to the inner cavity of the negative pressure air bag 9, and the other one-way valve communicates with the inner cavity of the negative pressure air bag 9. The cavity and the outside world, and the one-w

[0030] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As shown, as a structural form that is convenient for disassembly and installation of the hygroscopic body 1 and is conducive to the uniform heating of the hygroscopic body 1, a spring seat 4 is also provided in the suction cup body 3, and one end of the spring 5 is fixedly connected to the spring seat 4. The other end of the spring 5 is fixedly connected with a screw seat 2, and the hygroscopic body 1 is connected with the screw seat 2 through a screw 6, and the heating sheet 8 is fixed on the screw seat 2, and the screw seat 2 is located between the heating sheet 8 and the hygroscopic body 1. between. Preferably, after the moisture absorbing body 1 and the screw seat 2 are fixed, the screw 6 is concave relative to the outer surface of the moisture absorbing body 1 .

[0031] As a structural form that facilitates the wearing stability of the suction cup body 3 , the axial dir
