[0024] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-2This embodiment provides a vacuum adsorption device, including: a device body 1; a vacuum component 2 connected to the device body 1; a connecting tube 3, one end of the connecting tube 3 is detachably connected to the device body 1, and the other end of the connecting tube 3 is provided with a protrusion 31; a suction cup 4, one end of the suction cup 4 is provided with a recessed portion 421, and the other end of the suction cup 4 has a square cross-sectional shape, one end of the suction cup 4 is connected to the outside of the other end of the connecting tube 3, and the recessed portion 421 and the protrusion 31 are snap-fitted.

[0027] Specifically, the device body 1 is used to carry the vacuum component 2, the connecting tube 3, etc.; the vacuum component 2 is used to evacuate the air, so that the suction cup 4 can absorb the thin-walled plate-like aviation parts 6, and has good clamping stability. The thin-walled plate-like aviation parts 6 can be made of aluminum, copper, nylon or plastic, etc.; the connecting tube 3 is used to connect the device body 1 and the suction cup 4. Since one end of the connecting tube 3 is detachably connected to the device body 1, it is convenient to disassemble and assemble the connecting tube 3 and the suction cup 4 in time; the suction cup 4 is used to absorb the thin-walled plate-like aviation parts 6. Since the cross-section of the other end of the suction cup 4 is a square, compared with the circle, the positive The square shape is convenient for covering a larger area of ​​the device body 1, thereby facilitating an increase in the adsorption area of ​​the suction cup 4 and the thin-walled plate-like aviation parts 6. The suction cup 4 can be made of soft materials such as silicone and rubber. The number of suction cups 4 is not limited, and preferably there are multiple suction cups 4, and the multiple suction cups 4 are preferably distributed in a rectangular array; since the protrusion 31 and the recessed portion 421 are snap-fitted, it is convenient for one end of the suction cup 4 and the connecting tube 3 to be detachably connected, thereby facilitating timely replacement of the suction cup 4, and it is also convenient for steplessly adjusting the angle of the suction cup 4 when installing the suction cup 4, effectively preventing adjacent suction cups 4 from interfering with each other.

[0028] Further, such as Figure 2 The suction cup 4 includes a suction cup body 41 and a connecting portion 42, each connected to the other. A recessed portion 421 is provided within the connecting portion 42. The suction cup body 41 has a square cross-section, and the connecting portion 42 is connected to the other end of the connecting tube 3. Specifically, the suction cup body 41 is used to absorb thin-walled aircraft components 6; the connecting portion 42 is used to connect the suction cup body 41 to the other end of the connecting tube 3.

[0029] Further, such as Figure 2The suction cup 4 further includes a plurality of grooves 411 disposed on the outside of the suction cup body 41. Along the radial direction of the connecting portion 42, the plurality of grooves 411 are all annular in shape, and along the axial direction of the connecting portion 42, the plurality of grooves 411 are all conical in shape. Specifically, since the plurality of grooves 411 are all conical in shape along the axial direction of the connecting portion 42, the suction cup body 41 facilitates moving the thin-walled plate-like aircraft component 6 a certain distance toward the device body 1 during adsorption, thereby facilitating a strong adsorption of the thin-walled plate-like aircraft component 6. Since the plurality of grooves 411 are all annular in shape along the radial direction of the connecting portion 42, the uniformity of the adsorption of the thin-walled plate-like aircraft component 6 by the suction cup body 41 is increased. The number of grooves 411 is not limited and can be one, two, or the like.

[0030] Further, such as Figure 2 The suction cup 4 further includes an air passage 43 connected to the recessed portion 421. The air passage 43 penetrates the suction cup body 41 and the connecting portion 42. The other end of the connecting tube 3 is connected to the air passage 43. Specifically, the air passage 43 facilitates the formation of a vacuum inside the suction cup body 41, thereby facilitating the suction cup body 41 to absorb the thin-walled aircraft component 6.

[0031] Further, such as Figure 2 The connection between the suction cup body 41 and the connecting portion 42 is an integral molding connection. Specifically, the integral molding connection facilitates the integrity of the suction cup body 41 and the connecting portion 42. The suction cup body 41 and the connecting portion 42 can be integrally molded by injection molding, molding, or the like.

[0032] Further, such as Figure 1 The vacuum assembly 2 includes an air compressor and a vacuum generator 22 that are interconnected. The end of the vacuum generator 22 that is remote from the air compressor is connected to the device body 1. Specifically, the air compressor and the vacuum generator 22 are interconnected via an interface 21 to facilitate the formation of a vacuum, thereby facilitating the suction cup 4 to absorb the thin-walled aircraft component 6.

[0033] Further, such as Figure 1 , further comprising a control valve 5 connected between the end of the vacuum generator 22 away from the air compressor and the device body 1. Specifically, the control valve 5 is used to control the opening and closing of the vacuum component 2, and the control valve 5 can be a ball valve, a butterfly valve, etc.

[0034] Further, such as Figure 1-2 , one end of the connecting pipe 3 is threadedly connected to the device body 1. Specifically, the threaded connection not only facilitates the detachable connection between the one end of the connecting pipe 3 and the device body 1, but also facilitates the good firmness of the connection between the one end of the connecting pipe 3 and the device body 1.

[0035] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention.
