[0036] In one embodiment, Figure 2-7 As shown, the utility model provides a grasping assembly, including a mechanical arm 100 , a vacuum adsorption head 200 , a lifting seat 300 and a driving structure 400 .

[0037] The vacuum adsorption head 200 is arranged on the robot arm 100. When in use, the robot arm 100 can move with the adsorption head, so as to achieve the purpose of making the adsorption head reciprocate between the discharge end of the conveying assembly 600 and the installation position of the dust cover 700. The vacuum adsorption head 200 is annular, and a plurality of adsorption holes 210 are arranged on the vacuum adsorption head 200. In this embodiment, four adsorption holes 210 are arranged on the vacuum adsorption head 200. The plurality of adsorption holes 210 are arranged in sequence at intervals around the axis of the vacuum adsorption head 200. Preferably, the plurality of adsorption holes 210 are evenly arranged around the axis of the vacuum adsorption head 200. The adsorption hole 210 is a through hole, that is, both ends of the adsorption head are connected to the outside. The first end of the adsorption hole 210 extends to the inner side of the vacuum adsorption head 200, and the second end is connected to the exhaust device. When in use, the exhaust device exhausts air, thereby forming a vacuum degree on the inner side of the vacuum adsorption head 200, so as to achieve the purpose of adsorbing the dust cover 700. Preferably, the first end of the adsorption hole 210 is smaller, because a smaller hole has a larger gas flow rate and thus has a larger vacuum degree, so as to improve the adsorption effect.

[0038] The lifting seat 300 is arranged at the discharge end of the conveying assembly 600, and the lifting seat 300 has a first position and a second position, wherein when the lifting seat 300 is in the first position, the lifting seat 300 is located below the conveying surface of the conveying assembly 600, and when the lifting seat 300 is in the second position, the lifting seat 300 is located above the conveying surface of the conveying assembly 600, thereby lifting the dust cover 700 conveyed by the conveying assembly 600 to the adsorption station. The lifting seat 300 has an arc side wall 310 matching the inner side of the vacuum adsorption head 200, so that when the lifting seat 300 rises to the second position, the outer side wall of the dust cover 700 is closely fitted with the inner side wall of the vacuum adsorption head 200 under the cooperation of the arc side wall 310 of the lifting seat 300 and the inner side wall of the vacuum adsorption head 200, so as to achieve the purpose of making the dust cover 700 be effectively adsorbed by the vacuum adsorption head 200.

[0039] The driving structure 400 is used to drive the lifting seat 300 to reciprocate between the first position and the second position. Specifically, the driving structure 400 is one of a cylinder, an electric push rod, a hydraulic cylinder or a linear electric cylinder. In this embodiment, the driving structure 400 is a linear electric cylinder.

[0040] When in use, the robotic arm drives the vacuum adsorption head 200 to above the discharge end of the conveying component 600, that is, above the lifting seat 300, that is, drives the vacuum adsorption head 200 to the adsorption station. At the same time, the conveying component 600 conveys the dust cover 700 to above the lifting seat 300, that is, the lifting station; thereafter, the driving structure 400 drives the lifting seat 300 from the first position to the second position, and under the action of the lifting seat 300, the dust cover 700 is lifted to the adsorption station, and the exhaust device is started, thereby forming a vacuum on the inner side of the vacuum adsorption head 200.

[0041] During this process, with the cooperation of the arc side wall 310 on the lifting seat 300 and the inner side wall of the vacuum adsorption head 200, the outer side wall of the dust cover 700 is squeezed, so that the outer side wall of the dust cover 700 is deformed, so that the outer side wall of the dust cover 700 and the inner side wall of the vacuum adsorption head 200 can fit tightly, and then the vacuum adsorption head 200 can effectively adsorb the dust cover 700, so as to avoid the dust cover 700 from falling off due to unstable adsorption during the transfer process.

[0042] Preferably, an adsorption groove 220 is provided on the inner side wall of the vacuum adsorption head 200, and the adsorption groove 220 is connected to the first end of at least one adsorption hole 210. Specifically, one adsorption groove 220 may be connected to one adsorption hole 210, or one adsorption groove 220 may be connected to multiple or even all adsorption holes 210. By providing the adsorption groove 220, the purpose of increasing the adsorption area is achieved, and then the purpose of improving the adsorption effect is achieved.

[0043] In one embodiment, the adsorption groove 220 is annular in shape. The adsorption groove 220 of this structure can further expand the adsorption area, thereby achieving the purpose of further improving the adsorption effect.

[0044] Preferably, the adsorption groove 220 is connected to the first ends of all the adsorption holes 210. The annular adsorption groove 220 is connected to all the adsorption holes 210, which can ensure that the vacuum degree of each part of the adsorption groove 220 is basically the same, thereby achieving the purpose of further improving the adsorption effect.

[0045] In one embodiment, a positioning groove 320 for positioning the dust cover 700 is provided on the top of the lifting seat 300. Specifically, the positioning groove 320 matches the inner side wall of the dust cover 700, thereby positioning the inner side wall of the dust cover 700, thereby achieving the purpose of positioning the dust cover 700.

[0046] In one embodiment, a positioning hole 330 is provided on the lifting seat 300, and a positioning rod 500 matching the positioning hole 330 is provided on the robot arm 100. By opening the positioning hole 330 on the lifting seat 300 and providing the positioning rod 500 matching the positioning hole 330 on the robot arm 100, the purpose of positioning the lifting seat 300 is achieved. Preferably, the positioning rod 500 is coaxially arranged with the vacuum adsorption head 200.

[0047] In one embodiment, the utility model further provides a dust cover set device, comprising any one of the above-mentioned grabbing components.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
