The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The utility model embodiment provides an adsorption mechanism, such as Figure 1-Figure 7 As shown, the adsorption mechanism comprises:

[0033] A top plate 100, the top plate 100 is used for the adsorption mechanism to connect the moving component;

[0034] A support seat 200 and a sliding column 300, wherein the support seat 200 and the sliding column 300 constitute a group of adsorption units, and a plurality of groups of adsorption units are arranged on the end surface of the top plate 100 away from the moving component;

[0035] The support seat 200 includes a primary fixing plate 210 and a secondary fixing plate 220, the sliding column 300 is inserted into the secondary fixing plate 220 and elastically connected to the primary fixing plate 210, the end surface of the secondary fixing plate 220 away from the primary fixing plate 210 is provided with a buffer seat 240, and the side wall of the sliding column 300 is provided with a buffer slope 330 that contacts and connects with the buffer seat 240 during the sliding process;

[0036] In the present application, the adsorption mechanism is mainly moved by a moving component with lifting and translation functions. The moving component here is a multi-axis robot in the prior art, and a suction cup component 400 is arranged at the end of the sliding column 300 away from the support seat 200 in the adsorption unit. The structural principle of the suction cup component 400 is the same as the vacuum suction cup structure of the prior art. The prior art is directly adopted here, and its structure is not described in detail; the suction cup component 400 and the sliding column 300 are connected by threads. The main function of the adsorption unit composed of the support seat 200 and the sliding column 300 is to absorb the vibration generated when the suction cup component 400 contacts the workpiece to be picked up and placed during the process of picking up and placing by the moving component, so as to reduce the damage to the workpiece to be picked up and placed;

[0037] The first-level fixing plate 210 is provided with a spring 230, and one end of the sliding column 300 inserted into the second-level fixing plate 220 is elastically connected to the first-level fixing plate 210 mainly through the spring 230, and the first-level fixing plate 210 is provided with a spring seat 250 on the end surface facing the second-level fixing plate 220, and the spring seat 250 is connected with the spring 230, and the spring seat 250 and the spring 230 are both existing technical structures, and the buffer slope 330 provided on the outer wall of the sliding column 300 will contact and connect with the buffer seat 240 during the deformation and contraction of the spring 230, and the buffer seat 240 is provided with a slope structure adapted to the buffer slope 330, and the part of the buffer seat 240 in contact with the buffer slope 330 is made of soft rubber material. During the energy absorption process of the spring 230, the buffer seat 240 also absorbs the kinetic energy transmitted by the sliding column 300, and the flexible absorption characteristics of the soft rubber material are used to enhance the stability during the shock absorption process, further improve the shock absorption effect, and reduce the damage to the workpiece to be picked up and placed;

[0038] As a preferred implementation in this embodiment, the sliding column 300 further includes a main rod 310, a support ring 320, a buffer slope 330 and a guide slider 340, and the support ring 320, the guide slider 340 and the buffer slope 330 are sequentially arranged on the main rod 310;

[0039] The secondary fixing plate 220 is provided with a sliding hole 221, and the side wall of the sliding hole 221 is provided with a limiting guide groove 222. The main rod 310 extends from the sliding hole 221 to the area between the primary fixing plate 210 and the secondary fixing plate 220.

[0040] The support ring 320 is located on the portion of the main rod 310 that passes through the secondary fixing plate 220. The function of the support ring 320 is to abut against the end of the spring 230 that is away from the primary fixing plate 210.

[0041] The guide slider 340 slides in the limiting guide groove 222 provided on the side wall of the sliding hole 221. The function of the guide slider 340 is to ensure the linearity of the main rod 310 during movement and reduce the deflection of the main rod 310.

[0042] In this example, the buffer slope 330 will be held against the buffer seat 240 during the sliding process of the main rod 310. For example, when the suction cup assembly 400 at the front end of the sliding column 300 contacts the workpiece to be adsorbed and generates vibration, the main rod 310 slides to absorb the vibration energy during the contact process. The buffer seat 240 contacts the buffer slope 330 after the spring 230 is deformed. The buffer seat 240 utilizes deformation to generate an interference fit with the buffer slope 330, absorbs impact energy through deformation, and supplements the spring shock absorption effect to a certain extent, further accelerating the energy dispersion and improving the overall shock absorption effect.

[0043] As a preferred implementation in this embodiment, the buffer seat 240 includes an outer cylinder 24 and an elastic rubber ring 242. The inner wall of the elastic rubber ring 242 is a slope structure and is adapted to the buffer slope 330. The elastic rubber ring 242 can be made of rubber or other soft materials in the prior art. The elastic rubber ring 242 is mainly used to generate a blocking force to absorb impact energy and improve the shock absorption effect.
