[0001] The present application relates to the technical field of clamping devices, in particular to a clamping mechanism and a clamping device. BACKGROUND

[0002] With the development of automation industry, various kinds of automation equipment replace manual operation, from manual operation to automatic production. However, the industry has higher and higher requirements for automation equipment, not only considering the production process, but also considering cost reduction and quality improvement. Especially in the wine industry, it is still in the stage of manual operation or semi-mechanical operation, with high production cost and low automation degree.

[0003] In the conventional technology, in order to improve the automation degree of production, a clamping mechanism is often used to clamp multiple products to complete the carrying or placing of multiple products.

DETAILED DESCRIPTION

[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0035] In the related art, in order to realize the unloading and taking of the stored multiple products by the clamping mechanism, for example, when the clamping mechanism is a mechanical hand, multiple mechanical hands are usually used to clamp one product respectively, which results in high production cost, so one mechanical hand is usually used to clamp one product at a time and execute multiple times, thereby completing the carrying or placing of multiple products. However, this results in low efficiency of the carrying or placing of the products, thereby being not conducive to saving time and reducing production cost.

[0036] The embodiments of the present application will be described below with reference to Figures 1 to 8 .

[0037] According to the embodiments of the present application, on the one hand, a clamping mechanism is provided, such as Figures 1 to 8As shown, the clamping mechanism of the structure includes a first driving assembly 1 and a clamping assembly 2.

The first fixed end 121 is mounted on the first rack 11, and the first execution end 122 rotates in the horizontal plane. The clamping assembly 2 includes a first connecting piece 21 and a plurality of plate pieces. The first connecting piece 21 is in transmission connection with the first execution end 122. The plate pieces are in connection with the first connecting piece 21. Any plate piece is mounted below the first connecting piece 21 along the height direction, and the plate pieces are arranged at intervals.

[0038] Specifically, the clamping mechanism provided in the embodiment is not limited to the clamping product. In accordance with the actual situation of the wine production industry, the product mentioned in the embodiment can be any one of a bottle cap, a bottle body or a packaging box.

[0039] In the embodiment, the first rack 11 is made of profiled material, such as a plurality of aluminum profiles connected to form the first rack 11. In this way, the weight of the first rack 11 can be reduced, and the weight of the clamping mechanism as a whole can be reduced, so that the clamping mechanism is more portable when moving under external force.

[0040] The clamping mechanism with the above structure is in transmission connection between the first execution end 122 of the first driving motor 12 and the first connecting piece 21, and the plurality of plate pieces are connected with the first connecting piece 21. The first execution end 122 rotates in the horizontal plane, so that the first execution end 122 can drive the first connecting piece 21 to rotate in the horizontal plane when the first execution end 122 rotates. In addition, the limiting piece that is spaced apart from the first connecting piece 21 and rotates in unison is additionally provided.

As another embodiment, the first connecting member 21 is provided with a waist-shaped hole. The position of the second connecting member 22 in the waist-shaped hole is adjusted, and then the second connecting member 22 is connected with the second plate member 25 by using the fastener 23, thereby adjusting the distance between the second plate member 25 and the first plate member 24.

[0049] Further, in other embodiments, the position of the first plate member 24 can also be adjusted.

[0050] It should be noted that in the above embodiments, the second direction is arranged perpendicularly to the first direction in the horizontal plane.

[0051] In one embodiment, the first connecting member 21 is provided with a rotating portion; the clamping assembly 2 further comprises a transmission member 26, an inner wall of the transmission member 26 is adapted to the first execution end 122 and is sleeved on the outer wall of the first execution end 122, and an outer wall of the transmission member 26 is arranged in the rotating portion of the first connecting member 21 and is limitingly connected with the inner wall of the rotating portion; under the action of the first driving motor 12, the first execution end 122 drives the transmission member 26 to rotate, and the transmission member 26 drives the first connecting member 21 to rotate so as to drive any plate member to move towards the adjacent plate member.

[0052] In one embodiment, any plate member is arranged along the first direction; a plurality of first connecting members 21 are arranged along the first direction, the transmission member 26 is arranged at the rotating portion of one of the first connecting members 21, and the rotating portions of the remaining first connecting members 21 are rotatably connected with the first rack 11 and constitute limit members.

[0053] Specifically, in the present embodiment, the extension direction of the length of the plate member is the first direction, and at this time, a plurality of first connecting members 21 are arranged along the first direction, which can make the plate member move more stably.

[0054] The clamping mechanism of the structure, by arranging a plurality of first connecting members 21 along the first direction, arranging the transmission member 26 connected with the first execution end 122 at the rotating portion of one of the connecting members, and rotatably connecting the rotating portions of the remaining first connecting members 21 with the first rack 11, so that in the process of the first execution end 122 driving one of the connecting members to rotate, that is, in the process of the distance between any plate member and the adjacent plate member changing, since a plurality of first connecting members 21 are connected with the plate member, the plate member will drive the remaining first connecting members 21 to rotate, so that when a plurality of products are clamped at the same time, the degree of clamping of each product is close or even consistent, and the clamping ability of the clamping mechanism is more reliable.

[0055] In one embodiment, the second driving assembly 3 is further included. The second driving assembly 3 comprises a second driving motor 31, a second rack 32 and a transmission structure 33. The second driving motor 31 is provided with a second fixed end 311 and a second execution end 312. The second fixed end 311 is fixedly installed on an external rack. The second rack 32 is installed above the first rack 11. The transmission structure 33 comprises a rack 332 and a gear 331. The rack 332 is fixedly connected with the second rack 32. The extension direction of the rack 332 is arranged in parallel with the vertical direction.

The second rack 32 fixedly connected with the rack 332 moves along the vertical direction. The first rack 11 connected with the second rack 32 moves along the vertical direction.
