The grabbing mechanism comprises a clamping mechanism 1, an intermediate plate 5, a support 6 and a rotating mechanism 7. As shown in fig. 2 and 4, the middle plate 5 has a first surface 501 and a second surface 502 opposite to each other, and the clamping mechanism 1 is fixedly disposed on each of the first surface 501 and the second surface 502. The rotating mechanism 7 is connected with the middle plate 5, and the bracket 6 is arranged on the outer side of the middle plate 5 to support and fix the middle plate 5, the clamping mechanism 1 and the rotating mechanism 7.

As shown in fig. 2, when the gripping mechanism operates, the product 9 is placed on the gripping mechanism 1 of the first side 501 and the gripping mechanism 1 grips the product 9. Then, the intermediate plate 5 and the clamping mechanism 1 carried thereby are rotated by the rotating mechanism 7, as shown in fig. 3, to turn the first face 501 by 180 degrees, as shown in fig. 4.

Releasing the clamping mechanism 1 allows the product 9 clamped by the clamping mechanism 1 on the first side 501 to be released from the channel 61 for subsequent processing, and continues to place the product 9 on the clamping mechanism 1 on the second side 502.

The above operations are repeated to realize alternate and continuous grabbing and overturning of the assembly line products 9, so that the production efficiency is improved.

The number of the clamping mechanisms 1 is not limited, and as many clamping mechanisms 1 as possible may be provided on the side of the intermediate plate 5 as space allows, so that the productivity is further improved.

As shown in fig. 2, in the present embodiment, the product 9 is a rectangular parallelepiped product. It should be understood that the shape of the product 9 is not limited to the shape in the present embodiment, and any shape of the product 9 may be used for the grabbing mechanism of the present invention to perform grabbing operation as long as the product 9 can be clamped by the clamping mechanism 1 and turned over under the driving of the rotating mechanism 7.

In this embodiment, the rotating mechanism 7 is preferably provided as an electric motor, and the rotating mechanism 7 includes a first transmission rod 71, and the first transmission rod 71 is axially provided on the bracket 6, as shown in fig. 6. The motor is fixedly connected with a first end of the first transmission rod 71, and a second end of the first transmission rod 71 protrudes out of the bracket 6, is embedded into the middle plate 5, and is fixedly connected with the middle plate 5. The motor drives the transmission rod 71 to rotate and thereby the intermediate plate 5 to rotate.

In some other alternative implementations, the rotary mechanism 7 may also be provided as a fuel-powered power machine, such as an internal combustion engine or the like.

Further, the grasping mechanism of the present embodiment further includes a brake unit 2, and the brake unit 2 is used to drive the clamping or unclamping of the clamping mechanism 1.

Specifically, as shown in fig. 6, the brake unit 2 includes a second transmission rod 21. The brake unit 21 is movably connected to a first end of the second transmission rod 21, and a second end of the second transmission rod 21 is fixedly connected to the clamping mechanism 1. The brake unit 2 drives the second transmission rod 21 to move so as to drive the clamping mechanism 1 to clamp or release.

In the present embodiment, the brake unit 2 is provided as a cylinder. As shown in fig. 1, the cylinder is fixedly attached to the same side of the first face 501 of the intermediate plate 5 as the rotating mechanism 7. The cylinder can be fixed on the middle plate 5 by welding or screwing.

In some other alternative implementations, the brake unit 2 may also be configured as a reciprocating power machine such as a hydraulic cylinder.

As shown in fig. 1, the clamping mechanism 1 includes a first jaw 11, a second jaw 12, and a link mechanism 13. Wherein, first clamping jaw 11 is connected with brake unit 2, and second clamping jaw 12 sets up with first clamping jaw 11 relatively, and link mechanism 13 movably connects first clamping jaw 11 and second clamping jaw 12. The first clamping jaw 11 moves under the driving of the braking unit 2, and drives the link mechanism 13 to move, so as to drive the second clamping jaw 12 to move along the direction opposite to the moving direction of the first clamping jaw 11, and further realize clamping or loosening.

Specifically, the link mechanism 13 includes a first link 131, a second link 132, and an intermediate lever 133 as shown in fig. 5. The first jaw 11 is movably connected to a first end of the first link 131, the second jaw 12 is movably connected to a first end of the second link 132, and the intermediate lever 133 is movably connected to second ends of the first link 131 and the second link 132.

The braking unit 2 drives the first clamping jaw 11 to move, drives the first connecting rod 131 to rotate, and causes the intermediate rod 133 to drive the second connecting rod 132 to rotate in the direction opposite to the rotating direction of the first connecting rod 131, and further drives the second clamping jaw 12 to move in the direction opposite to the moving direction of the first clamping jaw 11.

For example, the brake unit 2 drives the first jaw 11 to move leftward (leftward in the view of fig. 5, i.e., away from the middle bar 33), and pulls the first link 131 to rotate in the counterclockwise direction. Because the angular momentum of the system is conserved and the first clamping jaw 11, the link mechanism 13 and the second clamping jaw 12 form a symmetrical system, the angular momentum generated by the rotation of the first link 131 will be compensated by the rotation of the symmetrically arranged second link 132 in the clockwise direction, and the second link 132 rotates clockwise, so as to push the second clamping jaw 12 to move to the right (in the same way, the direction of the view of fig. 5 is taken as a reference), and thus the loosening of the clamping mechanism is realized.

The components of the clamping mechanism 1 can be moved in the opposite direction to the above to achieve clamping, and the description is omitted here.

In this embodiment, a clamping mechanism 1 is disposed on each of the first surface 501 and the second surface 502 of the middle plate 5, and the clamping mechanism 1 further includes a trace 134, as shown in fig. 6.

Since the trace 134 fixedly connects the middle traces 33 on the first and

second sides

501 and 502, the first side 501 and the middle trace 133 on the second side 502 move synchronously.

The braking unit 2 on the first surface 501 drives the clamping mechanism 1 on the first surface 501 to clamp or unclamp, and the intermediate rod 133 on the second surface 502 is synchronously driven by the linkage rod 134 to move, so that the clamping mechanisms 1 on the first surface 501 and the second surface 502 are clamped or unclamped simultaneously.

In some other optional implementations, a plurality of clamping mechanisms 1 are disposed on the first side 501 and/or the second side 502, and the linkage bars 134 are correspondingly disposed, so that the grabbing mechanism can grab/flip a plurality of products 9 at the same time, thereby further improving the production efficiency.

The first guide rod 31 and the second guide rod 32 penetrate the first slide plate 141 and the second slide plate 142, and are slidably coupled to the first slide plate 141 and the second slide plate 142. The first clamping jaw 11 is driven by the braking unit 2 to move along the axial direction of the first guide rod 31 and the second guide rod 32, and then drives the second clamping jaw 12 to move along the axial direction, so that the movement of the two clamping jaws is kept on the same straight line, and the clamping stability is not influenced by deviation.

In some other alternative implementations, the guide 3 may be provided as a slide rail, a slide groove, or the like.

The gripping mechanism further comprises a buffer 4, as shown in fig. 1. The buffer 4 is provided on the first surface 501 and the second surface 502 between the first jaw 11 and the second jaw 12.

Wherein every two elastic elements 42 are fixedly connected to one carrier 41. The carrier 41 is provided as a rectangular parallelepiped, and the elastic member 42 is provided as a spring. Thereby, the placement of the product 9 on the cushioning portion 4 is more stable.
