[0019] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0020] like Figure 1 、 Figure 2The unpacking room clamping device shown includes a bracket 1, with sponge suction cups 2 symmetrically arranged on both sides of the center of the bracket 1. The sponge suction cups 2 use a vacuum device to absorb and transfer materials with flat surfaces. A claw structure is symmetrically connected to each end of the bracket 1. The claw structure includes a housing 7, and claws 9 are connected to the housing 7 via a connecting rod group. Each housing 7 is connected to the bracket 1 via a screw rod 6. Each screw rod 6 is connected to a servo motor 5 via a gear box 4. The gear box 4 is fixed to the bracket 1. The servo motor 5 drives the rotation of the gears in the gear box 4 and the screw rod 6. A connecting block is provided in the housing 7 and connected to the screw rod 6, allowing the housing 7 to move back and forth along the screw rod 6.

[0021] like Figure 3 、 Figure 4 As shown, each claw structure includes two symmetrically arranged claws 9, the bottom of each claw 9 is curved in an arc shape, and the two claws 9 symmetrically form a circle. The claws 9 are connected to the shell 7 through a pin shaft, and the connecting rod group includes two symmetrically arranged connecting rods 13. One end of each connecting rod 13 is connected to the piston rod of the cylinder 8 through a pin shaft. The cylinder 8 is arranged at the top of the shell 7, and the other end is connected to the end of the claw 9 on the same side through a pin shaft. A first limit block 15 is provided on the shell 7 below the piston rod, and a second limit block 13 is provided on the outside of each claw 9. The lifting and lowering of the piston rod of the cylinder 8 causes the connecting rod group to drive the opening and closing of the claws 9 to realize the grabbing and transfer of materials with uneven surfaces. A contact plate 11 is also connected to the shell 7, and a first proximity switch 12 is connected to the contact plate 11. When the first proximity switch 12 detects that there is material on the claw 9, it can trigger the start of the moving device of the bracket 1.

[0022] A second proximity switch 3 is provided on one side of the sponge suction cup 2. When the sponge suction cup 2 is adsorbed and the second proximity switch 3 is able to detect the material, it can trigger the start of the moving device of the bracket 1.

[0023] The claws 9 and the contact plate 11 are provided with nylon blocks at the bottom. The nylon blocks are provided on the side in contact with the material to prevent the metal claws and the contact plate 11 from scratching the material. The surface of the nylon blocks can be provided with anti-slip patterns to increase friction.

[0024] Both sides of the housing 7 are connected to the bracket 1 via slide rails 10 so that the housing 7 can remain stable during movement.

[0025] A first accordion cover 16 is provided outside the screw rod 6 , one end of the first accordion cover 16 is connected to the gear box 4 , and the other end is connected to the corresponding housing 7 .

[0026] The slide rail 10 is provided with a second accordion cover 17 . Two second accordion covers 17 are provided on the front and rear sides of the shell 7 . One end of the second accordion cover 17 is connected to the bracket 1 through a connecting block, and the other end is connected to the shell 7 .

[0027] The setting of the accordion cover can prevent dust from entering and causing jamming.

[0028] The utility model has a reasonable and ingenious structural design, which integrates the two material-retrieving structures of grabbing and sucking on the same bracket, simplifies the overall structure, and ensures multiple material-retrieving methods, avoiding entanglement caused by complicated lines and damage to the machine.
