[0035] First, combine Figures 1-11 This invention describes a fall-prevention mechanical gripper according to an embodiment of the present invention, used for gripping and moving materials.

[0036] like Figures 1-11 As shown, an anti-fall mechanical gripper according to an embodiment of the present utility model includes: a frame 1, a clamping assembly and an adsorption assembly 4;

[0037] The clamping assembly includes: a left clamping mechanism 2, a right clamping mechanism 32, a clamping plate 6, and a fall-prevention support plate 7;

[0038] The left gripper mechanism 2 and the right gripper mechanism 32 are both fixed on the frame 1.

The output ends of the left gripper mechanism 2 and the right gripper mechanism 32 are connected to the gripper plate 6. The left gripper mechanism 2 and the right gripper mechanism 32 drive the two gripper plates 6 to grip the materials from both sides. The lower end of the gripper plate 6 is provided with an anti-fall support plate 7. The anti-fall support plate 7 is located below the materials and is used to support the materials from below.

[0039] The left gripper mechanism 2 and the right gripper mechanism 32 of this application drive the two gripper plates 6 away from each other, so that the adsorption component 4 adsorbs the upper surface of the material. The left gripper mechanism 2 and the right gripper mechanism 32 drive the two gripper plates 6 closer to each other, so that the two gripper plates 6 grip the material. The anti-fall plate 7 is placed below the material, so that the anti-fall plate 7 supports the material from below, preventing the material from falling from the mechanical gripper during the movement of the material, and ensuring the safety of material transportation.

[0040] like Figures 5-9 As shown, the left gripper mechanism 2 includes: an adjusting plate 21, a first slide rail 22, a first slider 23, and a first cylinder 24;

[0041] The first slide rail 22 is fixed on the frame 1, the first slider 23 is slidably disposed on the first slide rail 22, the adjusting plate 21 is connected to the first slider 23, the first cylinder 24 is fixed on the frame 1 and is used to drive the adjusting plate 21 to move on the first slide rail 22, and the adjusting plate 21 is fixed with a gripper plate 6.

[0044] In this embodiment, the first cylinder 24 can drive the adjusting plate 21 to move on the first slide rail 22, realizing the action of gripping and putting down the material. After the adsorption component 4 adsorbs the material, the material support cylinder 25 drives the gripper plate 6 to move downward on the material support slide rail 26, moving the anti-fall support plate 7 below the material, so that the anti-fall support plate 7 supports the material from below.

[0045] like Figures 5-9 As shown, the right gripper mechanism 32 includes: a sliding plate 31, a second slide rail 32, a second slider 33, and a second cylinder 34;

[0046] The second slide rail 32 is fixed on the frame 1, the second slider 33 is slidably disposed on the second slide rail 32, the sliding plate 31 is connected to the second slider 33, the second cylinder 34 is fixed on the frame 1 and is used to drive the sliding plate 31 to move on the second slide rail 32, and a gripper plate 6 is fixed on the sliding plate 31.

[0050] In this embodiment, the mechanical gripper moves to make the vacuum suction cup 41 adhere to the upper surface of the material, and the telescopic rod 43 can prevent the vacuum suction cup 41 from being damaged, so that the material can be adsorbed by the vacuum suction cup 41.

[0051] like Figures 1-4 As shown, it includes positioning component 5;

[0052] The positioning component 5 is used to position the material after it has been gripped by the clamping component.

[0055] In this embodiment, after the mechanical gripper grabs the material, the driving component 51 drives the positioning plate 54 to move on the positioning slide rail 52, so that the positioning push rod 55 pushes the material grabbed by the clamping assembly, so that one end of the material hits one side of the limiting baffle 11, thereby achieving the positioning of the material.

[0056] like Figures 1-4 As shown, the frame 1 is provided with a connecting flange 12, which is used to connect the frame 1.

[0057] The mechanical gripper can be easily connected and fixed via the connecting flange 12.

[0058] In this embodiment, two sets of clamping components and adsorption components 4 are set on the frame 1, so that the mechanical gripper can clamp two materials at the same time, thereby improving the material movement efficiency.

[0059] Above, refer to Figures 1-11 This invention describes a fall-prevention mechanical gripper according to an embodiment of the present invention. The left gripper mechanism 2 and the right gripper mechanism 32 respectively drive the two gripper plates 6 away, causing the adsorption component 4 to adsorb the upper surface of the material. The left gripper mechanism 2 and the right gripper mechanism 32 then drive the two gripper plates 6 closer together, causing the two gripper plates 6 to grip the material. A fall-prevention support plate 7 is placed below the material, supporting it from below and preventing the material from falling off the mechanical gripper during material movement, thus ensuring the safety of material transportation.
