Description

Technical Field

[0001] This utility model relates to the field of robot gripper technology, and more particularly to industrial robot grippers. Background Technology

[0002] With the continuous development of technology, the application of robots in modern industry is becoming more and more widespread. Industrial robots can replace employees to realize the mechanization and automation of production, and improve the efficiency of factory production and processing. Traditional industrial robots are set with an integrated gripper, which is used to pick up and place items.

[0003] In use, most existing technologies employ a single gripping structure to hold items. When gripping a large number of materials, the gripping structure can only grasp the middle of the material, which will cause the material to shake during transportation. Furthermore, existing devices cannot easily adjust the gripping angle for materials that are difficult to hold. Therefore, we proposed an industrial robot gripper. Utility Model Content

[0004] The purpose of this invention is to provide an industrial robot gripper that solves existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial robot gripper includes a robotic arm. A mounting box is fixedly installed on the top of the robotic arm. Multiple mounting frames are fixedly installed on one side of the mounting box. Two gripping arms are rotatably mounted on the inner side of the mounting frames. A flexible anti-slip pad is fixedly installed on one side of each gripping arm. An electric telescopic rod is fixedly installed on the inner wall of one side of the mounting box. A control board is fixedly installed at the output end of the electric telescopic rod. Multiple sliding rods are fixedly installed on one side of the control board. A moving block is fixedly installed on the outer side of one end of each sliding rod. Multiple connecting rockers are rotatably mounted on the outer side of each moving block. The connecting rockers are rotatably connected to the gripping arms.

[0007] As a further improvement to the above solution, a fixing box is fixedly installed on one side of the mounting box, a first motor is fixedly installed on the inner wall of one side of the fixing box, and a bidirectional lead screw is fixedly installed at the output end of the first motor.

[0008] As a further improvement to the above solution, two movable plates are threaded on the outer side of the bidirectional lead screw, and a second motor is fixedly installed on one side of the movable plates.

[0009] As a further improvement to the above solution, a drive shaft is fixedly installed at the output end of the second motor, and a clamping rotating disk is fixedly installed on one side of the drive shaft.

[0011] As a further improvement to the above solution, two rotating slots are provided on the upper part of the mounting frame, and the clamping arm is rotatably mounted on the inner side of the rotating slots.

[0012] As a further improvement to the above solution, a connecting groove is provided above the moving block, the connecting rocker arm and the clamping arm, and a pin is provided on the inner side of the connecting groove.

[0013] As a further improvement to the above solution, the flexible anti-slip mat is made of flexible rubber, and anti-slip textures are provided on the top of the flexible anti-slip mat.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) The industrial robot gripper of this utility model can be fixed on the upper part of a mechanical arm that can adjust the clamping angle. When it is necessary to clamp the material, the first motor can be controlled to drive the bidirectional lead screw to rotate. The bidirectional lead screw can drive the moving plate to move in the opposite direction through the thread engagement. The moving plate can drive the clamping rotating disk to clamp and fix the material on both sides. At this time, the second motor is controlled to drive the drive shaft and the clamping rotating disk to rotate, which can drive the material to rotate at an angle. The gripping angle of the device on the material can be adjusted, so that the material can be placed without manual adjustment by personnel.

[0016] (2) After the angle of the material is adjusted, the industrial robot gripper of this utility model can control the electric telescopic rod to drive the control board and multiple sliding rods to move. After sliding, the sliding rod can pass through the inside of the mounting frame and drive the moving block to move. After the moving block moves, multiple connecting rockers above it can follow its movement. The connecting rockers can drive the clamping arm to swing around the mounting frame, allowing the clamping arm to drive the flexible anti-slip pad to clamp the material. The upper part of the flexible anti-slip pad is provided with anti-slip texture, which can make the material have greater friction during the clamping process and make it difficult for it to fall off.
