A driving wheel 27 is provided at the bottom of the synchronous motor 26. At least one third driven wheel 22 is provided between the driving wheel 27, the second driven wheel 222, and the first driven wheel 221, and is connected by a synchronous belt 25.

A limiting sheet metal 44 is provided on one side of the first driven wheel 221, and a first photoelectric sensor 410 is mounted around the second driven wheel 222. A fixing plate 28 is fixedly connected to the top of the mounting plate 1. The synchronous motor 26 and an air pipe bracket 43 are fixedly connected to the top of the fixing plate 28. The air pipe bracket 43 is fixedly connected to an air pipe 35, which supplies air to a cylinder 9. A flange 4 is fixedly connected to the top of the adapter shaft 3, and an adapter rib 5 is provided on one side of the adapter shaft 3. The flange 4 is fixedly connected to the robot arm. The first driven wheel 221 drives the rotating claw to rotate through the driven shaft, and the driven shaft is movably connected to the mounting plate 1 through the bearing 2. The robot arm drives the mounting plate to rotate through the adapter shaft 3.

[0021] The rotating gripper 14 includes an adapter plate 13 and a back plate 8 connected by guide posts. A cylinder 9 is fixedly connected to the bottom end of the back plate 8, and a slider 10 is slidably connected to the bottom end of the cylinder 9. An L-shaped pneumatic gripper fingertip 18 is fixedly connected to the bottom end of the slider 10, and a rubber pad 19 is fixedly connected to the inner wall of the pneumatic gripper fingertip 18. A bushing 12 is fixedly connected to the top end of the back plate 8, and a rectangular spring 16 is pressed between the adapter plate 13 and the bushing 12. A second photoelectric sensor 17 is provided at the top end of the back plate 8, and a cover plate 20 is provided on one side of the adapter plate 13. The second photoelectric sensor 17 detects the rotation angle of the pneumatic gripper fingertip 18 to achieve precise control. The rectangular spring 16 prevents damage to the product during the clamping process. The cylinder 9 drives the pneumatic gripper fingertip 18 to precisely clamp the product through the slider 10, and the rubber pad 19 prevents damage to the product surface.

[0022] The second driven wheel 222 is provided with a driven shaft 21. A buckle 211 is engaged at the top of the driven shaft 21. Two baffles 42 are provided at the top of the limiting sheet metal 44. The included angle between the two baffles 42 is 90 degrees. The buckle 211 abuts against the baffles 42. The buckle can rotate 270 degrees. At 0° and 270°, the buckle abuts against the baffle. At the corresponding position, the light-shielding plate 40 is inserted into the first photoelectric sensor 410.

[0023] A light-shielding plate 40 is snapped onto the top of the first driven wheel 221. A bracket 41 is fixedly connected to the top of the mounting plate 1. The top of the bracket 41 is fixedly connected to the first photoelectric sensor 410. The light-shielding plate 40 is rotatably inserted into the first photoelectric sensor 410. There are three first photoelectric sensors 410, which are evenly distributed on a semicircle.

[0024] An idler pulley 23 is provided between the driving pulley 27 and the third driven pulley 22, between two adjacent third driven pulleys 22, between the third driven pulley 22 and the second driven pulley 222, and between the third driven pulley 22 and the first driven pulley 221. The idler pulley 23 meshes with the timing belt 25 and tensions the timing belt. Preferably, the driving pulley 27, the third driven pulley 22, the second driven pulley 222, and the first driven pulley 221 have the same structure and size, and each has a rotating pawl at its bottom. The driving pulley 27 drives the rotating pawl to rotate through each driven pulley, which helps to reduce costs and increase efficiency.

[0025] A synchronous motor controls the synchronous rotation of six independent rotating jaws via a synchronous belt and driven pulley, realizing the rotational action of the mechanical gripper. The fingertips of the cylinder-mounted pneumatic gripper are controlled by the cylinder to extend and retract, clamping the object. The synchronous motor drives the synchronous belt to rotate, which in turn drives the driven pulley to rotate within a 270-degree range. During the rotation of the latch 211, it abuts against the baffle 42. The light-shielding plate 40 is in the same direction as the latch 211, enabling the angle adjustment of the gripper to meet the operational needs of different angles.

[0026] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
