[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1-4, this utility model provides a technical solution: including a suction cup assembly 1, an auxiliary anti-fall assembly 2 is sleeved in the middle of the suction cup assembly 1, the suction cup assembly 1 includes a mechanical rocker arm 101, a suction column 102 is fixedly installed on the front of the mechanical rocker arm 101, and a vacuum suction cup 103 is fixedly installed at the bottom end of the suction column 102.

[0022] The auxiliary fall arrestor 2 includes a sleeve plate 201. An installation plate 202 is fixedly installed on the center of the back of the sleeve plate 201. A threaded vertical rod 203 is rotatably installed on the top surface of the installation plate 202. A lifting threaded block 204 is threadedly sleeved on the body of the threaded vertical rod 203. A first rotating seat 205 is fixedly installed on both sides of the lifting threaded block 204. A transmission rod 206 is rotatably installed at the bottom end of the two first rotating seats 205. A sliding rod 208 is inserted through and fixedly connected to one side of the installation plate 202. Sliding sliders 209 are slidably sleeved at both ends of the sliding rod 208. A second rotating seat 207 is fixedly installed on the top surface of the two sliding sliders 209. A linear motor 210 is fixedly installed on the front of the two sliding sliders 209. A clamping plate 211 is fixedly installed on the inner side of the slider of the two linear motors 210.

[0023] In this embodiment, a collar 105 is fixedly sleeved on the column body of the suction column 102, and the sleeve plate 201 is fixedly sleeved on the collar 105.

[0024] Meanwhile, a servo motor 104 is fixedly installed on the front bottom of the mechanical rocker arm 101. The bottom end of the output shaft of the servo motor 104 is fixedly connected to the top end of the threaded vertical rod 203. The two second rotating seats 207 correspond one-to-one with the two transmission rods 206. The top end of the second rotating seat 207 is rotatably connected to the bottom end of the transmission rod 206. The transmission rod 206 can abut against the two sleeve sliders 209 and slide synchronously on the slide rod 208. The sliding of the two sleeve sliders 209 can drive the two linear motors 210 and the clamping plate 211 to move closer to each other and clamp the two sides of the object. The clamping of the object by the two clamping plates 211 can prevent the object from shifting during the process of being picked up and moved by the vacuum suction cup 103, thus improving the stability of the picking up.

[0025] The two clamping plates 211 are arranged symmetrically, and the two transmission rods 206 are arranged symmetrically. Rubber pads are fixedly bonded to the opposite sides of each clamping plate 211 to prevent damage to the surface of the object during clamping.

[0026] When picking up an object, firstly, the mechanical rocker arm 101 is lowered, which in turn lowers the vacuum suction cup 103. The vacuum suction cup 103 is then lowered to the object's suction surface for pickup. Next, the linear motor 210 is activated, controlling the clamping plate 211 to rise and fall, moving it to the center of both sides of the object. Then, the servo motor 104 is activated, causing the threaded vertical rod 203 to rotate. This rotation lowers the threaded lifting block 204, which is threaded onto the vertical rod. The lowering of the threaded block 204 then lowers the first-mounted object fixed to both sides. As the rotating seat 205 descends, the descent of the first rotating seat 205 will cause the top of the transmission rod 206 to descend as well. The transmission rod 206 can then abut against the two sleeve sliders 209, which slide synchronously on the slide rod 208. The sliding of the two sleeve sliders 209 can drive the two linear motors 210 and the clamping plate 211 to move closer together and clamp the two sides of the object. By clamping the object with the two clamping plates 211, it is possible to prevent the object from shifting during the process of being picked up and moved by the vacuum suction cup 103, thereby improving the stability of the suction and reducing the load on the vacuum suction cup 103. It also prevents the object from falling due to the vacuum suction cup 103 failing to pick up the object during the movement, making it more practical.

[0027] In summary, the suction cup device of this packing robot can abut two sliding blocks 209 on the slide bar 208 via the transmission rod 206. The sliding of the two sliding blocks 209 can drive the two linear motors 210 and the clamping plates 211 to move closer to each other and clamp the two sides of the object. By clamping the object with the two clamping plates 211, it can prevent the object from shifting during the process of being picked up and moved by the vacuum suction cup 103, improve the suction stability, reduce the load on the vacuum suction cup 103, and improve the adsorption stability of the vacuum suction cup 103. At the same time, it can also prevent the object from falling due to the vacuum suction cup 103 failing to pick up the object during the movement, and prevent the object from being dropped and damaged during transportation, thus making it more practical.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
