[0002] Alumina is an inorganic compound widely used in multiple industries, which has a white amorphous powder or crystalline appearance and delicate texture. As a material widely used in multiple industries, the choice of packaging method for alumina powder is crucial for ensuring product quality, transportation safety, and operational convenience. Ton bags can hold from a few hundred kilograms to more than a ton of material, making them ideal for large-scale alumina powder transportation and storage. Compared to small packaging, ton bags can more effectively utilize warehouse or transportation space, reducing unit costs. However, when alumina powder is packaged in ton bags now, workers manually place the ton bag over the discharge pipe of the packaging machine. The clamping mechanism of the packaging machine clamps and fixes the ton bag opening, and finally the packaging machine fills the ton bag with alumina powder.

[0020] The reference signs in the drawings of the specification include: connecting piece 301, suction cup 302, light supplementing lamp 303, clamping rod one 304, clamping plate 305, clamping air cylinder 306, clamping plate 307, visual sensor 308, mechanical arm 309.

[0021] The embodiment is basically as shown in the accompanying Figure 1 and accompanying Figure 2 :

[0022] A mechanical arm hand claw of a ton bag automatic packaging production line, comprising a connecting piece 301, a pickup assembly, a clamping assembly and a controller.

[0023] The connecting piece 301 is in the shape of a trapezoid, the inclined surface of the connecting piece 301 is used for movably connecting with the mechanical arm 309, the connecting piece 301 is rotated at any angle through the mechanical arm 309, the lower surface of the connecting piece 301 is fixedly connected with the light supplementing lamp 303, and the light supplementing lamp 303 is electrically connected with the controller.

[0024] The pickup assembly comprises a connecting rod, the connecting rod is transversely fixedly connected to the lower surface of the connecting piece 301, a plurality of suction cups 302 are fixedly connected to the connecting rod, the suction cup 302 of the suction cup 302 is downward, and the suction cup 302 is provided with negative pressure by a gas pump.

[0025] The clamping assembly comprises two mirror-symmetrical clamping rods I 304, one end of each of the two clamping rods I 304 is fixedly connected to the two side edges of the connecting piece 301, the end away from the connecting piece 301 of each of the two clamping rods I 304 is fixedly connected with a vertically arranged clamping plate 305, the two clamping plates 305 face each other, the side away from each other of the two clamping plates 305 is fixedly connected with two clamping air cylinders 306, the two clamping air cylinders 306 are located at the upper part of the clamping plate 305, the output shaft of the clamping air cylinder 306 transversely penetrates through the clamping plate 305 and is located at the other side of the clamping plate 305, the output shaft of each clamping air cylinder 306 is fixedly connected with a clamping plate 307, and the bottom end of each clamping plate 307 is outwardly bent.

[0026] The controller is electrically connected with the mechanical arm 309 and the air pump, and an electrical signal is connected to the visual sensor 308 (a structured light projector) on the controller. The visual sensor 308 is used for positioning the ton bag and transmitting the position signal of the ton bag to the controller.

[0027] The specific implementation process is as follows:

[0028] In use, the visual sensor 308 first photographs and positions the ton bag on the supporting plate of the feeding bin, and then transmits the signal to the controller. At this time, the controller controls the mechanical arm 309 to drive the connecting piece 301 to move to the top of the ton bag, and then controls the connecting piece 301 to move downward through the mechanical arm 309 until the suction cup 302 contacts the bag opening of the ton bag. At this time, the controller controls the air pump to operate so that the suction cup 302 generates negative pressure to suck the bag opening of the ton bag. After the ton bag is sucked by the suction cup 302, the connecting piece 301 moves upward under the action of the mechanical arm 309. At this time, the part of the bag opening of the ton bag that is sucked is pulled upward, and the part that is not sucked naturally falls downward under the action of gravity so that the bag opening faces the bag supporting device. After the supporting rod of the bag supporting device is inserted into the bag opening of the ton bag and the bag opening is opened to form a rectangular shape, the air pump stops operating so that the suction cup 302 no longer generates negative pressure. The mechanical arm 309 drives the connecting piece 301 to rotate so that the two clamping rods I 304 are located on the same vertical plane. The controller controls the output shaft of the clamping air cylinder 306 to elongate so that a gap with a certain distance is formed between the clamping plate 305 and the clamping plate 307. The mechanical arm 309 operates to drive the two clamping plates 305 to move through the connecting piece 301 and the clamping rod I 304. The gap between the two clamping plates 305 and the two clamping plates 307 is inserted into the upper edge and the lower edge of the bag opening of the ton bag that is supported and opened. At this time, the controller controls the output shaft of the clamping air cylinder 306 to contract. When the output shaft of the clamping air cylinder 306 contracts, the clamping plate 307 moves toward the clamping plate 305. Until the clamping plate 307 and the clamping plate 305 firmly clamp the bag opening of the ton bag, the supporting rod of the bag supporting device is withdrawn from the bag opening of the ton bag. The controller controls the mechanical arm 309 to drive the connecting piece 301 to move so that the bag opening of the ton bag is sleeved on the discharge pipe of the packaging machine.
