[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Example 1

[0034] like Figure 1-Figure 5 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a gripper capable of grasping two types of material boxes, comprising a mounting bracket 1 and a rotating docking member 2 rotatably connected thereto, the rotating docking member 2 being provided with a docking groove, the mounting bracket 1 being connected to a connecting bracket 3, and the connecting bracket 3 being connected to a mounting plate 4 at one end away from the mounting bracket 1;

[0035] The mounting plate 4 is connected to several positioning parts 5, the mounting plate 4 is connected to several pneumatic components 6, the mounting plate 4 is connected to a small pneumatic component 7, the structure of the small pneumatic component 7 is the same as that of the pneumatic component 6, the bottom of the mounting plate 4 is connected to a vacuum cavity 8, and the bottom of the vacuum cavity 8 is connected to an adsorption part 9.

[0036] The pneumatic component 6 includes a pneumatic housing 601 connected to the mounting plate 4. Two pneumatic connectors 602 are connected to the top of the pneumatic housing 601. A butt connector 603 is connected to the side of the pneumatic connector 602. A driven telescopic rod 605 is provided in the pneumatic housing 601.

[0037] Furthermore, a pneumatic telescopic rod 604 is provided in the pneumatic housing 601, and the pneumatic telescopic rod 604 is connected to one of the two air pressure joints 602. The output end of the pneumatic telescopic rod 604 is connected to a connecting piece 606, and the end of the connecting piece 606 away from the pneumatic housing 601 is connected to an adsorption plate 607, and the adsorption plate 607 is provided with several negative pressure holes 608. The driven telescopic rod 605 is connected to the connecting piece 606.

[0038] Several positioning members 5 are provided with positioning holes, and several positioning members 5 are evenly spaced on the mounting plate 4; the small pneumatic components 7 and the pneumatic components 6 are perpendicularly distributed to each other, and the mounting plate 4 is provided with weight-reducing hollowing.

[0039] The mounting bracket 1 is provided with a rotation groove, and a bearing is provided in the rotation docking member 2 , and the bearing is rotatably connected to the mounting bracket 1 .

[0040] The specific working principle is: this device can effectively improve the efficiency and stability of handling and grasping of packaging boxes. Compared with traditional devices, this device uses a dual method of clamping and adsorption to carry out transportation, thereby improving the grasping stability of this device.

[0041] When the device is in use, the rotatable docking member 2 on the mounting bracket 1 is connected to an existing structure such as a manipulator, thereby achieving a flexible movement effect of the device.

[0042] When the device is used for transportation, for lighter packaging boxes, the device can achieve the adsorption connection effect of the device through the combination of the vacuum chamber 8 and the adsorption member 9 at the bottom, so that large and lighter packaging boxes can be transported.

[0043] When the device needs to be clamped and transported, the transport and clamping effect of the device can be achieved by combining multiple groups of pneumatic components 6. At this time, the pneumatic telescopic rod 604 can be controlled by the pneumatic joint 602. When the inside of the pneumatic joint 602 is under high pressure, the pneumatic telescopic rod 604 extends outward, thereby achieving the effect of clamping the side of the packaging box. At the same time, the driven telescopic rod 605 can limit the sliding trajectory of the connecting piece 606, thereby preventing the connecting piece 606 from tilting.

[0044] When the connecting piece 606 slides outward, the other air pressure connector 602 is in a negative pressure state. The negative pressure state can enable the negative pressure hole 608 on the surface of the adsorption plate 607 to be in a negative pressure adsorption state through the pressure air pipe, thereby enabling the device to achieve the effect of adsorbing the side surface of the packaging box while clamping.

[0045] Example 2

[0046] like Figure 1-Figure 5 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above-mentioned embodiment 1, the gripper that is compatible with grabbing two types of material boxes also includes: the driven telescopic rod 605 is hollow inside, and a pressure air pipe is provided in the driven telescopic rod 605, one end of the pressure air pipe is connected to the air pressure joint 602, and the other end of the pressure air pipe passes through the driven telescopic rod 605 and the connecting piece 606 and is connected to the adsorption plate 607, and the connecting bracket 3 is triangular.

[0047] The specific working principle is: this device can effectively improve the anti-slip effect compared to the traditional single clamping and grasping handling device. At the same time, this device uses adsorption to avoid problems such as damage to the surface of the packaging box caused by excessive squeezing and clamping, thereby improving the protection effect of this device on the surface of the packaging box.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
