[0052] The rotary adjustment mechanism includes a turntable 4 mounted on a mounting plate 3, and a robotic arm 5 mounted on the turntable 4;
[0053] A conveying mechanism, located below the robotic arm 5, is used to convey packages grasped by the robotic arm 5 outwards.
[0054] In one specific embodiment, the guide rail 2 is provided with a rack 21 for connecting the lifting assembly.
[0055] In one embodiment, the lifting assembly includes a movable seat 6 and a cylinder 7 disposed on the movable seat 6. The lower end of the movable seat 6 is provided with a gear 61 that meshes with the rack 21, and the mounting plate 3 is connected to the transmission end of the cylinder 7.
[0056] In one specific embodiment, the lower end of the movable seat 6 is symmetrically provided with slots 62 that are adapted to the guide rail 2.
[0057] Specifically, the gears can rotate under the drive of a reducer and a drive motor, thereby moving the moving seat along the rack, thus realizing the movement of the robotic arm along the X-axis, and can also move along the Y-axis through a cylinder, so that the robotic arm can accurately grasp and photograph the corners of the package gripping area.
[0058] In one embodiment, a first camera for photographing the package is mounted on the mounting plate 3. Specifically, the first camera is configured to transmit the captured images of the package to the control terminal of the robotic arm to assist the robotic arm in quickly identifying the specific location of the package and achieving precise positioning of the package.
[0059] In one embodiment, the rotation adjustment mechanism further includes a motor 8 for driving the turntable 4 to rotate.

Specifically, the conveyor belt and the conveyor belt drive unit are existing technologies, such as belt conveyors, and their structure and principles will not be described in detail here.
[0069] In one specific embodiment, the other end of the bracket 9 is provided with a support platform 11 for receiving packages.
[0070] When in use, the high-precision gripping device of this utility model can use guide rails, cylinders or turntables to drive the robotic arm to move along the X-axis, move along the Y-axis or rotate circumferentially, according to the needs of shooting or gripping, so as to accurately shoot or grip the package gripping area and its corners.

[0072] Therefore, compared with existing robotic arms, this invention utilizes guide rails, lifting components, and a turntable to assist the robotic arm's movement, enabling it to accurately capture and grasp the corners of the package grasping area. Simultaneously, it effectively avoids potential damage caused by tilting due to its limited axis length, thus improving the utilization rate of the robotic arm. Furthermore, the conveying mechanism of this invention enables the transport of packages, ensuring efficient package grasping.
