[0002] A manipulator is an automatic operating device that can imitate certain movements and functions of human hands and arms, and is used to grasp, move objects or operate tools according to a fixed procedure. During the production process of disassembling and assembling boxes, the manipulator needs to handle objects of different shapes, such as from regular rectangular boxes to irregularly shaped parts. The original grippers may not be able to adapt well to the gripping of objects of new shapes. At this time, the grippers need to be replaced to adapt to the objects for gripping. And when the wear of the grippers reaches a certain level, the grippers also need to be replaced to ensure the normal operation and gripping effect of the manipulator. However, the existing manipulators and grippers are mostly fixed in one, which means that the manipulator needs to be replaced as a whole when replacing the grippers, which increases its cost of use. In addition, the operation of disassembling and assembling the grippers is cumbersome and inconvenient, which causes the material picking work to be suspended for a long time, affecting normal work efficiency. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] In order to solve the problem that the replacement of the manipulator gripper is cumbersome and inconvenient, affecting the normal production work, please refer to Figures 1-4 The present embodiment provides a material-retrieving robot for box assembly and disassembly production, which can clamp and fix the gripper of the robot arm, so that the appropriate gripper can be quickly replaced when the robot is assembled and disassembled, without the need for long-term downtime for adjustment or waiting for professional technicians to perform complex modifications. The device includes a chassis 1 located in the production and processing area, which is connected to the robot arm and serves as a carrier for carrying the structure set thereon. A clamping assembly 2 for fixing the gripper of the robot arm is provided on the chassis 1, and a receiving assembly 3 for installing the gripper of the robot arm is detachably installed in the clamping assembly 2. A driving assembly 4 for driving the gripper assembly 2 to move is also detachably installed in the chassis 1. When the robot arm is installed, the chassis 1 is installed on the robot arm, and the gripper of the robot arm is installed on the receiving assembly 3. By placing the receiving assembly 3 in the gripper assembly 2, the gripper assembly 2 is driven to move by the driving assembly 4, thereby achieving rapid clamping and fixing of the gripper, so that the appropriate gripper can be quickly replaced when the robot is assembled and disassembled, without the need for long-term downtime for adjustment or waiting for professional technicians to perform complex modifications.

[0027] During the box assembly and disassembly production process, the robot needs to handle objects of different shapes. The original grippers may not be able to adapt well to the gripping of objects of new shapes. In this case, the grippers need to be replaced to adapt to the objects for gripping. And when the wear of the grippers reaches a certain level, the grippers also need to be replaced. The clamping assembly 2 includes a support column 21 with an inner cavity fixedly mounted on the chassis 1. The support column 21 serves as a carrier to support and protect the structure set therein, reducing the impact of the external environment on it. A rotating shaft 22 is rotatably mounted in the support column 21. A plurality of protrusions 23 uniformly arranged along the surface shape of the support column 22 are fixedly connected to the rotating shaft 22. The protrusions 23 are meshed with a worm 24 rotatably mounted on the inner wall of the support column 21. The worm 24 is used to drive the rotating shaft 22. A rotating disk 25 is fixedly connected to the support column 21. The rotating disk 25 is provided with three groups of slide grooves 26 along a circular array. The slide grooves 26 are used to limit the sliding of the slider 29. The support column 21 is provided with a mounting hole for connecting the receiving component 3 and three groups of sliding grooves 27 along a circular array. The sliding grooves 27 are used to limit the movement of the clamping block 28. A clamping block 28 is slidably connected in the sliding groove 27, and the clamping block 28 is used to clamp the connecting column 32. A slider 29 slidably installed in the sliding groove 26 is fixedly connected to the clamping block 28, and the slider 29 is used to drive the clamping block 28 to slide. The receiving component 3 includes a mounting plate 31, and the mounting plate 31 is used to install the clamping claw. A connecting column 32 that is detachably installed in the mounting hole is fixedly connected to the mounting plate 31, and the connecting column 32 is used to connect the clamping component 2. Before the robotic arm is installed and used, the clamping claw is installed on the mounting plate 31, and the chassis 1 is installed on the robotic arm. Then, the mounting plate 31 with the clamping jaws aligns the connecting column 32 with the mounting hole of the support column 21, and rotates the drive assembly 4, which drives the worm 24 to rotate, and the rotating disk 25 to rotate through the transmission of the protrusion 23. Under the rotation of the worm 24, the slider 29 slides within the slide groove 26. Under the sliding of the slider 29, the clamping block 28 slides closer to or away from the connecting column 32 in the mounting hole under the restriction of the slide groove 27, thereby fixing or releasing the clamping jaws. When disassembling and assembling, the appropriate clamping jaws can be quickly replaced without long-term downtime adjustment or waiting for professional technicians to perform complex modifications. This greatly shortens production preparation time, enables the robot to quickly devote itself to new tasks, and improves overall production efficiency.

[0028] Considering that the clamping jaws are affected by gravity and the weight of the cargo when in use, the connecting column 32 may slide down, which may cause the clamping force to decrease and fall off after long-term use. Therefore, it is necessary to restrict the movement of the clamping jaws. Figures 1-3, a clamping plate 281 is fixedly connected to the clamping block 28, and one end of the clamping plate 281 extends out of the end of the clamping block 28. The extending length of the clamping plate 281 is the same as the depth of the fixing groove 282, ensuring that it can be completely clamped. A fixing groove 282 adapted to the clamping plate 281 is provided on the connecting column 32. When the connecting column 32 is inserted into the mounting hole, the fixing groove 282 has the same height as the clamping plate 281. Subsequently, with the sliding approach of the clamping block 28, the clamping plate 281 is driven to approach and insert into the fixing groove 282. Through the double fixation of the clamping block 28 and the clamping plate 281, the connecting column 32 can be firmly clamped, preventing the jaws from falling off due to insufficient clamping force during use, reducing the safety risk during use, improving the safety of the jaws during use, and reducing damage caused by dropping.

[0029] Considering that the clamping block 28 requires a power drive when approaching or moving away from the connecting column 32, adding an additional power source would involve complex power connection and disconnection issues during disassembly and assembly, increasing the overall usage cost and the load on the robotic arm. Refer to Figures 1-4 , the driving assembly 4 includes a rotating groove 41 provided on the support column 21. A rotating block 42 fixed to the worm 24 is rotatably installed in the rotating groove 41, and the rotating block 42 is used to drive the worm 24. The rotating block 42 is flush with the surface of the rotating groove 41, and a clamping groove 43 is provided on the rotating block 42 without exceeding the surface of the support column 21, ensuring that it will not be damaged by collision during the use of the robotic arm and reducing the risk of downtime. The clamping groove 43 is cross-shaped and its depth is slightly less than its thickness. The thickness of the insertion block 45 is greater than that of the clamping groove 43, ensuring sufficient size to drive its rotation and preventing damage during rotation due to too small a size. A rotating handle 44 is detachably installed in the rotating groove 41, and the rotating handle 44 is used to provide a force application point when rotating the insertion block 45. An insertion block 45 adapted to the clamping groove 43 is fixedly connected to the end of the rotating handle 44, and the insertion block 45 is used to drive the rotating block 42. When the position of the clamping block 28 needs to be adjusted, the insertion block 45 of the rotating handle 44 is aligned with the clamping groove 43 and inserted. Subsequently, the rotating handle 44 is rotated to drive the rotating block 42 to rotate on the worm 24, and the rotation of the worm 24 drives the sliding of the clamping block 28, thereby realizing the fixation and release of the clamping block 28 to the connecting column 32, enabling simple and rapid disassembly and assembly of the robotic arm jaws without the need for an additional power source. When replacing the jaws or performing other disassembly and assembly operations on the manipulator, there is no need to consider complex power connection and disconnection issues, and the mechanical components can be directly disassembled and installed, greatly simplifying the disassembly and assembly process. Reducing errors and delays that may be caused by complex operations. Reducing energy consumption reduces the equipment investment cost and the overall production cost.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, considering that the fixation of the connecting column 32 by the clamping block 28 and the clamping plate 281 may cause damage to it, resulting in a decrease in the clamping force after long-term use and a reduction in its service life, it is necessary to reduce the damage to the connecting column 32. Refer to Figures 1-3 , rubber pads 283 are fixedly connected to the clamping block 28, the clamping plate 281, and the fixing groove 282, and the thickness of the rubber pads 283 is not less than 0.5 cm to ensure that they are not easily broken due to the influence of force under clamping. When clamping the clamping block 28 and the clamping plate 281, the material of the rubber pads 283 can reduce the damage of the force to the connecting column 32 and increase the friction force on it to improve the fixing effect, thereby reducing the risk of damage to the connecting column 32 during use and improving the overall service life.
