Description

Technical Field

[0001] The utility model belongs to the technical field of manipulators, in particular to a multi-station displacement loading manipulator. Background Art

[0002] In modern industrial automated production, material transfer is a key link. With the expansion of production scale and the refinement of production technology, higher requirements are placed on the efficiency, precision and flexibility of transfer operations. Multi-station transfer robots have emerged. They can accurately and quickly transfer workpieces between multiple stations, greatly improving production efficiency.

[0003] However, the current multi-station displacement load-carrying manipulator has certain limitations in design. The traditional design method requires each station to be equipped with a cylinder or drive motor, and each station is equipped with an independent power source, which increases the hardware cost of the equipment; the independent power source of each station requires a separate control line and control system, which makes the control system of the entire manipulator complicated, increases the workload of programming and debugging, and the coordination and synchronization between different power sources also becomes a challenge, which is prone to control errors or uncoordinated movements, affecting the accuracy and stability of the transfer; the numerous cylinders and drive motors occupy a large space, making the structure of the multi-station displacement load-carrying manipulator bloated. In some environments with limited production space, this will limit the layout and optimization of the production line, and may even require a large installation space to be reserved specifically for the manipulator, reducing the space utilization rate of the production workshop. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a multi-station displacement load-carrying robot, which effectively solves the problem that each workstation of the existing multi-station displacement load-carrying robot needs to be separately configured with a power source, which not only increases the cost, but also increases the difficulty of controlling the coordination and synchronization between different power sources, and reduces the space utilization rate of the production workshop.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a multi-displacement load-carrying manipulator, including a support frame, the support frame is U-shaped, a cylinder is fixed on the top of the support frame, the movable end of the bottom of the cylinder is fixedly connected to a horizontal support top plate, a horizontal support cross bar is fixed to the bottom of the support frame, and a number of paired moving blocks are slidably provided on the support cross bar, a splint is fixedly installed on the bottom of the moving block, a top block is fixed on the top of the moving block, a connecting plate is slidably provided on the bottom of the support top plate, connecting rods are hinged on the connecting plate and the top block, and the connecting rods are symmetrically arranged.

[0006] Preferably, a plurality of bottom blocks arranged in pairs are fixed to the bottom of the supporting top plate, a threaded rod is rotatably provided on the bottom block, an end block is fixed to one end of the threaded rod, and the connecting plate and the threaded rod are threadedly connected.

[0007] Preferably, a mounting plate is fixed on the top of the support frame, and a mounting hole is provided on the mounting plate.

[0008] Preferably, vertical limiting side plates are fixed to the sides of the support frame, and the support top plate passes through the limiting side plates and slides relatively thereto.

[0009] Preferably, an anti-slip layer is provided on the side surface of the splint.

[0010] Preferably, the supporting cross bar is a square tube.

[0011] The utility model adopts the above structure to achieve the following beneficial effects:

[0012] 1. This multi-station transfer robot abandons the traditional mode of configuring a cylinder or drive motor for each station, and adopts an innovative centralized drive and transmission mechanism. It can complete the synchronous control of multiple groups of fixtures through a group of cylinders. This method greatly reduces the number of power sources required, thereby reducing hardware procurement costs, reducing the need for complex control circuits and control systems, simplifying programming and debugging, improving economic benefits, and enhancing the accuracy and stability of the transfer robot during multi-station operation.

[0013] 2. Due to the reduction of a large number of independent cylinders and drive motors, the overall structure of the multi-position load-carrying robot is more compact, which saves valuable space in the production workshop, makes the layout of the production line more flexible and optimized, and improves the space utilization of the production workshop.

The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, the utility model proposes a multi-displacement load-carrying manipulator, including a support frame 1, the support frame 1 is U-shaped, a cylinder 3 is fixed on the top of the support frame 1, and the movable end at the bottom of the cylinder 3 is fixedly connected to the horizontal support top plate 2, and a horizontal support cross bar 4 is fixed to the bottom of the support frame 1. A number of moving blocks 5 arranged in pairs are slidingly provided on the support cross bar 4. The support cross bar 4 is a square tube to ensure the stability of the moving block 5. A splint 15 is fixedly installed on the bottom of the moving block 5, and an anti-slip layer 16 is provided on the side of the splint 15 to increase friction and ensure the stability of clamping. A top block 7 is fixed on the top of the moving block 5, and a connecting plate 6 is slidingly provided at the bottom of the support top plate 2. Connecting rods 8 are hinged on the connecting plate 6 and the top block 7. The connecting rods 8 are symmetrically arranged to increase stability.

[0022] like Figure 3 、 4 As shown, a number of bottom blocks 9 arranged in pairs are fixed to the bottom of the supporting top plate 2, and a threaded rod 10 is rotatably provided on the bottom block 9. An end block 11 is fixed to one end of the threaded rod 10. The connecting plate 6 and the threaded rod 10 are threadedly connected. The rotating end block 11 drives the threaded rod 10 to rotate, thereby driving the connecting plate 6 to move. The connecting plate 6 drives the moving block 5 and the splint 15 to move as a whole, thereby adjusting the position of the splint 15.

[0023] like Figure 1 、 2 As shown, a mounting plate 13 is fixed on the top of the support frame 1 , and a mounting hole 14 is provided on the mounting plate 13 , and the support frame 1 is mounted on a moving device for movement.

[0024] like Figure 1 、 2 As shown in Figures 3, a vertical limiting side plate 12 is fixed to the side of the support frame 1, and the supporting top plate 2 passes through the limiting side plate 12 and slides relatively, limiting the supporting top plate 2 to increase stability and support.

[0025] When in use, the supporting frame 1 is installed on the moving device as a whole through the mounting plate 13, so that the clamping plate 15 is aligned with the position of the workpiece, and the cylinder 3 is started. The cylinder 3 drives the supporting top plate 2 to rise, and the supporting top plate 2 drives the connecting plate 6 to rise, thereby driving the connecting rod 8 to rotate, and the connecting rod 8 drives the top block 7 and the moving block 5 to move closer to each other, and then drives the clamping plate 15 to move closer to each other to clamp the workpiece, completing the synchronous clamping of the workpieces at multiple stations. Under the drive of the moving device, the workpiece is moved to the next station and then returned to its original position. The above operation is repeated to complete the multi-station synchronous transfer operation;

[0026] The synchronous control of multiple sets of clamps can be completed through a set of cylinders 3, which greatly reduces the number of power sources required, thereby reducing costs, reducing the need for complex control circuits and control systems, and improving the accuracy and stability of the transfer robot during multi-station operations.
