Description

Technical Field

[0001] This utility model relates to the field of magnetic transfer technology, specifically to a magnetic adsorption type workpiece transfer mechanical structure. Background Technology

[0002] In industrial production, workpiece transfer is a crucial step. Traditional workpiece transfer methods, such as mechanical clamping and vacuum adsorption, have certain limitations. Mechanical clamping may damage the workpiece surface, especially for workpieces with high surface quality requirements. Vacuum adsorption, on the other hand, has high requirements for the material and surface flatness of the workpiece, and its application range is relatively narrow.

[0003] While existing magnetic adsorption transfer devices have solved some of the above problems, they lack auxiliary limiting functions. During the transfer process, the workpiece relies solely on magnetic adsorption. When the equipment starts, stops, turns, or is subjected to slight external vibrations, the workpiece is prone to horizontal displacement or even sliding along the adsorption surface. This displacement leads to a decrease in the accuracy of the workpiece placement, affecting the docking accuracy of subsequent processing or assembly processes and increasing the rework rate. Therefore, a magnetic adsorption workpiece transfer mechanical structure is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figure 1-4 As shown, this utility model provides a magnetic adsorption type workpiece transfer mechanical structure, including a base plate 1 and an electromagnet 3. The electromagnet 3 is installed at the center of the lower surface of the base plate 1. Multiple sets of through grooves 15 are opened on the surface of the base plate 1. A rotating block 14 is installed at the center of the upper surface of the base plate 1. A linkage component is installed at the upper end of the rotating block 14. A transmission component is provided at the upper end of the linkage component. A clamping component is provided at the lower end of the base plate 1. The clamping component is slidably disposed inside the through grooves 15.

[0020] Specifically, this utility model uses an electric telescopic rod 5 to drive the connecting plate 6, transmission rod 4, and four corner wheels 8 to move the slider 10, which in turn drives the clamping plate 13 to clamp the workpiece. Based on magnetic adsorption, mechanical clamping limit is added to effectively prevent the workpiece from shifting or sliding due to changes in equipment operating status or external vibration, improves the stability of transportation and the accuracy of workpiece placement, and ensures the smooth progress of subsequent processes.

[0021] The linkage assembly includes a transmission rod 4, four corner wheels 8, and a rotating shaft 9. The four corner wheels 8 are cross-shaped blocks and are rotatably mounted on the upper end of the rotating block 14. Multiple sets of transmission rods 4 are provided and correspond one-to-one with the through slots 15. One end of each set of transmission rods 4 is hinged to the four ends of the four corner wheels 8. The rotating shaft 9 is rotatably mounted inside the other end of the transmission rods 4. The transmission assembly drives the rotating shaft 9 to move, thereby driving one end of the transmission rod 4 to move inward, causing the other end to push the four corner wheels 8 to rotate. The rotation of the four corner wheels 8 can drive the multiple sets of transmission rods 4 to retract inward, thereby driving the clamping assembly to clamp the workpiece.

[0022] The transmission assembly includes an electric telescopic rod 5, a connecting plate 6, and a connecting block 7. Two sets of electric telescopic rods 5 are provided and placed on the upper end of the four corner wheels 8. One end of the connecting block 7 is connected to the output end of the electric telescopic rod 5, and one side of the connecting plate 6 is connected to the other end of the transmission rod 4. The upper end of the rotating shaft 9 is fixedly connected to the bottom of the connecting plate 6. By activating the electric telescopic rod 5, one end of the connecting block 7 can be pulled, causing the other end of the connecting block 7 to pull the connecting plate 6 to move. The movement of the connecting plate 6 can drive the linkage assembly and the clamping assembly to move.

[0023] The clamping assembly includes a limiting plate 11, a slider 10, a connecting rod 12, and a clamping plate 13. The slider 10 is slidably disposed inside the through groove 15. The limiting plate 11 is installed on the upper end of the slider 10 and is disposed on the upper surface of the base plate 1. The rotating shaft 9 is fixedly installed on the upper surface of the limiting plate 11. The upper end of the connecting rod 12 is connected to the bottom of the slider 10. The clamping plate 13 is disposed at the lower end of the connecting rod 12, and its upper surface is connected to the connecting rod 12. The transmission assembly drives the linkage assembly to rotate, thereby pulling the limiting plate 11 and the slider 10, moving them, and in turn driving the connecting rod 12 and the clamping plate 13 to move and clamp the workpiece.

[0024] Among them: the upper surface of the base plate 1 is fixedly installed with the outer shell 2, which covers the outside of the transmission component. The outer shell 2 is made of corrosion-resistant metal. The outer shell 2 can protect the components and extend their service life.

[0025] Among them, the connecting rod 12 and the clamping plate 13 are both made of polytetrafluoroethylene. Four sets of through grooves 15 are evenly opened along the circumference of the surface of the base plate 1. The through grooves 15 are long strips. The long strip-shaped through grooves 15 facilitate the movement of the connecting rod 12 and the clamping plate 13 to clamp the workpiece. By making the connecting rod 12 and the clamping plate 13 both made of polytetrafluoroethylene, the magnetic influence on the electromagnet 3 can be avoided when it is turned on.

[0026] Working principle: This utility model is a magnetic adsorption type workpiece transfer mechanical structure. First, the device is connected and installed at one end of the robotic arm. When transferring the workpiece, the electromagnet 3 is activated to adsorb the workpiece. Then, the electric telescopic rod 5 is activated to pull one end of the connecting block 7, causing the other end of the connecting block 7 to pull the connecting plate 6 to move. The movement of the connecting plate 6 can drive the limiting plate 11 to move accordingly. At the same time, it can drive the connected slider 10 to slide inside the through groove 15. The movement of the slider 10 can drive the connecting rod 12 and the clamping plate 13 to move accordingly. When the connecting plate 6 moves, it can push one end of the transmission rod 4 to move inward, thereby causing the other end to push the four corner wheels 8 to rotate. The rotation of the four corner wheels 8 can drive multiple sets of transmission rods 4 to retract inward, thereby driving multiple sets of connecting rods 12 to clamp and limit the workpiece.
