The manipulator is fixed at a required position with a fixed plate, and then the load-bearing arm 5 is connected to the fixed seat 3 through the load-bearing seat, and the reinforcing ribs 4 are used to strengthen the strength of the load-bearing seat, thereby improving the service life of the manipulator. The steering arm 6 is controlled to turn through an external controller, and the connecting arm 7 drives the splint 10 on one side of the connecting rod 8 to turn and move, thereby transferring and transporting rare earth materials.
[0024] The outer part of the telescopic rod 11 is provided with a clamping spring 14 , one end of which is fixedly connected to the inner surface of the clamping plate 10 . The clamping spring 14 can further clamp the rare earth material between the magnetic block 12 and the iron sheet 13 .
[0025] Among them, the surfaces of the magnetic block 12 and the iron sheet 13 are fixedly connected with an anti-slip pad 15, and the side shapes of the magnetic block 12 and the iron sheet 13 are both set in curves. The anti-slip pad 15 can increase the friction with the surface of the rare earth material, and the curve setting can increase the contact area between the magnetic block 12 and the iron sheet 13 and the rare earth respectively, so that the rare earth can be grasped more firmly.
[0026] Among them, the disassembly and assembly mechanism 9 includes a fixed block 91, which is fixedly connected to one end of the connecting arm 7, and one end of the connecting rod 8 is fixedly connected to an insertion block 92. A slot 93 is opened on one side of the fixed block 91, and the insertion block 92 is inserted into the inside of the slot 93.
[0027] The top and bottom of the insert block 92 are provided with slots 94 , the top and bottom of the fixing block 91 are provided with cavities, and a slide plate 95 is slidably connected to the inside of the cavity.
[0028] Among them, a clamping rod 96 is fixedly connected to the surface of the slide plate 95, one end of the clamping rod 96 passes through the inner wall of the fixed block 91 and is fixedly connected to the handle 97, the other end of the clamping rod 96 passes through the inner wall of the fixed block 91 and extends to the inside of the slot 93, and one end of the clamping rod 96 is clamped in the inside of the slot 94.
[0029] Among them, the outer sleeve of the clamping rod 96 is provided with a spring 98, and one end of the spring 98 is fixedly connected to one side of the slide plate 95. Since the clamping claw is in direct contact with the object and is constantly clamped and rubbed, it is more prone to damage. After long-term use, its clamping effect is not good. Therefore, the splint 10 and the internal structure can be quickly replaced through the disassembly and assembly mechanism 9. When replacing, the handle 97 is pulled outward, and the handle 97 drives one end of the clamping rod 96 to disengage from the slot 94, so that the plug block 92 can be taken out from the inside of the slot 93, and then a new splint 10 and other structures are replaced, and the new plug block 92 is inserted into the inside of the slot 93. The handle 97 is released, and the spring 98 pushes the slide plate 95 to move toward the inside of the slot 93 until one end of the clamping rod 96 is clamped into the inside of the slot 94, thereby completing the replacement of the splint 10 and its internal structure.
[0030] Working principle: When the gripper is used to transfer and transport rare earth materials, the manipulator is first fixed at the required position with a fixing plate, and then the load-bearing arm 5 is connected to the fixing seat 3 through the load-bearing seat, and the reinforcing rib 4 is used to strengthen the strength of the load-bearing seat to improve the service life of the manipulator. The steering arm 6 is controlled by an external controller to turn, and the connecting arm 7 drives the clamping plate 10 on one side of the connecting rod 8 to turn and move, thereby transferring and transporting the rare earth materials;
[0031] When the clamping clamp grasps the rare earth material, the movement of the clamping plate 10 is utilized to squeeze the rare earth material into the inner side of the clamping plate 10. Due to the mutual attraction between the magnetic block 12 and the iron sheet 13, the magnetic block 12 and the iron sheet 13 are brought close to each other and clamp the rare earth material, thereby achieving the purpose of clamping. Meanwhile, the clamping spring 14 outside the telescopic rod 11 can further clamp the rare earth material between the magnetic block 12 and the iron sheet 13. The arrangement of the magnetic block 12, the iron sheet 13 and the clamping spring 14 can be used for rare earth molded products of different models and sizes, especially some products that are easily deformed and damaged, thus achieving multi-purpose of one clamp and improving practicality. Moreover, the shape and appearance of the product will not be deformed or broken, thereby ensuring the quality of the rare earth when clamping.
[0032] The clamping jaws 95 are in direct contact with the object and are constantly clamped and rubbed, making them more susceptible to damage. After long-term use, the clamping effect is poor. Therefore, the disassembly and assembly mechanism 9 can be used to quickly replace the splint 10 and the internal structure. When replacing, the handle 97 is pulled outward, and the handle 97 drives one end of the clamping rod 96 to disengage from the clamping slot 94, so that the plug block 92 can be taken out from the inside of the slot 93, and then a new splint 10 and other structures are replaced. The new plug block 92 is inserted into the inside of the slot 93, and the handle 97 is released. The spring 98 pushes the slide plate 95 to move toward the inside of the slot 93 until one end of the clamping rod 96 is clamped into the inside of the slot 94, thereby completing the replacement of the splint 10 and its internal structure. The disassembly and assembly mechanism 9 can be used to facilitate the rapid replacement of the splint 10 and its internal structure, thereby ensuring the clamping quality inside the splint 10. The operation is simple, convenient and fast, and the splint 10 can be replaced separately, saving maintenance costs.
