Abstract
Description
Technical Field
[0001] This utility model relates to the field of electro-permanent magnet chuck technology, and in particular to an electro-permanent magnet chuck for a robotic arm charging and demagnetizing controller. Background Technology
[0002] In automated production lines in industrial manufacturing, especially when transferring metal workpieces or materials between large equipment, robotic arms are used for handling. To improve the safety of the handling process, electro-permanent magnetic chucks are installed at the contact points between the robotic arm and the workpiece / material to prevent detachment from the workpiece / material.
[0003] The connection end of the robot arm and the electro-permanent magnet chuck are mostly installed in the form of bolts. Therefore, when performing maintenance or adjustment and replacement, multiple bolts need to be disassembled and installed, which is too cumbersome and affects the disassembly and assembly efficiency.
[0004] An existing patent (publication number: CN214956250U) discloses an electro-permanent magnet chuck for a robotic arm charging and demagnetizing controller. First, the hand lever at the top of the claw is pressed, which causes the bottom of the claw to rotate, thereby releasing the ratchet. Then, the rotating wheel at one end of the bidirectional threaded rod is rotated, which in turn causes the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the threaded sleeve block to move horizontally. The threaded sleeve block causes two sets of U-shaped limiting plates to move horizontally, which in turn causes the slider to slide inside the groove.
[0005] To address the aforementioned issues, while existing patents have proposed solutions that enable rapid assembly and disassembly of the electro-permanent magnet chuck and robotic arm using components such as bidirectional threaded rods and threaded sleeves, these solutions still require manual operation of components such as rotating discs and chucks. This demonstrates a significant reliance on human assistance, hindering automation and resulting in excessive labor intensity. Summary of the Invention
[0006] The purpose of this utility model is to provide an electro-permanent magnet chuck for a robotic arm charging and demagnetizing controller, which can avoid the excessive cumbersome manual disassembly and assembly process that affects disassembly and assembly efficiency, thereby solving the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an electro-permanent magnet chuck for a robotic arm charging and demagnetizing controller, comprising an electro-permanent magnet chuck, a connecting plate fixed to the top of the electro-permanent magnet chuck, a connecting shell provided above the connecting plate, a connecting end inserted into the top of the connecting shell, and limit mechanisms provided on both sides of the interior of the connecting shell.
[0008] The limiting mechanism includes a through block that extends through one side of the inner wall of the connecting shell, and a limiting block is connected to one end of the through block. A permanent magnet rod is fixed to one end of the through block that extends into the inner wall of the connecting shell, and an iron core is provided at the end of the permanent magnet rod away from the through block. A coil is sleeved on the outside of the iron core, and limiting holes are opened on both sides of the outer wall of the connecting end corresponding to the positions of the limiting blocks.
[0009] Preferably, the limiting block and the connecting plate form a sliding structure, and the size of the limiting block and the size of the limiting hole are matched.
[0010] Preferably, a mounting plate is fixed to the top of the protruding block, and a first damping spring is installed on the outer wall of the mounting plate.
[0011] Preferably, a slider is fixed at the bottom of the protruding block, and a groove is provided at the top of the connecting plate corresponding to the position of the connecting end.
[0012] Preferably, a reinforcing mechanism is provided above the limiting block. The reinforcing mechanism includes a bonding plate. Two bonding plates are arranged on both sides of the connecting end inside the connecting shell. A second damping spring is embedded at the bottom end of the bonding plate. An insertion rod is fixed at the top end of the bonding plate. Insertion holes are provided on the inner walls of both axial directions of the connecting end.
[0013] Preferably, the reinforcement mechanism further includes a locking block, which is fixed to one side of the second damping spring at the bottom of the bonding plate. A slot is provided on one side of the mounting plate at the top of the through-block. A metal block is fixed to the top of the insertion rod, and an electromagnet is embedded at the top of the connecting shell corresponding to the position of the metal block.
[0014] Preferably, the insertion rod forms a sliding structure between the bonding plate and the insertion hole, and the bonding plate forms an elastic fit with the connecting plate through the second damping spring.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. By cooperating with the permanent magnet rod, iron core and coil, the through block is pushed to allow the limit block to enter the limit hole, thereby limiting and fixing the connection end. During disassembly, the through block is easily reset by the mounting plate and the first damping spring, so that the electro-permanent magnet chuck and the robotic arm connection end can be quickly assembled and disassembled, avoiding the cumbersome manual disassembly and assembly process that affects the efficiency of disassembly and assembly.
[0017] 2. By sliding the through block and the limiting block, the locking block is pushed and the bonding plate is raised. The connection between the electro-permanent magnet chuck and the connecting end is further stabilized by the cooperation of the insertion rod and the insertion hole. At the same time, the stability of the limiting mechanism is improved by the cooperation of the locking block and the slot to prevent shaking. The limiting mechanism and the reinforcement mechanism are reset by the cooperation of the metal block and the electromagnet and the elastic contraction of the first damping spring and the second damping spring, so that quick disassembly can be achieved.

[0025] 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.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 4An electro-permanent magnet chuck for a robotic arm charging / demagnetizing controller includes an electro-permanent magnet chuck 1. A connecting plate 2 is fixed to the top of the electro-permanent magnet chuck 1. A connecting shell 3 is disposed above the connecting plate 2. A connecting end 4 is inserted into the top of the connecting shell 3. Limiting mechanisms 5 are disposed on both sides inside the connecting shell 3. The limiting mechanism 5 includes a protruding block 501 that protrudes from one side of the inside of the connecting shell 3. One end of the protruding block 501 is connected to a limiting block 502. A permanent magnet rod 503 is fixed to the end of the protruding block 501 that penetrates into the inner wall of the connecting shell 3. The permanent magnet rod 503 is located away from the inner wall of the connecting shell 3. One end of the through block 501 is provided with an iron core 504, and a coil 505 is sleeved on the outside of the iron core 504. Limiting holes 506 are opened on both sides of the outer wall of the connecting end 4 corresponding to the positions of the limiting block 502. The limiting block 502 and the connecting plate 2 form a sliding structure. The size of the limiting block 502 and the size of the limiting hole 506 are matched. The top of the through block 501 is fixed with a mounting plate 6. A first damping spring 7 is installed on the outer wall of the mounting plate 6. The bottom of the through block 501 is fixed with a slider 8. The top of the connecting plate 2 is provided with a groove 9 corresponding to the position of the connecting end 4.
[0028] By adopting the above technical solution, the connecting end 4 first slides along the slide groove 9 on the connecting plate 2 and enters the connecting shell 3. Then, the coil 505 is energized to generate magnetism in the iron core 504, thereby pushing the like permanent magnet rod 503 to slide. The through block 501 slides stably along the connecting plate 2 via the slider 8 to avoid deviation, thereby allowing the limiting block 502 to pass through the limiting hole 506 to limit the position. This allows the electro-permanent magnet chuck 1 and the robotic arm connecting end 4 to be quickly assembled, avoiding the troublesome and cumbersome manual twisting. When disassembly is required, the elastic contraction of the first damping spring 7 fixed by the mounting plate 6 is disconnected from the coil 505, and the resetting and disassembly can be performed.
[0029] Specifically, such as Figures 1 to 4 As shown, a reinforcing mechanism 10 is provided above the limiting block 502. The reinforcing mechanism 10 includes two bonding plates 1001, which are disposed on both sides of the connecting end 4 inside the connecting shell 3. A second damping spring 1002 is embedded at the bottom end of the bonding plate 1001, and an insertion rod 1003 is fixed at the top end of the bonding plate 1001. Insertion holes 1004 are provided on the inner walls of both axial directions of the connecting end 4. The reinforcing mechanism 10 also includes a locking block 1005, which is fixed to the bonding plate 1002. A slot 1006 is provided on one side of the second damping spring 1002 at the bottom of the 001 and on one side of the top mounting plate 6 of the through block 501. A metal block 1007 is fixed to the top of the insertion rod 1003. An electromagnet 1008 is embedded in the top of the connecting shell 3 at the position corresponding to the metal block 1007. The insertion rod 1003 forms a sliding structure between the bonding plate 1001 and the insertion hole 1004. The bonding plate 1001 forms an elastic fit with the connecting plate 2 through the second damping spring 1002.
[0030] By adopting the above technical solution, when the protruding block 501 slides, the limiting block 502 slides against the locking block 1005 until the protruding block 501 abuts against the locking block 1005 and the bonding plate 1001 rises, allowing the insertion rod 1003 to pass through the insertion hole 1004 through the connecting end 4 and insert into the connecting shell 3, thereby improving the stability of the connection between the electro-permanent magnet chuck 1 and the connecting end 4. At the same time, the locking block 1005 falls into the slot 1006 for locking, improving the stability of the limiting block 502. When disassembly or assembly is required, the coil 505 is closed, the electromagnet 1008 is activated to magnetically attract the metal block 1007, and the insertion rod 1003 is lifted, thereby separating the card block 1005 and the card slot 1006, making it easier for the through block 501 to reset. Then the electromagnet 1008 is disconnected and the second damping spring 1002 retracts to reset the bonding plate 1001, and the insertion rod 1003 passes through the insertion hole 1004, thereby facilitating the quick disassembly and assembly of the electro-permanent magnet chuck 1 and the connecting end 4.
[0031] Working principle: First, the connecting end 4 of the robotic arm inserts into the connecting shell 3 and is limited by contact with the connecting plate 2 via the sliding groove 9. Then, the coil 505 is energized, causing the iron core 504 to generate magnetic force, repelling the permanent magnet rod 503 with the same magnetism. This allows the protruding block 501 to push the limiting block 502 into the limiting hole 506, initially limiting the connecting end 4 so that the robotic arm and the electro-permanent magnet chuck 1 can be quickly assembled. The sliding block 8 allows the protruding block 501 to slide stably along the connecting plate 2. When the limiting block 502 enters the limiting hole 506, the locking block 1005 is lifted, thereby raising the bonding plate 1001. Under the elastic contraction of the second damping spring 1002, the locking block... 1005 and slot 1006 engage stably, while insertion rod 1003 passes through insertion hole 1004 through connection end 4 and inserts into connection shell 3 to further improve the connection stability between electro-permanent magnet chuck 1 and robotic arm connection end 4. When disassembling, coil 505 is disconnected, electromagnet 1008 and metal block 1007 are attracted, and second damping spring 1002 extends to separate block 1005 and slot 1006. Through block 501 is reset by the cooperation of mounting plate 6 and first damping spring 7. Then electromagnet 1008 is disconnected to reset insertion rod 1003, thereby separating electro-permanent magnet chuck 1 and robotic arm connection end 4.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
