Description

Technical Field

[0001] This utility model relates to the technical field of magnetic core blank processing equipment, and more specifically, to a magnetic core blank turntable alternating magnetic pick-up and release device. Background Technology

[0002] In the production of magnetic materials, the automated handling of magnetic core blanks is a key step in improving production efficiency. Traditional magnetic pick-and-place devices mostly use electromagnets or pneumatic grippers, which suffer from high energy consumption, complex structures, and slow response speeds. Especially for rotary multi-station operations, existing devices struggle to achieve rapid alternating adsorption and release, and insufficient magnetic control precision can easily lead to blank detachment or positioning deviations. Furthermore, traditional mechanical grippers are prone to wear, resulting in high maintenance costs. Therefore, there is an urgent need for a rotary magnetic pick-and-place device with a simple structure, controllable magnetic force, and low energy consumption to meet the requirements for efficient and stable transfer of magnetic core blanks. Utility Model Content

The turntable body has four pickup and release claws evenly distributed on it, each claw including a magnet hole and a magnet assembly. The upper and lower ends of the magnet hole are respectively provided with an upper top plate and a lower iron plate, and the side wall of the magnet hole has a movable groove. The magnet assembly includes a rocker arm hinged to the movable groove, a magnet body connected to one end of the rocker arm, and a roller at the other end. The rocker arm drives the magnet body to attract or separate from the lower iron plate by swinging up and down. A limiting block is provided below the limiting plate for pressing down the roller at a set position to release the blank.

[0006] Preferably, the four pick-and-place claws correspond to four workstations A, B, C, and D, where A is the gripping workstation, C is the unloading workstation, B is the transfer workstation, and D is the idle workstation. The limiting block has a ring structure, with the starting end of the limiting block located in front of workstation C and having a gentle slope, and the end extending to workstation D with increasing thickness to form a vertical surface.

[0007] Preferably, the upper top plate has a notch on the side near the movable groove to allow the rocker arm to move.

[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] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4The present invention provides a magnetic core blank turntable alternating magnetic pick-up and release device, including a turntable body 1 and a limiting plate 2 for fixing the turntable body 1. A drive motor for driving the turntable body 1 to rotate is installed on the limiting plate 2, the position of the limiting plate 2 is fixed, and the drive motor controls the rotation of the turntable body 1.

[0021] Specifically, the turntable body 1 is provided with four pick-and-place claws, each including a magnet hole 11 and a magnet assembly 12 disposed in the magnet hole 11. The upper end of the magnet hole 11 is provided with an upper top plate 111, and the lower end of the magnet hole 11 is installed with a lower iron plate 112. The lower iron plate 112 is fixed to the lower end of the magnet hole 11 by bolts to seal the magnet hole 11. A movable groove 113 is provided on the side of the magnet hole 11 near the limiting plate 2, and a notch is provided on the side of the upper top plate 111 near the movable groove 113.

[0022] More specifically, the magnet assembly 12 includes a rocker arm 121, a magnet body 122, and a roller 123. The middle position of the rocker arm 121 is hinged to the movable groove 113. A bearing seat is provided in the movable groove 113, which is movably connected to the rocker arm 121, facilitating the rotation of the rocker arm 121 around the bearing seat and changing the height of both ends of the rocker arm 121. The movable groove 113 and the notch allow the rocker arm 121 to move freely. One end of the rocker arm 121 extends into the magnet hole 11, and a pull rod 1211 is provided at the end of the rocker arm 121 that is in the magnet hole 11. The lower end of 11 is sleeved with the center of the magnet body 122. The magnet body 122 is placed in the magnet hole 11 and is controlled to move up and down by the rocker arm 121. When the rocker arm 121 moves the magnet body 122 upward, the magnet body 122 separates from the lower iron plate 112. The lower iron plate 112 loses its magnetic force and cannot attract the magnetic core blank. Conversely, when the rocker arm 121 is not under force, the magnet body 122 attracts the lower iron plate 112 under its own weight. The lower iron plate 112 obtains magnetic force and attracts the magnetic core blank. The other end of the rocker arm 121 is movably connected to a roller 123.

[0023] It should be noted that the four pick-and-place claws correspond to four workstations, denoted as A, B, C, and D respectively. A is the gripping workstation, C is the unloading workstation, B is the adsorption and movement workstation, and D is the idle workstation. The pick-and-place claws move sequentially along A, B, C, and D. A limit block 21 is provided on the lower surface of the limiting plate 2. The limit block 21 has a ring structure and starts before the C workstation. The starting position of the limit block 21 near the C workstation is a gentle slope structure. The limit block 21 extends towards the D workstation and increases in thickness. The end of the limit block 21 is a vertical surface and ends before the A workstation. Thus, the magnet assembly 12 rotates with the turntable body 1, and the corresponding roller 123 moves along the lower surface of the limiting plate 2. When gripping the magnetic core blank, the pick-and-place claws move to the A workstation. There is no limit block 21 above the roller 123 to restrict it, and the magnet body 122 is adsorbed to the lower iron plate 112 under its own weight. The lower iron plate 112 attracts the magnetic core blank below, and the magnetic core blank is moved by the turntable body 1. After passing station B, the pick-and-place claw moves to station C. The roller 123 descends along the gentle slope structure to below the limit block 21. The end of the rocker arm 121 near the roller 123 is pressed down. Correspondingly, the end of the rocker arm 121 with the magnet body 122 is raised too high. The magnet body 122 separates from the lower iron plate 112, and the lower iron plate 112 loses its magnetic force. The magnetic core blank is placed on the belt and conveyed to the next process. The pick-and-place claw continues to move to station D. The limit block 21 always presses the end of the rocker arm 121 with the roller 123 downward, keeping the magnet body 122 without magnetic force, until the pick-and-place claw moves to station A. The roller 123 is no longer pressed by the limit block 21, and the magnet body 122 attracts the lower iron plate 112 under its own weight, performing a cycle of pick-and-place operation.

[0024] Working process: When the turntable body 1 is stationary, the four pick-and-place claws are located at stations A, B, C, and D respectively. The magnet body 122 at station A is attracted to the lower iron plate 112 due to its own weight. The lower iron plate 112 generates magnetic force to attract the blank. The drive motor starts, the turntable body 1 rotates, and the pick-and-place claw at station A moves to station B after attracting the blank. The magnetic force is maintained, and the blank moves with the turntable. When the pick-and-place claw reaches station C, the roller 123 contacts the slope of the limiting block 21 and gradually presses down the rocker arm 121, causing the magnet body 122 to move up and detach from the lower iron plate 112. The magnetic force disappears, and the blank falls onto the belt. When the pick-and-place claw passes through station D, the limiting block 21 continues to press the roller 123, keeping the magnet body 122 suspended. After returning to station A, the roller 123 detaches from the limiting block 21, and the magnet body 122 resets and attracts the blank, starting the next cycle.
