Description

Technical Field

[0001] The utility model relates to the field of Halbach magnet groups, in particular to a magnetic suction claw mechanism for picking up, holding and releasing materials from a Halbach magnet group. Background Art

[0002] Halbach magnet group, also known as Halbach array, is a special magnet assembly structure, which is a nearly ideal structure in engineering. Halbach array significantly enhances the magnetic field on one side of the array and significantly weakens the magnetic field on the other side by arranging permanent magnets in different magnetization directions. Its goal is to use the least amount of magnets to generate the strongest magnetic field in the working area.

[0003] After the three strong magnets are arranged and integrated in the Halbach method, the attraction and repulsion between the polarities make it difficult to align the three magnets without collapsing. Manual grasping is laborious and inefficient, with a high failure rate. Utility Model Content

[0004] The utility model aims to provide a magnetic suction claw mechanism for holding and releasing a Halbach magnet group to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic claw mechanism for picking up, holding and releasing a Halbach magnet group, comprising a mounting frame, a first cylinder is fixedly mounted on one side of the front of the mounting frame, a second cylinder is fixedly mounted on the other side of the front of the mounting frame, linear sliders are mounted on the output ends of the first cylinder and the second cylinder, a third cylinder is fixedly mounted on the front of one of the linear sliders, a fourth cylinder is fixedly mounted on the front of the other linear slider, a magnetic claw shaft is connected to the bottom of the two linear sliders, a non-magnetic material stripping block is mounted on the output ends of the third cylinder and the fourth cylinder, a limiting clamp groove is provided at the bottom of the magnetic claw shaft, a Halbach magnet group is provided inside the limiting clamp groove, and an anti-magnet group is bonded to the top of the inner wall of the limiting clamp groove.

[0006] As a preferred technical solution of the utility model, the first cylinder and the second cylinder are symmetrically arranged, the third cylinder and the fourth cylinder are symmetrically arranged, one side of the first cylinder and one side of the second cylinder are both connected to a fixed base block, and the fixed base block is connected to the surface of the mounting frame.

[0007] As a preferred technical solution of the utility model, the top of the mounting frame is fixedly connected to a fixed top plate, a surface of the fixed top plate is provided with a plurality of mounting holes, a middle portion of the mounting frame is provided with a plurality of through holes, and a surface of the mounting frame is provided with fixing holes.

[0008] As a preferred technical solution of the utility model, the non-magnetic material stripping block is arranged corresponding to the magnetic claw shaft, and the non-magnetic material stripping block is sleeved on the outside of the magnetic claw shaft, the polarity of the anti-magnet group is opposite to the polarity of the Halbach magnet group, the bottom of the anti-magnet group is in contact with the top of the Halbach magnet group, and the anti-magnet group is used to adsorb the Halbach magnet group.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The first cylinder and the second cylinder extend and move the magnetic claw shaft downward, so that the magnetic claw shaft is close to the product. Since the limiting clamp groove at the bottom of the magnetic claw shaft is adhered with an anti-magnet group with the same polarity as the Halbach magnet group to be taken and the opposite polarity, the anti-magnet group can completely absorb the Halbach magnet group to complete the magnetic absorption of the product. When discharging, the first cylinder and the second cylinder attach the Halbach magnet group on the magnetic claw shaft to the workpiece, and start the third cylinder and the fourth cylinder to push the non-magnetic material removal pressure block coaxially configured with the magnetic claw shaft to press down the two sides of the Halbach magnet group.

The entire suction claw mechanism can ensure that the Halbach magnet is completely absorbed without collapse, thereby improving the efficiency of the Halbach magnet group in grasping and discharging, with a high success rate and easy use.
