Description

A recessed magnetic block positioning and transport structure Technical Field

[0001] This invention relates to the field of automatic mounting technology for strong magnetic steel, and in particular to a recessed magnetic block positioning and handling structure. Background Technology

[0002] High-performance strong magnetic blocks have applications in various fields such as industrial automation, electronics, rail transportation, aerospace, medical and new energy.

[0003] Precise and rapid mounting of magnets, especially medium- and high-performance strong magnets, is a problem that the industry needs to solve. As shown in Figures 4 and 5, the mounting structure required is particularly challenging with the double-row magnets in Figure 4.

[0004] Currently, most magnetic blocks are manually applied and mounted using positioning molds, which is very slow. As shown in Figure 4, it takes about 1-2 hours to complete one set of 40 magnetic blocks from application of adhesive to complete mounting. The current method of mounting magnetic blocks is inefficient. Moreover, when the magnetic blocks are larger than 30mm×10mm, the magnetic energy product is greater than 45MGOe (about 358KJ / m³), the remanence Br is greater than 13T, and the Hcj is greater than 14KOe, the magnetic blocks are prone to breakage and may cause safety accidents.

[0005] Developing a recessed magnetic block positioning and handling structure to improve mounting efficiency and reduce safety accidents during the mounting process has become a technical challenge that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a recessed magnetic block positioning and transport structure to solve the problems listed in the background art.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a recessed magnetic block positioning and transporting structure, including a base and a strong magnetic steel block. The lower surface of the base is fixedly connected to the upper end of the magnetic block, and the magnetic block generates an attractive force that magnetically connects with the strong magnetic steel block. The base is slidably connected to a limiting unit, and the limiting unit is fitted onto the outer circumferential surface of the magnetic block.

[0008] Preferably, the base includes a base section and a guide section, and the base section and the guide section are fixedly connected by bolts.

[0009] Preferably, the four corners of the base section are provided with clearance grooves, and the base section is provided with threaded holes; the four corners of the guide section are provided with guide through holes, and threaded through holes are provided between adjacent guide through holes; the threaded holes and the threaded through holes are positioned correspondingly, and the bolt passes through the threaded through holes and is fixedly connected to the threaded holes.

[0010] Preferably, the lower end of the magnetic block has a cavity.

[0011] Preferably, the limiting unit includes a guide post and a stainless steel limiting block. The stainless steel limiting block has threaded mounting holes at its four corners and a through groove in its center, which is slidably connected to the outer surface of the magnetic block. One end of the guide post passes through the threaded through hole and is fixedly connected to the threaded mounting hole, while the other end of the guide post is fitted with a spring limiting screw. A pressure spring is fitted on the outer circumferential surface of the guide post, with one end of the pressure spring abutting against the guide section and the other end of the pressure spring abutting against the stainless steel limiting block.

[0012] Preferably, it also includes a substrate, wherein the strong magnetic steel block generates an attractive force under the magnetic block base and is magnetically connected to the substrate.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The present invention provides a recessed magnetic block positioning and handling structure, in which a magnetic block is fixed on a base, a guide post is connected to the magnetic block through an opening, a pressure spring is added to each guide post, and a stainless steel magnetic block limiting block is connected below the guide post. At the same time, the stainless steel magnetic block limiting device is sleeved on the outside of the magnetic block. When applied to the automated processing of magnetic steel, it can effectively solve the problem of attraction and repulsion between magnetic blocks caused by the magnetic steel itself when the magnetic block is larger than 30mm×10mm, magnetic energy product is greater than 45MGOe, remanence Br is greater than 13T, and Hcj is greater than 14KOe. This not only greatly improves work efficiency, but also solves the problem of fragility of the base and magnetic steel due to the large instantaneous attraction during manual placement.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] As shown in Figures 1-3, a recessed magnetic block positioning and transport structure is provided. The lower surface of the base 1 and the upper end of the magnetic block 4 must be flat and fit together to avoid gaps that could affect the connection stability. The magnetic block 4 generates an attractive force 10 to detachably magnetically connect to the strong magnetic steel block 7. The base 1 is slidably connected to a limiting unit, which is fitted onto the outer circumference of the magnetic block 4 to limit the offset of the magnetic block 4 during the magnetic connection process, ensuring precise docking between the magnetic block 4 and the strong magnetic steel block 7, while also mitigating the impact force during magnetic adsorption and extending the overall service life of the structure.

[0019] Specifically, the base 1 includes a base section and a guide section. The base section and the guide section are fixedly connected by high-strength bolts. The bolt type can be selected according to the load-bearing requirements of the base. When connecting, it is necessary to ensure that the bolts are tightened in place to prevent loosening during long-term use.

[0020] Specifically, the four corners of the base section are provided with clearance grooves, the size of which matches the movement of the guide post in the installation environment to avoid interference between the movement of the guide post and the base section; and the base section is provided with a number of evenly distributed threaded holes, the specifications of which are adapted to the connecting bolts. The four corners of the guide section are provided with corresponding guide through holes, and threaded through holes are provided between adjacent guide through holes. The position and specifications of the threaded through holes correspond one-to-one with the threaded holes on the base section.

[0021] The threaded hole and the threaded through hole are positioned correspondingly. After the bolt passes through the threaded through hole, it is threadedly fixed to the threaded hole. A flat washer can be added between the bolt head and the upper surface of the guide section to enhance the anti-loosening performance of the connection and prevent the bolt from loosening due to vibration.

[0022] Specifically, the lower end of the magnetic block 4 is provided with a cavity 8. The cavity 8 can reduce the overall weight of the magnetic block 4, reduce the load on the base 1, and further reduce the magnetic attraction force.

[0023] Specifically, the limiting unit includes a guide post 2 and a stainless steel limiting block 6. The stainless steel limiting block 6 is made of 304 stainless steel, which has good wear resistance and corrosion resistance. It has threaded mounting holes at its four corners that match the guide post 2. A through groove is formed in the middle of the stainless steel limiting block 6. The inner diameter of the through groove matches the outer surface size of the magnetic block 4. The through groove is slidably connected to the outer surface of the magnetic block 4, ensuring that the magnetic block 4 can slide smoothly up and down along the through groove, while also providing radial limiting. The guide post 2 is made of high-strength alloy material. One end of it passes through the threaded through hole on the guide section and is threadedly fixed to the threaded mounting hole on the stainless steel limiting block 6. After connection, the guide post 2... The guide post 2 is coaxial with the guide through hole and the threaded mounting hole; a spring limiting screw 5 is installed at the other end of the guide post 2. The spring limiting screw 5 is used to limit the extension and retraction stroke of the pressure spring 3 to prevent the pressure spring 3 from being over-compressed or stretched and damaged; a pressure spring 3 is fitted on the outer circumferential surface of the guide post 2. The pressure spring 3 is made of stainless steel and has good elastic recovery performance and fatigue resistance. One end of the pressure spring 3 is in close contact with the lower surface of the guide section, and the other end of the pressure spring 3 is in close contact with the upper surface of the stainless steel limiting block 6. During the adsorption and separation process of the magnetic block 4 and the strong magnetic steel block 7, the pressure spring 3 can play a buffering and restoring role to ensure the smooth operation of the structure.

[0024] Specifically, it also includes a substrate 9, wherein the strong magnetic steel block 7 generates a magnetic attraction 11 under the magnetic block base and is magnetically connected to the substrate 9.

[0025] Working principle: When the structure moves above the strong magnetic steel block 7, the stainless steel limiting block 6 places the strong magnetic steel block 7 inside. Then, the magnetic attraction block 4 fixed on the base 1 presses down onto the strong magnetic steel block 7, attracting it. Subsequently, the base 1, along with the magnetic attraction block 4 and the strong magnetic steel block 7, rises, while the stainless steel limiting block 6 remains stationary under the action of the guide post 2 and the pressure spring 3, until the base 1, along with the magnetic attraction block 4 and the strong magnetic steel block 7, rises to the safe height of the stainless steel limiting block 6. The base 1, carrying the magnetic block 4, the stainless steel limiting block 6, and the strong magnetic steel block 7, arrives at the magnetic bonding mold position. The base 1 presses down, and the bottom of the stainless steel limiting block 6 first contacts the positioning mold on the substrate 9. As the base 1 continues to press down, the strong magnetic steel block 7 moves down inside the stainless steel limiting block 6 until it is completely installed on the surface of the substrate 9. The base 1 moves up, and the magnetic block 4 disengages from the strong magnetic steel block 7. The process continues until the stainless steel limiting block 6 disengages from the surface of the substrate 9 and reaches the standby height, thus completing the automatic bonding of a strong magnetic steel block.

[0026] To ensure that the magnetic block 4 can smoothly detach from the strong magnetic block 7 after the strong magnetic block 7 is adsorbed onto the substrate 9, 40% of the contact area between the magnetic block 4 and the strong magnetic block 7 is hollowed out to form a cavity 8.

[0027] Example 1

[0028] This technology, when applied to automated magnet processing, effectively solves the problems of attractive and repulsive forces between magnet blocks when the magnet is larger than 30mm × 10mm, the magnetic energy product is greater than 45MGOe (approximately 358KJ / m³), the remanence Br is greater than 13T, and the Hcj is greater than 14KOe. It also solves the problem of breakage due to excessive instantaneous attraction between the base and the magnet during manual mounting.
