Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic material detection, and specifically refers to a device for detecting the surface adhesion of magnetic materials. Background Art

[0002] In the production of magnetic materials, it is necessary to detect the surface adhesion of magnetic material products. The general detection method is to place the magnetic material product on a magnetic metal, and then use a certain tangential force to push the magnetic material product, so as to measure the surface adhesion of the magnetic material product. However, since the force required to push the magnetic material also depends on the surface roughness of the magnetic metal, the surface adhesion of the magnetic material measured by this detection method has certain limitations. At the same time, when taking and placing the magnetic material, it is necessary to overcome the magnetic attraction force, resulting in a cumbersome detection operation process, low efficiency, and a complex structure of the detection device.

[0003] In addition, when using the above traditional method to detect the adhesion of magnetic materials, a fixed-size thrust can only be applied each time, and it is impossible to detect multiple magnetic materials with different surface adhesions at the same time. Naturally, it is also impossible to classify the magnetic materials immediately according to the detection results, and subsequent manual marking and classification are required, which is time-consuming and laborious.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] As Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, it includes a horizontal rotation mechanism 100, a lifting and material taking mechanism 200, and a fixed base 300. The horizontal rotation mechanism 100 is arranged on the fixed base 300. The horizontal rotation mechanism 100 includes a magnetic adsorption centrifugal disc 101. The magnetic adsorption centrifugal disc 101 is rotationally connected to the fixed base 300. The lifting and material taking mechanism 200 includes a material taking disc 201. The material taking disc 201 is located above the magnetic adsorption centrifugal disc 101. The material taking disc 201 is used to take off magnetic materials from the magnetic adsorption centrifugal disc 101.

[0029] The upper surface of the magnetic adsorption centrifugal disc 101 is horizontal. A plurality of magnetic metal rings 104 are arranged on the upper surface of the magnetic adsorption centrifugal disc 101. The plurality of magnetic metal rings 104 are concentrically arranged. The surface average roughness of the magnetic metal ring 104 located on the outer side is greater than that of the magnetic metal ring 104 on the inner side.

[0030] In this embodiment, by setting the rotating magnetic adsorption centrifugal disc 101 and placing the magnetic material product on the magnetic adsorption centrifugal disc 101, when the magnetic adsorption centrifugal disc 101 rotates at a constant speed, the magnetic materials on the magnetic adsorption centrifugal disc 101 are subjected to centrifugal force. Since the rotational angular velocity of the magnetic materials is equal, the centrifugal force received by the magnetic materials changes linearly, that is, it is positively correlated with the rotational radius of the magnetic materials. And the magnetic materials can only maintain a fixed position on the magnetic adsorption centrifugal disc 101 when the maximum static friction force of their own is not less than the centrifugal force received, otherwise they will fly outwards; by utilizing the magnetism of the magnetic materials, magnetic metal rings 104 are arranged on the magnetic adsorption centrifugal disc 101 to change the maximum static friction force of the magnetic materials themselves, connecting the maximum static friction force with the magnetism, enabling magnetic materials with different magnetic distribution states to stay at different positions on the magnetic adsorption centrifugal disc 101, and thus the surface adhesion force of the magnetic materials can be expressed in the form of the magnetic distribution state, and further the detection of the surface adhesion force of the magnetic materials can be realized.

[0031] When the magnetic material is on the magnetic metal ring 104, an attractive force is generated between the magnetic material and the magnetic metal ring 104. Therefore, its maximum static friction force consists of the static friction force generated by its own gravity and the static friction force generated by the attractive force. To make the detection result more accurate, the magnetic metal ring 104 is set as a concentric nested structure. There are multiple layers of magnetic metal rings 104 arranged outward from the center of the magnetic attraction centrifugal disc 101, and the surface roughness of the magnetic metal rings 104 gradually increases from the center of the magnetic attraction centrifugal disc 101 outward.

[0032] Regarding the centripetal force required for the magnetic material, the centripetal force required for the magnetic material increases linearly from the center of the magnetic attraction centrifugal disc 101 outward. By adjusting the roughness of the magnetic metal ring 104, the centripetal force required for the magnetic material at each position of the magnetic metal ring 104 is slightly greater than the static friction force generated by the gravity of the magnetic material at that position, thereby generating a friction force difference that needs to be compensated. This friction force difference needs to be compensated by the static friction force generated by the attractive force; when the sum of the static friction force generated by the gravity of the magnetic material and the static friction force generated by the attractive force is not less than the centripetal force required for the magnetic material at that position, the magnetic material can remain stationary at that position, otherwise it will slide outward.

[0033] That is to say, when on the magnetic metal ring 104 near the center of the magnetic attraction centrifugal disc 101, the surface roughness of the magnetic metal ring 104 is small. When the attractive force of the magnetic material is large enough, the static friction force generated by the attractive force of the magnetic material can compensate for the above-mentioned friction force difference, enabling the magnetic material to remain stationary at that position; if the attractive force of the magnetic material is not large enough, it will slide outward to the magnetic metal ring 104 with a greater surface friction force. When on the magnetic metal ring 104 with a greater surface friction force, this part of the static friction force generated by the attractive force of the magnetic material will also increase accordingly until this part of the static friction force generated by the attractive force of the magnetic material can compensate for the above-mentioned friction force difference, and the magnetic material will stop sliding.

[0034] Therefore, during the rotation of the magnetic material on the magnetic attraction centrifugal disc 101, it stays at different radial positions according to its own attractive force, realizing the detection of the surface adhesion force of the magnetic material, and can detect multiple magnetic materials simultaneously, with high detection efficiency, simple and convenient operation steps, and clear and intuitive detection results; in addition, the magnetic materials with surface adhesion forces in the same interval are sorted out without manual sorting.

[0035] As Figure 6 shown, a central positioning block 106 is provided at the center position of the magnetic attraction centrifugal disc 101. A plurality of non-magnetic material rings 105 are arranged around the central positioning block 106. The plurality of magnetic metal rings 104 and the plurality of non-magnetic material rings 105 are concentrically arranged, and the plurality of magnetic metal rings 104 and the plurality of non-magnetic material rings 105 are alternately arranged.

[0036] In this embodiment, a non-magnetic material ring 105 is inserted between adjacent magnetic metal rings 104 with different roughnesses. The non-magnetic material ring 105 is made of a non-magnetic material and will not exert an attractive force on the magnetic material. Therefore, when the magnetic material is on the non-magnetic material ring 105, the source of the static friction it experiences is only its own gravity. For the non-magnetic material ring 105 near the central positioning block 106, which is the initial position for placing the magnetic material, when the magnetic adsorption centrifugal disc 101 rotates, the static friction force that the magnetic material experiences on the non-magnetic material ring 105 is too small to provide the centripetal force. Therefore, the magnetic material will slide outward onto the magnetic metal ring 104. A central positioning block 106 and a non-magnetic material ring 105 are provided at the center position of the magnetic adsorption centrifugal disc 101 to prevent the magnetic material from staying motionless at the center position of the magnetic adsorption centrifugal disc 101 and improve the effect of adhesion detection.

[0037] As Figure 5 and Figure 8 shown, on the side of the material taking disc 201 close to the magnetic adsorption centrifugal disc 101, there are an extrusion ring 205 and a magnetic material taking ring 207. The extrusion ring 205 and the magnetic material taking ring 207 are arranged alternately. The extrusion ring 205 is located directly above the magnetic metal ring 104, and the magnetic material taking ring 207 is located directly above the non-magnetic material ring 105.

[0038] In this embodiment, when the magnetic adsorption centrifugal disc 101 rotates, the centrifugal force generated moves the magnetic material to different positions, realizing the detection of the surface adhesion of the magnetic material. At the same time, since the magnetic adsorption centrifugal disc 101 is provided with a magnetic metal ring 104 with magnetism and a non-magnetic material ring 105 without magnetism, only the magnetic metal ring 104 can exert an attractive force on the magnetic material to increase the static friction force of the magnetic material. Therefore, when the magnetic adsorption centrifugal disc 101 stops rotating, the magnetic material is adsorbed on the magnetic metal ring 104. At this time, the material taking disc 201 is moved downward, and the extrusion ring 205 and the magnetic material taking ring 207 on the side of the material taking disc 201 close to the magnetic adsorption centrifugal disc 101 move towards the magnetic adsorption centrifugal disc 101.

[0039] When the pressing ring 205 moves to the position of the magnetic metal ring 104, the pressing ring 205 applies pressure to the magnetic material on the magnetic metal ring 104, and the generated tangential force pushes the magnetic material to slide on the magnetic metal ring 104. When the pressing ring 205 moves to the lowest position, the magnetic material is completely pushed from the magnetic metal ring 104 onto the non-magnetic material ring 105. The non-magnetic material ring 105 is made of non-magnetic material, so the non-magnetic material ring 105 will not exert an attractive force on the magnetic material. At this time, the magnetic material taking ring 207 is exactly above the non-magnetic material ring 105. The magnetic material taking ring 207 generates an attractive force on the magnetic material and adsorbs the magnetic material on the magnetic material taking ring 207. Subsequently, the material taking disc 201 is lifted upward, and all the magnetic materials can be removed from the magnetic adsorption centrifugal disc 101. At the same time, the distribution state of the magnetic materials on the material taking disc 201 is the same as that on the magnetic adsorption centrifugal disc 101, and the magnetic materials can be marked and classified with reference to the distribution state of the magnetic materials on the material taking disc 201.

[0040] As Figure 8 shown, the material taking disc 201 is provided with a pressing groove 206, the pressing ring 205 is slidably arranged in the pressing groove 206, a compression spring 210 is arranged in the pressing groove 206, both ends of the compression spring 210 are respectively connected to the pressing ring 205 and the pressing groove 206, and an inclined pressing surface 209 is arranged on the bottom surface of the pressing ring 205.

[0041] In this embodiment, when the material taking disc 201 moves downward, the pressing ring 205 first contacts the magnetic material. The inclined pressing surface 209 on the pressing ring 205 applies pressure to the magnetic material. The component force of this pressure in the horizontal direction pushes the magnetic material to slide on the magnetic metal ring 104, and the component force in the vertical direction acts on the compression spring 210, causing the compression spring 210 to compress and the pressing ring 205 to move into the pressing groove 206 at the same time. When the pressing ring 205 completely moves into the pressing groove 206, the magnetic material is pushed onto the non-magnetic material ring 105; subsequently, when the material taking disc 201 rises, the material taking disc 201 rebounds and pushes the pressing ring 205 back to its original position; the pressing ring 205 is set to be telescopic, and the inclined pressing surface 209 is used to push the magnetic material to avoid rigid extrusion of the magnetic material by the pressing ring 205, resulting in damage to the magnetic material.

[0042] As Figure 4 、 Figure 5 and Figure 6 shown, the horizontal rotation mechanism 100 includes a rotating main shaft 102 and a servo motor 103. The servo motor 103 is arranged on the fixed base 300, the rotating main shaft 102 is connected to the magnetic adsorption centrifugal disc 101, and the output shaft of the servo motor 103 is fixedly connected to the rotating main shaft 102.

[0043] In this embodiment, the servo motor 103 is arranged on the fixed base 300. When the servo motor 103 works, it drives the magnetic adsorption centrifugal disc 101 to rotate by rotating the main shaft 102. The rotation speed of the magnetic adsorption centrifugal disc 101 can be controlled by the servo motor 103. According to the actual parameters of the magnetic material to be detected, the rotation speed of the magnetic adsorption centrifugal disc 101 is adjusted, so that the magnetic material obtains an appropriate angular acceleration. Compared with ordinary motors, the servo motor 103 runs more smoothly, has a faster response speed, and higher control precision, and is suitable for detection equipment.

[0044] As Figure 6 shown, the lifting and material taking mechanism 200 includes a lifting screw 202, a worm and worm gear lift 203 and a lifting motor 204. The lifting screw 202 is rotatably arranged on the worm and worm gear lift 203. The lifting motor 204 is used to drive the action of the worm and worm gear lift 203. A lifting frame 208 is arranged on the material taking disc 201, and the lifting screw 202 is rotatably connected with the lifting frame 208.

[0045] In this embodiment, the lifting motor 204 drives the worm and worm gear lift 203 to drive the lifting screw 202 to rotate. When the lifting screw 202 rotates, the lifting frame 208 moves on the lifting screw 202. By changing the rotation direction of the lifting screw 202, the up and down movement of the lifting frame 208 is realized; after the adhesion detection of the magnetic material is completed, the worm and worm gear lift 203 drives the lifting screw 202 to drive the material taking disc 201 to move towards the magnetic adsorption centrifugal disc 101. After the material taking disc 201 adsorbs the magnetic material, the lifting screw 202 drives the material taking disc 201 to move away from the magnetic adsorption centrifugal disc 101. In order to more conveniently view the detection results and classify the magnetic materials, the material taking disc 201 can be removed from the lifting screw 202, and the material taking disc 201 can be reset after the detection result statistics is completed.

[0046] As Figure 4 、 Figure 5 and Figure 7 shown, an annular retaining ring 302 is arranged on the fixed base 300. The annular retaining ring 302 is located around the magnetic adsorption centrifugal disc 101. An annular material groove 303 is arranged on the annular retaining ring 302, and the opening position of the annular material groove 303 is close to the edge of the magnetic adsorption centrifugal disc 101.

[0047] In this embodiment, for some magnetic materials with very weak magnetism, the generated attraction is not enough to fix themselves on the magnetic adsorption centrifugal disc 101, and finally they slide to the edge of the magnetic adsorption centrifugal disc 101. An annular retaining ring 302 and an annular material groove 303 are arranged at the edge of the magnetic adsorption centrifugal disc 101. The annular retaining ring 302 plays a protective role to prevent the magnetic material from flying out of the magnetic adsorption centrifugal disc 101 and causing personal injury. At the same time, the annular material groove 303 stores these magnetic materials. The magnetic materials that slide to the edge of the magnetic adsorption centrifugal disc 101 fall into the annular material groove 303 and are scrapped or recycled as unqualified products.

[0048] As Figure 4 shown, a limiting bracket 301 is provided on the fixed base 300, and the rotating main shaft 102 is rotatably connected to the limiting bracket 301.

[0049] In this embodiment, when the servo motor 103 drives the rotating main shaft 102 to rotate, the rotating main shaft 102 rotates in the limiting bracket 301, and the limiting bracket 301 radially limits the rotating main shaft 102, avoiding tilting and deflection during the rotation of the rotating main shaft 102, ensuring that the magnetic adsorption centrifugal disc 101 can remain in the horizontal plane during rotation, and improving the stability of adhesion detection.
