Description

Technical Field

[0001] The present invention relates to the technical field of magnetic material processing, and more specifically to a magnetic material magnetizing device. Background Art

[0002] Magnetic materials play a vital role in modern industry and technology. From motors and speakers in household appliances, to sensors and storage devices in cars, to MRI equipment in the medical field, magnetic materials are used everywhere. However, the performance of magnetic materials depends largely on their magnetization state. Therefore, the magnetization technology of magnetic materials has become an important research field.

[0003] Traditional magnetic material magnetization methods often use manual operations, which is inefficient and difficult to ensure magnetization quality. With the continuous development of automation technology, magnetic material magnetization equipment has gradually achieved automation and intelligence. However, existing magnetization equipment still has some problems in magnetization efficiency, magnetization quality, and equipment stability and reliability.

[0004] First, the existing magnetizing equipment often lacks effective clamping and fixing of magnetic materials during the magnetizing process, which makes the magnetic materials easily shifted or dropped during the magnetizing process, thus affecting the magnetizing quality. Secondly, the existing magnetizing equipment lacks pretreatment of magnetic materials before magnetizing, such as cleaning and preheating, etc. These pretreatment steps are crucial to improving the magnetizing effect. In addition, the existing magnetizing equipment lacks effective testing and screening of magnetic materials after magnetizing, and is unable to promptly remove defective products with incomplete magnetization, thus affecting the quality and performance of the final product.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a magnetic material magnetization device. Summary of the invention

[0006] The object of the present invention is to provide a magnetic material magnetizing device to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A magnetic material magnetizing device comprises a magnetizing table, a conveyor belt assembly, a trigger assembly and a collection box, wherein a magnetizing cover is fixedly mounted on the upper end of the magnetizing table, a magnetizing head is mounted above the magnetizing cover at a position corresponding to the magnetizing cover, the conveyor belt assembly is mounted through a bracket and passes through the inner side and the upper part of the magnetizing cover, a plurality of evenly distributed clamping assemblies are mounted on the conveyor belt assembly, the clamping assemblies are used to clamp and fix the magnetic material to be magnetized, the trigger assembly is fixedly mounted on the upper end of the magnetizing table and is located behind the magnetizing cover, and the collection box is fixedly mounted behind the magnetizing table.

[0009] As a further improvement of the present invention, a feeding hole and a recovery hole are respectively provided at the upper end of the magnetizing table, the feeding hole is located in front of the magnetizing cover, and the recovery hole is located below the trigger assembly. A feeding hole is provided in front of the magnetizing table, and the feeding hole, the feeding hole and the recovery hole are all connected. The feeding hole is used to put the magnetic material to be magnetized into it, and the clamping assembly is used to adsorb the magnetic material, so that it rises from the feeding hole, is clamped and then sent to the magnetizing cover for magnetization. The magnetization quality is detected when passing through the trigger assembly, and the incompletely magnetized defective products will fall from the recovery hole and return to the feeding hole to wait for secondary magnetization.

[0010] As a further improvement of the present invention, the clamping assembly includes a U-shaped clamping block, a clamping groove is opened at one end of the U-shaped clamping block away from the conveyor belt assembly, and a test plate is fixedly connected to the inner walls on both sides of the clamping groove. A signal receiver and an electromagnet are installed on the U-shaped clamping block, and the signal receiver and the electromagnet are electrically connected. The test board is used to clamp the magnetic material, and the electromagnet can use the magnetic field to adsorb the magnetic material at the feeding hole, so that it rises to the U-shaped clamping block and is clamped, and the signal receiver is used to cooperate with the trigger assembly to realize signal reception.

[0011] As a further improvement of the present invention, an elastic airbag cushion is fixedly connected to the bottom wall of the clamping groove, and a plurality of evenly distributed blowing holes are provided on the inner walls on both sides of the clamping groove, and the elastic airbag cushion is connected to the blowing holes. When the magnetic material is adsorbed into the clamping groove, the elastic airbag cushion can, on the one hand, play a buffering and protective role for the magnetic material to avoid deformation or damage due to impact; on the other hand, after being squeezed by the magnetic material, the gas can be released through the blowing holes to clean the surface of the magnetic material, thereby reducing the influence of dust or impurities on the magnetization of the magnetic material.

[0012] As a further improvement of the present invention, an electric heating element is installed in the elastic airbag cushion, which is used to heat the gas in the elastic airbag cushion and then release the heated gas through the blowing holes. While cleaning its surface, it can be fully preheated. The heating treatment can improve the orderliness of the arrangement of its magnetic domains and may reduce hysteresis losses, thereby improving the magnetization effect.

[0013] As a further improvement of the present invention, the test plate includes a mounting plate, a friction plate and a guide strip. The mounting plate is fixedly connected to the upper end of the guide strip, and the mounting plate is located on the inner wall of the clamping groove. The friction plate is detachably connected to the outer side of the mounting plate. The mounting plate serves to fix the friction plate and the guide strip. The friction plate is used to clamp and test the magnetic material. The guide strip is used to guide the magnetic material to rise from the feeding hole into the clamping groove. A slight error is allowed and then corrected to allow it to enter smoothly.

[0014] As a further improvement of the present invention, the surface of the guide strip is smooth and is an arc surface extending inward, and the surface of the friction plate is rough.

[0015] As a further improvement of the present invention, a magnetic shielding groove is opened on the inner side of the U-shaped clamping block, a magnetic shielding sleeve is fixedly connected in the magnetic shielding groove, a test piece is slidably installed in the magnetic shielding sleeve, an arc surface extrusion block is fixedly connected to the upper end of the test piece, and the arc surface extrusion block is located on the upper side of the U-shaped clamping block. Under normal conditions, the magnetic shielding sleeve can magnetically shield the test piece to prevent it from being magnetized synchronously in the magnetizing cover, thereby affecting subsequent test results. When passing through the trigger assembly, the test piece is triggered to descend, so that it moves out of the magnetic shielding sleeve and out of the shielding range of the magnetic shielding sleeve, and then performs an adsorption test on the magnetized magnetic material.

[0016] As a further improvement of the present invention, the test piece includes an extension rod, an adsorbed plate and a compression spring. The adsorbed plate is slidably installed on the inner side of the magnetic shielding sleeve. The extension rod is fixedly connected between the arc extrusion block and the adsorbed plate. A through hole matching the extension rod is provided at the upper end of the U-shaped clamping block. The compression spring is fixedly connected between the adsorbed plate and the bottom wall of the magnetic shielding slot. The extension rod has the effect of extending and pushing the adsorbed plate to descend. The adsorbed plate is used as the main body for adsorption test with the magnetized magnetic material. The compression spring is used to assist in resetting the test piece as a whole after the test is completed.

[0017] As a further improvement of the present invention, the trigger assembly includes a positioning frame, an arc-surface extrusion column and a signal transmitter. The arc-surface extrusion column is fixedly connected to the lower inner side of the positioning frame, and the signal transmitter is fixedly installed at one end of the positioning frame close to the magnetizing cover. The arc-surface extrusion column can squeeze the arc-surface extrusion block to trigger the descending action of the test piece, thereby testing the magnetized magnetic material. The signal transmitter cooperates with the signal receiver to send a signal to control the start of the electromagnet.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) The magnetic material magnetization equipment of the present invention realizes the automatic loading, clamping, magnetization, testing and screening of magnetic materials through the coordinated use of the conveyor belt assembly and the clamping assembly, thereby greatly improving the magnetization efficiency. At the same time, the conveyor belt assembly is set to an intermittent forward mode and can stop at a corresponding position for a certain period of time, which not only ensures a certain magnetization time, but also facilitates the accurate loading, testing and unloading of magnetic materials, further improving the magnetization efficiency. The clamping assembly can realize the automatic and continuous magnetization of magnetic materials, and can also separate adjacent magnetic materials from interfering with each other after magnetization.

[0020] (2) The clamping assembly of the present invention is designed with an elastic airbag cushion and an air blowing hole. When the magnetic material is adsorbed into the clamping groove, the elastic airbag cushion can play a buffering and protective role for the magnetic material to avoid deformation or damage caused by impact. At the same time, the gas is released through the air blowing hole to clean the surface of the magnetic material, thereby reducing the influence of dust or impurities on the magnetization of the magnetic material. In addition, an electric heating element is installed in the elastic airbag cushion to preheat the magnetic material, improve the orderliness of the arrangement of its magnetic domains, and possibly reduce hysteresis loss, thereby improving the magnetization effect.

[0021] (3) The trigger assembly and the clamping assembly of the present invention are used together to perform intelligent testing and screening of magnetic materials after magnetization. The test piece descends after being triggered and performs adsorption test on the magnetized magnetic material to judge the magnetization quality of the magnetic material. Incompletely magnetized defective products will fall from the recovery hole and return to the feeding hole to wait for secondary magnetization, thereby ensuring the quality and performance of the final product.

[0022] (4) The magnetic material magnetizing device of the present invention has high adaptability. The test plate in the clamping assembly includes a mounting plate, a friction plate, and a guide strip. The friction plate can be detachably connected to the outer side of the mounting plate, which is convenient for technicians to replace later. In the face of different magnetic materials and magnetizing requirements, friction plates with different roughness can be replaced to meet the requirements of clamping and testing. In addition, the magnetic shielding sleeve can be made of different materials to meet different shielding requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] An implementation of the present application is described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] See also Figure 1-8 A magnetic material magnetizing device includes a magnetizing table 1, a conveyor belt assembly 3, a trigger assembly 5 and a collection box 6. A magnetizing cover 2 is fixedly installed on the upper end of the magnetizing table 1, and a magnetizing head 7 is installed above the magnetizing cover 2 at a position corresponding to the magnetizing cover 2. The conveyor belt assembly 3 is installed through a bracket and passes through the inner side and the top of the magnetizing cover 2. A plurality of evenly distributed clamping assemblies 4 are installed on the conveyor belt assembly 3. The clamping assemblies 4 are used to clamp and fix the magnetic material to be magnetized. The trigger assembly 5 is fixedly installed on the upper end of the magnetizing table 1 and is located behind the magnetizing cover 2. The collection box 6 is fixedly installed behind the magnetizing table 1.

[0036] The conveyor belt assembly 3 and the magnetizing head 7 are both prior art, and their specific structures and principles are not described in detail here.

[0037] A feeding hole 102 and a recovery hole 103 are respectively provided at the upper end of the magnetizing table 1. The feeding hole 102 is located in front of the magnetizing cover 2, and the recovery hole 103 is located below the trigger component 5. A feeding hole 101 is provided in front of the magnetizing table 1. The feeding hole 101, the feeding hole 102 and the recovery hole 103 are all connected. The feeding hole 101 is used to put the magnetic material to be magnetized into it, and the clamping component 4 is used to adsorb the magnetic material, so that it rises from the feeding hole 102, is clamped and then sent to the magnetizing cover 2 for magnetization. The magnetization quality is detected when passing through the trigger component 5. The defective products with incomplete magnetization will fall from the recovery hole 103 and return to the feeding hole 102 to wait for secondary magnetization.

[0038] It is worth noting that the feeding hole 101 and the recovery hole 103 are both inclined downward in the direction close to the loading hole 102, and the corners of the feeding hole 101, the loading hole 102 and the recovery hole 103 are all arc-shaped, which facilitates the movement of the magnetic material inside.

[0039] The clamping assembly 4 includes a U-shaped clamping block 401, and a clamping groove is opened at one end of the U-shaped clamping block 401 away from the conveyor belt assembly 3. Test plates 405 are fixedly connected to the inner walls on both sides of the clamping groove. A signal receiver 404 and an electromagnet 4010 are installed on the U-shaped clamping block 401, and the signal receiver 404 and the electromagnet 4010 are electrically connected. The test board 405 is used to clamp the magnetic material, and the electromagnet 4010 can use the magnetic field to adsorb the magnetic material at the feeding hole 102, so that it rises to the U-shaped clamping block 401 and is clamped. The signal receiver 404 is used to cooperate with the trigger assembly 5 to realize signal reception.

[0040] An elastic airbag cushion 406 is fixedly connected to the bottom wall of the clamping groove, and a plurality of evenly distributed blowing holes 407 are provided on the inner walls on both sides of the clamping groove, and the elastic airbag cushion 406 is connected to the blowing holes 407. When the magnetic material is adsorbed into the clamping groove, the elastic airbag cushion 406 can, on the one hand, play a buffering and protective role for the magnetic material to avoid deformation or damage due to impact. On the other hand, after being squeezed by the magnetic material, the gas can be released through the blowing holes 407 to clean the surface of the magnetic material, thereby reducing the influence of dust or impurities on the magnetization of the magnetic material.

[0041] An electric heating element 409 is installed in the elastic airbag cushion 406. The electric heating element 409 is used to heat the gas in the elastic airbag cushion 406 and then release the heated gas through the blowing hole 407. While cleaning its surface, it can be fully preheated. The heating treatment can improve the orderliness of the arrangement of its magnetic domains and may reduce hysteresis loss, thereby improving the magnetization effect. The specific heating temperature is determined according to the type of magnetic material, but must be much lower than the Curie temperature of the magnetic material. The electric heating element 409 can be an electric heating plate, an electric heating tube, etc.

[0042] The test plate 405 includes a mounting plate 4051, a friction plate 4052 and a guide bar 4053. The mounting plate 4051 is fixedly connected to the upper end of the guide bar 4053, and the mounting plate 4051 is located on the inner wall of the clamping groove. The friction plate 4052 is detachably connected to the outer side of the mounting plate 4051. The mounting plate 4051 serves to fix the friction plate 4052 and the guide bar 4053. The friction plate 4052 is used to clamp and test the magnetic material. The guide bar 4053 is used to guide the magnetic material to rise from the feeding hole 102 into the clamping groove. A slight error is allowed and then corrected to allow it to enter smoothly.

[0043] The surface of the guide strip 4053 is smooth and is an arc extending inward, and the surface of the friction plate 4052 is rough. The detachable connection method can be bonding, snapping or other methods, which is convenient for technicians to replace it later. The friction plate 4052 is a wear material and needs to be replaced regularly to ensure the clamping and testing accuracy. In the face of different magnetic materials and magnetization requirements, it is necessary to replace the friction plate 4052 with different roughness to meet the clamping and testing requirements.

[0044] A magnetic shielding groove is opened on the inner side of the U-shaped clamping block 401, and a magnetic shielding sleeve 408 is fixedly connected in the magnetic shielding groove. A test piece 402 is slidably installed in the magnetic shielding sleeve 408, and an arc-surface extrusion block 403 is fixedly connected to the upper end of the test piece 402, and the arc-surface extrusion block 403 is located on the upper side of the U-shaped clamping block 401. Under normal conditions, the magnetic shielding sleeve 408 can magnetically shield the test piece 402 to prevent it from being magnetized synchronously in the magnetizing cover 2, thereby affecting subsequent test results. When passing through the trigger component 5, the descending action of the test piece 402 is triggered, so that it moves out of the magnetic shielding sleeve 408 and out of the shielding range of the magnetic shielding sleeve 408, and then performs adsorption test with the magnetized magnetic material.

[0045] The magnetic shielding sleeve 408 can be made of magnetic shielding materials that are not magnetic themselves, such as plastic, copper, aluminum alloy, etc. The specific material can be selected according to different shielding requirements.

[0046] The test piece 402 includes an extension rod 4021, an adsorbed plate 4022 and a compression spring 4023. The adsorbed plate 4022 is slidably installed on the inner side of the magnetic shielding sleeve 408. The extension rod 4021 is fixedly connected between the arc extrusion block 403 and the adsorbed plate 4022. A through hole matching the extension rod 4021 is provided at the upper end of the U-shaped clamping block 401. The compression spring 4023 is fixedly connected between the adsorbed plate 4022 and the bottom wall of the magnetic shielding slot. The extension rod 4021 has the effect of extending and pushing the adsorbed plate 4022 to descend. The adsorbed plate 4022 is used as the main body for adsorption test with the magnetized magnetic material. The compression spring 4023 is used to assist the test piece 402 to reset as a whole after the test is completed.

[0047] The adsorbed plate 4022 is made of a material that does not have magnetism itself but can be adsorbed by magnetic materials, such as iron. In subsequent tests, it can avoid its own influence and test the magnetization effect of the magnetic material well.

[0048] The trigger assembly 5 includes a positioning frame 501, an arc-surface extrusion column 502 and a signal transmitter 503. The arc-surface extrusion column 502 is fixedly connected to the lower inner side of the positioning frame 501. The signal transmitter 503 is fixedly installed at one end of the positioning frame 501 close to the magnetizing cover 2. The arc-surface extrusion column 502 can squeeze the arc-surface extrusion block 403 to trigger the descending action of the test piece 402 to test the magnetized magnetic material. The signal transmitter 503 cooperates with the signal receiver 404 to send a signal to control the start of the electromagnet 4010.

[0049] The signal transmitter 503 is located in the front and can send a signal to the signal receiver 404 before the test piece 402 is squeezed to trigger the descending action, thereby controlling the electromagnet 4010 to cut off the power and remove the magnetic field. Then the clamping assembly 4 continues to move backward as a whole until the test piece 402 is indirectly squeezed by the arc-surface squeezing column 502 to trigger the descending action to start the test.

[0050] The signal transmitter 503 and the signal receiver 404 may use infrared signals or laser signals.

[0051] It is worth noting that the clamping component 4 has its own power supply to power components such as the electromagnet 4010 and the signal receiver 404, and can be controlled by an integrated microcontroller. Under normal conditions, the controller controls the electromagnet 4010 to turn on to adsorb and clamp the magnetic material. When testing, the influence of the electromagnet 4010 needs to be removed. When passing through the trigger component 5, the signal receiver 404 will receive the signal of the signal transmitter 503. The controller can then control the electromagnet 4010 to delay closing, wait for the test piece 402 to be squeezed and dropped for testing, and then delay opening. The specific delay control can be achieved through a timer, and the corresponding time needs to be calculated based on the forward speed of the conveyor belt component 3. The specific circuit connection and control method are prior art and will not be repeated here.

[0052] In addition, the selection of electromagnet 4010 is also very important. It is necessary to avoid being disturbed by the magnetizing magnetic field as much as possible. Therefore, the magnetic field of electromagnet 4010 should be consistent with or close to the magnetizing magnetic field as much as possible, so that the adsorption and clamping of the magnetic material can be maintained when passing through the magnetizing magnetic field.

[0053] During magnetization, the magnetized magnetic material is firstly put into the magnetization table 1 through the feeding hole 101, and then the conveyor belt assembly 3 starts the circular conveying clamping assembly 4. The clamping assembly 4 adsorbs and clamps the magnetic material at the feeding hole 102, which can not only realize the automatic continuous magnetization of the magnetic material, but also separate the adjacent magnetic materials from interfering with each other after magnetization. After entering the clamping groove, the magnetic material squeezes the elastic airbag cushion 406, and the gas heated by the electric heating element 409 is released through the blowing hole 407, and then the surface of the magnetic material is heated and cleaned. The heating treatment can improve the orderliness of the arrangement of its magnetic domains and may reduce the hysteresis loss, thereby improving the magnetization effect, and cleaning The impurities on the surface of the magnetic material are removed to ensure that the magnetic field can smoothly penetrate the material during the magnetization process to improve the magnetization effect. As the conveyor belt assembly 3 runs, the clamping assembly 4 clamps the magnetic material and enters the magnetization cover 2. The magnetization head 7 in operation can magnetize the magnetic material. After the magnetization is completed, it moves to the trigger assembly 5 until the signal emitted by the signal transmitter 503 is received by the signal receiver 404 to prepare for the delayed closing of the electromagnet 4010. When the arc surface extrusion block 403 contacts the arc surface extrusion column 502 and is squeezed, the test piece 402 moves downward as a whole. At this time, the adsorbed plate 4022 leaves the shielding range of the magnetic shielding sleeve 408 and corresponds to the test plate 405. The electromagnet 4010 is synchronously closed and loses the magnetic field. After magnetization, the material has magnetism and can be adsorbed and fixed with the adsorbed plates 4022 on both sides without falling off. However, when the magnetic material is not fully magnetized, the magnetism of the magnetic material will be weak, and the adsorption force will be insufficient to support the magnetic material to be fixed by friction resistance, so it will fall to the recovery hole 103 below to be recovered and wait for secondary magnetization. It is worth noting that the roughness of the friction plate 4052 determines the size of the friction resistance, so it is necessary to test it before magnetization to ensure that the fully magnetized magnetic material is clamped in the air with the friction plate 4052 by magnetic force and friction resistance. Once the magnetic force is insufficient, it will fall off. When the magnetic material is fully magnetized and the magnetic force meets the requirements, it can rely on the friction plate 4052. The friction resistance is clamped in the air and continues to move backward. At this time, the electromagnet 4010 is turned on by the timer to re-adsorb and fix the magnetic material. After leaving the trigger component 5, the test piece 402 is reset and replaced by the electromagnet 4010 for adsorption until it moves above the collection box 6 and the electromagnet 4010 is turned off again. After losing the adsorption effect, the magnetic material falls into the collection box 6 and is collected as a finished product. It can be seen that the start and stop time of the electromagnet 4010 are fixed, and maintain a certain corresponding relationship with the forward speed of the conveyor belt component 3. Therefore, the control of the electromagnet 4010 can be fully achieved by relying on the timer. At this point, the entire process of loading, magnetizing, testing, screening and unloading of the magnetic material is completed.

[0054] It is worth noting that the conveyor belt assembly 3 is preferably set to an intermittent forward mode, which is more suitable. It can stop at the corresponding position for a certain period of time, such as the loading hole 102, the magnetizing head 7, the recovery hole 103, and above the collection box 6. This not only ensures a certain magnetization time, but also facilitates the accurate loading, testing and unloading of magnetic materials.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
