Description

Technical Field

[0001] This invention relates to the field of magnetization technology, and in particular to a semi-automatic magnetization device for multi-pole magnetic rings. Background Technology

[0002] Magnets are widely used in industrial electronics. Their production process includes powder preparation, molding, curing, grinding, coating, and magnetization. Magnetization is the process of placing an object in a magnetic field created by a coil through which direct current flows, causing it to become magnetic. When magnetizing a cylindrical magnetic ring, the current procedure is as follows: First, manually activate the center push-out mechanism of the external magnetization coil to lower its support column. Then, place the cylindrical magnetic ring to be magnetized into the magnetization coil in a fixed orientation and press it down to the bottom using a soft rod. Next, start the magnetization power supply by foot to energize the coil. Then, activate the switch again to push the magnetic ring out from the bottom center of the coil. Finally, use a magnetic display film to cover the magnetic ring and check the magnetization process.

[0003] The utility model disclosed in CN214827005U is a feeding device for magnet processing, including a support platform 1, a support platform 2, and a support frame. Four support rods 1 are fixedly connected to the bottom outer wall of the support platform 1, and a support frame is fixedly connected to the side outer wall of the support platform 1. A circular through hole is opened on the horizontal plate of the support frame, and a screw is threaded into the circular through hole. A coil is fixedly connected to the bottom end of the screw. One end of the feeding trough is fixedly connected to the top outer wall of the support platform 1. Although it realizes automatic magnetization to replace manual operation, it cannot guarantee the magnetization quality requirements and is prone to producing defective products due to incomplete magnetization. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a semi-automatic magnetization device for multi-pole magnetic rings, which achieves automatic magnetization while ensuring magnetization quality and reducing the generation of defective products.

[0005] To achieve the above objectives, the present invention provides a semi-automatic magnetizing device for multi-pole magnetic rings, comprising a base plate, a feeding rail, a discharging rail, an infeed / discharge chute, and a magnetizing assembly. The feeding rail, the infeed / discharge chute, and the discharging rail are all mounted on the base plate via brackets. The discharging end of the feeding rail is inclined downwards and connects with the infeed / discharge chute, while the feeding end of the discharging rail is inclined upwards and connects with the infeed / discharge chute. The magnetizing assembly is connected to the infeed / discharge chute and has a magnetizing hole through it. A first push rod assembly and a second push rod assembly are provided on both sides of the magnetizing assembly for pushing the magnetic ring on the infeed / discharge chute into and out of the magnetizing hole sequentially. A third push rod assembly is provided on the side of the infeed / discharge chute for pushing the magnetic ring into the discharging rail.

[0006] In this invention, the magnetic ring to be magnetized is fed into the feed chute along the feeding rail. The first pusher assembly is activated to push the magnetic ring on the feed chute into the magnetization hole of the magnetization assembly for magnetization. The second pusher assembly is activated to push the magnetic ring in the magnetization hole back onto the feed chute. The third pusher assembly is then activated to push the magnetic ring from the feed chute into the discharge rail. The magnetized magnetic ring can be discharged and collected via the inclined discharge rail. During the entire magnetization process, only manual replenishment of the magnetic ring at the feeding rail is required. This allows the device to automatically magnetize each magnetic ring individually, avoiding the problem of defective products caused by manual improper insertion of the magnetic ring into the coil. It also reduces the skill requirements for operators and saves labor costs.

[0007] Optionally, it also includes a magnetic proximity switch and a baffle, the baffle being retractably mounted on the discharge rail, the magnetic proximity switch being mounted on the baffle, a logic controller and a control switch being mounted on the base plate, the magnetic proximity switch and the baffle being connected to the logic controller, the logic controller being also connected to the first push rod assembly, the second push rod assembly and the third push rod assembly, and the control switch being connected to the logic controller.

[0008] In this invention, a baffle is used to block the magnetized magnetic ring on the discharge rail. A magnetic proximity switch can detect whether the magnetic ring has magnetic force. When the magnetic ring has magnetic force, the magnetic proximity switch transmits a signal to the logic controller, which then controls the baffle to release the obstruction of the magnetic ring, allowing the magnetic ring to be smoothly output from the discharge rail. The magnetization status of each magnetic ring is automatically detected in real time, and unqualified magnetic rings are automatically intercepted and rejected, reducing the risk of defective products flowing out. The extension and retraction of the first push rod assembly, the second push rod assembly, and the third push rod assembly are all controlled by the logic controller, so that the magnetization of each magnetic ring is strictly controlled, avoiding the inconsistencies in the magnetization state caused by manual operation.

[0009] Optionally, the magnetization assembly includes a coil and a power junction box. The coil is mounted on the base plate via a bracket. The magnetization hole is opened in the center of the coil. The power junction box is electrically connected to the coil via a power cord. The power junction box is covered with a transparent cover and externally connected to a magnetization power supply. The magnetization power supply is electrically connected to the logic controller via a start signal line.

[0010] In this invention, the power junction box serves as the hub for the electrical connection between the magnetizing power supply and the coil, so as to better supply power to the coil. The transparent box cover is used to prevent the wiring terminals from being directly exposed to the environment and causing safety hazards. At the same time, it is convenient to observe the wiring status of the coil and the magnetizing power supply through the power junction box. The logic controller is electrically connected to the magnetizing power supply so as to control the magnetization of the magnetic ring by the coil in real time.

[0011] Optionally, the first push rod assembly, the second push rod assembly, and the third push rod assembly each include a push rod body and a mounting bracket. The mounting bracket is detachably mounted on the base plate, and the push rod body is fixedly mounted on the mounting bracket. The drive end of the push rod body of the first push rod assembly and the second push rod assembly is coaxially arranged with the magnetizing hole.

[0012] In this invention, the mounting bracket is used to provide mounting support for the push rod body, and the push rod bodies of the first push rod assembly and the second push rod assembly are designed to be coaxial with the magnetizing hole, so that the magnetic ring can be stably and accurately pushed into or out of the magnetizing hole.

[0013] Optionally, the mounting bracket includes a bracket body and at least one set of symmetrically arranged L-shaped legs. A first waist hole is provided on the base plate, a second waist hole is provided on the horizontal plate of the L-shaped legs, the first waist hole is perpendicular to the second waist hole, a vertical third waist hole is provided on the vertical plate of the L-shaped legs, and a fourth waist hole is provided on the bracket body corresponding to the third waist hole. Bolts are provided between the first waist hole and the second waist hole, and between the third waist hole and the fourth waist hole, and the protruding end of the bolt is threaded with a nut.

[0014] In this invention, by changing the connection position of the bolt on the first and second waist holes, the position of the L-shaped support leg on the plane of the base plate can be adjusted. By changing the connection position of the bolt on the third and fourth waist holes, the vertical position of the support body on the L-shaped support leg can be changed. This achieves the position adjustment of the push rod body installed on the support body in three-dimensional space, so as to achieve precise driving of the magnetic ring.

[0015] Optionally, the drive end of the push rod body of the third push rod assembly is connected to a C-shaped push plate, which is an open structure.

[0016] In this invention, the open-designed C-shaped push plate can better engage with the magnetic ring pushed back onto the feed / discharge slide, while providing lateral restraints as the magnetic ring moves from the feed / discharge slide into the discharge rail, allowing the magnetic ring to move better along the pushing direction of the third push rod assembly.

[0017] Optionally, the width of the feeding rail is designed to gradually decrease from top to bottom. An arc-shaped plate is provided at the top of the discharge end of the feeding rail. The upper end of the arc-shaped plate extends upward along the feeding rail, and the lower end of the arc-shaped plate extends downward to one side of the inlet and outlet slide. The lower part of the discharge end of the feeding rail extends downward to the other side of the inlet and outlet slide.

[0018] In this invention, the upper width of the feeding rail is set to be greater than the lower width, so that the magnetic ring can be better input from the upper feed end. When the magnetic ring is output from the lower discharge end of the feeding rail, its smaller size and closer to the length of the magnetic ring make the magnetic ring more accurately positioned when it falls into the feed and discharge slide, so that the first push rod assembly can better push the magnetic ring from the feed and discharge slide into the magnetization hole.

[0019] Optionally, the feeding / discharging chute is bonded to the corresponding bracket, the bracket is movably mounted on the base plate, the top of the feeding / discharging chute has an arc-shaped groove, the end face of the arc-shaped groove contacts and engages with the end face of the magnetizing hole and both are on the same arc surface, and the feeding / discharging chute is higher than the feeding end of the unloading rail.

[0020] In this invention, the height of the support at the bottom of the feeding and discharging slide is adjusted so that the arc-shaped groove of the feeding and discharging slide matches the position of the magnetizing hole, ensuring that the magnetic ring can achieve a precise and smooth transition when sliding axially between the feeding and discharging slide and the magnetizing hole, thus ensuring the smooth progress of the magnetizing process.

[0021] Optionally, the feed end of the discharge rail is an open design, and the discharge end of the discharge rail is used to connect to the collection box.

[0022] In this invention, the feed end of the discharge rail is set as an open structure, so that when the third push rod assembly pushes the magnetic ring on the feed and discharge slide into the discharge rail, the discharge rail can stably receive the magnetic ring. The magnetic rings that have passed inspection on the discharge rail can fall into the collection box for collection, ensuring the positive rate of the magnetic rings in the collection box.

[0023] Optionally, the feeding rail and the discharging rail are located on the same side of the infeed and discharging slide, and the third push rod assembly is located on the other side of the infeed and discharging slide.

[0024] In this invention, the feeding rail and the discharging rail are set on the same side of the inlet and outlet slides, making the spatial layout more compact. The magnetization and feeding of the magnetic rings and the collection of the discharging rings can be achieved on the same side, reducing the distance that workers need to move when feeding and collecting the magnetic rings.

[0025] Beneficial effects:

[0026] In this invention, the magnetic rings to be magnetized are fed into the inlet / outlet slide along an inclined feeding rail. The first pusher assembly is activated to push the magnetic rings on the inlet / outlet slide into the magnetization hole of the magnetization assembly for magnetization. The second pusher assembly is then activated to push the magnetic rings back from the magnetization hole onto the inlet / outlet slide. Finally, the third pusher assembly is activated to push the magnetic rings from the inlet / outlet slide into the outlet rail. The magnetized magnetic rings are then discharged via the inclined outlet rail for collection. Throughout the magnetization process, only manual replenishment of the magnetic rings at the feeding rail is required, enabling the device to automatically magnetize each ring individually. This avoids the problem of defective products caused by improper manual insertion of the magnetic rings into the coil, reduces the skill requirements for operators, and saves labor costs.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] See Figures 1 to 3According to an embodiment of the present invention, a semi-automatic magnetizing device for multi-pole magnetic rings includes a base plate 1, a feeding rail 21, a discharging rail 22, an inlet / outlet slide 23, and a magnetizing assembly 3. The feeding rail 21, the inlet / outlet slide 23, and the discharging rail 22 are all mounted on the base plate 1 by a bracket. The discharging end of the feeding rail 21 is inclined downward and docks with the inlet / outlet slide 23. The feeding end of the discharging rail 22 is inclined upward and docks with the inlet / outlet slide 23. The magnetizing assembly 3 is docked on the inlet / outlet slide 23 and has a magnetizing hole 311 through it. A first push rod assembly 51 and a second push rod assembly 52 are provided on both sides of the magnetizing assembly 3 for pushing the magnetic ring 4 on the inlet / outlet slide 23 into and out of the magnetizing hole 311. A third push rod assembly 53 is provided on the side of the inlet / outlet slide 23 for pushing the magnetic ring 4 into the discharging rail 22.

[0040] In this invention, the magnetic ring 4 to be magnetized is fed into the feed chute 23 along the feed rail 21. The first push rod assembly 51 is activated to push the magnetic ring 4 on the feed chute 23 into the magnetization hole 311 of the magnetization assembly 3 for magnetization. The second push rod assembly 52 is activated to push the magnetic ring 4 in the magnetization hole 311 back onto the feed chute 23. Then the third push rod assembly 53 is activated to push the magnetic ring 4 from the feed chute 23 into the discharge rail 22. The magnetized magnetic ring 4 can be discharged and collected through the inclined discharge rail 22. During the entire magnetization process, only manual replenishment of the magnetic ring 4 at the feed rail 21 is required to achieve automatic magnetization of the magnetic ring 4 one by one. This avoids the problem of defective products caused by manual improper insertion of the magnetic ring 4 into the coil 31, reduces the skill requirements of the operator, and saves labor costs.

[0041] See Figure 1 and Figure 2 In some embodiments of the present invention, a magnetic proximity switch 61 and a baffle 62 are also included. The baffle 62 is retractably disposed on the discharge rail 22. The magnetic proximity switch 61 is disposed on the baffle 62. A logic controller 71 and a control switch 72 are disposed on the base plate 1. The magnetic proximity switch 61 and the baffle 62 are both connected to the logic controller 71. The logic controller 71 is also connected to the first push rod assembly 51, the second push rod assembly 52 and the third push rod assembly 53. The control switch 72 is connected to the logic controller 71.

[0042] In this invention, baffle 62 is used to block the magnetized magnetic ring 4 on the discharge rail 22. Magnetic proximity switch 61 can detect whether the magnetic ring 4 has magnetic force. When the magnetic ring 4 has magnetic force, magnetic proximity switch 61 transmits a signal to logic controller 71, which then controls baffle 62 to release the obstruction of the magnetic ring 4, allowing the magnetic ring 4 to be smoothly output from the discharge rail 22. The magnetization status of each magnetic ring 4 is automatically detected in real time, and unqualified magnetic rings 4 are automatically intercepted and removed, reducing the risk of defective products flowing out. The extension and retraction of the first push rod assembly 51, the second push rod assembly 52, and the third push rod assembly 53 are all controlled by logic controller 71, so that the magnetization of each magnetic ring 4 is strictly controlled, avoiding the differences in magnetization status that may occur with manual operation.

[0043] See Figure 2 In some embodiments of the present invention, the magnetizing assembly 3 includes a coil 31 and a power junction box 32. The coil 31 is mounted on the base plate 1 by a bracket. The magnetizing hole 311 is opened in the center of the coil 31. The power junction box 32 is electrically connected to the coil 31 by a power line. The power junction box 32 is covered with a transparent cover and externally connected to a magnetizing power supply. The magnetizing power supply is electrically connected to the logic controller 71 by a start signal line.

[0044] In this invention, the power junction box 32 serves as the hub for the electrical connection between the magnetizing power supply and the coil 31, so as to better supply power to the coil 31. The transparent box cover is used to avoid the wiring terminals being directly exposed to the environment and causing safety hazards. At the same time, it is convenient to observe the wiring status of the coil 31 and the magnetizing power supply through the power junction box 32. The logic controller 71 is electrically connected to the magnetizing power supply so as to control the magnetization of the magnetic ring 4 by the coil 31 in real time.

[0045] See Figure 1 In some embodiments of the present invention, the first push rod assembly 51, the second push rod assembly 52 and the third push rod assembly 53 each include a push rod body 54 and a mounting bracket 55. The mounting bracket 55 is detachably mounted on the base plate 1, and the push rod body 54 is fixedly mounted on the mounting bracket 55. The driving end of the push rod body 54 of the first push rod assembly 51 and the second push rod assembly 52 is coaxially arranged with the magnetizing hole 311.

[0046] In this invention, the mounting bracket 55 is used to provide mounting support for the push rod body 54, and the push rod body 54 of the first push rod assembly 51 and the second push rod assembly 52 are coaxially designed with the magnetizing hole 311, so that the magnetic ring 4 can be stably and accurately pushed into or out of the magnetizing hole 311.

[0047] See Figure 2 and Figure 4In some embodiments of the present invention, the mounting bracket 55 includes a bracket body 551 and at least one set of symmetrically arranged L-shaped legs 552. A first waist hole 11 is provided on the base plate 1. A second waist hole 5521 is provided on the horizontal plate portion of the L-shaped legs 552. The first waist hole 11 is perpendicular to the second waist hole 5521. A vertical third waist hole 5522 is provided on the vertical plate portion of the L-shaped legs 552. A fourth waist hole 5511 is provided on the bracket body 551 corresponding to the third waist hole 5522. A bolt 56 is provided between the first waist hole 11 and the second waist hole 5521, and between the third waist hole 5522 and the fourth waist hole 5511. A nut is threadedly connected to the protruding end of the bolt 56.

[0048] In this invention, by changing the connection position of the bolt 56 on the first waist hole 11 and the second waist hole 5521, the position of the L-shaped support leg 552 on the plane of the base plate 1 can be adjusted. By changing the connection position of the bolt 56 on the third waist hole 5522 and the fourth waist hole 5511, the vertical position of the bracket body 551 on the L-shaped support leg 552 can be changed. In other words, the position adjustment of the push rod body 54 installed on the bracket body 551 in three-dimensional space is realized, so as to achieve precise driving of the magnetic ring 4.

[0049] See Figure 3 In some embodiments of the present invention, the drive end of the push rod body 54 of the third push rod assembly 53 is connected to a U-shaped push plate 531, which is an open structure.

[0050] In this invention, the open-designed C-shaped push plate 531 can better engage with the magnetic ring 4 pushed back onto the feed / discharge slide 23, while providing lateral restraints on both sides during the process of the magnetic ring 4 entering the discharge rail 22 from the feed / discharge slide 23, so that the magnetic ring 4 can move better along the pushing direction of the third push rod assembly 53.

[0051] See Figure 3 and Figure 5 In some embodiments of the present invention, the width of the feeding rail 21 is gradually reduced from top to bottom. An arc-shaped plate 211 is provided at the top of the discharge end of the feeding rail 21. The upper end of the arc-shaped plate 211 extends upward along the feeding rail 21, and the lower end of the arc-shaped plate 211 extends downward to one side of the inlet and outlet slide 23. The lower part of the discharge end of the feeding rail 21 extends downward to the other side of the inlet and outlet slide 23.

[0052] In this invention, the upper width of the feeding rail 21 is set to be greater than the lower width, so that the magnetic ring 4 can be better input from the upper feeding end. When the magnetic ring 4 is output from the lower discharge end of the feeding rail 21, its smaller size and closer to the length of the magnetic ring 4 make the magnetic ring 4 more accurately positioned when it falls into the feeding and discharging slide 23, so that the first push rod assembly 51 can better push the magnetic ring 4 from the feeding and discharging slide 23 into the magnetizing hole 311.

[0053] See Figure 3 In some embodiments of the present invention, the feeding / discharging chute 23 is bonded to the corresponding bracket, the bracket is movably mounted on the base plate 1, the top of the feeding / discharging chute 23 is provided with an arc-shaped groove 231, the end face of the arc-shaped groove 231 contacts and engages with the end face of the magnetizing hole 311 and both are on the same arc surface, and the feeding / discharging chute 23 is higher than the feeding end height of the unloading rail 21.

[0054] In this invention, the height of the support at the bottom of the feed / discharge slide 23 is adjusted so that the arc-shaped groove 231 of the feed / discharge slide 23 matches the position of the magnetizing hole 311, ensuring that the magnetic ring 4 can achieve a precise and smooth transition when sliding axially between the feed / discharge slide 23 and the magnetizing hole 311, thus ensuring the smooth progress of the magnetizing process.

[0055] See Figure 3 In some embodiments of the present invention, the feed end of the discharge rail 22 is designed to be open, and the discharge end of the discharge rail 22 is used to connect to the collection box.

[0056] In this invention, the feed end of the discharge rail 22 is set as an open structure, so that when the third push rod assembly 53 pushes the magnetic ring 4 on the feed slide 23 into the discharge rail 22, the discharge rail 22 can stably receive the magnetic ring 4, and the magnetic ring 4 that has passed inspection on the discharge rail 22 can fall into the collection box to complete the collection, ensuring the positive rate of the magnetic ring 4 in the collection box.

[0057] See Figure 5 In some embodiments of the present invention, the feeding rail 21 and the discharging rail 22 are disposed on the same side of the infeed and discharge slide 23, and the third push rod assembly 53 is disposed on the other side of the infeed and discharge slide 23.

[0058] In this invention, the feeding rail 21 and the discharging rail 22 are set on the same side of the inlet and outlet slide 23, which makes the spatial layout more compact, and the magnetization and feeding of the magnetic ring 4 can be realized on the same side, reducing the distance that workers need to move when feeding and collecting the magnetic ring 4.

[0059] In one embodiment of the present invention, the motion control logic of the logic controller 71 is as follows: Activate control switch 72, the push rod body 54 of the first push rod assembly 51 extends forward for 1.2 seconds—the push rod body 54 of the first push rod assembly 51 retracts for 1.3 seconds—the coil 31 is energized and magnetized for 1 second—the push rod body 54 of the second push rod assembly 52 extends forward for 1.2 seconds—the push rod body 54 of the second push rod assembly 52 retracts for 1.2 seconds—the push rod body 54 of the third push rod assembly 53 extends forward for 0.5 seconds—the push rod body 54 of the third push rod assembly 53 retracts for 0.5 seconds—the magnetic proximity switch 61 senses the magnetism of the magnetic ring 4—the baffle 62 opens for 2 seconds—the cycle continues. During the cycle, when the magnetic proximity switch 61 no longer senses the magnetism of the magnetic ring 4, the control switch 72 closes—the device stops operating—the push rod body 54 of the first push rod assembly 51 returns to the initial point—the push rod body 54 of the second push rod assembly 52 returns to the initial point—the push rod body 54 of the third push rod assembly 53 returns to the initial point.

[0060] When the present invention is in operation, the control switch 72 is activated, and the magnetic rings 4 to be magnetized are sequentially fed from the feed rail 21. The magnetic rings 4 fall naturally into the feed chute 23. At this time, the pusher body 54 of the first pusher assembly 51 extends forward, pushing the magnetic rings 4 from the feed chute 23 into the magnetization hole 311 of the coil 31. Then, the pusher body 54 of the first pusher assembly 51 retracts, and the coil 31 is energized to magnetize the magnetic rings 4. The pusher body 54 of the second pusher assembly 52 extends forward, pushing the magnetic rings 4 back from the magnetization hole 311 to the feed chute 23. Then, the pusher body 54 of the second pusher assembly 52 is controlled to extend forward. The device retracts and then controls the push rod body 54 of the third push rod assembly 53 to extend forward to push the magnetic ring 4 on the feed / discharge slide 23 to the discharge rail 22. The magnetic ring 4 rolls naturally from the discharge rail 22 to the baffle 62 and is blocked. At this time, the magnetic proximity switch 61 installed on the baffle 62 contacts the magnetic ring 4 and detects whether the magnetic ring 4 has magnetic force. When the magnetic ring 4 has magnetic force, the logic controller 71 controls the baffle 62 to open, and the magnetic ring 4 continues to fall from the discharge rail 22 to the collection box, thus completing the entire magnetization process. The operator only needs to replenish the magnetic ring 4 at the discharge rail 21 to realize the device to automatically magnetize the magnetic ring 4 one by one.

[0061] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
