Description

Technical Field

[0001] This application relates to the technical field of magnetizing magnetic materials, and in particular to an integrated device for magnetizing and detecting the surface magnetism of magnetic materials. Background Technology

[0002] Since the 20th century, with the rapid development of electronic technology and materials science, the types and properties of magnetic materials have been continuously improved, leading to a growing demand for magnetization technology. In industrial production, magnetic materials are widely used in many fields such as motors, generators, sensors, and loudspeakers, prompting continuous improvement and innovation in magnetization technology to meet the magnetization requirements of different magnetic materials and devices.

[0003] Traditional automated magnetization equipment magnetizes each product individually. After magnetization, a certain percentage of products will be under-magnetized, resulting in performance differences compared to fully magnetized magnets and affecting product usability. Currently, under-magnetized magnets are manually inspected using a development process. However, prolonged manual inspection leads to visual fatigue and cannot guarantee the removal of 100% defective magnets. This consumes significant manpower, greatly increasing costs for businesses and reducing product magnetization quality. Summary of the Invention

[0004] To improve the magnetization quality of products, this application provides an integrated device for magnetizing magnetic materials and detecting surface magnetism.

[0005] This application provides an integrated device for magnetizing and detecting the surface magnetic properties of magnetic materials, which adopts the following technical solution: A magnetic material magnetization and surface magnetization detection integrated device includes a feeding mechanism, a magnetizer, a detection mechanism, and a control mechanism. The feeding mechanism is used to transport the product to the magnetizer for magnetization. The detection mechanism is used to detect the surface magnetization of the magnetized product. The control mechanism outputs qualified products and returns unqualified products to the magnetizer for remagnetization based on the detection results.

[0006] By adopting the above technical solution, the feeding mechanism conveys the product to the magnetizer for magnetization. After magnetization, the product is moved to the testing mechanism for surface magnetization testing. When the product is saturated (i.e., a qualified product), the control mechanism controls the output of qualified products. When the product is unsaturated (i.e., a unqualified product), the control mechanism controls the product to flow back to the magnetizer for remagnetization. Then, it continues to be tested by the testing mechanism. The qualified and unqualified products are then sorted repeatedly, and qualified products are output while unqualified products are remagnetized.

[0007] By automating the feeding, magnetization, and testing of products, outputting qualified products and remagnetizing unqualified products, the manpower and enterprise costs can be greatly reduced, while also improving the magnetization effect, efficiency, and quality of the products.

[0008] Optionally, the testing organization includes: Track 1 and Track 2 are connected to each other. The product magnetized by the magnetizer is transported on Track 1 and positioned against the connection between Track 1 and Track 2. The surface magnetic detection head is used to detect the surface magnetic properties of magnetized products. The misalignment component is used to move the product, which is abutting against the connection between track one and track two, to the magnetic detection head for detection and to make the product adhere to the control mechanism for positioning.

[0009] By adopting the above technical solution, the magnetizer transports the magnetized product to track one, where the product continues to move until it comes into contact with the connection between track one and track two for positioning. The misalignment component pushes the product to the surface magnetization detection head for detection, and the product is then attached to the control mechanism for positioning. After the detection is completed, the control mechanism controls the output of qualified products and the return of unqualified products for continued magnetization, thereby realizing automatic magnetization, detection and screening of products, improving the magnetization effect and efficiency, and the magnetization quality of the products.

[0010] Positioning is achieved by the product abutting against the connection between track one and track two. The misalignment component pushes only one product to the magnetization detection head for detection, and then repeats the process. This ensures that only one product is present during detection, making the detection more accurate, stable, and continuous, thus improving the magnetization effect and efficiency, as well as the magnetization quality of the product.

[0011] Meanwhile, the product is positioned by being abutted against and attracted to the control mechanism when it is moved to the magnetic detection head, which facilitates positioning during product testing. After the test is completed, the product's movement can be quickly controlled, further improving the magnetization effect and efficiency, as well as the magnetization quality of the product.

[0012] Optionally, the control mechanism includes: The qualified track, NG track, and return track are set at intervals on the machine body; A magnetic adsorption block is slidably set on the machine body. When the product moves to the magnetic detection head via the second track, the product is connected to the qualified track. The magnetic adsorption block is adsorbed on the product for positioning and pulls the product to any of the qualified track, NG track and return track according to the detection result. Thrust assembly one, thrust assembly two, and thrust assembly three are respectively set up to correspond to the qualified track, NG track, and return track; If the magnetic detection head detects that the product is qualified, the first thrust assembly will push the product onto the qualified track for transport. If the magnetic detection head detects that the product's surface magnetism is not saturated, the magnetic adsorption block will pull the product to the return track, and the third thrust assembly will push the product back to the magnetizer via the return track for remagnetization. If the magnetic detection head detects that the product is qualified after remagnetization, it enters the qualified track. If the magnetic detection head detects that the product is still unqualified after remagnetization, the magnetic adsorption block pulls the product to the NG track, and the thrust assembly two is activated to push the product to the NG track for conveying.

[0013] By adopting the above technical solution, when the misalignment component pushes the product to the magnetic detection head for testing, the product is positioned against and adsorbed on the magnetic adsorption block. The magnetic detection head detects the surface magnetism of the product. After the test is completed, according to the test results, if the product is qualified, the first thrust component is activated to push the product to the qualified track for output. If the product is unqualified, it is in an unsaturated state. The magnetic adsorption block pulls the product to the return track. The third thrust component is activated to push the product back through the return track to the magnetizer for remagnetization.

[0014] The product continues to be tested by the magnetic detection head. If the product is qualified, it will be output into the qualified track. If the product is still unqualified, it indicates that there is a problem with the quality of the product itself. In this case, the magnetic adsorption block pulls the product to the NG track, and the thrust component two pushes the product to the NG track for output. At the same time, the number of times the product is returned can be designed as needed. By outputting the product through the NG track after repeated magnetization, the number of products that cannot meet the magnetization requirements due to their own quality is reduced. This reduces the risk of such products occupying the device for a long time and reducing the magnetization efficiency, thereby further improving the magnetization effect, efficiency and magnetization quality of the device.

[0015] Optionally, the thrust assembly one, thrust assembly two, and thrust assembly three all push the product to move in directions perpendicular to the direction of movement of the magnetic adsorption block.

[0016] By adopting the above technical solution, the magnetic adsorption block adsorbs and positions the product, and the direction of the pushing force when the product moves is perpendicular to the direction of movement of the magnetic adsorption block, which greatly reduces the force when the product separates from the magnetic adsorption block, reduces the risk of product damage, and improves product quality.

[0017] Optionally, the feeding mechanism includes: The vibratory feeder and the linear vibratory feeder are connected to each other. The vibratory feeder is used to vibrate and convey the product to the linear vibratory feeder, and the linear vibratory feeder is used to horizontally convey the product to the magnetizer for magnetization.

[0018] By adopting the above technical solution, the vibration of the vibratory feeder causes the products to come into contact with each other under the action of gravity and to be evenly arranged in sequence as required. The evenly arranged products are moved to the linear vibratory feeder, and the vibration of the linear vibratory feeder causes the products to be horizontally conveyed forward into the magnetizer for magnetization. This allows the product state to better adapt to the product state required by the magnetizer, thereby improving the magnetization effect, efficiency and magnetization quality of the device.

[0019] Optionally, the feeding mechanism further includes a guide component, which is used to push the product on the vibratory feeder forward or block the product movement; the return track includes two interconnected and perpendicular tracks three and four, two thrust components three are spaced apart and are used to push the product to move on tracks three and four respectively, the guide component blocks the product movement, and the product located on track four is pushed to the vibratory feeder located between the magnetizer and the guide component for conveying.

[0020] Using the above technical solution, the magnetizer will take a certain amount of time to magnetize the product. Therefore, if there are two situations, such as multiple products entering the magnetizer at the same time or multiple products partially entering the magnetizer, the magnetization effect and efficiency of the product will be greatly reduced. However, both the vibrating feeder and the linear vibrating feeder are in a continuous running state, and it is quite troublesome to control the movement and stopping of the product by relying on the two.

[0021] The rotating guide component pushes the product it contacts forward, thereby increasing the product's movement speed and creating a certain distance between it and the product behind it. When the guide component rotates again and contacts the next product, it performs the same operation. This allows multiple products that are in contact with each other to enter the magnetizer in sequence at intervals for magnetization, greatly reducing the risk of multiple products entering the magnetizer in whole or in part. This ensures that the magnetizer only magnetizes one product at a time, reducing the risk of interference when multiple products are being magnetized, and improving the magnetization effect and efficiency of the device.

[0022] Simultaneously, when the returned products need to be remagnetized, the guide component blocks the product's forward movement. The two thrust components work together to push the product, which has moved to track three, through track three and then onto track four. The product on track four is then pushed onto the vibratory feeder for conveying, allowing the product to be moved into the magnetizer for remagnetization. At the same time, the surface magnetic value of the product can be detected by the surface magnetic detection head, and the parameters of the magnetizer can be adjusted to ensure that the product meets the magnetization requirements after magnetization. This improves the magnetization effect and efficiency of the device. The guide component can meet the magnetization requirements of normal products (i.e., the first magnetization) and also meet the magnetization requirements of products that need to be remagnetized, facilitating the magnetization of different products and improving the magnetization effect, efficiency, and product magnetization quality of the device.

[0023] Optionally, the guiding component includes: The guide wheel is rotatably mounted on the machine body; An elastic layer is provided on the outer wall of the guide wheel and has elasticity; A rotating component is used to drive the guide wheel to rotate. The elastic layer is stationary and abuts against one end of the product for positioning, or the rotation of the elastic layer pushes the product forward.

[0024] By adopting the above technical solution, when the guide wheel and elastic layer are stationary, the product is positioned by approaching and pressing against the elastic layer under the action of the vibrating feeder, thereby blocking the product from moving. If the guide wheel and elastic layer rotate, the elastic layer is squeezed and rotated to push the product forward until the product separates from the elastic layer, thereby realizing the forward movement of the product and accelerating the movement speed of the product. This allows multiple products to be moved sequentially and intermittently to the magnetizer for magnetization, or multiple products to be blocked for positioning.

[0025] Optionally, a detection hole is provided on the vibratory feeder located between the guide assembly and the magnetizer. The vibratory feeder is provided with a detection component that passes through the detection hole and is used to detect the surface magnetism of the product and is electrically connected to the magnetizer and the surface magnetism detection head. The vibratory feeder is provided with a control component that controls the opening or blocking of the detection hole. When the thrust assembly three pushes the product located on track four closer to the vibratory feeder, the control assembly controls the detection hole to open and enables the detection element to detect the surface magnetism of the product. When the thrust assembly three moves back, the control assembly closes the detection hole.

[0026] By adopting the above technical solution, since the magnetization is done in batches, there may be multiple products on the return track at the same time. This can easily cause data errors when the magnetizer remagnetizes the products, making it impossible for the magnetizer to control the parameters in a timely and accurate manner, thus reducing the magnetization quality of the device.

[0027] During the initial magnetization of a batch, the control component blocks the detection hole, preventing the detection element from interfering with the magnetization of normal products. When remagnetization is required, the thrust component pushes the product onto the vibratory feeder, simultaneously opening the detection hole. This allows the detection element to re-detect the surface magnetism of the product, enabling the magnetizer to accurately and promptly obtain the product's surface magnetism data. This facilitates the control of the magnetizer's parameters for magnetization, further improving the magnetization effect, efficiency, and product magnetization quality of the device.

[0028] When the thrust assembly moves back three times, the control assembly moves back to block the detection hole, and then the guide assembly starts, so that the products on the direct vibration feeder continue to be magnetized for the first time, and the detection piece does not detect normal products, making the structure more stable, reducing the risk of data interference and errors, and improving the magnetization effect, efficiency and product magnetization quality of the device.

[0029] Optionally, the control component includes: A sealing plate is slidably mounted on the vibratory feeder and is used to open or block the detection hole; Push block, set on the sealing plate and extending vertically above the vibratory feeder; A spring is installed on the vibratory feeder and the pusher block to keep the sealing plate in the state of sealing the detection hole; A push rod is mounted on the third thrust assembly. When the third thrust assembly pushes the product onto the vibratory feeder, the push rod pushes the push block to move and causes the sealing plate to open the detection hole. After the third thrust assembly moves back, the sealing plate moves back under the action of the spring to seal the detection hole.

[0030] By adopting the above technical solution, during the process of the third thrust assembly pushing the product to the vibratory feeder, the drive push rod approaches and abuts against the push block, and pushes the push block and the sealing plate to move and open the detection hole. After the product is moved to the vibratory feeder, the detection component can detect the surface magnetism of the product through the detection hole. When the third thrust assembly moves back, the drive push rod moves away from the push block, and the push block and the sealing plate move back under the action of the spring to block the detection hole, so that the detection component cannot be detected.

[0031] Optionally, the thrust assembly includes: The thrust element and the thrust rod are connected to each other. The thrust element drives the thrust rod to move and is used to move the product.

[0032] By adopting the above technical solution, the thrust component starts to drive the thrust rod to move, and the movement of the thrust rod drives the product to move.

[0033] In summary, this application includes at least one of the following beneficial technical effects: 1. By automatically loading, magnetizing, and testing products, outputting qualified products and remagnetizing unqualified products, the system can greatly reduce manpower and enterprise costs, and improve magnetization effect, efficiency, and product magnetization quality.

[0034] 2. When the product is pushed to the magnetic detection head for testing by the missorting component, the product is positioned against the magnetic adsorption block. The magnetic detection head detects the surface magnetism of the product. After the test, qualified products are output and unqualified products are returned to the magnetizer for remagnetization. The remagnetized products continue to be tested and sorted. If the product is still unqualified, it is moved to the NG track. This reduces the number of products that cannot meet the magnetization requirements due to their own quality, and reduces the risk of such products occupying the device for a long time and reducing the magnetization efficiency. This further improves the magnetization effect, efficiency and magnetization quality of the device.

[0035] 3. During the initial magnetization of the product, the control component controls the sealing of the detection hole. When the product needs to be remagnetized, the thrust component pushes the product onto the vibratory feeder, which in turn pushes the control component to open the detection hole. The detection component can then re-detect the surface magnetism of the product through the detection hole. The magnetizer can accurately and promptly obtain the surface magnetism data of the product, thereby facilitating the control of the magnetizer parameters to magnetize the product, further improving the magnetization effect, efficiency, and product magnetization quality of the device.

[0038] The following provides a further detailed description of this application.

[0039] This application discloses an integrated device for magnetizing and detecting the surface magnetization of magnetic materials.

[0040] Reference Figure 1 and Figure 2The magnetic material magnetization and surface magnetization detection integrated device includes a feeding mechanism 2, a magnetizer 11, a detection mechanism 3, and a control mechanism 4. The feeding mechanism 2 is used to transport the product to the magnetizer 11 for magnetization. The detection mechanism 3 is used to detect the surface magnetism of the magnetized product. The control mechanism 4 is used to output the qualified product or return the unqualified product to the magnetizer 11 for remagnetization based on the detection result of the detection mechanism 3.

[0041] The magnetizer 11 is existing technology and will not be described in detail here. The magnetizer 11 is fixedly installed on the machine body 1 and is set along the length of the machine body 1. The feeding mechanism 2 transports the product into the magnetizer 11 along the length of the machine body 1 for magnetization. After magnetization is completed, the magnetizer 11 outputs the product along the length of the machine body 1.

[0042] Reference Figures 1-3 The feeding mechanism 2 includes a vibratory feeder 21 and a linear vibratory feeder 22. The vibratory feeder 21 is a vibratory feeding plate in the prior art. Both the vibratory feeder 21 and the linear vibratory feeder 22 are fixedly installed on the machine body 1 and are provided with an inclined downward discharge slide. When the vibratory feeder 21 is started, multiple products are pushed against each other and arranged in sequence on the discharge slide and move forward under the action of gravity. One end of the linear vibratory feeder 22 is connected to the bottom end of the discharge slide and the other end extends to the magnetizer 11. The linear vibratory feeder 22 is in a horizontal state and vibrates in a straight line, causing the products to move toward the magnetizer 11, so that the products enter the magnetizer 11 for the first magnetization.

[0043] Reference Figures 1-4 The testing mechanism 3 includes track 1 31 and track 2 32, a magnetic detection head, and a misalignment component 34. Track 1 31 and track 2 32 are connected at one end and their length directions are perpendicular to each other and are fixedly installed on the machine body 1. Track 1 31 is set along the length direction of the machine body 1 and one end extends to the magnetizer 11. Track 1 31 and the direct vibration feeder 22 extend to both ends of the magnetizer 11 respectively.

[0044] After the magnetizer 11 completes the magnetization, the product is moved into track 31 for transport. Track 2 32 is connected to the end of track 31 away from the magnetizer 11. Track 1 31 is equipped with a conveyor belt for transporting the product, so that the product moves until it comes into contact with the connection between track 1 31 and track 2 32 for positioning. The magnetic detection head is fixedly installed on the lower surface of track 2 32 and is set vertically upward. The misalignment component 34 is used to push the product that comes into contact with the connection between track 1 31 and track 2 32 to the magnetic detection head for detection. At this time, the control mechanism 4 is attached to the product for positioning.

[0045] The surface magnetization detection head is used to detect the surface magnetism of the product. The control mechanism 4 determines whether the product is qualified if the surface magnetism is saturated, or unqualified if it is not. The control mechanism 4 is used to output qualified products and return unqualified products to the magnetizer 11 for remagnetization.

[0046] Reference Figure 1 , Figure 2 , Figure 4 The misalignment assembly 34 includes a misalignment component 35 and a misalignment rod 36. The misalignment component 35 is an electric push rod, which is fixedly installed on the machine body 1 and located on one side of track 1 31. The piston rod of the misalignment component 35 is parallel to the length direction of track 2 32. The misalignment rod 36 is fixedly installed on the piston rod of the misalignment component 35 and extends through track 1 31 to the connection between track 1 31 and track 2 32. The misalignment rod 36 is located on the side of track 1 31 away from track 2 32. When the misalignment component 35 is activated, it pushes the product against the connection between track 1 31 and track 2 32 to the magnetic detection head through the misalignment rod 36, so that the product is against the control mechanism 4 and is attracted and positioned by the control mechanism 4.

[0047] The control mechanism 4 includes a qualified track 41, an NG track 42, a return track 43, a magnetic adsorption block 44, a thrust assembly 5, a thrust assembly 2 45, and a thrust assembly 3 46. The qualified track 41, NG track 42, and return track 43 are arranged along the length direction of track 2 32, and the distance from the magnetizer 11 increases. The qualified track 41, NG track 42, and return track 43 are fixedly installed on the body 1, and the length direction of the three is perpendicular to the length direction of track 2 32 and located on one side of track 2 32. At the same time, the qualified track 41 and NG track 42 are located on the side of track 2 32 away from the magnetizer 11.

[0048] The qualified track 41, NG track 42 and return track 43 are all connected to the inner track 32. When the product moves to the magnetic detection head, the product is connected to the qualified track 41. A sliding hole 37 is opened on the inner track 32 along its own length direction. The sliding hole 37 is located on the side of the magnetic detection head away from the first track 31. The magnetic adsorption block 44 is slidably installed on the sliding hole 37 along the length direction of the inner track 32 and has magnetism. When the product is pushed to the magnetic detection head by the staggered rod 36, the product is positioned against the magnetic adsorption block 44. The magnetic adsorption block 44 adsorbs and positions the product. A moving part 38 that drives the magnetic adsorption block 44 to move is fixedly installed on the body 1. The moving part 38 can be an electric push rod or a motor nut screw, etc.

[0049] The return track 43 includes track 3 431 and track 432. Track 3 431 and track 432 are connected to each other and perpendicular in length direction and are fixedly installed on the machine body 1. Track 3 431 is parallel to the length of the machine body 1 and is located on the side of track 2 32 away from qualified track 41 and NG track 42, so that qualified track 41 and NG track 42 are located between magnetizer 11 and track 3 431. One end of track 3 431 abuts against track 2 32; one end of track 432 abuts against the end of track 3 431 away from track 2 32, and the other end of track 432 extends to the direct vibration feeder 22.

[0050] Thrust assembly 1 (5), thrust assembly 2 (45), and thrust assembly 3 (46) are respectively set to the qualified track 41, the NG track 42, and the return track 43, and are used to push the product located at the magnetic adsorption block 44 to the corresponding position. The direction of product movement by the three components is perpendicular to the direction of movement of the magnetic adsorption block 44, and the three components have the same structure. The following explanation will take thrust assembly 1 (5) as an example.

[0051] The thrust assembly 5 includes a thrust member 51 and a thrust rod 52. The thrust member 51 is an electric actuator. The thrust member 51 is fixedly installed on the machine body 1 and located on the side of the second track 32 away from the qualified track 41. The piston rod of the thrust member 51 is arranged in a direction perpendicular to the length of the second track 32. The thrust rod 52 is fixedly installed on the piston rod of the thrust member 51 and extends into the second track 32.

[0052] The thrust component 51 activates and drives the thrust rod 52 to approach the product, thereby pushing the product to the qualified track 41, or the NG track 42, or the return track 43. Two thrust components 46 are arranged at intervals and correspond to the tracks 431 and 432. One thrust component 46 is activated to push the product located at the magnetic adsorption block 44 through the track 431 to the track 432 and then moves back to its original position. The other thrust component 46 is activated to push the product located on the track 432 to the vibratory feeder 22. Then the thrust component 46 moves back and the vibratory feeder 22 transports the product to the magnetizer 11 for remagnetization.

[0053] If the magnetic detection head detects that the product is qualified, the first thrust assembly 5 is activated to push the product onto the qualified track 41 for conveying. If the magnetic detection head detects that the product's surface magnetism is not saturated, the magnetic adsorption block 44 pulls the product to track 431. The two push assemblies 24 are activated in sequence to push the product onto the vibrating feeder 22. The vibrating feeder 22 is activated to convey the product into the magnetizer 11 for remagnetization. Then the product is tested again by the magnetic detection head. If the product is qualified, it enters the qualified track 41. If the magnetic detection head detects that the product is still unqualified after remagnetization, the magnetic adsorption block 44 pulls the product to track 42. The second thrust assembly 45 is activated to push the product to track 42 for conveying, thereby realizing the separation of products into multiple types for conveying.

[0054] Reference Figures 1-3 The feeding mechanism 2 also includes a guide component 23 and a push component 24. The guide component 23 and the push component 24 have the same structure and are respectively set to the vertical vibrating feeder 22 and the track 31. The guide component 23 is used to push the product on the vertical vibrating feeder 22 forward or block the product movement. The push component 24 is used to push the product located on the track 31 forward at an accelerated speed. The guide component 23 will be used as an example for explanation below.

[0055] The guide assembly 23 includes a guide wheel 25, an elastic layer 26, and a rotating component 27. The guide wheel 25 is horizontally rotatably mounted on the machine body 1 and extends above the vibratory feeder 22. The axis of the guide wheel 25 is perpendicular to the moving direction of the vibratory feeder 22 conveying the product. The elastic layer 26 is fixedly mounted on the outer wall of the guide wheel 25 and has elasticity. The rotating component 27 is a motor, which is fixedly mounted on the machine body 1 and its output shaft is fixedly connected to the guide wheel 25. The rotating component 27 is used to drive the guide wheel 25 to rotate.

[0056] The vibratory feeder 22 drives the product forward and presses it against the elastic layer 26 for positioning. The rotating component 27 starts the drive guide wheel 25 and the elastic layer 26 to rotate. The elastic layer 26 rotates and is squeezed by the product, pushing the product forward. Under the push of the elastic layer 26 and the drive of the vibratory feeder 22, the product moves forward, which speeds up the product movement. This creates a certain distance between the product in contact with the elastic layer 26 and the next product, so that multiple products can enter the magnetizer 11 in sequence for magnetization. After the previous product enters the magnetizer 11 and is magnetized and output, the next product enters the magnetizer 11 again for magnetization. This reduces the adverse interference generated during product magnetization and makes the product magnetization effect better.

[0057] Meanwhile, track 432 is located between magnetizer 11 and guide assembly 23. When the product in track 432 needs to be remagnetized, guide wheel 25 stops the product on the side of vibratory feeder 22 closest to vibratory feeder 21 from moving forward. After all the products on vibratory feeder 22 on the side of guide wheel 25 closest to magnetizer 11 have entered magnetizer 11 for magnetization, thrust assembly 3 46 pushes the product on track 432 onto vibratory feeder 22. Magnetizer 11 outputs the magnetized product, and vibratory feeder 22 inputs the product pushed in by track 432 into magnetizer 11 for remagnetization. Thrust assembly 3 46 continues to start, pushing the product that needs to be remagnetized into vibratory feeder 22, thus completing the remagnetization of the product. After the remagnetized product is completed, guide wheel 25 continues to rotate, thus continuing to achieve the first magnetization of the product.

[0058] Reference Figure 1 , Figure 2 , Figure 5 A detection hole 12 is provided on the vibratory feeder 22 located between the guide assembly 23 and the magnetizer 11. A detection element 13 is fixed on the lower surface of the vibratory feeder 22, which passes through the detection hole 12 and is used to detect the surface magnetism of the product. The detection element 13 is the same as the surface magnetism detection head and is used to detect the surface magnetism of the product. At the same time, the detection element 13 is electrically connected to the magnetizer 11 and the surface magnetism detection head. A control assembly 6 is provided on the vibratory feeder 22 to control the opening or blocking of the detection hole 12.

[0059] When the thrust assembly 3 46 pushes the product located on track 432 closer to the vibratory feeder 22, the thrust assembly 3 46 moves and controls the detection hole 12 to open through the control assembly 6, and the detection element 13 detects the surface magnetism of the product. The magnetizer 11 adjusts the magnetization parameters of the product according to the surface magnetism value detected by the detection element 13, so that the product meets the magnetization requirements after magnetization, and also reduces the energy waste caused by the magnetizer 11 over-magnetizing the product. At the same time, the detection element 13 can only detect the surface magnetism of the product when it is remagnetized. Therefore, when the surface magnetism detection head detects the product, it can determine from the detection element 13 that this product is being remagnetized rather than being magnetized for the first time. This reduces the risk of the product continuing to enter the return track 43 if it is still unqualified after remagnetization, and reduces the waste of time.

[0060] The control component 6 includes a sealing plate 61, a push block 62, a spring, and a push rod 63. The vertical vibratory feeder 22 has a horizontal movable hole on the side wall away from the push component 46 that communicates with the detection hole 12. The sealing plate 61 is slidably installed on the detection hole 12 and is used to open or block the detection hole 12. The push block 62 is fixedly installed on the upper surface of the end of the sealing plate 61 away from the detection hole 12 and extends vertically above the vertical vibratory feeder 22. The spring is fixedly installed on the push block 62 and the side wall of the vertical vibratory feeder 22. When the product is first magnetized, the spring pulls the sealing plate 61 to block the detection hole 12.

[0061] The push rod 63 is fixedly installed on the thrust assembly 46. When the thrust assembly 46 pushes the product closer to the vibratory feeder 22, the push rod 63 approaches and abuts against the push block 62. When the product is moved onto the vibratory feeder 22, the push rod 63 pushes the sealing plate 61 through the push block 62 to open the detection hole 12. The detection element 13 detects the surface magnetism of the product. The thrust assembly 46 moves back to its original position, causing the push rod 63 to disengage from the push block 62. The sealing plate 61 moves back under the action of the spring and seals the detection hole 12.

[0062] The working principle of this application embodiment is as follows: The vibratory feeder 21 starts and evenly conveys the product to the linear vibratory feeder 22 for further conveying. The rotating part 27 starts and drives the elastic layer 26 to rotate, driving the product to be sequentially and intermittently fed into the magnetizer 11 for magnetization. Then, the product moves through the first track 31 to the connection between the first track 31 and the second track 32 for positioning. The staggered rod 36 pushes the product to the surface magnetic detection head for surface magnetic detection, and the product is positioned against the magnetic adsorption block 44.

[0063] If the surface magnetism of the product is qualified, the first thrust assembly 5 pushes the product to the qualified track 41 for conveying. If the surface magnetism of the product is unqualified, the magnetic adsorption block 44 moves and pulls the product to the third track 431. The third thrust assembly 46 starts and pushes the product to the fourth track 432 for placement. When it is necessary to remagnetize the product on the fourth track 432, the elastic layer 26 stops rotating to block the product from moving forward. The other thrust assembly 46 starts and pushes the product on the fourth track 432 to the vibrating feeder 22. At the same time, the third thrust assembly 46 controls the opening of the detection hole 12, and the detection element 13 starts to detect the surface magnetism of the product. The vibrating feeder 22 inputs the product into the magnetizer 11 for remagnetization. After remagnetization, the product continues to be detected by the surface magnetism detection head. If the product is qualified, it enters the qualified track 41. Otherwise, if the product is still unqualified, the magnetic adsorption block 44 moves and pulls the product to the NG track 42. The second thrust assembly 45 pushes the product into the NG track 42 for conveying.

[0064] After the product is remagnetized, the elastic layer 26 continues to rotate and push the product forward to complete the initial magnetization. By automatically realizing the magnetization of the product, the surface magnetization test, and the return of products with unqualified surface magnetization for remagnetization, the waste of manpower and the cost of the enterprise are reduced, and the magnetization quality of the product is improved.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
