Description

A radial magnetization device Technical Field

[0001] This utility model belongs to the field of magnetization technology, specifically relating to a magnetization device for radial direction. Background Technology

[0002] Magnetizing equipment is a specialized device used to apply a magnetic field to magnetic materials, enabling them to acquire or regain magnetism. Its working principle is based on electromagnetic induction and current pulse technology. By generating a strong magnetic field, it causes the magnetic domains within the magnetic material to align in an orderly manner, thereby achieving permanent magnetization. Currently, most magnetizing equipment still relies on manual operation, resulting in low magnetization efficiency and wasted manpower and resources. Furthermore, human factors such as operating techniques can affect the magnetization effect, leading to unstable magnetization quality, and improper operation can also cause safety hazards. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a radiation direction magnetization device with a reasonable design, clear division of labor among various mechanisms, and mutual cooperation. It can efficiently and accurately complete the magnetization process of the product, ensure the stability and reliability of the magnetization operation, and the entire device has a high degree of automation, saving a lot of time, greatly improving the safety of operation, reducing the intensity of manual labor, reducing manual intervention, and helping to improve production efficiency and product quality stability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A radial magnetization device includes a frame, a product placement mechanism, a product conveying mechanism, a clamping mechanism, a magnetization mechanism, and a lifting mechanism. The frame contains a worktable that divides the frame into an upper and lower cavity. The product placement, conveying, and clamping mechanisms are all located in the upper cavity. The product placement mechanism places the product, the conveying mechanism grips and delivers the product, and the clamping mechanism presses the product down. The magnetization and lifting mechanisms are both located in the lower cavity. A magnetization channel runs through the center of the magnetization mechanism, ensuring the product is in a concentrated and stable magnetic field environment during magnetization. This allows for more targeted radial magnetization, effectively improving magnetization efficiency. The magnetization mechanism magnetizes the product, and the lifting mechanism lifts and positions it. The device features a rational structural design with clear division of labor among the various mechanisms, ensuring efficient and accurate magnetization. This guarantees the stability and reliability of the magnetization operation. The high degree of automation saves significant time, greatly improves operational safety, enhances product quality and work efficiency, and reduces manual labor intensity.

[0006] Furthermore, the product conveying mechanism includes a conveying cylinder, a moving frame, and pneumatic grippers. The conveying cylinder is fixed on the worktable, and its push rod is connected to the moving frame. The moving frame is slidably engaged on the sliding track, and the pneumatic grippers are fixed on the moving frame. The conveying cylinder drives the moving frame to move back and forth along the sliding track, and the moving frame then drives the pneumatic grippers to move back and forth synchronously. The structure is simple and compact. The conveying cylinder, as a power source, provides a stable linear driving force, allowing the moving frame to move smoothly back and forth along the sliding track, thus adjusting the position of the pneumatic grippers. The sliding track provides precise guidance for the moving frame, ensuring the positional accuracy of the pneumatic grippers when gripping and conveying products, improving the accuracy of product placement and gripping, and avoiding the impact of positional deviations on equipment operation. The pneumatic grippers have good flexibility, enabling them to quickly complete the gripping and releasing of products, improving product conveying efficiency. The entire product conveying process is automated, reducing manual intervention and improving production efficiency and stability.

[0007] Furthermore, the clamping mechanism includes a clamping cylinder, an upper sliding plate, a clamping rod, and a clamping head. The clamping cylinder is fixed on the upper support plate, which is fixedly connected to the worktable via an upper guide rod. The upper guide rod extends longitudinally through the upper sliding plate, and an upper sliding sleeve is provided at the connection between the upper sliding plate and the upper guide rod. The push rod of the clamping cylinder is connected to the upper sliding plate, and the top end of the clamping rod is connected to the upper sliding plate. The clamping head is fixedly installed at the bottom end of the clamping rod. The clamping cylinder drives the upper sliding plate to move up and down along the upper guide rod, and the upper sliding plate then drives the clamping rod and the clamping head to move up and down synchronously, thereby achieving the clamping or releasing of the product by the clamping head. The upper guide rod and the upper sliding sleeve work together to provide stable guidance for the up and down movement of the upper sliding plate, ensuring the verticality and accuracy of the clamping action, and ensuring that the clamping head can accurately act on the product, avoiding the magnetization process from being affected by deviation.

[0008] Furthermore, a measuring coil is installed on the workbench, with a measuring channel running through its center. The measuring coil performs magnetic flux detection on the magnetized product. This allows for real-time quality monitoring of the magnetization process. Similar to the magnetization channel, the measuring channel provides a stable and precise testing environment, ensuring accurate magnetic flux detection. Both the clamping rod and the clamping head can pass through both the measuring and magnetization channels, as can the product itself. This design allows the product to smoothly enter the magnetization channel from the measuring channel. The clamping head moves downwards with the product, ensuring it descends into the magnetization channel under clamping conditions. This prevents the product from shaking or shifting during descent, ensuring it accurately reaches the magnetization area and guaranteeing accurate magnetization positioning.

[0009] Furthermore, the lifting mechanism includes an electric cylinder, a sliding plate, a lifting rod, and a positioning core. The electric cylinder is fixed to the lower support plate, which is fixedly connected to the worktable via a lower guide rod. The lower guide rod extends longitudinally through the sliding plate, and a sliding sleeve is provided at the connection between the sliding plate and the lower guide rod. The push rod of the electric cylinder is connected to the sliding plate, and the bottom end of the lifting rod is connected to the sliding plate. The positioning core is fixedly installed at the top end of the lifting rod and has a positioning slot. The electric cylinder drives the sliding plate to move up and down along the lower guide rod, and the upper sliding plate then drives the lifting rod and the positioning core to move up and down synchronously. The cooperation between the lower guide rod and the sliding sleeve facilitates the downward movement of the sliding plate. The vertical movement of the sliding plate improves stable guidance, ensuring the verticality and stability of the lifting action, allowing the positioning core to rise accurately to the designated position for reliable product positioning. The positioning slot mates with the product, facilitating the placement of the product on the positioning core. The positioning core and the lifting rod can be designed with a threaded connection for fixation. The appropriate positioning core can be replaced according to the product size, making it adaptable to the placement and positioning of products of different sizes, improving the versatility and flexibility of the equipment. Both the lifting rod and the positioning core can pass through the magnetization channel and the measurement channel, ensuring the smooth progress of the product magnetization and magnetic flux detection process.

[0010] Furthermore, the product placement mechanism includes a placement platform, a defective product channel, and a reversing cylinder. Both the placement platform and the defective product channel are mounted on a movable base, which is slidably engaged with a second sliding track. The push rod of the reversing cylinder is connected to the movable base, causing it to move left and right. The movable base then moves the placement platform and the defective product channel simultaneously left and right. A perforated slot is provided on the worktable, through which the defective product channel extends into the lower cavity. A defective product box, which connects to the defective product channel, is installed in the lower cavity, allowing for adjustment of the workstation positions of the placement platform and the defective product channel. The system can be adjusted flexibly according to the product condition after magnetic flux testing by adjusting the position of the placement platform and the defective product channel station. When the product passes the magnetic flux test, the reversing cylinder moves the placement platform to the front of the pneumatic gripper, so that the pneumatic gripper can pick up the qualified product and put it back on the placement platform. When the product fails the magnetic flux test, the reversing cylinder moves the defective product channel to the front of the pneumatic gripper, so that the pneumatic gripper can pick up the unqualified product and put it into the defective product channel, and then slide it into the defective product box in the lower cavity.

[0011] Furthermore, the placement table is provided with a placement slot with an opening. The placement slot facilitates the placement and positioning of the workpiece on the placement table. The opening faces the direction of the pneumatic gripper, which facilitates the pneumatic gripper to pick up or place the product into the placement slot.

[0012] Furthermore, the frame is equipped with three-color lights, with red, yellow, and green representing different states, so that operators can quickly and intuitively understand the operating status of the equipment and improve work efficiency.

[0013] Furthermore, a touch screen and operation buttons are installed on the front side of the rack to improve the convenience and efficiency of equipment operation.

[0014] Furthermore, casters are installed at the bottom of the frame, which facilitates the movement and transportation of the entire equipment and enhances its flexibility.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This utility model is rationally designed and highly practical. The division of labor among the various mechanisms is clear, while they cooperate with each other to efficiently and accurately complete the magnetization process of the product, ensuring the stability and reliability of the magnetization operation. The entire equipment has a high degree of automation, saving a lot of time, greatly improving the safety of operation, reducing the intensity of manual labor, and minimizing human intervention. This is conducive to improving production efficiency and product quality stability. Furthermore, it performs magnetic flux detection on the magnetized product, realizing real-time quality monitoring of the magnetization process. Attached Figure Description

The electric cylinder 21 drives the positioning core 24 to rise to the set height, and the bottom of product 41 is just supported and limited into the positioning slot 38 of the positioning core 24. The pneumatic gripper 11 releases product 41, and the clamping cylinder 13 drives the clamping head 16 to move down to press down on product 41. At the same time, the electric cylinder 21 moves down, so that product 41 moves down into the magnetization channel 20 under the clamped state. The magnetization mechanism 6 starts to magnetize product 41. After magnetization is completed, the clamping cylinder 13 moves back to its original position. Electric cylinder 21 drives positioning core 24 to rise until product 41 moves to the set position of measuring channel 19. Measuring coil 8 measures the magnetic flux of product 41. After the test is completed, electric cylinder 21 drives product 41 to move out of measuring channel 19. Product 41 that passes the test is clamped by pneumatic gripper 11 and sent back to placement slot 33. If product 41 fails the test, reversing cylinder 31 starts to push defective product channel 30 to the set position, so that defective product channel 30 moves exactly in front of pneumatic gripper 11. Product 41 that fails the test is clamped by pneumatic gripper 11 and sent to defective product channel 30, and then flows into defective product box for collection.
