Therefore, it is necessary to use the positioning components and gripper components of the device to form a double limit, ensuring the magnets remain stable throughout the pressing process and providing a reliable guarantee for precise and high-quality pressing operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-4 A magnet pressing and positioning device includes a processing table 1, and a limiting component for placing magnets is slidably disposed on the top of the processing table 1;

[0026] The limiting assembly includes a movable seat 2, a fixed platform 3, a first movable groove 4, a two-way lead screw 5, a slider 6, a side plate 7, a spring-type telescopic rod 8, and a rubber stop 9. The movable seat 2 is slidably mounted on the top of the processing table 1, and the fixed platform 3 is fixedly installed on the top of the movable seat 2. The fixed platform 3 has a first movable groove 4 inside. The two-way lead screw 5 is rotatably connected between the inner walls of the front and rear sides of the first movable groove 4. The two-way lead screw 5 is threaded to both ends of the front and rear sides, and the slider 6 is threaded to both ends. The top of the two sliders 6 is fixedly installed on the top of the two sliders 6. Several spring-type telescopic rods 8 are fixedly connected inside the two side plates 7, and the end of each spring-type telescopic rod 8 away from the side plate 7 extends to the outside of the corresponding side plate 7. The end of each spring-type telescopic rod 8 away from the side plate 7 is fixedly installed with a rubber stop 9.

[0027] Furthermore, a first motor 10 is fixedly installed on the rear side of the fixed platform 3. The output end of the first motor 10 is fixedly connected to the rear end of the bidirectional lead screw 5 through the fixed platform 3. Specifically, the first motor 10 serves as the power source for the bidirectional lead screw 5. When the equipment is started, the first motor 10 can drive the bidirectional lead screw 5 to rotate clockwise or counterclockwise. By utilizing the opposite thread characteristics at both ends of the bidirectional lead screw 5, the two sliders 6 are driven to move towards or away from each other along the first movable groove 4, thereby driving the two side plates 7 to move closer or further away synchronously, realizing the adjustment of the clamping range for magnets of different sizes, and providing adaptability for subsequent limit fixing.

[0028] Furthermore, a first cylinder 11 is fixedly installed on the top of the processing table 1. A first drive rod 12 is fixedly connected to the output end of the first cylinder 11. The end of the first drive rod 12 away from the first cylinder 11 is fixedly connected to one side of the movable seat 2. Specifically, the first cylinder 11 can drive the first drive rod 12 to perform telescopic movements through air pressure. When the first drive rod 12 extends, it will push the movable seat 2 to slide along the top of the processing table 1. When the first drive rod 12 retracts, it will pull the movable seat 2 to slide in the opposite direction, thereby realizing the adjustment of the overall position of the limiting component and conveying the limiting component with the magnet placed to the pressing station.

[0029] Furthermore, a support frame 13 is fixedly installed on the top of the processing table 1. An opening 14 is provided at the bottom of the support frame 13. The first cylinder 11 passes through the opening 14. Two support blocks 15 are also fixedly installed on the top of the processing table 1. A first slide rod 16 is fixedly connected between one side of the two support frames 13 and the side adjacent to the support frame 13. Both first slide rods 16 pass through the interior of the movable seat 2. The movable seat 2 is slidably positioned outside the two first slide rods 16. Specifically, the support frame 13 provides support for the top structure of the equipment, and the bottom opening 14 provides space for the installation and operation of the first cylinder 11. The support blocks 15 are used to fix the first slide rods 16, while the first slide rods 16 guide and limit the sliding of the movable seat 2, ensuring that the movable seat 2 remains stable during the sliding process and avoiding the impact of displacement on the positioning accuracy of the magnet.

[0030] Furthermore, the support frame 13 is in a sideways L-shape, and a second movable groove 17 is provided on the top of the support frame 13. A screw 18 is rotatably connected between the inner walls of the front and rear sides of the second movable groove 17. A second motor 19 is fixedly installed on the front side of the support frame 13, and the output end of the second motor 19 is fixedly connected to the front end of the screw 18. A slide 20 is threadedly connected to the outside of the screw 18. Specifically, the sideways L-shaped support frame 13 saves installation space and provides stable support for the pressing structure at the top. After the second motor 19 is started, it can drive the screw 18 to rotate in the second movable groove 17. Through the threaded engagement between the screw 18 and the slide 20, the slide 20 is driven to slide back and forth along the second movable groove 17, thereby adjusting the front and rear positions of the slide 20 and the subsequent pressing components, ensuring that the pressing components can be accurately aligned with the magnet in the lower limiting component.

[0031] Furthermore, a second slide rod 21 is fixedly installed between the inner walls of the front and rear sides of the second movable groove 17. The slide seat 20 is slidably disposed outside the second slide rod 21. A second cylinder 22 is fixedly installed on the top of the slide seat 20. A second drive rod 23 is fixedly connected to the bottom output end of the second cylinder 22. The end of the second drive rod 23 away from the second cylinder 22 extends to the bottom of the slide seat 20. Specifically, the second slide rod 21 is arranged parallel to the screw 18, which plays an auxiliary guiding role in the sliding of the slide seat 20, preventing the slide seat 20 from rotating or deviating under the drive of the screw 18, and ensuring the smooth sliding of the slide seat 20. The second cylinder 22 serves as the power source for the pressing action and can drive the second drive rod 23 to extend and retract up and down. When the second drive rod 23 extends downward, it will drive the pressing component at the bottom to approach the magnet and perform the pressing operation. After the pressing is completed, the second drive rod 23 retracts, driving the pressing component to reset.

[0032] Furthermore, a connecting plate 24 is fixedly installed at the bottom of the second drive rod 23. Four spring-loaded buffer rods 25 are slidably arranged on the surface of the connecting plate 24. A hot press plate 26 is fixedly installed at the bottom of the four buffer rods 25. Specifically, the connecting plate 24 is used to connect the second drive rod 23 and the buffer rods 25, and plays a role in force transmission. The four spring-loaded buffer rods 25 are evenly distributed between the connecting plate 24 and the hot press plate 26. During the pressing process, the springs can generate elastic deformation according to the actual pressing force. On the one hand, it can buffer the instantaneous pressure of the hot press plate 26 on the magnet, and avoid excessive pressure from damaging the magnet or workpiece. On the other hand, it can ensure that the hot press plate 26 is tightly attached to the magnet surface, and ensure the uniformity of pressing. The hot press plate 26 can provide stable heat during the pressing process, meet the temperature conditions required for pressing some magnets, and promote the firm bonding between the magnet and the workpiece.

[0033] In summary: First, during the magnet limiting stage, the core power of the limiting component comes from the first motor 10, which drives the bidirectional lead screw 5 to rotate clockwise or counterclockwise. Utilizing the opposite threads at both ends of the bidirectional lead screw 5, the slider 6 moves towards or away from the side plate 7. Combined with the elastic buffer of the spring-loaded telescopic rod 8 and the flexible contact of the rubber abutment 9, this not only accommodates magnets of different sizes but also prevents damage to the magnets during clamping, ultimately achieving a secure limiting of the magnets. After limiting, the first cylinder 11 is activated, and through the telescopic action of the first drive rod 12, it pushes the moving seat 2 to slide along the top of the processing table 1. At this time, the first slide rod 16 plays a crucial guiding role, limiting the moving seat 2 to slide only along a fixed trajectory, effectively preventing deviation, and smoothly transporting the magnet-limited component to the preset pressing station, laying a precise foundation for subsequent pressing operations. Entering the pressing preparation stage, the second motor 19 on the support frame 13 starts working, driving the screw 18 to rotate in the second movable groove 17, and driving the slide 20 to move through the threaded transmission; while the second slide rod 21 is set parallel to the screw 18, playing an auxiliary guiding and anti-rotation role for the slide 20, ensuring that the slide 20 drives the pressing component to be accurately adjusted to the position aligned with the magnet below. Finally, the second cylinder 22 drives the second drive rod 23 to extend downward, and the connecting plate 24 transmits power to the buffer rod 25 and the hot press plate 26; the four spring-loaded buffer rods 25 can flexibly deform according to the pressing force, which not only buffers the instantaneous pressure to avoid damage to the magnet, but also ensures that the hot press plate 26 is in close contact with the magnet surface, while the hot press plate 26 outputs stable heat to meet the pressing temperature requirements, thus efficiently completing the precise and stable pressing of the magnet, taking into account both efficiency and quality throughout the process.
