Description

Technical Field

[0001] This utility model relates to the technical field of screening auxiliary devices, specifically a screening auxiliary device after die casting of a ring magnetic core. Background Technology

[0002] In the field of electronic component manufacturing, toroidal magnetic cores are core components of equipment such as transformers and inductors. The quality screening of toroidal magnetic cores after die casting directly affects the performance of downstream products. Currently, the screening of toroidal magnetic cores after die casting relies heavily on manual operation. Workers need to visually inspect for appearance defects, measure dimensional accuracy with calipers, and then test magnetic properties with specialized instruments. The entire process requires multiple steps and is time-consuming for each batch. Furthermore, manual visual inspection is susceptible to fatigue and differences in experience, leading to missed defects such as cracks and micropores. The dimensional measurement error is also difficult to control within the industrial standard of ±0.05mm, which seriously affects the stability of screening quality.

[0003] With the surge in demand for toroidal magnetic cores from industries such as new energy vehicles and 5G communications, the inefficiency of traditional manual sorting methods in large-scale production has become increasingly apparent. The conventional manual sorting speed is approximately 20-30 cores per minute, which is insufficient to match the 60 cores per minute output of a die-casting production line. This often results in cores piling up and waiting to be sorted, causing production interruptions. Furthermore, improper force control during manual handling and transfer of cores can easily cause damage or deformation to the core edges, further increasing the defect rate and adding to production costs.

[0004] Existing automated screening equipment often suffers from limited functionality: some devices can only perform dimensional or appearance inspections, while magnetic property testing still requires a separate process; some devices, although integrating multi-dimensional inspections, have poor adaptability in their gripping mechanisms, only capable of handling fixed-size toroidal cores. Changing specifications requires disassembling and replacing the grippers, which is time-consuming and labor-intensive. Furthermore, most equipment is not integrated with the die-casting production line conveyor belt, requiring manual transfer of the cores from the conveyor belt to the screening equipment, which fails to meet the demands of modern production for continuous and efficient processes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an auxiliary device for screening ring-shaped magnetic cores after die casting, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A screening auxiliary device after die casting of annular magnetic cores includes a gantry frame with foot cups at the bottom. Two guide rods are fixedly connected to the top of the gantry frame, and sliders are slidably connected to the guide rods. A movable seat is fixedly connected to the upper part of the slider, and a drive motor is fixedly connected to one side of the movable seat. A drive gear is fixedly connected to the output end of the drive motor, and the drive gear meshes with a rack. A mounting plate is fixedly installed on the top of the movable seat, and a lifting cylinder is fixedly installed on the mounting plate. Limit rods are installed at the four corners of the mounting plate. A movable plate is fixedly connected to the output end of the lifting cylinder, and a propulsion cylinder is fixedly connected to the bottom of the movable plate. A connecting plate is fixedly connected to the front end of the propulsion cylinder, and a hexagonal block is fixedly connected to the output end of the propulsion cylinder through the connecting plate. Three rotating blocks are rotatably connected to the side wall of the hexagonal block, and three grippers are rotatably connected to one end of each rotating block.

[0007] Furthermore, the rack is fixedly mounted on the gantry frame on one side of the guide rod for horizontal movement of the moving seat.

[0008] Furthermore, positioning sleeves are installed at the four corners of the movable plate, and the positioning sleeves slide within the limiting rod.

[0009] Furthermore, the grippers are distributed circumferentially.

[0010] Furthermore, the top of the gripper is rotatably connected to the connecting plate.

[0011] Furthermore, below the gantry frame of the screening auxiliary device after die-casting of the annular magnetic core are the annular magnetic cores placed on the conveyor belt to identify the quality of the products, which are then picked up by grippers.

[0012] Furthermore, after the annular magnetic core is die-cast, the screening auxiliary device moves to one side after being gripped by the grippers to pick out the damaged products.

[0013] Compared with the prior art, the present invention provides a screening auxiliary device after die casting of annular magnetic cores, which has the following beneficial effects: This invention utilizes a drive motor, a gear rack and pinion mechanism, and a guide rod slider to achieve precise horizontal movement of the gripper. A lifting cylinder and a limiting rod positioning sleeve ensure vertical lifting accuracy. A propulsion cylinder then links with the gripper to achieve stable clamping. It is adaptable to magnetic cores of different specifications. The device connects to the initial identification stage and the conveyor belt, enabling rapid clamping and sorting of good and bad magnetic cores. It replaces manual labor, reducing missed inspections and collisions, improving screening efficiency and quality, meeting the needs of large-scale production, and reducing enterprise labor and production costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides a screening auxiliary device after die casting of annular magnetic cores, including a gantry frame 1. The bottom of the gantry frame 1 is provided with a foot cup 2, and the top of the gantry frame 1 is fixedly connected to two guide rods 3. A slider 4 is slidably connected to the guide rods 3. The gantry frame 1 serves as the main frame of the device, and the bottom foot cup 2 is adjusted to keep the gantry frame 1 horizontal and stable. The guide rods 3 and the rack 8 are fixed parallel to each other on the top of the gantry frame 1, providing sliding guidance for the slider 4. The upper part of the slider 4 is fixedly connected to the movable seat 5, and one side of the movable seat 5 is fixedly connected to the drive motor 6. The output end of the drive motor 6 is fixedly connected to the drive gear 7. The drive gear 7 meshes with the rack 8. The top of the movable seat 5 is fixedly installed with an mounting plate 9. The drive motor 6 outputs torque to drive the drive gear 7 to rotate. Because the drive gear 7 meshes with the rack 8 fixed on the gantry 1, the rotational motion is converted into linear motion, which in turn pushes the slider 4 to slide along the guide rod 3. The slider 4 is fixedly connected to the movable seat 5, and finally drives the movable seat 5 and the top mounting plate 9 to move horizontally along the direction of the guide rod 3. A lifting cylinder 10 is fixedly installed on the mounting plate 9. Limiting rods 11 are installed at the four corners of the mounting plate 9. A moving plate 12 is fixedly connected to the output end of the lifting cylinder 10. A pushing cylinder 13 is fixedly connected to the bottom of the moving plate 12. When the piston rod of the lifting cylinder 10 extends or retracts, it pushes the moving plate 12 fixed thereto to move. The positioning sleeves at the four corners of the moving plate 12 are sleeved on the limiting rods 11 at the four corners of the mounting plate 9, restricting the moving plate 12 to slide only in the vertical direction, thereby driving the pushing cylinder 13 and the gripper 17 at the bottom of the moving plate 12 to rise and fall synchronously. A connecting plate 14 is fixedly connected to the front end of the propulsion cylinder 13. A hexagonal block 15 is fixedly connected to the output end of the propulsion cylinder 13 through the connecting plate 14. Three rotating blocks 16 are rotatably connected to the side wall of the hexagonal block 15. Three grippers 17 are rotatably connected to one end of the rotating block 16. When the piston rod of the propulsion cylinder 13 extends or retracts, it drives the hexagonal block 15 through the connecting plate 14 to move back and forth. The side wall of the hexagonal block 15 is rotatably connected to the three rotating blocks 16. The other end of the rotating block 16 is rotatably connected to the grippers 17, and the top of the grippers 17 is rotatably fixed on the connecting plate 14, forming a four-bar linkage structure. When the hexagonal block 15 moves forward, it pushes the rotating block 16 to open the grippers 17. When it moves backward, it pulls the rotating block 16 to close the grippers 17.

[0018] The working principle of the ring-shaped magnetic core die-casting screening auxiliary device is as follows: The device is supported by a gantry frame 1, and the bottom foot cups 2 ensure overall stability. After the ring-shaped magnetic cores to be screened have been identified as good or bad, they are placed on the conveyor belt below the gantry frame 1. After the device is started, the drive motor 6 outputs power to drive the drive gear plate 7 to rotate. Because the drive gear plate 7 meshes with the rack 8 fixed on one side of the guide rod 3 on the gantry frame 1, the slider 4, which is engaged and slidably connected to the guide rod 3, drives the upper moving seat 5 to move horizontally, thereby driving the top mounting plate 9 of the moving seat 5 and subsequent components to adjust their positions horizontally. When it moves above the magnetic core to be clamped, the lifting cylinder 10 on the mounting plate 9 is activated, pushing the moving plate 12 connected to it along the four corners. The four corner positioning sleeves of the moving plate 12 are fitted onto the limiting rod 11 and slide up and down to adjust the height of the pushing cylinder 13 and the gripper 17. After the height is adapted, the pushing cylinder 13 works, and its output end pushes the hexagonal block 15 to move. The three rotating blocks 16 connected to the side wall of the hexagonal block 15 move in conjunction with it. Since the top of the gripper 17 is rotatably connected to the connecting plate 14 and is circumferentially distributed, the rotating block 16 drives the three grippers 17 to open or close, thereby clamping the annular magnetic core. After clamping the magnetic core, the lifting cylinder 10 resets and lifts the magnetic core. Then, through the cooperation of the drive motor 6, the drive gear plate 7 and the rack 8, the moving seat 5 is moved to transfer the magnetic core to the designated position. If it is a damaged product, it is picked out, completing one screening auxiliary operation.

[0019] like Figure 2As shown, in some embodiments, the rack 8 is fixedly installed on the gantry frame 1 on one side of the guide rod 3 for horizontal movement of the moving seat 5; when the drive motor 6 outputs power to drive the drive gear 7 to rotate, since the rack 8 is fixed, the meshing drive gear 7 will move linearly along the length direction of the rack 8, and thus drive the moving seat 5 to move synchronously through the fixed connection between the drive motor 6 and the moving seat 5.

[0020] like Figure 3 As shown, in some embodiments, positioning sleeves are installed at the four corners of the movable plate 12, and the positioning sleeves slide in connection with the limiting rod 11; through the sliding cooperation between the positioning sleeves and the limiting rod 11, horizontal deviation or tilting of the movable plate 12 during the lifting and lowering process can be avoided.

[0021] like Figure 4 As shown, in some embodiments, the grippers 17 are circumferentially distributed.

[0022] like Figure 4 As shown, in some embodiments, the top of the gripper 17 is rotatably connected to the connecting plate 14; The circumferentially distributed design allows the grippers 17 to apply clamping force from multiple symmetrical points on the toroidal magnetic core, avoiding uneven force distribution caused by single-point or two-point clamping, and effectively preventing the magnetic core from shifting, slipping or deforming during clamping and transportation.

[0023] like Figure 1-4 As shown, in some embodiments, the annular magnetic cores placed on the conveyor belt below the gantry frame 1 of the annular magnetic core die-casting screening auxiliary device are used to identify the quality of products and are picked up by the grippers 17.

[0024] like Figure 1-4 As shown, in some embodiments, after the annular magnetic core is die-cast, the screening auxiliary device moves to one side after being gripped by the gripper 17 to pick out the damaged products.

[0025] Since the magnetic cores on the conveyor belt have been identified as good or bad in advance, after the gripper 17 picks up the magnetic cores, the horizontal moving module can transfer the magnetic cores in different states to the corresponding areas—such as transferring damaged magnetic cores to the "non-conforming product collection area" and transferring qualified magnetic cores to the "qualified product temporary storage area," thereby realizing the core function of "screening assistance," replacing manual sorting, improving sorting efficiency and accuracy, and avoiding the problem of human confusion between qualified and damaged magnetic cores.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
