Description

Technical Field

[0001] This utility model relates to the field of classification device technology, specifically to an integrated device for screening and classifying ring-shaped magnetic cores. Background Technology

[0002] Against the backdrop of the rapid development of the electronics and information industry, toroidal magnetic cores, as a key component of core electronic components such as transformers, inductors, and sensors, directly determine the electrical performance and service life of downstream products due to their quality consistency (such as appearance integrity, dimensional accuracy, and compliance of front and back processes). Currently, the market demand for toroidal magnetic cores is growing on a large scale, especially in fields such as new energy and 5G communications, where the requirements for magnetic core screening efficiency and accuracy are further increasing, and traditional screening and classification methods are no longer adequate to meet the needs of industrial upgrading.

[0003] Traditional toroidal magnetic core sorting and classification processes have significant shortcomings: Firstly, relying on manual sorting in conjunction with a single testing device requires manual placement of each core on the testing platform, followed by manual sorting into different bins. This is not only inefficient but also prone to missed or incorrect inspections due to human fatigue. Secondly, when manually flipping the cores to inspect both sides, it is difficult to ensure consistent orientation, leading to the omission of surface scratches, missing corners, and other defects. Furthermore, manual contact can cause secondary contamination of the cores, affecting product quality stability. In addition, the single testing device requires frequent parameter adjustments to adapt to different core specifications, resulting in a cumbersome switching process and further reducing overall production efficiency.

[0004] With the deep application of automation technology in manufacturing, the industry urgently needs an integrated device to solve the pain points of high reliance on manual labor, low efficiency, and poor precision in traditional processes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an integrated device for screening and classifying toroidal magnetic cores, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An integrated screening and sorting device for ring-shaped magnetic cores includes a support frame with feet at the bottom and a frame fixedly mounted on the top. Two rotating rollers are rotatably mounted on the frame, and belts are driven to the rollers. One of the rollers is connected to a reducer on one side of the frame, with one end of the reducer connected to the output of a servo motor. Mounting brackets are fixedly connected to both sides of the frame, and guide plates on both sides are positioned on the mounting brackets by bolts. A flip-up structure is bolted to the side wall of one of the guide plates. An industrial camera is mounted on the mounting plate, and a positioning plate is fixedly connected to the rear side wall of the frame. A cylinder is mounted on the positioning plate, and a push plate is fixedly connected to the output end of the cylinder.

[0007] Furthermore, a support plate is installed inside the frame, and the belt slides on the support plate to prevent deformation and bending.

[0008] Furthermore, the flipping structure includes an outer frame bolted to the guide plate, a plurality of rotating shafts being rotatably connected to the outer frame, and a bonding plate being fixedly connected to a bottom of the outer frame.

[0009] Furthermore, the flipping structure is inclined for flipping the annular magnetic core.

[0010] Furthermore, the bonding plate is bonded to the belt.

[0011] Furthermore, there are two industrial cameras, one at the front end and one at the rear end, used to detect the front and back sides of the toroidal magnetic core.

[0012] Furthermore, the pusher plate is horizontal to the belt and is used to push away defective products.

[0013] Compared with the prior art, this utility model provides an integrated device for screening and classifying toroidal magnetic cores, which has the following advantages: This invention achieves stable conveying through the linkage of a servo motor, reducer, and belt, with a support plate to prevent belt deformation. The magnetic core's posture is precisely adjusted by a guide plate and an inclined flipping structure. Front and back side inspections are completed by industrial cameras at both ends. Defective products are separated by a cylinder-driven horizontal push plate. The entire process requires no manual intervention, which improves screening efficiency, avoids manual omissions and errors, and prevents secondary contamination of the magnetic core. It also ensures consistent testing accuracy and product quality, adapts to the needs of large-scale production, and provides stable and qualified toroidal magnetic cores for downstream electronic component manufacturing.

[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 an integrated screening and sorting device for ring magnetic cores, including a support 1. The bottom of the support 1 is provided with a foot cup 2, and a frame 3 is fixedly mounted on the top of the support 1. Two rotating rollers 4 are rotatably mounted on the frame 3, and a belt 5 is drivingly connected to each of the rotating rollers 4. One of the rotating rollers 4 is connected to a reducer 6 on one side of the frame 3, and one end of the reducer 6 is connected to the output end of a servo motor 7. The servo motor 7 and the reducer 6 work together to ensure that the conveying speed of the belt 5 is stable and controllable, and the bearing plate helps to prevent the belt 5 from deforming and bending, ensuring that the magnetic core does not deviate during the conveying process, thus providing a stable foundation for subsequent inspection and flipping. Mounting brackets 8 are fixedly connected to both sides of the frame 3. The mounting brackets 8 are bolted to guide plates 9 on both sides. A flipping structure 10 is bolted to the side wall of one of the guide plates 9. A mounting plate 11 is fixedly connected to the side wall of the frame 3. An industrial camera 12 is mounted on the mounting plate 11. The linkage between the guide plate 9 and the belt 5 prevents the magnetic core from shifting during transport. Furthermore, the cooperation between the flipping structure 10 and the belt 5 ensures that the front and back of the magnetic core are in a uniform posture, ensuring that the industrial camera 12 can completely capture both sides of the magnetic core and avoid missed detections due to posture confusion. A positioning plate 13 is fixedly connected to the rear end side wall of the frame 3, a cylinder 14 is installed on the positioning plate 13, and a push plate 15 is fixedly connected to the output end of the cylinder 14. After the industrial camera 12 transmits the detection results to the control system, if it is determined to be unqualified, when the magnetic core is conveyed to the end of the frame 3 by the belt 5, the cylinder 14 fixed on the positioning plate 13 is immediately activated, driving the push plate 15 to push it out horizontally, pushing the unqualified magnetic core off the belt 5; if it is qualified, the push plate 15 remains stationary, and the magnetic core flows out from the outlet with the belt 5.

[0018] The working principle of the integrated screening and sorting device for annular magnetic cores is as follows: The device is fed from the inlet by a vibratory feeder and a linear feeder. After startup, the servo motor 7 drives the rotating roller 4 through the reducer 6, which in turn drives the belt 5 on the frame 3 to transport the annular magnetic cores. During transport, the guide plates 9 on the mounting brackets 8 on both sides of the frame 3 guide the magnetic cores to maintain a stable posture. If the magnetic core needs to be flipped, the flipping structure 10 on the side wall of the guide plate 9 rotates and propels the core through the rotating shaft 102, achieving the flipping of the magnetic core at a height. Subsequently, two industrial cameras 12 on the mounting plate 11 on the side wall of the frame 3 detect whether the front and back of the magnetic core are qualified. When the magnetic core is transported to the end of the frame 3, if it is detected as a defective product, the cylinder 14 on the positioning plate 13 drives the push plate 15 to push the defective magnetic core away from the belt 5, completing the screening and sorting. Throughout the process, the foot cups 2 at the bottom of the support 1 ensure the stability of the device.

[0019] like Figure 1 As shown, in some embodiments, a support plate is installed inside the frame 3, and the belt 5 slides on the support plate to prevent deformation and bending; when the annular magnetic core is conveyed on the belt 5, it will exert downward pressure on the belt 5, especially when the device runs for a long time or conveys a large magnetic core, which can easily cause the middle area of ​​the belt 5 to sag and deform.

[0020] like Figure 3 As shown, in some embodiments, the flipping structure 10 includes an outer frame 101 bolted to the guide plate 9, a plurality of rotating shafts 102 rotatably connected in the outer frame 101, and a bonding plate 103 fixedly connected to the bottom of the outer frame 101; the annular magnetic core enters through the bonding plate 103, then the rotating shafts 102 rotate, and finally it is pushed by the belt 5, and then falls onto the belt 5 for flipping.

[0021] like Figure 3 As shown, in some embodiments, the flipping structure 10 is inclined for flipping the annular magnetic core.

[0022] like Figure 3 As shown, in some embodiments, the bonding plate 103 is bonded to the belt 5; The bonding design of the bonding plate 103 and the belt 5, and the rolling friction design of the rotating shaft 102, not only prevent the magnetic core from shifting or falling during the flipping process, but also reduce damage to the surface of the magnetic core, ensuring that the magnetic core can still be stably conveyed along the belt 5 after flipping, providing a good posture basis for subsequent inspection and sorting.

[0023] like Figure 4 As shown, in some embodiments, there are two industrial cameras 12, one at the front end and one at the rear end, used to detect the front and back sides of the toroidal magnetic core; the industrial camera 12 can be a DMK33UX273 camera; the transmission computer performs system identification and judgment.

[0024] like Figure 4 As shown, in some embodiments, the push plate 15 is horizontal to the belt 5 and is used to push away defective products. Since the push plate 15 is horizontal to the belt 5 and the installation position corresponds to the conveying path of the belt 5 at the tail end of the frame 3, when the defective magnetic core is conveyed to the front of the push plate 15 with the belt 5, the push plate 15 can push the magnetic core off the belt 5 in the horizontal direction under the drive of the cylinder 14.

[0025] 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.
