Description

Technical Field

[0001] This utility model relates to the field of magnetic ring detection technology, specifically to an automatic quality detection and sorting device for magnetic rings. Background Technology

[0002] Magnetic rings are commonly used anti-interference components in electronic circuits, effectively suppressing high-frequency noise. They are typically made of ferrite materials. Magnetic rings exhibit different impedance characteristics at different frequencies; generally, their impedance is very small at low frequencies, but increases sharply as the signal frequency rises. Even when produced in the same batch, magnetic rings may appear almost identical, but their magnetic field strength can vary due to various external interferences encountered during production. Therefore, all magnetic rings require testing after production to ensure quality. Current testing is done manually, but due to the large number and small size of the rings, manual testing is inefficient, prone to errors, and reduces production efficiency.

[0003] Utility model patent CN215784996U discloses a magnetic ring screening device. This device includes a conveyor belt on a base plate, side baffles fixed on both sides of the conveyor belt, magnetic rings arranged sequentially on the conveyor belt, a drive motor fixed to the side end of a support, and the output shaft of the drive motor fixedly connected to the drive roller of the conveyor belt. An outlet is provided on the side baffle, and a pushing mechanism is provided at the side end of the outlet. A detection mechanism and a controller are provided on the base plate. This device uses the detection mechanism to detect the magnetic rings and the pushing mechanism to remove unqualified magnetic rings, achieving automatic screening of magnetic rings, increasing screening speed, and improving production efficiency. A secondary inspection of the magnetic rings is performed by another detection mechanism and an alarm light, which not only increases screening quality but also allows for self-diagnosis of equipment malfunctions, reducing losses caused by equipment failures.

[0004] While the aforementioned utility model can screen and remove defective magnetic rings, it relies on a motor and a moving rod to directly eject the defective rings. However, if the friction between the magnetic ring and the conveyor belt surface is high, the ring may bounce a distance when ejected by the moving rod, making it difficult to collect. Therefore, we propose an automatic magnetic ring quality inspection and sorting device. Utility Model Content

[0005] This invention provides an automatic quality inspection and sorting device for magnetic rings to solve the problems mentioned in the background art.

[0008] The sorting mechanism includes a support plate, a control box disposed on the lower front side of the support plate, a cylinder disposed on the upper front side of the support plate, and a clamping mechanism installed on the upper rear side of the support plate.

[0010] As a preferred technical solution, limit plates are provided on both the front and rear sides of the upper surface of the detection conveyor belt, a magnetic ring is placed between the limit plates, and a notch is opened on the left side of the upper surface of the limit plate.

[0011] As a preferred technical solution, the cylinder telescopic rod is positioned facing the support plate and passing through the support plate, and the extended end of the cylinder is fixedly connected to the front surface of the clamping mechanism.

[0013] As a preferred technical solution, the outer surface of the threaded rod is provided with threads at both ends, and the two threads are of equal length and opposite direction.

[0014] As a preferred technical solution, rubber pads are attached to the surfaces between the two clamping plates, and the distance between the clamping plates is greater than the diameter of the magnetic ring.

[0015] As a preferred technical solution, the size of the notch is the same as the size of the clamping plate, and the extension length of the cylinder is equal to the distance between the center line of the upper surface of the detection conveyor belt and the sorting conveyor belt.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By using a clamping method to remove the defective magnetic ring from the inspection conveyor belt, it is possible to prevent the magnetic ring from being too difficult to separate due to excessive friction between it and the inspection conveyor belt.

[0018] 2. Once a magnetic ring is detected as defective, it can be quickly removed and graded to prevent a long interval between detection and removal, which could lead to the removal of incorrect magnetic rings. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-4 This embodiment provides a technical solution:

[0027] An automatic quality inspection and sorting device for magnetic rings includes an operating table 1. A detection conveyor belt 5 is arranged at the middle position of the upper surface of the operating table 1. A sorting conveyor belt 4 is arranged behind the detection conveyor belt 5. A detection mechanism 2 is arranged at the left front end of the detection conveyor belt 5. A sorting mechanism 3 is arranged on the left front side of the detection conveyor belt 5. The sorting mechanism 3 includes a support plate 31, a control box 32 arranged at the lower front end of the support plate 31, a cylinder 33 arranged at the upper front end of the support plate 31, and a clamping mechanism 34 installed at the upper rear end of the support plate 31. Through the above mechanism, unqualified magnetic rings 51 can be easily removed from the detection conveyor belt 5 for sorting.

[0028] Furthermore, the clamping mechanism 34 includes a clamping housing 341 and a threaded rod 342 rotatably connected inside the clamping housing 341. A motor 343 is provided on the right side surface of the clamping housing 341. Connecting plates 344 are provided on both the left and right sides of the threaded rod 342. Clamping plates 345 are welded to the ends of the connecting plates 344. The magnetic ring 51 can be clamped by the cooperation of the clamping plates 345.

[0029] Furthermore, limit plates 52 are provided on both the front and rear sides of the upper surface of the inspection conveyor belt 5, and a magnetic ring 51 is placed between the limit plates 52. A notch 53 is opened on the left side of the upper surface of the limit plate 52 for the clamping plate 345 to be placed.

[0030] In this embodiment, the telescopic rod of the cylinder 33 is positioned toward and through the support plate 31, and the extended end of the cylinder 33 is fixedly connected to the front surface of the clamping mechanism 34, thereby controlling the horizontal movement of the clamping mechanism 34.

[0031] In this embodiment, the output shaft of the motor 343 is coaxially connected to the threaded rod 342, and the cross-section of the connecting plate 344 is an L-shaped mechanism. The motor 343 can control the rotation of the threaded rod 342.

[0032] In this embodiment, threads are provided at both ends of the outer surface of the threaded rod 342. The two threads are of equal length and opposite direction. When the threaded rod 342 rotates, the connecting plates 344 on both sides can move in different directions.

[0033] In this embodiment, rubber pads are attached to the surfaces between the two clamping plates 345, and the distance between the clamping plates 345 is greater than the diameter of the magnetic ring 51, which increases the friction between the clamping plates 345 and the magnetic ring 51.

[0034] In this embodiment, the size of the notch 53 is the same as the size of the clamping plate 345, and the extension length of the cylinder 33 is equal to the distance between the center line of the upper surface of the detection conveyor belt 5 and the sorting conveyor belt 4, ensuring that the cylinder 33 can transport the defective magnetic ring 51 from the detection conveyor belt 5 to the sorting conveyor belt 4.

[0035] It is worth noting that the structure and working principle of the cylinder 33 and motor 343 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here. The structure and working principle of the detection mechanism 2, detection conveyor belt 5, magnetic ring 51 and limiting plate 52 involved in this embodiment are all technologies disclosed in the prior art, and will not be described in detail here.

[0036] In the specific use of the automatic magnetic ring quality detection and sorting equipment of this embodiment, when the detection mechanism 2 detects a defective magnetic ring 51, it sends a signal to the control box 32. After receiving the signal, the control box 32 is in a ready state. When the detection mechanism 2 starts to detect the next magnetic ring 51, the defective magnetic ring 51 has just moved between the clamping plates 345. At this time, the detection mechanism 2 sends a signal to the control box 32 again. After receiving the signal, the control box 32 starts the motor 343, and controls the two connecting plates 344 to move in the opposite direction through the rotation of the threaded rod 342, so that the clamping plates 345 can move closer to each other to clamp and fix the defective magnetic ring 51. Then, the cylinder 33 is started and extended to move the defective magnetic ring 51 onto the sorting conveyor belt 4. Then, the motor 343 is started in reverse so that the clamping plates 345 release the defective magnetic ring 51, and the defective magnetic ring 51 can fall onto the upper side of the sorting conveyor belt 4. Then, the cylinder 33 is retracted and closed so that the clamping plates 345 return to the notch 53.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
