Description

Technical Field

[0001] This utility model relates to the field of soft magnetic cores, specifically a low-loss, high-frequency soft magnetic core detection and screening device. Background Technology

[0002] As a type of magnetic material with important applications in the electronics field, the performance of soft magnetic cores directly affects the overall efficiency of electronic devices. Soft magnetic cores are magnetic materials that can be easily magnetized and generate a large magnetic induction intensity under a weak magnetic field, and whose magnetism can be quickly lost after the magnetic field is removed. They have characteristics such as high permeability, low coercivity, and low hysteresis loss, and are widely used in electronic components such as transformers, inductors, and filters. They are key components for realizing electromagnetic energy conversion and transmission.

[0003] Before magnetizing a soft magnetic core, its appearance must be carefully inspected to check for defects such as cracks, pores, and sand holes. These appearance defects may cause stress concentration during magnetization, which may affect the magnetic properties of the core or even damage it. Secondly, the dimensional accuracy of the soft magnetic core must be accurately measured, because dimensional deviations will change the inductance, magnetic flux, and other parameters of the electromagnetic component, making it impossible for the component to meet the performance requirements of the design.

[0004] Currently, manufacturers generally use scanning inspection technology to scan the surface of soft magnetic cores to obtain their precise size and shape data. Although this inspection equipment is efficient in detecting data, unqualified magnetic cores need to be manually screened, which reduces the efficiency of the entire production process of soft magnetic cores. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a low-loss, high-frequency soft magnetic core testing and screening device to solve the technical problem that personnel are required to remove substandard magnetic cores during the testing process of soft magnetic core testing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-loss, high-frequency soft magnetic core detection and screening device, comprising a screening device, a control panel installed on the outer wall of the screening device, a feed pipe fixed at one end of the screening device, a first pipe opened at the bottom of the feed pipe, a detection chamber arranged inside the screening device, an operating table installed at the bottom of the detection chamber, a pneumatic controller fixed on the inner wall of the detection chamber, a high-pressure air pipe connected to the top of the pneumatic controller, a pneumatic source device installed on the top of the screening device, a detection device arranged on the top of the detection chamber, a third pipe opened on one side of the detection device, a second discharge chamber connected to the end of the third pipe, and a second pipe opened inside the screening device, the end of the second pipe connected to the first discharge chamber.

[0007] By adopting the above technical solution, the operating table uniformly conveys the magnetic core to the bottom of the testing equipment. The testing camera at the bottom of the testing equipment takes pictures of the magnetic core. Then, the testing equipment analyzes and compares the captured data of the magnetic core's appearance with the data of a qualified magnetic core. If the magnetic core is unqualified, the air pressure source device delivers high-pressure gas to the air pressure controller through a high-pressure air pipe. The air pressure controller controls the amount of high-pressure gas ejected, so that the high-pressure gas ejected from the nozzle on one side of the air pressure controller can blow the unqualified magnetic core into the third pipe. The unqualified magnetic core falls into the second discharge hopper through the third pipe.

[0008] The present invention is further configured such that a first conveyor belt is provided at the end of the first pipe, and a first motor is installed at the end of the first conveyor belt.

[0009] By adopting the above technical solution, the magnetic core to be tested enters the first pipe through the feed pipe, and the magnetic core falls down the first conveyor belt along the first pipe. The first motor drives the first conveyor belt to operate, and the first conveyor belt transports the magnetic core to the surface of the operating table.

[0010] The present invention is further configured such that a rotating rod is fixed at the bottom of the operating table, and a second motor is connected to the end of the rotating rod.

[0011] By adopting the above technical solution, the operator can adjust the rotation speed of the control panel through the control panel, and the second motor drives the control panel to rotate through the rotating rod.

[0012] The present invention is further configured such that a guide plate is fixed to the inner wall of the screening device, and the bottom of the guide plate does not contact the upper surface of the operating table.

[0013] By adopting the above technical solution, when the tested magnetic core is transported to the port of the second pipe by the operating table, the guide plate guides the magnetic core into the interior of the second pipe.

[0014] The present invention is further provided that the outer wall of the screening device is provided with an observation window, and the observation window is made of tempered glass.

[0015] By adopting the above technical solution, personnel can clearly observe the magnetic core testing inside the testing chamber through the observation window.

[0016] The present invention is further configured such that a detection camera is provided at the bottom of the detection device, and a lighting lamp is installed at the bottom of the detection device.

[0017] By adopting the above technical solution, the illumination lamp shines on the magnetic core, providing sufficient light intensity for the detection camera to capture clear images.

[0018] The present invention is further configured such that a second conveyor belt is installed at the end of the second pipe, and a third motor is connected to the end of the second conveyor belt.

[0019] By adopting the above technical solution, the third motor drives the second conveyor belt to operate, and the second conveyor belt transports the tested magnetic core into the second pipeline.

[0020] The present invention is further configured such that a first collection box and a second collection box are respectively installed inside the first discharge bin and the second discharge bin.

[0021] By adopting the above technical solution, the unqualified magnetic cores fall into the second discharge hopper through the third pipe. The second discharge hopper contains a second collection box, which collects and stores the unqualified magnetic cores. The qualified magnetic cores fall into the first discharge hopper through the second pipe. The first discharge hopper contains a first collection box, which collects and stores the qualified magnetic cores.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention incorporates a screening device, a feeding pipe, an operating table, a first discharge bin, a guide plate, a testing device, and a pneumatic pressure source device. The operating table uniformly transports the magnetic cores to the bottom of the testing device. A camera at the bottom of the testing device captures images of the magnetic cores. The testing device then analyzes and compares the captured data of the magnetic core's surface with the data of a qualified magnetic core. If the magnetic core is unqualified, the pneumatic pressure source device delivers high-pressure gas to a pneumatic pressure controller via a high-pressure gas pipe. The pneumatic pressure controller controls the amount of high-pressure gas ejected, ensuring that the high-pressure gas ejected from a nozzle on one side of the pneumatic pressure controller blows the unqualified magnetic cores into a third pipe. The unqualified magnetic cores then fall into the second discharge bin through the third pipe.

[0024] This invention incorporates a pressure source device, a high-pressure air pipe, a pressure controller, and a nozzle. The pressure source device delivers high-pressure gas to the pressure controller via the high-pressure air pipe. The pressure controller controls the amount of high-pressure gas ejected. The nozzle ejects gas at a certain pressure to push the defective magnetic core to move. Compared to traditional mechanical pushing, this jet-driven pushing method has a faster pushing speed and less wear on the equipment. Attached Figure Description

Then, the testing device 7 analyzes and compares the captured data of the magnetic core's appearance with the data of a qualified magnetic core. If the magnetic core is unqualified, the air... The pressure source device 6 delivers high-pressure gas to the pressure controller 602 via the high-pressure gas pipe 601.
