[0002] Soft ferrite core is a high-frequency magnetic material. Its principle is the same as that of silicon steel sheet, but it is used in high-frequency environment. It is mainly used for high-frequency transformers, such as switching power supplies, line output transformers, high-frequency magnetic rings, anti-interference, etc., to increase magnetic permeability. As an important component of electronic components, the stability and reliability of the performance of soft ferrite cores have a direct impact on the working effect of electronic equipment. Therefore, in the production process, in order to ensure the quality of its products, it is necessary to use soft ferrite core detection equipment to detect them;
[0003] The problem of this soft ferrite core detection device is that when the workpiece is detected by moving the detection component, it is not convenient to locate the upper and lower corresponding positions between the inspection block and the workpiece when the detection component is moving, which may cause the detection component to deviate from the upper and lower corresponding positions of the workpiece when moving. Patent No. CN219656916U in the prior art is a soft ferrite core detection device. When in use, the staff inserts the clamp seat into the corresponding fixed groove, starts the first cylinder, drives the corresponding telescopic rod to extend, so that the corresponding telescopic rod passes through the through groove and extends to the inside of the corresponding groove. There are three clamp seats to fix three workpieces. After a workpiece is detected by the detection block, the positioning table is pushed to move the positioning table in the moving groove, so that the clamp seat at the rear follows the synchronous movement, and the corresponding telescopic rod moves in the corresponding groove, thereby solving the above problem.
[0004] However, when using this type of soft ferrite core detection device to fix workpieces of different shapes, it is necessary to replace the corresponding clamping head according to the shape of the workpiece, and the adaptability of the equipment is low; therefore, it does not meet the existing needs. In this regard, we propose a soft ferrite core detection device. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The utility model places the soft ferrite core in the middle of the upper end face of the fixture seat when the device is needed, and then uses a stepper motor to synchronously drive multiple fixed heads located on both sides of the upper side of the fixture seat to move inward at the same time. If the soft ferrite core is circular as a whole, the fixed head closest to the middle position of the front and rear end faces of the circular soft ferrite core will contact the soft ferrite core before the fixed heads at other positions. When a fixed head has already contacted the soft ferrite core, but the fixed head is still moving, the fixed head in contact with it will stay in place and will not move further. In the process, the fixing spring will be squeezed, and the fixed head that is not in contact with the soft ferrite core will continue to move until it contacts other parts of the soft ferrite core to fix it. Through the above technical solution, soft ferrite cores of various shapes can be automatically fixed, so that when soft ferrite cores of different shapes need to be fixed, it is no longer necessary to install corresponding clamping heads, thereby improving the convenience of the device.
[0016] 2. The utility model can improve the friction between the fixing head and the soft ferrite core by means of the anti-skid stripes on the outer surface of the fixing head, thereby preventing the soft ferrite core from slipping during the process. BRIEF DESCRIPTION OF THE DRAWINGS

A synchronous shaft 16 is provided on both sides above the transmission shaft 18, and the transmission shaft 18 and the synchronous shaft 16 are connected in series through a synchronous chain 19; when this device needs to be used, the soft ferrite core is placed in the middle position of the upper end surface of the fixture seat 3, and then the stepper motor 17 is started. The stepper motor 17 can drive the transmission shaft 18 connected thereto and the synchronous shaft 16 connected in series with the transmission shaft 18 through the synchronous chain 19 to rotate synchronously.
[0026] A square transmission rod 15 is fixedly provided on one side of the outer surface of the synchronous shaft 16, and a threaded column 12 is provided on one side of the synchronous shaft 16.

[0027] The surface of the threaded column 12 facing the cylindrical groove 6 is connected to the cylindrical groove 6 through a roller bearing, and an internal threaded through hole 13 located on the outer surface of the strip plate 4 is provided on the outer side of the threaded column 12, and the external thread of the threaded column 12 matches the internal thread of the internal threaded through hole 13; a guide rod 11 fixed to the outer surface of the metal strip 5 is provided on both sides of the threaded column 12, and the guide rod 11 is laterally movable and penetrates the strip plate 4; through the internal thread transmission of the internal threaded through hole 13, the rotating threaded column 12 can move forward and backward while rotating, and the metal strip 5 connected to the threaded column 12 will also pass through it during the movement, and through the guide rod 11 fixed to the outer surface of the metal strip 5, the metal strip 5 will only move with the threaded column 12, and will not rotate with the rotation of the threaded column 12, and the fixed head 8 located on the outer side of the metal strip 5 will move together with it during the movement;

When the fixed heads 8 on both sides above the clamp seat 3 fit each other, the stepper motor 17 is turned off. At this time, the soft ferrite core is fixed. Through the above technical solution, soft ferrite cores of various shapes can be automatically fixed, so that when it is necessary to fix soft ferrite cores of different shapes, it is no longer necessary to install the corresponding clamping head, thereby improving the convenience of the equipment.
[0029] When the soft ferrite core is fixed, it is moved to its position by the positioning table 2 and tested by the testing table 1. When the test is completed, the stepping motor 17 drives the transmission shaft 18 connected thereto to rotate in the reverse direction, so that the fixing head 8 can be moved back to its original position, thereby contacting the fixing of the soft ferrite core.
