Description

Technical Field

[0002] Ferrite core is mainly composed of three metal elements: iron (Fe), manganese (Mn) and zinc (Zn). It is usually called manganese-zinc ferrite and is a high-frequency magnetic conductive material. The annular ferrite core has no air gap and the cross-sectional area is consistent, so the magnetic effect is very high. There are many specifications and sizes of ferrite rings. According to the different materials of the rings, they can be selected, and different coatings can be used to simplify the winding and increase the breakdown voltage. Ferrite core is made of dense and uniform ceramic structure non-metallic magnetic material with low coercive force, also known as soft ferrite. It is composed of iron oxide (Fe2O3) and one or more other metals (such as manganese, zinc, nickel, magnesium) oxide or carbonate compounds. The ferrite raw material is pressed, then sintered at 1300℃, and finally machined into a finished core that meets the application requirements. Compared with other types of magnetic materials, the advantages of ferrite are high magnetic permeability, high resistance and low eddy current loss in a wide frequency range.

[0027] The present invention provides a detection device for manganese-zinc ferrite cores. Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The detection equipment for manganese-zinc ferrite cores is used as an example to test the core body under low temperature conditions. The fan and the external unit cooperate with each other to blow cool air into the protective cover. The temperature sensor senses the temperature change inside the protective cover. The core body enters the protective cover and is located in a square frame. The electric push rod pushes the moving frame and the moving seat to move in the inner wall of the square frame and approach the core body. The moving frame drives the L-shaped indicator to slide in the inner wall of the square frame. The moving seat drives the anti-slip ring and the contact seat to approach the core body and push to the right rear of the square frame. The moving frame pushes the contact seat and the moving seat extrusion spring to slide in the inner wall of the moving frame. After the trigger sensor contacts the inner wall of the moving frame, the electric push rod pauses. After the working contact seat contacts the magnetic core body, the inductance detector can perform real-time inductance test on the magnetic core body under the electrical connection with the contact seat, and transmit the test data to the main controller in a unified manner. The main controller controls the CCD detection machine to check the position of the scale lines indicated by the L-shaped indicator and the indicator arrow, and then the specifications of the magnetic core body can be calculated, so that the specifications of magnetic core bodies of different specifications can be measured to see whether they meet the use requirements, and the inductance performance can be tested under low temperature. The whole magnetic core body can achieve two detection functions, and its overall performance and product specifications can be tested, which can prevent unqualified magnetic core bodies from flowing into the subsequent use process.

[0029] (2) The detection equipment for manganese-zinc ferrite cores is as follows: the core body is placed on the top wall of the unloading platform, the electric push rod five pushes the push plate two to slide on the unloading platform toward the feed port and the inner wall of the working chamber, and then enters the top wall of the lifting platform, the electric push rod three pushes the lifting platform to slide upward and drives the limit slider to slide on the inner wall of the limit slide groove, the core body is tested, the electric push rod three retracts the lifting platform to slide downward in the inner wall of the working chamber, the lifting platform drives the limit slider to slide downward in the inner wall of the limit slide groove, the lifting platform enters the inner wall of the working chamber and is flush with the top wall of the feed port, the electric push rod four pushes the push plate one out of the receiving groove, and the core body on the lifting platform is removed. The core body is pushed to the discharge port at the rear, and falls into the inner wall of the high-quality frame after passing the inclined surface of the discharge port at the rear. If the core body fails the test, the electric push rod five pushes the push plate two to push the core body on the lifting platform to the inner wall of the discharge port at the right, and falls into the inner wall of the defective frame after passing the inclined surface of the discharge port at the right. When the core body is tested, the material can be automatically loaded. After the inspection is completed, the core bodies with different inspection structures can be classified and placed, and there is no need to manually take them for repackaging. This has good convenience, reduces the workload of manual inspection, and improves the overall inspection efficiency.

[0030] (3) The detection equipment for manganese-zinc ferrite cores drives the large gear and the rotating shaft that are meshed with the small gear driven by the reduction motor to rotate. The rotating shaft drives the rotating frame, the second electric push rod, the adjustment seat and the test seat to rotate and adjust the position of the test seat. The position of the test seat matches the core body. The second electric push rod pushes the adjustment seat and the positioning rod to move downward. The adjustment seat pushes the test seat and the pressure sensor to contact the top wall of the core body and apply a force for a certain period of time. The actual pressure force is monitored by the pressure sensor. The CCD detection machine is used to check whether the core body remains intact and undamaged, so that the pressure resistance of the core body under low temperature can be tested, and the degree of understanding of the performance of the core body to be tested is improved. The entire device has a wider range of product performance measurement. BRIEF DESCRIPTION OF THE DRAWINGS

The magnetic core body 9 to be tested is placed on the top wall of the discharge table 218, and then the push plate 219 is pushed by the electric push rod 5 216 to slide on the discharge table 218, and the magnetic core body 9 to be tested is pushed to the inner wall of the feed port 215 until it enters the inner wall of the working chamber 27 and then enters the lifting platform. 28 top wall position, and then through the electric push rod three 26 to push the lifting platform 28 to slide upward in the inner wall of the working chamber 27, the lifting platform 28 drives the limit slider 214 to slide upward in the corresponding limit slide groove 210 inner wall, when the limit slider 214 slides to the top of the limit slide groove 210, the lifting platform 28 enters the lifting groove 29 inner wall and is flush with the top wall of the detection platform 1, so that the magnetic core body 9 enters the protective cover 3 and is located in the inner wall of the square frame 81, and the electric push rod one 84 pushes the moving frame 85 and the moving seat 812 to move in the inner wall of the square frame 81 and approach the magnetic core body 9, when the moving frame 85 moves, it will drive the L-shaped indicator 86 to slide in the inner wall of the square frame 81, and then the moving seat 812 drives the anti-slip ring 89 and After the contact seat 813 approaches the magnetic core body 9, it is pushed to the right rear of the square frame 81, so that the magnetic core body 9 fits against the right rear inner wall of the square frame 81, and then the moving frame 85 continues to push the contact seat 813 and the moving seat 812 to squeeze the spring 87 to slide in the inner wall of the moving frame 85, and then after the trigger sensor 88 contacts the inner wall of the moving frame 85, the electric push rod 84 stops working and maintains the contact pushing state, and the anti-slip ring 89 can increase the friction with the outer wall of the magnetic core body 9 to prevent slipping. At the same time, after the contact seat 813 contacts the magnetic core body 9, the real-time inductance test of the magnetic core body 9 can be carried out through the electrical connection between the inductance detector 83 and the contact seat 813, and the test data is uniformly transmitted and summarized to the main controller 4.The CCD detector 814 is controlled by the main controller 4 to check the position of the scale line 810 indicated by the L-shaped indicator 86 and the indicator arrow 811, so that the specifications of the magnetic core body 9 can be measured, and then the small gear 72 is driven to rotate by the reduction motor 73, and then the large gear 74 and the rotating shaft engaged with it rotate. When the rotating shaft rotates, it drives the rotating frame 75, the electric push rod 76, the adjustment seat 78 and the test seat 79 to rotate and adjust the position of the test seat 79, so that the position of the test seat 79 matches the magnetic core body 9, and the electric push rod 76, the adjustment seat 78 and the test seat 79 are rotated. 6 pushes the adjustment seat 78 and the positioning rod 77 downward, and then the adjustment seat 78 pushes the test seat 79 and the pressure sensor 710 to contact the top wall of the magnetic core body 9 and apply a force for a certain period of time, and the actual pressure force is monitored by the pressure sensor 710, and the CCD detection machine 814 is used to check whether the magnetic core body 9 is intact and not damaged. If the magnetic core body 9 passes the pressure test, the main controller 4 will control the active end of the electric push rod 3 26 to retract, and then the lifting platform 28 is in the working state. The lifting platform 28 drives the limiting slider 214 to slide downward in the inner wall of the corresponding limiting slot 210. When the limiting slider 214 slides to the bottom of the limiting slot 210, the lifting platform 28 enters the inner wall of the working chamber 27 and is flush with the top wall of the feed port 215. The electric push rod 24 pushes the push plate 1 25 out of the receiving groove 23 and enters the working chamber 27, pushing the magnetic core body 9 on the top wall of the lifting platform 28 to the discharge port 213 at the rear, and passing through the inclined surface of the discharge port 213 at the rear. After that, it falls into the inner wall of the good product frame 212. If the magnetic core body 9 fails the test, the electric push rod 5 216 will push the push plate 219 to slide in the unloading platform 218, and push the magnetic core body 9 on the lifting platform 28 to the inner wall of the discharge port 213 on the right side, and then fall into the inner wall of the defective frame 211 after passing the inclined surface of the discharge port 213 on the right side, thereby completing the classification and placement of the magnetic core bodies 9 after the test is completed, and then the above operation process can be repeated to continuously perform performance testing on the magnetic core bodies 9 to be tested.
