A transport top plate 12 is fixedly connected to the top of the two transport inner plates 5. A transport fixing strip 15 is fixedly connected to one side of the transport top plate 12. A transport fixing column 16 is fixedly connected to the inner side of one end of the transport fixing strip 15. A transport pressing strip 18 is rotatably connected to the side of the transport fixing column 16. A first torsion spring 17 is installed between the transport pressing strip 18 and the transport fixing column 16. A magnetic core 14 is slidably clamped to the top of the transport slide bar 10. A second motor 27 is fixedly connected to the top of the mounting bottom box 1. The output end of the second motor 27 is fixedly connected to a driving rotating ring 28. An upper plate connecting strip 29 is fixedly connected to the side of the driving rotating ring 28. A fixed upper plate 31 is fixedly connected to the bottom of the upper plate connecting strip 29. Two mounting clamping blocks 33 are fixedly connected to one side of the fixed upper plate 31. A feeding shaft 34 is fixedly connected to the inner side of the mounting clamping block 33. A feeding ring plate 37 is rotatably connected to the side of the feeding shaft 34.

A spring installation cylinder 36 is fixedly connected to the side of the feeding ring plate 37. A second torsion spring 35 is installed inside the spring installation cylinder 36. The second torsion spring 35 is sleeved on the side of the feeding shaft 34. Protective outer blocks 32 are fixedly connected to both sides of the fixed upper plate 31.

A lower plate ring 24 is fixedly connected to the side of the detection rotating shaft 23. A lower plate connecting strip 25 is fixedly connected to the bottom of the lower plate ring 24. A fixed lower plate 26 is fixedly connected to the top of the lower plate connecting strip 25. An upper plate rotating ring 30 is fixedly connected to the inner side of the upper plate connecting strip 29. The upper plate rotating ring 30 is rotatably connected to the side of the detection rotating shaft 23. A card slot with the same size as the magnetic core 14 is formed between the fixed lower plate 26 and the fixed upper plate 31;During use: Place the magnetic core 14 into the feeding frame 11, and it slides down between the transport slide bar 10 and the transport top plate 12 until it abuts against the transport inclined block 13. Then, the second motor 27 rotates, causing the fixed upper plate 31 to rotate towards the transport inclined block 13. When the feeding ring plate 37 touches the magnetic core 14, the feeding ring plate 37 rotates along the curved surface at one corner of the feeding ring plate 37, causing the feeding ring plate 37 to contract. After the feeding ring plate 37 passes over the magnetic core 14, it is twisted by the second torsion spring 35 to reset the feeding ring plate 37. Then, the second motor 27 rotates in reverse, causing the feeding ring plate 37 to hook the magnetic core 14. Since the other corner of the feeding ring plate 37 is a right angle and fits against the fixed upper plate 31, the feeding ring plate 37 is fixed, and the magnetic core 14 is hooked out. The transport pressing bar 18 is pushed to rotate upwards. After hooking out, the transport pressing bar 18 is twisted and reset by the first torsion spring 17 to press the next magnetic core 14. At the same time, the magnetic core 14 slides along the feeding ring plate 37 to the top of the fixed upper plate 31. At the same time, the first motor 22 is started, causing the fixed lower plate 26 to rotate and fit against the fixed upper plate 31, clamping the magnetic core 14 between the fixed lower plate 26 and the fixed upper plate 31. Then, the second motor 27 and the first motor 22 rotate synchronously to rotate the magnetic core 14 to one side for detection.;

[0025] Furthermore, both sides of the installation bottom box 1 are fixedly connected with support side plates 2. The inner top of the support side plates 2 is fixedly connected with a support top plate 3. The bottom of the support top plate 3 is fixedly connected with a detection oil cylinder 19. The bottom of the detection oil cylinder 19 is fixedly connected with a detection upper die 20. The top of the installation bottom box 1 is fixedly connected with a detection lower die 21. One side of the installation bottom box 1 is fixedly connected with a transport bottom plate 7. Both sides of the transport bottom plate 7 are fixedly connected with transport bottom blocks 6. The other side of the transport bottom blocks 6 is fixedly connected with a transport inner plate 5. The top of the transport bottom plate 7 is fixedly connected with a transport push block 8. One corner of the top of the transport push block 8 is a curved surface. The spacing of the feeding ring plate 37 is the same as the width of the transport bottom plate 7. During use: The detection upper die 20 is pushed by the detection oil cylinder 19, causing the detection upper die 20 and the detection lower die 21 to clamp the bottom and top of the fixed lower plate 26 and the fixed upper plate 31 to detect the magnetic core 14 in the middle. After completion, the fixed upper plate 31 and the fixed lower plate 26 are rotated to one side of the transport inclined block 13. Then, the fixed upper plate 31 continues to rotate, and the magnetic core 14 is pushed out by the transport push block 8, causing the magnetic core 14 to slide along the transport bottom plate 7. Then, it rotates to hook the next magnetic core 14, and so on, to quickly detect the magnetic core 14.

[0026] Working principle: When in use, the magnetic core 14 is put in through the feed frame 11, and slides between the transport slide bar 10 and the transport top plate 12 until the transport inclined block 13 is against it. Then the second motor 27 rotates to make the fixed upper plate 31 rotate toward the transport inclined block 13. When the loading ring plate 37 hits the magnetic core 14, the loading ring plate 37 rotates along the curved surface of one corner of the loading ring plate 37 to shrink the loading ring plate 37. When the loading ring plate 37 crosses the magnetic core 14, the loading ring plate 37 is reset by twisting through the second torsion spring 35. Then the second motor 27 reverses to make the loading ring plate 37 hook the magnetic core 14. Because the other corner of the loading ring plate 37 is at a right angle and fits the fixed upper plate 31, the loading ring plate 37 is fixed, the magnetic core 14 is hooked out, and the transport pressure strip 18 is pushed to rotate upward. After being hooked out, the transport pressure strip 18 is reset by twisting through the first torsion spring 17 to press the next magnetic core 1 4. At the same time, the magnetic core 14 slides along the feeding ring plate 37 to the top of the fixed upper plate 31, and the first motor 22 is started to rotate the fixed lower plate 26 to fit the fixed upper plate 31, so that the magnetic core 14 is clamped between the fixed lower plate 26 and the fixed upper plate 31. Then the second motor 27 and the first motor 22 rotate synchronously to rotate the magnetic core 14 to one side for detection, and the detection upper mold 20 is pushed by the detection cylinder 19 to clamp the detection upper mold 20 and the detection lower mold 21 at the bottom and top of the fixed lower plate 26 and the fixed upper plate 31 to detect the magnetic core 14 in the middle. After completion, the fixed upper plate 31 and the fixed lower plate 26 are rotated to one side of the transport inclined block 13, and then the fixed upper plate 31 continues to rotate, and the magnetic core 14 is pushed out by the transport push block 8, so that the magnetic core 14 slides along the transport bottom plate 7, and then rotates to hook the next magnetic core 14, and this is repeated to quickly detect the magnetic core 14.
