[0023] When the detection is used to carry out on-off detection to magnetic core, feeding mechanism 2 is used to orderly feed magnetic core to conveying line 3, conveying line 3 is used to deliver magnetic core to detection site, and the magnetic core is clamped and moved upwards by the work of clamping mechanism 4, so that the magnetic core is moved to the top of conveying line 3, then point touch detection mechanism 5 works, and the two sides of the magnetic core are touched, to realize detection circuit connection, and the electrical detection of magnetic core is realized by the work of clamping mechanism 4, the cooperation of feeding mechanism 2, conveying line 3, clamping mechanism 4 and point touch detection mechanism 5 can replace traditional manual operation, realize the automatic on-off detection of magnetic core, save time and effort, and the detection efficiency is high, and compared with manual detection operation, the detection accuracy is high by setting accurate operation parameters and electrically cooperating mechanical detection operation.

[0024] Specifically, feeding mechanism 2 includes side seat 21, vibrating sieve disc 22 and guide chute 23, side seat 21 is fixed on the side portion of detection table 1, vibrating sieve disc 22 is arranged above side seat 21, guide chute 23 is arranged at the discharge port of vibrating sieve disc 22 and connected with the upstream side of conveying line 3, the magnetic core is concentrated and placed in vibrating sieve disc 22, and the magnetic core is orderly fed to guide chute 23 by the work of vibrating sieve disc 22, and then delivered to conveying line 3 through guide chute 23, to realize the feeding supply of magnetic core.

[0025] Specifically, the clamping mechanism 4 includes an L-shaped frame 41, a first air cylinder 42, a mounting seat 43, a pair of second air cylinders 44 and a pair of clamping blocks 45. The L-shaped frame 41 is fixed on the top of the detection table 1 in an inverted L shape. The first air cylinder 42 is vertically fixed on the lower surface of the cantilever 411 at the top of the L-shaped frame 41. The mounting seat 43 is fixed on the end of the telescopic rod of the first air cylinder 42. The two second air cylinders 44 are symmetrically arranged on the lower surface of the mounting seat 43 and extend along the length direction of the detection table 1. The end of the telescopic rod of each second air cylinder 44 is close to each other and is provided with a clamping block 45. When the conveying line 3 transfers the magnetic core to the detection position, the first air cylinder 42 is elongated to drive the second air cylinders 44 and the clamping blocks 45 on both sides to move downward to the two sides of the magnetic core at the feeding position. The second air cylinders 44 are elongated to drive the clamping blocks 45 to move close to each other to clamp the magnetic core. Then, the first air cylinder 42 is retracted to drive the mounting seat 43 to move upward, thereby driving the magnetic core to move upward away from the conveying line 3, facilitating subsequent detection.

[0026] Specifically, the point touch detection mechanism 5 includes a pair of arched frames 51, a pair of third air cylinders 52, a pair of contact heads 53 and an electrical detection device 54. The two arched frames 51 are respectively fixed on the detection table 1 and symmetrically distributed on the two sides of the mounting seat 43. The two third air cylinders 52 are respectively fixed on the arched frames 51 and extend along the width direction of the detection table 1. The end of the telescopic rod of each third air cylinder 52 is provided with a contact head 53. The electrical detection device 54 is arranged above the detection table 1 and on one side of the L-shaped frame 41. The two contact heads 53 are electrically connected with the electrical detection device 54 through wires. When the clamped and upwardly transferred magnetic core moves to the same height as the two contact heads 53, the third air cylinders 52 are elongated to drive the contact heads 53 to move close to the two sides of the magnetic core until they are in contact, thereby realizing the connection of the detection circuit.

If the displayed resistance value is close to zero, it indicates that the conduction performance of the magnetic core is good, which is a good product. If the resistance value is very large and close to infinity, it indicates that the magnetic core has a broken circuit problem, which is a defective product, thereby realizing the on-off detection of the magnetic core.

The third conveying belt 33 is arranged on the driving mechanism 6 and is driven by the driving mechanism 6 to rotate. The fourth conveying belt 34 is arranged on the detection table 1 and located at one side of the driving mechanism 6. The fourth conveying belt 34 extends along the width direction of the detection table 1. An inclined downward discharge groove 35 is arranged at the side of the detection table 1 and connected to the downstream side of the fourth conveying belt 34. During detection, the driving mechanism 6 drives the third conveying belt 33 to rotate to be parallel to the first conveying belt 31. At this time, the upstream side of the third conveying belt 33 is connected to the downstream side of the first conveying belt 31, and the downstream side of the third conveying belt 33 is connected to the upstream side of the second conveying belt 32. The magnetic cores are transferred to the third conveying belt 33 from the first conveying belt 31, and then are transferred to the detection position. After the detection is completed and the magnetic cores are determined to be good products, the driving mechanism 6 is not worked. At this time, the magnetic cores are transferred to the second conveying belt 32 from the third conveying belt 33, and then are transferred to the subsequent packaging process from the second conveying belt 32. After the detection is completed and the magnetic cores are determined to be bad products, the driving mechanism 6 is worked to drive the third conveying belt 33 to rotate by 90 degrees, so that the downstream side of the third conveying belt 33 is connected to the upstream side of the fourth conveying belt 34. The bad magnetic cores are transferred to the fourth conveying belt 34 from the third conveying belt 33, and then are transferred to the discharge groove 35 from the fourth conveying belt 34. A material collecting vehicle is arranged below the discharge groove 35 at the side of the detection table 1, so that the bad products can be transferred to the material collecting vehicle to realize the selection of good products from the magnetic cores.

A controller 55 is arranged above the detection table 1 at one side of the electrical detection device 54 and is electrically connected to the electrical detection device 54 and the driving motor 62, respectively. The processor in the electrical detection device 54 is used to analyze whether the resistance value of the magnetic core during detection meets the requirements, so as to determine whether the magnetic core is a good product or a bad product. When the magnetic core is detected to be a bad product, a signal is sent to the controller 55 to control the driving motor 62 to work to drive the third conveying belt 33 to be connected to the fourth conveying belt 34. The fourth conveying belt 34 is used to transfer the bad magnetic cores to the discharge groove 35, so that the bad magnetic cores can be separated to improve the quality of the finished magnetic cores.
