DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-5As shown in the figure, the utility model provides a surface defect detection device, which includes a workbench 1 and a second conveyor 3 fixedly arranged at the top end inside the workbench 1. A first conveyor 2 is arranged on one side of the workbench 1, and the first conveyor 2 and the second conveyor 3 are used for conveying precision ferromagnetic components. A U-shaped clamping rod 6 is fixedly arranged on the front side of the workbench 1. A collection box 7 is slidably clamped on the U-shaped clamping rod 6, and the collection box 7 is arranged on the front side of the opening, which is convenient for centrally collecting the precision ferromagnetic components with surface defects. Support plates 9 are fixedly arranged at the bottoms of the workbench 1 and the first conveyor 2 respectively. Two reinforcing rods 10 distributed front and back are fixedly arranged between the two support plates 9, which is convenient for strengthening the supporting force of the two support plates 9.

[0027] As Figures 1-3 shown in FIGS. 5, a detection assembly 4 is fixedly arranged between the workbench 1 and the first conveyor 2 for detecting surface defects of precision ferromagnetic components. The detection assembly 4 includes a U-shaped connecting frame 41. The U-shaped connecting frame 41 is fixedly arranged between the workbench 1 and the first conveyor 2. A support table 42 is fixedly arranged at the top end inside the U-shaped connecting frame 41. A guide table 43 is fixedly arranged at the top of the support table 42. One end of the guide table 43 is arranged at one side of the bottom of the first conveyor 2, and the other end of the guide table 43 is arranged at the top of one side of the second conveyor 3, which is convenient for the precision ferromagnetic components on the first conveyor 2 to slide onto the top of the second conveyor 3 through the guide table 43 for conveying. First connecting rods 44 are fixedly arranged on the front and back sides of the top of the U-shaped connecting frame 41 respectively. The same first top plate 45 is fixedly arranged between the tops of the two first connecting rods 44. A magnetic memory detection probe 46 for detecting surface defects of precision ferromagnetic components is fixedly arranged at the bottom of the first top plate 45. A controller 8 for controlling the operation of the first conveyor 2, the second conveyor 3, and the magnetic memory detection probe 46 is fixedly arranged on the front side of the U-shaped connecting frame 41.

[0028] By setting the detection assembly 4, first, operate the controller 8 to control the operation of the first conveyor 2 and the second conveyor 3. Then, place the precision ferromagnetic components to be detected at intervals on the first conveyor 2 in sequence. Then, the precision ferromagnetic components on the first conveyor 2 will fall onto the guide table 43 at the top of the support table 42. Then, the surface of the precision ferromagnetic components is detected by the magnetic memory detection probe 46 at the bottom of the first top plate 45 (the working principle of magnetic memory detection is to use the magnetic memory effect to detect defects on the surface or inside of an object, and determine the state of the material by collecting and analyzing the change of the magnetic field). Then, the magnetic memory probe will capture the magnetic field information of the defect characteristics of the precision ferromagnetic components, convert it into an electrical signal, and send the electrical signal to the controller 8, so as to facilitate detecting the surface defect situation of the precision ferromagnetic components, with high detection accuracy, high detection rate, and low error rate.

[0029] As Figures 1-4As shown in the figure, a pushing component 5 is fixedly arranged on the top of the workbench 1, which is used to automatically separate the precision ferromagnetic components with surface defects, improving the detection efficiency. The pushing component 5 includes a second top plate 51, which is arranged on the top of the workbench 1. Two slots are opened at the bottom of the second top plate 51. A threaded rod 52 is connected between the front and rear ends inside one slot through bearings. A limiting rod 54 is fixedly arranged between the front and rear ends inside the other slot. A threaded block 53 is threadedly connected to the threaded rod 52. A slider 55 is slidably connected to the limiting rod 54. The bottom of the slider 55 and the threaded block 53 are fixedly provided with the same pushing plate 56. A photoelectric sensor 58 is fixedly arranged at the top of the front side of the pushing plate 56.

[0030] A rubber pad 57 is inlaid on the front side of the pushing plate 56.

The four corners of the bottom of the second top plate 51 and the front and rear sides of the top of the workbench 1 are fixedly connected through second connecting rods 510. An opening is opened on the front side of the workbench 1, and the opening is located between the two second connecting rods 510 on the front side, which is convenient for separating the precision ferromagnetic components with surface defects.

[0031] By setting the pushing component 5, the precision ferromagnetic components after the detection will fall onto the top of the second conveyor 3 and be conveyed again. When the precision ferromagnetic components with surface defects on the top of the second conveyor 3 pass through the photoelectric sensor 58, the photoelectric sensor 58 will detect the precision ferromagnetic components. The photoelectric sensor 58 will send a signal to the controller 8, and the controller 8 will simultaneously control the motor 59 to work. The motor 59 will drive the threaded rod 52 to rotate and drive the threaded block 53 thereon to move back and forth along the slot;

[0032] At the same time, the slider 55 slides back and forth along the limiting rod 54 to limit the movement of the threaded block 53 and drive the pushing plate 56 and the rubber pad 57 at the bottom to move back and forth, so as to push the precision ferromagnetic components with surface defects into the collection box 7 on the front side of the workbench 1 for centralized collection;

[0033] Similarly, the precision ferromagnetic components without surface defects will be conveyed from the top of the second conveyor 3 to the end far away from the first conveyor 2, so as to facilitate the automatic separation of the precision ferromagnetic components with surface defects, improve the detection efficiency and be convenient to use.

[0034] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
