[0035] Reference Figure 1 A transfer block 12 is slidably installed on the surface of the frame 1, and a transfer channel 13 is opened on the surface of the transfer block 12. An external feeding device is installed at one end of the transfer channel 13. The feeding device is used to transfer the NdFeB magnets 7 one by one into the transfer channel 13. The frame 1 is provided with a third cylinder 14 for driving the transfer block 12 to slide, and the detection mechanism 4 is provided with a conveying channel 22; starting the third cylinder 14 can make the transfer channel 13 and the conveying channel 22 face each other.

[0036] There are two groups of detection mechanisms 4, which are respectively located on opposite sides of the detection part 2; the detection mechanism 4 includes a first cylinder 41 and a detection rod 42, the first cylinder 41 is installed on the surface of the frame 1, and the movable plug of the first cylinder 41 is arranged opposite to the detection part 2; the detection rod 42 is fixed to the movable plug of the first cylinder 41, and the side wall of the detection part 2 is provided with a detection hole 24 connected with the conveying channel 22, and the detection rod 42 is inserted into the detection hole 24.

[0037] Reference Figure 3A detection groove 23 is provided on the inner wall of the conveying channel 22 away from the detection hole 24, and the extension direction of the detection groove 23 is in the same direction as the extension direction of the conveying channel 22; and the length of the detection groove 23 is less than the length of the NdFeB magnet 7. When the detection rod 42 is used to abut against the side wall of the NdFeB magnet 7, the two ends of the NdFeB magnet 7 can be respectively abutted against the two sides of the detection groove 23; thereby, the force applied by the detection rod 42 to the NdFeB magnet 7 can be concentrated, thereby accurately detecting whether there are cracks in the product and improving the accuracy of detection.

[0038] Reference Figure 1 The frame 1 is tiltedly provided with a discharge plate 15, which is located at one end of the detection part 2 away from the mounting seat 11; when the NdFeB magnets 7 are detected, they can enter the discharge plate 15 through the feeding channel, so as to collect all the NdFeB magnets 7 in a centralized manner.

[0039] The implementation principle of Example 1 of the present application is:

[0040] The automated operation of pushing the NdFeB magnet 7 from the transfer channel 13 into the conveying channel 22 by the second cylinder 31 can initially improve production efficiency; and when the NdFeB magnet 7 passes through the detection hole 24, the first cylinder 41 is used to abut the detection rod 42 against the NdFeB magnet 7, so that it can be detected whether it will break, so as to detect whether the quality of the product meets the standards, thereby reducing the situation where the staff members fold multiple products and cause finger pain.

[0041] And by providing two groups of detection mechanisms 4, different directions of the NdFeB magnetic force can be detected, which increases the dimension and comprehensiveness of the detection and further improves the reliability of the detection results.

[0042] Embodiment 2:

[0043] The embodiment of the present application discloses a crack detection device.

[0044] Reference Figure 5 The difference between Example 2 of the present application and Example 1 is that the distance between the two inner walls of the conveying channel 22 away from the detection part 2 is smaller than the distance between the two inner walls of the middle part of the conveying channel 22. Since the cross-section of the neodymium iron boron magnet 7 is circular, the possibility of the magnet detaching from the conveying channel 22 under the push of the detection rod 42 can be reduced.

[0045] A collecting groove 16 is provided on the side wall of the conveying channel 22. The collecting groove 16 is located on the side of the detection hole 24 away from the mounting seat 11. The length of the collecting groove 16 is less than the length of the NdFeB magnet 7. A collecting box 6 is provided at the bottom of the detection part 2. The collecting box 6 is connected to the collecting groove 16.

The two ends of the spring 52 are respectively connected to the rejection block 51 and the inner wall of the rejection groove 25, and the elastic force of the spring 52 is used to drive the rejection block 51 to move toward one side of the collecting groove 16.

[0047] The implementation principle of Example 2 of the present application is:

[0048] Since the length of the unqualified product after breaking will be smaller than the length of the collecting groove 16, when the unqualified product is completely pushed into the position opposite to the collecting groove 16, the rejection block 51 can push it into the collecting groove 16 under the elastic force of the spring 52, thereby automatically rejecting and centrally collecting the unqualified products.

[0049] Furthermore, when the pushing rod 32 pushes the products in the transfer channel 13 into the conveying channel 22, all products can be moved in the conveying channel 22, so that the next product can abut against the guide surface 53, and the rejection block 51 enters the rejection groove 25 under the guidance of the guide surface 53, so that qualified products pass through the rejection groove 25, and unqualified products are pushed into the collection box 6 when passing through the collection groove 16.

[0050] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
