[0030] Reference Figures 1 to 4 , a device for detecting the front and back of a magnetic ring 100, comprising: a magnetic ring 100, a hollow annular structure, one end of the magnetic ring 100 is provided with a flange 180, and the other end is flush with the wall of the magnetic ring 100;

[0031] The clamping unit includes a storage platform 110, which is fixed to the frame and suitable for placing the magnetic ring 100. The storage platform 110 is provided with a plurality of notches 190, which are adapted to the flanges 180, and the flanges 180 are snap-fitted to the notches 190. The notches 190 are arranged at intervals along the length direction of the storage platform 110;

[0032] The detection unit includes a conveying track 130, a sliding seat 140 and a laser displacement sensor 170. The conveying track 130 is fixed to the frame, the laser displacement sensor 170 is fixedly installed on the sliding seat 140, and the sliding seat 140 is movably installed on the conveying track 130. The conveying track 130 and the storage platform 110 are parallel to each other;

[0033] The laser displacement sensor 170 reciprocates above the magnetic ring 100 and determines the positive and negative directions of the magnetic ring 100 .

[0034] Reference Figure 1 In some embodiments, a three-color light is also provided on the frame, and the laser displacement sensor 170 may also be replaced by a laser altimeter or an ultrasonic sensor. The size data of the surface of the magnetic ring 100 is obtained by the laser altimeter or the ultrasonic sensor, so as to determine whether the orientation of the magnetic ring 100 is correct. When it is determined that the orientation of the magnetic ring 100 is wrong, the red light of the three-color light is on and an alarm is sounded, and then the worker adjusts the direction of the magnetic ring 100 that is in the wrong orientation.

[0035] When the laser displacement sensor 170 is working, the laser transmitter shoots the laser through the lens to the surface of the object to be measured. The laser reflected by the object passes through the receiver lens and is received by the internal imaging element. The projection positions of light spots at different distances on the imaging element are different. According to the imaging position and the optical projection relationship, the distance of the object to be measured can be obtained. Using this principle, it is possible to measure whether the magnetic ring 100 is placed upside down. When the magnetic ring 100 is placed upside down, that is, when the flanges 180 of two adjacent magnetic rings 100 abut against each other, the laser displacement sensor 170 measures that the thickness of the flange 180 exceeds the preset value, then it is determined that the magnetic ring 100 is placed upside down, and the red light of the three-color light is on and an alarm is sounded.

[0036] The storage table 110 is used to place the magnetic ring 100. The magnetic ring 100 can be clamped on the storage table 110, and the flange 180 of the magnetic ring 100 can be clamped in the notch 190 to achieve pre-positioning, which is convenient for fixing the magnetic ring 100. The magnetic ring 100 is placed in the notch 190 and is not easy to shift; the sliding seat 140 can drive the laser displacement sensor 170 to move above the magnetic ring 100, and can realize one-time loading and detection of multiple magnetic rings 100, thereby improving the efficiency of detection; the present device obtains the surface size data of the magnetic ring 100 through the laser displacement sensor 170, thereby judging whether the placement of the magnetic ring 100 is correct, and can realize automated inspection and reduce errors.

[0037] The distance between two adjacent notches 190 is equal to the thickness of the magnetic ring 100. To ensure that the magnetic rings 100 are closely arranged, the storage table 110 can hold more magnetic rings 100, and multiple magnetic rings 100 can be tested at one time without repeated loading and unloading, thereby improving the efficiency of the test. The distance that the sliding seat 140 moves each time is equal to the thickness of the magnetic ring 100, ensuring that each magnetic ring 100 is tested. It is understandable that the conveying track 130 and the sliding seat 140 can be ball screw subassemblies, which have the characteristics of low friction, smooth operation, and high precision.

[0038] The laser displacement sensor 170 is disposed directly above the storage platform 110, and the laser displacement sensor 170 and the axial center line of the magnetic ring 100 are perpendicular to each other, so as to improve the detection accuracy of the laser displacement sensor 170 and avoid false alarms.

[0039] Reference Figure 1 and Figure 4 , a plurality of magnetic rings 100 are placed on the storage table 110, and a transfer rod (not shown in the figure) is inserted along the axial center line of the magnetic ring 100. Loading and unloading materials by using the transfer rod can improve the efficiency of loading and unloading materials and realize batch loading and unloading. It can be understood that the shape of the transfer rod can be a square rod or a cylindrical rod. In some preferred embodiments, the shape of the transfer rod is a cylindrical rod. The cylindrical transfer rod is more suitable for the shape of the inner wall of the magnetic ring 100, and the magnetic ring 100 is more stable when being transported and is not easy to loosen.

[0040] The cross section of the storage platform 110 along the direction in which the sliding seat 140 moves is semi-circular, and the shape of the storage platform 110 is adapted to the shape of the magnetic ring 100. The storage platform 110 is adapted to the shape of the magnetic ring 100, which can ensure that the magnetic ring 100 is placed more stably and is not easy to move when impacted by external forces. It is understandable that the shape of the storage platform 110 can be adaptively modified according to the shape of the magnetic ring 100 to adapt to magnetic rings 100 of different shapes and sizes.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The storage table 110 is provided with a plurality of mounting grooves 120, and the extension direction of the mounting grooves 120 is parallel to the movement direction of the sliding seat 140, and the storage table 110 is fixed to the frame through the mounting grooves 120. It is convenient to adjust the initial position of the laser displacement sensor 170 and the position of the origin, so as to improve the efficiency of the machine adjustment. The storage table 110 and the conveying track 130 are arranged parallel to each other to ensure that the magnetic ring 100 is also parallel to the conveying track 130 after being placed. The storage table 110 is provided with four mounting grooves 120, and the four mounting grooves 120 are respectively arranged at the ends of the storage table 110. Fixing the storage table 110 by the four mounting grooves 120 can ensure that the storage table 110 is firmly installed and not easy to loosen.

[0042] Reference Figure 1 The sliding seat 140 further includes a first connecting plate 150 and a second connecting plate 160. One end of the first connecting plate 150 is fixedly connected to the sliding seat 140, and the other end is fixedly connected to the second connecting plate 160. The laser displacement sensor 170 is fixedly mounted on the second connecting plate 160, and the second connecting plate 160 is arranged toward the storage platform 110. It can be understood that by replacing the first connecting plate 150 and the second connecting plate 160 of different sizes, the relative distance between the laser displacement sensor 170 and the storage platform 110 can be adjusted, so as to adapt to magnetic rings 100 of different sizes and models, thereby improving the applicability of the device.

[0043] The minimum distance between the center of the laser displacement sensor 170 and the center of the storage platform 110 is A, which satisfies: 6.5cm≤A≤13.5cm. Setting a certain distance can facilitate the loading and unloading of the magnetic ring 100 and prevent the laser displacement sensor 170 from affecting the loading and unloading of the magnetic ring 100. In some preferred embodiments, the minimum distance between the center of the laser displacement sensor 170 and the center of the storage platform 110 is 20cm, which will not affect the accuracy of the laser displacement sensor 170 and also provide enough space for loading and unloading.

[0044] Reference Figure 5 and Figure 6In some embodiments, the diameter of the wall of the magnetic ring 100 is 33.7 mm, and the diameter of the flange 180 of the magnetic ring 100 is 35.4 mm. The laser emitted by the laser displacement sensor 170 can measure the height of the corresponding position of the magnetic ring 100. The detection principle of the laser displacement sensor 170 is: the initial position of the laser displacement sensor 170 is first aligned with the flange 180 of the magnetic ring 100. After completing the detection of the first magnetic ring, the laser displacement sensor 170 moves a distance of the height of the magnetic ring and measures the height of the current position of the second magnetic ring. If the magnetic ring is placed as shown in Figure 6 As shown, after the laser displacement sensor 170 moves a distance of the height of the magnetic ring, it is still aligned with the flange 180 of the second magnetic ring. At this time, the device determines that the magnetic ring is placed correctly; if the magnetic ring is placed as shown in Figure 5 As shown, after the laser displacement sensor 170 moves a distance of the height of a magnetic ring, it is aligned with the wall of the second magnetic ring at 33.7 mm. At this time, the device determines that the magnetic ring is placed incorrectly, the device stops and alarms.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
