[0002] Using the line structured light method, a high-contrast light strip is projected on the measured area, and the scattered light is received by the area array camera to obtain the cross-sectional shape or contour of the illuminated area on the surface. Therefore, we call the sensor implemented by line structured light technology a laser profile sensor.

[0003] With the improvement of industrial production line automation technology, the structure of the parts to be processed is becoming more and more complex. In order to adapt to various processed parts, laser profile sensors are widely used to extract the surface profile of the parts to be processed. Sensor abnormality is a common fault of industrial equipment. The types of abnormalities include constant value abnormality, short-term abnormality, noise abnormality, deviation abnormality, etc. Sensor abnormality causes false alarms in the monitoring system and malfunction of the control system, which brings hidden dangers to industrial production safety. Therefore, it is necessary to use an abnormality detection device to detect it.

[0004] Currently, most sensor detection devices on the market connect the sensor to the detection device through wiring for detection. However, the length of the connecting wire on the sensor is limited, and it is impossible to connect it to the detection device stably during detection, which makes it easy for the wiring to detach during detection, reducing the detection effect. In addition, the sensor is easily shaken by external force during detection, reducing the stability of the detection. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 The utility model provides a technical solution: a high-precision laser profile sensor abnormality detection device, including a base 1, a pillar 2 is fixed on the top of the base 1, a groove 21 is provided inside the pillar 2, a sliding block 3 that can be lifted and slid is provided inside the groove 21, a lifting platform 4 is fixed on the end side of the sliding block 3, an empty groove 5 is provided inside the lifting platform 4, a placing plate 6 is fixed inside the empty groove 5, a laser profile sensor body 7 is placed on the top of the placing plate 6, a detection wiring 8 is connected to the top of the laser profile sensor body 7, and an abnormality detector 9 is connected to the other end of the detection wiring 8.

[0029] It should be noted that the anomaly detector 9 belongs to the existing technology in this field, and its detection method adopts the existing technology, and the main innovation is not in the detection method, so the anomaly detector 9 is summarized and will not be described in detail.

[0030] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a support 31 is fixed to the top surface of the base 1, a support plate 32 is fixed to the side wall of the support 31, a motor 33 is fixed to the top of the support plate 32, a transmission rod 34 is fixedly connected to the output end of the motor 33, a rotating rod 35 is fixed to the end of the transmission rod 34, a worm 36 is fixedly sleeved on the outside of the rotating rod 35, a worm wheel 37 is meshed at the side end of the worm 36, a rotating rod 38 is fixed in the middle of the worm wheel 37, and the rotating rod 38 is rotatably connected to the base 1.

[0031] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a screw rod 39 is fixed to the end of the rotating rod 38, the slider 3 is threadedly sleeved with the screw rod 39, and the screw rod 39 is placed in the support 2 for rotational movement.

[0032] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, telescopic rods 61 are fixed on both sides of the placement plate 6, connecting plates 62 are fixed to the ends of the telescopic rods 61, and clamping plates 64 are fixed on the top of the connecting plates 62, and the clamping plates 64 are in contact with the side walls of the laser profile sensor body 7.

[0033] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a spring 63 is fixedly connected between the connecting plate 62 and the placing plate 6 , and two springs 63 are symmetrically arranged about the axis of the telescopic rod 61 .

[0034] It should be noted that the laser profile sensor body 7 is clamped by the clamping plate 64, and the spring 63 has elastic properties. The elastic properties enable the clamping plate 64 to be suitable for clamping laser profile sensors of different sizes, thereby increasing the scope of application.

[0036] It should be noted that the abnormality detector 9 is connected to the laser profile sensor body 7 via the detection connection 8, and the signal is transmitted via the detection connection 8, so that the abnormality detector 9 detects various performances on the sensor.

When the laser profile sensor body 7 is placed, the spring 63 releases the pressure to drive it to reset, and the telescopic rod 61 also shrinks synchronously, so that the clamping plate 64 is stably clamped on the side wall of the laser profile sensor body 7 to fix it, so that the sensor will not shake when detecting abnormalities, thereby improving the stability of detection;

[0040] Then, the connection height is adjusted according to the length of the detection wiring 8, and the motor 33 is started to drive the transmission rod 34 to drive the rotating rod 35 to rotate.
