[0021] The present invention has at least the following beneficial effects:

[0022] 1. When the sensor test verification equipment is used, the height and angle are synchronized, so that the infrared sensor can more accurately capture the position and temperature changes of the mobile heating element. By dynamically adjusting the position and angle of the sensor, it can be ensured that it always remains within the optimal detection range, thereby improving the accuracy and reliability of the detection, and also improving the detection efficiency;

[0023] In addition, adding a rotation and swing function to the infrared sensor can expand its detection range, help improve detection efficiency in complex environments and reduce blind spots. By adding an automatic lifting function, the infrared sensor can adjust its detection distance and height as needed, which helps to quickly switch between target objects at different heights and distances, improve the flexibility and adaptability of the detection system, and further improve the creativity and adaptability of the sensor testing system. In addition, the height and angle adjustments can be used synchronously and separately, without the need for manual adjustment by staff, and multiple groups of usage effects can be achieved, thereby reducing human intervention and errors, allowing the infrared sensor to adapt to different detection environments and needs, optimizing the detection range, and helping to maintain stable detection performance in complex environments.

[0024] 2. When the sensor test and verification equipment is in use, the angle of the infrared sensor is adjusted by rotating the mounting table. The rotation of the mounting table drives the lifting drum, which is driven to rotate by the meshing cooperation of the transmission gear and the gear ring. The rotation of the lifting drum drives the infrared sensor up and down through the rolling cooperation of the guide wheel and the special-shaped guide groove, thereby realizing the synchronous operation of height and angle, so that the infrared sensor can more accurately capture the position and temperature changes of the moving heating element.

[0025] 3. When the sensor test and verification equipment is in use, the second drive motor drives the drive gear to rotate, and the drive gear meshes with the two tooth plates, so that the two slides move alternately, so that the upper and lower guide wheels can be adjusted. When the upper guide wheel is in contact with the special-shaped guide groove, the lower guide wheel is disengaged from the special-shaped guide groove. Conversely, the upper guide wheel is disengaged from the special-shaped guide groove, and the lower guide wheel is in contact with the guide groove, thereby adjusting the up and down movement amplitude of the infrared sensor. In addition, the drive gear is meshed with the tooth plate to make the two guide wheels disengage from the special-shaped guide groove, thereby releasing the lifting function of the infrared sensor.

[0026] 4. When the sensor test and verification equipment is used, the connection between the guide wheel and the special-shaped guide groove can be detected by extending and retracting the sleeve and the sleeve rod in conjunction with the use of a pressure sensor to prevent the guide wheel from being separated from the special-shaped guide groove.

[0027] 5. When the sensor test and verification equipment is in use, the sliding shell moves upward, and the cam is rolled and connected to the outside of the special-shaped abutment plate 29. Since the special-shaped abutment plate is installed in the mounting shell through a torsion spring and can rotate, when the cam moves to the recessed part of the special-shaped abutment plate, the special-shaped abutment plate rotates through the deformation ability of the torsion spring, so that the card plate is plugged into the sliding shell, thereby achieving locking positioning.

[0047] Specifically, Figure 4 - Figure 6 As shown, the interior of the housing 6 and the mounting housing 8 are both hollow, and the interior of the housing 6 and the mounting housing 8 are both provided with through holes, and the first rotating shaft 11 extends to the outside of the housing 6 through the through holes, and the mounting frame 18 extends to the outside of the mounting housing 8 through the through holes.

The guide structure includes an annular guide rail fixedly mounted on the upper surface of the housing 6 and a guide pulley mounted on the lower surface of the mounting platform 7, and a rotating shaft fixed to the lower surface of the mounting platform 7 is rotatably installed in the guide pulley. The guide pulley extends into the annular guide rail and is rollingly connected to its inner wall to ensure the movement stability of the infrared sensor 2. An annular scale is installed on the mounting platform 7 to further improve the detection accuracy. The mounting platform 7 can swing back and forth during detection.

[0049] In this embodiment, if Figure 8 and Fig.14 As shown, the elastic telescopic rod 19 includes a sleeve 1901 and a sleeve rod 1902 that are telescopically connected, and one end of the sleeve rod 1902 extending into the interior of the sleeve 1901 is fixedly mounted with a reset spring 1903 and a pressure sensor 1904, and the other end of the reset spring 1903 is fixed to the interior of the sleeve 1901, and the guide wheel 20 is rotatably mounted on the end of the sleeve rod 1902 away from the sleeve 1901.

The two sleeves 1901 are bolted to the same side of the two slides 25 , and the two tooth plates 26 are meshed with the driving gear 24 .

[0054] In addition, the special-shaped guide groove 21 is arranged around the outside of the lifting drum 9, and the special-shaped guide groove 21 is composed of a V-shaped groove and an annular groove, and the two ends of the annular groove are connected to the two sides of the V-shaped groove. The V-shaped grooves of the two special-shaped guide grooves 21 can also be extended to adjust the amplitude of the infrared sensor 2 when it is lifted or lowered. At the same time, a spring can be installed on the bottom side of the sliding shell 17 so that the sliding shell 17 can be reset better.

When the actual temperature reaches the set value, the information processing module 103 controls the mobile heating element 102 to stop heating, otherwise it still needs to continue heating. When the heating plate 105 and the mobile heating element 102 are heated to the set temperature, the infrared sensor 2 is started to sense the mobile heating element 102, and the infrared sensor 2 will send a sensing signal when it is in the sensing range;

[0057] Next, the angle of the infrared sensor 2 is adjusted by rotating the mounting platform 7. The mounting platform 7 rotates to drive the lifting drum 9, which is driven to rotate by the meshing cooperation of the transmission gear 16 and the ring gear 14. The lifting drum 9 rotates through the rolling cooperation of the guide wheel 20 and the special-shaped guide groove 21 to drive the infrared sensor 2 to move up and down, thereby realizing the synchronous operation of height and angle, so that the infrared sensor 2 can more accurately capture the position and temperature changes of the mobile heating element 102.
