The device can install the movable plate 11 at different positions on the second adjusting block 805 through the movable groove 9 and the first sliding rod 10. The second electric push rod 12 and the third electric push rod 13 can support the movable plate 11 at the corresponding position when extended or shortened, so that the device can adjust and fix the position of the second adjusting block 805, thereby changing the detection height and the front and rear position or left and right position of the detection.

[0028] In this embodiment, a bottom groove 19 is opened at the bottom of the limiting plate 15, and a second sliding rod 20 is fitted in the bottom groove 19. An extension plate 21 is fixedly connected below the second sliding rod 20. The length of the extension plate 21 is greater than the width of the limiting plate 15. The bottom groove 19 and the first mounting groove 16 on the same limiting plate 15 are perpendicular to each other. The bottom groove 19 enables the second sliding rod 20 to be stably installed on different limiting plates 15. When the second sliding rod 20 and the extension plate 21 are installed on the limiting plate 15, the range of movement of the device during detection can be extended to adapt to the testing of larger sensitive components.

[0029] In this embodiment, the adjustment component 22 includes a fourth electric push rod 2201 fixedly connected to the second adjustment block 805, the fourth electric push rod 2201 is fixedly connected to the outer frame 2202, a first guide rod 2203 is fixedly connected between the first adjustment block 705 and the second adjustment block 805, the first guide rod 2203 runs through the interior of the outer frame 2202, a motor 2204 is installed on the outer frame 2202, a bidirectional screw 2205 is fixedly connected to the output shaft of the motor 2204, the bidirectional screw 2205 is threadedly connected to the connecting block 23, and the second guide rod 2203 is provided on both sides of the connecting block 23. 206, the second guide rod 2206 and the outer frame 2202 are fixedly connected, the threads on both sides of the bidirectional screw 2205 are rotated in opposite directions, and the fourth electric push rod 2201 on the device is used to adjust the left and right position of the outer frame 2202. The outer frame 2202 can slide left and right on the first guide rod 2203, and the bidirectional screw 2205 is driven to rotate by the motor 2204, driving the two adjacent connecting blocks 23 to move toward or away from each other, thereby changing the distance between the two connecting blocks 23, so as to detect the degree of fluctuation at two different positions on the same sensitive element, or detect whether the heights of the same positions on two sensitive elements are the same.

[0030] In this embodiment, the support assembly 25 includes a second mounting groove 2501 provided in the base 1, a support platform 2503 is slidably installed in the second mounting groove 2501, a support ball 2502 is fitted on the top of the support platform 2503, a spring 2504 is fixedly connected to the bottom of the support platform 2503, a groove 2505 is provided on the support platform 2503, and the support balls 2502 are evenly distributed along the circumference of the base 1. The top of the support ball 2502 abuts against the first support plate 301. When the device adjusts the detection angle, as shown in FIG. Figure 8 As shown, the first support plate 301 is supported by the support balls 2502 when rotating, the springs 2504 can provide supporting force, and the support balls 2502 can rotate in the grooves 2505 on the support platform 2503, thereby reducing the rotation resistance of the first support plate 301.

[0031] Specifically, the present invention is a sensor sensitive element testing device and a testing method thereof. First, as Figure 1-Figure 10 As shown, the base 1 is used to support the entire device, and the rotating component 3 can rotate on the connecting disk 2. When the rotating component 3 rotates, the supporting component 25 is used to support both sides of the rotating component 3 and reduce the rotation resistance of the rotating component 3. The first supporting plate 301 and the second supporting plate 302 can rotate on the connecting disk 2 through the connecting ring 303, thereby changing the placement angle of the sensor sensitive element on the device, thereby changing the test angle of the device. Since there is a gap between the first supporting plate 301 and the base 1, as shown in FIG. Figure 8As shown, the spring 2504 can tighten the support platform 2503 and the support ball 2502 in the second mounting groove 2501 upwards. The support ball 2502 is used to support the first support plate 301 during the rotation process. The spring 2504 can provide supporting force. The support ball 2502 can rotate in the groove 2505 on the support platform 2503, thereby reducing the rotation resistance of the first support plate 301. The sensor sensitive element is placed on the first conveyor belt 4 and moved to the detection area. During the detection, the overall angle of the rotating component 3 is adjusted according to the required detection angle. The initial position of the connecting block 23 and the laser distance sensor 24 is adjusted by the adjustment component 22, and the distance between two adjacent laser distance sensors 24 is changed to adapt to different detection positions. The height difference of different parts on the sensor sensitive element is detected. During the adjustment, as shown in FIG. Figure 7 As shown, the fourth electric push rod 2201 is used to adjust the left and right position of the outer frame 2202. The outer frame 2202 can slide straightly through the first guide rod 2203. The motor 2204 drives the bidirectional screw 2205 to rotate, driving the two adjacent connecting blocks 23 to move toward each other or move away from each other, changing the spacing between the two connecting blocks 23 and the hybrid laser ranging sensor 24, thereby detecting the degree of fluctuation at two different positions on the same sensitive element, or detecting whether the heights of the same positions on two sensitive elements are the same.

[0032] like Figure 1-Figure 7 , Fig. 9 and Fig.11As shown, the initial height and initial position of the adjustment component 22 and the laser distance sensor 24 are changed by the first lifting component 7 and the second lifting component 8. When the left and right positions of the laser distance sensor 24 are adjusted while lifting, the limit plates 15 are installed on the front and rear sides of the first adjustment block 705 on the first lifting component 7. When the laser distance sensor 24 is adjusted front and back while lifting, the limit plates 15 are installed on the left and right sides of the first adjustment block 705 on the first lifting component 7. By rotating the studs 17, the positions of the limit plates 15 at the corresponding positions are changed. The first mounting groove 16 and the protrusion 14 enable the limit plate 15 to move up and down stably. By lifting the limit plate 15 at different positions, the first connecting block 704 and the first rotating block 702 on the upper and lower sides of the first connecting rod 703 can rotate in different directions, thereby changing the adjustment mode of the device. The bottom groove 19 and the second sliding bar 20 enable the extension plate 21 to be stably installed on the corresponding limit plate 15. When the second sliding bar 20 and the extension plate 21 are installed on the limit plate 15, the range of movement of the device during detection can be extended to adapt to the testing of sensitive components with larger sizes. When the first adjustment block 705 moves left and right or moves forward and backward, the first guide rod 2203 can drive the second adjustment block 805 to move left and right or move forward and backward. The second connecting block 804 and the second rotating block 802 on the upper and lower sides of the second connecting rod 803 will rotate inside the second adjustment block 805 and the second fixed block 801 respectively, thereby changing the detection height of the device and changing the initial position of the detection. The movable plate 11 is installed at different positions on the second adjustment block 805 through the movable groove 9 and the first sliding rod 10. The second electric push rod 12 and the third electric push rod 13 can support the movable plate 11 at the corresponding position when extending or shortening, so that the device can adjust and fix the position of the second adjustment block 805, thereby changing the detection height and the front and rear position or left and right position of the detection.

[0033] When the second slide bar 20 and the extension plate 21 are installed on the limit plate 15, the range of movement of the device during detection can be extended. The extension plate 21 can replace the limit plate 15 and maintain abutment with the first fixed block 701 to accommodate the larger sensitive components for testing. After the detection is completed, according to whether the detection error is within the allowable range, the detected sensor sensitive component is pushed to the second conveyor belt 5 through the guide component 6, or directly conveyed through the first conveyor belt 4. The first electric push rod 602 on the extension support block 601 and the guide plate 603 guide the sensitive component to the second conveyor belt 5, and the sensitive component with a larger test error is guided to the rear side of the device, so as to classify different sensitive components.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
