Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0037] Embodiment 1, as Figures 1 - 11As shown in the figure, this embodiment proposes a sensor sensitive element testing device, which includes a base 1. A connecting plate 2 is fixedly arranged on the base 1. A rotating assembly 3 is rotatably installed on the connecting plate 2. A first conveyor belt 4 and a second conveyor belt 5 are installed on the connecting plate 2. A guiding assembly 6 is arranged inside the first conveyor belt 4. The guiding assembly 6 cooperates with the first conveyor belt 4 and the second conveyor belt 5, enabling the device to classify and convey sensor sensitive elements with different detection results. First lifting assemblies 7 and second lifting assemblies 8 are respectively installed on both sides of the rotating assembly 3. Limit plates 15 are installed around the first lifting assembly 7. By installing the limit plates 15 at different positions on the first lifting assembly 7, the moving direction of the limit plates 15 is restricted. When the limit plates 15 are located on the left and right sides of the first lifting assembly 7, the device can move forward and backward while lifting. When the limit plates 15 are located at the front and rear positions of the first lifting assembly 7, the device can move left and right while lifting. A stud 17 is rotatably installed on the limit plate 15. The stud 17 is in threaded connection with the first lifting assembly 7. The top of the stud 17 is fixedly connected to a third fixing block 18. An adjusting assembly 22 is installed between the first lifting assembly 7 and the second lifting assembly 8. An adapter block 23 is installed on the adjusting assembly 22. A laser distance sensor 24 is arranged at the bottom of the adapter block 23. A support assembly 25 is installed inside the base 1. The stud 17 can adjust the initial height of the limit plate 15. Cooperating with the first lifting assembly 7 and the second lifting assembly 8, it can limit the moving range when the laser distance sensor 24 moves left and right or front and back. Furthermore, when testing sensitive elements of different sizes, the testing range is changed, making the testing result of the device more accurate.

[0038] Embodiment 2, as Figures 1 - 11 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a sensor sensitive element testing device.

[0039] In this embodiment, the rotating assembly 3 includes a connecting ring 303 rotatably installed on the connecting plate 2. First support plates 301 and second support plates 302 are respectively fixedly connected to both sides of the connecting ring 303. There is a gap between the first support plate 301 and the base 1. The upper surfaces of the first support plate 301 and the second support plate 302 are flush with the upper surface of the connecting plate 2. The first support plate 301 and the second support plate 302 can rotate on the connecting plate 2 through the connecting ring 303, thereby changing the placement angle of the sensor sensitive elements on the device and thus changing the testing angle of the device.

[0040] In this embodiment, the guiding assembly 6 includes a support block 601 fixedly connected to the connecting plate 2. A first electric push rod 602 is fixedly installed on the support block 601. A guiding plate 603 is fixedly arranged on the first electric push rod 602. By extending the first electric push rod 602 on the support block 601, the guiding plate 603 guides the sensitive elements to different conveyor belts (such asFigure 1 , Figure 3 and Figure 5 As shown in Figure 5 , the device can direct the sensitive components with large test errors to the rear side of the device, thereby classifying different sensitive components.

[0041] In this embodiment, the first lifting assembly 7 includes a first fixing block 701 fixedly connected to the first support plate 301. A first rotating block 702 is rotatably installed in the first fixing block 701. A first connecting rod 703 is fixedly connected to the first rotating block 702. A first connecting block 704 is fixedly connected to the first connecting rod 703. A first adjusting block 705 is rotatably arranged outside the first connecting block 704. A fixing column 706 is welded above the first adjusting block 705. A fixing plate 707 is welded above the fixing column 706. The stud 17 is in threaded connection with the fixing plate 707. Convex blocks 14 are fixedly connected to the periphery of the first adjusting block 705. A first installation groove 16 for the convex blocks 14 to slide is formed on the limiting plate 15. By rotating the stud 17, the position of the limiting plate 15 at the corresponding position can be changed. The first installation groove 16 and the convex blocks 14 enable the limiting plate 15 to move up and down stably. By lifting the limiting plates 15 at different positions, the first connecting blocks 704 and the first rotating blocks 702 on the upper and lower sides of the first connecting rod 703 rotate in different directions, thereby changing the adjustment method of the device.

[0042] In this embodiment, the second lifting assembly 8 includes a second fixing block 801 fixedly connected to the second support plate 302. A second rotating block 802 is fixedly connected to the second fixing block 801. A second connecting rod 803 is fixedly connected to the second rotating block 802. A second connecting block 804 is fixedly arranged on the second connecting rod 803. A second adjusting block 805 is rotatably installed outside the second connecting block 804. When the second adjusting block 805 is pushed to the right, the second connecting blocks 804 and the second rotating blocks 802 on the upper and lower sides of the second connecting rod 803 will rotate inside the second adjusting block 805 and the second fixing block 801 respectively, thereby changing the detection height of the device and the initial detection position at the same time.

[0043] In this embodiment, a moving groove 9 is formed on the second adjusting block 805. A first sliding rod 10 is fitted in the moving groove 9. A movable plate 11 is fixedly connected to the first sliding rod 10. A second electric push rod 12 and a third electric push rod 13 for supporting the movable plate 11 are installed on the second support plate 302. The device can install the movable plate 11 at different positions on the second adjusting block 805 through the moving groove 9 and the first sliding rod 10. When the second electric push rod 12 and the third electric push rod 13 extend or contract, they can support the movable plate 11 at the corresponding position, so that the device can adjust and fix the position of the second adjusting block 805, and further change the detection height and the front-back position or left-right position of the detection.

[0044] In this embodiment, a bottom groove 19 is formed in the bottom of the limit plate 15. 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 limit plate 15. The bottom groove 19 and the first installation groove 16 on the same limit plate 15 are perpendicular to each other. The bottom groove 19 enables the second sliding rod 20 to be stably installed on different limit plates 15. When the second sliding rod 20 and the extension plate 21 are installed on the limit plate 15, the moving range during device detection can be extended to adapt to the testing of sensitive components with larger sizes.

[0045] In this embodiment, the adjustment assembly 22 includes a fourth electric push rod 2201 fixedly connected to the second adjustment block 805. An outer frame 2202 is fixedly connected to the fourth electric push rod 2201. 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 penetrates through the interior of the outer frame 2202. A motor 2204 is installed on the outer frame 2202. A bidirectional screw rod 2205 is fixedly connected to the output shaft of the motor 2204. The bidirectional screw rod 2205 is in threaded connection with the connection block 23. Second guide rods 2206 are penetrated through both sides of the connection block 23. The second guide rods 2206 are fixedly connected to the outer frame 2202. The thread directions on both sides of the bidirectional screw rod 2205 are opposite. The fourth electric push rod 2201 on the device is used to adjust the left and right positions of the outer frame 2202. The outer frame 2202 can slide left and right on the first guide rod 2203. By driving the bidirectional screw rod 2205 to rotate through the motor 2204, the adjacent two connection blocks 23 are driven to move towards each other or away from each other, so as to change the distance between the two connection blocks 23, thereby detecting the undulation degree of two different positions on the same sensitive component, or detecting whether the heights of the same position on two sensitive components are the same.

[0046] In this embodiment, the support assembly 25 includes a second installation groove 2501 formed in the base 1. A support table 2503 is slidably installed in the second installation groove 2501. A support ball 2502 is fitted above the support table 2503. A spring 2504 is fixedly connected to the bottom of the support table 2503. A groove 2505 is formed in the support table 2503. 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 Figure 8 shown, when the first support plate 301 rotates, it is supported by the support ball 2502. The spring 2504 can provide a supporting force. The support ball 2502 can rotate in the groove 2505 on the support table 2503, thereby reducing the rotation resistance of the first support plate 301.

[0047] Specifically, the present invention is a sensor sensitive component testing device and its testing method. First, as Figures 1 - 10As shown, the base 1 is used to support the entire device. The rotating assembly 3 can rotate on the connecting plate 2. When the rotating assembly 3 rotates, the supporting assembly 25 is used to support both sides of the rotating assembly 3 and reduce the rotational resistance of the rotating assembly 3. The first support plate 301 and the second support plate 302 can rotate on the connecting plate 2 through the connecting ring 303, thereby changing the placement angle of the sensor sensitive element on the device, and thus changing the testing angle of the device. Since there is a gap between the first support plate 301 and the base 1, as Figure 8 shown, the spring 2504 can tightly support the support table 2503 and the support ball 2502 in the second mounting groove 2501 upward. The support ball 2502 is used to support the first support plate 301 during rotation. The spring 2504 can provide a supporting force, and the support ball 2502 can rotate in the groove 2505 on the support table 2503, thereby reducing the rotational resistance of the first support plate 301. Place the sensor sensitive element on the first conveyor belt 4 and move it to the detection area. During detection, according to the required detection angle, adjust the overall angle of the rotating assembly 3, adjust the initial positions of the connecting block 23 and the laser distance sensor 24 through the adjustment assembly 22, and change the distance between adjacent two laser distance sensors 24 to adapt to different detection positions, and detect the height difference of different parts on the sensor sensitive element. During adjustment, as Figure 7 shown, the fourth electric push rod 2201 is used to adjust the left and right positions of the outer frame 2202. The outer frame 2202 can slide straight through the first guide rod 2203. The motor 2204 drives the bidirectional screw 2205 to rotate, driving the adjacent two connecting blocks 23 to move towards each other or away from each other, changing the distance between the two connecting blocks 23 and the laser distance sensor 24, thereby detecting the undulation degree of two different positions on the same sensitive element, or detecting whether the heights of the same position on two sensitive elements are the same.

[0048] Such as Figures 1 - 7 、 Figure 9 and Figure 11As shown in the figure, the initial height and initial position of the adjusting component 22 and the laser ranging sensor 24 are changed by the first lifting component 7 and the second lifting component 8. When adjusting the left and right positions of the laser ranging sensor 24 while lifting, the limiting plate 15 is installed on the front and rear sides of the first adjusting block 705 on the first lifting component 7. When adjusting the laser ranging sensor 24 back and forth while lifting, the limiting plate 15 is installed on the left and right sides of the first adjusting block 705 on the first lifting component 7. By rotating the stud 17, the position of the limiting plate 15 at the corresponding position is changed. The first installation groove 16 and the convex block 14 enable the limiting plate 15 to move up and down stably. By lifting the limiting plates 15 at different positions, the first connection blocks 704 and the first rotating blocks 702 on the upper and lower sides of the first connecting rod 703 rotate in different directions, thereby changing the adjustment method of the device. The bottom groove 19 and the second sliding rod 20 enable the extension plate 21 to be stably installed on the corresponding limiting plate 15. When the second sliding rod 20 and the extension plate 21 are installed on the limiting plate 15, the moving range of the device during detection can be extended to adapt to the testing of larger-sized sensitive components. When the first adjusting block 705 moves left and right or back and forth, the second adjusting block 805 can be driven to move left and right or back and forth by the first guide rod 2203. The second connection blocks 804 and the second rotating blocks 802 on the upper and lower sides of the second connecting rod 803 will rotate inside the second adjusting block 805 and the second fixing block 801 respectively, thereby changing the detection height of the device and the initial position of detection at the same time. The movable plate 11 is installed at different positions on the second adjusting block 805 through the moving 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 adjusting block 805, and further change the detection height and the front and back positions or left and right positions of detection.

[0049] When the second sliding rod 20 and the extension plate 21 are installed on the limiting plate 15, the moving range of the device during detection can be extended. The extension plate 21 can replace the limiting plate 15 and keep in contact with the first fixing block 701 to adapt to the testing of larger-sized sensitive components. After the detection is completed, according to whether the detection error is within the allowable range, the detected sensor sensitive component is pushed onto the second conveyor belt 5 through the guiding component 6, or directly conveyed through the first conveyor belt 4. By extending the first electric push rod 602 on the supporting block 601, the guiding plate 603 guides the sensitive component onto the second conveyor belt 5, and the sensitive component with a large test error is guided to the rear side of the device, so as to classify different sensitive components.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
