[0054] The following Figures 1 to 5 makes a detailed description of the test tooling of the present utility model.
[0055] As Figures 1 to 3 shown, a specific embodiment of the present utility model provides a test tooling. The test tooling includes a first mounting platform 100, a second mounting platform 200, a distance adjustment platform 300, and an angle adjustment platform 400.
[0056] Among them, the first mounting platform 100 is used to drive the black body to move along the Z axis. Along the X axis, the second mounting platform 200 is arranged on one side of the first mounting platform 100. The distance adjustment platform 300 is connected to the first mounting platform 100 or / and the second mounting platform 200, and is used to make the first mounting platform 100 and the second mounting platform 200 approach or move away from each other along the X axis. The angle adjustment platform 400 is mounted on the second mounting platform 200, and the angle adjustment platform 400 is detachably connected to the component to be measured, and is used to drive the component to be measured to rotate around the Y axis and around the X axis; wherein, the X axis, the Y axis, and the Z axis are perpendicular to each other.
[0057] In this embodiment, by providing a first mounting platform 100 that can drive the black body to move along the Z-axis, the relative height between the black body and the test site of the component under test can be adjusted, ensuring that the identification distance is tested on the premise that the black body and the test site are at the same height. By providing a second mounting platform 200 along the X-axis, and connecting the second mounting platform 200 to the component under test through an angle adjustment platform 400, and combining with the provided distance adjustment platform 300, the first mounting platform 100 and the second mounting platform 200 can be moved closer to or away from each other along the X-axis through the distance adjustment platform 300 to adjust the distance between the black body and the component under test along the X-axis, realizing the test of the identification distance of the component under test along the X-axis. By providing an angle adjustment platform 400 detachably connected to the component under test, and the angle adjustment platform 400 can drive the component under test to rotate around the Y-axis and around the X-axis, the angle of the component under test can be adjusted. Combining with the first mounting platform 100, the second mounting platform 200 and the distance adjustment platform 300, the measurement of the identification distance of the component under test at different angles can be realized, the measurement of the identification distance of different test sites of the component under test can be realized, and the three-dimensional test of the component under test can be realized.
[0058] Existing test fixtures capable of three-dimensional testing usually rely on high-precision structural components and high-precision motors to achieve, which not only makes the structure of the test fixture complex, but also has a high cost. The complex structure will also bring manufacturing tolerances, and the manufacturing tolerances will affect the accuracy of the test results. Using the test fixture of this embodiment can not only achieve three-dimensional testing, but also compared with the existing test fixtures capable of three-dimensional testing, the structure of the test fixture of this embodiment is simpler, the test errors caused by manufacturing tolerances can be avoided, and the accuracy of the test results can be improved.
[0059] It can be understood that the angle adjustment platform 400 is detachably connected to the component under test, which is convenient for replacing the component under test.
[0060] It can be understood that the Z-axis is parallel to the Z direction, and the Z direction can be Figures 1 to 3 the vertical direction in Figures 1 to 3 i.e., the up and down direction; the X-axis is parallel to the X direction, and the X direction can be
[0061] the horizontal direction in
[0062] It can be understood that the black body can absorb all the energy of any wavelength radiated onto its surface at any temperature.
[0063] In the related art, PIR is usually used in combination with a Fresnel lens when in use, such as Figure 6As shown, when testing the PIR, it is usually the PIR equipped with a Fresnel lens that is tested. Since the recognition distances in different angular regions of the Fresnel lens are inconsistent, it is necessary to test the recognition distances in different angular regions of the Fresnel lens.
[0064] To achieve the test of recognition distances at different angles, taking the front view of the Figure 7 Fresnel lens as an example, five test sites are selected to be tested using the test tooling of this embodiment. Among them, test site 1 and test site 2 are symmetric about the Y-axis, test site 3 and test site 4 are symmetric about the Z-axis, and O is the coordinate origin.
[0065] The test process of the recognition distance of test site O includes:
[0066] First, install the component to be tested on the angle adjustment platform 400. By adjusting the first installation platform 100, make the black body and test site O at the same height position, and ensure that the black body is horizontally facing test site O. Then, fix the angle adjustment platform 400. As Figure 2 shown, by adjusting the distance adjustment platform 300, make the first installation platform 100 carry the black body approach the component to be tested along the X-axis. Specifically, the black body approaches the component to be tested from the distant position a. When it moves to position b and triggers the PIR of the component to be tested, stop moving, and record the distance L between the black body and the PIR. At this time, L is the farthest recognition distance of test site O of the Fresnel lens on the X-axis.
[0067] The test process of the recognition distances of test site 1 and test site 2 includes:
[0068] Taking Figure 8 shown as an example, the recognition distances of test point 1 and test point 2 are the farthest recognition distances at angles θ1 and -θ1.
[0069] As Figure 5 shown, install the component to be tested on the angle adjustment platform 400. By adjusting the angle adjustment platform 400, make the component to be tested rotate downward by θ1 with the Y-axis as the rotation axis. At this time, keep the angle and height of the angle adjustment platform 400 unchanged, adjust the first installation platform 100, and make the height of the black body consistent with that of test site 2. Then, as Figure 3 shown, adjust the distance between the first installation platform 100 and the second installation platform 200 through the distance adjustment platform 300. Specifically, the black body approaches the component to be tested from the distant position a. When it moves to position b and triggers the PIR of the component to be tested, stop moving, and record the distance L1 between the black body and the PIR. At this time, L1 is the farthest recognition distance at test site 2 of the Fresnel lens.
[0070] Similarly, by adjusting the angle adjustment platform 400 to rotate the element under test upward by θ1 with Y as the rotation axis, the test site 1 is tested at this time. The operation of the farthest recognition distance from the test site 2 is the same, and the farthest recognition distance of the test site 1 can be tested and obtained.
[0071] The test process of the recognition distance between the test site 3 and the test site 4 includes:
[0072] As Figure 9 shown in (a) therein, since the Y-axis where the test site 3 and the test site 4 are located is perpendicular to the Z-axis where the test site 1 and the test site 2 are located, the angle adjustment platform 400 can be used to drive the element under test to rotate 90° with the X-axis as the rotation axis at this time. Since the Fresnel lens is hemispherical, after rotating 90°, the test site 3 and the test site 4 are located on the Z-axis of the test fixture, as Figure 9 shown in (b) therein. After that, the test method is the same as that of the test point 1 and the test point 2. Taking the test of the farthest recognition distance of the test site 3 as an example: by adjusting the angle adjustment platform 400 to rotate the element under test downward by θ2 angle with the Y-axis as the rotation axis, at this time, keep the angle and height of the angle adjustment platform 400 unchanged, adjust the first installation platform 100, and make the height of the black body consistent with that of the test site 3. Then, adjust the distance between the first installation platform 100 and the second installation platform 200 through the distance adjustment platform 300. Specifically, the black body approaches the element under test from the distant position a. When it moves to the position b, it triggers the PIR of the element under test and stops moving. Record the distance L3 between the black body and the PIR. At this time, L3 is the farthest recognition distance at the test site 3 of the Fresnel lens.
[0073] It can be understood that by testing the maximum recognition distance of different angular regions of the Fresnel transparency, the detection range of the Fresnel lens in the horizontal direction can be obtained, as Figure 10 shown. The detection range of the Fresnel transparency in the vertical direction can also be obtained, as Figure 11 shown.
[0074] As Figure 4 and Figure 5 shown, in some embodiments of the present invention, the angle adjustment platform 400 includes a first angle adjustment component 410 and a second angle adjustment component 420. The first angle adjustment part is used for detachably connecting with the element under test and driving the element under test to rotate around the Y-axis; the installation end of the second angle adjustment component 420 is connected to the second installation platform 200, and the driving end of the second angle adjustment component 420 is connected to the first angle adjustment component 410, and is used for driving the element under test to rotate around the X-axis through the first angle adjustment component 410.
[0075] In this embodiment, the first angle adjustment component 410 can drive the element under test to rotate downward or upward with the Y-axis as the rotation axis. By setting the second angle adjustment component 420, the entire first angle adjustment component 410 can be driven to flip with the X-axis as the rotation axis, thereby driving the element under test to flip with the X-axis as the rotation axis, facilitating the adjustment of the rotation angle of the element under test according to actual needs.
[0076] As Figure 4 and Figure 5 shown, further, the rotation central axis of the driving end of the second angle adjustment component 420 is parallel to the X-axis, simplifying the structure of the second angle adjustment component 420.
[0077] Specifically, the second angle adjustment component 420 includes a second angle adjustment assembly 421 and a rotating shaft 422; the mounting end of the second angle adjustment assembly 421 is mounted on the second mounting platform 200, and the driving end of the second angle adjustment assembly 421 is connected to one end of the rotating shaft 422, and the other end of the rotating shaft 422 is connected to the first angle adjustment component 410, and the rotation central axis of the rotating shaft 422 is parallel to the X-axis. By providing the coaxially arranged second angle adjustment assembly 421 and the rotating shaft 422, and the rotation central axes of both are parallel to the X-axis, on the one hand, the rotating shaft 422 can realize the connection between the second angle adjustment assembly 421 and the first angle adjustment component 410, and on the other hand, a simple driving structure can be used to realize the rotation of the element under test around the X-axis.
[0078] Specifically, the second angle adjustment assembly 421 can be a fourth motor. Preferably, the fourth motor can be a servo motor. The rotation central axis of the fourth motor is parallel to the X-axis, and the driving end of the fourth motor is connected to the first angle adjustment component 410 through the rotating shaft 422.
[0079] As Figure 4 shown, further, the first angle adjustment component 410 includes a rotating member 411 and a first angle adjustment assembly 412. The rotating member 411 is used for detachably connecting with the element under test, facilitating the replacement of the element under test. The mounting end of the first angle adjustment assembly 412 is connected to the second angle adjustment component 420, and the driving end of the first angle adjustment assembly 412 is connected to the rotating member 411, and is used to drive the element under test to rotate around the Y-axis through the rotating member 411. Specifically, the mounting end of the first angle adjustment assembly 412 is connected to the end of the rotating shaft 422 far from the second angle adjustment assembly 421, and the driving end of the first angle adjustment assembly 412 is connected to the rotating member 411. The first angle adjustment assembly 412 can drive the element under test to rotate upward or downward with the Y-axis as the rotation axis through the rotating member 411.
[0080] Further, several teeth are formed on one side of the rotating member 411 facing the driving end of the first angle adjusting assembly 412, and the several teeth are arranged at intervals around the rotation center of the ring-shaped rotating member 411; the driving end of the first angle adjusting assembly 412 is meshed and connected with the teeth. The connection between the rotating member 411 and the first angle adjusting assembly 412 is realized in a meshing connection manner, which simplifies the driving structure.
[0081] Specifically, the rotating member 411 includes an arc-shaped rotating plate, teeth are formed on the convex surface of the arc-shaped rotating plate, and the groove of the arc-shaped rotating plate is used for installing the element to be measured. The driving end of the first angle adjusting assembly 412 is meshed and connected with the teeth of the arc-shaped rotating plate.
[0082] As Figure 4 shown, further, the first angle adjusting assembly 412 includes a connecting member 4121 and a first angle adjusting member 4122. The connecting member 4121 is connected to the driving end of the second angle adjusting member 420, and the connecting member 4121 is provided with an angle scale disk, and the center of the angle scale disk is located on the rotation axis of the rotating member 411. By providing the connecting member 4121, on the one hand, the rotation of the rotating member 411 can be realized, and on the other hand, the rotation angle of the rotating member 411 can be visually seen. The mounting end of the first angle adjusting member 4122 is connected to the connecting member 4121, and the driving end of the first angle adjusting member 4122 is meshed and connected with the rotating member 411 to drive the rotating member 411 to rotate around the Y axis. The first angle adjusting member 4122 provides power for the rotating member 411 to rotate upward or downward with the Y axis as the rotation axis.
[0083] As Figure 4 shown, specifically, along the Y axis, the connecting member 4121 is arranged on one side of the arc-shaped rotating plate, and angle scale lines are arranged around the convex surface of the arc-shaped rotating plate on the connecting member 4121. The first angle adjusting member 4122 includes a first angle driving member and a driving gear; the mounting end of the first angle driving member is mounted on the side of the connecting member 4121 away from the arc-shaped rotating plate, the driving gear is arranged on the side of the connecting member 4121 facing the arc-shaped rotating plate, the driving end of the first angle driving member is connected to the driving gear for driving the driving gear to rotate with the Y axis as the rotation axis, and the driving gear is also meshed with the teeth on the convex surface of the arc-shaped rotating plate, thereby driving the element to be measured to rotate with the Y axis as the rotation axis.
[0084] Specifically, the first angle driving member can be a fifth motor, preferably, the fifth motor is a servo motor. The rotation axis of the driving end of the fifth motor is parallel to the Y axis.
[0085] As Figures 1 to 3As shown in the figure, in a specific embodiment of the present utility model, the test tooling further includes a chassis 500; the first mounting platform 100, the second mounting platform 200 and the distance adjustment platform 300 are all mounted on the chassis 500. By providing the chassis 500, the first mounting platform 100, the second mounting platform 200 and the distance adjustment platform 300 can be integrated, facilitating the handling and movement of the test tooling. In addition, the chassis 500 also provides mounting positions for the first mounting platform 100, the second mounting platform 200 and the distance adjustment platform 300.
[0086] As Figures 1 to 3 shown in the figure, in a specific embodiment of the present utility model, the first mounting platform 100 includes a first platform 110 and a first platform drive assembly 120; the first platform 110 is used to connect with the black body, and the first platform drive assembly 120 is connected to the first platform 110 and is used to drive the first platform 110 to reciprocate along the Z-axis to adjust the relative height between the black body and the element under test.
[0087] In some embodiments, the first platform drive assembly 120 can be a first electric push rod. The first electric push rod expands and contracts along the Z-axis. The mounting end of the first electric push rod is mounted on the chassis 500, and the drive end of the first electric push rod is connected to the first platform 110.
