It is widely used in computer vision, autonomous driving, robotics, navigation, and security monitoring. Before leaving the factory, monocular cameras undergo a series of tests. These tests involve fixing the camera to a fixture and including: moving it along a specific path and taking pictures at different positions during the movement; and rotating the camera to take pictures from different angles. Finally, the information captured during these processes is transmitted to a computer program for analysis.

[0003] In the related technical solution, the camera testing fixture includes a base plate, a cover plate, a carrier plate, and clamps. Both the cover plate and the carrier plate are vertically mounted on the base plate and are positioned opposite each other. Specifically, the carrier plate and the base plate are fixedly connected, while the cover plate is detachably mounted on the base plate. The cover plate has positioning holes for accommodating the product under test (e.g., a monocular camera), and clamps are located on both sides of the cover plate. In use, the cover plate is first removed from the base plate, then the product under test is inserted through the positioning holes in the cover plate, and then the cover plate is fixed to the base plate, connecting the product under test to the carrier plate. Finally, the clamps on both sides of the cover plate are used to press and fix the cover plate and the carrier plate together, and the base plate is then locked onto the testing equipment.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0062] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0063] Please refer to Figure 1 In the related technical solution, the camera testing fixture includes a base plate 10, a cover plate 20, a carrier plate 30, and clamps 40. The cover plate 20 and the carrier plate 30 are both vertically mounted on the base plate 10, and are positioned opposite each other. Specifically, the carrier plate 30 is fixedly connected to the base plate 10, the cover plate 20 is detachably mounted on the base plate 10, the cover plate 20 has positioning holes 21 for accommodating the product 1 to be tested, and clamps 40 are provided on both sides of the cover plate 20.

[0064] To use, first remove the cover plate 20 from the base plate 10. Then, please combine... Figure 2The product under test (DUT) 1 (e.g., a monocular camera) is inserted into the positioning hole 21 of the cover plate 20. Specifically, the outer shell 12 of the DUT 1 can be inserted into the positioning hole 21 and fixedly connected to the cover plate 20 to ensure the stability of the connection. After connection, the DUT 1 can communicate with the external connection display component 3 through the product probe 11. Then, the cover plate 20 is fixed to the base plate 10, connecting the DUT 1 to the carrier plate 30. Finally, please refer to... Figure 3 The cover plate 20 and the carrier plate 30 are pressed and fixed by the clamps 40 on both sides of the cover plate 20, and the base plate 10 is locked to the test equipment 2. Specifically, the base plate 10 is provided with multiple locking holes 50, and the base plate 10 can be locked to the test equipment 2 by fasteners such as bolts.

[0065] However, with the solution using the relevant technology, when the height of the product under test 1 (referring to the length perpendicular to the cover plate 20) changes, since the relative distance between the cover plate 20 and the carrier plate 30 is fixed, the camera test fixture may not be able to press the product under test 1 tightly, thus affecting the accuracy of the test results.

[0066] In view of this, the present application aims to provide a camera testing fixture, which, by setting a first elastic element between the pressure head cover plate and the pressure head, allows the pressure head to move up and down based on the height of the product under test, better adapting to products under test of different heights, ensuring that the fixture can press the product under test firmly, thereby ensuring the accuracy of the test results.

[0067] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0068] Please refer to Figures 4-17 This embodiment provides a camera testing fixture, including:

[0069] A cover plate 100 is provided with at least one product through hole 110. Exemplarily, the cover plate 100 may be generally flat, and the projection of the product through hole 110 in a plane parallel to the cover plate 100 may be square, circular, etc. The product through hole 110 is adapted to the shell of the product under test (e.g., a monocular camera) for the product under test to pass through, and the specific shape of the product through hole 110 may be set based on the shell shape of the product under test.

[0070] A carrier plate 200 is disposed opposite to a cover plate 100, for example, they can be stacked. The carrier plate 200 has at least one product mounting groove 210, which corresponds to a product through hole 110. Exemplarily, the carrier plate 200 can also be generally flat, with the product mounting groove 210 located on the side of the carrier plate 200 facing the cover plate 100, and the shape of the product mounting groove 210 can be adapted to the shape of the product to be tested.

[0071] At least two sets of snap-fit ​​assemblies 300 are respectively disposed on opposite sides of the cover plate 100. The snap-fit ​​assemblies 300 are connected to the cover plate 100 and the carrier plate 200, and are used to snap the cover plate 100 onto the carrier plate 200, thereby realizing the quick installation and removal of the cover plate 100 and the carrier plate 200.

[0072] At least one pressure head assembly 400 is disposed within the product through hole 110 for pressing the product to be tested. Figure 6 As shown, the pressure head assembly 400 includes a pressure head cover plate 410, a pressure head 420, and a first elastic member 430. The pressure head cover plate 410 abuts against the cover plate 100, and the pressure head 420 is located within the product through hole 110. The two ends of the first elastic member 430 are respectively connected to the pressure head cover plate 410 and the pressure head 420. The pressure head 420 can move axially along the product through hole 110, allowing it to move up and down axially along the product through hole 110 according to the height of the product under test, thus enabling the camera testing fixture to adapt to various sizes of products under test.

[0073] As described above, this embodiment provides a first elastic element 430 between the pressure head cover plate 410 and the pressure head 420, allowing the pressure head 420 to move up and down based on the height of the product to be tested. This better adapts to products of different heights, ensuring that the fixture can press the product to be tested firmly, thereby ensuring the accuracy of the test results.

[0074] Please continue to refer to Figure 6 The pressure head 420 in this embodiment includes a pressure head body 421 and a flange 422. The flange 422 is disposed on the side of the pressure head body 421 near the pressure head cover plate 410. A limiting groove 111 is provided on the side wall of the product through hole 110, and the flange 422 is located in the limiting groove 111.

[0075] With the above structure, this embodiment can limit the movement range of the pressure head 420 by the cooperation of the flange 422 and the limiting groove 111. The pressure head 420 can be adjusted within the above range to adapt to products of different sizes.

[0076] In this embodiment, the pressure head 420 is a flexible pressure head, for example, it can be made of silicone material. Through the slight deformation generated by the flexible material, the pressure head 420 can better fit with the product under test, increase friction, and ensure that the product under test will not easily shake or shift during the test.

[0077] The pressure head assembly 400 may include a plurality of first elastic elements 430, which are evenly distributed between the pressure head cover plate 410 and the pressure head 420. For example, this embodiment may provide four first elastic elements 430, which are respectively located at the four corners of the pressure head cover plate 410, thereby ensuring the uniformity of the elastic force distribution.

[0078] Please continue to refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The latching assembly 300 of this embodiment includes at least one latch 310, and the latch 310 includes a first hook 311 and a second hook 312. The middle portion of the first hook 311 is rotatably connected to the cover plate 100; exemplarily, the cover plate 100 may be provided with a structure such as an adapter plate for mounting the latch 310, and the first hook 311 can be rotatably connected to the adapter plate via a pin or similar structure. The second hook 312 is disposed on the carrier plate 200; exemplarily, the second hook 312 can be fastened to the carrier plate 200 by fasteners such as bolts or screws.

[0079] A second elastic element 313 is provided between the cover plate 100 and the first hook 311. The second elastic element 313 abuts against the first end of the first hook 311, and the second end of the first hook 311 is used to engage with the second hook 312. By providing the second elastic element 313, an elastic force can be applied to the first end of the first hook 311, thereby ensuring the stability of the engagement between the first hook 311 and the second hook 312.

[0080] Preferably, the buckle assembly 300 of this embodiment includes at least two buckles 310. The first end of the first hook 311 is also provided with a connecting hole 3111. The buckle assembly 300 includes a connecting rod 320, with both ends of the connecting rod 320 connected to the connecting holes 3111 of the two first hooks 311 respectively. Through the above structure, this embodiment can achieve the linkage of each buckle 310 in the buckle assembly 300. When opening or locking the buckle assembly 300, only one buckle 310 needs to be operated, and the remaining buckles 310 can synchronously perform corresponding actions under the drive of the connecting rod 320.

[0081] Please continue to refer to Figure 9 and Figure 10In this embodiment, the product mounting slot 210 is further provided with at least one positioning component mounting hole 211, and a positioning component 220 is provided in the positioning component mounting hole 211. The positioning component 220 is used to connect with the positioning hole on the product under test. Specifically, the positioning component 220 includes a pin 221, and the end of the pin 221 facing away from the positioning component mounting hole 211 forms a guide portion 2211. The cross-sectional area of ​​the guide portion 2211 gradually decreases in the direction facing away from the positioning component mounting hole 211. With the above structure, this embodiment can achieve precise positioning with the product under test through the pin 221, and the guide portion 2211 can better adapt to the different tolerance dimensions of the positioning hole on the product under test.

[0082] Furthermore, the positioning component 220 in this embodiment also includes a sleeve 222, a third elastic element 223, and an elastic element mounting base 224. The elastic element mounting base 224 is disposed within the positioning component mounting hole 211, the pin 221 is located within the sleeve 222, the first end of the third elastic element 223 is connected to the elastic element mounting base 224, and the second end of the third elastic element 223 is connected to the pin 221. The third elastic element 223 can drive the pin 221 to float up and down along the axial direction of the sleeve 222. With the above structure, after the product under test is pressed by the pressure head assembly 400, the pin 221, due to its floating nature, will press against the positioning hole of the product under test, forming a tight fit, and the product under test is accurately positioned. When there are multiple products under test, the consistency of placement of multiple products under test is greatly improved, and the influence of tolerance is basically minimized.

[0083] Please continue to refer to Figure 4 , Figure 5 , Figure 9 and Figure 11 In this embodiment, the cover plate 100 has multiple product through holes 110, and the carrier plate 200 has multiple product mounting slots 210. Each product mounting slot 210 corresponds one-to-one with a product through hole 110, and each product through hole 110 contains a pressure head assembly 400. That is, this embodiment can simultaneously test multiple products under test, thereby saving testing time. For example, this embodiment can provide six product through holes 110, corresponding to six product mounting slots 210 and six pressure head assemblies 400, to simultaneously test six products under test, increasing testing efficiency by six times.

[0084] Please continue to refer to Figure 9 and Figure 12In this embodiment, the product mounting slot 210 is further provided with a probe assembly 230, which includes a first probe 231 and a probe mounting plate 232. The first probe 231 passes through the probe mounting plate 232. The product mounting slot 210 has a probe hole 212, and the first probe 231 corresponds to the probe hole 212. The probe mounting plate 232 is fixedly connected to the side of the product mounting slot 210 opposite to the cover plate 100. That is, in this embodiment, the first probe 231 can pass through the bottom wall of the product mounting slot 210 and be exposed within the product mounting slot 210. Figure 13 The first probe 231 can be connected to the product probe 11 on the product under test, thereby enabling communication with the product under test.

[0085] Please continue to refer to Figure 4 , Figure 5 and Figure 14 This embodiment also includes a base plate 500, on which a carrier plate 200 is disposed. A shunt plate 600 is also provided on the base plate 500, and the shunt plate 600 can be located at opposite ends of the base plate 500. At least one second probe 610 is provided on the shunt plate 600, and a first probe 231 is communicatively connected to the second probe 610. Exemplarily, the first probe 231 can be communicatively connected to the second probe 610 via a wiring harness or the like. With this structure, the probe connection position between the product under test and the testing equipment can be moved to the shunt plate 600, thereby facilitating communication with the testing equipment.

[0086] Please continue to refer to Figure 4 , Figure 5 , Figure 15 , Figure 16 and Figure 17 This embodiment also includes a robotic arm 700, located on the side of the base plate 500 opposite to the carrier plate 200. The robotic arm 700 has a third probe 710, which is communicatively connected to the second probe 610. In this embodiment, the communication connection between the robotic arm 700 and the product under test is achieved through the communication connection between the third probe 710 on the robotic arm 700 and the second probe 610 on the splitter plate 600. The robotic arm 700 can be a part of a camera testing fixture used to connect testing equipment.

[0087] Furthermore, the robotic arm 700 of this embodiment is also provided with at least one clamping component 720, and the base plate 500 is provided with at least one clamping hole 510. The clamping component 720 and the clamping hole 510 are detachably connected, thereby facilitating the improvement of the installation and disassembly efficiency of the robotic arm 700 and the base plate 500.

[0088] Specifically, such as Figure 17As shown, the clamping hole 510 in this embodiment includes a first hole segment 511 and a second hole segment 512 that are connected to each other. The diameter of the second hole segment 512 is larger than the diameter of the first hole segment 511.

[0089] The clamping assembly 720 includes a clamping body 721 and a clamping plug 722. The clamping plug 722 passes through the first hole section 511 and is located in the second hole section 512. The clamping plug 722 is provided with a plurality of clamping elements (not shown in the figure). The clamping elements can move radially along the clamping plug 722 to abut or separate from the second hole section 512.

[0090] In other possible implementations, such as Figure 4 and Figure 5 As shown, in this embodiment, the robotic arm 700 can be omitted, and the device can be directly connected to the external device via the base plate 500. Specifically, the base plate 500 is also provided with at least one positioning plate 520, which has at least one device connection hole 521. The external device can be connected to the device connection hole 521 to move the camera test fixture and complete the test.
