Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera testing, in particular to a camera testing fixture. Background Art
[0002] Camera testing plays a vital role in ensuring product quality. Through camera testing, we ensure that the camera's image quality, performance stability, and functional integrity meet expected standards. A camera module is a complex system integrating optics, mechanics, electronics, software, and hardware. Advanced manufacturing processes require high coordination and technical mastery across all stages, making camera testing an integral part of advanced manufacturing.
[0003] Camera testing includes appearance testing, performance testing, stability testing, safety testing, functionality testing, network performance testing and durability testing. Among them, performance testing includes transmittance testing. At present, the transmittance testing of most cameras is completed manually. The transmittance testing is most effective in a sealed and lightless environment. Manual testing has poor sealing, resulting in large errors in the test results and low detection efficiency.
[0004] The patent number is CN201820842496.0, and the patent name is a camera test fixture. The patent discloses a fixture for testing the light transmittance of the camera. The camera is placed face up on a fixed clamp, and the light transmittance detection transmitter is used to emit detection light. The light transmittance receiver receives the detection light emitted by the light transmittance detection transmitter, thereby achieving automated detection of the camera. However, in this patent, the structure of the fixed clamp is fixed, and it can only clamp cameras of the same size repeatedly, and cannot clamp and detect cameras of other sizes. The scope of use is not wide and flexible. In order to ensure that the detection device is not light-transmitting, the patent uses structures such as moving rails, moving blocks, support platforms, detection vertical baffles, and rotating hand-pull plates to move the structure out of the detection frame and install the camera, and then move it back into the detection frame. The structure is relatively complex. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example 1
[0026] This embodiment provides a camera test fixture, including a camera 1, a fixture base 2, a clamping base 3, a detection frame 4 and a frame cover 5. Figure 1 As shown, the detection frame 4 is provided on the clamping seat 3 and is integrally formed with the clamping seat 3. The clamping seat 3 is provided above the fixture seat 2, and one side thereof is screwed to the corresponding side of the fixture seat 2. The screwing means that the clamping seat 3 can rotate around the part connected to the fixture seat 2, and the fixture seat 2 can be rotated to open the fixture seat 2, or it can be rotated to the fixture seat 2 to keep the interior of the fixture opaque. A square clamping groove 6 is provided in the middle of the clamping seat 3, and a clamping mechanism 7 is provided in the clamping groove 6. The camera 1 is placed in the middle of the clamping mechanism 7 and is clamped by the clamping mechanism 7. A movable detection mechanism 8 is provided in the detection frame 4, and a frame cover 5 is provided at the upper end of the detection frame 4 (the frame cover 5 is opened when the camera 1 is placed).
[0027] In this embodiment, a receiving groove 9 is provided on the fixture base 2 at a position corresponding to the clamping through groove 6 . A light-transmitting receiver 10 is provided in the receiving groove 9 . The light-transmitting receiver 10 is located below the camera 1 .
[0028] When using a camera test jig of this embodiment, the clamping seat 3 and the detection outer frame 4 are placed on the jig seat 2, the camera 1 is clamped by the clamping mechanism 7, and the frame cover 5 is covered on the detection outer frame 4 to ensure that the detection environment is not light-transmitting. The structure is simple, and the clamping mechanism 7 of the utility model can adapt to cameras 1 of different sizes, with a wide range of uses and high flexibility.
[0029] Example 2
[0030] The clamping mechanism 7 of this embodiment includes two clamping plates 71 symmetrically arranged on two opposite sides of the clamping slot 6 and two adjustment mechanisms arranged on the other opposite sides of the clamping slot 6. The two ends of each adjustment mechanism are connected to the corresponding ends of the two clamping plates 71, and the camera 1 is arranged between the two clamping plates 71.
[0031] The rest are the same as Example 1.
[0032] The adjustment mechanism of this embodiment can adjust the distance between the two clamping plates 71 according to the size of the camera 1, so that the clamping plates 71 can always stably clamp the camera 1. It is easy to use and highly flexible.
[0033] Example 3
[0034] Each adjustment mechanism of this embodiment includes a fixed block 72, two adjustment springs 73 and two sliding rods 74. Figure 2-4 As shown, the fixed block 72 is arranged in the middle of the side of the clamping groove 6 where the adjustment mechanism is located, and the two adjustment springs 73 are respectively arranged on both sides of the fixed block 72, and one end of each of them is connected to the fixed block 72, and the other end is respectively connected to the clamping plate 71 at the corresponding end; the two sliding rods 74 are respectively arranged on both sides of the fixed block 72, and one end of each of them is connected to the fixed block 72, and the other end passes through the clamping plate 71 at the corresponding end and is connected to the side of the clamping groove 6 at the corresponding end; the clamping plate 71 can slide on the sliding rod 74.
[0035] The adjustment mechanism further includes four limit blocks 75 , which are respectively arranged at the ends of the sliding rod 74 connected to the side of the clamping slot 6 , that is, the limit blocks 75 are arranged between the side of the clamping slot 6 and the clamping plate 71 .
[0036] The rest are the same as Example 2.
[0037] When placing the camera 1, the two clamping plates 71 are pulled toward both sides of the clamping slot 6 according to the elastic force of the adjusting spring 73, and the camera 1 is placed between the two clamping plates 71. Then, the elastic force of the adjusting spring 73 is used to make the two clamping plates 71 move toward each other to clamp the camera 1 placed between the clamping plates 71, thereby adapting to cameras 1 of different sizes.
[0038] Example 4
[0039] In this embodiment, a receiving plate 76 is extended from the bottom of the two clamping plates 71 in a direction toward each other, and the camera 1 is placed on the receiving plate 76 .
[0040] The rest is the same as Example 3.
[0041] The setting of the receiving plate 76 in this embodiment can place the camera 1 more stably, and avoid the unstable camera 1 from falling and affecting the detection of the camera 1.
[0042] Example 5
[0043] The mobile detection mechanism 8 of this embodiment includes a lifting mechanism, a limiting mechanism and a detection mechanism. Figure 5 As shown, the lifting mechanism and the limiting mechanism are respectively located on both side surfaces inside the detection outer frame 4. The lifting mechanism includes a motor 81, a lifting screw 82 and a rotating connector 83. The motor 81 and the rotating connector 83 are both arranged on the inner side of the detection outer frame 4, and the rotating connector 83 is located above the motor 81. The lower end of the lifting screw 82 is transmission-connected to the motor 81, and the upper end is rotationally connected to the rotating connector 83. One end of the detection mechanism is transmission-connected to the lifting screw 82, and the other end is vertically slidingly connected to the limiting mechanism.
[0044] The rest are the same as Example 1.
[0045] When this embodiment is in use, the motor 81 is started to rotate the lifting screw 82. Since the other end of the detection mechanism is horizontally limited in the limiting mechanism, the rotation of the lifting screw 82 can drive the detection mechanism connected to it to rise and fall, thereby detecting the camera 1 at different distances.
[0046] Example 6
[0047] The detection mechanism of this embodiment includes a support link 84 and a light transmission detection emitter 85. One end of the support link 84 is transmission-connected to the lifting screw 82, and the other end is vertically slidably connected to the limiting mechanism. The light transmission detection emitter 85 is arranged in the middle of the support link 84.
[0048] The limiting mechanism of this embodiment includes a limiting frame 86. The limiting frame 86 is hollow and has a sliding groove 87 on the side close to the supporting link 84 to accommodate the supporting link. Figure 6 As shown, a limiting slider 88 is provided at the end of the support link 84 close to the limiting frame 86 . The limiting slider 88 is limited in the limiting frame 86 and can slide up and down in the limiting frame 86 .
[0049] The rest are the same as Example 5.
[0050] In this embodiment, the rotation of motor 1 drives support link 84 to rise and fall, thereby driving light transmission detection generator 85 to perform detection at different distances from camera 1. As support link 84 rises and falls on lifting screw 82, it drives limit slider 88 to move up and down within limit frame 86. Because limit frame 86 limits limit slider 88 in the horizontal direction, support link 84 can be displaced on lifting screw 82 due to the rotation of lifting screw 82.
[0051] In this utility model Figure 1-4 The clamping mechanism 7 is shown in the figure and the camera 1 is not provided. Figure 5 The camera 1 is shown in FIG. 1 , which is located between two clamping plates 71 and above the light-transmitting receiver 10 .
[0052] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary engineering technicians in this field should fall within the scope of protection of the present invention. The technical contents requested for protection of the present invention have been fully recorded in the technical requirements.
