[0002] The application scenarios of lens modules are quite extensive, such as automobiles, mobile phones, surveillance, etc. In addition to the lens-related parameters, another important performance indicator of the lens module is the anti-shake performance. For example, most of the lenses currently used on mobile phones already have anti-shake functions, and the lenses on cars also have some requirements for this.

[0003] Before the lens module leaves the factory, it needs to be tested for anti-shake function. It is only allowed to leave the factory after meeting the standards. Therefore, professional testing equipment is needed to test the lens module.

[0004] At present, the testing equipment for lens modules in manufacturers has a complex structure and requires a lot of test data, which results in a large workload and makes it impossible to make a preliminary judgment on a lens module quickly and easily. Utility Model Content

[0014] A support frame, wherein grooves are formed on both sides of the support frame to form the guide grooves, and the support frame is slidably disposed in the working area;

[0015] A plurality of guide rails are arranged parallel to each other on the bottom surface of the working area.

[0016] Optionally, the guide rail includes a high-frequency rail, a low-frequency rail, a high-amplitude rail and a low-amplitude rail.

[0017] Optionally, a plurality of light sources are provided at one end of the working area, and each of the light sources corresponds to one of the guide rails.

[0018] Optionally, a slide groove is respectively provided at both ends of the working area, and one of the slide grooves passes through the end of the working area; both ends of the support frame are respectively slidably arranged in the slide grooves, and one end of the support frame passes through the slide groove.

[0019] Optionally, there is a gap between two ends of the guide rail and two ends of the working area.

[0035] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1-Figure 4 , an anti-shake test device for a lens module comprises a working area 1, a guide groove 2, a guide rail 3, a support plate 4, a slider 5, a roller 6, a bracket 7 and a motor 8. Specifically, the working area 1 is surrounded by a square frame, and a bottom plate is present on the bottom surface of the frame.

[0038] A guide rail 3 is provided on the bottom surface of the working area 1, and the top surface of the guide rail 3 is an undulating wave structure. A guide groove 2 is provided on both sides of the working area 1, and the opening sides of the two guide grooves 2 face upward, and a slider 5 is slidably provided inside the two guide grooves 2.

[0039] The two sides of the support plate 4 are respectively connected to the tops of the two sliders 5, so that the support plate 4 is slidably connected to the guide groove 2. A bracket 7 is fixedly connected to the middle of the bottom surface of the support plate 4, and a roller 6 is rotatably connected to the bottom end of the bracket 7. The axis of the roller 6 is arranged in the horizontal direction, and the wheel surface of the roller 6 is located on the guide rail 3.

[0040] The motor 8 is connected to the support plate 4, and the output shaft of the motor 8 is dynamically connected to one end of the roller 6 shaft. The motor 8 is used to drive the roller 6 to rotate continuously, and the motor 8 can drive the roller 6 to rotate forward or reverse.

[0041] During the test, the engineering prototype is first installed on the top surface of the support plate 4 and adjusted to the camera state, and then the motor 8 is powered on, and the motor 8 directly drives the roller 6 to rotate, thereby driving the support plate 4 to move in the guide groove 2.

[0042] Since the roller 6 moves on the guide rail 3 at the bottom of the working area 1 and the top surface of the guide rail 3 is a wavy structure, the guide rail 3 will cause the roller 6 and the support plate 4 to vibrate up and down.

[0043] In this embodiment, the anti-shake performance of the lens module is tested by continuous vibration, so that the anti-shake test of the lens module can be performed simply and quickly, so as to make a preliminary judgment on the anti-shake performance of the lens module.

[0044] In one specific embodiment:

[0045] The testing device further comprises a support frame 10 , both ends of which are slidably disposed at both ends of the working area 1 (ie, the inner sides of both ends of the frame), and both sides of the support frame 10 respectively have a concave structure to form a guide groove 2 .

[0046] A plurality of guide rails 3 are arranged in parallel on the bottom surface of the working area 1 , and the wavelengths and amplitudes of the waves on the top surfaces of all guide rails 3 are different.

[0047] Preferably, the guide rail 3 includes a high-frequency rail, a low-frequency rail, a high-amplitude rail and a low-amplitude rail. Meanwhile, on the same guide rail 3, waveforms in different areas may be different.

[0048] In this embodiment, the guide groove 2 is set on the support frame 10 and the support frame 10 can slide in the working area 1, thereby changing the guide rail 3 in contact with the roller 6, and the wavy structures on the top surfaces of all guide rails 3 are different, so that during the testing process, the anti-shake performance of the lens module can be tested according to different vibration states.

[0049] In another specific embodiment:

[0050] A plurality of light sources 11 are arranged at one end of the working area 1, and each light source 11 is arranged corresponding to a guide rail 3, so that during testing, the lens module can be photographed facing the light source 11, and the anti-shake performance of the lens module can be preliminarily judged with the light source 11 as a reference.

[0051] In another specific embodiment:

[0052] A slide groove is provided at each of the two ends of the inner side of the frame, and one of the slide grooves passes through the end of the frame (i.e., a slide groove is provided at each of the two ends of the working area 1, and one of the slide grooves passes through the end of the working area 1). The two ends of the support frame 10 are slidably disposed in the two slide grooves, and one end of the support frame 10 passes through the slide groove that passes through the end of the working area 1.

[0053] In this embodiment, by providing a slide groove and passing one end of the support frame 10 through the slide groove, the position of the support plate 4 can be conveniently adjusted through the end of the support frame 10, so that the roller 6 can conveniently move on different guide rails 3.

[0054] In another specific embodiment:

[0055] There is a distance between the two ends of the guide rail 3 and the two ends of the working area 1 . This structure can prevent the guide rail 3 from hindering the roller 6 when the roller 6 moves between different guide rails 3 .

[0056] In another specific embodiment:

[0057] A guide hole is provided at both ends of the top surface of each slider 5, and a guide rod 12 is slidably provided in each of the two guide holes, and the top ends of the two guide rods 12 are fixedly provided on the bottom surface of the support plate 4. At the same time, a spring 13 is sleeved on each guide rod 12, so that the top end of the spring 13 abuts against the bottom surface of the support plate 4, and the bottom end of the spring 13 abuts against the top surface of the slider 5.

[0058] In this embodiment, a guide hole is provided on the slider 5, and a guide rod 12 is slidably provided in the guide hole, so that when the roller 6 drives the support plate 4 to move, the support plate 4 will not tilt forward or backward. By providing a spring 13, the support plate 4 has a certain buffering effect during the vibration process, so that the state of a human body holding a camera device to shoot can be simulated, and at the same time, hard impact can be prevented from causing damage to the engineering prototype or lens module.

[0059] In another specific embodiment:

[0060] The motor 8 is arranged on the bottom surface of the support plate 4 through a U-shaped connecting piece 14, the motor 8 is located in the middle of the connecting piece 14, and the two ends of the connecting piece 14 are connected to the support plate 4. The output shaft of the motor 8 is connected to the rotating shaft of the roller 6 through a pair of gears. A counterweight block 9 is arranged on the bottom surface of the support plate 4, and the counterweight block 9 and the motor 8 are respectively located on both sides of the roller 6.

[0061] In this embodiment, the connecting member 14 provides a support point for the installation of the motor 8, and the counterweight block 9 is provided to balance the gravity on both sides of the support plate 4 to prevent the support plate 4 from tilting.

[0062] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
