Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a shake-proof testing device. Background Technology
[0002] Optical image stabilization (OIS) works by using a floating lens to correct optical axis shift, effectively overcoming image blur caused by camera shake. With the rapid development of digital cameras and smartphones, optical image stabilization technology has been widely applied to electronic imaging devices such as mobile phones, tablets, and cameras, and image quality has become an important indicator of the performance of electronic imaging devices.
[0003] In the manufacturing process of electronic imaging equipment, optical image stabilization (OIS) testing of camera modules has become an essential step. Currently, OIS testing of camera modules is mainly conducted using OIS testing equipment. The product under test is fixed on the testing platform of the equipment, and then simulated shaking is performed via single-axis or multi-axis methods to mimic the shaking environment during camera module use, thereby testing the OIS performance. However, existing OIS testing equipment suffers from low testing efficiency, insufficient accuracy, and the inability to use a single device to test multiple products (such as mobile phones, tablets, action cameras, and automotive cameras), requiring the use of separate OIS testing equipment, resulting in high testing costs.

[0005] This application provides a shake stabilization testing device, comprising:
[0006] Base;
[0007] A rotating assembly includes a first rotating power component, a second rotating power component, a first rotating frame, and a second rotating frame. The first rotating power component is mounted on the base and connected to the first rotating frame, driving the first rotating frame to rotate around a first center line. The first rotating frame has a rotating cavity, and the second rotating frame is disposed within the rotating cavity. One end of the second rotating frame is rotatably connected to the first rotating frame, and the other end is connected to the second rotating power component, so that it swings relative to the first rotating frame around a second center line under the power of the second rotating power component. The second rotating power component is mounted on the first rotating frame and located within the rotating cavity. The second rotating frame has a placement cavity. The first center line intersects the second center line.
[0008] A fixture is located inside the placement cavity and connected to the second rotating frame. The fixture has multiple fixing holes spaced apart to fix different test frames onto the second rotating frame.
[0009] In one embodiment, a rotating shaft located on the opposite side of the second rotating power member is further included. The rotating shaft passes through the first rotating frame along the second center line and is rotatably connected to the second rotating frame. The rotating shaft and the second rotating power member are on the same horizontal line.
[0010] In one embodiment, the swing amplitude of the second rotating frame relative to the first rotating frame is within the following range: -6°≤S≤6°, where S is the swing amplitude of the second rotating frame relative to the first rotating frame.
[0011] In one embodiment, the first rotary power component is a first direct drive motor, and the second rotary power component is a second direct drive motor.
[0012] In one embodiment, the first rotating frame includes a first base plate and two first side plates symmetrically disposed on both sides of the first base plate. One end of each of the two first side plates is connected to both ends of the first base plate to form the rotating cavity. A first connecting plate is provided on the surface of the first base plate facing the base, and the first connecting plate is connected to the rotating disk of the first direct drive motor.
[0013] In one embodiment, one of the two first side plates has a first mounting hole on its inner side, and the end of the second direct drive motor facing the first side plate is fixed with a first mounting plate, and the first mounting plate has a second mounting hole that matches the first mounting hole.
[0014] In one embodiment, the second rotating frame includes a second base plate and two second side plates symmetrically arranged on both sides of the second base plate. One end of each of the two second side plates is connected to both ends of the second base plate to form the placement cavity. The second side plate located on the same side as the second direct drive motor is provided with a second connecting plate, which is connected to the rotating disk of the second direct drive motor.
[0015] In one embodiment, the fixture is mounted in the middle of the second base plate and is on the same straight line as the first direct drive motor.
[0016] In one embodiment, the base has a first fixing hole on its surface for mounting the first direct drive motor, and a second mounting plate is provided at one end of the first direct drive motor near the base. The second mounting plate has a second fixing hole that matches the first fixing hole.
[0017] In one embodiment, a handle is fixed to the surface of the base on which the first rotating power member is mounted.
[0018] The technical solutions provided in this application have the following advantages compared with the prior art:
[0019] A first rotating frame is connected to a first rotating power component, and the first rotating frame has a rotating cavity. A second rotating frame is then placed inside the rotating cavity. A fixture for connecting a test frame is then installed on the second rotating frame. When a product needs to be tested, the product is fixed on the corresponding test frame, and the test frame is connected to the fixture. Under the power of the first rotating power component, the first rotating frame is driven to rotate around a first center line, and under the power of the second rotating power component, it swings relative to the first rotating frame around a second center line, thereby causing the product under test to shake. This simulates the shaking environment of the product's camera module during use, enabling image stabilization testing. The testing efficiency is high, and the test results are accurate. Furthermore, by changing different test frames and fixtures, a single image stabilization testing device can be used to test multiple products, effectively saving testing costs. In addition, the anti-shake testing equipment adopts a method of nesting the second rotating frame inside the rotating cavity of the first rotating frame to form a two-degree-of-freedom rotational coupling, achieving a compact layout with axial stacking. This method occupies little space and can reduce the overall inertia during rotation, accurately simulating various shaking environments to meet the multi-dimensional anti-shake testing needs of the products under test.

[0034] Please refer to Figure 1 and Figure 2This application provides a stabilization testing device, which includes a base 10, a rotating assembly, and a fixture 60. The rotating assembly includes a first rotating power component 20, a second rotating power component 50, a first rotating frame 30, and a second rotating frame 40. The first rotating power component 20 is mounted on the base 10 and connected to the first rotating frame 30, driving the first rotating frame 30 to rotate around a first center line X. The first rotating frame 30 has a rotating cavity 90. The second rotating frame 40 is disposed within the rotating cavity 90, with one end rotatably connected to the first rotating frame 30 and the other end connected to the second rotating power component 50, so that it swings relative to the first rotating frame 30 around a second center line Y under the power of the second rotating power component 50. The second rotating power component 50 is mounted on the first rotating frame 30 and located within the rotating cavity 90. The second rotating frame 40 has a placement cavity 140. The first center line and the second center line intersect. The fixture 60 is located inside the placement cavity 140 and is connected to the second rotating frame 40. The fixture 60 has multiple fixing holes spaced apart to fix different test frames 150 onto the second rotating frame 40.
[0035] It should be noted here that "first centerline X" in the above refers to the centerline around which the first rotating frame 30 rotates (see details). Figure 1 The "X-ray" refers to the X-ray in the image, while the "second center line Y" refers to the center line around which the second rotating frame 40 rotates (see [reference] for details). Figure 1 (The Y-line in the middle).
[0036] The image stabilization testing equipment of this embodiment connects a first rotating frame 30 to a first rotating power component 20, and the first rotating frame 30 has a rotating cavity 90. A second rotating frame 40 is then placed inside the rotating cavity 90. A fixture 60 for connecting a test frame 150 is then installed on the second rotating frame 40. When a product needs to be tested, the product is fixed on the corresponding test frame 150, and the test frame 150 is connected to the fixture 60. Under the power of the first rotating power component 20, the first rotating frame 30 is driven to rotate around the first center line X, and under the power of the second rotating power component 50, it swings relative to the first rotating frame 30 around the second center line Y, thereby causing the product under test to shake. This simulates the shaking environment of the product's camera module during use, so as to test its image stabilization effect. The testing efficiency is high, the test results are accurate, and different test frames 150 can be connected to the fixture 60 to achieve the use of a single image stabilization testing equipment to test multiple products, which can effectively save testing costs. In addition, the anti-shake testing equipment adopts a method of nesting the second rotating frame 40 within the rotating cavity 90 of the first rotating frame 30 to form a dual-degree-of-freedom rotational coupling, achieving a compact layout with axial stacking. This method occupies little space and reduces the overall inertia during rotation, accurately simulating various shaking environments to meet the multi-dimensional anti-shake testing needs of the product under test.
[0037] In one embodiment, a rotating shaft 70 is also included, located on the opposite side of the second rotating power member 50. The rotating shaft 70 passes through the first rotating frame 30 along a second center line and is rotatably connected to the second rotating frame 40. The rotating shaft and the second rotating power member 50 are on the same horizontal line. That is, by setting the rotating shaft 70 on the first rotating frame 30 and then rotatably connecting the rotating shaft 70 to the second rotating frame 40, the second rotating frame 40 can be driven to swing relative to the first rotating frame 30 when the second rotating power member 50 rotates. In addition, the rotating shaft 70 and the second rotating power member 50 are symmetrically distributed on the same horizontal line to form a bidirectional rigid support structure, which counteracts the radial off-center load torque generated by unilateral drive, significantly reduces vibration and bearing wear during high-speed rotation, and improves dynamic stability.
[0038] Reference Figure 3In one embodiment, the swing amplitude S of the second rotating frame 40 relative to the first rotating frame 30 is between -6° and 6°. It should be noted that the swing amplitude S range includes the endpoints -6° and 6°. For ease of understanding, this embodiment defines the forward swing amplitude S of the second rotating frame 40 relative to the first rotating frame 30 as a positive amplitude, and the backward swing amplitude S of the second rotating frame 40 relative to the first rotating frame 30 as a negative amplitude. When the second rotating frame 40 overlaps with the first rotating frame 30, the swing amplitude S is 0°. Using this as a reference, if the second rotating frame 40 swings forward to its furthest position, the swing amplitude S of the second rotating frame 40 relative to the first rotating frame 30 is 6° (e.g., ...). Figure 3 As shown, when the second rotating frame 40 swings backward to its furthest position, the swing amplitude of the second rotating frame 40 relative to the first rotating frame 30 is -6°.
[0039] In one embodiment, the first rotating power component 20 is a first direct-drive motor, and the second rotating power component 50 is a second direct-drive motor. That is, in this embodiment, both the first rotating power component 20 and the second rotating power component 50 are direct-drive motors, enabling direct rotation of the first rotating frame 30 and the second rotating frame 40. This eliminates the intermediate losses of traditional transmission mechanisms (such as gears, belts, reducers, couplings, etc.), achieving zero-backlash power transmission, reducing mechanical complexity and failure rate, and eliminating problems such as gear wear and belt aging, thereby extending service life. Simultaneously, using direct-drive motors to directly power the first rotating frame 30 and the second rotating frame 40 makes the entire anti-shake testing equipment more compact and smaller in size. Furthermore, by eliminating the traditional gear transmission method, noise from gear meshing or belt wear can be avoided.
[0040] Reference Figure 4In one embodiment, the first rotating frame 30 includes a first base plate 31 and two first side plates 32 symmetrically arranged on both sides of the first base plate 31. One end of each of the two first side plates 32 is connected to one end of the first base plate 31 to form a rotating cavity 90. A first connecting plate 130 is provided on the surface of the first base plate 31 facing the base 10. The first connecting plate 130 is connected to the rotating disk of the first direct drive motor. In practical applications, the two first side plates 32 are integrally formed with the first base plate 31 to give the first rotating frame 30 a better rigid structure, so that a uniformly distributed rotational load can be obtained when it is driven to rotate, reducing the risk of vibration or off-center load during rotation, thereby affecting the accuracy of the test. In addition, by using the rigid connection between the first connecting plate 130 and the rotating disk of the first direct drive motor, the first direct drive motor can directly drive the first rotating frame 30 to rotate, which can eliminate the intermediate loss of the transmission mechanism (such as gears and belts), realize zero backlash power transmission, improve energy utilization and motion control accuracy, and at the same time reduce mechanical complexity and fixation rate.
[0041] In one embodiment, one of the two first side plates 32 has a first mounting hole on its inner side, and the end of the second direct drive motor facing the first side plate 32 is fixed with a first mounting plate 110, and the first mounting plate 110 has a second mounting hole 110a that matches the first mounting hole.
[0042] Reference Figure 5 In one embodiment, the second rotating frame 40 includes a second base plate 41 and two second side plates 42 symmetrically arranged on both sides of the second base plate 41. One end of each of the two second side plates 42 is connected to one end of the second base plate 41 to form a placement cavity 140. The second side plate 42 on the same side as the second direct drive motor is provided with a second connecting plate 120, which is connected to the rotating disk of the second direct drive motor. In practical applications, the two second side plates 42 are integrally formed with the second base plate 41 to give the second rotating frame 40 a better rigid structure, so that a uniformly distributed rotational load can be obtained when it is driven to rotate, reducing the risk of vibration or off-center load during rotation, thereby affecting the accuracy of the test. In addition, by using the rigid connection between the second connecting plate 120 and the rotating disk of the second direct drive motor, the second direct drive motor can directly drive the second rotating frame 40 to rotate, which can eliminate the intermediate loss of the transmission mechanism (such as gears and belts), realize zero backlash power transmission, improve energy utilization and motion control accuracy, and also reduce mechanical complexity and fixation rate.
[0043] In one embodiment, the fixture 60 is mounted in the middle of the second base plate 41 and is aligned with the first direct drive motor. Thus, after the test frame 150 is connected to the fixture 60, the test frame 150 is located in the middle of the second base plate 41, ensuring that the product under test experiences uniform force distribution during testing, reducing interference from lateral forces or torque, thereby minimizing interference from other factors on the test results and improving test accuracy.
[0044] In one embodiment, the base 10 has a first fixing hole on its surface for mounting the first direct drive motor. A second mounting plate 100 is provided at one end of the first direct drive motor near the base 10, and the second mounting plate 100 has a second fixing hole 100a that matches the first fixing hole. That is, when mounting the first direct drive motor on the base 10, the second mounting plate 100 at the end of the first direct drive motor near the base 10 is first placed on the base 10, at which point the second fixing hole 100a is aligned with the first fixing hole. Then, fasteners (such as locking bolts) are passed sequentially through the second fixing hole 100a and the first fixing hole, thereby detachably fixing the first direct drive motor to the base 10. This method is simple in structure and convenient for assembly and disassembly.
[0045] In one embodiment, a handle 80 is fixed to the surface of the base 10 on which the first rotating power member 20 is mounted, and the handle 80 is located on the periphery of the first rotating power member 20. Thus, the tester can lift the entire image stabilization testing device by gripping the handle 80 and pulling upwards, facilitating subsequent rapid transfer. It should be noted that the handle 80 and the base 10 can be separate components; that is, the base 10 and the handle 80 are manufactured separately, and then the handle 80 is fixed to the base 10 using fasteners (such as bolts). Alternatively, the handle 80 and the base 10 can be a single piece, i.e., the handle 80 and the base 10 are joined together using an injection molding process, thereby achieving greater structural strength.
[0046] To facilitate understanding of the working principle of the image stabilization testing equipment in this application, the following explanation uses the image stabilization performance test of a security product's camera module as an example:
[0047] Reference Figure 5 The test frame 150 for fixing security products is fixed to the fixture 60, and then the product 160 is fixed on the test frame 150. Then, under the power of the first rotating power component 20, the first rotating frame 30 is driven to rotate around the first center, and under the power of the second rotating power component 50, it swings around the second center line relative to the first rotating frame 30, thereby causing the product under test to shake, thus simulating the shaking environment of the product's camera module during use, so as to test its image anti-shake effect.
[0048] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
