Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor testing lenses, in particular to a lens structure used for motor testing. Background Art
[0002] Optical image stabilization technology monitors the displacement information of the body's shaking and allows the anti-shake module to move in the opposite direction to offset the shaking, thereby effectively suppressing the impact of shaking on mobile phone imaging. Since 2020, different optical image stabilization solutions have been applied in the camera technology of major mainstream mobile phone manufacturers, including lens OIS image stabilization, sensor OIS image stabilization, and floating image stabilization. Lens OIS image stabilization is a relatively common image stabilization technology in various imaging devices.
[0003] The lens module is designed to be movable, or a movable lens that uses magnetic suspension is added to the lens module. The movable lens / lens cooperates with the mobile phone shaking data obtained by the gyroscope, and is driven by the voice coil motor or memory metal mechanical structure to move in the opposite direction to compensate for the light path affected by the body shaking, so that the light after shaking can still fall on the original position, which can bring more stable and clear imaging effects.
[0004] Currently, the test of autofocus motors requires screwing a threaded lens into the motor. The electrical characteristics of the motor are determined by testing the lens's motion trajectory and optical axis. All motors must be fully tested before shipment, and each motor must be screwed into the lens for testing. This is inefficient and may cause damage to the motor during the process.

[0016] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:
[0017] Please refer to Figure 1 and Figure 2 A lens structure for motor testing includes a reflective surface 10, a frame 20 and a plurality of elastic members 30. The reflective surface 10 is fixed to one side of the frame 20. The frame 20 has a plurality of slots 21 on its surface for placing the elastic members 30. The plurality of elastic members 30 are respectively disposed in the corresponding slots 21, and the elastic members 30 protrude from the outer surface of the frame 20.
[0018] During installation, first insert a plurality of elastic members 30 into the card slots 21 of the frame 20, and the elastic members 30 are squeezed by the card slots 21 to protrude from the outer surface of the frame 20, then fix the reflective surface 10 to one side of the frame 20, seal the elastic members 30 in the card slots 21, and then insert the entire lens into the lens barrel 40 of the test motor, and use the protruding parts of the elastic members 30 to contact the inner wall of the lens barrel 40 to achieve the purpose of interference fit, thereby achieving high test efficiency, zero damage to the lens barrel 40, ensuring that the lens barrel 40 and the lens are tightly fitted and clamped, and ensuring the test accuracy.
[0019] In the above scheme, the elastic member 30 is a tubular structure, so that when the elastic member 30 is installed or the lens is inserted into the lens barrel 40, it is ensured that the elastic member 30 can be squeezed and deformed and then restored. A plurality of convex strips 31 are provided on the surface of the elastic member 30. The convex strips 31 are used to create a deformation gap between the elastic member 30 and the card slot 21. The convex strips 31 can also be used to increase the strength of the elastic member 30, ensuring that the elastic member 30 can be restored and rebounded.
[0020] There are five elastic members 30 , which are spaced around the center of the frame 20 . When the lens is inserted into the lens barrel 40 , the elastic members 30 can be used to contact the inside of the lens barrel 40 from multiple directions, so that the force on the lens is balanced and the lens can be located in the center of the lens barrel 40 .
[0021] A bottom plate 22 is provided at the lower end of the skeleton 20, and a vent hole 221 is provided at the bottom plate 22 corresponding to the card slot 21. The vent hole 221 ensures that when the elastic member 30 is squeezed, the air in the center can be blown out through the vent hole 221. When resetting, the vent hole 221 can also be used for air suction. The bottom plate 22 can cooperate with the reflective surface 10 to restrict the elastic member 30.
[0022] The horizontal cross section of the card slot 21 is an arc-shaped structure, and the surface of the card slot 21 is provided with an opening for the elastic member 30 to protrude, and the opening is used to ensure that the elastic member 30 can protrude and contact the lens barrel 40, and the card slot 21 can ensure that the elastic member 30 is located in the frame 20. A positioning hole 23 is provided in the center of the frame 20, and a protrusion is provided on the side of the reflective surface 10 close to the frame 20. The positioning block and the protrusion make the installation of the reflective surface 10 and the frame 20 more accurate and quick.
[0023] The utility model provides a lens structure for motor testing. When installing, a plurality of elastic parts are first inserted into the card slots of a frame, and the elastic parts are squeezed by the card slots and protrude from the outer surface of the frame, and then a reflective surface is fixed to one side of the frame, the elastic parts are sealed in the card slots, and then the entire lens is inserted into the lens barrel of the test motor, and the protruding parts of the elastic parts are used to contact the inner wall of the lens barrel to achieve the purpose of interference fit, so as to achieve high test efficiency, zero damage to the lens barrel, ensure that the lens barrel and the lens are tightly fitted and clamped, and ensure the effect of test accuracy.
