Description

A positioning device for assembling optical lenses Technical Field

[0001] This utility model relates to the field of optical lens technology, and more specifically, to a positioning device for assembling optical lenses. Background Technology

[0002] Optical lenses are essential components in machine vision systems, directly affecting image quality and the implementation and effectiveness of algorithms. Optical lenses can be classified by focal length into short focal length lenses, medium focal length lenses, and long focal length lenses; by field of view into wide-angle lenses, standard lenses, and telephoto lenses; and by structure into fixed aperture fixed focal length lenses, manual aperture fixed focal length lenses, automatic aperture fixed focal length lenses, manual zoom lenses, automatic zoom lenses, automatic aperture motorized zoom lenses, and motorized triple-variable (aperture, focal length, and focus are all variable) lenses, etc.

[0003] In the prior art, the positioning effect of the optical lens assembly positioning device is poor. When assembling the lens, it is necessary to place each component of the lens into the lens barrel and then connect the pressure ring to the lens barrel to realize the assembly of the optical lens. However, during assembly, it cannot be guaranteed that the lens will fall accurately to the bottom of the lens barrel, which affects the assembly quality of the lens.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] In view of the problems in the related technologies, this utility model proposes a positioning device for assembling optical lenses to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A positioning device for assembling an optical lens includes an assembly table. A lead screw is installed in the inner cavity of the assembly table. A servo motor is mounted on one side of the top of the assembly table, and the output shaft of the servo motor is connected to the lead screw. A guide block is connected to the lead screw, and a positioning mechanism is connected to the guide block. A mounting base is located at the center of the top of the assembly table, and a vibration motor is mounted on the mounting base. A positioning plate is connected to the top of the mounting base, and a placement groove is provided on the positioning plate. A support frame is fixedly connected to the edge of the assembly table, and a hydraulic cylinder is mounted on the support frame. A pressure plate is connected to the output end of the hydraulic cylinder. A camera is located at the center of the pressure plate, and a clamping block is located at the bottom of the pressure plate.

[0008] Preferably, the lead screw is provided with two sections of threads with opposite directions, and the guide blocks are symmetrically arranged on the two sections of threads.

[0009] Preferably, the positioning mechanism includes a sliding frame, a connecting rod, a limiting block, a return spring, and a clamping plate. One end of the connecting rod passes through the sliding frame and is fixedly connected to the limiting block, while the other end of the connecting rod is fixedly connected to the clamping plate. The return spring is sleeved on the outside of the connecting rod.

[0010] Preferably, the positioning mechanism is symmetrically arranged on both sides of the positioning plate, and a semi-circular clamping groove is provided on the opposite side of the clamping plate.

[0011] Preferably, the reset spring is disposed between the clamping plate and the sliding frame, and a rubber pad is provided on the inner side of the clamping plate.

[0012] Preferably, the pressure plate is positioned above the positioning plate, and the diameter of the pressure plate is the same as that of the placement groove.

[0013] Preferably, the clamping block is L-shaped and is positioned at an equal angle at the bottom edge of the pressure plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When assembling the optical lens, the lens barrel is placed in the placement slot of the positioning plate. The servo motor drives the lead screw to rotate, which causes the guide block to move the positioning mechanism. The clamping plate of the positioning mechanism is placed on the outside of the lens barrel, so that the clamping plate forms a cylindrical structure. When assembling the lens, the lens can be placed into the lens barrel through the round hole in the middle of the clamping plate, which facilitates lens assembly and makes operation convenient.

[0016] 2. By using a vibration motor, when placing the lens components into the lens barrel, the camera observes whether the components are neatly arranged. If the lens is misaligned, the vibration motor drives the mounting base and positioning plate to vibrate, so that the lens can fall accurately into the lens barrel, improving the assembly efficiency of the lens.
