Technical Field

[0001] This invention relates to the field of automation equipment technology, and more specifically to a high-precision coupling device for external lenses. Background Technology

[0002] Camera lenses are crucial components of a camera, directly impacting image quality. Lens quality is also a significant factor in differentiating camera types and grades. Lens manufacturing involves multiple processes, with the coupling connection between the lens and lens housing being paramount. Existing lens coupling processes suffer from the following problems: 1. Lens misalignment during clamping and mounting leads to poor coupling. 2. High precision is required for lens coupling, and inaccurate positioning can cause coupling misalignment. 3. The coupling equipment lacks three-axis automated control, increasing unnecessary manual labor costs. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention provides a high-precision coupling device for external lenses. This device is rationally designed and can effectively solve the problem of lens misalignment during the coupling process. It also effectively solves the problem of excessively high labor costs caused by the inability to achieve three-axis automation.

[0004] The above-mentioned objective of the present invention is achieved through the following technical solution:

The calibration mechanism and the second slide rail assembly are mounted on the operating frame. The dispensing mechanism is slidably mounted on the second slide rail assembly and performs radial reciprocating motion relative to the vertical direction of the second slide rail assembly. The coupling worktable is mounted on the base and located below the working module. The coupling worktable includes a housing locking module, a lens coupling platform, and an axis positioning platform. The axis positioning platform is connected to the housing locking module and the lens coupling platform, respectively. The housing locking module and the lens coupling platform are arranged side-by-side on the base and located below the working module. A vacuum suction device is also provided on the lens coupling platform.

[0006] Furthermore, in the above technical solution, the dispensing mechanism includes a dispensing device, a camera device, and a height measuring instrument arranged side by side on the second slide rail assembly. The second slide rail assembly includes at least two slide rail groups. A supplementary lighting device is slidably installed below the camera device.

[0007] Furthermore, in the above technical solution, the collimation device includes one of an optical collimator and a laser collimator. A light box is fixedly installed on the hollow frame. The light box is located above the coupling worktable. A UV lamp for UV curing is also installed on one side of the operating frame. The UV lamp is located below the light box.

[0008] Furthermore, in the above technical solution, the first slide rail assembly includes a horizontal axis slide rail assembly and a vertical axis slide rail assembly. The two ends of the bottom side of the horizontal axis slide rail assembly are connected to the balance column. The vertical axis slide rail assembly is slidably installed on the horizontal axis slide rail assembly. One end of the vertical axis slide rail assembly is slidably connected to the operating frame. The horizontal axis slide rail assembly and the vertical axis slide rail assembly are arranged alternately vertically.

[0009] Furthermore, in the above technical solution, the base is provided with a gripper slide rail assembly, and a gripper module is slidably mounted on the gripper slide rail assembly.

[0033] In this embodiment, a dispensing mechanism 33 and a calibration mechanism 34, which are separately mounted on the coupling worktable 2, are used to calibrate and position the coupling process. At the same time, they are controlled separately by different slide rail components.
