A laser calibration device

Abstract

The invention discloses a laser calibrating device comprising a cylinder body; the cylinder body is provided with a rotatable adjustment ring; the adjustment ring comprises a first adjustment ring anda second adjustment ring; an interval is arranged between the first adjustment ring and the second adjustment ring; outer rings of the adjustment rings are arranged concentrically with the cylinder body; and inner rings of the adjustment rings are eccentrically disposed with respect to the center of the outer rings; and the inner rings of the first adjustment ring and the second adjustment ring are eccentric to the same degree; the inner rings of the adjustment rings are in contact with the outer circumference of a cylindrical laser member built in the cylinder body; and the laser member rotates in accordance with the rotation of the adjustment rings. When the eccentrically arranged adjustment rings are rotated, a laser component can be driven to rotate in a circular direction. Because there are two adjustment rings in the front and back positions, the laser component can be adjusted to an appropriate angle when the adjustment rings rotate so as to achieve the purpose of calibrating the laser. There is no need for complicated operations, only the adjustment rings need to be rotated to quickly and easily calibrate the laser component.

Description

technical field [0001] The present invention relates to the technical field of calibration, and more specifically, to a laser calibration device. Background technique [0002] In the production of electronic products, generally electronic imaging products with laser pointers need to coincide the laser spot with the cross cursor on the screen of the electronic product, but due to assembly and processing errors, often the laser cannot coincide with the cross cursor after assembly, so a laser The adjustment structure is fine-tuned after assembly. [0003] In order to achieve the purpose of overlapping the laser and the cross cursor, there are two commonly used methods on the market at present. The first is to add a screw stop on the assembly surface of the laser. Fine-tuning, however, the operation of screw stop adjustment is more complicated. In order to ensure the adjustment angle and stability, two stop screws are generally required to be locked at the same time, and the ad...

[0005] However, the method of moving the cross cursor by software so that it coincides with the laser has high requirements for the laser assembly position, and after adjustment, the cross cursor is generally not at the center of the screen
