Description

Technical Field

[0001] This utility model relates to the field of laser positioning technology, specifically a laser product positioning fixture. Background Technology

[0002] A laser is a device that emits laser light. Except for free-electron lasers, the basic working principle of all lasers is the same. The essential conditions for generating laser light are population inversion and gain exceeding loss. Therefore, the essential components of a laser device are an excitation (or pump) source and a working medium with metastable energy levels. Excitation occurs when the working medium absorbs external energy and is excited to an excited state, creating the conditions for achieving and maintaining population inversion. Based on the working medium, lasers can be divided into four main categories: gas lasers, solid-state lasers, semiconductor lasers, and dye lasers. Recently, free-electron lasers have also been developed, and high-power lasers are typically pulsed. The pure quality and stable spectrum of the light emitted by lasers allow for applications in many fields. Laser products require positioning fixtures for positioning during use.

[0003] A fiber laser positioning fixture, with application number 202221737606.X, is disclosed in the prior art. It includes a fixing plate, the upper surface of which is used to place the fiber laser. A first side baffle is fixed to one side of the upper surface of the fixing plate, and a second and third side baffles are respectively fixed to the other side. A notch for accommodating a fiber optic connector is provided between the second and third side baffles. A positioning arm is provided on one side of the upper surface of the fixing plate, located on the opposite side of the second and third side baffles. One end of the positioning arm can be tightly pressed against the corner of the fiber laser's side, and the other end is connected to the sliding end of a linear sliding mechanism. This invention achieves fiber laser positioning through the cooperation of multiple side baffles and positioning arms, ensuring that the fiber laser's position remains fixed during the coupling installation of FAC lenses, SAC lenses, and reflectors, thus improving the automation efficiency and accuracy of the coupling installation. However, the stability of the clamping and fixing is relatively poor, disassembly and assembly are inconvenient, and it is not convenient to adjust the laser positioning tilt angle. Utility Model Content

[0004] The purpose of this utility model is to provide a laser product positioning fixture to solve the problems of the existing technology, such as the relatively poor stability of clamping and fixing, inconvenience of disassembly and assembly, and difficulty in adjusting the laser positioning tilt angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser product positioning fixture, comprising a base, a lower support on the upper side of the base, positioning holes at both ends of the base, an upper support inside the lower support via a first lead screw, a positioning upper support plate rotatably mounted on one end of the upper support via a connecting shaft, a fixed clamping plate on one side of the upper end of the positioning upper support plate, a limiting slider in the groove on the upper side of the other end of the positioning upper support plate via a second lead screw, and a movable clamping plate on the upper side of the limiting slider, a laser product clamping groove on one side of both the fixed clamping plate and the movable clamping plate, and a first motor connected to one end of the connecting shaft via a gear set.

[0013] 1. This utility model features a fixed clamping plate on one side of the upper end of the positioning support plate, and a limiting slider and a movable clamping plate in the groove on the upper side of the other end of the positioning support plate via a second lead screw.

[0015] 3. In this utility model, the lower bracket is equipped with an upper bracket through a first lead screw. One end of the upper bracket is rotatably equipped with a positioning upper support plate through a connecting shaft, so that the upper bracket can be driven to rise and fall and adjust through the first lead screw, thereby adjusting the usage height of the positioning upper support plate and thus meeting the positioning and use of laser products of different heights.
