Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically to a laser cross module. Background Technology

[0002] A laser line projector is a precision tool that uses laser technology to project straight lines or planes. It is widely used in fields such as construction, decoration, and industrial measurement. By emitting visible laser beams of red, green, or blue light, it forms clear horizontal, vertical, or intersecting lines on walls, floors, or in space to assist in marking positions, aligning objects, or detecting flatness.

[0003] Laser line projectors use semiconductor lasers as their light source, diffusing the laser point into a uniform straight line or fan-shaped light band through an optical lens group, projecting it onto the target surface to form a high-brightness mark. Equipped with an automatic leveling system such as a gravity sensor or gyroscope, it ensures that the laser line maintains horizontal and vertical accuracy even when placed at different angles. The laser line projector has extremely low straightness error, with some models supporting fine-tuning to ensure precise alignment. It is small and lightweight; the mini model is only palm-sized, making it easy to carry and operate. Its fully sealed design makes it shockproof and drop-resistant, suitable for harsh environments such as construction sites and workshops.

[0004] The core component of a laser line projector is the laser module. However, the components of a common laser module are usually integrated as a whole, making it difficult to replace individual damaged parts when a fault occurs, resulting in high operating costs. Therefore, the laser cross module is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laser cross module, which features modular design of each component of the laser module, making it easy to replace individual components. This solves the problem that in common laser modules, each component is usually a single unit, making it difficult to replace individual damaged components when a fault occurs, resulting in high usage costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A laser cross module includes a mounting base, an adjustment component is fixedly mounted on one side of the mounting base, a cross laser head is fixedly mounted on one side of the adjustment component, and a light-emitting module is internally threaded on the side of the mounting base away from the adjustment component.

[0008] The light-emitting module includes a lens barrel threadedly installed inside the mounting base on the side away from the adjustment component. A heat sink is threadedly installed inside the lens barrel. A light-emitting tube is fixedly installed inside the heat sink. A circuit board is fixedly installed on one side of the light-emitting tube. A wire extending to the outside of the mounting base is fixedly installed on one side of the circuit board. An optical lens, a copper gasket, and a focusing lens are sequentially placed inside the lens barrel near the adjustment component. A lens cap is threadedly installed on the surface of the lens barrel near the adjustment component.

[0009] Furthermore, a through hole is provided on one side of the copper pad, and a through hole is provided on one side of the mirror cap.

[0010] Furthermore, the adjustment assembly includes an adjustment base, on which two pads are fixedly installed on two mutually distant sides. A horizontal adjustment plate is fixedly installed on one side of one of the pads, and a vertical adjustment plate is fixedly installed on one side of the other pad. The horizontal adjustment plate is fixedly installed on one side of the mounting base.

[0011] Furthermore, two vertical adjustment screws are threaded on one side of the cross laser head, and two horizontal adjustment screws are threaded on the other side of the cross laser head.

[0012] Furthermore, the cross laser head includes a mounting housing fixedly installed on one side of the adjustment assembly. A horizontal emission port is opened on one side of the mounting housing, a vertical emission port is opened on another side of the mounting housing, a horizontal cylindrical lens passes through one side of the mounting housing, and a vertical cylindrical lens passes through the top of the mounting housing.

[0013] Furthermore, the horizontal cylindrical lens is aligned with the horizontal emission port, the vertical cylindrical lens is aligned with the vertical emission port, and the horizontal and vertical emission ports are perpendicular to each other.

[0014] Furthermore, one end of the vertical adjustment screw contacts one side of the horizontal adjustment plate, and one end of the horizontal adjustment screw contacts one side of the adjustment base.

[0015] Furthermore, both sides of the mounting housing that are far apart from each other are threaded with angle adjustment screws, one end of which is in contact with one side of the vertical cylindrical lens.

[0016] Compared with the prior art, the present invention provides a laser cross module, which has the following beneficial effects:

[0017] 1. This laser cross module connects to the lens barrel via an internal thread on one side of the mounting base. A heat sink and a light-emitting tube are installed at one end of the lens barrel via an internal thread. An optical lens, copper gasket, and focusing lens are encapsulated inside the other end of the lens barrel via a lens cap that is threaded to the lens barrel. This allows for easy disassembly and replacement of easily damaged components such as the heat sink, light-emitting tube, optical lens, copper gasket, and focusing lens within the light-emitting module of the laser cross module. This solves the problem that in common laser modules, the components are usually integrated, making it difficult to replace individual damaged components when a fault occurs, resulting in high operating costs.

[0018] 2. This laser cross module uses an adjustment component between the mounting base and the cross laser head. A horizontal adjustment plate and a vertical adjustment plate are installed on both sides of the adjustment base using pads. The angle of the cross laser head is adjusted using vertical and horizontal adjustment screws. Attached Figure Description

[0029] Please see Figure 1 and Figure 4 In this embodiment, the adjustment assembly 2 includes an adjustment base 21.
