Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to a laser integrated module and a laser detector. Background Technology

[0002] A laser detector is a security device based on laser technology. It consists of a transmitter and a receiver. The transmitter emits a laser beam towards the receiver, creating an invisible laser warning line between them. When an object blocks the laser beam, the laser signal received by the receiver changes, triggering an alarm mechanism.

[0003] Among these applications, beam parallelization technology is of great significance in laser beam detectors. In numerous application scenarios, beam parallelization is a fundamental requirement. In the laser processing industry, multiple parallel laser beams can improve processing efficiency and accuracy, facilitating the rapid processing of complex patterns; in the field of laser measurement, parallel beams enable precise distance and angle measurements, providing accurate data for multiple industries; and in the field of communications, parallel laser beams are beneficial for achieving high-speed and stable optical communication.

[0004] To achieve parallel beams, the laser tube's packaging must ensure the stability and precision of its internal structure. Even the slightest deviation during packaging can alter the beam's emission angle, thus affecting its parallelism. For example, a slight misalignment in the laser tube's fixed position during packaging can cause the beam to tilt, making it difficult to achieve the required parallelism. Utility Model Content

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the present invention proposes a laser integrated module in the first aspect, which includes a housing 100, a plurality of light source emitters 200 and a plurality of fine-tuning components 300. The housing 100 is provided with a plurality of placement holes 101, and the plurality of light source emitters 200 are respectively placed in the plurality of placement holes 101. The plurality of fine-tuning components 300 are mounted on the housing 100 and respectively extend into the plurality of placement holes 101 and are connected to each surface of the light source emitters 200 to control the placement angle of the light source emitters 200 in the placement holes 101.

[0030] Specifically, multiple light source emitters 200 can be mounted in the housing 100. However, it is important to ensure that at least one visible light laser emitter and at least one invisible light laser emitter are present among these multiple emitters 200. The visible light laser emitter assists the invisible light laser emitter. Crucially, it is essential to ensure that the beams of both types of emitters 200 are parallel, allowing the user to easily determine the emission path of the invisible light laser emitter using the visible light laser emitter. In this embodiment, the housing 100 has a small volume structure and only mounts one visible light laser emitter and one invisible light laser emitter. The laser emitters are arranged side by side. To ensure that the beams of the two emitters are parallel, the number of fine-tuning components 300 corresponds to the number of light source emitters 200, and they extend into the corresponding placement holes 101 to connect with the corresponding visible or invisible laser emitters. By adjusting the fine-tuning components 300, the placement angle of the visible and invisible laser emitters can be adjusted, thereby achieving the goal of fine-tuning the beams emitted by the visible and invisible laser emitters to be parallel to each other. The invisible laser emitter requires a special detection instrument for identifying invisible light to determine the relative position of its emitted invisible light and the beam emitted by the visible laser emitter.

[0031] Furthermore, the placement hole 101 includes a fine-tuning space 1011, in which the light source emitter 200 performs fine-tuning of the placement angle within the fine-tuning space 1011 via the fine-tuning component 300.

[0032] The fine-tuning component 300 includes multiple fasteners 301. The housing 100 is provided with multiple fine-tuning holes 102 that are radially connected to multiple placement holes 101. The fasteners 301 are inserted into the placement holes 101 and connected to the light source emitter 200.

[0033] In this embodiment, in order to ensure that the light source emitter 200 has adjustable space within the placement hole 101, the size of the placement hole 101 is larger than the size of the light source emitter 200. This extra space is the fine-tuning space 1011 of the light source emitter 200, which can be adjusted by the fine-tuning component 300. The fastener 301 and the fine-tuning hole 102 are set in such a way that the fastener 301 enters from the fine-tuning hole 102 and is placed in the placement hole 101 to abut against the light source emitter 200. Through this abutting method, the tightness of each surface of the light source emitter 200 is adjusted to different degrees, thereby determining the placement position of the two light source emitters 200 within the placement hole 101, so that the beams of the two light source emitters 200 approach or become parallel.

[0034] In this embodiment, the fastener 301 includes a precision screw, and the fine-tuning hole 102 includes a threaded hole. The threaded engagement enables more precise fine-tuning operations, thereby improving the accuracy of the beams of the two light source emitters 200 approaching parallelism and reducing errors. It should be noted that the end of the fastener 301 adopts a planar or fitted shape structure design that conforms to the contact surface with the light source emitter 200, thereby increasing the contact area between the fastener 301 and the light source emitter 200. This ensures that when the fastener 301 contacts the light source emitter 200, the fine-tuning effect can be guaranteed without damaging the body of the light source emitter 200.

[0035] Furthermore, a plurality of fine-tuning holes 102 are disposed in two orthogonal radial directions of the placement hole 101.

[0036] Multiple fine-tuning holes 102 located in the same radial direction are arranged in an axial array along the placement hole 101.

[0037] Specifically, the arrangement of multiple fine-tuning holes 102 in two orthogonal radial directions of the placement hole 101 is for fine-tuning the x-axis and y-axis of the light source emitter 200, as shown in the attached figure. Figure 3 As shown, the top of the placement hole 101 is provided with an annular protrusion, which is used to ensure the normal emission of the light beam from the light source emitter 200, and also to position the light source emitter 200 on the z-axis. Therefore, the z-axis does not need to be adjusted. Figure 1 As shown, multiple fine-tuning holes arranged coaxially and in an array are used for fine-tuning the light source emitter 200 in different directions along this axis. For example, two fine-tuning holes 102 with a certain spacing are arranged coaxially. Assuming it is along the x-axis, see the attached diagram again. Figure 3 The upper fine-tuning hole 102, when the fastener 301 is inserted and contacts the light source emitter 200, causes the upper part of the light source emitter 200 to move to the left relative to its lower part. This leftward movement is defined as the positive x-axis direction. Conversely, when the fastener 301 is inserted into the lower fine-tuning hole 102 and contacts the light source emitter 200, the lower part of the light source emitter 200 moves to the right relative to its upper part, specifically in the negative x-axis direction. It is important to note that the positive and negative directions of movement are based on the beam emitted by the light source emitter 200, and the leftward or rightward movement is only within the range specified in the fine-tuning hole 102. Figure 3 To illustrate, the fine-tuning operation on the y-axis is the same as the fine-tuning operation on the x-axis described above, in order to perform more precise fine-tuning control on the two light source emitters 200, so that the beams emitted by the two light source emitters 200 can more accurately approach parallelism.

[0038] Furthermore, the box body 100 is provided with injection holes 103 that are respectively connected to multiple placement holes 101.

[0039] Specifically, after the fine-tuning operation is performed on the two light source emitters 200, in order to maintain the position of the two light source emitters 200 for a long time and not be easily disturbed by external factors, in this embodiment, a gel-like substance such as sealant is injected into the injection hole 103 to fix the two light source emitters 200. After the sealant cures in the placement hole 101, it can wrap the two light source emitters 200 and fix the two light source emitters 200.

[0040] Furthermore, rotating shaft platforms 104 are provided on both sides of the box body 100, and multiple limiting protrusions 105 are provided on both sides of the box body 100.

[0041] In a second aspect, this utility model provides a laser detector, including a laser integrated module as described in any of the above-described solutions.

[0042] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
