Description

Technical Field

[0001] This utility model belongs to the field of laser component technology, specifically relating to a cross laser component that facilitates angle calibration. Background Technology

[0002] Cross laser assemblies are widely used as key positioning tools in fields such as industrial processing, building decoration, and intelligent equipment. Traditional cross laser assemblies are usually composed of two independent "I"-shaped laser heads, which form a cross positioning line by emitting horizontal and vertical laser lines.

[0003] However, in the process of manufacturing the cross laser assembly, in order to ensure that the emission directions of the two sets of laser heads are strictly perpendicular, the laser heads need to be repeatedly rotated and adjusted during installation. The angles need to be calibrated multiple times by manual observation or with the help of auxiliary instruments. This process consumes a lot of time and reduces assembly efficiency. At the same time, manual adjustment inevitably has visual errors and operational deviations, which may cause the perpendicularity of the laser line to deviate from the design standard, affecting the positioning accuracy and reliability of the equipment. In high-precision scenarios, even a small angular deviation may cause significant positioning errors. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a cross laser assembly that facilitates angle calibration. By setting two sets of mutually perpendicular positioning slots on the laser bracket and configuring positioning components that cooperate with the positioning slots on the laser head, the laser emission directions of the two sets of laser heads are mechanically constrained to a perpendicular relationship. This eliminates the need for repeated manual rotation and angle adjustment, solving the problems of low efficiency and large errors in traditional manual calibration and significantly improving assembly efficiency.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A cross laser assembly for easy angle calibration includes a laser head and a laser bracket for mounting the laser head. The laser head is provided in two sets. The laser bracket is provided with positioning slots for mounting the laser head. The two sets of positioning slots are arranged side by side and the mounting directions of the two sets of positioning slots are perpendicular to each other. The laser head is provided with a positioning element that cooperates with the positioning slots. The laser emission directions of the two sets of laser heads are perpendicular to each other by means of the positioning slots.

[0007] The laser support includes a frame and a mounting sleeve located on the frame and engaging with the laser head. Two sets of mounting sleeves are arranged parallel to each other in the horizontal direction. D-shaped baffles are symmetrically arranged on both sides of the inner wall of the end of the mounting sleeve. The plane of the baffle faces the axis of the mounting sleeve. A positioning groove is formed between the two sets of baffles. The plane of the baffle of one set of mounting sleeves is arranged along the X-axis direction, and the plane of the baffle of the other set of mounting sleeves is arranged along the Y-axis direction.

[0008] The positioning component includes symmetrically arranged limiting plates on both sides of the end of the laser head. The distance between the outer sides of the limiting plates is equal to the width of the positioning groove. The outer side of the limiting plate is a plane and cooperates with the plane of the baffle. The laser head forms a snap-fit ​​engagement with the positioning groove of the laser bracket by means of the limiting plates.

[0009] The laser assembly also includes a square lens, and the gap between the two sets of limiting plates forms a limiting groove. The width of the limiting groove is equal to the width of the lens, and the lens and the limiting groove are interlocked.

[0010] The side of the lens away from the laser head is provided with ripples, and the length direction of the ripples is parallel to the length direction of the limiting plate.

[0011] The beneficial effects of this utility model are:

[0012] This invention establishes two sets of mutually perpendicular positioning slots on the laser bracket and equips the laser head with positioning components that mate with these slots. This mechanical structure forces the laser emission directions of the two laser heads to be perpendicular. Eliminating the need for repeated manual rotation and angle adjustments, precise positioning is achieved directly through the interaction of the positioning components and slots. This solves the problems of low efficiency and large errors associated with traditional manual calibration, significantly improving assembly efficiency and ensuring the consistency and reliability of laser perpendicularity in mass production.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] Specific embodiments, such as Figure 1-7 As shown, a cross laser assembly for easy angle calibration is disclosed. The laser assembly includes a laser head 1 and a laser bracket 2 for mounting the laser head 1. Two sets of laser heads 1 are provided. The laser bracket 2 is provided with positioning grooves 3 for mounting the laser heads 1. The two sets of positioning grooves 3 are arranged side by side and the mounting directions of the two sets of positioning grooves 3 are perpendicular to each other. The laser head 1 is provided with positioning elements that cooperate with the positioning grooves 3. The laser emission directions of the two sets of laser heads 1 are perpendicular to each other by means of the positioning grooves 3.

[0023] In the process of manufacturing the cross laser, in order to ensure that the emission directions of the two sets of laser heads 1 are strictly perpendicular, the laser heads 1 need to be repeatedly rotated and adjusted during installation. The angle is calibrated multiple times by manual observation or with the help of auxiliary instruments. This process consumes a lot of time and reduces assembly efficiency. At the same time, manual adjustment inevitably has visual errors and operational deviations, which may cause the perpendicularity of the laser line to deviate from the design standard, affecting the positioning accuracy and reliability of the equipment. In high-precision scenarios, even a small angular deviation may cause significant positioning errors.

[0024] Therefore, this utility model sets two sets of positioning grooves 3 with mutually perpendicular installation directions on the laser bracket 2, and configures positioning components that cooperate with the positioning grooves 3 on the laser head 1, so that the laser emission directions of the two sets of laser heads 1 are mechanically forced to be perpendicular. Figure 7 As shown. No manual rotation and angle adjustment are required; precise positioning is achieved directly through the cooperation of the positioning component and positioning slot 3. This solves the problems of low efficiency and large errors in traditional manual calibration, significantly improving assembly efficiency and ensuring the consistency and reliability of laser verticality in mass production.

[0025] like Figure 5-7 As shown, the laser support 2 includes a frame 4 and a mounting sleeve 5 located on the frame 4 and fitted with the laser head 1. Two sets of mounting sleeves 5 are arranged parallel to each other in the horizontal direction. D-shaped baffles 6 are symmetrically arranged on both sides of the inner wall of the end of the mounting sleeve 5. The plane of the baffles 6 faces the axis of the mounting sleeve 5. A positioning groove 3 is formed between the two sets of baffles 6. The plane of the baffles 6 of one set of mounting sleeves 5 is arranged along the X-axis direction, and the plane of the baffles 6 of the other set of mounting sleeves 5 is arranged along the Y-axis direction.

[0026] The directions of the X-axis and Y-axis are as follows: Figure 5 As stated in the text, the X-axis is perpendicular to the Y-axis.

[0027] During installation, the laser head 1 is inserted into the installation sleeve 5, and the plane of the limiting plate 7 and the baffle 6 are in contact, automatically limiting the laser emission direction to the strictly vertical X / Y axis direction. This avoids the circumferential rotation of the laser head 1 that may occur in the traditional sleeve structure, simplifies the installation process, and eliminates the angle calibration process by using mechanical positioning, thereby improving assembly efficiency.

[0028] like Figure 2 and Figure 7 As shown, the positioning component includes limiting plates 7 symmetrically arranged on both sides of the end of the laser head 1. The distance between the outer sides of the limiting plates 7 is equal to the width of the positioning groove 3. The outer side of the limiting plate 7 is a plane and cooperates with the plane of the baffle 6. The laser head 1 forms a snap-fit ​​cooperation with the positioning groove 3 of the laser bracket 2 by means of the limiting plate 7.

[0029] The positioning component uses a limiting plate 7 that matches the width of the positioning groove 3. The planes of the limiting plates 7 on both sides engage with the plane of the baffle 6 to form a rigid connection with circumferential positioning. This structure ensures that the laser head 1 cannot rotate around its axis within the mounting sleeve 5, and its laser emission direction is strictly limited by the direction of the limiting plate 7. This achieves a precise installation effect of plug-and-play positioning, reducing reliance on the operator's skills and minimizing the risk of angular deviation caused by external forces such as vibration.

[0030] like Figure 2-4 As shown, the laser assembly also includes a square lens 8, and the gap between the two sets of limiting plates 7 forms a limiting groove. The width of the limiting groove is equal to the width of the lens 8, and the lens 8 and the limiting groove are inserted into each other.

[0031] A limiting groove is formed by the gap between the limiting plates 7, and it is inserted into the square lens 8 to directly link the installation accuracy of the lens 8 with the positioning accuracy of the laser head 1. The width of the lens 8 is the same as the width of the limiting groove, ensuring that its optical axis is strictly aligned with the emission direction of the laser head 1 when the lens 8 is inserted. This avoids the angular deviation caused by manual alignment in traditional lens 8 installation, and ensures that the collimation and perpendicularity of the horizontal / vertical laser lines are not affected by the installation error of the lens 8.

[0032] like Figure 4 As shown, the side of the lens 8 away from the laser head 1 is provided with ripples, and the length direction of the ripples is parallel to the length direction of the limiting plate 7.

[0033] The ripples on lens 8 are used to diffuse the laser beam into a uniform straight spot. Therefore, it is necessary to ensure that the length direction of the ripples is consistent with the direction of the horizontal / vertical laser line to avoid laser line distortion or uneven brightness caused by ripple direction deviation, thereby further improving the positioning accuracy and display effect of the cross laser.
