Description

Technical Field

[0001] The invention relates to the technical field of prefabricated shield segment production, and in particular to a laser transmitter and a detection system. Background Art

[0002] During the construction process, the accuracy of shield segment prefabrication is crucial. To meet this requirement, laser positioning systems have gradually become the mainstream choice due to their high accuracy and repeatability. In the early days, laser positioning systems mainly relied on manual operation, and workers used laser rangefinders and 3D scanners to perform on-site calibration to ensure the correct position and angle of the shield segments. However, with the continuous advancement of automation technology, laser calibration technology has gradually shifted to more complex automatic calibration systems. Modern laser positioning systems are combined with robotic arms to achieve a higher level of precision control, which has promoted the improvement of the level of automation in the shield segment prefabrication process.

[0003] At present, the laser positioning system is usually calibrated by combining laser rangefinder, 3D scanner and laser projection system during the prefabrication process of shield segments. The laser rangefinder is responsible for measuring the actual position of the shield segment, the 3D scanner is used to obtain the 3D model of the shield segment, and the laser projection system assists in construction guidance. In terms of fine-tuning the grating lens, the existing technology still relies on the movement of the robotic arm to adjust the angle of the grating lens.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] At present, the laser positioning system is usually calibrated by combining laser rangefinder, 3D scanner and laser projection system during the prefabrication process of shield segments. The laser rangefinder is responsible for measuring the actual position of the shield segment, the 3D scanner is used to obtain the 3D model of the shield segment, and the laser projection system assists in construction guidance. In terms of fine-tuning the grating lens, the existing technology still relies on the movement of the robotic arm to adjust the angle of the grating lens.

[0035] However, although the movement of the robotic arm can provide a certain degree of angle adjustment range for the grating lens, its flexibility and accuracy are insufficient, making it difficult to provide a control basis for fine-tuning the position and angle of the grating lens. As a result, there is a significant gap between the application of the laser positioning system in the prefabrication process of shield segments and the expected goals, affecting the molding quality of the prefabricated shield segments.

[0036] In order to solve this technical problem, the present invention proposes a laser emitter and a detection system.

[0037] See also Figures 1 to 5In one embodiment of the present invention, the laser transmitter comprises a limit ring 500, a mounting ring 100 and a plurality of hook mechanisms 800. The mounting ring 100 is coaxially arranged with the limit ring 500. An accommodating space 501 is formed between the outer wall of the mounting ring 100 and the inner wall of the limit ring 500. The mounting ring 100 is detachably framed outside the grating lens 700. The plurality of hook mechanisms 800 are spaced apart along the circumference of the limit ring 500. Each hook mechanism 800 is arranged along the axis of the limit ring 500. The two ends of each hook mechanism 800 along the extension direction are respectively a connecting part and a hook part, the connecting part of each hook mechanism 800 is slidably connected to the limiting ring 500 along the axial direction of the limiting ring 500, the hook part of each hook mechanism 800 extends into the accommodating space 501 and is detachably connected to the mounting ring 100, and each hook mechanism 800 is used to drive a part of the mounting ring 100 to tilt toward the limiting ring 500, so as to drive a part of the grating lens 700 to tilt toward the limiting ring 500.

[0038] Specifically, the mounting ring 100 is detachably framed outside the grating lens 700 , which simplifies the maintenance and replacement process of the grating lens 700 and makes the installation and removal of the grating lens 700 more convenient.

[0039] During implementation, multiple hook mechanisms 800 are arranged at intervals along the circumference of the limiting ring 500, and the connecting portion of each hook mechanism 800 can slide along the axial direction of the limiting ring 500, so that the hook mechanism 800 can maintain flexibility during the position and angle adjustment of the grating lens 700. The hook portion extends into the accommodating space 501 and is detachably connected to the mounting ring 100 to ensure that force can be effectively transmitted during the fine-tuning process and to prevent interference between the hook portions, that is, to avoid friction and loss between the other hook portions and the mounting ring 100 when any hook portion drives the mounting ring 100 to tilt, that is, each hook portion is hinged to the mounting ring 100.

[0040] More specifically, the hook mechanism 800 can drive part of the mounting ring 100 to tilt toward the limit ring 500, thereby driving the corresponding part of the grating lens 700 to tilt toward the limit ring 500. The fine-tuning accuracy of the grating lens 700 is improved, so that the laser transmitter can more accurately align the target prefabricated shield segment when performing the laser positioning task, thereby improving the overall performance of the laser positioning system. The reaction speed and accuracy of the laser transmitter can also be flexibly adjusted by setting the number and interval of the hook mechanism 800, and can be adjusted according to the needs of different application scenarios to meet the actual prefabrication requirements of various shield segments. In addition, the hook mechanism 800 can be slidably connected to the limit ring 500, which also effectively reduces the error caused by improper installation and ensures the stability and accuracy of the grating lens 700.

[0041] In addition, by coaxially arranging the mounting ring 100 and the limiting ring 500 , the formed accommodation space 501 can provide space for making way for the mounting ring 100 and the grating lens 700 during the tilting process.

[0042] For ease of understanding, a specific implementation is shown here:

[0043] First, place the grating lens 700 in the mounting ring 100 and ensure that it is correctly aligned with the limit ring 500, and fix the grating lens 700 through the locking mechanism of the mounting ring 100 (such as screws or clamps) to prevent displacement during subsequent adjustments. Ensure that the connecting parts of all hook mechanisms 800 are aligned with the edges of the limit ring 500 and are in a state where no force is applied. Check whether the hook parts of each hook mechanism 800 can smoothly touch the mounting ring 100 to avoid uneven adjustment due to over-tightening or over-loosening. Then, by controlling the operating device of the hook mechanism 800 (such as an electric motor or a manual rotating handle), force is applied to each hook part one by one or simultaneously. The applied force causes the hook part to tilt inward, thereby driving the part of the mounting ring 100 corresponding to this hook mechanism 800 to tilt toward the limit ring 500. At this time, the corresponding part of the grating lens 700 also adjusts its angle accordingly. Next, use a laser rangefinder or other precision measuring tool to monitor the emission angle of the laser beam and provide real-time feedback on the adjustment of the grating lens 700. According to the feedback information, the applied force of the hook mechanism 800 is finely adjusted to make the grating lens 700 reach the desired optimized angle. For some applications, a fixing device (such as an additional locking screw or a clamp) can also be provided to further stabilize the grating lens 700.

[0044] When applying force, attention should be paid to evenly distribute the force to avoid uneven tilt angles of the grating lens 700 due to excessive force of a certain hook mechanism 800. During the adjustment process, the sliding state of each hook mechanism 800 should be checked regularly to ensure that it can remain flexible throughout the process to prevent jamming.

[0045] In the technical solution provided by the present invention, through the synergistic effect of the limit ring 500, the mounting ring 100 and the multiple hook mechanisms 800, the problem that the existing laser positioning system is difficult to provide a control basis for fine-tuning the position and angle of the grating lens 700 during the prefabrication of the shield segment, and it is difficult to fine-tune the grating lens 700. The mounting ring 100 simplifies the maintenance and replacement process of the grating lens 700, making the installation and removal of the grating lens 700 more convenient. Multiple hook mechanisms 800 are arranged at intervals along the circumference of the limit ring 500, and the connecting parts can slide along the axial direction of the limit ring 500, ensuring that each hook mechanism 800 can flexibly adjust the position and angle of the grating lens 700 during the fine-tuning process, ensuring the efficiency and accuracy of the grating lens 700 during the fine-tuning process. In addition, the hook mechanism 800 can drive part of the mounting ring 100 to tilt toward the limit ring 500, thereby driving the corresponding part of the grating lens 700 to tilt, significantly improving the fine-tuning accuracy of the grating lens 700, so that the laser transmitter can more accurately align with the target prefabricated shield segment when performing laser positioning tasks, thereby improving the overall performance of the laser positioning system and improving the molding quality of the prefabricated shield segment.

[0046] Please continue to refer to Figure 2 and Figure 4 As an optional implementation of this embodiment, the laser emitter further includes a limit plate 200 and a clamping mechanism 300, the limit plate 200 is arranged on the mounting ring 100; the clamping mechanism 300 is slidably arranged on the mounting ring 100 along the radial direction of the mounting ring 100, the clamping mechanism 300 and the limit plate 200 are arranged opposite to each other, and the clamping mechanism 300 and the limit plate 200 jointly form a clamping space 301; the grating lens 700 is arranged in the clamping space 301, and the clamping mechanism 300 can move along the radial direction of the mounting ring 100 between a release position away from the grating lens 700 and a clamping position close to the grating lens 700, and correspondingly releases or clamps the grating lens 700.

[0047] It should be noted that the power source for adjusting the clamping mechanism 300 between the release position away from the grating lens 700 and the clamping position close to the grating lens 700 is manual adjustment or a driving motor in the prior art.

[0048] During implementation, when the grating lens 700 is installed in the clamping space 301, the edge of the grating lens 700 is located on the limiting piece 200 and is abutted by the mounting ring 100 to limit the axial displacement of the grating lens 700 on the mounting ring 100; the combined action of the clamping mechanism 300 and the limiting portion 210 limits the radial displacement of the grating lens 700 on the mounting ring 100, and therefore, the position of the grating lens 700 placed in the clamping space 301 is fixed by the limiting piece 200, the mounting ring 100 and the clamping mechanism 300.

[0049] Specifically, the clamping mechanism 300 can move radially along the mounting ring 100, and can be adjusted between a release position away from the grating lens 700 and a clamping position close to the grating lens 700, so as to quickly install and disassemble the grating lens 700, ensuring that it is firmly clamped during operation and easy to release during maintenance or replacement.

[0050] It should be understood that the setting of the mounting ring 100 provides a stable base for the grating lens 700, and the limiting piece 200 thereon can provide a stable mounting point, thereby enhancing the stability and accuracy of the grating lens 700. The limiting piece 200 enables the grating lens 700 to be reliably positioned in the clamping space 301, avoiding the light deviation caused by vibration or other external forces when the laser positioning system is working, thereby improving the overall correction effect. In addition, the clamping mechanism 300 is slidably arranged on the mounting ring 100 along the radial direction of the mounting ring 100, which not only enables the clamping mechanism 300 to be flexibly moved to the clamping position and the release position, but also facilitates the operator to make quick adjustments. In actual operation, the clamping mechanism 300 can effectively control the clamping force of the grating lens 700, ensuring that the grating lens 700 will not be damaged due to excessive pressure during the clamping process. At the same time, the clamping mechanism 300 and the limiting piece 200 are arranged relative to each other to form the clamping space 301 together, further ensuring the stability of the grating lens 700. In addition, the grating lens 700 is arranged in the clamping space 301, and can be released or clamped under the control of the clamping mechanism 300, which greatly simplifies the installation and replacement process of the grating lens 700 and eliminates the inconvenience and risks brought by the traditional threaded connection method. The operator can complete the release and installation of the grating lens 700 in a shorter time, reducing the loss caused by frequent adjustments, thereby effectively improving work efficiency.

[0051] In the technical solution provided by the present invention, the use convenience and reliability of the grating lens 700 are significantly improved through the coordinated setting of the mounting ring 100, the limit plate 200 and the clamping mechanism 300, which not only improves the stability of the grating lens 700, but also enhances its accuracy during calibration operations, effectively preventing the laser positioning system from causing light deviation due to vibration or external force interference during operation, thereby improving the correction effect of the laser light of the laser positioning system. At the same time, the clamping mechanism 300 can slide along the radial direction of the mounting ring 100, so that the grating lens 700 can achieve a simple release or clamping process under the control of the clamping mechanism 300, simplifying the installation and replacement process of the grating lens 700, and eliminating the complexity and potential risks brought by the traditional threaded connection method. In addition, the operator can complete the installation and release of the grating lens 700 in a shorter time, reduce the wear of components caused by frequent adjustments, effectively improve work efficiency, make the use experience of the laser positioning system smoother, and better meet the high-precision and high-efficiency requirements of prefabricated shield segments in modern construction.

[0052] Please continue to refer to Figure 2 and Figure 4 In one embodiment of the clamping mechanism 300, the clamping mechanism 300 includes a guide column 310 and a clamping sheet 330. The clamping sheet 330 and the limiting sheet 200 together form a clamping space 301. The guide column 310 extends along the radial direction of the mounting ring 100. The guide column 310 is installed on the outer wall of the mounting ring 100. The clamping sheet 330 is slidably installed on the guide column 310 and can move between a release position and a clamping position to release or clamp the grating lens 700 accordingly.

[0053] Specifically, the clamping piece 330 and the limiting portion 210 of the limiting piece 200 together form a clamping space 301 for accommodating the grating lens 700. The clamping piece 330 can move between a release position and a clamping position to achieve the release or clamping of the grating lens 700. The guide post 310 extends along the radial direction of the mounting ring 100 and is mounted on the outer wall of the mounting ring 100. The clamping piece 330 can be slidably mounted on the guide post 310 to guide the movement of the clamping piece 330 in the radial direction of the mounting ring 100, thereby improving the clamping stability of the grating lens 700. The elastic reset member 320 is sleeved on the guide post 310 and is located between the clamping piece 330 and the mounting ring 100. To provide elastic force, the clamping piece 330 automatically returns to the preset position after release, ensuring that the clamping piece 330 can stably clamp the grating lens 700.

[0054] In another embodiment of the clamping mechanism 300, the clamping mechanism 300 further includes a radial displacement driving member, which is mounted on the mounting ring 100. The radial displacement driving member is connected to the clamping plate 330 and is used to drive the clamping plate 330 to move between a release position and a clamping position, thereby releasing or clamping the grating lens 700 accordingly.

[0055] Specifically, the radial displacement drive provides power support for the clamping mechanism 300, so that the operator can quickly adjust the position of the clamping piece 330 through simple operations, and can easily complete the clamping or release of the grating lens 700, greatly reducing the complexity and time cost of manual operation. In addition, the radial displacement drive also ensures the stability of the clamping piece 330 during the movement process, avoiding damage to the grating lens 700 due to unnecessary shaking during clamping or release. In addition, the use of the radial displacement drive also effectively improves the accuracy of the operation, so that the grating lens 700 can be accurately positioned in the clamping space 301, further enhancing the overall performance of the laser positioning system.

[0056] Please continue reading Figure 2 and Figure 4 In another embodiment of the clamping mechanism 300, the clamping mechanism 300 also includes an elastic return member 320, which is sleeved on the guide column 310, and one end of the elastic return member 320 is connected to the clamping plate 330, and the other end of the elastic return member 320 is connected to the mounting ring 100.

[0057] Specifically, the provision of the elastic reset member 320 greatly enhances the automation function of the clamping mechanism 300. When the operator moves the clamping plate 330 to the release position, the elastic reset member 320 will restore the clamping plate 330 to the clamping position through its elastic properties. This automatic reset function not only reduces the operator's manual intervention and improves work efficiency, but also ensures that the grating lens 700 will not fall off due to accidental collision in the non-clamped state. In addition, the elastic reset member 320 can absorb external shocks or vibrations, further enhancing the stability of the clamping plate 330, so as to effectively avoid the position displacement of the grating lens 700 caused by vibration, and ensure the accuracy and stability of the laser light.

[0058] More specifically, the elastic reset member 320 is a spring, one end of the elastic reset member 320 is connected to the side of the clamping piece 330 facing the mounting ring 100, and the other end of the elastic reset member 320 is connected to the outer wall of the mounting ring 100. In this embodiment, the guide column 310 is used to provide a stable sliding path for the clamping piece 330, and combined with the deformation reset function of the elastic reset member 320, it is ensured that the clamping piece 330 can be quickly and reliably moved to the desired position, thereby enhancing the convenience and stability of the assembly and disassembly operation of the grating lens 700.

[0059] In another embodiment of the clamping mechanism 300 , a buffer 400 is disposed on both the clamping piece 330 and the side of the limiting portion 210 of the limiting piece 200 facing the grating lens 700 .

[0060] It should be noted that the buffer member 400 is a rubber member in the prior art.

[0061] Specifically, the buffer 400 can effectively absorb the impact force between the clamping piece 330 and the grating lens 700, reduce the damage caused by collision during the clamping or releasing process, and thus protect the grating lens 700 and its optical properties. In addition, during the operation of the laser transmitter, vibration or external impact may occur, and the buffer 400 can provide additional shock absorption effect to ensure that the grating lens 700 always maintains a stable working state. In addition, by using the buffer 400 to provide a soft contact surface during the clamping process, it helps to prevent the grating lens 700 from being offset or inaccurately positioned during the clamping process, thereby improving the overall calibration accuracy of the laser positioning system. In addition, the use of the buffer 400 can reduce the wear and tear on the clamping mechanism 300 and the grating lens 700 caused by frequent operations, thereby extending the service life.

[0062] In an embodiment of the limiting piece 200 , there are multiple limiting pieces 200 , and the multiple limiting pieces 200 are arranged at intervals along the circumference of the mounting ring 100 , and the clamping mechanism 300 is arranged opposite to any limiting piece 200 .

[0063] Specifically, the plurality of stoppers 200 are distributed along the circumference of the mounting ring 100, which can provide more uniform support for the grating lens 700 when clamping it, ensuring that the grating lens 700 can be stably fixed during the clamping process, reducing local stress concentration. In addition, the provision of the plurality of stoppers 200 makes the adjustment of the clamping space 301 more flexible, and can adapt to grating lenses 700 of different types or sizes, thereby enhancing the compatibility of the laser transmitter.

[0064] It should be noted that the relative setting in this embodiment refers to the relative positional relationship, including but not limited to a symmetrical relationship. The relative setting may also refer to the setting of the clamping piece 330 relative to the gap between two adjacent limiting pieces 200.

[0065] Please continue reading Figures 1 to 4 , and see Figure 5 and Figure 7In an embodiment of the present invention, each hook mechanism 800 includes a hook assembly 810, a hinge seat 820, a guide bar 830 and an axial displacement driving member 840. The hook assembly 810 forms a hook portion, and the guide bar 830 forms a connecting portion; one end of the hook assembly 810 is hinged to the guide bar 830 through the hinge seat 820, and the other end of the hook assembly 810 is detachably connected to the mounting ring 100. The axial displacement driving member 840 is installed on the limiting ring 500. The axial displacement driving member 840 is connected to the guide bar 830 and is used to drive the guide bar 830 to slide along the axial direction of the limiting ring 500, so as to drive a portion of the mounting ring 100 to tilt toward the limiting ring 500, and to make a portion of the grating lens 700 tilt toward the limiting ring 500.

[0066] Specifically, at the beginning of the implementation process, the axial displacement driving member 840 receives a control signal, and after being activated, the axial displacement driving member 840 drives the guide bar 830 to slide along the axial direction of the limiting ring 500. One end of the hook assembly 810 is hinged to the guide bar 830, and the other end is detachably connected to the mounting ring 100. As the guide bar 830 moves, the hook assembly 810 tilts through the hinge seat 820, so that the hook assembly 810 can be flexibly rotated during adjustment, thereby effectively adjusting the angle of the mounting ring 100. When the guide bar 830 slides along the limiting ring 500, the hook part is connected to the mounting ring 100, causing part of the mounting ring 100 to tilt toward the limiting ring 500, thereby causing the corresponding part of the grating lens 700 to tilt toward the limiting ring 500.

[0067] More specifically, the axial displacement driving member 840 can be used to drive the guide bar 830 to perform reciprocating linear motion along the circumference of the mounting ring 100 and the limiting ring 500 , so that the mounting ring 100 drives the grating lens 700 to tilt or reset.

[0068] This embodiment significantly improves the fine-tuning accuracy of the grating lens 700, so that the laser transmitter can more accurately align the target prefabricated shield segment when performing the laser positioning task. In addition, the hook mechanism 800 not only enhances the stability during the fine-tuning process, but also ensures the flexibility and accuracy of the adjustment process of the grating lens 700, thereby effectively improving the overall performance of the laser positioning system.

[0069] Please continue reading Figure 5 In an embodiment of the present invention, the hook assembly 810 includes a mounting plate 811 and a hook member 812. The mounting plate 811 is spaced apart from the inner wall of the mounting ring 100. The hook member 812 is L-shaped. One end of the hook member 812 is connected to the mounting plate 811. The other end of the hook member 812 is spaced apart from the mounting plate 811 to form a hook space 801. Part of the mounting ring 100 is disposed in the hook space 801.

[0070] Specifically, the hook space 801 not only ensures the stability of the mounting ring 100 during the adjustment process, but also provides the necessary flexibility for fine-tuning the grating lens 700. When adjusting, part of the grating lens 700 can be tilted in the hook space 801 at the non-powered end, thereby avoiding friction and loss between part of the grating lens 700 and the hook assembly 810.

[0071] Please continue reading Figure 5 In an embodiment of the present invention, the articulated seat 820 includes a first rotating shaft 821, a second rotating shaft 822 and a connecting strip 823. The first rotating shaft 821 and the second rotating shaft 822 are arranged at radial intervals along the limiting ring 500. The first rotating shaft 821 is installed on the guide strip 830, and the second rotating shaft 822 is installed on the hook member 812. The first rotating shaft 821 is rotatably connected to one end of the connecting strip 823, and the second rotating shaft 822 is rotatably connected to the other end of the connecting strip 823.

[0072] Specifically, the first rotating shaft 821 is mounted on the guide bar 830, and the second rotating shaft 822 is mounted on the hook member 812. The first rotating shaft 821 is rotatably connected to one end of the connecting bar 823, and the second rotating shaft 822 is also rotatably connected to the other end of the connecting bar 823, so that the hook member 812 can rotate freely during the adjustment process, thereby improving the flexibility and accuracy of the hook mechanism 800. Through the hinge seat 820, the hook assembly 810 can effectively cooperate with the guide bar 830 to achieve fine adjustment of the grating lens 700. It ensures that the grating lens 700 can be accurately adjusted in angle when the laser transmitter is in operation, thereby improving the performance and reliability of the laser positioning system.

[0073] Please continue reading Figure 1 , Figure 2 , Figure 3 and Figure 7 In an embodiment of the present invention, a through groove 502 is formed on the limiting ring 500 , and the through groove 502 extends along the axial direction of the limiting ring 500 . The guide bar 830 extends into the through groove 502 and is slidably connected to the limiting ring 500 .

[0074] Specifically, a through groove 502 is formed on the limiting ring 500, and the through groove 502 extends along the axial direction of the limiting ring 500, and the guide bar 830 can slide therein. The through groove 502 structure of the limiting ring 500 provides a stable guide for the guide bar 830, thereby improving the accuracy of the grating lens 700 during the adjustment process.

[0075] In an embodiment of the present invention, the laser emitter also includes a plurality of vibration damping mechanisms 600, and the plurality of vibration damping mechanisms 600 are alternately arranged with the plurality of hook mechanisms 800; the plurality of vibration damping mechanisms 600 are arranged at intervals along the circumference of the limiting ring 500, and each vibration damping mechanism 600 extends along the axial direction of the limiting ring 500; the two ends of each vibration damping mechanism 600 along its extension direction are respectively a free end and a connecting end, the connecting end of each vibration damping mechanism 600 is connected to the limiting ring 500, and the free end of each vibration damping mechanism 600 extends into the accommodating space 501 and is connected to the mounting ring 100.

[0076] Specifically, a plurality of vibration reduction mechanisms 600 are arranged at intervals along the circumference of the limiting ring 500, so that the vibration reduction mechanisms 600 are evenly distributed within the entire circumference of the limiting ring 500, thereby reducing the impact of vibration on the grating lens 700 when the robot moves. The connection end of the vibration reduction mechanism 600 is connected to the limiting ring 500, ensuring its stability and reliability, so that the free end can effectively absorb and dissipate the vibration from the robot. Such an arrangement not only enhances the stability of the grating lens 700, but also significantly extends the service life of the grating lens 700, reducing wear and tear and maintenance frequency.

[0077] More specifically, the free end of each vibration reduction mechanism 600 extends into the accommodating space 501 and is connected to the mounting ring 100. The vibration reduction mechanism 600 can effectively isolate the external vibration transmission during operation to prevent the vibration from directly acting on the grating lens 700. In addition, the vibration reduction mechanism 600 can be adjusted according to the specific use environment to adapt to different vibration frequencies and amplitudes, thereby providing a guarantee for the precise positioning of the grating lens 700. Multiple vibration reduction mechanisms 600 not only improve the stability and durability of the grating lens 700, but also significantly reduce the maintenance and replacement frequency of the grating lens 700. The vibration reduction mechanism 600 can effectively absorb and dissipate the vibration from the robot arm, reduce the direct impact of the vibration on the grating lens 700, and enable the grating lens 700 to maintain a good working condition in long-term practical applications, thereby extending its service life.

[0078] Please continue reading Figures 1 to 4 , and see Figure 6 In an embodiment of the present invention, the vibration reduction mechanism 600 includes a connecting seat 610, a compression spring 620 and a clamping jaw assembly 630. The connecting seat 610, the compression spring 620 and the clamping jaw assembly 630 are arranged at intervals along the circumference of the limiting ring 500. The connecting seat 610 is connected to the inner wall of the limiting ring 500 to form a connecting end. One end of the compression spring 620 is connected to the connecting seat 610, and the other end of the compression spring 620 is connected to the clamping jaw assembly 630. The clamping jaw assembly 630 is detachably clamped to the outer wall of the mounting ring 100 to form a free end.

[0079] Specifically, the connection seat 610 is connected to the inner wall of the limiting ring 500 to form the connection end of the vibration reduction mechanism 600, thereby ensuring the reliability and stability of the vibration reduction mechanism 600 during operation. One end of the compression spring 620 is connected to the connection seat 610, and the other end is connected to the clamping jaw assembly 630. The function of the compression spring 620 is to provide a moderate elastic force so that the clamping jaw assembly 630 can maintain flexibility and recovery ability when subjected to external vibration, thereby effectively absorbing and buffering vibration.

[0080] More specifically, the clamping jaw assembly 630 is detachably clamped to the outer wall of the mounting ring 100, which improves the convenience of maintenance. When the staff is maintaining or replacing the grating lens 700, the clamping jaw can be quickly released for easy operation without disassembling the entire structure. At the same time, the clamping jaw assembly 630 can firmly clamp the grating lens 700, ensuring that it is not disturbed unnecessarily in the working state, further reducing the risk of wear.

[0081] As an optional implementation of this embodiment, the compression spring 620 in the vibration reduction mechanism 600 not only provides a structural basis for the reset of the mounting ring 100 after tilting, but also ensures that the side of the mounting ring 100 facing the limit ring 500 is always kept in a tensioned state. This design enhances the stability of the mounting ring 100 when tilting, thereby improving the tilt control accuracy of the grating lens 700.

[0082] In specific implementation, when a certain hook mechanism 800 hooks one side of the mounting ring 100, the mounting ring 100 will be affected and tilted. Meanwhile, the other unaffected hook mechanisms 800 remain stationary. During the tilting process of the mounting ring 100, the compression spring 620 of the vibration reduction mechanism 600 will apply tension to ensure the stability of the mounting ring 100.

[0083] When the hook mechanism 800 is reset, the compression spring 620 will return to the initial state, so that the mounting ring 100 is also reset along with the hook mechanism 800. The main function of the hook mechanism 800 is to achieve the tilting of the mounting ring 100 without the need for complex connections or adjustments, which can effectively reduce the contact area and assembly points between the hook mechanism 800 and the mounting ring 100, and improve the durability of the hook mechanism 800 and the mounting ring 100. The stability and long-term reliability of the laser positioning system during use are ensured, while simplifying the assembly and maintenance process.

[0084] In an embodiment of the present invention, the clamping jaw assembly 630 includes an arc plate 631 and a limiting bar 632, the limiting bar 632 is L-shaped, one end of the limiting bar 632 is connected to the arc plate 631, and the other end of the limiting bar 632 and the arc plate 631 are spaced to form an assembly space 601, a portion of the mounting ring 100 is arranged in the assembly space 601, and the arc plate 631 has a curvature that is compatible with the mounting ring 100.

[0085] Specifically, the limiting strip 632 is L-shaped, one end of which is connected to the arc plate 631 and the other end is spaced apart from the arc plate 631 to form an assembly space 601, so that the clamping jaw assembly 630 can flexibly adapt to the shape of the mounting ring 100 during the clamping process.

[0086] The assembly space 601 allows part of the mounting ring 100 to be smoothly placed therein, thereby ensuring a good fit between the clamping jaw assembly 630 and the mounting ring 100. The curvature of the arc plate 631 is adapted to the mounting ring 100. This matching design not only enhances the stability of the clamping, but also ensures that the clamping jaw assembly 630 can apply pressure evenly during clamping, thereby reducing potential damage to the grating lens 700. Through the combination of the arc plate 631 and the limit bar 632, the clamping jaw assembly 630 can provide a smooth and reliable operating experience during the clamping and releasing process. Especially when maintaining or replacing the grating lens 700, the user can easily adjust the clamping jaw assembly 630 to achieve quick release or clamping without affecting the overall stability of the laser positioning system.

[0087] In the embodiment of the present invention, a vibration isolation pad is disposed on the side of the limiting strip 632 and the arc plate 631 facing the mounting ring 100 .

[0088] Specifically, the vibration isolation pad can effectively isolate the vibration from the robot arm or other external sources and play a buffering role. The vibration isolation pad is combined with the limit bar 632 and the arc plate 631 to form a multi-level vibration reduction system. The vibration isolation pad can further absorb and dissipate the vibration energy and reduce the possibility of them being transmitted to the mounting ring 100 and the grating lens 700.

[0089] In addition, when the clamping jaw assembly 630 clamps the grating lens 700, the vibration isolation pad can provide more uniform pressure and avoid slight displacement caused by vibration, thereby further protecting the accuracy and stability of the grating lens 700.
