Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to a laser collimation and adjustment device. Background Technology

[0002] With the widespread application of laser technology in industrial processing and other fields, the precise detection and adjustment of laser beam quality has become a key aspect of ensuring the performance of laser systems. The core objective of beam collimation adjustment is to obtain a parallel beam with a minimal divergence angle and uniform energy distribution, a process that relies on the precise measurement and analysis of the far-field spot morphology and size.

[0003] In related technologies, white screens and apertures are commonly used as receiving fixtures, and collimation is performed by observing the uniformity, roundness, and divergence of the laser spot as a function of distance. However, when the laser power density is high, the beam energy is easily focused on the surface of the fixture, which can quickly lead to thermal damage or even burnout of the receiving fixture. Summary of the Invention

[0004] The main objective of this invention is to provide a laser collimation and adjustment device, which aims to achieve collimation and adjustment of high-power lasers.

[0005] To achieve the above objectives, the present invention provides a laser collimation and adjustment device, the laser collimation and adjustment device comprising: Mounting plate; A fixing component, disposed on the mounting plate, is used to fix the laser; A power adjustment component is disposed on the mounting plate and located on the light output path of the laser, and is used to adjust the light intensity of the laser emitted by the laser. A camera, mounted on the mounting plate, is used to capture the light spot of the laser emitted by the power adjustment component; and A display, which is electrically connected to the camera, displays the light spots captured by the camera.

[0006] In one embodiment, the power adjustment component includes a first attenuator and a second attenuator, the second attenuator being disposed on the side of the first attenuator away from the fixing component and located on the light transmission path of the first attenuator.

[0007] In one embodiment, the first attenuator is a reflective attenuator, and the second attenuator is an absorptive attenuator.

[0008] In one implementation, The reflectivity of the first attenuator is 99%; And / or, the transmittance of the second attenuator is 0.01%; And / or, the reflection angle of the first attenuator is between 20° and 30°.

[0009] In one embodiment, the power adjustment assembly further includes a light-absorbing element disposed on the mounting plate and located on the reflective path of the first attenuator.

[0010] In one embodiment, the power adjustment assembly further includes a sleeve and a lifting bracket, the lifting bracket being disposed on the mounting plate, the first attenuator and the second attenuator being disposed on the sleeve, the sleeve being disposed on the lifting bracket, and the lifting bracket being used to adjust the height of the sleeve.

[0011] In one embodiment, the distance between the power adjustment component and the fixing component is not less than 100mm.

[0012] In one embodiment, the laser collimation and adjustment device further includes a power tester, which is located on the side of the power adjustment component away from the fixed component. The power tester is movably connected to the mounting plate, allowing the power tester to move into or out of the laser's output path.

[0013] In one embodiment, the laser collimation and adjustment device further includes a laser receiving plate, which is disposed on the mounting plate and located on the side of the power adjustment component away from the fixed component. The laser receiving plate is used to receive the laser emitted by the power adjustment component, and the camera is used to capture the light spot on the laser receiving plate. Alternatively, the camera may be located on the side of the power adjustment assembly opposite to the fixed assembly, for receiving and capturing light spots.

[0014] In one embodiment, the fixing assembly includes a fixing frame and a clamping member, the clamping member being rotatably connected to the fixing frame, the clamping member and the fixing frame enclosing a clamping space for fixing the laser.

[0015] The technical solution of this invention fixes the laser with a fixing component. The laser emitted by the laser is first reduced in energy by a power adjustment component before the camera receives the laser spot. This avoids damage to the camera due to excessive energy of the laser spot, ensuring the safety and measurement accuracy of collimation adjustment. After receiving the laser spot, the camera displays the laser spot on the display screen to facilitate the measurement of the laser size. Attached Figure Description

[0023] Please refer to the reference. Figures 1 to 4 As shown, the present invention proposes a laser collimation and adjustment device 100, which includes a mounting plate 1, a fixing component 2, a power adjustment component 3, a camera 6, and a display. The fixing component 2 is disposed on the mounting plate 1 and is used to fix the laser 7. The power adjustment component 3 is disposed on the mounting plate 1 and is located on the light output path of the laser 7, and is used to adjust the light intensity of the laser emitted by the laser 7. The camera 6 is disposed on the mounting plate 1 and is used to capture the light spot of the laser emitted by the power adjustment component 3. The display is electrically connected to the camera 6 and displays the light spot captured by the camera 6.

[0024] In this embodiment, the mounting plate 1 serves as a support platform for mounting other components, allowing the laser collimation and adjustment device 100 to be modularly configured for ease of use. The fixing component 2 positions and fixes the laser 7 to be adjusted, ensuring its fixed position and facilitating collimation adjustment of the lenses on the laser 7. The power adjustment component 3, mounted in the middle section of the mounting plate 1 with its optical center coaxially aligned with the optical axis of the laser 7 and located on the laser 7's output path, receives the original high-power laser beam emitted by the laser 7 and attenuates its intensity to a safe level. The camera 6 captures real-time images of the laser spot emitted by the power adjustment component 3. The display is electrically connected to the camera 6 via wired or wireless means, receiving and displaying the digital image signals transmitted by the camera 6.

[0025] Specifically, during collimation, the high-power-density laser beam emitted from laser 7 first enters power adjustment component 3, where the laser power density is reduced according to a preset attenuation ratio. The attenuated laser beam exits from power adjustment component 3, forming a light spot. Camera 6 captures the light spot and magnifies it for display on a monitor, allowing the operator to observe the light spot in real time. Optionally, the light spot captured by camera 6 can be directly displayed on the monitor, or it can be converted into a grayscale image data stream through photoelectric conversion and analog-to-digital conversion and transmitted to the monitor. The monitor displays the grayscale distribution map of the light spot in real time with a visual interface, allowing the operator to directly observe the morphological characteristics of the light spot, including size and roundness; or analyze the number of pixels that meet the grayscale characteristics of the light spot through software to determine the size and roundness of the light spot by its edges.

[0026] Understandably, this embodiment pre-attenuates the laser power using the power adjustment component 3, reducing the power density of the emitted light spot to the milliwatt or even microwatt level, thus avoiding the risk of thermal damage to the receiving fixture during subsequent light spot reception. Operators can observe the light spot image in real-time and intuitively through a display, and perform collimation adjustments on the laser 7. Simultaneously, image grayscale values ​​can be extracted using software algorithms to identify the number of light spot pixels and edge pixel coordinates, accurately calculating parameters such as light spot size and roundness, achieving software-based quantitative collimation, and improving the collimation adjustment efficiency and reliability of the high-power laser 7.

[0027] In actual implementation, the laser 7 is equipped with a rotatable collimating lens module.

[0028] In embodiments of the present invention, such as Figures 1 to 2 As shown, the power adjustment component 3 includes a first attenuator 31 and a second attenuator 32. The second attenuator 32 is disposed on the side of the first attenuator 31 away from the fixing component 2 and is located on the light transmission path of the first attenuator 31.

[0029] In this embodiment, the first attenuator 31 and the second attenuator 32 are arranged sequentially along the laser transmission direction and optically coaxial. The laser undergoes dual attenuation through the first attenuator 31 and the second attenuator 32, significantly reducing the laser power and ensuring that the laser power remains within the tolerance range of the camera 6 or the receiving fixture. Simultaneously, the first attenuator 31 and the second attenuator 32 share the power attenuation pressure, extending the service life of the power adjustment assembly 3. The cooperation of the first attenuator 31 and the second attenuator 32 improves the power adjustment range and accuracy, effectively reducing the risk of damage to the camera 6 or the receiving fixture. The first attenuator 31 and the second attenuator 32 achieve laser reflection or absorption by depositing multiple layers of dielectric or metal films on a transparent substrate such as glass or quartz.

[0030] In an embodiment of the present invention, the first attenuator 31 is a reflective attenuator, and the second attenuator 32 is an absorptive attenuator. The center of the first attenuator 31 is located on the optical axis of the laser 7, and the second attenuator 32 is disposed on the light-transmitting side of the first attenuator 31, covering the transmitted beam cross-section of the first attenuator 31. The original laser beam emitted by the laser 7 is incident on the first attenuator 31, which splits the laser beam into two paths: one is reflected light, and the other is transmitted light. The transmitted light passes through the first attenuator 31 along the original optical axis and enters the second attenuator 32. The second attenuator 32 absorbs part of the transmitted light, attenuating the transmitted light and reducing the laser power density to within the safe threshold range of the camera 6 or the receiving fixture. It can be understood that the first attenuator 31 first deflects and reflects most of the light energy, retaining only a small amount of transmitted light, and the second attenuator 32 then attenuates the transmitted light, effectively preventing the camera 6 or the fixture from being damaged due to light intensity overload.

[0031] Understandably, setting the first attenuator 31 as a reflective attenuator can prevent it from absorbing too much energy and affecting its lifespan. Setting the second attenuator 32 as an absorptive attenuator can prevent the formation of a reflected light path between the second attenuator 32 and the first attenuator 31, thus avoiding interference with the test.

[0032] In actual implementation, the second attenuator 32 is located on the side of the first attenuator 31 away from the laser 7. The second attenuator 32 with different attenuation rates can be replaced according to the laser power level to achieve modular debugging.

[0033] In embodiments of the present invention, such as Figures 1 to 2 As shown, the reflectivity of the first attenuator 31 is 99%. When the laser hits the first attenuator 31, 99% of the total energy of the reflected light deviates from the main optical axis, and 1% of the total energy of the transmitted light passes through the first attenuator 31 along the original optical axis and enters the second attenuator 32.

[0034] Optionally, the transmittance of the second attenuator 32 is 0.01%. In this embodiment, based on its absorption characteristics, the second attenuator 32 limits the transmittance of the laser light projected onto it to 0.01%, that is, only 0.01% of the light energy incident on the second attenuator 32 is allowed to pass through, while the remaining 99.99% is absorbed.

[0035] Optionally, the reflection angle of the first attenuator 31 is between 20° and 30°. In this embodiment, the reflection angle of the first attenuator 31 is limited to 20° to 30°. This ensures that the reflected light path and the transmitted light path of the first attenuator 31 are fully separated to avoid stray light interference, while compressing the layout of the power adjustment component 3, making the laser collimation and adjustment device 100 more compact.

[0036] In an embodiment of the present invention, the sleeve 34 further includes a light-absorbing element 33, which is disposed on the mounting plate 1 and located on the reflective path of the first attenuator 31.

[0037] In this embodiment, the light-absorbing element 33 is located on the reflected light path of the first attenuator 31, ensuring that the reflected light beam from the first attenuator 31 can be incident on the light-absorbing element 33. The first attenuator 31 separates the incident laser into a transmitted beam and a reflected beam according to the beam splitting ratio. The reflected beam, which accounts for the majority of the energy, deviates from the principal optical axis and is projected onto the light-absorbing element 33. The light-absorbing element 33 absorbs the reflected high-energy beam, preventing it from escaping to other areas of the device. The arrangement of the light-absorbing element 33 prevents the high-energy beam reflected by the first attenuator 31 from affecting the safety of the laser collimation and adjustment device 100 and its surrounding environment, and prevents damage caused by reflected light irradiating the camera 6 or the operator.

[0038] In practical implementation, the main body of the light-absorbing component 33 is a metal shell structure, such as aluminum alloy or copper alloy. Its inner cavity wall is coated with a high-absorption optical coating through anodizing, spraying, or sintering processes. The inner cavity geometry is designed as a conical, cylindrical, or honeycomb structure to increase the effective absorption area and promote multiple reflections and absorption of the light beam. Through physical isolation and energy dissipation, the light-absorbing component 33 prevents the reflected light from forming stray light that could affect the imaging and spot measurement accuracy of the camera 6.

[0039] In embodiments of the present invention, such as Figures 1 to 3 As shown, the power adjustment assembly 3 also includes a sleeve 34 and a lifting bracket 35. The lifting bracket 35 is mounted on the mounting plate 1. The first attenuator 31 and the second attenuator 32 are mounted on the sleeve 34. The sleeve 34 is mounted on the lifting bracket 35. The lifting bracket 35 is used to adjust the height of the sleeve 34.

[0040] In this embodiment, the sleeve 34 is a cylindrical optical lens barrel. Inside, a first attenuator 31 and a second attenuator 32 are sequentially fixed by spacers or pressure rings. These two attenuators are spaced apart along the axis of the sleeve 34 and are optically coaxial, facilitating their insertion into the laser's output path. The sleeve 34 encapsulates the first attenuator 31 and the second attenuator 32 as independent optical modules, protecting them from contamination and damage, and ensuring their alignment to prevent attenuation performance degradation due to vibration. The sleeve 34 can be detachably mounted to the top of the lifting bracket 35 using a clamp or flange structure. The lifting bracket 35 has a threaded joint and a guide rail slider mechanism inside. By rotating the adjustment handwheel, the top end is moved vertically relative to the mounting plate 1, thereby synchronously raising and lowering the sleeve 34 and its internal first and second attenuators 31 and 32.

[0041] Understandably, the limiting position of the sleeve 34 ensures that the coaxiality and spacing of the first attenuator 31 and the second attenuator 32 remain constant, eliminating the need for adjustment and reducing assembly steps during use. The lifting bracket 35 suspends and supports the sleeve 34 in the laser's output optical path, and can move the sleeve 34 vertically. During adjustment, the operator drives the adjustment mechanism of the lifting bracket 35 according to the height of the laser's output center, raising and lowering the sleeve 34 until the center of the first attenuator 31 coincides with the center of the laser beam, completing the optical path alignment. The lifting bracket 35 can adjust the center height of the first attenuator 31 and the second attenuator 32, making the first attenuator 31 and the second attenuator 32 compatible with lasers 7 at different installation heights, improving the device's versatility and assembly efficiency. The horizontal position of the lifting bracket 35 is aligned with the position of the laser 7 fixed on the fixing assembly 2 during installation.

[0042] In an embodiment of the present invention, a slide rail is provided on the mounting plate 1, the slide rail is arranged parallel to the light output path of the laser 7, and the lifting bracket 35 is provided on the slide rail.

[0043] In this embodiment, a slide rail is fixed to the surface of the mounting plate 1. The slide rail is a linear guide rail structure, and its guide axis is arranged parallel to the light output path of the laser 7. The lifting bracket 35 is slidably connected to the slide rail through a slider or slot structure, so that the lifting bracket 35 slides back and forth along the slide rail.

[0044] Understandably, the sliding engagement between the slide rail and the lifting bracket 35 allows the power adjustment component 3 to have axial position adjustability while maintaining height alignment. This enables the adjustment of the distance between the first attenuator 31 and the second attenuator 32 and the laser 7, based on the laser 7's beam divergence angle or testing requirements. When the laser 7 has a large beam aperture or a small beam divergence angle, the power adjustment component 3 can be moved backward to avoid beam truncation; when maximizing light energy utilization or conducting near-field testing is required, the power adjustment component 3 can be moved forward closer to the laser 7.

[0045] Meanwhile, the sliding rails also allow the operator to move the lifting bracket 35 away from the fixed component 2 when installing or removing the laser 7 or adjusting the collimation, thus avoiding interference with the operator's operation.

[0046] During actual adjustment, the lifting bracket 35 can be driven manually or electrically to move along the slide rail, causing the sleeve 34 and its internal first attenuator 31 and second attenuator 32 to move closer to or further away from the laser 7, thereby changing the axial distance between the power adjustment component 3 and the laser 7's output port. A scale or limit stop can be installed on the slide rail to achieve quantitative position adjustment and locking.

[0047] In embodiments of the present invention, such as Figures 1 to 2As shown, the distance between the power adjustment component 3 and the fixing component 2 is not less than 100mm.

[0048] In this embodiment, the power adjustment component 3 and the fixing component 2 are arranged in a straight line along the light output path of the laser 7, and the minimum distance between the power adjustment component 3 and the fixing component 2 is not less than 100mm. This distance refers to the distance along the light output path of the laser 7 from the light output port end face of the laser 7 in the fixing component 2 to the light incident surface of the first attenuator 31 in the power adjustment component 3.

[0049] In practice, the fixing component 2 and the power adjustment component 3 are spaced a certain distance apart to form an unobstructed operating area. The length of the operating area is not less than 100mm to allow the operator's hands or tools to freely extend into it. The collimating lens of the laser 7 is usually located at the output end of the laser 7, between the fixing component 2 and the power adjustment component 3. When the laser 7 is initially fixed but not yet precisely collimated, the operator can directly touch and rotate the adjustment ring of the collimating lens through this operating channel to fine-tune the beam divergence angle and focal position. This avoids interference from the power adjustment component 3 in the collimating lens adjustment, allowing the operator to independently complete the collimation adjustment without repeatedly disassembling and reassembling the power adjustment component 3, thus improving collimation efficiency and convenience.

[0050] In an embodiment of the present invention, the laser collimation and adjustment device 100 further includes a power tester 4, which is located on the side of the power adjustment component 3 away from the fixed component 2. The power tester 4 is movably connected to the mounting plate 1, so that the power tester 4 can move into or out of the light output path of the laser 7.

[0051] In this embodiment, the power tester 4 is located on the light-emitting side of the power adjustment component 3 and is movably connected to the mounting plate 1 via a movable connection mechanism. Optionally, the power tester 4 is slidably or rotatably connected to the mounting plate 1 via a linear slide rail or a rotating swing arm.

[0052] Understandably, when the power tester 4 is slidably mounted on the mounting plate 1, with its sliding direction forming an angle with the light output path of the power adjustment component 3, it can reciprocate along the slide rail under external force to move into or out of the light output path of the laser 7. Alternatively, the power tester 4 can be rotatably mounted on the mounting plate 1 via a rotating shaft, and external force can be used to drive the power tester 4 to swing, thus moving the power tester 4 into or out of the light output path.

[0053] When power measurement is required, the operator moves the power tester 4 into the light output path of the laser 7, ensuring the probe end of the power tester 4 is precisely aligned with the laser. At this point, the laser beam emitted from the power adjustment component 3 is fully incident on the probe end, and the power tester 4 measures the laser power. When it is necessary to observe the spot shape or perform collimation adjustments, the operator moves the power tester 4 out of the light path to avoid obstructing the laser and preventing it from blocking the subsequent imaging of the camera 6 or the laser receiver 5. The moved position can be fixed by a limit pin or magnetic attraction to prevent the power tester 4 from accidentally moving into the light output path due to vibration.

[0054] The power tester 4 integrates quantitative laser power measurement and beam spot observation into the laser collimation and adjustment device 100. When measuring power, the power tester 4, moved into the optical path, can directly acquire the power value of the beam after attenuation by the power adjustment component 3. This is used to calibrate the attenuation ratio or monitor the stability of the laser output power, preventing damage to the camera 6 or receiving fixture due to the power of the beam emitted from the power adjustment component 3 still being outside the tolerance range of the camera 6 or receiving fixture. When performing beam spot analysis, removing the power tester 4 allows for quick switching to beam spot measurement without disassembling or realigning the optical path, improving adjustment efficiency.

[0055] In embodiments of the present invention, such as Figure 1 As shown, the laser collimation and adjustment device 100 also includes a laser receiving plate 5, which is mounted on the mounting plate 1 and located on the side of the power adjustment component 3 away from the fixed component 2. The laser receiving plate 5 is used to receive the laser emitted by the power adjustment component 3, and the camera 6 is used to photograph the light spot on the laser receiving plate 5. In this embodiment, the laser receiving plate 5 is mounted on the mounting plate 1 and located on the light-emitting side of the power adjustment component 3. The receiving surface of the laser receiving plate 5 is perpendicular to the laser optical axis and faces the light-emitting end of the power adjustment component 3. The camera 6 is fixed to the mounting plate 1, with its lens optical axis forming a certain angle with the laser optical axis, and its field of view covering at least the entire light spot area on the laser receiving plate 5. The laser beam, attenuated by the power adjustment component 3, is incident on the surface of the laser receiving plate 5, forming a visible light spot or a near-infrared fluorescent light spot. The light spot appears as a static image with a certain size, shape, and energy distribution on the surface of the receiving plate. The camera 6 takes a two-dimensional image of the light spot from the side or front of the laser receiving plate 5 at an angle, and converts the optical signal into an electrical signal for transmission to the display.

[0056] Understandably, the laser receiver plate 5 is designed to prevent the camera 6 from directly receiving the laser beam, effectively preventing problems such as sensor saturation or damage that might occur if the camera 6 directly receives the laser. This design is suitable for observing high beam quality or high power density lasers. Optionally, the surface of the receiver plate can be calibrated to facilitate intuitive reading of the spot diameter and positional deviation, enabling rapid collimation.

[0057] In practical implementation, the laser receiving plate 5 can be made of diffuse reflective materials such as ceramics, barium sulfate coatings, or special engineering plastics to uniformly scatter the incident laser energy. When capturing the light spot, the operator can optimize the clarity and contrast of the light spot image by adjusting the focal length, exposure time, and gain parameters of the camera 6.

[0058] In embodiments of the present invention, such as Figure 2 As shown, the camera 6 is located on the side of the power adjustment component 3 away from the fixed component 2, and is used to receive and capture light spots.

[0059] In this embodiment, camera 6 is directly mounted on the light-emitting side of power adjustment component 3, with its receiving end located on the laser optical axis. It can directly receive the laser beam emitted by power adjustment component 3 and capture the light spot. Understandably, the lens of camera 6 focuses the laser spot onto the sensor's photosensitive unit, forming a direct digital image of the original light spot, thereby improving the accuracy of measuring spot characteristics such as size and roundness. The direct imaging mode of camera 6 eliminates the scattering loss and image distortion caused by capturing the light spot through the receiving plate, enabling the true capture of the original shape and size of the laser spot with high measurement accuracy, making it suitable for high-resolution beam quality analysis.

[0060] In practice, the camera's built-in shutter and gain circuitry automatically adjusts the exposure based on the laser intensity, ensuring that the image grayscale values ​​remain within the effective dynamic range. Software algorithms analyze the pixel grayscale distribution of the image, enabling precise analysis of the light spot.

[0061] In embodiments of the present invention, such as Figure 4 As shown, the fixing component 2 includes a fixing frame 21 and a clamping member 22. The clamping member 22 is rotatably connected to the fixing frame 21. The clamping member 22 and the fixing frame 21 enclose a clamping space 23, which is used to fix the laser 7.

[0062] In this embodiment, the fixing frame 21 serves as a base and is mounted on the mounting plate 1. The fixing frame 21 has a first limiting groove that matches the outer contour of the laser 7, and one side of the first limiting groove has a notch. One end of the clamping member 22 is rotatably connected to the fixing frame 21, and the other end of the clamping member 22 is a free end that can swing between the open and closed positions. When the clamping member 22 rotates to the closed position, it covers the notch of the first limiting groove, forming a clamping space 23 with the first limiting groove, thus fixing the laser 7. When clamping the laser 7, the operator first rotates the clamping member 22 outward around the axis to open it, exposing the clamping space 23. Then, the laser 7 is placed in the first limiting groove of the fixing frame 21, with the light-emitting end facing the power adjustment component 3. Then, the clamping member 22 is rotated so that it abuts against the laser 7, limiting the laser 7 in the clamping space 23. The clamping space 23 formed by the rotatable clamping member 22 and the fixed frame 21 enables the laser 7 to be quickly installed and removed. Operators can install and remove the laser 7 without disassembling the entire fixed assembly 2, which reduces the installation time of the laser 7 and improves the debugging efficiency.

[0063] Optionally, the free end of the clamping member 22 can be detachably connected to the fixing frame 21 via a threaded locking handle, quick-release lever, or elastic buckle. After applying a locking force, the clamping member 22 and the fixing frame 21 together provide radial restraint to the laser 7 housing. Simultaneously, static friction is generated at the contact surface to prevent axial displacement of the laser 7. Utilizing the restraint of the fixing component 2, the optical axis of the laser 7 is aligned with the preset reference optical axis of the fixing frame 21, allowing the laser 7 to be better aligned with the power adjustment component 3.

[0064] Optionally, the clamping member 22 is pivotally connected to the fixing frame 21 via a hinge shaft, pin shaft, or rotating snap-fit ​​structure, forming a rotatable connection. The clamping member 22 is also provided with a second limiting groove that matches the outer contour of the laser 7. The second limiting groove and the first limiting groove together enclose a clamping space 23 to further improve the fixing effect on the laser 7.

[0065] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
