Description

Technical Field

[0001] This invention relates to the field of semiconductor laser technology, and more specifically to an automatic coupling device for fast-axis beams of microchannel laser arrays. Background Technology

[0002] With the rapid development of laser technology, microchannel semiconductor laser arrays have been widely adopted in many key fields such as industrial processing, medical diagnostics, lidar, and national defense due to their significant advantages such as high power density, miniaturization, high efficiency, and long lifespan. However, while achieving high power output, beam quality control (especially beam coupling in the fast axis direction) has become a core technical bottleneck restricting the full realization of the performance of microchannel semiconductor laser arrays and their large-scale industrial application.

[0003] Since there is currently no dedicated equipment for automatic beam coupling along the fast axis of microchannel semiconductor laser arrays, the commonly used coupling method is as follows: the fast-axis collimating lens is picked up with tweezers and placed at the lens vacuum nozzle position at one end of the six-axis adjustment. The single microchannel laser bar is powered on, and the position of the fast-axis collimating lens is adjusted through the six-axis adjustment frame. After adjusting to the optimal position for fast-axis beam coupling, the lens is manually attached to the front end of the laser using a glue needle dipped in UV glue. The lens is then firmly bonded by UV curing, and finally, the coupled single bars are assembled into an array.

[0004] Existing coupling tools are relatively simple. From the perspectives of production efficiency and coupling accuracy, manual coupling relies entirely on the operator's experience and fine manual control. Operators need to visually observe and manually adjust the lens position, which not only takes several minutes per coupling cycle, making it difficult to meet the cycle time requirements of mass production, but also leads to significant fluctuations in coupling accuracy due to differences in the skill level of different operators and changes in the fatigue level of the same operator after long-term operation. Data shows that the accuracy deviation of manual coupling is usually greater than ±5μm, with a consistency pass rate of less than 70%, directly affecting the laser's beam focusing performance and output power stability, and consequently leading to a decrease in the working accuracy of downstream equipment.

[0005] Furthermore, existing coupling methods pose significant risks of physical damage and contamination. Fast-axis collimating lenses often utilize high-transmittance optical glass, and their surface finish and structural integrity are crucial for beam coupling effectiveness. During manual gripping, operators struggle to precisely control the gripper force; too loose a grip can cause the lens to slip, while too tight a grip can lead to edge chipping or surface indentations. Simultaneously, oils from hand skin and dust from the air easily adhere to the lens surface during manual operation, forming stubborn stains that reduce beam transmittance and even generate stray light, affecting the laser's output quality. Industry statistics indicate that the breakage rate of manually gripped lenses is as high as 8%, and the defect rate due to contamination exceeds 12%, significantly increasing production costs and material waste.

[0006] In the curing process of fast-axis lenses, existing operating methods also have many shortcomings. When manually dispensing adhesive, operators find it difficult to precisely control the amount and location of the adhesive, easily resulting in excessive adhesive application leading to over-adhesion between the lens and substrate, or insufficient adhesive application resulting in insufficient bonding strength. Furthermore, the irradiation position of the UV curing lamp relies entirely on manual adjustment, often resulting in misalignment of the irradiated area and uneven irradiation intensity, leading to inconsistent cross-linking of the cured adhesive. This not only causes weak lens adhesion, making the lens prone to displacement due to vibration or temperature changes during subsequent use, but also leads to uneven stress distribution on the lens surface due to uneven adhesive curing, causing optical distortion. Additionally, appearance defects in the bonding area affect the product's appearance pass rate, reducing its market competitiveness.

[0007] Furthermore, the manual power-on operation during the coupling process poses a significant risk of device damage. The electrode structure of the laser bar is delicate and its surface is fragile. Manually controlling the contact force and angle between the electrode probe and the bar electrodes makes it difficult to precisely control the contact. Excessive force can cause wear on the electrode layer on the bar surface and even damage the microchannel heat dissipation structure; insufficient force can result in poor contact, arcing, and electrode burnout, rendering the entire laser bar unusable. Industry data shows that the damage rate of the bar due to manual power-on operation exceeds 5%, directly causing high device losses and further exacerbating production cost pressures.

[0008] Faced with the aforementioned problems of low production efficiency, poor coupling accuracy, high device damage rate, and insufficient product consistency, the industry urgently needs a technical solution that can achieve full automation of the fast axis coupling process.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0028] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are the horizontal direction (i.e., X direction), the front and back directions are the vertical direction (i.e., Y direction), and the up and down directions are the vertical direction (i.e., Z direction).

[0029] like Figure 1 , Figure 3 , Figure 2 , Figure 4 and Figure 5 As shown, an automatic beam coupling device for a microchannel laser 211 stacked array 21 fast axis includes an optical platform 1, on which are arranged an array adjustment unit 2, an electric power supply unit 3, a UV curing unit 4, a lens adjustment unit 5, a lens material tray 61, a dispensing unit 7, a near-field detection unit 81, and a far-field detection unit 82.

[0030] like Figure 1 , Figure 3 , Figure 2 , Figure 4 and Figure 6 As shown, the optical platform 1 is equipped with a stacking adjustment unit 2, which includes a stacking fixing base 22 for mounting a stacked array 21. The stacked array 21 is composed of multiple microchannel lasers 211 stacked together. The stacked array 21 is mounted and fixed on the stacking fixing base 22, with the light-emitting side of the stacked array 21 facing forward and the power-receiving side facing left. The stacked array 21 can move vertically under the action of the stacking adjustment unit 2. A power-applying unit 3 is located on the left side of the stacking adjustment unit 2 on the optical platform 1. The electrode probe 31 of the power-applying unit 3 faces right (i.e., the power-receiving side of the stacked array 21), and the power-applying unit 3 can move the electrode probe 31 left and right. During operation, the stacked array 21 moves up and down under the drive of the stacked array adjustment unit 2, thereby aligning each microchannel laser 211 with the electrode probe 31 of the power-on unit 3 one by one; the power-on unit 3 drives the electrode probe 31 to move left and right, thereby realizing the connection and disconnection of the circuit.

[0031] As one specific implementation method, such as Figure 7 and Figure 12As shown, the array adjustment assembly 2 in this embodiment includes a first vertical linear slide 23 arranged vertically. The array fixing seat 22 is detachably fixed to the slide of the first vertical linear slide 23, and the array 21 is detachably fixed to the array fixing seat 22. The power-on assembly 3 includes a power-on slide cylinder 32. The cylinder body of the power-on slide cylinder 32 is detachably fixed to the optical platform 1. The slider of the power-on slide cylinder 32 is provided with a power-on bracket for mounting the electrode probe 31. The power-on bracket includes a first connecting block 331 with an L-shaped structure. The horizontal part of the first connecting block 331 is detachably fixed to the slider of the power-on slide cylinder 32.

[0032] Furthermore, such as Figure 7 As shown, the stacking array adjustment unit 2 further includes a first longitudinal linear slide 24 and a first transverse linear slide 25. Driven by the first transverse linear slide 25, the first longitudinal linear slide 24, and the first vertical linear slide 23, the stacking array 21 can move along the front-back direction, the left-right direction, and the up-down direction, thereby adjusting the spatial position of the stacking array 21. The first transverse linear slide 25, the first longitudinal linear slide 24, and the first vertical linear slide 23 are all electric slides, allowing for adjustments to the spatial position of the stacking array 21 as needed during operation.

A first transverse linear slide 25 is provided on the slide base of the first longitudinal linear slide 24, and the first vertical linear slide 23 is fixedly connected to the slide base of the first transverse linear slide 25 via a connecting support 26.

[0034] By setting the first transverse linear slide 25 and the first longitudinal linear slide 24, the stacking adjustment unit 2 can be adapted to stacking arrays 21 of different models and sizes, thereby improving the versatility of the entire coupling device.

[0035] Furthermore, in order to facilitate the adjustment of the position of the electrode probe 31 so that its position meets the requirements, such as... Figure 12As shown, a first power-adjusting slide 34 arranged laterally and a second power-adjusting slide 35 arranged longitudinally are provided between the power-on support and the power-on slide cylinder 32. Both the first power-adjusting slide 34 and the second power-adjusting slide 35 are manual slides. By adjusting the first power-adjusting slide 34 and the second power-adjusting slide 35, the position of the electrode probe 31 can be adjusted so that when the power-on slide cylinder 32 extends, the electrode probe 31 is in contact with the power-on side of the microchannel laser 211, avoiding problems such as poor contact or damage to the microchannel laser 211.

[0036] In one specific implementation, in this embodiment, the first power-adjusting slide 34, arranged longitudinally, is mounted on the slider of the power-adjusting slide cylinder 32. The second power-adjusting slide 35 is mounted on the slide base of the first power-adjusting slide 34. The power-adjusting bracket is detachably fixed on the slide base of the second power-adjusting slide 35.

The first curing adjustment slide 42 is arranged longitudinally, the second curing adjustment slide 43 is arranged transversely, and the third curing adjustment slide 44 is arranged vertically. Driven by the first curing adjustment slide 42, the second curing adjustment slide 43, and the third curing adjustment slide 44, the UV lamp 41 can move back and forth, left and right, and up and down, thereby adjusting the spatial position of the UV lamp 41 so that the light-emitting end of the UV lamp 41 is directly facing the coupled microchannel laser 211 in the stacked array 21. The first curing adjustment slide 42, the second curing adjustment slide 43, and the third curing adjustment slide 44 are all manual slides.

[0039] In one specific embodiment, the first curing adjustment slide 42 is detachably fixed to the optical platform 1. The second curing adjustment slide 43 is disposed on the movable side of the first curing adjustment slide 42, and a detachable curing bracket 45 is disposed on the movable side of the second curing adjustment slide 43. The curing bracket 45 has an L-shaped structure, and the horizontal portion of the curing bracket 45 is detachably fixed to the movable side of the second curing adjustment slide 43. The third curing adjustment slide 44 is detachably fixed to the upper end of the vertical portion of the curing bracket 45.

The connecting shaft 47 is clamped and fixed between the main board body and the clamping block. Preferably, the main board body and the clamping block are respectively provided with clamping grooves for accommodating the connecting shaft 47.

The second mounting base 522 includes a second vertical plate, and a second horizontal plate extending perpendicularly to the second vertical plate away from the first swing slide 521 is provided at the upper end of the second vertical plate. The second vertical plate is detachably fixedly connected to the swing side of the first swing slide 521. A second swing slide 523 is provided on the lower side of the second horizontal plate, and the swing axis of the second swing slide 523 extends laterally. A detachable third mounting base 524 is fixedly provided on the swing side of the second swing slide 523. A detachable third swing slide 525 is fixedly provided on the third mounting base 524.

A detachable fourth mounting base 526 is fixedly provided on the swing side of the third swing slide 525. The fourth mounting base 526 includes an inclined first plate, which is detachably fixed to the swing side of the third swing slide 525. The front end of the first plate is provided with a second plate extending horizontally away from the third swing slide 525. The second plate is provided with a pickup component 53 for picking up the fast axis collimating lens 62.

[0045] Driven by the second transverse linear slide 511, the second longitudinal linear slide 512, the second vertical linear slide 513, the first swing slide 521, the second swing slide 523, and the third swing slide 525, the fast-axis collimating lens 62 has six degrees of freedom: transverse translation, longitudinal translation, vertical translation, transverse rotation, longitudinal rotation, and vertical rotation. It can quickly adjust the position of the fast-axis collimating lens 62 to find the optimal coupling position.

[0046] The second transverse linear slide 511, the second longitudinal linear slide 512, the second vertical linear slide 513, the first swing slide 521, the second swing slide 523, and the third swing slide 525 are all electric slides.

[0047] In one specific embodiment, a first mounting base 514 is provided between the second longitudinal linear slide 512 and the second vertical linear slide 513.

The fixed claw 531 is detachably fixed to the fourth mounting base 526. The lower ends of the fixed claw 531 and the movable claw 532 are pickup ends used to pick up the fast-axis collimating lens 62. A push cylinder 533 is provided on the fixed claw 531 below the hinge point, and a pickup spring 534 is provided between the fixed claw 531 and the movable claw 532 above the hinge point. When the piston rod of the push cylinder 533 extends, the lower end of the movable claw 532 (i.e., the pickup end) rotates outward (with the side away from the fixed claw 531 as the outward side) under the pushing action of the push cylinder 533. At the same time, the pickup spring 534 is compressed, and the pickup component 53 is in the open state. When the piston rod of the push cylinder 533 retracts, the lower end (i.e., the pickup end) of the movable claw 532 rotates inward under the elastic recovery of the pickup spring 534, thereby clamping the fast axis collimating lens 62 to be picked up.

[0070] An operation method for an automatic beam coupling device for a microchannel laser array 211 fast axis 21 includes the following steps: First, the stacked array 21 to be coupled to fast axis beams is installed onto the stacked array fixing base 22 of the stacked array adjustment unit 2.

[0071] Second, turn on the start switch, and the stacked array adjustment unit 2 will run automatically, moving the stacked array 21 to the power-on position. At this time, the electrode probe 31 of the power-on unit 3 will come into contact with the microchannel laser 211 and light up the microchannel laser 211 through the electrode probe 31.

[0072] Third, the lens adjustment unit 5 starts to operate, which drives the pickup component 53 to move automatically above the lens tray 61 and pick up the fast axis collimating lens 62 in the lens tray 61.

[0073] Fourth, the lens adjustment unit 5 moves the fast-axis collimating lens 62 to the incident side of the reflector 911, and picks up the clamping image of the fast-axis collimating lens 62 reflected by the reflector 911 from the detection camera 921, and determines whether the clamping state of the fast-axis collimating lens 62 is incorrect or abnormal. If there is an abnormality, the machine stops and an alarm is triggered; if there is no abnormality, the next step is continued.

[0074] Fifth, the lens adjustment unit 5 moves the fast-axis collimating lens 62 to the front end of the microchannel laser 211. At this time, the laser emitted by the microchannel laser 211 is compressed in the fast-axis direction by the fast-axis collimating lens 62, and then enters the SAC lens 752 for slow-axis beam compression. Then, it is split into two laser beams, a far-field beam and a near-field beam, by the beam splitter 816. The near-field beam is emitted from the first light-emitting side of the beam splitter 816 and enters the near-field detection camera 815 for near-field detection. The far-field beam is emitted from the second light-emitting side of the beam splitter 816 and enters the far-field detection camera 825 for far-field detection.

[0075] Sixth, the lens adjustment unit 5 adjusts the position of the fast-axis collimating lens so that both the far-field beam and the near-field beam of the microchannel laser 211 are coupled to the optimal position, and the device automatically records the coupling position parameters.

[0076] Seventh, the energized slide cylinder 32 retracts, the microchannel laser 211 is de-energized, and the pickup component 53 moves the fast axis collimating lens 62 to a clearance position, thereby providing space for the dispensing operation of the dispensing unit 7.

[0077] Eighth, the dispensing unit 7 operates, the glue gun 744 moves to the front end of the microchannel laser 211, and the glue gun 744 evenly applies ultraviolet glue to both ends of the microchannel laser 211.

[0078] Ninth, according to the coupling position parameters recorded in step six, lens adjustment assembly 5 moves the fast-axis collimating lens 62 to the front end of the microchannel laser 211, making the fast-axis collimating lens 62 contact the UV adhesive at the front end of the microchannel laser 211. Then, UV curing assembly 4 operates, irradiating the adhesive application site of the microchannel laser 211 with UV lamp 41 for 1-3 minutes to cure the UV adhesive until the fast-axis collimating lens 62 is firmly bonded to the microchannel laser 211. This completes the fast-axis beam coupling operation of a single microchannel laser 211.

[0079] Tenth, the stacking adjustment unit 2 moves the stacking array 21 upward by a height equal to the thickness of the microchannel laser 211, and repeats the operations from the first to the ninth step to complete the fast-axis beam coupling of the second microchannel laser 211, and so on to complete the fast-axis beam coupling of all microchannel lasers 211 in the entire stacking array 21.
