Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a multi-station linkage laser welding machine for eyeglass temples. Background Technology

[0002] As a common device for vision correction and decoration, the precision of the structure and assembly of eyeglasses directly determines the product quality and user experience. The connection between the temples and the frame is the core of the assembly. Laser welding has become the mainstream processing technology for this part due to its advantages of small heat-affected area and high welding strength.

[0003] When repairing eyeglasses with broken temples, existing welding equipment often uses a single clamp structure for its positioning components, which can only fix the frame or temple on one side. Furthermore, the clamps are mostly made of rigid materials, making them prone to scratching and deformation of the frame surface during clamping. Additionally, traditional positioning seats are mostly fixed installation structures, unable to be adjusted to accommodate different eyeglass sizes. When welding multiple eyeglass models, frequent clamp changes are necessary, which is not only cumbersome but also reduces production efficiency. The positioning accuracy is also easily affected by the frequency of clamp changes, leading to misalignment of the weld seam and impacting the finished product yield. Existing laser welding equipment often uses independent modules for heat dissipation and dust suppression. The heat dissipation device only cools the laser emission module and does not protect the workpiece in the welding area. High temperatures can easily cause thermal deformation of the plastic or metal parts of the eyeglass frame and temples. At the same time, dust suppression devices are mostly external fans with poor fume collection and guidance. Metal fumes generated during welding easily adhere to the laser emission head lens, affecting the stability of laser emission. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a multi-station linkage laser welding machine for eyeglass temples, comprising: a base, wherein a power box and a lifting frame assembly are sequentially fixedly installed on the side of the top of the base, and a welding component is installed on the surface of the lifting frame assembly, which is used for adjusting the welding point and for dust reduction and heat dissipation during welding.

[0005] A positioning component is fixedly installed at the middle of the top of the base, and the positioning component is located below the lifting frame assembly and the welding assembly;

[0006] The positioning component includes a positioning seat, a stop strip fixedly installed at the top edge of the positioning seat, a positioning strip fixedly installed on the surface of the positioning seat near the stop strip, a clamping block fixedly installed on the side of the positioning strip, rotating grooves at both ends of the positioning strip, hook-shaped parts rotatably installed on the surface of the positioning strip through the rotating grooves, and clamping parts slidably installed on both sides of the top of the positioning strip. The positioning seat is slidably installed on the top of the base. The position of the positioning seat on the base can be adjusted according to the size of the eyeglasses to be welded, so that the positioning seat is in the working area below the welding component. The eyeglass frame is placed on top of the positioning seat, and the stop strip at the edge provides initial edge restraint for the eyeglass frame, preventing large-scale horizontal displacement. After the eyeglass frame is attached to the stop strip, its edge will first overlap the clamping block, which provides initial support for the eyeglass frame.

[0007] Preferably, the positioning seat is slidably mounted on the top of the base, the clamping block cooperates with the hook-shaped member to support and fix the eyeglass frame, and the clamping member clamps and fixes the temples of the eyeglasses.

[0008] Preferably, the hook-shaped component includes a rotating rod, with a paddle sleeved on the outer surface of the rotating rod. A hook is fixedly installed on the outer surface of the paddle, and a pressing groove is formed inside the hook. When the operator moves the paddle of the hook-shaped component, the rotating rod rotates within the groove of the positioning strip, and the paddle and rotating rod are fixedly connected. The paddle drives the rotating rod to rotate synchronously, causing the hook to flip towards the eyeglass frame. After the hook engages with the corresponding part of the eyeglass frame, its internal pressing groove will fit against the surface of the eyeglass frame. At the same time, because the paddle is frictionally adapted to the positioning strip through the rotating rod, the hook-shaped component will maintain the current engagement angle, cooperating with the clamping block to securely fix the eyeglass frame. Furthermore, the flexible plastic material of the paddle and hook can prevent damage to the surface of the eyeglass frame. The three-layer frame fixing structure, consisting of initial positioning by the stop strip, support by the clamping block, and engagement by the hook-shaped component, along with the temple clamping structure, achieves precise layered fixing of the frame and temples, effectively preventing workpiece displacement during welding, ensuring the accuracy of the welding points, and improving the welding qualification rate.

[0009] Preferably, the rotating rod is rotatably installed inside the hook-shaped component, and the paddle and the hook are both made of flexible plastic material. The paddle is adapted to the positioning strip through friction with the rotating rod.

[0010] Preferably, the clamping component includes a sliding plate, a telescopic rod fixedly mounted on the outer surface of the sliding plate, a positioning plate fixedly mounted on the outer surface of the telescopic rod, baffles fixedly mounted on both sides of the outer surface of the positioning plate, a limiting plate fixedly mounted on the bottom of the baffles, an arc-shaped pad fixedly mounted between the opposite surfaces of the limiting plates, and an extension strip fixedly mounted on the outer surface of the arc-shaped pad. After the frame is fixed, according to the installation position of the temples, the clamping components on both sides of the top of the positioning strip are slid to push the sliding plate to slide on the surface of the positioning strip, adjusting the overall position of the clamping component so that the clamping component is aligned with the area to be clamped on the temples.

[0011] Preferably, the sliding plate is slidably mounted on top of the positioning strip. The baffle, arc pad, and extension strip are all made of flexible plastic, and the extension strip is pressed and fitted with the limiting plate. After adjustment, the telescopic rod extends and retracts, causing the positioning plate to move downward. The baffles on both sides of the positioning plate first limit the temples on both sides, and then the bottom limiting plate fits against the surface of the temples. The arc pad on the opposite side of the limiting plate completely covers the outer surface of the temples, and at the same time, the extension strip on the arc pad is pressed and fitted with the limiting plate, further enhancing the clamping tightness of the temples. Since the baffle, arc pad, and extension strip are all made of flexible plastic, both clamping stability and scratches on the surface coating of the temples can be ensured. The hook-shaped components, including the paddles and latches, as well as the baffles, arc pads, and extension strips of the clamping components, are all made of flexible plastic. This allows them to be adapted to eyeglass frames and temples of different sizes and curvatures, significantly improving the compatibility of the positioning components with different eyeglass models and eliminating the need for frequent changes to the positioning fixture. It also prevents damage such as indentations and scratches on the surface of the eyeglasses during clamping, ensuring the appearance quality of the eyeglasses.

[0012] Preferably, the lifting frame assembly includes a column, a guide slide is mounted on the outer surface of the column, a support rod is fixedly mounted on the outer surface of the guide slide, a drive motor is fixedly mounted on the outer surface of the support rod, and a cooler is rotatably mounted on the bottom of the drive motor. Simultaneously with the laser welding of the welding assembly, the drive motor activates the cooler, and the low-temperature airflow generated by the cooler is delivered to the laser drive module through the curved pipe of the welding assembly. Part of the airflow cools the laser generation module, while the other part is directed towards the welding area through the curved nozzle, achieving rapid removal of welding fumes and real-time heat dissipation of the weld joint. If fine-tuning of the welding point is required during welding, the drive motor can drive the support rod to make a small horizontal displacement, and the column can also drive the guide slide to make slight rises and falls, ensuring the accuracy of the welding trajectory. The lifting frame integrates the drive motor and the air cooler on the frame pole, realizing the synchronous linkage of welding operation and heat dissipation and dust reduction. The airflow generated by the air cooler can cool the core module of the welding component, preventing equipment failure due to overheating, and can also directly act on the welding area to blow away metal fumes and prevent the weld point from oxidizing. At the same time, it reduces the risk of thermal deformation of the eyeglass workpiece, greatly improving the pass rate and aesthetics of the welded products.

[0013] Preferably, the column is fixedly installed on the side of the top of the base, and the frame rod is drivenly connected to the welding assembly. The welding assembly is mounted above the eyeglasses via the frame rod. After the positioning assembly completes the clamping of the eyeglasses workpiece, the power box transmits a drive signal to the lifting frame assembly, the transmission mechanism inside the column is activated, and the guide slide slides precisely downward along the outer surface of the column, simultaneously driving the frame rod and welding assembly to descend until the vertical distance between the welding head of the welding assembly and the point to be welded reaches the preset welding height. The guide slide then stops moving and locks its position. After the vertical height positioning is completed, the drive motor starts, and its output end drives the frame rod to slide laterally along the horizontal guide rail of the guide slide, thereby pulling the guide seat of the welding assembly to move synchronously on the outer surface of the frame rod, achieving precise horizontal alignment of the welding head until the laser emitter is completely aligned with the welding joint between the eyeglass frame and the temple.

[0014] Preferably, the welding assembly includes a laser driving module. A guide seat is fixedly mounted on the surface of the laser driving module. The guide seat is driven and mounted on the outer surface of the frame. A bent pipe is fixedly mounted on the top of the laser driving module and is connected to a cooling fan. A welding head is fixedly mounted on the bottom of the laser driving module. The welding assembly is driven and connected to the frame of the lifting frame assembly via the guide seat. The lifting frame assembly drives the guide seat to slide horizontally along the frame, simultaneously moving the laser driving module synchronously until the welding head at the bottom of the laser driving module is initially aligned with the welding point on the eyeglass frame and temple. Then, the height of the guide seat is adjusted by the column of the lifting frame assembly to achieve precise alignment between the welding head and the welding point.

[0015] Preferably, the welding head includes a connecting seat, which is fixedly installed at the bottom of the laser driving module. A bent air nozzle is fixedly installed on the inner wall of the connecting seat, and a laser emitting head is fixedly installed inside the bent air nozzle. The laser driving module transmits a laser signal to the welding head. The connecting seat of the welding head fixes the position of the laser emitting head, and the laser emitting head accurately emits a laser beam to the welding point, realizing the fusion of the temple and the frame. During this process, the bent pipe continuously delivers cold air from the cooling fan to cool the laser driving module and the welding head as a whole. The bent air nozzle inside the welding head simultaneously sprays airflow, which directly acts on the welding area, blowing away the metal fumes generated during welding, and simultaneously providing localized heat dissipation for the high-temperature weld point. The bent pipe receives the cold air from the cooling fan, which can dissipate heat from the laser generating module inside the laser driving module and the welding head as a whole, preventing the equipment from being damaged by overheating due to continuous operation. At the same time, the bent air nozzle built into the welding head directly blows air to cool the weld point, which can prevent the eyeglass components from deforming due to high temperature and avoid oxidation of the weld point caused by high temperature, ensuring the precision and aesthetics of the welded product.

[0016] This invention provides a multi-station coordinated laser welding machine for eyeglass temples. It has the following beneficial effects:

[0017] (i) This multi-station laser welding machine for eyeglass temples uses a stop bar at the edge to initially limit the edge of the eyeglass frame by placing it on top of the positioning seat, thus preventing large-scale horizontal displacement of the eyeglass frame. After the eyeglass frame is attached to the stop bar, its edge will first overlap the clamping block, which provides initial support for the eyeglass frame.

[0018] (II) This multi-station linkage laser welding machine for eyeglass temples, through the adoption of a three-layer frame fixing structure consisting of a stop bar for initial positioning, a clamping block for support, and a hook-shaped fastening component, as well as an eyeglass temple clamping structure, achieves precise layered fixing of the frame and the temples, effectively preventing workpiece displacement during welding, ensuring the accuracy of the welding points, and improving the welding qualification rate.

[0019] (III) The multi-station linkage laser welding machine for eyeglass temples uses flexible plastic materials for the hook-shaped parts, such as the paddles and hooks, as well as the baffles, arc pads, and extension strips of the clamping parts. This allows it to adapt to eyeglass frames and temples of different sizes and curvatures, greatly improving the compatibility of the positioning components with different models of eyeglasses and eliminating the need for frequent changes of positioning fixtures. It can also avoid damage such as indentations and scratches on the surface of the eyeglasses during the clamping process, thus ensuring the appearance quality of the eyeglasses.

[0020] (iv) This multi-station laser welding machine for eyeglass temples integrates the drive motor and the cooling fan on the frame through the lifting frame assembly, realizing the synchronous linkage of welding operation and heat dissipation and dust reduction. The airflow generated by the cooling fan can cool the core module of the welding component, avoid equipment failure due to overheating, and can also directly act on the welding area to blow away metal fumes and prevent the weld point from oxidizing. At the same time, it reduces the risk of thermal deformation of eyeglass workpieces, and greatly improves the qualification rate and aesthetics of the welded products.

[0021] (v) The multi-station laser welding machine for eyeglass temples uses a curved pipe to receive the cold air from the air cooler, which can dissipate heat from the laser generator module inside the laser drive module and the welding head as a whole, preventing the equipment from being damaged by overheating due to continuous operation. At the same time, the curved air nozzle built into the welding head blows air directly to the weld point to cool it, which can prevent the eyeglass parts from deforming due to high temperature and avoid the oxidation of the weld point caused by high temperature, thus ensuring the precision and aesthetics of the welded product.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First embodiment, such as Figures 1 to 10 As shown, the present invention provides a technical solution: a multi-station linkage laser welding machine for eyeglass temples, comprising: a base 1, a power box 2 and a lifting frame group 4 are sequentially fixedly installed on the side of the top of the base 1, and a welding component 3 is installed on the surface of the lifting frame group 4. The lifting frame group 4 is used for adjusting the welding point and for dust reduction and heat dissipation during welding.

[0035] Positioning component 5 is fixedly installed at the middle of the top of the base 1, and the positioning component 5 is located below the lifting frame assembly 4 and the welding assembly 3.

[0036] The positioning component 5 includes a positioning seat 51. A stop strip 52 is fixedly installed at the top edge of the positioning seat 51. A positioning strip 53 is fixedly installed on the surface of the positioning seat 51 near the stop strip 52. A clamping block 56 is fixedly installed on the side of the positioning strip 53. Rotating grooves 57 are formed at both ends of the positioning strip 53. Hook-shaped parts 55 are rotatably installed on the surface of the positioning strip 53 through the rotating grooves 57. Clamping parts 54 are slidably installed on both sides of the top of the positioning strip 53. The positioning seat 51 is slidably installed on the top of the base 1. The position of the positioning seat 51 on the base 1 can be adjusted according to the size of the glasses to be welded, so that the positioning seat 51 is in the working area below the welding component 3. The glasses frame is placed on the top of the positioning seat 51. The stop strip 52 at the edge provides initial edge limitation for the glasses frame, preventing large-scale horizontal displacement of the glasses frame. After the glasses frame is attached to the stop strip 52, its edge will first overlap the clamping block 56, and the clamping block 56 provides initial support for the glasses frame.

[0037] The positioning seat 51 is slidably mounted on the top of the base 1, the clamping block 56 cooperates with the hook-shaped part 55 to support and fix the eyeglass frame, and the clamping part 54 clamps and fixes the temple of the eyeglasses.

[0038] The hook-shaped component 55 includes a rotating rod 551, with a paddle 552 sleeved on the outer surface of the rotating rod 551. A hook 554 is fixedly installed on the outer surface of the paddle 552, and a pressing groove 553 is formed inside the hook 554. When the operator moves the paddle 552 of the hook-shaped component 55, since the rotating rod 551 is rotatably installed in the rotating groove 57 of the positioning strip 53, and the paddle 552 is fixedly connected to the rotating rod 551, the paddle 552 will drive the rotating rod 551 to rotate synchronously, thereby causing the hook 554 to flip towards the eyeglass frame. After the hook 554 is engaged with the corresponding part of the eyeglass frame, its internal pressing groove 553 will fit against the surface of the eyeglass frame. At the same time, since the paddle 552 is frictionally adapted to the positioning strip 53 through the rotating rod 551, the hook-shaped component 55 will maintain the current engagement angle, and together with the clamping block 56, it will complete the firm fixation of the eyeglass frame. Moreover, the flexible plastic material of the paddle 552 and the hook 554 can avoid damaging the surface of the eyeglass frame. The three-layer frame fixing structure, consisting of a stop bar 52 for initial positioning, a clamping block 56 for support, and a hook-shaped part 55 for fastening, along with a temple clamping structure, achieves precise layered fixing of the frame and temples. This effectively prevents workpiece displacement during welding, ensures the accuracy of welding points, and improves the welding qualification rate.

[0039] The rotating rod 551 is rotatably installed inside the hook-shaped part 55. The paddle 552 and the hook 554 are both made of flexible plastic material. The paddle 552 is adapted to the positioning strip 53 through friction with the rotating rod 551.

[0040] The clamping member 54 includes a sliding plate 542. A telescopic rod 541 is fixedly installed on the outer surface of the sliding plate 542. A positioning plate 544 is fixedly installed on the outer surface of the telescopic rod 541. Baffles 543 are fixedly installed on both sides of the outer surface of the positioning plate 544. A limiting plate 545 is fixedly installed at the bottom of the baffles 543. An arc-shaped pad 547 is fixedly installed between the opposite surfaces of the limiting plates 545. An extension strip 546 is fixedly installed on the outer surface of the arc-shaped pad 547. After the frame is fixed, according to the installation position of the temples, the clamping members 54 on both sides of the top of the positioning strip 53 are slid to push the sliding plate 542 to slide on the surface of the positioning strip 53, adjusting the overall position of the clamping member 54 so that the clamping member 54 is aligned with the area to be clamped on the temples.

[0041] The sliding plate 542 is slidably mounted on top of the positioning strip 53. The baffle 543, the arc pad 547, and the extension strip 546 are all made of flexible plastic. The extension strip 546 is pressed and fitted against the limiting plate 545. After adjustment, the telescopic rod 541 extends and retracts, causing the positioning plate 544 to move downward. The baffles 543 on both sides of the positioning plate 544 first limit the temples on both sides. Then, the bottom limiting plate 545 fits against the surface of the temples. The arc pad 547 on the opposite side of the limiting plate 545 completely covers the outer surface of the temples. At the same time, the extension strip 546 on the arc pad 547 is pressed and fitted against the limiting plate 545, further enhancing the clamping tightness of the temples. Since the baffle 543, the arc pad 547, and the extension strip 546 are all made of flexible plastic, both clamping stability and scratches on the surface coating of the temples can be ensured. The lever 552 and hook 554 of the hook-shaped component 55, as well as the baffle 543, arc pad 547, and extension strip 546 of the clamping component 54, are all made of flexible plastic material, which can be adapted to eyeglass frames and temples of different sizes and curvatures, greatly improving the compatibility of the positioning component 5 with different models of eyeglasses, eliminating the need for frequent replacement of positioning fixtures; it can avoid damage such as indentations and scratches on the surface of the eyeglasses during the clamping process, ensuring the appearance quality of the eyeglasses.

[0042] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 2 to 4As shown, the lifting frame assembly 4 includes a column 41, a guide slide 42 is mounted on the outer surface of the column 41, a support rod 45 is fixedly mounted on the outer surface of the guide slide 42, a drive motor 44 is fixedly mounted on the outer surface of the support rod 45, and a cooler 43 is rotatably mounted on the bottom of the drive motor 44. When the welding assembly 3 starts laser welding, the drive motor 44 simultaneously activates the cooler 43. The low-temperature airflow generated by the cooler 43 is delivered to the laser drive module 33 through the bend 32 of the welding assembly 3. Part of the airflow cools the laser generation module, and the other part is directed towards the welding area through the bend nozzle 313, achieving rapid removal of welding fumes and real-time heat dissipation of the weld joint. If fine-tuning of the welding point is required during welding, the drive motor 44 can drive the support rod 45 to make a small horizontal displacement, and the column 41 can also drive the guide slide 42 to make slight rises and falls, ensuring the accuracy of the welding trajectory. The lifting frame assembly 4 integrates the drive motor 44 and the air cooler 43 on the support pole 45, realizing the synchronous linkage of welding operation and heat dissipation and dust reduction. The airflow generated by the air cooler 43 can cool down the core module of the welding component 3, preventing equipment failure due to overheating, and can also directly act on the welding area to blow away metal fumes and prevent the weld point from oxidizing. At the same time, it reduces the risk of thermal deformation of the eyeglass workpiece, greatly improving the qualification rate and aesthetics of the welded products.

[0043] The column 41 is fixedly installed on the side of the top of the base 1. The support rod 45 is connected to the welding assembly 3 via a transmission mechanism. The welding assembly 3 is mounted above the eyeglasses via the support rod 45. After the positioning assembly 5 completes the clamping of the eyeglasses workpiece, the power box 2 transmits a drive signal to the lifting frame assembly 4. The transmission mechanism inside the column 41 is activated, driving the guide slide 42 to slide precisely downward along the outer surface of the column 41. Simultaneously, the support rod 45 and the welding assembly 3 are lowered until the vertical distance between the welding head 31 of the welding assembly 3 and the point to be welded reaches the preset welding height. The guide slide 42 then stops moving and locks its position. After the vertical height positioning is completed, the drive motor 44 is activated. Its output end drives the support rod 45 to slide laterally along the horizontal guide rail of the guide slide 42, thereby pulling the guide seat 34 of the welding assembly 3 to move synchronously on the outer surface of the support rod 45. This achieves precise horizontal alignment of the welding head 31 until the laser emitter 311 is completely aligned with the welding joint between the eyeglass frame and the temple.

[0044] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 3 to 4As shown, the welding assembly 3 includes a laser driving module 33. A guide seat 34 is fixedly mounted on the surface of the laser driving module 33. The guide seat 34 is driven and mounted on the outer surface of the support rod 45. A bent pipe 32 is fixedly mounted on the top of the laser driving module 33 and is connected to a cooling fan 43. A welding head 31 is fixedly mounted on the bottom of the laser driving module 33. The welding assembly 3 is driven and connected to the support rod 45 of the lifting frame assembly 4 through the guide seat 34. The lifting frame assembly 4 drives the guide seat 34 to slide horizontally along the support rod 45, while simultaneously driving the laser driving module 33 to move synchronously until the welding head 31 at the bottom of the laser driving module 33 is initially aligned with the welding point of the eyeglass frame and temple. Then, the height of the guide seat 34 is adjusted by the column 41 of the lifting frame assembly 4 to achieve precise alignment between the welding head 31 and the welding point.

[0045] The welding head 31 includes a connecting seat 312, which is fixedly installed at the bottom of the laser driving module 33. A bent air nozzle 313 is fixedly installed on the inner wall of the connecting seat 312, and a laser emitting head 311 is fixedly installed inside the bent air nozzle 313. The laser driving module 33 transmits a laser signal to the welding head 31. The connecting seat 312 of the welding head 31 fixes the position of the laser emitting head 311, and the laser emitting head 311 accurately emits a laser beam to the welding point to achieve the fusion of the temple and the frame. During this process, the curved tube 32 continuously delivers cold air from the cooling fan 43 to cool the laser driving module 33 and the welding head 31 as a whole. The bent air nozzle 313 inside the welding head 31 simultaneously ejects airflow, which directly acts on the welding area, blowing away the metal fumes generated during welding, and simultaneously providing localized heat dissipation for the high-temperature weld point. The bent pipe 32 receives the cold air from the air cooler 43, which can dissipate heat from the laser generating module inside the laser drive module 33 and the welding head 31 as a whole, preventing the equipment from being damaged by overheating due to continuous operation. At the same time, the bent air nozzle 313 built into the welding head 31 blows air directly to the weld joint to cool it, which can prevent the eyeglass parts from deforming due to high temperature and avoid the oxidation of the weld joint caused by high temperature, thus ensuring the precision and aesthetics of the welded product.

[0046] In use, the positioning seat 51 is slidably mounted on top of the base 1. The position of the positioning seat 51 on the base 1 can be adjusted according to the size of the eyeglasses to be welded, so that the positioning seat 51 is located in the working area below the welding assembly 3. The eyeglass frame is placed on top of the positioning seat 51, and the edge retainer 52 provides initial edge restraint to prevent large-scale horizontal displacement of the eyeglass frame. After the eyeglass frame is aligned with the retainer 52, its edges will first overlap with the clamping block 56, which provides initial support for the eyeglass frame.

[0047] When the operator moves the lever 552 of the hook-shaped part 55, the rotating rod 551 is rotatably installed in the rotating groove 57 of the positioning strip 53, and the lever 552 is fixedly connected to the rotating rod 551. The lever 552 will drive the rotating rod 551 to rotate synchronously, thereby causing the hook 554 to flip towards the eyeglass frame. After the hook 554 is engaged with the corresponding part of the eyeglass frame, the squeezing groove 553 inside will fit against the surface of the eyeglass frame. At the same time, because the lever 552 is frictionally adapted to the positioning strip 53 through the rotating rod 551, the hook-shaped part 55 will maintain the current engagement angle, and cooperate with the clamp 56 to complete the firm fixation of the eyeglass frame. Moreover, the flexible plastic lever 552 and hook 554 can avoid damaging the surface of the eyeglass frame.

[0048] After the frame is fixed, according to the installation position of the temple, slide the clamping parts 54 on both sides of the top of the positioning strip 53, push the slide plate 542 to slide on the surface of the positioning strip 53, adjust the overall position of the clamping parts 54, and align the clamping parts 54 with the area to be clamped on the temple.

[0049] After adjustment, the telescopic rod 541 extends and retracts, causing the positioning plate 544 to move downwards. The baffles 543 on both sides of the positioning plate 544 first limit the movement of the temples on both sides. Then, the bottom limiting plate 545 fits against the surface of the temples, and the arc-shaped pad 547 on the opposite side of the limiting plate 545 completely covers the outer surface of the temples. At the same time, the extension strip 546 on the arc-shaped pad 547 will squeeze and adapt to the limiting plate 545, further enhancing the clamping tightness of the temples. Since the baffles 543, the arc-shaped pad 547, and the extension strip 546 are all made of flexible plastic, they can ensure clamping stability and avoid scratching the surface coating of the temples.

[0050] After the positioning component 5 completes the clamping of the eyeglasses workpiece, the power box 2 transmits a drive signal to the lifting frame assembly 4. The transmission mechanism inside the column 41 is activated, driving the guide slide 42 to slide precisely downwards along the outer surface of the column 41. Simultaneously, it drives the frame rod 45 and welding component 3 to descend until the vertical distance between the welding head 31 of the welding component 3 and the point to be welded reaches the preset welding height. The guide slide 42 then stops moving and locks its position. After the vertical height positioning is completed, the drive motor 44 is activated. Its output end drives the frame rod 45 to slide laterally along the horizontal guide rail of the guide slide 42, thereby pulling the guide seat 34 of the welding component 3 to move synchronously on the outer surface of the frame rod 45, achieving precise horizontal alignment of the welding head 31, until the laser emitter 311 is completely aligned with the welding joint between the eyeglass frame and the temple.

[0051] Simultaneously with the initiation of laser welding by welding assembly 3, drive motor 44 activates air cooler 43. The low-temperature airflow generated by air cooler 43 is delivered to the laser drive module 33 through the bend 32 of welding assembly 3. Part of the airflow cools the laser generation module, while the other part is directed towards the welding area through bend nozzle 313, achieving rapid removal of welding fumes and real-time heat dissipation of the weld joint. If fine-tuning of the welding point is required during welding, drive motor 44 can drive the support rod 45 to make a small horizontal displacement, and column 41 can also drive guide slide 42 to make slight rises and falls, ensuring the accuracy of the welding trajectory.

[0052] The welding assembly 3 is connected to the support rod 45 of the lifting frame assembly 4 via the guide seat 34. The lifting frame assembly 4 drives the guide seat 34 to slide horizontally along the support rod 45, while simultaneously driving the laser drive module 33 to move synchronously until the welding head 31 at the bottom of the laser drive module 33 is initially aligned with the welding point of the eyeglass frame and temple. Then, the height of the guide seat 34 is adjusted by the column 41 of the lifting frame assembly 4 to achieve precise alignment between the welding head 31 and the welding point.

[0053] The laser driving module 33 transmits a laser signal to the welding head 31. The connector 312 of the welding head 31 fixes the position of the laser emitting head 311. The laser emitting head 311 accurately emits a laser beam to the welding point, achieving the fusion of the temple and the frame. During this process, the curved tube 32 continuously delivers cold air from the cooling fan 43 to cool the laser driving module 33 and the welding head 31 as a whole. The curved air nozzle 313 inside the welding head 31 simultaneously ejects airflow, directly acting on the welding area to blow away the metal fumes generated during welding, while also providing localized heat dissipation for the high-temperature weld point.
