Description

Technical Field

[0001] This invention relates to a laser welding apparatus, specifically a laser welding apparatus for the production of flexible copper clad laminates, belonging to the field of flexible copper clad laminate product manufacturing technology. Background Technology

[0002] Flexible copper clad laminate (FCC) is the core substrate of flexible circuit boards for electronic devices, widely used in precision electronics fields such as smartphones, wearable devices, and automotive electronics. In the FCC production process, laser welding is a crucial step in achieving precise connections between the copper foil and the substrate, or between different FCC units. However, existing laser welding equipment has several problems: the mounting rails and conveyor belts of existing equipment are mostly designed with fixed spacing, which cannot flexibly adapt to FCC boards of different widths. When switching to produce FCC boards of different sizes, the mounting rails must be disassembled and reassembled, which is not only time-consuming but also prone to causing parallelism deviations on both sides of the mounting rails due to manual adjustments, resulting in board conveying jams or offsets, indirectly leading to misalignment of the welding position. Summary of the Invention

[0003] The purpose of this invention is to provide a laser welding device for the production of flexible copper-clad laminates. This invention achieves synchronous and flexible adjustment of the spacing between the mounting rails on both sides through an adjustment mechanism, adapting to FCC boards of different widths and avoiding the inefficiency and parallelism deviations caused by disassembly and reassembly during model changes.

A lateral moving mechanism is arranged on the second mounting beam, and a third mounting seat is arranged at the moving end of the lateral moving mechanism. A vertical moving mechanism is arranged on the third mounting seat, and a laser welding gun and a camera are respectively arranged at the moving end of the vertical moving mechanism; multiple lifting mechanisms are provided on the worktable between the mounting rails; multiple side-lifting mechanisms are provided inside the mounting rails; and a blocking mechanism is provided at the front end of the worktable.

[0005] The aforementioned laser welding device for producing flexible copper-clad laminates includes an adjustment mechanism comprising a synchronous belt wrapped around a first guide rail, the synchronous belt being fixedly connected to a first slider on the same side; a connecting rod is provided between the first guide rails, the connecting rod being connected to the main shaft of the synchronous belt; and a handwheel is provided at one end of the connecting rod.

[0006] The aforementioned laser welding device for producing flexible copper-clad laminates has a locking block on the side of the first guide rail on one side. The locking block has a vertical groove, and the lower end of the vertical groove has a circular groove that cooperates with the connecting rod. The upper end of the locking block is threaded with a locking screw, which passes through the vertical groove. The outer end of the locking screw has a handle.

[0007] The aforementioned laser welding device for producing flexible copper-clad laminates includes a lifting mechanism comprising a first mounting plate disposed between two mounting rails, a first cylinder disposed on the first mounting plate, and the telescopic end of the first cylinder being upwardly positioned and connected to the lifting plate.

[0008] The aforementioned laser welding device for producing flexible copper-clad laminates includes a side-top mechanism comprising a second mounting plate disposed inside the mounting rail, a second cylinder disposed on the second mounting plate, and the telescopic end of the second cylinder being disposed upward and connected to a side-top block.

[0009] The aforementioned laser welding device for producing flexible copper-clad laminates includes a blocking mechanism comprising a third mounting plate disposed between mounting rails, the third mounting plate being located at the front end of the lifting mechanism; a third cylinder is provided on the third mounting plate, the telescopic end of the third cylinder being upwardly positioned and connected to a fourth mounting plate, and buffer blocks being symmetrically arranged at the upper end of the fourth mounting plate.

[0010] The aforementioned laser welding device for flexible copper-clad laminate production includes a vertical moving mechanism comprising a fourth cylinder mounted on a third mounting base. The telescopic end of the fourth cylinder is downwardly positioned and connected to a fifth mounting plate. A camera device is mounted on the fifth mounting plate. A second guide rail is located below the fourth cylinder, and a second slider is mounted on the second guide rail. The second slider is fixedly connected to the fifth mounting plate. A third guide rail is located on the side of the fourth cylinder on the third mounting base, and a third slider is mounted on the third guide rail. A sixth mounting plate is located outside the third slider, and a laser welding gun is mounted on the sixth mounting plate. A connecting block is provided between the sixth mounting plate and the fifth mounting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the first slider can be driven to slide along the first guide rail by an adjustment mechanism according to the width of the FCC material plate, thereby flexibly adjusting the spacing of the mounting rails on the left and right sides. This allows for the adaptation of FCC material plates of different widths without disassembling and reinstalling the mounting rails, effectively avoiding material plate conveying jams or offsets caused by fixed mounting rail spacing. After adjustment, both ends of the FCC material plate are fitted into the conveying cavity formed by the baffle and the upper surface of the conveyor belt. The baffle provides double restraint on the material plate from the side and top, ensuring that the material plate is stably conveyed along a preset path as it moves into the worktable with the conveyor belt. When the material plate moves to the welding station, the blocking mechanism at the front of the worktable precisely blocks its movement path until it comes into contact with the material plate, achieving initial precise positioning of the material plate at the welding station and laying the positional foundation for subsequent welding processes. Subsequently, multiple lifting mechanisms located between the mounting rails on the worktable are simultaneously activated, driving the material plate upwards and aligning it with the upper part of the baffle. The end face contact process completely separates the material plate from the conveyor belt, preventing the continuous operation of the conveyor belt from interfering with the welding process. Furthermore, the contact between the material plate and the baffle further restricts the vertical displacement of the material plate, significantly improving the stability of the material plate during welding. Simultaneously, multiple side-mounting mechanisms inside the mounting rail rise synchronously, providing symmetrical support from both sides of the material plate. This effectively prevents the FCC flexible material plate from tilting due to the lack of lateral constraint after lifting, ensuring the material plate remains flat. Subsequently, the vertical movement mechanism on the first mounting beam on both sides of the worktable, the horizontal movement mechanism on the second mounting beam, and the vertical movement mechanism on the third mounting base allow for flexible adjustment of the laser welding gun and camera equipment in the vertical, horizontal, and vertical directions. During operation, the camera equipment first confirms the welding area, and then the laser welding gun performs the welding. This ensures that the laser welding gun is precisely aligned with the welding area, reducing welding deviation and guaranteeing the welding quality and pass rate of the FCC material plate.

[0012] 2. In this invention, when adjusting the spacing between the mounting rails, only the handwheel at one end of the connecting rod needs to be rotated to drive the connecting rod to rotate. The rotation of the connecting rod synchronously drives the synchronous belt in the first guide rail to rotate. The synchronous belt then drives the first slider, which is fixedly connected to it, to slide smoothly along the first guide rail. Because the synchronous belt drive has the characteristics of smooth transmission and good synchronization, it can ensure that the mounting rails on both sides always maintain precise parallelism during the spacing adjustment process, effectively avoiding the parallelism deviation problem that is easy to occur when manually disassembling and adjusting the mounting rails, and preventing jamming or offset during subsequent FCC material plate conveying. After the adjustment is completed, the locking screw at the upper end of the locking block is rotated. The locking screw laterally presses the vertical groove so that its two ends are close to each other, thereby making the circular groove at the lower end of the vertical groove tightly abut against the connecting rod. The frictional force between the circular groove and the connecting rod restricts the rotation of the connecting rod, realizing a stable lock after the mounting rail spacing is adjusted. This prevents the connecting rod from rotating on its own and the mounting rail spacing from offset due to equipment vibration during production, ensuring the positional stability of the subsequent FCC material plate conveying and laser welding, and laying the foundation for improving welding accuracy.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example: A laser welding apparatus for flexible copper clad laminate production, configured as follows Figure 1-9 As shown, it includes workbench 1, such as Figures 1 to 3As shown, the workbench 1 is made of Q235 steel plate, and the surface is treated with shot blasting and electrostatic spraying. It is used to support all components of the device and provides a stable and flat operating base for the overall welding operation. The workbench 1 is symmetrically equipped with first guide rails 2, such as... Figures 4 to 6 As shown, mounting rails 3 are symmetrically arranged on the left and right sides above the first guide rail 2. The mounting rails 3 are made of Q235 angle steel and are used to install the conveyor belt 4 and the baffle 8 to support the material plate conveying structure. The outer side of the mounting rail 3 is surrounded by the conveyor belt 4, which is made of polyurethane and is used to convey FCC material plates, realizing automated material plate feeding and replacing manual handling. A first mounting seat 5 is provided below one side of the mounting rail 3. The first mounting seat 5 is made of Q235 steel plate and is fixedly connected to the first guide rail 2 by bolts to fix the mounting rail 3 on one side and ensure the stability of the mounting rail 3 on that side. A second mounting seat 6 is provided below the mounting rail 3 on the other side. The second mounting seat 6 is also made of Q235 steel plate. The conveyor belt 4 is equipped with a first slider 7, which is slidably connected to the first guide rail 2. This slider 7 drives the other side mounting rail 3 to move, and works in conjunction with the adjustment mechanism 10 to adjust the spacing between the mounting rails 3. The outer side of the mounting rail 3 is provided with an inverted L-shaped baffle 8, which is made of 6061 aluminum alloy. A conveying cavity 9 is formed between the baffle 8 and the upper surface of the conveyor belt 4. The height of the conveying cavity 9 is adapted to the thickness of the FCC material plate, used to limit the FCC material plate and provide double constraint on the material plate from the side and above, preventing the material plate from shifting during conveying. The first guide rail 2 is equipped with an adjustment mechanism 10 for adjusting the spacing between the mounting rails 3, adapting to FCC material plates of different widths. Figure 1 and Figure 2As shown, the workbench 1 has symmetrically arranged first mounting beams 11 on its left and right sides for mounting vertical moving mechanisms 12, providing support for the subsequent adjustment structure of the welding torch and camera equipment 18; the first mounting beams 11 are equipped with vertical moving mechanisms 12, which drive the second mounting beams 13 to move vertically, adapting to welding requirements at different heights; the moving end of the vertical moving mechanism 12 is symmetrically equipped with second mounting beams 13 for mounting horizontal moving mechanisms 14, bearing the horizontal adjustment structure; the second mounting beams 13 are equipped with horizontal moving mechanisms 14, which drive the third mounting base 15 to move horizontally, adjusting the horizontal position of the welding torch and camera equipment 18; both the horizontal moving mechanism 14 and the vertical moving mechanism 12 are existing mechanisms, the principle of which is to drive the ball screw to rotate through a servo motor, driving the matching nut seat and the moving end to move, while relying on the linear guide rail for guidance to ensure accurate movement; the movement of the horizontal moving mechanism 14... The worktable 1 is equipped with a third mounting base 15, which is made of Q235 steel plate and is used to install a vertical moving mechanism 16, providing a carrier for the vertical adjustment of the welding torch and the camera equipment 18. The third mounting base 15 is equipped with a vertical moving mechanism 16, which is used to drive the laser welding torch 17 and the camera equipment 18 to move in the vertical direction, and to accurately control the distance between the welding torch and the material plate. The moving end of the vertical moving mechanism 16 is equipped with the laser welding torch 17 and the camera equipment 18, respectively. The camera equipment 18 adopts a CCD camera. The worktable 1 is equipped with multiple lifting mechanisms 19 located between the mounting rails 3, which are used to lift the FCC material plate, so that the material plate is separated from the conveyor belt 4 and abuts against the baffle 8 for positioning. The inner side of the mounting rail 3 is equipped with multiple side lifting mechanisms 20, which are used to press the material plate from both sides to prevent the material plate from tilting after being lifted. The front end of the worktable 1 is equipped with a blocking mechanism 21, which is used to block the movement of the material plate and realize the initial positioning of the material plate at the welding station.According to the width of the FCC material plate, the first slider 7 can be driven to slide along the first guide rail 2 by the adjustment mechanism 10, thereby flexibly adjusting the spacing of the mounting rails 3 on the left and right sides without disassembling the mounting rails 3, greatly shortening the changeover time. After adjustment, the two ends of the FCC material plate are fitted into the conveying cavity 9 formed by the baffle 8 and the upper surface of the conveyor belt 4. The baffle 8 can form a double limit on the material plate from the side and the top, ensuring that the material plate is always stably conveyed along the preset path when it moves into the worktable 1 with the conveyor belt 4, avoiding the impact of deviation on welding. When the material plate moves to the welding station, the blocking mechanism 21 at the front end of the worktable 1 accurately blocks it on its moving path until it abuts against the material plate, realizing the initial accurate positioning of the material plate at the welding station, laying the positional foundation for subsequent welding. Then, multiple lifting mechanisms 19 located between the mounting rails 3 on the worktable 1 are activated simultaneously, driving the material plate to rise and abut against the upper end face of the baffle 8. This process not only makes the material plate move but also makes the welding process more stable. The material plate is completely separated from the conveyor belt 4, preventing the continuous operation of the conveyor belt 4 from interfering with the welding process. Furthermore, the contact between the material plate and the baffle 8 further restricts the vertical displacement of the material plate, improving welding stability. Simultaneously, multiple side-support mechanisms 20 inside the mounting rail 3 rise synchronously, providing symmetrical support from both sides of the material plate. This effectively prevents the FCC flexible material plate from tilting due to lack of lateral constraint after lifting, ensuring the material plate remains flat. Subsequently, the vertical movement mechanism 12 on the first mounting beam 11 on the left and right sides of the workbench 1, the horizontal movement mechanism 14 on the second mounting beam 13, and the vertical movement mechanism 16 on the third mounting base 15 can flexibly adjust the positions of the laser welding gun 17 and the camera equipment 18 in the vertical, horizontal, and longitudinal directions. During operation, the camera equipment 18 first confirms the welding area, and then the laser welding gun 17 performs the welding, ensuring that the laser welding gun 17 is accurately aligned with the welding area, reducing welding deviation, and guaranteeing welding quality. Figure 6 and Figure 7As shown, the adjustment mechanism 10 includes a synchronous belt 30 wrapped around the first guide rail 2. The synchronous belt 30 is made of neoprene rubber. The synchronous belt 30 is fixedly connected to the first slider 7 on the same side by bolts to transmit power and drive the first slider 7 to move synchronously. A connecting rod 31 is provided between the first guide rails 2. The connecting rod 31 is made of 45 steel. The connecting rod 31 is connected to the main shaft of the synchronous belt 30 by a coupling to transmit torque and drive the synchronous belts 30 on both sides to rotate synchronously. A handwheel 32 is provided at one end of the connecting rod 31 for the operator to apply force and conveniently drive the connecting rod 31 to rotate. A locking block 33 is provided on the side of the first guide rail 2 on one side. The locking block 33 is made of Q235 steel plate and is used to install the locking assembly to lock the connecting rod 31. The locking block 33 is provided with a vertical groove 34. The lower end of the vertical groove 34 is provided with a circular groove 35 with a diameter that matches the connecting rod 31. The circular groove 35 cooperates with the connecting rod 31 to fit the connecting rod 31 and restrict the rotation of the connecting rod 31 by contact. The upper end of the locking block 33 is provided with a locking screw 36 threaded through it. The locking screw 36 passes through the vertical groove 34 and is used to squeeze the vertical groove 34 so that the circular groove 35 clamps the connecting rod 31. The outer end of the locking screw 36 is provided with a handle 37 made of rubber to facilitate the rotation of the screw and reduce the operating force. When adjusting the spacing between the mounting rails 3, simply rotate the handwheel 32 at one end of the connecting rod 31 to drive the connecting rod 31 to rotate. The rotation of the connecting rod 31 synchronizes with the synchronous belt 30 inside the first guide rail 2, causing the synchronous belt 30 to move. The synchronous belt 30 then drives the first slider 7, which is fixedly connected to it, to slide smoothly along the first guide rail 2. Because the synchronous belt 30 has good transmission synchronization, it ensures that the mounting rails 3 on both sides remain parallel. After adjustment, rotate the locking screw 36 at the upper end of the locking block 33. The locking screw 36 laterally presses the vertical groove 34, bringing its two ends closer together. This causes the circular groove 35 at the lower end of the vertical groove 34 to tightly abut against the connecting rod 31. The frictional force between the circular groove 35 and the connecting rod 31 restricts the rotation of the connecting rod 31, achieving a stable lock after the mounting rail spacing adjustment and preventing spacing deviation due to vibration during production. Figure 4 As shown, the lifting mechanism 19 includes a first mounting plate 40 disposed between two mounting rails 3. The first mounting plate 40 is made of Q235 steel plate and is used to mount a first cylinder 41, providing stable support for the lifting assembly. The first mounting plate 40 is equipped with the first cylinder 41, which provides lifting power to drive the lifting plate 42 to rise and fall. The telescopic end of the first cylinder 41 is set upward and connected to the lifting plate 42 through a flange. The lifting plate 42 is made of 6061 aluminum alloy plate and is used to support the material plate, directly contacting and lifting the material plate. When the material plate is positioned by the blocking mechanism 21, the telescopic end of the first cylinder 41 extends, driving the lifting plate 42 to rise vertically. After the lifting plate 42 contacts the bottom of the material plate, it continues to rise, lifting the material plate until it abuts against the upper end face of the baffle 8, so that the material plate is completely separated from the conveyor belt 4, providing stable support for welding. Figure 4 and Figure 5As shown, the side-top mechanism 20 includes a second mounting plate 50 disposed inside the mounting rail 3. The second mounting plate 50 is made of Q235 steel plate and is used to mount the second cylinder 51 to provide support for the side-top assembly. The second mounting plate 50 is equipped with the second cylinder 51, which provides side-top power to drive the side-top block 52 to rise and fall. The telescopic end of the second cylinder 51 is set upward and is threadedly connected to the side-top block 52. The side-top block 52 is made of nylon and is used to press against the side of the material plate to avoid scratching the FCC flexible material plate. While the lifting mechanism 19 lifts the material plate, the telescopic end of the second cylinder 51 extends, driving the side-top block 52 to rise vertically. After the side-top block 52 contacts both sides of the material plate, it continues to apply force, pushing the material plate towards the baffle 8 until the side of the material plate is in close contact with the baffle 8, thus constraining the material plate from both sides, preventing the material plate from tilting, and ensuring flatness during welding. Figure 4 As shown, the blocking mechanism 21 includes a third mounting plate 60 disposed between the mounting rails 3. The third mounting plate 60 is made of Q235 steel plate and is used to mount the third cylinder 61 to provide support for the blocking assembly. The third mounting plate 60 is located at the front end of the lifting mechanism 19 to ensure that the material plate is blocked and is exactly above the lifting mechanism 19. The third mounting plate 60 is equipped with the third cylinder 61. The telescopic end of the third cylinder 61 is set upward and is connected to a fourth mounting plate 62 by bolts. The fourth mounting plate 62 is made of 6061 aluminum alloy plate. The upper end of the fourth mounting plate 62 is symmetrically provided with buffer blocks 63. The buffer blocks 63 are made of silicone and are used to block the material plate, absorb the impact of the material plate, and avoid damage to the material plate. As the FCC material plate moves towards the welding station along the conveyor belt 4, the telescopic end of the third cylinder 61 extends, causing the fourth mounting plate 62 and the buffer block 63 to rise vertically. This causes the buffer block 63 to protrude from the surface of the conveyor belt 4, blocking the material plate's path. When the material plate reaches the buffer block 63, it is blocked, achieving initial positioning. The silicone buffer block 63 effectively absorbs the inertial impact force of the material plate, preventing edge deformation or copper foil scratches. Figure 8 and Figure 9As shown, the vertical moving mechanism 16 includes a fourth cylinder 70 mounted on a third mounting base 15. The telescopic end of the fourth cylinder 70 is downwardly positioned and connected to a fifth mounting plate 71 via a flange. The fifth mounting plate 71 is made of 6061 aluminum alloy and is used to mount the camera device 18, supporting the camera assembly. The camera device 18 is fixed to the fifth mounting plate 71 by bolts and is used to confirm the welding position, providing a visual reference for positioning the laser welding gun 17. A second guide rail 72 is provided below the fourth cylinder 70, and a second slider 73 is provided on the second guide rail 72. The second slider 73 is fixedly connected to the fifth mounting plate 71 by bolts and is used to cooperate with the second guide rail 72. 2. Sliding ensures smooth lifting and lowering of the fifth mounting plate 71; the third mounting base 15 is provided with a third guide rail 74 located on the side of the fourth cylinder 70, and a third slider 75 is provided on the third guide rail 74. The outer side of the third slider 75 is connected to a sixth mounting plate 76 by bolts. The sixth mounting plate 76 is a 6061 aluminum alloy plate used to install the laser welding gun 17 and support the welding components; the laser welding gun 17 is fixed on the sixth mounting plate 76 by a clamp and used to perform FCC material plate welding to achieve precise connection between copper foil and substrate; a connecting block 77 is provided between the sixth mounting plate 76 and the fifth mounting plate 71 to connect the two mounting plates and ensure that they move synchronously. When it is necessary to adjust the vertical height of the laser welding gun 17 and the camera device 18, the extension end of the fourth cylinder 70 extends or retracts, driving the fifth mounting plate 71 to move vertically along the cooperation direction of the second guide rail 72 and the second slider 73. At the same time, the sixth mounting plate 76 is driven to move synchronously along the cooperation direction of the third guide rail 74 and the third slider 75 through the connecting block 77, so that the laser welding gun 17 and the camera device 18 always maintain the same vertical height, ensuring that the camera device 18 can accurately capture the welding area of ​​the laser welding gun 17 and improve the welding positioning accuracy.

[0017] Working principle: First, adjust the spacing of the mounting rails 3 according to the width of the FCC material plate to be processed: rotate the handwheel 32 at one end of the connecting rod 31 in the adjustment mechanism 10 to drive the connecting rod 31 to rotate, which in turn drives the synchronous belt 30 in the first guide rail 2 to rotate. The synchronous belt 30 drives the first slider 7 fixed to it to slide smoothly along the first guide rail 2, so that the spacing of the mounting rails 3 on both sides is adapted to the width of the material plate. After the adjustment is completed, rotate the locking screw 36 at the upper end of the locking block 33. The screw presses the vertical groove 34 laterally so that its two ends are close together. The circular groove 35 at the lower end of the vertical groove 34 tightly abuts against the connecting rod 31. The friction force restricts the rotation of the connecting rod 31, so as to achieve a stable lock of the spacing of the mounting rails 3.

[0018] Subsequently, the two ends of the FCC material plate are fitted into the outer baffle 8 of the mounting rail 3 and the upper surface of the conveyor belt 4 to form the conveying cavity 9. The operation of the conveyor belt 4 drives the material plate to move into the workbench 1. When the material plate is fed in, the telescopic end of the third cylinder 61 of the blocking mechanism 21 extends, driving the fourth mounting plate 62 and the upper buffer block 63 to rise. The buffer block 63 blocks the material plate's travel path until the material plate and the buffer block 63 come into contact, completing the initial positioning of the material plate at the welding station.

[0019] After positioning, the telescopic end of the first cylinder 41 of the lifting mechanism 19 extends, driving the lifting plate 42 to rise. The lifting plate 42 contacts the bottom of the material plate and lifts it up until the material plate abuts against the upper end face of the baffle 8, so that the material plate is completely separated from the conveyor belt 4. At the same time, the telescopic end of the second cylinder 51 of the side lifting mechanism 20 inside the mounting rail 3 extends, driving the side lifting block 52 to rise. The side lifting block 52 pushes the two sides of the material plate to move towards the baffle 8 until the side of the material plate abuts tightly against the baffle 8, preventing the material plate from tilting due to its flexible characteristics and ensuring that the material plate is flat.

[0020] Finally, adjust the positions of the laser welding gun 17 and the camera equipment 18: adjust the vertical position of the second mounting beam 13 by using the vertical moving mechanism 12 on the first mounting beam 11 on both sides of the workbench 1, and adjust the horizontal position of the third mounting seat 15 by using the horizontal moving mechanism 14 on the second mounting beam 13; extend or retract the extension end of the fourth cylinder 70 of the vertical moving mechanism 16 on the third mounting seat 15, driving the fifth mounting plate 71 to move along the second guide rail 72 and the second slider 73, and at the same time, drive the sixth mounting plate 76 to move synchronously along the third guide rail 74 and the third slider 75 through the connecting block 77, so that the laser welding gun 17 and the camera equipment 18 are adjusted to the appropriate vertical height for welding; during operation, the camera equipment 18 first confirms the welding position of the material plate, and after confirmation, the laser welding gun 17 is started and performs welding operation on the material plate, completing the laser welding process of the FCC material plate.
