Description

Technical Field

[0001] This invention relates to the field of sheet metal processing, specifically to an integrated laser cutting and welding equipment with switchable spot modes. Background Technology

[0002] The integrated laser cutting and welding equipment is a high-efficiency processing equipment that integrates the dual core functions of laser cutting and laser welding. It can perform material cutting and joining operations on the same machine by quickly switching process parameters. The design of switchable spot modes is designed to flexibly adapt to different processing scenarios, based on the needs of high energy density and fine spot to ensure cut accuracy during cutting, and the needs of appropriate spot size and uniform energy distribution to ensure weld quality and stability during welding. It can improve processing efficiency and product consistency without changing equipment.

[0003] However, existing integrated laser cutting and welding equipment has shortcomings. If dust or impurities adhere to the surface of the plate to be welded before welding, it can easily lead to defects such as porosity and inclusions in the weld. However, existing equipment lacks an effective pre-treatment cleaning mechanism and relies on manual cleaning, which is not only inefficient but may also affect the welding effect due to incomplete cleaning. In the plate fixing process, existing fixing mechanisms mostly adopt rigid pressing, which can easily cause plate deformation due to improper pressure control. In addition, there is a lack of multi-directional stable clamping structure, which poses a high risk of plate displacement during processing. The handling of processed workpieces also mostly relies on manual prying, which is inconvenient and can easily damage the workpiece.

[0004] Therefore, this invention proposes an integrated laser cutting and welding device with switchable spot modes to address the shortcomings of existing technologies. Summary of the Invention

[0016] This invention provides an integrated laser cutting and welding device with switchable spot modes. It has the following advantages: 1. This invention, by setting up a cleaning and purification component, can drive two brush rollers to rotate in opposite directions and move laterally before welding, sweeping dust and impurities at the welding points of the two plates towards the center, and then sucking them into the filter box for collection by a fan and suction head. At the same time, during laser cutting and welding, it can adsorb the generated fumes and filter harmful particles through an activated carbon filter.

[0017] 2. This invention incorporates a buffer assembly, including a buffer spring, a slider, and a pressure switch, within the pressing component. When the second cylinder moves the pressure plate downward to fix the plate, the pressure plate can move upward to stretch the buffer spring after contacting the plate, thus achieving pressure buffering and preventing excessive instantaneous pressure. Furthermore, when the slider continues to move upward and the pressure exceeds a set threshold, the pressure switch can immediately shut off the cylinder. This solves the problems of deformation and damage caused by improper pressure control and the lack of pressure protection mechanisms in the prior art when fixing plates. It provides flexible clamping of the plate, effectively prevents plate deformation, and improves the operational safety of the equipment through pressure overload protection.

This invention, by setting up a clamping and ejecting structure, can be driven by a second motor to drive gear and rack transmission, causing the clamping blocks on both sides to move towards each other to achieve horizontal clamping and limiting of the plate, thereby improving processing stability. Furthermore, when the clamping blocks separate after processing, the structure at the end of the outer slide rail can drive the push rod to move upward and lift the plate, solving the problems of insufficient stability of the plate by only vertically fixing it in the prior art and the inconvenience of the plate being attached to the machine tool for unloading after processing. The plate is clamped in multiple directions to ensure cutting and welding accuracy, and the automatic ejection facilitates the picking and placing of workpieces, improving the overall ease of operation.

The X, Y, and Z three-axis modules can drive the laser head 5 to move flexibly, realizing the cutting and welding of metal plates, and the laser head 5 can adjust its own spot pattern according to the working status. Two pressing components are respectively set on the surface of machine tool 1 and X-axis module 3 to fix the metal sheet placed on machine tool 1 from the vertical direction, so as to prevent the sheet from shifting during laser cutting and welding and to ensure processing accuracy. The cleaning and purification component, located at the bottom of the Z-axis module 4, is used to clean dust and impurities from the plate to be welded before welding, and at the same time adsorbs harmful fumes generated during the cutting and welding process, which not only ensures the quality of the weld but also improves the working environment. The cleaning and purification component includes two first cylinders 6 and a filter box 17. A lifting frame 7 is fixedly connected to the bottom of the two first cylinders 6. Driven by the first cylinders 6, the lifting frame 7 moves the lower structure up and down, allowing the brush roller 9 to contact or separate from the surface of the board. Connecting seats 8 are fixedly connected to both sides of the bottom of the lifting frame 7, providing support for the rotational installation of the brush roller 9. The inner walls of both connecting seats 8 are rotatably connected to the brush roller 9 via bearings. The brush roller 9 can clean impurities from the surface of the board by rotating.

The output end of the first motor 10 is fixedly connected to the end of the brush roller 9. The two brush rollers 9 are connected by a transmission assembly. The transmission assembly enables the two brush rollers 9 to rotate in opposite directions, improving the impurity cleaning effect. The lifting frame 7 is fixedly connected to the rear side of the Z-axis module 4 and can move synchronously with the Z-axis module 4.

A dust filter 18 is provided inside the filter box 17 near the suction head 16. The dust filter 18 can block and collect the suction dust and impurities, preventing them from entering the subsequent structure. An activated carbon filter 19 is provided inside the filter box 17 away from the suction head 16. The activated carbon filter 19 can adsorb harmful particles in the flue gas and reduce air pollution. The clamping assembly, which is located inside the machine tool 1, is used to clamp and limit the plate material from the horizontal direction. It works with the pressing assembly to fix the plate material in multiple directions, further improving the stability during laser cutting and welding. Two ejector components are respectively located inside the machine tool 1 on both sides of the clamping component. They are used to lift the sheet metal attached to the surface of the machine tool 1 after processing, so that the operator can quickly remove the workpiece and improve the convenience of operation.

[0023] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 7Both pressing components include two second cylinders 22, which provide power for pressing down the pressure plate 27. Four second cylinders 22 are respectively located on the top of the mounting bracket 21 and the rear side of the X-axis module 3. The mounting bracket 21 is used to fix the second cylinders 22 located on the surface of the machine tool 1. Both output ends of the two second cylinders 22 are equipped with buffer components. The buffer components can alleviate the pressure of the pressure plate 27 on the plate, preventing excessive pressure from causing plate deformation. A pressure plate 27 is located on one side of each buffer component, directly contacting the plate and fixing it with its own pressure. The buffer component includes a support 23, which provides installation space and support for the internal structure of the buffer component. A buffer spring 24 is fixedly connected to the bottom end of the inner wall of the support 23. The spring 24 can absorb part of the pressure through its own elastic deformation to achieve a buffering effect. The top of the buffer spring 24 is fixedly connected to a slider 25. The slider 25 can slide within the support 23 as the pressure plate 27 moves, while simultaneously driving the buffer spring 24 to extend and retract. The top of the inner wall of the support 23 is fixedly installed with a pressure switch 26. The pressure switch 26 can detect the pressure change caused by the movement of the slider 25. When the pressure exceeds the limit, a protection mechanism is triggered. One side of the slider 25 is fixedly connected to the pressure plate 27, so that the pressure of the pressure plate 27 can be transmitted to the slider 25. The slider 25 is slidably connected to the inner wall of the support 23 to ensure the stability of the movement of the slider 25. The second cylinder 22 is electrically connected to the pressure switch 26, so that the pressure switch 26 can control the second cylinder 22 to close in time when overpressure is detected.

[0024] Please see the appendix Figure 8 and attached Figure 9The clamping assembly includes a bracket 28 and two inner slide rails 33. The bracket 28 is fixedly connected to the top of the inner wall of the machine tool 1 and is used to fix and support the second motor 29. The second motor 29 is fixedly installed at the bottom of the bracket 28 and provides power for the movement of the clamping assembly. The output end of the second motor 29 passes through the bracket 28 and is fixedly connected to a third gear 30. The third gear 30 can rotate under the drive of the second motor 29 and transmit power to the rack 32. The two inner slide rails 33 are respectively fixedly connected to the top of the inner wall of the machine tool 1 located on the bracket 28. On both sides, the inner slide rails 33 provide guidance and support for the sliding of the outer slide rails 31, ensuring the stability of the outer slide rails 31's movement direction. The outer slide rails 31 are slidably connected to the surfaces of both inner slide rails 33, allowing the outer slide rails 31 to slide on the inner slide rails 33, thereby driving the clamping blocks 39 to move. A rack 32 is provided on one side of the outer slide rails 31, meshing with a third gear 30. Through the meshing transmission between the gear and the rack 32, the rotational motion of the third gear 30 is converted into the linear motion of the outer slide rails 31. A support rod 43 is fixedly connected to the top of the outer slide rails 31, and the support rod 43 is used to connect the outer slide rails 31... 1 and clamping block 39, the movement of the outer slide rail 31 is transmitted to the clamping block 39, the top of the support rod 43 is fixedly connected to the clamping block 39, the clamping block 39 directly contacts the plate, and the horizontal clamping of the plate is achieved by the closing of the two clamping blocks 39. One end of the outer slide rail 31 is fixedly connected to the pressing block 40, which can move with the outer slide rail 31. When the clamping block 39 is separated, it triggers the action of the ejector assembly. The ejector assembly includes a sliding column 34, which is fixedly connected to the top of the inner wall of the machine tool 1, providing support and guidance for the sliding of the sliding member 36. A sliding member 3 is slidably connected to one side of the surface of the sliding column 34. 6. The slide 36 can slide on the slide column 34, thereby driving the connecting rod 37 to move. A support spring 35 is sleeved on the other side of the surface of the slide column 34. The support spring 35 can be elastically reset to keep the position of the slide 36 stable under normal conditions. The bottom of the slide 36 is rotatably connected to the connecting rod 37. The connecting rod 37 can convert the sliding of the slide 36 into the vertical movement of the push rod 38 to realize power transmission. One end of the slide column 34 is rotatably connected to the push rod 38. The push rod 38 can lift the plate upward. The push rod 38 passes through the top of the machine tool 1 to ensure that the push rod 38 can extend out of the surface of the machine tool 1 and contact the plate.

[0025] Please see the appendix Figure 5The transmission assembly includes a first pulley 11 and a first gear 14. The first pulley 11 and the first gear 14 are respectively fixedly connected to one end of the two brush rollers 9 and rotate synchronously with the brush rollers 9. A second pulley 13 is rotatably connected near the top of the connecting seat 8 of the first gear 14. The second pulley 13 can receive the power of the first pulley 11 through the synchronous belt 12 and drive the second gear 15 to rotate. The synchronous belt 12 is sleeved between the second pulley 13 and the first pulley 11. The synchronous belt 12 is used to transmit the power between the first pulley 11 and the second pulley 13 to ensure that the two move synchronously. The second gear 15 is fixedly connected to the front side of the second pulley 13. The second gear 15 can rotate with the second pulley 13 and drive the other brush roller 9 to rotate by meshing with the first gear 14. The second gear 15 meshes with the first gear 14 and changes the direction of rotation through gear meshing, so that the two brush rollers 9 rotate in opposite directions.

[0026] Please see the appendix Figure 6 The bottom of both sides of the Z-axis module 4 is provided with slide bars 41. The slide bars 41 provide guidance for the sliding of the lifting frame 7, ensuring that the lifting frame 7 remains relatively stable with the Z-axis module 4 when it moves. The top of the lifting frame 7 is slidably connected to the surface of the two slide bars 41, so that the lifting frame 7 can be adjusted along the slide bars 41. The suction head 16 is fixedly connected to the bottom of the Z-axis module 4, so that the suction head 16 can move with the Z-axis module 4 and accurately aim at the position of impurities or flue gas. The input end of the fan 20 is connected to the inside of the filter box 17, ensuring that the fan 20 can effectively draw air from the filter box 17 to form a negative pressure environment.

[0027] Please see the appendix Figure 8 and attached Figure 9 One end of the support spring 35 is fixedly connected to the slide 36, and the other end of the support spring 35 is fixedly connected to the slide column 34. By fixing both ends, the support spring 35 can apply a stable elastic force to the slide 36. The top of the machine tool 1 is provided with displacement ports 42 corresponding to the two outer slide rails 31. The displacement ports 42 provide space for the movement of the support rod 43 and avoid interference between the support rod 43 and the machine tool 1. The support rod 43 is slidably connected to the inner wall of the displacement port 42 to ensure the stability of the support rod 43 when it moves.

[0028] Working principle: The laser head 5 in this device is model HLW-2000 / 2000-ABS, which is a fiber laser. It adopts a customized high-power beam combining system to guide the laser into the cladding and core of the multi-clad transmission fiber, realizing an adjustable annular spot. This allows it to be used for cutting and welding processes. During cutting, the metal sheet to be processed is placed under the pressure plate 27 in front. The X, Y, and Z three-axis modules drive the laser head 5 to move accordingly, thereby cutting the metal sheet. When welding is required, the spot mode of the laser head 5 is adjusted, and the two metal sheets are placed under the two pressure plates 27 respectively. The laser head 5 is used to weld the two sheets into a whole.

[0029] By installing a cleaning and purification component at the laser head 5, before welding the two metal plates, the first motor 10 can be started to drive one of the brush rollers 9 to move. Under the transmission of the first pulley 11, the synchronous belt 12, and the second pulley 13, the second gear 15 rotates synchronously, thereby driving the brush roller 9 connected to the first gear 14 to rotate in the opposite direction. Then, the first cylinder 6 is started to drive the operating brush roller 9 to move down until it contacts the surface of the plate, and the X-axis module 3 is started to drive the brush roller 9 to move laterally. This can sweep the dust and impurities at the welding point of the two plates to the middle, and then suck them into the filter box 17 by the fan 20 and the suction head 16. The dust and debris are blocked and collected by the dust filter screen 18, thereby keeping the welding point of the two plates clean and avoiding the adhesion of dust and impurities that affect the welding quality. During cleaning, the laser head 5 will be retracted upwards to avoid pollution. During laser cutting or welding, the fan 20 can be started to suck the fumes generated by laser cutting and welding into the filter box 17, where the activated carbon filter screen 19 adsorbs the harmful particles in the fumes, preventing them from being inhaled and harmful to health.

[0030] The laser cutting and welding integrated machine has a buffer component in its two pressing components. When the second cylinder 22 is activated to move the pressure plate 27 downward to fix the plate, the pressure plate 27 can move upward a certain distance after contacting the plate to stretch the buffer spring 24, thus avoiding excessive pressure that could cause deformation of the metal plate. When the slider 25 on the buffer spring 24 continues to move upward, the pressure switch 26 will immediately shut off the second cylinder 22 after detecting that the pressure exceeds the set threshold to protect the plate, ensuring good safety. The pressure switch 26 is model CX20AJ2TN1210.

[0031] In addition to using the pressing component to fix the plate vertically, this laser cutting and welding integrated machine also has a clamping component. The second motor 29 can be started to drive the third gear 30 to rotate. Under the support and guidance of the inner slide rail 33, the outer slide rail 31 with racks 32 on both sides can move in opposite directions. This allows the clamping blocks 39 on the two side support rods 43 to move away or closer, realizing the clamping and limiting of the plate in the horizontal direction, further improving the stability of laser cutting and welding. When the two clamping blocks 39 are moved to both sides after processing, the pressing block 40 at the end of the outer slide rail 31 will drive the sliding part 36 to slide on the surface of the sliding column 34, and then drive the push rod 38 to move upward through the connecting rod 37 to lift the plate 1 that is attached to the machine tool, making it easy to remove and improving the convenience of operation. The support spring 35 can keep the position of the push rod 38 stable in the normal state.
