[0046] A water-guided laser cutting device includes a frame 1, on which are mounted an XY motion platform 3, a water-guided laser cutting module 2, a jet angle measurement module, a protective cover 27, and a drainage system. A working platform 11 is located in the middle of the frame 1, and a mounting surface 12 is provided on the working platform 11. The working platform 11 divides the frame 1 into two layers: an upper working area and a lower equipment area. A pneumatic control cabinet is located in the equipment area, with its opening facing outwards from the frame 1. Baffles 15 are connected around the working platform 11, and sealant is applied between the baffles 15 and the working platform 11.

[0047] In this embodiment, the positive X-axis is defined as right and the negative X-axis as left; the positive Y-axis is defined as front and the negative Y-axis as back; and the Z-axis is defined as the vertical direction, with the positive Z-axis as up and the negative Z-axis as down. A flip-up cover 16 is provided on the front of the work area, and an electrical control cabinet 4 is provided on the rear. Openings with sliding doors are provided on the left and right sides. The periphery of the frame 1 can be provided with a workpiece loading area and a workpiece unloading area to facilitate loading and unloading. The loading and unloading mechanism and the XY motion platform 3 are located within the work area. The workpiece loading area and the workpiece unloading area are positioned opposite to the XY motion platform 3. Preferably, to facilitate loading and unloading operations and avoid interference with other mechanisms, the workpiece loading area and the workpiece unloading area are respectively located on the left and right sides of the XY motion platform 3, thereby cooperating to achieve automatic loading and unloading of workpieces.

[0048] The left and right sides of the frame 1 may also be provided with outer perimeter plates 17, which include multiple outer perimeter plates 17, specifically a middle outer perimeter plate 17 and a lower outer perimeter plate 17. At least one snap plate 18 is provided on the side of the outer perimeter plate 17 facing the frame 1. The snap plate 18 has an L-shaped cross-section, with its horizontal portion above its vertical portion. The vertical portion of the snap plate 18 is parallel to and spaced apart from the outer perimeter plate 17, thus forming a downward-opening snap groove 19 between the snap plate 18 and the outer perimeter plate 17. In this embodiment, a snap-fit ​​plate 151 is provided on the top of the side baffle 15. The snap-fit ​​plate 151 also has an L-shaped cross-section, with its horizontal portion below its vertical portion and connected to the baffle 15. The vertical portion of the snap-fit ​​plate 151 is located on the side of the baffle 15 away from the interior of the frame 1 and is parallel to and spaced apart from the baffle 15. Thus, the lower buckle plate 18 on the lower enclosure 17 snaps into the snap-fit ​​plate 151. At this time, the vertical part of the snap-fit ​​plate 151 is inserted into the buckle groove 19 and is located between the vertical part of the buckle plate 18 and the lower enclosure 17. The lower buckle plate 18 on the middle enclosure 17 overlaps with the buckle plate 18 on the lower enclosure 17 near the middle enclosure 17, thereby forming a labyrinth-like waterproof structure to prevent water from splashing out when working on the workbench. Sealant is applied between the enclosures 17 and between the enclosures 17 and the baffle 15.

[0049] Sealing compound is also provided between the electrical control cabinet 4 and the baffle 15. The sliding door is located above the baffle 15 and is connected to the baffle 15. A diversion plate 161 is provided on the side of the flip cover 16 facing the work area. When the flip cover 16 is placed on the work area, the lower end of the diversion plate 161 is inclined towards the inside of the work area. The lower end of the diversion plate 161 is located on the side of the front baffle 15 that is close to the inside of the work area (the top of the baffle 15 on the front side of the work platform 11 can be inclined towards the side away from the work area).

[0050] The XY motion platform 3 is mounted on the mounting surface 12 within the work area. A water guide channel 13 is installed on the mounting surface 12, surrounding the XY motion platform 3. The side walls of the water guide channel 13 are inclined away from its centerline. A drain outlet 14 is located at the lowest point of the bottom surface of the water guide channel 13. A drainage pipe is installed in the equipment area, and the drain outlet 14 and the drainage pipe constitute a drainage system.

[0051] The XY motion platform 3 includes multiple motion mechanisms 30 and a tooling bracket. The multiple motion mechanisms 30 are arranged along the Z-axis, and the sliding blocks 32 within the multiple motion mechanisms 30 move in different directions. Among adjacent motion mechanisms 30, the upper motion mechanism 30 is connected to the lower motion mechanism 30. The tooling bracket is mounted on the uppermost motion mechanism 30. In this embodiment, two motion mechanisms 30 are provided. Depending on the actual installation space, one motion mechanism 30 drives the tooling bracket to move along the X-axis and is positioned above it, while the other motion mechanism 30 drives the workpiece to move along the Y-axis. In other embodiments, the lower motion mechanism 30 may drive the tooling bracket to move along the X-axis, and the upper motion mechanism 30 may drive the tooling bracket to move along the Y-axis.

[0052] Each motion mechanism 30 includes a base 31, a slide 32, a linear drive device 33, and a waterproof component 34. The base 31 includes a base plate 311, side plates 312, and end plates 313. The side plates 312 are connected to both sides of the base plate 311 and are perpendicular to the base plate 311. The end plates 313 are located at both ends of the base plate 311 along its length and at both ends of the side plates 312. The end plates 313 are also perpendicular to the base plate 311. The base plate 311, side plates 312, and end plates 313 together form an upward-opening box shape, constituting the base 31.

[0053] The slide 32 is connected to the base plate 311 via a linear drive device 33. The slide 32 can be equipped with mounting fixtures and process modules. The linear drive device 33 is mounted on the base plate 311 and drives the slide 32 to move along the length of the base plate 311. Specifically, the slide 32 is generally W-shaped, including a sliding section 321 and two support sections 324. The sliding section 321 is a C-shaped plate with an opening facing downwards. The sliding section 321 spans the base 31 perpendicular to its sliding direction. Specifically, the sliding section 321 includes a horizontally arranged sliding plate 322 and vertically arranged vertical plates 323 on both sides of the sliding plate 322. The sliding plate 322 is connected to the actuator and is located on the side plate 312. Two vertical plates 323 are parallel to each other and located on the side of the side plate 312 away from the bottom plate 311. Support parts 324 are L-shaped and symmetrically arranged on both sides of the sliding part 321 along the length of the bottom plate 311. The horizontal portion of the support part 324, away from its vertical portion, connects to the side of the vertical plate 323 of the sliding part 321 away from the sliding plate 322, thus forming two upward-facing notches 325 between the two support parts 324 and the sliding part 321. A slide rail 331 is also provided on the bottom plate 311, extending along its length. Multiple slide rails 331 can be provided, located on both sides of the linear drive device 33. A slider adapted to the slide rail 331 is provided at the bottom of the sliding plate 322. The slider and slide rail 331 cooperate to provide support and guidance for the movement of the slide block 32.

[0054] The waterproof component 34 includes a cover plate 341, which is connected between two end plates 313. The length of the cover plate 341 along the sliding direction of the slide block 32 is greater than the length of the slide block 32. Specifically, the cover plate 341 is configured as a C-shaped plate with the opening facing downward. The two vertical parts of the cover plate 341 are parallel to each other. The cover plate 341 covers the sliding part 321. The two vertical parts of the cover plate 341 are respectively inserted into two notches 325. The cover plate 341 covers the sliding plate 322 that is horizontally set in the sliding part 321. The lower edge of the vertical part of the cover plate 341 is located below the upper edge of the side plate 312. Thus, the cover plate 341 covers the sliding part 321 and the linear drive device 33. The cover plate 341 and the base 31 together form a mounting cavity for mounting the linear drive device 33. It should be noted that the top of the vertical part of the support 324 is higher than the horizontal baffle 15. The top of the vertical parts of the two support parts 324 can be connected to a tooling bracket. An adjusting pad is provided between the tooling bracket and the two support parts 324. An adjusting screw is provided between the tooling bracket and the adjusting pad. Multiple adjusting screws are used to adjust the level of the tooling bracket.

[0055] The waterproof component 34 also includes an air pipe 342 disposed between the two end plates 313. The air pipe 342 is disposed along the length of the base plate 311 and is located between the support portion 324 and the side baffle 15. Several air jet holes are disposed along the length of the air pipe 342, and the air jet holes are disposed downward, forming a fine air curtain between the support portion 324 and the side baffle 15 to prevent water from entering the installation cavity.

[0056] A crossbeam 10 is provided on the mounting surface 12 via a support frame 103. An adjustable mounting seat is provided on the crossbeam 10. The adjustable mounting seat includes a base plate 1011, a head mounting plate 1012, a support rod 1013, a first set screw 1014, and a second set screw 1015. The base plate 1011 is fixedly connected to the crossbeam 10. In other embodiments, the base plate 1011 can also be slidably disposed on the crossbeam 10 in a vertical or horizontal direction. The head mounting plate 1012 is connected to the base plate 1011 by screws. The first set screw 1014 is disposed on the head mounting plate 1012. Multiple first set screws 1014 are disposed along the Z-axis direction. In this embodiment, there are two first set screws 1014. The first set screw 1014 penetrates the head mounting plate 1012 and abuts against the base plate 1011.

[0057] Support rods 1013 are fixedly connected to the bottom of the base plate 1011 and the head mounting plate 1012 by screws. Two support rods 1013 are arranged along the X-axis. A support surface 1016 is provided on the part of the support rod 1013 opposite to the head mounting plate 1012. The support surface 1016 is in line contact with the head mounting plate 1012. In this embodiment, the support surface 1016 is arc-shaped. A second set screw 1015 is provided on the support rod 1013. The second set screw 1015 passes through the support rod 1013 and abuts against the bottom of the head mounting plate 1012. The second set screw 1015 is opposite to the highest point of the support surface 1016. The pitch angle of the head mounting plate 1012 can be adjusted by adjusting the first set screw 1014. The left and right swing angle of the head mounting plate 1012 can be adjusted by adjusting the second set screw 1015. After adjustment, the position of the head mounting plate 1012 and the base plate 1011 is fixed by screws, thereby realizing the verticality adjustment of the head.

[0058] The head connected to the head mounting plate 1012 via the head mounting arm 21 can be a water-guided laser cutting module 2. In other embodiments, it can also be a dispensing module, a mounting module, etc. The water-guided laser cutting module 2 is mounted above the XY motion platform 3 via the crossbeam 10. It should be noted that, taking the center of gravity of the head mounting plate 1012, the head mounting arm 21, and the water-guided laser cutting module 2 as the reference point, and a straight line passing through the reference point along the Z-axis as the baseline, the first set screw 1014 and the second set screw 1015 are symmetrically arranged on both sides of the baseline.

[0059] The headstock mounting arm 21 is used to mount the water-guided laser cutting module 2, which moves relative to the mounting base. The direction of movement can be vertical or horizontal when the pitch angle of the headstock mounting plate 1012 is 0 degrees (the mounting surface 12 on the mounting base is located in the XZ plane) or the rotation angle is 0 degrees. In this embodiment, the headstock mounting arm 21 controls the water-guided laser cutting module 2 to move along the Z-axis.
