[0040] The present utility model provides a laser processing device.

[0041] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the laser processing device includes a frame 10, a laser, a cutting fixture 20 and a dust suction mechanism 30. The frame 10 is provided with a processing opening 10a; the laser is disposed on the frame 10 and is located above the processing opening 10a; the cutting fixture 20 is movably connected to the frame 10 and is located below the laser; the cutting fixture 20 is used to fix the workpiece to be cut; the dust suction mechanism 30 is connected to the cutting fixture 20 and is used to suck the dust generated during the laser processing of the laser; wherein, the dust suction mechanism 30 moves on the frame 10 along with the cutting fixture 20 so that the dust suction mechanism 30 can suck the dust.

[0042] Specifically, the laser is fixed on the frame 10 and is located above the processing opening 10a, the cutting fixture 20 and the dust suction mechanism 30. The connection mode of the cutting fixture 20 is a movable connection, which is convenient for adjusting the processing position and angle. The dust suction mechanism 30 is disposed on the cutting fixture 20 and is used to suck the dust generated during the laser processing of the laser. In this way, the dust suction mechanism 30 moves on the frame 10 along with the cutting fixture 20. This moving mode enables the dust suction mechanism 30 to closely follow the cutting fixture 20 to suck the dust, so that the dust suction mechanism 30 does not need to move to absorb the dust after the laser processing of the laser. The dust suction mechanism 30 sucks the dust synchronously during the laser processing of the laser, effectively sucking the dust generated during the laser processing, so that the dust is absorbed by the dust suction mechanism 30 before it falls, which not only improves the dust suction effect but also improves the dust suction efficiency.

[0043] Since the movement of the dust suction mechanism 30 is synchronized with the processing position of the cutting fixture 20, it is possible to achieve real-time and effective suction of the dust in the processing area, thereby improving the accuracy and product quality of the laser processing, reducing the processing error caused by dust interference, and improving the production efficiency.

[0044] In this embodiment, the frame 10 is welded by rectangular steel pipes and has good stability and strength. The frame 10 is provided with a processing opening 10a, and the opening size can be adjusted according to the size of the object to be processed. The laser adopts an imported high-performance laser, which has characteristics such as high power, high stability and long life. In the design of the frame 10, a dust-proof cover is added to prevent dust from overflowing and improve the working environment. This design significantly improves the cleanliness of the working environment, protects the health of the operators, and is also beneficial to protecting the internal components of the equipment, reducing the adverse effects of dust on the equipment performance, and extending the service life of the equipment.

[0045] In an embodiment, please refer to Figures 1 to 3, the cutting fixture 20 includes a fixture plate 21 and a rotary pressing member 22. The fixture plate 21 is movably connected to the frame 10. The fixture plate 21 is provided with a cutting opening, and the cutting opening is disposed opposite to the processing opening 10a; the rotary pressing member 22 is disposed on the fixture plate 21 and adjacent to the cutting opening; the rotary pressing member 22 is used to press the workpiece to be cut.

[0046] The rotary pressing member 22 includes a pressing arm and a driving mechanism; the pressing arm is fixedly connected to the fixture plate 21, and the pressing arm is provided with a pressing surface; the driving mechanism is connected to the pressing arm and is used to drive the pressing arm to rotate; the driving mechanism is a motor; the output shaft of the motor is connected to the pressing arm, and the motor drives the pressing arm to rotate.

[0047] When the workpiece to be cut is placed at the cutting opening on the fixture plate 21, the pressing arm of the rotary pressing member 22 presses the workpiece to make it stable. The operator starts the motor, which drives the pressing arm to rotate, and presses the workpiece through the pressing surface to ensure that the workpiece does not move during the cutting process. At the same time, the cutting tool performs cutting operations through the processing opening 10a. After cutting is completed, the pressing arm of the rotary pressing member 22 rotates in reverse to release the workpiece. The operator removes the cut workpiece and continues the next round of cutting operations.

[0048] The cutting fixture 20 is movably connected to the fixture plate 21 on the frame 10, enabling the fixture to be flexibly adjusted in position, greatly improving the convenience and adaptability of the cutting process. The cutting opening on the fixture plate 21 is disposed opposite to the processing opening 10a. This design enables the workpiece to be accurately aligned during the cutting process, ensuring the cutting accuracy and quality. The rotary pressing member 22 is disposed on the fixture plate 21 and adjacent to the cutting opening, and is used to press the workpiece to be cut. This design effectively solves the problem of workpiece displacement caused by vibration during the cutting process, ensuring the stability and safety of cutting.

[0049] In one embodiment, please refer to Figures 1 to 3 , the dust suction mechanism 30 includes a dust suction connecting member 31, a dust collection box 32 and a pneumatic suction fan 33. One end of the dust suction connecting member 31 is hermetically connected to the cutting opening; the dust collection box 32 is fixed to the frame 10 and is detachably connected to the other end of the dust suction connecting member 31; the pneumatic suction fan 33 is installed on the dust collection box 32 and is used to adsorb dust into the dust collection box.

[0050] The structural design of the dust suction mechanism 30 is optimized. Through the sealed connection between the dust suction connecting piece 31 and the dust collection box 32, the high efficiency and stability during the dust suction process are ensured. Since one end of the dust suction connecting piece 31 is sealed and connected to the mounting hole, the leakage phenomenon during the dust suction process is effectively avoided, and the dust suction efficiency is improved. Thus, while ensuring the cleaning effect, the energy consumption is also reduced. The cooperation of the dust collection box 32 and the air pump makes the air pressure regulation more accurate and efficient. The installation position of the pneumatic suction fan 33 is designed at the top of the dust collection box 32, which can directly and quickly change the air pressure difference between the dust suction connecting piece 31 and the dust collection box 32, and optimize the ability to adsorb dust. This design effectively solves the problem of low dust suction efficiency caused by improper air pressure regulation in the prior art. Moreover, the detachable connection design of the dust collection box 32 facilitates cleaning and maintenance. Compared with the prior art, this design greatly simplifies the cleaning process of the dust collection box 32, improves the maintenance efficiency, and extends the service life of the equipment.

[0051] One end of the dust suction connecting piece 31 is sealed and connected to the cutting opening on the equipment to ensure a tight connection and prevent air leakage. The dust collection box 32 is fixed to the frame 10 and is detachably connected to the other end of the dust suction connecting piece 31. This design facilitates the cleaning and replacement of the dust collection box 32. When the pneumatic suction fan 33 works, the air pressure between the dust suction connecting piece 31 and the dust collection box 32 is reduced, so that the external air flows through the dust suction connecting piece 31, and the dust is adsorbed into the dust collection box 32. The structures of the dust suction connecting piece 31, the dust collection box 32 and the pneumatic suction fan 33 cooperate with each other to achieve efficient dust suction.

[0052] Optionally, the structure, shape and size of the dust suction connecting piece 31 can be set according to the actual use requirements, and will not be listed one by one here.

[0053] In an embodiment, please refer to Figures 1 to 3 , the dust suction connecting piece 31 includes a dust suction cylinder and a hose. The dust suction cylinder is sealed and connected to the cutting opening; one end of the hose is communicated with the dust suction cylinder, and the other end of the hose is detachably connected to the dust collection box 32.

[0054] The dust suction cylinder is convenient for installation and improves the air circulation efficiency. The dust suction cylinder is sealed and connected to the cutting opening to ensure no air leakage. One end of the hose is communicated with the dust suction cylinder, and is made of an elastic material, which is convenient for bending and extending. The hose can deform with the movement of the laser and the dust suction cylinder, and can communicate the dust collection box 32 and the dust suction cylinder while adapting to the displacement of the dust suction cylinder, so that the connection between the dust collection box 32 and the laser is more stable. The other end of the hose is detachably connected to the dust collection box 32. The dust collection box 32 is used to collect the dust and sundries generated during the dust suction process.

[0055] After starting the pneumatic exhaust fan 33, the air flow inside the dust suction cylinder will generate negative pressure, causing the hose to adsorb the dust on the surface of the laser or the dust generated by the laser, and transmit it to the dust collection box 32. When the dust collection box 32 is full of dust, the user can remove it from the other end of the hose, pour out the dust, and then reinstall it.

[0056] Optionally, a handle is provided on the side of the dust suction cylinder for the user to hold when moving the vacuum cleaner.

[0057] Optionally, the hose adopts a double-layer design, with an elastic material on the inner layer and a wear-resistant material on the outer layer to improve the durability of the hose.

[0058] In one embodiment, please refer to Figure 1 , the dust suction cylinder is a flared dust suction cylinder.

[0059] The dust suction cylinder is a cylindrical barrel, with one end of the barrel as the inlet and the other end as the flared part; the flared part is designed as a cone, and its inner diameter gradually increases to facilitate the absorption of larger-volume dust and debris. The design of the flared dust suction cylinder enables it to have a larger absorption range and improves the dust suction efficiency; the design of the reinforcing ribs helps to improve the structural stability of the dust suction cylinder when absorbing larger-volume debris and avoid deformation.

[0060] Optionally, a reinforcing rib is provided at the connection between the barrel and the flared part to enhance the structural stability of the dust suction cylinder.

[0061] In one embodiment, please refer to Figure 3 , a buckle is provided at the other end of the hose, and the dust collection box 32 is provided with a communication hole and a card slot, and the card slot is arranged around the communication hole; the buckle is snap-connected to the card slot to enable the hose and the dust collection box 32 to be detachably connected.

[0062] The card slot is arranged around the communication hole and is used to cooperate with the buckle to realize the detachable connection between the hose and the dust collection box 32. The buckle is snap-connected to the card slot to enable the hose and the dust collection box 32 to be detachably connected. During the connection process, the technician first aligns the buckle of the hose with the card slot of the dust collection box 32, and then gently presses it to make the buckle fully embedded in the card slot, thereby realizing the stable connection between the hose and the dust collection box 32. When it is necessary to replace or clean the hose, the technician only needs to press the release button of the buckle to make the buckle disengage from the card slot, and then the connection between the hose and the dust collection box 32 can be easily disassembled.

[0063] Of course, in other embodiments, the detachable connection method between the hose and the dust collection box 32 can also be other, not limited to the above-mentioned embodiments.

[0064] In one embodiment, please refer to Figure 3, a flange is provided at one end of the dust suction cylinder away from the hose, and the flange is arranged around the edge of the dust suction cylinder; the flange is bonded to the jig plate 21; the dust suction mechanism 30 includes a sealing ring, and the sealing ring is installed between the cutting opening of the jig plate 21 and the flange.

[0065] Since a flange is provided at one end of the dust suction cylinder away from the hose, and the flange surrounds the edge of the dust suction cylinder, such a design facilitates a tight fit with the cutting opening of the jig plate 21. The flange and the cutting opening of the jig plate 21 are beneficial to improving the connection stability and reliability, effectively preventing suction loss caused by loose connection during the dust suction process, thereby improving the dust suction efficiency. The setting of the sealing ring effectively prevents dust and debris from entering the connection part between the dust suction cylinder and the jig plate 21, ensures the airtightness of the dust suction system, and further improves the dust suction effect. The bonding method between the flange and the cutting opening of the jig plate 21 not only simplifies the assembly process but also reduces the manufacturing cost. At the same time, this structural design is convenient for disassembly and maintenance, and improves the service life of the product.

[0066] In another embodiment, in order to improve the connection stability between the dust suction cylinder and the frame 10, the shape of the flange is designed as a wedge-shaped structure matching the cutting opening of the jig plate 21. When the flange is inserted into the cutting opening of the jig plate 21, the connection between the flange and the cutting opening of the jig plate 21 can be made more firm through the self-locking effect of the wedge-shaped structure.

[0067] Optionally, the material of the sealing ring is selected as a high-temperature resistant and wear-resistant rubber material to improve the sealing effect and service life. At the same time, the design of the sealing ring can form a tight seal between the cutting opening of the jig plate 21 and the flange to prevent air leakage during the dust suction process.

[0068] In one embodiment, please refer to Figure 3 , the frame 10 includes a table plate 11, a workbench support plate 12 and an intermediate plate 13.

[0069] The structure of the frame 10 includes a platen 11, a workbench support plate 12, and an intermediate plate 13. The workbench support plate 12 and the laser are both provided on the platen 11. This design effectively improves the overall stability of the equipment. Compared with the prior art, this structure is more compact, reducing unnecessary space occupation, thereby providing a larger operating space and higher work efficiency in a limited working environment. The present utility model also includes a first linear motion module 40, which is provided on the workbench support plate 12, and the intermediate plate 13 is provided on the first linear motion module 40. This design makes the structure of the frame 10 more flexible and can adapt to different processing requirements. The application of the first linear motion module 40 makes the movement of the cutting jig 20 in the horizontal direction more precise and smooth, greatly improving the processing accuracy and efficiency.

[0070] In one embodiment, please refer to Figure 1 and Figure 3 , the first linear motion module 40 includes a first slide rail, a first lead screw, and a first slider. The first slide rail is provided on the workbench support plate 12, the first lead screw is rotatably connected to the first slide rail, and the first slider is slidably connected to the first lead screw; the intermediate plate 13 is connected to the first slider so that the intermediate plate 13 is slidably connected to the workbench support plate 12.

[0071] The first slide rail is provided on the workbench support plate 12, providing a solid support foundation for the entire module. The rotation connection of the first lead screw to the first slide rail ensures the precise positioning of the module during movement. The sliding connection of the first slider to the first lead screw enables the entire module to slide smoothly and steadily during movement. This structural design effectively overcomes the problems of unstable movement and inaccurate positioning existing in the prior art, greatly improving the work efficiency. The connection method between the intermediate plate 13 and the first slider enables the intermediate plate 13 to be slidably connected to the workbench support plate 12. This technical solution not only simplifies the structure, reduces the manufacturing cost, but also makes the movement of the intermediate plate 13 more flexible, facilitating adjustment and operation.

[0072] In one embodiment, please refer to Figure 1 and Figure 3 , the laser processing equipment further includes a second linear motion module 50. The second linear motion module 50 includes a second slide rail, a second lead screw, and a second slider. The second slide rail is provided on the side of the intermediate plate 13 facing away from the first slider, the second lead screw is rotatably connected to the second slide rail, and the second slider is slidably connected to the second lead screw; the cutting jig 20 is connected to the second slider.

[0073] The addition of the second linear motion module 50 improves the motion accuracy and stability of the laser processing equipment. The second slide rail is arranged on the side of the middle plate 13 facing away from the first slider. The second lead screw is rotationally connected to the second slide rail, and the second slider is slidably connected to the second lead screw. This design enables the cutting jig 20 to achieve more precise motion control. Compared with the prior art, the present utility model has higher accuracy in motion control and can meet the requirements of high-precision laser processing. The present utility model realizes the precise positioning and fixation of the workpiece through the connection between the cutting jig 20 and the second slider. This design effectively avoids the problem of workpiece position deviation during the laser processing, improves the processing accuracy, and ensures the product quality.
