A laser processing head for cutting

Abstract

The present invention discloses a laser processing head for cutting, including a laser processing head, a driving component, a storage and access component, and a cooling component. In the present invention, as the time for a double-sided light absorbing plate to absorb light increases, the heat generated by diffuse reflection of a laser beam in the laser processing head is absorbed into the double-sided light absorbing plate, so that the temperature in the double-sided light absorbing plate increases. When the double-sided light absorbing plate is stored, the lifting and squeezing plate rises synchronously with the lifting and moving frame, so that the lifting and squeezing plate squeezes the airbag, so that the air in the airbag is sprayed to the surface of the double-sided light absorbing plate through the jet pipe, and the surface of the double-sided light absorbing plate can be cooled. Since the surface of the double-sided light absorbing plate is arc-shaped, the double-sided light absorbing plate can emit air to the surface of the double-sided light absorbing plate when it contacts the air sent by the airbag, so that the double-sided light absorbing plate has a better cooling effect, and the cooling is more uniform, thereby increasing the service life of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of laser processing, and specifically to a laser processing head for cutting. Background Art

[0002] A laser processing head is an important component in a laser processing device. It undertakes the terminal output of the laser beam to achieve the processing effect of the workpiece. As the end part of the beam transmission system, the laser processing head can receive radiation from a laser (usually industrial laser). Whether it is a single or multiple processing heads, its main function is to direct the focused laser beam onto the workpiece for processing operations such as cutting, welding, brazing, and cladding.

[0003] When laser processing is in use, the laser beam passes through the processing head. If there is reflected or scattered light on the outside, these rays may interfere with the focusing and guiding of the laser beam, resulting in deviation of the processing position or deterioration of the processing quality. However, the existing laser processing heads cannot perform anti-interference work, and improvements are needed for this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a laser processing head for cutting to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A laser processing head for cutting includes a laser processing head, and also includes a driving component, a storage and retrieval component, and a temperature reduction component.

[0006] Among them, the driving component includes:

[0007] A fixed extension frame is fixedly connected to the bottom outside of the laser processing head, a fixed disc is fixedly connected to the top outside of the laser processing head, an electric telescopic rod is fixedly connected to the top of the fixed disc, the electric telescopic rod has a telescopic end, and the telescopic end of the electric telescopic rod is fixedly connected to a lifting connection column, and the bottom of the lifting connection column is fixedly connected to a lifting moving frame.

[0008] According to the above technical solution, the storage and retrieval component includes a first rotating block, a telescopic rod, a second rotating block, an auxiliary connection frame, a double-sided light-absorbing plate, a connecting rotating block, and an adjusting positioning frame. The first rotating block is rotatably connected to the middle inside the lifting moving frame, the telescopic rod is fixedly connected to the side of the first rotating block away from the lifting moving frame, the second rotating block is fixedly connected to the side of the telescopic rod away from the first rotating block, the auxiliary connection frame is rotatably connected to the inside of the second rotating block, the double-sided light-absorbing plate is fixedly connected to the side of the auxiliary connection frame away from the second rotating block, the connecting rotating block is fixedly connected to the top of the double-sided light-absorbing plate, and the adjusting positioning frame is fixedly connected to the outside of the bottom of the fixed extension frame.

[0009] According to the above technical solution, the temperature reduction component includes a lifting and squeezing plate, an airbag, and a spray pipe. The lifting and squeezing plate is fixedly connected to the front and back of the lifting and moving frame. The airbag is fixedly connected to the bottom of the fixed disc and is located on the front and rear sides of the lifting connection column. The spray pipe is fixedly connected to the outer side of the top of the airbag.

[0010] According to the above technical solution, the telescopic end of the electric telescopic rod penetrates through the top of the fixed disc and extends to the lower side of the fixed disc to be fixedly connected to the top of the lifting connection column.

[0011] According to the above technical solution, a moving adjustment groove for accommodating the rotation of the telescopic rod is formed in the fixed extension frame. The first rotating block, the telescopic rod, the second rotating block, and the auxiliary connection frame are all arranged inside the fixed extension frame, and the first rotating block, the telescopic rod, the second rotating block, and the auxiliary connection frame are all in the same plane.

[0012] According to the above technical solution, the connecting rotating block is rotatably connected to the middle part inside the adjustment positioning frame, and the double-sided light-absorbing plate is rotatably connected to the adjustment positioning frame through the connecting rotating block.

[0013] According to the above technical solution, the nozzle direction of the spray pipe is inclined downward, and the shape of the double-sided light-absorbing plate is arc-shaped.

[0014] According to the above technical solution, the number of the electric telescopic rods, the lifting connection columns, the lifting and moving frames, the first rotating blocks, the telescopic rods, the second rotating blocks, the auxiliary connection frames, the double-sided light-absorbing plates, the connecting rotating blocks, the adjustment positioning frames, the lifting and squeezing plates, the airbags, and the spray pipes is four. The four electric telescopic rods, the lifting connection columns, the lifting and moving frames, the first rotating blocks, the telescopic rods, the second rotating blocks, the auxiliary connection frames, the double-sided light-absorbing plates, the connecting rotating blocks, the adjustment positioning frames, the lifting and squeezing plates, the airbags, and the spray pipes are annularly distributed at the bottom of the fixed disc.

[0015] According to the above technical solution, a fixed block is fixedly connected to the outer side of the spray pipe, and the top of the fixed block is fixedly connected to the bottom of the fixed disc.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, when the laser processing head is working, in order to prevent external stray light from interfering with the processing process, the electric telescopic rod at the top of the fixed disc is controlled to work. When the electric telescopic rod works, it can push the lifting connecting column. At this time, the lifting moving frame under the lifting connecting column descends, and the rotating block inside the lifting moving frame squeezes a pair of telescopic rods. At the same time, when the telescopic rod is squeezed, the telescopic rod pushes the rotating block two, causing the rotating block two to rotate within the auxiliary connecting frame. At the same time, when the auxiliary connecting frame is stressed, it can push the double-sided light-absorbing plate. At this time, the connecting rotating block on the double-sided light-absorbing plate rotates within the adjustment positioning frame at the bottom of the fixed extension frame, causing the double-sided light-absorbing plate to unfold and move to the outside of the laser processing head, where it can absorb external stray light and at the same time absorb the diffuse reflection generated when the laser processing head is working, ensuring that the laser beam can be transmitted to the workpiece stably and accurately. By setting the double-sided light-absorbing plate, the double-sided light-absorbing plate can absorb this stray light, scattered light, and reflected light, thereby reducing their impact on the laser beam and improving the processing accuracy and consistency;

[0017] When it is necessary to retract the double-sided light-absorbing plate to avoid affecting material taking, the electric telescopic rod is controlled to work. When the electric telescopic rod works, it drives the lifting connecting column and the lifting moving frame to rise. At this time, the lifting moving frame pulls the rotating block one and the telescopic rod, causing the telescopic rod to pull the rotating block two and the auxiliary connecting frame. At this time, when the auxiliary connecting frame is pulled, it drives the double-sided light-absorbing plate, causing the connecting rotating block on the double-sided light-absorbing plate to rotate within the adjustment positioning frame. As the lifting moving frame gradually rises, the double-sided light-absorbing plate rotates and approaches the lower side of the fixed extension frame, thus completing the storage of the double-sided light-absorbing plate and avoiding occupying too much space;

[0018] As the time for the double-sided light-absorbing plate to absorb light increases, the heat generated by the diffuse reflection of the laser beam inside the laser processing head is absorbed into the double-sided light-absorbing plate, increasing the temperature inside the double-sided light-absorbing plate. When the double-sided light-absorbing plate is being stored, the lifting extrusion plate rises synchronously with the rising of the lifting moving frame, causing the top of the lifting extrusion plate to contact the airbag. When the lifting extrusion plate continues to rise, it squeezes the airbag, causing the air inside the airbag to be ejected onto the surface of the double-sided light-absorbing plate through the air injection pipe, which can cool the surface of the double-sided light-absorbing plate. Since the surface of the double-sided light-absorbing plate is arc-shaped, when the double-sided light-absorbing plate contacts the air sent out by the airbag, the air can be dissipated to the surface of the double-sided light-absorbing plate, making the cooling effect of the double-sided light-absorbing plate better and more uniform, and improving the service life of the device.

[0032] The telescopic end of the electric telescopic rod 303 passes through the top of the fixed disk 302 and extends to the lower side of the fixed disk 302 and is fixedly connected to the top of the lifting connection column 304.

[0033] A moving adjustment groove for accommodating the rotation of the telescopic rod 402 is provided in the fixed extension bracket 301.

The auxiliary connection frame 404 is rotatably connected to the inside of the second rotating block 403. The double-sided light-absorbing plate 405 is fixedly connected to the side of the auxiliary connection frame 404 away from the second rotating block 403. The connecting rotating block 406 is fixedly connected to the top of the double-sided light-absorbing plate 405. The adjustment positioning frame 407 is fixedly connected to the outer bottom of the fixed extension bracket 301.

[0035] The temperature reduction component 5 includes a lifting extrusion plate 501, an airbag 502 and an air injection pipe 503. The lifting extrusion plate 501 is fixedly connected to the front and back of the lifting moving frame 305. The airbag 502 is fixedly connected to the bottom of the fixed disk 302 and is located on the front and back sides of the lifting connection column 304. The air injection pipe 503 is fixedly connected to the outer top of the airbag 502.

[0036] The connecting rotating block 406 is rotatably connected to the middle part inside the adjustment positioning frame 407. The double-sided light-absorbing plate 405 is rotatably connected to the adjustment positioning frame 407 through the connecting rotating block 406.

[0037] The nozzle direction of the air injection pipe 503 is inclined downward. The shape of the double-sided light-absorbing plate 405 is arc-shaped.

[0038] The number of the electric telescopic rod 303, the lifting connecting column 304, the lifting moving frame 305, the first rotating block 401, the telescopic rod 402, the second rotating block 403, the auxiliary connecting frame 404, the double-sided light-absorbing plate 405, the connecting rotating block 406, the adjusting positioning frame 407, the lifting pressing plate 501, the airbag 502 and the air jet pipe 503 is four. The four electric telescopic rods 303, the lifting connecting columns 304, the lifting moving frames 305, the first rotating blocks 401, the telescopic rods 402, the second rotating blocks 403, the auxiliary connecting frames 404, the double-sided light-absorbing plates 405, the connecting rotating blocks 406, the adjusting positioning frames 407, the lifting pressing plates 501, the airbags 502 and the air jet pipes 503 are annularly distributed at the bottom of the fixed disc 302.

[0039] A fixed block is fixedly connected to the outside of the air jet pipe 503, and the top of the fixed block is fixedly connected to the bottom of the fixed disc 302.

[0040] In the present invention, when the laser processing head 1 works, in order to prevent stray light generated outside from interfering with the processing process, the electric telescopic rod 303 at the top of the fixed disc 302 is controlled to work. When the electric telescopic rod 303 works, the electric telescopic rod 303 can push the lifting connecting column 304. At this time, the lifting moving frame 305 below the lifting connecting column 304 descends, and the first rotating block 401 inside the lifting moving frame 305 squeezes the telescopic rod 402. At the same time, when the telescopic rod 402 is squeezed, the telescopic rod 402 pushes the second rotating block 403, so that the second rotating block 403 rotates in the auxiliary connecting frame 404. At the same time, when the auxiliary connecting frame 404 is stressed, it can push the double-sided light-absorbing plate 405. At this time, the connecting rotating block 406 on the double-sided light-absorbing plate 405 rotates in the adjusting positioning frame 407 at the bottom of the fixed extension frame 301, so that the double-sided light-absorbing plate 405 unfolds and moves to the outside of the laser processing head 1, and can absorb the stray light from the outside. At the same time, it absorbs the diffuse reflection generated when the laser processing head 1 works, ensuring that the laser beam can be stably and accurately transmitted to the workpiece. By setting the double-sided light-absorbing plate 405, the double-sided light-absorbing plate 405 can absorb these stray light, scattered light and reflected light, thereby reducing their influence on the laser beam and improving the processing accuracy and consistency.

[0041] When it is necessary to retract the double-sided light-absorbing plate 405 to avoid affecting material taking, the electric telescopic rod 303 is controlled to work. When the electric telescopic rod 303 works, it drives the lifting connection column 304 and the lifting moving frame 305 to rise. At this time, the lifting moving frame 305 pulls the rotating block one 401 and the telescopic rod 402, so that the telescopic rod 402 pulls the rotating block two 403 and the auxiliary connection frame 404. At this time, when the auxiliary connection frame 404 is pulled, it drives the double-sided light-absorbing plate 405, so that the connecting rotating block 406 on the double-sided light-absorbing plate 405 rotates in the adjusting positioning frame 407. As the lifting moving frame 305 gradually rises, the double-sided light-absorbing plate 405 rotates and approaches the lower side of the fixed extension frame 301, thus completing the storage of the double-sided light-absorbing plate 405 and avoiding occupying too much space.

[0042] As the time for the double-sided light-absorbing plate 405 to absorb light increases, the heat generated by the diffuse reflection of the laser beam in the laser processing head 1 is absorbed into the double-sided light-absorbing plate 405, increasing the temperature inside the double-sided light-absorbing plate 405. When storing the double-sided light-absorbing plate 405, the lifting extrusion plate 501 rises synchronously with the lifting moving frame 305, so that the top of the lifting extrusion plate 501 contacts the airbag 502. When the lifting extrusion plate 501 continues to rise, the lifting extrusion plate 501 squeezes the airbag 502, and the air in the airbag 502 is ejected onto the surface of the double-sided light-absorbing plate 405 through the air injection pipe 503, which can cool the surface of the double-sided light-absorbing plate 405. Since the surface of the double-sided light-absorbing plate 405 is arc-shaped, when the double-sided light-absorbing plate 405 contacts the air sent out by the airbag 502, the air can be dispersed onto the surface of the double-sided light-absorbing plate 405, making the cooling effect of the double-sided light-absorbing plate 405 better and more uniform, and improving the service life of the device.
