Description

Technical Field

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

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

[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 lights may interfere with the focusing and guiding of the laser beam, causing the processing position to deviate or the processing quality to decrease. However, the existing laser processing head cannot perform anti-interference work, and improvements are needed to address this problem. Summary of the invention

[0007] According to the above technical solution, the storage and retrieval component includes a rotating block one, a telescopic rod, a rotating block two, an auxiliary connecting frame, a double-sided light absorbing plate, a connecting rotating block and an adjusting positioning frame. The rotating block one is rotatably connected to the middle part of the lifting and moving frame, the telescopic rod is fixedly connected to the side of the rotating block one away from the lifting and moving frame, the rotating block two is fixedly connected to the side of the telescopic rod away from the rotating block one, the auxiliary connecting frame is rotatably connected to the inside of the rotating block two, the double-sided light absorbing plate is fixedly connected to the side of the auxiliary connecting frame away from the rotating block two, 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 outer side of the bottom of the fixed extension frame.

[0008] According to the above technical solution, the cooling component includes a lifting and extrusion plate, an airbag and a jet pipe. The lifting and extrusion 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 at the front and rear sides of the lifting and connecting column, and the jet pipe is fixedly connected to the outside of the top of the airbag.

[0009] According to the above technical solution, the telescopic end of the electric telescopic rod passes through the top of the fixed disc and extends to the lower side of the fixed disc and is fixedly connected to the top of the lifting connecting column.

[0010] According to the above technical solution, a movable adjustment groove for accommodating the rotation of the telescopic rod is opened in the fixed extension frame, and the rotating block 1, telescopic rod, rotating block 2 and auxiliary connecting frame are all arranged on the inner side of the fixed extension frame, and the rotating block 1, telescopic rod, rotating block 2 and auxiliary connecting frame are all in the same plane.

[0011] According to the above technical solution, the connecting rotating block is rotatably connected to the middle part of the adjusting positioning frame, and the double-sided light absorbing plate is rotatably connected to the adjusting positioning frame through the connecting rotating block.

[0012] According to the above technical solution, the nozzle of the air jet pipe is tilted downward, and the double-sided light absorbing plate is in an arc shape.

[0013] According to the above technical solution, the number of the electric telescopic rod, the lifting connecting column, the lifting and moving frame, the rotating block one, the telescopic rod, the rotating block two, the auxiliary connecting frame, the double-sided light absorbing plate, the connecting rotating block, the adjusting positioning frame, the lifting and extruding plate, the air bag and the jet tube is four, and the four electric telescopic rods, the lifting connecting column, the lifting and moving frame, the rotating block one, the telescopic rod, the rotating block two, the auxiliary connecting frame, the double-sided light absorbing plate, the connecting rotating block, the adjusting positioning frame, the lifting and extruding plate, the air bag and the jet tube are distributed in a ring at the bottom of the fixed disc.

[0014] According to the above technical solution, a fixing block is fixedly connected to the outer side of the air jet pipe, and the top of the fixing block is fixedly connected to the bottom of the fixing disc.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the laser processing head is working, in order to prevent the external stray light from interfering with the processing process, the electric telescopic rod on the top of the fixed disc is controlled to work. When the electric telescopic rod is working, the electric telescopic rod can push the lifting connection column. At this time, the lifting and moving frame on the lower side of the lifting and moving frame descends, and the rotating block one inside the lifting and moving frame squeezes the telescopic rod. At the same time, when the telescopic rod is squeezed, the telescopic rod pushes the rotating block two, so that the rotating block two rotates in the auxiliary connecting frame. At the same time, when the auxiliary connecting frame is subjected to force, the double-sided light absorbing plate can be pushed. At this time, the connecting rotating block on the double-sided light absorbing plate rotates in the adjusting and positioning frame at the bottom of the fixed extension frame, so that the double-sided light absorbing plate is unfolded and moved to the outside of the laser processing head, so that the external stray light can be absorbed, and the diffuse reflection generated when the laser processing head is working can be absorbed, so as to ensure that the laser beam can be stably and accurately transmitted to the workpiece. By setting the double-sided light absorbing plate, the double-sided light absorbing plate 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. When the double-sided light-absorbing plate needs to be put away to avoid affecting the material taking, the electric telescopic rod is controlled to work, and the lifting connection column and the lifting movable frame are driven to rise when the electric telescopic rod is working. At this time, the lifting movable frame pulls the rotating block 1 and the telescopic rod, so that the telescopic rod pulls the rotating block 2 and the auxiliary connecting frame. At this time, the auxiliary connecting frame drives the double-sided light-absorbing plate when being pulled, so that the connecting rotating block on the double-sided light-absorbing plate rotates in the adjustment and positioning frame. As the lifting movable frame gradually rises, the double-sided light-absorbing plate rotates and approaches the lower side of the fixed extension frame, thereby completing the storage of the double-sided light-absorbing plate to avoid occupying too much space. As the double-sided light-absorbing plate absorbs light for a longer time, the heat generated by the diffuse reflection of the laser beam in the laser processing head is absorbed into the double-sided light-absorbing plate, thereby increasing the temperature inside the double-sided light-absorbing plate. 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 top of the lifting and squeezing plate contacts the airbag. When the lifting and squeezing plate continues to rise, 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, thereby cooling the surface of the double-sided light-absorbing plate. 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, thereby achieving a better cooling effect for the double-sided light-absorbing plate and a more uniform cooling, thereby increasing the service life of the device.

The rotating block 1 401 is rotatably connected to the middle part of the lifting and moving frame 305, the telescopic rod 402 is fixedly connected to the side of the rotating block 1 401 away from the lifting and moving frame 305, the rotating block 2 403 is fixedly connected to the side of the telescopic rod 402 away from the rotating block 1 401, the auxiliary connecting frame 404 is rotatably connected to the inside of the rotating block 2 403, the double-sided light absorbing plate 405 is fixedly connected to the side of the auxiliary connecting frame 404 away from the rotating block 2 403, the connecting rotating block 406 is fixedly connected to the top of the double-sided light absorbing plate 405, and the adjusting and positioning frame 407 is fixedly connected to the outer side of the bottom of the fixed extension frame 301.

[0024] The cooling component 5 includes a lifting and extrusion plate 501, an airbag 502 and an injection pipe 503. The lifting and extrusion plate 501 is fixedly connected to the front and back of the lifting and moving frame 305. The airbag 502 is fixedly connected to the bottom of the fixed disc 302 and is located at the front and rear sides of the lifting and connecting column 304. The injection pipe 503 is fixedly connected to the outer side of the top of the airbag 502.

[0025] The connecting rotating block 406 is rotatably connected to the middle part of the adjusting positioning frame 407 , and the double-sided light absorbing plate 405 is rotatably connected to the adjusting positioning frame 407 through the connecting rotating block 406 .

[0026] The nozzle of the air jet pipe 503 is tilted downward, and the double-sided light absorbing plate 405 is in an arc shape.

[0027] There are four electric telescopic rods 303, lifting connecting columns 304, lifting and moving frames 305, rotating block 1 401, telescopic rods 402, rotating block 2 403, auxiliary connecting frames 404, double-sided light absorbing plates 405, connecting rotating blocks 406, adjusting and positioning frames 407, lifting and squeezing plates 501, air bags 502 and jet pipes 503. The four electric telescopic rods 303, lifting and connecting columns 304, lifting and moving frames 305, rotating block 1 401, telescopic rods 402, rotating block 2 403, auxiliary connecting frames 404, double-sided light absorbing plates 405, connecting rotating blocks 406, adjusting and positioning frames 407, lifting and squeezing plates 501, air bags 502 and jet pipes 503 are distributed in a ring at the bottom of the fixed disc 302.

[0028] A fixing block is fixedly connected to the outer side of the air injection pipe 503 , and the top of the fixing block is fixedly connected to the bottom of the fixing disc 302 .

[0029] In the present invention, when the laser processing head 1 is working, in order to prevent the external stray light from interfering with the processing process, the electric telescopic rod 303 on the top of the fixed disk 302 is controlled to work. When the electric telescopic rod 303 is working, the electric telescopic rod 303 can push the lifting connection column 304, and the lifting and moving frame 305 on the lower side of the lifting and moving frame 304 descends, and the rotating block 1 401 inside the lifting and 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 rotating block 2 403, so that the rotating block 2 403 rotates in the auxiliary connecting frame 404. When the connecting frame 404 is subjected to force, the double-sided light absorbing plate 405 can be pushed. 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 is unfolded and moved to the outside of the laser processing head 1, so as to absorb the external stray light and absorb the diffuse reflection generated when the laser processing head 1 is working, so as to ensure that the laser beam can be transmitted to the workpiece stably and accurately. 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.

[0030] When the double-sided light-absorbing plate 405 needs to be folded up to avoid affecting the material taking, the electric telescopic rod 303 is controlled to work, and when the electric telescopic rod 303 works, it drives the lifting connection column 304 and the lifting movable frame 305 to rise. At this time, the lifting movable frame 305 pulls the rotating block 1 401 and the telescopic rod 402, so that the telescopic rod 402 pulls the rotating block 2 403 and the auxiliary connecting frame 404. At this time, the auxiliary connecting frame 404 drives the double-sided light-absorbing plate 405 when being pulled, so that the connecting rotating block 406 on the double-sided light-absorbing plate 405 rotates in the adjusting and positioning frame 407. As the lifting movable frame 305 gradually rises, the double-sided light-absorbing plate 405 rotates and approaches the lower side of the fixed extension frame 301, thereby completing the storage of the double-sided light-absorbing plate 405 to avoid occupying too much space.

[0031] As the double-sided light absorbing plate 405 absorbs light for an increased time, the heat generated by diffuse reflection of the laser beam in the laser processing head 1 is absorbed into the double-sided light absorbing plate 405, thereby increasing the temperature inside the double-sided light absorbing plate 405. When the double-sided light absorbing plate 405 is stored, the lifting and squeezing plate 501 rises synchronously with the lifting and moving frame 305, so that the top of the lifting and squeezing plate 501 contacts the air bag 502. When the lifting and squeezing plate 501 continues to rise, the lifting and squeezing plate 501 squeezes the air bag 502, so that the air in the air bag 502 is sprayed onto the surface of the double-sided light absorbing plate 405 through the jet pipe 503, so that the surface of the double-sided light absorbing plate 405 can be cooled. Since the surface of the double-sided light absorbing plate 405 is curved, the double-sided light absorbing plate 405 can emit air to the surface of the double-sided light absorbing plate 405 when it contacts the air sent out by the air bag 502, so that the cooling effect of the double-sided light absorbing plate 405 is better and the cooling is more uniform, thereby increasing the service life of the device.
