Description

Technical Field

[0001] The invention relates to the field of laser processing, and in particular to a multifunctional laser processing composite platform. Background Art

[0002] A laser processing table is a mechanical device that processes workpieces with the help of lasers. When the laser table is in use, the laser is emitted from the laser and focused into a high-power density laser beam through the optical path system. The laser beam is irradiated on the surface of the workpiece to make the workpiece reach its melting point or boiling point. The molten or vaporized metal is blown away with high-pressure gas coaxial with the beam to achieve fine processing of the workpiece.

[0003] During the laser processing process, the laser processing platform controls the relative movement of the workpiece and the light beam, and realizes operations such as cutting and engraving on the workpiece through multi-axis adjustment. Affected by the optical path system, usually only one type of multi-axis processing area is set up on a single laser processing table, and equipped with a laser corresponding to the multi-axis processing area. In actual processing production, affected by the workpiece structure and processing method, different types of workpieces need to be adjusted using different multi-axis processing areas during laser processing. In order to meet production and R&D needs, multiple laser processing platforms with different processing areas are usually set up in the same workshop, which not only takes up a large amount of production space, but also leads to a significant increase in production costs.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Embodiment: This embodiment provides a multifunctional laser processing composite platform, see Figure 1 - Fig.13 Specifically, it includes a base 1, on which an optical path system, a four-axis processing area and a five-axis processing area are arranged, a frame 101 is fixedly installed on the top of the base 1, the optical path system includes a femtosecond laser 2 fixedly installed on the base 1, an optical path beam combining module 201 connected to the femtosecond laser 2 is fixedly installed on the frame 101, and a reflector, a beam expander and a wave plate are arranged in the optical path beam combining module 201, an optical path processing module 202 connected to the optical path beam combining module 201 is fixedly installed on the frame 101, an L-shaped optical path 203 connected to the four-axis processing area and a C-shaped optical path 204 connected to the five-axis processing area are installed on the frame 101, and a An optical path switching box 205 is provided between the optical path processing module 202, the L-shaped optical path 203 and the C-shaped optical path 204, and a laser nozzle 2051 connected to the optical path processing module 202 is arranged in the optical path switching box 205, a reflector 1 2052 arranged at the intersection of the L-shaped optical path 203 and the laser nozzle 2051, and a reflector 2 2053 arranged corresponding to the optical path switching box 205 are fixedly installed in the optical path switching box 205, an electric slide rail 1 2054 located on the same straight line as the reflector 2 2053 is fixedly installed in the optical path switching box 205, and a reflector 3 2055 arranged corresponding to the laser nozzle 2051 is fixedly installed on the moving end of the electric slide rail 1 2054.

[0047] During the use of the device, the staff can perform targeted laser processing operations in the four-axis processing area and the five-axis processing area respectively. In the four-axis processing area, metal pipes can be precisely cut, drilled and engraved according to the design graphics. In the five-axis processing area, five-axis processing can be performed, which is convenient for processing workpieces with special shapes, curved surfaces and other features. The four-axis processing area and the five-axis processing area are respectively used for two different types of laser processing operations. When working, two laser beams in the 515 / 1030 band are separated from the femtosecond laser 2. The two laser beams pass through the reflector, beam expander and wave plate in the optical path combining module 201 and then are combined into the optical path processing module 202. Subsequently, the laser beam is emitted into the optical path switching box 205 through the laser nozzle 2051. When it is necessary to supply a laser beam to the four-axis processing area, the laser nozzle 2051 and the reflector are combined. There is no obstruction between the laser nozzle 2051 and the reflector 2052, and the laser beam is directly emitted to the reflector 1 2052 through the laser nozzle 2051 in the optical path switching box 205, and enters the L-shaped optical path 203 after being reflected by the reflector 1 2052. Under the transmission of the L-shaped optical path 203, the laser beam is connected to the four-axis processing area. When the laser beam needs to be supplied to the five-axis processing area, the reflector 3 2055 is driven by the electric slide 1 2054 to move between the laser nozzle 2051 and the reflector 1 2052. In this state, the laser beam emitted from the laser nozzle 2051 is directly emitted to the reflector 3 2055, and is reflected by the reflector 3 2055, so that the laser beam is changed and emitted to the reflector 2 2053, and then is reflected by the reflector 2 2053 and enters the C-shaped optical path 204. Under the transmission of the C-shaped optical path 204, the laser beam is connected to the five-axis processing area.

[0048] By arranging an L-shaped optical path 203 and a C-shaped optical path 204 in the optical path system, and arranging the reflector three 2055 in the optical path switching box 205, the real-time position of the reflector three 2055 can be adjusted by the movement control of the moving end of the electric slide rail one 2054, and the laser beam is switched to be injected into the L-shaped optical path 203 or the C-shaped optical path 204, so that a single optical path system can supply laser beams to two different processing areas, so that the device can not only perform laser processing and production of conventional pipe-like workpieces, but also perform laser processing on workpieces with complex structures such as planes, special shapes, and 3D morphologies, so that the device is more compatible and has a wider range of applications. In actual use, two laser processing areas share one femtosecond laser 2. Under the same use scope, the price of a femtosecond laser 2 can be saved, which is beneficial to significantly reduce the cost of laser processing production and research and development of workpieces, and is convenient for widespread promotion and use.

[0049] When switching the laser beam to enter the L-shaped optical path 203 or the C-shaped optical path 204, it is only necessary to use the electric slide rail 1 2054 to control the movement of the reflector 3 2055 to change the emission direction of the laser beam, making the switching of the optical path convenient. The laser beam optical path can support one-key switching without the need for unnecessary optical path debugging actions, which can effectively improve the operational convenience of the device during actual use.

[0050] In the specific implementation process, Figure 1 and Figure 2 As shown, the four-axis processing area and the five-axis processing area are respectively arranged on the front and rear sides of the top of the base 1, the optical path system is arranged between the four-axis processing area and the five-axis processing area, the base 1 is composed of marble and a square steel frame, and a protective shell 102 is fixedly installed on the top of the base 1 to cover the optical path system, the four-axis processing area and the outside of the five-axis processing area, and the front and rear sides of the protective shell 102 are respectively slidably installed with movable doors 103 arranged corresponding to the four-axis processing area and the five-axis processing area. During the use of the device, the four-axis processing area and the five-axis processing area are respectively arranged on the front and rear sides of the top of the base 1, and The optical path system is arranged between the surrounding processing area and the five-axis processing area, so that the optical path layout of a single optical path system for supplying laser beams in two processing areas is more concise and clear, so that when a femtosecond laser 2 supplies laser beams to two different laser processing areas, it will not affect the transmission of the laser beam, and the stability of the laser beam optical path transmission can be effectively guaranteed. By installing the protective shell 102 on the top of the base 1, the optical path system, the four-axis processing area and the five-axis processing area can be protected. With the help of protective isolation, the stability and safety of the device in actual use can be effectively improved.

[0051] In the specific implementation process, Figure 3 and Figure 4As shown, the four-axis processing area includes a laser head 3, a Y-axis electric slide rail 301 arranged longitudinally is fixedly installed on the front of the frame 101, and a Z-axis electric slide rail 302 arranged vertically is fixedly installed on the moving end of the Y-axis electric slide rail 301, the laser head 3 is fixedly installed on the moving end of the Z-axis electric slide rail 302, an L-shaped optical path 203 is connected between the optical path switching box 205 and the laser head 3, a X-axis electric slide rail 303 arranged transversely is fixedly installed at the lower front of the frame 101, and a shaft seat 304 is fixedly installed on the moving end of the X-axis electric slide rail 303, an A-axis pneumatic rotary table 305 is rotatably installed in the shaft seat 304, and a pneumatic clamp 305 is fixedly installed at the axis center position in the A-axis pneumatic rotary table 305. 6. A drag platform 307 arranged below the laser head 3 is fixedly installed on the top of the base 1, a long material support device 4 extending to the outside of the protective shell 102 is fixedly installed on the top of the base 1, and the long material support device 4 is arranged on the side of the shaft seat 304 away from the drag platform 307, the long material support device 4 and the pneumatic clamp 306 are located on the same straight line, the side of the drag platform 307 away from the shaft seat 304 is connected to a material receiving box 308 fixedly installed on the top of the base 1, and a pull-out box is slidably connected in the material receiving box 308, the drag platform 307 is arranged above the pull-out box, a caliper 309 is arranged between the shaft seat 304 and the drag platform 307, and a fixture adjustment mechanism 310 for controlling and adjusting the caliper 309 is fixedly installed on the top of the base 1.

[0052] During the use of the device, when the four-axis processing area is used to perform laser processing on the metal pipe, the metal pipe to be processed enters the four-axis processing area through the guidance of the long material support device 4, and the metal pipe penetrates from the inside of the A-axis pneumatic rotating table 305, and is clamped by the pneumatic clamping claw 306 set at the axis center position of the A-axis pneumatic rotating table 305. After the X-axis electric slide rail 303 is powered on and started, the shaft seat 304 can be controlled to move horizontally to the left and right, and the loosening and clamping of the pneumatic clamping claw 306 and the clamping and loosening of the caliper 309 can be coordinated to realize the metal pipe from left to right. For the rightward conveying operation, the clamping and loosening operations of the pneumatic clamp 306 and the clamping and loosening operations of the caliper 309 are performed alternately. When the pneumatic clamp 306 clamps the metal pipe and moves to the right driven by the X-axis electric slide rail 303, the caliper 309 releases the clamping of the metal pipe. Then the caliper 309 clamps the metal pipe, and the pneumatic clamp 306 releases the clamping of the metal pipe. In this state, the X-axis electric slide rail 303 drives the shaft seat 304 to move to the left and reset. The above operations are performed alternately in an orderly manner to complete the stable conveying of the metal pipe.

[0053] When the four-axis processing area is used to process the metal pipe, the right end of the metal pipe is transported to the carriage 307 and is located below the laser head 3. The laser beam derived from the optical path system is emitted through the laser head 3 and acts on the metal pipe below to perform laser processing on the metal pipe. During the laser processing, the Y-axis electric slide 301 can control the forward and backward movement of the laser head 3 after being powered on, thereby controlling the distance between the laser head 3 and the metal pipe in the forward and backward directions. The Z-axis electric slide 302 can control the up and down movement of the laser head 3 after being powered on, thereby controlling the distance between the laser head 3 and the metal pipe in the forward and backward directions. The X-axis electric slide 303 can control the left and right movement of the metal pipe after being powered on, thereby controlling the distance between the X-axis electric slide 303 and the metal pipe in the left and right directions. The distance between the metal pipe and the laser head 3 is set to realize the basic processing of the metal pipe on the X-axis, Y-axis and Z-axis. Synchronously, when the pneumatic clamp 306 clamps the metal pipe, the A-axis pneumatic rotary table 305 can be driven to rotate to make the metal pipe rotate along its central axis to realize the processing of the metal pipe on the A-axis. Through the above-mentioned structural setting, the relative position of the metal pipe and the laser head 3 is adjusted in the four axial directions to realize flexible processing of the metal pipe, so that the surrounding processing area can perform precision cutting, drilling and engraving on the metal pipe (including materials such as stainless steel, nickel-titanium alloy and cobalt-chromium alloy) according to the design graphics, so as to meet the processing requirements of various medical devices such as interventional stents, hypotubes, stapler tubes, endoscope snake bones, spiral tubes, puncture tubes, puncture needles, etc.

[0054] Since the material receiving box 308 is directly connected to the right side of the carriage 307, the metal pipe workpieces cut off after laser processing on the carriage 307 can be directly dropped into the material receiving box 308 under subsequent pushing, and finally gathered in the pull-out box provided in the material receiving box 308, so as to automatically collect the workpieces and avoid the chaotic scattering of the processed workpieces, which can not only improve the neatness of the equipment during processing and production, but also help to ensure the stability of the workpiece quality.

[0055] One end of the L-shaped optical path 203 connected to the optical path switching box 205 is set as a retractable structure, and the end of the L-shaped optical path 203 connected to the laser head 3 is also set as a retractable structure. This makes it possible for the four-axis processing area to not affect the transmission stability of the laser beam in the L-shaped optical path 203 when the laser head 3 is adjusted forward and backward and up and down through the Y-axis electric slide rail 301 and the Z-axis electric slide rail 302.

[0056] In the specific implementation process, Figure 8 and Fig.11As shown, the L-shaped optical path 203 is fixedly connected with a visual imaging system 5 which is vertically arranged just above the laser head 3. During the use of the device, by connecting the visual imaging system 5 just above the L-shaped optical path 203, with the help of the optical path transmission channel in the L-shaped optical path 203, the processing morphology below can be accurately fitted, and then the mark of the processed workpiece can be supplemented, which can effectively improve the accuracy of the device in laser processing of the workpiece.

[0057] In the specific implementation process, Figure 5 - Figure 7 As shown, the five-axis machining area includes a laser head 6, a vertically arranged Z-axis electric slide rail 601 is fixedly installed on the back of the frame 101, the laser head 6 is fixedly installed on the moving end of the Z-axis electric slide rail 601, a horizontally arranged X-axis electric slide rail 602 is fixedly installed on the top rear of the base 1, and a longitudinally arranged Y-axis electric slide rail 3 603 is fixedly installed on the moving end of the X-axis electric slide rail 602, an axis seat 604 arranged below the laser head 6 is fixedly installed on the moving end of the Y-axis electric slide rail 3 603, and a longitudinally arranged B-axis pneumatic rotary table 605 is rotatably installed in the axis seat 604, a vertically arranged C-axis pneumatic rotary table 606 is rotatably installed in the middle position of the B-axis pneumatic rotary table 605, and a pneumatic clamp 607 is fixedly installed at the top axis center position of the C-axis pneumatic rotary table 606.

[0058] During the use of the device, when the five-axis processing area is used to perform laser processing on the workpiece, the workpiece to be processed is firmly clamped by the pneumatic clamp 607, so that the workpiece to be processed is below the laser head 6, and the laser beam derived from the optical path system is emitted through the laser head 6, acting on the workpiece below to perform laser processing on the workpiece. When the Z-axis electric slide rail 601 is powered on, the laser head 6 can be controlled to move up and down, thereby controlling the distance between the laser head 6 and the workpiece in the up and down directions. When the X-axis electric slide rail 602 is powered on, the workpiece clamped by the pneumatic clamp 607 can be controlled to move left and right, thereby controlling the distance between the laser head 6 and the workpiece in the left and right directions. When the Y-axis electric slide rail 603 is powered on, the workpiece clamped by the pneumatic clamp 607 can be controlled to move forward and backward, thereby controlling the distance between the laser head 6 and the workpiece in the front and back directions, thereby realizing basic processing on the three axes of the workpiece, namely, the X-axis, the Y-axis and the Z-axis.

[0059] A power unit for driving the B-axis pneumatic rotary table 605 to rotate is installed on the shaft seat 604. The power unit can be a servo motor. Through power drive, the workpiece clamped on the pneumatic clamp 607 can be rotated on the vertical plane along the rotation axis of the B-axis pneumatic rotary table 605 to achieve B-axis processing of the workpiece. Through the rotation of the C-axis pneumatic rotary table 606, the workpiece clamped on the pneumatic clamp 607 can be rotated on the horizontal plane along the rotation axis of the C-axis pneumatic rotary table 606 to achieve C-axis machining of the workpiece. Through the above-mentioned structural setting, the relative position of the workpiece and the laser head 2 6 can be adjusted in five axial directions, and the laser processing operation is more flexible and suitable for the research and development of the workpiece. In addition, since the B-axis pneumatic rotary table 605, the C-axis pneumatic rotary table 606 and the Z-axis electric slide rail 2 601, the X-axis electric slide rail 2 602 and the Y-axis electric slide rail 3 603 are relatively independent, the five-axis processing area can be flexibly switched between three-axis plane processing and five-axis special-shaped and curved surface processing, which improves the flexibility of the use of the five-axis processing area in the device to a certain extent.

[0060] In the specific implementation process, Figure 6 As shown, a vertically arranged electric slide rail 27 is fixedly installed on the moving end of the Z-axis electric slide rail 2601, and a connecting platform 701 is fixedly installed on the moving end of the electric slide rail 27, and an auxiliary working head 702 is installed on the connecting platform 701. During the use of the device, the auxiliary working head 702 and the connecting platform 701 are connected by a quick-release structure, and the auxiliary working head 702 can be flexibly disassembled and switched according to actual processing requirements. After adjustment, the auxiliary working head 702 can be a scanning head or a cutting head. Through the cooperation of the auxiliary working head 702 and the laser head 26, the convenience of using the five-axis processing area of ​​the device to develop workpieces can be further improved.

[0061] In the specific implementation process, Figure 1 As shown, an air duct 8 extending to the four-axis processing area and the five-axis processing area is fixedly installed in the frame 101, and a dust extraction device is fixedly installed in the base 1, and the dust extraction device is connected to the air duct 8 through a three-way pipe, and an electromagnetic valve is installed in the three-way pipe. During the use of the device, the dust extraction device installed in the base 1 is powered on and started, and the dust exhaust gas generated by laser processing in the surrounding processing areas and the five-axis processing area can be extracted by the dust extraction device under the connection of the air duct 8, so as to avoid the dust exhaust gas from being discharged outward indiscriminately during the laser processing, which can not only effectively protect the health of the staff, but also help to achieve green and environmentally friendly production. The air duct 8 extending to the four-axis processing area and the air duct 8 extending to the five-axis processing area are connected to the dust extraction device through a three-way pipe. By installing an electromagnetic valve in the three-way pipe, the conduction direction of the dust extraction device can be flexibly adjusted according to actual operation requirements, which is conducive to concentrating the airflow of sucking dust exhaust gas and ensuring the stability of dust exhaust gas extraction during laser operation.

[0062] Specifically, the working principle and operation method of the present invention are as follows:

[0063] The staff can use the four-axis processing area to carry out laser processing of metal pipes, and use the five-axis processing area to carry out laser processing of special-shaped and curved workpieces. The two laser beams separated from the femtosecond laser 2 pass through the reflector, beam expander and wave plate in the optical path combining module 201 and then combine into the optical path processing module 202. Then the laser beam passes through the laser nozzle 2051 and enters the optical path switching box 205. When the four-axis processing area is enabled, the laser beam passes through the laser nozzle 2051 in the optical path switching box 205 and directly shoots to the reflector 1 2052. After reflection, The reflection of the mirror 2052 enters the L-shaped optical path 203, and is emitted through the laser head 3 under the transmission of the L-shaped optical path 203. The metal pipe to be processed is stably transported from left to right to the carriage 307 under the left and right movement of the moving end of the X-axis electric slide rail 303, and the alternating relaxation and clamping of the pneumatic clamp 306 and the caliper 309. The laser beam emitted from the laser head 3 acts on the metal pipe at the carriage 307 to perform laser processing. In this process, the Y-axis electric slide rail 301, the Z-axis electric slide rail 302 and the X-axis electric slide rail 30 The movement of the moving end 3 can adjust the relative position of the metal pipe and the laser head 3 in the up-down, left-right, front-back directions. When the pneumatic clamp 306 clamps the metal pipe, the A-axis pneumatic rotary table 305 drives it to rotate, so as to realize the four-axis processing of the metal pipe. When the five-axis processing area is enabled, the reflector 3 2055 is driven by the electric slide rail 1 2054 to move between the laser nozzle 2051 and the reflector 1 2052. The laser beam emitted from the laser nozzle 2051 is directly emitted to the reflector 3 2055, and passes through the reflector 3 2055. After reflection, the laser beam is redirected and directed toward the second reflector 2053, and then enters the C-shaped optical path 204 after being reflected by the second reflector 2053, and is emitted through the second laser head 6 under the transmission of the C-shaped optical path 204, and acts on the workpiece to be processed firmly clamped on the second pneumatic clamp 607, and performs laser processing on it. With the help of the movement of the moving ends of the Z-axis electric slide rail 2 601, the X-axis electric slide rail 2 602 and the Y-axis electric slide rail 3 603, as well as the rotation of the B-axis pneumatic rotary table 605 and the C-axis pneumatic rotary table 606, five-axis processing of the workpiece is realized.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
