Description

A laser drilling device for diamond tools Technical Field

[0001] This invention relates to the field of laser beam processing technology, and in particular to a laser drilling processing device for diamond tools. Background Technology

[0002] Laser processing of diamond tools utilizes the high energy density of lasers to cause phase transformation or removal of diamond materials, thereby achieving processing operations such as cutting, drilling, and grooving. In laser processing of diamond tools, hot and cold processing are usually combined to form a process link of roughing hot processing and finishing cold processing, taking into account both processing efficiency and final accuracy.

[0003] The processing zone of nanosecond thermal processing reaches temperatures of thousands of degrees Celsius. Carbon reacts violently with oxygen, generating large amounts of CO and CO2, which are major sources of pollutants. At the same time, laser processing of diamonds produces micron and nano-sized dust, which are easily inhaled pollutants.

[0004] To address the aforementioned issues, most existing diamond tool laser processing equipment is relatively enclosed and equipped with a dedicated ventilation system to prevent toxic gases and dust generated during the laser processing from spilling into the surrounding environment and causing pollution. However, the ventilation systems of existing processing equipment are mostly located far from the laser processing center. For deep grooving and drilling, it is difficult to promptly and quickly eliminate dust and gas pollution generated inside the deep holes, affecting the normal progress of laser processing. This also prolongs the post-laser processing waiting time and reduces the overall efficiency of laser processing. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a laser drilling processing device for diamond tools. This invention enables open processing, which not only improves the environment within the processing workshop but also significantly shortens the clamping and processing time before and after processing, thereby greatly improving the efficiency of laser processing of diamond tools.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a laser drilling processing device for diamond tools, comprising a processing platform, a clamping device for clamping diamond tools, a laser generating device, and a positioning control device for controlling the movement of the laser generating device, a rotary drive device between the positioning control device and the laser generating device, the rotary drive device comprising a rotary positioning frame, a drive shaft, and an eccentric disk fixed to the drive shaft, the laser generating device being fixed to the side wall of the eccentric disk; and an airflow cleaning device near the clamping device, the airflow cleaning device comprising an air blowing device located outside the rotation path of the laser generating device, the air blowing device blowing cleaning airflow toward the surface of the diamond tool, and a flow guiding device located on both sides of the rotation path of the laser generating device, the flow guiding device blowing flow parallel to the surface of the diamond tool.

[0007] Preferably, during the laser drilling process on the surface of the diamond tool, the cleaning airflow and the guiding airflow are blown out alternately to avoid the two airflows interfering with each other and causing dust to disperse.

[0008] Preferably, the air blowing device includes an arc-shaped first air blowing opening and a second air blowing opening, both of which are inclined toward the center. During the rotation of the laser generator, the first air blowing opening and the second air blowing opening are controlled to alternately blow out cleaning airflow.

[0009] Preferably, the flow guiding device includes a first flow guiding opening and a second flow guiding opening, the first flow guiding opening and the second flow guiding opening are connected by an airflow circulation component, and the first air blowing opening and the second air blowing opening are connected to an external air source.

[0010] Preferably, a control cam is fixed on the outside of the drive shaft, and a first control valve and a second control valve are provided on the outside of the control cam. The first control valve and the second control valve are symmetrically arranged around the control cam, and the first control valve and the second control valve are connected to the airflow circulation assembly and the external air source.

[0011] Preferably, the first control valve includes a first valve body, a first valve core, and a first valve stem, wherein the first valve core divides the interior of the first valve body into a first outer chamber and a first inner chamber; the second control valve includes a second valve body, a second valve core, and a second valve stem, wherein the second valve core divides the interior of the second valve body into a second outer chamber and a second inner chamber; the airflow circulation assembly is connected in series with the first outer chamber and the second outer chamber through a third pipe, the first air blowing opening and the first inner chamber are connected to the external air source through a first pipe, and the second air blowing opening and the second inner chamber are connected to the external air source through a second pipe.

[0012] With the above structural design, there is no need for multiple solenoid valves to coordinate control. The above actions are performed automatically during the rotation of the cam. The cleaning airflow and the guiding airflow are blown out alternately at a predetermined frequency to achieve efficient and continuous absorption of polluting gases and dust. At the same time, the control frequency of the airflow changes synchronously with the rotation speed of the laser generator. Automatic control can coordinate with the changes in the amount of polluting gas generated, which is simple and efficient.

[0013] Preferably, both the first valve stem and the second valve stem have a reset elasticity and are normally extended.

[0014] Preferably, the clamping device includes a relatively fixed clamping positioning frame, the inner wall of which is rotatably connected to a clamping body, and a rotating shaft for controlling the clamping body to rotate 180°.

[0015] Preferably, the airflow cleaning device is connected to the rotating positioning frame via a telescopic assembly, the telescopic assembly including a telescopic base and a telescopic end, and the airflow cleaning device is fixedly connected to the telescopic end.

[0016] Preferably, the clamping device is arranged vertically or at an angle, and the laser generator is located on the horizontal outer side or the lower outer side of the clamping device.

[0017] The beneficial effects of this invention are as follows: Through the above structural design, the cleaning airflow and the guiding airflow work together to blow out and collect contaminants deep inside the holes processed by the diamond tool. The cleaning and guiding are carried out quickly on the outside of the diamond tool processing area, minimizing the spillage and diffusion of contaminants. With the above structure, the requirements for the sealing and fresh air system of the laser processing device are greatly reduced, enabling open processing. This not only improves the environment inside the processing workshop but also greatly shortens the clamping and processing time before and after processing, thus greatly improving the efficiency of laser processing of diamond tools.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] To address the problems mentioned in the background art, referring to Figures 1-8, a laser drilling processing apparatus for diamond tools includes a processing platform 100. The upper end of the processing platform 100 is provided with a clamping device 500 for holding diamond tools, a laser generator 400, and a position control device 200 for controlling the movement of the laser generator 400. The clamping device 500 can clamp and position the diamond tool, ensuring the accuracy of the diamond tool's processing position and stability during the processing. The position control device 200 can drive the laser generator 400 to move to a predetermined position, ensuring the accuracy of the processing point and enabling rapid switching between multiple processing points.

[0029] Position control device 200 includes X-axis drive rail 210 and Y-axis drive rail 220, which can control the laser generator 400 to move along the X-axis or Y-axis direction to achieve fast and accurate drive positioning and meet the processing requirements of multiple machining holes on the surface of diamond tools.

[0030] A rotary drive device 300 is provided between the position control device 200 and the laser generator 400. The rotary drive device 300 can control the eccentric rotation of the laser generator 400 to perform ring-shaped cutting on the surface of the diamond tool, which is suitable for larger and deeper holes. The rotary drive device 300 includes a rotary positioning frame 310, a drive shaft 320, and an eccentric disk fixed to the drive shaft 320. The laser generator 400 is fixed to the side wall of the eccentric disk. The laser generator 400 and the eccentric disk are detachably connected, and the eccentric disk is detachably connected to the end of the drive shaft 320. The specifications of the eccentric disk can be switched according to the size of the hole to meet the processing requirements of holes of different sizes.

[0031] It also includes an airflow cleaning device 600 located near the clamping device 500. The airflow cleaning device 600 can perform targeted cleaning and centralized collection of polluting gases and dust generated by laser processing, collecting the pollutants at the source and preventing them from overflowing and spreading.

[0032] The airflow cleaning device 600 includes an air blowing device 620 located outside the rotation path of the laser generating device 400. The air blowing device 620 blows cleaning airflow toward the surface of the diamond tool. The cleaning airflow can blow out the contaminants generated inside the machining holes, achieving real-time deep cleaning. It also includes a guide device 610 located on both sides of the rotation path of the laser generating device 400. The guide device 610 blows out a guide airflow parallel to the surface of the diamond tool. The guide airflow can form an airflow barrier, which concentrates and collects the contaminants blown out by the cleaning airflow, further preventing the diffusion and overflow of contaminants.

[0033] As optional operating parameters, the cleaning airflow pressure of 0.3-0.6MPa is a dry inert protective gas used to blow away diamond dust generated during laser processing; the guiding airflow pressure of 0.1-0.2MPa flows parallel to the tool surface to form an airflow barrier, preventing dust from flowing back to the processing area. The combination of the two results in a dust removal rate of over 98%.

[0034] The clamping device 500 is preferably arranged vertically or at an angle. The laser generating device 400 is located on the horizontal outer side or the lower outer side of the clamping device 500. Through the above structural design, the holes processed on the surface of the diamond tool are horizontally oriented to the outside or horizontally oriented to the bottom. This can accelerate the settling of dust in conjunction with gravity, and prevent fine dust from remaining in the deeper parts of the holes. Combined with the cleaning airflow and the guiding airflow, deep cleaning can be achieved.

[0035] In summary, through the above structural design, the combined action of cleaning and guiding airflow can blow out and collect contaminants deep within the holes processed by diamond tools. The cleaning and guiding processes are carried out rapidly on the outside of the diamond tool processing area, minimizing the spillage and diffusion of contaminants. This structure significantly reduces the requirements for sealing and ventilation systems in the laser processing equipment, enabling open processing. This not only improves the environment within the processing workshop but also greatly shortens the clamping and processing time before and after processing, significantly increasing the efficiency of laser processing with diamond tools.

[0036] For larger diamond tools, the processing generates more contaminants. Therefore, it's necessary to increase the cleaning and guiding airflow. To avoid interference between the two airflows, during laser drilling on the diamond tool surface, the cleaning and guiding airflows are alternately blown out. The alternation cycle is adjusted according to the hole diameter: 0.5-1 seconds for drilling small holes (φ0.1-0.5mm) and 1-2 seconds for drilling larger holes (φ0.5-2mm), ensuring timely dust removal without affecting laser focusing. Alternating control can be achieved through a solenoid valve with a response time ≤0.1 seconds, ensuring precise and synchronized airflow switching and preventing interference between the two airflows that could cause dust dispersion.

[0037] Specifically, the air blowing device 620 includes an arc-shaped first air blowing opening 621 and a second air blowing opening 622. Both the first air blowing opening 621 and the second air blowing opening 622 are inclined towards the center. During the rotation of the laser generating device 400, the first air blowing opening 621 and the second air blowing opening 622 are controlled to alternately blow out cleaning airflow. There is an annular hole between the first air blowing opening 621 and the second air blowing opening 622, which will not interfere with the laser processing of the laser generating device 400.

[0038] The first air-blowing opening 621 and the second air-blowing opening 622 have an internal tilt angle of 30-45°, converging towards the center of the diamond tool processing area to ensure that the airflow accurately acts on the dust-generating area. For larger holes, this dust-generating area is annular. When the laser generator 400 rotates, when the laser beam is located in the area corresponding to the first air-blowing opening 621, the second air-blowing opening 622 blows air; when it rotates to the area corresponding to the second air-blowing opening 622, the first air-blowing opening 621 blows air, achieving follow-up cleaning and avoiding airflow obstructing the laser beam.

[0039] Specifically, the flow guiding device 610 includes a first flow guiding opening 611 and a second flow guiding opening 612. The first flow guiding opening 611 and the second flow guiding opening 612 are connected by an airflow circulation component 740. The airflow circulation component 740 can form a circulating airflow, control the first flow guiding opening 611 to blow out gas, and control the second flow guiding opening 612 to form a negative pressure to absorb gas. The flow guiding airflow circulates directionally between the first flow guiding opening 611 and the second flow guiding opening 612, realizing the centralized collection of overflowing dust.

[0040] The first air blowing opening 621 and the second air blowing opening 622 are connected to an external air source 730. The external air source 730 can spray gas toward the first air blowing opening 621 or the second air blowing opening 622 to achieve the spraying of cleaning airflow.

[0041] The first guide opening 611 and the second guide opening 612 are symmetrically arranged on both sides of the laser rotation path, preferably on the upper and lower sides. The opening direction is parallel to the tool surface, and the spacing is 50-80mm, forming a directional flow of guide air. This allows for the directional and concentrated collection of polluting gases and dust generated during laser processing. Furthermore, the guide airflow can be recycled, filtered, and reused through the airflow circulation component 740, reducing energy consumption. The external air source 730 is a high-pressure air pump that stably ejects the cleaning airflow.

[0042] Furthermore, a control cam 330 is fixed to the outside of the drive shaft 320. A first control valve 710 and a second control valve 720 are provided on the outside of the control cam 330. The first control valve 710 and the second control valve 720 are symmetrically arranged around the control cam 330. The first control valve 710 and the second control valve 720 are connected to the airflow circulation assembly 740 and the external air source 730. The directional rotation of the control cam 330 can control the conduction state of the first control valve 710 and the second control valve 720, thereby controlling the conduction state of the external air source 730 and the airflow circulation assembly 740, realizing the alternating blowing of the cleaning airflow and the guiding airflow, and also controlling the cleaning airflow to be alternately blown out from the first air blowing opening 621 and the second air blowing opening 622.

[0043] The control cam 330 is an eccentric wheel structure that rotates synchronously with the drive shaft 320. During rotation, it alternately squeezes the valve stems of the first control valve 710 and the second control valve 720, achieving automatic valve switching. The first control valve 710 controls the airflow of the first air blowing opening 621 and the first guide opening 611, while the second control valve 720 controls the airflow of the second air blowing opening 622 and the second guide opening 612. It is precisely synchronized with the rotation trajectory of the laser generator 400, requiring no additional sensor control, and has a simple and reliable structure.

[0044] Specifically, the first control valve 710 includes a first valve body 712, a first valve core 713, and a first valve stem 711. The first valve core 713 divides the interior of the first valve body 712 into a first outer chamber and a first inner chamber. The second control valve 720 includes a second valve body 722, a second valve core 723, and a second valve stem 721. The second valve core 723 divides the interior of the second valve body 722 into a second outer chamber and a second inner chamber. The chamber located closer to the control cam 330 is the inner chamber, and the chamber located farther from the control cam 330 is the outer chamber.

[0045] The airflow circulation assembly 740 is connected in series with the first outer chamber and the second outer chamber through the third pipe 741. With the above design, the third pipe 741 is only in a conductive state when both outer chambers are conductive, and only then can the flow of air be controlled. The first air blowing opening 621, the first inner chamber and the external air source 730 are connected through the first pipe 731, and the second air blowing opening 622, the second inner chamber and the external air source 730 are connected through the second pipe 732. At this time, when any one inner chamber is conductive, the cleaning airflow generated by the external air source 730 can pass through any one inner chamber and finally blow out from the first air blowing opening 621 or the second air blowing opening 622.

[0046] The valve body is made of brass, and the valve core has a rubber sealing structure to ensure airflow sealing. Rollers can be installed at the ends of the first valve stem 711 and the second valve stem 721 to roll against the surface of the control cam 330, reducing wear. The first pipe 731 and the second pipe 732 are made of PU hoses, which are resistant to high pressure and have good flexibility. When the control cam 330 squeezes the first valve stem 711, the first valve core 713 moves outward (at this time, the outer chamber is compressed and the inner chamber increases). The first inner chamber is connected to the external air source 730, and the first air blowing opening 621 blows air. At the same time, the first outer chamber and the airflow circulation assembly 740 are closed to prevent the first guide opening 611 from blowing air, thus avoiding mutual interference between airflows and achieving synchronous control.

[0047] Both the first valve stem 711 and the second valve stem 721 have a reset elasticity and are normally extended. A first reset elastic element 714 is provided between the first valve core 713 and the first valve body 712, and a second reset elastic element 724 is provided between the second valve core 723 and the second valve body 722. The first reset elastic element 714 and the second reset elastic element 724 can control the corresponding valve stem to be normally extended, and can cooperate with the outer control cam 330 to achieve accurate control of the extension and retraction of the valve stem.

[0048] It should be noted that the first reset elastic element 714 and the second reset elastic element 724 mentioned above have large reset elasticity, which can compress the gas in the valve body or squeeze it into the elastic structure of the outer hose, so as to ensure the normal reset of the first valve core 713 and the first valve stem 711.

[0049] In summary, through the cooperation of the first control valve 710, the second control valve 720, and the control cam 330, the airflow circulation assembly 740 and the external air source 730 are connected in series and in parallel with the outer chambers, respectively. When the control cam 330 rotates to the side of the first control valve 710 and the second control valve 720 at the protruding position, the corresponding inner chamber can be controlled to be in a conducting state, thereby controlling the first air blowing opening 621 and the second air blowing opening 622 to spray out cleaning airflow. At the same time, the connected outer chambers are in a cut-off state, preventing the guide airflow from blowing out between the first guide opening 611 and the second guide opening 612, and avoiding interference between the two airflows. When the control cam 330 is misaligned with the first control valve 710 and the second control valve 720, the first control valve 710 and the second control valve 720 are in an extended state, both inner chambers are in a cut-off state, and the two outer chambers are in a conducting state. At this time, the guide airflow is circulated, forming an airflow barrier on the outside of the diamond tool processing area, realizing the continuous absorption of polluting gases and dust.

[0050] With the above structural design, there is no need for multiple solenoid valves to coordinate control. The above actions are performed automatically during the rotation of the control cam 330. The cleaning airflow and the guiding airflow are blown out alternately at a predetermined frequency to achieve efficient and continuous absorption of polluting gases and dust. At the same time, the control frequency of the airflow changes synchronously with the rotation speed of the laser generator 400. Automatic control can coordinate with the changes in the amount of polluting gas generated, which is simple and efficient.

[0051] Specifically, the clamping device 500 includes a relatively fixed clamping positioning frame 520, with a clamping body 510 rotatably connected to the inner wall of the clamping positioning frame 520. It also includes a rotating shaft 530 for controlling the clamping body 510 to rotate 180°. The clamping body 510 can be selected as a fixed clamp or a sliding clamp. The sliding clamps can be precisely controlled by a lead screw or other position control structure to achieve accurate clamping and positioning of the diamond tool.

[0052] Meanwhile, the rotating shaft 530 can control the clamping body 510 to rotate 180° as a whole, and can control the diamond tool to rotate 180° in coordination, so that it can be rotated to the other side for laser drilling, reducing the depth of single-sided laser processing, which is suitable for diamond tools with larger thickness.

[0053] The airflow cleaning device 600 is connected to the rotating positioning frame 310 via a telescopic assembly 800. The telescopic assembly 800 includes a telescopic base 810 and a telescopic end 820. The airflow cleaning device 600 is fixedly connected to the telescopic end 820. The telescopic base 810 and the telescopic end 820 can be selected from existing electrically controlled telescopic rod structures or electric slide rail structures, which can control the extension and retraction of the airflow cleaning device 600 at the end. The telescopic assembly 800 is electrically connected to the flipping shaft 530. Before the flipping shaft 530 controls the clamping body 510 to flip, the telescopic assembly 800 is controlled to drive the airflow cleaning device 600 to extend and retract, so that the rotation paths of the airflow cleaning device 600 and the clamping body 510 are staggered to avoid mutual collision.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
