Description

Technical Field

[0001] The present invention relates to the technical field of audio production and processing, and particularly relates to a laser cutting device for skeleton forming in audio processing. Background Art

[0002] The audio skeleton is the box body and support structure of the entire audio system, with high strength, low resonance, and corrosion resistance. The production of in-vehicle audio usually uses aluminum alloy materials, which have the characteristics of light weight and good heat dissipation.

[0003] Currently, during the production and manufacturing of audio skeletons, when performing laser cutting processes, for cutting metal materials, the laser cutting focus needs to be aligned with the material surface to ensure cutting accuracy. For cutting plastic materials, the laser cutting focus needs to be slightly lowered to disperse the surface energy density of the plastic cutting part to prevent burning, optimize the discharge of the melt, and reduce slag. This requires continuous adjustment of cutting parameters when laser cutting different material parts of the audio skeleton, resulting in low cutting efficiency. Moreover, the overall structure of the parts of the audio skeleton that are laser cut is damaged, and a large amount of heat energy is generated, making these parts have certain cutting stresses. However, during the subsequent use of the audio system, its low-frequency resonance state and high-frequency penetration state are likely to cause damage to these stressed holes or cutouts, etc., affecting the subsequent use quality of the audio.

[0032] Example, referring to Figures 1 to 8 , a laser cutting device for frame forming in audio processing, including a control platform 1 and a laser cutting seat 2. A cutting coordinate seat 3 is arranged below the laser cutting seat 2. The control platform 1 is located on the side wall of the cutting coordinate seat 3 and is provided with a plurality of storage grooves. An installation chamber 4 is arranged in the storage groove. The side walls of the installation chamber 4 are respectively communicated with a frequency vibration oil circuit 5 and a limit oil circuit 6. The frequency vibration oil circuit 5 is connected with a hook-shaped pipe 7. A regulating valve 10 is arranged on the hook-shaped pipe 7. The two ends of the hook-shaped pipe 7 are respectively communicated with a commutation groove and an energy storage chamber 8. The inner side wall of the commutation groove is connected with a commutation valve 11. The commutation groove is communicated with a cross pipeline 12. A frequency vibration chamber is arranged in the installation chamber 4. A frequency vibration component is arranged in the frequency vibration chamber. The frequency vibration component is connected with a limit seat 22. An adjustment component is arranged on the side wall of the limit seat 22;

[0033] Further, two hydraulic oil tanks are respectively arranged in the storage grooves of the control platform 1. The two hydraulic oil tanks are respectively communicated with the frequency vibration oil circuit 5 and the limit oil circuit 6. The frequency vibration oil circuit 5 and the limit oil circuit 6 are respectively communicated with the commutation groove. The inner side wall of the energy storage chamber 8 is connected with an energy storage nitrogen chamber 9. The energy storage chamber 8 is communicated with the cross pipeline 12 through the frequency vibration chamber. The inner side wall of the commutation groove is slidably connected with the commutation valve 11. Two inclined pipelines are arranged on the commutation valve 11. One end of the frequency vibration chamber is provided with a nitrogen energy storage chamber 15. Two upper limit plates 14 are fixedly connected to the inner side wall at one end of the frequency vibration chamber. Two lower limit plates 16 are fixedly connected to the inner side wall at the other end of the frequency vibration chamber. An output push column 13 is slidably connected to the inner side wall of the frequency vibration chamber. The frequency vibration component is composed of a return spring 17 and a frequency vibration column 18. The frequency vibration column 18 is slidably connected with the inner side wall at the other end of the frequency vibration chamber. The return spring 17 is sleeved on the outer side wall of the frequency vibration column 18. The end of the frequency vibration column 18 is connected with the limit seat 22 through a universal ball component. The adjustment component is composed of two traction electromagnetic seats 19 and two positioning electromagnetic seats 20. The traction electromagnetic seat 19 is fixedly connected with the installation chamber 4. The positioning electromagnetic seat 20 is fixedly connected with the limit seat 22. The traction electromagnetic seat 19 and the positioning electromagnetic seat 20 are opposite to each other. A plurality of independent electromagnetic regions are arranged on the positioning electromagnetic seat 20. Two opposite limit mechanical arms 21 are respectively fixedly connected to the installation chamber 4 and the limit seat 22;

[0034] It should be noted that: Place the sound skeleton to be cut and processed on the four limit seats 22, and then control the output push rod 13 to apply squeezing and pressing limits to the frequency vibration column 18. When applying squeezing, close the regulating valve 10 on the hook-shaped pipe 7, and then introduce high-pressure hydraulic oil into the frequency vibration oil circuit 5 and the limit oil circuit 6 respectively. Then, the hydraulic oil in the frequency vibration oil circuit 5 enters the reversing groove through the other end of the hook-shaped pipe 7 to press down the reversing valve 11, so that the limit oil circuit 6 is connected to an inclined oil circuit on the reversing valve 11, and high-pressure hydraulic oil is introduced into the cavity above the upper limit plate 14 and the output push rod 13, continuously pressing the output push rod 13 outwards, so as to press tightly on the frequency vibration column 18. Then, the frequency vibration column 18 is pressed to press and limit the sound skeleton to be cut and processed through the limit seat 22, which is convenient for the subsequent cutting and processing of the laser cutting seat 2. When the material to be cut transitions from metal to plastic, according to the required offset angle and distance, first release the limit between the two opposite limit robotic arms 21, and then energize the corresponding electromagnetic area on the positioning electromagnetic seat 20. Utilize the positive magnetic attraction between the energized traction electromagnetic seat 19 and the energized electromagnetic area on the positioning electromagnetic seat 20. Then, during the positive magnetic attraction process, the positioning electromagnetic seat 20 will move the energized electromagnetic area to the traction electromagnetic seat 19, and then synchronously drive the limit seat 22 to move. Among them, the universal ball component compensates for the offset change during the fine-tuning process to finely adjust the position of the sound skeleton on the cutting coordinate seat 3. After adjustment, use the two opposite limit robotic arms 21 for auxiliary limit during docking. The docking and fixing limit between the robotic arms is an existing technology and will not be elaborated here. In this way, the continuous processing of the metal part and the plastic part of the sound skeleton can be achieved, avoiding the cumbersome operation of adjusting and correcting parameters when processing different materials, making the entire processing process more efficient;

[0035] When the overall processing of the sound box skeleton is completed, open the regulating valve 10 on the hook-shaped pipe 7, and only introduce high-pressure hydraulic oil into the frequency vibration oil circuit 5. Then, the hydraulic oil in the frequency vibration oil circuit 5 will flow to both ends of the hook-shaped pipe 7. The hydraulic oil at one end will press down the reversing valve 11 to block the continuous flow of the port of the frequency vibration oil circuit 5, and the hydraulic oil at the other end will flow into the energy storage chamber 8, apply hydraulic pressure to the energy storage nitrogen chamber 9, and at the same time flow into the cavity below the output push rod 13 and the lower limit plate 16, gradually lift the output push rod 13 to the highest point, compress the nitrogen energy storage chamber 15. During the process of lifting the output push rod 13, the cavity below is connected to the cross pipe 12 and high-pressure hydraulic oil is introduced into the other end of the reversing valve 11. Since the hydraulic surface in the cavity below the reversing valve 11 is greater than the hydraulic surface in the cavity above, the reversing valve 11 continuously lifts upward, so that another inclined oil circuit on the reversing valve 11 is connected to the frequency vibration oil circuit 5, thereby introducing the hydraulic oil in the frequency vibration oil circuit 5 into the cavity above the upper limit plate 14 and the output push rod 13. The upward movement of the hydraulic oil will cause the double output push rod 13 to lose support and move downward. The output push rod 13 moves quickly under the action of the high-pressure hydraulic oil and the downward pressure of the nitrogen energy storage chamber 15. After the hydraulic pressure in the energy storage nitrogen chamber 9 decreases, it recovers, presses the hydraulic oil upward to accelerate the output push rod 13, and impacts the frequency vibration column 18. This process repeats, and then high-frequency vibration impact is carried out on the sound box skeleton after cutting processing through the limiting seat 22;

[0036] The benefits based on the above are as follows: This can perform stress relief operations on the sound box skeleton after the overall structure is damaged through high-frequency vibration, and by changing the frequency and intensity of the high-frequency vibration, simulate the frequency vibration state of the sound box skeleton when encountering low-frequency resonance and high-frequency penetration during subsequent use, ensuring that the strength of the sound box skeleton after cutting processing is qualified;

[0037] The top of the laser cutting seat 2 is respectively connected with a nitrogen gas storage tank 23 and a compressed air storage tank 24. The nitrogen gas storage tank 23 and the compressed air storage tank 24 are connected with a transfer hood 26 through a three-way valve 25. The bottom end of the transfer hood 26 is connected with a cooling ring 27, and a heat exchange component for adjusting the output of nitrogen gas and compressed air is arranged in the cooling ring 27;

[0038] Furthermore, the nitrogen gas storage tank 23 and the compressed air storage tank 24 are respectively communicated with both ends of the three-way valve 25 through pipelines. The other end of the three-way valve 25 is communicated with the transfer hood 26 through an inclined pipe. The transfer hood 26 is communicated with the cooling ring 27. The heat exchange component is composed of an impeller part 30 and a plurality of gas collecting pipes 32. Gas collecting holes are formed on the end face of the cooling ring 27. The inner side wall of the gas collecting hole is fixedly connected with the gas collecting pipe 32. An electromagnetic valve 31 is arranged at the end of the gas collecting pipe 32. The inner side wall of the cooling ring 27 is connected with a plurality of electric control storage plates 28. The inner side wall of the cooling ring 27 is rotationally connected with the impeller part 30 through an orifice plate 29;

[0039] It should be noted that: during the laser cutting process, when cutting metal materials, since the metal has fast heat conduction, the pipeline connecting the three-way valve 25 to the nitrogen gas chamber 23 is opened, and the pipeline connecting to the compressed air chamber 24 is closed. Then, the nitrogen gas in the nitrogen gas chamber 23 will enter the cooling ring 27 through the three-way valve 25. At the same time, the solenoid valve 31 on the cooling ring 27 is closed, and the electric control storage plate 28 is opened. Then, the nitrogen gas will impact the impeller part 30 through the orifice plate 29, causing the impeller part 30 to rotate. As a result, the nitrogen gas will be blown out in an outer rotation to uniformly cool the metal cutting part and the edge of the cutting part, avoiding a large temperature difference between the cutting and the cutting edge parts due to cooling, and thus increasing the stress generated by cutting again. When cutting plastic materials, since the plastic has relatively slow heat conduction, the opening and closing state of the three-way valve 25 is opposite to the above, allowing the compressed air in the compressed air chamber 24 to enter the cooling ring 27. At this time, the solenoid valve 31 is opened, and the compressed air is used to centrally cool the plastic cutting part through multiple air collecting pipes 32;

[0040] The benefits based on the above are as follows: This can flexibly adjust the cooling gas for cutting according to the material situation of the processing part during laser cutting, and change the ejection state of the gas during the adjustment process to meet the heat conduction conditions of laser cutting of different materials, resulting in a better cooling effect and reducing the stress generated during the cutting process;

[0041] Two high-frequency hydraulic vibration rods 33 are connected to the back side wall of the laser cutting seat 2, and the output end of the high-frequency hydraulic vibration rod 33 is connected to a vibration damping component;

[0042] Furthermore, the vibration damping component is composed of multiple vibration damping air cushions 34, and the output end of the high-frequency hydraulic vibration rod 33 is fixedly connected to the multiple vibration damping air cushions 34 through a flat plate;

[0043] It should be noted that: during the laser cutting process, the high-frequency hydraulic vibration rod 33 will impact the multiple vibration damping air cushions 34 at the edge of the cutting part, and use the cyclic compression and expansion of the gas in the vibration damping air cushions 34 to buffer and vibrate the edge of the cutting part;

[0044] The benefits based on the above are as follows: Without damaging the cutting part, it further reduces the stress caused by structural damage during the cutting process, ensuring a better cutting effect;

[0045] When the present invention is in use, the sound box skeleton to be cut and processed is placed on the four limit seats 22, and then the output push column 13 is controlled to apply extrusion and pressing limit to the frequency vibration column 18. When applying extrusion, the regulating valve 10 on the hook-shaped pipe 7 is closed, and then high-pressure hydraulic oil is respectively introduced into the frequency vibration oil circuit 5 and the limit oil circuit 6. Then, the hydraulic oil in the frequency vibration oil circuit 5 enters the commutation groove through the other end of the hook-shaped pipe 7 to press down the commutation valve 11, so that the limit oil circuit 6 is connected to an inclined oil circuit on the commutation valve 11 (see the attachmentFigure 5 The upper and lower positions at label 11, that is, when the two diagonal oil passages are connected, high-pressure hydraulic oil is introduced into the cavity above the upper limit plate 14 and the output push rod 13, continuously pressing the output push rod 13 outwards, so as to press tightly on the frequency vibration column 18. Then the frequency vibration column 18 is pressed to press and limit the sound box skeleton to be cut and processed through the limit seat 22, facilitating the subsequent cutting and processing by the laser cutting seat 2. When the material to be cut transitions from metal to plastic, according to the required offset angle and distance, first release the limit between the two opposite limit robotic arms 21, and then energize the corresponding electromagnetic area on the positioning electromagnetic seat 20. Utilize the forward magnetic attraction between the energized traction electromagnetic seat 19 and the energized electromagnetic area on the positioning electromagnetic seat 20. During the forward magnetic attraction process, the positioning electromagnetic seat 20 will move the energized electromagnetic area to align with the traction electromagnetic seat 19, and then synchronously drive the limit seat 22 to move. Among them, the universal ball component compensates for the offset changes during the fine-tuning process to finely adjust the position of the sound box skeleton on the cutting coordinate seat 3. After adjustment, use the two opposite limit robotic arms 21 for auxiliary limit during docking. The docking and fixing limit between the robotic arms is an existing technology and will not be elaborated here. In this way, the continuous processing of the metal part and the plastic part of the sound box skeleton can be achieved, avoiding the cumbersome operation of adjusting and correcting parameters when processing different materials, making the entire processing process more efficient;

[0046] When the overall processing of the sound box skeleton is completed, open the regulating valve 10 on the hook-shaped pipe 7, and only introduce high-pressure hydraulic oil into the frequency vibration oil circuit 5. Then, the hydraulic oil in the frequency vibration oil circuit 5 will flow to both ends of the hook-shaped pipe 7. The hydraulic oil at one end will press down the reversing valve 11 to block the continuous flow of the port of the frequency vibration oil circuit 5, and the hydraulic oil at the other end will flow into the energy storage chamber 8, apply hydraulic pressure to the energy storage nitrogen chamber 9, and at the same time flow into the cavity below the output push rod 13 and the lower limit plate 16, gradually lift the output push rod 13 to the highest point, compress the nitrogen energy storage chamber 15. During the process of lifting the output push rod 13, the cavity below is connected to the cross pipeline 12 and high-pressure hydraulic oil is introduced into the other end of the reversing valve 11. Since the hydraulic oil level in the cavity below the reversing valve 11 is greater than that in the cavity above, the reversing valve 11 continuously lifts upward, enabling another inclined oil circuit on the reversing valve 11 to be connected to the frequency vibration oil circuit 5, thereby introducing the hydraulic oil in the frequency vibration oil circuit 5 into the cavity above the upper limit plate 14 and the output push rod 13. The upward movement of the hydraulic oil will cause the double output push rod 13 to lose support and move downward. The output push rod 13 moves rapidly under the action of the high-pressure hydraulic oil and the downward pressure of the nitrogen energy storage chamber 15. After the hydraulic pressure in the energy storage nitrogen chamber 9 decreases, it recovers, presses the hydraulic oil upward to accelerate the output push rod 13, and impacts the frequency vibration column 18. This process repeats, and then high-frequency vibration impact is performed on the sound box skeleton after cutting processing on the limit seat 22. This can perform stress relief operations of high-frequency vibration on the sound box skeleton after damage to the overall structure, and by changing the frequency and intensity of the high-frequency vibration, simulate the frequency vibration state of the sound box skeleton when encountering low-frequency resonance and high-frequency penetration during subsequent use, ensuring that the strength of the sound box skeleton after cutting processing is qualified;

[0047] During the process of laser cutting, when cutting metal materials, since the heat conduction of metal is relatively fast, open the pipeline connecting the three-way valve 25 to the nitrogen storage tank 23 and close the pipeline connecting to the compressed air storage tank 24. Then, the nitrogen in the nitrogen storage tank 23 will enter the cooling ring 27 through the three-way valve 25. At the same time, the solenoid valve 31 on the cooling ring 27 is closed and the electric control storage plate 28 is opened. Then, the nitrogen will impact the impeller part 30 through the orifice plate 29, causing the impeller part 30 to rotate, and then the nitrogen will be blown out in an outer rotation to evenly cool the metal cutting part and the edge of the cutting part, avoiding large temperature differences in the cutting and cutting edge parts caused by cooling and increasing the stress generated by cutting again. When cutting plastic materials, since the heat conduction of plastic is relatively slow, the opening and closing state of the three-way valve 25 is opposite to the above, allowing the compressed air in the compressed air storage tank 24 to enter the cooling ring 27. At this time, open the solenoid valve 31, and let the compressed air centrally cool the plastic cutting part through multiple air collecting pipes 32. In this way, according to the material situation of the processing part during laser cutting, the cooling gas for cutting can be flexibly adjusted, and the ejection state of the gas can be changed during the adjustment process to meet the heat conduction conditions of different materials during laser cutting, making the cooling effect better and reducing the stress generation during the cutting process;

[0048] During the laser cutting process, the high-frequency hydraulic vibration rod 33 will impact multiple shock-absorbing airbag pads 34 at the edge of the cutting part. By utilizing the cyclic compression and expansion of the gas in the shock-absorbing airbag pads 34, buffer vibration is carried out on the edge of the cutting part. Without damaging the cutting part, the stress caused by structural damage during the cutting process is further reduced, ensuring a better cutting effect.

[0049] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
