Description

Technical Field

[0001] This invention belongs to the field of door and window processing equipment, and specifically discloses a laser cutting device for intelligent door and window processing. Background Technology

[0002] In the traditional door and window processing industry, the cutting of door and window frames and components is usually done by mechanical cutting or manual cutting. These traditional methods have many shortcomings, such as low cutting efficiency, difficulty in ensuring processing accuracy, and high operational difficulty and easy error when cutting complex-shaped door and window components. Therefore, in recent years, some companies have begun to use high-precision laser cutting technology to improve door and window processing equipment.

[0003] In laser processing equipment, auxiliary gas plays an important role, including enhancing the cutting effect, removing slag, cooling, protecting optical components, preventing oxidation, and improving cutting quality. A typical laser contains two jet heads: one that penetrates the laser and emits the laser along with it, and the other that is external and used to cool the workpiece.

[0004] However, in the aforementioned existing technologies, due to the long doors and windows, a large processing space is required, and the gas supply system also requires a large space. In order to ensure safety, the gas supply system is generally set up far away from the processing area. The two are connected by several pipes, but the detection gauge used to warn of problems with the gas supply system is generally set on the gas supply system. Therefore, the staff in the processing area cannot know the operating status of the gas supply system in time, which leads to the inability to shut down the equipment in time when a fault occurs. Without auxiliary gas, the laser head is very easy to be damaged. Summary of the Invention

A closed disk is fixedly connected to the bottom of the fixed ring, and the bottom of the closed disk has evenly distributed cooling holes.

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-7 The laser cutting equipment for intelligent door and window processing shown includes a cutting platform 1. A fixing mechanism 2 is provided on the top of the cutting platform 1 to fix the door and window frame. A support frame 3 is fixedly connected to the top of the cutting platform 1. A moving mechanism is provided on the top of the cutting platform 1. A laser 10 is provided at one end of the moving mechanism. The moving mechanism is used to adjust the specific position of the laser 10 for cutting and drilling. An inlet pipe 13 and a cooling pipe 14 are fixedly connected to both sides of the laser 10, respectively. The cooling pipe 13 is used to supply auxiliary gas into the laser 10, and the inlet pipe 14 is used to cool the cutting part to prevent deformation. An alarm conversion component is provided on the outside of the laser 10. The alarm conversion component is used to indicate whether the inlet pipe 13, which supplies auxiliary gas into the laser 10, is supplying it normally. When the inlet pipe 13 stops or fails to supply auxiliary gas into the laser 10, the alarm conversion component can promptly supply the auxiliary gas in the cooling pipe 14 into the laser 10. The alarm conversion component is connected to the laser 10. Both the cooling pipe 13 and the inlet pipe 14 are connected to an external gas supply system.

[0028] The user places the door and window material to be cut on the cutting platform 1 beforehand, and then adjusts the fixing mechanism 2 to clamp and fix it. After confirming that the fixing is completed, the user starts the device through the controller. The position of the laser 10 is adjusted by the cooperation of the first moving mechanism 5, the second moving mechanism 7 and the third moving mechanism 9, and then the door and window material clamped and fixed by the fixing mechanism 2 is cut and drilled. By setting an alarm conversion component, the user at the processing site can also be informed of the supply of auxiliary gas in a timely manner. When the auxiliary gas transmission system used to cool the inside of the laser 10 malfunctions, it can be detected in time and changes can be made to ensure that the auxiliary gas used to cool the door and window material being cut is introduced into the inside of the laser 10 in a timely manner, so as to avoid damage to the internal structure of the laser 10 due to the lack of auxiliary gas.

[0029] The moving mechanism includes a first moving mechanism 5 located on top of the cutting platform 1. A support base 6 is located on top of the first moving mechanism 5, allowing the first moving mechanism 5 to adjust the position of the support base 6 for parallel movement. A second moving mechanism 7 is located on top of the support base 6, and a mounting plate 8 is located on one side of the second moving mechanism 7. The second moving mechanism 7 can adjust the position of the mounting plate 8 to cooperate with the first moving mechanism 5 in cross-movement. A third moving mechanism 9 is located on one side of the mounting plate 8 and is fixedly connected to one side of the laser 10. The third moving mechanism 9 is used to adjust the vertical height of the laser 10. Each of the first moving mechanism 5, the second moving mechanism 7, and the third moving mechanism 9 includes a drive mechanism, a sliding base, and a slide rail. Through the combined operation of the first moving mechanism 5, the second moving mechanism 7, and the third moving mechanism 9, and under the adjustment of the PLC controller, the laser 10 can move flexibly.

[0030] The laser 10 includes a connecting part 20, a driving part 18 fixedly connected to one side of the connecting part 20, an optical fiber interface 19 fixedly connected to the top of the connecting part 20 for receiving optical fiber input, a focusing part 21 fixedly connected to the bottom of the connecting part 20 for focusing the optical fiber, a cooling part 24 fixedly connected to the bottom of the focusing part 21 for cooling the emitting part 25 and its cutting area, and the emitting part 25 fixedly connected to the bottom of the cooling part 24. A straightening channel 31 is formed inside the emitting part 25, and the auxiliary gas and laser are mixed from the straightening channel 31. The bottom of the emitting part 25 is fixedly connected to the emitting head 26. The outer wall of the cooling part 24 is fixedly connected to the cooling connector 23, and the cooling connector 23 is connected to the cooling pipe 14. The inlet pipe 14 delivers the auxiliary gas for cooling to the interior of the cooling part 24. The outer wall of the emitting part 25 is fixedly connected to the inlet connector 22, and the inlet connector 22 is connected to the inlet pipe 13. The auxiliary gas delivered at the inlet connector 22 enters the interior of the emitting part 25 and is emitted together with the laser through the straightening channel 31. The gas blown out can be used to protect the internal focusing lens from debris.

[0031] Both the inlet pipe 13 and the cooling pipe 14 are equipped with solenoid valves 11 on their outer walls. By setting the solenoid valves 11, the connection and blockage between the cooling pipe 13 and the inlet pipe 14 can be adjusted. The bottom of the solenoid valve 11 is fixedly connected to a fixing member 4, which is fixedly connected to the top of the support frame 3. The fixing member 4 is used to fix the cooling pipe 13 and the inlet pipe 14 to prevent them from getting tangled together or overlapping due to the traction of the moving mechanism, which would obstruct the air passage and interfere with the air supply. The outer wall of the inlet pipe 13 is equipped with a gauge 12, which is used to detect the air supply inside the cooling pipe 13 in real time. Since the gauge 12 is located in the working area, it is convenient for operators at the processing site to understand the auxiliary gas delivery status in a timely manner. One side of the fixing member 4 is equipped with a vertical plate 15, which is fixedly connected to the top of the support frame 3. The bottom of the inner wall of the vertical plate 15 is fixedly connected to two pipe clamps 16, which are respectively fitted onto the outside of the inlet pipe 13 and the cooling pipe 14. The pipe clamp 16 is used to guide and secure the cooling pipe 13 and the inlet pipe 14.

[0032] A fixed ring 37 is fixedly connected inside the cooling section 24. The outer wall of the fixed ring 37 has evenly distributed blocking holes 40. A sealing plate 39 is fixedly connected to the bottom of the fixed ring 37, sealing the internal space of the cooling section 24. The bottom of the sealing plate 39 has evenly distributed cooling holes 29. A rotating ring 34 is fitted around and rotatably connected to the outside of the fixed ring 37. A gear ring 35 is fixedly connected to the top of the rotating ring 34. Evenly distributed cooling holes 36 are opened on the outer wall of the rotating ring 34, corresponding to the blocking holes 40. The 37 blocks the 36, preventing auxiliary gas from entering from point 14. Evenly distributed connecting holes 30 are opened at the bottom of the rotating ring 34, corresponding to 29. Auxiliary gas entering from point 14 exits through these holes. A micro motor 32 is fixedly connected to the outer wall of the focusing section 21. The output end of the micro motor 32 is fixedly connected to a gear 33 via a shaft, and the gear 33 and the gear... When the micro motor 32 starts, it drives the gear 33 to rotate. Through the meshing relationship between the two, the gear ring 35 is driven to rotate. The gear ring 35 then drives the rotating ring 34 to rotate on the fixed ring 37. Correspondingly, the connecting hole 30 and the cooling hole 36 rotate, and their positions change. Therefore, they change their matching relationship with the cooling hole 29 and the blocking hole 40. That is, the connecting hole 30 no longer exposes the cooling hole 29, so that the air passage is blocked. The blocking hole 40 corresponds to the cooling hole 36, so that the air passage is open. The auxiliary gas at the inlet tube 14 enters the interior of the launching part 25 through the cooling part 24 and replaces the cooling pipe 13 to perform auxiliary work. Several connecting pipes 28 are fixedly connected to the bottom of the cooling part 24. The other end of the connecting pipe 28 is fixedly connected to the jet head 27. The jet head 27 is fixedly connected to the outer wall of the launching part 25 through a rotating shaft. Through this design, the orientation position of the jet head 27 can be adjusted to change the cooling part.

[0033] Auxiliary gas is supplied through an external gas supply system to the cooling pipe 13 and the inlet pipe 14, respectively. It then enters the emitting section 25 and the cooling section 24 via the inlet connector 22 and cooling connector 23, respectively. The auxiliary gas entering the emitting section 25 mixes with the laser at the straightening channel 31 inside the emitting section 25 and is ejected from the emitting head 26. The gas entering the cooling section 24 lingers within it. Under normal circumstances, the rotating ring 34 blocks the shielding hole 40, while the cooling hole 29 is exposed inside the connecting hole 30. Therefore, the auxiliary gas inside the cooling section 24 enters the connecting pipe 28 through the cooling hole 29 and is then ejected from the jet head 27 to cool the cut area. In case of a malfunction, the solenoid valve 11 at the cooling pipe 13 automatically closes. At this time, the micro motor 32 is energized and executes a predetermined program, driving the gear 33 to rotate. The drive gear ring 35 and the rotating ring 34 rotate synchronously. At this time, affected by the rotation of the rotating ring 34, the alignment of the holes under normal conditions changes. The connecting hole 30 gradually covers the cooling hole 29, while the bottom of the rotating ring 34 forms a shield, thus sealing the cooling hole 29. The cooling hole 36 gradually coincides with the shielding hole 40 and gradually forms a connection. At this time, the auxiliary gas enters the interior of the firing part 25 from the shielding hole 40, thus ensuring that the interior of the firing part 25 is continuously filled with auxiliary gas, protecting the internal focusing lens and improving the cutting effect. By setting the cooling part 24, the auxiliary gas entering from the cooling pipe 13 lingers inside the cooling part 24 and enters the interior of the jet head 27 through the connecting pipe 28. Through this design, multiple jet heads 27 can be set to receive the auxiliary gas from the cooling part 24, so that the airflow blown out can cover a larger area and cool a larger area.

[0034] The outer walls of the inlet pipe 13 and the cooling pipe 14 are jointly fitted with a constraint sleeve 17. By setting the constraint sleeve 17, the protective performance of the cooling pipe 13 and the inlet pipe 14 can be enhanced, thus playing a protective role.

[0035] The diameter of the connecting hole 30 is greater than the diameter of the cooling hole 29. With this design, the connecting hole 30 is easier to connect with the cooling hole 29.

[0036] The outer wall of the closed disk 39 is provided with several pressure relief holes 38. When the connecting hole 30 no longer exposes the cooling hole 29, the inlet pipe 14 continues to supply auxiliary gas into the interior of the cooling section 24. With this design, when the connecting hole 30 rotates, the pressure relief holes 38 will be exposed, and the auxiliary gas will be released to the outside of the cooling section 24 through the pressure relief holes 38, preventing the internal pressure of the cooling section 24 from rising rapidly and damaging the structure.

[0037] Working principle:

[0038] Before use, the user should check whether the device is damaged. After confirming that the device is undamaged, the user should place the door and window material to be cut on the cutting platform 1, and then adjust the fixing mechanism 2 to clamp and fix it. After confirming that the fixing is completed, the user starts the device through the controller and adjusts the position of the laser 10 through the cooperation of the first moving mechanism 5, the second moving mechanism 7 and the third moving mechanism 9, so as to cut and drill the door and window material clamped and fixed by the fixing mechanism 2.

[0039] The auxiliary gas delivery process is as follows: An external gas supply system supplies auxiliary gas to the cooling pipe 13 and the inlet pipe 14, respectively. The auxiliary gas then enters the emitting section 25 and the cooling section 24 via the inlet connector 22 and cooling connector 23, respectively. The auxiliary gas entering the emitting section 25 mixes with the laser at the straightening channel 31 inside the emitting section 25 and is ejected from the emitting head 26. The gas entering the cooling section 24 lingers within it. Under normal circumstances, the rotating ring 34 blocks the shielding hole 40, while the cooling hole 29 is exposed inside the connecting hole 30. Therefore, the auxiliary gas inside the cooling section 24 enters the connecting pipe 28 through the cooling hole 29 and is then ejected from the jet head 27, thus cutting the area. During cooling, if a malfunction occurs, the solenoid valve 11 located at the cooling pipe 13 will automatically close. At this time, the micro motor 32 will be energized and execute a predetermined program, driving the gear 33 to rotate. The gear 33 will then drive the gear ring 35 and the rotating ring 34 to rotate synchronously. At this time, affected by the rotation of the rotating ring 34, the alignment of the holes under normal conditions will change. The connecting hole 30 will gradually cover the cooling hole 29, while the bottom of the rotating ring 34 will block it, thus sealing the cooling hole 29. The cooling hole 36 will gradually coincide with the blocking hole 40 and gradually form a through connection. At this time, the auxiliary gas will enter the interior of the emitting part 25 from the blocking hole 40, thereby ensuring that the interior of the emitting part 25 is continuously filled with auxiliary gas, protecting the internal focusing lens and improving the cutting effect.
