Description

Technical Field

[0001] The present invention belongs to the technical field of laser processing, and particularly relates to a cutting device and a cutting method for a stage lighting lens. Background Art

[0002] In modern stage performances, the presentation of lighting effects occupies a crucial position. As the core component for achieving specific light effects, the design and production of stage lighting lenses are directly related to the visual presentation of the entire performance. With the rapid development of stage lighting technology, the requirements for the quality and processing accuracy of lenses are also continuously increasing. Currently, the production of stage lighting lenses mostly uses traditional cutting techniques, but these traditional methods generally have drawbacks such as low accuracy, poor surface quality, and low processing efficiency. In order to better meet the needs of modern stage lighting, manufacturers have continuously introduced new laser cutting devices for lens processing. For example, a cutting device for a stage lighting lens with the application number CN202221795391.7. By turning on the laser cutting component, this device can cut the lens, and by turning on the air pump, the waste gas can be pumped into the purification box for purification and then discharged, thus avoiding the waste gas being inhaled by the staff and affecting their physical health.

[0003] Although there are already various cutting devices for lens processing on the market, there are still many challenges in practical applications. Current laser cutting equipment generally uses high-energy laser beams, which not only brings potential safety risks but also requires the equipment to strictly seal the processing area to prevent laser leakage from harming operators and the surrounding environment. In addition, by introducing auxiliary gas into the processing area, it is possible to effectively isolate oxygen in the air, prevent material oxidation, and at the same time control the sparks and dust generated during the cutting process, further improving the cutting accuracy and surface smoothness. However, when it is necessary to replace the lens after processing is completed, the sealed area must be opened, which not only causes the loss of auxiliary gas but also destroys the established sealed environment. In the long run, frequent opening and closing of the seal not only increases the maintenance cost of the equipment but also reduces the overall efficiency of use. The sealing treatment is to prevent laser leakage from harming operators and the surrounding environment. In addition, by introducing auxiliary gas into the processing area, it is possible to effectively isolate oxygen in the air, prevent material oxidation, and at the same time control the sparks and dust generated during the cutting process, further improving the cutting accuracy and surface smoothness. However, when it is necessary to replace the lens after processing is completed, the sealed area must be opened, which not only causes the loss of auxiliary gas but also destroys the established sealed environment. In the long run, frequent opening and closing of the seal will not only increase the consumption of auxiliary gas but also have a negative impact on the sealing performance of the equipment, thereby affecting the stability and safety of processing. If the sealing performance deteriorates, it may lead to an increased risk of laser leakage, and at the same time, it will also affect the protective effect of the auxiliary gas, making the material more likely to oxidize during the cutting process and affecting the quality of the finished product.

Therefore, it will not be elaborated in this embodiment.

[0037] Embodiment 1

[0038] See Figure 1 , a cutting device for a stage lighting lens. The cutting device includes a processing chamber 1, a transfer chamber 2, and a placement chamber 3. The processing chamber 1, the transfer chamber 2, and the placement chamber 3 are all hermetically arranged. The transfer chamber 2 is used to connect the processing chamber 1 and the placement chamber 3; the chambers are connected through specific interfaces to ensure that the laser and auxiliary gas in the processing chamber 1 do not leak during the lens transmission process. A laser cutting assembly 4 is provided in the processing chamber 1, and the laser cutting assembly 4 is used to perform cutting operations on the lens; the laser cutting assembly 4 is composed of a motor turntable and a laser emitter. A turntable is key-connected to the output shaft of the motor, and a laser emitter is installed at an eccentric position at the bottom of the turntable; the laser emitter rotates with the turntable to achieve precise multi-angle cutting of the lens. An auxiliary gas system is also equipped on the laser emitter, and the auxiliary gas system provides the auxiliary gas required during the cutting process; different gases are suitable for different materials and cutting methods, which helps to improve the cutting speed and quality; among them, stage lighting lenses have extremely high requirements for surface quality and transparency, and usually nitrogen is selected as the auxiliary gas to ensure that the cutting surface is free of oxidation and impurities and maintain the optical performance of the lens. A material placement platform 211 is provided in the transfer chamber 2, and the material placement platform 211 is used for placing and fixing the lens; the lens is transmitted by moving the material placement platform 211 between the processing chamber 1 and the placement chamber 3, thereby avoiding the leakage of laser and auxiliary gas in the processing chamber 1. By introducing the transfer chamber 2, efficient transmission of the lens between different chambers is achieved, and problems caused by frequent opening of the sealed area in the traditional single-chamber design, such as loss of auxiliary gas and decline in sealing performance, are solved.

[0039] See Figure 1 , Figure 2, the cutting device further includes a workbench 5. The workbench 5 serves as the foundation of the entire device, providing support and an installation platform. The workbench 5 is divided into a front area and a back area. Among them, the processing chamber 1 and the placement chamber 3 are arranged on the front of the workbench 5, and the processing chamber 1 is arranged on the back of the workbench 5; the processing chamber 1 is composed of a processing cover body 11 and a processing base 12, and the placement chamber 3 is composed of a placement cover body 31 and a placement base 32; both the placement base 32 and the processing base 12 are provided with docking ports 33 communicating with the transfer chamber 2. The docking port 33 is the opening for the material placement platform 211 to enter the processing chamber 1 and the placement chamber 3. The docking port 33 adopts a sealing structure to ensure that the airtightness of the processing chamber 1 will not be damaged during the lens transmission process.

[0040] See Figure 3 , partition plates 34 are movably arranged on both the processing base 12 and the placement base 32. The partition plates 34 are used to control the opening and closing of the docking ports 33; when the partition plates 34 close the docking ports 33, the transfer chamber 2 and the processing chamber 1 or the transfer chamber 2 and the placement chamber 3 are in a disconnected state; when the partition plates 34 open the docking ports 33, the transfer chamber 2 and the processing chamber 1 or the transfer chamber 2 and the placement chamber 3 are in a connected state, allowing the material placement platform 211 to enter the corresponding chamber through the docking ports 33. Sealing members are arranged around the material placement platform 211; when the docking ports 33 are opened, the material placement platform 211 enters the processing chamber 1 or the placement chamber 3 from the docking ports 33, and the sealing members keep the transfer chamber 2 and the processing chamber 1 or the transfer chamber 2 and the placement chamber 3 in a disconnected state; when the material placement platform 211 enters the processing chamber 1 or the placement chamber 3 from the docking ports 33, the sealing members will closely fit the docking ports 33 to ensure the airtightness between the transfer chamber 2 and the processing chamber 1 or between the transfer chamber 2 and the placement chamber 3.

[0041] See Figure 7 , both the processing cover body 11 and the placement cover body 31 are provided with control frames 51. The control frames 51 are composed of telescopic columns 52 and connecting rods 53. The control frames 51 are used to control the opening and closing of the processing chamber 1 and the placement chamber 3.

[0042] The cutting device further includes a gas treatment system. The gas treatment system includes a gas collection box, a purification box, and exhaust pipes respectively arranged in the processing chamber 1, the transfer chamber 2, and the placement chamber 3; the exhaust pipes are connected to the gas collection box, and the gas collection box is connected to the purification box; the gas collection box, the purification box, and the exhaust pipes are used to collect and purify the waste gas generated during the cutting process, and the suction force of the exhaust pipes can also be used to collect the waste materials generated during the cutting process.

[0043] A linear drive component is provided inside the transfer cabin 2. The linear drive component is divided into a first linear drive component and a second linear drive component. The second linear drive component is arranged on the moving end of the first linear drive component, and the material placing platform 211 is arranged on the moving end of the second linear drive component. The linear drive component is used to control whether the material placing platform 211 enters the docking port 33 and to control the movement of the material placing platform 211 between the processing cabin 1 and the placing cabin 3.

[0044] Embodiment 2

[0045] This embodiment relates to a cutting device for stage lighting lenses. Compared with the cutting device for stage lighting lenses in Embodiment 1, the internal structure of the transfer cabin 2 is optimized in this embodiment as follows:

[0046] A rotating platform is arranged inside the transfer cabin 2, and a lifting platform is arranged on the rotating platform. The moving end of the lifting platform is connected to the material placing platform 211. The rotating platform is used to control the movement of the material placing platform 211 between the processing cabin 1 and the placing cabin 3, and the lifting platform is used to control whether the material placing platform 211 enters the docking port 33. Through the rotating platform, precise movement of the material placing platform 211 in different directions can be achieved. This design ensures more accurate positioning of the material placing platform 211 when entering the processing cabin 1 and the placing cabin 3, reducing errors that may be caused by manual operation or simple linear movement. The lifting platform can control the vertical movement of the material placing platform 211 to ensure that the height of the material placing platform 211 is consistent when entering the docking port 33, avoiding problems such as jamming or poor sealing caused by inconsistent heights.

[0047] Specifically, the linear drive component in Embodiment 1 can only drive one material placing platform 211, which is used to carry the lenses to be processed or already processed. Only one lens can be processed at a time, and it is necessary to wait for one lens to complete processing and be unloaded before starting to place the next lens, resulting in relatively low overall working efficiency. Compared with Embodiment 1, in Embodiment 2, multiple lifting platforms can be arranged on the rotating platform inside the transfer cabin 2, realizing parallel processing of multiple material placing platforms 211. Each material placing platform 211 can independently carry the lenses to be processed or already processed. When one lens is being cut, other material placing platforms 211 can prepare new lenses in advance, realizing parallel processing. This significantly shortens the overall processing time and improves production efficiency. At the same time, the design of multiple material placing platforms 211 enables the equipment to operate continuously, reducing the idle time of the equipment. During the process of waiting for the next lens to enter the processing cabin 1, the equipment can continue to process other lenses, improving the utilization rate of the equipment. Moreover, due to the design of multiple material placing platforms 211, the operator can place multiple lenses at one time, reducing the frequency of operating the equipment and lowering the operation risk.

[0048] Embodiment III

[0049] This embodiment relates to a cutting device for stage lighting lenses. Compared with the cutting device for stage lighting lenses in Embodiment I and Embodiment II, the internal structure of the transfer cabin 2 is optimized in this embodiment as follows:

[0050] See Figure 5 、 Figure 6 , a rotating frame 22 is arranged in the transfer cabin 2. A support rod 23 is swingably arranged on the rotating frame 22. The other end of the support rod 23 is rotatably connected to the material placing platform 211. A telescopic member 24 is arranged below the docking port 33, and the telescopic member 24 is installed on the transfer cabin 2. The rotating frame 22 controls the movement of the material placing platform 211 between the processing cabin 1 and the placing cabin 3 through the support rod 23. The telescopic member 24 is used to control whether the material placing platform 211 enters the docking port 33. When the material placing platform 211 rotates above the telescopic member 24, the telescopic member 24 pushes the material placing platform 211 towards the docking port 33. A return spring is arranged between the material placing platform 211 and the support rod 23, and the return spring is used to keep the material placing platform 211 stable during movement, reduce shaking and vibration, and improve the smoothness of operation.

[0051] See Figure 4 , a limiting plate 212 is arranged at the bottom end of the material placing platform 211, and a positioning protrusion 213 is arranged on the limiting plate 212. A positioning groove 214 is formed on the back surface of the workbench 5. When the telescopic member 24 controls the material placing platform 211 to enter the docking port 33, the positioning protrusion 213 and the positioning groove 214 prevent the material placing platform 211 from bumping into the workbench 5, ensuring the precise alignment of the material placing platform 211 when entering the docking port 33, avoiding bumping into the workbench 5, and further improving the stability and safety of the equipment.

[0052] Specifically, this embodiment is similar to Embodiment 2 and can also achieve parallel processing of multiple material placement platforms 211. When a lens is being cut, other material placement platforms 211 can prepare new lenses in advance, significantly shortening the overall processing time. Inheriting the advantages of Embodiment 2, the optimization is as follows: In Embodiment 2, each material placement platform 211 requires an independent lifting platform to control its vertical movement, which requires multiple telescopic mechanisms. In Embodiment 3, only one telescopic component 24 is needed to control the entry and exit of all material placement platforms 211 to the docking interface 33. This greatly simplifies the structure of the device, reduces the number of mechanical components, and lowers the manufacturing and maintenance costs. Since the number of telescopic components 24 is reduced, the failure points of the device are also reduced, improving the reliability and stability of the device.

The cutting method includes:

[0063] S7. Move the material placement platform 211 into the placement chamber 3 to remove the processed lenses and place the lenses to be processed, and prepare for the next round of cutting operations.

[0064] In addition, as common general knowledge in this industry, the linear drive components, rotating platforms, lifting platforms, rotating frames 22, and telescopic components 24 mentioned above are all provided with independent drive devices (motors) and gas treatment systems. The above is common general knowledge, so the principles and structures thereof will not be described in detail herein.
