Description
Technical Field
[0001] This utility model relates to the field of laser drilling technology, specifically a laser galvanometer drilling device for a Bluetooth microphone in an automotive roof. Background Technology
[0002] In automotive manufacturing, traditional plastic microphones have gradually been replaced by a set of 1mm holes machined directly into the car roof. These holes are called "plum blossom holes" due to their unique layout. To ensure stable transmission and reception of Bluetooth signals, the machining precision of the plum blossom holes is extremely high.
[0003] However, the existing processing method mainly uses a light guide arm to transmit the laser to the cutting head, and then the motion mechanism at the end of the robot drives the cutting head to complete the cutting of the small hole. The robot's own motion accuracy cannot meet the requirement of controlling the roundness within 0.05mm when cutting a 1mm small hole. In addition, the additional light guide arm not only makes the equipment structure more complicated, but also has low drilling efficiency, making it difficult to further improve the production speed.
[0004] Therefore, it is necessary to design a laser galvanometer drilling device for automotive roof Bluetooth microphones with high drilling accuracy and high processing efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a laser galvanometer drilling device for a car roof Bluetooth microphone, in order to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a laser galvanometer drilling device for a car roof Bluetooth microphone, comprising a mounting plate, a CO2 laser for emitting CO2 laser is mounted on the top of the mounting plate, a red light module for emitting guiding red light is mounted on one side of the bottom of the mounting plate, and a galvanometer module for refracting CO2 laser light is mounted on the other side of the bottom of the mounting plate. A refraction module for guiding CO2 laser light into the galvanometer module is connected to the bottom of the red light module, and the refraction module is connected to the galvanometer module.
[0007] According to the above technical solution, a red light emitter is installed on one side of the red light module, and the emitting end of the CO2 laser is located at the upper end of the red light module. A 45° glass refracting mirror is also provided in the red light module to refract and guide the red light.
[0008] According to the above technical solution, the galvanometer module is provided with a galvanometer cavity. A laser inlet is provided on one side of the galvanometer cavity. A lower swinging mirror for refracting the CO2 laser entering from the laser inlet is installed on the side of the laser inlet of the galvanometer cavity. An upper swinging mirror for refracting the CO2 laser refracted by the lower swinging mirror onto the car roof to be drilled is installed on the side of the lower swinging mirror of the galvanometer cavity.
[0009] According to the above technical solution, a refractive cavity is provided between the red light module and the refractive module, and a refractive mirror is provided inside the refractive cavity.
[0010] According to the above technical solution, a laser tube is connected to the flange on the side of the refraction module near the galvanometer module, and the other end of the laser tube is connected to the flange of the galvanometer module.
[0011] According to the above technical solution, a beam expander is installed on the flange of the laser emitting end of the CO2 laser.
[0012] According to the above technical solution, the bottom of the galvanometer module is provided with a laser outlet, and the laser outlet is connected to a focusing cover.
[0013] According to the above technical solution, the mounting plate is provided with a protective cover at the CO2 laser mounting location to protect the CO2 laser.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: Equipped with a CO2 laser, a red light module, a galvanometer module, and a refraction module, this device enables precise drilling of car roof panels. The CO2 laser emits a CO2 beam that passes through a 45° glass refractor. Simultaneously, a visible guide red light is emitted from a red light emitter on one side of the red light module, which is then refracted by the 45° glass refractor to be coaxial with the CO2 laser. This provides a visual laser path for the invisible CO2 laser, allowing operators to easily observe the processing area and position for program adjustments. The refractor in the refraction module stably guides the CO2 laser into the galvanometer module, ensuring a stable transmission path. The galvanometer module allows the CO2 laser to be refracted within a specific plane. Through the coordinated action of internal lower and upper oscillating mirrors, the irradiation position of the CO2 laser can be flexibly adjusted to meet drilling requirements at different locations. This eliminates the need for frequent movement of the entire device, significantly improving drilling flexibility and work efficiency. Attached Figure Description

[0016] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0017] This utility model provides a technical solution: a laser galvanometer drilling device for a car roof Bluetooth microphone, including a mounting plate 10. A CO2 laser 20 for emitting CO2 laser is mounted on the top of the mounting plate 10. A red light module 30 for emitting guiding red light is mounted on one side of the bottom of the mounting plate 10. A galvanometer module 40 for refracting CO2 laser light is mounted on the other side of the bottom of the mounting plate 10. A refraction module 50 for guiding CO2 laser light into the galvanometer module 40 is connected to the bottom of the red light module 30. The refraction module 50 is connected to the galvanometer module 40.
[0018] This technical solution achieves integrated and precise design for processing the quincunx holes of Bluetooth microphones in car roofs. The non-visible laser provided by the CO2 laser 20 serves as the energy source for drilling, and the coaxial guiding red light emitted by the red light module 30 allows for direct confirmation of the laser's position. The refraction module 50 stably guides the CO2 laser into the galvanometer module 40, which then controls the laser path within a specific plane through light point refraction. The overall structure is simplified and the processing efficiency is high.
[0019] Furthermore, a red light emitter 31 is installed on one side of the red light module 30, and the emitting end of the CO2 laser 20 is located at the upper end of the red light module 30. A 45° glass refracting mirror is also provided in the red light module 30 to refract and guide the red light.
[0020] With this technical solution, the CO2 laser 20 emits a CO2 laser beam that passes through a 45° glass refractor. At the same time, the red light emitter 31 on one side of the red light module 30 emits visible guiding red light, which is then refracted by the 45° glass refractor to be coaxial with the CO2 laser. This provides a visual laser path for the CO2 laser, which is invisible to the naked eye, making it easier for operators to observe the processing area and position of the CO2 laser and then debug the program.
[0021] Furthermore, the galvanometer module 40 is provided with a galvanometer cavity 41. A laser inlet 42 is provided on one side of the galvanometer cavity 41. A lower swing mirror 43 for refracting the CO2 laser entering from the laser inlet 42 is installed on the side of the galvanometer cavity 41. An upper swing mirror 44 for refracting the CO2 laser refracted by the lower swing mirror 43 onto the car roof to be drilled is installed on the side of the galvanometer cavity 41.
[0022] With this technical solution, the lower swing lens 43 initially refracts the CO2 laser entering from the laser inlet 42, and the upper swing lens 44 then precisely refracts it onto the car roof to be drilled. Through the synergistic effect of the two, the cutting of the quincunx hole can be completed quickly, further improving the cutting efficiency.
[0023] Furthermore, a refractive cavity 51 is provided between the red light module 30 and the refractive module 50, and a refractive mirror 52 is provided inside the refractive cavity 51.
[0024] Through this technical solution, the refractive cavity 51 provides a stable installation space for the refractive mirror 52, which can efficiently refract the CO2 laser emitted by the CO2 laser 20 to the galvanometer module 40.
[0025] Furthermore, a laser tube 53 is connected to the flange on the side of the refraction module 50 near the galvanometer module 40, and the other end of the laser tube 53 is connected to the flange of the galvanometer module 40.
[0026] Through this technical solution, the laser tube 53 uses a flange connection to firmly connect the refraction module 50 and the galvanometer module 40, forming a closed laser transmission channel. This can effectively reduce the energy loss of CO2 laser during transmission, while preventing external environmental factors from interfering with the laser beam, ensuring that the laser enters the galvanometer module 40 with stable energy and path.
[0027] Furthermore, a beam expander 21 is installed on the laser emitting flange of the CO2 laser 20.
[0028] Through this technical solution, the beam expander 21 can adjust the beam of the CO2 laser emitted by the CO2 laser 20 and optimize the focusing performance of the laser.
[0029] Furthermore, a laser outlet 45 is provided at the bottom of the galvanometer module 40, and a focusing cover 46 is connected to the laser outlet 45.
[0030] With this technical solution, the laser outlet 45 is the channel through which the laser is finally emitted to the car roof, and the focusing cover 46 can optimize the focusing of the emitted laser, enhance the energy density of the laser, reduce the diffusion of the laser, and improve the energy utilization rate.
[0031] Furthermore, the mounting plate 10 is provided with a protective cover 11 at the mounting location of the CO2 laser 20 to protect the CO2 laser 20.
[0032] Through this technical solution, the protective cover 11 can provide effective protection for the CO2 laser 20, preventing it from being affected by external collisions, dust, water vapor and other factors during equipment operation, thus extending the service life of the CO2 laser 20.
[0033] Working principle: First, the CO2 laser 20 is started and emits a CO2 laser for drilling. The CO2 laser first passes through the beam expander 21 at the transmitting end. The beam expander 21 shapes and expands the CO2 laser to optimize its focusing performance. Meanwhile, the CO2 laser passes through the 45° glass refractor, and the red light emitter 31 on one side of the red light module 30 emits visible guiding red light. Subsequently, the guiding red light is refracted by the 45° glass refractor to be coaxial with the CO2 laser, providing a visual laser path for the CO2 laser that is invisible to the naked eye. This makes it easier for operators to observe the processing area and position of the CO2 laser and then debug the program. Next, the adjusted CO2 laser enters the refraction mirror 52 in the refraction cavity 51 between the red light module 30 and the refraction module 50. The CO2 laser is refracted under the action of the refraction mirror 52, thereby changing the path of the CO2 laser and transmitting it to the galvanometer module 40. Subsequently, the CO2 laser continues to be transmitted to the galvanometer module 40 through the closed laser conduction channel formed by the laser tube 53 connected by the flange; After entering the galvanometer module 40, the CO2 laser enters the galvanometer cavity 41 from the laser inlet 42. The lower oscillating lens 43 initially refracts the incoming CO2 laser, changing the direction of its propagation. Subsequently, the CO2 laser is refracted to the upper oscillating lens 44, which refracts the CO2 laser again. The focusing mask 46 optimizes the focusing of the CO2 laser, enabling it to be precisely directed from the laser outlet 45 onto the car roof to be drilled. The CO2 laser quickly and accurately completes the cutting of 1mm quincunx holes on the car roof.
