Description

Technical Field

[0001] The utility model relates to the technical field of vehicle production, in particular to a laser drilling system for an automobile bumper. Background Art

[0002] During automobile production, holes are drilled into the surface or structure of the bumper according to design requirements. These holes are typically used to install various components such as sensors, lights, cameras, and decorative parts, or to provide support for subsequent assembly. Drilling holes is not only for aesthetic and structural requirements but also involves functional considerations, such as air circulation, temperature sensor installation location, and collision sensor placement.

[0003] Currently, the combination of laser drilling, stamping, CNC drilling, and robotic automation has made the bumper drilling process in modern automobile production more efficient, precise, and flexible. While technological advancements have enabled advancements in bumper drilling equipment, some challenges remain. The heating, cutting, and friction processes involved in bumper drilling generate significant amounts of smoke and dust, which release harmful substances into the air. This smoke and dust, particularly in poorly ventilated environments, can degrade air quality and contribute to indoor pollution. Long-term exposure to these conditions is not only harmful to operators but also to the health of others around them. This not only negatively impacts worker health, production equipment, and the environment, but can also compromise the quality of the final product. Therefore, effective protective measures and control measures are crucial. Utility Model Content

[0053] The housing component 10 includes a frame structure, an independent processing space is formed inside the frame structure, and a punching station is formed in the processing space. The punching station is mainly used to process the automobile bumper 90;

[0054] The smoke removal component 20 includes a smoke control cabinet 21, an air suction pipe 22 and an air outlet pipe 23; the smoke removal component 20 is arranged outside the processing space, and one end of the air suction pipe 22 is connected to the smoke control cabinet 21, and the other end is connected to the frame structure; one end of the air outlet pipe 23 is connected to the smoke control cabinet 21, and the other end is connected to the external atmosphere; the smoke control cabinet 21 is used to provide power to transport the smoke in the processing space from the air suction pipe 22 to the air outlet pipe 23, discharge the gas into the external atmosphere, and discharge the smoke out of the processing space in time. The external atmosphere referred to here refers to the area connected to the external atmosphere, which can be a waste gas discharge area for centralized treatment, or it can be directly discharged after further purification treatment, which can be understood by those skilled in the art.

[0055] The robot component 30 and the laser component 40 are arranged in the processing space; the robot component 30 has an operating end, and the laser component 40 is fixed to the operating end, and the laser component 40 is used to laser cut the bumper 90;

[0056] The bumper positioning component 50 is disposed in the processing space, and the bumper positioning component 50 is used to position the bumper 90 at the punching station.

[0057] Based on the above structure, the automobile bumper laser drilling system of this embodiment positions the bumper 90 at the drilling station by setting a bumper positioning component 50, and drives the laser component 40 to laser cut the bumper 90 according to the preset cutting hole position through the robot component 30; an independent processing space is formed by setting a room component 10, and the processing space is connected to the external atmosphere through the smoke and dust removal component 20, and the smoke and dust control cabinet 21 provides power to transport the smoke and dust in the processing space to the outside through the suction pipe 22 and the outlet pipe 23. The large amount of smoke and harmful gases generated during the drilling process of the bumper 90 will be further purified or guided into the atmosphere of the emission area, so that the smoke and dust will be discharged from the processing space in time, so that the processing space remains smoke and dust-free, reducing the direct contact of harmful substances with the body and products, and avoiding the smoke and dust generated during the bumper drilling process to have adverse effects on workers' health, production equipment and the environment.

[0058] Specifically, the housing component 10 of this embodiment measures 3.2 meters in length, 3.2 meters in width, and 2.6 meters in height. The frame structure is assembled from a number of profiles and panels, providing a certain level of support and protection. The frame structure comprises a top plate 11 disposed at the top; a bottom plate 12 formed on the ground, which in some embodiments is also the floor; left and right side plates 13 disposed on the left and right sides; and a front plate 15 and a back plate 16 disposed at the front and rear ends.

[0059] The top plate 11 is provided with a plurality of ventilation holes 111. The number and shape of the ventilation holes 111 correspond to the ends of the suction pipe 22, allowing the ends of the suction pipe 22 to penetrate into the processing space through the ventilation holes 111, connecting the interior of the processing space with the outside world. In some embodiments, the suction pipe comprises a main pipe and a branch pipe. The main pipe is connected to the branch pipe via a multi-way pipe head. The main pipe is connected to the smoke control cabinet 21. The respective pipe openings of the branch pipe are connected to the corresponding ventilation holes 111 on the top plate 11.

[0060] The number of ventilation holes 111 in this embodiment is 3, and the three ventilation holes 111 are linearly arrayed directly above the punching station. This arrangement is conducive to the suction of smoke and dust during the processing; technical personnel in this field will make adaptive adjustments based on actual needs, and set the ventilation holes 111 in a rectangular array or a circular array, or in a manner that the holes are gradually thinned outward from the punching station.

[0061] The housing 10 also includes a rolling shutter door 151, a rolling shutter door control button 152, a laser protection plate 131, and a safety door 161.

[0062] Several laser protection panels 131 are provided on the left and right panels; the laser protection panels 131 effectively block harmful laser radiation, preventing injury or damage. A safety door 161 is provided on the back panel 16. The safety door 161 is normally closed, allowing operators to pass through.

[0063] The room body component 10 of this embodiment also includes a first grating 153 and a second grating 121; the first grating 153 is set on the front plate 15, and the first grating 153 is used to perform safety monitoring on the front side of the processing space; the second grating 121 is set on the bottom plate 12, and the second grating 121 is used to perform safety monitoring on the bottom side of the processing space.

[0064] The smoke control cabinet 21 is equipped with a filter box and a dust collection box. The dust collection box is located below the filter box in the direction of gravity. The filter box is provided with an air inlet and an air outlet. The air inlet is connected to the air suction pipe 22, and the air outlet is connected to the air outlet pipe 23. The bottom of the filter box is provided with a dust outlet.

[0065] The dust box is provided with a receiving port at the top, which is connected to the dust outlet. The filter box is provided with a filter assembly, a turbo blower, and a dust cleaning assembly. The filter assembly includes a plurality of filter cartridges, which are arranged and fixed between the air inlet and the air outlet. The turbo blower is used to supply air to the filter assembly. The dust cleaning assembly is used to scrape dust adsorbed on the surface of the filter cartridges to the dust outlet. The smoke control cabinet 21 is provided with an automatic alarm, which is used to record the usage time of the filter assembly and issue an alarm when the recorded time reaches a preset value.

[0066] The robot assembly 30 of this embodiment includes a first robotic arm 31 and a second robotic arm 32. The first robotic arm 31 and the second robotic arm 32 are positioned near the punching station and are both six-axis vertical multi-jointed robotic arms. One end of the first robotic arm 31 is fixed to the base plate 12 via a ground spike, and the other end forms a first operating end 311. The second robotic arm 32 is fixed to the base plate 12 via a ground spike at one end, and the other end forms a second operating end 321. The dual robotic arms work together to improve punching efficiency.

[0067] The laser assembly 40 includes a first laser and a second laser. The first laser is fixed to the first operating end 311, and the second laser is fixed to the second operating end 321. Both the first and second lasers are CO2 lasers, each having a metal tube that encapsulates the gas medium generated by the laser. The laser assembly 40 can be controlled by an external laser control cabinet 70.

[0068] The metal tube structure used in this embodiment has the following advantages over the traditional glass tube structure: 1. The metal tube has a service life of more than three years. The gas inside can be recharged and used again after it is used up, making it reusable, while the glass tube generally needs to be replaced every six months or so and is disposable and cannot be reused. 2. The metal tube is more stable than the glass tube. The performance of the glass tube is unstable, and the power supply is prone to aging after long-term operation, which poses a safety hazard and greatly interferes with the control system. For example, improper operation can easily burn out the motherboard, and it is more susceptible to voltage damage and damage to its normal function. 3. The CO2 metal tube has a fine light spot, high precision, and little thermal impact, making it suitable for fine processing. The glass tube has a coarse light spot, poor precision, unstable light output, a large heat diffusion area, and obvious melting and blackening of the cut edge. 4. The CO2 metal tube can operate stably and without trouble for a long time. The glass tube will have unstable or no light output if the continuous processing time is too long or the water temperature is not within a constant range. Continuous operation has a significant impact on product quality. 5. Although the traditional glass tube sealed CO2 laser is relatively cheap, it has a high failure rate, short life, large size, poor beam mode (rough cutting seam), slow light response speed, and the same power laser has different processing effects on different materials. 6. In addition, for installation on a robotic arm, the glass tube laser is fragile, not vibration-proof, and has a relatively long volume and length, making it suitable for fixed refractive structure machines. 7. The advantages of metal tube lasers when installed on a robot are: small size, vibration-proof, firm installation, can be directly connected to the cutting head to output laser, strong sealing, not easily contaminated by internal dust, and stable and fine light output.
