Description

Technical Field

[0001] The present invention relates to the technical field of laser etching of vehicle lamp moulds, and in particular to intelligent laser etching and function-integrated processing equipment for vehicle lamp moulds. Background Art

[0002] The laser etching and functional integration processing equipment for automotive lamp molds is an advanced manufacturing equipment that combines high-precision laser etching technology, intelligent control modules and multi-process integration capabilities. It is designed for efficient and precise processing and functional surface treatment of automotive lamp molds. It uses femtosecond laser or ultrafast laser technology, combined with a galvanometer system, to achieve precision etching with sub-micron resolution, meeting the requirements of automotive lamp molds for fine textures and structures.

[0003] In the laser etching and functional integration processing equipment for automotive lights, the laser converts electrical energy or light energy into laser light with excellent monochromaticity, directionality and coherence through the principle of stimulated radiation. The deflection direction and focusing position of the laser beam are then controlled by a high-speed vibrating galvanometer to achieve fast and precise two-dimensional scanning etching. Finally, the laser refracted by the galvanometer is focused on the working plane through a field mirror for etching. Since there is a certain distance between the galvanometer and the etched mold, and the galvanometer swings at an extremely fast rate during operation, any slight angular deviation of the galvanometer mirror will cause a significant position shift of the laser spot on the working plane.

[0004] When processing large automotive lamp molds, due to the large mold area, the galvanometer requires a larger scanning angle and a longer scanning stroke during the processing process. This will increase the load on the galvanometer rotor and significantly increase the moment of inertia, making it difficult to quickly respond to high-frequency commands. Ultimately, as the working time accumulates, swing errors will occur, which will lead to defects in the etching of the automotive lamp mold. Even due to excessive swing amplitude, the internal galvanometer system will be burned and damaged. Most existing technologies predict errors through software system calculations. However, due to the extremely high swing rate of the galvanometer during etching, it cannot respond quickly to stop the laser etching when swing errors occur. In addition, long-term driving of the galvanometer motor will cause copper loss and increase the coil temperature, which will cause resistance changes, reduce the driving torque and further cause dynamic errors. This error will gradually accumulate and eventually lead to excessive swing errors, causing the laser to etch into areas of the mold that do not need to be etched, resulting in damage to the automotive lamp mold. Although the galvanometer system in the existing technology is equipped with a cooling fan to dissipate the heat generated by the galvanometer motor, the cooling fan will cause airflow instability within the galvanometer system when in operation, resulting in increased resistance when the galvanometer swings, which will affect the stability of the galvanometer swing.

[0005] Therefore, an intelligent laser etching and function integration processing equipment for car lamp molds is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent laser etching and functional integrated processing equipment for automotive lamp molds, which solves the problem that the galvanometer cannot quickly physically cut off the laser when a swing error occurs, causing damage to the automotive lamp mold, and the cooling fan in the galvanometer system is prone to unstable airflow, which increases the galvanometer swing resistance and affects the swing stability. By setting a protective component, when a dynamic error occurs in the galvanometer and causes a large laser offset angle, the barrier ring will instantly pop out to surround the galvanometer to prevent the laser from further damaging the mold, and can achieve annular heat dissipation of the motor, reducing the resistance of the unstable airflow to the galvanometer.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] Disclosed is an intelligent laser etching and functional integration processing device for a vehicle lamp mold, comprising a workbench, a movable frame arranged on the workbench, a laser mounted on the movable frame, a box fixedly connected to the laser, two sets of motors mounted in the box, a galvanometer fixedly connected to the output shaft of the motor, and a field mirror arranged at the bottom of the box. The device also comprises a trigger assembly arranged on the field mirror, a warning assembly arranged on the trigger assembly, a heat dissipation assembly arranged on the galvanometer, and a protection assembly arranged on the galvanometer. When the galvanometer has a swing error, the trigger assembly triggers the protection assembly to surround and block the galvanometer, and at the same time triggers the warning assembly to fall. The heat dissipation assembly surrounds the motor and accelerates the heat dissipation efficiency when the warning assembly falls. Under normal working conditions, the airflow generated by the heat dissipation assembly flows along the reflecting surface of the galvanometer toward the end of the motor, which can effectively reduce the resistance of the airflow to the galvanometer.

[0009] Preferably, the trigger assembly includes a mounting ring fixedly connected to the field lens at the bottom of the box body, multiple groups of swing rods rotatably connected to the top plane of the mounting ring, a hook fixedly connected to the swing rod, an elastic member installed between the end of the swing rod and the box body, and a nylon rope ring hooked between the multiple groups of swing rods; when the laser is irradiated on the nylon rope ring, the nylon rope ring will be instantly melted, and at this time, the end of the swing rod will be instantly pulled back by the elastic member to abut against the bottom plane of the box body.

[0010] Preferably, the warning assembly includes a ring groove provided at the bottom of the mounting ring, a warning ring slidably connected in the ring groove, a connecting rod fixedly connected to the warning ring, a snap ring fixedly connected to the top of the connecting rod, a ventilation channel provided in the connecting rod, a ventilation hole provided below the ventilation channel, and a limiting piece provided at the bottom of the mounting ring; the connecting rod passes through the mounting ring and is slidably connected thereto; after the nylon rope is melted, the swing rod will drive the limiting piece to release the limit on the warning assembly, and the warning ring will fall under the action of gravity.

[0011] Preferably, the ventilation channel is located in the upper half of the connecting rod, and the lower half of the connecting rod is solid. When the warning ring is in the ring groove, the ventilation hole is located above the mounting ring; when the warning assembly is triggered, the warning ring will fall under the action of gravity, and air will be able to enter the box body along the ventilation hole and the ventilation channel.

[0012] Preferably, the limiting member includes a limiting groove provided on the outer surface of the warning ring, an insert block slidably connected to the bottom of the mounting ring, an elastic member 2 installed between the insert block and the mounting ring, and a push rod slidably connected to the bottom of the box body; the bottom of the push rod is inclined; when the nylon rope ring is melted, the swing rod pulled back by the elastic member in an instant will press the push rod downward to push the insert block to overcome the elastic force of the elastic member 2 and move to the left to disengage from the limiting groove. At this time, the warning ring will fall under the action of gravity.

[0013] Preferably, the heat dissipation assembly includes a heat dissipation seat fixedly connected to the side wall and the top of the box body, a heat dissipation fan installed on the heat dissipation seat, exhaust holes arranged in an array on the heat dissipation seat, an enclosing ring fixedly connected to the heat dissipation seat, and multiple groups of guide plates fixedly connected to the inner side of the enclosing ring; the motor is fixedly connected to the heat dissipation seat; when the heat dissipation fan is working, the airflow will flow along the refractive surface of the galvanometer into the enclosing ring.

[0014] Preferably, the guide plate is located on both sides of the exhaust hole and is fixedly connected to the heat sink. The guide plate and the exhaust hole form a channel for airflow to pass through, and a gap is left between the guide plate and the motor so that the guide plate does not contact the motor. The guide plate can make the airflow entering the surrounding ring more stable and uniform, and less disturb the airflow.

[0015] Preferably, the protection component includes four groups of sliding rods slidably connected to the enclosing ring, a blocking ring fixedly connected to the sliding rod, three elastic parts sleeved on the sliding rod, and a control part arranged next to the blocking ring; when the component is triggered, the blocking ring will be pushed by the elastic part three and pop out instantly to surround the galvanometer, and the laser will be blocked at this time.

[0016] Preferably, the control component includes a bracket fixedly connected to the inner wall of the box body, an electric push rod installed on the bracket, a jack opened on the blocking ring, a conductive block 1 fixedly connected to the end of the swing rod, a conductive block 2 fixedly connected to the box body, and a battery fixedly connected to the box body; the conductive block 1, the electric push rod, the battery and the conductive block 2 are electrically connected; when the nylon rope ring is melted, the blocking ring will be instantly bounced open by the thrust of the elastic member 3 to surround the galvanometer.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the galvanometer of the present invention encounters a dynamic error, the galvanometer will cause the refraction angle of the laser to shift, thereby causing the laser to illuminate the circumferential range of the galvanometer. At this time, the laser will pass through the nylon rope ring and melt the nylon rope ring, and the swing rod will be released from the restraint and pulled back by the elastic member in an instant to abut against the bottom plane of the box body. At this time, the conductive block 1 at the end of the swing rod contacts the conductive block 2 at the bottom of the box body, thereby energizing the electric push rod and quickly retracting it from the socket to release the limit on the blocking ring. Then, the blocking ring is pushed open by the elastic member 3 and instantly bounces open to surround the galvanometer, blocking the laser irradiation and preventing the laser from damaging the headlight mold and internal electrical components.

[0019] 2. In the present invention, after the nylon rope ring is melted, the swing rod that is pulled back by the elastic member in an instant will also press the push rod to move downward, and then the inclined surface at the bottom of the push rod gradually pushes the plug to overcome the elastic force of the elastic member 2 and move to the left to leave the limit groove. At this time, the warning ring will fall under the action of gravity, and the vent hole is below the mounting ring. Air can enter the box body along the vent hole and the ventilation channel, and the heat dissipation fan can draw outside air through the motor to accelerate the heat dissipation efficiency of the motor.

[0020] 3. In the present invention, when the nylon rope ring is not melted, the warning ring will be in the ring groove and the vent hole will be above the mounting ring. At this time, air cannot enter the box body from the connecting rod, which can prevent the smoke from the etching process from entering the box body from the ventilation channel. When the heat dissipation fan is working normally, the air flow will flow along the refractive surface of the galvanometer into the surrounding ring, and will be evenly separated by the guide plate and discharged from the exhaust hole, which can effectively reduce the resistance of the air flow to the galvanometer, prevent the unstable air flow from causing the increase of resistance when the galvanometer swings, and affect the stability of the galvanometer swing.

[0040] As an embodiment of the present invention, refer to Figure 8The guide vanes 45 are located on both sides of the exhaust holes 43 and are fixedly connected to the heat sink 41. The guide vanes 45 and the exhaust holes 43 form a channel for airflow to pass through, and a gap is left between the guide vanes 45 and the motor 14 so that they do not contact the motor 14. The guide vanes 45 can make the airflow entering the surrounding ring 44 more stable and uniform, reducing the generation of disturbed airflow. At the same time, when the heat dissipation fan 42 is working, it can guide the airflow around the motor 14 to quickly pass through the exhaust holes 43, thereby improving the heat dissipation efficiency.

[0041] As an embodiment of the present invention, refer to Figure 9 and Figure 10 The protection component 5 includes four sets of sliding rods 51 slidably connected to the surrounding ring 44, a blocking ring 52 fixedly connected to the sliding rod 51, an elastic member 53 sleeved on the sliding rod 51, and a control member 54 arranged next to the blocking ring 52; the blocking ring 52 is made of a rough metal material. When the component is triggered, the blocking ring 52 will be pushed by the elastic member 53 to instantly pop out and surround the galvanometer 15, and the laser will be blocked at this time.

[0042] As an embodiment of the present invention, refer to Figure 9 and Figure 10 The control component 54 includes a bracket 541 fixedly connected to the inner wall of the box body 13, an electric push rod 542 installed on the bracket 541, a socket 543 opened on the blocking ring 52, a conductive block 1 544 fixedly connected to the end of the swing rod 22, a conductive block 2 545 fixedly connected to the box body 13, and a battery 546 fixedly connected to the box body 13; the conductive block 1 544, the electric push rod 542, the battery 546 and the conductive block 2 545 are electrically connected; when the nylon rope ring 25 is melted, the swing rod 22 will be instantly pulled back by the elastic member 2 373, and the conductive block 1 544 at the end of the pulled-back swing rod 22 will contact the conductive block 2 545 at the bottom of the box body 13, thereby energizing the electric push rod 542 to quickly retract and disengage from the socket 543 to release the limit on the blocking ring 52. At this time, the blocking ring 52 will be instantly bounced open by the push of the elastic member 3 53 to surround the galvanometer 15.

[0043] Working principle: After placing the headlight mold on the workbench 1, the moving frame 11 will drive the laser 12 to move above the headlight mold in coordination with the galvanometer 15 to perform etching on the headlight mold. During this process, the motor 14 will continuously drive the galvanometer 15 to swing so that the laser passes through the field lens 16 to scan and etch the headlight mold. When the galvanometer 15 encounters a dynamic error, the galvanometer 15 will offset the refraction angle of the laser, thereby causing the laser to illuminate the circumference of the field lens 16. At this time, the laser will pass through the nylon rope ring 25 and melt the nylon rope ring 25. The swing rod 22 will be released from its restraint and instantly pulled back by the elastic member 24 to abut against the bottom plane of the box body 13. At this time, the conductive block 544 at the end of the swing rod 22 The second conductive block 545 at the bottom of the box body 13 will come into contact with the second conductive block 545, thereby energizing the electric push rod 542 and quickly retracting it from the socket 543 to release the limit on the blocking ring 52. The blocking ring 52 will then be instantly pushed open by the push force of the elastic member 3 53 to surround the galvanometer 15, blocking the laser irradiation and preventing the laser from damaging the mold and internal electrical components. At the same time, after the nylon rope ring 25 melts, the swing rod 22 instantly pulled back by the elastic member 1 24 will also press the push rod 374 downward. The inclined surface at the bottom of the push rod 374 will gradually push the plug block 372 to overcome the elastic force of the second elastic member 373 and move to the left to separate from the limit slot 371. At this time, the warning ring 32 falls under the action of gravity, notifying the operator of a machine failure.

[0044] When the motor 14 has been working for too long and generates heat, the dynamic error of the galvanometer 15 causes the nylon rope ring 25 to melt and the warning ring 32 to fall. At this time, the vent hole 36 is below the mounting ring 21, and air will be able to enter the box body 13 along the vent hole 36 and the ventilation channel 35. The cooling fan 42 can draw outside air through the motor 14 to accelerate the heat dissipation efficiency of the motor 14. When the nylon rope ring 25 is not melted, the warning ring 32 is in the ring groove 31, and the vent hole 36 is also above the mounting ring 21. At this time, air cannot enter the box body 13 from the connecting rod 33, which can prevent the smoke generated during the etching process from entering the box body 13 from the ventilation channel 35 and causing pollution. When the cooling fan 42 is working normally, the airflow will flow along the refractive surface of the galvanometer 15 into the surrounding ring 44, and be evenly separated by the guide plate 45 and discharged from the exhaust hole 43, which can effectively reduce the resistance of the airflow to the galvanometer 15.
