Description

Technical Field

[0001] This utility model relates to the technical field of observation and protection boxes for laser welding machines, and in particular to an observation and protection box for laser welding machines with a light filtering function. Background Technology

[0002] Laser welding machines are advanced welding equipment. They utilize a high-energy-density laser beam as a heat source to rapidly melt or vaporize materials, thereby achieving the welding purpose. This welding method has many significant advantages, such as extremely high welding precision, enabling precise welding of tiny parts; high welding speed, effectively improving production efficiency; and a small heat-affected zone, minimizing the impact on the surrounding area of ​​the welded material and maintaining the stability of material properties.

[0003] During the welding process of a laser welding machine, the operator usually needs to use a filter to observe the welding process. However, with long-term use of the laser welding machine, dust may accumulate on the surface of the filter due to smoke adsorption and accumulation, which will affect the operator's observation effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an observation and protection box for laser welding machines with a light filtering function.

[0005] This utility model is achieved by the following technical solution: an observation and protection box for a laser welding machine with a light filtering function, comprising a cleaning mechanism, a filtering mechanism and a main body, wherein the cleaning mechanism is located on the outer surface of the main body and the filtering mechanism is located on the side wall of the main body;

[0006] The cleaning mechanism includes a mounting bracket, a scraper is fixedly connected to the back of the mounting bracket, a movable block is fixedly connected to the top of the mounting bracket, and a lead screw is threadedly connected to the inner wall of the movable block.

[0007] Through the above technical solution, the mounting bracket is fixedly connected to a scraper. By setting a scraper on the back of the mounting bracket, the scraper contacts the surface of the filter. By setting scrapers on both the front and back sides of the filter, and setting a movable block fixedly connected to the mounting bracket, when the movable block moves, it can drive the mounting bracket and scraper to move on the surface of the filter. Thus, the front and back sides of the filter can be cleaned by the scraper, thereby keeping the observation surface clean and ensuring that the operator can clearly observe the laser welding process.

[0008] As a further improvement to the above solution, a worm gear is fixedly connected to the top end of the lead screw, a worm is engaged with the outer wall of the worm gear, and a motor is fixedly connected to the end of the worm.

[0009] Through the above technical solution, the lead screw is fixedly connected to the worm wheel, the worm wheel meshes with the worm, and the output end of the motor is fixedly connected to the worm, so that the motor can drive the worm to rotate. When the worm rotates, it can drive the worm wheel that meshes with it to rotate, thereby driving the lead screw to rotate. When the lead screw rotates, it can drive the movable block that is threaded to the outer wall to move up and down, thereby driving the scraper to clean the surface of the filter.

[0010] As a further improvement to the above solution, a sliding rod is slidably connected to the end of the mounting bracket.

[0011] Through the above technical solution, the mounting bracket is slidably connected to the slide rod. By setting the mounting bracket to slide on the outer wall of the slide rod, the slide rod can guide the movement of the mounting bracket, while limiting the range of movement of the mounting bracket, preventing it from shaking during movement, and improving the smoothness of the overall cleaning process.

[0012] As a further improvement to the above solution, the filtering mechanism includes louvers, the upper surface of which is fixedly connected to a hinge, the lower surface of which is fixedly connected to a fixed housing, and a filter screen is slidably connected inside the fixed housing.

[0013] Through the above technical solution, the louvers are fixedly connected to the hinges, and the hinges are fixedly connected to the fixed housing. By setting the louvers on the outer wall of the fixed housing, the air outlet angle of the overall equipment can be changed through the louvers. A filter screen is set to slide on the fixed housing. By setting the filter screen inside the fixed housing, the gas discharged from the equipment can be filtered through the filter screen, thereby effectively preventing dust from spreading outward during the welding process and increasing the environmental friendliness of the overall equipment. By setting the filter screen to slide on the fixed housing, the convenience of replacing the filter screen can be increased.

[0014] As a further improvement to the above solution, a protective box body is fixedly connected to the back of the fixed outer shell, and a smoke extraction fan is fixedly connected to the inner wall of the protective box body.

[0015] Through the above technical solution, a smoke extraction fan is fixedly connected inside the main body of the protective box. By setting the smoke extraction fan on the inner wall of the main body of the protective box, the smoke and dust generated during the welding process can be extracted by the smoke extraction fan, thus avoiding the accumulation of a large amount of smoke inside the equipment.

[0016] As a further improvement to the above solution, the main structure includes a protective box body, a filter lens is fixedly connected to the front end of the protective box body, and a door panel is hinged to the back of the protective box body.

[0017] Through the above technical solution, the protective box body is fixedly connected to a filter. By setting the filter at the front end of the protective box body, the observer can be protected by the filter, avoiding direct stimulation of the eyes by strong light.

[0018] As a further improvement to the above solution, a foot brake pulley is fixedly connected to the lower surface of the protective box body.

[0019] Through the above technical solution, a foot brake pulley is fixedly connected to the lower surface of the protective box body. By setting the foot brake pulley on the lower surface of the protective box body, the flexibility of the overall equipment during movement can be increased. Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a mounting bracket that securely connects a scraper. The scraper, positioned on the back of the bracket, contacts the surface of the filter. Scrapers are present on both sides of the filter. A movable block is fixedly connected to the mounting bracket; when the movable block moves, it moves the mounting bracket and scraper across the filter surface, allowing for thorough cleaning of both sides and maintaining a clean filter surface. This ensures clear observation of the laser welding process by the operator. A worm gear is fixedly connected to the output end of a motor, driving its rotation. The worm gear's rotation drives a meshing worm wheel, which in turn rotates a lead screw. This lead screw, in turn, drives a movable block threaded to the outer wall, moving it up and down, further cleaning the filter surface with the scraper. A sliding rod is connected to the mounting bracket, guiding its movement and limiting its range of motion to prevent wobbling and improve the smoothness of the cleaning process.

[0021] This utility model features a louvered fixed connection hinge, which in turn fixes the outer casing. By installing louvers on the outer wall of the fixed casing, the air outlet angle of the entire device can be changed. A filter screen is slidably connected to the fixed casing, and by installing a filter screen inside the fixed casing, the exhaust gas can be filtered to prevent dust from spreading and increase environmental friendliness. A smoke extraction fan is fixedly connected inside the protective box body, and by installing a smoke extraction fan on the inner wall of the protective box body, the smoke extraction fan can suck away smoke and dust, preventing them from accumulating inside the device.
