Description

Technical Field

[0001] The present invention relates to the technical field of laser welding equipment, and in particular to a precision parts laser welding machine with a welding slag collecting mechanism. Background Art

[0002] With the increasing requirements for the manufacturing of high-precision parts such as electronic components and micro hardware parts, laser welding has been widely used in the connection processing of precision parts due to its advantages such as beautiful welds, small heat-affected zone and high welding precision. Most of the existing precision parts laser welding machines are equipped with laser emission mechanisms, focusing mechanisms and gas protection mechanisms to achieve efficient and stable welding operations.

[0003] In the actual implementation process, there are still some problems: When welding metals and alloys, welding slag, spatter, and some molten metal residue are inevitably generated. If this slag is not collected and processed in a timely manner, it will not only easily accumulate on the work surface, affecting the quality of subsequent workpiece welding, but may also cause internal contamination of the equipment, increase the workload of manual cleaning, reduce production efficiency, and even cause equipment failure or safety hazards due to high-temperature residue. Most existing laser welding machines focus on the automatic control of welding energy and welding path, and pay less attention to the effective collection of welding slag during the welding process and the dynamic cleaning of the working area. Although some equipment is equipped with smoke extraction and dust removal devices, the collection effect of metal slag and larger welding slag particles is poor. In addition, the cooling system of some existing welding equipment is often limited to internal circulation cooling, and lacks local spray cooling measures for welding points and welding slag splashing areas, resulting in overheating of the welding area or an increase in the range of welding slag splashing, which in turn affects the weld formation quality and the cleanliness of the operating environment.

The audible and visual alarm 502 is externally installed on the filter tube 501 and is electrically connected to the switch. Once triggered, it will send an alarm signal. This structure can promptly remind the operator to deal with filter blockage, prevent abnormal operation of the equipment, and ensure the long-term stable operation of the water circulation system.

[0030] Working principle: The collection and cooling mechanism 3 is mainly composed of a collection tank 301, a filter tank 309, a screw 310 and a cleaning plate 315, etc., which are installed as a whole in the top area of ​​the welding frame body 1 to efficiently collect welding slag and spatter generated during laser welding. In actual work, when precision parts need to be laser welded, the workpiece is placed at the top position of the collection tank 301. The laser welding machine slides with the top of the welding frame body 1 through the slide rail 2 and can complete the welding operation along the set trajectory. During the welding process, welding slag and metal spatter will naturally fall into the collection tank 301, avoiding the welding slag from being directly scattered into the surrounding environment and causing pollution. In order to avoid the accumulation of welding slag clogging the collection tank 301 and affecting the welding operation, the motor can be used to 305 drives the screw rod 310 to rotate, and the screw rod 310 is threadedly connected to the cleaning plate 315, so that the cleaning plate 315 slides along the inner wall of the collection tank 301, and the welding slag accumulated at the bottom of the collection tank 301 is smoothly pushed into the filter tank 309 for subsequent centralized filtering and treatment. At the same time, the cooling water stored in the collection tank 301 can form a local water film or mist on the welding area, which helps to reduce the welding heat and avoid deformation or stress concentration of the weld due to local overheating. When additional cooling or reduction of spatter is required in some special welding occasions, the transmission pump 302 installed on the inner wall of the welding frame body 1 can be started. The transmission pump 302 sucks the filtered water in the collection tank 301 through the fixed pipe 312, and transports the water to the connecting pipe 303, and then passes through the connecting pipe 3 03 is connected to the foldable hose 304, and the foldable hose 304 further guides water into the water tank 313 for storage. The water tank 313 is connected to the nozzle 314, and the stored cooling water can be atomized and sprayed to the welding area through the nozzle 314 at any time, so as to achieve secondary cooling of the welding pool and the surrounding area. At the same time, the spray can also suppress the scattering tendency of welding slag, improve the cleanliness and safety of the welding environment, reduce the subsequent cleaning workload, and thus significantly improve the welding quality and production efficiency of precision parts. A filtering mechanism 5 is provided in conjunction with it. The filtering mechanism 5 mainly includes components such as a magnetic ring 506, a magnetic block 507, a slide 503 and a filter tube 501, which are used to efficiently separate and filter the welding slag and residual liquid transmitted from the collection tank 301, and has an intelligent early warning function for the filtering status. After the welding slag and cooling water in the collection tank 301 enter the filter tank 309 under the pushing action of the cleaning plate 315, they are connected to the filter tube 501 through the three-way pipe 311 fixedly connected at the bottom, and the welding slag and residual liquid flow into the interior of the filter tube 501. The inner cavity of the filter tube 501 is installed with a filter mesh 504 component to block welding slag and particulate matter, ensuring that the filtered clean water can be extracted and recycled again by the transmission pump 302. In order to improve the convenience of disassembly and maintenance of the filtering device, a slide groove 503 is designed on the outside of the filter tube 501, and a magnetic block 507 is arranged inside the slide groove 503. The magnetic block 507 is fixed to the slidable magnetic ring 506 on the inner wall of the filter tube 501 by magnetic adsorption, which facilitates the rapid disassembly and position adjustment of the filter mesh 504 component.During long-term continuous filtering, if the filter 504 is clogged with a lot of welding slag, the weight of the welding slag attached to it will gradually increase, eventually driving the magnetic block 507 to slide downward along the inner wall of the slide 503. When the magnetic block 507 moves down to the set position, the spring return rod 508 installed at the bottom of the magnetic block 507 will trigger the push-type trigger switch 509. The push-type trigger switch 509 is electrically connected to the sound and light alarm 502 installed on the outer wall of the filter tube 501. Once the switch is triggered, the sound and light alarm 502 will immediately start and emit an sound and light alarm signal to prompt the operator to clean or replace the filter 504 in time, thereby effectively preventing waterway blockage or welding slag overflow caused by poor filtration. The filter mechanism 5 cooperates with the automatic gravity trigger device to ensure the convenience of disassembly and maintenance of the filter unit and realizes real-time automatic warning of the filtration status, greatly reducing the burden of manual inspection, improving the reliability and intelligence level of the entire set of precision parts laser welding machine, and fully meeting the continuous and stable operation requirements under high-demand welding occasions. ,
