LG is mainly engaged in home appliances: air conditioners, microwave ovens, and is an established Korean company. 等问题，现需要采用全自动的微波炉凸焊机生产线取代现在的人工生产线。 The original projection welding machine was manually assembled and welded on and off the material, and gradually encountered problems such as too low efficiency, unstable quality, high wages, and poor management of personnel . Now it needs to use a fully automatic microwave projection welding machine production line instead Artificial production line.
According to product characteristics and past experience, after discussing with our sales engineers, we put forward the following requirements for new customized equipment:
1. Customize the entire line of equipment to realize automatic loading and unloading. 15 lines of equipment are required for one line. Fully automatic welding of the entire line is required, and only 2 people need to be online.
2. Welding and assembly of each component of products that meet the requirements of LG CAVRTY ASSY;
3. Equipment delivery time is within 50 days;
4. The workpiece realizes multi-point convex welding. After welding requirements: the size of the parts must not be out of tolerance, the appearance is flat, the strength of the welding point is uniform, and the overlap is small;
5. Beat of production line: 13S / pcs;
6. At least 12 operators need to be saved compared to the original welding line;
7. 30% more production efficiency than the original welding line.
According to the requirements of customers, conventional projection welding machines and design ideas cannot be realized at all, what should I do?
According to the customer's requirements, the company's R & D department, welding process department and sales department jointly held a new project research and development meeting to discuss the process, fixture, structure, feeding method, detection and control method, list key risk points, and The solutions were made one by one, and the basic direction and technical details were determined as follows:
1.According to the above requirements, we basically determined the plan, the whole line automatically loading and unloading, and realizing robot operation and welding of the entire line. Only 2 people need to operate online, basically realized artificial intelligence, and made the following process sequence:
2. Equipment selection and fixture customization: According to the workpieces and dimensions provided by the customer, our welding technologists and R & D engineers discuss together and select different models based on the original LG based on different product components and welding requirements. : ADR-8000, ADR-10000, ADR-12000, ADR-15000. At the same time, different welding positioning fixtures are customized according to the design of each product to ensure welding accuracy and strength and welding quality;
3. Advantages of automatic welding line:
； 1) Welding power source: Welding power source uses energy storage power source, the welding time is extremely short, the impact on the workpiece surface is small, the welding current is large, and multiple points can be welded at one time to ensure the workpiece is flat after welding ;
焊接电极， 强度好，焊接耐磨性好 ； 2) Welding electrode: using beryllium copper welding electrode, good strength and good welding wear resistance ;
； 3) Equipment stability: The equipment adopts all imported core components, and uses our independently developed control system, network bus control, fault self-diagnosis, and the use of handling robots to ensure the reliability and stability of the equipment ;
； 4). Save labor costs and solve the problem of poor staff management: The original staff standard required a production line of 14 people, and now only requires 2 people to operate, and the rest of the robots operate, saving 12 labor costs ;
，整线在原有的标准机作业上提高了40%的焊接效率 ,实现了13S/pcs的节拍 。 5) Improved production efficiency: As the equipment operates in an assembly line, artificial intelligence has been realized. The entire line has improved welding efficiency by 40% on the original standard machine operation, and achieved 13S / pcs beats . See the detailed operation arrangement of the following pipeline:
