Microwave oven fully automatic spot welding production line is a fully automatic production line for welding various parts of microwave oven shells. It is tailored according to customer requirements and realizes automatic loading and unloading. One line requires 15 energy storage projection welding equipment. The entire line is fully automatic welding. Only 2 people need to be online, which saves 12 labors for customers, improves production efficiency by 40%, and realizes full-line automatic production and artificial intelligence.
I. Customer background and pain points
Tianjin LG is mainly engaged in home appliances: air conditioners, microwave ovens, and is an established Korean company. 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 is necessary to use a fully automatic microwave projection welding machine production line to replace the current Artificial production line.
Second, customers have high requirements for equipment
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 customer requirements, conventional projection welding machines and design ideas cannot be realized at all, what should I do?
Third, according to customer needs, research and development of customized microwave oven full automatic spot welding machine production line
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, positioning method, assembly method, loading and unloading method, and configuration, and list the key risks. Points, and made solutions one by one, and determined the basic direction and technical details 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:
，焊接时间极短，对工件表面影响小，焊接电流大， 一次性可焊接多点，保证了工件焊后平整； 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;
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 our independently developed control system, network bus control, fault self-diagnosis, and the use of the handling robot 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 ;
。 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:
Anjia fully discussed the above technical solutions and details with LG. After the two parties reached an agreement, they signed a "Technical Agreement" as the standard for equipment R & D, design, manufacturing, and acceptance, because our professional technology and meticulous service moved customers, and An order agreement was reached with LG on September 15, 2018.
Fourth, fast design, on-time delivery, professional after-sales, and get praise from customers!
After confirming the equipment technical agreement and signing the contract, the 50-day delivery period was indeed very tight. Anjia's project manager immediately held the production project launch meeting and determined the mechanical design, electrical design, mechanical processing, outsourced parts, assembly, and assembly. Time nodes and customers come to the factory to pre-accept, rectify, general inspection and delivery time, and orderly issue work orders for each department through the ERP system, and supervise and follow up the work process of each department.
Fifty days passed, the LG custom microwave oven automatic spot welding machine production line was finally completed after aging tests. Our professional after-sales service has passed 15 days of installation and commissioning and technical, operation and maintenance training at the customer site. The equipment has been put into production normally. And all reached the customer's acceptance criteria.
LG is very satisfied with the actual production and welding results of the automatic spot welding machine production line for microwave oven shells, which helped them improve production efficiency, saved them 12 labors, greatly reduced downtime, and received their full affirmation and recognition!
Fifth, meet your customization requirements is the growth mission of Anjia!
The customer is our mentor. What material do you need to weld? What welding process do you need? What welding requirements? Need full-automatic, semi-automatic, or assembly line? ”。 Please do not hesitate to mention that Anjia can " research and develop " for you.
