VC temperature equalizing plate semi-automatic spot welder is a semi-automatic spot welder for mobile phone VC temperature equalizing plate spot welding tailored to customer needs. It has high strength after welding, smooth appearance, high yield, and welding efficiency. Fast, low equipment investment costs.

I. Customer background and pain points

SZZD Electronics (Jiangsu) Co., Ltd., affiliated to TD Group, ranks among the top 100 in the IT industry in the world. The group company covers China, the United States, Japan, Europe, Scotland, Southeast Asia and other places, and holds world-class leadership in a number of electronic products. , Including providing overall solutions for power management, video displays, industrial automation, network communications products, and products related to renewable energy; Huawei, Samsung, Xiaomi, and OV and other manufacturers introduced temperature equalization boards in 5G smartphones, and SZZD took over They have a large number of uniform temperature plate orders, the problems encountered during trial production are:

• The welding quality is not up to standard, and the yield after laser and ultrasonic testing is very low, less than 75%;

• The appearance is unqualified, the appearance is piled up after welding with TIG, and the customer cannot accept it;

• The efficiency is too low to meet the demand for production capacity. On-site testing of manual TIG welding, the welding time of a single piece exceeds 10 seconds;

• The production cost is too high, the laser workstation investment exceeds one million, and the operation and maintenance costs exceed 20% of the budget;

The above five customers are very distressed and have not been able to find a solution.

Second, customers have high requirements for equipment

SZZD Electronics found us online on March 16, 2018, discussed with our sales engineers and wanted to customize the special welding equipment with the following requirements:

1.Ensure welding quality, yield rate is above 85%;

2. Appearance is qualified, no stack height

3. Efficiency must be improved;

4. Input costs and operating costs are within the budget range;

According to the requirements of customers, the original spot welding equipment could not be realized at all, what should I do?

Third, according to customer needs, research and develop custom VC temperature equalizing plate nozzle semi-automatic spot welder

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, and configuration, list key risk points, and make one by one The solution, the basic direction and technical details are determined as follows:

1. Workpiece proofing test : Anjia Welding Technician made a simple fixture for proofing at the fastest speed, used our existing servo flash butt welding machine to proof test, and performed small batch verification to basically determine the welding parameters;

2. Equipment selection : The R & D engineers and welding technicians communicated together and calculated the selection power according to customer requirements. Finally, they were confirmed as ADB-120 IF inverter DC welding machine;

”,如ABB的大功率二级管,Semikron的IGBT逆变模块等; 3. Stability of equipment : Our intermediate frequency inverter DC welding machine control system with independent intellectual property rights, all core components are " imported configuration ", such as ABB's high-power diodes, Semikron's IGBT inverter modules, etc .;

4. Equipment advantages :

1) Improved yield rate : our selected ADB-120 IF inverter DC welding special machine, full wave rectification, DC output, high peak value and fast climbing, are currently more advanced power sources, supplemented by special welding technology, which guarantees Welding strength, not to cause the temperature-melting plate to melt and break the vacuum, which greatly improves the yield rate, and the pass rate reaches more than 99.5%;

2) The appearance of the product after welding is assured : because the servo pressurization and resistance heating are used, there is no external heat source output, the material itself generates heat to reach a plastic state, and a nugget is formed outside the high temperature and high pressure. The surface of the workpiece is smooth and smooth;

3) Improve welding efficiency : adopting XY servo action, combined with multi-station fixture, greatly improves the beat. Through manual placement and automatic movement welding, the welding time is greatly shortened, and the beat is controlled within 2.5 seconds of a single piece. Improved welding efficiency by 75%;

4) Reduced the cost of investment equipment : This equipment is a semi-automatic special machine, the cost is only 20% of the laser equipment; reduced operating costs, ordinary workers can be employed after simple training, and the welding process without the addition of wire and solder, compared with the original Reduced production costs by 40%;

Anjia discussed the above technical solutions and details with SZZD Electronics. After the two parties finally reached an agreement, they signed a "Technical Agreement" as the standard for equipment R & D, design, manufacturing, and acceptance, because our thoughtfulness touched the customer, and in 2018 An order agreement was reached with Suzhou FLX on May 10.

Fourth, fast design, on-time delivery, professional after-sales, and get praise from customers!

After confirming the equipment technical agreement and signing the contract, Anjia's project manager held the production project launch meeting as soon as possible, and confirmed the mechanical design, electrical design, machining, outsourced parts, assembly, joint adjustment time nodes and customers to come to the factory for pre-acceptance. , Rectification, general inspection and delivery time, and orderly issue work orders of each department through the ERP system, supervise and follow up the work process of each department.

After 30 working days in a flash, the SZZD electronic customized VC temperature equalizing plate nozzle semi-automatic spot welder was completed after aging test. Our professional after-sales engineer went through 2 days of installation and commissioning and technical, operation and maintenance training at the customer site. Equipment Has been put into production normally and all meet the customer's acceptance standards.

Suzhou ZD Electronics is very satisfied with the actual production and welding results of the VC isothermal plate nozzle welding machine, helping them improve the yield, improve the welding efficiency, save labor, and reduce investment costs, and also give us high recognition and praise!
