Compressor shell bracket four-position projection welding machine is a four-position turntable type special projection welder tailored to Suzhou Anjia tailored to customer needs. It has high welding efficiency, high yield, and high welding efficiency. Does not rust after the characteristics. The advantages are as follows:

I. Customer background and pain points

SZYK Technology Electronics Co., Ltd., headquartered in Taiwan, mainly produces and processes precision molds, computer network connectors, optoelectronic connectors, and communication connectors. The products are sold to North America, Southeast Asia and other places. The sheet metal division is mainly used for Samsung and Hitachi compressors. For stamping parts such as shells and brackets, the problems encountered in the trial production of newly connected shell projects are:

• The welding quality is not up to standard, and two bumps are often unbalanced, resulting in only two points being qualified;

• The appearance is unqualified, the solder joints are too oxidized to affect the appearance, and will rust after being left for a few days;

• Excessive size, the fixture cannot be checked after welding;

• The efficiency is too low to meet the demand for production capacity. On-site testing manual welding, the welding time of a single piece exceeds 12 seconds, and there are hidden safety risks;

• Cannot achieve fully automated expansion and restructuring to meet the needs of subsequent large-scale restructuring;

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

Second, customers have high requirements for equipment

SZYK Technology Company found us online on July 20, 2018, discussed with our sales engineers and wanted to customize the special welding equipment with the following requirements:

1. Ensure welding quality, and the yield rate is above 95%;

2. Appearance is qualified, no over-oxidation, no rust for several days

3. After welding must be able to pass the inspection fixture

4. Under the premise of ensuring safety, efficiency must be improved;

5. Can meet the needs of future fully automated reform.

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 development of custom compressor housing bracket four-position projection welding machine

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.According to the above requirements, we basically determined the plan, manual loading and unloading, automatic welding, four-station wheel welding, the whole station only needs 2 people to operate online, 1 person to load and unload, 1 person to control the quality, and basically realized artificial intelligence. And made the following equipment:

2. Workpiece proofing test : Anjia Welding Technician made a simple fixture for proofing at the fastest speed. We used our existing IF inverter DC welding machine for proofing test and small batch verification to basically determine the welding parameters;

3. Equipment selection : R & D engineers and welding technicians communicate together and calculate the selection power according to customer requirements. Finally, they are confirmed as ADB-320 intermediate frequency inverter DC welding machine;

”,如ABB的大功率二级管,Semikron的IGBT逆变模块等; 4. Stability of the 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 module, etc .;

5. Equipment advantages :

; 1) Improved yield rate : our choice of ADB-320 IF inverter DC welding special machine, full-wave rectification, DC output, high peak value, fast climbing, is the most advanced power supply at present, supplemented by 3D analog electrodes, which guarantees Welding strength also meets the needs of two points of equilibrium, greatly improving the yield rate, and the preliminary statistics reached a pass rate of 99.8% ;

; 2) Solve the rust situation after welding : adopt strong standard process parameters, and add water cooling channels in the electrode part to minimize the welding heat, so that the surface after welding has only slight discoloration, and there is no rust situation for a week ;

; 3) Accurate positioning to ensure the welding quality : the profiled fixture is used to position the bracket, and the shell is restrained on one side at the same time, the other side is pushed tightly, which effectively avoids the inaccurate positioning of the shell caused by the workpiece punching deviation and ensures the inspection tool after welding. Demand

4) Improve welding efficiency : the four-station turntable is used for simultaneous welding of parts, and the efficiency is increased by 80%. Fences are used all around, and only the operation station is used to open the door. The operation station is equipped with a grating and two hands to ensure the operator. Security protection

5) Reserved for future automation restructuring : one station is reserved for the four-station turntable for subsequent manipulator blanking, and the side window is reserved for fully automatic on-line action in the future.

Anjia discussed the above technical solutions and details with SZYK Technology Co., Ltd., and finally, 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 thoughtfulness touched the customer, and in 2018 An order agreement was reached with Suzhou SZYK Technology on August 12,

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.

35 working days in the past, SZYK Technology's custom-made compressor housing bracket four-station special welding machine was completed after aging test, and after 2 days of installation and commissioning, technology, operation, Maintenance training, the equipment has been put into production normally and all reached the customer's acceptance standard. Suzhou SZYK Technology Co., Ltd. is very satisfied with the actual production and welding results of the four-station special welding machine for the compressor housing support, helping them solve welding quality problems, improve welding efficiency, save labor, and give us high recognition and praise!

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.
