Features of the equipment

• Rubber valve atomization pressure regulation, using imported precision pressure regulating valve, equipped with digital pressure gauge;
• The air pressure adjustment is placed in the Z-axis position, which is intuitive and can be directly adjusted. The humanized design improves the work efficiency of operators; Open the model material conveying track, using a specially designed stainless steel chain as the carrier for transportation, equipped with stainless steel wear-resistant strips to extend the track life; The track amplitude modulation adopts a synchronous belt transmission mechanism and electric width adjustment to ensure that there is no horn mouth phenomenon during long-term adjustment of the track; The overall CNC machining of the rack large plate, independent pure steel gantry frame, ensures the parallelism and perpendicularity of the track and each axis; The entrance and exit of the track are equipped with wind curtains to prevent exhaust gas leakage, and are equipped with independent exhaust gas discharge outlets to improve the workshop environment; Programming can edit any spraying trajectory, using teaching mode programming, and the spraying path main interface is intuitive and visible; Fault sound and light alarm and menu display, user-friendly design of operation interface, simple and beautiful;
• The running trajectory can be mirrored, arranged, and copied. For multiple panels, only one trajectory needs to be edited, which is fast and convenient;
• Automatically collect and display various data, output, single product working time, etc;
• If you need to wait for the product during the work process, the glue valve will automatically move to the soaking area according to the setting to prevent the glue valve port from curing and affecting the coating effect.

Scope of application

Selective spraying on both sides of the PCB (PCBA), multi-panel, and high-throughput demand for precise selective coating of components and pins

SMT precision coating machine is an automated equipment specially designed for the post protection process of electronic manufacturing industry. It is also commonly referred to as reflow soldering coating machine, PCB three proof coating machine, selective coating machine, fully automatic coating machine, UV glue coating machine, collectively known as normal coating machine in English. It is widely used in the production scenarios of three proof protection for various precision circuit boards. SMT precision coating machine is mainly used for precise coating of PCB surface after reflow soldering process, effectively solving the problems of traditional whole board spraying, such as waste of glue, inadequate shielding, and insufficient accuracy. It is an indispensable core protective equipment in modern electronic processes.

The SMT precision coating fully automatic coating machine adopts mature visual positioning and intelligent motion control system, relying on precise trajectory calculation to achieve high-precision selective coating process. SMT precision coating can accurately avoid prohibited areas such as connectors, buttons, sockets, etc., and only quantitatively coat the circuits, solder joints, and components that need protection. The coating is uniform, the boundaries are clear, there is no overflow or leakage, and it perfectly meets the high standard process requirements of precision electronic production. SMT precision coating is compatible with various protective coatings such as UV glue and three proof paint, making it versatile and suitable for diverse production needs.

As a professional PCB three proof coating machine, SMT precision coating focuses on automation, high precision, and high efficiency advantages. The entire process does not require manual intervention and automatically completes the entire process of glue supply, spraying, thickness control, and reset, greatly reducing labor costs and human errors. The whole machine is equipped with standard SMEMA docking interface, which can seamlessly connect to SMT assembly line, adapt to batch continuous production, stable and efficient production capacity, and suitable for protective processing of precision circuit boards in home appliances, automotive electronics, new energy, and industrial control.
Compared to traditional spraying equipment, this selective coating machine has a stable structure, low operating noise, low failure rate, and simple daily maintenance. With its precise coating ability, flexible process adjustment and stable operation performance, the equipment can effectively improve the moisture-proof, insulation, corrosion resistance and anti-aging performance of PCB, and extend the service life of electronic products. It is currently a cost-effective automated solution for SMT rear protection in the industry.
