KD-V300-II-JS second-generation formic acid furnace is optimized and upgraded on the basis of first-generation formic acid furnace to achieve "modularization", that is, the equipment can be transformed and upgraded from "three cabins" to "four cabins" in a very short cycle. Design purpose: to keep up with the development trend of the industry and realize the leap of equipment to modularization. Background: Although the traditional three-cabin and four-cabin welding furnaces have their own advantages, it is difficult to realize the transformation from three-cabin to four-cabin, and although there are many similarities between the two, it is difficult to realize the mutual conversion.The PLC automatic control logic is optimized with the thinking of industrial design of intelligent combination of human-computer interaction, and the combined control scheme of host computer + PLC is used for equipment control. On the one hand, it makes the equipment easy to operate, and on the other hand, it improves production efficiency. According to the welding process selected by the customer, the PLC automatically generates the corresponding control strategy and executes it, ensuring the continuity and stability of production. The emergency stop button and the industrial computer are installed at a reasonable height, and the panel is also equipped with an adjustable device mechanism, which is designed to meet the concept of safety and ergonomics, and reflects the principle of human-machine friendliness. Optimize the product structure design, and adopt the high-end online structure in the whole machine equipment. Our company's vacuum welding machine equipment can be connected to the upstream placement machine and the downstream cleaning machine and other equipment used in chip packaging, and adopts a three-stage structure distribution, which is a preheating cabin, a welding cabin, and a cooling cabin, and the welding process of the three cabins working at the same time on the assembly line effectively improves the welding efficiency of the chip. The online equipment is matched with self-circulating conveying trays, which reduces manual intervention and pallet stacking, and improves the automation degree of the production line. In addition, the equipment is "modular" at both the mechanical and electrical levels, allowing for the transformation of three to four cabins in a short period of time according to customer requirements.The second generation of three-stage automatic online vacuum welding formic acid furnace (KD-V300-II-JS) ensures the overall coordination and unity in terms of appearance, color matching and material, and adopts environmentally friendly materials based on the principle of green conservation, so that the overall product style is beautiful and generous, and the product market recognition is improved;This product has a great effect on breaking the blockade of foreign technology and establishing national self-confidence. In terms of modularity, it has reached or even surpassed the international first-line brands.Safety: The device has dual front and rear panic buttons. Follow the principle of "power on and water". The waterway is provided with a liquid receiving tank and a water leakage detection element. The circuit and compressed air are equipped with safety circuits to ensure the personal safety of the operators under special working conditions such as power failure and gas failure. Health: Although the equipment involves the application of formic acid gas. However, the top of the main engine is equipped with formic acid alarm and large-diameter vents, and the equipment is provided with exhaust hoods at the entrance and exit of the cabin, and actively exhausts the air through the vacuum generator. This ensures that operators can detect and deal with harmful gas leaks as soon as possible. Ease of use: The equipment has a concise and easy-to-understand human-computer interaction page, and all instruments are ergonomically installed and easy for personnel to operate.
