The automatic dip coating line for busbars is an automated production equipment used in the electrical industry, mainly for dip coating busbars. Busbars, also known as busbar bars, are conductive components used for collecting, distributing, and transmitting electrical energy in power systems. Dip coating can provide a protective layer for busbars, enhancing their insulation performance, corrosion resistance, etc., and improving the service life and safety of busbars.
Main Components
Loading System
It is responsible for orderly transporting the busbars to be dip - coated to the starting position of the dip coating line. Usually, equipment such as conveyor belts and manipulators are used to achieve automatic loading of busbars, improving loading efficiency and accuracy.
It can be adjusted according to the size, shape, and weight of the busbars to meet the loading requirements of busbars of different specifications.
Cleaning System
Before dip coating, the busbars need to be cleaned to remove impurities such as oil stains, dust, and oxide layers on the surface to ensure a good bond between the dip - coated layer and the busbar surface.
Cleaning methods include spray cleaning and ultrasonic cleaning. Special cleaning agents are usually used as the cleaning liquid. After cleaning, a drying process is carried out to prevent moisture residue from affecting the dip coating effect.
Dip Coating Tank
The dip coating tank is the core component of the dip coating line, which contains dip coating liquid. The type of dip coating liquid depends on the usage environment and requirements of the busbars. Common ones include insulating paint and anti - corrosion paint.
The busbars are immersed in the dip coating tank through a conveying device and then lifted out after staying for a certain period of time, so that the surface of the busbars is evenly covered with a layer of dip coating liquid. The dip coating tank is usually equipped with a stirring device to ensure the uniformity of the dip coating liquid.
Drying System
After the busbars are lifted out of the dip coating tank, there will be excess dip coating liquid adhering to the surface, which needs to be drained through the drying system. The drying system is generally set above or near the dip coating tank. Through a certain inclination angle and residence time, the excess dip coating liquid flows back into the dip coating tank.
Some drying systems are also equipped with air knives and other equipment to accelerate the drying process of the dip coating liquid and improve production efficiency.
Curing System
The busbars after draining need to be cured to form a solid protective layer from the dip coating liquid. There are mainly two curing methods: heating curing and room - temperature curing.
Heating curing usually uses equipment such as ovens and tunnel furnaces. By controlling the temperature and time, the dip coating liquid undergoes a chemical reaction under a certain temperature condition to form a film. Room - temperature curing allows the dip coating liquid to dry and cure naturally in the natural environment. This method is suitable for some dip coating liquids that are sensitive to temperature.
Unloading System
The busbars after curing are output from the dip coating line through the unloading system. The unloading system can also use equipment such as conveyor belts and manipulators to transport the dip - coated busbars to the specified position for packaging or subsequent processing.
