The automatic dip coating line for battery copper bars is an automated production equipment specifically designed for copper bars used in battery packs such as new energy vehicle batteries and energy storage batteries. Its core function is to apply insulation and anti-corrosion coatings on the surface of copper bars. Through full-process automated control, it ensures the uniformity and consistency of the coating, meeting the high reliability requirements of the battery industry.
Automatic Feeding: Battery copper bars to be processed are automatically fed into the production line at preset intervals via robotic arms or conveyor belts. The line is adaptable to copper bars of different lengths and widths, eliminating manual intervention and improving feeding efficiency.
Pretreatment (Cleaning + Drying):
Degreasing and Cleaning: Copper bars are immersed in a specialized cleaning solution to remove surface oil, dust, and oxide layers, laying a foundation for coating adhesion.
Deionized Water Rinsing: Residual cleaning solution is thoroughly rinsed off to avoid affecting coating performance.
Hot Air Drying: Circulating hot air at 80-120℃ dries the copper bars, ensuring no moisture remains on the surface.
Precision Dip Coating: Dried copper bars are immersed in specialized coating solutions (such as insulating paint and anti-corrosion coatings) at a controlled speed of 5-20mm/s. Coating thickness (0.05-0.3mm) is precisely controlled by adjusting immersion time, lifting speed, and solution viscosity, adapting to different battery insulation requirements.
Curing Treatment: Coated copper bars enter a curing oven for segmented temperature-controlled curing at 120-180℃ (holding time: 20-60 minutes). This ensures full cross-linking of the coating, enhancing its hardness, wear resistance, and insulation performance. The oven is equipped with a temperature monitoring system to guarantee curing stability.
Cooling + Automatic Unloading:
Natural cooling or forced air cooling to room temperature, preventing copper bar deformation due to temperature differences.
After passing quality inspection, copper bars are automatically collected by the unloading mechanism, completing the full production process.
Fully automated operation reduces manual intervention and human errors.
Precisely controllable coating thickness with excellent uniformity, meeting the precision insulation requirements of battery copper bars.
High process integration covers all links from feeding, pretreatment, dip coating, curing to unloading, ensuring high production efficiency.
Strong flexibility to adapt to copper bars of various specifications, with customizable process parameters according to customer needs.
