是专为汽车电气系统母排（铜排、铝排等）设计的自动化涂层加工设备，核心功能是通过浸塑工艺在母排表面形成均匀、耐磨的塑料涂层（常见材质为汽车母排自动浸塑线 PVC、PE 等），起到绝缘、防腐蚀、防氧化及防机械损伤的作用，保障母排在汽车高振动、多湿度的复杂工况下稳定传导电流，是汽车电气安全的关键加工设备。

该设备的典型工作流程分为六大核心环节：首先是上料定位，通过自动化输送机构（如链条、辊道）将待加工母排精准输送至预处理工位，确保母排姿态统一；其次是预处理，依次经过脱脂槽（去除表面油污）、酸洗 / 除锈槽（清除氧化层）、水洗槽（冲洗残留药剂），为后续浸塑提供洁净表面；接着是预热烘干，母排进入预热炉（温度控制在 80-120℃），去除表面水分并提升表面温度，增强塑料涂层附着力；然后是自动浸塑，预热后的母排由机械臂或输送装置匀速浸入塑料涂液槽（涂液浓度与温度精准调控），根据涂层厚度需求控制浸塑时间与提升速度，确保涂层均匀覆盖；随后是固化定型，浸塑后的母排进入固化炉（温度 150-200℃，依塑料材质调整），使表面涂液熔融、交联固化成膜；最后是冷却下料，固化后的母排经风冷或水冷降温至常温，再由输送机构送至下料区，完成整个加工流程。

其核心优势体现在三方面：一是涂层质量稳定，自动化控制浸塑参数（温度、速度、时间），涂层厚度误差可控制在 ±0.05mm 内，无漏涂、气泡、流挂等缺陷，满足汽车行业严苛的绝缘性能要求（击穿电压通常≥20kV/mm）；二是生产效率高，实现母排连续化、无人化加工，单条生产线每小时可处理 100-300 根母排，适配汽车零部件批量生产需求；三是环保与经济性优，配备涂液循环系统，未附着的涂液回收率达 95% 以上，减少原材料浪费，同时固化炉废气经活性炭吸附处理后达标排放，符合环保标准。

目前，该设备广泛应用于新能源汽车（纯电动、混合动力）及传统燃油汽车的电气系统加工，如汽车电池包母排、电机控制器母排、高压配电箱母排等关键部件的绝缘涂层处理，是汽车电气部件量产的核心设备之一。

The Automatic Dip Coating Line for Automotive Busbars is an automated coating processing equipment specially designed for busbars (copper busbars, aluminum busbars, etc.) in automotive electrical systems. Its core function is to form a uniform and wear-resistant plastic coating (common materials include PVC, PE, etc.) on the surface of busbars through the dip coating process. This coating provides insulation, corrosion resistance, oxidation resistance, and protection against mechanical damage, ensuring that busbars can stably conduct current under the complex working conditions of high vibration and high humidity in automobiles. It is a key processing equipment for automotive electrical safety.

The typical working process of this equipment consists of six core links: First, loading and positioning – the busbars to be processed are accurately transported to the pre-treatment station by an automated conveying mechanism (such as a chain or roller table) to ensure a uniform posture of the busbars. Second, pre-treatment – the busbars go through a degreasing tank (to remove surface oil stains), a pickling/rust removal tank (to eliminate oxide layers), and a water washing tank (to rinse residual chemicals) in sequence, providing a clean surface for subsequent dip coating. Third, preheating and drying – the busbars enter a preheating furnace (temperature controlled at 80-120℃) to remove surface moisture and increase surface temperature, enhancing the adhesion of the plastic coating. Fourth, automatic dip coating – the preheated busbars are immersed in a plastic coating tank (with precise control of coating concentration and temperature) at a constant speed by a robotic arm or conveying device. The dip coating time and lifting speed are controlled according to the required coating thickness to ensure uniform coating coverage. Fifth, curing and shaping – the dipped busbars enter a curing oven (temperature 150-200℃, adjusted according to the plastic material) to melt, cross-link, and cure the surface coating into a film. Finally, cooling and unloading – the cured busbars are cooled to room temperature by air cooling or water cooling, and then transported to the unloading area by the conveying mechanism, completing the entire processing process.

Its core advantages are reflected in three aspects: First, stable coating quality – the automated control of dip coating parameters (temperature, speed, time) ensures that the coating thickness error is controlled within ±0.05mm, with no defects such as missing coating, bubbles, or sagging, meeting the strict insulation performance requirements of the automotive industry (breakdown voltage is usually ≥20kV/mm). Second, high production efficiency – it realizes continuous and unmanned processing of busbars, with a single production line capable of processing 100-300 busbars per hour, adapting to the mass production needs of automotive components. Third, excellent environmental protection and economy – it is equipped with a coating circulation system, with a recovery rate of unused coating reaching over 95%, reducing raw material waste. At the same time, the waste gas from the curing oven is treated by activated carbon adsorption and discharged up to the standard, complying with environmental protection standards.

Currently, this equipment is widely used in the processing of electrical systems for new energy vehicles (pure electric, hybrid) and traditional fuel vehicles, such as the insulation coating treatment of key components like automotive battery pack busbars, motor controller busbars, and high-voltage distribution box busbars. It is one of the core equipment for the mass production of automotive electrical components.
