汽车连接件母排 PVC 自动浸涂线是专为汽车电气系统核心部件 —— 连接件母排设计的自动化涂层加工设备，核心功能是为母排表面均匀覆盖 PVC 绝缘涂层，保障其在汽车复杂工况下的绝缘性能与耐老化性。设备由上料输送系统、预处理模块（脱脂、除锈、磷化，去除母排表面油污与杂质）、PVC 浸涂槽、固化烘干炉、冷却模块及下料系统构成，全程实现自动化连续作业。
工作时，汽车连接件母排经上料系统固定在工装架上，先进入预处理模块完成表面清洁，确保涂层附着力；随后由机械臂或输送链精准送入 PVC 浸涂槽，通过控制浸涂速度、停留时间（通常 3-10 秒，根据膜厚需求调整），使母排表面形成均匀的 PVC 涂层；浸涂后多余涂料经沥干装置回收，再进入固化烘干炉（温度 160-200℃，时长 15-30 分钟），实现 PVC 涂层熔融固化；最后经冷却模块降温至室温，完成下料与质检。
设备配备智能控制系统，可预设浸涂参数（如温度、速度、膜厚），支持多规格母排柔性切换，同时 PVC 涂料回收系统减少物料浪费，固化炉采用热风循环设计保障温度均匀性。其加工精度高（膜厚误差 ±0.02mm）、自动化程度高（人工仅需上料下料），能满足汽车行业对连接件母排 “高绝缘、高耐温、高一致性” 的严苛要求，广泛应用于新能源汽车、传统燃油车的电气系统部件生产，适配车载电源、控制器等核心部件的母排加工。
The Automotive Connector Busbar PVC Automatic Dipping Coating Line is an automated coating processing equipment specially designed for connector busbars, the core components of automotive electrical systems. Its core function is to evenly cover the surface of busbars with a PVC insulating coating, ensuring their insulation performance and aging resistance under complex automotive working conditions. The equipment consists of a feeding and conveying system, a pretreatment module (degreasing, derusting, phosphating to remove oil and impurities from the busbar surface), a PVC dipping tank, a curing and drying oven, a cooling module, and a blanking system, realizing automatic continuous operation throughout the process.
During operation, automotive connector busbars are fixed on tooling racks by the feeding system, first entering the pretreatment module for surface cleaning to ensure coating adhesion; then, they are accurately sent into the PVC dipping tank by a robotic arm or conveyor chain. By controlling the dipping speed and residence time (usually 3-10 seconds, adjusted according to film thickness requirements), a uniform PVC coating is formed on the busbar surface; after dipping, the excess coating is recovered by a draining device, and then enters the curing and drying oven (temperature 160-200℃, duration 15-30 minutes) to realize the melting and curing of the PVC coating; finally, it is cooled to room temperature by the cooling module, and the blanking and quality inspection are completed.
The equipment is equipped with an intelligent control system that can preset dipping parameters (such as temperature, speed, film thickness) and support flexible switching of busbars of multiple specifications. At the same time, the PVC coating recovery system reduces material waste, and the curing oven adopts a hot air circulation design to ensure temperature uniformity. It has high processing precision (film thickness error ±0.02mm) and high automation (manual work only requires feeding and blanking), which can meet the strict requirements of the automotive industry for connector busbars of "high insulation, high temperature resistance, and high consistency". It is widely used in the production of electrical system components for new energy vehicles and traditional fuel vehicles, adapting to the busbar processing of core components such as on-board power supplies and controllers.
