With the continuous development of industrial technology and increasingly strict environmental requirements, traditional industrial painting assembly lines have gradually exposed many problems, such as low production efficiency, high energy consumption, and serious environmental pollution. Therefore, the transformation of industrial painting assembly lines has become an inevitable choice for many enterprises to achieve sustainable development and enhance their competitiveness.

工业涂装流水线改造策略​

Transformation strategy for industrial painting assembly line

设备升级与自动化改造​

Equipment upgrade and automation transformation

引入先进的涂装设备：采用自动化喷漆机器人、静电喷涂设备等新型涂装设备，提高喷漆效率和质量。喷漆机器人可以根据预设程序精确控制喷枪的运动轨迹和喷涂参数，实现高速、均匀的喷涂，大大提高了涂层的质量和一致性。静电喷涂设备利用静电吸附原理，使涂料粒子更均匀地附着在工件表面，提高涂料利用率，减少涂料浪费。​

Introducing advanced painting equipment: adopting new painting equipment such as automated painting robots and electrostatic spraying equipment to improve painting efficiency and quality. Spray painting robots can accurately control the motion trajectory and spraying parameters of the spray gun according to preset programs, achieving high-speed and uniform spraying, greatly improving the quality and consistency of the coating. Electrostatic spraying equipment utilizes the principle of electrostatic adsorption to ensure that coating particles adhere more evenly to the surface of the workpiece, improving coating utilization and reducing coating waste. ​

升级输送系统：优化工件的输送方式，采用自动化悬挂输送链、辊道输送线等高效输送设备，确保工件在各工序之间快速、平稳地转移。自动化悬挂输送链可以实现工件的立体运输，节省空间，同时通过合理设置链条速度和工位间距，提高生产节拍。辊道输送线则适用于平面工件的输送，具有运行平稳、输送量大的优点。​

Upgrade the conveying system: Optimize the conveying method of workpieces, adopt efficient conveying equipment such as automated hanging conveyor chains and roller conveyor lines to ensure fast and smooth transfer of workpieces between various processes. Automated hanging conveyor chains can achieve three-dimensional transportation of workpieces, save space, and improve production speed by reasonably setting chain speed and workstation spacing. Roller conveyor lines are suitable for conveying flat workpieces and have the advantages of smooth operation and large conveying capacity. ​

实现设备的智能化控制：利用工业互联网、传感器和智能控制系统，对涂装设备进行实时监控和远程操作。通过传感器采集设备的运行数据，如温度、压力、流量等，传输到智能控制系统进行分析处理，根据预设的参数自动调整设备运行状态，实现设备的智能化运行。例如，智能烘干系统可以根据工件的材质、涂层厚度等因素自动调整烘干温度和时间，确保烘干效果的同时降低能源消耗。

Realize intelligent control of equipment: use industrial Internet, sensors and intelligent control system to conduct real-time monitoring and remote operation of coating equipment. By collecting operational data from sensors, such as temperature, pressure, flow rate, etc., the data is transmitted to an intelligent control system for analysis and processing. Based on preset parameters, the device's operating status is automatically adjusted to achieve intelligent operation. For example, the intelligent drying system can automatically adjust the drying temperature and time based on factors such as the material and coating thickness of the workpiece, ensuring the drying effect while reducing energy consumption.

优化工艺流程​

Optimize the process flow

精简工序：对现有涂装工艺流程进行全面梳理，去除不必要的工序和重复操作，缩短工艺流程。例如，在一些传统涂装工艺中，可能存在多次打磨和喷漆的工序，通过改进涂料性能和涂装技术，可以减少打磨次数，甚至实现一次喷漆即可达到理想效果，从而提高生产效率。​

Simplify the process: Conduct a comprehensive review of the existing painting process, remove unnecessary procedures and repetitive operations, and shorten the process flow. For example, in some traditional painting processes, there may be multiple polishing and painting processes. By improving the coating performance and painting technology, the number of polishing times can be reduced, and even one painting can achieve the desired effect, thereby improving production efficiency. ​

合理安排工序顺序：根据工件的材质、形状和涂装要求，重新规划各工序的先后顺序，使整个涂装过程更加顺畅。例如，对于一些容易生锈的金属工件，可以先进行防锈处理，再进行底漆涂装，然后进行面漆涂装，这样可以保证涂层的附着力和防护性能。同时，合理安排各工序之间的等待时间，避免工件长时间闲置，提高生产效率。​

Reasonably arrange the sequence of processes: Based on the material, shape, and coating requirements of the workpiece, re plan the sequence of each process to make the entire coating process smoother. For example, for some metal workpieces that are prone to rusting, rust prevention treatment can be carried out first, followed by primer coating, and then topcoat coating, which can ensure the adhesion and protective performance of the coating. At the same time, reasonably arrange the waiting time between each process to avoid prolonged idle of workpieces and improve production efficiency. ​

采用一体化涂装工艺：将多个涂装工序集成在一个设备或系统中，实现一体化涂装。例如，采用前处理、喷漆、烘干一体化的涂装设备，工件在一个封闭的系统内完成多个工序的处理，减少了工件的转运次数和等待时间，提高了生产效率，同时也有利于对废气、废水等污染物的集中处理。​

Adopting integrated coating technology: integrating multiple coating processes into one equipment or system to achieve integrated coating. For example, by using a coating equipment that integrates pre-treatment, painting, and drying, workpieces can be processed in multiple processes within a closed system, reducing the number of workpiece transfers and waiting times, improving production efficiency, and also facilitating centralized treatment of pollutants such as exhaust gas and wastewater. ​

节能减排措施​

Energy saving and emission reduction measures

更换节能设备：将高能耗的烘干设备更换为节能型烘干设备，如采用红外辐射烘干、热风循环烘干等技术，提高能源利用率。红外辐射烘干设备能够直接将能量传递给工件表面，使涂层迅速升温固化，减少了热量在空气中的损耗。热风循环烘干设备通过合理设计风道和风机，使热风在烘干室内均匀循环，提高烘干效率，降低能源消耗。​

Replace energy-saving equipment: Replace high energy consuming drying equipment with energy-saving drying equipment, such as using infrared radiation drying, hot air circulation drying and other technologies, to improve energy utilization efficiency. Infrared radiation drying equipment can directly transfer energy to the surface of the workpiece, causing the coating to quickly heat up and solidify, reducing heat loss in the air. The hot air circulation drying equipment uses reasonable design of air ducts and fans to evenly circulate hot air in the drying room, improve drying efficiency, and reduce energy consumption. ​

安装能源回收装置：在涂装设备的废气排放系统中安装热回收装置，将废气中的热量回收利用，用于预热新鲜空气或加热烘干设备。例如，采用板式换热器、热管换热器等设备，将废气中的热量传递给进入涂装车间的新鲜空气，降低新风加热所需的能耗。同时，对于一些高温废气，还可以通过余热发电装置将热能转化为电能，实现能源的梯级利用。​

Installation of energy recovery device: Install a heat recovery device in the exhaust emission system of the painting equipment to recover and utilize the heat in the exhaust gas for preheating fresh air or heating drying equipment. For example, using equipment such as plate heat exchangers and heat pipe heat exchangers, the heat in the exhaust gas is transferred to the fresh air entering the painting workshop, reducing the energy consumption required for fresh air heating. At the same time, for some high-temperature exhaust gases, thermal energy can also be converted into electrical energy through waste heat power generation devices, achieving the cascading utilization of energy. ​

优化通风系统：合理设计涂装车间的通风系统，根据车间的空间大小、设备布局和生产工艺要求，确定合适的通风量和通风方式。采用局部通风与全面通风相结合的方式，对产生废气的重点区域进行局部抽风，减少通风量，降低风机能耗。同时，通过优化通风管道的设计和布局，减少通风阻力，提高通风效率。

Optimize ventilation system: Reasonably design the ventilation system of the painting workshop, determine the appropriate ventilation volume and ventilation method based on the workshop's space size, equipment layout, and production process requirements. Adopting a combination of local ventilation and comprehensive ventilation, local exhaust is carried out in key areas where exhaust gas is generated to reduce ventilation volume and fan energy consumption. Meanwhile, by optimizing the design and layout of ventilation ducts, ventilation resistance can be reduced and ventilation efficiency can be improved.
