機器人涂裝線:機器人的應用
機器人系統在涂裝生產線上的應用,正逐步改變傳統涂裝作業的模式,通過精準控制、高效運作和穩定輸出,為涂裝生產帶來多方面的提升,成為現代制造業中不可或缺的重要組成部分。
The application of robot systems in painting production lines is gradually changing the traditional painting operation mode. Through precise control, efficient operation, and stable output, it brings various improvements to painting production and has become an indispensable and important component of modern manufacturing.
在涂裝質量的提升上,機器人系統展現出顯著優勢。傳統人工涂裝易受操作人員技術水平、體力狀態影響,導致涂層厚度不均、漏涂、流掛等問題。而機器人系統通過預設的程序參數,能精確控制噴槍的移動軌跡、噴涂速度、涂料吐出量以及與工件的距離,確保每一處涂層厚度均勻一致,誤差可控制在微米級別。對于結構復雜的工件(如汽車車身的邊角、凹槽),機器人配備的多軸聯動機械臂能靈活調整姿態,讓噴槍始終保持最佳角度,保證這些難涂部位也能獲得均勻的涂層覆蓋。同時,機器人可實時監測涂料的粘度、壓力等參數,一旦出現異常立即調整,避免因材料波動影響涂裝質量,大幅提高了產品的合格率。
Robot systems have shown significant advantages in improving coating quality. Traditional manual painting is easily affected by the technical level and physical condition of operators, leading to problems such as uneven coating thickness, missed coating, and sagging. The robot system can accurately control the movement trajectory, spraying speed, coating output, and distance from the workpiece of the spray gun through preset program parameters, ensuring that the coating thickness is uniform and consistent at every location, and the error can be controlled at the micrometer level. For structurally complex workpieces (such as corners and grooves on car bodies), the multi axis linkage robotic arm equipped on the robot can flexibly adjust the posture, ensuring that the spray gun always maintains the optimal angle and ensuring uniform coating coverage for these difficult to apply areas. At the same time, the robot can monitor the viscosity, pressure and other parameters of the coating in real time, and adjust them immediately in case of any abnormalities, avoiding the impact of material fluctuations on coating quality and greatly improving the product's qualification rate.
生產效率的提高是機器人系統應用的核心價值之一。機器人能夠實現 24 小時連續作業,僅需在定期維護時短暫停機,相比人工涂裝每天 8-10 小時的工作時長,有效增加了生產時間。在節拍化生產的涂裝線上,機器人的作業速度穩定可控,每小時可完成數十甚至上百件工件的涂裝,且不會因疲勞降低效率,能嚴格匹配生產線的整體節奏,避免出現工序銜接不暢的情況。此外,機器人系統可與上料、烘干等前后工序設備聯動,形成自動化生產閉環,工件輸送、定位、涂裝、下線等流程無需人工干預,減少了中間環節的等待時間,顯著提升了整條生產線的運轉效率。
Improving production efficiency is one of the core values of robot system applications. Robots can achieve 24-hour continuous operation, only requiring brief shutdowns during regular maintenance, which effectively increases production time compared to the 8-10 hour daily working hours of manual painting. On the painting line of rhythmic production, the robot's operating speed is stable and controllable. It can complete the painting of dozens or even hundreds of workpieces per hour without reducing efficiency due to fatigue. It can strictly match the overall rhythm of the production line and avoid the situation of poor process connection. In addition, the robot system can be linked with pre - and post process equipment such as feeding and drying, forming an automated production loop. The processes of workpiece conveying, positioning, painting, and offline do not require manual intervention, reducing waiting time in intermediate links and significantly improving the operational efficiency of the entire production line.

對作業環境的改善和安全保障作用突出。涂裝過程中使用的涂料、溶劑多具有揮發性和毒性,人工涂裝時操作人員長期暴露在有害環境中,健康風險較高。機器人系統在封閉的涂裝室內作業,通過高效的廢氣收集和處理系統,將有害氣體及時排出并凈化,大幅降低了車間內的污染物濃度。同時,機器人的作業區域設置安全圍欄和感應裝置,一旦有人誤入立即停機,避免機械臂與人員發生碰撞。對于需要高溫烘干的涂裝工藝,機器人可在高溫環境下穩定工作,無需人員靠近,減少了高溫對人體的傷害,讓操作人員從惡劣的作業環境中解放出來,轉向設備監控、參數調整等更安全的工作崗位。
The role of improving the work environment and ensuring safety is prominent. The coatings and solvents used in the painting process are often volatile and toxic, and operators are exposed to harmful environments for a long time during manual painting, which poses a high health risk. The robot system operates in a closed painting room, and through an efficient exhaust gas collection and treatment system, harmful gases are promptly discharged and purified, significantly reducing the concentration of pollutants in the workshop. At the same time, safety fences and sensing devices are set up in the working area of the robot. Once someone accidentally enters, the machine will stop immediately to avoid collisions between the robotic arm and personnel. For painting processes that require high-temperature drying, robots can work stably in high-temperature environments without the need for personnel to approach, reducing the harm of high temperatures to the human body and freeing operators from harsh working environments to safer work positions such as equipment monitoring and parameter adjustment.
材料的精準控制與成本節約效果明顯。機器人系統通過精確計算工件的涂裝面積和所需涂料量,控制涂料的吐出量,避免了人工涂裝時因經驗不足導致的涂料浪費。在換色作業時,機器人配備的自動清洗裝置能快速清潔噴槍和管路,減少清洗劑的使用量和殘留在管路中的涂料損耗,尤其在多色涂裝生產線上,這一優勢更為顯著。此外,由于涂層質量穩定,返工率大幅降低,間接減少了涂料、能源和人工的重復投入,長期使用能為生產企業節省可觀的成本。
The precise control of materials and significant cost savings have been achieved. The robot system accurately calculates the coating area and required coating amount of the workpiece, controls the amount of coating ejected, and avoids the waste of coating caused by lack of experience during manual coating. During color changing operations, the robot is equipped with an automatic cleaning device that can quickly clean the spray gun and pipeline, reducing the amount of cleaning agent used and the loss of paint residue in the pipeline. This advantage is particularly significant in multi-color coating production lines. In addition, due to the stable coating quality, the rework rate is significantly reduced, indirectly reducing the repeated investment of coatings, energy, and labor. Long term use can save considerable costs for production enterprises.
