The coating assembly line is suitable for the coating and spraying treatment of workpiece surfaces. It is mainly used for the coating of single or small batch workpieces, and forms transportation operations with transportation machinery such as suspension conveyors, electric track cars, and ground conveyors. Its seven major components mainly include pre-treatment equipment, coating equipment, powder spraying system, oven drying, heat source system, electrical control system, suspension conveyor chain, etc.

預處理設備

Pretreatment equipment

噴淋式多工位前處理裝置是表面處理的常用設備。其原理是通過機械沖刷加速化學反應，完成脫脂、磷化、水洗等工藝過程。鋼鐵零件噴涂預處理的典型工藝是預脫脂、脫脂、水洗、表面調理和磷化。拋丸機也可用于預處理，適用于結構簡單、腐蝕嚴重、無油或少油、無水污染的鋼件。

The spray type multi-station pre-treatment device is a commonly used equipment for surface treatment. The principle is to accelerate chemical reactions through mechanical flushing, completing processes such as degreasing, phosphating, and water washing. The typical processes for spray pretreatment of steel parts are pre degreasing, degreasing, water washing, surface conditioning, and phosphating. The shot blasting machine can also be used for pre-treatment, suitable for steel parts with simple structure, severe corrosion, no or little oil, and no water pollution.

噴漆設備

Painting equipment

如噴油室和水幕噴漆室，可廣泛用于自行車、汽車板簧和大型裝載機的表面涂裝流水線。

Such as oil spray chambers and water curtain spray chambers, they can be widely used in surface coating assembly lines for bicycles, automotive leaf springs, and large loaders.

粉末噴涂系統

Powder spraying system

粉末噴涂中的小型旋風過濾回收裝置是一種先進的快速變色粉末回收裝置。噴粉系統關鍵部件推薦進口產品，噴粉室、電動機械升降機等部件全部國產化。

The small cyclone filtration and recovery device in powder spraying is an advanced rapid discoloration powder recovery device. The key components of the powder spraying system are recommended to be imported products, and all components such as the powder spraying room and electric mechanical elevator are domestically produced.

它是烘箱涂布生產線中的重要設備之一，其溫度均勻性是保證涂布質量的重要指標。烘箱的加熱方式有輻射、熱風循環和輻射熱風循環。按生產程序可分為單室和直通式，設備形式有直通式和橋式。循環式熱風爐具有保溫、均勻性好、熱損失低等優點。通過實驗，烘箱內溫差小于3oC，可達到先進國家同類產品的性能指標。

It is one of the important equipment in the oven coating production line, and its temperature uniformity is an important indicator to ensure coating quality. The heating methods of the oven include radiation, hot air circulation, and radiation hot air circulation. According to production procedures, it can be divided into single room and through type, with equipment forms including through type and bridge type. The circulating hot air stove has advantages such as insulation, good uniformity, and low heat loss. Through experiments, the temperature difference inside the oven is less than 3oC, which can meet the performance indicators of similar products in advanced countries.

熱源系統

Heat source system

熱風循環是一種應用廣泛的加熱方式，利用對流傳導原理加熱烘箱，使工件干燥固化。根據用戶的具體情況，可以選擇電、蒸汽、燃氣或燃料作為熱源。熱源可根據烤箱條件確定，放置在頂部、底部和側面。

Hot air circulation is a widely used heating method that uses the principle of convective conduction to heat the oven and dry and solidify the workpiece. According to the specific situation of the user, electricity, steam, gas, or fuel can be selected as the heat source. The heat source can be determined based on the oven conditions and placed at the top, bottom, and sides.

電子控制系統

electronic control system 

鍍膜和涂裝流水線電控有集中控制和單排控制。集中控制可以用可編程邏輯控制器(PLC)控制上位機，自動控制各個過程，并根據編制的控制程序進行數據的采集、監視和報警。單線控制是涂裝生產線中常見的控制方式。各工序單線控制，電控箱(柜)設置在設備附近，成本低，操作簡單，維護方便。

The electric control of the coating and coating assembly line has centralized control and single row control. Centralized control can use programmable logic controllers (PLCs) to control the upper computer, automatically control various processes, and collect, monitor, and alarm data according to the programmed control program. Single line control is a common control method in painting production lines. Single line control for each process, with electronic control boxes (cabinets) located near the equipment, low cost, simple operation, and convenient maintenance.

懸掛輸送鏈

Suspension conveyor chain

懸掛輸送機是涂裝流水線的工業流水線和輸送系統。產品懸掛輸送機適用于L=10-14M的倉儲貨架和異型路燈用合金鋼管涂裝線。工件吊裝在專用吊架上(承重500-600KG)，進出道路暢通。道岔按作業指導書由電氣控制開閉，以滿足各加工工位工件自動輸送、強冷間和裝車區平行堆垛冷卻的要求，強冷區設置吊架識別和牽引報警停車裝置。

The suspension conveyor is an industrial assembly line and conveying system for the coating assembly line. The product suspension conveyor is suitable for L=10-14M storage shelves and alloy steel pipe coating lines for special-shaped street lights. The workpiece is lifted on a dedicated hanger (with a load capacity of 500-600KG), and the access road is unobstructed. The switch is electrically controlled to open and close according to the operation instructions, in order to meet the requirements of automatic conveying of workpieces at each processing station, parallel stacking and cooling in the strong cooling room and loading area. The strong cooling area is equipped with hanger recognition and traction alarm parking devices.

涂裝流水線的組件由以上七部分組成。它的設備工件結構簡單，操作簡單，管理維護都很好，速度更快。

The components of the painting assembly line are composed of the above seven parts. Its equipment has a simple workpiece structure, simple operation, good management and maintenance, and is faster.
