全自动超声波清洗线不是“单槽加机械手”那么简单——同一台设备，配错频率或烘干方式，精密件可能被打麻，光学件干完留水印。

The fully automatic ultrasonic cleaning line is not as simple as "single slot with mechanical arm" - the same equipment, with the wrong frequency or drying method, precision parts may be numb, and optical parts may leave watermarks after completion.

一、槽数是结果，不是起点

1、 The number of slots is the result, not the starting point

先排工艺链：粗洗（去重油/切屑）→ 精洗（超声空化）→ 喷淋漂洗 → 纯水终漂 → 切水/慢拉 → 烘干。三槽（佳木斯电机类案例）够中小批量；四槽起配航空件；七槽、八槽走曲轴、出口件的多级洁净。 槽多不代表出色，是“每多一道就少一种交叉污染”。

First, arrange the process chain: coarse washing (removing heavy oil/chips) → fine washing (ultrasonic cavitation) → spray rinsing → pure water final bleaching → water cutting/slow pulling → drying. Three slots (Jiamusi motor case) are sufficient for small and medium-sized batches; Four slots for aviation components; Multi level cleaning of seven slot and eight slot crankshafts and outlet components. Having more slots does not necessarily mean being high-end, it means that 'every additional one reduces one type of cross contamination'.

二、频率按工件材质切，不按习惯切

2、 Cut the frequency according to the material of the workpiece, not according to the usual practice

铸铁/曲轴/模具重油污：28kHz 低频，空化猛；

Heavy oil stains on cast iron/crankshaft/mold: 28kHz low frequency, strong cavitation;

精密五金/轴承：40kHz 均衡；

Precision hardware/bearings: 40kHz balanced;

光学镜片、镜面件：40+68kHz 双频或高频，配抛动+慢拉脱水，禁强碱、禁硬碰。

Optical lenses and mirror components: 40+68kHz dual frequency or high frequency, equipped with polishing and slow pulling dehydration, prohibited from strong alkali and hard touch.

铝、铜软材别堆功率密度，否则“洗干净了也麻了”。

Aluminum and copper soft materials should not be stacked with high power density, otherwise they will become numb even after being washed clean.

三、烘干方式决定良率下限

3、 Drying method determines the lower limit of yield

热风烘干通用；盲孔、腔体、硅片类建议上真空烘干（如 KRZD-HG 系列），不然内腔残水=装配隐患。光学件靠“慢拉+洁净热风”防印，不是把温度拉高就行。

Universal hot air drying; Blind holes, cavities, and silicon wafers must be vacuum dried (such as KRZD-HG series), otherwise residual water in the inner cavity will be a potential assembly hazard. Optical components rely on "slow pulling+clean hot air" to prevent printing, not just raising the temperature.

四、自动化看控制，不看过不过电

4、 Automation focuses on control, but without it, it's not about electricity

PLC+触摸屏+工位互锁是底线；能存工艺配方、记批次时间温度、对接 MES 的，才叫产线设备，不是“自动升降单槽”。循环过滤（10–50μm）、溢流、自动补液没配，槽液三天就废。

PLC+touch screen+workstation interlock is the bottom line; Equipment that can store process formulas, record batch time and temperature, and interface with MES is called production line equipment, not "automatic lifting single tank". Circulating filtration (10-50 μ m), overflow, and automatic replenishment were not prepared, and the tank solution was discarded within three days.

五、下单前必做带料试机

5、 Before placing an order, it is necessary to conduct a material testing machine

拿真实工件（带原厂油污、盲孔、毛刺）去厂里跑一轮，看：洁净度、水膜连续不破、烘干后有无斑、单篮节拍多少秒。只拿铝箔穿孔演示的，不算验证。

Take real workpieces (with original factory oil stains, blind holes, burrs) and run them around the factory to see: cleanliness, continuous water film without breakage, whether there are spots after drying, and how many seconds the single basket cycle time is. Demonstrating only aluminum foil perforation is not considered verification.

全自动线的本质，是把“洗—漂—干—不二次污染”锁成同一套节拍。选型顺序永远是：工件 → 污垢 → 频率功率 → 槽数 → 干燥 → 追溯。

The essence of a fully automated line is to lock the cycle of "washing bleaching drying secondary pollution" into the same rhythm. The selection order is always: workpiece → dirt → frequency and power → number of slots → drying → traceability.
