　　一、设备技术架构解析

　　1、 Analysis of Equipment Technical Architecture

　　多槽手动超声波清洗机由清洗槽体、超声波发生器、换能器及控制系统构成。其核心创新在于多槽独立计时器设计，每个清洗槽均配备高精度计时模块，可实现0.1秒级的时间分辨率。设备工作原理如下：

　　The multi slot manual ultrasonic cleaning machine consists of a cleaning tank body, an ultrasonic generator, a transducer, and a control system. Its core innovation lies in the design of multi slot independent timers, with each cleaning slot equipped with a high-precision timing module that can achieve a time resolution of 0.1 seconds. The working principle of the equipment is as follows:

　　超声波清洗原理：超声波发生器将电能转换为高频电信号，驱动换能器产生20kHz-40kHz的机械振动。这种振动在清洗液中形成微小气泡（空化核），气泡破裂时产生局部高温高压（空化效应），有效剥离工件表面污染物。

　　Ultrasonic cleaning principle: The ultrasonic generator converts electrical energy into high-frequency electrical signals, driving the transducer to generate mechanical vibrations of 20kHz-40kHz. This vibration forms tiny bubbles (cavitation nuclei) in the cleaning solution, which generate local high temperature and high pressure (cavitation effect) when the bubbles rupture, effectively peeling off surface pollutants of the workpiece.

　　多槽协同机制：设备通常配置预清洗、主清洗、漂洗、干燥等多个功能槽。各槽体通过独立计时器实现工序衔接，如预清洗槽设置3分钟超声波清洗，主清洗槽设置5分钟复合清洗，漂洗槽设置2分钟纯水冲洗，干燥槽设置10分钟热风循环。

　　Multi slot collaborative mechanism: The equipment is usually equipped with multiple functional slots such as pre cleaning, main cleaning, rinsing, and drying. Each tank is connected to the process through an independent timer. For example, the pre cleaning tank is equipped with 3-minute ultrasonic cleaning, the main cleaning tank is equipped with 5-minute composite cleaning, the rinsing tank is equipped with 2-minute pure water flushing, and the drying tank is equipped with 10 minute hot air circulation.

　　智能控制系统：采用触摸屏人机界面，支持10组以上工艺程序存储。操作人员可通过数字编码器设定各槽工作时间，系统自动校准时钟偏差，确保多槽工序同步率达99.9%。

　　Intelligent control system: adopting touch screen human-machine interface, supporting storage of more than 10 sets of process programs. The operator can set the working time of each slot through a digital encoder, and the system automatically calibrates the clock deviation to ensure a synchronization rate of 99.9% for multi slot processes.

　　二、独立计时器管理策略

　　计时模块设计：采用石英晶体振荡器作为时基源，配合32位微处理器，实现±0.01%的计时精度。每个计时模块配备独立电源，避免电压波动干扰。

　　Timing module design: Using a quartz crystal oscillator as the time base source, combined with a 32-bit microprocessor, to achieve a timing accuracy of ± 0.01%. Each timing module is equipped with an independent power supply to avoid voltage fluctuations and interference.

　　动态补偿算法：内置温度补偿电路，当环境温度变化时，自动调整计时参数。实测显示，在10℃-40℃范围内，计时误差始终控制在0.1秒以内。

　　Dynamic compensation algorithm: Built in temperature compensation circuit, automatically adjusts timing parameters when the ambient temperature changes. Actual testing shows that the timing error is always controlled within 0.1 seconds within the range of 10 ℃ -40 ℃.

　　2. 工序衔接优化

　　级联控制模式：支持前槽计时结束自动触发后槽启动，实现无缝工序转换。在漂洗槽计时完成后，系统自动关闭超声波电源，开启排水阀门，同时启动干燥槽加热装置。

　　Cascade control mode: supports automatic triggering of rear slot start when the front slot timer ends, achieving seamless process transition. After the rinsing tank timer is completed, the system automatically turns off the ultrasonic power, opens the drainage valve, and starts the drying tank heating device.

　　异常处理机制：当某槽体计时未完成时，系统自动锁定后续工序，防止工艺流程紊乱。操作人员可通过紧急停止按钮中断当前工序，设备自动保存当前状态。

　　Exception handling mechanism: When the timing of a certain tank is not completed, the system automatically locks the subsequent processes to prevent process flow disorder. The operator can interrupt the current process by pressing the emergency stop button, and the equipment automatically saves the current status.

　　3. 操作界面设计

　　3. User interface design

　　可视化编程：采用图形化编程界面，支持工序流程的拖拽式编排。每个槽体的计时参数、超声波功率、温度设定等均可独立调整。

　　Visual programming: adopting a graphical programming interface, supporting drag and drop arrangement of process flow. The timing parameters, ultrasonic power, temperature settings, etc. of each tank can be independently adjusted.

　　权限管理：设置三级操作权限，普通操作员仅能调用预设程序，工程师可修改工艺参数，管理员拥有系统配置权限。所有操作记录自动存档，支持USB数据导出。

　　Permission management: Set three-level operation permissions. Ordinary operators can only call preset programs, engineers can modify process parameters, and administrators have system configuration permissions. All operation records are automatically archived and support USB data export.
