【摘要】：重力式芯片处理机的关键控制技术以逻辑动作控制、实时动态报警机制和芯片温度控制等技术最为重要。重力式芯片处理机的处理能力受到执行机构的逻辑动作、报警解除、芯片加热时间和加热准确度等条件的制约。执行机构数量多、工艺繁琐复杂是实现逻辑动作控制的一个难点,报警机制的合理性决定了处理机JAM率(故障率)的高低;芯片温度加热控制过程中,被控对象种类和数量多,控制器控制参数整定费时费力,温度加热时间长、超调量大、芯片内部温度不能直接测量等问题,也是影响重力式芯片处理机高效率的主要原因。根据重力式芯片处理机的本体结构和芯片的流动工艺,设计各分部执行机构的逻辑动作控制,完成待测芯片从投入到分选并收纳的整个动作过程。运用控制器、组态界面和实时数据库设计动态报警系统,实现报警信息的记录、动态实时报警查询、历史报警数据查询和按条件报警查询等功能。设计人机交互界面,实现重力式芯片处理机运行状态可视化,采集相应信息和数据。芯片加热采用多段加热、逐段温度补偿的控制方案,完成芯片从常温到测试温度的加热过程。针对控制器参数整定繁琐复杂的问题,同时为达到加快系统动态响应、缩短温度调节时间和抑制温度超调的控制目的,提出一种基于继电反馈的参数自整定和动态积分分离相结合的控制算法。通过系统辨识得到被控对象的数学模型,在此基础上运用仿真对该算法进行理论验证,最后通过重力式芯片处理机芯片加热实际测试,进一步验证了该算法的有效性和合理性。随着重力式芯片处理机的投入使用,设计合理的芯片流动控制策略和报警机制确保了处理机的高效性和快速性,实际运行测试数据表明,处理机平均日处理量为28000枚,平均JAM率低于0.5‰。在芯片温度控制过程中,实现控制器控制参数自整定功能,同时缩短温度调节时间,抑制温度超调,符合芯片在高温测试模式的工艺要求。
[Abstract]:The key control techniques of gravity chip processor are logic action control, real-time dynamic alarm mechanism and chip temperature control. The processing capacity of the gravity chip processor is restricted by the logic action of the executing mechanism, alarm release, chip heating time and heating accuracy. It is difficult to realize the logic action control because of the large number of actuators and complicated process. The rationality of alarm mechanism determines the JAM rate (failure rate) of processor, and in the process of chip temperature heating control, there are many kinds and number of controlled objects. The main reasons for the high efficiency of the gravity chip processor are that the controller control parameter setting takes time and effort, the temperature heating time is long, the overshoot is large, and the temperature inside the chip can not be measured directly, which also affects the high efficiency of the gravity chip processor. According to the structure of gravity chip processor and the flow process of the chip, the logical action control of the executive mechanism of each branch is designed, and the whole operation process of the chip to be tested from input to sorting and receiving is completed. The dynamic alarm system is designed by using controller, configuration interface and real-time database. The functions of recording alarm information, dynamic real-time alarm query, historical alarm data query and conditional alarm query are realized. The man-machine interface is designed to realize the visualization of the running state of the gravity chip processor and to collect the corresponding information and data. The chip heating is controlled by multi-stage heating and piecewise temperature compensation to complete the heating process from normal temperature to test temperature. In order to speed up the dynamic response of the system, shorten the temperature adjustment time and restrain the temperature overshoot, the controller parameters are complicated and complicated. A control algorithm based on relay feedback is proposed, which combines parameter self-tuning and dynamic integral separation. The mathematical model of the controlled object is obtained by system identification. On this basis, the algorithm is theoretically verified by simulation. Finally, the validity and rationality of the algorithm are further verified by the actual heating test of the gravity chip processor. With the application of gravity chip processor, reasonable chip flow control strategy and alarm mechanism are designed to ensure the efficiency and rapidity of the processor. The actual test data show that the average daily processing capacity of the processor is 28000. The average JAM rate was less than 0.5 鈥，
