摘　　要：为了改进打点标记作业模式,提高标记作业效率,设计了全自动芯片打点装置。该设计将PLC步进电机控制技术、人机界面技术、脉冲分配计算算法等技术融合,开发出一套由打点机械装置本体、传感检测与步进控制、人机界面组成的全自动芯片打点装置。试验结果表明:转速为200 r/min时,3 mm尺寸芯片的位置控制效果比8 mm芯片差,但所有3 mm芯片标点位置都落在芯片表面,某些芯片表面文字被覆盖;而8 mm芯片所有标点都落在芯片表面空白处。当转速降低到100 r/min时,3 mm尺寸芯片的位置精度也能满足要求。因此,该打点装置完全满足于8 mm及以上尺寸芯片,如果允许打点标记覆盖芯片表面标识码或降低系统运转速度,该打点装置也可用于小尺寸芯片,具有一定的实际应用价值。In order to improve operation mode and work efficiency of chip marking,the full automatic chip marking device had been designed.The design covered the PLC control for stepper motor technology,human-machine interface technology,pulse distribution algorithm,and so on.Developed automatic chip marking device composed of machines body,sensor detection and step control,human-machine interface.Test results indicated that the control error of 3 mm size chip was greater than the 8 mm at 200 r/ min,but all the 3 mm chip of marking fell on the chip space surface.Some chip surface text was covered.All the 8mm chip of marking felt on the chip surface.When the speed reduced to 100 r/min,the position accuracy of the 3 mm size chip can also met the requirements.Therefore,this device completely satisfy with 8mm chip size and larger.If the chip code can be covered by marking or reduce the system speed,this device can also be used for small-size chip and has a certain practical value
