Description

针式打印机打印头检测仪
本实用新型属于维修针式打印机打印头的一种检测仪器，特别涉及一种针式打印机打印头检测仪。
目前针对针式打印机打印头维修时没有仪器检测，只能用本打印机打出的字来判断打印头的故障点，用户在维修时必须把打印机带上，这样给用户带来不便，也增加了维修困难，而针式打印机打印头检测仪未见报导。
本实用新型针对上述问题，设计了一种针式打印机打印头检测仪，这种检测仪备有各种型号针式打印机打印头的插座，维修时用户只要带上打印头即可，可以直接检测针式打印机打印头，解决了维修困难的问题，方便了用户。
图1为针式打印机打印头检测仪方框图。
图2为针式打印机打印头检测仪电路图。
本实用新型是这样实现的(如图2)：针式打印机打印头检测仪主要由电源(1)、桥式整流电路(2)、组合控制开关(3)、打印头插座(4)、振荡电路(5)组成，电源(1)为220V交流电压用开关K1控制，经变压器E与桥式整流电路(2)和滤波电容C1联接，滤波电容C1的正极与开关K3、K2联接后和继电器J的触点串联，负极与振荡电容C2的负极联接后和继电器J的线圈点联接，振荡电容C2的正极由开关K4控制继电器J的频率，组合控制开关(3)串联主电路来控制打印头的单针、全针检测，打印头插座(4)一点与限流电阻R联接，另外24点与组合控制开关(3)的每一点联接。
针式打印机打印头检测仪体积小，检测方便，能检测各种型号针式打印机打印头，维修时通过振荡能检测出打印头的故障。
下面结合(图2)描述一个实施例：整机为台式，面板有4个控制开关K1、K2、K3、K4，组合控制开关(3)与电源(1)、桥式整流电路(2)联接，开关K2与继电器J和组合控制开关(3)联接，开关K3与继电器J触点联接，开关K4与振荡电路(5)联接。
