Description

—种墨盒、 墨盒芯片及芯片短路检测方法
技术领域
本发明涉及记录装置中芯片的检测技术， 特别是钎对芯片的短路自检 技术。
背景技术
记录装置， 例如打印机、 复印机、 传真机， 用于将要记录的信息通过 墨水等记录材料记录到纸张等记录介质上。 记录装置包括记录装置主体和 墨盒， 该墨盒可拆卸地安装在记录装置中。 为使记录装置能够判断所装入 的墨盒是否合适， 墨盒上往往配置有一芯片， 该芯片可拆卸地安装在所述 墨盒上。 所述芯片设有存储元件， 用于存储墨盒相关信息。 当墨盒安装在 记录装置上时， 墨盒上的芯片与记录装置之间建立电连接， 并与记录装置 主体之间进行数据交换。 具体的， 墨盒上的芯片与记录装置主体之间通过 端子进行电连接， 且每个端子均与芯片的存储元件相连接。
由于芯片包含与记录装置电连接的至少两个端子， 而这些端子间会存 在电压差， 随着芯片的使 )¾， 可能会有液滴或粉尘滴落在两个具有电压差 的端子之间， 例如电源端子与接地端子之间， 发生短路而导致存储元件被 损坏。
而且， 墨盒上除存储元件外， 还会设置有其它装置， 如其上施加有比 存储元件的驱动电压更高的高压电路， 如压电传感器或感应线圈、 电阻 等。 在这样的情况下， 存在 iil于一个装置的多个端子与用于另一个装置的 多个端子之间发生短路的危险， 而且， 这祥的短路可能会引起墨盒或记录 装置的损坏。
显然， 为了避免墨盒或记录装置受到损坏， 提前检测出上述短路现象 的发生是必要的。
一种用于检測芯片短路的现有技术， 在记录装置上设置有短路检測电 路， 该短路检测电路通过检测记录装置侧端子的电压变化来判断芯片上的 端子是否发生短路。 然而， 上述短路检测是在墨盒在记录装置上完成装机 检测后才进行的， 此时， 尽管短路现象被检测出， 但是存储元件可能已经 被损坏， 该墨盒也就无法再继续使用。 而且， 上述短路检测电路是设置在 记录装置上的， 故对于某些已推出市场、 未设有短路检测电路的记录装置 而言， 同样存在由于无法及时发现短路现象而致使墨盒或记录装置被损坏 的问题， 存在较大的安全隐患。
另一种芯片短路检測的现有技术, 芯片上设置有电池和短路检测电路， 通过电池为短路检测电路供电以完成芯片的短路检测， 在墨盒装入记录装置 后， 芯片与记录装置之间建立电连接， 通过检测芯片上短路检测端子的电压 变化， 或者通过检测芯片上短路检测端子和被检测端子间设置的信号变化， 来判断端子是否短路。 然而， 该现有技术需要在芯片上安装电池才能完成短 路检测， 会存在提高芯片的制造成本的问题， 并存在芯片长时间使用后电池 电量耗尽， 无法进行短路检测的问题。
