Description
本发明涉及打印耗材领域，尤其是涉及一种电子图像成像设备使用的处理盒。本申请是基于申请日为2014年4月30日，申请号为CN201410182632.4的中国发明专利申请，该申请的内容引入本文作为参考。
图像成像设备是一种利用电子照相成像原理在记录材料上形成图像的设备，图像成像设备包括复印机、打印机、传真机等。在图像成像设备中使用的处理盒一般分为两种，一种是包括作为显影装置的显影辊和感光鼓的一体处理盒，另一种是将感光鼓分离到外的分体处理盒，上述两种处理盒均以可拆卸地方式安装到图像成像设备的主体中。
一个典型的图像成像设备激光打印机，激光打印机是目前最广泛的图像成像设备之一，激光打印机利用光、电、热的物理、化学原理在纸张等介质上输出文字或者图像。
专利号为US7715746的美国专利公开了一种激光打印机，参照图1，图1是该激光打印机1的结构图，激光打印机1包括主壳体，在主壳体的前端设置有前端盖11，主壳体和前端盖11围成容纳有机芯和处理盒的腔体，在主壳体的上方开设有出纸口12，在主壳体的下方设置有纸仓13，纸仓13内容纳有多张待印纸张。激光打印机1进行成像列印时，从纸仓13抽取纸张，纸张通过处理盒和机芯在其面上形成有图像，最后从出纸口12输出。
参照图2，当打开激光打印机1的前端盖11后，将安装在激光打印机11主壳体内的耗材安装支架14利用把手141沿箭头x的方向抽出后。可见，耗材安装支架14上安装有四个处理盒2，每个处理盒2均包括鼓单元和显影单元，四个处理盒2分别沿箭头x的方向上均匀地安装在耗材安装支架14上。
参照图3，图3为一个处理盒2与耗材安装支架14的分解图。处理盒2包括显影单元21和鼓单元22，其中，显影单元21可旋转地连接在鼓单元22的一侧上，并在显影单元21和鼓单元22之间形成有夹缝23。显影单元21的壳体围成容纳碳粉或显影剂的碳粉容纳腔，在该碳粉容纳腔内安装有显影辊、送粉辊、搅拌架、出粉刀和密封件等元件。鼓单元22的壳体围成容纳废粉的废粉容纳腔，在废粉容纳腔的开口处设有感光鼓，在感光鼓的端部安装有驱动组件，驱动组件和感光鼓可旋转地安装在鼓单元22中，在鼓单元相对于驱动组件的一个侧壁上还设置有固定端25和卡位部24。
在耗材安装支架14位于驱动组件的一侧上开设有驱动组件安装位142。处理盒2自上而下地安装到耗材安装支架14上时，驱动组件安装有驱动组件安装位142中，并穿过驱动组件安装位142到外接收激光打印机1的旋转驱动力，固定端25安装在耗材安装支架14另一内侧壁上，并通过卡位部24与耗材安装支架14邻接限制处理盒2在上下方向上的位置。处理盒2在其上方的外壁上还安装有耗材芯片3。
参照图4，图4是耗材芯片3与处理盒2的分解图。耗材芯片3包括基板，基板的下表面安装有电子模块31，电子模块内存储有生产日期、制造厂商、设备代码等不可变数据，同时也存储墨水余量、打印页数等需要更新的可变数据。基板的上表面设置有电连接部32，电连接部32包括电触点321和电触点322，多个电触点与电子模块的管脚电连接。处理盒2的外壁开设有耗材芯片安装位26，耗材芯片3安装在该安装位26上。
参照图5，图5是激光打印机1与耗材芯片3的局部分解图。在激光打印机1的主壳体内在对应耗材芯片3的位置上设置有连接装置，连接装置包括弹簧15、施压件16和基座17。弹簧17的一端抵接于激光打印机1，弹簧17的另一端抵接于施压件16，在施压件16上安装固定有基座17，并在基座17上设置有电触部181和电触部182。连接装置与耗材芯片连接时，由于在耗材芯片安装位26的两侧设置有定位凸肋，且在施压件16的两侧上设置有定位凹槽，所以激光打印机1与耗材芯片3连接时则需要定位凸肋与定位凹槽相互配合，以完成精确定位连接。
参照图6，图6是电触点和电触部连接时的原理图。当电触部181向下移动并与电触点321接触时，则如图6所示的电触部181虚线的状态下首次与电触点321接触，随后施加外力再将电触点321向下安装，由于电触部181具有弹性，所以电触部181则向一侧滑动并发生形变，并与首次与电触点321接触的位置发生位移。该位移的发生在提高电触部181与电触点321的电连接稳定性的同时，由于电触部181在电触点321的表面上进行滑动一段位移，而使得电触部181能够清洁付在电触点321上的污染物，从而提高电连接的稳定性。此外，通过电触部181和电触点321的电连接，从而实现耗材芯片3与激光打印机1的主控电路的电连接。
然而，从图3和图4可见，耗材芯片3是以水平地形式安装在处理盒2上方的外壁上，且电连接部32也是水平地设置，由于在显影单元21和鼓单元22之间形成有夹缝23，所以在抽出耗材安装支架14后，极其细小的碳粉或者细小的粉尘容易从该夹缝23中从处理盒2中漂浮到处理盒2外，并落在电连接部32上，从而造成电连接部32的污染，从而严重影响电连接部32电连接性能。同时，由于水平放置的耗材芯片3也不利于污染物的清洁，当污染物越积越多的时候，则单靠电触部181则无法很好地对耗材芯片3上的污染物进行清洁，从而导致耗材芯片3与激光打印机1的电连接失败，继而导致无法正常工作。
同时，参照图5，电触部181与耗材芯片3的电连接是依靠定位凸肋与定位凹槽相互配合定位的，由于定位凸肋与定位凹槽的容错性差，所以激光打印机1使用时间长后，如部分零件出现损耗，则导致定位凸肋与定位凹槽无法互相配合固定，从而导致电连接失败。
参照图6，由于电触部181是通过垂直挤压耗材芯片3的电触点321，从而导致电触部181与电触点321的接触面积小，继而导致电触部181的接触受力较大，容易造成电触部的断裂或变形，在电触部损毁后需要专业人士才能进行维修或更换，给使用人员造成诸多不便，也给使用人员增加了使用成本。
为了客服现有技术的不足，本发明的目的提供一种具有良好耐用性和电连接稳定性的处理盒。
为了实现本发明的主要目的，本发明提供一种处理盒，包括显影单元和鼓单元，显影单元的壳体围成容纳碳粉的粉仓，鼓单元的壳体围成容纳废粉的废粉仓，粉仓的出口处可旋转地安装有显影辊，废粉仓的出口处可旋转地安装有感光鼓，感光鼓的一端上驱动组件，驱动组件包括安装部，安装部上设置有凸起，驱动组件可旋转地安装在壳体的第一侧壁上，在第一侧壁相对的第二侧壁上安装有耗材芯片，耗材芯片包括基板、在基板设置的电子模块和与电子模块电连接的电连接部，其中，电连接部背向第一侧壁的方向倾斜地设置在基板上。
一个优选的方案是，基板背向第一侧壁的方向倾斜地设置在第二侧壁上。
进一步的方案是，第二侧壁上设置有耗材芯片安装位，耗材芯片安装位沿基板的倾斜方向所设置，耗材芯片安装在耗材芯片安装位上。
更进一步的方案是，在耗材芯片安装位的外周上设置有限位部，限位部沿耗材芯片安装位的外周延伸设置。
更进一步的方案是，处理盒还包括弹性件，弹性件设置在基板和耗材芯片安装位之间。
更进一步的方案是，弹性件为海绵。
更进一步的方案是，弹性件为弹簧，弹簧安装在设置在耗材芯片安装位上的弹簧安装孔中，弹性件的第一端抵接于基板，弹性件的第二端抵接于弹簧安装孔的底壁。
更进一步的方案是，电连接部包括多个电触点，多个电触点均沿背向第一侧壁的方向倾斜地延伸设置。
本发明提供的处理盒也可以是包括显影单元和鼓单元，显影单元的壳体围成容纳碳粉的粉仓，鼓单元的壳体围成容纳废粉的废粉仓，粉仓的出口处可旋转地安装有显影辊，废粉仓的出口处可旋转地安装有感光鼓，显影辊的一端上驱动组件，驱动组件包括安装部，安装部上设置有凸起，驱动组件可旋转地安装在壳体的第一侧壁上，在第一侧壁相对的第二侧壁上安装有耗材芯片，耗材芯片包括基板、在基板设置的电子模块和与电子模块电连接的电连接部，其中，电连接部背向第一侧壁的方向倾斜地设置在基板上。
由于激光打印机上的电触部朝向安装有驱动组件的第一侧壁倾斜且具有较大的接触面，所以将耗材芯片的电连接部背向该第一侧壁的方向倾斜地设置，通过倾斜地将电触部和电连接部进行接触连接有利于更好地保护电触部。同时，由于是利用斜面进行电连接，所以具有较大接触面积，在提高电连接稳定性和电连接容错性的同时，也大大减少了电触部的接触受力，从而有效地保护激光打印机和处理盒的电连接结构，继而倾斜设置的电连接部可通过重力的作用，使得在其表面上的碳粉或粉尘自上而下地滑出电连接部，有利于提高电连接的稳定性。
此外，倾斜设置的基板有利于电连接部更稳定地安装在基板上，通过基板即可实现电连接部的倾斜设置，同时也提高生产加工效率。
并且，通过耗材芯片安装位可使耗材芯片在安装该安装位中后，即可实现耗材芯片的倾斜设置，从而提高生产加工效率。
另外，限位部用于限制耗材芯片的位置，通过稳固耗材芯片的位置，从而提高电触部和电触电连接时的稳定性。
并且，弹性件有利于为电触部和电触电连接时提供缓冲力，使得电触部和电触点电连接时更加平稳，该缓冲力也有利于保护电触部免受刚性破坏，当弹性件为海绵时，不仅能够为耗材芯片提供缓冲力，还能够起绝缘保护作用，采用弹簧时，则能够为耗材芯片提供足够的缓冲力。
此外，通过电触点沿背向第一侧壁的方向倾斜地延伸，有利于增大导电面积，从而提高电连接的容错性，提高电连接部的稳定性。
本发明提供的处理盒采用倾斜设置的耗材芯片，除了应用在驱动组件设置在感光鼓的处理盒上，还可以设置在驱动组件设置在显影辊的处理盒上，通过该处理盒提高电连接稳定性和电连接容错性的同时，也有效地保护激光打印机和处理盒的电连接结构，从而提高激光打印机和处理盒的耐用性。

以下结合附图及实施例对本发明作进一步说明。
参照图7和图8，处理盒4包括显影单元41和鼓单元42，显影单元41安装在鼓单元42的一侧上，显影单元42壳体围成容纳有碳粉的粉仓，在粉仓的开口处设置有显影辊(未示出)。鼓单元42壳体围成容纳有废粉的废粉仓，在废粉仓的开口处设置有感光鼓(未示出)，在感光鼓的端部安装有驱动组件53，驱动组件53包括安装部532，在安装部532上沿轴向形成有三个非扭曲形状的凸起531，三个凸起531沿周向均匀地布置在安装部532的靠外的端部上，驱动组件53用于接收外部旋转驱动力，且感光鼓和驱动组件53是可旋转地安装在处理盒的第一侧壁51上。在与第一侧壁51相对的第二侧壁52上安装有耗材芯片6。优选地，驱动组件除了安装在感光鼓上，驱动组件还可以设置在显影辊的端部。
参照图9和图10，耗材芯片6包括基板61，在基板61上设置有电子模块(未标示)，在基板背向第一侧壁51的表面上设置电触点62和电触点63，电触点62和电触点63组成了耗材芯片6的电连接部，电子模块通过电触点62和电触点63与外界进行交互通讯。在第二侧壁52的上方设置有耗材芯片安装位43，耗材芯片安装位43背向第一侧壁51的方向倾斜地设置在第二侧壁52的上方，在耗材芯片安装位43上开设有弹簧安装孔45。
处理盒4还包括沿耗材芯片安装位43的外周上设置有限位部45。当需要将耗材芯片6安装到耗材芯片安装位43时，首先将弹簧46安装到弹簧安装孔45中，并使弹簧45的第一端抵接于弹簧安装孔45的底壁，再将耗材芯片6***到耗材芯片安装位43中，使弹簧45的第二端抵接于耗材芯片6的基板61。由于弹簧45的预置有预压力，继而使得基板61与限位部44邻接，从而耗材芯片6相对地固定在耗材芯片安装位43中。优选地，弹簧45还可以采用具有弹性和绝缘性的海绵替代，可将海绵设置耗材芯片6和耗材芯片安装位43之间，同样可实现将耗材芯片6相对地固定在耗材芯片安装位43中。
由于耗材芯片安装位43背向第一侧壁51的方向倾斜地设置，使得基板61安装到耗材芯片安装位43上即可实现基板61背向第一侧壁51的方向倾斜地设置，同时也实现了设置在基板61上的电触点62和电触点63背向第一侧壁51的方向倾斜地设置。优选地，电触点62和电触点63可沿倾斜方向延伸设置，从而有利于增大接触面积。
参照图11，图11是电触点62与电触部74电连接时的局部原理图。在激光打印机的主壳体内在对应耗材芯片6的位置上设置有连接装置，连接装置包括弹簧71、施压件72和基座73。在施压件72上安装固定有基座73，并在基座73上设置有电触部74。当电触部74向下移动并与电触点62接触时，由于电触部74朝向安装有驱动组件的第一侧壁51倾斜且具有较大的接触面741，且电触点62背向该第一侧壁51的方向倾斜地设置，所以随后施加外力再将电触点321向下安装，由于电触部181具有弹性，所以电触部74向一侧滑动并发生形变并通过接触面741与电触点62接触。同时，由于电触部74相对于电触点62的位置发生位移，所以电触部74通过滑动将粘附在电触点62的污染物刮走，污染物还可以在重力的作用下从电触点62脱离。
相比于通过垂直挤压和点接触的方式来实现电接触，本发明的处理盒通过将耗材芯片的电连接部背向第一侧壁的方向倾斜地设置，通过将电触部和电连接部进行倾斜地接触连接有利于更好地保护电触部。同时由于是利用斜面进行电连接，所以具有较大接触面积，在提高电连接稳定性和电连接容错性的同时，也大大减少了电触部的接触受力，从而有效地保护激光打印机和处理盒的电连接结构，继而倾斜设置的电连接部可通过重力的作用，使得在其表面上的碳粉或粉尘自上而下地滑出电连接部，有利于提高电连接的稳定性。
