图1为本发明实施例提供的一种成像组件的结构示意图,如图1所示,该成像组件包括感光鼓20和磁性件21。磁性件21随着感光鼓20的转动而发生位移。磁性件21用于在感光鼓20转动时与磁感应件相对移动生成感应电流,感应电流用于确定成像组件是否符合预期。FIG. 1 is a schematic structural diagram of an imaging assembly provided by an embodiment of the present invention. As shown in FIG. 1 , the imaging assembly includes a
作为一种可选方案,至少一个磁性件21可设置于感光鼓20上,例如,至少一个磁性件21可位于感光鼓20的第一端。磁性件21与感光鼓20围绕同一轴线转动。本发明实施例中,磁性件21可包括永磁体或电磁铁。As an optional solution, at least one
该成像组件还包括驱动部件22,至少一个磁性件21设置于驱动部件22上,磁感应件与磁性件21相对设置并能够相对位移,驱动部件22与感光鼓20同步转动,从而实现与感光鼓20的传动配合。图2为本发明实施例提供的一种驱动部件的结构示意图,如图1和图2所示,驱动部件22设置于感光鼓20的第一端,磁性件21设置于驱动部件22上。感光鼓20的形状为圆柱形;驱动部件22为齿轮,为配合感光鼓20的形状设计,驱动部件22的形状也为圆柱形。在实际应用中,感光鼓20和驱动部件22还可以设置为其它形状,此处不再一一列举。如图2所示,设置于驱动部件22上的磁性件21的数量可以为多个,作为一种可选方案,多个磁性件21围绕驱动部件22的中心点均匀排布。图2中示出了八个磁性件21,八个磁性件21围绕驱动部件22的中心点均匀排布。The imaging assembly also includes a driving
本发明实施例提供的成像组件的技术方案中,磁性件随着感光鼓的转动而发生位移,磁性件用于在感光鼓转动时与磁感应件相对移动生成感应电流,而若感光鼓不转动时则不会生成感应电流,因此感应电流能够表征感光鼓是否转动,从而实现了通过感应电流确定感光鼓是否正常工作,成像组件是否符合预期,进而确定出处理盒是否符合预期。In the technical solution of the imaging assembly provided by the embodiment of the present invention, the magnetic part is displaced with the rotation of the photosensitive drum, and the magnetic part is used to move relative to the magnetic induction part to generate an induced current when the photosensitive drum rotates, and if the photosensitive drum does not rotate Then no induced current will be generated, so the induced current can represent whether the photosensitive drum is rotating, so as to realize whether the photosensitive drum is working normally, whether the imaging component meets expectations, and then determine whether the process cartridge meets expectations through the induced current.
其中,处于工作阶段或测试阶段时,需要感光鼓转动,若此时没有感应电流产生则说明感光鼓没有转动,则感光鼓没有正常工作,也就无法完成工作或测试,成像组件及处理盒不符合预期。Wherein, when in the working stage or testing stage, the photosensitive drum needs to be rotated. If there is no induction current at this time, it means that the photosensitive drum is not rotating. In line with expectations.
另外,根据感光鼓的转速,形成的感应电流的大小也会相应变化,例如随着工作或测试阶段的变化,感光鼓的转速可能由低速变为高速,若感光鼓正常工作或测试时,感应线圈切割磁感线的速度加快,生成的感应电流也会增大,但是若感光鼓没有正常工作或测试时,生成的感应电流的变化趋势可能不符合预期,例如感应电流没有变化;或感应电流减小;或感应电流增加的量不符合预期,均可以用于判断感光鼓没有正常工作,成像组件及处理盒不符合预期。In addition, according to the rotation speed of the photosensitive drum, the size of the induced current will also change accordingly. For example, with the change of the working or testing stage, the rotation speed of the photosensitive drum may change from low speed to high speed. The speed at which the coil cuts the magnetic induction line is accelerated, and the generated induced current will also increase. However, if the photosensitive drum is not working normally or during the test, the change trend of the generated induced current may not meet expectations, for example, the induced current does not change; or the induced current Decrease; or the increase of the induced current does not meet expectations, both can be used to judge that the photosensitive drum is not working normally, and the imaging components and process cartridges are not as expected.
另外,当图像形成装置处于不同的工作或测试阶段时,感光鼓的转速不同,此时感应电流也具有相应的数值范围,因此可通过检测图像形成装置处于某一工作或测试阶段时感应电流的数值,并与上述工作或测试阶段下预期的感应电流的数值范围进行比对,若检测得到的感应电流的数量不符合上述数值范围,则可认为感光鼓没有正常工作,则成像组件及处理盒不符合预期。In addition, when the image forming device is in different working or testing stages, the rotation speed of the photosensitive drum is different, and the induced current also has a corresponding value range at this time, so the induced current can be detected by detecting the value of the induced current when the image forming device is in a certain working or testing stage value, and compare it with the value range of the expected induced current during the above work or test stage. If the detected amount of induced current does not meet the above value range, it can be considered that the photosensitive drum is not working normally, and the imaging component and the process box Not as expected.
图3为本发明实施例提供的另一种成像组件的结构示意图,如图3所示,本实施例中的成像组件在图1所示的成像组件的基础上还包括检测件5,该检测件5用于输出与感应电流对应的检测电流,检测电流随着感光鼓20的转速的增大而增大,检测电流用于确定成像组件是否符合预期。Fig. 3 is a schematic structural diagram of another imaging assembly provided by an embodiment of the present invention. As shown in Fig. 3, the imaging assembly in this embodiment further includes a
检测件5与处理盒芯片6电连接。检测件5可包括光敏元件,例如,光敏元件可包括光敏电阻或光敏二极管。检测件5可通过导线或金属触点与处理盒芯片6电连接。本发明实施例中,处理盒芯片6可拆卸的安装于处理盒上,并且,处理盒芯片6还与图像形成装置的主控芯片电连接。需要说明的是:主控芯片在图中未具体画出。为使得消电件1发出的光线能够照射到检测件5,检测件5可位于感光鼓20的第二端,其中,第二端与第一端相对设置。The
如图3所示,作为一种可选方案,感光鼓20的第二端也可设有驱动部件,以便于与第一端设置的驱动部件共同驱动感光鼓20转动。第二端设置的驱动部件可与第一端设置的驱动部件相同,第二端设置的驱动部件为齿轮,在图3中第二端设置的驱动部件未具体画出。As shown in FIG. 3 , as an optional solution, the second end of the
检测件5在光线的照射下产生与感应电流对应的检测电流,并将检测电流输出至处理盒芯片6。其中,检测电流为光电流。进而,处理盒芯片6将感应电流转换为模拟电压并将模拟电压输出至主控芯片,以供主控芯片根据模拟电压检测出状态信息。The
检测件5产生的检测电流的大小与感光鼓20的转速成正比,感光鼓20转速越大时,检测件5产生的检测电流越大,进而由感应电流转换的模拟电压越大;或者,感光鼓20转速越小时,检测件5产生的检测电流越小,进而由检测电流转换的模拟电压越小。针对不同的模拟电压,主控芯片检测出的状态信息也不同,状态信息可包括第一状态信息或第二状态信息。具体地,主控芯片可根据较大的模拟电压A检测出模拟电压A对应的第一状态信息;和/或,主控芯片可根据较小的模拟电压B检测出模拟电压B对应的第二状态信息。例如,感光鼓20从不转动到慢速转动的过程中,主控芯片接收到的模拟电压会缓慢地从0V升至5V,则可根据该模拟电压检测出第二状态信息;和/或,感光鼓20从缓慢转动到快速转动的过程中,主控芯片接收到的模拟电压会缓慢地从5V升至10V,则可根据该模拟电压检测出第一状态信息。因此,主控芯片检测出第一状态信息时表明检测件5产生的检测电流较大,而主控芯片检测出第二状态信息时表明检测件5产生的检测电流较小。但是只要主控芯片能够接收到模拟电压,进而能够根据模拟电压检测出第一状态信息和/或第二状态信息,无论模拟电压的大小,均能确定出处理盒是否符合预期。The magnitude of the detection current generated by the
本发明实施例中,通过在处理盒中设置检测件,主控芯片可根据检测件产生的检测电流检测出状态信息,进而根据状态信息确定出处理盒可以使用,该处理盒和图像形成装置是匹配的。In the embodiment of the present invention, by setting the detection element in the process box, the main control chip can detect the state information according to the detection current generated by the detection element, and then determine that the process box can be used according to the state information. The process box and the image forming device are matched.
在判断感光鼓是否正常工作时,可直接获取感应电流的数值;也可通过将感应电流用于其他功能,并对相应功能产生的效果进行检测,例如将感应电流用于发光,通过对光强进行检测,间接对感应电流的大小进行判断,或感应电流用于加热,通过对加热温度进行检测,间接对感应电流的大小进行判断。可以理解的是,间接对感应电流的大小进行判断的方式并不仅仅为上述两种。When judging whether the photosensitive drum is working normally, the value of the induced current can be obtained directly; the induced current can also be used for other functions, and the effect of the corresponding function can be detected, for example, the induced current can be used for lighting, and the light intensity can be measured The detection is performed to indirectly judge the magnitude of the induced current, or the induced current is used for heating, and the magnitude of the induced current is indirectly judged by detecting the heating temperature. It can be understood that the methods for indirectly judging the magnitude of the induced current are not limited to the above two methods.

Fig. 7 is a flow chart of a power elimination method provided by the embodiment of the present invention, Fig. 8 is a schematic diagram of the working principle of the power eliminating device in the embodiment of the present invention, and Fig. 9 is a schematic diagram of the working principle of the rectification and filtering circuit in the embodiment of the present invention. The method for dissipating power of the imaging component will be described in detail below with reference to FIGS. 7 to 9 . As shown in Figure 7, the power elimination method includes:
步骤102、磁感应件与磁性件相对位移,使磁感应件产生感应电流。
如图6和图8所示,驱动部件22转动以带动感光鼓20转动以及带动磁性件21转动。由于磁性件21发生转动,则磁感应件2与磁性件21相对位移,从而使得磁感应件2产生感应电流。As shown in FIGS. 6 and 8 , the driving
具体地,如图5、图6和图8所示,磁性件21转动时会产生变化的磁场,磁感应件2切割磁场以产生感应电动势E,即磁感应件2切割磁场以产生感应电流,换言之,磁感应件2切割磁场中的磁力线以产生感应电流,其中,感应电流为交变电流。Specifically, as shown in FIG. 5, FIG. 6 and FIG. 8, when the
作为一种可选方案,如图5和图8所示,驱动电路4包括整流滤波电路,消电件1为LED。则驱动电路4对感应电流进行整流滤波处理,生成供电电压VCC,其中,供电电压为直流供电电压。驱动电路4通过供电电压VCC为消电件1提供电力,从而实现磁感应件2通过驱动电路4向消电件1输出感应电流。具体地,如图8所示,驱动电路4、限流电阻R与消电件1串联连接,驱动电路4输出供电电压VCC,并通过限流电阻R向消电件1供电,从而实现磁感应件2通过驱动电路4向消电件1输出感应电流,以驱动消电件1发光。As an optional solution, as shown in FIG. 5 and FIG. 8 , the driving
此外,驱动电路4还可包括放大电路和/或稳压电路,能够对电流进行放大、稳压。In addition, the
如图5、图6和图9所示,感光鼓20转动一圈后,磁感应件2产生的感应电动势E的个数n为a×b,其中,a为磁感应件2的个数,b为磁性件21的个数。驱动电路4对磁感应件2产生的a×b个感应电动势E进行整流处理后得到2a×b个感应电动势E,而后驱动电路4对2a×b个感应电动势E进行滤波处理得到供电电压VCC。单位时间内感应电动势E的个数越多,则滤波处理后输出的供电电压VCC越稳定。感应电动势E由磁感应件2的单位时间内的磁通量变化量决定,即:E=△Q/△t,其中,△Q为磁通量变化量,△Q与磁性件21的磁极强度和感光鼓20的转速相关。磁通量变化量△Q与感光鼓20的转速成正比,因此,感应电动势E与感光鼓20的转速成正比,即:感应电流与感光鼓20的转速成正比,感光鼓20的转速越快,则感应电动势E(感应电流)越大,消电件1的出射光的光强越强,出射光的亮度越高。也就是说,消电件1的发光亮度与感光鼓20的转速成正比。例如,感光鼓20的转速越快,消电件1的发光亮度越高,则对感光鼓20外表面的残存电荷进行消电的速度越快;或者,感光鼓20的转速变慢(例如,图像形成装置处于间歇打印模式或者静音打印模式),消电件1的光强随着感光鼓20转速变慢而降低,则对感光鼓20外表面的残存电荷进行消电的速度也降低。因此,消电件1的光强随着感光鼓20的转速而变化,实现了消电件1的亮度可控。从而实现了感光鼓20的转速与消电程度的匹配,有效防止了消电件对感光鼓20的过度消电或者对感光鼓20的消电不充分,进而使得消电件与感光鼓实现了匹配消电。As shown in Fig. 5, Fig. 6 and Fig. 9, after the

如图5所示,消电件1发出的光线照射至感光鼓20的感光表面,以对感光鼓20的外表面的残存电荷进行消电。消电件1发出的光线照射至聚光件302,聚光件302将光线汇聚至导光条301,导光条301对光线进行导光以使光线照射到感光鼓20的外表面,并且反射件303可将导光条301发出的多余的光线反射回导光条301,使得导光条301能够将多余的光线也照射到感光鼓20上,感光鼓20的外表面受到光照后残存电荷被均匀导走,从而实现了对感光鼓20外表面的残存电荷进行消电。As shown in FIG. 5 , the light emitted by the dissipating
本发明实施例提供的技术方案中,磁感应件与磁性件相对位移以使磁感应件产生感应电流,消电件接收感应电流并启动,消电件对感光鼓的外表面的残存电荷进行消电,无需额外配置电源即可使得消电件对感光鼓消电,从而减小了消电件的占用空间,且消电件的结构简单,采用了无源设计,无需外部供电;磁感应件与磁性件相对位移时,磁感应件产生感应电流,以驱动消电件消电,因此,消电件的消电程度随着磁感应件与磁性件相对位移的速度而变化,从而实现了磁感应件与磁性件相对位移的速度与消电程度的匹配,有效防止了消电件对感光鼓的过度消电或消电不充分的现象,进而使得消电件与感光鼓实现了匹配消电。In the technical solution provided by the embodiment of the present invention, the magnetic induction part and the magnetic part are relatively displaced so that the magnetic induction part generates an induced current, and the current elimination part receives the induced current and starts, and the current elimination part eliminates the residual charge on the outer surface of the photosensitive drum, The power dissipating part can dissipate electricity to the photosensitive drum without additional power supply, thereby reducing the occupied space of the dissipating part, and the structure of the dissipating part is simple, adopting a passive design, and no external power supply is required; the magnetic induction part and the magnetic part During the relative displacement, the magnetic induction part generates an induced current to drive the current elimination part to eliminate electricity. Therefore, the degree of electricity elimination of the current elimination part changes with the relative displacement speed of the magnetic induction part and the magnetic part, thus realizing the relative displacement between the magnetic induction part and the magnetic part. The matching of the displacement speed and the degree of de-energization effectively prevents the phenomenon of excessive or insufficient de-energization of the photosensitive drum by the de-energizer, and then realizes matching de-energization of the de-energizer and the photosensitive drum.

本发明实施例的技术方案中,磁感应件产生的感应电流与感光鼓的转速成正比,则消电件的光强与感光鼓的转速成正比,因此,消电件的光强与感光鼓的转速匹配,从而使得消电件与感光鼓的暗衰曲线也可以匹配,使得感光鼓的外表面可以有效消电,进而提高了感光鼓的充放电能力,防止出现重影以及过充过放等疲劳现象,延长了感光鼓的寿命。In the technical solution of the embodiment of the present invention, the induced current generated by the magnetic induction element is proportional to the rotation speed of the photosensitive drum, and the light intensity of the current elimination element is proportional to the rotation speed of the photosensitive drum. Therefore, the light intensity of the electricity elimination element is proportional to the rotation speed of the photosensitive drum. Speed matching, so that the dark decay curve of the power dissipating part and the photosensitive drum can also match, so that the outer surface of the photosensitive drum can effectively dissipate electricity, thereby improving the charge and discharge capacity of the photosensitive drum, preventing ghosting and overcharging and overdischarging, etc. Fatigue phenomenon, prolonging the life of the photosensitive drum.
本发明实施例的技术方案中,通过无源消电件和导光条实现了对感光鼓的外表面进行消电,减少了感光鼓外表面的残存电荷,减少了光疲劳,从而避免了打印过程出现的重影现象,提升了打印画像质量。In the technical solution of the embodiment of the present invention, the external surface of the photosensitive drum is eliminated by the passive electricity dissipating parts and the light guide strip, which reduces the residual charge on the outer surface of the photosensitive drum, reduces light fatigue, and thus avoids printing The ghosting phenomenon that occurs during the process improves the quality of the printed image.
