Description

进卡装置和具有该进卡装置的证卡打印机 技术领域
本发明涉及证卡打印机技术领域，尤其涉及进卡装置和具有该进卡装置的证卡打印机。
背景技术
证卡打印机是用来进行证件打印的设备，在日常工作生活中我们看到的各种印有照片的胸卡或证件就是它的产物，证卡打印机在打印时需要将堆叠的卡片分离后单张送入，在此过程中起关键作用的就是其内部的进卡装置。
现有证卡打印机的进卡装置通常利用滚轮摩擦力将卡片向出卡口运送，由于卡片堆叠放置在进卡装置的底座上，卡片之间的静电吸附力较大，滚轮的摩擦力极有可能不足以使底层的卡片分离，导致于进卡失败，证卡打印机经常停机故障，严重影响使用体验。
因此，如何设计进卡成功率高的进卡装置是业界亟待解决的技术问题。
发明内容
为了解决现有进卡装置易出现进卡失败等缺陷，本发明提出进卡装置和具有该进卡装置的证卡打印机，该进卡装置采用旋转进卡机构搭配滚轮进卡机构来带动进卡，可兼顾进卡成功率和进卡速度。
本发明采用的技术方案是，设计进卡装置，包括：
底座，其用于堆叠放置卡片，底座的一端设有出卡口；
旋转进卡机构，其位于最底层卡片的下方，旋转进卡机构具有旋转摆臂和设于旋转摆臂上的推杆，推杆随旋转摆臂转动时将最底层卡片推向出卡口；
滚轮进卡机构，其安装在旋转进卡机构和出卡口之间，滚轮进卡机构具有外缘凸出底座顶面的滚轮，滚轮转动时将最底层卡片向出卡口运送。
优选的，底座上设有容纳旋转摆臂转动的旋转槽，旋转槽的深度连续变化且与旋转摆臂的转动轨迹相匹配，旋转槽上距离出卡口最远的第一极限位置的深度最小，旋转槽上距离出卡口最近的第二极限位置的深度最大；
推杆旋转到第一极限位置时，推杆上升至露出底座的顶面；
推杆旋转到第二极限位置时，推杆下沉至位于底座的顶面之下。
优选的，旋转进卡机构还具有旋转台，旋转摆臂的中部铰接在旋转台上，旋转摆臂上设置有推杆的一端为勾卡端，旋转摆臂的另一端为调节端；
勾卡端向第一极限位置旋转时，旋转槽逐渐向上托起勾卡端；
调节端向第一极限位置旋转时，旋转槽逐渐向上托起调节端，以使勾卡端下沉。
优选的，旋转进卡机构还具有固定在旋转台底部的蜗轮和与蜗轮啮合的蜗杆，蜗杆的一端穿出底座以作为传动端，传动端由动力机构驱动旋转。
优选的，传动端固定套有外圈与动力机构传动连接的单向轴承，动力机构转动时通过单向轴承的反向阻力带动传动端旋转。
优选的，滚轮固定在与其同轴设置的转轴上，转轴的一端穿出底座以作为旋转端，旋转端由动力机构驱动旋转。
优选的，旋转端固定套有外圈与动力机构传动连接的单向轴承，动力机构传动时通过单向轴承的反向阻力带动旋转端旋转。
优选的，单向轴承的外圈固定套有从动齿轮，动力机构具有马达，马达的输出轴上固定套有与从动齿轮啮合的主动齿轮。
优选的，滚轮的外缘包覆有用于增加摩擦力的胶层。
本发明还提出了证卡打印机，其包括上述的进卡装置。
与现有技术相比，本发明整合两种进卡方式来进卡，利用旋转进卡机构分离底层卡片并向出卡口推送，以提高进卡成功率，利用滚轮进卡机构将卡片进一步向出卡口运送，以提高进卡速度。
附图说明
下面结合实施例和附图对本发明进行详细说明，其中：
图1是本发明中旋转摆臂转动至旋转槽中间位置的示意图；
图2是本发明中旋转摆臂转动至第二极限位置的示意图；
图3是本发明中进卡装置的结构示意图。
具体实施方式
如1至3所示，本发明提出的进卡装置适用在打印机等设备中，尤其适合用在证卡打印机中。进卡装置包括：底座1、旋转进卡机构和滚轮进卡机构，底座1的两侧各安装有一个侧板12，底座1的一端设有连接在两个侧板12之间的挡板13，侧板12和挡板13之间围成一个存放腔，卡片3堆叠放置在该存放腔中，挡板13与底座1的顶面预留有间距形成出卡口，假设单张卡片3的厚度为L，该间距大于L且小于2L，以防止两张卡片3被同时推出。为了更好的定位卡片3，在实际应用中可以将存放腔的尺寸设计为与卡片3间隙配合。
旋转进卡机构位于最底层卡片3的下方，旋转进卡机构包括：旋转台6、旋转摆臂8和推杆9，底座1内设有安装旋转台6的空腔，旋转摆臂8的中部铰接在旋转台6上，推杆9设置在旋转摆臂8的一端上，该端作为旋转摆臂8的勾卡端，旋转摆臂8的另一端为调节端7，旋转摆臂8的中部设有一对耳片，旋转台6上设有位于该对耳片之间的支撑部，铰接轴穿过该对耳片和支撑部，旋转摆臂8安装完成后呈跷跷板的状态。
底座1上还设有容纳旋转摆臂8转动的旋转槽11，旋转槽11从俯视方向看呈圆形，旋转槽11的深度连续变化，并且深度与旋转摆臂8的旋转轨迹相匹配。更详细的说，旋转槽11中设有位于旋转摆臂8下方的弧形凸筋110，弧形凸筋110的高度连续变化从而使得旋转槽11的深度连续变化，弧形凸筋110上高度越高的位置，旋转槽11相对于旋转摆臂8的深度越小，弧形凸筋110上高度越低的位置，旋转槽11相对于旋转摆臂8的深度越大，旋转槽11上距离出卡口最远的第一极限位置深度最小，即弧形凸筋110上对应的位置高度最大，旋转槽11上距离出卡口最近的第二极限位置深度最大，即弧形凸筋110上对应的位置高度最小。
旋转进卡机构还包括固定在旋转台6底部的蜗轮和与蜗轮啮合的蜗杆5，蜗杆5的一端穿出底座以作为传动端，传动端由动力机构驱动旋转，蜗杆5转动时驱动蜗轮转动，为了使传动更精确，蜗轮和旋转台6同轴设置，旋转摆臂8的中部即铰接位置恰好位于该旋转台6的轴线上。
如图1、2所示，旋转台6转动时，推杆9随旋转摆臂8一起转动，勾卡端逐渐向第一极限位置转动，旋转槽11的深度逐渐减小(对应于弧形凸筋110的高度逐渐增大)，以将勾卡端向上托起，推杆9逐渐露出底座1的顶面，运动到第一极限位置时推杆超出底座1顶面的高度最大，超出的高度不能超过单张卡片3的厚度L，以防止推杆9继续运动时将最底层的两张卡片3同时推出。推杆9转动到第一极限位置时，卡片3位于其与出卡口之间，继续转 动旋转台6，推杆9随旋转摆臂8一起转动，勾卡端逐渐向第二极限位置转动、调节端逐渐向第一极限位置转动，弧形凸筋110逐渐向上托起调节端7，调节端7翘起以迫使勾卡端下沉，勾卡端转动过程中推杆9推动最底层卡片3的边缘，使其脱离其上方堆叠的卡片3向出卡口运动，勾卡端运动到第二极限位置时，调节端7和推杆9均不超过底座1的顶面，防止运动过程中伤害卡片3表层。在优选实施例中，勾卡端的重量大于调节端7，勾卡端向第二极限位置转动时，旋转槽11的深度逐渐加大(对应于弧形凸筋110的高度逐渐减小)，在调节端7翘起和自身重力的共同作用下勾卡端自动下沉，旋转摆臂8两端的高低起伏运动更灵活顺滑。
如图3所示，滚轮进卡机构安装在旋转进卡机构和出卡口之间，滚轮进卡机构包括外缘凸出底座顶面的滚轮10，滚轮10转动时利用摩擦力将旋转进卡机构推出的最底层卡片3继续向出卡口运送，提高进卡效率。进一步优化的，滚轮10的外缘包覆有胶层，该胶层的作用不仅可以增加摩擦力，还可以保护卡片3表层，防止滚轮刮伤卡片3。
滚轮进卡机构包括与滚轮10同轴固定的转轴，转轴的一端穿出底座1以作为旋转端，旋转端由动力机构驱动旋转，转轴旋转时驱动滚轮10转动，滚轮10与其上方的卡片3底面接触，将其向出卡口运送。
再进一步的，为了使结构紧凑，旋转进卡机构和滚轮进卡机构共用动力机构，具体结构如下，传动端与动力机构之间设有第一单向轴承4，第一单向轴承4的内圈固定套在传动端上。旋转端与动力机构之间设有第二单向轴承2，第二单向轴承2的内圈固定套在旋转端上。两个单向轴承的外圈均固定套有从动齿轮，动力机构包括马达和固定套在马达的输出轴上的主动齿轮，两个从动齿轮均与主动齿轮啮合，动力机构传动时通过单向轴承的反向阻力带动对应的传动端和旋转端旋转。
当然，实际应用时也可以采用两个马达分别驱动旋转进卡机构和滚动进卡机构运行，本发明对此不作限制。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
