技术领域
本发明涉及激光打印领域，尤其是涉及一种激光签注系统及其签注方法。
背景技术
证卡，用来证明身份、经历等的证书和文件，如身份证、驾驶证等个人证件。身份证、驾驶证以及护照等证件上的个性化信息，如人物头像、姓名、年龄等，需要采用打印机进行打印。待打印的证卡一般包括有两个打印面，分别为正打印面和反打印面。
激光打印系统是一种常用的证卡打印设备，其一般包括控制系统及与控制系统通讯连接的打印机台和激光打印装置，其中：打印机台用于承载待打印证卡，激光打印装置按控制系统发出的打印指令将目标打印信息打印至待打印证卡的当前打印面上。
在一些的打印实践中，待打印证卡的正打印面和反打印面上均预印有特定的公共模板信息。激光打印系统需要在证卡的正打印面、反打印面的预定区域打印出与公共模板信息相匹配的打印信息(即个性化信息)，所述公共模板信息和所述打印信息则构成打印后的完整的卡面信息。当然，所述公共模板信息、所述打印信息均可包括文字和/图像。
现有的激光打印系统，其存在如下缺陷：(1)激光打印装置位于翻转装置的上方，翻转装置作为打标位，其结构会出现传输不稳定、打滑、卡片发生卡在装置内的情况；(2)证卡在签注的过程中进行拍照，由于翻转装置的导向轮等其他设置，多少对证卡表面有遮挡，无法实现对卡片表面的无遮挡拍照、全景拍照，对卡片的识别、检验有一定影响；(3)激光打印装置由于外部震动不稳定，准确性和精度较低，且外部光线干扰激光光源，使得拍照的照片出现明暗不同，亮度不均；(4)激光打印系统采用相机进行定位，相机需要卡片减速、拍照、识别，因此卡片传输、定位的速度慢。
因此，有必要提供一种新的技术方案。

在图5至图8示的实施例中，所述第二传感器950设置于所述打印及拍照联合机台90”上证卡原向移出的一端。当所述第二传感器950检测到证卡的原向平移到达打标位时，即所述第二传感器检测到证卡的原向平移达到打印及拍照位置。所述第一传感器940检测所述若干第一平移上传动轮931和所述若干第二平移上传动轮933是否翻转到位，即检测所述若干第一平移上传动轮931和所述若干第二平移上传动轮933是否翻转至打印及拍照位置。例如，当所述第一传感器940检测到若干第一平移上传动轮931和若干第二平移上传动轮933翻转至打印及拍照位置时，其输出翻转到位信号。
在图7和图8所示的具体实施例中，所述第一传感器940包括挡板942和光电感应器(未图示)。所述挡板942设置于所述第一转轴921上，所述光电感应器位于所述第一拍照侧板914的外侧且靠近所述第一转轴921。当所述第一转轴921带动若干第一平移上传动轮931转离打印及拍照位置时，所述挡板942翻转至所述光电感应器外，所述光电感应器中的发射接收光路畅通，使所述第一传感器940产生第一传感信号；当所述第一转轴921带动若干第一平移上传动轮931翻转至打印及拍照位置时，所述挡板942翻转至所述光电感应器中，以阻挡所述光电感应器中的发射接收光路，使所述第一传感器940产生第二传感信号(即所述翻转到位信号)。
所述摄像装置50位于所述打印及拍照联合机台90”的拍照机架910上方，所述摄像装置50用于对承载于所述拍照机架910的传输通道912中的证卡100进行拍照。
为了便于理解本发明，以下具体介绍图1至图8所示的打印及拍照联合机台的工作过程。
当证卡100需要平移至预定打印及拍照位置时，所述若干第一平移上传动轮931和若干第二平移上传动轮933均处于初始位置(请参阅图8)。若干第一平移上传动轮931垂直于所述证卡方向放置，且第一平移上传动轮931与其相对的所述第一平移下传动轮932之间形成有平移间隙，以夹持证卡100的一侧并驱动证卡平移；若干第二平移上传动轮933垂直于所述证卡方向放置，且第二平移上传动轮933与其相对的所述第二平移下传动轮934之间形成有平移间隙，以夹持证卡100的另一侧并驱动证卡平移。此时，所述平移上传动轮931、933和平移下传动轮932、934起到传送证卡100的作用。
当证卡100沿传输通道921平移至预定打印及拍照位置需要打印和拍照时，所述第三转轴923向第二转动方向转动，经由所述第三齿轮9232和第一齿轮9212带动所述第一转轴921转动，以使若干第一平移上传动轮转931翻转至打印及拍照位置，经由第四齿轮9234和第二齿轮9222带动所述第二转轴922转动，以使若干第二平移上传动轮933 翻转至打印及拍照位置。若干第一平移上传动轮931平行于所述证卡方向放置，以使所述若干第一平移上传动931避开所述证卡100；若干第二平移上传动轮933平行于所述证卡方向放置，以使所述若干第二平移上传动轮933避开所述证卡100。也就是说，当处于预定打印及拍照位置的证卡需要打印和拍照时，所述若干第一平移上传动轮931和所述若干第二平移上传动轮933被打开。此时，所述挡板942进入光电感应器944中，所述传感器940产生并输出翻转到位信号。随后，位于所述拍照机架910上方的摄像装置50对位于预打印及拍照位置处的证卡100进行拍照，所述激光打印装置对证卡进行打印。
当拍照和打印完成后证卡100需要平移以离开预定打印及拍照位置时，所述第三转轴923向第一转动方向转动(所述第一转动方向与所述第二转动方向相反)，经由所述第三齿轮9232和第一齿轮9222带动所述第一转轴921转动，以使若干第一平移上传动轮931翻转至初始位置，经由第四齿轮9234和第二齿轮9222带动所述第二转轴922转动，以使若干第二平移上传动轮933翻转至初始位置。也就是说，当证卡需要平移以到达或离开所述预定拍照及打印位置时，所述若干第一平移上传动轮931和所述若干第二平移上传动轮933被复位(或闭合)。随后，所述平移模块930将所述证卡100沿原向或反向传送出。
请参阅图5，所述证卡翻转机台30”包括平移机构和翻转机构。所述平移机构被配置的驱动证卡平移；所述第四传感器340和第五传感器350被配置的配合检测证卡是否处于预定平移位置，即所述第四传感器340被配置的检测当前证卡的平移前端是否超出证卡翻转机台30”；所述第五传感器350被配置的检测当前证卡的平移后端是否超出证卡翻转机台30”。所述翻转机构被配置的翻转证卡以将证卡的当前打印面由第一打印面翻转为第二打印面。所述第三传感器330被配置的用来检测证卡翻转是否处于预定翻转位置，即所述第三传感器330被配置的检测当前证卡的翻转是否水平。需要说明的是，本实施例中，所述第二传感器950、第三传感器330、第四传感器340和第五传感器350的检测原理同第一传感器940，在此不做赘述。
本发明采用多个传感器进行定位，定位速度快，签注效率高。
请参阅图2，所述证卡翻转机台30”的平移机构包括若干组压轮，每组压轮包括上压轮31和下压轮(未图示)，所述上压轮31和下压轮之间设置有供证卡通过的间隙，所述压轮与证卡的接触面积小于或等于读写卡装置的传动轮21与证卡的接触面积。本发明中的证卡翻转机台不是打标位，平移机构的采用上压轮和下压轮，且压轮位于中心的结构，压轮较宽，与证卡接触面积大，能够更稳定的传送证卡及翻转证卡，不会发生打滑、证卡被卡在装置内的情况。
下面介绍本发明的激光签注系统的工作流程：
在进行单面打印时，证卡100通过自动发卡装置10快速发卡至打印及拍照联合机台90”，打印及拍照联合机台90”的平移模块930正向转动带动证卡100平移，证卡 100平移前端到第二传感器950的位置，当第二传感器950检测到证卡到达打印及拍照位置到位后，转轴驱动电机926工作，通过边上的转轴驱动主动轮带动第三转轴923一端的转轴驱动从动轮925转动，第三转轴923转动带动第三转轴923两端的第三齿轮9232和第四齿轮9234转动，第三齿轮9232和第四齿轮9234分别带动第一齿轮9212和第二齿轮9222转动，随着第一齿轮9212和第二齿轮9222的转动，第一转轴921和第二转轴922向外旋转打开，使第一平移上传动轮931和第二平移上传动轮933打开，第一平移上传动轮931和第二平移上传动轮933由原来垂直证卡100的方向变为平行证卡100的方向，此时由摄像装置50进行拍照，激光打印装置60进行第一面的打标，拍照和打标完成后，使第一平移上传动轮931和第二平移上传动轮933再恢复至初始位置，将证卡100沿原向传送出。需要说明的是，在另一个实施例中，激光打印装置60进行第一面的打标，拍照和打标完成后，还可以再次进行拍照进行校验，校验之后，使第一平移上传动轮931和第二平移上传动轮933再恢复至初始位置，将证卡100沿原向传送出。
在进行双面打印时，单面打印完成后，打印及拍照联合机台90的第一平移上传动轮931和第二平移上传动轮933再恢复至初始位置，将证卡100沿反向传送至证卡翻转机台30”，此时，所述证卡翻转机台30”的平移机构反向转动，使得当证卡末端(证卡反向平移前端)到达第四传感器340的位置，且证卡前端(证卡反向平移后端)不超过第五传感器350，即此时证卡是位于证卡翻转机台的通道内，证卡翻转机台30”的翻转机构开始翻转，当第三传感器330检测到当前证卡翻转处于水平位置时，证卡翻转机台的平移机构正向转动，将证卡继续正向运动至打印及拍照联合机台90”的打印及拍照位置处，进行第二面的打标、拍照，最后原向通过自动出卡装置80出卡。
需要说明的是，如上所述的实施例中，所述激光签注系统的读写卡装置20和证卡翻转机台30”的位置可以互换。
在另一实施例中，本发明还提供一种激光签注方法，其使用激光签注系统对证卡的第一打印面和第二打印面进行连续激光打印，所述激光签注系统包括控制系统及分别与所述控制系统通讯连接的打印及拍照联合机台、证卡翻转机台30”、第二传感器950、第三传感器330、第四传感器340、第五传感器350、激光打印装置60和摄像装置50，所述激光签注方法包括：
控制系统获取待打印信息。
打印及拍照联合机台90”的平移模块将待打印的证卡100进行原向平移，所述第二传感器950检测待打印的证卡是否到达预定打印及拍照位置。
若待打印的证卡到达预定打印及拍照位置，所述摄像装置50获取当前第一打印面的图像并将图像发送给所述控制系统，所述控制系统对第一打印面的图像进行识别以判断所述第一打印面的类型及方向；并将与所述当前的第一打印面的类型和方向相匹配的第一打印信息模板发送给所述激光打印装置，所述激光打印装置在所述第一打印面上打 印出与所述第一打印信息模板相对应的图案和/或文字。
打印及拍照联合机台90”的平移模块将第一打印面打印完成的证卡反向平移至证卡翻转机台30”。
所述证卡翻转机台的第四传感器340检测当前证卡反向平移前端是否超出证卡翻转机台，所述第五传感器350检测当前证卡的反向平移后端是否超出证卡翻转机台，若当前证卡的反向平移前端和反向平移后端均未超出证卡翻转机台，所述翻转机构对证卡进行翻转以将证卡的当前的打印面翻转为第二打印面，所述第三传感器330检测翻转后的证卡是否水平，若是，则所述证卡翻转机台的平移机构将翻转后的证卡原向平移至打印及拍照联合机台90”。
所述控制系统基于所述第一打印面的类型及方向和所述翻转机构的翻转方式判断所述第二打印面的类型及方向，或所述摄像装置获取所述第二打印面的图像并将图像发送给所述控制系统，所述控制系统对第二打印面的图像进行识别以判断所述第二打印面的类型及方向，所述控制系统将与所述第二打印面的类型及方向相匹配的第二打印信息模板发送给所述激光打印装置，所述激光打印装置在所述第二打印面上打印出与所述第二打印信息模板相对应的图案和/或文字。
本发明具有如下有益效果：
(1)本发明的激光打印装置位于打印及拍照联合机台的上方，即打印及拍照联合机台为打标位，在同一工位既能实现对证卡的无遮挡拍照，同时实现对证卡进行签注。
(2)激光打印装置下方通过支架稳定地固定在工作台面上，激光打印装置不会由于外部的震动导致不稳定，提高激光打印的准确性和精确度；光源外部通过遮光板进行遮挡，不会与外部的光线相互影响。且激光光源从先前的条光源变改进为本发明的面光源，使得拍照得到的照片不会出现明暗不同的区域，照片亮度更为均一。
(3)证卡翻转机台不是打标位，平移机构采用上下两组压轮，且压轮位于中心的结构，压轮较宽，与证卡接触面积大，能够更稳定的传送证卡及翻转证卡。
(4)在打印及拍照联合机台的证卡传输通道两侧设置有挡条，挡条采用耐磨材料，且挡条可根据证卡的大小进行灵活更换，证卡传输通道间距精度高，更稳定地传送及定位证卡，且证卡经过后不会有磨损。
(5)本发明的激光签注系统采用多个传感器进行定位，定位速度快，签注效率高。
综上，本发明的激光签注系统的签注速度快、效率高、易于控制，且签注效果稳定性、准确性得到提高。
