如图1至图5所示，本申请实施例提供一种打印机，该打印机可以是光固化打印机，且该打印机包括底座10、光源模组20、光学折射镜30和屏幕40，光源模组20和光学折射镜30均设于底座10上，且光源模组20和屏幕40均对应光学折射镜30设置；
其中，光学折射镜30的折射面为内凹型曲面，光源模组20包括集成设置的发光件21和透镜22，发光件21发射的光线穿过透镜22后转换成发射角度固定且能量均匀的光线，且穿过透镜22的光线射向光学折射镜30，并经光学折射镜30折射后垂直射向屏幕40。
本实施方式中，通过采用包括集成设置的发光件21和透镜22的光源模组20，以使光源模组20能够发射出发射角度固定且能量均匀的光线，且光源模组20发射的光线经内凹型曲面的折射面折射后，可以转换成垂直射向屏幕40的光线，即使得光源模组20发射的光线可以垂直射向屏幕40，进而达到提高射向屏幕40的光线的垂直度的目的。
而且，由于光源模组20射出的光线还具有能量均匀的特性，从而改善射向屏幕40的光线的能量偏差的问题，并达到提高打印机的打印精度和打印效果的目的。
可以理解的是，屏幕40可以是LCD屏幕，并用于透光和显示打印图像。
如图3和图4，光学折射镜30的内凹型曲面可以是内凹型球面或者内凹型椭球面，且其内凹参数与透镜22的光学参数相关联，即可以根据透镜22的光学参数设置内凹型曲面的内凹参数。
如图2所示，将经由透镜22射出的光线定义为A类光线，即发光件21发射的光线穿过透镜22后可以转换成A类光线，即转换成发射角度固定且能量均匀的光线；以及，将经由光学折射镜30折射后的光线定义为B类光线，即A类光线经由光学折射镜30折射后，会转换成B类光线，即可以转换成垂直射向屏幕40的光线，从而达到提高射向屏幕40的光线的垂直度的目的。
其中，屏幕40的打印面积由光源模组20在屏幕40上的照射范围确定，且光源模组20距离屏幕40的距离越远，光源模组20在屏幕40上的照射范围越大。比如，在屏幕40的打印面积设置为S的情况下，即光源模组20在屏幕40上的照射范围设置为S的情况下，则需要将光源模组20和屏幕40之间的间距设置为L，以便满足打印机的打印需求。
本申请中，由于光源模组20射出的光线需经光学折射镜30折射，因此光线在光源模组20和屏幕40之间的传输路径被分成两段，即折射前的传输路径段和折射后的传输路径段，即自光源模组20射出的光线分成了A类光线和B类光线，且A类光线的传输路径长度和B类光线的传输路径长度之和需要等于L，以便满足打印机的打印需求。
如图2所示，A类光线的轮廓线的长度为L1，B类光线的轮廓线的长度为L2，即L1和L2的和值需要等于L，以满足打印机的打印需求。
另外，还可以根据打印机的尺寸要求，灵活设置L1、L2的数值，以满足实际设计需求。 比如，需要设置低矮型打印机的情况下，则可以减小L2的数值，进而达到降低打印机高度的目的。
在制备光学折射镜30的过程中，可以先提供一板材，然后在板材上形成内凹型曲面，最后在内凹型曲面上设置光学反射层，以得到光学折射镜。其中，光学反射层可以电镀的方式沉积在内凹型曲面上。
可选地，如图5所示，光源模组20还包括基板23和透镜固定座24，基板23包括相背设置的第一表面(未图示)和第二表面(未图示)；
其中，透镜22通过透镜固定座24设于第一表面上，发光件21设于第一表面上并位于透镜22和第一表面之间。
本实施方式中，透镜固定座24可以罩设于第一表面上，且透镜固定座24和第一表面之间可以形成一容置腔，发光件21可以位于容置腔内，以实现发光件21和透镜22的集成设置。
一示例中，透镜固定座24为遮光材料制成，或者透镜固定座24的内表面或外表面设于遮光层，以避免发光件21发射的光线从除透镜22之外的其他方向射出，并达到改善光源模组20的发光效果的目的。
可选地，发光件21包括芯片基板211和发光芯片212，发光芯片212通过芯片基板211设置在第一表面上，且发光芯片212发射的光线穿过透镜22后转换成发射角度固定且能量均匀的光线。
本实施方式中，发光芯片212可以是矩阵光源芯片，比如COB光源芯片，以使发光件21发射的光线具有发射角度固定且能量均匀的特性。
可以理解的是，本申请中的光源模组20发射的光线可以是紫外光线。
另外，发光件21还可以包括芯片基座213，发光芯片212设置在芯片基板211上，芯片基板211设置在芯片基座213上，芯片基座213设置在第一表面上。
而且，光源模组20还可以包括散热片25，散热片25设于第二表面上，散热片25用于降低发光件21处的温度，避免发光件21出现过热的问题。
可选地，打印机还包括滑座50，光源模组20通过滑座50与底座10连接，且滑座50与底座10滑动连接。
本实施方式中，通过设置滑座50，可以调整光源模组20与光学折射镜30之间的间距，进而调整光学折射镜30的射向屏幕40的覆盖面积，即调整打印机的打印区域。
比如，光源模组20距离光学折射镜30的距离越远，光学折射镜30的射向屏幕40的覆盖面积越大，即打印机的打印区域越大；而光源模组20距离光学折射镜30的距离越近，光学折射镜30的射向屏幕40的覆盖面积越小，即打印机的打印区域越小；进而实现打印机的打印区域的灵活调整。
可选地，打印机还包括第一限位柱61，底座10上设有与第一限位柱61适配的第一限位孔(未图示)，第一限位柱61装配于第一限位孔内；
其中，滑座50可沿第一限位柱61相对底座10移动。
本实施方式中，通过设置第一限位柱61，可以避免滑座50在移动过程中出现偏移， 即光源模组20的移动精度，进而达到提升打印机的打印进度的目的。
可选地，打印机还包括固定座70，光学折射镜30通过固定座70设置在底座10上；
其中，固定座70与底座10可拆卸连接，光学折射镜30与固定座70卡接。
本实施方式中，通过固定座70将光学折射镜30设置在底座10上，可以提升光学折射镜30与底座10的连接的稳定性。
其中，固定座70和底座10之间可以通过螺栓固定连接；光学折射镜30上可以设置卡条(未图示)，固定座70上可以设置与卡条适配的卡槽(未图示)，并通过卡条与卡槽的卡接，将光学折射镜30固定在固定座70上。
可选地，打印机还包括第二限位柱62，底座10上设有与第二限位柱62适配的第二限位孔(未图示)，第二限位柱62装配于第二限位孔内，且第二限位柱62用于限定固定座70在底座10上的安装位置。
本实施方式中，通过设置第二限位柱62，可以提高固定座70在底座10上的安装精度，并提高光学折射镜30的折射效果。
可选地，打印机还包括固定板80，屏幕40设置在固定板80上；
打印机还包括设备主体(未图示)，底座10和固定板80均设置在设备主体上。
可选地，如图1所示，光源模组20和光学折射镜30位于底座10和屏幕40之间，光学折射镜30在第一平面上的正投影与屏幕40在第一平面上的正投影至少部分重合，光源模组20在第一平面上的正投影与屏幕40在第一平面上的正投影间隔设置；
其中，第一平面为底座10在承载面所在的平面。
本实施方式中，通过将光源模组20、光学折射镜30和屏幕40非同轴摆放，即将光源模组20、光学折射镜30和屏幕40错位摆放，尤其是将光源模组20和屏幕40错位摆放，可以缩短光源模组20到屏幕40之间的直线距离，进而降低打印机的整体高度，满足打印机的小型化发展趋势。
一示例中，光源模组20和光学折射镜30可以均设置在底座10的承载面上。
如图2所示，可以将光学折射镜30设于屏幕的正下方，以及将光源模组20设于光学折射镜30的折射面的正前方，以将光源模组20到屏幕40之间的光学传导路径拆分两段，即折射前的传输路径段L1和折射后的传输路径段L2，并使L1和L2的和值等于光源模组20到屏幕40之间的直线距离，从而降低打印机的整体高度，满足打印机的小型化发展趋势。，
而且，通过这样设置，可以提高光学折射镜30的射向屏幕40的覆盖面积，进而提高打印机的打印区域的大小。
