Description

一种随动定焦系统
本申请要求于2014年12月29日提交中国专利局、申请号为201410848643.1、发明名称为“一种随动定焦系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及显微成像领域，尤其涉及一种随动定焦系统。
背景技术
在显微成像中，显微镜通过物镜对样品板进行放大成像，样品板上有多个样本，在一个样本测试完成之后需要移动样品板、使物镜对准另一个样本，以便对另一个样本进行放大成像，在对各个样本进行测试时需要保证样本板与物镜之间的距离不变，即各个样本成像工作距离不变。
但安装样本板的移动平台本身加工工艺导致移动平台是有平面度误差的，移动平台与样本板安装时也存在平面度误差，样品板本身也具有平面度误差，所以当样品板一个样本A点移动到另一个样本B点时，会出现A点和B点不在同一平面的问题，导致样本A点和样本B点的成像距离改变，从而导致偏离最佳焦距的情况。
为此现有技术中一般通过以下方法来解决偏离最佳焦距的问题。
第一种方法为显微镜制造厂家提高加工和装配的精度，让样品板和移动平台的平面度误差减到最小，但加工和装配工艺的提高有其极限，不容易达到。
第二种方法为显微镜有调焦结构，当出现脱焦的时候，操作人员可以根据经验自己再微调焦距，但这会导致成像操作操作复杂、效率较低且主观干扰影响成像效果。
第三种方法为采用红外测距、光栅测距等智能自动调焦系统，或者 图像识别自动调焦系统等自动调焦系统，但这样的系统通常包含精确的测距系统、PLC控制系统、电机驱动系统、图像分析系统等，系统复杂、造价高昂、稳定性和适应性较差。
因此现在需要提供一种结构简单的、造价低、稳定性好的方案，以便解决样品随移动平台移动而造成的焦距偏离的问题。

本发明提供了一种随动定焦系统，本系统中包括固定焦距装置，固定焦距装置的第二端与样品板接触，当样品板略有凸起时，固定焦距装置的第二端被样品板的凸起推动，导致观测装置也随凸起上移，由于物镜与固定焦距装置不发生变化，所以还能够维持物镜与样品板之间的距离不变，即成像距离不变。当样品板略有凹陷时，观测装置在自身重力作用下使固定焦距装置的第二端始终与样品板接触，维持物镜与样品板之间的成像距离不变。
本系统仅增加了一个固定焦距装置便可实现本发明的目的，并且固定焦距装置的结构简单、造价低、容易实现，且稳定性较好，能够解决样品成像随移动平台移动而造成的焦距偏离的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实 施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，本发明提供了一种随动定焦系统，包括：
承载平台400，固定于所述承载平台400上的样品板500，与所述承载平台400垂直连接的支撑架200，可滑动设置于所述支撑架200上的观测装置100，所述观测装置100包括相机或目镜101、物镜103和镜筒部102，一端与所述观测设置100固定相连，另一端与所述样品板500接触的固定焦距装置300，所述固定焦距装置300使所述样品板500与所述物镜103的垂直距离维持不变。
由于承载平台400和样品板500上不可避免的有平面度误差，因此本申请在观测装置100和样品板500之间加装固定焦距装置300，固定焦距装置300靠近样品板500的一侧为第二端，另一端为第一端，当物镜103与样品板500之间的成像距离、及固定焦距装置300的长度确定后，在固定焦距装置300第二端的末端与物镜103之间预留成像距离，然后将固定焦距装置300的第一端固定于观测装置100上。本申请中固定焦距装置300为刚性结构不易产生变形，因此能够维持固定焦距装置300的第二端末端与物镜103之间的成像距离不变。
固定焦距装置300的第二端与样品板500接触，当样品板500略有凸起时，固定焦距装置300的第二端被样品板500的凸起推动，导致观测装置100也随凸起上移，由于物镜103与固定焦距装置300不发生变化，所以还能够维持物镜103与样品板500之间的距离不变，即成像距离不变。当样品板500略有凹陷时，观测装置100在自身重力作用下使固定焦距装置300的第二端始终与样品板500接触，维持物镜103与样品板500之间的成像距离不变。
通过上述内容可知，本申请固定焦距装置300的末端与物镜103之 间的距离为成像距离，随着样品板500的凸起和凹陷，固定焦距装置300也会随着样品板500上移和下移，使得固定焦距装置300的末端始终与样品板500相接触，进而使得样品板500与物镜103之间的距离始终为成像距离。
一般情况下，观测装置100和固定焦距装置300的组合较为沉重，为了保护样品板500不会被观测装置100和固定焦距装置300的组合压碎，如图2所示，本申请还增加与所述支撑架200和所述观测装置100相连的、或与所述支撑架200和所述固定焦距装置300相连的弹力结构600，所述弹力结构600可支撑所述观测装置100和所述固定焦距装置300。
该弹力结构600能够支撑观测装置100和固定焦距装置300，具体来说是给观测装置100和固定焦距装置300一个向上的拉力，拉力与观测装置100和固定焦距装置300的重力平衡后，使得压迫样品板500的作用力较小，以便保护样品板500的完整性。
可使用的所述弹力结构600包括：机械弹力装置、气压弹力装置和/或液压弹力装置，弹力结构600的主要作用为给观测装置100和固定焦距装置300一个向上的拉力。下面结合图2详细说明弹力结构600的机械弹力装置部分：
如图2所示，弹力结构600包括：设置于所述支撑架200上的限位部件603，贯穿所述限位部件603的连接杆604，所述连接杆604的一端与所述观测装置100或固定焦距装置300固定相连，另一端设置有凸起601，套设于所述连接杆604上的弹簧602，所述弹簧602卡位于所述限位部件603与所述凸起601之间。
卡位于限位部件603和所述凸起601之间的弹簧602是预紧弹簧602，弹簧602上有预紧力，具体过程为：弹簧602的预紧力作用于限位部件603和凸起601之间，限位部件603固定不动、所以在预紧力的作 用下对凸起601有一个向上作用力，凸起601带动连接杆604对连接杆604有向上作用力，连接杆604与观测装置100相连，所以会带动观测装置100也有一个向上作用力。弹簧602预紧力小于或等于固定焦距装置300和观测装置100组合的重力，因为预紧力太大则会导致固定焦距装置300脱离样品板500而悬空，导致样品板500与物镜103之间的距离大于成像距离。
图1所示的装置仅能够在观测装置100正置时使用，当观测装置100倒置时观测装置100和固定焦距装置300由于重力作用向下移动，导致固定焦距装置300无法与样品板500接触，此时需要人为给观测装置100一个向上作用力，阻碍观测装置100和固定焦距装置300向下移动，使固定焦距装置300与样品板500始终接触。
但人为操作难免出现用力不均匀、或者无法保持固定焦距装置300与样品板500始终接触的目的，所以本发明在观测装置100倒置时，在原来结构上还增加了弹力结构600，如图3所示为观测装置100倒置时的结构图示。
承载平台400，固定于所述承载平台400上的样品板500，与所述承载平台400垂直连接的支撑架200，可滑动设置于所述支撑架200上的观测装置100，所述观测装置100包括相机或目镜101、物镜103和镜筒部102，一端与所述观测设置固定相连，另一端与所述样品板500接触的固定焦距装置300，所述固定焦距装置300使所述样品板500与所述物镜103的垂直距离维持不变，与所述支撑架200和所述观测装置100相连的、或与所述支撑架200和所述固定焦距装置300相连的弹力结构600，所述弹力结构600可支撑所述观测装置100和所述固定焦距装置300。
图3所示的装置与图1类似，仅在图1基础上还增加了弹力机构，弹力机构可包括：机械弹力装置、气压弹力装置和/或液压弹力装置。如 图3所示，详细介绍机械弹力装置，具体包括：
设置于所述支撑架200上的限位部件603，贯穿所述限位部件603的连接杆604，所述连接杆604的一端与所述观测装置100或固定焦距装置300固定相连、另一端设有凸起601，套设于所述连接杆604上的弹簧602，所述弹簧602卡位于所述限位部件603与观测装置100之间。
卡位于限位部件603和观测装置100之间的弹簧602也会预紧弹簧602，弹簧602预先设有预紧力，并且弹簧602的预紧力大于固定焦距装置300和观测装置100的组合，弹簧602的预紧力一端作用于限位部件603，另一端作用于测试装置，限位部件603固定不动，因此预紧力会对观测装置100有向上推动力，固定测试装置也会随着观测装置100一并有向上的推动力，从而使得固定测试装置与样品板500相接触。
图3中其他部件的作用与图1一致，在此不再赘述。
图2和图3中以连接杆604与镜筒部102相连，其实连接杆604与观测装置100相连具体可以为：所述连接杆604的一端与所述观测装置100的镜筒部102固定相连；或所述连接杆604的一端与所述观测装置100的物镜103相连；所述连接杆604的一端与所述观测装置100的相机或目镜101相连。即：连接杆604与观测装置100相连即可，因为连接杆604需要给观测装置100一个作用力，所以若两者不相连则无法传递作用力。
图1、图2和图3中示出了观测装置的镜筒部可滑动设置在支撑架上，当然还可以采用其他形式：所述观测装置100可滑动设置于所述支撑架200上具体为：
所述观测装置100的镜筒部102可滑动设置于所述支撑架200上；或
所述观测装置100的物镜103可滑动设置于所述支撑架200上；或
所述观测装置100的相机或目镜101可滑动设置于所述支撑架200 上。
如图1、图2和图3所示，所述镜筒部102包括：连接台1021和镜筒1022；
所述连接台1021一端与所述镜筒1022固定连接，另一端可滑动设置于所述支撑架200上。
下面详细介绍固定焦距装置300，固定焦距装置300可有多种实现形式，下面介绍三种，可以理解的是，其他可以固定焦距装置300的作用实现形式均是本发明的保护范围。
第一种：如图4所示，所述固定焦距装置300为支撑杆301，所述支撑杆301的一端与所述观测装置100固定相连，另一端与所述样品板500接触。
支撑杆301的方式简单、但也存在支撑不牢靠、固定不稳定的缺陷，因此本申请还提供了第二种方式。
第二种：所述固定焦距装置300为支撑杆301和透光部件302；所述支撑杆301的一端与所述观测装置100固定连接，另一端与所述透光部件302固定连接，所述透光部件302与所述物镜103相对的位置上中空。
固定焦距的第二端不是单纯的一个杆支撑，而是一个透光部件302支撑，为了防止样品板500的光路被阻挡，支撑部件为透明设置，方便入射光经过样品板500投射进来。并且为了防止透光部件302阻碍样本板与物镜103之间的成像通路，将透光部件302上与物镜103对应的位置上中空设置，以便物镜103与样品板500之间的成像通路不受透光部件302的影响。
第三种：第一种上采用一个支撑杆301的方式不太稳定，因此本方式中采用两个支撑杆301，在观测装置100的两旁各固定一个支撑杆301，且支撑杆301的长度一致，固定于观测装置100的位置均一致。这样便 可使得观测装置100均匀受力、较为稳定。
以上方式中，所述支撑杆301的一端与所述观测装置100固定连接具体为：
所述支撑杆301的一端与所述观测装置100的相机或目镜101固定相连；或
所述支撑杆301的一端与所述观测装置100的镜筒固定相连；和/或
所述支撑杆301的一端与所述观测装置100的物镜103固定相连。
以上仅是提供的三种可以实现的方式，可以理解的是，其他装置能够实现物镜103与样品板500之间成像距离不变的方式，均是本发明的保护范围。
本发明提供了一种随动定焦系统，本系统中包括固定焦距装置300，固定焦距装置300的第二端与样品板500接触，当样品板500略有凸起时，固定焦距装置300的第二端被样品板500的凸起推动，导致观测装置100也随凸起上移，由于物镜103与固定焦距装置300不发生变化，所以还能够维持物镜103与样品板500之间的距离不变，即成像距离不变。当样品板500略有凹陷时，观测装置100在自身重力作用下使固定焦距装置300的第二端始终与样品板500接触，维持物镜103与样品板500之间的成像距离不变。
本系统仅增加了一个固定焦距装置300便可实现本发明的目的，并且固定焦距装置300的结构简单、造价低、容易实现，且稳定性较好，能够解决样品随移动平台移动而造成的焦距偏离的问题。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同或相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将 是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
