附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图3是本发明实施例一中摄像头拍摄的滚轮上墨滴的检测图像示意图。
图4是本发明实施例二一种喷墨涂胶设备的吐墨收集控制方法的流程示意图。
具体实施方式
以下各实施例的说明是参考附图，用以示例本发明可以用以实施的特定实施例。
请同时参照图1和图2所示，本发明实施例一提供一种喷墨涂胶设备的吐墨收集装置，包括：
溶剂槽17和可转动地安装在所述溶剂槽17上的滚轮11，所述滚轮11用于收集墨滴12，所述溶剂槽17盛放有用于与所述墨滴12相溶解的溶剂14，所述滚轮11绕轴线转动使收集的所述墨滴12与所述溶剂槽17中的所述溶剂14相接触；
吸附单元15，用于沿所述滚轮11轴线移动并吸附所述滚轮11上残留的溶剂14。
具体地，溶剂槽17为顶部具有开口的长方体结构，其内储存有溶剂14来对滚轮1进行清洗。溶剂槽17还设有用于装入溶剂14的进液管18和用于排出溶剂14的排液管19。溶剂14通过安装在溶剂槽17顶部的进液管18被装入溶剂槽17，需要更换时，将溶剂1通过安装在溶剂槽17底部的排液 管19排出，实现溶剂14的更新。
滚轮11包括旋转轴110和包覆在旋转轴110上的面层111，旋转轴110两端分别安装在溶剂槽17的相对两侧，面层111用于收集墨滴12并绕旋转轴110旋转。墨滴12从喷墨头(printer head)2喷吐在滚轮11之后，滚轮11绕轴线转动，使其上的墨滴12与溶剂槽17中的溶剂14相接触，通过溶剂14溶解墨滴12，达到清洗滚轮11的目的。滚轮11可以选用耐腐蚀性较好，发光性较好的钢材质制成。
滚轮11上的墨滴12被溶剂槽17中的溶剂14溶解后，滚轮11上往往残留有溶剂14，为了使滚轮11能够重复使用，需要对其进行去溶剂处理。本实施例设置了吸附单元15来吸附滚轮11上残留的溶剂14。吸附单元15包括固定安装在溶剂槽17上的丝杆152、可移动地安装在丝杆152上的移动块150，移动块150上安装有用于吸附滚轮11上残留溶剂14的吸附头151。移动块150内还设有电机，带动移动块150沿滚轮11的轴向移动。吸附头151朝向滚轮11并与滚轮11的圆弧形侧面相接触，并且相应于滚轮11的圆弧形侧面，吸附头151也具有圆弧形轮廓，至少覆盖滚轮11一部分面积。当移动块150在丝杆152上沿滚轮11轴向移动时，吸附头151可以对滚轮11侧面上残留的溶剂14进行吸附。吸附头151的吸附作用通过真空吸附实现，在吸附头151内设有真空管16，用于连接真空设备提供真空吸附力。
进一步地，本实施例吐墨收集装置还具有墨滴检测功能，具体地，本实施例吐墨收集装置包括摄像头13，用于拍摄获得滚轮11上的墨滴图像以供判断滚轮11上的墨滴12是否缺失。请参照图3所示，为摄像头13拍摄得到的滚轮11上的墨滴12的图像。根据该图像可以判断墨滴12是否有缺失。由于墨滴12是从喷墨头2吐出在滚轮11上，如果喷墨头2发生堵塞，将导致墨滴12吐出不连续，在前述图像上即体现为墨滴12不连续，出现缺失。因此，如果根据该图像判断墨滴12存在缺失，则表明喷墨头2发生堵塞。由此实现本实施例吐墨收集装置的墨滴收集与墨滴检测的一体化，减少装置的总体积。
需要说明的是，根据滚轮11的旋转方向，相应元件的设置位置有所不同。由于滚轮11收集到喷墨头2吐出的墨滴12后，如果需要判断墨滴12 是否缺失，则需在滚轮11转动至溶剂槽17之前，由此，按滚轮11的旋转方向，摄像头3设置在溶剂槽17之前。同样地，吸附单元15是用来吸附滚轮11经溶剂槽17清洗后仍残留的溶剂14，则该吸附需在滚轮11转动至溶剂槽17之后，由此，按滚轮11的旋转方向，吸附头151设置在溶剂槽17之后。上述位置关系也可以表述为，按滚轮11的旋转方向，溶剂槽17设置在摄像头3与吸附单元15之间。
本实施例吐墨收集装置的工作过程和原理是：墨滴12从喷墨头2喷吐在滚轮11上，滚轮11旋转90°(图1所示为顺时针旋转，根据元件布置也可以逆时针旋转)到达摄像头13的拍摄范围，摄像头13生成墨滴12在滚轮11上的检测图像，以供判断墨滴12是否有缺失；然后滚轮11继续顺时针旋转90°，带有墨滴12的滚轮11到达溶剂槽17，墨滴12与溶剂槽17中的溶剂14相互溶解，对滚轮11上的墨滴12进行清洁；然后，滚轮11再顺时针旋转90°到达吸附头151的位置，通过移动块150的带动，吸附头151沿着滚轮11轴向移动，对滚轮11表面的残留的溶剂14进行真空吸附，达到滚轮11重复利用的目的。当然，需要进行吐墨操作时，喷墨头2也可以移动到滚轮11上方进行吐墨操作，然后通过滚轮11旋转，执行上述溶剂14对滚轮11的清洗、吸附头151对溶剂14进行去溶剂处理的流程，使滚轮11可以重复使用。
如图4所示，相应于本发明实施例一的吐墨收集装置，本发明实施例二还提供一种喷墨涂胶设备的吐墨收集装置的控制方法，吐墨收集装置包括溶剂槽、可转动地安装在所述溶剂槽上的滚轮以及沿所述滚轮轴线移动的吸附单元，该控制方法包括：
通过所述滚轮收集墨滴；
旋转所述滚轮至所述溶剂槽，使所述滚轮上的墨滴与所述溶剂槽中的溶剂相溶解；
继续旋转所述滚轮，使所述吸附单元与所述滚轮相接触并吸附所述滚轮上残留的溶剂。
其中，所述吐墨收集装置还包括摄像头，所述控制方法包括：在滚轮旋转至所述溶剂槽之前，通过所述摄像头对所述滚轮拍照，获得所述滚轮上的 墨滴图像。
通过上述说明可知，本发明实施例的有益效果在于：利用溶剂清洗、吸附头吸附溶剂的方式可以重复利用滚轮，相对于现有方式不需要选用film等耗材；同时通过摄像头对滚轮上的墨滴进行拍摄，可用于判断喷墨头是否堵塞，使墨滴收集与墨滴检测一体化，减少了装置的总体积。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
