现有的激光清洗通常采用一聚焦光斑，将待清洗物体与线型光斑对位后，即可实现待清洗物体的二位平面清洗，若需要对平面其他区域进行清洗，则需要移动待清洗物体或线型光斑，而线型光斑通常以一聚焦点形式呈现，从而在扫描移动的过程中，以“之”字形移动，由于光斑或待清洗物体的移动速度的影响，会导致线型光斑的切换之间的间距较大，从而导致其表面残留污染物，影响清洁效果。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种激光清洗光路，能够形成面型光斑，提高激光清洗聚焦后的激光覆盖面积，从而在切换区域的过程中，减少间距误差，避免污染物残留，具有提高其激光清洗效果的优点。
为实现上述目的，本发明提供了如下技术方案：

具体实施方式
参照图1至图4对激光清洗光路做进一步说明。
一种激光清洗光路，如图1所示，包括若刚相互拼接的壳体1以及设于壳体1内的激光清洗光束2，壳体1的横截面设置为方形，即成型为方形体，使其能够沿前后左右进行拼接，若干个壳体1向X轴或Y轴方向依次拼接，从而根据待清洗工件的清洗表面需求，依次拼接，覆盖清洗表面的宽度方向，即可直接通过移动多个壳体1沿清洗表面的长度方向移动，无需形成“之”字形移动，减少出现光斑切换情况，即无间距误差，避免污染物残留，具有提高其激光清洗效果的优点。
如图1和图2所示，在壳体1对称的外侧壁上分别设置有定位座13与定位槽14，壳体1为方形便具有四个表面，由此在两两对称的表面上对称设定定位座13与定位槽14，以便于在壳体1的任意一表面进行拼接使用，从而能够根据工件待清洗表面形状需求，配置对应形状的壳体1范围进行覆盖。其中，可以先对待清洗表面均匀分化区域，以确定分出单独区域的形状，之后拼接对应小区域范围形状的壳体1总成来使用，在一个分化的小区域清洗后，直接转移至下一小区域覆盖即可，减少位移间距差，并提高清洗效率与清洗效果。具体的，定位座13定位插接于定位槽14内，且在定位座13与定位槽14的槽壁之间通过磁吸结构磁吸定位设置，定位座13与定位槽14的横截面均设置为梯形，从而能在二者沿竖直方向插入后避免水平方向脱离。在定位座13靠近定位槽14的底面上设定金属磁性片，在定位槽14的槽底设定磁吸块，从而在定位座13插入定位槽14内后，即可利用磁吸块与金属磁性片的磁性力将二者定位配合，拆卸时，只需施力将二者分开即可，从而方便若干个壳体1的拼接使用，以提高操作使用的便捷性。
如图1和图3所示，其中，在壳体1的出光端处设置有用于调整激光清洗光束2的出光角度的调节件3，在各个壳体1拼接后，利用调节件3调整各个激光清洗光束2，使各个激光清洗光束2汇聚于同一平面上，且彼此相互紧邻设置，从而形成面型光斑，提高激光清洗光束2覆盖范围，使其沿清洗表面长度方向移动的过程中，减少位移间距差，提高清洗效果，且激光清洗光束2覆盖范围大，能够提高清洗效率，减少区域切换清洗频率，进一步缩短间距误差，提高清洗效果。
如图3所示，调节件3包括转动设于壳体1出光端处的反射镜31以及设于壳体1内的偏转电机32，偏转电机32的输出端与反射镜31连接，方便调整反射镜31的反射角度。具体的，反射镜31通过安装座33与偏转电机32连接，在偏转电机32带动安装座33移动时，即可带动反射镜31进行角度的切换，方便快速调整反射角度进行使用。
如图3所示，在安装座33远离反射镜31出光表面的一侧上设置有用于将激光形成线状光束的透镜片7，透镜片7对位于反射镜31的出光线路设置，透镜片7采用鲍威尔棱镜制成，以便于提供线状清洗激光进行使用，从而利用少量的壳体1拼接，即可成型覆盖范围较大的激光清洗光束2，方便使用，节省成本。对于不同的待清洗表面，线状激光所需要的长度大小不同，由此，在安装座33上位于线状光束的两端位置处设置有遮光板8，遮光板8滑动设于安装座33上，且遮光板8抵触于透镜片7的出光表面上，安装座33上设有用于驱动遮光板8沿线状光束延伸方向滑动的直线移动机构9，通过直线移动机构9调整遮光板8在透镜片7上的位置，即可利用遮光板8遮住线状激光两端，调整线状激光经过透镜后的成型的长度大小，满足不同的清洗工件需求。
如图3所示，壳体1内沿激光清洗光束2传输方向上依次设置准直镜4与聚焦镜5，使激光清洗光束2接入壳体1内后，先经过准直镜4形成平行光 束，再通过聚焦镜5聚焦使用，从而便于有效进行激光清洗作业。激光清洗光束2的成型，首先通过激光发生器摄入壳体1内，由壳体1内的准直镜4准直使其平行后，再通过聚焦镜5聚焦成型，之后的激光清洗光束2经过反射镜31反射至所需要的角度位置，再通过透镜折射形成线状激光，从而方便提供线状激光光束进行清洗作业。
如图3所示，对于部分杂质可能需要多次进行激光清洗，若在经过多次激光清洗后，则工件表面残留的杂质变薄，此时利用不聚焦的激光即可清洗完成，以保护工件的基体不受损坏。由此，在聚焦镜5的一侧通过转动轴铰接于壳体1的内侧壁上，转动轴的轴向与激光清洗光束2的传输方向相互垂直设置，且壳体1的内侧壁上设有用于容纳聚焦镜5的容纳槽11，转动轴连接有用于驱动其转动的转动件6，转动轴转动时带动聚焦镜5转入容纳槽11或壳体1的出光端上，若需要聚焦，则将聚焦镜5转入壳体1的出光端上，若无需对焦，则将聚焦镜5转入容纳槽11中，利用准直后的激光通过反射镜31与透镜的配合，直接作用在工件上，从而能够避免对浇薄杂质的清洗时给工件基体带来损伤。其中，壳体1供聚焦镜5定位于其出光端的位置处设置有定位沿12，能够便于聚焦镜5移动到位后的定位反馈，提高使用的便捷性。
如图3所示，为了便于自动化控制，转动件6设置为旋转气缸，旋转气缸的输出轴与转动轴连接，且旋转气缸连接并受控于控制器上，以便于自动化控制聚焦镜5的位置变化，方便操作使用。进一步的，偏转电机32以及直线移动移动机构均连接并受控于控制器上，以便于自动化控制反射镜31的角度调整以及线状激光的长度调整，提高操作使用的便捷性。
如图3和图4所示，具体的，直线移动机构9包括连接于两个遮光板8的丝杆91以及与丝杆91连接的丝杆电机92，丝杆91自其中点向两端的方向分别设置有两段螺纹方向相反的螺纹线，遮光板8与螺纹线螺纹连接，以便于通过一个丝杆91的转动，同步带动两个遮光板8向相互靠近或相互远离的 方向移动，从而方便调整线状激光光束的长度大小，提高调整速率以及便捷性。进一步的，遮光板8包括遮光体81以及设于遮光体81两侧的滑动块82，滑动块82位于透镜片7两侧，且安装座33上开设有供滑动块82滑动的移动槽，丝杆91螺纹穿设过两个遮光板8的滑动块82设置，从而能够避免丝杆91影响透镜的折射，同时又便于丝杆91带动遮光板8移动，提高线状激光长度调整的便捷性，以满足多种产品的激光清洗需求，提高清洗效果。
工作原理：在使用时，对于小型的待清洗工件的清洗，可将若干个壳体1沿同一直线进行拼接，并利用调节件3调整拼接后的线状激光光束，并通过直线移动机构9调整单个线状激光的长度大小，使各个激光清洗光束2首尾衔接并处于同一直线上，使其拼接后的激光清洗光束2不小于待清洗工件的宽度大小；接着以待清洗表面长度大小，依次拼接多条激光清洗光束2，并使其相互紧邻，提高激光清洗光束2的覆盖范围，之后将拼接后的壳体1沿待清洗工件表面的长度方向移动，即可全面对待清洗工件表面进行激光清洗，由此在清洗过程中，无需以“之”字切换区域，且切换区域的过程中，减少间距误差，避免污染物残留，具有提高其激光清洗效果的优点。若对于大型的待清洗工件进行清洗，可先对待清洗工件的待清洗表面进行均匀的区域划分为若干个小区域，接着拼接若干个壳体1，并调整激光清洗线束的长度大小以及位置，使其拼接后成型的形状以及面积与小区域形状以及面积大小一致，即可进行清洗，清洗时以一个小区域为单位依次进行清洗，从而依次全面进行激光清洗作业，由此，能够形成面型光斑进行清洗，提高激光清洗聚焦后的激光覆盖面积，且清洗分区域依次进行，对于单个区域能够全面覆盖，从而在切换区域的过程中，减少间距误差，避免污染物残留，具有提高其激光清洗效果的优点。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应 当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
