线切割机具有加工材料和形状的适用范围广、精度高、加工成品无毛刺、耗材不易损坏且成本较低等优点，是目前应用较广的切割设备。随着线切割技术的发展，对线切割设备的加工质量和加工效率要求越来越高。
线切割设备进行加工时，特别是对硬脆材料进行截断、开方、切片等加工时，切割液的清洁度对工件成品的质量有很大影响。因此，为了提高切割液的清洁度，切割液的循环系统中会设置用于过滤切割液的过滤装置。过滤装置能够有效过滤切割液中的线头、颗粒等杂质。但是线切割加工中，尤其是切片时，会产生大量细微粉尘，造成过滤装置在使用中过滤网逐渐被堵塞，导致过滤效果变差，切割液流量降低，引起加工过程中跳线、断线等问题，进而影响工件的质量和加工效率。目前采用人工手动清洗或更换过滤网，在拆卸过滤网时过滤循环系统需暂停运行，导致切割液的供应暂停，影响线切割设备的加工效率。且人工清洗的效果不定，可靠性较低。
基于以上考虑，本申请提供了一种用于切割液的过滤装置，能够实现对过滤装置中过滤网的自动清洗，清洗效果较好，可靠性较高，且清洗时无需拆卸过滤网，清洗效率较高，有利于提高线切割设备的加工效率。

通过设置供液装置10和喷淋装置20能够实现切割液的喷淋，通过设置收集装置80能够实现切割液的回收再利用，有利于环保，通过设置过滤装置50能够对使用过的切割液进行过滤，以提高切割液的清洁度，进而减小回收的切割液内的杂质对工件加工的影响，能够提高工件成品的质量。

具体的，过滤循环系统循环步骤如下：
在切割作业，比如切片加工前，切割液存储于供液装置10中；
切片作业中，切割液经切割液入口57由供液装置10进入过滤筒内，此时过滤筒的状态为反冲气管路断开，切割液出口51打开，排污管路92断开，清洗液进液管路126断开；经过滤网56过滤后由切割液出口51流出，进入换热装置30，换热装置30采用工厂冷却水对切割液进行冷却，冷却后的切割液经过流量计40通过喷淋装置20的喷淋管均匀喷淋在工件切割区域，并经切割室底部回流至供液装置10中，形成加工过程中的切割液循环；
切割一刀后回流切割液时，切割液出口51(切割液出口夹管阀511)关闭，排污口52(排污口夹管阀510关闭)打开，换热装置30内的切割液回到过滤筒，再和过滤筒内留存的切割液一起，从过滤筒的排污口52或者切割液出口51通过回流管回到供液缸，即排污管路92和切割液输出管路91都可以和回流管连通，由供液装置10的排水口排放至地沟中。切片作业完成后，切割液输出管路91断开，排污管路92导通，将过滤筒中留存的切割液回流至供液装置10中，由供液缸的排水口排放至地沟中。
在切片完成后，打开清洗液进液管路126，保证清洗时过滤筒内充满清洗液，打开超声波清洗组件120，超声波清洗组件120将电能转换成超声能量，并按其自身规律传递给水垢、水、管道内壁，使之获取很大的能量。超声波在传递过程中产生的震荡波使水垢、水、过滤网56产生共振，由于水垢、水、过滤网56的震荡频率不同，过滤筒中的水分子发生激烈碰撞，生强大的冲击力，冲击过滤网56上的垢层，使之松脆、剥离、脱落、粉碎，并随排污一起排出，从而实现了超声波清洗组件120对过滤网56的彻底清洗，清洗完成后排污管路92打开，清洗后污水回流至供液装置10中经地沟排出。

过滤筒1的切割液入口18与供液缸出水口连接，切割液出口82与切割液系统中换热器的入口连接，在进行供液循环时，切割液由供液缸经过供液泵由切割液入口18进入滤网内部空间，切割液在经过不锈钢滤网过滤后，进入筒内滤网外部空间，并经过切割液出口82流入换热器，而切割液中的线头、硅渣等杂质被滤网拦截在滤网内部空间，同时，在切割液输出管路8上设置有切割液输出控制阀81，可以控制该路的通断。过滤筒1的排污口62与供液缸或者地沟连接，被拦截在滤网内部空间的杂质在切割作业完成后，可经排污口62排放至供液缸或者地沟中，在排污管路上设置有切割液排污控制阀61，可控制该路的通断。同时，在排污管路上切割液排污控制阀61与过滤筒1之间通过三通连接有清洗液进液管路7，该清洗液进液管路7连接工厂用水，可通过清洗液控制阀控制往过滤筒1中注入超声清洁用水。

请参照图19，图19为本申请一些实施例提供的用于切割液的过滤装置的清洗方法的流程示意图。过滤装置包括过滤筒1、过滤网2以及超声波清洗组件3，过滤网2设置于过滤筒1内，超声波清洗组件3的至少部分设置于过滤网2内，用于对过滤网2进行超声波清洗；
清洗方法包括：
S11、判断线切割机是否处于切割作业状态。
S12、若线切割机处于切割作业状态，则超声波清洗组件3对过滤网2进行清洗。
在一些实施例中，切割作业状态的判断可通过开机信号、或者线切割机的电机转数或其他信号进行判断，同时，一般认为切割作业状态时，切割液已开始循环，即可以将过滤筒1是否有切割液输入作为判断线切割机是否处于切割作业状态的信号，即，当过滤筒1的切割液输入管路 检测到有切割液通过时，认为线切割机当前处于切割作业状态。在对过滤网2清洗后，还可以控制将清洗后的切割液排出过滤筒1，继续进行切割液系统循环，即实现在切割液循环过程中不停机对过滤网2进行清洗，提高整个切割液循环作业过程中过滤网2的过滤精度，降低断线率。
在一些实施例中，超声波清洗组件3对过滤网2进行清洗的方式可以为超声波清洗组件3以预设清洗周期对过滤网2进行清洗，预设清洗周期包括第一作业时长和第一间隔时长，其中，第一作业时长可以为5秒，第一间隔时长可以为10秒。在线切割机的完整作业周期中，持续以上述预设清洗周期进行清洗作业。
其中，预设清洗周期可通过设置不同的第一作业时长和第一间隔时长实现，具体可参照上文所述进行设置；在另一实施例中，根据切割作业时长的不同，预设清洗周期随时间改变，如切割作业时长为三十分钟，在第一个十分钟内，第一作业时长和第一间隔时长可分别设为5秒；在第二个十分钟内，第一作业时长可设置为8秒，第一间隔时长可设置为5秒；在第三个十分钟内，第一作业时长可设置为10秒，第一间隔时长可设置为3秒；可根据需要进行第一作业时长和第一间隔时长的设置，均在本申请的保护范围内。
在另一些实施例中，超声波清洗组件3对过滤网2进行清洗的方式可以为超声波清洗组件持续对所述过滤网进行清洗。
本申请中，当线切割机处于切割作业状态时，控制超声波清洗组件3以第一预设方式对过滤网2进行清洗，以将附着在过滤网2上的硅粉进行清扫，防止硅粉附着在过滤网2上堵塞网孔，有利于带有硅粉的切割液能够顺利通过过滤网2，采用上述清洗控制方法的过滤装置能够在满足切割液流量的使用需求前提下适用更大目数的过滤网2，有利于提高切割液过滤杂质的精度，减少切片过程中跳线或断线问题，并有利于提高切割质量。
在一些实施例中，超声波清洗组件对过滤网进行清洗之前还包括：
S13、判断过滤筒的内部压力值是否大于第一预设压力值；
若过滤筒的内部压力值大于第一预设压力值，则执行超声波清洗组件对过滤网进行清洗的步骤。
通过检测过滤筒1的内部压力值，间接推断过滤网2的网孔堵塞程度，当内部压力值大于第一预设压力值时，认为过滤网2的网孔需要清理，其中，第一预设压力值可设置为0.1～0.5Mpa，可根据线切割机工作需要进行设置；内部压力值可通过在过滤筒1上设置压力检测组件4进行检测，压力检测组件4可设置为压力传感器，其具体的安装方式可参考现有技术设置。
在一些实施例中，超声波清洗组件对过滤网进行清洗之前还包括：
S14、判断过滤筒的内部压力值是否小于第二预设压力值，第二预设压力值小于或等于第一预设压力值；
S15、若过滤筒的内部压力值小于第二预设压力值，则超声波清洗组件停止对过滤网进行清洗。
当过滤筒1的内部压力值小于第二预设压力值时，认为当前过滤网2的网孔堵塞情况良好，可暂时停止对过滤网2进行清洗；第二预设压力值可设置在0.08～0.1Mpa，如0.08Mpa或0.1Mpa；由此以在保证过滤网2的过滤精度的同时，节约能源，控制切割成本。
在一些实施例中，超声波清洗组件对过滤网进行清洗之前还包括：
S16、判断过滤筒的切割液输出流量值是否小于预设流量值；
若过滤筒的切割液输出流量值小于预设流量值，则执行超声波清洗组件对过滤网进行清洗的步骤。
在一些实施例中，可通过在过滤筒1的切割液输出管路8上设置流量检测组件，对过滤筒1的切割液输出流量值进行检测，流量检测组件可设置为流量计；在切割液输出流量值小于第一预设流量值时，控制超声波清洗组件3对过滤网2进行清洗。在一种实施例中，可同步进行过滤筒1的内部压力值和过滤筒1的切割液输出流量值的判断，即，当线切割机处于切割作业状态时，且过滤筒1的内部压力值大于第一预设压力值、以及过滤筒1的切割液输出流量值小于第一预设流量值时，控制超声波清洗组件3对过滤网2进行清洗，由此以更进一步对过滤网2的堵塞情况进行精准判断，防止发生误报，减少耗能，同时延长超声波清洗组件3的使用寿命。
在一些实施例中，判断为线切割机处于切割作业状态之后，还包括：
S17、判断线切割机的切割作业时长是否大于或等于第一预设时长；
若线切割机的切割作业时长大于或等于第一预设时长，则执行超声波清洗组件对过滤 网进行清洗的步骤。
即，当线切割机处于切割作业状态至少第一预设时长后，进行超声波清洗组件3对过滤网2的清洗，由此以能够在线切割机开机并稳定运行后进行过滤网2的清洗，防止刚开机时运行功率过大造成系统过载，或发生其他作业事故；提高系统安全性。
同时，在另一实施例中，也可以在步骤S11之后进行切割次数的判断，以作为超声波清洗组件3对过滤网2进行清洗的前置条件。
在一些实施例中，超声波清洗组件对过滤网进行清洗之前还包括：
S18、判断线切割机的切割次数是否大于或等于预设切割次数；
若线切割机的切割次数大于或等于预设切割次数，则执行超声波清洗组件对过滤网进行清洗的步骤。
上述方法的设置，均是为了在线切割机处于切割作业状态并稳定运行后，进行过滤网2的清洗，同时也避免在未切割时就多次对过滤网2进行过多清洗，降低系统耗能，同时延长超声波清洗组件3的使用寿命。
在上述各实施例的基础上，第一预设方式为控制超声波清洗组件3持续对过滤网2进行清洗，由此以能够进一步提高过滤网2在整个作业过程中对杂质的过滤精度，提高过滤效果；或者，在另一实施例中，第一预设方式具体为控制超声波清洗组件3以预设清洗周期对过滤网2进行清洗。其中，预设清洗周期可通过设置不同的第一作业时长和第一间隔时长实现，具体可参照上文所述进行设置；在另一实施例中，根据切割作业时长的不同，预设清洗周期随时间改变，如切割作业时长为三十分钟，在第一个十分钟内，第一作业时长和第一间隔时长可分别设为5秒；在第二个十分钟内，第一作业时长可设置为8秒，第一间隔时长可设置为5秒；在第三个十分钟内，第一作业时长可设置为10秒，第一间隔时长可设置为3秒；可根据需要进行第一作业时长和第一间隔时长的设置，均在本申请的保护范围内。
在一些实施例中，清洗方法还包括：

S130、判断所述超声波清洗组件的作业时长是否大于或等于第二预设时长；
S140、若超声波清洗组件的作业时长大于或等于第二预设时长，则超声波清洗组件停止清洗。

当线切割机处于非切割作业状态时，控制切割液排污管路6和切割液输出管路8断开，即为控制排污阀和切割液出水阀断开；使得清洗水不会流入至切割液输出管路8中，进而减少清洗水的混入以及从喷淋装置喷淋出去的可能性，保证切割液的洁净度；控制清洗液进液管路7导通(清洗控制阀导通)，直至清洗液充满切割液循环系统的过滤筒1，再将清洗液进液管路7关闭，保证清洗时过滤筒1内充满水；控制超声波作业，工作频率范围为15KHz≤f≤80KHz，以预设频率对对过滤网2进行清洗。

其中，非切割作业状态为线切割机在切割作业外的其他状态，均为非切割作业状态，如包括在线切割机开机后但未进行切割作业的状态，以及线切割机的切割装置处于暂停作业、物料进行上下料的上下料状态，均包括在本申请非切割作业状态中。优选地，非切割作业状态为上下料状态，此时线切割机的切割装置处于暂停作业、而物料进给装置进行上下料作业，由此设置，在两次切割作业间隙过程中，对过滤网56进行清洗，保证切割作业效率和滤网清洗效果。同时，使得整个工序更为紧凑。
S21还包括：若线切割机未处于非切割作业状态，则重复进行步骤一的判断。即只有判断线切割机处于非切割作业状态时，才进行清洗操作，否则，对线切割机的作业状态进行再一次的判断。
