Description

一种用于数控激光切割***的工件平整度预采集装置 技术领域
本发明属于数控激光切割***自动调高控制技术领域，尤其适应激光切割机床加工对高度要求较粗糙的材料，比如：亚克力。
背景技术
激光切割机利用高功率密度激光束照射被切割材料，使材料很快被加热至汽化温度，蒸发形成孔洞，随着光束对材料的移动，孔洞连续形成宽度很窄的(如0.1mm左右)切缝，完成对材料的切割。
由于激光光斑小、能量密度高、切割速度快，因此激光切割能够获得较好的切割质量。激光切割成形技术在非金属材料领域有着较为广泛的应用。不仅可以切割硬度高、脆性大的材料，如氮化硅、陶瓷、石英等；还能切割加工柔性材料，如布料、纸张、塑料板、橡胶等，如用激光进行服装剪裁，可节约衣料10％～12％，提高功效3倍以上。
激光切割机均采用数控加工***，可实现极精细的加工轨迹和激光功率实时调节。激光切割机床必须保证激光束聚焦焦点正好落在被切割工件上，但是由于工件表面存在凹凸不平，这将导致激光加工出现加工不良的问题，切缝过宽、切割不彻底、工件粘连等实际加工问题，影响成品率。解决此类问题，***需增加自动调高器。目前市场激光切割自动调高器大多采用电容检测式，此方法有效解决金属切割过程中高度自动调节问题。但由于依赖电容参数作为反馈值，所以不能用于非金属材料的切割。
发明内容
针对上述所述激光切割调高***所存在的问题与不足之处，本发明提供一种加工工件表面高度预采集装置，事先采集工件信息，形成工件高度图，在接下来的切割过程中采用采集好的信息对加工高度进行Z轴补偿，实现数控***精确的切割高度控制。此装置采用接触式电阻式位移传感器采集高度信息，可以用在加工材料为非金属材料，比如：亚克力板、木板。
本发明所述的工件平整度预采集***包括三部分内容：硬件组成、高度信息采集方法、切割过程补偿方法。
(1)***硬件组成
工件平整度预采集***硬件由两大部分组成，一部分为Z轴调高***，一部分为运动控制卡。两者通过通信相互配合。其中Z轴调高***为主要硬件设计部分，负责高度信息采集和Z轴电机驱动，为从属执行机构。运动控制卡负责向Z轴调高***发送高度采集指令和计算补偿值，并发送给Z轴调高***进行补偿，实现控制中心功能。运动控制卡采用本公司已有产品。
Z轴调高***由电机驱动部分、工件高度采集部分、信息传输部分组成。运动控制卡仅实现计算和通信，不做具体硬件说明。
Z轴调高***电机驱动部分采用步进电机和丝杆组成，驱动采用基于矢量控制的三相步进电机细分驱动设计。采用矢量控制电流环响应速度快；速度环可以设置启动速度、加速度、运行速度等，根据不同的负载要求设置对应的参数；位置环采用梯形图运动轨迹，整个阶段由加速过程、匀速过程、减速过程构成，运转平稳。
Z轴调高***工件高度采集部分采用电阻式位移传感器，位移行程50mm，可以适应大多数材料的切割高度变化，信号采集通过12位模数转换把模拟信号转换为数字信号，然后转换为高度信息。
Z轴调高***信息传输部分包含两部分：
1.从Z轴调高***到运动控制卡方向的传输，主要传输信号为装置采集到的高度信息，采用隔离电源供电的N-BUS总线实现采集到的高度信息传送到运动控制卡，N-BUS总线的最高传输速率可以达到1Mbit/s。
2.从运动控制卡到Z轴调高***方向的传输，主要传输信号为下发到Z轴驱动器装置的高度补偿信号，这里可以采用三种方式传输，第一，采用脉宽调制信号，不同高度的补偿信息转换为相应占空比的脉宽信号发送到Z轴驱动器装置；第二，采用模拟电压信号，不同高度的补偿信息转换为相应大小的模拟电压值信息，传送到Z轴驱动器装置；第三，采用N-BUS总线信号，不同高度信息值通过总线直接把数字信息发送到Z轴驱动器装置。这里采用脉宽调制信号进行实际传输信号。
(2)高度信息采集方法
采集高度信息的过程，根据不同规格尺寸不同平整度的加工材料，设置高度采集点个数，所有高度采集位置均匀的分布在加工材料平面上，欲得到较详细的工件高度信息可以适当增加采集点密度，采集点越多需要运动控制卡处理的高度补偿信息计算量越大，工件切割效果越好。
(3)切割过程补偿方法
***采集完所需的高度信息后，切割头回到加工原点，开始加工过程，加工过程中运动控制卡根据运行轨迹和高度信息对Z轴调高***通过脉宽调制信号实时发送高度补偿信息，Z轴进行高度补偿。
此装置工作整体过程描述：进行加工之前，首先进行高度信息采集，运动控制卡通过N-BUS总线发送高度采集指令给Z轴调高***，Z轴调高***通过传感器采集完高度信息，通过N-BUS总线反馈给运动控制卡，运动控制卡记录下数据，此过程持续采集完所有需要采集的位置高度；接下来，运动控制卡计算整个加工区域的高度补偿信息；加工的过程中，运动控制卡通过脉宽调制信号把相应位置的高度补偿信息下发给Z轴调高***，Z轴调高***进行高度补偿。

图4为本发明Z轴调高***里高度采集部分电路框图；
图5为本发明的采集方法说明示意图；
具体实施方式：
下面结合具体实施例和附图对本发明作进一步说明书，但不应以此限制本发明的保护范围。
1.***硬件组成
工件平整度预采集***硬件由两大部分组成，一部分为Z轴调高***，一部分为运动控制卡。两者通过通信相互配合，框图结构见图1。其中Z轴调高***为主要硬件设计部分，负责高度信息采集和Z轴电机驱动，为从属执行机构。运动控制卡负责向Z轴调高***发送高度采集指令和计算补偿值，并发送给Z轴调高***进行补偿，实现控制中心功能。
Z轴调高***由电机驱动部分、工件高度采集部分、信息传输部分组成，结构关系见图2。
Z轴调高***电机驱动部分采用TI数字信号处理器F2808作为控制核心，所有电机控制SVPWM等由此编写实现；三相电机逆变采用大电流MOSFET管75NF75搭建；电机电流闭环需采集电机相电流，采用双电阻法采集相电流；电机驱动部分还具有温度采集电路、过流保护电路、硬件刹车电路、电压监测电路；具体见图3。
Z轴调高***工件高度采集部分采用电阻式位移传感器，位移行程50mm。传感器信号处理电路采用差分运算放大器，有效减小共模噪声，放大器输出添加幅值保护电路，确保信号不超过模数转换器的允许范围。模数转换器可以实现微秒级的采集速度，F2808芯片12位的采集分辨率有效保证高度信号的准确可靠。具体见图4。
Z轴调高***信息传输部分由Z轴驱动器装置到运动控制卡的数据传输，采用自主发明的N-BUS总线实现。N-BUS总线采用隔离电源：5V直流电源，由主设备提供，用于主设备控制***与N-BUS总线的信号隔离。从设备的控制***与N-BUS总线是否信号隔离不做强制要求，如果信号隔离，需使用此路电源。
N-BUS总线具有3路输入信号和1路输出信号组成。输入、输出方向均以主设备方向确定。输入信号分别定义为急停信号、暂停信号和其它信号。输出信号功能定义为使能信号。
Z轴调高***信息传输部分由运动控制卡到Z轴驱动器装置的补偿高度数据传输，采用脉宽调制信号实现，这里规定信号周期，补偿高度0值对应50％的占空比脉宽，正向补偿值和负向补偿值分别对应50％----100％占空比和0％----50％占空比。
2.高度信息采集方法
首先在运动控制卡端设置加工材料的尺寸和欲采集的高度点个数，运动控制卡根据这些信息确定高度 点采集坐标。运动控制卡控制安装有位移传感器的切割头移动到第一个采集点，通过N-BUS总线发送采集高度的命令给Z轴调高***，Z轴调高***完成采集后把高度信息通过N-BUS总线传送回运动控制卡，控制卡记录下此坐标下高度值，继续移动到相邻另一个采集点，重复操作。直到所有采集点高度信息采集完成。
采集点分布说明：按照材料长度和宽度等距离划分，以方格形式采集。图5显示了具体的采集方法。
3.切割过程补偿方法
切割过程中，运动控制卡根据相邻4个采集点的高度信息计算在此区域内切割轨迹的高度补偿信息，切割头在沿轨迹进行切割过程中，运动控制卡实时通过脉宽信号发送补偿信息到Z轴调高***，Z轴立刻进行高度跟随补偿。整个切割过程高度都会自动根据预存的高度信息进行自动调整。
