Description

一种激光打标机、激光打标方法、打标设备及打标系统 技术领域
本申请涉及激光打标技术领域，特别是涉及一种激光打标机、激光打标方法、打标设备和打标系统。
背景技术
激光打标可以打出各种文字、符号和图案等。激光打标是利用高能量密度的激光对工件进行局部照射，使表层材料汽化或发生颜色变化的化学反应，从而留下永久性标记的一种打标方法。
现有的打标机中，打标软件会根据操作者的解析度设置，保留设定的像素点，并根据红绿蓝三个子像素进行灰度计算，得到每个像素点的灰度值，通过单位面积内打标点的数目可以呈现图像的灰度差异，即依靠打标点的密度来实现灰度的呈现。但是由于单位面积小，肉眼根本无法看出他的存在，只能感觉到画面的连续变化性。现有的打标技术采用的是打标控制和激光控制相分离的方式，在激光的控制上采用的是粗狂式的线段控制，不能精确到打标点的控制上，使得打标的解析度不高，打标效率低。
与此同时，不同的材料吸收激光的程度是不一样。因此，对不同的材料进行加工时需要人工选择不同的激光器，例如手机外壳打标过程中，当外壳为塑胶或者碳纤维时，需采用5w以内的功率，功率过大则会直接损毁外壳；而对于金属外壳时，宜采用20w以上功率，功率过小则无法标刻成功，用户在需要对不同材料进行加工时，往往需要购买多种输出功率的激光器，这严重增加了用户的支出负担。
因此，目前需要本领域技术人员迫切解决的一个技术问题就是：如何使激光打标机的输出功率与需要打标的材料匹配的问题。
发明内容

所述控制主板采用所述灰度值计算目标图像像素点的输出功率；

一种激光打标系统，所述激光打标系统包括：控制平台、以及与控制平台信号连接的终端和激光打标机，所述激光打标机包括激光器和振镜，所述振镜用于采用预设的移动速度基于目标图像像素点的坐标进行位移；所述激光器用于输出激光；所述终端用于将待打标图像上传至所述控制平台，所述激光打标系统还包括：

位于所述控制平台的第一计算模块，用于根据所述灰度值计算目标图像像素点的输出功率；
位于所述控制平台的第二获取模块，用于获取待打标的材料信息；
位于所述控制平台的第三获取模块，用于根据所述材料信息获取对应的材料输出功率；

位于所述控制平台的控制模块，用于所述振镜的位移控制所述激光器采用相应的修正后输出功率，针对各目标图像像素点输出激光。
与现有技术相比，本申请实施例包括以下优点：
本申请通过调整目标图像像素点(打标点)的输出功率，使得独立的一个像素点即能体现灰度值的变换，以实现图像灰度值的呈现。

放弃通过打标点的密度来呈现灰度的方法，每一个打标点都可以体现灰度值，相对提高了打标效率。

具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请作进一步详细的说明。
参照图1为一般的打标机的结构框图，一般的打标机包括：CPU/打标软件、控制主板、光路、振镜部分。其中，CPU/打标软件主要负责图形(位图，矢量图，文字，二维码等等)的处理和编辑，会根据操作者的设置和打标条件，将图形转换为控制主板可以识别的打标指令，打标指令就是打标机打标时的动作拆分，每一个指令就是打标机的一个动作。产生指令之后，就将指令封装成约定协议的通信包，发送给控制主板。控制主板接收CPU发送的打标指令，将指令进行存储和解析，根据解析的数据控制后端的光路和振镜进行工作。激光通过振镜在平面上进行相对匀速的移动，这样就可以对被打标物件进行打标。
参照图2所示，为现有的激光打标机中灰度的表示方法。图中，单位面积全部实现雕刻覆盖，则灰度值最大，如果单位面积没有进行雕刻，则灰度值最小。通过对所有单位面积内的打标点进行拟合，生成指令，控制 主板可以根据指令的解析，控制激光和振镜的配合来完成这些区域面积的雕刻。
现有的方法尽管可以实现灰度差异的体现，但是存在以下几个缺点：
1、现有方法对图像基本像素点概念进行了转移，本来是点的概念，但是为了在雕刻中体现灰度，只能将点转移到单位面积上。这种概念的转移是以牺牲解析度和最小分辨率为代价的，最终的结果就是打标解析度不高，打标图像不够细腻。
2、为了突出灰度概念，大量的雕刻点团结在一起来体现一个像素点的灰度，由于图像最小单位的扩大，导致的结果就是打标的效率低。
3、打标机在打标过程中的速度和频率一般都是一定的，因此当像素的灰度发生变化的时候，必然导致点与点之间的距离发生变化，而这种变化只能依靠打标的空跳来实现。
本申请实施例的核心构思之一在于，单独控制每个目标图像像素点(打标点)的输出功率，将目标图像不同灰度的像素点转换为不同功率的打标点。
参照图3，示出了本申请第一实施例的一种激光打标方法实施例的步骤流程图，其中，使用激光打标机进行打标，所述激光打标机包括：控制主板、分别与控制主板相连的激光器和振镜；所述振镜用于采用预设的移动速度基于目标图像像素点的坐标进行位移；所述激光器用于输出激光；具体可以包括如下步骤：
步骤301，所述控制主板接收目标图像像素点的坐标，以及，目标图像像素点的灰度值；
步骤302，所述控制主板采用所述灰度值计算目标图像像素点的输出功率；
步骤303，所述控制主板随所述振镜的位移控制所述激光器采用相应的输出功率，针对各目标图像像素点输出激光。
在所述步骤301之前，所述方法还可以包括：
所述控制主板接收待打标图像，并将所述待打标图像转换为预设解析度的灰度图；
所述控制主板采用所述解析度计算出灰度图中各像素点的坐标，将所 述灰度图各像素点的坐标作为目标图像像素点的坐标。
基于现有激光打标方法中存在的问题，本申请提出了一种全新的灰度呈现方式，通过打标功率控制打标深度，使用打标深度控制打标灰度，换句话说就是功率越大，灰度越大，打标的过程就是将图像不同灰度的像素点转换成不同功率的打标点，参照图4示出了本申请实施例中的灰度表示方法。
在本申请实施例中，首先需要将待打标图像转换为灰度图，具体可以用户需要的解析度进行设置，解析度即构成灰度图的点的个数，例如，解析度为1024x768，即代表灰度图在横坐标上有1024个点，纵坐标上有768个点。根据预设的解析度对转换待打标图像，就能得到预设点数的灰度图。每个点的灰度值转换可由原图像中像素点的亮度值计算，亮度值即图像中红绿蓝3个子像素的数值。例如，灰度的转换公式可以为：gray＝0.3*red+0.59*green+0.11*blue。将灰度值转换成0-100的功率值，最后位图的3种子像素就转变成像素点坐标和每个点的功率值。
激光功率的大小取决于激光器中泵浦电流的大小，因此控制每个打标点的功率在一定意义上来讲，就是控制泵浦电流的大小。参照图5所示，是本申请中泵浦电流与激光功率的线性关系示意图。在一定范围内，泵浦电流的变化和激光功率的变化会有一个线性关系，里面会有一个系数K，也就是W＝IK，可以通过实验，找出这个线性范围，并且可以确定系数K。同理，在其他一些范围内，泵浦电流的变化和激光功率的变化呈现曲线关系。
打标软件根据解析度的设置和原图像中各像素点的亮度值，将位图转换为若干个不同灰度的像素点，一旦解析度确定之后，点与点之间的距离就确定了，一旦打标亮度确定之后，每个点的绝对灰度就确定了。这样，每个雕刻点的功率值和绝对坐标就确定了。
需要声明的是，在本申请中激光频率是指激光器每秒内输出的激光数目。在本申请中的打标方案中主要由3个要素组成，分别是：振镜速度，每个点的绝对坐标，每个点的打标功率。打标机会以设定的速度控制振镜匀速运动，当振镜到达某个点的绝对坐标之后，就会以这个点相应的功率进行打标。
参照图6是本申请实施例中激光功率控制示意图。图中示出了，脉冲、泵浦电流、光纤储能、振镜速度、振镜位移等几个参数的关系。在本申请实施例中，还定义了一个术语称为“激光周期”，激光周期是本申请中连接激光器与振镜的时序主线。
对激光器而言，激光周期即“泵浦电流更新-工作光纤储能-释放激光”的时间段。所述激光器包括：泵浦和与泵浦连接的工作光纤、以及与工作光纤连接的输出开关，所述输出开关可以为声控开关。在一个激光周期内，工作光纤接收泵浦输出的电流，开始光纤储能。在到达一个激光周期时，控制主板向声控开关发出打开指令，声控开关接收到指令打开开关，输出存储在工作光纤中的激光。
对振镜而言，激光周期即“振镜运动到打标点的坐标，并进行打标的”的时间段。为了实现激光器与振镜的在激光周期上相互匹配，对于振镜而言，需要注意以下3点：
1、振镜的运动包括三个阶段：加速区、匀速区、减速区。在实际中，激光器需要振镜处于匀速区的时候才能进行打标，因而，需要在振镜处于加速区或减速区时进行规避，避免激光器在这两个区进行打标。
2、振镜在进入匀速区后，会根据打标指令不断的运动，直至所有的点都完成打标。即在打标过程中，对于中途的打标点，振镜是不会在到达打标点后停止的。
3、现在振镜使用的协议基本上是XY2-100协议，参照图7为XY2-100协议的示意图。根据XY2-100协议，控制主板每隔10μs向振镜发送控制指令，控制指令包括下一个目标图像像素点的坐标，振镜中包括有(DA)模数转换器，振镜的DA将下一个目标图像像素点的坐标转换为振镜的移动参数，振镜根据移动参数移动到下一个目标图像像素点。但是这种协议本身就是一种不交互协议，因此控制主板只清楚位置命令是否传达完毕，而无法得知振镜是否执行完毕。
在本申请实施例中，所述步骤303包括以下子步骤：
子步骤S31，所述控制主板判断所述振镜位移至当前像素点的时间，是否到达预设的时间延迟；
子步骤S32，若是，则判定振镜位移至当前像素点；
子步骤S33，当判定位移至当前像素点时，所述控制主板控制激光器针对当前像素点输出对应输出功率的激光。
更进一步而言，所述预设的时间延迟包括：加速延迟、匀速延迟、减速延迟；
所述控制主板判断所述振镜位移至当前像素点的时间，是否到达预设的时间延迟包括三种处理情况；
第一情况是，在当前像素点为起始像素点时，所述控制主板判断所述振镜位移至当前像素点的时间，是否到达预设的加速延迟；所述起始像素点是激光打标机工作时的第一个打标点；
第二情况是，在当前像素点为中途像素点时，所述控制主板判断所述振镜位移至当前像素点的时间，是否到达预设的匀速延迟；所述中途像素点是激光打标机从第一个打标点打标至最后一个打标点的过程中的打标点；
第三情况是，在当前像素点为结束像素点时，所述控制主板判断所述振镜位移至当前像素点的时间，是否到达预设的减速延迟；所述结束像素点是激光打标机工作时的最后一个打标点。
鉴于上述3点注意事项，参照图8示出了本申请实施中激光实际控制的时序图。激光器的激光周期和声控脉冲需要寻找一个参照时间点来确认振镜是否到达坐标，在本申请实施例中选取XY2-100协议发送命令的最后一个时钟周期作为参照点，当命令发送完毕之后，等待相应的延时，采用等待延时来确定振镜移动的位置。等待延时即等待振镜的DA动作，等待电机运动到指令要求的下一个目标图像像素点坐标上去。由于采用XY2-100协议的控制主板是不会知道振镜当前位置的，又振镜在打标过程中可以视为保持匀速运动的状态，因此通过等待相应的延时，即可认为振镜到达下一个目标图像像素点。其中，延时分为“start_dly(起始延时)，mid_dly(中途延时)，end_dly(结束延时)”三种延时。
具体而言，在第0秒时，控制主板向振镜发送第一个指令，即控制振镜移动至第一个目标图像像素点(起始像素点)，这时，由于振镜的电机还没开始工作，即振镜的移动速度为0。振镜的电机从0加速至匀速需要一段时间，这段时间可以由实验测出。为了保证激光器是在振镜匀速运动 的过程中开始打标的，起始延时设定为大于电机加速时间即可。即等待起始延时后，振镜已经除在匀速区，并且已经到了起始像素点。在振镜之后的运动过程中，振镜一直保持匀速运动，这时延时为中途延时，即等待中途延时后，振镜移动到下一个目标图像像素点(中途像素点)。当振镜接收到的下一个像素点为目标图像的最后一个像素点(结束像素点)时，振镜会进行减速，从匀速减速为0。此时，延时为结束延时，即等待结束延时后，振镜移动到结束像素点。这三个延时可以根据实验得出。这样就可以保证振镜在打标过程中是连续匀速运动，又可以准确的确定打标点的坐标。
在本申请实施例中，所述激光器包括：泵浦和与泵浦连接的工作光纤、以及与工作光纤连接的输出开关；所述子步骤S33进一步包括：
子步骤S41，所述控制主板采用所述输出功率调整所述泵浦的输出电流；
子步骤S42，所述工作光纤接收所述输出电流进行光纤储能；
子步骤S43，当所述振镜移动至当前像素点时，所述控制主板发出开关指令，所述输出开关依据指令释放一个激光周期内的储能；所述激光周期为工作光纤开始储存能量至释放能量的时间。
在上述方案中，激光周期的最小值是由激光器本身的特性限制的，就是光纤储能速度等，也就是从二级电流为0时到电流变化到最大值这个时间段所限制。
一个打标点需要耗费一个激光周期，但是在实现的时候需要注意以下几个问题：
(1)控制二级电流变化的DA(数模转换模块)响应速度要比较快，转换速度比较快，目前100M-200M的DA应用比较普遍。
(2)当打标点的功率变换比较频繁的时候，就必须考虑光纤储能时间的问题，当比较小的功率向比较大的功率转变的时候，在一个激光周期内，就可能导致光纤储能时间不足，直接影响激光的功率不能满足要求。
通过调整振镜的移动速度来改变激光周期的大小，由于解析度确定好，灰度图中各点之间的距离就已经确定了，因而通过点间距离和振镜移动速度即可计算得到激光周期。
因此，在本申请实施例中，所述方法还包括：
所述控制主板采用所述输出功率调整所述振镜的移动速度。
由于光纤储能速度有限，为了保证一个激光周期内工作光纤储能能够满足所需要的功率，即需要调整激光周期的大小。又由于激光周期取决于点间距离，和振镜移动速度，在点间距离确定的情况下，就需要通过改变振镜的移动速度来使得激光周期内工作光纤储能够满足需要的功率。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本申请实施例所必须的。

同样，打标机可以与终端相连，终端通过有线或无线网络向打标机发送需要打标的图像，便于用户操作。终端如手机、PC或平板，打标图像不限于LOGO、照片、设计图以及3维图。
对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比 较简单，相关之处参见方法实施例的部分说明即可。
本申请第三实施例提出一种打标方法和打标系统，其核心构思之一在于，通过在智能处理中心设置材料信息与对应功率的匹配关系表，当打标平台在处理不同的打标材料时，都能选择到与打标材料匹配的激光输出功率范围。将待打标图像转换为灰度图像，通过将待打标的灰度图像上每一个像素点的灰度值变化与对应的输出功率范围匹配，更精确地匹配像素点的灰度值与对应的输出功率，使打标效果更符合用户的需求。智能处理中心通过数据计算形成，尤其可以存在于互联网或者局域网，也可以存在于本地或者远端，从而实现数据存储、查询、计算。
参照图12，示出了本申请的一种打标方法实施例的步骤流程图，其中，使用打标平台进行打标，所述打标平台包括相连的智能处理中心和智能机打标终端；所述智能处理中心设置有材料信息与对应功率范围的匹配关系表；
值得注意的是，匹配关系表也可以设置在本申请第一实施例的控制主板中，即激光打标机的控制主板可以存储有上述的匹配关系表。

其中所述步骤101可以包括子步骤：
S11，所述智能处理中心获取由所述智能机打标终端分析到的打标材料信息。
打标平台是一种智能激光打标系统，其包括智能机打标终端和作为处理核心的智能处理中心。智能机打标终端负责分析需要打标的材料，以及，接收相关参数后进行打标；智能处理中心负责接收待打标的图像并对图像进行图像处理，以及，根据智能机打标终端分析得到的材料类型在预设的材料信息与对应功率的匹配关系表中搜索相应的功率范围信息。最后根据图像处理的结果以及对应材料的功率范围信息得到需要的打标参数。
待打标的灰度图像上不同的像素点有不同的灰度值，从0-255灰度值对应输出功率也不同，例如，输出功率可以与灰度值具有成比例的关系，打标灰度值为30的像素点所需要的输出功率为打标灰度值为60的像素点所需要的功率的一半。之后，在对应输出功率与材料匹配时，每一种材料匹配一段功率范围，在确定了材料匹配的输出功率范围后，在输出功率范围内，进一步匹配待打标的灰度图像上每一个像素点的灰度值对应的输出功率，更精确地实现像素点的灰度值与对应的输出功率的匹配。如下表格所示：
Figure PCTCN2015091203-appb-000001
举例来说，根据上述表格，如果待打标的材料为塑料，可以确定灰度值为30的像素点所需要的输出功率为1w，而灰度值为60的像素点所需要的输出功率为2w。如果待打标的材料为金属，则灰度值为30的像素点所需要的输出功率为5w，而灰度值为60的像素点所需要的输出功率为10w。上述示例和表格仅为举例说明之用，在应用时，可以将灰度值范围划分为更细的区间，并为每个区间设置更具体对应的输出功率。举例来说， 当待打标的材料为塑料，可以将表格设置为灰度值0-1对应的打标功率为0.02w，灰度值1-2对应的打标功率为0.04w等等。
需要说明的是，在本申请实施例中，所述匹配关系表的获取方式包括：
通过用户的需求设置，和/或，通过云计算分析得到。
对于怎样选择与待打标的材料对应的激光输出功率，在本申请中，智能处理中心设置有材料信息与对应功率范围的匹配关系表，通过查找匹配关系表即可得到对应的激光输出功率范围。材料与其所对应的功率范围可以通过用户实际使用时的打标效果决定，或者，通过云计算对大量材料打标效果的分析，可以得到各种材料对应的功率范围。同一待打标材料时，灰度值与输出功率的关系并不限定为上述举例中的线性相关。

步骤201，智能处理中心接收到待打标图像；
步骤202，智能处理中心将待打标图像经过图像处理转换为灰度图；
步骤203，根据打标材料以及每个图像像素点(x，y)对应的灰度值，查找出所对应的激光器功率p，并进行参数设定(x，y，p)；
根据打标物件材料金属(不锈钢)外壳以及每个图像像素点(x，y)对应 的灰度值，查找出所对应的激光器功率p，并进行参数设定(x，y，p)。例如在x＝100，y＝100即像素(100，100)位置，灰度值是50，通过判别查找智能处理中心库中材料为金属(不锈钢)，值为50所对应设定的激光器功率p＝1000mw，则将该对应像素点的参数(100，100，1000)发送到智能机打标终端。
步骤204，智能机打标终端根据该像素点的参数(x，y，p)将该像素点打标到物件材料上。
智能机打标终端根据该像素点的参数(100，100，1000)，将该像素点打标到物件材料上，依次其他像素点根据打标原理最终将一幅图打标到该金属(不锈钢)外壳上。

对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
本发明第四实施例提出一种激光打标方法，如图16所示，其中，使用激光打标机进行打标，激光打标机通过控制平台进行控制，该控制平台可以是如第一实施例中集成在激光打标机中的本地的控制主板，也可以是如第二和第三实施例中的远端的服务器或智能处理中心。当控制平台为激光打标机本身的控制主板时，该控制主板可以实现存储、运算、控制等功能，可以控制激打标机的激光器和振镜的元件进行打标操作；当控制平台为远端的服务器或智能处理中心时，该控制平台可以与激光打标机中的控制主板通过信号连接。
所述激光打标机包括：控制主板、分别与控制主板通过信号相连的激光器和振镜；所述振镜用于采用预设的移动速度基于目标图像像素点的坐标进行位移；所述激光器用于输出激光；本实施例中的激光打标方法具体可以包括如下步骤：
