S4.对喷涂二维码的样品进行尺寸测量；
S5.将S4步骤所获得的尺寸数据上传至控制端，在控制端内通过对比数据库得到该样品的类型；同时，将该样品的类型信息与S3步骤中所喷涂的二维码信息进行关联。
S5步骤中所述的控制端内部存储有样品标准数据构建的数据库；在接收到待检测样品的长、宽、厚度数据后，与上述数据库中的数据进行对比，找到对应的样品类型，完成样品分类过程。
机械性能样条是常用的一种条状样品，在传统的分类过程中，同样采用人工分类的方式，存在分类速度慢，容易出错的问题。同时，由于样品在分类后，并未喷码，其尺寸是否合格，无法知晓，一般通过人工记录的方式，费时费力，错误率高，而且后期统计困难。
为了解决上述问题，在测量机械性能样条的分类和测量过程中采用本发明所述的方法，可以有效的提升效率，控制错误率，而且后期数据统计方便，大大提升了生产效率。
本实施例还提供了一种前述标准试样尺寸测量方法在测量机械性能样条尺寸方面的应用。
为了满足上述测量方法在实际生产中的应用，本发明特提供一种标准试样尺寸测量***。
如图2～3，所述的一种标准试样尺寸测量***，包括机架1、传送机械手2、上位机3以及设置在机架1上的用于采集样品8的来料信息的扫码组件4、用于对样品进行固定的固定组件5、用于向样品8喷涂唯一的二维码的喷码组件6、用于采集样品8的尺寸数据的测量组件7；其中，所述的上位机3与扫码组件4、 固定组件5、喷码组件6连接和测量组件7均电性连接，并在接收扫码组件4发出扫码完成的信号后，控制传送机械手2将样品8放置在固定组件5进行定位，然后通过测量组件7测量样品8的尺寸后，在上位机3内判断样品8的类型，然后通过传送机械手2将样品8输送到下一个工位，如分类存储箱。
根据实际生产需要，所述的扫码组件4可以是扫码枪401；所述的扫码枪401通过握持在工作人员的手中，对样品8进行扫码，获取样品8的出厂信息，并将该信息存储在上位机3内。
或者，如图4，所述的扫码组件4可以包括扫码单元402、设置在机架1上的门型的扫码支架403；扫码单元402设置在扫码支架403的横梁上；当样本8在扫码支架403下方通过时，扫码单元402获取样本8上的编码的信息，发送至上位机3。样本8可以通过传送带运送并经过扫码单元402，也可以通过人工将样品8放置在扫码单元402下方。
需要明确的是：工作人员进行扫码工序后，样品8通过传送机械手2传送至固定组件5，在该过程中，传送机械手2通过CCD利用像素点进行定位，配合传送机械手2进行抓取。
实施例I：由于在固定组件5进行固定后，需要对样品8进行测量，如果采用的是激光头进行直线扫描测量的方式，则需要对样品8进行固定，以防样品8发生移动，影响测量结果。
在实际工作中，如图5～6，所述的测量组件7可以通过激光测距单元进行样品8的长度、宽度以及厚度的测量；同时，在使用激光测距的过程中，为了保证测量结果准确，样品8通过固定组件5处于静止状态，而测量组件7上的激光测距单元可以直线运动，通过扫描的方式测量样品8的尺寸数据。
具体的，所述的固定组件5包括通过螺栓设置在机架1上的底板501、负压 单元502、定位单元503；其中，所述的底板501的边沿设置有一列至少两个定位单元503且该底板501的中部设置有通风孔；所述的通风孔与负压单元502的输出端连接；其中，所述的定位单元503与传送机械手2上的定位装置进行配合，用于将样品8放置在需要的位置；其中，所述的负压单元502与上位机3电性连接，用于在传送机械手2将样品8放置在指定位置后控制负压单元502工作，将样品8吸附在底板501上。
优选的，如图8～9，所述的底板501上设置有凸起的平面；该平面用于设置样品8；为了适应不同的样品8，如果存在若干细小的通风孔，在负压单元502工作的瞬间，样品8可能发生位置偏移，使测量结果不准确。所以，可以将若干通风孔设置为一个长孔502A；该长孔502A的长度方向与样品8的长度方向一致。在放置时，样品8位于长孔502A的上方，在负压单元502工作时，可以平稳的将样品8吸附，解决了因样品8发生位移，而造成的测量失准的问题。
同时，底板501上设置有凸起的平面，可以使样品8的高度高于机架1的支撑面，方便测量样品8的厚度。而且，该凸起的平面的下方可以设置负压单元502，方便使用密封胶进行密封。
需要明确的是：所述的定位单元503可以是红外发射端；而设置在传送机械手2上的定位装置可以是红外接收端；当红外发射端与红外接收端完全对应后，发送信号至上位机3中，由上位机3发出控制信号控制传送机械手2松开样品8，再控制负压单元502工作通过长孔502A将样品8吸附在底板501上。
其中，上述的测量组件7包括用于测量样品8厚度的第一滑轨机构701、用于测量样品8长度和宽度的第二滑轨机构702以及用于设置第一滑轨机构701、第二滑轨机构702的固定框体703；
其中，所述的固定框体703通过导轨设置在机架1上；该固定框体703垂 直地面的侧面上设置有第一滑轨机构701；固定框体703远离固定组件5的侧面上设置有第二滑轨机构702且该第二滑轨机构702可沿固定框体703作直线运动且第二滑轨机构702的运动方向与固定框体703的运动方向垂直。
上述的第一滑轨机构701、第二滑轨机构702均为直线运动的导轨结构，其结构相同，只是运行方向不同，均包括驱动电机a、第一导轨b、第二导轨c、滑块d、螺杆e以及测量元件g；
其中，如图7，所述的第一导轨b、第二导轨c可拆卸的设置在固定框体703上；第一导轨b、第二导轨c之间间隙设置滑块d；滑块d朝向样品8的一端设置测量元件g且远离样品8的一端设置有螺纹孔；所述的滑块d上的螺纹孔与螺杆e对应设置；螺杆e的一端与驱动电机a的输出端连接，另一端通过轴承座设置在固定框体703上。
实施例II：如图10～11，在实际工作中，所述的测量组件7可以通过CCD进行样品8的长度、宽度以及厚度的测量；由于用CCD对物体进行尺寸测量无需进行直线运动，所以样品8放置在指定位置即可。
为完成CCD尺寸测量，所述的固定组件5包括设置在机架1上的透明的底板501和定位单元503以及照明单元；所述的测量组件7包括CCD线阵704；其中，所述的底板501的边沿设置有一列至少两个定位单元503；其中，所述的定位单元503与传送机械手2上的定位装置进行配合，用于将样品8放置在成像物镜的物方视场中并将CCD线阵像敏面设置在成像物镜的最佳像面位置上，通过照明单元的照明完成测量；其中，所述的CCD线阵704与上位机3电性连接，用于测量样品8的尺寸数据。
在本实施例中，底板501采用透明质物体，如玻璃，样品8由传送机械手2通过定位单元503定位后，放置在底板501上。优选的，CCD线阵704可以设 置在底板501上且位于样品8的相对侧或者设置在固定框体703朝向样品8的一侧，为了方便使用，还可以根据需要设置所需的照明单元。
优选的，CCD线阵704选择两个分设在底板501的两端的两个CCD；采用2个CCD来计算产品的长度，CCD检测：精度是视野/(像素*5)，按照200视野，2000W像素的相机计算得出精度在0.02mm左右，采用2个CCD可以缩小视野进行检测，从而提高检测的精度，为了保证测量的精度，产品需打前光，在放置产品时，需要把毛刺面朝上，防止毛刺对检测的精度有影响。
在安装的过程中，如果需要，可以在机架1上设置横梁1A，用于放置所需的CCD线阵704或者照明单元，可根据实际情况自行调整。
具体实施例III：当然，在具体实施的过程中，还可以采用直线扫描法与CCD线阵704混合使用的方式。
如：所述的固定组件5包括设置在机架1上的透明的底板501和定位单元503以及照明单元；所述的测量组件7包括用于测量样品8长度和宽度的CCD线阵704、用于测量样品8厚度的第一滑轨机构701；
其中，所述的底板501的边沿设置有一列至少两个定位单元503且与传送机械手2上的定位装置进行配合，用于将样品8放置在成像物镜的物方视场中并将CCD线阵像敏面设置在成像物镜的最佳像面位置上，通过照明单元的照明完成测量；其中，所述的CCD线阵704与上位机3电性连接。
同样的，也可以根据需要，设置测量样品8长度和宽的第二滑轨机构702以及测量样品8厚度的CCD线阵704。
与现有技术相比，本发明所述***通过测量组件，将尺寸测量时间由原来平均45s左右测试一根试样尺寸，降到3s-5s测试一根试样尺寸，将尺寸测量效率提高近9-15倍，解决了现有试样测试方式因为尺寸测量效率低下，不能满足 大批量样品测试下低投入的要求。同时，由于采用了合理的分类过程，完成自动分类，可以与后续自动化单元，如压力检测单元进行联动，形成完备的自动化流水线。
需要明确的是：本文所述的喷码组件6可以选择如申请号CN205467924所述的技术方案。
需要明确的是：所述的上位机3可以设置在机架1上，或者根据需要设置在控制室内。
需要明确的是：本文中所述的传送机械手2在传送样品8的过程中，为保护样品8的表面，可采用负压吸盘移动样品8。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易变化或替换，都属于本发明的保护范围之内。因此本发明的保护范围所述以权利要求的保护范围为准。
