技术领域
本申请涉及检测设备技术领域，具体涉及一种刻码质量检测装置及系统。
背景技术
目前，在动力电池加工制造工序中，各机台进出站的数据采集都需要通过扫描如电池顶盖等零部件上的刻码来获取电芯的相关信息，刻码包含有产品序列号等数据信息，因此电池顶盖的刻码质量直接影响到产品的可追溯性和产品的质量稳定性。
相关技术中，电池顶盖等零部件的刻码是通过扫码枪进行扫描，在使用扫码枪进行扫描检测的过程中，扫扫码枪仅能完成电池顶盖的扫描读码，但不能对电池顶盖的刻码质量进行在线检测，而通过物流线中的目检工位实现刻码不良检测时，不仅人力成本较高，且无法实现全面检测，会有漏检现象。
发明内容
鉴于上述问题，本申请提供了一种刻码质量检测装置及系统，用以实现对待检测件上的刻码质量进行在线检测，降低采用人工目检造成错检、漏检的风险。

根据本申请提供的刻码质量检测装置，利用视觉检测系统拍摄并识别检测待检测件的刻码质量，可降低人工检测成本，并可避免采用人工目检的方式导致检测不全面或错检、漏检的情况发生。检测前，通过利用驱动组件驱动视觉检测系统的成像组件沿导向杆上升或下降，以实现成像组件向靠近或远离待检测件的方向移动，使成像组件相对待检测件之间的距离控制在合适位置，从而可保证成像组件能够拍摄出更为清晰的图像，进而可保证利用视觉检测系统对待检测件的刻码质量检测时的准确性。
另外，根据本申请提供的刻码质量检测装置，还可具有如下附加的技术特征：

在本申请的一些实施例中，所述发光件被配置为可选择性发射不同颜色的光。
由于不同类型的待检测件可能具有不同的颜色，因此将发光件设置为可发射不同颜色的光，从而可在成像组件对待检测件的刻码图像时，利用发光件发射与待检测件颜色相匹配的光，以避免待检测件颜色与单一光源造成干扰，从而使得成像组件拍摄的图像更为清晰，进而有助于提高对待检测件的刻码识别检测的准确性。

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
在动力电池加工制造工序中，在如电池顶盖等零部件上通常会利用刻码装置进行刻码，刻码包含有产品序列号等数据信息，各机台进出站的数据采集都需要通过扫描电池顶盖的刻码来获取电芯的相关信息，因此电池顶盖的刻码质量直接影响到产品的可追溯性和产品的质量稳定性。
在扫描刻码时，通常都是采用扫码枪进行扫描，而扫码枪仅能实现对刻码进行扫描读码，当刻码出现歪斜等质量问题时，扫码枪便不能准确扫描读码。因此加工物流线中还会安排技术人员采用人工目检的方式检测刻码质量，人工目检的方式不仅中间人员成本高，且无法实现全面检测，还会出现错检、漏检等风险。
为了解决采用人工目检时人工成本高，且易造成错检、漏检的问题，本申请设计了一种刻码质量检测装置，利用视觉检测系统对待检测件的刻码进行拍摄并识别检测，并通过驱动组件调整视觉检测系统的成像组件的镜头与待检测件之间的距离，从而可实现对不同类型的待检测件的刻码进行质量检测，视觉检测系统的检测精度高，不仅可以降低发生错检、漏检的情况，还可以降低人工目检的人工成本。

第三支撑板与导向杆11可调节固定连接，即第三支撑板41能够沿导向杆11的长度方向发生移动，且能够在移动至合适位置时与导向杆11进行固定。
通过设置与导向杆11可调节固定连接的第三支撑板41，从而可保证发光件43能够在合适高度配合成像组件20发射光源，进而保证成像组件20拍摄的图像更加清晰。
请参见图1和图2，根据本申请的一些实施例，第三支撑板41设有第二导向孔，导向杆11插设于第二导向孔内，且第三支撑板41的一端开设有与第二导向孔相连通的第二松紧槽411；光源组件40还包括：第二松紧调节件，第二松紧调节件贯穿第二松紧槽411的两个侧壁，用于调节第二松紧槽411的松紧度。
第二导向孔为贯穿第三支撑板41的厚度方向的通孔，且第二导向孔与第一导向孔211同轴设置，且第一导向孔211和第二导向孔与导向杆11的尺寸相适配。
示例性的，第二松紧调节件也包括螺柱和螺母。第二松紧槽411的槽口大小也可以适应性调整，具体可以通过第一松紧调节件24拧紧或拧松的方式，来调整第二松紧槽411的两个侧壁之间的距离，以实现第三支撑板41与导向杆11固定连接或解除固定。
通过设置第二松紧槽411，并利用第二松紧调节件调节第二松紧槽411的槽口大小，这样，当发光件43调整至合适位置时，通过拧紧第二松紧调节件，以缩小第二松紧槽411的槽口，便可将第三支撑板41固定在导向杆11的相应位置，从而得以保证发光件43安装固定的稳定性；通过拧松第二松紧调节件，使得第二松紧槽411扩大，便可解除第三支撑板41与导向杆11之间的固定，此时第三支撑板41能够沿导向杆11移动，操作简单、快捷。
根据本申请的一些实施例，发光件43被配置为可选择性发射不同颜色的光。
示例性的，发光件43为发光二极管，且发光件43呈环状，电荷耦合器件23设于发光件43上方，并位于发光件43的轴线上。
由于不同类型的电池顶盖200可能具有不同的颜色，因此将发光件43设置为可发射不同颜色的光，从而可在成像组件20对电池顶盖200的刻码图像时，利用发光件43发射与电池顶盖200颜色相匹配的光，以避免电池顶盖200颜色与单一光源造成干扰，从而使得成像组件20拍摄的图像更为清晰，进而有助于提高对电池顶盖200的刻码识别检测的准确性。
请参见图1和图2，根据本申请的一些实施例，还包括：位置显示器50，位置显示器50设于驱动件与挡板13之间，并与丝杆32螺纹连接，用于显示电荷耦合器件23的高度。
示例性的，位置显示器50为具有读数功能的位置显示器50，当然，也可以是具有语音播放功能的位置显示器50。
利用位置显示器50能够实时检测并显示电荷耦合器件23的高度，则通过记录检测不同类型的电池顶盖200时电荷耦合器件23的高度信息，从而便于在更换待检测电池顶盖200的类型时，快速找到与该类型电池顶盖200相匹配的电荷耦合器件23的高度信息，并将电荷耦合器件23快速调整至该高度。
请参见图1，根据本申请的一些实施例，导向杆11的数量为两个，两个导向杆11相对挡板13的中线对称设置。
具体的，两个导向杆11对称设置于丝杆32的两侧，第二支撑板21上的第一导向孔211和第三支撑板41上的第二导向孔均为两个，两个导向杆11依次对应插设于两个第一导向孔211和两个第二导向孔内。
通过将两个导向杆11相对挡板13的中心对称设置，可提高支撑组件10支撑作用的稳定性和可靠性，且有助于提高成像组件20沿导向杆11的长度方向往复运动时的稳定性。
根据本申请的一些实施例，参见图1至图3，本申请提供了一种用于电池顶盖200的刻码质量检测装置100，包括支撑组件10、成像组件20、光源组件40和驱动组件30。其中，支撑组件10包括两个平行且间隔设置的导向杆11和分别设于导向杆11上端和下端的挡板13和第一支撑板12，两个导向杆 11相对挡板13的中线对称设置，并沿高度方向延伸；成像组件20包括与导向杆11活动连接的第二支撑板21、与第二支撑板21相连的CCD相机231和镜头232；光源组件40设于成像组件20下方，并与导向杆11可调节固定连接，用于提供光源；驱动组件30包括设于挡板13上的转动手轮31、与转动手轮31相连并沿高度方向延伸的丝杆32和与丝杆32螺纹相连的螺帽，螺帽与第二支撑杆相连，用于在驱动件驱动丝杆32转动时，带动成像组件20沿丝杆32上升或下降。
具体地，在检测前，先利用驱动组件30带动成像组件20沿导向杆11上升或下降，以调整成像组件20与电池顶盖200之间的距离至合适距离，然后相应调整光源组件40与电池顶盖200之间的距离，使光源组件40配合成像组件20提供合适光源，以便成像组件20能够拍摄出更为清晰的刻码图像，进而保证对刻码质量检测的准确性。在检测时，成像组件20的CCD相机231和镜头232将拍摄的电池顶盖200上的刻码图像发送至视觉检测系统的图像检测软件，图像检测软件通过将成像组件20拍摄的刻码图像与预设的刻码图像进行比对分析，从而可检测出电池顶盖200的刻码质量是否合格。产品整体结构简单，易于操作，且能够提高对电池顶盖200的刻码质量检测的准确性，避免采用人工目检导致的无法全面检测或错检、漏检的情况发生，并降低了采用人工目检时的人力成本。
根据本申请的一些实施例，本申请还提供了一种用于电池顶盖200的刻码质量检测系统，包括：工控机；输送装置，用于输送电池顶盖200；刻码装置，用于在电池顶盖200上刻码；如上述实施例中任一项的刻码质量检测装置100，设于刻码装置的下游，刻码质量检测装置100的视觉检测系统与工控机电连接；移除装置，移除装置设于刻码质量检测装置100的下游，并与工控机电连接，用于将电池顶盖200从输送装置上移除。
根据本申请提供的用于电池顶盖200的刻码质量检测装置100，利用输送装置输送电池顶盖200，刻码机构对电池顶盖200进行刻码后，输送装置将刻码后的电池顶盖200输送至刻码质量检测装置100的成像组件20下方，当视觉检测系统检测到电池顶盖200的刻码图像与预设的标准刻码图像不一致时，工控机控制移除装置将电池顶盖200从成像组件20下方移除，然后再进行下一检测工序，从而可实现生产线的自动化运行。
