一种焊接头盔(12)，所述焊接头盔(12)能够提供表征来自相关联的焊接操作的信息的图像，其中所述图像出现在与焊接工作区域相同的聚焦范围内。

Description

具有一体的用户界面的焊接头盔
技术领域
本发明大体涉及用于焊接的设备，并且特别涉及一种基于焊接头盔的焊接系统。
背景技术
焊接是在各种产品和结构的加工和构造中的重要工艺。焊接的应用分布广泛并且遍及全世界被使用，例如，列举几例来说，船舶、建筑物、桥梁、车辆和管道的建造和维修。可以在各种各样的地点执行焊接，比如在采用固定焊接操作的工厂中，或在采用手提式焊接机(welder)的现场。
在手动或半自动的焊接中，用户/操作者(例如焊接工)引导焊接设备来产生焊缝。例如，在电弧焊接中，所述焊接工可以手动地定位焊条或焊丝，并且在焊接位置处产生生成热的电弧。在这种类型的焊接中，焊条离开所述焊接位置的间距与被生成的电弧有关，并且与母体金属和焊条或焊丝金属的最佳的熔化/熔合的实现有关。这样的焊缝的质量通常直接依赖于焊接工的技能。
焊接工一般在焊接时依靠各种各样的信息。这种信息包括，例如，电流和电压。传统地，焊接工将需要查看所述焊接设备的控制面板上的仪表来获得这种信息。这将要求焊接工引导他们的视野远离焊接工作区域，而这样是不合乎期望的。
在过去，已做出努力来在焊接期间给焊接工提供信息，比如在美国专利No.4,677,277中公开的方法中，其中电流和电压被监控来生成关于电弧焊接中的电弧状态的音频指示给操作者。然而，仅由音频电弧参数指示器组成的监控器难以听到和干预，并且不能够实现合乎期望的精密控制和通常所要求的焊接质量。
最近，如美国专利No.6,242,711中公开的，用于监控电弧焊接的装置已被开发，所述用于监控电弧焊接的装置给焊接工提供焊接电弧的实时的电压和电流状态，其中，信息以灯、照明的条形图、光投影、照明的透明显示或相似的形式被置于戴头盔的操作者的视觉范围之内，并且被定位于接近所述头盔中的头盔观看窗。
然而，在此装置中，焊接工仍必须移动他们的视觉焦点远离所述焊接工作区域，以便专注于被定位于接近焊接窗的信息，或者焊接工必须接受周边的信息，同时继续专注于所述焊接工作区域。
由此，本发明的目的之一是提供焊接头盔和系统，所述系统允许焊接操作者考虑关于所述焊接过程的信息，而不从所述焊接过程分散注意力。
发明内容
本发明提供一种焊接头盔，所述焊接头盔能够提供表征来自相关联的焊接操作的信息的图像，其中所述图像与焊接工作区域出现在相同的聚焦范围内，并且本发明提供一种包括所述头盔的焊接系统。
从以下的具体实施方案、附图和权利要求书，本发明的各种方面和特征对于本领域技术人员来讲将变得清晰。
附图说明
图1是根据本发明的焊接系统的原理图。
图2是类似于图1的所述头盔的包括摄像机的焊接头盔的放大视图。
图3是类似于图2的所述头盔的包括投影仪的焊接头盔的剖视图。
图4是类似于图3的所述头盔的包括集成的视频显示器的焊接头盔的剖视图。
图5是类似于图2的所述头盔的包括双目摄像机的焊接头盔的立体图。
图6是类似于图5的所述头盔的示出双目观看屏的焊接头盔的内部视图。
具体实施方式
现参照附图，图1中图示说明焊接系统10。所述焊接系统10包括焊接头盔12、焊接系统14、焊接枪16和工件18。所述工件18大体地限定焊接工作区域20，在所述焊接工作区域，所述焊接枪16可以被用来形成焊缝。
所述焊接系统14包括用于产生焊接电流和焊接电压的焊接设备、用于控制所述焊接电流和所述焊接电压的焊接控制系统，以及用于监控所述焊接电流和所述焊接电压的监控系统。所述监控系统还可以监控各种各样的其他的操作参数，比如但不限于，焊丝送进速度、已使用的焊丝量/剩余焊丝量、操作者所期望的任何类型的焊接反馈以及任何其他合乎期望的操作参数。
所述焊接头盔12包括主体22，所述主体具有被连接到所述主体22的视觉显示器24。所述显示器24可以是一窗，所述窗包括焊接镜、视频监控器(比如LCD显示器或LED阵列)或适于允许焊接工看到所述焊接工作区域20的任何其他装置。所述视觉显示器24可以是有源的或无源的，和/或可以允许所述操作者通过所述视觉显示器24看到所述焊接工作区域20。必须理解的是，在所述显示器24是一视频监控器的这样的一实施例中，视频处理可以被利用来增强所述焊接操作的画面。进一步地，可以可选地包括记录装置来记录并且之后为分析和/或评估来回放焊接操作。
如图2中最佳地示出的，焊接头盔12可以包括摄像机26，所述摄像机26被安装在或接近所述焊接工的视点处(point of view)。在所述视觉显示器24是一视频监控器的所述实施例中，所述摄像机26可以将所述焊接工作区域20的视频画面提供给所述显示器24。
如图3和图4示出的，信息产生装置28与所述焊接系统14的所述监控系统通信，并且能够基于所述被监控的焊接参数(比如电流和电压)在所述视觉显示器24上产生表征来自于所述监控系统的信息的图像，其中所述图像的焦点在相关联的焊接工作区域的一聚焦范围上，例如，在所述焊接头盔12的所述主体22的之外。例如，所述图像可以是符号、字母数字或适于指示所述信息的任何其他图案。因此，焊接工可以查看表征关于焊接操作的信息的图像而不从所述工作区域移除焦点。因此，在至少一个实施方案中，所述焊接工可以同时专注于所述工作区域和信息的所述图像。
必须理解的是，除其他类型的信息之外，，基于焊接电流和焊接电压的所述信息连同各种各样的其他参数包括，但不限于，焊接电流反馈、焊接电压反馈、焊接设备的控制设置、焊接过程的统计信息、包括能力表征的基准或限制、包括材料短缺或低流量的报警、预定的或合乎期望的焊缝的表征等。
进一步地，在一个实施方案中，所述摄像机26被用来相对于所述焊接工作区域20校准所述图像的深度(the depth of the image)。在另一个实施方案中，在所述焊接枪上的位置传感器可以被用来校准所述图像的所述深度。在特定的应用中，准确对齐所述图像和所述焊接工作区域是非常合乎期望的，以至于在所述图像中被表示的所述信息易于所述焊接工获取(access)，并且以至于在所述图像中的所述信息容易被所述焊接工接受。
在所述视觉显示器24是一视频监控器的所述实施例中，信息产生装置28可以基于所述被监控的参数(比如焊接电流和焊接电压)将表征来自于所述监控系统的信息的图像包括在所述显示器24上示出的所述焊接工作区域20的视频画面中。
如在29处所指示的，所述信息产生装置28可以如期望的那样与其他装置进行有线的或无线的通信。
在图3中，所述信息产生装置28是一投影仪。所述投影仪可以，例如，包括与众多相关联的反射镜32一起的内部LCD显示器或LED阵列30，以将所述产生的图像反射到所述视觉显示器24。所述被反射的图像给予所述图像以相对于所述视觉显示器24的深度显现，并且因此将所述图像放于相关联的焊接工作区域的聚焦范围上且在所述焊接头盔12的所述主体22之外，并且可选地在与所述相关联的焊接工作区域20相同的焦距处。可选地，反射面34可以被置于所述视觉显示器24的一部分上，以便实现合乎期望的量的反射或反射角。在一个实施方案中，提示器(teleprompter)型的技术可以被利用来将所述图像置于所述显示器24或面34上。附加地，必须理解的是，一个实施方案包括使用在所述头盔之内的LCD显示器或其他类似的显示器来产生所述图像，所述图像于是沿光学路径(比如通过反射或光纤光学装置或任何其他合适的装置)被传送，以置于所述图像显示器24或面34。
在图4中，所述信息产生装置28包括被集成到所述视觉显示器24的屏、膜或片36。所述片36可以是半透明的LCD膜，电光膜，或任何其他用于所述信息产生装置28来在所述视觉显示器24中生成被产生的图像的合适媒介。在一种应用中，所述信息产生装置28可以将立体图投影在所述焊接镜上，以至于焊接工的眼睛将分别地查看所述图像来创建深度感，并且因此将所述图像聚焦在所述相关联的焊接工作区域20的聚焦范围上并且在所述焊接头盔12的所述主体22之外。
图5中示出了一种焊接头盔12，所述焊接头盔包括双目摄像机26a和26b。如图6中示出的，这些摄像机26a和26b对应于双目观看屏24a和24b。信息产生装置可以生成一图像，所述图像在所述观看屏24a和24b之一或两者中被产生。在一个实施方案中，除了在所述主体22的相反的侧上之外，所述摄像机26a和26b与所述屏24a和24b被置为成一直线(in alignment with)，因此将给予所述焊接工在摄像机26a和26b正前方的视图。附加地，在具有双目摄像机26a和26b以及双目观看屏24a和24b的实施方案中，生成所述景深感。
在任何情况下，所述图像可以是文本、图表和/或视频反馈的覆盖图。附加地，设想的是，在至少一个实施方案中，上面描述的所述系统可以被用在远程焊接情形中，所述远程焊接情形包括但不被限制于机器人焊接或水下焊接。
尽管对于特定的实施方案，操作的原则和模式已被解释和被图示说明，然而，必须理解的是，除了如具体地被解释和被图示说明的之外，这可以以其他方式被实行，而不背离其精神和范围。从属权利要求都限定所述焊接头盔和包括所述头盔的焊接系统两者的特征。如此所有从属权利要求的所有特征涉及所述头盔本身。
所述焊接区域大体是围绕所述焊接部位的所述区域。所述焊接区域可以是所述电弧的位置或所述工件的延伸范围，和/或可以包括所述焊接枪或所述焊接枪的部件，比如所述焊接枪的尖端或类似按钮的操作装置。
所述焦距或所述聚焦范围可以是当前的，或是手动地或自动地可调节的，特别是依赖于在所述头盔(并且更精确地，一方面是所述头盔的所述视觉显示器)和(另一方面)所述焊接区域之间的距离。在一个实施例中，所述聚焦范围可以是5，10，15，20或30cm，优选地在所述焊接部位附近被定中心，并且在任何情况下包括所述焊接部位，或对应于所述工件的所述延伸范围。在自调节情况下，可以有一距离确定装置，所述距离确定装置被提供在所述头盔上和/或在所述工作区域上。
