Description

零件感测焊头
技术领域
本公开涉及超声波焊接焊头，更具体地涉及零件感测焊接焊头。
背景技术
本节提供与本公开相关的背景信息，其并不一定为现有技术。
已表明超声波能量在从功率很低的医学诊断到改变材料状态的高强度工艺的各种各样的应用中是一种有用的工具。塑料、特别是热塑性塑料的结合是这种技术的一种特别有用的应用。已证明热塑性塑料的超声波焊接即使未全部也大部分消除了这些问题。事实上，塑料的超声波焊接已变成由通知设计和制造工程师进行选择的工艺。应用的数量和降低的操作费用已引起对热塑性塑料应用超声波焊接的广泛使用。
由于第一台用于塑料的超声波焊机开发于1960年，所以已经存在显著的技术进步，这些进步已使该工艺成为一种实用的生产工具。早期的电源，其采用了真空管技术，不能够产生高功率水平的超声波能量并且是低效和昂贵的。早期的工作局限于表明了工艺前景并刺激进一步的技术开发的研究和开发。时至今日，超声波能量一般来说是一种完善的工业工具，应用于非破坏性的试验、工业超声波清洗、超声波塑料结合和超声波金属焊接中。超声波塑料焊接为用户提供了许多优点，包括速度、效率、优良的焊接质量、消耗品的免除、长的工具寿命以及自动操作能力。
通常，超声波能量为机械振动能量，其运行于超过可听声音的频率或18,000Hz(18,000Hz为正常人听觉范围的上阈值)。取决于应用，一般使用四种基本频率：15,000Hz、20,000Hz、30,000Hz和40,000Hz。基于所需的功率水平选择所需的振幅和将使用的超声波工具的尺寸。频率是重要的，因为它直接影响可获得的功率和振幅以及工具尺寸。在较低的频率更容易产生和控制高功率水平。而且，超声波工具为谐振构件，其尺寸与它们的运行频率成反比。超声波能量的产生始于通过固态电源将常规的50或60Hz电力转换成15,000、20,000、30,000或40,000Hz电能。
超声波焊接可用于各种各样的应用中，包括结合由多种材料和尺寸制成的零件。此外，这种超声波焊接可用于结合各种自动操作。目前，日渐希望进一步自动化超声波焊接工艺，并且为此已尝试使用复杂的成像系统来检测待焊接的零件的存在。这些成像系统可包括光学检测器和处理设备以在视觉上确定焊接装置。因此，成像系统通常相对于超声波焊接焊头的纵向轴线成一定角度安装。这样，成像系统可检测希望的部分并提供用于处理的反馈。
然而，由于要焊接的零件变得越来越大，超声波焊接焊头的尺寸变得越来越大，或可获得的空间变得更加有限，所以使用离轴检测系统不可能提供充分的操作利益。此外，这种成像系统的复杂性和成本对于大多数应用来说是不利的。再者，这种成像系统经常无法提供可靠的操作和功能。因此，在相关领域中需要提供一种用于超声波焊接应用的简化的传感器系统。
发明内容
本节提供本公开的概述，并非其完整范围或其全部特征的全面公开。
根据本教导内容的原理，提供一种用于将第一零件超声波焊接到第二零件上的波节感测焊头，其具有有利的结构。该波节感测焊头包括波节焊头、形成在该波节焊头内的空腔以及至少部分布置在该空腔内的感测装置。该感测装置感测第一零件的诸如存在和/或取向之类的特性并响应所述感测而输出感测信号。
进一步的应用范围将从本文所提供的描述而变得明显。此概述中的描述和特定实例只是出于说明的目的并且不意图限制本公开的范围。
附图说明
本文所述的附图仅仅是为了说明所选实施方式而不是所有可能的实施方案，并且不意图限制本公开的范围。
图1是具有根据本教导内容的原理的波节感测焊头组件的超声波焊机的示意图；
图2是本教导内容的波节感测焊头的横截面图；以及
图3是波节感测焊头组件的端视图。
附图的全部几个图中相应的参考标号表示相应的零件。
具体实施方式
现将参考附图更充分地描述示例实施方式。提供示例实施方式以便本公开内容将变得详尽，并且这些实施方式将充分地将范围传达给本领域技术人员。阐述了许多特定细节，例如特定构件、设备和方法的实例，以提供对本公开的实施方式的详尽的理解。对于本领域技术人员来说将显而易见的是，不一定要采用特定细节，示例实施方式可以以多种不同的形式来实施，并且两者都不应当被解释为限制了本公开的范围。
文中所用的术语只是为了描述具体示例实施方式且并非意图进行限制。如文中所用，单数形式“一”、“一个”和“该”可意图也包括复数形式，除非上下文清楚地另外指明。术语“包括”、“包含”、“包括”和“具有”是包含性的并因此明确了所述特征、整数、步骤、操作、元件和/或构件的存在，但不排除存在或增加一个或多个其它特征、整数、步骤、操作、元件、构件和/或它们的群组。文中所述的方法步骤、处理和操作不应该被解释为一定要求它们以所说明和示出的具体次序来执行，除非特别确定为执行的次序。还应该理解的是，可采用另外或任选的步骤。
当将元件或层称为“在”、“接合在”、“连接在”或“联接在”另一元件或层上时，它可以直接在、接合在、连接在或联接在其它元件或层上，或者可存在介于其间的元件或层。相反，当将元件称为“直接在”、“直接接合在”、“直接连接在”或“直接联接在”另一元件或层上时，可能不存在介于其间的元件或层。用来描述元件之间关系的其它用语应当以相似的方式解释(例如，“在某某之间”与“直接在某某之间”、“邻近”与“直接邻近”等)。如文中所用，术语“和/或”包括一个或多个相关的所列物品的任何一者或全部组合。
虽然术语“第一”、“第二”、“第三”等在文中用来描述各种元件、构件、区域、层和/或部分，但是这些元件、构件、区域、层和/或部分不应当受这些术语限制。这些术语可仅用来将一个元件、构件、区域、层或部分与另一区域、层或部分相区分。术语如“第一”、“第二”和其它数值项当在文中使用时并不意味顺序或次序，除非上下文清楚地指明。因此，下述第一元件、构件、区域、层或部分可叫做第二元件、构件、区域、层或部分而不脱离示例实施方式的教导内容。
文中为了描述的容易性可使用空间上相对的术语，例如“内”、“外”、“下方”、“下面”、“下”、“上方”、“上”、“近端”、“远端”等，以描述如图所示的一个元件或特征与另一元件或特征的关系。除了图中所示的取向以外，空间上相对的术语还可意图包含设备在使用或操作中的不同取向。例如，如果将图中的设备倒过来，那么描述为在其它元件或特征之“下”或“下方”的元件将定位成在其它元件或特征之“上”。因此，示例术语“下”可包含上下两种取向。设备可为其它取向(旋转90度或在其它方向)并且相应地解释文中所用的空间上相对的描述语。
参考附图，并且尤其在图1中，示意性地示出了超声波半波长谐振器100，其具有用于对谐振器加电的装置，例如发电机110。半波长谐振器的特征在于在输入面和输出面二者处的纵向运动的波腹区域和纵向运动的中间波节区域。发电机110将线性电压转换成预定的高频电信号。该预定频率通常在1与100千赫兹之间的范围内，优选在15与60千赫兹之间的范围内。来自发电机110的电信号被提供给电声转换器112，该电声转换器112将在其输入端作用的电能转换成在转换器的外表面显示的预定频率的机械振动运动。在需要时，电声转换器112可为常规的设计。转换器还可按照授予Holze、Jr.的申请日为1982年2月9日的名称为“带斜槽的超声波谐振器(焊头)(Ultrasonic Resonator(Horn)with Skewed Slots)”的美国专利No.4,315,181的教导内容构成。虽然电声转换器112优选为电声转换器，但可使用磁致伸缩转换器。
仍参考图1，随后可将电声转换器112可操作地联接在膜片114或增压器114上，该膜片或增压器114经由螺柱(未示出)而将机械振动运动从电声转换器112传输至焊头10，以进行根据本教导内容的原理的超声波焊接。参考图2-9，焊头10被示出为波节感测焊头。本教导内容的波节感测焊头的设计为操作人员提供了简单而又可靠的装置以感测物品如加工零件、盖子或其它物品的存在而无需结合昂贵而又复杂的成像系统。此外，如将描述的那样，本教导内容的零件感测焊头组件10形成了用于超声波焊接的可靠、安全而且有用的组件。在一些实施方式中，零件感测焊头组件10由钛制成，尽管可预期其它材料。
为此，如图2和图3所示，零件感测焊头组件10包括大致圆柱形波节焊头12，其结束于安装面14。安装面14包括常规的安装系统，其用于可操作地将零件感测焊头组件10联接在增压器114或转换器112上以允许将机械振动能量传输至零件感测焊头组件10。应当理解的是，零件感测焊头组件10可具有限定出用于接合待焊接零件的接触面16的任何希望的形状。
如图2所示，零件感测焊头组件10还包括布置在大致圆柱形波节焊头12的一部分内的感测组件30。具体地，在一些实施方式中，零件感测焊头组件10布置在形成在波节焊头12中的空腔32内。空腔32可包括远端部分34、近端部分36和通气部分38。台肩区40可延伸于近端部分36与远端部分34之间。此外，在一些实施方式中，台肩区域42可延伸于远端部分34与通气部分38之间。台肩区40可包括大致平直面44，其将在下文中被更详细地描述。虽然空腔32如上述包括一连串的圆柱形部分，但是应当理解的是，可预期其它形状、横截面轮廓和安装界面，包括矩形横截面、椭圆形横截面、花键界面、螺纹界面等。
仍参考图2，在一些实施方式中，零件感测焊头组件10还包括容纳在波节焊头12的空腔32内的衬套部件50。衬套部件50可包括远端部分52、近端部分54和延伸于它们之间的过渡部分56。取决于空腔32的形状和横截面轮廓，远端部分52、近端部分54和过渡部分56可定尺寸和成形成以预定构造与空腔32相匹配。例如，在所示的实施方式中，衬套部件50可包括大致圆柱形近端部分54，其以压合构造容纳在空腔32的近端部分36中。为此，衬套部件50的近端部分54可在过渡部分56(呈台肩形式)与其端部58之间限定出一长度，该长度小于空腔32的近端部分36的长度。这样，可确保衬套部件50的过渡部分56可正确地接合空腔32的台肩区40，以防止在端部58未接合台肩区42的情况下衬套50意外地沿着波节轴线NA(参见图2)相对于波节焊头12平移。
在一些实施方式中，为了确保衬套部件50与波节焊头12的正确接合，将衬套部件50的近端部分54定尺寸成如上所述使衬套部件50固定地保持于波节焊头12，而将衬套部件50的远端部分52定尺寸成与空腔32的远端部分34分开，从而衬套部件50与波节焊头12之间的任何保持力都局限于衬套部件50的近端部分54与空腔32的近端部分36之间的界面。
仍然参考图2，衬套部件50的远端部分52可限定出内部空间60，其定尺寸成足以将感测装置70保持于其中。在一些实施方式中，感测装置70包括开关或传感器部件72(文中统一描述为“开关部件72”)，其经由线路72如电线而电联接至感测控制器74(图1)。应当理解的是，在一些实施方式中，感测装置70可包括无线传送器，其可操作地联接至开关部件72以与感测控制器74进行无线通信。为此，无线传送器(未示出)可以可操作地联接至开关部件72，并且在一些实施方式中，保持在波节焊头12内或附近并由电源供电以输出感测信号。类似地，感测控制器74可包括用于接收感测信号的无线接收器。
在一些实施方式中，如图2所示，线路76可大致沿着波节轴线NA从内部空间60内的开关部件72延伸至穿过衬套部件50的近端部分54和波节焊头12的近端部分36形成的贯通通道78并延伸至感测控制器74。为此，在一些实施方式中，可使用绝缘装置80来使线路76与衬套部件50和/或波节焊头12电绝缘。
在一些实施方式中，开关部件72可包括通常将常规的开关机构容纳于其中的开关本体82。开关本体82可限定出螺纹外表面(未示出)以啮合地接合锁紧螺母84或其它调节装置。可采用锁紧螺母84来将开关部件72主动定位在相对于波节焊头12的接触面16的预定深度。也就是说，当处于初始位置时，可调节锁紧螺母84以使开关部件72以长度L平移至一个位置使得开关部件72的可接合部分86延伸至超过接触面16的远端位置(图2)，但是可压缩或以其它方式收缩至接触位置，其中开关部件72的可接合部分86在空腔32和/或内部空间60内受到保护。应当理解的是，可使用其它联接结构来实现提供可操作以检测待焊接零件的存在的传感器的目标，其中该传感器大致从波节焊头的接触面延伸或为其一部分。
在一些实施方式中，开关部件72可为机械开关或传感器、感应开关或传感器、电容开关或传感器、光电开关或传感器、磁开关或传感器、声开关或传感器、电磁开关或传感器、或其它开关或传感器。应当理解的是，使用何种类型的开关或传感器的确定至少取决于操作环境和有待感测的零件。还应当注意的是，可使用开关和传感器的各种组合。
在操作中，零件感测焊头组件10可用来根据已知的超声波技术将第一零件超声波焊接至第二零件。为此，零件感测焊头组件10可定位在待焊接零件上方或大致邻近它。然后可使用常规的操纵机构将波节焊头12移动到焊接位置当中。当波节焊头12正确地定位以进行焊接时，感测装置70，具体而言为开关部件72的可接合部分86，接触待焊接零件。这种接触可使得开关部件72致动，从而使得感测信号输出至感测控制器74。感测控制器74然后可判断用于焊接的适当操作特性，例如待焊接零件的存在，以及在一些实施方式中，其正确取向。如上所述，应当理解的是，至少一部分所列举的操作可因所使用的感测装置70的类型而异(即接触式开关与非接触式开关相比)。
已出于说明和描述的目的而提供了实施方式的以上描述。其并非意图穷尽于此或限制本发明。具体实施方式的单独的元件或特征通常不局限于该具体实施方式，而是在可应用的情况下可互换并且可用于选定的实施方式中，即使是没有具体示出或描述的实施方式。同一实施方式可能在许多方面有所变化。不应该认为这种变型脱离了本发明，并且认为所有这种变型都包括在本发明的范围内。
