Abstract

提供一种在收纳电子部件等的树脂成形品的通气孔上可靠地安装防液性的过滤器的方法，和在该方法中使用的热加工、热熔敷焊头以及成形品。在形成于热塑性树脂成形品(13)的通气孔(16)的入口或出口内使用热加工焊头(22)形成放入过滤器(18)的用的过滤器安装面(14)，并在该安装面(14)的周围形成过滤器固定肋(15)。接着，将多孔的过滤器(18)放入所述过滤器安装面(14)，并使用热熔敷焊头(2)将所述过滤器固定肋(15)熔融而使该熔融的树脂在过滤器(18)的周缘部上流动并覆盖该周缘部，同时，使熔融的树脂渗透到过滤器(18)的壁部内。其后，将渗透的熔融树脂和覆盖过滤器(18)的周缘部的熔融树脂冷却固化，从而将过滤器(18)固定于过滤器安装面(14)。

Description

针对在热塑性树脂成形品形成的通气孔的入口或出口的防水 性过滤器的安装方法、过滤器安装部成形用和过滤器安装用 热加工焊头及热熔敷焊头、以及成形品
技术领域
本发明涉及将在确保通气性的同时具有防水性的过滤器安装到在热塑性树脂成形品形成的通气孔的入口或出口的方法、在实施该安装方法时使用的热加工焊头及热熔敷焊头、以及成形品。
背景技术
近年来，伴随着手机、汽车用电子部件的高性能化，这些部件被收纳在热塑性树脂箱体内。
而且，在所述箱体上，在箱体内与外部空气之间设置有通气孔，以防止因温度变化、气压的变化对电子部件造成不利影响。
但是，若对该通气孔放任不管，则雨水会从通气孔侵入箱体内而引起故障，所以在通气孔安装有确保通气性并阻止雨水侵入的过滤器。
另外，由于在所述箱体的情况下小型轻量化的要求强烈，所以对于过滤器逐年使用较薄的产品。
根据如上的观点，作为针对设置于箱体的通气孔的过滤器的安装方法，专利文献1公开了利用热板在热塑性树脂成形品上形成凹部、并将过滤器引入并固定在该凹部内的热熔敷方法。
另外，作为将用于过滤墨水的过滤器向热塑性树脂成形品熔敷的方法，专利文献2公开了将多个固定肋设置在过滤器固定部、并将过滤器外周部固定于过滤器固定部、进而通过对熔敷肋进行模锻而包围并固定过滤器的外周的方法。
而且，作为向防水用树脂制品熔敷固定防水过滤器的方法，专利文献3公开了热铆接方法，将热铆接用肋设置在防水过滤器安装部的周围，并将该肋热变形而使其向内侧变圆并在防水过滤器的周缘部堆积，同时，利用熔敷焊嘴将防水过滤器的周缘部分熔敷并固定于防水过滤器安装部。

发明内容
发明要解决的课题
但是，在上述专利文献1的方法的情况下，过滤器被固定于利用热板形成的凹部，但是由于过滤器的外周部处于没有被固定的状态，所以在使用过滤器时，未被固定的外缘部有时会卷起而断裂、脱落，存在需要在作业时慎重这样的问题。
另外，在上述专利文献2的方法的情况下，利用熔敷接头将过滤器固定在双凸熔敷肋上，并通过外周肋的模锻(按下)将过滤器外周固定，但是伴随着凸熔敷肋顶端的热变形，过滤器的高度也会变化，所以在过滤器面和过滤器的外周有时会产生皱纹。而且，需要熔敷用、模锻用、肋熔化·平面精整用这3种熔敷装置，存在工序数增加并在转换3道工序时产生错位这样的问题。
另外，在上述专利文献3的方法的情况下，外周肋变形而盖住过滤器的外周缘，所以不用担心如专利文献1那样的外缘部的脱落、脱离。但是，由于该方法是将外周肋热变形而使其向内侧变圆并在防水过滤器的周缘部堆积，并且同时利用熔敷焊嘴将防水过滤器的周缘部分熔敷于防水过滤器安装部的方法，所以过滤器需要一定程度的刚性(厚度)，在软质的材料、膜厚薄(0.3mm以下，特别是0.1mm以下的氟基多孔膜)的过滤器的情况下，有时容易产生错位、皱纹而无法确保水密性。
另外，在该情况下，由于最终是以过滤器本身具有熔融性为前提，所以存在无法适用于没有熔融性的材质、或者熔融温度高于成为安装对象的成形品的过滤器这样的问题。
本发明的目的在于，提供一种过滤器的安装方法，在将过滤器安装在热塑性树脂成形品的通气孔上时，特别是在膜厚是0.3mm以下的柔软的过滤器、例如具有没有弹性而随意摆动、因静电而易于粘附在四处等物理性质的过滤器中，能够不出现错位、皱纹就将过滤器准确地固定于其安装部，同时，过滤器不会随时间发生脱落等；并且提供能够高效地进行该安装的过滤器安装部的形成用热加工焊头和过滤器安装用热熔敷焊头；以及在通气口的入口或出口安装有过滤器的成形品。

具体实施方式
在本发明中，热熔敷焊头有如下2种：当对在热塑性树脂成形品设置的通气孔的入口或出口形成过滤器的安装部时所使用的热熔敷焊头，和当将过滤器安装于所述已形成的安装部过滤器时所使用的热熔敷焊头。
实施例
本实施例1涉及技术方案1记载的过滤器的安装方法、以及用于实施该方法的技术方案12和技术方案13记载的热加工焊头及热熔敷焊头。
首先，使用图3、图4对过滤器安装用热熔敷焊头进行说明，热熔敷装置1的热加工焊头2的发热推压面6形成为在其顶端3包围退让孔4，并且在该发热推压面6的内侧突出设置有环状的热加工肋5，在发热推压面6的外周缘还突出设置有窗孔肋7。
此外，所述热加工肋5的高度比所述窗孔肋7高0.5mm(只要在0.1mm以上，可以是与形状相对应的任意的尺寸)。
8、8a是在发热推压面6的里侧的对称位置形成的冷却空气的流出窗口，9、9a是在热加工焊头2的两侧面的对称位置形成的细缝15，10是冷却空气管，11、11a是施加电压用的导线，12是绝缘体，13是热塑性树脂成形品，14是过滤器安装面，15是过滤器固定肋，16是形成于热塑性树脂成形品13的通气孔，17是从所述冷却空气管10吹出的冷却空气，18是成为安装对象的防液过滤器。
需要说明的是，通过在热加工焊头2的顶端的中央设置退让孔4，从而成为发热推压面6的热量不影响过滤器18的结构。
在图4中，在热塑性树脂成形品13的通气孔16的入口和出口形成有过滤器安装面14，在过滤器安装面14的周围形成有过滤器固定肋15，如图6a那样，利用手工作业或自动装载机将过滤器18放入并安置于过滤器安装面14。
此外，本实施例1中的过滤器18是氟树脂(PTFE)多孔体薄膜且t＝0.1mm，
另外，热加工焊头2的热加工肋5的外径是内径是窗孔肋7的外径是热加工肋5的顶端与发热推压面6的阶梯差是0.8mm，热加工肋5的顶端与窗孔肋7的顶端的阶梯差是0.5mm。
熔敷过滤器18的热塑性树脂成形品13由ABS树脂制成，并设置有的通气孔16。
接着，基于图6a～图6f对过滤器18的安装方法进行说明。
图6a是如下状态，将过滤器18放入到形成于热塑性树脂成形品13的通气孔16的入口的过滤器安装面14内，并将热加工装置1的热熔敷焊头2移动到其上方备用。
图6b是如下状态，热熔敷焊头2降下，热熔敷焊头2的推压发热面6与过滤器固定肋15接触，同时热加工肋5的顶端部与过滤器18接触。在此，若从电源装置(未图示)对导线11，11a施加电压，则形成于热熔敷焊头2的顶端的推压发热面6基于电阻而发热。
热熔敷焊头2的加热温度由电源装置控制，但是利用安装在热熔敷焊头2的顶端的热电偶(未图示)也能有效地进行反馈控制。
热熔敷焊头2的加热温度能够根据过滤器18和热塑性树脂成形品13的材质而相应设定，但是需要热熔敷焊头2的加热温度高于热塑性树脂成形品13的熔点50℃以上，且低于过滤器18的熔点。
在实施例1中，热塑性树脂成形品13的材质是ABS树脂且熔点是110℃，过滤器18是多孔材质的聚四氟乙烯且熔点是327℃，热熔敷焊头2的加热温度是260℃。
同时，热熔敷焊头2被未图示的驱动装置相对于成形品13以相应的推压压靠。
接着，如图6c所示，被热熔敷焊头2的推压发热面6一边推压一边加热的过滤器固定肋15从上部开始熔融而沿着推压发热面6向左右扩散，热熔敷焊头2也随之进一步下降。
接着，如图6d所示，下降的热熔敷焊头2的热加工肋5与过滤器18接触。热加工肋5一边推压过滤器18一边加热周围。
此时，由于热加工肋5在下降时(下沉时)对过滤器18施加从其中心向外周方向扩张的力，所以在过滤器18上不会出现皱纹。
过滤器18由于热加工肋5而在热塑性树脂成形品13的过滤器安装面14一边变形成凹状一边下沉，同时，熔融的热加工肋5的树脂渗透到过滤器18的壁部内。
需要说明的是，在该阶段，被加热而熔融的过滤器固定肋15沿着推压发热面6向左右扩散，但是没有达到过滤器18的周缘。
在热熔敷焊头2进一步下降时，如图6e所示，熔融的树脂从过滤器固定肋15的外侧15a到达窗孔肋7，但是由于窗孔肋7的顶端与热塑性树脂成形品13接触，所以熔融的树脂被窗孔肋7堵住，不会流出到窗孔肋7的外侧。
因此，熔融的过滤器固定肋15的内侧15b沿着热加工肋5向下方流动，不久就会覆盖过滤器18的周缘部。
此外，热熔敷焊头2的降下位置是事先设定的，在本实施例1中，其降下位置是热加工肋5与过滤器18的厚度(0.1mm)接触、并将该厚度挤压至一半(0.05mm)的位置。
另外，在该降下位置，窗孔肋7是进入热塑性树脂成形品13中0.3mm的状态。由此，在防止熔融的过滤器固定肋15的外侧15a溢出的同时，在过滤器安装面14的周围借助窗孔肋7的顶端20形成深度为0.3mm的分型槽7a，所以也提高了加工后的美观(参照图6e，图6f)。
通过将过滤器固定肋15的体积(截面积)设定成加工后的体积小于加工前的体积，在热熔敷焊头2的降下位置，熔融的过滤器固定肋15在热加工肋5与窗孔肋7之间施加压力，熔融的树脂渗透到过滤器18内。过滤器固定肋15的加工后/加工前的体积比在90～99％的范围内适当选择，在本实施例1中选为95％。
图2表示熔融的树脂渗透到过滤器18内、且熔融的树脂覆盖在过滤器18的周缘上的状态。
在设定的下降位置经过设定的加热时间后，停止施加电压，同时，如图6e所示，从设置于热熔敷焊头2的冷却空气管10供给冷却空气17，从而该冷却空气17向发热推压面6的里侧喷出，利用该喷出的空气压从内部对包括热加工焊头2的推压发热面6在内的热熔敷焊头2的顶端3进行冷却。
其后，冷却空气17从流出窗口8，8a以及细缝9，9a被放出到热熔敷焊头2的外部。
如此，通过以预先设定的时间将热熔敷焊头2的顶端3冷却，热加工肋5、推压发热面6、窗孔肋7被冷却，且熔融的过滤器固定肋15的外侧15a以及内侧15b固化。而且，渗透到过滤器18内的树脂18a通过冷却而固化，过滤器18利用该渗透的树脂的固化作用也被固定于热塑性树脂成形品13。
其后，停止冷却空气17的供给，并使热熔敷焊头2上升而从过滤器18向上方移开。
其结果为，过滤器18如图6f那样被固定于热塑性树脂成形品13的通气孔16的入口。
图1是过滤器安装后的剖视图。
本实施例如图5a那样，过滤器安装面14是低于热塑性树脂成形品13的面的安装位置，但是在如图5a那样过滤器安装面14与热塑性树脂成形品13的面高度相同、或如图5b那样过滤器安装面14比热塑性树脂成形品13的面高的情况下，也能够同样地进行过滤器的安装。
另外，过滤器18的形状以及过滤器安装部的通气孔16的形状并不限定于圆孔，多边形的情况也能够实施本发明。另外，如图10a所示通气孔16是多个的情况、以及图10b通气孔16是呈大致矩形且有十字型的梁的形状也能够实施化。由该例可知，本发明能够在多种实施方式的通气孔16、过滤器18中实施化。
本实施例2是关于技术方案12记载的过滤器的安装部形成用热加工焊头和使用该焊头而进行的过滤器安装部的形成方法的实施例。
图7以及图8表示热加工焊头的构造，图9a～图9e表示技术方案2记载的过滤器安装部的形成方法。
需要说明的是，在此，热加工焊头22用于形成过滤器安装部14、过滤器固定部肋15。
图7是过滤器安装部形成用的热加工装置的立体图，图8是热加工装置的中央纵向剖视图，图9a～图9e是形成方法的说明图，附图标记21表示热加工装置整体，附图标记22是热加工焊头。
在该热加工焊头22的顶端的发热面23上突出设置有圆筒状且中空的引导部24，在相比于引导部24的顶端后退的周围接着倒角部25a形成有过滤器安装面形成部25b，并且在所述发热面23的外周26、即相比于过滤器安装面形成部25b后退的位置形成凸缘27。
在所述引导部24的顶端设置有R0.3、在外周是2°的锥面，能够将热加工焊头22顺利地插入到热塑性树脂成形品13的通气孔16内而容易地对热加工焊头22定位。
附图标记8、8a是在发热面23的里侧的热加工焊头22的侧面的对称位置形成的冷却空气的流出窗口，9、9a是在热加工焊头22的侧面的对称位置形成的纵向切开的细缝，10是冷却空气管，11、11a是施加电压用的导线，12是绝缘体，13是热塑性树脂成形品，16是形成于热塑性树脂成形品13的通气孔，17是所述图9d中在利用热加工焊头22熔融并形成过滤器安装部后，为了将冷风吹向该熔融的部分而使其冷却固化而从冷却空气管10吹出的冷却空气。
接着，基于图9a～图9e对过滤器安装部的加工方法进行说明。
图9a是将热加工焊头22的引导部24插入到热塑性树脂成形品13的通气孔16的状态。在此，若从电源装置(未图示)对导线11，11a施加电压，则形成于热加工焊头22的顶端的发热面23基于电阻而发热。
同时，热加工焊头22被未图示的驱动装置相对于成形品13以相应的推压压靠。
在引导部24的锥面部的根部，其与倒角部25a的分界部的直径与通气孔16的直径相同。而且，由于引导部24越靠近顶端越从发热面23离开，所以温度不会上升。
因此，若与倒角部25a接触的通气孔16的肋的周缘部分开始熔融，则其沿着倒角部25a的梯度被推压流向过滤器安装面形成部25b一侧，然后继续加热使与过滤器安装面形成部25b接触的部分熔融，但是树脂不会在引导部24的顶端方向上流动，而是如图9b所示被压出到过滤器安装面形成部25b的外侧。
因此，在通气孔16上不会产生毛刺，能够防止因毛刺而引起的、异物向通气孔16内的混入。
在热加工焊头22进一步下降时，热加工焊头22的过滤器安装面成形部25b在通气孔16的入口的周围向成形品13的表面下沉，如图9c所示，加热熔融了的树脂被压出到外周26一侧而隆起，不久如图9d所示，隆起的树脂的顶端到达凸缘27。
这样，下沉到通气孔16的周围的热加工焊头22一边将其下沉量的树脂熔融一边将熔融的树脂向周围压出，并形成过滤器安装面形成部25b，同时，利用外周26以及凸缘27在通气孔16的入口形成过滤器安装部(过滤器放入台阶部)14和过滤器固定肋15。
热加工焊头22的降下位置是事先设定的，在本实施例2中，其降下位置是过滤器安装面形成部25b和过滤器固定肋15形成为设计尺寸的位置。
在设定的下降位置经过设定的加热时间后，停止施加电压，同时，如图9d所示，从设置在热加工焊头22内的冷却管10供给冷却空气17，从而该冷却空气17向发热面23的里侧喷出，利用该喷出的空气压从内部对包括热加工焊头22的发热面23的里侧在内的热加工焊头22的顶端进行冷却。
其后，冷却空气17从流出窗口8，8a、细缝9，9a以及引导部24的孔被放出到热熔敷焊头2的外部。
如此，通过以预先设定的时间将热加工焊头22的发热面23冷却，引导部24、倒角部25a、过滤器安装面形成部25b、外周26、凸缘27被冷却，且熔融而隆起的树脂成为在俯视观察时呈环状的过滤器固定肋15而固化。其后，停止冷却空气17的供给，并使热加工焊头22上升而将热加工焊头22从热塑性树脂成形品13移开。
其结果为，如图9e那样，在热塑性树脂成形品13的通气孔16的入口的周围形成过滤器安装面14和过滤器固定肋15。
以上是对过滤器安装部进行成形的热加工焊头22的结构和过滤器安装部的成形方法。
如此，相对于形成的过滤器安装部，使用实施例1记载的热熔敷焊头2安装过滤器18。
此外，在本实施例2中，热塑性树脂成形品13的材质是ABS树脂，且热加工焊头22的温度设定为260℃。
图10a是描述在将多个通气孔16设置于成形品13的情况下，利用一枚过滤器18将该多个通气孔16一并覆盖，并利用过滤器固定肋15对其进行固定的例子的样子的图，图10b是描述通气孔16在成形品13中形成为格子状的情况的实施例的样子的图。
