一种子母锡炉及包含该子母锡炉的浸锡设备
技术领域
本发明涉及电器元件加工设备领域，具体涉及一种子母锡炉及包含该子母锡炉的浸锡设备。
背景技术
浸锡焊接是电器元件加工领域的常见工艺，其常用于线包飞线和针脚的焊接。现有的浸锡焊接原理主要为将金属锡加热至熔点使其成为液态锡，将元器件的飞线或针脚浸入液态锡中再取出，由于室温低于金属锡的熔点，液态锡迅速凝固从而将针脚焊接于线包上或使飞线焊接固定不易散开。
在进行大规模工业化加工时，对液态锡的需求量极大，往往在焊接一批元器件后，锡炉中的液态锡就大量减少，造成液位下降，而自动化浸锡设备对浸入深度已设定为固定值，当液位下降时，飞线的浸锡段长度就无法保证，针脚甚至会浸不上锡。因此，现有的浸锡设备中的锡炉往往需要较大体积从而以减轻浸锡消耗液态锡造成的液位下降的影响。但是，大体积锡炉一样无法避免大量浸锡造成的液位下降，解决的办法通常只有在进行一定批次的浸锡操作后，加入固态锡，并利用锡炉的自加热功能使固态锡熔解成为液态。这样的方法存在以下明显缺陷：加锡和加热熔解过程中，浸锡操作无法进行，造成了时间的浪费，导致浸锡效率受到极大影响；同时，电器元件对浸锡品质有很高的要求，尤其如锡珠等需严格控制，传统大锡炉浸锡因液面大，易产生锡珠；并且浸锡针脚的排布有可能不规则，针脚附件会有不能浸锡的部件，传统方式大锡炉浸锡会烧伤产品，造成不可修复的损害。因此，人们迫切需要一种浸锡过程中，锡炉中液态锡液位恒定不变、减少锡珠且可控制浸锡范围的设备，以提高设备的工作效率，扩大使用范围，并提高产品的良率。
针对现有浸锡设备的上述缺陷，本发明提出改进的技术方案。

在一种优选的实施方式中，包括并列设置的两个或者两个以上的所述子母锡炉，所述取放机构可在所述驱动装置的驱动下在各所述子母锡炉中进行浸锡操作。
在一种优选的实施方式中，所述驱动装置包括第一滑动机构和第二滑动机构，所述第一滑动机构包括第一滑轨、第一电机、第一传动机构和第一滑动架，所述第一滑轨固定安装于支架上，所述第一电机与第一传动机构传动连接，所述第一滑动架与第一滑轨滑动连接，所述第一传动机构带动第一滑动架在第一滑轨上滑动，所述第二滑动机构包括第二滑轨、第二电机、第二传动机构和第二滑动架，所述第二滑轨固定于第一滑动架上，所述第二电机与第二传动机构传动连接，所述第二滑动架与第二滑轨滑动连接，所述第二传动机构带动第二滑动架在第二滑轨上滑动，所述第一滑轨和第二滑轨相互垂直。

具体实施方式
本发明一个实施例：
如图1所示为本发明一个实施例所述浸锡设备的立体图，其包括支架110，支架110包括一块底板和安装于底板上的立柱，在支架110的立柱上安装有第一滑动机构，所述第一滑动机构包括第一滑轨121，其安装于支架110的立柱上，第一滑动架122滑动连接于第一滑轨121上，为了使第一滑动架122沿第一滑轨121滑动，安装有第一电机和第一传动机构。第一滑动架122与第二滑动机构的第二滑动架132通过第二滑轨131连接，第二电机133通过第二传动机构带动第二滑动架132沿Z轴方向滑动。在第二滑动架132上固定转动机构140，取放机构141可沿转动轴做轴向转动，并用于夹持线包治具。为了美观和检修维护的方便，在支架110上，第一滑轨121的一侧安装有理线盒170，可将设备的部分电缆放入理线盒170中。
如图2所示为本发明一个实施例所述浸锡设备的侧视图，在支架110上安装有母锡炉151用于盛放液态锡，并且在母锡炉151的一侧的支架110上安装有浮动刮锡刀161，气缸162连接浮动刮锡刀161做往复运动，用于刮除锡炉口的凝固的锡。
以下，对子母锡炉和刮锡装置做进一步说明。
如图3所示为本发明一个实施例所述子母锡炉和刮锡装置的立体图，母锡炉151固定安装于支架110上，子锡炉152位于母锡炉151内部，且子锡炉152上安装有顶升装置，保证每次浸锡之前，子锡炉152通过顶升装置沉入母锡炉151的锡液面以下，从而使子锡炉152中充满液态锡，再通过顶升装置将子锡炉152举升出母锡炉151的液面以上，取放机构夹取载有线包的治具浸入子锡炉152的液态锡中进行一次浸锡操作，每次浸锡操作循环上述步骤。此技术方案可消除由于单个锡炉持续消耗液态锡造成的液位下降，并且不需要停机加锡，极大的提高了设备的工作效率。同时，为保证子母锡炉的耐热性能，子母锡炉的材料为钛合金；为方便子母锡炉的清洗和维护，子母锡炉外表面镀有陶瓷层。子锡炉152一侧安装的顶升装置用固定架154固定于支架110上，在母锡炉151开口的平面上设置有浮动刮锡刀161，为最大限度的降低浮动刮锡刀的重量，浮动刮锡刀厚度小于2mm；为了只将母槽中的锡氧化层刮去，节省耗费锡量，节约工厂成本，其材料优选为钛合金或陶瓷中的任意一种，浮动刮锡刀161通过滑杆163连接于气缸162上，气缸162通过底座164固定于支架110上。底座164调整高度，使浮动刮锡刀161与子锡炉152上升后超出母锡炉151液面的高度处于一个平面上，当线包浸锡时，顶升装置提升子锡炉152竖直向上运动，抬升至母锡炉151中液态锡液面以上，此时，气缸162带动浮动刮锡刀161往复一次刮锡，从而刮除子锡炉152中液态锡表面凝固的锡，从而保证线包在浸锡过程中的顺畅。同时，为回收浮动刮锡刀161刮除的锡，在与浮动刮锡刀161同侧母锡炉151上固定安装一锡渣盒165（为了便于操作者清理锡渣，锡渣盒可以设置为可拆卸型，比如，通过卡扣结构直接扣接在母锡炉上）。
如图4所示为本发明一个实施例所述子母锡炉和刮锡装置的侧视图，子锡炉152的顶升装置包括电机153、轴承座156、丝杆158、丝杆副157及举升臂155，在固定架154的上下两端分别固定两个轴承座156，丝杆158套入轴承座156中，丝杆158的一端与电机153的转动轴连接，且电机固定于固定架154下方，同时，为将丝杆158的轴向转动转化为线性移动，在丝杆158上配合安装丝杆副157，在丝杆副157上固定举升臂155，举升臂155与子锡炉152连接，从而实现了电机153带动子锡炉152在竖直方向上运动的目的。为保证子母锡炉在使用中始终处于水平状态，在母锡炉151底面安装水平调节机构，其包括固定安装于母锡炉151下底面矩形四个顶点上的调节螺丝159，调节螺丝159两端分别固定于支架和母锡炉151底面上。在设备使用之前，可通过四个调节螺丝159调节母锡炉151相对于水平面的平面度，保证其处于水平状态，从而防止内部锡液由于倾斜溢出子母锡炉。
以下，对第一滑动机构、第二滑动机构和转动机构的结构做进一步说明。
如图5所示为本发明一个实施例所述第一滑动机构的立体图，两个第一滑轨121安装于支架110两侧，第一滑动架122通过滑动块与第一滑轨121滑动连接，在第一滑轨121上安装有同步轮123，两个第一滑轨121之间的同步轮用转轴125连接，同一第一滑轨121的同步轮之间用同步带124连接，在其中一个同步轮123上安装第一电机，第一电机带动一个同步轮123转动，同时，第一滑动架122固定连接于同步带124上，当同步轮123带动同步带124运动时，同步带124可带动第一滑动架122沿Y轴方向水平运动。
如图6所示为本发明一个实施例所述第二滑动机构的立体图，两个第二滑轨131安装于第一滑动架122的面板1221上，在面板1221的上下两端安装有两个轴承座135，顶部的轴承座135上安装有第二电机133，丝杆134与第二电机133的转轴连接，且丝杆134套入轴承座135中。第二滑动架132与第二滑轨131滑动连接，且为实现丝杆134的轴向转动转化为第二滑动架132的线性移动，在第二滑动架132上安装丝杆副136，从而使第二电机133带动第二滑动架132做Z轴方向滑动。
如图7所示为本发明一个实施例所述转动机构的立体图，转动机构的固定架142固定于第二滑动架132上，且固定架142一端固定有第三电机143，第三电机143连接有一同步轮1451，且各同步轮设置如图所示，同步轮1451和同步轮1452之间用同步带1461连接，同步轮1453和同步轮1454之间用同步带1462连接，固定架142两侧的同步轮1453之间连接有转轴144。在同步轮1454之间轴向固定有取放机构147，用于夹持载有线包的治具，在两个取放机构上部，安装有保护盖141。在第三电机143运行时，利用同步轮、带的传动，使取放机构147和保护盖141做轴向转动。
以下，对取放机构夹持治具时的结构做进一步说明。
如图8所示为本发明一个实施例所述取放机构夹取载有线包的治具的立体图，取放机构147包括转轴1473、动力源1472和夹头1471，将转轴1473连接于转动机构的同步轮1454上，动力源1472可使夹头1471夹持或放开治具191。当夹头1471夹取治具191时，治具191载有多个线包192，且线包192上具有两根互为垂直的飞线，此设备同时只能对一个方向上的飞线进行浸锡作业，当完成一个方向飞线的浸锡时，转动机构带动取放机构147转动一个角度，从而将另一个方向的飞线浸入液态锡中，最终实现多个方向飞线都完成浸锡。
如图9所示为本发明一个实施例所述取放机构夹取载有线包的治具的侧视图，在动力源1472上安装保护盖181，其安装方式为将扣板1821固定于动力源1472上，扣板1822与保护盖181固定连接，再将扣板1821和扣板1822用定位销1823连接，在定位销1823上安装弹簧。安装保护盖181的目的是：由于在高温液态锡与飞线接触时，飞线和液态锡的温度差极易造成炸锡现象，飞溅的液态锡液珠容易溅射到治具191的各个面上从而凝固成为锡点，而在生产线上，对治具191的抓取面精度要求非常高，大量的锡点极易造成抓取治具失败，从而影响产线的正常运行。为此，需要在治具的抓取面安装一保护盖181，从而避免液态锡溅射到治具191的抓取面上。同时，为适应治具夹取时，夹取高度的细微变化，在保护盖181和动力源1472之间连接加入弹簧，保证夹取治具191时，治具191的抓取面始终顶住保护盖181，从而保证贴合性。
本发明另一个实施例：
如图10所示为本发明另一个实施例所述浸锡设备的立体图，其包括支架210，支架210包括一块底板和安装于底板上的立柱，在支架210的立柱上安装有第一滑动机构，所述第一滑动机构包括第一滑轨221，其安装于支架210的立柱上，第一滑动架222滑动连接于第一滑轨221上，为了使第一滑动架222沿第一滑轨221滑动，安装有第一电机和第一传动机构。第一滑动架222与第二滑动机构的第二滑动架232通过第二滑轨231连接，第二电机233通过第二传动机构带动第二滑动架232沿Z轴方向滑动。在第二滑动架232上固定转动机构240，取放机构241可沿转动轴做轴向转动，并用于直接夹持线包。
如图11所示为本发明另一个实施例所述浸锡设备的侧视图，在支架210上沿第一滑轨221方向安装有两个母锡炉251用于盛放液态锡，并且在每个母锡炉251的一侧的支架210上安装有浮动刮锡刀261，气缸262连接浮动刮锡刀261做往复运动，用于刮除锡炉口凝固的锡。
以下，对锡炉和刮锡装置做进一步说明。
如图12所示为本发明另一个实施例所述子母锡炉和刮锡装置的立体图，母锡炉251固定安装于支架210上，子锡炉252位于母锡炉251内部，且子锡炉包括底板2521和浸锡槽2522，在底板2521上安装多个浸锡槽2522，且在底板2521上安装有顶升装置，保证每次浸锡之前，子锡炉252通过顶升装置沉入母锡炉251的锡液面以下，从而使浸锡槽2522中充满液态锡，再通过顶升装置将子锡炉252举升至母锡炉251液面以上，取放机构夹取线包将针脚浸入浸锡槽2522的液态锡中进行一次浸锡操作，每次浸锡操作循环上述步骤。此技术方案可消除由于单个锡炉持续消耗液态锡造成的液位下降，并且不需要停机加锡，极大的提高了设备的工作效率。同时，为保证子母锡炉的耐热性能，子母锡炉的材料为钛合金；为方便子母锡炉的清洗和维护，子母锡炉外表面镀有陶瓷层。子锡炉252一侧安装的顶升装置用固定架254固定于支架210上，在母锡炉251开口的平面上设置有浮动刮锡刀261，为最大限度的降低浮动刮锡刀的重量，为最大限度的降低浮动刮锡刀的重量，浮动刮锡刀厚度小于2mm；为了只将母槽中的锡氧化层刮去，节省耗费锡量，节约工厂成本，其材料优选为钛合金或陶瓷中的任意一种，其材料优选为钛合金或陶瓷中的任意一种，浮动刮锡刀261通过滑杆263连接于气缸262上，气缸262通过底座264固定于支架210上。底座264调整高度使浮动刮锡刀261与子锡炉252上升的最大高度处于一个平面上，当线包浸锡时，顶升装置提升子锡炉252竖直向上运动，抬升至母锡炉251中液态锡液面以上，此时，气缸262带动浮动刮锡刀261往复一次刮锡，从而刮除浸锡槽2522中液态锡表面凝固的锡，从而保证线包在浸锡过程中的顺畅。同时，为回收浮动刮锡刀261刮除的锡，在与浮动刮锡刀261同侧母锡炉251上固定安装一锡渣盒265（为了便于操作者清理锡渣，锡渣盒可以设置为可拆卸型，比如，通过卡扣结构直接扣接在母锡炉上）。
如图13所示为本发明另一个实施例所述子母锡炉和刮锡装置的侧视图，每个顶升装置都包括电机253、轴承座256、丝杆258、丝杆副257及举升臂255，在固定架254的上下两端分别固定两个轴承座256，丝杆258套入轴承座256中，丝杆258的一端与电机253的转动轴连接，且电机固定于固定架254下方，同时，为将丝杆258的轴向转动转化为线性移动，在丝杆258上配合安装丝杆副257，在丝杆副257上固定举升臂255，举升臂255与底板2521连接，从而实现了电机253带动子锡炉252在竖直方向上运动的目的。为保证子母锡炉在使用中始终处于水平状态，在母锡炉251底面安装水平调节机构，其包括固定安装于母锡炉251下底面矩形四个顶点上的调节螺丝259，调节螺丝259两端分别固定于支架和母锡炉251底面上。在设备使用之前，可通过四个调节螺丝259调节母锡炉251相对于水平面的平面度，保证其处于水平状态，从而防止内部锡液由于倾斜溢出子母锡炉。
在本实施例中，第一滑动机构和第二滑动机构的结构和各部件连接关系与上一实施例相同。
如图14所示为本发明另一个实施例所述转动机构的立体图，在第二滑动架232上安装第三电机243，在第三电机243的转动轴上连接有同步轮2451，同时，在第二滑动架232上固定有一框形支架242，在框形支架242上轴向连接取放机构247，取放机构247的一端连接有同步轮2452，在同步轮2451和同步轮2452之间用同步带246连接。在第三电机243启动时，通过同步轮、带，带动取放机构247轴向转动。取放机构247包括轴座、拾取抓头，所述轴座上安装有球头销，球头销上安装有弹簧，拾取抓头安装于弹簧上。
如图15所示为本发明另一个实施例所述取放机构夹取线包的立体图，取放机构247通过挤入线包290的内腔从而拾取线包290。线包290在不同平面上具有多个针脚，本设备同时只能对一个平面上的针脚进行浸锡作业，当完成一个平面针脚的浸锡时，转动机构带动取放机构247转动一个角度，从而将另一个平面的针脚浸入液态锡中，最终实现两个平面针脚都完成浸锡。本发明在沿第一滑轨221的方向设置两个锡炉，其目的为：在完成线包290第一个平面上所有针脚的浸锡后，需要用刮锡装置刮除浸锡槽2522表面凝固的锡，同时将取放机构247转动一个角度对线包290的另一个面上的针脚浸锡；但是，这样并不能保证连续的浸锡作业，极大影响了设备的工作效率。在设置两个锡炉，并且每个锡炉一侧都具有刮锡装置后，在线包290的一个面进行浸锡的同时，另一个锡炉同时进行刮锡操作，当刮锡完成后，线包290的一个面上的所有针脚已完成浸锡，此时，将取放机构247移至已完成刮锡的锡炉中并转动角度对另一个面上的针脚进行浸锡。两个锡炉的设置极大的缩短了线包290的整体浸锡时间，提高了设备的运行效率。
以上对本发明的较佳实施方式进行了具体说明，但本发明并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
