Abstract

一种热风枪头，包括一外壳，外壳的一端设有两列连通外壳的内部的出风口，外壳内的热风可自每一出风口吹出。该热风枪头设有两列出风口，这些出风口可分别对正芯片的各个引脚，使这些引脚的焊锡同时熔化，有利于拆下芯片。

Description

热风枪头
技术领域
本发明涉及一种热风枪头。
背景技术
现有热风枪的头部通常是仅设有一个出风口，从电路板上拆下芯片时，热风枪轮流对芯片的两侧的引脚的焊锡吹热风使其熔化，从而方便取下芯片。然而，芯片的不同引脚受热并不均匀，有的引脚的焊锡刚熔化，先前熔化的焊锡已趋于凝固，不方便进行芯片的拆焊作业。
发明内容
鉴于以上内容，有必要提供一种可方便拆卸芯片的热风枪头。
一种热风枪头，包括一外壳，外壳的一端设有两列连通外壳的内部的出风口，外壳内的热风可自每一出风口吹出。
该热风枪头设有两列出风口，这些出风口可分别对正芯片的各个引脚，使这些引脚的焊锡同时熔化，有利于拆下芯片。
附图说明
下面参照附图结合具体实施方式对本发明作进一步的描述。
图1是本发明热风枪头的较佳实施方式及一芯片的立体图。
图2是图1中的热风枪头的外壳的立体剖视图。
图3是图1中的热风枪头的立体剖视图。
主要元件符号说明
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参照图1和图3，本发明热风枪头的较佳实施方式用于将焊接于电路板的芯片100拆下。芯片100包括一本体101及设于本体101的两侧的若干引脚102。热风枪头包括一外壳10、一传动机构20及一动作机构30。
外壳10包括一内空的头部11及设置在头部11的后端的一圆筒形的颈部16。头部11的前侧面112的中部设有一凹槽12。凹槽12的两端贯穿头部11。凹槽12的两端各设有一连通头部11的内部的开口122（见图2）。头部11于凹槽12的两端分别转动安装一夹块13。凹槽12的两端各设有一连接凹槽12的两相对的侧壁123的枢转杆125。该两枢转杆125分别穿设于该两夹块13，使该两夹块13转动连接于该两枢转杆125。每一夹块13的内侧于远离凹槽12的底壁126处突设一挡片131。每一夹块13的外侧突设一限位部132。头部11的前侧面112于凹槽12的两侧各设有若干排成一列的连通头部11的内部的出风口15。该两列出风口15之间自左向右一一对正。颈部16的外侧设有一垂直于头部11的前侧面112的连通颈部16的内部的滑槽18。
传动机构20包括位于颈部16内的垂直于头部11的前侧面112的两侧均设有若干卡齿211的一推动杆21、位于推动杆21的两侧的与卡齿211相啮合的两齿轮22及一操作杆23。每一齿轮22的中心装设一连接颈部16的内壁162的轴222。操作杆23自推动杆21延伸而出且可滑动地穿设于滑槽18。操作杆23设有一抵接颈部16的内壁162且遮盖滑槽18的挡风部232。
动作机构30包括一大致呈U形的连接部301及两呈向前凸出的弧形的弹片33。连接部301包括连接推动杆21的前端的一连接片31及自连接片31的两侧向前延伸的两延伸片32。该两弹片33分别自该两延伸片32的前端向外延伸出。该两弹片33分别穿过该两开口122后连接该两夹块13的内侧的后端。每一延伸片32的外侧与对应的弹片33的连接处设有一压柱35。
使用时，将热风枪头的这些出风口15分别对正这些引脚102。开启该热风枪头对应的热风枪，热风在流经颈部16及头部11后自这些出风口15吹出。这些出风口15吹出的热风同时吹向这些引脚102，使这些引脚102的焊锡同时熔化。关闭热风枪，向前拨动操作杆23，使推动杆21前移，该两齿轮22转动。该连接部301前移，该两弹片33变形并拉动该两夹块13的后端，使该两夹块13相对张开。将芯片100的本体101收容于凹槽12并位于该两夹块13之间。向后拉动操作杆23，该两弹片33弹性回复，连接部301及推动杆21复位。该两夹块13收合并夹住芯片100的本体101，从而可将芯片100自电路板取走，该两挡片131可防止芯片100向前滑出。每一夹块13向外转动至对应的限位部132抵接头部11的外侧面时无法继续向外转动，进而避免该两弹片33因变形过大而丧失弹性。
在本实施方式中，该两齿轮22使得推动杆21较为平稳地移动。在其他实施方式中，该两齿轮22可以省略，推动杆21可不设卡齿211。
