Description

一种管路的焊接装置 技术领域
本发明涉及管路焊接技术领域，特别是涉及一种管路的焊接装置。
背景技术
家用冰箱的制冷方式主要是依靠系统管路的放热和吸热达到冰箱空间降温的目的。为了便于冰箱批量生产，系统管路需分段安装后再进行管路连接。管路连接处需要进行钎焊，依靠高温火焰枪加热管路连接处，焊接时加入焊料融化成熔融态以填充管路连接处的缝隙，使管路形成密封，这样能保证制冷剂在系统管路中循环流动时不会出现泄漏等问题，能使冰箱长期处于稳定工作状态，满足使用需求。
现有的焊接设备为单头和双头火焰枪，在实际使用焊接设备的过程中，经常出现焊接的管路局部集中受热，管路氧化严重的问题，容易发生管路焊漏，造成产品抽空不良等情况，使得冰箱性能不达标，需要批量返修。还有现有焊接设备在实际使用过程中，由于管路是批量生产，需要保障产量，若重复点火，则需要浪费很多时间。因此，为了节省生产时间，焊接设备需要保证火焰喷头一直处于燃烧状态，这样则存在资源浪费，例如氧气和天然气/乙炔等。另外，由于冰箱功能趋向多样化，冰箱机舱内的电器件和线束也越来越多，管路焊接点也大部分位于机舱空间，现有焊接设备工作时，火焰长度较长会烧损电器部件及线缆。
综上，目前生产线使用的焊接设备对管路进行焊接时存在以下缺点：
1.对焊接管路加热不均匀，易出现管路焊漏或局部过烧现象，造成产品抽空不良使得冰箱性能不达标，需要批量返修；
2.使用现有焊接设备批量工作时，设备一直保持火焰燃烧，存在资源，具体为氧气、天然气或乙炔等浪费；
3.由于冰箱机舱空间有限，现有焊接设备工作时火焰长度较长经常出现烧损电器部件及线缆。

该实施例通过设置多个间隔开布置的多个火焰喷头11，在对待焊接管路进行焊接时能够使得待焊接管路受热均匀，保证良好的焊接质量，避免出现待焊接管路焊漏，造成产品抽空不良等情况。
在该实施例中，焊接装置100还包括气体通道20和控制阀70，其中，气体通道20与环状管件10连通，用于向环状管件10输送点火气体。控制阀70设置在气体通道20处，用于控制气体通道20的通断。这里的控制阀70为电磁阀。
具体地，气体通道20与燃气管21和氧气管22均相连，用于向环状管件10输送燃气和氧气，其中，燃气可以使用天然气、乙炔等可燃气体。在使用天然气的情况下，燃气管21用于向环状管件10中输送天然气，氧气管22用于向环状管件10中输送氧气。电磁阀能够控制燃气管21和氧气管22进入环状管件10中气体的流量，从而调节火焰喷头11喷火的长度。一般地，进入环状管件10中的氧气和天然气的流量越多，则火焰喷头11喷火的长度越长，进入环境管件中的氧气和天然气的流量越少，则火焰喷头11喷火的长度越短。
在该实施例中，焊接装置100还包括环形挡火片15，环形挡火片15设置在环状管件10的外周。环形挡火片15的横截面呈弧形，从而通过弧形的设计可以避免火焰烧坏其他部件。
在该实施例中，环形挡火片15具有相对的第一端131和第二端141，第一端131和第二端141设置成受控地分离和闭合，环形挡火片15构造成在第一端131和第二端141闭合时为连续的环形，在第一端131和第二端141分离时为具有缺口的环形。其中，第一端131和第二端141设置成在分离时向控制阀70发送分离信号，以使得控制阀70控制气体通道20断开。第一端131和第二端141设置成在闭合时向控制阀70发送闭合信号，以使得控制阀70控制气体通道20导通。多个火焰喷头11限定出的空间呈圆形，有利于管路穿过环状管件10。火焰喷头11的长度可以根据管路的直径进行设定。在环状管件10直径一定的情况下，管路的直径越大，则火焰喷头11的长度越短，管路的直径越小，则火焰喷头11的长度越长。
在该实施例中，火焰喷头11的数量为六个，六个火焰喷头11均匀布置在环状管件10上。优选地，当环形挡火片15的第一端131与第二端141分离时产生的缺口，也就是两者 之间的间距不大于相邻两个火焰喷头11之间的间距。在其他实施例中，火焰喷头11的数量还可以根据具体的设计需求进行设定，例如四个、八个或十个等等。
一般地，火焰喷头11的数量根据环状管件10的直径来决定。环状管件10的直径越大，则火焰喷头11的数量越多，环状管件10的数量越少，则火焰喷头11的数量越少。
具体地，环形挡火片15包括第一部分13和第二部分14，第一部分13具有第一端131和第三端132，第二部分14具有第二端141和第四端142，第三端132和第四端142滑动连接。在第一端131与第二端141闭合时，第三端132和第四端142可以设置成重叠，也可以设置成不重叠。最优选地，第三端132和第四端142在第一端131与第二端141闭合时也处于闭合状态，可以防止火焰喷头11喷出的火从环形挡火片15处喷出，避免烧坏靠近管路的其他部件，也可以保证人员安全，避免人员被烧伤，受到伤害。在环形挡火片15的第一端131与第二端141由闭合状态切换至分离状态的过程中，第四端142沿着第三端132滑动至两者重叠的位置处。
在该实施例中，焊接装置100还包括控制模块60，其与控制阀70连接，用于控制控制阀70的开闭。
在该实施例中，焊接装置100还包括压力传感器，其具有第一感应片和第二感应片，且与控制模块60连接，第一感应片设置在第一端131处，第二感应片设置在第二端141处，控制模块60配置成在第一感应片和第二感应片闭合时控制控制阀70开启，在第一感应片和第二感应片分离时控制控制阀70关闭。
该实施例通过压力感应来实现控制阀70的开闭，以控制火焰喷头11喷火和关火的目的，控制比较方便，且能够达到节约能源的效果。
在该实施例中，焊接装置100还包括活动把手30，活动把手30与第二部分14连接，用于在外力下带动第二部分14的第四端142沿第一部分13的第三端132滑动，使得第一部分13的第一端131与第二部分14的第二端141分离或闭合。
在该实施例中，气体通道20与第一部分13的靠近第三端132处连接。活动把手30与第二部分14的靠近第四端142处连接，且与气体通道20相邻布置。
在该实施例中，焊接装置100还包括弹性件80，其一端与活动把手30连接，另一端与气体通道20连接。当用户打开活动把手30，使得活动把手30带动第二部分14沿着第一部分13滑动，从而使得第一端131与第二端141闭合时弹性件80处于伸长状态。当用户松开活动把手30并压住活动把手30时压缩弹性件80使得弹性件80处于压缩状态，从而带动第二部分14沿第一部分13滑动，以使得第一端131与第二端141分离，从而使得火焰喷头11熄火。这里的弹性件80为压力弹簧。在其他实施例中，弹性件80还可以选择其他具有弹性的部件。
在该实施例中，焊接装置100还包括套筒90，其套设在气体通道20上且与气体通道20固定连接。弹性件80的一端与套筒90连接。另外，焊接装置100还包括开关40，其安装在气体通道20处，用于在外力下开启或关闭，以使得焊接装置100处于通电状态或断电 状态。具体地，开关40是安装在套筒90上的。
在该实施例中，焊接装置100还包括供电线50，其与控制模块60连接，用于在开关40开启时给焊接装置100供电，在开关40关闭时停止给焊接装置100供电。
该实施例中焊接装置100的使用步骤如下：
步骤一：按下开关40，使得焊接装置100处于通电状态；
步骤二：通过控制模块60设定电磁阀的流量，调节火焰喷头11的火焰长度；
步骤三：按动活动把手30，从而压缩弹性件80，使环形挡火片15的第一端131与第二端141分离，从而打开通道，使得待焊接管路进入环状管件10中；
步骤四：在待焊接管路处于火焰喷头11中间位置处时打开活动把手30，使得位于环形挡火片15两端的第一感应片和第二感应片接触，生成感应反馈信号并传递到控制模块60，控制模块60控制电磁阀打开气体通道20，燃气管21中的天然气/乙炔和氧气管22中的氧气混合后按照设定的流量供给环状管件10；延迟5s后控制模块60给出点火指令使点火器12发出点火花，以点燃六个火焰喷头11，使均匀分布的六个火焰喷头11给待焊接管路均匀加热，待工作人员给焊点位置加入合适钎焊料即完成一个管路焊接；
步骤五：管路焊接完成后，再次压动活动把手30，使得位于环形挡火片15两端的第一感应片和第二感应片分离，生成感应反馈信号给到控制模块60，控制模块60控制电磁阀关闭，以切断气体通道20，断气后加热火焰自动熄灭，之后将焊接完成后的管路移出环状管件10；
步骤六：若焊接装置100需要继续工作，则重复步骤一至步骤五的操作；若焊接装置100停止使用，则关闭开关40，松开活动把手30，使得弹性件80复位即可。
该实施例设计了一种管路的焊接装置100，设计了六个沿环状管件10均匀分布的火焰喷头11，在对管路进行焊接时能使管路受热均匀且保证良好的焊接质量。并且通过压力感应来控制焊接装置100点火和关火，达到节约能源的效果。另外通过电磁阀控制氧气和天然气/乙炔等的流量，使得火焰喷头11的火焰长度适中以及处于焊接装置100外圈的环形挡火片15能够减小烧损电器件及线缆的风险。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
