在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，在不冲突的情况下本申请中的实施例及实施例中的特征可以相互组合。
请一并参阅图1至图4，图1是本发明截止阀一实施例的组合结构示意图；图2是图1所示截止阀的拆解结构示意图；图3是图2所示截止阀中阀体的正视结构示意图；图4是图3所示阀体示沿Ⅳ-Ⅳ线的剖视图。如图1至图4所示，该截止阀1包括设有阀体11和阀芯13，阀体11上设有阀腔以及贯通阀腔的入口、出口和阀芯装配孔，阀芯13可活动密封设于阀芯装配孔内，以用于控制截止阀1的导通和闭合。
在本实施例中，阀腔包括第一输料通道121、第二输料通道122和混合输料通道123，各输送通道具有入口和出口，其中，第一输料通道121的入口和第二输料通道122的入口作本实施例截止阀1阀腔的入口，而两者的出口连通混合输料通道123的入口，以使物料传输过程中第一输料通道121和第二输料通道122所传输的物料汇流入混合输料通道123，再通过混合输料通道123的出口排出，混合输料通道123的出口则作为本实施例截止阀1阀腔的出口。阀体11上设有连通第一输料通道121的第一阀芯装配孔125和连通第二输料通道122的第二阀芯装配孔126，第一阀芯装配孔125和第二阀芯装配孔126上均装配阀芯13，阀芯13可活动密封插设于各阀芯装配孔中，可通过控制阀芯13沿阀芯装配孔伸缩运动以堵塞或打开对应的输料通道，实现其导通和闭合。
在本实施例中，通过控制阀芯13沿阀芯装配孔伸缩运动（即沿阀芯轴向伸缩运动）以堵塞或打开对应的输料通道，实现输料通道的导通和闭合。在其他实施例中，还可将阀芯13设计为其他类型的结构。比如，可以将阀芯设计为包括导通部和阻挡部，阀芯可旋转密封插设于阀芯装配孔中。在工作过程中，当需要闭合截止阀时，旋转阀芯使阻挡部堵塞阀腔中的输料通道，以实现截止阀的闭合；当需要导通截止阀时，则旋转阀芯使输料通道通过阀芯的导通部导通，从而实现截止阀的导通。另外，也可根据实际需要设计阀腔中输料通道和混合输料通道的个数。例如，阀腔仅含一个输料通道；或者阀腔包括一个混合输料通道和与其连通的三个输料通道等。
在本实施例中，截止阀1还包括第一定位结构14，用于阀芯13的轴向调节定位，以实现快速、准确地调节控制截止阀1的导通和闭合。具体地，阀芯13上设有轴向定位凹槽141，轴向定位凹槽141上沿阀芯13的轴向具有两个相对的定位面，包括导通定位面A和闭合定位面B；阀体11上设有第一定位件142，第一定位件142与轴向定位凹槽141配合设置，构成第一定位结构14，用于调节阀芯13控制输料通道的导通和闭合时阀芯13的调节定位。例如：若要闭合输料通道，压缩阀芯13，阀芯13沿阀芯装配孔运动，当轴向定位凹槽141的闭合定位面B抵接到阀体11上的第一定位件142时，可实现对输料通道的堵塞、闭合；若要导通输料通道，则拉伸阀芯13，阀芯13沿原路径返回，当轴向定位凹槽141上的导通定位面A抵接到阀体上的第一定位件142时，则可实现对输料通道的打开、导通。从而通过以上第一定位结构14的设置，可快速、准确地实现调节截止阀1的导通和闭合，操作方便，提高工作效率。
此外，第一定位结构14也可设置为其他的结构，以用于实现阀芯的准确调节定位。例如，可将定位凹槽设置在阀腔上，相应地将第一定位件设置在阀芯上，配合构成第一定位结构；或者将第一定位结构设置为在阀芯上的导通定位标识和闭合定位标识，在阀芯伸缩过程中，通过导通定位标识和闭合定位标识进行定位判断。
为了提高截止阀的稳定性，本实施例截止阀1还包括限位结构15，用于阀芯13的限位固定。该限位结构15具体为平齐于阀芯13上轴向定位凹槽141的闭合定位面B且连通轴向定位凹槽141的限位卡槽，限位卡槽与第一定位件142配合设置，用于调节阀芯13堵塞输料通道后阀芯13的限位固定。具体地，在使用时，当调节阀芯13堵塞输料通道后，旋转阀芯13，使第一定位件142卡接固定于限位卡槽内，以实现对阀芯13的限位固定，避免阀芯13松动，输料通道导通。
在其他实施例中，限位卡槽也可设为平齐于定位凹槽的导通定位面A且连通定位凹槽，用于调节阀芯导通输料通道后阀芯的限位固定。或者定位凹槽两端均可设置限位卡槽，通过与第一定位件配合，分别用于截止阀导通和闭合状态下阀芯的限位固定。
此外，限位结构15还可采用其他结构。如限位结构包括设于阀芯上的限位卡槽和与阀体固定连接的弹性卡接件；弹性卡接件包括安装部和活动卡接部，其中，安装部与阀体固定连接，且与活动卡接部可恢复转动连接，活动卡接部可与限位卡槽配合卡接以限位固定阀芯，用于截止阀导通和闭合状态下阀芯的限位固定。
为了便于实现第一定位结构14的准确配合，本实施例截止阀还包括第二定位结构16，用于第一定位结构14中轴向定位凹槽141和第一定位件142的配合定位。该第二定位结构16包括设于阀体11上的第二定位件161以及设于阀芯13上的抵接定位件162，第二定位件161和抵接定位件162配合，用于阀芯13在旋转过程中通过第二定位件161和抵接定位件162的抵接使第一定位件142定位于轴向定位凹槽141内，实现第一定位结构14快速、准确地定位。当然，第二定位结构16也可采用其他结构形式，如直接在阀芯和阀体上配合设置定位标识，当阀芯上定位标识与阀体上定位标识对准时，第一定位结构准确定位。
以上截止阀可应用于输料管路或包括输料管路的设备装置，以灵活控制管路的导通和闭合，从而便于在生产过程中更换管路和部件时，停止物料输送，避免更换管路或部件造成输送物料的泄露，导致污染环境和破坏环境卫生。
本发明还提供一种点胶装置，具体请参阅图5和图6，图5是本发明点胶装置一实施例的结构示意图，图6是图5所示点胶装置中M处的局部放大结构示意图。如图5和图6所示，该点胶装置包括四个彼此独立的点胶单元，点胶单元包括供胶机构2、多轴机械手3、点胶针头4和图1所示实施例的截止阀1。其中，供胶机构2连接截止阀1上阀腔的入口，点胶针头4连接截止阀1上阀腔的出口，多轴机械手3与点胶针头4连接，以通过多轴机械手3控制点胶针头4进行点胶。
供胶机构2包括胶桶21、第一驱动装置22和输胶管23。其中，胶桶21用于装盛胶料，胶桶21通过输胶管23与截止阀1连通；第一驱动装置22用于推动胶桶21内胶料以供料。参阅图1和图5，在本实施例中各点胶单元的供胶机构2包括两个胶桶21，且分别通过输胶管23连通截止阀1上的第一输料通道121的入口和第二输料通道122的入口；第一输料通道121和第二输料通道122连通管混合输料通道123，点胶针头4连通混合输料通道123的出口。且在本实施例中，多轴机械手3具体为三轴机械手，截止阀1与多轴机械手3可拆卸、可调节固定连接。
在使用时，两个胶桶21可用于装盛两种不同的胶料，而后在第一驱动装置22的驱动下，胶桶21内物料分别通过输胶管23流入截止阀1上的第一输料通道121和第二输料通道122，在截止阀1导通状态下，胶料汇流入截止阀1上的混合输料通道123，进而流入点胶针头4，通过多轴机械手3控制点胶针头4进行点胶。当需要更换点胶针头或其他情况下，需要停止输料时，可通过控制截止阀1闭合，以停止输料，从而可操作的灵活性及避免胶料的泄露。
在本实施例中，供胶机构2包括两个胶桶21，多轴机械手3为三轴机械手。在其他实施例中，可根据实际胶料的种类等实际情况，选用单个或其他多个（如2个、5个、6个、8个等）胶桶或盛胶容器，并与相应的截止阀配合；此外，也可采用其他多轴机械手，如两轴机械手。而点胶单元的个数也可根据实际需要设置，可设为1个、2个、5个、8个等。
如图6所示，为了提高点胶装置的灵活性，点胶单元还可包括点胶控制机构5，该点胶控制机构5包括第二驱动装置51和阻胶部52，点胶针头4上设有与阻胶部52相配的套孔，该套孔连通管点胶针头4内的输胶孔；阻胶部52与套孔可伸缩连接，第二驱动装置51用于驱动阻胶部52沿套孔往复运动以堵塞或打开输胶孔，从而在点胶过程中灵活控制点胶。具体地，在需要点胶时，通过第二驱动装置51提升阻胶部52，输胶孔打开，进而可进行点胶操作；当需要停止点胶时，通过第二驱动装置51推动阻胶部52堵塞输胶孔，以实现停止点胶。
为了便于部件的更换，多轴机械手3通过拆卸固定件6与点胶针头4可拆卸固定连接，以便于灵活拆取点胶针头4。此外，多轴机械手上还固定设有针头定位部7，以用于固定点胶针头4上的针头，避免其偏动，影响点胶。本实施例点胶装置还包括用于控制各驱动装置的电磁阀8，且点胶装置可通过支架整体统一支撑设置。
尽管结合优选实施方案具体展示和介绍了本发明，但所属领域的技术人员应该明白，在不脱离所述权利要求书所限定的本发明的精神和范围内，在形式上和细节上可以对本发明做出各种变化，均为本发明的保护范围。
