Description

一种传输对位装置以及一种对接设备 技术领域
本发明涉及电子产品自动化生产技术领域，具体涉及一种传输对位装置以及一种对接设备。
背景技术
随着电子技术的快速发展，印制电路板广泛应用于各个领域，印制电路板又称PCB(Printed Circuit Board)，PCB板是现代电子行业中的必备元件，其用于电子元器件电气连接，是电子元器件的支撑载体。为保证电子设备正常工作，减少相互间的电磁干扰，加工制造后的印制电路板要进行质量检测，以检测印制电路板的性能是否符合要求。随着科学技术的发展，市场上出现了PCB板的生产和质量检测设备，利用设备能够实现对PCB板的自动生产和检测，一定程度上降低了操作员的人力劳动强度。
但在现有设备的生产作业中，通常PCB板的质量检测是采用独立设置的检测设备分别进行的，而PCB板通常需要经过多种检测设备执行多道检测程序，在转换设备或者转换工艺流程时，一方面，仍有相当一部分工作需要操作人员人工对PCB板进行放置和移送，自动化程度低，从而导致工作效率低，生产线的产能低，无法满足流水线批量检测需求，耗费人工成本同时容易造成被检测PCB板产生二次污染等问题。
另一方面，人工上料以及传输过程中必然会存在PCB板在水平面内的角度偏移，因此在传输过程中，若不及时进行纠正易增加PCB板传输和生产过程中的损坏率，现有技术中通常通过推板从板体相对的两侧同时对PCB板施加夹紧操作，纠正位于传送辊上的PCB板的位置，但上述夹紧操作通常会带来PCB板在传送辊上的水平移动，易刮伤板体表面，且若夹紧操作不当易加大对PCB板的损坏。
发明内容
因此，本发明要解决的技术问题在于克服现有技术中的PCB板产线布置方式不灵活以及自动化程度低从而导致的生产效率低、产能低的缺陷，从而提供一种可灵活设置于装置之间的、以提高自动化程度的对接设备。

实施例1
如图1-2所示，本发明记载了一种对接设备，该对接设备包括：输入平台1、输出平台2和搬运机构3，其中输入平台1接受上游装置的输出物料，输出平台2的出料端21对下游装置输出物料；搬运机构3将物料从输入平台1搬运至输出平台2，其中在输入平台1和/或输出平台2上设有传输对位装置。本实施例中的物料指电路板10，当然其也可为其他板状物料或者具有平面的非板状物料。
其中输入平台1设置有至少两个，输出平台2的物料输出方向不同于输入平台1的物料输入方向，且输入平台1的入料端11和输出平台2的出料端21对接于不同的装置。
本实施例中设有两个输入平台1，两个输入平台1分别相对的设于输出平台2的相对两侧，且输出平台2的物料输出方向与输入平台1的物料输入方向垂直，如图1所示，输入平台1的物料输入方向为沿对接设备长度方向(即图1中所示上下方向)，输出平台2的物料输出方向为沿对接设备宽度方向(即图1中所示左右方向)。同时，如图1所示，本实施例中的两个输入平台1的入料端11分别对接于上游的两个开短路检测装置91，输出平台2的出料端21对接于下游的外观检测装置92(本实施例中的上游至下游方向指产线上物料的传输方向)。通过搬运机构3将输入平台1上的电路板10 抓取放置于输出平台2上以对下游的外观检测装置92输出。通过本实施例的对接设备可将两台开短路检测装置91和一台外观检测装置92集成自动连线检测，有利于检测效率的匹配，大大提升检测效率，减少人工成本，降低人对产品的接触而造成对产品的二次污染，提高产品质量和合格率；同时实现自动传输、自动测试，达到自动化检测的目的，避免产线的中断，降低人力消耗。
如图2-3所示，将输入平台1上的物料搬运至输出平台2上的搬运机构3，其包括直线模组31和抓取组件32，参照附图3，本实施例的直线模组31沿水平方向依次横跨经过位于输出平台2一侧的输入平台、位于中间的输出平台2和位于输出平台2另一侧的另一输入平台1。本实施例中的直线模组31包括传动丝杆、导轨和模组电机311，抓取组件32通过升降单元连接于传动丝杆，传动丝杆由位于其端部的模组电机311驱动正反转从而带动其上的抓取组件32沿传动丝杆做直线往复运动。抓取组件32通过升降单元可相对于输出平台2进行竖直升降，抓取组件32朝向输出平台2的端部设置有若干吸盘321，吸盘321连接于负压源，通过升降运动执行吸取和放置电路板10的操作，通过直线模组31在输入平台1和输出平台2之间运动实现电路板10的搬运，本实施例中抓取组件32分别将位于两侧的输入平台1上的电路板10吸取移动到中间的输出平台2上方，然后抓取组件32通过升降单元下降，当抓取组件32接收到设于输出平台2上方的传感器的放板信号后，将电路板放置于输出平台2的传送辊41上。
其中开短路检测装置91用于测试电路板上是否存在短路(指PCB板上不应该连接的地方连接)和断路(指PCB板上应该连接的地方没有连接)；外观检测装置92用于检测电路板表面的字符和符号的丝印是否清楚，明显，颜色符合规定，是否有重复印刷，漏印刷，多印刷，位置偏位，错印等缺陷；以及电路板表面是否有污渍、杂物、凹坑、锡渣残留；板面是否划伤露底材；边缘是否有洗边后留下的毛刺、缺口；多层板是否会有分层、等缺陷。开短路检测装置和外观检测装置均属于本领域的常规检测仪器，在此不对其内部结构做赘述。
如图1所示，位于上游的开短路检测装置91具有开短路检测合格出料端911和开短路检测不合格区912，其中开短路检测不合格区912用于放置经开短路检测装置91检测不合格的电路板，开短路检测合格出料端911向位于其下游的对接设备8输出开短路检测合格的电路板。同时，外观检测装置92也具有外观检测合格出料端921和外观检测不合格区922；外观检测合格出料端921输出开短路和外观检测均合格的电路板，外观检测不合格区922输出开短路检测合格而外观检测不合格的电路板。
参见附图4-8，本实施例的输出平台2上设有传输对位装置。通过输出平台2上的传输对位装置可将电路板10自动靠边移动至预定位置，并沿直线向输出平台2的出料端21移动，最终将电路板10准确输送至外观检测装置92的入料口，实现了电路板10由开短路检测装置91准确输送到外观检测装置92中的目的。
其中传输对位装置包括传输机构4和升降对位机构5。通过设置有升降对位机构对传送物料执行自动对位，有利于物料的规律传送，避免在传送和取放料过程中产生物料的破损，提高生产效率和合格率，降低成本，可自动执行对位操作，不需要人工操作；且由于设置有升降对位机构执行自动对位，对搬运机构3的操作精度要求降低，简化了搬运机构3的控制要求和结构设计，降低了人力和设计成本。
传输机构4具有对物料进行支撑传送的传送面(传送面是指传送物料时传输机构与物料的接触部分所在平面，由于电路板为平板部件，因此本实施例中的传送面即电路板下表面所在平面)；其中升降对位机构5顶升至接触物料时启动对位操作，升降对位机构5下降至脱离物料时停止对位操作，通过上述升降和对位操作将物料传递至传送面上并使其沿传送面上的预定位置传送。其中对位操作的对位方向不平行于传输机构4的传送方向。
如图4-6，本实施例中传输机构4包括若干组传送辊41，各组传送辊41分别通过辊轮轴42安装于传输机架43上。传输机架43固定于输出单元2的机架上端；各个辊轮轴42平行且互相间隔设置，相邻的两个辊轮轴42之间设有第一间隔45。如附图9所示，传输机构4还包括驱动各辊轮轴42转动的辊轮电机44和传动组件，其中辊轮电机44通过设置于一侧传输机架43内的传动组件与各个辊轮轴42连接，通过辊轮电机44同时驱动所有的辊轮轴42同步转动从而带动连接于辊轮轴42上的传送辊41向同一方向同步转动，由此实现对放置于传送辊41上的物料的匀速传输。其中传动组件可为同步带或齿轮传动件或链传动件中的任意一种或几种。
本实施例中升降对位机构5固定设置于传送面的下侧向传送面上侧顶升电路板10使其脱离传送面，并驱动电路板10沿与传输机构4的传送方向垂直的对位方向水平移动到预定位置。其中预定位置指贴近传输机架43一侧边的位置，本实施例中指图2-3中输出平台2的右侧边的位置，经过升降对位机构的对位操作电路板10贴近输出平台2的右侧依次输出。
如图4、7-8所示，本实施例的升降对位机构5包括对位单元6和升降单元7，对位单元6将电路板10移动至预定位置；升降单元7驱动对位单元6升降。首先通过升降单元7将电路板顶升脱离传送面以允许电路板10进行对位移动，其次，升降单元将电路板下降至传送面上以实现后续传送，通过设置升降单元7可快速实现传送和对位 的切换，通过设置对位单元可实现电路板的对位操作。其中如图4、7、8所示，对位单元6包括至少一组移动组件和基座61，移动组件设于基座61上，升降单元7驱动基座61升降。
本实施例中的移动组件包括驱动电机62和由电机驱动的若干传送带63，其中传送带63的运动方向平行于传送辊或辊轮轴的轴线。本实施例中传送带63的运输方向与传送辊41或辊轮轴的轴向垂直；即移动组件的对位方向与传输机构的传送方向垂直，参见附图6，本实施例中的传送方向指图6中由左向右的方向，对位方向指图6中由下向上的方向。当然作为可替换的实施方式，如图2-3所示由于该对接设备的上下两侧均可以对接下游输出装置，即图6中左右两侧均可对接下游的输出装置，因此当下游输出装置设置于图3中上侧即图6中左侧时，也可改变传送辊41的传输方向，设置传送方向为图6中由右向左的方向，对位方向仍为由下向上的方向。
通过设置转动的传送带驱动电路板执行对位操作，避免电路板与传送辊之间发生位移，由此避免因上述位移导致的电路板的表面损伤，提高了生产合格率。另外通过设置与传送辊的辊轮轴平行的传送带，并允许传送带插入相邻的传送辊之间以允许移动组件与传输机构在升降和对位操作中互不干涉，同时将物料传送至传输机构的一侧实现对位。
其中传输机构4的若干组传送辊42互相平行设置，对位单元6的传送带63也互相平行设置，传送带63由顶升单元驱动可插入相邻两组传送辊41之间且与两侧的传送辊41互不发生干涉。相邻的两传送辊42之间设有允许传送带63进入的第一间隔45；相邻的两传送带63之间设有允许传送辊42进入的第二间隔64；传送带在升降过程中不与相邻两侧的传送辊41发生干涉。
参见附图7-8、10-11，升降单元7包括安装座71以及安装于安装座71上的升降气缸72和若干导向单元73，其中安装座71固定于输出单元的机架上，升降气缸71的缸体固定安装于安装座71，其活塞杆74连接于基座61，本实施例中在基座61和安装座71之间还设有若干平行设置的导向单元73用于引导升降气缸72执行平稳升降运动。本实施例中的导向单元73为直线轴承；基座61由升降气缸71驱动带动位于基座61上的移动组件进行升降运动。
本实施例中，传输机构4上与预定位置对应处还设有对物料限位的纠偏挡板431，纠偏挡板431沿平行于传输机构4的传送方向设置，即纠偏挡板431沿垂直于辊轮轴42的方向设置。其中在传输机构4的传输机架43的预定位置侧固定有纠偏挡板431，本实施例中纠偏挡板设置在辊轮轴42的轴向端部，纠偏挡板431用于对电路板10的 位置进行校正，纠正其在水平面内发生的旋转或者偏移，使其贴近纠偏挡板并保持中正的位置进入下游装置。
本实施例中在纠偏挡板431与电路板对应位置处还设置有传感器(未在图中示出)，通过传送带旋转带动电路板运动置纠偏挡板431的一侧，该传感器检测到电路板后，向控制器发送指令驱动升降单元执行下降动作，对位单元的传送带63会下降到低于传送辊上输送物料的传送面的高度，电路板10下落至传送辊上，电路板10通过传送辊41的驱动，沿着纠偏挡板431进行前移，实现电路板10准确输送至外观检测装置92入料端的功能。
本发明由于设置有纠偏挡板431，通过设置纠偏挡板对物料进行纠偏校正，纠正物料在传输过程中发生的位置转动和角度偏移，能够对电路板的位置进行重新校正，因此对电路板的原始上料位置要求降低，且进一步避免在传送和取放料过程中产生物料的破损，提高生产效率和合格率。
如图2-3所示，本实施例中的输入平台1设有升降台12，其中升降台12在上游装置的出料端和输出平台2的入料端之间升降。本实施例中输入平台1包括由其外壁围合而成的升降空间，其中在升降空间内设置有可升降的升降台12，升降台12在位于底端时与上游的开短路检测装置91的开短路检测合格出料端911对接，用于接收由开短路检测合格出料端911输出的若干堆叠的电路板；升降台12上升后，其顶部的电路板10与输出平台2对接。
为便于准确控制升降台12的运动，输入平台1的内侧下部还设有有板传感器，当其检测到升降台12上输入有电路板10时向控制器发出启动运行的信号，控制升降台12上升；输入平台1内上部还设有对升降台12顶部的电路板10进行检测的上限位传感器，当其检测到顶部电路板到达指定位置时向控制器发出停止运行信号，升降台12停止上升。该上限位传感器用于限制上升平台的上升位置，限制其过度上升，确保位于升降台12上的电路板10处于抓取组件可抓取的范围内。其中本实施例中的有板传感器和上限位传感器均采用位置传感器。
本实施例中的升降台12通过丝杆和升降电机驱动升降，具体地，升降台12通过例如丝杆滑块或丝杆螺母等连接件连接于传动丝杆，传动丝杆的端部设有升降电机，升降电机受控制器控制运转。
本实施例中的传送辊41为包胶轮结构，其外层采用聚丙烯(PP)或者聚偏氟乙烯(PVDF)或者聚氨酯材料制成，由此避免对电路板表面造成损伤。
本实施例中的对接设备8还设有可供操作人员进行操作的操作端口81，操作端口81可设置包括与控制器连接的例如显示器、键盘或者触控显示屏等装置，便于操作人员对对接设备直接进行操作。
作为可替换的实施方式，移动组件也可设置为包括驱动件和由其驱动的若干组滚轮，各组滚轮的轴线与传送辊的轴线垂直；且各组传送辊平行设置，各组滚轮由顶升单元驱动可插入相邻两组传送辊之间且互不干涉。具体地，相邻的传送辊之间设有允许滚轮进入的第一间隔；相邻的滚轮之间设有允许传送辊进入的第二间隔；滚轮在升降过程中不与相邻两侧的传送辊发生干涉。当然，当传动组件包括滚轮时，滚轮同样也可采用聚丙烯或者聚偏氟乙烯或者聚氨酯材料制成，由此避免对电路板表面造成的损伤。
在可替换实施方式中，传输机构4还包括设于其输出端的传送带，参见附图6中左侧的传送带，当然其也可在图6中右侧同样设置有传送带；此时传送带具有与传送辊41持平的传送面，且纠偏挡板431延伸至传送带所在区域。
作为可替换的实施方式，对接设备的输入平台1也不限于只设两个，也可在输出平台2上未设有出料端21的另外三侧分别设置有三个输入平台1。当输出平台2的三侧分别设置有输入平台1时，此时的搬运机构可采用机械手或者仍可设置包括模组和抓取组件，此时模组包括位于水平面内的X轴模组和Y轴模组，且X轴模组与Y轴模组垂直，X轴模组可在Y轴模组上滑动运动，X轴模组上连接有抓取组件用于抓取运输电路板。
当然，作为可替换的实施方式，输入平台也可设置为传送辊传送的方式，当其设置有传送辊时，输入平台上也可设有传输对位装置。
当然作为可替换的实施方式，不同的输入平台可对接不同的装置，例如两个或三个输入平台分别对接不同的检测装置。
本发明的对接设备的工作过程如下：
a：开短路检测及出料过程：
将电路板放入开短路检测装置的人工上料区913，开短路检测装置91对电路板执行开短路检测，并将不合格的电路板输出至开短路检测不合格区912；同时将检测合格的电路板输出至开短路检测合格出料端911；
b:输入平台上料过程：
当开短路检测合格出料端911的电路板堆叠达到预定数量后经其出料端的运输装置例如传送带等将堆叠的电路板传送至对接设备的升降台12内；
输入平台1内的有板检测传感器检测到升降台12上输入电路板后向控制器发送启动指令，升降电机启动驱动丝杆旋转由此带动升降平台12上升，当位于输入平台1上部的上限位传感器接收到检测信号时向控制器发送停止指令控制升降电机停止旋转，升降台12停止上升；需要说明的是，若此时多个开短路检测装置共同作业，则与其对接的多个输入平台12分别执行上述上料过程；
c：搬运过程：
当升降台12上升至预定位置后，控制器控制搬运机构启动抓取组件，通过吸盘吸取位于升降台12顶端的电路板，并通过直线模组将其运输至输出平台2上，向位于输出平台2下游的外观检测装置92输入电路板10；其中在此过程中经由输出平台2转变了电路板10的传送方向，即输出平台的物料输出方向与输入平台的物料输入方向不同；
在此过程中，当升降台12内的电路板10减少至上限位传感器无法检测时，控制器发送指令驱动升降电机启动，从而驱动升降台12上升使其顶部的电路板始终处于抓取机构取料的预定范围内。
d：输出平台的自动对位过程：
搬运机构将电路板10放置于传送辊41上并触发传输机构上的检测传感器，检测传感器检测到传送辊41上存在电路板后控制器控制升降单元上升，升降气缸72驱动基座61上升，从而带动位于其上的传送带63插入传送辊41之间的第一间隔45中，并驱动位于传送辊41上的电路板10脱离传送面；同时电路板10经由传送带63传送至位于传送辊轴向一侧的预定位置(本实施例中指图3中输出平台的右侧位置)，并与纠偏挡板431相抵接，此时经过传送带63与纠偏挡板431的共同作用，电路板10的一侧边完全抵接至纠偏挡板431，纠正了因抓取组件抓取过程中产生的角度偏移，此后当设置于纠偏挡板431上的传感器检测到电路板10后，控制器控制升降气缸72下降，电路板10经由传送辊41传送至下游的外观检测装置92。
e：外观检测及出料过程：
经由输出平台2输出的电路板进入外观检测装置92执行外观检测，经检测外观合格的电路板输出至外观检测合格出料端921，外观检测不合格的电路板则输出至外观检测不合格区922。
本发明通过设置有对接设备可用于不同装置之间的衔接和过度，可根据产线需求灵活布置，包括输入平台的种类、数量和位置，以及输出平台的种类均可灵活选择。由于同时设置有多个输入平台和输出平台分别对接上游装置和下游装置，无需人工搬运和调整，有利于提高产线的自动化程度，提高产线效率。
本发明通过设置有对接设备，经过开断路检测装置检测后，合格产品和不合格产品自动进行分离，合格产品将自动输送到对接设备并经输出单元准确输送至外观检测装置，经过外观检测装置检测完成后，合格品和不合格品自动识别分离，不合格产品和合格产品通过人工进行下料，最终完成对电路板的开断路检测和外观检测。本发明的开断路检测装置和外观检查装置在控制部分设置成可独立工作，即：在本自动检测产线中任何一个独立设备发生故障需要检修时，其他设备均可独立工作，使得设备运用更加灵活，设备运行效率更高。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
