Description

一种上下料机构及具有该机构的测试设备、测试系统 技术领域
本发明涉及生产检测设备技术领域,具体涉及一种上下料机构及具有该机构的测试设备、测试系统。
背景技术
目前,立式飞针测试机在检测印刷电路板(PCB板)时多采用人工送板的方式将待测线路板置于测试机的上下夹具中,在固定时需要操作人员操作测试机上下夹具的操作按钮,来完成夹板和飞针初始定位过程,然后测试完成后再人工将其从检测机上取下,近来市场上出现了相应型号的自动检测设备。
中国专利文献CN107121632A公开了一种飞针测试系统,包括机械手与测试设备,在检测过程中,PCB板由机械手臂夹取并放置于测试设备中的检测工作区内,实现了一定程度的自动化生产,但是整个上下料的过程中,机械手将PCB板夹持进入工作区的路径是面向测试装置从正面送板或取板,需要穿过测试装置,因此为了避免与测试装置产生干涉,通常PCB板的面积不能超过各个测试装置之间的空隙的平面面积,才允许PCB板经过各个测试装置之间的空隙进入工作区,因此,进一步限制了可检测的PCB板的面积,导致现有测试设备可检测的PCB板的面积受限,不能用于实现板面面积较大的PCB板的自动化检测;与此同时,正面送取板的操作方式也限制了测试设备进行成组布局的形式,在工作空间区域有限且要配合机械手臂实现自动化生产的情形下,为有效使用工作空间而使测试设备成组布局是十分必要的。
中国专利文献CN206906539U,公开了一种对多台飞针测试机自动上下料机构及飞针测试生产线,包括:基座、可在所述基座上滑动的机械手移动平台、 固定在所述机械手移动平台上的机械手、置在所述基座一侧的待测板传送机和已测板传送机;所述飞针测试生产线包括:一种对多台飞针测试机自动上下料机构和不少于两台飞针测试机。该专利实现了对多台飞针测试机上下料,但是在上下料过程中也是利用机械手臂面向测试装置将物料放置到飞针测试机内部,同样会发生干涉,且该飞针测试机上包含有能与所述机械手配合使用的自动化夹具;所述自动化夹具可在机械手的配合下自动装夹和自动取下电路板,故而机械手需要待物料由夹具固定之后才能将物料释放,其余未放板的飞针测试机需要等待一定的时间,故而当设置更多的测试设备时,机械手将不能满足测试的产能需求,故而不能够进行成组布局,且该生产线在实际应用到生产中时,占用场地较大,不能够适用于更多的生产环境。因此亟待本领域技术人员解决此问题。

在实际应用中,为了使用产能的需要,通常在物料转移设备对物料进行转移的过程中设置为移动式的,具体的,如图8所示,物料转移设备6具体可以包括抓取机构61和轨道62,抓取机构61沿轨道62移动,其中抓取机构61在轨道62上移动的过程中抓取机构61对物料进行抓取的动作,其中,测试设备对应设于轨道的至少一侧,将测试设备的对接端朝向抓取机构设置,抓取机构能够克服测试装置的干涉,便于将物料送入到测试设备中进行固定测试的工作,同时,有利于测试设备便于成组布置,具体的,抓取机构可以为机械手、机器人或其他。当然在测试设备少的时候,也可以不设置轨道,降低制造成本。

作为本实施例中夹具的另一种实施方式,该夹具也可包括夹爪4,将夹爪4通过滑块固定于夹具导向装置,例如导轨上,夹爪4的夹持手柄将电路板的一侧进行夹持固定,之后在夹具导向装置的带动下将电路板在上下料区2和工作区1之间输送并调整夹爪4在工作区1的位置。
如图4所示,上述的夹具导向装置包括夹具驱动件、设于所述固定夹具312的至少一端部的耳板322以及传动带组件323,所述耳板322与所述传动带组件323的传动带固定连接,所述夹具驱动件与所述传动带组件323的带轮连接,本实施例中,固定夹具312为固定板,将固定板的一端与耳板322的一端连接,耳板322的另一端与传动带组件323的传动带连接,具体的,夹具驱动件为夹具驱动电机,夹具驱动电机的动力输出端与传动带组件323的带轮固定连接,在夹具驱动电机的驱动下,带轮带动传动带运动,进一步带动夹具,包括联动夹具31或夹爪4,在上下料区2和工作区1内往复运动,实现电路板的送入与输出。

参见附图2或4,本实施例中的固定单元可以为一对联动夹具31和一对夹爪4,其中上下方向设置有一对联动夹具31,左右方向设置有一对夹爪4,一 对联动夹具31的夹持槽311相对设置,一对夹爪4的夹持手柄相对设置,在布置到上下料机构中时,联动夹具31对电路板的竖直方向进行夹持固定,夹爪4对应设置于工作区1内,对电路板的水平方向进行夹持固定,将电路板的竖直两侧分别对应的放置在联动夹具31的夹持槽311内,由夹具导向装置带动一对联动夹具31将电路板从上下料区2输送至工作区1,然后电路板上下两侧的夹爪4对电路板的水平方向进行夹持固定,提高了夹持的效果。
作为本实施例中固定单元的另一种实施方式,上述固定单元中的联动夹具31可以对电路板的水平方向进行夹持固定,夹爪4对电路板的竖直方向进行夹持固定,即调换夹爪和联动夹具的设置位置。当夹爪4对电路板的设置方向进行夹持固定时,夹爪4直接固定于夹具导向装置中的传动带组件323的传动带本体上,由传动带携带在上下料区2和工作区1之间往复运动;在联动夹具31对电路板的水平方向进行夹持固定时,在夹具导向装置的带动下,其能够相对电路板的上下两侧进行靠近与远离,进而实现对电路板水平方向的夹持固定,提高了稳定效果。
