Description

销钉位置调节装置及钻孔机
本申请要求在2020年04月08日提交中国专利局、申请号为202010269652.0的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及印刷电路板(Printed Circuit Board，PCB)加工设备技术领域，例如涉及一种销钉位置调节装置及钻孔机。
背景技术
在PCB板的生产过程中，通常需要利用钻孔机对PCB板进行钻孔，而在钻孔前，通常需要利用销钉将PCB板固定在工作台板上。为了使钻孔主轴的加工坐标系与PCB板的定位坐标系高度重合，需要对销钉的位置进行调节。但是，在相关技术中，通常通过人工对销钉的位置进行手动调节，而手动调节不仅操作复杂，调节时间长、效率低、精度差，而且手动调节时钻孔机需要停机，钻孔机在停机状态下会从热机状态变为冷机状态，而工作台板等部件会产生热胀冷缩从而引起位置精度变化，同时停机会影响钻孔机的稼动率，另外，手动调节时工作台板上需要开设一些调节孔等结构，而PCB板的板面容易在调节孔处下陷，从而会导致钻孔精度降低。
因此，亟需一种新型的销钉位置调节装置以解决上述技术问题。

本实施例提供的销钉位置调节装置，通过第一调节机构2和第二调节机构3在底板1上的移动，能够实现对第一销钉100和第二销钉200位置的自动调节，从而有利于提高位置调节的效率，保证第一销钉100和第二销钉200的位置精度以及钻孔精度，同时还可以在钻孔机不停机的状态下进行位置调节，保证钻孔机的稼动率；同时通过设置第一夹紧组件22和第二夹紧组件32，能够在第一销钉100和第二销钉200的位置调节完成后对第一销钉100和第二销钉200进行夹紧固定，使第一销钉100和第二销钉200稳定地保持在所需位置上，提高第一销钉100和第二销钉200位置的稳定性。

可选地，如图1和图4所示，第二调节机构3沿第一方向可移动地设置在底板1上，第一调节机构2沿第二方向可移动地设置在第二调节机构3上。即通过第二调节机构3带动第一调节机构2沿第一方向移动，使第一调节机构2能够实现沿第一方向和第二方向的移动。按照此种方式设置，可以减少驱动组件的使用数量，在第一方向和第二方向上均设置一组驱动组件即可，从而有利于简化第一调节机构2和第二调节机构3的结构，提高布局的紧凑性，同时有利于降低成本。当然，在其他实施例中，也可以在本实施例的基础上增加一组驱动组件，单独为第一调节机构2配备两组驱动组件，以实现第一调节机构2沿第一方向和第二方向的移动。
本实施例提供的销钉位置调节装置的工作原理如下：利用钻孔刀具或者测试探针对第二调节机构3上的第二销钉200进行第一方向和第二方向的试碰，得到第二销钉200的当前坐标值，以第二销钉200的当前坐标值为基准，控制第二调节机构3沿第一方向移动，整体调整第一销钉100和第二销钉200沿第一方向的位置，以满足第一方向上的位置要求；然后利用钻孔刀具或者测试探针对第一调节机构2上的第一销钉100进行第一方向和第二方向的试碰，得到第一销钉100的当前坐标值，以第一销钉100的当前坐标值为基准，控制第一调节机构2沿第二方向移动，调整第一销钉100和第二销钉200之间的距离，以满足第二方向上的位置要求；调整完成后，第一夹紧组件22夹紧固定第一销钉100，第二夹紧组件32夹紧固定第二销钉200。
