Description

一种超长卡槽PCB的成型加工方法 技术领域
本发明属于PCB加工技术领域，具体涉及一种超长卡槽PCB的成型加工方法。
 背景技术
电源模块、智能光电、数字化系统等设备为了维修更换方便，往往采用拔插式三维安装模式。即拿住板子的一边让三边插入预先设计好的卡槽内，产品后期的检测与维修不用拆除固定螺丝，拔出来即可方便维修与保养。而此类板卡的印制板在加工时需要对其中的三边进行斜边加工。
在PCB行业内有2种自动斜边机，一种斜边机的常规加工尺寸只有420mm左右，对于超过尺寸的产品无法加工，另一种对长度虽然无限制，但对宽度有限制。对于420-1500mm的超长卡槽产品均无法在一台PCB斜边上加工完成。从理论上讲可以采用履带式斜边机生产长边，再用自动斜边机的手动功能生产短边，虽然效率低但可以完成。斜边机属于高度精密的电子设备，平均价格在100万元以上，即使批量性的PCB大厂也只有一种斜边机，因此采用这种方式不仅投资大，而且长期会导致设备产能的闲置。
 技术问题
部分工厂为解决此类产品采用自制的手动斜边机生产，这种斜边机需要作业员用手推动PCB板通过高速旋转的斜边刀完成斜边生产。这种设备对作业员的技能要求高，存在操作难度大，精度差、效率低的问题，只适用于少量样板生产。还时常伤及作业员的手指存在严重的安全隐患，也逐渐被PCB工厂淘汰。
 技术解决方案
有鉴于此，本发明从产品与设备的工艺能力入手，通过对数控机床设备的工艺能力进行更深层次的技术开发，设计专用的超长卡板类印制电路板斜边加工流程，确保产品能批量、快速安全地生产、提升产品质量，解决手动斜边机效率慢、品质差、存在严重安全隐患，常规斜边机无法生产超长卡板的技术难题。
本发明的技术方案为：
一种超长卡槽PCB的成型加工方法，其特征在于，包括以下步骤：
S1、V-CUT机-CNC成型加工；
选择满足挂生产长度能力的挂PIN钉V-CUT机及与斜边角度相同的V-CUT刀，按斜边后所剩下的厚度设计V-CUT的余厚，并在产品资料外框设计V-CUT挂孔，先用V-CUT机加工插入卡槽的三边，然后再用CNC成型加工即得到成品；
S2、超长板卡槽板加工资料的设计；
依据卡槽板斜边的深度与宽度设计V-CUT资料与锣带，V-CUT线的中线为外形线的边线；设计锣带，外形线的边线为V-CUT线的中线，在边框四周设计外定位，板内内定位，公差按±0.1mm控制；
S3、超长卡槽板的加工；
将超长卡槽板板按正常流程制作到成型工序；
S4、超长板卡槽板尺寸质量检测；
加工V型槽时超长板卡槽板，需要用V-CUT残厚测量仪测量V槽的余厚，CNC成型后需要检查斜边的尺寸是否满足设计要求。
进一步的，所述步骤S1中，所述V-CUT机为挂生产长度能力为1500mm的挂PIN钉V-CUT机。
进一步的，所述步骤S3中，所述成型工序，先由V-CUT机完成V槽的加工，然后再由CNC成型机沿着V型槽的底部作成型加工，最终完成PCB的卡槽斜边。
进一步的，所述步骤S1中，V-CUT机的加工方法为：以卡槽的三边外框的边线为准分别在三边的板边设计V-CUT挂孔，每个挂孔间的中心距离为100mm，保障三边均能挂板生产；以V型槽的中线为卡槽的三边外框的边线设计V-CUT加工程序。
进一步的，所述步骤S1中，所述CNC成型加工的方法为：以V型槽中线为成型加工的边线，在三边设计CNC成型加工锣带，具体包括按锣机台板的最大尺寸设计锣带，对于尺寸超出成形机加工尺寸的部分按其倍数设计锣带，待前未超出按锣机台板的最大尺寸部分生产完成后依次再生产剩余部分。
更进一步的，锣机台板的最大尺寸为1400mm以下设计2条，1500mm以下设计3条。
更进一步的，二条以上的锣带可以设计在4-6轴的成型机的另一个轴，若设计在同一个轴需要将卡槽板旋转180度，使得尺寸符合设计要求。
更进一步的，所述步骤S3中，所述成型工序具体包括：S31、V型槽的加工：选择生产加工能力为1500mm的挂PIN钉V-CUT机，选择与斜边角度要求相同的V-CUT刀。调取已制作的V-CUT资料，调整参数，将板挂在机器内按设备的操作流程切割超长卡槽板三边V型槽，并首件确认余厚，批量生产至到完成整批产品；S32、CNC成型加工：选择常规4-6轴成型机1台，对于长度小于700mm以下的产品，可以采用一条锣带按常规工艺完成，对于大于700mm的产品，在完成第一条锣带的生产后，还需要对剩余的部分进行加工，按照工程给出的锣带的生产程序，调整参数按CNC设备的操作流程生产，公差按±0.1mm控制，将所有的板生产完。
 有益效果
1、生产效率的提升：长度为420-1500mm的超长板卡槽板的三边已超出了现有自动化斜边机最大加工能力而无法生产，只能采用手工方式生产，平均每分钟0.2-0.5m.本发明开发设计了一种利用V-CUT机快速自动化V割技术代替斜边机加工超长板卡槽板的技术，V-CUT机平均每分钟可生产40m以上，平均可以快速提升生产效率100倍以上，能够满足企业大规模生产的需要。
2、新技术未增加流程和设备、从技术的角度优化了超长板卡槽板的工艺流程，不需要高技术的作业员手工操作降低了生产难度，效率的提升节省了设备的加工时间成本、人工成本及水电成本，外协生产成本在每平方米800元左右，属于高附加值加工项目，采用新技术实现自主生产可降低生产成本，对外代加工可获得高额加工利润。
3、新技术从设计开始就依据卡槽边的余厚要求及角度设计要求设计余厚和精选V刀角度，通过V槽深度控制能完全保证V槽尺寸合格，再通过锣边确保整体尺寸满足设计公差要求，产品可快速插入卡槽、无松动脱落的风险。
4、超长卡槽板加工工艺的开发，为企业节省了时间、人工等加工成本，在确保安全生产的基础上效率提升100倍以上，品质合格。在技术不受制于人的前提下，企业也一定以此高、精、尖技术作为最新的利润增涨点，获得更多的超长板卡槽类PCB产品的订单，更高的利润回报。
本发明提供一种在PCB成型加工工艺中利用大尺寸挂PIN钉V-CUT机和V-CUT刀的切割功能代替斜边机加工超长V型卡槽的PCB产品制作工艺，一种可快速提升超长V型卡槽PCB产品生产效率的制作方法。本发明依据超长V型卡槽产品斜边的斜边角度及外型尺寸设计V槽加工的方法及流程，可保证V-CUT机加工代替常规手动斜边机加工后产品质量合格，能放入插入卡槽内满足客户要求。
