Description

在 PCB板上自动插件的方法、 系统及设备 技术领域
本发明属于电子制造领域,尤其涉及在 PCB板上自动插件的方法、 系统及 设备。 背景技术
在印刷电路板 (Printed Circuit Board, PCB)上的可自动插件的元器件一般可 分为三类: 1、 跳线( Jumper Wire ); 2、 轴向元件( Axial Lead Parts ); 3、 径向 元件(Radial Lead Parts )。 在装着可自动插件的元器件的过程中, 对不同元器 件必需釆取不同插件工艺方式,例如: 利用 JVK机器完成跳线插件、利用 AV 机器完成轴向元件插件、 利用 RH机器或 RHS机器完成径向元件插件。 当需要 印刷电路板上安装较多的可自动插件的元器件时, 其装着路径方案的数目就较 为庞大。 在这些路径方案中, 各种路径方案的执行效率有一定的差別, 即采用 一种路径方案进行插件的速度, 可能会比采用另一种路径方案进行插件的速度 快。
目前, 用户采用一些方案, 并编写相应的 '数控程序 ( NC程序)来控制实 际插件过程。 而在实际生产中, 由于需要插件的元件种类多、 点数多、 PCB板 面积大、 元件分布不规则 (此以坐标、 角度为衡量标准)等情况下, 人工编写 的插件程序在考虑机器各种参数的影响下很难或者根本无法准确选择一条较为 理想的路线, 这就容易造成程序中 X、 Y坐标, 料站(Feeder ), 扭角 (Insertion Angle ) 以及跨距 ( Insertion Pitch ) 的大范围来回变动, 使机器频繁出现'等待 同步,的现象, 严重的可明显看出机器在插件过程中的稍微停顿,从而导致插件 效率较 ^ 增加了插件时间。
例如, 使用插件机器进行一种 CRT电视印刷电路板插件, 其 AI生产过程 数据分析如下, 其中一种( 404 X 257 X 1.6mm ) PCB生产数据大概如下: 总插
1 确认本 件跳线数: 110点, 其中测试 JVK机器跳线插件平均时间约 34秒 PCB , 则平 均约为 0.31秒 /点; 轴向元件数量: 161点, 元件品种' 61类, 其中测试 AVK机 器轴向元件插件平均时间约 51秒/ PCB, 则约 0.317秒 /点; 径向元件数量: 159 点, 元件品种 48类, 其中测试 RH机器径向元件插件平均时间约 77秒 PCB, 则平均约为 0.484秒 /点。 根据此数据我们对照 Panasert机器的特征参数就会发 现, 其生产过程实际上并没能非常最大限度的利用机器。 以下我们针对此四类 型机器作简要分析: .
( 1 )、针对跳线( Jumper Wire )插件机器 JVK:机器的理论最快速度为 0.13 秒 /元件, (此速度是限制在严格的机器条件上), 插件元件无极性区分, 只要采 取同方向一次性完成插件方式, 例如先完成所有 0度角 (X方向)元件插件, 再进行 90度角 (Y方向)元件插件, 而插件速度只 赖程序所选择的路线、 跨距的变化。 但人工编写的插件程序往往不可能考虑到这些, 所以在程序路线 与跨距的大幅度变化过程中会促使机器实际插件速度减慢, 基本上无法达到其 最快的理论速度。在目前我们实际生产中对一块电视 PCB以 120个插件跳线元 件计算, 平均需要 0.28-0.30秒 /元件;
( 2 )、 针对轴向元件(Axial Lead Parts )插件机器 AVK: 在考虑料站(Z 轴)移动不超过 3站, X、 Y坐标移动均不超过 5cm, 跨距无变化, 元件厚度 数据无变化情况下, 机器理论最快速度: 0度角: 0.18秒 /元件, 90度角: 0.15 秒 /元件, 180度角: 0.3秒 /元件, 270度角: 0.27秒 /元件。 但目前人工编程手 段很难满足对所有这些参数考虑, 实际插件程序会出现 X、 Y坐标,料站 Z轴、 跨距 T轴以及扭角大幅度的移动插件, 这就造成插件速度明显緩慢。 对实际测 量平均速度为: 0.3-0.35秒 /元件。
( 3 )、 针对径向元件( Radial Lead Parts )插件机器 RH: 同样面临着类似 AVK的编程问题, 需考虑机器 X、 Y坐标移动, 料站(Z轴)移动, 元件高度 与插件扭角的变化, 其理论的最快速度为: 0.45秒 /元件; 插件机器 RHS: 插件 程序需要考虑三方面影响因素, 一为 X、 Y坐标移动路线, 二为插件扭角, 三 为元件高度,其中二和三是考虑下一插件必要参数,其理论的最快速度为: 0.45 秒 /元件。
综上所述, 虽然现有的插件控制程序可以完成插件任务, 但现有插件控制 程序的目标仅为准确地完成插件任务, 而未考虑到插件效率, 从而现在的插件 程序插件效率往往较低。 当用户想改善插件效率时, 一般通过人为地对插件控 制程序进行修改, 但人为修改时往往容易注意到某些参数数据的改善, 而忽视 了另一些参数数据的改善, 因此, 人为地修改不仅耗费大量的人力, 而且并无 法明显地改善插件效率。 发明内容
本发明实施例的目的在于提供在 PCB板上自动元器件插件的方法, 旨在解 决现有插件控制程序的插件效率较低, 通过人为地方式改进插件控制程序时, 不仅耗费大量人力, 而且无法明显地改善插件效率的问题。

为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实 施例, 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅 仅用以解释本发明, 并不用于限定本发明。
在本发明的实施例中, 通过优化程序对原始的插件程序中的插件参数进行 调整, 根据调整后的参数生成优化的插件路径, 并根据优化后的插件路径进行 插件, 从而不仅改进了插件效率, 而且避免了人为地修改插件程序导致人力耗 费, 插件效率改进不明显的问题。
图 1示出了本发明实施例提供的在 PCB板上元器件的插件方法流程,详述 如下:
在步骤 S101中,获取插件程序数据。插件程序数据存在于各种插件程序文 件中, 例如, 后缀名为 NCD, UDR, POD的插件程序文件。 通过读取这些程 序文件即可获取插件程序数据。 其中, 后缀名为 NCD的文件中记录了所有操 作点的坐标等数据; 而后缀名为 UDR的文件记录了插件程序中控制数据项 (STEP)所对应的机器类型, 因此, 利用后缀名为 UDR的文件可判断插件程序 所熟悉的机器类型; 后缀名为 POD 的文件记录了操作点的总偏移坐标 ( OFFSET )。
在步驟 S102中,拆分插件程序数据,获取参数数 。将插件程序数据拆分 为多个 STEP。针对每个 STEP,获 ^目应的参数数据,例如: /值, G值, M值, T值, X值, Y值, Z值, V值, W值, 与元件说明参数项。
在步驟 S103中,分离跳跃项。在插件程序中会存在跳跃项, 为了避免因执 行这些跳跃项而影响插件程序的执行效率, 作为本发明的实施例, 将跳跃项进 行分离。 由于跳跃项的序标记 /值 = /7, 当将插件程序拆分的多个 STEP (控制 项)时, 可以根据参数 /值判断出跳跃项, 即在所有的 STEP 中查找序标记为 / 值 = 11的 STEP , 从而可以分离跳跃项。
在步骤 S104中, 删除无效的 STEP。 在插件程序中还可能存在一些无效的 STEP。 作为本发明的实施例, 删除无效的 STEP。 由于当 STEP的 G值不为 0 时, 该 STEP是无效的。 当将插件程序拆分的多个 STEP时, 可以根据 G值来 判断 STEP是否是无效的, 进而删除所有无效的 STEP。
在步骤 S105中,根据分离出跳跃项,以及删除了无效 STEP后的插件程序, 计算出元器件的插件路径。
根据分离了跳跃 STEP, 以及删除无效 STEP后的插件程序,模拟插件头的 移动路径。 作为本发明的实施例, 由于使用 JVK机器对跳线进行插件, 使用 AVK机器对轴向元件进行插件,使用 RH或 RHS机器对径向元件进行插件(由 于 RHS机器是 RH机器的升级版本,一般仅使用其中一种机器对径向元件进行 插件) , 在插件程序中有针对这三种自动元器件的 STEP, 因此, 相应地有三 条移动路径。
在步骤 S106中,计算路线移动初始总距离,初始总时间。针对每一种插件 机器, 根据其插件头移动路径, 计算插件头从机器原点开始经每一操作点后回 到该机器原点的路径距离, 即这种机器的初始路线距离。 利用初始路线距离除 以该插件机器理论平均速度的值, 即得到该机器的初始时间值。 三种机器的初 始路线距离之和即为初始总距离。三种机器的初始时间值之和即为初始总时间。
在步骤 S107中,根据插件程序,选择插件头的起始点。作为本发明的实施 例, 可以以 PCB的需插件平面的两边的中点为分割点,从分割点作这两边的平 行线, 以该平行线为分割线, 将 PCB的插件表面分割成大小相同的四个部分。 以左上角的部分为第一象限区, 以距离机器原点的直线距离最远的插件点作为 起始点。 该起始点即为程序原点。
在步骤 S108中,调用优化程序对插件参数进行调整。作为本发明的实施例, 优化程序可以包括 JVK优化程序, AVX优化程序, RH优化程序, 以及 RHS 优化程序中的部分或者全部。 由于在后缀名为 UDR的文件中, 记录了插件程 序中 STEP所对应的机器类型。 根据该文件即可识別出机器类型, 从而选择相 应的优化程序对该机器的路径进行优化。 即通过判断机器的类型, 相应也就得 到了元器件的类型, 即可选择相应的优化程序。
在步骤 S109中,将优化处理后的插件程序合成新插件程序文件。为了保存 优化后的路径, 可以将优化后的插件程序合成新的插件程序文件, 从而下次插 件时可直接通过读取该文件获得优化后的路径。 新的插件程序文件仍为后缀名 为 NCD, UDR, POD的三种文件。
在步骤 S110中, 才艮据新插件程序, 获取优化后的插件头的移动路径。 在步骤 S111中,计算优化后的路径的优化总距离,优化总时间。针对每一 种插件机器, 根据其新的移动路径, 计算插件头从程序原点开始经每一操作点 后回到程序原点的路径距离, 即得到该机器的优化路线距离。 利用该优化路线 距离除以该机器理论平均速度的值, 即得到优化时间。 三种机器的优化路线距 离之和即为优化总距离。 三种机器的优化时间值之和即为优化总时间。
在步骤 S112中, 判断优化总距离, 优化总时间是否分别小于初始总距离, 初始总时间。 由于对于插件程序优化前后来说, 机器理论平均速度为一常数, 因此, 仅比较优化前后的总距离的大小即可。
在步骤 S113中,显示插件程序当前已经处于优化状态的提示信息。 当优化 前后的总距离, 总时间不发生变化时, 可能由于有些插件程序可能已经进行了 优化, 而操作人员并不清楚这一情况而再次发出优化命令, 此时, 可以显示原 程序已处于优化状态的提示信息, 并且不改变原始插件程序文件。
在步骤 S114中,显示插件程序已经优化完成的提示信息,并且输出优化后 的插件程序文件。 当优化总距离, 优化总时间, 小于初始总距离, 初始总时间 时, 输出插件程序已完成优化的提示信息, 并且输出 NCD, UDR, 以及 POD 插件程序文件。
在步骤 S115中, 根据优化后的插件路径进行插件。 整的实施流程, 详述如下:
在步驟 S201中,参数传递交换。获取主插件程序中所有参数值,例如坐标、 跨距等所有参数的值。
在步骤 S202中,针对该跳线插件的路径的 0, 90度两个方向,将同一方向 的所有跳线插件点连续排列。 由于使用 JVK机器插跳线元件时, 在 PCB板上 只区分 0度及 90度,即 X、 Y方向,将 0度方向的所有跳线插件点集合为一组, 以及将所有 90度的跳线插件点集合为一組,并将两組跳线插件点连续排列,从 而 JVK机器在执行跳线操作时, 可将 0 ( 90 )方向的所有跳线插件点一并执行 插件, 再执行剩余的 90 ( 0 )上的插件操作, 从而避免了机器的插件头在 0, 90 方向上的经常性切换, 从而节约了时间。
在步驟 S203 中, 计算所有跳线插件点的跨距, 并按跨距的大小顺序, 将 所有跳线插件点进行排序
按照所有跳线插件点的跨距的大小, 对插件点进行排序(可以是从小到大 或从大到小) , 作为本发明的实施例, 可以将所有插件点依次分为多个组。 这 样, 在插件时, 由于排序后的插件点的跨距变化幅度一般会比排序前的插件点 的跨距变化幅度小, 从而可減少机器的跨距时间耗费。
在步骤 S204中, 针对 JVK插件程序, 确定起始点。 作为本发明的实施例, 可以选择离机器原点最远的点作为起始点。
在步驟 S205中, 获取第 i个跳线插件点 Mi。 i为一可变参数, 其值域为 2 到 P1之间的所有整数, 包括 2, 及 P1 , 并且 i的初始值为 2。 其中, P1为 JVK 插件程序中总 STEP的数目。
在步骤 S206中, 获取第 j个跳线插件点 Mj。 其中, j为一可变参数, 其值 域为 i+1到 P1之间的所有整数, 包括 i+1 , 以及 PI, 并且其初始值为 i+1。
在步骤 S207中, 判断第 i个插件点 Mi与第 i- 1个插件点 的距离是否 小于第 j个插件点 Mj与第 i-1个插件点 Μμι的距离。当 与 ΜΜ的距离小于 Mj 与 的距离时, 执行步骤 S209。
在步骤 S208中, 判断第 i个插件点的跨距是否小于第 j个插件点的跨距。 当第 i个插件点与第 i-1个插件点的距离不小于第 j个插件点与第 i- 1个插件点 的距离时,判断第 i个插件点的跨距是否小于第 j个插件点的跨距。 当第 i个插 件点的跨距小于第 j个插件点的跨距时, 执行步驟 S210。
在步骤 S209中, 交换插件点 Mj与插件点 Mi位置。即交换这两个插件点的 排序顺序, 即交换这两个插件点的插件顺序。 '
在步骤 S210中, j的值加 1。 当第 i个插件点的跨距大于或等于第 j个插件 点的跨距时, 使 j的值加 1。
在步骤 S211中, 判断 j是否小于或等于 Pl。 判断增加 1后的 j是否小于 或等于 P1, 当小于或等于 P1时返回执行步骤 S206。
在步骤 S212中, 使 i的值增加 1。 当增加 1后的 j大于 P1时, 使 i的值增 加 1。
在步骤 S213中,判断增加 1后的 i值是否小于 Pl。判断增加 1后的 i值是 否小于 P1 , 当小于 P1时, 返回步骤 S205。
在步驟 S214中, 输出经过调整后的所有参数。 当增加 1后的 i值不小于 P1时, 说明排序已经完成, 则输出经过调整后的所有参数。
在上述步骤中, 步骤 S205到步骤 S211中, 实际上是对所有跳线插件点进 行再次排序, 从而使每一跳线插件点与其前一跳线插件点的距离不大于其后任 意跳线插件点与其前一跳线插件点的距离, 并且相邻的两个跳线插件点之间的 跨距差增大, 从而使调整插件参数后的插件程序对应的跳线的插件路径得到了 优化。
图 3示出了本发明实施例提供的对 AVK机器的插件程序的插件参数进行调 整的实施流程, 详述如下:
在步驟 S301中,参数传递交换。获取主插件程序中所有参数值,例如坐标、 跨距等所有参数的值。
在步骤 S302中, 针对轴向元件插件路径的 0, 90, 180, 270度四个方向, 将同一方向的所有轴向元件插件点连续排列。 由于使用 AVK机器处理轴向元 件时, 需要考虑元件的极性, 即 AVK机器处理轴向元件时, 可能在 0度, 90 度, 180度, 以及 270度进行操作。 为了避免了机器的插件头在此四个方向上 的经常性切换, 分别将每一角度上的所有轴向元件插件点集合为一组, 即每个 角度对应一组, 从而 AVK机器在执行轴向元件插件时, 一组一組地进行插件 , 即当完成了一个角度上所有的轴向元件的插件后再进行下一角度的插件, 从而 避免了机器的插件头在四个方向上的经常性切换, 从而节约了时间。
在步骤 S303中, 计算所有轴向元件插件点的跨距, 并按跨距的大小顺序, 将所有轴向元件插件点进行排序。
按照所有轴向元件插件点的跨距的大小, 对插件点进行排序(可以是从小 到大或从大到小),作为本发明的实施例,可以将所有插件点依次分为多个組。 这样, 在插件时, 由于排序后的插件点的跨距变化幅度一般会比排序前的插件 点的跨距变化幅度小, 从而可减少机器的跨距时间耗费。
在步骤 S304中,针对同一轴向元件插件头,计算所有插件点中每两个插件 点的距离。 JVK插件机器¼有一种插件头, 而 AVK插件机器则需要进行电阻, 二极管等多种元件的插件, 因此, AVK机器有多个插件头。
在步驟 S305中, 将 PCB分成多个象限, 计算各轴向元件插件头在每个象 限中的插件点的数目, 即统计每一轴向元件插件头对应的所有轴向元件插件点 所在的区域。 例如, 可以将 PCB分为四个象限, 其方法可参照步骤 S107。 当 然, 也可以将该四个象限进一步划分。
在步骤 S306中, 统计 X方向的 0度, 180度, Y方向的 90度, 270度的 扭角数目。

在步骤 S309中,根据各轴向元件插件头对应的插件点在各个象限的分布情 况, 对所有插件点进行排序。 作为本发明的实施例, 可以根据各轴向元件插件 头对应的插件点在各个象限的分布情况, 对每一轴向元件插件头进行标记。 标 记方法如下: 轴向元件插件头对应的所有插件点均分布在第一象限, 则将该插 件头标记为: 1区间插件头 Z1 ; 轴向元件插件头对应的所有插件点均分布在第 二象限, 则将该插件头标记为: 2区间插件头 Z2; 其它的插件点均分布在一个 象限的插件头相应地类似标记为: 3区间插件头 Z3 , 4区间插件头 Z4; 分布在 第一, 二象限, 则将该插件头标记为: Z1-2, 其它的插件点分别分布在二个象 限的插件头相应地类似地标记为: Zl-3 , Zl-4, Z2-3 , Z2-4, Z3-4; 分布在第 一, 二, 三象限, 则将该插件头标记为: Z1-2-3 , 其它的插件点分别分布在三 个象限的插件头相应地类似地标记为: Zl-2-4, Zl-3-4, Z2-3-4; 分布在第一, 二, 三, 四象限, 则将该插件头标记为: Zl-2-3-4。
然后, 根据轴向元件插件头的标记, 对所有的插件点进行排序。 作为本发 明的实施例 ,执行径向元件插件的区域顺序是从笫一象限依次执行到第四象限, 因此, 插件点排序顺序为: 1.区间插件头 Z1对应的所有插件点, Z12对应的所 有插件点, 然后依次为: 2区间插件头 Z2, Z2-3 , 3区间插件头 Z3, Z3-4, 4 区间插件头 Z4, Zl-4, Zl-3-4, Zl-3 , Z1 -2-3-4, Z2-3-4, Z2-4, Zl-2-3 , Z1-2-4 对应的所有插件头。
在步骤 S310中, 获取第 i个轴向元件插件点 Ni。 i为一可变参数, 其值域 为 2到 P2之间的所有整数, 包括 2, 及 P2, 并且 i的初始值为 2。 其中, P2为 AVK插件程序中总 STEP的数目。
在步骤 S311中, 获取第 j个轴向元件插件点 Nj。 其中, j为一可变参数, 其值域为 i+1到 P2之间的所有整数, 包括 i+1 , 以及 P2, 并且其初始值为 i+l。
在步驟 S312中,判断第 i个插件点 与第 i-1个插件点 的距离是否大 于或等于第 i-1个插件点 Νμι与第 j个插件点 Nj的距离。 当 Nj与!^!的距离大 于 ^与!^!的距离时, 执行步骤 S316。
在步骤 S313中,判断第 j个插件点与第 i-1个插件点的扭角之差的绝对值, 是否小于或等于, 第 i个插件点与第 i-1个插件点的扭角之差的绝对值。
当 Nj与 Ni4的距离小于或者的等于 Ni与 ΝΗ的距离时,判断 Nj与 Nw的扭 角之差的绝对值, 是否小于或等于, 与 NH的扭角之差的绝对值。 当 Nj与 !^的扭角之差的绝对值, 大于, Ni与 Ni.i的扭角之差的绝对值时, 执行步驟 S316。
在步骤 S314中,判断第 j个插件点与第 i-1个插件点的跨距之差的绝对值, 是否小于或等于, 第 i个插件点与第 i-1个插件点的跨距之差的绝对值。 当 Nj 与 1^4的扭角之差的绝对值, 小于或等于, 与 >½的扭角之差的绝对值时, 进一步判断 Nj与 Ni4的跨距之差的绝对值, 是否小于或等于, Ni与 跨距 之差的绝对值。 当 Nj与 N 的跨距之差的绝对值大于 Ni与 Νμι的跨距之差的绝 对值时, 执行步骤 S316。
在步骤 S315中, 交换第 j个插件点与笫 i个插件点的顺序。
在步驟 S316中 , j的值增加 1。
在步骤 S317中, 判断第 j个插件头 与第 i- 1个插件头 Z 之差的绝对值 是否小于 a, 其中 a为正整数。 根据需要, 可以调整 a的大小, 并且, 根据经 验.3为 a的一个较佳值。 当 与 之差的绝对值小于或等于 a时, 返回步骤 S311。
在步骤 S318中, 使 i的值增加 1。 当 与 ΖΜ之差的绝对值大于 a时, 使 i的值增加 1。
. 在步骤 S319中, 判断 i是否小于 P2。 当 i小于 P2时, 返回步骤 S310。
在步骤 S320中, 输出经过调整后的所有参数。 当增加 1后的 i值不小于
P2时, 说明排序已经完成, 则输出经过调整后的所有参数。
在上述步骤中, 步骤 S310到步骤 S319, 实际上是对所有轴向元件插件点 进行再次排序, 从而使每一轴向元件插件点与其前一轴向元件插件点的距离不 大于其后任意轴向元件插件点与其前一轴向元件插件点的距离, 并且该轴向元 件插件点与其前一轴向元件插件点的扭角之差的绝对值小于该其后任意轴向元 件插件点与该其前一轴向元件插件点的扭角之差的绝对值, 并且该轴向元件插 件点与该其前一轴向元件插件点的跨距之差的绝对值小于该其后任意轴向元件 插件点与该其前一轴向元件插件点的跨距之差的绝对值, 从而使调整插件参数 后的插件程序对应的轴向元件的插件路径得到了优化。 整的实施流程, 详述如下:
在步骤 S401中,参数传递交换。获取主插件程序中所有参数值,例如坐标、 跨距等所有参数的值。
在步骤 S402中,针对径向元件插件路径的 0, 90度两个方向,将同一方向的 所有径向元件插件点连续排列。 由于使用 RH机器处理径向元件时, 只区分 0度, 及 90度。为了避免了机器的插件头在此两个方向上的经常性切换,将 0度方向的 所有径向元件插件点集合为一组, 以及将所有 90度的径向元件插件点集合为一 组, 并将两组径向元件插件点连续排列, 从而 RH机器在执行径向元件插件时, 可将 0 ( 90 )度方向的所有径向元件插件点一并执行插件, 再执行剩余的 90 ( 0 ) 度方向上的插件操作, 从而避免了机器的插件头在两个方向上的经常性切换, 从而节约了时间。
在步骤 S403中, 针对同一径向元件插件头, 计算所有插件点中每两个插件 点的巨离。
