Description

SMT设备快速制程系统及方法
技术领域
本发明涉及一种表面组装技术领域, 特别是涉及一种应用于 SMT 设备中的快速制程系 统及方法。 背景技术
SMT就是表面组装技术 (Surface Mounted Technology 的縮写), 是目前电子组装行 业里最流行的一种技术和工艺。 它将传统的电子元器件压縮成为体积只有几十分之一的器 件, 从而实现了电子产品组装的高密度、 高可靠、 小型化、 低成本, 以及生产的自动化。 这 种小型化的元器件称为: SMY 器件 (或称 SMC、 片式器件)。 将元件装配到印刷 (或其它 基板) 上的工艺方法称为 SMT 工艺。 目前, 先进的电子产品, 特别是在计算机及通讯类电 子产品, 已普遍采用 SMT工艺。 国际上 SMD器件产量逐年上升, 而传统器件产量逐年下 降, 因此随着进间的推移, SMT技术将越来越普及。 相关的组装设备则称为 SMT设备, 而 SMT设备在产线进行生产作业时由其 SMT制程系统控制。
在现有技术中, 行业内的 SMT编程系统无外乎有两种: 一种是设备商本身自带的软件 系统, 另一种是第三方开发的编程系统。 设备商提供的 SMT编程系统侧重于设备的运作性 能优化, 即设备在生产时规定时间内的生产贴装效率, 而忽视了离线时的编程效率; 另外一 种是第三方软件公司提供的 SMT编程系统, 侧重于 EDA (电子设计自动化) CAD 设计研 发数据和 Gerber (光绘文件) 数据的转换, 由于设备的运作参数的不开放性, 第三方的技术 方案无法很好的提升设备的运作性能, 尤其是现在主流的模组化贴片机, 设备运作的参数无 法得到, 实已成为本领域从业者亟待解决的技术问题。
随着行业的变化, 小批量多品种的生产占了很大比例, 行业内现有的主要流程是: 将设 计布线产生的坐标文件、 EDA CAD或 Gerber转换到系统内, 仅利用坐标数据结合 BOM文 件生成贴片机程序。 但一个完整的程序主要需要做以下几部分工作: 1, 正确的贴装坐标数 据, 坐标和角度需要正确; 2, 元件资料库数据; 3, 较好的程序优化结果, 最大化提升设备 的运作性能。 针对上述的三部分, 第三方软件公司提供的 SMT 编程系统通常只做到第 1 项, 而第 2、 3 项则由设备商本身自带的软件系统完成, 但设备软件系统中通常需要操作者 或使用者进行手动生成第 2项工作, 即元件资料库数据的创建或修改, 才能确保第 3项工作 的完成较为理想。 总而言之, 目前所有 SMT 设备制程系统主要不足在于只利用了坐标数 据, 需要花大量的时间花在选取和制作贴片机的元件库数据上, 程序制作好后需要在生产的 时候检验贴装出来的元件角度和极性是否正确, 占用了大量的设备生产时间, 进而降低了生 产效率、 提高了生产成本。 发明内容
鉴于以上所述现有技术的缺点, 本发明的目的在于提供一种 SMT 设备快速制程系统及 方法, 用于解决现有技术中的 SMT 设备制程系统需要花费大量时间制作元件库数据及贴装 元件角度人工纠正而导致生产制程效率低以及极性错误而造成的产品良率低等问题。

在本实施例中, 所述搜寻单元 122搜寻与各该待贴片元件相匹配的元件资料时, 首先依 据所述文本数据到所述本地资料库 121 中搜寻与各该待贴片元件相匹配的元件属性是否存 在, 若是, 则将搜到的元件资料与其对应的待贴片元件相关联, 并将该元件资料标记为可用 元件, 若否, 然后在依据所述图形数据到所述本地资料库 121中搜寻与各该待贴片元件相匹 配的图形信息是否存在, 若是, 则将搜到的元件资料与其对应的待贴片元件数据相关联, 并 将该元件资料标记为可用元件。

具体地, 首先进行角度和坐标偏移的智能校正, 即, 先将 0度的元件资料的图形模拟放 到核心数据的图形上, 计算元件资料图形区域内包含的核心数据的图形内的焊盘的面积, 再 将 90 度的元件资料图形模拟放到系统核心数据的图形上, 计算元件资料图形区域内包含的 核心数据的图形内的焊盘的面积, 再根据元件资料是否存在极性点判断是否有极性, 如果没 有比较 0度和 90度的图形包含的面积, 最大者为最后的正确的角度, 将角度偏移存下来。 如果有极性, 先不做比较, 再将 180度的元件资料图形模拟放到系统核心数据的图形上, 计 算元件资料图形区域内包含的核心数据的图形内的焊盘的面积, 再将 270度的元件资料图形 模拟放到系统核心数据的图形上, 计算元件资料图形区域内包含的核心数据图形内的焊盘的 面积, 选取面积最大并且极性标记位置最接近的。
然后, 按顺序对元件资料定义的所述本地资料库 121中标记为可用元件的元件资料和核 心图形的校验匹配。 1.判断是否存在同时无外形和封装的元件。 2.是否无外形。 3.是否无供 料器封装信息。 4.外形与核心图形的中心是否一致。 5.角度和极性是否与核心图形不一致, 6. 引脚数量是否一致。 以上为有一个问题时就不进行下一步判断。 最后, 使用人工检查模块, 针对出现的问题进行相应的修改元件资料, 修改结束再进行自动校验, 直至修改没有问题为 止。

在本实施例中, 所述元件共享资料库 3例如为通过广域网或局域网与 SMT设备系统 2 相连的服务器, 也可以是内置在所述 SMT设备快速制程系统 1中的另一资料库。
在步骤 S2中, 读取输入的 PCB设计文件及 BOM文件, 并生成包含有所有待贴片元件 的文本数据及图形数据的核心数据, 在本实施例中, 读取输入的 PCB设计文件包括 CAD文 件和 Gerber文件以及对应所述 Gerber文件的坐标文件; 所述文本数据包括元件编码、 元件 描述、 元件外形名、 以及元件高度; 所述图形数据包括元件外框尺寸、 元件引脚尺寸、 引脚 数量、 引脚间距、 极性点标识、 以及第一引脚位置。 接着执行步骤 S3。
在步骤 S3 中, 读取所述核心数据, 依据所述核心数据到所述本地资料库中搜寻与各该 待贴片元件相匹配的元件资料, 将搜到的元件资料与其对应的待贴片元件相关联, 并将该元 件资料标记为可用元件, 当在所述本地资料库中未搜寻与待贴片元件相匹配的元件资料时输 出创建元件资料的指令。 接着执行步骤 S4。
在本实施例中, 搜寻与各该待贴片元件相匹配的元件资料时, 首先依据所述文本数据到 所述本地资料库中搜寻与各该待贴片元件相匹配的元件属性是否存在, 若是, 则将搜到的元 件资料与其对应的待贴片元件相关联, 并将该元件资料标记为可用元件, 若否, 然后在依据 所述图形数据到所述本地资料库中搜寻与各该待贴片元件相匹配的图形信息是否存在, 若 是, 则将搜到的元件资料与其对应的待贴片元件数据相关联, 并将该元件资料标记为可用元 件。
具体地, 所述搜寻单元 122 搜寻与各该待贴片元件相匹配的元件资料时, 包含以下情 况: 1.将元件编码到本地资料库中进行搜寻完全相同的元件编码是否存在, 如果存在将这些 元件资料定义给它们并标记成功; 2.没有元件资料的元件再根据来自 CAD 或坐标内的元件 外形和 BOM 内的描述元件描述, 搜索出元件标准封装名, 再将本地资料库的元件资料定义 给它们并标记成功; 3. 没有元件资料的元件再根据系统核心图形数据匹配, 当元件大于 2 个引脚时, 搜索本地资料库的相同元件引脚数的元件, 并模拟将其放到图形上比对, 根据 IPC-7351的标准找寻最合适的进行推荐, 并定义。 当元件引脚小于等于 2时, 搜寻本地资料 库中没有引脚的元件资料, 根据元件本体的大小和 IPC-7351 的标准进行比对, 搜寻出合适 的元件资料并定义; 4. 再没有元件资料的元件输出提示信息提示操作者可以对本地资料库 进行手动搜寻, 搜寻支持元件本体长宽, 元件引脚数量, 元件引脚间距, 元件资料外形名 等。 根据经验判断合适的进行定义; 5. 再没有元件资料的元件可以通过复制现有的元件资 料再修改参数进行创建; 6. 再没有元件资料的元件可以通过创建元件资料模块进行创建。
在步骤 S4 中, 依据待贴片元件的核心数据创建元件资料, 将创建完成的元件资料存储 至所述本地资料库, 并将该元件资料标记为可用元件。 接着执行步骤 S5。
在本实施例中, 接收到所述创建元件资料的指令后, 首先判断 PCB 设计文件的格式, 当判断所述 PCB设计文件为 CAD文件时, 依据待贴片元件的核心数据创建元件资料; 当判 断所述 PCB设计文件为 Gerber文件时, 首先需要创建待贴片元件的焊盘信息, 再依据待贴 片元件的核心数据创建元件资料。
具体地, 核心数据内保留了数据来源的标记, Gerber文件来源需要选择焊盘创建, CAD 文件来源本身就有元件和焊盘的关联信息。 先确定元件的方向, 下一步自动提取元件外框尺 寸, 也可以修改, 再下一步选取引脚自动产生引脚信息, 引脚信息包括每个引脚的坐标和引 脚的尺寸, 如果含有矩阵引脚产生矩阵的信息, 再下一步根据元件本体大小推荐最合适的吸 嘴和供料器。 再下一步如果此元件有极性需要进行选取极性标记的图形和位置; 再下一步可 自行填写一些机器设备的参数, 比如元件贴装运行速度, 抛料位置等, 以上步骤可以将所有 的元件资料定义完毕, 并将新创建的元件资料存入到本地资料库中。
在步骤 S5 中, 校验所述本地资料库中标记为可用元件的元件资料, 并在校验出错误 时, 依据所述核心数据中的图形数据修复该记为可用元件的元件资料。 接着执行步骤 S6。
在本实施例中, 校验所述本地资料库中标记为可用元件的元件资料时, 首先验证该元件 资料中的元件外框尺寸、 元件引脚尺寸、 引脚数量、 引脚间距、 极性点标识、 以及第一引脚 位置是否与其核心数据相一致, 若是, 则通过校验, 若否, 则输出校验报错信息, 并依据所 述核心数据中的图形数据修复该记为可用元件的元件资料中的元件外框尺寸、 元件引脚尺 寸、 引脚数量、 引脚间距、 极性点标识、 以及第一引脚位置是与其核心数据相一致。
具体地, 首先进行角度和坐标偏移的智能校正, 即, 先将 0度的元件资料的图形模拟放 到核心数据的图形上, 计算元件资料图形区域内包含的核心数据的图形内的焊盘的面积, 再 将 90 度的元件资料图形模拟放到系统核心数据的图形上, 计算元件资料图形区域内包含的 核心数据的图形内的焊盘的面积, 再根据元件资料是否存在极性点判断是否有极性, 如果没 有比较 0度和 90度的图形包含的面积, 最大者为最后的正确的角度, 将角度偏移存下来。 如果有极性, 先不做比较, 再将 180度的元件资料图形模拟放到系统核心数据的图形上, 计 算元件资料图形区域内包含的核心数据的图形内的焊盘的面积, 再将 270度的元件资料图形 模拟放到系统核心数据的图形上, 计算元件资料图形区域内包含的核心数据图形内的焊盘的 面积, 选取面积最大并且极性标记位置最接近的。
然后, 按顺序对元件资料定义的所述本地资料库中标记为可用元件的元件资料和核心图 形的校验匹配。 1.判断是否存在同时无外形和封装的元件。 2.是否无外形。 3.是否无供料器 封装信息。 4.外形与核心图形的中心是否一致。 5.角度和极性是否与核心图形不一致, 6.引 脚数量是否一致。 以上为有一个问题时就不进行下一步判断。 最后, 使用人工检查模块, 针 对出现的问题进行相应的修改元件资料, 修改结束再进行自动校验, 直至修改没有问题为 止。
在步骤 S6中, 将校验通过的元件资料输出至该 SMT设备系统以令其进行 PCB贴片或 AOI检测作业。 于本实施例中, 将校验通过的元件资料输出至该 SMT设备系统的数据输出 方式有以下几种:
1) 如果 SMT设备系统有开放接口, 支持无缝集成关联输出, 则通过开放接口无缝关联 直接输出相关设备系统 JOB 数据。 例如 Fuji API接口, ASM/ Siplace OIB接口, 例如, 提 供的第三方数据输出方式, 输出通过校验的元件资料到的所述 SMT设备系统可以是 Fuji富 士设备提供的 API: User Host Interface , Siplace 设备提供的 API: OIB ( OPERATIONS INFORMATION BROKER )、 或者其他文本文件、 数据库等各种形式的设备接口。
2)也可以输出文本或其它形式中间数据再导入 SMT设备系统。
3) 也可以通过二者之间的合作嵌入式交互实现。
综上所述, 本发明的 SMT设备快速制程系统及方法, 解决了现有技术中的 SMT设备 制程系统需要花费大量时间制作元件库数据而导致生产效率低以及不能检验元件角度和极性 而造成的产品良率低等问题。 本发明的 SMT 设备快速制程系统及方法大幅縮短新机种整体 编程周期, 充分减少机器编程调试占用时间, 合理节省人力成本。 相比于目前行业方案, 具 有以下有益效果: 通过本发明 SMT 设备快速制程系统及方法的实施, 可以做到最大化利用 设计信息, 即实现了 100% 准确利用; 在智能基准点与板子信息获取时节省不小于 15 分 钟; 智能匹配及创建元件资料库时可以节省 80%时间, 在自动角度及极性校正时可节省 90%调试时间; 在无缝生成设备程序中可确保设备程序数据精确、 完整。 本发明的 SMT 设 备快速制程系统及方法将一个繁琐的工作变成简易防呆化, 将原来 8小时以上的工作縮短至 2小时内, 整体提高了 50%以上的效率。 所以, 本发明有效克服了现有技术中的种种缺点而 具高度产业利用价值。
