Description

智能弹簧制造系统 技术领域
本发明涉及弹簧制造技术领域，尤其涉及一种通过经验数据库的导入加快调校与试产速度的智能弹簧制造系统。
背景技术
常见的多轴线材折弯机(或称多轴弹簧机)可分两大类，一类称为卷簧机具有至少5轴以上的加工自由度，另一类称为万用机则加工自由度在10轴以上。上述多轴弹簧机多采用计算机数值控制(CNC)的方式来控制各轴的运动，基本上最常发生的困难有以下两种：
其一，应用计算机数值控制(CNC)控制工具机的方式主要用在加工坚硬的钢铁金属，其控制刀具预设的加工尺寸会与加工后成品的实际尺寸相同。但一般的弹簧线材多是弹性很好的钢材，在受力变形后会发生回弹的现象，而回弹大小的变量包含材质的不同、加工时间的长短或变形外力的大小，同一卷弹簧线材每段的材质又有差异，导致应用计算机数值控制的多轴弹簧机加工时，其刀具摆设若恰好符合预设制作弹簧成品的尺寸，也就是原始弹簧的尺寸，则成品的实际尺寸往往会与预设的尺寸产生很大的公差，此公差的主因来自于弹簧线材的回弹，需要较多的时间以试误的方式进行调校、试产才能生产出良好的弹簧成品。
其二，计算机数值控制(CNC)一般用于控制工具机加工制造时间长的工件，CNC计算机数值控制(CNC)的编程储存的目的在停电、停机复工时能再加载编程再继续生产，因此控制器的设计较少考虑多样少量的问题。而多轴弹簧机的工件加工时间短，经常转换生产不同尺寸的弹簧，且在制造不良品时最好能快速变更编程以进行校正，因此多轴弹簧机的控制与编程追求的方向是能快速设定与转变，现有的计算机数值控制(CNC)的控制方式不适合用于控制多轴弹簧机。
发明内容
现有的计算机数值控制(CNC)不适合用于控制多轴弹簧机，不能加快多轴 弹簧机生产制造不同规格弹簧时的调校时间。为此，本发明的目的在于通过适当参数制成的经验数据库修正工业计算机的编程，达到首次制造就能产出接近原设定尺寸的弹簧，由此加快多轴弹簧机的生产。
为达到上述目的，本发明提供一种智能弹簧制造系统，包括：
一多轴弹簧机；以及
一与该多轴弹簧机电连接的工业计算机，该工业计算机设有一控制接口，该控制接口接收用户输入线材材质、线材截面外型与尺寸以及弹簧型式、弹簧规格的数据，在该工业计算机储存多个经验数据库，各经验数据库分别对应一种弹簧型式、一种线材材质与一种线材截面外型与尺寸，将各经验数据库储存为横、纵两轴分别为弹簧指数与节距角度的矩阵表，在各经验数据库内记载多个经验校正系数，各经验数据库分别对应一种弹簧型式、一种线材材质与一种线材截面外型与尺寸；
该工业计算机接收由该控制接口输入的该弹簧型式与该弹簧规格的数据，依数理逻辑产生一原始控制程序，该原始控制程序包括多个依照时间轴排列的步骤，各步骤包括多个控制该多轴弹簧机的控件目数据；该工业计算机选择一个对应由该控制接口输入的弹簧型式、线材材质以及线材截面外型与尺寸的经验数据库，依据由该控制接口输入的该弹簧规格、该线材截面尺寸计算出的弹簧指数与节距角度在该选择的经验数据库中查表，选择最接近或相同于该弹簧指数与该节距角度的经验校正系数，以该经验校正系数校正该原始控制程序中对应步骤的控件目数据而产生一校正控制程序，以该校正控制过程控制该多轴弹簧机生产一校正弹簧。
进一步，本发明所述的弹簧规格的数据包括圈数、外径以及长度；所述的控件目数据是该多轴弹簧机的多个运动轴在各所述的步骤中移动距离的控件目，包含所述的弹簧绕行的圈数、该弹簧的外径、节距、送线长以及时间。
较佳的，本发明所述的多轴弹簧机设有一机体；设有一影像检测装置，是在该机体的前面设有一摄影机，该摄影机拍摄该校正弹簧；所述的工业计算机与该摄影机电连接；在每一个校正弹簧制造完成受剪断之前，以该摄影机拍摄该校正弹簧并量测得出一实际尺寸，将实际尺寸与所述的弹簧规格的数据比对，若两者正负误差小于公差范围则判定合格，反之则判定不合格，当该多轴弹簧机连续制造不合格的校正弹簧的数量达到一设定误差数量时， 该工业计算机命令该多轴弹簧机停机并执行一校正的程序，校正该经验校正系数并将该校正后的经验校正系数回存至该经验数据库的对应位置，完成校正后再继续原来的生产直至完成良品数量。
较佳的，本发明在所述的多轴弹簧机的前方设有一弹簧分拣器，在该弹簧分拣器的下半部设有一成品部以及一废料部，在该弹簧分拣器的上半部设有一承接斗，以该承接斗承接该多轴弹簧机制造完成的校正弹簧，在该弹簧分拣器的中间设有一电控阀门，该电控阀门与该承接斗的底端相通，该电控阀门可选择性的与该成品部或该废料部相通；所述的工业计算机与该电控阀门电连接，当判定合格的校正弹簧落至该承接斗时，该工业计算机控制该电控阀门使合格的校正弹簧落入该成品部，当判定不合格的校正弹簧落至该承接斗时，该工业计算机控制该电控阀门使不合格的校正弹簧落入该废料部。
较佳的，本发明所述的影像检测装置在所述的机体的前面结合一光源，该光源朝所述的摄影机的方向照射，且所述的校正弹簧位于该光源与该摄影机之间。
本发明的多轴弹簧机制造弹簧时，通过工业计算机的控制接口接收用户输入线材特性的参数，也就是线材材质、线材截面外型与尺寸，以及该弹簧型式、弹簧规格的数据来产生一原始控制程序，并通过向对应一种线材特性的经验数据库查表的方式得出适用的经验校正系数，接着利用经验校正系数校正原始控制程序中对应控制该多轴弹簧机的步骤而产生所述的校正控制程序，通过该校正控制程序令该多轴弹簧机制造出接近或与原设定尺寸弹簧相同尺寸的校正弹簧。
本发明具有的优点在于：
本发明通过在同样或同类型的多轴弹簧机上经验的校正经验制作各经验数据库，在该多轴弹簧机更换制造弹簧的尺寸时，能快速地经由查表的方式获得校正原始控制程序的经验校正系数，并以经验校正系数校正原始控制程序得出校正控制程序，使多轴弹簧机开始转换生产不同的弹簧时，就能制造出与原设定尺寸相同或相近的校正弹簧，如此一来经由较少的尝试与较少的时间就能制造出与原设定尺寸相同的弹簧，可大幅缩短多轴弹簧机校正的时间，尤其适用少量多样的弹簧生产模式；若在多个多轴弹簧机之间交流经验数据库，还能同时加快多个多轴弹簧机生产制造时的校正过程。
再者，由于不同线材的回弹特性取决于多种不同的条件，各种线材条件的交集种类繁多。发明人选用了线材材质、线材截面外型与尺寸这两种与弹簧回弹程度最为相关的参数以及弹簧型式作为对应经验数据库的参数，可大幅简化该工业计算机需要储存的经验数据库的数量，减少制表以及工业计算机查表的负担。

具体实施方式
为能详细了解本发明的技术特征及实用功效，并可依照说明书的内容来实施，进一步以如图式所示的较佳实施例，详细说明如下。
如图1至图3所示的较佳实施例，本发明是一种智能弹簧制造系统，包括一多轴弹簧机10、一安装在该多轴弹簧机10的影像检测装置20、一设置在该多轴弹簧机10前的弹簧分拣器30，以及一分别与该多轴弹簧机10、该影像检测装置20以及该弹簧分拣器30电连接而控制该多轴弹簧机10、该影像检测装置20以及该弹簧分拣器30的工业计算机40，其中：
该多轴弹簧机10设有一机体11，在该机体11的前面设有一刀钻12，该刀钻12受一刀钻升降构造121驱动升降，对应刀钻12的正上方，在该机体11的前面设有一切刀机构122，在切刀机构122底端设有一受该切刀机构122驱动而朝下伸出的切刀123，该切刀123与该刀钻12左右交错，当该切刀123向下伸出时，会与该刀钻12交错产生剪断的效果。对应刀钻12左右两侧的其中一侧，在机体11前面设有一送线构造13，该送线构造13设有两上下相对且相向旋转的滚轮131，该送线构造13通过两滚轮131以抽拉的方式向该刀钻12的方向输出一弹簧线材A，该弹簧线材A的外端由一起弯点B开始卷绕成圆环状的弹簧C，该弹簧C悬挂在该刀钻12，该弹簧C的中心设为一虚拟圆心D，当弹簧C制造完毕时该切刀机构122驱动切刀123下伸，以切刀123配合该刀钻12将完成的弹簧C剪断，使弹簧C由多轴弹簧机10向前喷出而脱离弹簧线材A卷绕成圆圈处的末端。
对应该刀钻12的另一侧位置，在该机体11的前面设有一上下升降移动的装设座14，该装设座14受一刀具升降装置141驱动升降，该刀具升降装置141设于该装设座14与该机体11之间，以弹簧线材A的延伸线为上下的分界，在该装设座14前面的上下两侧设有两刀具位置控制装置15，各刀具位置控制装置15是斜向的设置，且各刀具位置控制装置15的延伸方向通过虚拟圆心D，在各刀具位置控制装置15朝向虚拟圆心的一端设有一弹簧外径刀151，两弹簧外径刀151分别抵靠该弹簧C，且两弹簧外径刀151的外端指向虚拟 圆心D。
当弹簧线材A受送线构造13输送时会依序抵靠下侧的弹簧外径刀151以及上侧的弹簧外径刀151而扭曲卷绕成圆环状的弹簧C，在该机体11结合一伺服马达16，该伺服马达16通过一装设在该机体11的动力传输装置161，例如皮带组、齿轮组、链条组、或一连杆组或上述举例的组合，搭配成一伺服驱动组162，该伺服驱动组162以同步且同行程的方式驱动该刀具升降装置141以及两刀具位置控制装置15，使该装设座14以及各弹簧外径刀151线性地同步且同行程移动，该刀具升降装置141以及刀具位置控制装置15可分别为螺杆组、凸轮组、齿轮组或上述举例的机械构造，能将装设座14及各弹簧外径刀151线性地移动。
多轴弹簧机10在该机体11对应该刀钻12上方朝向该送线构造13的一侧设有一节距刀位置调整器17，在该节距刀位置调整器17结合一节距刀171，该节距刀位置调整器17可驱动该节距刀171前、后进退移动，该节距刀171的外端伸入悬挂在刀钻12上的弹簧C的一侧，以该节距刀171的外端接触并导引卷绕的弹簧C向前螺旋伸长。例如以该多轴弹簧机10制造直筒型的该弹簧C时，是先等待该弹簧C绕完首圈之后，该节距刀位置调整器17驱动该节距刀171进行升节距的程序而由原点前进至定点，接着节距刀171固定位置使弹簧C绕行平行圈而前后变长，然后该节距刀位置调整器17驱动该节距刀171进行降节距的程序退回原点，等待该弹簧C绕行尾圈，即完成该节距刀171配合制造该弹簧C的过程，最后该切刀机构122驱动切刀123下伸，以该切刀123配合该刀钻12将完成的弹簧C剪断即可得到该弹簧C的成品；该节距刀171往前移动的位置可以控制该弹簧C成品的长度。
该影像检测装置20是在该机体11的前面设有一摄影机21，该摄影机位于该切刀机构122旁，且该摄影机21与该工业计算机40电连接，该摄影机21拍摄弹簧C的外型，在该机体11的前面结合一光源22，该光源22朝该摄影机21的方向照射，且该弹簧C位于该光源22与该摄影机21之间。
该弹簧分拣器30设置在该多轴弹簧机10的前方，在该弹簧分拣器30下半部的两侧设有一成品部31以及一废料部32，在该弹簧分拣器30的上半部设有一承接斗33，该承接斗33用以承接该多轴弹簧机10制造完成而向前喷出的弹簧C，在该弹簧分拣器30的中间设有一与该承接斗33底端相通的电 控阀门34，该电控阀门34可选择性的与该成品部31或废料部32相通。
该工业计算机40与该多轴弹簧机10电连接，以该工业计算机40控制该刀钻12的升降、该切刀123的动作，两滚轮131的转速、装设座14的升降、两弹簧外径刀151的位置，以及该节距刀171的位置。该工业计算机40控制装设座14的升降以及两弹簧外径刀151朝虚拟圆心D线性进退的距离是通过控制伺服驱动组162驱动该刀具升降装置141以及各刀具位置控制装置15的方式完成。该工业计算机40与该影像检测装置20的摄影机21电连接，接收该摄影机21拍摄的弹簧C的影像；该工业计算机40与该弹簧分拣器30的电控阀门34电连接而控制该电控阀门34。
请参看图1与图4所示，该工业计算机40设有一控制接口50，该控制接口50接收用户输入弹簧型式52以及弹簧规格51的数据，如本较佳实施例的弹簧型式52是由直筒型、橄榄型、漏斗型、锥型中选择制造直筒型的弹簧C，其弹簧规格51包括弹簧C的圈数、外径以及长度，对应一种弹簧型式52与弹簧规格51的数据产生一原始控制程序，当该原始控制程序供该工业计算机40执行时，可控制该多轴弹簧机10生产没有校正回弹尺寸的原始弹簧C。请参看图5所示，该原始控制程序包含多个依照时间轴排列的步骤，以及对应各步骤的多个控件目数据，多个控件目数据是该多轴弹簧机10的多个运动轴在各步骤中移动距离的控件目，包含圈数、外径、节距、送线长以及时间，其中圈数是弹簧C绕行的圈数，外径是弹簧C的外径尺寸、节距是控制节距刀171由上一步骤往下一步骤时所进或退的距离、送线长是该送线构造13于所在步骤时输送该弹簧线材A的长度、时间是各步骤所需要的时间，上述控件目数据有关长度的单位是mm，各步骤所需要的时间与该弹簧线材A的送线速度有关，送件速度越快则各步骤所需要的时间越短。
由于一般的弹簧线材A是弹性很好的材料，因此受力变形后会发生回弹的现象，而回弹的程度大小与弹簧线材A的多种条件有关，例如环境温度、材质、直径、截面外型，弹簧类别、弹簧外径、弹簧圈数、生产速度等等条件会对该弹簧线材A受力变形后回弹的程度产生影响，所以节距角度变大时，此参数值也变大，再加上节距刀的位置固定不变，而弹簧外径不同时，弹簧圈受节距刀推动的位置不同，所以弹簧指数变大，外径变大，此参数值也要变大，使得工业计算机40执行原始控制过程控制该多轴弹簧机10制造原始 弹簧C时，原始弹簧C成品的外径或长度的实际尺寸产生差异，这时就需要进行校正，将该原始控制程序的控件目数据，例如外径或节距的控件目数据，校正为制造外径或长度较小(缩小弹簧每一圈距离的节距)的弹簧C的数据成为校正后的校正控制程序，以校正控制过程控制该多轴弹簧机10制造出一校正弹簧C，该校正弹簧C在回弹后符合原设定尺寸的大小。
本发明为了避免该多轴弹簧机10在更换制造不同尺寸的弹簧C时，在调校该多轴弹簧机10制造出校正弹簧C上花费大量时间，因此在该工业计算机40导入用以校正该原始控制程序的经验数据库，在各经验数据库内记载各种不同尺寸弹簧C的经验校正系数，利用该经验校正系数校正该原始控制程序中选定的控件目数据，将该原始控制程序校正为校正控制程序。由于各种弹簧线材A回弹的程度不同，以及因外径大小不同使得节距刀对弹簧圈推动的位置不同，因此由多种与弹簧线材A回弹有关的条件中，选出线材材质、线材截面外型与尺寸的两种参数作为与弹簧线材A的回弹程度最为相关的条件，定义各经验数据库分别对应一种弹簧型式52、一种线材材质以及一种线材截面外型与尺寸。当该多轴弹簧机10用于生产制造同一种弹簧型式52的弹簧C的线材材质以及线材截面外型与尺寸各有三种时，就会需要使用多种经验数据库，将所需要的各经验数据库储存在该工业计算机40。
请参看图6所示的经验数据库，为了将相同弹簧型式52，不同弹簧规格51的弹簧C的经验校正系数都记载在经验数据库中(同一经验数据库中所用的弹簧C都是相同的弹簧型式52，并且以相同的线材材质以及线材截面外型与尺寸的弹簧线材A所制造)，选用可体现出特定弹簧规格51的弹簧指数(Spring index)以及节距角度(Pitch angle)的两个参数的数值(弹簧指数与节距角度是由已知的弹簧规格51以及线材截面尺寸，即线材直径计算得出)作为横轴以及纵轴的数据，将各经验数据库制作成一种矩阵表的数据型式储存。只要弹簧线材A的线材材质、线材截面外型与尺寸以及要生产出的弹簧C的弹簧型式52确定，就能在对应的经验数据库中以弹簧规格51查找出最接近或相同于该弹簧C尺寸的经验校正系数。上述各经验数据库内记载的多个经验校正系数，是由操作多轴弹簧机10的操作者，在同一种多轴弹簧机10以同样的线材材质、线材截面外型与尺寸的弹簧线材A开始制造各种相同弹簧型式52但不同弹簧规格51的弹簧C时，校正后的校正控制程序中的控件 目数据，例如选自外径与节距的控件目数据，除以原始控制程序中对应的控件目数据所得出的数值，即为所述的经验校正系数。
请配合参看图4至图7，以下通过校正该多轴弹簧机10制造出的弹簧C的长度(节距)为范例，说明通过本发明在经验数据库中查表得出一经验校正系数后，针对原始控制程序中的控件目数据例如节距，将原始控制程序的节距的数据校正、改写为校正控制程序的系统：
请参看图1、图2以及图4所示，该工业计算机40的该控制接口50接收用户输入，使用者采用线材材质为高碳钢(HI CARBON)且线材截面外型与尺寸各为圆形与直径0.8mm的弹簧线材A，制造弹簧型式52为直筒型且弹簧规格51为圈数6、外径6.5mm且长度10mm的弹簧C。如图5所示，该工业计算机40接收弹簧型式52为直筒型且圈数6、外径6.5mm且长度10mm的弹簧规格51产生一原始控制程序，该原始控制程序包括6个依照时间轴排列的步骤，以各步骤的程控该多轴弹簧机10进行生产，6个步骤的步骤名称依序为切刀、首圈、升节距、平行圈、降节距以及尾圈。
切刀步骤是控制该多轴弹簧机10以该切刀123配合该刀钻12将完成的弹簧C剪断，首圈步骤是绕完1圈的该弹簧C首圈，升节距步骤是控制该多轴弹簧机10驱动该节距刀171由原点前进1.704mm的位置并且过程中绕完1圈的弹簧C，平行圈步骤是固定该节距刀171的位置绕行2.75圈的弹簧C，降节距步骤是控制该多轴弹簧机10驱动该节距刀171由所在的位置后退1.704mm的位置退回原点并且过程中绕完1圈的弹簧C，最后的尾圈步骤是绕完0.25圈的弹簧C尾圈；上述各步骤的外径都保持为6.5mm。上述的原始控制程序的6个步骤是用于控制该多轴弹簧机10制造出一回弹后尺寸与原设定尺寸会产生误差的原始弹簧C，因此还需要进行校正。
请参看图6，该工业计算机40选择一对应线材材质为高碳钢、线材截面外型与尺寸各为圆形与直径0.8mm，以及弹簧形式52为直筒型的经验数据库，由已知的弹簧C的线材截面尺寸，即线材直径0.8mm以及弹簧的外径6.5mm、长度10mm的数据计算出弹簧指数以及节距角度分别为7.1以及5.5，经由查表得出最接近该弹簧规格51的经验校正系数是X、Y坐标为7.0、5.5的0.82，以0.82乘以该原始控制程序对应节距的控件目数据，即乘以节距的数据，将升节距步骤以及降节距步骤的节距的数据1.704以及-1.704校正、改写为1.397 以及-1.397，从而得出一校正控制程序工提供该多轴弹簧机10执行以制造一校正弹簧C，该校正弹簧C回弹后尺寸的弹簧指数与节距角度相当于7.0以及5.5。
由于该校正弹簧C是利用该工业计算机40读取曾经制造出接近或与原设定尺寸一致的弹簧的校正控制程序所制造，因此制造出的校正弹簧C很接近或与原设计尺寸一致，因此执行该校正控制程序后，不需要经过太多时间以及尝试，就能使该多轴弹簧机10制造出与原设计尺寸相符的弹簧C，大幅降低该多轴弹簧机10更换生产不同尺寸弹簧C时所需要的校正时间。
本发明的工业计算机40执行校正控制过程控制该多轴弹簧机10制造校正弹簧C，除了能够以人工的方式量测制造出的校正弹簧C是否合乎尺寸，由此对该校正控制程序进行再度的校正，来制造出与原设定尺寸相符的弹簧C以外，也能够以自动化的方式检测校正弹簧C的尺寸来校正该校正控制程序，说明如下：
在每一个校正弹簧C制造完成并受切刀123配合刀钻12剪断之前，以影像检测装置20的摄影机21拍摄该校正弹簧C并量测该校正弹簧C的长度得出一实际尺寸，将实际尺寸与该校正弹簧C的原设定尺寸，即弹簧规格51的尺寸比对，若该实际尺寸与原设定尺寸的正负误差小于公差范围则判定合格，当合格的校正弹簧C被剪断并喷出至弹簧分拣器30时，该工业计算机40控制电控阀门34使合格的校正弹簧C落入成品部31。
当将实际尺寸与该校正弹簧C的原设定尺寸比对，若实际尺寸与原设定尺寸的正负误差大于公差范围则判定不合格，当不合格的校正弹簧C被剪断并喷出至弹簧分拣器30时，该工业计算机40控制电控阀门34使不合格的校正弹簧C落入废料部32收集。当该多轴弹簧机10连续制造不合格的校正弹簧C的数量达到一设定误差数量，例如连续制造三次不合格的校正弹簧C时，该工业计算机40命令该多轴弹簧机10停机并执行一校正的程序，例如校正该校正控制程序的控件目数据，例如节距的数据并改写该校正控制程序，以校正的校正控制程序供该工业计算机40执行，并将可计算得出该校正后的控件目数据的经验校正系数写回对应的经验数据库内；上述的设定误差数量可以是二以上的任意数量。
例如该多轴弹簧机10停机前，该工业计算机40最后以摄影机21拍摄并 量测的三个不合格的校正弹簧C的数值都大于10mm+公差值，表示该原始控制程序所算出的节距1.704mm，因无法考虑节距刀的位置与线材回弹系数而过大，通过由该经验数据库取一经验校正系数0.820后，将原始控制程序所算出的节距改为1.704mm*0.820＝1.397mm，以此校正后的校正控制过程控制该多轴弹簧机10进行制造，若该校正后的校正控制程序可控制该多轴弹簧机10制造出符合原设定尺寸的弹簧C，即将校正后的节距数值定为1.397mm，除以原设定尺寸的节距数值得出校正后的经验校正系数0.820，并将该校正后的经验校正系数写回对应的经验数据库，完善该经验数据库供该工业计算机40使用。若该多轴弹簧机10制造弹簧C的过程中再有连续制造不合格的弹簧C达到该设定误差数量时，该工业计算机40命令该多轴弹簧机10停机，再度重复上述校正程序。该工业计算机40内储存的多个经验数据库除了供给本身使用以外，也可以转移给其他的多轴弹簧机10的工业计算机40使用。
以上所述仅为本发明的较佳实施例而已，并非用以限定本发明主张的权利范围，凡其它未脱离本发明所揭示的精神所完成的等效改变或修饰，均应包括在本发明的申请专利范围内。
