Description

缓冲材输送卷绕设备、缓冲材输送方法及模组绑定*** 技术领域
本申请属于玻璃覆晶技术领域，更具体地说，是涉及一种用于缓冲材输送卷绕设备、缓冲材输送方法及具有该缓冲材输送卷绕设备的模组绑定***。
 背景技术
在COG（chip on glass，玻璃覆晶）本压工艺中，需要一定压力和高温将芯片绑定在玻璃屏上，因为玻璃屏的易脆裂特性，在绑定操作时，需要使用缓冲材。缓冲材被置于本压头和芯片线路板之间，利用本压头将芯片线路板固定于玻璃屏上，缓冲材起缓冲和导热均匀的作用。
由于缓冲材的使用寿命有限，因此压合几次后，就需要更换缓冲材。目前缓冲材输送卷绕设备把缓冲材的两端分别卷绕在供料辊和回收辊上，通过旋转供料辊和回收辊将已使用过的缓冲材移走，同时将将未受压合的缓冲材移动到玻璃屏上再作业。现有技术中通过控制供料伺服马达单次转动实现缓冲材每次进给的输送长度，这个供料伺服马达单次转动时缓冲材的输送长度称作供给长度（也称为模拟长度）。这种方案存在不足，因为供料辊和回收辊的卷绕松紧程度不同或者卷绕在供料辊上的缓冲材直径不断减小，通过控制供料伺服马达来控制缓冲材供给长度会造成每次传送的缓冲材存在误差，就可能出现重复压着的风险或者浪费缓冲材。
 技术问题
本申请提供一种缓冲材输送卷绕设备、缓冲材输送方法及模组绑定***，以解决现有技术中存在的因供料伺服马达单次转动输送的缓冲材供给量可能存在误差而造成缓冲材重复压着的技术问题。

在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
请参阅图1和图2，现对本申请提供的缓冲材输送卷绕设备进行说明。缓冲材输送卷绕设备包括：机架、供料辊1、供料伺服马达、回收辊2、回收扭矩马达、测量装置、控制器和报警器。其中，供料辊1、供料伺服马达、回收辊2、回收扭矩马达都固设在机架上。
供料辊1用于输送缓冲材5，缓冲材3未被使用过的部分卷绕在供料辊1上。
供料伺服马达，受控制器控制用于为供料辊1提供单次转动旋转动力。
回收辊2，用于回收所述缓冲材，缓冲材5被使用过的部分卷绕在回收辊2上。
回收扭矩马达，用于为回收辊2提供旋转动力，在整个缓冲材输送过程中始终处于工作状态，主要是带动回收辊2回收使用过的缓冲材，并保持缓冲材张力，当缓冲材5在松弛状态时，回收扭矩马达就能够转动并带动回收辊2对缓冲材5进行卷绕回收，而且回收扭矩马达能够堵转，马达堵转就是在马达因外力不转动甚至反转时仍能够提供扭矩的状态。回收扭矩马达的扭矩设定值不大，当供料辊1不供料、缓冲材5处于紧绷状态时，因为供料伺服马达不转动而回收扭矩马达的扭矩设定值又比较小的原因，此时回收扭矩马达就处于不能转动的堵转状态，回收扭矩马达也就不能回收缓冲材5，如果供料伺服马达带动供料辊1反转，供料辊1会拉动缓冲材5继而带动回收辊2和回收扭矩马达反转，此时回收扭矩马达处于反转的堵转状态，这样回收辊2上回收的缓冲材5会被拉回。
测量装置3与机架相连，用于测量供料伺服马达单次转动供料时（同时也是回收扭矩马达单次转动回收缓冲材5时）回收辊2卷绕缓冲材5的实际回收长度，测量装置3可以是任意能够实现测算回收长度的各种装置，如ccd（电荷耦合元件）视觉检测装置等，在本申请实施例中不作特别限定。
控制器可以是常规的PLC（可编程控制器）、单片机或者计算机等控制装置，用于协调缓冲材输送卷绕设备的动作来配合COG（玻璃覆晶）本压操作，具体包括控制供料伺服马达单次转动输送缓冲材5、设定缓冲材5的供给长度及供给长度的尺寸公差、接受测量装置3的信号并监测缓冲材5的回收长度、判断回收长度与供给长度的差值是否符合尺寸公差、控制供料伺服马达正反转以及在异常操作时控制报警器报警等功能，其中测量装置3与控制器的输入端电连接，控制器的输出端分别与供料伺服马达和报警器电连接。
本申请实施例提供的缓冲材输送卷绕设备工作原理如下：先通过控制器设定供料伺服马达单次转动输送的缓冲材5的供给长度及供给长度的尺寸公差，并使回收扭矩马达始终处于回收工作状态；在需要移走使用过的缓冲材5时，供料伺服马达依照供给长度转动并输送未使用的缓冲材5，回收扭矩马达卷绕使用过的缓冲材5，同时测量装置测量回收扭矩马达卷绕缓冲材5的实际回收长度。
控制器判断回收长度与供给长度的差值是否符合供给长度的尺寸公差，若差值大于尺寸公差的上偏差或者小于尺寸公差的下偏差，则控制器控制报警器报警，操作者接到报警后查找供给长度与回收长度出现偏差的原因并进行调整或者维修；若差值处于尺寸公差的范围内，则等待下一动作循环。
此外，本申请实施例提供的缓冲材输送卷绕设备在判断回收长度与供给长度的差值是否符合供给长度的尺寸公差时还可以如下述方法工作：控制器判断回收长度与供给长度的差值是否符合供给长度的尺寸公差，若差值大于尺寸公差的上偏差，则控制器控制供料伺服马达反转，拉回多输送的缓冲材，此时回收扭矩马达也被拉动反转，直至控制器通过测量装置判断反转操作后的回收长度与供给长度的差值处于尺寸公差的范围内，然后供料伺服马达停止反转，等待下一动作循环。若差值小于尺寸公差的下偏差，则控制器控制供料伺服马达继续输送的缓冲材直至回收长度与供给长度的差值处于尺寸公差的范围内，然后供料伺服马达停止反转。若差值处于尺寸公差的范围内，则供料伺服马达不再动作，等待下一动作循环。
本申请提供的缓冲材输送卷绕设备，设置了用于检测单次转动时回收辊卷绕缓冲材的回收长度的测量装置、用于判断回收长度与供给长度是否符合要求的控制器及报警器，能够在回收长度与供给长度不符合要求时使报警器发出报警提示操作者，避免了已过使用寿命的缓冲材重复压着的风险及浪费缓冲材的问题。
在一个实施例中，请参阅图1和图2，作为本申请提供的缓冲材输送卷绕设备的一种具体实施方式，测量装置3包括编码轮32、编码器31和弹性固定结构。
编码轮32与卷绕在回收辊2上的缓冲材5的最外圈的始终保持弹性抵接，编码轮32与回收辊2的（旋转）轴向平行，编码轮32与回收辊2的旋转方向相反，编码轮32作为从动轮由缓冲材5提供旋转动力，缓冲材5回转长度与编码轮32旋转过的长度相等。
编码器31的转轴与编码轮32相连，编码器32与控制器的输入端相连，由卷绕在回收辊2上缓冲材5带动编码轮32转动并通过编码器31测量回收辊2单次转动时卷绕的缓冲材5的回收长度。弹性固定结构的结构类型不限，只要能实现编码轮32能够与卷绕在回收辊2上缓冲材5的最外圈保持弹性抵接的即可，弹性固定结构的一端固设与机架上，另一端与编码器31或者编码轮32弹性连接。在本实施例中的测量装置利用编码器和编码轮实现对缓冲材回收长度的测量，测量精准可靠而且制造成本非常低廉。
在一个实施例中，请参阅图1和图2，编码器31还设置了一个角钢形框架，编码器31固定在角钢形框架上，而编码轮32是与编码器31的转轴相连的，相当于编码轮32是铰接在角钢形框架上，弹性固定结构的一端固设与机架上，另一端与角钢形框架弹性连接。
在一个实施例中，编码器31为光电编码器，体积小，分辨率高。
在一个实施例中，编码器31为绝对型编码器，绝对型编码器的每一个位置绝对唯一，无需掉电记忆，不需要找参考点，抗干扰能力强。
在一个实施例中，请参阅图1和图2，弹性固定结构包括伸缩调整件34和弹性件33，固设在机架上伸缩调整件34的长度可调，能够实现操作者根据不同需求而调整编码轮32的伸出长度，进一步保证编码轮32始终与缓冲材5的最外圈弹性抵接。本实施例中的弹性件33结构类型不限，可以是拉簧、压簧、弹性橡胶等，其一端与伸缩调整件34相连，另一端与编码轮32或者编码器31相连。其中在本实施例中的伸缩调整件34结构类型不限，只要能实现长度可调即可，如可锁定的伸缩管等。
在一个实施例中，请参阅图1和图2，伸缩调整件34具体为气缸，气缸包括缸体和活塞杆。缸体固定在机架上，活塞杆与弹性件33相连。弹性固定结构还包括控制阀，用于初始调试时通过控制气缸调整编码轮32与回收辊2之间的距离，控制阀与气缸气连，控制阀与控制器的输出端电连，操作者可以通过口控制器来调整编码轮32使之与缓冲材5的最外层弹性抵接。
在一个实施例中，控制阀为电控伺服阀，电控伺服阀对气缸的控制更加精确，便于在控制过程中控制器对缓冲材的精确输送。
在一个实施例中，伸缩调整件34为包括设有内螺纹的套筒和与套筒螺纹连接的螺柱，套筒固定在机架上，螺柱与弹性件相连，操作者可通过旋转螺柱在初始调试时调整编码轮32使之与缓冲材5的最外层弹性抵接。
在一个实施例中，套筒的内螺纹为梯形螺纹，螺柱为梯形螺纹螺柱，梯形螺纹的螺距一般较大，能够使操作者迅速地对伸缩调整件34长度的进行调节。
在一个实施例中，套筒的内螺纹为矩形螺纹，螺柱为矩形螺纹螺柱，矩形螺纹螺的距一般较大，能够使操作者迅速地对伸缩调整件34长度的进行调节。
在一个实施例中，套筒和螺柱均为合金工具钢构件，合金工具钢材质的构件坚硬耐磨，套筒和螺柱的螺纹不易损坏。
在一个实施例中，套筒和螺柱均为经过调质处理的钢构件，钢构件坚硬耐磨，而且制造成本低廉。
在一个实施例中，作为本申请提供的缓冲材输送卷绕设备的一种具体实施方式，弹性件33为压簧，成本低。
在一个实施例中，压簧为矩形压簧，矩形压簧的截面为矩形，抗疲劳，耐使用。
在一个实施例中，作为本申请提供的缓冲材输送卷绕设备的一种具体实施方式，控制器为设有人机交互触摸屏的可编程控制器（PLC），成本低廉，操作简单，易于编程和交互。

在一个实施例中，作为本申请提供的缓冲材输送卷绕设备的一种具体实施方式，控制器为设有人机交互界面的单片机，成本低廉。
本申请的目的还在于提供一种缓冲材输送方法，用于在COG（玻璃覆晶）本压工艺中控制缓冲材的传递和回收，包括以下步骤，
S10:先通过控制器设定供料伺服马达单次转动输送的缓冲材5的供给长度及供给长度的尺寸公差，回收扭矩马达始终处于回收工作状态。
S20:在需要移走使用过的缓冲材5时，供料伺服马达依照供给长度转动并输送未使用的缓冲材5，回收扭矩马达卷绕使用过的缓冲材5，同时测量装置测量回收扭矩马达卷绕缓冲材5的回收长度。
S30:控制器判断回收长度与供给长度的差值是否符合供给长度的尺寸公差，若差值处于尺寸公差的范围内，则等待下一动作循环；若差值大于尺寸公差的上偏差或者小于尺寸公差的下偏差，则控制器控制报警器报警，操作者接到报警后查找供给长度与回收长度出现偏差的原因并进行调整或者维修。
本申请提供的缓冲材输送方法，通过监测缓冲材的实际回收长度，并判断回收长度与供给长度是否符合要求，能够在回收长度与供给长度不符合要求时报警提示操作者，避免了已过使用寿命的缓冲材重复压着的风险及浪费缓冲材的问题。
在一个实施例中，作为本申请提供的缓冲材输送方法的一种优化实施方式，在步骤S30中，控制器判断回收长度与供给长度的差值是否符合供给长度的尺寸公差，若差值大于尺寸公差的上偏差，则控制器控制供料伺服马达反转，拉回多输送的缓冲材，此时回收扭矩马达也被拉动反转，直至控制器通过测量装置判断反转操作后的回收长度与供给长度的差值处于尺寸公差的范围内，然后供料伺服马达停止反转，等待下一动作循环。
若差值小于尺寸公差的下偏差，则控制器控制供料伺服马达继续输送的缓冲材直至回收长度与供给长度的差值处于尺寸公差的范围内，然后供料伺服马达停止反转。若差值处于尺寸公差的范围内，则供料伺服马达不再动作，等待下一动作循环。在本实施中，控制器判断回收长度与供给长度的差值不符合尺寸公差范围，可报警给操作者警示，同时通过控制器控制供料伺服马达动作，实现回收长度的智能补偿，不但避免了已过使用寿命的缓冲材重复压着的风险及浪费缓冲材的问题，而且更加自动化，不影响本压压着操作，使本压压着操作更加连续。
这里应该指出的是当控制器判断回收长度与供给长度的差值不符合尺寸公差范围，报警给操作者是起警示的作用，告知操作者本次输送出现了异常，但设备本身还执行智能补偿，当然也可设置在控制器判断回收长度与供给长度的差值不符合尺寸公差范围时报警器并不报警，但此后续的回收长度补偿操作仍正常执行。
本申请的另一目的还在于提供一种模组绑定***，包括：上述的缓冲材输送卷绕设备、缓冲材5及本压头设备4，缓冲材5的一端卷绕在供料辊1上，另一端卷绕在所述回收辊2上，控制器与本压头设备电连接，协调缓冲材输送卷绕设备与本压头设备4的操作。

以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。

    其中，所述缸体固定在所述机架上，所述活塞杆与所述弹性件相连；
    所述弹性固定结构还包括控制阀，用于控制通过所述气缸调整所述编码轮与所述回收辊的间距，所述控制阀与所述气缸气连，所述控制阀与所述控制器的输出端电连接。
  18. 如权利要求13所述的缓冲材输送方法，其中，所述控制器为设有人机交互触摸屏的可编程控制器。
  19. 一种模组绑定***，包括：
    如权利要求1所述的缓冲材输送卷绕设备；
    缓冲材，所述缓冲材的一端卷绕在所述供料辊上，另一端卷绕在所述回收辊上；以及
    本压头设备，所述控制器与所述本压头设备电连接。
  20. 如权利要求19所述的模组绑定***，其中，所述测量装置，包括：
    编码轮，与卷绕在所述回收辊上的所述缓冲材的最外圈弹性抵接，所述编码轮由所述缓冲材提供旋转动力，所述编码轮与所述回收辊的轴向平行，且所述编码轮与所述回收辊的旋转方向相反；
    编码器，所述编码器的转轴与所述编码轮相连，所述编码器与所述控制器的输入端相连，由卷绕在所述回收辊上所述缓冲材带动所述编码轮转动并通过所述编码器来测量所述回收辊单次转动卷绕的所述缓冲材的回收长度；以及
    弹性固定结构，所述弹性固定结构的一端固设与所述机架上，所述弹性固定结构的另一端与所述编码器或者所述编码轮弹性连接，用于保持所述编码轮与卷绕在所述回收辊上所述缓冲材的最外圈弹性抵接。
