Description

一种导光膜产品加工设备 技术领域
本发明涉及导光膜加工领域，具体涉及一种导光膜产品加工设备。
背景技术
对着社会技术的发展，导光膜从配料至裁切成产品的多个工序逐渐形成一体化产业。在一体化生产过程中，基于对导光膜性能的要求，包括导光膜网点单元，现有的导光膜网点加工一般采用注塑成型或印刷等方式加工在导光板上，但传统的注塑成型或印刷等很难实现导光板的薄膜化设计，目前制备导光膜网点加工的方式逐渐趋向一体化设计，一步成型，简化制备流程，节约成本，因此一体成型导光膜网点加工方法是目前导光膜网点加工的优选方式。
现有技术中网点加工多为单面加工或分步实现导光膜双面网点加工，无法满足对导光膜性能逐步提高的社会需要。当然现有技术中，也存在装置改进以实现在导光膜双面一步成型网点，例如专利CN201010224529.3公开了一种导光膜制作装置，该装置采用压辊和版辊配合的方式实现在导光膜的待加工面上加工网点。虽然该方法可以实现膜表面网点的一步成型，但是由于膜运行配合辊转动的过程会存在步速差，因此压印网点时可能会对膜表面造成损伤。
另外，一体化生产过程中，在导光膜裁切为产品时，通常采用的是现将导光膜沿其传递方向切除多余的宽度，再进一步裁切成需要尺寸的产品，一个产线只能生产一种型号的导光膜产品，对于不同尺寸导光膜产品的生产，需要增设新产线，导致生产成本增加。
发明内容

现有技术中，一方面现有导光膜表面网点加工主要采用可绕辊轴转动的辊结构在导光膜表面转印网点，基于辊和导光膜可能存在的步速差，会造成对导 光膜表面损伤，另一方面，现有导光膜产品生产线的一般只能生产同一类型导光膜产品，无法在同一产线实现不同类型产品生产，进而使得企业增加生产成本。本申请旨在提出一种导光膜产品加工设备，同步在导光膜双面无损伤进行网点加工，在提高导光膜光学性能和质量的同时，生产不同类型的导光产品，并且生产效率高。
下面结合附图所示的实施例，对本发明的导光膜产品加工设备作进一步具体介绍。
结合图1所示，一种导光膜产品加工设备，包括放料装置1、网点加工装置3、冷却装置4、裁切装置5、废料收集装置6、产品收集装置8和联动控制器2。放料装置1用于放卷并传递第一导光膜9，第一导光膜9为未成型网点的导光膜；网点加工装置3、冷却装置4和裁切装置5沿第一导光膜9传递方向依次安装，网点加工装置3、冷却装置4和裁切装置5分别电连接于联动控制器2；网点加工装置3用于在第一导光膜9双面转印网点，冷却装置4用于冷却网点加工后的第一导光膜9，裁切装置5用于裁切冷却后的第一导光膜9获得导光膜产品；废料收集装置6用于收卷第二导光膜10，第二导光膜10为第一导光膜9裁切导光膜产品后的余料；产品收集装置8用于收集导光膜产品；定义第二导光膜10的收卷传递方向与第一导光膜9的传递方向构成的夹角为α，α＞0。
未成型网点的导光膜依次经过网点转印、冷却、裁切和分离，获得余料和产品，其中，附图所示的实施例中，直接将第一导光膜卷放置在放料装置1上，第一导光膜9由放料装置1向网点加工装置3传递，裁切后的第二导光膜10和产品在废料收集装置6的收卷力的作用下与导光膜产品分离，具体操作为调整第二导光膜10的收卷传递方向与第一导光膜9的传递方向之间的夹角大小，结构简单、操作方便。本实施例中，废料收集装置6对第二导光膜10的收卷方向与第一导光膜9的传递方向成90度夹角。
结合图2所示，网点加工装置3包括分别对称设置在第一导光膜9厚度方向的第一加压装置3.1和第二加压装置3.2、第一模具座3.3和第二模具座3.4、 第一热压模3.5和第二热压模3.6；第一模具座3.3安装于第一加压装置3.1靠近第一导光膜9侧，第一热压模3.5设置在第一模具座3.3靠近第一导光膜9侧，且第一热压模3.5平面平行于第一导光膜9表面；第二模具座3.4安装于第二加压装置3.2靠近第一导光膜9侧，第二热压模3.6设置在第二模具座3.4靠近第一导光膜9侧，且第二热压模3.6平面平行于第一导光膜9表面；第一模具座3.3和第二模具座3.4内部均设置有加热单元3.8，加热单元3.8用于加热软化第一导光膜9。
联动控制器2用于控制驱动第一加压装置3.1和第二加压装置3.2沿第一导光膜9厚度方向相对或相背运动，并且当第一加压装置3.1和第二加压装置3.2相对运动时，联动控制器2至少使得第一热压模3.5和第二热压模3.6抵触于第一导光膜9表面；即，当第一加压装置3.1和第二加压装置3.2相对运动，其中第一加压装置3.1带动第一模具座3.3及其上的第一热压模3.5挤压第一导光膜9一侧表面，第二加压装置3.2带动第二模具座3.4及其上的第二热压模3.6挤压第一导光膜9另一侧表面，第一热压模3.5和第二热压模3.6上的网点结构即转印在第一导光膜9表面上。为确保网点转印的效率，联动控制器2还用于程序控制第一模具座3.3和第二模具座3.4内部加热单元3.8的启停，加热单元3.8有助于导光膜9表面软化，便于第一热压模3.5和第二热压模3.6在导光膜表面成型网点。
一些实施例中，采用在第一加压装置3.1和第二加压装置3.2靠近第一导光膜9侧设置电连接于联动控制器2的距离传感器的方式，来阻停第一加压装置3.1和第二加压装置3.2的相对运动，达到控制网点转印而不损害导光膜9的效果。另外，为进一步提高本发明的应用范围，实施例将第一热压模3.5可拆卸连接于第一模具座3.3的凹槽3.7内壁，第二热压模3.6可拆卸连接于第二模具座3.4的凹槽3.7内壁；可拆卸式连接使得设备可以根据生产需要更换具有不同网点结构的热压模，节约成本，提高效率和减少开发周期等，例如，第一热压模3.5为镜面模、网点模或V结构模，第二热压模3.6为镜面模、网点模或V结构 模。当然第一热压模3.5和第二热压模3.6的结构远不止上述列出的结构，还可以根据生产要求自主设计网点结构。
结合图3所示，第一模具座3.3和第二模具座3.4结构相同；第一模具座3.3或第二模具座3.4靠近第一导光膜9侧均匀设置有位于同一直线的若干凹槽3.7，第一热压模3.5沿其厚度方向部分埋设于第一模具座3.3的凹槽3.7内，第二热压模3.6沿其厚度方向部分埋设于第二模具座3.4凹槽3.7内；加热单元3.8设置为电热单元，电热单元的传热平面平行于导光膜9表面，如电热片、由电热丝编制构成的电热结构等。
网点成型后，第一导光膜9继续向冷却装置4传递，冷却装置4实现网点转印后第一导光膜9表面固化。冷却装置4设置在网点加工装置3和裁切装置5之间，不影响第一导光膜9的传递，同时直接在第一导光膜9传递过程中实现膜即膜表面网点结构冷却定型，不影响产线的运行速度，减少网点加工时直接对膜冷却的耗时，提高导光膜产品的加工效率。
具体的，冷却装置4包括对称设置在第一导光膜9厚度方向的第一送风单元4.1和第二送风单元4.2、第一抽风单元4.3和第二抽风单元4.4；第一送风单元4.1包括开口朝向第一导光膜9的第一腔室、采用管道连接于第一腔室的送风机，第一抽风单元4.2包括开口朝向第一导光膜9的第二腔室、采用管道连接于第二腔室的抽风机；第二腔室设置在第一腔室内，且第二腔室开口所在的平面与第一导光膜9之间的距离不小于第一腔室开口所在的平面与第一导光膜9之间的距离；第二送风单元4.2包括开口朝向第一导光膜9的第三腔室、采用管道连接于第三腔室的送风机，第二抽风单元4.4包括开口朝向第一导光膜9的第四腔室、采用管道连接于第四腔室的抽风机；第四腔室设置在第三腔室内，且第四腔室开口所在的平面与第一导光膜9之间的距离不小于第三腔室开口所在的平面与第一导光膜9之间的距离。
实施例采用第一送风单元4.1和第二送风单元4.2实现对网点加工后第一导光膜9及膜表面网点的冷却定型，第一抽风单元4.3和第二抽风单元4.4实现将 第一导光膜9表面换热后的热空气抽走，加速网点加工后第一导光膜9的冷却，有利于网点成型，提高生产效率。
某些实施例中，进一步改进了冷却装置的送风单元和抽风单元，采用换热装置将经抽风单元抽走的热空气换热冷却后再传输到送风单元，实现空气在送风单元和抽风单元之间的循环利用。
进一步结合图2所示，裁切装置5包括与第三加压装置5.1、第三模具座5.2、裁切模具5.3和裁切平台5.4；第三加压装置5.1与第一加压装置3.1同侧安装，第三模具座5.2安装于第三加压装置5.1靠近第一导光膜9侧，裁切模具5.3可拆卸安装于第三模具座5.2靠近第一导光膜9侧；裁切平台5.4与第二加压装置3.2同侧安装，裁切平台5.3靠近第一导光膜9侧设置有传送平面平行于第一导光膜9的第一传送带5.5；第一传送带5.5沿第一导光膜9厚度方向与裁切模具5.3位置对应，并且第一传送带5.5靠近第一导光膜9的传送平面抵触于第一导光膜9。
其中，裁切模具5.3与第三模具座5.2可拆卸连接，有利于导光膜产品生产过程中即时暂停生产线，更换其它类型的裁切模具5.3，以便在同一产线获得不同尺寸、不同型号的导光膜产品。另外，采用第一传送带5.5在裁切平台5.4上传送第一导光膜9一方面可以在产品裁切后不掉落至裁切平台上，由第一传动带5.5传输至产品收集装置8，另一方面便于当在裁切模具5裁切第一导光膜9多次留有痕迹后更换，保护裁切平台5.4。
进一步的，为防止第一导光膜9传递至裁切装置5时发生偏差，导致裁切的导光膜产品不合格，第一热压膜3.5一侧边设置有若干向第一导光膜9侧凸起的标识网点，标识网点用于在第一导光膜9上印压标识；第三模具座5.2外壁与第一热压膜3.5设置标识网点的同侧设置有若干CCD定位相机5.6，CCD定位相机5.6的数量及位置与标识网点的数量及位置一一对应，一般不少于2个。CCD定位相机5.6电连接于联动控制器2，用于识别第一导光膜9上的标识，并生成一感应信号发送至联动控制器2；联动控制器2接收感应信号后，才控制启动裁 切装置5进行裁切。采用CCD定位相机5.6识别标识的方式可有效避免裁切装置5裁切不合格产品，提高导光膜产品的合格率。
部分实施例中，进一步采用CCD定位相机5.6识别标识的微调第一导光膜9传递至裁切装置5过程产生的偏移，具体为，设定CCD定位相机5.6的识别区域及第一导光膜9运行无偏离时标识位置，在第三模具座5.2靠近第一导光膜9侧设置有电连接于联动控制器2的连接部，连接部可拆卸连接于裁切模具5.3；定义第一导光膜9传递方向为前方，则连接部在第三模具座5.2上具有沿平行于第一导光膜9旋转的自由度，以及沿前、后、左、右平动的自由度；当CCD定位相机5.6识别到第一导光膜9上标识位置偏离设定的第一导光膜9运行无偏离时标识位置，生成一表示第一导光膜9偏离的感应信号并发送至联动控制器2，联动控制器2接收该感应信号后控制连接部带动裁切模具5.3向第一导光膜9偏离的方向微调位置，裁切装置5在裁切模具5.3位置微调后开始裁切导光膜产品，有效提高产品合格率。
进一步结合图1和图2所示，为确保导光膜产品加工质量，导光膜产品加工设备还包括各设置有两个导向轮的第一导向轮组11和第二导向轮组12，以及设置在裁切装置5和产品收集装置8之间的产品传送装置7。第一导向轮组11设置在放料装置1和网点加工装置3之间，第一导向轮组11的两个导向轮对称设置在第一导光膜9厚度方向的两侧，并且两个导向轮分别抵接于第一导光膜9的表面；第二导向轮组12设置在裁切装置5和产品传送装置7之间，第二导向轮组12的两个导向轮对称设置在第二导光膜10厚度方向的两侧，并且两个导向轮分别抵接于第二导光膜10的表面；产品传送装置7与第二导向轮组12间隔安装，产品传送装置7设置为传送平面平行于第一导光膜9的第二传送带，第二传送带与第一传送带5.5位于同一直线上，并且第二传送带靠近第一导光膜9的传送平面与第一传送带5.5靠近第一导光膜9的传送平面位于同一平面上；定义导光膜产品沿第一导光膜9传递方向的长度为d1，产品传送装置7与第二导向轮组12的安装间隔为d2，第二导向轮组12与第一传送带5.5的安装 间隔为d3，则d2＜1/2d1，d3＜1/2d1。
实施例设置两个导向轮组有利于第一导光膜9在网点加工装置3、冷却装置4和裁切装置5传递加工时表面的平整，产品上不产生褶皱，同时第二传送带与第一导向轮组11、第二导向轮组12间隔安装，主要目的在于传递收集与第二导光膜10分离后的导光膜产品。
为提高第一导光膜9网点加工效率，本发明将第一模具座3.3和第二模具座3.4均设置为大尺寸结构，即定义第一导光膜9的宽度为D，第一模具座3.3靠近第一导光膜9侧沿第一导光膜9宽度方向的宽度为D1，第二模具座3.4靠近第一导光膜9侧沿第一导光膜9宽度方向的宽度为D2，则D1＞D，D2＞D。第一模具座3.3和第二模具座3.4的尺寸设计，目的在于当第一加压装置3.1和第二加压装置3.2被驱动并带动第一模具座3.3和第二模具座3.4向第一导光膜9转印网点时可以一次性完成沿第一导光膜9宽度方向的网点成型，提高加工效率。另外，由于第一模具座3.3靠近第一导光膜9侧均匀设置有位于同一直线的若干凹槽3.7，因此在实际生产时可以根据实际待加工第一导光膜9的宽度，调整安装第一热压模3.5的数量，始终保证能一次性完成沿第一导光膜9宽度方向的网点成型，同时也适用于各宽度尺寸第一导光膜9的网点加工。
同理，为确保冷却装置4对第一导光膜9的冷却效率，即确保第一导光膜9表面全部能被送风单元加速换热，减少第一导光膜9表面降温不均对膜质量及性能的影响，冷却装置4设计如下：定义第一导光膜9的宽度为D，第一送风单元4.1的开口沿第一导光膜9宽度方向的宽度为D3，第二送风单元4.2的开口沿第一导光膜9宽度方向的宽度为D4，则D3＞D，D4＞D。
本发明的导光膜产品加工设备，设计合理，结构简单，可选用多种热压模中的任意两种，在第一导光膜表面转印网点，让导光膜产品两面达到不同的网点效果，光学性能大幅提升；同时，采用可更换裁切模具5.3的裁切装置5裁切不同类型导光膜产品，可避免对导光膜表面造成损伤，在不增加成本的条件下增加产品种类，并且有效提高产品的合格率，本发明的导光膜产品加工设备能 广泛应用于各个场合。
虽然本发明已以较佳实施例揭露如上，然其并非用以限定本发明。本发明所属技术领域中具有通常知识者，在不脱离本发明的精神和范围内，当可作各种的更动与润饰。因此，本发明的保护范围当视权利要求书所界定者为准。
