Description

一种金属化安全薄膜的屏蔽油移印装置及其移印方法 技术领域
本发明总体地属于金属镀膜技术领域，具体地涉及一种金属化安全薄膜的移印装置和方法。
背景技术
金属化薄膜现有的制作方法多采用真空移印的方法，其中，在基膜进行移印时，使用油屏蔽技术，即将屏蔽油按照花纹形状涂覆在基膜表面，使多个不相连的细小图案区域因为被屏蔽油覆盖而镀不上金属，比如金属块之间留有指定宽度的不被屏蔽油涂覆的直线，即可在金属块之间形成微小的保险丝，也就蒸镀出具有特定金属层形状结构的金属化安全薄膜。
目前，油屏蔽技术进行金属化薄膜移印中油量的控制主要是依靠油管温度的控制，如附图1所示，使用油屏蔽技术进行金属化薄膜移印的过程如下：将屏蔽油事先装到油管7内腔中，加热电阻8工作将油管7中的屏蔽油加热到需要温度，屏蔽油经过油管7的油管蒸发口9蒸发到陶瓷辊10的表面,陶瓷管10与花纹辊11直接接触并沿相反方向转动，因此将陶瓷辊10表面的屏蔽油转移到花纹辊11的接触面上，最后，将花纹辊11表面上的屏蔽油移印到基膜的表面，使不希望蒸镀金属层的基膜表面区域被印有屏蔽油，然后进行金属层蒸镀。在上述过程中，油管7中的屏蔽油的量随着蒸发出油管蒸发口9而逐渐减少，同等加热温度下经油管蒸发口9被蒸发出的油量也在逐渐变化，导致最后移印至基膜上的油量也逐渐变化，因此需要操作者通过人眼判定基膜上花纹的清晰度，不断调整加热电阻8来控制油管7内的屏蔽油温度，从而实现经油管蒸发口9被蒸发出的油量的调整，才能完成金属化安全膜的移印。可以看出，该技术方案完全依据人的经验进行经油管蒸发口9被蒸发出的油量控制，同时，伴随油管中屏蔽油在使用过程中量的减少和受温 度影响的老化，移印过程需要经常调整油管温度。
发明内容
本发明的目的在于克服现有技术中需要根据人工经验反复调整储存屏蔽油的油管的加热温度且油管中的油反复加热老化的缺陷，提供一种金属化安全薄膜的屏蔽油移印装置及利用其移印金属膜的方法，实现屏蔽油的外部储存、定量抽取、一次加热使用，进而保证金属化安全薄膜移印的可靠性和一致性。
本发明的一个方面，提供了一种金属化安全薄膜的屏蔽油移印装置，它包括储油罐、油泵、步进电机、油管、加热电阻、陶瓷辊、花纹辊、连接管和基膜驱动电机；所述储油罐用于储存常温下的屏蔽油；它通过连接管连接至油泵，油泵通过步进电机带动运转；所述油管包括油管进油口和油管蒸发口，油泵通过连接管连接至油管的油管进油口，加热电阻用于加热油管及泵经其内腔中的屏蔽油；所述陶瓷辊连接油管的油管蒸发口，所述花纹辊与所述陶瓷辊相互咬合并反向转动；待移印基膜与花纹辊的呈弧面接触，待移印基膜在基膜运行电机的驱动下运行，带动与之接触的花纹辊旋转，并使与花纹辊咬合的陶瓷辊相对于花纹辊反向转动。可以看出，本发明装置的工作过程为：油泵在步进电机带动下将储油罐中的屏蔽油经油管进油口送至油管内腔，屏蔽油被加热电阻加热通过油管蒸发口蒸发到陶瓷辊，基膜驱动电机带动待移印基膜运行，待移印基膜运行带动花纹辊转动，花纹辊转动导致陶瓷辊反向于花纹辊转动，从而从油管蒸发口蒸发到陶瓷辊的屏蔽油被转移至花纹辊，然后从花纹辊移印到待移印基膜上。
进一步的，步进电机带有微处理控制器，以控制步进电机的转速，所述步进电机的转速与所述油泵的转速相等；所述储油罐和油泵之间的连接管、以及油泵和油管之间的连接管为直径大小相等且直径为定值的硅胶管。
更进一步的，本发明装置还包括温控系统，用于控制加热电阻的加热温度。
本发明的另一方面，还提供了金属化安全薄膜的屏蔽油移印方法，它利用上述金属化安全薄膜的屏蔽油移印装置，包括以下步骤：
a)将屏蔽油储存于储油罐中；
b)根据待移印基膜的规格计算每万平方米的需油量，并根据待移印基膜的运行速度计算每万米需要的运行时间，从而获得待移印基膜每分钟需要的用油量；
c)同时，根据储油罐和油泵之间的连接管的直径计算油泵每转一圈的抽油量，由此通过步进电机的微处理控制器设定步进电机的速度；
d)按照步骤c)计算的步进电机速度启动步进电机运转，带动油泵将储油罐中的屏蔽油吸取出来经连接管和油管进油口送往油管；
e)启动加热电阻工作，使油管保持恒定的温度；
f)待油管的油管蒸发口有屏蔽油蒸汽喷出时，启动基膜驱动电机，待移印基膜运行带动花纹辊和陶瓷辊转动，从油管蒸发口喷出至陶瓷辊的屏蔽油被转移到花纹辊表面，花纹辊转动过程中将其上的花纹转移到与其接触的待移印基膜表面；
g)进行基膜的金属化蒸镀，基膜上带有屏蔽油的花纹部分没有被蒸镀上金属。
进一步的，上述步骤e)中油管保持的恒定温度高于泵入其中的屏蔽油的沸点。
进一步的，上述步骤d)中油泵向油管泵入屏蔽油的速度等于步骤f)中油管的油管蒸发口屏蔽油蒸汽喷出速度。
进一步的，上述基膜驱动电机驱动基膜匀速前进，带动花纹辊和陶瓷辊反向匀速转动。
进一步的，上述步骤f)中得到的待移印基膜表面上被转移的花纹以花纹辊的周长为周期重复。
本发明的目的在于实现屏蔽油的量化抽取和精准使用，降低人员操作依据经验判断的风险、避免屏蔽油反复加热老化对移印的影响。本发明装置通过微处理器对步进电机的转速进行准确控制，然后经机械传动装置对油泵产生推力，从而使得屏蔽油在推力作用下完成输送到油管内腔中，依靠油管中的加热电阻加热恒定温度，将屏蔽油蒸发转移到花纹辊上，然后移印到基膜上，即可实现油量的量化及精准控制。同时，屏蔽油储存在油管外的单独装置中，需要多少就抽取多少，避免屏蔽油一直存放在油管中反复加热老化的 问题。也不需要根据使用情况不时进行油管温度的调整，降低人员依据经验操作的风险，进而保证金属化安全薄膜蒸镀的可靠性和一致性。
本发明提供的方法结合实际待移印基膜的规格，计算单位时间的用油量，据此设定步进电机的速度，保证屏蔽油的定量持续供给，降低人员经验操作加热电阻加热温度带来的不利影响，同时根据具体的屏蔽油种类，确定加热电阻的加热温度，使进入油管中的油随时被蒸发出油管，避免油管中的油反复被加热，提高了基膜上屏蔽油层的质量和保护效果，保证了镀膜油量控制的可靠性和一致性。

为了使本领域技术人员更好地理解本发明，下面结合附图和具体实施方式对本发明作进一步详细说明。
实施例1
一种金属化安全薄膜的屏蔽油移印装置，其结构如图2所示，它包括储油罐1、油泵3、步进电机4、油管7、加热电阻8、陶瓷辊10、花纹辊11、连接管和基膜步进电机；所述储油罐1用于储存常温下的屏蔽油；它通过连接管连接至油泵3，油泵3通过步进电机4带动运转，步进电机4带有微处理控制器，用以控制步进电机4的转速，步进电机4的转速与所述油泵3的转速相等；所述油管7包括油管进油口6和油管蒸发口9，油泵3通过连接管连接至油管7的油管进油口6，加热电阻8用于加热油管7及泵经其内腔中的屏蔽油，优选的方案中，设置温控系统以用于控制加热电阻8的加热温度；所述陶瓷辊10连接油管7的油管蒸发口9，所述花纹辊11与所述陶瓷辊10相互咬合并反向转动；待移印基膜与花纹辊11的呈弧面接触，待移印 基膜在基膜运行电机的驱动下运行，带动与之接触的花纹辊11旋转，并使与花纹辊11咬合的陶瓷辊10相对于花纹辊反向转动，上述储油罐1和油泵3之间的连接管、以及油泵3和油管7之间的连接管优选直径大小相等且直径为定值的硅胶管。可以看出，本实施例装置的工作过程为：油泵3在步进电机4带动下将储油罐1中的屏蔽油经油管进油口6送至油管7内腔，屏蔽油被加热电阻8加热通过油管蒸发口9蒸发到陶瓷辊10；从油管7蒸发口喷出至陶瓷辊10的屏蔽油被转移到花纹辊11表面；基膜驱动电机带动待移印基膜运行带动，待移印基膜带动花纹辊11和陶瓷辊10转动，从油管蒸发口喷出至陶瓷辊10的屏蔽油被转移到花纹辊11表面，花纹辊11转动过程中将其上的花纹转移到与其接触的待移印基膜表面，待移印基膜上有屏蔽油的部分在后续蒸镀过程中镀不上金属。并且可以看出，因为待移印基膜不断运行带动花纹辊转动，两者的接触面相对于待移印基膜和花纹辊都在不断发生变化，当花纹辊转动一圈时，待移印基膜刚好也运行花纹辊11的一个圆周的长度，即将开始的接触面上的花纹与第一圈起始时的花纹相同，即待移印基膜表面上被转移的花纹以花纹辊11的周长为周期重复。
实施例2
一种金属化安全薄膜的屏蔽油移印方法，它利用实施例1的金属化安全薄膜的屏蔽油移印装置，包括以下步骤：
a)将屏蔽油储存于储油罐1中；
b)根据待移印基膜的规格计算每万平方米的需油量L，并根据待移印基膜的运行速度V)计算每万米需要的运行时间10000/V，从而获得待移印基膜每分钟需要的用油量LV/10000；
c)同时，根据储油罐1和油泵3之间的连接管的直径计算油泵3每转一圈的抽油量L1，由此通过步进电机4的微处理控制器设定步进电机4的速度V2＝LV/(10000L1)；
d)按照步骤c)计算的步进电机4速度启动步进电机运转，带动油泵3将储油罐1)中的屏蔽油吸取出来经连接管和油管进油口6送往油管7；
e)启动加热电阻8工作，使油管7保持恒定的、高于泵入其中的屏蔽油 沸点的温度；
f)待油管7的油管蒸发口9有屏蔽油蒸汽喷出时，启动基膜驱动电机，待移印基膜运行带动花纹辊11和陶瓷辊10转动，从油管蒸发口9喷出至陶瓷辊10的屏蔽油被转移到花纹辊11表面，花纹辊11转动过程中将其上的花纹转移到与其接触的待移印基膜表面；
g)进行待移印基膜的金属化蒸镀，基膜上带有屏蔽油的花纹部分没有被蒸镀上金属。
优选的方案中，上述步骤d)中油泵3向油管7泵入屏蔽油的速度等于步骤f)中油管7的油管蒸发口9屏蔽油蒸汽喷出速度；基膜驱动电机驱动待移印基膜匀速前进，带动花纹辊11和陶瓷辊10反向匀速转动；步骤f)中得到的待移印基膜表面上被转移的花纹以花纹辊11的周长为周期重复。
可以看出，本发明金属化安全薄膜的移印方法是将屏蔽油储存在常温下的储油罐1中，工作时，含微处理控制器的步进电机4根据设定好的转速，带动油泵3，通过硅胶管从储油罐1中吸取相对量的屏蔽油，然后经过硅胶管和油管的进油口6注射到油管7的内腔中。之后，加热电阻8工作，保证恒定的油管温度，将油管7内腔中的屏蔽油及时通过油管蒸发口9蒸发到陶瓷辊10的表面，陶瓷管10与花纹辊11咬合接触，并沿相反方向转动，以此可以将陶瓷辊10表面的屏蔽油转移到花纹辊11的接触面上，花纹辊11与待移印基膜接触，并通过基膜驱动电机驱动待移印基膜，从而带动花纹辊11和陶瓷辊10转动，花纹辊11的花纹就可移印到基膜12的表面，金属层蒸镀过程，有屏蔽油的花纹区域镀不上金属。
实施例3：
一种金属化安全薄膜的屏蔽油移印方法，具体过程为，含微处理控制器的步进电机4控制的油泵3通过固定直径的硅胶管，将油罐1中的屏蔽油，经油管进油口6到达油管7内腔，比如某一规格的待移印膜产品每一万方米的需油量为4.8mL，待移印基膜的运行速度为10m/s，运行一万米需要的时间为16.7min，所以每分钟的用油量为约0.2874ml/min(即4.8ml/16.7min)；同 时，根据硅胶管内径计算的油泵3的抽油量为0.02ml/转，获得步进电机4的转速可设定为约14.37转/min(即0.2874/0.02)。可以看出，不同规格的待移印基膜，根据需油量的要求，即可推算出步进电机4的转速；通过温控系统控制加热电阻8工作，比如，某屏蔽油的沸点为120℃，使加热电阻8工作以保证油管7恒定的油管温度130℃，即屏蔽油处于沸腾状态，将油管7内腔中的屏蔽油及时通过油管蒸发口9蒸发到陶瓷辊10的表面，陶瓷管10与花纹辊11直接接触，并沿相反方向转动，以此将陶瓷辊10表面的屏蔽油转移到花纹辊11的接触面上；因为基膜驱动电机驱动待移印基膜运行，带动花纹辊11和陶瓷辊10反向转动，因花纹辊11与待移印基膜呈弧面接触，花纹辊11的花纹就可移印到待移印基膜的表面，金属层蒸镀过程，有屏蔽油的花纹区域镀不上金属。
通过上述实施例，可以看出如何通过含微处理器的步进电机4控制油泵3将屏蔽油精准注射到油管7内，然后通过热量将屏蔽油及时蒸发到花纹辊11表面，进而移印到基膜。
含微处理器的步进电机控制油泵，实现油量供给的量化和精准，也避免了屏蔽油一致存放在油管中反复加热老化的问题。同时，油量的定量持续供给，也降低人员经验操作的风险，提高镀膜油量控制的可靠性和一致性。
以上已经描述了本发明的各实施例，上述说明是示例性的，并非穷尽性的，并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的。因此，本发明的保护范围应该以权利要求的保护范围为准。
