技术领域 technical field
本发明涉及一种在产品表面贴护膜的方法。The invention relates to a method for pasting a protective film on the surface of a product.
背景技术 Background technique
一般的电脑及其周边产品、通信电子产品、液晶电视等,在出厂前为了防止产品表面被刮伤,所以在制程中需要在产品外表面的重点部位贴覆护膜以提供保护;所述护膜是一种薄状塑料膜(可以是PE、PEP、PP等材质),其贴覆的方式,均采用人工背胶贴覆作业及配合治具压合进行贴覆;首先,需要在整张的塑料护膜一面上先行将胶料完全涂布其上(即一般所称的背胶或上胶),然后将背胶后的整张护膜贴覆在需要保护的产品表面上,再切除超出产品表面需要保护位置以外的不必要护膜。For general computers and their peripheral products, communication electronic products, LCD TVs, etc., in order to prevent the surface of the product from being scratched before leaving the factory, it is necessary to stick a protective film on the key parts of the outer surface of the product during the manufacturing process to provide protection; the protective film The film is a thin plastic film (which can be made of PE, PEP, PP, etc.). On one side of the plastic protective film, the glue is completely coated on it (that is, commonly known as back glue or gluing), and then the whole protective film after the back glue is attached to the surface of the product to be protected, and then cut off Unnecessary protective film extending beyond where the product surface needs to be protected.
前述现有的贴护膜方法,常会因为覆膜时受到气候、湿度、人工贴覆技术熟练度差异等内、外在因素的影响,使得产品覆膜完成后,产品表面与护膜间有空气存在致形成气泡,极不雅观;另者,护膜上胶的品质与厚度因为受到人工作业熟练度的影响,如果无法均匀涂布,会造成消费者撕掉护膜时产生不均匀的残胶留在产品表面上,必须要使用溶剂来擦拭去除,若消费者一时不察使用了有机溶剂来擦拭,则可能对产品表面的烤漆造成不良甚至无可回复的影响。再者,在工厂里施工覆膜时,如果连下几天雨致空气湿度增加,则将护膜贴于产品上时,护膜与产品表面之间会渗入气体,导致看上去会有白雾状层存在,极不雅观,如此众多问题常造成生产者的困扰,若重新贴膜,则又浪费工时、增加成本。The above-mentioned existing protective film method is often affected by internal and external factors such as climate, humidity, and artificial sticking technology proficiency differences when covering the film, so that after the product is covered, there is air between the product surface and the protective film. The existence of air bubbles is very unsightly; on the other hand, the quality and thickness of the protective film are affected by the proficiency of manual work. If it cannot be evenly coated, it will cause uneven residue when consumers tear off the protective film. The glue left on the surface of the product must be removed by wiping with a solvent. If the consumer accidentally uses an organic solvent to wipe it, it may cause adverse or even irreversible effects on the baking varnish on the product surface. Furthermore, when the film is applied in the factory, if it rains for several days and the air humidity increases, then when the protective film is attached to the product, gas will infiltrate between the protective film and the surface of the product, resulting in white fog It is extremely unsightly, and so many problems often cause troubles for producers. If the film is re-attached, it will waste man-hours and increase costs.
另一方面,现有的覆膜方式因为需要在整张护膜一面将胶料完全涂布其上,致使胶料的使用量非常大,成本一直无法降低;然而,对产品进行覆膜工作已属微利行业,若不戮力寻求降低成本的作业方式,已几乎无利可图。On the other hand, because the existing film covering method needs to completely coat the glue on one side of the entire protective film, the amount of glue used is very large, and the cost has been unable to be reduced; however, the work of laminating the product has been It is a meager profit industry, and if you don't try your best to find ways to reduce costs, it will be almost unprofitable.
再者,目前较进步取代人工作业来进行覆膜的方法,则是利用离型纸配合转印方式来上胶;其作业方式是先将胶料预先涂布于离型纸上待用,欲进行上胶时,则对离型纸进行烘烤,使其上的胶料软化,然后将离型纸对合于护膜上,再对其施加压力,使离型纸上的胶料转印至护膜。此种转印方法虽然较传统人工作业方式具有更高的效率,惟,需要使用大量的离型纸,材料成本仍居高不下。因此,本发明人基于不能降低覆膜品质与经济规模的原则下,极力改善覆膜的方法,经不断的试作与验证,终于研制出本发明。Furthermore, the current more advanced method to replace manual operations for lamination is to use release paper with transfer printing to apply glue; the operation method is to pre-coat the glue on the release paper for later use. When gluing is desired, the release paper is baked to soften the glue on it, and then the release paper is placed on the protective film, and pressure is applied to make the glue on the release paper turn. Print to pellicle. Although this transfer printing method has higher efficiency than the traditional manual method, it needs to use a large amount of release paper, and the material cost remains high. Therefore, based on the principle of not reducing the quality of the coating and economical scale, the inventor tried his best to improve the method of coating, and finally developed the present invention through continuous trial and verification.
