Abstract

The invention relates to a binding method for a capacitive touch screen, which comprises the following steps: evenly coating ultraviolet curable resin on the binding face of a first board body to serve as a bonding layer; then, performing binding in a vacuum environment; and finally, removing the vacuum environment, and fully curing the bonding layer by adopting ultraviolet irradiation so as to firmly bind the first board body with a second board body together. The first board body and the second board body are bound in the vacuum environment, and therefore, a bubble problem cannot exist between the first board body and the second board body, and the binding of large-sized board bodies can be realized. As the ultraviolet curable resin is coated evenly, and in the coating process, the use level of the ultraviolet curable resin and area are in direct ratio, the use level of the ultraviolet curable resin can be accurately controlled, so that large-area flowing cannot occur after the binding is finished, thereby, the thickness and the stress of all areas are quite uniform. The first board body and the second board body can be bound in a board-jointed state. The binding method for the capacitive touch screen is suitable for manufacturing board-jointed capacitive touch screens, and has higher production efficiency.

[0001] 本发明涉及一种贴合方法,尤其涉及一种电容触摸屏的贴合方法。 [0001] The present invention relates to a bonding method, particularly to a bonding method for a capacitive touch screen. 背景技术 Background technique

[0002] 近年来,随着信息技术、无线行动通讯和信息家电的快速发展与应用,人们对电子产品的依赖性与日俱增。 [0002] In recent years, with the rapid development of information technology, wireless communications and mobile information appliances and applications, increasing people's dependence on electronics. 为了达到更便利,体积更轻巧化以及更人性化的目的,许多电子产品已由传统的键盘或鼠标作为输入装置,转变为使用设置在显示屏前的触摸屏作为输入装置。 In order to achieve a more convenient volume of more compact and more humane purposes, many electronic products has been the traditional keyboard or mouse as an input device, into a use is provided in front of the display screen as a touch screen input device. 现有的触摸屏大致可分为电容式、电阻式、感光式等类型。 Conventional touch screen can be divided into capacitive, resistive type, a photosensitive type and other types. 其中,电容触摸屏已经广泛应用到各类电子产品,例如手机、平板电脑中。 Among them, the capacitive touch screen has been widely applied to various electronic products such as mobile phones, tablet. 电容触摸屏的特点是透过率高且触摸施压不必用力,工作时还可以实现多个触摸点的同时探测,操作使用更为人性化。 Features capacitive touch screen does not have to be forced through the high pressure and touch, work, also can implement multiple touch points simultaneously detect, operation more humane.

[0003] 电容触摸屏一般为由多个板体相互贴合构成的贴合体,例如将设置有感应电路的感应板与具有美观、保护作用的覆盖板贴合在一起构成电容触摸屏。 [0003] Usually the plurality of capacitive touch screen plate bodies bonded to each other by an adhesive element made of, for example, is provided with a sensing circuit of the sensing plate having aesthetic, protective effect cover plate bonded together to form a capacitive touch screen. 另外,将电容触摸屏设置到平板显示屏前面时,也需要将电容触摸屏与平板显示屏贴合。 Further, the capacitive touch screen is provided in front of the flat screen, also requires the capacitive touch screen and flat screen bonded. 为了避免相贴合两个板体之间的空气界面反射光,获得更好的阳光下可读性,目前一般是采用透明粘合层进行贴 In order to avoid an air interface are bonded together between the two reflected light plate, for better readability of the sun, is a general transparent adhesive layer affixed

I=IO I = IO

[0004] 无论是电容触摸屏本身多个板体的相互贴合,还是电容触摸屏与平板显示屏的贴合,都涉及到将两个硬质的第一板体与第二板体贴合在一起的技术,目前一般采用可固化树脂进行贴合,其贴合方法一般包括如下步骤: [0004] either a capacitive touch screen itself bonded to each of the plurality of plate bodies or the capacitive touch screen and the flat screen bonded, are related to the two rigid first plate and the second plate together considerate technology, general use of the curable resin bonding, bonding method which generally comprises the steps of:

[0005] (1)、将第一板体的贴合面朝上; [0005] (1), the first plate is bonded to the face;

[0006] (2)、在第一板体的贴合面上涂布图形为星状(即具有多个延伸脚)的可固化树脂; [0006] (2), the bonding surface of the first plate is coated stellate pattern (i.e., having a plurality of legs extending) a curable resin;

[0007] (3)、将第二板体的贴合面与第一板体的贴合面相对,并迅速将第二板体盖住第一板体; [0007] (3), the bonding surface bonded to the surface of the second plate opposite the first plate, second plate and quickly cover the first plate member;

[0008] 0)、夹压第一板体和第二板体,使得星状可固化树脂的面积逐渐膨胀,最后布满第一板体与第二板体之间的缝隙,第一板体与第二板体之间的空气通过可固化树脂的各个延伸脚之间的缝隙被挤出。 [0008] 0), a first pinch plate and the second plate, so that the area of ​​the stellate curable resin is gradually expanded, and finally covered with a gap between the first plate and the second plate, a first plate and air between the second plate member extending through a gap between the respective legs of the curable resin to be extruded.

[0009] (5)、采用紫外光对其进行照射,使得上述可固化树脂被固化,形成第一板体与第二板体之间牢固的粘合层。 [0009] (5), it was irradiated using ultraviolet light, so that said curable resin is cured to form a strong bonding layer between the first plate and the second plate member.

[0010] 这种方法,具有以下的缺点: [0010] This method has the following disadvantages:

[0011] 1、无法实现大尺寸板体的贴合,在大尺寸板体贴合的情况下,气泡往往无法从可固化树脂的各个延伸脚之间的缝隙被挤出; [0011] 1, can not achieve a large-sized plate is bonded, in the case of large-sized panels generally conform, bubbles are often unable to be extruded from the gap extending between the respective leg of the curable resin;

[0013] 3、均勻性难以控制,由于在受压过程中,可固化树脂需要在缝隙中流动,由于不同位置难以达到一致的流动状态,因此容易导致最终不同区域的厚度、应力不一致。 [0013] 3, uniformity is difficult to control, since the gap needs to flow in the compression process, the curable resin, due to the different positions difficult to achieve uniform flow state, it is easy to lead to a final thickness in different regions, the stress is inconsistent. 尤其当其中一板体为平板显示屏时,还会使得平板显示屏的表面受力不均勻,最终导致出现显示不均的缺陷。 Especially when one plate of the flat screen, so that also the surface discontinuity of the flat screen, resulting in display unevenness defects.

[0014] 4、粘合层会影响到板体的切割,因此这种贴合方法只适合用于单元产品的贴合, 而难以用于拼板产品(多个单元的基板还没被切割开,后续需要再进行切割)的贴合,难以具有较高的生产效率。 [0014] 4, the adhesive layer will affect the cutting plate, so this method is only suitable bonding means for bonding the product, it is difficult for the substrate and product puzzle (s cells are not cut apart subsequent need to be cut) is bonded, it is difficult to have a high production efficiency.

[0016] 一种电容触摸屏的贴合方法,包括将第一板体与第二板体相贴合,其特征在于第一板体与第二板体相贴合包括如下步骤: [0016] The bonding method of a capacitive touch screen, comprising a first plate and the second plate are bonded together, characterized in that the first plate and the second plate are bonded together comprising the steps of:

[0017] (1)、在第一板体的贴合面上,均勻地涂布上一层厚度为0. 01〜0. 3mm的紫外固化树脂作为粘合层; [0017] (1), the engagement surface of the first plate is attached, the uniformly coated to a thickness of 0. 01~0 3mm UV curing resin as an adhesive layer;

[0018] (2)、将第一板体和第二板体放置于气压为0〜50½的真空环境中; [0018] (2), the first plate and the second plate is placed in a vacuum pressure environment in 0~50½;

[0019] (3)、将第二板体压合在粘合层上,第一板体、粘合层和第二板体构成贴合体; [0019] (3), a second plate laminated on the adhesive layer, a first plate member, the adhesive layer and the second plate member constituting the bonded body;

[0020] 压合时应将第二板体的贴合面与第一板体的贴合面相对;在此步骤中,紫外固化树脂基本充分地填充在第一板体与第二板体之间; [0020] The bonding surface of the bonding surface shall press when the second plate relative to the first plate; In this step, an ultraviolet curable resin is sufficiently filled in the first base plate and the second plate of between;

[0021] (4)、撤掉真空环境,使贴合体在大气压的作用下进一步受到夹压作用; [0021] (4), removed the vacuum environment, so that a laminated body is further subjected to crimping under the action of the atmospheric pressure;

[0022] 在此步骤中,由于贴合体受到大气压的夹压作用,使得紫外固化树脂在第一板体与第二板体之间填充的充分度进一步地提高; [0022] In this step, since the bonded body subjected to nip the atmospheric pressure, so that the ultraviolet curing resin is filled between the first plate and the second plate of the further improved sufficiently;

[0023] (5)、采用紫外线光照射,对粘合层进行充分地固化,使第一板体和第二板体牢固地贴合在一起。 [0023] (5), using irradiated with ultraviolet light, the adhesion layer is sufficiently cured, the first plate and the second plate member are firmly bonded together.

[0024] 上述第一板体和第二板体可以均为电容触摸屏的板体,例如第一板体为电容触摸屏的覆盖板,第二板体为电容触摸屏的感应板;第一板体和第二板体也可以是:其中之一为电容触摸屏,另一为平板显示器的显示屏。 [0024] The first plate and the second plate member may each plate capacitive touch screen, such as a first plate of a capacitive overlay touch screen, the second plate of a capacitive touch screen sensor panel; and a first plate the second plate may be: one is a capacitive touch screen, the other is a flat panel display screen.

[0025] 紫外固化树脂即是可通过采用紫外线光进行固化的可固化树脂,例如:添加有紫外固化组分的环氧丙烯酸酯树脂、聚氨酷丙烯酸酯、不饱和聚酯、聚甲基丙烯酸甲酯(PMMA)、有机硅化合物等透明材料。 [0025] UV-curable resin that is by using an ultraviolet light curable resin is cured, for example: epoxy acrylate resin is added with a UV-curable component, cool polyurethane acrylates, unsaturated polyesters, polymethacrylate transparent material methyl ester (PMMA), an organic silicon compound.

[0026] 由于在上述过程中,第一板体与第二板体的贴合是在真空环境下进行的,因此第一板体与第二板体之间不会存在气泡问题,能够实现大尺寸板体的贴合;由于采用均勻涂布方式涂布紫外固化树脂,在涂布的过程中,其用量与面积成正比,因此能够准确控制紫外固化树脂的用量,使得在贴合之后不会出现大面积的流动,从而使得各个区域的厚度、应力都相当均勻。 [0026] Since the above-described process, the first plate and the second plate is bonded in a vacuum environment, so there will be no problem of air bubbles between the first plate and the second plate member, it is possible to achieve a large the size of the bonded plate; As a result a uniform coating an ultraviolet curable resin coating method, the coating process in an amount proportional to the area, it is possible to accurately control the amount of ultraviolet curing resin, so as not after bonding a large area of ​​flow occurs, so that the thickness of each area, are relatively uniform stress. 此外,还可以对紫外固化树脂的涂布方式作进一步的控制,使得紫外固化树脂只涂布在需要粘合的区域,而其他区域则不涂上紫外固化树脂,或者说,按照一定的图形进行涂布紫外固化树脂,形成一定图形的粘合层;因此,只需要选择在切割的部位不涂布紫外固化树脂,则紫外固化树脂的涂布、第一板体与第二板体的贴合可以在拼板状态上进行,适用于拼板电容触摸屏的制造,具有较高的生产效率。 In addition, also can be used for ultraviolet curing resin coating method further control, so that the ultraviolet curing resin is applied only to the area in need of an adhesive, while other regions are not coated with an ultraviolet curable resin, or, according to a certain pattern applying an ultraviolet curable resin, an adhesive layer to form a certain pattern; Thus, not only need to select a coating ultraviolet curing resin is applied in the cut portion, the ultraviolet curable resin, attached to the first plate and the second plate is bonded state may be performed on a puzzle, the puzzle for the manufacture of capacitive touch screen, with high production efficiency.

[0027] 作为本发明的优选方案,其特征在于所述步骤(1)中紫外固化树脂采用的涂布方式如下:采用一具有夹缝状涂胶嘴的涂胶器,并将涂胶器的位置固定,涂胶嘴向下,第一板体勻速通过涂胶嘴的下方,紫外固化树脂从涂胶嘴的夹缝中挤出,均勻涂布在第一板体的贴合面上。 [0027] As a preferred embodiment of the present invention, wherein said step (1) described coating an ultraviolet curable resin used is as follows: using a nozzle having a slit-shaped applicator coating, and the position of the adhesive applicator fixed, the dispense nozzle downwardly through the first plate below the uniform coating of the nozzle, ultraviolet curable resin is extruded from a slit nozzle coating, the bonding surface of the first plate is coated uniformly. 采用上述涂布方式,形成的粘合层非常均勻,从而使得贴合后,各个区域的厚度、 应力都相当均勻。 After coating the above-described embodiment, the adhesive layer is very uniform, so that the bonding, the thickness of each region, are relatively uniform stress.

[0028] 作为本发明的另一种优选方案,其特征在于:所述步骤(1)中紫外固化树脂采用的涂布方式为印刷方式。 [0028] As another preferred embodiment of the present invention, wherein: said step (1) in the ultraviolet-curing resin coating method employed is printing. 印刷方式可以为丝印,也可以为喷墨印刷等方式。 It may be a silk screen printing, inkjet printing or the like may be manner. 采用印刷方式, 能够使得紫外固化树脂被涂布在需要粘合的区域,而其他区域则不会涂布上紫外固化树脂,从而达到按照一定图形进行涂布紫外固化树脂的目的。 By printing, it is possible that the ultraviolet curing resin is applied to the area in need of an adhesive, while other regions are not applied on the ultraviolet curable resin, so as to achieve an ultraviolet curable resin is coated according to a certain pattern.

[0029] 作为本发明进一步的优选方案,其特征在于:所述第一板体和第二板体为拼板,第一板体的贴合面上设有切割线、贴合区域和非贴合区域;所述步骤(1)中,紫外固化树脂印刷在第一板体的贴合面上的贴合区域中。 [0029] As a further preferred embodiment of the present invention is characterized in that: said first plate and the second plate is a puzzle, with bonding surface of the first plate body cutting line, and non-adherent bonding region bonding region; said step (1), printed on the ultraviolet curing resin bonding surface of the first plate attached to the engagement area.

[0030] 由于紫外固化树脂在固化之前具有流动性,当粘合层的厚度大于30 μ m时,通过印刷方式形成的粘合层在放置一定时间后,其图形会变得模糊,为了使在贴合前粘合层保持固定的图形,作为本发明进一步的优选方案,其特征在于:在所述步骤(1)与步骤(2)之间,对粘合层进行预固化。 [0030] Since the ultraviolet curing resin having fluidity prior to curing, when the thickness of the adhesive layer is larger than 30 μ m, the adhesive layer is formed by printing a predetermined time after placement, which becomes blurred pattern, in order to make before bonding adhesive layer to maintain a fixed pattern, as a further preferred embodiment of the present invention is characterized in that: in (2) said step (1) and the step of pre-cure the adhesive layer. 即是使粘合层半固化(紫外固化树脂的聚合度为40%〜80%之间)而失去流动性,但依然保持一定的可塑性和粘性。 That is to make the semi-cured adhesive layer (ultraviolet curing resin polymerization degree of between 40% ~ 80%) and loses its fluidity, but still maintain a certain plasticity and viscosity. 对粘合层进行预固化,可以采用加热的方式,蒸发掉粘合层中部分的挥发性组分;也可以采用较小曝光量的紫外线光进行照射, 使粘合层内部发生较轻度的固化反应。 Of the adhesive layer is pre-cured, the heating mode may be employed, the adhesive layer was evaporated volatile component portion; small exposure amount of ultraviolet light is irradiated may also be employed, so that occurrence of inner bonding layer of lightly curing reaction.

[0031] 作为本发明更进一步的优选方案,其特征在于:所述对粘合层进行预固化在步骤⑴之后的1分钟内进行。 [0031] As a still further preferred embodiment of the present invention is characterized in that: said pre-performed for 1 minute after the step of curing the adhesive layer ⑴.

[0032] 当电容触摸屏的粘合层的厚度要求大于100 μ m时,作为本发明的优选方案,其特征在于:在步骤(1)与步骤(¾之间,第二板体的贴合面上涂布另一粘合层作为增厚层,并在1分钟内对该粘合层进行完全固化。在这种情况下,步骤(1)中第一板体的贴合面上的粘合层起到粘合作用,而本步骤中,第二板体的贴合面上的粘合层起到增厚的作用,从而使得贴合效果更好。 [0032] When the thickness of the adhesive layer is greater than the capacitive touch screen of claim 100 μ m, as a preferred embodiment of the present invention is characterized in that: the bonding surface in step (1) and the step (¾ between, the second plate member another adhesive layer is coated as a thickening layer, and the adhesive layer is fully cured in 1 minute. in this case, the step of bonding the adhesive surface of the paste (1) of the first plate adhesion layer functions, but this step, the adhesive surface of the laminated second plate affixed play thickening effect, so that better fit.
