Description
本創作係關於一種印刷網版的結構,特別是指一種當網版於印刷時,可減緩印刷衝擊的網版結構。This creation is about the structure of a printing screen, especially a screen structure that can reduce the impact of printing when the screen is printing.
圖1a為一示意圖,用以說明習知技術中印刷網版的印刷過程一;圖1b為一示意圖,用以說明習知技術中印刷網版的印刷過程二;圖1c為一示意圖,用以說明習知技術中印刷網版的印刷過程三。請參照圖1a至圖1c,在網版的印刷習知技術中大部分採用離版印刷,即是將網版1置於待印物2的上方,之後會藉由刮刀3而將漿料或油墨從網布101上的印刷區A1刮至待印物2上以形成印刷圖案。由圖1a可看出,刮刀3的設定行程會大於待印物2的面積,當刮刀3施加下壓力量時會對網布101加壓,進而造成壓力點P1以及壓力點P2,壓力點P1即為刮刀3與網布101之間的施力點,壓力點P2即為網布101與待印物2邊緣的彎折點,此時,若待印物2四周較為尖銳,將會藉由壓力點P2而對網布101造成損傷。Fig. 1a is a schematic diagram for explaining the printing process of the printing screen in the conventional technology; Fig. 1b is a schematic diagram for explaining the printing process of the printing screen in the conventional technology; Fig. 1c is a schematic diagram for Explain the printing process of printing screens in conventional technology. Please refer to FIG. 1a to FIG. 1c. In the conventional printing technology of screen printing, most of them use off-screen printing, that is, the
再由圖1b可看出,刮刀3會從壓力點P2開始施力而將漿料或油墨從網布101上的印刷區A1刮至待印物2上以形成印刷圖案,此時,若刮刀3的下壓力道過大,印刷速度快,容易使漿料或油墨從入刀處,即壓力點P2溢出。由圖1c可看出,刮刀3的行程最後會走到壓力點P3。As can be seen from FIG. 1b, the
此外,當待印物2為太陽能多晶與單晶晶圓時,太陽能多晶與單晶晶圓在其四角容易將網布101刺破。In addition, when the object to be printed 2 is a solar polycrystalline and single crystal wafer, the solar polycrystalline and single crystal wafer easily punctures the
由上述的習知技術可知,目前的印刷網版結構會在印刷過程中產生網版損傷。基於上述理由,如何提供一種在印刷過程中可減緩印刷衝擊的網版結構,進而使網版不會受到損傷,乃是待解決的事項。It can be known from the above-mentioned conventional technology that the current printing screen structure will cause screen damage during the printing process. Based on the above reasons, how to provide a screen structure that can reduce the impact of printing during the printing process, so that the screen will not be damaged, is a matter to be solved.
為達成前述目的,本創作係提供一種減緩印刷衝擊的網版結構,包括:一網框;一網布,拉伸並固定於該網框上,該網布上包括一印刷區,且該網布包括一刮刀面及一貼印面;一乳劑層,塗佈並設置於該網布的四個轉角上;一高分子材料層,設置於該網布位於該貼印面的一側上;以及一氣墊層,設置於該乳劑層與該高分子材料層之間。In order to achieve the foregoing purpose, the creative department provides a screen structure that reduces the impact of printing, including: a screen frame; a screen cloth, stretched and fixed on the screen frame, the screen cloth includes a printing area, and the screen The cloth includes a doctor blade surface and a printing surface; an emulsion layer coated and disposed on the four corners of the mesh fabric; a polymer material layer disposed on the side of the mesh fabric on the printing surface; and a An air cushion layer is provided between the emulsion layer and the polymer material layer.
較佳地,該高分子材料層進一步設置於該網布位於該刮刀面的一側上。Preferably, the polymer material layer is further disposed on one side of the mesh cloth on the blade surface.
較佳地,當該網布的該貼印面與置於一待印區上的一待印物貼合時,該氣墊層疊在該待印物的邊緣上。Preferably, when the printing surface of the mesh cloth is attached to an object to be printed placed on an area to be printed, the air cushion is laminated on the edge of the object to be printed.
較佳地,於該網布的該四個轉角的該乳劑層向該貼印面凸出。Preferably, the emulsion layers at the four corners of the mesh cloth protrude toward the printing surface.
較佳地,凸出的該乳劑層與該待印物上的一印刷圖形之間的距離為800μm。Preferably, the distance between the protruding emulsion layer and a printed pattern on the object to be printed is 800 μm.
較佳地,該氣墊層沿著該印刷區的轉角設置。Preferably, the air cushion layer is disposed along the corner of the printing area.
較佳地,該氣墊層沿著該印刷區的邊緣設置。Preferably, the air cushion layer is disposed along the edge of the printing area.
以下配合圖式及元件符號對本創作之實施方式做更詳細的說明,俾使熟習該項技藝者在研讀本說明書後能據以實施。The following describes the implementation of this creation in more detail with reference to drawings and component symbols, so that those skilled in the art can implement it after studying this manual.
圖2為一示意圖,用以說明本創作一實施例的減緩印刷衝擊的網版結構;圖3為一示意圖,用以說明圖2中的A-A剖面結構。請參照圖2及圖3,在本創作一實施例中,減緩印刷衝擊的網版結構4包括一網框40、一網布42、一乳劑層44、一高分子材料層46以及一氣墊層48。網布42是拉伸並固定於網框40上,網布42上包括一印刷區A2,且網布42包括一刮刀面S1及一貼印面S2。乳劑層44是塗佈並設置於網布42的四個轉角上,即轉角C1、轉角C2、轉角C3以及轉角C4。高分子材料層46是設置於網布42位於貼印面S2的一側上。氣墊層48是設置於乳劑層44與高分子材料層46之間。FIG. 2 is a schematic diagram illustrating the screen structure for reducing printing impact according to an embodiment of the present invention; FIG. 3 is a schematic diagram illustrating the A-A cross-sectional structure in FIG. 2. 2 and 3, in an embodiment of the present creation, the
其中,是藉由塗佈乳劑於網布42的四個轉角上並進行曝光顯影而形成乳劑層44,且在本創作一實施例中,網布42的四個轉角上的乳劑層44可向貼印面S2凸出,如圖3所示,以利氣墊層48的形成,而在本創作其他實施例中,網布42的四個轉角上的乳劑層44可貼平於網布42上。高分子材料層46可為一薄膜並直接貼附於網布42位於貼印面S2的一側上,並藉由貼合製程以在乳劑層44與高分子材料層46之間形成氣墊層48。再者,在本創作一實施例中,可藉由雷射顯影製程而在網布42上形成一印刷區A2,並可同樣藉由雷射顯影製程以在高分子材料層46上形成對應印刷區A2中的圖案的印刷區A3。Wherein, the
另一方面,在本創作一實施例中,氣墊層48是沿著印刷區A2的邊緣的轉角設置,詳細而言,是設置於網布42上印刷區A2的轉角處C1、轉角處C2、轉角處C3及轉角處C4上,以在網布42的左右對稱處形成八字結構,並藉由氣墊層48減緩網版結構4於印刷時的衝擊。On the other hand, in an embodiment of the present creation, the
圖4為一示意圖,用以說明本創作一實施例的減緩印刷衝擊的網版結構與待印物之間的關係。請參照圖3及圖4,在本創作一實例中,當網布42的貼印面S2與置於一待印區20上的一待印物2貼合以進行網版印刷作業時,氣墊層48會疊在待印物2的邊緣上,如圖4中的導引虛線中的區間所示。如此一來,當網布42與待印物2接觸並使用刮刀以刮入油墨時,可藉由氣墊層48提供印刷緩衝,避免網布42被待印物2的邊緣刮傷或刺破。再者,當刮刀施力於網布42上,以將油墨經由刮刀面S1刮入印刷區A2並在待印物2上形成印刷圖案22時,同樣可藉由氣墊層48來減緩印刷衝擊,避免刮刀施力於網布42上的壓力過大而刮傷網布42。FIG. 4 is a schematic diagram illustrating the relationship between the screen structure for reducing printing impact and the object to be printed according to an embodiment of the present invention. Please refer to FIGS. 3 and 4. In an example of this creation, when the printing surface S2 of the
值得一提的是,再請參照圖3及圖4,在本創作一實施例中,凸出的乳劑層46與印刷區A2之間的距離d1為800μm。另一方面,氣墊層48的寬度d2及氣墊層48的厚度可依實際需求而做調整,以對網布42提供最佳的緩衝效果。It is worth mentioning that please refer to FIGS. 3 and 4 again. In an embodiment of the present creation, the distance d1 between the
圖5為一示意圖,用以說明本創作另一實施例的減緩印刷衝擊的網版結構的剖面結構。請參照圖5,在本創作另一實施例中,高分子材料層46進一步設置於網布42位於刮刀面S1的一側上,且可藉由雷射顯影製程以在高分子材料層46上形成對應印刷區A2的圖案的印刷區A4。於刮刀面S1進一步設置高分子材料層46可進一步對網布42作保護,並減緩刮刀對網布42所造成的衝擊。FIG. 5 is a schematic diagram illustrating a cross-sectional structure of a screen structure for reducing printing impact according to another embodiment of the present invention. Referring to FIG. 5, in another embodiment of the present invention, the
圖6為一示意圖,用以說明本創作再一實施例的減緩印刷衝擊的網版結構。請參照圖6,在本創作再一實施例中,一種減緩印刷衝擊的網版結構6包括一網框60、一乳劑層62、一網布64、一高分子材料層(未於圖中示出)以及一氣墊層(未於圖中示出)。此實施例的改變為,乳劑層62是以環繞方式設置於網布64的邊緣C上,而整個網布64即為印刷區,因此同樣是將氣墊層沿著印刷區的邊緣C設置,以藉由氣墊層圍繞整個網布64。FIG. 6 is a schematic diagram illustrating a screen structure for reducing printing impact according to another embodiment of the present creation. Please refer to FIG. 6, in yet another embodiment of the present creation, a
由上述內容可知,本創作成功的提供了一種減緩印刷衝擊的網版結構。在本創作中,可藉由在網版結構上設置一氣墊層,使的網版結構於印刷時,可藉由氣墊層對網版結構的網布提供緩衝,避免網布被待印物的邊緣或刮刀刮傷,亦避免刮刀施力於網布的壓力過大而破壞。From the above, it can be seen that this creation successfully provides a screen structure that reduces the impact of printing. In this creation, an air cushion layer can be provided on the screen structure, so that the screen structure can be used to provide cushioning for the screen fabric of the screen structure during printing, so as to prevent the screen fabric from being printed. If the edge or scraper is scratched, the pressure of the scraper on the mesh cloth is too large to damage it.
以上所述者僅為用以解釋本創作之較佳實施例,並非企圖據以對本創作做任何形式上之限制,是以,凡有在相同之創作精神下所作有關本創作之任何修飾或變更,皆仍應包括在本創作意圖保護之範疇。The above are only the preferred embodiments to explain this creation, not to attempt to restrict the creation in any way, so any modification or change to the creation under the same spirit of creation , Should still be included in the scope of protection of this creative intention.
