Description
本發明與鏡片揉膠裝置有關,特別是指一種可以自動化方式達成均勻塗抹黏膠的鏡片揉膠裝置。The present invention relates to a lens kneading device, in particular to a lens kneading device that can achieve uniform application of viscose in an automated manner.
在製作眼鏡鏡片或攝影鏡頭鏡片的過程中,有時需要將兩個鏡片用黏膠黏合在一起,以形成一複合的光學元件,而在黏合過程中,黏膠需抹勻在兩鏡片的交界面上,且黏膠內不得有氣泡殘留,否則光線行進的路徑將因此產生偏折而減損其光學效果。為達上述目的,以往皆以人工方式將兩鏡片揉合,採用此方式能使兩鏡片交界面的各個部分都能受到擠壓,進而使黏膠能均勻塗抹於兩鏡片的交界面並排出黏膠內的氣泡,但用人工方式不僅耗時高、缺乏效率,還容易使工作者產生手部的職業傷害。In the process of making spectacle lenses or photographic lens lenses, it is sometimes necessary to bond two lenses together with glue to form a composite optical element. During the bonding process, the glue needs to be spread evenly on the intersection of the two lenses. On the interface, there must be no air bubbles remaining in the glue, otherwise the path of the light will be deflected and reduce its optical effect. In order to achieve the above purpose, the two lenses are manually kneaded in the past. In this way, all parts of the interface of the two lenses can be squeezed, so that the adhesive can be evenly applied to the interface of the two lenses and the adhesive can be discharged. The air bubbles in the glue, but manual methods are not only time-consuming and inefficient, but also easily cause occupational injuries to workers' hands.
為了解決上述不便,目前有業者開發出用於鏡片揉膠的自動化裝置,如WO 95/13904號專利案,該裝置先將上、下兩鏡片壓密後,接著驅動上鏡片進行同軸心的旋轉,然而在採用同軸心的旋轉方式,其黏膠頂多只能由其塗覆處產生擴散的效果,並無法使黏膠抹勻於兩鏡片的交界面,也無法使黏膠內氣泡完全排出。In order to solve the above inconvenience, some companies have developed an automated device for lens rubber kneading, such as Patent WO 95/13904, which first compacts the upper and lower lenses, and then drives the upper lens to rotate concentrically. However, in the use of a concentric rotation method, the adhesive can only be diffused from the coating area, and the adhesive cannot be evenly spread on the interface between the two lenses, nor can the bubbles in the adhesive be completely discharged .
又,如CN 208737111號專利案所揭露的自動化揉膠裝置,該裝置將上、下兩鏡片壓密後,接著驅動上鏡片可相對於下鏡片進行一直線往復方向的懸擺移動,但由於上、下鏡片的交界處為一圓周面,因此此種單一方向往復來回的揉膠方式,將造成上、下鏡片於懸擺方向的兩側部位無法受到擠壓,而同樣會有無法使黏膠抹勻,以及無法使黏膠內氣泡完全排出的問題存在。In addition, for example, the automatic rubber kneading device disclosed in CN 208737111 patent case, the device compacts the upper and lower lenses, and then drives the upper lens to move in a linear reciprocating direction relative to the lower lens. The junction of the lower lens is a circumferential surface, so this single direction of reciprocating rubber kneading method will cause the upper and lower lens to be squeezed on both sides of the suspension direction, and it will also prevent the glue from being wiped. There are problems of uniformity and the inability to completely expel the bubbles in the viscose.
有鑒於此,故如何解決上述問題,即為本發明所欲解決之首要課題。In view of this, how to solve the above-mentioned problems is the primary problem to be solved by the present invention.

首先,請參閱第1~3圖所示,為本發明所提供之一種鏡片揉膠裝置1,其主要由一主動桿10、一連動桿20、一鏡片吸盤30及一鏡片放置模具40所組成,其中:First, please refer to Figures 1 to 3, which is a
該主動桿10可被一驅動組60驅動而移動,該驅動組60具有一夾座67、一第一滑動件61、一沿Z軸向延伸之第一滑軌62、一第二滑動件63、一沿X軸向延伸之第二滑軌64、一第三滑動件65、一沿Y軸向延伸之第三滑軌66。該主動桿10被垂直夾設固定在該夾座67上,並朝下延伸形成有一底端,而該夾座67被固設於該第一滑動件61上,再以該第一滑動件61滑設於一第一滑軌62上,使該第一滑動件61可沿Z軸向來回滑動,接著該第一滑軌62再與該第二滑動件63相固接,該第二滑動件63並滑設於該第二滑軌64上,使該第二滑動件63可沿X軸向來回滑動,而該第二滑軌64再與該第三滑動件65相固接,並以該第三滑動件65滑設該第三滑軌66上,使該第三滑動件65可沿Y軸向來回移動,且在實際應用上,該驅動組60可受一控制器(圖中未示)操作,進而帶動該主動桿10可隨該驅動組60而沿著所預先設定的Z、X、Y軸向路徑移動。The
而該連動桿20具有一上端及一下端,且該連動桿20的上端以一萬向接頭結構11連接於該主動桿10的底端。於本實施例中,該主動桿10係於其底端形成一球頭12,而該連動桿20的上端則形成一可對應容設該球頭12的槽座13,並藉該球頭12與該槽座13相互接合即可組成該萬向接頭結構11,使該連動桿10能相對該主動桿10進行多角度方向的偏擺移動,且在該連動桿20未受力的狀態下,該連動桿20將自然向下垂擺而與該主動桿10位在同一軸心上。The
該鏡片吸盤30,用以相對接設於該連動桿20的下端,該鏡片吸盤30具有一第一鏡片固定部31,而一第一鏡片36可相對接設於該第一鏡片固定部31中,該第一鏡片固定部31於其中心處開設有一第一開口32,且該第一開口32朝該鏡片吸盤30內延伸形成有一第一吸氣孔33,且該第一吸氣孔33外接有一第一吸氣管34,該第一吸氣管34又連接一第一吸氣單元35,且當該第一吸氣單元35運作時,可將該第一吸氣孔33中之空氣排出而形成真空狀態,使該第一鏡片36可透過該第一開口32而被吸附固定於該第一鏡片固定部31中。The
該鏡片放置模具40,用以設置於該鏡片吸盤30之相對下方位置處,該鏡片放置模具40具有一第二鏡片固定部41,一第二鏡片46可相對接設於該第二鏡片固定部41中,且該第二鏡片46的上表面曲度與該第一鏡片36的下表面曲度相符,而該第二鏡片固定部41於其中心處開設有一第二開口42,該第二開口42朝該鏡片放置模具40內延伸形成有一第二吸氣孔43,該第二吸氣孔43外接有一第二吸氣管44,該第二吸氣管44又連接一第二吸氣單元(圖中未示),且當該第二吸氣單元運作時,可將該第二吸氣孔43中之空氣排出而形成真空狀態,使該第二鏡片46可透過該第二開口42而被吸附固定於該第二鏡片固定部41中。並界定該鏡片放置模具40的中心軸為一垂直的軸線L,該主動桿10或該鏡片放置模具40至少其中一者可沿該軸線L上下位移,且在該驅動組60未作動時,該主動桿10與該連動桿20之軸心分別對正於該軸線L上;而在該驅動組60作動時,可帶動該主動桿10繞行該軸線L進行一預定的移動路徑。The
而於本實施例中,該鏡片放置模具40被設置於一升降台50上,該升降台50具有一可供組設該鏡片放置模具40之基板51,並於該基板51的中心處向下接設有一氣壓缸52,且於該基板51的兩側分別接設有一朝下延伸之滑桿53,各該滑桿53並分別對應穿設於一導軌座54內,並藉此以形成一線性導軌的結構,使該氣壓缸52之推桿521向上頂撐該基板51時能夠平穩地沿一直線路徑移動而不會歪斜。In this embodiment, the
接著請繼續參閱第4~7圖,藉由上述結構所組成之本發明於實際進行鏡片揉膠作業時,首先利用該第一吸氣單元35與該第二吸氣單元將其第一吸氣孔33與第二吸氣孔43內的空氣抽出而形成真空狀態,使該第一鏡片36與該第二鏡片46可分別被吸附於該第一鏡片固定部31與該第二鏡片固定部41中;接著將黏膠塗抹於該第二鏡片46的上表面,此時該第一鏡片36的中心軸與該第二鏡片46的中心軸皆位於該軸線L上,並驅動該第一滑動件61帶動該主動桿10沿Z軸向下移動,且同時透過該氣壓缸54將該鏡片放置模具40向上頂起,直到該第一鏡片36的下表面與該第二鏡片46的上表面相互貼合。而後透過控制器(例如可程式控制器Programmable Logic Controller,
PLC)所預先設定的驅動組60傳動順序與位移路徑,以控制該驅動組60可帶動該主動桿10繞著該軸線L沿一螺旋狀漸擴軌跡(如第6圖中之虛線箭頭方向所示)移動,細言之,透過預先設定該驅動組60之第二滑動件63與第三滑動件65之位移時程,以帶動該主動桿10同時朝X軸向與Y軸向位移,即可驅動該主動桿10繞著該軸線L進行螺旋狀漸擴軌跡的移動。
Please continue to refer to Figs. 4-7. When the present invention composed of the above-mentioned structure actually performs the lens rubber kneading operation, the
而在該主動桿10被驅動組60帶動進行上述螺旋狀漸擴軌跡的移動時,由於該連動桿20的上端係以萬向接頭結構11樞接於該主動桿10之底端,而位在該連動桿20下端的第一鏡片34又相對抵接於該第二鏡片46上,使該主動桿10於進行上述螺旋狀漸擴軌跡的移動時,樞設於該主動桿10底端的連動桿20也會被該主動桿10所牽引,而同樣可繞著該軸線L進行螺旋狀漸擴軌跡的樞擺偏移,並藉此使位於該連動桿20下端鏡片吸盤30所吸附的第一鏡片36,在繞行該軸線L廻轉的過程中即會同步沿著該第二鏡片46的圓周產生螺旋狀漸擴軌跡的推擠力道,進而使該第一鏡片36會由內而外對該第二鏡片46產生一確實的搓揉作用,使黏膠可被均勻塗抹於第一鏡片36與第二鏡片46的交界面處,同時藉由沿著螺旋狀漸擴軌跡的推擠,使黏膠內的氣泡更可由內而外地被推擠而完全排出。When the
而在上述鏡片揉膠過程結束後,先停止該第一吸氣單元35之作動,以解除該第一吸氣孔33的真空吸附狀態,接著該驅動組60之第一滑動件61再帶動該主動桿10與該連動桿20沿Z軸向上移,使該鏡片吸盤30能夠與該第一鏡片36分離,而後停止該第二吸氣單元之作動,以解除該第二吸氣孔43的真空吸附狀態,即可取下完成揉膠作業後的第一鏡片36與第二鏡片46。總結來說,本發明所提供之鏡片揉膠裝置不但可以自動化方式將黏膠均勻地塗抹於兩鏡片的交界面,且進一步使黏膠內的氣泡可被完全排出,因此具有可確實進行揉膠動作,並同時保有製作效率高的優點。After the above-mentioned lens kneading process is completed, the operation of the
再者,本發明在前述的揉膠過程中,更藉由該氣壓缸54向上頂撐該基板51,且氣壓缸54本身具有一緩衝裕度的特性,因此即使該第一鏡片36受該連動桿20帶動,而對該第二鏡片46產生螺旋狀漸擴軌跡的推擠時,仍可確保該第二鏡片46與該第一鏡片36的緊密貼合,使該第一鏡片36在揉膠過程中能持續與該第二鏡片46接觸,以確保其揉膠過程可順利進行。Furthermore, in the aforementioned rubber kneading process of the present invention, the
