201249544 六、發明說明： 【發明所屬之技術領域】 本發明涉及一種具排氣泡之點膠裝置，可將膠體容置室内 之氣泡排除，且具有能防止推動柱塞於膠體容置室内滑行時被 膠水内之添加物粉粒卡住。 【先前技術】 目前常見之點膠裝置主要應用於各種電子晶片、光學鏡頭 以及LCD、LED之組裝時進行點膠，隨著科技技術的進步，電 子元件越做越小，因此需要高精度之點膠裝置進行點夥，其大 概區分為喷射點膠方式與針頭點膠方式，以進行最精確位置之 塗佈’上述之習知技藝為業界所普遍採用，例如我國公告第 M246506號、第590049號以及美國專利第US6371339號第 US7762088號。 目前點膠裝置之膠水點膠方式技藝常用柱塞推動膠水從 膠體容置室内排出，並由控制系統控制驅動模組以進行柱塞最 準確之移動，利用膠體容置室容積之改變控制膠水流出量或壓 力；為求品質良好，必須精確控制點膠壓力、點膠量大小等， 惟該種點膠裝置更換儲膠筒時會造成膠水管路間殘留之空氣 進入點膝裝置’因而常發生膠水中有氣泡，使得點膠過程；出 見點膠量大小不-’甚至，造成產品沒有點膠之缺失因而產 品不良率提高；另外，目前膠水中常需要加入勞光粉或各種添 加劑等粉粒混合，例如LED之點膠作業，該種螢光粉為細小粉 粒狀混於膠水中，會滲人推動柱塞與膠體容置室之牆壁兩者間 之細縫’造成推動柱塞與膠體容置室卡住無法使用，甚至因而 造成機器損壞。 201249544 如第1A圖與第1B圖所示為一習知點膠裝置，該習知點膠 裝置具有一儲膠筒300、一注膠筒4〇〇以及一切換閥裝置， 切換閥裝置500中具有一驅動器5〇1以及第一通道5〇2、第二通 道503，一推動柱塞4〇1深入該注膠筒4〇〇内之膠水容置室扣2， 一點膠針頭600裝於注膠筒4〇〇下方，第1A圖為傳統點膠裝置 之膠水從儲膠筒300進入該注膠筒4〇〇之剖視圖，此時切換閥裝 置500之第二通道5〇3連通儲膠筒3〇〇與注膠筒4〇〇，如儲膠筒 300更換，或者第一次使用時，膠水通道或注膠筒4〇〇内殘留空 氣會與膠水混合形成氣泡404進入注膠筒4〇〇，需進行排氣泡作 業，第1B圖為習知點膠裝置氣泡4〇4或膠水5〇從注膠筒*⑽排出 點膠針頭600之剖視圖，此時切換閥裝置5〇〇之第一通道連 通注膠筒400與與點膠針頭600，由於注膠筒4〇〇之排膠口 4〇3 位於底部，而氣泡404比重較輕會自行往上升於膠水容置室4〇2 頂部，而不會從排膠口 403以及出膠口 6〇1排出；使得氣泡4〇4 之排出作業不順利，停留於膠水容置室4〇2内或膠水通道中， 縱使推動柱塞401降至膠水容置室4〇2之底部，兩者間之小空隙 以及膠水通道中仍會停留氣泡4〇4，以至無法完全乾淨排除氣 泡404 ;再者，推動注塞4〇1與膠水容置室4〇2内壁兩者為緊密 接合以便滑行推動膠水50排出點膠，膠水5〇中如加入添加劑或 螢光粉等粉粒405，滑行過程及壓力作用下，粉粒4〇5會滲入推 動柱塞401與容置室402牆壁兩者間之細縫4〇6，造成推動柱塞 401卡住’無法繼續動作，甚至造成損壞，必須更換。 由此可知，習知點膠裝置仍存在上述所述諸多缺失，而有 予以改進之必要。 【發明内容】

固定於機座立柱142。 在此，本文先針對驅動模組110、點膠模組120以及切換模 組130之組成構件及其構件間之連接關係做說明。在本實施例 中’驅動模組110係包括一驅動單元112與一推動柱塞U4,驅 動單元112適於驅動推動柱塞114移動。驅動單元112設於基座 140内，驅動單元112例如是伺服馬達或步進馬達所驅動而於基 座立柱142上直線上下滑移，其由控制系統控制其做精密作 動，以帶動推動柱塞114進行例如是直線上下之移動《此外， 點膠模組120則包括一本體122、一設置於本體122之膠體容置 室124、一設置於本體122之進膠通道126以及一設置於本體122 10 201249544 之出膠通道128。進膠通道126以及出膠通道128係為設置於本 體122内’但互為分開獨立之二通道。 此外，本實施例之出膠通道128係設於膠體容置室124側 邊’出膠通道128之延伸方向係與推動柱塞114之移動方向相互 平行。本體122具有一進膠口 122a以及一出膠口 122b，進膠通 道126之一端是連通於膠體容置室i24之一開口，開口設置於膠 體容置室124適當地方，本實施例該開口為位於膠體容置室124 下方之一下方開口 124a，進膠通道126之另一端則是連通於進 膠口 122a。另一方面，出膠通道128之一端是連通於膠體容置 室124之一上方開口 124b，出膠通道128之另一端則是連通於出 膠口 122b。 在本實施例中，點膠裝置100更可包括一用以儲存膠水50 之儲膠筒150。此外，點膠裝置1〇〇還設有一端連通出膠口 122b ’另一端連通一點膠針頭ι6〇之一轉接頭17〇。亦即，本實 施例之出膠口 122b係連接轉接頭17〇,而轉接頭no係再連接點 勝針頭160。另外，本實施例之儲膠筒ι5〇係可以更換的方式連 接於本體122之進膠口 122a’而儲膠筒150内之膠水5〇係能由進 膠口 122a經進膠通道126自膠體容置室ι24之下方開口 12乜注 入膠體容置室124’再由膠體容置室124之上方開口以朴流經出 膠通道128而自本體122之出膠口 i22b排至點膠針頭16〇，以進 行點膠作業或排氣泡作業。再者，為方便該些膠體所流經之通 道的β潔作業，本實施例例如還設有一連接進膠通道126之一

的區段）以及一第二部分進膠通道126b(第一連通道132d另一 端至膠體容置室124之下方開口 124a的區段）。 承上所述，為讓第一切換單元132能有效地控制膠水於進 膠通道126之流通’本實施例即是將第一切換閥132a設於進膠 13 201249544 通道126之一轉折處’以減緩膠水流動之衝擊，進而能有效地 控制進入膠體容置室124之膠水量。詳細地說，第一部分進膠 通道126a的延伸方向即例如與第二部分進膠通道126b的延伸 方向相平行，而第一部分進膠通道126a的延伸方向以及第二部 分進膠通道126b的延伸方向即例如與第一連通道丨32d的延伸 方向相互垂直’再加上第一連通道132d之延伸方向例如與第一 切換閥驅動桿132b之作動方向相互垂直，因此藉由第一切換閥 驅動桿132b之作動能讓第一切換閥132a於二部分之進膠通道 間控制膠水之流通。 同樣地’第二切換單元134例如是由一第二切換閥134a、 一第二切換閥驅動桿134b以及一第二切換閥驅動器134c所組 成。第二切換閥驅動器134c亦例如是由氣體推動之氣壓缸或是 電動閥，而第一切換閥驅動桿132b之作動方向例如是與第二切 換閥驅動桿134b之作動方向相互平行。其中，第二切換閥134a 例如設有一第二連通道134d，第二連通道I34d之延伸方向例如 與第二切換閥驅動桿134b之作動方向相互垂直，第二連通道 134d係分別與出膠口 122b以及膠體容置室124之上方開口 124b 相通。藉由第二連通道134d之設置來將出膠通道128劃分為一 第一部分出膠通道128a(膠體容置室124之上方開口 124b至第 二連通道134d—端的區段）以及一第二部分出膠通道i28b(第 二連通道134d另一端至出膠口 122b的區段）。 與第一切換單元132之設置目的相同，為讓第二切換單元 134能有效地控制膠水於出膠通道128之流通，本實施例係將第 二切換閥134a設於出膠通道128之一轉折處，以減緩膠水流動 之衝擊，進而能有效地控制點膠作業膠水量。詳細地說，第一 部分出膠通道128a的延伸方向例如與第二部分出膠通道i28b 的延伸方向相垂直，而第一部分出膠通道128a的延伸方向例如 201249544 與第二連通道134d的延伸方向相互平行，再加上第二連通道 134d之延伸方向例如與第二切換閥驅動桿134b之作動方向相 互垂直’因此藉由第二切換閥驅動桿134b之作動能讓第二切換 閥134a於二部分之出膠通道間控制膠水之流通。 如此一來’本實施例之第一切換閥驅動器132c即適於驅動 第一切換閥驅動桿132b來開啟或是關閉第一切換閥132a(或第

Description of the Invention: [Technical Field] The present invention relates to a dispensing device with a bubble exhausting device, which can remove the air bubbles in the colloidal accommodation chamber and has the function of preventing the pushing plunger from sliding in the colloid housing chamber It is stuck by the additive powder in the glue. [Prior Art] At present, the common dispensing device is mainly used for dispensing various electronic wafers, optical lenses, and LCDs and LEDs. With the advancement of technology, electronic components are getting smaller and smaller, so high precision is required. The glue device performs the point-of-sale, which is roughly divided into the spray dispensing method and the needle dispensing method for the most precise position coating. The above-mentioned conventional techniques are commonly used in the industry, for example, China Bulletin No. M246506, No. 590049 And U.S. Patent No. 6,371,339, U.S. Patent No. 7,762,088. At present, the glue dispensing method of the dispensing device is generally used to push the glue out of the colloid housing chamber, and the control system controls the driving module to perform the most accurate movement of the plunger, and controls the glue outflow by using the volume change of the colloidal housing chamber. Quantity or pressure; in order to achieve good quality, it is necessary to precisely control the dispensing pressure, the amount of dispensing, etc., but when the dispensing device replaces the storage cartridge, the residual air between the glue lines will enter the knee device. There are air bubbles in the glue, which makes the dispensing process; the amount of glue is not found in the '- even the product does not have the lack of dispensing and the product defect rate is improved; in addition, the glue often needs to add the light powder or various additives and other powders.

For example, the dispensing module 120 includes a body 122, a glue receiving chamber 124 disposed on the body 122, a feeding passage 126 disposed in the body 122, and a body 122. 10 201249544 The glue outlet channel 128. The glue passage 126 and the glue passage 128 are two passages disposed in the body 122 but separated from each other. In addition, the dispensing passage 128 of the present embodiment is disposed on the side of the colloidal accommodating chamber 124. The extending direction of the dispensing passage 128 is parallel to the moving direction of the pushing plunger 114. The body 122 has a rubber inlet 122a and a rubber outlet 122b. One end of the rubber passage 126 is connected to one of the openings of the gel housing chamber i24. The opening is disposed at a suitable position of the gel housing chamber 124. Located at a lower opening 124a below the colloidal accommodation chamber 124, the other end of the feed passage 126 is in communication with the feed port 122a. On the other hand, one end of the dispensing passage 128 is communicated with one of the upper openings 124b of the gel containing chamber 124, and the other end of the dispensing passage 128 is communicated with the dispensing opening 122b. In this embodiment, the dispensing device 100 further includes a plastic cartridge 150 for storing the glue 50. In addition, the dispensing device 1 has a one end connected to the rubber port 122b' and the other end is connected to a rubber needle head ι6〇 one of the joints 17〇.

At this time, the water I is pumped 50 is lighter [and therefore bubbles. Since the bubble 50a is not able to be dispensed when the colloidal valley is set to 124, the bubble discharge operation is required first. The fifth drawing shows the operation of the switching module of the second AgJ in the bubble discharging operation, and the fifth drawing shows the enlarged view of the R region of the fifth drawing. Please refer to FIG. 5A and FIG. 5B'. During the bubble discharging operation, the control system controls the first switching unit 132 to block the glue passage 126, and the second switching unit 134 opens the glue passage 128' and controls The system control driving unit 112 pushes the plunger ι 4 into the colloidal accommodating chamber 124 to move downward, so that the bubbles or glue 'in the colloid accommodating chamber 124' is discharged by the dispensing passage 128 for the venting operation. In detail, during the bubble discharging operation, the first switching valve driver 132c drives the first switching valve driving lever 132b to act on the first plunger 132e, causing the first plunger 13 to close the first switching valve 132a. (or the first connecting passage 132d), the first partial feeding passage n6a and the first partial feeding passage 126b are blocked by the first switching valve 1323 to be in a non-conducting state, preventing the glue in the colloidal accommodation chamber 124 from flowing back to the storage. The inside of the rubber cylinder 15 caused the bubble discharge operation to be unsmooth. 16 201249544 relatively 'the second switching valve driver 134c will drive the second switching valve drive rod 134b to act on the second plunger 134e, causing the second plunger l34e to open the second switching valve 134a (or the second connecting passage 134d), The first portion of the glue outlet channel 128a and the second portion of the glue outlet channel 128b are in a connected state. At this time, the control system controls the driving module 110 to be activated to cause the pushing plunger 114 to be pressed down, and the air bubbles 50a above the colloidal accommodation chamber 124 and the air bubbles 50a in the dispensing passage 128 are passed through the glue outlet channel 128 and the glue outlet. The 122b and the dispensing needle 160 are discharged until the glue 50 is completely discharged. In the present invention, the specific gravity of the bubble 5〇a is lighter than that of the glue 50, so that the bubble 50a is automatically ejected from the discharge passage 128 to ensure that the bubble 5〇a is completely discharged from the dispensing module 120. After performing the bubble discharging operation as shown in FIGS. 5A and 5B, since the bubble 50a is absent, the dispensing operation can be performed (as shown in FIG. 5C, which shows the switching module of FIG. 2A). Schematic diagram of the operation of the dispensing operation). In FIG. 5C, the first switching valve driver 132c continuously drives the first switching valve drive lever 132b to act on the first plunger 132e, causing the first plunger i32e to close the first switching valve 132a (or the first connecting passage 132d). . Similarly, the second switching valve actuator 134C continues to drive the second switching valve actuating lever 134b to act on the second plunger 134e, causing the second plunger 134e to open the first switching valve 134a (or the second connecting passage 134d). At the same time, the driving module 110 can be activated to cause the pushing plunger 114 to be pressed down, and the glue 50 in the colloidal receiving chamber 124 can be discharged through the dispensing passage 128, the dispensing opening 122b and the dispensing needle 160. Due to the adverse effect of the presence of the bubble 5〇a, when the control driving module 110 drives the push plunger 114 to perform precise displacement, the precise dispensing amount can be ensured to effectively achieve the dispensing operation. 6A is a schematic view showing a dispensing device according to another embodiment of the present invention, FIG. 6B is a partial enlarged view of FIG. 6A, and FIG. 6C is an enlarged view of a R region of FIG. 6B. Please refer to FIG. 6A, FIG. 6B and FIG. 6C. The dispensing device 200 of the present embodiment is similar to the dispensing device 100 of the above embodiment, but the difference between the two is 17 201249544. The difference is that the dispensing device of the embodiment The switch module no uses a film 136 to replace the first plunger 132 of the first switching unit 132 with the first elastic member 132f and the second plunger 134e of the second switching unit 134. And the second elastic member 134f to open or block the first connecting passage I32d and the second connecting passage 134d. In detail, in this embodiment, the film 136 is disposed in the first connecting passage i32d and the second connecting passage 134d, and the first switching valve driving rod 132b is adapted to press the film 136 to block the first connecting passage 132d'. The lower opening 124a of the colloidal accommodating chamber 124 is not in communication with the feeding port 122a, and the second switching valve driving rod 134b is adapted to press the film 136 to block the second connecting passage 134d, so that the upper opening 124b of the colloidal accommodating chamber 124 It is not connected to the glue outlet 122b. Wherein, since the film 136 has elastic deformation characteristics, when the first switching valve driving rod 132b no longer presses the thin 臈136 or the second switching valve driving rod 134b no longer presses the film 136, the film 136 will borrow itself. The elastic restoring force is restored to the original state, and the first connecting passage 132d or the second connecting passage 134d' is not blocked to perform the feeding operation as shown in FIGS. 7A and 7B (Fig. 7A is a diagram showing Fig. 6A) The switching module is shown in the operation diagram of the feeding operation, and FIG. 7B is an enlarged view of the R region in the seventh drawing. In the state shown in FIGS. 7A and 7B, the first switching valve actuating lever 132b does not press against the film 136' so that the glue in the cartridge 150 can flow through the glue passage 126 and be injected into the gel housing chamber. In the 124, the second switching valve driving rod 134b presses the film 136, so that the rubber discharge passage 128b is blocked by the second switching valve 134a to be in a non-conducting state, so as to facilitate the rubber feeding operation. After performing the feeding operation as shown in FIGS. 7A and 7B, the present embodiment can also perform the bubble discharging operation shown in FIGS. 5A and 5B as in the above embodiment and shown in FIG. 5C. Dispensing operation. Fig. 8A is a schematic diagram showing the operation of the switching module of the embodiment in the dispensing operation, and Fig. 8B is an enlarged view of the R region of Fig. 8A. In the state shown in FIGS. 8A and 8B, the first 201249544 switching valve actuating lever 132b presses against the film 136, so that the glue in the cartridge 15 can no longer flow through the glue passage 126 to be injected into the gel. In the chamber 124, the second switching valve driving rod 134b no longer presses the film 136, so that the dispensing passage 1281) is in a conducting state, so as to facilitate the dispensing operation. As for the bubble discharging operation of the embodiment, since the dispensing process is performed before the dispensing operation, the main components are operated in the same manner as the dispensing operation shown in Figs. 8A and 8B, and the bubble discharging principle is also The contents of the description corresponding to the bubble-removing operation shown in Fig. 5 and Fig. 5B are explained, and therefore will not be described herein. In summary, the dispensing device of the present invention has an upper opening above the gel receiving chamber and communicates with the rubber passage, so that the bubble in the glue water can automatically rise and discharge therefrom, thereby achieving the function of easily eliminating bubbles completely, and further providing Accurate dispensing, improve product quality yield in dispensing operations. At the same time, the dispensing device of the present invention pushes the outer diameter of the plunger slightly smaller than the inner diameter of the colloidal accommodation chamber, and pushes the outer diameter of the plunger and the inner diameter of the colloid to have an appropriate gap, thereby avoiding pushing the plunger and the colloidal accommodation chamber. The squeezing of the squeegee into the glue or the powder of the phosphor powder causes the jam to be unable to move or be damaged, thereby reducing the loss of interrupting the repair or replacement. In addition, the present invention utilizes the first switching unit and the second switching. The switching valve of the unit has a short stroke, which can quickly change the hand-in operation and the point-crossing operation, and improve the speed of the point-crossing operation. Therefore, the invention has the advantages of easily eliminating bubbles, not easily changing, improving the product, dispensing quality and increasing production speed. And so on, it is indeed possible to achieve the object of the present invention. The above-described embodiments are merely examples for convenience of description, and the scope of the invention is not limited thereto. The scope of the claims of the invention is based on the scope of the patent application, and is not limited to the above embodiments.
