1277452 九、發明說明： 【發明所屬之技術領域】 本發明與一種點膠狀態之診斷+統有關，特別是與 一種應用於封裝印刷電路板之點膠狀態的品質診斷系 統有關。 【先前技術】1277452 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a diagnostic state of a dispensing state, and more particularly to a quality diagnostic system for dispensing a dispensing state of a printed circuit board. [Prior Art]
在封裝印刷電路板（PCB)時常常需要大範圍地塗 佈膠黏劑，以貼合各.層板。為了提高生產速率並增加量 率，多半使用點膠機來進行此項工作。然而，點膠機針 頭的小孔常常因為膠内雜質、乾膠硬塊、氣泡或點膠壓 力不當……等等因素，以致使點膠之品質不穩定，進而 影響點膠機台之良率。為了有效降低生產之成本，有需 要監視點膠品質之衰退狀況，使系統或操作員可以適時 作最佳之調整，以確保生產之良率。 早期都是由操作員在線上直接以目視判斷點膠的 品質。人工目視雖然可以判斷顯著之點膠品質不良，然 而點膠品質之細微瑕疵以及逐漸衰減，則很難以肉眼直 接察覺；等到發生明顯異常時，已經來不及處理，造成 批次生產之工件成為不良品，這種情況在大尺寸的面板 塗膠尤其容易發生，因為大尺寸的面板點膠距離較長， 往往剛開始點膠時，以肉眼判斷尚可，但卻可能點膠到 最後時產生不良狀況。 為了達到監控點膠品質之目的，如美國專利第 4,096,433號、第5,322,706號以及中華民國公告第 513792號專利，分別提出不同的自動化方式取代人工 目視，以監控點膠品質，包括量測塗佈之膠黏劑之重 量、記錄塗佈之膠面高度或是檢測吐膠時點膠機所產生 之聲音訊號等等。 1277452 例如，中華民國公告第513792號專利揭露了一種 封裝點膠系統，該點膠系統在烘烤裝置之後增加一測厚 裝置，以該測厚裝置即時檢測每個產品在供烤後之總厚 度。同時該總厚度之量測值可由系統之控制核心判定是 否符合生產規格，並決定繼續執行或停止相關的製程動 作。When packaging printed circuit boards (PCBs), it is often necessary to apply a wide range of adhesives to fit the layers. In order to increase the production rate and increase the volume, most of the dispensers are used for this work. However, the small holes of the dispenser needle are often caused by impurities in the glue, dry lumps, bubbles or improper pressure of the dispensing, etc., so that the quality of the dispensing is unstable, which in turn affects the yield of the dispensing machine. In order to effectively reduce the cost of production, it is necessary to monitor the deterioration of the quality of the dispensing, so that the system or operator can make the best adjustments at the right time to ensure the yield of production. In the early days, the quality of the dispensing was visually judged directly by the operator on the line. Although manual visual inspection can judge the poor quality of the dispensing, the fineness of the dispensing quality and the gradual attenuation are difficult to detect directly by the naked eye; when the abnormality occurs, it is too late to process, resulting in the batch production of the workpiece becomes a defective product. In this case, it is particularly easy to apply a large-sized panel glue because the large-sized panel has a long dispensing distance, and it is often judged by the naked eye when the dispensing is started, but it may cause a bad condition at the end of dispensing. In order to achieve the purpose of monitoring the quality of dispensing, such as U.S. Patent Nos. 4,096,433, 5,322,706 and the Republic of China Announcement No. 513792, different automated methods are proposed instead of manual visual inspection to monitor the quality of dispensing, including measurement coating. The weight of the adhesive, the height of the coated rubber surface, or the sound signal generated by the dispenser when detecting the glue. 1277452 For example, the Republic of China Publication No. 513792 discloses a package dispensing system that adds a thickness measuring device after the baking device to instantly detect the total thickness of each product after being baked. . At the same time, the measured value of the total thickness can be determined by the control core of the system to meet the production specifications, and it is decided to continue or stop the relevant process operation.
然而這些技術並不太合適用於較濃稠的膠塗布於 大尺寸面板的工作之上。例如有些膠因為是半透明狀 態，若以雷射測量膠的高度，將遇到透光的問題，使檢 測費用過高。而檢測每滴吐膠量之重量之方式，測量些 微重量變化之差異需要較高之靈敏度與準確度，也不太 適合應用在大尺寸LCD面板之連續塗佈之狀況。 職是之故，申請人鑑於習知技術中所產生之缺失， 乃經悉心試驗與研究.，並一本鍥而不捨之精神，終構思 出本發明之「點膠狀態之診斷系統及方法」，以下為本 發明之簡要說明。 【發明内容】 本發明係提供一種點膠狀態之診斷系統，以解決點 膠品質逐漸下滑不易察覺之問題，並透過診斷預警之方法降低 點膠之不良率。 本發明係提供一種點膠狀態之診斷系統，係應用於 具有一膠體儲存裝置的一點膠裝置，該診斷系統包括： 一第一影像擷取裝置，：用於擷取該點膠裝置於點膠過程 的一第一膠體影像；至少一壓力感測器，用於偵測該點 膠裝置及該膠體儲存教置的壓力數據；以及一系統主 機，用於接收並分析所擷取之該第一膠體影像及所偵測 之壓力數據。 較佳者，該第一膠體影像包括該膠體之寬度。 1277452 較佳者，該第一膠體影像包括上視圖相似度之影像。 較佳者，該系統更包括一第二影像擷取裝置，其設置 於該點膠裝置之侧面，用於擷取一第二膠體影像。 較佳者，該第二膠體影像包括該膠體之厚度。 較佳者，該第二膠體影像包括侧視圖相似度之影像。 較佳者，該系統更包括一控制氣壓管路，用以調控該 點膠裝置及該膠體儲存裝置。 .一一 較佳者，該壓力感測器係設置於該控制氣壓管路上， 以偵測壓力數據。However, these techniques are not well suited for the application of thicker gels to large-sized panels. For example, some glues are translucent. If the height of the glue is measured by laser, the problem of light transmission will be encountered, which will make the inspection cost too high. The way to measure the weight of each drop of glue is to measure the difference in micro-weight changes that require higher sensitivity and accuracy, and is less suitable for continuous coating of large-size LCD panels. For the sake of the job, the applicant has carefully tested and researched the shortcomings in the prior art, and has carefully developed the "diagnostic system and method for dispensing state" of the present invention. This is a brief description of the invention.

Using different calculation methods, the diagnostic system of the present invention can cross-align the recorded colloidal images and pressure data to establish the characteristics of the dispensing condition, so that the health confidence index CV value of the dispensing quality at any time point can be diagnosed ( Step 108): CV=f(V,P) In the diagnostic method of the present invention, the health confidence index of the dispensing quality is represented by the CV value, for example, the normal health state is represented by 1, and the health state is degraded by the numerical value. The V value represents the dispensing characteristic value obtained from the colloidal image; and the P value represents the pressure comprehensive characteristic value of the dispensing condition. Algorithms for calculating the diagnostic methods of the present invention include, but are not limited to, a neurological system, a fuzzy logic, or an expert system. The system host 24 will display the diagnosed dispensing health status, as shown in step 109 on the display screen of the host for reference by the user, and when the dispensing health status is degraded, the system host 24 will automatically issue a diagnostic report, for example, the air pressure should be adjusted. Pressure, adjust the glue gun adjustment button, and / or should replace the needle, and actively use the warning message to alert the user to the abnormal phenomenon (step 110). The type of warning message can be sound, flash, chart, email or mobile phone newsletter.
12 1277452 透過本發明之診斷系統可以有效地預測點膠針頭 的壽命，本發明之診斷系統並會在最適當的時間，主動 提醒操作員對點膠針頭、點膠氣壓壓力或點膠槍作適當 的調整或更換。經由本發明之點膠品質診斷系統之監控 以及預先告知，可以減少不良品之發生，並可達到最佳 的機台效率，避免不適當或過早的調整而浪費生產的時 間或費用，同時因為本發明之診斷系統可以自動監視點 膠的品質，使操作員可以有更多時間照顧生產線上其他 工作。12 1277452 The life of the dispensing needle can be effectively predicted by the diagnostic system of the present invention, and the diagnostic system of the present invention actively reminds the operator to properly dispense the dispensing needle, the dispensing pressure or the dispensing gun at the most appropriate time. Adjustment or replacement. Through the monitoring and pre-notification of the dispensing quality diagnostic system of the present invention, the occurrence of defective products can be reduced, and the optimal machine efficiency can be achieved, and the time or expense of production can be wasted by avoiding inappropriate or premature adjustment, and because The diagnostic system of the present invention automatically monitors the quality of the dispensing, allowing the operator more time to take care of other tasks on the production line.
