Description
本發明係與冷陰極放電燈管之製作方法有關，特別是關於一種無接痕大直徑冷陰極放電燈管之加工製作方法。The invention relates to a method for manufacturing a cold cathode discharge lamp tube, in particular to a method for processing a non-contact large-diameter cold cathode discharge lamp tube.
於典型的冷陰極放電燈管中，電極的導線上通常被封著一玻璃珠，用以熔接於玻璃管，使電極被固定於玻璃管的兩端，以形成冷陰極管。然而，玻璃珠的尺寸大小有一定的限制，使得其所對應之玻璃管直徑也受到限制。因此，前述冷陰極放電燈管尺寸相對較小，其玻璃管直徑通常無法超過3mm。這樣的冷陰極放電燈管照度相對較低，只適用於液晶顯示器的背光光源，無法用於需要高照度的照明用具。若勉強用於高照度的照明用具，則需要大量的小尺寸冷陰極放電燈管並列設置，使得整個照明用具電路配置及實體結構顯得複雜。In a typical cold cathode discharge lamp, the wire of the electrode is usually sealed with a glass bead for welding to the glass tube, so that the electrode is fixed to both ends of the glass tube to form a cold cathode tube. However, the size of the glass beads is limited, so that the diameter of the corresponding glass tube is also limited. Therefore, the aforementioned cold cathode discharge lamp has a relatively small size, and the diameter of the glass tube generally cannot exceed 3 mm. Such a cold cathode discharge lamp has a relatively low illuminance and is only suitable for a backlight source of a liquid crystal display, and cannot be used for a lighting fixture requiring high illumination. If it is barely used for high-illumination lighting fixtures, a large number of small-sized cold cathode discharge lamps are required to be juxtaposed, so that the circuit configuration and the physical structure of the entire lighting fixture are complicated.
傳統的放電燈管中，雖然存在尺寸相對較大者，例如霓虹燈管。霓虹燈管之製作方法係先將電極固定於一小段短玻璃管中，再將前述的短玻璃管融接在長玻璃管的兩端，形成尺寸相對較大(大直徑、大長度)之放電燈管。但是這樣的霓虹燈管存在者技術問題。第一、前述之短玻璃管融接在長玻璃管的程序，只能透過手工執行，尚無法以機械取代，使得霓虹燈管的生產效率不佳，而無法大量地生產。第二、短玻璃管融接在長玻璃管的兩端，會形成明顯的接痕，這樣的接痕影響美觀，同時也可能造成應力強度不足的問題。第三、短玻璃管融接在長玻璃管的兩端的程序係由手工執行，因此長玻璃管將受到限制，否則進行手工融接作業之工匠可能會無法順利的進行手工融接作業。因此，前述之霓虹燈管縱使改變填充氣體成分，使其光譜符合一般照明需求，其無法大量地生產的缺點，仍無法使其作為照明用具所需。In conventional discharge lamps, although there are relatively large sizes, such as neon tubes. The method for manufacturing the neon tube is to first fix the electrode in a short short glass tube, and then fuse the short glass tube to the two ends of the long glass tube to form a discharge lamp having a relatively large size (large diameter, large length). tube. But such neon tubes exist technical problems. First, the procedure for the short glass tube to be fused to the long glass tube can only be performed by hand, and it cannot be replaced by mechanical, so that the production efficiency of the neon tube is not good, and it cannot be produced in a large amount. Second, the short glass tube is fused at both ends of the long glass tube, and obvious joints are formed. Such a joint affects the appearance and may also cause a problem of insufficient stress strength. Third, the procedure for the short glass tube to be fused to the ends of the long glass tube is performed manually, so the long glass tube will be limited, otherwise the craftsman who performs the manual fusion operation may not be able to perform the manual fusion operation smoothly. Therefore, the aforementioned neon tube can not be used as a lighting fixture even if it changes the composition of the filling gas so that its spectrum conforms to the general lighting demand, and it cannot be mass-produced.
鑑於習知技術中的冷陰極放電燈管有尺寸過小，或是生產製程之缺點，本發明無接痕大直徑冷陰極放電燈管之加工製作方法，係可採用機械化批量生產大直徑及大長度之冷陰極放電燈管。In view of the fact that the cold cathode discharge lamp tube of the prior art has a small size or a disadvantage of the production process, the method for processing the non-contact large-diameter cold cathode discharge lamp tube of the invention can be mass-produced by large-scale and large-length. Cold cathode discharge lamp.
本發明提出一種無接痕大直徑冷陰極放電燈管之加工製作方法，包含下列步驟：(1)固定一電極，其中電極至少具有一放電杯及連接放電杯之導線；(2)提供一玻璃管，使放電杯通過玻璃管未封口之端部而進入玻璃管中，並固定玻璃管；(3)以至少一火炬完整地對整個玻璃管的外周面加熱，使玻璃管的端部被軟化而進入融熔之狀態；(4)使用一夾具夾持玻璃管之端部，使端部收斂為一體；(5)持續對已被夾持收斂之玻璃管之端部進行加熱，進行回火處理；(6)完成玻璃管之另一端部之封著，以完成無接痕大直徑冷陰極放電燈管；及(7)將無接痕大直徑冷陰極放電燈管置入回火爐中，將整個無接痕大直徑冷陰極放電燈管加熱至回火點溫度，對整個無接痕大直徑冷陰極放電燈管進行回火處理。The invention provides a method for processing a non-contact large-diameter cold cathode discharge lamp, comprising the following steps: (1) fixing an electrode, wherein the electrode has at least one discharge cup and a wire connecting the discharge cup; (2) providing a glass a tube, the discharge cup is passed through the unsealed end of the glass tube into the glass tube, and the glass tube is fixed; (3) the outer peripheral surface of the entire glass tube is completely heated by at least one torch, so that the end of the glass tube is softened And enter the state of melting; (4) use a clamp to clamp the end of the glass tube, so that the end is converged into one; (5) continue to heat the end of the glass tube that has been clamped and tempered (6) completing the sealing of the other end of the glass tube to complete the unattached large diameter cold cathode discharge lamp tube; and (7) placing the unattached large diameter cold cathode discharge lamp tube into the tempering furnace, The entire unattached large diameter cold cathode discharge lamp tube is heated to the tempering point temperature, and the entire unattached large diameter cold cathode discharge lamp tube is tempered.
本發明之無接痕大直徑冷陰極放電燈管之加工製作方法，取代了傳統多段融接的方式，不會在大尺寸燈管二端的形成接痕。且本發明所提出之方法，可以使用機械取代手工，對大直徑且大尺寸之玻璃管進行封口。因此，透過本發明製作方法製作之冷陰極放電燈管，可以廣泛地用於製作大型燈具，使 冷陰極放電燈管更適合應用於照明或是大尺寸顯示單元之背光需求中。The processing method for manufacturing the jointless large-diameter cold cathode discharge lamp of the invention replaces the traditional multi-stage fusion method, and does not form a joint at the two ends of the large-sized lamp tube. Moreover, the method proposed by the present invention can mechanically replace the large diameter and large size glass tube by hand. Therefore, the cold cathode discharge lamp produced by the manufacturing method of the present invention can be widely used for making large lamps, so that Cold cathode discharge lamps are more suitable for use in lighting or backlighting requirements for large display units.
請參閱「第1圖」所示，係為本發明實施例所揭露之一種無接痕大直徑冷陰極放電燈管之加工製作方法，用以將一玻璃管10之端部11密封，並使電極20固定於端部11。前述之電極20至少具有一放電杯21及連接放電杯21之導線22，而玻璃管10之內側壁面則預先塗佈螢光物質，可被紫外線激發而發出可見光。本發明之無接痕大直徑冷陰極放電燈管之加工製作方法，是用於機械量產之大直徑及超長度之冷陰極放電燈管，冷陰極放電燈管之直徑可介於6mm至20mm，且長度可介於1至3.6公尺。Referring to FIG. 1 , a method for processing a non-contact large-diameter cold cathode discharge lamp disclosed in an embodiment of the present invention is used to seal the end portion 11 of a glass tube 10 and The electrode 20 is fixed to the end portion 11. The electrode 20 has at least one discharge cup 21 and a wire 22 connecting the discharge cup 21, and the inner wall surface of the glass tube 10 is coated with a fluorescent substance in advance, and is excited by ultraviolet rays to emit visible light. The method for processing the jointless large-diameter cold cathode discharge lamp tube of the invention is a large-diameter and ultra-long-length cold cathode discharge lamp tube for mechanical mass production, and the diameter of the cold cathode discharge lamp tube can be between 6 mm and 20 mm. And can be between 1 and 3.6 meters in length.
請參閱「第1圖」及「第2圖」所示，本發明實施例之無接痕大直徑冷陰極放電燈管之加工製作方法，係先以一電極治具30固定前述之電極20(步驟10)。Referring to FIG. 1 and FIG. 2, in the method for manufacturing a non-contact large-diameter cold cathode discharge lamp according to an embodiment of the present invention, the electrode 20 is fixed by an electrode fixture 30 ( Step 10).
如「第2圖」所示，通常電極20是被直立地固定，而且放電杯21係朝上。由於放電杯21最後必須放入玻璃管10中，同時導線22的一部份最後也會埋設於玻璃管10封口的端部11中，因此電極治具30通常會夾持固定導線22之末端，使放電杯21及導線22連接放電杯21的部分可以不受到阻礙地進入玻璃管10中。As shown in "Fig. 2", normally, the electrode 20 is fixed upright, and the discharge cup 21 is directed upward. Since the discharge cup 21 must finally be placed in the glass tube 10, and a portion of the wire 22 is finally buried in the end portion 11 of the sealing of the glass tube 10, the electrode fixture 30 usually holds the end of the fixed wire 22. The portion where the discharge cup 21 and the wire 22 are connected to the discharge cup 21 can enter the glass tube 10 without being hindered.
請參閱「第1圖」及「第3圖」所示，接著係由上往下地放置玻璃管10，並使預備封口之端部11朝下，並使放電杯21通過未封口之端部11而進入玻璃管10中(步驟21)，而導線22係局部地位於玻璃管10中，其餘外露於玻璃管10外。當玻璃管到達定位時，並使放電杯21位於玻璃管10中時，就可以透過一玻璃管治具40固定玻璃管10(步驟22)。Referring to "Fig. 1" and "Fig. 3", the glass tube 10 is placed from top to bottom with the end portion 11 of the preliminary seal facing downward, and the discharge cup 21 is passed through the unsealed end portion 11 While entering the glass tube 10 (step 21), the wire 22 is partially located in the glass tube 10 and the remainder is exposed outside the glass tube 10. When the glass tube reaches the position and the discharge cup 21 is placed in the glass tube 10, the glass tube 10 can be fixed through a glass tube fixture 40 (step 22).
一般而言，玻璃管治具40通常包含上夾持具31及下夾持 具32，分別夾持於玻璃管10之不同位置。以用於製作無接痕大直徑冷陰極放電燈管的機台而言，機台可以同時包含多個電極治具及玻璃管治具，使同時固定多個玻璃管，並使各玻璃管直立地排列為一直線或是環狀，以同時或依序對多個玻璃管進行加工，以對無接痕大直徑冷陰極放電燈管進行批量化生產。In general, the glass tube fixture 40 typically includes an upper clamp 31 and a lower clamp. The holders 32 are respectively clamped at different positions of the glass tube 10. For a machine for making a large-diameter cold-cathode discharge lamp without a trace, the machine can include a plurality of electrode fixtures and a glass tube fixture at the same time, so that a plurality of glass tubes are fixed at the same time, and the glass tubes are erected at the same time. The ground is arranged in a straight line or a ring shape to process a plurality of glass tubes simultaneously or sequentially to mass-produce the unattached large diameter cold cathode discharge lamps.
請參閱「第1圖」及「第4圖」所示，接者以二組火炬50，面對面地由玻璃管10二側對玻璃管10之端部11加熱，將玻璃管10之玻璃材料加熱至軟化並接近融熔狀態(步驟30)。此時，由於玻璃材料之內聚特性，玻璃管10之端部會略微內縮為錐狀。但在玻璃管10之直徑超過6mm時，玻璃材料之內聚仍不足以使玻璃管10之端部11自動密封。兩組火炬50係具備複數個排列為一直線之噴火口，且噴火口係沿著玻璃管10之徑向排列。相對之二組火炬50係可以完整地對整個玻璃管10的外周面加熱，使玻璃管10的端部11被軟化而進入融熔之狀態。Please refer to "Figure 1" and "Figure 4". The two sets of torches 50 are used to heat the glass material of the glass tube 10 by heating the glass material of the glass tube 10 from the two sides of the glass tube 10 to the surface. To soften and approach the molten state (step 30). At this time, due to the cohesive property of the glass material, the end portion of the glass tube 10 is slightly contracted into a tapered shape. However, when the diameter of the glass tube 10 exceeds 6 mm, the cohesion of the glass material is still insufficient to automatically seal the end portion 11 of the glass tube 10. The two sets of torches 50 have a plurality of blast ports arranged in a line, and the blast ports are arranged along the radial direction of the glass tube 10. The two sets of torches 50 can completely heat the outer peripheral surface of the entire glass tube 10, so that the end portion 11 of the glass tube 10 is softened and enters a molten state.
請參閱「第1圖」及「第5圖」所示，當玻璃管10之端部11已經充分軟化且呈現融熔狀態時，使用一夾具60夾持玻璃管10之端部11，使端部11收斂為一體，以密封玻璃管10之端部11，並將導線22之部分包覆於玻璃管10之玻璃材料中(步驟40)。Referring to "Fig. 1" and "Fig. 5", when the end portion 11 of the glass tube 10 has been sufficiently softened and in a molten state, the end portion 11 of the glass tube 10 is held by a jig 60 so that the end The portion 11 converges integrally to seal the end portion 11 of the glass tube 10 and enclose a portion of the wire 22 in the glass material of the glass tube 10 (step 40).
請參閱「第1圖」及「第6圖」所示，接著再以二組火炬50持續對已被夾持收斂玻璃管10之端部11進行加熱，進行回火處理(thermal tempering)(步驟50)。回火處理用以再度將玻璃管10之至少端部11區域的溫度再度加熱至回火點溫度，以消除玻璃管10在前一步驟之夾持工序中產生的內應力，使內外應力達到平衡，避免端部11受到微小外力衝擊就發生破裂。Referring to the "Fig. 1" and "Fig. 6", the end portions 11 of the clamped astringent glass tube 10 are continuously heated by the two sets of torches 50, and tempering is performed (step tempering). 50). The tempering treatment is used to reheat the temperature of at least the end portion 11 of the glass tube 10 to the tempering point temperature to eliminate the internal stress generated by the glass tube 10 in the clamping step of the previous step, so that the internal and external stresses are balanced. The end portion 11 is prevented from being broken by a slight external force.
當一端部10之封口作業完成之後，則需要再度將玻璃管 10反置，重複前述步驟(步驟10至步驟50)，完成另一端部11之封口及電極固定的作業，完成兩端部11之封口之後，就可以完成無接痕大直徑冷陰極放電燈管之製作。When the sealing operation of the end portion 10 is completed, the glass tube needs to be re-applied. 10 is reversed, repeating the foregoing steps (steps 10 to 50), completing the sealing of the other end portion 11 and fixing the electrode, and completing the sealing of the both end portions 11, the large-diameter cold cathode discharge lamp tube without connection is completed. Production.
參閱「第1圖」及「第7圖」所示，最後將完成無接痕大直徑冷陰極放電燈管置入回火爐70中，將整個無接痕大直徑冷陰極放電燈管加熱至回火點溫度，對整個無接痕大直徑冷陰極放電燈管進行回火處理(步驟60)，以消除整個玻璃管10因為封口作業產生之內應力，提升玻璃管10之強度。Referring to "Figure 1" and "Figure 7", the unattached large-diameter cold cathode discharge lamp is finally placed in the tempering furnace 70 to heat the entire non-contact large-diameter cold cathode discharge lamp to the back. At the fire point temperature, the entire non-contact large-diameter cold cathode discharge lamp tube is tempered (step 60) to eliminate the internal stress generated by the sealing operation of the entire glass tube 10, thereby increasing the strength of the glass tube 10.
由於冷陰極放電燈管需要有抽真空及填充汞的程序，因此玻璃管10之至少一端部11必須預留一抽氣管80。Since the cold cathode discharge lamp requires a process of evacuating and filling the mercury, at least one end portion 11 of the glass tube 10 must have an exhaust pipe 80 reserved.
如「第8圖」所示，在需要預留抽氣管80的場合下，則是以電極治具固定電極的同時(步驟10)，也固定抽氣管80。如此一來，在步驟21中，抽氣管80也會隨同電極22進入。當步驟40中以夾具60對玻璃管10封口時，則保持抽氣管80於可通氣的狀態。在最後透過抽氣管80完成抽真空及填充汞的程序之後，才以一般封口技術密封抽氣管。As shown in Fig. 8, when it is necessary to reserve the exhaust pipe 80, the electrode is fixed while the electrode fixture is fixed (step 10), and the exhaust pipe 80 is also fixed. As a result, in step 21, the exhaust pipe 80 also enters along with the electrode 22. When the glass tube 10 is sealed with the jig 60 in step 40, the evacuation tube 80 is maintained in a ventilated state. After the process of evacuating and filling the mercury is finally completed through the suction pipe 80, the suction pipe is sealed by a general sealing technique.
如「第9圖」所示，步驟30中說明了以二組火炬50於玻璃管10由玻璃管10二側對玻璃管10之端部11加熱，以完整地對整個玻璃管10的外周面加熱。在使用單一火炬50的場合下，可以機台持續帶動玻璃管10旋轉，使單一火炬50也能均勻且完整地對整個玻璃管10的外周面加熱。As shown in Fig. 9, it is explained in step 30 that the end portions 11 of the glass tube 10 are heated by the two sets of torches 50 on the glass tube 10 from both sides of the glass tube 10 to completely cover the outer peripheral surface of the entire glass tube 10. heating. In the case where a single torch 50 is used, the machine can continuously rotate the glass tube 10 so that the single torch 50 can uniformly and completely heat the outer peripheral surface of the entire glass tube 10.
本發明之無接痕大直徑冷陰極放電燈管之加工製作方法，取代了傳統多段融接的方式，不會在大尺寸燈管二端的形成接痕。且本發明所提出之方法，可以使用機械取代手工，對大直徑且大尺寸之玻璃管10進行封口。前述玻璃管之直徑尺寸介於6mm至20mm之間，常見之規格有6、7、8、9、10、12、15、16、18、19、20mm。而透過治具固定玻璃管，並以機械取代手工，因此，玻璃管之長度也可以加長(手工融接時，過長的玻璃管會造成施工之困難)，其長度可為1公尺至3.6公尺間，常見之規格有1.2、1.5、1.6、1.8、2.0、2.2、2.4、2.8、3.0、3.2、3.6公尺。因此，透過本發明製作方法製作之冷陰極放電燈管，可以廣泛地用於製作大型燈具，使冷陰極放電燈管更適合應用於照明或是大尺寸顯示單元之背光需求中。The processing method for manufacturing the jointless large-diameter cold cathode discharge lamp of the invention replaces the traditional multi-stage fusion method, and does not form a joint at the two ends of the large-sized lamp tube. Moreover, the method of the present invention can be used to seal the large diameter and large size glass tube 10 by mechanical substitution. The aforementioned glass tube has a diameter ranging from 6 mm to 20 mm, and the common specifications are 6, 7, 8, 9, 10, 12, 15, 16, 18, 19, 20 mm. The glass tube is fixed by the fixture and replaced by mechanical means. Therefore, the length of the glass tube can be lengthened (the length of the glass tube may cause construction difficulties when manually spliced), and the length can be from 1 meter to 3.6. Common specifications are 1.2, 1.5, 1.6, 1.8, 2.0, 2.2, 2.4, 2.8, 3.0, 3.2, 3.6 meters. Therefore, the cold cathode discharge lamp tube produced by the manufacturing method of the invention can be widely used for making large-scale lamps, and the cold cathode discharge lamp tube is more suitable for use in illumination or backlight requirements of large-sized display units.
