Technical Field

[1] The present invention relates to a manufacturing method of Cold Cathode

Florescent Lamp (CCFL) and apparatus thereof, more specifically, to a manufacturing method of CCFL and apparatus thereof in which uniformly coats a fluorescent substance irrespective of the length of a bulb, protects any deformation of the bulb at a process of oxidizing an organic binder, and much reduces the vibration of the bulb occurred at transferring between respective processes, reduces the rotating time of bulb delivered to an electrode sealing equipment in order to install electrodes at both ends of the bulb, improves cleaning ability of the bulb formed with both protecting layer and fluorescent layer, and shortens cleaning time, so as to improve productivity of CCFL and workability. Background Art

[2] Generally, in order to manufacture CCFL, a bulb is coated with a protection layer and a fluorescent substance on its inside surface, is baked with a high temperature, is installed with electrodes at both ends of the bulb, is sealed through a vacuum exhausting process, and is charged with mixture gas such as a certain of mercury, Argon and Neon, etc. in its inner space. In the meantime, when a higher voltage applies to the electrodes installed at both ends of the bulb, ultraviolet rays may be emitted with mercury being excited due to electron emission by electric field from the electrodes. The ultraviolet rays may convert itself to visible rays by the florescent substance and light is irradiated. Therefore, it is called CCFL because of a method of electron emission through the electric field instead of heating.

[3] More specifically, the general manufacturing method of the CCFL is divided into a coating process, an electrode- sealing process, an exhausting process, a mercury diffusion process and an inspection process. In the coating process, it may comprise a cleaning stage repeatedly both cleaning and drying bulb being cut in a certain of size, a coating stage coating a protection layer and florescent layer in inside surface of the bulb, a neck cleaning stage removing the coated florescent substance by reciprocally rotating both the bulb and a brush in order to seal an electrode at a bottom of the bulb, and a baking stage attaching the florescent substance into an inner wall of the bulb with an adhesive substance while removing any organic binder included in both the protection layer and the florescent layer by heating the bulb passed through the neck cleaning stage. [4] The electrode- sealing process may comprise an A-electrode preliminary sealing stage pinching an electrode in order not to come out the electrode after inserting the electrode at an end of the bulb, a B-electrode sealing stage closing the other end of the bulb after inserting an electrode at the other end of the bulb, and a getter room forming stage forming a space to be inserted a getter at an end of the bulb being installed with the A-electrode.

[5] The exhausting process may comprise an exhausting stage making an inner space being vacuum after inserting the getter in the getter room formed at an end of the A- electrode, a heating & exhausting stage making the inner space being high vacuum while removing impurity gas by consecutively performing a cleaning stage inserting cleaning gas such as Argon into the inner space being vacuum, and a sealing stage enveloping the getter room after inserting a certain of mixture gas of such an inert gas as Argon or Neon as a discharging gas into the inner space of a lamp passed through the heating & exhausting stage.

[6] The mercury diffusion process may comprise a mercury first diffusion stage either extracting or diffusing the mercury included in the getter being inserted in a lamp by applying a high frequency wave, a sealing & cutting stage cutting an end including the getter room while being completely sealed the A-electrode being preliminarily sealed that is formed in the getter room, a mercury second diffusion stage uniformly diffusing the mercury gas over the bulb by overall heating the bulb in sealing state with being installed with the A-electrode and B-electrode at both ends of the bulb.

[7] The inspection process may comprise a lead-acid treating stage revivifying electrode leads of the A-electrode and B-electrode stained black at sealing & cutting both ends of the bulb, a dipping stage coating mercury on the electrode leads, an aging stage stabilizing lighting status by applying voltage to both A-electrode and B- electrode sealed in both ends of the bulb, and a cutting stage cutting the electrode leads of a lamp passed through the aging stage, in accordance with standardization.

[8] In the manufacturing method of the CCFL passing through a plurality of processes as above, it may have some restraints since the bulb is 2 through 4 mm in diameter, but much longer in length. More specifically, first, there is a problem in which the uniformity of brightness and radiation characteristics by color are deteriorated at lightning due to irregularity of the thickness of both top and bottom of the florescent layer being coated in the inside of the bulb, resulting from being coated the bulb in perpendicular at the coating stage of the coating process.

[9] Secondly, the bulb is also bent or warped at the process attaching luminescent substance into the inner wall of the bulb after removing any organic binder included in the luminescent layer by heating the bulb being in perpendicular at the baking stage of the coating process, so that it may cause much inferiority. [10] Third, the bulb may have vibration at conveying it between the respective processes because the bulb is conveyed in perpendicularity, and also the conveying time is longer because it has to be conveyed one by one, so that the productivity may be much decreased.

[11] As shown in Fig. 1, the traditional manufacturing apparatus of CCFL mainly includes a coating equipment 1 coating a protection layer and florescent substance; a neck cleaning equipment 2 cleaning an end of the bulb coated with the protection layer and fluorescent substance; a baking equipment 3 removing organic material; an electrode sealing equipment 4 forming a getter room for inserting a getter while forming A & B electrodes at both ends of the bulb; a heating & exhausting equipment 5 enveloping the getter after both removing impurity gas and injecting discharge gas, while repeatedly performing gas cleaning process with the bulb formed with the A & B electrodes at the heating & exhausting process; a sealing & cutting equipment 6 shaping a lamp after enveloping the electrodes preliminary sealed at one side of the bulb and cutting the getter room; a heating equipment 7 overall diffusing mercury extracted out of the getter by a high frequency equipment into the lamp; and an aging equipment 8 stabilizing the status of lighting by applying voltage from an aging inverter to the A & B electrodes installed at both ends of the lamp.

[12] Transporting conveyers are installed at the respective equipments and the bulb, a raw material, is changed to CCFL (lamp) after passing through the equipments. More specifically, a transporting conveyer (a) is installed among the respective equipments, the coating equipment 1, the baking equipment 3, the electrode sealing equipment 4, the heating & exhausting equipment 5, the sealing & cutting equipment 6, the heating equipment 7 and the aging equipment 8, and a conveying equipment 10 is also installed for delivering the bulb to/from the respective equipments at both ends of the transporting conveyer (a).

[13] Since the conveying equipment 10 installed to the respective equipments have same configuration, as below is illustrated for the conveying equipment 10 delivering the bulb to the coating equipment 1 from the transporting conveyer (a).

[14] As illustrated in the Figs 2 through 4, the conveying equipment 10 comprises a vertical stopper 21, a horizontal stopper 22, a pair of upholding brackets 20 installed on a table of the coating equipment 1. The conveying equipment 10 further comprises a rotating axis 23 and an upholding axis 24 which are installed on the upholding brackets 20 on the same flat. It further comprises an outer gear 25 which is being united with the rotating axis 23 and a keypin, a half moon typed inner gear 27 installed at one side of the upholding bracket 20 by a hinge axis 26, while being occluded with the outer gear 25, a moving housing 28 being united with the rotating axis 23 by bolt, and a housing case 29 covering the moving housing 28. In the housing case 29, there are a moving bar 30, an inner bevel gear 31, and an outer bevel gear 22 being occluded with the inner bevel gear 31 while being united with a lower part of the moving bar 30.

[15] An arm 33 is attached at one side of the inner gear 27 and united by bolt. A vertical moving load 34 is installed in the arm 33 and united by a hinge combination. The vertical moving load 34 is either ascended or descended vertically by a cam of a drive train driving the coating equipment 1, which is not shown in the drawings.

[16] Moreover, a pair of intervening parts 12 for either taking or releasing bulb 11 is installed on the top of the moving bar 30. The intervening parts 12 are operated by pneumatic pressure. Their specific configuration is common technology.

[17] With respect to the operation of the conveying equipment 10, when the vertical moving load 34 is ascended by a cam being installed in a drive train of the coating equipment 1, the half moon typed inner gear 27 rotates counterclockwise but the outer gear 25 rotates clockwise so that the rotating axis 23 is rotated.

[18] Since the moving housing 28 is being united with the rotating axis 23, the moving housing 28 also rotates, when the rotating axis 23 rotates. In the meantime, the housing case 29 also rotates due to being united with a side of the moving housing 28. Therefore, the inner bevel gear 31 rotates and the outer bevel gear 32 also rotates which is being united with the inner bevel gear 31. Since the outer bevel gear 32 is installed in the lower part of the moving bar 30, the moving bar 30 is rotated while being moving in horizontal position.

[19] Namely, in order to deliver a bulb 11 moving through a transporting conveyer (a) perpendicularly to the coating equipment 1, the conveying equipment 10 takes the bulb 11 horizontally and delivers the bulb 11 to the coating equipment 1 after rotating at an angle of 180 degrees while moving vertically. Referring to Fig. 2, the arm 33 is positioned at the top since the vertical moving load 34 is ascended by the cam installed at the drive train of the coating equipment 1, when the intervening part 12 installed at the moving bar 30 of the conveying equipment takes the bulb 11. In the meantime, the moving bar 30 is being supported by a horizontal stopper 22 installed by an upholding bracket 20.

[20] Under the condition as above, when a drive train of the coating equipment 1 rotates, the vertical moving load 34 is descended by a cam of the drive train. As the vertical moving load 34 is being descended, the arm 33 of the half moon typed inner gear 27 being hinge combination with the vertical moving load rotates clockwise and the outer gear 25 being occluded with the half moon typed inner gear 27 rotates counterclockwise so that the rotating axis 23 is rotated. In the meantime, the moving bar 30 taking the bulb 11 moves vertically and the outer bevel gear 32 installed in the lower part of the moving bar 30 is rotated by the inner bevel gear 31 operating with the outer gear 25. If the arm 33 of the half moon typed inner gear 27 moves to a midway between a top point and a bottom point, the moving bar 30 taking the bulb 11 is completed its rotating at an angle of 90 degrees. (Referring to Fig. 3)

[21] Under the condition as above, when the half moon typed inner gear 27 reaches the bottom point, the moving bar 30 is under perpendicularity by the outer gear 25 rotating. The moving bar 30 being in perpendicular is supported by the vertical stopper 21 installed at the upholding bracket 20. Moreover, the outer bevel gear 32 is rotated by the inner bevel gear 31 operating with the outer gear 25. In conclusion, the bulb 11 may be efficiently delivered to the coating equipment 1 from the transporting conveyer a, since the bulb 11 is rotated at an angle of 180 degrees from right to left in view of the moving bar 30 as well as moving from vertical status to horizontal status.

[22] The conventional conveying equipment 10 has several problems in delivering bulb

11 from the transporting conveyer (a) being in horizontality to coating equipment 1 being in perpendicularity because the bulb 11 is 2 through 4 mm in diameter, but much longer in length in comparison with the diameter. More specifically, there is a problem to deteriorate the reliability of workability due to abrasion of the component parts resulting from long and repetitive use while the component parts are coupled in both machine and mechanism respectively in both rotating and moving the moving bar 30.

[23] Second, the moving bar moving bar 30 delivering bulb 11 is taken impact by the horizontal stopper 22 and the vertical stopper 21 which are installed at the upholding bracket upholding bracket 20. Therefore, there is a problem in that the bulb 11 may have constraints in its length.

[24] Third, there is a problem in efficiently utilizing the space for acquiring the working space sufficiently to both rotate and move the moving bar 30 taking the bulb 11.

[25] Fourth, there is a problem in keeping productivity due to less speedy operating time resulting from delivering bulb 11 while a moving bar 30 moves forward and backward at right angle.

[26] Fig. 5 is an exemplary drawing for electrode sealing equipment installed the conventional rotating equipment.

[27] Figs. 6 through 7 is brief front and side views for the conventional rotating equipment.

[28] Referring to Figs. 1, 5 through 7, the bulb rotating equipment is installed at electrode sealing equipment 4 forming a getter room for inserting a getter, while forming A & B electrodes at both ends of the bulb. Referring to Fig. 5, an A electrode forming rotating equipment 9b and a B electrode forming rotating equipment 10b are installed on the table at regular intervals, and a rotating equipment 15b rotating bulb at an angle of 180 degrees is installed between the A electrode forming rotating equipment 9b and the B electrode forming rotating equipment. An A electrode beading device 13b and a B electrode beading device 14b furnishing with a transporting rail 12b are installed in the A electrode forming rotating equipment 9b and the B electrode forming rotating equipment 10b, so that A & B electrodes are provided. The rotating equipment 15b may comprise a moving & rotating device 1 Ib which moves bulb from the A electrode forming rotating equipment 9b to the B electrode forming rotating equipment 10b.

[29] With respect to a conveying equipment supplying bulb from a transporting conveyer in the A electrode forming rotating equipment A electrode forming rotating equipment 9b, a conveying equipment pushing bulb formed with electrodes to a transporting conveyer (or a hopper for collecting) in the B electrode forming rotating equipment 10b, the A electrode forming rotating equipment 9b, the B electrode forming rotating equipment 10b, and an intervening plate holding bulb on the moving & rotating device, their operations are common knowledge, so the explanation on their operation is omitted.

[30] Referring to Fig. 6 and 7, the rotating equipment 15b installed on the electrode sealing equipment 4 may comprise a bevel gear box 16b that is installed on the table and furnished with an input axis on horizontality and an output axis on perpendicularity, an oscillator box 17b which is furnished with an input axis on perpendicularity and an output axis on horizontality, a rotating arm 20b which is installed at the output axis on horizontality and furnished with a rotating control spring 18b and a bulb intervening plate 19b. In the meantime, power is supplied by gears being occluded between an output axis of the bevel gear box 16b and an input axis of the oscillator box, and between an output axis of the oscillator box 17b and the rotating arm.

[31] With respect to the operation of the rotating equipment 15b, when power is supplied to the input axis of the bevel gear box 16b through chains from a main driving train (Not shown), the power is delivered to the input axis of the oscillator box 17b while rotating the output axis installed in the bevel gear box 16b on its perpendicularity, and also delivered to the input axis of the oscillator box. Thereafter, the output axis of the oscillator box 17b is rotated in both forward and reverse positions within a certain of degrees and the rotating arm 20b being occluded with the output axis of the oscillator box 17b and gears may also be rotated in both forward and reverse positions at an angle of 180 degrees.

[32] Namely, the bulb is delivered to the moving & rotating device 1 Ib after forming both A electrode and a getter room at the A electrode forming rotating equipment 9b and the bulb is moved to the position of the rotating arm 20b in the rotating equipment. Then, the bulb intervening plate 19b of the rotating arm 20b intervenes the bulb. In the meantime, when power is supplied to the rotating arm 20b from the main driving train through both the bevel gear box 16b and the oscillator box 17b, the bulb is rotated at an angle of 180 degrees and released. In conclusion, the bulb is moved to a B electrode forming rotating equipment 10b under the state in which A electrode positioned at the bottom of the bulb is moved up to the top, in order to form B electrode at the bottom of the bulb.

[33] Since the moving & rotating device 1 Ib being installed between the A electrode forming rotating equipment 9b and the B electrode forming rotating equipment 10b, as a component of the rotating equipment 15b is installed as a single, the operation of which the rotating equipment 15b intervenes bulb, rotates at an angle of 180 degrees, and release the bulb again has to be repeated, resulting in increasing the workable time and causing lower productivity.

[34] Fig. 8 is an exemplary drawing showing an overall and partially magnified configuration of the conventional neck cleaning equipment.

[35] Fig. 9 is a magnified exemplary drawing of a brush rotating part of the conventional neck cleaning equipment.

[36] Referring to Figs 1, 8 through 9, a neck cleaning equipment 2 cleaning a side of a bulb 14c has an index unit 10c installed at a rectangular typed frame 9c and a transporting conveyer l ie installed on the frame 9c. The transporting conveyer l ie comprises chains having jigs to be put bulb 14c, and sprocket at its both ends. The jigs are on top of the frame 9c, and are attached at regular intervals on the chains. The transporting conveyer 1 Ic is moved at regular speed by the index unit 10c.

[37] A drying part 12c is installed on the top of the transporting conveyer 1 Ic in order to dry the cleaning part of the bulb 14c on which is both coated and dried through the coating equipment coating equipment 1, with hot air. An elevator is installed at both sides of the transporting conveyer 1 Ic in its width position to be put the bulb. A folded frame (Not shown) being a combination with the frame 9c is installed on the flat line with the elevator. A brush rotating part 30c is installed for cleaning the inside of the bulb by inserting a brush into a bulb rotating part 20c rotating the bulb 14c delivered from the elevator and the bulb 14c.

[38] The bulb rotating part 20c may comprise a bulb driving motor 21c, an inner roller

22c and an intervening roller 23c that is either expanded or contracted by air. In case that the bulb 14c is positioned between the inner roller 22c and the intervening roller 23c by the elevator, the bulb driving motor 21c operates and the bulb 14c rotates reversely to the direction that the brush rotates.

[39] A moving plate 32c is installed on an supporting plate 31c being fixed on a frame

9c, and a pair of brush chuck 33c and a inner motor 34c are installed on the moving plate 32c, so that driving power is delivered by a timing belt. The moving plate 32c may comprise a telescopic cylinder 35c moving either forward or backward along rails. In the meantime, a permanent magnet is installed in the brush chuck 33c so that a brush holder 37c installed a resin typed brush 36c may unify itself by being inserted into the brush chuck 33c. Moreover, a gazing jig 38c is installed in the moving plate 32c in order to set the position of the bulb 14c so that it may clean the bulb uniformly. An inlet valve 39c connected to a dust collector 15c is installed at the bottom of the brush chuck 33c in order to inlet dust of fluorescent substance occurred at the cleaning processing. Therefore, the cleaning efficiency may be much improved by removing the dust and power attached in the fluorescent substance.

[40] The elevator and the drying part 12c are not specifically illustrated in the drawings.

The elevator is installed at both ends of the bulb 14c moving on the jig of the transporting conveyer l ie. The elevator, bulb rotating part 20c and brush rotating part 30c are all installed on the same plane and they are also positioned on the same flat in both side and front views as the elevator ascends. The drying part 12c, not shown in drawings, dries the bulb 14c with hot air through a heater unit in order to protect any detachment of fluorescent substance and cleaning inferiority at cleaning the coated layer coated in the bulb 14c. The heater unit is installed in a block in which is ascended by a cylinder and supplies hot air through nozzle.

[41] In case that a bulb 14c coated with fluorescent substance through the coating equipment 1 moves to same position as a groove of the block by using the conventional neck cleaning equipment 2, the heater unit is ascended by the operation of cylinder. Then, one end of the bulb 14c is dried by hot air through nozzles and the bulb 14c moves to the position of the elevator while being put on the jig.

[42] After moving to the position of the elevator, the bulb 14c is ascended to a same flat plane (either side view or front view) of both bulb rotating part 20c and brush rotating part 30c by the operation of the elevator. Then, the bulb 14c is rotated and the resin typed brush 36c cleans the dried fluorescent substance by being inserted into an end of the bulb 14c since the resin typed brush 36c rotates reversely to the rotating position of the bulb 14c.

[43] The bulb 14c is moved to an electrode sealing equipment 4 for sealing electrode through a baking equipment 3 for removing organic material after florescent substance on the bulb 14c is cleaned.

[44] The conventional neck cleaning equipment 2, however, simply cleans the florescent substance coated on both inside and outside surface of an end of the bulb 14c by rotatory power of an inner motor 34c after resin typed brush 36c is inserted into the bulb 14c moving. Therefore, the resin typed brush 36c is easily abrasive, has lower cleaning ability and its reliability on rotation is much decreased because the bulb 14c is rotated by friction due to close adhesion of both the inner roller 22c and the intervening roller 23c.

[90] The present invention is described more fully hereinafter. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[91] It will be understood that when an member or layer is referred to as being "on",

"connected to" or "coupled to" another member or layer, it can be directly on, connected or coupled to the other member or layer or intervening members or layers may be present. In contrast, when a member is referred to as being "directly on," "directly connected to" or "directly coupled to" another member or layer, there are no intervening members or layers present. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

[92] It will be understood that, although the terms first, second, third etc. may be used herein to describe various members, components, regions, layers and/or sections, these members, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one member, component, region, layer or section from another region, layer or section. Thus, a first member, component, region, layer or section discussed below could be termed a second member, component, region, layer or section without departing from the teachings of the present invention.

[93] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, members, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, members, components, and/or groups thereof.

[94] Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[95] The manufacturing method of a cold cathode fluorescent lamp according to the first embodiment of the present invention comprises a coating process having a cleaning stage, a coating stage, a neck cleaning stage and a baking stage, an electrode sealing process having an A-electrode preliminary sealing stage, a B-electrode sealing stage and a getter room forming stage, an exhausting process having an exhausting stage, a charging stage of discharge gas and an enveloping stage, a mercury diffusion process having a first mercury diffusion stage, a sealing & cutting stage and a second mercury diffusion stage, and, an inspection process having a lead-acid treating stage, a dipping stage, an aging stage and a cutting stage.

[96] The luminescent substance may be uniform in thickness in the inner wall of the bulb, since the luminescent substance coated in liquefied form along the inner wall of the bulb flows along the inner wall of the bulb, as long as the bulb inserted in perpendicularity rotates with a slope of a certain degrees at the coating stage of the coating process.

[97] Namely, after the luminescent substance is coated in liquefied form into the inner wall of the bulb, the bulb is rotated at a certain slope. Then the luminescent substance coated rotates and flows along the inner wall of the bulb, consequently, the thickness of the fluorescent substance coated into the inner wall of the bulb may be uniform.

[98] The slope of the bulb is preferable to be about 4 through 10 degrees based on a perpendicular line, and it may be adjusted according to viscosity of the luminescent substance to be coated and the length of the diameter of the bulb.

[99] In case that a metal brush washing inner wall of the bulb rotates in a close manner to the inner wall of the bulb under a circumstances being generated a magnetic force at an end of the bulb at the neck cleaning stage, the coated luminescent substance may be more efficiently removed than the conventional method of rotating the bulb and a resin typed general brush reciprocally each other.

[100] Especially, the coated luminescent substance may be efficiently removed with the metal brush because of removing the luminescent substance with the magnetic force in a close manner to the inner wall of the bulb, even though the metal brush wears down. Moreover, the processing time to remove the luminescent substance may be reduced due to being rotated the metal brush in a close manner to the bulb.

[101] It may be more preferable to exert the magnetic force being acted from the outer wall of the bulb at one position. It may also be preferable for magnetic source acting from the outer wall of the bulb to be a magnetic substance having a higher gauss. In the meantime, it may be preferable for the metal brush being inserted to the inside of the bulb and being closer to the inner wall of the bulb to be moveable by magnetic force.

[102] By rotating a quartz tube in a horizontal condition being made of quartz material and being strong in high temperature in which a plurality of bulbs are inserted at the baking stage of the coating process, the bulb may prevent from being bent or deformable at the baking stage that attaches the luminescent substance to the inner wall of the bulb.

[103] In the meantime, since it may have a plurality of bulbs passed the coating stage in a quartz tube in horizontal condition that is made of quartz and strong to heating, any deformation of the bulbs may be protected. It is because a plurality of bulbs may be indirectly heated through the quartz tube rather than direct heating if the quartz tube is rotated and heated. If hot air having moderate heat is applied at a side, the characteristics and lifetime of a lamp may also improve since the hot air having moderate heat efficiently removes organic binder and protects re-adhesion of impurity gas at the baking stage.

[104] Moreover, superheat may locally apply to the bulb at the getter room forming stage of the electrode sealing process, the charging stage of discharge gas and enveloping stage of the exhausting process. Even though it partially has a bending phenomenon at this process, it may straighten the bent Bulb by rotating the quartz tube incorporating a plurality of bulbs in a horizontal position.

[105] It may improve the efficiency of the process that the bulbs insert in a folded manner to the inside surface of the quartz tube, rather than the state in which they are stacked. Moreover, it may provide CCFL having superior characteristics and various typed products because bulbs having a length of more than 500 mm are performed through this method using the quartz tube.

[106] More specifically, in case that the bulbs are inserted into the quartz tube within a range of 15 degrees in both right and left position from a perpendicular line, it may straighten the deformed bulb by rotating the bulb along the inside surface of the quartz tube in horizontal position.

[107] Moreover, the bulb is conveyed at 90 degrees at conveying to the other process.

However, it may be possible to convey the bulb by dividing the moving degrees, for example, conveying it at 45 degrees, rotating it at 180 degrees and conveying it 45 degrees again. Therefore, it may minimize the vibration of the bulb occurred at conveying process between the respective processes and also shorten the transporting time.

[108] More specifically, it is supposed that a bulb is conveyed in perpendicularity to next stage, while the other bulb is conveyed in horizontality. Therefore, in order to simultaneously hold the bulbs in both perpendicularity and horizontality, the bulbs may be conveyed at 45 degrees, rotated at 180 degrees and again conveyed at 45 degrees, consequently, a bulb may be kept in horizontality for conveying to next stage after completing a process, and the other bulb in perpendicularity after conveying for another process.

[109] Namely, the bulbs may convey in both perpendicularity and horizontality for the respective process, therefore, in comparison with the traditional conveying process, the conveying time may be reduced by half so that the workability and productivity may be much improved.

[110] As above, the manufacturing method of CCFL according to the first embodiment of the present invention makes the bulb inserted in perpendicularity rotate with a slope of a certain degrees at the coating stage of the coating process, makes a metal brush rotate in closely adhering to the inner wall of the bulb under a circumstances being generated a magnetic force at an end of the bulb at the neck cleaning stage, performs the baking stage and the second mercury diffusion stage in horizontality by inserting a plurality of bulbs in a quartz tube made of quartz strong to heating, and makes the bulbs convey at 45 degrees, rotate at 180 degrees and again convey at 45 degrees, instead of rotating the bulbs at 90 degrees. Therefore, the present invention may uniformly coat a fluorescent substance irrespective of the length of a bulb, shorten the cleaning time for a side of the bulb, protect any deformation of the bulb at a process of oxidizing an organic binder, minimize the vibration of the bulb occurred at conveying process between the respective processes and shorten the transporting time so that it may improve productivity and workability.

[123] A motor rotating in both directions 405 is installed at the driving pulley 403, top/ bottom moving sensing sensors 406 and 407 are installed on both top and bottom of the inclined bottom plane of the guide frame 400, a pair of inside/outside moving guides 412 and 422 are installed at inner surface of the inside/outside moving brackets 411 and 421, a position sensing sensor 413 is installed at lower part of the inside moving bracket 411, and an intervening plate 423 is attached on top part of the outside moving bracket 421 so as to make a single body with a timing belt 404.

[124] A rotating part 500 may be installed between the upholding frame 300 and the guide frame 400. And, a rotating guide may be installed in the S typed winding rail being installed at inner side of the upholding frame 300 and make a single body with the rotating part 500.

[125] The rotating part 500 may comprise a rotating arm 510 rotating a moving bar 30 having an intervening part taking a bulb 11, a guide arm 520 making a hinge combination with the rotating guide 600, and a pipe typed connecting axis 530 being made a single body with the rotating arm 510 and the guide arm 520.

[126] The rotating guide 600 may comprise a guide body 610 having a groove 611, a variable body 620 being installed an oilless bearing 621 at its both sides and formed an inserting groove 622, a pair of guide axes 630 installed at the guide body 610 in length, united with the oilless bearing 621 of the variable body 620 and inserted with a coil spring 631, a pair of guide rollers 623 and 613 installed on top part of the variable body 620 and the guide body 610, and a connector 640 being made a single body with the guide body 610 and making a hinge combination with the guide arm 520.

[127] The number 40 in the drawings is a through hole formed at the inside/outside moving brackets 411 and 421 in order to insert the pipe typed connecting axis 530. The number 42 is a tension pulley in which is installed among the rotating pulley 401, an upholding pulley 402 and the driving pulley 403, and generates tensible force to the timing belt 404. The numbers 44 and 46 are a plurality of connecting pole which have the upholding frame 300 and the guide frame 400 make a regular interval and a single body, and a connecting bracket. The number 48 is a gap mediation bolt adjusting the gap of the variable body 620 installed at the groove 611 of the guide body 610.

[128] A slide conveying equipment according to the first embodiment of the present invention is an apparatus installed at the transporting conveyer in order to perform next process after delivering bulb to/from respective equipment. Therefore, the apparatus may be used as an apparatus of CCFL and general fluorescent lamp including External Electrode Fluorescent lamp (EEFL). A pair of conveying equipments having the same configuration in the respective equipment is installed. It will be illustrated about the operation of the conveying equipment 10 delivering bulb to the coating equipment 1 from the transporting conveyer (a).

[129] Referring to FIGS. 10 through 15, an supporting plate 200 of a body of transporting equipment 100 is firmly installed at one side of a transporting conveyer (a), and made a single body with the transporting conveyer (a). In the meantime, an upholding frame 300 installed on the supporting plate 200 along a slant line is made a single body with a guide frame 400 by welding.

[130] An S typed winding rail 310 is installed in inner surface of the upholding frame

300. Moreover, the guide frame 400 has inside/ outside moving rails 410 and 420 and inside/outside moving brackets 411 and 421 installed at the same position as its inner and outer sides. A pair of inside/outside moving guides 412 and 422 installed at inside/ outside moving brackets 411 and 421 is combined with the inside/outside moving rails 410 and 420 so that the inside/outside guide 412 and 422 may slide. Therefore, the inside/outside moving brackets 411 and 421 may slide in the event.

[131] The inside/outside moving brackets 411 and 421 may be moved by driving force of a motor 405 rotating in both directions installed on top of the guide frame 400. More specifically, a rotating pulley 401 is installed on top of the guide frame 400, and a driving pulley having the motor 405 rotating in both directions is installed at bottom of the guide frame 400. Moreover, an upholding pulley 402 is installed between the rotating pulley 401 and the driving pulley 403. In the meantime, a tension pulley 42 is installed at both sides of the upholding pulley 402 so that a timing belt 404 being made a single body with the respective pulley may generate tensible force.

[132] Since the timing belt 404 is made a single body with an intervening plate 423 being installed on top of the outside moving bracket 421, the timing belt 404 may rotate if electric signal delivers to the motor 405 rotating in both directions, and the outside moving bracket 421 may also move along the outside moving rail 420.

[133] Since the outside moving bracket 421 makes a single body with the inside moving bracket 411 by a connection axis of a rotating part 500, the inside moving bracket 411 may simultaneously move as the outside moving bracket 421 moves.

[134] The connecting axis 530 is made a single body with the inside/outside moving brackets 411 and 421 through a through hole 40. Therefore, since the connecting axis 530 moves, a rotating guide 600 being made a hinge combination with a guide arm 520 installed at one end of the connecting axis 530 may rotate along the S typed winding rail 310 clockwise.

[135] Referring to the FIGS. 12 through 16, when the outside moving bracket 421 reaches bottom of the guide frame 400, the top moving sensing sensor 406 installed at the inclined bottom plane of the guide frame 400 may sense a position indicating in a position moving sensor 413. Then, the motor 405 rotating in both directions may receive an electric signal to rotate itself forward, and the inside/outside moving brackets 411 and 421 may be ascended along the inside/outside moving rails 410 and 420.

[136] Therefore, the connecting axis 530 of the rotating part 500 may move as the inside/ outside moving brackets 411 and 421 move, and the guide arm 520 being installed at one end of the connecting axis 530 may be rotated by the rotating guide 600 moving along the S typed winding rail 310. In the meantime, the rotating position of the guide arm 520 may be determined by the position of whether the inside/outside moving brackets 411 and 421 are moved.

[137] Namely, if the inside/outside moving brackets 411 and 421 move from top of the guide frame 400 to bottom of the guide frame 400, the guide arm 520 may be rotated counterclockwise. On the contrary, if the inside/outside moving brackets 411 and 421 move from bottom of the guide frame 400 to top of the guide frame 400, the guide arm 520 may be rotated clockwise.

[138] Referring to FIGS. 15 through 17, the rotating guide 600 may comprise a guide body 610 having a groove 611, a variable body 620 which has oilless bearings 621 at its both sides and an inserting groove 622, a pair of guide axes 630 which is installed at the guide body 610 in its length, united with the oilless bearings 621 in the variable body 620 and wrapped with a coil spring 631, and a pair of guide rollers 623 and 613 installed on top part of the variable body 620 and the guide body 610, and a connecting pole 640.

[139] In order for the rotating guide 600 to properly move along the S typed winding rail

310, a pair of guide rollers 613 and 623 may be installed on top of both the guide body 610 and the variable body 620. The variable body 620 may have a pair of the guide axis 630 being wrapped a coil spring 631 at its both sides so that the coil spring 631 supports one side of the variable body 620. Another coil spring 624 may be inserted in the inserting groove 622 formed at center portion of the other side of the variable body 620. Therefore, the variable body 620 may move along the guide axis 630 within the groove 611 of the guide body 610, and the guide rollers 613 and 623 installed at the guide body 610 and the variable body, respectively may move properly along the S typed winding rail 310.

[140] As to the slide conveying equipment of a manufacturing apparatus of CCFL according to exemplary embodiment of the present invention, a S typed winding rail 310 is installed in inner surface of the upholding frame 300, and the guide frame 400 has inside/ outside moving rails 410 and 420 and inside/outside moving brackets 411 and 421 installed at the same position as its inner and outer sides. And, an intervening plate 423 is attached on top of the outside moving bracket 421 so that it may make a single body with the timing belt 404 being rotated by the motor 405 rotating in both directions. Moreover, the rotating part 500 may be installed between the upholding frame 300 and the guide frame 400, and the rotating guide 600 may be installed in the S typed winding rail 310 being installed at inner side of the upholding frame 300. The rotating guide is being made a single body with the rotating part 500. In the meantime, the inside/outside moving brackets 411 and 421 having the connecting axis 530 of the rotating part 500 is doing straight-line motion and the guide arm 520 installed at one end of the connecting axis 530 may rotate and move along the S typed winding rail 310. Therefore, since the rotating arm moves and rotates simultaneously, the moving bar 30 holding the bulb 11 may also smoothly move. In conclusion, any vibration of the bulb may be minimized and longer bulb may be properly conveyed so that it may diversify standardized goods of CCFL. Meanwhile, since the rotating part 500 is doing straight- line motion along the inside/outside moving rail 410 and 420, and S typed winding rail 310, and is rotated by the guide arm 520, it may protect being loose due to abrasion in machine and mechanism according to the tradition, so that higher reliability of workability may be achieved.

A housing 60a having a stepped connecting bracket 62a making a hinge connection with lower part of a pair of arms may be installed on top part of a table 15a. The housing 60a may have a moving bar 64a having a rack bracket 63a at its inside and lower part. The housing 60a may have an expansion member 70a either being folded and expanded according to either expansion or contradiction of the moving bar 64a on its top part. And, a rotating member 80a may be installed between the lower part of the housing 60a and the table 9a.

[148] The expansion member 70a may comprise top/bottom loads 72a and 73a being made a single body by a connector 71a of a pair of arms 61a, and a driving load 74a making hinge connections with the connector 71a at its one end and with top part of the moving bar 64a at its other end.

[149] The rotating member 80a may comprise a pinion gear 81a being a single body with lower part of the housing 60a, a rack gear 82a occluding with the pinion gear 81a on the top part of the table 9a, and an telescopic cylinder 83a operating the rack gear 82a by electric signal of an operating sensing sensor 42a.

[150] A double arm conveying equipment according to the present invention may be used not only in the heating & exhausting equipment 5, but a coating equipment 1, a baking equipment 3, an electrode sealing equipment 4, and a sealing & cutting equipment as a conveying equipment delivering bulb. In order to efficiently understand the present invention, it will be illustrated about an example of the heating & exhausting equipment. Moreover, this equipment may be used as a manufacturing equipment of CCFL and general fluorescent lamp including External Electrode Fluorescent lamp (EEFL).

[151] Referring to the FIGS. 19 through 24, a housing 60a having a moving bar 64a may be firmly installed on top part of a table 9a, and a stepped connecting bracket 62a may be installed on top of the housing 60a. Moreover, lower part of a pair of arms 61a may be made a hinge connection at both ends of the stepped connecting bracket 62a.

[152] The top load 72a and the bottom load 73a may be made a single body by a co nnection pole 71a, and a driving load 74a located between the connection pole 71a and the moving bar 64a may be also made a hinge connection. Therefore, as the moving bar 64a either ascends or descends the arm 61a being a couple by the expansion member 70a may be folded or expanded.

[153] The moving bar 64a may be installed at the housing 60a in length, and either ascended or descended by an inner link 21a being operated by a cam 14a of a driving axis 13a. More specifically, a top upholding bracket 20a may be installed on bottom surface of the table 9a, and the top part of the inner link 21a may be made a hinge combination by a driving hinge axis 18a.

The rollers 33a may be made a combination with a rack bracket 63a of the moving bar 64a in being hung on the rack bracket 63a. Therefore, as the outer link 31a is working, the moving bar 64a of the housing 60a may ascend. Moreover, as the moving bar 64a ascends, a pair of arms 61a may be expanded or folded by the expansion member 70a in which is installed between top part of the moving bar 64a and the stepped connecting bracket 62a.

[155] At this point, since the roller 33a of the "D" typed bracket 32a in the outer link 31a is hung on the rack bracket 63a installed at bottom part of the moving bar 64a, the moving bar 64a may be moved. Therefore, the driving load 74a being made a hinge combination with top part of the moving bar 64a may push the connecting pole 71a being made a single body with the top/bottom loads 72a and 73a. In conclusion, a pair of arms 61a may be expanded and met a right angle in which makes a hinge combination with the top load 72a and the stepped connecting bracket 62a at its bottom part.

[156] Then, the inner axis 13a may rotate and the cam 14a may push the driving roller 22a of the inner link 21a. Since top of the inner link 21a makes a hinge combination with the top upholding bracket 20a, the bottom part of the inner link 21a may move clockwise. And, the outer link 31a may be identically moved as the inner link 21a by a line load 50a being a pivot combination with bottom part of the inner link 21a so that the "D" typed bracket 32a may push the moving bar 64a. While the inner link 21a moves, an outer hinge axis 19a may be used as a rotating axis.

[157] If the moving bar 64a is got out of the housing 60a, in other words, the moving bar

64a moves to the top of the housing 60a, the arms 61a being expanded in perpendicularity may be folded in a direction of moving bar 64a. While the outer link 31a is pushing the moving bar 64a, it may also operate an operation sensing sensor 42a being installed at a vertical bracket 40a. Then, a telescopic cylinder 83a of a rotating member 80a may be operated by electric signal generated from the operation sensing sensor 42a and the rack gear 82a may do straight-line motion.

[158] Referring to FIG. 21, a pinion gear 81a is installed at bottom of the housing 60a including the expansion member 70a. In the meantime, since the pinion gear 81a is occluded with a rack gear 82a, the housing 60a may be rotated as the rack gear 82a do straight- line motion. A damper (Not shown) may be installed at side of the rack gear 82a for controlling a moving distance of the rack gear 82a so as to rotate the housing 60a at an angle of 180 degrees. In conclusion, the arm 61a taking the bulb 1 lis which is positioned at the transporting conveyer (a) may be rotated to the heating & exhausting equipment 5, and the arm 61a delivering the bulb 11 to the heating & exhausting equipment 5 may be rotated to the transporting conveyer (a).

[159] Meanwhile, a moving distance of the moving bar 64a may be adjusted by the length of the line load 50a being installed between bottom part of the inner link 21a and bottom part of the outer link 31a. More specifically, if the hexagonal bar 53a of the line load 50a rotates clockwise, pivot bolts 51a and 52a may be clamped by the hexagonal bar 53a so that its distance may be reduced and the moving distance of the moving bar 64a may be also shortened. On the contrary, if the hexagonal bar 53a rotates counterclockwise, pivot bolts 51a and 52a may be taken off from the hexagonal bar 53a so that its distance may be extended and the moving distance of the moving bar 64a may be also lengthened.

[160] The arms 61a being a hinge combination with top of the housing 60a may be adjusted to rotate at an angle of 45 degrees by controlling the moving distance of the moving bar 64a according to the length of the line load 50a, as above. Moreover, the arms 61a being expanded may be at right angle. In conclusion, the bulb 11 putting in horizontality on the transporting conveyer (a) may be conveyed in perpendicularity.

[161] As to the double arm conveying equipment according to the second exemplary embodiment of the present invention illustrating FIGS. 19 through 24, the moving bar 64a of the housing 60a may be operated as the inner link 21a and outer link 31a may be operated by the cam 14a of the drive train 13a. And, the expansion member 70a and a rotation member 80a being installed at a pair of arms 61a may be connected each other. Therefore, while the arms 61a rotates at an angle of 45 degrees, an intervening part 12b of one arm 61a may take the bulb 11 putting on the transporting conveyer (a). At the same time, the other arm 61a may deliver the bulb 11 to the heating & exhausting equipment 5. In conclusion, the transporting time may be reduced in half and the workability may be improved. Moreover, as the damper 41a being installed at the vertical bracket 40a absorbs vibration of the outer link, the vibration of the bulb 11 may be minimized so that the reliability of workability may be much improved. Especially, since longer bulb can be conveyed efficiently, a variety of CCFL products may be obtained.

In conclusion, the moving block 54c may move forward or backward along the guide rail 52 of the supporting block 51c.

[191] The fixing chuck 56c may be installed in the bulb rotating member 57c. Since the fixing chuck 56c may be made a single body with a bulb inner motor 55c and timing belt through the bulb rotating member 57c, the fixing chuck 56c may be separately rotated within the bulb rotating member 57c. In the meantime, the pneumatic pressure may be used for the operation of taking the bulb 14c to be inserted into the fixing chuck 56c.

[192] As illustrated in the conventional neck cleaning equipment with respect to inserting bulb 14c into the bulb rotating part 50c, the bulb 14c moving under being put on the jig of the transporting conveyer transporting conveyer l ie may be ascended by an elevator 70c being installed at bottom part of the transporting conveyer 1 Ic.
