Description

  The present invention relates to a soldering apparatus for a thin fluorescent lamp used for soldering a component code such as a wire harness to a lead wire of a thin and long fluorescent lamp used as a backlight of a liquid crystal television.

  In recent years, thin and long fluorescent lamps having a diameter of several mm (for example, 2 mm) have been used as backlights for liquid crystal televisions. The length is about 30 cm to 70 cm with the spread of large-sized televisions, and a longer one will appear in the future.

  An example of a thin fluorescent lamp currently manufactured and sold is, for example, Japanese Patent Application Laid-Open No. 09-320532 (small fluorescent tube and small fluorescent tube device). In this fluorescent lamp, lead wires protrude from both ends of a straight tube-type long and small-diameter fluorescent lamp. The same applies to the double sealed lamp for surface light source disclosed in JP-A-10-283999. In Japanese Unexamined Patent Publication No. 2000-075801 (backlight unit and electronic device), a conductor of a cord (cable) in which a lead wire is slightly bent and hooked into a hook shape to ensure the strength of soldering the cord to the lead wire. A joining method in which the parts are hooked and soldered is shown.

  An electric cord such as a wire harness is soldered to the lead wire of the thin fluorescent lamp. After soldering, it is sent to an assembly factory where it is combined with other parts and incorporated into the liquid crystal screen.

  Conventionally, there is no special device for soldering the wire harness to this type of thin fluorescent lamp. The thin fluorescent lamp is placed horizontally on the work table and the cord is soldered to the lead wire protruding from the end. .

  However, if the thin fluorescent lamp is placed horizontally on the workbench and soldered to the electrode terminal protruding from the end, first, if the electrode terminal is bent in a small L shape, it will rotate. The work had to be fixed because the direction had to be fixed. Also, for example, after soldering one end of a long straight tube type thin fluorescent lamp, the long thin fluorescent lamp may be rotated 180 ° on the work table in order to solder to the electrode terminal at the other end. Or, the work position had to be changed. Since the thin fluorescent lamp is thin and long, the work of turning the thin fluorescent lamp after soldering the cord to one of the electrode terminals is very complicated, and the glass tube may be damaged. It is expensive, requires careful handling, and the work efficiency is significantly reduced.

A method of soldering the thin fluorescent lamp to the left and right electrode terminals while being fixed horizontally is also conceivable, but it is not efficient because the operator moves left and right. When changing the work position, it is almost impossible to do so because it is necessary to move the work table back and forth rather than simply moving left and right due to the dominant hand. Furthermore, since the long thin fluorescent lamps are placed horizontally, the work area is increased and the area efficiency of the factory is significantly impaired.

In order to make the working height appropriate, it is preferable that the horizontal axis is freely adjustable in vertical height with respect to the support column.

  The turning base is provided with a pair of restricting fittings that restrict and engage and fix both side ends of the setting jig. In order to facilitate the engagement / disengagement of the setting jig, it is most suitable that the restricting metal fitting sandwiches both sides of the setting jig with an appropriate spring material or the like.

  The set jig has one or more rectangular polyurethane foam lamp holders fixed to improve one side of the flat plate, and this polyurethane foam is provided with a large number of cuts at a short pitch in the mounting direction of the thin fluorescent lamp. Can be.

  Since thin fluorescent lamps can be fitted into a large number of cuts, the workability is good and the glass tube is not damaged. It can be easily set off-line. In this way, since the thin fluorescent lamp is buried in the polyurethane foam, it is possible to pile up the set jigs that have been set.

  With the above configuration, the thin fluorescent lamp soldering apparatus according to the present invention attaches a plurality of thin fluorescent lamps to the setting jig offline, fixes them to the swivel base whose height is adjusted, and the electrode terminals are It can be swiveled into position and soldered sequentially to each lamp at the top. When soldering to the electrode terminal on the opposite side of the straight tube-type thin fluorescent lamp, the set jig, that is, the thin fluorescent lamp is inverted through the swivel base and soldered to the other electrode terminal on the upper side. can do.

  Since multiple thin fluorescent lamps are arranged in parallel and set on a set jig and swiveled in a vertical plane, a large amount of space is not required, and workability is efficient and efficient soldering work. can do.

  A support base, a turning base that is turnable about a horizontal axis orthogonal to the support post, and a set jig that is detachable from the turn base; According to the thin fluorescent lamp soldering device, which is provided with a lamp locking member capable of arranging the fluorescent lamps in parallel, the bottom area of the device can be minimized regardless of the length of the lamp, The operator can reliably and easily perform the operation in such a posture that the shaped sealing body is in a vertical posture and the protruding direction of the lead wire is upward and the working portion is looked down from above. The direction change in the case where the lamp is a straight pipe is based on the turning-based turning, and thus can be performed easily, safely and efficiently without taking up space and damaging the envelope.

  The swivel-based swivel can be 90 °, 180 ° or 360 ° swivel in the vertical plane, so the soldering worker can turn in any direction clockwise or counterclockwise to redirect the ramp This can be done efficiently without damaging the lamp in a space-saving manner.

  Since the horizontal axis can be adjusted in the vertical height with respect to the column, the height can be adjusted according to the height and posture of the operator, the hand operation is easy, and the soldering operation can be performed reliably.

  The swivel base is provided with a pair of restricting brackets that engage and fix the outer and outer surfaces of both sides of the set jig so that the set jig can be securely fixed to the swivel base and the pair of restrictors Since only the metal fittings are used, the attaching / detaching work is easy.

  The set jig is one in which one or more rectangular polyurethane foam lamp holders are fixed to improve one side of the flat plate, and this polyurethane foam is provided with a large number of cuts at a short pitch in the mounting direction of the thin fluorescent lamp. In such a case, the thin fluorescent lamp can be fixed to the set jig simply by inserting the sealing portion of the thin fluorescent lamp into the cut in a flexible polyurethane foam. Moreover, since the thin fluorescent lamp is embedded in the polyurethane foam, it can be stacked in multiple stages, and the offline preparation and the shipping work after soldering can be performed efficiently. During this time, there is no risk of damaging the thin fluorescent lamp, and product quality can be improved and line efficiency can be improved.

A front table 5 and a rear table 6 are provided. These tables 5 and 6 do not constitute a main part of the present invention, and may be procured separately from the base 2. The height of the tables 5 and 6 is about 1 m when the worker works in a standing posture, and is a little lower than that when the worker sits on a high chair.

  In the middle of the tables 5 and 6, along the back surface of the front table 5, an apparatus main body 7 that constitutes a main part of the present invention is erected.

  As shown in detail in FIG. 2, the apparatus main body 7 includes a stand 8 erected on the base 2, and a turning base 10 that can turn around a horizontal axis 9 orthogonal to the stand. And a setting jig 11 that is detachably attached to the turning base 10.

  The stand 8 includes two parallel support columns 13 in a rectangular frame 12 and a slide base 14 that can be raised and lowered on the support column 13. The slide base 14 can be moved up and down on the column 13 by tightening or loosening a thumbscrew (not shown), and can be fixed at an arbitrary height position.

  A bush 15 is provided on the front surface of the slide base 14 (left front in FIG. 2), and supports the horizontal shaft 9 so as to be rotatable. For example, an appropriate frictional force is applied by a ball plunger or the like, and when no rotational force is applied from the outside, the rotation can be stopped on the spot.

  A flange member 9F is provided in front of the horizontal shaft 9, and an intermediate plate 16 is fixed to the flange member 9F by screws. The swivel base 10 is fixed to the front of the intermediate plate 16 by screws. Therefore, the turning base 10 can turn around the horizontal axis 9 and can be freely adjusted in height by adjusting the height of the slide base 14.

  A pair of restricting metal fittings 17 and 17 are disposed opposite to each other on one center line on the front surface of the turning base 10. The restricting bracket 17 has a lower member 18 fixed to the base 10 substrate and an upper member 19 with a spring that can be retracted in a direction opposite to the lower member 18 by 1 to 2 cm. In a state where the intermediate recesses 11 a and 11 b of the setting jig 11 are fitted, the setting jig 11 is held by the lower surface of the upper member 19 to hold the turning base 10. Accordingly, the upper member 19 can be retracted against the spring, the recesses 11a and 11b of the setting jig 11 can be fitted, and the spring can be returned to fix the setting jig. As shown in FIG. 3, the setting jig is fixed in a state where the setting jig 11 is in a horizontal posture. The setting jig 11 can be removed by the reverse procedure. These work procedures will be described in detail with reference to FIG.

  A pair of lamp holders 20 is provided on the front surface of the setting jig 11 at the end along the longitudinal direction. The lamp holder 20 is formed by pasting a polyurethane foam rectangular material and making a number of cuts 21 in the longitudinal direction. The number of cuts 21 is greater than or equal to the number of lamps arranged in this. In this example, the lamp 22 is fitted to each cut in accordance with 15 lamps, but the way of inserting the cut 21 is not limited to this. A plurality of, for example, 15 thin fluorescent lamps 22 are fitted to the set jig 11 so as to be supported at both ends by each lamp holder 20. This work is not performed in the state of FIG. 1, but is performed off-line on another work table.

  First, a required number of lamps 22 are fixed to the jig base 11 offline. In the example shown in FIG. 2, 15 lamps are fixed between the lamp holders 20 and 20. In a state where the lamp 22 is fitted between the lamp holders 20 and 20, the lamp 22 is buried in the lamp holder 20 made of polyurethane foam. Therefore, a large number of the lamps 22 can be stacked and carried in a bundled state.

  The soldering work table can be attached to the swivel base 10 in the horizontal direction shown in FIG. 3 by picking up one set jig 11 on which the lamp 22 is set. That is, the lower position recess 11a or 11b of the setting jig 11 is dropped into the restriction fitting 17, and the upper member 19 of the upper restriction fitting 17 is retracted upward to fit the upper depression 11a or 11b of the setting jig 11. The set jig 11 can be fixed on the turning base 10 with the two restricting metal members 17 by dropping the upper member 19 of the restricting metal member 17 above from the retracted position.

  Next, by turning the turning base 10 to which the setting jig 11 is attached by 90 ° in an arbitrary direction, as shown in FIG.

As shown in FIG. 5, a soldering operation can be performed. In FIG. 5, the tip conductor portion of the wire harness cord 24 can be applied to the lead wire 25 and soldered by the soldering iron 3. Because it is in the correct posture, work is easy and can be done accurately. Although the wire harness 23 is shown in the example of two sets, it is not limited to this.

  When the operations for the respective lamps 22 are sequentially completed, the setting jig 11 and the turning base 10 can be turned 180 ° from the state shown in FIG. Since one or the other has the same orientation, the work can be performed uniformly.

  When the soldering operation of both ends of the lamp 22 is completed, the turning base 10 can be turned 90 ° again as shown in FIG. 3, the setting jig 11 can be removed from the turning base 10, and the next processing can be performed. When the next process is an assembly operation at another factory, the set jig 11 can be delivered as it is, and the set jig 11 can be collected later. At the time of delivery and assembly, the lamp 22 is protected by the lamp holder 20 made of polyurethane foam, so there is almost no risk of breakage, and high quality control can be performed.

  FIG. 6 shows another application example. In this example, a U-shaped thin fluorescent lamp 26 is attached to the setting jig 11 instead of a straight tube, and one or the other of the setting jig 11 is sequentially directed upward, and soldering is performed on each lamp 26. Is.

  Although the lamp holder 20 is shown as an example in which a cut 21 is formed in polyurethane foam, a rubber material or the like can be used to flexibly support the lamp. Moreover, although the example of the shape which pinches | interposes a setting jig as both ends from the both ends was shown as the control metal fitting 17, the shape which provides a protrusion in the turning base 10 side, and fits the protrusion in the hole provided in the example of a setting jig. It is also good. There is also an example in which a protrusion is provided on the set jig side.
