JP5222114B2 - Component mounting jig and automatic component mounting apparatus using the jig - Google Patents

Description

  The present invention relates to a jig for mounting a large number of components at a specific position such as a board and an automatic component mounting apparatus using the jig, and more particularly to the back of a lamp socket for a light source in a backlight device such as a liquid crystal television. The present invention relates to a jig that can be optimally applied to a light chassis and an automatic insertion device using the jig.

  In recent years, flat-screen televisions such as liquid crystal televisions have become widespread, and price competition has intensified along with competition for larger screens and higher image quality.

  In a liquid crystal television, since the liquid crystal panel itself does not emit light, a backlight unit that supplies light to the liquid crystal panel is usually provided on the back side of the liquid crystal panel. In the backlight unit, a plurality of cold cathode fluorescent tubes called CCFLs are used as light source lamps. This cold cathode fluorescent tube is usually a cylindrical shape with a thickness of several millimeters and has an elongated shape corresponding to the size of the screen.

  FIG. 12 schematically shows a part of the configuration of the backlight unit. In FIG. 12, reference numeral 110 denotes a backlight chassis. The backlight chassis 110 includes a lamp socket 111 for holding the lamp 112 and supplying power to the lamp 112. In FIG. 12, only one end of the backlight chassis 110 is shown, but a similar socket is also provided at the other end, and the lamp 112 is inserted and fixed to the lamp socket 111 at both ends thereof. FIG. 12 shows the lamp 112 before being inserted into the lamp socket 111 and the lamp 112 ′ after being inserted.

  In FIG. 12, three lamp sockets 111 for light source lamps are shown, but an actual television requires a larger number of light source lamps. For example, a 32-inch (32-inch) liquid crystal television normally uses about 12 cold cathode fluorescent tubes. In this case, a total of 24 lamp sockets 111 for light sources are provided at both left and right ends of the backlight chassis. I need it. A 37-inch (37-inch) liquid crystal television normally uses about 20 cold cathode fluorescent tubes. In this case, a total of 40 lamp sockets 111 for light sources are provided at both right and left ends of the backlight chassis. I need it.

  FIG. 13 is a diagram illustrating an example of the lamp socket 111. The lamp socket 111 has, for example, a main body 120 that is 21 mm wide, 12 mm long, and 25.8 mm high and formed in a box shape, and a semicircular opening 121 for storing a lamp provided in the main body 120. And an electrode 122 for supplying power to the lamp provided inside the main body. In FIG. 13, only one power supply electrode 122 is visible, but a power supply electrode 123 (shown by a broken line) is also provided on the opposing side wall portion of the main body 120. Reference numeral 124 denotes a portion that houses a connection for receiving power from an inverter circuit (not shown). When the lamp socket 111 is mounted on the backlight chassis 110, it projects to the back side of the backlight chassis 110. become.

  As simply shown in FIG. 12, the light source lamp 112 is inserted into the box-shaped main body 120 through the opening 121 of the lamp socket 111 and is mechanically sandwiched between the power supply electrodes 122 and 123. At the same time, it receives power from a power supply unit (not shown). Although the shape of the lamp socket is slightly different between FIGS. 12 and 13, there is no difference in the basic functions of holding the lamp and supplying power to the lamp.

  FIG. 14 is a diagram schematically showing how the lamp socket 111 is attached to the backlight chassis 110. In FIG. 14, reference numeral 140 denotes openings provided at both right and left ends of the backlight chassis 110, and the openings 140 serve as backlights for lamp sockets 111 for cold cathode fluorescent tubes that are light sources of the backlight. This is for attaching to the chassis 110. The lamp socket 111 is inserted and fixed in the opening 140 for attaching the lamp socket. Therefore, when a linear cold cathode fluorescent tube as shown in FIG. 12 is used as a backlight light source lamp, the number of openings 140 is (the number of lamps × 2).

  Conventionally, the operation of inserting the lamp socket 111 into the opening 140 has been performed manually. The required number of lamp sockets has increased with the increase in the number of lamps for light sources accompanying the increase in the size of liquid crystal televisions, and this work has also caused an increase in cost. Another important problem of manually performing the lamp socket insertion work is the problem of contamination. That is, in general, the most dust generation source in the assembly process is “people”. However, if this “manual assembly operation” is performed during the assembly operation of the backlight unit, the risk of contamination is increased. If dust enters the backlight unit, the shadow of the dust may be reflected on the liquid crystal display screen. In this case, the image quality is significantly deteriorated.

  In addition, in order to make the brightness of the liquid crystal display screen constant when the backlight unit is assembled to the liquid crystal panel, the interval between the lamps for the light source may be adjusted. In this case, the interval between the lamp sockets 111 should be uniform. It is a bottleneck in realizing automatic assembly.

  Japanese Patent Application Laid-Open No. 2004-151867 discloses a technique that facilitates assembly work of a backlight unit including a lamp socket. FIG. 15 is a diagram showing a mounting state of the lamp socket disclosed in Patent Document 1. In FIG. 15, reference numeral 150 denotes a bottom chassis (corresponding to the backlight chassis 110 in FIGS. 12 and 14) shown with a part omitted, and a plurality of lamp sockets 151 are arranged at the end thereof. ing. In FIG. 15, the lamp socket 151 is shown only at one end (the right end in FIG. 15) of the bottom chassis 150, but actually, it is also provided at the other end (the left end in FIG. 15) of the bottom chassis 150. . The lamp socket 151 is provided at one end of a storage container 152 having an inverter storage part 153 in the lower part. Therefore, the storage container 152 having the lamp socket 151 is also provided at the other end of the bottom chassis 150.

The lamp socket 151 is attached to the end of the storage container 152 before the storage container 152 is attached to the bottom chassis 150. A socket insertion portion (not shown) for attaching the lamp socket 151 is provided at the end of the storage container 152 in advance, so that the lamp socket 151 can be easily attached. Further, since the storage container 152 itself is relatively small and easy to handle, it is easy to attach the lamp socket 151 and store the inverter, and is suitable for automation.
JP 2008-153218 A (published July 3, 2008)

  As described above, Patent Document 1 describes that the lamp socket 151 can be easily attached to the storage container 152 and is suitable for automation, but a specific apparatus for automation is described. It has not been. Therefore, the attachment of the lamp socket 151 to the storage container 152 still relies on manual work. In this case, there arises a problem of cost and a problem of deterioration of image display quality of the liquid crystal panel due to dust mixing.

[Embodiment 1]
An embodiment of the present invention will be described with reference to FIGS. In the following description, an example in which the present invention is applied to a lamp socket automatic mounting apparatus in a backlight unit such as a liquid crystal television is used, and various technically preferable limitations are imposed to implement the present invention. However, the scope of the present invention is not limited to the following embodiments and drawings.

  In the following description, first, an outline of an automatic component mounting apparatus according to the present invention will be described with reference to FIGS. 1, 2, and 3, and a large number of components according to the present invention will be described with reference to FIGS. Details of a jig for mounting at a specific position such as the above and a component automatic mounting apparatus using the jig will be described. Further, the operation of the entire component automation apparatus according to the present invention will be described with reference to FIG. In FIG. 1 to FIG. 9, the same members are assigned the same numbers, and detailed descriptions of the members are omitted for each drawing.

  FIG. 1 is a perspective view schematically showing the entire component automatic mounting apparatus according to the present invention, and particularly shows an example applied to an automatic mounting apparatus for a lamp socket in a backlight unit of a liquid crystal display device. 2 is a side view of the lamp socket automatic mounting apparatus shown in FIG. 1, and FIG. 3 is a top view of the main part of the lamp socket automatic mounting apparatus as viewed from above.

  1, 2, and 3, reference numeral 10 denotes an entire lamp socket automatic mounting apparatus. FIG. 1 schematically shows an enlarged lamp socket 15 and three backlight chassis 16 to which the lamp socket 15 is attached. The lamp socket automatic mounting device 10 mainly includes four parts: a parts feeder section 1, an alignment feeder section 2, a lamp socket arbitrary interval alignment section 3, and a lamp socket batch mounting section 4.

  The parts feeder unit 1 includes a parts supply unit 11 and a parts alignment unit 12. The lamp socket 15 is supplied from the parts supply unit 11 to the parts alignment unit 12 in a disjointed posture, and is aligned in a certain direction in the parts alignment unit 12. The lamp sockets 15 aligned in a certain direction are sent to the alignment feeder unit 2.

  The aligning feeder section 2 is inserted into one backlight chassis 16 from the lamp socket group 22 (see FIG. 3) aligned and aligned in a certain direction by the parts aligning section 12 (one lamp usually includes both lamps). Two lamp sockets are required, one for each side, so the backlight chassis can have twice as many lamp sockets as the number of lamps to be installed. This is the part that separates the lamp socket group 23 of the same number of lamp sockets as the number of lamp sockets on one side of the lamp because automatic mounting of the lamp sockets is required for each side. The predetermined number of lamp socket groups 23 separated is sent to the next lamp socket arbitrary interval alignment unit 3. The aligning feeder unit 2 is provided with a parts transporting cage 21, and the lamp socket is sent to a predetermined position of the lamp socket arbitrary interval aligning unit 3 while maintaining the posture on the parts transporting cage 21.

  The lamp socket arbitrary interval alignment unit 3 is a portion that aligns a predetermined number of lamp sockets 15 aligned in one direction at an arbitrary interval so as to correspond to the socket installation position of the backlight chassis 16. As already described, the lamps provided in the backlight chassis 16 are not necessarily arranged at regular intervals, but are adjusted according to the screen size or the like so that the display brightness on the liquid crystal display screen is constant. . As described in detail later, the lamp socket arbitrary interval aligning unit 3 can align the lamp socket 15 at an arbitrary predetermined interval even when the interval is not constant.

  The lamp socket batch mounting portion 4 is a portion for mounting a predetermined number of lamp sockets 15 aligned with the socket installation position of the backlight chassis 16 to the backlight chassis 16. As will be described in detail later, the lamp lamps 15 provided in the backlight chassis 16 can be obtained by collectively grasping and moving in parallel the “lamp sockets 15 aligned with the socket installation position of the backlight chassis 16”. Insert and fasten to the socket mounting opening.

  The lamp socket automatic mounting apparatus 10 includes an assembly conveyor 5 that conveys a backlight chassis 16 into which the lamp socket 15 is to be assembled, a base 6 on which the parts feeder 1 and the alignment feeder 2 are placed, and an arbitrary interval alignment section for the lamp socket. 3 and the like, and a belt conveyor base 8 that holds the belt conveyor 5.

  When the lamp sockets 15 are attached to the left and right ends of the backlight chassis 16, the directions of the lamp sockets 15 are different on the left and right. Therefore, for example, two lamp socket automatic mounting apparatuses 10 are arranged in a column, and first, the lamp socket 15 is mounted on one end of the backlight chassis 16 by one lamp socket automatic mounting apparatus 10, and then It is preferable from the viewpoint of efficient work that a lamp socket is attached to the other end. Of course, the lamp socket 15 may be mounted by passing the backlight chassis 16 twice using the single lamp socket automatic mounting apparatus 10.

  FIG. 3 shows the configuration of the parts feeder unit 1, the alignment feeder unit 2, and the lamp socket arbitrary interval alignment unit 3 in more detail. The parts feeder 1 can be of various known types, but the illustrated one is a so-called vibration type.

  A plurality of lamp socket groups 22 aligned in a certain direction and a lamp socket group 23 cut into a predetermined number are shown on the parts transporting cage 21 of the alignment feeder section 2. Further, a predetermined number of lamp socket groups 23 have been moved to a predetermined position 24 of the lamp socket arbitrary interval alignment unit 3.

  First, the detailed configuration and operation of the alignment feeder unit 2 will be described with reference to FIG. 4, and then, the detailed configuration and operation of the lamp socket arbitrary interval alignment unit 3 will be described with reference to FIGS. Finally, the detailed configuration and operation of the lamp socket batch mounting portion 4 will be described with reference to FIGS. 7, 8, and 9.

  4 (a), (b), (c), and (d) show a situation where a predetermined number of lamp sockets 15 are separated, and FIG. 4 (e) shows the parts transport described in FIG. The details of the jar 21 are shown. 4 (a), (b), (c), (d), and (e), reference numeral 21 denotes a parts transporting cage for transporting parts such as lamp sockets, and FIGS. ), (C), and (d), the parts transporting cage 21 is represented by a single line in order to simplify the drawing. As shown in the perspective view of FIG. 4 (e), the actual structure is composed of, for example, two plate-like holding members arranged in parallel with a predetermined distance d. Thereby, the lamp socket 15 can be moved in the left-right direction while maintaining its posture. Reference numeral 25 denotes a cylinder rod configured to be movable up and down, left and right, 26 denotes a plate attached to the tip of the cylinder rod 25, and 27 denotes a stopper for restricting movement of the lamp socket 15.

  As shown in FIG. 4A, the lamp socket 15 supplied from the parts aligning unit 12 moves on the parts transporting cage 21 and is stopped by the stopper 27, and the lamp socket 15 is placed on the parts transporting kit 21. Stored as group 22. Next, as shown in FIG. 4B, the cylinder rod 25 is lowered downward with respect to the lamp socket group 22 in this state, and the plate 26 separates a predetermined number of lamp socket groups 23. When the lamp socket group 23 is separated, the stopper 27 is removed, and the separated lamp socket group 23 is moved rightward in the drawing by the cylinder rod 25 as shown in FIG. Set to the position of.

  This position is a lamp socket initial setting position in the lamp socket arbitrary interval alignment section 3 indicated by numeral 24 in FIG. After the lamp socket group 23 is set to the initial setting position 24, as shown in FIG. 4D, the cylinder rod 25 is moved upward and simultaneously moved to the left in the drawing. The position is returned to the position shown in a) to prepare for the next lamp socket group sorting operation.

  Various changes can be made to the alignment feeder unit 2. For example, the cylinder rod 25 may be configured to be rotatable about the longitudinal direction of the cylinder rod 25, and the hooking operation on the plate 26 lamp socket in the sorting operation of the lamp socket group 23 may be performed by rotating the cylinder rod. Alternatively, after the predetermined number of lamp socket groups 23 are cut out, the lamp socket groups 23 may be sucked and held on the cylinder rods so as to be movable integrally with the cylinder rods.

  When a certain number of lamp socket groups 23 are attracted and held by the cylinder rod 25, the lamp socket group 23 is rotated in the plane in FIG. The lamp socket can be supplied to a predetermined position of the arbitrary interval alignment unit 3. Therefore, in this case, if the lamp socket group 23 is supplied to the lamp socket arbitrary interval alignment unit 3 by alternately changing the direction of the lamp socket group 23, the backlight chassis in the single lamp socket automatic mounting device 10 can be used. By passing 16 once, the lamp sockets can be attached to the left and right ends of the backlight chassis. The configuration of this example will be described later as a third embodiment with reference to FIG.

  5 and 6 are diagrams showing details of the configuration of the lamp socket arbitrary interval alignment unit 3. As shown in FIGS. 5 and 6, the lamp socket arbitrary interval alignment unit 3 includes a holding unit 31 for aligning and holding the lamp socket 15 so as to be movable in the horizontal direction of the drawing, and the holding unit 31 integrated with the lamp socket 15. A second cylinder rod 32 for moving in the vertical direction, a second stopper 33 for setting a predetermined number of lamp socket groups 23 at a predetermined position 24, and guiding the lamp socket 15. A guide 34 is provided. The holding unit 31 may basically have the same configuration as the part transporting cage 21 described with reference to FIGS. 3 and 4, but in accordance with the pushing operation of the second cylinder rod 32 in the lamp socket arbitrary interval alignment unit 3. , It is configured to be movable in the direction of arrow 36.

  As shown in detail in FIG. 6, the guide 34 includes a plurality of plate-like guides 34-1, 34-2,... 34-n, and a pair of guides, for example, 34-1 and 34-2, Thus, a guide passage 35-1 is formed. The lamp socket 15 is guided in a predetermined direction along the guide path 35-1 as the holding portion 31 moves. The intervals of the guide passages 35-1,... 35-n with respect to the individual lamp sockets 15 are gradually adjusted, and finally, at the position 37, each lamp socket 15 is configured to have a predetermined interval. Keep it. The letters on the front of the lamp socket set at the final position 37 in FIG. 5 indicate the lamp socket arrangement interval.

  The position of the lamp group 23 set in a predetermined position 24 by being moved in the horizontal direction in the drawing by the cylinder rod 25 on the holding portion 31 of the lamp socket arbitrary interval aligning portion 3 is accurately regulated by the second stopper 33. Is done. That is, as shown in FIG. 6, each lamp socket 15 is set at a position facing the guide passages 35-1,... 35-n formed by a pair of guide plates.

  When the second cylinder rod 32 is driven in this state to move the entire holding portion 31 in the vertical direction (in the direction of the arrow 36), each lamp socket 15 held by the holding portion 31 is guided to the guide passage 35-1. ,..., 35-n, moving in the direction of the arrow while maintaining the posture. Since the guide passages 35-1,... 35-n are configured to gradually change their positions in the width direction, each lamp socket 15 is laterally (in the direction of the arrow 38) on the holding portion 31. Will also move. At the position 37, the lamp sockets 15 are set at predetermined intervals between the lamp sockets. As is clear from the above description, the distance between the lamp sockets can be arbitrarily set by guiding the guide passages 35-1,... 35-n in any direction.

  Since the operation of the lamp socket arbitrary interval aligning portion 3 can be basically achieved only by reciprocating motion, the structure of the lamp socket arbitrary interval aligning portion 3 can be extremely simplified. In addition, when the interval between the lamp sockets is changed, it is only necessary to change the guide 34. Therefore, it is very easy to cope with an arbitrary interval. The lamp socket arbitrary interval alignment unit 3 is also extremely useful as a single component mounting jig for arranging general components at arbitrary intervals. For example, when the components arranged at arbitrary intervals are bonded together It is clear that it can be used effectively.

  In addition, parts can be inserted using a robot, etc. (1) It is possible to position the parts in advance, so there is no need to detect the exact location of the parts. Therefore, a required operation can be performed only by a certain distance of movement, and the operation for the robot operation can be simplified. This is extremely useful for simplifying the robot operation.

  7, 8 and 9 are diagrams for explaining the configuration and operation of the lamp socket batch mounting portion 4. FIG. 7 shows a state in which the lamp sockets 15 are set on the holding portion 31 at a predetermined interval, and FIG. 8A shows a cap for picking up the lamp sockets 15 arranged at the predetermined interval in a lump. The configuration of the king mechanism 41 is shown, and FIG. 8B shows a state in which the caching mechanism 41 holds the lamp socket 15. 9A, 9 </ b> B, 9 </ b> C, 9 </ b> D, and 9 </ b> E are diagrams for explaining a series of operations of the lamp socket batch mounting portion 4 that mainly uses the operation of the caching mechanism portion 41. It is. On the right side of FIGS. 9A, 9B, 9C, 9D, and 9E, there are further step-by-step explanatory diagrams (s1) to (s9) for explaining details of a series of operations. It is shown.

  As shown in FIG. 8, the lamp socket batch mounting portion 4 includes a caching mechanism portion 41 for picking up a large number of lamp sockets 15 in a lump. A lampholder support rod 42 is provided. The interval between the lamp socket support bars 42 is configured to be the same as the interval between the lamp sockets attached to the backlight chassis 16. The lamp socket support bar 42 is formed in the same shape as the electrode portion of the lamp inserted into the lamp socket, and can be inserted between the power supply electrodes 81 and 82 of the lamp socket 15.

  When the caking mechanism 41 holds the lamp socket 15, the lamp socket support bar 42 may be inserted between the power supply electrodes 81 and 82 of the lamp socket 15 as shown in FIG. . The lamp socket batch mounting portion 4 has a drive mechanism for moving the above-described caching mechanism portion 41 in the vertical direction (arrow 45 direction) or the front-rear direction (arrow 46 direction), although not shown in the drawings. ing.

  With reference to FIG. 9, a series of operation | movement of the lamp socket batch mounting part 4 is demonstrated. FIG. 9A shows a situation where a plurality of lamp sockets 15 are arranged on the holding unit 31 of the lamp socket arbitrary interval alignment unit 3 at a predetermined interval. In step 1 (see s 1) of FIG. 9A, the caching mechanism portion 41 placed at the initial position is moved in the direction of the arrow 91 and is positioned directly above the lamp socket 15 aligned with the holding portion 31. Set (see s2).

Next, in this state, the caching mechanism 41 is moved downward (ie, in the direction of the arrow 92) (see s3), and as shown in FIG. 9B, the lamp socket support bar 42 of the caching mechanism 41 is moved to the lamp. The socket 15 is engaged (see s4). As a result, the lamp socket 15 is held by the cucking mechanism 41. Next, the caching mechanism unit 41 is moved upward (in the direction of arrow 93) while holding the lamp socket 15, and as a result, the lamp socket 15 is separated from the holding unit 31 (see s5). The lamp socket 15 (see s6) separated from the holding portion 31 and integrated with the cucking mechanism portion 41 is moved in the direction of the arrow 94, and the lamp socket mounting opening of the backlight chassis 16 shown in FIG. It is set on the part 50 (see s7).

  After the lamp socket 15 is set on the lamp socket mounting opening 50 of the backlight chassis 16, the caching mechanism 41 is moved downward (in the direction of the arrow 95) while holding the lamp socket 15, and FIG. As shown in d), it is fitted into the lamp socket mounting opening 50 of the backlight chassis 16 (see s8).

  After the lamp socket 15 is fitted into the lamp socket mounting opening 50 of the backlight chassis, the engagement between the cucking mechanism 41 and the lamp socket 15 is released. That is, as shown in step 9 (see s9) of FIG. 9 (e), first, the locking mechanism 41 is slid in the lateral direction (in the direction of arrow 96) to engage the lamp socket 15 with the lamp socket support bar 42. Then, the caking mechanism 41 is moved upward (in the direction of arrow 97). Even when the caching mechanism 41 is moved in the lateral direction (in the direction of arrow 96), the lamp socket 15 is fitted in the opening 50, so that it does not move while being held by the backlight chassis 16. The part 41 and the lamp socket 15 are easily separated.

  In this way, the lamp socket 15 can be attached to the lamp socket attachment opening 50 of the backlight chassis 16. The interval between the lamp socket mounting openings 50 may be arbitrary, and the number may be arbitrary.

[Embodiment 2]
FIG. 10 is a diagram showing Embodiment 2 of the present invention. In the second embodiment, the guide 34 for guiding the lamp socket 15 to an arbitrary position can be exchanged in the lamp socket arbitrary interval aligning section 3 so that the lamp socket can be automatically mounted in a plurality of types of backlight units. I have to.

  In FIG. 10, 34A and 34B are guides for guiding the lamp socket 15 to a predetermined position, but are of different types depending on the interval between the lamp sockets to be set on the backlight chassis.

  If the guide 34A set at the position 100 in FIG. 10 is used as the guide for the backlight chassis A currently mounted with the lamp socket, the backlight chassis is automatically inserted into the backlight chassis B of another model. A guide 34B corresponding to B may be used. For example, this can be easily achieved by making the guide movable in the lateral direction as shown in the drawing. In particular, by enabling automatic replacement, it is possible to allow different types of devices to flow on a single line, and to respond to high-mix low-volume production.

[Embodiment 3]
11 (a), (b), (c), and (d) are diagrams showing Embodiment 3 of the present invention. In this Embodiment 3, it is set as the structure which can change easily the direction of the front-back direction of a lamp socket as needed. In FIG. 11, the same members as those shown in FIGS. 4, 6 and the like are assigned the same numbers as those in FIGS. 4 and 6. FIG. 11 shows that a necessary number of lamp socket groups 23 are taken out from the lamp socket group 22 arranged on the parts transporting cage 21 and the lamp socket group 23 is placed on the lamp socket holding portion 31 in the lamp socket arbitrary interval alignment portion. An outline of a mechanism for setting in a desired direction is shown.

  11 (a), 11 (b), 11 (c), and 11 (d), 101 is a cylinder rod configured to be movable up and down, left and right, and further rotatable at least 180 degrees. An adsorption jig 102 for adsorbing the socket group 23 is provided. Various means can be used for the suction. For the suction of the lamp socket, for example, a vacuum suction device is suitable. If the component to be held is a magnetic material, an electromagnet or the like can be used.

  The operation when the lamp socket is set on the lamp socket holding portion 31 in a desired direction will be described below.

  First, in FIG. 11 (a), in order to take out a desired number of lamp socket groups 23 from the lamp socket group 22 arranged at a predetermined position on the parts transporting cage 21 by the stopper 27, a suction jig is attached to the tip. The cylinder rod 101 having 102 is lowered downward as shown by the arrow. The number of suction portions of the suction jig is adjusted in advance to the required number of sockets, and only the required number of sockets 23 can be sucked.

  Next, as shown in FIG. 11B, the cylinder rod 101 is moved upward, and further moved rightward in the drawing. At this time, the stopper 27 may be lowered. In this case, it goes without saying that the upward and rightward movements may be performed simultaneously. As shown in FIG. 11 (c), after the cylinder rod 101 is set at a predetermined position of the lamp socket holding portion 31 in the lamp socket arbitrary interval alignment portion, the cylinder rod 101 is rotated as necessary in the longitudinal direction of the lamp. Change the direction and lower it downward. As a result, as shown in FIG. 11D, the socket group 23 can be set at a predetermined position on the lamp socket holding portion 31 in the lamp socket arbitrary interval alignment portion. After completion of the setting, the cylinder rod 101 is moved leftward in the drawing and returned to the initial state. Note that a new socket group 22 'is set to the stopper 27 position during the above operation.

  In the above description, the lamp socket has been particularly described as an example. However, it is apparent that the present invention can be applied not only to the lamp socket but also to general parts.

  The present invention is not limited to the above-described embodiments. Those skilled in the art can make various modifications to the present invention within the scope of the claims. That is, a new embodiment can be obtained by combining appropriately changed technical means within the scope of the claims.

  The component mounting jig and the component automatic mounting apparatus using the jig according to the present invention are extremely useful for manufacturing a product that uses many identical components such as a lamp socket of a liquid crystal television. Industrial applicability is high.
