Description

  The present invention relates to a device for placing components such as electronic components, and more particularly to a component placement device suitable for use in an electronic component mounting device for mounting and mounting electronic components at predetermined positions on the surface of a printed wiring board. The present invention relates to an assembly method, a repair method, and a maintenance management (maintenance) method.

  2. Description of the Related Art Conventionally, an electronic component mounting apparatus has been used to mount an electronic component by placing it at a predetermined position on the surface of a printed wiring board. The electronic component mounting apparatus usually includes a shaft bar (temporary holding means for the placement target component) that temporarily holds the component to be arranged at the lower end, a shaft rod lifting and lowering drive means, and a shaft rod rotation drive means. A component placement device is incorporated. As the temporary holding means for the placement target component, for example, a hollow shaft rod connected to a decompression device (a mechanism for temporarily holding the placement target component) or electromagnetic attaching / detaching means is used.

  When mounting the electronic component, the electronic component mounting apparatus first moves the component placement device above the tray in which the electronic component is accommodated. The component placement device lowers the shaft rod, operates the decompression device to hold the electronic component on the lower end portion of the shaft rod by suction or the like, and then raises the shaft rod. Next, the electronic component mounting apparatus moves the component placement apparatus above a separately prepared printed wiring board. At this time, the component placement apparatus rotates the electronic component together with the shaft rod and directs the electronic component in a predetermined direction. Then, the component placement device lowers the shaft rod, raises the shaft rod after placing the electronic component held on the lower end portion thereof at a predetermined position on the surface of the printed wiring board. By repeating such an operation, a large number of electronic components are mounted on the surface of the printed wiring board.

  In order to enable the rotation of the shaft rod, the shaft rod is accommodated and supported by a cylindrical linear motion bearing, and the shaft rod, for example, a power transmission such as a belt mounted around the linear motion bearing. A rotary drive is connected via the means.

  Patent Document 1 discloses a component placement device (head unit) including a plurality (eg, 10) of shaft rods (drive shafts). A rotary drive device (drive motor) is connected to the shaft rod of the component placement device of the same document via a belt.

JP 2009-170525 A (FIGS. 2 and 3 and paragraph [0043])

  When the shaft rod of the component placement device is repeatedly raised and lowered over a long period of time, the surface of the shaft rod is worn, so that the support of the shaft rod by the linear motion bearing becomes unstable. For this reason, the positioning accuracy when the electronic component held by the shaft rod is arranged on the surface of the printed wiring board is lowered. Therefore, it is necessary to replace the shaft rod that has caused a problem due to wear due to long-term use with another shaft rod such as a new shaft rod.

  However, in the conventional component placement device, when removing the shaft rod provided in the component placement device for replacement, the linear motion bearing that supports the shaft rod and the rotary drive device are connected, for example, When a power transmission means such as a belt is removed, or when another shaft rod is newly attached to the component placement device, the linear motion bearing that supports this shaft rod and the rotary drive device are re-tensioned. In some cases, it is necessary to transfer and connect to each other. Since such operations are complicated and time-consuming, it is a problem to reduce the operating rate of the electronic component mounting apparatus.

  Or, for example, when one of the plurality of shaft rods included in the component placement device is bent due to a collision with a surrounding mechanical device or the like and breaks down, the remaining shaft rod is not replaced. In some cases, mounting of electronic components may be continued using a normal (non-failed) shaft rod. This is to avoid stopping the operation of the electronic component mounting apparatus for a long time due to the replacement of the shaft rod. However, since the number of shaft rods that can be used for mounting is reduced, the mounting efficiency of electronic components is reduced.

FIG. 1 is a perspective view showing a configuration example of a component placement device of the present invention, and FIG. 2 is a side view of the component placement device 10 of FIG.

  The component placement apparatus 10 of the present invention shown in FIGS. 1 and 2 is connected to a frame 11, a temporary holding means for a placement target component mounted on the frame 11 so as to be movable up and down via a rotation means, and the rotation means. An arrangement target component temporary holding device provided with the first power transmission means 17 and a second power transmission means 42 engaged with the first power transmission means 17 are provided, and the frame body 11 is detachable. The base 41 is supported.

  The temporary holding means for the placement target component enables temporary holding of the placement target component. In the case of the component placement device 10 shown in FIGS. 1 and 2, the placement target component is temporarily stored. The shaft rod 12 is connected to a holding mechanism (for example, a pressure reducing device).

  The rotation means described above allows the temporary holding means for the placement target part to be rotated and moved up and down while temporarily holding the placement target part. In this case, it corresponds to a linear motion bearing (for example, a linear motion bearing 14a) that supports the shaft rod so as to be movable up and down, and a rotary bearing 15 that rotatably supports the linear motion bearing together with the shaft rod 12.

  The arrangement target component temporary holding device includes the frame, the temporary holding unit of the arrangement target component mounted on the frame via the rotation unit, and the first power transmission unit as described above. In the case of the component placement device 10 shown in FIGS. 1 and 2, the shaft 11 connected to the frame 11, the linear motion bearing and the rotary bearing 15, and a mechanism (for example, a decompression device) that temporarily holds the placement target component. , And a shaft bar up-and-down rotation mechanism 19 including the first power transmission means 17.

  In the component placement device of the present invention, the base may further be provided with a lifting drive means for temporarily holding the placement target parts. The raising / lowering drive means moves up and down the temporary holding means for the placement target component. In the case of the component placement device 10 shown in FIGS. 1 and 2, a mechanism for temporarily holding the placement target component (for example, a decompression device). It corresponds to the lift drive means 44 that lifts and lowers the shaft rod 12 connected to.

  In the component placement apparatus of the present invention, means for driving and controlling the raising / lowering of the temporary holding means for the placement target parts may be further provided on the base instead of the above-described raising / lowering driving means. As means for driving and controlling the raising and lowering of the temporary holding means for the component to be arranged, for example, means for driving the shaft rod upward (for example, an elastic body such as a spring) and the top of the shaft rod downward A combination of pressing means for controlling the vertical position of the shaft rod can be used.

  Below, the structure of the component arrangement | positioning apparatus 10 of FIG.1 and FIG.2 which is a preferable embodiment of the component arrangement | positioning apparatus of this invention is demonstrated in detail.

  The component placement device 10 is connected to a frame 11, a shaft rod 12 connected in parallel to the frame body 11 and connected to a mechanism (not shown) that temporarily holds a placement target component, and the shaft rod 12 can be moved up and down. A plurality of shaft rod lifting and lowering rotation means 16 (for example, a linear motion bearing 14a) including a cylindrical body 13 supported on the shaft and a rotary bearing 15 mounted around the cylindrical body 13 of the linear motion bearing (for example, , 6), and a shaft bar lifting / lowering rotation mechanism 19 supported by the frame 11 and connected to each of the shaft bar lifting / lowering rotation means 16 via the first power transmission means 17. The rotation drive means 43 connected to the second power transmission means 42 detachably engaged with the rotation transmission means 18 of the shaft rod up-and-down rotation mechanism 19 and the shaft rod 12 of the shaft rod up-and-down rotation mechanism 19 Elevating drive means 44 arranged in contact with the upper end is provided. Includes a base 41, it has a configuration in which the frame body 11 of the axle lifting rotation mechanism 19 is detachably fixed and supported on the base 41.

  For example, the component placement apparatus 10 simultaneously adsorbs six components housed in a tray to the lower end portion of each shaft rod 12 and rotates these components together with the shaft rod 12 to place them in a predetermined direction. It is used by being incorporated in a device that is arranged (accommodated) on a tray different from the above.

  Next, the configuration of the shaft rod up-and-down rotation mechanism 19 provided in the component placement device 10 will be described.

  FIG. 3 is a perspective view of a shaft bar up-and-down rotation mechanism 19 provided in the component placement device 10 of FIG. FIG. 4 is a cross-sectional view of the shaft rod lifting / lowering rotating means 16 at the right end of the shaft rod lifting / lowering rotating mechanism 19 of FIG. 3 cut along the cutting line IV-IV. FIG. 5 is a diagram schematically showing the configuration of the first power transmission means 17 and the rotation transmission means 18 of the shaft rod up-and-down rotation mechanism 19 shown in FIG.

  The shaft rod up-and-down rotation mechanism 19 includes a shaft rod 12, a linear motion bearing 14a including a cylindrical body 13 that supports the shaft rod 12 so as to be movable up and down, and a rotary bearing 15 mounted around the cylindrical body 13 of the linear motion bearing 14a. A plurality of (for example, six) shaft rod lifting and lowering means 16 including The plurality of shaft rod lifting / lowering means 16 are supported in parallel to the frame body 11.

  As the number of the shaft rod lifting / lowering means 16 increases, components can be arranged more efficiently. However, the configuration of the shaft rod lifting / lowering mechanism 19 becomes complicated. Therefore, the number of the shaft rod lifting / lowering means 16 is normally set to a number in the range of 2 to 50 (preferably 4 to 20).

  The shaft rod 12 of each shaft rod lifting / lowering rotation means 16 extends in the vertical direction, and a part to be arranged is temporarily held at the lower end portion of the shaft rod 12. The shaft 12 is connected to a mechanism (not shown) that temporarily holds the component to be arranged.

  As a mechanism for temporarily holding the component to be placed, the same mechanism as that of a known component placement device can be used. For example, a decompression device (eg, a known pump represented by an ejector vacuum pump), or An electromagnet can be used.

  The shaft rod 12 of the shaft rod lifting / lowering rotation mechanism 19 is hollow, and the upper end portion of the shaft rod 12 is connected to a decompression device (not shown) via a gas passage 31m of a shaft rod support 31 described later. Has been. Then, by operating the above-described decompression device, it is possible to suck (temporarily hold) the component to be placed on the lower end of the shaft 12. It is also possible to fix the suction nozzle to the lower end portion of the shaft rod and connect a decompression device to the side surface of the suction nozzle (that is, connect the shaft rod to the decompression device via the suction nozzle). In this case, the shaft rod need not be hollow.

  The linear motion bearing 14a includes a cylindrical body 13 that supports the shaft 12 so as to be movable up and down.

  A plurality of (for example, four) grooves 12 a are formed on the outer peripheral surface of the shaft rod 12 at intervals in the circumferential direction, and the grooves 12 a of the shaft rod 12 are formed on the inner peripheral surface of the cylindrical body 13. A plurality of opposing grooves 13a are formed. A plurality of rolling elements (for example, spheres) 21 are accommodated between the grooves 12 a of the shaft rod 12 and the grooves 13 a of the cylindrical body 13. Since the rolling element 21 engages with each of the groove 12 a of the shaft 12 and the groove 13 a of the cylinder 13, rotation of the shaft 12 in the circumferential direction with respect to the cylinder 13 is limited.

  As the linear motion bearing 14a, a known linear motion bearing that restricts the rotation of the shaft rod in the circumferential direction with respect to the cylindrical body can be used.

  The configuration of the linear motion bearings 14b, 14c, 14d, 14e, and 14f is the same as that of the linear motion bearing 14a.

  A known rotary bearing 15 is mounted around the cylinder 13 of each linear motion bearing. As shown in FIG. 4, a plurality of (for example, two) rotary bearings 15 can be mounted around the cylindrical body 13.

  When the linear motion bearing supported by the rotary bearing 15, for example, the cylindrical body 13 of the linear motion bearing 14 a is rotated in the circumferential direction, the rotation of the shaft 12 in the circumferential direction relative to the cylindrical body 13 is limited as described above. Therefore, the shaft rod 12 supported by the linear motion bearing 14a can be rotated in the circumferential direction.

  The frame 11 of the shaft rod lifting / lowering mechanism 19 supports rotation transmission means 18 connected to the shaft rod lifting / lowering rotation means 16 via the first power transmission means 17.

  The rotation transmitting means 18 includes pulleys (eg, timing pulleys) 18a and 18b.

  The first power transmission means 17 is disposed below the upper plate 11a of the frame body 11, and is engaged with a pulley (not shown) mounted around the rotation shaft of the pulley 18a. Belts (e.g., timing belts) 17a and 17b, similarly, a pulley (not shown) disposed below the upper plate 11a of the frame 11 and mounted around the rotation shaft of the pulley 18b. Belts 17c and 17d that are engaged with each other, and a pulley 17e that is mounted around the cylinder 13 of the linear motion bearing of each shaft rod up-and-down rotating means 16.

  The belt 17a is mounted on the pulley 17e mounted around the cylindrical body 13 of each of the linear motion bearings 14a and 14b, and the belt 17b is mounted on the periphery of each cylindrical body 13 of the linear motion bearings 14b and 14c. The pulley 17e has a belt 17c on the pulley 17e mounted around the cylindrical body 13 of each of the linear motion bearings 14d and 14e, and the belt 17d extends around the cylindrical body 13 of each of the linear motion bearings 14e and 14f. The pulley 17e is engaged.

  Accordingly, by rotating the pulley 18a of the rotation transmission means 18, each of the linear motion bearings 14a, 14b, 14c connected to the rotation transmission means 18 via the belts 17a, 17b of the first power transmission means 17 is achieved. In total, the three shaft rods 12 supported can be rotated simultaneously. Similarly, by rotating the pulley 18b of the rotation transmission means 18, each of the linear motion bearings 14d, 14e, 14f connected to the rotation transmission means 18 via the belts 17c, 17d of the first power transmission means is obtained. In total, the three shaft rods 12 supported can be rotated simultaneously.

  On the other hand, as shown in FIGS. 3 and 4, each shaft rod 12 is supported by a shaft rod support 31. These shaft bar supports 31 are fixed to each other via a connecting bar 32. By raising and lowering the connecting rod 32, a total of six shaft rods 12 can be raised and lowered simultaneously.

  The shaft rod support 31 includes a cylindrical body 31a that grips the upper end of the shaft rod 12, a rotary bearing 31b that rotatably supports the cylindrical body 31a together with the shaft rod 12, a cylindrical body 31c that is mounted around the rotary bearing 31b, The connecting member 31d provided at the upper part of the cylindrical body 31c, the case 31e installed at the upper part of the connecting member 31d, the spherical body 31g having the screw shaft 31f at the top, and the top and bottom of the spherical body 31g. The two annular bodies 31h that can be finely moved in the radial direction are formed.

  For example, if the shaft rod 12 is directly connected and fixed to the connecting rod 32 without using the shaft rod support 31, the center of the top of the shaft rod 12 fixed to the connecting rod 32 and the frame If the center of the opening 22a of the upper plate 11a of the body 11 and the center of the opening 22b of the lower plate 11b are not precisely aligned, the shaft 12 may be slightly curved. Therefore, when the shaft rod 12 is raised and lowered over a long period of time, the outer peripheral surface of the shaft rod 12 or the inner peripheral surface of the cylinder 13 of the linear motion bearing that supports the shaft rod is unevenly worn, and the shaft rod Alternatively, it is necessary to replace the linear motion bearing at an early stage.

  On the other hand, when the shaft rod 12 is connected to the connecting rod 32 via the shaft rod support 31, the spherical body 31g of the shaft rod support 31 can rotate slightly inside the case 31e, and the above-mentioned The ring body 31h can move slightly in the radial direction of the ring body 31h. For this reason, since the upper end portion of the shaft rod 12 is not firmly fixed to the connecting rod 32, the bending of the shaft rod 12 as described above can be suppressed. Accordingly, uneven wear of the outer peripheral surface of the shaft rod 12 or the inner peripheral surface of the cylindrical body 13 of the linear motion bearing supporting the shaft rod is suppressed, and therefore the frequency of replacement of the shaft rod or the linear motion bearing is reduced. Can do.

  An annular packing 31k is provided between the cylindrical body 31a and the cylindrical body 31c. The packing 31k operates the decompression device connected to the gas passage 31m to decompress the inside of the shaft rod 12, and when the components to be arranged are adsorbed to the lower end portion of the shaft rod 12, the both cylinders 31a described above. , 31c to prevent the outside air from flowing into the gas passage 31m.

  Next, the structure of the base 41 of the component placement apparatus 10 shown in FIGS. 1 and 2, the second power transmission means 42 provided in the base 41, the rotation drive means 43, and the lift drive means 44 will be described. .

  The base 41 is installed on the substrate 41a and the substrate 41a, and is erected on the frame body support portion 41b on which the frame body 11 of the above-described shaft rod lifting and rotating mechanism 19 is supported, and on the substrate 41a. It is comprised from the raising / lowering drive means support part 41c which supports the raising / lowering drive means 44 above the shaft rod raising / lowering rotation mechanism 19. FIG.

  The elevating drive means 44 includes a rotation drive device 44a installed on the upper portion of the elevating drive means support portion 41c, a disk 44c fixed to the front end portion of the rotation shaft 44b of the rotation drive device 44a, and the rotation shaft 44b of the disk 44c. A rod 44e having an upper end connected to a position different from the center position and a lower end connected to the lifting plate 44d and capable of tilting (rotating) around each of the ends; It is comprised from the two linear guides 44f which are equipped in the front surface of the support part 41c and which support the raising / lowering board 44d so that raising / lowering is possible.

  The rod connected to the disk 44c is operated by operating the rotation drive device 44a of the elevating drive means 44 and rotating the disk 44c fixed to the rotation shaft 44b of the rotation drive device 44a clockwise or counterclockwise. 44e moves up and down while tilting. Thereby, the raising / lowering board 44d connected to the lower end part of the rod 44e can be raised / lowered.

  In the component placement device 10, the lifting drive means 44 is placed in contact with the upper end portion of each shaft rod 12 of the shaft rod lifting and lowering rotation mechanism 19 via the shaft rod support 31 and the coupling rod 32, and the coupling rod 32 is moved up and down. The plate 44d is fixed to each other via bolts (FIG. 4:33). Accordingly, by operating the rotation driving device 44a of the lifting drive means 44, a total of six shaft rods 12 provided in the shaft rod lifting and rotating mechanism 19 can be lifted and lowered simultaneously.

  It should be noted that a known linear motion drive device, for example, a linear motion drive device composed of a rotation drive device and a feed screw, or a linear motor may be used in place of the lift drive means 44 described above.

  FIG. 6 is a perspective view illustrating a configuration of a portion in the vicinity of the frame body support portion 41b of the base 41 provided in the component placement device 10 illustrated in FIGS. 1 and 2.

  The frame support part 41 b is composed of a total of six support posts 45 erected on the substrate 41 a and a table plate 46 supported by these support posts 45.

  The table plate 46 is provided with a rotation drive means 43 connected to a second power transmission means 42 that is detachably engaged with a rotation transmission means (FIG. 5: 18) of the shaft rod up-and-down rotation mechanism.

  The second power transmission means 42 includes a total of eight pulleys 42b, 42c, 42d, 42e, 42f, and 42g that support the belt 42a and the belt 42a disposed below the table plate 46 on the table plate 46. 42h, 42k, arranged above the table plate 46, a pulley 42m mounted around the rotating shaft of the pulley 42b, and a pulley 42p connected to the pulley 42m via a belt 42n. . The pulley 42 p is attached to the rotation shaft of the rotation driving means 43.

  Accordingly, when the rotation driving means 43 is operated, the pulley 42p connected to the rotation driving means 43 via the pulley 42p, the belt 42n, and the pulley 42m is rotationally driven. The belt 42a supported by the pulley travels.

  On the other hand, linear guides 47 and 48 are installed on the upper surface of the table plate 46. The linear guide 47 includes a rail 47a and a slider 47b that can move along the rail 47a. Similarly, the linear guide 48 includes a rail 48a and a slider 48b that can move along the rail 48a.

  A pulley support member 51 is provided on the slider 47 b of the linear guide 47. A shaft bar 53 a is provided on the lower surface of the pulley support member 51. The shaft bar 53a passes through the long hole 46a of the table plate 46, and supports the pulley 42d rotatably at the lower end. Accordingly, the pulley 42d is movable along the rail 47a together with the slider 47b.

  Similarly, a pulley support member 52 is provided on the slider 48 b of the linear guide 48. A shaft bar 53 b is provided on the lower surface of the pulley support member 52. The shaft bar 53b passes through the long hole 46b of the table plate 46, and supports the pulley 42h rotatably at the lower end portion. Accordingly, the pulley 42h is movable along the rail 48a together with the slider 48b.

  Supports 54 a and 54 b are erected on the upper surface of the table plate 46. And the opening part 51a of the said pulley support member 51 and the support | pillar 54a are mutually connected via the tension coil spring (not shown). Similarly, the opening 52a of the pulley support member 52 and the column 54b are connected to each other via a tension coil spring (not shown).

  Therefore, as shown in FIG. 6 and FIG. 7, in the state where the frame body 11 of the above-described shaft rod lifting and lowering rotation mechanism 19 is not mounted on the frame body support 55 installed on the base 41 described later, the pulley 42d and 42h move to the support columns 54a and 54b, respectively, and apply an appropriate tension to the belt 42a so as not to break or loosen.

  Below the table plate 46, there is provided a frame body support 55 for detachably supporting the frame body 11 of the shaft bar lifting and lowering rotation mechanism 19.

  The frame body support 55 is provided on the front surface of the case 55a, the case 55a, and two projections 55b for positioning the frame body 11 when the frame body 11 of the above-described shaft rod lifting and rotating mechanism 19 is mounted. And the two hook-shaped arms 55c which hold | maintain the frame 11 temporarily are provided. Each of the two arms 55c is supported by an arm support 55d, and can swing about the base. Each arm 55c is applied with a driving force by a coil spring housed in the arm support 55d so that the tip of the arm 55c moves to the opposite arm side.

  A total of four movable pins 55e are provided on the front surface of the case 55a. Each movable pin 55e is given a driving force so as to move forward by a coil spring housed inside the case 55a.

  Next, a procedure for attaching and detaching the frame 11 of the shaft rod up-and-down rotation mechanism 19 to the base 41 will be described.

  First, when the frame body 11 of the shaft rod lifting and lowering rotation mechanism 19 shown in FIG. 3 is arranged on the front side of the frame body support tool 55 shown in FIG. 6 and the frame body 11 is pressed against the frame body support tool 55, the frame body 11 is inserted into the opening 11d formed in the column 11c, and the positioning projection 55b of the frame support 55 is inserted, thereby positioning the frame 11, and as shown in FIG. The tip of the hook-like arm 55c of the support 55 is engaged with the support 11c of the frame 11, and the frame 11 is temporarily fixed so as not to move forward. At this time, the four movable pins 55 e included in the frame body support tool 55 apply a driving force that moves the frame body 11 forward to the support pillar 11 c of the frame body 11. As a result, the front and rear of the support 11c of the frame 11 are closely supported by the arm 55c and the movable pin 55e of the frame support 55, so that the frame 11 can be prevented from finely moving in the front-rear direction.

  And as shown in FIG.1 and FIG.2, the connecting rod 32 which connects the shaft-bar support tool 31 which supports the upper end part of each shaft-rod 12 of the shaft-rod raising / lowering rotation mechanism 19 is attached to a volt | bolt (FIG. 4: 33) is fixed to the lifting plate 44d by connecting the shaft bar lifting / lowering rotating mechanism 19 to the lifting / lowering driving means 44.

  By such a simple operation, the frame 11 of the shaft rod lifting and lowering rotation mechanism 19 can be easily attached to the base 41 in a short time.

  On the contrary, the connecting rod 32 is removed from the lifting plate 44d of the lifting and lowering drive means 44, and then the tip of the arm 55c of the frame support 55 is moved to the opposite side of the opposing arm, thereby By disengaging the support 11c and the arm 55c of the body 11 and moving the frame 11 forward, the frame 11 of the shaft bar lifting and lowering rotation mechanism 19 can be easily and quickly removed from the base 41. Can be removed.

  In FIG. 8, the rotation transmission means 18 shown in FIG. 5 and the second power transmission means 42 shown in FIG. 7 are engaged with each other by mounting the frame 11 of the shaft bar lifting and lowering rotation mechanism 19 on the base. It is a figure shown in a state.

  As shown in FIG. 8, when the frame 11 of the shaft rod lifting / lowering mechanism 19 is attached to the base, the pulleys 18 a and 18 b of the rotation transmitting means 18 of the shaft rod lifting / lowering mechanism 19 are connected to the second power transmitting means 42. The belt 42a is pressed and engaged. Thereby, the first power transmission means 17 is engaged with the second power transmission means 42 (for example, via the rotation transmission means 18). At this time, the pulleys 42d and 42h of the second power transmission means 42 are respectively provided with arrows 56a and 56b shown in FIG. 8 so that an appropriate tension is applied so that the belt 42a is not broken or loosened. It moves in the direction shown (the direction opposite to the side of the columns 54a and 54b shown in FIG. 6).

  Accordingly, as shown in FIGS. 1 and 2, when the frame body 11 of the shaft rod lifting / lowering rotation mechanism 19 is mounted (supported) on the base 41 via the frame body support 55, each of the shaft rod lifting / lowering rotation mechanisms 19 is provided. The rotation driving means 43 can be immediately connected to the shaft rod lifting / lowering rotation means 16 via the first power transmission means 17, the rotation transmission means 18, and the second power transmission means 42.

  In this way, the component placement apparatus 10 is configured to attach (or remove from) the base body 41 of the frame body 11 of the shaft bar up-and-down rotation mechanism 19 and to rotate and drive the shaft bar up-and-down rotation means 16. Connection to 43 (or removal from the rotation drive means 43) can be performed very easily and in a short time.

  For this reason, for example, when a plurality of the shaft rod lifting / lowering mechanisms 19 are prepared in advance, the shaft rod 12 or the linear motion bearing of the shaft rod lifting / lowering mechanism 19 mounted on the component placement device 10 is replaced. By removing the frame 11 of the shaft rod lifting / lowering mechanism 19 from the base 41 and attaching another frame of the shaft rod lifting / lowering mechanism to the base 41, the shaft rod or the linear motion bearing can be made extremely simple and short. Can be exchanged in time.

  Further, the positional relationship (for example, adjacent shafts) of the linear motion bearing and the rotary bearing 15 (that is, the shaft rod lifting / lowering means) supporting each shaft rod 12 by the frame 11 of the shaft rod lifting / lowering mechanism 19 is provided. Since the distance between the rods is fixed in advance, it is not necessary to adjust the positional relationship every time the shaft rod or the linear motion bearing is replaced.

  1 and 2, the frame body 11 is supported on the base 41 using a frame body support tool 55 including two arms 55c. If it is not necessary to attach and detach the frame body 11 frequently, the frame body 11 can be fixed to the base 41 using, for example, a bolt.

  As shown in FIGS. 1 to 8, in the component placement device 10, the rotation transmission means 18 includes pulleys 18 a and 18 b installed on the frame body 11, and the second power transmission means 42 is installed on the base 41. And the pulleys 18a and 18b and the belt 42a are engaged with each other. In contrast, the rotation transmission means includes a belt installed on the frame, the second power transmission means includes a pulley installed on the base, and the pulley and the belt are engaged with each other. May be.

  FIG. 9 is a diagram schematically showing another configuration example of the rotation transmission unit and the second power transmission unit in a state in which both units are engaged with each other.

  As the rotation transmission means 98 shown in FIG. 9, gears 98a and 98b installed on the frame 11 are used, and as the second power transmission means 92, it is installed on the table plate 46 provided in the base. , Gears 92a and 92b mounted on the rotation shafts 93a and 93b of the rotation driving device are used. The configuration of the first power transmission means 17 shown in FIG. 9 is the same as the configuration of the first power transmission means shown in FIG.

  Then, by operating the rotary drive device and rotating the rotary shaft 93a, the rotary shaft 93a is rotated by the gear 92a of the second power transmission means 92, the gear 98a of the rotation transmission means 98, and the first power transmission means. A total of three shaft rods 12 supported by each of the linear motion bearings 14a, 14b, and 14c connected via 17 can be simultaneously rotated.

  Similarly, by operating the rotary drive device and rotating the rotary shaft 93b, the rotary shaft 93b is rotated by the gear 92b of the second power transmission means 92, the gear 98b of the rotation transmission means 98, and the first power transmission. In total, the three shaft rods 12 supported by each of the linear motion bearings 14d, 14e, and 14f connected via the means 17 can be rotated simultaneously.

  Thus, gears can be used as the rotation transmission means and the second power transmission means. A gear can be used as the first power transmission means.

  Further, for example, a combination of a rack and a pinion can be used as a combination of the rotation transmission unit and the second power transmission unit.

  As described above, the component placement device of the present invention has a configuration in which the frame of the shaft rod lifting and rotating mechanism is detachable from the base. When there is a change in the type of tray to be accommodated, the shaft bar lifting / lowering rotation mechanism mounted on the component placement device can be immediately replaced with another shaft rod lifting / lowering rotation mechanism prepared in advance. Excellent versatility.

  For example, the shaft rod lifting / lowering rotation mechanism mounted on the component placement device is housed in a shaft rod lifting / lowering rotation mechanism including a shaft rod having a suction nozzle suitable for holding a specific component at the lower end, or a specific tray. It can be exchanged for a shaft rod lifting / lowering rotation mechanism in which the interval between the shaft rods is set at an interval corresponding to the interval of the parts, or a shaft rod lifting / lowering rotation mechanism having a larger (or fewer) number of shaft rods.

  In the present specification, the component placement device of the present invention has been described by taking the device for placing six components at the same time as shown in FIGS. 1 and 2 as a representative example. As described above, when the shaft rod lifting / lowering rotation mechanism is replaced with another various types of shaft rod lifting / lowering rotation mechanisms, the lifting / lowering driving means is provided for each of the shaft rod lifting / lowering rotation mechanisms in order to further enhance the versatility of the component placement device. The shaft rod can be driven up and down independently (for example, using the same number of lifting drive means as the number of shaft rods, each shaft bar can be driven up and down independently by each lifting drive means), and rotational drive The means is configured such that each shaft rod of the shaft rod lifting and rotating mechanism can be independently driven to rotate (the number of rotation driving means is the same as the number of shaft rods, and each shaft rod is independently rotated by each rotation driving means. Is preferable).

The first power transmission means 17 and the second power transmission means 42 are mounted on the base 41 provided so as to engage with each other (for example, via the rotation transmission means 18). As a result, it can be assembled easily and in a short time.

  Further, for example, when the shaft rod 112 is bent and a malfunction occurs in the operation of the shaft rod lifting and rotating mechanism as shown in FIG. Displacement target component temporary holding device in which a failure has occurred) 19a is detached from the base 41, and then a separately assembled shaft rod lifting / lowering rotation mechanism (arrangement target component temporary holding device in which operation does not cause a failure) 19b is mounted on the base 41 such that the first power transmission means 17 and the second power transmission means 42 are engaged (for example, via the rotation transmission means 18) (the repair method of the present invention). Can be repaired easily and in a short time.

  Examples of malfunctions occurring in the shaft rod lifting / lowering mechanism include a decrease in accuracy of component placement due to curvature of the shaft rod and a decrease in accuracy of component placement due to uneven wear of the shaft rod.

  Furthermore, as shown in FIG. 12, the component placement apparatus 10 in FIG. 1 disengages the shaft bar lifting / lowering rotation mechanism (arrangement target component temporary holding device) 19 mounted on the component placement apparatus 19 from the base 41, then. Separately prepared shaft rod lifting and lowering rotation mechanism (arrangement target component temporary holding device) 19c is used as a base 41, and first power transmission means 17 and second power transmission means 42 (for example, rotation transmission). By mounting them so that they are engaged with each other (through the means 18) (by performing the replacement method of the temporary holding device for the component to be arranged according to the present invention), the shaft bar lifting and rotating mechanism can be replaced easily and quickly. can do.

  As shown in FIG. 12, the separately prepared shaft bar lifting / lowering rotation mechanism 19 c prepared separately is preferably the same as the shaft bar lifting / lowering rotation mechanism 19 detached from the base 41. Such an exchange method can be advantageously used, for example, when inspecting and maintaining the shaft bar lifting and rotating mechanism.

  Specifically, by replacing the shaft rod lifting / lowering rotation mechanism 19 mounted on the component placement device with a shaft rod lifting / lowering rotation mechanism 19c (having the same configuration as the shaft rod lifting / lowering rotation mechanism 19), For example, the filling amount of a lubricant (eg, grease) between the shaft rod and the linear motion bearing of the shaft rod lifting and lowering rotation mechanism 19 detached from the base 41 is checked, and lubrication is performed when the filling amount is insufficient. Even during the maintenance work (maintenance) for replenishing the agent, the work for placing the components using the shaft rod lifting and lowering rotation mechanism 19c can be continued.

  As a previously assembled shaft rod lifting / lowering rotation mechanism prepared for replacement, various configurations can be used. Next, an example will be described with reference to FIG.

The work of placing the parts can be started immediately.

  As shown in FIG. 15, the configuration of the first power transmission means 27 includes the number of shaft rods 12 (therefore, the number of linear motion bearings supporting the shaft rods and the number of rotary bearings supporting the linear motion bearings). ) Is different from that of the first power transmission means 17 shown in FIG.

  An example of a change in the function of the shaft rod lifting and rotating mechanism is to change the number and length of the shaft rods, and an example of a grade change is that the linear motion bearing or rotary bearing is made higher than the shaft rod. It is possible to change (upgrade) to one that can be moved up and down with precision.
