Description

Component placement apparatus and assembly method thereof

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

Conventionally, an electronic component mounting apparatus has been used to place and mount an electronic component at a predetermined position on the surface of a printed wiring board. An electronic component mounting apparatus usually has a shaft rod connected to a mechanism (for example, a decompression device or electromagnetic attachment / detachment means) that temporarily holds a component to be arranged, a shaft rod lifting / lowering drive means, and a shaft rod A component placement device including a rotation driving means is incorporated.

When mounting an electronic component, the electronic component mounting apparatus first moves the component placement apparatus above the tray in which the electronic component is accommodated. The component placement device lowers the shaft rod, operates the decompression device to attract and hold the electronic component on the lower end portion of the shaft rod, and then raises the shaft rod. Next, the electronic component mounting apparatus moves the component placement apparatus above a separately prepared printed wiring board. Electrical wiring is provided on the surface of the printed wiring board. The component placement device rotates the shaft bar to change the orientation of the electronic component so that electrical connection with the electrical wiring is possible. Next, the component placement device lowers the shaft rod and places the electronic component held at the lower end of the shaft rod at a predetermined position on the surface of the printed wiring board. Thereafter, the component placement device raises the shaft rod and returns it to the original position. By repeating such operations using an electronic component mounting apparatus, a large number of electronic components are mounted on the surface of the printed wiring board.

¡To enable rotation of the shaft rod, the shaft rod is housed and held in a cylindrical linear motion bearing. For example, a rotary drive device is connected to the shaft rod via power transmission means such as a belt mounted around the linear motion bearing.

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, 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. For this reason, there arises a problem that the support of the shaft rod by the linear motion bearing becomes unstable. In such a case, 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 failed due to wear with another normal shaft rod such as a new shaft rod.

However, in the conventional component placement device, the linear motion bearing that supports the shaft rod is connected to the rotary drive device via a power transmission means such as a belt, for example. Therefore, when exchanging the shaft rod, first, after removing the belt connecting the linear motion bearing and the rotary drive device, the shaft rod and the linear motion bearing are removed. Next, after attaching a linear motion bearing that supports another normal shaft rod, the linear motion bearing and the rotational drive device are stretched again to connect the belts to each other. Thus, since the operation | work which removes | removes a belt (power transmission means) when replacing | exchanging a shaft rod is complicated and requires time, the operation rate of an electronic component mounting apparatus is reduced.

For this reason, for example, when one of a plurality of shaft rods provided in the component placement device is bent and broken due to a collision with a surrounding mechanical device or the like, 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.

The component placement device of the present invention will be described with reference to the accompanying drawings showing its typical configuration. FIG. 1 is a perspective view showing a configuration example of a component placement device of the present invention. FIG. 2 is a side view of the component placement device 10 of FIG.

The component placement apparatus 10 according to the present invention includes a frame 11, a temporary holding means for a placement target component that is mounted on the frame 11 via a rotation means, and a first power transmission means 17 connected to the rotation means. And a base 41 that includes a second power transmission means 42 engaged with the first power transmission means 17 and detachably supports the frame 11. Etc.

The temporary holding means for the placement target part enables the temporary holding of the placement target part. For example, in the case of the illustrated component placement device 10, the placement target component temporary holding means corresponds to the shaft 12 connected to a mechanism (for example, a decompression device) that temporarily holds the placement target component.

Rotating means makes it possible to rotate and move the temporary holding means of the arrangement target part while holding the arrangement target part temporarily. For example, in the case of the illustrated component arrangement device 10, the rotation means is a linear motion bearing (eg, linear motion bearing 14 a) that supports the shaft rod so as to be movable up and down, and the linear motion bearing is supported so as to be rotatable together with the shaft rod 12. This corresponds to the rotating bearing 15.

The arrangement target component temporary holding device includes a frame, a temporary holding unit of the arrangement target component mounted on the frame via a rotation unit, and a first power transmission unit. For example, in the case of the illustrated component placement device 10, the placement target component temporary holding device is 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. The shaft rod 12 and the shaft rod elevating / rotating mechanism 19 provided with the first power transmission means 17 correspond to the shaft rod 12 and the first power transmission means 17.

In the component placement device of the present invention, the base may further include lifting drive means for temporarily holding the placement target parts. The raising / lowering drive means raises / lowers the temporary holding means of the component to be arranged. For example, in the case of the illustrated component placement apparatus 10, the elevation drive means corresponds to the elevation drive means 44 that raises and lowers the shaft rod 12.

In the component placement device of the present invention, means for driving and controlling the raising and lowering of the temporary holding means for the placement target parts may be further provided on the base instead of the above-described raising and 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, a means for driving the shaft rod upward (eg, an elastic body such as a spring) and a top portion of this shaft rod are pressed downward. Thus, a combination of means for controlling the vertical position of the shaft rod can be used.

Hereinafter, the configuration of the component placement apparatus 10 of FIGS. 1 and 2 which is a preferred embodiment of the component placement apparatus of the present invention will be described 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 elevating / rotating mechanism 19 including rotation transmitting means 18 supported by the frame 11 and connected to each of the shaft bar elevating / rotating means 16 via the first power transmitting means 17, And the rotation drive means 43 connected to the 2nd power transmission means 42 detachably engaged with the rotation transmission means 18 of the shaft rod raising / lowering rotation mechanism 19 and the upper end of the shaft rod 12 of the shaft rod raising / lowering rotation mechanism 19 Elevating drive means 44 arranged in contact with the part Includes a base 41, it has a configuration in which the frame body 11 of the axle lifting rotation mechanism 19 is detachably supported on the base 41.

The component placement device 10 is used, for example, by incorporating six components housed in a tray into a device that places (accommodates) them in a different tray.

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

FIG. 3 is a perspective view of the shaft rod up-and-down rotation mechanism 19 shown in 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 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, the components can be arranged efficiently, but the configuration of the shaft rod lifting / lowering mechanism 19 becomes complicated. Accordingly, the number of the shaft rod lifting / lowering rotation 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 rotating means 16 extends in the vertical direction. A part to be arranged is temporarily held at the lower end of the shaft rod 12. The shaft 12 is connected to a mechanism (not shown) that temporarily holds the component to be arranged.

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

The shaft rod 12 of the shaft rod lifting / lowering rotation mechanism 19 is hollow. 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. By actuating the pressure reducing device, it is possible to attract (temporarily hold) the component to be arranged to 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 the 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 rod 12 so as to be movable up and down.

A plurality of (for example, four) grooves 12a are formed on the outer circumferential surface of the shaft rod 12 at intervals in the circumferential direction. A plurality of grooves 13 a facing the grooves 12 a of the shaft rod 12 are formed on the inner peripheral surface of the cylindrical body 13. 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. Each rolling element 21 is engaged with the groove 12a and the groove 13a. For this reason, the shaft 12 does not rotate in the circumferential direction with respect to the cylinder 13.

As the linear motion bearing 14a, a known linear motion bearing including a cylindrical body that accommodates and supports the shaft rod so as not to rotate in the circumferential direction can be used.

The configuration of the

linear motion bearings

14b, 14c, 14d, 14e, and 14f is the same as the configuration 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.

As described above, the shaft 12 does not rotate in the circumferential direction with respect to the cylindrical body 13 of the linear motion bearing 14a. For this reason, the shaft 12 can be rotated in the circumferential direction together with the cylinder 13 by rotating the cylinder 13 of the linear motion bearing 14 a supported by the rotary bearing 15 in the circumferential direction.

Rotation transmitting means 18 is supported on the frame 11 of the shaft rod up-and-down rotation mechanism 19. The rotation transmission means 18 is connected to each of the above-described shaft rod up-and-down rotation means 16 via the first power transmission means 17.

The rotation transmission means 18 is composed of 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 engaged with a pulley 17e mounted around the cylindrical body 13 of each of the

linear motion bearings

14a and 14b. The belt 17b is engaged with a pulley 17e mounted around the cylindrical body 13 of each of the

linear motion bearings

14b and 14c. The belt 17c is engaged with a pulley 17e mounted around the cylindrical body 13 of each of the

linear motion bearings

14d and 14e. The belt 17d is engaged with a pulley 17e mounted around the cylindrical body 13 of each of the

linear motion bearings

14e and 14f.

Therefore, by rotating the pulley 18a, a total of three shaft rods 12 supported by the

linear motion bearings

14a, 14b, 14c connected to the pulley 18a via the

belts

17a, 17b can be simultaneously rotated. it can.

Similarly, by rotating the pulley 18b, the three shaft rods 12 in total supported by the

linear motion bearings

14d, 14e, 14f connected to the pulley 18b via the

belts

17c, 17d are simultaneously rotated. be able to.

3 and 4, each shaft rod 12 is supported by a shaft rod support 31. The shaft bar support 31 is 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, A connecting member 31d provided at the upper part of the cylindrical body 31c, a case 31e installed at the upper part of the connecting member 31d, a sphere 31g having a screw shaft 31f at the top and housed in the case 31e, and arranged above and below the sphere 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. For this reason, 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 supporting the shaft rod is likely to be unevenly worn. Therefore, it is necessary to replace the shaft rod or 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 be slightly rotated inside the case 31e. It can also move slightly in the radial direction of the annular body 31h together with 31h. For this reason, the upper end portion of the shaft rod 12 is not firmly fixed to the connecting rod 32. Therefore, the curve of the shaft rod 12 as described above can be suppressed. For this reason, 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 less likely to be unevenly worn. Accordingly, the frequency of replacing the shaft rod or the linear motion bearing is reduced.

Further, an annular packing 31k is provided between the cylindrical body 31a and the cylindrical body 31c. The packing 31k operates the pressure reducing device connected to the gas passage 31m to depressurize 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 described above The outside air is prevented from flowing into the gas passage 31m from between 31a and 31c.

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 arrangement device 10, the elevating drive means 44 is arranged (for example, contact arrangement) on the upper end portion of each shaft rod 12 of the shaft rod elevating and rotating mechanism 19 via the shaft rod support 31 and the coupling rod 32. The connecting rod 32 and the lifting plate 44d are 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.

In addition, it replaces with said raising / lowering drive means 44, A well-known linear motion drive device, for example, the linear motion drive device comprised from a rotational drive device and a feed screw, or a linear motor can also be used.

The pulley 42 p is attached to the rotation shaft of the rotation driving means 43.

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, so that the total of eight pulleys including the pulley 42b is obtained. The supported belt 42a 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 53 a passes through the long hole 46 a of the table plate 46. The pulley 42d is rotatably supported at the lower end of the shaft bar 53a. Accordingly, the pulley 42d is movable along the rail 47a together with the slider 47b.

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

Supporters 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 support 55 that detachably supports the frame 11 of the above-described shaft rod lifting and rotating 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 rotating mechanism 19 to the base 41 will be described.

First, the frame 11 of the shaft rod lifting and lowering rotation mechanism 19 shown in FIG. 3 is arranged on the front side of the frame support 55 shown in FIG. 6 and the frame 11 is pressed against the frame support 55. Thereby, the positioning projection 55b of the frame support 55 is inserted into the opening 11d formed in the column 11c of the frame 11, and the frame 11 is positioned. Subsequently, as shown in FIG. 1, the distal end portion of the bowl-shaped arm 55 c of the frame body support tool 55 engages with the column 11 c of the frame body 11 to temporarily fix the frame body 11 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. Thereby, the front and back of the support 11c of the frame 11 are closely supported by the arm 55c of the frame support 55 and the movable pin 55e. For this reason, the fine movement to the front-back direction of the frame 11 is prevented.

Next, as shown in FIGS. 1 and 2, the connecting rod 32 connecting the shaft rod support 31 of the shaft rod lifting and lowering rotation mechanism 19 is fixed to the lifting plate 44d using bolts (FIG. 4: 33). To do. As a result, the shaft rod lifting / lowering mechanism 19 is connected to the lifting / lowering driving means 44.

In this way, the frame 11 of the shaft bar lifting and lowering rotation mechanism 19 can be easily attached to the base 41 in a short time.

When removing the frame 11 from the base 41, first, the connecting rod 32 is removed from the elevating plate 44d of the elevating drive means 44. Next, the engagement between the support 11c of the frame 11 and the arm 55c is released by moving the tip of the arm 55c of the frame support 55 to the opposite side of the opposing arm. Then, the frame body 11 is moved forward. In this way, the frame 11 of the shaft rod lifting / lowering rotation mechanism 19 can be easily detached from the base 41 in a short time.

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, when a shaft rod lifting / lowering rotation mechanism different from the shaft rod lifting / lowering rotation mechanism 19 mounted on the component placement device 10 is prepared in advance, the frame 11 of the shaft rod lifting / lowering rotation mechanism 19 is removed from the base 41. By removing and attaching the frame body of the other shaft bar lifting and rotating mechanism to the base 41, the shaft bar or the linear motion bearing can be replaced very easily and in a short time.

Further, a mutual positional relationship (for example, an interval between adjacent shaft rods) of the linear motion bearing and the rotary bearing 15 (that is, the shaft rod lifting and rotating means) supporting each shaft rod 12 by the frame 11 is previously set. Since it is fixed, it is not necessary to adjust the positional relationship every time the shaft rod or the linear motion bearing is replaced.

In addition, in the component arrangement | positioning apparatus 10 shown in FIG.1 and FIG.2, the frame 11 is supported by the base 41 using the frame support tool 55 provided with the 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.

Also, as shown in FIGS. 1 to 8, in the component placement device 10, the rotation transmission means 18 includes

pulleys

18a and 18b installed on the frame 11, and the second power transmission means 42 is installed on the base 41. And the

pulleys

gearwheels

92a and 92b with which the

rotating shafts

93a and 93b of the rotation drive device were each mounted 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 linear motion bearing 14a connected to the rotary shaft 93a via the gear 92a, the gear 98a, and the first power transmission means 17, A total of three shaft rods 12 supported by 14b and 14c can be rotated simultaneously.

Similarly, the linear drive bearing 14d connected to the rotating shaft 93b via the gear 92b, the gear 98b, and the first power transmission means 17 by operating the above-described rotation driving device and rotating the rotating shaft 93b. , 14e, 14f, a total of three shaft rods 12 can be simultaneously rotated.

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

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

As described above, the component placement device according to the present invention is, for example, a shaft rod lifting / lowering rotation mechanism that is mounted on the component placement device when the type of component to be placed or the type of tray that houses the component is changed. Can be immediately replaced with a shaft rod lifting and rotating mechanism having a different configuration prepared in advance, so that it is excellent in 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 simultaneously placing six components shown in FIGS. 1 and 2 as a representative example. In order to further increase the versatility of the component placement device, the lifting drive means is configured to be able to drive the shaft rods of the shaft bar lifting and rotating mechanism independently, for example, as many lifting drive means as the number of shaft rods. It is also possible to provide a configuration in which each shaft rod can be driven up and down independently by each lifting drive means. Similarly, the rotation drive means is configured to be capable of independently rotating and driving each shaft rod of the shaft rod lifting and rotating mechanism. For example, the same number of rotation drive means as the number of shaft rods is provided, and each shaft rod is driven to rotate. It can also be set as the structure which can be rotationally driven independently by a means.

The component placement device of the present invention is used to place various components represented by electronic components (particularly, electronic components incorporated in various electronic devices), mechanical components, and optical components.

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 so that the first power transmission means 17 and the second power transmission means 42 are engaged with each other (for example, via the rotation transmission means 18). By performing the repair method of the placement device, the repair can be performed easily and in a short time.

Examples of malfunctions occurring in the shaft rod lifting / lowering mechanism include a decrease in accuracy in placing components due to the curvature of the shaft rod, and a decrease in accuracy in placing components 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 the components so as to be engaged with each other (through the means 18), that is, by implementing the method of replacing the component temporary holding device of the component arranging device of the present invention, It can be exchanged in a short time.

As shown in FIG. 12, the separately prepared shaft bar lifting / lowering rotation mechanism 19c prepared separately has the same configuration 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 performing the above replacement method, for example, filling of a lubricant (eg, grease) between the shaft rod of the shaft rod lifting and lowering rotation mechanism 19 detached from the base 41 and the linear motion bearing The shaft rod up-and-down rotating mechanism 19c attached to the base 41 is used during the maintenance management (maintenance) operation of checking the amount and replenishing the lubricant when the filling amount is insufficient. Thus, the work of arranging the parts can be continued.

As the shaft bar lifting / lowering rotation mechanism prepared separately, those of various configurations can be used. Next, an example will be described with reference to FIG.

As shown in FIG. 13, the separately prepared shaft rod lifting / lowering mechanism 19d prepared in advance has a different configuration from the shaft rod lifting / lowering mechanism 19 detached from the base 41, but is compatible. May be. Such an exchange method can be advantageously used, for example, when changing the function or grade of the shaft rod lifting and rotating mechanism.

The shaft bar lifting / lowering rotation mechanism 19 separated from the base 41 has a configuration including six shaft bars in total. On the other hand, the shaft rod lifting and lowering rotation mechanism 19d prepared separately has a configuration including a total of four shaft rods. As described above, the shaft rod elevating / rotating mechanism 19d has a configuration different from that of the shaft rod elevating / rotating mechanism 19, but is compatible. “Compatible” means that the shaft rod lifting / lowering mechanism 19d can be mounted on the base 41 from which the shaft rod lifting / lowering mechanism 19 is removed.
