The assembly board holding frame 12 has an upper end portion 19T, an intermediate portion 19M, and a lower end portion 19C. The upper end portion 19T holds the upper end portion 13B of the assembly board 13, the intermediate portion 19M holds the intermediate portion 13C of the assembly board 13, and the lower end portion 19C holds the lower end portion 13D of the assembly board 13.

  The intermediate portion 19M of the assembly board holding frame 12 is held between the upper end portions 15D of the left and right columns 15 of the work table 11, and the intermediate portion 19M of the assembly board holding frame 12 is set to the upper ends of the left and right columns 15. The shaft 15 is supported so as to be rotatable along the R direction with respect to the portion 15D. That is, the intermediate portion 13 </ b> C of the assembly board 13 is supported to be rotatable along the R direction using the intermediate portion 19 </ b> M of the assembly board holding frame 12 and the support shaft 18.

Next, the rotation mechanism unit 50 will be described with reference to FIGS. 1 and 2.
The rotation mechanism unit 50 rotatably holds the assembly board holding frame 12 so that the upper end part 13B and the lower end part 13D of the assembly board 13 can advance and retreat toward the worker side. 15 can be held at an arbitrary angle so as to be rotatable about the support shaft 18.
2A and 2B show examples in which the assembly board 13 is held at an arbitrary angle with respect to the work table 11, and in FIG. 2, it is easy to see the rotation mechanism unit 50. Therefore, the illustration of the angle holding mechanism 80 and the component tray 41 shown in FIG. 1 is omitted.

The rotation mechanism unit 50 shown in FIGS. 1 and 2 is disposed on both the left and right side surfaces of the base 11, for example. Each rotation mechanism unit 50 has the same structure on the left and right, and includes an intermediate plate 21 and an air cylinder 22 that is an example of a drive operation unit.
The intermediate plates 21 are fixed to the left and right side surfaces of the assembly board holding frame 12, respectively. The upper end portion of the intermediate plate 21 is located on the support shaft 18, and the support shaft 18 is the rotation center of the intermediate plate 21. The lower end portion of the intermediate plate 21 reaches the lower end portion 13D of the assembly board 13.
The air cylinders 22 are respectively disposed on the left and right side surfaces of the assembly board holding frame 12. The tip of the rod 24 of each air cylinder 22 is attached so as to be able to rotate to a substantially intermediate position of the intermediate plate 21 via a joint 23. The mounting portion 25 of the air cylinder 22 is connected to the base portion 14 using a pin.

  FIG. 3 shows an example of the structure in the vicinity of the intermediate plate 21, the connecting pin 29, and the lower end portion 19 </ b> C of the assembly board holding frame 12, and the structures in the vicinity of the left and right are symmetrical. FIG. 3A shows a state in which the lever 99 is tilted when the connecting pin 29 protrudes. FIG. 3B shows a state where the lever 99 is raised when the connecting pin 29 is retracted. A connection pin 29 is attached to the inner surface side of the intermediate plate 21 using a member 28.

  As shown in FIG. 3B, the connecting pin 29 is moved forward and backward by operating the lever 99. As shown in FIG. 3A, when the pin 177 protrudes, the pin 177 is inserted into the center hole of the lower end portion 19C of the assembly board holding frame 12, and the rotation mechanism unit 50 and the assembly shown in FIG. The panel holding frame 12 is connected. As shown in FIG. 3B, when the pin 177 is retracted, the rotation mechanism 50 and the assembly board holding frame 12 are separated, and the assembly board holding frame 12 can be rotated 360 degrees.

  Further, the assembly board holding frame 12 shown in FIG. 1 can be mounted with two assembly boards 13 on the front and back, and the two assembly boards 13 can be switched and used. When the rear assembly board 13 is used, the upper end portion 19T of the assembly board holding frame 12 is disposed below, and a pin 177 is inserted into the center hole of the upper end portion 19T so that the rotation mechanism portion 50 and The assembly board holding frame 12 is connected.

Thereby, by supplying air to the air cylinder 22 shown in FIG. 2 and causing the rod 24 to extend, the upper end portion 13B (front end portion) of the assembly board 13 is moved in the R direction as shown in FIG. The assembly board 13 can be maintained in an inclined state by operating along the inclined position where the lower end portion 13C (rear end portion) is lowered.
As an example, in FIG. 2A, the assembly board 13 is held with a steep inclination at an angle θ1 with respect to the work table 11 and the installation surface F. In FIG. 2 (B), the assembly board 13 is held at a slant angle θ2 with respect to the work table 11. The angle θ1 is larger than the angle θ2.

  Returning to FIG. 1, the component tray 41 is disposed, for example, between the left and right angle holding mechanism portions 80 along the direction perpendicular to the paper surface of FIG. 1, and the component tray 41 passes through the left and right angle holding mechanism portions 80. The assembly board 13 and the assembly board holding frame 12 are held. The component tray 41 temporarily stores exterior components such as tubes and tapes used when assembling the wire harness.

Next, the angle holding mechanism 80 will be described with reference to FIGS. 1 and 5.
The angle holding mechanism 80 shown in FIG. 1 is used to always hold the component tray 41 at a predetermined angle with respect to the installation surface F of the wire harness assembling apparatus 10 when the assembly board 13 rotates in the R direction. .

  In the example of FIGS. 1 and 5, the angle holding mechanism portion 80 is disposed on each of the left and right side portions of the assembly board 13 and the assembly board holding frame 12, and includes a first link bar 31, a second link bar 32, The third link bar 33 and the link plate 34 are included. The first link bar 31 and the second link bar 32 are arranged in parallel, the upper end portion of the first link bar 31 is connected to the support shaft 18 as the center of rotation, and the lower end portion of the first link bar 31 is It is connected to the link plate 34 using pins 35.

The upper end portion of the second link bar 32 is connected to the pin 36 of the support column 15 as the center of rotation, and the lower end portion of the second link bar 32 is connected to the link plate 34 using the pin 37. The interval between the support shaft 18 and the pin 36 and the interval between the pins 35 and 37 are the same.
A straight line passing through the support shaft 18 and the pin 36 is parallel to the vertical direction Z. Similarly, the straight line through which the pins 35 and 37 pass is parallel to the vertical direction Z. The first link bar 31 and the second link bar 32 have the same length. The link plate 34 is a side portion of the component tray 41, and it is not necessary to prepare a plate separately from the component tray 41. Therefore, it is possible to prevent the number of components from increasing.

  The first link bar 31, the second link bar 32, and the link plate 34 are always attached so as to form a parallelogram. The link bar 33 connects the intermediate plate 21 and the link plate 34, and links the rotational movement of the assembly board 13 by the rotation mechanism unit 50 to operate the component tray 41.

  Thereby, even if the angle of the assembly board 13 and the assembly board holding frame 12 with respect to the installation surface F and the work table 11 changes, as illustrated in FIGS. 5 (A) and 5 (B), the component tray 41 is The angle holding mechanism 80 can be used to always hold a posture parallel to the installation surface F. Therefore, even if the angle of the assembly board 13 is changed, the component tray 41 is not hidden by the assembly board, and the component tray 41 is not tilted together with the assembly board 13. The parts are not spilled, and the operator cannot quickly and surely attach the exterior parts to the wires of the wire harness, thereby improving the wire harness assembly workability.

Next, the air supply part 100 is demonstrated with reference to FIG.1, FIG.4 and FIG.6.
FIG. 6 shows a connection example of the air supply source 200, the air supply port 51, and the plurality of wire harness assembling apparatuses 10.

  An air supply unit 100 shown in FIG. 1 supplies air to the left and right air cylinders 22 shown in FIG. The air supply port 51 of the air supply unit 100 shown in FIG. 1 is attached to the upper end portion of the column 15 of the work table 11, and air is supplied to the air supply port 51 from the air supply source 200 as shown in FIG. 6. It comes to supply. For example, by operating the operation handle 52 in one direction, air is supplied to the ports of the left and right air cylinders 22 so that the rod 24 of the air cylinders 22 is extended. Further, by operating the operation handle 52 in the other direction, air is supplied to the other ports of the left and right air cylinders 22 so that the rod 24 of the air cylinders 22 is contracted.

  As shown in FIG. 6, the air supply port 51 is connected to the air pipe 53 via a check valve 55, and when air is supplied from the air supply source 200 through the air supply port 51, the left and right air cylinders 22. , 22 is also supplied to the air pipe 53, and air can be supplied to the left and right air cylinders 22, 22 of all the wire harness assembling apparatuses 10 connected to the conveyor. The air pipe 53 is disposed along the conveyor CV, and the conveyor CV moves the plurality of wire harness assembly apparatuses 10 in an endless manner along the G direction.

Next, the assembly method of the wire harness using the wire harness assembly apparatus 10 mentioned above is demonstrated.
An operator who assembles the wire harness is disposed on the near side facing the lower end portion 13D of the assembly board 13 shown in FIG.

  First, as the wiring process, as shown in FIG. 5A, the assembly board 13 is raised, the upper end part 13B of the assembly board 13 is raised and the lower end part 13D is lowered, and the wire holding jig is formed from above the assembly board 13. Wire the wires to 17. When wiring the electric wire of the electric wire holding jig 17 below the assembly board 13, the operation handle 52 of FIG. 1 is raised and the rod 24 of the air cylinder 22 is moved forward, so that it is shown in FIG. Thus, the assembly board 13 is laid down, the upper end part 13B of the assembly board 13 is lowered, and the lower end part 13D is raised. The reason why the assembly board 13 is inclined at an arbitrary angle in this way is to make the lower end portion 13D of the assembly board 13 easy to work.

  Next, as a finishing process, exterior parts, such as a tape, a corrugated tube, a protector, and a clamp, are attached to the wire harness as exterior parts, and a required form is prepared. Even in this finishing process, the assembly board 13 is operated while being inclined at an angle at which it is easy to work.

  In the first embodiment of the present invention described above, by changing the angle of the assembly board 13, the operator can work on the assembly board 13 of any size without load. That is, even when using an assembly board 13 having a large size, for example, an operator can change the angle of the assembly board 13 to install the wiring of the electric wire and the exterior parts on the upper end portion 13B side of the assembly board 13. Easily without changing the posture of the person. By changing the angle of the assembly board 13, it is not necessary to attach the wiring of the electric wire and the exterior parts on the lower end portion 13 </ b> D side of the assembly board 13 in a posture in which the operator is bent, and the work can be easily performed. The worker does not need to stretch or lean forward, and can assemble the wire harness at an angle that is easy to work according to the height of the worker.

  Moreover, the component tray 41 can always hold a posture parallel to the installation surface F using the angle holding mechanism 80. Even if the angle of the assembly board 13 is changed, the component tray 41 is not hidden by the assembly board, and the component tray 41 is not inclined together with the assembly board 13. I won't spill. Therefore, the operator cannot quickly and surely attach the exterior part to the wire of the wire harness, and the wire harness assembling workability is improved.

Next, a second preferred embodiment of the wire harness assembling apparatus of the present invention will be described with reference to FIG.
The wire harness assembling apparatus 10 shown in FIG. 7 is substantially the same as the wire harness assembling apparatus 10 shown in FIG. Therefore, in the wire harness assembling apparatus 10 shown in FIG. 7, elements that are substantially the same as the corresponding elements of the wire harness assembling apparatus 10 shown in FIG. To do.

  The wire harness assembling apparatus 10 shown in FIG. 7 is different in that an electric cylinder 122 is newly used as a drive operation unit instead of the air cylinder 22 as a drive operation unit of the rotation mechanism unit 50 shown in FIG. is there. For this reason, the air supply port 51 and the operation handle 52 shown in FIG. 1 are omitted.

  The distal end portion of the rod 124 of the electric cylinder 122 is attached to a substantially intermediate position of the intermediate plate 21 via the joint 23. The attachment portion 125 of the electric cylinder 122 is connected to the base portion 14. In this example, the rotating machine rear portion 150 is constituted by the electric cylinder 122 and the intermediate plate 21.

  Thus, instead of supplying air, by changing the angle of the assembly board 13 by supplying driving power from the control unit 300 to the electric cylinder 122, the operator can work on the assembly board 13 of any size without any load. can do. That is, even when using an assembly board 13 having a large size, for example, an operator can change the angle of the assembly board 13 to install the wiring of the electric wire and the exterior parts on the upper end portion 13B side of the assembly board 13. Easily without changing the posture of the person. By changing the angle of the assembly board 13, it is not necessary to attach the wiring of the electric wire and the exterior parts on the lower end portion 13 </ b> D side of the assembly board 13 in a posture in which the operator is bent, and the work can be easily performed. The worker does not need to stretch or lean forward, and can assemble the wire harness at an angle that is easy to work according to the height of the worker.

  Moreover, the component tray 41 can always hold a posture parallel to the installation surface F using the angle holding mechanism 80. Even if the angle of the assembly board 13 is changed, the component tray 41 is not hidden by the assembly board, and the component tray 41 is not inclined together with the assembly board 13. I won't spill. Therefore, the operator cannot quickly and surely attach the exterior part to the wire of the wire harness, and the wire harness assembling workability is improved.

(Third embodiment)
Next, a preferred third embodiment of the wire harness assembling apparatus of the present invention will be described with reference to FIG.
The wire harness assembling apparatus 10 shown in FIG. 8 is substantially the same as the wire harness assembling apparatus 10 shown in FIG. For this reason, in the wire harness assembly apparatus 10 shown in FIG. 8, about the element which is substantially the same as the corresponding element of the wire harness assembly apparatus 10 shown in FIG. To do.

The wire harness assembling apparatus 10 shown in FIG. 8 is different in that a drive operation unit 190 is used instead of the air cylinder 22 as the drive operation unit of the rotation mechanism unit 50 shown in FIG. For this reason, the air supply port 51 and the operation handle 52 shown in FIG. 1 are omitted. The drive operation unit 190 includes a motor 73, a gear 71 rotated by the motor 73, and a toothed plate 72 fixed to the assembly board 13 and meshing with the gear 71.
The motor 73 is fixed to the base 14, and a gear 71 is attached to the output shaft of the motor 73. The toothed plate 72 is substantially fan-shaped, and the tooth portion 74 of the toothed plate 72 is engaged with the gear 71. The upper end of the toothed plate 72 is fixed to the assembly board holding frame 12.

  As a result, the controller 350 drives the motor 73 to change the angle of the assembly board 13 so that the operator can work without any load on the assembly board 13 of any size. That is, even when using an assembly board 13 having a large size, for example, an operator can change the angle of the assembly board 13 to install the wiring of the electric wire and the exterior parts on the upper end portion 13B side of the assembly board 13. Easily without changing the posture of the person. By changing the angle of the assembly board 13, it is not necessary to attach the wiring of the electric wire and the exterior parts on the lower end portion 13 </ b> D side of the assembly board 13 in a posture in which the operator is bent, and the work can be easily performed. The worker does not need to stretch or lean forward, and can assemble the wire harness at an angle that is easy to work according to the height of the worker.

  Moreover, the component tray 41 can always hold a posture parallel to the installation surface F using the angle holding mechanism 80. Even if the angle of the assembly board 13 is changed, the component tray 41 is not hidden by the assembly board, and the component tray 41 is not inclined together with the assembly board 13. I won't spill. Therefore, the operator cannot quickly and surely attach the exterior part to the wire of the wire harness, and the wire harness assembling workability is improved.

(Fourth embodiment)
Next, a fourth preferred embodiment of the wire harness assembling apparatus of the present invention will be described with reference to FIG.
In the wire harness assembling apparatus 10 of each embodiment shown in FIGS. 1 to 8, the work table 11 is connected to a conveyor. However, the wire harness assembling apparatus 10 shown in FIG. 9 is substantially the same as the wire harness assembling apparatus 10 shown in FIG. For this reason, in the wire harness assembly apparatus 10 shown in FIG. 9, about the element which is substantially the same as the corresponding element of the wire harness assembly apparatus 10 shown in FIG. To do.

  The wire harness assembling apparatus 10 shown in FIG. 9 is different in that the fixing member 116 is used without using the four wheels 16 shown in FIG. Thereby, the workbench 11 can be fixed to the installation surface F, and the workbench 11 is fixed, and the wire harness is assembled in the assembly board 13.

  Thus, in the fourth embodiment of the present invention, as in the first embodiment, by changing the angle of the assembly board 13, the operator can work on the assembly board 13 of any size without load. That is, even when using an assembly board 13 having a large size, for example, an operator can change the angle of the assembly board 13 to install the wiring of the electric wire and the exterior parts on the upper end portion 13B side of the assembly board 13. Easily without changing the posture of the person. By changing the angle of the assembly board 13, it is not necessary to attach the wiring of the electric wire and the exterior parts on the lower end portion 13 </ b> D side of the assembly board 13 in a posture in which the operator is bent, and the work can be easily performed. The worker does not need to stretch or lean forward, and can assemble the wire harness at an angle that is easy to work according to the height of the worker.

  Moreover, the component tray 41 can always hold a posture parallel to the installation surface F using the angle holding mechanism 80. Even if the angle of the assembly board 13 is changed, the component tray 41 is not hidden by the assembly board, and the component tray 41 is not inclined together with the assembly board 13. I won't spill. Therefore, the operator cannot quickly and surely attach the exterior part to the wire of the wire harness, and the wire harness assembling workability is improved.

  The wire harness assembling apparatus 10 of the embodiment of the present invention includes an assembly board 13 for assembling a wire harness and a component tray 41 for temporarily placing components used for assembling the wire harness. The wire harness assembling apparatus 10 includes a rotating mechanism 50 that holds the upper end 13B and the lower end 13D of the assembly board 13 so that the upper end 13B and the lower end 13D can move forward and backward toward the operator, and a component tray when the assembly board 13 rotates. An angle holding mechanism unit 80 that holds 41 at a predetermined angle with respect to the installation surface F is provided.

  Thereby, in the wire harness assembly apparatus 10 of this invention, the wire harness assembly operation | work with the assembly board 13 of various sizes can be performed by changing the angle of the assembly board 13. FIG. Therefore, the back stretching work and the forward bending work do not occur, and the wire harness assembling work can be performed at an easy angle according to the height of the worker.

  In addition, even if the angle of the assembly board 13 is changed, the component tray 41 is always held at a predetermined angle with respect to the installation surface F. Does not fall. For this reason, components can be taken out from the component tray 41 and the assembly work of a wire harness can be performed easily and reliably. In addition, if the work is carried out at an angle that is easy to work according to the height of the worker, it is easy to take out the parts from the parts tray, so that the assembly workability of the wire harness is improved.

  The wire harness assembling apparatus 10 of the present invention includes an assembly board holding frame 12 that holds and fixes the assembly board 13. The rotation mechanism unit 50 rotatably holds the assembly board holding frame 12 with the support shaft 18 provided at the center of the assembly board holding frame 12 as the center of rotation. As a result, the assembly board 13 can be easily rotated while maintaining balance using the support shaft 18 at the center position of the assembly holding frame 12. The driving force for rotating the assembly board 13 can be small.

  The wire harness assembling apparatus 10 includes a work table 11 that supports an assembly board holding frame 12. The rotation mechanism unit 50 holds the assembly board holding frame 12 so as to be rotatable with respect to the work table 11 with the support shaft 18 as a center of rotation. A drive operation unit 22 that rotates the spindle 11 about the support shaft 18 is provided. Thereby, the assembly board holding frame 12 can be easily rotated around the support shaft 18 with respect to the work table 11 by the driving force of the driving operation unit 22.

  The angle holding mechanism 80 of the wire harness assembling apparatus 10 is a parallelogram link mechanism that is disposed between the assembly board holding frame 12 and the component tray 41. As a result, the component tray 41 can always be held in a fixed posture with respect to the installation surface F while adopting a simple mechanism, so that even if the assembly board 13 is rotated, exterior components will spill out of the component tray 41. There is no.

  The angle holding mechanism 80 of the wire harness assembling apparatus 10 includes a first link member 31 and a second link member 32. The upper end portion of the first link member 31 is connected to the support shaft 18 of the assembly board holding frame 12, and the lower end portion is connected to the component tray 41. The upper end portion of the second link member 32 is connected to the work table 11 side, and the lower end portion is connected to the component tray 41. The first link member 31 and the second link member 32 are parallel, the interval between the upper end portion of the first link member 31 and the upper end portion of the second link member 32, the lower end portion of the first link member 31, and the second link. The distance from the lower end of the member 32 is the same. As a result, a relatively compact parallelogram type link mechanism is employed, and the component tray 41 can always be held in a fixed posture with respect to the installation surface F. Therefore, even if the assembly board 13 is rotated, the component tray No exterior parts spill from inside 41.

Since the drive operation unit 22 of the wire harness assembly apparatus 10 is an air cylinder or an electric cylinder, the angle of the assembly board 13 can be changed smoothly and quickly.
