  FIG. 4 shows the component supply unit 5 installed on the right side, but the configuration of the component supply unit 5 is slightly different from that of FIG. Detailed description will be omitted.

  In the component supply apparatus 1, component supply units 5 are formed on the left and right sides of the housing 4, and a work area 6 is provided between the left and right component supply units 5. An electric screwdriver 3 as a tool is disposed above the left and right component supply units 5, and an assembly operator performs work by being positioned on the front side F of the component supply device 1. When the worker is located at the work position F, the switches 24 and 25 are turned on to send the bolt 2 from the component supply unit 5 to the parallel plate 16, and hold the electric screwdriver 3 to start the work.

  The chassis 7 and the electronic substrate 8 are carried into the work area 6 as members to be coupled. Further, the bolt 2 is transferred to the standby position P of the parallel plate 16 by the vibration device of the component supply unit 5. When the electronic board 8 is coupled to the chassis 7, the operator holds the electric screwdriver 3 with the left and right hands, and moves the tip of the electric screwdriver 3 toward the recess 18 </ b> A of the horizontal positioning plate 18 of the guide portion 15. Let At this time, the operator may not visually check the left and right guide portions 15.

  This is because the guide portions 15 are installed on the left and right sides in the direction in which both hands of the operator extend and reach, so that the tip of the electric screwdriver 3 is generally connected to the first edge 18E of the horizontal positioning plate 18. First, the front end portion of the electric screwdriver 3 comes into contact with the second edge portion 18F as the hand is extended forward. Since the intersection of the first edge 18E and the second edge 18F is determined as the standby position P of the bolt 2, if the electric driver 3 is moved downward as it is, the lower end of the electric driver 3 is set at the standby position. It hits the bolt 2 of P.

  When the operator pushes down the electric screwdriver 3, the motor of the electric screwdriver 3 starts to rotate, and the lower end portion of the electric screwdriver 3 is eventually engaged with the head of the bolt 2. As a result, the bolt 2 is supported by the electric driver 3. Since the magnet is attached to the lower end portion of the electric screwdriver 3, the iron bolt 2 is attracted to the electric screwdriver 3, and when the electric screwdriver 3 is lifted, the bolt 2 is lifted upward and taken out. The next bolt 2 is sent to the standby position P.

  After the bolt 2 is supported by the electric screwdriver 3, the electric screwdriver 3 is moved over the mounting hole 9 of the electronic board 8, and the electric screwdriver 3 is moved downward. The trained operator can insert the bolts 2 of the electric screwdriver 3 into the left and right mounting holes 9 almost simultaneously without carefully checking each time. When the electric screwdriver 3 is pressed against the work area 6 side, the tip of the electric screwdriver 3 The bolt 2 passing through the mounting hole 9 by rotating the part is fastened to the bolt hole of the chassis 7. The completion of the fastening of the bolt 2 is determined by detecting that the motor of the electric driver 3 stops rotating and the current of the motor coil increases. When the completion of the fastening of the bolt 2 is detected, the motor is stopped and the electric driver 3 is raised. Since the bolt 2 is fastened to the chassis 7, the bolt 2 incorporated from the lower end of the electric screwdriver 3 is released. The operator can continue the next bolting operation.

  As described above, the component supply apparatus 1 according to this embodiment includes the storage chamber 13 for the bolt 2 that joins the chassis 7 and the electronic substrate 8 that are members to be joined, and the bolt 2 is fed out to a predetermined standby position. Are provided with a passage 14 for waiting the bolt 2 in a predetermined posture and a guide portion 15 for guiding the electric screwdriver 3 for taking out and operating the bolt 2, and the guide portion 15 is located above the standby position P.

  As a result, when the electric screwdriver 3 is taken out by the electric screwdriver 3 to perform a coupling operation or the like, the electric screwdriver 3 is inserted into the recess 18A of the guide portion 15 from the substantially horizontal direction, and the electric screwdriver 3 The lower end can be located. Therefore, when the electric screwdriver 3 is moved downward, the lower end portion of the electric screwdriver 3 comes into contact with the bolt 2 and can be fitted in a short time. For this reason, the joining work of the chassis 5 and the electronic substrate 8 can be performed in a short time.

  In particular, since the recess 18A is formed in a substantially L shape, if the electric driver 3 hits either the first edge 18E or the second edge 18F inside the L shape, the electric driver 3 Can be easily guided to the corner of the recess 18A.

  In addition, the guide portion 15 is provided at a position where the operator can reach his / her hand ahead of the side portion, and the concave portion 18A of the guide portion 15 includes a first edge portion 18E extending in the front-rear direction on the side of the operator. The second edge portion 18F extending in the left-right direction is disposed so that the second edge portion 18F is positioned closer to the body center side of the worker than the first edge portion 18E. If the hand holding 3 is extended, the tool comes into contact with the first edge portion 18E of the concave portion of the guide portion. Therefore, when the electric screwdriver 3 is pushed forward, it is guided by the first edge 18E and hits the second edge 18F. Since the corner portions of the first edge portion 18E and the second edge portion 18F are determined as the standby position P of the bolt 2, the electric screwdriver 3 can be quickly positioned and the bolt 2 can be easily taken out.

  Further, since the storage chamber 13, the passage 14, and the guide portion 15 are installed at symmetrical positions around the worker's work area 6, the worker simultaneously operates the electric screwdriver 3 using both hands. be able to.

  Since the angle forming the substantially L-shape of the recess 18A is in the range of 45 ° to 90 °, when the electric driver 3 is brought into contact with the recess 18A, the electric driver 3 can slip out of the recess 18A. The work efficiency is improved.

  The vertical guide plate 19 that is the vertical positioning portion is formed with a notch-shaped or hole-shaped opening 23 that extends horizontally through the electric screwdriver 3, so that the electric screwdriver 3 is moved when the electric screwdriver 3 is moved downward. The bolt 2 can be taken out without visually checking the moving direction.

  Next, when the angle formed by the vertical guide plate 19 with the horizontal positioning portion is set within a range of 60 ° to 80 °, the electric driver 3 has less resistance when moving up and down, and the left and right deflections are not caused. Few. For this reason, even if it is inserted into the vertical guide plate 19 when the bolt 2 is taken out, the operator does not feel uneasy that the electric screwdriver 3 has been displaced, and the operator can continue working without causing any hesitation. it can. In particular, when the vertical guide plate 19 has a substantially frustum shape, the electric screwdriver 3 is accurately positioned on the bolt 2.

  In addition, the installation interval and the position in the front-rear direction of the component supply units 5 and 5 may be adjustable. By making it possible to adjust the installation interval of the component supply units 5 and 5 or the position in the front-rear direction, the work can be performed according to the physique of the operator.
