The operation of this embodiment will be explained.

In an electronic component automatic mounting machine, the mechanical unit 1 needs to be replaced when (1) the remaining number of chip-shaped electronic components 30 is not the number required for production, and (2) when the production model is changed. There are two main ways to change the arrangement of the mechanical unit 1 on the stand 3. One is to instruct the control unit 9 about the replacement timing and contents from the control unit (not shown) of the automatic electronic component mounting machine. It has become.

The control device 9 operates the embodiment device as follows in response to instructions from the control section.

According to instructions from the control device 9, the movable rod 6 moves to a predetermined position along the upper and lower rods 5a and 5b of the device base 5, while the support base 8 attached to the movable rod 6 moves. It moves vertically along the rod 6 and is fixed at a predetermined height position. That is, the transport head 7 moves in the horizontal and vertical directions (X-Y directions in the drawing). At the same time, the rotation axis of the transfer head 7 is rotated to place the transfer head 7 above the installation stand 3 of the mechanical unit 1 (indicated by θ in the figure), and the transfer head 7
The chuck 13 and fingers 11 move onto the actuator 37 and drive it so that the mechanism unit 1 on the installation stand 3 can be chucked from above.
And the finger 11 rotates (indicated by θ1 in the figure).

When the position is set by the above operation, the tip of the transfer head 7 such as the chuck 13 and fingers 11 is moved to the cylinder 1.
6 extends toward the electronic component automatic mounting machine side, that is, toward the installation stand 3 side, and the fingers 11 grip the mechanical unit 1 by driving the chuck 13.

Thereafter, the tip of the transport head 7 is shortened again by the cylinder 16, and this operation causes the mechanical unit 1 to move away from the installation base 3, and the transport head 7, while gripping the mechanical unit 1, moves to a predetermined position on the storage shelf 2 where it should be stored. The transport head 7 is moved by three axes operating in the X, Y, and θ directions shown in the figure until it reaches the compartment 2°, and the θ axis is used to move the tip of the transfer head 7 toward the compartment 2°. Rotate. During this θ coordinate movement of the tip, the actuator 14 rotates the chuck 13 and the fingers 11 in the 01 axis direction to correct the posture in order to keep the posture of the mechanical unit 1 held by the fingers 11 constant. ing.

While holding the mechanical unit 1 te, the tip of the transfer head 7 is transferred to the front of a predetermined compartment 2 of the storage shelf 2 to be stored, and the mechanical unit 1 is moved to the compartment 2 by performing the above-mentioned chuck operation in reverse order. It is stored in °.

Through the above operations, this device moves the mechanical unit 1 to the storage shelf 2.
Attachment/detachment and exchange are performed between the and installation stand 3.

Inside the storage shelf 2, there are compartments 2', 2'.

A mechanical unit 1 in which a tape reel 6 of necessary electronic components 30 is set in advance is stored in 2°..., and the contents of the electronic components and the area of the storage shelf 2 are stored in the control device in a 1:1 ratio. When this device replaces the mechanical unit 1 and the layout of the internal mechanical unit 1 of the storage shelf 2 is changed, the storage contents of the control device are also updated. Further, the mechanical units 1 stored in the storage shelf 2 are replenished by an operator from behind the storage shelf 2.

The advantage of this embodiment is that the number of storage units per mechanism unit 1 is larger than that of conventional equipment of the same size, and the compact equipment can handle high-mix, low-volume production.

(Second Embodiment) The configuration of the second embodiment will be explained based on FIGS. 2, 3, and 4.

Similar to the first embodiment, a storage shelf 2 is installed near the installation stand 3 of the mechanism unit 1 of the automatic electronic component mounting machine, and a transport device 4 is placed between them. Further, an exchange station 17 is installed between the installation table 3 and the conveyance device 4. The exchange station 17 is attached to the main body base of the electronic component mounting surface, and is equipped with a drive source (motor) for moving the entire station in the X-axis direction (FIG. 4) and an X-axis direction.
The axial movement guide and the mechanical unit 1 are moved in two directions (

It is composed of a bottle 20 that can be inserted into and removed from a small hole 19 at the end of the unit 1 from above, a detachable head 2], and a slide unit 23 that allows the detachable head 21 to be moved by a pneumatic cylinder 22 in the Z direction in the figure.

Further, a storage shelf 2 similar to that of the first embodiment is installed, and a mechanical unit 1 is stored in each compartment 2'', 2°, 2'', etc. of the storage shelf 2, and the mechanical unit 1 is shown in FIG. Needless to say, a tape reel 6 for supplying chip-shaped electronic components 3o by taping is preset, and a transport head 7 is attached to the transport device 4, and the transport head 7 is connected to a mechanism. The finger 11 that grips the unit 1, the chuck 13 that drives the finger 11, and the entire finger 11 and chuck 13 are linked to the angle θ of the above-mentioned transport head 7, so that the mechanical unit 1 is always transported in the same posture. The tip of the conveying head section 7 is constituted by a connecting section 33 equipped with an actuator 14 that is rotatably driven. Furthermore, the entire head section 7 is composed of a linear motion guide member 15 that allows the entire tip section to slide in the Z direction, a cylinder 16 that serves as its driving source, and a connecting section 10 that connects the entire head section with the support base 8. There is. \The operation of this embodiment is similar to that of the first embodiment, but differs in the following points.

It is transferred from the exchange station 17 to the installation stand 3. At this time, storage on the installation stand 3 is carried out to a predetermined location by moving the main body of the electronic component automatic mounting machine using the installation stand movement mechanism. Similarly, the transfer from the installation stand 3 to the exchange station 17 is performed.

As described above, when replacing the tape, the transport device 4 should move the mechanical unit 1 to be newly mounted on the installation stand 3 from the storage shelf 2 to one side of the exchange station 17, and at the same time remove it from the installation stand 3 of the electronic component automatic mounting surface. The drive shaft of the installation stand 3 of the automatic electronic component mounting machine acts to eject the mechanical unit 1 to the other side of the exchange station 17, and the transfer mechanism of the exchange station 17 moves the mechanism unit 1 from the installation stand 3 to the exchange station 17. will be moved to.

The conveyance device 4 grasps the unnecessary mechanism unit 1 ejected from the installation stand 3 and transferred to the exchange station 17, stores it in the storage shelf 2, and at the same time picks up the unnecessary mechanism unit 1 that has been delivered from the storage shelf 2 to the exchange station 17. The unit 1 is supplied to the installation stand 3 of the electronic component automatic mounting surface by the transfer function of the exchange station 17.

The effect of the wooden embodiment is that the mechanical unit 1 can be discharged from the installation stand 3 and supplied from the storage shelf 2 at the same time, and the takt time of the apparatus can be significantly shortened. Particularly in high-mix, low-volume production, the number of setups and the number of tape feeding mechanisms that need to be replaced each time tends to increase, so the reduction in takt time of this device is extremely important for the above-mentioned high-mix, low-volume production.
