[Detailed Description of the Invention] Industrial Field of Application This invention is a component mounting machine, specifically, capable of reciprocating movement between a component pick amplifier section and a component mounting section, and rotation for changing the direction of held components. A component mounting machine equipped with a component mounting head is used to transport electronic components such as chip resistors and chip ME capacitors to predetermined positions on a board forming an electronic circuit and mount them in a predetermined direction. be done.

BACKGROUND OF THE INVENTION A device of this type is exemplified in U.S. Pat. No. 3,958,740. Now, a component mounting head that sucks and holds a component and removes it from the component mounting head is rotatably held relative to a component mounting head moving body that can reciprocate between the component pick amplifier section and the component mounting section. is reciprocatingly driven or rotated by a reciprocating means equipped on the machine body, and the component mounting throat is driven reciprocatingly or rotationally by a rotating means equipped on a component mounting head moving body, and the reciprocating means and Each of the rotating means is individually equipped with a drive/Us source.

Problems to be Solved by the Invention In the conventional device described above, the reciprocating movement and rotation of the component mounting head are

In addition, the component mounting head moving body is equipped with a rotation means with a drive source, resulting in increased weight and size, which impedes speeding up of operation and improvement in positioning accuracy for component mounting. At the same time, go fjfF
This also leads to the increase in the size of the 5S1 means and guides, further increasing the price of I'Ti.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a component mounting system that allows forward movement between the component pink-up section and the component mounting section and rotation for changing the direction of the held component. In a component mounting machine equipped with a head, a reciprocating means and a rotating means for the component mounting head are provided so as to share a driving source outside the component mounting head moving body.

The reciprocating means directly reciprocates one body for mounting the parts, and the rotating means moves the parts mounting head 1' and Wg, which can be reciprocated during movement or move the parts mounting head relative to the fixed part of the machine. Although it is preferable to configure it so that it is rotationally driven, it is not limited thereto.

The operational reciprocating means can be driven in various types by a drive source external to the component mounting head moving body, and reciprocates the component mounting head between the component pink-up section and the component mounting section. The rotating means is driven by the reciprocating means being driven or relative movement with the body fixing part by the reciprocating means while it is being driven, sharing the one drive source outside the component mounting head moving body, and rotates the throat for component mounting.

Embodiments Embodiment 1 (FIG. 1) FIG. 1 schematically shows the principle of the present invention, in which a vacuum suction type component mounting head 1 is rotatably held by a head moving body 2. The movable body 2 is held by a guide (not shown) so that it can reciprocate in the Y direction between the component pickup section (2) and the component mounting section (2) by the head 1. Along the Y-direction reciprocating path of the movable body 2, the reciprocating belt 3 is connected to a pair of pulleys 4.5.
A reciprocating means 16 is formed by the pulley 4, and a reversible drive motor 6 is connected to one of the pulleys 4. Mobile object 2
Usually, the clamp part 7 for the belt 3 is held on the left and right, and the clamp part 7 clamps the belt 3.
The clamp portion 7 is moved together with the belt 3, and is caused to slide against the belt 3 by an external force exceeding the clamping force.

The component mounting head 1 on the moving body 2 has a suction hose 8
A passive roller 10 is attached to the belt 3 as a rotation means 17, and is connected to the head 1 through a gear connection 18. The driven roller 10 is rotated by the belt 3 due to the relative movement of the movable body 2 and the belt 3 in the Y direction, and transmits its rotation to the head l via the gear connection 18.

An electromagnetic stopper 11, which can move forward and backward, is installed at a predetermined position on the moving route of the moving body 2, so that the movement of the moving body 2 relative to the belt 3 can be stopped for a predetermined period of time.

The component pickup section I is provided with a large number of taping cassette means 12 for supplying components in parallel, and is configured to intermittently supply necessary types of components 15 in a fixed direction in the X direction. After the printed circuit board 13 on which the component 15 is mounted is supplied to the component mounting section H, the position is adjusted according to the mounting of the component,
Furthermore, an X-direction carrier 14 is provided which is discharged after completion of component mounting.

A series of operations for mounting the holding component 15 onto the board 13 from the big amplifier of the component 15 by the head 1 will be described below.

The movable body 2 is moved to the component pickup section I side by the drive of the heald 3, and the head 1 is placed on a predetermined taping center means 12 that supplies the mounted components 15 according to the program.
position. At this predetermined position, the moving body 2 is moved by the heald 3.
The movement of the head 1 is stopped, and the head 1 receives the suction force and picks up a predetermined part 15 by suction. In order to lift up the parts, the head 1 is moved up and down relative to the movable body 2 by means not shown.

When the head 1 picks up the predetermined component 15, the movable body 2 is moved toward the component mounting section (2) by the heald 3 being driven in the opposite direction. The predetermined component 15 held by suction is the board 13
In the case where the electromagnetic stopper 11 is to be attached with a different orientation, the electromagnetic stopper 11 is activated in advance according to the program and advances into the moving path of the moving body 2. For this reason, the movable body 2 comes into contact with the stopper 11 before reaching the component mounting part (2), and its progress is hindered, causing the clamp part 7 to slip with respect to the belt 3 that is being driven. Due to this relative movement between the movable body 2 and the belt 3, the movement of the belt 3 is converted into rotation of the passive roller 10 of the movable body 2 and transmitted to the head 1.

By rotating the head 1, the orientation of the component 15 that is suctioned and held by the head 1 can be changed. The angle of change in direction is set according to a program by adjusting the amount of rotation of the head 1, that is, the time during which the stopper 11 obstructs the movement of the moving body 2. When the stopper 11 is moved back after a predetermined period of time has elapsed, the movement υ1
The body 2 is again moved together with the belt 3, and the orientation-adjusted holding component 15 is transferred to the substrate 13. When the component 15 reaches a predetermined position in the Y direction on the board 13, the heald 3 stops, and the component 15 is placed in the predetermined position on the board 13 positioned in the Y direction by the vertical movement of the head 1 and release of suction. It will be installed.

If a predetermined component 15 to be suctioned and held by the head 1 in the component pickup section I is programmed to be mounted on the board 13 without changing its orientation, the rotation of the head 1 due to the advance of the stopper 11 is not performed.

In the embodiment described above, the clamp part 7 may be clamped and unclamped from the belt 3 at a timely manner by electromagnetic action, etc., and the transmission system from the belt 3 to the head l can be changed in various ways, one of which is as follows. By providing an electromagnetic clutch 19 as shown in the imaginary line and connecting/disconnecting it, transmission control for determining the direction change angle can be performed separately from the movement of the stopper 11. The passive roller 10 is attached directly to the head 1,
Embodiment 2 (FIG. 2) In which the gear connection 18 can be omitted The principle is shown in FIG.
It is fixed to the belt 3 by the clamp part 7, and cannot move relative to the belt 3. A passive gear 21 is attached to the rack l for mounting parts held on the moving body 2, and the rack 22 of the gear 21 along the reciprocating path in the Y direction accompanying the moving body 2 is moved forward and backward in the X direction by the solenoid 23. The head 1 is provided as a rotating means 24 for the head 1.

The rotation means 24 are used to rotate the parts 15 carried by the head 1.
Only when the direction needs to be changed, the solenoid 23 is energized, and the rack 22 is advanced to mesh with the moving passive gear 21. This causes the gear 21 to follow the rack 22,
Rotate head l.

When the head 1 rotates a predetermined angle, the solenoid 23 is de-energized and the rack 22 is separated from the gear 21. As a result, the gear 21 stops rotating, the head 1 is stopped, and the orientation of the component 15 held in the head 1 is changed according to the program.

Therefore, in this embodiment, there is no need for a temporary stop during the movement of the movable body 2 and a stopper therefor as in the first embodiment.

The other configurations and operations are the same as in the first embodiment, and their explanations will be omitted. It is also possible to change the gear 22 and the gear 21 to friction transmission elements.

Embodiment 3 As shown in FIG. 3, the moving body 2 of the component mounting head 1
is operated by a reciprocating means 32 with a glue source as a linear pulse motor consisting of a fixed part 32a which also serves as a guide for the moving body 2 installed horizontally on the body 311, and a movable part 32b provided on the moving body 2 itself. , parts big amplifier section
A reciprocating movement in the Y direction is performed between and the component mounting section (2).

A flexible cable 34 is stretched along the reciprocating path of the movable body 2 in the machine horizontal head 33 equipped with the fixing part 32a, and a part of the cable 34 is connected to the component mounting head 1. The receiving vj roller 35 is wound around a passive roller 35 to form a rotation means 36 for the head l, and the receiving vj roller 35 is connected to and disconnected from the head 1 via an electromagnetic clutch 37.

When the movable body 2 is moved in the Y direction a1 by the reciprocating means 32, the passive roller 35 is always driven by the cable 34 without play or wobbling due to sufficient friction due to its winding. Therefore, the rotation for changing the orientation of the holding part 15 of the head 1 is performed by diachronically turning the clutch 37 (
Connect the roller 35 and the head 1 by connecting the roller 35
This is done by transmitting the rotation of the head 1 to the head 1.

A pair of taping cassette means 12 for supplying components, a component mounting head 1, its reciprocating means 32, and a rotation means 36 are provided in front and rear, and are operated in a cycle having a predetermined phase with each other to supply the required components to the board 13. This reduces the time required for installation.

In this embodiment, as in the second embodiment, there is no need to temporarily stop the moving body midway to change the orientation of the parts, and there is no need to separately provide a moving member such as the rack in the second embodiment.

Each of the following embodiments is an embodiment of the present invention, and the structure of the present invention is not limited, and it goes without saying that various other specific means may be adopted.

Effects of the Invention According to the present invention, the reciprocating means and the rotating means of the component mounting head are operated so as to share one driving source, which makes the device simpler and cheaper. In addition, one drive source is provided outside the component mounting head moving body and drives both the reciprocating means outside the moving body and the moving means above the moving body, so there is no need to equip the moving body with a drive source. The moving body has been made smaller and lighter, which is advantageous for increasing the speed of the FJ+ and improving the positioning accuracy of parts mounting. It will be cheap.
