Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a component mounting device, more specifically, an intermittent rotating support that is equipped with a suction nozzle for suctioning and transferring components, and a predetermined component is suctioned to the suction nozzle at a certain position. For example, a component mounting device that holds electronic components such as chip resistors and chip multilayer capacitors on an electronic circuit board, transfers the component onto an object, and then mounts the component on the object. It is used to attach to.

BACKGROUND OF THE INVENTION The above-mentioned electronic components come in a wide variety of sizes, from 40nX40cm to 1.51nXQ, 3m in size, as well as flat (square) and round shapes. In order to selectively suction, hold, transfer, and mount these parts, a suction nozzle suitable for each part is selected and used, and the parts are reliably suctioned, transferred, and installed. What made this possible was Japanese Patent Application Laid-Open No. 59-1136.
It is known from Publication No. 99.

This device has a turn holder that is repeatedly moved around from a component receiving position to a component mounting position, and this turn holder is appropriately driven by a suction nozzle selection rotation means to select among multiple types of suction nozzles equipped on the turn holder. A predetermined one is selected and used.

Problems to be Solved by the Invention In order to suction and hold various electronic parts, including the above-mentioned micro parts, with suction nozzles suitable for each, and to transport them,
The positional relationship between the suction nozzle and the electronic component must be set more accurately. For example, when holding a microelectronic component by suction with a small suction nozzle that fits it, it is convenient to mount the component on an electronic circuit board in a narrow area commensurate with the microelectronic component, but the misalignment between the suction nozzle and the electronic component The effect of this is large, and even small positional deviations tend to cause air leaks in the component suction state, which may cause the components to fall.

However, in the method of switching the suction nozzles by rotating the turn holder, it is difficult to properly position each suction nozzle to the use position, and it is complicated and difficult to properly position the suction nozzles.
Expensive switching mechanisms are required. In addition, since the rotary switching of each suction nozzle is performed in a state where further rotation is permitted except in certain cases, a positioning operation means movable between the positioning position and the non-positioning position is required. Since the rotational inertia greatly affects the stability of the positioning operation, quick switching cannot be expected.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an intermittent rotation motor of the support body around the intermittent rotation support body.

Multiple types of suction nozzles for suction and transfer of parts are provided at equally spaced positions corresponding to the The present invention is characterized by comprising a nozzle switching means for advancing the nozzle to the use position.

The sliding movement of the suction nozzles may be performed individually, in groups, or as a whole by various driving means such as air cylinders or solenoids. The driving means includes:
Of course, other types than the reciprocating type may also be used.

Multiple kinds of frequent suction nozzles, which are installed at equally spaced positions around the intermittent rotation support, are rotated by the intermittent rotation support, and during this movement, a predetermined nozzle is selectively moved to the use position by the operation of the nozzle switching means. The corresponding parts are sucked and held and transferred to the parts mounting position. The previously used suction nozzle is slid back to the non-use position by the operation of the nozzle switching means when the predetermined suction nozzle is slid into the use position. In short, the plurality of suction nozzles are slid back and forth between a use position and a non-use position by the nozzle switching means to switch which ones are used.

Embodiment FIGS. 1 and 2 show an embodiment in which a plurality of suction nozzles are switched by sliding them all.

As seen in FIG. 1, an intermittent rotation support 1 that is intermittently rotated around a vertical axis has a plurality of radial arms 1a formed in correspondence with the intermittent rotation pitch of the support 1,
Two different types of suction nozzles 2.3 are each equipped at the tip of each arm 1a. The suction nozzles 2.3 on each arm la are lined up in the radial direction of the support 1 and are slidable in the radial direction of the arm 1.
The two suction nozzles 2.3 are alternatively moved to the use position A by sliding the holder 4 forward and backward by an air cylinder 5 connected to the slide boulder 4 built in the holder 4. be positioned.

The suction nozzle 2.3 is inserted into the holder 4 so as to be able to move vertically as shown in FIG. An upward force is applied by. Arm 1
A forward/backward guide portion 1c for the holder 4 and forward/backward stop bars 1d, 1e are provided in the tip of the holder 4a.

The suction nozzles 2.3 set to the use position on the arm la are moved intermittently by the intermittent rotation of the support 1 to their arrangement pitch on the same rotation path, and are moved to a common stop position for each. are advanced sequentially. Rear stop position i of each of those stop positions! ? An X-direction moving table 6 that is reciprocated in the X-direction is provided below S1 for juxtaposing parts supplying forces for supplying various parts individually, and below the front stop position s4, which is opposite to the above, An XY direction moving table 7 that is moved in the X direction and the Y direction perpendicular thereto,
It is provided as a mounting table for adjusting the position of the electronic circuit board 8.

At one part of each of the stop positions WS1 and S4, the suction nozzle 2 or 3, which is set to the use position, is temporarily moved by a predetermined amount against the spring 15 in order to pick up and mount the parts. A lever mechanism 9 and IO for lowering is provided.

Moreover, above the stop position S3 before the stop position s4, there is a nozzle rotation mechanism that temporarily contacts the upper end passive part 1 of the suction nozzle 2 or 3 set in the use position and rotates it by friction. 12 is provided to change or correct the mounting direction of the component. Although not shown in the drawings, the other stop devices S2, S5, and S6 are also equipped with means for positioning the parts relative to the suction nozzles 2 and 3, means for detecting the orientation or position of the parts, and means for discharging defective parts. etc. will be provided as necessary.

Since the suction nozzle 2.3 may be rotated, the collar 1 allows the suction line 13 to rotate freely relative to the nozzle 2.3.
Connected via 4.

The following describes a series of operations: Suction nozzle 2.3
Before reaching the stop position s1, the part corresponding to the next part to be received is set to the use position A by the operation of the air cylinder 5, and the selected predetermined suction nozzle 2 or 3
picks up a predetermined part selectively given by the movement of the X-direction moving table 6 at the stop position S1, reaches the stop position s4 via each stop position S2 and S3, and is moved to the position in the XY direction by the XY-direction moving table 7. The big amplifier component is mounted at a predetermined position on the adjusted electronic circuit board 8.

FIG. 3 shows another embodiment, in which three suction nozzles 21, 22, 2 are provided at the tip of the arm 1a of the intermittent rotation support 1.
3 is equipped. Each nozzle 21.22.23 can be slid back and forth independently of the other between a use position and a non-use position by a solenoid 27.28.29 individually connected to the respective holder 24.25.26. Each of the advancing and retreating directions is a radial direction from the same use position iA, and each holder 24, 25, 26 is guided by a guide 3°. The forward and backward strokes of each nozzle 21.22.23 are regulated by respective elongated holes If, 1g, and 1h of the arm 1a from which the nozzles 21.22.23 protrude.

In the case of this embodiment, the alternative advancement of each suction nozzle 21, 22, 23 to the use position A is such that the nozzle in the use position is first slid back to the non-use position, and then the predetermined nozzle is used. This is done by sliding forward to position A.

In the embodiments described above, the suction nozzle is positioned at the use position on the nozzle side, but the present invention is not limited to this, and the stroke regulation of the air cylinder or solenoid itself on the driving means side can also be performed, for example.

Effects of the Invention According to the present invention, when a plurality of types of suction nozzles are selectively moved to the use position and one is selectively used according to the handled part, the suction nozzle is switched to the use position. Because it uses a sliding movement method, positioning to the usage position is easy.
The stroke can be controlled accurately by simple stroke regulation using a fixed positioning means at the end of the sliding movement, resulting in a simple and inexpensive device.The suction nozzle used is precisely opposed to the parts to be suctioned, so even minute parts etc. can be air-free. It can be reliably adsorbed and transferred without leakage. Furthermore, since the movement inertia of the suction nozzle hardly affects the positioning by the fixed positioning means, the suction nozzle to be used can be quickly switched, and the speed of the component mounting apparatus can be increased.
