DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a component manufacturing and mounting system 2 for mounting electronic components (leadless components) at predetermined positions on printed circuit boards and the like.

BACKGROUND OF THE INVENTION In recent years, as leadless electronic components (chip components) have become widespread, they come in a wide variety of shapes and sizes, and devices that combine these electronic components to form electronic circuits are becoming faster and more reliable. It's been requested.

An example of the above-mentioned conventional mounting device will be described below with reference to the drawings. FIGS. 6 and 7 show a conventional electronic component mounting apparatus. In FIG. 6, reference numeral 1 indicates a suction position where a component is suctioned by a suction nozzle. 3 is a large adjustment position where the dog parts sucked by 11 large adjustment units are adjusted.

Reference numeral 4 denotes a small adjustment position where small parts picked up by 12 small adjustment units are adjusted. Step 5 is component detection to detect components. 6 is a mounting position where components are mounted on a printed circuit board. Reference numeral 8 is a defective discharge position for discharging the parts detected to be defective at the detection position 5. 9 is a suction nozzle switching position for switching between large and small suction nozzles. 7th

Reference numeral 26 denotes a regulating claw which is closed with a constant regulating force by a spring built into the regulating unit main body. Reference numeral 23 is a rod that is incorporated into the regulating unit 26 and moved back and forth to open and close the regulating pawl 25. 24 is 13 with bracket
is body-based. The regulating unit main body 26 is fixed to the main body base 13 with 24 brackets. 2
A block 1 is fixed to a rod 23 with a nut 22.

20 is attached to block 21 by a roller. 17 is fixed to the bracket 24 by a bracket.

19 is attached to the bracket 17 with a shaft. Reference numeral 18 denotes a lever which swings around a shaft 19 and causes the roller 2o attached to the roller 21 to move back and forth. 14 is a connecting rod and 16 is a rod end. The connecting rod 14 is the nut 1

It is fixed to the lever 18 at. 28 is a suction nozzle. Reference numeral 29 denotes a part that is sucked to the tip of the suction nozzle 28 and then lowered by a certain stroke and then raised after being regulated by the regulating pawl 26.

The operation of the electronic component mounting apparatus configured as described above will be described below. First, suction position 1
When the part 29 is picked up by the suction nozzle 28, it is distinguished whether it is a large part or a small part.

If the sucked component 29 is a large component, it is calibrated at a major calibrating position 3, and if it is a small component, it is calibrated at a minor calibrating position 4.

In the normalization operation of the normal position, the connecting rod moves up by a certain stroke, swings the lever 18, advances the rod 23 through the block 21, and forcibly opens the normalization claw 25. Then, when the suction nozzle 28 descends, the connecting rod 14 causes the rod 23 to retreat through the lifting lever 18. When the rod 23 moves back, the regulating claw 25 moves the component 2 attracted by the spring built into the regulating unit main body 26.
Close it to the correct size. When the adjustment is completed, the connecting rod 14 descends again to advance the rod 23 and forcibly open the adjustment pawl 25. When the regulating claw 26 opens, the suction nozzle rises and moves to the next position.

Go to 5-7 Problems to be Solved by the Invention However, in the above configuration, the large TE unit 11 at three normal positions is placed in the position of the component mounting device.
Since only two types of adjustment units, ie, the small adjustment unit 12 at the small adjustment position 4, can be used, there is a problem that parts having different shapes cannot be adjusted.

The present invention makes it possible to regulate parts, etc. that have different shapes, which is the problem described in item 1 above.

In FIG. 2, 48 is an index. 47 is a clutch brake that transmits the rotation from the gear 48 to the index 46. A flange 51 holds the entire axis of the index 46 with a bearing 52. Reference numeral 66 denotes a rotary table, which is fixed to the axis of the index 46 and rotated by an arbitrary angle. 36 is a cam, shaft 3
Rotates around 7 as a fulcrum. 36 is a bracket that holds the shaft 3. A lever 68 swings about the shaft 40 as a fulcrum. A rotating roller 38 is attached to the tip of the lever 68 to interlock the rotation of the cam 36 with the lever 58. 4
Reference numeral 1 denotes a spring, which supports the lever 6 with the bolt 42 as a fulcrum.
8 to make the rotating roller 39 always follow the cam 36. 43 is fixed to the lever 58 at the rod end.

A connecting shaft 45 is fixed to the rod end with a nut 44, and converts the swinging motion of the lever 6 into a linear motion. 6
0 is a flange, which holds the connecting shaft with a slide bearing 49. 34 is a rotatable table, on which a plurality of suction nozzles 67 are arranged, and is moved up and down at a certain position by rollers 68. 6B is a component, which is sucked by suction nozzle 6.

In FIG. 4, reference numeral 57 denotes a regulating claw, which is normally closed by a spring built into the regulating unit main body 66. Reference numeral 69 denotes a rod which, when pushed into the regulating unit main body 66, forcibly opens the regulating claw 57.

Reference numeral 62 denotes a lever that swings about a shaft 64 and transmits the operation of the connecting shaft 45 to the O-) drawer 8.

This electronic component mounting apparatus will be described in more detail with reference to FIGS. 1 to 4. 1 is a layout diagram of the electronic component device, FIG. 2 is a mechanical diagram, FIG. 4 is a detailed diagram of a regulating unit, and FIG. 3 is a plan view of FIG. 4. In these figures, a component 41 that has been suctioned by suction nozzle 6 at suction position 1' is moved to normal position 4' by rotary table 34. At that time, the rotary table 340
Since the rotary table 66 to which the rotation table 66 and the adjustment unit main body 66 are attached can be synchronized with the operation of the clutch brake 47, the rotation table 66 is rotated when the rotary table 34 is rotated, and the adjustment unit is rotated. The main body 66 can be switched. When shifted to the normal position 4', the suction nozzle 67 is lowered by the roller 68. When the lowering is completed, the lever 58 is operated by the cam 36, and the connecting shaft 4 is
6 is raised, and the lever 66 pushes the rod 59 outward by a certain stroke. By pushing out the load 59, the regulating claw 67 is moved to the regulating unit main body 6.
6 is closed until the part 68 is regulated by a built-in spring. When the adjustment is completed, the lever 68 is raised by the cam 36, and the lever 66 pushes the rod 59 inward to forcibly open the adjustment claw 67. When the regulation claw opens, the suction nozzle 67 rises and moves to the next detection position 6.
', detects the component 68, and moves to the next mounting position 6.
At ', the component 68 is mounted on the printed circuit board. Note that when switching the regulating unit main body 66 to the rotary tip 1o by rotating the pull 65, the lever 62 and the rotary roller 53 are in the same position, so when the rotary table 65 is rotated, the groove of the lever 62 is automatically moved. and rotating roller 65
are interlocked.

In addition to the effects of the invention, the present invention arranges a plurality of adjustment units for adjusting electronic components around a rotatable table at a component adjustment position to suit the size and shape of the electronic components picked up at the suction position. Since it is possible to select a standard regulation unit, it is possible to correspond to the regulation of any part. Further, since the rotation of the suction head table and the rotation of the regulation unit rotary table can be rotated synchronously, the regulation unit can be switched at high speed.
