[0001]

The present invention relates to an electronic component feeder for supplying an electronic component (chip) to an electronic component mounter.

[0002]

2. Description of the Related Art As an electronic component mounter for mounting electronic component chips on a printed circuit board, there is an electronic component feeder for supplying electronic component chips such as resistors and capacitors one by one.

As a mechanism for positioning the electronic component feeder on the electronic component mounter as described above, there are a mechanism using a spring force as shown in FIG. 6 and a mechanism using a toggle mechanism as shown in FIG. .

For example, as shown in FIG. 6, an electronic component feeder 1 positioned by a spring force is inserted into a slot (both not shown) provided in an electronic component mounter from the left end in the figure. In this configuration, electronic component chips (not shown) are sequentially supplied to the position of the suction nozzle 2 of the electronic component mounter.

[0005] Reference numeral 3 in FIG. 6 denotes a handle, and when the electronic component feeder 1 is attached to or detached from the electronic component mounter, the operator holds the handle 3 and works. The electronic component feeder 1 includes a stopper lever 5 that engages with a lock shaft 4 on the electronic component mounter side when the electronic component mounter is mounted on the electronic component mounter, and an opening / closing lever 7 that drives the stopper lever 5 via a link 6. .

The stopper lever 5 is swingably supported by a support shaft 8 and has a tip 5A at a lock shaft 4A.
6 by a spring 9 on the other end 5B side so as to engage with FIG.
Are biased clockwise.

The opening / closing lever 7 is swingably supported by a support shaft 10 at an intermediate position in the longitudinal direction. When the operating end (upper end in the figure) is operated clockwise, a stopper lever is provided via the link 6. 5 is pivoted counterclockwise in the figure to release the engagement between the tip 5A and the lock shaft 4.

The tip 5A of the stopper lever 5 is shown in FIG.
As shown in (2), when the electronic component feeder is mounted on the electronic component mounter, the lock shaft 4 is provided with an inclined surface 5C which comes into contact with a lower surface on the inner side of the loading side and an inclined surface 5D on the distal end side in the loading direction. .

When the electronic component feeder 1 is mounted on the electronic component mounter, the stopper lever 5 is urged clockwise in the figure by a spring 9 to press the inclined surface 5C against the lock shaft 4 so that the electronic component feeder is pressed. 1 and a force for pressing the lock shaft 4 in a direction perpendicular to the loading direction (downward), and the electronic component feeder 1 is positioned and fixed at the mounting position. ing.

Reference numerals 11A and 11B in FIG. 6 denote positioning guide members on the side of the electronic component mounter. When the electronic component feeder 1 is mounted, its tip comes into contact with the positioning guide member 11A to determine the position in the loading direction. In addition, the lower surface of the distal end portion of the electronic component feeder 1 is guided along the positioning guide member 11B so that the electronic component feeder 1 can be inserted and extracted.

A contact surface of the electronic component feeder 1 with the positioning guide member 11A is provided with a positioning shaft 1 in the loading direction.
2 and the positioning guide member 11A at the time of mounting.
The electronic component feeder 1 is positioned in the thickness direction (in the direction perpendicular to the plane of FIG. 6) and in the height direction by fitting into the positioning holes 12A formed in the electronic component feeder 1. In the mounted state, the electronic component feeder 1 tends to swing around the positioning shaft 12, but this is prevented by the contact between the electronic component feeder 1 and the positioning guide member 11B.

Next, the electronic component feeder 14 utilizing the toggle mechanism shown in FIG. 7 will be described.

The electronic component feeder 14 forms a toggle link mechanism with an opening / closing lever 16 and a link 18 driven by the opening / closing lever 16, and a stopper lever 20 swinging via the link 18 has a tip 20A having a lock shaft. 4 is strongly restrained by the toggle force in a state of holding it.

Here, the electronic component mounter side positioning guide member 11C for contacting the bottom surface of the electronic component feeder 14 in FIG. , As shown in FIG. 8, constitutes a linear rail mechanism.

In FIG. 7, the same components as those of the electronic component feeder 1 are denoted by the same reference numerals, and description thereof is omitted.

[0016]

In the electronic component feeder 1 shown in FIG. 6, since the electronic component feeder 1 is fixed in the mounted state only by the urging force of the spring 9, the clamping force is insufficient. There is a problem that the electronic component feeder 1 may not be mounted at a correct position.

Further, even after the electronic component feeder 1 is mounted on the electronic component mounter, a slight external force acts when another component or an operator comes into contact with the rear part of the electronic component feeder 1 protruding from the electronic component mounter. Even in this case, there is a problem that the tip may move.

Although the toggle mechanism type electronic component feeder 14 shown in FIG. 7 has a strong clamping force due to the toggle mechanism, the moving amount of the opening / closing lever 16 when the electronic component feeder 14 is attached / detached is limited to the electronic component feeder 1 shown in FIG. There is a problem that it cannot be attached and detached by one-handed operation.

Furthermore, since the clamping force by the toggle mechanism does not always act elastically as in the case of the spring force, the electronic component feeder 14 must be mounted on the electronic component mounter with accurate positioning. No.

Therefore, as described above, the bottom surface 14A of the electronic component feeder 14 and the positioning guide member 11C on the electronic component mounter side must be rail-engaged.
There is a problem that the manufacturing cost increases.

The present invention has been made in view of the above-mentioned conventional problems, and can accurately determine the mounting position without a guide rail mechanism requiring precision machining, and can be operated with one hand. An object of the present invention is to provide an electronic component feeder capable of strongly clamping and releasing a clamp.

The pressing force of the lock shaft 32 by the pressing surface 48 can be set to an optimum value by adjusting the eccentric angle of the eccentric support shaft 43.

When removing the electronic component feeder 30 from the electronic component mounter, the second stopper lever 40 and the stopper lever 34 do not interfere with the lock shaft 32 by swinging the opening / closing lever 42 to the “open” position. The electronic component feeder 30 may be pulled out in this state while being swung counterclockwise to the position.

Reference numeral 54A in FIG.
0, a positioning guide member 54B is provided at an upper position in the drawing of the lock shaft 32 to abut on the tip of the electronic component feeder 30 when the electronic component feeder 30 is mounted.
2 shows a positioning guide member for positioning by slidingly contacting the lower surface of the front side when mounting.

Reference numeral 56 in FIG. 1 denotes a positioning shaft provided at the tip of the electronic component feeder 30. When the electronic component feeder 30 is mounted, it is inserted into a positioning hole 55 formed in the positioning guide member 54A. Mating,
The electronic component feeder 30 is positioned in the thickness direction and the height direction.

Reference numeral 58 in FIG. 3 denotes an adjusting plate attached to the lower side surface of the electronic component feeder 30. The adjusting plate 58 has a long hole 58A, and an adjusting screw is inserted through the long hole 58A. By being attached to the side surface of the electronic component feeder 30 by 60, the projecting position of the lower end thereof can be adjusted.

Next, a process of attaching and detaching the electronic component feeder 30 to and from the electronic component mounter will be described.

First, the open / close lever 42 is operated to the "open" position in FIG. 4A, and in this state, the electronic component feeder 30 is inserted into a slot (not shown) of the electronic component mounter.

At this time, the stopper lever 34 is swung counterclockwise through the link 44 and the second stopper lever lever 40 so that the tip of the stopper lever 34 does not interfere with the lock shaft 32.

When the leading end of the electronic component feeder 30 contacts the positioning guide member 54A and the positioning shaft 56 is fitted in the positioning hole 55, the opening / closing lever 42 is moved to the "closed" position as shown in FIG. Swing to B. As a result, the second stopper lever 40 is
The first stopper lever 34 is not pushed counterclockwise through the claw 50.

Accordingly, the stopper lever 34 is urged clockwise in FIG. 1 by the spring 36, and the positioning inclined surface 46 is pressed against the stopper lever 34 from below.

As a result, the electronic component feeder 30
Since the electronic component mounter is urged in the loading direction and the direction of holding the lock shaft 32, the electronic component mounter is positioned and fixed by the urging force of the spring 36.

In this state, when an external force acts on a part of the electronic component feeder 30, the electronic component feeder 30 may be easily displaced.

Next, when the opening / closing lever 42 is swung to the “toggle position” C in FIG.
B reaches a position on a straight line passing through the eccentric support shaft 43 and the pin 44A (conjecture point), and further moves slightly to the right beyond this connotation point.

As a result, a toggle force acts on the second stopper lever 40, and the pressing surface 48 is strongly pressed against the lock shaft 32 from below.

Therefore, the electronic component feeder 30 is in the locked state, and there is no backlash even when the electronic component feeder 30 comes into contact with a part thereof.

When the second stopper lever 40 is locked, the pressing surface 4 of the second stopper lever 40
8 strongly presses the non-groove portion 32B of the lock shaft 32, as shown in FIG.

At this time, the U-shaped cross section 34A of the stopper lever 34 disposed inside the U-shaped cross section 40A on which the pressing surface 48 is formed is the outer U-shaped cross section. Since there is a gap with respect to 40A, it is possible to swing around the support shaft 35 with respect to the U-shaped section 40A in the locked state. Also, the positioning inclined surface 4
6 is in contact with the tapered surface 32 </ b> C of the lock shaft 32, so that the positioning inclined surface 46 is not
Of the lock shaft 32 by the urging force of
The state of being securely pressed against C is maintained.

Since the electronic component feeder 30 in the above mounted state can swing about the positioning shaft 56, as shown in FIG. 3, the bottom surface 30A of the electronic feeder 30 and the positioning guide member 54B The electronic component feeder 30 may be inclined about the positioning shaft 56 depending on the state of contact with the upper surface of the electronic component feeder 30.

In such a case, the height of the adjustment plate 58 protruding from the bottom surface 30A may be adjusted to correct the adjustment plate 58 to a normal state.

When the tilt of the electronic component feeder 30 is adjusted by the adjusting plate 58, the second stopper lever 40 is also tilted at the same time. Therefore, the inner diameter of the insertion hole 41 is adjusted so as to follow the adjustment by the adjusting plate 58. It is preferable that the backlash is provided to be larger than the outer diameter of 35.

Further, since the crank-shaped link 44 can have elasticity as a whole due to the crank shape, the dimensional error can be reliably absorbed.

In the example of the above embodiment, the second stopper lever 40 is such that the stopper lever 34 is the lock shaft 3.
In a state where the lock lever 32 is pressed, the lock shaft 32 is pressed and locked by the pressing surface 48 independently of the stopper lever 34, but the present invention is not limited to this. For example, as shown in FIG. 5, the height of the U-shaped section 40A is reduced so that the upper end of the U-shaped section does not contact the lock shaft 32,
When the second stopper lever 40 is actuated in the locking direction by reducing the gap with the inner U-shaped section 34A,
The stopper lever 34 may be pressed in the lock shaft 32 direction without pressing the lock shaft 32.

In this case, the engagement force of the stopper lever 34 with the lock shaft 32 is increased by the second stopper lever 40.

Further, in the example of the above embodiment, the second
The stopper lever 40 is provided on the support shaft 3 of the stopper lever 34.
5, but the present invention is not limited to this. The second stopper lever 40 is swingably supported on a support shaft separate from the support shaft of the stopper lever 34. Is also good.

The first stopper lever 34 and the second
Although the stopper lever 40 is adapted to engage with the lock shaft, the stopper lever 40 is not limited to a shaft as long as it is a lock means composed of a member on the tip mounter side.

[0080]

According to the present invention, the second stopper lever is strongly engaged with the lock means by the toggle force directly or through the stopper lever in the positioning state by the stopper lever having the positioning inclined surface. In addition, the electronic component feeder can be securely fixed. Further, these processes can be performed by one-handed operation of the opening / closing lever.
