Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a technique for supplying chip components, and in particular to a technique that is effective for supplying chip-shaped electronic components to a chip mounter.

[Conventional technology]

When mounting chip-shaped electronic components such as semiconductor devices, resistors, and capacitors on a board, etc., the chip components are held in rows at predetermined intervals on tape, and the tape is fed from a tape supply unit such as a tape reel. It is conceivable that by intermittently feeding the chip to the chip take-out section, the chip is taken out from the tape to the chip mounter at the chip take-out section and mounted on the board by the chip mounter.

[Problem that the invention attempts to solve]

However, this type of chip component supply technology that is generally considered to have an independent drive source for supplying chip components, separate from the drive source for the chip mounter. Therefore, there are major problems in that the structure of the chip component supply device becomes complicated and large, and the cost also increases.

Therefore, the present applicant filed the Utility Model Application No. 62-144255.
No. 61-29401) proposes a chip parts supply device that has a simple structure, is small in size, and can be manufactured at low cost. This chip supply device is constructed so that the tape guide interval can be changed in accordance with a change in the width of the tape, and the tape feeding pitch can be changed in accordance with a change in the chip component arrangement pitch.

The inventor of the present invention conducted further intensive research on this type of chip component feeding device and discovered that the following problems should be solved.

First of all, the tape covers the chip parts with protective tape or seal tape in order to hold the chip parts in the chip part holding hole of the holding tape, which is the tape body, so this protective tape is used to remove the chip parts. must be peeled off from the retaining tape. If the protective tape is simply left hanging after being peeled off, there are problems such as a worker getting caught in the protective tape, hindering smooth work, and accumulating static electricity.

Second, after the protective tape has been peeled off, the chip component is removed from the holding tape at the chip component removal position, but in the process from the peeling position to the removal position, the chip component is exposed to vibrations and other external forces that cause the chip component holding hole to open. There is a risk of it flying out.

Third, if the thickness of the tape changes due to changes in the thickness of the chip parts or manufacturing errors, if this change in thickness is not properly absorbed, it will be difficult to remove the chip parts from the holding tape or feed the tape. There is a possibility that it will become certain.

One object of the present invention is to provide a chip component feeding device for a chip mounter having a simple and compact structure.

Another object of the present invention is to provide a chip component feeding device for a chip mounter that can prevent the protective tape that has been peeled off from the holding tape from hanging down and interfering with work or from accumulating static electricity. .

Still another object of the present invention is to provide a chip component feeding device for a chip mounter that can prevent chip components from flying out from the holding tape after the protective tape is peeled off.

Yet another object of the present invention is to provide a chip component feeding device for a chip mounter that can appropriately absorb changes in tape thickness.

[Means for solving problems]

The chip component supply device for a chip mounter of the present invention includes an actuation lever having first, second and third arm parts, and applies an actuation force applied to the first arm part of the actuation lever to the drive source of the chip mounter itself. By driving the actuating lever with the driving force from the driving source of the chip mounter, the intermittent tape feeding means is interlocked and connected to the second arm of the actuating lever; A protective tape peeling means operatively connected to the arm section 3 is operated in conjunction with the protective tape peeling means.

Further, the tape feeding means is configured as a tape feeding pawl that is interlocked and connected to the second arm portion of the operating lever, and the tape feeding pawl portion at the tip of the tape feeding pawl is inserted into the pitch feeding hole of the tape and By pushing the tape in the feeding direction, the tape is intermittently fed at predetermined pitches, and a part of this tape feeding claw is used to prevent the chip parts from popping out from the chip part holding part of the tape after the protective tape is peeled off. It comes into contact with a shutter member covering the chip part holding part so as to hold the chip part holding part, and urges the shutter member in the chip part holding direction against the biasing force of the spring.

Further, the protective tape peeling means includes a protective tape take-up reel that peels off and winds the protective tape peeled off from the tape every predetermined length.

Further, the tape that is intermittently fed by the tape feeding means is guided by the fixed guiding means and the movable guiding means, with their upper and lower surfaces sandwiched between them, and the movable guiding means moves in the tape feeding direction according to the thickness of the tape. It is supported by flexible elastic means, such as a pair of leaf springs inclined in the tape feeding direction.

[Effect]

According to the above-mentioned means, the driving force of the chip component supply device is given from the drive source of the chip mounter itself, so the structure is simpler and more compact than a structure in which the chip component supply device itself has its own special drive source. can get.

Furthermore, since a shutter member is provided to prevent the chip components from flying out from the tape after the protective tape is peeled off, the chip components can be reliably removed by the chip component removal means of the chip mounter.

Furthermore, by providing the protective tape take-up reel in conjunction with the operating lever, it is possible to prevent the protective tape from hanging down after being peeled off and interfering with the work.

In addition, when the thickness of the tape is changed by guiding the tape being fed from both the upper and lower sides by a fixed guide means and a movable guide means, and supporting the movable guide means by an elastic means that bends in the tape feeding direction. However, since the change in thickness can be absorbed by the movable guide means, it can be used universally for various tapes with a wide range of thickness dimensions, and chip parts can always be reliably removed from the tape. .

A roller 23 is vertically attached to the first arm portion 20 of the actuation lever 17 . This roller 23 is moved by the arm 27 and the rod 28 by vertical movement of a piston rod 26 of an air cylinder 25 (drive source) provided on the frame 24 of the chip mounter 2.
A downward driving force is applied in the direction of arrow A by the actuating head 29 via. That is, the driving force to the operating lever 17 is commonly applied by the air cylinder 25 which is the driving source of the chip mounter 2 itself. Therefore, in this embodiment, there is no drive source unique to the chip component supplying device, and the entire device has a simple and compact structure.

In addition, the piston rod 26 of the air cylinder 25
The main body 13 of the chip mounter 2 is connected to the operating head 29.
The arm 30 is connected to the main body 13 via an arm 30 so as to be interlocked vertically.

On the other hand, the second arm portion 21 of the actuating lever 17 has a tape feed pawl 31 at its tip for intermittent feeding of the tape.
(tape feeding means). This tape feed pawl 31 is biased clockwise by a spring 32.

The tip of the tape feed claw 31 is inserted into the pitch hole (not shown) of the tape 5 to be guided by being sandwiched between the upper fixed guide plate 33 and the lower guide block 34 (movable guide means) from above and below. The tape 5 is intermittently pitch-fed by a predetermined length. The tip of the tape feed claw 31 is connected to the fixed guide plate 3
When it is displaced from the notch 33a (FIG. 3) of No. 3, it rides on the upper surface 33b of the fixed guide plate 33 and does not engage with the pitch hole of the tape 5.

The tip surface of this tape feed claw 31 contacts the shutter member 35, and the shutter member 35 is moved in the tape feeding direction against the biasing force of a tension spring 36 stretched between the shutter member 35 and the fixed guide plate 33. (1st
(rightward in the figure). This shutter member is for holding the chip part 4 so that it does not fly out from the chip part holding hole 7 of the holding tape 6 after the protective tape 9 is peeled off. Therefore, the tip of the shutter member 35 (the right end in FIGS. 1 and 5) is attached to the tape 5 with respect to the tape feeding direction.
This bent portion serves as a shutter portion 35a and covers the upper part of the chip holding hole 7 to prevent the chip 4 from flying out. The shutter member 35 is the tape feed claw 3
1 is not biased in the tape feeding direction, it is pulled in the opposite direction to the tape feeding direction by the tensile force of the tension spring 36.

Furthermore, the third arm portion 22 of the actuating lever 17 is interlocked with a pawl 37, and the tip of the pawl 37 engages with a pawl of a ratchet wheel 38 attached to the frame 11. 38 is intermittently rotated only in one direction, that is, clockwise. This ratchet wheel 38 has pin 3.
Take-up reel 4 for winding the protective tape around 9
Rotates in conjunction with 0.

That is, the third arm portion 2 of the actuation lever 17
2 moves counterclockwise, the ratchet wheel 38 is intermittently rotated clockwise by the pawl 37, and in conjunction with this, the take-up reel 40 is also rotated clockwise, thereby removing the holding tape 6 from the ratchet wheel 38. The peeled off protective tape 9 is attached to the tip of the fixed guide plate 33 (the first
It is folded back in the direction of the take-up reel 40 (at the right end in the figure), and is intermittently wound around the take-up reel 40 at predetermined length intervals. Therefore, in this example,
It is possible to prevent the peeled off protective tape 9 from hanging down and interfering with work, and from causing static electricity to accumulate.

Further, as shown in FIG. 1, the guide block 34 (movable guide means) is supported by a pair of mutually parallel leaf springs 41 and 42 (elastic means) so that it can be elastically bent. The leaf springs 41 and 42 are provided to be inclined in the feeding direction of the tape 5 in order to apply an urging force to the tape 5 in the return direction.

The lower ends of both leaf springs 41 and 42 are connected to the adjustment block 4.
It is attached to 3. The adjustment block 43 can adjust the biasing force of the leaf springs 41 and 42 against the guide block 34 by changing the mounting position using the screw 44 along the elongated hole 45 of the frame 11. Both blocks 34 and 43 and both leaf springs 41 and 42 are parallel to each other and form a parallelogram.

The frame 11 can be detachably attached to the base 46 of the chip mounter 2 with pins 47 in the lower right portion of FIG.

Next, the operation of this embodiment will be explained.

First, the chip parts 4 are housed in the chip part holding holes 7 at a predetermined pitch, and the tape 5 whose upper part is covered with the protective tape 9 is wound around the reel 10.
0 is rotatably mounted on the frame 11 in the tape supply section 1. Then, the tape 5 is routed between the roller 12, the fixed guide plate 33, and the guide block 34, and further around the block 16 as shown by the two-dot chain line in FIG.

When the chip component supply device of this embodiment is operated, when the piston rod 26 of the air cylinder 25, which is the drive source of the chip mounter 2, is lowered by a predetermined stroke from the state shown in FIG. The member 14 and the suction nozzle 15 are lowered together with the piston rod 26 via the arm 30 from the solid line position in FIG. 1 to the two-dot chain line position.

In conjunction with this, the operating head 29 of the chip mounter 2 is also lowered together with the piston rod 26 from the solid line position to the two-dot chain line position via the arm 27 and rod 28.

In conjunction with this lowering movement of the operating head 29, the roller 23 of the first arm portion 20 of the operating lever 17
By pushing in the direction of arrow A, the actuating lever 1
7 rotates clockwise as shown by arrow B from the solid line position in FIG. 1 to the two-dot chain line position against the biasing force of spring 19.

As a result, the tape feed pawl 31 interlocked with the second arm portion 21 of the actuating lever 17 moves as indicated by the arrow C.
pulled in the direction. As a result, the tape feed claw 3
The shutter member 35 that had been pressed at the tip of the tape feed claw 31 is released, and the tension spring 36
It moves a predetermined distance to the left in FIG. 1 with a tensile force of . Thereby, the shutter portion 35a at the tip of the shutter member 35 moves from a position above the chip component holding hole 7 of the tape 5 to prevent the chip component 4 from flying out in the opposite direction to the tape feeding direction. Move back to the left in Figure 1 by one pitch.

Since this movement of the shutter member 35 is performed in conjunction with the operation of the suction nozzle 15 of the chip mounter 2, immediately before the suction nozzle 15 descends to the position indicated by the two-dot chain line in FIG. is shifted to the left in FIG. 1 from the position of the tape 5 covering the tip holding hole 7. Therefore, the suction nozzle 15, which has descended above the chip component holding hole 7 without interfering with the shutter member 35a, suctions the chip component in the holding hole 7 with the vacuum suction force from a vacuum source (not shown), and the chip component is removed. Preparations are made for transport to the chip mounter position.

In conjunction with these operations, the pawl 37, which is interlocked with the third arm portion 22 of the operating lever 17, receives a tensile force in the direction of arrow D and moves to the right in FIG. 1.

Next, when the piston rod 26 of the air cylinder 25 of the chip mounter 2 is raised, the pressing force of the operating head 29 against the roller 23 of the first arm portion 20 is released, and the operating head 29, suction nozzle 15, etc. are Returns from the two-dot chain line position to the solid line position. At the same time, the actuating lever 17 is rotated by the biasing force of the spring 19 from the two-dot chain line position to the solid line position in FIG. 1 and returns.

As a result, the tape feed pawl 31, which is interlocked and connected to the second arm portion 21 of the operating lever 17, moves in the tape feed direction, and its tip is inserted into the pitch feed hole (not shown) of the tape 5. By pushing the tape 5 in the tape feeding direction (rightward in FIG. 1) with its tip (tape feeding claw), the tape 5 is
is intermittently fed by one pitch, and the shutter member 35 is driven in the tape feeding direction against the tensile force of the tension spring 36.

At this time, the third arm portion 22 of the operating lever 17
A pawl 37 interlocked with rotates the ratchet wheel 38 clockwise intermittently by a predetermined angle at its tip. As a result, the take-up reel 40 rotates intermittently clockwise in the direction of arrow E, and the protective tape 9 is peeled off from the holding tape 6 and wound onto the take-up reel 40. At the same time, the chip component 4 exposed from the state covered by the protective tape 9 is fed one pitch along with the tape 5 by the tape feed claw 31 while being covered by the shutter portion 35a of the shutter member 35.

In this way, by repeatedly repeating the same interlocking operation as described above, the chip part 4 is moved to the tape 5.
At the same time, the suction nozzle 1 of the chip mounter 2 is fed from the chip component holding hole 7 intermittently every pitch.
After being taken out at step 5, it is sent to a chip mounter position such as a board and mounted thereon by means not shown.

It should be noted that the present invention is not limited to the above embodiments, and various other modifications are possible.

For example, instead of an air cylinder as a driving source, a hydraulic cylinder, a motor, etc. may be used.
