Abstract

PURPOSE:To enable the easy and safe fitting of a parts supply case, by constructing tiltably a support table supporting a parts case fitting means, a working element and a parts feeding element, and by providing a means of shifting the direction of the feeding operation of the parts feeding element in accordance with the direction of inclination. CONSTITUTION:When an IC supply case 40 for supplying ICs to be corrected is fitted to a first IC case fitting port 23, an IC holding case 41 for holding corrected ICs is fitted to a second IC case fitting port 24. On the occasion, a support table 20 is rotated counterclockwise by operation levers 36 and 37, an thereby the fitting port 23 is positioned on the upstream side and the fitting port 24 on the downstream side. A switch 33 gives a control unit 35 a detection signal signifying this inclined state, and thereby an IC feeding roller 25 is controlled to rotate so as to ICs onto the downstream side. A correcting roller of a correcting element 22 is also controlled to rotated so as to feed the ICs in the same direction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a parts workbench, and more particularly to an ICIJ-y correction table for correcting the leads of a dual inline package (DIP) type IC in a predetermined direction.

As is well known in the prior art, the lead 9 of the DIP type IC extends downward so as to form a substantially U-shape with the main body or package, and is inserted into a through hole of a printed circuit board. Generally, in a finished product of this type of IC, the tips of the leads are slightly opened outward to form a 6"-shape, and because they are difficult to insert into the through-hole as they are, they are corrected so that they point straight downward.

FIG. 5 shows a conventional r c + )-t° correction table. The support stand 10 has a slope 11, and an I CIJ is provided at the center thereof.
- A correction section 12 for correcting the curvature is attached. Orthodontic department 1
2, as shown in Fig. M6, a correction table 52 that straddles the lead 51 of the IC 50, and a correction roller 53a that presses the RC lead 5t against the sides 52a, 52bζ of the correction table 52 to correct it to a predetermined angle or direction. , 53b. The supply port 13 on the upper side of the straightening section 12 has an unstraightened XC.
An IC supply case 14 is attached to supply the correction part 12.
The XC that stores the straightened XC in the discharge port 5 on the lower side of the
The storage case 16 is attached. Both the IC supply case 14 and the XC storage case 16 are made of a cylindrical body as shown in FIG. 7, and have a protrusion B on the bottom for allowing the IC+7- card 51 to straddle thereon. The IC50 can enter and exit through the case opening C at one end of the cylindrical body A.
The IC supply case 14 and the IC storage case 16 are arranged so that their case openings C face each other from both sides of the correction section 12.
ζ is installed.

As a result, the IC supply case 14, correction section 12 and I
The C storage case 16 forms an inclined IC movement path from the upstream side to the downstream side in this order.

An IC feed roller 17 is provided at the top of the correction section 12 for feeding the IC toward the discharge port 15, that is, to the downstream side.

Since the IC supply case 14 is inclined, the unstraightened IC contained therein slides down to the supply port 13 under its own weight. Next, the uncorrected IC is transferred to the feed roller 17.
While being fed by the correction unit 12, the correction rollers 53a, 5
3b corrects the direction of the lead. corrected IC
is sent to the discharge port 15 side by the feed roller 17 and slides into the case from the case opening C of the RC storage case 16.

The IC storage case 16 that has finished storing the corrected ICs is removed from the discharge port 15, the case opening C1 is capped, and the IC storage case 16 is moved to another location. On the other hand, after the empty IC supply case 14 is removed from the supply port 13,
5 and used as an RC storage case. A new IC supply case 14 containing an uncorrected rc in the supply port 13J is attached.

Thereafter, the ICIJ-de correction operation as described above is repeated.

Problems to be Solved by the Invention However, in such a conventional IC lead correction stand, when the IC supply case 14 containing an uncorrected IC is attached to the supply port 13, the case opening C of the IC supply case 14 is Since the IC faces downward, it is necessary to press the case opening C with a finger to prevent the IC from falling out from inside, and the installation work is difficult and time-consuming.
It is also extremely dangerous when the feed roller 53b and the feed roller 17 are rotating. In addition, the empty IC supply case 1
There is also the inconvenience that the liquid must be transferred from the supply port 13 to the discharge port 15. These inconveniences and inconveniences are also caused by the above-mentioned ICIJ-do correction table, as well as the inspection table where IC characteristics are inspected while the IC is being transferred from the IC supply case to the IC storage case, and the chip correction table from the chip supply case to the IC storage case. This can also be seen on a stamping stand, etc., where markings such as part numbers are applied to chip components while they are being moved to a component storage case.

Means for Solving Problems In the present invention, first and second component case mounting means are configured to selectively mount either a component supply case or a component storage case, and a predetermined task is performed. and a component feeding section that sends the components to the downstream side. and a second inclined state in which the second component case mounting means is in an upstream position and the first component case mounting means is in a downstream position, and a substantially horizontal state. ,
Furthermore, means is provided for switching the feeding direction of the component feeding section according to the direction of inclination of the support base.

When the operation support is in the first tilted state, the component supply case is attached to the first component case attachment means, and the component storage case is attached to the second component case attachment means;
The component feeding section operates to feed the component toward the second component case mounting means on the downstream side. When the predetermined work has been completed on all parts, the support stand is placed in a substantially horizontal state, the parts storage case containing the worked parts is detached from the second parts case mounting means, and the work parts are replaced with the parts storage case. Attach the new parts supply case to the second parts case -\ and attaching means. The empty component supply case becomes a component storage case and remains attached to the first component case attachment means. Next, the support base is placed in the second inclined state, and the component feeding section operates to feed the component toward the first component case mounting means on the downstream side.

In this way, the support table Ltm1 and the second tilted state are alternately repeated once, and work for one component supply case is performed in one tilted state, and after each work is completed, the parts storage case is attached and removed, and a new one is installed. Mounting of the component supply case is carried out only on one component case mounting means with the support stand in a substantially horizontal state.

Embodiment A correction table according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

In FIGS. 1 and 2, an IC! A correction unit 22 for correcting the j-y direction is attached, and first and second IC cases S are installed on both sides of the correction unit 22.
ζ ports 23, 24 are provided.

The correction portion 22 has a groove structure as shown in FIG. 6, as in the conventional case. The first and second IC case mounting ports 23 and 24 are shaped so that the case port C of the IC case A (FIG. 7) can be mounted therein. An IC feed roller 25 is provided above the correction section 22 .

The IC feed roller 25 is moved by a step motor 26# to advance the IC, and its peripheral surface is coated with urethane to provide frictional force. The support stand 20 is rotatably supported by a shaft 29 passed between support plates 27 and 28, and is biased to a substantially horizontal state by springs 30 and 31 disposed on both sides of the support plate 29. . The support plate 27.28 and the spring 30.31 are attached to the base 3
Can be attached to 2. Furthermore, on the base 32 is a support stand 2.
Limit switches 33 and 34 are attached opposite to the bottom surfaces 20a and 20b of 0, and these switches 33 (34
), the support stand 20 is in an inclined state and its bottom surface 20a (2
0b), a detection signal indicating the inclination direction is sent to the control unit 35, and the control unit 35 responds to the detection signal by touching the I
The rotation direction of the C feed roller 25 and the correction rollers 53a, 53b is switched. Operation levers 36 and 37 are attached to both sides of the support base 20 to rotate the support base 20 into a tilted state.

The first and second IC case mounting ports 23 and 24 have I
Either the C supply case or the IC storage case is selectively attached. Now, the first IC case mounting port 23
When the IC supply case 40 for supplying unstraightened ICs is mounted, the straightened ICs are inserted into the second IC case mounting opening 24.
An IC storage case 41 for storing C is attached. In this case, the support base 20 is moved by the spring 30 by the operating lever 36.37.
.

31 and is rotated counterclockwise against the angle 31 so that the IC case mounting port 23 is rotated counterclockwise as shown in FIG. Take a side position. The switch 33 sends a detection signal representing this tilted state to the control section 35, whereby the IC feed roller 25 moves the IC toward the second IC case mounting port 24 on the downstream side.
Rotation is controlled to send. Further, the correction rollers 53a and 53b of the correction section 22 are also rotationally controlled so as to feed the IC in the same direction. In this state, the IC supplied from the IC supply case 40 has its lead direction corrected by the correction table 52 and correction rollers 53a and 53b in the correction unit 22, and is sent downstream by the IC feed roller 25 to the IC.
It is stored in a storage case 41.

When the reed 9 has been corrected for the last IC, the support base 20 is returned to a substantially horizontal state as shown in FIG. On this occasion,
When the bottom surface 20a of the support base 20 separates from the switch 33, the control section 35 stops the rotation of the IC feed roller 25 and the correction rollers 53a and 53b. 'In this state, remove the rc storage case 41 in which the corrected IC has been stored from the second IC case mounting port 24, and replace it with a new IC supply case 43 containing the uncorrected IC.
is attached to the second IC case attachment port 24. The empty IC supply case 40 is then transferred to the IC storage case 40'.
Since it is used as an RC case, it is attached to the first rC case attachment port 23 as it is.

Next, the support stand 20 is moved from the operating lever 36, 374 to the no.
The second IC case mounting means 24 is rotated clockwise against the screws 36 and 37, and the second IC case mounting means 24 is at the upstream position at 8F! The IC case mounting means 23 of No. 1 is located on the downstream side.

A detection signal representing this tilted state is sent from the switch 34 to the control unit 35, and the IC feed roller 25 and correction rollers 53m and 53b are connected to the first IC case mounting port 2 on the downstream side.
The rotation is controlled so that the IC is sent in the direction of 3. In this state, the above-mentioned IC lead 3 correction work is performed, and in this case fc is moved from the IC supply case 43 to the IC storage case 40', and on the way, the direction of the lead is corrected by the correction section 22. After the last IC has been corrected, the support stand 20 is returned to the approximately horizontal state as shown in FIG.
The c storage case 40' is attached and detached, and a new rc supply case is attached, and the above-described operations are repeated.

In the embodiment described above, the switches 33 and 34 cause the support base 2 to
By detecting the tilt direction of 0, the rotation directions of the IC feed roller 25 and the correction rollers 53a, 53b are automatically switched. However, this switching may be performed using a manual switch.

Also, a correction table 52 is used instead of the correction rollers 53m and 53b.
It is also possible to use an orthodontic section equipped with an orthodontic hammer that strikes the ICIJ-de from both sides. Furthermore, although the first and second IC case mounting ports are of a type into which the case opening of an IC case is inserted, other types, such as a binder structure IC case mounting means, can also be used. Also, the operation lever 36.37
may be operated electrically instead of manually.

In addition to the I C Re++ hl correction table, the present invention can be applied to various parts work tables such as an inspection table for inspecting parts and a stamping table for marking parts.

Effects of the Invention In the present invention, since the support stand is in a substantially horizontal state, it is possible to easily and safely attach the component supply case without having to press the case opening with your fingers as in the conventional case, and the support stand can be inverted. By tilting, the empty component supply case can be used as a component storage case in that position, and the conventional effort of moving it to the other mounting position can be saved.
