Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic insertion machine for implanting or inserting electronic components onto a board, and particularly relates to a board transfer device in such an automatic insertion machine.

(Prior art) Conventionally, a board transfer device has a carry-in guide stand and a carry-out guide stand before and after an NC-controlled X-Y table for holding the board, and these guide stands are used for inserting electronic components. Sometimes the X-Y table is moved out of its range of motion, and when transporting the board, the
It is connected to the Y table. In addition, both guide stands are equipped with a conveyor such as a belt conveyor for conveying the substrate in the feeding direction, and the carry-in guide stand is equipped with a pusher for sending the board from the carry-in guide stand to the X-Y table. is provided.

(Problems to be Solved by the Invention) In the case of the above-mentioned conventional device, the substrate is transferred from the X-Y table to the unloading guide table by a pusher, which moves the substrate on the subsequent loading guide table from the X-Y table to the unloading guide table. When sending it onto the Y table, this is done by pushing it from behind with this succeeding board. Usually, a plurality of automatic insertion machines are arranged in series and used depending on the type of electronic component to be inserted. Therefore,
Boards are sent one after another to the next stage insertion machine for insertion of various different parts, but depending on the type of board, there are some insertion machines that do not need to insert parts, so the board is simply sent to the next stage as it is. There are times when you want to.

In response to such demands, the above-mentioned conventional transfer device uses a pusher to feed a new board onto the X-Y table after the insertion work for the subsequent board is completed in the previous stage inserter. Therefore, as long as the insertion work for the subsequent board is not completed, even if the next stage insertion machine is ready to accept,
It cannot be sent to the next stage and must be kept on standby. This is extremely disadvantageous in terms of work efficiency and economy.

(Means for Solving the Problems) According to the present invention, the above problems are solved by a substrate conveying device having the following features. That is,
The substrate conveyance device of the present invention includes a first belt conveyor configured by at least one pair of rotating shafts that are rotatably held and a belt that is directly or indirectly stretched between the rotating shafts. an X-Y table for holding a substrate, which is controlled to move in the X-axis direction and the Y-axis direction with respect to the head means for inserting components into the substrate placed on the belt; and one end of the X-Y table. At least a pair of rotators, which are provided adjacent to the side, are connected to the first belt conveyor during substrate conveyance, are moved outside the movement range of the X-Y table during component insertion work, and are rotatably held. A carry-in guide table having a second belt conveyor constituted by a shaft, a belt directly or indirectly stretched between the rotating shafts, and a drive source; At least a pair of belt conveyors are provided adjacent to the end side, are connected to the first belt conveyor during substrate conveyance, are moved outside the movement range of the X-Y table during component insertion work, and are rotatably held. an unloading guide stand having a third belt conveyor configured by a rotating shaft, a belt directly or indirectly stretched between the rotating shafts, and a drive source; It is characterized by comprising a rotating shaft connecting means for transmitting the rotational force of the rotating shaft of at least one of the second and third belt conveyors to the rotating shaft of the first belt conveyor.

(Function) The substrate transfer means of the X-Y table is drive-coupled with the substrate transfer means of this guide stand when this table is connected to the carry-in guide stand, the carry-out guide stand, or both, and therefore the - The substrate transfer means of the Y table is driven by driving the loading guide stand, the unloading guide stand, or both substrate transfer means, and the substrates on the X-Y table can be moved arbitrarily regardless of the subsequent substrates. It is transported onto the unloading guide table.

The substrate transfer device 1 has an X-Y table 10 in the center.
It has a guide stand 11 for carrying in and a guide stand 12 for carrying out before and after it. The board is sent onto the X-Y table 10 by a board transfer means such as a conveyor provided on the carry-in guide table 11 and, if necessary, a pusher, where electronic components are inserted by the operation of the head means 4. When the work is completed, it is transported to the unloading guide stand 12.

FIG. 1 and FIG. 2 show the above-mentioned substrate transport device of the present invention in detail. The X-Y table 10 is supported so as to be movable in the axial direction on a Y-axis 10a extending perpendicularly to the substrate feeding direction. Y-axis 10a
is an X-axis table 10 supported movably in the axial direction on an X-axis 10b extending in the board feeding direction.
It is fixed on e. Therefore, the X-Y table 10 can be moved horizontally in the X-axis and Y-axis directions with respect to the head means 4, and this movement can be NC-controlled by a conventional drive mechanism and control device.

The X-Y table 10 has two parallel guide frames 10d extending in the board feeding direction, and both guide frames are integrally connected by a connecting rod 10k. Inside each of these guide frames, a substrate transfer means consisting of a belt conveyor 10c is provided. The upper running part of the belt conveyor 10c has a support piece 10 horizontally projecting inward from the guide frame 10d.
f (Fig. 3). The guide frame 10d further has an edge 10 above and parallel to the support piece 10f.
g, thus the belt conveyor 10c
A groove portion 10h for supporting and guiding the side edge portion of the substrate is formed between the upper running portion and the edge portion 10g.

The loading guide table 11 is also the same as the above X-Y table 1.
As in the case of No. 0, it has two parallel guide frames 11a extending in the board feeding direction, and these guide frames are integrally connected by a connecting rod 11b. A substrate transfer means consisting of a belt conveyor 11c is similarly provided inside the guide frame 11a, as well as grooves (not shown) for supporting and guiding the side edges of the substrates. The belt conveyor 11c described above is circularly driven by a belt drive motor 11d provided on the guide stand 11, and the driving force applied to one belt conveyor is transmitted to the other belt conveyor by a drive transmission shaft 11e. A synchronous drive of both belts is provided.

The guide stand 11 has one end connected to the machine frame 13 as shown in the figure.
The piston-cylinder device 14 is configured to be pivotally supported on the piston-cylinder device 14 and to be tilted. X the board
- When transporting to the Y table, the guide stand 11 is placed in the horizontal position actually shown in FIG.
It is brought to a position where it is connected to the table 10, and during the insertion operation, it is tilted to a position shown by an imaginary line out of the horizontal movement range of the X-Y table 10.

When the guide stand 11 is brought to the horizontal position, that is, the connected position, the belt conveyor 1 of the guide stand 11
A means 15 for transmitting the drive of the X-Y table 10 to the belt conveyor 10c is provided between the two, and this means specifically
1c, the drive gear 11g fixed to the shaft 11f rotationally driven by the belt conveyor, the engagement gear 11h held in mesh with this gear, and the guide stand 11 are in a horizontal position. A driven gear 10i on the X-Y table side is provided at a position where it meshes with the engaging gear 11h when the belt conveyor 10c is in the position of the shaft 10j. is fixed to.

As shown in FIG. 3, the drive gear 11g and the engagement gear 11h are supported by a dog-shaped lever 11i that is rotatably supported on a shaft 11f, and this lever is supported by a torsion coil spring 11j. Thus, the engaging gear 11h is biased to be pushed in the direction of the gear 10i. In this case, the rotation range of the lever 11i is restricted by a stopper 11k.
Due to the action of the torsion coil spring 11j, the engaging gear 11h is always maintained in a good state of engagement with the driven gear 10i, and the rotational drive of the driving gear 11g is reliably transmitted to the driven gear 10i.

Since the carry-out guide stand 12 has substantially the same configuration as the carry-in guide stand 11, detailed explanation thereof will be omitted.

The operation of the above-mentioned conveying device according to the present invention is as follows.

The X-Y table 10 has an X-axis 10b and a Y-axis 10a provided on a base 13 and an X-axis table 10e in order to insert electronic components into a board placed thereon.
According to the lowered position of the head means 4, the head means 4 moves horizontally along the lower axis. At this time, the loading/unloading guide stand 11, 1
2 is maintained at a predetermined angle of inclination by means of piston-cylinder devices 14 and 16, with rotating shafts 11e and 12e provided on the base 13 as fulcrums. The belt conveyors 11c and 12c of the guide stands 11 and 12 are in a driving state at this time as well, the substrates on the carry-in guide stand 11 are regulated by the stopper 11m, and the substrates on the guide stand 12 are sent to the subsequent stage. When the insertion of the parts is completed, the X-Y table 10 returns to the reference position, and then the guide stands 11 and 12 are rotated to a horizontal state. At this time, the stopper 11m is released and the engagement gear 11h engages with the driven gear 10i, thereby driving the conveyor belt 10c of the X-Y table 10. Therefore, the substrates on each table move, and the X-Y table 10
An uninserted board is fed onto the top. When an uninserted substrate arrives at a predetermined position on the X-Y table, the guide stands 11 and 12 are lifted to the inclined position again by a signal from a detection means (not shown) that detects this.

In addition, the belt conveyor 11 is installed on the loading guide stand 11.
In addition to c, a pusher may be provided to push the substrate a predetermined distance and move the substrate quickly.

(Effects of the invention) By keeping the guide stands installed at the front and rear of the X-Y table horizontal, the entire system can be used as a simple belt conveyor, so when parts are not inserted, that is, when it is desired to feed boards in a blank manner, Boards can be quickly sent from the preceding insertion machine to the subsequent insertion machine without changing the arrangement of the insertion machines, allowing effective and economical component insertion. Further, the conveyor belt 10c of the X-Y table 10 is connected to the guide table 1 by means of a driving coupling means such as an engagement gear 11h.
Since it is driven by the driving force of the first belt conveyor 11c, it does not require its own driving source, resulting in a simplified configuration and cost reduction.
