Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic insertion machine that automatically inserts circuit components into a printed wiring board, and in particular, an automatic insertion machine that automatically inserts a predetermined mark on a printed wiring board where an insertion error has occurred. The present invention relates to an automatic marker device attached to a vehicle.

[Technical Background of the Invention] As is well known, in recent years, in order to mass produce electronic devices, the work of inserting circuit components into printed wiring boards,
Automation of soldering work, etc. is being actively carried out, and various types of automatic insertion machines and automatic soldering devices are being developed. Among these, the automatic insertion machine is used to insert printed wiring boards 13 that are transported along a pair of rails 11 and 12, as shown in FIG.
is stopped at a predetermined insertion work position, and the insertion head 15, which sequentially feeds out the circuit components 14 according to the insertion order, moves up and down while changing its position, direction, etc.
Various circuit components 14 are automatically inserted in sequence into component insertion through holes 13a formed in the printed wiring board 13.

By the way, as shown in FIG. 7, the above-mentioned automatic insertion machine is capable of handling errors when, for example, the lead leg of the circuit component 14 is not properly inserted into the component insertion hole 13a of the printed wiring board 13, that is, the insertion error occurs. If this occurs, the operation is stopped at that point, and the supervisor then performs the following tasks.

That is, when the operation of the automatic insertion machine is stopped, the supervisor marks the part of the printed wiring board 13 where the insertion error has occurred with marker ink 16 or the like, as shown in FIG.
Give it a 7. Thereafter, the supervisor removes the uninserted circuit component 14 from the printed wiring board 13, attaches paper tape 18 to the edge of the printed wiring board 13 where the insertion error occurred, as shown in FIG. A mark 19 indicating that there has been one insertion error is placed on the Qi 118, and the automatic insertion machine is operated again.

Then, when an insertion error occurs again, the supervisor uses the marker ink 16 to mark the location where the insertion error occurred, and also marks 19' on the paper chip 118, and repeats the same operation every time an insertion error occurs. It is something that is repeated.

[Problems in the background art] However, in the conventional automatic insertion machine as described above, each time an insertion error occurs, the operation is stopped and a mark is manually added. When this occurs, the paper tape 18 must be pasted, which causes a problem that reduces the efficiency of the component insertion work.

In addition, since one supervisor usually monitors multiple automatic insertion machines, for example, if an insertion error occurs in multiple automatic insertion machines, the supervisor will check the last automatic insertion machine. The machine is often stopped for a very long time, and this also causes a decrease in the efficiency of the insertion operation.

[Purpose of the Invention] This invention was made in consideration of the above circumstances, and provides an extremely good automatic insertion machine that can automate the marking work when insertion errors occur and improve the work efficiency of the automatic insertion machine. The purpose of the present invention is to provide an automatic marker device.

[Summary of the Invention] That is, the automatic marker device of the automatic insertion machine according to the present invention detects an insertion error of a circuit component onto a printed wiring board and marks the portion of the printed wiring board where the insertion error has occurred.
and a second automarker means that marks the number of insertion errors on the printed wiring board when all circuit components have been inserted into the printed wiring board. The marking work is automated, and the work efficiency of the automatic insertion machine can be improved.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. That is, in FIG. 1, 20 is an automatic insertion machine main body, and a loading conveyor 21 and an unloading conveyor 22 are installed on both sides thereof. Then, the printed wiring board (not shown) placed on the loading conveyor 21 is conveyed in the direction indicated by the arrow in the figure and stopped on the table 23 of the automatic insertion machine main body 20. z) is inserted.

Here, a point marker mechanism 25 is provided near the insertion head 24. FIG. 2 shows details of this point marker mechanism 25. That is, a pair of frame plates 26 and 27 are fixed to the automatic insertion machine main body 20 so as to face each other. These frame boards 26 and 27 are installed so as to have an inclination of approximately 45 degrees with respect to the surface of the printed wiring board 28. A cylindrical spacer 29.30 is interposed between the flake 18 plates 26.27, and the spacer 29.30
Screws 31 and 32 are loosely inserted inside and fastened to nuts 33 and 34, thereby fixing them substantially in parallel.

Further, a cylinder mechanism 35 is attached to a substantially central portion of the frame plate 26. This cylinder mechanism 35 has the function of automatically moving a piston 36, which is provided along the longitudinal direction of the spacer 29, 30 so as to be removable and removable, in the direction of arrow B when it is detected that a component insertion error has occurred. This is what we do.

The piston 36 is connected to a marker portion 38 via a joint 37. Part 38 of this marker
The marker body 38a is inserted through the frame plate 27 and is movably provided in conjunction with the piston 36, and the inside thereof is filled with ink.The marker body 38a is provided at the tip of the marker body 38a. The felt 38b is impregnated with the ink filled in the felt 38b.

Moreover, the felt 381) is attached to the frame board 27.
A cap 39 is provided to cover the.

The tip of this cap 39 is normally sealed, and when the piston 36 is moved in the direction of arrow B,
It opens by being pressed by the felt 38b.

Further, an air nozzle 40 is attached to the frame plate 26. This air nozzle 4o automatically sprays air onto the printed wiring board 28 when it is detected that a component insertion error has occurred.

In the point marker mechanism 25 configured as described above, when a component insertion error occurs and is automatically detected, first, the operation of the insertion head 24 is stopped and the component insertion work is stopped. Then, the piston 36 is moved in the direction of arrow B by the cylinder mechanism 35, and the felt 38b of the marker part 38 spreads out the tip of the cap 39 and comes into contact with the printed wiring board 28. A point mark is attached to the area where the .

Next, air is sprayed from the air nozzle 40 onto the surface of the printed wiring board 28, and circuit components lying on the printed wiring board 28 without being inserted are blown away. After that, the automatic insertion operation starts again, and if an insertion error occurs again, the mark Ill i? , a mark is placed on the part of the wire board 2B where the insertion error occurred, and after the circuit components are blown away, the automatic insertion work is started again.

The printed wiring board 28 on which all the circuit components have been inserted as shown in FIG. Here, the unloading conveyor 22 is provided with a count marker mechanism 41 and a side marker mechanism 42. Of these, the count marker mechanism 41 functions to automatically stamp a count mark indicating the number of insertion errors on one printed wiring board 28 on that printed wiring board 28. Further, the side marker mechanism 42 has the function of attaching a side mark to one end surface of the printed wiring board 28 where the insertion error has occurred, indicating that the printed wiring board 28 has been inserted incorrectly.

Here, FIG. 3 shows details of the count marker mechanism 41. That is, this count marker mechanism 41 has a support frame plate 43 fixed substantially parallel to the surface of the printed wiring board 28.

A cylinder mechanism 4 is provided in the center of the support frame plate 43.
4 is provided. This cylinder mechanism 44 automatically moves a piston 45, which is provided to be able to move in and out in the vertical direction in the figure, downward in the figure when the printed wiring board 28 reaches a position corresponding to the count marker mechanism 41. It has the effect of causing

The above-mentioned screws] to 45 also include the support frame plate 4.
A movable plate 46 is attached to the movable plate 46, which is set substantially parallel to the movable plate 3.

This movable plate 46 has guide shafts 4 implanted at both ends thereof.
7.48 passes through guide portions 43a and 43b provided at both ends of the support frame plate 43, so that it moves in the vertical direction in the figure in conjunction with the piston 45 while remaining parallel to the support frame plate 43. It is something that is moved.

A plurality of (four in the illustrated case) cylinders 49 to 52 are arranged in parallel on the movable plate 46. These cylinders 49 to 52 have their screws 49a to 5, respectively.
2a independently in the vertical direction in the figure. And each screw l~n 49a~52a,
Stamps 49b to 52b are attached to each of them.

Here, numerical values Ml, r2J, r4J, and r8J are attached to each of the stamps 49b to 52b, respectively, and when the movable plate 46 is lowered downward in the figure by the cylinder mechanism 44, the cylinders 49 to Stamps 49b to 52b lowered downward in the figure by 52
Only the printed wiring board 28 is brought into contact with the printed wiring board 28.

For example, if an insertion error occurs once while parts are being inserted into the printed wiring board 28,
1] is lowered downward in the figure by the action of the cylinder 49. Further, when an insertion error occurs twice, the stamp 49b is raised, and the stamp 50b with the number "2" attached thereon is lowered downward in the figure by the action of the cylinder 50. Furthermore, if an insertion error occurs five times, for example, the stamp 49b with ``1J'' and the stamp 51b with ``4'' attached are lowered in the figure by the action of the cylinders 49 and 51.

In this manner, with each stamp 49b to 52b being lowered by the action of the cylinders 49 to 52 in accordance with the number of insertion errors, the component insertion work for the printed wiring board 28 is completed, and the printed wiring When the plate 28 is conveyed to the unloading conveyor 22 and reaches the position corresponding to the count marker mechanism 41, the movable plate 4 is moved by the action of the cylinder mechanism 44.
6 is lowered downward in the figure, and the stamps 49b to 52b lowered by the cylinders 49 to 52 are brought into contact with the printed wiring board 28, and a count mark indicating the number of insertion errors has occurred is attached to the printed wiring board 28. It is something that will come to be done.

Here, adding the number of insertion errors to the printed wiring board 28 is necessary in order to prevent omissions when the operator later inserts a circuit component into a location where an insertion error occurred. That's true. Furthermore, in the count marker mechanism 41 shown in FIG.
If there are 5 insertion errors, it is considered that there is a problem with the automatic insertion machine itself, so the automatic insertion machine is usually stopped after 3 to 5 insertion errors and an inspection is performed. It is.

On the other hand, FIG. 4 shows details of the side marker mechanism 42. That is, the cylinder mechanism 53 is fixed to the base body 22a of the unloading conveyor 22. This cylinder mechanism 53 moves the piston 54, which is provided so as to be freely removable and removable in the vertical direction in the figure, in a state in which an insertion error has been detected by the point marker mechanism 25, that is, in a state in which the point mark has been attached. direction.

A stamper 56 is attached to the piston 54 via a pedestal 55. When the piston 54 is moved upward in the figure by the cylinder mechanism 53, the stamper 56 is inserted into the printed wiring board 2, as shown by the dashed line in the figure.
8. The position is opposite to the end surface of 8. Therefore, when the printed wiring board 28 in which an insertion error has occurred in even one place is conveyed by the unloading conveyor 22, its end face comes into contact with the stamper 56, and the printed wiring board 28 in which the insertion error has occurred is brought into contact with the stamper 56. As shown in FIG. 5 for plate 28,
A side mark 57 is attached.

Adding the side mark 57 to the end face of the printed wiring board 28 where the insertion error occurred in this way is useful when the printed wiring boards 28 where the insertion error has occurred are stacked and stored in a magazine, etc., when the insertion error has occurred. The work name of the wiring board 28 can be easily identified when viewed from the outside.

Therefore, according to the configuration of the above embodiment, the point marker mechanism 25 detects an insertion error into the printed wiring board 28, automatically places a point mark on the part where the insertion error has occurred, and the count marker mechanism 41 A count mark indicating the number of insertion errors is automatically attached, and a side mark 57 is automatically attached using the side marker mechanism 42 to indicate that the printed wiring board 28 has been inserted incorrectly. The operation is stopped every time an insertion error occurs, and the mark 17.1 is manually added.
9, and there is no need to attach a paper guide 718 when an insertion error occurs for the first time.
This makes it possible to improve the efficiency of component insertion work.

In addition, even if an insertion error occurs in multiple automatic insertion machines at almost the same time, there is no need for the supervisor to turn each automatic insertion machine one after another, so the automatic insertion machines will stop operating for a long time. In this respect, the efficiency of the insertion work can be improved.

FIG. 6 shows a modification of the point marker mechanism 25. That is, ink is automatically supplied to the marker body 38a of the marker portion 38 from the ink storage portion 58 via the pump 59, contributing to further automation. It is.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] Therefore, as described in detail above, according to the present invention, it is possible to automate the marking work when an insertion error occurs, and to improve the work efficiency of the automatic insertion machine. A marker device can be provided.
