positions the board 8 at the insertion position. The electronic components 7 are sorted by type and held in the component supply section 1. When the component supply section 1 moves to a predetermined position in order to supply the electronic components 7 in a predetermined order, the component relay section 2 grabs the electronic components 7 and transfers them to the insertion head section 3 . The insertion head section 3 inserts the electronic component 7 into a predetermined position on the board 8 . The anvil portion 5 fixes the lead wire of the inserted electronic component and also determines whether the insertion is successful or not. The above operation is performed for each electronic component.

[0005] When an insertion error occurs, the insertion error is detected by the anvil portion 5 and the electronic component insertion machine is temporarily stopped.

[0006] The operator manually removes the incorrectly inserted part.
After that, operate the restart switch to perform corrective insertion, or leave it as is and insert the remaining electronic components 7.
The boards 8 were pooled in a separate stocker from the normally inserted boards 8, and reworked all at once.

[0007]

[Problems to be Solved by the Invention] Conventionally, as mentioned above, when an electronic component insertion machine makes an insertion error, the electronic component insertion machine is stopped each time an insertion error occurs, and the operator manually inserts the component. There is a problem in that it is necessary to remove the faulty electronic component and perform an operation to restore the normal state. In addition, there is the problem that highly efficient automated production is impossible because night work requires periodic inspection, and there is also the problem that manual rework is less productive than automatic insertion. there were.

An object of the present invention is to solve these problems and provide an auto-recovery method that can handle insertion errors in an electronic component inserter without any human intervention.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the automatic recovery method for an electronic component insertion machine of the present invention provides an automatic recovery method for an electronic component insertion machine in which an electronic component insertion machine is attached to an anvil portion for fixing lead wires of an electronic component when inserting an electronic component. An insertion error detection process in which an insertion error is detected and the insertion work of the electronic component insertion machine is temporarily stopped, and an insertion error detection process in which a recognition camera is relatively moved to recognize the insertion status of the electronic component into the insertion hole where the insertion error occurred.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the auto-recovery method for an electronic component insertion machine according to the present invention will be described with reference to FIGS. 1 to 7.

In FIGS. 1 and 2, electronic components 7 are sorted by type and held in a component supply section 1. The component supply section 1 supplies electronic components 7 to the component relay section 2 while moving in a straight line. The component relay section 2 is fixed and relays the electronic component 7 from the component supply section 1 to the insertion head section 3. The insertion head section 3 inserts the electronic component 7 received from the component relay section 2 into the board 8. The anvil portion 5 bends and fixes the lead wire of the inserted electronic component, and also determines whether the insertion is successful or not. The XY table 6 holds the substrate 8 and is movable in a plane. The recognition camera 10 recognizes the state of insertion of the electronic component into the electronic component insertion hole in which the incorrectly inserted electronic component was inserted, and confirms the position of the insertion hole after the incorrectly inserted electronic component is removed. The monitor 11 displays the recognition results of the recognition camera 10. The extraction robot unit 4 removes the fixation of the lead wire at a extraction position 12 (not shown) and extracts the incorrectly inserted electronic component. The operation panel 13 performs operations such as starting and stopping each part of the electronic component insertion machine, and displays the operating status of each part.

During implementation, the NC controller 15 controls the entire electronic component insertion machine. The board 7 is connected to the loader 14
is carried into the XY table 6 by the unloader 16, and carried out from the XY table 6 by the unloader 16. XY table 6
positions the board 8 at the insertion position. The parts supply section 1
When moving to a predetermined position in order to supply the electronic components 7 in a predetermined order, the component relay section 2 grabs the electronic components 7 and transfers them to the insertion head section 3 . The insertion head section 3 inserts the electronic component 7 into a predetermined position on the board 8 . The anvil portion 5 bends and fixes the lead wire of the inserted electronic component, and also determines whether the insertion is successful or not. The above operation is performed for each electronic component.

FIGS. 3 to 6 are diagrams schematically showing the process from immediately after the electronic component insertion machine makes an insertion error until the electronic component insertion machine returns to normal operation after removing the erroneously inserted electronic component 9.

In FIG. 3, in the insertion error detection step, the anvil portion 5 is caused to detect an insertion error and the electronic component insertion machine is temporarily stopped. Next, in an insertion error recognition step, the XY table 6 is moved in a plane so that the incorrectly inserted electronic component 9 is located below the recognition camera 10. A recognition camera 10 is made to recognize the state of insertion of an electronic component into an insertion hole where an insertion error has occurred, and the recognition result is displayed on a monitor 11.

FIG. 7 shows an example of the display on the monitor 11.
1-1 indicates the left leg remaining, 11-2 indicates the right leg remaining, and 11-3 indicates both legs remaining, as well as positional deviation.

In FIG. 4, in the removal process, the XY table 6 is moved in a plane based on the recognition result, and the incorrectly inserted electronic component 9 is moved to be below the extraction robot 4 at the extraction position 12. The pulling robot 4 is lowered to grab the electronic component 9 that has been mounted incorrectly, and to unfix the incorrectly inserted lead wire.

In FIG. 5, the pulling robot 4 grasps and lifts the misinserted electronic component 9, and removes the misinserted electronic component 9.
is pulled out from the board 8. In this case, the extraction robot 4 performs extraction focusing on the remaining leg based on the recognition result of the insertion status of the lead wire of the electronic component into the insertion hole where the insertion error occurred. Pull out one leg first, then the other leg. The XY table 6 is moved in a plane to position the insertion hole after the incorrectly inserted electronic component 9 has been pulled out under the recognition camera 10. To the recognition camera 10,
A state in which the incorrectly inserted electronic component 9 is completely pulled out, that is, FIG. 7
The state of 11-4 and the position of this insertion hole are confirmed, and the results are displayed on the monitor 11. During this time, the component supply section 1 supplies the electronic component 7 of the same type as the incorrectly inserted electronic component 9 to the component relay section 2, and the component relay section 2 relays this electronic component 7 to the insertion head section 3. In FIG. 6, based on the result of confirming the position of the insertion hole, the insertion head part 3 is moved in plane to the XY table 6, and the insertion head 3
position it below.

The insertion head section 3 is lowered to insert the electronic component 7, and the electronic component insertion machine is returned to normal operation.

In this case, if an insertion error occurs again, reinsertion is repeated in the same manner as above, but if the insertion error is repeated three times, insertion at that position is stopped and the next electronic component is inserted. After the board 8 is moved and the prescribed insertion is completed, the board 8 is stored in a separate location from the normal board 8.

[0027] In this way, even if an insertion error occurs, the electronic component insertion machine can automatically remove the incorrectly inserted electronic component 9 and return to normal operation. If the insertion is repeated, the insertion into that position is stopped and the next normal operation is performed, thereby enabling unmanned operation at night.

[0028] The present invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, this example concerns two-legged resistors and capacitors, but many-legged DIP and SI
It can be applied to various insertion machines including IC parts such as P.

[0029]

[Effects of the Invention] According to the automatic recovery method for an electronic component inserter of the present invention, even if an electronic component inserter makes an insertion error, the electronic component inserter only temporarily stops the insertion operation and automatically removes the incorrectly inserted electronic component. Since it can be reinserted and restored to normal operation, the time required for correction work, which would have been done manually with conventional technology, is shortened, operating rates and productivity are improved, and unattended operation, which was previously not possible, is achieved. This has the effect of making driving possible.
