Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auto-insertion device that automatically corrects a component insertion error in a component insertion machine such as an electronic component automatic insertion machine that automatically inserts an electronic component into a printed circuit board. The present invention relates to a recovery device and an auto recovery method.

2. Description of the Related Art A conventional component insertion mechanism of an automatic electronic component insertion machine will be described with reference to FIGS. 1 and 2. FIG.

1 and 2, 1 is a component supply unit, 2 is a component relay unit, 3 is an insertion head unit, 5 is an anvil unit, and 6 is X-
It is a Y table.

First, electronic components are sorted by type and stored in a component supply unit. The component supply unit 1 linearly moves on a plane to a position where the component relay unit 2 can grasp a component of a predetermined type. The component relay unit 2 grasps one component from the component supply unit 1 and transfers it to the insertion head unit 3. On the other hand, the printed circuit board is moved to the position of the insertion head unit 3 by the XY table 6, and the parts determined by the vertical movement of the insertion head unit 3 are inserted into the determined positions of the printed circuit board. An anvil part 5 arranged below detects whether the insertion is normal or incorrect. Such an operation is repeated for each part.

When an insertion error is detected by the anvil unit 5, it is common practice to stop the operation of the device, remove the insertion error component by hand, and then operate a restart switch to return to normal operation. Alternatively, the insertion error component is left as it is, and after inserting the remaining components, they are pooled in a place different from a normal printed circuit board, and are collectively corrected.

Problems to be Solved by the Invention As in the conventional example described above, when the device is stopped and the operator manually removes or repairs parts, every time an insertion error occurs, a worker near the device takes time to return to normal. And at night, they had to look around regularly, which was a problem for full automation. In addition, there is a problem that productivity is lower in manual correction than in automatic insertion.

Means for Solving the Problems The present invention is intended to solve such a problem, and an insertion head section for inserting a component into a predetermined position of a board, a detecting means for detecting an inserted state, A withdrawal head that removes the component, a transport unit that transports the substrate to a predetermined position with respect to the insertion head unit and the withdrawal head unit, and when the component detection error is detected by the detection unit, the withdrawal head The transfer means is operated to position the part at the part insertion error part of the substrate, and the extraction head part is operated to remove the insertion error part, while the insertion head part is newly inserted during the operation of the extraction head part. Operating the transfer means so as to position the insertion head portion at a component insertion error position of the substrate, and operate the insertion head portion. And control means for controlling a new component to be inserted into a component insertion error portion of the board. Further, in addition to the above-described configuration, the present invention stores an insertion error when an insertion error at the same location is performed a specified number of times or more, inserts a part of the board other than the insertion error location, and stores the insertion error. The separated substrate is stored separately in another place.

It is preferable to use an anvil part as shown in the embodiment as the detection means. In general, an XY table that moves a substrate on a horizontal plane (XY directions) with the substrate placed at a predetermined position is used as the transfer means, and the insertion head section and the extraction head section have a fixed structure. Conversely, the substrate may have a fixed structure, and the insertion head portion and the withdrawal head portion may have a movable structure using a transporting means.

An NC controller or the like can be used as the control means.

According to the present invention, when a component insertion error is detected by the detecting means, the insertion head is retracted, the extraction head faces the component insertion error, and the insertion error is removed. , And a new part is inserted again to face the above-mentioned portion, so that insertion recovery can be performed efficiently without losing time.

Embodiment An electronic component automatic insertion machine according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

This type of inserter is used exclusively for components that have many leads arranged in two rows, such as integrated circuits (generally referred to as DIP components).

This electronic component automatic insertion machine includes a loader 12, which is a path for inserting a printed circuit board before parts are inserted, and an X-Y, which fixes the printed circuit board and moves in a XY direction on a plane according to a command of the NC controller 11 to determine an insertion position. Y table 6, component supply unit 1, which stores components for insertion by type, component relay unit 2 that grabs a component from component supply unit 1 and passes it to insertion head unit 3, and inserts a component into a printed circuit board The head unit 3 is located below the insertion head unit 3 and the insertion head unit 3
In conjunction with this, the lead wire is bent and temporarily fixed to the printed circuit board, and an anvil part 5 for detecting an insertion error, a pull-out head part 4 for removing an incorrectly inserted part, an unloader 13, which is a delivery path of the printed circuit board after component insertion is completed, It comprises an XY table 6, an NC controller 11 that controls the operation of each device, a main operation panel 14 that performs operations such as starting and stopping each device and an operation status display, and a sub operation panel 15, and the like. I have.

The printed circuit board is loaded on the XY table 6 by the loader 12.
The XY table 6 is moved upward, fixed on the table 6, and positioned by the movement of the XY table 6. On the other hand, the component supply unit 1
And an insertion head unit 3 receiving a component from the component relay unit 2
Inserts the received component onto the printed circuit board, and when the component insertion is completed for a predetermined amount, the printed circuit board is sent out by the unloader 13.

The operation of this device when an insertion error occurs is as follows. FIG. 3 to FIG. 6 are diagrams schematically showing a state from immediately after the insertion head unit 3 makes an insertion error until the insertion error part is removed and the operation returns to the normal operation.

As shown in FIG. 3, when the insertion head unit 3 makes an insertion error and the anvil unit 5 detects this, the "INSERT ERROR" lamp of the main operation panel 14 is turned on, and at the same time, as shown in FIG. The XY table 6 moves the printed circuit board 7 on which the insertion error component 8 is mounted so that the insertion error component 8 is located below the pull-out head 4. Then, the pull-out head part 4 descends and grasps the mis-insertion part 8. Next, as shown in FIG. 5, the pull-out head 4 is raised while holding the mis-insertion component 8, and
On the other hand, the insertion head unit 3 receives the new component 10 from the component relay unit 2. That is, as shown in FIG.
During the operation in which the extraction head unit 4 is extracting the insertion error component 8, the insertion head unit 3 holds the new component 10. Subsequently, as shown in FIG. 6, the XY table 6 moves the printed circuit board 7 to a position below the insertion head section 3 and performs positioning so as to be at a predetermined component insertion position.
When the insertion position is determined, the insertion head 3 descends, inserts a new component 10 into the printed circuit board 7, and returns to normal operation.
If the new component 10 also has an insertion error, the extraction of the insertion error component and the reinsertion of the new component are repeated. If re-insertion is repeated three times or more in the same place, the insertion of the place is stopped, and the parts are inserted in the next predetermined place. Is stored in a separate place. In this way, the removal head part 4 automatically removes the incorrectly inserted part and returns to the normal operation. If the insertion error is repeated three or more times at the same place, the insertion into the place is stopped and the process proceeds to the next step. This enabled nighttime unmanned exercise.

In some cases, a recognition camera is used as an auxiliary means for detecting an insertion error and determining the situation of an insertion error, thereby increasing the insertion accuracy and the extraction accuracy of the insertion error component.

FIG. 7 shows an NC controller 11 for performing the above correction operation.
Is shown. In FIG. 7, an insertion error is detected every time a component is inserted. However, if an insertion error occurs, the insertion error component is removed by the extraction head part, and it is determined whether the insertion error has occurred three or more times in the same place. And 3
If it is less than the number of times, reinsert it at the place where you missed. However, if the same location is repeated three or more times, it is memorized that there is an insertion error, then the insertion at that location is stopped, another location is inserted, and it is determined whether or not there has been an insertion error when all the insertion steps have been completed. The printed circuit board having the insertion error is stored separately in another place. The number of repeated determinations of insertion errors at the same location is not limited to three, and can be set arbitrarily.

Further, the present embodiment relates to a dedicated DIP machine,
The present invention can be applied to various insertion machines from two-legged resistors, capacitors, and diodes to various components such as a multi-legged resistor network and SIP.

Advantageous Effects of the Invention The present invention can automatically remove an incorrectly inserted part and immediately insert a new part without stopping the apparatus as described above, thereby reducing the time required for correction and increasing productivity due to an increase in travel time. Along with the improvement of the vehicle, enabling unmanned driving during the day and night.
