Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic electronic component insertion machine, and particularly to an electronic component automatic insertion machine that can correct the insertion position for each electronic component to be inserted. When an electronic component insertion error occurs when inserting an electronic component into a printed circuit board, the automatic electronic component insertion machine automatically repeats the insertion operation according to the instructions of one operator, and the electronic component is the cause of the insertion error. It is effective when inserted into a printed board at certain times.

However, if the mounting hole position of the electronic component on the printed board is misaligned with the pre-specified mounting hole position of the electronic component, in other words, if the cause is on the printed board, give up on inserting the electronic component and install it by hand. (Problems to be Solved by the Invention) The problems in the conventional technology which the present invention attempts to solve are as described above, where the mounting position of the electronic component specified in advance and the mounting position of the printed board are misaligned. Since it is not possible to insert electronic components while the machine is in use, I had to remove the printed circuit board from the automatic insertion machine and then insert the electronic components by hand.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automatic electronic component insertion machine that solves the above-mentioned drawbacks.

(Means for Solving the Problems) The automatic electronic component insertion machine of the present invention is an automatic electronic component insertion machine that inserts and attaches electronic components to a printed board. a component disposal means for removing and discarding the electronic component if the insertion result is not normal; an insertion hole position measuring means for measuring the position of the insertion hole of the electronic component; and an insertion hole position measuring means for storing the insertion hole position specified in advance, and a value measured by the insertion hole position measuring means for the insertion hole position of the electronic component and a value specified in advance. and a data processing means that compares the value of the insertion hole with the value of the insertion hole, calculates the amount of deviation, and issues the instruction to insert the electronic component again at the insertion hole position where the value of 7 has been corrected.

(Example) Next, the present invention will be described in detail with reference to drawings showing examples. Fig. 1 is a flowchart showing the configuration when an embodiment of the present invention is applied to an automatic electronic component mounting device, Fig. 2 is a flowchart showing the operation of an embodiment of the invention, and Fig. 1
FIG. 3 is an external view of the electronic component mounting section shown in the figure.

First, an outline of an embodiment of the present invention will be explained.

In automatically inserting electronic components into a printed board, the present invention has the following features:
If the results are not normal, the electronic component is removed and discarded, and an electronic component of the same standard is inserted. If the automatic insertion result does not become normal even if you repeat the same method for all cases.

The hole position determined in advance when designing the printed board is compared with the hole position of the printed board into which the electronic component will be inserted, the difference is calculated by the data processing means, the insertion hole position is corrected based on the difference, and then the electronic component is inserted. Reinsert the part. Therefore,
Since there is a correction function even if there is a misalignment in drilling holes in the printed board, automatic insertion is possible, which eliminates the manual work of inserting electronic components.

Next, a non-inventive embodiment will be described, focusing on its configuration and operation. Figures 1 and 3. Runi Kinen.

This embodiment is equipped with an electronic component mounting section 1 and a data processing section 2.
3, a component mounting handler 14, a printed board post-processing handler 15, a component tray 16, a component mounting handler 17, and an insertion error determination section 18.

In the movable tray 20 that has received the pudding from the pre-work tray 19, pretreatment of the printed board (for example, preliminary soldering of the printed board) is carried out at pre-specified locations.

Next, the component mounting handler 17 takes out the corresponding electronic component from the component tray 16, inserts the electronic component into the printed board on the moving tray 20, and inserts it into -5 attached to the component loading handler 17. A mistake determination unit 18 (for example, a method in which a force is applied to the base of the electronic component in parallel with the printed board to test whether or not it can be removed) determines whether the component insertion situation is normal or abnormal. If the result is normal, the component mounting handler 14 bends the terminals of the electronic component.

Subsequently, a printed board post-processing handler performs soldering, moisture-proofing, etc., and stores the printed board in the finished tray 21.

Here, if the result determined by the insertion error determination unit 18 is abnormal, the electronic component determined to be abnormal is removed by the component disposal means 12 (for example, the part is pulled out and placed in a disposal box) and discarded. . Thereafter, the component mounting handler 17 takes out the electronic component from the component tray 16 and inserts the electronic component into the printed board on the moving tray 20.

Then, the insertion error determination unit 18 again determines whether the insertion error has occurred, and if the result is normal, the component mounting handler 14 performs the following operations from bending the terminal of the electronic component as described above. If the judgment by the insertion error judgment section 18 is abnormal again, the electronic component is discarded by the component disposal means 12, and the above-mentioned process is repeated.

The number of repetitions is a predetermined number (for example, 2 to 3
If the insertion error determining section 18 makes a determination that the electronic component is abnormal even if the insertion error determining section 18 has reached the number 1, the electronic component is discarded according to the operation of the component discarding means 12, and the position of the insertion hole is measured by the insertion hole position measuring means 11. Next, the difference between the measured value and the designed value is calculated, and the electronic component is inserted by the component mounting handler 17 according to the component insertion hole position corrected by the calculated value.

Note that instructions for these operations, calculation of positions based on measured values, and the like are controlled by a program stored in the data processing unit 2 in advance.

Next, the configuration and operation of the data processing section 2 will be explained with reference to FIGS. 1 and 2.

At the same time, the number of insertion errors at the same location is set to a predetermined number N (for example, N = 2 to 3).
) When the electronic component is small (step, pu■), indicate the name and insertion position of the electronic component and insert the electronic component (step, pu■).
) is 01. When the number of abnormal insertions is N or more (step ■), instruct the measurement of the insertion hole position (step, gu ■),
Compare the result with the pre-memorized insertion position to calculate the amount of deviation (Step 2), correct the pre-memorized insertion position according to the amount (Step 0), and select the name of the electronic component and the insertion position. Instruct the electronic component to be pushed in by specifying the position (Step 2) 0 Repeat this method until the electronic component mounting is completed.

Most of the handlers in this embodiment described above are designed to perform a single task, but if the same handler is used to perform a variety of tasks, the number of handlers will be small, and the equipment It is also possible to make the moving parts of the machine smaller.

(Effects of the Invention) As explained above in detail, the present invention measures the electronic component mounting hole position of the printed board when the electronic component mounting hole position of the glint board is deviated from a predetermined value. The mounting position of the electronic component can then be corrected to match the result and the electronic component can be inserted into the printed circuit board, so even if the mounting position of the electronic component is misaligned with the designed position, the electronic component will be automatically inserted. It has the advantage of being able to be inserted into printed boards.
