Description

[Detailed Description of the Invention] [Summary] In an automatic IC insertion device, it is possible to electrically connect an IC to be inserted to an external test circuit through a contact provided on an IC holder. Incorrect insertion can be completely prevented by testing the product before inserting it into the predetermined position.

[Industrial application field]

The present invention relates to the control of a device that inserts an ICf of the -fc1 class designated at a predetermined position on a printed circuit board, and prevents incorrect insertion of a different type of IC due to reasons such as being incorrectly loaded in the device in advance. related to control.

[Conventional technology]

Conventionally, as an automatic insertion device for ICs onto a printed board, for example, a plurality of IC storage cylinders are arranged so as to be movable, and on the other hand, the printed board is held and placed on the plane of the printed board. Using a device having a table that can be moved vertically and horizontally, ICs of different types (standards) are placed in the IC storage tubes in advance for each IC storage tube.
After loading a plurality of IC storage tubes, select the IC storage tube loaded with the required IC and move the printed board to determine the position, and then access the IC storage tube to insert the desired IC. There is a structure to be inserted.

The operation of such an automatic IC insertion device is controlled using information used in designing the printed board pattern. (
(This information includes information regarding the logical connection of elements and IC mounting information.) [Problems to be solved by the invention] In the conventional automatic IC insertion device described above, the control is based on the printed board. Since this is performed by a program using pattern design information, its operation is highly reliable.

However, if an IC of a different standard is mistakenly loaded in the IC storage case, it will not be possible to determine this, and the IC will be inserted into the printed board as is.

Usually, ICs are often exactly the same in terms of external structural dimensions, etc., so it is easy to make such a mistake.

Furthermore, even if the IC is not incorrect, the loaded IC may be defective.

In such cases, it is extremely difficult to detect mistakes or defects among the large number of IC's inserted into the printed circuit board, and once the terminals have been soldered, it is difficult to attach and detach them, resulting in a lot of work. There was a problem in that it required a lot of work time.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a means for preventing incorrect IC insertion or defective IC insertion in an IC automatic insertion device.

[Means for solving problems]

According to the present invention, this purpose is to automatically insert a designated type of IC into a predetermined position on a printed board based on given information, as described in the claims. The device is characterized in that the IC holder is provided with a contact that can contact the terminal of the IC to obtain an electrical connection, and that part or all of the internal circuit of the IC is tested through the contact when the IC is inserted. This is achieved by a method to prevent incorrect IC insertion.

FIG. 2 is a diagram illustrating in more detail the structure of the IC housing cylinder and arm shown in FIG. 1.

11 is the same as in Fig. 1, and 3 is the IC housing cylinder 12 is the IC
, 13 represent contacts.

This will be explained below using FIGS. 1 and 2.

As shown in FIG. 2, a plurality of IC storage cylinders 31 to 34 each store a plurality of l012.

Further, it is driven by the drive unit 8 to select a designated IC storage cylinder and hold it at a predetermined position.

The printed board holder 2 holds the printed board 1 and is driven by the drive unit 6 and can move in the direction of the arrow indicated by the person in the figure.

The IC holder (arm) 4 is driven by the drive unit 7,
It can move in a direction perpendicular to the printed board holder 2.

The processor 9 controls which IC housing tube is positioned at which location on the printed board. That is, the processor 9 reads the "IC mounting information" from the "printed board design information (PTM) J" stored in the file 10, and based on this, transmits information regarding the movement direction and movement amount to each drive unit. give. Then, by operating each driving section in accordance with this, the arm 4 and the IC storage cylinder that abuts the body are positioned at a predetermined position on the shiblint plate 1. (In Figure 1, IC storage cylinder 3 is selected and 11
This indicates that the IC is mounted in the position indicated by . ) When inserting the IC, after such positioning,
The IC storage cylinder is pushed down until its lower edge touches the arm 4, and the 1012 stored therein is further pushed down from the top, and the lowermost 1012 is inserted into the arm 4.

The terminal of the IC inserted into the arm 4 is pressed into contact with the contactor 13 to maintain an electrically connected state.

The contact 13 is led to the processor 9 by a connecting line 15.

The processor 9 supplies power to the IC held in the arm 4 via the connection line 15, and the logical operation of the IC is
Check whether the IC is normal to be mounted in that position.
This is checked by comparing it with the "information related to the logical connection of elements" of the corresponding IC included in the "printed board design information" in the file 10.

If it is determined that it is normal, the arm 4 approaches the printed board IK and inserts the held IC into a predetermined position. If the comparison results do not match and it is determined that an IC of a different standard is used or is a defective product, the operation is stopped, an alarm is issued, and the device waits for instructions from the operator. Alternatively, after the IC in the arm 4 is ejected, the next IC in the IC storage cylinder is inserted into the arm 4 and the test is performed again.

〔Effect of the invention〕

As explained above in detail, according to the method of the present invention,
In equipment that automatically inserts ICs into printed circuit boards, if an IC of a different standard is mistakenly loaded into the IC storage cylinder or a defective IC is present, it can be easily detected and the IC can be easily detected. It is possible to take corresponding measures before inserting the IC, and the loss of man-hours during manufacturing can be reduced, which is highly effective.
