Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic electronic component insertion device that prevents insertion of foreign items onto a board.

<Prior art> As a conventional automatic insertion device for electronic components, the one shown in FIGS.
(See Publication No. 67400).

That is, an inserter 2 serving as a transfer/insertion means is fixed on a table 1 having a carrier mounting section 1a and a substrate mounting section 1b. Then, the electronic component A is clamped by the chuck 4 at the tip of the arm 3 of the insertion machine 2 from the carrier 5 of the carrier mounting section 1a selected according to a component insertion order predetermined by a control device (not shown), and then The substrate B is transferred to a predetermined position on the substrate 1b and inserted automatically.

<Problems to be Solved by the Invention> However, in such a conventional automatic electronic component insertion device, the arm 3 of the insertion m2 is connected to the selected and specified carrier mounting portion 1a and a predetermined position on the board B. Since the electronic components in the carrier 5 of the carrier mounting section 1a are inserted into a predetermined position on the board B without directly identifying the electronic components in the carrier 5 of the carrier mounting section 1a, the carrier 5 may be inserted into the carrier mounting section due to an operator's error. When a carrier containing different electronic components is placed,
If a foreign item is inserted onto the board B, or if insertion is not possible, parts or the board may be damaged.

Further, electronic components A include, for example, aluminum electrolytic capacitors, tantalum capacitors, and diodes.

Some products, such as module resistors, have positive and negative terminals, and it is necessary to insert the proper polarity terminals into the specified positions on the board B. However, in the process of aligning and storing them in the carrier 5, If it is stored in the opposite direction, it will be inserted onto the board B with the polarity direction reversed.

The present invention has been made in view of the problems of the conventional technology, and an object of the present invention is to provide an automatic electronic component insertion device that can prevent incorrect insertion of electronic components onto a board.

<Means for solving the problem> For this reason, a type display section is provided for each carrier to display the stored electronic components, and the type of carrier to be placed on the selected carrier placement section before holding the electronic component is provided. A placement location abnormality determination means for determining an abnormality in a carrier placement location by detecting a display part, and a position where a polarity discrimination mark formed on a polarized electronic component is abnormal at a predetermined position before insertion of the component. polarity direction abnormality determination means for determining that the polarity direction is abnormal.

Since the above configuration is adopted, even if a carrier other than the official carrier is installed in the carrier mounting section by mistake, or if the carrier is stored with the polarity reversed, incorrect installation or storage will not occur. Since it can be detected, electronic components will not be incorrectly inserted onto the board.

<Example> FIG. 1 shows an example according to the present invention. Note that elements similar to those in the conventional example are designated by the same reference numerals, and description thereof will be omitted.

A type display section 10 is provided at the bottom of the carrier 5. The type display section 10 is constituted by, for example, a bar code or a bit hole, and displays the electronic component housed in the carrier 5.

Further, the carrier placement section 1a is provided with an optical sensor 1 that detects the type display section 10 of the carrier 5 placed here.

Furthermore, an optical sensor 12 is provided near the chuck 4 of the insertion machine 2 to detect a polarity discrimination mark a attached to the electronic component A held by the clamp 4. Note that the optical sensor 12 is
The inserter 2 may be stopped at a predetermined position with the electronic component A being held between the chuck 4, and the inserter 2 may be provided at a position opposite to the polarity discrimination mark a of the electronic component A during normal operation.

The outputs of the optical sensors 11 and 12 are input to a control device 13, and a control signal is output from the control device 13 to a buzzer 14 and a motor 15 that drives the arm 3 and chuck 4 of the insertion m2.

The control device 13 includes a microcomputer, and functions as a placement location abnormality determination means and a polarity direction abnormality determination means are stored in the form of software.

The contents of the software will be explained according to the flowchart shown in FIG.

In step 1 (hereinafter referred to as Sl in the figure), the type of electronic component A to be inserted is read in accordance with a predetermined component insertion order.

In step 2, the type display section 1 of the carrier placed on the carrier placement section 1a selected in advance according to the order of component insertion.
0 is read by the optical sensor 11 and the type of electronic component is determined.

In step 3, it is determined whether the electronic component in the carrier 5 is a regular electronic component A or not. If the electronic component in the carrier is not genuine due to incorrect installation of the carrier, the process proceeds to step 4, and if it is a genuine electronic component, the process proceeds to step 6. Here, steps 1 to 3 are as follows:
This constitutes a placement location abnormality determination means.

In step 4, a control signal is issued to the buzzer 14 to activate the buzzer 14.

In step 5, a drive stop signal is issued to the drive motor 15 of the insertion machine 2.

In step 6, the electronic component A held by the chuck 4 is
The polarity discrimination mark a is read as the output of the optical sensor 12.

In step 7, the polarity direction is determined based on whether there is a polarity determination mark on the side where the optical sensor 12 is provided.

In step 8, it is determined whether the polar direction is normal. Here, steps 7 and 8 constitute polarity direction abnormality determination means.

In step 9, when the polarity direction is not normal, a control signal is issued to the motor 15 to stop the normal insertion operation.

In step 10, a control signal is issued to the motor 15 to cause the electronic component held by the chuck 4 to be ejected.

Thereafter, the inserter 2 is returned to the carrier mounting portion 1a, the electronic component A is again clamped by the chuck 4, and the electronic component A is transferred and inserted onto the substrate through the steps from step 6 onwards.

Since the control is performed as described above, even if the carrier 5 is incorrectly installed or the electronic component A is stored in the carrier 5 with the polarity reversed, the abnormality can be detected before inserting it onto the board B. Therefore, incorrect insertion onto the board B can be prevented.

<Effects of the Invention> As described above, according to the present invention, the type display section provided on the carrier is detected to determine an abnormality in the carrier placement location, and an abnormality in the polarity direction of the electronic component is determined. This makes it possible to prevent incorrect insertion of electronic components.
