Abstract

PURPOSE:To control erroneous mounting of parts and remainder of parts with a mounting machine employing different parts cassettes which is not practicable by conventional method where memories are provided to parts cassettes, and enable the control on kinds of parts and the remainder of parts. CONSTITUTION:Information about parts name, parts characteristics, remainder of parts, etc., is recorded in bar codes 2 provided to the bottom of a carrier tape 1, and by reading such information into a mounting machine, erroneous mounting of parts caused by mistakes in attaching the parts is prevented while precautions are given for running-out of stored parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply tape for accommodating components such as electronic components and mechanical components.

[0002]

2. Description of the Related Art A conventional component supply tape and an example of management of a component name, a component characteristic value and a remaining component number using the same will be described.

FIG. 4 is a perspective view showing the most common component supply tape. In the figure, 9 is a cover tape, 1 is a carrier tape, and a chip component 11 is sealed in a component sealing hole 10.

FIG. 5 shows a parts cassette provided with a recording unit for storing a part name, a part characteristic value, and the number of parts held, so that mis-mounting of parts and management of the number of remaining parts can be performed. Before setting the parts cassette 4 in the parts supply section 7 of the mounting machine 14, the operator displays a code on the parts name, initial holding number, resistance value, capacitance, etc. provided on the reel 3 of the tape-shaped parts assembly. The bar code 12 is read by the bar code reader into the recording unit 13. The data recorded in the recording unit 13 is sent to the mounting machine through the reading / writing means 15 in the main body of the mounting machine 14. Further, during the component mounting work, the swing lever 16 swings every time a component is picked up to output a pick-up detection signal, and each time the component holding number recorded in the recording unit 13 is subtracted by one. Rewrite.

By the above method, erroneous mounting of parts and management of the remaining number of parts can be managed for each cassette.

[0006]

However, in the above configuration, a device for storing the type of parts and the remaining number of parts is required for each individual parts cassette. If the parts cassettes are not compatible with each other, it is not possible to manage the information such as the type of parts and the remaining number of parts stored in the recording unit. Further, since the information is managed for each parts cassette, the remaining number of parts cannot be managed when the parts in the parts cassette are replaced in the middle.

The present invention solves the above problem and manages information on the type of component storage tape and the number of remaining components for each tape.

[0008]

In order to solve the above-mentioned problems, the present invention provides a bottom surface of a carrier tape with symbols indicating the types of parts, the number of remaining parts, and the like.

[0009]

The symbol attached to the carrier tape is read by the head attached to the machine side to erroneously mount components and manage the remaining number of components.

[0010]

EXAMPLE An example of the present invention will be described below.

In FIGS. 1 and 2, on the bottom surface of the concave portion of the carrier tape 1, there is provided a bar code 2 in which codes such as an identification serial number, a part name, characteristics such as resistance value and capacitance of the part, and the remaining number of parts are displayed. It is attached.

A parts assembly 3 having a bar code on the bottom surface of the carrier tape is set in a parts cassette 4, and a bar code reader 6 provided in a head section 5 takes in the information of the bar code 2 into the machine body.

In the above configuration, the component mounting process is shown in FIG.
A description will be given according to the flowchart in FIG.

In step # 1, the parts assembly 3 is set in the parts cassette 4. Next, in step # 2, a mounting check command is input to the mounting machine, and the control unit in the mounting machine is based on the input program, and in step # 3, it is transferred to the parts outlet 8 of the parts cassette 4 on the parts supply unit 7. The bar code 2 attached to the bottom surface of the carrier tape 1 that has moved and become empty of components is read by the bar code reader 6 attached to the head unit 5. Next, the component name read in step # 3 is compared with the component name stored in the mounter to determine whether or not the component is set at a predetermined position, and the result is displayed. If there is a set mistake, it is reset in step # 5 and the process returns to step # 3. If all are set correctly, the process proceeds to step # 6 to start the mounting work.

In order to check the parts out during the parts mounting work, the bar code 2 attached to the bottom surface of the carrier tape 1 of each parts cassette 4 is read in step # 7 to detect the parts out in step # 8. Display a notice.

According to the present invention, as long as a means for reading the bar code 2 attached to the bottom surface of the carrier tape 1 is provided on the mounting machine side, erroneous mounting and remaining of parts may occur regardless of the compatibility of the mounting of the parts cassette 4. Number management can be performed.

[0017]

As is apparent from the above description, according to the component mounting method of the present invention, the parts cassette is provided with the storage means, and the names, characteristic values, and the remaining numbers of the parts are managed in the related art. Compared with the above, since the information of the parts is provided for each tape, the parts characteristics and the remaining number information can be managed regardless of the compatibility of the parts cassette of the mounter manufacturer.
