JPH06350287A - Method for replacing parts in electronic parts mounter - Google Patents

Abstract

PURPOSE:To reduce manhours in the preparation for replacement of parts while enhancing the operating rate and reliability of a mounter by a constitution wherein a signal including the information representative of the residual number of parts is transmitted to an automatically guided vehicle (AGV) from a parts cassette equipped with a memory and an AGV transfers supplementary parts to a parts replacing site upon receiving the signal. CONSTITUTION:When a decision is made that the number of residual parts stored in a memory of a parts cassette 5 is lower than an arbitrary value, a mounter displays a message on a screen and lights an alarm lamp and a signal transmitting means disposed at the parts cassette 5 transmits information notifying runout of parts to the AGV. The AGV receives the information through a signal receiving means mounted thereon and loads the supplementary parts being transferred to a parts replacing site. A worker replaces the parts after the mounter stops due to run-out of parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component replacement preparation method for an electronic component mounter.

[0002]

2. Description of the Related Art Due to recent innovations in electronics technology, products have become lighter, thinner, shorter, smaller, and diversified. As a result, it is necessary to realize high operation and high quality component mounting in the electronic component mounting machine.

A conventional example will be described below with reference to FIGS. 3, 4 and 5. FIG. 3 shows a schematic configuration diagram of the electronic component mounter. Reference numeral 1 denotes a rotary head, which is provided with a plurality of nozzles 2 and performs suction / mounting of components. An XY table 3 fixes a board on which components are mounted and positions the board under the nozzle 2. Reference numeral 4 denotes a parts supply table, which positions the parts cassette 5 arranged thereon under the nozzle 2, and the nozzle 2 adsorbs the parts supplied by the parts cassette 5. Then, the rotary head 1 is rotated and the XY table 3 is moved to position the mounting position of the component on the substrate, and the nozzle 2 mounts the component on the substrate. The number of parts that can be mounted in the parts cassette 5 is limited, and it is necessary to replace the parts when the parts run out. In addition, 6 is a data communication unit, 7 is a controller, and 8
Is a main operation panel, 9 is a rear operation panel, 10 is a component out cassette display section, 11 is a board loader section, 12 is a board unloader section, and 13 is a camera.

FIG. 4 is a conceptual diagram of a parts cassette and related parts. Parts 15 are attached to the parts cassette 5, and are fixed to the parts supply table 4 by a fixing lever 16. The data communication unit 6 reads data (part name, part data, and remaining number of parts) of the memory 14 of the parts cassette 5, and the read data is sent to the controller 7 and used for various operations. Memory 1
Reference numeral 4 is a part for recording parts names and the like, and the data communication part 6
Data is exchanged with the controller 7 via. The parts 15 are packed in a tape shape and fixed to the parts cassette 5.

Next, FIG. 5 shows a flow chart of the operation of the mounter in the prior art when a component out-of-stock notice occurs and when a component out-of-range occurs, and the work procedure for component replacement preparation will be described. When the production is started in step 13 of the flowchart, the memory 14 is first read by the data communication unit 6 in step 14, and the parts are mounted in step 15. Next, when it is determined in step 16 that the remaining number of parts stored in the memory 14 of the parts cassette 5 is less than or equal to an arbitrary remaining number,
In step 17, the mounting machine displays a message on the screen of the out-of-component cassette display unit 10 and lights a warning light. Further, in step 18, it is judged whether or not the parts are out. If the parts are out, the operation is stopped in step 19 and a message is displayed and a warning light is turned on. After seeing these, the operator determines that the mounting machine needs to be prepared for component replacement, and then starts the preparation. After the mounting machine has stopped due to the lack of components, the worker replaces the component. The mounting machine determines in step 20 whether the component replacement is completed, and if not, waits for the completion.

[0006]

However, in the above configuration, when the operator does not determine that preparation for component replacement is necessary, or when there is such preparation, the operator cannot prepare for some reason. In this case, since the preparation for replacing the component is delayed, there is a problem that the stop time at the time of the component shortage is prolonged and the operating rate of the mounting machine is reduced. In addition, the number of man-hours required for the worker to bring the parts from the parts storage location is increased.

The present invention provides a component replacement preparation method for an electronic component mounter that solves the above problems, reduces the number of preparation work steps for component replacement, and improves the component mounting operation rate and reliability. The purpose is to

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a component replacement preparation method according to the present invention is an electronic component mounting machine having a parts cassette with a memory in a parts supply section, and is used as a parts cassette with a memory or a mounting machine. A means for transmitting a signal is arranged, which is used to transmit the remaining part number information to an automated guided vehicle, while a means for receiving a signal is arranged for an automated guided vehicle or a guided vehicle management system, which is used to unmanned vehicles. The guided vehicle or the guided vehicle management system receives the remaining part number information of the mounting machine, and based on the remaining part number information received by the automated guided vehicle or guided vehicle management system, the required parts are carried by the unmanned guided vehicle to the parts replacement location. It is something that is done.

[0009]

The present invention reduces the man-hours required for the component replacement preparation and shortens the component replacement preparation time with the above-described configuration, thereby increasing the operating rate of the mounting machine and mounting the component with high productivity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A part replacement preparation method according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a flow chart showing an operation procedure of a mounting machine when a parts-out notice occurs and when a parts-out notice occurs in this embodiment, and FIG. 2 is a schematic view of an automated guided vehicle used for this. The description of the outline of the electronic component mounter is based on the above conventional example, and only the added items will be described here.

When it is determined in step 4 of the flowchart that the remaining number of parts stored in the memory of the parts cassette is less than or equal to an arbitrary remaining number, the mounting machine displays a message on the screen and displays a warning light in step 5. Is turned on, and the advance notice information of the parts is sent to the automatic guided vehicle 17 using the means for sending the signal arranged in the parts cassette with the memory in step 6. The automated guided vehicle 17 receives the parts advance notice information using the means for receiving the signal arranged on the automated guided vehicle 17 in step 10, and in step 11, the carrier 1
The replenishment parts are mounted in 8, and the replenishment parts are transported to the part replacement place in step 12. The worker replaces the component after the mounting machine stops because the component is out. The signal from the memory-equipped parts cassette may be transmitted to the automated guided vehicle 17 via an electronic component mounter or an automated guided vehicle management system.
