Abstract

PURPOSE:To protect a production line from a long time suspension due to the components being out of stock. CONSTITUTION:The names and quantities of components loaded on a component supplying device 4 are stored in a storage section 7 installed to the component supplying device 4. Every time when a component is picked out from there, an arithmetic operation section deducts '1' from the quantities of components stored in the storage section 7, thereby rewriting the storage. A receiving and transmitting section 8 of a packaging machine reads the names and quantities of loaded components stored in the storage section 7 of the component supplying device 4 where a control section 10 of the packaging machine computes the quantities of components required for the production and informs a worker of the preparation of components to be supplied.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component mounting method that minimizes a work stop time due to component shortage by providing a step of giving a worker a notice of component shortage.

[0002]

2. Description of the Related Art FIG. 6 is an external view of an electronic component mounter 1. Reference numeral 2 is an operation panel, 3 is a monitor screen, 4 is a component supply device, and 5 is a component tape that continuously holds components on a tape base material, which is wound around a ring-shaped winding frame.
6 is a warning light. When the production model is decided and the mounting work is started, conventionally, an operator uses the operation panel 2 and the monitor screen 3 to examine the arrangement of the component supply device 4 and the number of components to be mounted and prepare the necessary components. In addition, when it is predicted that the parts will run out, the parts supply device 4 equipped with the replacement parts is prepared.

[0003]

However, recent electronic component mounters have come to use a large number of component supply devices ranging from several tens to several hundreds. The above-described conventional method for preparing parts imposes a heavy burden on the operator. In addition, when using a component supply device that is not a new product but has a component tape that has been used to some extent, it is not possible to know the exact number of components installed, so it is sometimes possible to stop the production line due to an unexpected component exhaustion. is there.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an electronic component mounting method which does not cause a long stoppage of a production line due to a shortage of components.

[0005]

In order to achieve the above object, in the electronic component mounting method of the present invention, the names and quantities of the components mounted by the component supply device are stored in a storage section provided in the component supply device. And the step of rewriting the memory by subtracting the quantity of components taken out from the component supply apparatus from the quantity of components stored in the storage unit by the arithmetic unit provided in the component supply apparatus, and the transmitting / receiving unit of the mounting machine. The process of reading the names and quantities of mounted components stored in the storage unit of the component supply device, and the control unit of the mounting machine calculates the number of components required for production, and prepares the supplementary components for out-of-components. And a step of notifying.

[0006]

Since the worker prepares the supplementary parts according to the notification, the production line will not be stopped for a long time due to the shortage of parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a mounting machine to which the electronic component mounting method of the present invention is applied. In the figure, 1 is an electronic component mounter, 3 is a monitor screen, 4 is a component supply device, 6 is a warning light, and 7 is a storage unit of the component supply device.
The name of the mounted component and the remaining quantity are always stored, and it is retained by the built-in backup battery even when it is removed from the mounting machine. Reference numeral 8 is a transmission / reception unit that reads out data in the storage unit 7 of the component supply device to the mounting machine side, and 9 is a storage unit of the mounting machine, which stores data such as a machining program of a production model. Reference numeral 10 denotes a control unit which controls the mounting machine according to the processing program and gives advance notice of the component supply device 4 running out of components. The operator is informed of the advance notice of the parts running out by displaying the monitor screen 3 and blinking the warning light 6.

With the above configuration, a flow for giving advance notice to the operator of the replenishment of a component shortage of the electronic component mounter will be described with reference to the flowchart of FIG. In step # 0, the calculation unit (not shown) of the component supply device subtracts “1” from the component mounting quantity stored in the storage unit 7 every time a component is taken out, and the storage unit 7 stores the result. Keep it.

In step # 1, the transmitting / receiving unit 1 reads out the component names and the component mounting quantities of the electronic components mounted from all the component supplying devices 4 after a large number of component supplying devices 4 are set in the mounting machine.

In step # 2, the control unit 10 determines in step # 1.
From the information read in step 3, a component supply device number (hereinafter referred to as Z number) mounted, a component name and a component mounting quantity comparison table (hereinafter referred to as component supply array table) are created as shown in FIG.

In step # 3, the control unit 10 reads out the program of the production model and the planned production quantity stored in the storage unit 9 of the mounting machine, and calculates the component name of the electronic component and the number of the components required for the production model. Then, a table is created in the order of arrangement of the component supply devices as shown in FIG.

At step # 4, the control unit 10 makes the step #
According to the parts supply arrangement table created in 2 and the parts name and number of parts required for the production model calculated in step # 3,
It is determined whether or not the planned number of boards can be mounted with the number of components currently arranged in the mounting machine, and if they cannot be mounted, the name of the missing component and the number of components are calculated. If 250 parts are used in each of the production models, the remaining parts of the A part having the Z number 1 and the E part having the Z number 6 in FIG.

In step # 5, the control section 10 determines
Z not used by the parts supply arrangement table created in 2
Ask for a number. In this case, Z number 5 in FIG. 5 is not used.

In step # 6, the control unit 10 determines in step #
The Z number of the component supply device which is not used in the production model is obtained from the component supply arrangement table created in 2 and the component name obtained in step # 3. In this case, it can be seen that Z numbers 5 and 8 in FIG. 4 are not used.

In step # 7, the control unit 10 determines in step #
Fig. 3 shows the names of parts and the number of parts that are insufficient for production calculated in step 4, and the Z numbers 5 and 8 obtained in steps # 5 and # 6.
As shown in, the display section 4 displays that the A and E parts that are lacking in the Z numbers 5 and 8 are mounted as supplementary parts, thereby notifying the operator of the parts supply device that needs to be supplemented when the parts run out. Notify the replacement notice of the parts supply device.

[0016]

As described above, according to the present invention, data for designating a component supply device to be used as a supplementary component when an electronic component mounting machine runs out of components is automatically created, so that a load by an operator for creating data can be reduced. It is possible to realize the improvement of the component mounting quality by preventing the data creation error and the utilization rate by maximizing the use of the component supply device.
