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 apparatus and method for mounting an electronic component on a substrate.

[0002]

2. Description of the Related Art As a method for supplying an electronic component in an electronic component mounting apparatus, a method using a parts feeder such as a tape feeder or a bulk feeder is known. In general, a plurality of parts feeders are used side by side in accordance with the type of electronic component to be mounted. Then, each time the type of the board to be produced is changed, the rearrangement of the parts feeder corresponding to the new board is performed. At this time, feeder arrangement data indicating the arrangement of the parts feeders in the supply unit to which the parts feeders are mounted is input, and the pick-up positions of the respective types of electronic components are stored in the mounting device, and according to the feeder arrangement data, An operation of arranging and mounting the parts feeder in the supply unit is performed.

[0003]

However, the required mounting width and the height of the pickup of the parts feeder may differ depending on the type of electronic components supplied to the parts feeder. However, when inputting feeder placement data in a conventional electronic component mounting apparatus, the input order of the parts feeders is simply input without checking the feeder data such as the mounting width of these parts feeders and the height of the pickup unit. I just did.

For this reason, when these parts feeders are actually placed on the table of the supply unit and mounted, when some of the parts feeders protrude from the table and cannot be mounted, or when the height of the pickup unit is increased, Due to the derived constraints, there has been a case where a parts feeder that requires an empty space in an adjacent portion in the width direction is closely attached without the empty space. If such a defect is found after the mounting, the parts feeder must be re-mounted, and the feeder arrangement data must be corrected and re-inputted, which requires overlapping labor and time.

[0005] Further, when the automatic operation is performed while these problems are overlooked, the machine cannot be picked up, which causes a machine trouble. in this way,
In conventional electronic component mounting equipment, it was not possible to perform a prior check for problems with the placement of the parts feeder, and measures were to be taken after a problem occurred. In short, there was a problem that the operability was poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting apparatus and a mounting method for an electronic component which can efficiently arrange a parts feeder and have excellent operability.

A comparing unit that compares the feeder data and the feeder arrangement data to determine whether there is a defect in the actual feeder arrangement, and a feeder arrangement display unit that displays the arrangement of the feeder in the supply unit based on the determination result. With.

According to a second aspect of the present invention, there is provided a method for mounting an electronic component, wherein a plurality of parts feeders for supplying the electronic components are provided in a supply section and picked up by a transfer head to transfer and mount the electronic component on a substrate. In the mounting method, the feeder data of the parts feeder is stored in a feeder data storage unit, and if feeder arrangement data indicating the arrangement of the parts feeder in the supply unit is input, the feeder data and the feeder arrangement data are stored. Are compared to determine whether there is a defect in the actual feeder arrangement, and if there is a defect, that fact is displayed.

According to the present invention, the feeder data of the parts feeder is stored, and when the layout data of the parts feeder is inputted, the feeder data is compared with the layout data to thereby detect a defect in the feeder layout. By judging and displaying the presence or absence of a part feeder, it is possible to prevent a problem of the parts feeder arrangement in advance and perform the parts feeder arrangement with good operability.

First, an electronic component mounting apparatus will be described with reference to FIGS. In FIG. 1, a transport path 2 is provided in the center of a base 1 in the X direction. The transport path 2 transports and positions the substrate 3. Electronic parts supply units A, B, C, and D are arranged on both sides of the transport path 2, and a number of parts feeders 5 are arranged in each supply unit. The parts feeder 5 stores electronic components mounted on the board 3.

An electronic component transfer head 7 is mounted on the X-axis table 6. The X-axis table 6 is bridged with both ends supported by a Y-axis table 8A and a guide portion 8B arranged in parallel to the Y-axis table 8A. Therefore, by driving the X-axis tables 6 and 8A, the transfer head 7 moves in the horizontal direction, and the pickup position 9 of the parts feeder 5 is moved by the nozzle attached to the lower end.
Electronic components are picked up and transferred onto the substrate 3.
A recognition unit 10 for recognizing electronic components is provided on a moving path of the transfer head 7.

Next, the configuration of a control system of the electronic component mounting apparatus will be described with reference to FIG. In FIG. 3, a CPU 11 totally controls each unit described below. The program storage unit 12 stores a sequence program of the mounting operation. The feeder data storage unit 13 stores each of the supply units A,
The characteristic data of the parts feeders 5 arranged in B, C, and D, that is, the data such as the mounting width data of each parts feeder 5 and the data such as the constraint conditions derived from the height of the pickup unit are stored. The feeder arrangement data storage unit 14 stores supply units A, B, C, and D that are set in accordance with the type of board to be mounted.
The data of the order of arrangement of the parts feeder 5 in the storage area is stored. The motor control unit 15 includes an X table 6, a Y table 8
A, The operation of each motor for driving the transfer head 7 is controlled. The comparison unit 17 compares the data in the feeder data storage unit 13 and the data in the feeder arrangement data storage unit 14, and the arrangement of each part feeder indicated in the feeder arrangement data is
It is determined whether or not each of the supply units A, B, C, and D can be actually set without any trouble. The display unit 18 is a monitor, and each of the supply units A,
The arrangement data of each part feeder in B, C, and D is displayed. That is, the marking unit 18 is a feeder arrangement display unit. Here, the occupation status of the parts feeder for each supply unit, and the error location and the contents thereof when set based on the feeder arrangement data are displayed as errors.

This electronic component mounting apparatus is configured as described above, and an electronic component mounting method will be described below.
First, a preparation operation performed by the electronic component mounting apparatus before performing the mounting operation will be described with reference to FIGS. FIG.
When switching the type of the board 3 to be mounted,
2 shows a flow of displaying the parts feeder arrangement corresponding to the type of the product on the screen of the display unit 18.

If the electronic component mounting apparatus has a data generating function, the feeder arrangement data shown in ST1 of FIG. 4 is automatically created by designating the type of the board 3. If there is no data generation function, feeder arrangement data created in advance off-line is input and stored in the feeder arrangement data storage unit 14. Next, the feeder arrangement data and the data of each part feeder stored in the feeder data storage unit 13 are compared and compared (ST2), and these parts feeders are actually stored in the supply units A, B, C, and D. It is determined whether or not the setting can be performed without any trouble when set on the table (ST3).

Here, a description will be given of trouble items that may occur in the feeder arrangement. First, the occupied width of the parts feeder will be described. Each part feeder has a width corresponding to the type of electronic components to be stored, and although this width is standardized, not all parts feeders are the same but have several types of widths. For this reason, when the parts feeders are actually set on the table simply in the order set on the feeder arrangement data, a problem may occur that all the parts feeders cannot be set as data.

Also, depending on the height of the pick-up part of the parts feeder, the nozzle after adsorbing the electronic parts of the adjacent parts feeder may interfere with the moving path, so that a predetermined space is required, and no consideration is given to this. When the parts feeder is simply arranged, the interference between the nozzle and the parts feeder may occur, and the nozzle and the parts feeder may be damaged. As described above, detailed conditions exist individually for the parts feeder arrangement, and if all of these conditions are not satisfied, a problem occurs when the parts feeder is set or when the mounting operation is performed.

In this ST3, when it is determined that there is no problem in the arrangement of the parts feeder, the feeder width is displayed in blue on the display screen (ST4), and when it is determined that there is a problem, Is displayed in red in the feeder width (ST5). Then, it is determined whether or not there is next data, that is, whether or not there is a parts feeder to be further set (ST).
6) If yes, return to ST2 and perform data comparison again. In this way, the results of checking the feeder arrangement data for all of the supply units A, B, C, and D are displayed.

FIG. 6 shows an example of this display. For example, in the supply section A, the parts feeders 51 and 52 are set in order from the left side, and one space is left on the right side. On the right side, five parts feeders 53 to 57 are arranged.
The two of 7 have a red width display (indicated by bold hatching in FIG. 6), indicating that there is a problem in arrangement and that setting cannot be performed as it is.

A similar display is made for the other supply units B, C and D. In the supply unit B, the part feeders 58 to 64 are empty between the part feeders 59 and 60 and between the part feeders 63 and 64. An example is shown in which a space is provided, and an example in which the parts feeders 65 to 75 are arranged in close contact over the entire space in the supply section C. In the supply unit D, the parts feeders 76 to 85 are arranged, and among them, the parts feeder 83 is displayed in red, which indicates that there is a defect in the arrangement.

When rearranging the parts feeders in each supply unit, the operator can perform the work while referring to this display screen. Therefore, the operator checks the space occupancy of the parts feeders, and finds out which part has a defect. Work can be performed while accurately confirming that there is. Therefore, the rearrangement work can be performed efficiently and accurately without reworking due to a defect.

Next, the flow of FIG. 5 will be described. FIG. 5 is a flowchart of a data check performed after inputting feeder arrangement data. ST11 to ST shown in FIG.
16 is the same as ST1 to ST6 in the flow of FIG. 4, and in FIG. 5, it is determined in a subsequent step that there is data when the parts feeder cannot be set (ST
17), an error is displayed on the screen (ST18), and feeder arrangement data is created. In this case, ST14,
5 may or may not be displayed. The data may be compared, and if there is a defect in the feeder arrangement data, an error display may be performed.

That is, on the data check screen, the number of the parts feeder having a defective arrangement is displayed. As a result, it is possible to detect a malfunction of the feeder arrangement before starting the automatic operation, and it is possible to prevent the machine from stopping due to a machine trouble caused by the malfunction after the start of the mounting operation. After the error is displayed, the feeder arrangement data is re-created. In this case, if the mounting apparatus has a function of automatically re-creating the data, the data is automatically created.

Thereafter, the mounting operation is started. In FIG. 2, the substrate 3 is positioned at a mounting position on the transport path 2. Next, the X-axis table 6 and the Y-axis table 8A are driven to move the transfer head 7, and a predetermined electronic component is picked up at the pickup position 9 of the parts feeder 5.
Thereafter, the transfer head 7 moves above the recognizing unit 10, where the position of the electronic component is recognized. Based on the recognition result, position correction at the time of mounting on the board 3 is performed, and the electronic component is mounted on the board 3.

[0025]

According to the present invention, the feeder data of the parts feeder is stored, and when the placement data of the parts feeder is input, the feeder data is compared with the placement data to determine whether there is a defect in the feeder placement. Is determined and displayed, it is possible to prevent a defect in the parts feeder arrangement in advance. At the time of rearranging the parts feeders, the work can be performed according to the display screen, so that the rearrangement work can be performed accurately with good operability.
