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 for mounting electronic components.

[0002]

2. Description of the Related Art Conventionally, an electronic component mounting apparatus (hereinafter referred to as a mounting machine), as shown in FIG. 6, has a component cassette 1 mounted in a component supply section, a name of a component mounted in the component cassette 1, and a component A memory 2 storing a code number representing a specification and a symbol, a data reading / writing means 4 for exchanging information from this memory, and a program 12 for instructing which part of a part supply unit should be placed and which part should be held. The program holding means 6 and the parts supply information holding means 8 for displaying the parts shortage cassette information 13 in the parts supply unit when the parts are out of stock are provided, and the operator follows the information of the parts supply information holding means 8 to newly supply the parts cassette. To the parts supply section.

When the supply of the component cassette is completed, the component replacement completion button 7 is pressed to notify the mounting machine of the component replacement completion. Next, whether or not the component cassette mounted on the mounting machine is a correct component is verified by the component verification means 10 before starting the mounting operation, and if there is a mismatch, the display / operation prohibition processing unit 9 Processing such as warning and not starting mounting operation has been performed automatically. Such an operation is usually performed before a new production is started, or when a component shortage occurs during production and the component cassette is replaced with another component cassette.

[0004]

However, in the conventional mounting apparatus, when a component is out of stock and if the operator mistakenly replaces an adjacent component cassette, it is appropriate unless all component cassettes are collated. Parts cannot be collated. When collating all parts cassettes, the communication time between the memory installed in each parts cassette and the data read / write means for reading the information in this memory, the time to move the parts supply unit, and , It takes time to collate with the prepared program for mounting, and much time is lost until collation for all parts is finished and production is restarted. For example, if 300 component cassettes are installed, the time required to collate the components in one cassette is 2
If it takes a second, 600 for matching 300 parts
There is a problem in that a loss of seconds, that is, 10 minutes occurs, and if this occurs every time a part runs out, the operating rate of the device is significantly reduced.

The present invention solves the above-mentioned conventional problems, and provides an apparatus for appropriately collating parts when the parts run out, even if the operator mistakenly replaces the parts cassette without lowering the operation rate of the device. To do.

[0006]

In order to solve the above-mentioned problems, an electronic component mounting apparatus of the present invention stores a name of a component cassette, a component code, etc. of a component cassette mounted in a component supply unit, and a storage unit for storing this information. Data read / write means for reading or writing, part supply information holding means for holding and managing the number of the part supply section in which the cassette of the part out of parts or the part replacement target is mounted, and adjacent parts for managing the number of adjacent part collations Collation information holding means, program holding means for holding a program for mounting electronic components, component collation means for determining whether mounted components are correct, and if the correct components are not mounted, the operator to that effect It is provided with a display and operation prohibition means that the mounting operation is not restarted.

Further, the data read / write means can read / write information of a plurality of component cassettes at a time.

[0008]

With the above construction, when a component shortage occurs in the electronic component mounting process, the component supply information holding means holds the information of the component cassette in the mounting machine where the component shortage occurs. On the other hand, in the adjacent component collation information holding means, the number of component cassettes for performing the component collation with respect to the adjacent component cassette when a component cassette runs out of components is set in advance.

Further, in each of the component cassettes, the component name, the component code number indicating the component specification, and the symbol information are stored in the storage means. In order to read the information in the storage means, move the parts supply unit to the position of the storage means, read the information in the storage means, and check it with the target mounting program to check whether the correct parts are mounted. Find out. At this time, the adjacent component cassettes are collated according to the preset collation number of the component cassettes, and the same collation processing is simultaneously performed up to the adjacent component cassettes.

The display / operation prohibition processing section, which performs the display / operation prohibition processing, displays the result on the display device when the component misidentification is found as a result of the collation processing, and the operator prohibits the restart of production.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. Components having the same configurations as those described in FIGS. 6 and 7 showing the conventional mounting process are denoted by the same reference numerals, and the description thereof will be omitted. FIG. 1 is a block diagram showing a component cassette replacement process when a component runs out in an electronic component mounting process in one embodiment of the present invention. In FIG. 1, each component cassette 1 is equipped with a storage unit 2 that stores the name of an electronic component, a component code number indicating the component specification, and a symbol. For this storage means, for example, a memory backed up by a battery is used. The mounting machine 3 is provided with a data read / write means 4 for reading or writing information in the memory, and exchanges data with the memory in a non-contact state. This data read / write means 4 is fixed to the mounting machine one each on the left and right when the component supply unit is divided into two parts on the left and right, but by moving the component supply unit 5, the information of each component cassette 1 is read. You can get out. On the other hand, the electronic component program 12 currently being mounted
The program holding means 6 holding the information also holds information about which part should be placed in which part of the component supply unit.

When a component shortage occurs, the component supply information holding means 8 is information as to which location of the component cassette in the component supply unit in the mounter the component supply is out, as shown in the flowchart of FIG. The part-out information 13 remains. The operator removes the parts cassette and sets a new parts cassette containing the parts in the parts supply section.

When the work is completed, the operator pushes the part replacement completion button 7 to notify the mounting machine of the completion of the parts replacement. Next, the component supply unit 5 is moved to the position of the storage unit 2, and the components are collated by collating with the mounting program in the storage unit 2. Adjacent parts collation information holding means 1
1 stores information on the number of parts to be collated with respect to the parts cassette adjacent to the replaced parts cassette. It is assumed that when a component cassette runs out of components, it is set so that it can check up to two adjacent component cassettes on the left and right. For example, if the component with the Z number 25 runs out as shown in FIG. 3, the mounting machine uses the Z numbers 23 to 27.
Up to 5 parts cassettes will be collated. This time,
If the time required for part verification is 2 seconds per location, then 2 seconds × 5 locations = 10 seconds.

To compare the component cassettes, the data read / write means 4 is instructed by the component supply information holding means 8, reads the memory mounted in the newly supplied component cassette, and the program held by the program holding means 6 Compare the parts and see if the parts name and part code match,
The verification is performed by the verification means 10.
If the two pieces of information are inconsistent, the display / operation prohibition processing unit 9 displays "mistake of parts" on the display and performs processing such as not restarting production even if the start button is pressed.

It is assumed that the operator can freely set the number of parts to be collated in the adjacent parts cassette. In the present embodiment, the component supply unit is divided into two parts on the left and right sides, and one data reading / writing means is provided on each of the left and right sides. Now, suppose that the data read / write means is provided on each of the left and right sides, and the two right and left adjacent component cassettes are set to collate. For example, if the component with the Z number 25 runs out as shown in FIG. 4, the mounter collates the component cassettes at a total of 5 locations from the Z numbers 23 to 27, but the component supply unit is moved by the Z number. Only two times are required for collating the component cassettes 23 to 25 and for collating the component cassettes of Z numbers 26 and 27. This time,
The time can be further shortened as compared with the case where the component supply unit is moved five times.

[0016]

As described above, according to the present invention, when a component shortage occurs and the component cassette is replaced, the information in the storage means is read out and collated with the target mounting program so that the correct component can be obtained. Whether or not the component cassettes are installed is checked, and at the same time, the adjacent component cassettes are checked according to the preset number of checked component cassettes. The parts can be efficiently collated without collating.
