The component management computer 40 is preferably installed in the component preparation area Ab, but may be installed in another area. Also, instead of providing the component management computer 40, the above-described component management function of the component management computer 40 may be mounted on the electronic component mounting machine management computer 30 or the component registration computer 60. It may be. In this case, the operator of the electronic component mounting machine management computer 30 or the component registration operator OP1 of the component registration computer 60 also has the role of the component management operator OP2.

The component registering combo 60 installed in the receiving area At shown in FIG. 1 is for registering the electronic component reels R received in the receiving area At. As shown in FIG. 8, the component registration computer 60 has a control unit 61, and a communication unit 62 connected to the control unit 61 has an electronic component mounting machine 2 via a LAN 50. 0, connected to electronic component mounter management computer 30 and component management computer 40.

The CPU executes a predetermined program to perform control for managing the electronic component reel R. RAM temporarily stores variables required for executing the program, and ROM stores the program.

The control unit 61 is connected to an input unit 63, an output unit 64, a rewritable storage unit 65, a barcode reader 66 and a barcode printer 67, and the input unit 63 is used by an operator. They operate and enter necessary information and data. The output unit 64 displays various states related to control. The storage unit 65 stores the ID of each electronic component reel R, the mounted component name, and the number of mounted components in association with each other. The bar code reader 66 reads a per code label originally attached to the electronic component reel R and acquires the mounted component name and the number of mounted components. The bar code printer 67 prints the ID of the electronic component reel R, the name of the mounted component, and the bar code label Ra indicating the number of mounted components.

The computer 60 for registering parts registers an ID on an electronic component reel in which the name of the mounted parts and the number of mounted parts are input by the input operation of the parts registration operator OP 1 or the bar code reader 66. The ID of each electronic component reel R, the mounted component name, and the number of mounted components are stored in association with each other automatically.

Next, the operation of the electronic component mounting system configured as described above will be described with reference to the flowchart of FIG. The control units 21, 31, 41, 61 of the electronic component mounting machine 20, the electronic component mounting machine management computer 30, the component management computer 40, and the component registration computer 60 are the same. Each of them performs their own processing in parallel, and exchanges data as necessary. Is going.

The component management computer 40 repeatedly executes a program corresponding to the above-mentioned flow chart every predetermined short time. Each time the part management computer 40 starts executing the program in step 100 of FIG. 9, the part reel management routine 40 executes the parts reel management routine in steps 102, 104, and 106. Each part remaining number management routine and the parts replenishment notice routine are executed.

When the component management operator OP2 sets the electronic component reel R in the component supply device Df, the barcode labels Dfa and Ra attached to both are read by the barcode reader 43a, and the information is read. -The ID of the component supply device Df indicated by the code label Dfa is associated with the ID of the electronic component reel R, the name of the mounted component, and the number of mounted components, which are indicated by the barcode label Ra. And register. That is, when the feeder component information is input by the component management operator OP2, the component management computer 40 enters the feeder component information DB shown in FIG. 6 in the component reel management routine shown in FIG. Additional registration of new feeder part information is performed (steps 202 and 204).

Next, the component management computer 40 executes the remaining component count management routine shown in FIG. Specifically, the ID of the component supply device D f in which the component has been consumed in mounting the component on the board from the electronic component mounter 20 (or the computer 30 for managing the electronic component mounter) and the consumption of the component. When the number is received, the feeder component information of the component supply device D # of the corresponding ID is read from the storage unit 45 (steps 302, 304), and the consumed number is subtracted from the remaining component number. Then, the feeder component information is updated and registered in the storage unit 45 as a result of the subtraction as a new component remaining number (step 300). As a result, the component management computer 40 counts all remaining components of the component supply device D f set in the electronic component mounter 20 connected via the LAN 50. to manage.

Then, the parts management computer 40 executes a parts replenishment notification routine shown in FIG. In step 402, the component management computer 40 determines whether the flag F force S is "0". Flag F is a flag indicating whether or not the component management computer 40 has received the production time per board from the electronic component mounter 20 or the electronic component mounter management computer 30. When "1", it indicates that the production time has been received. Since the flag F is reset to `` 0 '' when the component management computer 40 is started, the component management computer 40 determines YES and NO in steps 402 and 404, respectively. Proceed to step 4 to terminate the execution of this program.

When the component management computer 40 receives the production time per board from the electronic component mounting machine 20 (or the electronic component mounting machine management computer 30), it determines YES in step 404. Then, in step 400, the flag F is set to “1”. As a result, the program can be determined to be NO at step 402 next time, and the program can proceed to step 408 by skipping the processing of steps 404 and 406.

The component management computer 40 reads out all the IDs of the component supply devices D ί currently involved in the production based on the feeder position information DB shown in FIG. 7, and reads the feeder component information of those component supply devices D f. It is read from the feeder part information DB stored in the storage unit 45 (step 4 08), and the part supply time when the part supply device D f is out of parts is calculated from the remaining number of parts and the production time, and the calculation result is included. The registered feeder component information is updated and registered in the feeder component information DB (step 410). Thus, the component management computer 40 manages all the component outage times of the component supply device D f set in the electronic component mounter 20. In addition, when parts run out The interval is calculated by the following equation (1).

(Number 1)

Parts remaining

X Production time

Number of parts used per board

The number of components used per board is obtained from the electronic component mounter 20 or the electronic component mounter management computer 30.

Next, the component management computer 40 displays the component supply devices D f on the display unit 44 in ascending order of the component outage time calculated in step 410 (step 412). Specifically, as shown in Fig. 13, the ID of the component supply device D f is used as a key, and the set position of the component supply device D f is displayed. . The feeder set position indicates a line ID, an electronic component mounter ID, and a set position ID in order from the left, and specifies a place where the component supply device D f is set. As a result, the part supply device D f at which a part runs out can be notified to the parts management operator OP2 together with the time at which the part runs out.

Also, the component management computer 40 monitors the component supply device Df that is running out of components during production, and warns the component supply device Df. Specifically, the production completion time is calculated from the planned number of productions and the production time (step 4 14), and when the production completion time is shorter than the part outage time compared with the previously calculated part outage time, The component supply device Df determines that the component has run out during production, and displays a warning on the display unit 44 (steps 4 16 and 4 18). As a result, even if the parts outage time is the same or longer, the parts supply device D f for which parts replacement should be performed with priority can be notified to the parts management operator OP2. In addition, if parts are replenished to the parts supply device D f where the warning was issued, the production completion time will be longer than the parts outage time. It is determined that parts will not run out during the operation, and the warning on display section 44 is released (steps 4 16 and 4 20). The production completion time is calculated by the following equation (2). (Equation 2)

Production quantity X Production time

The planned production quantity is obtained from the electronic component mounting machine 20 or the electronic component mounting machine management computer 30 power.

The component management operator OP 2 preliminarily sets the component supply device D f having the electronic component reel R required for the electronic component mounter 20 based on the notice or warning of component shortage by the component management computer 40 described above. This is to prepare and deliver to the shelf T as of the electronic component mounting line 10 constituting the corresponding electronic component mounter 20 before the components run out.

In addition, the information about the above-mentioned warning about running out of components issued by the component management computer 40 is transmitted to the electronic component mounter 20, and the electronic component mounter 20 also issues a warning. As a result, the operator OP 3 of the electronic component mounter 20 takes out a new component supply device D f instead of the component supply device D f used to run out of components from the shelf T as which is delivered and stored in advance. To the component supply unit 27 of the electronic component mounter 20.

As is apparent from the above description, in the present embodiment, when the component supply device D f that detects a component exhaustion during board manufacturing is detected, the component management computer 40 transmits the component supply device D f The part management operator OP 2 in the parts preparation area A b notifies the part management operator OP 2 of the remaining time when the parts run out and the remaining time when the parts run out. Prepare the supply device D f and transfer the prepared component supply device D f to the time when parts are exhausted (delivery time from the component preparation area A b to the production area A s, the component supply device D f to the electronic component mounting machine 2). (It is preferable to consider the time of wearing at 0) Delivered to the electronic component mounting machine 20 in the production area As. Then, the new component supply device D # is mounted on the component supply unit 27 by the operator # 3 of the electronic component mounter 20. The electronic component mounter 20 detects that the new component supply device D f has been attached to the component supply unit 27, and when the component supply device D f, which is used to cut components, runs out of components, a new component supply device D f. Parts will be sampled from D f. Therefore, since the component management operator OP 2 performs the component preparation work which was previously performed by the operator OP 3 of the electronic component mounting machine 20, the burden on the operator OP 3 of the electronic component mounting machine 20 can be reduced. . Also, by setting a new component supply device D f to the electronic component mounter 20 before the component runs out, the component can be supplied, and the electronic component mounter 20 is not stopped. It is possible to prevent a decrease in the operation rate of the electronic component mounting machine 20 due to replenishment. Furthermore, since the parts management operator OP 2 can centrally manage the parts in the parts preparation area A b and operate the parts efficiently, the parts cost can be reduced as a whole. .

In the above embodiment, the case where the component supply device D f of the electronic component mounter 20 runs out of parts during production will be described. Although it was specified as the component supply device D f to be set in the mounter 20 (steps 410 to 418), when the type of board to be produced is changed, that is, when the setup is changed for the next production The present invention can also be applied to the present invention. In this case, the component management computer 40 grasps a plurality of board types on which components are to be mounted and the component types mounted on each board type, and obtains all the component types mounted on the next board type to be produced. The component supply device Df of the component is specified as the component supply device Df to be set in the electronic component mounter 20, and the component supply device Df thus identified and the production start time of the next board type to be produced are determined. Parts management operator Notice to Data OP 2. The production start time is a set time at which the component supply device D f should be set in the electronic component mounter 20. The remaining time until the start of production may be displayed together, or only this remaining time may be displayed.

According to this, when there is a board type to be produced next, the component management combinator 40 notifies the component management operator OP 2 of the component supply device D f and the production start time for the board type. The component management operator OP2 in the component preparation area Ab prepares the component supply device Df for the next board type to be produced, and prepares the prepared component supply device Df by the production start time. The product is delivered to the electronic component mounting machine 20 in the production area A s. Then, the new component supply device D f is set by the operator OP 3 of the electronic component mounter 20. Therefore, the setup can be changed by setting a new component supply device D f to the electronic component mounter 20 before or immediately after the completion of the current production, and the operation of the electronic component mounter accompanying the setup change can be performed. The rate can be prevented from lowering as much as possible.

Also, in the component replenishment notice routine of the above embodiment, the component outage time was calculated based on the number of remaining components and the production time per board. However, the component outage time was calculated based on the remaining number of components and the mounting time per component. Time may be calculated. In this case, the component management computer 40 receives the component mounting information (see FIG. 14) from the electronic component mounting machine 20 (or the electronic component mounting machine management computer 30), and receives the component mounting information. Calculates mounting completion time information (see Fig. 15.) for each component type (mounted component name) based on the. The component mounting information includes the component mounting order, the component ID, the mounted component name (component type), the mounting time, which is the time required from the time when the previous mounting was completed to the time when the next mounting was completed, and the mounting order. It is composed of the total time obtained by integrating the mounting time. The mounting time can be obtained by actual measurement or calculation. Wearing Completion time information consists of a component ID and mounting completion time.The same mounting component name is picked up from the component mounting information, and is created by associating the component ID with the mounting completion time in the component mounting order. is there. For example, the mounting completion time information of the mounted component name RA001 created from the component mounting information of FIG. 14 is shown in FIG. In other words, component IDP001, which is the first component of scale 01, has been mounted on the board and mounting has been completed at the elapse of ta, and component IDPO50, the second component of RAO01, has started mounting the board. The mounting of the component IDPO 51, which is the third component of RAOO 1, is completed when T 3 has elapsed.

The component management computer 40 reads out all the IDs of the component supply devices D f that are currently involved in production based on the feeder position information DB shown in FIG. 7, and reads the feeder component information of those component supply devices D f. The feeder component information read from the feeder component information DB stored in the storage unit 45, and the component supply device Df calculates the component outage time at which the component supply device Df will run out of components based on the number of remaining components and the mounting completion time, and includes the calculation result and includes the calculation result Is updated and registered in the feeder parts information DB. Thus, the component management computer 40 manages all the component outage times of the component supply device D f set in the electronic component mounter 20. The component outage time is the sum of the quotient of the number of remaining components divided by the amount of components used per board multiplied by the production time per board, and the mounting completion time corresponding to the remainder of the division. Represented by According to this, the component outage time can be calculated more accurately.

Further, in the above embodiment, the present invention is applied to the robot-type electronic component mounter 20. However, the present invention may be applied to a rotary-type electronic component mounter. In a rotary type electronic component mounting machine, a mounting head for picking up and mounting electronic components is fixed rotatably, and after picking up components from a component supply unit fixedly slidable, the components are conveyed by a loader unit. XY tape It is mounted on a substrate positioned by a tool (movable in the X-axis and Y-axis directions). In this case, since the component supply unit slides while the electronic component mounting apparatus 20 is operating, the production area A s is stopped after the component supply device D f has run out of components and the electronic component mounting machine 20 stops. The new component supply device D f delivered to the electronic component mounter 20 is replaced and mounted on the component supply unit 27 by the operator OP3 of the electronic component mounter 20. However, even in this case, in the production area As, there is no need to set the electronic component reel R to the component supply device Df. By setting to 0, parts can be replenished, and even if the electronic component mounter 20 is stopped, the time is kept as short as possible, thus preventing a decrease in the operating rate of the electronic component mounter 20 due to component supply. Also, in the above-described embodiment, a case has been described where the component supply device D f is a feeder-type component supply device to which the electronic component reel R is detachably attached. However, the present invention is not limited to this. The present invention can also be applied to a tray type, a stick type, a balcar cartridge type, and the like.

Also, in the above embodiment, the component registration computer 60 installed in the receiving area At will notify the component registration operator OP1 of the component supply device to be set in the electronic component mounter 20. It may be. Thus, the electronic component reel R to be set in the electronic component mounter 20 can be preferentially delivered to the component preparation area Ab. Industrial applicability
