FIG. 8 is a block diagram showing a configuration of a main part involved in displaying the remaining number of electronic components in the electronic component mounting apparatus 1 described above. As illustrated, the mounting control unit 6 controls the head unit 7 to acquire and store the information of the supply storage unit 12 of each electronic component supply device 2 before starting the mounting. After mounting is started, mounting is controlled by controlling the mounting unit 4, the number of electronic components used for mounting is subtracted from the initial value, and a remaining number display command is issued to the mounting display unit 8.

A mounting process in the electronic component mounting apparatus 1 as described above will be described with reference to a flowchart of FIG. Prior to the start of production, the head unit 7 is controlled by the mounting control unit 6 to read information from the supply storage unit 12 of each electronic component supply device 2 and store it in the mounting control unit 6 in step # 21.

In step # 22, the mounting control section 6 controls the mounting section 4 to mount the electronic components supplied from the electronic component supply devices 2. With the operation of the mounting unit 4 or the electronic component supply device 2, step #
In 23, the storage is updated by subtracting the remaining number of components of the corresponding electronic component supply device 2 stored in the mounting control unit 6 (mounting storage unit 6A).

Next, in step # 24, it is determined whether or not the updated remaining number of components is smaller than the remaining number setting value. If the condition of step # 24 is not satisfied, step # 2
Return to Step 4 and continue the implementation.

If the condition of step # 24 is satisfied,
A command is issued by the mounting control unit 6 and a warning is displayed on the mounting display unit 16 indicating that the remaining number of components is small. FIG. 10 is a block diagram showing a main part configuration related to the remaining number display when efficiently using frequently used electronic components in the electronic component mounting apparatus 1 described above. As shown in the drawing, the mounting control unit 6 determines the mounting position of the electronic component supply device 2 on which the same type of electronic component is mounted based on information of the mounting storage unit 6A by the input device 9 or the like when the component runs out. The information is searched, and if it is found that the corresponding electronic component supply device 2 is also mounted at another position, the electronic component supply device 2 is used as an alternative supply device and the mounting unit 4 continues production.

The mounting process in the electronic component mounting apparatus 1 as described above will be described with reference to the flowchart of FIG. First, in step # 26, a plurality of electronic component supply devices 2 loaded with frequently used electronic components are prepared and attached to the electronic component supply unit 3. Then, in step # 27, the mounting position information in the electronic component supply unit 3 of the same type of electronic component supply device 2 is stored in the mounting storage unit 6A by the input device 9 or the like.

Thereafter, in step # 28, the mounting control section 6 controls the mounting section 4 to start production. Along with this, the storage is updated by subtracting the number of remaining components of each electronic component supply device 2 stored in the mounting control unit 6, and is displayed on the mounting display unit 8.

Then, in a step # 29, it is determined whether or not the component has run out. If the occurrence of parts shortage is not recognized, the process returns to step # 28 to continue the production. If the occurrence of parts shortage is recognized, step # 3
At 0, it is searched from the information in the mounting storage unit 15 whether there is an electronic component supply device 2 mounted with the same type of electronic component as the electronic component supply device 2 that has run out of components. Is determined at different positions of the electronic component supply unit 3.

If there is an electronic component supply device 2 of the same type, in step # 31, the electronic components are supplied from the electronic component supply device 2 so that the electronic components are supplied from the electronic component supply device 2 (therefore, the electronic components are supplied by the mounting section 4). The storage is updated, and the process returns to step # 28 to continue the production.

If there is no electronic component supply device 2 of the same type, the electronic component mounting device 1 is stopped.

[0014]

However, in the above-described conventional technique, in order to know beforehand that a component has run out, it is necessary to refer to information on the remaining number of components in the mounting display unit. Therefore, it is not possible to visually grasp that the parts are almost out. For this reason, the replenishment of components to the component supply device or the replacement of the component supply device is performed only after the occurrence of component shortage, and there is a problem that the setup time becomes long.

Further, when the equipment is operated in an operation in which the type of the electronic component supply device is frequently changed, not only the number of productions per type is reduced, but also it is difficult to make a plan as to which electronic component is required more. It takes time. For this reason, there is a problem that components are cut out at an early stage after the operation of the equipment, and the electronic component mounting apparatus must be stopped, which affects the operation time of the electronic component mounting apparatus.

The present invention solves the above-mentioned problems, so that it is possible to easily recognize that the electronic component supply device is nearing a component shortage, and to prevent the component shortage at an early stage after the operation of the equipment. The purpose is to do.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention stores, in an electronic component supply device, a remaining component number and a remaining number warning value written by a head unit provided in the electronic component mounting device. By providing a storage means, a display means for displaying information on the number of remaining components, and a control means for instructing the display means to display the information based on the information in the storage means, the operator can electronically reduce the number of remaining electronic components. It can be grasped visually from the parts supply device.

Further, a production slot and a replacement slot are provided in the electronic component supply section of the electronic component mounting apparatus, and before starting the production, information on the number of remaining components of each electronic component supply apparatus attached to the production slot is read. By specifying the electronic component supply device with a small number of remaining components and attaching the same type of electronic component supply device to the replacement slot, the electronic component supply device on the production slot may run out of parts during production. In such a case, the production can be continued using the electronic component supply device mounted on the replacement slot.
