Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables continuous supply of parts by continuously and sequentially using part or all of a parts supply device in parts supply in an electronic parts automatic insertion machine. It relates to a device for

Conventional example configuration and its problems Conventionally, in the component supply in the electronic component automatic insertion machine, a plurality of cassettes are installed in the component supply device, the electronic components are set in the carrier in the cassette and used sequentially, or the electronic components are taped. Then, a plurality of taping parts are set, and electronic parts are sequentially used from each tape.

However, in any case, the number of components provided at one supply position such as one cassette or one tape is the maximum number of components to be inserted in one component replenishment.

The type of electronic component is determined by the number of cassettes or tapes that can be installed in the component supply device, and the component supply device is becoming larger in order to support multiple types.

However, when electronic components are inserted, a large number of electronic components of a small variety may be inserted, and in such a case, an unnecessary component supply unit may occur in the component supply apparatus of the multi-product mounting system.

As a countermeasure for this, there is a method in which the parts of one component supply part are used up and then the part holding device goes to another part supply part to pick up the parts. In this case, set the same parts in all the supply parts and The method of sequentially using is effective only for the purpose of inserting a large number of electronic components of one type, and has a drawback that it cannot be applied to a plurality of types of electronic components.

An object of the present invention is to solve the above-mentioned conventional problems and provide an automatic component supply position selecting device of an arbitrary pattern system which enables a large number of electronic component automatic insertion machines to be inserted in a small variety without changing the component supply device. The purpose is to

The component supply position automatic selection device of the present invention is a component supply device in which a plurality of component supply units accommodating a large number of components are provided in a row, and a component supply device that detects the presence or absence of a component in the component supply unit,
A storage device that stores the component supply unit divided for each component type as a block, and one component in the stored block that is not included in the component supply unit is detected by the component detection device, and then another component is sequentially detected. After issuing a movement command to the component holding device so as to take out the component from the supply unit, and after taking out the component from the component supply unit in the block has completed, the first component supply unit is replenished with the component and A movement command device that, when detected by a component detection device, commands movement to the component holding device so as to take out a component from the first component supply unit, and the component supply device or the component holding device based on a signal from the movement command device. When the parts supply part is divided into parts according to the parts type in advance and the parts of one supply part in the divided block are lost. It is possible to automatically move the component holding device to the other supply section in the block to continue the component supply and continuously operate the electronic component automatic insertion machine, and it is possible to arbitrarily set the product type block. The component type can be freely installed within the number of supply units of the component supply device.

Description of Embodiments An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the component detection devices 2a to 2h are composed of photoelectric switches and optical fibers, and the component supply unit of the component supply device 1
A quantity equal to the number of 1a to 1h is arranged. Then, each optical fiber is connected to the component supply units 1a to 1h.

The component detection devices 2a to 2h are connected to the movement command device 3 and send information on the presence or absence of components obtained by the component detection devices 2a to 2h to the movement command device 3.

The movement command device 3 is a small computer (hereinafter referred to as CPU).
And a storage device and a measuring device, which are connected to the control device 8 of the electronic component automatic insertion machine.

The component holding device 7 is provided on the insertion head 6, moves up and down by a cylinder, and picks up and mounts a component from the component transfer unit of each of the component supply units 1a to 1h of the component supply device 1. Further, the component holding device 7 moves on the component supply units 1a to 1h by the DC servo motor.

FIG. 2 is a schematic flowchart of this embodiment, and the operation will be described with reference to FIGS. 1 and 2. The block pattern selection input 9 is made by a switch, and the switch determines a block pattern and a product block.

Here, there are two types of product blocks of the component supply units 1a to 1h, which are divided into the component supply units 1a to 1d and the component supply units 1e to 1h,
The former is block 1 and the latter is block 2.

After the product type block has been determined, the movement command device 3 that has input the block 1 as the block selection input 10 from the control device 8 of the electronic component automatic insertion machine has the component holding device 7 based on the information of the internal storage device and the measuring device. The parts supply section of block 1
Move to any 1 point from 1a to 1h. For example, let this 1 point be 1a. At this time, this information is stored in the storage device of the movement command device 3.

At the timing of completion of movement, the movement command device 3 reads the information of the component detection device 2a, and if there is a component, instructs the component holding device 7 to mount the component and mounts the component. Then, the process waits for the next block selection input 10.

If the information indicates that there are no parts, the remaining number of parts is confirmed. The remaining number of components is stored in the storage device as the component data 14 and managed by the CPU.

If there is a remaining number of components, it is determined that there is a component, a component mounting command is output, the component holding device 7 performs component mounting 13, and the next block selection input 10 is awaited. Remaining part data is O
In case of, the CPU confirms the movement data 15 of the movement measuring device,
It is determined whether or not the parts supply unit in the block has completed a cycle.

When the component supply units 1a to 1d in the block have not been completed, the movement command device 3 outputs a movement command to the component supply unit 1b of the component holding device 7 to move the component holding device 7 to the component supply unit 1b. .

After the component holding device 7 completes the movement to the component supply unit 1b, the information of the component supply device 2b is read this time, and the above operation is repeated.

When the above operation is repeated and the operation returns to the component supply unit 1a again,
If there is no component detection signal and the component data remains 0, the component will be exhausted for the first time, and all operations including the component mounting operation will be stopped, and the electronic component automatic insertion machine controller 8 will be notified of the component out information. Is output. Further, when the component supply unit 1a is replenished with components by the time of returning to the component supply unit 1a, this apparatus continues the operation until the artificial machine is stopped.

The above is the description of the present embodiment. In the present embodiment, the number of blocks is two and the number of component supply units 1a to 1h is eight. However, the block pattern can be set arbitrarily, and the component supply units 1a to 1h. It goes without saying that the number of can be increased or decreased arbitrarily.

Further, although the component holding device 7 is moved to select the component supply units 1a to 1h in the present embodiment, the same effect can be obtained by moving the component supply device 1.

Although the component detection devices 2a to 2h are connected to the component supply units 1a to 1h, they may be connected to the component holding device 7 to detect the components of the component supply units 1a to 1h. In addition, the method of component detection is not limited to photoelectric switches,
It is also possible to use a laser or a camera. Needless to say, the movement command device 3 may use an existing NC device without newly installing it.

EFFECTS OF THE INVENTION As described in detail above, according to the present invention, as compared with the conventional component supply device, (1) increase in the number of mounted components per type without modification of the component supply device of the electronic component automatic insertion machine Can be measured.

(2) From the insertion of a small number of electronic components to the insertion of a wide variety of electronic components, one component supply device can be used, and all the component supply parts of the component supply device can be effectively used.

(3) From the above, the operation rate of the electronic component automatic insertion machine can be improved.

It has the effect.
