Abstract

PURPOSE:To enable correction packaging so as to simplify or eliminate postprocessing operation by providing a packaging unit for packaging electronic parts on a substrate, a synchronously operating circular part feeder, and a control unit for enabling non-synchronous motion. CONSTITUTION:Each of a plurality of part holders 3 circumferentially disposed on a ring 7 driven for rotation receives an electronic part 4 and supplies it to a corresponding individual insertion head 1, and as the ring 7 moves a pitch, the part on the insertion head 1 is inserted into a substrate 6. At this time, insertion discrimination is performed by a lower insertion unit 8. The same operation is repeated at an insertion head 2 for another part 5. When any defective is discriminated and requires correction, for example, an empty part holder 3a is selected for correction packaging and is moved to a part supply position by a direct continuous motion, and after receiving a part, it is moved by a direct continuous motion to a position where the part is delivered to the insertion head 1. At this time, the ring 7 can be rotated either forwardly or reversely in such a direction as to permit earlier approach. This control enables correction packaging.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is an electronic component mounting system that sequentially aligns and supplies components to a component holder that is moved in one cycle. The present invention relates to a component mounting apparatus that has a function of enabling collective correction mounting after mounting.

Conventional technology Conventionally, this type of component mounting apparatus was disclosed in Japanese Patent Application Laid-Open No. 59-97924.
As known from the publication, the structure is such that a holder for holding components is disposed on an endless rod that is driven in circulation and is driven in synchronization with the mounting head. That is, as shown in FIG. 3, sprockets 101, 102, 103, 104
A chain 106 is stretched between them, and pallets 106 are fixed on this chain 105 at equal intervals, and this pallet 106 is provided so as to be able to hold one continuous piece of parts. Note that the continuous cut pieces of parts are obtained by cutting a series of parts pulled out from the cage 107 in the supply section 107 and supplied to the pallet 106. Further, the continuous cut pieces of parts on the pallet are held in a predetermined position by a chuck on the rotary disk 109, and then inserted onto the substrate. In this case, the main objective is to keep the posture of the parts held on the pallet constant by the cam and the cam 7 roller.

Problems to be Solved by the Invention However, in this component mounting method, the mounting head and the supply device are synchronized, and when a mounting error occurs and needs to be corrected, the pallet containing the incorrectly mounted component must be moved around the pallet. During the process, certain parts must be held, which increases the time the machine is stopped. Moreover, it does not currently have such a function.

Means for Solving the Problems The present invention solves the above-mentioned problems by synchronizing the circulating component supply section and the mounting section when normal mounting is being carried out, and asynchronously operating when corrective mounting is being carried out. It is characterized by having a control device that enables the following.

Effect: With the above configuration, the present invention does not dedicate a component holder for correction mounting in case of a mounting error, and uses all the component holders after the component is delivered to the mounting section and the previous component supply position. By using a complete component holder, the components to be corrected and mounted can be directly moved to the supply position. The same applies even if the parts supply positions are set at a plurality of positions where the same type of work means or different types of work means are arranged. The component holder during correction mounting is
In order to reach the parts supply position in a short time, rotation can be performed in the forward or reverse direction.

In other words, during component mounting, the component holder always manages the current position from the time the component is supplied to the mounting section until the component is mounted on the electronic circuit board, and only when correction is necessary, the component holder is used asynchronously with the mounting head. It moves directly to the supply position where the parts to be corrected are located.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In this embodiment, multiple types of axial type electronic components 4 with lead wires pulled out in the same direction and multiple types of radial type electronic components 6 with lead wires pulled out in parallel are selectively transferred. An example is shown in which the components are supplied to individual component insertion heads 1 and 2 corresponding to 4.5 and inserted into the electronic circuit board 6.

As can be seen in FIG. 1, a plurality of component holders 3, which serve both for receiving and transferring electronic components 4 and 6, are arranged in a plurality of parts in the circumferential direction of an integral metal ring 7 that is rotatably driven. The arrangement is fixed.

The electronic component 4.6 is supplied to the component holder and simultaneously supplied to the insertion head 1 or 2, and the ring 7 moves one pitch and at the same time inserts the component supplied to the insertion head into the electronic circuit board 6. At this time, if the insertion head 1 is used to insert the mold, the lower mold insertion unit 8 determines whether or not the mold is inserted. If the insertion head 2 is used to insert the mold, the lower mold insertion unit 9 determines whether the mold has been inserted. In this way, parts are inserted into the electronic circuit board 6 and judged, and at the same time as the ring 7 moves one pitch, parts continue to be supplied to the part holder. As the insertion continues as described above, components are supplied from the component holder 3a to the insertion head 1, and the supplied components are mounted on the electronic circuit board 6 by the insertion head 1, and at the same time, the lower mold The insertion unit 8 determines whether the mounting is good or not, and the ring 7 moves one pitch. In this case, if the lower die insertion unit 8 is determined to be defective, it is necessary to determine all component holders for corrective mounting, and one of the multiple component holders 3a to 30 is determined. . In this case, the empty component holder 3a for the same component is used for correction mounting, and the R component is moved directly to the R component supply position in a continuous motion without making one pitch movement, and the R component is placed in the component holder 3a. When the supply is completed, the paper is again moved directly to the delivery position to the insertion head 1. In this case, the ring 7 is moved in the forward rotation direction, but due to the positional relationship between the component supply section and the component holder, the ring 7 may be rotated in the reverse direction in order to move the ring 7 in a closer direction.

Once the component holder 3a has completed its movement to the delivery position to the insertion head 1, components are supplied to the insertion head 1 again, and the supplied components are mounted on the electronic circuit board 6 by the insertion head 1. At the same time, the lower die insertion unit 8 determines the quality of the mounting and the ring 7 moves one pitch. Further, the insertion head 2 also performs the same operation as the insertion head 1.

It is also possible to select cases where there is no need for modified implementation or cases where path operation is required.

In addition to the effects of the invention, according to the present invention, it is possible to carry out correction mounting, which was considered impossible mechanically in one hour, in the sequence method as an electronic component supply method, and it is possible to simplify and omit post-process work.
