On the other hand, the peeled cover tape 23 is wound around a cover tape reel, and the carrier tape after the electronic component 21 is adsorbed is finely cut by the tape cutter device 31. In this embodiment, the dimension to be cut is a dimension corresponding to the filling pitch.

  The tape cutter device 31 is provided over substantially the entire area of the tape feeder 3B whose lateral width is juxtaposed to the feeder base 3A by mounting brackets.

  FIG. 4 shows a front view of the tape cutter device. This tape cutter device is used to cut each electronic component storage tape 20 after the electronic component 21 is taken out. In the present embodiment, as shown in FIG. 4, the tape cutter device is fixed to the feeder base 3A using an attachment portion.

  This tape cutter device is a drive motor capable of forward and reverse rotation, and a timing belt 63 is stretched between a pulley 61 provided on an output shaft of the drive motor and a pulley 62 provided on a driven shaft. A cutter unit 64 is fixed to the timing belt 63.

Hereinafter, attachment / detachment between the component supply device 3 and the electronic component mounting device 1 will be described.
As shown in FIG. 5, the component supply device 3 is provided with a cart 53 in which a large number of tape feeders 3B are arranged in parallel, and a plurality of locking portions provided on the tape feeder 3B and the cart 53 are locked and unlocked. The tape feeder 3B and the cart 53 are provided so as to be attachable and detachable by being locked.

  Furthermore, the component supply device 3 is detachable by locking and unlocking the electronic component mounting device 1 and a locking portion (not shown).

  By the way, when the production model is changed from the printed circuit board P to the new printed circuit board P ′, the arrangement of the tape feeder 3B is changed by comparing the part type of the existing production model with the part type of the new production model to be produced. It is determined whether or not it is necessary. As a result of the determination, if only the layout of the components arranged on the printed circuit board P ′ is different, only the arrangement of the tape feeder 3B is changed. Further, when the types of components arranged on the printed circuit board P ′ are also different, it is necessary to replace the component supply reels that store different components.

In order to change to an electronic component storage tape that stores different electronic component types, it is necessary not only to change the arrangement of the tape feeder 3B but also to change the tape reel itself.
With the above-mentioned tape feeder replacement or tape reel replacement, the following work occurs.
In the conventional method, the tape cutter device 31 is not provided on the component supply device side, but is provided on the electronic component mounting device side. Therefore, as described above, when a new production model is changed, the electronic component storage tape that is wound around the tape cutter device 31 in either case of changing the arrangement of the tape feeder 3B or replacing the tape reel 52. 20 is separated from the main body of the tape feeder 3B, and then the tape feeder 3B needs to be removed from the feeder base 3A.
Therefore, removal is usually performed by an operator, but it takes time to remove, which has been a problem in terms of productivity improvement.

  In the first embodiment, the electronic component is supplied by supplying the electronic component storage tape using the tape feeder. However, as will be described later, electronic components, particularly large electronic components, are usually supplied using a tray feeder using a component tray.

  When a tray feeder is required, for example, if production is currently performed using a tape feeder, the cart 53 in which a plurality of tape feeders 3B are mounted, that is, the component supply device is removed, and a new tray feeder is removed. It is necessary to replace the feeder 11 with the feeder 11 (see FIG. 7).

  Also in the case of the replacement, in the case of the conventional method, the tape feeder 3B and the electronic component storage tape 20 after the electronic component 21 connected to the tape cutter device 31 is taken out are connected to the tape cutter on the electronic component mounting device side. An operation of winding from the device 31 is necessary. After the operation was completed, the component supply device 3 had to be detached. For this reason, there is a problem that it takes extra time to wind up the electronic component storage tape 20 during the replacement. In particular, in recent years, there is a strong tendency for small quantities and a wide variety of products, and therefore, production is constantly changing and the frequency of exchanging component types is increasing. For this reason, reduction of the time required for this replacement is important for improving productivity.

  On the other hand, according to the method shown in the first embodiment, when the electronic component mounting apparatus 1 and the component supply apparatus 3 are separated or mounted, the electronic component storage tape wound on the tape cutter apparatus 31 as described above is used. The winding work is not necessary, the working time is shortened, and the productivity can be improved.

  The reason is that, as described above, the tape cutter device 31 is attached to the feeder base 3A on the component supply device side, and the electronic component storage tape is not connected to the electronic component mounting device. Therefore, it is possible to move the component supply device 3 independently from the electronic component mounting device 1 without winding up the electronic component storage tape when attaching and detaching.

  Next, the second embodiment will be described with reference to FIG. 6, but only the configuration different from that of the first embodiment will be described.

  In the first embodiment described above, as shown in FIG. 3b), the carrier tape after the electronic component 21 is adsorbed is directly fed to the tape cutter device 31, and is finely cut to a size corresponding to the filling pitch. Go.

On the other hand, in FIG. 6, the tape of the electronic component storage tape provided in order to more surely take the carrier tape into the desired path on the way in which the carrier tape after the electronic component 21 is adsorbed is sent to the tape cutter device. The guide member 41 will be described below.
A tape guide member that guides the electronic component storage tape 20 after the electronic component 21 is taken out between the pair of holding portions is provided over substantially the entire area of the tape feeder 3B having a lateral width arranged in parallel. It has a rectangular tube shape with an open bottom surface, and its lower end extends to substantially the same level as the upper end of the attachment portion 35.

  Here, the tape receiving port of the tape guide member 41 is set to have a size larger than the height L2 of the tape discharge port of the tape feeder 3B, assuming that the height is L1. By doing so, the discharged tape can smoothly advance into the tape guide member.

  Next, a third embodiment will be described with reference to FIG. 7, but only a configuration different from that of the first embodiment will be described.

  The first embodiment described above is an example in which the component supply device 3 is disposed at least one outside of the transport device 2, for example, the front side of the transport device 2 and the printed circuit board P is on one transport device 2. However, in the second embodiment, as a parts supply device disposed outside the conveyor device 2, the tray feeder 11 and the tape feeder 3B arranged side by side on the feeder base 3A are arranged. This is an example in which one printed circuit board P is positioned in a portion.

  The tray feeder 11 includes, for example, a magazine 12 that stores a plurality of pallets 14 on which trays 13 in which a large number of electronic components are arranged and arranged, a drawer mechanism that pulls out a predetermined pallet 14 of the magazine 12, and the drawer mechanism Is provided with an elevator mechanism that raises the pallet 14 pulled out to the electronic component supply position. However, the present invention is not limited to this, and any structure may be used as long as it is a component supply device that supplies electronic components using the tray 13.

  In the third embodiment, the Y-direction linear motor and the X-direction linear motor corresponding to the beams 4A and 4B are controlled by the suction nozzle 5 of the mounting head 6 provided in each of the beams 4A and 4B. An electronic component can be taken out from any of the component supply apparatuses.

  As described above, even when a component feeder is replaced from a tape feeder that has already been installed to a tray feeder, if the component feeder according to the present invention is used, the device can be easily replaced in a short time, and the production efficiency can be improved. Can be improved.

In Example 1 mentioned above, although the example which provides the tape cutter apparatus 31 in the components supply apparatus 3 was shown, in this Example 4, a different form is shown.
In the following description of the fourth embodiment, only the configuration different from that of the first embodiment will be described.

  When starting production using different electronic component types, a tray feeder may be required instead of a tape feeder depending on the type of electronic component. For example, if production is currently performed using a tape feeder, the cart equipped with a plurality of tape feeders, that is, the component supply device is removed and replaced with a new component supply device equipped with a tray feeder. There is a need to.

  Also in the case of the replacement, in the case of the conventional method, the tape feeder and the electronic component storage tape after the electronic components connected to the tape cutter device are taken out are wound up from the tape cutter device on the electronic component mounting device side. Work is necessary. After the operation was completed, it was necessary to remove the component supply device. For this reason, at the time of replacement, there is a problem that it takes an extra time to wind up the electronic component storage tape.

  Therefore, in the present embodiment, the carrier tape after the electronic components discharged from the tape feeder 3B are taken out without being provided with the tape cutter device 31 shown in FIG. 5 or 6 is directly cut into the cart without being cut. What is necessary is just to store in the carrier tape storage container 51 provided in 53.

  Thereby, the component supply apparatus 3 becomes more compact, and the apparatus cost can be reduced.

  Further, it goes without saying that the component supply device, which is the object of the present invention, can be easily detached from the electronic component mounting device in a short time to improve the production efficiency.

  As described above, the first to fourth embodiments of the present invention have been described. However, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is within the scope of the present invention. It encompasses various alternatives, modifications or variations as described above.
