Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component supply device in an electronic component mounting apparatus.

Conventional technology Recently, with the expansion of the field of electronic component mounting, electronic components are also becoming more diverse, from their appearance to their functions. One of the important functions required of a component mounting device is whether it can be mounted on an electronic device. Therefore, electronic component supply equipment can also be used at higher speeds.
The ability to accurately supply parts is required.

Hereinafter, an example of the above-mentioned conventional component supply device will be described with reference to the drawings.

FIG. 3 shows an example of an electronic component mounting apparatus.

In FIG. 3, 12 is a component supply device, 13 is an electronic component sucking/mounting nozzle (hereinafter simply referred to as a nozzle), 14 is an electronic component, 15 is an electronic component regulating device, 16 is a board, 17 is a head, and 18 is an X -Y table.

The operation of the electronic component mounting apparatus configured as described above will be explained below.

First, the nozzle 13 that has picked up the electronic component 14 from the component supply device 12 is sent to the electronic component regulating device 15 by the intermittent rotational movement of the head 17, where the posture of the electronic component 14 is regulated, and then the nozzle 13 is moved again to the head 17. The X-Y table 18 is positioned so that the predetermined position of the substrate 16 matches the mounting position, and then the nozzle 13 is moved to the mounting position by intermittent rotational movement.
descends and mounts the electronic component 14 on the board 16.

FIGS. 4 and 5 show the configuration of a conventional component supply device and the configuration of a tape pressing section.

In FIG. 4, numeral 19 is a parts reel around which tape containing chip parts is wound. 2o is a pin that rotatably supports the parts reel 19. 21 is a reel holder, which fixes pin 2°. 22 is a tape which has been taken out from the parts reel.

A tape presser 23 presses the tape 22 at a position immediately before a take-out position 26 where the electronic component is taken out from the tape 22. 24 is a plate;
25 is a tape conveyance path section. 28 is a wheel, which is hooked onto the feed hole of the tape 22 (see 37 in Figure 6).
This rotational action feeds the tape one pitch at a time.

A pin 27 is fixed to the conveyance path 26 and rotatably supports the wheel 28.

FIGS. 5a to 5c are diagrams showing the details of the vicinity of the tape holding part 23.

A pin 29 rotatably supports the tape presser 23. 30 is a nut, and pin 29 is connected to plate 2.
It is fixed at 4. 31 indicates a tape conveying surface.

Reference numeral 32 is a threaded coil spring, which is wound around the pin 29. One end presses the top surface of the tape holder 23, and the other end is hung on the pin 33 so that the tape holder always keeps the tape 22 on the tape conveying surface. 31 is pressed.

The operation of the component supply device configured as described above will be explained below.

As shown in FIG. 4, the tape 22 moves linearly forward intermittently from the previously set state to the parts take-out position 26 by rotating the wheel 28 one pitch at a time so that the parts arrive one after another. parts reel 19
Since it is rotatably attached to the pin 20, it becomes necessary to unwind the tape 22 while sequentially performing intermittent rotational movements (57, -7). The tape 22 is conveyed along the tape conveyance path 26, and is pressed against the tape presser 2 at a position immediately before the parts removal position 26.
Pressed to 3. This is done at the parts removal position 26.
This is to prevent the parts from shifting in position. The tape 22 is not restrained in the vertical direction from the reel holder 21 to the tape presser 23.

Still another conventional example will be explained below with reference to FIG.

The configuration and operation of the component supply device in FIG. 7 are almost the same as those in FIG. 4, so a description thereof will be omitted. The difference from FIG. 4 is that the tape presser 38 presses the tape 40 over the entire conveyance path 39.

Problems to be Solved by the Invention However, the two tape pressing methods described above have the following problems.

First, as shown in Fig. 4, if the tape is not restrained in the tape transport path until it reaches the component removal position, the tape exhibits unstable behavior with each pitch feed operation during this path, and the tape This may lead to deterioration of quality.

On the other hand, as shown in FIG. 7, the method of pressing the tape over the entire tape transport path increases friction during pitch feeding, which is considered undesirable in terms of tape quality.

In view of the above problems, the present invention provides a component supply device that does not cause unstable behavior or unnecessary frictional force to the tape during the tape transport path.

Means for Solving the Problems In order to solve the above problems, the parts supply device of the present invention includes:
The tape being conveyed from the reel holder section is provided with at least two or more tape pressing sections in the tape conveyance path until the tape is taken out from the tape.

Function The present invention is effective in protecting the quality of the tape because the above-described configuration allows the tape to be conveyed without applying unnecessary friction to the tape by pressing the tape onto the conveying path surface.

Embodiment γ7.7 A component supply device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a parts supply device in an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a tape conveyance path section, and 2 a plate fixed to the tape conveyance path 1. As shown in FIG. 3 is the parts reel, 4 is the pin and parts reel 3
is held freely rotatable. A reel holder 5 fixes the pin 4 and is also fixed to the tape conveyance path 1.

Reference numeral 6 denotes a tape pressing section added in the conveyance path, which presses the tape 7 between it and the tape conveyance path 1. The detailed structure of the tape holding part 6 is the same as that of the conventional example shown in FIG. 5, so the explanation will be omitted. Reference numeral 8 denotes a tape pressing portion, which is the same as 6, but presses the tape 7 immediately before the component removal position 9, as in the conventional case.

1o is a pin, and 11 is a wheel. The wheel 11 is engaged with the feed hole (see 37 in FIG. 6) of the tape γ, and its rotational action feeds the tape one pitch at a time.

The operation of the component supply apparatus constructed as described above will be explained below with reference to FIGS. 1 and 2.

FIG. 2 is a side view of FIG. 1, showing the tape feeding state. The tape 7 conveyed from the parts reel 3 to the tape conveyance path 1 first passes between the tape pressing part 6 and the conveyance path 1, and then the tape pressing the tape 7 at a position immediately before the chip take-out position 9. It passes through the holding part 8 and reaches the chip removal position 9. As shown in Figure 2, the interval β
In No. 1, the two tape pressers 6 and 8 are pressed by force, and the tape can be fed at a stable pitch. interval β
In step 2, the tape is not constrained in the vertical direction, but the section where the tape is not constrained is short or short, and unnecessary force is not easily applied to the tape.

As described above, according to this embodiment, by providing another tape holding part in the tape conveyance path from the reel holder part to the tape holding part immediately before the chip ejection position, the tape can be fed. This prevents unstable behavior of the tape at times and maintains the quality of the tape.

Effects of the Invention As described above, the present invention prevents unnecessary behavior from occurring in the tape by providing at least two tape holding parts in the process from the reel holder part to the position where chips from the tape are taken out. Furthermore, it is possible to convey the tape without applying unnecessary frictional force to the upper surface of the tape, which is effective in maintaining the quality of the tape.
