Abstract

A carrier tape (1) is taken up by a carrier tape take up reel (7) without generating positional shift, even when the carrier tape whereupon an electronic component (12) is mounted by a mounting section (8) is shifted in a width direction, by taking up a spacer tape (4b) with the carrier tape after such shift is eliminated. A spacer tape guide roller (15d) which can set a position change permits the take up position of the spacer tape, which is taken up by the carrier tape take up reel and press-holds the carrier tape, to be in downstream of a carrier tape take up position in a take up direction.

Specification

Electronic component mounting apparatus and mounting method

Technical field

TECHNICAL FIELD [0001] The present invention relates to an electronic component mounting apparatus and mounting method for mounting an electronic component on a carrier tape fed out of a carrier tape supply reel force and winding the carrier tape together with a spacer tape on a carrier tape take-up reel.

Background art

[0002] For example, in TAB (Tape Automated Bonding) and COF (Chip On Film), an electronic component such as a semiconductor chip is mounted on a terminal portion formed on a film-like carrier tape.

FIG. 6 shows a conventional mounting apparatus for mounting electronic components on the carrier tape.

This mounting apparatus has a carrier tape supply reel 2 around which a carrier tape 1 is wound. As shown in FIG. 7, the carrier tape 1 is formed with a terminal 3 having a device hole 3a and a lead 3b provided with one end protruding from the device hole 3a. Therefore, the carrier tape 1 is wound around the carrier tape supply reel 2 so as to overlap the spacer tape 4a protecting the lead 3b of the terminal portion 3.

[0004] The carrier tape 1 fed out from the carrier tape supply reel 2 engages with the carrier tape guide roller 5a and is guided to the transport rail 6, and is taken up from the transport rail 6 onto the carrier tape winding reel 7. It is done. A mounting portion 8 is provided in the middle of the transport rail 6.

[0005] The carrier tape 1 is fed out from the carrier tape supply reel 2 so that a slack is generated between the carrier tape guide roller 5a and one end of the transport rail 6. The amount of sag of the carrier tape 1 is detected and controlled by the first lower sensor 11a and the first upper sensor l ib. That is, when the first lower sensor 11a detects the sagging carrier tape 1, the feeding of the carrier tape 1 by the carrier tape supply reel 2 is stopped. When the carrier tape 1 is no longer slack and no carrier tape 1 is detected by the first upper sensor l ib, the carrier tape 1 is fed by the carrier tape supply reel 2. Is issued. Thereby, the amount of sag of the carrier tape 1 is controlled within a predetermined range.

In the mounting portion 8, an electronic component 12 such as a semiconductor chip is mounted on the carrier tape 1 as shown in FIG. The mounting unit 8 has a mounting stage 13 driven in the X and Y directions and a mounting tool 14 driven in the X, Y and Z directions.

[0007] The spacer tape 4a fed out together with the carrier tape 1 from the carrier tape supply reel 2 is guided by a pair of spacer tape guide rollers 15a and 15b and wound around the spacer tape scraping reel 16. Taken.

When the electronic component 12 is supplied onto the mounting stage 13, the mounting stage 13 is positioned below the terminal portion 3 of the carrier tape 1. Next, the mounting tool 14 is driven in the downward direction. Accordingly, the lead 3b of the terminal portion 3 is bent and connected to the bump 12a of the electronic component 12.

[0009] The carrier tape 1 on which the electronic component 12 is mounted is intermittently fed at a predetermined pitch by a feed mechanism such as a sprocket (not shown) provided to face the transport rail 6. The carrier tape 1 on which the electronic component 12 is mounted and fed by the feeding mechanism is overlapped with the spacer tape 4b supplied from the spacer tape supply reel 18, and is wound around the carrier tape take-up reel 7. Accordingly, the electronic component 12 mounted on the carrier tape 1 is protected by the spacer tape 4b.

[0010] The carrier tape 1 is guided by the carrier tape guide roller 5b and wound around the carrier tape winding reel 7. The spacer tape 4b is guided by the lower spacer tape guide roller 15c and the upper spacer tape guide roller 15d and is wound around the carrier tape take-up reel 7.

[0011] When the electronic component 12 is mounted, the carrier tape 1 is intermittently fed at a predetermined length by a feed mechanism (not shown). On the winding side, the amount of sag of the carrier tape 1 intermittently fed is detected by the second lower sensor 17a and the second upper sensor 17b.

[0012] When the amount of sag becomes equal to or greater than a predetermined value and is detected by the second lower sensor 17a, the carrier tape take-up reel 7 is driven by the detection signal, and the carrier tape 1 and the spacer tape 4b Winding is started. When winding is started and the amount of sag is reduced and the second upper sensor 17b no longer detects the carrier tape 1, The scraping is stopped.

[0013] The carrier tape 1 and the spacer tape 4b are guided by the carrier tape guide roller 5b and the spacer tape guide roller 15d, respectively, so that the carrier tape 1 and the spacer tape 4b are wound around the carrier tape take-up reel 7. Position, that is, the outer peripheral surface of the winding core 7a of the carrier tape winding reel 7 or the winding surface when the tapes 1, 4b are wound around the carrier tape winding reel 7. The circumferential position in contact with the outer peripheral surface of the tapes 1 and 4b already wound around the core 7a is determined.

[0014] When the carrier tape 1 and the spacer tape 4b are already wound on the carrier tape take-up reel 7, the above winding position is the position where the carrier tape 1 is in contact with the already wound spacer tape 4b. In the case of the spacer tape 4b, the position is in contact with the already wound carrier tape 1.

[0015] Patent Document 1 shows a mounting apparatus having the above-described configuration!

Disclosure of the invention

[0016] As shown in FIG. 6, the conventional mounting apparatus is configured so that the carrier tape 1 and the spacer tape 4b have the same winding position Z at which the carrier tape 1 and the spacer tape 4b are wound around the carrier tape take-up reel 7. The roller 5b and the upper spacer tape guide roller 15d were positioned and provided. That is, the carrier tape guide roller 5b and the upper spacer tape guide roller 15d are arranged close to the lower side in the radial direction of the carrier tape take-up reel 7, thereby making the take-up position Z the same.

[0017] Recently, since a very thin carrier tape 1 is used, the carrier tape 1 may swing in the width direction during winding. If the carrier tape 1 is wound around the carrier tape take-up reel 7 while swinging in the width direction, the take-up may be shifted in the width direction of the carrier tape take-up reel 7.

[0018] If the take-up position Z of the carrier tape 1 and the spacer tape 4b with respect to the carrier tape take-up reel 7 is the same, the carrier tape 1 taken up on the carrier tape take-up reel 7 may be shaken in the width direction. Before the carrier tape 1 is fitted, that is, with the carrier tape 1 being displaced in the width direction, the carrier tape 1 is The reel is pressed and held on the outer peripheral surface of the take-up reel 7 and taken up.

[0019] Therefore, since the carrier tape 1 is wound around the carrier tape take-up reel 7 in a state of being shifted in the width direction, the amount of shift gradually increases and eventually exceeds the allowable range. There is.

[0020] According to the present invention, even when the carrier tape is swung in the width direction, the swing is reduced and the spacer tape is wound together with the carrier tape. It is an object of the present invention to provide a mounting apparatus and a mounting method that can be wound on a tape take-up reel.

That is, the present invention is a mounting device for mounting an electronic component on a carrier tape, and the carrier tape supply reel in which the carrier tape and the spacer tape are overlapped and wound,

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. The same parts as those of the conventional configuration shown in FIG.

As shown in FIG. 1, the mounting apparatus of the present invention has an upper spacer tape guide roller 15d for setting the winding position of the spacer tape 4b wound around the carrier tape winding reel 7. This upper spacer tape guide roller 15d It is arranged above the carrier tape guide roller 5b for guiding the carrier tape 1 wound around the take-up reel 7, and is provided so that the vertical positioning can be adjusted by the mounting member 21 as positioning means.

[0025] The attachment member 21 is in the form of a strip plate, and is arranged on the side of the carrier tape take-up reel 7 with the longitudinal direction along the vertical direction. As shown in FIG. 3, the attachment member 21 has a plurality of attachment holes 22 formed at predetermined intervals in the vertical direction. Then, the upper spacer tape guide roller 15d is attached and fixed to the attachment hole 22 at a predetermined position by the screw 23 via the washer 23a.

[0026] The upper spacer tape guide roller 15d is attached to the attachment member 21 and arranged above the carrier tape guide roller 5b, so that it is an outer peripheral surface of winding as shown in FIG. The winding position X of the spacer tape 4b with respect to the winding core 7a of the carrier tape winding reel 7 can be set downstream of the winding position Y of the carrier tape 1 in the winding direction.

[0027] In this way, the winding position X of the spacer tape 4b was shifted to the downstream side in the winding direction from the winding position Y of the carrier tape 1. Therefore, when the carrier tape take-up reel 7 is rotationally driven and the take-up starts, the carrier tape 1 comes into contact with the outer peripheral surface of the take-up, and when the carrier tape take-up reel 7 rotates by a predetermined angle, The spacer tape 4b is wound around the carrier tape 1 on the outer peripheral surface of the winding. That is, the spacer tape 4 b is wound around the carrier tape take-up reel 7 with a predetermined time delay from the carrier tape 1.

[0028] Therefore, even if the carrier tape 1 is wound around the carrier tape take-up reel 7 while swinging in the width direction, the spacer tape 4b presses and holds the carrier tape 1 after the carrier tape 1 swings out. It will be wound up. As a result, even if the carrier tape 1 swings during winding, it is possible to prevent the carrier tape 1 from being pressed and held in a state where the carrier tape 1 is displaced by the spacer tape 4b.

[0029] The amount of deflection of the carrier tape 1 when it is taken up by the carrier tape take-up reel 7 varies depending on the type of carrier tape 1 such as thickness, width dimension, material (particularly flexibility) or weight. come. [0030] If the amount of deflection of the carrier tape 1 varies depending on the type of product, the carrier tape 1 takes up from the carrier tape take-up reel 7 until the run-out stops and the carrier tape take-up reel 7 rotates. The angle is different.

Accordingly, when the type of the carrier tape 1 is changed, the mounting position of the upper spacer tape guide roller 15d with respect to the mounting member 21 is changed. As a result, the position where the spacer tape 4b is held by the carrier tape take-up reel 7 by pressing the spacer tape 4b, that is, the winding position X of the spacer tape 4b with respect to the carrier tape take-up reel 7, is set to the carrier. It can be changed downstream of the winding position Y of tape 1 in the winding direction.

[0032] For example, if the amount of run-out when the type of carrier tape 1 is changed to, for example, a soft one and the amount of runout increases, the winding position of the spacer tape 4b is set to the first position shown in FIG. Change to position XI downstream of winding position X.

Accordingly, the spacer tape 4b can press and hold the carrier tape 1 when the swing of the carrier tape 1 taken up by the carrier tape take-up reel 7 is settled.

[0034] When the carrier tape 1 is changed to, for example, a high-rigidity product and the runout amount is reduced, the winding position of the spacer tape 4b is set to the position X2 upstream from the initial winding position X. Change to

[0036] When the runout of the carrier tape 1 is small, it may be considered that the winding position of the spacer tape 4b is not set to X2, but remains XI on the downstream side of X2. In this case, the carrier tape 1 is not pressed and held by the spacer tape 4b when the deflection is settled at the winding position Y, but is pressed and held by the spacer tape 4b after being wound from X2 to XI. That's it.

[0037] Therefore, the rotation angle from when the carrier tape 1 is wound around the carrier tape take-up reel 7 until it is pressed and held by the spacer tape 4b increases. In addition, the carrier tape 1 may be displaced on the outer peripheral surface of the take-up core 7a of the take-up reel 7. Therefore, it is preferable that the carrier tape 1 is held by the spacer tape 4b when the run-out is stopped.

[0038] In other words, even if the amount of runout differs depending on the type of carrier tape 1, the upper spacer tape guide is used so that the spacer tape 4b presses and holds the carrier tape 1 when the runout has subsided. The mounting position of the roller l _5d with respect to the mounting member ₂₁ is set.

[0039] Accordingly, even when the magnitude of runout differs depending on the type of the carrier tape 1, it is possible to reliably prevent the carrier tape 1 from being displaced during scraping.

FIG. 4 is a second embodiment showing a modified example of the attachment member 21 which is a positioning means. In this embodiment, the attachment member 21 includes a plurality of members shown in the first embodiment. A long hole 25 is formed in place of the mounting hole 22, and the mounting position of the upper spacer tape guide roller 15 d can be changed along the long hole 25.

[0041] According to such a configuration, it is possible to set the mounting position of the upper spacer tape guide roller 15d steplessly.

FIG. 5 is a third embodiment showing still another modified example of the positioning means. In this embodiment, an upper spacer tape guide roller 15d is provided on the movable member 26. . The movable member 26 is provided so as to be movable along the linear guide 27. A screw shaft 28 is screwed onto the movable member 26, and the screw shaft 28 is rotationally driven by a motor 29.

Therefore, if the screw shaft 28 is rotationally driven by the motor 29, the movable member 26 can be moved along the linear guide 27. Therefore, the upper spacer tape guide roller _15d provided on the movable member 26. Can be set. That is, the winding position of the spacer tape 4b can be set.

In the third embodiment shown in FIG. 5, other driving means such as a cylinder or a linear motor may be used as the means for driving the movable member 26 instead of the screw shaft. Industrial applicability

According to the present invention, the spacer tape wound around the carrier tape take-up reel Since the winding position is set to the downstream side in the winding direction from the winding position of the carrier tape, the carrier tape is wound around the carrier tape winding reel, and the force is delayed to wind the spacer tape. For this reason, the spacer tape is wound after the carrier tape has settled, so that the carrier tape can be wound without any positional displacement.

In addition, the winding position of the spacer tape can be set. For this reason, even if the amount of runout varies depending on the quality of the carrier tape, the carrier tape can be reliably wound without slipping.
