Description

Tape feeder

This invention relates to the tape feeder which supplies an electronic component to the pick-up position of a component mounting apparatus by pitch-feeding the component supply tape (henceforth simply a "tape") which supports an electronic component.

As a method of supplying an electronic component to the pick-up position of the nozzle of the transfer head in the component mounting apparatus, a method using a tape feeder is known. In this method, the tape supporting the electronic component is taken out from the supply reel, pitch-feeded in synchronization with the mounting timing of the electronic component, and supplied to the nozzle.

In such a tape feeder, when the tape drawn out from the supply reel is used up, a splicing operation of inserting the tape drawn out from the new supply reel and replacing it with a new tape is required.

As a splicing mechanism for this splicing operation, the present inventors developed the splicing mechanism using the tape press part PP so far as shown in FIG. In this splicing mechanism, the subsequent tape T2 is introduced into the tape feed path TR so as to overlap on the tape T1 currently being used, and the end thereof is positioned above the sprocket SP.

The tape pressing part PP is arrange | positioned above the sprocket SP, and the tape pressing part PP presses a tape by an elastic force. At this time, the teeth of the sprocket SP are engaged only with the hole portion of the tape T1 currently being used, and are not engaged with the hole portion of the subsequent tape T2. After that, when the rear end of the tape T1 currently in use passes through the sprocket SP, the subsequent tape T2 is pressed by the tape pressing part PP so that the hole of the subsequent tape T2 is provided in the teeth of the sprocket SP. To interlock.

However, in the splicing mechanism shown in FIG. 1, since the subsequent tape T2 is positioned directly above the sprocket SP in a state where the subsequent tape T2 is overlaid on the tape T1 currently being used, the subsequent tape T2 is present due to an imbalance in the tape thickness. There was a risk of being conveyed with the tape T1 in use, and there was a problem in the stability of the splicing operation.

On the other hand, Japanese Patent Laid-Open No. 2010-147223 discloses a tape feeder having two tape introduction paths. According to the tape feeder of Japanese Laid-open Patent No. 2010-147223, a tape and a subsequent tape currently being used in a splicing operation are disclosed. The problem of transporting together does not occur. However, in the tape feeder of Japanese Patent Laid-Open No. 2010-147223, since the tape feeder such as a sprocket is arranged in each of two systems of tape introduction, the structure of the tape feeder becomes complicated, and the tape feeder becomes large and the manufacturing cost also increases.

According to an aspect of the present invention, a main problem is to provide a tape feeder capable of stably performing the splicing operation with a simple configuration.

Tape position shifting means for moving.

Since the tape feeder according to one aspect of the present invention has a first tape introduction path and a second tape introduction path as a tape introduction path for introducing the tape into the tape delivery path leading to the pick-up position, the tape feeder is currently used. The standby position of the path and subsequent tapes can be completely separated. Therefore, there is no problem that the current tape and the subsequent tape are transported together in the splicing operation so that the splicing operation can be stably performed.

In addition, since the tape feeder according to one aspect of the present invention has a tape position shifting means for moving the tape conveyed in the first tape introduction path to the second tape introduction path, the tape feed means has a first tape introduction path side. Splicing can be performed even if it is placed only in. That is, since the tape conveying means does not need to be arranged on the side of the second tape introduction path, the overall configuration can be simplified and the size of the apparatus can be reduced and the cost can be reduced.

Hereinafter, with reference to FIGS. 5-9B, the detailed structure of the part of the 1st tape introduction path 3 and the 2nd tape introduction path 4 is demonstrated.

Fig. 5 is a detailed configuration diagram showing a portion of the tape feeder shown in Fig. 2 by introduction of the tape, and Fig. 6 is a view showing the front support plate of the pair of support plates removed from the tape feeder shown in Fig. 5. It is a figure which shows the state. FIG. 7 is a perspective view of a main part having a cross section taken along line AA of FIG. 5, and FIG. 8 is a cross-sectional view taken along line BB of FIG. 5, and FIGS. 9A and 9B are cross-sectional views taken along line CC of FIG. 5. For the sake of explanation, the tape to the first tape introduction is also shown.

The first tape introduction passage 3 is formed by a pair of support plates 15 which are arranged to sandwich the second sprocket 8. Specifically, as shown in Fig. 7, the pair of support pieces 15a (see Figs. 7 to 9B) protrude inwards from the lower ends of the opposing surfaces of the pair of support plates 15. One tape introduction path 3 is formed.

The pair of support plates 15 are arranged to face each other by connecting two upper portions thereof with the pins 16, and there is no structure for fixing the lower portion. Therefore, the spacing between the opposing surfaces of the pair of support plates 15 can be expanded and contracted.

Meanwhile, as shown in FIGS. 5 and 6, the second tape introduction passage 4 is formed below the first tape introduction passage 3, and the second tape introduction passage 3 is formed of the tape conveyed from the first tape introduction passage 3. Tape position switching means 17 for switching the position to the second tape introduction passage 4 is disposed above the first tape introduction passage 3.

The tape position shifting means 17 comprises a lever member 17a rotatable about the rotation axis 18.

The coil spring 19 functions as an elastic means for applying an elastic force to the lever member 17a so that the lever member 17a returns to the initial position. Therefore, the lever member 17a is provided so that it may elastically press to the initial position above the 1st tape introduction path 3 (a pair of support pieces 15a) by the coil spring 19. As shown in FIG.

10 is a perspective view showing the tape position switching means 17 according to the present embodiment.

The lever member 17a constituting the tape position shifting means 17 includes a pair of projections 17b protruding from both sides in the longitudinal direction thereof.

V-shaped grooves 17c are formed on the upper surfaces of the pair of protrusions 17b, respectively. As shown in Figs. 5 and 8, the groove 17c is fitted to the lower end portions of the pair of support plates 15 when the lever member 17a is in the initial position. That is, the notches 15b are formed at the lower ends of the pair of support plates 15. When the lever member 17a is in the initial position, the grooves 17c of the protrusions 17b are fitted to the notches 15b. You lose.

Thus, when the lever member 17a is in the initial position, the gap G1 between the opposing surfaces of the pair of support plates 15 is coupled by the engagement of the notch 15b and the groove 17c of the protrusion 17b. The enlargement is prevented, and it is possible to prevent the tape T from falling from the first tape introduction path 3.

Moreover, although the protrusion part 17d is formed in the lever member 17a, the protrusion part 17d contains the 1st protrusion 17d_1 and the 2nd protrusion 17d_2.

The first protrusion 17d_1 is formed in one pair so as to protrude from both side surfaces in the longitudinal direction at the end side (right side in FIG. 10) of the lever member 17a, and the second protrusion 17d_2 is proximal to the lever member 17a. It is formed in one pair so as to protrude from both sides in the longitudinal direction on the (base) side (left in Fig. 10).

The pair of first protrusions 17d_1 and the pair of second protrusions 17d_2 have tapered surfaces 17d_11 and 17d_21, respectively.

As shown in FIGS. 5 and 9A, the pair of first protrusions 17d_1 includes a pair of support plates 15 including the tapered surface 17d_11 when the lever member 17a is in the initial position. It fits in a pair of through-hole 15c formed in (circle).

Similarly for the pair of second projections 17d_2, the pair including the tapered surface 17d_21 when the lever member 17a is in the initial position has a pair of through holes 15d formed in the pair of support plates 15. )

Although the through

holes

15c and 15d according to the present embodiment are formed in the shape of holes, the present invention is not limited thereto. That is, according to the present invention, recesses for fitting the tapered surfaces 17d_11 and 17d_21 may be formed in the support plate 15 instead of the through holes.

On the other hand, the lever press part 17e is formed in the edge part of the lever member 17a. The user can move the lever member 17a downward by pressing the lever pressing portion 17e.

On the other hand, the 2nd tape stage detection sensor 20 is arrange | positioned in the vicinity of the 2nd sprocket 8 among the parts of the 1st tape introduction path 3, as shown to FIG. 5 and FIG.

The second tape end detection sensor 20 is a mechanical sensor using the sensor lever 20a similarly to the first tape end detection sensor 14 shown in FIG. 4, and the sensor lever 20a and the optical sensor element 20b. Equipped with.

The sensor lever 20a is provided so as to be rotatable by the rotation shaft 18 similarly to the tape position switching means 17.

One end of the sensor lever 20a is disposed to be positioned in the first tape introduction path 3 by the elastic pressing force of the coil spring 21, and the other end of the sensor lever 20a is a light emitting part and a light receiving part of the sensor element 20b. Located in between.

When the end of the tape T arrives at the position of one end of the sensor lever 20a, one end of the sensor lever 20a is lifted by the end of the tape T so that the sensor lever 20a is moved around the rotation axis 18. Rotate

As a result, the light from the light emitting portion of the sensor element 20b is received at the light receiving portion, the sensor element 20b is turned on, and the end of the tape T is detected. Detection information at the end of this tape T is transmitted to the control part 12 shown in FIG.

In addition, the 1st tape introduction part 3a of the 1st tape introduction path 3 consists of the inverted L-shaped flexible member 22, as shown in FIG. Specifically, the vertical plate part 22a of the flexible member 22 is fixed to the tape feeder main body 1 (refer FIG. 2), and the horizontal plate part 22b comprises the 1st tape introduction part 3a. The 1st tape introduction part 3a which consists of this horizontal board part 22b can be displaced in the arrow direction of FIG.

In the above configuration, the tape T is first introduced from the first tape introduction portion 3a of the first tape introduction passage 3 and guided along the first tape introduction passage 3 and the tape transfer path 2. That is, the tape T is sent by the second sprocket 8 to the third sprocket 10, after which the second sprocket 8 is stopped and by the third sprocket 10 to the first sprocket 5. Is sent. Thereafter, the third sprocket 10 is stopped and the tape T is pitch-feeded by the pitch rotation of the first sprocket 5.

Then, the electronic component supported by the tape T is picked up by the nozzle of the transfer head (not shown) of the component mounting apparatus at the pick-up position P. As shown in FIG. In addition, the tape T is bonded (attached) to cover the component to protect the component and to prevent the falling off, which is a tape transfer between the third sprocket 10 and the first sprocket 5 It peels from the tape T by a well-known peeling mechanism (not shown) at the suitable position of the furnace 2. As shown in FIG.

Subsequent tapes are prepared while the tape T is in use, and a splicing operation of replacing the tapes is performed using the prepared subsequent tapes. 12A to 12D are explanatory diagrams showing the procedure of the splicing operation. 12A-12D, the tape currently in use is shown as T1 and the subsequent tape as T2 for illustration.

12A shows that the tape T1 currently in use is introduced from the first tape introduction portion 3a of the first tape introduction passage 3 in the manner described above, and thus the first tape introduction passage 3 and the tape transfer path 2 are provided. Shows the state guided along.

The subsequent tape is prepared while this tape T1 is used. First, as shown in FIG. 12B, the user moves (rotates) the lever member 17a constituting the tape position switching means 17 to thereby move the tape T1 conveyed from the first tape introduction path 3. ) Is moved to the second tape introduction path (4).

As shown in FIG. 7, the first tape introduction passage 3 includes a pair of protruding inwards from the lower end of the opposing surface of the pair of support plates 15 arranged so as to be able to expand and contract in an interval between the opposing surfaces. Since it is formed by the support piece 15a, by moving the lever member 17a downward (rotating) and pressing the tape T1, the tape T1 deviates from the 1st tape introduction path 3 and is 2nd. Move to the tape introduction path (4). That is, through this process, the tape introduction path for introducing the tape T1 into the tape transfer path 2 is switched from the first tape introduction path 3 to the second tape introduction path 4.

In the step before this switching, the tape T1 was introduced into the tape feeder main body 1 from the first tape introduction portion 3a (see FIG. 2), but the first tape introduction portion 3a was introduced as shown in FIG. 11. Since it consists of the horizontal board part 22b of 22, when the tape T1 is pressed and it moves to the 2nd tape introduction path 4, the horizontal board part 22b is deformed in the arrow direction of FIG. Thereby, the tape introduction part of the tape T1 is also the 2nd tape introduction part 4a of the 2nd tape introduction path 4 side from the 1st tape introduction part 3a of the 1st tape introduction path 3 side (FIG. 2, FIG. 5). , See FIG. 6).

In addition, in the present embodiment, as shown in FIGS. 9A and 10, the portion including the tapered surface 17d_11 of the first protrusion 17d_1 and the second protrusion 17d_2 when the lever member 17a is in the initial position. The portion including the tapered surface 17d_21 is sandwiched between the through hole 15c and the through hole 15d (see Fig. 5) formed in the pair of support plates 15, respectively. Accordingly, when the lever member 17a is moved (rotated) downward in this initial state, the tapered surface 17d_11 moves along the opposite surface of the pair of support plates 15 as shown in FIG. 9B. Similarly, when the lever member 17a moves (rotates) downward, the tapered surface 17d_21 also moves along the opposite surface of the pair of support plates 15. Then, the space | interval between the opposing surfaces of a pair of support plate 15 expands from G1 to G2.

That is, in the case of the first projection 17d_1 of the lever member 17a, since the maximum width L1 of the cross section is larger than the interval G1, when the lever member 17a moves downward, the pair of support plates 15 The spacing between the opposing surfaces becomes large. Therefore, before the lever member 17a moving downwards presses the tape T1 conveyed from the 1st tape introduction path 3, the space | interval between the opposing surfaces of the pair of support plates 15 is fully expanded beforehand. Even if the lever member 17a does not strongly press the tape T1, the tape T1 can be moved to the second tape introduction path 4, thereby preventing damage to the tape T1.

That is, the tape T1 having a width of W is pressurized and moved by the lever member 17a moving downward. When the lever member 17a moves downward, the tape T1 is moved before pressing the tape T1 in advance. The distance between the opposing surfaces of the pair of support plates 15 extends from G1 to G2. In this case, the distance between the support pieces 15a is also increased from S1 to S2 (where S1 <W and S2> W), whereby the tape T1 is freely moved downward, thereby damaging the tape T1. This will be prevented.

In this manner, the tape T1 moved to the second tape introduction path 4 is spaced apart from the second sprocket 8, but the tape T1 is the first sprocket 5 shown in FIG. Since it is in the state of meshing with, it continues to pitch-feed by the pitch rotation of the 1st sprocket 5.

The timing of moving the tape T1 to the second tape introduction path 4 by operating the lever member 17a is any time after the tape T1 is engaged with the third sprocket 10 shown in FIG. It is possible. After the third sprocket 10 is engaged with the third sprocket 10, even after the tape T1 is separated from the second sprocket 8, the first sprocket 5 is transferred to the tape feed path 2 by the rotation of the third sprocket 10. Pitch feed by

Although the operation of the lever member 17a according to the present embodiment is performed manually, the present invention is not limited thereto. That is, the operation of the lever member 17a according to the present invention may be performed automatically. For example, after detecting that the tape T1 is engaged with the third sprocket 10 from the encoder measurement value of the second motor 8 or the third motor 11 or the like, the lever member 17a is lowered by an actuator or the like. Direction (rotation) can be made.

After the tape T1 is moved to the second tape introduction path 4, the subsequent tape T2 is introduced into the first tape introduction path 3 as shown in Fig. 12C.

Specifically, the tape T2 is manually introduced from the first tape introduction portion 3a while the second sprocket 8 disposed in the first tape introduction passage 3 is rotated, and the tape T2 is secondly introduced. Engage the sprocket (8). When engaged with the second sprocket 8, the tape T2 is automatically conveyed by the second sprocket 8. When the end of the tape T2 is detected by the second tape end detection sensor 20 described above, the control unit 12 shown in FIG. 2 stops the second motor 9. Thereby, the tape T2 stops at the position of the 2nd tape end detection sensor 20, as shown in FIG. 12C, and waits until a splicing operation is performed.

In the splicing operation, the rear end of the tape T1 currently in use is detected by the first tape end detection sensor 14 described in FIG. 4, or the component end sensor of the tape T1 is described in FIG. 3. Detected by (13) or when both the rear end and the component end of the tape T1 are detected.

That is, when the rear end or the component end of the tape T1 currently being used is detected, the control unit 12 shown in FIG. 2 rotates the second motor 9. As a result, as shown in FIG. 12D, the subsequent tape T2 is transferred from the first tape introduction path 3, and subsequently reaches the tape transportation path 2 to switch the tape from the tape T1 to the tape T2. The splicing work is performed automatically. After that, the next splicing operation is performed by repeating the sequence of FIGS. 12A to 12D.

As described above, the tape feeder 100 according to the present embodiment has a first tape introduction passage 3 and a second tape introduction passage 4 as tape introduction passages, so that the tape transfer path and the standby of subsequent tapes are currently in use. The position can be completely separated. Therefore, the splicing operation can be stably performed without the problem that the tape currently being used and the subsequent tape are conveyed together.

Moreover, since the tape feeder 100 which concerns on this embodiment has the tape position switching means 17 for moving the tape conveyed from the 1st tape introduction path 3 to the 2nd tape introduction path 4, In the tape introduction path, the splicing operation can be performed by arranging the tape transfer means only on the first tape introduction path 3 side. That is, since the tape conveying means is not disposed on the second tape introduction passage 4 side, the configuration becomes simple, and the size and cost can be reduced.

Next, another embodiment of the present invention will be described.

Therefore, before the tape position switching means 17 (lever member 17a) presses the tape T conveyed along the support piece 15a, the tape position switching means 17 (lever member 17a) protrudes. By pressing the pieces 15e, the distance between the opposing surfaces of the pair of support plates 15 is enlarged.

Moreover, as shown in FIG. 13, when the contact surface of the protrusion 15e and the tape position switching means 17 (lever member 17a) is a taper surface, the space | interval between the opposing surfaces of a pair of support plates 15 Can be easily enlarged.

14 shows another embodiment. In this embodiment, the tapered surface 15a-1 is formed on the upper surface of the pair of support pieces 15a. Therefore, when the tape position switching means 17 (lever member 17a) moves downward and presses the tape T, the both ends of the tape T will contact the taper surface 15a-1, and a pair of support plates The distance between the opposing surfaces of (15) is enlarged.

In each embodiment described above, although the 1st tape introduction path 3 was formed with the pair of support piece 15a, it is not limited to this. For example, the 1st tape introduction path | route can also be formed only by one support piece 15a.

In the above embodiments, the protrusion 17b, the first protrusion 17d_1, the second protrusion 17d_2, the through

hole

15c, 15d, the protrusion 15e, and the tapered surfaces 17d_11 and 17d_21. Although the back is formed in one pair, the present invention is not limited to this and only one of the pairs may be formed instead of one.

Further, in the above embodiments, the second tape introduction passage 4 is formed below the first tape introduction passage 3, but the present invention is not limited thereto. That is, according to this invention, a 2nd tape introduction path can also be formed above the 1st tape introduction path. In this case, the tape can be moved from the first tape introduction path to the second tape introduction path by moving (rotating) the lever member constituting the tape position switching means.

While aspects of the present invention have been described with reference to the embodiments shown in the accompanying drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible from those skilled in the art. You will understand the point. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.
