The arm 15 is composed of a fixed arm 15a having one end attached to the base member 14, and a movable arm 15b provided on the other end of the fixed arm 15a so as to enable adjustment of the attachment position. The entire length of the arm 15 can be adjusted in accordance with the outer diameter dimension of the supply reel 19 rotatably provided to the support shaft 17 as described later. Moreover, the locking recessed part 16 is formed in the front-end | tip part of the said movable arm 15b.

The said support shaft 17 is provided with two or more said supply reels 19 in this embodiment. That is, each supply reel 19 is provided with a bearing 21 at a radially center portion, and the supply 21 is rotatably supported by inserting the bearing 21 on the support shaft 17 to the outside. It is.

As shown in FIG. 2, the support shaft 17 has a collar 22 between the two side surfaces of the supply reel 19 located at the center and the one side surface of the supply reel 19 located at both sides. The lower surface is mounted in contact with the end surface of the inner ring (not shown) of the bearing 21, and the other end surface of the two supply reels 19 located on both sides is provided with a fixing ring 23 on the end surface of the inner ring. It is mounted in contact with the end face of the.

As a result, the dancer lever 26 can be kept unstable. That is, the change in the relaxation length of the tape member 11 drawn out from the supply reel 19 is prevented.

In addition, the locking pin 30 is driven in the axial direction by a drive source such as a solenoid (not shown), so that the locking pin 30 is engaged with the coupling hole 29 when the solenoid is operated.

Each tape member 11 drawn out from the three supply reels 19 is guided by the first guide roller 31 and the second guide roller 32 constituting the guide means and guided to the cutting mechanism 33. do.

On the outer peripheral surfaces of the dancer roller 27 and the pair of guide rollers 31 and 32, guide grooves 34 having a trapezoidal cross-sectional shape are formed as shown in FIG. The bottom side of this guide groove 34 is set to the same width dimension as that of the tape member 11. As a result, the tape member 11 guided by the guide groove 34 and traveling is prevented from shifting in position in the width direction.

As shown in FIG. 7, the cutting mechanism 33 has a block member 35. The roller 36 (only one block member is shown) is rotatably attached to the edge part of the up-down direction of one side of this block member 35, respectively.

Each tape member 11 drawn out from the three supply reels 19 is guided by the pair of rollers 36 to travel along the side surface of the block member 35. At this time, the tape member 11 faces the inside of the release tape 4 facing the side surface of the block member 35, and the adhesive tape 3 faces the outside. Moreover, it is preferable to form also the said groove | channel 36 of the trapezoidal cross section which guides the tape member 11 in the said outer peripheral surface also in each said roller 36.

By the downward direction.

On the lower surface of the adhesive head 41, three elongate protrusions 41a protrude from each other at intervals corresponding to the three tape members 11. Therefore, when the adhesive head 41 is driven in the downward direction, the three elongated protrusions 41a allow the three adhesive tapes 3 to sandwich the release tapes 4 of the semiconductor cell 1. It is pressed on the upper surface. As a result, the adhesive tape 3 is adhered to the upper surface of the semiconductor cell 1. That is, three adhesive tapes 3 are simultaneously bonded to the upper surface of the semiconductor cell 1.

The remaining release tape 4 of the tape member 11 to which the adhesive tape 3 is attached to the semiconductor cell 1 is coupled to the roller 43a of the peeling roller unit 43. When this peeling roller unit 43 is driven in the direction shown by the arrow X in FIG. 1, the release tape 4 peels from the said adhesive tape 3.

The three release tapes 4 peeled from the said adhesive tape 3 pass between the pair of feed rollers 45 which made the outer peripheral surface roll-contact, respectively, and conveys the said release tape 4 by wind pressure to a conveyance direction. It passes through the air duct 46 which guides. At least one of the pair of feed rollers 45 is rotationally driven by a drive source (not shown). This conveyance roller 45 may be provided separately corresponding to each of the some release tape 4, and may be comprised so that the some release tape 4 may be interposed and collectively conveyed.

When the release tape 4 is peeled from the adhesive tape 3 adhered to the semiconductor cell 1, the release tape 4 is transferred in the direction of the arrow by a pair of feed rollers 45 in contact with each other. Thereby, the new adhesive tape 3 cut | disconnected by predetermined length is located in the upper side of the semiconductor cell 1 positioned in the predetermined position, and the above-mentioned adhesion | attachment operation is performed repeatedly.

The ultrasonic tool 74 is attached to the horn 76 which is ultrasonically vibrated by the ultrasonic vibrator 75, and the horn 76 is attached to and fixed to the other side of the main body 67, as described later. It is a structure that can be floated, that is, a structure that can swing. The front end surface of the said ultrasonic tool 74 is located opposite the end surface in which the convex part 66a of the support member 66 provided in the said 2nd attachment plate 64 was formed.

Thereby, the said 1st attachment plate 63 is driven by the said 1st linear drive source 61, The 1st, 2nd guide roller 31 of the said tape member 11 is carried out in the positioning groove 68. When the second mounting plate 64 is driven in the forward direction by the second linear drive source 62 in a state where the portions between the 32 are coupled, the supporting member 66 is attached to the front end surface of the ultrasonic tool 74. The convex part 66a of the end surface of () is press-contacted.

As a result, the release tape 4 of the new tape member 11 is ultrasonically bonded to the release tape 4 of the tape member 11 in use as described later.

Insertion through holes 77 are formed at four corners of the main body portion 67, and each of the through holes 77 is provided with a mounting bolt 78 standing up and installed on the first attachment plate 63. Inserted through Each attachment bolt 78 is equipped with a spring 79 as an elastic member that elastically supports the main body portion 67, and a nut is provided at the tip portion protruding from the insertion hole 77 of the bolt 78. 81 is screwed in.

As a result, the main body portions 67 of the three connection units 65 include three tape members 11 in which the positioning grooves 68 of the respective main body portions 67 are drawn out from the three supply reels 19. It is elastically displaceable to the said 1st attachment plate 63 so that it may become the same space | interval.

Of the protruding surfaces 67a divided into two of the main body portions 67, the ultrasonic tool (with respect to the traveling direction of the tape member 11) on one end side than the portion where the distal end surface of the ultrasonic tool 74 is exposed. In the protruding surface 67a located upstream from 74, the cutting groove 82 orthogonal to the positioning groove 68 is formed to the same depth as the positioning groove 68. As shown in FIG. That is, the positioning grooves 68 of the three main body portions 67 are formed in one line.

As shown to Fig.9 (a), (b), the said cutter groove 82 is the disk shaped cutter 83 in which the blade 83a was formed in the outer peripheral surface which is one of the elements which comprise the said connection unit 65. The outer circumferential surface is elastically pressed against the bottom surface of the cutting groove 82 so as to be driven while rotating.

That is, the support shaft 84 is provided in the center of the cutter 83. The cutter 83 is inserted into the groove of the U-shaped holder 85, and the support shaft 84 is slidably supported by the elongated hole 86 formed in the holder 85. A compression spring 88 is provided between the support shaft 84 and the locking shaft 87 provided on both outer surfaces of the holder 85. As a result, the cutter 83 is elastically supported in the direction of protruding from the tip of the holder 85.

In the space portion 59 of the base 56 of the connecting device 55, the holder 85 is provided on the protruding surfaces 67a of the three main body portions 67 provided side by side as indicated by arrows in FIG. A reciprocating drive is performed by a third linear drive source (not shown) such as a cylinder along the formed cutting grooves 82.

Thereby, as mentioned later, the said tape member 11 respectively positioned in the positioning groove 68 of the said three main-body parts 67 is driven by the said cutter 83 which drives along the said cutting groove 82. As shown in FIG. It is intended to be cut.

Next, operation | movement of the bonding apparatus of the said structure is demonstrated, referring FIG. 1, FIG. 11, and FIG.

Usually, the said adhesion | attachment apparatus performs the operation | work which adhere | attaches the some (3 in this embodiment) adhesive tape 3 cut | disconnected to the semiconductor cell 1 by predetermined length.

That is, the tape member 11 withdrawn from the three supply reels 19 supported by the support body 13 of the tape supply mechanism 12 is the 1st, 2nd guide rollers 31 and 32 of the connection unit 65. FIG. Guided in parallel with the adhesive head 41 by a pair of pass rollers 39 at the portion opposite to the adhesive head 41, passing through the detection unit 51 and the cutting mechanism 33. Then, it is sandwiched between the pair of feed rollers 45 and conveyed, and is conveyed in the discharge direction by the air duct 46 provided on the downstream side of the feed rollers 45 as much as it is conveyed.

Of the adhesive tape 3 and the release tape 4 which comprise the said tape member 11, only the adhesive tape 3 is cut | disconnected by the cutter 38 of the said cutting mechanism 33 to predetermined length. The cutting length of the adhesive tape 3 is set according to the length dimension of the semiconductor cell 1.

When the adhesive tape 3 of the three tape members 11 cut | disconnected by predetermined length is conveyed to the lower side of the said adhesive head 41, ie, the upper surface of the said semiconductor cell 1 positioned by the table 40, The semiconductor cell 1 is driven in the upward direction by the table 40 to a position where the upper surface thereof approaches the adhesive tape 3 cut into a predetermined length.

Subsequently, the adhesive head 41 is driven in the downward direction by the vertical drive source 42, and the three adhesive tapes 3 are sandwiched by the release tape 4 by the three elongated protrusions 41a. The upper surface of the semiconductor cell 1 is simultaneously pressed and bonded. After adhesion, the release roller unit 43 is driven in the direction indicated by the arrow X in FIG. 1, and the release tape 4 is peeled from the three adhesive tapes 3 adhered to the upper surface of the semiconductor cell 1.

When the release tape 4 is peeled off, the peeling roller unit 43 is driven in the direction opposite to the arrow X direction. At the same time, the feed roller 45 is driven, the tape member 11 is conveyed for a predetermined length, and the above-described bonding operation is repeatedly performed.

When the bonding operation is repeatedly performed, the tape member 11 wound around the three supply reels 19 provided on the support 13 decreases, and the remaining amount thereof becomes less than or equal to the predetermined amount. When the remaining amount of the tape member 11 is less than or equal to the predetermined value, the end portion of the tape member 11, that is, the portion where the adhesive tape 3 is not adhered to the release tape 4, is fed out from the supply reel 19. do.

The end portion of the release tape 4 to which the adhesive tape 3 is bonded is different from the portion to which the adhesive tape 3 is bonded and the amount of reflected light is drawn out from the supply reel 19. The first sensor 52 of the detection unit 51 is detected.

That is, when the remaining amount of the tape member 11 wound on at least one supply reel 19 among the three supply reels 19 provided in the support 13 is less than or equal to the predetermined value, the first portion of the detection unit 51 The sensor 52 will detect it.

By the detection signal from the 1st sensor 52 of the said detection part 51, the extraction | extraction of the tape member 11 from the three supply reels 19 by the said feed roller 45 is stopped. At the same time, a suction force is generated in the plurality of suction holes 35a formed in the side surface of the block member 35 of the cutting mechanism 33, so that the end portion of the tape member 11 is formed on the side surface of the block member 35. Adsorption is maintained.

Next, the first mounting plate 63 provided with the three connecting units 65 of the connecting device 55 is driven in the forward direction by the first linear drive source 61. Thereby, as shown to Fig.11 (a), (b), positioning of the terminal part 11E of the tape member 11 of each supply reel 19 whose cross section of the said connection unit 65 is trapezoid shape. Engaged in the groove 68, the tape member 11 is positioned so as not to shake in the width direction.

At the same time, as shown to Fig.11 (a), in the terminal part 11E of the said tape member 11, the part of the upstream side and the downstream side of the positioning groove 68 are the 1st suction hole ( 71 and 2nd suction hole 72, respectively, hold | maintain and hold | maintain. That is, the part corresponding to the side surface of the main body 67 of the said connection unit 65 in the said tape member 11 is hold | maintained by the side surface of this main body 67. FIG.

In this manner, when the end portion 11E of the tape member 11 is attracted and held on the side surface of the main body portion 67, the cutter 83 is driven by the third linear drive source as shown in Fig. 11B. Driven along the cutting grooves 82 formed in a row of the three main body portions 67, and in the terminal portion 11E of the tape member 11, the intersection with the cutting grooves 82 is the cutter ( 83).

The cutter 83 is supported by the holder 85 so as to be elastically displaceable. For this reason, when the cutter 83 enters the cutting groove 82, the blade 83a of the cutter 83 is held and positioned in the positioning groove 68 that intersects the cutting groove 82. It is elastically pressed against the tape member 11. For this reason, the part located in the cutting groove 82 in the tape member 11 can be reliably cut by the cutter 83. In addition, since the cutter 83 is elastically displaced, it is possible to prevent the blade 83a from coming into strong contact with the bottom surface of the cutting groove 82 to be damaged.

When the cutter 83 cuts the tape member 11 and returns to the original position, the portion upstream of the positioning groove 68 at the end 11E of the tape member 11 is held by suction. The suction force of the first suction hole 71 is turned off. Subsequently, the tape member 11 is tensioned by the weight of the dancer lever 26 so that the dancer lever 26 is rotated from the position indicated by the solid line in FIG. 1 to the position indicated by the dashed line, and then into the engaging hole 29. The locking pin 30 is driven and engaged by a drive source (not shown), and the dancer lever 26 is kept unrotable.

If the dancer lever 26 is held in a non-rotatable manner, from the locking recess 16 of the support 13, the support shaft 17 to which the three supply reels 19 are attached is detached, and a predetermined amount of tape The member 11 is replaced with a wound new supply reel 19. FIG. 12A shows the end 11E of the tape member 11 drawn out from the previous supply reel 19 remaining in the main body 67 by separating the support shaft 17.

The replacement of the supply reel 19 is performed by mounting the support shaft 17 with three new supply reels 19 attached to the support 13 or separating the support reel 19 from the support 13. After removing the old supply reel 19 after use and attaching a new supply reel 19 to the support shaft 17, the support shaft 17 is attached to the locking recess of the support 13. It may be any of those attached to 16).

If a new supply reel 19 is attached to the support 13, the tape member 11 wound around each supply reel 19 is taken out, and as shown in FIG. 12B, the new tape member 11 is attached. 11F of front end parts are adsorb | sucked to the 1st suction hole 71 of the main-body part 67 of the said connection unit 65, and the part by which the front end side was cut | disconnected at the location of the said cutting groove 82 more than that before It overlaps with the terminal end 11E of the tape member 11. That is, on the front end surface of the said ultrasonic tool 74, the starting end part 11F of the new tape member 11 overlaps with the rear end part 11E of the previous tape member 11.

In this manner, if the end portion 11E of the previous tape member 11 and the start end portion 11F of the new tape member 11 are superimposed, the three supporting members 66 correspond to the connection unit 65. The 2nd mounting plate 64 with which is provided is driven by a 2nd linear drive source 62 in a forward direction. At the same time, the ultrasonic vibrator 75 provided with the ultrasonic tool 74 is oscillated.

Thereby, as shown in FIG.12 (c), the convex part 66a of the end surface of the three support members 66 provided in the said 2nd attachment plate 64 is made into the said 1st attachment plate 63. As shown in FIG. The end portion 11E of the previous tape member 11 superposed on the front end surface of the ultrasonic vibrating ultrasonic tool 74 of the three connecting units 65 installed in the end portion, and the first end portion 11F of the new tape member 11. Since the pressure is pressed, the end portion 11E and the start end portion 11F of each tape member 11 are welded.

In this way, when welding the end portion 11E and the start end portion 11F of each tape member 11, the main body portion 67 of the connection unit 65 having the ultrasonic tool 74 is the first portion. The attachment plate 63 is held elastically displaceable by the spring 79. In addition, the attachment bolt 78 provided in the first attachment plate 63 is inserted through the insertion hole 77 formed in the four corners of the main body 67 in a rattling state.

For this reason, the front end surface of the ultrasonic tool 74 of the said main-body part 67 provided in the said 1st attachment plate 63 is between the terminal part 11E of the each tape member 11, and the starting end part 11F. When the main body 67 is pressed by the convex portion 66a of the supporting member 66 installed on the second attachment plate 64, the front end surface of the ultrasonic tool 74 is supported by the supporting member ( The spring 79 is elastically displaced while compressing the spring 79 so that the convex portion 66a of the 66 is formed.

That is, the front end surface of the ultrasonic tool 74 is elastically displaced so as to be parallel to the convex portion 66a of the supporting member 66. Therefore, in the front end surface of the said ultrasonic tool 74, the terminal end 11E and the starting end 11F of each superimposed tape member 11 are welded reliably.

In this manner, when the end portion 11E and the start end portion 11F of each tape member 11 are welded, the second mounting plate 64 is driven in the retraction direction, and then the swing of the dancer lever 26 is prevented. The locking pin 30 that is blocked is driven in the retraction direction, so that the holding state of the dancer lever 26 is released.

Subsequently, the suction holding of the start end portion 11F of the new tape member 11 by the first suction hole 71 formed in the main body portion 67 of the connection unit 65 and the second suction hole 72 are performed. After the suction holding of the end portion 11E of the previous tape member 11 is released, the first mounting plate 63 is driven in the retraction direction by the first linear drive source 61. That is, the main body part 67 of the said connection unit 65 is spaced apart from the connection part of the termination part 11E of the previous tape member 11 connected, and the start end part 11F of the new tape member 11.

When the connection work between the end portion 11E and the start end 11F of each tape member 11 is finished, the suction hole 35a of the block member 35 of the cutting mechanism 33 of each tape member 11 is terminated. The suction force is released to free each tape 11. And the position where the connection part of each tape member 11 becomes downstream from the cutting mechanism 33, ie, the adhesive tape 3 of the new tape member 11, is the block member 35 of the said cutting mechanism 33 The tape member 11 is pulled out by the feed roller 45 to the position corresponding to. Thereby, the connection work of the edge part 11E of the previous tape of each tape member 11, and the start end part 11F of the new tape is complete | finished. In addition, resumption of adhesion is performed after the connection portion reaches the point beyond the feed roller 45.

As described above, the support shaft 17 provided with the three supply reels 19 was detachably supported by the support 13 of the tape supply mechanism 12. For this reason, of the three supply reels 19 hold | maintained by the support shaft 17, the tape member 11 which remain | survives in the at least 1 supply reel 19 becomes below a predetermined amount, and it is the agent of the detection part 51 If detected by one sensor 52, the three supply reels 19 provided on the support 13 can be replaced together with the support shaft 17 by a new supply reel 19 based on the detection. have.

That is, when the three supply reels 19 are installed on the support 13, the difference in the length of the tape member 11 wound on each supply reel 19 or the tape member wound on each supply reel 19 ( Due to the difference in the usage amount of 11), the remaining amount of the tape member 11 wound around each supply reel 19 may not be constant. For this reason, a difference arises in the replacement timing of the three supply reels 19. FIG.

However, it was detected by the first sensor 52 of the detection unit 51 that the remaining amount of the tape member 11 wound on the at least one supply reel 19 among the three supply reels 19 became less than or equal to the predetermined value. At the same time, three supply reels 19 were exchanged at once.

For this reason, since the replacement operation of the multiple times performed once may be sufficient, the replacement operation of the supply reel 19 can be made easy and efficient.

By the way, since the remaining amount of the tape member 11 wound around each supply reel 19 may not become constant as mentioned above, when the several supply reel 19 is replaced collectively, the unused tape member (11) may occur. However, the length of the unused tape member is very short, and the replacement operation is repeated at short intervals for this short length, so rather than stopping the device at each time, it is better to give up some unused parts. This leads to cost savings.

In addition, the connection device 55 is provided with three connection units 65 on the first mounting plate 63 and the three support members 66 on the second mounting plate 64 as described above. It installs corresponding to the connection unit 65. FIG.

Therefore, the end portions 11E of the three tape members 11 of the previous three supply reels 19 and the start ends 11F of the three tape members 11 of the three new supply reels 19 are removed. Since the connection can be performed at the same time, the connection work of the three tape members 11 can be performed once, similarly to the replacement work of the supply reel 19. That is, it becomes possible to perform the connection work of the tape member 11 efficiently.

When connecting the end portion of the previous tape member 11 and the start end portion of the new tape member 11, the end portion 11E of the previous tape member 11 has a positioning groove 68 and a second having a trapezoidal cross section. The guide grooves 34 of the guide rollers 32 are held so as not to be shaken in the width direction, and the end portions 11F of the new tape member 11 are similarly guide grooves of the first guide rollers 31 having a trapezoidal cross section. It is held so as not to shake in the width direction by the 34 and the positioning groove 68.

Further, the end portion 11E of the previous tape member 11 is adsorbed and held by the first suction hole 71 formed in the main body portion 67, and the first end portion 11F of the new tape member 11 is secondly held. The suction hole 72 holds the suction hole.

For this reason, welding is carried out so that the end part 11E of the previous tape member 11 and the start end part 11F of the new tape member 11 which were positioned so that they may overlap on the front end surface of the ultrasonic tool 74 may not be shifted. can do. In addition, at the time of welding, the overlapping part in the said tape member 11 is pressed by the some convex part 66a formed in the end surface of the support member 66, and the front end surface of the ultrasonic tool 74 is supported. Since it elastically displaces so that the convex part 66a of the member 66 may be parallel to the formed end surface, the overlapping part in the said tape member 11 can also be reliably welded by this.

The end portion 11E of the previous tape member 11 held in the positioning groove 68 is cut by the cutter 83 traveling through the cutting groove 82 formed to intersect the positioning groove 68. I'm trying to. The bottom face of the positioning groove 68 and the cutting groove 82 is formed at the same height.

For this reason, since the tape member 11 hold | maintained at the bottom surface of the said positioning groove 68 rose by the thickness of the tape member 11 rather than the bottom surface of the said cutting groove 82, the said tape member 11 Is reliably cut by the cutter 83 traveling along the cutting groove 82 at a portion that intersects the cutting groove 82.

In addition, although the width dimension of the tape member 11 to be joined is very narrow about 1 mm, it connects by ultrasonic bonding, for example, to another connection method which connects using the tape for a connection, for example. On the other hand, it can also join in high strength in a short time.

13 is a front view of a connecting device 55 showing another embodiment of the present invention. In this embodiment, the plate-shaped rocking member 91 comes in contact with one side of the main body portion 67 of the connecting unit 65 on the side opposite to the surface on which the protruding surface 67a is formed, that is, the other side. have.

The oscillation member 91 is formed with a large diameter hole 92 larger than the outer diameter of the attachment bolt 78 in a portion corresponding to the attachment bolt 78 that is mounted on the first attachment plate 63. The nut 81 is screwed to the distal end of the attachment bolt 78 by passing the distal end portion through the large diameter hole 92 and the insertion through hole 77 of the main body portion 67.

Thereby, the rocking member 91 is elastically pressed and held by the spring 79 attached to the attachment bolt 78 on the other side of the main body portion 67. The horn 76 provided with the ultrasonic tool 74 is attached to the rocking member 91.

According to this structure, when the ultrasonic tool 74 is pressed by the supporting member 66 with the release tape 4 interposed therebetween, in order to bond the release tape 4 of the tape member 11, The ultrasonic tool 74 swings together with the rocking member 91 along the supporting member 66.

That is, when the ultrasonic tool 74 swings along the supporting member 66, the main body 67 ends without swinging. For this reason, when the said ultrasonic tool 74 is pressed by the said support member 66, since it rocked easily and follows the said support member 66, it becomes possible to reliably bond the said release tape 4. .

In the above-mentioned embodiment, an example in which two adjacent semiconductor cells are connected by three lead wires has been described. However, two or four or more lead wires may be connected. In this case, a plurality of supply lines corresponding to the number of lead wires may be used. What is necessary is just to install a reel to the support body of a tape supply mechanism.

In addition, the number of connection units provided on the first mounting plate and the supporting member provided on the second mounting plate may be a plurality corresponding to the number of supply reels provided on the support.

In addition, in embodiment mentioned above, the remaining amount of the tape member 11 wound by each supply reel 19 is not necessarily the same. For this reason, even if one tape member 11 reaches the end, the other tape member 11 may not reach the end. As described above, the end portion of the tape member 11 is configured only of the release tape 4 to which the adhesive tape 3 is not bonded.

Therefore, when each tape member 11 is cut simultaneously and the several supply reel 19 is replaced collectively, the tape member 11 which reached | attained the terminal part is cut | disconnected in the part of the release tape 4, The release tape 4 at the beginning of the replaced new tape member 11 and the release tape 4 of the previous tape member 11 are ultrasonically bonded.

On the other hand, in the tape member 11 which has not reached the end, it is cut in the position which the adhesive tape 3 adhere | attached. Therefore, the release tape 4 at the beginning of the replaced new tape member 11 and the adhesive tape 3 portion of the previous tape member 11 are ultrasonically bonded.

In the ultrasonic bonding, joining the release tape 4 of the new tape member 11 and the release tape 4 of the previous tape member 11 has little change in the tape thickness of the bonding portion, so that there is a risk of being caught on the conveyance path. Since the tapes are less bonded to each other, or because the release tapes of the same material are bonded to each other, it is not necessary to change the bonding conditions to the bonding of the release tape and the adhesive tape so that the tape member can be made constant. In this regard, it is preferable that the feed rollers 45 are individually driven to rotate so that they are fed out until the release tape 4 appears and cut at once.

In addition, the end part is not necessarily only in the release tape 4, but there may exist the tape member 11 of the kind in which the adhesive tape 3 is formed to the end part. The tape member 11 has an end mark (for example, a member having a different reflectance from that of the adhesive tape 3 as in the case of silver paper) attached to the surface of the adhesive tape 3 in the vicinity of the terminal portion, and having a first surface. It can be detected by the sensor 52. Also in this case, it is preferable to send out until the end mark appears by cutting the feed roller 45 individually about the previous tape member 11 which has not reached the end, and to cut them all together.

In this case, the upper surface of the adhesive tape 3 at the start end 11F of the new tape member 11 is pressed by the supporting member 66, and the adhesive tape 3 is applied to the surface of the supporting member 66. ) May adhere to the surface of the support member 66, or it is preferable to perform an anti-sticking treatment or to release the release tape.

In addition, there is no adhesive tape 3 at the start end and the end, and the tape member 11 to which the release tape 4 is exposed, and the tape member 11 provided with the adhesive tape 3 to the start end and the end. May be mixed, but when all of the reels are replaced, the previous tape member 11 may be sent forward until the end portion is detected, and the cut may be always performed in the vicinity of the end portion.
