The bus bar electrode 6a on the upper side and the bus bar electrode 6b on the lower side are respectively adhered to an adhesive tape 3 made of a conductive thermosetting resin, and are attached to the upper surface side of the adjacent one pair of the semiconductor elements 1. The adhesive tape 3 of the bus bar electrode 6a and the bus bar electrode 6b on the back side has one end portion of the lead wires 2a to 2n bent in a crank shape and is temporarily pressed against the other end portion.

Next, the leads 2a to 2n are pressurized and heated at a pressure greater than that at the time of the temporary pressure connection. Thereby, since the adhesive tape 3 is melt-hardened, the leads 2a to 2n are formally crimped, that is, connected and fixed to the upper surface of the semiconductor elements 1a to 1n.

Thereby, the plurality of semiconductor elements 1a to 1n are connected in a row by the leads 2a to 2n. The semiconductor elements 1a to 1n connected in a row by the leads 2a to 2n are referred to as a series 1A.

The adhesive tape 3 is attached to one side of the release tape, and the tape is formed by the adhesive tape 3 and the release tape. The belt member is wound around a supply reel that constitutes a supply device.

Setting up Three supply reels of the number of leads 2.

The belt member pulled out by the three supply spools is such that only the adhesive tape is cut by the cutting tape 3 and the release tape to correspond to the length dimension of the semiconductor element 1. Then, the adhesive tape is cut to a predetermined length, transported together with the release tape, and positioned opposite to the semiconductor element 1 positioned at the adhering position.

The abutting position is provided with a bonding head which is driven in the descending direction, whereby the adhesive tape cut into a predetermined length by the three tape members is pressed against the surface of the semiconductor element 1. Thereby, the adhesive tape cut into a predetermined length is attached to the surface of the semiconductor element 1.

After the adhesion, the release tape is peeled off by the adhesive tape attached to the semiconductor element 1. Next, after the peeling, the release tape is conveyed for a predetermined length, and the cutting of the adhesive tape is a part of the predetermined length and is attached to a substrate positioned under the adhesive position, and thus repeated.

When the continuation of such a work is continued, since the belt member wound around the supply reel of the supply device is used up, if the remaining amount is less than or equal to a predetermined value, the supply reel in use is replaced with a new supply reel.

The belt member pulled out by the supply spool is operated by a path guided by a plurality of flow rollers. Therefore, it is troublesome to arrange the belt member on the above-described path, that is, the belt member passage path.

Therefore, when the remaining amount of the belt member attached to the supply spool of the supply device is less than or equal to a predetermined value, this can be detected. Then, before the belt member is used up, the beginning end of the belt member of the new supply reel is connected to the end of the belt member of the supply reel in use by the supply reel in use. Ends.

Thereby, the belt member that is wound on the new supply reel is introduced into the path by the belt member of the supply reel in use.

The tape supply mechanism 12 has a support 13 as shown in Figs. 2 and 3 . The support body 13 is formed by a plate-shaped base member 14 in which the plate faces are arranged vertically, and a pair of arms 15 which are horizontally protruded from the both ends in the width direction of one side surface of the base member 14. The front end portion of the pair of arms 15 is formed with a locking recess 16 open to the upper surface, and one end of the support shaft 17 is detachably engaged with the other end portion to be supported by the locking recess portion 16.

Further, as shown in FIG. 7 and FIG. 8, the tape member 11 is adhered to one of the release tapes 4 made of a film-like resin, and is adhered to an adhesive tape 3 made of a conductive thermosetting resin. Composition.

The arm 15 is composed of a fixed arm 15a whose one end is attached to the base member 14 and a movable arm 15b which is provided at the other end of the fixed arm 15a at an adjustable mounting position, and the entire length of the arm 15 can be adapted as will be described later. The outer diameter of the supply spool 19 rotatably provided on the support shaft 17 is adjusted. Further, the locking recessed portion 16 is formed at an end portion of the movable arm 15b.

The support shaft 17 is provided with a plurality of the supply spools 19 which are three in the present embodiment. In other words, each of the supply reels 19 is provided with a bearing 21 at the center portion in the radial direction, and the bearing 21 is detachably fitted to the support shaft 17 to be rotatably supported.

As shown in Fig. 2, in the support shaft 17, the end faces of the collars 22 abut against the end faces of the inner rings (not shown) of the bearing 21, and are respectively mounted on both side faces of the supply spool 19 located at the center. One of the supply spools 19 on both sides Between the side faces, the fixing ring 23 abuts against the end surface of the inner ring and is attached to the other side surface of the two supply reels 19 on both sides.

The fixing ring 23 is screwed with the handle 24, and the handle 24 is rotated in the screwing direction, whereby the fixing ring 23 can be fixed to the support shaft 17.

Thereby, the three supply reels 19 attached to the support shaft 17 are positioned and fixed at predetermined intervals with respect to the support shaft 17 by the collar 22 and the fixing ring 23.

Next, when the support shaft 17 is detached from the locking recess 16 of the arm 15, and the pair of fixing rings 23 are removed by the support shaft 17, the three supply spools 19 can be detached from the support shaft 17. .

In other words, the three supply reels 19 can be attached and detached to the support shaft 17 at a time with respect to the support body 13. For example, if the supply reel 19 to be used is to be attached to the other support shafts 17, the exhausted supply is removed. After the spool 19, the three supply spools 19 that are not used can be attached to the support 13 at a time.

Further, although not shown, the friction motor provided to be rotationally driven is elastically pressure-bonded to the outer circumferential surface of the supply reel 19, and the supply reel 19 can be driven to rotate by the friction car. The friction car can also be driven to individually rotate the plurality of supply spools 19, or to drive a plurality of supply spools 19 to rotate in a batch.

Each of the supply spools 19 is wound with the above-described belt member 11. As shown in Fig. 1, the belt members 11 wound around the supply spools 19 are pulled out, and are respectively engaged with the swinging rollers 27 (only one of which is disclosed) rotatably provided at one end of the swinging lever 26.

The intermediate portion of the swing lever 26 in the longitudinal direction can be pivotally supported by the rocking shaft 28, and the slack length of the belt member 11 pulled by the supply spool 19 changes depending on the swing angle.

One end portion of the swing lever 26 is formed with an elongated engagement hole 29 along the longitudinal direction. When the swing lever 26 is pivoted to the position indicated by the chain line by the position shown by the solid line in FIG. 1, the locking pin 30 can be engaged with the engaging hole 29. Thereby, the swing lever 26 can be kept from being shaken. That is, it is possible to prevent the slack length of the above-described belt member 11 pulled out by the above-described supply spool 19 from changing.

Further, the locking pin 30 is driven in the axial direction by a driving source such as an electromagnetic coil (not shown), and is engaged with the engaging hole 29 when the electromagnetic ring is actuated.

Each of the belt members 11 pulled out by the three supply spools 19 is guided by the first guide roller 31 and the second guide roller 32 that constitute the guide mechanism, and guided to the cutting mechanism 33.

The outer circumferential surface of the oscillating roller 27 and the pair of guide rollers 31 and 32 is formed with a guide groove 34 having a trapezoidal cross-sectional shape as shown in FIG. The bottom edge of the guide groove 34 is set to have the same width dimension as that of the belt member 11 described above. Thereby, it is possible to prevent the above-described belt member 11 that is guided by the guide groove 34 from being displaced in the width direction.

As shown in FIG. 7, the above-described cutting mechanism 33 has a pulley member 35. A rotatable roller 36 (only one pulley material is shown) is attached to each of the corner portions at one of the upper and lower sides of the one side of the pulley member 35.

Each of the belt members 11 pulled out by the three supply spools 19 is one of the above Guided by the rollers 36, running along the sides of the pulley member 35 described above. At this time, the release tape 4 of the belt member 11 faces the inner side opposite to the side surface of the pulley member 35, and the adhesive tape 3 faces outward. Further, it is preferable that each of the rollers 36 is formed with a guide groove for guiding the belt member 11 and having a trapezoidal cross section on the outer peripheral surface.

A cutter 38 driven by a cylinder 37 is provided on the running surface side of the belt member 11 of the pulley member 35. The stroke of the cutter 38 is set such that the cutter 38 is driven by the cylinder 37, whereby only the adhesion of the release belt 4 attached to the belt member 11 is cut as shown in FIG. With 3.

At this time, in order to reliably cut the adhesive tape 3, it is preferable to cut the release tape 4 by about half of the thickness.

A plurality of suction holes 35a that communicate with the suction pump are formed on the side surface of the pulley member 35, and the belt member 11 is slidably held by the side surface of the pulley member 35 by the attraction of the suction hole 35a.

The three belt members 11 taken out from the three supply spools 19 are operated in parallel at a predetermined interval in a direction perpendicularly intersecting the paper surface of Fig. 1, and the cutting mechanism 33 has three cutters 38, and each cutter 38 It is arranged at intervals corresponding to the three strip members 11. Further, the three cutters 38 may be driven by one cylinder 37 or may be driven by different cylinders 37, mainly as long as the adhesive tapes 3 of the three belt members 11 can be cut at one time.

As shown in Fig. 1, the three strip members 11 that cut the adhesive tape 3 by the cutting mechanism 33 are attached to a guide trap (not shown) having a trapezoidal cross section formed on the outer peripheral surface of the plurality of flow rollers 39. The face of the adhesive tape 3 is guided downward in the direction indicated by the arrow in Fig. 1.

Then, the above three strip members 11 are guided, and the direction is X, The facing portions of the semiconductor element 1 as the substrate, which are positioned in the Y, Z and θ directions, are aligned with the semiconductor element 1 by the flow roller 39 and at predetermined intervals in the width direction of the semiconductor element 1. Separate runs.

When the portion cut to a predetermined length of the adhesive tape 3 by the cutting mechanism 33 is transported to a position facing the semiconductor element 1 that is positioned, the semiconductor element 1 is raised by the stage 40. After the direction is driven to a position close to the adhesive tape 3, the adhering head 41, which is disposed above the semiconductor element 1, as a bonding means, is driven in the descending direction by the vertical driving source 42.

Three ribs 41a are protruded from the lower surface of the above-mentioned sticking head 41 at intervals corresponding to the three belt members 11. Therefore, when the attaching head 41 is driven in the descending direction, the three adhesive strips 3 are pressed against the upper surface of the semiconductor element 1 via the release tape 4 by the three protrusions 41a. Thereby, the adhesive tape 3 is attached to the upper surface of the semiconductor element 1. That is, three adhesive tapes 3 are attached to the upper surface of the semiconductor element 1 at the same time.

The release tape 4 to which the adhesive tape 3 is attached to the tape member 11 of the semiconductor element 1 is engaged with the roller 43a of the peeling roller unit 43. When the peeling roller unit 43 is driven in the direction indicated by the arrow mark X in Fig. 1, the release tape 4 is peeled off by the above-mentioned adhesive tape 3.

The three release tapes 4 which are peeled off by the above-mentioned adhesive tape 3 are respectively transferred between the transfer rollers 45 by the outer peripheral surface, and the release tape 4 is guided by the air duct 46 guided by the wind pressure in the conveyance direction. At least one of the pair of transport rollers 45 is driven to rotate by a drive source (not shown). The conveying roller 45 can also correspond The individual stripping strips 4 are individually disposed, and the plurality of stripping strips 4 may be sandwiched and transported in batches.

When the release tape 4 is peeled off by the adhesive tape 3 attached to the semiconductor element 1, the transfer roller 45 is transferred by one of the transfer rollers 45 in the direction of the arrow. Thereby, the new adhesive tape 3 cut into a predetermined length is placed opposite to the semiconductor element 1 positioned at a predetermined position, and the above-mentioned pasting work is repeated.

In the path of the belt member 11, the detecting portion 51 as the detecting means is disposed on the upstream side of the cutting mechanism 33, and the detecting portion 51 detects the three supply spools supported by the support body 13 of the belt supply mechanism 12.

The terminal portion is detected by the difference in the amount of reflected light of the mold tape 4.

The second sensor 53 has a light projecting portion 53a and a light receiving portion 53b that are opposed to each other with the belt member 11 interposed therebetween, and detects whether or not the light emitted from the light projecting portion 53a is received by the light receiving portion 53b, that is, the light is projected. This is detected when there is no belt member 11 between the portion 53a and the light receiving portion 53b.

The first sensor 52 detects that the end portion of the tape member 11 is taken out, that is, when the end portion of the release tape 4 that is not attached to the adhesive tape 3 by the supply reel 19 is taken out, according to the detection signal thereof. The pulling operation of the belt member 11 by the above-described conveying roller 45 from each of the supply spools 19 is stopped.

In other words, the three first sensors 52 of the detecting unit 51 are provided to detect the end portions of the three strip members 11 taken out by the three supply reels 19, but at least one of the first sensing portions. When the end portion of the belt member 11 is detected, the pulling operation of the belt members 11 from the three supply spools 19 is simultaneously stopped.

In other words, the length of the belt member 11 previously wound around the three supply spools 19 or the amount of use of the belt members 11 of the supply spools 19 is different, and sometimes the respective first sensors 52 cannot simultaneously detect the belt members 11 Terminal department.

Even in such a case, since the remaining amount of the belt member 11 wound around the three supply spools 19 is greatly different, the end portion of the belt member 11 is detected by the first group of first sensors 52, and the stop can be stopped. The belt members 11 of the three supply spools 19 are pulled out.

At the same time as the pulling of the belt member 11 from the supply spool 19 is stopped, the suction hole 35a having an opening formed in the side surface of the pulley member 35 of the cutting mechanism 33 generates an attractive force, and the above-described detecting portion 51 is sucked and held by the belt member 11.

When the second mounting plate 64 is driven in the forward direction by the second linear drive source 62, the convex portion 66a of the end surface of the receiving member 66 is pressed against the front end surface of the ultrasonic tool 74.

Thereby, as will be described later, the release belt 4 of the new belt member 11 is ultrasonically joined to the release belt 4 of the belt member 11 in use.

The four corner portions of the main body portion 67 are provided with insertion holes 77, and the mounting bolts 78 that are erected on the first mounting plate 63 are inserted into the respective insertion holes 77 with a play. Each of the mounting bolts 78 is provided with a spring 79 as an elastic member that elastically supports the main body portion 67, and a nut 81 is screwed to the front end portion of the bolt 78 by the insertion hole 77.

Thereby, the main body portion 67 of the three connecting units 56 is elastically displaceably attached to the first mounting plate 63, and the positioning grooves 68 of the main body portions 67 become The three strip members 11 pulled out by the three supply spools 19 are equally spaced.

The protruding portion 67a of the main body portion 67 which is partitioned into two of the protruding surfaces 67a is located closer to the one end portion than the front end surface of the ultrasonic tool 74, that is, in the running direction with respect to the belt member 11, and is located upstream of the ultrasonic tool 74. The side protruding surface 67a and the cutting groove 82 perpendicularly intersecting the positioning groove 68 are formed at the same depth as the positioning groove 68. That is, the positioning grooves 68 of the three body portions 67 are formed in a line.

As shown in FIG. 9A and FIG. 9B, the cutting groove 82 is configured such that the outer peripheral surface of the disk-shaped cutter 83 which is one of the elements of the connecting unit 65 and has the blade 83a formed on the outer peripheral surface thereof is elastic. The ground pressure is connected to the bottom surface of the cutting groove 82, and is rotated and driven.

That is, the support shaft 84 is provided in the center part of the said cutter 83. The cutter 83 is inserted In the groove of the bracket 85 of the shape, the support shaft 84 is supported to be slidable in the long hole 86 formed in the bracket 85. A compression spring 88 is provided between the support shaft 84 and the locking shaft 87 provided on the outer sides of the bracket 85. Thereby, the cutter 83 is biased toward the direction in which the front end of the bracket 85 protrudes.

The bracket 85 is pressed by the cutting groove 82 of the protruding surface 67a of the three main body portions 67 which are formed in parallel with each other as shown by the arrow mark in Fig. 6 in the space portion 59 of the base 56 of the connecting device 55. The third linear drive source (not shown) such as a cylinder drives the shuttle back and forth.

Thereby, as will be described later, the belt members 11 respectively positioned in the positioning grooves 68 of the three main body portions 67 are cut by the cutter 83 driven along the cutting grooves 82.

Next, the operation of the above-described bonding device will be described with reference to Figs. 1, 11A, 11B, and 12A to 12C.

Usually, the above-described attaching device performs an operation of adhering the adhesive tape 3 which is cut into a predetermined length (three in the present embodiment) to the semiconductor element 1.

In other words, the belt member 11 pulled out by the three supply reels 19 supported by the support body 13 of the belt supply mechanism 12 is guided by the first and second guide rollers 31, 32 of the connection unit 65, passes through the detecting portion 51 and cuts. The blocking mechanism 33 is guided by the pair of conveying rollers 45 in parallel with the abutting head 41 in a portion opposed to the adhering head 41, and is conveyed by a pair of conveying rollers 45, and is conveyed. The air duct 46 provided on the downstream side of the conveying roller 45 is pressure-fed in the discharge direction.

Of the adhesive tape 3 and the release tape 4 constituting the belt member 11, only the adhesive tape 3 is cut by the cutter 38 of the cutting mechanism 33 to a predetermined length. The cut length of the adhesive tape 3 is set in accordance with the length dimension of the semiconductor element 1.

When the adhesive tape 3 cut into three strip members 11 of a predetermined length is conveyed under the above-mentioned attaching head 41, that is, above the semiconductor element 1 positioned via the stage 40, the semiconductor element 1 is used by the stage 40. It is driven in the ascending direction until it is close to the adhesive tape 3 cut to a predetermined length.

Next, the attaching head 41 is driven in the descending direction by the upper and lower driving sources 42, and the three adhesive strips 3 are passed through the release tape 4 while being pressed against the upper surface of the semiconductor element 1 by the three protruding strips 41a. After the adhesion, the peeling roller unit 43 is driven in the direction indicated by the arrow mark X in Fig. 1, and the release tape 4 is peeled off by the three adhesive tapes 3 which are attached to the upper surface of the semiconductor element 1.

When the release tape 4 is peeled off, the peeling roller unit 43 is driven in a direction opposite to the direction of the arrow X. At the same time, the conveying roller 45 is driven, and the belt member 11 is conveyed by a predetermined length, and the above-mentioned decoration work is repeated.

When the pasting work is repeated, the tape member 11 wound around the three supply reels 19 provided in the support body 13 is reduced, and the remaining amount is less than or equal to a predetermined value. When the remaining amount of the belt member 11 is less than or equal to a predetermined value, the end portion of the belt member 11, that is, the portion of the adhesive tape 3 to which the mold release tape 4 is not attached, is taken out by the supply spool 19.

The amount of reflected light of the portion of the release tape 4 taken out by the supply reel 19 that is not attached to the adhesive tape 3 and the portion where the adhesive tape 3 is adhered is different. Therefore, the first sensor 52 of the detecting portion 51 is It is detected that the part has been taken out.

In other words, in the three supply reels 19 provided in the support body 13, when the remaining amount of at least one of the belt members 11 wound on the supply reel 19 is less than or equal to a predetermined value, the first sensing of the detecting portion 51 The device 52 will detect this condition.

The conveyance roller 45 causes the conveyance roller 45 to stop the pulling of the belt member 11 from the three supply spools 19 based on the detection signal from the first sensor 52 of the detection unit 51. At the same time, the plurality of suction holes 35a formed on the side surface of the pulley member 35 of the cutting mechanism 33 generate an attraction force, and the end portion of the belt member 11 is sucked and held by the side surface of the pulley member 35.

Next, the first mounting plate 63 of the connecting device 55 provided with the three connecting units 65 is driven in the forward direction by the first linear drive source 61. Thereby, as shown in FIGS. 11A and 11B, the end portion 11E of the belt member 11 of each supply spool 19 The positioning groove 68 of the cross-sectional trapezoidal shape of the connecting unit 65 is engaged, and the belt member 11 is positioned so as not to vibrate in the width direction.

At the same time, as shown in FIG. 11A, the portion of the end portion 11E of the belt member 11 that is upstream of the positioning groove 68 and the portion on the downstream side are sucked and held by the first suction hole 71 and the second suction hole 72. . That is, a portion of the belt member 11 corresponding to the side surface of the main body portion 67 of the connecting unit 65 is sucked and held by the side surface of the main body portion 67.

As described above, when the end portion 11E of the belt member 11 is sucked and held by the side surface of the main body portion 67, as shown in FIG. 11B, the cutter 83 becomes a row along the three main body portions 67 by the third linear drive source. The cutting groove 82 is driven, and the end portion 11E of the belt member 11 is cut by the cutter 83 at a position where the cutting groove 82 intersects.

The cutter 83 is supported by the bracket 85 in an elastically displaceable manner. Therefore, when the cutter 83 enters the cutting groove 82, the blade 83a of the cutter 83 is elastically pressed against the belt member 11 positioned and held by the positioning groove 68 that intersects the cutting groove 82. Therefore, the portion of the cutting groove 82 of the belt member 11 can be reliably cut by the cutter 83. Further, by the elastic displacement of the cutter 83, it is possible to prevent the blade 83a from colliding too strongly against the bottom surface of the cutting groove 82 to be damaged.

When the cutter 83 cuts the belt member 11 and returns to the original position, the suction force of the first suction hole 71 that sucks and holds the portion of the end portion 11E of the belt member 11 that is upstream of the positioning groove 68 is closed. Next, the belt member 11 is stretched by the weight of the swing lever 26, and the swing lever 26 is rotated by a position shown by a solid line in FIG. 1 toward a position indicated by a chain line, and is driven by a driving source not shown. The locking pin 30 is driven to engage with the engaging hole 29, and the swing lever 26 is held so as not to be rotated.

When the swing lever 26 is held in a non-rotatable manner, the support shaft 17 to which the three supply spools 19 are attached is detached by the locking recess 16 of the support body 13, and replaced with a new one in which a predetermined amount of the belt member 11 is attached. The reel 19 is supplied. Fig. 12A shows the end portion 11E of the belt member 11 which is pulled out by the remaining supply reel 19 of the main body portion 67 by the detachment of the support shaft 17.

The supply spool 19 is replaced by a support shaft 13 to which a new three supply spools 19 are attached in advance, or a previous supply that has been removed from the support shaft 17 that has been removed by the support 13 The reel 19 is attached to the support shaft 17 of the new supply reel 19, and the support shaft 17 is attached to the locking recess 16 of the support body 13, either.

When the new supply spool 19 is attached to the support body 13, the belt member 11 wound around each of the supply spools 19 is pulled out, and as shown in Fig. 12B, the start end portion 11F of the new belt member 11 is sucked to the above-mentioned connection unit. The first suction hole 71 of the main body portion 67 of the 65 is overlapped with the portion of the front end portion 11E of the previous belt member 11 cut at the position of the cutting groove 82. That is, on the front end surface of the above-described ultrasonic tool 74, the end portion 11F of the new belt member 11 is overlapped at the end portion 11E of the old belt member 11.

When the end portion 11E of the old belt member 11 overlaps the start end portion 11F of the new belt member 11, the second mounting plate 64 of the three receiving members 66 corresponding to the connecting unit 65 is provided by the second linear driving source. 62 drives in the forward direction. At the same time, the ultrasonic vibrator 75 provided with the above ultrasonic tool 74 is oscillated.

As a result, as shown in FIG. 12C, the convex portion 66a provided on the end faces of the three receiving members 66 of the second mounting plate 64 is pressed against the three connecting units 65 provided in the first mounting plate 63 for super The end portion 11E of the old belt member 11 and the start end portion 11F of the new belt member 11 in which the ultrasonic vibration tool 74 of the ultrasonic vibration is overlapped with the front end portion 11F of the old belt member 11 are melted.

When the end portion 11E and the start end portion 11F of each of the belt members 11 are fused, the main body portion 67 of the connection unit 65 having the ultrasonic tool 74 is elastically displaced by the spring 79 to the first attachment plate 63. Further, the attachment bolts 78 provided on the first attachment plate 63 are inserted into the insertion holes 77 formed at the four corners of the main body portion 67 with a play.

Therefore, the end surface of the ultrasonic tool 74 provided in the main body portion 67 of the first mounting plate 63 passes through the end portion 11E and the start end portion 11F of each of the belt members 11 and is provided in the receiving member 66 of the second mounting plate 64. When the convex portion 66a is pressed, the main body portion 67 compresses the spring 79 and is elastically displaced, and the front end surface of the ultrasonic tool 74 follows the end surface of the convex portion 66a of the receiving member 66.

That is, the front end surface of the ultrasonic tool 74 is elastically displaced in parallel with respect to the convex portion 66a of the receiving member 66. Therefore, the end portion 11E and the start end portion 11F of the respective belt members 11 whose end faces overlap before the ultrasonic tool 74 are surely fused.

When the end portion 11E and the start end portion 11F of the respective belt members 11 are melted, after the second attachment plate 64 is driven in the backward direction, the locking pin 30 that blocks the swinging of the swing lever 26 is driven in the backward direction, and is released. Above pendulum The holding state of the moving rod 26.

Then, the first end portion 11F of the new belt member 11 provided in the first suction hole 71 of the main body portion 67 of the connecting unit 65 and the end portion 11E of the old belt member 11 which is carried by the second suction hole 72 are sucked. After the release is released, the first mounting plate 63 is driven in the reverse direction by the first linear drive source 61. That is, the body portion 67 of the above-described connecting unit 65 is separated from the connecting portion of the terminal portion 11E of the old band member 11 and the starting end portion 11F of the new belt member 11.

After the connection operation between the end portion 11E of each belt member 11 and the start end portion 11F is completed, the suction force of the suction hole 35a of the pulley member 35 of the cutting mechanism 33 of each belt member 11 is released, and the respective belts 11 are restored. Next, by the conveying roller 45, the position where the connecting portion of the belt member 11 to the belt member 11 is pulled out from the downstream side of the cutting mechanism 33, that is, the adhesive belt 3 of the new belt member 11 corresponds to the above-described cutting mechanism 33. The position of the pulley member 35. Thereby, the connection work of the end portion 11E of the old belt of each belt member 11 and the start end portion 11F of the new belt is completed. Furthermore, the re-starting of the affixing is performed only when the connecting portion reaches the conveying roller 45.

As described above, the support shaft 13 provided with the three supply spools 19 is detachably supported by the support body 13 of the tape supply mechanism 12. Therefore, at least one of the three supply and supply spools 19 held by the support shaft 17 is at least a predetermined amount or less, and if the first sensor 52 of the detection unit 51 detects the situation, According to the detection, the three supply reels 19 provided on the support body 13 and the support shaft 17 can be replaced with a new supply reel 19 at a time.

That is, when the three supply reels 19 are placed on the support 13, The residual amount of the belt member 11 wound around each of the supply spools 19 may vary due to the difference in the length of the belt members 11 wound around the supply spools 19 or the difference in the amount of use of the belt members 11 wound around the respective supply spools 19. Not the same. Therefore, the replacement period of the three supply reels 19 is different.

However, when the first sensor 52 of the detecting unit 51 detects that the remaining amount of at least one of the three supply spools 19 wound on the supply spool 19 is less than or equal to a predetermined value, the three supply spools 19 are replaced at a time. .

Therefore, the replacement work that has been performed in the past is completed once, so that the replacement work of the supply reel 19 can be facilitated and improved.

Further, as described above, the remaining amount of the belt member 11 wound around each of the supply spools 19 may be different. Therefore, when the plurality of supply spools 19 are replaced in batches, the unused belt members 11 are generated. However, the length of the tape member which is not used is only a little bit, and the replacement work is repeated at a slight interval for the length of the one point, so that each time the device is stopped, a part of the unused portion is discarded, and the cost can be reduced. .

Further, as described above, the connection device 55 is provided with three connection units 65 on the first attachment plate 63, and the three attachment members 66 are provided corresponding to the connection unit 65 on the second attachment plate 64.

Therefore, since the end portions 11E of the three belt members 11 of the old three supply spools 19 can be simultaneously connected to the start end portions 11F of the three belt members 11 of the new three supply spools 19, the supply spools 19 can be used. In the same manner as the replacement work, the connection work of the three belt members 11 is performed at one time. That is to say, the joining operation of the belt member 11 can be performed efficiently.

The end portion of the old belt member 11 and the beginning of the new belt member 11 When the portions are connected, the end portion 11E of the old belt member 11 is held by the positioning groove 68 having a trapezoidal cross section and the guide groove 34 of the second guide roller 32 so as not to deviate from the width direction, and the starting end portion 11F of the new belt member 11 is also the same. The guide groove 34 of the first guide roller 31 having a trapezoidal cross section and the positioning groove 68 are kept from being displaced from the width direction.

Further, the end portion 11E of the old belt member 11 is sucked and held by the first suction hole 71 formed in the main body portion 67, and the start end portion 11F of the new belt member 11 is sucked and held by the second suction hole 72.

Therefore, the end portion 11E of the old belt member 11 which is overlapped on the front end surface of the ultrasonic tool 74 by positioning and the start end portion 11F of the new belt member 11 are not eccentric and melted. Further, when fused, the overlapping portion of the belt member 11 is pressed by the plurality of convex portions 66a formed on the end faces of the receiving members 66, and the front end surface of the ultrasonic tool 74 is flatly formed along with the convex portion 66a where the receiving member 66 is formed. The end faces are elastically displaced, whereby the overlapping portions of the belt members 11 can be surely fused.

The end portion 11E of the old belt member 11 held by the positioning groove 68 is cut by the cutter 83 running on the cutting groove 82 formed by the positioning groove 68. The positioning groove 68 is formed at the same height as the bottom surface of the cutting groove 82.

Therefore, the belt member 11 held on the bottom surface of the positioning groove 68 is only divided by the thickness of the rising belt member 11 on the bottom surface of the cutting groove 82. Therefore, the belt member 11 is borrowed at a portion intersecting the cutting groove 82. The cutting machine 83 that runs along the cutting groove 82 is surely cut.

Further, the width of the joined belt member 11 is about 1 mm, and the size is very thin, and the connection is made by ultrasonic bonding, as compared with, for example, the use of a joint. By connecting other connection methods with a connection, it is possible to join at a high strength in a short time.

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

In the rocking member 91, a large diameter hole 92 having a larger outer diameter than the mounting bolt 78 is provided in a portion corresponding to the mounting bolt 78 that is erected on the first mounting plate 63, and the front end of the mounting bolt 78 is provided. The nut 81 is screwed to the distal end through the large diameter hole 92 and the insertion hole 77 of the main body portion 67.

Thereby, the rocking member 91 is elastically pressed and provided on the side surface of the main body portion 67 by the spring 79 attached to the mounting bolt 78. Next, a horn 76 provided with the above ultrasonic tool 74 is attached to the oscillating member 91.

According to this configuration, in order to engage the release tape 4 of the tape member 11, when the ultrasonic tool 74 is pressed by the receiving member 66 through the release tape 4, the ultrasonic tool 74 and the shaking member 91 accompany the receiving member 66. Shake together.

That is, when the ultrasonic tool 74 is rocked by the receiving member 66, the main body portion 67 may not be shaken. Therefore, when the ultrasonic tool 74 is pressed against the receiving member 66, the receiving member 66 is easily oscillated to follow the receiving member 66, so that the joining of the releasing belt 4 can be surely performed.

In the above embodiment, the three leads are connected adjacent to each other. The two semiconductor elements are described as an example. However, there are cases in which two or four or more leads are connected. In this case, a plurality of supply reels corresponding to the number of leads may be provided in the support of the tape supply mechanism.

Moreover, the number of the connection means provided in the first mounting plate or the receiving member provided in the second mounting plate may be plural in accordance with the number of supply reels provided on the support.

Further, in the above embodiment, the remaining amount of the belt member 11 wound around each of the supply spools 19 is not necessarily the same. Therefore, even if one belt member 11 reaches the terminal, there are other belt members 11 that do not reach the terminal. As described above, the end portion of the belt member 11 constitutes only the release belt 4 to which the adhesive tape 3 is not attached.

Therefore, when the respective belt members 11 are cut together, when the plurality of supply spools 19 are replaced in batches, in the belt member 11 reaching the terminal, the portion of the belt release belt 4 is cut, and the beginning of the new belt member 11 to be replaced is replaced. The release tape 4 is ultrasonically joined to the release tape 4 of the old tape member 11.

On the other hand, in the belt member 11 which has not reached the terminal, it is cut at the position where the adhesive tape 3 adhered. Therefore, the release tape 4 at the beginning of the replaced new belt member 11 is ultrasonically joined to the adhesive tape 3 of the old belt member 11.

In the ultrasonic bonding, the release tape 4 of the new belt member 11 and the release tape 4 of the old belt member 11 can reduce the thickness of the belt portion of the joint portion, and the risk caused by the conveyance path is small, or In order to bond between the release belts of the same material, the conditions for joining are constant, and it is not necessary to change due to the engagement of the release belt and the adhesive tape, so the old belt member 11 that has not reached the terminal should be individually The conveying conveyance roller 45 is rotated and sent out until the release belt 4 appears, and is cut off again.

Further, the terminal portion is not necessarily only the mold release tape 4, but also the tape member 11 of the type in which the adhesive tape 3 is formed to the end portion. The belt member 11 is attached to the surface of the adhesive tape 3 in the vicinity of the end portion, and has an end point mark (for example, a member having a different reflectance from the adhesive tape 3 as the silver paper) of the display terminal portion, and can be detected by the first sensor 52. . At this time, the old belt member 11 that has not reached the terminal is preferably driven to rotate by the conveying roller 45, and is sent until the end mark appears, and then cut again.

Further, in the above case, the upper surface of the adhesive tape 3 of the new belt member 11 is pressed by the receiving member 66, and the adhesive tape 3 may be attached to the surface of the receiving member 66, so that it is preferable to accept The surface of the member 66 is subjected to an adhesion prevention treatment or a release release belt or the like.

In addition, there is also a case where the beginning end portion and the end portion are not provided with the adhesive tape 3, and the tape member 11 exposing the release tape 4 is mixed with the tape member 11 having the adhesive tape 3 at the end portion to the end portion, but any When the reel is replaced, the old belt member 11 can be sent out until the end portion is detected, and is often cut off in the vicinity of the end portion.
