The Y table 8 is driven along the Y direction by a Y drive source 9 provided on the X table 6. The panel 1 is supplied to the upper surface of the Y table 8 with the peripheral portion protruding from the peripheral portion of the Y table, and is held immovable by means such as vacuum suction. Thereby, the panel 1 can be positioned in the XY directions by the panel table 2.

  The index table 4 is provided with a rotating shaft 11 at the center, and the rotating shaft 11 is intermittently rotated clockwise by a predetermined angle by a θ drive source 12. In this embodiment, the index table 4 is rotationally driven at an angle of 60 degrees per time.

  On the upper surface of the index table 4, six supports 13 are provided at intervals of 60 degrees as shown in FIG. In FIG. 1, only two supports 13 are shown, and the other supports 13 are omitted. The support 13 has an L-shaped side surface, and a movable body 14 is supported on the vertical surface by a linear guide 15 so as to be movable in the vertical direction (up and down direction).

  A spring (not shown) is provided between the movable body 14 and the support body 13 to elastically hold the movable body 14 at a predetermined height. A suction head 16 having an L-shaped side surface as a mounting means is provided on the lower end surface of each movable body 14. The suction head 16 sucks and holds the TCP 3 supplied from a component supply unit 21 as a component supply device, which will be described later, at a position indicated by A in FIGS. 1 and 2, and is mounted on the panel 1.

  The index table 4 has five positions indicated by B to F in FIG. 2, that is, a total of six positions in addition to the position indicated by A, that is, the supply position A. The five positions B to F will be described later.

  The component supply unit 21 divides the TCP 3 from the carrier tape 22 as shown in FIG. That is, the component supply unit 21 includes a pair of left and right end cutting means 24 for cutting a portion in which engagement holes 22a that engage with a feed sprocket (not shown) at both ends in the width direction of the carrier tape 22 are formed, Separating and cutting means 25 for cutting a portion set in a predetermined width dimension by cutting the both ends in the width direction by the end cutting means 24 and a conveying means for conveying the carrier tape 22 at a predetermined pitch. 26.

  The pair of left and right end cutting means 24 has a pair of linear guides 28 disposed along a direction perpendicular to the conveying direction indicated by arrow S in FIG. A first cutter table 29 is movably supported by the linear guide 28. A screw shaft 31 is screwed onto the first cutter table 29, and the screw shaft 31 is rotationally driven by a first servomotor 32. Thereby, the first cutter table 29 is driven along the width direction of the carrier tape 22 along the linear guide 28 and can be positioned at a predetermined position.

  A first support member 33 is erected on the first cutter table 29. A pair of second servomotors 34 are provided on one side surface of the first support member 33 at a predetermined interval in the vertical direction with the axis line horizontal. The rotation shaft of each servo motor 34 protrudes to the other side of the first support member 33, that is, the carrier tape 22 side. Roller-like upper and lower cutters 35a and 35b constituting a cutting mechanism are fitted into the protruding ends of the respective rotary shafts. The upper cutter 35a and the lower cutter 35b are in contact with each other, with the outer peripheral surface formed in a sharp mountain shape.

  As a result, when the end portion in the width direction of the carrier tape 22 passes between the upper cutter 35a and the lower cutter 35b that are rotationally driven, the end portions are cut by the pair of cutters 35a and 35b. Yes. FIG. 3 shows the cut end portion 22b.

  The first cutter table 29 provided with a pair of cutters 35a and 35b can be positioned and adjusted in the width direction of the carrier tape 22 by the first servo motor 32. As a result, the width dimension of both end portions 22b in the width direction of the carrier tape 22 cut by the pair of end cutting means 24 can be changed. That is, the width dimension of the carrier tape 22 whose end 22b is cut by the pair of end cutting means 24 can be arbitrarily set.

  The separation / cutting means 25 is arranged downstream of the end cutting means 24 in the transport direction of the carrier tape 22, and is arranged along the width direction of the carrier tape 22 like the end cutting means 24. And a pair of linear guides 37 (shown in FIG. 4). The linear guide 37 is provided with a second cutter table 38 so as to be movable. A screw shaft 39 is screwed onto the second cutter table 38. The screw shaft 39 is rotationally driven by a third servo motor 41. Thereby, the second cutter table 38 is driven along the width direction of the carrier tape 22.

  The second cutter table 38 is provided with a second support member 42 having an upper side 42a and a lower side 42b and having a U-shaped side surface. The upper side 42a and the lower side 42b of the support member 42 are set longer than the width dimension of the carrier tape 22, and a fourth servo motor 43 is provided on one side surface of the tip.

  The rotation shaft of each servo motor 43 protrudes from the other side surfaces of the upper side 42a and the lower side 42b, and roller-like upper cutters 44a and lower cutters 44b are fitted to the protruding ends. The upper cutter 44a and the lower cutter 44b are in contact with sharply formed outer peripheral surfaces.

  Accordingly, when the upper cutter 44a and the lower cutter 44b are driven to rotate and the second cutter table 38 is driven along the width direction of the carrier tape 22, the pair of end cutting means 24 of the carrier tape 22 is provided. Thus, the portion where both end portions in the width direction are cut is cut in the width direction along a cutting line C shown by a chain line in FIG. That is, the carrier tape 22 having both ends in the width direction cut by a predetermined length, the TCP 3 as an electronic component is divided.

  The carrier tape 22 is intermittently conveyed by the conveying means 26 at a predetermined pitch in the arrow S direction, that is, at a pitch corresponding to the length of the TCP 3. The transport means 26 has a drive cylinder 46 disposed on the leading end side in the transport direction of the carrier tape 22 with the axis of the drive shaft 46 a being the same as the transport direction S of the carrier tape 22. A chuck 47 is provided at the tip of the drive shaft 46 a of the drive cylinder 46 so as to be opened and closed and pinch the tip of the carrier tape 22.

  Accordingly, when the chuck 47 is driven in the backward direction indicated by the arrow B in FIG. 3 with the tip end portion of the carrier tape 22 being sandwiched, the carrier tape 22 is conveyed at a predetermined pitch in the arrow S direction. become.

  The stroke of the drive shaft 46a of the drive cylinder 46 can be set. As a result, the transport pitch of the carrier tape 22 transported with the tip held between the chucks 47 can be set to a predetermined length.

  The leading end portion of the carrier tape 22 conveyed at a predetermined pitch by the conveying means 26, that is, the portion divided by the separating / cutting means 25 as TCP3 is separated before being separated by the separating / cutting means 25 as shown in FIG. Is held by suction on the holding table 51. As a result, the TCP 3 separated from the carrier tape 22 by the separation / cutting means 25 is sucked and held on the holding table 51.

  As shown in FIG. 4, on the upper surface of the holding table 51, there is a clearance groove 51a for preventing the chuck 47 of the transport means 26 from interfering with the holding table 51 when going to grip the leading end of the carrier tape 22. Is formed over the entire length of the chuck 47 in the moving direction.

  When the TCP 3 is separated from the carrier tape 22, the tip of the carrier tape 22 is held by a roller (not shown) that prevents the carrier tape from bending downward.

  The TCP 3 sucked and held on the holding table 51 is sucked and taken out from the holding table 51 by a take-out nozzle 52 as take-out means. The take-out nozzle 52 is driven in the X, Y, and Z directions by a drive mechanism (not shown), and transports the TCP 3 taken out from the holding table 51 onto the delivery table 53 shown in FIG. . The delivery table 53 is driven in the X direction by a drive mechanism (not shown).

  The delivery table 53 that has received the TCP 3 is driven in the X direction and positioned below the supply position A of the index table 4. Next, the delivery table 53 is driven in the upward direction. Thereby, the TCP 3 placed on the delivery table 53 is sucked and held by the suction head 16 provided at the lower end of the movable body 14.

  When the suction head 16 sucks the TCP 3 at the position A, the index table 4 is rotated 60 degrees, and the suction head 16 is sequentially positioned at positions B to F shown in FIG. At position B, a terminal (not shown) formed on TCP 3 is brushed. At the position C, one end of the TCP 3 sucked by the suction head 16 is pressed by a gauge (not shown), and the one end of the TCP 3 is positioned so as to coincide with the side surface of the suction head 16.

  The TCP 3 positioned at the position C is imaged by the first imaging camera 55. An imaging signal from the first imaging camera 55 is processed by an image processing unit (not shown), and the center coordinates of an alignment mark (not shown) of the TCP 3 in a state of being positioned at the position C are calculated.

  While the TCP 3 is being imaged by the first imaging camera 55 at the position C, the panel table 2 is positioned at a predetermined position, and the panel 1 provided on the panel table 2 at that position is provided on the panel 1 shown in the figure. The second alignment mark that is not to be captured is picked up by the second camera 56.

  While the TCP 3 is imaged at the position C and moved to the position D, the panel table 2 is driven in synchronization with the operation while the positions in the X and Y directions are controlled. The panel 1 held on the panel table 2 moves to the position D so that the center of the position where the TCP 3 is mounted coincides with the center of the first alignment mark of the TCP 3 positioned at the position D.

  When the panel 1 moves, the pressing cylinder 58 provided above the position D is operated as shown in FIG. 1, and the movable body 14 is driven in the downward direction by the rod 58a. Accordingly, the TCP 3 held by the suction head 16 at the lower end of the movable body 14 is mounted on the panel 1. At this time, the lower surface of the portion of the panel 1 where the TCP 3 is mounted is held by the backup tool 59.

  When the TCP 3 is mounted on the panel 1, the suction head 16 rises together with the rod 58 a of the pressing cylinder 58, and then the index table 4 is driven to rotate 60 degrees, and the suction head 16 is positioned at the position E. Position E is a discharge position, and TCP3 supplied to and held by the suction head 16 at position A is a defective product. When the first imaging camera 55 cannot reliably recognize the first alignment mark of TCP3 at the position C, The TCP 3 is not mounted on the panel 1 at the position D, but is discharged at the position E.

  Further, the index table 4 is rotated 60 degrees, and the suction head 16 is positioned at the sixth position F. At this position F, the lower end surface of the suction head 16 is imaged by the third imaging camera 61. A mark (not shown) having a predetermined shape such as a circle is provided on the lower end surface of the suction head 16.

  Accordingly, the X and Y coordinates of the center of the mark when the index table 4 is accurately rotated by 60 degrees are set in advance, and the set coordinates and the X and Y of the center of the mark obtained by the third imaging camera 61 are set. Since it can be calculated whether or not there is a deviation in the rotation angle of the index table 4 compared with the coordinates, the rotation angle of the index table 4 is corrected according to the deviation.

  As described above, according to the mounting apparatus having the above-described configuration, the component supply unit 21 that supplies the TCP 3 to the suction head 16 of the index table 4 cuts both ends in the width direction of the carrier tape 22 by the pair of end cutting means 24. After that, the carrier tape 22 having both ends cut by the separating and cutting means 25 is cut into a predetermined length so that the TCP 3 is separated from the carrier tape 22.

  The dividing width of both ends in the width direction of the carrier tape 22 by the end cutting means 24 is arbitrarily determined by positioning the upper cutter 35a and the lower cutter 35b by the first servo motor 32, and the first servo motor. It can be set automatically by operating 32 by a setting signal.

  The cutting length of the carrier tape 22 cut by the separating and cutting means 25 can be arbitrarily set by setting the stroke of the chuck 47 driven by the drive cylinder 46 of the conveying means 26 while holding the tip of the carrier tape 22. Can be set automatically.

  Therefore, when the size or type of the panel 1 is changed and the size of the TCP 3 mounted on the panel 1 is changed, the width dimension of the carrier tape 22 cut by the separating and cutting means 25 according to the size of the TCP 3. Then, the TCP 3 having a different size can be divided from the carrier tape 22, that is, cut out only by changing the length dimension to be cut by the separating and cutting means 25.

  As a result, it is possible to cope with without changing the mold by stopping the line according to the size of the TCP 3 to be changed, as in the conventional case where the TCP 3 is punched from the carrier tape 22 by the mold. Thus, it is possible to significantly improve productivity and reduce the burden on the worker.

  In the above embodiment, the chuck is linearly driven by the driving cylinder as the conveying means for conveying the carrier tape at a predetermined stroke. However, instead of the driving cylinder, other linear driving means such as a linear motor is used. The chuck may be driven linearly, and both ends of the carrier tape in the width direction are clamped by a pair of upper and lower friction rollers without using the chuck, and the rotation of the friction roller is controlled to move the carrier tape to a predetermined stroke. You may make it convey by.

  In addition, although a pair of upper and lower roller cutters are used for the end cutting means and the separation cutting means, the carrier tape may be cut using laser light instead of the roller cutter. The carrier tape may be cut by a cutter that is driven up and down or a cutter that rotates with one end as a fulcrum.

  When the width dimension of the carrier tape is set to the width dimension of the electronic component, only the separation cutting means is used without using the end cutting means for setting the width dimension by cutting both ends in the width direction of the carrier tape. What is necessary is just to cut | disconnect the said carrier tape to predetermined length.
