Description

  The present invention relates to a tape feeder including a tape feeder that transports a tape that accommodates an electronic component, and an empty tape guide that guides an empty tape after the electronic component is taken out to a collection space, and an arrangement structure of the empty tape guide and The present invention relates to an electronic component mounting apparatus and a carriage provided with the same.

  Conventionally, electronic component mounting apparatuses for mounting electronic components such as chip components and ICs on printed boards have been used. Such an electronic component mounting apparatus includes a tape feeder that transports an electronic component with a tape to a component extraction position of a head portion that adsorbs the electronic component, a collection box that collects an empty tape after the electronic component is removed, and the like. There is a collection space. There is also an electronic component mounting apparatus provided with an empty tape guide for guiding an empty tape sent from a tape feeder to a collection space (for example, see Patent Document 1).

  In this electronic component mounting apparatus, a tape shooter (empty tape guide) for discharging an empty tape delivered from a tape feeder is disposed obliquely downward from the front portion of the tape feeder and extends above the collection box. It is composed of a thin duct. The tape chute is divided into a vertical plane as the front surface of the tape feeder, a steep portion of the upper side that is bent from the vertical plane, and the gentle slope portion of the lower side bent from the lower end of the steep portion The contact surface with the empty tape in the gently inclined portion is provided with a plurality of concave portions and convex portions that are continuous in the discharging direction.

  As a result, the empty tape that advances in the straight direction at the lower end of the tape shooter advances in the recess, and the strong empty tape advances while sliding with the upper surface of the protrusion curved.

Japanese Patent No. 3669158

  However, in the electronic component mounting apparatus described above, since the vertical surface of the tape shooter, which is the front surface of the tape feeder, has no recesses or protrusions that prevent lateral displacement of the empty tape, the empty tape extends from the tip of the tape feeder to the vertical surface. It arrives and is bent downward by the vertical surface. At this time, the empty tape may be bent obliquely downward, and the adjacent empty tapes may be entangled. If the empty tape sent from the tape feeder gets entangled at the first bend, the tape cannot be fed smoothly, hindering the transportation of electronic parts to the parts pick-up position, and the head part being sucked There was a case where a problem that the component could not be properly picked up by the nozzle occurred.

  The present invention has been made to cope with such a problem, and the object thereof is to bend downward by an empty tape guide without being entangled with each other and fed further downward. An arrangement structure of a tape feeder and an empty tape guide, an electronic component mounting apparatus including the same, and a carriage are provided.

  In order to achieve the above-mentioned object, the structural feature of the arrangement structure of the tape feeder and the empty tape guide according to the present invention is that a plurality of tapes each holding a plurality of electronic parts held in a plurality of accommodating portions are conveyed in parallel. And a plurality of empty tapes after the electronic parts have been taken out at the take-out position by a plurality of tape feeders into a collection space disposed below from the empty tape support surfaces provided on the plurality of tape feeders, respectively. A tape feeder having an empty tape guide for guiding and an arrangement structure of empty tape guides, wherein the empty tape guides are arranged in front of a plurality of tape feeders and fed from a plurality of empty tape support surfaces. In the vicinity of the guide surface that guides the recovery space and a portion of the guide surface that is positioned in the forward direction of the plurality of empty tape support surfaces, a plurality of Lies in that it comprises a plurality of protrusions extending vertically arranged side by side at a distance so as to be positioned at avoiding the portion located in the forward direction of extension of the tape bearing surface.

  In the arrangement structure of the tape feeder and the empty tape guide according to the present invention, the empty tape guide is arranged in front of the plurality of tape feeders arranged in parallel. Then, the empty tape guide includes a guide surface for guiding the collection space arranged an empty tape downwardly fed from the tape feeder, the guide surface, a plurality of convex extending vertically arranged side by side at a distance Department. The plurality of convex portions are arranged in the vicinity of the portion of the guide surface in the forward direction where each empty tape support surface extends so as to be positioned away from the portion located in the forward direction where each empty tape support surface extends. Has been.

  In this case, the portion positioned in the forward direction in which the empty tape support surface extends means that if the empty tape support surface is extended straight in the direction of feeding the empty tape with the same width and angle, the extended portion becomes the guide surface. This is the intersection. That is, the plurality of convex portions according to the present invention are arranged such that the interval between the adjacent convex portions is wider than the width of the empty tape support surface. For this reason, the empty tape delivered from the tape feeder hits the guide surface after entering between the adjacent convex portions on the leading end side of the empty tape support surface of the tape feeder. The empty tape to be fed is bent downward by the guide surface in a state in which the lateral deviation is prevented by the pair of convex portions. As a result, there is no entanglement between the empty tapes at the part where the empty tape sent from the tape feeder first bends, so that the tape can be fed smoothly and the electronic parts can be correctly transported to the parts extraction position. Thus, the component suction by the suction nozzle of the head portion can be correctly performed.

  Even when the adjacent empty tapes are different, such as a paper tape and an embossed tape, both of the empty tapes can be prevented from being entangled. Moreover, the convex part extended in an up-down direction may be what extended continuously, or may have arranged several small convex parts intermittently. Furthermore, the distance from the tip of the empty tape support surface of the tape feeder to the guide surface is preferably set as appropriate depending on the rigidity of the empty tape. For example, when the width of the empty tape is 8 mm, 30 to Although it is preferable to set to about 40 mm, depending on the rigidity of the empty tape, it may be less or more.

  Further, another structural feature of the arrangement structure of the tape feeder and the empty tape guide according to the present invention is that the convex portion extends from the upper position to the lower position than the portion of the guide surface located in the front direction where the empty tape support surface extends. It is in providing. According to this, since the empty tape sent out from the tape feeder reaches the guide surface, it is surely positioned between the adjacent convex portions, so the tape feeder is a tape feeder using a hard paper tape and a soft embossed tape. In any of the used tape feeders, the empty tape fed out is regulated so as to be positioned at an appropriate position without lateral displacement, bent downward, and further guided downward.

  Further, another structural feature of the arrangement structure of the tape feeder and the empty tape guide according to the present invention is that the arrangement pitch of the plurality of tape feeders arranged in parallel and the arrangement pitch of the plurality of convex portions are matched. It is in. According to this, since it becomes possible to match the center between each pair of adjacent protrusions of the plurality of protrusions and the center in the width direction of the empty tape support surface, from each of the plurality of tape feeders The center in the width direction of the fed empty tape can be easily adjusted to these. For this reason, the empty tape to be fed can be bent downward while being held at an appropriate position, and further guided downward.

  Further, another structural feature of the arrangement structure of the tape feeder and the empty tape guide according to the present invention is that the guide surface is positioned in front of a plurality of tape feeders and extends vertically, and the upper guide surface includes The lower guide surface is inclined from the lower end toward the plurality of tape feeders and extends downward, and a plurality of convex portions are provided on at least the upper guide surface of the upper guide surface and the lower guide surface. According to this, the empty tape is bent downward and guided downward while being held at an appropriate position in the width direction by the pair of adjacent convex portions and the upper guide surface immediately after being fed out from the tape feeder. The guide surface simply leads the empty tape downward. For this reason, a some convex part can be provided only in a required minimum part.

  Further, another structural feature of the arrangement structure of the tape feeder and the empty tape guide according to the present invention is that the distance between the opposed surfaces of each pair of adjacent convex portions of the plurality of convex portions is different from the guide surface. This is because it gets larger as it goes to the tape feeder side. According to this, the empty tape proceeds to the guide surface side while gradually moving the position from the wide front end side between the pair of convex portions to the center side between the convex portions. For this reason, even if the empty tape reaches between the convex portions while being laterally displaced from the guide surface, the lateral displacement can be corrected by the pair of convex portions. In this case, the surface shape of the cross section of the guide surface and the pair of convex portions may be U-shaped. According to this, even when the width of the blank tape fed from the tape feeder is small, the blank tape to be fed can be bent downward and guided downward while being positioned at the center between the pair of convex portions.

  In addition, a structural feature of the electronic component mounting apparatus according to the present invention is that the arrangement structure of the tape feeder and the empty tape guide described above is attached. According to this, an electronic component mounting apparatus having an arrangement structure of a tape feeder and an empty tape guide that can be bent downward and guided downward toward a collection space without entanglement of empty tapes fed from the tape feeder. Can be obtained.

  Further, another structural feature of the electronic component mounting apparatus according to the present invention includes a mounting apparatus body and a carriage that can be attached to and detached from the mounting apparatus body, and the arrangement of the tape feeder and the empty tape guide described above. The empty tape guide in the structure is provided in the mounting apparatus main body, and the tape feeder is provided in the carriage. According to this, the arrangement structure of the tape feeder and the empty tape guide described above is configured by attaching the carriage to the mounting apparatus main body. In this way, by using the carriage, work efficiency is improved because a tape feeder, a tape, and the like can be installed in advance on the carriage that is not in use.

  In addition, the structural feature of the carriage according to the present invention is that the arrangement structure of the tape feeder and the empty tape guide described above is attached and is detachable from the main body of the electronic component mounting apparatus. According to this, it is possible to obtain a carriage having a tape feeder and an empty tape guide arrangement structure that can be bent without being entangled with each other and guided to a lower collection space.

  Moreover, the front-end | tip blade part of the fixed blade 38a is formed in the linear form orthogonal to the moving direction of the movable blade 38b, and the front-end | tip blade part of the movable blade 38b is formed in the V shape where the center was depressed in planar view. . For this reason, in a state where the movable blade 38b is separated from the fixed blade 38a, the empty carrier tape 18a is sent from the empty tape guide 30 to the communication hole 37a for dropping, and the movable blade 38b is moved forward in that state. The empty carrier tape 18a can be cut. In this case, the empty carrier tape 18a is cut to a length of about 100 mm. A shock absorber 39 for buffering an impact generated by stopping the movement of the movement support portion 38c is installed below the movement support portion 38c.

  Note that the position of the mounting hole 36d on the upper side of the guide portion 36 is, for example, in a bent portion when a flat head screw, a pan head screw, a round head screw, a hexagon head bolt, or the like with a protruding head is used as a fixture. In the case of being arranged, since the head obstructs the first downward bending of the empty carrier tape 18a, the front end side of the empty tape support surface 23c with respect to the tape feeder 20 attached to the feeder installation portion 16 The downward inclined surface is extended forward at the same inclination angle so that the position of the upper fixture is higher than the height of the portion intersecting the guide surface portion 36a. The position of the lower fixture (the position of the lower mounting hole 36d) is set to be lower than the upper end of the upper auxiliary surface 32a, and the tip of the empty carrier tape 18a reaches the head of the fixture. Even if it is bent forward, it is guided further downward on the inner surface of the upper auxiliary surface 32a.

  When the electronic component B is mounted on the printed circuit board A using the electronic component mounting apparatus 10 configured as described above, a plurality of tape feeders 20 are attached to the feeder installation unit 16 and the state shown in FIG. To. In FIG. 1, only one tape feeder 20 is attached to each feeder installation unit 16, but a number of tape feeders 20 that can be installed are attached to each feeder installation unit 16. Each tape feeder 20 is loaded with a tape 18 before being attached to each feeder installation section 16, and preparations for installation on each feeder installation section 16 are made.

  That is, the tape 18 is extended from the reel 45a through the conveyance path 23a of the housing case 21 to the conveyance path 23b side of the main body case 22, and the tip thereof reaches the downstream side of the conveyance path 23b. . A dummy tape equivalent to the cover tape 18b is adhered to the cover tape 18b at the front end of the tape 18, and the cover tape 18b is slightly peeled off from the front end of the tape 18 so as to be inserted into the insertion hole 24b of the tape guide 24a. The tip of the dummy tape that is bent rearward and connected to the cover tape 18b by adhesion is sandwiched between the drive side roller 26c and the pinch roller 26d.

  Further, at the leading end of the tape 18 that has reached the downstream side of the transport path 23b, several claws on the upper end side of the sprocket 25d are inserted into the engagement hole 18d of the carrier tape 18a that is exposed by slightly peeling the cover tape 18b. Engage the parts. The pre-installation preparation of the tape feeder 20 to the feeder installation unit 16 is thus completed. With the tape feeder 20 installed in the feeder installation unit 16, the electronic component mounting apparatus 10 starts mounting production of the printed circuit board A. When the control board stored in the storage box 28 operates the sending motor 25a and the take-up motor 26a in synchronization, the carrier tape 18a is fed forward from the claw and forward from the claw. And the cover tape 18b is pulled rearwardly on the upper side of the insertion hole 24b and forwardly on the lower side of the insertion hole 24b via the dummy tape, so that the tape 18 is sequentially fed out from the reel 45a.

  The cover tape 18b is sequentially peeled from the carrier tape 18a at the insertion hole 24b portion of the tape guide 24a. The carrier tape 18a is sent toward the take-out position a on the transport path 23b, and the cover tape 18b is sent toward the inside of the cover tape collecting part 21a by the take-out part 26. When the receiving portion 18c of the carrier tape 18a reaches the take-out position a, the carrier tape 18a stops once, and the electronic component B from which the suction nozzle of the head unit 13 is exposed by the control unit of the electronic component mounting apparatus 10 is displayed. Is picked up by adsorption. The picked-up electronic component B is mounted on the printed circuit board A.

  Carrier tape 18a the electronic component B has become empty taken out by the suction nozzle, by the operation in synchronization with the delivery motor 25a and the take-up motor 26a, it is conveyed toward the upper empty tape bearing surface 23c forwardly. Each time the electronic component B is taken out, the carrier tape 18a is conveyed forward, proceeds from the front horizontal surface of the empty tape support surface 23c to the downward inclined surface on the leading end side, and passes through the air from the leading end of the downward inclined surface to the empty tape. Proceeding obliquely downward toward the guide portion 36 of the guide 30. The carrier tape 18a has a downward bending amount that varies depending on the bending rigidity. When the bending rigidity is large, the downward bending amount is smaller than when the bending is small.

  When the leading end of the carrier tape 18a passes through the window portion of the empty tape guide 30 and reaches the guide portion 36 by conveyance by the motors 25a and 26a, the center in the width direction of the carrier tape 18a is in the width direction of the guide portion 36. When slightly shifted from the center, the carrier tape 18a hits one of the convex portions 36BC on both sides of the opposing guide surface portion 36a. The leading end portion of the carrier tape 18a that hits one convex portion 36BC is moved downward along the contacted portion of the convex portion 36BC by conveyance, and the position in the width direction is shifted to the center side in the width direction of the guide portion 36. To reach the guide surface 36a.

  Thereafter, the carrier tape 18a is a pair of protrusions 36BC, are straight bent downward by the guide surface part 36a by the transport while being prevented from lateral displacement, will be sent down further along the guide surface 36a. When the leading end portion of the carrier tape 18a reaches the lower guide surface portion 31b, the carrier tape 18a is urged rearward due to the inclination of the lower guide surface portion 31b, but the lower auxiliary surface portion 32b is positioned rearward. For this reason, the carrier tape 18a is sent downward by conveyance while the position in the front-rear direction is regulated by the lower guide surface portion 31b and the lower auxiliary surface portion 32b. If the tip of the carrier tape 18a is cut obliquely rather than perpendicularly to the direction of the tape, the carrier tape 18a is easily displaced laterally when it is bent downward by the guide surface portion 36a. However, the pair of convex portions 36BC Is prevented from being laterally shifted.

  When the carrier tape 18a passes through the upper part of the empty tape guide 30, the carrier tape 18a is prevented from being laterally displaced by the convex portion 36BC, and is regulated to be in a substantially vertical posture by the guide surface portion 36a. When passing through the upper side part, even if there is no convex part 36BC, it is in a state where it hardly deviates in the width direction. In this state, the carrier tape 18a is fed downward on the lower side of the empty tape guide 30. When the carrier tape 18a having a predetermined length passes through the portion where the cutter 38 is installed, the moving blade 38b moves and the carrier tape 18a is cut and falls into the collection box.

  Such an operation is sequentially performed by the plurality of tape feeders 20 and the cutters 38 attached to the feeder installation unit 16, and the plurality of tapes 18 are processed. At this time, the plurality of carrier tapes 18a simultaneously pass through the empty tape guide 30, but as described above, each carrier tape 18a is guided by each guide portion 36 and fed downward. Therefore, the plurality of carrier tapes 18a proceed to the cutter 38 without being entangled with each other adjacent to each other, cut into a predetermined length, and accommodated in a collection box.

  Thus, in the electronic component mounting apparatus 10 according to the present embodiment, the empty tape guide 30 is disposed in front of the tape feeder 20, and the empty tape guide 30 is further bent by bending the carrier tape 18a downward. It includes a guide surface portion 36a that leads downward, and a plurality of convex portions 36BC that regulate the position of the carrier tape 18a in the width direction to be an appropriate position. For this reason, the empty carrier tape 18a fed out from the tape feeder 20 eliminates the shift in the width direction after entering between the pair of convex portions 36BC on the leading end side of the empty tape support surface 23c of the tape feeder 20, and guide surface portion 36a. It hits.

  The carrier tape 18a is bent downward by the guide surface portion 36a while being prevented from being laterally shifted by the convex portion forming pieces 36b and 36c, and further guided downward and guided to the collection box. As a result, each carrier tape 18a does not get entangled with the other carrier tape 18a at the top of the empty tape guide 30, and the tape 18 can be smoothly fed, so that the electronic components can be sequentially conveyed to the component take-out position a. There is no hindrance, and the component suction by the suction nozzle of the head portion can be correctly performed.

  That is, even if the operator does not hold the carrier tape 18a and bend it straight downward, each time the electronic component B is taken out, the sending motor 25a and the take-up motor 26a operate in synchronism, and the empty tape The carrier tape 18a is conveyed forward on the support surface 23c, bent downward by the guide surface portion 36a in a state in which lateral deviation is prevented by the convex portion forming pieces 36b and 36c, and further guided downward to be led to the collection box. be able to. The heights of the upper end portions of the guide surface portion 36a and the convex portion 36BC are the same as the height of the portion intersecting with the empty tape guide 30 by extending the downward inclined surface on the front end side of the empty tape support surface 23c at the same inclination angle. The intermediate tape height is the height of the front horizontal surface of the empty tape support surface 23c. For this reason, the carrier tape 18a sent out from the tape feeder 20 reaches the guide surface portion 36a after reliably entering between the pair of convex portions 36BC.

  Furthermore, since the arrangement pitch of the convex portions 36BC provided in the empty tape guide 30 is matched to the arrangement pitch of the plurality of tape feeders 20 attached to the feeder installation portion 16, the distance between each pair of convex portions 36BC is set. The center and the center in the width direction of the carrier tape 18a fed from the plurality of tape feeders 20 can be matched. Therefore, the carrier tape 18a can be bent straight downward while being held in an appropriate position, and further guided downward.

  Further, since the convex portion 36BC is provided in the minimum necessary portion only on the upper side of the empty tape guide 30, the structure of the empty tape guide 30 is simplified and the cost can be reduced. Furthermore, since the distance between the opposing surfaces of the pair of convex portions 36BC increases from the guide surface portion 36a side to the tape feeder 20 side, the carrier tape 18a gradually increases from the wide end side between the pair of convex portions 36BC. Then, the position moves toward the guide surface 36a side while moving the position toward the center between the pair of convex portions 36BC.

Each empty tape guide 30 in FIG. 7 is not installed and fixed on the mounting apparatus main body 50a, but is installed and fixed on each carriage 52, respectively. In FIG. 7, 51 indicates a base. The rest of the configuration of the electronic component mounting apparatus 50 is the same as that of the electronic component mounting apparatus 10 described above. Accordingly, the same parts are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 10 shows a carriage 52 provided with a tape feeder and empty tape guide arrangement structure according to a third embodiment of the present invention. The carriage 52 is used by being attached to the main body 50a of the electronic component mounting apparatus 50, and the mounting apparatus main body 50a is used from the mounting apparatus main body 40a shown in FIGS. 8 and 9 to the empty tape guide 30, the cutter 38 and its It has a configuration with the peripheral part removed. The carriage 52 has a configuration in which the empty tape guide 30, the cutter 38, and the peripheral portion thereof are provided on the carriage 42 of the second embodiment described above. The portion where the empty tape guide 30 and the cutter 38 are provided is connected to the carriage 52 by a pair of left and right side walls 51 (only one is shown), and the upper side portion of the pair of side walls 51 is a cut carrier. It is composed of a duct for dropping the tape 18a into the collection box 44.

  About the structure of the other part of this trolley | bogie 52, it is the same as each corresponding part of the trolley | bogie 42 with which the electronic component mounting apparatus 40 mentioned above is equipped. Therefore, the same reference numerals are given to the same parts. According to this, it is possible to obtain a carriage 52 having an arrangement structure of a tape feeder and an empty tape guide that does not entangle the empty carrier tapes 18a delivered from the tape feeder 20. The operational effects of the electronic component mounting apparatus 50 including the carriage 52 and the mounting apparatus main body 50a are the same as those of the electronic component mounting apparatus 40 described above.

  Further, the arrangement structure of the tape feeder and the empty tape guide, the electronic component mounting apparatus, and the carriage according to the present invention are not limited to the above-described embodiments, and can be implemented with appropriate modifications. For example, in each of the above-described embodiments, the convex portion 36BC extends continuously up and down, but the convex portion 36BC may be configured by a plurality of convex portions that are intermittently arranged up and down. Moreover, the distance from the front-end | tip part of the empty tape support surface 23c of the tape feeder 20 to the guide surface part 36a can be suitably set with the magnitude | size of the rigidity of the carrier tape 18a.

  Further, in each of the above-described embodiments, the distance between the opposing surfaces of the convex forming pieces 36b and 36c is increased from the guide surface portion 36a toward the tape feeder 20 side. You may make it the surface shape of the cross section with the part formation pieces 36b and 36c become U shape. According to this, even when the width of the carrier tape 18a is small, the carrier tape 18a can be bent downward while being positioned at the center between the pair of convex portions 36BC, and further guided downward. Moreover, you may extend convex part 36BC to the lower end part of the lower guide surface part 31b. Further, in the above-described embodiment, the guide portion 36 including the guide surface portion 36a and the convex portion forming pieces 36b and 36c is used, but the guide portion 36 is not used, and the convex portion is provided directly on the guide portion mounting portion 31a. Also good. In this case, the surface of the guide portion attachment portion 31a becomes the guide surface according to the present invention.

  The carrier tape 18a has a very high bending rigidity, and the carrier tape 18a is slightly increased by its own weight even when the carrier tape 18a is released from the descending inclined surface as it advances from the front horizontal surface of the empty tape support surface 23c to the descending inclined surface. Since it hangs down, the heights of the upper end portions of the guide surface portion 36a and the convex portion 36BC are substantially equal to or higher than the height of the front horizontal surface of the empty tape support surface 23c of the tape feeder 20 attached to the feeder installation portion 16. By doing so, the carrier tape 18a delivered from the tape feeder 20 reaches the guide surface portion 36a after reliably entering between the pair of convex portions 36BC.

  Still further, the base surface portion 31 may be formed from a resin filled with glass fibers. In this case, it is assumed that the guide surface portion 36 a and the convex portion forming pieces 36 b and 36 c are all integrally formed as a part of the base surface portion 31. When the convex portion that prevents the adjacent carrier tape 18a from being entangled is formed over the entire length of the guide surface portion from the upper guide surface portion 31a to the lower guide surface portion 31b, the carrier tape 18a is bent downward. In addition to preventing the adjacent carrier tape 18a from being entangled, the carrier tape 18a is prevented from being entangled in the vicinity of the lower end opening of the empty tape guide 30, so that the carrier tape 18a can be smoothly transferred to the collection box without the cutter 38. Can be guided.

  In addition, the upper side portion of the empty tape guide 30 and the guide surface portions 36a of the plurality of guide portions 36 attached to the upper side portion are substantially vertical. The carrier tape 18a having high bending rigidity can be reliably bent downward. For the carrier tape 18a having low bending rigidity, the upper side portion of the empty tape guide 30 and the guide surface portions 36a of the plurality of guide portions 36 attached to the upper side portion are angled backward from the vertical. As a result, an empty space in front of the empty tape guide 30 can be enlarged, and this space can be effectively used.

  Furthermore, as a fixture to the guide portion attachment portion 31a of the guide portion 36, for example, if a flat head screw is used and the head does not protrude from the surface of the guide surface portion 36a, the positions of the upper and lower fixtures, that is, The position of the mounting hole 36b is not particularly restricted. Similarly, when spot welding is employed as a method of fixing the guide portion 36 to the guide portion attachment portion 31a, the welding location is not particularly restricted.

  In each of the above embodiments, the tape feeder 20 is of a type that feeds the tape by an electric motor. However, the tape feeder 20 abuts when the pressing rod that moves up and down in conjunction with the lifting and lowering of the suction nozzle of the head unit is lowered, and the tape feeding mechanism. And a type in which a rod receiving member connected to the tape feeding mechanism is mounted. In this case, the tape is fed every time the pressing rod is lowered. Alternatively, a tape feed mechanism and an air cylinder that drives the tape feed mechanism are mounted, and the tape feed is performed by receiving the supply of pressure air controlled by the air valve mechanism on the mounting machine body side. good.
