Description

The present invention relates to a workpiece insertion stabilizing device and a workpiece insertion stabilizing method.

2. Description of the Related Art Taping apparatuses having a taping mechanism for inserting a plurality of works such as electronic components into a carrier tape are known. For example, according to a taping mechanism as described in Patent Document 1, works are individually conveyed and individually inserted into cavities of a carrier tape.

In order to improve the productivity of the carrier tape into which the workpiece has been inserted, the taping described in Patent Document 1 involves blowing off the workpiece using air blowing and vacuum suction and applying it to the slanted guide on the carrier tape. The workpiece is quickly inserted into the cavity.

Patent No. 5282858 Japanese Patent Application Publication No. 1-226618

If a large impact is applied to the workpiece before it is inserted into the cavity of the carrier tape, problems such as damage or failure may occur in the workpiece. When a defective workpiece is inserted into a carrier tape, the carrier tape itself becomes a defective product. That is, if a problem occurs in the workpiece, the productivity of the carrier tape into which the workpiece is inserted by the taping device will be deteriorated. Therefore, in the process of inserting the workpiece into the cavity of the carrier tape, it is required to avoid applying a large impact to the workpiece.

On the other hand, in the taping mechanism described in Patent Document 1, the work is inserted into the cavity of the carrier tape by blowing the work horizontally with air. A workpiece that is blown horizontally by an air blower has difficulty reaching the cavity in a stable trajectory. Therefore, the workpiece may collide with surrounding members between the blown-off position and the cavity position. As a result, an impact may be applied to the workpiece. Furthermore, since the trajectory is not stable, the workpiece may be inserted obliquely into the cavity. When the carrier tape is driven in the taping device, the obliquely inserted workpiece collides with other members of the taping device, which may cause impact to be applied to the workpiece. Alternatively, the work may be damaged due to friction between the work and other members.

Further, in the taping mechanism described in Patent Document 2, it is not possible to confirm whether the workpiece has been properly inserted into the cavity using an imaging device or the like due to its structure. Therefore, the carrier tape may be driven while the workpiece is inserted into the cavity in an inappropriate manner. In such a case, the work may collide with other members of the taping device, and an impact may be applied to the work. Alternatively, the work may be damaged due to friction between the work and other members.

In this way, if the workpiece does not reach the cavity stably, an impact may be applied to the workpiece, and as a result, a defect may occur in the workpiece. The present invention has been made in consideration of these points, and it is an object of the present invention to stabilize the behavior of the work when inserting the work into the carrier tape, thereby stably inserting the work into the cavity of the carrier tape. purpose.

FIG. 3 shows a top view of the carrier tape 10. As shown in FIG. 3, the carrier tape 10 is provided with a plurality of cavities 10a into which workpieces 100 are inserted. The cavities 10a are arranged in one direction d1, preferably regularly arranged in one direction d1. The dimensions of the cavity 10a are appropriately set depending on the work 100 to be inserted, but for example, the length in one direction d1 is 0.37 mm or more and 1.5 mm or less, and the length in the direction perpendicular to one direction d1 is 0.37 mm or more and 1.5 mm or less. It is a rectangular concave portion with a size of 67 mm or more and 2.22 mm or less. Further, the depth of the cavity 10a is, for example, 0.37 mm or more and 1.54 mm or less. The interval between cavities 10a adjacent to each other in one direction d1 is, for example, 2 mm or more and 4 mm or less.

Further, as shown in FIG. 3, the carrier tape 10 is provided with a plurality of feed holes 10b that engage with feed teeth of a pulley 55, which will be described later. The size of the feed hole 10b is, for example, a circular through hole with a diameter of 1.5 mm or more and 1.6 mm or less. The feed holes 10b are arranged side by side in one direction d1, preferably regularly lined up in one direction d1. The spacing between the feed holes 10b in one direction is, for example, 2 mm or more and 6 mm or less. The feed hole 10b is provided at a position corresponding to the arrangement of the cavity 10a so as to be used for positioning the cavity 10a. In the example shown in FIG. 3, one feed hole 10b is provided corresponding to two cavities 10a.

The carrier tape 10 before the workpiece 100 is inserted is held wound around the supply reel 11, and the carrier tape 10 after the workpiece is inserted is pasted with a top tape that seals the cavity 10a. After that, it is wound onto a take-up reel 12 and collected. The carrier tape 10 is driven in one direction d1.

The supply reel 11 holds the carrier tape 10 with no workpiece 100 inserted therein, and supplies the carrier tape 10 to the workpiece insertion stabilizing device 20 . The supply reel 11 has a disk shape and is rotatable around its center. The carrier tape 10 before the workpiece 100 is inserted into the cavity 10a is wound around the supply reel 11 along its outer periphery. The supply reel 11 is arranged on the upstream side in one direction d1 in which the carrier tape 10 is driven.

The take-up reel 12 collects and holds the carrier tape 10 with the workpiece 100 inserted therein. The take-up reel 12 has a disk shape and is rotatable around its center. A carrier tape 10 with a workpiece 100 inserted into a cavity 10a is wound around the take-up reel 12 along its outer periphery. The take-up reel 12 is arranged on the downstream side in one direction d1 in which the carrier tape 10 is driven.

The workpiece insertion stabilizing device 20 inserts the workpiece 100 into the carrier tape 10 supplied from the supply reel 11 . The workpiece insertion stabilizing device 20 is provided with a tape passage 25 through which the carrier tape 10 passes. The tape passage 25 is a space through which the carrier tape 10 can pass. The workpiece insertion stabilizing device 20 inserts the workpiece 100 into the carrier tape 10 passing through the tape path 25 at the taping position P2. That is, by driving the carrier tape 10, the cavities 10a are sequentially arranged at the taping position P2. The width of the tape passage 25 is larger than the width of the carrier tape 10 so that the carrier tape 10 can pass therethrough.

The workpiece insertion stabilizing device 20 includes a base 30, an index table 40 provided on the base 30, and a taping portion 50 provided overlapping a part of the index table 40 and a part of the tape passage 25. and a pump means 70 connected to the taping position P2 via the cavity 10a of the carrier tape 10. Further, the workpiece insertion stabilizing device 20 includes an imaging device 80 that images the taping position P2, a workpiece insertion magnet 60 that inserts the workpiece 100 into the cavity 10a at the taping position P2, and a workpiece inserted into the cavity 10a of the carrier tape 10. 100, and a workpiece holding magnet 65 during transportation. Furthermore, the workpiece insertion stabilizing device 20 includes a parts feeder 21 and a linear feeder 22 that supply the workpieces to the index table 40, and a pulley 55 that is disposed facing the taping section 50 via the tape passage 25. ing.

Each component of the workpiece insertion stabilizing device 20 will be described below.

The parts feeder 21 aligns the plurality of works 100 with the same orientation. In the example shown in FIG. 1, the parts feeder 21 has a substantially cylindrical shape with a circular opening, but it may have any shape with an opening. A plurality of works 100 are supplied to the parts feeder 21 through the opening. The parts feeder 21 includes, for example, a vibration device (not shown) and a groove portion 21a extending along the direction of vibration caused by the vibration device. When the parts feeder 21 has a cylindrical shape, the groove portion 21a extends in a spiral shape. As the vibration device vibrates, the work 100 moves while being fitted into the groove 21a. Thereby, the works 100 supplied to the parts feeder 21 are aligned in the same direction. The aligned works 100 are sent to the linear feeder 22.

The linear feeder 22 receives the aligned workpieces 100 from the parts feeder 21 and conveys the workpieces 100 in a lined-up state. The linear feeder 22 has a groove (not shown) extending in a straight line, and conveys the work along the groove. The groove portion of the linear feeder 22 extends continuously with the groove portion 21a of the parts feeder 21. As shown in FIG. 3, the works 100 that have passed through the linear feeder 22 are individually fed to the index table 40 with their orientations aligned in the same direction.

The base 30 supports an index table 40. The base 30 has an inclined surface 31 that is inclined so that the side of the taping position P2 is on the lower side in the vertical direction. The angle of inclination of the inclined surface 31 is preferably constant. That is, it is preferable that the inclined surface 31 is a flat surface. Further, the inclined surface 31 is inclined with respect to the horizontal direction at an angle of 20° or more and 40° or less, preferably 25° or more and 35° or less.

The base 30 has a base suction means 33. The base suction means 33 is connected to a nozzle 45 of an index table 40, which will be described later. The base suction means 33 can suction air. The base suction means 33 suctions air, thereby suctioning air from the nozzle 45.

Furthermore, the base 30 has a moving means 35 that blows out air. In the illustrated example, the moving means 35 blows air to the moving position P1 using an air nozzle and an air blow device. By blowing out air from the moving means 35, the workpiece 100 is pushed out of the storage section 40a of the index table 40 at the moving position P1, which will be described later, and moves to the taping position P2. Preferably, the moving means 35 is also capable of sucking air. By suctioning air by the moving means 35, it is possible to generate a flow of air from the taping position P2 to the moving position P1 in the work path R.

Furthermore, the base 30 includes a workpiece holding magnet 37 for holding the workpiece 100 in the storage portion 40a of the index table 40. The workpiece holding magnet 37 can attract the workpiece 100 containing a magnetic material by magnetic force. The workpiece holding magnet 37 prevents the workpiece 100 from unintentionally leaving the housing portion 40a. In the example shown in FIG. 4, the workpiece holding magnet 37 is located inside the base 30 and directly below the movement position P1.

FIG. 4 shows a top view of the index table 40. The index table 40 transports the workpieces 100 individually. The index table 40 is provided on the base 30. Since the base 30 has the inclined surface 31, the index table 40 is also arranged along the inclined surface 31 so as to be inclined with respect to the horizontal direction. As shown in FIG. 4, the index table 40 is provided with a plurality of accommodating portions 40a for accommodating the workpieces 100. In the illustrated example, the index table 40 is circular, and accommodating portions 40a are provided at equal intervals along the outer periphery. The diameter of the index table 40 is, for example, 60 mm or more and 80 mm or less. The index table 40 is rotatable with respect to the base 30 around its center. By rotating the index table 40, the workpiece 100 accommodated in the accommodation section 40a can be transported. In addition, as the index table 40 rotates, the storage section 40a in which the workpiece 100 is stored reaches the movement position P1 from which the workpiece 100 is released.

Each of the storage units 40a can accommodate one workpiece 100. The dimensions of the accommodating portion 40a are appropriately set depending on the workpiece 100 to be accommodated, but for example, the length of the index table 40 in the diametrical direction is 0.6 mm or more and 2.0 mm or less, and the length in the circumferential direction is 0.6 mm or more and 2.0 mm or less. It is a substantially rectangular recess with a size of 38 mm or more and 1.5 mm or less. Further, the interval between the accommodating portions 40a along the outer circumferential direction of the index table 40 is, for example, 2.2 mm or more and 4.4 mm or less.

The index table 40 has a nozzle 45. The nozzle 45 is connected to the housing section 40a. As the base suction means 33 suctions air, each accommodating portion 40a is evacuated via the nozzle 45. Since each housing section 40a is evacuated, the workpiece 100 is sucked into and housed in the housing section 40a.

Further, the index table 40 is provided adjacent to the tape passage 25. The index table 40 releases the workpiece 100 from the storage section 40a at a moving position P1 where the storage section 40a in which the workpiece 100 is stored is closest to the tape path 25. The released workpiece 100 is supplied to the cavity 10a of the carrier tape 10 at the taping position P2 in the taping section 50. The index table 40 is arranged above the carrier tape 10 and the tape passage 25 in the vertical direction so that the released workpiece 100 moves by gravity on the inclined surface 31 and is supplied to the carrier tape 10 passing through the tape passage 25. ing.

The index table 40 has a magnetization probe 47 that magnetizes the workpiece 100. In the example shown in FIG. 4, the magnetization probe 47 is a part of the periphery of the index table 40 and is provided on the base 30 side. The magnetization probe 47 magnetizes the work 100 before the work 100 is transported to the movement position P1. Further, the magnetization probe 47 magnetizes the work 100 so that the work 100 is appropriately inserted into the cavity 10a by a work insertion magnet 60, which will be described later. When the magnetization probe 47 and the workpiece 100 approach or come into contact with each other, the magnetic body 101 of the workpiece 100 is magnetized.

Furthermore, a characteristic measuring section (not shown) may be provided around the index table 40. The characteristic measuring section measures the characteristics of the works 100 individually accommodated in the accommodating section 40a. When the characteristic measurement section determines that the characteristics of the workpiece 100 are poor, the workpiece 100 is ejected from the storage section 40a by an unillustrated ejection function before the storage section 40a reaches the movement position P1 from which the workpiece 100 is ejected. be done. The workpiece 100 is ejected from the storage section 40a by ejecting an air flow into the storage section 40a from, for example, an additional air nozzle (not shown). As a result, only the workpieces 100 whose characteristics have been measured to be good are supplied from the index table 40 to the carrier tape 10.

The taping unit 50 supplies the workpiece 100 released from the index table 40 to the carrier tape 10 located in the tape path 25, and inserts it into the cavity 10a. As shown in FIG. 1, the taping portion 50 is provided to overlap a portion of the index table 40 and a portion of the carrier tape 10. More specifically, the taping section 50 is provided so as to overlap the housing section 40a at the moving position P1 and the taping position P2. The taping portion 50 covers the moving position P1 and the taping position P2. FIG. 5 shows an enlarged top view of the taping device 1 at a position where the taping section 50 is provided. Further, FIG. 6 is a cross-sectional view taken along the line VI-VI shown in FIG. As shown in FIGS. 5 and 6, the taping portion 50 has a guide surface 51. As shown in FIGS. The guide surface 51 functions as a guide surface that guides the workpiece 100 released from the index table 40 to the cavity 10a. Guide surface 51 extends between index table 40 and carrier tape 10. The guide surface 51 extends from the moving position P1 to the taping position P2. The inclined surface 31 of the base 30 and the guide surface 51 of the taping part 50 form a work path R from the movement position P1 to the taping position P2. The workpiece 100 is moved linearly along the workpiece path R from the movement position P1 to the taping position P2 by being pushed by gravity and air as air is ejected from the moving means 35.

The guide surface 51 includes a side guide surface 51a shown in FIG. 5 and an upper guide surface 51b shown in FIG. 6. The horizontal direction is the normal direction of the side guide surface 51a, and the upper guide surface 51b extends parallel to the inclined surface 31 of the base 30. The side guide surface 51a is a surface that serves as a reference for driving the carrier tape 10 and arranging the cavity 10a at the taping position P2. Therefore, the cavity 10a is arranged in alignment with the side guide surface 51a when the workpiece 100 is inserted.

The upper guide surface 51b includes a surface parallel to the cavity 10a of the carrier tape 10 at the taping position P2. In other words, the upper guide surface 51b includes a horizontal surface at a position facing the cavity 10a. In the example shown in FIG. 6, the corner of the taping portion 50 is located at the taping position P2. By chamfering the corners of the taping portion 50 at the taping position P2, a surface parallel to the cavity 10a of the carrier tape 10 is formed.

At least a portion of the taping section 50 is transparent so that the imaging device 80 can capture an image through the taping section 50. Specifically, the taping portion 50 is transparent in the portion that overlaps the taping position P2. This allows the imaging device 80 to image the taping position P2 via the taping section 50. That is, the imaging device 80 can image the cavity 10a of the carrier tape 10 located at the taping position P2. At least a portion of the transparent taping portion 50 is made of a material that transmits visible light, such as a glass material.

Further, the taping part 50 is provided with an air intake hole 53 that enables ventilation between the work path R and the outside of the taping part 50. When air is sucked from the work path R by the pump means 70, the air flows into the work path R from the air intake hole 53. As a result, an air flow is formed in the work path R from the moving position P1 to the taping position P2. The work 100 moves along the work path R by riding this air flow.

Pulley 55 positions carrier tape 10 in the proper position. The pulley 55 is arranged facing the taping part 50. Preferably, the pulley 55 is arranged vertically below the taping position P2. The pulley 55 has a substantially disk shape and is rotatable around its center. The pulley 55 has a drive section (not shown), and can be rotated by being driven by this drive section.

The pulley 55 has a plurality of feed teeth (not shown) arranged at equal intervals around its outer periphery. The feed dog engages with a plurality of feed holes 10b provided in the carrier tape 10. By engaging the feed dog with the feed hole 10b, the position of the carrier tape 10 can be slightly moved relative to the pulley 55. In this way, the carrier tape 10 can be appropriately positioned with respect to the pulley 55. In particular, the position of the carrier tape 10 relative to the pulley 55 in the direction orthogonal to one direction d1 can be set as an appropriate position. The spacing along the outer periphery of the feed dog pulley 55 corresponds to the spacing between the feed holes 10b of the carrier tape 10. Even if one feed dog separates from the feed hole 10b of the carrier tape 10, another feed dog engages with another feed hole 10b. That is, at least one feed dog remains engaged with the feed hole 10b of the carrier tape 10. By sequentially engaging the feed teeth and the feed holes 10b, the rotational drive of the pulley 55 can be transmitted to the carrier tape 10, and the carrier tape 10 can be driven.

The workpiece insertion magnet 60 uses magnetic force to pull down the workpiece 100 containing the magnetic material to the bottom of the cavity 10a at the taping position P2. Further, in order to properly insert the workpiece 100 into the cavity 10a, the workpiece insertion magnet 60 is moved in the direction in which the workpiece 100 of the cavity 10a of the carrier tape 10 is to be inserted, for example, in the longitudinal direction of the cavity 10a, in other words, in one direction d1. They are arranged to form magnetic fields along orthogonal directions. In the example shown in FIG. 6, the workpiece insertion magnet 60 is arranged such that the first moving magnet 61 is placed on the side of the moving position P1 from the taping position P2, and the first moving magnet 61 is placed on the opposite side of the moving position P1 from the taping position P2. and a second moving magnet 62. In other words, the first moving magnet 61 and the second moving magnet 62 are arranged such that the taping position P2 is located between them when viewed from above. The first moving magnet 61 and the second moving magnet 62 are arranged vertically below the tape path 25, that is, below the taping position P2. Further, the magnetic pole on the side of the first moving magnet 61 facing the second moving magnet 62 is different from the magnetic pole on the side of the second moving magnet 62 facing the first moving magnet 61. In other words, the first moving magnet 61 and the second moving magnet 62 are arranged so that their different magnetic poles face each other. The distance between the first moving magnet 61 and the second moving magnet 62 is, for example, 2 mm or more and 3 mm or less. By appropriately spacing the first moving magnet 61 and the second moving magnet 62, an appropriate magnetic field can be formed in the cavity 10a. The workpiece insertion magnet 60 is, for example, a neodymium magnet.

During transport, the workpiece holding magnet 65 holds the workpiece 100 inserted into the cavity 10a of the carrier tape 10 by the magnetic force of the workpiece insertion magnet 60 at a position apart from the taping position P2. The workpiece 100 is maintained in the cavity 10a by suppressing it from jumping out from inside the cavity 10a and from tilting within the cavity 10a. In particular, the workpiece holding magnet 65 during transportation maintains the workpiece 100 inserted into the cavity 10a adjacent to the cavity 10a at the taping position P2 in the cavity 10a. The workpiece holding magnet 65 during transportation is arranged below the tape path 25 in the vertical direction.

The pump means 70 is connected to the work path R through the cavity 10a of the carrier tape 10, and sucks air from the work path R. The pump means 70 is connected to the work path R at the taping position P2. The suction of air by the pump means 70 causes an air flow in the work path R from the movement position P1 to the taping position P2. In particular, when air is ejected from the moving means 35 and sucked by the pump means 70, air flows from the moving position P1 to the taping position P2 in the work path R. This air flow allows the workpiece 100 to be easily moved from the movement position P1 to the taping position P2. The pump means 70 is, for example, a vacuum pump.

The imaging device 80 images a part of the carrier tape 10 via the taping section 50. The imaging device 80 images the taping position P2. That is, the imaging device 80 images the cavity 10a of the carrier tape 10 into which the work 100 is inserted at the taping position P2. The imaging device 80 images the cavity 10a after the carrier tape 10 is driven and before the workpiece 100 is supplied to the cavity 10a.

Next, an example of the operation of the taping device 1 and the workpiece insertion stabilizing device 20 of this embodiment will be described. That is, an example of the taping method for the workpiece 100 will be explained.

First, the carrier tape 10 is wound around a supply reel 11 and then wound onto a take-up reel 12. By rotationally driving the take-up reel 12, the carrier tape 10 is driven in one direction d1. The carrier tape 10 is driven in one direction d1 so that the cavity 10a is placed at the taping position P2 so that the workpiece 100 can be inserted into the cavity 10a.

The pulley 55 is arranged to face the taping portion 50, and its feed teeth engage with the feed hole 10b of the carrier tape 10. When the carrier tape 10 is driven, the pulley 55 rotates. The feed teeth of the pulley 55 sequentially engage the feed holes 10b of the carrier tape 10. When the feed dog engages with the feed hole 10b, the carrier tape 10 moves slightly relative to the pulley 55. Thereby, the position of the carrier tape 10 with respect to the pulley 55, especially the position in the direction perpendicular to the one direction d1, is maintained appropriately.

On the other hand, a plurality of works 100 are supplied to the parts feeder 21. The plurality of works 100 are moved as the vibration device of the parts feeder 21 vibrates, so that the works 100 are fitted into the grooves 21a. As a result, the workpieces 100 are aligned in the same direction. The aligned works are sent to the linear feeder 22. The linear feeder 22 transports the works 100 and individually supplies the oriented works 100 to the index table 40 .

The index table 40 accommodates the workpieces 100 individually in the accommodation section 40a while being rotationally driven. The workpiece 100 is accommodated in the accommodation section 40a by being attracted to each accommodation section 40a by being evacuated. As the index table 40 is rotationally driven, the accommodation section 40a that accommodates the workpiece 100 reaches a moving position P1 overlapping the taping section 50, as shown in FIG. At the moving position P1, the work 100 is attracted by the work holding magnet 37, so the work 100 does not move along the inclined surface 31 of the base 30 due to gravity until air is blown out from the moving means 35. Note that the magnetic body 101 included in the workpiece 100 is magnetized by the magnetization probe 47 before reaching the movement position P1.

Next, the pump means 70 connected to the taping position P2 sucks air from the work path R from the taping position P2 through the cavity 10a of the carrier tape 10. By suctioning the air in the workpiece path R, air from the outside flows into the workpiece path R from the air intake hole 53. Thereby, in the work path R, air flows from the movement position P1 to the taping position P2. Further, the accommodation section 40a is evacuated by the base suction means 33 through the nozzle 45, and the workpiece 100 is accommodated in the accommodation section 40a. Further, air is ejected from the moving means 35 of the base 30 to the storage section 40a located at the movement position P1, so that the workpiece 100 is ejected from the storage section 40a located at the movement position P1. The released workpiece 100 moves along the inclined surface 31 while being guided by the guide surface 51 on the flow of air from the moving position P1 to the taping position P2, and reaches the taping position P2.

The workpiece 100 that has reached the taping position P2 is pulled down to the bottom of the cavity 10a of the carrier tape 10 by the magnetic field generated by the workpiece insertion magnet 60. When the work 100 is inserted into the cavity 10a, it is received and inserted into the cavity 10a.

When it is confirmed from the image captured by the imaging device 80 that the workpiece 100 has been inserted into the cavity 10a located at the taping position P2, the carrier tape 10 is driven in one direction d1. As a result, the cavity 10a, which was located on the upstream side in one direction d1 and into which the workpiece 100 is not inserted, is placed at the taping position P2. On the other hand, the cavity 10a into which the workpiece 100 is inserted is located on the downstream side in one direction d1. A magnet 65 for holding the workpiece during transportation is arranged vertically below the cavity 10a into which the workpiece 100 is inserted. Therefore, the workpiece 100 inserted into the cavity 10a is attracted to the workpiece insertion magnet 60, and is prevented from jumping out of the cavity 10a or tilting within the cavity 10a. In other words, the workpiece 100 inserted into the cavity 10a can be maintained in the cavity 10a by the workpiece holding magnet 65 during transportation.

Note that if an abnormality is confirmed in the image of the taping position P2 captured by the imaging device 80, such as that the workpiece 100 is not inserted correctly into the cavity 10a, the pump means 70 interrupts suction of air, and the base The stand suction means 33 sucks air. As a result, in the work path R, air flows from the taping position P2 to the movement position P1. This air flow allows the work 100 to be moved from the taping position P2 to the moving position P1. Thereafter, the moving means 35 blows out air again, and the pump means 70 sucks air, so that air flows from the moving position P1 to the taping position P2 in the work path R. This air flow allows the work 100 to be moved to the taping position P2 again. By doing so, if the work 100 is not inserted correctly into the cavity 10a, the process of inserting the work 100 into the cavity 10a can be redone.

By repeating the above steps, the workpiece 100 can be inserted into each of the plurality of cavities 10a of the carrier tape 10.

While inserting the workpiece 100 into each of the plurality of cavities 10a, a top tape (not shown) for sealing the cavities 10a is attached to the carrier tape 10, and the workpiece 100 is wound onto the take-up reel 12 and collected. As described above, the workpiece 100 is inserted into the cavity 10a of the carrier tape 10 by the taping device 1 and the workpiece insertion stabilizing device 20. That is, the carrier tape 10 to which the workpiece 100 is taped is manufactured.

By the way, in a conventional taping device, a part of the workpiece, for example, an electrode of the workpiece, protrudes from the cavity while the workpiece is inserted into the cavity. If the carrier tape is driven with a part of the workpiece protruding from the cavity, the workpiece may collide with other members of the taping device, or other impact may be applied. Workpieces that are subjected to impact may suffer problems such as damage or failure. When a defect occurs in the workpiece, the carrier tape into which the workpiece is inserted becomes defective, which deteriorates the productivity of the carrier tape.

On the other hand, in the workpiece insertion stabilizing device 20 of this embodiment, the pump means 70 sucks air through the cavity 10a. Therefore, the workpiece 100 can be stably inserted into the cavity 10a. Moreover, the workpiece 100 is made horizontal by the horizontal surface of the upper guide surface 51b. That is, the work 100 becomes parallel to the cavity 10a. Further, the workpiece 100 is pulled down to the bottom of the cavity 10a by the workpiece insertion magnet 60. From the above, when inserting the work 100 into the carrier tape 10, the behavior of the work 100 can be stabilized. Furthermore, since impact is less likely to be applied to the workpiece 100, it is possible to prevent the workpiece 100 from being damaged or malfunctioning. Therefore, deterioration in productivity of the carrier tape into which the workpiece is inserted can be suppressed.

Further, the inclined surface 31 is inclined at an angle of 20° or more and 40° or less with respect to the horizontal direction. With such a sufficiently large inclination angle, the workpiece 100 can be easily moved along the inclined surface 31 because it receives gravity along the inclined surface 31 that is larger than the frictional force from the inclined surface 31.

Further, a workpiece insertion magnet 60 is arranged to form a magnetic field at the taping position P2. Work 100 includes a magnetic material. Therefore, the work 100 can be inserted into the cavity 10a by being attracted by the magnetic field at the taping position P2. Therefore, when the work 100 is inserted into the carrier tape 10, the behavior of the work 100 can be made more stable.

In particular, the workpiece insertion magnet 60 includes a first moving magnet 61 placed on the side of the moving position P1 from the taping position P2, and a second moving magnet 62 placed on the opposite side of the moving position P1 from the taping position P2. The magnetic pole of the first moving magnet 61 on the side facing the second moving magnet 62 is different from the magnetic pole of the second moving magnet 62 on the side facing the first moving magnet 61. According to this arrangement of the workpiece insertion magnet 60, an appropriate magnetic field can be formed at the taping position P2. According to the magnetic field formed in this way, the workpiece 100 supplied to the taping position P2 can be inserted into the cavity 10a. Therefore, when the work 100 is inserted into the carrier tape 10, the behavior of the work 100 can be made more stable.

Further, a magnet 65 for holding the workpiece during transportation is arranged at a position adjacent to the taping position P2 and below the cavity 10a in the vertical direction into which the workpiece 100 is inserted. During transportation, the workpiece holding magnet 65 maintains the workpiece 100 in the cavity 10a. This prevents the workpiece 100 inserted into the cavity 10a from jumping out of the cavity 10a or tilting within the cavity 10a due to other magnets, particularly the workpiece insertion magnet 60. That is, the behavior of the workpiece 100 inserted into the carrier tape 10 can be stabilized.

Furthermore, the base 30 has a workpiece holding magnet 37 for holding the workpiece 100 in the housing portion 40a. Since the workpiece 100 includes a magnetic material, the workpiece 100 can be held in the housing portion 40a by the magnetic force of the workpiece holding magnet 37. Thereby, it is possible to effectively prevent the workpiece 100 from falling unintentionally from the storage section 40a.

The first moving magnet 61 is disposed on the side of the moving position P1, and the second moving magnet 62 is disposed on the opposite side of the moving position P1 from the taping position P2. The magnetic pole on the side facing the second moving magnet 62 is different from the magnetic pole on the side facing the first moving magnet 61 of the second moving magnet 62, and the magnetic pole on the side opposite to the first moving magnet 61 is located in the cavity in which the workpiece 100 is inserted at a position adjacent to the taping position P2. It further includes a magnet 65 for holding the work during transportation, which is disposed below the cavity 10a in the vertical direction and maintains the work 100 in the cavity 10a. According to the workpiece insertion stabilizing device 20, the workpiece 100 can be moved from the movement position P1 to the taping position P2 by blowing out air from the moving means 35. In particular, the workpiece insertion magnet 60 and the workpiece holding magnet 65 during transportation can stabilize the behavior of the workpiece 100 when and while the magnetized workpiece 100 is inserted into the carrier tape 10.
