Description

  The present invention relates to an electronic device alignment apparatus and alignment method for aligning polar electronic components in a predetermined direction.

  In an electronic component (work, chip) having a polarity such as an LED chip or an inductor chip, it is necessary to align the polarities in a predetermined direction. The polarity alignment of the electronic components is performed by an alignment device, and the polarity-aligned electronic components are stored in, for example, a recess of the embossed tape, and the embossed tape covered with the cover tape is wound around a reel and sent to the next process. .

  As an electronic component aligning device, a storage groove that opens radially outward and extends in the radial direction is formed on the outer peripheral edge of the turntable (index table) by separating by a predetermined angle (intermittent feed of the turntable). A configuration is known in which parts are stored in a storage groove and sent, and the polarity of an electronic component whose polarity is not oriented in a predetermined direction is aligned and aligned in a predetermined direction by an inversion table (for example, Japanese Patent Application Laid-Open No. 08-236898). Publication).

In the electronic component aligning apparatus, stations such as a supply station, an inspection station, a reversing station, a discharge station, and a packing station are set around the turntable in response to intermittent feed of the turntable.
First, in the supply station, the electronic components are supplied from the vibrating parts feeder to the turntable, for example, regardless of the direction of polarity, and are supplied in an upward direction in a daisy chain, and the storage groove on the outer periphery of the turntable. Are sequentially stored. The parts feeder has a linear feeder provided between the hook-shaped main body and the turntable, and the electronic parts are supplied from the tip of the linear feeder to the turntable and stored in the storage groove.

  In the state where it is stored in the storage groove on the outer peripheral edge of the turntable, the electronic component is sent from the supply station to another station provided around the turntable along with the intermittent feed of the turntable. The polarity direction and electrical characteristics of the test are inspected and determined. The electronic components determined to have the polarity direction not in the predetermined direction are aligned in the predetermined direction with the polarity direction reversed (turned 180 °) at the reversing station. Electronic components that are misaligned despite being to be aligned or electronic components that are judged to have poor electrical characteristics (NG) at the inspection station are eliminated at the next exclusion station, and those that are aligned in polarity are packed at the packing station. Are sequentially stored in the recesses of the embossed tape, and the embossed tape is covered with a cover tape and wound on a reel.

  In the inspection station, reversing station, discharge station, and packing station set around the turntable, the most time-consuming process is the reversal and alignment of the polarity at the reversing station. Is desired from the viewpoint of speeding up the turntable feed.

  To describe in detail the reversal and alignment of the polarity of the electronic components in the reversing station, the reversing table is arranged in the reversing station around the turntable, and the reversing groove with the same cross-sectional shape communicating with the storage groove on the outer periphery of the turntable is reversed. Formed on the table.

  When an electronic component determined by the inspection station that the polarity direction is not in the predetermined direction reaches the reversing station by intermittent feed of the turntable, the electronic component is fed from the storage groove on the outer periphery of the turntable to the reversing groove of the reversing table. When the electronic component is fed into the reversing groove, the reversing table is rotated by 180 °, thereby reversing the direction of the electronic component in the reversing groove and aligning the polarities thereof in a predetermined direction. The aligned electronic components are sent out (returned) from the reverse groove of the reverse table to the storage groove on the outer periphery of the turntable.

For electronic components that have been inspected as having a polarity in a predetermined direction (an electronic component that has already been aligned), it is not necessary to invert and align at the reversing station, so even if the electronic component reaches the reversing station. The electronic parts are not transferred between the storage groove on the outer periphery of the turntable and the reversing groove of the reversing table .

  In this way, in the reversing station, the polarity of the electronic components is reversed and aligned using the reversing table, and the electronic components are transferred between the receiving groove on the outer periphery of the turntable and the reversing groove of the reversing table (feeding in, The sending (returning) is performed, for example, by flowing air between the storage groove on the outer periphery of the turntable and the reversing groove of the reversing table, and sliding the electronic components under the airflow.

In the configuration where the electronic parts are picked up and delivered to the pick-up arm, the pick-up arm rises after picking up, rotates and then descends, and the electronic parts move long and fall while moving in the air. There is a risk.
On the other hand, the delivery of electronic components by slide is a parallel movement in the horizontal plane between the storage groove on the outer periphery of the turntable and the reversing groove of the reversing table on the same plane, and the electronic components fall during delivery. This is not the case, and since the moving distance is short, the electronic components can be quickly reversed and aligned at the reversing station. As a result, the turntable can be fed at a high speed, a series of processes from the supply of electronic components to the reversal and alignment to packing on the embossed tape can be performed at high speed, and high productivity can be secured.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 are a schematic plan view of an electronic component alignment apparatus according to an embodiment of the present invention, and a flowchart of a series of processes in the electronic component alignment apparatus.
As shown in FIG. 1, the electronic component aligning apparatus 10 includes a turntable 12 that is intermittently fed, and an electronic component having a polarity such as an LED chip or an inductor chip is supplied from a parts feeder 14 to the turntable. The table is configured so that the polarities of the electronic components are aligned in a predetermined direction so that the polarities are aligned. For this purpose, a plurality of stations are set.

In the embodiment, the inspection, discharge, and packing processes are performed separately around the turntable and at a position away from the turntable, and an inspection, discharge, and packing station is set at a position away from the turntable. ing.
That is, in the embodiment, as shown in FIG. 1, the five stations of the supply station A, the inspection station B1, the reversing station C, the discharge station D1, and the packing station E1 are located at positions corresponding to the intermittent feed of the turntable 12. In addition, three stations, another inspection station B2, a discharge station D2, and a packing station E2, are set at positions away from the turntable.

  A series of processes in the present invention will be described with reference to the flowchart of FIG. 2. First, an electronic component having polarity is supplied from the parts feeder 14 to the turntable 12 at the supply station A. For example, the wavelength of the supplied electronic component is inspected in the inspection station B1, and the direction of polarity and the quality of the electrical characteristics are determined. The direction of the electronic component whose polarity is not in a predetermined direction is inverted in the inversion station C. The polarities are aligned and aligned in a predetermined direction. Electronic components whose characteristics (electrical characteristics) are determined to be defective from the inspection of the wavelength of the inspection station B1 are discharged and collected at the discharge station D1. And the embossing tape 28a is supplied in the packing station E1, and an electronic component is stored in the recess of an embossing tape.

The embossed tape 28a extends in a direction away from the turntable 12, and an inspection station B2 , a discharge station D2, and a packing station E2 are provided along the embossed tape. First, due to an inspection or determination error at the inspection station B1. The presence / absence of electronic components whose polarities are not aligned is inspected by image processing at the inspection station B2. If there is an electronic component determined to be misaligned from the image processing of the external shape of the electronic component, it is discharged and collected at the discharge station D2. Then, the cover tape is supplied at the packing station E2 and is put on the embossed tape 28a, and is thermocompression bonded to seal the recess of the embossed tape, and the embossed tape covered with the cover tape is wound around the reel and a series of The process ends.

  The supply station A, inspection station B1, reversing station C, discharge station D1, and packing station E1 around the turntable 12 include a push-up member 20, inspection means 22, reversing table 24, discharge means 26 for corresponding processing. The packing means 28 are respectively arranged.

3A and 3B are a plan view and a cross-sectional view in which a part of the turntable and parts feeder in the supply station are broken. 4 (A) to 4 (C) are enlarged views of part A of FIG. 3 (B), and show the storage process of the electronic component in the storage groove in the supply station.
3A and 3B, the storage grooves 12a for storing the electronic components W are separated from each other in the circumferential direction by an angle corresponding to the intermittent feed of the turntable on the outer peripheral edge of the turntable 12. It is formed, and the storage groove has an extraction window shape penetrating the turntable. For example, if the intermittent feed of the turntable 12 is 7.5 °, 48 storage grooves 12a are formed on the outer periphery of the turntable so as to be separated from each other in the 7.5 ° circumferential direction. In the embodiment, the outer shape of the electronic component W is rectangular, and the storage groove 12a is a rectangular extraction window that is slightly larger than the outer dimension of the electronic component and whose longitudinal direction is located in the radial direction.

  Since the stored electronic component W may fall out of the storage groove 12a having the extraction window shape, the upper surface of the support disk 13 on which the turntable 12 is rotatably mounted so that the upper surface covers the storage groove 12a. It is formed with almost the same diameter as the turntable. Therefore, the electronic component in the storage groove 12a is slid on the support disk along with the intermittent feed of the turntable without falling out of the storage groove.

  In the present invention, since the delivery of the electronic components is performed in the vertical direction, in the supply station A and the reversing station C that deliver the electronic components, as will be described later, a part of the support disk 13 is cut away and the push-up member 20. An inversion table 24 is arranged around the turntable 12 to allow electronic components to be delivered in the vertical direction.

  The parts feeder 14 is a vibration type, and has a linear feeder 14b in addition to the hook-shaped main body 14a. From the rear of the parts feeder main body, the electronic component W is oriented upward and the direction of the shape is adjusted regardless of the polarity direction. It is pushed and sent to the rosary chain.

  In the linear feeder 14b of the parts feeder, a U-shaped cross-sectional passage 14b1 for supplying the electronic component W is formed just below the storage groove 12a (12a1) located in the supply station A. Further, the stopper piece 14b2 extends from the front end of the linear feeder 14b beyond the storage groove 12a1 located at the supply station A so as to sink under the outer periphery of the turntable. Is located at the end of the passage 14b1.

  As can be seen from FIG. 4A, the bottom of the linear feeder passage 14b1 is just below the storage groove 12a1 just before the stopper end 14b2 'of the stopper piece. In the supply station A, the storage groove 12a1, the passage with the bottom removed, and the push-up member are positioned in a substantially aligned relationship.

The push-up member 20 pushes up and stores the electronic component W supplied from the parts feeder 14 to the turntable 12 in the storage groove 12a1 on the outer periphery of the turntable located at the supply station. A portion is cut out and arranged around the turntable 12 below the storage groove 12a1.
That is, the push-up member 20 is arranged below the storage groove 12a1 of the supply station so as to be able to move up and down. The push-up member has a suction hole 20a on its upper surface, and a negative-pressure air flow path communicating with the suction hole. 20b is formed in the axial direction.

  The electronic component W is pushed from behind the linear feeder passage 14b1 from the parts feeder main body 14a and sent to the rosary chain. When the leading electronic component is pushed and reaches the passage portion where the bottom is removed, the push-up member As shown in FIG. 4A, the push-up member waits at a position where the upper surface thereof is substantially flush with the bottom surface of the passage.

  It is sufficient that the push-up member 20 is provided so as to be movable up and down, and the push-up member 20 may be provided on the linear feeder 14b of the parts feeder so as to be movable up and down, or a support member that supports the push-up member so as to be movable up and down may be provided separately from the linear feeder. .

  When the leading electronic component W (W1) reaches the passage portion where the bottom is removed and rides on the upper surface of the push-up member 20, it is still pushed and sent, as shown in FIG. 3B, the stopper end 14b2 of the stopper piece. The electronic component is positioned in alignment with the storage groove 12a1 of the supply station, while being blocked on the upper side of the push-up member.

When the sensor or the like detects that the leading electronic component W1 is in a predetermined position (position where the hand going to the stopper end 14b2 ′ is blocked and aligned with the storage groove 12a1), negative pressure air acts on the flow path 20b of the push-up member. Then, an adsorption force is generated in the adsorption hole 20a on the upper surface, and the electronic component W is adsorbed on the upper surface. Then, the push-up member 20 is lifted while the electronic component W2 is adsorbed on the upper surface, and the electronic component is pushed up and stored in the storage groove 12a1 located in the supply station. When the electronic component is pushed up and stored in the storage groove 12a1, the turntable 12 is intermittently fed, and the electronic component is slid and sent on the support disk while being stored in the storage groove, and leaves the supply station A.
In addition, since it will become an obstacle of the intermittent feed of the turntable 12 if it raises until the pushing-up member 20 enters in the accommodation groove 12a1, it goes without saying that the pushing-up member does not enter the accommodation groove.

  As described above, delivery of the electronic component W (W1) at the supply station A, that is, storage from the parts feeder 14 to the storage groove 12a (12a1) on the outer periphery of the turntable is performed in the vertical direction by the lifting and lowering operation of the push-up member 20. Therefore, the electronic component can be delivered in the vertical direction regardless of the size of the electronic component in the longitudinal direction. Usually, the thickness (size in the vertical direction) of the electronic component is thin and the distance required for delivery is small, so that the delivery of the electronic component at the supply station can be performed in a short time.

The push-up member 20 pushes up the electronic component while being sucked by the suction hole 20a on the upper surface thereof and stores it in the storage groove, so that the electronic component is prevented from shifting during the push-up (delivery). Are supplied and stored accurately.
The storage groove 12a is formed in the shape of the extraction window and has a shoulder 12a-1 radially outward (see FIG. 3A), and this shoulder prevents the electronic component W from popping out due to centrifugal force. Function as. Therefore, it is not necessary to provide a guard on the support disk 13 for preventing the electronic component from jumping out of the storage groove 12a, and the configuration is simplified.

  Further, the electronic member W1 can be pushed up and stored in the storage groove 12a by the push-up member 20 only by raising the push-up member by a predetermined distance, and the electronic component is delivered (pushed up) without being applied to the stopper. There is no risk of damage to electronic components. The electronic components are moved up and down by adsorbing the electronic components, and the electronic components are not displaced during delivery, so that delivery at the supply station A can be performed at high speed.

  When the turntable 12 is intermittently fed and the storage groove 12a1 located at the supply station A is separated from the supply station, the push-up member 20 is at an initial position where the upper surface thereof is substantially flush with the bottom surface of the passage (see FIG. 4A). ), And the next electronic component W ′ is pushed and sent to a position where it stops on the stopper end 14 b 2 ′ of the stopper piece and stays on the upper surface of the push-up member 20. Then, the next storage groove 12a 'adjacent to the upstream side (see FIG. 3A) reaches the supply station A aligned with the electronic component W' under the intermittent feed of the turntable 12. The push-up member 20 is lifted and lowered using, for example, a cam.

Although not shown, the electronic component aligning apparatus 10 includes a central processing circuit (CPU), and an operation necessary for storing (pushing up) the electronic component into the storage groove in the supply station A, that is, detection of the electronic component W1 by the sensor. A series of processes such as the action of negative pressure air, the raising of the push-up member 20, the intermittent feed of the turntable, and the lowering of the push-up member are automatically and continuously performed under the control of the central processing circuit.
The central processing circuit also controls the movement of all the components of the electronic component aligning apparatus 10, that is, the inspection means 22, the reverse table 24, the discharge means 26, the packing means 28, and the like, which will be described later.

  The electronic component W stored in the storage groove 12a on the outer peripheral edge of the turntable is sent to the inspection station B1 set on the downstream side of the supply station A, and the polarity direction and electrical characteristics are inspected by the inspection means 22 provided in the inspection station. Is inspected. For example, the inspection means 22 is composed of a tester disposed around the turntable 12, and a terminal (tester terminal) extending from the tester contacts the terminal of the electronic component W, so that the electronic device is stored in the storage groove. The component's wavelength is measured to inspect the polarity direction and electrical characteristics.

  Next, the electronic component W is sent to the reversing station C, and the direction of the electronic component which is determined by the inspection means 22 as not being in the predetermined direction is reversed by the reversing table 24 so that the polarity of the electronic component is predetermined. Aligned and aligned in the direction. At the reversing station C, electronic components are delivered between the storage groove 12a on the outer periphery of the turntable and the reversing table 24.

  5A and 5B are a plan view and a cross-sectional view of a reversing table in the reversing station, and a turntable partially cut away. In FIG. 5A, the mark m is displayed on the surface of the electronic component in order to distinguish the direction of the polarity of the electronic component, and the direction in which the mark m is located radially inside is assumed to be a predetermined direction. is doing.

As shown in FIGS. 5A and 5B, the reversing table 24 is provided around the turntable 12 with a part of the support disk 13 cut out, and the electronic component W that is housed in the housing groove 12a is sent. When the reversing station C is reached, the electronic component stands by below the turntable at a position where the electronic component is placed on the reversing station C, that is, at a position aligned with the storage groove located at the reversing station C.
That is, the reversing table 24 includes, for example, a cylindrical rotating member 24a that can be rotated, and an elevating member 24b that can be moved up and down in the rotating member, and the upper surface of the elevating member has an adsorption hole 24b1. The negative pressure air flow path 24b2 communicating with the suction hole extends in the axial direction of the elevating member.

  The inner shape of the upper end 24a ′ of the central hole of the rotating member in which the elevating member 24b is arranged to be movable up and down is formed to be slightly larger than the outer dimension of the electronic component so that the electronic component W2 can be lowered. The outer shape of the upper end portion 24b 'of the member is formed to be substantially the same as the outer dimension of the electronic component, for example, so that the electronic component can be placed and the upper end portion 24a' of the central hole of the rotating member can be moved up and down.

The rotating member 24a is rotatably held by the support block 24a2 by two upper and lower ball bearings 24a1, and the lower end thereof is fitted to the roller 24a3 and integrated with the roller. A belt 24a5 is stretched between the motor 24a4 and the roller 24a3.
The electronic component W is rectangular, non-circular, and the upper end portion 24b ′ of the elevating member having a shape corresponding to the electronic component is also non-circular. Therefore, the elevating member 24b disposed in the rotating member 24a is rotated. If the member 24a rotates, it rotates integrally with the rotating member.

6 (A-1) to (A-4) and (B-1) to (B-4) are a turntable partially broken in the reversing station, a plan view and a cross-sectional view of the reversing table. The inversion process in a station is shown.
In the reversing station C, as shown in FIGS. 6 (A-1) and 6 (B-1), the storage groove 12a for storing the electronic component W2 is aligned with the reversing table, and the electronic component in the storage groove is attached to the lifting member 24b. Located on the top surface.

  When the electronic component W2 determined by the inspection means (tester) 22 of the inspection station B1 that the polarity is not directed to the predetermined direction is sent to the reversing station C, negative pressure air is applied to the flow path 24b2 of the lifting member to move up and down. An adsorption force is generated in the adsorption hole 24b1 on the upper surface of the member, and the electronic component W2 is adsorbed on the upper surface of the elevating member 24b. Then, while the electronic component W2 is adsorbed, the electronic component is placed on the upper surface, and the elevating member 24b is lowered to move the electronic component downward from the storage groove 12a as shown in FIGS. 6 (A-2) and (B-2). Take out. Since the elevating member 24b is in a position where the electronic component W is placed on the upper surface thereof, the electronic component can be taken out from the storage groove 12a if it is lowered by a distance slightly larger than the height of the electronic component.

When the electronic component W is taken out from the storage groove 12a, the motor 24a4 is activated, and the driving force of the motor is transmitted to the roller 24a3 via the belt 24a5, and the state shown in FIGS. As shown, the turning member 24a is turned 180 °. When the rotating member 24a is rotated 180 °, the elevating member 24b is rotated 180 ° together with the rotating member with the electronic component W2 placed on the upper surface thereof.

  When the rotating member is rotated 180 °, the motor 24a4 is stopped, and as shown in FIGS. 6A-4 and B-4, the elevating member 24b is raised to push up the electronic member W2 on the upper surface, The member is returned to the storage groove 12a and stored. The electronic component is returned to the storage groove 12a in a state where the mark m of the electronic component is located inward in the radial direction, and the polarity of the electronic component is reversed and aligned and aligned in a predetermined direction.

  When the electronic component W2 is returned to the storage groove 12a with the polar directions aligned, the turntable 12 is intermittently fed and the upstream electronic component W ′ is sent to the reversing station C. As shown in FIG. 6 (A-4), this electronic component W ′ is one in which the mark m is located radially inward and the polarity is determined to be in a predetermined direction in the inspection station B1. Therefore, the reversing process by the reversing table is not performed, and the reversing station C is passed through.

Since the next electronic component W ″ has a mark located radially outward and it is determined at the inspection station B1 that the polarity is not directed in a predetermined direction, A reversal process similar to that for the component W2 is performed.
As shown in FIGS. 6A-1 to 6A-4, the electronic component W that has passed through the reversing station C has its direction aligned, and its polarity is aligned, and is sent to the next station (discharge station D1).

  Electronic parts are transferred from the turntable 12 at the reversing station C to the reversing table 24, that is, the electronic parts are taken out from the storage groove 12a on the outer periphery of the turntable, and the direction of the electronic components is reversed by the reversing table. The parts are returned in the vertical direction by the raising / lowering operation of the elevating member 24b, and the electronic parts can be transferred in the vertical direction regardless of the size of the electronic parts in the longitudinal direction. Since the thickness of the electronic component (the size in the vertical direction) is thin and the distance required for delivery is small, delivery of the electronic component at the reversing station C can be performed in a short time.

Electronic parts can be delivered (removal of electronic parts from the storage groove 12a and return to the storage groove after being reversed) at the reversing station by simply lifting the elevating member by a predetermined distance. Therefore, there is no displacement of electronic parts during delivery, and delivery can be performed as fast as possible.
Note that there is no particular difficulty in rotating the rotation member 24a accurately by 180 °, and the elevating member is rotated 180 ° integrally with the rotation member so that there is no rotation deviation, and the inverted electronic component W Are delivered while being aligned in the storage groove, and there is no possibility that the electronic component contacts the storage groove and is damaged during the delivery.

  The rotating member 24a is intermittently fed by 180 °, but may be continuously rotated in the same direction, or may be rotated alternately in different directions by using the motor 24a4 as a reversible motor.

Electronic components whose electrical characteristics do not satisfy the reference value at the inspection station B1 and whose electrical characteristics are determined to be defective (NG) are removed and collected at the discharge station D1 next to the reversing station C.
That is, a discharge means 26 for removing and discharging the NG electronic components from the storage groove 12a is provided in the discharge station D1 around the turntable. For example, the discharge means 26 is a suction arm that can be rotated and moved up and down, and when an electronic component of NG is sent to the discharge station D1, the suction arm descends to suck the electronic component and rise to remove it from the storage groove. The NG electronic components are recovered in the recovery box by discharging, rotating and descending above the recovery box provided adjacent to the discharge station, and releasing the suction.

Regardless of the suction arm, for example, when an NG electronic component is stored in the storage groove 12a and sent over the upper surface of the support disk 13 to reach the discharge station D1, the upper surface of the support disk 13 is opened to open a drop hole. It is good also as a structure which makes it and makes it fall from the opening (drop hole) and collect | recover in a collection box. The electronic parts can be collected by this pit, for example, when a hinge door-shaped member slightly larger than the electronic parts is arranged on the upper surface of the support disk 13 and the NG electronic parts reach the discharge station D1 and come above it. It can be done by rotating and opening.

  The discharge station D1 may be provided upstream rather than downstream of the reversing station C, that is, between the supply station A and the inspection station B1, and NG electronic components may be discharged and collected before being sent to the reversing station.

  The reversing station C aligns and aligns the directions, and the discharging station D1 discharges the electronic components having poor electrical characteristics, and then the electronic components are sent to the packing station E1. The packing means 28 is arranged around the turntable 12 in the packing station E1, and the electronic component W is stored in the recess of the embossed tape 28a supplied to the packing station by the packing means. The packing means 28 is, for example, a suction arm that is rotatable and can be lifted and lowered like the discharge means 26 of the discharge station D1, and the suction arm descends to suck the electronic components in the storage groove 12a on the outer periphery of the turntable. Then, it rises, pivots on the recess of the embossed tape 28a, and descends. Then, by releasing the suction and storing the electronic component W in the recess of the embossed tape and ascending, the packing means 28 moves the electronic component from the storage groove to the recess of the embossed tape and stores it.

In the embodiment, the process of covering the embossed tape 28a with a cover tape and thermocompression bonding to seal the recess of the embossed tape is performed not at the turntable 12 but at a position away from the turntable.
That is, an inspection station B2, a discharge station D2, and a packing station E2 are provided along the running path of the embossed tape 28a, and the embossed tape 28a is located at a position where the inspection means 122, the discharge means 126, and the packing means 128 are separated from the turntable. It is sequentially arranged along the runway.

For example, the inspection means 122 is an image processing member disposed above the embossed tape 28a, and the image processing member (inspection means) is overlooked by the inspection means 22 by the tester even though the polarity is not in a predetermined direction. The electronic parts sent so far without being reversed at the reversing station C are determined under the image processing. Then, the electronic components that are determined not to be aligned in polarity by the image processing member 122 are discharged from the recess of the embossed tape by the discharge means 126 disposed in the next discharge station D2, and collected. For example, the discharge means 126 of the discharge station D2 is a suction arm similar to the discharge means 26 of the discharge station D1 around the turntable. The discharge means 126 discharges and collects the electronic components in the collection box.

  Since the discharge means 126 is merely aligned in a predetermined direction and is a good product in terms of electrical characteristics, the polarity may be reversed and returned directly to the recess of the embossed tape 28a. If it is not returned to the recess, it is returned to the parts feeder 14.

  When the embossed tape 28a storing the electronic components in the recess is sent to the packing station E2, a cover tape (not shown) is supplied by the packing means 128, and is applied to the embossed tape. The embossed tape that has been sealed and covered with the cover tape is wound around a reel, and a series of processes is completed.

As described above, according to the present invention, since the electronic component is transferred in the reversing station in the vertical direction, the electronic component can be transferred regardless of the size in the longitudinal direction of the electronic component. It can be done in a short time. Therefore, electronic components can be supplied, reversed, and aligned at high speed, and high speed processing is possible.
In addition, the electronic components are delivered at the supply station in the vertical direction, and the delivery at the supply station can be performed in a short time.

  In the conventional configuration in which inversion and alignment are performed by a horizontal slide, for example, processing of 4.5 electronic parts per unit time (one second) is limited, whereas in the present invention, 15 electronic parts are processed. It became possible to process.

  The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations, etc. within the technical scope of the present invention are included in the present invention. Needless to say.

  For example, in the embodiment, the storage groove 12a on the outer periphery of the turntable is formed in a closed extraction window shape. However, it suffices to have a shoulder 12a-1 (see FIG. 3A) that functions as a guard to prevent the electronic components from popping out radially outward, and the storage groove is limited to a closed window shape. It is good also as the extraction window shape of the shape which opened a part of shoulder part.

  In the embodiment, the external shape of the electronic component is rectangular. However, the shape of the electronic component is not limited to the rectangular shape, and the upper surface of the lifting member (and push-up member) of the turntable can adsorb and stack the electronic component. Since the electronic component can be transferred in the vertical direction as long as the shape corresponds to the shape of the electronic component, the present invention can be applied to electronic components having various shapes.

  The present invention can be widely applied to align polarities of various shaped electronic components having polarity.
