Description

  The present invention relates to a work aligning / conveying apparatus that aligns and conveys a work using a rotary feeder, and a work appearance inspection apparatus that captures an image with an imaging camera while aligning and conveying the work using the work aligning / conveying apparatus.

  Electronic devices such as portable information terminals and digital cameras have been reduced in size and thickness by mounting a large number of electronic components at high density. With high-density mounting, the dimensions are becoming smaller and thinner. Similarly, there is an increasing demand for weight reduction in electronic parts used in automobiles and industrial equipment. In addition, depending on the market and application, there is a requirement for quality assurance by 100% inspection, and in the future, the number of varieties that perform 100% inspection will be expanded. These electronic components are commonly called workpieces (or minute workpieces). In this specification, polyhedral shapes such as semiconductor elements, crystal resonators, crystal elements (SMD crystal elements), SAW filter elements, chip capacitors, resistors, coils, terminals, substrates, sheets, films, etc. The electronic component is expressed as a workpiece.

  FIG. 13 is a perspective view illustrating a polyhedral work 20 (21, 22, 23, 24). Reference numeral 20H represents the height (or outer diameter) of the workpiece 20, reference numeral 20W represents the width of the workpiece 20, and reference numeral 20L represents the total length of the workpiece 20. Reference numeral 201 represents the plane of the workpiece 20, reference numeral 202 represents the right side surface of the workpiece 20, reference numeral 203 represents the bottom surface of the workpiece 20, reference numeral 204 represents the left side surface of the workpiece 20, and reference numeral 205 represents the workpiece 20. The front side represents the front side, and the reference numeral 206 represents the back side of the workpiece 20. A workpiece 21 shown in FIG. 13A is a rectangular parallelepiped workpiece such as a chip capacitor or a chip inductor. As the dimensions of the chip capacitor 21, for example, there are parts in which 20H is 0.3 mm, 20W is 0.3 mm, and 20L is 0.6 mm. A workpiece 22 shown in FIG. 13B is a rectangular and thin workpiece such as a semiconductor element. As the dimensions of the semiconductor element 22, for example, there are components in which 20H is 0.05 mm, 20W is 1.0 mm, and 20L is 2.0 mm. A work 23 shown in FIG. 13C is a work in which a convex part is formed on a rectangular part such as an oscillator or a mounting type LED. As the dimensions of the mounting type LED 23, for example, there is a component in which 20H is 0.2 mm, 20W is 0.8 mm, and 20L is 1.6 mm. A workpiece 24 shown in FIG. 13D is a columnar (cylindrical) workpiece such as a terminal used for an IC connector or an optical connector. As the dimensions of the optical connector terminal 24, for example, there are parts in which 20H is 1.7 mm and 20L is 5.0 mm. Examples of the work 20 include mounting components such as a chip capacitor, a semiconductor element, a crystal element, a SAW filter element, a chip resistor, a chip coil, a mounting type LED, a chip IC, an optical connector, a terminal, a pad, and a spacer. . These workpieces 20 may be difficult to conduct an electrical inspection because they are small and fragile, for example, or may be troublesome in appearance inspection because they are cylindrical and have a predetermined length. If this work is assembled, the module and the mounting board will be defective, so an automated appearance inspection before mounting is required. In addition, as for electronic components in general, it is preferable to perform an appearance inspection before mounting in order to increase the yield after mounting.

  In many cases, these workpieces are once packed together in a bulk case and packaged in a rose shape. They are taken out from the bulk case in a random state, visually inspected while being aligned and transported, and screened (quality screening or classification). And moved to the next step. The next process includes a work electrical inspection process, an assembly process for assembling and mounting the work, and a packaging process for taping and stuffing the magazine.

  Examples of known workpiece aligning and conveying apparatuses include a vibratory feeder using vibration and a rotary feeder using centrifugal force. By rotating the rotary feeder at a high speed, the workpiece transfer speed can be increased by about 7 times compared to the vibratory feeder.

The maximum value of the workpiece conveyance speed of the current vibratory feeder (commercially available product) is approximately 6,000 [mm / min]. For example, in the case of a workpiece such as a chip capacitor 21 where 20H is 0.3 mm, 20W is 0.3 mm, and 20L is 0.6 mm, the maximum conveyance number speed is 10,000 [pieces / minute]. Actually, the workpiece cannot be transferred efficiently tail-to-nose and a loss occurs, so the value is smaller than the calculated value. For such thin and small workpieces, the current vibratory feeder is used. However, it satisfies the market demand for workpiece transfer performance.
However, in the case of a workpiece having 20H of 1.7 mm and 20L of 5.0 mm, such as the optical connector terminal 24, the maximum conveyance number speed is 1,200 [pieces / minute]. Actually, the loss occurs in the same way as described above, so the value becomes even smaller than the calculated value. For such relatively long workpieces, the current vibratory feeder clearly lacks workpiece transfer performance. doing.

The maximum value of the workpiece conveyance speed of the current rotary feeder (manufactured by Ishikawa Seisakusho Co., Ltd.) is approximately 40,000 [mm / min]. For example, in the case of a workpiece having 20H of 0.3 mm, 20W of 0.3 mm, and 20L of 0.6 mm, such as the chip capacitor 21, the maximum conveyance number speed is 66,670 [pieces / minute]. Actually, the workpiece cannot be transferred efficiently tail-to-nose, but the calculated value is smaller than the calculated value. However, in the case of such a thin and small workpiece, even the current vibratory feeder can transfer the workpiece. In terms of performance, it fully meets market demands.
However, in the case of a workpiece having 20H of 1.7 mm and 20L of 5.0 mm, such as the optical connector terminal 24, the maximum conveyance number speed is 8,000 [pieces / minute]. Actually, the loss occurs in the same manner as described above, so the value becomes even smaller than the calculated value. In the case of such a relatively long workpiece, the workpiece conveyance performance is improved even with the current rotary feeder. Insufficient for market demand.

  In recent years, imaging cameras and image processing technologies for visual inspection have been dramatically improved in speed and accuracy, and have not been an obstacle to performing high-speed and high-precision visual inspection of workpieces. ing. On the other hand, in order to inspect the entire surface of the workpiece, for example, all six surfaces of a rectangular parallelepiped with high accuracy, an imaging means (imaging camera) is arranged with these workpieces aligned and spaced apart from each other. Although it has to be transported to the image processing unit, the conventional work transport device has already reached the limit of the processing speed. That is, in the case of a relatively long workpiece having a length 20L of 5.0 mm, such as the optical connector terminal 24, the maximum conveyance number speed of the known workpiece alignment / conveying device can be achieved even with a rotary feeder. Is 8,000 [pieces / minute], so it is impossible to determine the appearance at a speed exceeding this value and to determine the appearance.

  Patent Document 1 discloses that a vibratory feeder that aligns and conveys workpieces, a vibration-free relay base that has a conveyance groove that relays and conveys workpieces that are aligned and conveyed from the vibratory feeder, and receives and rotates workpieces from the vibration-free relay stand. A first rotating indexer that conveys; a second rotating indexer that is arranged below the first rotating indexer and that conveys the rotation; and imaging means (imaging camera) that images the workpiece conveyed by these indexers.

Here, the indexer is a work conveyance mechanism having a disk shape and a rotating shaft arranged in the horizontal direction, and the work is air adsorbed by suction holes formed at predetermined intervals on the outer circumference of the disk shape. It is a transport mechanism that rotates and transports around a rotating shaft.

  However, as described above, it is difficult for the conventional workpiece alignment and transport device (workpiece appearance inspection device) to transport the workpiece at a higher speed.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, an object of the present invention is to provide a work alignment and transport apparatus and a work appearance inspection apparatus configured to be able to transport a work at a much higher speed than before and to inspect the appearance. There is.

The workpiece aligning and conveying apparatus of the present invention is an appearance inspection apparatus for a workpiece, which is an electronic component having a polyhedron shape such as a semiconductor element, a crystal resonator, a crystal element, a chip capacitor, a resistor, a coil, and a terminal, and a polyhedron such as a cylindrical shape. A loading disk that rotates with an upward rotating shaft to move the loaded work to the delivery disk, and a delivery disk that rotates with an obliquely downward rotating shaft to deliver the moved work to the transfer surface , wherein in proximity to the outer periphery of the input disk transfer surface as the transfer path of the workpiece is formed are aligned for the rotating disk is disposed at the upward rotation shaft concentrically, the work is formed on the closing disc Rotating fee that is inserted into the inner peripheral surface of each of the recessed recesses that are formed, scraped up by the delivery disk, and delivered to the transfer surface. And a plurality of guide plates that divide the transfer surface into an inner peripheral side and an outer peripheral side are arranged close to the transfer surface of the alignment disk, and leading ends of the plurality of guide plates are provided. The transfer disks are arranged at different positions, and a plurality of the transfer disks are arranged at equal intervals around the upward rotating shaft, and the transfer is performed in different predetermined areas by the transfer disks. The workpieces transferred to the surface are independent in a plurality of rows corresponding one-to-one with the number of the delivery disks arranged by the guide plate from the front end entrance of the guide plate corresponding one- to -one to the different predetermined areas . It is characterized by being aligned and conveyed so as to pass through the workpiece transfer path.

  According to the present invention, the supply member for loading the workpiece, the loading disc rotating with the upward rotating shaft to move the loaded workpiece to the delivery disc, and the slant for delivering the moved workpiece to the transfer surface A transfer disk provided with a brush on the outer periphery rotating around a downward rotating shaft, and a guide plate that divides the transfer surface serving as a work transfer path into an inner peripheral side and an outer peripheral side are provided on the transfer surface of the alignment disk. And a plurality of the delivery disks are arranged at predetermined intervals around the upward rotation shaft, and the delivery disks provide separate transfer areas to the transfer surface. So that the workpieces that have been delivered become independent workpiece transfer paths in a plurality of rows that correspond one-to-one with the number of delivery disks arranged by the guide plate. Since each of the transfer disks is arranged and transported, the number of transfer disks is the number of independent work transfer paths in a plurality of rows, and the work transfer capacity is dramatically increased in proportion to the number of transfer disks. It becomes a structure which can convey a workpiece | work significantly at high speed compared with the past.

  In the present invention, a transfer surface serving as a workpiece transfer path is formed on the outer periphery of the loading disk, or a transfer surface serving as a workpiece transfer path is formed adjacent to the outer periphery of the loading disk so as to face upward. An alignment disk that rotates concentrically with the rotation axis is arranged. In the case where a transfer surface serving as a workpiece transfer path is formed on the outer periphery of the input disk, it is possible to eliminate a gap from the concave inner peripheral surface formed on the input disk to the transfer surface. It is possible to smoothly transfer a thin and small workpiece without being caught in the gap. Further, in the case of a configuration in which a transfer surface serving as a work transfer path is formed near the outer periphery of the input disk and an alignment disk that rotates concentrically with the upward rotation shaft is disposed, By rotating the disk in the same direction as the loading disk and setting the rotation speed of the alignment disk to a value larger than the rotation speed of the loading disk, smooth transfer can be performed while increasing the work conveying speed. .

  In the case where the alignment disk is arranged, the rotation speed of the alignment disk is preferably set to a rotation speed that is not less than 2 times and not more than 4 times the rotation speed of the loading disk. Is preferred. This is because as the outer peripheral speed increases, the workpiece to be conveyed follows the tangential direction, and the conveying posture becomes more stable. In addition, the rotation speed of the transfer disk and the upper limit of the rotation speed of the alignment disk are set independently so that the work is smoothly transferred from the transfer disk to the alignment disk.

The outer diameter of the main body of the delivery disk is set to a size that is half or less of the inner diameter of the recess that constitutes the concave inner peripheral surface of the input disk, and the workpiece that has been input to the recess is placed at the outer peripheral end of the recess. The work is placed on the flocking wire brush and the work placed on the flocking wire brush at the outer peripheral end by its own rotation is transferred to the transfer surface. Note that the wire brush on the outer periphery of the delivery disk may be eliminated, the outer circumference may be made of soft plastic or rubber, and the loaded work may be placed on the outer circumference end of the delivery disk.

  The present invention includes a linear feeder for supplying a workpiece from the transfer path to the next process, and the linear feeder takes over the workpiece transfer path and has a plurality of independent work transfer paths corresponding one-to-one. It is characterized by the fact that an alignment wall is arranged so as to be divided.

  According to the present invention, a plurality of rows are provided by attaching the linear feeder on which the alignment wall is arranged so as to be an independent workpiece conveyance path in a plurality of rows corresponding to the workpiece transfer path in a one-to-one correspondence. Thus, it is easy to smoothly feed the workpiece from the transfer path to the next process by aligning and conveying the workpiece independently. The linear feeder is provided with a transport disk that is rotated flush with the transfer surface by an upward rotating shaft, and the alignment wall is disposed close to the transport surface of the transport disk. By doing, it becomes easy to raise a workpiece conveyance speed and to supply to the following process.

  The workpiece visual inspection apparatus according to the present invention includes a feeder that aligns and conveys workpieces using the workpiece aligning and conveying device, and the workpieces that are aligned and conveyed by a plurality of rows and independent workpiece conveyance paths from the feeder are one-to-one. There is a one-to-one correspondence between a non-vibration relay stand having a conveyance groove that relays and conveys it through independent relay paths in a plurality of rows, and a work that is aligned and conveyed from the non-vibration relay stand in a plurality of rows and independent relay paths A first rotary indexer that receives and rotates and conveys in a plurality of rows that are independent in a first path; and a first path that is arranged below the first rotary indexer and that is independent in a plurality of rows from the first rotation indexer. A second rotary indexer that receives and rotates and conveys the workpieces that are aligned and conveyed through a plurality of independent second paths in a one-to-one correspondence, and imaging that is arranged at a plurality of locations for imaging the workpiece that is being conveyed A determination circuit for determining pass / fail of a workpiece being conveyed by an imaging signal sent from the imaging camera, a pass / fail screening unit disposed in proximity to the second indexer, and a plurality of pass / fail screening units provided in the pass / fail screening unit Ejecting means for ejecting the workpieces that have been judged pass / fail from the ejection port, and a control circuit for controlling them, and taking an image with the imaging camera while the workpieces are aligned and conveyed in multiple rows by the indexer.

The workpieces transferred to the transfer surface in the area are independent work pieces in a plurality of rows corresponding one-to-one with the number of the transfer disks arranged by the guide plate. Since it is configured to be divided into transfer paths and aligned and conveyed, the number of transfer disks is the number of independent work transfer paths in a plurality of rows, and is proportional to the number of transfer disks. It is possible to dramatically increase the workpiece transfer capability and to transfer the workpiece at a significantly higher speed than before. A plurality of rows corresponding to the number of the delivery discs on a one-to-one basis by arranging two or more and four or less delivery discs at regular intervals around the upward rotating shaft.

FIG. 4 is a cross-sectional view of the loading disk and the alignment disk of the workpiece alignment / conveyance apparatus according to the embodiment as viewed from the side. FIG. 5 is an enlarged cross-sectional view showing the transfer surface formed on the alignment disk.

  The workpiece aligning and conveying apparatus 1 according to the present embodiment has a shallow dish shape formed integrally with a hollow portion K1 that is recessed in a donut shape in the vicinity of the center, and is rotated in a horizontal shape with a feeding disk D1 that rotates horizontally. The loading disk D1 is held from below by the recess K2, and the alignment disk D2 that rotates horizontally independently of the loading disk D1 is provided (FIGS. 2 and 3). The input disk D1 is for moving the work 20 input to a predetermined position of the depression K1 to the alignment disk D2, and is upwardly connected and fixed on the center line P1-P1 line of the input disk D1. It rotates with the rotating shaft 171 (FIG. 3). The alignment disk D2 has a structure in which a transfer surface T2a serving as a transfer path for the workpiece 20 is formed in the vicinity of the outer periphery of the input disk D1 and rotates concentrically with the upward rotating shaft 171. A ring-shaped flange portion T2 is provided on the outer peripheral side of the alignment disk D2, and the outer peripheral side of the concave portion K2 is a flange portion T2 having a flat transfer surface T2a (FIG. 3). The height of the upper surface T2a of the flange portion T2 is set to a position slightly higher than the height of the loading disk D1, constitutes a flat portion, and serves as a transport surface for the workpiece 20 (FIG. 5).

  The upper end on the outer peripheral side of the loading disk D1 and the flange T2 have a slight gap S9 to the extent that the workpiece 20 does not fall, and rotate horizontally in the same rotational direction without contact with each other (see FIG. 5). The example shown in FIG. 2 is configured to rotate counterclockwise (reference ccw) when viewed from above, but the rotation direction can be arbitrarily set. More specifically, the size of the gap S9 is set to a value smaller than the height (or outer diameter) 20H of the workpiece 20, and the input disk D1 and the alignment disk D2 can rotate horizontally without contact with each other. Set to a size within the range.

  The rotation shaft 171 connected and fixed on the center line P1-P1 line of the input disk D1 disposed on the inner side rotates through a bearing disposed on a base 151 integrally fixed to the upper side of the housing plate E4. It freely couples through the center of the base 151 and is coupled to the drive shaft of the drive means (drive motor) M1 attached and supported on the lower side of the housing plate E4 (FIGS. 3 and 4).

And a pulley (small pulley) coupled and fixed above the drive shaft of the drive means (drive motor) M2 attached and supported on the lower side of the housing plate E4 is belt-connected by a belt 152 (see FIG. 3, FIG. 4). By this belt connection, it becomes easy to rotate the outer alignment disk D2 concentrically and horizontally even with the drive motor M2 having a small driving force.

  Reference numeral 50 denotes a supply member (hopper) that supplies the workpiece 20 to the donut-shaped depression K1. The hopper 50 includes, for example, a cylindrical container in which a spiral workpiece conveyance groove is formed on an inner peripheral side surface thereof, a drive motor connected to a roller that rotates in contact with the outer peripheral side surface of the cylindrical container, and the cylindrical container From a semi-cylindrical cradle for receiving the outer peripheral side surface, and a slide facing obliquely downward at a predetermined angle in order to slide the work 20 taken out from the opening of the cylindrical container toward the donut-shaped depression K1. The workpiece supply amount is limited so that the workpiece 20 does not jump out a large amount at a time. As a method for supplying the workpiece 20 to the indented portion K1, in addition to the above method, a method of supplying a bulk-packing container from a slide while slightly vibrating, a method of directly placing a predetermined amount of workpieces in a batch type, and a small parts feeder And a continuous supply method.

  Reference numeral F1 (F2) is a transfer disk for transferring the workpiece 20 that has been inserted into the depression K1 and moved by the rotation of the input disk D1 to the transfer surface T2a of the alignment disk D2 (FIGS. 1 to FIG. 1). 3). The input disk D1 rotates horizontally with the upward rotating shaft 171, while the delivery disk F1 rotates with the obliquely downward rotating shaft 175. Similarly, the delivery disk F2 has the obliquely downwardly oriented rotational axis. Rotate at 176 (FIG. 1). The delivery disk F1 is connected to the motor M31, and the delivery disk F2 is connected to the motor M32. The rotation speed of the motor M31 is substantially the same as the rotation speed of the motor M32. The transfer disk F1 (F2) has a work scraping wire implanted in an outward brush shape along its outer periphery, and is in sliding contact with the inner peripheral side surface from the bottom of the donut-shaped recess K1. It is arranged diagonally (FIG. 3). That is, the outer peripheral end of the delivery disk F1 (F2) (which is flocked in this embodiment) is formed on the inner peripheral side surface formed as a gentle curvature from the bottom of the depression K1 of the input disk D1 to the upper surface T1a on the outer peripheral side. While the wire brush) is in sliding contact, the workpiece 20 is gradually scraped from the bottom along the concave inner peripheral side surface, and delivered to the upper surface T2a on the outer peripheral side of the alignment disk D2. In the example shown in FIG. 2, the delivery disk F1 (F2) is configured to rotate at a counterclockwise reference C1 (C2) as viewed from above, but the rotation direction and the insertion direction of the delivery disk F1 (F2). The rotation direction of the disk D1 may be the same as viewed from above, and the rotation direction may be clockwise.

  The outer diameter of the main body of the delivery disk F1 (F2) is set to be ½ or less of the inner diameter of the recess K1 of the loading disk D1 and ¼ or more (FIGS. 2 and 3). This is because the outer peripheral end of the transfer disk F1 (F2) is slidably contacted along the concave inner peripheral side surface of the recess K1 while leaving a gap between the transfer disks F1 and F2. In the present embodiment, the delivery disk F1 (F2) has a hair brush planted on the outer periphery thereof, and the hair transplantation wire brush on the outer periphery of the delivery disk F1 (F2) placed in the recess K1. The workpiece 20 placed on the flocking wire brush is moved on the transfer surface T2a of the alignment disk D2 by being rotated. Note that the wire brush on the outer periphery of the transfer disk F1 (F2) is eliminated, the outer periphery thereof is made of soft plastic or rubber, and the loaded work 20 is placed on the outer peripheral end of the transfer disk F1 (F2). good.

  In the present embodiment, two delivery disks F1 and F2 are arranged around the upward rotation shaft 171 of the input disk D1 in a rotationally symmetrical manner at equal intervals of 180 degrees (FIGS. 1 and 3). That is, there is an oblique center line Q1-Q1 of the delivery disk F1 around the vertical center line P1-P1 of the loading disk D1, and the oblique center line of the delivery disk F2 is positioned 180 degrees rotationally symmetric. There is Q2-Q2 (FIG. 1). The angle formed by the vertical center line P1-P1 and the oblique center line Q1-Q1 (oblique center line Q2-Q2) is set within a range of 5 to 50 degrees according to the shape of the recess K1. The

  The alignment disk D2 rotates in the same direction as the loading disk D1, and the rotation speed of the alignment disk D2 is set to a value larger than the rotation speed of the loading disk D1. Preferably, the rotation speed of the alignment disk D2 is set to a rotation speed that is at least twice and at most four times the rotation speed of the loading disk D1. This is because as the outer peripheral speed increases, the workpiece 20 to be conveyed follows the tangential direction and the conveying posture thereof becomes more stable. In addition, the upper limit value of the rotation speed of the alignment disk D2 is set so that the work 20 can be smoothly transferred from the transfer disk F1 to the alignment disk D2.
