JP 2002-326059 A

  Patent Document 1 prevents a situation in which a workpiece is dropped (jumped out) or clogged when a workpiece is supplied (stored) in a conveyance groove of a rotating disk. In particular, a linear feeder has a V-shaped groove. A guide plate is provided on the outer side of the rotating disk, a guide plate is provided from the guide plate so as to extend in and out parallel to the V-shaped valley in the pocket of the rotating disk, or a fixed table. A guide nozzle is further provided, and a conveyor is provided between the front end of the linear feeder and the rotating disk and fixed table.

  However, none of them are sufficient for preventing dropouts or clogging. For example, in a case where one side of the V-groove linear feeder is cut off, the rotary disk rotates, but the linear feeder does not move. One side is cut away. However, if such a notch is formed, the workpiece may fall off from the notch. In addition, a work may be sandwiched between a rotating disk that is rotationally driven and one side of the linear feeder that does not move and is not cut, and the rotating disk may rotate before the work posture is determined, and the work may jump out. Furthermore, in Patent Document 1, suction and exhaust are switched by a valve in a conveyance groove (pocket) of a rotating disk by a valve and an intake / exhaust port connected to an intake / exhaust device is provided. Otherwise, the workpiece may fall off or become clogged.

  In addition, when the rotating disk is in a vertical arrangement, the rectilinear feeder is often arranged at a position below it (such as the 6 o'clock position of the watch), but depending on the apparatus, that position may not be preferable. In other words, if the space is limited due to securing a place to place the imaging means or the like or a tendency toward downsizing of the apparatus, it may not always be possible to place in the lower position.

  On the other hand, the workpiece inspection may be performed in a state where the workpiece is stored in the conveyance groove of the rotating disk. For example, when inspecting the electrical characteristics or the like of an IC chip such as an electronic element, there is a case in which a contactor that contacts the work is brought into contact with the outer periphery of a rotating disk so as to be sandwiched from both sides of the IC chip. However, in the conventional apparatus, there is a case where the workpiece is dropped during the contact.

  Accordingly, an object of the present invention is to reliably supply (store) the workpiece into the conveyance groove without dropping or clogging the workpiece, regardless of the position around the inspection rotary disc. An object of the present invention is to provide a workpiece inspection device in which a workpiece is not dropped even when an electrical inspection or the like is performed by contacting the workpiece in a stored state.

  A workpiece inspection apparatus according to a first aspect of the present invention includes an inspection rotating disk having a conveying groove formed on the outer periphery thereof, a supply means for supplying the workpiece to the conveying groove of the inspection rotating disk, and an inspection. A first guide disk disposed on the outer periphery of the rotating disk for inspection, wherein the first guide disk is formed with a guide groove covering the conveying groove of the inspection rotating disk on the outer periphery thereof. It rotates in the same direction as the disk in the circumferential direction. Here, in this specification, “the same direction in the circumferential direction” means that when the first guide disk rotates counterclockwise, the inspection rotating disk rotates clockwise, Say the opposite case.

  According to the present invention, when the work is supplied from the supply means, the guide groove of the first guide disk covers the conveyance groove of the inspection rotating disk, thereby preventing the work from falling off. Then, by rotating the guide disk in the same direction in the circumferential direction in accordance with the rotation of the inspection rotating disk, the situation where one side of the V-shaped groove comes into contact with the work as in the conventional case is prevented. After the work is stored in the conveyance groove, the guide groove of the first guide disk gradually moves away from the conveyance groove of the inspection rotating disk.

  According to a second aspect of the present invention, there is provided a workpiece inspection apparatus comprising: an inspection rotary disk having a conveying groove on the outer periphery thereof; and a second guide disk disposed on the outer periphery of the inspection rotary disk. A guide groove is formed on the outer periphery of the second guide disk to cover the conveying groove of the inspection rotating disk, and a contact for inspecting the workpiece is provided. The second guide disk is rotated for inspection. Rotating in the same direction as the disk in the circumferential direction, the contact is in contact with the work placed in the conveying groove.

  According to the present invention, when inspecting electrical characteristics or the like of a workpiece such as an IC chip, the second guide disk rotates in the same direction as the inspection rotating disk, and the contact is arranged in the conveying groove. Since the contact with the workpiece, the situation where the contact (probe) contacts with the workpiece as in the conventional case is prevented.

  According to a third aspect of the present invention, the conveyance groove of the inspection rotating disk and the guide groove of the first guide disk or the second guide disk are grooves formed in a direction perpendicular to the circumferential direction. In addition, the driving of the inspection rotating disk and the first guide disk or the second guide disk is a synchronous drive in which the conveyance groove and the guide groove are driven to face each other.

  According to the present invention, since the synchronous driving is performed so that the conveying groove and the guide groove face each other, the workpiece is not clogged or dropped off due to the shift of the movement of the grooves. In addition, since the first and second guide disks are made of rubber and covered with elasticity, the contact with the work is softened, preventing a situation where it jumps out and the work is damaged. To prevent such a situation.

  According to the workpiece inspection apparatus of the present invention, the first guide disk covers the workpiece supplied to the conveyance groove of the inspection rotary disk and rotates in the same direction in the circumferential direction. It is possible to prevent a situation where it is caused to clog or clog. In addition, the back gauge can be continuously sucked, thereby simplifying the suction operation and simplifying the control. On the other hand, the second guide disk rotates in the same direction as the inspection rotating disk in the circumferential direction when inspecting the electrical characteristics of a workpiece such as an IC chip, and the contact is arranged in the conveying groove. Since the contact with the workpiece, the situation where the contact comes off due to the contact of the contact with the workpiece can be prevented. According to the present invention, the first and second guide disks can be arranged at any position on the outer periphery of the inspection rotating disk. It becomes possible to eliminate the restriction of arrangement which must be arranged below.

The best mode for carrying out the present invention will be described below with reference to the drawings.
(First embodiment)
1 is a front view of a workpiece inspection apparatus according to the present embodiment, FIG. 2 is a sectional view of the workpiece inspection apparatus, and FIG. 3 is a sectional view of the workpiece inspection apparatus. FIG. 5 is a perspective view, and FIG. 5 is an enlarged front view of a workpiece conveyance state. The workpiece inspection apparatus 1 according to the present embodiment is a workpiece inspection apparatus that inspects a workpiece C such as a chip part such as an electronic element or an electronic circuit using an imaging unit. It includes second inspection rotating disks ID1, ID2, a linear feeder F as supply means for supplying the workpiece C, and a first guide disk G1 disposed on the outer periphery of the inspection rotating disk ID1. The work C to be inspected is a fine electronic element (micro object) C such as an IC chip or a chip capacitor (FIG. 9A), a tablet, a capsule tablet (capsule tablet) K, or the like ( FIG. 9B). In addition, although the workpiece | work C of this Embodiment is demonstrated as a rectangular parallelepiped-shaped workpiece | work, even if it is a cube shape, a thin plate-shaped chip component, etc., it is applicable.

  The rectilinear feeder F feeds the workpiece C taken out from a discharge port of a cylindrical feeder (not shown) into which the workpiece C is inserted while vibrating, and has a linear groove Fv continuous with the discharge port of the cylindrical feeder. The work C is supplied from the groove Fv to the conveying groove v1 of the first inspection rotary disk ID1. There may be a case where a non-vibration relay stand is disposed between the linear feeder F and the first inspection rotary disk ID1, and an imaging unit is disposed at this position.

  A back gauge ge is attached to a position facing the linear feeder F, and a first suction hole q1 is formed in the back gauge ge, and the workpiece C is sucked through the first suction hole q1 ( FIG. 5). The first suction hole q1 is formed toward the conveyance groove Fv of the rectilinear feeder F, and is provided with a connecting portion gep that is connected to a vacuum pump (not shown) as suction means. For this reason, when a suction force is applied by the vacuum pump, the workpiece C is moved from the conveyance groove Fv of the linear feeder F to the conveyance groove v1 of the inspection rotary disk ID1 described later and the guide groove G1v of the first guide disk G1. It can be guided by suction through the suction hole q1. That is, as shown in FIG. 5, by arranging the suction hole q1 of the back gauge ge at the contact point between both the disk ID1 and G1, the space formed by the groove v1 and the groove G1v of both the disk ID1, G1. Therefore, the suction operation can be performed easily and stably.

  The first and second rotating disks ID1 and ID2 are attached to the tip side of the shafts J1 and J2 attached to the base base B, and the motors M1 and M2 are attached to the other side of the shafts J1 and J2. (FIG. 2). The first and second rotating disks ID1 and ID2 rotate and convey a large number of workpieces C in the outer circumferential conveying grooves v1 and v2, and an outer peripheral roller S1b attached to the shafts J1 and J2 overlaps the suction ring S1a. Combined and configured. Conveying grooves v1 and v2 are formed in the outer peripheral roller S1b at a predetermined interval in a direction orthogonal to the tangential direction. The conveying grooves v1 and v2 are formed in a V shape corresponding to the conveying groove Fv of the linear feeder F, and a second suction is applied to the bottom (v-shaped tip) of the V-shaped conveying grooves v1 and v2. A hole q2 is formed, and the second suction hole q2 is connected to the suction slit Ss of the suction ring S1a and is connected to a vacuum pump (not shown) as suction means via the connector Q. (Fig. 2). Therefore, even if the rotary disks ID1 and ID2 rotate, the workpiece C does not fall out of the conveying grooves v1 and v2. Further, the suction ring S1a is connected to a second suction hole q2 for sucking from the linear feeder F to the V-shaped transport groove v1 (FIGS. 2, 3, and 5). The second suction hole q2 enables rotational conveyance with the conveyance groove v1 stored. After the workpiece C is sucked, the second suction hole q2 continues to be sucked to maintain the rotational conveyance state.

  The V-shaped transport groove v1 is formed symmetrically with the guide groove G1v of the first guide disk G1 facing each other, the transport groove is V-shaped, and the other guide groove G1v is matched to the same V. It is formed in a letter shape. As shown in FIG. 9A, the conveyance groove v1 and the guide groove G1v of the first guide disk G1 cover the four side surfaces (the first surface to the fourth surface) of the rectangular parallelepiped workpiece C. One side of the remaining workpiece C becomes the feed side surface (fifth surface) from the linear feeder F ((arrow in FIG. 9A)), and the other remaining surface (sixth surface) is the back. The surface of the gauge ge on the first suction hole q1 side is covered with the surface excluding the fifth surface of the workpiece C.

  The suction slit Ss of the suction ring S1a of the first inspection rotating disk ID1 is provided at a position approximately from the 9 o'clock direction to the 5 o'clock range of the clockwise rotation, and the suction ring of the second rotating disk ID2 The suction slit Ss of S1a is provided on the half circumference from the 10 o'clock position of the timepiece to the 5 o'clock position of the left rotation, and extends to the position where the air passages A1,. The workpiece C, which is an electronic element, is positioned from the 5 o'clock position of the first inspection rotary disk ID1 at a position deviating from the position of the suction slit Ss having the predetermined length to the 10 o'clock position of the second rotary disk ID2. Is transferred to the conveyance groove v2, and is conveyed counterclockwise from the 6 o'clock position to the 5 o'clock position.

  The first inspection rotary disk ID1 and the second rotary disk ID2 are rotated by a continuous rotation method using a vertical arrangement. The second rotating disk ID2 is arranged at an oblique position on the lower side of the first inspection rotating disk ID1. The first inspection rotary disk ID1 is rotated in the same direction as the rotation direction of the timepiece by a rotation axis J1 arranged at the center thereof. The second rotating disk ID2 rotates in the direction opposite to the rotating direction of the timepiece by the rotation axis J2 arranged at the center thereof. Drive axes (motors) M1 and M2 are attached to the shafts J1 and J2 of the first and second rotating disks ID1 and ID2, respectively, and rotate. However, they are configured to be driven synchronously via gears E1 and E2. (Fig. 2). The first and second rotating disks ID1 and ID2 are driven synchronously by intermittent driving with the first guide disk G1, but may be continuously driven.

  The first guide disk G1 is disposed on the outer periphery of the inspection rotary disk ID1, and has a role as a guide groove G1v covering the conveyance groove v1 of the inspection rotary disk ID1 on the outer periphery. As shown in FIG. 2, the first guide disk G1 has a shaft J3 attached to the base base B and is attached to the tip side of the shaft J3, and on the other side, the first inspection rotary disk ID1. The motor M1 and the gears E1 and E3 are connected (FIG. 2). That is, motors (stepping motors) M1 and M2 as rotation driving means are respectively attached to the axes J1 and J2 of the first inspection rotary disk ID1 and the second rotary disk ID2, and the first guide disk G1. This rotational drive is coupled to the shaft J1 of the first inspection rotary disk ID1 via gears (non-backlash gears) E1 and E3, and is driven synchronously with the rotation of the first inspection rotary disk ID1. This synchronous driving is intermittent driving. Therefore, the driving of the first inspection rotating disk ID1 and the first guide disk G1 is synchronous driving in which the guide groove G1v facing the conveyance groove v1 faces. By using the same power source, it is not necessary to receive the drive source of the first guide disk G1 separately.

  The guide groove G1v of the first guide disk G1 is formed so as to correspond to the conveyance groove v1 of the inspection rotary disks ID1, ID2. Since the workpiece of the present embodiment has a rectangular parallelepiped shape, one conveying groove v1 is formed in a V shape, and the other guide groove G1v is formed in the same V shape in accordance with this, and is symmetrical. For example, when the workpiece C is a tablet capsule, a conveyance groove vK having a U-shaped cross section may be formed (FIG. 9B). In this case, one conveyance groove vK and the other guide groove G1v are Symmetry is preferred.

  Here, the first guide disk G1 is arranged at the 9 o'clock position with a watch hand with respect to the inspection rotary disk ID1, but since both are of the same disk shape, the first guide The disk G1 is the same regardless of the position on the outer periphery of the inspection rotary disk ID1. That is, the inspection rotary disk ID1 is covered through the workpiece C in the conveyance groove v1 of the inspection rotary disk ID1 at the 6 o'clock position or any other position. The diameter of the first guide disk G1 is preferably as small as possible. This is because the apparatus can be miniaturized by using a small diameter, and in this embodiment, the rotational drive of the first guide disk G1 is changed to the drive source (stepping motor) of the axis of the inspection rotary disk ID1. This is because the load applied to the drive source of the inspection rotary disk ID1 can be reduced as much as possible. Although the first guide disk G1 of the present embodiment is described as being made of stainless steel, it can also be made of rubber as in the second embodiment.

  Imaging means S1... S6 for imaging the outer periphery of the workpiece (electronic element) C1 are imaging means S1 and S2 for imaging at the 12 o'clock position in the middle of conveyance by the first inspection rotary disk ID1, and the position at about 2 o'clock thereafter The image pickup means S3 and S4 for picking up an image of the workpiece C in the middle of the transfer and the image pickup means S5 and S6 for picking up the image of the second rotary disk ID2 in the middle of the transfer are arranged. Each imaging means S1... S6 is an image sensor, an optical outer diameter measuring device combining an image sensor and a light emitting diode, a high-sensitivity camera (C1C1D camera), and the like, and images the outer periphery of a rectangular parallelepiped workpiece C. To do. As a result, the control unit (not shown) images the length / width and area and inspects for the presence or absence of scratches.

  The image pickup means S1 and S2 pick up images of the third surface C3 and the fourth surface C4 of the workpiece C from an oblique direction in a state of being accommodated in the conveyance groove v1 of the first inspection rotary disk ID1, and the image pickup means S3 S4 images the fifth surface C5 and the sixth surface C6 from the front and rear (front and rear in the drawing), and the imaging means S5 and S6 are stored in the conveying groove v2 of the second rotating disk ID2. The first surface C1 and the second surface C2 of C are imaged from an oblique direction, and a camera mounted on each tip is disposed toward the workpiece C.

  The present embodiment includes imaging means S1... S6 for photographing the workpiece C in the conveyance process by the first and second rotating disks ID1 and ID2, and images and inspects the workpiece C from six directions. It is also possible to take images from four directions or from two directions. It is also possible to add an imaging means for imaging on a vibration-free relay stand. In the present embodiment, the image pickup means S1 and S2 (or the image pickup means S3 and S4) simultaneously photograph the workpiece C at the same position. However, the image pickup means S1 and S2 can also photograph at different positions. It is.

  Blower passages A1... A4 for taking out the workpiece C are provided on the lower side of the second rotary disk ID2, and these blower passages A1... A4 are connected to blower means (not shown). A discharge-side bracket B1 is attached to the outer peripheral position of the second rotary disk ID2 from the 5 o'clock position to the 6 o'clock position, and the discharge-side bracket B1 is taken out from the conveying groove v2 and is selected (not shown). A plurality of outlets Bb connected to each other, and an optical sensor for detecting the discharge and counting the number is attached. That is, on the discharge side, air stronger than the suction through the suction means of the suction slit Ss is blown and taken out from the transport groove v2. In the present embodiment, selection of non-defective products, re-inspected products, and non-inspectable products, and all of them are finally discharged.

  Next, the operation in the case of inspecting the electronic element (workpiece) C1 by actually using the workpiece inspection apparatus 1 of the present embodiment will be described.

  When the workpiece C conveyed to the conveying groove Fv of the linear feeder F reaches the tip of the linear feeder F, the workpiece C is sucked by the first suction hole q1 of the back gauge ge facing the position of the linear feeder F, and the conveying groove It is stored in v1 and the guide groove G1v. In other words, one workpiece C is arranged in a space formed by the conveying groove v1 and the guide groove G1v. The suction by the first suction hole q1 is stopped when sucked and switched to this time, and this time, the suction is performed by the second suction hole q1 connected to the transport groove v1 of the inspection rotary disk ID1, and the workpiece is transferred to the transport groove v1. The first surface C1 and the second surface C2 of C are adsorbed. Therefore, the work C circulates in the circulation direction of the first inspection rotary disk ID1 without dropping from the conveyance groove v1. The first guide disk G1 rotates simultaneously in the same direction in the circumferential direction by synchronous driving with the first inspection rotary disk ID1 (the first guide disk G1 rotates counterclockwise, No. 1 rotating disk ID1 rotates clockwise), as in the conventional case, one of them is driven and the other is not driven, but the work C is bitten and it still rotates and jumps out (bounces). The posture of the workpiece C is adjusted by the conveying groove v1 and the guide groove G1v. That is, when the workpiece C is stored in the conveying groove v1, the first guide disk G1 rotates in the same direction in the circumferential direction and continues to cover the workpiece C until it is arranged in the conveying groove v1. Thereafter, the guide groove G1v of the first guide disk G1 is gradually separated from the conveyance groove v1 of the inspection rotary disk ID1.

  When the guide groove G1v of the first guide disk G1 is separated from the conveyance groove v1 of the inspection rotary disk ID1, the third surface C3 and the fourth surface C4 of the workpiece C are rotated for inspection in a state of protruding from the conveyance groove v1. When the outer periphery of the disk ID1 is conveyed and conveyed to the 12 o'clock position of the timepiece, the work C has two rectangular parallelepiped shapes (third surface C3 and fourth surface C4) in two directions by the imaging means S1 and S2. Is taken from. Thereafter, the fifth surface C5 and the sixth surface C6 of the workpiece C are imaged by the imaging means S3, S4. The first inspection rotating disk ID1 is deviated from the position of the suction slit Ss of the predetermined length of the first inspection rotating disk ID1 at the position of about 5 o'clock of the first inspection rotating disk ID1, while the second rotating disk ID2 is conveyed. Passed to the groove v2. When the workpiece C is conveyed by the rotation of the second rotary disk ID2, the workpiece C is imaged by the imaging means S5 and S6 at the 8 o'clock position of the timepiece. In this way, the workpiece C is rotated and conveyed so as to draw an oblique S-shaped curve. The imaging result is collated with the accumulated data by the control unit, and selection is made as to whether it is a non-defective product, a defective product, a re-inspected product, or a non-inspectable product. When the imaging by the imaging means S1... S4 is completed and the above sorting is performed and the paper is rotated and conveyed to the discharge side at the 6 o'clock to 8 o'clock position, on the discharge side, the suction is performed on the discharge side. The feeding work C is separated from the conveying groove v2 through the air supply hole for supplying stronger air, and is stored in the sorting box (not shown) through the discharge port Bb.

(Second Embodiment)
FIG. 7 is a front view of the second embodiment, and FIG. 8 is a plan view showing a state of contact inspection using the contacts Gp1 and Gp2. This embodiment is used when inspecting the electrical characteristics and the like of a workpiece C such as an IC chip, and a second guide disk G2 is arranged on the outer periphery of the inspection rotary disk ID1. The second guide disk G2 has substantially the same structure as the first guide disk G1 of the first embodiment, and a guide groove G2v that covers the conveyance groove v1 of the inspection rotary disk ID1 is formed. Then, it rotates in the same direction as the inspection rotating disk ID1 in the circumferential direction. In the present embodiment, the contacts Gp1 and Gp2 are in contact with the fifth surface C5 and the sixth surface C6 of the workpiece C (FIG. 9A). The contacts Gp1 and Gp2 are used for inspecting the electrical characteristics of the work C when the IC chip is an IC chip, or inspecting the electric capacity of a chip-type capacitor, and are selectively used according to the type of inspection. The second guide disk G2 is arranged at two locations on the outer periphery of the inspection rotating disk ID1, and can cope with different inspections. The contactors Gp1 and Gp2 are a pair of left and right, and are formed in a U-shape so as to contact the fifth surface C5 and the sixth surface C6 of the workpiece C with elasticity. The contacts Gp1 and Gp2 may be probes (inspection needles). Although not shown, the contact Gp is connected to an inspection unit of the main body, and inspection data such as electrical characteristics is sent and the inspection information is recorded. The number of such second guide disks G2 may be arranged on the outer periphery of the inspection rotary disks ID1 and ID2, and can be arranged at any position.

  The second guide disk G2 of the present embodiment is made of rubber. In addition, it is preferable to use rubber even at least in the guide groove G2v. This is because the guide groove G2v covers the conveyance groove v1 of the inspection rotary disk ID1, and therefore it is preferable that the guide groove G2v comes into contact with the workpiece C as gently as possible.

  Therefore, when the workpiece C stored in the conveyance groove of the inspection rotary disk ID1 is conveyed to the 12 o'clock position of the timepiece, for example, via the first guide disk G1, the second guide disk G2 covers the conveying groove v1, and the contacts Gp1 and Gp2 come into contact with the workpiece C arranged in the conveying groove v1. That is, the guide groove G2v of the rubber second guide disk G2 is covered by the elastic force of the work groove C1 of the conveyance groove v1 of the inspection rotary disk ID1, and the contacts Gp1 and Gp2 are conveyed. By sandwiching and contacting the fifth surface C5 and the sixth surface C6 of the workpiece C arranged in the groove v1 from the left and right (FIG. 8), the electrical characteristics and the like of the electronic element that is the workpiece C are detected. Therefore, the inspection is performed without dropping from the conveyance groove v1 of the inspection rotary disk ID1 during this detection.

  As described above, the present embodiment has been described in the case where the present invention is applied to the vertically arranged inspection rotating disks ID1 and ID2, but the present invention can also be applied to a horizontally disposed inspection rotating disk. I will not. In this embodiment, the suction holes q1 and q2 are provided. However, in the present invention, the first guide disk G1 and the second guide disk G2 are the inspection rotary disks ID1 and ID2.
