For example, when the object to be conveyed has a substantially rectangular parallelepiped shape and the object to be conveyed before being rotated by the suction moving unit is conveyed in the major axis direction, the object to be conveyed is conveyed in the minor axis direction. It will be. As a result, since the length of the conveyed object along the circumferential direction of the disk-shaped part can be shortened, many objects to be conveyed with appropriate intervals can be arranged on the disk-shaped part.

  According to the seventh aspect of the present invention, the object to be transported supplied to the disk-shaped portion is positioned radially outside the disk-shaped portion by one suction moving portion among the plurality of suction moving portions. It is rotated. Thereby, the conveyed object supplied to the disk-shaped part can be reliably separated one by one.

With this electronic component supply guide 14, electronic components M of an electronic component supply feeder (not shown) are continuously supplied to the upper surface of the disk-shaped member 20 in a state of being aligned in a line.

  In addition, a suction roller 26 is disposed above the disk-shaped member 20 and on the transport locus of the electronic component M supplied by the electronic component supply guide 14. The suction roller 26 is a cylindrical roller member that is centered on the transport locus of the electronic component M or radially inward of the transport track and has suction holes formed on the entire outer surface or a partial region. A main body 26A and a second rotating shaft 26B that is located on the transport locus of the electronic component M or on the radially inner side of the transport locus, is connected to the upper surface of the roller member body 26A, and rotates the roller member body 26A. , Is composed of. Further, the suction roller 26 is supported by a support member (not shown) or the like so that the roller member body 26A is separated from the upper surface of the disk-shaped member 20 by a predetermined distance. The roller member main body 26A is set to a size such that the electronic component M to be conveyed contacts.

  Here, an endless belt 28 is stretched between the second rotating shaft 26B and the first rotating shaft 22, and the diameter of the second rotating shaft 26B is set smaller than the diameter of the first rotating shaft 22. Yes. Thereby, when the first rotating shaft 22 is rotated, the second rotating shaft 26B is rotated in the same direction by the endless belt 28, and the rotating speed of the second rotating shaft 26B is faster than the rotating speed of the first rotating shaft 22. Become.

  The second rotating shaft 26B and the first rotating shaft 22 are not configured to be connected by the endless belt 28, but an independent drive motor (not shown) is provided separately, and the second rotating shaft 26B is connected to the first rotating shaft by this drive motor. You may comprise so that it may rotate at a rotational speed faster than the rotational speed of 22.

  Further, a suction pump (not shown) is connected to the suction roller 26, and air is sucked from the suction hole of the roller member body 26A by the operation of the suction pump.

  The imaging unit 16 includes a CCD camera that images the appearance of the electronic component M, and an illumination lamp that irradiates light to the electronic component M that is an imaging target.

  The quality determination unit 18 includes an image processing device, and determines quality of the appearance of the electronic component M based on the image data captured by the imaging unit 16.

  Further, in the vicinity of the disk-shaped member 20, a discharge portion (not shown) for discharging the electronic component M whose appearance is inspected from the disk-shaped member 20 is disposed. The discharge unit is composed of, for example, a plurality of compressed air nozzles that discharge compressed air to the electronic component M from the disk-like member 20, and an air valve (not shown) based on the determination result of the pass / fail determination unit 18. It is designed to be controlled via. In addition, each collection box (not shown) for collecting the discharged electronic component M is arranged at a position corresponding to each compressed air nozzle.

  Next, operations of the separation / conveyance device 12 and the appearance inspection device 10 according to the present embodiment will be described.

  As shown in FIG. 1, when the first rotating shaft 22 is rotated by driving the drive motor, the disk-shaped member 20 is rotated around the first rotating shaft 22. When the first rotating shaft 22 is rotated, the rotational driving force of the first rotating shaft 22 is transmitted to the second rotating shaft 22B by the endless belt 28, and the suction roller 26 rotates in the same direction as the disk-shaped member 20.

  A plurality of electronic components M are supplied to the upper surface of the rotating disk-shaped member 20 in an aligned manner by the electronic component supply guide 14. The plurality of electronic components M supplied to the upper surface of the disk-shaped member 20 are conveyed in the circumferential direction along with the rotation of the disk-shaped member 20 while maintaining the state of being aligned in a row by the alignment guide 24.

  As the electronic component M is conveyed, the electronic component M eventually comes into contact with the outer peripheral surface of the roller member body 26A of the suction roller 26. When the electronic component M comes into contact with the outer peripheral surface of the roller member main body 26A, the suction pump operates and air is sucked from the suction holes. Thereby, the electronic component M is adsorbed on the outer peripheral surface of the roller member main body 26A. Then, in a state where the electronic component M is attracted to the outer peripheral surface of the roller member main body 26A, the electronic component M is rotated by about 90 degrees together with the roller member main body 26A, and the electronic before being attracted to the outer peripheral surface of the roller member main body 26A. The electronic component M is rotationally moved to a position radially outward from the conveyance trajectory of the component M.

  When the electronic component M is rotated and moved outward in the radial direction of the disk-like member 20 by the roller member main body 26A, the operation of the suction pump is stopped. As a result, the suction force from the roller member main body 26A is released, so that the electronic component M is separated from the outer peripheral surface of the roller member main body 26A and is conveyed again in the circumferential direction along with the rotation of the disk-shaped member 20. When one electronic component M is rotated, the subsequent electronic component M is attracted to the roller member body 26A and rotated. This process is repeated, and all the electronic components M supplied to the upper surface of the disk-shaped member 20 by the electronic component supply guide 14 are moved radially outward.

  Here, since the diameter of the second rotating shaft 26B is set smaller than the diameter of the first rotating shaft 22, the rotating speed of the second rotating shaft 26B becomes faster than the rotating speed of the first rotating shaft 22. Thereby, the rotation speed of the roller member main body 26 </ b> A of the suction roller 26 becomes faster than the rotation speed of the disk-shaped member 20. As a result, the interval between the electronic components M that have been rotationally moved radially outward of the disk-shaped member 20 is greatly increased, and the electronic component M supplied to the upper surface of the disk-shaped member 20 by the electronic component supply guide 14 is One by one is reliably separated.

  As described above, when the electronic components M separated one by one are conveyed in the circumferential direction along with the rotation of the disk-shaped member 20, the electronic components M reach the imaging unit 16. When the electronic component M reaches the imaging unit 16, the illumination lamp irradiates light and the CCD camera captures the appearance. The image data captured by the CCD camera is transmitted to the quality determination unit, and the quality of the appearance of the electronic component M is determined. Thereby, the quality / defectiveness of the electronic component M can be classified.

  When the electronic component M passes through the imaging unit 16, it eventually reaches the discharge unit. In the discharge unit, a plurality of compressed air nozzles are controlled via an air valve based on the inspection result of the imaging unit 16, and compressed air is blown from the predetermined compressed air nozzle to the electronic component M. When compressed air is blown onto the electronic component M, the electronic component M is discharged radially outward from the upper surface of the disk-shaped member 20 and is collected in a predetermined collection box. Thereby, it can collect | recover in the state which distinguished the quality and defect of the electronic component M.

  As described above, according to the separating and conveying apparatus of the present embodiment, the electronic components M can be reliably separated one by one with a simple configuration mainly using the disk-like member 20 and the suction roller 26. it can. In addition, the orientation of the conveyed electronic component M with respect to the conveyance direction can be arbitrarily changed with a simple configuration mainly using only the disk-shaped member 20 and the suction roller 26.

  In addition, since the electronic components M are supplied to the disk-shaped member 20 by the electronic component supply guide 14 in a state in which the electronic components M are aligned in a line, the disk-shaped member 20 is simply provided by the suction roller 26 only at one location. All of the electronic components M supplied to can be reliably separated one by one. Thereby, the separation conveyance apparatus 12 can be made into a simple structure, and the manufacturing cost can also be reduced.

  Further, the electronic component M is rotationally moved by the suction roller 26 to the radially outer position of the disk-shaped member 20, so that the transportation speed of the electronic component M moved to the radially outer position of the disk-shaped member 20 is increased. Therefore, the electronic component M can be arranged on the disk-like member 20 with a predetermined interval (appropriate interval). In addition, by rotating the electronic component M to the radially outer position of the disk-shaped member 20, the appearance of the electronic component M can be easily captured by the imaging unit 16 disposed radially outward.

  Next, a separation transport device and an appearance inspection device according to a second embodiment of the present invention will be described. The separation / conveyance device of this embodiment separates and conveys a substantially rectangular parallelepiped electronic component, and the appearance inspection device of this embodiment inspects the appearance of all side surfaces (six surfaces) of the electronic component. In addition, the same code | symbol is attached | subjected to the structure similar to the separation conveying apparatus and appearance inspection apparatus which concern on 1st Embodiment, and the description including an effect | action and an effect is abbreviate | omitted suitably.

  As shown in FIG. 2, the separation conveyance device and the appearance inspection device of the present embodiment are arranged above the disk-shaped member 20 in a region between the electronic component supply guide 14 and the suction roller 26 and are disk-shaped members. The first imaging unit 16A that images the upper surface M1 of the electronic component M supplied to 20 and the lower surface (the surface that contacts the disk-shaped member 20) M2 that is disposed below the disk-shaped member 20 are imaged. The second imaging unit 16B, the third imaging unit 16C that images the left side surface M3 of the electronic component M that is disposed on the outer side in the radial direction of the disk-shaped member 20, and is supplied to the disk-shaped member 20, and the disk-shaped member And a fourth imaging unit 16D that images the right side surface M4 of the electronic component M and is arranged on the inner side of the radial direction.

  In addition, the separation conveyance device and the appearance inspection device of the present embodiment are arranged on the downstream side in the electronic component conveyance direction with respect to the suction roller 26 and radially outside the disk-like member 20, and are rotated by about 90 degrees by the suction roller 26. A fifth imaging unit 16E that images the rear surface M5 of the moved electronic component M, and a sixth imaging unit 16F that is disposed inside the disk-shaped member 20 in the radial direction and images the front surface M6 of the electronic component M. ing. In addition, the structural member of each imaging part 16A, 16B, 16C, 16D, 16E, 16F is the same as the structural member of the imaging part 16 of 1st Embodiment.

  According to the present embodiment, when the electronic component M is supplied to the disk-shaped member 20 by the electronic component supply guide 14, the electronic component M is conveyed in the circumferential direction along with the rotation of the disk-shaped member 20, The first imaging unit 16A images the upper surface M1 of the electronic component M, and the second imaging unit 16B images the lower surface M2. Here, since the disk-shaped member 20 is made of a colorless and transparent material (for example, glass), even when the second imaging unit 16B is disposed below the disk-shaped member 20, the second imaging unit 16B. Thus, the lower surface M2 of the electronic component M can be imaged through the disk-shaped member 20. Thereby, the lower surface M2 can be easily imaged without changing the orientation of the lower surface M2 of the electronic component M. As the electronic component M is further conveyed, the third imaging unit 16C images the left side surface M3 of the electronic component M, and the fourth imaging unit 16D images the right side surface M4.

  When the electronic component M is rotated and moved by approximately 90 degrees by the suction roller 26 and conveyed in the circumferential direction along with the rotation of the disk-shaped member 20, the rear surface M5 of the electronic component M is imaged by the fifth imaging unit 16E. The front surface M6 of the electronic component M is imaged by the sixth imaging unit 16F.

  As described above, according to the present embodiment, the front surface M6 of the substantially rectangular parallelepiped electronic component M is attracted to the suction roller 26 and is rotated approximately 90 degrees, so that the electronic component can be used without using a complicated mechanism. All the side surfaces M1, M2, M3, M4, M5, and M6 of M can be easily imaged by the imaging units 16A, 16B, 16C, 16D, 16E, and 16F.

  In particular, since the electronic component M is rotated approximately 90 degrees by the suction roller 26, the direction (direction) of the front surface M6 (rear surface M5) of the electronic component M that contacts the suction roller 26 is changed by approximately 90 degrees. Thereby, when the electronic component before being rotationally moved by the suction roller 26 is conveyed in the major axis direction, the electronic component M is conveyed in the minor axis direction. As a result, since the length of the electronic component M along the circumferential direction of the disk-shaped member 20 can be shortened, many electronic components M with appropriate intervals can be arranged on the disk-shaped member 20. .

  Further, since the electronic component M is rotated approximately 90 degrees by the suction roller 26, the side surfaces M3, M5 of the electronic component M can be obtained simply by installing the imaging units 16B, 16C, 16E on the radially outer side of the disk-shaped member 20. Can be imaged. Thus, each imaging part 16B, 16C, and 16E can be installed in the place where it is easy to install, and the side surfaces M3 and M5 of the electronic component M can be easily imaged.

  In each of the above embodiments, the configuration in which one suction roller 26 is provided has been described as an example. However, the configuration is not limited to this configuration, and a configuration in which a plurality of suction rollers are provided may be used. For example, by providing two suction rollers at different positions in the radial direction of the disk-shaped member 20, the electronic component M supplied to the disk-shaped member 20 is rotated by a predetermined angle by the first suction roller. Then, the disk-shaped member 20 is rotationally moved to a position outside in the radial direction. Thereby, the electronic components M supplied to the disk-shaped member 20 can be reliably separated one by one. Subsequently, the electronic component M is further rotationally moved to a position on the radially outer side of the disk-like member 20 by the second suction roller. Thereby, the axial dimension of the conveyance direction of the electronic component M can be converted easily.
