The Further, each of the tip portions of the optical fibers 16a to 16d constitutes a sensor detection unit, with two of the four ends facing each other as a set. The sensor detection unit can detect the passage of the chip component 3 by capturing the change in the amount of transmitted light when the chip component 3 that has passed through the tube 19 passes through the opening 23.

  As shown in FIGS. 1 and 2, the inspection component passage portion 10 includes a horizontal shaft 31 stretched in the front-rear direction at the center of the frame 13, and a vertical shaft having an upper end connected to the horizontal shaft 31. 34, the sensor portion 14 is fixed to the lower end portion of the vertical shaft 34, and the tube 19 is disposed along the horizontal shaft 31. At this time, the lower surface of the fiber fixture 17 provided in the sensor unit 14 is opposed to the upper surface 20 of the distribution block 12 as shown in FIG. The horizontal shaft 31 is rotatably supported at both ends with respect to the frame 13 and one end is connected to the reversing motor 33 via a bearing 32. Therefore, as shown in FIG. When the reversing motor 33 is driven, the horizontal shaft 31 rotates in the forward and reverse directions, and the vertical shaft 34 swings accordingly, so that the sensor unit 14 performs a pendulum motion along the upper surface 20 of the sorting block 12.

  On the other hand, as shown in FIGS. 1, 2, and 5, the distribution block 12 is a quadrangular member having a curved upper surface 20, and is arranged in the vertical and horizontal directions on the upper surface 20. A large number of receiving holes 11 are provided. Each accommodation hole 11 penetrates to the lower surface side of the distribution block 12 and further communicates with a component accommodation portion (not shown) through a pipe 40.

The receiving port 48 and the sensor part 14 of the inspection component passing part 10 communicate with each other by a tube 19 piped along the horizontal shaft 31, and the chip component 3 blown into the receiving port 48 is placed inside the tube 19. Is then blown into the predetermined accommodation hole 11 from the opening 23 of the sensor unit 14, and the passage of the chip component 3 is detected at that time. The position of the receiving hole 11 in the sorting block 12 in which the chip component 3 is classified is based on the electrical characteristics of the chip component 3. Upon receiving the calculation processing by the computer, the distribution block 12 slides in the front-rear direction to determine the front-rear position, and at the same time, the sensor unit 14 moves in the left-right direction along the upper surface 20 of the distribution block 12 by the swing of the vertical shaft 34. The left and right positions are determined by moving to. In this way, the blowing position of the chip component 3 is determined, and the chip component 3 blown out from the opening 23 into the predetermined accommodation hole 11 is stored in the predetermined component accommodation portion through the pipe 40.

In the component sorting apparatus 50 according to this embodiment, when the inspected chip components are distributed from the test component passage unit 10 to the distribution block 12, the sorting block 12 remains fixed and the test component passage unit 10 is moved back and forth. The sensor unit 14 is aligned with a predetermined accommodation hole 11 by applying a sliding motion in the direction and a rotational motion in the left-right direction.

  Specifically, the tube 19 piped between the sensor part 14 of the inspection part passage part 10 and the chip blowing device 9 has a double structure, and the tube 19 is attached to be extendable. That is, the tube 19 is composed of an inner tube 19 a fixed to the guide block 58 of the frame 13 on the tip blowing device 9 side, and an outer tube 19 b attached to the slide block 51 and the horizontal shaft 31. In this structure, 31 bearing portions 61 are slidably supported on guide rails 52 fixed to the frame 13. Inside the slide block 51, the inner tube 19a and the outer tube 19b have a double structure, and when the slide block 51 slides, the outer tube 19b slides along the outer peripheral surface of the inner tube 19a to expand and contract. ing.

The slide block 51 is also connected to a cam mechanism 54 driven by an actuator 53, and slides in the front-rear direction with respect to the frame 13 by the function of the cam mechanism 54. The cam mechanism 54 is provided with a block body 56 provided with a long hole 55 and a guide pin 57 that moves in the long hole 55 in order to guide the movement of the slide block 51 in the front-rear direction.

  Therefore, the slide mechanism 51 and the lateral shaft 31 move in the front-rear direction on the guide rail 52 by the cam mechanism 54, and the outer tube 19b attached to the slide block 51 is moved along the outer periphery of the inner tube 19a. It will extend along the surface. As shown in FIG. 8, the sensor unit 14 moves between the distance x2 in conjunction with the slide block 51 sliding in the front-rear direction between the distance x1. Since the slide block 51 and the sensor unit 14 are connected via the horizontal shaft 31 and the vertical shaft 34, the distances x1 and x2 are the same distance. Further, the distance x2 is set corresponding to the distance moved between the receiving holes 11a and 11b at the front and rear ends of the sorting block 12.

  On the other hand, as described in FIG. 5 of the first embodiment, the rotation of the inspection component passage unit 10 in the left-right direction is such that the vertical shaft 34 swings, so that the sensor unit 14 moves along the upper surface 20 of the distribution block 12. In this embodiment, the component sorting apparatus 50 is compact because it is driven by the reversing motor 33 disposed on the side of the frame 13. The driving force of the reversing motor 33 is transmitted to the sensor unit 14 via a pulley 62 and a driving belt 63 attached to one end of the horizontal shaft 31. As in the first embodiment, the distribution block 12 is a square member having a curved upper surface 20, and the upper surface 20 is provided with a large number of receiving holes 11 arranged in the vertical and horizontal directions.

Is preferably made of a coated metal material. This is because, for example, when a chip part with a metal foot coming out of the body is passed through the tube or pipe, the inner surface is scraped with the metal foot if the tube or pipe is made of a soft material. This is because the shavings may adhere to the chip part and deteriorate the quality. Such a problem does not occur if the inner peripheral surface is a coated metal material. Therefore, depending on the outer shape of the chip component to be inspected and the material of the surface, the component sorting apparatus 50 according to this embodiment may be effective. In the present embodiment, the tubes 19a and 19b are made into a double structure so that the tubes 19a and 19b can be expanded and contracted. On the other hand, since the distribution block 12 remains fixed, there is no problem even if many pipes 40a piped from the lower surface of the distribution block 12 are made of a metal material.

  In any of the above-described embodiments, the case where the chip component passes through the opening 23 of the sensor unit 14 has been described as being detected. However, the opening 23 may be passed through without detection. In the above embodiment, the distribution of the chip components has been described. However, the present invention can also be applied to the distribution of components other than chips.
