Description

  The present invention relates to a component loading apparatus.

  With the downsizing and higher performance of electronic equipment, the technology for manufacturing high-performance microelectronic components is very important. Electronic parts that are produced in large quantities may be packaged and sold in parts. However, manufacturers of electronic equipment perform a process of putting a large quantity of electronic parts into a component mounting device, so a large number of electronic parts are manufactured. In some cases, parts are packaged in trays.

  In the process of packaging a large number of electronic components in a tray, it is necessary to take out defective products of electronic components and package them in a state of being accurately aligned in the tray, and therefore an automated electronic component packaging system is used. In this electronic component packaging system, only non-defective products are selected except defective products, and then the selected electronic components are loaded on a tray. Therefore, a parts loading device is required.

  As such a component stacking device, there is known a component stacking device in which a stretchable component stacking sheet is sandwiched between a lower ring and an upper ring, and the upper ring is fixed to the lower ring by a clamping means ( For example, Patent Document 1). Specifically, in Patent Document 1, as a clamping means, a stopper claw 20 that is float-supported in an upright state by a spring is rotatably provided on an expanding base 18 (lower ring), and the tip of the stopper claw 20 is connected to a press ring 19 ( By applying to the upper ring), a clamping force corresponding to the spring force is applied.

  However, in the configuration of Patent Document 1, when the stopper claw 20 is rotated so as to be hung on or removed from the press ring 19, the stopper claw 20 is arranged so that the tip of the stopper claw 20 does not interfere with the press ring 19. An operation of retracting against the spring force is required. On the other hand, in Patent Document 1, in order to strengthen the clamping force by the stopper claw 20, it is necessary to strengthen the spring force. However, if the spring force is strengthened, it becomes difficult to perform the above-described retraction operation. For this reason, it is difficult to reinforce the clamping force by the stopper claw 20 in Patent Document 1, and the necessary clamping force may not be obtained.

It is sectional drawing of the principal part which shows operation | movement of the component loading apparatus of FIG. It is sectional drawing which shows schematically the structure of the expand apparatus incorporating the component loading apparatus of FIG.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an exploded perspective view schematically showing a configuration of a component stacking apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a main part showing an operation of the component stacking apparatus of FIG.

  A component stacking apparatus 100 according to this embodiment shown in FIG. 1 includes a component stacking sheet 10, a lower ring 20, an upper ring 30, and a clamping means 40.

  The component stacking sheet 10 is made of a stretchable sheet material such as rubber or synthetic resin, and a component (not shown) is stacked on the surface thereof. The surface of the component stacking sheet 10 can be made sticky and can have a high coefficient of friction against the component.

  The lower ring 20 is formed of an annular ring member. As shown in FIG. 2A, the lower ring 20 has a first support surface that supports the component stacking sheet 10 and is expanded downward. A first tapered surface 21 having a diameter is formed.

  The upper ring 30 is also formed of an annular ring member and is disposed above the lower ring 20. Further, as shown in FIG. 2A, the lower surface portion of the upper ring 30 faces downward as a second support surface that faces the first support surface (first taper surface 21) formed on the lower ring 20. A second tapered surface 31 that expands in diameter is formed. That is, the component stacking sheet 10 is held by being sandwiched between the first support surface (first tapered surface 21) of the lower ring 20 and the second support surface (second tapered surface 31) of the upper ring 30.

  The clamp means 40 is coupled to the lower ring 20 so as to be rotatable in the vertical direction and slidable in the inner and outer directions (radial direction), and to the clamp base 41 so as to be slidable in the vertical direction. The clamper 42 is provided. Further, the clamper 42 includes a claw portion 42a that is applied to the upper surface of the upper ring 30 in the clamped state shown in FIG.

  In this embodiment, a pair of holding blocks 22 are fixed to the lower surface portion of the lower ring 20 in order to couple the clamp base 41 to the lower ring 20 so as to be rotatable in the vertical direction and slidable in the inner and outer directions (radial direction). The hinge pin 24 is installed between the pair of holding blocks 22 by installing with bolts 23. The longitudinal direction of the hinge pin 24 is a horizontal direction orthogonal to the inner and outer direction (radial direction) of the lower ring 20. On the other hand, the clamp base 41 is formed with a long groove-like groove 41a for holding the hinge pin 24 so as to be slidable in the inner and outer directions (radial direction). Thus, the combination of the hinge pin 24 and the long groove 41a allows the clamp base 41 to slide in the inner and outer directions (radial direction) with respect to the lower ring 20, and the position slid most outward (FIG. 2C). 2 (d)), the hinge pin 24 can be rotated in the vertical direction about the rotation center. In this embodiment, the hinge ring 24 is provided in the lower ring 20 and the long groove 41a is provided in the clamp base 41. However, in contrast to the present embodiment, this embodiment may be implemented even if a long groove is provided in the lower ring 20 and a hinge pin is provided in the clamp base 41. Similarly to the example, the clamp base 41 can be coupled to the lower ring 20 so as to be rotatable in the vertical direction and slidable in the inner and outer directions (radial direction).

  In this embodiment, a screw mechanism is used to slidably couple the clamper 42 to the clamp base 41 in the vertical direction. Specifically, a through hole 41b through which the screw portion of the clamp screw 43 penetrates in the vertical direction is formed in the clamp base 41, and a screw hole 42b in which the screw portion of the clamp screw 43 is screwed in the vertical direction is formed in the clamper 42. is doing. Accordingly, the clamper 42 is slid vertically with respect to the clamp base 41 by the rotation operation of the clamp screw 43, and is positioned (fixed) at a predetermined position.

  Furthermore, in the present embodiment, in order to make the clamper 42 slide smoothly in the vertical direction, a pair of guide pins 41c extending in the vertical direction is formed on the clamp base 41, and the pair of guide pins 41c are inserted into the clamper 42. A pair of guide holes 42b are formed. Contrary to this embodiment, a guide pin extending in the vertical direction is formed in the clamper 42, and a guide hole through which the guide pin is inserted is formed in the clamp base 41, as in the present embodiment. The direction sliding operation can be made smooth.

  When the component stacking sheet 10 is set in the above configuration, the component stacking sheet 10 is placed on the upper surface portion of the lower ring 20 and then the upper ring 30 is covered. Then, the component stacking sheet 10 is sandwiched and held between the first support surface (first tapered surface 21) of the lower ring 20 and the second support surface (second tapered surface 31) of the upper ring 30. Next, after the claw portion 42 a of the clamper 42 is hung on the upper surface portion of the upper ring 30, the clamper 42 is slid downward by rotating the clamp screw 43. Then, the upper ring 30 is pressed against the lower ring 20, and the clamped state shown in FIG. In this embodiment, in the clamped state, the clamp base 41 is in the position slid most inward.

  In order to release the clamped state, the clamper 42 is slightly slid upward by rotating the clamp screw 43 as shown in FIG. Thereafter, as shown in FIG. 2C, the clamp base 41 is slid outward most, and as shown in FIG. 2D, the clamp base 41 is rotated downward about the hinge pin 24 as a rotation center. If it does so, the nail | claw part 42a of the clamper 42 will not hook on the upper surface part of the upper ring 30, and a clamped state will be cancelled | released completely. If the upper ring 30 is lifted upward in this state, the component stacking sheet 10 can be removed.

  As described above, according to the component stacking apparatus 100 of the present embodiment, the clamper 42 constituting the clamp unit 40 is coupled to the clamp base 41 so as to be slidable in the vertical direction by the screw mechanism. Can be easily strengthened. Further, since the clamp base 41 is coupled to the lower ring 20 so as to be rotatable in the vertical direction and slidable in the inner and outer directions, the clamping means 40 is hung on and removed from the upper ring even if the clamping force is strengthened. Operation can be performed easily.

  Hereinafter, usage examples of the component stacking apparatus of the present invention will be described.

  FIG. 2 is a cross-sectional view schematically showing a configuration of an expanding apparatus incorporating the component stacking apparatus 100 of FIG. As shown in the figure, the component loading device of the present invention is suitably used for an expanding device.

  The expanding apparatus 200 includes a base part 210, a support part 220, and an elevating part 230, and the component stacking apparatus 100 is supported on the support part 220.

  The base part 210 includes a base plate 211, a base ring 213 is coupled to the base plate 211 via a stand 212, and an expand ring 214 is formed so as to rise from the inner peripheral part of the base ring 213.

  The support unit 220 includes a support plate 221 that is coupled to the upper surface of the upper ring 30 of the component stacking apparatus 100. The support plate 221 is coupled to a moving plate 223 that is screwed to the drive screw shaft 222. The moving plate 223 is supported by a plate guide 224 raised from the base ring 213 so as to be movable up and down. Thus, when the drive screw shaft 222 rotates, the moving plate 223 and the support plate 221 are moved up and down.

  The elevating unit 230 includes a drive motor 231, and the rotational force of the drive motor 231 is transmitted to the drive screw shaft 222 via the timing belt 232. That is, when the drive motor 231 is rotated in the forward direction or the reverse direction, the drive screw shaft 222 is rotated in the forward direction or the reverse direction, and the moving plate 223 and the support plate 221 are moved up and down accordingly. Since it is coupled to the support plate 221, it moves up and down together with the support plate 221. When the support plate 221 is lowered as shown in FIG. 3, the component stacking sheet 10 of the component stacking apparatus 100 is expanded by the expanding ring 214. As a result, the interval between the components stacked on the component stacking sheet 10 is increased, and the inspection and pickup of the components can be easily performed.
