  Next, an embodiment of a pinning device 100 according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 3 and 4, the pinning device 100 according to the present invention is roughly provided with a linear moving means 10, a clamping means 20, and a thrust means 30.

  The linear moving means 10 is attached to the third feed stage 240 (see FIG. 2), and for example, a pneumatic cylinder having the piston rod 11 that linearly reciprocates along the Z direction can be used.

  The clamp means 20 is connected to the drive body 21 connected to the piston rod 11 of the linear movement means 10 and the drive body 21 at a predetermined circumferential interval so that a driving force is generated in conjunction with the linear movement means 10. A plurality of pawl members 22 provided and a sleeve member 23 surrounding the driving body 21 are provided.

  The plurality of pawl members 22 form a clamping space 24 for clamping a pin between the pawl members, and the size of the clamping space 24 is controlled by the driving force of the driving body 21. Thereby, pinching / non-pinching of the pin by the pawl member 22 is switched as will be described later.

  The driving body 21 is a cylindrical cylinder member, and each pawl member 22 is disposed on the bottom surface of the driving body 21 so as to be capable of reciprocating in the radial direction of the driving body 21. A plurality of guide grooves 213 are provided. The guide groove 213 is formed to extend in a strip shape from the outside in the radial direction of the driving body 21 with respect to the central axis O direction of the clamping space 24.

  In addition, the driving body 21 includes a flange portion 214 that protrudes oppositely from both longitudinal side wall portions of each guide groove 213, and a slot 215 that extends in a band shape narrower than the groove width of the guide groove 213 by the flange portion 214. And an end opening 216 opened to the outside from the outer peripheral surface 212.

  Each pawl member 22 connects the slide part 221 slidably provided in the guide groove 213, the projecting part 222 projecting downward from the slide part 221 via the slot 215, and the slide part 221 and the projecting part 222. It is comprised with the connection part 223 to perform.

  The sleeve member 23 is provided to surround the drive body 21 and to shield the end opening 216 of the guide groove 213.

  The thrust means 30 is connected to the clamp means 20 and has a disk-like base 31 fixed to the bottom surface 211 of the clamp means 20 and a rod-like protrusion that is disposed in the clamping space 24 and protrudes perpendicularly from the base 31. Member 32.

  Here, as described later, the thrust member 32 is provided to prevent the pin 310 from sliding upward together with the pawl member 22 after the pin 310 is driven into the corresponding pin hole 410 (see FIG. 2). . In addition, in the said description, although the shape of the base 31 and the protrusion member 32 was specified, it is an example to the last and is not necessarily limited to these shapes.

  Next, the operation of the pinning device 100 according to the present invention will be described.

  As shown in FIG. 5, in order to sandwich a predetermined pin 310 by a corresponding pawl member 22, a first feed stage 220 and a second feed stage 230 are driven by a driving means (not shown) in the substrate processing machine 200. The third feed stage 240 and the pinning device 100 are each moved to the pin clamping position.

  When the pinning device 100 or the like moves to the pin clamping position, the piston rod 11 of the linear moving means 10 moves, and the corresponding claw members 22 are separated from each other while the clamping means 20 is lowered along the Z direction. . Accordingly, the corresponding pin 310 is surrounded in a state where the clamping space 24 is enlarged.

  Then, by driving the driving body 21, the pawl members 22 approach each other to narrow the clamping space 24 and clamp the corresponding pin 310. Thereafter, as the linear moving means 10 moves, the clamping means 20 moves upward, and the pins 310 come out of the tray 300 and are held by the pawl members 22.

  Next, as shown in FIG. 6, in order to drive the pin 310 sandwiched by the pawl member 22 into the pin hole 410 of the corresponding workpiece 400, the driving means (not shown) in the substrate processing machine 200 performs the first operation. The feed stage 220, the second feed stage 230, the third feed stage 240, and the pinning device 100 are each moved to the pin driving position.

  When the pinning device 100 or the like moves to the pin driving position, the piston rod 11 of the linear moving means 10 moves, and the pin 310 is inserted into the corresponding pin hole 410 while being surrounded by the clamping means 20 along the Z direction. Is done.

  When the clamp means 20 is lowered, the bottom of the thrust member 32 comes into contact with the upper end of the corresponding pin 310. By driving the driving body 21, the pawl members 22 are separated from each other, and the pin 310 that has been sandwiched is released. By the linear moving means 10, the clamping means 20 rises together with the pawl member 22 and is separated from the pin 310.

  In this manner, the pinning device 100 can take out the pins 310 of various sizes from the tray 300 and drive them into the corresponding pin holes 410 of the workpiece 400, so that the manufacturing efficiency can be improved.

  Further, when the pin 310 is driven into the corresponding pin hole 410, the thrust member 32 of the thrust means 30 contacts the pin 310, so that the pin 310 can be prevented from moving upward with respect to the pawl member 22. Therefore, even when the pin 310 held by the pawl member 22 is released, the pin 310 is not displaced.

  The sleeve member 23 is arranged so as to surround the driving body 21 and shield the end opening 216 so that the clamping means 20 has a good appearance. Different sleeve members may be used. If necessary, the sleeve member 23 may be omitted and the pawl member 22 may be configured to be movable.
