| 20090261537 | COLLET MOUNTING ASSEMBLY FOR A DIE BONDER - A collet mounting assembly for a die bonder comprises a collet mount having a first end attached to the die bonder and a second end opposite the first end with a cavity defined in the second end for receiving a shaft of the collet. The collet mounting assembly further comprises a fastener for securing the collet inside the cavity of the collet mount. A compression force is generated around the shaft of the collet received in the collet mount by the flexing of the fastener when it is attached to the collet mount, for securing the collet within the cavity of the collet mount. | 10-22-2009 |
| 20120013081 | CLAMPING AND RELEASING ASSEMBLY - A clamping and releasing mechanism includes a clamping and releasing assembly and a control member configured for effecting operation of the assembly. The assembly includes a collet, a biasing member, a rod member, and a retainer affixed to the rod member such that movement of the rod member relative to the collet causes a variation in the biasing force exerted by the biasing member. When the control member is moved in a first direction, the control member causes the rod member to move in a first direction relative to the collet and move the first part away from the second part. When the control member is moved in an opposite direction, the biasing member causes the rod member to move in an opposite direction and move the first part toward the second part. The mechanism is made of a few simple components, requires little maintenance and is self-contained. | 01-19-2012 |
| 20120235367 | CUTTER-TOOLING ASSEMBLY - A cutter-tooling assembly has a tool holder, a positioning chunk, a cutter and a collet. The tool holder has a through hole axially formed through the tool holder. The positioning chunk is screwed in the through hole and has a cavity. The cavity has multiple corners formed around an inner surface of the cavity. The cutter is inserted into the through hole and has multiple edges abutting the corners. Because the cross sectional shape of the cavity is multilateral and has multiple corners which the edges abut, the combination of the corners and the edges can prevent a relative rotation between the tool holder and the cutter and make the cutter securely connected with the tool holder. | 09-20-2012 |

When the releasing device is in a first position, the resilient positioning member is engaged in cuts in an outer periphery of a bit in an engagement position received in the driving hole. When the releasing device is moved to a second position, the bit is disengaged from the resilient positioning member to allow easy removal of the bit. | 11-08-2012 |
