A rotary positioning apparatus includes a fixing base, a rotation mechanism, two driving modules and a carrier. The rotation mechanism is disposed on the fixing base, the first driving module is disposed on the fixing base and coupled to the rotation mechanism to drive the rotation mechanism rotating around a first rotation axis relatively to the fixing base. The carrier has plural accommodating slots on a circular-arc surface thereof and is pivoted to the rotation mechanism through a second rotation axis passing through the curvature center of the circular-arc surface and perpendicular to the first rotation axis, on which the curvature center is located. The second driving module is disposed on the rotation mechanism and coupled to the carrier to drive the carrier rotating around the second rotation axis relatively to the rotation mechanism. An automatic pick-and-place system and an operation method using the rotary positioning apparatus are also provided.

Rotary positioning apparatus with dome carrier, automatic pick-and-place system, and operating method thereof

A rotatable locating apparatus including a fixing base, a rotatable rack, a first driving module, a carrier, and a second driving module is provided. The rotatable rack is pivoted on the fixing base through a first rotation axis. The first driving module is coupled to the rotatable rack to drive the rotatable rack rotating with respect to the fixing base along the first rotation axis. The carrier is provided with accommodating slots on an arc surface of the carrier, and the carrier is pivoted on the rotatable rack through a second rotation axis. The second rotation axis passes through a curvature center of the arc surface and is perpendicular to the first rotation axis. The curvature center is located on the first rotation axis. The second driving module is coupled to the carrier to drive the carrier rotating with respect to the rotatable rack along the second rotation axis.

Rotatable locating apparatus with dome carrier and operating method thereof

A cathode discharge device is provided. The cathode discharge apparatus includes an anode, a cathode and plural cathode chambers. The cathode is located inside the anode, where the cathode has plural flow channels and at least one flow channel hole, and the plural flow channels are connected to one another through the flow channel hole. The plural cathode chambers are located inside the cathode, wherein each of the cathode chambers has a chamber outlet and a chamber inlet connected with at least one of the flow channels.

Cathode discharge apparatus

A vacuum apparatus of rotary motion entry is disclosed, which comprises: a shaft sleeve, disposed on a cavity wall of a vacuum system; a rotary shaft, ensheathed by the shaft sleeve; and a transmission set, connected to the rotary shaft for driving the same; wherein, the rotary shaft is disposed passing through a hole formed on the base of the shaft sleeve while there are a first bearing, a second bearing, a sealing ring and a shaft seal being arranged separately inside the hole. Moreover, the shaft seal has a flake-like lip flange formed extending toward the center of the hole, that is capable of being extended away from the vacuum system by the inserting of the rotary shaft into the hole, and thereby, enabling the lip flange to engage with the rotary shaft tightly by the atmospheric pressure and thus isolating the outside world from the vacuum system.
