Abstract: A clamping mechanism automatically adaptable to change of thickness of printed circuit board includes: a frame body having two parallel rail seats; two clamping rail members respectively mounted on the rail seats for clamping a printed circuit board, each clamping rail member including a first clamping rail and a second clamping rail spaced from each other by a clamping gap; and two adjustment units for adjusting the clamping gap of the clamping rail members. Each the adjustment unit includes: a support section mounted on the frame body to provide a support face; a connection section, one end of the connection section being affixed to the first clamping rail, the other end of the connection section being positioned above the support face; and a floating section positioned between the connection section and the support section and supported on the support face to apply a resilient support force to the connection section.

Abstract: A servo control apparatus for a linear motor comprises a position feedback device, a driver and a position compensating device that are connected with one another. The servo control apparatus is electrically connected to the linear motor. By such arrangements, it can not only improve the precision of the displacement of the linear motor, but also make the movement of the linear motor relatively smooth.

Abstract: A chip-guiding structure of a linear motor processing machine comprises an outer cover covers an outer portion of a processing head and can be moved along with a mover and a processing head of the linear motor. A rear end of the outer cover is fixed to the mover to form a closed condition, and a front end of the outer cover is outward expanded to form a spraying mouth. The outer cover is formed with an air inlet for insertion of one end of a guiding pipe of an air compressor, enabling the high pressure gas to transport into the outer cover from the guiding pipe via the air inlet. Thereby, the chips produced during the processing course will be blown out of the spraying mouth, so as to prevent the chips from entering the important components of the motor.

Abstract: A rod-adjusting structure for a rod type linear motor, at least one end or end surface of the rod is provided with a scale, and a body of the linear motor is formed with an index located correspondingly to the scale of the rod. When assembling the rod, the index can be pointed to one of the reticles of the scale to serve as an assembly reference. After a period of use, if the rod is deviated, such arrangements can adjust the rod to return to the origin position.
