The invention discloses a high-speed mounted head which comprises a base, a Z-axis lifting mechanism, a theta angle rotating mechanism and a mounted shaft. The Z-axis lifting mechanism comprises a first bearing, a driven synchronous pulley, a pulley shaft, a second bearing, a clutch, a first locking nut, a bearing pressing plate, an angular contact bearing, a ball screw, a ball screw nut, a screw connection block and a brake; an output end of a lifting servo motor is connected with a driving wheel; and the first bearing and the driven synchronous pulley are sequentially installed on the upper section of the pulley shaft, and the second bearing and the clutch are sequentially installed on the lower section of the pulley shaft. According to the high-speed mounted head, the Z-axis lifting mechanism uses the servo motor, a synchronous belt, the clutch, the brake and a pair of ball screw pairs to be matched with one another for using so that simultaneous or independent upward and downward moving of a plurality of shafts can be achieved, mounting accuracy and efficiencies are improved, the mechanism is simplified, and costs of the whole mounted head are reduced.
Description
technical field [0001] The invention belongs to the technical field of placement machine equipment and relates to a high-speed placement head. Background technique [0002] Using high-speed placement technology to install integrated circuit components on PCB boards is an important way to improve installation efficiency and installation accuracy. The placement head is one of the most critical equipment of the placement machine, which directly affects the speed and accuracy of placement. [0003] At present, the placement head used by foreign high-speed placement machines is usually composed of a placement shaft, a linear bearing, a jacket, a synchronous pulley, a bearing, a servo motor, etc., and the placement shaft is made in the form of a spline shaft, and its outer side is opened symmetrically. The two arc grooves of the linear bearing are matched with the balls in the linear bearing to realize the infinite linear motion up and down; the linear bearing and a pair of deep ...
