A device for installing parts, which can improve production efficiency by reducing the movement time of nozzles, the device includes a nozzle lifting device and a control device for controlling the movement position and movement timing of the nozzle movement device, wherein the control The device stores the position and height of the obstacle between the component feeder and the circuit board, and after the electronic component is photographed by the component camera, lowers the nozzle while it has passed the obstacle, or enables the nozzle to avoid the obstacle The route movement of the object. In the component mounting area, the nozzle is moved at the movement height in the component mounting area, and when the component is mounted, the nozzle is lowered from the movement height in the component mounting area. Therefore, the lifting stroke of the nozzle (5) can be reduced. Furthermore, the lifting of the nozzle is performed in an arcuate course.

The invention relates to a material gathering unit, which comprises a charging basket (9) and a briar dressing device; wherein, the charging basket (9) has one or more, each charging basket is provided with a cone-shaped collection port (18) which runs through two lateral surfaces of the whole charging basket, one end table-board of one of two wings of the collection port is a material receiving sloping bench (14) which inclines toward the centre of the collection port; the briar dressing device comprises a bracket arm seat (13) on a lateral wall (24) and a fixed bearing (10), an L-shaped bracket arm (12) and a hydraulic cylinder (11) which are rotatably connected together; wherein, the bracket arm seat on the lateral wall is arranged on one wing with the material receiving sloping bench (14) and corresponding to the internal inclined plane (22) of the collection port (18), the L-shaped bracket arm (12) and the hydraulic cylinder (11) are respectively rotatably connected with the bracket arm seat (13) and the fixed bearing (10), the charging basket (9) is also provided with a blanking cushioning device and an elevator mechanism. The material gathering unit is simple and flexible to be operated, has small shaking and low noise, thus improving workshop environment.

The invention provides a stage performance elevation stand dance practice anti-tumbling training device. The stage performance elevation stand dance practice anti-tumbling training device comprises ananti-tumbling cover, anti-tumbling cover supporting frames and an elevation mechanism; the center of a training base table is provided with a round groove, and the elevation mechanism is fixedly installed at the bottom of the inner side of the groove through bolts; an elevation practice stand is fixedly arranged on the top side of the elevation mechanism; and eight recording camera structures arearranged at equal intervals on the base table of the bottom side at the periphery of the training base table, and the focus points of the recording cameras are all at the position of the elevation practice stand. The anti-tumbling cover supporting frames of the stage performance elevation stand dance practice anti-tumbling training device are designed to be an arc-shaped frames, a bottom side endhead is rotatably fixed to the outer wall of the elevation practice stand through a rotary shaft, rotatable installation is beneficial for the anti-tumbling cover supporting frames to be freely opened and closed according to elevation, the arc-shaped structural design is beneficial for the anti-tumbling cover to be spaced from the anti-tumbling cover supporting frames at a certain distance, and thus the situation that someone falls down and is in touch with the anti-tumbling cover supporting frame to cause unnecessary damage is avoided.

The invention provides an elevator. A suspension length of a control cable is relative small relative to a lifting stroke. The elevator comprises a control cable, wherein one end of the control cable is connected with a lift well and another end is connected with an elevator car. In the elevator, the middle part of the control cable is supported by a movable lifting device and the movable lifting device lifts respective with the lifting of the elevator car in the lift well and the lifting distance of the movable lifting device is shorter than the moving distance of the elevator car. The movable lifting device comprises: a movable lifting rack connected with the control cable; a guide rail supporting the movable lifting rack to life in the lift well; and a driving device for making the movable lifting rack move along the guide rail. The lifting length of the control cable is reduced relative to the stroke of the elevator car.
