2results about How to "Adjust movement speed" patented technology

The utility model discloses a precision assembly machine with an automatic material sorting function, and particularly relates to the technical field of precision assembly equipment, the precision assembly machine comprises a supporting base, a collecting container and a conveying and arranging track, vibration motors are installed on the two sides of the outer surface of the collecting container, the collecting container is arranged above the supporting base, and the conveying and arranging track is arranged above the collecting container. A collecting cover is welded to the end, away from the collecting container, of the conveying and arranging rail, a limiting conveying pipe is arranged at the bottom of the collecting cover, a rolling ball rail is arranged at the bottom of an inner cavity of the rotating seat, and a rotating disc is installed in the inner cavity of the rotating seat. A large number of sealing rings can be contained in the collecting container, under the combined action of vibration and gravity, the sealing rings enter the conveying and arranging track and slide downwards along the track, the height of the sealing plate is controlled and adjusted, and the moving speed and the distance of the sealing rings in the track can be adjusted. And the sealing rings can be discharged from the conveying track one by one in order to be sequenced and assembled, so that the assembling efficiency and quality are remarkably improved.

The utility model relates to an automatic anti-falling device, which belongs to the field of semiconductor production equipment and comprises a fixed frame, a movable plate is arranged on one side of the fixed frame, an air cylinder is connected onto the fixed frame, a piston end of the air cylinder is fixedly connected with the movable plate, and the movable plate is controlled by the air cylinder to move towards or away from the fixed frame. A first spring is arranged between the movable plate and the fixed frame, the two ends of the first spring are connected with the fixed frame and the movable plate respectively, the first spring is in a stretched state, a movable rod is movably arranged on the fixed frame in a penetrating mode, the movable rod is parallel to the moving direction of the movable plate, and one end of the movable rod is fixedly arranged on the movable plate. When an air source connected with the sealing cutter breaks down, the moving rod moves through the elastic acting force of the first spring, so that the supporting plate supports the sealing cutter, the sealing cutter is prevented from continuously descending to the position of a product to damage the product, and the anti-falling effect of the sealing cutter is achieved.
