Description

Technical Field

[0001] The invention relates to a turntable feeding device, in particular to a novel turntable feeding machine. Background Art

[0002] In 3C parts processing, turntable machines are widely used for continuous loading, which are fast and efficient. The existing turntable machines use sensors and rotating motors to electronically control the position of the rotating disk between the rotating disk and the fixed base plate. This method has random errors and cumulative errors of the servo motor. The position of the rotating disk is difficult to control accurately, resulting in poor positioning of the material and difficulty in processing and positioning.

[0003] At the same time, the rotating disk and the fixed base plate of the turntable machine are supported by a roller assembly with constant height. The processing accuracy and installation accuracy of the fixed base plate make multiple standardized roller assemblies not on the same plane and cannot contact and support the rotating disk at the same time. In addition, the turntable machine has been running for a long time, and the roller wear phenomenon exists, which makes the roller assembly and the rotating disk separate. In the above two cases, the roller assembly is difficult to play a good supporting role, which makes the turntable slightly tilted during processing, the position of the sheet is offset, and it is difficult to process and position. In order to obtain a good processing benchmark, the existing method uses a gasket under the roller assembly to achieve the same height contact. Its defects are: first, the gasket is adjusted to a fixed size, and it is difficult to achieve a good adjustment for the randomly changing height compensation value required by the roller assembly; second, the adjustment requires measuring the height compensation difference. In a small space, it is difficult to measure accurately and it is difficult to obtain effective adjustment; third, in a small space, the roller assembly needs to be loosened, the gasket is placed, and then tightened, which is difficult to operate, takes a long time to adjust, and reduces the equipment utilization rate.
