Description

Automatic pipe penetrating equipment

[ technical field ] A method for producing a semiconductor device

The present invention relates to an automatic tube threading apparatus, and particularly to an automatic tube threading apparatus used in a process of assembling a developing roller.

[ background of the invention ]

The developing roller is widely used in the fields of printers and copiers. The current common developing roller consists of a metal shaft center and conductive rubber which is sleeved outside the metal shaft center and tightly wraps the metal shaft center. The metal core may be an iron core or others. Because the rubber layer outside the metal shaft center is made of hard rubber, in order to improve the printing effect, the circumferential surface of the conductive rubber outside the metal shaft center is required to be polished, cleaned and the like, and finally, spraying is carried out, so that the parameters of the developing roller, such as the size surface smoothness, the surface flatness and the like, meet the precision requirement.

The current methods for combining a metal core and a conductive rubber are as follows:

the first mode is injection molding, i.e. the processed metal axle center is fixed in a mold, then prepared colloid is injected, and after molding, post-treatment such as end surface flattening, grinding and the like is carried out to obtain the size and the smoothness meeting the requirements.

And secondly, adopting a pipe penetrating mode, namely respectively processing the metal shaft center and the rubber pipe, and then sleeving the rubber pipe on the metal shaft center. At present, the process of sleeving the rubber tube on the metal shaft center adopts a semi-manual semi-automatic mode, namely, the rubber tube is cut manually according to the required size, then the cut rubber tube and the prefabricated metal shaft center are conveyed to a tube penetrating station manually, and the metal shaft center is penetrated into the rubber tube manually or by a machine. The manual pipe cutting, pipe conveying and pipe penetrating processing efficiency is low, the cost is high, and the quality of processed products is uneven. Even if can adopt the machine to wear the pipe, still need carry out artifical pipe cutting and send the pipe, though improved machining efficiency to a certain extent, nevertheless because pipe cutting and send the pipe still manual operation, machining efficiency still is not high, and the uneven problem of quality that artifical pipe cutting brought still can't be solved.
