Precast rod handling system and control method thereof

Abstract

The invention belongs to the manufacturing field of an optical fiber precast rod, relating to an automatical handing system of the optical fiber precast rod, and achieving automation to the handing process of the high temperature precast rod after finishing producing. The precast rod handling system comprises a three-direction moving device, a control center and a precast rod lifting device; the three-direction moving device comprises an X axial shaft, an X axial moving guide rail, an X axial lead screw, an X axial moving servo motor, a Y axial plate, a Y axial moving guide rail, a Y axial lead screw, a Y axial moving servo motor, a Z axial plate, a Z axial driving cylinder, a Z axial arm, a supporting rod bracket, an emitter and a receiver. The control method of the precast rod handling system comprises: lifting the precast rod to a rod unloading position; moving the Y axial plate to move along X axis, controlling a server to record the position of the Y axial plate two times; calculating a difference value to obtain the diameter of the precast rod; moving the Z axial plate to move along Y axis; after the supporting rod bracket is close to a proper position along Z axis direction towards the precast rod, stopping; moving the supporting rod bracket along the Y axis, unloading the precast rod; and back moving the precast rod.

Description

technical field [0001] The invention belongs to the field of optical fiber preform manufacturing, and relates to an automatic loading and unloading system for optical fiber preforms. It adopts hydraulic or pneumatic methods to automate the loading and unloading process of high-temperature preforms after production, ensures the safety and reliability of loading and unloading rods, and improves production and operation efficiency. Background technique [0002] At present, with the increasing demand for domestic preform rods, many domestic companies have invested in the preform rod industry. With the intensification of competition, in order to reduce costs and increase profits. A number of manufacturers have begun to gradually increase the diameter of the preform produced. The increase of the rod diameter also leads to the increase of the weight of the preform rod. In the past, the loading and unloading process of the preform was manually operated. When the rod diameter incre...

AI Technical Summary

Problems solved by technology

When the rod diameter increases and the weight increases, it becomes more and more difficult for the operator to manually load and unload the rod. If one is not careful, the preform may hit the equipment or other bodies, and the surface of the preform will be damaged. , the purity requirements are very high, as long as the surface is damaged, basically the rod will be scrapped, which will cause a lot of loss

Therefore, this loading and unloading method has been impossible to achieve safe loading and unloading, and there are potential safety hazards in the loading and unloading process.
