Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] The pose detection, adjustment and alignment process of the flexible parallel platform is as follows: figure 1 shown. The flexible parallel platform is driven by six motors. By controlling the six motors, the terminal pose detection and adjustment of the flexible parallel platform is realized. In the past, the control of the six-degree-of-freedom flexible parallel platform was indirectly obtained by calculating the displacement of the grating ruler. For the terminal pose of the parallel platform, the macro-micro detection device designed now can directly detect the terminal pose. The detection device appears as a feedback during control. The macro-micro combined d...

Abstract

The invention provides a tail-end pose detection system and method for a flexible parallel platform with photoelectronic packaging. The system is composed of a moving platform, a fixed platform, a moving platform connecting element, and five sets of pose detection units. The five sets of pose detection units are used for detecting and controlling pose values with six freedom degrees of the moving platform in real time. In addition, the method includes macroscopic pose detection and microcosmic pose detection. During the macroscopic pose detection, five laser displacement sensors detect the pose of the moving platform. The overall detection system has advantages of small size and low cost. The moving platform connecting element is arranged below the fixed platform without any contact, thereby avoiding any interference to the motion of the moving plane. Two laser displacement sensors are arranged outside the flexible parallel platform, thereby avoiding increasing of the pressure on the moving platform. Besides, during the microcosmic pose detection, adjusting is carried out by using an optical power meter and fine tuning is carried out based on the light transmitting value of the optical power meter.

Description

technical field [0001] The present invention relates to the technical field of flexible parallel platform detection, and more specifically, to a system and method for detecting the position and posture of the end of a flexible parallel platform for optoelectronic packaging. Background technique [0002] Optoelectronic packaging is the process of optically aligning and coupling optoelectronic devices with input and output array fibers. The motion platform for optoelectronic packaging needs to achieve six-degree-of-freedom motion and sub-micron positioning accuracy. The parallel motion platform has the advantages of strong bearing capacity, good rigidity, compact structure, good dynamics and good positioning ability, which can make up for the traditional The structural precision of the tandem motion platform is poor, the error is accumulated, and the backlash cannot be eliminated. [0003] The flexible parallel platform has the advantages of high precision and large stroke, a...
