Title:
OPTICAL FIBER ANGLE ADJUSTMENT DEVICE AND CHIP TESTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/142491
Kind Code:
A1
Abstract:
An optical fiber angle adjustment device, which relates to the technical field of optical fiber fixtures, comprises a base (5), a first adjustment base (10), a second adjustment base (1), a first adjustment mechanism and a second adjustment mechanism. The first adjustment base (10) is rotatably mounted on the base, the second adjustment base (1) is rotatably mounted on the first adjustment base (10), the first adjustment mechanism is arranged between the base and the first adjustment base (10), and the second adjustment mechanism is arranged between the first adjustment base (10) and the second adjustment base (1). By means of controlling the first adjustment mechanism, the first adjustment base (10) can rotate around the base (5), and by means of controlling the second adjustment mechanism, the second adjustment base (1) can rotate around the first adjustment base (10); and during the rotation of the first adjustment base (10) and the second adjustment base (1), the second adjustment base (1) carries an optical fiber to rotate and swing so as to adjust an angle of the optical fiber, so that a receiving end of the optical fiber is aligned with a collimating focusing lens to accurately receive an optical signal output by a chip. Further provided is a chip testing apparatus.
