Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] A fixture for laser emitter detection, comprising a cuboid fixture seat 1, a fixture fixing adjustment hole 2 is arranged on the front side of the cuboid fixture seat 1, and a fixture fixing adjustment hole 2 is arranged on the cuboid fixture seat 1 above the fixture fixing and adjusting hole 2. The jig fixes the top wire 3, and a jig adjustment and fixing shaft 5 is arranged on the rear side of the rectangular jig lower plate 4, and the rectangular jig lower plate 4 is movably inserted into the jig fixing adjustment hole 2 through the jig adjustment and fixing shaft 5, and the jig fixes the top wire 3. Connected with the jig adjustment fixed shaft 5, a rectangular groove 6 is arranged at the front end of the upper surface of the rectangular jig lower plate 4, and a left swing rod pinch shaft 13 and a right swing rod are respectively arranged in the rectangular groove 6 ...

Abstract

The invention discloses a clamp for testing a laser transmitter. The clamp settles a problem of low testing consistency of chips which are adhered on the laser transmitter. A rectangular clamp lower board (4) is movably inserted in a clamp fixing adjusting hole (2) through a clamp adjusting fixing shaft (5). By means of matching among an extension spring (14), a tapered column (15), a left swing rod clamp (12) and a right swing rod clamp in a measuring clamp, clamping of the laser transmitter on the measuring clamp is realized. A clamp positioning board (27) on a measuring table (26) finishes a laser transmitter testing positioning task through a positioning annular worktable which is arranged in a laser transmitter testing positioning trough (10) and a positioning pin (25) that is fixedly arranged on the front end surface of a vertical plate of an L-shaped clamp upper board (7). The centering value of a chip assembly, the focal length of the chip assembly and a chip rotation angle are quickly calculated through a computer which is connected with an image camera (28). The position precision value of the laser transmitter is quickly measured.

Description

technical field [0001] The invention relates to an attachment accuracy measuring device for attaching a chip on a laser emitter, in particular to a detection fixture for attaching a chip on a laser emitter. Background technique [0002] In the field of optical communication, optical signals are transmitted through optical fibers. During the transmission of optical signals, due to the limited transmission power, several optical transceivers composed of laser transmitters and receivers are set on the transmission line to act as relays. module. After the laser transmitter in the optical transceiver module is mounted through the eutectic process, when the mounting process is completed, the accuracy of the mounting position of the laser transmitter needs to be tested, and the next process can only be carried out after the test is passed. Production. The existing detection method is to place the mounted laser transmitter on the detection board, then place the detection board und...
