Description
Technical Field
The invention relates to the technical field of short fiber assembly detection, in particular to a short fiber assembly length measuring device.
Background
Referring to fig. 1, fig. 1 is a schematic structural diagram of a short fiber assembly in the prior art, wherein the short fiber assembly comprises an optical port adapter, an optical fiber and an AWG (arrayed waveguide grating) chip, and one end of the optical fiber is coupled with the optical port adapter, and the other end of the optical fiber is coupled with the AWG chip. Specifically, the optical fiber is coupled and connected with the AWG chip through a tail pipe. In order to ensure that the short fiber assembly can be well coupled and mounted on a circuit board of an optical module, the length from the bottom surface of the convex edge of the optical port adapter to the output end of the AWG chip generally needs to be ensured to meet design indexes.
Because the optical fiber is weak, is easy to bend or incline, the output end of the AWG chip is easy to damage and crack, and is inconvenient to clamp and touch.
The existing method for measuring the length of the short fiber component is that a base is arranged, and a clamping groove for fixing the optical port adapter and a supporting table for supporting a chip tail pipe are arranged on the base. Through the design of structural height matching, after the optical port adapter and the AWG chip are respectively placed on the clamping groove and the supporting table, the central lines of the optical port adapter, the tail pipe and the AWG chip are positioned on the same axis, and then the required length is measured by using a measuring tool. In this way, the clamping grooves and the supporting tables with different shapes and heights are arranged on the base, due to machining tolerance (for example, ±0.03 mm) of the metal piece, the machining tolerance of 0.03mm exists at the bottom surface of the clamping groove, the tolerance of 0.03mm exists at the table surface of the supporting table, namely, after the clamping groove bottom surface of the clamp base and the table surface of the supporting table are placed by the AWG short fiber assembly, the overlapping height tolerance of 0.06mm exists at the height between the centers of the two optical fibers, namely, the centers of the actual optical port adapter, the optical fibers and the tail pipe end of the chip are not positioned on the same axis, and the measured fiber length is about 0.1mm shorter than the actual length due to the combination of the short fiber length (for example, 20 mm). The optical device is a high-precision product, and the length of the optical device is different by 0.1mm, so that poor installation can be caused, and the product is scrapped. And the shorter the actual component fiber length is, the larger the influence of the superposition height tolerance on the measurement accuracy is.
If two mechanical limiting parts or clamping parts are adopted to respectively clamp the optical port adapter and the chip end tail pipe, and the three-dimensional positions between the optical port adapter and the chip end tail pipe are adjusted simply through a mechanical movement mechanism, so that the centers of the optical port adapter and the chip end tail pipe and the optical fiber are positioned on the same axis, on one hand, the precision of the movement mechanism is insufficient, and high-precision fine adjustment cannot be realized, on the other hand, the two ends of the optical port adapter and the chip end tail pipe are required to be reduced in height difference and the two ends of the optical fiber are required to be pulled far away on the same axis, the conventional three-dimensional mechanical adjustment cannot be carried out in two directions simultaneously, if the height difference is reduced firstly, the optical fiber in the middle of the assembly is further bent, the adjustment amplitude is not well controlled and is easy to damage the optical fiber, and if the horizontal distance is regulated firstly, the pulling force is easy to form on the connecting points at the two ends of the optical fiber, and the short fiber assembly is easy to damage.
