Description

Precise packaging device and method suitable for MPO (MPO)

Technical Field

The invention relates to the technical field of MPO, in particular to a precise packaging device suitable for MPO and a precise packaging method for MPO.

Background

The MPO inner and outer spherical surfaces are plated with the film layers, the film layers plated on the MPO inner and outer spherical surfaces have extremely high requirements on compactness and finish, and the MPO of the glass reticular sheet is easy to deform, so that the requirements on a packaging process are extremely high, and the inner and outer spherical surfaces cannot be in direct contact with a packaged object and cannot be scratched or rubbed outside the requirements on temperature, humidity, cleanliness and the like, and meanwhile, deformation cannot occur. MPO film protection and deformation control therefore present significant challenges to packaging of MPO.

Two main clamping modes of MPO before packaging are a plug board type clamping mode and a rotary pressurizing type clamping mode. As shown in fig. 1a-1b, the plugboard type MPO clamp has the advantages that MPOs can be clamped for multiple pieces at one time, and the plugboard type MPO clamp has the disadvantages that during the process of loading and taking out MPOs, the edges of the plugboards are easy to scratch with grooves of rectangular boxes, so that the problems of damage and powder falling of film layers are caused. With reference to fig. 2a-2b, the rotary pressurizing type has the advantages that after the box is placed in the box, the MPO is pressurized from the side surface, the MPO surface film layer cannot be scratched, but the MPO clamping force cannot be estimated relatively accurately, so that the change of the MPO surface type has great uncertainty. Because the MPO manufacturing process is extremely complex, the development yield is low, and the development cost is extremely high.
