Description

Technical Field

[0001] This utility model belongs to the field of optical communication device manufacturing technology, and in particular relates to a jig for pressing and assembling optical modules. Background Technology

[0002] Optical communication device manufacturing refers to the entire process of processing tiny components such as optoelectronic functional chips, lenses, optical fibers, tube shells, and PCBs into core devices (such as TOSA, ROSA, BOSA, optical modules, etc.) that can perform functions such as optical signal transmission, reception, amplification, modulation, and splitting through precision mounting, bonding, gluing, packaging, and testing. Its precision, reliability, and consistency directly determine the transmission rate, distance, and cost of the optical communication system.

[0003] However, given the explosive growth in demand for optical modules, existing production lines still commonly use simple clamps or manual jigs to pre-press the dispensing shell and PCB board: This results in a lack of positioning references, uneven pressure distribution, and poor consistency in adhesive layer thickness; a lack of clearance structures makes electronic components easily damaged; and the operation relies heavily on worker experience, with lengthy clamping and unclamping times, and a single-piece pressing cycle of several minutes. This cannot meet the pace of small-batch, multi-variety production, and the yield rate drops significantly with increasing batch size, becoming a bottleneck restricting the manufacturing efficiency and reliability of optical modules. Therefore, designing a fixture for optical module pressing and assembly is essential. Utility Model Content

[0004] This utility model provides a fixture for crimping and assembling optical modules, aiming to solve the problems of slow speed, component damage, and low yield of the currently used traditional crimping methods.

[0005] This utility model is implemented as follows: a fixture for pressing and assembling optical modules includes: a loading unit, the loading unit including a base plate; and a cover plate unit mounted on the loading unit. The cover plate unit is used to uniformly press and fix the optical module housing and the PCB component board between the loading unit and the cover plate unit by magnetic attraction. The product unit is the object to be pressed and assembled.

[0006] Preferably, the loading unit further includes: a guide pin fixedly installed on the base plate, an A strong magnet fixedly installed on the top of the base plate, multiple sets of the A strong magnets being installed at equal intervals on the base plate, and clearance holes being provided on the top of the base plate.

[0007] Preferably, the loading unit further includes: a C-support surface formed on the clearance hole, an anti-release hole fixedly installed at one end of the base plate, an A-support surface formed on one side of the base plate, and two sets of A-support surfaces formed thereon, with the two sets of A-support surfaces symmetrically arranged on the base plate.

[0008] Preferably, the loading unit further includes: a B support surface formed on the A support surface, a limit post fixedly installed on the A support surface, and a D support surface formed on the A support surface.

[0009] Preferably, the cover plate unit includes: a cover plate body assembled on the top of the base plate, a B-type strong magnet fixedly installed on one side of the cover plate body, a viewing hole opened on one side of the cover plate body, a pressing surface opened on the top of the cover plate body, and a guide hole opened on the top of the cover plate body.

[0010] Preferably, four sets of B-type strong magnets and guide holes are provided, and the four sets of B-type strong magnets and guide holes are equidistantly arranged on the cover plate body. Two sets of pressing surfaces are provided, and the two sets of pressing surfaces are symmetrically arranged on the cover plate body.

[0011] Preferably, the product unit includes: a PCB board detachably mounted between the base plate and the cover plate body, the PCB board having a limiting hole, an electronic component being fixedly mounted on the top of the limiting hole, and a laser tube housing being fixedly mounted on the top of the PCB board.

[0012] Preferably, multiple sets of limiting holes are provided, and the multiple sets of limiting holes are equally spaced on the PCB board.

[0013] Compared with related technologies, the optical module crimping assembly fixture provided by this utility model has the following beneficial effects:

[0014] During operation, the operator first places the PCB board of the product unit on the base plate of the loading unit, aligning the limiting holes on the PCB board with the limiting posts on the base plate. Simultaneously, ensure the bottom of the laser tube housing is against support surface A, and the bottom surface of the PCB board is against support surfaces B and C. Electronic components on the PCB should avoid contact with support surfaces D and A. Next, apply adhesive around the contact area between the housing and the PCB board. Then, lift the cover unit, align the guide holes on the cover body with the guide pins on the base plate, and release. The strong magnet A on the base plate and the strong magnet B on the cover body magnetically attract each other, closing the cover unit with the loading unit. At this point, the pressing surface evenly presses against the laser tube housing, completing the crimping. The entire process is simple, quick, and precise, avoiding the problems of inaccurate positioning and component damage associated with traditional manual crimping. The magnetic closure method ensures uniform pressing force, improving crimping quality, increasing yield, and significantly shortening the single-piece crimping cycle. This effectively solves the problems of slow speed, component damage, and low yield associated with traditional crimping. Attached Figure Description
