Description

Technical Field

[0001] The invention relates to an automatic coupling device for an optical communication module, belonging to the technical field of optical communications. Background Art

[0002] Optical communications refers to the transmission of data and information via optical fiber networks, encompassing multiple stages from device to system manufacturing. Optical communications have experienced rapid growth due to their wide bandwidth, high capacity, long relay distances, strong anti-interference capabilities, and high confidentiality. Since the 1990s, optical communications have become the primary means of transmitting telecommunications services worldwide.

[0003] In recent years, thanks to national support for the optical communications industry, the industry has experienced rapid growth, resulting in increasing demand for optical communications products. Simultaneously, the barriers to entry for optical communications production have been lowered, leading to the emergence of a large number of optical module manufacturers. Due to factors such as company background, service targets, and capabilities, the dimensions of laser submodules designed and produced vary widely, leading to the use of various types of coupling fixtures. These fixtures differ in their production processes, resulting in varying product quality, yield rates, and costs. This has led to increasingly fierce competition, a wide range of product quality, and increasingly demanding requirements from equipment manufacturers for optical module products.

[0004] In the above situation, in order to meet the requirements of quality, output and price, a new production process is needed to ensure production efficiency, reduce coupling costs, maintain stable product quality and product qualification rate. The automation of optical communication module production coupling has become an inevitable trend. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic coupling device for an optical communication module, which can effectively reduce interference from human factors and improve the processing yield, while also improving the positional accuracy in the vertical direction between the lens to be bonded and the PCB board, and also realize elastic limiting of the Z-axis movable seat to ensure the positional accuracy of the Z-axis movable seat.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic coupling device for an optical communication module, comprising a base, a carrier for mounting a PCB board, a lens clamping mechanism located above the carrier, and a Z-axis movable seat on which the carrier is mounted and which can move in the vertical direction. The lens clamping mechanism is mounted on the base via an XY drive platform and can move in the X and Y directions with the XY drive platform.

[0007] The top end of the rotary table is hingedly connected to a link rod, the lower end of the link rod is connected to the rotary table, and the upper end of the rotary table is hingedly connected to the movable seat arranged just below the driving block, and the upper end of the rotary table is hingedly connected to the movable seat. The upper end of the vertically arranged pin shaft is fixedly connected to the driving block, and the lower end of the pin shaft is movably connected to the movable seat so that the movable seat and the pin shaft can move relative to each other in the vertical direction. A first elastic member is provided between the driving block and the movable seat and is sleeved on the pin shaft. When the first elastic member is in an uncompressed state, the connection between the connecting rod and the rotating plate is located on one side of the vertical connection line between the movable seat and the rotating shaft.

[0008] A rotating rod is provided above the driving block, and the rotating rod can be rotatably mounted on a support seat and is located in the mounting groove of the support seat. One end of the rotating rod is exposed from the support seat and contacts the upper surface of the driving block, and the other end of the rotating rod exposed from the support seat is used to contact the upper end surface of the stop block provided thereunder, and a second elastic member located directly above the stop block is installed between the rotating rod and the support seat.

[0009] The further improved scheme in the above technical scheme is as follows:

[0010] 1. In the above solution, the ratio of the distance between the rotation center of the rotating rod and its one end above the driving block and the other end is 1:3~8.

[0011] 2. In the above solution, the stop block is mounted on an adjusting rod, and the adjusting rod is mounted on the support plate and can move in the vertical direction.

[0012] 3. In the above scheme, a vertical strip hole is opened at the lower end of the pin shaft, and a pin hole corresponding to the strip hole is opened on the movable seat. A pin passes through the pin hole on the movable seat and the strip hole on the pin shaft to movably connect the lower end of the pin shaft with the movable seat.

[0013] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0014] 1. The automatic coupling device of the optical communication module of the present invention has a lens clamping mechanism installed on the base through an XY driving platform and can move in the X and Y directions with the XY driving platform. A vertically arranged support plate is installed on the base at the outer side of the XY driving platform, and the Z-axis movable seat can be movably installed on one side surface of the support plate. The upper end of a vertically arranged pin shaft is fixedly connected to the driving block, and the lower end of the pin shaft is movably connected to the movable seat so that the movable seat and the pin shaft can move relative to each other in the vertical direction. When the first elastic member is in an uncompressed state, the connection between the connecting rod and the rotating piece is located on one side of the vertical connection line between the movable seat and the rotating shaft, which can effectively reduce the interference of human factors and improve the processing yield, and can also improve the position accuracy between the lens to be bonded and the PCB board in the vertical direction, and can also avoid the distance deviation caused by the slight fall of the Z-axis movable seat, thereby further improving the qualified rate of product processing.

[0015] 2. The automatic coupling device of the optical communication module of the present invention has a rotating rod provided above the driving block. The rotating rod can be rotatably installed on a support seat and is located in the installation groove of the support seat. One end of the rotating rod is exposed from the support seat and contacts the upper surface of the driving block. The other end of the rotating rod exposed from the support seat is used to contact the upper end surface of the stop block provided thereunder. A second elastic member located directly above the stop block is installed between the rotating rod and the support seat to realize elastic limiting of the Z-axis movable seat, avoid shaking and deviation caused by hard impact, ensure the position accuracy of the Z-axis movable seat, and also enable the rotating rod to automatically return to its initial position, thereby improving processing efficiency during multiple uses.
