Description

Technical Field

[0001] This invention relates to the field of optical module assembly, and more specifically to a modular automated assembly line for optical modules. Background Technology

[0002] With the rapid development of communication technology, especially driven by the demand for AI computing power, optical communication technology has seen an explosive increase in application demand. As the core component of optical communication systems for realizing photoelectric signal conversion, optical modules have also experienced an explosive increase in production demand.

[0003] Currently, optical module products in the industry are generally divided into an upper shell, a lower shell, and a circuit board that carries the corresponding optoelectronic conversion devices. Regarding the assembly of optical modules, the shell supplier, responsible for producing the structural components, typically manufactures the optical module shell and then sends it to the optical module manufacturer for the assembly of the aforementioned circuit board and corresponding testing processes to obtain an optical module product ready for market. Although the structure of optical module products appears simple, their assembly requires specific design considerations based on the application scenarios. These requirements include variations in shape, heat dissipation, waterproofing, and the type of fiber optic interface used. Assembling different optical module products is difficult to standardize and cannot be done on the same assembly line.

[0004] In other words, for the current assembly of optical module products, automated assembly lines developed for single products have high production costs because they cannot be compatible with the assembly of different products. However, manual assembly methods cannot guarantee production efficiency or product quality. Therefore, developing assembly lines that can be compatible with the assembly processes of different optical module products is of great technical and commercial value for reducing the production cost of optical module products and improving their production efficiency and yield.

A lifting platform is positioned at one end of the parallel-arranged upper conveyor belt and lower return belt, and is positioned to move up and down between the upper conveyor belt and the lower return belt. In a raised state, it connects to the tooling fixture from the upper conveyor belt, and in a lowered state, it transports the tooling fixture to the lower return conveyor belt. In the loading equipment, the unloading equipment, and each of the intermediate process equipment, the tooling fixture is positioned and raised by the tooling positioning lifting platform when transported by the upper conveyor belt, so that the corresponding equipment can perform corresponding processes on the optical module housing loaded in the tooling fixture. After the corresponding processes are completed, the tooling fixture is placed back on the upper conveyor belt for continued transport based on the descent of the tooling positioning lifting platform. Thus, when the corresponding intermediate process equipment is arranged along the upper conveyor belt between the loading equipment and the unloading equipment, the automated assembly line for optical modules is formed.

One of the left and right stops of the first loading position and one of the left and right stops of the second loading position are movably configured. This allows for the loading of upper and lower shells of different optical modules while ensuring the stability and accuracy of the positioning of the optical module shells loaded on the loading fixture by the corresponding equipment, based on the unilaterally movable structural design.

[0009] Another object of the present invention is to provide an automated assembly line for column-mounted optical modules, wherein at least one of the intermediate process devices in the automated assembly line is configured to perform a process of applying a heat dissipation film, wherein the heat dissipation film has a separate release film attached to one side and a common release paper attached to the other side, wherein the release film has an extension section extending independently from the side of the heat dissipation film, wherein the intermediate process device has a scraping stop, a negative pressure recovery port, a robotic arm, and a CCD vision guidance module, a heat dissipation film suction nozzle, and a tilting film clamp mounted on the robotic arm, wherein the CCD vision guidance module performs positioning based on image acquisition, and the heat dissipation film suction nozzle, under the movement control of the robotic arm, picks up the heat dissipation film from the release paper based on a position on the release film corresponding to the heat dissipation film. A heat dissipation film is applied, and under the movement control of the robotic arm, the extension section is positioned corresponding to the scraping stop and pressed to scrape the extension section obliquely upward within a fixed angle range. The oblique peeling film clamp extends when the extension section is obliquely scraped upward to obliquely clamp the end of the extension section. The heat dissipation film suction nozzle is positioned under the movement control of the robotic arm and pressed to apply the heat dissipation film to the film application position of the corresponding optical module housing. After the heat dissipation film suction nozzle releases the isolation film and retracts, the oblique peeling film clamp removes the isolation film from the heat dissipation film under the movement control of the robotic arm. After removing the isolation film, the isolation film is released at the negative pressure recovery port under the movement control of the robotic arm to recover the removed isolation film at the negative pressure recovery port.

[0010] To achieve at least one of the above objectives, the present invention provides a modular automated assembly line for optical modules. The modular automated assembly line includes tooling fixtures, a loading device, a unloading device, and multiple intermediate process devices mounted between the loading device and the unloading device.

When the tooling is conveyed to the tooling positioning lifting platform by the upper conveyor belt, it is positioned and raised by the tooling positioning lifting platform to facilitate at least the optical module housing loading process on the tooling. After completing the corresponding process, it is placed based on the descent of the tooling positioning lifting platform. The conveyor belt continues to transport the components; in each of the intermediate process devices, the tooling fixture is positioned and lifted by the tooling positioning lifting platform when it is transported by the upper conveyor belt, so as to perform corresponding processes on the optical module housing loaded on the tooling fixture, and after the corresponding processes are completed, it is placed back on the upper conveyor belt for continued transport based on the descent of the tooling positioning lifting platform; wherein in the unloading device, the tooling fixture is positioned and lifted by the tooling positioning lifting platform when it is transported by the upper conveyor belt, so as to perform at least the optical module product unloading process on the tooling fixture, and after the corresponding processes are completed, it is placed back on the upper conveyor belt for continued transport based on the descent of the tooling positioning lifting platform.

Under the movement control of the robotic arm, the film-peeling clamp releases the film from the heat dissipation film after the heat dissipation film nozzle releases the film and retracts. Under the movement control of the robotic arm, the film is released at the negative pressure recovery port based on the positioning so that the removed film can be recovered at the negative pressure recovery port.

Detailed Implementation

[0050] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0051] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0052] This invention provides a modular automated assembly line for optical modules, wherein the modular automated assembly line can adapt to the assembly processes of different optical module products based on the modular arrangement of equipment that matches the corresponding processes. This enables the modular automated assembly line to be compatible with the assembly processes of different optical module products, which is beneficial to reducing the production cost of optical module products and improving the production efficiency and yield of optical module products.

[0053] Specifically, the automated assembly line for optical modules can form a tooling transport return line based on the assembly of equipment that matches the corresponding process. In the state of loading optical module housings with corresponding tooling fixtures, the assembly process of optical module products is realized during the transport process of the tooling fixtures, and the tooling fixtures are reused after being returned to realize the automated batch assembly of optical module products.

[0054] For example, refer to Figures 1A to 1B of the accompanying drawings of the specification of this invention. Figure 4As shown, an automated assembly line for column-mounted optical modules according to an embodiment of the present invention is illustrated. The automated assembly line includes a tooling fixture 100, a loading device 10, an unloading device 20, and multiple intermediate process devices 30 adapted to be mounted between the loading device and the unloading device. The loading device 10, the unloading device 20, and each of the intermediate process devices 30 are equipped with a tooling positioning lifting platform (11, 21, 31) and an upper conveyor belt (12, 22, 32) and a lower return conveyor belt (13, 23, 33) arranged side-by-side. The loading device 10 is also equipped with a return carrier lifting platform 14. The material handling equipment 20 is also provided with a carrier return lifting platform 24. In the material handling equipment 10, the return carrier lifting platform 24 is located at one end of the upper conveyor belt 12 and the lower return belt 13, and is positioned to move up and down between the upper conveyor belt 12 and the lower return belt 13. In a lowered state, it connects to the tooling fixture 100 from the lower return belt 13, and in a raised state, it transports the tooling fixture 100 to the upper conveyor belt 12. When the tooling fixture 100 is transported by the upper conveyor belt 12 to the tooling positioning lifting platform 11, it is positioned and lifted by the tooling positioning lifting platform 11 to facilitate the execution of at least the optical module housing on the tooling fixture 100. The loading process, and after the corresponding process is completed, the tooling positioning lifting platform 11 is lowered and placed on the upper conveyor belt 12 for continued transport; wherein in the unloading equipment 20, the tooling 100 is positioned and raised by the tooling positioning lifting platform 21 when it is transported by the upper conveyor belt 22 to facilitate the execution of at least the optical module product unloading process on the tooling 100, and after the corresponding process is completed, it is lowered and placed on the upper conveyor belt 22 for continued transport, the carrier return lifting platform 24 is set at one end of the upper conveyor belt 22 and the lower return belt 23, and is... The equipment is positioned between the upper conveyor belt 22 and the lower return belt 23 to access the tooling fixture 100 from the upper conveyor belt 22 in a raised state and to transport the tooling fixture 100 to the lower return conveyor belt 23 in a lowered state; wherein in each of the intermediate process equipment 30, the tooling fixture 100 is positioned and raised by the tooling positioning lifting platform 31 when it is transported by the upper conveyor belt 32 to facilitate the execution of corresponding processes on the optical module housing loaded in the tooling fixture 100, and after the corresponding processes are completed, it is placed on the upper conveyor belt 32 for continued transport based on the descent of the tooling positioning lifting platform 31;The intermediate process equipment 30 is arranged between the loading equipment 10 and the unloading equipment 20 along an upper conveyor belt 32 and a lower return belt 33 arranged in parallel. This forms a tooling conveyor return line with the loading equipment 10 and the unloading equipment 20. Thus, with the optical module housing loaded on the tooling fixture 100, the assembly process of the optical module product is realized during the conveying process of the tooling fixture 100. Automated batch assembly of the optical module product is achieved based on the circulation of the tooling fixture 100 on the tooling conveyor return line. Correspondingly, the automated optical module assembly line can adapt to the assembly processes of different optical module products based on the arrangement of the intermediate process equipment 30 between the loading equipment 10 and the unloading equipment 20, thereby ensuring compatibility with the assembly processes of different optical module products. This helps to reduce the production cost of optical module products and improve their production efficiency and yield.

[0055] Furthermore, such as Figure 5 As shown, with the conveying direction of the loading device 100 on the upper conveyor belt (12, 22, 32) as the forward direction, the loading device 100 has a first loading position 101 and a second loading position 102 arranged side by side, and at least one left stop block (1011, 1021) is respectively provided on the left side of the first loading position 101 and the left side of the second loading position 102, and at least one right stop block (1012, 1022) is respectively provided on the right side of the first loading position 101 and the right side of the second loading position 102, wherein the first loading position... One of the left stop 1011 and the right stop 1012 of the first load position 101 is movably configured, and one of the left stop 1021 and the right stop 1022 of the second load position 102 is movably configured. In this way, while being compatible with the loading of the upper and lower shells of different optical modules on the first load position 101 and the second load position 102, the structural design of the first load position 101 and the second load position 102 being movable on one side ensures the stability and accuracy of the positioning of the corresponding equipment on the optical module shell loaded on the loading fixture 100.

[0056] It is worth mentioning that, in the description of the present invention, the upper conveyor belt (12, 22, 32) and the lower return belt (13, 23, 33) only correspond to the belt conveyor belt in function and do not constitute a limitation of conveying by the belt conveyor belt. For example, the upper conveyor belt (12, 22, 32) or the lower return belt (13, 23, 33) can also be a conveying structure that corresponds to the belt conveyor belt in function, formed by rollers arranged in parallel.

[0057] Furthermore, in this embodiment of the invention, the loading device 10 further includes a loading robotic arm 15A for performing the optical module housing loading process on the loading fixture 100. The loading robotic arm 15A is equipped with a CCD guiding module 151A for visual positioning and an optical module picking module 152A for picking up the optical module housing. Under the movement control of the loading robotic arm 15A, the optical module picking module 152A picks up the optical module housing based on its positioning on the corresponding tray. When the loading fixture 100 is positioned and raised by the tooling positioning lifting platform 11, the loading robotic arm 15A loads the picked-up optical module housing into one of the first loading position 101 and the second loading position 102 of the loading fixture 100 based on its positioning under the movement control of the loading robotic arm 15A.

[0058] Specifically, to ensure the accuracy of positioning during the loading process of the optical module housing, and to ensure the consistency and stability of the loading position of the optical module housing on the loading fixture 100, the loading equipment 10 is also equipped with a CCD guide module 16 that is opposite to the CCD guide module 151A mounted on the loading robotic arm 15A. Under the movement control of the loading robotic arm 15A, the optical module picking module 152A picks up the optical module housing based on its position on the corresponding tray. Based on the positioning of the optical module housing by the reverse-mounted CCD guide module 16 and the positioning of the loading fixture 100 by the CCD guide module 151A mounted on the loading robotic arm 15A, the picked-up optical module housing is loaded onto the loading fixture 100.

[0059] Furthermore, the loading device 10 also includes a full-tray loading module 17 and an empty-tray unloading module 18. The full-tray loading module 17 is used to stack trays containing optical module housings, and the empty-tray unloading module 18 is used to stack empty trays. The loading robotic arm 15A is also equipped with a tray picking module 153A for picking up trays. When the optical module housings in the top tray of the full-tray loading module 17 are all removed, the tray picking module 153A, under the movement control of the loading robotic arm 15A, moves the top tray to the empty-tray unloading module 18 based on positioning. The full-tray loading module 17 is vertically and vertically configured to stack trays containing optical module housings in a lowered state and to rise in a state where the top tray is removed to maintain the height range of the new top tray.

[0060] In particular, in this embodiment of the invention, in order to improve the compatibility of the automated assembly line for the array-type optical modules, the loading equipment 10 further includes a loading and flipping module 19 for flipping the optical module housing, so as to be compatible with the flipping requirements of the optical module housing in the loading process.

The CCD vision guidance module 351 is positioned based on image acquisition. The heat dissipation film suction nozzle 352, under the movement control of the robotic arm 35, picks up the heat dissipation film 200 from the release paper 202 at a position on the release film 201 corresponding to the heat dissipation film 200. Under the movement control of the robotic arm 35, it presses down on the extension section 2011, positioned at the scraping stop 34, to scrape the extension section 2011 obliquely upward within a fixed angle range. The angled film-peeling fixture 353... The extension section 2011 extends obliquely upward to clamp the end of the extension section 2011.

After the heat dissipation film suction nozzle 352 releases the isolation film 201 and retracts, the oblique film peeling clamp 353 peels the isolation film 201 from the heat dissipation film under the movement control of the robotic arm 35. Under the movement control of the robotic arm 35, the isolation film 201 is released from the negative pressure recovery port 36 based on the positioning to recover the peeled isolation film 201 at the negative pressure recovery port 36.
