[0049] Secondly, this invention discloses a dual-FA coupling method, comprising the following steps:

[0050] Control the power-on module to power the PCB board;

[0051] Control the first multi-degree-of-freedom adjustment mechanism to clamp the first FA material and transfer the first FA material to a preset first posture detection station; and control the second multi-degree-of-freedom adjustment mechanism to clamp the second FA material and transfer the second FA material to a preset second posture detection station;

[0052] Collect image information of the first FA material and the second FA material;

[0053] The attitude data of the first FA material is obtained based on the image information of the first FA material, and the attitude data of the second FA material is obtained based on the image information of the second FA material.

[0054] Based on the attitude data of the first FA material, the first multi-degree-of-freedom adjustment mechanism is controlled to rotate and adjust the first FA material so that the mounting reference surface of the first FA material is parallel to the first preset mounting plane of the PCB board, thus completing the attitude calibration of the first FA material. Based on the attitude data of the second FA material, the second multi-degree-of-freedom adjustment mechanism is controlled to rotate and adjust the second FA material so that the mounting reference surface of the second FA material is parallel to the second preset mounting plane of the PCB board, thus completing the attitude calibration of the second FA material.

[0055] The first and second multi-degree-of-freedom adjustment mechanisms are controlled to move the first FA material and the second FA material, which have been calibrated in attitude, to their respective preset coupling positions along their respective preset trajectories.

[0056] The first and second multi-degree-of-freedom adjustment mechanisms are controlled to adjust the position and orientation of the first and second FA materials to execute the coupling light-finding process. During the coupling light-finding process, the optical power detection value after the first and second FA materials are coupled is collected. When the optical power detection value is stable for a set time and within the preset optical power range, the coupling light-finding process is determined to be completed, and the first and second multi-degree-of-freedom adjustment mechanisms are controlled to lock the relative coupling orientation of the first and second FA materials.

[0057] In some embodiments, after the coupling and light-finding process is completed, the following steps are also included:

[0058] Control the dispensing mechanism to dispense adhesive, and stick the first FA material and the second FA material onto the PCB board;

[0059] The curing mechanism controls the curing of the adhesive.

[0060] In some embodiments, acquiring image information of the first FA material and / or the second FA material includes: acquiring visual images of the XZ plane, YZ plane, and XY plane of the first vision module;

[0061] When the first FA material is located at the first posture detection station, the first reflection module and the second reflection module reflect the XZ plane and YZ plane visual images of the first FA material to the imaging area of ​​the first vision module, respectively, so that the first vision module receives the XZ plane and YZ plane visual images reflected by the two reflection modules and acquires the XY plane visual images of the first FA material or / and the second FA material.

[0062] The present invention has at least the following beneficial effects:

[0063] This invention utilizes a coupling system to simultaneously and precisely adjust the position (X / Y / Z axis translation) and attitude (pitch, yaw, rotation) of the first and second FA materials, covering all the dimensional adjustment requirements for FA material coupling. This avoids the limitations of single-mechanism adjustment, and the entire process of this invention requires no manual intervention. Through mechanism collaboration and closed-loop feedback of optical power, the iterative process of "adjustment-detection-re-adjustment" can be automatically completed. Compared with manual light finding, this significantly shortens the coupling time and improves the efficiency of mass production.

[0064] This invention employs a combination of dual-reflection modules and a single camera to ensure that the mounting reference plane of the FA material is parallel to the preset mounting plane of the PCB board. This eliminates the need for a multi-camera layout, simplifies the hardware structure, and reduces costs. Furthermore, this invention simultaneously acquires attitude data and combines it with multi-axis high-precision adjustments to ensure that the parallelism error between the material and the PCB board is minimal.

[0147] The control flow of the coupling device of the present invention is as follows:

[0148] The PCB board is placed on the middle platform and clamped by the limiting fixture. The power module 3 clamps the PCB fixture 2 to power on the PCB board.

[0149] Place the first FA material and the second FA material on the left and right loading platforms 2-5 respectively and tighten them;

[0150] The first multi-degree-of-freedom adjustment mechanism 4, i.e., the left-hand six-axis coupling stage, moves to the first feeding position directly above the first FA material. The clamp opens to pick up the first FA material from the suction nozzle, and then closes to clamp the first FA material. The first FA material is then raised to the first posture detection station, i.e., the first recognition area. The first reflection module 11 and the second reflection module 12 reflect the XZ plane and YZ plane angles of the first FA material to the recognition area of ​​the first recognition camera. The first recognition camera recognizes the angle of the first FA material in the XY plane and rotates the first FA material to be parallel to the PCB board through the first multi-degree-of-freedom adjustment mechanism 4, i.e., the left-hand six-axis coupling stage.

[0151] Simultaneously, the second multi-degree-of-freedom adjustment mechanism 6, i.e., the right-hand six-axis coupling stage, moves to the position directly above the second FA material, i.e., the second feeding position. The clamp opens to pick up the second FA material from the suction nozzle, and then closes to clamp the second FA material. The second FA material is then raised to the second posture detection station, i.e., the second recognition area. The light shield 16 also moves to the second recognition area. The second recognition camera on the right and the third recognition camera below identify the angle of the second FA material in the XY plane. The second multi-degree-of-freedom adjustment mechanism 6, i.e., the right-hand six-axis coupling stage, rotates the second FA material to be parallel to the PCB board.

[0152] The left second multi-degree-of-freedom adjustment mechanism 6, i.e. the right-hand six-axis coupling stage, after the angle is corrected, moves the first FA material and the second FA material to the coupling position to perform coupling light search. The coupling light search is completed when the light power reaches the specified value.

[0153] The lens is attached to the PCB board by dispensing adhesive using a dispensing module;

[0154] The adhesive is cured by the curing module, thus completing the coupling of the dual FA lenses.

[0155] Based on the same inventive concept, this disclosure also provides a dual-FA coupling method. This dual-FA coupling method is based on the dual-FA coupling device provided in the previous embodiments. For a detailed description of the dual-FA coupling device, please refer to the content in the previous embodiments. The dual-FA coupling method includes the following steps:

[0156] The power supply module 3 controls the power supply to the PCB board;

[0157] Control the first multi-degree-of-freedom adjustment mechanism 4 to clamp the first FA material and transfer the first FA material to the preset first posture detection station; and control the second multi-degree-of-freedom adjustment mechanism 6 to clamp the second FA material and transfer the second FA material to the preset second posture detection station;

[0158] Collect image information of the first FA material and the second FA material;

[0159] The attitude data of the first FA material is obtained based on the image information of the first FA material, and the attitude data of the second FA material is obtained based on the image information of the second FA material.

[0160] Based on the attitude data of the first FA material, the first multi-degree-of-freedom adjustment mechanism 4 is controlled to rotate and adjust the first FA material so that the mounting reference surface of the first FA material is parallel to the first preset mounting plane of the PCB board, thus completing the attitude calibration of the first FA material. Based on the attitude data of the second FA material, the second multi-degree-of-freedom adjustment mechanism 6 is controlled to rotate and adjust the second FA material so that the mounting reference surface of the second FA material is parallel to the second preset mounting plane of the PCB board, thus completing the attitude calibration of the second FA material.

[0161] The first multi-degree-of-freedom adjustment mechanism 4 and the second multi-degree-of-freedom adjustment mechanism 6 respectively move the first FA material and the second FA material after attitude calibration to their respective preset coupling positions along their respective preset trajectories.

[0162] The first multi-degree-of-freedom adjustment mechanism 4 and the second multi-degree-of-freedom adjustment mechanism 6 are controlled to adjust the position and attitude of the first FA material and the second FA material to execute the coupling light-finding process. In the coupling light-finding process, the optical power detection value after the first FA material and the second FA material are coupled is collected. When the optical power detection value is stable for a set time and is within the preset optical power range, the coupling light-finding process is determined to be completed, and the first multi-degree-of-freedom adjustment mechanism 4 and the second multi-degree-of-freedom adjustment mechanism 6 are controlled to lock the relative coupling attitude of the first FA material and the second FA material.

[0163] In some embodiments, after the coupling and light-finding process is completed, the following steps are also included:

[0164] Control the dispensing mechanism to dispense adhesive, and stick the first FA material and the second FA material onto the PCB board;

[0165] The curing mechanism controls the curing of the adhesive.

[0166] In some embodiments, the optical fiber of the first FA material is connected to the first optical power detection module, and the optical fiber of the second FA material is connected to the second optical power detection module. A laser on the PCB emits light, which enters the first and second FA materials respectively, and is then detected by the first and second optical power detection modules. The first and second optical power detection modules are connected to a control unit, which transmits the detected optical power to the control unit. The control unit compares the detected optical power with a preset optical power value. If the deviation is within a set error range, it indicates successful optical coupling.

[0167] In some embodiments, during the coupled light-finding process, the first multi-degree-of-freedom adjustment mechanism 4 and the second multi-degree-of-freedom adjustment mechanism 6 are coupled and coupled simultaneously to find light, which can keep the first multi-degree-of-freedom adjustment mechanism 4 and the second multi-degree-of-freedom adjustment mechanism 6 in coordinated action and avoid collisions caused by excessive adjustment of a single mechanism.

[0168] In some embodiments, acquiring image information of the first FA material includes: acquiring visual images of the first vision module 10 in the XZ plane, YZ plane, and XY plane;

[0169] When the first FA material is located at the first posture detection station, the first reflection module 11 and the second reflection module 12 reflect the XZ plane and YZ plane visual images of the first FA material to the imaging area of ​​the first vision module 10, respectively, so that the first vision module 10 receives the XZ plane and YZ plane visual images reflected by the two reflection modules and acquires the XY plane visual image of the first FA material.

[0170] This invention employs a linear module to drive the object's translation and a rotary module to drive its rotation. The linear and rotary modules can be added or removed as needed for various movement adjustment mechanisms. Different drive methods can be selected for the linear and rotary modules, such as electrically controlled or manually controlled modules. For example, the linear module can be configured as an electric slide, pneumatic slide, or manually controlled linear module, etc. The linear modules are configured to drive the material along a straight line; for example, the X-axis linear module is configured to drive the material along the X-axis, the Y-axis linear module is configured to drive the material along the Y-axis, and the Z-axis linear module is configured to drive the material along the Z-axis.

[0171] The various moving adjustment mechanisms are not limited to the above embodiments and can be adjusted as needed. For example, the dispensing moving adjustment mechanism can be set according to dispensing requirements, and the UV moving adjustment mechanism can be set according to UV moving requirements.

[0172] Each vision module is connected to a control unit, and each vision module transmits the acquired images to the control unit. The control unit receives the images transmitted by the vision modules and performs image analysis to assist in automatic coupling.

[0173] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
