Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to an installation inspection method for optoelectronic modules. Background Technology

[0002] In the manufacturing and assembly process of optoelectronic modules, the post-installation testing stage is crucial. Optoelectronic modules are usually installed on printed circuit boards (PCBs), and their installation quality directly affects the performance and reliability of the product.

[0003] Traditional inspection methods mainly rely on manual visual inspection or fixed-angle visual inspection systems, but these methods have problems such as low inspection efficiency, insufficient accuracy, and difficulty in fully covering multi-angle defects of modules.

[0004] Manual visual inspection is not only inefficient, but also prone to missed or false detections due to fatigue or subjective factors. Existing fixed vision inspection systems can usually only take pictures from a single angle (such as directly above), making it difficult to capture installation defects on the side of the optoelectronic module (such as tilting, offset, or poor welding), resulting in incomplete and inaccurate inspection results. Therefore, we propose an installation inspection method for optoelectronic modules. Summary of the Invention

[0057] The second ball is movably engaged with the inner wall of the second ball hole at the bottom end of the movable rod.

[0058] The technical effects and advantages of this invention are as follows:

[0059] (1) The present invention utilizes the setting of the moving mechanism and the adjusting mechanism. The first servo motor drives the lead screw to rotate. Under the meshing of the outer wall of the lead screw and the inner wall of the threaded hole, the top of the slider is in contact with the top of the inner wall of the fixed frame. This allows the slider to move with the rotation of the lead screw, thereby adjusting the position of the vision camera. During the movement of the slider, the rotating shaft drives the connecting rod to rotate through the meshing of the gear and the rack, causing the extrusion wheel to squeeze the connecting hose. This allows the connecting hose to complete the flow of liquid in the first liquid chamber and the second liquid chamber. This allows the hydraulic oil in the first liquid chamber to enter the second liquid chamber through the connecting hose, or the liquid in the second liquid chamber to enter the first liquid chamber through the connecting hose. This squeezes the first piston plate, thereby causing the first piston plate to drive the first connecting seat to rotate, thereby adjusting the shooting angle of the vision camera. This allows for multi-angle shooting of the optoelectronic module on the PCB board, thereby improving the accuracy of the detection.

[0060] (2) The present invention utilizes the dust removal mechanism and the air supply mechanism. When the first connecting seat rotates to adjust the shooting angle of the vision camera, the second piston plate will also rotate, thereby compressing the space inside the second connecting cavity or the first connecting cavity. This allows the air inside the second connecting cavity or the first connecting cavity to enter the corresponding connecting pipe through the first one-way valve, and then be discharged through the air passage and exhaust hole to blow towards the bottom of the protective glass, thereby cleaning the floating dust at the bottom of the protective glass, avoiding affecting the shooting of the vision camera, and further improving the accuracy of detection.

[0061] (3) The present invention utilizes the setting of the misaligned conveying mechanism, and with the cooperation of the driving mechanism, the second servo motor drives the synchronous wheel to rotate, thereby driving the synchronous belt to move, which in turn drives the connecting block to move. The movement of the connecting block drives the slide block to move. The slide block limits the guide block, so that the slide block moves and drives the guide block to move. The movement of the guide block drives the slide shaft to move. Due to the V-groove guiding the slide shaft, the guide block moves with the slide block, and the slide block also slides in the slide groove. This allows the pallet to move laterally when it moves longitudinally, so that the two pallets can be misaligned when they are side by side on the workbench. This allows the pallets at the pick-up and place station and the inspection station to be replaced by misalignment, so that the inspection and pick-up of the PCB board are not carried out at the same station, thus improving the inspection efficiency.

[0062] (4) With the lifting mechanism, the truncated block is located at the PCB board pick-up and drop-off station. During the movement of the pallet, when the second ball contacts the outer wall of the truncated block, it can drive the movable rod to gradually rise, thereby causing the top plate to rise in the placement slot, which can lift the PCB board in the pallet, making it convenient for the staff to take it off, and further improving the convenience of the work. When the pallet moves from the pick-up and drop-off station to the testing station, without the support of the truncated block, the top plate can fall automatically under the action of gravity, causing the PCB board to fall into the placement slot, so that the pallet can stably drive the PCB board to the testing station for the installation and testing of the optoelectronic module.

[0073] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] This invention provides, for example Figures 1-9 The method for installation and testing of an optoelectronic module, as shown, includes the following steps:

[0075] Step 1: Place the PCB board with the optoelectronic module installed on the tray 102. The staff will place the PCB board at the pick-and-place station and remove the PCB board after inspection.

[0076] Step 2: The tray 102 is moved to the under of the vision camera 202 for inspection by the staggered conveying mechanism. The tray 102 with the new PCB board is moved to the inspection station by the staggered conveying mechanism, while the tray 102 with the inspected PCB board is moved to the pick-up and put-down station.

[0077] Step 3: The moving and adjusting mechanisms are used to move and rotate the vision camera 202 to perform multi-angle detection on the optoelectronic module on the PCB board. This allows the vision camera 202 to perform detection from both directly above and diagonally above the PCB board, increasing the number of detection samples and improving the accuracy of the detection.

[0078] As a further embodiment of the present invention, the moving mechanism includes a fixed frame 201, a first connecting seat 301, a lead screw 303, a slider 302, and a first servo motor 305. A misaligned conveying mechanism is disposed below the fixed frame 201. The first connecting seat 301 is disposed inside the fixed frame 201. A vision camera 202 is mounted on the bottom end of the first connecting seat 301. The lead screw 303 is rotatably connected to the inner wall of the fixed frame 201. An adjusting mechanism is disposed between the slider 302 and the first connecting seat 301. A threaded hole 304 is provided on one side of the slider 302. The outer wall of the lead screw 303 is threadedly connected to the inner wall of the threaded hole 304. The first servo motor 305 is mounted on the fixed frame 201. On the outer wall, the output end of the first servo motor 305 is connected to one end of the lead screw 303. The first servo motor 305 drives the lead screw 303 to rotate. With the engagement of the outer wall of the lead screw 303 and the inner wall of the threaded hole 304, and the top of the slider 302 being in contact with the top of the inner wall of the fixing frame 201, the slider 302 can move with the rotation of the lead screw 303, thereby adjusting the position of the vision camera 202. At the same time, with the cooperation of the adjustment mechanism, the shooting angle of the vision camera 202 can be adjusted, so that the optoelectronic module on the PCB board placed on the tray 102 can be shot and inspected from multiple angles, ensuring the accuracy of the inspection.

[0079] The adjusting mechanism includes a connecting shaft 401, a first rotating cavity 402, a first fixed baffle 403, a first piston plate 404, and a connecting hose 407. The connecting shaft 401 is fixedly connected to the bottom end of the slider 302. A dust removal mechanism is provided inside the first connecting seat 301. The first rotating cavity 402 is opened inside the first connecting seat 301, and the connecting shaft 401 passes through the inside of the first rotating cavity 402. The first fixed baffle 403 is fixedly connected to the outer wall of the connecting shaft 401, and the first piston plate 404 is fixedly connected to the inner wall of the first rotating cavity 402. The first rotating cavity 402 is divided into a first liquid cavity 405 and a second liquid cavity 406 by the first fixed baffle 403 and the first piston plate 404. The two ends of the connecting hose 407 are respectively fixed. The connecting hose 407 and the slider 302 are both filled with hydraulic oil 408 and are inserted into the outer wall of the first connecting seat 301. The outer wall of the connecting hose 407 is provided with a liquid transfer mechanism. The connecting shaft 401 is fixed relative to the slider 302, that is, the first fixed baffle 403 is fixed. When the slider 302 moves, the hydraulic oil 408 in the first liquid chamber 405 enters the second liquid chamber 406 through the connecting hose 407, or the liquid in the second liquid chamber 406 enters the first liquid chamber 405 through the connecting hose 407. This can squeeze the first piston plate 404, thereby causing the first piston plate 404 to drive the first connecting seat 301 to rotate, thereby adjusting the shooting angle of the vision camera 202.

[0080] The pipetting mechanism includes a second connecting seat 501, a rotating shaft 503, and a gear 507. The front of the second connecting seat 501 is fixedly connected to the back of the slider 302. A third rotating cavity 502 is formed inside the second connecting seat 501. The middle part of the connecting hose 407 is inserted into the third rotating cavity 502. The outer wall of the connecting hose 407 is fixedly connected to the inner wall of the third rotating cavity 502. The rotating shaft 503 is rotatably inserted into the inner wall of the third rotating cavity 502. A connecting rod 504 is symmetrically fixedly connected to the outer wall of the rotating shaft 503. A rotating groove 505 is formed at the end of the connecting rod 504. A squeezing wheel 506 is rotatably connected to the inner wall of the rotating groove 505. Wheel 507 is fixedly sleeved at the end of rotating shaft 503 and located on the back of second connecting seat 501. A rack 508 is fixedly connected to the top of the inner wall of fixing bracket 201. The outer wall of gear 507 meshes with the bottom end of rack 508. Rotation of rotating shaft 503 drives connecting rod 504 to rotate, causing extrusion wheel 506 to extrude pressure on connecting hose 407. This allows connecting hose 407 to facilitate the flow of liquid in the first liquid chamber 405 and the second liquid chamber 406, similar to the principle of a peristaltic pump. In actual operation, when slider 302 moves first connecting seat 301 to the right, the meshing of gear 507 and rack 508... When the slider 302 moves the first connecting seat 301 to the left, the gear 507 rotates counterclockwise, causing the shaft 503 to rotate counterclockwise. This, in turn, causes the extrusion wheel 506 to press against the connecting hose 407, allowing the hydraulic oil 408 in the first liquid chamber 405 to flow through the connecting hose 407 into the second liquid chamber 406. This, in turn, causes the first piston plate 404 to rotate clockwise, which in turn causes the first connecting seat 301 to rotate clockwise. This allows the vision camera 202 to be aimed at the PCB board on the tray 102 for imaging. When the slider 302 moves the first connecting seat 301 to the left, the meshing of the gear 507 and rack 508 causes the gear to rotate counterclockwise. When 507 rotates clockwise, the rotating shaft 503 rotates clockwise, causing the extrusion wheel 506 to squeeze the connecting hose 407. This causes the hydraulic oil 408 in the second liquid chamber 406 to flow into the first liquid chamber 405 through the connecting hose 407. This causes the first piston plate 404 to rotate counterclockwise, which in turn causes the first connecting seat 301 to rotate counterclockwise. This allows the vision camera 202 to be aimed at the PCB board on the tray 102 and take pictures. As a result, the vision camera 202 can stably be aimed at the PCB board and take pictures during the movement, thereby improving the stability and accuracy of the inspection.

[0081] The dust removal mechanism includes a protective glass 601, a connecting frame 602, an air passage chamber 603, and a connecting pipe 605. The protective glass 601 is fixedly connected to the bottom end of the first connecting seat 301. The vision camera 202 is disposed inside the protective glass 601. The connecting frame 602 is fixedly disposed at the bottom of the protective glass 601. The air passage chamber 603 is symmetrically opened inside the connecting frame 602. The inner wall of the air passage chamber 603 is provided with exhaust holes 604 spaced apart. The connecting pipe 605 is symmetrically fixedly inserted into the top end of the connecting frame 602. The interior of the air passage 603 is connected to the interior of the connecting pipe 605. An air supply mechanism is provided between the connecting pipe 605 and the first connecting seat 301. When the vision camera 202 is adjusting and shooting, the air supply mechanism allows air to be blown into the air passage 603 through the connecting pipe 605, and then blown towards the bottom of the protective glass 601 through the exhaust hole 604, thereby cleaning the floating dust at the bottom of the protective glass 601, avoiding affecting the shooting of the vision camera 202, and further improving the accuracy of detection.

[0082] The air supply mechanism includes a second rotating cavity 606, a second fixed baffle 607, a second piston plate 608, a first one-way valve 612, and a second one-way valve 614. The second rotating cavity 606 is located inside the first connecting seat 301. A connecting shaft 401 passes through the interior of the second rotating cavity 606. One end of a connecting pipe 605 is fixedly inserted into the outer wall of the first connecting seat 301. The interior of the connecting pipe 605 communicates with the interior of the second rotating cavity 606. The second fixed baffle 607 is fixedly connected to the outer wall of the connecting shaft 401. The second piston plate 608 is fixed... The second rotating cavity 606 is connected to the inner wall of the second rotating cavity 606. The interior of the second rotating cavity 606 is divided into a first connecting cavity 609 and a second connecting cavity 611 by a second fixed baffle 607 and a second piston plate 608. A first one-way valve 612 is installed on the inner wall of the connecting pipe 605. A connecting hole 613 is symmetrically opened on the inner wall of the second rotating cavity 606. A second one-way valve 614 is installed on the inner wall of the connecting hole 613. When the first connecting seat 301 moves to the right and rotates clockwise, the second piston plate 608 also rotates clockwise, thereby causing the first connecting cavity 609 to... Air is compressed and then discharged through the first one-way valve 612 into the connecting pipe 605 on the right, and finally into the connecting frame 602 and discharged through the exhaust hole 604, thus cleaning the dust at the bottom of the protective glass 601. As the second piston plate 608 rotates clockwise, the space inside the second connecting cavity 611 increases, allowing external air to enter the second connecting cavity 611 through the second one-way valve 614 for pressure balance. When the first connecting seat 301 moves to the left and rotates counterclockwise, the second piston plate 608 also rotates counterclockwise. When the second connecting cavity 611 is moved, the space becomes smaller, allowing the air inside the second connecting cavity 611 to be discharged through the first one-way valve 612 on the left and the connecting pipe 605. Then, it is blown towards the bottom of the protective glass 601 through the air passage 603 and the exhaust hole 604 to clean the floating dust. At this time, the space inside the first connecting cavity 609 becomes larger, and external air enters through the connecting hole 613 on the right and the second one-way valve 614 to balance the air pressure. This prevents the first connecting seat 301 from moving in either direction, allowing the floating dust at the bottom of the protective glass 601 to be cleaned.

[0083] The misaligned conveying mechanism includes a worktable 101, a V-groove 701, a sliding shaft 702, and a limiting ring 703. A fixed frame 201 is fixedly connected to the top of the worktable 101. A tray 102 is symmetrically slidably disposed above the worktable 101. A lifting mechanism is provided at the top of the worktable 101. The V-groove 701 is symmetrically opened at the top of the worktable 101. A bottom groove 108 is opened at the bottom end of the tray 102. The top of the sliding shaft 702 is fixedly connected to the top of the inner wall of the bottom groove 108.

The slide block 704 is slidably disposed inside the movable cavity 707. A groove 705 is formed at the top of the slide block 704. The outer wall of the guide block 706 is slidably connected to the inner wall of the groove 705. The top of the connecting block 804 is fixedly connected to the bottom of the slide block 704. A limit mechanism is provided at the bottom. Synchronous pulleys 801 are symmetrically rotatably connected to the inner wall of the movable cavity 707. A synchronous belt 802 is driven between the two synchronous pulleys 801. One side of the connecting block 804 is fixedly connected to the outer wall of the synchronous belt 802. A second servo motor 803 is installed inside the movable cavity 707. The output end of the second servo motor 803 is fixedly connected to the top of one of the synchronous pulleys 801. The second servo motor 803 drives the synchronous pulley 801 to rotate, thereby driving the synchronous belt 802 to move, which in turn drives the connecting block 804 to move. The movement of the connecting block 804 drives the slide 707. 4. Movement: The guide block 706 is limited by the slide groove 705, which causes the slide block 704 to move, driving the guide block 706 to move. The movement of the guide block 706 drives the slide shaft 702 to move. Due to the guidance of the slide shaft 702 by the V-groove 701, the guide block 706 moves with the slide block 704, while the slide block 704 also slides in the slide groove 705. This allows the pallet 102 to move laterally while moving longitudinally, so that the two pallets 102 can be staggered when placed side by side on the workbench 101. This allows the inspection station and the PCB board handling station to be fixed, improving the convenience of work.

[0084] The limiting mechanism includes a wedge block 805, a wedge groove 806, and a first ball 808. The top end of the wedge block 805 is fixedly connected to the bottom end of the connecting block 804. The wedge groove 806 is opened at the bottom end of the inner wall of the movable cavity 707. The outer wall of the wedge block 805 is slidably connected to the inner wall of the wedge groove 806. The outer wall of the wedge block 805 is provided with a plurality of first ball holes 807. The first ball 808 is movably opened on the inner wall of the first ball holes 807. The outer wall of the first ball 808 is fitted with the inner wall of the wedge groove 806. By limiting the wedge block 805 through the wedge groove 806, the synchronous belt 802 can stably drive the connecting block 804 to move, thereby improving the stability of the driving mechanism.

[0085] The lifting mechanism includes a top plate 105, a movable rod 106, a frustum block 107, and a second ball bearing 111. A placement groove 103 is provided at the top of the tray 102, and a retaining groove 104 is provided at the bottom of the inner wall of the placement groove 103. The top plate 105 is inserted into the retaining groove 104. The top of the movable rod 106 is fixedly connected to the bottom of the top plate 105. A movable hole 109 is provided between the retaining groove 104 and the bottom groove 108, and the movable rod 106 is movably inserted into the inner wall of the movable hole 109. The bottom of the frustum block 107 is fixedly connected to the top of the worktable 101. A second ball hole 110 is provided at the bottom of the movable rod 106, and the second ball bearing 111 is movably engaged in the inner wall of the second ball hole 110. The frustum block 107... Located at the PCB board handling station, during the movement of the tray 102, when the second rolling ball 111 contacts the inclined outer wall of the frustum block 107, it can drive the movable rod 106 to gradually rise, thereby causing the top plate 105 to rise in the placement slot 103, which can lift the PCB board in the tray 102, making it easier for the staff to remove it, further improving the convenience of the work. When the tray 102 moves from the handling station to the testing station, without the support of the frustum block 107, the top plate 105 will automatically fall under the action of gravity, causing the PCB board to fall into the placement slot 103, so that the tray 102 can stably move the PCB board to the testing station for the installation and testing of the optoelectronic module.
