Description

Technical Field

[0001] The present invention relates to the technical field of visual inspection, and in particular to an installation inspection method for an optoelectronic module. Background Art

[0002] In the manufacturing and assembly process of optoelectronic modules, the post-installation inspection link 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 detection 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 visual inspection systems can usually only capture images from a single angle (such as directly above), making it difficult to capture installation defects on the side of optoelectronic modules (such as tilt, offset, or poor welding). As a result, the inspection results are incomplete and inaccurate. To this end, we propose an installation inspection method for optoelectronic modules. Summary of the Invention

[0016] Technical effects and advantages of the present invention: (1) The present invention utilizes the setting of the moving mechanism and the adjusting mechanism. The first servo motor drives the screw to rotate. When the outer wall of the screw is engaged with 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. The slider can move with the rotation of the screw, thereby adjusting the position of the visual camera. During the movement of the slider, the gear and the rack are engaged, and the shaft rotates to drive the connecting rod to rotate, so that the extrusion wheel squeezes the connecting hose, so that the connecting hose can complete the flow of liquid in the first liquid chamber and the second liquid chamber, so that the hydraulic oil in the first liquid chamber enters the second liquid chamber through the connecting hose or the liquid in the second liquid chamber enters the first liquid chamber through the connecting hose, so that the first piston plate can be squeezed, so that the first piston plate can drive the first connecting seat to rotate, thereby adjusting the shooting angle of the visual camera, so that the optoelectronic module on the PCB board can be photographed at multiple angles, thereby improving the accuracy of detection; (2) The present invention utilizes the arrangement of the dust removal mechanism and the air supply mechanism. When the first connecting seat is rotated to adjust the shooting angle of the visual camera, the second piston plate will also rotate, thereby compressing the space in the second connecting chamber or the first connecting chamber, so that the air in the second connecting chamber or the first connecting chamber enters the corresponding connecting pipe through the first one-way valve, and then is discharged through the air cavity and the exhaust hole to be blown to the bottom end of the protective glass, thereby cleaning the floating dust on the bottom end of the protective glass, avoiding affecting the shooting of the visual camera, and further improving the accuracy of detection; (3) The present invention utilizes the setting of the staggered conveying mechanism, and under the cooperation of the driving mechanism, the second servo motor drives the synchronous wheel to rotate, thereby driving the synchronous belt to move, which can drive the connection block to move, and the movement of the connection block drives the slide to move. The guide block is limited by the slide groove, so that the slide moves and drives the guide block to move, and the guide block moves and drives the slide shaft to move. Since the V-shaped groove guides the slide shaft, the guide block moves with the slide, and the slide also slides in the slide groove, so that the tray can move horizontally while moving longitudinally, so that the two trays can be staggered when they are side by side on the workbench, so that the trays of the pick-up and placement station and the inspection station can be staggered and replaced, so that the inspection and pick-up of the PCB board are not carried out at the same station, thereby improving the inspection efficiency; (4) The present invention sets a lifting mechanism, and the round table block is located at the PCB board pick-up and placement station. During the movement of the tray, when the second ball contacts the outer wall slope of the round table block, it can drive the movable rod to gradually rise, so that the top plate rises in the placement groove, and the PCB board in the tray can be lifted up, which is convenient for the staff to take it out, further improving the convenience of work. When the tray moves from the pick-up and placement station to the inspection station, without the support of the round table block, the top plate can automatically fall under the action of gravity, so that the PCB board falls into the placement groove, so that the tray can stably drive the PCB board to move to the inspection station for installation and inspection of the optoelectronic module.

The top plate 105 is inserted into the inner part of the card slot 104. The top of the movable rod 106 is fixedly connected to the bottom end of the top plate 105. A movable hole 109 is provided between the card slot 104 and the bottom groove 108. The movable rod 106 is movably inserted into the inner wall of the movable hole 109. The bottom end of the frustum block 107 is fixedly connected to the top of the workbench 101. A second ball hole 110 is provided at the bottom end of the movable rod 106. The second rolling ball 111 is movably carded on the inner wall of the second ball hole 110. The frustum block 107 is fixedly connected to the top of the workbench 101. Located at the PCB board picking and placing station, during the movement of the tray 102, when the second rolling ball 111 contacts the outer wall inclined surface of the frustum block 107, the movable rod 106 can be driven to gradually rise, thereby causing the top plate 105 to rise in the placement groove 103, and the PCB board in the tray 102 can be lifted up, making it convenient for the staff to remove it, further improving the convenience of work. When the tray 102 moves from the picking and placing station to the inspection station, without the support of the frustum block 107, the top plate 105 can automatically fall under the action of gravity, causing the PCB board to fall into the placement groove 103, so that the tray 102 can stably drive the PCB board to move to the inspection station for installation and inspection of the optoelectronic module.
