The invention discloses an aluminum foil pinhole number detection device for medicine packaging, and relates to the technical field of medicine packaging, the aluminum foil pinhole number detection device comprises a workbench and a moving assembly, the top center of the workbench is provided with a lamp panel, and two ends of the top of the workbench are fixedly provided with side frames. After the aluminum foil is arranged above the lamp panel, the aluminum foil can shield light of the lamp panel and leak light at the pinhole of the aluminum foil, so that the light leak part can be shot and detected through the visual detection camera, and meanwhile, the motor drives the second reciprocating lead screw to rotate, so that the hanging seat can move on the polished rod, and different positions on the aluminum foil can be visually detected; in the process that the lifting seat moves to the toothed plate, the pulley seat is firstly attached to the side frame, so that the movement of the pulley seat is limited, a buffer spring is compressed, and the lifting seat extrudes the toothed plate at the moment, so that the toothed plate passes through a gear shaft, a transmission box, a first synchronous belt wheel set and a second synchronous belt wheel set, and first reciprocating lead screws on the two sides rotate at the same time; therefore, the position of the movable seat can be changed.

This invention relates to the field of welding technology and discloses a method for linkage between a welding robot and the positioning simulation of injection molded parts, comprising the following steps: Step 1: Constructing a dual-camera vision positioning system with a resolution of 4K and a positioning accuracy of ±0.05mm. After pre-processing and cleaning the injection molded part, it is placed on a positioning worktable. Image data of three preset feature holes on the injection molded part are simultaneously acquired by the dual cameras. The diameter of the holes is 5mm and the positional tolerance is ±0.1mm. Step 2: Performing grayscale enhancement and edge extraction processing on the acquired image data to accurately identify the center coordinates of the three feature holes. Combining the dual-camera calibration parameters, the translational deviation and rotational angle deviation of the injection molded part in the X and Y axes are calculated to generate a complete positioning deviation dataset. Step 3: Selecting RobotStudio simulation software. This invention achieves precise positioning: the 4K dual-camera vision system combined with a weighted iterative algorithm achieves a positioning accuracy of ±0.05mm, effectively avoiding glare interference and accurately capturing the deviation data of the injection molded part.

The device ensures light conduction and imaging effects by accurately assembling all parts. The dividers can be replaced to expand and differentiate pattern styles, the problem that a traditional sighting telescope is fixed in dividers and colors is solved, the dividers are adaptive to different sighting scenes, the sighting flexibility and accuracy are improved, and the dividers are suitable for various sighting telescope devices.

The application belongs to the technical field of power distribution line inspection, and provides an insulator crack-light spot distinguishing method and system. In aerial unmanned aerial vehicle inspection, through planning a closed track and synchronous shooting of three exposure levels, cooperating with a double-branch detection network, chain geometry topology constraint and one-dimensional multi-flow graph convolution, the candidate crack detection is realized by using high light / dark line double-branch lightweight convolution to access the double-branch detection network. The candidate frame is aligned with the disc edge and the three-exposure local is cropped by geometric matching, and the multi-dimensional features are extracted. After the saturation mark is used to attenuate the high light channel, the features are assembled into a chain graph in physical order, and the cross-disc coherent dark lines are captured. Finally, the crack probability is output by the full connection layer, the mirror reflection is suppressed, the real cracks are realized, the false positives and false negatives are effectively reduced, and accurate basis is provided for power outage maintenance decision.

This invention discloses a back-contact solar cell and its mark point fabrication and positioning method, belonging to the field of solar cells. The back side of the silicon substrate of this solar cell has several pads arranged in an array, several fine grid lines connecting the pads, and at least one pair of edge mark points. The edge mark points are located near the side of the cell perpendicular to the extension direction of the interconnects. The vertical distance from the geometric center of the edge mark point to the aforementioned side is 1.0~4.0 mm. The edge mark point is located between two rows of pads adjacent to it. Two fine grid lines adjacent to the edge mark point are separated by the edge mark point, and the distance between the edge mark point and the separating edge of the fine grid line is greater than or equal to 20 μm. The above-mentioned edge mark point setting can achieve high-precision positioning and enable the interconnects and pads to form a more complete metallurgical bond, improving pull strength and yield.
