Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to an online adjustment method for machine vision inspection of printing pressure. Background Technology

[0002] Visual inspection uses machines to replace human eyes for measurement and judgment. It involves using machine vision products (image acquisition devices, either CMOS or CCD) to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, these signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the equipment's actions based on the judgment results. It is a valuable mechanism for production, assembly, or packaging. Visual inspection typically uses cameras to observe objects, and the observed information is provided to the control system for analysis. However, existing visual inspection cameras have fixed angles and limited observation ranges. Therefore, we propose an online adjustment method for machine vision inspection of printing pressure. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing vision inspection cameras, which have fixed angles and limited observation ranges, by proposing an online adjustment method for machine vision inspection of printing pressure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an online adjustment method for machine vision inspection of printing pressure, including a slotted plate and a camera. The slotted plate has a slot on one side, and an upper plate is set directly above the slotted plate. The camera is set directly below the upper plate, and a cover plate is fitted above the camera. Connecting mechanisms are provided between the camera and both sides of the cover plate. An upper rotating rod is rotatably connected to the upper part of the cover plate. One end of the upper rotating rod passes through the slotted plate and is rotatably connected to the lower part of the upper plate. An adjustment mechanism is provided between one side of the cover plate and the upper plate.

[0006] As a preferred technical solution, a base plate is fixed on both sides below the groove plate, and mounting holes are opened on both sides of the two base plates.

[0007] As a preferred technical solution, the connection mechanism includes a slot and a plate. The slot is opened on both sides of the cover plate, the plate is fixed on both sides of the camera and inserted into the slot, and a limiting mechanism is provided between the plate and the cover plate.

[0008] As a preferred technical solution, the limiting mechanism includes a sleeve and a limiting hole. The limiting hole is opened on the insert plate, the sleeve is fixed to one side of the cover plate, and a limiting rod is provided inside the sleeve. One end of the limiting rod passes through the sleeve and the limiting hole and extends outward, and the other end of the limiting rod passes through the sleeve and extends outward. A spring is sleeved on the outside of each limiting rod. One end of the spring is fixed to the limiting rod, and the other end of the spring is fixed to the inner wall of the sleeve. A pull rod is fixed between the two limiting rods.

[0009] As a preferred technical solution, the adjustment mechanism includes a rotating rod and a sliding hole. The sliding hole is opened on one side of the upper plate, and bearings are fixed on both sides of the sliding hole. A sliding plate is slidably arranged in the sliding hole. A threaded rod is connected in one of the bearings. One end of the threaded rod passes through the sliding plate and the other bearing and is connected to a motor. The motor is fixedly installed on the side wall of the upper plate. One end of the rotating rod is rotatably connected to the side wall of the cover plate, and the other end of the rotating rod passes through the plate groove and is rotatably connected to the bottom of the sliding plate.

[0010] As a preferred technical solution, arc-shaped sliding grooves are provided on both sides of the upper plate, side plates are fixed on both sides of the upper plate, an arc-shaped sliding plate is fixed on one side below the side plate, and the arc-shaped sliding plate is slidably disposed in the arc-shaped sliding groove. A connecting plate is fixed on one side above the side plate, a side connecting plate is fixed on one side above the groove plate, and an electric telescopic rod is fixed on one side of the side connecting plate. One end of the electric telescopic rod is movably connected to the connecting plate.

[0011] As a preferred technical solution, a groove is provided below the arc-shaped sliding plate, and a ball bearing is movably connected in the groove.

[0012] As a preferred technical solution, the adjustment steps include:

[0013] S: By installing the slot plate on the printing press and then installing the camera inside the cover plate, when it is necessary to adjust the vertical angle of the camera, simply start the motor. Starting the motor will drive the slide plate to slide on the threaded rod. The sliding of the slide plate will drive the rotating rod to rotate, thereby adjusting the vertical angle of the camera.

[0014] S: When it is necessary to adjust the left and right angle of the camera, simply activate the electric telescopic rod. The electric telescopic rod will drive the curved slide plate to slide within the curved groove, thereby adjusting the left and right angle of the camera.

[0015] The present invention proposes an online adjustment method for visual inspection of printing pressure machines. The beneficial effects are as follows: When using this visual inspection, it is only necessary to install the slot plate on the printing pressure machine. When it is necessary to adjust the vertical angle of the camera, it is only necessary to start the motor. Starting the motor can drive the slide plate to slide on the threaded rod. The sliding of the slide plate can drive the rotating rod to rotate, thereby adjusting the vertical angle of the camera, thus effectively increasing the observation range of the camera.
