Description

Technical Field

[0001] This utility model relates to the field of workpiece visual inspection technology, and in particular to a visual inspection alignment mechanism. Background Technology

[0002] Visual inspection uses machines to replace human eyes for measurement and judgment. It involves machine vision products converting the captured target into image signals, transmitting them to a dedicated image processing system, and then converting them into digital signals based on pixel distribution, brightness, color, and other information. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. It is a valuable mechanism for production, assembly, or packaging. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers. When visual inspection continuously inspects multiple products, a positioning mechanism is required to locate the inspection unit.

[0003] In existing devices, most cameras are fixed in place. Different types of cameras may be needed for different application scenarios, such as low light or high light environments. The difficulty in replacing cameras makes it impossible for the visual inspection mechanism to adapt to different environmental conditions. At the same time, cameras may malfunction or degrade in performance after long-term use, resulting in errors in the detection effect. Therefore, a visual inspection alignment mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a visual inspection alignment mechanism that solves the problems mentioned in the background art. In the existing devices, most cameras are in a fixed state when in use. Different types of cameras may be needed for different application scenarios, such as low light or high light environments. The cameras are difficult to replace, which makes the visual inspection mechanism unable to adapt to different environmental conditions. At the same time, the cameras may malfunction or degrade in performance after long-term use, resulting in errors in the detection effect.

[0014] (III) Beneficial Effects

[0015] This utility model provides a visual inspection alignment mechanism, which has the following beneficial effects:

[0016] 1. This visual inspection alignment mechanism, through the setting of the snap-fit ​​component, allows for camera replacement when the pull plate is pulled during use. The movement of the pull plate causes the connecting spring to be in a stretched state, and the plug rod moves out from the inside of the connecting block. This allows for the replacement of cameras with different parameters according to different inspection tasks. The camera parameters can be adjusted and optimized in the laboratory or other environments to meet specific inspection needs. At the same time, after prolonged use, the camera may malfunction or experience performance degradation, such as lens wear or sensor aging. In this case, the camera can be disassembled for repair or replacement to ensure the normal operation of the visual inspection system.

[0017] 2. This visual inspection alignment mechanism, through the setting of the clamping component, places the workpiece to be inspected on the placement plate during inspection, activates the hydraulic rod, and drives the moving plate to move. When the moving plate moves, the protective soft plate clamps the workpiece to be inspected, which can protect the workpiece to be inspected, thereby firmly fixing the workpiece to be inspected in a specific position, reducing the inspection error caused by the uncertainty or movement of the workpiece position, and improving the reliability and accuracy of the inspection results.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a visual inspection alignment mechanism, including a worktable 1, a placement plate 2 slidably connected to the top surface of the worktable 1, and two sets of clamping components 3 fixedly connected to the outer side of the placement plate 2. The clamping components 3 clamp the workpiece to be inspected, preventing it from moving during the inspection process. A connecting rod 4 is fixedly connected to the top surface of the worktable 1, and a lifting hydraulic rod 5 is slidably connected inside the connecting rod 4. One end of the lifting hydraulic rod 5 is fixedly connected to a mounting frame 6, and two sets of snap-fit ​​components 7 are fixedly connected to the outer side of the mounting frame 6. The system is configured to allow for the replacement of camera 14 according to different detection tasks. Both sets of clamping assemblies 3 include two sets of pushing hydraulic rods 301 fixedly connected to the outside of the placement plate 2. One end of each set of pushing hydraulic rods 301 is fixedly connected to a moving plate 302, and one side of each set of moving plates 302 is fixedly connected to a protective soft plate 303. Both sets of snap-fit ​​assemblies 7 include connecting springs 701 fixedly connected to the outside of the mounting frame 6. The inside of each set of connecting springs 701 is fitted with a plug rod 702, and one end of each set of connecting springs 701 is fixedly connected to a pull plate 703.

[0025] The surface of the workbench 1 is provided with two sets of sliding grooves, and the placement plate 2 is slidably connected to the inside of the sliding grooves. The placement plate 2 serves to place the workpiece to be inspected.

[0026] One set of slides has a fixed connection of a limiting rod 8 inside, and the other set of slides has a threaded rod 9 inside. The limiting rod 8 serves to limit the placement plate 2.

[0027] A motor housing 10 is fixedly connected to one side of the workbench 1. A servo motor is installed inside the motor housing 10. The servo motor drives the threaded rod 9 to rotate.

[0028] The workbench 1 is connected to a mounting plate 11 by bolts. The top surface of the mounting plate 11 is fixedly connected to a display 12. The display 12 is used to display the images captured by the camera 14.

[0029] A connecting block 13 is inserted and connected to the bottom surface of the mounting frame 6. One end of the connecting block 13 is fixedly connected to the camera 14. The connecting block 13 serves to install the camera 14.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, pull the pull plate 703. The movement of the pull plate 703 causes the connecting spring 701 to be in a stretched state, and the plug rod 702 moves out from the inside of the connecting block 13, so that the camera 14 can be replaced. This allows the camera with different parameters to be replaced according to different detection tasks. The parameters of the camera can be adjusted and optimized in the laboratory or other environments to meet specific detection needs.

[0033] The second step: During the inspection, the workpiece to be inspected is placed on the placement plate 2, and the hydraulic rod 301 is activated. The hydraulic rod 301 drives the moving plate 302 to move. When the moving plate 302 moves, the protective soft plate 303 clamps the workpiece to be inspected. The protective soft plate 303 can protect the workpiece to be inspected, thereby firmly fixing the workpiece to be inspected in a specific position, reducing the inspection error caused by the uncertainty or movement of the workpiece position, and improving the reliability and accuracy of the inspection results.
