Description

Technical Field

[0001] This invention relates to the field of garden knife testing equipment, and in particular to a visual inspection device for blade defects in garden knives. Background Technology

[0002] Garden knives are commonly used tools in gardening operations. The sharpness and integrity of their blades directly determine cutting efficiency and safety. Blade defects can seriously affect work results and even cause safety hazards. Therefore, blade defect detection is a key link in ensuring product quality during the production process of garden knives. With the increasing demand for large-scale and standardized production in the garden tool industry, automated visual inspection technology, due to its high inspection efficiency and objectivity, is gradually replacing traditional manual visual inspection and becoming the mainstream trend. Existing visual inspection devices for garden knife edge defects have shortcomings. First, their adaptability is poor. When dealing with garden knives of different lengths, widths, and thicknesses, manual disassembly or adjustment of the clamping and positioning components is required, which is cumbersome and time-consuming, severely reducing inspection efficiency. Furthermore, component installation misalignment can lead to insecure knife fixation, causing slight displacement during inspection and affecting accuracy. Second, automation is insufficient. Loading and unloading rely heavily on manual assistance, resulting in high labor intensity and potential disruptions in the inspection process due to inconsistent human operation rhythms. Third, the inspection environment is poorly controlled, lacking effective light-shielding and supplementary lighting structures. External light interference can easily cause blurred images from the inspection camera, and the single inspection angle makes it difficult to fully cover the knife edge and surface, easily leading to missed detection of minor defects. Therefore, improvements are needed to address these issues. Summary of the Invention

[0019] Working principle: In this embodiment, the present invention also proposes a method for using a visual inspection device for defects in the blade of garden knives, including the following steps: Step 1: First, connect all electrical equipment to the device and power it on to complete the power supply preparation before testing. According to the length specifications of the garden knife to be tested, adjust the moving plate 9 on the top plate 8 of the rotating table 4. After the lower end of the moving plate 9 slides along the T-shaped slide groove to the appropriate position, the moving plate 9 is fixed firmly by the positioning bolt and the anti-slip strip 10 in the positioning groove to ensure the subsequent clamping compatibility. Start the third motor 29 inside the workbench 1. The third motor 29 drives the drive wheel 28 to rotate. The drive wheel 28 drives the driven wheel 27 of the front first support frame 23 and the second support frame 25 to rotate synchronously through the first chain belt 30. At the same time, through the transmission cooperation of the second chain belt 31 and the connecting wheel 32, it drives the driven wheel 27 of the two rear second support frames 25 to rotate, thereby controlling the first conveyor belt 24 and each second conveyor belt 26 to start running, preparing for the transfer of the knife loading and unloading. Step two: Place the tool to be inspected on the first conveyor belt 24 at the front end. The conveyor belt transports the tool to the designated clamping station. Activate the third electric push rod 33 in the tool clamping assembly. The third electric push rod 33 pushes the housing 34 and the upper structure to rise and fall, adjusting the initial height of the adsorption head 49 and the tool. Simultaneously, activate the fourth motor 35 inside the housing 34. The fourth motor 35 drives the adjusting seat 36 to rotate. In conjunction with the fifth motor 37 on the adjusting seat 36, drive the lead screw 38 to rotate. The moving block 40 slides along the guide rod 39 in the sliding groove, adjusting the horizontal position of the adsorption head 49. Use the positioning camera 43 on one side of the connecting housing 41 to photograph the tool to be clamped, identify and feedback the tool coordinate information to avoid positional deviation. Activate the sixth motor 42 to drive the rotating seat 44 to rotate. The seventh motor 45 drives the worm gear 46 and worm wheel 47 to mesh and drive the connecting seat 48 and the adsorption head 49 to adjust to the appropriate angle. The adsorption head 49 is connected to an external air pump to generate negative pressure, accurately adsorbing the tool to be inspected. Then, through the coordinated action of the above components, the tool is transferred to the top of the carrier plate 8 on the rotating table 4. Step 3: After the tool is transferred to the designated position on the carrier plate 8, the first electric push rod 11 on the top surface of the moving plate 9 is activated. The first electric push rod 11 pushes the moving seat 12 to move towards the tool, so that the rotating seat 16 fits against both sides of the tool. The second motor 13 inside the moving seat 12 is activated. The second motor 13 drives the second drive bevel gear 14 to rotate. The second drive bevel gear 14 meshes with the second driven bevel gear 15 to drive the rotating seat 16, which has an L-shaped cross-section, to rotate. The clamping plates 17 on both sides of the rotating seat 16 cooperate with the inner rubber plate 18 to firmly clamp the tool from both sides, preventing displacement due to vibration or rotation during the detection process. The first motor 7 inside the worktable 1 is activated. The first motor 7 drives the first drive bevel gear 6 to rotate. The first drive bevel gear 6 meshes with the first driven bevel gear 5 to drive the rotating table 4 to rotate smoothly through the rotating shaft, accurately transferring the clamping and positioning assembly with the clamped and positioned tool to the closed detection area enclosed by the light shield 2. Step 4: After the tool arrives at the inspection station, activate the second electric push rod 19 on the top surface of the light shield 2. The second electric push rod 19 pushes the T-shaped connecting plate 20 up and down, adjusting the distance between the supplementary lights 21 at the three ends of the bottom surface of the connecting plate 20 and the tool to adapt to the inspection requirements of tools of different thicknesses. Turn on the supplementary lights 21 to provide uniform and sufficient auxiliary light to the inspection area, eliminate the shadow of the tool edge, and avoid interference from external light. At the same time, activate the three inspection cameras 22 on the top surface of the light shield 2. The inspection cameras 22 are aligned with the tool through the inspection port on the top surface of the connecting plate 20 to capture images of the tool edge and blade surface, capturing defect information such as notches, chipping, and burrs. During the inspection process, the second motor 13 can be activated again. Through the transmission of the second drive bevel gear 14 and the second driven bevel gear 15, the rotation angle of the rotating seat 16 and the tool is adjusted to achieve all-round inspection of the front and back blade surfaces and the cutting edge, completely avoiding blind spots. If continuous inspection is required, the rotating table 4 will continue to rotate, transferring the next clamped tool to the inspection area and repeating the above inspection actions. Step 5: After the tool inspection is completed, the tool status is determined based on the image data collected by the inspection camera 22. If a defect is detected, the tool clamping component restarts the suction head 49 according to the defect type, removes the defective tool, and places it on the corresponding second conveyor belt 26 on the other side of the front and rear ends. If the tool is intact, it is transferred by the tool clamping component to the second conveyor belt 26 on the rear end side. Each conveyor belt continues to operate, conveying intact tools and tools with different types of defects out of the device to complete the sorting and unloading. After all the tools to be inspected have been inspected and unloaded, the power supply of all electrical equipment in the device is turned off, the wire connections are disconnected, and all components of the device are reset to complete the visual inspection of the defects of the garden tool blades.
