[0019] Reference Figures 1 to 3 According to the present invention, a hardware cleaning device includes a cleaning device, a drying device, and a visual inspection device 17 connected in sequence by a mesh conveyor belt 1. The cleaning device includes a primary spray section 2 for spraying clean water, a secondary spray section 3 for spraying cleaning solvent, and a tertiary spray section 4 for spraying clean water, connected in sequence. The primary spray section 2, the secondary spray section 3, and the tertiary spray section 4 are respectively connected to a first liquid storage tank 7, a second liquid storage tank 8, and a third liquid storage tank 9 through pipes equipped with a water pump 5 and a one-way valve 6. The bottom of the primary spray section 2, the secondary spray section 3, and the tertiary spray section 4 are respectively equipped with a first water receiving tray 10, a second water receiving tray 11, and a third water receiving tray 12. The first water receiving tray 10 and the third water receiving tray 12 are both connected to a first recovery tank 13 through pipes equipped with a water pump 5 and a one-way valve 6. The second water receiving tray 11 is connected to a second recovery tank 14 through pipes equipped with a water pump 5 and a one-way valve 6.

[0020] It is understood that the hardware cleaning equipment provided in this embodiment of the present invention, through a three-stage spray process of "clean water - cleaning solvent - clean water", first uses clean water for preliminary rinsing, then uses a special cleaning solvent to deeply remove oil and impurities, and finally uses clean water to rinse away residual solvent, ensuring thorough cleaning of the hardware surface and significantly improving cleaning quality. The first and third spray stages 4 use clean water, and the returned liquid is collected through water trays and then uniformly enters the first recovery tank 13, achieving centralized recovery and recycling of clean water. The second spray stage 3 uses cleaning solvent, and its waste liquid is recovered through an independent second water tray 11 and second recovery tank 14, avoiding pollution caused by cleaning solvent mixing into the clean water system. Each spray stage is equipped with a water pump 5 and a one-way valve 6 to ensure directional liquid flow, prevent backflow and cross-contamination, improve the utilization rate of water resources and cleaning agents, and reduce operating costs. The cleaning device, drying device, and appearance inspection device 17 are connected sequentially by a mesh conveyor belt 1, realizing fully automatic continuous operation of the workpiece from cleaning to drying to quality inspection, reducing manual intervention and improving production efficiency. In summary, the embodiments of this utility model achieve high efficiency, cleanliness, and automation in the cleaning process of hardware products, and have good application prospects and economic benefits.

[0021] Furthermore, refer to Figure 1 According to some embodiments of the present invention, the drying device includes an air-drying section 15 and a drying section 16 connected in sequence.

[0022] Specifically, this embodiment of the invention incorporates a wind-drying section 15 and a drying section 16. First, airflow is used to quickly remove surface moisture, followed by heating to further evaporate residual moisture, ensuring the hardware products are completely dry. This gradual drying process is gentle, reducing the risk of deformation or damage to the hardware products that might be caused by rapid, high-temperature drying, making it particularly suitable for precision parts. Different materials of hardware products have varying drying requirements; the segmented drying design better adapts to the characteristics of various materials, expanding the equipment's applicability.

[0023] Furthermore, refer to Figure 2 According to some embodiments of the present invention, the appearance inspection device 17 includes a housing 171 disposed on the mesh conveyor belt 1 and a vision inspection component installed inside the housing 171.

[0024] Understandably, housing 171 provides a relatively enclosed and stable environment for visual inspection, reducing the impact of external factors (such as changes in light) on the inspection results. The visual inspection components housed within housing 171 ensure that the camera and other inspection elements are in optimal working condition, thereby improving inspection accuracy and reliability. Integrating the visual inspection components into the production equipment automates the process of directly performing quality inspection after cleaning, thus improving production efficiency.

[0025] Furthermore, refer to Figure 2 According to some embodiments of the present invention, the visual inspection component includes a first camera 172 located directly above and facing the mesh conveyor belt 1, and two second cameras 173 located on both sides of the mesh conveyor belt 1 and facing the mesh conveyor belt 1.

[0026] It is understood that by positioning the first camera 172 directly above the conveyor belt 1, while two second cameras 173 capture images from both sides, this embodiment of the invention ensures comprehensive, all-around image acquisition of the hardware products, improving the comprehensiveness of defect detection. The multi-angle camera configuration allows for more precise location and identification of minute flaws or damage on the surface of the hardware products, enhancing detection capabilities. Furthermore, for irregularly shaped hardware products, multi-view imaging helps capture all details, ensuring quality control for different types of products.

[0027] Furthermore, refer to Figure 2 According to some embodiments of the present invention, the second camera 173 is rotatably connected to the housing 171.

[0028] Understandably, the rotatable second camera 173 can adjust its viewing angle as needed to accommodate hardware products of different sizes and shapes, increasing the flexibility of the equipment. Dynamically adjusting the camera angle according to actual inspection requirements allows for the acquisition of clearer and more valuable image information, improving inspection accuracy.

[0029] Furthermore, refer to Figure 3 According to some embodiments of the present invention, the appearance inspection device 17 further includes two guide bars 174 disposed on the mesh conveyor belt 1 and located at the entrance of the housing 171. The two guide bars 174 gradually move closer together along the conveying direction of the mesh conveyor belt 1 to allow individual hardware products to pass through.

[0030] Understandably, the design of guide bar 174 allows each hardware product to pass through the vision inspection area independently, avoiding inspection chaos or misjudgment caused by multiple products entering simultaneously. The orderly product flow improves inspection efficiency, enabling the vision system to process each product more efficiently and accelerating the overall production pace. Simultaneously, guide bar 174 helps products to be neatly arranged, reducing potential product collisions during transport and lowering the defect rate.

[0031] Furthermore, refer to Figure 3According to some embodiments of the present invention, the appearance inspection device 17 further includes a defective product recycling mechanism located at the outlet of the housing 171. The defective product recycling mechanism includes a defective product conveyor belt 175 located on one side of the mesh conveyor belt 1 and a push plate 176 located on the other side of the mesh conveyor belt 1. The push plate 176 is connected to a drive structure 177 to move closer to or further away from the defective product conveyor belt 175.

[0032] Understandably, when a single hardware product passes through the vision inspection area, based on the inspection results of the vision inspection component, once a defective product is detected, the drive structure 177 drives the push plate 176 to immediately push the defective product output from the housing 171 to the defective product conveyor belt 175, achieving immediate separation and preventing the mixing of defective and qualified products. This automated defective product recycling mechanism reduces manual intervention, speeds up the processing of non-conforming products, and maintains smooth production line operation. It should be noted that the drive structure 177 can be a cylinder, hydraulic cylinder, lead screw motor, etc., and is not specifically limited here.

[0033] Furthermore, refer to Figure 2 According to some embodiments of the present invention, the visual inspection component also includes a supplementary light 178 disposed inside the housing 171 and an alarm 179 disposed outside the housing 171.

[0034] Understandably, the supplementary light 178 provides ample illumination, ensuring clear, high-contrast images under any conditions and improving inspection accuracy. When a defective product is detected, the alarm 179 will sound an alarm, promptly notifying operators to take swift action. The alarm 179 can also be used to indicate equipment malfunctions or other abnormalities, enhancing the safety and stability of the entire system.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
