Description

Technical Field

[0001] This utility model relates to the field of mechanism gear technology, and in particular to an automated detection device for mechanism gears. Background Technology

[0002] Mechanism gears are miniature gears in the core transmission system of precision machinery. They are the core components that determine the operating accuracy and lifespan of micro-mechanical systems. The precision requirements for these gears are extremely high. The tooth profile error must be controlled at the micrometer level, and there are also strict standards for surface roughness. They are one of the key indicators for measuring the manufacturing level of micro-mechanical systems and are also the core components that maintain the structural integrity of such equipment.

[0003] In the existing technology, the size of the gear parts in the mechanism is relatively small. In order to ensure the precision of subsequent assembly, personnel need to inspect the parts with a magnifying glass. However, it is easy for personnel to get tired after staring at the magnifying glass for a long time. Fluctuations in attention will lead to an increase in the error rate and make it difficult to guarantee the stability of the inspection quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automated detection device for mechanism gears.

[0005] This utility model is achieved using the following technical solution: an automated detection device for mechanism gears, comprising a housing, an array of visual inspection cameras arranged on the inner wall of the housing, a support column fixedly connected to the bottom of the inner wall of the housing, a fixed disk fixedly connected to the outer wall of the support column, an inner groove formed on the outer wall of the fixed disk, a rotating block slidably connected to the outer wall of the inner groove, a transparent rotating disk fixedly connected to the outer wall of the rotating block, a gear ring fixedly connected to the bottom of the transparent rotating disk, a gear meshing with the gear ring, a connecting rod fixedly connected to the bottom of the gear, and a motor fixedly connected to the end of the connecting rod away from the gear, the motor being fixedly connected to the bottom of the inner wall of the housing.

[0006] Through the above technical solution, the motor is fixed to the inner wall of the outer casing. When the motor runs, it drives the gear to rotate through the connecting rod. The gear meshes with the gear ring, which drives the transparent rotating disk to rotate. The transparent rotating disk slides along the outer wall of the inner groove through the rotating block, allowing the product to move on the transparent rotating disk. The support column supports the visual inspection camera array. The visual inspection camera array works with a layout of two cameras on the top and bottom and three cameras on the horizontal plane. The upper camera vertically captures the top surface of the gear, the lower camera captures the bottom surface of the gear through the transparent rotating disk, and the three cameras on the horizontal plane focus on the surface finish of the gear teeth and the gaps between the teeth, respectively. Through industrial image algorithms, edge extraction and feature comparison are performed on the images from various angles for accurate identification, thereby accurately inspecting the product, improving inspection efficiency, and ensuring the stability of inspection quality.

[0007] As a further improvement to the above solution, a cylinder is fixedly connected to the top of the fixed plate, and a connecting rod is fixedly connected to the output end of the cylinder.

[0008] As a further improvement to the above solution, a push plate is fixedly connected to one end of the connecting rod away from the cylinder, and a guide rod is fixedly connected to the outer wall of the push plate.

[0009] As a further improvement to the above solution, a fixing plate is slidably connected to the outer wall of the guide rod, and the fixing plate is fixedly connected to the top of the fixing plate.

[0010] As a further improvement to the above solution, a protrusion is fixedly connected to the bottom of the inner wall of the outer shell, a collection box is slidably connected to the outer wall of the protrusion, and a handle is fixedly connected to the outer wall of the collection box.

[0011] Through the above technical solution, the cylinder pushes the push plate through the connecting rod. The push plate is fixed to the guide rod, and the guide rod and the connecting rod slide on the inner wall of the fixed plate. The guide rod guides the movement of the push plate to ensure the stability of the push plate movement. Through the rapid movement of the push plate, defective products are pushed away from the surface of the transparent rotating disk. At this time, the defective products fall into the collection box and are collected in a unified manner, which facilitates subsequent processing, improves the continuity of the inspection process, shortens the downtime processing time, and indirectly improves the overall operating efficiency of the equipment.

[0012] As a further improvement to the above solution, a feed plate is fixedly connected to the inner wall of the outer shell, a discharge plate is fixedly connected to the inner wall of the outer shell, and a guide plate is fixedly connected to the top of the fixed plate.

[0013] As a further improvement to the above solution, an observation window is fixedly connected inside the outer casing, a controller is fixedly connected to one end of the outer casing near the observation window, and a display screen is fixedly connected to the outer wall of the outer casing.

[0014] With the above technical solution, when a qualified product comes into contact with the guide plate, it is affected by the friction of the transparent rotating disk, causing the product to slide along the guide plate. At this time, the product falls onto the discharge plate, so that it can proceed to the next process.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a motor fixed to the inner wall of the outer casing. When the motor runs, it drives the gear to rotate via a connecting rod. The gear meshes with a gear ring, which in turn drives a transparent rotating disk to rotate. The transparent rotating disk slides along the outer wall of the inner groove via a rotating block, allowing the product to move on the transparent rotating disk. A support column supports the visual inspection camera array, which operates with a layout of two cameras on the top and bottom and three cameras on the horizontal plane. The top camera vertically captures the top surface of the gear, the bottom camera captures the bottom surface of the gear through the transparent rotating disk, and the three horizontal cameras focus on the surface finish of the gear teeth and the gaps between the teeth, respectively. Industrial image algorithms are used to extract edges and compare features from images at various angles for accurate identification, thereby accurately inspecting the product, improving inspection efficiency, and ensuring the stability of inspection quality.

[0017] This invention uses a cylinder to push a push plate via a connecting rod. The push plate is fixed to a guide rod, and the guide rod and connecting rod slide on the inner wall of the fixed plate. The guide rod guides the movement of the push plate, ensuring its stability. Through the rapid movement of the push plate, defective products are pushed away from the surface of the transparent rotating disc. At this time, the defective products fall into the collection box and are collected uniformly, facilitating subsequent processing, improving the continuity of the inspection process, shortening downtime, and indirectly improving the overall operating efficiency of the equipment.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5 The automated detection device for the gear mechanism in this embodiment includes a housing 1. A visual inspection camera array 2 is provided on the inner wall of the housing 1. A support column 3 is fixedly connected to the bottom of the inner wall of the housing 1. A fixed plate 4 is fixedly connected to the outer wall of the support column 3. An inner groove 5 is opened on the outer wall of the fixed plate 4. A rotating block 6 is slidably connected to the outer wall of the inner groove 5. A transparent rotating disk 7 is fixedly connected to the outer wall of the rotating block 6. A toothed ring 8 is fixedly connected to the bottom of the transparent rotating disk 7. A gear 9 is meshed with the toothed ring 8. A connecting rod 10 is fixedly connected to the bottom of the gear 9. A motor 11 is fixedly connected to the end of the connecting rod 10 away from the gear 9. The motor 11 is fixedly connected to the bottom of the inner wall of the housing 1.

[0028] A cylinder 12 is fixedly connected to the top of the fixed plate 4, and a connecting rod 13 is fixedly connected to the output end of the cylinder 12.

[0029] A push plate 14 is fixedly connected to the end of the connecting rod 13 away from the cylinder 12, and a guide rod 15 is fixedly connected to the outer wall of the push plate 14.

[0030] A fixing plate 16 is slidably connected to the outer wall of the guide rod 15, and the fixing plate 16 is fixedly connected to the top of the fixing plate 4.

[0031] A protrusion 17 is fixedly connected to the bottom of the inner wall of the outer casing 1, a collection box 18 is slidably connected to the outer wall of the protrusion 17, and a handle 19 is fixedly connected to the outer wall of the collection box 18.

[0032] A feed plate 20 is fixedly connected to the inner wall of the outer casing 1, a discharge plate 21 is fixedly connected to the inner wall of the outer casing 1, and a guide plate 22 is fixedly connected to the top of the fixed plate 4.

[0033] An observation window 23 is fixedly connected inside the outer casing 1. A controller 24 is fixedly connected to one end of the outer casing 1 near the observation window 23. A display screen 25 is fixedly connected to the outer wall of the outer casing 1.

[0034] The implementation principle of the automated detection device for the movement gear in this embodiment is as follows: After the product enters the housing 1 through the feed plate 20, it falls onto the surface of the transparent rotating disk 7. The motor 11 is fixed to the inner wall of the housing 1. When the motor 11 runs, it drives the gear 9 to rotate through the connecting rod 10. The gear 9 meshes with the gear ring 8. At this time, the gear ring 8 drives the transparent rotating disk 7 to rotate around the support column 3. At the same time, the transparent rotating disk 7 slides along the outer wall of the inner groove 5 through the rotating block 6. The support column 3 supports the fixed disk 4, allowing the product to move on the transparent rotating disk 7. Column 3 supports the visual inspection camera array 2. The visual inspection camera array 2 operates with a layout of two cameras on the top and bottom and three cameras on the horizontal plane. The upper camera vertically captures the top surface of the gear, including planar dimensions such as the addendum circle and tooth pitch. The lower camera captures the bottom surface of the gear through the transparent rotating disk 7, detecting the flatness of the tooth root and the concentricity of the shaft hole. The three horizontal cameras focus on the tooth profile on the side of the gear, the surface finish of the tooth, and the gap between the teeth, respectively. Through industrial image algorithms, edge extraction and feature comparison are performed on the images from various angles to accurately identify micron-level defects, thereby accurately inspecting the product. Accurate detection improves detection efficiency and ensures stable detection quality. When a defective product is detected, it rotates through the transparent rotating disk 7 to the push plate 14. At this time, the cylinder 12 pushes the push plate 14 through the connecting rod 13. The push plate 14 is fixed to the guide rod 15, and the guide rod 15 and the connecting rod 13 slide on the inner wall of the fixed plate 16. The guide rod 15 guides the movement of the push plate 14, ensuring the stability of the push plate 14's movement. Through the rapid movement of the push plate 14, the defective product is pushed away from the surface of the transparent rotating disk 7 and falls into the receiving container. Inside the collection box 18, the products are collected uniformly, facilitating subsequent processing, improving the continuity of the testing process, shortening downtime, and indirectly improving the overall operating efficiency of the equipment. When the collection box 18 is full, personnel pull the collection box 18 through the handle 19, causing it to slide along the outer wall of the protrusion 17, thus removing the collection box 18. When qualified products come into contact with the guide plate 22, they are affected by the friction of the transparent rotating disk 7, causing them to slide along the guide plate 22. At this time, the products fall onto the discharge plate 21, allowing them to proceed to the next process.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
