[0002] With manufacturing costs rising and market competition intensifying, reducing production costs and improving industrial production are crucial challenges. Automatic aperture measurement technology is widely used in the automotive, aerospace, electronics, and machinery industries to measure the aperture dimensions of various components, ensuring product quality and production efficiency.

[0003] On the production line, automatic aperture measurement technology can be used to monitor the aperture size of products in real time, automatically and accurately measuring the aperture size. This allows for the timely detection of quality problems and the implementation of corrective measures to ensure that product quality meets standards.

[0004] In the existing technology, contact sensors are usually used for measurement. Contact measurement has the risk of scratching the surface of the inner diameter being measured, and scratches on the inner diameter surface are not easy to detect, which may lead to defective products being released. Utility Model Content

[0005] This utility model provides an integrated automatic aperture measurement and sorting system, which uses a non-contact measuring instrument to measure aperture size, ensuring measurement accuracy and effectively preventing scratches on the inner aperture.

[0006] An integrated automatic aperture measurement and sorting system includes a feeding assembly, a robotic arm assembly, an aperture measurement assembly, a discharging assembly, and a waste recycling assembly. The feeding assembly, aperture measurement assembly, discharging assembly, and waste recycling assembly are arranged around the robotic arm assembly. A part to be measured with an aperture is placed on the feeding assembly. The robotic arm assembly can extract the part and move it, placing it on the worktable of the aperture measurement assembly. The aperture measurement assembly includes a support, with a worktable on its upper surface. A first limiting part is provided at one end of the worktable, and a push block is provided on the opposite side of the limiting part. The push block is connected to a cylinder. A second limiting part and a third limiting part are provided on both sides of the worktable, arranged opposite to each other. Both the second and third limiting parts include a limiting rod. The end of each limiting rod includes a flat surface and an arcuate surface, with the arcuate surface located near the push block. A through hole matching the part is provided on the side of the worktable near the first limiting part. A pneumatic gauge is provided below the worktable, and the detection head of the pneumatic gauge can pass through the through hole into the aperture of the part.

[0007] Furthermore, the second and third limiting parts also include an adjusting rod, which is threadedly connected to the limiting rod, and rotating the adjusting rod controls the length of the extending adjusting rod.

[0008] Furthermore, the workbench is provided with upper and lower modules and guide rails below. The upper and lower modules can move up and down along the guide rails. The upper surface of the upper and lower modules is provided with connecting parts, and the pneumatic measuring instrument is installed on the upper surface of the connecting parts.

[0009] Furthermore, the connector is provided with a first adjusting nut and a second adjusting nut.

[0010] Furthermore, the feeding assembly includes a first frame, on which a first conveyor belt for transporting parts is provided, and at one end of the first conveyor belt is a part presence or absence detection sensor, and the feeding assembly is connected to the production line.

[0011] Furthermore, the waste recycling component is a recycling bin.

[0012] Furthermore, the discharge assembly includes a second frame on which a second conveyor belt for transporting parts is mounted, and the discharge assembly is connected to the packaging line.

[0013] The technical solution of this utility model has the following technical effects:

[0014] Because the pneumatic measuring instrument is driven by upper and lower modules for testing, the measuring head of the pneumatic measuring instrument does not directly contact the parts, thus effectively avoiding scratches on the inner wall of the aperture and preventing defective products from flowing out. The feeding assembly, aperture measuring assembly, discharging assembly, and waste recycling assembly are arranged around the robotic arm assembly, allowing measurement and sorting functions to be achieved through a single robotic arm assembly, reducing costs.

[0015] The ends of the second and third limiting parts of the aperture measuring assembly include a flat surface and an arc surface. As the pusher pushes the part to move, the arc surface has a certain guiding effect on the part, so that the part can effectively enter the range defined by the second and third limiting parts.

[0016] By setting adjustment rods in the second and third limiting parts, the spacing can be adjusted to accommodate the testing of parts of various sizes. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] An integrated automatic aperture measurement and sorting system includes a feeding assembly 2, a robotic arm assembly 3, an aperture measurement assembly 1, an discharge assembly 4, and a waste recycling assembly 5. The feeding assembly 2, aperture measurement assembly 1, discharge assembly 4, and waste recycling assembly 5 are arranged around the robotic arm assembly 3. The feeding assembly 2 includes a first frame 21 with a first conveyor belt 22 for transporting parts. One end of the first conveyor belt 22 is equipped with a part presence / absence detection sensor 23. The feeding assembly 2 is connected to a production line. A part 9 with an aperture to be measured can be transported on the first conveyor belt to the side of the part presence / absence detection sensor 23. The robotic arm assembly can pick up the part 9, move it, and place it on the aperture measurement assembly 2. The measured part can then be transported to the discharge assembly 4 or the waste recycling assembly 5. The discharge assembly 4 includes a second frame 41 with a second conveyor belt 42 for transporting parts. The discharge assembly 4 is connected to a packaging line.

[0023] The aperture measuring assembly includes a bracket 11. The upper surface of the bracket 11 is provided with a worktable 12 for placing the part 9. One end of the worktable 12 is provided with a first limiting part 13. On the opposite side of the limiting part 13, there is a push block 14. The push block 14 is connected to a cylinder 17. When the cylinder 17 is working, it can drive the push block 14 to reciprocate on the worktable 12 through a transmission mechanism. The movement of the push block 14 can drive the part 9 to move toward the limiting part 13.

[0024] The workbench 12 has a second limiting part 15 and a third limiting part 16 arranged opposite to each other on both sides. The second limiting part 15 and the third limiting part 16 have the same structure and are arranged opposite to each other. The second limiting part 15 includes an adjusting rod 151 and a limiting rod 152. The push block 14 pushes the part to move to the range defined by the first limiting part 13, the second limiting part 15 and the second limiting part 16. The push block 14 pushes the part 19 tightly and fixes it between the first limiting part and the push block 14.

[0025] The workbench 12 has a through hole 121, which corresponds to the hole in the part 9. Below the workbench 12 are upper and lower modules 18 and a guide rail 182. The upper and lower modules 18 can move up and down along the guide rail 182. The upper and lower modules 18 include a drive source 184, a drive rod 183, and a moving component 185. A connector 181 is provided on the upper surface of the moving component 185, and a pneumatic gauge 19 is provided on the upper surface of the connector. The pneumatic gauge 19 can be selected from existing technologies, and its detection head 191 corresponds to the hole in the part. The drive source 184 drives the moving component 185 to move along the guide rail 182 via the drive rod 183. When the moving component 185 drives the pneumatic gauge 19 upward via the connector 181, the detection head extends into the hole in the part and measures the hole diameter. If the measured value of the part is within the threshold range, the part is considered qualified, and the part is extracted and placed into the discharge component 4. If the side wheel value of the part exceeds the threshold, the part is considered unqualified. The upper and lower modules 18 drive the pneumatic measuring instrument 19 downwards to prepare for the next measurement. The robotic arm assembly extracts the part and places it into the waste recycling assembly 5. In this embodiment, the discharge assembly 4 is a production line connected to the packaging line, and the part can automatically enter the packaging line through the discharge assembly 4. The waste recycling assembly 5 is a recycling bin. It can be understood that the waste recycling assembly 5 can also be set as a waste recycling production line.

[0026] Because the pneumatic measuring instrument is driven by upper and lower modules for testing, the measuring head of the pneumatic measuring instrument does not directly contact the parts, thus effectively avoiding scratches on the inner wall of the aperture and preventing defective products from flowing out. The feeding assembly, aperture measuring assembly, discharging assembly, and waste recycling assembly are arranged around the robotic arm assembly, allowing measurement and sorting functions to be achieved through a single robotic arm assembly, reducing costs.

[0027] The adjusting rod 151 and the limiting rod 152 are connected by a thread. Rotating the adjusting rod adjusts the extension length of the limiting rod 152. Adjusting rods are provided at the second and third limiting parts. The connecting member 181 is equipped with a first adjusting nut and a second adjusting nut (not shown). The first adjusting nut adjusts the forward and backward movement of the connecting member 181 relative to the moving assembly 185, and the second adjusting nut adjusts the left and right movement of the connecting member 181 relative to the moving assembly 185. Through the cooperation of the adjusting rod, the limiting rod, and the first and second adjusting nuts, the measuring device can be used to test parts of various sizes, thus broadening its application range.

[0028] The end of the adjusting rod 152 includes a flat portion 1521 and an arc-shaped portion 1522, with the arc-shaped portion 1522 positioned near the push block 14. By providing the flat portion 1521 and the arc-shaped portion 1522, the arc-shaped portion provides a guiding effect on the part during the push block's movement, while the flat portion 1521 effectively limits the part after it enters the space, thus ensuring that the part effectively enters the range defined by the second and third limiting portions.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
