Description

Technical Field

[0001] This invention relates to the field of measuring equipment, and more particularly to an automatic inspection device for precision parts. Background Technology

[0002] Chinese patent document (CN113624136A) discloses a parts inspection device and a calibration method for the parts inspection device. The specification states that "a parts inspection device and a calibration method for the parts inspection device. The parts inspection device includes a worktable, a movable frame, a first movable axis, a second movable axis, a contact probe, and an industrial camera; the movable frame is movably connected to the worktable, and both the first and second movable axes are movably connected to the movable frame along a first direction, which is perpendicular to the worktable; the contact probe is connected to the end of the first movable axis facing the worktable, and the industrial camera is connected to the end of the second movable axis facing the worktable. This parts inspection device can achieve efficient, rapid, and accurate measurement of different types of aerospace shell parts." However, in actual use, there are still detection gaps at the contact surface between the parts and the conveyor belt, making it difficult to ensure comprehensive inspection of the parts.

[0003] In the current parts inspection process, the conveying and inspection stages work closely together. The conveyor belt is responsible for accurately transporting parts to the inspection equipment, preparing them for subsequent inspection. However, during inspection, the side of the part that is in close contact with the conveyor belt cannot be effectively detected by the equipment. Currently, this is mainly done manually by flipping the parts to perform a comprehensive inspection of that side. If this side is not inspected, it leaves a significant inspection gap, potentially leading to product quality issues. While manual flipping offers speed advantages, it is not a perfect match for mechanized inspection processes. Firstly, an unavoidable time lag between manual operation and mechanical operation disrupts the rhythm of the entire inspection process, reducing efficiency. Secondly, the part's position is prone to shifting after manual flipping, resulting in misalignment. This change in position prevents the inspection equipment from accurately detecting according to preset parameters and locations, severely impacting the accuracy of the inspection data. Consequently, the inspection results fail to accurately reflect the part's quality, negatively affecting subsequent production and quality control.

[0004] Therefore, it is necessary to provide an automatic inspection device for precision parts to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides an automatic inspection device for precision parts, which solves the problem that existing parts inspection relies on conveyor belts to deliver parts to the bottom of the inspection device, but the surface of the parts that are in contact with the conveyor belt needs to be manually flipped for inspection, which has loopholes. Furthermore, manual flipping is difficult to perfectly match with mechanical operation, resulting in time differences, and the parts are prone to misalignment after flipping, affecting the accuracy of the inspection data.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic inspection device for precision parts, comprising: a conveying mechanism and an inspection mechanism, wherein the inspection mechanism is disposed above the conveying mechanism; The conveying mechanism includes a support frame, two connecting shells disposed above the support frame, a conveyor belt located inside the two connecting shells, two mounting components and an adjusting component located above the two connecting shells, wherein the two mounting components are respectively connected to the two adjusting components; The testing mechanism includes a mounting frame, an adjuster connected to the mounting frame, a pump connected to the adjuster, a telescopic assembly disposed below the pump, a platform assembly connected to the telescopic assembly, a transfer assembly located below the telescopic assembly, a testing assembly, and an adsorption assembly.

The detection component is used to scan and detect the surface of the part, the adsorption component is used to adsorb the part and lift the part as the pump runs, and when the pump injects air into the telescopic component, the telescopic component extends and drives the platform component and the detection component to move down.

[0007] Preferably, the upper part of the bracket is fixedly connected to two connecting shells, and the two connecting shells are connected to the same conveyor belt for transmission. The upper parts of the two connecting shells are respectively fixedly connected to the lower parts of two mounting components, and the two mounting components are respectively fixedly connected to two adjusting components.

[0011] Preferably, the telescopic assembly includes a connecting cylinder, which is connected to four branch pipes, and the bottom ends of the four branch pipes are respectively connected to four sleeves.

The bottom end of the slide rod is fixedly connected to the top of the platform assembly, the adapter assembly is fixedly connected to the bottom of the connecting cylinder, and the adapter assembly is connected to the first connecting pipe.

[0012] Because of the spring, when the pump runs in reverse to draw air from the sleeve, the spring force will prevent the slide rod from moving upward and resetting. This ensures that when the pump is running, it will prioritize drawing air from the corresponding No. 2 sealing cylinder through the No. 1 connecting pipe, No. 2 connecting pipe, connecting pipe, and No. 3 connecting pipe. This ensures that the negative pressure environment in the No. 2 sealing cylinder is formed first, guaranteeing the adsorption effect on the parts.

A reverse pump operates, drawing air from a sleeve and then from a second sealed cylinder via multiple connecting pipes. The extrusion block is pressed upwards, creating negative pressure in the second sealed cylinder due to the removal of internal air, automatically adsorbing the part. The sleeve then moves a sliding rod upwards, causing the part to rise and its bottom to be exposed. A detector comprehensively scans the bottom of the part to ensure no omissions. The connecting column and pressure plate move upwards, contacting the top plate. When the sliding rod fully resets, the pressure plate is squeezed, pushing the connecting column and extrusion block downwards, briefly separating the part and releasing the adsorption force. The part falls onto a conveyor belt and is transported away. The system automatically resets, and the pump stands ready for the next cycle. The entire process is tightly coordinated, requiring no manual intervention. All components work collaboratively, resulting in rapid response and high stability. This improves the intelligence level of the production line, reduces the need for human resources, increases inspection efficiency, and ensures the accuracy of inspection data.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 8 The precision parts automatic inspection equipment includes: a conveying mechanism 1 and an inspection mechanism 2, with the inspection mechanism 2 positioned above the conveying mechanism 1; The conveying mechanism 1 includes a support 11, two connecting shells 12 disposed above the support 11, a conveyor belt 13 located inside the two connecting shells 12, two mounting components 14 and an adjusting component 15 located above the two connecting shells 12, wherein the two mounting components 14 are respectively connected to the two adjusting components 15. The detection mechanism 2 includes a mounting frame 21, an adjuster 22 connected to the mounting frame 21, a pump 23 connected to the adjuster 22, a telescopic component 24 disposed below the pump 23, a platform component 25 connected to the telescopic component 24, a transfer component 26 located below the telescopic component 24, a detection component 27, and an adsorption component 28, wherein the detection component 27 is connected to the lower part of the platform component 25, and there are several adsorption components 28 connected through the transfer component 26. The detection component 27 is used to scan and detect the surface of the part, and the adsorption component 28 is used to adsorb the part and lift the part as the pump 23 runs. When the pump 23 injects air into the telescopic component 24, the telescopic component 24 extends and drives the platform. Component 25 and detection component 27 move downwards, reverse pump 23 operates, extracting air from sleeve 243, and then extracting air from the second sealing cylinder 282 through multiple connecting pipes. The extrusion block 289 moves upwards under pressure. The second sealing cylinder 282, due to the removal of internal air, creates negative pressure, automatically adsorbing the part. Subsequently, sleeve 243 drives slide rod 244 upwards, causing the part to rise and its bottom to be exposed. Detector 272 comprehensively scans the bottom of the part to ensure no detection omissions. Connecting column 284 and pressure plate 286 move upwards, and pressure plate 286 connects with top plate 26. When the slide bar 244 is fully reset, the pressure plate 286 is squeezed and pushes the connecting column 284 and the squeezing block 289 downward, briefly separating the parts to release the adsorption force. The parts fall onto the conveyor belt 13 and are transported away. The system automatically resets, and the pump 23 is ready to enter the next cycle. The entire process is tightly connected and requires no manual intervention. All components work together, responding quickly and with high stability. While improving the intelligence level of the production line, it reduces the demand for human resources, improves the detection efficiency, and ensures the accuracy of the detection data.

[0022] The upper part of the bracket 11 is fixedly connected to two connecting shells 12, and the two connecting shells 12 are drivenly connected to the same conveyor belt 13. The upper parts of the two connecting shells 12 are respectively fixedly connected to the lower parts of two mounting components 14, and the two mounting components 14 are respectively fixedly connected to two adjusting components 15. An adjuster 22 is fixedly connected to the front of the mounting frame 21. The adjuster 22 is fixedly connected to the pump 23 and is used for the horizontal lateral position of the pump 23. The lower part of the pump 23 is connected to the telescopic component 24, and the lower part of the telescopic component 24 is divided into... The platform component 25 and the adapter component 26 are fixedly connected. The lower part of the platform component 25 is fixedly connected to the detection component 27. The adapter component 26 is connected to several adsorption components 28. The mounting frame 21 is fixedly connected to the top of the connecting shell 12. Because it is equipped with several No. 1 sealing cylinders 281 and No. 2 sealing cylinders 282, the device can adsorb parts of different shapes. In addition, with the sealing gasket 288 outside the No. 2 sealing cylinder 282, the sealing performance during the adsorption of parts can be further ensured, which improves the versatility of the device.

[0023] Mounting assembly 14 includes a base 141, with a groove 142 on the top of the base 141. A bearing 143 is engaged in the groove 142, and a rotating shaft 144 is sleeved inside the bearing 143. A coil spring 145 is fixedly connected in the groove 142, and the other end of the coil spring 145 is fixedly connected to the rotating shaft 144. The rotating shaft 144 is fixedly connected to the adjusting assembly 15. The base 141 is fixedly connected to the top of the connecting shell 12 by a lead screw. The adjusting assembly 15 includes a baffle 151, with several mounting slots 152 on one side of the baffle 151. Each of the mounting slots 152 is engaged with a pin 154. The mounting groove 152 is rotatably connected to the roller 155 via the pin 154. The front of the baffle 151 has several arc-shaped grooves 153. One end of the baffle 151 is fixedly connected to the rotating shaft 144. The baffle 151 is located above the conveyor belt 13. Through the difference in friction between the part and the conveyor belt 13, the baffle 151, and the roller 155, as well as the blocking effect of the baffle 151, the part is automatically adjusted to the center position of the conveyor belt 13. This positioning method does not require manual intervention and can quickly and accurately position the part to the ideal position required for testing, providing a basic guarantee for the accuracy of subsequent testing.

[0024] The telescopic assembly 24 includes a connecting cylinder 241, which is connected to four branch pipes 242. The bottom ends of the four branch pipes 242 are respectively connected to four sleeves 243. Four sliding rods 244 are slidably connected inside each of the four sleeves 243. The four sleeves 243 are connected through a first connecting pipe 245. A spring is installed inside each sleeve 243. The bottom end of each sliding rod 244 is fixedly connected to the top of the platform assembly 25. A transition assembly 26 is fixedly connected to the bottom of the connecting cylinder 241 and is connected to the first connecting pipe 245. Due to the presence of springs, when… When pump 23 reverses to extract air from sleeve 243, the spring force prevents slide rod 244 from moving upwards and resetting. This ensures that pump 23 prioritizes extracting air from the corresponding second sealing cylinder 282 through connecting pipe 245, connecting pipe 265, connecting pipe 264, and connecting pipe 266. This ensures the preferential formation of a negative pressure environment within the second sealing cylinder 282, guaranteeing effective adsorption of parts. This effectively avoids problems such as weak adsorption or positioning deviations caused by asynchronous negative pressure buildup, ensuring the stability and accuracy of part position during testing. This structural design, through the synergistic effect of multi-stage connecting pipes and spring resistance, achieves precise control of the vacuuming sequence of each sealing cavity, meeting the technical requirements for repeatability and operational reliability in automated precision parts testing.

[0025] Platform component 25 includes a base plate 251, which is annular. Several elastic telescopic rods 252 are fixedly connected to the lower part of the base plate 251. A protective plate 253, which is arc-shaped, is fixedly connected to the inner wall of the base plate 251. The upper part of the base plate 251 is fixedly connected to the bottom end of a sliding rod 244. The bottom ends of the elastic telescopic rods 252 are fixedly connected to an adsorption component 28. The adapter component 26 includes an extension rod 261, with a vertical pipe 263 fixedly connected to the bottom end of the extension rod 261. The vertical pipe 263 is connected to several connecting pipes 264 and a second connecting pipe 265. The second connecting pipe 265 is connected to several third connecting pipes 266. A top plate 262 is fixedly connected to the outside of the extension rod 261. The lower part of 62 overlaps with the upper part of the adsorption component 28. The third connecting pipe 266 is connected to several adsorption components 28 respectively. The connecting pipe 264 is connected to the first connecting pipe 245. The top end of the extension rod 261 is fixedly connected to the lower part of the connecting cylinder 241. The detection device realizes comprehensive detection of the upper part, outer surface and bottom of the part through complex mechanical movement. When the pump 23 is running in the forward direction, the detector 272 and the protective cover 271 move down to detect the upper part and outer surface of the part. After the pump 23 runs in the reverse direction to draw air and move the part up, the detector 272 can scan the bottom of the part, ensuring that all surfaces of the part can be detected, avoiding detection omissions, and improving the comprehensiveness and reliability of the detection. The entire testing process, from part positioning, conveying, and testing to adsorption, release, and removal from the testing area, is fully automated, eliminating the need for frequent manual intervention. This significantly reduces labor costs and human error, while improving production efficiency and testing quality.

[0026] The detection assembly 27 includes a protective cover 271, within which several detectors 272 are fixedly connected. The detectors 272 are designed with an angle. The protective cover 271 is fixedly connected to the bottom ends of several elastic telescopic rods 252. The adsorption assembly 28 includes a first sealing cylinder 281, with a second sealing cylinder 282 fixedly connected below it. The first and second sealing cylinders 281 are in communication. The inner diameter of the first sealing cylinder 281 is larger than that of the second sealing cylinder 282. A first isolation plate 283 is fixedly connected inside the second sealing cylinder 282. A connecting post 284 is fixedly connected at the center of the first isolation plate 283. A second isolation plate 285 is fixedly connected outside the connecting post 284. The second isolation plate 285 is slidably connected inside the first sealing cylinder 281. The lower part of the second sealing cylinder 282 is fixedly connected to... The device includes a counterweight 287, a pressure plate 286 fixedly connected to the top of the connecting column 284, a sealing gasket 288 fixedly connected to the outside of the second sealing cylinder 282, and a pressing block 289 fixedly connected to the bottom of the connecting column 284. The pressing block 289 includes several support blocks. The second sealing cylinder 282 is connected to the third connecting pipe 266. Several first sealing cylinders 281 and second sealing cylinders 282 are located inside the base plate 251. The protective cover 271 not only protects the parts during the detection process and prevents external factors from interfering with the detection, but also provides a relatively closed and stable environment for the detection during the downward movement of the detector 272, reducing the influence of external light, dust and other factors on the detection results, ensuring the precision detection effect of the optical detection equipment on the parts, and further improving the accuracy of the detection.

[0027] The working principle of the automatic inspection equipment for precision parts provided by this invention is as follows: In use, the pump 23 and the detection component 27 are set in the central position by the regulator 22. Then, the part to be detected is placed above the conveyor belt 13. When the part comes into contact with the two baffles 151, the friction between the part and the conveyor belt 13 gradually becomes greater than the friction between the part and the baffles 151 and the rollers 155. As a result, the part is blocked by the baffles 151 on both sides and gradually moves to the central position of the conveyor belt 13. As the conveyor belt 13 continues to run, the part is smoothly transported to the detection area. After the part conveying and detection assembly 27 is lowered, the pump 23 is started. The pump 23 operates in the forward direction, injecting gas into the sleeve 243 along the branch pipe 242. At this time, the internal pressure of the sleeve 243 increases, squeezing the slide bar 244 downwards. This causes the slide bar 244 to move the base plate 251 downwards. Simultaneously, the detector 272 and the protective cover 271 move downwards synchronously to detect the top and outer surface of the part until the protective cover 271 is in contact with the conveyor belt. At this point, due to the continuous downward movement of the base plate 251, the spring... The telescopic rod 252 retracts, and the compression block 289 connected to the connecting column 284 adheres to the surface of the part. The second sealing cylinder 282, corresponding to the shape of the part, also adheres to the surface of the part. After being pressed to its limit, the pump 23 stops and reverses, thereby drawing air out of the sleeve 243. Simultaneously, the sleeve 243 draws air from the corresponding second sealing cylinder 282 through the first connecting pipe 245, the connecting pipe 264, the second connecting pipe 265, and the third connecting pipe 266. As the extrusion block 289 moves upward under pressure, the air inside the second sealing cylinder 282 is drawn out, which in turn attracts the part, creating a negative pressure at the point where the second sealing cylinder 282 contacts the part, thus completing the automatic adsorption of the part. Subsequently, the sleeve 243 drives the slide rod 244 to move upward, and at the same time, the part gradually moves upward, and the bottom of the part gradually appears. The detector 272 can then perform a comprehensive scan of the bottom of the part to ensure that no surface is missed. As the connecting column 284 and the pressure plate 286 move upward, the pressure plate 286 gradually comes into contact with the top plate 262. When the slide rod 244 is fully reset, the pressure plate 286 is squeezed by the top plate 262, pushing the connecting column 284 and the extrusion block 289 downward, causing the extrusion block 289 to briefly separate from the surface of the part, releasing the adsorption force. The part then falls onto the conveyor belt 13 and is then transported away from the detection area by the conveyor belt 13, completing the entire automated detection process. At this time, the system automatically resets, and the pump 23 stands by to enter the next cycle, waiting for a new part to enter and trigger a signal.

[0028] Compared with related technologies, the automatic inspection equipment for precision parts provided by the present invention has the following advantages: The detection device achieves comprehensive detection of the top, outer surface, and bottom of the part through complex mechanical movements. When the pump 23 is running in the forward direction, the detector 272 and the protective cover 271 move down to detect the top and outer surface of the part. After the pump 23 runs in the reverse direction to draw air and move the part up, the detector 272 can scan the bottom of the part, ensuring that all surfaces of the part can be detected, avoiding detection omissions, and improving the comprehensiveness and reliability of the detection. The entire testing process, from part positioning, conveying, and testing to adsorption, release, and removal from the testing area, is fully automated, eliminating the need for frequent manual intervention. This significantly reduces labor costs and human error, while improving production efficiency and testing quality.
