Description

Technical Field

[0001] The present invention relates to the technical field of production quality inspection, in particular to a quality inspection mechanism for the production of mechanical parts. Background Art

[0002] After parts are produced, their surfaces need to be inspected for quality. An optical detector is a device that uses optical imaging technology to automatically detect, identify, and analyze surface or internal defects in products. It captures light signals reflected, transmitted, or scattered by the surface of the object being tested, and uses image processing technology to analyze these signals to determine whether the product meets quality standards.

[0003] When some existing optical inspection instruments scan and inspect parts, they need to be manually flipped over after scanning one side. Manually flipping parts takes extra time and effort, especially when processing a large number of parts. This repetitive work will significantly increase the inspection cycle.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 3 , the present invention provides a technical solution: a quality inspection mechanism for the production of mechanical parts, comprising an optical inspection device 1, a detection mechanism 2 is provided on the top of the optical inspection device 1; The detection mechanism 2 includes a flip unit 21 . The flip unit 21 is disposed on the top of the optical detection device 1 . The flip unit 21 is used to flip the part.

[0023] As a further limitation of the detection mechanism 2 of the present invention, the flip unit 21 includes a guide frame 2101, a threaded groove 2102 is provided inside the guide frame 2101, and a movable groove 2103 is provided on the inner wall of the threaded groove 2102. There are four movable grooves 2103, and one side of the four movable grooves 2103 is fixedly connected to a rack 2104. The top of the optical detection device 1 is fixedly connected to a motor 2105, and the output end of the motor 2105 is fixedly connected to a transmission plate 2107. The bottom of the transmission plate 2107 contacts the top of the guide frame 2101, and the bottom of the transmission plate 2107 is fixedly connected to a sliding telescopic rod 2108. The telescopic end of the sliding telescopic rod 2108 is fixedly connected to an L-shaped rod 2109. The inner wall of the threaded groove 2102 is slidably connected to a rotating rod 2106, and one end of the rotating rod 2106 is fixed to the L-shaped rod 2109. One end is rotatably connected, and the surface of the rotating rod 2106 is fixedly connected to the ring gear 2110, and the surface of the ring gear 2110 is meshed with the surface of the rack 2104. The surface of the rotating rod 2106 is fixedly connected to the hexagonal block 2111, and the hexagonal block 2111 is used in conjunction with the threaded groove 2102 and the movable groove 2103. The surface of the rotating rod 2106 is fixedly connected to the first pulley 2113. By setting the flipping unit 21, the optical inspection device 1 can quickly inspect multiple surfaces of the part without frequently removing the part from the workbench and manually flipping it multiple times, avoiding the occurrence of problems such as incomplete flipping and inaccurate flipping angle. Compared with the traditional manual flipping method, this not only reduces manual intervention, thereby shortening the overall inspection cycle, but also improves inspection efficiency and accuracy, reduces the occurrence of human errors, and improves work efficiency.

[0024] refer to Figure 3 One end of the rotating rod 2106 is fixedly connected to the limiting plate 2112, and one side of the limiting plate 2112 contacts the inner wall of the guide frame 2101. By setting the limiting plate 2112, the rotating rod 2106 can be limited by contacting the inner wall of the guide frame 2101, thereby preventing the rotating rod 2106 from disengaging from the thread groove 2102 during movement, thereby ensuring the stability of the rotating rod 2106 during movement.

[0025] The specific implementation of this embodiment is as follows: the detection lens of the optical detection device 1 utilizes optical phenomena such as light propagation, scattering, reflection, refraction, interference, and diffraction, and performs all-round detection of the object to be detected through a precise optical system and image processing technology. These optical phenomena are accurately controlled and measured in the detector, thereby obtaining information such as the shape, size, surface roughness, and defects of the object to be detected. The initial position of the transmission plate 2107 is at the bottom of the detection lens, and the rotating rod 2106 is also located at the first layer of the thread groove 2102. After the user fixes the part, the detection lens will detect the top of the part. After the detection is completed, the motor 2105 is started by the external control switch, and the motor 2105 is powered by an external power supply. The output of the motor 2105 The end drives the transmission plate 2107 to rotate, and the transmission plate 2107 will rotate along the top of the guide frame 2101 with the output end of the motor 2105 as the center. The rotation of the transmission plate 2107 will drive the sliding telescopic rod 2108 to move synchronously. The sliding telescopic rod 2108 is a multi-section telescopic structure, which enables the sliding telescopic rod 2108 to automatically adjust its length according to the rotation angle of the transmission plate 2107. The L-shaped rod 2109 can connect the sliding telescopic rod 2108 with the rotating rod 2106, ensuring that when the sliding telescopic rod 2108 moves, it can drive the rotating rod 2106 to move accordingly. The rotating rod 2106 will move in the threaded groove 2102, and the hexagonal block 2111 is fixed on the rotating rod 2106. The surface of 111 contacts the inner wall of the thread groove 2102 to prevent the rotating rod 2106 from rotating unnecessarily during the movement. The thread groove 2102 provides a stable movement path for the rotating rod 2106, so that the rotating rod 2106 can move according to the predetermined path. Since the sliding telescopic rod 2108 has multiple sections of telescopicity, it can automatically adjust its length as the rotating rod 2106 moves in the thread groove 2102, thereby maintaining an effective connection with the rotating rod 2106. The movement of the rotating rod 2106 will drive the gear ring 2110 and the first pulley 2113 to move synchronously. When the rotating rod 2106 moves into the movable groove 2103 of the first layer, the movable groove 2103 will provide a rotatable space for the hexagonal block 2111. The surface of the gear ring 2110 will mesh with the surface of the rack 2104 of the first layer. As the transmission plate 2107 continues to move, the gear ring 2110 will be driven to rotate along the surface of the rack 2104. The rotation of the gear ring 2110 will drive the rotating rod 2106, the first pulley 2113, the hexagonal block 2111 and the limit plate 2112 to rotate synchronously, driving the fixed parts to flip. The limit plate 2112 can limit one end of the rotating rod 2106 to prevent the rotating rod 2106 from disengaging from the thread groove 2102 when moving. Then, the continuous operation of the output end of the motor 2105 drives the parts on the transmission plate 2107 to move under the detection lens. When the parts move to the bottom of the detection lens, the output end of the motor 2105 will stop operating.The inspection lens can inspect the part. After the inspection is completed, the motor 2105 will operate again to move the rotating rod 2106 to the second layer of the thread groove 2102. When the rotating rod 2106 moves to the second layer of the thread groove 2102, it will cooperate with the magnetic unit 22 to adsorb the inspected surface of the part. The rack 2104 on the second layer then drives the gear ring 2110 to rotate, thereby inspecting the uninspected surface of the part. The other uninspected surfaces can then be inspected through the third and fourth layers. When the side of the part needs to be inspected, the user manually places the side of the part under the inspection lens for inspection, reducing the number of manual flips by the worker and improving inspection efficiency.

[0033] The specific implementation of this embodiment is as follows: the first fixing plate 2203 and the second fixing plate 2202 can be limited and supported by the support frame 2201. The initial position of the second fixing plate 2202 is that the top of the second fixing plate 2202 is flush with the surface of the first fixing plate 2203. The user places the part on the first magnetic block 2205 of the first fixing plate 2203 and starts the first magnetic block 2205 through the external control switch. The first magnetic block 2205 is powered by an external power supply. The first magnetic block 2205 will adsorb one side of the part. When the first magnetic block 2205 is powered, the second magnetic block 2204 will be powered off. As the rotating rod 2106 enters the second layer of the thread groove 2102, the detection lens will detect the flipped part. 2202 is rotated, and the rotation of the first gear 2218 moves along the path of the meshing first toothed plate 2211, thereby driving the second fixed plate 2202 to rise. As the second fixed plate 2202 rises, the rotating rod 2217 on one side of the second fixed plate 2202 is rotated. 212 will drive the rotating ball 2216 to move along the path of the sliding rod 2233, and the sliding rod 2233 can prevent the second fixed plate 2202 from deflecting when moving. When the positioning groove 2226 of the second fixed plate 2202 moves to the top of the first fixed plate 2203, the user activates the second magnetic block 2204 on the second fixed plate 2202 through an external power supply. The second magnetic block 2204 will adsorb one side of the detected part. At this time, the first magnetic block 2205 will cancel the adsorption of the part, making it easier for the second magnetic block 2204 to adsorb the part. When the second supporting block 2232 completes the adsorption of the part, the first electric telescopic rod 2219 is activated again. The telescopic end of the first electric telescopic rod 2219 will retract, and the first electric telescopic rod 2219 will retract through the first The retracted telescopic end of the electric telescopic rod 2219 pulls the first motor 2217 to move backward. The first motor 2217 is connected to the first slider 2223. When the first motor 2217 is moved, the first slider 2223 moves on the first guide rail 2222.

The second guide rail 2230, the second slider 2231 and the second motor 2228 can be supported by the positioning plate 2227. The second gear 2229 on the output end of the second motor 2228 is pushed to a state of meshing with the second tooth plate 2214. The second motor 2228 is then started to drive the second gear 2229 through the output end of the second motor 2228. When the second gear 2229 rotates, the second gear 2229 drives the second tooth plate 2214 connected by the mounting block 2213 to move to the right side of the first fixed plate 2203. The mounting block 2213 moves along the path of the sliding groove 2215. When the second tooth plate 2214 moves to the right, it drives the adsorbed parts to move at the same time. The rotation of the rotating rod 2212 drives the rotating ball 2216 to rotate, which can adjust the direction of the rotating ball 2216 and move the rotating ball 2216 along the right end of the sliding rod 2233. There is a gap between the rotating ball 2216 and the sliding rod 2233, which can ensure the stability of the rotating ball 2216 when it rotates at the turning point of the sliding rod 2233, thereby adjusting the second fixed plate 2202 moving to the right. The guide, the slide bar 2233 can be fixed by the support block 2232. When the second fixed plate 2202 moves the part to the right side of the first fixed plate 2203 with the part, the surface of the part after passing through the first layer of rack 2104 will face upward, because the surface of the first layer of rack 2104 after rotation has been detected. Then start the motor 2105, and the motor 2105 drives the transmission plate 2107 and the part adsorbed by the second magnetic block 2204 to move toward the direction of the second layer of rack 2104. Then, the ring gear 2110 rotates along the surface of the second layer of rack 2104. The rotation of the ring gear 2110 will drive the rotating rod 2106 and the first pulley 2113 to rotate synchronously. The first pulley 2113 will drive the belt 2208 to rotate, and the belt 2 The rotation of 208 will drive the second pulley 2207 on the connecting rod 2206 to rotate, and the second pulley 2207 will drive the connecting rod 2206 to rotate synchronously. The connecting rod 2206 will drive the first fixed plate 2203 and the second fixed plate 2202 to rotate, thereby adjusting the position of the adsorbed parts. As the first fixed plate 2203 and the second fixed plate 2202 rotate, the first motor 2217 is driven to move along the annular groove 2210 in the annular frame 2209. The first motor 2217 and the sliding block 2224 can be connected by the first electric telescopic rod 2219. The sliding block 2224 will move in the annular groove 2210, thereby ensuring the stability of the first fixed plate 2203 and the second fixed plate 2202 after rotation.This causes the part attracted by the second magnetic block 2204 to flip over, turning the undetected side of the part to the top, making it easier for the inspection lens to inspect. In the same way, the gear ring 2110 rotates on the surface of the rack 2104 on the third and fourth layers, driving the attracted part to rotate, thereby inspecting different sides of the part.

[0034] Example 3: Please refer to Figure 8 The present invention provides a technical solution: a quality inspection mechanism for the production of mechanical parts. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A light-proof mechanism 3 is provided at the bottom of the optical detection device 1. The light-proof mechanism 3 is used in conjunction with the flip unit 21 and the magnetic unit 22. The light-proof mechanism 3 is used to block external light sources.

[0035] As a further limitation of the light-proof mechanism 3 of the present invention, the light-proof mechanism 3 includes a limit frame 301, the limit frame 301 is fixedly connected to the bottom of the optical detection device 1, and a limit groove 302 is provided on the inner wall of the limit frame 301. The inner wall of the limit groove 302 is slidably connected with a roller 303. There are three rollers 303, and the bottoms of the three rollers 303 are fixedly connected with a fixed rod 304. The bottoms of the fixed rod 304 are fixedly connected with a light-shielding plate 305. By setting the light-proof mechanism 3 and manually adjusting the position of the light-shielding plate 305, strong light from the outside can be quickly blocked. By reducing the interference of external light, the detection lens can capture effective information of the parts more quickly, thereby shortening the detection time and improving the detection efficiency and detection accuracy.

[0036] The specific implementation method of this embodiment is as follows: after the adsorbed part is rotated under the detection lens of the optical rotation device, when the user finds that the position of the light shielding plate 305 needs to be adjusted to block the external light source, the user pulls the light shielding plate 305, and the light shielding plate 305 transmits the force to the roller 303 through the fixing rod 304, and the roller 303 moves in the limit groove 302 of the limit frame 301. The limit frame 301 is annular and provides a continuous moving track for the light shielding plate 305. The light shielding plate 305 can move freely along the limit groove 302 in the annular frame 2209, so that the user can adjust the position of the light shielding plate 305 according to actual needs to achieve the best light shielding effect. After the light shielding plate 305 is adjusted to the position, the external light source will be effectively blocked, and the detection lens can more accurately capture the image information of the part surface.
