Technical Field

[0001] This utility model relates to the technical field of optical inspection equipment, specifically to an optical sorting machine for automotive engine spring bearings. Background Technology

[0002] The valve seat ring is a key component in the engine valve assembly. Typically a ring-shaped structure made of metal, it secures and supports the valve spring, ensuring it maintains the correct position and orientation during engine operation. This allows the valves to open and close precisely according to the engine's working cycle, guaranteeing the smoothness and stability of the engine's intake and exhaust processes. It plays a crucial role in the engine's power output, fuel economy, and overall performance. In automotive parts inspection, optical inspection technology can quickly and accurately acquire surface and geometric feature information of parts, providing strong support for quality control.

[0003] In existing technical solutions, when the feeder places the car engine spring seats to be tested one by one into the optical sorting machine, the limited feeding accuracy and stability of the feeder result in inconsistencies in the placement of the spring seats within the optical sorting machine. Since the detection mechanism within the optical sorting machine has a fixed position, the spring seats cannot always be accurately positioned in the optimal detection location. This makes it difficult for the detection mechanism to obtain clear and accurate image information, thus affecting the accuracy of the detection results and easily leading to false positives and false negatives.

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0023] First Embodiment

[0024] Please see Figs. 1 to 4As shown, an optical sorting machine for automotive engine spring seats includes a worktable 1, a turntable 2, a feeding mechanism 3, and an adjusting mechanism 4. The turntable 2 is rotatably connected to the top of the worktable 1. The feeding mechanism 3 is located on one side of the worktable 1 and is used to place the automotive engine spring seats to be inspected one by one on the top of the turntable 2. The adjusting mechanism 4 includes a support frame 5, a movable slide 6, and a guide plate 7. The support frame 5 is fixedly connected to the top of the worktable 1. The movable slide 6 is slidably arranged on the side of the support frame 5 in a vertical direction. The movable slide 6 has two symmetrically arranged first slide grooves 8 and second slide grooves 9. The two ends of the guide plate 7 are slidably arranged in the first slide groove 8 and the second slide groove 9, respectively. There are two guide plates 7. The distance between the ends of the two guide plates 7 in the first slide groove 8 is greater than the distance between the ends of the two guide plates 7 in the second slide groove 9.

[0025] When the optical sorting machine for automotive engine spring seats is in operation, the feeding mechanism 3 places the spring seats to be inspected one by one on top of the rotating turntable 2. The rotation of the turntable 2 moves the spring seats, at which point the positioning mechanism 4 comes into play. The movable slide 6 slides vertically along the support frame 5, adjusting to the appropriate position according to the height of the turntable 2 for different models. This avoids friction between the bottom of the guide plate 7 and the turntable 2, while preparing for subsequent guiding and limiting. Next, the two guide plates 7 slide within the first slide groove 8 and the second slide groove 9. Because the distance between the ends of the guide plates 7 in the first slide groove 8 is greater than that in the second slide groove 9, when the spring seats pass through, the sides of the guide plates 7 provide guidance and limiting, adjusting the spring seats to the appropriate position and posture on the turntable 2, precisely entering the optimal detection range of the inspection mechanism. The inspection mechanism then obtains clear and accurate image information, completing the quality inspection and sorting of the spring seats.

[0026] It should be specifically noted that the testing organization includes a camera assembly for collecting visual information and a light source assembly that provides the basic conditions for imaging by the camera assembly. The specific components and installation positions of the camera assembly and light source assembly can be replaced and set according to the actual usage environment and conditions, and there are no restrictions here.

[0027] By sliding the movable carriage 6 and the support frame 5 together, the height of the guide plate 7 can be adapted to different models of turntable 2, avoiding friction between the guide plate 7 and the turntable 2. The guide plate 7 guides and limits the spring seat ring by sliding in the groove, ensuring that the spring seat ring is accurately in the optimal detection position of the detection mechanism every time. This allows the detection mechanism to obtain clear and accurate image information, effectively improving the accuracy of the detection results, greatly reducing the occurrence of false detections and missed detections, ensuring the product quality of automotive engine spring seat rings, and thus improving the overall performance and reliability of automotive engines.

[0028] Second Embodiment

[0029] Based on the first embodiment, two symmetrically arranged first screws 10 are fixedly installed on the top of the guide plate 7. The first screws 10 are slidably disposed in the first slide groove 8 and the second slide groove 9, respectively. Locking nuts 11 are fitted on the sides of each of the first screws 10. Elastic pads 12 are also fitted on the sides of the first screws 10. The bottom of the elastic pads 12 abuts against the movable slide 6, and the top of the elastic pads 12 abuts against the locking nuts 11. When it is necessary to adjust the position of the guide plate 7 to adapt to the guiding requirements of spring seats of different specifications, the locking nuts 11 are loosened first to release the fixing constraint on the first screws 10. At this time, both ends of the guide plate 7 can slide freely in the first slide groove 8 and the second slide groove 9. By adjusting the spacing and position of the guide plates 7, the limiting and guiding angle and range of the spring seats can be changed. After adjustment, tighten the locking nut 11 so that it presses against the elastic pad 12 between the nut and the movable slide 6. The friction generated by the deformation of the elastic pad 12 will securely lock the first screw 10, thereby fixing the position of the guide plate 7.

[0030] Third Embodiment

[0031] Based on the first embodiment, the guide plate 7 includes a groove plate 13 and an insert plate 14. One end of the groove plate 13 is slidably connected to the first sliding groove 8, and the other end of the groove plate 13 has a slot. One end of the insert plate 14 is fixedly provided with an insert block that is slidably connected to the slot, and the other end of the insert plate 14 is slidably connected to the second sliding groove 9. When the position of the guide plate 7 is adjusted according to the size specifications of the spring seat ring, as both ends of the guide plate 7 slide in the first sliding groove 8 and the second sliding groove 9, the insertion depth of the insert plate 14 in the slot will also change accordingly, thereby changing the overall length and spacing of the guide plate 7.

[0032] Fourth embodiment

[0033] Based on the first embodiment, the support frame 5 has a vertical slide groove 15 on its side. The movable slide 6 is slidably connected to the vertical slide groove 15. A second screw 16 in a vertical position is rotatably disposed within the vertical slide groove 15. The movable slide 6 has a screw hole that is threadedly connected to the second screw 16. An adjusting handwheel 17 is rotatably disposed on the top of the support frame 5, and the adjusting handwheel 17 is coaxially and fixedly connected to the second screw 16. By rotating the adjusting handwheel 17, the second screw 16 is rotated, and the movable slide 6 slides up and down along the vertical slide groove 15 through the screw hole, precisely adjusting the height of the guide plate 7 to match the height of different models of turntables 2. This avoids friction between the guide plate 7 and the turntable 2 while ensuring the guiding accuracy of the spring seat ring.

[0034] Fifth Embodiment

[0035] Based on the first embodiment, a mounting frame 18 is fixedly installed on the top of the workbench 1, and a drive motor 19 is fixedly installed on the mounting frame 18. The output end of the drive motor 19 is coaxially and fixedly connected to the bottom of the turntable 2. Several first universal wheels 20 arranged in a matrix are fixedly installed on the bottom of the workbench 1. By starting the drive motor 19, the turntable 2 is driven to rotate. The feeding mechanism 3 places the spring seat ring on the turntable 2. The rotation of the turntable 2 causes the spring seat ring to move. The positioning mechanism 4 guides and limits the spring seat ring, so that it accurately enters the optimal detection range of the detection mechanism to complete the detection and screening. The first universal wheels 20 facilitate the movement and handling of the equipment.

[0036] Sixth Embodiment

[0037] Based on the first embodiment, the feeding mechanism 3 includes a centrifugal feeder, which is disposed on one side of the workbench 1, and the output end of the centrifugal feeder is located directly above the turntable 2. The feeding mechanism 3 also includes a number of second universal wheels 21, which are arranged in a matrix at the bottom of the centrifugal feeder.

[0038] The centrifugal feeder uses centrifugal force to throw the spring seats to be tested one by one, causing them to fall onto the top of the turntable 2. As the turntable 2 rotates, the positioning mechanism 4 guides and limits the spring seats, ensuring they precisely enter the optimal testing range of the testing mechanism, thus completing the testing and screening. The second caster wheel 21 facilitates the movement and position adjustment of the centrifugal feeder.

[0039] Seventh Embodiment

[0040] Based on the first embodiment, the feeding mechanism 3 includes a vibrating feeder, which is disposed on one side of the workbench 1, and the output end of the vibrating feeder is located directly above the turntable 2. The feeding mechanism 3 also includes a number of second casters 21, which are arranged in a matrix at the bottom of the vibrating feeder.

[0041] The vibrating feeder uses vibration to move the spring rings to be tested along the track in an orderly manner, causing them to fall one by one onto the top of the turntable 2. As the turntable 2 rotates, the positioning mechanism 4 guides and limits the spring rings, ensuring they accurately enter the optimal testing range of the testing mechanism, thus completing the testing and screening. The second universal wheel 21 facilitates the movement and position adjustment of the vibrating feeder.

[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
