Description

Technical Field

[0001] This invention relates to the field of visual inspection, specifically to a visual inspection device for the production of new material sliders. Background Technology

[0002] New material sliders prepared by powder metallurgy are widely used in the field of precision machinery. After the sliders are sintered, multiple indicators such as hole diameter, shape contour and surface defects need to be accurately tested in order to screen out workpieces that meet the assembly requirements. Machine vision inspection equipment, with its advantages of fast detection speed and high measurement accuracy, is gradually replacing traditional manual caliper inspection and is widely used in the mass production quality inspection process of sliders.

[0003] Existing visual inspection devices generally include a frame, a measuring stage, a front light source, a rear light source, and a camera lens. The slider workpiece is placed on the installation position of the measuring stage, and supplementary lighting is provided by the front and rear light sources. The camera lens then captures images of the workpiece, and image processing algorithms are used to determine the size and appearance defects.

[0004] In actual production operations, after the workpiece is placed on the measuring platform, its position is prone to shifting. This often requires workers to repeatedly move and correct the slider's position to ensure the workpiece is within the effective field of view of the camera lens. These multiple position adjustments consume a significant amount of time, making the inspection preparation process cumbersome and hindering continuous and rapid inspection on the production line. Furthermore, after image acquisition and output of pass or fail inspection results, manual sorting is still required. Good and defective products must be manually placed in their respective storage areas. This repetitive sorting process can easily lead to visual and sensory fatigue, resulting in good and defective products being mixed together. The reliability of product quality inspection and sorting needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a visual inspection device for the production of new material sliders, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection device for producing new material sliders, comprising a frame, an inspection camera and a loading frame, wherein the top of the loading frame is provided with a guide mechanism for adjusting the position of the slider, which includes a plurality of guide rollers evenly distributed along the top surface of the loading frame and side baffles and rear baffles fixedly installed on the top of the loading frame, as well as two sets of rear guide frames rotatably installed on the loading frame and offset from the guide rollers; The top of the guide roller protrudes from the top surface of the carrying frame, and the top surface of the carrying frame is inclined and perpendicular to the side baffle. A ball bearing is installed on the outer wall of the side baffle near the guide roller. The rear guide frame is located between the two guide rollers, and multiple sets of pulleys are installed on the top of the rear guide frame. The top of the pulleys does not protrude from the top of the two adjacent guide rollers of the rear guide frame. The frame is slidably mounted with multiple load plates for pushing the slider upward and lifting drivers for driving the load plates to rise and fall. The inner wall of the load frame is slidably mounted with an end pusher that contacts the end of the rear guide frame. The load frame is also equipped with a synchronizer so that when the load plate rises, it will drive the end pusher to move upward. A discharge rack for pushing out defective sliders is rotatably mounted in the loading plate. A blocking frame that cooperates with the discharge rack is rotatably mounted on the frame, and a rotation driver that is compatible with the blocking frame is installed inside the frame.

[0007] Preferably, the detection camera is located at the front end of the loading frame, the top of the frame is also provided with a rear light source located at the rear end of the loading frame, and the end of the detection camera near the loading frame is provided with a front light source. The rear baffle is installed on the top of the end of the cargo frame near the rear light source, and the side baffle is installed on the side wall of the cargo frame. The cross-section formed by the side baffle and the rear baffle is L-shaped. Multiple sets of ball bearings are provided on the outer wall of the side baffle.

[0008] Preferably, the lifting drive is a lifting frame and an electric push rod that cooperate with each other, or a scissor lift that is mounted on the frame and connected to multiple load plates; The lifting frame is slidably mounted on the machine frame and connected to the bottom of multiple load plates, and the bottom surface of the middle part of the lifting frame is connected to an electric push rod mounted on the machine frame.

[0009] Preferably, the synchronizer includes a transmission block slidably mounted on the outer wall of the bottom end of the end pusher and a transmission hook mounted on the bottom of the loading plate, with the outer end of the transmission hook located directly below the transmission block; The bottom of the end pusher is provided with a guide wheel that is rotatably mounted on the side wall of the transmission block on the outer wall near the inner wall of the loading frame. A separation block that cooperates with the guide wheel is installed on the inner wall of the loading frame to guide the guide wheel to move away from the transmission hook.

[0010] Preferably, the bottom of the end pusher is equipped with a plurality of springs connected to the transmission block, and the top corner of the outer end of the transmission block is designed at an angle to match the outer end of the transmission hook.

[0011] Preferably, the bottom surface of the separating block is designed with an incline, and the separating block is located directly above the guide wheel, and the installation position of the separating block is staggered from the lifting trajectory of the end pusher.

[0012] Preferably, the carrier plate has a movable groove adapted to the discharge rack and the blocking rack, and the end of the discharge rack near the detection camera is rotatably connected to the carrier plate, while the bottom of the other end is fixed with an end support plate, which is slidably connected to the carrier plate.

[0013] Preferably, a plurality of pulleys are installed at equal intervals on the top of the material rack, and the plane on which the top of each pulley is located is lower than the plane on which the top of the load plate is located; The length of the blocking frame is less than the length of the bottom opening of the movable groove, and the end of the blocking frame near the discharge frame is rotatably equipped with pulley three.

[0014] Preferably, the rotary driver is a stepper motor connected to the blocking frame, or a hydraulic cylinder whose two ends are respectively rotatably connected to the side wall of the blocking frame and the frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a loading frame with an inclined top surface, allows the slider to slide along the guide roller towards the side baffle after placement. During the lifting of the loading plate, the end pusher drives the rear guide frame to swing, performing secondary position correction on the slider. This reduces the need for manual repetitive movement and correction of the slider, simplifies the preparation process before inspection, and facilitates continuous inspection operations on the production line. Furthermore, after inspection, it can automatically export unqualified sliders, reducing manual sorting operations, minimizing material mixing caused by personnel fatigue, and improving the reliability of quality inspection and sorting.

[0016] 2. The synchronizer of this invention can drive the end pusher to move upward synchronously during the rising stage of the carrier plate. After the guide wheel contacts the inclined surface of the separation block, it will drive the transmission block to shift, thereby releasing the transmission relationship between the carrier plate and the end pusher, so that the rear guide frame falls back in advance and will not continue to rise with the carrier plate. This avoids interference between the rear guide frame and the pulley, preventing the slider from entering the camera's field of view with the carrier plate, and ensuring the normal operation of image acquisition. At the same time, multiple sets of ball bearings are installed on the outer wall of the side baffle, and a pulley is set on the top of the rear guide frame. During the slider position adjustment process, the pulley will contact the ball bearings and pulley, reducing the frictional resistance encountered by the slider during the sliding adjustment process, reducing the possibility of the slider surface being scratched, and reducing the workpiece damage caused by the slider positioning process.

[0017] 3. In this invention, the discharge rack and the blocking rack work together. The discharge rack rotates due to the downward movement of the carrying plate, which pushes out the unqualified sliders. Users do not need to place the sliders according to whether they are qualified or unqualified. The sorting can be completed directly by the equipment, reducing the probability of placing the wrong slider. At the same time, a pulley is set at the end of the discharge rack to reduce the friction between the slider and the discharge rack when it slides out, reducing the probability of jamming in the discharge process and facilitating the smooth sliding out of the unqualified sliders.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9The present invention provides the following technical solution: a visual inspection device for producing new material sliders, comprising a frame 1, an inspection camera 2, and a carrying frame 3. The top of the carrying frame 3 is provided with a guide mechanism for adjusting the slider position. The guide mechanism includes multiple guide rollers 4 evenly distributed along the top surface of the carrying frame 3, side baffles 5 and rear baffles 6 fixedly installed on the top of the carrying frame 3, and two sets of rear guide frames 7 rotatably installed on the carrying frame 3 and offset from the guide rollers 4. The top of the guide rollers 4 protrudes from the top surface of the carrying frame 3, and the top surface of the carrying frame 3 is inclined and perpendicular to the side baffles 5. A ball bearing 51 is installed on the outer wall of the side baffle 5 near the guide rollers 4. The rear guide frames 7 are located between the two guide rollers 4, and multiple sets of pulleys 8 are installed on the top of the rear guide frames 7. The tops of the pulleys 8 do not protrude from the tops of the two adjacent guide rollers 4 of the rear guide frames 7. Multiple carrying plates 9 for pushing the slider upwards and a lifting driver for driving the carrying plates 9 to rise and fall are slidably installed on the frame 1. The inner wall of the carrying frame 3 is slidably installed with the rear guide frames. The end pusher 12 is in contact with the end of the 7, and a synchronizer is also provided in the carrying frame 3 to drive the end pusher 12 to move upward when the carrying plate 9 rises. A discharge rack 19 for pushing out unqualified sliders is rotatably installed in the carrying plate 9. A blocking rack 22 that cooperates with the discharge rack 19 is rotatably installed on the frame 1, and a rotation driver that is compatible with the blocking rack 22 is installed in the frame 1. A waste trough 24 is opened on the frame 1 between the carrying frame 3 and the detection camera 2. When in use, the slider is placed on the guide roller 4, and the guide roller 4 and the ball 51 set along the top slope of the carrying frame 3 complete the initial positioning. During the lifting process of the carrying plate 9, the end pusher 12 is driven by the synchronizer to drive the rear guide rack 7 to swing, and complete the secondary position adjustment of the slider. Then the carrying plate 9 will push the slider that has been adjusted to move upward to the detection position. After the detection is completed, if the slider is unqualified, the blocking rack 22 will cooperate with the discharge rack 19 to discharge the unqualified slider. If it is qualified, the discharge rack 19 will not be triggered to swing, and the user can take it away directly.

[0022] In one embodiment of the present invention, the detection camera 2 is located at the front end of the loading frame 3, and the top of the frame 1 is also provided with a rear light source 202 located at the rear end of the loading frame 3, and the detection camera 2 is provided with a front light source 201 at the end near the loading frame 3; the rear baffle 6 is installed on the top of the end of the loading frame 3 near the rear light source 202, the side baffle 5 is installed on the side wall of the loading frame 3, and the cross section formed by the side baffle 5 and the rear baffle 6 is L-shaped; multiple sets of ball bearings 51 are provided on the outer wall of the side baffle 5; the front light source 201 and the rear light source 202 provide supplementary lighting conditions for image acquisition; the L-shaped side baffle 5 and the rear baffle 6 play a limiting and guiding role on the two sides of the slider.

[0023] In one embodiment of the present invention, the lifting drive is selected from the mutually cooperating lifting frame 10 and electric push rod 11, or a scissor lift installed on the frame 1 and connected to multiple carrying plates 9; the lifting frame 10 is slidably installed on the frame 1 and connected to the bottom of multiple carrying plates 9, and the bottom surface of the middle part of the lifting frame 10 is connected to the electric push rod 11 installed on the frame 1. In use, the electric push rod 11 pushes the lifting frame 10 to move, or the scissor lift pushes the carrying plates 9 to move upward, thereby driving all carrying plates 9 to complete the lifting action synchronously.

[0024] In one embodiment of the present invention, the synchronizer includes a transmission block 13 slidably mounted on the outer wall of the bottom end of the end pusher 12, and a transmission hook 14 mounted on the bottom of the carrying plate 9, with the outer end of the transmission hook 14 located directly below the transmission block 13; a guide wheel 15 is slidably mounted on the outer wall of the bottom of the end pusher 12 near the inner wall of the carrying frame 3, and a separation block 16 cooperating with the guide wheel 15 is installed on the inner wall of the carrying frame 3. When the carrying plate 9 rises, the transmission hook 14 lifts the transmission block 13 and drives the end pusher 12 to move upward. After the guide wheel 15 contacts the separation block 16, the guide wheel 15 will drive the transmission block 13 to shift, so that the transmission hook 14 and the transmission block 13 are disengaged from each other.

[0025] In one embodiment of the present invention, a plurality of springs 17 connected to the transmission block 13 are installed in the bottom of the end pusher 12. The springs 17 apply a lateral force to the transmission block 13, and the top corner of the outer end of the transmission block 13 is designed to be at an angle to cooperate with the outer end of the transmission hook 14. When the transmission hook 14 moves downward, it will squeeze the angle of the transmission block 13, forcing the transmission block 13 to move toward the spring 17 and squeeze the spring 17, so that the transmission hook 14 can pass smoothly through the transmission block 13.

[0026] As one embodiment of the present invention, the bottom surface of the separating block 16 is designed with an inclined surface, and the separating block 16 is located directly above the guide wheel 15. When the separating block 16 with the inclined bottom surface contacts the guide wheel 15, it will force the guide wheel 15 to drive the transmission block 13 to move as the end push frame 12 moves upward. Furthermore, the installation position of the separating block 16 is staggered from the lifting trajectory of the end push frame 12, so as to avoid the setting of the separating block 16 affecting the lifting of the end push frame 12.

[0027] In one embodiment of the present invention, the loading plate 9 has an movable groove 18 adapted to the material rack 19 and the blocking frame 22. The end of the material rack 19 near the detection camera 2 is rotatably connected to the loading plate 9, and the bottom of the other end is fixed with an end support plate 21. The end support plate 21 is slidably connected to the loading plate 9. The movable groove 18 provides movement space for the material rack 19 and the blocking frame 22, and the end support plate 21 provides sliding support for the end of the material rack 19.

[0028] In one embodiment of the present invention, a plurality of pulleys 20 are installed at equal intervals on the top of the discharge rack 19, and the plane on which the top of the pulleys 20 is located is lower than the plane on which the top of the carrying plate 9 is located; the length of the blocking frame 22 is less than the length of the bottom opening of the movable groove 18, and a pulley 23 is rotatably installed on the end of the blocking frame 22 near the discharge rack 19. The pulleys 20 reduce the frictional resistance of the defective slider sliding outward, while the pulleys 23 reduce the friction at the contact point between the blocking frame 22 and the discharge rack 19.

[0029] In one embodiment of the present invention, the rotary driver is a stepper motor connected to the blocking frame 22, or a hydraulic cylinder whose two ends are respectively rotatably connected to the side wall of the blocking frame 22 and the frame 1. The blocking frame 22 can be driven to complete the swinging action by running the stepper motor or the hydraulic cylinder.

[0030] It should be noted that torsion springs adapted to the rear guide frame 7 and the discharge frame 19 can be added according to actual usage requirements.

[0031] Working principle: Under normal testing conditions, the electric push rod 11 is in the retracted state, and the lifting frame 10 drives all the carrying plates 9 to maintain a low position. At this time, the carrying plates 9 are retracted to below the top surface of the carrying frame 3, while the transmission hook 14 is located directly below the transmission block 13. At the same time, the spring 17 remains extended. In this state, the guide wheel 15 is located below the separating block 16, and the end push frame 12 is restricted by the carrying frame 3 and is in the lowest position. The rear guide frame 7 remains in a flat position. Under this condition, the top surface of pulley 8 is lower than the top surface of guide roller 4; the discharge rack 19 is supported by the end of the loading plate 9 and remains horizontal; the blocking rack 22 on the frame 1 is in a state away from the discharge rack 19; at the same time, the front light source 201, the rear light source 202 and the detection camera 2 are in a standby state. When visual inspection is required, first place the slider on the guide roller 4 of the loading frame 3. Because the top surface of the loading frame 3 is designed with an incline, the slider slides along the guide roller 4 set on the top incline of the loading frame 3 towards the side baffle 5 until it fits against the multiple sets of balls 51 on the side baffle 5. Then the electric push rod 11 is operated, which will push the lifting frame 10 to move upward, so that the lifting frame 10 will simultaneously drive multiple sets of carrying plates 9 to rise upward. During the rising process of the carrying plate 9, the transmission hook 14 at its bottom contacts the bottom surface of the transmission block 13, so that the transmission hook 14 will simultaneously lift the transmission block 13, causing the transmission block 13 to drive the end push frame 12 to move upward in sync. The upward-moving end pusher 12 will simultaneously push up the two sets of rear guide frames 7, causing the rear guide frames 7 to swing upward. At this time, the pulley 8 will push up the slider above the guide roller 4. Because the rear guide frame 7 is rotatably connected to the side of the loading frame 3 where the rear baffle 6 is installed, the rear guide frame 7 is tilted towards the rear baffle 6. This causes the slider to slide along multiple sets of balls 51 under the guidance of the pulley 8, and the position of the slider is adjusted a second time. As the end pusher 12 continues to move upward, the guide wheel 15 on the outer wall of the end pusher 12 will contact the separation block 16 on the inner wall of the carrying frame 3, causing the inclined surface of the separation block 16 to press the guide wheel 15, forcing the guide wheel 15 to drive the transmission block 13 to slide inward and compress the spring 17, thereby causing the transmission block 13 and the transmission hook 14 to be misaligned. At this time, the end pusher 12 loses the support of the transmission hook 14, and then the rear guide frame 7 and the end pusher 12 will fall back to reset. At the same time, the pulley 8 falls back to a position lower than the top surface of the guide roller 4 and no longer contacts the slider. When the guide wheel 15 contacts the separator block 16, the carrying plate 9 has moved up to the state of contacting the bottom surface of the slider. When the end pusher 12 is reset, the carrying plate 9 begins to move upward, driving the slider upward. Subsequently, the electric push rod 11 continues to lift the lifting frame 10, so that the carrier plate 9 carries the slider and moves it into the shooting field of view of the inspection camera 2. The front light source 201 and the rear light source 202 are turned on to complete the supplementary lighting. The inspection camera 2 acquires the slider image and transmits the image data to the image processing system to complete the identification and judgment of the slider's aperture, outline, and surface defects, and outputs the inspection result of good or defective products. If the workpiece is determined to be good, the rotary drive on the frame 1 will not drive the blocking frame 22 to move, and the blocking frame 22 will remain in the storage state. Then the electric push rod 11 will drive the lifting frame 10 and the carrying plate 9 to reset downwards. Then the user can directly take away the qualified slider. If the workpiece is determined to be defective, the rotary driver will drive the blocking frame 22 to swing upward, causing the pulley 3 23 at the end of the blocking frame 22 to extend upward into the movable groove 18. During the downward fall of the carrying plate 9, it will directly contact the pulley 3 23, thereby lifting the end of the discharge rack 19 away from the inspection camera 2 upward. Subsequently, the defective slider will slide outward along the pulley 2 20 on the top surface of the discharge rack 19 and fall into the waste trough 24 under the guidance of the pulley 2 20 and the discharge rack 19, so that the defective slider will be automatically rejected. After the inspection is completed, the user can directly pick up the slider that has not been removed, avoiding the probability of picking up the slider incorrectly. After the discharge action is completed, the rotary driver will automatically drive the blocking frame 22 to reset, so that the discharge rack 19 will fall back to the horizontal state by its own weight, waiting for the next inspection operation. After the entire testing process is completed, the electric actuator 11 retracts, and all components return to their initial standby position, allowing for continuous batch loading, positioning, image acquisition, and sorting of sliders.
