[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0015] Reference Figures 1-6As shown, a visual inspection device for valve cover installation includes a housing 1. A first fixing frame 2 and a guide rail 26 are fixedly connected to the front end of the housing 1. A movable stage 3 is slidably connected inside the guide rail 26. A detection stage 4 is fixedly connected to the bottom inner side of the housing 1. A servo motor 5 is fixedly installed on the top inner side of the detection stage 4. The output end of the servo motor 5 passes through the top inner side of the detection stage 4 and is fixedly connected to a turntable 6. A docking platform 7 is fixedly connected to the upper end of the turntable 6. Multiple docking slots 8 are provided on the upper ends of both the docking platform 7 and the movable stage 3. A guide seat 9 is inserted into the inside of the docking slot 8. A placement platform 10 is fixedly connected to the upper end of the guide seat 9. A receiving cavity 11 is provided on the upper end of the placement platform 10. A support is fixedly connected to the bottom inner side of the housing 1 behind the detection stage 4. A machine vision camera 13 is mounted on the upper end of column 12. A slide groove 14 is opened on the inner top of the housing 1. A first lead screw 15 is rotatably connected inside the slide groove 14. A second lead screw 16 is rotatably connected between the inner walls of the left and right sides of the first fixed frame 2. A first slide block 17 is threadedly connected to the outer surface of the second lead screw 16. A second slide block 20 is threadedly connected to the outer surface of the first lead screw 15. Multiple evenly distributed first hydraulic rods 18 are fixedly installed at the lower ends of the second slide block 20 and the first slide block 17. A second fixed frame 19 is fixedly connected to the output end of the first hydraulic rod 18. A bidirectional lead screw 21 is rotatably connected between the inner walls of the left and right sides of the second fixed frame 19. Two symmetrically distributed clamping plates 22 are threadedly connected to the outer surface of the bidirectional lead screw 21.
[0016] Furthermore, the interior of the receiving cavity 11 is used to place a lead-acid battery, and the shape and size of the receiving cavity 11 are adapted to the shape of the lead-acid battery to be tested.
[0017] Furthermore, the guide rail 26 is internally rotatably connected to a third lead screw 27, and the movable table 3 is threadedly connected to the outer surface of the third lead screw 27.
[0018] Furthermore, the rotation of the first lead screw 15, the second lead screw 16, the bidirectional lead screw 21, and the third lead screw 27 are all driven by external motors.
[0019] Furthermore, the lens of the machine vision camera 13 is positioned above the inspection table 4 to capture images of the lead-acid battery valve cover installation location placed above the inspection table 4 in real time. Simultaneously, the image data is transmitted to an external control device, which uses algorithms to analyze whether the valve cover has defects such as offset, tilt, or omission. The servo motor 5 drives the turntable 6 to rotate, thereby causing the lead-acid battery placed on the placement table 10 to rotate synchronously. This allows the machine vision camera 13 to capture 360° images of the valve cover, avoiding the omission of side defects when capturing images from a single angle.
[0020] Furthermore, a fixing plate 23 is fixedly connected to the rear end of the left second fixing frame 19 and the front end of the right second fixing frame 19. A second hydraulic rod 24 is fixedly installed at the end of the fixing plate 23 away from the second fixing frame 19. The output end of the second hydraulic rod 24 passes through the end of the fixing plate 23 away from the second fixing frame 19 and is fixedly connected to a push plate 25.
[0021] Furthermore, the initial position of the clamping plate 22 at the lower end of the first slide 17 is directly above the discharge port of the valve cover mounting device. The workpiece delivered from the discharge port of the valve cover mounting device is the placement platform 10 and the lead-acid battery with the valve cover already installed, placed inside the receiving cavity 11. The clamping plate 22 at the lower end of the first slide 17 can grip and transfer the placement platform 10 carrying the lead-acid battery to directly above the moving platform 3. After the placement platform 10 carrying the lead-acid battery is transferred to directly above the moving platform 3, the rotation of the first lead screw 15 causes the second slide to... When slide 20 moves to the frontmost position, the clamping plate 22 at the lower end of the second slide 20 is directly opposite the clamping plate 22 at the lower end of the first slide 17. The push plate 25 is pushed by the second hydraulic rod 24 at the lower end of the first slide 17, which pushes the placement platform 10 carrying the lead-acid battery between the two clamping plates 22 at the lower end of the second slide 20. Then, the first lead screw 15 rotates, causing the second slide 20 to move directly above the testing platform 4. At this point, the first hydraulic rod 18 at the lower end of the second slide 20 moves the placement platform 10 downwards, causing the guide at the lower end of the placement platform 10 to... Inserting seat 9 into docking groove 8 allows placement platform 10 to be placed on docking platform 7. After placement, bidirectional lead screw 21 rotates, causing the two clamping plates 22 to move away from each other, releasing placement platform 10. Then, the second fixing bracket 19 at the lower end of the second slide 20 retracts and resets. At this time, servo motor 5 drives turntable 6 to rotate, causing placement platform 10 to rotate. Machine vision camera 13 captures real-time images of the lead-acid battery valve cover installation location and feeds them back to external control equipment for data analysis, thereby determining whether the valve cover installation is qualified. After the inspection is completed, the second slide... The clamping plate 22 at the lower end of the seat 20 grips the placement table 10 again. After gripping, the first lead screw 15 rotates, moving the second slide 20 to the front end. At this time, the second hydraulic rod 24 on the second slide 20 pushes the push plate 25 to make the placement table 10 return to the two clamping plates 22 at the lower end of the first slide 17. Then, the first hydraulic rod 18 on the first slide 17 drives the placement table 10 to descend and place it on the moving table 3. After placement, the third lead screw 27 rotates, and the moving table 3 moves the lead-acid battery that has completed the test to the next stage.
[0022] Furthermore, supplementary lights 28 are fixedly connected to both sides of the support column 12 via support rods. The supplementary lights 28 are used to provide uniform diffused light during the inspection process of the machine vision camera 13, eliminate the shadow between the lead-acid battery casing and the valve cover, improve image clarity, and avoid misidentification caused by uneven light.
[0023] Furthermore, the first guide rod 29 is fixedly connected to the left and right inner walls of the first fixed frame 2 on both the front and rear sides of the second lead screw 16, and the first slide block 17 is slidably connected to the outer surface of the first guide rod 29.
[0024] Furthermore, the second guide rods 30 are fixedly connected to the inner walls of the left and right sides of the second fixed frame 19, located on the front and rear sides of the bidirectional lead screw 21, and the clamping plate 22 is slidably connected to the outer surface of the second guide rods 30.
[0025] Working principle: During use, the valve cover installation device discharges the placement platform 10 and the lead-acid battery with the valve cover installed from the outlet. The lead-acid battery is placed inside the receiving cavity 11. Then, the motor drives the second lead screw 16 to rotate, causing the first slide 17 to move directly above the outlet. Next, the first hydraulic rod 18 extends, causing the second fixing frame 19 to descend. Then, the motor drives the bidirectional lead screw 21 to rotate, causing the two clamping plates 22 to clamp the placement platform 10. After that, the first hydraulic rod 18 retracts, lifting the placement platform 10. At the same time, the second lead screw 16 drives the first slide 17 to move to the designated position. Above the moving platform 3, after the first slide block 17 moves to a position directly above the moving platform 3, the first lead screw 15 is driven by the motor to rotate, causing the second slide block 20 to move to the front end of the slide groove 14, so that the clamping plate 22 of the second slide block 20 is directly opposite the clamping plate 22 of the first slide block 17. At this time, the second hydraulic rod 24 at the lower end of the first slide block 17 extends, pushing the push plate 25 to push the placement platform 10 from the clamping plate 22 of the first slide block 17 to the clamping plate 22 of the second slide block 20. When the placement platform 10 reaches the clamping plate 22 of the second slide block 20, the motor drives the first lead screw 15 to rotate. The second slide 20 is moved to directly above the inspection table 4. Then, the first hydraulic rod 18 extends, causing the guide seat 9 to insert into the docking groove 8 of the docking table 7. Next, the clamping plate 22 is released, and the first hydraulic rod 18 retracts and resets, completing the placement of the placement table 10. Afterward, the supplementary light 28 is turned on, and the servo motor 5 drives the turntable 6 to rotate, causing the placement table 10 to rotate synchronously with the battery. The machine vision camera 13 captures real-time images of the valve cover and transmits them to an external control device. The control device analyzes the results (pass or fail) using algorithms. After the inspection is completed, the second slide 20... Clamping plate 22 clamps the placement platform 10 again, the first hydraulic rod 18 retracts and lifts the placement platform 10, and then the first lead screw 15 rotates to drive the second slide block 20 to move to the front end of the slide groove 14. The second hydraulic rod 24 of the second slide block 20 extends and pushes the push plate 25 to push the placement platform 10 back to the clamping plate 22 of the first slide block 17. Then the first hydraulic rod 18 extends, so that the guide seat 9 of the placement platform 10 inserts into the docking groove 8 of the moving platform 3 and places the placement platform 10 on the moving platform 3. Then the third lead screw 27 rotates and the moving platform 3 delivers the battery to the next stage.
