Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a battery water washing quality testing device. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the water washing process is a crucial step in removing residual electrolyte, dust, and metal debris from the battery surface. The cleanliness after washing directly affects the appearance quality of the battery, therefore, strict quality inspection of the battery's outer surface is necessary. Traditional inspection mainly relies on manual visual inspection or semi-automatic sampling, which has significant drawbacks: manual inspection is slow and prone to missed inspections due to visual fatigue, especially with limited ability to identify tiny stains and watermarks; while existing automated equipment mostly uses single-angle visual scanning, which cannot fully cover all four sides of the battery, requiring multiple industrial cameras, increasing system complexity and cost.

[0003] After inspection, qualified products and reworked products need to be sorted according to the results. However, most equipment uses independent robotic arms to perform sorting, which has a long action path, slow cycle time, and is prone to errors in timing coordination with the inspection unit, affecting the continuity of the production line.

[0004] To address the aforementioned issues, there is an urgent need for a fully automated device that integrates efficient multi-faceted detection, precise sorting, and dynamic stable positioning to improve the intelligence level and production cycle of battery washing quality control. Utility Model Content

[0005] The main objective of this invention is to provide a testing device capable of detecting the quality of water-washed batteries.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A battery washing quality inspection device includes a base plate with a circular groove at its upper end. A turntable is rotatably mounted in the groove, with its upper end flush with the upper end of the base plate. A first motor is fixed at the lower end of the base plate, and the output shaft of the first motor is concentrically connected to the turntable. A discharge conveyor belt and a return conveyor belt are respectively mounted on the left and right sides of the base plate, with their upper ends flush with the upper end of the base plate. An infeed conveyor belt is mounted on the rear side of the base plate, with its upper end flush with the upper end of the base plate. A pushing unit is mounted on the infeed conveyor belt. A detection unit is mounted on the front side of the base plate, and a toggle unit is mounted above the detection unit. The toggle unit is fixedly connected to the base plate by multiple support rods. The pushing unit can push the batteries on the infeed conveyor belt onto the turntable. The first motor drives the turntable to rotate intermittently. The detection unit can sequentially inspect the four sides of the battery. If the battery is qualified, the toggle unit moves the battery onto the discharge conveyor belt; if the battery is unqualified, the toggle unit moves the battery onto the return conveyor belt.

[0007] Specifically, two stop bars are fixed at the upper end of the turntable, and the ends of the stop bars on the same side are machined with guide slopes.

[0008] Specifically, the pushing unit includes a telescopic rod, which is fixed to one side of the frame of the feeding conveyor belt. The axial direction of the telescopic rod is parallel to the conveying direction of the feeding conveyor belt. A long groove is opened on the telescopic end of the telescopic rod. One end of the push rod is rotatably set in the long groove through a rotating rod. The telescopic end of the telescopic rod is connected to one end of the push rod in the long groove through a torsion spring. The push rod is perpendicular to the telescopic rod. A limit rod is fixed on the telescopic end of the telescopic rod. The limit rod limits the push rod and keeps the push rod perpendicular to the telescopic rod. During the process of the battery moving towards the bottom plate on the feeding conveyor belt, the battery contacts the push rod, which enables the push rod to rotate around the rotating rod.

[0009] Specifically, the telescopic rod is an electric push rod, and a first photoelectric sensor is fixed on the end of the feed conveyor belt facing the bottom plate. The first photoelectric sensor, the telescopic rod, and the controller are electrically connected.

[0010] Specifically, the detection unit includes a support plate fixed to the upper end of the base plate, a second photoelectric sensor fixed to the upper end of the support plate, the second photoelectric sensor, the controller and the first motor being electrically connected, and an industrial camera fixed to the support plate, which is electrically connected to the controller.

[0011] Specifically, the actuation unit includes a guide rail, which is fixedly connected to multiple support rods. A lead screw is rotatably installed inside the guide rail. A second motor is fixed to one end of the guide rail, and the output shaft of the second motor is concentrically fixedly connected to the lead screw. A slider is slidably installed inside the guide rail, and the movement direction of the slider is parallel to the conveying direction of the discharge conveyor belt. The slider is threadedly connected to the lead screw. A third motor is fixed to the rear end of the slider. A lever is fixed to the output shaft of the third motor. The lever is inverted L-shaped. The output shaft of the third motor is fixedly connected to the lower end of the vertical part of the lever. The horizontal part of the lever is perpendicular to the guide rail and is located above the vertical part. A proximity sensor is fixed to the right end of the guide rail. The industrial camera, controller, second motor, third motor, and proximity sensor are electrically connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The turntable, in conjunction with an industrial camera, enables automatic rotational positioning and image acquisition of the battery's four sides. A single loading operation completes full-circle inspection, eliminating the need for manual flipping or multiple positioning steps, thus improving inspection efficiency. A stop bar limiting structure enhances the battery's stability during turntable rotation, maintaining a fixed relative distance between the industrial camera and the battery's side, ensuring consistent image acquisition and reducing false positives. This device can precisely trigger the telescopic rod's pushing action, turntable rotation, and industrial camera's shooting action, achieving a fully automated closed-loop process of inspection, rotation, and re-inspection, significantly shortening cycle time.

[0013] 2. The inverted L-shaped lever, in conjunction with the guide rail slider system, switches between working states via 180° rotation. A single mechanism can achieve bidirectional sorting of qualified products (discharge) and unqualified products (return), replacing the traditional dual-manipulator structure and significantly reducing equipment costs. Proximity sensors provide real-time feedback on the slider position, ensuring the lever moves to the preset sorting starting point and avoiding accumulated positional errors. The straight section of the lever pushes the batteries horizontally without lifting, ensuring a smooth and fast sorting process. The stop bar automatically aligns with the conveyor belt when the batteries exit the tray, reducing the risk of jamming.

[0014] 3. The guide ramp of the stop lever guides the battery precisely into the turntable's limiting area, and works in conjunction with the torsion spring-reset push rod to achieve a smooth connection between feeding and positioning. The limiting rod locks the push rod in a vertical state, ensuring that the pushing force and direction are constant and preventing the battery from tilting on the turntable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figures 1-4 As shown, a battery washing quality testing device includes a base plate 1, a circular groove is provided on the upper end of the base plate 1, a turntable 2 is rotatably arranged in the circular groove, the upper end of the turntable 2 is flush with the upper end of the base plate 1, a first motor 3 is fixed at the lower end of the base plate 1, and the output shaft of the first motor 3 is concentrically fixedly connected to the turntable 2.

[0022] The bottom plate 1 is provided with a discharge conveyor belt 6 and a return conveyor belt 7 on the left and right sides respectively. The upper ends of the discharge conveyor belt 6 and the return conveyor belt 7 are flush with the upper end of the bottom plate 1. The bottom plate 1 is provided with a feed conveyor belt 8 on the rear side. The upper end of the feed conveyor belt 8 is flush with the upper end of the bottom plate 1.

[0023] A pushing unit is provided on the feeding conveyor belt 8. The pushing unit can push the batteries on the feeding conveyor belt 8 onto the turntable 2.

[0024] The pushing unit includes a telescopic rod 9, which is fixed on one side of the frame of the feeding conveyor belt 8. The axial direction of the telescopic rod 9 is parallel to the conveying direction of the feeding conveyor belt 8. A long groove 11 is provided on the telescopic end of the telescopic rod 9. One end of the push rod 10 is rotatably set in the long groove 11 through the rotating rod 12.

[0025] The telescopic end of the telescopic rod 9 is connected to one end of the push rod 10 in the long groove 11 by a torsion spring.

[0026] The push rod 10 is perpendicular to the telescopic rod 9. A limit rod 13 is fixed on the telescopic end of the telescopic rod 9. The limit rod 13 limits the push rod 10 and keeps the push rod 10 perpendicular to the telescopic rod 9.

[0027] As the battery moves toward the base plate 1 on the feeding conveyor belt 8, the battery comes into contact with the push rod 10, which causes the push rod 10 to rotate around the rotating rod 12.

[0028] The telescopic rod 9 is an electric push rod 10. A first photoelectric sensor 25 is fixed on the end of the feed conveyor belt 8 facing the base plate 1. The first photoelectric sensor 25, the telescopic rod 9 and the controller are electrically connected.

[0029] A detection unit is installed on the front side of the base plate 1. The first motor 3 drives the turntable 2 to rotate intermittently, and the detection unit can sequentially detect the four sides of the battery.

[0030] The detection unit includes a support plate 14 fixed on the upper end of the base plate 1. A second photoelectric sensor 15 is fixed on the upper end of the support plate 14. The second photoelectric sensor 15, the controller, and the first motor 3 are electrically connected. An industrial camera 16 is fixed on the support plate 14. The industrial camera 16 is electrically connected to the controller.

[0031] A toggle unit is installed above the detection unit. The toggle unit is fixedly connected to the base plate 1 by multiple support rods 17. When the battery is qualified, the toggle unit moves the battery to the discharge conveyor belt 6. When the battery is unqualified, the toggle unit moves the battery to the return conveyor belt 7.

[0032] The actuating unit includes a guide rail 18, which is fixedly connected to multiple support rods 17. A lead screw 19 is rotatably mounted inside the guide rail 18. A second motor 20 is fixed to one end of the guide rail 18, and the output shaft of the second motor 20 is concentrically fixedly connected to the lead screw 19. A slider 21 is slidably mounted inside the guide rail 18, and the movement direction of the slider 21 is parallel to the conveying direction of the discharge conveyor belt 6. The slider 21 is threadedly connected to the lead screw 19. A third motor 22 is fixed to the rear end of the slider 21, and a lever 23 is fixed to the output shaft of the third motor 22. The lever 23 is inverted L-shaped, and the output shaft of the third motor 22 is fixedly connected to the lower end of the vertical part of the lever 23. The horizontal part of the lever 23 is perpendicular to the guide rail 18 and is located above the vertical part.

[0033] A proximity sensor 24 is fixed to the right end of the guide rail 18. The industrial camera 16, controller, second motor 20, third motor 22 and proximity sensor 24 are electrically connected.

[0034] During operation, the battery moves along the feeding conveyor belt 8 towards the base plate 1. As the battery moves along the feeding conveyor belt 8 towards the base plate 1, it contacts the push rod 10, causing the push rod 10 to rotate around the rotating rod 12. Simultaneously, the torsion spring stores energy. When the battery moves to the front of the push rod 10 and separates from it, the push rod 10 returns to its original position under the elastic force of the torsion spring. After returning to its original position, the push rod 10 is blocked by the limiting rod 13, at which point it is perpendicular to the telescopic rod 9. When the first photoelectric sensor 25 detects the battery on the feeding conveyor belt 8, it sends a signal to the controller. The controller then activates the telescopic rod 9, and the telescopic end of the telescopic rod 9 drives the push rod 10 forward, pushing the battery on the feeding conveyor belt 8 to the upper end of the turntable 2.

[0035] When the second photoelectric sensor 15 detects the battery on the turntable 2, it sends a signal to the controller. The controller then activates the industrial camera 16. The industrial camera 16 acquires images of the side of the battery facing it through its lens, transmitting analog electrical signals to the controller via a data interface. The controller receives the data, converts the signals into digital signals using an analog-to-digital converter, and stores them in its memory. The controller then preprocesses the received image data (e.g., noise reduction and enhancement), followed by feature extraction and target detection. The controller compares the acquired images with preset templates or algorithms to identify differences or similar features. If the comparison passes, the controller activates the first motor 3, which drives the turntable 2 and the battery to rotate 90 degrees. The industrial camera 16 then continues to acquire images of the next side of the battery, and the controller performs comparison processing.

[0036] When there is dirt on one side of the battery, the comparison fails. The controller controls the first motor 3, which in turn causes the turntable 2 to rotate and reset.

[0037] The controller then activates the second motor 20, which drives the lead screw 19 to rotate forward. This causes the slider 21, the third motor 22, and the lever 23 to move to the left, with the straight portion of the lever 23 passing over the space above the battery. When the proximity sensor 24 no longer detects the third motor 22, the second motor 20 stops. At this point, the lever 23 is positioned to the left of the battery.

[0038] Then the controller starts the third motor 22, which drives the lever 23 to rotate 180 degrees. At this time, the straight part of the lever 23 is below the vertical part. Then the controller starts the second motor 20, which drives the lead screw 19 to rotate in the opposite direction, thereby causing the slider 21, the third motor 22, and the lever 23 to move to the right. During the movement of the lever 23 to the right, the straight part of the lever 23 can push the battery towards the return conveyor belt 7. When the proximity sensor 24 detects the third motor 22, the second motor 20 shuts off, and the battery is moved onto the return conveyor belt 7. Then the third motor 22 drives the lever 23 to rotate 180 degrees. At this time, the lever 23 returns to its initial position.

[0039] Once all four sides of the battery pass the comparison, the battery is deemed qualified after water washing. The controller then directly activates the third motor 22, which drives the lever 23 to rotate 180 degrees. Next, the controller activates the second motor 20, which drives the lead screw 19 to rotate forward. This causes the slider 21, the third motor 22, and the lever 23 to move to the left. During this leftward movement, the straight section of the lever 23 pushes the battery towards the discharge conveyor belt 6. When the proximity sensor 24 no longer detects the third motor 22, the second motor 20 shuts off. At this point, the battery is moved onto the discharge conveyor belt 6.

[0040] Then the controller starts the second motor 20, which drives the lead screw 19 to rotate in the opposite direction, thereby causing the slider 21, the third motor 22 and the lever 23 to move to the right. When the proximity sensor 24 detects the third motor 22, the second motor 20 is turned off.

[0041] Then the third motor 22 drives the lever 23 to rotate 180 degrees. At this time, the lever 23 returns to its initial position.

[0042] Example 2: Based on Example 1, referring to... Figure 1 As shown, two stop bars 4 are fixed at the upper end of the turntable 2, and the ends of the stop bars 4 on the same side are machined with guide slopes 5.

[0043] As the push rod 10 pushes the battery towards the upper end of the turntable 2, one end of the stop rod 4 with the guide ramp 5 faces the feeding conveyor belt 8. After the battery moves to the upper end of the turntable 2, it is positioned between the two stop rods 4. Under the guidance of the guide ramp 5, the battery moves easily between the two stop rods 4. After the battery is positioned between the two stop rods 4, the first motor 3 drives the turntable 2 to rotate counterclockwise, causing the industrial camera 16 to capture images of the side of the battery.

[0044] The battery is limited by two levers 4, which can improve the stability of the battery, ensure the relative position of the industrial camera 16 and the battery, improve the consistency of the side image acquisition of the battery, and thus improve the comparison accuracy.

[0045] In this embodiment, when one side of the battery fails to match, the first motor 3 drives the turntable 2 and the battery to return to their original positions. Then, the controller causes the first motor 3 to rotate the turntable 2 counterclockwise by 90 degrees, so that the end of the stop bar 4 with the guide slope 5 faces the return conveyor belt 7. Then, the lever 23 is used to push the battery between the two stop bars 4 toward the return conveyor belt 7.

[0046] Since the industrial camera 16 can capture an image of one side of the battery when it enters between the two baffles 4 without the turntable 2 rotating, the battery remains stationary after the industrial camera 16 captures and matches an image of the fourth side of the battery. At this point, the baffle 4 with its inclined end faces the discharge conveyor belt 6, and the battery can be directly pushed onto the discharge conveyor belt 6 using the lever 23.

[0047] After the battery enters the discharge conveyor belt 6, the lever 23 returns to its initial position. Then, the first motor 3 drives the turntable 2 to rotate and reset, which facilitates the detection of the next battery.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
