Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a detection device for the internal mesh of a battery. Background Technology

[0002] Maintenance-free batteries do not require replenishment of electrolyte later on, which is environmentally friendly. The battery's internal oxygen recombination reaction is controlled by a venting valve. Therefore, the amount of acid participating in the reaction inside the battery must be properly controlled. During the later stages of the charging and formation phase, a float charge of 15V or higher is required to remove excess acid from the battery through an acid extraction tube. To prevent damage to the internal separators by the acid extraction tube, current practices place acid-resistant mesh on the surface of the separators at the top of the electrode group. Existing technology uses an automatic mesh placement machine for mesh placement; however, mesh can easily be missed during this process. This can also lead to separator damage during acid extraction, increasing the battery defect rate. Therefore, it is necessary to inspect batteries that have had mesh placed and to manually place any batteries with missing mesh. Utility Model Content

[0003] The main objective of this invention is to provide a battery internal mesh detection device that can detect the mesh inside the battery, sort out batteries with missing mesh, and reduce the battery defect rate.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A detection device for internal mesh of a battery includes a tray, with a second fixed plate and a third fixed plate fixed to the front and rear sides of the upper end of the tray, respectively. A lifting plate is slidably arranged vertically on the tray to the left of the second fixed plate, and the lower end of the lifting plate is connected to a drive unit at the lower end of the tray. A swing plate is arranged on the tray to the left of the lifting plate, and a motor is fixed to the lower end of the tray. The output shaft of the motor is fixedly connected to the left end of the swing plate. A first fixed plate is fixed to the upper end of the tray to the left of the third fixed plate. After the right end of the swing plate swings to the rear, the right end of the swing plate can enter between the first fixed plate and the third fixed plate. A first gap is provided between the first fixed plate and the third fixed plate. A second gap is provided between the swing plate and the lifting plate. The first gap is located to the left rear of the second gap. A third gap is provided between the lifting plate and the second fixed plate. The rear ends of the swing plate, the lifting plate, and the second fixed plate are flush. The front ends of the first fixed plate and the third fixed plate are flush. A pushing component is fixed to the upper end of the tray behind the first fixed plate and the third fixed plate. A detection unit is arranged on the tray, and the detection unit is located above the second fixed plate and the third fixed plate.

[0005] Specifically, the drive unit includes a lower bracket fixed to the lower end of the support plate, a lower cylinder fixed on the lower bracket, and the upper end of the lower cylinder fixedly connected to the lower end of the lifting plate.

[0006] Specifically, the lower cylinder is connected to the lower directional valve via an air circuit, and the lower directional valve is electrically connected to the controller.

[0007] Specifically, the motor is a brake motor, and the motor is electrically connected to the controller.

[0008] Specifically, the detection unit includes an industrial camera, which is located above the space between the second and third fixed plates. An upper bracket is fixed on the support plate, and the industrial camera is fixed on the upper bracket. The industrial camera is electrically connected to the controller.

[0009] Specifically, the pushing assembly includes a multi-stage cylinder fixed to the upper end of the support plate. The multi-stage cylinder is arranged horizontally, and an elongated groove is opened on the telescopic end of the multi-stage cylinder. One end of the push rod is rotatably set in the elongated groove through a rotating rod. One end of the push rod in the elongated groove is connected to the telescopic end of the multi-stage cylinder through a torsion spring. A limit rod is fixed on the telescopic end of the multi-stage cylinder on the right side of the push rod. The push rod contacts the limit rod and is perpendicular to the multi-stage cylinder.

[0010] Specifically, the multi-stage cylinder is connected to the air circuit of the upper reversing valve, and the upper reversing valve is electrically connected to the controller.

[0011] Specifically, a photoelectric sensor is fixed to the upper end of the second fixing plate on the right side of the upper bracket, and the photoelectric sensor is electrically connected to the controller.

[0012] Specifically, both the right end of the second fixing plate and the right end of the third fixing plate are machined with guide slopes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device automatically captures images of the internal mesh of batteries using an industrial camera. The controller performs image preprocessing, feature extraction, and template comparison, requiring no manual intervention. Qualified batteries are moved to a designated position by a pusher, facilitating gripping by a robotic arm for subsequent cover installation. Unqualified batteries are automatically guided to the waste area via the coordinated action of a swing plate and a lifting plate. The entire process integrates detection and sorting, significantly improving production efficiency and consistency.

[0014] 2. This device optimizes the battery entry and positioning path, reducing the risk of jamming. The rational layout of the first, second, and third gaps, combined with the flush design of the swing plate, lifting plate, and multiple fixed plates, ensures the stable posture of the battery during detection and sorting. This reduces the need for manual adjustments and improves operational smoothness and reliability.

[0015] 3. The controller coordinates the drive unit, motor, and detection unit to achieve seamless operation. Photoelectric sensors further enhance intelligence; automatic detection is triggered upon battery arrival, avoiding delays, enabling precise control, and reducing human error.

[0016] 4. The brake motor prevents the swing plate from rotating unexpectedly, ensuring the stability of the sorting process; the limit rod restricts the range of motion of the push rod, and combined with the torsion spring's energy storage and restoration mechanism, it avoids component overload or failure, improving the durability of the device and production safety.

[0017] 5. All components are integrated on the pallet, resulting in a compact structure that is easy to install and debug; the modular design of the pneumatic components and electrical control system simplifies the maintenance and upgrade process and adapts to different production line layout requirements.

[0025] 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.

[0026] like Figure 1 As shown, during the production process of battery 18, a mesh 19 needs to be placed on the top of the cluster within the cell of battery 18. The mesh 19 is located between the positive busbar and the negative busbar.

[0027] Example 1: Refer to Figures 2-6As shown, a detection device for the internal mesh of a battery includes a tray 1. A second fixing plate 10 and a third fixing plate 11 are fixed on the front and rear sides of the upper end of the tray 1, respectively. A lifting plate 4 is slidably arranged on the left side of the tray 1 in the vertical direction. The lower end of the lifting plate 4 is connected to the driving unit at the lower end of the tray 1.

[0028] The drive unit includes a lower bracket 2 fixed to the lower end of the support plate 1, a lower cylinder 3 fixed on the lower bracket 2, and the upper end of the lower cylinder 3 fixedly connected to the lower end of the lifting plate 4.

[0029] The lower cylinder 3 is connected to the air circuit of the lower directional valve, and the lower directional valve is electrically connected to the controller.

[0030] A swing plate 8 is installed on the support plate 1 on the left side of the lifting plate 4. A motor 5 is fixed to the lower end of the support plate 1. The motor 5 is a brake motor and is electrically connected to the controller. The output shaft of the motor 5 is fixedly connected to the left end of the swing plate 8.

[0031] The first fixed plate 9 is fixed to the upper end of the support plate 1 on the left side of the third fixed plate 11. After the right end of the swing plate 8 swings to the rear, the right end of the swing plate 8 can enter between the first fixed plate 9 and the third fixed plate 11.

[0032] A first gap is provided between the first fixed plate 9 and the third fixed plate 11, a second gap is provided between the swing plate 8 and the lifting plate 4, the first gap is located on the left rear side of the second gap, and a third gap is provided between the lifting plate 4 and the second fixed plate 10.

[0033] The rear ends of the swing plate 8, the lifting plate 4, and the second fixed plate 10 are flush, while the front ends of the first fixed plate 9 and the third fixed plate 11 are flush.

[0034] Guide slopes 12 are machined on the right ends of both the second fixing plate 10 and the third fixing plate 11. By setting the guide slopes 12, it is convenient for the battery 18 to enter between the second fixing plate 10 and the third fixing plate 11.

[0035] Pushing components are fixed to the upper end of the support plate 1 on the rear side of the first fixed plate 9 and the third fixed plate 11. A detection unit is provided on the support plate 1, and the detection unit is located above the second fixed plate 10 and the third fixed plate 11.

[0036] The detection unit includes an industrial camera 7, which is located above the space between the second fixed plate 10 and the third fixed plate 11. An upper bracket 6 is fixed on the support plate 1, and the industrial camera 7 is fixed on the upper bracket 6. The industrial camera 7 is electrically connected to the controller.

[0037] The pushing assembly includes a multi-stage cylinder 13 fixed to the upper end of the support plate 1. The multi-stage cylinder 13 is arranged horizontally. A long groove 14 is opened on the telescopic end of the multi-stage cylinder 13. One end of the push rod 16 is rotatably disposed in the long groove 14 through the rotating rod 15. One end of the push rod 16 in the long groove 14 is connected to the telescopic end of the multi-stage cylinder 13 through a torsion spring. A limit rod 17 is fixed on the telescopic end of the multi-stage cylinder 13 on the right side of the push rod 16. The push rod 16 contacts the limit rod 17 and is perpendicular to the multi-stage cylinder 13.

[0038] The multi-stage cylinder 13 is connected to the air circuit of the upper reversing valve, and the upper reversing valve is electrically connected to the controller.

[0039] During the process of the battery 18 being conveyed between the second fixed plate 10 and the third fixed plate 11, after the battery 18 contacts the push rod 16, as the battery 18 moves continuously to the left, the battery 18 causes the front end of the push rod 16 to swing to the left, and the torsion spring stores force. When the battery 18 is located below the industrial camera 7, the battery 18 separates from the push rod 16. Under the elastic action of the torsion spring, the push rod 16 returns to its original position. After the push rod 16 returns to its original position, it is blocked by the limit rod 17. The push rod 16 is perpendicular to the multi-stage cylinder 13.

[0040] After the battery 18 is positioned below the industrial camera 7, the industrial camera 7 is activated. The industrial camera 7 acquires an image of the inner mesh 19 at the top of the battery 18. The industrial camera 7 obtains an optical image of the inner mesh 19 at the top of the battery 18 through its lens and transmits the analog electrical signal to the controller via a data interface. After receiving the data, the controller converts the signal into a digital signal using an analog-to-digital converter and stores it in its memory. Then, the controller preprocesses the received image data (e.g., noise reduction and enhancement), followed by feature extraction and target detection. The controller compares the acquired image with a preset template or algorithm to identify differences or similar features. If the inner mesh 19 at the top of the battery 18 is not missing, the comparison passes. After the comparison is successful, the controller activates the multi-stage cylinder 13 via the upper reversing valve. The extension end of the multi-stage cylinder 13 drives the push rod 16 to move to the left. During the movement of the push rod 16 to the left, it drives the battery 18 to move to the left. When the extension end of the multi-stage cylinder 13 reaches the retraction stop, the battery 18 is located between the swing plate 8 and the first fixed plate 9. Then, the multi-stage cylinder 13 resets the push rod 16. Subsequently, the robot arm picks up the battery 18 between the swing plate 8 and the first fixed plate 9 and moves it to the top cover station to install a cover on the top of the battery 18.

[0041] The industrial camera 7 acquires an optical image of the inner mesh 19 at the upper end of the battery 18 through its lens for comparison. If the comparison fails, the inner mesh 19 at the upper end of the battery 18 is missing. Then, the controller starts the motor 5, which drives the swing plate 8 to swing. After the right end of the swing plate 8 is within the first interval, the motor 5 is turned off. Then, the controller starts the lower cylinder 3 through the lower reversing valve, causing the lifting plate 4 to descend. After the lifting plate 4 descends, the upper end of the lifting plate 4 is flush with the upper end of the support plate 1. Then, the controller activates the multi-stage cylinder 13 via the upper reversing valve. The extension end of the multi-stage cylinder 13 pushes the battery 18 to the left via the push rod 16. When the battery 18 contacts the inclined swing plate 8, under the guidance of the swing plate 8, the battery 18 moves forward on the support plate 1. At this time, the lifting plate 4 cannot block the battery 18. When the extension end of the multi-stage cylinder 13 reaches the retraction stop point, the motor 5 is activated. The motor 5 drives the swing plate 8 to reset. During the swing reset process, the battery 18 continues to move forward on the upper end of the support plate 1. During the swing reset process, the push rod 16 blocks the battery 18, preventing the battery 18 from moving to the right.

[0042] After the swing plate 8 is reset, the battery 18 is located in front of the swing plate 8 and the lifting plate 4. Then the controller starts the lower cylinder 3 and the multi-stage cylinder 13 through the lower reversing valve and the upper reversing valve, so that the lifting plate 4 and the push rod 16 are restored.

[0043] Example 2: Based on Example 1, referring to... Figures 3-5 As shown, a photoelectric sensor 20 is fixed to the upper end of the second fixing plate 10 on the right side of the upper bracket 6, and the photoelectric sensor 20 is electrically connected to the controller.

[0044] After the battery 18 is positioned between the second fixed plate 10 and the third fixed plate 11 by setting up the photoelectric sensor 20, the photoelectric sensor 20 can detect the battery 18. The photoelectric sensor 20 sends a signal to the controller, and the controller starts the industrial camera 7 and acquires the image of the upper end of the battery 18, which can automatically start the detection.

[0045] 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.
