[0002] Against the backdrop of the booming development of the new energy battery industry, battery safety, stability, and production efficiency have become core concerns for the industry. As a key protective component of the battery, the quality of the battery casing directly affects the overall performance and safety of the battery. Therefore, quality control of the battery casing is extremely important. In the production process of the battery casing, the stamping process is an indispensable key link. Stamping can give the battery casing a specific shape and size to meet the needs of subsequent battery assembly. After the battery casing is stamped, various defects may occur due to mold wear, abnormal stamping parameters, and raw material defects. Therefore, in order to ensure the quality of the battery casing, stamping inspection is carried out after the battery casing is stamped.

[0003] Existing battery casing stamping inspection devices have low levels of intelligence and still rely mainly on manual inspection. This leads to operator fatigue after long hours of work, potentially resulting in missed inspections (such as ignoring tiny cracks on the inner wall of the casing) or misjudgments (such as mistaking normal textures for defects). In addition, loading and unloading the battery casings to be inspected is inconvenient, and the battery casings are prone to shifting during placement, thus reducing the efficiency of battery casing inspection. To solve the above problems, a battery casing stamping inspection device has been proposed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-4 The shown battery casing stamping inspection device includes a base 1 and a fixing frame 2. The fixing frame 2 is mounted on the base 1. A hydraulic cylinder 3 is provided on the top of the fixing frame 2. The piston rod of the hydraulic cylinder 3 passes through the fixing frame 2 and is equipped with an inspection device 4. A sliding module 6 is installed at a symmetrical position on the surface of the base 1. A connecting plate 5 is installed on the sliding module 6. A snap-fit ​​mechanism 7 is provided on the surface of the connecting plate 5. The snap-fit ​​mechanism 7 is used to snap-fit ​​and position the battery casing. In use, the sliding module 6 first moves the connecting plate 5 to a suitable position, and the battery casing is placed on the snap-fit ​​mechanism 7 of the connecting plate 5. The snap-fit ​​mechanism 7 snaps and positions the battery casing. Then the sliding module 6 is reset, and the hydraulic cylinder 3 drives the detection device 4 to descend and detect the battery casing. The beneficial effect is that the detection device 4 driven by the hydraulic cylinder 3 realizes mechanized detection, replacing manual labor and reducing errors. The sliding module 6, together with the snap-fit ​​mechanism 7, facilitates loading and unloading, and can stably position the casing, avoiding displacement of the casing during detection and improving detection efficiency and stability.

[0018] The detection device 4 includes a mounting plate 41, the upper surface of which is fixedly connected to the piston rod of the hydraulic cylinder 3, and the two ends of the mounting plate 41 are slidably connected to the fixing frame 2. The lower surface of the connecting plate 5 is equipped with detectors 42 that are used to detect the battery casing after it is stamped. During testing, the piston rod of the hydraulic cylinder 3 drives the mounting plate 41 to move downward. The two ends of the mounting plate 41 slide along the fixed frame 2. The detectors 42, which are evenly distributed below, simultaneously perform part inspections on the battery casing. The sliding of the mounting plate 41 makes the movement of the inspection device 4 more stable. The simultaneous operation of multiple detectors 42 can speed up the inspection of the battery casing and improve the efficiency of the inspection. Furthermore, the detectors 42 replace the manual inspection operation, reducing the occurrence of missed inspections (such as small cracks in the inner wall of the casing) and misjudgments (such as mistaking normal textures for defects). This effectively ensures the quality inspection accuracy of the battery casing, thereby ensuring the overall performance and safety of the battery. The controller installed on one side of the mounting bracket 2 is electrically connected to the detector 42. The detector 42 mainly consists of a core detection module, a signal processing unit, and a data comparison and judgment unit. The detector 42 scans and detects the surface and interior of the battery casing to identify defects that may occur during the stamping process (such as cracks, deformation, uneven thickness, etc.). Specifically, when the detection device 4 is lowered to a suitable position under the drive of the hydraulic cylinder 3, the core detection module will emit specific detection signals (such as optical signals, ultrasonic signals, etc.). After the signal contacts the casing, it will be reflected or transmitted. The signal processing unit receives these feedback signals and converts them into electrical signals. The data comparison and judgment unit compares the processed signal with the preset qualified standard parameters to determine whether there are defects in the casing.

[0019] The detection device 4 also includes a slider 43 and a slide groove 44. The slide groove 44 is opened on the inner side wall of the fixed frame 2. The slider 43 is fixed at both ends of the mounting plate 41 and is slidably connected within the slide groove 44. When the mounting plate 41 moves, the sliders 43 at both ends slide within the grooves 44 on the inner sidewall of the fixing frame 2. This design makes the lifting and lowering of the mounting plate 41 smoother, avoiding jamming or displacement, ensuring that the detection device 4 can accurately align with the battery casing, and improving the stability and reliability of the detection.

[0020] The snap-fit ​​mechanism 7 includes a fixing plate 71, which is inserted into the surface of the connecting plate 5 from left to right. A slot 72 is provided at the center of the fixing plate 71, and a positioning component 73 is provided in the inner cavity of the slot 72. When placing the battery casing, it is inserted into the corresponding slot 72 of the fixing plate 71, and the positioning component 73 in the slot 72 further secures the casing. This structure makes the positioning of the battery casing more convenient and accurate, can adapt to casings of different sizes, and at the same time, the positioning component 73 enhances the fixing effect, prevents the casing from shaking during the testing process, and ensures the accuracy of the test data.

[0021] The number of fixed plates 71 is equal to the number of detectors 42, and the position of each fixed plate 71 corresponds vertically to the position of the detector 42; Each fixing plate 71 is vertically aligned with the corresponding detector 42. When the housing is placed on the fixing plate 71, the detector 42 can directly detect the corresponding position of the housing. This one-to-one correspondence design ensures the targeting and accuracy of the detection, avoids misalignment between the detector 42 and the housing leading to missed detection or false detection, and improves the accuracy and efficiency of the detection.

[0022] The snap-fit ​​mechanism 7 also includes a positioning post 74 and a positioning hole 75. The positioning post 74 is fixed around the bottom of the fixing plate 71, and the positioning hole 75 is opened around the surface of the connecting plate 5. The lower end of the positioning post 74 is inserted into the positioning hole 75. When installing the fixing plate 71, the positioning pin 74 is inserted into the positioning hole 75 of the connecting plate 5 to achieve quick installation and positioning of the fixing plate 71. This structure facilitates the disassembly and replacement of the fixing plate 71, and the fixed shape can be made according to actual needs to ensure the stability of the fixing plate 71 after installation and prevent the fixing plate 71 from shifting during testing and affecting the testing effect.

[0023] The positioning component 73 includes a sliding sleeve 731, which is embedded in two symmetrical sides of a fixed plate 71. A sliding rod 732 is slidably connected inside the sliding sleeve 731. A locking block 733 is fixedly connected to one end of the sliding rod 732. A protective pad 734 is attached to one side of the locking block 733. A limiting block 735 is fixedly connected to the other end of the sliding rod 732. A spring 736 is fixedly connected to the side of the limiting block 735 facing the fixed plate 71. The spring 736 is sleeved on the surface of the sliding rod 732. When the battery casing is placed into the slot 72, the locking block 733 is pressed, the slide rod 732 slides within the sliding sleeve 731, and the spring 736 is compressed. The elastic force of the spring 736 makes the locking block 733 fit tightly against the battery casing. The protective pad 734 prevents the casing from being pinched by the locking block 733 and enhances the friction. This positioning method can adapt to the size error of the casing and firmly fix casings of different specifications. It not only ensures the fixing effect but also avoids damage to the casing, improving the versatility of the device and the protection of the battery casing.

[0024] When using the stamping inspection device 4 for the battery casing, firstly operate the sliding module 6 to move the connecting plate 5 to a suitable position for easy loading and unloading. Then, according to the specifications of the battery casing to be inspected, select the matching fixing plate 71, align the positioning pins 74 around the bottom of the fixing plate 71 with the positioning holes 75 on the surface of the connecting plate 5 and insert them to complete the quick installation and positioning of the fixing plate 71. Subsequently, place the battery casing into the slot 72 in the center of the fixing plate 71. During the placement process, the casing presses the locking blocks 733 on both sides of the slot 72, causing the slide rod 732 to slide in the sliding sleeve 731. The spring 736 is compressed accordingly. Using the elastic force of the spring 736, the locking block 733 will tightly fit the casing. The protective pad 734 on one side of the locking block 733 can not only prevent the casing from being pinched, but also enhance the friction and achieve stable positioning of the casing. At the same time, this positioning method can adapt to the size error of the casing and is suitable for casings of different specifications. After the housing is placed, the sliding module 6 drives the connecting plate 5 to reset, so that the battery housing is directly below the detection device 4, and each fixed plate 71 is vertically aligned with the corresponding detector 42 above it. Then, the piston rod of the hydraulic cylinder 3 is extended, which drives the mounting plate 41 to move down. The sliders 43 at both ends of the mounting plate 41 slide in the grooves 44 on the inner side wall of the fixed frame 2 to ensure that the mounting plate 41 moves up and down smoothly and does not deviate. As the mounting plate 41 moves down, the detectors 42 distributed at equal intervals on its lower surface descend synchronously to the appropriate detection position. At this time, the detectors 42 start to work and emit specific detection signals such as optical signals and ultrasonic signals through the core detection module. After the signal comes into contact with the housing, it is reflected or transmitted. The signal processing unit receives the feedback signal and converts it into an electrical signal. Then, the data comparison and judgment unit compares the processed data with the preset qualified standard parameters to determine whether there are defects such as cracks or deformations in the housing. Throughout the detection process, the controller and the detector 42 are electrically connected to transmit and process the detection information in real time. After the test is completed, the piston rod of the hydraulic cylinder 3 retracts, causing the mounting plate 41 and detector 42 to rise and reset. The sliding module 6 then moves the connecting plate 5 to the material picking position, and the staff takes out the tested battery casing, completing one test process.
