TECHNICAL FIELD
[0001] The utility model relates to lithium battery detection technical field especially relates to a device for lithium battery puncture detection. BACKGROUND
[0002] In the lithium battery detection technical field, puncture detection as an important quality evaluation method is crucial for ensuring the safety and performance of lithium batteries. However, the widely used lithium battery puncture detection equipment has many shortcomings, which seriously affects the accuracy and efficiency of detection.
[0003] First, the existing lithium battery puncture detection device is usually equipped with a fixed-size battery detection platform, which limits its adaptability to different sizes of batteries. Since lithium batteries come in various sizes, the limitations of the fixed-size detection platform are particularly evident. It cannot flexibly adapt to batteries of various sizes, greatly reducing the universality of detection and the practicality of the equipment. At the same time, most of the detection equipment on the market can only detect batteries one by one, which undoubtedly reduces the detection efficiency and increases the time and labor costs. In industrial production, there is an urgent need for equipment that can detect multiple batteries simultaneously, which is of great significance to improving production efficiency and ensuring product quality.
[0004] Second, during the puncture detection process, the existing equipment often cannot ensure consistent force and depth of each puncture. This uneven puncture operation can lead to inaccurate detection variables, affecting the accurate assessment of lithium battery performance and safety. This inaccuracy not only may mislead production decisions, but also may pose potential safety risks.
[0005] Therefore, the existing lithium battery puncture detection equipment has significant shortcomings in adaptability, efficiency and accuracy, and technicians in the field urgently need a new detection device to overcome these problems. INVENTION CONTENTS

[0024] Detection platform 2: Located at the front end of the base 1, it is the main area for placing and detecting lithium batteries. The detection platform includes a horizontal sliding cylinder 21 and a loading platform 22.
[0025] Horizontal sliding cylinder 21: controls the forward and backward movement of the loading platform 22 to achieve precise positioning of the lithium battery. To meet the needs of efficient detection, two horizontal sliding cylinders 21 can be configured to improve the detection efficiency of the equipment.

Designed for flexibility and versatility, the loading platform can be changed based on the size of the battery being inspected, ensuring that lithium-ion batteries of all sizes can be securely placed on the loading platform.
[0027] Stand 4: firmly mounted on the base, opposite to the detection platform 2, to provide stable support for the puncture mechanism 3.
[0028] The puncture mechanism 3 is the core part of the device and is responsible for performing the puncture action of the lithium battery. It includes a slide rail 31, a puncture device 32, a puncture needle 33 and a vertical sliding cylinder 34.
[0029] Slide rail 31: It is arranged on the side of the stand 4 and faces the detection platform 2. The slide rail 31 is designed with a groove for quickly installing and positioning the puncture device 32.
[0030] Puncture device 32 is L-shaped with a rear flange that mates with the grooves in rail 31, allowing it to slide smoothly along the rail. The number of puncture devices 32 can range from one to three, depending on actual needs, to meet the requirements of different testing tasks.

[0036] Next, the vertical sliding cylinder 34 is started to precisely control the puncture needle 33 to perform puncture detection on the lithium battery.
[0037] During the entire process, multiple lithium batteries can be tested simultaneously as needed to improve detection efficiency. At the same time, since the puncture force and depth are precisely controlled by the vertical sliding cylinder 34, the results of each puncture are highly consistent and accurate.
