[0026] The terms used in the implementation manners part of the present application are only used to explain the specific embodiments of the present application, rather than intended to limit the present application. The implementation manners of the embodiments of the present application will be described in detail below with reference to the drawings.
[0027] In this embodiment, a horizontal thickness measuring mechanism is specifically provided, aiming to efficiently and accurately measure the thickness of the electrode tabs of the battery cells, and integrating the function of automatically clamping 140 for charging and discharging to simplify the operation process and improve production efficiency.
[0028] As Figure 1 shown, the horizontal thickness measuring mechanism in this embodiment mainly consists of four major parts: a movable detection module 110, a fixed detection module 120, a mounting frame 130, and an automatic charging and discharging clamp 140. The overall structure is designed compactly, facilitating integration into the battery production line.
[0029] Among them, the activity detection module 110 is arranged on the left side of the mounting bracket 130, the fixed detection module 120 is arranged on the right side of the mounting bracket 130, and the automatic charging and discharging clamp 140 is arranged on one side of the fixed detection module 120 for clamping the electrode tab of the battery cell. The activity detection module 110 includes an activity pressing plate 111, an activity seat 112, a slide rail 113 and a lateral movement driving device 114. The activity pressing plate 111 is installed on the side of the activity seat 112 close to the fixed detection module 120. The activity seat 112 is installed on the slide rail 113, and the lateral movement driving device 114 drives the activity seat 112 to drive the activity pressing plate 111 to move horizontally along the slide rail 113. The fixed detection module 120 includes a fixed pressing plate 121 and a pressure sensor 122. The pressure sensor 122 is arranged on one side of the fixed plate. As Figure 3 shown, a first pressing plate replacement roller device 115 is arranged on one side of the activity pressing plate 111. The first pressing plate replacement roller device 115 includes a first mounting seat 115a and a plurality of first rollers 115b arranged side by side on the first mounting seat 115a. The activity pressing plate 111 is a key component for performing measurement tasks. Considering measurement accuracy and durability, a marble plate is used as the material of the activity pressing plate 111 in this embodiment. However, due to the large weight of the marble plate, traditional installation methods are often cumbersome and inconvenient. For this reason, the present invention designs an innovative first pressing plate replacement roller device 115 on one side of the activity pressing plate 111 to simplify the installation and replacement process of the marble plate pressing plate.
[0030] Installation process: Place the marble plate pressing plate above the first roller 115b device. Utilizing the rolling property of the roller, push the marble plate along the roller to the installation position of the activity seat 112 by manpower or a simple auxiliary tool (such as a trolley on the slide rail 113). During this process, the rolling of the roller greatly reduces the friction force and the required manpower when the marble plate moves, making the installation process easy and fast.
[0031] As Figure 3 shown, in this embodiment, a second pressing plate replacement roller device 123 is arranged on one side of the fixed pressing plate 121. The second pressing plate replacement roller device 123 includes a second mounting seat 123a and a plurality of second rollers 123b arranged side by side on the second mounting seat 123a. The function of the second pressing plate replacement roller device 123 is the same as that of the first pressing plate replacement roller device 115.
[0032] As Figure 1 shown, in this embodiment, in order to reduce the pressing gap and improve the accuracy and stability of the test, a nitrogen spring is connected to the activity seat 112 in the present invention. The nitrogen spring utilizes the compressibility of nitrogen to provide stable elastic force, and can automatically adjust the distance between the activity pressing plate 111 and the fixed pressing plate 121 during the test process to ensure that the pressing gap between the two always remains consistent. This design not only improves the accuracy of the test, but also effectively extends the service life of the equipment.
[0033] As Figure 1 shown in this embodiment, in the transfer driving device, a high-precision servo electric cylinder is adopted to achieve the precise movement of the movable platen 111. To further improve the stability of the servo electric cylinder, a wire rope 116 structure is added between the servo electric cylinder and the mounting bracket 130 in the present invention. These wire ropes 116 are respectively arranged above and below the servo electric cylinder to form a stable support and limiting effect. One end of each wire rope 116 is firmly connected to the servo electric cylinder, and the other end is connected to the mounting bracket 130. This design effectively prevents the servo electric cylinder from shaking or shifting during high-speed movement or under a large load, ensuring the smooth progress of the test process.
[0034] As Figure 3 shown in this embodiment, in order to ensure that the battery cell is always at the center position of the fixed platen 121 during the test, a battery cell elevation plate 124 is added to the side of the fixed platen 121 close to the movable platen 111 in the present invention. The battery cell elevation plate 124 is designed to match the shape of the battery cell, and can accurately support the bottom of the battery cell 400, making it parallel and centered with the fixed platen 121. This design improves the accuracy of the test.
[0035] In this embodiment, in order to monitor the pick-up and placement status of the battery cell in real time, an opposed photoelectric sensor is added inside the fixed platen 121 in the present invention. The opposed photoelectric sensor detects whether the battery cell has been taken away by emitting and receiving infrared light. When the battery cell is taken away, the opposed photoelectric sensor will immediately send a signal to the control system, and the control system will then stop the test or perform the next operation. This design improves the safety and automation level of the equipment.
[0036] As Figure 1 shown in this embodiment, in order to deal with possible abnormal situations (such as battery cell short circuit, overheating, etc.) during the test, a fire protection device 150 is added in the present invention. The device includes a fire protection pushing mechanism 151 and a combustion chamber 152. The fire protection pushing mechanism 151 is arranged on one side of the fixed platen 121 and is used to quickly push the battery cell into the combustion chamber 152 when an abnormal situation is detected; the combustion chamber 152 is arranged on one side of the fire protection pushing mechanism 151 and is used to safely handle the abnormal battery cell. This design ensures the quick response and effective handling ability of the equipment in case of an emergency.
[0037] As Figure 3As shown, in this embodiment, the automatic charge and discharge clamp 140 is a key component for clamping the electrode tabs of the battery cell, and its performance and stability are crucial for the testing process. The automatic charge and discharge clamp 140 in the present invention includes clamping pieces 141 and a clamp opening and closing motor 142 for driving the clamping pieces to clamp the electrode tabs of the battery cell. The clamping pieces are made of materials with high strength and high wear resistance to ensure that they can firmly clamp the electrode tabs of the battery cell; the clamp opening and closing motor 142 is controlled by a high-precision servo motor or a stepper motor to ensure the rapidity, accuracy, and reliability of the clamping action.
[0038] As Figure 1 shown, in this embodiment, for the convenience of equipment installation, maintenance, and transportation, the present invention adds a lifting ring 160 to the top of the mounting frame 130. The lifting ring 160 is made of high-strength materials and can withstand a large pulling force to ensure the stability and safety of the equipment during the lifting process. This design makes the movement and installation of the equipment more convenient and efficient.
