[0002] Lithium-ion batteries, as a highly efficient and environmentally friendly energy storage device, are widely used in electric vehicles, portable electronic devices, and other fields. PTC elements in lithium-ion batteries play an overcurrent protection role; when the battery current is too high, the resistance of the PTC element increases rapidly, thereby limiting the current and preventing the battery from overheating or being damaged.

[0003] Traditional manual assembly and welding methods are increasingly showing their limitations when facing large-scale lithium battery production. Manual assembly and welding present significant challenges in terms of precision and quality control. The assembly process of lithium batteries involves the precise matching of multiple precision components. However, manual operation is easily affected by various human factors such as operator skill level, fatigue, and working environment, often leading to unstable assembly precision, which in turn affects the overall performance and safety of lithium batteries. At the same time, welding is a critical step in lithium battery manufacturing, and its quality directly affects the reliability of the battery's electrical connections and its long service life. Problems such as weak welds, incomplete soldering, or overheating that may occur during manual welding can all pose potential safety hazards to lithium batteries. Utility Model Content

[0015] like Figures 1 to 3 As shown, a novel automated assembly and welding device for PTCs used in low-temperature lithium batteries includes a first base plate 100 and a second base plate 200 arranged adjacent to each other. The first base plate 100 has a base 103 on its top, and a storage box 105 is mounted on the top of the base 103 via a mounting bracket 104. Multiple PTC bodies 109 are stored in the storage box 105. The second base plate 200 has a conveyor belt 201 on its top, and multiple substrates 300 are placed on the conveyor belt 201. The top of each substrate 300 is connected to the PTC bodies. The 109-phase-compatible welding groove 301, the transmission roller end of the conveyor belt 201 is equipped with a motor 202, the top of the second base plate 200 is provided with a support column 203 on the side away from the first base plate 100, the top of the support column 203 is fixedly provided with a connecting plate 204, the bottom of the connecting plate 204 is provided with an electric welding machine 205, the bottom of the first base plate 100 is provided with an automatic feeding component that can feed the PTC body 109, and the top of the conveyor belt 201 is provided with a limiting component for fixing the substrate 300.

[0016] In this embodiment, the automatic feeding assembly includes a side plate 101 located on the top of the first base plate 100, a hydraulic rod 102 on the side wall of the side plate 101, a push block 108 fixedly provided at the output end of the hydraulic rod 102, and a discharge slot 110 adapted to the PTC body 109 is provided on the side wall of the mounting frame 104.

[0017] The hydraulic rod 102 pushes the push block 108 to push the PTC body 109 in the storage box 105 out through the discharge groove 110, so that it falls into the welding groove 301 on the top of the substrate 300. The automatic feeding component can continuously and quickly complete the feeding of the PTC body 109, which greatly improves the production efficiency.

[0018] In this embodiment, the storage box 105 is provided with a lid 106 on the top, and the side wall of the lid 106 is provided with a plurality of anti-slip strips 107. The storage box 105 is made of transparent material.

[0019] The storage box 105 is made of transparent material, making it easy to observe the quantity and status of the PTC body 109. The anti-slip strip 107 on the side wall of the box cover 106 can enhance the anti-slip properties and prevent the box cover 106 from accidentally slipping off.

[0020] In this embodiment, the limiting component includes mounting plates 206 disposed on both sides of the conveyor belt 201. The sidewall of the mounting plate 206 is provided with a clamping plate 207. The sidewall of the clamping plate 207 is in contact with the sidewall of the base plate 300.

The bottom of the fixing plate 303 is provided with a plurality of limiting rods 304. The limiting rods 304 abut against the front end of the base plate 300.

[0021] The clamping plate 207 contacts the side wall of the substrate 300 to prevent the substrate from shifting during the transfer process. At the same time, the telescopic rod 302 drives the fixing plate 303 and the limiting rod 304 to move. The limiting rod 304 abuts against the front end of the substrate 300 to further fix the position of the substrate, so that the substrate 300 moves along the specified path, which enhances the stability and reliability of the device, improves the accuracy of the welding, and enhances the welding effect.

[0022] In this embodiment, the surfaces of the clamping plate 207 and the limiting rod 304 that are in contact with the substrate 300 are provided with a wear-resistant layer.

[0024] Working process and principle: When using this device, firstly, the PTC body 109 is placed in the storage box 105 and the box cover 106 is closed. Then, multiple substrates 300 are placed on the conveyor belt 201. Each substrate 300 has a welding groove 301 on its top that is compatible with the PTC body 109. The motor 202 is started, driving the conveyor belt 201 to move and transport the substrates 300 to below the welding machine 205. During the transport process, the clamping plate 207 on the side wall of the mounting plate 206 contacts the side wall of the substrate 300 to prevent the substrate from shifting during transport. At the same time, the telescopic rod 30... 2. The fixed plate 303 and the limiting rod 304 are moved. The limiting rod 304 abuts against the front end of the substrate 300 to further fix the position of the substrate. The hydraulic rod 102 pushes the push block 108 to push the PTC body 109 in the storage box 105 through the discharge groove 110 so that it falls into the welding groove 301 on the top of the substrate 300. The welding machine 205 is started to accurately weld the PTC body 109 into the welding groove 301 of the substrate 300. After welding is completed, the conveyor belt 201 continues to run to transport the welded substrate 300 to the next process or collection area.
