A case loading roller 236 is provided at the top of the case loading pressure rod 233; the case loading roller 236 is rotatably connected in the case loading cam groove 235, and the lifting and positioning of the case loading component is realized through the track of the case loading cam groove 235, so that the case loading pressure rod 233 can gradually lower along with the case loading cam groove 235 to automatically push the positive electrode plate placed on the case group into the case group. The case loading pressure head 234 is arranged at the lower end of the case loading pressure rod 233, and the positive electrode plate is ensured to completely enter the case group through the case loading pressure head 234, preventing the positive electrode plate from being placed on the edge of the case group. During normal case loading, when the case loading pressure head 234 is at the lowest position, it is non-contact with the positive electrode plate, about 1 mm away, to prevent the positive electrode plate from being crushed when the pressure head contacts the positive electrode plate at the low position.

[0027] An assembly transition turntable assembly 25 is further provided on the frame 1 between the case loading mechanism 23 and the liquid injection conveying mechanism 24. The structure of the assembly transition turntable assembly 25 is the same as that of the case group conveying turntable assembly. Through the case loading mechanism 23, the positive electrode plate placed on the case group can be automatically pushed into the case group without manual operation, and the assembly efficiency is greatly improved.

[0028] As Figure 5As shown, the liquid injection conveying mechanism 24 includes a liquid injection turret 241, a number of shell group positioning components arranged at intervals along the circumferential direction of the liquid injection turret 241, a liquid injection component, and an injection molding conveying turntable component 26; a liquid injection drive gear 2411 is connected to the bottom of the liquid injection turret 241; the liquid injection drive gear 2411 meshes with the total positive electrode sheet assembly transfer drive on the total positive electrode sheet assembly transfer drive mechanism through other gears, so as to achieve synchronous rotation and facilitate the smooth connection during conveying.

A shell group positioning space 240 is formed between the top surface of the shell group positioning seat 244 and the bottom surface of the shell group positioning pressing plate 2442.

[0030] As Figure 5As shown, the liquid injection assembly includes a liquid injection bracket 247, a plurality of liquid injection pumps 248 and a plurality of liquid injection joints 249; the liquid injection bracket 247 includes an upper liquid injection support plate 2471, a middle liquid injection connecting rod 2472 and a lower liquid injection support plate 2473; the upper liquid injection support plate 2471 and the lower liquid injection support plate 2473 are respectively fixedly mounted on the liquid injection turret 241, and an electro-liquid feeding part 2474 is arranged on the frame; the upper liquid injection support plate 2471 is provided with an electrical slip ring 2475; the electrical slip ring 2475 is divided into an upper and a lower part, and the upper and lower parts are rotatably connected, the upper part remains relatively still with the outside and receives electricity and air from the outside, and the lower part rotates together with the liquid injection turret 241 and supplies electricity and air to the turret, and the liquid injection pump 248 and other components that use electricity and air obtain power and air sources through the electrical slip ring 2475. The lower injection support plate 2473 is provided with a turret liquid storage barrel 2476; the steel pipe in the electro-hydraulic feed part 2474 axially passes through the electrical slip ring 2475 and passes into the interior of the turret liquid storage barrel 2476; the joint on the electro-hydraulic feed part 2474 is used to communicate with an external pump to send the electro-hydraulic into the electrical slip ring 2475, and then flow into the turret liquid storage barrel 2476 through the electrical slip ring 2475. A plurality of injection pumps 248 are arranged on the upper injection support plate 2471 at intervals along the circumferential direction, and each injection pump 248 is connected to each shell group support. The rod 243 is correspondingly arranged, and a plurality of injection joints 249 are arranged on the lower injection support plate 2473 at intervals along the circumferential direction.

The injection conveying turntable assembly 26 is transmission-connected to the total driving mechanism of the positive electrode assembly flow, and the injection conveying turntable assembly 26 is connected to the discharge end of the injection turret 241; the structure of the injection conveying turntable assembly is the same as that of the shell group conveying turntable assembly. Automated injection is achieved through the injection conveying mechanism 24, without the need for manual injection.

[0031] When the device is working, the shell groups enter the shell group feeding conveyor belt 212 one by one, and the shell groups on the shell group feeding conveyor belt 212 are pushed into the shell group feeding rotating disk 217 one by one along the shell group feeding guide plate 213. The shell group feeding rotating gear is driven to rotate by the total driving mechanism for the assembly and transfer of the positive electrode plates, so that the shell group feeding rotating disk 217 rotates, thereby transferring the shell groups into the placement space of the shell inserting mechanism 23. The positive electrode plates enter the positive electrode plate conveying line 222 one by one, and the positive electrode plates are conveyed to the shell group feeding rotating disk 217 of the positive electrode plate conveying rotating disk assembly one by one in the conveying mode of the conveyor belt through the positive electrode plate conveying line 222. The positive electrode plates are pushed into the shell inserting limit notch 2314 of the shell inserting mechanism 23 by the rotation of the positive electrode plate conveying rotating disk assembly and the subsequent pushing of the positive electrode plates, so that one positive electrode plate is placed on each shell group. By the rotation of the shell inserting turret 231, the shell inserting rollers 236 on the shell inserting pressure rod 233 roll along the shell inserting cam groove 235 and gradually descend along the track of the shell inserting cam groove 235, so that the shell inserting pressure head 234 gradually presses the misaligned positive electrode plates into the shell groups completely. The shell groups after pressing are transferred to the shell group positioning notch 2441 of the liquid injection conveying mechanism 24 through the assembly transition rotating disk assembly 25 with the rotation of the shell inserting turret 231. By the rotation of the liquid injection turret 241, the shell group support rod 243 rises along the track of the liquid injection cam groove 245, and the shell groups are pressed tightly between the shell group positioning pressure plate 2442 and the shell group support rod 243. When the upper liquid injection pump 248 is at the position where the shell groups are pressed tightly, the electro-hydraulic fluid is conveyed to the liquid injection joint 249, and is injected into the shell groups through the liquid injection joint 249 to complete the liquid injection. After the liquid injection, the liquid-injected shell groups are transferred to the injection molding conveying rotating disk assembly 26 with the rotation of the liquid injection turret 241 and flow onto the shell group feeding conveyor belt 212 for conveying. The above process realizes automatic operation, eliminates the need for manual assembly, saves time and effort, further ensures the pressing quality and is convenient for better control of the liquid injection volume, and changes from linear conveying to rotary conveying, further improving the conveying efficiency and finally improving the overall production efficiency.

[0032] In summary, the advantages of the present utility model are that the device realizes the automatic feeding of the positive electrode plates and the shell groups through the positive electrode plate feeding device, presses the positive electrode plates into the shell groups at the same time, and can also automatically inject liquid into the shell groups; replaces manual processing, realizes automatic operation, saves time and effort, greatly improves the production efficiency, and ensures the assembly consistency and assembly quality through automatic assembly.
