Description

Technical Field

[0001] The present invention relates to the field of lithium-ion battery pack production, and particularly to a parallel network automatic cutting and placing machine. Background Art

[0002] As the main energy form of electric vehicles, lithium-ion battery packs have always been a hot spot for many production and R & D units to invest in, and their performance directly affects the overall performance of electric vehicles. Structurally, a lithium-ion battery pack is formed by connecting multiple modules in series, and each module is formed by connecting multiple blocks in series, and each block is formed by connecting multiple cells arranged in an array in parallel. In terms of the production process, first, cell sorting is carried out to grade each cell according to voltage and resistance; after cell sorting, the cells need to be statically placed; then, the cells are put into the shell, and the cells are inserted into the double-sided fixture to form a battery block; then, each block forms a battery module through stacking and pressing, and a positive bus bar and a negative bus bar are respectively arranged at both ends of the battery module. Finally, each battery module is connected in series with each other through the bus bar to form the required lithium-ion battery pack.

[0003] In the lithium-ion module forming process, a parallel network is required. The parallel network is placed at both ends of the lithium-ion module to realize the parallel connection of each cell in the module. The parallel network includes multiple longitudinally spaced longitudinal nickel strips and multiple transversely spaced transverse nickel strips, and the intersections of the longitudinal nickel strips and the transverse nickel strips are welded together by a spot welder. In the existing production process of the parallel network, generally, manual operation is carried out using a nickel strip positioning plate. Longitudinal grooves for placing longitudinal nickel strips are longitudinally spaced on the top surface of the nickel strip positioning plate, and transverse grooves for placing transverse nickel strips are transversely spaced on the top surface of the nickel strip positioning plate. Workers need to draw out the nickel strips from the unwind reel, cut them, and respectively place them above the longitudinal grooves and the transverse grooves on the nickel strip positioning plate. Then, the longitudinal nickel strips and the transverse nickel strips are welded together by a spot welder to finally obtain the parallel network. However, the existing production of the parallel network is carried out manually, resulting in low production efficiency and high labor intensity for workers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a parallel network automatic cutting and placing machine aiming at the current situation of the prior art, which realizes the automatic placement and cutting of the parallel network, improves the production efficiency, and at the same time reduces the labor intensity of workers.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: A parallel-connected automatic cutting and placing machine, characterized in that it includes a first conveyor belt, a second conveyor belt arranged in parallel with the first conveyor belt, a first conveying platform arranged on the first conveyor belt for placing a nickel strip positioning disk, a second conveying platform arranged on the second conveyor belt for placing a nickel strip positioning disk, a pushing component arranged at one end of the first conveyor belt for pushing the nickel strip positioning disk on the first conveying platform onto the second conveying platform, a first laying mechanism arranged at one end of the second conveyor belt for longitudinally laying the nickel strip onto the nickel strip positioning disk, and a second laying mechanism arranged in the middle of the second conveyor belt for transversely laying the nickel strip onto the nickel strip positioning disk.

The placing component includes a vertical rod arranged above the second conveyor belt, a connecting block movably arranged on the vertical rod, a support plate is connected below the connecting block, a clamping cylinder is arranged on the support plate, and the output end of the clamping cylinder is provided with a clamping plate. The outer ends of the clamping plate and the support plate form a clamping opening for clamping the nickel strip.

[0006] As an improvement, the first conveyor belt and the second conveyor belt each include two sub-conveyor belts arranged in parallel with a gap formed in the middle. The two sub-conveyor belts share the same conveying shaft, and a gap is formed between the two sub-conveyor belts. On the one hand, it is convenient for the arrangement of the conveying platform. On the other hand, the gap can be used to install a position sensor.

[0007] Further improvement, the other end of the first conveyor belt is provided with a loading belt for conveying the nickel strip positioning disk. An end of the loading belt is provided with a loading component for placing the nickel strip positioning disk on the loading belt onto the first conveying platform. The loading component includes a loading moving frame moving along the direction of the first conveyor belt above the loading belt, a loading rotating cylinder arranged below the loading moving frame, and a loading clamping member arranged below the loading rotating cylinder. The empty nickel strip positioning disk is conveyed to the loading component through the loading belt. The loading clamping member clamps the nickel strip positioning disk. The loading rotating cylinder drives the nickel strip positioning disk to rotate 90 degrees, so that the length direction of the nickel strip positioning disk is synchronized with the first conveyor belt. The loading moving frame moves the nickel strip positioning disk onto the first conveyor belt, and the loading clamping member releases the nickel strip positioning disk, realizing the automatic loading of the nickel strip positioning disk onto the first conveyor belt.

[0008] Further improvement: at the other end of the second conveyor belt, there is a discharge belt for conveying the parallel network together with the nickel strip positioning disc to the spot welder.

By adjusting the height of the inner side plate on the outer side plate, the adjustment of the distance between a set of unwinding rollers is realized. Since the nickel strip on the unwind reel passes through the gap between a set of unwinding rollers, it is convenient to control the tension state of the nickel strip.

[0012] Further improvement: the unwind reel is arranged on a winding shaft. A spacer sleeve is arranged between adjacent unwind reels on the winding shaft. By arranging the spacer sleeve, interference between adjacent unwind reels is avoided.

The first conveying table and the second conveying table are arranged adjacent to each other. The pushing component pushes the nickel strip positioning disk on the first conveying table onto the second conveying table. Then, the placing component on the first laying mechanism approaches the feeding and cutting component of the first laying mechanism. The clamping cylinder of the first laying mechanism acts. The clamping jaws on the first laying mechanism clamp each nickel strip. The placing component of the first laying mechanism retreats and resets. Each nickel strip on the first laying mechanism is placed in the longitudinal groove on the nickel strip positioning disk. The cutting cylinder of the first laying mechanism acts.
