Description

TECHNICAL FIELD

[0001] The present application relates to the field of lithium ion battery pack production, in particular to a cutting and placing device for parallel connection. BACKGROUND

[0002] As the main energy form of electric vehicles, lithium ion battery packs have always been the focus of many production and research units, and their performance directly affects the overall performance of electric vehicles. In terms of structure, lithium ion battery packs are composed of multiple modules in series, and each module is composed of multiple modules in series, and each module is composed of multiple arrayed cells in parallel. Therefore, in terms of production process, first, the cells are sorted, and each cell is sorted according to voltage and resistance; after cell sorting, the cells need to be rested; then, the cell is inserted into the shell, the cell is inserted into the double-sided clamp to form a battery module; then, each module is stacked to form a battery module, and the two ends of the battery module are provided with positive and negative busbars; finally, each battery module is connected in series through the busbars to form the required lithium ion battery pack.

[0003] In the lithium ion module forming process, a parallel connection is needed, which is placed at both ends of the lithium ion module to realize the parallel connection of each cell in the module. The parallel connection includes multiple longitudinally spaced longitudinal nickel strips and multiple transversely spaced transverse nickel strips, and the intersection of the longitudinal nickel strips and the transverse nickel strips is welded together by a spot welding machine. In the existing parallel connection production process, manual positioning with a nickel strip positioning disc is generally used. The top surface of the nickel strip positioning disc is longitudinally spaced apart to provide longitudinal grooves for placing longitudinal nickel strips, and the top surface of the nickel strip positioning disc is transversely spaced apart to provide transverse grooves for placing transverse nickel strips. The worker needs to pull out the nickel strip from the payoff reel, cut it, and place it in the longitudinal groove and transverse groove on the nickel strip positioning disc, respectively, and then use a spot welding machine to weld the longitudinal nickel strip and the transverse nickel strip together to obtain the parallel connection. However, the existing parallel connection production is carried out manually, which has low production efficiency and high labor intensity. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a cutting and placing device for parallel connection, which realizes automatic placing and cutting of parallel connection, improves production efficiency, and reduces labor intensity.

[0005] The technical scheme adopted by the present application to solve the above technical problems is: a cutting and placing device for parallel connection, characterized in that: the device comprises a conveying belt, a first laying mechanism arranged on the conveying belt to longitudinally lay a nickel strip on a nickel strip positioning disc, and a second laying mechanism arranged on the conveying belt to transversely lay the nickel strip on the nickel strip positioning disc; the conveying belt is provided with a conveying table for placing the nickel strip positioning disc; the first laying mechanism and the second laying mechanism each comprise a feeding and cutting assembly and a placing assembly; the feeding and cutting assembly and the placing assembly of the first laying mechanism are oppositely arranged along the conveying direction of the conveying belt; the feeding and cutting assembly and the placing assembly of the second laying mechanism are oppositely arranged along the vertical direction of the conveying direction of the conveying belt; the feeding and cutting assembly comprises an upright frame and a plurality of payoff reels arranged at intervals; a group of feeding rollers for conveying the nickel strip are arranged on the upright frame opposite to the payoff reels; a cutting cylinder is arranged on the upright frame opposite to the conveying belt; the output end of the cutting cylinder is provided with a cutting knife; the placing assembly comprises an upright rod arranged above the conveying belt, a connecting block movably arranged on the upright rod, and a supporting plate connected to the lower portion of the connecting block; a clamping cylinder is arranged on the supporting plate; the output end of the clamping cylinder is provided with a clamping plate; the outer end of the clamping plate and the supporting plate forms a clamping opening for clamping the nickel strip.

[0006] As an improvement, the upright frame comprises a bottom plate, a group of outer side plates vertically and oppositely arranged on the bottom plate, an outer top plate arranged on the top of the outer side plates, a guide strip arranged on the inner wall of the outer side plate, an inner side plate slidably arranged in the inner portion of the outer side plate, and an inner top plate arranged on the top of the inner side plate; one of the feeding rollers is arranged on the bottom portion of the outer side plate, and the other feeding roller is arranged on the bottom portion of the inner side plate. By adjusting the height of the inner side plate on the outer side plate, the spacing between the group of feeding rollers is adjusted. Since the nickel strip on the payoff reel passes through the gap between the group of feeding rollers, the tension state of the nickel strip is easily controlled.

[0007] As a further improvement, the payoff reel is arranged on a payoff shaft, and a separation sleeve is arranged between adjacent two payoff reels on the payoff shaft. The separation sleeve avoids interference between adjacent two payoff reels, and ensures the distance between adjacent nickel strips.

[0008] As a further improvement, the conveying belt comprises two sub-conveying belts arranged side by side to form a gap in the middle, and the two sub-conveying belts share the same conveying shaft. The gap between the two sub-conveying belts is used to arrange the conveying table and install a position sensor.

[0009] Compared with the prior art, the advantages of this invention are as follows: The conveyor belt transports the nickel strip positioning plate to the first laying mechanism. The placement component on the first laying mechanism moves closer to the feeding and cutting component of the first laying mechanism. The clamping cylinder of the first laying mechanism actuates, and the clamps on the first laying mechanism clamp each nickel strip. The placement component of the first laying mechanism retracts and resets, and each nickel strip of the first laying mechanism is placed in the longitudinal groove on the nickel strip positioning plate. The cutting cylinder of the first laying mechanism actuates, and the cutting blade cuts each nickel strip, thus realizing the parallel longitudinal laying of nickel strips on the nickel strip positioning plate. Afterward, the conveyor belt transports the conveyor table... The strips are fed to the second laying mechanism, where the placement components move closer to the feeding and cutting components. The clamping cylinder of the second laying mechanism actuates, and the clamps on the second laying mechanism hold each nickel strip. The placement components of the second laying mechanism retract and reset, and each nickel strip is placed in the horizontal groove on the nickel strip positioning plate. The cutting cylinder of the second laying mechanism actuates, and the cutting blade cuts each nickel strip. This realizes the parallel laying of horizontal nickel strips on the nickel strip positioning plate, ultimately achieving automatic placement and cutting in a parallel network, improving production efficiency, and reducing the labor intensity of workers.
