Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Please refer to Figures 1-4 The utility model provides a kind of embodiment: the conveying line for big soft package battery liquid injection, including rack 1 and the crossbeam 101 fixed in rack 1 inside both ends, two layers of crossbeams 101 in vertical direction are respectively installed with upper chain roller conveying line 2 and lower chain roller conveying line 3, hollow shell 4 is installed on the outer wall of one side of rack 1, pulley transmission structure 5 for connecting upper chain roller conveying line 2, lower chain roller conveying line 3 is arranged in the inside of hollow shell 4, speed reducer motor 6 for driving upper chain roller conveying line 2 work is installed on the outer wall of one side of hollow shell 4, the rotary power of speed reducer motor 6 is transmitted to lower chain roller conveying line 3 by pulley transmission structure 5, so that upper chain roller conveying line 2, lower chain roller conveying line 3 synchronous conveying work piece, the top of one crossbeam 101 is provided with lifting material transfer assembly 7 for moving big soft package battery out of conveying line;

[0018] Big soft package battery work piece is horizontally transferred by upper chain roller conveying line 2, lower chain roller conveying line 3, to realize the continuous conveying of battery, guarantee the continuous performance of battery in liquid injection process;

[0019] The structure of upper chain roller conveying line 2, lower chain roller conveying line 3 is same, upper chain roller conveying line 2 includes straight linear section 201 fixed in the top of crossbeam 101 both sides, and a plurality of rollers 203 are rotatably installed in straight linear section 201 at equal intervals, chain wheel transmission structure 204 for power connection is installed between a plurality of rollers 203, transmission shaft 202 is installed between two rollers 203 in the same Y-axis direction, and the output end of speed reducer motor 6 is fixedly connected with one end of transmission shaft 202 through coupling;

[0020] The chain wheel transmission structure 204 is composed of synchronous chain wheels installed at the ends of the rollers 203 and chains wound between the synchronous chain wheels. The reduction motor 6 drives the transmission shaft 202 in the upper chain roller conveying line 2 to rotate. Since the transmission shaft 202 is power-connected with the rollers 203 through the chain wheel transmission structure 204, the rollers 203 rotate synchronously, so that the large jelly-roll battery workpiece is continuously transferred through the rollers 203. At this time, the upper chain roller conveying line 2 and the lower chain roller conveying line 3 can stably convey large and heavy batteries.

[0021] The lifting material transfer assembly 7 includes a U-shaped metal frame bottom 701 fixed between two linear profiles 201, and a Z-axis cylinder 702 installed at the top end of the U-shaped metal frame bottom 701.
