By moving the second rotary cylinders 43 through the material transfer module 42, the adsorbed soft-pack batteries are continuously transported from the soft-pack carrier 45 to the soft-pack positioning component and unloaded onto the end soft-pack carrier 45.

[0031] After the pouch battery is transported onto the first pouch battery positioning component 1, it needs to be glued. Gluing and cutting are achieved through the combined action of the pulling cutting component 6 and the bidirectional glue-taking device 15. Specifically:

[0032] First, a tape 39 placement assembly 7 is provided at the end. The tape 39 placement assembly 7 is used to place the tape 39 and includes a tray 38 on which the tape 39 is wound. A guide wheel 40 is provided at the pull-out end of the tape 39 to guide the extension direction of the tape 39 end.

[0033] A pull-cutting component 6 is provided at the first soft-pack battery positioning component 1, and a bidirectional glue-taking device 15 is located between the first soft-pack battery positioning component 1 and the pull-cutting device.

[0034] like Figure 3 , Figure 4The pulling cutting assembly 6 is located in the direction of the tape 39, and the tape 39 is discharged by the tape 39 discharging assembly 7, which includes a reel 38 on which the tape 39 is wound, and a guide wheel 40 is arranged at the end of the tape 39, and the guide wheel 40 is arranged in three groups alternately, and one end of the tape 39 is pulled by the pulling cutting assembly 6, and the pulling cutting assembly 6 includes a conveying module 8, and the sliding block of the conveying module 8 is connected with a fixed plate 9, and the fixed plate 9 is connected with a sliding plate 10 which is connected with a push-pull air cylinder 11 at the end; the push-pull air cylinder 11 can drive the sliding plate 10 to slide on the fixed plate 9, and the sliding plate 10 is close to or away from the double-way tape taking device 15, and is used for adapting the distance between the two; at least two groups of positioning plates 12 are arranged at the end of the fixed plate 9, and two groups of pressing air cylinders 13 are arranged on the fixed plate 9, and the output end of the pressing air cylinder 13 is connected with an elongated block 14 which is pressed on the positioning plate 12; the side of the fixed plate 9 away from the tape 39 is provided with a cutting knife 46, and the cutting knife 46 is connected with a cutting air cylinder 47 which drives the cutting knife 46 to cut.

[0035] As shown in Figure 5 The double-way tape taking device 15 includes a stand 16, and a connecting shaft 17 is arranged between the stand 16, and a first rotating air cylinder 48 is arranged at one end of the connecting shaft 17, and two groups of extension plates 18 are arranged on the connecting shaft 17, and a suction air cylinder 19 is arranged on each of the extension plates 18, and an elongated suction head 20 is connected to the output end of the suction air cylinder 19, and the two groups of elongated suction heads 20 are respectively directed to the suction bottom block 2 and the positioning plate 12, and the connecting shaft 17 is rotated by the first rotating air cylinder 48, and then drives the two groups of elongated suction heads 20 to move alternately between the pulling cutting assembly 6 and the soft package positioning assembly, that is, the tape 39 obtained by the pulling cutting assembly 6 is rotated to one side of the soft package battery on the soft package positioning assembly.

[0036] The working mode of the pulling cutting assembly 6 and the double-way tape taking device 15 is as follows:

[0037] When the conveying module 8 drives the pressing cylinder 13 to approach the adhesive tape 39, the pressing cylinder 13 on the side away from the adhesive tape 39 is extended, so that the elongated block 21 presses the adhesive tape 39 and is pressed on the positioning plate 12, the adhesive surface of the adhesive tape 39 faces the side of the pressing block, then the adhesive tape 39 is pulled out by the conveying module 8 until the position of the elongated suction head 20, the surface of the elongated suction head 20 is densely covered with suction holes 41, which can adsorb the non-adhesive surface of the adhesive tape 39, then the elongated block 21 is arranged on the side of the cutting knife 46, the elongated block 21 is connected with the positioning cylinder 22, the positioning cylinder 22 is extended to drive the elongated block 21 to press the end of the adhesive tape 39 on the elongated suction head 20, at this time, the adhesive tape 39 is positioned on the elongated suction head 20, the conveying module 8 continues to move to the direction of the adhesive tape 39 roll, after the adhesive tape 39 is pressed by the pressing cylinder 13 again, the cutting knife 46 on the side of the elongated suction head 20 cuts the adhesive tape 39, at this time, the vacuum suction head 3 has the cut adhesive tape 39 adsorbed, the elongated suction head 20 with the adhesive tape 39 is rotated upward by the first rotary cylinder 48, that is, the adhesive tape 39 is separated from the positioning block, the vacuum suction head 3 with the adhesive tape 39 is turned to the soft package positioning assembly to paste the adhesive on the soft package battery. The other end of the elongated suction head 20 moves to the pulling and cutting position, the conveying module 8 continues the previous action, and reciprocates in turn, so that the adhesive can be taken during pasting, and the work efficiency is improved.

[0038] In addition, in the embodiment, since the adhesive tape has a certain strength, in order to ensure that the adhesive tape 39 does not deviate during cutting and positioning on the elongated suction head 20, and to ensure that the cutting is not skewed, a tape blocking mechanism 23 is further arranged, as shown in Figure 3 、 Figure 4 The tape blocking mechanism 23 includes an L-shaped block 24 elastically connected to the sliding plate 10, the L-shaped block 24 is provided with a blocking block 25, the blocking block 25 is located above the positioning plate 12, the L-shaped block 24 is connected to the sliding plate 10 through a sliding rail, the sliding plate 10 is provided with a limiting block 26, and an elastic element 27 is arranged between the L-shaped block 24 and the limiting block 26. When the sliding plate is pushed close to the elongated suction head 20, the blocking block 25 arranged at the end of the L-shaped block 24 is pressed on the vacuum suction head 3 and above the positioning plate 12, the positioning plate 12 is provided with a square slot 28, the adhesive tape 39 is located at the opening of the square slot 28, the blocking block 25 includes two openings 29 arranged at the two ends, and the openings 29 are pressed at the square slot 28. At this time, the pressing plate and the positioning plate 12 can completely limit the adhesive tape 39 on the elongated suction head 20, so as to prevent the adhesive tape 39 from deviating due to the fact that part of the adhesive tape 39 is not completely adsorbed on the limiting block 26. After the cutting is completed, the sliding plate 10 retreats, the blocking plate is separated from the positioning plate 12, and the elongated suction head 20 is convenient to rotate.

[0039] For the attaching process, further described, through the long adsorption head 20 adsorbed by the adhesive tape 39 to the soft package battery positioning assembly 1, then through the adsorption cylinder extension will be attached to the soft package battery side, and then through the upper material removal mechanism to the next soft package battery positioning assembly 1, its side is provided with a glue rolling mechanism 30, as shown in Figure 6 The glue rolling mechanism 30 includes a mounting frame 31, the mounting frame 31 is provided with a push cylinder 32, the output end of the push cylinder 32 is connected with a bracket 33, the bracket 33 is rotatably connected with two groups of upper and lower rubber rollers 34, the rubber rollers 34 are provided with connecting rods 35 at both ends, the connecting rods 35 are connected with the bracket 33 through rotating shafts, the connecting rods 35 are provided with connecting plates 36 at the ends, the upper and lower connecting plates 36 are respectively connected with the bracket 33 through springs 37, the rubber rollers 34 are pushed close to the soft package battery by the push cylinder 32, and the soft package battery enters between the two groups of rubber rollers 34. The connecting rods 35 of the rubber rollers 34 are provided with springs 37 on the other side, when the two groups of rubber rollers 34 are stretched, the springs 37 are compressed, which can ensure that the rubber rollers 34 are mutually opened to attach the adhesive tape 39 on the edge of the soft package battery.

[0040] And the two sides of the soft package battery, the adsorption bottom block 2 of the soft package battery positioning assembly 1 can be provided with multiple groups of adsorption heads 3, when one side of the soft package battery is attached, then move one station through the material removal mechanism, and at the same time, the rotating cylinder is rotated by 180°, so that the other side of the soft package battery faces the position of the adhesive tape, and finally is carried to the glue rolling mechanism 30, which is also provided with two stations, and the rotating cylinder is rotated respectively to roll the glue and attach it. The device greatly improves the work efficiency, and if four groups of the machine are set, 2000 groups of adhesive tape can be attached per hour.
