[0042] Please continue to refer to Figure 1As shown in the figure, the tape pressing mechanism 7 includes a driving roller 71, a tape pressing cylinder 72 and a tape pressing block 73. The tape pressing cylinder 72 drives the tape pressing block 73 to move relative to the driving roller 71, so as to press the pole piece tightly between the tape pressing block 73 and the driving roller 71, thereby pressing and fixing the pole piece.

[0043] As Figure 6 shown in the figure, when the coil diameter detector 12 detects that the pole piece coil located on the unwinding roller 11 has been completely unwound, the tape guiding rotation motor 342 drives the tape guiding driving wheel 343 to rotate, thereby driving the tape guiding driven wheel 344 to rotate, so as to drive the tape guiding suction cup rod 346 to rotate, aligning the tape guiding suction cup 347 with the end of the pole piece of the second unwinding mechanism 2. The tape guiding lateral driving module 34 drives the tape guiding moving seat 32 to move, so that the tape guiding suction cup 347 adsorbs the end of the pole piece.

The tool holder lateral movement cylinder 624 drives the tool holder moving plate 627 to extend relative to the tool holder support 623. The cutter lateral movement cylinder 6141 drives the cutter moving plate 6144 to move relative to the cutter support 613, so that the pressing plate 6126 abuts against the tool holder 628, compressing the elastic structure 6147, and making the cutter 6145 extend into the cutter groove 629, thereby cutting the pole piece.

[0044] As Figure 7 shown in the figure, after the pole piece is cut, the tape pressing cylinder 72 drives the tape pressing block 73 to move relative to the driving roller 71, so as to press the pole piece tightly between the tape pressing block 73 and the driving roller 71. The cutter lateral movement cylinder 6141 drives the cutter moving plate 6144 to reset relative to the cutter support 613. The cutter longitudinal movement cylinder 612 drives the cutter support 613 to rise along the cutter longitudinal movement guide rail 612. The floating cylinder 41 drives the floating mounting seat 43 to move along the floating guide rail 42, so that the two floating rollers 44 move relatively away from each other. The unwinding roller 11 drives to wind up the remaining coil.

[0045] As Figure 8 shown in the figure, the longitudinal driving module 33 drives the tape guiding suction cup assembly 34 to move, so that the tape guiding suction cup rod 346 drives the end of the pole piece strip in the second unwinding mechanism 2 to move onto the tool holder 628, and the tool holder 628 adsorbs and fixes the end of the strip.

[0046] As Figure 9 shown in the figure, driven by the first tape sticking assembly 63, the adhesive tape is attached to the cut end of the old strip and the end of the new strip, thereby realizing strip connection.

[0047] As Figure 10As shown, the tool holder 628 stops adsorbing the pole piece, the longitudinal moving cylinder 621 of the tool holder drives the tool holder bracket 623 to move upward along the longitudinal moving guide rail 622 of the tool holder, and is driven by the second tape sticking assembly 64 to stick the adhesive tape to the cut end of the old tape and the end of the new tape, so as to realize sticking the adhesive tape to both end faces of the pole piece. Subsequently, the longitudinal driving module 33 drives the tape sucking assembly 34 to descend and reset, and the floating cylinder 41 drives the floating mounting seat 43 to move along the floating guide rail 42, so that the two floating rollers 44 approach relatively, and the two floating rollers 44 act relatively to press the pole piece tightly.

[0048] As Figure 11 shown, the tape pressing cylinder 72 drives the tape pressing block 73 to move away from the driving roller 71 relatively, so as to loosen the pole piece.
