The support base 135 is supported between the two mounting assemblies. The position of the automatic endless belt device 1 can be adjusted by pushing the first carriage 162 by the adjusting cylinder 163 to slide up and down on the first slide rail 161. Each mounting assembly further includes a stop block 711, and the stop block 711 is used for limiting the moving stroke of the first sliding frame 162.
The controller of the automatic tape changer 1 is provided in the operation interface 960. The controller is electrically connected with cylinders such as a pole piece material belt driving mechanism 2, a spare pole piece material belt driving mechanism 3, a belt splicing device 1, a pole piece deviation correcting device 3, a pole piece deviation correcting device 4, a waste collecting shaft and the like so as to drive all mechanisms to cooperatively work to automatically complete feeding and belt changing.
The tape splicing process is described as follows:
take the pole piece material wheel 820 in operation and the spare pole piece material wheel 821 as an example. When the material roll on the pole piece material wheel 820 is running out, the pressure sensor 930 gives an alarm to the controller, and the belt pressing mechanism presses the currently used pole piece to prevent the currently used pole piece from moving. At this time, the spare pole piece on the spare pole piece wheel 821 is manually inserted between the first tape splicing suction cup 729 and the second tape splicing suction cup 769 of the automatic tape splicing device 1 and then connected with the waste collection shaft 941. Starting the automatic tape splicing device 1, the first tape splicing sucker 729 and the second tape splicing sucker 769 are attached to the two pole piece material belts of the used pole piece material belt and the standby pole piece material belt in equal height.
Under the action of the cutter cylinder 734, the pole piece cutter 732 stretches out from the middle of the first tape splicing suction cup 729 or the second tape splicing suction cup 769 to cut off two pole piece material tapes, and then the waste collection shaft 941 and the unreeling shaft 822 rotate under the driving of the unreeling motor 901 and the waste collection wheel motor to drive two surplus pole piece material tapes to separate from the two tape splicing suction cups, namely the first tape splicing suction cup 729 and the second tape splicing suction cup 769. After the excess materials are removed, the pole piece materials sucked by the first tape splicing sucker 729 and the second tape splicing sucker 769 are the residual parts of the used pole piece material belts and the initial parts of the standby pole piece material belts. Then the controller drives the left side glue preparation mechanism to prepare glue, and the first glue pasting mechanism pastes glue to the cutting interface of the used pole piece material belt and the spare pole piece material belt from the left side; and then the controller drives the right side glue preparation mechanism to prepare glue, and the second glue pasting mechanism pastes glue to the cut-off interface of the used pole piece material belt and the spare pole piece material belt from the right side.
The first adhesive tape and the second adhesive tape on the left and right adhesive preparation mechanisms are prepared by feeding mechanisms, such as an adhesive preparation wheel, an adhesive passing roller 213, an adhesive passing smooth wheel 214 and an adhesive passing smooth wheel 215 of the first feeding mechanism. Through the clamping mechanism, for example, through the clamping fixed block 116 and the clamping rotating block 117 in the second clamping mechanism. The tape is clamped by the clamping mechanism, for example, the clamping rotating block 117 and the clamping fixing block 116 are closed to clamp the tape under the action of the first clamping cylinder 239 of the first clamping mechanism, the first pasting moving plate 409 is moved forward under the pushing of the first drawing cylinder 237, and then the pasting suction cup 430 is moved forward to approach and adsorb the tape. Then, the first glue pressing cylinder 349 is started to drive the first glue pressing block 346 to rotate to press the adhesive tape extending from the glue clamping mechanism on the first gluing suction cup 430, after the adhesive tape is pressed by the first gluing suction cup 430 and the first glue pressing block 346, the glue clamping mechanism releases the clamped adhesive tape, then the first gluing moving plate 409 returns to the original position, and the glue clamping mechanism clamps the adhesive tape again. The adhesive tape clamped at both ends is cut by the adhesive cutting mechanism, for example, by the adhesive cutting knife 106 of the first adhesive cutting mechanism. The cut off adhesive tape section is sucked by the adhesive tape sucking disc, for example, the first adhesive tape sucking disc 430 sucking the adhesive tape moves upwards to be attached to the second adhesive tape connecting sucking disc 769, and therefore one side of the cut-off interface of the two pole piece material tapes is connected with the adhesive tape section in a sticking mode. In a similar way, the second rubberizing sucker moves upwards to be attached to the first tape splicing sucker 729, the other side of the second rubberizing sucker is attached to the cut-off connector of the two-pole sheet material tape, and two sides are attached and connected. And finally, the residual spare pole piece material belt using the pole piece material belt to draw the new connected belt continues to work, so that automatic belt changing and roll changing are realized. And vice versa.
The automatic tape changing device for winding the battery cell of the embodiment cuts the adhesive tape with required length through the adhesive tape preparing mechanism, the double-sided adhesive tape is completed at the cut-off interface of the pole piece material tape and the spare pole piece material tape through the first adhesive tape pasting mechanism and the second adhesive tape pasting mechanism in a full-automatic mode, the full-automatic tape changing device with better tape splicing effect is provided, automatic tape changing is achieved, when the pole piece material tape is used and runs out, the spare pole piece material tape is connected with the pole piece material tape on the automatic tape changing device, and continuous work is not required to be stopped. Meanwhile, the automatic belt replacing device for winding the battery cell is provided with the waste collecting shaft, so that redundant excess materials can be removed in time. The automatic tape changing device for winding the battery cell of the embodiment is also provided with a pole piece deviation correcting device, so that pole pieces can be accurately aligned in the process of splicing the pole pieces, and the yield of the battery cell wound by equipment is improved.
