In addition, in order to prevent the scattered of defective pole pieces, a pressure spring and a pressure wheel are arranged in the winding needle positioning cylinder and used as a pressing mechanism to press the pole pieces, so that the pole pieces are prevented from scattering, the setting of the pressing mechanism limits the winding length of the winding needle for the defective pole pieces, meanwhile, the pressing mechanism is poor in action reliability, the pressure spring is easy to lose efficacy, and the pressing mechanism cannot maintain the pressing of the defective pole pieces. In addition, in order to ensure that the winding needle positioning cylinder can freely extend out and extend into a panel of the core winding machine, and avoid the winding needle positioning cylinder from occupying too much space and collision with other devices, the diameter of the winding needle positioning cylinder is not too large, but the winding length of the winding needle to a defective pole piece is further limited. Moreover, due to the inherent structural design of the winding needle positioning cylinder, a pole piece guide rod is required to be arranged on the winding needle positioning cylinder to guide the pole piece to the winding needle, and the arrangement of the pole piece guide rod can additionally increase the difficulty of pole piece entering.

The following describes the operation of the single-roll pole piece adhesive tape sticking device 100:
when the preceding stage device of the pole piece single roll rubberizing device 100 detects that the unreeled pole piece has a defective section, a corresponding detection signal is sent to a control system of the electric core winder, so that the control system marks the defective section of the pole piece.
When the defective pole piece is transferred to the pole piece single roll rubberizing device 100, the pole piece inserting and cutting device of the electric core winding machine inserts the defective pole piece to a specified position (as shown in fig. 3) and enables the defective pole piece to keep a straightened state. Then, the control system sends the control system to the single pole piece roll rubberizing device 100, so that the first driving mechanism 23 drives a corresponding one of the winding needles 22 to rotate, and the pole piece channel 222 of the winding needle 22 is aligned with the defective pole piece.
Then, the driving unit 3 drives the first sliding seat 21 to slide along the first guide rail 11 and move toward the panel, so that the winding needle 22 extends out of the panel and the defective pole piece is inserted into the pole piece passage 222 of the winding needle 22. When the driving unit 3 drives the first sliding seat 21 to move to the proper position, the second driving mechanism 25 drives the rotating shaft 241 to rotate, so that the pressing wheel 242 presses the defective pole piece onto the needle body 221 of the winding needle 22. Subsequently, the first driving mechanism 23 drives the corresponding one of the winding pins 22 to rotate again, so that the winding pin 22 winds the defective pole piece.
After the winding unit 2 finishes the fixed-length winding of the defective pole piece section of the pole piece, the pole piece is inserted into the cutting device to cut off the pole piece, so that the defective pole piece is cut off from the pole piece material roll. The first driving mechanism 23 continues the winding needle 22 to terminate the cut defective pole piece. After finishing the ending of the defective pole pieces, the first driving mechanism 23 suspends the driving of the winding needle 22, and simultaneously, the driving unit 3 drives the first sliding seat 21 to retract for the first time, so that the winding needle 22 retracts into the panel, and the defective battery cell wound by the winding needle 22 moves to the gluing unit 4.
Next, the third driving mechanism 43 of one gluing unit 4 corresponding to the winding needle 22 drives the second sliding seat 421 to move towards the winding needle 22, so that the adhesive tape on the glue preparation roller is glued to the defective battery cell, and then the first driving mechanism 23 drives the winding needle 22 to rotate again, so as to wind the adhesive tape on the defective battery cell. After the winding of the fixed-length adhesive tape is completed, the first driving mechanism 23 stops driving the winding needle 22, the second driving assembly 424 drives the connecting frame 423 to rotate in the second direction, so that the cutter 4232 on the connecting frame 423 drives the connecting frame 423 to rotate in the first direction, and then the pressure plate 4231 presses the new free end of the adhesive tape on the standby adhesive roller.
Then, the third driving mechanism 43 drives the second sliding seat 421 to reset, and at the same time, the second driving mechanism 25 drives the rotating shaft 241 to rotate in the opposite direction, so that the pressing wheel 242 releases the pressing of the defective battery cell. Subsequently, the fourth driving mechanism 52 of the striker unit 5 drives the shutter 51 to move toward the winding needle 22, so that the winding needle 22 is located in the escape groove 511 of the shutter 51.
Then, the driving unit 3 drives the first sliding seat 21 to perform a second retraction until the first sliding seat 21 returns to the initial position. During the retraction process of the first sliding seat 21, the defective battery cell on the winding needle 22 gradually moves towards the baffle 51 until one end of the defective battery cell contacts the baffle 51, and when the defective battery cell contacts the baffle 51, the baffle 51 blocks the defective battery cell from continuing to move along with the winding needle 22, so that the defective battery cell is stripped from the winding needle 22.
When the defective electric core is peeled from the winding needle 22 and falls onto the receiving plate 61 of the recovery unit 6, the pushing mechanism 63 of the recovery unit 6 pushes the defective electric core remaining on the gentle portion 611 of the receiving plate 61 to the inclined portion 612, so that the defective electric core passes through the inclined portion 612 and falls into the recovery box 62, and then the pushing mechanism 63 resets. And after the defective battery cell is peeled off from the winding pin 22 and falls, the fourth driving mechanism 52 of the material blocking unit 5 drives the blocking plate 51 to return to the initial position.
In the winding process of the defective pole piece, the second driving mechanism 25 can drive the rotating shaft 241 to rotate slightly to finely adjust the position of the pressing wheel 242, so that the position of the pressing wheel 242 can be changed according to the diameter of the wound defective pole piece, and the winding needle 22 can be ensured to wind the defective pole piece smoothly.
