In some embodiments, on the basis of the above embodiments, the pole piece splicing mechanism further includes a negative pressure generator, a negative pressure adsorption port 6 for adsorbing the cut pole piece waste is further formed in the upper surface of the splicing platform 1, the splicing platform 1 is further provided with a waste material box 7 for storing the pole piece waste adsorbed by the negative pressure adsorption port 6, one end of the waste material box 7 is connected with the negative pressure adsorption port 6 through a closed pipeline, and the other end of the waste material box 7 is connected with an air port of the negative pressure generator through a closed pipeline.

The negative pressure adsorption port 6 is connected with the negative pressure generator through a closed pipeline, when the negative pressure generator is started, the negative pressure adsorption port 6 is ventilated, air in the negative pressure generator is pumped away, and a vacuum state with negative pressure is formed. At this time, the air pressure inside the negative pressure generator is lower than the outside atmospheric pressure near the negative pressure adsorption port 6, and the pole piece waste is adsorbed under the action of the outside pressure. The higher the vacuum degree in the negative pressure generator is, the stronger the adsorption force of the negative pressure adsorption port 6 to the pole piece waste material nearby the negative pressure adsorption port is. The negative pressure generator is also called as a vacuum generator, and is a novel, efficient, clean, economic and small vacuum component which utilizes a positive pressure gas source to generate negative pressure. The most common cyclone negative pressure generator is to use a jet plate to jet compressed air at a high speed to form jet flow at an outlet of the jet plate to generate entrainment flow, and under the entrainment action, the air around an adsorption cavity is continuously pumped away, so that the pressure in the adsorption cavity is reduced to be lower than the atmospheric pressure to form vacuum. The negative pressure adsorption waste material has the advantages of cleanness, stable adsorption, reliability and no damage to the surface of an adsorbed object compared with a structure that a common fan blows away the waste material on the market, so that the negative pressure adsorption technology is widely applied to various fields.

In some embodiments, on the basis of the above embodiments, the control circuit further includes an ultrasonic sensor for detecting the pole winding allowance, and the ultrasonic sensor is disposed outside the pole winding and electrically connected to the main circuit.
Specifically, an ultrasonic sensor is added at the unwinding position of the pole roll, and the ultrasonic sensor can be arranged above, below or on the side surface of the pole roll.

When the infrared photoelectric sensor detects that no pole piece exists at the position above the infrared photoelectric sensor, that is, the old pole roll is used up, and a new pole roll needs to be added, a reminding program that no pole piece exists at the position above the reflection-type photoelectric switch sensor 9 can be executed. The infrared photoelectric sensor is a reflection type photoelectric switch sensor 9 which is widely used at present. It should be noted that, as will be understood by those skilled in the art, in practical applications, the reflective photoelectric switch sensor 9 may be in other forms, which are only exemplary, and the present embodiment does not limit the specific implementation of the reflective photoelectric switch sensor 9.
