[0033] The motion process is as follows: the wireless charging coil and the vibration motor are fixed to the end of the mechanical arm through corresponding suction cups or clamps, then the wireless charging coil and the vibration motor are moved to the upper side of the automatic rotating film tearing mechanism under the driving of the mechanical arm, the first clamping block is driven by the first clamping cylinder to clamp the first film attached to the wireless charging coil, at the same time, the elastic roller 7 is driven by the first cylinder to move upward and press the wire of the wireless charging coil, so that the wire of the wireless charging coil is tightly attached to the end of the mechanical arm, in some optional embodiments, a buffer pad for abutting can be arranged at the corresponding wire of the wireless charging coil on the end of the mechanical arm, so as to avoid the entanglement of the first film and the wire in the subsequent film tearing process, then the rotating mechanism 4 drives the first clamping mechanism 5 to rotate by 120 degrees, so that the first film is partially separated from the wireless charging coil in a winding manner, then the first clamping mechanism 5 is lowered under the driving of the first linear movement mechanism 3 to completely tear off the first film from the wireless charging coil, then the first clamping mechanism 5 releases the first film, since the rotation angle of the first clamping block is only 120 degrees, the first film will not be entangled on the first clamping block, and the air nozzle can blow the first film away from the automatic rotating film tearing mechanism, then the first cylinder drives the elastic roller 7 to reset, the reason for partially separating the first film from the wireless charging coil before tearing off the first film is that directly tearing off the first film may cause the first film to be pulled off, the first film is wound on the first clamping block to separate the joint between the first film and the wireless charging coil into an opening, then in the subsequent film tearing process, the first film can be separated from the wireless charging coil along the opening, and opening an opening as a breakthrough before tearing off the first film reduces the possibility of the first film being pulled off, after the first film is torn off, the first linear movement mechanism 3 moves upward and resets, then the second clamping mechanism 10 approaches the vibration motor under the driving of the third linear movement mechanism 8, in this embodiment, the vibration motor is connected with the product through a contact, so it does not need to consider the problem of the wire, the second clamping mechanism 10 clamps the second film, then the mechanical arm drives the vibration motor to slowly move upward, and the second film is partially separated from the vibration motor, then the second clamping mechanism 10 moves downward under the driving of the first linear movement mechanism 3, at the same time, the vibration motor moves upward under the driving of the mechanical arm, and the two cooperate to separate the vibration motor and the second film, the reason for partially separating the second film from the vibration motor before tearing off the second film is that directly tearing off the second film may cause the second film to be pulled off, since the vibration motor has a small volume, the second film is smaller than the first film and is easier to separate, so the mechanical arm only needs to drive the vibration motor to slowly move upward by a certain distance to achieve the effect of partially separating the second film from the vibration motor, without the need to separate by rotating, which simplifies the structure, the mechanical arm drives the vibration motor to slowly move upward to separate the second film and the vibration motor into an opening, so that in the subsequent film tearing process, the second film can be separated from the vibration motor along the opening, reducing the possibility of the second film being pulled off, then the second clamping mechanism 10 releases the second film,The second film is blown away from the automatic rotating film tearing mechanism by the air nozzle, and then the mechanical arm can drive the wireless charging coil and the vibration motor to move to the assembly station, so as to realize the automatic film tearing of the wireless charging coil and the vibration motor.

[0034] Using the automatic rotating film tearing mechanism in the embodiment, the degree of automation is high.
