[0040] Movement process: first, the workpiece 9 is placed at the feeding end of the feeding streamline 1, and the feeding streamline 1 drives the workpiece 9 to move to the discharging end of the feeding streamline 1.

At this time, the first light source 11 and the second light source 22 are started to illuminate the workpiece 9, and the camera 23 captures the position of the workpiece 9. Then, the first robot arm 31 drives the suction cup 33 and the four first clamping cylinders 34 to move to the top of the workpiece 9. The suction cup 33 sucks the workpiece body, and the four first clamping cylinders 34 clamp the four wires of the workpiece. Then, the first robot arm 31 drives the workpiece to move to the carrier 4 located at the first end of the carrier streamline. At this time, the workpiece body is placed in the positioning groove, and the lifting cylinder 42 drives the top block 43 Move upward, because the top block 43 is narrow at the top and wide at the bottom, the top block 43 can separate the two clamping blocks from each other when squeezing the two first rollers. At this time, the two clamping blocks are away from each other, and the wire can be inserted between the two clamping blocks. Then the lifting cylinder 42 descends, and the two clamping blocks are driven by the elastic force of the tension spring to approach each other and clamp the wire to fix the workpiece 9. Then the carrier 4 and the workpiece 9 are driven by the carrier streamline 8 to move to the positioning module 5. Then the lifting cylinder 42 rises to separate the two clamping blocks. At this time, the wire is in an active state, and the push-pull cylinder 53 drives the second clamping cylinder 52 to extend, and the second clamping cylinder 52 clamps the wire. The push-pull cylinder 53 retracts and adjusts the position of the wire, and then the second clamping cylinder 52 releases the wire. The push-pull cylinder 53 and the lifting cylinder 42 are reset to complete the adjustment of the wire position, and then the carrier streamline 8 drives the carrier 4 and the workpiece 9 to move to the film tearing module 6, and then the lifting cylinder 42 rises to separate the two clamping blocks. At this time, the wire is active again, and the telescopic cylinder 61 extends. At this time, the wire extends between the two abutments 64 and the film tearing knife 65. The film tearing knife 65 approaches and squeezes the protective film of the wire under the drive of the film tearing cylinder, and then the motor drives the rotating shaft 63 to rotate, and the two abutments 64 and the film tearing knife 65 also rotate together. At this time, the film tearing knife 65 peels off the protective film on the surface of the wire, and the second photoelectric sensor 66 confirms that the protective film on the wire is peeled off. The second roller can provide abutment for the wire to prevent the wire from being damaged. The negative pressure suction barrel absorbs the peeled protective film. After the film tearing is completed, the film tearing cylinder is reset to release the wire, the telescopic cylinder 62 is retracted, the lifting cylinder 42 is reset, and the wire is re-fixed. Then the carrier 4 and the workpiece 9 are moved to the unloading mechanism 7 driven by the carrier streamline, the lifting cylinder 42 rises, and the wire is active again. The second robot arm 71 drives the two third clamping cylinders 73 and the two fourth clamping cylinders 74 to move to the top of the workpiece 9. The two third clamping cylinders 73 clamp the workpiece body, and the two fourth clamping cylinders 74 clamp the wire to fix the workpiece 9. Then the workpiece 9 is moved to the unloading position driven by the second robot arm 71. At this time, all the film tearing processes are completed and the workpiece 9 can undergo subsequent processing.

[0041] The use of the protective film stripping device in this embodiment has the advantages of high automation, high stripping efficiency and good stripping effect.
