After the winding of the coils of new energy electronic transformers is completed, the outer film coating of each wire head reserved in the coil must be stripped, and then tinned for welding the PCB board to form the finished product. The existing technology for stripping the outer coating of the film-coated wire is: 1. Traditional stripping machine, the defect is that it cannot guarantee the cutting depth and cause damage to the internal conductor; 2. Use a utility knife to manually ring-cut the film-coated wire, and then soak it in a chemical diluent to soften the outer coating of the film-coated wire, and then take it out and pull it out manually. The disadvantage of this method is that it is difficult for personnel to operate and the efficiency is low. 3.

The invention can automatically cut the outer membrane layer of the film-coated wire and realize the movement of the outer membrane layer from the ring cutting position. The operation process does not damage the internal conductor, but the device structure is complicated. Utility Model Content

DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can easily implement the present invention.

[0016] like Figure 1 As shown, a simple film-coated wire stripping device includes a base 1 and a stripping vertical plate 2 above the base 1.

[0017] like Figure 2-3As shown, the base 1 is provided with a dovetail groove 3 running through both ends of the base; the stripping vertical plate 2 is composed of a U-shaped alloy vertical plate and two blades 4; the bottom of the U-shaped alloy vertical plate is processed into a dovetail bottom 5 matching the dovetail groove 3 of the base 1, and the bottom of the U-shaped alloy vertical plate is inserted into the dovetail groove 3 of the base 1 and connected to each other; the vertical edges 6 on both sides of the U-shaped alloy vertical plate are symmetrical, and the upper part of each vertical edge 6 is provided with a clamping groove 7 running through the left and right directions, and the groove ends of the clamping grooves 7 of the two vertical edges 6 are close to each other and maintained on the same straight line; at the groove end positions of the clamping grooves 7 where the two vertical edges 6 are close to each other, each clamps a blade 4, and the blades 4 clamped by the two clamping grooves 7 are in a directly opposite state and form a stripping gap; each of the clamping grooves 7 has a groove edge on which a locking hole 8 with an internal thread is provided at the position corresponding to the clamping blade 4, and a locking screw 9 is installed on the locking hole 8 to press and support the blade 4;

[0018] Two upper and lower adjustment holes 10 with internal threads are provided at the other end of each clamping groove 7 opposite to the blade 4. The adjustment hole 10 with internal threads has an adjustment screw 11 that can adjust the clamping depth of the blade 4 to change the width of the stripping gap, thereby achieving the stripping gap position to adapt to the process requirements of different membrane wire sizes.

[0019] Furthermore, the starting portion of the blade of the blade 4 has an arc chamfer, and the blades of the two blades 4 are combined to form a gap with a trumpet mouth at the starting portion, which is convenient for guiding the film-wrapped wire into the stripping gap.

[0020] When in use, first install the two blades 4 on the clamping grooves 7 of the two vertical sides 6 of the U-shaped alloy vertical plate respectively, adjust the clamping depth of the two blades 4 according to the conductor size of the film-wrapped wire to be processed, so that the blade parts of the two blades 4 are exposed in the clamping groove 7, and tighten the locking screws 9 to lock the blades 4 without displacement; carefully adjust the upper and lower adjustment screws 11 on both sides to keep the blade parts of the two blades 4 parallel and facing each other, forming a stripping gap slightly larger than the conductor size of the film-wrapped wire to be processed; then, the wire head of the film-wrapped wire to be processed is entered into the stripping gap along the trumpet formed at the starting position of the two blades 4. In the process of entering the stripping gap, as the wire head of the film-wrapped wire to be processed is pressed downward, the trumpet entering the stripping gap becomes smaller, and the cutting depth of the blades of the two blades 4 cutting the outer membrane coating of the film-wrapped wire to be processed becomes larger. Until entering the parallel stripping gap section, the cutting depth of the blades of the two blades 4 no longer increases; at this time, the film-covered wire to be processed is pulled out, and the outer film coating of the wire head end is blocked by the blades of the two blades 4 and separated from the conductor of the film-covered wire to be processed; the film-covered wire stripping is completed. Since the width of the blades of the two blades 4 is slightly larger than the size of the conductor of the film-covered wire to be processed, the cutting depth of the blades is always less than the thickness of the outer film coating of the film-covered wire, and the blades will not damage the internal conductor.

[0021] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the scope of the claims of the utility model shall be within the scope of protection of the utility model.
