[0032] The left and right sides of the horizontal straight single-sided tape 9a on the tape folding platform 36 of the second folding portion 3b are respectively and parallelly provided with a first folding push strip 15 and a second folding push strip 16, and the distance between the lower surface of the first folding push strip 15 and the second folding push strip 16 and the upper surface of the tape folding platform 36 is just twice the thickness of the horizontal straight single-sided tape 9a; the first folding push strip 15 and the second folding push strip 16 are vertically connected to the side away from each other with a first horizontal telescopic push rod 63a and a second telescopic push rod 63b; driven by the first telescopic push rod 63a and the second telescopic push rod 63b, the first folding push strip 15 and the second folding push strip 16 move towards and away from each other.

[0033] The horizontal straight single-sided tape 9a at the folded tape rolling part 2 and the folded copper foil tape winding part 1 is a folded copper foil tape 9b. The folded tape rolling part 2 includes an upper rolling wheel 7a and a lower rolling wheel 7b distributed up and down. The upper rolling wheel 7a and the lower rolling wheel 7b roll and clamp the upper and lower sides of the folded copper foil tape 9b.

[0034] Process and working principle:

[0035] like Figure 3, the tape storage roll of the tape storage roll lead-out section 6 leads out the horizontal straight line single-sided tape 9a with the adhesive surface facing upward at a predetermined rhythm, and at the same time, the folded copper foil tape reeling section 1 performs the reeling and storage action at a corresponding rhythm, so that any local section on the horizontal straight line single-sided tape 9a led out from the tape storage roll lead-out section 6 passes through the copper foil pasting section 5, the tape edge cutting section 71, the copper foil rolling section 4, the tape edge folding section 3 and the folded tape rolling section 2 in sequence along its own extension direction, and is finally reeled and stored by the folded copper foil tape reeling section 1;

[0036] When a partial section of the horizontal straight single-sided tape 9a reaches the copper foil pasting portion 5, the robot or manual station at the copper foil pasting portion 5 pastes a rectangular copper foil 8 on the upper surface of the horizontal straight single-sided tape 9a in the center, and then the rectangular copper foil 8 moves synchronously with the partial section of the horizontal straight single-sided tape 9a;

[0037] When the rectangular copper foil 8 moves along with the horizontal straight single-sided tape 9a to pass through the tape edge cutting portion 71, the front side and the rear side of the rectangular copper foil 8 pass directly under the knife holder 10 in sequence. When the front side and the rear side of the rectangular copper foil 8 pass directly under the knife holder 10 respectively, the knife holder 10 is controlled to drive the two cutters 11 downward to perform a cutting action; thereby, the two edges of the horizontal straight single-sided tape 9a at the front and rear positions of the rectangular copper foil 8 are symmetrically cut into two cutting seams 26 perpendicular to the length direction of the horizontal straight single-sided tape 9a;

[0038] When the rectangular copper foil 8 moves to the copper foil sheet rolling portion 4 along with the horizontal straight line single-sided adhesive tape 9a, the rolling wheel 25 centrally rolls the rectangular copper foil 8, so that the rectangular copper foil 8 is more tightly bonded to the surface of the horizontal straight line single-sided adhesive tape 9a;

[0039] When the rectangular copper foil 8 moves along with the horizontal straight line single-sided adhesive tape 9a to the first folding portion 3a of the adhesive tape edge folding portion 3, as shown in FIG. Figure 6 , the rectangular copper foil 8 is just centered above the straight groove 33. At this time, the lead-out of the tape storage roll lead-out part 6 and the reeling of the folded copper foil tape reeling part 1 are first suspended; the control driving device drives the moving bracket 13 to drive the folding and rolling wheel 25 to move downward until it contacts the surface of the rectangular copper foil 8 and continues to descend, so that the folding and rolling wheel 25 presses the rectangular copper foil 8 at its position to the bottom of the straight groove 33, and the lower part of the folding and rolling wheel 25 is stuck in the straight groove 33, and then the moving bracket 13 moves forward and backward, so that the folding and rolling wheel 25 rolls forward and backward along the length direction of the straight groove 33, so that any position of the rectangular copper foil 8 is rolled to the bottom of the straight groove 33, and the horizontal straight single-sided tape 9a on the left and right sides of the rectangular copper foil 8 is folded upward under the constraint of the inner wall surfaces 33b on both sides of the straight groove 33 to form left and right symmetrical vertical left folding tape pieces 40a and right folding tape pieces 40b, as shown in FIG. Figure 7; Then the moving bracket 13 drives the folding roller 25 to move upward to disengage the linear groove 33; then the lead-out of the tape storage roll lead-out portion 6 and the reeling of the folded copper foil tape reeling portion 1 continue to be executed;

[0040] When the rectangular copper foil 8 moves to the second folding portion 3b of the folding portion 3 of the tape edge along the horizontal straight line single-sided tape 9a, the first telescopic push rod 63a is first controlled to extend, driving the first folding push strip 15 to move close to the second folding push strip 16, so that the first folding push strip 15 pushes the left folding tape piece 40a to fold downward toward one side of the rectangular copper foil 8 until the adhesive surface of the left folding tape piece 40a is parallel to and adhered to the upper surface of the rectangular copper foil 8, and then the first telescopic push rod 63a is immediately controlled to retract and drive the left folding tape piece 40a to the initial position; then the second telescopic push rod 63b is controlled to extend, driving the first telescopic push rod 63a to move closer to the second folding push strip 16, so that the first folding push strip 15 pushes the left folding tape piece 40a to fold downward toward one side of the rectangular copper foil 8, until the adhesive surface of the left folding tape piece 40a is parallel to and adhered to the upper surface of the rectangular copper foil 8, and then the first telescopic push rod 63a is immediately controlled to retract and drive the left folding tape piece 40a to the initial position; The second folding push strip 16 moves close to the first folding push strip 15, so that the second folding push strip 16 pushes the right folding tape piece 40b to be folded downward toward one side of the rectangular copper foil 8, until the adhesive surface of the right folding tape piece 40b is parallel and bonded to the upper surface of the rectangular copper foil 8, and then the second telescopic push rod 63b is immediately controlled to retract and drive the right folding tape piece 40b to the initial position; at this time, the folding and bonding process of the left folding tape piece 40a and the right folding tape piece 40b is completed, and at this time, the horizontal straight line single-sided tape 9a at the second section folding portion 3b of the tape edge folding portion 3 becomes the folded copper foil-containing tape 9b;

[0041] Then, the folded copper foil tape 9b continues to run along its own extension direction toward the folded copper foil tape reeling portion 1. When the folded copper foil tape 9b passes through the folded tape rolling portion 2, the folded copper foil tape 9b is clamped by the upper rolling wheel 7a and the lower rolling wheel 7b, so that the left folded tape piece 40a and the right folded tape piece 40b on the folded copper foil tape 9b are more tightly bonded to the upper surface of the rectangular copper foil 8.

[0042] Finally, the folded copper foil tape 9b is rolled up and stored by the winding device of the folded copper foil tape winding unit 1. The folded copper foil tape 9b rolled up and stored by the winding device of the folded copper foil tape winding unit 1 has a plurality of cut marks 26a distributed evenly along the length direction.

[0043] When the target copper foil adhesive tape 9c is needed, the folded copper foil adhesive tape 9b stored by the reeling device of the folded copper foil adhesive tape reeling unit 1 is cut along the plurality of cut marks 26a to obtain a plurality of target copper foil adhesive tapes 9c.

[0044] The transformer to which the copper foil tape of the adhesive folding process system of the adhesive copper foil is applied includes an assembly structure of an IE type transformer core 50 and a coil frame 51 on which a coil has been wound. The target copper foil adhesive 9c is tied and wound around the outside of the assembly structure of the IE type transformer core 50 and the coil frame 51 on which a coil has been wound with the cooperation of an adhesive, thereby enveloping the coil outside the coil frame 51 to play an electromagnetic shielding role.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
