Description

Technical Field

[0001] The present invention belongs to the field of copper foil with adhesive backing, and particularly relates to a copper-retaining adhesive machine. Background Art

[0002] In the production of existing electronic transformers and magnetic ring inductors, copper strips (usually with a thickness of more than 0.1 mm) used as windings or copper foil strips (usually with a thickness of 0.1 mm and below) used for shielding generally need to be pasted with Marley tapes, high-temperature tapes or non-woven tapes on the surface for insulation. However, usually a part of both ends of the copper strip or copper foil strip is exposed, which is used as the PIN of the electronic transformer (winding) or the welding surface for the head and tail connection of the copper foil strip (shielding).

[0003] However, there are usually two existing methods for realizing the exposed copper strip:

[0004] One is to cut the tape manually, then paste the tapes at intervals on the surface of the copper strip one by one, and then cut the copper foil, but the efficiency is very slow.

[0005] The other is to paste the tape on the surface of the copper strip by machine and then cut the copper foil. At this time, the length of the copper foil is the same as that of the tape. Then, cut the tape at both ends of the copper strip and peel off the tape to expose the copper. This method wastes tape, has low efficiency and is easy to scratch the copper foil. And this method can only be applied to copper strips with a thickness of more than 0.1 mm. If the copper strip with a thickness of less than 0.1 mm is used, there is a risk of cutting off the copper strip, and only the above-mentioned manual cutting method can be adopted.

The tape winding shaft 6 is rotatably arranged in the machine table 1. The chassis 7 is arranged on the top of the machine table 1. The pressing tape drive device 8 is arranged on the top of the chassis 7. The pressing tape rubber head 9 is arranged at the bottom of the drive end of the pressing tape drive device 8, and the pressing tape rubber head 9 is located above the copper tape conveying path.

The two rubber clamping chucks 14 are arranged at the top of the drive end of the rubber clamping drive device 13, and the two rubber clamping chucks 14 are clamped on the top of the rotary frame 11.

[0028] Specifically, a welding lead threading sleeve device 16 is arranged on the machine table. The welding lead threading sleeve device 16 is adjacent to the starting end of the copper tape conveying path. The welding lead threading sleeve device 16 is a common and general existing device for welding leads of copper foil wires and threading sleeves, and is used for welding copper foil wires on one side of the copper tape and then threading sleeves.

[0029] Specifically, the copper tape conveying mechanism further includes a rolling wheel 17. The rolling wheel 17 is rotatably arranged on one side of the traction frame 3, and the rolling wheel 17 is in rolling contact with the traction wheel 5. The rolling wheel 17 rotates driven by the traction wheel 5, and the cooperation between the two is more convenient for pulling the copper tape to move, and at the same time, it can further press the copper tape and the tape adhered to its bottom.

When the adhesive tape is bonded to the copper tape, the adhesive tape pressing driving device 8 drives the adhesive tape pressing head 9 to press down to firmly bond the adhesive tape to the copper tape. The limiting block 22 moves along with the adhesive tape pressing head 9. When the limiting block 22 touches the top of the rotating frame 11, it restricts the adhesive tape pressing head 9 from continuing to move downwards to avoid damaging the copper tape.

[0033] Specifically, the adhesive cutting and copper-retaining mechanism further includes a guiding wheel 23; the guiding wheel 23 is rotatably arranged on one side of the bottom frame 7; the guiding wheel 23 is located below the copper tape release shaft 2 and the rotating frame 11.

[0035] Specifically, the adhesive cutting and copper-retaining mechanism further includes a synchronizing block 27 and an adjusting screw 28; the synchronizing block 27 is arranged on one side of the first lifting block 24; the adjusting screw 28 is rotatably arranged on the synchronizing block 27, and one end of the adjusting screw 28 is threadedly engaged in one of the adhesive clamping heads 14.

[0036] Specifically, the rubber cutting and copper remaining mechanism further includes a second lifting block 29; the second lifting block 29 is arranged at the top of the lifting end of the rubber cutting driving device 13; a clamping groove 30 is arranged on the second lifting block 29; the bottom of the rubber cutting blade 15 is press-fitted and slidably inserted into the clamping groove 30 from one side. The replacement of the rubber cutting blade 15 is very convenient.

[0037] The working process of the present invention:

[0038] Preparation work: Manually pull one end of the copper strip on the copper strip release shaft 2 to pass between the traction wheel 5 and the rolling wheel 17. During subsequent work, the traction driving device 4 drives the traction wheel 5 to rotate, so that the copper strip continuously moves along the copper strip conveying path; Manually pull one end of the adhesive tape on the adhesive tape winding shaft 6 to pass through the guiding wheel 23, and then bond one end of the adhesive tape to the bottom of the copper strip. During subsequent work, the adhesive tape will slide past the top of the rotating frame 11 driven by the copper strip.

[0039] Production work: The traction driving device 4 drives the copper strip to move. After one end of the adhesive tape is bonded to the copper strip, the subsequent part of the adhesive tape passes through the top of the rotating frame 11 driven by the copper strip. When passing through, the adhesive tape is continuously bonded to the copper strip under the clamping of the rotating frame 11 and the adhesive tape pressing rubber head 9. When the bonded adhesive tape passes through a set distance, the traction driving device 4 is turned off. At the same time, the rotation driving device 10 drives the rotating frame 11 to rotate, so that the rubber clamping chuck 14 approaches the guiding wheel 23. Then the rubber clamping driving device 12 drives the rubber clamping chuck 14 to drop to clamp the adhesive tape between the guiding wheel 23 and the copper strip. At the same time, the rubber cutting driving device 13 drives the rubber cutting blade 15 to lift up to cut the adhesive tape between the rubber clamping chuck 14 and the copper strip from one side of the rubber clamping chuck 14, and then the rubber cutting blade 15 resets; Then the traction driving device 4 starts, driving the copper strip to continue to move forward, so that the adhesive tape disconnected from the rubber clamping chuck 14 passes through the rotating frame 11 driven by the copper strip and is bonded to the bottom of the copper strip under the clamping of the adhesive tape pressing rubber head 9 and the rotating frame 11 (the top surface of the rotating frame 11 is semi-circular, and after rotation, the top surface still supports the bottom of the copper strip). Until the bonded adhesive tape continues to move through a set distance, the traction driving device 4 is turned off. At this time, the rotation driving device 10 drives the rotating frame 11 to reset, and the rubber clamping chuck 14 pulls one end of the adhesive tape to bond it to the bottom of the copper strip. Finally, the rubber clamping driving device 12 drives the rubber clamping chuck 14 to lift up to release the adhesive tape, and the traction driving device 4 restarts to drive the copper strip to move. At this time, the subsequent adhesive tape is separated from the previous adhesive tape by a set distance, and the copper strip between the adhesive tapes is the part that needs to be exposed. The subsequent work repeats the above steps.

[0040] Specifically, as a preferred embodiment of the present invention, the traction driving device 4 is a motor, and the rotation driving device 10, the rubber clamping driving device 12, the rubber cutting driving device 13 and the cutting driving device 19 are cylinders.

[0041] As can be seen from the above description, the present invention can achieve cutting the adhesive tape to expose the copper tape without wasting the adhesive tape and damaging the copper tape.

[0042] The preferred embodiments of the present invention have been described in detail in conjunction with the accompanying drawings of the specification. It should be noted that the protection scope of the present invention includes but is not limited to the above embodiments; the specific structures disclosed in the accompanying drawings of the specification are also only the preferred embodiments of the present invention.
