Description

Technical Field

[0001] The present application relates to the technical field of copper foil peeling equipment, and in particular to a roll-to-roll copper foil peeling machine. Background Art

[0002] In the production process of flexible printed circuit boards, in order to improve the processing efficiency of copper foil, two rolls of copper foil are pressed together through a pressing device, so that two sheets of copper foil can be processed at one time. After the processing is completed, the two pressed copper foils need to be torn apart so that the copper foils can be used separately.

[0003] When using a copper foil tearing machine to tear off the laminated copper foil, the torn upper copper foil, tape layer and lower copper foil are actively wound up by the winding shaft. Since the tape layer has a certain elastic force, the tape winding shaft will generate a certain pulling force on the tape layer during the process of winding up the tape layer. During the stretching of the tape layer, the edge position and the middle position of the tape layer will produce a large tensile deformation due to different forces, resulting in the tape layer being thick in the middle and thin on both sides. After the stretched tape layer is wound up, there are gaps between the tapes of the tape roll, the combination is not tight, and relative sliding is prone to occur, thereby affecting the winding of the tape layer by the tape winding shaft.

[0027] The working principle of the present invention is as follows: See also Figure 1 Before using the roll-to-roll copper foil tearing machine to tear off the bonded copper foil, it is necessary to place the bonded copper foil rolls on the unwinding roller 201, and one end of the bonded copper foil rolls passes through the receiving platform 202 and between the two guide rollers 6. The bonded copper foil passing through the two guide rollers 6 is separated into an upper copper foil, a tape and a lower copper foil. The upper copper foil passes through the constant tension seat I 302 and is wound around the upper copper foil roller 301, and the upper copper foil is rolled up by the upper copper foil roller 301. The tape passes through the conveying structure 7 and the constant tension seat II 402. The two conveying rollers 703 of the conveying structure 7 are close to the upper and lower sides of the tape. The tape passing through the conveying structure 7 and the constant tension seat II 402 is wound around the tape roller 401, and the tape is rolled up by the tape roller 401. The lower copper foil passes through the constant tension seat III 502 and is wound around the lower copper foil roller 501, and the upper copper foil is rolled up by the lower copper foil roller 501.

[0028] See also Figure 1-Figure 6 During the working process, the tearing machine is controlled by the control system 8. When the tape passes through the two conveying rollers 703 of the conveying structure 7, the power device of the conveying roller 703 is started, and the power device drives the conveying roller 703 to rotate. Since the transmission gears 704 on the two conveying rollers 703 are engaged, the two conveying rollers 703 rotate in opposite directions, so that the two conveying rollers 703 squeeze the tape while driving the conveying roller 703 to move toward one end of the constant tension seat II 402, thereby reducing the tension of the tape between the tape roller 401 and the conveying structure 7, preventing the tape from being subjected to tension when the tape roller 401 is winding up, resulting in a phenomenon that the middle is thick and the two sides are thin, thereby avoiding the problem of gaps between the tapes collected by the tape roll by the tape roller 401, which is prone to relative sliding.

[0029] See also Figure 1-Figure 6In the process of the power device driving the conveying roller 703 to rotate, when the buffer hole on the conveying roller 703 is opposite to the connecting hole 708, the permanent magnet block embedded on the side wall of the connecting hole 708 and the sealing slider 707 generate a mutually repelling magnetic force, and the permanent magnet block embedded on the side wall of the connecting hole 708 pushes the sealing slider 707 to squeeze the supporting spring 706, so that the sealing slider 707 slides into the buffer hole. In this process, negative pressure is generated in the buffer hole, so that the negative pressure in the buffer hole passes through the connecting hole 708, the middle groove 705, the oil pipe, the rotary joint II 603, the guide The heat hole 601, the rotary joint I 602 and the connecting pipe I 604 absorb the high-temperature heating oil in the heating box 9, and the heating oil enters the heat-conducting hole 601 of the guide roller 6, thereby heating the outer wall of the guide roller 6. After the temperature of the guide roller 6 rises, the copper foil roll bonded between the two guide rollers 6 is heated by the guide roller 6, thereby reducing the adhesion of the tape layer of the copper foil roll, reducing the pulling force of the upper copper foil structure 3, the tape structure 4 and the lower copper foil structure 5 on the upper copper foil, the tape and the lower copper foil, and preventing the deformation and damage of the copper foil in the process of tearing off the copper foil.

[0030] See also Figure 1-Figure 6 When the adhesive force between the adhesive tape and the copper foil is large and difficult to tear apart, the adhesive tape will move with the copper foil on one side, and the adhesive tape moving with the copper foil will move up or down. At this time, the adhesive tape will push the conveying roller 703 and the supporting slider 702 on the supporting frame 701 on one side to slide into the middle groove 705, so that the supporting slider 702 entering the middle groove 705 squeezes the heating oil in the middle groove 705, and the heating oil finally pushes the auxiliary block 711 and the auxiliary scraper 712 to move toward the bonding point between the copper foil and the adhesive tape, so that the auxiliary scraper 712 scrapes and separates the bonding point between the copper foil and the adhesive tape, thereby preventing the adhesive tape from moving with the copper foil due to excessive adhesive force between the adhesive tape and the copper foil.
