[0002] Die-cut components are widely used in electronic products or equipment. Some electronic devices require the use of composite conductive components including conductive double-sided tape and conductive cloth to meet the needs of component bonding, conductivity, and electromagnetic shielding. The price of conductive double-sided tape is more expensive than other raw materials. When producing certain irregular double-sided tape components, it is necessary to save materials and reduce costs. The conventional solution is to cut the rolled double-sided tape raw material into rolls of smaller width, and then unroll it along the direction of the production tape for die cutting. However, in this solution, the material in the gap between the edges of the contours of two adjacent products will become waste, resulting in a lot of waste of conductive double-sided tape materials. Summary of the invention

[0005] The production process of the conductive double-sided adhesive assembly is carried out using a high-speed rotary die-cutting machine, which includes the following steps:

[0006] Step a, performing a first asynchronous die-cutting on the first product release film material strip and the first conductive double-sided adhesive material strip by a first asynchronous die-cutting roller group, while cutting out the contour lines of the first product release film and the first conductive double-sided adhesive contour facing the inside of the product, and forming the first product release film semi-finished product and the first conductive double-sided adhesive semi-finished product on the material strip at equal intervals, and at the same time cutting out the contour line of the handle end of the first product release film parallel to the traveling direction of the material strip, and discharging waste;

[0011] Further, step a is specifically as follows: compounding the first conductive double-sided adhesive tape with the first product release film tape and the first transition bottom film tape in sequence, peeling off the first conductive double-sided adhesive tape from the top and then compounding with the first transition release film tape, performing the first asynchronous die-cutting through the first asynchronous die-cutting roller group and removing the first transition bottom film tape, the first asynchronous die-cutting causes the first product release film tape and the first conductive double-sided adhesive tape to be cut into segments and arranged at equal intervals on the first bottom film tape, and forming the contour line of the handle end of the first product release film; then, the first transition release film tape and the transition release film waste on the first conductive double-sided adhesive block are removed through the first row of waste tapes, at this time, the main tapes are the first bottom film tape, the first release film block arranged at intervals on the first bottom film tape, and the first conductive double-sided adhesive block from bottom to top;

[0013] Step c is specifically as follows: at the upper rear of the running direction of the main material tape, the second conductive double-sided adhesive tape is compounded with the second transition release film tape, the self-contained film below the second conductive double-sided adhesive tape is peeled off, the material is fed in the opposite direction of the running of the main material tape, and at the same time, the third transition release film tape is fed from the bottom in the same direction, and the second asynchronous die-cutting is performed by the second asynchronous die-cutting roller group. The second asynchronous die-cutting cuts the second process release film tape and the second conductive double-sided adhesive tape into segments and arranges them on the third transition release film tape at equal intervals, and then the second transition release film tape and the second conductive double-sided adhesive tape are removed by the second waste tape discharger. The waste of transition release film on the surface adhesive block is then flipped by the first flip roller to be compounded with the main material strip from step b, and the compounded position of the second conductive double-sided adhesive block forms a staggered interval with the first conductive double-sided adhesive block, and the interval distance is the gap width.

[0014] Step d is specifically as follows: the main material strip after step c is synchronously die-cut by the third die-cutting roller group, and the synchronous die-cutting punches out the outer contour of the conductive cloth layer and the outer contour line of the first conductive double-sided adhesive layer and the outer contour line of the second conductive double-sided adhesive layer that match the outer contour of the conductive cloth layer, and die-cuts out the outer contour line of the first product release film and its handle part, and the outer contour line of the handle part intersects with the handle part end contour line formed in step a to form a handle part, and the die-cutting depth of the third die-cutting roller group at the handle part does not cut through the first product release film, only cuts off the first conductive double-sided adhesive block, and the die-cutting depth of the remaining parts just cuts through the first product release film; then, the waste outside the frame of the third transition release film strip and the waste outside the frame of the second conductive double-sided adhesive block other than the conductive cloth layer contour line are excluded. The waste outside the conductive cloth tape frame is removed, and the waste outside the conductive cloth tape frame is removed, and the waste of the third transition release film located within the outline frame of the conductive cloth layer is removed through the third row of waste tapes, and then the fourth row of waste tapes and the second product release film tape are compounded from the top, and the fourth row of waste tapes does not touch the area within the conductive cloth layer, but only touches the first conductive double-sided adhesive waste and the first product release film waste and the first bottom film tape outside the conductive cloth layer, and then the first bottom film tape, the waste outside the first conductive double-sided adhesive frame, the waste outside the first product release film frame and the fourth row of waste tapes are removed from the bottom; at this time, the tapes are from top to bottom: the second product release film tape, the second conductive double-sided adhesive layer, the conductive cloth layer, the first conductive double-sided adhesive layer, the first product release film; that is, the product is transferred to the second product release film tape;

[0015] Step e is specifically as follows: compound the shipping protection film tape and the second bottom film tape in sequence from the bottom, cut them by the fourth die-cutting roller group, cut off the second product release film tape and the shipping protection film tape from the position between adjacent products, and then peel off the second bottom film tape, collect the materials to obtain the finished product, which includes the shipping protection film, the first product release film, the first conductive double-sided adhesive layer, the conductive cloth layer, the second conductive double-sided adhesive layer, and the second product release film from bottom to top.

[0016] Furthermore, in step a, the number of the first conductive double-sided adhesive tapes is more than two, which are compounded in parallel with the first product release film tape, and correspondingly, the knife roller of the first asynchronous die-cutting roller group has a first straight blade line for cutting the more than two first conductive double-sided adhesive tapes and more than two handle end contour line blades;

At this time, the main material tapes are, from bottom to top, the first base film tape T2, the first release film block arranged at intervals on the first base film tape T2, and the first conductive double-sided adhesive block; the distance between adjacent first release film blocks and first conductive double-sided adhesive blocks is controlled according to the width of the gap 11 and the width of the second conductive double-sided adhesive layer 3, so that the second conductive double-sided adhesive layer 3 can be staggered and the gap 11 can be formed;

[0030] Step c, at the upper rear of the main material belt running direction, compound the second conductive double-sided adhesive tape J2 and the second transition release film tape G2, peel off the second conductive double-sided adhesive tape self-contained film J21 below, feed in the opposite direction of the main material belt running, and feed the third transition release film tape G3 from the bottom in the same direction, and perform the second asynchronous die-cutting through the second asynchronous die-cutting roller group M2. The number of the second conductive double-sided adhesive tape J2 is the same as the number of the first conductive double-sided adhesive tape, that is, it is also two, and the knife roller of the second asynchronous die-cutting roller group M2 has a second straight line blade R201 for cutting the second conductive double-sided adhesive tape J2; the second asynchronous die-cutting causes the second process release film tape G2 and the second conductive double-sided adhesive tape J2 to be cut into segments and arranged at equal intervals to the third The transition release film tape G3 is then removed through the second row of waste tapes P2 to remove the second transition release film tape G2 and the transition release film waste on the second conductive double-sided adhesive block, and then the tape is flipped by the first flip roller Z1 to be compounded with the main tape from step b, and the position where the second conductive double-sided adhesive block is compounded forms a staggered interval with the first conductive double-sided adhesive block, and the interval distance is the gap width.

Therefore, the process of the present invention is reduced and the difficulty of alignment is reduced, while the traditional process segmentation and alignment processes are more complicated and cumbersome; the hatched part in the figure is the conductive double-sided adhesive waste generated. The conductive double-sided adhesive material required by the process of the present invention is actually saved by about 30%-50% compared with the conductive double-sided adhesive material required by the traditional die-cutting waste discharge process.

[0034] In summary, the present invention adopts the above-mentioned process, and by accurately controlling the mold step distance and the material belt travel speed, the conductive double-sided adhesive raw materials on the front and back sides are asynchronously cut into shapes of specified sizes, and at the same time, the contour line on one side is formed and falls at intervals at the specified positions of the conductive fabric belt, which optimizes the processing steps, reduces the number of required molds, and avoids the consumption of conductive double-sided adhesive materials in the gap part of the product, thereby reducing the processing cost and effectively improving the material utilization rate.
