Technical Field

[0001] The utility model relates to the technical field of metal mesh touch sensor preparation, in particular to a roll-to-roll roller and a device for preventing metal mesh touch sensors from being scratched. Background Art

[0002] Metal mesh touch sensors offer the advantages of high flexibility and low cost. They form metal circuits on a substrate through a series of processes, including coating, exposure, development, copper plating, and blackening. This product is produced using roll-to-roll manufacturing technology, a core principle of which is to refine the flexible substrate through continuous transfer of material between two active rolls. Compared to traditional sheet-to-sheet, sheet-to-roll, and roll-to-sheet methods, this technology demonstrates significant potential for manufacturing flexible electronic devices, solar panels, printed circuit films, thin-film batteries, and other applications.

[0003] Because the minimum surface width of this product can be less than 5μm, direct contact between any surface and the guide rollers during the integrated wet process carries a high risk of damaging the lines. Wet roll-to-roll production equipment uses rollers for transport, and product contact with the rollers can lead to defects such as scratches, scrapes, and peeling. These defects are primarily concentrated in the trace area and can severely impact product functional yield. For example, Chinese utility model patent No. CN218372559U discloses a roll-to-roll metallization device with a spray mechanism, the roller transport mechanism of which may pose this risk.

[0004] Therefore, wet roll-to-roll production equipment transmits products through rollers, and defects such as scratches, scrapes, and peeling may occur in the process of product contact with the rollers. These defects are mainly concentrated in the product routing area and will seriously affect the functional yield of the product. In order to solve the defects and improve the product yield, the existing roller structure is redesigned and modified. Utility Model Content

Figure 1-3 , including a roller body 1, the roller body 1 is cylindrical, and a groove 2 is provided on the roller body 1, the groove 2 includes a common groove 21 and a plurality of matching grooves 22, the common groove 21 and a matching groove 22 are matched to correspond to a product size; the groove 2 is arranged opposite to the wiring area 4 on the production roll 3 used for preparing the metal mesh touch sensor, and the roller body 1 does not contact the wiring area 4 when rotating.

[0033] As an optional solution, the groove 2 is an annular groove. As an optional solution, the width of the groove 2 is set to 40-60 mm. As an optional solution, the depth of the groove 2 is 6-10 mm. Preferably, the depth of the groove 2 is 8 mm. As an optional solution, the number of the grooves 2 is set to 3, including 1 common groove 21 and 2 matching grooves 22, the common groove 21 is 50 mm long; the matching grooves 22 are 60 mm and 40 mm long respectively; the length from one end of the roller body 1 close to the common groove 21 to the farthest section of the matching groove close to the common groove 21 is 450 mm; the length from the other end of the roller body 1 is 600 mm.

[0034] As an optional solution, the end of the roller body 1 is provided with a connecting groove 6 that can cooperate with the bearing.

[0035] As an optional solution, the material of the roller body 1 is U-PE.

[0036] In the specific implementation process, a sensor 9 is vertically arranged on the production roll. In the actual mass production, the sensor 9 is arranged along the roll-to-roll transmission direction ( Figure 3 Two sensors 9 are placed symmetrically in each row (direction of the arrow), with their edges aligned. The wiring area 4 is located on all four sides of the sensor 9, with the scratch-resistant side being the upper side of the sensor 9 (the side with denser wiring). When using the roll-to-roll roller for preventing scratches on metal mesh touch sensors, the roller body 1 is provided with a groove 2, which is arranged opposite the wiring area 4 on the production roll 3 used to prepare the metal mesh touch sensor. When the roller body 1 rotates, it does not contact the wiring area 4.
