Description

Technical Field

[0001] The utility model relates to a roller device, in particular to a roller device used for preventing photoresist from falling off. Background Art

[0002] In the preparation process of Metal Mesh flexible touch sensor, it is necessary to go through processes such as photoresist coating, baking, exposure, development, etching, degumming, and blackening. In these automated roll-to-roll processes, the Metal Mesh film often comes into contact with the rollers in the automated equipment. Under a certain tension and speed, the transmission of the rollers will drive the Metal Mesh film forward until the process is completed and the Metal Mesh film is reeled up.

[0003] The copper coating on the surface of the Metal Mesh film has good adhesion to the substrate. During the friction between the roller and the Metal Mesh film, the copper coating is not easy to fall off. The photoresist is coated on the surface of the copper coating and combined with the surface of the copper coating after baking. At this time, the adhesion between the photoresist and the copper coating is relatively poor. During the friction between the roller and the Metal Mesh film or the friction between the layers of the Metal Mesh film coil, the photoresist with a larger area is not easy to fall off because the photoresist itself has a strong cohesive force; the photoresist with a smaller area, especially the photoresist in the edge routing area of ​​the Metal Mesh, has a line width and line spacing between 6um / 6um and 15um / 15um, which is easy to separate from the edge routing of the Metal Mesh, causing the photoresist on the edge routing surface of the Metal Mesh to fall off, and the copper coating in the area where the photoresist falls off will be exposed. After the etching process, the copper circuit in this area will be etched away, resulting in the disconnection of the copper circuit and the failure of the Metal Mesh function. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] The utility model provides a roller device for preventing photoresist from falling off, so as to solve the problem in the prior art that the Metal Mesh film often contacts with the roller in the automation equipment during the process of receiving and transmitting the material, and the photoresist falls off during the contact with the roller, causing the Metal Mesh function to fail.

[0027] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 to Figure 2 A roller device for preventing photoresist from falling off in an embodiment of the present application comprises a feed roller area 1, a transmission roller area 2 and a receiving roller area 3 which are aligned in sequence; the transmission roller area 2 comprises a developing roller area 20, a washing roller area 21 and a drying roller area 22; the developing roller area 20, the washing roller area 21 and the drying roller area 22 are all composed of a plurality of aligned transmission rollers 200; grooves 201 are provided on both sides of the transmission roller 200, and the position of the grooves 201 corresponds to the edge routing area of ​​the Metal Mesh film, and the width of the grooves 201 is not less than the maximum width of the edge routing area of ​​the Metal Mesh film.

[0028] In the roller device for preventing photoresist from falling off of the utility model, the width of the groove 201 includes but is not limited to 0.2 cm to 1 cm, and the groove width is adjusted according to the maximum width of the edge routing area of ​​the Metal Mesh film to ensure that the width of the groove 201 is not less than the maximum width of the edge routing area of ​​the Metal Mesh film, so that when the Metal Mesh film passes through a certain transmission roller 200, the edge routing area of ​​the Metal Mesh film is all located above the groove 201 and placed in the center, and will not be offset, so as to ensure that during the transmission process of the transmission roller 200, the edge routing area of ​​the Metal Mesh film will not directly contact the transmission roller 200, but is arranged above the groove 201 in the air, thereby avoiding the edge routing of the Metal Mesh film and the transmission roller 200 from rubbing against each other, and preventing the photoresist on the surface of the copper plating layer from falling off.

[0029] In addition, the depth of the groove 201 includes but is not limited to 0.1 mm to 1 mm, and the depth is adjusted according to the diameter of the transmission roller 200 and the processing method.

[0030] The feed roller area 1 is composed of a large feed roller 10 and a plurality of small feed rollers 11, all of which are made of stainless steel SUS304 and are solid cylinders. The diameter of the large feed roller 10 is 10 cm to 15 cm, and the diameter of the small feed roller 11 is 3 to 5 cm. The number of rollers is set according to the reserved space, including but not limited to 10 to 15. When the Metal Mesh film coil passes through the feed roller area 1, since there is a protective film on the front and back of the Metal Mesh film coil, the photoresist on the surface of the Metal Mesh copper plating layer can be effectively protected, so the Metal Mesh film coil can be directly transmitted through the feed roller area 1.

[0031] Furthermore, the driving rollers in the developing roller area 20 and the washing roller area 21 are made of rubber, and the driving roller 200 in the drying roller area 22 is made of a metal roller with Teflon on the surface, and is in the shape of a solid cylinder, with a roller diameter of 3 cm to 5 cm, and the number of rollers is set according to the reserved space, including but not limited to 100 to 150. The driving roller 200 in the drying roller area is made of metal and Teflon to increase heat resistance and extend service life.

[0032] Furthermore, the material receiving roller area 3 is composed of a large winding roller and multiple small rollers, all of which are made of stainless steel SUS304 and are solid cylindrical in shape. The diameter of the large roller is 10cm~15cm, and the diameter of the small roller is 3~5cm. The number of stainless steel rollers is set according to the reserved space, including but not limited to 10~15.

[0033] based on Figures 3 to 6 As a further preferred embodiment of the present application, the front and back sides of the Metal Mesh film will be coated during the winding process. Due to the existence of the coating tension, the protective film and the photoresist will rub against each other during the coating process. The large winding roller squeezes the protective film and then squeezes the photoresist. The photoresist is at risk of falling off due to the squeezing and friction, so a roll spacing component 4 is added below the end of the receiving roller area 3.

[0034] The coil spacing component 4 is arranged at the end of the track of the receiving roller area 3. The coil spacing component 4 is used to transmit two oppositely arranged embossed narrow belts 45. The two embossed narrow belts 45 are arranged on the left and right sides below the end of the receiving roller area 3. Relative to the installation space position, they are just coated on the invalid area on both sides of the Metal Mesh film, 1 to 2 cm away from the edge, and can be installed and unloaded at any time.

[0035] Specifically, the coil spacing assembly 4 in this embodiment includes a mounting bracket 40, a reel 41, a coiling tray 42 and a baffle 43; two mounting brackets 40 are arranged on both sides below the end of the receiving roller area 3; the reel 41 is rotatably arranged on the mounting bracket 40 by a driving motor 44, and the reel size includes but is not limited to a cylindrical reel length of 173mm and a reel diameter of 3 inches. The reel 41 is provided with a coiling tray 42 that follows the reel 41, and the reeling tray 42 is used to carry an embossed narrow tape 45. The embossed narrow tape 45 is a layer of PET film with countless uniformly arranged convex points on the surface, with a thickness of 25um, a width of 10mm, and a length determined according to the length of the Metal Mesh film coil, including but not limited to 420m. The two baffles 43 are arranged on the reel 41 and are located on both sides of the coil reel 42. The height and thickness of the baffles 43 are not limited. The baffles 43 can prevent the embossed narrow tape 45 from shaking left and right during the lamination process, thereby avoiding the displacement of the embossed narrow tape 45 during lamination. At the same time, the embossed narrow tapes 45 on the two coil reels are respectively located in the invalid areas on both sides of the Metal Mesh film, so that the Metal Mesh film will not be damaged during winding.

[0036] Furthermore, the convex point may be circular or square, or other shapes, which can be adjusted according to actual needs.

[0037] During operation, when the large roller in the receiving roller area 3 reels the Metal Mesh film, the embossed narrow bands 45 installed on the left and right sides below the receiving roller area 3 start to work synchronously. The driving motor 44 drives the reel 41 to rotate, and the reel 41 drives the embossed narrow bands 45 on the reel disk 42 to be transmitted forward to the invalid areas on both sides of the surface of the Metal Mesh photoresist, so that the two embossed narrow bands 45 are coated on the photoresist surface of the Metal Mesh film together when the Metal Mesh film is reeled, and are reeled between the layers of the Metal Mesh coil at the same time. The convex points of the embossed narrow bands 45 will separate the layers of the Metal Mesh coil, prevent the layers of the Metal Mesh coil from rubbing against each other, and avoid the photoresist from falling off, which is highly practical.

[0038] In summary, the roller device provides a groove 201 on the transmission roller 200 and adds a coil spacing component 4 so that the photoresist of the Metal Mesh film will not fall off when the coil is transmitted, thereby ensuring the effectiveness and completeness of the Metal Mesh film function and good practicality.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
