Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor equipment, in particular to a roller pressing device which is convenient for stamping and demoulding. Background Art

[0002] Imprint lithography is a surface pattern replication technique that involves transferring a pattern from a template or stamp to a substrate by contacting the structured surface of the template or stamp with a moldable layer coated on the substrate surface. The moldable layer is usually provided as a nanoimprint glue, which is hardened or cured after the pattern transfer, and once the template or stamp is removed from the substrate, an inverse replica is formed on the surface of the substrate. Imprint technology has been proven to be one of the most effective techniques for replicating nanostructures, and the technology is also often referred to as nanoimprint lithography (NIL).

[0003] Under the existing technology, the process of transferring the above-mentioned pattern from the template or stamp to the substrate is usually carried out by rolling the mold sheet with a pressure roller. However, due to the unreasonable structural design of the rolling device, this method can easily cause incomplete pattern transfer when the mold sheet is rolled or the mold sheet is separated from the substrate, thereby affecting the pattern transfer quality of the entire mold sheet.

[0004] Therefore, those skilled in the art are committed to developing a roller pressing device that is convenient for embossing and demoulding and can improve the quality of pattern transfer. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the utility model discloses a roller pressing device which is convenient for embossing and demoulding. The technical problem to be solved is to provide a roller pressing device which is convenient for embossing and demoulding and can improve the quality of pattern transfer.

[0006] To achieve the above-mentioned purpose, the utility model provides a rolling device for convenient embossing and demolding, comprising a shell and a roller assembly, wherein the lower bottom surface of the shell is provided with an opening, and the opening is rectangular; the roller assembly is arranged in the shell and is used for installing and rolling the mold piece, the roller assembly comprises a main roller floatingly arranged above the opening, and auxiliary rollers arranged on opposite sides of the main roller and tangentially arranged to the main roller, namely a first roller assembly and a second roller assembly; the first roller assembly and the second roller assembly are both located above the axis of the main roller and can be adjusted vertically and horizontally, the mold piece is wound between the first roller assembly or the second roller assembly and the main roller, one end of the mold piece tangent to the lower bottom surface of the main roller extends outwardly below the shell and is connected to an external first component, and the other end of the mold piece passes through the first roller assembly or the second roller assembly and extends outwardly to one side of the shell and is connected to an external second component.

[0007] Preferably, the first pressure roller assembly includes a first auxiliary roller and a second auxiliary roller arranged in pairs, and the first auxiliary roller and the second auxiliary roller are arranged tangentially up and down; the second pressure roller assembly includes a third auxiliary roller and a fourth auxiliary roller arranged in pairs, and the third auxiliary roller and the fourth auxiliary roller are arranged tangentially up and down. The die sheet forms an upward warping shape by passing between the first auxiliary roller and the second auxiliary roller or between the third auxiliary roller and the fourth auxiliary roller. In addition, in this scheme, the auxiliary rollers arranged in pairs on both sides of the main roller can be adjusted by the auxiliary roller adjustment mechanism, that is, the position of the auxiliary rollers arranged in pairs along the up and down direction of the shell, or the left and right direction, so as to change the height of the main roller exposed to the bottom surface of the shell, which plays a role in adjusting the pressure of the main roller. The auxiliary roller adjustment mechanism can be implemented by a screw rod or a slide rail. The specific mechanism setting of this part is disclosed in the relevant documents and will not be described in detail here.

[0008] Preferably, the first auxiliary roller is located below the second auxiliary roller, and the third auxiliary roller is located below the fourth auxiliary roller. The roller surfaces of the first auxiliary roller and the third auxiliary roller are both circumferentially provided with concave surfaces for avoiding the transfer side pattern of the mold sheet.

[0009] Preferably, the width of the concave surface is smaller than the length of the first auxiliary roller and the third auxiliary roller.

[0010] Since the pattern structure of the mold piece is arranged downward, in order to avoid the damage to the pattern structure caused by the auxiliary rollers arranged in pairs on one side when rolling the mold piece, the utility model arranges a concave surface with an avoidance function on the circumferential surface of the auxiliary roller surface meshed with the main roller, so that the two auxiliary rollers only roll the edge of the mold piece, and the part of the mold piece with the pattern structure in the middle is avoided by the concave surface. Since the deformation stress of the main roller is mostly concentrated at the two ends of the main roller, the auxiliary roller arranged in this way reduces the meshing area between the auxiliary roller and the main roller, and the roller surface cannot be completely meshed with the roller surface of the main roller, but the meshing of the two ends of the auxiliary roller with the two ends of the main roller can still increase the rolling force of the main roller and prevent the deformation of the main roller.

[0011] Preferably, the first external component and the second external component are both configured as a mold tensioning mechanism and / or a mold winding mechanism.

[0012] Preferably, a displacement platform for carrying the substrate is provided below the main roller; both ends of the mold are tensioned by the mold tensioning mechanism respectively, and the shell moves along the pressing or demolding direction of the mold and the substrate under the action of an external driving force.

[0013] Preferably, the two ends of the mold are respectively matched with the mold winding mechanism. When the position of the shell is fixed, the mold is pulled by the mold winding mechanism to move along the pressing or demolding direction of the mold and the substrate, and the substrate moves synchronously with the mold under the action of the displacement table.

[0014] In the above scheme, since paired auxiliary rollers are respectively arranged on both sides of the main roller, the rolling direction of the mold sheet can be conveniently adjusted according to the process requirements, that is, the paired auxiliary rollers on the left side can be used to make the main roller roll the mold sheet to the left, or the paired auxiliary rollers on the right side can be used to make the main roller roll the mold sheet to the right.

[0015] Furthermore, the rolling device in this scheme can be set to two working modes, active and passive. When set to the passive working mode, the shell can be fixed, and only the displacement stage, substrate and mold can be moved synchronously. The specific application scheme can roll and demould the substrate and mold set in a roll by a pair of rollers. The operation is the same as the above method, except that the two ends of the substrate and the mold are positioned by the rollers. After the first stage of pattern transfer is completed, the rollers are used to pull the mold and the substrate forward to the preset position at the same time, and then the rollers stop rotating, and then the second stage of pattern transfer is completed. And so on, the pattern transfer of the mold is completed efficiently and quickly.

[0016] Preferably, when the active working mode is adopted, only the housing can be driven to move, so that the displacement stage, substrate and mold are fixed during stamping or demolding. Specifically, a driving mechanism for driving the main roller to rotate can be arranged between the first pressing roller assembly and the second pressing roller assembly.

[0017] Preferably, the driving mechanism includes a motor arranged in the housing, a driving wheel arranged at the driving end of the motor, a driven wheel fastened to the main roller end shaft, a tensioning wheel group arranged between the driving wheel and the driven wheel, and a synchronous belt cooperating with the driving wheel, the driven wheel and the tensioning wheel group.

[0018] Preferably, the tensioning wheel assembly includes a guide rail horizontally arranged in the housing, a first tensioning wheel and a second tensioning wheel synchronously arranged to slide toward or away from each other along the guide rail, and an adjustment component for adjusting the distance between the first tensioning wheel and the second tensioning wheel. The adjustment component can be arranged by arranging a slide groove on the housing, slidingly installing the axles of the first tensioning wheel and the second tensioning wheel in the slide groove, and arranging a nut on the axle to lock the axle.

[0019] In the above scheme, a driving wheel, a tensioning wheel and a synchronous belt are arranged above the main roller to drive the main roller to rotate. In order to match the up and down floating of the main roller, the distance between the two tensioning wheels can be adjusted, so that the synchronous belt is always in a tensioned state when the main roller is working. In actual use, the mold piece can be installed first, and then the position of the auxiliary rollers arranged in pairs on both sides of the main roller can be adjusted, and then the distance between the two tensioning wheels can be adjusted according to the position of the main roller. After the synchronous belt is tensioned, the driving wheel is started to rotate. At this time, the entire rolling device can roll the mold piece along the preset direction, and then the mold piece after the stamping can be demolded by flipping the driving wheel.

[0020] The beneficial effects of the utility model are:

[0021] The auxiliary rollers, i.e., the first pressing roller assembly and the second pressing roller assembly, which are arranged in pairs on both sides of the main roller, can not only adjust the height of the main roller exposed from the bottom surface of the shell, but also provide better auxiliary support when the main roller rotates, thereby preventing the main roller from deforming during the rolling process. More importantly, since the rolling surface of the main roller is located below the first pressing roller assembly and the second pressing roller assembly, one end of the mold sheet wound by the main roller and the auxiliary roller is always kept in an upward warping state. Therefore, when the two ends of the mold sheet are in a fastened state, the entire rolling device can be driven by external force to move along the length direction of the mold sheet, and when the main roller moves toward the warped end of the mold sheet to roll the mold sheet, bubbles will not be generated between the mold sheet and the substrate below, thereby achieving the purpose of eliminating bubbles. When the mold and the substrate are pressed together and the embossed pattern is cured by a UV light curing lamp arranged in the shell, the entire rolling device can move in the opposite direction, that is, the rolling device can be reset. At this time, during the resetting process, since one end of the above-mentioned mold always remains warped upward, the gap between the warped part of the mold and the underlying substrate can be used to conveniently lift and remove the mold from above the substrate, thereby realizing demolding of the mold and the substrate. Moreover, this demolding method can minimize the tearing and damage of the underlying pattern during the demolding process, thereby effectively improving the pattern transfer quality.

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific manner, and therefore cannot be understood as a limitation on the present invention. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] like Figure 1 As shown, the utility model provides a rolling device for convenient stamping and demoulding, comprising a shell 1 and a roller assembly 2, wherein the lower bottom surface of the shell 1 is provided with an opening, and the opening is rectangular; the roller assembly 2 is arranged in the shell 1 and is used for the installation and rolling of the mold 3, the roller assembly 2 comprises a main roller 23 floatingly arranged above the opening, and auxiliary rollers arranged on opposite sides of the main roller 23 and tangentially arranged with the main roller 23, namely, a first roller assembly 21 and a second roller assembly 22; the first roller assembly 21 and the second roller assembly 22 are both located above the axis of the main roller 23 and can be adjusted vertically and horizontally, a mold 3 is wound between the first roller assembly 21 or the second roller assembly 22 and the main roller 23, one end of the mold 3 tangentially to the lower bottom surface of the main roller 23 extends outwardly below the shell 1 and is connected to an external first component 41, and the other end of the mold 3 passes through the first roller assembly 21 or the second roller assembly 22 and extends outwardly to one side of the shell 1 and is connected to an external second component 42.

[0031] Specifically, the first external member 41 and the second external member 42 are both configured as a mold tensioning mechanism and / or a mold winding mechanism. A displacement table 5 for carrying the substrate is provided below the main roller 23; both ends of the mold 3 are tensioned by the mold 3 tensioning mechanism respectively, and the housing 1 moves along the pressing or demolding direction of the mold 3 and the substrate under the action of an external driving force.

[0032] The two ends of the mold sheet 3 are respectively matched with the mold sheet 3 winding mechanism. When the housing 1 is fixed, the mold sheet 3 is pulled by the mold sheet 3 winding mechanism to move along the pressing or demoulding direction of the mold sheet 3 and the substrate, and the substrate is synchronously moved with the mold sheet 3 by the displacement stage 5. Since both sides of the main roller 23 are respectively provided with paired auxiliary rollers, the rolling direction of the mold sheet 3 can be conveniently adjusted according to the process requirements, that is, the auxiliary rollers arranged in pairs on the left side can be used to make the main roller 23 roll the mold sheet 3 to the left, or the auxiliary rollers arranged in pairs on the right side can be used to make the main roller 23 roll the mold sheet 3 to the right.

[0033] The above is the first embodiment of the utility model. The auxiliary rollers, namely the first pressing roller assembly 21 and the second pressing roller assembly 22, which are arranged in pairs on both sides of the main roller 23, can not only adjust the height of the main roller 23 exposed from the bottom surface of the shell 1, but also provide better auxiliary support for the main roller 23 when it rotates, so as to avoid the deformation of the main roller 23 during the rolling process. More importantly, since the rolling surface of the main roller 23 is located below the first pressing roller assembly 21 and the second pressing roller assembly 22, one end of the mold sheet 3 wound by the main roller 23 and the auxiliary roller is always kept in an upward warping state. Therefore, when the two ends of the mold sheet 3 are in a fastened state, the entire rolling device can be driven by external force to move along the length direction of the mold sheet 3, and when the main roller 23 moves to the warped end of the mold sheet 3 to roll the mold sheet 3, bubbles will not be generated between the mold sheet 3 and the substrate below, thereby achieving the purpose of eliminating bubbles. When the mold 3 is pressed together with the substrate and the embossed pattern is cured by the UV light curing lamp arranged in the shell 1, the entire rolling device can move in the opposite direction, that is, the rolling device can be reset. At this time, during the resetting process, since one end of the above-mentioned mold 3 always remains warped upward, the gap between the warped part of the mold 3 and the underlying substrate can be used to conveniently lift and remove the mold 3 from above the substrate, thereby realizing the demoulding of the mold 3 and the substrate. In addition, this demoulding method can minimize the tearing and damage of the underlying pattern during the demoulding process, thereby effectively improving the pattern transfer quality.

[0034] Further, the first pressing roller assembly 21 includes a first auxiliary roller 211 and a second auxiliary roller 212 arranged in pairs, and the first auxiliary roller 211 and the second auxiliary roller 212 are arranged tangentially up and down; the second pressing roller assembly 22 includes a third auxiliary roller 223 and a fourth auxiliary roller 224 arranged in pairs, and the third auxiliary roller 223 and the fourth auxiliary roller 224 are arranged tangentially up and down. The mold 3 is formed into an upward warping shape by passing between the first auxiliary roller 211 and the second auxiliary roller 212 or between the third auxiliary roller 223 and the fourth auxiliary roller 224. In addition, in this scheme, the auxiliary rollers arranged in pairs on both sides of the main roller 23 can be adjusted by the auxiliary roller adjustment mechanism, that is, the position of the auxiliary rollers arranged in pairs along the up and down direction of the shell 1, or the left and right direction, is changed, so as to change the height of the main roller 23 exposed to the bottom surface of the shell 1, and play a role in adjusting the pressure of the main roller 23. The auxiliary roller adjustment mechanism can be implemented by a screw rod or a slide rail. The specific mechanism setting of this part is disclosed in the relevant documents and will not be described in detail here.

[0035] Furthermore, the first auxiliary roller 211 is located below the second auxiliary roller 212, and the third auxiliary roller 223 is located below the fourth auxiliary roller 224. The roller surfaces of the first auxiliary roller 211 and the third auxiliary roller 223 are both circumferentially provided with a concave surface 2111 for avoiding the transfer side pattern of the mold 3, and the width of the concave surface 2111 is smaller than the length of the first auxiliary roller 211 and the third auxiliary roller 223.

[0036] Since the pattern structure of the mold sheet 3 is arranged downward, in order to avoid the damage to the pattern structure when the secondary rollers arranged in pairs on one side roll the mold sheet 3, the utility model arranges a concave surface 2111 with an avoidance function on the circumferential surface of the secondary roller surface meshed with the main roller 23, so that the two secondary rollers only roll the edge of the mold sheet 3, and the portion of the mold sheet 3 with the pattern structure arranged in the middle is avoided by the concave surface 2111. Since the deformation stress of the main roller 23 is mostly concentrated at the two ends of the main roller 23, the secondary roller arranged in this way reduces the meshing area between the secondary roller and the main roller 23, and the roller surface cannot be completely meshed with the roller surface of the main roller 23, but the meshing of the two ends of the secondary roller with the two ends of the main roller 23 can still increase the rolling force of the main roller 23 and prevent the deformation of the main roller 23.

[0037] The utility model can also have a variety of implementation modes. Specifically, the rolling device in this solution can be set to two working modes: active and passive.

[0038] like Figure 5As shown, it is the second embodiment of the utility model. When set to the passive working mode, the housing 1 can be fixed, and only the displacement stage 5, the substrate and the mold 3 can be moved synchronously. The specific application scheme can roll and demould the rolled substrate and the mold 3 by the paired rollers 43. The operation is the same as the above method, except that the two ends of the substrate and the mold 3 are positioned by the paired rollers 43. After the first stage of pattern transfer is completed, the paired rollers 43 are used to pull the mold 3 and the substrate forward to the preset position at the same time, and then the paired rollers 43 stop rotating, and then the second stage of pattern transfer is completed. And so on, the pattern transfer of the mold 3 is completed efficiently and quickly.

[0039] like Figure 6 As shown, it is the third embodiment of the utility model. When the active working mode is adopted, only the housing 1 can be driven to move, so that the displacement stage 5, the substrate and the mold 3 are fixed during stamping or demolding. Specifically, a driving mechanism 6 for driving the main roller 23 to rotate can be arranged between the first pressing roller assembly 21 and the second pressing roller assembly 22. The driving mechanism 6 includes a motor arranged in the housing 1, a driving wheel 61 arranged at the driving end of the motor, a driven wheel 62 fastened to the end shaft of the main roller 23, a tensioning wheel group 63 arranged between the driving wheel 61 and the driven wheel 62, and a synchronous belt 64 matched with the driving wheel 61, the driven wheel 62 and the tensioning wheel group 63. In addition, the tensioning wheel group 63 includes a guide rail horizontally arranged in the housing 1, a first tensioning wheel and a second tensioning wheel synchronously arranged to slide toward or away from each other along the guide rail, and an adjustment component for adjusting the distance between the first tensioning wheel and the second tensioning wheel. The adjustment component can be arranged in a manner of arranging a slide groove on the housing 1, slidingly installing the axles of the first tensioning wheel and the second tensioning wheel in the slide groove, and arranging nuts on the axles that can lock the axles.

[0040] In the above embodiment, the main roller 23 is driven to rotate by arranging a driving wheel, a tensioning wheel and a synchronous belt 64 above the main roller 23. In order to match the up and down floating of the main roller 23, the spacing between the two tensioning wheels can be adjusted, so that the synchronous belt 64 is always in a tensioned state when the main roller 23 is working. In actual use, the mold 3 can be installed first, and then the position of the auxiliary rollers arranged in pairs on both sides of the main roller 23 can be adjusted, and then the spacing between the two tensioning wheels can be adjusted according to the position of the main roller 23. After the synchronous belt 64 is tensioned, the driving wheel is started to rotate. At this time, the entire rolling device can roll the mold 3 along the preset direction, and then the mold 3 after the stamping can be demolded by turning the driving wheel.

[0041] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
