[0002] Nanoimprinting is a new pattern transfer device that is different from traditional photolithography technology.

[0052] Example:

[0053] See also Figure 1 to Figure 7 ,like Figure 1 As shown, the flexible film imprinting device in the preferred embodiment of the present invention includes a feeding mechanism 1, a glue dispensing mechanism 2, an imprinting mechanism 3 and a feeding mechanism 4 which are sequentially arranged along the production direction. The flexible film to be imprinted will pass through the feeding mechanism 1, the glue dispensing mechanism 2, the imprinting mechanism 3 and the feeding mechanism 4 in sequence to complete the overall imprinting process. In the preferred embodiment, a host computer is also provided, and the host computer is electrically connected to each component to control the overall operation process of the device.

[0054] Specifically, Figure 3 and Figure 4As shown, in the preferred embodiment, the loading mechanism 1 includes a unwinding member 101, and the flexible film is unwound by the unwinding member 101. In the specific implementation, the unwinding member 101 is a hand-expanding shaft, which is convenient for the flexible film to be stored and released. Similarly, the unloading mechanism 4 includes a winding member 401 and a third driving member 402. The third driving member 402 drives the winding member 401 to rotate, and the flexible film is wound by the winding member 401. In the specific implementation, the winding member 401 is a hand-expanding shaft, which is convenient for the flexible film to be stored and released. It can be understood that one end of the flexible film is connected to the unwinding member 101, and the other end is connected to the winding member 401. When the third driving member 402 drives the winding member 401 to rotate, the flexible film connected to the winding member 401 will also move, thereby driving the unwinding member 101 at the other end of the flexible film to rotate, thereby realizing unwinding. The third driving member 402 can use a motor to drive the winding member 401. The upper computer is electrically connected to the third driving member 402 to realize the upper computer's control over the third driving member 402. The driving force of the third driving member 402 can be adjusted according to actual conditions to control the rotation speed of the winding member 401 and thus control the moving speed of the flexible film.

[0055] Furthermore, if Figure 3 As shown, in the preferred embodiment, the feeding mechanism 1 also includes a first deviation correcting member 102 and a second detection member. The first deviation correcting member 102 is arranged between the unwinding member 101 and the dispensing mechanism 2, and the flexible film passes through the first deviation correcting member 102. The second detection member is electrically connected to the first deviation correcting member 102. The second detection member can detect the position of the flexible film in real time and feed back to the first deviation correcting member 102, and then the first deviation correcting member 102 performs real-time deviation correction. In specific implementation, the first deviation correcting member 102 can use a deviation corrector, and the second detection member uses an edge detection sensor, which can detect the current position of the flexible film in real time and feed back to the deviation corrector in real time for real-time deviation correction. The operator can preset a program in the first deviation correcting member 102 in advance, so that the flexible film passes according to a preset position during the process, to prevent the material from serpentine or uneven edges when entering the next process.

[0056] Optionally, a steering roller may be provided between the first deviation-correcting member 102 and the first glue-dispensing member 201 according to actual conditions, so that the flexible film can better perform subsequent work.

[0057] In addition, in the preferred embodiment, the feeding mechanism 1 also includes a first control member and a third detection member. The third detection member and the first control member are electrically connected to the host computer. The first control member is connected to the unwinding member 101. The third detection member detects the state of the flexible film and feeds it back to the host computer. The host computer can enable the first control member to control the tension of the unwinding member 101. In specific implementation, the third detection member can use a sensor to monitor the number of rotations of the unwinding member 101. The first control member can use a magnetic powder clutch, which cooperates with the unwinding member 101 using a hand expansion shaft to provide unwinding tension control. By setting the roll diameter, film thickness, magnetic powder force and combining the number of rotations of the unwinding member 101 detected by the third detection member, PID control is performed to maintain and ensure that the tension of the flexible film is always constant during continuous operation, so as to avoid changes in the shape of the flexible film due to changes in tension and subsequent printing errors.

[0058] Similarly, if Figure 4 As shown, in the preferred embodiment, the unloading mechanism 4 also includes a second deviation correcting member 403 and a fourth detection member. The second deviation correcting member 403 is arranged between the stamping mechanism 3 and the winding member 401, and the flexible film passes over the second deviation correcting member 403. The fourth detection member is electrically connected to the second deviation correcting member 403. The fourth detection member can detect the position of the flexible film in real time and feed back to the second deviation correcting member 403, and then perform real-time deviation correction through the second deviation correcting member 403. In specific implementation, the second deviation correcting member 403 can use a deviation corrector, and the second detection member uses an edge detection sensor, which can detect the current position of the flexible film in real time and feed back to the deviation corrector in real time for real-time deviation correction. The operator can preset a program in the second deviation correcting member 403 in advance, so that the flexible film passes according to a preset position during the process, to prevent the material from serpentine or uneven edges when winding.

[0059] Optionally, a steering roller may be provided between the second deviation-correcting member 403 and the stamping mechanism 3 according to actual conditions, so that the flexible film can better perform subsequent work.

[0060] In addition, in the preferred embodiment, the unloading mechanism 4 also includes a second control member and a fifth detection member. The fifth detection member and the second control member are electrically connected to the host computer. The second control member is connected to the winding member 401. The fifth detection member detects the state of the flexible film and feeds it back to the host computer. The host computer can enable the second control member to control the tension of the winding member 401. In specific implementation, the fifth detection member can use a sensor to monitor the number of rotations of the winding member 401. The second control member can use a magnetic powder clutch, which cooperates with the winding member 401 using a hand expansion shaft to provide material receiving tension control. By setting the roll diameter, film thickness, magnetic powder force and combining the number of rotations of the winding member 401 detected by the fifth detection member, PID control is performed to maintain and ensure that the tension of the flexible film is always constant during continuous operation, so as to avoid changes in the shape of the flexible film due to changes in tension and changes in the imprinted pattern during winding.

[0061] Furthermore, if Figure 5 and Figure 6 As shown, in the preferred embodiment, the stamping mechanism 3 includes a first stamping component 301 and a second stamping component 302. The first stamping component 301 includes a first driving member 3011 and a first stamping member 3012. The first driving member 3011 drives the first stamping member 3012 to move, and a first pattern is printed on the first stamping member 3012. The second stamping component 302 includes a second stamping member 3021 and a second driving member 3022. The second driving member 3022 drives the second stamping member 3021 to rotate. The second stamping member 3021 is arranged corresponding to the first stamping member 3012, and a second pattern is printed on the second stamping member 3021. The flexible film passes between the first stamping member 3012 and the second stamping member 3021. In this way, when the first stamping member 3012 and the second stamping member 3021 work at the same time, double-sided stamping of the flexible film can be achieved.

[0062] In a preferred embodiment, the first driving member 3011 and the second driving member 3022 are electrically connected to the host computer, and the operator can set it in advance in the host computer so that the driving of the first driving member 3011 and the second driving member 3022 is synchronized and stable. It can be understood that the first pattern printed on the first stamping member 3012 is the back pattern to be stamped on the flexible film, that is, the first stamping member 3012 can realize the back master function, and similarly, the second pattern on the second stamping member 3021 can be the front pattern to be stamped on the flexible film, and the second stamping member 3021 can realize the front master function. Marking points are set on the first stamping member 3012 and the second stamping member 3021 to facilitate the synchronization of the first stamping member 3012 and the second stamping member 3021 during operation.

[0063] In detail, Figure 2 and Figure 3 As shown, in the preferred embodiment, the dispensing mechanism 2 includes a first dispensing member 201 and a second dispensing member 202. The first dispensing member 201 is disposed between the feeding mechanism 1 and the stamping mechanism 3. The first dispensing member 201 can drop glue on a side of the flexible film facing the first dispensing member 201. The second dispensing member 202 is disposed between the first stamping member 3012 and the flexible film. The second dispensing member 202 can drop glue on a side of the first stamping member 3012 facing the second dispensing member 202.

[0064] It is understandable that since both sides of the flexible film need to be embossed, both sides also need to be coated with UV glue to facilitate subsequent embossing and curing. The first glue dispensing component 201 and the second glue dispensing component 202 can be electrically connected to the host computer, and the host computer controls the first glue dispensing component 201 and the second glue dispensing component 202 to automatically and according to the actual situation to drip glue. The UV glue dripped by the first glue dispensing component 201 can be dripped on the side of the flexible film facing it, that is, the front side of the flexible film, and the UV glue dripped by the second glue dispensing component 202 is dripped on the surface of the first embossing component 3012. When the subsequent flexible film passes by, the glue can be applied to the back of the flexible film, which is convenient for subsequent embossing. Optionally, the glue dispensing mechanism 2 can also be provided with a scraper and anilox roller according to the first glue dispensing component 201 and the second glue dispensing component 202, respectively. After the first glue dispensing component 201 and the second glue dispensing component 202 drip the UV glue onto the surface of the flexible film and the surface of the first embossing component 3012, the UV glue is evenly coated using the scraper and the anilox roller.

[0065] In addition, if Figure 7 As shown, in the preferred embodiment, the flexible film imprinting device further includes a curing mechanism 5, which includes a mounting member 501, a curing member 502 and an observation member 503. The curing member 502 and the observation member 503 are mounted on the mounting member 501, and the curing member 502 and the observation member 503 are located in the second imprinting member 3021. The curing member 502 can cure the glue on the flexible film. The observation member 503 is electrically connected to the host computer, and the observation member 503 can detect the real-time position of the first imprinting member 3012 and the second imprinting member 3021 and transmit the data to the host computer.

[0066] In specific implementation, the mounting member 501 can be a mounting frame with a certain height, so that it can pass through the middle of the second stamping member 3021 and place the curing member 502 and the observation member 503 therein. The curing member 502 can be a UV lamp, and the UV light emitted by it passes through the second stamping member 3021 and the transparent flexible film to simultaneously cure the micro-patterns embossed on the UV glue on both sides of the flexible film. The observation member 503 can be a visual camera, two of which are provided, and a 45-degree angle reflector is used to realize the optical path turning, realize the real-time position display, and can detect the marking points in the second stamping member 3021 and the marking points on the pattern of the first stamping member 3012, and provide real-time feedback on the current position deviation of the two marking points. The observation member 503 can well observe and photograph the position deviation between the marking points on the first stamping member 3012 and the second stamping member 3021, and transmit it to the host computer, and then the host computer controls the first stamping member 3012 and the second stamping member 3021 to make them run in unison.

[0068] In specific implementation, the first stamping member 3012 may be a steel belt, and the first pattern may be attached to the steel belt. During operation, the steel belt reciprocates to realize the cyclic reciprocating operation of the pattern.

The control component 3015 can use a servo motor with a screw module, and adopt a torque mode during operation to ensure that the force on both sides is uniform, thereby controlling the error of the steel strip.

[0070] Preferably, in the preferred embodiment, positioning members are provided on the active member 3013 and the driven member 3014, and the first stamping member 3012 is provided with a positioning hole 30121 corresponding to the positioning member, and the positioning member can pass through the positioning hole 30121 and position the first stamping member 3012. In specific implementation, the positioning member can be a positioning pin, which can mesh with the positioning hole 30121, and the matching of the two is equivalent to the meshing between gears, which can control the running accuracy of the first stamping member 3012 and eliminate the slippage between the steel belt and the wheel.

[0071] Since the first stamping member 3012 is made of a steel belt, one side of the circulating steel belt is longer and is prone to collapse due to gravity. One or more support rollers can be placed under the collapsed steel belt to support the steel belt, ensuring better and more reliable stamping.

[0072] In addition, in the preferred embodiment, the active member 3013 and the driven member 3014 are both connected to the first detection member 3016, and the first detection member 3016 is electrically connected to the host computer. The first detection member 3016 can detect the running position of the first stamping member 3012 and transmit the data to the host computer. It is understandable that the first detection member 3016 can use an external encoder, which is connected to the active member 3013 and the driven member 3014 by friction, and can monitor the running position of the steel belt in real time and feedback to the host computer, and then the operation of the first stamping member 3012 is regulated by the host computer.

[0073] In more detail, Figure 6 As shown, in the preferred embodiment, the second stamping component 302 further includes an adjustment platform 3023, the second stamping component 3021 is connected to the adjustment platform 3023, the adjustment platform 3023 is connected with a fourth driving member and a fifth driving member, the fourth driving member and the fifth driving member are electrically connected to the host computer, the fourth driving member drives the adjustment platform 3023 to move along the first direction a, and the fifth driving member drives the adjustment platform 3023 to move along the second direction b. Among them, the first direction a is a direction parallel to the production direction, the second direction b is perpendicular to the first direction a, and the second direction b is parallel to the plane where the adjustment platform 3023 is located.

[0074] It is understandable that a base can also be provided so that the fourth drive member and the fifth drive member are placed on the base, so that the fourth drive member and the fifth drive member can work. The base can adopt a UVW platform, which can be docked with a visual CCD correction system to achieve high-precision correction. During specific implementation, the fourth drive member and the fifth drive member can both use motors, the fourth drive member can be provided with two, the fifth drive member can be provided with one, or the fourth drive member can be provided with one, and the fifth drive member can be provided with two, so that the adjustment platform 3023 can be realized with the plane where the first direction a and the second direction b are located as the reference plane, and rotates around any point as the center. At the same time, the observation member 503 in the curing mechanism 5 can transmit the detected result to the host computer, and the host computer can control the fourth drive member and the fifth drive member according to the result to adjust the adjustment platform 3023, so as to ensure that the imprinting process is highly accurate and reliable.

[0075] Since the second stamping member 3021 stamps the upper surface of the flexible film, and the second stamping member 3021 needs to stamp the lower surface of the flexible film, a mounting hole can be opened on the adjustment platform 3023 to allow the first stamping component 301 to pass through, and the first stamping member 3012 is correspondingly arranged directly below the second stamping member 3021. When the second stamping component 302 needs to be adjusted, the adjustment platform 3023 can be adjusted to move around the first stamping component 301, thereby making the structure more compact and achieving a better double-sided stamping effect.

[0076] In specific implementation, the second driving member 3022 provides power for the second stamping member 3021, and can be controlled by a position loop electronic cam. At the same time, since the second driving member 3022 and some components in the first stamping assembly 301 are electrically connected to the host computer, the host computer can dynamically modify the electronic gear ratio of the second driving member 3022 according to the signal of the running position of the first stamping member 3012, and perform position compensation in real time to ensure that the first stamping member 3012 and the second stamping member 3021 are synchronized, and the patterns stamped on both sides of the flexible film correspond. The second stamping member 3021 can be a quartz roller, which is a transparent roller, and the second pattern printed on it is also a transparent master. During operation, the second pattern on the roller can be operated through the operation of the quartz roller to achieve a cyclic reciprocating operation.

[0077] Preferably, in the preferred embodiment, the second stamping component 302 further includes a limiting component 3024, the limiting component 3024 includes a limiting member 30241 and a moving component 30242, the limiting member 30241 abuts against the second stamping component 3021, the moving component 30242 is electrically connected to the host computer, the moving component 30242 is connected to the limiting member 30241, and the host computer can control the moving component 30242 to drive the limiting member 30241 to move along the third direction c. The third direction c is perpendicular to the plane where the first direction a and the second direction b are located.

[0078] It is understandable that the moving assembly 30242 may include a cylinder, a linear rail and a connector. The moving assembly 30242 may use a cylinder in conjunction with a linear rail to drive the connector to move along the linear rail. The limiter 30241 is connected to the connector, so that the cylinder drives the connector to drive the limiter 30241 to move. The limiter 30241 may use a grabbing clamp, and one may be provided on both sides of the top and both ends of the second stamping member 3021 to control the position of the second stamping member 3021 in the third direction c, i.e., the height direction. The radial force of the bearing on the limiter 30241 presses down the second stamping member 3021, and rotates synchronously with the second stamping member 3021. The axial force of the bearing on the limiter 30241 controls the side end of the expansion sleeve on the second stamping member 3021 to limit the movement of the second stamping member 3021 in the front and rear directions. Optionally, a plurality of position-limiting members 30241 and movable components 30242 may be correspondingly disposed at the bottom of the second stamping member 3021 , so as to coordinate with adjusting the position of the second stamping member 3021 and also perform further position limiting.

[0079] More preferably, in the preferred embodiment, the second stamping component 302 also includes a support component 3025, the support component 3025 is connected to the adjustment platform 3023, the support component 3025 includes a first support member 30251, a second support member 30252 and a third support member 30253, the first support member 30251 supports the flexible film, the second support member 30252 supports the first stamping member 3012, and the third support member 30253 supports the second stamping member 3021.

[0080] It is understandable that the first support member 30251, the second support member 30252 and the third support member 30253 can all be rollers, and two rollers can be provided for each, located on both sides of the components to be supported. Since the first stamping member 3012 needs to be placed below the second stamping member 3021, the first stamping assembly 301 can be installed below the second stamping member 3021 through the mounting hole provided on the adjustment platform 3023, so the first stamping member 3012 is located between the second stamping member 3021 and the adjustment platform 3023, and the flexible film needs to be between the first stamping member 3012 and the second stamping member 3021. Therefore, the first support member 30251 is correspondingly arranged to be located below the flexible film during operation and can support the flexible film, the second support member 30252 is located below the first stamping member 3012 during operation and can support the first stamping member 3012, and the third support member 30253 can support the second stamping member 3021. At the same time, the first support member 30251 can also control the running direction of the flexible film, ensuring that the moving direction of the flexible film is along the first support member 30251, so as to achieve the feeding and pressing of the flexible film and the discharging and demolding of the flexible film, and the second support member 30252 can control the running direction of the first stamping member 3012, so that the first stamping member 3012 runs along the direction of the second support member 30252, so as to achieve high-precision operation of the first stamping member 3012. The third support member 30253 can also control the position of the second stamping member 3021, and provide support for the second stamping member 3021.

[0081] The flexible film embossing device in the present invention can realize double-sided synchronous embossing, and the front master and the back master are operated synchronously to overprint the front pattern and the back pattern onto the intermediate film. With the back master and the first embossing member as the reference, the registration accuracy is controlled by controlling the offset of the front master, i.e., the second embossing member. At the same time, an observation member is set to monitor the angle deviation value of the first embossing member and the second embossing member, and the corresponding deviation value is transmitted to the adjustment platform, and the adjustment platform compensates for the deviation value accordingly. In addition, the setting of the first support member limits the feeding path of the flexible film and provides a demoulding angle for demoulding. And by adjusting the position, the back demoulding is completed first, and then the front demoulding is completed during the demoulding process. At the same time, the tension of the flexible film loading and unloading is controllable to ensure that the flexible film does not deform during operation.

[0082] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
