Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser holographic anti-counterfeiting technology, in particular to a high-adhesion deep-line lens transfer card paper production equipment and its production process. BACKGROUND

[0002] As a comprehensive anti-counterfeiting means combining new type of plate making process, computer lithography, precision electroforming, laser holographic molding and fine chemical industry, laser holographic anti-counterfeiting technology is widely used in the field of anti-counterfeiting, in which laser holographic molding is the core link, and UV molding machine is particularly suitable for copying deep-line (such as cat eye, micro lens) holographic image because of 100% solid content of UV coating and 6-7 times of coating thickness of solvent type coating, and becomes the key equipment for deep-line lens transfer card paper production.

[0003] The master plate engraving of deep-line holographic image adopts maskless laser direct writing lithography holographic image technology, considering the generality, cost, yield and limitation of lithography technology of deep-line holographic image, the size of deep-line holographic image is generally within 20cm*20cmn. Deep-line holographic pattern is not generally applied alone, and is usually applied by UV plate assembling holographic nickel plate method to assemble deep-line holographic image on background holographic nickel plate with much larger area than itself.

[0004] The process of UV splicing holographic nickel plate is as follows: firstly, a large plate with background pattern information and multiple small plates with unit pattern information (deep groove (such as cat eye, microlens) holographic image) need to be made, and finally the unit pattern information on the surface of all small plates is transferred to the large plate with background pattern information to realize splicing operation. Since the deep groove lens holographic image is made after the UV light curing paint is coated on the background information, compounded with the deep groove lens holographic image, light cured and peeled off, therefore, the image feature depth (such as 7um) of the deep groove lens holographic image is higher than the feature depth (such as 2um) of the background holographic image. Similarly, in order to accurately compare the deep groove lens pattern with the background pattern information (including customer files), it is necessary to set the front pull specified position (sleeved position) needle position line (2 groups of multiple short lines regularly set, perpendicular to the right side tracking line), the right pull specified position (sleeved position) needle position line (2 groups of multiple short lines regularly set, parallel to the right side tracking line) and the right side tracking line (the tracking line is a holographic plain image with a thickness of 1-2mm, consistent with the film moving direction, used as the tracking line of the optical probe of the rectification controller for positioning and edge trimming of the finished film and paper) on the bite side (width direction) of the holographic positioning deep groove lens nickel plate. The right side tracking line and the right pull specified position needle position line are also UV spliced on the background information by using the above UV splicing method, so the image feature thickness of the right side tracking line and the right pull specified position needle position line is also higher than the feature thickness of the background information (the feature thickness of the front pull specified position needle position line is also higher than the feature thickness of the background information, only because the front pull specified position needle position line is parallel to the circumference of the film, so the difference in feature thickness is greatly weakened in the width direction).

[0005] After the holographic nickel plate splicing is completed, a holographic deep groove lens nickel plate (sub-plate generation) is also needed to be made through the electroforming process. Since the image deep groove information of the master plate generation and the sub-plate generation is opposite, the groove depth of the background pattern information on the holographic deep groove lens nickel plate for UV molding is higher than the groove depth of the deep groove lens image, and similarly, the groove depth of the background pattern information is also higher than the groove depth of the right pull specified position needle position line and the right tracking line. When the UV light curing paint is pressed with the holographic deep groove lens nickel plate during UV molding, since the groove depth of the deep groove lens (including the right pull specified position needle position line and the right side tracking line) is lower than the groove depth of the background information on the holographic nickel plate, the groove depth of the UV light curing paint in the deep groove lens area, the right pull specified position needle position line and the right tracking line is higher than the groove depth of the background information (such as the groove depth of the deep groove lens area is 8um (feature thickness), the groove depth of the background information is 2-3um (feature thickness), and the groove depth of the right pull specified position needle position line and the right side tracking line is 4-5um (feature thickness)), which produces such structure is that the UV light curing paint is extruded between the molding steel roller and the molding rubber roller before curing (liquid state), and the thickness difference (including the reference thickness and the feature thickness) of the UV light curing after the difference in feature thickness of the deep groove holographic nickel plate surface.

[0006] The right pull gauge needle position line and the right tracking line are parallel to the direction of the film, and after the film is normally wound, the right pull gauge needle position line and the right tracking line will enter the wound state due to the higher thickness of the features than the surrounding background pattern information features, and with the increase of the winding meters, the thickness difference is amplified step by step, and when the winding reaches a certain meter number, the winding will produce wrinkles; the existing equipment often has a single function for adjusting the winding state of the UV mold press, and the existing winding equipment is difficult to specifically offset the influence of the thickness difference, so that the mold press winding length is usually less than 3000 meters (22uBOPET film), which seriously restricts the yield and production efficiency, and becomes a prominent bottleneck for the quality stability and efficient production of deep groove lens transfer paper. SUMMARY

[0007] To solve the above problems, a high adhesion deep groove lens transfer paper production equipment and its production process are provided, which utilizes the regularity of the rotation of the cam to adjust the winding state of the deep groove lens UV mold pressing film. The regularity of the rotation of the cam drives the support shaft to slide up and down, and the up and down sliding of the cam side drives the guide roller connected with the cam side to move up and down. Since the fixed side of the guide roller is fixed on the support, the guide roller connected with the cam side will have three states (the following analysis is based on the tangential mode of the winding material and the guide roller below (the structure is as follows): Figure 1 One is that the cam roller side of the guide roller is higher than the fixed side (the pressure applied to the winding material by the cam roller side is less than the pressure applied by the fixed roller side, so the winding material moves to the fixed roller side); the other is that the cam roller side of the guide roller is balanced with the fixed side (the pressure applied to the winding material by the cam roller side is consistent with the pressure applied by the fixed side, so the winding material moves to the reference point); and the last one is that the cam roller side of the guide roller is lower than the fixed side (the pressure applied to the winding material by the cam roller side of the guide roller is greater than the pressure applied by the fixed roller side, so the winding material moves to the cam side). The guide roller will move left and right once according to the above rules with one rotation of the cam, and the guide roller will move left and right periodically according to the above rules with the periodic rotation of the cam. The winding state of the deep groove lens UV mold pressing film can be specifically adjusted, and the problems such as wrinkles and film surface deformation that may occur during winding can be effectively improved, and the winding quality of the high adhesion deep groove lens UV mold pressing film can be improved.

[0017] A deep-line lens transfer card paper production process is applied to the above-mentioned high-adhesion deep-line lens transfer card paper production equipment, and includes the following steps:

[0018] S1, according to the printing file of the customer demand and the deep-line lens transfer card paper, the corresponding film is made;

[0019] S2, according to the film of S1, the deep-line lens nickel plate and the background holographic image are selected, and the deep-line lens nickel plate is made through the UV assembly and the electroforming process (the nickel plate includes but is not limited to deep-line lens information, background information, front pull gauge needle position line, right side tracking line, right pull gauge needle position line, etc.);

[0020] S3, the BOPET film is coated with water-based polyurethane paint by a gravure coater, dried in an oven and wound up to obtain a BOPET release film;

[0021] S4, the holographic deep line lens nickel plate with background information prepared in S2 is attached to the mold plate roller of a UV mold pressing machine;

[0022] S5, the release layer of the BOPET release film prepared in S3 is coated with UV light-cured paint by a coating device of the UV mold pressing machine, leveled by an oven of the UV mold pressing machine and reaches the UV mold pressing device;

[0023] S6, under the pressure of the UV mold pressing back pressure rubber roller, the UV light-cured paint on the BOPET release film is attached to the holographic deep line lens nickel plate on the UV mold plate roller to form a preset deep line structure, and UV curing treatment is performed to make the deep line structure fixed;

[0024] S7, after the deep line structure is shaped, it is transported to the entry guide roller along the winding direction, the cam on the support is started, and the deep line lens UV mold film passing through the guide roller is formed by the regularity of the structure characteristics of the cam in the rotating process, the pressure on both sides of the guide roller (assuming that the left side is the fixed side and the right side is the cam side) is regularly changed through the alternating action of the convex and the flat part of the cam (in the initial state, the pressure on both sides of the guide roller is balanced, and when the coiled material enters the winding roller, it is located at the center of the winding roller (the film edge reference point). When the guide roller rotates, assuming that the pressure on the cam side of the guide roller slowly increases, the coiled film is "pulled away" more strongly, so the coiled film edge will slide to the cam side (right side, away from the film edge reference point), so that the coiled film edge will produce a regularly deviated area (to the right) on the winding roller, and this area can convert the cumulative line height difference of the right tracking line and the right gauge needle line of the deep line lens and the thickness difference (reference thickness and feature thickness) of the background information area into a dispersed surface height difference; with the rotation of the cam, when the cam reaches the highest point, with the further rotation of the cam, the pressure on the cam side starts to decrease, and correspondingly, the coiled film will move to the left (close to the film edge reference point); when the cam rotates to the balance of the tension on the cam side and the fixed side, the pressure on both sides of the guide roller is balanced, and the coiled film edge is just located at the film edge reference point; with the further rotation of the cam, the pressure on the cam side will be less than that on the fixed side, and with the decrease of the pressure on the cam side, the coiled film edge will produce a leftward sliding force, so that the coiled film edge will move away from the film surface reference point, so that the coiled film edge will produce a regularly deviated area (to the left) on the winding roller, and this area can convert the cumulative line height difference of the right tracking line and the right gauge needle line of the deep line lens and the thickness difference (reference thickness and feature thickness) of the background information coating into a dispersed surface height difference; the cam moves as described above under the drive of the driving motor, and the final result of the movement converts the line cumulative thickness difference of the right tracking line, the right gauge needle line and the background information thickness difference (reference thickness and feature thickness) into a surface dispersed thickness difference, greatly improves the coiled film winding length, and avoids coiled film wrinkles and film surface deformation;

DETAILED DESCRIPTION

[0042] In order to further understand the features, technical means and specific purposes and functions reached by the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0043] As Figures 1 to 4 shown: a high adhesion deep groove lens transfer paper production equipment, including winding roller 1, winding roller 1 is provided with two mirror image support 2 on the side;Guide roller 21 is horizontally rotatable between the two supports 2, guide roller 21 is used for supporting and guiding deep groove lens UV mold pressing film 3 conveying;Deep groove lens UV mold pressing film 3 is connected with winding roller 1 after winding around guide roller 21;One of the supports 2 is provided with a rotatable cam 22, the cam 22 forms regular action on the deep groove lens UV mold pressing film 3 in the rotating process through its own structural characteristics, to adjust the winding state of deep groove lens UV mold pressing film 3.

[0044] The production equipment works, and the winding roller 1 is driven by the servo motor (not shown in the figure) to the deep groove lens UV mold pressing film 3 for winding operation. The deep groove lens UV mold pressing film 3 moves along the winding direction, first passes through the guide roller 21 between the two mirror-symmetrical supports 2, and the guide roller 21 rotates with the conveying of the deep groove lens UV mold pressing film 3 while supporting the deep groove lens UV mold pressing film 3, providing stable guidance and conveying support for the deep groove lens UV mold pressing film 3.

[0045] At the same time, the cam 22 on one of the supports 2 rotates, and the cam 22 forms a regular action on the deep groove lens UV mold pressing film 3 passing through the guide roller 21 due to its own structural characteristics during rotation. This action can be a periodic push-pull force generated by the direct contact between the cam 22 and the deep groove lens UV mold pressing film 3, or it can be through the contact between the cam 22 and the guide roller 21, thereby indirectly changing the tension distribution of the deep groove lens UV mold pressing film 3 through the guide roller 21, so that the deep groove lens UV mold pressing film 3 produces regular reciprocating adjustment or periodic balance of tension along its width direction during movement and winding to the winding roller 1. Specifically, when the convex part of the cam 22 acts on the deep groove lens UV mold pressing film 3 or the guide roller 21, the local stress of the deep groove lens UV mold pressing film 3 changes, prompting it to fine-tune to one side; when the flat part of the cam 22 acts, the deep groove lens UV mold pressing film 3 resets to the other side under the action of the winding tension, and this cycle forms a continuous regular adjustment. This adjustment can effectively offset the problem of uneven thickness of the right tracking line, right gauge needle line and background information coating (including reference thickness and feature thickness) after UV mold pressing photocuring of the deep groove lens UV mold pressing film 3, avoid wrinkles and poor adhesion of the deep groove lens transfer area of the deep groove lens UV mold pressing film 3 due to local tension imbalance during winding, and further realize the adjustment of the winding state of the deep groove lens UV mold pressing film 3, ensure the edge of the deep groove lens UV mold pressing film 3 after winding is neat (regular oscillation of the film edge), greatly reduce the thickness difference of the right tracking line, right gauge needle line (reference thickness and feature thickness) and background information cumulative thickness, improve the UV mold pressing meterage, and reduce production cost.

[0046] The two supports 2 provide a stable mounting base for the guide roller 21, ensuring that the guide roller 21 can stably support and guide the deep groove lens UV mold pressing film 3 during transportation, and ensuring the stability of the deep groove lens UV mold pressing film 3 before winding; the setting of the cam 22 can adjust the winding state of the deep groove lens UV mold pressing film 3 by using the regularity of its rotation process, effectively improving the possible wrinkling problem in the winding process, and improving the winding quality of the high adhesion deep groove lens transfer deep groove lens UV mold pressing film 3. The overall structure is compact, and through the cooperation of the guide roller 21 and the cam 22, the stability of the deep groove lens UV mold pressing film 3 is ensured while the winding state is optimized, which is suitable for the production requirements of the deep groove lens UV mold pressing film 3, and helps to improve the stability of the production process and the quality of the final product.

[0047] As shown in Figures 3 to 8 : One of the supports 2 is provided with a fixed shaft 23, and the other support 2 is provided with an arc-shaped slide rail 24 with the fixed shaft 23 as the center. One end of the guide roller 21 is rotationally connected with the fixed shaft 23, and the other end of the guide roller 21 is slidingly matched with the arc-shaped slide rail 24. The cam 22 can drive the end of the guide roller 21 close to the arc-shaped slide rail 24 by rotating.

[0048] During the rotation of the cam 22, the profile of the cam 22 will generate a regular pushing force on the end of the guide roller 21 matched with the arc-shaped slide rail 24. Since the arc-shaped slide rail 24 has the fixed shaft 23 as the center, the guide roller 21 will be pivoted at the fixed shaft 23 and drive the other end to reciprocate along the track of the arc-shaped slide rail 24 under the action of the pushing force. At the same time, the guide roller 21 can rotate around its own axis to support and transport the deep groove lens UV mold pressing film 3. This movement enables the guide roller 21 to change the contact angle with the deep groove lens UV mold pressing film 3 through its regular swing while maintaining stable transportation of the deep groove lens UV mold pressing film 3, thereby indirectly forming a more precise regularity on the deep groove lens UV mold pressing film 3.

[0049] Through the cooperation of the fixed shaft 23 and the arc-shaped slide rail 24, a clear track constraint is provided for the movement of the guide roller 21, ensuring that the swing of the guide roller 21 always revolves around the fixed shaft 23, avoiding unstable effects on the deep groove lens UV mold pressing film 3 due to movement deviation; the rotation connection and sliding cooperation of the two ends of the guide roller 21 not only ensure the flexibility of the swing, but also reduce the movement jamming through the guiding action of the arc-shaped slide rail 24, making the driving of the cam 22 on the guide roller 21 more smooth and efficient. This controllable motion transmission enables the guide roller 21 to adjust the deep groove lens UV mold pressing film 3 more stably, further improves the adjustment accuracy of the winding state of the deep groove lens UV mold pressing film 3, and helps to reduce the quality problems caused by unstable adjustment during winding, which meets the requirements of the deep groove lens UV mold pressing film 3 for winding accuracy.

[0050] AsFigures 3 to 8 and Figure 10 As shown: Cam 22 has a conical structure and is mounted on bracket 2, which can move along its own axis; a rotatable roller 212 is provided on one end of guide roller 21 near the arc-shaped slide rail 24, and roller 212 is engaged with the conical surface of cam 22.

[0051] During the rotation of cam 22, its conical outer circumference continuously contacts and rolls relative to roller 212. Because cam 22 is conical, different axial positions of the conical surface contacting roller 212 create varying thrusts, causing guide roller 21 to undulate along the curved slide rail 24 at one end. When adjusting the undulation of guide roller 21, cam 22 is moved along its own axis, changing the contact position between its conical surface and roller 212. When the contact position is close to the tip of cam 22, the conical surface inclination is smaller, resulting in less undulation of roller 212 and gentler undulation of guide roller 21. Conversely, when the contact position is close to the bottom of cam 22, the conical surface inclination is larger, resulting in greater undulation of roller 212 and more pronounced undulation of guide roller 21. Simultaneously, the rotatable nature of roller 212 reduces frictional resistance when in contact with the conical surface of cam 22, ensuring smoother operation.

[0052] By cooperating with the tapered cam 22 and the rotatable roller 212, the axial movement of the cam 22 can conveniently adjust the fluctuation of the guide roller 21. This eliminates the need to replace the cam 22, adapting to the winding adjustment requirements of different deep-textured lens UV molding films 3, thus improving the equipment's versatility and adjustment flexibility. The rotational setting of the roller 212 reduces frictional loss between it and the cam 22, extending the service life of the components. Furthermore, the stability of the tapered surface contact of the cam 22 ensures the regularity of the guide roller 21's fluctuation, making the adjustment of the winding state of the deep-textured lens UV molding film 3 more precise, further adapting to the high requirements for winding accuracy in transferring high-adhesion deep-textured lens UV molding films 3.

[0053] like Figures 5 to 10 As shown: The outer periphery of the roller 212 is provided with a plurality of rotatable balls 2121, which are distributed at equal intervals around the axis of the roller 212.

[0054] When the roller 212 contacts and moves relative to the conical surface of the cam 22, the ball 2121 directly contacts the conical surface of the cam 22. As the cam 22 rotates and the roller 212 undulates, the ball 2121 rotates flexibly according to the change in contact position, converting the sliding friction between the roller 212 and the cam 22 into the rolling friction of the ball 2121. This rolling contact effectively reduces the frictional resistance during relative movement, avoiding motion jamming or localized wear caused by excessive friction.

[0055] By setting a plurality of rotatable balls 2121 equidistantly distributed on the outer periphery of the roller 212, the friction loss between the roller 212 and the cam 22 is significantly reduced, the wear rate of the components is reduced, and the service life of the roller 212 and the cam 22 is prolonged; at the same time, the reduction of friction resistance makes the cooperation of the roller 212 and the cam 22 smoother, ensures that the fluctuation of the guide roller 21 is more stable and regular, and further ensures that the adjustment of the winding state of the deep groove lens UV mold pressing film 3 is more stable and accurate, and better adapts to the strict requirements of the winding precision in the production of the high-attached deep groove lens UV mold pressing film 3.

[0056] As shown in Figures 5 to 10 : The roller 212 is provided with two, and the guide roller 21 is provided with a support shaft 211 near one end of the arc-shaped slide rail 24, and the two rollers 212 are mirror-imaged and arranged at both ends of the support shaft 211; the cam 22 is correspondingly provided with two, and the two cams 22 can move in opposite directions to cooperate with the two rollers 212 respectively.

[0057] By synchronous rotation of the two cams 22, each roller 212 is in contact with the corresponding roller 212, and by moving the two cams 22 in opposite directions, the contact position of the two rollers 212 is adjusted respectively, and then the rollers 212 at both ends of the support shaft 211 are driven to produce corresponding fluctuations, so that the end of the guide roller 21 near the arc-shaped slide rail 24 swings stably along the arc-shaped slide rail 24. Because the two rollers 212 are mirror-imaged and correspondingly cooperate with the two cams 22, the forces on both ends of the guide roller 21 are more balanced during swinging, avoiding tilting or jamming caused by unilateral force, and the fluctuation amplitude of the guide roller 21 on both sides can be flexibly adjusted by the relative movement of the two cams 22, realizing targeted adjustment of different regions of the deep groove lens UV mold pressing film 3.

[0058] By corresponding cooperation of the double rollers 212 and the double cams 22, the swinging of the guide roller 21 is more stable and the force is more balanced, effectively reducing the problems of deep groove lens UV mold pressing film deviation or wrinkling that may be caused by unilateral adjustment; the two cams 22 can be relatively moved to flexibly adjust the acting amplitude on both sides according to the width, thickness and other characteristics of the deep groove lens UV mold pressing film 3, adapt to the winding requirements of deep groove lens UV mold pressing films 3 of different specifications, further improve the accuracy and adaptability of the adjustment, and ensure that the deep groove lens UV mold pressing film 3 maintains the edge neatness (the film edge swings regularly, the thickness difference between the right tracking line and the right pull rule needle position line and the background information is converted from cumulative thickness difference to dispersed surface thickness difference) during winding, and meets the high requirements for winding precision.

[0059] As shown in Figures 5 to 10As shown: support frame 221 is arranged on support frame 2 between two cams 22, and a rotatable drive shaft 2211 is arranged on support frame 221, both cams 22 are sleeved on drive shaft 2211, and cam 22 can slide along drive shaft 2211, and the top of support frame 221 is provided with a first rotary drive motor 2212 for rotating drive shaft 2211.

[0060] The rotation of drive shaft 2211 can drive two cams 22 to rotate synchronously, so that cam 22 can cooperate with corresponding roller 212 during rotation, and further drive guide roller 21 to swing regularly.

[0061] When it is necessary to adjust the contact position of cam 22 and roller 212 to change the fluctuation amplitude of guide roller 21, cam 22 can slide along the axial direction of drive shaft 2211, and at this time drive shaft 2211 still rotates to ensure that cam 22 does not interrupt the driving effect on guide roller 21 during position adjustment. Support frame 221 provides a unified support reference for drive shaft 2211, cam 22 and first rotary drive motor 2212, and ensures the coordination of the movement of each component.

[0062] The structure of drive shaft 2211 has the dual functions of rotation and allowing cam 22 to slide, which not only realizes the rotary drive of cam 22 to ensure that it continuously produces regular effect on guide roller 21, but also provides stable guidance for the position adjustment of cam 22, so that cam 22 can still maintain power transmission with drive shaft 2211 during adjustment, avoids the structural complexity problem caused by separately setting rotary and sliding drive mechanisms, improves the integration and operation convenience of the equipment; at the same time, this setting ensures the synchronism of cam 22 position adjustment and rotary drive, reduces the interference to the winding state of deep groove lens UV mold pressing film 3 during adjustment, further ensures the accuracy of adjustment and the stability of equipment operation, and is more suitable for the strict requirement of deep groove lens UV mold pressing film 3 production on winding accuracy.

[0063] Drive shaft 2211 can be provided as a spline shaft (the six-prism-shaped drive shaft 2211 in the figure is only schematic), and the outer circumferential surface thereof is provided with key teeth extending in the axial direction, and the inner holes of two cams 22 are correspondingly provided with key grooves matched with the key teeth. Through the cooperation of key teeth and key grooves, drive shaft 2211 can not only transmit rotary power to cam 22 to drive cam 22 to rotate synchronously, but also allow cam 22 to slide along the extension direction of key teeth.

[0064] As Figures 5 to 10As shown: The support 2 is provided with a mounting bracket 222 for supporting the rotation of the cam 22, two mounting brackets 222 are slidably arranged on the support 2, the support 2 is provided with a lead screw 2221 penetrating the two mounting brackets 222, and the two mounting brackets 222 are in threaded cooperation with the lead screw 2221, and the two ends of the lead screw 2221 have opposite screw threads.

[0065] The lead screw 2221 is driven by a servo motor, and when the lead screw 2221 rotates, the rotation of the lead screw 2221 will be converted into the relative sliding of the two mounting brackets 222 due to the opposite screw threads at the two ends of the lead screw 2221 and the threaded cooperation of the two mounting brackets 222 with the two ends of the lead screw 2221.

[0066] Through the cooperation of the lead screw 2221 and the double mounting brackets 222, the characteristics of the opposite screw threads at the two ends of the lead screw 2221 are used to make the sliding of the two mounting brackets 222 synchronous and opposite, ensuring the accurate and symmetrical adjustment of the relative positions of the two cams 22, avoiding the uneven force on the guide roller 21 caused by unilateral adjustment deviation; the sliding cooperation of the mounting bracket 222 and the support 2 provides stable guidance for the movement of the cam 22, reducing the shaking during adjustment; the transmission mode of the lead screw 2221 has the characteristics of self-locking, making the position adjustment of the cam 22 more stable and controllable, facilitating the accurate adjustment of the cooperation state of the cam 22 and the roller 212 according to the winding requirements of the deep groove lens UV mold pressing film 3, and further ensuring the adjustment of the guide roller 21 to the deep groove lens UV mold pressing film 3 more stable, improving the precision and reliability of the deep groove lens UV mold pressing film 3 winding process.

[0067] As shown in Figure 5 and Figure 6 The distance sensor 223 is arranged between the two cams 22 to monitor the distance between the two cams 22.

[0068] The distance between the two cams 22 is continuously monitored in real time by the distance sensor 223. When the two cams 22 slide relative to each other to adjust the position, the distance sensor 223 can synchronously capture the change in the distance between the two cams 22 and timely feedback the monitored distance information to the control part of the back end of the equipment, so that the operator or the control system can accurately control the relative position of the two cams 22, ensuring that the adjustment range of the two cams 22 is consistent with the preset requirements. This provides an accurate reference for the position adjustment of the cam 22, effectively avoids the deviation of the cam 22 and the roller 212 caused by excessive or insufficient adjustment, and further prevents the abnormal fluctuation of the guide roller 21 from affecting the winding state of the deep groove lens UV mold pressing film 3; at the same time, the real-time feedback of the distance information is conducive to realizing the automatic control of the position adjustment of the cam 22, reducing the manual operation error, improving the adjustment efficiency, and ensuring that the two cams 22 always maintain the relative position suitable for the winding requirement of the deep groove lens UV mold pressing film 3, thereby further ensuring the stability and precision of the winding process of the high deep groove lens UV mold pressing film 3.

[0069] As shown in Figures 1 to 4 , the second rotary drive motor 213 for driving the rotation of the guide roller 21 is arranged at one end of the guide roller 21 away from the arc-shaped sliding rail 24.

[0070] The rotation of the guide roller 21 around its own axis is driven by the start of the second rotary drive motor 213, which provides the driving force for the conveying of the deep groove lens UV mold pressing film 3, so that the deep groove lens UV mold pressing film 3 obtains stable traction during the movement around the guide roller 21 to the winding roller 1, ensuring that the conveying speed is uniform and controllable. At the same time, the guide roller 21 keeps rotating under the drive of the second rotary drive motor 213, which cooperates with the swinging action of the guide roller 21 driven by the cam 22, not only meeting the stable conveying requirement of the deep groove lens UV mold pressing film 3, but also adjusting the winding state through swinging. The two work together to ensure that the deep groove lens UV mold pressing film 3 can move smoothly and be adjusted accurately in the conveying process. The driving position is arranged at the end away from the arc-shaped sliding rail 24, which can avoid interference with the swinging structure of the guide roller 21, ensure that the two actions do not affect each other, and work efficiently, further improve the stability and reliability of the equipment for conveying and adjusting the winding of the deep groove lens UV mold pressing film 3, and better meet the strict requirements of the deep groove lens UV mold pressing film 3 on conveying precision and winding quality.

[0071] As shown in Figures 1 to 4 , a deep groove lens transfer paper production process is applied to the above-mentioned high-adhesion deep groove lens transfer paper production equipment, which comprises the following steps:

[0072] S1, according to the customer's demand and the printing file of the deep groove lens transfer paper, the corresponding film is made;

[0073] S2, according to S1, the film, select deep groove lens nickel and background holographic image, through UV layout and electroforming process, the production of deep groove lens nickel (nickel including but not limited to deep groove lens information, background information, front pull gauge needle position line, right tracking line, right pull gauge needle position line, etc.);

[0074] S3, BOPET BOPET film through the gravure coater, full coating water-based polyurethane coating, drying oven drying and winding, BOPET release film is prepared;

[0075] S4, the holographic deep groove lens nickel containing background information prepared by S2 is pasted on the mold pressing roll of UV mold pressing machine;

[0076] S5, the release layer of BOPET release film prepared by S3 is full coated with UV photocuring coating on the coating device of UV mold pressing machine, and after leveling by UV mold pressing machine oven, it reaches UV mold pressing device;

[0077] S6, under the pressure of the UV mold back pressure roller, the UV light curing coating on the BOPET release film is attached to the holographic deep groove lens nickel plate on the UV mold plate roller to form a preset deep groove, and at the same time, UV curing treatment is carried out to make the deep groove structure fixed; S7, after the deep groove structure is fixed, it is conveyed to the entry guide roller in the winding direction, the cam on the support is started, and the regular action on the BOPET deep groove lens UV mold film passing through the guide roller is formed through the structural characteristics of the cam in the rotating process. Through the alternating action of the convex and gentle parts of the cam, the pressure on both sides of the guide roller (assuming the left side is the fixed side and the right side is the cam side) changes regularly (in the initial state, the pressure on both sides of the guide roller is balanced, and when the coiled film enters the winding roller, it is located at the center of the winding roller (film edge reference point). When the guide roller rotates, assuming that the pressure on the cam side of the guide roller increases slowly, the coiled film is "pulled away" more strongly, so the coiled film edge will slide to the cam side (right side, away from the film edge reference point), so that the coiled film edge will produce a regularly offset area (to the right) on the winding roller. This area can convert the cumulative line height difference of the right tracking line and the right gauge needle line of the deep groove lens and the thickness difference (reference thickness and feature thickness) of the background information area from a cumulative line height difference to a dispersed surface height difference; as the cam rotates, when the cam reaches the highest point, as the cam further rotates, the pressure on the cam side begins to decrease, and correspondingly, the coiled film will move to the left (close to the film edge reference point); when the cam rotates to the point where the tension on the cam side and the fixed side is balanced, the pressure on both sides of the guide roller is balanced, and the coiled film edge is located at the film edge reference point; as the cam further rotates, the pressure on the cam side will be less than that on the fixed side, and as the pressure on the cam side decreases, the coiled film edge will produce a leftward sliding force, causing the coiled film edge to move away from the film surface reference point. Thus, the coiled film edge will produce a regularly offset area (to the left) on the winding roller. This area can convert the cumulative line height difference of the right tracking line and the right gauge needle line of the deep groove lens and the thickness difference (reference thickness and feature thickness) of the background information coating from a cumulative line height difference to a dispersed surface height difference; the cam moves as described above under the drive of the driving motor. The final result of the movement converts the thickness difference (reference thickness and feature thickness) of the right tracking line, the right gauge needle line and the background information from a line cumulative thickness difference to a surface dispersed thickness difference, greatly improving the coiled film winding length, while avoiding coiled film wrinkles and film surface deformation;

[0078] S8, before the coiled film reaches the winding roller, the UV light curing coating is treated by corona device, and after corona treatment, the coiled film is wound to produce a high-adhesion deep groove lens BOPET transfer film;

[0079] S9, the high adhesion deep groove lens BOPET transfer film prepared in S8 is plated with aluminum, slit, compounded with paper, peeled, positioned and cut to prepare a high adhesion deep groove lens transfer card paper; the above examples only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
