Description
Technical Field
[0001] This invention relates to the field of optical adhesive processing technology, specifically to a pressure roller device for preventing re-adhesion in optical adhesive processing of mixed substrates. Background Technology
[0002] Optical adhesive, being a type of adhesive without a substrate and possessing a certain degree of fluidity, is prone to problems such as adhesive overflow and deformation during processing due to pressure. This can lead to re-adhesion between the adhesive and the pressure-applying structure, which in turn hinders product processing.
[0003] Patent publication number CN223131581U discloses a pressure roller device and an optical adhesive bonding machine for preventing re-adhesion in optical adhesive processing. The pressure roller device includes a support rod, a driven gear, and two sets of pressure rollers. The driven gear is fixed to the support rod and receives external rotational power, transmitting it to the support rod. The two sets of pressure rollers are fitted onto the support rod and can move axially along the support rod to adjust their spacing. Each pressure roller is equipped with a locking element to lock it to the support rod after it has moved to a preset position. This improved pressure roller device allows for adjustment of the spacing between the two sets of pressure rollers, making it suitable for processing different types of optical adhesive products. It avoids pressing directly onto the optical adhesive product, effectively reducing re-adhesion and preventing adhesive overflow and deformation.
[0004] However, the device still has shortcomings: the device reduces back-adhesion by adjusting the distance between the two sets of pressure rollers, but when the two ends of the pressure roller device are in contact with the optical adhesive waste and are not cut, the waste part is the undivided part of the optical adhesive as a whole. When the waste material sticks back with the pressure roller, it is easy to pull the optical adhesive bonding part, which can easily cause the optical adhesive to lift up and detach from the substrate bonding surface. At the same time, if the optical adhesive is not relatively cooled and hardened during cutting, it will increase the difficulty of cutting. And if air is not vented during the bonding process, air bubbles can easily grow between the substrate and the optical adhesive, thereby reducing the bonding strength between the optical adhesive bonding part and the substrate. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a pressure roller device for preventing re-adhesion in the processing of optical adhesives for hybrid substrates, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure roller device for preventing re-adhesion in optical adhesive processing of mixed substrates, comprising a main body, an operating table inside the main body, two sliding frames symmetrically and fixedly installed on the inner sidewall of the main body, an electric push rod slidably installed inside the sliding frames, an electric slide rail fixedly installed on the top of the inner wall of the main body, a vertical rod slidably installed inside the electric slide rail, a U-shaped telescopic plate penetrating and fixedly installed on the outer wall of the vertical rod, a separating device for accelerating the cooling of the optical adhesive and facilitating cutting above the U-shaped telescopic plate, an anti-bubble device for venting air during optical adhesive bonding around the separating device, a sidewall of the telescopic end of the U-shaped telescopic plate fixedly installed on the outer wall of the telescopic end of the electric push rod, pressure rollers rotatably installed on the inner sidewall of the telescopic end of the U-shaped telescopic plate, a telescopic pressure roller fixedly installed between several pressure rollers on their respective sides, a crossbar fixedly installed on the side of the pressure roller away from the telescopic pressure roller, and a gear fixedly installed on the end of the crossbar away from the pressure roller.
[0007] According to the above technical solution, a fixed plate is fixedly installed on the right side of the telescopic end of the U-shaped telescopic plate. A rotating rod is rotatably installed through the fixed plate. A conveyor belt is installed between the rotating rod and the outer wall of the crossbar. A cutting blade is fixedly installed at the end of the rotating rod away from the conveyor belt. A scraping block is fixedly installed on the outer wall of the fixed plate. Two exhaust grooves are symmetrically opened on the top of the main body of the device. Toothed grooves are opened at both ends of the top of the operating table. The electric push rod is telescopic. The outer wall of the pressure roller presses the unbonded part of the optical adhesive. Both ends of the telescopic pressure roller are telescopic, and the outer wall of the middle end of the telescopic pressure roller contacts the bonded part of the optical adhesive. The gear provides rotational force for the pressure roller.
[0008] According to the above technical solution, the telescopic end of the U-shaped telescopic plate is hollowed out, and a spring is built into the U-shaped telescopic plate. The outer wall of the crossbar moves through the interior of the telescopic end of the U-shaped telescopic plate. The gear meshes with the tooth groove on the top of the operating table. The cutting blade separates the waste material of the optical adhesive from the bonding material. The outer wall of the cutting blade is located inside the scraper block. When the electric push rod is activated, the telescopic end of the electric push rod pushes the side wall of the telescopic end of the U-shaped telescopic plate. At this time, the telescopic end of the U-shaped telescopic plate begins to retract. The U-shaped telescopic plate drives the pressure roller to move synchronously. The pressure roller pushes the telescopic end of the telescopic pressure roller to retract, thereby completing the orientation adjustment of the pressure roller for different sizes of optical adhesive. Then, the electric slide rail is activated. The electric slide rail drives the vertical rod to move horizontally. The vertical rod drives the U-shaped telescopic plate to move synchronously. The telescopic end of the U-shaped telescopic plate pulls the electric push rod to slide horizontally along the interior of the sliding frame. The telescopic end of the push rod is always in contact with the telescopic end of the U-shaped telescopic plate. At the same time, the U-shaped telescopic plate drives the crossbar to move synchronously. When the crossbar drives the gear to move horizontally, the meshing of the operating table tooth groove causes the gear to generate a rotational force. Through the transmission of force, the pressure roller and the telescopic pressure roller rotate. That is, the pressure roller causes the telescopic pressure roller to rotate and move horizontally. At this time, the pressure roller rotates and contacts the optical adhesive waste part, and the telescopic end of the telescopic pressure roller rotates and applies pressure to the top of the optical adhesive and the substrate bonding part. When the crossbar rotates, the conveyor belt drives the rotating rod to rotate. When the rotating rod rotates inside the fixed plate, it drives the cutting blade to rotate. That is, the cutting blade moves horizontally with the U-shaped telescopic plate in a rotating posture. At this time, the cutting blade rotates and cuts the waste material in contact with the pressure roller. At the same time, the cutting blade continuously contacts the inside of the scraper block when it rotates. The scraper block scrapes and maintains the surface of the cutting blade.
[0009] According to the above technical solution, the separating device includes a U-shaped plate, which is internally penetrated and fixedly installed on the outer wall of the vertical rod. The U-shaped plate is located above the U-shaped telescopic plate. Two friction wheels are symmetrically and rotatably installed on the inner sidewall of the U-shaped plate. A reciprocating screw is fixedly installed on the side of the friction wheel away from the vertical rod. A cooling mechanism is movably installed through the outer wall of the reciprocating screw. A limit plate is fixedly installed on the outer sidewall of the U-shaped plate.
[0010] According to the above technical solution, the outer wall of the friction wheel contacts the top of the inner wall of the device body, the outer wall of the reciprocating screw moves through the interior of the U-shaped plate, and the outer wall of the reciprocating screw is a non-self-locking reciprocating spiral groove. The cooling mechanism promotes the relative hardening of the optical adhesive through cold air. The outer wall of the limiting plate is installed inside the cooling mechanism through and slidingly. The vertical rod drives the U-shaped plate to move horizontally, and the U-shaped plate drives the friction wheel to move horizontally along the top of the inner wall of the device body, thereby generating friction. When the friction wheel rotates due to friction, it drives the reciprocating screw to rotate. The reciprocating screw is driven by the non-self-locking reciprocating spiral groove on its own outer wall, causing the cooling mechanism to slide horizontally along itself and the outer wall of the limiting plate and reset. This process is repeated, and at this time, the cooling mechanism provides uniform cooling treatment for the pressure roller, cutting blade, and optical adhesive.
[0011] According to the above technical solution, a linkage frame is slidably installed on the fixed end sidewall of the U-shaped telescopic plate via a spring. A negative pressure mechanism is slidably installed on one side of each other within the linkage frame via a spring. The negative pressure mechanism is located above the telescopic pressure roller. Two trapezoidal frames are symmetrically and fixedly installed at the top edge of the linkage frame. A contact plate is fixedly installed on the side of the cooling mechanism near the friction wheel. The bottom of the contact plate is designed with the slope of the trapezoidal frame, and the contact plate has an L-shaped hollow design. The cooling mechanism drives the contact plate to move horizontally. The bottom of the contact plate pushes the slope of the trapezoidal frame, causing it to generate a downward force. At this time, the trapezoidal frame presses the linkage frame to slide downward along the fixed end sidewall of the U-shaped telescopic plate. The trapezoidal frame drives the negative pressure mechanism to move towards the telescopic pressure roller. Afterward, when the linkage frame returns to its original position due to the spring force, the negative pressure mechanism returns to its original position, which indirectly shortens the distance between the negative pressure mechanism and the telescopic pressure roller.
[0012] According to the above technical solution, the anti-bubble device includes a horizontal plate, the side wall of which is fixedly installed on the left side of the linkage frame. Two telescopic inclined plates are symmetrically and hinged to the left side of the horizontal plate by a torsion spring. A rotating roller is rotatably installed on the left side of the telescopic end of the telescopic inclined plate. An L-shaped telescopic plate is fixedly installed at the center of the bottom of the horizontal plate. A cylinder is rotatably installed inside the telescopic end of the L-shaped telescopic plate.
[0013] According to the above technical solution, the telescopic inclined plate is elastically designed, the L-shaped telescopic plate has a built-in spring, and the telescopic end of the L-shaped telescopic plate is hollow. The outer wall of the cylinder protrudes from the bottom of the L-shaped telescopic plate. The linkage frame drives the horizontal plate to move downward and reset. The horizontal plate drives the telescopic inclined plate to move synchronously. The telescopic inclined plate drives the rotating roller to move synchronously. The descending rotating roller contacts the top of the optical adhesive bonding part and generates a resistance force. The resistance force causes the telescopic inclined plate to generate a rotational force. When the telescopic inclined plate drives the rotating roller to move along the hinge axis in an arc trajectory, the rotating roller moves from the top center of the optical adhesive towards the edge. At the same time, when the horizontal plate drives the L-shaped telescopic plate to descend, the L-shaped telescopic plate drives the cylinder to move synchronously. The cylinder contacts the top of the optical adhesive before the rotating roller. The outer wall of the cylinder applies downward pressure to the top center of the optical adhesive.
[0014] According to the above technical solution, two L-shaped support plates are symmetrically and fixedly installed at the top edge of the horizontal plate. A long rod is fixedly built into the exhaust groove of the main body of the device. An activated carbon plate is rotatably installed on the outer wall of the long rod through a torsion spring. The bottom of the activated carbon plate contacts the top of the L-shaped support plate. When the horizontal plate moves the L-shaped support plate downward, the L-shaped support plate releases its support on the activated carbon plate. At this time, the activated carbon plate rotates along the outer wall of the long rod through the elastic force of the torsion spring, that is, the activated carbon plate releases its blockage on the top of the main body of the device. When the L-shaped support plate resets, it pushes the activated carbon plate to reset. This process is repeated to make the activated carbon plate continuously rotate.
[0015] This invention provides a pressure roller device for preventing re-adhesion during the processing of optical adhesives on hybrid substrates. It offers the following advantages: (1) The present invention uses an electric push rod, an electric slide rail, a vertical rod, a U-shaped telescopic plate, a pressure roller, a telescopic pressure roller, a horizontal rod, a gear, a fixed plate, a rotating rod, a conveyor belt, a cutting blade, and a scraper block to cooperate. The electric push rod realizes the automated and simplified adjustment of the pressure roller spacing to cope with the processing of optical adhesive of different sizes, and prevents deformation or back-adhesion caused by contact with the optical adhesive bonding part. At the same time, the gear makes the pressure roller revolve, thereby reducing the friction when in contact with the optical adhesive waste, and effectively avoiding the pressure roller static contact with the optical adhesive waste to generate a pushing force. The cutting blade rotates to cut and separate the optical adhesive waste from the bonding part. On the original basis, it further avoids the phenomenon of back-adhesion between the waste part and the pressure roller, which causes pulling on the bonding part between the optical adhesive and the substrate, and prevents the optical adhesive from lifting up due to pulling and detaching from the substrate bonding surface, thus optimizing the bonding strength. At the same time, the scraper block removes the adhesive on the surface of the cutting blade to ensure cutting efficiency.
[0016] (2) The present invention, through the setting of the separation device, through the cooperation of the vertical rod, U-shaped plate, friction wheel, reciprocating screw, cooling mechanism, limiting plate, linkage frame, negative pressure mechanism, trapezoidal frame and contact plate, expands the uniform cooling range of the cooling mechanism through the reciprocating screw, promotes the relative cooling and hardening of the optical adhesive waste part, reduces its adhesion to the pressure roller and cutting blade, further avoids the re-adhesion phenomenon, and facilitates the rapid cutting of the cutting blade, avoiding the optical adhesive waste part being incompletely separated and causing a certain pulling on the bonding part; the contact plate indirectly shortens the distance between the negative pressure mechanism and the telescopic pressure roller, preventing the surface temperature change of the telescopic pressure roller caused by the constant fixed-point pulling, thus preventing the generation of water vapor, avoiding interference with the optical adhesive pressing, and at the same time, the negative pressure mechanism ensures the surface of the telescopic pressure roller is clean, preventing the adhesion of adhesive or impurities after hardening, and preventing the optical adhesive surface wear from causing a decrease in clarity.
[0017] (3) The present invention uses an anti-bubble device, which works in conjunction with a linkage frame, a horizontal plate, a telescopic inclined plate, a rotating roller, an L-shaped telescopic plate, a cylinder, an L-shaped support plate, a long rod and an activated carbon plate. The cylinder limits the center of the optical adhesive, which effectively prevents the rotating roller from moving in an arc trajectory and causing the optical adhesive to shift from the substrate. At the same time, the rotating roller smooths the optical adhesive during its movement, ensuring the flatness of the optical adhesive and expelling the air trapped between the substrate and the optical adhesive, thus preventing the formation of bubbles between the two after the telescopic pressure roller presses them together. The flipping of the activated carbon plate causes the gas inside the device to be replaced with the outside air at a relatively slow rate, which prevents the accumulation of harmful substances and keeps the temperature inside the device relatively low, ensuring that the optical adhesive is always in a relatively hardened state and preventing it from softening too much and affecting the processing.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Please see Figures 1-8One embodiment of the present invention is: a pressure roller device for preventing re-adhesion in optical adhesive processing of mixed substrates, comprising a device body 1, an operating table 2 inside the device body 1, two sliding frames 3 symmetrically and fixedly installed on the inner sidewall of the device body 1, an electric push rod 4 slidably installed inside the sliding frame 3, an electric slide rail 5 fixedly installed on the top of the inner wall of the device body 1, a vertical rod 6 slidably installed inside the electric slide rail 5, a U-shaped telescopic plate 7 penetrating and fixedly installed on the outer wall of the vertical rod 6, a separating device 17 above the U-shaped telescopic plate 7 to accelerate the cooling of the optical adhesive and facilitate cutting, an anti-bubble device 18 for venting air during optical adhesive bonding around the separating device 17, a sidewall of the telescopic end of the U-shaped telescopic plate 7 fixedly installed on the outer wall of the telescopic end of the electric push rod 4, a pressure roller 8 rotatably installed on the inner sidewall of the telescopic end of the U-shaped telescopic plate 7, a telescopic pressure roller 9 fixedly installed between several pressure rollers 8 close to each other, a crossbar 10 fixedly installed on the side of the pressure roller 8 away from the telescopic pressure roller 9, and a gear 11 fixedly installed on the end of the crossbar 10 away from the pressure roller 8.
[0022] A fixed plate 12 is fixedly installed on the right side of the telescopic end of the U-shaped telescopic plate 7. A rotating rod 13 is installed through and rotatably inside the fixed plate 12. A conveyor belt 14 is installed between the rotating rod 13 and the outer wall of the crossbar 10. A cutting blade 15 is fixedly installed at the end of the rotating rod 13 away from the conveyor belt 14. A scraper block 16 is fixedly installed on the outer wall of the fixed plate 12. Two exhaust slots are symmetrically opened on the top of the main body 1. Toothed grooves are opened at both ends of the top of the operating table 2. The electric push rod 4 is telescopic. The outer wall of the pressure roller 8 presses the part of the optical adhesive that is not bonded. Both ends of the telescopic pressure roller 9 are telescopic. The outer wall of the middle end of the telescopic pressure roller 9 contacts the part of the optical adhesive that is bonded. The gear 11 provides rotational force for the pressure roller 8.
[0023] The telescopic end of the U-shaped telescopic plate 7 has a hollow design, and the U-shaped telescopic plate 7 has a built-in spring. The outer wall of the crossbar 10 moves through the inside of the telescopic end of the U-shaped telescopic plate 7. The gear 11 meshes with the tooth groove on the top of the operating table 2. The cutting blade 15 separates the waste material of the optical adhesive from the bonding. The outer wall of the cutting blade 15 is located inside the scraping block 16.
[0024] The spacing of the pressure roller 8 is automatically and simply adjusted by the electric push rod 4 to handle optical adhesives of different sizes, preventing deformation or re-adhesion caused by contact with the adhesive bonding part. At the same time, the gear 11 causes the pressure roller 8 to rotate, thereby reducing the friction when in contact with the optical adhesive waste and effectively avoiding the pulling force generated by the static contact of the pressure roller 8 with the optical adhesive waste. The rotating cutting blade 15 separates the optical adhesive waste from the bonding part, further preventing the waste part from re-adheding between the pressure roller 8 and the substrate, thus preventing the optical adhesive from lifting and detaching from the substrate bonding surface due to pulling, optimizing the bonding strength. At the same time, the scraper block 16 removes the adhesive on the surface of the cutting blade 15, ensuring cutting efficiency.
[0025] In use, the electric push rod 4 is activated. The telescopic end of the electric push rod 4 pushes the side wall of the telescopic end of the U-shaped telescopic plate 7, at which point the telescopic end of the U-shaped telescopic plate 7 begins to retract. The U-shaped telescopic plate 7 drives the pressure roller 8 to move synchronously. The pressure roller 8 pushes the telescopic end of the telescopic pressure roller 9 to retract, thus completing the orientation adjustment of the pressure roller 8 for different sizes of optical adhesive. Then, the electric slide rail 5 is activated. The electric slide rail 5 drives the vertical rod 6 to move horizontally. The vertical rod 6 drives the U-shaped telescopic plate 7 to move synchronously. The telescopic end of the U-shaped telescopic plate 7 pulls the electric push rod 4 to slide horizontally along the inside of the sliding frame 3, that is, the telescopic end of the electric push rod 4 is always in contact with the telescopic end of the U-shaped telescopic plate 7. At the same time, the U-shaped telescopic plate 7 drives the horizontal rod 10 to move synchronously. When the horizontal rod 10 drives the gear 11 to move horizontally, it relies on the tooth groove of the operating table 2. The meshing causes the gear 11 to generate a rotational force, which, through the transmission of force, causes the pressure roller 8 and the telescopic pressure roller 9 to rotate. That is, the pressure roller 8 causes the telescopic pressure roller 9 to rotate and move horizontally. At this time, the pressure roller 8 rotates and contacts the optical adhesive waste part, and the telescopic end of the telescopic pressure roller 9 applies rotational pressure to the top of the optical adhesive and the substrate bonding part for bonding. When the crossbar 10 rotates, it causes the rotating rod 13 to rotate through the transmission of the conveyor belt 14. When the rotating rod 13 rotates inside the fixed plate 12, it drives the cutting blade 15 to rotate. That is, the cutting blade 15 moves horizontally with the U-shaped telescopic plate 7 in a rotating posture. At this time, the cutting blade 15 rotates and cuts the waste material contacted by the pressure roller 8. At the same time, when the cutting blade 15 rotates, it continuously contacts the inside of the scraper block 16. The scraper block 16 scrapes and maintains the surface of the cutting blade 15.
[0026] According to the above embodiments, the spacing adjustment of the pressure roller 8 is automated and simplified by the electric push rod 4 to cope with the processing of optical adhesive of different sizes, preventing deformation or re-adhesion caused by contact with the optical adhesive bonding part. At the same time, the gear 11 causes the pressure roller 8 to revolve, thereby reducing the friction when in contact with the optical adhesive waste, effectively avoiding the pushing force generated by the static contact of the pressure roller 8 with the optical adhesive waste. The rotation of the cutting blade 15 is used to separate the optical adhesive waste from the bonding part, further preventing the waste part from re-adheding between the pressure roller 8 and the bonding part of the optical adhesive and the substrate, preventing the optical adhesive from lifting up due to pulling and detaching from the substrate bonding surface, optimizing the bonding strength. At the same time, the scraper block 16 removes the adhesive on the surface of the cutting blade 15 to ensure cutting efficiency.
[0027] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a separating device 17; The separating device 17 includes a U-shaped plate 171, which is internally penetrated and fixedly installed on the outer wall of the vertical rod 6. The U-shaped plate 171 is located above the U-shaped telescopic plate 7. Two friction wheels 172 are symmetrically and rotatably installed on the inner side wall of the U-shaped plate 171. A reciprocating screw 173 is fixedly installed on the side of the friction wheel 172 away from the vertical rod 6. A cooling mechanism 174 is movably installed through the outer wall of the reciprocating screw 173. A limit plate 175 is fixedly installed on the outer side wall of the U-shaped plate 171.
[0028] The outer wall of the friction wheel 172 contacts the top of the inner wall of the device body 1. The outer wall of the reciprocating screw 173 moves through the interior of the U-shaped plate 171. The outer wall of the reciprocating screw 173 is a non-self-locking reciprocating spiral groove. The cooling mechanism 174 causes the optical adhesive to harden relatively through the cold air. The outer wall of the limiting plate 175 passes through and slides inside the cooling mechanism 174.
[0029] A linkage frame 176 is slidably installed on the fixed end side wall of the U-shaped telescopic plate 7 via a spring. A negative pressure mechanism 177 is slidably installed on one side of the linkage frame 176 via a spring. The negative pressure mechanism 177 is located above the telescopic pressure roller 9. Two trapezoidal frames 178 are symmetrically and fixedly installed at the top edge of the linkage frame 176. A contact plate 179 is fixedly installed on the side of the cooling mechanism 174 near the friction wheel 172. The bottom of the contact plate 179 is designed with an inclined surface to the trapezoidal frame 178, and the contact plate 179 is an L-shaped hollow design.
[0030] The reciprocating screw 173 expands the cooling range of the cooling mechanism 174, promoting the relative cooling and hardening of the optical adhesive waste portion. This reduces its adhesion to the pressure roller 8 and the cutting blade 15, further preventing re-adhesion. It also facilitates rapid cutting by the cutting blade 15, preventing incomplete separation of the optical adhesive waste portion and avoids pulling on the bonding part. The contact plate 179 indirectly shortens the distance between the negative pressure mechanism 177 and the telescopic pressure roller 9, preventing the temperature change of the surface of the telescopic pressure roller 9 caused by constant fixed-point pulling, which would generate moisture and interfere with the optical adhesive bonding. At the same time, the negative pressure mechanism 177 ensures the cleanliness of the surface of the telescopic pressure roller 9, preventing the adhesion of adhesive or impurities after hardening and preventing the optical adhesive surface from being worn, which would reduce clarity.
[0031] In use, the vertical rod 6 drives the U-shaped plate 171 to move horizontally. The U-shaped plate 171 drives the friction wheel 172 to move horizontally along the top of the inner wall of the main body 1, thereby generating friction. When the friction wheel 172 rotates due to friction, it drives the reciprocating screw 173 to rotate. The reciprocating screw 173, driven by the non-self-locking reciprocating spiral groove on its outer wall, causes the cooling mechanism 174 to slide horizontally along itself and the outer wall of the limiting plate 175 and then reset. This process is repeated. At this time, the cooling mechanism 174 cools the pressure roller 8, the cutting disc 15, and the optical adhesive, etc. Uniform cooling is performed; the cooling mechanism 174 drives the contact plate 179 to move horizontally, and the bottom of the contact plate 179 pushes the inclined surface of the trapezoidal frame 178 to generate a downward force. At this time, the trapezoidal frame 178 presses the linkage frame 176 to slide downward along the side wall of the fixed end of the U-shaped telescopic plate 7. The trapezoidal frame 178 drives the negative pressure mechanism 177 to move closer to the telescopic pressure roller 9. Afterwards, when the linkage frame 176 returns to its original position due to the spring force, the negative pressure mechanism 177 returns to its original position, which indirectly shortens the distance between the negative pressure mechanism 177 and the telescopic pressure roller 9.
[0032] According to the above embodiments, the reciprocating screw 173 expands the cooling range of the cooling mechanism 174, causing the optical adhesive waste to cool and harden relatively, reducing its adhesion to the pressure roller 8 and the cutting blade 15, further preventing re-adhesion, and facilitating rapid cutting by the cutting blade 15, avoiding incomplete separation of the optical adhesive waste and causing some pulling on the bonding part; the contact plate 179 indirectly shortens the distance between the negative pressure mechanism 177 and the telescopic pressure roller 9, preventing the surface temperature change of the telescopic pressure roller 9 caused by constant fixed-point pulling, thus preventing the generation of water vapor and avoiding interference with the optical adhesive bonding, while the negative pressure mechanism 177 ensures the surface of the telescopic pressure roller 9 is clean, preventing the adhesion of adhesive or impurities after hardening, and preventing the optical adhesive surface from being worn and causing a decrease in clarity.
[0033] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an anti-bubble device 18; The anti-bubble device 18 includes a horizontal plate 181. The side wall of the horizontal plate 181 is fixedly installed on the left side of the linkage frame 176. Two telescopic inclined plates 182 are symmetrically connected and hinged to the left side of the horizontal plate 181 by torsion springs. A rotating roller 183 is rotatably installed on the left side of the telescopic end of the telescopic inclined plate 182. An L-shaped telescopic plate 184 is fixedly installed at the center of the bottom of the horizontal plate 181. A cylinder 185 is rotatably installed inside the telescopic end of the L-shaped telescopic plate 184.
[0034] The telescopic ramp 182 is designed to be flexible, the L-shaped telescopic ramp 184 has a built-in spring, and the telescopic end of the L-shaped telescopic ramp 184 is hollow. The outer wall of the cylinder 185 protrudes from the bottom of the L-shaped telescopic ramp 184.
[0035] Two L-shaped support plates 186 are symmetrically and fixedly installed at the top edge of the horizontal plate 181. A long rod 187 is fixedly built into the exhaust groove of the main body 1 of the device. An activated carbon plate 188 is rotatably installed on the outer wall of the long rod 187 through a torsion spring. The bottom of the activated carbon plate 188 contacts the top of the L-shaped support plate 186.
[0036] The cylinder 185 limits the center of the optical adhesive, effectively preventing the optical adhesive from shifting from the substrate due to the arc-shaped trajectory movement of the roller 183. At the same time, the roller 183 smooths the optical adhesive during its movement, ensuring the flatness of the adhesive bonding and expelling the air trapped between the substrate and the optical adhesive, thus preventing air bubbles from forming between the two after the telescopic pressure roller 9 presses them together. The flipping of the activated carbon plate 188 causes the gas inside the device body 1 to exchange with the outside air at a relatively slow rate, preventing the accumulation of harmful substances and keeping the internal temperature of the device body 1 relatively low at all times, ensuring that the optical adhesive is in a relatively hardened state and preventing it from softening too much and affecting processing.
[0037] In use, the linkage frame 176 drives the horizontal plate 181 to move downwards and then reset. The horizontal plate 181 drives the telescopic inclined plate 182 to move synchronously, and the telescopic inclined plate 182 drives the rotating roller 183 to move synchronously. The descending rotating roller 183 contacts the top of the optical adhesive bonding part, generating a resistance force. This resistance force causes the telescopic inclined plate 182 to rotate. When the telescopic inclined plate 182 drives the rotating roller 183 to move along the hinge axis in an arc-shaped trajectory, the rotating roller 183 moves from the top center of the optical adhesive towards the edge. At the same time, when the horizontal plate 181 drives the L-shaped telescopic plate 184 to descend, the L-shaped telescopic plate 184... The cylinder 185 moves synchronously, and the cylinder 185 contacts the top of the optical adhesive before the rotating roller 183. The outer wall of the cylinder 185 applies downward pressure to the center of the top of the optical adhesive. When the horizontal plate 181 drives the L-shaped support plate 186 to move downward, the L-shaped support plate 186 releases its support on the activated carbon plate 188. At this time, the activated carbon plate 188 rotates along the outer wall of the long rod 187 by the elastic force of the torsion spring. That is, the activated carbon plate 188 releases its seal on the top of the main body 1 of the device. When the L-shaped support plate 186 resets, it pushes the activated carbon plate 188 to reset. This process is repeated to make the activated carbon plate 188 continuously rotate.
[0038] According to the above embodiment, the cylinder 185 limits the center of the optical adhesive, effectively preventing the optical adhesive from shifting with the substrate due to the arc-shaped trajectory movement of the roller 183. At the same time, the roller 183 smooths the optical adhesive during its movement, ensuring the flatness of the optical adhesive bonding and expelling the air trapped between the substrate and the optical adhesive, thus preventing air bubbles from forming between the two after the telescopic pressure roller 9 presses them together. The flipping of the activated carbon plate 188 causes the gas inside the device body 1 to be exchanged with the external air at a relatively slow rate, preventing the accumulation of harmful substances and keeping the internal temperature of the device body 1 relatively low at all times, ensuring that the optical adhesive is in a relatively hardened state and preventing it from softening too much and affecting the processing.
