Description

Technical Field

[0001] The invention relates to the technical field of plastic material forming, in particular to a homogenizing coating component in a diffusion plate production process and an operating method thereof. Background Art

[0002] The diffuser is a material that interferes with light. Its main function is to fully scatter the incident light to achieve a softer and more uniform illumination effect. It is widely used in liquid crystal display, LED lighting, imaging display systems and other fields.

[0003] The main purpose of diffusion plate coating is to form a uniform coating on the surface of the diffusion plate. This coating can change the optical properties of the diffusion plate. The reflection, refraction and scattering of light can be controlled by adjusting the composition and thickness of the coating. The number of discharge pipes on the homogenization coating assembly is mostly fixed, and the coating liquid is discharged through the discharge pipes. Facing a wider diffusion plate, the distribution of the coating liquid in the width direction is easily unbalanced. The diffusion plate is wide and the number of discharge pipes is too small. After the coating liquid flows out from the limited discharge pipes, in the process of diffusing to both sides, the coating liquid in the area far away from the discharge pipe is not replenished in time, which will cause the coating amount in the edge part to be less than that in the center area. This uneven coating will cause differences in the optical properties of different areas of the diffusion plate and affect product quality. Summary of the invention

[0004] The object of the present invention is to provide a uniform coating assembly and an operating method thereof in a diffusion plate production process, so as to solve the problems raised in the above background technology.

[0007] Preferably, the shapes of the second side insert frame and the proximal side of the first side insert frame are engaged with each other, and the proximal side of the second side insert frame and the first side insert frame form a rectangular structure that blocks the liquid outlet pipe.

[0008] Preferably, a rectangular fixed frame is provided above the driving roller located on one side of the unloading end, and U-shaped buckles are provided on both sides of the rectangular fixed frame. The U-shaped buckles are fixedly installed on the fixing seats at corresponding positions, and a fixing plug is movably installed on the U-shaped buckles. An inserted scraper is movably inserted in the rectangular fixed frame, and the part of the fixing plug located in the rectangular fixed frame passes through the inserted scraper.

[0009] Preferably, a transverse connecting plate is provided between the plurality of the fixing seats and the lifting seats located above for connection, an electric push rod is fixedly installed in the side mounting frame, and a piston rod of the electric push rod is fixedly installed at the bottom of the transverse connecting plate.

[0010] Preferably, a liquid receiving groove is provided at the bottom of the inner wall of the main mounting frame.

[0011] Preferably, side fixing seats are fixedly installed on both sides of the inner wall of the main mounting frame, the side fixing seats are located on one side of the transmission roller at the center position, a plurality of telescopic rods are fixedly installed on the top of the side fixing seats, a rectangular bottom plate is fixedly installed on the telescopic rods, a buffer plate is fixedly installed on the top of the rectangular bottom plate, a rectangular top plate is fixedly installed on the top of the buffer plate, a stepper motor is fixedly installed on the top of the side fixing seat through a bracket, and a cam fixedly installed on the output shaft of the stepper motor is supported at a corresponding position at the bottom of the rectangular bottom plate.

[0012] Preferably, a wiping roller is arranged above the driving roller at the center position, a liquid-blocking ring is arranged outside the wiping roller, the liquid-blocking ring is fixedly installed on both sides of the inner wall of the main mounting frame, a plurality of rectangular fixing seats are fixedly installed at both ends of the outer wall of the wiping roller, a rotating rod is rotatably connected in the rectangular fixing seat, an inclined wiping plate is fixedly installed on the rotating rod, a back-supporting plate is fixedly installed on the back of the inclined wiping plate, an inclined supporting plate is fixedly installed on the outer wall of the wiping roller, and the top end of the inclined supporting plate is fixedly installed in the back-supporting plate.

[0013] Preferably, a liquid separation strip is fixedly mounted on the top of the liquid retaining ring, and a plurality of conical liquid separation heads are fixedly mounted on the liquid separation strip, and the positions of the conical liquid separation heads and the ports of the liquid outlet pipes correspond to each other.

[0014] The operating method of the homogenizing coating component includes the following steps: the first step: driving multiple horizontal connecting plates to rise and fall through the piston rod of the electric push rod, thereby driving multiple fixed seats and lifting seats to rise and fall, changing the distance between the two transmission rollers, the distance between the transmission roller and the wiping roller, and the distance between the rectangular fixed frame and the transmission roller to adapt to the coating operation of diffusion plates of different thicknesses.

[0015] Step 2: The coating liquid contacts with the liquid separation strip and the conical liquid separation head during the falling process. The collision between the two assists the dispersion of the coating liquid. The coating liquid falls on the oblique wiping plate outside the wiping roller and contacts with the diffusion plate. The coating liquid on multiple oblique wiping plates can contact with the diffusion plate to improve the coating effect on the diffusion plate.

[0016] Step 3: After passing through the diffusion plate between the transmission roller and the wiping roller, it reaches the top of the rectangular top plate. The output shaft of the stepper motor drives the cam to rotate, driving the lifting and lowering of the structure consisting of the rectangular bottom plate, the buffer plate and the rectangular top plate, thereby realizing the vibration of the diffusion plate and ensuring the uniform coating of the coating liquid on the diffusion plate.

[0017] Step 4: When passing between the driving roller and the rectangular fixed frame, the inserted scraper in the rectangular fixed frame scrapes off the excess coating liquid on the diffusion plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. According to the width of the diffusion plate, push the inserted pressure rod, and the end of the inserted pressure rod applies pressure to the outer side of the second side plug-in frame and the first side plug-in frame, so that the second side plug-in frame and the first side plug-in frame are compressed into the liquid outlet pipe to block the liquid outlet pipe. The inclined support plate supports the back support plate and the inclined wiping plate. The inclined support plate can be deformed to prevent the diffusion plate from being over-pressed. The coating liquid on multiple inclined wiping plates can contact the diffusion plate to improve the coating effect on the diffusion plate. When the appropriate number of discharge pipes is selected according to the width of the diffusion plate, the distribution of the coating material can be more accurately controlled. On a wider diffusion plate, if there is only one discharge pipe, the coating material flows from the center to both sides. During the process, factors such as distance and pressure may cause the coating amount on both sides to be less than that in the middle, resulting in uneven coating. Using a corresponding number of discharge tubes can simultaneously coat different areas of the diffuser plate, making the distribution of the coating material in the width direction more uniform, thereby ensuring the consistency of the optical performance of the diffuser plate. Taking the coating of diffuser plates on the production line as an example, a single discharge tube requires a long time to complete the coating of a diffuser plate, while multiple discharge tubes can cover the entire diffuser plate surface in a shorter time. For companies that produce diffuser plates on a large scale, this can effectively improve production efficiency, reduce production costs, and meet the market's large demand for products.

[0019] 2. The output shaft of the stepper motor drives the cam to rotate at intervals to apply upward thrust to the rectangular bottom plate. The rectangular top plate can vibrate relative to the rectangular bottom plate through the buffer plate, thereby realizing the vibration of the diffusion plate to ensure that the coating liquid is evenly applied on the diffusion plate. The vibrating diffusion plate can cause the coating liquid to flow on its surface. The coating liquid usually has a certain viscosity and may accumulate locally or flow poorly in a static state. When the diffusion plate vibrates, it is like applying an external force to the coating liquid, allowing it to flow better on the surface of the diffusion plate. The vibrating diffusion plate can cause the coating liquid to spread evenly over the entire surface, avoiding agglomeration caused by the viscosity of the coating liquid itself.

[0020] 3. Change the distance between the two transmission rollers, the distance between the transmission roller and the wiping roller, and the distance between the rectangular fixed frame and the transmission roller to adapt to the coating operation of diffusion plates of different thicknesses. Equipment that can handle diffusion plates of various thicknesses reduces the company's demand for purchasing special equipment for specific thicknesses. General-purpose equipment can be used for the production of various thicknesses, greatly reducing the cost of equipment purchase and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 14The present invention provides a technical solution: a homogenizing coating component in the production process of a diffusion plate, comprising a main mounting frame 1, side mounting frames 2 are fixedly installed on both sides of the main mounting frame 1, and the side mounting frames 2 are used to install additional components. Three sets of fixing seats 3 are arranged on the main mounting frame 1, and the positions of the fixing seats 3 and the transmission rollers 5 correspond to each other. The shafts of the transmission rollers 5 are fixed by the fixing seats 3. A lifting seat 4 is movably installed on the side mounting frame 2, and a component for driving the lifting is installed on the lifting seat 4. The lifting and lowering of the lifting seat 4 drives the lifting and lowering of the fixing seat 3 located above, thereby changing the distance between the transmission rollers 5, and realizing the processing of diffusion plates of different thicknesses. The lifting seat 4 and the fixing seat 3 located above are relative to each other. A transmission roller 5 is arranged between the fixed seats 3, and there are three groups of transmission rollers 5. The three groups of transmission rollers 5 are respectively located on the feeding side, the unloading side and the middle position. The shafts at both ends of the transmission roller 5 are located in the fixed seat 3. A liquid outlet bin 6 is fixedly installed at the center position of the top of the structure composed of the main mounting frame 1 and the side mounting frame 2. The coating material is placed in the liquid outlet bin 6. A liquid outlet control component 7 is fixedly installed at the bottom of the liquid outlet bin 6. A liquid outlet pipe 8 for driving the coating liquid to flow is arranged in the liquid outlet control component 7. A plurality of liquid outlet pipes 8 are arranged in the liquid outlet control component 7. The plurality of liquid outlet pipes 8 correspond to the discharge of the coating liquid. The liquid outlet pipe 8 is connected to the liquid outlet bin 6. The first side plug-in frame 9 and the first side plug-in frame 9 are movably installed at the bottom of the liquid outlet pipe 8. Two side plug-in frames 10, the first side plug-in frame 9 and the second side plug-in frame 10 are installed horizontally, and the sealing of the liquid outlet pipe 8 is realized by the mutual proximity of the first side plug-in frame 9 and the second side plug-in frame 10. A vertical fixing plate 11 is fixedly installed on the notches corresponding to the first side plug-in frame 9 and the second side plug-in frame 10 in the liquid outlet pipe 8. The vertical fixing plate 11 limits the movement of the first side plug-in frame 9 and the second side plug-in frame 10. The vertical fixing plate 11 is movably installed in the grooves provided on the first side plug-in frame 9 and the second side plug-in frame 10. A transverse spring 12 located in the first side plug-in frame 9 and the second side plug-in frame 10 is fixedly installed on the vertical fixing plate 11. The transverse spring 12 is fixedly installed on the vertical fixing plate 1 1, the transverse spring 12 can be deformed, and the transverse spring 12 generates a reverse elastic force on the first side plug-in frame 9 and the second side plug-in frame 10 to move, which is used for resetting the first side plug-in frame 9 and the second side plug-in frame 10. A fixing buckle 13 is fixedly installed at the bottom of the liquid outlet bin 6, and an inserted pressure rod 14 is movably inserted in the fixing buckle 13. The moving stroke of the inserted pressure rod 14 is limited by the fixing buckle 13. One end of the inserted pressure rod 14 corresponding to the second side plug-in frame 10 and the first side plug-in frame 9 is triangular. Through the triangular design, pressure is applied to the second side plug-in frame 10 and the first side plug-in frame 9, and the first side plug-in frame 9 and the second side plug-in frame 10 are pushed to retract into the liquid outlet pipe 8.

[0038] Side liquid baffles 15 are provided at positions corresponding to the front and back of the bottom of the liquid outlet bin 6 , and the side liquid baffles 15 block the coating liquid sprayed from the liquid outlet pipe 8 to prevent the coating liquid from splashing out.

[0039] The second side insert frame 10 and the first side insert frame 9 are engaged with each other, and the second side insert frame 10 and the first side insert frame 9 form a rectangular structure that blocks the liquid outlet pipe 8, ensuring that the inserted pressure rod 14 can completely press the first side insert frame 9 and the second side insert frame 10 into the liquid outlet pipe 8 during the extension of the inserted pressure rod 14.

[0040] A rectangular fixed frame 16 is arranged above the driving roller 5 on one side of the unloading end, and U-shaped buckles 17 are arranged on both sides of the rectangular fixed frame 16. The U-shaped buckle 17 is fixedly installed on the fixing seat 3 at the corresponding position, and a fixed plug 18 is movably installed on the U-shaped buckle 17. An inserted scraper 19 is movably inserted in the rectangular fixed frame 16, and the part of the fixed plug 18 located in the rectangular fixed frame 16 passes through the inserted scraper 19. The inserted scraper 19 is movably installed in the rectangular fixed frame 16 and is fixed by the installation of the fixed plug 18. The inserted scraper 19 is arranged above the driving roller 5 on the unloading side, and the excess coating liquid on the diffusion plate is scraped off by the cooperation of the inserted scraper 19 and the driving roller 5.

[0041] A transverse connecting plate 20 is arranged between the multiple fixed seats 3 and the lifting seats 4 located above for connection. An electric push rod 21 is fixedly installed in the side mounting frame 2. The piston rod of the electric push rod 21 is fixedly installed at the bottom of the transverse connecting plate 20. The piston rod of the electric push rod 21 drives the transverse connecting plate 20 to rise and fall, thereby driving the fixed seats 3 and the lifting seats 4 to rise and fall. When the fixed seats 3 and the lifting seats 4 are raised and lowered, the corresponding structures are driven to rise and fall to adapt to the coating operation of diffusion plates of different thicknesses.

[0042] A liquid receiving groove 101 is provided at the bottom of the inner wall of the main mounting frame 1 to receive and collect excess coating liquid.

[0043] Side fixing seats 22 are fixedly installed on both sides of the inner wall of the main mounting frame 1. The side fixing seats 22 are located on one side of the driving roller 5 at the center position. A plurality of telescopic rods 23 are fixedly installed on the top of the side fixing seats 22. A rectangular bottom plate 24 is fixedly installed on the telescopic rods 23. A buffer plate 25 is fixedly installed on the top of the rectangular bottom plate 24. A rectangular top plate 26 is fixedly installed on the top of the buffer plate 25. A stepper motor 27 is fixedly installed on the top of the side fixing seat 22 through a bracket. A cam fixedly installed on the output shaft of the stepper motor 27 is supported at a corresponding position at the bottom of the rectangular bottom plate 24. The cam is driven to rotate by the output shaft of the stepper motor 27, driving the rectangular bottom plate 24, the buffer plate 25 and the rectangular top plate 26 to make a small rise and fall. When the rectangular bottom plate 24, the buffer plate 25 and the rectangular top plate 26 are lifted and lowered, the diffusion plate is driven to vibrate slightly, so that the coating liquid on the surface of the diffusion plate is vibrated evenly.

[0044] A wiping roller 28 is arranged above the driving roller 5 at the center position, and a liquid blocking ring 29 is arranged outside the wiping roller 28. The liquid blocking ring 29 is fixedly installed on both sides of the inner wall of the main mounting frame 1, and a plurality of rectangular fixing seats 30 are fixedly installed at both ends of the outer wall of the wiping roller 28. A rotating rod 31 is rotatably connected in the rectangular fixing seat 30, and an inclined wiping plate 32 is fixedly installed on the rotating rod 31. A back-supporting plate 33 is fixedly installed on the back of the inclined wiping plate 32. An inclined supporting plate 34 is fixedly installed on the outer wall of the wiping roller 28, and the top end of the inclined supporting plate 34 is fixedly installed in the back-supporting plate 33. The inclined supporting plate 34 is made of a deformable material. Through the existence of the inclined wiping plate 32, the inclined wiping plate 32 applies pressure to the coating liquid on the diffusion plate, and the coating liquid is evenly smeared on the diffusion plate.

[0045] A liquid separator strip 35 is fixedly installed on the top of the liquid retaining ring 29 , and a plurality of conical liquid separator heads 36 are fixedly installed on the liquid separator strip 35 . The conical liquid separator heads 36 correspond to the positions of the ports of the liquid outlet pipe 8 . The conical liquid separator heads 36 receive and disperse the diffusion liquid sprayed from the liquid outlet pipe 8 to ensure that the diffusion liquid falls on the inclined wiping plate 32 .

[0046] Working principle: Step 1: The piston rod of the electric push rod 21 drives multiple horizontal connecting plates 20 to rise and fall, thereby driving multiple fixed seats 3 and lifting seats 4 to rise and fall, changing the distance between the two transmission rollers 5, the distance between the transmission roller 5 and the wiping roller 28, and the distance between the rectangular fixed frame 16 and the transmission roller 5 to adapt to the coating operation of diffusion plates of different thicknesses.

[0047] Step 2: During the falling process, the coating liquid contacts with the liquid separator strip 35 and the conical liquid separator head 36. The collision between the two assists the dispersion of the coating liquid. The coating liquid falls on the oblique wiping plate 32 outside the wiping roller 28 and contacts with the diffusion plate. The coating liquid on multiple oblique wiping plates 32 can contact with the diffusion plate to improve the coating effect on the diffusion plate.

[0048] Step 3: After passing through the diffusion plate between the driving roller 5 and the wiping roller 28, it reaches the top of the rectangular top plate 26. The output shaft of the stepping motor 27 drives the cam to rotate, driving the lifting and lowering of the structure composed of the rectangular bottom plate 24, the buffer plate 25 and the rectangular top plate 26, thereby realizing the vibration of the diffusion plate and ensuring the uniform coating of the coating liquid on the diffusion plate.

[0049] Step 4: When passing between the driving roller 5 and the rectangular fixed frame 16, the inserted scraper 19 in the rectangular fixed frame 16 scrapes off the excess coating liquid on the diffusion plate.

[0050] Working principle: Step 1: The piston rod of the electric push rod 21 drives multiple horizontal connecting plates 20 to rise and fall, thereby driving multiple fixed seats 3 and lifting seats 4 to rise and fall, changing the distance between the two transmission rollers 5, the distance between the transmission roller 5 and the wiping roller 28, and the distance between the rectangular fixed frame 16 and the transmission roller 5 to adapt to the coating operation of diffusion plates of different thicknesses.

[0051] Step 2: The diffusion plate is located between the two driving rollers 5 for conveying. According to the width of the diffusion plate, the liquid outlet pipe 8 for discharging the diffusion liquid is required to push the inserted pressure rod 14. The end of the inserted pressure rod 14 applies pressure to the outer side of the second side insertion frame 10 and the first side insertion frame 9. The second side insertion frame 10 and the first side insertion frame 9 are compressed and inserted into the liquid outlet pipe 8. At the same time, the transverse spring 12 is also compressed and deformed. The second side insertion frame 10 and the first side insertion frame 9 form a structure to block the liquid outlet pipe 8. The liquid outlet pipes 8 on both sides are blocked in turn, and the corresponding liquid outlet pipes 8 can discharge the coating liquid. During the falling process, the coating liquid contacts with the liquid separator strip 35 and the conical liquid separator head 36, and the collision between the two assists in the dispersion of the coating liquid, and the coating liquid falls on the inclined wiping plate 32 outside the wiping roller 28. The rotation of the wiping roller 28 drives the inclined wiping plate 32 to rotate, and the inclined wiping plate 32 contacts the diffusion plate. The inclined support plate 34 supports the back support plate 33 and the inclined wiping plate 32 to ensure the stability of the inclined wiping plate 32. At the same time, the inclined support plate 34 can be deformed to prevent the diffusion plate from being overly pressurized. The coating liquids on multiple inclined wiping plates 32 can contact the diffusion plate to improve the coating effect on the diffusion plate.

[0052] Step 3: After passing through the diffusion plate between the driving roller 5 and the wiping roller 28, it reaches the top of the rectangular top plate 26, and the output shaft of the stepping motor 27 drives the cam to rotate, thereby applying an upward thrust to the rectangular bottom plate 24 at intervals, driving the lifting and lowering of the structure composed of the rectangular bottom plate 24, the buffer plate 25 and the rectangular top plate 26. When the rectangular bottom plate 24, the buffer plate 25 and the rectangular top plate 26 are lifted and lowered, the telescopic rod 23 assists in guiding, and the rectangular top plate 26 can vibrate relative to the rectangular bottom plate 24 through the buffer plate 25, thereby realizing the vibration of the diffusion plate, ensuring that the coating liquid is evenly applied on the diffusion plate.

[0053] Step 4: When passing between the driving roller 5 and the rectangular fixed frame 16, the inserted scraper 19 in the rectangular fixed frame 16 scrapes off the excess coating liquid on the diffusion plate.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
