Description

Technical Field

[0001] The present application relates to the field of optical sheet processing technology, and in particular to an optical sheet active agent spraying device. Background Art

[0002] Optical sheets refer to polarizers. Liquid crystal displays rely on polarized light for imaging. All LCDs have two polarizers, front and back, placed tightly against the LCD glass, creating a roughly 1mm thick sheet. During the manufacturing process, an activator is sprayed onto the surface of the polarizer to prevent sticking and static electricity from foreign matter.

[0003] Currently, operators usually spray the active agent onto the optical sheet through an atomizing nozzle. However, the active agent sprayed through the atomizing nozzle may have uneven thickness on the optical sheet, thereby affecting the normal use of the optical sheet. Summary of the Invention

[0004] In order to alleviate the problem of uneven spraying of active agent on optical sheets, the present application provides an optical sheet active agent spraying device.

[0005] The present application provides an optical sheet active agent spraying device that adopts the following technical solutions:

[0006] An optical sheet active agent spraying device includes a frame, to which are rotatably connected a plurality of rotating rollers for guiding the optical sheet, the frame is provided with a plurality of nozzles for spraying the active agent onto the optical sheet, the frame is fixedly connected to a cylinder, the piston rod of the cylinder is fixedly connected to a mounting frame, the mounting frame is detachably provided with a smear pad for evenly spreading the active agent on the optical sheet, and the cylinder is used to drive the mounting frame to move toward the optical sheet.

[0007] By adopting the above technical solution, the optical sheet is wound around several rotating rollers, and the operator sprays the active agent on one side of the optical sheet through a nozzle. At the same time, the operator starts the cylinder to move the mounting frame toward the optical sheet and places the smear pad against the optical sheet. During the movement of the optical sheet, the optical sheet sprayed with the active agent passes through the smear pad, and the excess active agent on the optical sheet is absorbed by the smear pad. The active agent on the optical sheet is evenly smeared through the relative movement between the smear pad and the optical sheet.

[0008] Optionally, a plurality of cross frames are fixedly connected to the frame, and a plurality of fans are fixedly connected to the cross frames, and the fans are used to dry the active agent on the optical sheet.

[0009] By adopting the above technical solution, when the optical sheet sprayed with the active agent passes through the cross bar, the fan dries the active agent on the optical sheet, thereby reducing the corrosion of the rotating roller behind by the active agent.

[0010] Optionally, a guide plate is hinged on the mounting frame, a clamping plate for pressing against the smear pad is provided on the guide plate, and a fixing component for fixing the guide plate is provided on the mounting frame.

[0011] By adopting the above technical solution, the smear pad is arranged between the splint and the mounting frame. The operator can control the distance between the splint and the mounting frame by flipping the guide plate. After the splint and the mounting frame clamp the smear pad, the operator fixes the guide plate to the mounting frame through the fixing component, so that the smear pad can be detachably connected to the mounting frame, which is convenient for the operator to replace the smear pad.

[0012] Optionally, the fixing assembly includes side plates fixedly connected to both sides of the mounting frame, a through hole is provided on the side plate, an outer cylinder is provided on the guide plate, an insertion rod for inserting into the through hole is slidably inserted into the outer cylinder, a spring is provided on the outer cylinder for pushing the insertion rod toward the through hole, and an inclined plate is provided on the side plate for guiding the insertion rod into the through hole.

[0013] By adopting the above technical solution, in the initial state, the guide plate flips down, causing the mounting frame and the clamping plate to move away from each other, facilitating the operator to install the applicator pad. The operator flips up the guide plate, causing the mounting frame and the clamping plate to move closer together until the guide plate abuts the two side plates, at which point the mounting frame and the clamping plate clamp the applicator pad. During the guide plate flipping process, the insertion rod abuts the inclined plate before the inclined plate. Under the guidance of the inclined plate, the insertion rod overcomes the elastic force of the spring and retracts into the outer tube. When the guide plate abuts the two side plates, the insertion rod aligns with the through hole. At this time, the insertion rod is inserted into the through hole under the elastic force of the spring, thereby fixing the position of the guide plate on the mounting frame and fixing the applicator pad between the mounting frame and the clamping plate.

[0014] Optionally, a sleeve is rotatably connected to the guide plate, the two outer cylinders are fixedly connected to the sleeve, and the two side plates are provided with arc grooves for the sliding of the insertion rod, the arc grooves are connected to the corresponding through holes, and the arc grooves are open at one end away from the through hole, and the guide plate is provided with a limiting unit for limiting the flipping of the sleeve and keeping the insertion rod inserted in the through hole.

[0015] By adopting the above technical solution, when the applicator pad needs to be replaced, the operator releases the limiting effect of the limiting unit on the sleeve, and then the operator flips the sleeve to drive the insertion rod to flip around the axis of the sleeve, and makes the insertion rod slide out of the arc groove, thereby releasing the limiting effect between the guide plate and the mounting frame, so that the operator can quickly remove the applicator pad.

[0016] Optionally, the limiting unit includes a first stop block and a second stop block on a fixed guide plate, a handle is fixedly connected to the sleeve for abutting the first stop block or the second stop block, a torsion spring is sleeved on the sleeve, and the torsion spring pushes the handle to abut the first stop block, and when the handle abuts the first stop block, the insertion rod tilts toward the through hole.

[0017] By adopting the above technical solution, the handle is arranged between the first stop block and the second stop block to limit the flipping angle of the sleeve. In the initial state, the torsion spring drives the insertion rod to tilt toward the through hole. When the operator needs to flip the guide plate and remove the applicator pad, the operator needs to overcome the elastic force of the torsion spring to flip the handle. The handle drives the sleeve to flip, so that the insertion rod slides out of the arc groove, releasing the limiting effect between the guide plate and the mounting frame, so that the operator can quickly remove the applicator pad.

[0018] Optionally, the splint is hinged to the guide plate via a flip rod, a push rod is provided on the flip rod, a tension spring is connected between the splint and the guide plate, and the tension spring pulls the splint and makes the push rod abut against the guide plate, and a push block for the push rod to abut is fixedly connected to the frame.

[0019] By adopting the above technical solution, the tension spring pulls the push rod to abut against the guide plate. When the cylinder drives the mounting frame and the splint to move downward, the push rod abuts against the push block. Under the blocking action of the push block, the push rod overcomes the elastic force of the tension spring and moves away from the guide plate, thereby driving the splint to move toward the flip frame and clamp the applicator pad, squeezing out excess active agent on the applicator pad.

[0020] Optionally, the frame is fixedly connected to a base, the base is hinged to a flip frame, the flip frame is hinged to a connecting rod, the connecting rod is hinged to a slide, the slide is slidably set on the base, the base is threaded with a stud, the stud is rotatably connected to the slide, the flip frame is hinged to a fixed plate, each of the nozzles is fixedly connected to the fixed plate, and the flip frame is provided with an adjustment unit for controlling the angle adjustment of the fixed plate.

[0021] By adopting the above technical solution, the operator drives the slide to move by rotating the stud, and then drives the flip frame to flip through the connecting rod to achieve height adjustment of the nozzle; the operator adjusts the angle of the fixed plate through the adjustment unit, and then adjusts the angle of each nozzle, which is beneficial to improve the spraying effect of the active agent on the optical sheet.

[0022] Optionally, the adjustment unit includes a worm rotatably connected to the fixed plate, the fixed plate is hinged to the flip frame via a rotating shaft, the rotating shaft is fixedly connected to the flip frame, a worm wheel is coaxially fixedly connected to the rotating shaft, and the worm and worm wheel are engaged with each other.

[0023] By adopting the above technical solution, the operator rotates the worm to make the worm wheel and the fixed plate rotate relative to each other. Since the worm wheel is fixedly connected to the flip frame, and the worm is rotatably connected to the fixed plate, when the worm rotates, the fixed plate flips on the flip frame, thereby realizing the angle adjustment of the nozzle.

[0024] Optionally, the side of the guide plate away from the mounting frame is always tilted downward, and a receiving tray for receiving the active agent is fixedly connected to the frame. The receiving tray is located below the nozzle and the guide plate. The receiving tray is tilted, and a drainage hole is provided at the lower end of the receiving tray.

[0025] By adopting the above technical solution, the guide plate is tilted so that excess active agent on the smear pad can fall onto the receiving tray through the guiding effect of the guide plate, and the receiving tray is tilted at one end with a drainage hole to facilitate the discharge of the active agent from the drainage hole for collection.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The cylinder is activated to move the mounting frame toward the optical sheet and abut against the optical sheet. During the movement of the optical sheet, the optical sheet sprayed with the active agent passes over the smear pad, which absorbs excess active agent on the optical sheet and evenly spreads the active agent on the optical sheet.

[0028] 2. When the cylinder drives the mounting frame and the clamping plate away from the optical sheet, the push rod abuts against the push block. Under the blocking effect of the push block, the push rod and the guide plate move away from each other, thereby driving the clamping plate to move toward the flip frame and clamp the smear pad, squeezing out the excess active agent on the smear pad so that the smear pad can continue to be used.

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The present application discloses an optical sheet active agent spraying device. Figure 1The optical sheet active agent spraying equipment includes a frame 1 set on the ground, and the frame 1 is in the shape of a rectangular frame. Two rotating rollers 11 are rotatably connected on both sides of the frame 1 along its width direction, and the two rotating rollers 11 located on the same side of the frame 1 are spaced apart along the height direction of the frame 1, and the axial direction of each rotating roller 11 is parallel to the length direction of the frame 1. The two rotating rollers 11 located on one side of the frame 1 are denoted as the first roller 12 and the second roller 13, and the first roller 12 is located below the second roller 13. The two rotating rollers 11 located on the other side of the frame 1 are denoted as the third roller 14 and the fourth roller 15, and the fourth roller 15 is located below the third roller 14. A reeling mechanism for reeling the optical sheet 18 is provided on one side of the frame 1, and a traction mechanism for traction of the optical sheet 18 is provided on the other side of the frame 1. After being unwound from the unwinding mechanism, the optical sheet 18 passes through the bottom of the first roller 12, then goes upward around the top of the second roller 13, and then around the top of the third roller 14. Then the optical sheet 18 extends toward the fourth roller 15 and goes around the bottom of the fourth roller 15. Finally, the optical sheet 18 enters the traction mechanism and moves toward the next process.

[0040] like Figure 1 and Figure 2 The frame 1 is fixedly connected to a rectangular frame-shaped base 2 below the first roller 12. The base 2 is arranged horizontally, and the width direction of the base 2 is parallel to the width direction of the frame 1. A turning frame 22 is hinged above the base 2 through a first hinge shaft 21, and the axis of the first hinge shaft 21 is parallel to the length direction of the frame 1. A connecting rod 24 is hinged on the turning frame 22 through a second hinge shaft 23. The end of the connecting rod 24 away from the turning frame 22 is hinged to a slide 26 through a third hinge shaft 25. The slide 26 is slidably arranged on the base 2, and the sliding direction of the slide 26 is parallel to the width direction of the base 2. The axes of the second hinge shaft 23 and the third hinge shaft 25 are both parallel to the axis of the first hinge shaft 21. A stud 27 is threadedly connected to the base 2, and the axial direction of the stud 27 is parallel to the width direction of the base 2. The stud 27 is rotatably connected to the slide 26.

[0041] like Figure 2 and Figure 3 The end of the flip frame 22 away from the base 2 is fixedly connected to a rotating shaft 3, with the axial direction of the rotating shaft 3 being parallel to the length of the base 2. A rectangular fixed plate 31 is rotatably connected to the rotating shaft 3, with the length of the fixed plate 31 being parallel to the length of the base 2. The fixed plate 31 is provided with an adjustment assembly 311 for adjusting the tilt angle between the fixed plate 31 and the flip frame 22. The adjustment assembly 311 includes a worm gear 32 fixedly connected coaxially to the rotating shaft 3. A worm 33 is rotatably connected to the side of the fixed plate 31 facing the worm gear 32, which meshes with the worm gear 32.

[0042] A plurality of nozzles 34 for spraying active agents on the optical sheet 18 are fixedly connected to the side of the fixed plate 31 facing away from the rotating shaft 3, and the plurality of nozzles 34 are evenly arranged along the length direction of the fixed plate 31. A cover plate 35 is fixedly connected to the boundary position of the fixed plate 31, and the cover plate 35 and the fixed plate 31 form a accommodating cavity 36, and each nozzle 34 is located in the accommodating cavity 36.

[0043] The operator first drives the slide 26 to move by rotating the stud 27. Under the push of the connecting rod 24, the flip frame 22 flips, thereby driving each nozzle 34 to achieve height adjustment; the operator drives the worm gear 32 and the fixed plate 31 to rotate relative to each other by twisting the worm 33, and then adjusts the angle of the fixed plate 31 to achieve angle adjustment of each nozzle 34. The operator improves the spraying effect of the active agent on the optical sheet 18 by adjusting the height and angle of each nozzle 34.

[0044] like Figure 2 and Figure 4 Two cylinders 4 are also vertically fixedly connected above the base 2. A rectangular plate-shaped mounting frame 41 is vertically fixedly connected between the piston rods of the two cylinders 4. The length of the mounting frame 41 is parallel to the length of the frame 1. Side panels 42 are fixedly connected to both sides of the mounting frame 41 along its length. A guide plate 44 is hingedly connected to the lower side wall of the mounting frame 41 via a fourth hinge axis 43. When the guide plate 44 is tilted to abut the two side panels 42, the side of the guide plate 44 away from the mounting frame 41 tilts downward. The guide plate 44 is provided with a fixing assembly 5 for fixed connection with the side panels 42. A rectangular plate-shaped clamping plate 45 is provided above the guide plate 44. The length of the clamping plate 45 is parallel to the length of the mounting frame 41. A plurality of tilting rods 451 are fixedly connected to the clamping plate 45. The plurality of tilting rods 451 are evenly arranged along the length of the clamping plate 45 and hingedly connected to the upper surface of the guide plate 44 via a fifth hinge axis.

[0045] like Figure 4 and Figure 5 A smear pad 46 is sandwiched between the clamping plate 45 and the mounting frame 41. A support plate 461 for supporting the smear pad 46 is fixedly connected to the side of the mounting frame 41 facing the clamping plate 45. The smear pad 46 is a sponge pad and is located directly below the first roller 12. Each flip rod 451 is fixedly connected to a push rod 47, and several push rods 47 are evenly arranged along the length of the clamping plate 45.

[0046] like Figure 4 and Figure 6 A tension spring 48 is fixedly connected between the splint 45 and the guide plate 44, and the tension spring 48 pulls the push rod 47 to abut against the guide plate 44. Several push rods 47 are fixedly connected by a connecting rod 49. A push block 491 is fixedly connected to the frame 1, and the push block 491 is located below the connecting rod 49.

[0047] When the piston rods of both cylinders 4 are extended, the applicator pad 46 abuts against the optical sheet 18, absorbing and evenly spreading excess active agent on the optical sheet 18. When the piston rods retract, they move the mounting frame 41, the clamping plate 45, and the applicator pad 46 away from the first roller 12. During this process, the push block 491 pushes the connecting rod 49, which drives the clamping plate 45 toward the mounting frame 41 and squeezes the applicator pad 46, squeezing out excess active agent.

[0048] like Figure 7 and Figure 8 The fixing assembly 5 includes a sleeve 51 rotatably connected to the bottom of the guide plate 44. The guide plate 44 is provided with a limiter 6 for limiting the rotation of the sleeve 51. The axial direction of the sleeve 51 is parallel to the length of the guide plate 44, and connecting plates 52 are fixedly connected to both ends of the sleeve 51. An outer cylinder 53 is fixedly connected to the connecting plate 52, and the axial direction of the outer cylinder 53 is parallel to the axial direction of the sleeve 51. The sleeve 51 corresponds to the side plate 42 one-to-one and is located on the side of the side plate 42 away from the clamping plate 45. A rod 54 is slidably inserted into the sleeve 51. The end of the insertion rod 54 away from the side plate 42 passes through the outer cylinder 53 and is fixedly connected to an end plate 55 for abutting the outer cylinder 53. The insertion rod 54 is fixedly connected to a push plate 56 on the side of the outer cylinder 53 facing the side plate 42, and a spring 57 is sleeved on the insertion rod 54 between the outer cylinder 53 and the push plate 56, and the spring 57 pushes the insertion rod 54 and makes the end plate 55 abut against the outer cylinder 53.

[0049] like Figure 5 and Figure 7 The side plate 42 is provided with a through-hole 58 for the insertion rod 54 to pass through. The side plate 42 also has an arcuate slot 59 that communicates with the through-hole 58. The arcuate slot 59 is open at the end away from the through-hole 58. A slanted plate 591 is fixedly connected to the bottom of the side plate 42, with the lower end of the slanted plate 591 tilted away from the corresponding outer cylinder 53. The slanted plate 591 guides the insertion rod 54 so that the insertion rod 54 can be directly inserted into the through-hole 58 when it moves toward the side plate 42. When the guide plate 44 is flipped to abut the side plate 42, the arcuate slot 59 and the sleeve 51 are coaxial, and the insertion rod 54 can slide within the arcuate slot 59.

[0050] The limiting unit 6 includes a first stopper 61 and a second stopper 62 fixedly connected to the lower surface of the guide plate 44. The sleeve 51 is positioned between the first stopper 61 and the second stopper 62, with the first stopper 61 being located on the side of the sleeve 51 away from the fourth hinge axis 43. A handle 63 is fixedly connected to the sleeve 51 and positioned between the first stopper 61 and the second stopper 62. A torsion spring 64 is sleeved on the sleeve 51. One end of the torsion spring 64 abuts the lower surface of the guide plate 44, and the other end of the torsion spring 64 is fixedly connected to the handle 63. The torsion spring 64 pushes the handle 63 into contact with the first stopper 61. When the guide plate 44 abuts the side plate 42, when the handle 63 abuts the first stopper 61, the sleeve 51 drives the two insertion rods 54 to be inserted into the through-holes 58. When the handle 63 abuts the second stopper 62, the sleeve 51 drives the two insertion rods 54 out of the corresponding through-holes 58 and arcuate slots 59.

[0051] In the initial state, the handle 63 abuts against the first stopper 61, and the guide plate 44 flips down and disengages from the two side plates 42. When the operator installs the applicator pad 46, the applicator pad 46 is placed on the support plate 461, and then the operator flips the guide plate 44 toward the two side plates 42. During this process, the insertion rod 54 first abuts against the inclined plate 591. Under the guidance of the inclined plate 591, the insertion rod 54 gradually moves toward the through hole 58. When the guide plate 44 abuts against the two side plates 42, the insertion rod 54 aligns with the corresponding through hole 58. Under the elastic force of the spring 57, the insertion rod 54 is inserted into the through hole 58, thereby fixing the position of the guide plate 44 on the two side plates 42. At this time, the applicator pad 46 is fixed between the mounting frame 41 and the clamping plate 45.

[0052] When the operator needs to quickly replace the applicator pad 46, the operator pushes the handle 63 to overcome the elastic force of the torsion spring 64 and flip it toward the second stop block 62, thereby driving the connecting plate 52 to flip around the sleeve 51, so that the insertion rod 54 gradually slides out of the through hole 58 and the arc groove 59, releasing the limiting effect between the side plate 42 and the guide plate 44, making it convenient for the operator to remove the original applicator pad 46 from the mounting bracket 41 and replace it with a new applicator pad 46.

[0053] like Figure 6 The frame 1 is fixedly connected to a receiving tray 65 below the base 2. The receiving tray 65 is located below the guide plate 44 and the fixed plate 31. The receiving tray 65 is tilted downward toward the side of the fourth roller 15, and a drainage hole 66 is provided on the lower side of the receiving tray 65 to collect the active agent received by the receiving tray 65.

[0054] A cross frame 16 is fixedly connected to the frame 1 between the first roller 12 and the second roller 13. The length direction of the cross frame 16 is parallel to the length direction of the frame 1. A plurality of fans 17 are fixedly connected to the frame 1, and the fans 17 are evenly arranged along the length direction of the cross frame 16. The fans 17 are used to dry the active agent on the optical sheet 18 between the first roller 12 and the second roller 13 to reduce the corrosion of the active agent on the rotating roller 11 behind.

[0055] The operating principle of the embodiment of the present application is as follows: As the optical sheet 18 enters the first roller 12 from the unwinding mechanism, each nozzle 34 first sprays the active agent toward the optical sheet 18. At the same time, the two cylinders 4 are activated to drive the applicator pad 46 toward the optical sheet 18 and abut against the optical sheet 18. The applicator pad 46 absorbs excess active agent from the optical sheet 18 and evenly spreads the active agent on the optical sheet 18. After a set period of use, the absorbent on the applicator pad 46 may become saturated. At this time, the operator pauses the transportation of the optical sheet 18 on the frame 1. The operator needs to activate the cylinder 4 to drive the mounting frame 41, the applicator pad 46, and the clamping plate 45 away from the optical sheet 18. During this process, the push block 491 pushes the connecting rod 49 and the push rod 47, causing the clamping plate 45 to move toward the mounting frame 41, thereby squeezing the applicator pad 46 and squeezing out excess active agent so that the applicator pad 46 can continue to be used.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
