Description

Technical Field

[0001] This utility model relates to the field of OCA optical adhesive production technology, and in particular to a winding device for OCA optical adhesive production. Background Technology

[0002] OCA (Optically Clear Adhesive) is one of the raw materials for processing touch screens. OCA optical adhesive is made by creating a substrate-free optical acrylic pressure-sensitive adhesive, and then applying an optical release film to both the top and bottom layers to create a double-sided laminating tape. It is a substrate-free double-sided laminating tape. In OCA optical adhesive production, factories typically produce and package OCA optical adhesive films in rolls. The OCA optical adhesive needs to be wound into rolls using a winding machine for later processing and use.

[0003] However, during the current OCA optical adhesive winding process, dust easily adheres to the surface of the OCA optical adhesive, affecting the product quality. Moreover, the excessive length of the OCA optical adhesive during winding can easily cause wrinkles.

[0004] Therefore, a rewinding device for OCA optical adhesive that facilitates cleaning and alignment is proposed. Utility Model Content

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] 1. In this utility model, the lifting plate is pushed by an electric push rod, causing the jet pipes to move downwards. This brings the nozzles between the jet pipes close to the outer surface of the OCA optical adhesive, allowing the jet pipes to blow air and clean the surface of the OCA optical adhesive as it is pulled. This prevents dust from adhering to the surface and affecting the quality of the OCA optical adhesive. Furthermore, the side fan blows the dust from the surface towards the suction end, and the suction fan draws the dust into the filter bag through the suction pipe on the outside of the dust hood. This prevents the dust from scattering after cleaning and affecting the subsequent cleaning of the OCA optical adhesive, making subsequent cleaning easier and improving the cleaning effect of the OCA optical adhesive.

[0023] 2. In this utility model, the limiting post is loosened by rotating the nut, allowing it to move left and right.

This results in better quality OCA optical adhesive during winding and reduces unnecessary losses.

[0024] 3. In this utility model, the first motor drives the lead screw, which causes the movable slider to move the movable plate, thereby separating the upper insertion slot from the insertion block and thus separating the take-up roller. Furthermore, when the lead screw moves, the distance between the fixed plate and the movable plate can be adjusted, allowing take-up rollers of different sizes to be wound, making it more practical and effective.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0034] Please see Figures 1-6 This utility model provides a winding device for the production of OCA optical adhesive, which consists of a cleaning mechanism, a limiting mechanism and a winding mechanism;

[0035] The cleaning mechanism includes an outer dust collection box 1, which reduces the entry or escape of external dust. A guide wheel 7 is rotatably connected to the outer opening of the dust collection box 1 via a fixed plate 6. The rotation of the guide wheel 7 facilitates the movement and conveying of the OCA optical adhesive at the upper end, preventing contact between the OCA optical adhesive and the dust collection box 1. A control panel 5 is installed on the outer side of the dust collection box 1 for operation. Openings on the front and rear sides of the dust collection box 1 allow the OCA optical adhesive to pass through during cleaning inside the dust collection box 1. A partition 13 is connected to the openings to form a cavity with the bottom of the dust collection box 1. The cavity has openings on both sides to facilitate operation of the internal equipment. A lifting plate 14 is located at the upper part of the dust collection box 1. Electric push rods 16 are symmetrically installed at the top of the dust collection box 1, with their output ends passing through the dust collection box 1 and connecting to the lifting plate 14. The electric push rods 16 push the lifting plate 14 up and down, avoiding manual rotation and increasing efficiency. The symmetrical connection of the electric push rods 16 also improves stability on both sides. Air jet pipes 15 are located at the corresponding positions of the lifting plate 14 and the partition 13, and several nozzles are located inside the air jet pipes 15, allowing the air jet pipes 15 to spray near the upper and lower ends of the OCA optical adhesive. Afterwards, it can be cleaned by air jets, so that the air blown by the air jet pipe 15 can reduce damage to the OCA optical adhesive. A dust collection box 18 is provided inside the cavity, and an opening is provided on the outside of the dust collection box 18 to remove and clean the internal filter bag 19. The filter bag 19 installed inside the dust collection box 18 collects dust, making cleaning more convenient. The bottom of the filter bag 19 is provided with a collection cover 110. A suction fan 111 is installed inside the dust collection box 18, and the suction end of the suction fan 111 is connected to the bottom of the collection cover 110. The output end of the suction fan 111 is connected to the air jet pipes 15 at the top and bottom through a three-way pipe, so that the suction fan 111 can... The upper and lower ends of the air supply end supply air to the jet pipe 15 to blow OCA optical adhesive. A fan 11 is installed on one side of the dust collection box 1, and a dust collection hood 12 is provided on the corresponding side of the dust collection box 1. The bottom end of the dust collection hood 12 passes through the suction pipe 17 through one side of the dust collection box 1. Under the action of the fan 11, the air inside the dust collection box 1 is blown by the fan 11, which makes the dust blown inside the dust collection box 1 more pleasing to the suction force generated by the suction fan 111. The dust blown inside the dust collection box 1 is then collected inside the dust collection box 18 through the dust collection hood 12 and the suction pipe 17. Moreover, both the collection hood 110 and the dust collection hood 12 are designed in the shape of a funnel to enhance the suction force and make the suction effect better.

[0036] The limiting mechanism includes an alignment frame 2 connected to the dust collection box 1. The alignment frame 2 is hollow inside, which restricts the movement of OCA optical adhesive within the alignment frame 2, enhancing the limiting effect. The top of the alignment frame 2 has a through top groove 21 that spans both sides, maximizing the length of the top groove 21 to accommodate different sizes of OCA optical adhesive. The bottom of the alignment frame 2 has a bottom groove 22, which facilitates the placement of the bottom end of the limiting post 24 inside the bottom groove 22, ensuring that the OCA optical adhesive contacts the side of the limiting post 24 when being wound up at different positions. The limiting posts 24 are symmetrically installed inside the bottom groove 22, and the top of the limiting post 24 is connected to a screw 27 that passes through the top groove 22. 1. The top of the screw 27 is connected to a nut 28. The nut 28 is used to fix and move the limiting post 24. After the limiting post 24 is adjusted to the limiting position of the OCA optical adhesive, the nut 28 can be turned to fix it, preventing the limiting post 24 from wobbling left and right. This makes the limiting post 24 more effective in preventing the OCA optical adhesive from shifting. The bottom of the alignment frame 2 is arc-shaped, which reduces damage to the OCA optical adhesive when it slides at the bottom of the alignment frame 2, and makes the pulling effect better. The bottom groove 22 has a through groove 23 at the bottom end. The bottom end of the limiting post 24 is connected to a connecting rod 25 that passes through the through groove 23. The bottom end of the connecting rod 25 is connected to a limiting plate 26. This prevents the limiting post 24 from being pulled upward under the action of the limiting plate 26 and increases the stability of the limiting post 24.

[0037] The winding mechanism includes a base plate 3 connected to the bottom of the dust collector 1, which increases the overall stability. A fixed plate 4 and a movable plate 41 are connected to the upper end of the base plate 3. The fixed plate 4 fixes one end of the winding roller 46, while the movable plate 41 can be adjusted according to the size of the winding roller 46. The upper inner side of the fixed plate 4 and the movable plate 41 is provided with a rotating groove 42. A rotating ring 43 is connected to the inside of the rotating groove 42 through a bearing, and the winding roller 46 is connected between the rotating rings 43. Insertion blocks 47 are connected to both sides of the winding roller 46. An insertion groove 44 is provided on the inner side of the rotating ring 43 and is connected to the insertion block 47. Both the insertion groove 44 and the insertion block 47 are rectangular, which increases the force-bearing area and facilitates rotation. A second motor 45 is installed on the outer side of the fixed plate 4, and the output end of the second motor 45 passes through the rotating groove 42 and is connected to the rotating ring 43. When the second motor 45 drives the rotating ring 43 to work, it can realize the rotation of the winding roller 46, thereby achieving the winding effect, avoiding manual rotation and winding, and making the work efficiency higher.

[0038] Preferably, the base plate 3 has a movable cavity 31 inside, and a lead screw 32 is connected to the middle of the movable cavity 31 through a bearing. A first motor 33 is installed on the outside of the base plate 3, and the output end of the first motor 33 is connected to one side of the lead screw 32. A movable slider 34 is installed inside the movable cavity 31, and a threaded hole 35 is provided in the middle of the movable slider 34 to connect with the lead screw 32. The bottom end of the movable plate 41 is connected to the movable slider 34. When the first motor 33 drives the lead screw 32 to rotate, the movable slider 34 is moved through the threaded hole 35. In this way, the movable slider 34 drives the upper movable plate 41 to move left and right, thereby realizing the adjustment of the distance of the movable plate 41, so that different sizes of take-up rollers 46 can be fixed. Positioning rods 36 are connected to both sides of the movable cavity 31, and positioning holes 37 are provided on both sides of the movable slider 34 to connect with the positioning rods 36. With the sliding connection between the positioning rods 36 and the positioning holes 37, the stability of the movable slider 34 is stronger, avoiding the problem of left and right swaying affecting the winding effect.

[0039] Working principle: In use, first connect the fan 11, electric push rod 16, suction fan 111, first motor 33, second motor 45, and control panel 5 to an external power source. Then, pass the OCA optical adhesive through the dust collection box 1 and the alignment frame 2. Simultaneously, according to the length of the take-up roller 46, start the first motor 33 to adjust the position of the moving plate 41 so that the insertion block 47 at one end of the take-up roller 46 is inserted into the insertion slot 44 at the upper end of the fixed plate 4. Then, move the moving plate 41 so that the other end is also inserted into the corresponding insertion slot 44, thereby placing the take-up roller 46. After one end of the OCA optical adhesive is connected to the take-up roller 46, the electric push rod 16 pushes the lifting plate 14 to bring the air jet pipe 15 closer to the OCA optical adhesive, making it easier for the air outlet of the suction fan 111 to blow air. Both the fan 11 and the suction fan 111 are working. At the same time, the position of the limiting post 24 can be moved by turning the nut 28 so that it contacts the side of the OCA optical adhesive. Then, when the second motor 45 drives the take-up roller 46 to take up the adhesive, the air jet pipe 15 blows air to clean the surface of the OCA optical adhesive, while the fan 11 and the suction fan 111 collect the cleaned dust, thus completing the work.
