Description

Technical Field

[0001] This utility model relates to the field of optical adhesive technology, specifically to an OCA optical adhesive cleaning device. Background Technology

[0002] OCA optical adhesive is one of the important raw materials for touch screens. It is made by creating optical acrylic adhesive without a substrate, then bonding a release film to the top and bottom layers, and finally adding a base film. OCA optical adhesive is a double-sided adhesive tape without a substrate material, making it the best adhesive for touch screens. However, OCA optical adhesive is very easily deformed under pressure, and its cleanliness requirements are extremely high.

[0003] During the processing of optical adhesives, some dust and other particles remain on the cut optical adhesive. If not cleaned properly, it will affect the product quality. Some cleaning institutions now use a soft roller brush to directly remove particulate impurities. However, some fine dust with strong adhesion is difficult to remove. Fine dust adhering to the optical adhesive for a long time will affect the quality of the optical adhesive. Therefore, we propose the OCA optical adhesive cleaning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an OCA optical adhesive cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an OCA optical adhesive cleaning device, comprising a frame, four mounting plates fixedly connected to the top of the frame, a take-up roller rotatably disposed between the two mounting plates on the left side, and a feed roller rotatably disposed between the two mounting plates on the right side. The top of the frame has two recesses, and above the two recesses is a vertically movable adhesive removal mechanism for removing highly adhesive dust. To the right of the vertically movable adhesive removal mechanism is a dust suction mechanism for removing particulate impurities.

[0006] A further preferred embodiment of the movable adhesive removal mechanism includes two guide rods, which are fixedly connected to the top of the recess. Side ears are slidably connected to the outer side of the guide rods, and a round rod is fixedly connected between the two side ears. A rotating sleeve is rotatably connected to the outer side of the round rod, and multiple detachable adhesive layers are provided on the outer side of the rotating sleeve.

[0007] In a further preferred embodiment, a baffle is fixedly connected to the top of the guide rod, and a spring is fixedly connected between the side ear and the top inner wall of the recess, with the spring movably sleeved on the outside of the guide rod.

[0008] In a further preferred embodiment, the dust collection mechanism includes a U-shaped frame, which is fixedly connected to the frame. A dust collection box is fixedly connected to the bottom of the U-shaped frame, and a vacuum cleaner is connected to the bottom of the dust collection box. The suction port of the vacuum cleaner is connected to a cylinder, and the dust discharge port is connected to the dust collection box.

[0009] More preferably, a flow guide is provided on the side of the cylinder facing the wire feeding roller, and the flow guide is inclined downward.

[0010] More preferably, two limiting rollers are provided between the take-up roller and the pay-off roller, and the limiting rollers are rotatably connected to the frame via bearings.

[0011] More preferably, a motor is fixedly connected to the mounting plate on the left side, and the end of the motor's output shaft is fixedly connected to the take-up roller for driving the take-up roller to rotate and take up the wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the optical adhesive to be cleaned on the outside of the pay-off roller passes sequentially around two limiting rollers and is then fixed to the outside of the take-up roller. A dust-collecting mechanism sucks up large particles of impurities from the surface of the optical adhesive, followed by a removable adhesive mechanism that removes fine dust. A motor drives the take-up roller to rotate, thereby winding up the cleaned optical adhesive. The vacuum cleaner's suction port is connected to a cylinder, and a guide hood is installed on the right side of the cylinder at a downward angle to facilitate the removal of large particles of impurities from the surface of the optical adhesive during vacuum cleaner operation, thus collecting dust. The box facilitates the collection of impurities. The side lugs on both sides of the round rod are slidably connected to the guide rod, and a spring is installed between the bottom of the side lug and the recessed part. This allows the spring to provide a continuous downward clamping force on the round rod. It can also accommodate optical adhesives of different thicknesses. The dust on the surface of the optical adhesive can be removed by the detachable adhesive layer on the rotating sleeve connected to the outside of the round rod. After removal, the outermost detachable adhesive layer with dust adhering to it can be peeled off, making it easy to clean and collect the fine dust with strong adhesion on the surface of the optical adhesive. It is highly practical. Attached Figure Description
