Description

Technical Field

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

[0002] Optical adhesives are specialty adhesives with high light transmittance and high bonding strength, widely used in the lamination and bonding of electronic devices such as touch screens, LCDs, and OLEDs. Their core characteristics include high transparency, low haze, weather resistance, UV resistance, and anti-yellowing properties, ensuring the clarity and durability of display devices. The production of optical adhesives mainly involves key processes such as raw material preparation, mixing, degassing, coating, or die-cutting. Common types include liquid and solid optical adhesives. Liquid adhesives require UV light or heat curing, while solid adhesive films are directly bonded after precision die-cutting.

[0003] A search revealed a patent with publication number CN220239497U, which discloses a dust removal device for optical adhesive production. This device sequentially feeds sheets of optical adhesive into the machine body via a feeding conveyor. A dust removal suction table within the machine body removes dust from the bottom of the optical adhesive, while a blowing and suction assembly at the top of the machine body removes dust from the top. After dust removal, the optical adhesive is conveyed out via a discharge conveyor, facilitating dust removal operations for personnel. However, this device has the following drawbacks: When the device blows air for dust removal, the fine particles are statically charged, causing dust to adhere firmly to the surface of the optical adhesive. Even after the dust is blown away, the statically charged dust may still fall onto other optical adhesive surfaces, resulting in poor dust removal efficiency. Increasing the blowing force can cause the optical adhesive to shift, affecting its stability. Furthermore, when the optical adhesive passes over the dust removal suction table, the strong negative pressure can adhere it to the suction table surface, making it difficult for the optical adhesive to move with the conveyor. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust removal device for optical adhesive production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for optical adhesive production, comprising a frame, a conveyor belt installed inside the frame, a top cover fixed to the top of the frame, and an inlet and an outlet respectively opened at the bottom of both ends of the top cover, a plurality of ion air bars horizontally arranged inside the top cover, and an adjustment component for driving the ion air bars to rise and fall installed on the top wall of the top cover, a suction hood fixed to the side wall of the top cover away from the inlet and outlet, a vacuum cleaner installed on the lower surface of the frame, a plurality of tray assemblies placed on the surface of the conveyor belt, and a controller installed on the outer side wall of the top cover.

[0006] Furthermore, a motor for driving the conveyor belt to rotate is installed on the outer wall of the frame.

[0007] Furthermore, the adjustment assembly includes a screw that penetrates the top wall of the top cover and is rotatably connected to the top cover via a thread. An internally threaded tube is rotatably connected to the bottom surface of the screw via a thread. A horizontal plate is fixed to the bottom end of the internally threaded tube.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a dust removal device for optical adhesive production is disclosed, comprising a frame 1, a conveyor belt 2 installed inside the frame 1, a top cover 3 fixed to the top of the frame 1, and an inlet 31 and an outlet 32 ​​respectively opened at the bottom of both ends of the top cover 3. Multiple ion air bars 4 are horizontally arranged inside the top cover 3, and an adjustment component 5 for driving the ion air bars 4 to rise and fall is installed on the top wall of the top cover 3.

[0025] The adjustment component 5 includes a screw 52 that penetrates the top wall of the top cover 3 and is rotatably connected to the top cover 3 by a thread. An internal threaded tube 53 is rotatably connected to the bottom surface of the screw 52 by a thread. A horizontal plate 51 is fixed to the bottom end of the internal threaded tube 53. A guide tube 55 is fixed on both sides of the upper surface of the horizontal plate 51. A guide rod 54 is slidably connected inside the guide tube 55. The top end of the guide rod 54 is fixedly connected to the inner top wall of the top cover 3. Multiple ion wind bars 4 are fixed to the lower surface of the horizontal plate 51.

[0026] In this embodiment, a knob is fixedly connected to the top of the screw 52. The screw 52 can be rotated by the knob, and the screw 52 drives the internal thread tube 53 to move along its surface. The internal thread tube 53 then drives the horizontal plate 51 to move up and down. The guide rod 54 and the guide tube 55 play a stabilizing guiding role in the movement of the horizontal plate 51. In this way, the horizontal plate 51 and the ion fan bar 4 can be adjusted by rotating the knob at the top of the screw 52 in the forward or reverse direction, so that the ion fan bar 4 can remove dust from the optical adhesive at a suitable height.

[0027] The tray assembly 8 includes a tray body 81, with a plurality of placement slots 82 for placing sheet-like optical adhesive on the upper surface of the tray body 81, and handles 83 fixed on both sides of the upper surface of the tray body 81.

[0028] In use, the optical adhesive can be placed in the placement slot 82 to increase the stability of the optical adhesive placement. Then, the tray 81 containing the optical adhesive is placed on the surface of the conveyor belt 2 for dust removal.

[0029] A slot 84 is provided on the lower surface of the disc body 81. A magnet 85 is fixedly connected to the top wall of the slot 84. Several locking blocks 21 are fixed at equal intervals on the surface of the conveyor belt 2. The locking blocks 21 are locked inside the slot 84 and are made of iron.

[0030] When the disc 81 is placed on the surface of the conveyor belt 2, the locking block 21 on the surface of the conveyor belt 2 is engaged in the slot 84, and the placement of the locking block 21 is increased by the attraction of the magnet 85.

[0031] A transparent viewing window is fixed to the side of the top cover 3 facing the suction cover 6. The height of the ion fan bar 4 can be adjusted through the viewing window, as well as the dust removal effect.

[0032] The vacuum cleaner 7's suction pipe is fixedly connected to the suction hood 6.

[0033] After connecting the vacuum cleaner 7 and the suction hood 6, the suction hood 6 can be used to extract and collect the blown dust.

The controller controls the coordinated operation of the motor, the vacuum cleaner 7, and the ion bar 4.

[0035] Working principle: Before use, adjust the height of the horizontal plate 51 and multiple ion bars 4 using the adjustment component 5. After adjustment, start the motor to drive the conveyor belt 2 to rotate slowly, and start the ion bars 4 and the vacuum cleaner 7. Then, place the optical adhesive that needs to be dusted into the placement groove 82 on the surface of each disc 81, and then place the disc 81 containing the optical adhesive on the surface of the conveyor belt 2. The conveyor belt 2 transports the disc 81 to the top cover 3. The ion bars 4 blow out ionized air to blow away the dust on the surface of the optical adhesive. The blown-away non-static dust is sucked away by the suction hood 6. The dust-removed optical adhesive is discharged from the discharge port 32 along with the disc 81. The worker can then remove the disc 81.
