Description

Technical Field

[0001] This utility model belongs to the field of conductive film processing technology, and in particular relates to a laser removal device for local conductive layer on the surface of a conductive film. Background Technology

[0002] Conductive thin films are thin film materials with conductive properties. The substrate is mostly polyester film, which has the characteristics of insulation, heat resistance and high elasticity. This material is widely used in antistatic films, thin film keyboard circuits, touch screen sensors and solar cell electrodes.

[0003] Currently available processing technologies have poor dust adsorption effects, relying solely on exhaust devices to adsorb dust on conductive films. This approach is ineffective at adsorbing highly adhesive dust, which can easily lead to reduced processing quality of conductive films.

[0004] To address this issue, we propose a laser removal device for localized conductive layers on the surface of conductive films. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the dust on the conductive film is simply adsorbed by a single exhaust device, which is not effective for adsorbing dust with strong adhesion and easily leads to a reduction in the processing quality of the conductive film. Therefore, this invention proposes a laser removal device for local conductive layer on the surface of conductive film.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser removal device for localized conductive layer on the surface of a conductive film includes a base plate. A protective cover, two drive motors, and four support plates are fixedly connected to the upper surface of the base plate. A laser galvanometer and two suction hoods are fixedly connected to the inner wall of the protective cover. A first fan is fixedly connected to the upper surface of the protective cover, and a second fan is fixedly connected to one side of the protective cover. The input end of the second fan is fixedly connected to two blowing hoods. A connecting block is fixedly connected to the upper surface of each blowing hood. The sides of the two connecting blocks that are close to each other are fixedly connected to the outer surface of the protective cover. A filter box is fixedly connected to the input end of the second fan. A filter screen is fixedly connected to the inner wall of the filter box. The input end of the first fan is fixedly connected to the sides of the two suction hoods that are close to each other. A collection box is fixedly connected to the output end of the first fan. Two bearings are fixedly connected to the inner wall of each set of support plates. A winding roller is fixedly connected to the inner ring of each set of bearings. The outer surface of the output end of each drive motor is fixedly connected to the inner ring of two of the bearings.

[0008] Preferably, the bottom surface of the base plate is fixedly connected to four support feet, and the outer surface of each set of support feet is fixedly connected to two fixing rings, and the top of each set of fixing rings is fixedly connected to the bottom surface of the base plate.

[0009] Preferably, a protective box is fixedly connected to the outer surface of each drive motor, and the bottom surface of each protective box is fixedly connected to the upper surface of the base plate.

[0010] Preferably, the outer surface of the output end of the second fan is fixedly connected to two fixing brackets, and one side of each fixing bracket is fixedly connected to one side of the protective cover.

[0011] Preferably, each of the fixing frames is fixedly connected to a fixing frame on its outer surface, and one side of each fixing frame is fixedly connected to one side of the protective cover.

[0012] Preferably, each of the fixed frames has four limit bolts threadedly connected to its inner wall, and the outer surface of each set of limit bolts is threadedly connected to the inner wall of the protective cover.

[0013] Preferably, a reinforcing plate is fixedly connected to the outer surface of each of the connecting blocks, and the side of each of the two reinforcing plates that are close to each other is fixedly connected to the outer surface of the protective cover.

[0014] Preferably, each of the reinforcing plates has four fixing bolts threaded to its inner wall, and the outer surface of each set of fixing bolts is threaded to the inner wall of the protective cover.

[0015] Preferably, a control panel is fixedly connected to the upper surface of the base plate, and the control panel is electrically connected to the first fan and the second fan respectively through wires.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a second fan, two blowers and a filter box, the second fan can deliver clean airflow to the surface of the conductive membrane through the blowers when it is working, effectively loosening the stubborn dust that originally adhered to the membrane surface, breaking the limitation that "sucking alone cannot remove sticky dust". The filter screen of the filter box can pre-treat the airflow entering the second fan to prevent external impurities from adhering to the membrane surface with the airflow. At the same time, the collection box can centrally store the dust, which is convenient for subsequent unified cleaning and avoids dust pollution of the processing environment or internal parts of the equipment.

[0018] 2. By linking two suction hoods with protective covers fixed to the inner wall with the first fan and the collection box, after the dust is loosened by blowing, the first fan can quickly suck in the suspended and detached dust through the suction hoods and transport it to the collection box through the output end for centralized collection, so as to avoid the dust from spreading or falling back onto the membrane surface.

The sides of the two connecting blocks 14 that are close to each other are fixedly connected to the outer surface of the protective cover 3. The outer surface of the output end of the second blower 10 has two fixing brackets 12 fixedly connected to it. One side of each fixing bracket 12 is fixedly connected to one side of the protective cover 3. The fixing brackets 12 can fix and support the output end of the second blower 10, thereby enhancing the stability of the device.

[0030] The input end of the second fan 10 is fixedly connected to the filter box 8. The inner wall of the filter box 8 is fixedly connected to the filter screen 11. The outer surface of each fixed frame 12 is fixedly connected to the fixed frame 17. One side of each fixed frame 17 is fixedly connected to one side of the protective cover 3. The fixed frame 17 can fix the position of the fixed frame 12 to prevent it from swaying during use.

[0031] The input end of the first fan 4 is fixedly connected to the side of the two suction hoods 19 that are close to each other. The output end of the first fan 4 is fixedly connected to the collection box 20. The inner wall of each fixed frame 17 is threaded with four limiting bolts 18. The outer surface of each set of limiting bolts 18 is threadedly connected to the inner wall of the protective cover 3. The position of the fixed frame 17 can be restricted by the limiting bolts 18, which can play the role of fixing and limiting.

[0032] Two bearings 22 are fixedly connected to the inner wall of each set of support plates 2, and a reinforcing plate 15 is fixedly connected to the outer surface of each connecting block 14. The side of the two reinforcing plates 15 that are close to each other is fixedly connected to the outer surface of the protective cover 3. The reinforcing plates 15 can reinforce the connecting block 14 and the protective cover 3 to prevent them from shifting and becoming unstable during use.

[0033] Each bearing 22 has a winding roller 5 fixedly connected to its inner ring. Each reinforcing plate 15 has four fixing bolts 16 threadedly connected to its inner wall.

[0035] The working principle of this utility model is as follows: When in use, the second fan 10 is started first. After the airflow is stably output from the blower hood 13, the first fan 4 is started to form an airflow cycle of "blowing-suction". The drive motor 23 is started and the winding roller 5 drives the conductive film to move at a set speed. Then the laser galvanometer 21 is started to remove the local conductive layer on the surface of the moving conductive film by laser according to the preset parameters. The clean airflow delivered by the second fan 10 is blown obliquely to the surface of the conductive film through the blower hood 13, effectively peeling off the sticky dust that was originally attached, breaking the limitation that "single suction cannot peel off sticky dust".

[0036] The laser energy is focused on the target area of ​​the conductive film by the laser galvanometer 21, instantly vaporizing or dissolving the local conductive layer. The protective cover 3 can isolate the laser from leakage and ensure the safety of the operator. The first fan 4 generates negative pressure by symmetrically distributing two suction hoods 19 on both sides of the laser processing area. The dust loosened by the airflow and the trace debris generated by the laser processing are simultaneously sucked in and transported through the pipeline to the collection box 20 for centralized storage, so as to avoid dust pollution of the processing environment or internal parts of the equipment.
