Description

Technical Field

[0001] This utility model relates to the field of LED display screen film application technology, specifically a film application device for LED display screen production. Background Technology

[0002] LED displays are electronic display devices that use light-emitting diodes (LEDs) as pixels to display images, videos, and text information. They are widely used in equipment operation screens, equipment displays, billboards, stage backdrops, traffic signs, indoor and outdoor displays, and other scenarios. By controlling the brightness and color of each LED, LED displays can create various colors and patterns. LEDs themselves are semiconductor devices that emit light of a specific wavelength when current passes through them, which is the color of visible light. During the production of LED displays, a protective film needs to be applied to the surface of the LED display to prevent scratches and damage during transportation.

[0003] Currently, when applying film to the surface of LED displays, workers simply wipe the surface with a cloth to clean away dust. During the assembly of the LED screen, lubricants or other additives may be used to help assemble the components. These substances may remain on the screen surface, and the sweat from workers' hands during operation may also cause oil stains on the screen surface. Cleaning with just a cloth will result in incomplete cleaning, leading to the film not being firmly applied and easily falling off. Utility Model Content

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-5 As shown, an LED display screen production film application equipment includes: a flat film application machine 1, a cleaning machine 2 disposed at one end of the flat film application machine 1, the flat film application machine 1 consisting of a material rack, a feeding shaft, a traction roller and a PLC programmable controller, an active cavity 3 opened inside the cleaning machine 2, and a cleaning component disposed inside the cleaning machine 2, the cleaning component including: a liquid storage tank 201, a liquid pump 202, a liquid extraction pipe 203, a delivery pipe 204, a cleaning nozzle 205, a cleaning block 206 and an observation window 207.

[0025] The movable cavity 3 is equipped with a conveyor 4, which is connected to a patterned conveyor belt 401 via a rotating shaft. A workbench 402 is provided on one side of the outer end of the conveyor 4. After the LED display screen is assembled, it is placed on the workbench 402 to prevent it from falling and to facilitate its handling. When cleaning the LED display screen, it is picked up and placed on the patterned conveyor belt 401. A servo motor is installed at the outer end of the conveyor 4 to drive the patterned conveyor belt 401. The servo motor is started to drive the patterned conveyor belt 401 to rotate inside the movable cavity 3, so that the LED display screen is transported to the cleaning machine 2 via the patterned conveyor belt 401 for cleaning. The patterned conveyor belt 401 is a rubber-type patterned conveyor belt 401. The pattern on its surface increases the friction with the LED display screen, preventing the LED display screen from shifting during transport and ensuring that the LED display screen is placed stably.

[0026] The cleaning machine 2 has a liquid storage tank 201 installed on top, a liquid pump 202 installed at the top inside the cleaning machine 2, a liquid extraction pipe 203 installed between the liquid pump 202 and the liquid storage tank 201, an "L" shaped delivery pipe 204 installed on one side of the outer end of the liquid pump 202, cleaning nozzles 205 installed on both sides of the bottom of the delivery pipe 204, a cleaning block 206 provided on one side of the cleaning nozzle 205, and an observation window 207 installed on the outer side of the cleaning machine 2 at a position relative to the cleaning nozzles 205 and the cleaning block 206. A tempered transparent glass is embedded inside the observation window 207.

[0027] When the LED display screen is transported to the cleaning machine 2, its movement can be observed through the observation window 207. When the LED display screen passes the bottom of the cleaning nozzle 205, the liquid pump 202 is activated by the control box 502. The liquid pump 202 generates negative pressure suction inside the suction pipe 203, drawing out the alcohol solution stored in the storage tank 201. The alcohol solution has a concentration of 70% and is discharged from the liquid pump 202 into the delivery pipe 204. The delivery pipe 204 then discharges the solution into the cleaning nozzle 205, forming a spray that is sprayed onto the surface of the LED display screen. When the LED display screen passes the cleaning block 206, the alcohol spray from the cleaning block 206 comes into contact with the surface of the LED display screen for wiping and cleaning. This effectively removes residual oil stains from the surface of the LED display screen and ensures that the film is firmly adhered when applying it to the surface of the LED display screen, preventing the film from falling off and avoiding scratches or damage to the surface of the LED display screen during transportation.

[0028] The cleaning machine 2 has an electric push rod 208 installed at the top inside, and a fixing frame 209 installed at the bottom of the electric push rod 208. The fixing frame 209 and the cleaning block 206 are fixedly installed by bolts. When using the cleaning block 206, the cleaning block 206 is installed at the fixing frame 209, and the height of the cleaning block 206 is adjusted by the electric push rod 208 so that the cleaning block 206 can fit against the surface of the LED display screen and wipe away the residual oil stains on the surface of the LED display screen with alcohol spray.

[0029] The cleaning block 206 is equipped with a fan 210 on one side. The fan 210 has an air outlet 211 at the bottom. After the alcohol spray is used to clean the surface of the LED display screen, the alcohol evaporates quickly and dries the screen rapidly. When the screen passes through the fan 210, the fan 210 is activated and blows air from the air outlet 211 onto the surface of the LED display screen for further drying. This ensures that the surface of the LED display screen is dry and avoids affecting the quality of the film application.

[0030] The storage tank 201 has a liquid level sensor 5 installed on one side of its bottom interior. A sound and light warning light 501 is installed on the top of the cleaning machine 2. A control box 502 is installed on the outside of the cleaning machine 2. The liquid level sensor 5 and the sound and light warning light 501 are connected to the control box 502 via wires. A filling hopper 503 is installed on one side of the top of the storage tank 201, and a sealing cap is threaded onto the top of the filling hopper 503. The storage tank 201 stores a 70% alcohol solution. When using the solution, the amount of alcohol solution will decrease as it is extracted during use. As the liquid level gradually decreases, when the level of the alcohol solution inside the storage tank 201 is lower than that of the level sensor 5, the level sensor 5 can send the detected information to the control box 502 via an electrical signal. After processing the information, the control box 502 activates the audible and visual warning light 501, causing the audible and visual warning light 501 to emit an alarm sound and light up, so that the staff can see that the alcohol solution inside the storage tank 201 is almost used up, and then add alcohol solution to the storage tank 201 in time for backup, so as to avoid downtime affecting the work progress.

[0031] When adding alcohol solution, loosen and open the sealing cap on the top of the filling hopper 503, and pour the alcohol solution from the filling hopper 503 into the storage tank 201.

[0032] The cleaning machine 2 has an inspection port 6 on the back. A protective door 601 is connected to the outside of the inspection port 6 by a hinge. When the cleaning machine 2 is in use, the protective door 601 on the outside of the inspection port 6 can be opened to facilitate the inspection, maintenance and replacement of the components installed inside the cleaning machine 2, so as to ensure that the components inside the cleaning machine 2 can be used normally.

[0033] Working principle:

[0034] After the LED display screen is assembled, it is placed on the workbench 402 to prevent it from falling and to facilitate handling. When cleaning the LED display screen, it is picked up and placed on the patterned conveyor belt 401. A servo motor is installed at the outer end of the conveyor 4 to drive the patterned conveyor belt 401. The servo motor is started to drive the patterned conveyor belt 401 to rotate inside the movable cavity 3, so that the LED display screen is transported to the cleaning machine 2 for cleaning. The patterned conveyor belt 401 is a rubber-type patterned conveyor belt 401. The pattern on its surface increases the friction with the LED display screen, preventing the LED display screen from shifting during transport and ensuring that the LED display screen is placed stably.

[0035] When the LED display screen is transported to the cleaning machine 2, its movement can be observed through the observation window 207. When the LED display screen passes the bottom of the cleaning nozzle 205, the liquid pump 202 is activated by the control box 502. The liquid pump 202 generates negative pressure suction inside the suction pipe 203, drawing out the alcohol solution stored in the storage tank 201. The alcohol solution has a concentration of 70% and is discharged from the liquid pump 202 into the delivery pipe 204. The delivery pipe 204 then discharges the solution into the cleaning nozzle 205, forming a spray that is sprayed onto the surface of the LED display screen. When the LED display screen passes the cleaning block 206, the alcohol spray from the cleaning block 206 comes into contact with the surface of the LED display screen for wiping and cleaning. This effectively removes residual oil stains from the surface of the LED display screen and ensures that the film is firmly adhered when applying it to the surface of the LED display screen, preventing the film from falling off and avoiding scratches or damage to the surface of the LED display screen during transportation.

[0036] After wiping the surface of the LED display screen with alcohol spray, the alcohol evaporates quickly and dries rapidly. When the LED display screen is conveyed through the fan 210, the fan 210 is activated, and the fan 210 generates airflow that blows from the air outlet 211 onto the surface of the LED display screen for further drying. This ensures that the surface of the LED display screen is dry and avoids affecting the quality of the film application. After cleaning and drying the surface of the LED display screen, the LED display screen is removed from the patterned conveyor belt 401 and placed on the flat film application machine 1. The flat film application machine 1 applies a film to the surface of the LED display screen. The flat film application machine 1 is a mature and commonly used technology in this field and can be purchased from the market. It is not within the scope of innovation of this application. Therefore, the operation steps and working principle of the flat film application machine 1 will not be described in detail. It is common knowledge and its structural features and usage steps are clearly and unambiguously known to those skilled in the art.

[0037] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
