Thus, when the driving roller 320 rotates, the cleansing roller 330 and the dust collecting roller 340 are also rotated together. The cleansing roller 330 is wound with an adhesive layer 331, and the dust collecting roller 340 is wound with an adhesive tape (not shown).
In use, the cleaning apparatus 10 is disposed before the hot pressing process, and the light guide plate is transferred to the cleansing device 300 through the transfer assembly 200 and passes between the driving roller 320 and the cleansing roller 330. In the process, the light guide plate is clamped by the driving roller 320 and the face cleaning roller 330, the reflective face of the light guide plate is pressed by the face cleaning roller 330, and since the face cleaning roller 330 is provided with the adhesive layer 331, when the face cleaning roller 330 rolls over the reflective face of the light guide plate, the dust attached to the reflective face is adsorbed onto the adhesive layer 331. Since the dust collecting roller 340 is wound with the sticky tape, the dust collecting roller 340 and the face cleaning roller 330 are pressed together, and the sticky tape has better stickiness than the sticky layer 331, so that the dust on the sticky layer 331 will be further stuck to the sticky tape of the dust collecting roller 340. After a certain amount of dust is attached to the sticky tape, the dust collecting roller 340 is taken out, and the outer ring of the sticky tape on the dust collecting roller is torn off, so that the sticky tape becomes clean again, and the dust collecting roller 340 can continue to work. The specific operating principle will be explained below.
Next, the main structure of the cleaning device 10 suitable for a light guide plate of the present invention is explained:
in the present embodiment, as shown in fig. 3, the base 310 is provided with a feeding port 311, a discharging port 312 and a shaft-withdrawing through hole 313 (as shown in fig. 2). The feeding port 311 and the discharging port 312 are disposed opposite to each other, the feeding port 311 and the discharging port 312 are both disposed between the driving roller 320 and the face cleaning roller 330, and the shaft withdrawing through hole 313 is disposed at one end of the dust collecting roller 340. Preferably, the conveying assembly 200 includes a feeding conveyor belt 210 and a discharging conveyor belt 220, the cleaning device 300 is disposed between the feeding conveyor belt 210 and the discharging conveyor belt 220, the feeding conveyor belt 210 extends to a feeding port 311, and the discharging conveyor belt 220 extends to a discharging port 312. When the hot-pressing device is used, the light guide plate is conveyed to the feeding port 311 by the material conveying belt 210, is cleaned and then exits from the discharging port 312, and is conveyed to a hot-pressing process by the material returning conveying belt 220.
In this embodiment, as shown in fig. 3 and 4, an elastic member 350 is disposed between the driving roller 320 and the cleansing roller 330, and the elastic member 350 is disposed at both ends of the driving roller 320 and the cleansing roller 330. Preferably, the elastic member 350 includes: a first bearing collar 351, a second bearing collar 352, a resilient member 353, and a guide rod 354. The first bearing collar 351 is sleeved on the rotating shaft of the driving roller 320, the second bearing collar 352 is sleeved on the rotating shaft of the face cleaning roller 330, the elastic member 353 is installed between the first bearing collar 351 and the second bearing collar 352, and the guide rod 354 penetrates through the first bearing collar 351 and the second bearing collar 352. The main function of the elastic assembly 350 is to provide elastic tension, when the position of the cleaning roller 330 on the base 310 is unchanged, the gap between the driving roller 320 and the cleaning roller 330 becomes larger when the light guide plate passes between the driving roller 320 and the cleaning roller 330; when the light guide plate is separated, the elastic member 353 provides a pulling force to the driving roller 320 to approach and re-contact the cleaning roller 330.
Further, in this embodiment, as shown in fig. 4 and fig. 5, the dust collecting roller 340 is provided with third bearing collars 341 at both ends, the base is provided with a lifting cylinder 342, and the telescopic rod of the lifting cylinder 342 is movably connected with the third bearing collars 341. After the dust collecting roller 340 is installed, the lifting cylinder 342 lifts the dust collecting roller 340 through the third bearing collar 341, the lifted dust collecting roller 340 is attached to the face cleaning roller 330, and the lifted dust collecting roller 340 can only rotate because the third bearing collar 341 is sleeved with the rotating shaft of the dust collecting roller 340; when a part of the sticky tape needs to be torn off, the dust collecting roller 340 is firstly drawn out, the lifting cylinder 342 is disconnected from the third bearing collar 341, the position of the dust collecting roller 340 descends, and the dust collecting roller 340 is not attached to the face cleaning roller 330, so that the dust collecting roller 340 can be smoothly taken out. Preferably, as shown in fig. 5, a pin 343 is disposed on the telescopic rod of the lifting cylinder 342, and an insertion hole (not shown) is disposed on the third bearing collar 341, so that the telescopic rod of the lifting cylinder 342 is movably connected to the third bearing collar 341 through the cooperation of the pin 343 and the insertion hole.
In the present embodiment, as shown in fig. 2 and 3, the base 310 is provided with a bottom plate 314, the bottom plate 314 has an arc structure, and the bottom plate 314 is disposed below the dust collecting drum 340. When the lift cylinder 342 is disconnected from the third bearing collar 341, the dust collection roller 340 drops onto the bottom tray 314, i.e., when the lift cylinder 342 no longer lifts the dust collection roller 340, the bottom tray 314 provides support for the dust collection roller 340.
So far, the description of the main structure of the cleaning device 10 of the present invention is completed. Next, the operation principle of the cleaning device 10 will be explained with reference to the above structure, and please refer to fig. 1, fig. 3 and fig. 4:
in use, the light guide plate is conveyed to the feeding port 311 by the feeding conveyor 210 and then enters the cleansing device 300. Under the rotation action of the driving roller 320, the light guide plate enters the gap between the driving roller 320 and the face cleaning roller 330 and is clamped by the driving roller 320 and the face cleaning roller 330; as the driving roller 320 and the cleaning roller 330 rotate, the light guide plate gradually passes through the driving roller 320 and the cleaning roller 330. In the process, the cleaning roller 330 is tightly attached to one side (reflective surface) of the light guide plate, and since the cleaning roller 330 is provided with the adhesive layer 331, the dust attached to the reflective surface is adsorbed onto the adhesive layer 331 during the attachment. The light reflecting surface of the light guide plate is cleaned, and the cleaned light guide plate exits from the discharge hole 312 and is conveyed to the subsequent process through the material returning conveyor belt 220; after the light guide plate exits, the elastic member 353 provides a pulling force to the driving roller 320, so that the driving roller is free from the gap and is in contact with the cleaning roller 330 again;
when the light guide plate is cleaned, the dust collecting roller 340 is lifted by the lifting cylinder 342 and attached to the face cleaning roller 330, so that the dust collecting roller 340 is also driven when the face cleaning roller 330 rotates. Since the viscosity of the sticky tape is better than that of the sticky layer 331, the dust on the sticky layer 331 will be further stuck to the sticky tape of the dust collecting roller 340 during the rotation process. Thus, dust on the adhesive tape is continuously accumulated over time;
after the dust has accumulated to a certain amount, the operator takes out the dust collecting drum 340, specifically: firstly, the telescopic rod of the lifting cylinder 342 is retracted, so that the position of the dust collecting roller 340 gradually descends until the dust collecting roller falls on the supporting bottom plate 314, and at the moment, the dust collecting roller 340 is not attached to the face cleaning roller 330 any more. Then, the telescopic rod of the lifting cylinder 342 is further recovered, so that the pin 343 is disengaged from the insertion hole, and the third bearing collar 341 is no longer connected with the lifting cylinder 342, so that the dust collecting drum 340 can be smoothly taken out. After the dust collection roller 340 is taken out, the operator tears off the outer ring of the sticky tape of the dust collection roller 340, so that the sticky tape becomes clean again, the dust collection roller 340 is inserted into the base 310 again, the lifting cylinder 342 jacks up the dust collection roller 340 again, and the dust collection roller 340 is attached to the face cleaning roller 330, so that the dust collection roller 340 can continue to work.
It should be noted that, in the cleaning device 10 of the present invention, the dust on the light reflecting surface of the light guide plate is adsorbed twice during the cleaning process. For the first time, the dust is adsorbed from the reflective surface to the adhesive layer 331 of the cleansing drum 330; second, the dust is adsorbed from the adhesive layer 331 to the adhesive tape of the dust collecting roller 340. Compared with the traditional spray cleaning method, the light guide plate cleaned by the cleaning equipment 10 does not need to be dried, and can quickly enter a hot-pressing process. Moreover, by providing the dust collecting roller 340, dust is continuously accumulated on the adhesive tape by the second adsorption during the cleaning process, and the adhesive layer 331 of the cleansing roller 330 can be kept relatively clean. When the old adhesive tape is torn off, the cleaning device 10 does not need to be paused, i.e., the cleaning roller 330 does not need to stop rotating, and it can still clean the light guide plate. Thus, the cleaning device 10 of the present invention can clean the light guide plate without stopping, thereby improving the cleaning efficiency.
In one embodiment, as shown in FIG. 6, dust guard 221 is provided on the return conveyor 220. The cleaned light guide plate exits from the discharge port 312 and enters the material returning conveyor belt 220, and after the dust cover 221 is installed, the light guide plate can be effectively prevented from being stained with dust again, so that the cleanness of the light guide plate is kept.
To sum up, the utility model discloses a cleaning device 10 suitable for light guide plate can conveniently clean the light guide plate fast before hot pressing process to improve work efficiency.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
