Description

Cleaning device for display and its control method {DISPLAY PART CLEANING APPARATUS AND CLEANING METHOD THEREOF}

The present invention relates to a cleaning apparatus for a display unit and a control method thereof, and more particularly, to a cleaning apparatus for a display unit capable of preventing damage to a screen display unit and a connector unit from being damaged, and a control method thereof.

In general, a display unit is installed in a mobile device such as a smartphone or a tablet. The display unit includes a screen display unit and a cover glass. A cover glass is attached to the outer surface of the screen display by an optical adhesive layer. The screen display unit is formed by stacking a thin film transistor, a photodiode layer and a polarizing layer, a liquid crystal, a color filter, and a polarizing layer. A flexible circuit board is stacked on the screen display part, and the connector part of the screen display part is connected to the flexible circuit board.

The cover glass is separated from the screen display to recycle the screen display. Wait about 5-10 minutes after applying the chemical solution to the adhesive layer of the screen display. When the adhesive layer is sufficiently soaked with the cleaning liquid, the adhesive layer is scraped off using a metal wire brush. The stain remaining on the screen display is removed using a cleaning solution.

However, conventionally, since the cleaning liquid is used in all cleaning processes to clean the adhesive layer in the screen display, the amount of cleaning liquid is increased, and a post-treatment process of the cleaning liquid is required. Accordingly, the cleaning process becomes complicated, and environmental pollution by the cleaning liquid may increase.

In addition, since the adhesive layer is scraped off by using a metal wire brush, the surface of the screen display may be damaged.

In addition, when the cleaning liquid is applied to the screen display, the banding protective layer may be damaged by the cleaning liquid as the cleaning liquid is applied to the banding protective layer. If the bending protective layer is damaged, the connector or the connector may be damaged or short-circuited when the flexible circuit board is bent or by an external impact. In addition, since the connector portion is exposed to the outside, moisture may penetrate into the connector portion or a peeling phenomenon may occur between the connector portion and the banding protective layer.

In addition, since protrusions such as electronic devices, electrodes, and solder balls are installed on the screen display unit, the screen display unit may be pressed when the adhesive layer is scraped off the screen display unit. As the screen display unit is pressed, pressing marks may be generated on the screen display unit due to the reaction force of protrusions such as electronic devices, electrodes, and solder balls.

A method of controlling the cleaning apparatus for a display unit according to an embodiment of the present invention configured as described above will be described.

FIG. 27 is a flow chart showing a method of controlling a physical cleaner in the cleaning apparatus for a display according to an embodiment of the present invention, and FIG. 28 is a control method of a chemical cleaner in the cleaning apparatus for a display according to an embodiment of the present invention. This is the illustrated flow chart.

Referring to FIGS. 27 and 28, the method of controlling a cleaning apparatus for a display according to an embodiment of the present invention is a step of physically removing the optical adhesive layer 30 attached to the screen display 11 by the physical cleaners 100, 200, and 300. And, by the chemical cleaners 400 and 500, removing the marks on the screen display unit 11 by using a cleaning solution on the screen display unit 11.

The step of physically removing the optical adhesive layer 30 attached to the screen display 11 by the physical cleaners 100, 200, 300 includes the optical adhesive layer 30 to which the first cleaner 100 is attached to the inside of the surface of the screen display 11 And physically removing the adhesive layer remaining on the edge portion 11a of the screen display 11 by the second cleaner 200.

A step in which the first cleaner 100 physically removes the optical adhesive layer 30 attached to the inside of the surface of the screen display 11 will be described.

The screen display unit 11 is seated on the first cleaning stage unit 110, and the protrusion 15 of the screen display unit 11 presses and deforms the first damage prevention unit 120 (S11). At this time, the protrusion 15 is buried in the first damage prevention part 120 as the first damage prevention part 120 is deformed. In addition, since the first damage prevention part 120 flows upward to support the protrusion 15 and its circumferential part, the screen display 11 is formed by the first cleaning stage part 110 and the first damage prevention part 120. The entire underside of is supported by a uniform pressure. Accordingly, it is possible to prevent the occurrence of pressing marks on the screen display unit 11 due to the reaction force of the protrusion unit 15 when the screen display unit 11 is pressed.

The first suction port part 115 vacuum-adsorbs the screen display part 11 (S12). In addition, the clamp unit 140 presses the screen display unit 11 to the first cleaning stage unit 110 and makes it in close contact. Since the screen display unit 11 is in close contact with the first cleaning stage unit 110 by the vacuum suction force and the pressing force of the clamp unit 140, the screen display unit 11 is pushed by the pressing force of the first cleaning roller unit 130 Can prevent folding.

The first heating unit 150 heats the adhesive layer 31 of the screen display unit 11 (S13). As the first heating unit 150 heats the optical adhesive layer 30, the optical adhesive layer 30 is softened, so that the removal efficiency of the optical adhesive layer 30 can be improved.

As the first cleaning roller unit 130 is rotated, the optical adhesive layer 30 of the screen display unit 11 is removed (S14). Since the adhesive layer 31 softened on the heating unit is removed by the rotational frictional force of the first cleaning roller unit 130, the screen display unit 11 is hardly pressed. Accordingly, it is possible to prevent the screen display 11 from being damaged.

The screen display unit 11 cleaned by the first cleaning stage unit 110 is mounted on the second cleaning stage unit 210 and 210 (S15). As the second damage preventing portion 220 flows upwards of the second receiving groove portions 213 and 213 by the pressure of the protrusion portion 15, the lower surface of the screen display portion 11 is supported. In addition, the protrusion 15 is embedded in the second damage prevention part 220 as the second damage prevention part 220 is deformed. Accordingly, even if the screen display 11 is pressed, it is possible to prevent the protrusion 15 from being damaged. In addition, it is possible to prevent the occurrence of pressing marks on the screen display unit 11 by the reaction force of the protrusions 15.

A protector unit 240 is provided to cover the banding protection layer 13 and the connector unit 14 disposed at the periphery of the screen display unit 11. Since the protector part 240 covers the connector part 14 and the banding protective layer 13, the cleaning liquid adheres to the connector part 14 and the banding protective layer 13 when the cleaning liquid is applied to the screen display part 11 Can be prevented.

Accordingly, it is possible to prevent the connector portion 14 and the banding protective layer 13 from being damaged by the cleaning liquid.

The second cleaner 200 physically removes the adhesive layer remaining on the edge portion 11a of the screen display 11. This will be described in detail.

The screen display unit 11 cleaned by the first cleaning stage unit 110 is mounted on the second cleaning stage unit 210 (S15).

As the second damage prevention part 220 is pressed by the protrusion 15, it is deformed. The second suction port part 215 of the second cleaning stage part 210 vacuum-adsorbs the screen display part 11 (S16). At this time, as the second damage preventing part 220 flows upwards of the protruding part 15, the protruding part 15 is buried in the second damage preventing part 220, so even if the screen display part 11 is pressed, the protruding part 15 Can be prevented from being damaged. In addition, it is possible to prevent the occurrence of pressing marks on the screen display unit 11 due to the reaction force of the protrusion unit 15.

The second heating unit 217 heats the optical adhesive layer 30 of the screen display unit 11 (S17). At this time, since the optical adhesive layer 30 is softened, the optical adhesive layer 30 can be more easily removed from the screen display 11.

As the second cleaning roller part 230 rotates, the adhesive layer remaining on the edge part 11a of the screen display part 11 is removed (S18). In this case, the second cleaning roller unit 230 is disposed parallel to the surface of the screen display unit 11 and inclined with the width direction of the screen display unit 11. Accordingly, when the second cleaning roller 235 is rotated, the adhesive layer removed from the screen display unit 11 may be moved along the lengthwise direction of the second cleaning roller unit 230.

The second cleaning roller unit 230 removes the adhesive layer while being rotated to push the adhesive layer toward the transport direction of the second cleaning roller unit 230. For example, the second cleaning roller 235 is transferred to the front side along one edge portion 11a of the screen display 11 and rotates counterclockwise. In addition, when the second cleaning roller 235 is transferred to the rear side along the other edge portion 11a of the screen display unit 11, it rotates clockwise. At this time, the second cleaning roller 235 is disposed to be inclined so that one end of the second driving unit 231 precedes the other end of the opposite side of the second driving unit 231. Since the second cleaning roller 235 is rotated to push the adhesive layer in the conveying direction side, it is possible to prevent the adhesive layer from re-adhering to the rear side of the second cleaning roller 235. Therefore, it is possible to improve the removal performance of the adhesive layer.

The second air injection nozzle 240 injects air toward the second cleaning roller unit 230. Since the second air injection nozzle 240 injects air toward the second cleaning roller 235, the adhesive material removed by the second cleaning roller 235 may be discharged to the outside of the screen display unit 11. Accordingly, it is possible to prevent the adhesive material from being attached to the screen display unit 11 again.

The second heated air supply unit 250 may supply heated air to the second air injection nozzle 240. Therefore, since the second air injection nozzle 240 injects high-temperature heated air toward the second cleaning roller 235, the removal performance of the adhesive layer may be improved as the adhesive layer of the screen display 11 softens. .

In the step of physically removing the optical adhesive layer 30 attached to the screen display unit 11 by the physical cleaners 100, 200, 300, the third cleaner 300 remains on the screen display unit 11 cleaned by the second cleaner 200. It further comprises the step of physically removing the adhesive material. In the third cleaner 300, since the cleaning liquid is not used and the adhesive material is physically removed, it is possible to prevent environmental pollution caused by the cleaning liquid.

The screen display unit 11 is mounted on the third cleaning stage unit 310, and the protrusion 15 of the screen display unit 11 presses and deforms the third damage prevention unit. At this time, the fourth suction port part 415 of the third cleaning stage part 310 vacuum-adsorbs the screen display part 11 (S19, S20). Since the third suction port part 314 vacuum-adsorbs the screen display part 11, it is possible to prevent the screen display part 11 from being changed in position in the third cleaning stage part 310 when the screen display part 11 is cleaned. have.

In addition, as the third damage prevention part 320 flows upwards of the protrusion 15, the protrusion 15 is buried in the third damage prevention part, so even if the screen display 11 is pressed, the protrusion 15 is damaged. Can be prevented. In addition, it is possible to prevent the occurrence of pressing marks on the screen display unit 11 due to the reaction force of the protrusion unit 15.

As the third cleaning brush unit 330 is rotated, the adhesive material remaining on the screen display unit 11 is removed. As the third cleaning brush unit 330 is rotated to remove the adhesive material, the cleaning liquid is not used when removing the adhesive material. Therefore, it is possible to prevent environmental pollution by the cleaning liquid.

In a state in which the third flat brush unit 331 is disposed parallel to the surface of the screen display unit 11, the adhesive material of the screen display unit 11 is removed (S21). Since the third flat brush unit 331 is rotated while being disposed parallel to the surface of the screen display unit 11, the adhesive material remaining on the plane of the screen display unit 11 can be easily removed.

In a state in which the third inclined brush portion 333 is obliquely disposed on the edge portion 11a of the screen display portion 11, the adhesive material remaining on the edge portion 11a of the screen display portion 11 is removed (S21). Since the third inclined brush part 333 is rotated in an inclined state, the adhesive material attached to the side of the edge part 11a of the screen display part 11 or caught in the gap of the edge part 11a may be removed. In addition, since the third inclined brush part 333 does not interfere with the connector part 14, the connector part 14 of the screen display part 11 is prevented from being damaged or deformed when the third inclined brush part 333 is rotated. can do.

The chemical cleaners 400 and 500 remove marks on the screen display 11 by using a cleaning solution on the screen display 11. This will be described in detail.

The screen display unit 11 is seated on the fourth cleaning stage unit 410 (S31). In this case, the edge portion 11a of the screen display unit 11 overlaps the inner edge portion 443 of the fourth cleaning liquid suction unit 440 by a predetermined width W or more. In addition, the protrusion 15 of the screen display unit 11 is located on the fourth damage prevention unit 416, and the banding protective layer 13 and the connector unit 14 of the screen display unit 11 are provided with a fourth cleaning liquid suction unit ( It is accommodated in the fourth damage prevention groove 445 of the 440. Accordingly, it is possible to prevent the screen display unit 11 from being separated from the fourth cleaning stage unit 410 due to a step difference between the banding protection layer 13 and the connector unit 14.

The screen display unit 11 is vacuum-adsorbed to the fourth cleaning stage unit 410 by the fourth suction port unit 413 (S32). Since the fourth adsorption port part 413 vacuum-adsorbs the screen display part 11, it is possible to prevent the screen display part 11 from being changed in position in the fourth cleaning stage body part 411.

In addition, as the screen display unit 11 is vacuum-adsorbed, the protrusion 15 of the screen display unit 11 presses the fourth damage preventing unit 416. As the fourth damage prevention part 416 is pressed by the protrusion 15, the fourth damage prevention part 416 flows upward to support the protrusion 15 and its circumference. In addition, since the protrusion 15 is buried inside the fourth damage prevention unit 416, even if the screen display 11 is attached to the fourth cleaning stage unit 410, it is possible to prevent the protrusion 15 from being damaged. . In addition, it is possible to prevent the occurrence of pressing marks on the screen display unit 11 due to the reaction force of the protrusion unit 15.

The fourth protector unit 470 covers the banding protection layer 13 and the connector unit 14 of the screen display unit 11 (S33). Since the fourth protector unit 470 covers the banding protection layer 13 and the connector unit 14 of the screen display unit 11, when the fourth cleaning pad unit 430 is moved to clean the screen display unit 11 It is possible to prevent the bending protective layer 13 and the connector part 14 of the screen display 11 from being torn or deformed by the fourth cleaning pad part 430.

The fourth cleaning solution supply unit 420 supplies the cleaning solution to the fourth cleaning pad unit 430 (S34). In this case, the cleaning liquid of the fourth cleaning liquid tank part 425 is supplied to the fourth cleaning pad part 430 through the fourth cleaning liquid supply line part 421. As the cleaning liquid is absorbed in the fourth cleaning pad part 430, the fourth cleaning pad part 430 is wetted by the cleaning liquid.

As the fourth cleaning motor unit 435 descends, the fourth cleaning pad unit 430 is in close contact with the screen display unit 11 (S35). At this time, since the fourth cleaning pad unit 130 is formed of a soft material, the fourth cleaning pad unit 430 hardly presses the screen display unit 11, so that when the fourth cleaning pad unit 430 is moved or rotated Damage to the screen display 11 can be prevented.

As the fourth cleaning pad unit 430 in which the cleaning liquid is absorbed is transferred, the screen display unit 11 is cleaned (S36). In this case, the fourth cleaning pad unit 430 may be moved while being rotated or may be moved without being rotated.

For example, the fourth cleaning pad unit 430 may be moved to one side of the screen display unit 11 while being rotated forward, and moved to the other side of the screen display unit 11 while rotating backward to clean the screen display unit 11. . In this case, the fourth cleaning pad unit 430 may be rotated at a rotation speed of 500-600 rpm and may be moved at a speed of 1200-1700mm/s to clean the screen display unit 11.

In addition, the fourth cleaning pad unit 430 may clean the screen display unit 11 while being reciprocated to one side and the other side of the screen display unit 11 without being rotated. In this case, the fourth cleaning pad unit 430 may clean the screen display unit 11 while moving at a speed of 2500-3500 mm/s.

In addition, the fourth cleaning pad unit 430 may first clean the screen display unit 11 while being rotated and moved, and may secondarily clean the screen display unit 11 while moving in an unrotated state. In addition, the fourth cleaning pad unit 430 may first clean the screen display unit 11 while being moved in an unrotated state, and may secondarily clean the screen display unit 11 while rotating and moving.

At this time, since the fourth ground unit 416 is connected to the fourth cleaning stage unit 410, static electricity generated when the screen display unit 11 is cleaned is removed by the fourth ground unit 416. Accordingly, it is possible to prevent the internal components of the screen display 11 from being shorted by static electricity. In addition, it is possible to significantly reduce the possibility of a fire by preventing the volatile cleaning liquid from being ignited by static electricity.

The fourth cleaning liquid supply unit 420 stops supply of the cleaning liquid to the fourth cleaning pad unit 430 (S37). At this time, the fourth cleaning liquid supply valve 422 closes the flow path of the fourth cleaning liquid supply line part 421. As the supply of the cleaning liquid to the fourth cleaning pad unit 430 is stopped, it is possible to prevent excessive flow of the cleaning liquid to the screen display unit 11. When cleaning the fourth cleaning pad unit 430, the fourth cleaning solution supply unit 420 may supply the cleaning solution to the fourth cleaning pad unit 430 at a predetermined period.

As the suction pressure is generated in the fourth suction chamber part 450, the cleaning liquid of the screen display 11 is sucked into the fourth cleaning liquid suction part 440 (S38 ). At this time, since the inner edge portion 443 of the fourth cleaning liquid suction unit 440 is disposed to overlap with the edge portion 11a of the screen display 11, the edge portion 11a of the screen display 11 The suction pressure of the fourth cleaning liquid suction unit 440 is applied. Accordingly, the cleaning liquid flowing downward along the edge portion 11a of the screen display 11 may be sucked into the fourth cleaning liquid suction unit 440. In addition, since it is possible to prevent marks caused by a cleaning liquid or the like on the lower surface of the screen display unit 11, it is not necessary to clean the lower surface of the screen display unit 11 after cleaning of the screen display unit 11 is completed.

The cleaning liquid sucked from the fourth cleaning liquid suction part 440 flows into the fourth suction chamber part 450 (S39). At this time, the cleaning liquid sucked from the fourth cleaning liquid suction unit 440 is recovered to the fourth vacuum tank unit 453 through the fourth suction line unit 451.

A suction pressure is formed in the fourth suction chamber part 450 so that the cleaning liquid is vaporized (S40). In this case, a suction pressure equal to or less than the saturated vapor pressure of the cleaning liquid is formed in the fourth vacuum tank 453 so that the cleaning liquid is vaporized. Since a pressure equal to or lower than the saturated vapor pressure of the cleaning liquid is formed in the fourth vacuum tank 453, the generation rate of cleaning vapor can be increased as the cleaning liquid is evaporated when the cleaning liquid flows into the fourth vacuum tank 453. have.

In addition, since the fourth heating unit 456 installed inside the fourth suction chamber unit 450 heats the cleaning liquid, vaporization of the cleaning liquid can be further promoted.

The cleaning vapor vaporized in the fourth suction chamber part 450 is discharged into the atmosphere through the fourth exhaust part 455 (S41). Therefore, a post-treatment process of the cleaning liquid is not required. In addition, the cleaning process can be simplified, and the post-treatment cost and cleaning time can be reduced. In addition, when the cleaning liquid is an eco-friendly volatile cleaning liquid such as ethanol, methanol, or ketone, even if the cleaning vapor is discharged into the atmosphere, it may hardly cause environmental pollution. It can also satisfy environmental regulations.

The fourth cleaning pad unit 430 is moved to the outside of the screen display unit 11 (S42). At this time, rotation of the fourth cleaning pad unit 430 is stopped, and the fourth cleaning liquid supply unit 420 does not supply the cleaning liquid to the fourth cleaning pad unit 430.

As the fourth protector driving unit 475 is driven, the fourth protector unit 470 is moved to the outside of the fourth cleaning liquid suction unit 440 (S43). At this time, when the fourth protector frame part 471 is moved to the outside of the fourth cleaning liquid intake part 740, the banding protection layer 13 of the screen display part 11 and the connector part 14 are released from restraints. Accordingly, the screen display unit 11 may be discharged from the fourth cleaning stage unit 410 by a pickup device (not shown).

When cleaning of the screen display unit 11 is completed, foreign substances are removed from the fourth cleaning solution suction unit 440 as air from the fourth suction chamber unit 450 is supplied to the fourth cleaning solution suction unit 440 (S44). . At this time, when the fourth air pump 457 sucks air into the fourth vacuum tank unit 453 and increases the pressure of the fourth vacuum tank unit 453, the air in the fourth vacuum tank unit 453 is It is supplied to the fourth cleaning liquid suction unit 440 through the fourth suction line unit 451. Accordingly, since foreign substances clogged in the holes of the fourth cleaning liquid suction unit 440 are removed, the life of the fourth cleaning liquid suction unit 440 may be extended.

As the fourth hood part 460 is driven, foreign substances removed from the fourth cleaning liquid suction part 40 are sucked into the fourth hood part 460 (S45). Since the fourth hood part 460 sucks the foreign substance, it is possible to prevent the fourth cleaning liquid suction part 440 from being contaminated or clogged again by the foreign substance.

The chemical cleaners 400 and 500 include the step of removing marks on the screen display 11 by using a cleaning solution on the screen display 11. This will be described in detail below.

The screen display unit 11 is mounted on the fifth cleaning stage unit 510 (S46). The fifth adsorption port part 515 makes the screen display part 11 in close contact with the fifth cleaning stage part 510 by vacuum pressure (S47).

The water supply port part 345 sprays the cleaning liquid onto the cleaning sheet part 535 (S48). Accordingly, the cleaning liquid is absorbed by the cleaning sheet portion 535.

As the pressing pad unit 340 is moved, the cleaning sheet unit 535 is in close contact with the screen display unit 11 (S49). At this time, the cleaning sheet part 535 is in close contact with the surface of the screen display part 11 by the vacuum pressure of the pressing pad part 340.

The cleaning sheet portion 535 unwound by the fifth unwinding winding portion 531 is wound around the fifth winding winding portion 333. At this time, as the cleaning sheet part 535 wet with the cleaning liquid is transferred, the screen display 11 is cleaned (S50),

The injection of the cleaning liquid from the water supply port part 345 is stopped (S51). As the spraying of the cleaning liquid from the water supply port part 345 is stopped, the dry cleaning sheet part 535 is transferred to the screen display part 11. Accordingly, as the dry cleaning sheet unit 535 is transferred, the screen display unit 11 is dried (S52).

The pressing pad unit 340 is raised, and the fifth unwinding winding unit 531 and the fifth winding winding unit 333 are stopped. Subsequently, the drying unit 350 sprays air while moving from the upper side of the screen surface after the pressure pad unit 340 is raised. As air is injected from the drying unit 350, the cleaning liquid remaining on the screen display unit 11 is evaporated.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible. I will understand.
