Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of Low-E coating lines, and in particular relates to a clean room for a Low-E coating line. Background Art
[0002] The Low-E coating line is a production line for producing Low-E glass, where Low-E glass is low-radiation glass. It is a coated glass, which is a film product composed of multiple layers of metal or other compounds coated on the glass surface. Low-E glass has the characteristics of high transmittance to visible light and high reflection to mid- and far-infrared rays, so it has excellent heat insulation effect and good light transmittance.
[0003] The clean room of the Low-E coating line is also called a clean room or dust-free room. It is a transition area between the cleaning machine and the coating machine. A clean environment is formed by isolating the first roller in the transition area from the workshop environment. Its main function is to prevent the glass cleaned by the cleaning machine from being contaminated again before entering the coating machine. Specifically, the glass cleaned by the cleaning machine waits in the transition area. If the transition area is open to the workshop environment, dust, mosquitoes, and debris in the workshop environment will easily fall onto the glass surface, resulting in the appearance of defective products. Therefore, the clean room is an effective guarantee for improving the quality of glass coating.
[0004] However, the current clean room has the following problems during use: the glass will be dried by hot air at the end of the cleaning machine, but the environment inside the cleaning machine is a hot and humid environment, so a large number of water molecules will still remain on the surface of the glass, especially when the cleaning speed of the cleaning machine is fast, there will even be water droplets remaining on the side of the glass. These water molecules will first be brought into the clean room. In addition, the hot air inside the cleaning machine will also enter the clean room through the entrance of the clean room. In addition, the temperature of the glass itself is high, and the clean room will soon become hot and humid. After measurement, the humidity will exceed 80%, and the hot and humid environment is not conducive to the glass. The evaporation of surface water molecules will eventually adsorb some of them on the glass surface and enter the coating machine. The water molecules entering the coating machine will then enter the vacuum pump and cause the vacuum pump's exhaust efficiency to decrease. In addition, since the Low-E coating line often needs to be inspected, patrolled or troubleshooted, operators need to enter the clean room frequently, and mosquitoes will inevitably enter the clean room through the gap in the clean room door and fall on the glass surface, affecting the coating quality. Usually, lighting lamps will be installed on the top of the clean room. Over time, dust on the lamp tubes will also fall on the glass and affect the coating quality.
[0005] Patent CN115929174A discloses a clean room with an automatic lifting structure and a sealed door. The vertical lifting sealed door structure drives the air flow to be lighter when opening and closing, and dust is not easy to enter the clean room. Patent CN219433396U discloses a clean room with a multi-layer filtering effect. This clean room has a first filter, a clean air chamber and a second filter, which achieves a multi-layer filtering effect on the air input into the clean room. Patent CN220355708U discloses a glass-coated clean room. Through the purification mechanism set on the top, two air purification operations can be achieved to ensure the cleanliness of the air entering the clean room. The above patents only provide solutions to the dust prevention and purification problems of clean rooms, but do not provide solutions to the above problems existing in the current clean rooms of Low-E coating lines during use.

[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] The clean room for the Low-E coating line in the present invention comprises a clean room body, a partition wall is arranged in the clean room body, the clean room body is divided into a wet wind isolation area on the right and an active dehumidification area on the left, a glass inlet channel is arranged on the right wall of the clean room body and a glass outlet channel is arranged on the left wall, a glass passing channel is arranged on the partition wall, a first roller for conveying glass is arranged in the wet wind isolation area and the active dehumidification area, and a mosquito-proof lamp with an installation height lower than the height of the corresponding first roller conveying plane is arranged in both the wet wind isolation area and the active dehumidification area, and a lighting lamp with a positive projection outside the area surrounded by the corresponding first roller is arranged at the top of each of the wet wind isolation area and the active dehumidification area, an exhaust fan and an exhaust fan connected to the air inlet are arranged in the wet wind isolation area, and a dryer and a humidity sensor are arranged in the active dehumidification area; the humidity sensor is connected to the signal input end of the control unit, and the signal output end of the control unit is connected to the exhaust fan, the exhaust fan and the dryer. In this way, the humidity in the active dehumidification area is detected by the humidity sensor and transmitted to the control unit. When the humidity received by the control unit is greater than a set value, the control unit controls the exhaust fan, the exhaust fan and the dryer to start. The exhaust fan can draw the air with higher humidity in the wet wind isolation area near the cleaning machine to the external environment, and the exhaust fan can draw fresh air with lower humidity in the external environment into the wet wind isolation area. Therefore, through the cooperation of the exhaust fan and the exhaust fan, the wet wind isolation area can be replaced with fresh air to reduce the humidity in the wet wind isolation area and the humidity on the glass surface in the wet wind isolation area. In this way, the glass with reduced surface humidity will not significantly increase the humidity in the active dehumidification area after passing through the glass on the isolation wall, through the passage and into the active dehumidification area. The dryer can perform internal circulation drying in the active dehumidification area to reduce the humidity in the active dehumidification area and the humidity on the glass surface in the active dehumidification area. degree, thereby reducing the water vapor entering the vacuum pump in the coating machine, thereby improving the vacuum pump's exhaust efficiency and extending the vacuum pump's maintenance cycle and service life; and because the installation height of the mosquito-proof lamps in the wet wind isolation zone and the active dehumidification zone is lower than the height of the corresponding first roller conveying plane, the height of the mosquitoes captured at the mosquito-proof lamps in the wet wind isolation zone and the active dehumidification zone is lower than the height of the corresponding first roller conveying plane, and the glass is on the conveying plane of the first roller, so the height of the mosquitoes captured at the mosquito-proof lamps in the wet wind isolation zone and the active dehumidification zone is lower than the height of the glass, thereby reducing the probability of mosquitoes falling on the glass surface, thereby improving the yield rate; in addition, because the orthographic projection of the lighting lamps arranged on the top of the wet wind isolation zone and the active dehumidification zone is outside the area surrounded by the corresponding first roller, the probability of dust accumulation on the lamp tubes of the lighting lamps falling on the glass surface can be reduced, thereby improving the yield rate.

In this way, the exhaust fan draws fresh air with lower humidity in the external environment into the wet wind isolation area through the air inlets below the first roller, and the fresh air entering the wet wind isolation area flows from bottom to top and drives the air with higher humidity originally in the wet wind isolation area to flow upward, while the exhaust fans above the first roller draw the air with higher humidity flowing upward in the wet wind isolation area into the external environment. Therefore, by designing the setting positions of the air inlets and exhaust fans, the efficiency of fresh air exchange in the wet wind isolation area can be improved; the replaceable filter can filter out dust in the external environment to prevent dust in the external environment from entering the wet wind isolation area along with the fresh air with lower humidity, and the louver baffle can achieve dustproof and waterproof effects.
[0021] In the present invention, two upper and lower first adjustable windshields are laid on the inner side surface of the right side wall of the clean room body at the position of the glass inlet channel, and the installation height of each first adjustable windshield is adjusted by the first adjusting component, the upper first adjustable windshield is used to block the upper opening of the glass inlet channel, and the lower first adjustable windshield is used to block the lower opening of the glass inlet channel, and the glass inlet channel located in the gap between the upper and lower first adjustable windshields is used as a channel for glass to enter the clean room body; two upper and lower second adjustable windshields are laid on the left side surface of the isolation wall at the position of the glass passing through the channel, and the installation height of each second adjustable windshield is adjusted by the second adjusting component, the upper second adjustable windshield is used to block the upper opening of the glass passing through the channel, and the lower second adjustable windshield is used to block the lower opening of the glass passing through the channel, and the glass passing through the channel located in the gap between the upper and lower second adjustable windshields is used as a channel for glass to pass through the isolation wall. In this way, according to the thickness of the glass, by adjusting the gap between the upper and lower two first adjustable wind shields and by adjusting the gap between the upper and lower two second adjustable wind shields, the glass with thickness varying within a certain range can pass through the gap between the upper and lower two first adjustable wind shields and the gap between the upper and lower two second adjustable wind shields in turn to enter the active dehumidification zone, and when the glass passes through the glass inlet channel at the gap between the upper and lower two first adjustable wind shields, the wind-shielding effect of the upper and lower two first adjustable wind shields can prevent the air carrying dust in the external environment from entering the wet wind isolation zone through the glass inlet channel, and when the glass passes through the glass passing channel at the gap between the upper and lower two second adjustable wind shields, the wind-shielding effect of the upper and lower two second adjustable wind shields can prevent the air with high humidity in the wet wind isolation zone from entering the active dehumidification zone through the glass passing channel.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0033] like Figure 1-Figure 5 As shown, a clean room for a Low-E coating line, a cleaning machine 1 is provided on the right side of the clean room and a coating machine 2 is provided on the left side, the clean room comprises a clean room body 3, a partition wall 4 is provided in the clean room body 3, the clean room body 3 is divided into a wet wind isolation area 5 on the right side and an active dehumidification area 6 on the left side, a glass inlet channel 7 is provided on the right wall of the clean room body 3 and a glass outlet channel 8 is provided on the left wall, a glass passing channel 9 is provided on the partition wall 4, a first roller 10 for conveying glass 28 is provided in both the wet wind isolation area 5 and the active dehumidification area 6, and both are provided with a low installation height A mosquito-proof lamp 11 is provided at the height of the conveying plane of the corresponding first roller 10, and lighting lamps whose projections are outside the area surrounded by the corresponding first roller 10 are provided at the top of the wet wind isolation area 5 and the active dehumidification area 6. An exhaust fan 12 and an exhaust fan connected to the air inlet 13 are provided in the wet wind isolation area 5. A dryer 14 is provided in the active dehumidification area 6 and a humidity sensor 15 is provided near the glass outlet channel 8; the humidity sensor 15 is connected to the signal input end of the control unit, and the signal output end of the control unit is connected to the exhaust fan 12, the exhaust fan and the dryer 14.
[0034] In this way, the humidity in the active dehumidification area 6 near the glass outlet channel 8 is detected by the humidity sensor 15 and transmitted to the control unit. When the humidity received by the control unit is greater than a certain set value, the control unit controls the exhaust fan 12, the exhaust fan and the dryer 14 to start, wherein the exhaust fan 12 can draw the air with higher humidity in the wet wind isolation area 5 near the cleaning machine 1 to the external environment, and the exhaust fan can draw the fresh air with lower humidity in the external environment into the wet wind isolation area 5. Therefore, through the cooperation of the exhaust fan 12 and the exhaust fan, the wet wind isolation area 5 can be replaced with fresh air to reduce the humidity in the wet wind isolation area 5 and reduce the humidity on the surface of the glass 28 in the wet wind isolation area 5. In this way, the glass 28 with reduced surface humidity will not significantly increase the humidity in the active dehumidification area 6 after passing through the glass on the isolation wall 4, through the channel 9 and entering the active dehumidification area 6. The dryer 14 can perform internal circulation drying in the active dehumidification area 6 to reduce the humidity in the active dehumidification area 6 and reduce the humidity on the surface of the glass 28 in the active dehumidification area 6. The humidity on the surface of the glass 28 can be reduced, thereby reducing the water vapor entering the vacuum pump in the coating machine 2, thereby improving the vacuum pump's exhaust efficiency and extending the maintenance cycle and service life of the vacuum pump; and because the installation height of the mosquito-proof lamps 11 in the wet wind isolation zone 5 and the active dehumidification zone 6 is lower than the height of the conveying plane of the corresponding first roller 10, the mosquitoes captured at the mosquito-proof lamps 11 in the wet wind isolation zone 5 and the active dehumidification zone 6 are at a height lower than the height of the conveying plane of the corresponding first roller 10, and the glass 28 is at the first roller 10. 0, so that the height of the mosquitoes captured at the mosquito-proof lamp 11 in the wet wind isolation zone 5 and the active dehumidification zone 6 is lower than the height of the glass 28, thereby reducing the probability of mosquitoes falling on the surface of the glass 28, thereby improving the yield rate; in addition, because the positive projection of the lighting lamp arranged on the top of the wet wind isolation zone 5 and the active dehumidification zone 6 is outside the area surrounded by the corresponding first roller 10, this can reduce the probability of dust accumulation on the lighting lamp tube falling on the surface of the glass 28, thereby improving the yield rate.
[0035] Among them, the positions of the glass passing channel 9, the glass inlet channel 7 and the glass outlet channel 8 are corresponding, the conveying plane of the first roller 10 in the wet wind isolation zone 5 is flush with the conveying plane of the first roller 10 in the active dehumidification zone 6, and the conveying direction of the first roller 10 in the wet wind isolation zone 5 and the active dehumidification zone 6 are both from right to left.
[0036] In one embodiment, there are multiple air inlets 13, some of which are opened on the front side wall of the wet wind isolation zone 5, and the remaining air inlets 13 are opened on the rear side wall of the wet wind isolation zone 5, and each air inlet 13 is located below the first roller conveyor 10 in the wet wind isolation zone 5, and a replaceable filter is installed at each air inlet 13; there are multiple exhaust fans 12, some of which are arranged on the front side wall of the wet wind isolation zone 5, and the remaining exhaust fans 12 are arranged on the rear side wall of the wet wind isolation zone 5, and each exhaust fan 12 is located above the first roller conveyor 10 in the wet wind isolation zone 5, and each exhaust fan 12 is provided with a louver baffle.
[0037] In this way, the exhaust fan draws fresh air with lower humidity in the external environment into the wet wind isolation area 5 through the air inlets 13 below the first roller 10, and the fresh air entering the wet wind isolation area 5 flows from bottom to top and drives the air with higher humidity originally in the wet wind isolation area 5 to flow upward, while the exhaust fans 12 above the first roller 10 draw the air with higher humidity flowing upward in the wet wind isolation area 5 into the external environment. Therefore, by designing the setting positions of the air inlets 13 and the exhaust fans 12, the efficiency of fresh air exchange in the wet wind isolation area 5 can be improved; and the replaceable filter can filter out dust in the external environment to prevent dust in the external environment from entering the wet wind isolation area 5 along with the fresh air with lower humidity, and the louver baffle can achieve dustproof and waterproof effects.
[0038] In one embodiment, Figure 1 and Figure 3 As shown, two upper and lower first adjustable windshield plates 16 are laid on the inner side surface of the right side wall of the clean room body 3 at the position of the glass inlet channel 7, and the installation height of each first adjustable windshield plate 16 is adjusted by a first adjustment component. The upper first adjustable windshield plate 16 is used to shield the upper opening of the glass inlet channel 7, and the lower first adjustable windshield plate 16 is used to shield the lower opening of the glass inlet channel 7. The glass inlet channel 7 at the gap between the upper and lower first adjustable windshield plates 16 is used as a channel for the glass 28 to enter the clean room body 3; as shown Figure 1 and Figure 4 As shown, two upper and lower second adjustable wind shields 18 are laid on the left side surface of the isolation wall 4 at the position of the glass passing through the channel 9, and the installation height of each second adjustable wind shield 18 is adjusted by a second adjustment component. The upper second adjustable wind shield 18 is used to block the upper opening of the glass passing through the channel 9, and the lower second adjustable wind shield 18 is used to block the lower opening of the glass passing through the channel 9. The glass passing channel 9 in the gap between the upper and lower second adjustable wind shields 18 is used as a channel for the glass 28 to pass through the isolation wall 4.
[0039] In this way, according to the thickness of the glass 28, by adjusting the gap between the upper and lower two first adjustable wind shields 16 and by adjusting the gap between the upper and lower two second adjustable wind shields 18, the glass 28 with a thickness varying within a certain range can pass through the gap between the upper and lower two first adjustable wind shields 16 and the gap between the upper and lower two second adjustable wind shields 18 in sequence to enter the active dehumidification zone 6, and when the glass 28 passes through the glass inlet channel 7 at the gap between the upper and lower two first adjustable wind shields 16, the wind-shielding effect of the upper and lower first adjustable wind shields 16 can prevent the air carrying dust in the external environment from entering the wet wind isolation zone 5 through the glass inlet channel 7, and when the glass 28 passes through the glass passing channel 9 at the gap between the upper and lower two second adjustable wind shields 18, the wind-shielding effect of the upper and lower second adjustable wind shields 18 can prevent the air with high humidity in the wet wind isolation zone 5 from entering the active dehumidification zone 6 through the glass passing channel 9.
[0040] Preferably, the first adjusting component is a first adjusting screw 17 ; and the second adjusting component is a second adjusting screw 19 .
[0041] In one embodiment, Figure 2 and Figure 4 As shown, the right side of the isolation wall 4 is provided with limit columns 20 at the front and rear ends of the glass passing channel 9, and each limit column 20 is fixed at a corresponding position of the inner bottom wall of the wet wind isolation area 5. In this way, the front and rear limit columns 20 cooperate to limit the glass 28 being transported, so that the glass 28 can always be transported horizontally from right to left.
[0042] In one embodiment, Figure 1 and Figure 2 As shown, a defective glass delivery channel 21 is provided on the front side wall of the active dehumidification zone 6, and a sealing door 22 is hingedly connected to the outer surface of the front side wall of the active dehumidification zone 6 at the position of the defective glass delivery channel 21 through a hinge 23. Figure 3-Figure 5 The sealing door 22 opens downward and is used to open the defective glass delivery channel 21, and the sealing door 22 closes upward and is used to close the defective glass delivery channel 21. A second roller for conveying glass 28 is also provided in the active dehumidification area 6. The conveying direction of the second roller is from back to front, and the second roller is driven by a lifting assembly to vertically lift and lower relative to the corresponding first roller 10 in the active dehumidification area 6, so as to realize alternating operation with the corresponding first roller 10.
[0043] In this way, when the glass 28 in the active dehumidification zone 6 is defective glass 28, the second roller is driven to rise vertically relative to the corresponding first roller 10 through the lifting assembly, so that the defective glass 28 on the conveying plane of the first roller 10 falls on the conveying plane of the second roller, and then the sealing door 22 is opened and the defective glass 28 is conveyed forward by the second roller and conveyed to the outside of the clean room body 3 through the defective glass delivery channel 21.
[0044] In one embodiment, the humidity sensor 15 is used to detect the humidity in the active dehumidification zone 6 near the glass outlet channel 8 and transmit it to the control unit.
