At the same time, the inclination angle of the glass plate can be reduced to prevent the glass plate from tipping over. By using the second ventilation pipe, the second electric valve and the equipment program in conjunction with each other, the surface of the glass plate can be ventilated and dried while being inflated for protection, thereby increasing the air flow rate, avoiding water vapor remaining on the surface of the glass plate, improving the ventilation efficiency, and preventing the glass plate from getting damp and mildewing.

[0034] The first electric fan 24 is arranged on one side of the outside of the glass plate fume hood 1, and the second electric fan 25 is arranged on the other side of the outside of the glass plate fume hood 1. The two sets of electric fans are used to cooperate in ventilation operation;

The air compressor 31 is detachably mounted at the other end of the glass plate fume hood 1. The air compressor 31 is externally connected to a ventilation hose connected to the first ventilation pipe 17. Several groups of placement slots 32 are disposed within the glass plate fume hood 1, between the four groups of partition plates 14, for securing the glass plates. Several groups of second pressure sensors 321 are detachably mounted in the groups of placement slots 32 for detecting the weight of the glass plates.

[0036] Several groups of second ventilation pipes 33 are installed at intervals inside the glass plate fume hood 1, located between the several groups of placement slots 32, and the several groups of second ventilation pipes 33 are connected to the first ventilation pipes 17, for ventilating and drying the surface of the glass plate;

[0039] The glass plate fume hood 1 is powered by an external workshop power supply to drive the internal components to operate;

[0040] The glass plate fume hood 1 is also equipped with a device program that can control the operation of the two sets of electric fans, the start and stop of the air compressor 31, the opening and closing of the first electric valve 34, and the opening and closing of the second electric valve 35;

[0041] The three groups of humidity sensors, the two groups of electric fans, the air compressor 31, the first electric valve 34, the second electric valve 35, and the two groups of pressure sensors are all connected to the device program signal.

[0042] Cabinet ventilation operation:

[0043] After the glass plates are processed, the staff need to place them in the workshop for subsequent packaging and transportation. The staff first use the handling tools to transport the glass plates to the glass plate fume hood 1, and then open the door of the glass plate fume hood 1 and the workshop power supply. At this time, the glass plate fume hood 1 is started, the equipment program is started, and the staff transports the glass plates in turn and places them in the placement slots 32. After placement, the staff closes the door. At this time, the equipment program detects the humidity value in the glass plate fume hood 1 through three sets of humidity sensors and compares it with the set value. The equipment program sets the humidity value to A1, A2, and A3, where A1 is the minimum value and A3 is the maximum value. It can be adjusted according to the specific humidity. The speeds of the two sets of electric fans are B1, B2, and B3, with B1 being the minimum and B3 being the maximum. These can be adjusted according to specific needs. When the device program detects that the humidity value of the three sets of humidity sensors is A1, the device program determines that the interior of the glass plate fume hood 1 is dry and only ventilation operation is required. The device program controls the first electric fan 24 to start in forward rotation and the second electric fan 25 to start in reverse rotation, both with a speed of B1. The first electric fan 24 first draws the air from the top of the workshop into the glass plate fume hood 1, and then the second electric fan 25 discharges the air in the glass plate fume hood 1 into the production workshop, performing a circulating ventilation operation on the stored glass plates.

[0044] When the device program detects that the humidity value of the three sets of humidity sensors is A2, the device program determines that the humidity inside the glass plate fume hood 1 has increased and a drying operation is required. The device program controls the speed of the two sets of electric fans to be adjusted to B2. The first electric fan 24 first draws air from the top of the workshop into the glass plate fume hood 1, and then the second electric fan 25 discharges the air in the glass plate fume hood 1 into the production workshop. The speed of the two sets of electric fans is increased to speed up the air circulation and ventilate and dry the stored glass plates.

[0045] When the device program detects that the humidity value of the three sets of humidity sensors is A3, the device program determines that the humidity inside the glass plate fume hood 1 is high and a drying operation is required. The device program controls the speed of the two sets of electric fans to be adjusted to B3. The first electric fan 24 first draws air from the top of the workshop into the glass plate fume hood 1, and then the second electric fan 25 discharges the air in the glass plate fume hood 1 into the production workshop. The speed of the two sets of electric fans is increased to speed up the air circulation and ventilate and dry the stored glass plates.

[0046] During the above operation, the device program controls the dehumidification operation. The device program detects the weight of the activated carbon dehumidification block 23 through the first pressure sensor 225 and compares it with the set value. The device program sets the weight values ​​to C1 and C2, where C1 is the minimum value and C2 is the maximum value. The values ​​can be adjusted according to specific needs. When the device program detects the weight value to be C1, the device program determines that the interior of the glass plate fume hood 1 is dry and the activated carbon dehumidification block 23 absorbs little water vapor, and the device program does not operate.

[0047] When the device program detects that the weight value is C2, the device program determines that the bottom of the glass plate fume hood 1 is damp, the activated carbon dehumidification block 23 absorbs a lot of water vapor, and the weight of the activated carbon dehumidification block 23 increases. At this time, the activated carbon dehumidification block 23 that becomes heavier after absorbing water will press down the placement frame 224 and drive the second connecting rod 222 to rotate along the rotating shaft 221. The second connecting rod 222 drives the placement frame 224 at one end to move downward, and the second connecting rod 222 drives the third connecting rod 223 at the other end to move upward. The third connecting rod 223 drives the two groups of third connecting rods 224 to move downward. A connecting rod 212 is in operation, and the two sets of first connecting rods 212 drive the three sets of ventilation blades 211 to rotate and open the ventilation valve 21. The equipment program controls the two sets of electric fans to rotate forward, and the speed is adjusted to B3. The two sets of electric fans quickly draw air from the top of the workshop into the glass plate fume hood 1, and then discharge it to the outside through the ventilation valve 21, discharging the humid air accumulated at the bottom of the glass plate fume hood 1 to the outside, ventilating and drying the bottom of the stored glass plates to prevent moisture from being adsorbed on the bottom of the glass plates and affecting subsequent packaging and transportation;

[0048] During the ventilation and drying process, the wet activated carbon dehumidification block 23 can be air-dried to accelerate the discharge of water vapor. The weight of the dried activated carbon dehumidification block 23 becomes lighter. At this time, the second connecting rod 222 rotates along the rotating shaft 221 and drives the placement frame 224 to rise upward. The second connecting rod 222 drives the third connecting rod 223 to move downward. The third connecting rod 223 drives the two groups of first connecting rods 212 to operate. The two groups of first connecting rods 212 drive the three groups of ventilation blades 211 to rotate and close the ventilation valve 21. Then, the device program controls the two groups of fans to reset according to the above set value to complete the ventilation operation.

[0049] By using two sets of electric fans, three sets of humidity sensors and equipment programs in conjunction with each other, the ventilation and drying speed can be changed according to the different dryness and humidity levels inside the glass plate fume hood 1. At the same time, the dryness and humidity levels of different areas inside the glass plate fume hood 1 can be detected. When the humidity is low, circulating ventilation operations are performed to reduce energy consumption and reduce factory costs. When the humidity is high, the air circulation speed is increased to prevent the glass plates from being deformed by moisture during storage. By using the activated carbon dehumidification block 23, the first pressure sensor 225 and the equipment program in conjunction with each other, the bottom of the glass plate fume hood 1 can be dehumidified and dried to prevent water vapor from being adsorbed on the bottom of the glass plate and affecting subsequent packaging and transportation. At the same time, the dead weight of the activated carbon dehumidification block 23 is used to drive the ventilation valve 21 to open and change the ventilation direction, so that the humid air accumulated at the bottom of the glass plate fume hood 1 is quickly discharged to the outside. No additional ventilation equipment is required, energy consumption is reduced, and the effect of energy saving and emission reduction is achieved. In addition, the wet activated carbon dehumidification block 23 can be ventilated and dehumidified to reduce the drying time of the activated carbon dehumidification block 23. There is no need to frequently disassemble it for dehumidification, thereby improving the factory's production efficiency and reducing the burden on staff.

[0050] Glass panel ventilation operation:

[0051] During the above operation, the equipment program controls the ventilation operation of the glass plate. After the glass plate is placed, the staff detects the weight of the glass plate through the second pressure sensor 321 and compares it with the set value. The equipment program sets the weight values ​​as X1, X2, and X3, with X1 being the minimum value and X3 being the maximum value, which can be adjusted according to specific needs. The pumping values ​​of the air compressor 31 are Y1, Y2, and Y3, with Y1 being the minimum value and Y3 being the maximum value, which can be adjusted according to specific needs. When the equipment program detects that the weight value of the second pressure sensor 321 is X1, the equipment program determines that the glass plate is light and no additional protective operation is required. Only the protective air cushion 16 is used for protection, and the equipment program does not perform any operation.

[0052] When the device program detects that the weight value of the second pressure sensor 321 is X2, the device program determines that the weight of the glass sheet has increased and a protective operation is required. The device program controls the air compressor 31 to start, the pumping value is Y1, the first electric valve 34 is open, and the second electric valve 35 is closed. The air compressor 31 pumps air into the first ventilation pipe 17 and then transports air to each group of protective air cushions 16. After the protective air cushions 16 are inflated, they expand to prevent the glass sheet from directly contacting the spacer 14 and causing damage. At the same time, they can reduce the tilt angle of the glass sheet to prevent the glass sheet from tipping over.

[0053] When the device program detects that the weight value of the second pressure sensor 321 is X3, the device program determines that the glass sheet is heavy and needs additional protection. The device program controls the air compressor 31 to adjust the pumping value to Y2, the first electric valve 34 is opened, and the second electric valve 35 is closed. The air compressor 31 pumps air into the first ventilation pipe 17 and then transports air to each group of protective air cushions 16. After the protective air cushions 16 are inflated, they expand to prevent the glass sheet from directly contacting the spacer 14 and causing damage. At the same time, the tilt angle of the glass sheet can be reduced to prevent the glass sheet from tipping over.

[0054] After completing the above-mentioned pumping operation, the device program controls the first electric valve 34 to close, eliminating the need for frequent pumping operations and reducing energy consumption;

[0055] During the above operation, when the device program detects a humidity value of A3 through the three groups of humidity sensors, the device program controls the air compressor 31 to start, the pumping air value is Y3, the second electric valve 35 is open, and the first electric valve 34 is closed. The air compressor 31 pumps air into the first ventilation pipe 17 and then sprays air from each group of second ventilation pipes 33 onto the surface of the glass plate, directly ventilating and drying the surface of the glass plate, increasing the air flow rate and preventing moisture from remaining on the surface of the glass plate.

[0056] By using the second pressure sensor 321, the air compressor 31, the protective air cushion 16 in conjunction with the equipment program, the protection mode can be changed according to the weight of the glass plate. When the glass plate is light, only the protective air cushion 16 body is used for protection operation to avoid collision between the glass plate and the partition plate 14, thereby reducing energy consumption. When the glass plate is heavy, the inflation amount of the protective air cushion 16 is changed to change the expansion degree to avoid direct contact between the glass plate and the partition plate 14, thereby causing damage. At the same time, the inclination angle of the glass plate can be reduced to prevent the glass plate from tipping over. By using the second ventilation pipe 33, the second electric valve 35 in conjunction with the equipment program, the surface of the glass plate can be ventilated and dried while inflating for protection, thereby increasing the air flow rate, avoiding water vapor from remaining on the surface of the glass plate, improving the ventilation efficiency, and preventing the glass plate from getting damp and mildewing.
