Description

Technical Field

[0001] The present invention relates to the field of glass processing, and in particular to a glass substrate swing amount detection control system, method, equipment and storage medium. Background Art

[0002] In the production line of optoelectronic display glass substrates, the glass ribbon produced from the furnace is still in a high temperature state after being cut. It needs to be cooled down by the lower room temperature of the cutting workshop before entering the darkroom for defect detection. The darkroom is an equipment area with a light source to initially check whether the surface of the glass substrate has defects. Therefore, a narrow gap with a small width is set at the connection between the darkroom and the cutting workshop for the glass substrate to pass through, so as to prevent the light from the cutting workshop from entering the darkroom and affecting the detection effect.

[0003] When transporting the glass substrate from the cutting workshop to the darkroom, the glass substrate is usually fixed by clamping the glass invalid area at the upper end of the glass substrate and the waste area at the rear end to achieve transportation. Since the glass substrate is large in size and thin in thickness (generally less than 0.5mm), and the lower end of the glass substrate close to the ground is suspended, it is easy to swing due to the change of wind pressure on both sides of the glass substrate during transportation, so that the surface of the glass substrate is scratched or collided with the wall or external mechanical equipment due to excessive swinging during the narrow gap, resulting in damage or even breakage of the glass substrate, affecting product quality and yield rate.

[0004] In the prior art, operators usually visually inspect the distance between the glass substrate and the wall or external equipment. When there is a risk of scratching, the swing amplitude of the glass substrate is reduced by reducing the air conditioning wind in the room. However, this will cause the indoor temperature to rise, which will slow down the cooling speed of the glass substrate, which is not conducive to the molding of the glass substrate and easily leads to the waste of semi-finished glass substrates. In addition, the manual visual inspection method has a large error and cannot guarantee the stability of the quality of the glass substrate. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] like Figures 1 to 5 As shown, in the first embodiment of the present invention, the glass substrate swing detection and control system 100 includes at least two fans 110 , a glass substrate swing adjustment mechanism 120 , a displacement sensor 130 , and a control device 140 .

[0033] The fans 110 are arranged in pairs on both sides of the plane formed by the glass substrate 200 . The glass substrate swing adjustment mechanism 120 includes one or more of the following: a fan moving mechanism 121 and a fan frequency adjustment mechanism 122 .

[0034] The fan moving mechanism 121 is connected to the fan 110, and can drive the fan 110 located on one side or both sides of the plane formed by the glass substrate 200 to move closer to or away from the glass substrate 200; the fan frequency adjustment mechanism 122 is electrically connected to the fan 110, and is used to adjust the frequency of the fan 110 located on one side or both sides of the plane formed by the glass substrate 200.

[0035] The detection end of the displacement sensor 130 faces the surface of the glass substrate 200. The displacement sensor 130 is used to detect the swing amount of the glass substrate 200 and the target position C2 and generate a swing amount electrical signal. The control device 140 is connected to the displacement sensor 130 for communication and is electrically connected to the glass substrate swing adjustment mechanism 120. The control device 140 is used to control the frequency of the fan 110 and / or the distance between the fan 110 and the glass substrate 200 according to the swing amount electrical signal.

[0036] In the embodiment of the present invention, the target position C2 is as follows: Figure 5 As shown, the displacement sensor 130 located at the central axis of the narrow gap C1 can detect the swing amount of the glass substrate 200 and the target position C2, and send the swing amount electrical signal to the control device 140, so that the control device 140 can determine whether the swing amplitude of the glass substrate 200 is too large according to the swing amount electrical signal, and reduce the swing amplitude of the glass substrate 200 by at least one of the following methods when the swing amplitude of the glass substrate 200 is too large: The fan frequency adjustment mechanism 122 is controlled to adjust the frequency of the fans 110 located at both sides of the glass substrate 200 , and the fan moving mechanism 121 is controlled to adjust the distance between the fans 110 located at both sides of the glass substrate 200 and the glass substrate 200 .

[0037] The air outlet of the fan 110 in the embodiment of the present invention faces the ground, that is, the airflow generated by the fan 110 flows along the surfaces of both sides of the glass substrate 200. Therefore, by adjusting the frequency of the fan 110 and / or adjusting the distance between the fan 110 and the glass substrate 200, the pressure difference on both sides of the glass substrate 200 can be changed, thereby changing the magnitude of the force on both sides of the glass substrate 200, so as to reduce the swing amplitude of the glass substrate 200.

[0038] Specifically, when the glass substrate 200 is biased toward the wall on one side, the force acting on the glass substrate 200 can be adjusted by at least one, two or more of the following methods: The frequency of the fan 110 on this side (i.e., the side where the glass substrate 200 is biased toward the wall) is controlled to decrease, the fan 110 on this side is controlled to be away from the glass substrate 200, the frequency of the fan 110 on the other side is controlled to increase, and the fan 110 on the other side is controlled to be close to the glass substrate 200. By changing the pressure difference on both sides of the glass substrate 200, the force acting on the surface of the glass substrate 200 closer to the wall toward the target position C2 is increased, thereby reducing the swing amount of the glass substrate 200, thereby preventing the glass substrate 200 from being scratched when passing through the narrow gap C1.

[0039] The fans 110 in this embodiment may be one pair, two pairs, or multiple pairs. The paired fans 110 are respectively arranged on both sides of the glass substrate 200, and each pair of fans 110 are arranged opposite to each other to ensure that the force application areas of each pair of fans 110 on both sides of the glass substrate 200 are the same.

[0040] In the embodiment of the present invention, the glass substrate swing amount detection and control system 100 can detect the swing amount of the glass substrate 200, determine whether the swing amplitude of the glass substrate 200 is too large, and accurately adjust the wind pressure on both sides of the glass substrate 200 by controlling the power of the fans 110 located on both sides of the glass substrate 200 and / or the distance between the fans 110 and the glass substrate 200, so that the swing amount of the glass substrate 200 is within a safe range, thereby avoiding scratches on the glass substrate 200 and improving the yield rate of the glass substrate 200. At the same time, the fans 110 can cooperate with the indoor air conditioner to further accelerate the cooling speed of the glass substrate 200, thereby improving the cooling effect.

[0041] like Figure 4 and Figure 6 As shown, in some embodiments, the fan moving mechanism 121 includes a track assembly 1211 , at least two connecting and fixing plates 1212 , and at least two driving members 1213 .

[0042] Each fan 110 is movably connected to the track assembly 1211 via at least one connecting and fixing plate 1212. The driving member 1213 is disposed on the corresponding connecting and fixing plate 1212 and is transmission-connected to the track assembly 1211. The driving member 1213 can drive the corresponding connecting and fixing plate 1212 to drive the corresponding fan 110 to approach or move away from the glass substrate 200 along the extension direction of the track assembly 1211.

[0043] In this embodiment, the track assembly 1211 is fixed to an external device or a ceiling, and the connecting fixing plate 1212 connects the fan 110 to the track assembly 1211. The control device 140 can control the driving member 1213 to drive the connecting fixing plate 1212 to reciprocate along the extension direction of the track assembly 1211, so as to drive the fan 110 to approach or move away from the glass substrate 200, thereby adjusting the distance between the fan 110 and the glass substrate 200.

[0044] Each fan 110 is connected to the track assembly 1211 via a connecting fixing plate 1212, and the distance between the fan 110 and the glass substrate 200 is adjusted via a corresponding driving member 1213. The driving member 1213 may be a driving motor.

[0045] like Figure 4 , Figure 6 and Figure 7 As shown, further, the track assembly 1211 includes at least one guide rail 1211A, at least two sliders 1211B, at least two transmission gears 1211C and at least one rack 1211D. The guide rail 1211A and the rack 1211D are fixedly arranged on the outside, and the slider 1211B is slidably arranged on the guide rail 1211A and slidably connects the corresponding connecting and fixing plate 1212 with the guide rail 1211A.

[0046] The driving end of the driving member 1213 is connected to the corresponding transmission gear 1211C, and the transmission gear 1211C is meshed with the rack 1211D. The driving member 1213 can drive the transmission gear 1211C to reciprocate along the extension direction of the rack 1211D to drive the corresponding fan 110 to approach or move away from the glass substrate 200 along the extension direction of the rack 1211D.

[0047] In this embodiment, a pair of fans 110 located on both sides of the glass substrate 200 are connected to one or more sliders 1211B through a connecting and fixing plate 1212, and the sliders 1211B are slidably arranged on the same guide rail 1211A. When the driving end of the driving member 1213 rotates, the transmission gear 1211C can reciprocate along the extension direction of the rack 1211D, so that the fan 110 is close to or away from the glass substrate 200.

[0048] like Figure 8 and Fig. 9 As shown, specifically, grooves A1 are provided on both side surfaces of the guide rail 1211A, and a plurality of ball bearing portions B1 are provided on the surface of the slider 1211B facing the guide rail 1211A. When the slider 1211B is connected to the guide rail 1211A, the ball bearing portions B1 are located in the grooves A1, so that the slider 1211B can slide along the guide rail 1211A.

[0049] Furthermore, the extending directions of the guide rail 1211A and the rack 1211D are perpendicular to the surface of the glass substrate 200 in a stationary state.

[0050] When the glass substrate 200 is at the target position C2, the glass substrate 200 is perpendicular to the ground. At this time, the extension direction of the guide rail 1211A and the rack 1211D is perpendicular to the surface of the glass substrate 200, that is, perpendicular to the central axis of the narrow gap C1, and the guide rail 1211A and the rack 1211D are arranged in parallel.

[0051] If the extension direction of the guide rail 1211A and the rack 1211D is inclined with respect to the central axis of the narrow gap C1, when the fans 110 on both sides of the glass substrate 200 approach or move away from the glass substrate 200 respectively, due to the different spacings between each pair of fans 110 and the glass substrate 200, the pressure difference generated by the two fans 110 forms a force applied to different areas of the glass substrate 200, and it is impossible to achieve precise control of the force acting on the glass substrate 200.

[0052] Therefore, by arranging the extension direction of the guide rail 1211A and the rack 1211D to be perpendicular to the central axis of the narrow gap C1, the force generated by the pressure difference produced by each pair of fans 110 is always located in the same area of ​​the glass substrate 200, so as to ensure precise control of the force on the glass substrate 200.

[0053] like Figure 1 As shown, in some embodiments, the control device 140 includes a conversion module 141 and a calculation controller 142 , and the conversion module 141 is communicatively connected with the calculation controller 142 and the displacement sensor 130 .

[0054] The conversion module 141 is used to receive the swing amount electrical signal generated by the displacement sensor 130 , so that the swing amount electrical signal is converted into position information, and the position information is sent to the calculation controller 142 .

[0055] In this embodiment, the conversion module 141 is used to convert the electrical signal generated by the displacement sensor 130 into position information data, so that the calculation controller 142 can obtain the swing amount of the glass substrate 200 .

[0056] Specifically, the displacement sensor 130 in this embodiment can be a laser displacement sensor 130, an ultrasonic displacement sensor 130, or the like, which can measure the swing amount of the glass substrate 200 without contacting the glass substrate 200, so as to avoid scratching the glass substrate 200. The conversion module 141 includes a signal processing circuit to process the electrical signal generated by the displacement sensor 130, eliminate noise, and convert it into position information data.

[0057] In the first embodiment of the present invention, the computing controller 142 is electrically connected to the fan moving mechanism 121 and the fan frequency adjustment mechanism 122. The computing controller 142 is used to receive position information and determine whether the position of the glass substrate 200 is within the target area C3 based on the position information. The target position C2 is located at the center of the target area C3.

[0058] When the position of the glass substrate 200 is able to be located outside the target area C3, the calculation controller 142 calculates a first swing amount between one side surface of the glass substrate 200 and the target position C2, and a second swing amount between the other side surface and the target position C2, and determines the swing direction of the glass substrate 200 based on the first swing amount and the second swing amount.

[0059] The computing controller 142 can control the fan frequency adjustment mechanism 122 to reduce the frequency of the fan 110 located on one side of the swing direction of the glass substrate 200, and / or increase the frequency of the fan 110 located on the other side of the glass substrate 200 according to the swing direction, so that the glass substrate 200 moves to the target position C2 and returns to the target area C3.

[0060] The computing controller 142 can also control the fan moving mechanism 121 to drive the fan 110 located on one side of the swing direction of the glass substrate 200 away from the glass substrate 200, and / or drive the fan 110 located on the other side of the glass substrate 200 to approach the glass substrate 200, so that the glass substrate 200 moves toward the target position C2 and is restored to the target area C3.

[0061] In this embodiment, the computing controller 142 can adjust the pressure difference on both sides of the glass substrate 200 by controlling the frequency of the fan 110, can also adjust the pressure difference on both sides of the glass substrate 200 by controlling the distance between the fan 110 and the glass substrate 200, or can also adjust the pressure difference on both sides of the glass substrate 200 by controlling the frequency of the fan 110 and controlling the distance between the fan 110 and the glass substrate 200 at the same time, thereby moving the glass substrate 200 to the target position C2 and restoring it to the target area C3.

[0062] In the second embodiment of the present invention, the computing controller 142 is electrically connected to the fan moving mechanism 121 and the fan frequency adjustment mechanism 122. The computing controller 142 is used to receive position information and determine whether the position of the glass substrate 200 is within the target area C3 based on the position information. The target position C2 is located at the center of the target area C3.

[0063] When the position of the glass substrate 200 is able to be located outside the target area C3, the calculation controller 142 calculates a first swing amount between one side surface of the glass substrate 200 and the target position C2, and a second swing amount between the other side surface and the target position C2, and determines the swing direction of the glass substrate 200 based on the first swing amount and the second swing amount.

[0064] The computing controller 142 can control the fan frequency adjustment mechanism 122 to reduce the frequency of the fan 110 located on one side of the swing direction of the glass substrate 200, and / or increase the frequency of the fan 110 located on the other side of the glass substrate 200 according to the swing direction, so that the glass substrate 200 moves to the target position C2 and returns to the target area C3.

[0065] After adjusting the frequency of the fan 110 on one side of the glass substrate 200 to the maximum value and the frequency of the fan 110 on the other side to the minimum value, the computing controller 142 obtains the position information again. If the glass substrate 200 can still be located outside the target area C3, the computing controller 142 controls the fan 110 located on one side of the swing direction of the glass substrate 200 to move away from the glass substrate 200 and / or controls the fan 110 located on the other side of the glass substrate 200 to move closer to the glass substrate 200 according to the swing direction, so that the glass substrate 200 moves toward the target position C2 and is relocated to the target area C3.

[0066] In this embodiment, the calculation controller 142 first adjusts the pressure difference between the two sides of the glass substrate 200 by controlling the frequency of the fan 110 , and applies a force toward the target position C2 to the glass substrate 200 . If the swing amount of the glass substrate 200 is still too large after the frequency of the fan 110 on one side of the glass substrate 200 is adjusted to the maximum value and the frequency of the fan 110 on the other side is adjusted to the minimum value, that is, the glass substrate 200 can still be located outside the target area C3, and the swing amount of the glass substrate 200 cannot be adjusted only by adjusting the frequency of the fan 110, then the distance between the fans 110 on both sides of the glass substrate 200 and the glass substrate 200 is controlled so that the fan 110 on one side of the swing direction of the glass substrate 200 is away from the glass substrate 200 and / or the fan 110 on the other side of the glass substrate 200 is controlled to be close to the glass substrate 200, so that the glass substrate 200 moves to the target position C2 and is relocated in the target area C3, so as to realize the progressive control of the swing amount of the glass substrate 200 and improve the control accuracy of the swing amplitude of the glass substrate 200.

[0067] Among them, Figure 5 As shown, the swing direction of the glass substrate 200 is the direction in which the glass substrate 200 approaches the wall on one side. When the glass substrate 200 swings toward the right, the swing direction is toward the right, and when the glass substrate 200 swings toward the left, the swing direction is toward the left.

[0068] Specifically, the fan frequency adjustment mechanism 122 in this embodiment can be a PID (Proportion Integration Differentiation) controller. Each fan 110 is controlled by a corresponding PID controller to adjust the frequency of the fan 110. The glass substrate swing amount detection control system 100 of this embodiment further includes a control cabinet 160, and the fan frequency adjustment mechanism 122 and the conversion module 141 are arranged in the control cabinet 160.

[0069] As Figure 5 、 Figure 6 and 10 shown, for example, a pair of fans 110 includes a first fan 111 and a second fan 112. The first fan 111 is located on one side of the first surface 201 of the glass substrate 200, and the second fan 112 is located on one side of the second surface 202 of the glass substrate 200. The position signal detected by the displacement sensor 130 is A, and the control target value is SP (i.e., the distance between the displacement sensor 130 and the target position C2). The calculation controller 142 performs modulus calculation on the above signals and outputs a control signal F1 for controlling the first fan 111 and a control signal F2 for controlling the second fan 112, and sends them to the corresponding fan frequency adjustment mechanisms 122 respectively. After being processed by the fan frequency adjustment mechanism 122, a frequency signal MV1 of the first fan 111 and a frequency signal MV2 of the second fan 112 are output to adjust the frequencies of the first fan 111 and the second fan 112, control the air pressure difference on both sides of the glass substrate 200, and use the thrust generated by the air pressure difference to push the glass substrate 200 towards the target position C2, thereby reducing and eliminating the swing of the glass substrate 200.

[0070] In this embodiment, the input position signal A is compared with the control target value SP. S is set as the detection range of the target area C3, that is, with the target position C2 as the central axis, the target area C3 is (SP - S, SP + S). If SP - S < A < SP + S, the glass substrate 200 is within the target range, and the calculation controller 142 outputs F1 = F2 = SP, and keeps the current values of MV1 and MV2 output by the fan frequency adjustment mechanism 122 unchanged.

[0071] If A > SP + S, that is, the glass substrate 200 deviates to the left, the calculation controller 142 outputs F1 = A, F2 = -A. The fan frequency adjustment mechanism 122 outputs MV1 to control the first fan 111 to increase the frequency, and can also control the second fan 112 to decrease the frequency at the same time, so that the thrust acting on the second surface 202 of the glass substrate 200 increases, and the glass substrate 200 is pushed towards the target position C2.

[0072] If A < SP - S, that is, the glass substrate 200 shifts to the right, the computer control system outputs F2 = A and F1 = -A. The fan frequency adjustment mechanism 122 outputs MV2 to control the second fan 112 to increase the frequency, and can also control the first fan 111 to decrease the frequency at the same time, so as to increase the thrust acting on the first surface 201 of the glass substrate 200 and push the glass substrate 200 towards the target position C2.

[0073] As Figure 1 、 Figure 3 and Fig.10 shown, in some embodiments, the glass substrate swing amount detection control system 100 further includes an audible and visual alarm 150. The audible and visual alarm 150 is communicatively connected to the control device 140. When the control device 140 is disconnected from the displacement sensor 130 or the distance between the glass substrate 200 and the target position C2 increases, the control device 140 can control the audible and visual alarm 150 to give an alarm.

[0074] In this embodiment, if the displacement sensor 130 or the conversion module 141 fails and the calculation controller 142 does not receive the position information, or after adjusting the frequency of the fan 110 and the distance between the fan 110 and the glass substrate 200, the swing amount of the glass substrate 200 is still too large, that is, the glass substrate 200 will swing outside the target area C3, then the calculation controller 142 outputs an alarm signal to trigger the audible and visual alarm 150 to remind the staff to troubleshoot in time and ensure the normal operation of the production line.

[0075] The present invention also proposes a glass substrate swing amount detection control method, which is used for the glass substrate swing amount detection control system 100 in any of the foregoing embodiments of the present invention.

[0076] For ease of understanding, the glass substrate swing amount detection control method of the embodiments of the present invention will be described below. As Fig.11 shown, the glass substrate swing amount detection control method in the embodiments of the present invention includes steps S110 to S140.

[0077] In step S110, the swing amount information of the glass substrate 200 and the target position C2 is obtained.

[0078] In step S120, based on the swing amount information, it is determined whether the glass substrate 200 is located outside the target area C3. When the glass substrate 200 can be located outside the target area C3, the first swing amount of one side surface of the glass substrate 200 and the target position C2, and the second swing amount of the other side surface and the target position C2 are calculated. Among them, the target position C2 is located at the center position of the target area C3.

[0079] In step S130, based on the first swing amount and the second swing amount, the swing direction of the glass substrate 200 is determined.

[0080] In step S140, based on the swing direction, the frequency of the air blower 110 located on one side of the swing direction of the glass substrate 200 is controlled to decrease and / or move away from the glass substrate 200, and / or the frequency of the air blower 110 located on the other side of the glass substrate 200 is increased and / or moved closer to the glass substrate 200, so that the glass substrate 200 moves towards the target position C2 and is reset within the target area C3.

[0081] In this embodiment, the swing amplitude of the glass substrate 200 is calculated based on the swing amount information of the glass substrate 200 and the target position C2, and it is determined whether the glass substrate 200 can swing outside the target area C3.

[0082] When the glass substrate 200 can swing outside the target area C3, the first swing amount and the second swing amount corresponding to the two side surfaces of the glass substrate 200 are calculated, and then the swing direction of the glass substrate 200 is determined.

[0083] When the glass substrate 200 is biased towards one of the side walls, according to the swing direction of the glass substrate 200, the acting force on the glass substrate 200 can be adjusted by at least one, two or more of the following methods: Controlling the frequency of the air blower 110 on this side (i.e., the side where the glass substrate 200 is biased towards the side wall) to decrease, controlling the air blower 110 on this side to move away from the glass substrate 200, controlling the frequency of the air blower 110 on the other side to increase, controlling the air blower 110 on the other side to move closer to the glass substrate 200, and by changing the pressure difference between the two sides of the glass substrate 200, so that the acting force towards the target position C2 on the surface of the glass substrate 200 closer to the side wall increases, thereby reducing and even eliminating the swing amplitude of the glass substrate 200, and avoiding scratching of the glass substrate 200 when passing through the narrow slit C1.

[0084] As Fig.12 shown, the input position signal A is compared with the control target value SP, and S is set as the detection range of the target area C3, that is, with the target position C2 as the central axis, the target area C3 is (SP - S, SP + S). If SP - S < A < SP + S, the glass substrate 200 is within the target range, and the controller 142 outputs F1 = F2 = SP, and the current values of the outputs MV1 and MV2 of the air blower frequency adjustment mechanism 122 are kept unchanged.

[0085] If A > SP + S, that is, the glass substrate 200 shifts to the left. The calculation controller 142 outputs F1 = A and F2 = -A. The fan frequency adjustment mechanism 122 outputs MV1 to control the first fan 111 to increase the frequency, and can also simultaneously control the second fan 112 to decrease the frequency, so as to increase the thrust acting on the second surface 202 of the glass substrate 200 and push the glass substrate 200 towards the target position C2.

[0086] If A < SP - S, that is, the glass substrate 200 shifts to the right. The computer control system outputs F2 = A and F1 = -A. The fan frequency adjustment mechanism 122 outputs MV2 to control the second fan 112 to increase the frequency, and can also simultaneously control the first fan 111 to decrease the frequency, so as to increase the thrust acting on the first surface 201 of the glass substrate 200 and push the glass substrate 200 towards the target position C2.

[0087] In some alternative embodiments, after adjusting the frequency of the fan 110 on one side of the glass substrate 200 to the maximum value and the frequency of the fan 110 on the other side to the minimum value, the swing amount information is obtained again. If the glass substrate 200 is still able to be located outside the target area C3, then based on the swing direction, control the fan 110 on the swing direction side of the glass substrate 200 to move away from the glass substrate 200 and / or control the fan 110 on the other side of the glass substrate 200 to move closer to the glass substrate 200, so that the glass substrate 200 moves towards the target position C2 and is restored within the target area C3.

[0088] In this embodiment, first, the pressure difference on both sides of the glass substrate 200 is adjusted by controlling the frequency of the fan 110, and a force towards the target position C2 is applied to the glass substrate 200. If after adjusting the frequency of the fan 110 on one side of the glass substrate 200 to the maximum value and the frequency of the fan 110 on the other side to the minimum value, the swing amount of the glass substrate 200 is still too large, that is, the glass substrate 200 is still able to be located outside the target area C3, and the adjustment function of the swing amount of the glass substrate 200 cannot be realized only by adjusting the frequency of the fan 110, then control the distance between the fans 110 on both sides of the glass substrate 200 and the glass substrate 200, so that the fan 110 on the swing direction side of the glass substrate 200 moves away from the glass substrate 200 and / or control the fan 110 on the other side of the glass substrate 200 to move closer to the glass substrate 200, so that the glass substrate 200 moves towards the target position C2 and is restored within the target area C3, so as to realize the progressive control of the swing amount of the glass substrate 200 and improve the control accuracy of the swing amplitude of the glass substrate 200.

[0089] The glass substrate swing amount detection and control method provided by the embodiment of the present invention includes: obtaining swing amount information of a glass substrate 200 and a target position C2; judging whether the glass substrate 200 is located outside a target area C3 based on the swing amount information, and when the glass substrate 200 can be located outside the target area C3, calculating a first swing amount between a surface of one side of the glass substrate 200 and the target position C2, and a second swing amount between a surface of the other side and the target position C2, wherein the target position C2 is located at the center of the target area C3; judging a swing direction of the glass substrate 200 based on the first swing amount and the second swing amount; and controlling a fan 110 located on one side of the swing direction of the glass substrate 200 to reduce its frequency and / or move away from the glass substrate 200, and / or to increase its frequency and / or move closer to the glass substrate 200, based on the swing direction, so that the glass substrate 200 moves toward the target position C2 and is relocated in the target area C3.

[0090] The glass substrate swing amount detection and control method provided by the embodiment of the present invention can: detect the swing amount of the glass substrate 200, determine whether the swing amplitude of the glass substrate 200 is too large, and accurately adjust the wind pressure on both sides of the glass substrate 200 by controlling the power of the fans 110 located on both sides of the glass substrate 200 and / or the distance between the fans 110 and the glass substrate 200, so that the swing amount of the glass substrate 200 is within a safe range, avoiding scratches on the glass substrate 200, and improving the yield rate of the glass substrate 200. At the same time, the fans 110 can cooperate with the indoor air conditioner to further accelerate the cooling speed of the glass substrate 200, thereby improving the cooling effect.

[0091] The present invention further proposes a method for detecting and controlling the swing amount of a glass substrate in a closed space. The method for detecting and controlling the swing amount of a glass substrate in a closed space is applied to a glass substrate swing amount detection and control system 100 of any of the aforementioned embodiments of the present invention. A glass substrate 200 is located in an at least partially closed closed space, and the closed space includes two partially connected chambers. The glass substrate 200 is at least partially located at the connecting point of the two chambers, and a fan is connected to the outside and can deliver airflow to the corresponding chamber.

[0092] like Fig.13 As shown, the method for detecting and controlling the swing amount of a glass substrate in a closed space in the embodiment of the present invention includes steps S210 to S240.

[0093] In step S210, the swing amount information of the glass substrate 200 and the target position C2 is obtained; In step S220, based on the swing amount information, it is determined whether the glass substrate 200 is located outside the target area C3. When the glass substrate 200 can be located outside the target area C3, a first swing amount between one side surface of the glass substrate 200 and the target position C2 and a second swing amount between the other side surface and the target position C2 are calculated. The target position C2 is located at the center of the target area C3.

[0094] In step S230 , the swing direction of the glass substrate 200 is determined based on the first swing amount and the second swing amount.

[0095] In step S240, based on the swing direction, the frequency of the fan 110 located on one side of the swing direction of the glass substrate 200 is controlled to increase and / or approach the glass substrate 200, and / or the frequency of the fan 110 located on one side of the swing direction of the glass substrate 200 is controlled to decrease and / or move away from the glass substrate 200, so that the air pressure of the chamber located on one side of the swing direction increases and / or the air pressure of the chamber located on the other side decreases, and the glass substrate 200 is pushed toward the target position C2 and restored to the target area C3.

[0096] In this embodiment, when the glass substrate 200 passes through the narrow gap C1, the space for the fan 110 to deliver the airflow can be a completely enclosed space or a semi-enclosed space. Therefore, when the fan 110 delivers the airflow to one of the chambers in the enclosed space, it can change the air pressure in the chamber, thereby changing the force acting on the surface of the glass substrate 200 to adjust the swing amount of the glass substrate 200.

[0097] When the glass substrate 200 is biased toward one side of the wall, the force acting on the glass substrate 200 can be adjusted by at least one, two or more of the following methods according to the swing direction of the glass substrate 200: The frequency of the fan 110 on this side (i.e., the side where the glass substrate 200 is inclined toward the wall) is increased, the fan 110 on this side is controlled to be close to the glass substrate 200, and the frequency of the fan 110 on the other side is controlled to be reduced, and the fan 110 on the other side is controlled to be away from the glass substrate 200. By changing the air pressure of the chambers on both sides of the glass substrate 200, the force acting on the surface of the glass substrate 200 closer to the wall toward the target position C2 is increased, so that the glass substrate 200 is pushed toward the target position C2, thereby reducing or even eliminating the swing amplitude of the glass substrate 200, thereby preventing the glass substrate 200 from being scratched when passing through the narrow gap C1.

[0098] When the space where the fan 110 delivers airflow is a semi-enclosed space, as the air pressure in the semi-enclosed space increases, the gas in the space will gradually leak to the outside. Therefore, by controlling the fan 110 to be close to or away from the glass substrate 200, the air pressure near the surfaces on both sides of the glass substrate 200 can change faster and more obviously, thereby strengthening the force exerted on the surface of the glass substrate 200 and ensuring the effect of adjusting the swing amplitude of the glass substrate 200.

[0099] The glass substrate swing amount detection and control method provided in the embodiment of the present invention can detect the swing amount of the glass substrate 200 in the closed space, determine whether the swing amplitude of the glass substrate 200 is too large, and adjust the air pressure of the chamber on both sides of the glass substrate 200 by controlling the power of the fan 110 located on both sides of the glass substrate 200 and / or the distance between the fan 110 and the glass substrate 200, thereby achieving precise adjustment of the swing amount of the glass substrate 200, so that the swing amount of the glass substrate 200 is within a safe range, avoiding scratches on the glass substrate 200, and improving the yield rate of the glass substrate 200. At the same time, the fan 110 can cooperate with the indoor air conditioner to further accelerate the cooling speed of the glass substrate 200, thereby improving the cooling effect.

[0100] For the above method embodiment, the embodiment of the present invention also provides Fig.14 A glass substrate swing amount detection and control device shown includes: a processor 301 and a memory 302, wherein the memory 302 stores instructions; the processor 301 calls the instructions in the memory 302, so that the processor 301 executes the glass substrate swing amount detection and control method of any of the aforementioned embodiments of the present invention or the glass substrate swing amount detection and control method in a closed space of any of the aforementioned embodiments of the present invention.

[0101] The glass substrate swing amount detection and control method provided by the embodiment of the present invention comprises: acquiring swing amount information between a glass substrate and a target position; judging whether the glass substrate is located outside a target area based on the swing amount information, and when the glass substrate can be located outside the target area, calculating a first swing amount between a surface of one side of the glass substrate and the target position, and a second swing amount between a surface of the other side of the glass substrate and the target position, wherein the target position is located at the center of the target area; judging a swing direction of the glass substrate based on the first swing amount and the second swing amount; and controlling a fan located on one side of the swing direction of the glass substrate to reduce its frequency and / or move away from the glass substrate, and / or controlling a fan located on the other side of the glass substrate to increase its frequency and / or move closer to the glass substrate, based on the swing direction, so that the glass substrate moves toward the target position and is relocated within the target area.

[0102] The glass substrate swing amount detection and control method provided in an embodiment of the present invention in a closed space includes: obtaining swing amount information between a glass substrate and a target position; judging whether the glass substrate is located outside a target area based on the swing amount information, and when the glass substrate can be located outside the target area, calculating a first swing amount between a surface of one side of the glass substrate and the target position, and a second swing amount between a surface of the other side of the glass substrate and the target position, wherein the target position is located at the center of the target area; judging a swing direction of the glass substrate based on the first swing amount and the second swing amount; and controlling a fan located on one side of the swing direction of the glass substrate to increase its frequency and / or approach the glass substrate, and / or to reduce its frequency and / or move away from the glass substrate, based on the swing direction, so that the air pressure of a chamber located on one side of the swing direction increases and / or the air pressure of a chamber located on the other side decreases, thereby pushing the glass substrate toward the target position and restoring it in the target area.

[0103] The glass substrate swing amount detection and control device provided by the embodiment of the present invention can detect the swing amount of the glass substrate and determine whether the swing amplitude of the glass substrate is too large by implementing the above method, and accurately adjust the wind pressure on both sides of the glass substrate or the air pressure of the chamber on both sides of the glass substrate by controlling the power of the fans located on both sides of the glass substrate and / or the distance between the fans and the glass substrate, so that the swing amount of the glass substrate is within a safe range, thereby avoiding scratches on the glass substrate and improving the yield rate of the glass substrate. At the same time, the fans can cooperate with the indoor air conditioner to further accelerate the cooling speed of the glass substrate, thereby improving the cooling effect.
