[0029] Figure 1 An embodiment of the substrate glass detection device of the present application is schematically shown.

[0030] As shown in Figure 1 The present application discloses a substrate glass detection device, which comprises: a transportation assembly 10 comprising a lifting mechanism for vertically carrying a substrate glass 40; a detection assembly 20 disposed close to the transportation assembly 10 and provided with a detection mechanism; and a stabilizing assembly 30 disposed below the transportation assembly 10 and comprising a follow-up platform 31 and a stabilizing clamping arm 32, the follow-up platform 31 being capable of driving the stabilizing clamping arm 32 to move synchronously with the lifting mechanism.

[0031] Through the above structural design, the embodiment of the present application realizes auxiliary fixation of the substrate glass 40 by disposing the stabilizing assembly 30 below the transportation assembly 10, clamping the substrate glass 40 with the stabilizing clamping arm 32, and driving the substrate glass 40 to move together with the lifting mechanism above the follow-up platform 31, thereby stabilizing the position of the substrate glass, overcoming the problems of easy shaking and bending of the substrate glass, improving the detection speed and accuracy of the substrate glass 40, avoiding data errors, improving production efficiency, reducing the quality risk of products, and helping to improve product yield.

[0032] In some embodiments of the present application, as Figure 1As shown, the conveying mechanism comprises a conveying platform 11, a driving vehicle body 12 and a conveying gripper 13. The driving vehicle body 12 is movably installed on the conveying platform 11, and the conveying gripper 13 is arranged on the driving vehicle body 12 and suspended outside the conveying platform 11 to facilitate the grabbing and conveying of the substrate glass 40. In the embodiment of the present application, a sliding rail is arranged on the conveying platform 11, and a sliding block is arranged below the driving vehicle body 12, and the sliding rail and the sliding block are connected in cooperation to realize the sliding movement of the driving vehicle body 12. The sliding rail and the sliding block can be a commercially available linear guide rail, which is commonly used in high-precision linear reciprocating motion occasions, has high precision and small vibration, and can improve the conveying stability of the glass.

[0033] In some embodiments of the present application, as shown in Figure 1 The conveying gripper 13 of the conveying assembly 10 is arranged in multiple groups, and the multiple groups of conveying grippers 13 are arranged along the horizontal linear direction on one side of the driving vehicle body 12, which can realize stable and reliable grabbing of the substrate glass 40. In some preferred embodiments of the present application, in order to improve the efficiency, the conveying vehicle body can also be provided with conveying grippers 13 and detection assemblies 20 on both sides respectively to realize bilateral synchronous detection and improve the production efficiency.

[0034] In some embodiments of the present application, as shown in Figure 1 A double-shaft moving mechanism 34 is arranged on the follow-up platform 31, and the stable clamping arm 32 is movably installed on the follow-up platform 31 through the double-shaft moving mechanism 34. When the substrate glass 40 is conveyed to the detection room, the stable clamping arm 32 can be driven by the double-shaft moving mechanism 34 to move from a position that does not affect the conveying process of the substrate glass 40 to the position of the substrate glass 40 to contact the substrate glass 40, and after clamping and fixing the substrate glass 40, the stable clamping arm 32 moves with the substrate glass 40 to stabilize the position of the substrate glass 40 and reduce the occurrence of shaking and bending of the substrate glass 40. In some embodiments of the present application, the double-shaft moving mechanism 34 is a double-shaft linear sliding table, which comprises a first linear sliding rail arranged along a first direction and a second linear sliding rail arranged perpendicular to the first direction. The first linear sliding rail is a double sliding rail, and the second linear sliding rail is transversely arranged on the double sliding rail and can slide along the first direction. The stable clamping arm 32 is installed on the second linear sliding rail and can slide along the second direction.

[0035] In some embodiments of the present application, as shown in Figure 1 The stable clamping arm 32 comprises two groups of symmetrically arranged stable clamping arms 32, and the two groups of stable clamping arms 32 are oppositely arranged and correspond to the two groups of side edges of the substrate glass 40 respectively. Therefore, the stable clamping arm 32 of the embodiment of the present application can move to the two groups of side edges of the substrate glass 40 respectively to fix the substrate glass 40 from both sides and produce appropriate tensioning effect to keep the substrate glass 40 flat and stabilize the position of the substrate glass 40, thereby improving the detection precision and detection speed of the detection assembly 20, reducing data errors and accelerating the production efficiency.

[0036] In some embodiments of the present application, as shown in Figure 1 The stabilizing clamping arm 32 is in an inverted L-shaped structure, which is perpendicular to the moving plane of the substrate glass 40, and the end side of the inverted L-shaped structure is provided with a stabilizing clamping jaw 33. In the embodiments of the present application, one stabilizing clamping jaw 33 is provided. By arranging the stabilizing clamping arm 32 in an inverted L-shaped structure, the distance between the root of the stabilizing clamping arm 32 and the substrate glass 40 can be increased, thereby providing space for the design of the biaxial moving mechanism 34, so as to avoid interference with the transportation path of the substrate glass 40 after installation.

[0037] In addition, Figure 2 The structural design of the stabilizing assembly 30 of another embodiment of the substrate glass detection device of the present application is shown.

[0038] As shown in Figure 2 In some embodiments of the present application, a plurality of groups of stabilizing clamping jaws 33 are arranged vertically on the stabilizing clamping arm 32. The plurality of groups of stabilizing clamping jaws 33 can be positioned by multiple points, thereby improving the clamping stability and reliability, and at the same time, avoiding the phenomenon of glass damage caused by too small clamping area. In addition, in some embodiments of the present application, rubber pads are arranged on the inner sides of the stabilizing clamping jaws 33 and the lifting clamping jaws 13, which can provide cushioning for the clamping action and avoid damaging the substrate glass 40 during clamping.

[0039] In some embodiments of the present application, as shown in Figure 2 The vertical section of the stabilizing clamping arm 32 is in a telescopic structure, which includes an upper sleeve 35, a lower sleeve 36, and a driving cylinder (not shown). The upper sleeve 35 is connected to the lower sleeve 36 in a sleeved manner, and the output end of the driving cylinder is connected to the upper sleeve 35, so that the upper sleeve 35 can be driven to ascend and descend, thereby adjusting the position of the stabilizing clamping jaw 33 to match substrate glasses 40 of different sizes and improve the adaptability of the detection device of the present application.

[0040] In some embodiments of the present application, as shown in Figure 1 The detection assembly 20 includes a detection column 21, and the detection mechanism is a detection camera 22. A plurality of detection cameras 22 are arranged on the detection column 21 in a vertical direction, which can perform visual detection on the substrate glass 40 at each height, identify whether the substrate glass 40 has defects such as stripes, bubbles, and stones, and accurately locate the defect position, thereby providing reliable data for evaluating the substrate glass 40. It can be understood that the detection camera 22 can be connected to an upper computer to perform intelligent detection by using existing defect image sets, and this visual recognition means is well known to those skilled in the art and is not the improvement point of the present application, and will not be described here.

[0041] In some embodiments of the present application, as shown in Figure 2As shown, the follow-up platform 31 is also provided with a follow-up sensor 37, which is arranged in linkage with the double-shaft moving mechanism 34, so as to timely trigger the double-shaft moving mechanism 34 to make the stable clamping arm 32 quickly move to the position of the substrate glass 40 after detecting that the conveying assembly 10 conveys the substrate glass to the detection room, so as to accelerate the detection efficiency. The linkage connection mode is well known to those skilled in the art, for example, the follow-up sensor 37 and the double-shaft moving mechanism 34 are simultaneously connected to the same upper computer, and when the upper computer receives the detection reflection signal of the follow-up sensor 37, the linkage is triggered to control the movement of the double-shaft moving mechanism. The linkage mechanism is common in the art, and will not be described in detail here.

[0042] In combination Figures 1 to 2 As shown, the working principle of the embodiment of the application is illustrated:

[0043] The driving vehicle 12 on the conveying assembly 10 vertically conveys the substrate glass 40, and when it enters the semi-finished product inspection room, the driving vehicle 12 is temporarily stopped directly above the follow-up platform 31. The double-shaft moving mechanism 34 first drives the stable clamping arm 32 to move forward, so that the stable clamping jaw 33 is in the same vertical plane as the substrate glass 40. Then the double-shaft moving mechanism 34 moves left and right to drive the stable clamping arms 32 on both sides to contract inward. When the stable clamping jaw 33 clamps the substrate glass 40, the double-shaft moving mechanism 34 drives the stable clamping arms 32 on both sides to expand outward, so as to tightly fix the substrate glass 40 and flatten it for easy detection. Then the driving vehicle 12 and the follow-up platform 31 move at a constant speed in the direction of the arrow, so that the substrate glass 40 is stably passed through the detection camera 22 for photographing detection, and accurate quality determination is realized. After the substrate glass 40 completely passes through the detection camera 22, the stable clamping jaw 33 is opened, and the double-shaft moving mechanism 34 drives the stable clamping arm 32 to move outward and backward to return to the original position. Then the follow-up platform 31 also returns to the original position and waits for the next detection.

[0044] Therefore, the embodiment of the application has the following beneficial effects:

[0045] The accuracy of detection and the elimination of error data can be improved: the position of the substrate glass 40 in the detection is stabilized, the shaking of the glass is reduced or eliminated, and the speed and accuracy of the detection camera 22 in detecting the surface defects of the substrate glass 40 are improved; the production efficiency is improved: the time for abnormal data processing and re-detection caused by the shaking of the substrate glass 40 is reduced, which helps to improve the operation efficiency and production capacity of the production line; the quality risk is reduced: the product defect omission caused by shaking is reduced by stabilizing the substrate glass 40, and the quality risk is reduced.

[0046] In summary, the substrate glass detection device of the embodiment of the application comprises a conveying assembly, a detection assembly and a stabilizing assembly, the conveying assembly comprises a lifting mechanism for vertically carrying the substrate glass; the detection assembly is arranged close to the conveying assembly and is provided with a detection mechanism; the stabilizing assembly is arranged below the conveying assembly and comprises a follow-up platform and a stabilizing clamping arm, the follow-up platform can drive the stabilizing clamping arm to move synchronously relative to the lifting mechanism. The stabilizing assembly is arranged below the conveying assembly, the stabilizing clamping arm clamps the substrate glass, and the substrate glass moves together with the lifting mechanism above the follow-up platform under the driving of the follow-up platform, so that the auxiliary fixing of the substrate glass is realized, the detection speed and accuracy of the substrate glass are improved, the data error is avoided, the production efficiency is improved, the quality risk of the product is reduced, and the product yield is improved.
