[0045] First embodiment:

[0046] Reference Figure 1 The embodiment of the present application provides a curved glass detection device, comprising: a frame 1, a conveying mechanism 2, a plurality of lifting mechanisms 3, a control system 4, a shooting mechanism 5, an end face detection mechanism 6 and an analysis system, wherein the frame 1 is n-shaped; the analysis system is arranged beside the frame 1;

[0047] The conveying mechanism is arranged on the inner side of the conveying frame 1, and the conveying mechanism 2 is preferably a belt conveyor line, and the curved glass is placed and conveyed by the belt;

[0048] The number of the lifting mechanisms 3 is an even number, which can be two, four or six. In the present embodiment, the number of the lifting mechanisms 3 is preferably two; the two lifting mechanisms 3 are symmetrically arranged on the inner top surface of the frame 1, for lifting the curved glass;

[0049] Reference Figure 1 and Figure 2 The lifting mechanism 3 includes two groups of sliding components 31, an electric push rod 32, a support 33, and multiple push rods 34. The two groups of sliding components 31 are symmetrically arranged on the inner top surface of the frame 1, respectively. The electric push rod 32 is vertically installed on the sliding end of the sliding component 31, and the support 33 is fixed to the bottom of the electric push rod 32. The multiple push rods 34 are divided into two groups and are symmetrically installed on the support 33. In this embodiment, the number of the push rods 34 is set to an even number, preferably two, and the top of the push rod 34 is set to a semicircular or hemispherical shape. The outer arc surface of the push rod 34 abuts against the inner arc surface of the curved glass. The sliding component 31 and the electric push rod 32 are both electrically connected to the control system 4.

[0050] The working process of the above-mentioned lifting mechanism 3 is as follows: when the conveying mechanism 2 conveys the curved glass to be inspected between the two sliding components 31, the sliding ends of the two sliding components 31 are started at the same time, and the sliding ends of the sliding components 31 drive the electric push rods 32 to slide to the left and right ends of the curved glass, and the two electric push rods 32 are started at the same time, and the electric push rods 32 extend downward, and the support 33 and the multiple push rods 34 on the support 33 extend into the inner side of the curved glass, and the sliding end of the sliding component 31 stops moving, and the multiple push rods 34 abut against the inner curved surface of the curved glass. Since the supports 33 and the multiple push rods 34 at the left and right ends of the curved glass are symmetrically arranged in the left and right directions, when the curved glass is lifted up by the multiple push rods 34, the position of the curved glass can be straightened to facilitate the shooting mechanism 5 to shoot the curved glass.

[0051] The lifting mechanism 3 also includes a plurality of elastic support components 35, a top block 36, a laser rangefinder 37 and a baffle 38. The number of the elastic support components 35 is set to two, and the top of the top block 36 is set to be semicircular or hemispherical.

[0052] The elastic support assembly 35, the top block 36, the laser rangefinder 37 and the baffle 38 are arranged on the lifting mechanism 3, which can help the present invention to detect the curvature of the curved glass with the help of the lifting mechanism 3, and send the detection result to the analysis system. If the detected curvature is within the qualified curvature range, it is judged as a qualified product. If it is not within this range, the curved glass is judged as an unqualified product.

[0053] The lifting mechanism 3 also includes a plurality of anti-skid buffer sleeves, which are respectively wrapped on the outer surfaces of the top rod 34 and the top block 36. By arranging the anti-skid buffer sleeves on the surfaces of the top rod 34 and the top block 36, an anti-skid effect can be achieved, and at the same time, the top rod 34 and the top block 36 can be prevented from damaging the curved glass, causing glass breakage or scratches.

[0054] The lifting mechanism 3 further includes a reinforcing rib 39 , which is fixedly mounted on the inner side surface of the support 33 to prevent the support 33 from being deformed and damaged.

[0055] Reference Figure 1 The shooting mechanism 5 is installed at the middle position of the inner top surface of the frame 1 and is used to shoot the curved glass. The shooting mechanism 5 includes a rotating assembly 51 and a camera assembly 52. ​​The camera assembly 52 is installed at the middle position of the inner top surface of the frame 1 through the rotating assembly 51. The camera assembly 52 includes a plurality of cameras and a mounting plate. The mounting plate is arranged on the movable end of the rotating assembly 51. A plurality of cameras are arranged on the bottom surface of the mounting plate along a horizontal line distributed in the left and right directions. The rotating assembly 51 is used to drive the camera assembly 52 to rotate. The rotating assembly 51 and the camera assembly 52 are both electrically connected to the control system 4, and the camera assembly 52 is electrically connected to the analysis system.

[0056] Reference Figure 1 , Figure 3 and Figure 4 The end face detection mechanism 6 is installed on the conveying mechanism 2, and the end face detection mechanism 6 is used to detect the end face damage of the curved glass, and the end face detection mechanism 6 is electrically connected to the analysis system;

[0057] Reference Figure 1 and Figure 4The end face detection mechanism 6 includes two first slide rails 61, four electric sliders 62, four driving members 63, four rotating shafts 64, four connecting rods 65, two detection airbags 66 and two air pressure sensors 67; the two first slide rails 61 are symmetrically installed on the left and right sides of the top of the conveying mechanism 2, the four electric sliders 62 are grouped in pairs and symmetrically installed on the two first slide rails 61, the four rotating shafts 64, the four connecting rods 65 and the four driving members 63 are respectively installed on the four electric sliders 62, and the rotating shafts 64 are rotatably connected to the electric sliders 62. The rotating shaft 64 is arranged horizontally, and the driving end of the driving member 63 is connected to the corresponding rotating shaft 64 for driving the corresponding rotating shaft 64 to rotate. The end of the rotating shaft 64 away from the driving member 63 is connected to the connecting rod 65, and both ends of each detection airbag 66 are respectively connected to the corresponding two connecting rods 65. Two air pressure sensors 67 are respectively connected to the front and rear sides of the two detection airbags 66 for detecting the internal air pressure of the detection airbags 66; the air pressure sensor 67 is electrically connected to the analysis system; the electric slider 62 and the driving member 63 are both electrically connected to the control system 4.

[0058] The end face detection mechanism 6 further includes four mounting seats 68 , which are respectively mounted on the four electric sliders 62 , and the rotating shaft 64 is rotatably connected to the electric slider 62 via the mounting seats 68 .

[0059] The two electric sliders 62, two driving members 63, two rotating shafts 64, two connecting rods 65, a detection airbag 66 and an air pressure sensor 67 located on the front side constitute a front end face detection component; the two electric sliders 62, two driving members 63, two rotating shafts 64, two connecting rods 65, a detection airbag 66 and an air pressure sensor 67 located on the rear side constitute a rear end face detection component.

[0060] A control system 4 is installed on the frame 1 , and the conveying mechanism 2 , the lifting mechanism 3 , the photographing mechanism 5 and the end face detection mechanism 6 are all electrically connected to the control system 4 .

[0061] The working process of the present invention is as follows: first, the curved glass to be inspected is placed on the conveying mechanism 2 at equal distances, and the conveying mechanism 2 drives the curved glass to slide in the direction of the frame 1, and the camera assembly 52 takes a photo of the curved glass to be inspected. When taking photos, the rotating assembly 51 drives the camera assembly 52 to rotate according to the model of the curved glass, so that the multiple cameras on the camera assembly 52 always take real-time photos of the glass along the vertical line of the curved glass. In this way, the defects inside the curved glass can be avoided from being magnified as much as possible. The multiple cameras send the photos of the curved glass to the analysis system in real time to analyze the internal defects of the glass, such as bubbles and internal inclusions inside the curved glass.

[0062] When the arched part of the middle part of the curved glass slides to the inner side of the frame 1, the lifting mechanism 3 is started, the lifting mechanism 3 lifts the curved glass upward, aligns the position of the curved glass, detects the curvature of the curved glass, and sends the curvature detection data to the analysis system for analysis. The analysis system determines the curvature of the curved glass. After completion, the analysis system sends the curvature value of the curved glass to the end face detection mechanism 6, and the rear end face detection component slides toward the rear end face of the curved glass. At the same time, the driving member 63 drives the corresponding rotating shaft 64 and connecting rod 65 to rotate respectively until the connection surfaces of the two connecting rods 65 on the front side and the two connecting rods 65 on the rear side are connected. The connecting surfaces are parallel to the front and rear end surfaces of the curved glass respectively; the electric slider 62 is started, and the corresponding electric slider 62 drives the detection airbag 66 to slide toward the end surface of the curved glass until the detection airbag 66 completely wraps the corresponding front and rear end surfaces of the curved glass; the air pressure sensor 67 detects the internal air pressure values ​​of the two detection airbags 66 respectively, and sends the detection data to the analysis system; the analysis system receives the data, and if the internal air pressure value of the detection airbag 66 is not within the qualified air pressure value range, it is marked as a defective product; if the internal air pressure value of the detection airbag 66 is within the qualified air pressure value range, it is marked as a qualified product; and the marking information is sent to the control system 4;

[0063] When the lifting mechanism 3 is lifted, the two detection airbags 66 wrap the two ends of the curved glass, which can also prevent the curved glass from sliding down, and play a role in further fixing the curved glass.

[0064] Second embodiment:

[0065] The curved glass detection device further comprises a fill-in light mechanism 7, which is mounted on the lifting mechanism 3, and comprises an upper light source 71 and a lower light source 72, wherein the upper light source 71 is mounted on the fixed end of the electric push rod 32, and the lower light source 72 is mounted on the support 33, and both the upper light source 71 and the lower light source 72 are electrically connected to the control system 4. The fill-in light mechanism 7 is used to illuminate the curved glass, and the light source generated by the fill-in light mechanism 7 can be a variety of different colors such as green or yellow. By setting the fill-in light mechanism 7, the shooting mechanism 5 can better take pictures of the internal defects of the curved glass, and the pictures are clearer. Generally, glass is often detected by end face analysis. During the process of taking pictures, the size of the end face will also be magnified, and the pictures are easy to be unclear, which affects the end face detection result. The end face detection mechanism 6 of the present invention has a simple structure and is easy to use. The end face of the curved glass is detected by two detection airbags 66, and the end face detection does not require taking pictures. The defects of the end face are converted into air pressure values, and the air pressure values ​​are used for analysis and judgment, so the detection accuracy is higher.

[0066] Another aspect of the present invention further provides a method for detecting the end face of curved glass. The present invention uses an end face detection mechanism 6 to detect the end face of the curved glass, which specifically includes the following steps:

[0067] Step S10, firstly, the curved glass on the conveying mechanism 2 is lifted upward by a plurality of the lifting mechanisms 3;

[0068] Step S20, the front and rear detection airbags 66 are driven by the corresponding electric sliders 62 to slide toward the front and rear end surfaces of the curved glass respectively;

[0069] Step S30, driving the corresponding rotating shaft 64 to rotate by the driving member 63 until the connection surfaces of the two connecting rods 65 on the front side of the curved glass and the connection surfaces of the two connecting rods 65 on the rear side of the curved glass are parallel to the front and rear end surfaces of the curved glass respectively;

[0070] Step S40, starting the electric slider 62, and the corresponding electric slider 62 drives the detection airbag 66 to slide toward the end surface of the curved glass until the detection airbag 66 completely wraps the front and rear end surfaces of the corresponding curved glass;

[0071] Step S50, the air pressure sensor 67 detects the internal air pressure values ​​of the two detection airbags 66 respectively, and sends the detection data to the analysis system;

[0072] Step S60, the analysis system receives data, and if the internal air pressure value of the detection airbag 66 is not within the qualified air pressure value range, it is marked as a defective product; if the internal air pressure value of the detection airbag 66 is within the qualified air pressure value range, it is marked as a qualified product; and the marking information is sent to the control system 4.

[0073] The detection principle of this method is: since the front face detection component and the rear face detection component on the end face detection mechanism 6 are at the same distance from the front and rear end faces of the curved glass, when the two detection airbags 66 are completely wrapped on the front and rear end faces of the curved glass, if the end face is damaged or there are protrusions on the end face, there is a pressure difference between the internal air pressure of the detection airbag 66 and the air pressure of the end face of the flat glass. By setting up an air pressure sensor 67, the internal air pressure of the detection airbag 66 can be detected in real time. If the detected air pressure is within the qualified air pressure value range, it is a qualified product. Otherwise, it is an unqualified product.

[0074] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered within the protection scope of the present invention. In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
