In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0039] The following will be described in detail according to the drawings Figure 1 to the drawings Figure 9The glass detection and falling piece device and the glass production line are respectively introduced with two embodiments.

[0040] As Figures 1 to 5 shown, in the first embodiment of the utility model, the glass detection and falling piece device includes transmission mechanism and detection mechanism. Among them, detection mechanism includes detection sensor, detection sensor is used to retrieve whether glass exists defect, and can send signal to transmission mechanism according to detection result.

[0041] As Figure 1 , Figure 2 shown, transmission mechanism includes falling piece assembly 12 and two transmission assemblies 11, and two transmission assemblies 11 are used to support the bottom surface of glass and convey glass along the preset first direction (such as X axis shown in the figure), and falling piece assembly 12 is drivingly connected to two transmission assemblies 11, and can move transmission assembly 11 along the preset second direction (such as Y axis shown in the figure, and the preset second direction is perpendicular to the preset first direction) according to the signal sent by detection mechanism, to switch transmission mechanism between the first state and the second state. The spacing (such as shown by d in the figure) between two transmission assemblies 11 along the preset second direction in the first state is greater than the width dimension of glass, so that glass can fall between two transmission assemblies 11, to discharge glass with defects. The spacing between two transmission assemblies 11 along the preset second direction in the second state is less than the width dimension of glass, so that glass can be supported by two transmission assemblies 11 and continue to be conveyed. Figure 2

[0042] Exemplarily, when detection mechanism detects that glass does not exist defect, detection sensor sends the signal that falling piece is not needed to falling piece assembly 12, at this time, falling piece assembly 12 reduces the spacing between two transmission assemblies 11 to less than the width dimension of glass (i.e. changes to the second state), to ensure that glass can be supported by two transmission assemblies 11 at the same time and cannot fall, and can continue to convey glass along the preset first direction through two transmission assemblies 11. When detection mechanism detects that glass exists defect, detection sensor sends the signal that falling piece is needed to falling piece assembly 12, at this time, falling piece assembly 12 increases the spacing between two transmission assemblies 11 to be greater than the width dimension of glass (i.e. changes to the first state), so that glass cannot be supported by two transmission assemblies 11 at the same time, to discharge glass with defects.

[0043] By adjusting the spacing between two transmission assemblies 11 through the falling piece assembly 12, glass can be discharged in the falling piece mode, and the phenomenon that discharge is not complete or unsuccessful can be avoided, to ensure that glass with defects will not continue to circulate in the glass production line, to avoid the phenomenon of blockage, impact and the like at subsequent process devices, to protect the process devices and make the production of glass can be carried out normally. ​

[0044] Optionally, such as Figure 1 , Figure 3 As shown, the transmission mechanism also includes a first support 21, and the drop assembly 12 includes a slide rail 121 and a linear drive 122. The slide rail 121 is arranged along a preset second direction and fixedly installed on the first support 21. The transmission assembly 11 is slidably connected to the slide rail 121, and the linear drive 122 is drively connected to the transmission assembly 11 and can drive the transmission assembly 11 to move along the slide rail 121, thereby changing the distance between the two transmission assemblies 11.

[0045] Specifically, in this embodiment, the first bracket 21 is provided with two slide rails 121, both of which extend along a preset second direction. Each end of each transmission component 11 is connected to one slide rail 121, and each transmission component 11 is connected to a linear drive component 122. When a corresponding signal is received, the two transmission components 11 move simultaneously, thereby changing the distance between the two transmission components 11.

[0046] Optionally, in some embodiments, only one of the transmission components 11 may be mounted on the first bracket 21 via the slide rail 121, and the transmission component 11 may be moved by the linear drive 122 to change the distance between the two transmission components 11, thus achieving the switching between the first and second states. Of course, compared to moving only one transmission component 11, moving both transmission components 11 simultaneously can better achieve the film dropping and avoid incomplete film dropping.

[0047] Preferably, in this embodiment, the transmission mechanism further includes a first mounting member 25 and a second mounting member 26, both of which are slidably connected to the slide rail 121 and connected to the linear drive member 122. The linear drive member 122 can adjust the distance between the first mounting member 25 and the second mounting member 26 along a preset second direction, and the transmission component 11 is mounted on the second mounting member 26. The transmission mechanism also includes a spacing adjustment component 13, which is connected to the first mounting member 25 and is used to adjust the position of the first mounting member 25 along the preset second direction. In this way, the position of the first mounting member 25 can be changed by the spacing adjustment component 13, thereby adjusting the range of motion of the spacing between the two transmission components 11, so that the glass detection and dropping device is suitable for glass of different widths.

[0048] Exemplarily, for the glass with smaller width size, the first mounting member 25 can be moved towards the other conveying assembly 11 by the interval adjusting assembly 13, so that the interval active range between the two conveying assemblies 11 is in a smaller numerical range. For the glass with larger width size, the first mounting member 25 can be moved away from the other conveying assembly 11 by the interval adjusting assembly 13, so that the interval active range between the two conveying assemblies 11 is in a larger numerical range.

[0049] Specifically, in the embodiment, the first support 21 is provided with a connecting seat 211, and a bearing is arranged in the connecting seat 211. The interval adjusting assembly 13 comprises a screw rod 131 and a hand wheel 132, the axis direction of the screw rod 131 is arranged along the preset second direction, and the screw rod 131 is rotatably arranged in the connecting seat 211 through the bearing. The first mounting member 25 is engagedly connected to one side of the screw rod 131 located in the connecting seat 211, and the end of the screw rod 131 located on the other side of the connecting seat 211 is connected with the hand wheel 132. When it is needed to adjust the interval active range between the two conveying assemblies 11, the position of the first mounting member 25 can be changed along the preset second direction by rotating the hand wheel 132, so that the active range of the conveying assembly 11 is changed, and then the falling and conveying requirements of the glass with different width sizes are adapted. Alternatively, in some embodiments, the screw rod 131 can also be replaced by a bolt or the like.

[0050] Preferably, in the embodiment, one first mounting member 25 and one second mounting member 26 are connected to each conveying assembly 11 respectively, and one interval adjusting assembly 13 is connected to each first mounting member 25, so that the two conveying assemblies 11 can be adjusted along the preset second direction with a larger amplitude. Of course, in some embodiments, only one interval adjusting assembly 13 can be arranged, and only one conveying assembly 11 is connected to the interval adjusting assembly 13, which can also realize the adjustment of the interval active range between the two conveying assemblies 11, and also belongs to the range to be protected by the utility model.

[0051] Further, in the embodiment, the conveying assembly 11 comprises a conveying belt 111 and a conveying belt motor 112, and the conveying belt 111 can convey the glass along the preset first direction and transport the glass along the preset second direction under the driving of the conveying belt motor 112. When the conveying mechanism is in the second state, the bottom of the glass is supported by the conveying belts 111 in the two conveying assemblies 11, so that the glass is stably transported. When the conveying mechanism is in the first state, the interval between the two conveying assemblies 11 is enlarged under the action of the falling assembly 12, so that the bottom of the glass is only supported by the conveying belt 111 in one conveying assembly 11 or is not supported by the conveying belt 111, so that the glass falls through the space between the two conveying assemblies 11 without support, and the defective glass is discharged.

[0052] In the embodiment, the detection mechanism further comprises a second support 22, and the detection sensor is a CCD camera, which is arranged as a linear array on the second support 22 and scans the glass from top to bottom. The detection mechanism further comprises a computing element, which is connected to the detection sensor and performs sample-based convolution operation on the image by using a machine learning algorithm after obtaining the image of the whole glass, segments the defects and counts the defect probability and area, and outputs a corresponding signal (for example, an NG signal) according to a set evaluation criterion. Optionally, along the thickness direction, one side of the glass is provided with a hexagonal embossed texture, and the other side is a smooth surface. The computing element can also output a signal indicating the forward placement (for example, the smooth surface downward) or the reverse placement (for example, the smooth surface upward) of the glass according to whether the image of the glass contains the feature of the hexagonal embossed texture, which facilitates the subsequent processing of the process equipment.

[0053] Further, as shown in Figure 4 、 Figure 5 , the glass detection and falling device further comprises a third support 23 and an illumination mechanism, the illumination mechanism comprises a light source, the third support 23 and the second support 22 are fixedly connected, and the light source can be fixed above the transmission assembly 11. The light source can irradiate the glass at a predetermined angle, thereby reducing the influence of ambient light on the defect detection process and improving the recognition accuracy of the features such as defects. Preferably, the glass detection and falling device further comprises a fourth support 24 and a background mechanism, the background mechanism comprises a background plate (not shown in the figure), the fourth support 24 and the second support 22 are fixedly connected, and the background plate can be fixed below the transmission assembly 11, thereby avoiding the complex texture of the ground or other structures being photographed together when photographing, which leads to a decrease in the recognition accuracy of the features such as defects.

[0054] It should be noted that in some embodiments, the glass detection and falling device further comprises a collection container (not shown in the figure), which is arranged below the transmission mechanism. The collection container is used to collect the fallen glass to avoid the impact of the discharged glass on the production environment.

[0055] As shown in Figures 6 to 9 , in the second embodiment provided by the utility model, the glass detection and falling device also comprises a transmission mechanism, a detection mechanism, an illumination mechanism and a background mechanism, and the transmission mechanism also comprises a spacing adjustment assembly 13 capable of adjusting the spacing d. The difference between the first embodiment and the second embodiment is that the specific structures of the spacing adjustment assembly 13 and the transmission assembly 11 are different.

[0056] Exemplarily, in the embodiment, the pitch adjusting assembly 13 comprises a lead screw 131 and a lead screw motor 133, the first support 21 is provided with a connecting seat 211, and a bearing is arranged in the connecting seat 211. The axis direction of the lead screw 131 is arranged along the preset second direction, and the lead screw 131 is rotationally connected to the first support 21 through the bearing. The first mounting member 25 is meshingly connected with the lead screw 131, and the lead screw motor 133 can drive the lead screw 131 to rotate, so that the lead screw 131 can rotate, and the first mounting member 25 can be moved along the preset second direction, thereby realizing the change of the active range of the pitch between the two conveying assemblies 11.

[0057] With continuous reference to Figures 6 to 9 As shown in the second embodiment provided in the utility model, each conveying assembly 11 comprises a conveying driving member, a chain wheel 116 and a plurality of rollers 113, the conveying driving member is drivingly connected with the chain wheel 116 and the plurality of rollers 113, and the rollers 113 of each conveying assembly 11 can support one side of the glass, and the two conveying assemblies 11 can jointly support the glass and rotate the rollers 113 to convey the glass under the driving of the conveying driving member.

[0058] Preferably, the conveying driving member comprises a first conveying driving member 114 and a second conveying driving member 115, at least one roller 113 located at one end of the conveying assembly 11 is drivingly connected with the first conveying driving member 114 along the preset first direction, and at least one roller 113 located at the other end of the conveying assembly 11 is drivingly connected with the second conveying driving member 115, and the first conveying driving member 114 and the second conveying driving member 115 can respectively drive the rollers 113 to rotate at different speeds. In this way, two sections of the glass detecting and falling device can be realized (as shown in the dotted box in Figure 7 and the rollers 113 in the right dotted box rotate at a higher speed, so that the pitch of the glass increases during the transportation from left to right. Figure 7 and the rollers 113 in the right dotted box rotate at a higher speed, so that the pitch of the glass increases during the transportation from left to right.
