Description

Technical Field

[0001] The utility model belongs to the technical field of glass substrate detection, and in particular relates to a glass substrate edge detection and positioning device and a glass substrate edge detection system. Background Art

[0002] During the production and processing of glass substrates, the appearance and quality of the glass substrates need to be inspected accordingly. For the edge inspection of glass substrates, a camera equipped with a light source is generally used as the inspection mechanism. After the transfer device transports the glass substrate to the corresponding position, the inspection mechanism moves along the edge of the glass substrate for inspection. In order to avoid the inability to effectively detect defects such as burrs on the glass edge due to excessive distance, the distance between the inspection mechanism and the edge of the glass substrate when moving generally needs to be controlled to be small and the position relatively accurate, and the cumulative deviation of the transfer device under long-term operation needs to be avoided. For production lines where the glass substrate is transported horizontally and the moving path of the inspection mechanism is perpendicular to the conveying path of the glass substrate, a sensor is generally set on the side of the moving path of the inspection mechanism at the inspection station. By detecting whether the edge of the glass substrate to be tested reaches the specified position, the sensor is fed back to the controller to control the transfer device to move the glass substrate or adjust the position of the glass substrate. When the edge of the glass substrate to be tested is complete, the inspection and positioning requirements can be met. However, glass substrates are brittle and thin, and during the cutting and edging processes, cracked edges or chipped corners may occur. During the movement of the glass substrate, the sensor may misjudge the cracked or chipped edge due to the presence of the cracked or chipped portion, so that the cracked or chipped edge is located at the sensor sensing position, but the glass substrate as a whole is offset from the moving path of the detection mechanism. When the detection mechanism moves, it is easy to collide with the glass substrate, causing the detection mechanism to be scratched or damaged, and the glass substrate may be shattered, making it difficult to clean and taking a long time to clean.

[0019] As Figures 1-3 shown, the present utility model provides a glass substrate edge positioning device, which includes the first induction mechanism 1 and the second induction mechanism 2 arranged at the edge detection station. Figure 3The horizontal arrow in the middle indicates the conveying direction of the glass substrate 100. The upstream and downstream of the conveying direction are the two ends of the conveying direction. The first sensing mechanism 1 is located at one end of the glass substrate 100 in the conveying direction in the edge detection station, and is used to detect whether the corresponding side edge of the glass substrate 100 reaches the position. The second sensing mechanism 2 is located at the other end of the glass substrate 100 in the conveying direction in the edge detection station. The second sensing mechanism 2 includes a sensing component 21. The sensing component 21 includes two sensing units 211. The sensing ends of the two sensing units 211 have a gap 212 in the conveying direction of the glass substrate 100, and this gap 212 is less than or equal to the safety distance between the detection mechanism 200 and the glass substrate 100 during the movement in edge detection. Among them, the first sensing mechanism 1 and all the sensing units 211 are arranged towards the direction where the glass substrate 100 is located in the edge detection station. The first sensing mechanism 1 and all the sensing units 211 are electrically connected to the controller of the glass substrate edge detection system. The first sensing mechanism 1 is specifically a distance sensor, model IG-028. The sensing unit 211 is specifically a photoelectric sensor, which lights up when an induction signal is obtained and goes out when no induction signal is obtained. The detection mechanism 200 is a camera with a light source.

[0020] When this glass substrate edge positioning device is applied to the glass substrate edge detection system, as the glass substrate 100 continuously moves along the conveying direction, when the first sensing mechanism 1 detects a signal, the transfer device for conveying the glass substrate 100 in the edge detection system stops. If one of the sensing units 211 of the sensing component 21 obtains an induction signal and the other sensing unit 211 has no signal, at this time, the corresponding side of the glass substrate 100 to the first sensing mechanism 1 reaches the position accurately, and the corresponding side of the glass substrate 100 to the second sensing mechanism 2 also reaches the position accurately. The side edge is located between the sensing ends of the two sensing units 211 of the sensing component 21. When the detection mechanism 200 moves along the Figure 3 up and down arrow directions, it will not collide with the glass substrate 100.

[0021] When the first sensing mechanism 1 detects a signal and both sensing units 211 of the sensing component 21 do not obtain an induction signal, at this time, both sensing units 211 are in the off state, which is regarded as an abnormal state:

[0022] ① If the corresponding side of the glass substrate 100 to the second sensing mechanism 2 has been subjected to edge detection in the previous process (this side is intact without breakage or missing corners), at this time, the abnormal state is that the corresponding side of the glass substrate 100 to the first sensing mechanism 1 has defects such as breakage or missing corners. The edge position detected by the first sensing mechanism 1 is specifically the edge of the breakage or missing corner position. The overall glass substrate 100 is in Figure 3shifted to the left from the perspective, and this shift exceeds the safe distance between the detection mechanism 200 and the glass substrate 100 during the moving detection, and at this time, when the detection mechanism 200 moves along Figure 3 the up and down arrow directions, it will collide with the glass substrate 100.

[0023] ② If the side of the glass substrate 100 corresponding to the second induction mechanism 2 has not been subjected to edge detection in the previous process (the situation on this side is unknown), there are two situations of abnormal states at this time. One is the same as the aforementioned ①, and the entire glass substrate 100 is Figure 3 shifted to the left from the perspective, and this shift exceeds the safe distance between the detection mechanism 200 and the glass substrate 100 during the moving detection. The other is that the entire glass substrate 100 is Figure 3 not shifted beyond the safe distance between the detection mechanism 200 and the glass substrate 100 during the moving detection from the perspective, but the position of the glass substrate 100 corresponding to the second induction mechanism 2 is damaged or has a missing corner.

[0024] In specific applications, it is possible to judge whether there is an abnormal state by the staff observing the number of times the induction unit 211 lights up and goes out with the naked eye, or a warning module is set on the controller in the glass substrate edge detection system to remind the staff.

[0025] Based on the above settings, the present utility model can be installed in the existing glass substrate edge detection system without changing the existing production line layout and without replacing the equipment in the existing glass substrate edge detection system, so as to realize the integrity positioning detection of the glass substrate 100, ensure the accuracy of the positioning detection, effectively detect the problems that will affect the normal progress of the edge detection, enable the staff to intervene in abnormal situations more timely, prevent the detection mechanism 200 from colliding with the glass substrate 100 when moving, resulting in damage to the detection mechanism 200 and fragmentation of the glass substrate 100, extend the service life of the detection mechanism 200, and avoid the situation of stopping the machine due to cleaning broken glass, thereby improving the equipment utilization rate. Specifically, when there is an abnormal situation with the glass substrate 100, the processing duration required for timely intervention is about 5 minutes. When a collision occurs, the duration for cleaning the glass fragments is about 40 minutes. Calculated according to the frequency of abnormal situations being 2 times a day, the daily saved production duration is 70 minutes. In an ideal state, the equipment utilization rate can be increased by 1.94% per day.

[0026] In the induction assembly 21, the connection line between the induction ends of the two induction units 211 is inclined with respect to the conveying direction of the glass substrate 100. Since in order to ensure the detection accuracy of the detection mechanism 200, the distance between its moving and the edge of the glass substrate 100 is relatively small, the safe distance is also relatively small, for example, 5 mm. As Figure 1 and Figure 3As shown, based on the settings of the present utility model, when the distance 212 between the sensing ends of the two sensing units 211 in the sensing component 21 meets the safety distance requirement along the conveying direction of the glass substrate 100, the actual distance between the two sensing units 211 is made larger, reducing the signal interference between the two sensing units 211.

[0027] Two or more of the sensing components 21 are provided, and the two or more sensing components 21 are arranged along the conveying direction of the glass substrate 100. Each individual sensing component 21 is correspondingly adapted to a single size specification of the glass substrate 100, so as to increase the applicable range of the present utility model and enable it to be applicable to glass substrates 100 of multiple size specifications.

[0028] Specifically, three sensing components 21 are provided, which can be adapted to three models of glass substrates 100, such as glass substrates 100 of the three models G8.5 / G8.6 / G8.7. The length dimensions of the glass substrates 100 of these three models are 2500mm / 2600mm / 2620mm.

[0029] Taking the three models G8.5 / G8.6 / G8.7 as an example, when only one set of sensing components 21 is used to participate in the detection for a specific model of glass substrate 100, the preset detection mode in specific applications is as follows:

[0030] ① When the production line is for the G8.5 glass substrate 100, Figure 3 The first set of sensing components 21 from left to right works. Under normal conditions, the right edge of this glass substrate 100 is located between the two sensing units 211 in this first set of sensing components 21, showing one on and one off. When both are off, it is an abnormal state.

[0031] ② When the production line is for the G8.6 glass substrate 100, Figure 3 The second set of sensing components 21 from left to right works. Under normal conditions, the right edge of this glass substrate 100 is located between the two sensing units 211 in this second set of sensing components 21, showing one on and one off. When both are off, it is an abnormal state.

[0032] ③ When the production line is for the G8.7 glass substrate 100, Figure 3 The third set of sensing components 21 from left to right works. Under normal conditions, the right edge of this glass substrate 100 is located between the two sensing units 211 in this third set of sensing components 21, showing one on and one off. When both are off, it is an abnormal state.

[0033] Taking the three models G8.5 / G8.6 / G8.7 as an example, when all the sensing components 21 of a specific model of glass substrate 100 participate in the detection, the preset detection mode in specific applications is as follows:

[0034] ① When the production line is for the G8.5 glass substrate 100, in the normal state, on the right edge of the glass substrate 100 Figure 3 between the first sensing unit 211 and the second sensing unit 211 from left to right, all the sensing units 211 have one light and five offs in total. When there are six offs, it is an abnormal state.

[0035] ② When the production line is for the G8.6 glass substrate 100, in the normal state, on the right edge of the glass substrate 100 Figure 3 between the third sensing unit 211 and the fourth sensing unit 211 from left to right, all the sensing units 211 have three lights and three offs in total. Otherwise, it is an abnormal state.

[0036] ① When the production line is for the G8.7 glass substrate 100, in the normal state, on the right edge of the glass substrate 100 Figure 3 between the fifth sensing unit 211 and the sixth sensing unit 211 from left to right, all the sensing units 211 have five lights and one off in total. Otherwise, it is an abnormal state.

[0037] The present utility model further includes a mounting seat 3. The length direction of the mounting seat 3 is the same as the conveying direction of the glass substrate 100. The sensing units 211 in two or more of the sensing assemblies 21 are all arranged on the mounting seat 3 to facilitate the installation of all the sensing units 211. The mounting seat 3 can be a rod or aluminum material.

[0038] Two sensing units 211 in a single sensing assembly 21 are correspondingly arranged on both sides of the mounting seat 3, or two sensing units 211 in a single sensing assembly 21 are located on the same side of the mounting seat 3 and the sensing ends of the two sensing units 211 have a spacing two in the width direction of the mounting seat 3. To ensure that when the spacing one 212 between the sensing ends of the two sensing units 211 in the sensing assembly 21 along the conveying direction of the glass substrate 100 meets the safety distance requirement, there is a larger actual distance between the two sensing units 211.

[0039] The present utility model further includes a bracket 4. The number of the brackets 4 corresponds to the number of the sensing units 211. A single sensing unit 211 is arranged on the mounting seat 3 through a single bracket 4 to facilitate setting the sensing unit 211 on the mounting seat 3 and controlling the distance between adjacent sensing units 211.

[0040] The bracket 4 is Z-shaped. The lower end is used to connect with the mounting base 3, and the upper end is used to set the sensing unit 211. The lower end of the bracket 4 is provided with a fixing hole 41 and a kidney-shaped hole 42. The length direction of the kidney-shaped hole 42 is arranged along the width direction of the bracket 4. The fixing hole 41 is located on one side of the long side of the kidney-shaped hole 42. The upper end of the bracket 4 is provided with a plurality of mounting holes 43. Two bolts are respectively passed through the fixing hole 41 and the kidney-shaped hole 42 and then connected with the mounting base 3. The setting of the kidney-shaped hole 42 can provide a certain adjustable angle for the bracket 4, improving the angle adjustability of the sensing unit 211. The mounting holes 43 are for the fixing of the sensing unit 211, and the plurality of mounting holes 43 facilitate the adjustment of the position when the sensing unit 211 is fixed.

[0041] The present utility model further provides a glass substrate edge detection system, and the glass substrate edge detection system is provided with the glass substrate edge positioning device as described above. It realizes the integrity positioning detection of the glass substrate 100, ensures the accuracy of the positioning detection, effectively detects the problems that will affect the normal progress of the edge detection, enables the staff to intervene in the abnormal situation more timely, prevents the problem that the detection mechanism 200 is damaged and the glass substrate 100 is broken when the detection mechanism 200 moves and impacts the glass substrate 100, prolongs the service life of the detection mechanism 200, and avoids the situation of machine stop due to cleaning the broken glass, improving the equipment utilization rate.
