Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass production technology and relates to processing equipment for glass substrate semi-finished products, specifically a glass substrate edge length detection device. Background Technology
[0002] The semi-finished product processing step is a crucial component of LCD glass substrate production. This step primarily involves the transverse segmentation, robot loading, weighing, longitudinal segmentation, cooling, thickness measurement, automatic inspection, manual sampling, sorting, and unloading of the glass after it flows from the muffle furnace. The process involves conveying, weighing, longitudinally segmenting, sorting, packaging, and feeding the formed, pulled-down glass sheets (after transverse segmentation) into the grinding process. Variations in the glass sheet length significantly impact the longitudinal segmentation of the semi-finished product; therefore, data collection on the length of the cut glass edge plates is essential for adjusting the longitudinal segmentation and other processes.
[0003] Currently, the data on the length of the glass substrate edge plate is collected by manually taking edge plates at intervals for measurement and recording. This greatly affects production, and the relevant cutting process cannot obtain edge plate change data and make adjustments in a timely manner, which affects product quality. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a glass substrate edge length detection device, which can acquire the relevant length data of the edge of the glass substrate immediately after the glass substrate is cut.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A glass substrate edge length detection device, comprising:
[0007] Multiple laser sensors are mounted on the breaking mechanisms on both sides of the glass substrate longitudinal slicing machine via support components to detect the edge position data of the glass substrate after it is broken in real time.
[0008] The data processing module is connected to multiple laser sensors to receive data collected by the laser sensors, process and analyze the data, and calculate the edge length of the glass substrate.
[0009] The display module communicates with the data processing module to visually display the length data, statistics, and trend charts of the glass substrate edge.
[0010] Furthermore, it also includes an alarm module, which is connected to the data processing module and can be configured with an alarm function. When the edge length data of the glass substrate is detected to exceed the preset range, an audible and visual alarm will be issued.
[0011] Furthermore, the support assembly includes a guide rail and multiple slides. The guide rail is installed on one side of the suction cup frame of the breaking mechanism. The glass substrate is adsorbed and fixed on the suction cup frame. The guide rail is arranged along the length of the glass substrate. Multiple slides are slidably connected to the guide rail. Multiple laser sensors are installed on the multiple slides one by one to ensure that the laser sensors can move to cover the entire upper and lower edges of the glass substrate.
[0012] Furthermore, the slide block has a groove that matches the guide rail, and the slide block engages with the guide rail through the groove, thus slidingly connecting with the guide rail.
[0013] Furthermore, a drive wheel and a driven wheel are respectively installed on the side walls of the slide. The drive wheel is driven and connected to the servo motor through the drive wheel shaft, and the driven wheel is rotatably connected to the slide through the driven wheel shaft. Two guide grooves are opened on both sides of the guide rail to match the drive wheel and the driven wheel respectively. The guide grooves are arranged along the direction of the guide rail, and the drive wheel and the driven wheel are respectively rolled and connected in the two guide grooves.
[0014] Furthermore, friction strips are provided on the sidewall of the guide groove where it rolls into contact with the driving / driven wheel, and the friction strips are arranged along the guide groove.
[0015] Furthermore, a pressure plate is provided inside the chute, and the pressure plate is connected to the telescopic cylinder via a pressure rod.
[0016] Furthermore, a friction plate is provided on the side wall opposite to the pressure plate of the chute.
[0017] The beneficial effects of this utility model are as follows: The glass substrate edge length detection device provided in this application is installed on the two side breaking mechanisms of the glass substrate longitudinal slicing machine. It uses multiple laser sensors to detect the edge position data of the glass substrate after it is broken in real time, and sends the edge position data of each glass substrate after cutting to the data processing module for analysis and processing. The edge length data of the glass substrate is calculated and displayed on the monitoring screen. This application will not affect the glass substrate longitudinal slicing machine, and the installed laser sensors will not come into contact with the glass substrate, thus not damaging the surface of the glass substrate. The installation is simple, which can greatly improve the detection effect and provide data source for timely adjustment of the corresponding process. When the edge length data of the glass substrate exceeds the warning value or the difference between the edge length data of the two sides is large, an alarm will be triggered immediately.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-2 As shown, this utility model provides a glass substrate edge length detection device, including: three laser sensors 10, a data processing module, a display module, and an alarm module.
[0024] Three laser sensors 10 are mounted on the breaking mechanisms on both sides of the glass substrate slitting machine via support components 20, for real-time detection of the edge position data of the glass substrate after it has been broken. The laser sensors 10 are high-precision laser sensors; their emitted laser beams can accurately capture the contour of the glass substrate edge. The laser sensors feature high resolution and fast response, enabling them to accurately acquire edge position data after the glass substrate is broken. The support components 20 are adaptively installed according to the overall layout of the glass substrate production line to ensure the stability of the entire detection device. The support components 20 are made of robust and durable materials, possessing good shock resistance and anti-interference properties.
[0025] The data processing module communicates with multiple laser sensors 10 to receive data collected by the three laser sensors 10, processes and analyzes the data, and calculates the edge length of the glass substrate. The data processing module processes and analyzes the edge position data of the glass substrate through a preset computer program to calculate the edge length data. The computer program can use existing image processing software and edge detection algorithms. The display module communicates with the data processing module to visually display the edge length data, statistical information, and trend charts of the glass substrate. The display module can be a monitoring screen. The alarm module communicates with the data processing module and can be set to have an alarm function. When the edge length data of the glass substrate is detected to exceed the preset range, an audible and visual alarm is issued to remind the operator to adjust the process parameters in time. The data processing module, display module, and alarm module can be installed in the control room or other convenient locations.
[0026] like Figure 3-4 As shown, the support assembly 20 includes a guide rail 1 and three slide blocks 2. The guide rail 1 is installed on one side of the suction cup frame 30 of the breaking mechanism. The glass substrate 40 is adsorbed and fixed on the suction cup frame 30. The guide rail 1 is arranged along the length of the glass substrate 40. The three slide blocks 2 are slidably connected to the guide rail 1 and can move along the direction of the guide rail 1. Three laser sensors 10 are installed one-to-one on the three slide blocks 2 to ensure that the laser sensors 10 can move to cover the entire upper and lower edge range of the glass substrate 40 and collect edge position data of the glass substrate 40 after it is broken. The support assembly 20 can also be customized according to the actual situation of the glass substrate production line to ensure that the detection device can be easily installed and debugged.
[0027] The slide block 2 has a groove 21 that matches the guide rail 1. The slide block 2 is engaged with the guide rail 1 through the groove 21 and is slidably connected to the guide rail 1. A drive wheel 221 and a driven wheel 222 are respectively installed on the side walls of the groove 21. The drive wheel 221 is driven and connected to the servo motor 23 through the drive wheel shaft 223. The driven wheel 222 is rotatably connected to the slide block 2 through the driven wheel shaft 224. Two guide grooves 11 are provided on both sides of the guide rail 1, which are adapted to the drive wheel 221 and the driven wheel 222 respectively. The guide grooves 11 are arranged along the direction of the guide rail 1. The drive wheel 221 and the driven wheel 222 are tumbled and connected in the two guide grooves 11 respectively. The slide 21 is equipped with a pressure plate 24. The pressure plate 24 is driven and connected to the telescopic cylinder 26 through the pressure rod 25. When the slide 2 moves to the designated position on the guide rail 1, the telescopic cylinder 26 drives the pressure plate 24 to press against the guide rail 1 through the pressure rod 25, fixing the position of the slide 2, so that the laser sensor 10 can collect data.
[0028] Friction strips 12 are provided on the side wall of the guide groove 11 where the driving wheel 221 / driven wheel 222 rolls into contact. The friction strips 12 are arranged along the guide groove 11 and have a rough surface or a surface with evenly distributed patterned protrusions to increase the static friction between the driving wheel 221 / driven wheel 222 and the guide groove 11, thus preventing the driving wheel 221 / driven wheel 222 from slipping in the guide groove 11. A friction plate 13 is provided on the side wall of the slide groove 21 opposite to the pressure plate 24. The friction plate 13 has a rough surface or a surface with evenly distributed patterned protrusions to increase the static friction between the pressure plate 24 and the friction plate 13.
[0029] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
