Description

Technical Field

[0001] This application belongs to the field of display glass inspection, and specifically relates to a width inspection system for display glass. Background Technology

[0002] During the production of display glass, after the edges are trimmed, a dimensional inspection is required to ensure that the product is qualified before packaging.

[0003] Current methods for inspecting the dimensions of display glass mostly rely on manual sampling, measuring dimensions manually. This approach is not only inefficient but also cannot ensure on-line inspection of all display glass. Uncertainties in preceding cutting processes can easily lead to missed defects, impacting the overall product quality.

[0004] Therefore, a width detection system for linear display glass is needed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a display glass width detection system that can be directly installed on both sides of the display glass transmission mechanism to perform on-line detection of the passing display glass, greatly improving measurement efficiency and ensuring the pass rate of the display glass.

[0006] The technical effect to be achieved in this application is accomplished through the following solution:

[0007] According to a first aspect of this application, a width detection system for display glass is provided, comprising a display glass transmission mechanism, mounting frames mounted on both sides of the display glass transmission mechanism, a measuring frame rotatably connected to the mounting frames via torsion springs, the torsion springs always applying a force toward the center of the display glass transmission mechanism to the measuring frame; mounting plates are provided on the top of each measuring frame, one of the mounting plates being equipped with a laser rangefinder; the measuring frame includes a pressure rod assembly and a pressure plate, the pressure rod assembly including a plurality of pressure rods, one end of each pressure rod being elastically connected to the mounting frame via the torsion springs, and the other end of each pressure rod being rotatably connected to the center of the pressure plate.

[0008] In this solution, as the display glass passes through, the measuring frame presses against both sides of the display glass to accommodate its width. After the measuring frame is clamped, a laser rangefinder measures the distance, which is the current width of the display glass. At a subsequent station, a rotation mechanism can be installed to rotate the display glass 90 degrees and measure again. The pressure bar always presses the pressure plate against the display glass, and the pressure plate can adapt to and align the tilted display glass, keeping it parallel to the pressure plate and ensuring accurate dimensional measurement by the laser rangefinder.

[0009] Preferably, the front end of the pressure plate is bent toward the mounting bracket to form a guide portion.

[0010] With this solution, the guide section can adapt to display glass of different widths and positions, avoiding collision between the front end of the pressure plate and the display glass.

[0011] Preferably, a fine-tuning plate is provided on another mounting plate, the fine-tuning plate being threadedly connected to the mounting plate.

[0012] This design allows the fine-tuning plate to be adjusted forward and backward, thereby compensating for positional errors in the mounting frame or measuring frame and improving the detection accuracy of the device.

[0013] Preferably, the bottom of the pressure plate is clearance-fitted with the surface of the display glass transmission mechanism, and a nylon strip is connected to the bottom of the outer side of the pressure plate.

[0014] This solution protects the sides of the display glass from scratches and reduces friction.

[0015] Preferably, the bottom of the pressure plate is bent outward and upward to form a connecting part, and the bottom of the nylon strip is provided with a mounting groove that matches the connecting part. The mounting groove is inserted into the connecting part to complete the connection.

[0016] This solution makes it easy to replace the nylon strip; simply plug it in and unplug it.

[0017] Preferably, the surface of the connecting part is bent with several raised strips.

[0018] This design increases the friction between the raised strip and the mounting groove, ensuring the nylon strip is securely installed.

[0019] Preferably, the pressure bar assembly includes two pressure bars of the same length, which together with the pressure plate and the mounting bracket form a parallelogram.

[0020] With this solution, the pressure bar can ensure that the angle of the pressure plate remains stable and parallel to the mounting bracket, thus ensuring that it can be clamped to both sides of the display glass and the width can be measured after it is aligned.

[0021] According to one embodiment of this application, the beneficial effect of using the width detection system for display glass is that it can detect the size of the display glass in real time without stopping the display glass, which greatly improves the detection efficiency; moreover, it can detect each piece of display glass, avoiding the failure rate caused by missed detection.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figures 1 to 5 As shown, in one embodiment of this application, the width detection system for display glass includes a display glass transmission mechanism 400. Mounting brackets 100 are installed on both sides of the display glass transmission mechanism 400. A measuring frame 200 is rotatably connected to the mounting bracket 100 via a torsion spring. The torsion spring always applies a force to the measuring frame 200 toward the center of the display glass transmission mechanism 400. A mounting plate 222 is provided on the top of each measuring frame 200, and a laser rangefinder 310 is provided on one of the mounting plates 222.

[0030] In one embodiment of this application, the measuring frame 200 includes a pressure rod assembly and a pressure plate 220. The pressure rod assembly includes a plurality of pressure rods 210, and one end of the pressure rod 210 is elastically connected to the mounting frame 100 through the torsion spring. The other end of the pressure rod 210 is rotatably connected to the middle of the pressure plate 220. The pressure rod 210 can always press the pressure plate 220 onto the display glass. The pressure plate 220 can adapt to the tilted display glass and straighten it, so that the display glass and the pressure plate 220 remain parallel, ensuring that the laser rangefinder 310 can accurately measure the size.

[0031] In one embodiment of this application, the pressure bar assembly includes two pressure bars 210 of equal length. The pressure bars 210, together with the pressure plate 220 and the mounting bracket 100, form a parallelogram. The pressure bars 210 ensure that the angle of the pressure plate 220 remains stable and parallel to the mounting bracket, thereby ensuring that it can be clamped to both sides of the display glass and its width can be measured after it is aligned.

[0032] The laser rangefinder 310 can also be an ultrasonic rangefinder or other similar device, capable of accurately detecting distance, which is the size of the display glass.

[0033] In this embodiment, when the display glass passes through, the measuring frame 200 is pressed against both sides of the display glass to accommodate the width of the display glass. After the measuring frame 200 is clamped, the laser rangefinder 310 measures the distance between it and another mounting plate 222, which is the current width of the display glass.

[0034] In a subsequent workstation, a rotating mechanism can be set to rotate the display glass 90 degrees, and then the same mechanism can be set up again to measure the size of the display glass, thus completing the size measurement of the display glass.

[0035] In one embodiment of this application, the front end of the pressure plate 220 is bent toward the mounting bracket 100 to form a guide portion 221. The guide portion 221 can adapt to display glass of different widths and positions, avoiding collision between the front end of the pressure plate 220 and the display glass.

[0036] In one embodiment of this application, a fine-tuning plate 320 is provided on another mounting plate 222, and the fine-tuning plate 320 is threadedly connected to the mounting plate 222. The fine-tuning plate 320 can be adjusted back and forth, thereby compensating for the positional error of the mounting frame 100 or the measuring frame 200 and improving the detection accuracy of the device.

[0037] In one embodiment of this application, the bottom of the pressure plate 220 is in clearance fit with the surface of the display glass transfer mechanism 400, and a nylon strip 230 is connected to the bottom of the outer side of the pressure plate 220. The nylon strip 230 can protect the side of the display glass, preventing scratches on the side of the display glass, and the nylon strip 230 can reduce friction.

[0038] In one embodiment of this application, the bottom of the pressure plate 220 is bent outward and upward to form a connecting portion 223. The connecting portion 223 has a U-shaped structure. The bottom of the nylon strip 230 is provided with a mounting groove 231 that matches the connecting portion 223. The mounting groove 231 is inserted into the connecting portion 223 to complete the connection. Since the edge of the display glass will cause significant wear to the nylon strip 230, resulting in a decrease in measurement accuracy, this solution facilitates the replacement of the nylon strip 230 by simply plugging and unplugging it.

[0039] In one embodiment of this application, the surface of the connecting portion 223 is bent with a plurality of raised strips 224. The raised strips 224 can increase the friction between the connecting portion 223 and the mounting groove 231, ensuring the firmness of the nylon strip 230 installation.

[0040] The pressure plate 220 is made of galvanized sheet or steel sheet, and is manufactured by bending machine or stamping machine. It has high strength and is easy to bend and form.

[0041] According to one embodiment of this application, the beneficial effect of using the width detection system for display glass is that it can detect the size of the display glass in real time without stopping the display glass, which greatly improves the detection efficiency; moreover, it can detect each piece of display glass, avoiding the failure rate caused by missed detection.
