Description

Technical Field

[0001] The utility model relates to the field of glass substrate production, and in particular to an air knife adjustment system for glass substrate processing. Background Art

[0002] After the glass substrate is processed, the surface must be cleaned to remove surface stains and particles to ensure the cleanliness of the glass. Currently, the cleaning process still uses ultrapure water for rinsing. Therefore, after cleaning and before inspection, the glass must be cleaned with an air knife. High-pressure air is used to blow away the water stains on the glass. However, the drying of water stains is affected by many factors (glass conveying speed, air knife pressure, the distance between the air knife blowing port and the glass, the angle between the air blown by the air knife and the glass, etc.). At present, most air knives cannot be adjusted. For example, a liquid crystal glass drying device with announcement number CN213570200U also requires manual adjustment. Therefore, the adjustment is very cumbersome and difficult, the cycle is relatively long, and the efficiency is low. Utility Model Content

[0003] The purpose of this utility model is to provide a wind knife adjustment system for glass substrate processing, which controls the lifting and rotation of the wind knife through a lifting motor and a rotating motor to remove water stains in all directions and at multiple angles; reduces the wind knife adjustment cycle, improves the adjustment efficiency, and increases the level of automation.

[0004] The utility model is realized through the following technical solutions:

[0005] A wind knife adjustment system for glass substrate processing includes a symmetrically arranged mounting frame, with lifting mechanisms symmetrically provided at the upper and lower ends of each side of the mounting frame, the lifting mechanism driving a rotating mechanism to move up and down, the rotating mechanism including a rotating motor and a lifting seat, the rotating motor being mounted on the lifting seat, and the lifting mechanism driving the lifting seat to move up and down; the system also includes an upper wind knife and a lower wind knife, both ends of which are connected to a rotating shaft, the rotating shafts of the upper wind knife and the lower wind knife being rotatably mounted in the lifting seats on both sides, and the rotating shafts and the rotating motor are connected by a reduction assembly; an opening is provided in the middle of the mounting frame for the rotating shaft to move up and down.

[0006] Furthermore, the lifting mechanism includes a lifting motor symmetrically arranged at the upper and lower ends of the lifting seat and a slide rail arranged on the lifting seat. The lifting motor is connected to the lifting screw through a coupling. The lifting seat is also provided with a connecting plate. The lifting screw is connected to the connecting plate through a screw nut. The lifting seat is slidably installed on the slide rail.

[0007] Furthermore, the deceleration assembly includes a helical gear I and a helical gear II, wherein the helical gear I is mounted on the output shaft of the rotating motor, and the helical gear II is mounted on the rotating shafts of the upper air knife and the lower air knife, respectively. Deceleration is achieved by designing the ratio of the diameter and the number of teeth between the helical gear I and the helical gear II. The use of helical gear transmission can save installation space without changing the original structure of other positions of the equipment.

[0008] Furthermore, it also includes a visual inspection system and a PLC controller. The visual inspection system uses an industrial CCD camera, and the PLC controller is respectively connected to the control operation screen, each rotating motor and each lifting motor. The industrial CCD camera first takes a picture, and then the visual inspection system analyzes the picture. When water stain defects are detected on the glass, the analysis defect signal is transmitted to the PLC controller, and then the relative position and angle of the upper air knife and the lower air knife are changed to blow dry the water stains on the glass.

[0009] Furthermore, the rotating shafts of the upper air knife and the lower air knife are connected to the lifting seat through bearings.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. Speed reduction is achieved by designing the ratio of the diameter and number of teeth between helical gears I and II. The use of helical gear transmission can save installation space without changing the original structure of other parts of the equipment.

[0012] 2. The lifting and rotation of the air knife are controlled by the lifting motor and the rotating motor to remove water stains in all directions and at multiple angles; this reduces the air knife adjustment cycle, improves adjustment efficiency, and increases the level of automation.

[0013] 3. Achieve automation by cooperating with the visual inspection system. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figure 2As shown, a wind knife adjustment system for glass substrate processing includes a symmetrically arranged mounting frame 11, and lifting mechanisms are symmetrically provided at the upper and lower ends of each side of the mounting frame 11. The lifting mechanism drives the rotating mechanism to move up and down. The rotating mechanism includes a rotating motor 3 and a lifting seat 7. The rotating motor 3 is installed on the lifting seat 7, and the lifting mechanism drives the lifting seat 7 to move up and down; it also includes an upper wind knife 8 and a lower wind knife 9, and both ends of the upper wind knife 8 and the lower wind knife 9 are connected to a rotating shaft. The rotating shafts of the upper wind knife 8 and the lower wind knife 9 are respectively rotatably installed in the lifting seats 7 on both sides, and the rotating shafts and the rotating motor 3 are connected by a reduction assembly; an opening is provided in the middle position of the mounting frame 11 for the rotating shaft to move up and down.

[0020] Example 2

[0021] A wind knife adjustment system for glass substrate processing, the lifting mechanism includes a lifting motor 1 symmetrically arranged at the upper and lower ends of a lifting seat 7 and a slide rail 10 arranged on the lifting seat 7, the lifting motor 1 is connected to the lifting screw 2 through a coupling, the lifting seat 7 is also provided with a connecting plate 6, the lifting screw 2 is connected to the connecting plate 6 through a screw nut, and the lifting seat 7 is slidably mounted on the slide rail 10; the deceleration assembly includes a helical gear I4 and a helical gear II5, the helical gear I4 is mounted on the output shaft of the rotating motor 3, the helical gear II5 is respectively mounted on the rotating shafts of the upper wind knife 8 and the lower wind knife 9, the helical gear Gear I4 meshes with helical gear II5. Speed reduction is achieved by designing the diameter and tooth number ratio between helical gears I4 and II5. The use of helical gear transmission saves installation space and does not alter the existing structure of other parts of the equipment. The system also includes a visual inspection system and a PLC controller. The visual inspection system utilizes an industrial CCD camera. The PLC controller is connected to a control panel, each rotating motor 3, and each lifting motor 1, allowing parameters to be set via the control panel. The rotating shafts of the upper and lower air blades 8 and 9 are connected to the lifting base 7 via bearings. All other aspects are the same as those of Example 1. The visual inspection system and other related features are prior art and are not described in detail here.

[0022] like Figure 1 As shown, the glass 12 is first photographed by an industrial CCD camera, and then the visual inspection system analyzes the photo. When water stain defects are detected on the glass, the analysis defect signal is transmitted to the PLC controller, and then the PLC controller controls the lifting motors 1 at the upper and lower ends respectively to adjust the distance between the upper air knife 8 and the lower air knife 9. According to the situation of water stain removal, the PLC controller controls the rotating motor 3 to adjust the angles of the upper air knife 8 and the lower air knife 9 relative to the glass 12 to perform efficient drying until the water stains on the glass are dried.

[0023] When installing and debugging the air knife, first set the air knife outlet 10mm from the glass as the origin. Adjust the distance between the air knife and the glass in 5mm increments (adjustment range 50mm). Adjust the air knife in 5° increments each time it rises until it reaches 45 degrees. If the water stain is eliminated and the visual inspection system no longer issues a defect signal, the air knife's position, height, and angle remain fixed and no further adjustments are required. If the water stain persists, continue adjusting the air knife at different heights and angles until the stain disappears.
