Description

Technical Field

[0001] This utility model relates to the field of vertical glass inspection technology, specifically to a vertical glass defect location mechanism. Background Technology

[0002] In the glass industry, defects are inspected at the end of glass production. These defects include scratches, dirt, bubbles, chipping, and other defects that affect the use of the glass.

[0003] Scratches are caused by friction or collision with rollers and molds during the molding process. They can also occur during cutting or handling, such as with diamond tools or jigs that scratch the surface. These leave noticeable linear marks, affecting the appearance. Current detection methods involve observing the surface at an angle under strong light and marking the location of the scratches.

[0004] Dirt is impurities introduced during raw material mixing. Foreign matter is generated during the melting process due to erosion of the kiln refractory material. The detection method involves identifying discolored spots through contrast in a dark environment and marking the location of the scratches.

[0005] Bubbles are caused by incomplete clarification during the melting stage, resulting in incomplete gas removal. The detection method involves visual inspection under transmitted light to observe transparent or translucent spherical defects inside the glass. Edge chipping is detected by touching or visually observing the edge integrity and marking the location of the scratches.

[0006] The above inspection methods cannot pinpoint the location of glass defects. After inspection, the defect location is manually marked and plotted. When multiple defects exist on the glass, it's impossible to effectively locate them, leading to missed defects and impacting production efficiency and product quality. Utility Model Content

[0044] To make the utility model's objectives, features, and advantages more apparent and understandable, specific embodiments and accompanying drawings will be used to clearly and completely describe the technical solution protected by this utility model. Obviously, the embodiments described below are only a part of the embodiments of this utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0045] like Figure 1 and Figure 2 As shown, the vertical glass defect location mechanism provided in this embodiment includes: a detection terminal, a support frame 1, and a vertical glass detection device 5 disposed on one side of the support frame 1. The support frame 1 has three frames connected by a transverse connecting beam. Multiple frames can be installed as needed. Two frames are disposed at both ends of the support frame, and the other is disposed in the middle of the support frame.

[0046] The support frame 1 is designed with a horizontal conveying component 7 and a limiting component, which can smoothly and accurately move the vertical glass horizontally and ensure its stability during the inspection process.

[0047] In some specific embodiments, such as Figure 4 As shown, the limiting component includes a lifting slide 6, which is mounted on both sides of the support frame 1 and can be bolted to the sides of the support frame 1. The lifting slide 6 has a rack, which is connected to a lifting beam 15 via gears. The gears are connected to a lifting motor, enabling flexible height adjustment and driving the lifting beam 15 to move up and down. A photoelectric switch 16 for sensing the position of the vertical glass is mounted on the lifting beam 15; the detection terminal is electrically connected to both the photoelectric switch 16 and the lifting motor. Optionally, the lifting beam 15 has a built-in pulley to prevent friction between the glass and the lifting beam 15. When the glass moves to the position of the photoelectric switch 16, it triggers the sensing information, causing the detection terminal to control the lifting motor to stop, facilitating glass positioning.

[0048] Optionally, the lifting beam 15 has a U-shaped structure to prevent the glass from tipping over during the cleaning process. The lifting slide 6 is fixed to the side frames of the support frame 1 by bolts and nuts.

[0049] like Figure 3 As shown, the horizontal conveying assembly 7 in this embodiment is equipped with multiple conveyor wheels 12 and drive wheels 11. The multiple conveyor wheels 12 and drive wheels 11 are respectively fixed to the bottom beam of the support frame 1. A conveyor belt 13 is wound around the multiple conveyor wheels 12 and drive wheels 11. V-blocks 14 are provided on the conveyor belt 13 to prevent the glass 3 from sliding away from the support panel. The glass 3 is placed on the V-blocks 14 of the conveyor belt 13 and moves forward through the friction between itself and the V-blocks 14. A horizontal drive motor is connected to the drive wheels 11, and the detection terminal is electrically connected to the horizontal drive motor.

[0050] It should be noted that the horizontal drive motor is connected to the drive wheel 11 through a coupling and transmits power to the drive wheel 11. The drive wheel 11 and the conveyor belt 13 are driven by friction, and the V-block 14 is fixed on the conveyor belt 13.

[0051] As can be seen, when the glass is placed on the support frame 1, the detection terminal obtains information such as the length and width of the glass, and drives the lifting beam 15 to move to the appropriate height based on the obtained glass height. It can also control the horizontal drive motor to drive the glass forward through the conveyor belt 13. The upper edge of the glass is located in the U-shaped groove of the lifting beam 15, and the photoelectric switch 16 senses the positioning state. When the left edge of the glass moves to the photoelectric switch 16, it stops moving.

[0052] In this embodiment, the horizontal conveying assembly 7 is equipped with a support panel 2 for supporting vertical glass. The support panel 2 is tilted at a certain angle to the ground, which can relatively limit the glass and prevent it from being completely perpendicular to the ground, thus ensuring the safety and stability of the glass throughout the inspection process. Multiple pulleys 4 are provided on the support panel, and the pulleys 4 are fixed to the support panel by clips. This avoids friction between the glass and the support panel, improving the continuity and accuracy of the glass movement.

[0053] like Figure 5 As shown, the glass defect positioning device in this embodiment is provided with multiple defect positioning components. Each defect positioning component is provided with two laser emitters 21, wherein the first laser emitter is located at a first end near the top of the support frame 1, and the second laser emitter is located at a second end near the top of the support frame 1. Each laser emitter is connected to a motor 23 that drives its rotation. Optionally, the motor 23 is fixed to the support frame 1 by an L-shaped plate 22, and the motor and the L-shaped plate 22 and the bracket are respectively connected by bolts. The laser emitter 21 is connected to the motor 23 by a connecting sleeve.

[0054] The detection terminal is electrically connected to the vertical glass detection device 5, the horizontal conveying assembly 7, the laser emitter, and the motor. The detection terminal controls the two laser emitters to initially shoot vertically towards the lower edge of the support panel to obtain the coordinates of the glass defect detected by the vertical glass detection device 5. Based on the coordinates of the glass defect, the required rotation angle of the two motors is calculated. The current angle of the motor is obtained, and the actual rotation angle of the motor is obtained based on the required rotation angle and the current angle. The detection terminal sends a command to the motor to control the motor to rotate, so that the two laser emitters are simultaneously aligned with the glass defect position.

[0055] Optionally, the inspection terminal uses a Siemens S7-1200 PLC terminal or an Advantech UNO-2272G industrial computer. The vertical glass inspection device uses the YG-LD-GD5 type vertical glass defect location and inspection device; it should be noted that YG: usually represents "glass inspection" (Yi Liang Jian Ce, abbreviation of pinyin); LD: represents "laser positioning" (JingGuang Ding Wei, Laser Detection / Positioning); GD: represents "glass" (Bo Li, Glass); 5: model number (indicating the 5th generation or basic model in the series). The ZL-GD-DP5 type vertical glass defect location and inspection device can also be used.

[0056] like Figure 6 As shown, in this embodiment, the motor drives the laser emitter connected by the sleeve, which can rotate to a certain angle, causing the linear lasers emitted by a group of laser emitters to intersect at a point at the defect in glass 3. The intersection point is the defect location, thus completing the localization of the defect in glass 3.

[0057] In this embodiment, when there are multiple glass defect points, the detection terminal controls the two motors in the first defect positioning component to the initial position, so that the laser emitter in the first defect positioning component is perpendicularly directed towards the lower edge of the support panel; the detection terminal obtains the positions of all glass defect points on the glass through the vertical glass detection device 5; the first glass defect point position is retrieved, the rotation angle of the two motors in the first defect positioning component is calculated, and the laser emitter in the first defect positioning component is controlled to align with the first glass defect point position; then the second glass defect point position is retrieved, the rotation angle of the two motors in the second defect positioning component is calculated, and the laser emitter in the second defect positioning component is controlled to align with the second glass defect point position; and so on.

[0058] In some specific embodiments, when multiple sets of defect location components are installed, different laser indicator lights for different sets can be used to indicate defects that can be quickly cleaned manually, such as dirt, using a green laser beam, while defects that cannot be quickly cleaned manually, such as scratches and bubbles, can be indicated using a red laser beam, or other combinations of indication methods.

[0059] The control method in this embodiment can be based on automatic operation, or it can be equipped with interactive tools such as wireless remote control. After manually cleaning or marking the current defect, the laser pointer can be located by pressing the remote control or other interactive tools, and the interface of the detection terminal will simultaneously mark the currently indicated defect.

[0060] In one exemplary embodiment, such as Figure 7 As shown, the preset position at the bottom of the support frame is the origin of the coordinate system, which can be selected as the lower left corner of the glass. The initial position of the laser emitter is perpendicular to the lower edge of the support panel. The detection terminal obtains the coordinates of the first defect 28 in the glass as (l, h), the interval distance between the two defect positioning components is L, and the distance from the defect positioning component to the lower edge of the glass is H. From this, it can be calculated that the first motor 24 needs to rotate counterclockwise by an angle α°, and the second motor 26 needs to rotate clockwise by an angle β°.

[0061]

[0062] .

[0063] L represents the distance between the first motor and the second motor; l It is the horizontal distance from the first motor to the glass defect.

[0064] If the indicator glass has a second defect 29, the first motor 24 needs to rotate α1° relative to its initial position, and the second motor 26 needs to rotate β1° relative to its initial position. Therefore, the actual rotation angle of the left-side motor 24 is α2°, and the actual rotation angle of the second motor 26 is β2°. α2 = α1 - α, β2 = β - β1.

[0065] Figure 8 This is a schematic diagram of two sets of glass defect indicators in this embodiment. Two sets of defect positioning components are provided. The distance between the first motor 24 and the left side motor 25 of the second defect positioning component is x, and the distance between the second motor 26 and the right side motor 27 of the second defect positioning component is also x. When the second defect positioning component points to the first glass defect 28, the left side motor 25 of the second defect positioning component needs to rotate counterclockwise by γ°, and the right side motor 27 of the second defect positioning component needs to rotate clockwise by θ°.

[0066]

[0067] .

[0068] This embodiment of the vertical glass defect location mechanism, by explicitly providing the motor rotation angle calculated based on the glass defect coordinates, enables control of the laser emitter to align with the glass defect position. For example, for defects in different locations, accurate motor rotation angles can be calculated based on specific coordinates and distance parameters, reducing positioning errors and improving positioning accuracy. This embodiment considers the case of multiple defect location components and provides the distance parameters between different components and the corresponding motor rotation angles. The number and layout of defect location components can be set according to actual needs to adapt to the inspection requirements of glass of different sizes and with different defect distributions, improving versatility and adaptability.

[0069] The vertical glass defect positioning mechanism is implemented by controlling two laser emitters to initially shoot vertically towards the lower edge of the support panel. The coordinates of the glass defect detected by the vertical glass inspection device are obtained. Based on the glass defect coordinates, the required rotation angles of the two motors are calculated. The current motor angles are obtained, and the actual rotation angle of the motors is determined based on the required rotation angle and the current angle. The detection terminal sends a command to the motors to control their rotation, so that both laser emitters are simultaneously aligned with the glass defect position.

[0070] As a specific implementation of this embodiment, it also includes: controlling two laser emitters to initially shoot vertically toward the lower edge of the support panel to obtain the coordinates of the glass defect detected by the vertical glass inspection device.

[0071] Based on the coordinates of the glass defect, the required rotation angles of the two motors are calculated.

[0072] Obtain the current angle of the first motor, let the current angle be Ac, and the required rotation angle be Ad. Calculate the difference dA = Ad - Ac.

[0073] Given the current angle of the second motor as Bc and the required rotation angle as Bd, calculate the difference dB = Bd - Bc.

[0074] The detection terminal creates two motor control processes to control the operation of the first motor and the second motor respectively.

[0075] If dA≥0 and dB≥0, then the first motor control process controls the first motor to rotate in the specified direction by the number of steps related to dA; the second motor control process controls the second motor to rotate in the specified direction by the number of steps related to dB.

[0076] If dA≥0 and dB<0, then the first motor control process controls the first motor to rotate in the specified direction for the number of steps related to dA; the second motor control process controls the second motor to first rotate in the reverse direction to reset to the preset origin position, and then rotate in the forward direction to the step counting origin position to start counting steps, and then rotate in the specified direction for the number of steps related to Bd from the step counting origin.

[0077] If dA < 0 and dB ≥ 0, the first motor control process controls the first motor to first rotate in the reverse direction to reset to the preset origin position, and then rotate in the forward direction to the step counting origin position to start counting steps. Starting from the step counting origin, it rotates in the specified direction for the number of steps related to Ad. The second motor control process controls the second motor to rotate in the specified direction for the number of steps related to dB.

[0078] If dA < 0 and dB < 0, the first motor control process controls the first motor to first rotate in the reverse direction to the preset origin position, and then rotate in the forward direction to the step counting origin position to start counting steps. From the step counting origin position, it rotates in the specified direction to count the number of steps related to Ad.

[0079] The second motor control process controls the second motor to first rotate in the reverse direction to the preset origin position, and then rotate in the forward direction to the step counting origin position to start counting steps. Starting from the step counting origin, it rotates in the specified direction to count the steps related to Bd.

[0080] After the detection terminal completes the current motor control process, it waits for the next motor control process.

[0081] In this embodiment, during motor operation, subtle deviations in the mechanical structure and changes in friction may lead to cumulative errors, affecting positioning accuracy. By resetting the motor to a preset origin position and restarting step counting from the origin, these cumulative errors can be effectively eliminated, ensuring that each motor movement is based on an accurate starting point, thereby improving positioning accuracy. This embodiment plans the most suitable motion path for the motor based on different combinations of dA and dB. When the signs of dA and dB are inconsistent, resetting and re-counting steps for one motor allows the motor's movement to better match the actual needs of defect positioning, avoiding positioning deviations caused by unreasonable motion paths.

[0082] When dB and dA have the same sign, the motor is directly controlled to rotate the specified number of steps in the designated direction, reducing motor movement time and energy consumption, and improving system response speed. Taking glass defect location as an example, it can align the laser emitter with the defect location more quickly. Dividing motor control into two independent processes allows for parallel control of the two motors. In complex positioning tasks, the two motors can simultaneously perform actions according to their respective motion strategies, shortening the overall positioning time.

[0083] By acquiring the coordinates of the glass defect and accurately calculating the motor rotation angle, while also making meticulous adjustments to account for the current motor angle, the laser emitter can be more precisely aligned with the glass defect location. Compared to traditional positioning methods, this reduces positioning deviations caused by motor control errors, significantly improving positioning accuracy. For example, it reduces defect positioning errors from the millimeter level to the sub-millimeter level, effectively meeting the demand for high-precision detection and positioning of glass defects.

[0084] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
