[0033] The main purpose of the present invention is to provide a glass thickness detection device with multiple probes, aiming to solve the problem of how to improve the efficiency of glass thickness detection. Figures 1 to 3 As shown, the present invention proposes a multi-probe glass thickness detection device, comprising: a glass conveying device 1, a guide rail 2, a plurality of guide rail driving devices 3, a plurality of thickness detection devices 4, a control device, a distance detection device 15, a glass driving device, a display device 6 and an electric control box 5. Glass 11 is arranged on the glass conveying device 1, and the glass conveying device 1 is used to drive the glass 11 to move. The guide rail 2 is arranged above the glass conveying device 1, and a plurality of guide rail driving devices 3 are connected to the guide rail 2 for moving along the guide rail 2. A plurality of thickness detection devices 4 are respectively connected to the plurality of guide rail driving devices 3 to detect the thickness data of different areas of the moving glass 11. The control device is connected to the thickness detection device 4, and the control device is used to control the movement of the guide rail driving device 3, and send the thickness data detected by the thickness detection device 4 to a glass thickness processing device for processing the glass 11, so that the glass thickness processing device can adjust the processing parameters. Specifically, the glass thickness processing device includes a calendering roller, and the thickness of different areas of the glass 11 is adjusted by controlling the position of the calendering roller.

[0034] Furthermore, the thickness detection device 4 includes a spectral confocal sensor and a controller. The spectral confocal sensor is connected to the controller. The spectral confocal sensor is used to detect thickness data. The controller is used to collect the thickness data detected by the spectral confocal sensor to obtain the thickness values ​​of different areas of the glass 11. Specifically, the controller has a built-in microprocessor responsible for collecting data from the three measuring heads. The controller transmits the obtained data to the industrial computer, and the industrial computer processes the data through an algorithm to obtain the thickness value of the glass 11. The industrial control computer (Industrial Control Computer) is a computer device specially designed for use in industrial control systems. Exemplarily, the industrial computer is set in the electric control box 5, and the control device is connected to the three spectral confocal sensors respectively. The controller transmits the collected data from the three spectral confocal sensors to the industrial computer, and the industrial computer processes the data through an algorithm to obtain the thickness value of the glass 11.

[0035] As an embodiment, the glass conveying device 1 includes a bracket 9 and a roller 8, and the bracket 9 is connected to the roller 8 to support the roller 8. Specifically, the bottom of the bracket 9 is supported on the ground, and a plurality of rollers 8 are arranged on the bracket 9. The number of rollers 8 can be set according to the needs of the user, and the plurality of rollers 8 are evenly spaced and horizontally arranged along the conveying direction of the glass 11. The glass 11 is arranged on the roller 8 so as to move in the horizontal direction under the rolling of the roller 8. Each roller 8 is provided with a plurality of evenly spaced rubber wheels. When the glass conveying device 1 conveys large-sized glass 11, the rubber wheels can absorb the vibration generated by the roller 8 to prevent the large-sized glass 11 from being damaged during the conveying process. At the same time, the rubber wheels can increase the friction with the glass 11 to prevent the glass 11 from being scratched during the conveying process.

[0036] Furthermore, the glass drive device is connected to the roller 8, and is used to drive the roller 8 to rotate at a preset speed, so that the moving speed of the glass 11 is less than or equal to 500 mm / s. At this speed, the thickness detection device 4 can accurately detect the thickness of the glass 11 and reduce the error. Specifically, the glass drive device can be an AC asynchronous motor, which is simple and reliable, has low maintenance cost, and has a large starting torque and a stable speed. The glass drive device can also be other motors, such as a stepper motor.

[0037] As an embodiment, the electric control box 5 is arranged on one side of the glass conveying device 1, a column is arranged on the other side of the glass conveying device 1, the crossbeam 12 is respectively connected to the column 16 and the electric control box 5, and the guide rail 2 is arranged on the crossbeam 12 to be erected above the glass conveying device 1. In other embodiments, columns 16 are respectively arranged on both sides of the glass conveying device 1, the crossbeam 12 is respectively connected to the columns 16 on both sides of the glass conveying device 1, and the guide rail 2 is arranged on the crossbeam 12 to be erected above the glass conveying device 1. Further, the sliding direction of the guide rail 2 is perpendicular to the conveying direction of the glass 11.

[0038] As an embodiment, the control device is located in the electric control box 5. The control device can be a computer, a processor, a microcontroller or a single-chip microcomputer, etc., which is a chip or device for data processing and control. The electric control box 5 can protect the control device. The shell of the electric control box 5 can be made of metal material or plastic. The electric control box 5 is connected to an external power supply for powering the device in the glass thickness detection setting. The external power supply can be AC ​​power or power generated by other external devices. Further, the glass drive device is connected to the control device for driving the cylinder to rotate at a preset speed under the control of the control device so that the moving speed of the glass 11 is less than or equal to 500 mm / s. Exemplarily, the preset speed is less than or equal to 500 mm / s, and the glass drive device is powered by the external power supply in the electric control box 5.

[0039] As an implementation mode, each guide rail driving device 3 is connected to the control device and is used to move to different areas under the control of the control device. Specifically, a total of three guide rail driving devices 3 are arranged on the guide rail 2, and each guide rail driving device 3 is connected to the control device and is used to move to different areas under the control of the control device to detect the thickness of the glass 11 in different areas during the conveying process. The guide rail driving device 3 can be a cylinder or a motor, and is used to move along the guide rail 2 under the control of the control device.

[0040] Furthermore, the control device is also connected to an external cutting device for cutting the glass 11, and is used to move the three guide rail driving devices 3 to different areas of the glass 11 cut by the external cutting device under the control of the external cutting device. Specifically, the external cutting device can be a laser cutting device or a water jet cutting device. When the glass 11 is a large-sized glass 11, it needs to be cut. The external cutting device cuts the large-sized glass 11 according to the cutting method preset by the user, and cuts the large-sized glass 11 into glass 11 of different areas. It should be noted that the number of guide rail driving devices 3 and thickness detection devices 4 corresponds to the number of different areas of the glass 11 in the transverse direction. For example, when the glass 11 is cut into three different areas in the transverse direction, the number of guide rail driving devices 3 and thickness detection devices 4 is 3, so as to quickly detect the thickness of different areas. The control device is connected to the external cutting device, obtains the data in the external cutting device, and controls the guide rail driving devices 3 to move to different areas above the glass 11 in the transverse direction. Before cutting the large-sized glass 11, the thickness of each piece of glass 11 after cutting can be obtained.

[0041] As an implementation method, Figure 4As shown, the guide rail drive device 3 includes a first drive device 13 and a second drive device 14, the first drive device 13 is arranged on the guide rail 2, the second drive device 14 is arranged on the first drive device 13, the thickness detection device 4 is arranged on the second drive device 14, and the second drive device 14 is connected to the control device, and is used to move in a direction away from or close to the glass 11 under the control of the control device. Specifically, the first drive device 13 and the second drive device 14 can be cylinders or motors, and the second drive device 14 is preferably a servo motor. The first drive device 13 is connected to the control device, and is used to move along the guide rail 2 under the control of the control device.

[0042] Further, the distance between the distance detection device 15 and the glass 11 is equal to the distance between the thickness detection device 4 and the glass 11. The distance detection device 15 is connected to the control device and is used to detect the distance between the thickness detection device 4 and the glass 11, so that the glass 11 scratches the thickness detection device 4 when the glass 11 explodes. Specifically, the control device is used to detect the size of the distance between the thickness detection device 4 and the glass 11 and the preset distance, so as to control the second drive device 14 to move in the direction close to the glass 11 when the distance between the thickness detection device 4 and the glass 11 is greater than the preset distance, and control the second drive device 14 to move in the direction away from the glass 11 when the distance between the thickness detection device 4 and the glass 11 is less than the preset distance. In a specific embodiment, the distance detection device 15 is arranged beside the thickness detection device 4 and is arranged parallel to the thickness detection device 4, and the preset distance is 80 mm, so that the thickness detection device 4 always maintains a certain distance from the glass 11, which can increase the detection accuracy and avoid the glass 11 scratching the thickness detection device 4 when the glass 11 explodes. In a specific embodiment, the distance detection device 15 is a laser ranging sensor. The laser ranging sensor has high measurement accuracy, fast response speed, is not affected by the surface characteristics of the target (such as color, shape, etc.), and can work under different lighting conditions. The laser ranging sensor can quickly and accurately detect the approach of the glass 11.

[0043] As an implementation manner, a protective cover 17 is provided on the outer side of the thickness detection device 4 , and the protective cover 17 is used to protect the thickness detection device 4 and increase the service life of the thickness detection device 4 .

[0044] Furthermore, an alarm device 7 is provided above the electric control box 5, and the alarm device 7 is connected to the control device, and is used to sound an alarm when the distance detection device 15 detects that the glass 11 is broken (i.e., the glass 11 is close to the distance detection device 15). Specifically, the alarm device 7 includes a light emitting diode and a sounding device, such as a buzzer and a speaker. In other embodiments, when an abnormality occurs in the glass thickness detection device with multiple probes, the alarm device 7 sounds an alarm.

[0045] As an implementation method, Figure 3 and Figure 4 As shown, the thickness detection device 4 is a spectral confocal sensor, which refers to a sensor using spectral confocal technology. Specifically, the spectral confocal sensor includes a light source, a flexible optical fiber, a dispersive lens and a spectrometer. The optical fiber is connected to the light source, and the light source emits a beam of complex light (white) with a wide spectrum, which is spectrally dispersed through the dispersive lens to form monochromatic light of different wavelengths, and the focus of each monochromatic light of different wavelengths corresponds to a distance value. When the monochromatic light is irradiated to the surface of the glass 11, reflection will occur. Since the glass 11 is light-transmitting, the back of the glass 11 will also be reflected, and a focus will be generated on the front and back of the glass 11. Only the monochromatic light that meets the confocal condition can be sensed by the spectrometer through the small hole. Then the thickness of the glass 11 is calculated based on the distance value of the focus on the front of the glass 11 and the distance value of the focus on the back of the glass 11.

[0046] As an implementation mode, the control device can compare the data detected by the three thickness detection devices 4. When the data detected by different thickness detection devices 4 differ too much, the control alarm device 7 will sound an alarm. Furthermore, the control device has an automatic calibration function. Compared with a single thickness detection device 4, multiple thickness detection devices 4 can calibrate each other, thereby improving the detection accuracy. In other implementation modes, the data detected by the three thickness detection devices 4 are transmitted to an external central control system by wire or wireless means.

[0047] Furthermore, the control device also includes a wireless communication module, which is used to send the thickness value to an external terminal device that establishes a communication connection with the terminal device, such as a mobile phone and a computer.

[0048] As an embodiment, the electric control box 5 also includes an alarm data sending device, which is connected to the control device and is used to send alarm data to the user's mobile smart device (such as a mobile phone and a laptop computer) when the alarm device 7 sounds an alarm.

[0049] Furthermore, the display device 6 is connected to the control device and is used to display the data in the control device. Specifically, the display device 6 is located on the surface of the electric control box 5, which is convenient for the user to observe.

[0050] As an embodiment, after the glass 11 arrives on the glass conveying device 1, it moves on the glass conveying device 1 through the rotation of the roller 8. During the movement of the glass 11 on the glass conveying device 1, when passing through the distance detection device 15, if the distance detection device 15 detects that the glass 11 is approaching the thickness detection device 4 (the glass 11 is broken), the control device will control the second drive device 14 to move away from the glass 11 (i.e., move upward). If the glass 11 is not broken, the glass 11 continues to move. When the glass 11 moves below the multiple thickness detection devices 4, the multiple thickness detection devices 4 respectively detect the thickness of different areas of the glass 11.

[0051] The beneficial effect of the technical solution of the present invention is that a plurality of movable thickness detection devices are arranged above the glass conveying device, and the thickness of glass in different areas is detected in real time during the movement of the glass, thereby improving the efficiency of detecting the thickness of the glass and being able to more comprehensively detect the thickness of different areas of the glass.

[0052] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
