Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering furnaces, in particular to a self-balancing infrared temperature measuring probe device for a glass tempering furnace. Background Art

[0002] An infrared thermometer is a non-imaging monitoring instrument that can only monitor the average temperature at a measured point or within a small field of view. Its basic structure includes several main functional parts such as an infrared detector, an optical system, an information processing system, signal amplification, and result display. Its working process can be described as follows: First, the optical system collects the infrared radiation energy generated by the thermal-induced molecular vibration of the target object through the infrared detector, and the received radiation energy is converged by a lens through a reflecting beam splitter. After being processed by a filter, it is received by the infrared detector. The detector converts the received energy into an electrical signal, which is then amplified and processed by an amplifier and displayed by a display to show the temperature of the target object.

[0003] The factors affecting the temperature measurement of an infrared thermometer include emissivity, field of view, installation distance, spectral range, installation angle, vibration, the material and surface characteristics of the object to be measured, and environmental factors such as dust, water vapor, and smoke.

[0004] The patent with the authorization announcement number CN207600631U relates to a temperature measuring device for glass tempering. This device is arranged at the bottom of the tempering furnace and is provided with a column, a porcelain tube, a protective lens, a temperature measuring probe, a protective sleeve, a baffle, a small air box, etc., and is used to measure the lower surface temperature of ordinary glass and coated glass. This device uses a process of controlling the glass out-of-furnace temperature for the production of tempered glass, changing the previous tempering process that judged the heating time based on the experience of operators, and improving the qualification rate of tempered glass products and the stability of quality.

[0005] In the current prior art, when installing a temperature measurement system, first, a test hole is reserved in the gap of the ceramic roller path at the bottom of the furnace body. The infrared temperature measuring probe is installed on an installation bracket fixed to the foundation at the bottom of the furnace body, and the coaxiality between the probe and the test hole is adjusted. During temperature measurement, the probe detects the temperature of the lower surface of the glass through the test hole and transmits the temperature value to the control center in real time to obtain the real-time temperature value of the glass. However, the installation of the infrared temperature measuring probe is often carried out in a cold state. When in a hot state, the heating furnace will undergo slight uncontrollable deformation or displacement. At this time, the relative position between the temperature measurement hole on the furnace body and the infrared probe will change, affecting the perpendicularity between the infrared probe and the glass surface, and further affecting factors such as the temperature measurement path and temperature measurement angle of the infrared probe, resulting in measurement deviation or measurement error, seriously affecting the accuracy and stability of temperature measurement, and causing fluctuations in product quality.

[0032] Next, the present utility model will be specifically described through exemplary embodiments. However, it should be understood that, without further description, the elements, structures, and features in one embodiment can also be beneficially combined into other embodiments.

The words such as "a", "an", or "the" used in the specification and claims of the present utility model patent application do not express a limitation of quantity, but indicate that there is at least one; the "first", "second", and "third" used herein should not be regarded as a limitation on the order of components, but only for distinguishing different components; words such as "comprising" or "including" indicate that the elements or objects appearing before "comprising" or "including" cover the elements or objects listed after "comprising" or "including" and their equivalents, but do not exclude other elements or objects with the same functions.

[0034] In order to more clearly describe the specific structural composition of the self-balancing infrared temperature measurement probe device of a glass tempering furnace, the following embodiments will be described in conjunction with the attached Figures 1-4 description:

[0035] As Figure 1 、 Figure 3 shown, the glass tempering furnace 1 is provided with a ceramic roller table 101 that drives the glass 9 to move horizontally, and a reserved temperature measurement hole 102 corresponding to the gap of the ceramic roller table 101 vertically is also provided on the bottom surface of the glass tempering furnace 1;

[0036] Embodiment 1:

[0037] Referring to Figure 1 and Figure 4 , a self-balancing infrared temperature measurement probe device of a glass tempering furnace includes a stability base 2, and an infrared probe 3 is provided on the stability base 2; the bottom surface of the glass tempering furnace 1 and the stability base 2 are movably connected by at least three telescopic members 4 arranged circumferentially along the reserved temperature measurement hole 102, and the temperature measurement end of the infrared probe 3 can pass upward through the reserved temperature measurement hole 102 and be opposite to the gap of the ceramic roller table 101; the axis of the telescopic member 4 forms an angle α with the axis of the infrared probe 3, α < 90°, and both ends of the telescopic member 4 are movably connected to the bottom surface of the glass tempering furnace 1 and the stability base 2 respectively; the stability base 2 is provided with a gyroscope 5 for detecting its own three-dimensional posture, and cooperatively controls the telescopic amount of the telescopic member 4 according to the feedback of the three-dimensional posture to keep the infrared probe 3 always vertically upward; it also includes a processor for receiving the data of the gyroscope 5 and controlling the telescopic amount of the telescopic member 4.

[0038] The telescopic member 4 is axially arranged and forms a certain angle with the axis of the infrared probe 3. After multiple heating and cooling processes, the glass tempering furnace 1 will undergo slight uncontrollable deformation or displacement in the hot state, and then drive one end of the telescopic member 4 in a certain direction on the furnace body to move accordingly. At this time, the gyroscope 5 will sense the attitude change data of the telescopic member 4 and the entire stability base 2, and then the telescopic members 4 in other directions will adjust the extended length under the control of the controller to maintain the balance of the attitude, so as to ensure that the infrared probe 3 always maintains a vertically upward direction, improving the stability of the device.

[0039] When the included angle α is less than 90°, the stability base 2 is pulled by its own downward gravity and the upward component force of the telescopic member 4. Therefore, even if both ends of the telescopic member 4 are movably connected, the stability base 2 can remain stable and immovable;

[0040] To further maintain the stability of the stability base 2 without shaking, one end of the telescopic member 4 is hinged to the bottom surface of the glass tempering furnace 1 through a hinge member.

[0041] Embodiment 2:

[0042] Different from Embodiment 1:

[0043] Refer to Figure 3 , the included angle α > 90°, that is, the inclination direction of the telescopic member 4 is opposite to that of Embodiment 1. Since the stability base 2 is located above the telescopic member 4, when using the movably connected method at both ends in Embodiment 1, the end close to the stability base 2 may generate circumferential torsion relative to the telescopic member 4 during deformation. To ensure reliable stability, the lower end of the telescopic member 4 is movably connected to the bottom surface of the glass tempering furnace 1, and the upper end of the telescopic member 4 is hinged to the stability base 2.

[0044] In the above two embodiments:

[0045] Refer to Figure 2 , specifically, the hinge member or the hinged method specifically includes fixing a shaft seat 6 on the bottom surface of the glass tempering furnace 1, and a rotating shaft 7 rotatably connected to the shaft seat 6 is fixed at the upper end of the telescopic member 4.

[0046] The way of movable connection is that the lower end of the telescopic member 4 is connected to the stability base 2 through a spherical plain bearing 8, and the movable connection can ensure the degree of freedom of the stability base 2.

[0047] The stability base 2 is specifically a rotating body, and the infrared probe 3 is located on its rotation center line, so as to ensure that the mass distribution of the stability base 2 is uniform and no torsional tendency will occur.

[0048] Specifically, the telescopic member 4 is an electric push rod, a linear motor or other mechanisms that can control the telescopic movement.

[0049] Specifically, the infrared probe 3 includes a probe body and a probe protection box 301 disposed at the emission end of the probe body and capable of passing through the reserved temperature measurement hole 102.

[0050] Specifically, the processor is wirelessly or wiredly connected to the infrared probe 3, the telescopic member 4, and the gyroscope 5 respectively. The processor can be provided on the stability base 2 or placed in an external control box. The processor has three-dimensional attitude initial state data in a balanced state (with the infrared probe 3 vertically upward). The gyroscope 5 monitors the attitude of the infrared probe 3 in real time. When the furnace bottom of the glass tempering furnace 1 is affected by deformation, the real-time three-dimensional attitude data transmitted by the gyroscope 5 to the processor changes relative to the three-dimensional attitude initial state data. The processor timely controls the contraction of the telescopic member 4 to restore the stability base 2 and the infrared probe 3 to the three-dimensional attitude initial state.

[0051] The parts not detailed in the above embodiments are prior art.

[0052] It should be noted that although the present invention has been described through the above embodiments, the present invention can also have many other embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and deformations to the present invention, but these changes and deformations should all fall within the scope protected by the appended claims of the present invention and their equivalents.
