Description

Technical Field

[0001] This utility model relates to the field of temperature detection equipment technology, and in particular to a temperature measuring device. Background Technology

[0002] In the OLED glass production process, a platinum channel is used to regulate the temperature of the molten glass flowing from the furnace, thereby eliminating defects and improving quality. The platinum channel is housed in a sealed, temperature- and humidity-controlled chamber, where the ambient temperature can reach 50°C or even higher, and the humidity is greater than 80%. To ensure the normal operation of the entire platinum channel system, it is necessary to periodically monitor the temperature of various parts of the platinum channel itself, as well as the system's electrical components (such as copper busbars and transformers), motors, and other components.

[0003] Typically, temperature monitoring in platinum channel systems involves workers using handheld infrared thermometers to enter a constant temperature and humidity chamber to measure the temperature of various components. This method, with frequent entry and exit of workers, leads to fluctuations in temperature and humidity, affecting glass quality. Furthermore, workers operating in such high-temperature and high-humidity environments are prone to heatstroke and other discomfort. Currently, other fields employ temperature measuring devices that automatically raise and lower the infrared thermometer based on the height of a set target area. However, due to the high temperature in the constant temperature and humidity chamber where the platinum channel is located, the mechanical components of the measuring device expand due to heat. Because of the varying degrees of expansion among these components, some movement occurs, and the cumulative error can cause a significant deviation in the actual height of the infrared thermometer. On one hand, the compact arrangement of electrical components such as the copper busbars being measured means that a height deviation in the infrared thermometer may result in the actual measured component differing from the target measured component. On the other hand, deviations in the position of the temperature measurement within the platinum channel itself can also affect the worker's control over the overall process, ultimately impacting glass quality.

[0004] Therefore, there is an urgent need for a temperature measuring device to solve the above-mentioned technical problems. Utility Model Content

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] This embodiment provides a temperature measuring device, which is particularly suitable for use in environments with high temperature, low temperature, and fluctuating temperature.

[0044] like Figure 1 and Figure 2As shown, the temperature measuring device includes a base mechanism 10, a fixed bracket 20, a movable bracket 30, a first drive mechanism 40, a detection mechanism 50, a rotating shaft 60, a second drive mechanism 70, and a control module (not shown in the figure). The detection mechanism 50, the first drive mechanism 40, and the second drive mechanism 70 are all electrically connected to the control module. The control module communicates with an external system and is used to control the actions of the first drive mechanism 40, the second drive mechanism 70, and the detection mechanism 50 based on pre-stored programs or manual input. Optionally, the control module includes a PLC module, and the external system can be a DCS system (distributed control system). A DCS system is a computerized control system used in a factory or process; it is existing technology and will not be described in detail here. The PLC module communicates with the DCS system. The base mechanism 10 is mounted on an external support surface, such as the ground in the operating environment. The fixed bracket 20 is mounted on the base mechanism 10; the movable bracket 30 is movably connected to the fixed bracket 20; the first drive mechanism 40 can drive the movable bracket 30 to move vertically relative to the fixed bracket 20. A rotating shaft 60 extends horizontally and rotates in conjunction with a movable support 30. A detection mechanism 50 is connected to the rotating shaft 60, and a second drive mechanism 70 drives the rotating shaft 60 and the detection mechanism 50 to rotate. The detection mechanism 50 includes an infrared temperature measurement component 51 and a height detection component 52. The infrared temperature measurement component 51 detects the temperature of an external object, and the height detection component 52 detects its height from the support surface, thus obtaining the current height of the infrared temperature measurement component 51. The height detection component 52 communicates with the control component, thereby achieving communication with the first drive mechanism 40. Specifically, after receiving the detection result from the height detection component 52, the control module compares it with the default height of the temperature detection component in the current system. If the difference is greater than or equal to a preset value, it indicates that the height position deviation of the infrared temperature measurement component 51 is too large. In this case, the control module causes the first drive mechanism 40 to drive the movable support 30 to move up and down, thereby compensating for the height deviation. If the difference is less than the preset value, it indicates that the height position deviation of the infrared temperature measurement component 51 is within a reasonable range, and the infrared temperature measurement component 51 can directly begin temperature detection. It is understood that the preset value is a value set manually based on the actual measurement accuracy requirements. In some embodiments, the preset value can be 1mm, 2mm, 3mm, 4mm, 5mm, etc., and is not limited here.

[0045] In this embodiment of the temperature measuring device, the first driving mechanism 40 drives the movable bracket 30 to move up and down, which can drive the infrared temperature measuring component 51 to different heights for temperature measurement. Based on this, the second driving component drives the rotating shaft 60 to rotate the infrared temperature measuring component 51 around a horizontal axis, thereby expanding the temperature measuring range in the height direction to meet usage requirements. By setting a height detection component 52 fixed to the position of the infrared temperature measuring component 51, the actual height of the infrared temperature measuring component 51 can be detected before temperature measurement. Communication with the first driving mechanism 40 enables height compensation of the infrared temperature measuring component 51, ensuring the accuracy of its height and thus ensuring that the actual temperature measurement location matches the target temperature measurement location, improving the reliability of the temperature measuring device. It is understood that after the height of the infrared temperature measuring component 51 is calibrated and compensated by the height detection component 52 and the first driving mechanism 40, if the height of the rotating shaft 60 is not adjusted subsequently, height correction compensation is not necessary for each subsequent temperature measurement.

[0046] When this temperature measuring device is used in the working space of the platinum channel, it eliminates the need for frequent manual entry and exit from the constant temperature and humidity space, which helps maintain the environmental parameters of the space and thus ensures the quality of the glass produced. In addition, the results detected by the temperature measuring device can be fed back to the DCS system in real time, so that the staff can adjust the process parameters in real time based on the temperature detection results.

[0047] In this embodiment, the infrared temperature measurement component 51 includes a conventional infrared thermometer, which measures the wavelength of electromagnetic waves radiated by the object being measured during operation and determines the temperature of the object by utilizing the principle of wavelength variation with temperature. In some embodiments, the infrared temperature measurement component 51 may also have a built-in temperature compensation module to eliminate or reduce the influence of ambient temperature on the infrared thermometer through real-time calibration. In some embodiments, the detection mechanism 50 also includes a housing 53, within which the infrared temperature measurement component 51 is housed. Optionally, the housing 53 is made of a ceramic matrix composite material with a temperature resistance greater than 200°C. An inert gas may be encapsulated within the housing 53 to protect the infrared temperature measurement component 51 from moisture. Optionally, the height detection component 52 may be a laser rangefinder sensor, which may be installed inside or outside the housing 53.

[0048] like Figure 1 As shown, the line connecting the infrared temperature measurement component 51 and the height detection component 52 is parallel to the rotating shaft 60. This arrangement ensures that the heights of the infrared temperature measurement component 51 and the height detection component 52 remain consistent during the rotation of the detection mechanism 50 and the rotating shaft 60. Therefore, it is not necessary to drive the detection mechanism 50 to its initial state (e.g., the detection mechanism 50 is in a horizontal state) before height calibration of the infrared temperature measurement component 51 can be achieved.

[0049] In some embodiments, the fixed bracket 20 includes a first support member mounted on the base mechanism 10. The movable bracket 30 is connected to the first support member. At least a portion of the first support member is covered with a first covering layer made of heat-insulating material. By covering at least a portion of the first support member with heat-insulating material, the overall thermal deformation of the fixed bracket 20 can be minimized, thereby reducing the height deviation of the infrared temperature measuring component 51, reducing the workload of height calibration of the infrared temperature measuring component 51, and improving the temperature measuring efficiency of the temperature measuring device. Optionally, the first support member can be made of carbon fiber, steel, etc., and the first covering layer can be an aerogel heat-insulating layer. It is understood that since the hardness of heat-insulating materials is usually low, in this embodiment, the first covering layer can cover the parts of the first support member that are not connected to the base mechanism 10, the movable bracket 30, etc., that is, ensuring that the connection parts of the fixed bracket 20 with other components are rigidly connected, ensuring the reliability of the connection.

[0050] In some embodiments, the movable support 30 includes a second support member and a second covering layer. The second support member is movably connected to the fixed support 20, and the rotating shaft 60 is rotatably engaged with the first support member. At least a portion of the second support member is covered with the second covering layer, which is made of heat-insulating material. By covering at least a portion of the second support member with heat-insulating material, the overall thermal deformation of the movable support 30 can be minimized, thereby minimizing the height deviation of the infrared temperature measuring component 51, reducing the workload of height calibration of the infrared temperature measuring component 51, and improving the temperature measuring efficiency of the temperature measuring device. Optionally, the second support member can be made of carbon fiber, steel, etc., and the second covering layer can be an aerogel heat insulation layer. It is understood that since the hardness of heat insulation materials is usually low, in this embodiment, the second covering layer can cover the parts of the second support member that are not connected to the fixed support 20, rotating shaft 60, etc., that is, ensuring that the connection parts of the movable support 30 with other components are rigidly connected, ensuring the reliability of the connection.

[0051] like Figure 1 As shown, the base mechanism 10 includes a first base 11, a second base 12, and a rotation drive assembly 13. The first base 11 is supported on an external support surface, and the second base 12 rotates around a vertical axis with the first base 11. The fixed bracket 20 is connected to the second base 12. The rotation drive assembly 13 drives the second base 12 to rotate relative to the first base 11. Therefore, when the temperature measuring device is placed in a certain position in the usage environment, by driving the second base 12 to rotate, the infrared temperature measuring assembly 51 can detect the temperature of components arranged in various positions around the temperature measuring device without the need for manual adjustment of the temperature measuring device's position, further improving the convenience of temperature detection.

[0052] Specifically, a groove is provided on the first base 11, and a second base 12 is disposed within the groove. A driven gear 14 is disposed on the outer periphery of the second base 12, forming an annular gap 15 between the driven gear 14 and the sidewall of the groove. The rotary drive assembly 13 includes a third motor 131 and a drive gear 132. The third motor 131 is mounted on the first base 11, and the drive gear 132 is connected to the output end of the third motor 131. The drive gear 132 is disposed within the annular gap 15 and meshes with the driven gear 14. Therefore, when the third motor 131 drives the drive gear 132 to rotate, the driven gear 14 can drive the second base 12 and the detection mechanism 50 connected to the second base 12 to rotate. In this embodiment, the groove is formed on the upper surface of the first base 11, and the lower end of the second base 12 is rotatably engaged with the first base 11 through a bearing. The third motor 131 can be a high-temperature resistant stepper motor, and the drive gear 132 and the driven gear 14 are graphite-lubricated gears, thereby avoiding the problem of jamming during the rotation of the second base 12. It is understood that in other embodiments, a reducer or other components may be provided between the third motor 131 and the drive gear 132, which is not limited here.

[0053] In some embodiments (not shown), the base mechanism 10 is a movable base. This allows the temperature measuring device to move flexibly to various positions, thereby enabling more flexible detection of the temperature at the desired location. It is understood that, without departing from the inventive concept of this application, the base mechanism 10 can be any existing movable base.

[0054] like Figure 1 and Figure 2 As shown, the fixed bracket 20 includes a connecting component 21 and two first uprights 22. The connecting component 21 is connected to the base mechanism 10. Both first uprights 22 are connected to the connecting component 21 and are arranged opposite to each other. Each first upright 22 has a slide rail 221, with the openings of the two slide rails 221 facing each other. The movable bracket 30 includes a connecting rod 31 and two second uprights 32. Both second uprights 32 are connected to the connecting rod 31. Each second upright 32 is correspondingly positioned within a slide rail 221 and can move along the corresponding slide rail 221. The two ends of the rotating shaft 60 are respectively rotatably engaged with the two second uprights 32. This arrangement forms a U-shaped structure with the opening facing upwards, facilitating stress release. The movable bracket 30 is completely enclosed within the fixed bracket 20, ensuring a tight fit between the two and minimizing positional deviations due to thermal expansion, thus improving the convenience of height calibration for the infrared temperature measuring component 51. Figure 1As shown, the connecting component 21 forms a rectangular frame structure, which ensures the structural strength of the entire fixed bracket 20 without causing the overall weight of the temperature measuring device to be excessive. In other embodiments, the specific shape of the connecting component 21 is not limited. At least one of the two first uprights 22 is provided with a clearance hole 222. The clearance hole 222 is located at the bottom of the slide 221 and passes through the first upright 22. The clearance hole 222 is used to avoid the connection between the first drive mechanism 40 and the movable bracket 30, and the connection between the second drive mechanism 70 and the rotating shaft 60 (see the description below for details).

[0055] like Figure 1 and Figure 2 As shown, the first drive mechanism 40 includes a first motor 41, a lead screw 42, and a nut 43. The first motor 41 is mounted on a fixed bracket 20, the lead screw 42 extends vertically and can rotate relative to the fixed bracket 20, the nut 43 is threaded into the lead screw 42, and the movable bracket 30 is fixedly connected to the nut 43. Therefore, when the first motor 41 drives the lead screw 42 to rotate, the nut 43 can drive the movable bracket 30 to move up and down vertically. Furthermore, the transmission method of the lead screw 42 and nut 43 provides high motion accuracy, which can meet the height compensation requirements of the infrared temperature measurement component 51. In this embodiment, the first motor 41 can be a high-temperature resistant stepper motor and is mounted on a first upright 22. The two ends of the lead screw 42 are connected to the first upright 22 through bearing seats 23, thereby achieving rotational engagement between the lead screw 42 and the fixed bracket 20. The movable bracket 30 also includes a first connecting part 33. One end of the first connecting part 33 is connected to a second upright 32, and the other end extends out of the fixed bracket 20 after passing through the clearance hole 222. A nut 43 is installed on the first connecting part 33.

[0056] The temperature measuring device also includes a guiding mechanism, which comprises a fixed part and a movable part. The fixed part is connected to the fixed bracket 20 and extends vertically, while the movable part is connected to the movable bracket 30 and slides or rolls with the fixed part. By providing the guiding mechanism, the movement accuracy of the movable bracket 30 can be ensured, thereby ensuring the positional accuracy of the infrared temperature measuring component 51. Optionally, in some embodiments, the fixed part is a groove on the inner wall of the slide rail 221 of the first upright 22, and the movable part is a protrusion or roller connected to the second upright 32, which can slide along the groove. In some embodiments, the fixed part can also be a linear guide rail connected to the first upright 22, and the movable part is a slider connected to the second upright 32, with the slider slidingly engaging with the linear guide rail.

[0057] like Figure 1 and Figure 2As shown, the second drive mechanism 70 includes a second motor, which is connected to the movable bracket 30 and its output end is connected to the rotating shaft 60 for transmission, thereby driving the rotating shaft 60 to rotate. In this embodiment, the movable bracket 30 also includes a second connecting part 34, one end of which is connected to the second upright 32, and the other end passes through the avoidance hole 222 and extends out of the fixed bracket 20. The second motor is connected to the second connecting part 34. This arrangement can avoid interference between the second motor and the detection mechanism 50. In some embodiments, the second motor can be a high-temperature resistant stepper motor, which can be connected to the rotating shaft 60 through a reducer (not shown in the figure). In some embodiments, the second motor can also be a direct-drive motor, whose output end is directly connected to the rotating shaft 60.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, based on the concept of this utility model, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
