Description

Technical Field

[0001] The present invention belongs to the technical field of plate size detection, and in particular relates to a detection device for producing ceramic-based thermal insulation boards. Background Art

[0002] Ceramic-based insulation boards are widely used in high-temperature scenarios. The dimensional accuracy of their length, width, thickness, flatness, etc. directly affects the assembly sealing and thermal insulation effect. Dimensional deviations can easily lead to heat leakage through splicing gaps, installation stress cracking, and even equipment failure. Therefore, strict dimensional inspection is required to ensure product quality and application safety.

[0003] Currently, there are various methods for measuring the thickness of plates. Although traditional tape measures are simple to operate, they have obvious disadvantages of poor accuracy and low efficiency, making it difficult to meet the needs of high-precision production. High-precision detection methods such as lasers are now commonly used. For example, patent announcement number CN120232355A discloses a measuring device for detecting the length of a composite insulation board. The device measures the length of the board by emitting a laser and calculating the time required to receive the reflected laser. However, when installing ceramic-based insulation boards, there are strict requirements for both length and width, and they must meet the standards at the same time to avoid affecting the installation quality and overall insulation effect due to excessive joints. However, the existing detection method requires a separate width detection after detecting the length. The two detection actions not only increase the operating steps, but also extend the detection cycle, significantly affecting the overall detection efficiency. Summary of the Invention

[0032] As shown in Figure 1 , Figure 2 , Figure 4 , and Figure 5 , the drive assembly 13 includes a rack 131 slidingly arranged in the inside of the light shield cover 103, the pin rod of the rotating plate 101 is fixedly sleeved with a gear 132 engaged with the rack 131, the top of the dark cover 3 is fixedly inserted with a pressure applying electric push rod 133 electrically connected with the electric control cabinet 1, and the movable end of the pressure applying electric push rod 133 is fixedly connected with a moving frame 134, the sidewall of each of the four vertical parts of the dark cover 3 is provided with a sliding opening 135 matched with the moving frame 134, and the end of the moving frame 134 away from the pressure applying electric push rod 133 is fixedly connected with the sidewall of each of the racks 131 through each of the sliding openings 135, so that the four rotating plates 101 can be driven to rotate 90° synchronously at one time As shown in Figure 1 , Figure 2 , Figure 3 , and Figure 7 , the inside of the pressing plate 63 is hollow, and a plurality of exhaust holes 14 are formed in the bottom of the pressing plate 63, the adjusting stud 62 is hollow, the inside of the pressing plate 63 is communicated with the adjusting stud 62 through the threaded sleeve 61, the top of the threaded sleeve 61 penetrates through the fixed plate 5, the gas outlet end of the return pipe 124 is arranged on the upper side of the fixed plate 5, the suction end of the gas pump 121 is provided with a detachable filter 15, and the air inlet end of the filter 15 is communicated with the inside of the dark cover 3, the inside of the ventilation hole is provided with an electric control valve 18, and through the electric control valve 18, after the pressing plate 63 abuts against the ceramic-based heat insulation plate, the airflow can also normally flow in the inside of the dark cover 3.

[0033] As Figure 1 、 Figure 2 and Figure 7 As shown, the four vertical side walls of the dark cover 3 are fixedly connected with horizontal electric push rods 16 corresponding to the position of the support plate 92, and the movable end of the horizontal electric push rod 16 is connected to the positioning plate 17 through a pressure sensor. The horizontal electric push rod 16 is electrically connected to the electrical control cabinet 1. The positioning plate 17 is pushed to move by the horizontal electric push rod 16, so that the ceramic-based insulation board can be centered to ensure the accuracy of the position.

[0034] The operating principle of the present invention is now explained as follows: the ceramic-based heat insulation board to be tested is placed on the support plate 92, and the electrical control cabinet 1 is started. The electrical control cabinet 1 will first control the horizontal electric push rods 16 in the left and right directions to work, and the horizontal electric push rods 16 will push the positioning plate 17 to move in the direction of the ceramic-based heat insulation board until it is against the side wall of the ceramic-based heat insulation board. Under the pushing action of the positioning plates 17 on both sides, the ceramic-based heat insulation board is horizontally centered in the left and right directions. At this time, the pressure sensors at the active ends of the two horizontal electric push rods 16 will detect that the pressure reaches the threshold value and feedback an electrical signal to the electrical control cabinet 1. The electrical control cabinet 1 will control the horizontal electric push rods 16 on the left and right sides to move back and reset. Then the electrical control cabinet 1 controls the horizontal electric push rods 16 on the front and rear sides to work. Similarly, the ceramic-based heat insulation board can be pushed to the front and rear centering position. Through the pushing action of the four horizontal electric push rods 16, the ceramic-based heat insulation board can remain coaxial with the support plate 92. After the positioning is completed, the electrical control cabinet 1 controls the lifting electric push rod 42 to work, and the lifting electric push rod 42 will drive the dark cover 3 to move down and against the machine table 2 through the support frame 41. At this time, the lifting electric push rod 42 stops working, and the clamping plate 63 will press the ceramic-based heat insulation board onto the support plate 92 (the area of ​​the support plate 92 is smaller than the ceramic-based heat insulation board, and the support plate 92 of the corresponding specifications can be selected according to the different specifications of the ceramic-based heat insulation board). Then the electrical control cabinet 1 controls the frame-shaped dot matrix laser panel 7 and the frame-shaped laser receiver 8 to work, and the frame-shaped dot matrix laser panel 7 emits a laser beam perpendicular to the ceramic-based heat insulation board. Part of the laser beam is blocked by the ceramic-based heat insulation board and cannot be projected to On the frame-shaped laser receiver 8, the length and width of the ceramic-based thermal insulation board can be determined by the area where the frame-shaped laser receiver 8 receives the laser. That is, the laser received by the frame-shaped laser receiver 8 forms a light spot array that is complementary to the outline of the ceramic-based thermal insulation board. The light spot position in the receiving area is converted into coordinate data through a preset coordinate calibration system. The unblocked laser corresponds to the outer edge of the plate, and the blocked area corresponds to the coverage range of the plate. The coordinate difference of the edge light spot, combined with the spacing parameters of the laser dot array, can be used to calculate the length and width values ​​of the plate. The electrical control cabinet 1 will upload the length and width values ​​to the computer and issue a voice alarm when the length and width dimensions are unqualified; After the length and width detection is qualified, the electrical control cabinet 1 will control the pressure electric push rod 133 to perform timed work. The pressure electric push rod 133 will push each rack 131 downward through the movable frame 134, and the rack 131 will drive the gear 132 to rotate. The gear 132 drives the rotating plate 101 to rotate through the pin rod. After the timed work of the pressure electric push rod 133 is completed, the rotating plate 101 rotates 90°, from vertical to horizontal, and is located below the frame-shaped dot matrix laser panel 7. At the same time, the electrical control cabinet 1 controls the laser head within the upward projection range of the ceramic-based thermal insulation board according to the length and width data measured previously (that is, the laser head directly above the outer side of the ceramic-based thermal insulation board outline does not work). At this time, the emitted laser beam is irradiated to each convex lens 102, and under the focusing effect of the convex lens 102, multiple laser beams in the same area are concentrated and projected onto the ceramic-based thermal insulation board, and the concentrated laser beam transfers energy to the ceramic The ceramic-based thermal insulation board is heated to a high temperature on the surface thereof (the temperature varies depending on the material of the ceramic-based thermal insulation board and the energy of the laser beam of the frame-shaped dot matrix laser panel 7, and can be measured by experiment). At the same time, the electrical control cabinet 1 controls the operation of the temperature probes 112 in each support plate 92. After 1 minute, the temperature probes 112 convert the temperature into an electrical signal and feed it back to the electrical control cabinet 1. The electrical control cabinet 1 compares the electrical signal with a preset standard electrical signal (the preset standard electrical signal can be measured under the same conditions based on a qualified ceramic-based thermal insulation board) to determine whether the thermal insulation performance of the ceramic-based thermal insulation board is qualified. For example, when the thickness of the ceramic-based thermal insulation board is too thin, the thermal insulation performance of the ceramic-based thermal insulation board deteriorates, thereby causing the temperature conducted to the temperature probe 112 to exceed the standard, or the thermal insulation performance deteriorates due to uneven density. Therefore, after measuring the length and width, a laser can be used to quickly detect whether the thermal insulation performance of the ceramic-based thermal insulation board is qualified. After the detection is completed, the electrical control cabinet 1 controls the lifting electric push rod 42 to push the dark cover 3 to move up and reset. At this time, the ceramic-based thermal insulation board can be taken out. In order to improve the accuracy of temperature detection, after the ceramic-based thermal insulation board is placed on the support plate 92, the electrical control cabinet 1 will first control the air pump 121 to start working before starting the lifting electric push rod 42. At this time, the gas delivered by the air pump 121 will enter the interior of the dark cover 3, and enter the hollow pressing plate 63 through the threaded sleeve 61 and the hollow adjusting stud 62, and be ejected through the exhaust hole 14. Under the action of the ejected air flow, dust and other impurities on the surface of the ceramic-based thermal insulation board will be blown away, thereby minimizing the influence of dust and other factors on the accuracy of the detection of the size and thermal insulation performance of the ceramic-based thermal insulation board. After the air pump 121 has been working for 30 seconds, the electrical control cabinet 1 controls the lifting electric push rod 42 to work, and The electric control valve 18 in the control ventilation hole is energized and opened. At this time, the air flow output by the air pump 121 will flow through the ventilation hole to the bottom of the fixed plate 5 (because the clamping plate 63 is against the ceramic-based thermal insulation board, the air flow cannot flow from the exhaust hole 14), and return to the suction end of the air pump 121 through the filter 15. At the same time, the electrical control cabinet 1 controls the operation of the electric heater 123. The heating temperature of the electric heater 123 is 60°C. When the air flow passes through the inside of the heating cover 122, it will be heated by the electric heater 123. The circulation of the air flow inside the dark cover 3 can keep the temperature inside the dark cover 3 stable, thereby minimizing the impact of temperature fluctuations on the detection of the thermal insulation performance of the ceramic-based thermal insulation board. At the same time, during continuous detection, by circulating the air in the dark cover 3 outside, the high-temperature heat during heating detection can be quickly dissipated to avoid affecting the efficiency of continuous detection.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
