Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plate size detection, and particularly relates to a detection device for ceramic-based heat insulation plate production. BACKGROUND

[0002] The ceramic-based heat insulation plate is widely used in high-temperature scenes, and the length, width, thickness and flatness of the ceramic-based heat insulation plate directly affect the sealing performance and heat insulation effect during assembly, and size deviation is easy to cause heat leakage at the joint gap, installation stress cracking and even equipment failure, so the size needs to be strictly detected to guarantee product quality and application safety.

[0003] At present, there are various methods for detecting the thickness of the plate. Although the traditional tape detection is simple to operate, it has obvious shortcomings of poor precision and low efficiency, and it is difficult to meet the high-precision production requirement. At present, high-precision detection methods such as laser are generally used. For example, a measuring device for composite heat insulation plate length detection disclosed in patent publication No. CN120232355A realizes the measurement of the length of the plate by emitting laser and calculating the time required for receiving the reflected laser. However, the length and width of the ceramic-based heat insulation plate must meet the standard during installation, so as to avoid affecting the installation quality and overall heat insulation effect due to the too large joint gap. However, the existing detection method needs to separately detect the width after detecting the length, and the two detection actions not only increase the operation steps, but also prolong the detection cycle, which significantly affects the overall detection efficiency.

[0046] As shown in Figure 1 , Figure 2 and Figure 7 , the four vertical parts of the cover 3 are fixedly inserted with the transverse electric push rods 16 corresponding to the positions of the supporting plates 92, and the movable ends of the transverse electric push rods 16 are connected with the positioning plates 17 through the pressure sensors, and the transverse electric push rods 16 are electrically connected with the electrical control cabinet 1, and the positioning plates 17 are moved by the transverse electric push rods 16, so that the ceramic-based heat insulation plate can be centrally positioned, and the position accuracy is ensured.

[0047] The operating principle of the present application is described as follows: the ceramic-based heat insulation plate to be detected is placed on the supporting plate 92, the electrical control cabinet 1 is started, the electrical control cabinet 1 controls the transverse electric push rods 16 on the left and right sides to work, the transverse electric push rods 16 push the positioning plates 17 to move towards the ceramic-based heat insulation plate, until the side walls of the ceramic-based heat insulation plate abut against each other, under the pushing action of the two positioning plates 17, the ceramic-based heat insulation plate is horizontally centered in the left and right directions, at this time, the pressure sensors at the movable ends of the two transverse electric push rods 16 detect that the pressure reaches a threshold value, and feed back an electric signal to the electrical control cabinet 1, and the electrical control cabinet 1 controls the transverse electric push rods 16 on the left and right sides to move back to the original position, then the electrical control cabinet 1 controls the transverse electric push rods 16 on the front and back sides to work, and the ceramic-based heat insulation plate can be centrally positioned in the front and back directions in the same way, and through the pushing action of the four transverse electric push rods 16, the ceramic-based heat insulation plate can be kept coaxial with the supporting plate 92.

[0048] After 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 undercover 3 to move downward and abut against the machine table 2, at this time the lifting electric push rod 42 stops working, and the pressing plate 63 will press the ceramic-based heat insulation plate against the supporting plate 92 (the area of the supporting plate 92 is smaller than that of the ceramic-based heat insulation plate, and corresponding specifications of the supporting plate 92 can be selected according to different specifications of the ceramic-based heat insulation plate), then the electrical control cabinet 1 controls the frame-shaped dot matrix laser panel 7 and the frame-shaped laser receiver 8 to work, the frame-shaped dot matrix laser panel 7 emits a laser beam perpendicular to the ceramic-based heat insulation plate, part of the laser beam is blocked by the ceramic-based heat insulation plate and cannot be projected onto the frame-shaped laser receiver 8, so the area receiving the laser through the frame-shaped laser receiver 8 can determine the length and width dimensions of the ceramic-based heat insulation plate, that is, the laser received by the frame-shaped laser receiver 8 forms a light spot array complementary to the outline of the ceramic-based heat insulation plate, through a pre-set coordinate calibration system, the light spot position of the receiving area is converted into coordinate data, the unblocked laser corresponds to the outside of the plate edge, and the blocked area corresponds to the coverage range of the plate, using the coordinate difference value of the edge light spot, combined with the interval parameter of the laser dot matrix, the length and width values of the plate can be calculated, the electrical control cabinet 1 will upload the length value to the computer, and issue a voice alarm when the length and width dimensions are unqualified;

[0049] After the length and width detection is qualified, the electrical control cabinet 1 will control the pressure electric push rod 133 to work regularly, the pressure electric push rod 133 will push each rack 131 down through the moving frame 134, 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 regular work of the pressure electric push rod 133 ends, the rotating plate 101 rotates 90°, changes 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 in the upward orthogonal projection range of the ceramic base heat insulation plate to work according to the length and width data measured in front (i.e. the laser head directly above the outside of the ceramic base heat insulation plate profile does not work), at this time, the emitted laser beam irradiates to each convex lens 102, and under the condensing effect of the convex lens 102, multiple laser beams in the same area are gathered and projected on the ceramic base heat insulation plate, the gathered laser beam will transfer energy to the ceramic base heat insulation plate, so that the surface of the ceramic base heat insulation plate is heated and warmed (the temperature varies based on the material of the ceramic base heat insulation plate and the laser beam energy 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 temperature probe 112 in each support plate 92 to work, after 1 minute, the temperature probe 112 converts the temperature into an electrical signal and feeds back to the electrical control cabinet 1, the electrical control cabinet 1 compares the electrical signal with the preset standard electrical signal (the preset standard electrical signal can be measured according to the qualified ceramic base heat insulation plate under the same conditions), judges whether the heat insulation performance of the ceramic base heat insulation plate is qualified, for example, when the thickness of the ceramic base heat insulation plate is too thin, the heat insulation performance of the ceramic base heat insulation plate becomes poor, resulting in that the temperature conducted to the temperature probe 112 exceeds the standard, or the poor heat insulation performance caused by uneven density, so after the length and width dimensions are measured, the laser can also be used to quickly detect whether the heat insulation performance of the ceramic base heat insulation plate is qualified;

[0050] After the detection is completed, the electrical control cabinet 1 controls the lifting electric push rod 42 to push the upper part of the dark cover 3 to reset, at this time, the ceramic-based heat insulation plate can be taken out, wherein, in order to improve the accuracy of temperature detection, after the ceramic-based heat insulation plate is placed on the support plate 92, before the electrical control cabinet 1 starts the lifting electric push rod 42, the electrical control cabinet 1 will first control the air pump 121 to start working, at this time, the gas delivered by the air pump 121 will enter the inside of the dark cover 3, and then enter the hollow compression plate 63 through the threaded sleeve 61 and the hollow adjusting stud 62, and then be sprayed out through the exhaust hole 14, under the action of the gas flow sprayed out, the dust and other impurities on the surface of the ceramic-based heat insulation plate will be blown away, so that the accuracy of the detection of the size and heat insulation performance of the ceramic-based heat insulation plate can be avoided as much as possible. After the air pump 121 works for 30 seconds, the electrical control cabinet 1 controls the lifting electric push rod 42 to work, and controls the electric control valve 18 in the ventilation hole to be electrified and opened, at this time, the gas flow output by the air pump 121 will flow into the lower part of the fixed plate 5 through the ventilation hole (since the compression plate 63 abuts against the ceramic-based heat insulation plate, the gas flow cannot flow from the exhaust hole 14), and then flows back to the suction end of the air pump 121 through the filter 15, at the same time, the electrical control cabinet 1 controls the electric heater 123 to work, the electric heater 123 heats at a temperature of 60℃, and the gas flow will be heated by the electric heater 123 when flowing through the inside of the heating cover 122, through the circulation of the gas flow in the dark cover 3, the temperature in the dark cover 3 can be kept at a stable temperature, so that the detection of the heat insulation performance of the ceramic-based heat insulation plate can be avoided as much as possible. At the same time, in continuous detection, through the external circulation of the air in the dark cover 3, the high-temperature heat generated during heating detection can be quickly dissipated, so as to avoid affecting the continuous detection efficiency.

[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
