Description

Technical Field

[0001] The present invention belongs to the technical field of grinding equipment, and in particular relates to a processing equipment for ceramic-based heat insulation products and a processing method thereof. Background Art

[0002] Currently, heat insulation ceramic products (ceramic insulation boards) are usually composed of a ceramic substrate and a heat insulation material wrapping layer. After sintering, the ceramic substrate may have problems such as local protrusions, burrs, or excessive roughness on the surface due to process problems (such as uneven sintering temperature and coarse raw material particles). These surface defects will form air gaps between the heat insulation material and the substrate, affecting the fitting tightness, weakening the interfacial thermal resistance performance, and reducing the heat insulation effect. Moreover, sharp protrusions may pierce the heat insulation material (such as foam or fiber materials), causing damage to the wrapping layer. Therefore, before the ceramic substrate is compounded with the heat insulation material, the surface of the ceramic substrate needs to be polished to ensure the flatness of the ceramic substrate surface and improve the overall performance of the heat insulation ceramic product. For example, the patent with the authorization announcement number CN210024702U discloses a processing device for preparing heat insulation and anti-scalding ceramic products.

[0003] Currently, when the ceramic substrate is polished by a belt grinding machine, first, the human eye needs to observe the roughness of the ceramic substrate surface and judge the appropriate precision of the grinding belt for grinding treatment. Then, the staff holds the ceramic substrate and goes to the selected belt grinding machine for grinding. However, the grinding process of the ceramic substrate is relatively cumbersome, and the manual workload is large. At the same time, due to the differences in individual judgment criteria, the roughness evaluation error is significant, affecting the convenience and efficiency of the ceramic substrate grinding treatment. Moreover, during the process of holding the ceramic substrate for grinding, due to the friction of the grinding belt, the ceramic substrate is likely to fall off accidentally, resulting in accidents such as damage to the ceramic substrate and injury to the staff, thus affecting the safety of the grinding process of the heat insulation ceramic product. In addition, long-term repetitive manual operations are likely to cause fatigue damage to the operators, greatly increasing the labor intensity and making it difficult to meet the precision and efficiency requirements of industrial large-scale production.

[0004] Therefore, we propose a processing equipment for ceramic-based heat insulation products and a processing method thereof to solve the above problems. Summary of the Invention

A connecting hole matching the hollow strip is opened on the upper surface of the hollow platform. Rectangular air outlet holes are opened on the side wall of the hollow strip.

[0014] A processing method for a processing equipment for ceramic matrix heat insulation products, the processing method includes the following steps: Step S1: When the ceramic substrate needs to be polished during the processing of the heat insulation ceramic product, first, the robotic arm of the heat insulation ceramic product production line clamps the ceramic substrate between the two L-shaped clamping plates of the automatic push plate mechanism, and then the industrial control computer controls the automatic push plate mechanism to push the ceramic substrate to the roughness visual judgment mechanism. Step S2: After the roughness visual judgment mechanism judges the surface roughness of the ceramic substrate, the industrial control computer controls the grinding mechanism to work, and the grinding mechanism can automatically select a grinding belt with an accuracy adapted to the surface roughness of the ceramic substrate. Step S3: In step S2, the industrial control computer also controls the automatic push plate mechanism to convey the ceramic substrate to directly below the grinding mechanism. After the grinding belt of the grinding mechanism is selected, the industrial control computer then controls the electric push rod to push the grinding mechanism into contact with the surface of the ceramic substrate for grinding. Step S4: In step S3, after processing with any one of the full rough grinding belt, semi-rough grinding belt, fine grinding belt, and polishing belt, subsequent grinding processes are still required to ensure that the surface of the ceramic substrate gradually becomes smooth, providing a high-quality processing basis for the wrapping layer of the subsequent composite thermal insulation material. Step S5: In step S3, after the ceramic substrate is ground by the grinding mechanism, the industrial control computer then uses the automatic push plate mechanism to push the ceramic substrate to the edge of the hollow platform. At this time, the ceramic substrate loses the restraint of the two L-shaped clamping plates and is conveniently clamped and conveyed to the next process by the robotic arm. Step S6: In step S3, due to the limitation of the two L-shaped clamping plates of the automatic push plate mechanism, the ceramic substrate does not need to be held manually during grinding. Step S7: In step S3, the industrial control computer starts the negative pressure dust removal mechanism. The negative pressure dust removal mechanism sucks air through the first air pipe, the second air pipe, and the third air pipe. The hollow part carries the particulate dust generated by the grinding of the ceramic substrate into the dust collector. After passing through the filtration and purification of the dust collector, the air finally discharged from the dust collector is conveyed to the hollow strip, and the air in the hollow strip is ejected through the rectangular air holes. The air flow ejected from the rectangular air holes can be blown to the ceramic substrate just placed on the automatic push plate mechanism, and the particulate dust attached to the surface of the ceramic substrate is blown and cleaned.

[0015] Compared with the existing technology, the advantages of a ceramic-based thermal insulation product processing device and its processing method are as follows: With the provided roughness visual judgment mechanism and automatic push plate mechanism, when the ceramic substrate needs to be ground during the processing of the thermal insulation ceramic product, first, the robotic arm of the thermal insulation ceramic product production line clamps the ceramic substrate between the two L-shaped clamping plates of the automatic push plate mechanism. Then, the industrial control computer controls the automatic push plate mechanism to convey the ceramic substrate directly below the CCD vision camera. At this time, the industrial control computer controls the third motor to pause for a period of time for the roughness judgment of the ceramic substrate surface. During this period, the CCD vision camera takes a surface photo of the ceramic substrate and transmits the photo data to the industrial control computer. The pre-installed photo comparison program in the industrial control computer automatically compares the photo taken by the CCD vision camera and judges the surface roughness of the ceramic substrate. When the roughness judgment time of the ceramic substrate surface is completed, the industrial control computer then controls the automatic push plate mechanism to push the ceramic substrate to directly below the grinding mechanism for grinding. This mechanism enables the ceramic-based thermal insulation product processing device to have the function of accurately judging the roughness of the ceramic substrate, reducing the labor intensity of the staff, and improving the convenience and efficiency of the preparation and processing of thermal insulation ceramic products.

[0016] Through the provided grinding mechanism and electric push rod, when the ceramic substrate is pushed by the automatic push plate mechanism to the position directly below the grinding mechanism, during this process, due to the information fed back by the roughness visual judgment mechanism, the industrial control computer controls the grinding mechanism to select the full-rough grinding belt, semi-rough grinding belt, fine grinding belt, and polishing belt to be directly below for grinding the ceramic substrate at the initial stage. If the roughness visual judgment mechanism determines that the surface roughness of the ceramic substrate is relatively rough, the industrial control computer then controls the semi-rough grinding belt to directly grind the ceramic substrate without being processed by the full-rough grinding belt, and then sequentially performs fine grinding and polishing processes, and so on, thereby ensuring that the surface of the ceramic substrate gradually becomes smooth, providing a high-quality processing basis for the subsequent wrapping layer of the composite thermal insulation material. Moreover, during the grinding process, the ceramic substrate is limited by two L-shaped clamping plates and does not need to be held manually, so accidents such as the ceramic substrate slipping out of the hand will not occur. This mechanism enables the equipment to have the function of automatically and stably grinding the ceramic substrate, and the grinding process can automatically select the appropriate grinding belt for grinding according to the roughness of the ceramic substrate, without wasting time by grinding each ceramic substrate through the four grinding belts one by one, reducing the labor intensity of the staff, improving the safety of the equipment for grinding the ceramic substrate, and improving the convenience and efficiency of the preparation and processing of heat-insulating ceramic products.

[0017] Through the provided negative pressure dust removal mechanism, when the ceramic substrate of the heat-insulating ceramic product is being ground by the grinding mechanism, the industrial control computer also controls the vacuum cleaner to start. The vacuum cleaner sucks the air inside the square frame and the U-shaped cover through the first air pipe, the second air pipe, and the third air pipe respectively. The air in these two places can carry the particulate dust brushed out by the rotating grinding belt, avoiding the particulate dust from spreading and polluting the environment. The third air pipe sucks the particulate dust generated by grinding the ceramic substrate through the hollow platform and the horizontal through hole, further avoiding the dust from spreading. Then the vacuum cleaner filters the dust in the air, and finally the vacuum cleaner transports the air to the hollow strip through the fourth air pipe and sprays it out through the rectangular air outlet. The air flow sprayed out from the rectangular air outlet can clean the surface of the ceramic substrate just placed on the automatic push plate mechanism, avoiding the particulate dust from adhering to the ceramic substrate and interfering with the accuracy of the roughness judgment of the roughness visual judgment mechanism. This mechanism enables the equipment to have the functions of dust collection and cleaning of particulate dust on the ceramic substrate, not only improving the environmental protection performance of the equipment, but also improving the accuracy of the equipment's judgment of the surface roughness of the ceramic substrate, and thus improving the reliability of the equipment in use.

[0026] The electric push rod 3, the first motor 411, the second motor 412, the display 54, the third motor 65 and the vacuum cleaner 91 are all electrically connected to the output end of the industrial control computer 52 through wires. The CCD vision camera 53 and the contact sensor 8 are both electrically connected to the input end of the industrial control computer 52 through wires. The above electrical equipment and electrical connections are all prior arts and are well known to those skilled in the art, so they will not be elaborated here.

[0027] Now, the operation principle of the present invention is described as follows: When the ceramic substrate needs to be polished during the processing of the heat-insulating ceramic product, first, the robotic arm of the heat-insulating ceramic product production line clamps the ceramic substrate between the two L-shaped clamping plates 66 of the automatic push plate mechanism 6. The distance between the two L-shaped clamping plates 66 matches the size of the ceramic substrate. At the same time, the bottom of the ceramic substrate contacts the upper surface of the hollow platform 1. Then, the industrial control computer 52 controls the third motor 65 to start for a period of time (such as 3 seconds). The driving end of the third motor 65 drives the lead screw 62 to rotate clockwise. Then, the lead screw 62 drives the two L-shaped clamping plates 66 to move through the nut 63 and the T-shaped plate 64. The two L-shaped clamping plates 66 push the ceramic substrate to slide on the hollow platform 1 and slide to directly below the CCD vision camera 53. At this time, the industrial control computer 52 controls the third motor 65 to pause for a period of time (such as 2 seconds) for judging the surface roughness of the ceramic substrate. During this period, the CCD vision camera 53 takes a surface photo of the ceramic substrate and transmits the photo data to the industrial control computer 52. The pre-installed photo comparison program in the industrial control computer 52 automatically compares the photos taken by the CCD vision camera 53 and judges the surface roughness of the ceramic substrate. This kind of comparison is a prior art and will not be elaborated here. After that, the industrial control computer 52 controls the polishing mechanism 4 to select which polishing belt according to the judged surface roughness of the ceramic substrate, that is, which step of rough grinding, semi-rough grinding, fine grinding or polishing is used for the initial polishing of the ceramic substrate. When the judging time of the surface roughness of the ceramic substrate is over, the industrial control computer 52 controls the third motor 65 to start for a period of time (such as 5 seconds) to push the ceramic substrate to directly below the polishing mechanism 4 for polishing treatment. This mechanism enables the ceramic-based heat-insulating product processing equipment to have the function of accurately judging the roughness of the ceramic substrate, reduces the labor intensity of the staff, and can accurately select the matching polishing belt at the same time, saving time and effort, and improving the convenience and efficiency of the preparation and processing of heat-insulating ceramic products; When the ceramic substrate is pushed by the automatic pusher mechanism 6 to directly below the grinding mechanism 4, during this process, due to the information fed back by the roughness visual judgment mechanism 5, the industrial control computer 52 controls the second motor 412 to start. The second motor 412 drives multiple driving belt rollers 45 to rotate clockwise simultaneously through a sprocket 416 and a transmission chain 417, thereby driving the full rough grinding belt 46, semi-rough grinding belt 47, fine grinding belt 48, and polishing belt 49 to rotate clockwise. If the roughness visual judgment mechanism 5 determines that the surface roughness of the ceramic substrate belongs to a very rough level, the industrial control computer 52 controls the output end of the first motor 411 not to rotate, so that the full rough grinding belt 46 is at the lowest position. Then the industrial control computer 52 controls the moving end of the electric push rod 3 to move downward. The electric push rod 3 pushes the full rough grinding belt 46 of the grinding mechanism 4 to contact the surface of the ceramic substrate for grinding for 1 minute. After 1 minute, the industrial control computer 52 controls the moving end of the electric push rod 3 to retract. The electric push rod 3 drives the grinding mechanism 4 to retract, thus avoiding the restriction of the hollow platform 1 when the square frame 44 of the grinding mechanism 4 rotates. After that, the industrial control computer 52 controls the output end of the first motor 411 to rotate. The first motor 411 drives the square frame 44 to rotate 90 degrees through the driving gear 413, external gear ring 415, and extension ring 414, so that the semi-rough grinding belt 47 is directly below. In this way, the cycle continues, and the surface of the ceramic substrate is successively ground by the semi-rough grinding belt 47 for 1 minute, the fine grinding belt 48 for 1 minute, and the polishing belt 49 for 1 minute, thereby ensuring that the surface of the ceramic substrate gradually becomes smooth, providing a high-quality processing basis for the subsequent wrapping layer of the composite thermal insulation material. If the roughness visual judgment mechanism 5 determines that the surface roughness of the ceramic substrate is relatively rough, the industrial control computer 52 controls the semi-rough grinding belt 47 to directly grind the ceramic substrate for 1 minute without being ground by the full rough grinding belt 46, and then successively performs fine grinding and polishing treatments. And so on. If the roughness visual judgment mechanism 5 determines it to be slightly rough due to a small amount of burrs on the surface of the ceramic substrate, the industrial control computer 52 directly controls the polishing belt 49 to be at the lowest position. The ceramic substrate can directly form a neat plane through grinding by the polishing belt 49 for 1 minute without starting to grind successively from the full rough grinding belt 46, saving time and effort, thereby improving the convenience and speed of the grinding process of the ceramic substrate. Moreover, during the grinding process, the ceramic substrate is limited by two L-shaped clamping plates 66 and does not need to be held manually, so an accident of the ceramic substrate slipping out of the hand will not occur; After the grinding is completed, the industrial control computer 52 controls the third motor 65 to start for a period of time (such as 10 seconds) to convey the ceramic substrate. Finally, the L-shaped clamping plate 66 on the left side moves downward under the limitation of the horizontal through hole 68 and the guiding inclined surface, and compresses the return spring 67. At the same time, the top of the L-shaped clamping plate 66 is located on the inner wall of the hollow platform 1. Then the screw barrel 63 continues to move along the lead screw 62, and the other L-shaped clamping plate 66 continues to slide along the horizontal through hole 68, and pushes the ceramic substrate to the upper surface of the side end of the hollow platform 1. At this time, the ceramic substrate loses the restraint of the two L-shaped clamping plates 66 and is conveniently clamped and conveyed to the next process by the robotic arm; After that, the industrial control computer 52 controls the driving end of the third motor 65 to reverse for a period of time (such as 20 seconds), so that the screw barrel 63 carries the two L-shaped clamping plates 66 back to the initial position for receiving the ceramic substrate, that is, the L-shaped clamping plate 66 on the right touches the contact sensor 8, and the contact sensor 8 sends an electrical signal to the industrial control computer 52. After receiving the signal of the contact sensor 8, the industrial control computer 52 prepares for the next ceramic substrate grinding process. This mechanism enables the equipment to have the function of automatically and stably grinding the ceramic substrate, and the grinding process can automatically select the appropriate grinding belt for grinding according to the roughness of the ceramic substrate, without wasting time by grinding each ceramic substrate through four grinding belts one by one, and reducing the labor intensity of the staff, as well as improving the safety of the equipment for grinding the ceramic substrate, and ensuring the convenience and efficiency of the preparation and processing of the heat-insulating ceramic products; When the ceramic substrate of the heat-insulating ceramic product is being ground by the grinding mechanism 4, the industrial control computer 52 also controls the vacuum cleaner 91 to start. The vacuum cleaner 91 sucks air through the first air pipe 92, the second air pipe 93 and the third air pipe 94 respectively. When the first air pipe 92 sucks air, it sucks the air inside the square frame 44 through the connecting cylinder 42. The second air pipe 93 sucks the air inside the U-shaped cover 95. The air in these two places can carry the particulate dust spun out by the rotating brushes of the full-rough grinding belt 46, the semi-rough grinding belt 47, the fine grinding belt 48 and the polishing grinding belt 49, avoiding the particulate dust from spreading and polluting the environment. The third air pipe 94 sucks the air inside the hollow platform 1, and the hollow platform 1 sucks the particulate dust generated by the grinding of the ceramic substrate through the horizontal through hole 68, further avoiding the dust from spreading. Then the vacuum cleaner 91 filters the dust in the air. Finally, the vacuum cleaner 91 conveys the air to the hollow strip 97 through the fourth air pipe 96 and sprays it out through the rectangular air outlet 98. The air flow sprayed out from the rectangular air outlet 98 can be blown to the ceramic substrate just placed on the automatic push plate mechanism 6, and blows and cleans the particulate dust attached to the surface of the ceramic substrate, avoiding these particulate dust from interfering with the accuracy of the roughness visual judgment mechanism 5 for roughness judgment. In addition, the time used in all stages of the equipment can be specifically set by the industrial control computer 52. This mechanism enables the equipment to have the functions of dust collection and cleaning of particulate dust on the ceramic substrate, not only improving the environmental protection performance of the equipment, but also improving the accuracy of the equipment for judging the surface roughness of the ceramic substrate, and further improving the reliability of the equipment use.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

9. A processing method applied to the processing equipment for the ceramic matrix heat insulation product described in claim 8, characterized in that, The method includes the following steps: Step S1: When the ceramic substrate needs to be polished during the processing of the heat-insulating ceramic product, first, the robotic arm of the heat-insulating ceramic product production line clamps the ceramic substrate between the two L-shaped clamping plates (66) of the automatic push plate mechanism (6). Then, the industrial control computer (52) controls the automatic push plate mechanism (6) to push the ceramic substrate to the roughness visual judgment mechanism (5). Step S2. After the roughness visual judgment mechanism (5) judges the surface roughness of the ceramic substrate, the industrial control computer (52) controls the polishing mechanism (4) to work, and the polishing mechanism (4) can automatically select a polishing belt with an accuracy adapted to the surface roughness of the ceramic substrate; Step S3. In step S2, the industrial control computer (52) also controls the automatic push plate mechanism (6) to convey the ceramic substrate to directly below the polishing mechanism (4). After the polishing belt of the polishing mechanism (4) is selected, the industrial control computer (52) then controls the electric push rod (3) to push the polishing mechanism (4) into contact with the surface of the ceramic substrate for polishing; Step S4. In step S3, after processing with any one of the full rough grinding belt (46), semi-rough grinding belt (47), fine grinding belt (48) and polishing belt (49), subsequent polishing processes are still required to ensure that the surface of the ceramic substrate gradually becomes smooth, providing a high-quality processing basis for the subsequent wrapping layer of the composite thermal insulation material; Step S5. In step S3, after the ceramic substrate is polished by the polishing mechanism (4), the industrial control computer (52) then pushes the ceramic substrate to the edge of the hollow platform (1) through the automatic push plate mechanism (6). At this time, the ceramic substrate loses the restraint of the two L-shaped clamping plates (66) and is conveniently clamped and conveyed to the next process by the robotic arm; Step S6. In step S3, due to the limitation of the two L-shaped clamping plates (66) of the automatic push plate mechanism (6), the ceramic substrate does not need to be held manually during polishing; Step S7. In step S3, the industrial control computer (52) starts the negative pressure dust removal mechanism (9) to work. The negative pressure dust removal mechanism (9) sucks air through the first air pipe (92), the second air pipe (93) and the third air pipe (94). The hollow part carries the particulate dust generated by the polishing of the ceramic substrate into the dust collector (91). After being filtered and purified by the dust collector (91), the air discharged from the dust collector (91) is finally conveyed to the hollow strip (97). The air in the hollow strip (97) is then ejected through the rectangular air outlet (98). The air flow ejected from the rectangular air outlet (98) can be blown to the ceramic substrate just placed on the automatic push plate mechanism (6) to blow and clean the particulate dust attached to the surface of the ceramic substrate.
