Description

Technical Field

[0001] The invention relates to the technical field of ceramic plate detection devices, and in particular to a thermal shock resistance detection line for large ceramic plates. Background Art

[0002] As an important building material, ceramic slabs are widely used in indoor and outdoor walls, floors and other places. The quality of their thermal shock resistance directly affects the quality and service life of the decoration project. If the ceramic slabs are easily damaged or cracked under the action of thermal shock, the quality and safety of the decoration project will be affected. Therefore, thermal shock resistance is one of the important indicators to measure the quality of ceramic slabs. Testing the thermal shock resistance of ceramic slabs can help the production side understand the thermal shock performance of ceramic slabs, and then optimize the production process and formula to improve the thermal shock resistance and durability of the product.

[0003] Existing thermal shock resistance testing equipment can usually only test small-sized samples. Since the specifications of ceramic panels are large, common specifications are usually 900×1800mm, 2400×1200mm, 3200×1600mm and 3600×1600mm. For super-large ceramic panels, it is usually necessary to cut the sample into multiple samples for testing, and multiple samples cut from the same ceramic panel need to be tested. Due to the need for cutting operations and repeated testing of multiple cut samples, the test efficiency is greatly reduced. Cutting into small pieces may increase the deviation between samples. Ceramic materials in different positions may have different microstructures and properties. When cutting into small pieces, boundary effects may also be introduced, affecting the accuracy of the test results. ‌‌ Summary of the invention

DETAILED DESCRIPTION

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0051] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0052] like Figure 1As shown, a thermal shock resistance test line for large ceramic panels is used for thermal shock resistance test of large ceramic panels, comprising a first conveying line 1, a second conveying line 2, a sample loading mechanism 3, an ink coating and cleaning mechanism 4, an observation mechanism 5, a sample unloading mechanism 6, a first immersion mechanism 7, a heating mechanism 8, a second immersion mechanism 9, a first translation mechanism 10 and a second translation mechanism 11;

[0053] The first conveyor line 1 and the second conveyor line 2 are arranged side by side, the conveying direction of the first conveyor line 1 is opposite to the conveying direction of the second conveyor line 2, the first conveyor line 1 and the second conveyor line 2 are respectively used to convey the sample 12, and the sample 12 is a large ceramic plate;

[0054] The loading mechanism 3, the ink-coating and cleaning mechanism 4, the observation mechanism 5 and the unloading mechanism 6 are sequentially arranged along the conveying direction of the first conveying line 1. The loading mechanism 3 is used to load the sample 12 onto the first conveying line 1. The ink-coating and cleaning mechanism 4 is used to ink and clean the sample 12. The observation mechanism 5 is used to take a photo of the sample 12 after ink coating. The unloading mechanism 6 is used to unload and recycle the sample 12 from the first conveying line 1.

[0055] The first immersion mechanism 7, the heating mechanism 8 and the second immersion mechanism 9 are sequentially arranged along the conveying direction of the second conveying line 2. The first immersion mechanism 7 and the second immersion mechanism 9 are respectively used to immerse the sample 12 in cold water, and the heating mechanism 8 is used to heat the sample 12.

[0056] The first translation mechanism 10 is arranged between the output end of the first conveyor line 1 and the input end of the second conveyor line 2, and the first translation mechanism 10 is used to translate the template 12 of the first conveyor line 1 to the second conveyor line 2; the second translation mechanism 11 is arranged between the output end of the second conveyor line 2 and the input end of the first conveyor line 1, and the second translation mechanism 11 is used to translate the template 12 of the second conveyor line 2 to the first conveyor line 1.

[0057] The working process of the thermal shock resistance test line for large ceramic panels of the present invention is as follows:

[0058] The loading mechanism 3 loads the sample 12 onto the first conveying line 1, and the sample 12 is inked and cleaned by the inking and cleaning mechanism 4. If there are cracks on the surface of the sample 12, after inking, the ink penetrates into the cracks, and obvious color marks are formed inside the cracks, thereby visually enhancing the visibility of the cracks. After cleaning and removing the excess dye, the location of the stained cracks can be more easily identified. The sample 12 after inking is photographed by the observation mechanism 5, and the surface of the sample 12 is manually observed from the photographed photos to see whether there are cracks. If there are cracks, the sample 12 already has cracks before the thermal shock test. When passing through the unloading mechanism 6, the sample is unloaded and recovered by the unloading mechanism 6. If there are no cracks on the surface of the sample 12 before the test, the sample 12 is translated from the first conveying line 1 to the second conveying line 2 by the first translation mechanism 10, and the sample 12 passes through the first immersion mechanism 7, the heating mechanism 8 and the second immersion mechanism 9 for hot and cold tests. The hot and cold tests can be selected in the following three ways:

[0059] 1. Cold-hot test: the sample 12 is immersed in cold water by the first immersion mechanism 7 and heated by the heating mechanism 8, but not immersed in cold water by the second immersion mechanism 9;

[0060] 2. Hot-cold test: the sample 12 is heated by the heating mechanism 8 and immersed in cold water by the second immersion mechanism 9, but not immersed in cold water by the first immersion mechanism 7;

[0061] 3. Cold-hot-cold test: the sample 12 is immersed in cold water by the first immersion mechanism 7, heated by the heating mechanism 8, and immersed in cold water by the second immersion mechanism 9;

[0062] The hot and cold test methods can be selected according to the test needs. Among them, the cold-hot-cold cycle method is the most stringent, simulating a more complex temperature change environment, and putting forward higher requirements on the thermal shock resistance of sample 12. It helps to reveal the potential defects and weaknesses of ceramic materials in a complex temperature change environment, and facilitates the subsequent improvement and optimization research on large ceramic panels.

[0063] After completing the hot and cold tests, the sample 12 is translated from the second conveyor line 2 back to the input end of the first conveyor line 1 by the second translation mechanism 11. After being inked and cleaned by the inking and cleaning mechanism 4, the observation mechanism 5 takes a photo of the inked sample 12, and observes whether there are cracks from the photograph. The test cycle is repeated multiple times, and when sampling is required, the sample 12 is unloaded and recovered by the unloading mechanism 6.

[0064] The ceramic large plate thermal shock test line can realize thermal shock cycle test of ceramic large plates. The size of the tested sample is 900×1800mm~3600mm×1800mm. The thermal shock test is performed on the entire ceramic large plate with high test accuracy, avoiding the situation where cutting into small pieces for testing reduces the test efficiency and affects the accuracy of the test results. Moreover, testing the entire ceramic large plate can more realistically simulate the working state of the ceramic large plate in actual applications. In actual applications, the ceramic large plate often appears in the form of a whole piece. The overall test can more accurately evaluate its performance under temperature changes, avoid the introduction of boundary effects when cutting into small pieces of samples, make the test results more accurate and reliable, and reduce sample deviation.

[0065] In addition, on the same ceramic plate thermal shock test line, multiple ceramic plates can be tested at the same time, which effectively improves the test efficiency and can realize thermal shock cycle tests of three different test modes: "cold-hot", "hot-cold" and "cold-hot-cold", which can be selected according to actual test requirements. Before the hot and cold tests, the inking cleaning mechanism 4 and the observation mechanism 5 can also be used to test the sample plates 12 that have been screened without cracks to improve the test accuracy.

[0066] like Figures 2 to 4 As shown, it is further explained that the first immersion mechanism 7 and the second immersion mechanism 9 have the same structure;

[0067] The first immersion mechanism 7 includes an immersion tank 71, a movable gantry 72, a lifting adsorption assembly 73 and a lifting bearing assembly 74, wherein the immersion tank 71 is arranged at one side of the second conveying line 2, the movable gantry 72 is erected above the second conveying line 2 and the immersion tank 71, and the movable gantry 72 is provided with a first guide rail 721, and the first guide rail 721 is arranged along the width direction of the second conveying line 2;

[0068] The lifting adsorption assembly 73 includes a first moving frame 731, a first driving device 732 and a lifting adsorption plate 733. The first moving frame 731 is connected to the transmission end of the first guide rail 721, and the first moving frame 731 moves along the first guide rail 721; the first driving device 732 is fixedly installed on the first moving frame 731, and the driving end of the first driving device 732 is connected to the lifting adsorption plate 733. The first driving device 732 drives the lifting adsorption plate 733 to move up and down. The plate array of the lifting adsorption plate 733 is provided with a plurality of vacuum suction cups 7331, and the adsorption end of the vacuum suction cup 7331 is arranged toward the immersion tank 71;

[0069] The lifting and lowering bearing assembly 74 includes a second driving device 741 and a bearing plate 742. The second driving device 741 is fixedly disposed in the immersion tank 71. The driving end of the second driving device 741 is connected to the bearing plate 742. The second driving device 741 drives the bearing plate 742 to rise and fall in the immersion tank 71.

[0070] By setting the mobile gantry 72, the first mobile frame 731 moves along the first guide rail 721. When the sample 12 on the second conveyor line 2 needs to be immersed in cold water, the first mobile frame 731 moves along the first guide rail 721 to the top of the second conveyor line 2, and the first driving device 732 drives the lifting adsorption plate 733 to descend and adsorb the sample 12. Then the first driving device 732 drives the lifting adsorption plate 733 to rise, and the first mobile frame 731 moves along the first guide rail 721 to the top of the immersion tank 71, and the second driving device 741 drives the supporting plate 742 to rise to a position above the water surface. The first driving device 732 drives the lifting adsorption plate 733 to descend and place the sample 12 on the supporting plate 742, and the vacuum suction cup 7331 releases the vacuum adsorption from the sample 12. At this time, the second driving device 741 drives the supporting plate 742 to descend below the water surface, so that the sample 12 is immersed in the immersion tank 71 for cold water immersion. When the soaking is completed, the second driving device 741 drives the supporting plate 742 to rise to a position above the water surface, so that the vacuum suction cup 7331 can adsorb the sample. After the vacuum suction cup 7331 adsorbs the sample 12, the first moving frame 731 moves along the first guide rail 721 to the top of the second conveyor line 2, and drives the lifting adsorption plate 733 to descend through the first driving device 732, so as to place the sample 12 back on the second conveyor line 2.

[0071] Due to the large area of ​​the ceramic plate, when the ceramic plate is immersed in water, if the vacuum suction cup 7331 is used alone to adsorb and lift the sample 12 from the upper end surface, it is necessary to overcome a very large resistance to lift the sample 12. The stability during lifting is poor, and the sample 12 is prone to shake under the action of resistance. If the sample 12 collides with the immersion tank 71 when shaking, it is easy to affect the accuracy of the thermal shock test of the sample 12. By setting the lifting bearing assembly 74, the bearing plate 742 supports the sample 12. When the sample 12 is immersed, the second driving device 741 provides a driving force from the bottom of the bearing plate 742 to drive the bearing plate 742 to rise slowly. At this time, since the sample 12 is supported by the bearing plate 742, the stability of the rising process is high and it is not easy to shake, thereby ensuring the accuracy of the detection.

[0072] In addition, when the lifting adsorption plate 733 descends and places the sample 12 on the supporting plate 742, the vacuum suction cup 7331 and the sample 12 are released from vacuum adsorption. Although the vacuum suction cup 7331 and the sample 12 are released from vacuum adsorption, when the second driving device 741 drives the supporting plate 742 to descend below the water surface, the first driving device 732 can also drive the lifting adsorption plate 733 to synchronously follow the supporting plate 742 to descend, so that the vacuum suction cup 7331 is lightly attached to the surface of the sample 12. When the sample 12 descends in the water, it can be maintained between the vacuum suction cup 7331 and the supporting plate 742, so that the sample 12 has high stability when descending in the water. It should be noted that although the vacuum suction cup 7331 is lightly attached to the surface of the sample 12 and follows the sample 12 into the water, it will not affect the use of the vacuum suction cup 7331. A vacuum droplet separator (such as the AMJ series vacuum droplet separator produced by Japan's SMC company) can be installed in the vacuum pipeline to remove water droplets in the air and prevent damage to the vacuum pump or vacuum generator.

[0073] During the hot and cold test, when transferring from high temperature to low temperature, it is necessary to achieve the effect of rapid cooling and heating. The present invention can quickly complete the process of moving the sample 12 from the heating mechanism 8 to the immersion tank 71 by setting the second conveying line 2, the mobile gantry 72, the first mobile frame 731 and the first driving device 732, thereby realizing the rapid transportation of large-sized samples 12, thereby achieving the effect of rapid cooling and heating, and further improving the detection accuracy.

[0074] Specifically, the mobile gantry 72 can adopt a dual-axis motor whose two output ends are respectively connected to the rotating shaft, and the rotating shaft is connected to the screw through a bevel gear. The screw is arranged along the direction of the first guide rail 721, and a slider is arranged on the screw. The slider slides along the first guide rail 721 and is connected to the first mobile frame 731, driving the first mobile frame 731 to move.

[0075] Specifically, the first driving device 732 may be an electric cylinder, and the second driving device 741 may be a waterproof electric cylinder.

[0076] Further explanation: a guide column 734 is connected between the lifting adsorption plate 733 and the first movable frame 731, one end of the guide column 734 is fixedly connected to the lifting adsorption plate 733, and the other end of the guide column 734 is slidably connected to the first movable frame 731. The guide column 734 is arranged in the up and down directions. By setting the guide column 734, the lifting and lowering process of the lifting adsorption plate 733 can be guided.

[0077] To further explain, an opening 711 is provided at the top of the immersion tank 71 , and the area of ​​the lifting adsorption plate 733 is adapted to the size of the opening 711 of the immersion tank 71 .

[0078] Since the sample 12 is a large ceramic plate with a large area, the size of the immersion tank 71 needs to adapt to the size of the sample 12, so that the opening of the immersion tank 71 is also larger. The larger opening 711 promotes the convection movement of air and accelerates the loss of cold, making the insulation effect of the immersion tank 71 poor and easy to lose temperature, affecting the effect of the cold and hot tests. By setting the area size of the lifting adsorption plate 733 to match the size of the opening 711 of the immersion tank 71, when the lifting adsorption plate 733 does not need to perform the adsorption action, the first driving device 732 can drive the lifting adsorption plate 733 to descend to the position of covering the opening 711 of the immersion tank 71. At this time, the lifting adsorption plate 733 can help the immersion tank 71 to play a certain insulation role, avoiding the cold water in the immersion tank 71 from losing temperature too quickly and affecting the cold water immersion effect. It should be noted that when the lifting adsorption plate 733 descends to the position covering the opening 711 of the immersion tank 71 , the lifting adsorption plate 733 does not contact the water in the immersion tank 71 and does not affect the vacuum suction cup 7331 on the lifting adsorption plate 733 .

[0079] Specifically, the first immersion mechanism 7 further includes a refrigeration device 75, which is connected to the immersion tank 71 and is used to cool the water in the immersion tank 71 to 10°C to 15°C.

[0080] To further explain, the supporting plate 742 is provided with a plurality of water passage grooves 7421 penetrating along the plate surface, and the plurality of water passage grooves 7421 are arranged in an array on the supporting plate 742 .

[0081] Since the sample 12 is a large ceramic plate, the area of ​​the large ceramic plate is relatively large, and therefore the area of ​​the supporting plate 742 is also relatively large. When the supporting plate 742 rises, it is easy to disturb the water body, so that the water in the immersion tank 71 is easy to overflow during the turbulence of the water flow. By setting a plurality of the water flow grooves 7421 on the surface of the supporting plate 742, and the plurality of the water flow grooves 7421 are arranged in an array on the supporting plate 742, the water flow grooves 7421 can make the water flow pass more smoothly, reduce the obstruction and accumulation of the water flow on the surface of the supporting plate 742, and further reduce the water flow turbulence generated during the rising process of the supporting plate 742, and avoid the water in the immersion tank 71 from overflowing.

[0082] like Figure 5 and Figure 6As shown, it is further explained that the ink cleaning mechanism 4 includes a frame 41, a longitudinal moving component 42, a transverse moving component 43, a nozzle 44 and a water receiving tank 45;

[0083] The frame 41 is erected above the first conveyor line 1, the water receiving trough 45 is arranged below the first conveyor line 1, the longitudinal moving assembly 42 is arranged on the frame 41, the transverse moving assembly 43 is arranged on the longitudinal moving assembly 42, the nozzle 44 is installed on the transverse moving assembly 43, the longitudinal moving assembly 42 drives the transverse moving assembly 43 and the nozzle 44 to move along the length direction of the first conveyor line 1, and the transverse moving assembly 43 drives the nozzle 44 to move along the width direction of the first conveyor line 1;

[0084] The nozzle 44 is used to spray ink or cleaning water onto the sample 12 on the first conveying line 1.

[0085] By setting the longitudinal moving assembly 42 and the transverse moving assembly 43, when the sample 12 moves to the position of the ink washing mechanism 4 on the first conveying line 1, the first conveying line 1 stops driving, and the longitudinal moving assembly 42 drives the transverse moving assembly 43 and the nozzle 44 to move along the length direction of the first conveying line 1 to spray ink in the length direction of the sample 12, and at the same time, the transverse moving assembly 43 drives the nozzle 44 to move along the width direction of the first conveying line 1 to spray ink in the width direction of the sample 12. After the ink spraying is completed, the longitudinal moving assembly 42 and the transverse moving assembly 43 drive the nozzle 44 to move, and the nozzle 44 sprays washing water on the surface of the sample 12 to wash and remove the ink. The water receiving tank 45 can receive the ink and washing water sprayed to the sample 12.

[0086] Specifically, the longitudinal moving assembly 42 includes a third driving device 421, a first transmission belt 422, a first gear 423, a second gear, a third gear, a second transmission belt 424, a rotating shaft 425, a fourth gear 426, and a second guide rail 427;

[0087] The lateral moving assembly 43 includes a second moving frame 431 and a lateral driving module;

[0088] The third driving device 421 is fixedly arranged on the frame 41, the rotating shaft 425 is rotatably arranged on the frame 41, the output end of the third driving device 421 is connected to the first gear 423, the second gear and the third gear are respectively fixedly connected to the rotating shaft 425, the fourth gear 426 is rotatably arranged on an end of the frame 41 away from the third driving device 421, one end of the first transmission belt 422 is wound around the first gear 423, the other end of the first transmission belt 422 is wound around the second gear, one end of the second transmission belt 424 is wound around the third gear, the other end of the second transmission belt 424 is wound around the fourth gear 426, the second transmission belt 424 is provided with a connecting block, and the connecting block is connected to the second movable frame 431;

[0089] The second guide rail 427 is disposed on the frame 41 along the length direction of the frame 41 , and the second movable frame 431 is slidably connected to the second guide rail 427 .

[0090] The third driving device 421 is specifically a motor. The third driving device 421 drives the connecting block to move through the first transmission belt 422 and the second transmission belt 424, and then drives the second movable frame 431 to move along the second guide rail 427, so that the longitudinal moving component 42 drives the transverse moving component 43 and the nozzle 44 to move along the length direction of the first conveyor line 1.

[0091] Specifically, the transverse driving module is arranged on the second movable frame 431 , and the transverse driving module can adopt a linear module. The driving end of the transverse driving module is connected to the nozzle 44 , and the transverse driving module drives the nozzle 44 to move along the width direction of the first conveyor line 1 .

[0092] To further illustrate, the ink cleaning mechanism 4 further includes an ink tank 46, a clean water tank 47 and a water delivery pipeline assembly 48, and the water delivery pipeline assembly 48 includes a fixed pipe 481, a first connecting hose 482, a second connecting hose and a water pump;

[0093] The ink tank 46 and the clean water tank 47 are both arranged at one side of the first conveying line 1, one end of the fixed pipe 481 is connected to the ink tank 46, the other end of the fixed pipe 481 is connected to the clean water tank 47, one end of the first connecting hose 482 is connected to the fixed pipe 481, the other end of the first connecting hose 482 is connected to the water inlet end of the water pump, the water outlet end of the water pump is connected to one end of the second connecting hose, the other end of the second connecting hose is connected to the nozzle 44, the first connecting hose 482 is arranged outside the lateral moving assembly 43, the second connecting hose and the water pump are both arranged inside the lateral moving assembly 43;

[0094] The fixed pipe 481 is provided with a first valve 4811 and a second valve 4812 . The first valve 4811 is provided between the connection between the ink tank 46 and the first connecting hose 482 , and the second valve 4812 is provided between the clean water tank 47 and the first connecting hose 482 .

[0095] By providing the ink tank 46, the clean water tank 47 and the water delivery pipeline assembly 48, when inkjet is required, the first valve 4811 is opened, the second valve 4812 is closed, and the ink in the ink tank 46 is pumped to the nozzle 44 for inkjet under the action of the water pump. When the ink on the surface of the sample 12 needs to be cleaned, the second valve 4812 is opened, the first valve 4811 is closed, and the cleaning water in the clean water tank 47 is pumped to the nozzle 44 under the action of the water pump to clean the ink on the surface of the sample 12.

[0096] Specifically, since the lateral moving component 43 needs to move along the first conveyor line 1, the nozzle 44 also needs to move along the width direction of the first conveyor line 1 driven by the lateral moving component 43. By setting the first connecting hose 482 and the second connecting hose, the first connecting hose 482 can move along with the movement of the lateral moving component 43, and the second connecting hose can move along with the movement of the nozzle 44.

[0097] Specifically, the ink may be a methylene blue solution.

[0098] Further explained, the ink coating cleaning mechanism 4 also includes a blow-drying component 49, and the blow-drying component 49 includes a fixed frame 491 and a plurality of blowing nozzles 492, the fixed frame 491 is fixedly set on the frame 41, the fixed frame 491 is set along the width direction of the first conveyor line 1, and the plurality of blowing nozzles 492 are arranged on the fixed frame 491 at intervals along the length direction of the fixed frame 491, and the blowing end of the blowing nozzle 492 is inclined toward the incoming direction of the sample 12 on the first conveyor line 1.

[0099] By setting the drying component 49, after the sample 12 is inkjetted and cleaned, the sample 12 continues to be transported on the first conveyor line 1, and the blowing nozzle 492 blows air toward the sample 12 to dry the moisture on the surface of the sample 12, so as to facilitate the subsequent observation of cracks. Since the blowing nozzles 492 are arranged at intervals along the length direction of the fixing frame 491, they can cover the width of the sample 12, ensuring that the clean water on the surface of the sample 12 is evenly blown dry. By setting the blowing end of the blowing nozzle 492 to be inclined toward the incoming direction of the sample 12 on the first conveyor line 1, under the conveying effect of the sample 12 and the blowing effect of the blowing nozzle 492, the moisture on the surface of the sample 12 can be dried more quickly, thereby improving the drying efficiency.

[0100] like Figure 7 and Figure 8 As shown, it is further explained that the observation mechanism 5 includes a mounting frame 51, a plurality of camera modules 52 and a plurality of first lighting lamps 53;

[0101] The mounting frame 51 is disposed on one side of the first conveyor line 1, and the camera modules 52 are arranged in an array on the mounting frame 51. The camera modules 52 include a bracket 521, an industrial camera 522, and a second illuminator 523. One end of the bracket 521 is fixedly connected to the mounting frame 51, and the other end of the bracket 521 is fixedly connected to the second illuminator 523. The second illuminator 523 is ring-shaped. The industrial camera 522 is fixedly disposed on the bracket 521, and the industrial camera 522 is located directly above the second illuminator 523.

[0102] The first lighting lamp 53 is fixedly mounted on the mounting frame 51 , and the first lighting lamp 53 is located between two rows of camera modules 52 .

[0103] By setting up a plurality of the industrial cameras 522, the cameras of the plurality of the industrial cameras 522 can realize the shooting of photos. Since the cracks on the surface of the ceramic slab may be relatively fine, and the specifications of the ceramic slab are relatively large, the plurality of the industrial cameras 522 can cover and shoot the entire ceramic slab, which is equivalent to dividing the surface area of ​​the ceramic slab. Each of the industrial cameras 522 shoots a smaller interval separately for easy observation, thereby ensuring the integrity of the test results. In addition, by setting up the first lighting lamp 53 and the second lighting lamp 523, the dual light source structure enables different light sources to illuminate the sample 12 from different angles, which can achieve a shadowless effect, avoid the appearance of shadows that affect the result judgment, and facilitate the before-and-after comparison of whether there are cracks on the surface of the sample 12.

[0104] Specifically, the camera modules 52 are arranged in four columns and two rows, the first lighting lamps 53 are in the shape of long strips, and the length direction of the first lighting lamps 53 is extended along the arrangement direction of the camera modules 52, so that the light source covers a wider area. The second lighting lamps 523 are in the shape of a ring, and the industrial camera 522 is located directly above the second lighting lamps 523 to prevent the second lighting lamps 523 from affecting the shooting of the industrial camera 522.

[0105] like Fig. 9 As shown, specifically, the heating mechanism 8 is a kiln, and a fan 81 is provided on the top of the heating mechanism 8.

[0106] The sample 12 is heated by a kiln, which can simulate the high temperature conditions that the sample 12 may encounter in actual use. Due to the restriction of air flow and the difference in heat transfer, there may be temperature differences inside the kiln. By arranging a fan 81 on the top of the heating mechanism 8, the air flow inside the kiln can be accelerated, so that the heat is more evenly distributed inside the kiln, thereby achieving uniform heating of the sample 12.

[0107] like Figure 1 , Fig.10 , Fig.11 and Fig.12 As shown, it is further explained that the first translation mechanism 10 and the second translation mechanism 11 have the same structure;

[0108] The first translation mechanism 10 includes a base 101, a mounting seat 102, a driving assembly 103, a translation belt 104 and a lifting driving device. The mounting seat 102 is arranged above the base 101, and the lifting driving device is fixedly arranged on the base 101. The driving end of the lifting driving device is fixedly connected to the bottom end surface of the mounting seat 102, and the lifting driving device drives the mounting seat 102 to move up and down.

[0109] The driving assembly 103 is fixedly arranged on the mounting seat 102, and the driving end of the driving assembly 103 is drivingly connected with the translation belt 104. The setting direction of the translation belt 104 is perpendicular to the first conveyor line 1 and the second conveyor line 2. The driving assembly 103 drives the translation belt 104 to rotate so as to convey the sample 12 along the width direction of the first conveyor line 1 and the second conveyor line 2;

[0110] A third translation mechanism 14 is respectively provided at the input end of the first conveying line 1 and the output end of the second conveying line 2 corresponding to the second translation mechanism 11, and the third translation mechanism 14 has the same structure as the second translation mechanism 11;

[0111] A fourth translation mechanism 15 is respectively provided at the output end of the first conveying line 1 and the input end of the second conveying line 2 corresponding to the first translation mechanism 10, and the fourth translation mechanism 15 has the same structure as the first translation mechanism 10;

[0112] The first conveyor line 1 and the second conveyor line 2 are respectively provided with a plurality of rollers 13 disposed at intervals, and the translation belt 104 of the third translation mechanism 14 and the translation belt 104 of the fourth translation mechanism 15 are both located between two of the rollers 13 .

[0113] Specifically, there are multiple translation belts 104, and the driving component 103 can adopt a combination of a motor, a belt and a gear. This driving structure is a conventional driving structure and will not be repeated here. The driving end of the driving component 103 is connected to a rotating shaft, and the translation belt 104 is wound around the rotating shaft and the roller of the mounting base 102. The driving component 103 drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the translation belt 104 to rotate, so as to transport the sample 12 along the width direction of the first conveyor line 1 and the second conveyor line 2.

[0114] Specifically, the translation belt 104 is located between the two rollers 13. By setting the third translation mechanism 14 and the fourth translation mechanism 15, when the sample 12 needs to be conveyed from the first conveyor line 1 to the second conveyor line 2, or the sample 12 needs to be conveyed from the second conveyor line 2 to the first conveyor line 1, the lifting drive device drives the mounting base 102 to rise, and at this time drives the translation belt 104 to rise between the two rollers 13 and lift the sample 12, so that the bottom surface of the sample 12 is separated from the rollers 13. At this time, the sample 12 is transported again, which can avoid the bottom wear of the sample 13 during the movement.

[0115] It should be noted that when the sample 12 is conveyed from the first conveyor line 1 to the second conveyor line 2, the translation belt 104 of the fourth translation mechanism 15 and the translation belt 104 of the first translation mechanism 10 rise to the same horizontal height to achieve stable conveyance of the sample 12; similarly, when the sample 12 is conveyed from the second conveyor line 2 to the first conveyor line 1, the translation belt 104 of the third translation mechanism 14 and the translation belt 104 of the second translation mechanism 11 rise to the same horizontal height to achieve stable conveyance of the sample 12.

[0116] Specifically, the loading mechanism 3 and the unloading mechanism 6 have the same structure, and the loading mechanism 3 and the unloading mechanism 6 can adopt the same movable gantry 72 and lifting adsorption assembly 73 as the first immersion mechanism 7 to realize adsorption loading and adsorption unloading of the sample 12.

[0117] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
