Description

Technical Field

[0001] The present invention belongs to the technical field of hollow brick processing and detection, and particularly relates to an automatic detection device for hollow brick processing and an automatic detection method therefor. Background Art

[0002] Hollow bricks are a kind of building consumables, which are different from solid bricks made by solid casting. Hollow bricks have a large number of hole structures, so the performance of hollow bricks in all aspects cannot reach that of solid bricks. However, due to their small material consumption, low cost, and light weight, they are still widely used in building construction. However, different from solid brick materials, hollow bricks can only be used as non-load-bearing structures of building structures.

[0003] Due to the extensive use of hollow bricks in construction, as well as the defects of small material consumption, low cost, and low performance of hollow bricks, the performance detection requirements for hollow bricks are relatively high. The specific reason is that although they are used in non-load-bearing structures, due to their small material consumption and low performance, only hollow bricks with performance meeting the standards can be used.

[0004] Therefore, in the actual production process, it is necessary to conduct sampling inspection on the produced hollow bricks to evaluate whether the performance of the produced hollow bricks is qualified.

[0005] The current detection method is to send the sample bricks into the laboratory for various performance tests on the sample bricks. However, due to the large production volume of brick materials, in the actual test process, in order to more scientifically reflect the qualification degree of the brick materials, there are certain requirements for the sampling volume. Therefore, the test can only be carried out in the workshop during the actual production process. The current test methods mainly include appearance detection, corrosion resistance detection, and pressure resistance detection.

[0006] However, due to the large sampling volume and the certain weight of hollow bricks, in the detection process, how to solve the detection of a large number of hollow bricks has become a major problem, and the detection mainly relies on manual operation, with very low efficiency and low detection accuracy.

[0007] With the development of production technology, the production efficiency of brick materials is very high. Therefore, if an automatic and efficient detection device cannot be provided to match the high-efficiency production line, it will not be able to meet the production needs. Summary of the Invention

[0008] Based on the above background, the purpose of the present invention is to provide an automatic detection device for hollow brick processing.

[0021] A lead screw motor is fixedly connected inside the second rotating seat. The lead screw motor is assembled and connected with a lead screw. The lead screw penetrates through the second rotating seat, and a guide rail rod cooperating with the lead screw is fixedly connected to the first rotating seat;

[0022] The lead screw is threadedly connected to a moving bracket, and the guide rail rod is slidably connected to a moving bracket. A rotating motor is fixedly connected to one side of the moving bracket, and a mounting seat is rotatably connected to the other side of the moving bracket. The output end of the rotating motor is fixedly connected to the mounting seat. A suction cup bracket is installed between the mounting seats, and a number of suction cups for grasping and sucking sample bricks are installed on the suction cup bracket.

[0024] Preferably, the climbing ladder mechanism includes a chain plate machine inclined upward, and a number of climbing ladder plates are fixedly connected to the chain plate machine. The material grabbing structure grabs the sample brick and places it on the climbing ladder plate.

[0025] Preferably, a corrosion resistance detection mechanism is installed at the discharge end of the chain plate machine;

[0026] The corrosion resistance detection mechanism includes a support plate. A sodium sulfate immersion detection cylinder is installed on one side of the support plate, and a landslide frame cooperating with the chain plate machine is fixedly connected to the top of the support plate. The sample brick falling from the climbing ladder plate slides down along the landslide frame into the sodium sulfate immersion detection cylinder;

[0027] A clean water immersion detection cylinder is installed on the other side of the support plate;

[0028] A base is fixedly connected to the bottom of the support plate, and a detection water tank is installed on the top of the base. The detection water tank is integrally formed with an independently provided first cavity and a second cavity. A first liquid pump and a second liquid pump are respectively installed in the first cavity and the second cavity. The first liquid pump pumps the sodium sulfate solution in the first cavity into the sodium sulfate immersion detection cylinder, and the second liquid pump pumps clean water onto the clean water immersion detection cylinder.

[0032] Preferably, the belt feeding structure includes a short belt conveyor arranged perpendicular to the support plate;

[0033] The frame of the short belt conveyor is fixed to the end of the pressure resistance detection table through a support steel frame; the discharge end of the short belt conveyor is located above the pressure resistance detection table;

[0034] The feeding end of the short belt conveyor is located below the suction cup body.

[0035] The present invention also discloses an automatic detection method for the above-mentioned automatic detection device for hollow brick processing, including the following steps:

[0036] (1) Feed the sample brick to the discharge end position of the sampling brick feeding mechanism through the sampling brick feeding mechanism;

[0037] (2) The grasping structure on the probe detection mechanism grasps and feeds the sample brick onto the detection structure. Through the detection structure, the sample brick rotates automatically on the detection structure. When the sample brick faces the high-definition camera on the detection structure, the high-definition camera captures the sample brick and transmits the captured picture to the background. The background compares the sample brick picture with the picture of the qualified product brick, including color and shape comparison detection;

[0038] When the sample brick rotates to face the flaw detection sensor, the flaw detection sensor detects the sample brick to check whether there is a damaged structure inside the sample brick;

[0039] When the sample brick rotates to face the contour measurement sensor, the contour measurement sensor detects the sample brick to check whether its appearance contour is qualified;

[0040] (3) After the detection is completed, the grasping structure grabs the sample brick again and feeds it onto the climbing ladder mechanism to feed it to the corrosion resistance detection mechanism;

[0041] The sample brick falls into the corrosion resistance detection mechanism and is immersed in a high-concentration sodium sulfate solution to detect its corrosion resistance;

[0042] After the detection is completed, the sample brick is grabbed again, soaked and cleaned with water, dried and weighed;

[0043] (4) The grasping structure grabs the sample brick again and sends it into the pressure resistance detection mechanism. Specifically, it grabs the sample brick and feeds it onto the feeding belt structure of the feeding structure. After the sample brick is fed from the belt feeding structure, it falls onto the pressure resistance detection table for pressure resistance detection.

[0044] The present invention has the following beneficial effects:

[0045] 1. A probe structure for detecting the sample brick is installed on the top of the detection table. Automatic detection is carried out through the probe structure. Specifically, the probe structure includes a high-definition camera, a flaw detection sensor, and a contour measurement sensor.

[0046] It realizes the color and shape comparison detection of the brick material, the detection of whether there is a damaged structure inside the sample brick, and the contour size detection of the brick material through the contour measurement sensor, and judges whether the dimensional accuracy of the brick material meets the standard. The above detection method not only realizes intelligent detection, but also can fully reflect the performance of the sample brick.

[0047] 2. During the working process, when the sample brick moves to the discharge end of the belt conveyor, driven by the gear motor, the first swivel base and the second swivel base carry the lead screw, the guide rail rod, the suction cup support, and synchronously turn towards the brick material. After turning until the suction cup on the suction cup support is above the brick material, then, driven by the lead screw, the suction cup support descends. When the height of the suction cup support decreases, at this time, driven by the rotary motor, after the suction cup support rotates to adjust the posture of the suction cup (ensuring that the suction cup can vertically adsorb the brick material), the brick material is sucked. Subsequently, the gear motor drives in the reverse direction, and the brick material is placed on the automatic turntable according to the above - mentioned reverse process and detected in the above - mentioned manner. After the detection is completed, the brick material is sucked again and prepared to enter the next process. The advantages of the above - mentioned structural design are as follows: Driven by the gear motor, the first swivel base, the second swivel base carry the lead screw, the guide rail rod, the suction cup support, and the rotary motor form a flexible arm that can arbitrarily adjust the posture of the suction cup. During the working process, regardless of the position of the sample brick, by adjusting the posture of the suction cup, it is convenient and stable to suck the sample brick.

[0048] 3. A number of vertically arranged ladder plates are fixedly connected to the chain - plate machine. When in the transmission state, the ladder plates move synchronously with the chain - plate machine. At this time, the sample bricks supported on the ladder plates climb up synchronously to the next detection section. By the above - mentioned transmission and transportation, the detection sample bricks not only have high movement stability, but also can keep the brick material from slipping during the movement, effectively avoiding the damage of the brick material caused by slipping during the transmission movement, which affects the subsequent detection accuracy.

[0049] 4. During the working process, under normal circumstances, the rotary arm is oriented left - right. When it is necessary to grab the soaked brick material from the sodium sulfate soaking detection cylinder, at this time, the valve on the pump pipe (an electromagnetic valve) is opened, and the first liquid pump pumps the sodium sulfate solution back into the water tank. At this time, driven by the motor, the rotary arm rotates to the horizontal posture. Then, the long - cylinder air cylinder drives the piston rod to descend, and the suction cup body grabs the brick material. Subsequently, driven by the long - cylinder air cylinder, the grabbed brick material is lifted, and the rotary arm rotates again to put the brick material into the clear - water soaking detection cylinder for soaking and cleaning to be completed.

[0050] By the above - mentioned method, during the corrosion resistance detection of the sample, the sample is grabbed in an automated manner and transferred between the corrosion liquid and the clear - water liquid. The above - mentioned structure realizes the automated corrosion resistance detection of the brick material. This detection method does not require manual operation and the mechanical structure automatically grabs. On the one hand, it improves the detection accuracy, and on the other hand, it avoids excessive human contact with the corrosive detection liquid. At the same time, the advantages of this method also lie in: The detection liquid (sodium sulfate solution) is automatically pumped, sucked, and automatically cleaned after inspection.

[0051] 5. A belt feeding structure cooperating with the grasping and sucking structure is installed at the feeding end position of the withstand voltage detection bench. After the sucker body grasps the brick material, the brick material falls onto the short belt conveyor and is conveyed by the short belt conveyor to fall onto the withstand voltage detection bench. At this time, the withstand voltage detection device detects the brick material. In this way, further automatic feeding detection is realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Embodiment 1

[0068] As Figures 1-10 shown, an automatic detection device for hollow brick processing includes a sampling brick feeding mechanism 1. The sampling brick feeding mechanism 1 includes a belt conveyor, and the belt conveyor is a conventional belt conveyor disclosed in the prior art.

[0069] During the working process, the sample bricks to be detected are stacked on the palletizing frame and sent to the feeding end position of the belt conveyor by a forklift. And the sampled sample bricks are loaded onto the belt conveyor one by one and enter the detection production line.

[0070] Specifically, a probe detection mechanism 2 is installed at the discharging end of the belt conveyor. The probe detection mechanism 2 includes a detection structure and a material grabbing structure installed on the detection structure.

[0071] Specifically, the detection structure includes a detection table 21 installed at the discharging end position of the belt conveyor; an automatic turntable 22 is installed on the top of the detection table 21. The automatic turntable 22 is a conventional automatically rotatable turntable disclosed in the prior art, and its main structure includes a turntable and a turntable motor installed at the bottom position of the turntable.

[0072] The sample brick is placed on the automatic turntable 22. Specifically, it is grabbed by the material grabbing structure and placed on the automatic turntable 22 for detection.

[0073] A probe structure 23 for detecting sample bricks is installed on the top of the above-mentioned detection table 21. Automated detection is carried out through the probe structure 23. Specifically, the probe structure 23 includes a high-definition camera, a flaw detection sensor, and a contour measurement sensor.

[0074] Among them, the high-definition camera is a conventional high-definition camera for conventional detection products in industrial production disclosed in the prior art, with the same principle as existing detection products. The high-definition camera captures the sample brick and transmits the captured picture to the background. The background compares the sample brick picture with the picture of the qualified product brick, including color and shape comparison detection.

[0075] At the same time, when the sample brick rotates on the automatic turntable 22 to face the flaw detection sensor, the flaw detection sensor detects the sample brick to check whether there is a damaged structure inside the sample brick. Among them, the flaw detection sensor is a detection sensor conventionally used for flaw detection of workpieces in industry disclosed in the prior art.

[0076] Internal detection of the brick material is achieved through the flaw detection sensor to determine whether the interior of the brick material is qualified.

[0077] When the sample brick rotates to the contour measurement sensor, the contour measurement sensor detects the sample brick to check whether its appearance contour is qualified. Among them, the contour measurement sensor is a measurement sensor conventionally used for detecting the contour of workpieces in industry disclosed in the prior art. Detection of the contour dimensions of the brick material is achieved through the contour measurement sensor to determine whether the dimensional accuracy of the brick material meets the standard.

[0078] Embodiment 2

[0079] As Figures 1-10 shown, on the basis of the structure of Embodiment 1, in order to realize grasping the brick material, the above-mentioned material grasping structure 24 includes a U-shaped bracket 241, and both ends of the U-shaped bracket 241 are fixedly connected to the side walls on both sides of the detection table 21.

[0080] Specifically, a first rotating seat 243 and a second rotating seat 242 are respectively rotatably connected to the left and right sides of the U-shaped bracket 241; a connecting shaft 2401 is fixedly connected between the first rotating seat 243 and the second rotating seat 242, and the connecting shaft 2401 is rotatably connected to the U-shaped bracket 241 (correspondingly, bearings are installed on both sides of the U-shaped bracket 241).

[0081] At the same time, according to the existing driving method for rotating the connecting shaft 2401, a driven gear 2403 is installed on the above-mentioned connecting shaft 2401, the driven gear 2403 meshes with a driving gear 24021, and a gear motor 2402 is installed on the driving gear 24021. The gear motor 2402 is mounted on the bottom of the detection table 21.

[0082] The gear motor 2402 is actuated to drive the connecting shaft 2401 to rotate, thereby causing the first swivel base 243 and the second swivel base 242 at both ends to rotate synchronously.

[0083] A lead screw motor is fixedly connected inside the second swivel base 242 (a cavity is provided inside the second swivel base 242, and the lead screw motor is installed inside the cavity, not shown in the figure). The lead screw motor is assembled and connected with a lead screw 244. The lead screw 244 passes through the second swivel base 242 (in accordance with the existing method, a lead screw 244 bearing is installed at the penetration position of the lead screw 244 and the second swivel base 242, and the lead screw 244 is rotationally connected to the connecting shaft 2401 bearing). Correspondingly, a guide rail rod 249 that cooperates with the lead screw 244 is fixedly connected to the first swivel base 243.

[0084] The lead screw 244 is threadedly connected with a moving bracket, and the guide rail rod 249 is slidably connected with a moving bracket 2441. A rotary motor 245 is fixedly connected to the left moving bracket 2441. A mounting seat is rotatably connected to the right moving bracket 2441 (the mounting seat is rotatably connected to the moving bracket 2441 through a fixedly installed rotating shaft). The output shaft of the rotary motor 245 is fixedly connected to the mounting seat. A suction cup bracket 246 is installed between the lower ends of the mounting seat. A plurality of suction cups 248 for grasping and sucking sample bricks are installed on the suction cup bracket 246. During the actual working process, an additional suction cup bracket 247 is installed between the upper ends of the mounting seat. A plurality of suction cups 248 are installed on the additional suction cup bracket 247. Different from the suction cups at the lower position, suction cup bodies with different adsorption forces are designed to cope with detection sample bricks with greater weight and larger models.

[0085] During the working process, when the sample brick moves to the discharge end of the belt conveyor, at this time, driven by the gear motor 2402, the first swivel base 243 and the second swivel base 242 carry the lead screw 244, the guide rail rod 249, and the suction cup bracket 246 and turn synchronously towards the brick material until the suction cups on the suction cup bracket 246 are located above the brick material. Subsequently, driven by the lead screw 244, the suction cup bracket 246 descends in height.

[0086] After the height of the suction cup bracket 246 drops, at this time, driven by the rotary motor 245, the suction cup bracket 246 rotates to adjust the posture of the suction cups (ensuring that the suction cups 248 can vertically adsorb to the brick material) and then sucks the brick material.

[0087] Subsequently, the gear motor 2402 is driven in the reverse direction, and the brick material is placed on the automatic turntable 22 according to the above opposite process and detected in the above manner.

[0088] After the detection is completed, the brick material is sucked again and prepared to enter the next process.

[0089] The advantages of the above structural design are as follows:

[0090] Driven by the gear motor 2402, the first turntable 243 and the second turntable 242 carry the lead screw 244, the guide rail rod 249, the suction cup bracket 246, the suction cup bracket 246, and the rotary motor 245 to form a flexible arm that can arbitrarily adjust the posture of the suction cup 248, so as to realize that no matter where the sample brick is during the working process, the suction cup posture can be adjusted to conveniently and stably suck the sample brick.

[0091] When the sample brick is sucked and placed on the automatic turntable 22, in order to avoid hitting the sample brick during the feeding process and affecting the detection accuracy, such as the appearance of the brick material being damaged due to the collision, an elastic buffer structure 221 is fixedly connected to the top of the above-mentioned automatic turntable 22, and the sample brick is placed on the elastic buffer structure 221.

[0092] The elastic buffer structure 221 is composed of rubber rings formed by several concentric circles, and the brick material is placed on the top of the rubber ring.

[0093] Embodiment 3

[0094] As Figures 1-10 shown, on the basis of the structure of Embodiment 2 in this embodiment, when the detection of the sample brick is completed, in order to facilitate the sample brick to enter the next detection process, at this time, the suction cup bracket 246 and the suction cup 248 grab the brick material again, and the gear motor 2402 drives in the reverse direction to turn the brick material forward and close to the climbing ladder mechanism 3. And, the rotary motor 245 rotates to adjust the posture of grasping and sucking the sample brick to facilitate placing it on the climbing ladder mechanism 3.

[0095] Specifically, a climbing ladder mechanism 3 is arranged at the discharging end position of the probe detection mechanism 2. The grasping structure 24 grabs the detected sample brick onto the climbing ladder mechanism 3.

[0096] Embodiment 4

[0097] As Figures 1-10 shown, on the basis of the structure of Embodiment 3 in this embodiment, the climbing ladder mechanism 3 includes a chain plate machine arranged obliquely upward, which is the same as the structure of the existing chain plate machine. The chain plate machine includes a frame 35 and upper and lower chain plate wheels 33 and 37 rotatably connected to the upper and lower ends of the frame 35. The upper chain plate wheel 33 and the lower chain plate wheel 37 are driven by a chain plate 31.

[0098] According to the transmission method of the existing chain plate machine, the upper chain plate wheel 33 and the lower chain plate wheel 37 are driven by a transmission structure. Specifically, it includes belt pulleys 361 installed on the upper chain plate wheel 33 and the lower chain plate wheel 37, and the belt pulleys 361 are driven by a transmission belt. A driven belt pulley 3611 is fixedly installed on the belt pulley 361 at the upper end position, and a belt pulley motor 36 is arranged below the driven belt pulley 3611. The output shaft of the belt pulley motor 36 is installed with a driving belt pulley, and the driven belt pulley 3611 and the driving belt pulley are driven by a belt.

[0099] Meanwhile, a number of vertically arranged ladder plates 32 are fixedly connected to the chain conveyor. After the material grabbing structure 24 grabs the sample bricks, it places the bricks on the ladder plates 32. The ladder plates 32 are plastic plates.

[0100] When in the transmission state, the ladder plates 32 move synchronously with the chain conveyor. At this time, the sample bricks supported on the ladder plates 32 climb up synchronously to the next detection section.

[0101] By transporting and detecting the sample bricks through the above-mentioned transmission, not only is the movement stability high, but also the bricks do not slip during the movement process, effectively avoiding the damage of the bricks caused by slipping during the transmission movement and affecting the subsequent detection accuracy.

[0102] Embodiment 5

[0103] As Figures 1-10 shown, on the basis of the structure of Embodiment 4, a corrosion resistance detection mechanism 4 is assembled and connected at the discharge end position of the climbing ladder mechanism 3 (that is, the corrosion resistance detection mechanism 4 is installed at the discharge end position of the chain conveyor), and the sample bricks fall into the corrosion resistance detection mechanism 4 for corrosion resistance performance testing.

[0104] The corrosion resistance detection of the bricks is realized through the corrosion resistance performance test.

[0105] Specifically, a grasping and sucking structure 44 is assembled and connected to the corrosion resistance detection mechanism 4. Specifically, the corrosion resistance detection mechanism 4 includes a support plate 41. A sodium sulfate immersion detection cylinder 42 is installed at the rear side of the support plate 41. A landslide frame cooperating with the chain conveyor is fixedly connected to the top of the support plate 41. When the ladder plates 32 on the chain conveyor carry the bricks to move to the next stroke, at this time, the bricks slide down and fall into the landslide frame and enter the sodium sulfate immersion detection cylinder 42 from the landslide frame.

[0106] Due to the limitation of the caliber size of the sodium sulfate immersion detection cylinder 42, the bricks can only fall horizontally and lie flat into the sodium sulfate immersion detection cylinder 42 without tipping over.

[0107] During the actual working process, a corrosion-resistant lining such as a corrosion-resistant rubber lining is lined on the inner side wall of the sodium sulfate immersion detection cylinder 42 to further protect the detected bricks.

[0108] A clean water immersion detection cylinder 43 is installed on the other side of the above-mentioned support plate 41. After the corrosion test is completed, the bricks are sent into the clean water immersion detection cylinder 43 for cleaning to prepare for subsequent detection.

[0109] Specifically, a base is fixedly connected to the bottom of the support plate 41, and a detection water tank 45 is installed on the top of the base. An independently provided first cavity 451 and a second cavity 452 are integrally formed on the detection water tank 45. In this way, a first liquid pump and a second liquid pump are respectively installed in the first cavity 451 and the second cavity 452. The first liquid pump pumps the sodium sulfate solution in the first cavity 451 into the sodium sulfate immersion detection cylinder 42, and the second liquid pump pumps the clear water onto the clear water immersion detection cylinder 43.

[0110] Specifically, pump feed pipes A are respectively installed at the water outlet ends of the first liquid pump and the second liquid pump (in the existing way, valves are installed on the pump feed pipes). The pump feed pipes A penetrate and are connected to the lower ends of the detection cylinders to realize the pumping of sodium sulfate and clear water.

[0111] After the brick material falls into the sodium sulfate immersion detection cylinder 42 and is soaked for a period of time, the brick material is grabbed and sent into the clear water immersion detection cylinder 43 for cleaning.

[0112] Embodiment 6

[0113] As Figures 1-10 shown, on the basis of the structure of Embodiment 5, a grasping and sucking structure 44 is fixedly connected to the top of the above-mentioned support plate 41; the grasping and sucking structure 44 includes a motor 441, and the output shaft of the motor 441 is fixedly connected to a rotating arm 442.

[0114] At the same time, long cylinder cylinders 443 are respectively installed at both ends of the rotating arm 442, and a suction cup body 444 for grasping the sample brick is installed on the piston rod of the long cylinder cylinder 443.

[0115] Normally, the rotating arm 442 is in the left-right orientation. When it is necessary to grab the soaked brick material from the sodium sulfate immersion detection cylinder 42, the valve on the pump feed pipe is opened (it is an electromagnetic valve), and the first liquid pump pumps the sodium sulfate solution back into the water tank. At this time, the rotating arm 442 rotates to a horizontal position under the drive of the motor. At this time, the long cylinder cylinder 443 drives the piston rod to descend, and the suction cup body 444 grabs the brick material. Subsequently, under the drive of the long cylinder cylinder 443, the grabbed brick material is lifted, and the rotating arm 442 rotates again to put the brick material into the clear water immersion detection cylinder 43 for soaking and cleaning to be completed.

[0116] After the soaking and cleaning are completed, the long cylinder cylinder 443 drives again to grab and lift the brick material, and then the operator dries and weighs the brick material. Specifically, in the existing way, a weighing platform (not shown in the figure) is fixed on the left side of the support plate 41, a balance (not shown in the figure) is placed on the weighing platform, and a drying platform (not shown in the figure) is installed on the drying platform, and a dryer (not shown in the figure) is installed on the drying platform to realize automatic drying and weighing.

[0117] Subsequently, the brick material is grabbed again and enters the next process.

[0118] Or directly perform manual drying and weighing.

[0119] The above structure realizes the automatic corrosion resistance detection of brick materials. This detection method does not require manual operation, and the mechanical structure automatically grabs. Firstly, it improves the accuracy of detection, and secondly, it avoids excessive human contact with corrosive detection liquid. At the same time, the advantages of this method also lie in: the detection liquid (sodium sulfate solution) is automatically pumped, sucked, and automatically cleaned after inspection.

[0120] Embodiment 7

[0121] As Figures 1-10 shown, on the basis of the structure of Embodiment 6 in this embodiment, a pressure resistance detection mechanism 5 is arranged at the discharge end position of the corrosion resistance detection mechanism 4. The pressure resistance test of the corroded brick material is realized through the pressure resistance detection mechanism 5 to further judge the compressive performance of the brick material.

[0122] Specifically, the pressure resistance detection mechanism 5 includes a pressure resistance detection table 52. At the same time, according to the existing method for detecting the pressure of brick materials, a pressure resistance detection device (not shown in the figure) is installed at the top position of the pressure resistance detection table 52. The pressure resistance detection device is a conventional pressure detection device disclosed in the prior art, with the same structure and method as the existing pressure resistance detection. The main structure of the pressure resistance detection device includes a hydraulic cylinder for detection and a pressure sensor installed at the bottom of the plunger rod of the hydraulic cylinder. During the detection process, the pressure sensor presses against the brick material and squeezes the brick material until it breaks. The extrusion force is measured by the pressure sensor, and the pressure resistance degree of the brick material is judged by comparing the obtained extrusion force data with the extrusion force of qualified brick materials.

[0123] Specifically, a belt feeding structure matched with the grasping and sucking structure 44 is installed at the feeding end position of the pressure resistance detection table 52.

[0124] The belt feeding structure includes a short belt conveyor 51 vertically arranged with the support plate 41 (installed on the right side of the support plate 41, and structures such as weighing and drying are installed on the left side of the support plate 41); the short belt conveyor 51 is a belt conveyor disclosed in the prior art, which is a small-size belt conveyor for conveying brick materials.

[0125] The frame of the short belt conveyor 51 is fixed at the end of the pressure resistance detection table 52 through a support steel frame 53; the discharge end of the short belt conveyor 51 is located above the pressure resistance detection table 52; the feeding end of the short belt conveyor 51 is located at the lower end of the suction cup body 444.

[0126] After the suction cup body 444 grabs the brick material, the brick material falls onto the short belt conveyor 51 and is conveyed by the short belt conveyor 51 and falls onto the pressure resistance detection table 52. At this time, the pressure resistance detection device detects the brick material.

[0127] After the detection is completed, the operator cleans the pressure resistance detection table 52 to facilitate the next detection of the brick material.

[0128] During the actual working process, an automatic cleaning device (not shown in the figure) can be installed on the pressure resistance testing bench 52. For example, a push plate is driven by a cylinder to push away the broken brick materials after testing, which is convenient for releasing space.

[0129] The above structure enables automatic feeding to the pressure resistance testing after the corrosion resistance testing is completed. The whole process does not require manual operation, which greatly improves the testing efficiency.

[0130] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
