Description

Technical Field

[0001] This invention relates to the field of cement physical testing technology, specifically to a cement mortar strength testing system. Background Technology

[0002] Cement mortar strength testing is a mandatory indicator for cement companies before cement products leave the factory. Cement companies must test the flexural and compressive strength of cement in accordance with the requirements of the national standard GB / T17671. The test results directly determine the grade of cement.

[0003] Currently, cement mortar strength testing mainly relies on manual testing. The main steps are as follows: First, a certain amount of water is placed in a mixing pot, then a certain amount of cement is taken from the sample bucket and placed in the mixing pot. Next, standard sand is poured into the mixer for later use. The mixing pot is then placed in the mixer for mixing, and standard sand is automatically added during the mixing process. The mixture is stirred into cement mortar according to national standards. Basic information about the incoming cement powder is recorded. The cement mortar is then poured into a triple mold and compacted on a vibrating table. After compaction, the mold is leveled and wiped. The triple mold is then placed in a wet curing chamber for wet curing. After 24 hours of wet curing, the mold is demolded and then placed in a water curing chamber for water curing. Basic information about the test blocks is recorded. After water curing, flexural and compressive strength tests are conducted and the results are recorded. During this period, the tooling used is cleaned, oiled, and wiped clean in preparation for the next mortar strength test. Because each cement production line has to perform a large number of test molds every day, and each group needs to weigh cement powder and water, record incoming cement powder, record water curing of test blocks, and record test results, the existing manual recording method is prone to errors and cannot deeply organize data from multiple consecutive days, making it inconvenient for subsequent traceability and observation comparison. Summary of the Invention

[0004] This invention provides a cement mortar strength testing system to solve the problems of existing testing systems that rely on manual recording of various information, are prone to errors, and are inconvenient for subsequent traceability and observation comparison.

[0005] This invention provides a cement mortar strength testing system, comprising: The sample preparation island is suitable for mixing and stirring the weighed materials and then pouring them into the mold to prepare cement samples. It includes a first robotic arm, a wet curing mechanism, and a cement sample demolding mechanism. The sample bucket used to hold the materials is equipped with a first information storage structure, and the mold is equipped with a second information storage structure. After the first robotic arm grabs the mold and reads the information in the second information storage structure, it is placed in the wet curing mechanism for wet curing. After wet curing is completed, it is sent to the cement sample demolding mechanism for demolding and the cement sample is transported to the test island. The test island is suitable for testing and recording the test results of cement samples after water curing. It includes a second robotic arm, a water curing box inlet and outlet exchange mechanism, and a sample flexural and compressive strength mechanism. The second robotic arm puts the cement sample into the first water curing box equipped with a third information storage structure, and then transports it to the water curing island through the water curing box inlet and outlet exchange mechanism. The water-cured cement sample is then transported to the sample flexural and compressive strength mechanism for testing. The water curing island is suitable for water curing cement samples. It includes a third robotic arm and a second water curing box equipped with a fourth information storage structure. The third robotic arm puts the first water curing box containing the cement sample into the second water curing box.

[0006] Beneficial Effects: The cement mortar strength testing system provided by this invention features a first information storage structure on the sample bucket to record cement material information, and a second information storage structure on the mold to trace the mold's movement by reading information from the second information storage structure. A second robotic arm grasps and scans the first curing box before placing the cement sample into it, thus binding the information between the first curing box, the sample bucket, and the mold. The second robotic arm scans and records information each time it grasps the first curing box, ensuring accuracy throughout the entire preparation process. A third robotic arm also scans and records information each time it grasps the first curing box, and simultaneously scans the second curing box, binding the information between the two. This achieves accurate recording of all information during cement mortar molding, wet curing, demolding, water curing, and testing, facilitating subsequent traceability. Furthermore, it allows for in-depth processing of data recorded over multiple days for easy observation and comparison.

[0007] In one optional implementation, the first, third, and fourth information storage structures are all QR codes, and the second information storage structure is a chip or RFID.

[0010] The test mold scanning detection structure scans the test molds before and after wet curing to ensure the accuracy of information recording, ensure that the information of the test molds transferred to the next station is correct, and prevent information confusion caused by too many test molds.

[0011] In one optional embodiment, the cement sample demolding mechanism includes a demolding and transfer positioning structure, a demolding structure, and a marking structure. The demolding and transfer positioning structure is suitable for positioning the mold after wet curing. After the demolding structure demolds the mold, the marking structure marks the cement sample.

[0012] Immediately after demolding the cement sample from the mold, mark it and record the information of the cement sample to facilitate manual inspection in case of abnormalities or to facilitate routine manual sampling.

[0013] In one optional embodiment, the sample preparation island further includes a standard sand bag cutting mechanism, which includes a standard sand hopper, a forklift loading structure located below the standard sand hopper, a suction cup shaking structure located on one side of the standard sand hopper, and a bag cutting structure. A weighing sensor is provided below the standard sand hopper, and a vibrator is provided below the bag cutting structure. The suction cup shaking structure is adapted to pick up the standard sand bags in the standard sand hopper, and the bag cutting structure is adapted to cut the standard sand bags and transport them to the standard sand bowl.

[0014] The weighing sensor continuously weighs the standard sand in the standard sand bin to determine the descent depth of the suction cup shaking structure, facilitating the retrieval of the standard sand bag; the vibrator is used to send all the standard sand that falls onto the bag-cutting structure into the standard sand bowl; the suction cup shaking structure is used to transport all the standard sand in the standard sand bag into the standard sand bowl, thereby reducing the waste of standard sand and saving costs.

[0015] In one alternative embodiment, the standard sand cutting bag mechanism further includes a waste bag box structure and a standard sand weighing structure, wherein the standard sand weighing structure is signal-connected to the suction cup shaking structure to place the standard sand waste bag into the waste bag box structure.

[0016] Once all the standard sand in the sandbag is fed into the standard sand bowl, the waste standard sand bag is promptly recycled, further reducing costs.

[0017] In one optional embodiment, the test island further includes a sample exchange mechanism and a sample draining mechanism located on the side of the water curing box inlet and outlet exchange mechanism. The sample exchange mechanism is adapted to place the first water curing box after it has been cleaned and scanned, and the sample draining mechanism is adapted to place the cement sample after water curing and scanning, and drain it.

[0018] The cement sample was placed into the first curing box after it was cleaned and drained. This process prevented impurities in the first curing box from contaminating the cement sample and ensured the accuracy of subsequent tests.

[0019] In one optional embodiment, the hydroponic island further includes a second hydroponic box cleaning and exchange mechanism, a hydroponic box cleaning mechanism disposed on one side of the second hydroponic box cleaning and exchange mechanism, and a hydroponic tank.

[0020] The second water-growing box cleaning and exchange mechanism serves as a transfer station for the second water-growing boxes to be cleaned and after cleaning, making it easy to operate. The water-growing tank is used to centrally place the second water-growing boxes, making the entire device structure more compact.

[0022] After the high-pressure cleaning positioning and transfer structure transports the test mold to the cleaning station, the cover closes to the opening of the high-pressure cleaning tank, thus forming a closed cleaning space to prevent cleaning water from splashing. The test mold buffer rack is used to place the test molds to be processed, and the sample barrel buffer structure is used to place the sample barrels. When it is necessary to grab the sample barrel inside the sample barrel buffer structure, the outer sample barrel can be placed on the sample barrel temporary buffer rack for buffering.

[0023] In one optional embodiment, the sample preparation island further includes a lid-opening and material-retrieving mechanism, which includes a bucket clamping structure and a lid-opening and material-grabbing structure and a direct vibration feeding structure located on one side of the bucket clamping structure. The direct vibration feeding structure feeds the powdered cement into the cement bowl and weighs it.

[0024] The clamping structure is used to clamp and position the sample barrel, while the opening and material-grabbing structure is used to open the lid of the sample barrel and retrieve the material, thereby automating the material retrieval process. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The current cement mortar strength testing system relies on a few people to prepare samples, completing a maximum of thirty samples in half a day. The process includes material handling, weighing, mixing, cleaning and high-pressure cleaning, drying, oiling, flexural and compressive strength testing, and recording the results. The process is extensive, relatively cumbersome, and involves a large amount of manual labor, which is time-consuming and labor-intensive. Furthermore, manual sampling results vary greatly due to differences in personnel operation or techniques. In addition, manual recording of various information is prone to errors and is inconvenient for subsequent traceability and observation comparison.

[0030] The following is combined Figures 1 to 23 Embodiments of the present invention are described.

[0031] According to an embodiment of the present invention, a cement mortar strength testing system is provided, comprising: Sample preparation island 1 is suitable for mixing and stirring the weighed materials and then pouring them into mold 5 to prepare cement samples. It includes a first robot arm 101, a wet curing mechanism 102, and a cement sample demolding mechanism 103. The sample bucket 4 used to hold the materials is provided with a first information storage structure, and the mold 5 is provided with a second information storage structure. After the first robot arm 101 grabs the mold 5 and reads the information in the second information storage structure, it is placed in the wet curing mechanism 102 for wet curing. After wet curing, it is sent to the cement sample demolding mechanism 103 for demolding and the cement sample is transported to test island 2. Test island 2 is suitable for testing and recording test results of cement samples after water curing. It includes a second robot 201, a water curing box inlet and outlet exchange mechanism 202, and a sample flexural and compressive strength mechanism 203. The second robot 201 puts the cement sample into the first water curing box 6 equipped with a third information storage structure, and transports it to the water curing island 3 through the water curing box inlet and outlet exchange mechanism 202. The water-cured cement sample is then transported to the sample flexural and compressive strength mechanism 203 for testing. The water curing island 3 is suitable for water curing cement samples. It includes a third robotic arm 301 and a second water curing box 302 equipped with a fourth information storage structure. The third robotic arm 301 places the first water curing box 6 containing the cement sample into the second water curing box 302. After water curing is completed, the second water curing box 302 is placed at the water curing box inlet / outlet exchange mechanism 202.

[0032] refer to Figure 1 and Figure 2 The sample preparation island 1, testing island 2, and water curing island 3 are arranged linearly. Sample preparation island 1 is mainly used for preparing cement samples. Testing island 2 is used to transfer cement samples between the sample preparation island and water curing island 3, and to perform flexural and compressive strength tests on the water-cured cement samples. Water curing island 3 is used for water curing the cement samples. It also includes an inlet pipe 7 and an outlet pipe 8 that connect the sample preparation island 1, testing island 2, and water curing island 3. The inlet pipe 7 has an inlet 701, and the outlet pipe 8 has an outlet 801 to provide cleaning water and discharge wastewater. (Reference) Figures 17 to 23 The tooling used in cement sample preparation and testing includes a sample bucket (4), a cement bowl, a standard sand bowl, a mixing pot, a mold (5), a funnel, and a first curing box (6). Its main function is to transfer materials during cement sample preparation, curing, and testing. (Reference) Figure 3 The first robotic arm 101 includes a ground-rail robotic arm structure 1011 and a robotic arm controller 1012, a first gripper 1013, a second gripper 1014, a third gripper 1015, and a leveling fixture 1016, which are sequentially arranged on the ground-rail robotic arm structure 1011. The ground-rail robotic arm structure 1011 provides a wider gripping space for the first robotic arm 101. The robotic arm controller 1012 is used to control the movements of the first gripper 1013, the second gripper 1014, and the third gripper 1015. The first gripper 1013 is mainly used for gripping standard sand bags and waste bag boxes when feeding standard sand. The second gripper 1014 is mainly used for gripping sample bucket 4 and waste bucket when feeding sample bucket 4. The third gripper 1015 is mainly used for gripping test mold 5, cement bowl, and standard sand bowl. The leveling fixture 1016 is mainly used for evenly leveling the mortar in test mold 5 after cement mortar is poured.

[0033] refer to Figure 2 and Figure 13The sample preparation island 1 also includes a stirring, cleaning, and vibration mechanism 104. The stirring, cleaning, and vibration mechanism 104 includes a first frame plate 1041 and a weighing and water-adding structure 1042, a scraping and cleaning structure 1043, a vibration table structure 1044, a leveling tool cleaning structure 1045, a water-adding structure 1046, a mixer 1047, a mixing pot turning structure 1048, a sealing and rinsing structure 1049, a booster pump structure 1050, and a mixing pot transfer structure 1040. The first frame plate 1041 serves as the outer frame of the machine, providing a platform for the operation of various structures on the machine. The mixing pot transfer structure 1040 transfers the mixing pot to the vicinity of the weighing and water-adding structure 1042 to add a measured amount of water. Then, the mixing pot is transferred to the powder cement feeding position to add powder cement. Finally, it is transferred to the mixing position of the mixer 1047 to start sand addition and mixing, so that the material in the mixing pot becomes cement mortar. The mixing is carried out in accordance with the requirements of the national standard GB / T 17671-2021: According to the national standard, the mixing process will be stopped for 90 seconds. During the stop, the mixing pot transfer structure 1040 carries the mixing pot to the center of the material turning position of the mixing pot turning structure 1048 to turn the material, so as to turn the mortar at the bottom of the mixing pot to the top. After turning the material, the mixing pot transfer structure 1040 carries the mixing pot to continue mixing in the mixer 1047. After mixing, the mixing pot transfer structure 1040 carries the mixing pot to the vibrating table structure 1044. Cement mortar is poured into the mold 5 of the vibrating table structure 1044 through a funnel. During the pouring process, the scraper blades of the scraper cleaning structure 1043 enter the mixing pot. The scraper blades then rotate, scraping off the mortar adhering to the inner wall of the mixing pot, causing it to fall into the mold 5. Afterward, the scraper blades of the scraper cleaning structure 1043 are retracted, and then the scraper cleaning structure 1043 automatically cleans and dries the scraper blades. After the pouring is completed, the robotic arm gripping system quickly switches to the leveling fixture 1016, and begins the leveling action on the mold 5, so that the mortar inside is evenly distributed in the three cavities of the mold 5. After leveling is completed, the leveling fixture 1016 is transported to the leveling fixture cleaning structure 1045 for cleaning. Simultaneously, the mixing pot transfer structure 1040 carries the mixing pot to the vicinity of the water addition structure 1046 for inner wall cleaning. Then, a certain amount of water is added at the water inlet structure. The mixing pot transfer structure 1040 then carries the mixing pot to the mixer 1047 and the mixing pot tipping structure 1048 to clean the mixing blades and tipping blades. That is, the mixing blades and tipping blades automatically rotate in the mixing pot filled with clean water, and the mortar is washed away through centrifugal force and the relative flushing of the water. The mixing pot transfer structure 1040 then pours out the water from the mixing pot, and then carries the mixing pot to the capping and rinsing structure 1049 for inner and outer wall rinsing and drying. Finally, the mixing pot is transferred to the weighing and water addition structure 1042 to await water addition.

[0034] refer to Figure 2 and Figure 14The sample preparation island 1 also includes a mold leveling mechanism 105, which includes a second frame plate 1051 and a mold support lifting structure 1052, a two-axis transfer structure 1053, an upper cover pressing and rinsing structure 1054, a receiving plate rinsing structure 1055, and a receiving rinsing structure 1056, all mounted on the second frame plate 1051. The second frame plate 1051 serves as the outer frame of the machine, providing a running platform for the various structures on the machine. When the mold support lifting structure 1052 is in the raised state, the first robot arm 101 grabs the mold to be leveled and places it into the mold placement area of ​​the mold support lifting structure 1052. Then, the mold support lifting structure 1052 descends, the receiving rinsing structure 1056 extends to position the mold, and the two-axis transfer structure 1053 levels the mold, scraping excess mortar onto the receiving plate. Afterwards, the leveling component of the two-axis transfer structure 1053 remains at the leveling and cleaning position, the upper cover pressing and rinsing structure 1054 is pressed down onto the test mold, the receiving and rinsing structure 1056 is retracted, and at the same time, the receiving plate rinsing structure 1055, the receiving and rinsing structure 1056, and the upper cover pressing and rinsing structure 1054 begin rinsing, cleaning and drying the receiving plate, the leveling component, the area around the test mold, and other areas. Then, the upper cover pressing and rinsing structure 1054 rises, the test mold support lifting structure 1052 also rises, and the robotic gripping system grasps the test mold to the next station.

The third frame plate 1061 serves as the outer frame of the machine, providing an operating platform for the various structures on the machine. When the first robot arm 101 picks up the funnel from the vibration table structure 1044 of the stirring and cleaning vibration mechanism 104 to the funnel cleaning placement position of the funnel cleaning structure, the upper cover sheet metal rinsing structure 1064 descends to form a closed space with the lower cover sheet metal rinsing structure 1062. Then, the internal funnel rinsing structure 1063 begins to rinse the funnel, cleaning the mortar in the funnel and drying it. Then, the upper cover rinsing structure 1049 rises, and the first robot arm 101 picks up the funnel and places it on the vibration table structure 1044 of the stirring and cleaning mechanism for later use.

The fourth frame plate 1071 serves as the outer frame of the machine, providing an operating platform for the various structures on the machine. The first three-axis gripping structure 1074 clamps the cleaned and dried upper mold vertical and horizontal plates to the first oiling structure 1072 and the second oiling structure 1075 for oiling, and then places them at the upper mold closing structure 1073 for mold closing. Afterwards, the first three-axis gripping structure 1074 places the cleaned and dried lower mold at the mold closing and transfer structure 1077. After positioning, the first screw tightening structure 1076 tightens the screws on the lower mold to the upper mold, achieving mold closing of the upper and lower molds. The closed mold is placed at the corresponding position on the sample preparation island 1. After the stirring, cleaning, and vibration mechanism 104 gives a signal to remove the mold, the first robotic arm 101 grips the mold and moves it to the oil spraying structure 1078 for oil spraying. After oil spraying, it is transported to the vibration table structure 1044 of the stirring, cleaning, and vibration mechanism 104.

A second robotic arm 201 grasps the first curing box 6 and scans its code before placing the cement sample into it, thus binding the information of the first curing box 6 with the sample bucket 4 and the mold. The second robotic arm 201 scans and records the code each time it grasps the first curing box 6, ensuring information accuracy throughout the entire preparation process. A third robotic arm 301 also scans and records the code each time it grasps the first curing box 6, and simultaneously scans the code of the second curing box 302, binding the information of the first and second curing boxes 6 and 302. This achieves accurate recording of all information during the cement mortar molding, wet curing, demolding, water curing, and testing processes, facilitating subsequent traceability. It also allows for in-depth processing of data recorded over multiple days for easy observation and comparison.

[0038] In one embodiment, the first, third, and fourth information storage structures are all QR codes, and the second information storage structure is a chip or RFID.

Each mold positioning support frame 1023 has an acrylic cover 1024 for the wet curing mold to move up and down. A solenoid valve group 1025 of the wet curing machine is located on one side of the mold scanning and detection structure 1022. The main body 1021 of the wet curing chamber provides a closed constant temperature and humidity environment for the entire wet curing process. The solenoid valve group 1025 of the wet curing machine provides a stable air source and control unit for the acrylic cover 1024 for the wet curing mold to move up and down. When the first robotic arm 101 picks up the test mold to be wet-cured and scans it at the test mold scanning and detection mechanism, it checks whether there is any leakage. If there is no leakage, it is placed in the corresponding position of the test mold positioning support frame 1023. Then, the wet-curing test mold moves up and down and the acrylic cover 1024 falls down. At the same time, the first robotic arm 101 takes out another wet-cured test mold from the test mold positioning support frame 1023, scans it at the test mold scanning and detection structure 1022, and then transports it to the next station. Then, the wet-curing test mold moves up and down and the acrylic cover 1024 closes. If the test mold is found to be leaking grout, the first robotic arm 101 places it in the grout-leaking test mold placement position, waiting for manual handling.

[0043] The test mold scanning detection structure 1022 scans the test molds before and after wet curing to ensure the accuracy of information recording, ensure that the information of the test molds transferred to the next station is correct, and prevent information confusion caused by too many test molds.

[0044] In one embodiment, the cement sample demolding mechanism 103 includes a demolding transfer and positioning structure 1031, a demolding structure 1032, and a marking structure 1033. The demolding transfer and positioning structure 1031 is adapted to position the mold after wet curing. After the demolding structure 1032 demolds the mold, the marking structure 1033 marks the cement sample.

[0045] refer to Figure 5The cement sample demolding mechanism 103 also includes a fifth frame plate 1034 and a second screw tightening structure 1035, a demolding sample transfer structure 1036, a second three-axis gripping structure 1037, and a lower mold direction adjustment structure 1038, all mounted on the fifth frame plate 1034. The fifth frame plate 1034 serves as the outer frame of the machine, providing a platform for the operation of various structures on the machine. When the first manipulator 101 grips the wet-cured sample mold and places it in the corresponding position of the demolding transfer positioning structure 1031, the demolding transfer positioning structure 1031 transfers it to the upper and lower mold separation position, positions and presses it, then the second three-axis gripping structure 1037 transfers it above the sample mold and presses the upper mold, and then the second screw tightening structure 1035 loosens the lower mold screws, thus separating the upper and lower molds. Then, the second and third-axis gripping structure 1037 pushes the upper mold to the sample demolding position of the demolding structure 1032. After the sample is demolded, the second and third-axis robot grips the sample and places it at the marking structure 1033 for marking. After marking, the second and third-axis gripping structure 1037 grips the sample to the demolding sample transfer structure 1036 and transfers it to the test island 2 station. At the same time, the second and third-axis robot grips the lower mold to the lower mold direction adjustment structure 1038 for direction adjustment. Then, the second and third-axis gripping structure 1037 grips the upper mold and the lower mold to the cleaning station for cleaning.

[0046] Immediately after demolding the cement sample from the mold, it is marked to record the sample's information. This facilitates manual inspection in case of anomalies or routine random checks. The marked information is not used for traceability of the cement sample because it is easily rubbed off during water curing. It is only for random checks because the engraved information is easier for humans to read visually than QR code information.

[0047] In one embodiment, the sample preparation island 1 further includes a standard sand bag cutting mechanism 108. The standard sand bag cutting mechanism 108 includes a standard sand hopper 1081, a forklift loading structure 1082 located below the standard sand hopper 1081, a suction cup shaking structure 1083 located on one side of the standard sand hopper 1081, and a bag cutting structure 1084. A weighing sensor is provided below the standard sand hopper 1081, and a vibrator is provided below the bag cutting structure 1084. The suction cup shaking structure 1083 is adapted to pick up the standard sand bags in the standard sand hopper 1081, and the bag cutting structure 1084 is adapted to cut the standard sand bags and transport them to the standard sand bowl.

[0048] refer to Figure 8The standard sand bag cutting mechanism 108 also includes a sixth frame plate 1085, which serves as the outer frame of the machine and provides an operating platform for various structures on the machine. The forklift loading structure 1082 is a multi-tool compatible loading structure, which can accommodate standard sand bags and sample buckets 4, as well as waste bag boxes and waste bins. When the first robot arm 101 grabs the standard sand bag from the forklift loading structure 1082 and places it at the corresponding position in the standard sand bin 1081, the weighing sensor below the standard sand bin 1081 weighs the remaining standard sand bag at any time. The suction cup shaking structure 1083 transfers the sand bag to the standard sand bin 1081, and the bag cutting structure 1084 cuts the standard sand bag. After the bag is cut, the standard sand in the standard sand bag is fed into the standard sand bowl through the feeding sheet metal of the bag cutting structure 1084. The vibrator below the feeding sheet metal vibrates and sends the fallen standard sand into the standard sand bowl as well. After the bag is cut, the suction cup shaking structure 1083 carries the standard sand bag upward a certain distance and shakes it to shake the standard sand in the standard sand bag into the standard sand bowl.

[0049] The weighing sensor continuously weighs the standard sand in the standard sand hopper 1081 to determine the descent depth of the suction cup shaking structure 1083, facilitating the retrieval of the standard sand bag; the vibrator is used to send all the standard sand that falls onto the bag cutting structure 1084 into the standard sand bowl; the suction cup shaking structure 1083 is used to also transport all the standard sand in the standard sand bag into the standard sand bowl, thereby reducing the waste of standard sand and saving costs.

[0050] In one embodiment, the standard sand cutting bag mechanism 108 further includes a waste bag box structure 1086 and a standard sand weighing structure 1087. The standard sand weighing structure 1087 is signal-connected to the suction cup shaking structure 1083 to place the standard sand waste bag into the waste bag box structure 1086.

[0051] When all the standard sand flows into the standard sand bowl, the electronic scale in the standard sand weighing structure 1087 sends a feedback signal to the PLC. At this time, the PLC controls the suction cup shaking structure 1083 to put the standard sand waste bag into the waste bag box structure 1086. When the standard sand bags in the standard sand bin 1081 are used up, the first robot arm 101 grabs the standard sand bag to the forklift loading structure 1082, and the forklift loading structure 1082 sends the standard sand bag back into the standard sand bin 1081. Similarly, when the number of waste bag boxes in the waste bag box structure reaches a certain value, the first robot arm 101 picks up the waste bag box and places it at the corresponding position of the forklift loading structure 1082 and sends it out.

[0052] Once all the standard sand in the sandbag is fed into the standard sand bowl, the waste standard sand bag is promptly recycled, further reducing costs.

[0053] In one embodiment, the test island 2 further includes a sample exchange mechanism 204 and a sample draining mechanism 205 located on one side of the water curing box inlet and outlet exchange mechanism 202. The sample exchange mechanism is adapted to place the first water curing box 6 after it has been cleaned and scanned, and the sample draining mechanism 205 is adapted to place the cement sample after water curing and scanning, and drain it.

[0054] refer to Figure 6 Test island 2 also includes a waste sample conveying mechanism 206. A second robotic arm 201 picks up the cleaned first water-curing box 6 from the water-curing box inlet / outlet exchange mechanism 202, scans it, and places it at the sample exchange mechanism 204. Then, the second robotic arm 201 picks up the sample from sample preparation island 1 and places it into the scanned first water-curing box 6. The second robotic arm 201 then picks up the first water-curing box 6 containing the water sample to be collected and places it at the corresponding position in the water-curing box inlet / outlet exchange mechanism 202. Then, a third robotic arm 301 picks it up and places it into the water-curing tank 305 for water curing. The second robotic arm 201 picks up the cured first water-curing box 6 from the water-curing box inlet / outlet exchange mechanism 202, scans it, and places it on the sample draining mechanism 205. After passing through a quick-change gripper, the second robotic arm 201 picks up the sample and drains it using a brush structure. After draining, it is placed in the sample bending and compressive strength mechanism 203 for bending and compressive strength testing. After the test is completed, the waste cement blocks enter the waste sample conveying mechanism 206. When the waste cement blocks in the waste sample conveying mechanism 206 reach a certain quantity, they are sent out. After the samples in the first water curing box 6 are all picked up, the second robotic arm 201 quickly changes its gripper, picks up the first water curing box 6 and places it in the corresponding position of the water curing box inlet and outlet exchange mechanism 202, and transports it to the cleaning position. After cleaning, the first water curing box 6 is picked up, scanned, and placed on the sample exchange mechanism 204, waiting for the next sample loading.

[0055] The cement sample is placed in the first water curing box 6 after it is cleaned and drained, which avoids the contamination of the cement sample by impurities in the first water curing box 6 and ensures the accuracy of subsequent testing.

[0056] In one embodiment, the water-growing island 3 further includes a second water-growing box cleaning and exchange mechanism 303, a water-growing box cleaning mechanism 304 and a water-growing tank 305 disposed on one side of the second water-growing box cleaning and exchange mechanism 303. The water-growing tank 305 is adapted to place the second water-growing box 302. The second water-growing box cleaning and exchange mechanism 303 is adapted to place the second water-growing box 302 to be cleaned and the second water-growing box 302 after cleaning. The water-growing box cleaning mechanism 304 is adapted to clean the first water-growing box 6 and the second water-growing box 302 to be cleaned.

[0057] refer to Figure 7The hydroponic island 3 also includes a second hydroponic box water filling mechanism 306. A third robotic arm 301 picks up the first hydroponic box 6 to be hydroponically treated from the hydroponic box inlet / outlet exchange mechanism 202, scans the code, and places it into the second hydroponic box 302 in the hydroponic tank 305. The hydroponic tank 305 has water level detection, automatic water filling, and water heating functions to ensure hydroponic conditions. Then, the third robotic arm 301 picks up the first hydroponic box 6 to be cleaned and places it in the hydroponic box cleaning mechanism 304 for cleaning, and then places the cleaned first hydroponic box 6 back into the hydroponic box inlet / outlet exchange mechanism 202. Then, the third robotic arm 301 grabs the second water-maintenance box 302 to be cleaned and moves it to the second water-maintenance box exchange mechanism. After the second robotic arm 201 quickly changes its gripper, the wastewater in the second water-maintenance box 302 is poured into the wastewater outlet of the water filling structure of the second water-maintenance box. Then, the second water-maintenance box 302 is placed into the water-maintenance box cleaning structure for cleaning and drying. The third robotic arm 301 grabs the second water-maintenance box 302 and moves it to the second water-maintenance box cleaning exchange mechanism 303. The cleaned second water-maintenance box 302 is scanned and placed into the water-maintenance tank 305. The scanned first water-maintenance box 6 to be water-maintenance is placed into the corresponding second water-maintenance box 302, thus realizing the information binding between the second water-maintenance box 302 and the first water-maintenance box 6.

[0058] The second water-growing box cleaning and exchange mechanism 303 serves as a transfer station for the second water-growing box 302 to be cleaned and after cleaning, making it easy to operate. The water-growing tank 305 is used to centrally place the second water-growing box 302, making the entire device structure more compact.

[0059] In one embodiment, the sample preparation island 1 further includes a high-pressure cleaning mechanism 109 for mold testing. The high-pressure cleaning mechanism 109 includes a high-pressure cleaning tank 1091, a high-pressure cleaning positioning and transfer structure 1092 disposed in the high-pressure cleaning tank 1091, and a cover 1093 connected to the high-pressure cleaning tank 1091 for opening and closing, and / or The sample island 1 also includes a sample barrel test mold buffer mechanism 110, which includes a test mold buffer frame 1101, a sample barrel buffer structure 1102 located on one side of the test mold buffer frame 1101, and a sample barrel temporary buffer frame 1103 located on one side of the sample barrel buffer structure 1102.

[0060] refer to Figure 9The high-pressure cleaning mechanism 109 also includes a high-pressure cleaning support frame 1094 and a high-pressure system 1095 located below the high-pressure cleaning support frame 1094. The high-pressure cleaning support frame 1094 serves as a machine support, providing an operating platform for each structure. The high-pressure system 1095 provides a high-pressure water source for high-pressure cleaning. After the upper mold horizontal plate, vertical plate, and lower mold to be cleaned are placed in the placement position of the high-pressure cleaning positioning and transfer structure 1092, the high-pressure cleaning positioning and transfer structure 1092 transfers them to the cleaning position. The cover 1093 closes the high-pressure cleaning tank 1091, making the cleaning a relatively enclosed space. Then, the water spray head and air spray head of the high-pressure cleaning tank 1091 begin to clean and dry the upper mold horizontal plate, vertical plate, and lower mold to be cleaned. After cleaning, the high-pressure cleaning positioning and transfer structure 1092 transfers them to the cleaning completion grabbing position, where the next machine will grab them.

[0061] refer to Figure 10 After the trial mold is closed, the first robotic arm 101 picks up the trial mold from the mold closing and oiling mechanism 107 and places it in the corresponding position on the trial mold buffer rack 1101. Simultaneously, if the stirring and cleaning vibration mechanism 104 transmits a signal requiring the trial mold to be placed on the vibration table structure 1044, the first robotic arm 101 picks up the trial mold and places it at the oil spraying structure 1078 for oil spraying. After oil spraying is completed, the first robotic arm 101 picks up the trial mold and places it on the vibration table structure 1044. (Reference) Figure 11 The sample barrel test mold buffer mechanism 110 does not have a sample barrel temporary buffer rack 1103. The sample barrel buffer structure 1102 is used to store sample barrels. The first layer of the test mold buffer rack 1101 is the test mold buffer after scraping and checking for leakage of the test mold. The rest are the test mold buffers after cleaning and air drying.

[0062] After the high-pressure cleaning positioning and transfer structure 1092 transports the test mold to the cleaning station, the cover 1093 closes the opening of the high-pressure cleaning tank 1091, thus forming a closed cleaning space to prevent cleaning water from splashing. The test mold buffer rack 1101 is used to place the test mold to be processed, and the sample barrel buffer structure 1102 is used to place the sample barrel. When it is necessary to grab the sample barrel inside the sample barrel buffer structure 1102, the outer sample barrel can be placed on the sample barrel temporary buffer rack 1103 for buffering.

[0063] In one embodiment, the sample preparation island 1 further includes a lid-opening and material-retrieving mechanism 111. The lid-opening and material-retrieving mechanism 111 includes a bucket clamping structure 1111 and a lid-opening and material-grabbing structure 1112 and a direct vibration feeding structure 1113 disposed on one side of the bucket clamping structure 1111. The direct vibration feeding structure 1113 feeds the powdered cement into the cement bowl and weighs it.

[0064] refer to Figure 12The opening and material handling mechanism 111 also includes a seventh frame plate 1114 and a weighing waste collection structure 1115 mounted on the first frame plate 1041. The first frame plate 1041 serves as the outer frame of the machine, providing an operating platform for various structures on the machine. When the sample barrel is placed at the clamping structure 1111, the structure clamps and positions the sample barrel. Then, the opening and material handling structure 1112 opens and handles the sample barrel, placing the powdered cement into the direct vibration feeding structure 1113. The direct vibration feeding structure 1113 feeds the powdered cement into the cement bowl of the weighing waste collection structure 1115. When a certain weight is reached, the electronic scale sends a feedback signal, the direct vibration feeding structure 1113 stops feeding, and the weighing waste collection structure 1115 transfers the waste barrel to the outlet of the direct vibration feeding structure 1113, and sends the excess powdered cement into the waste barrel. Then the first robotic arm 101 grabs the cement bowl containing powdered cement and moves it to the next machine.

[0065] The clamping structure 1111 is used to clamp and position the sample barrel, and the opening and material grabbing structure 1112 is used to open the lid of the sample barrel and pick up the material, thereby realizing the automation of material picking.

[0066] The specific working process of the cement mortar strength testing system provided by this invention is as follows: First, multiple base plates are assembled, and the sample preparation island, testing island, and water-raising island are placed on the assembled base plates in sequence. The number of base plates can be flexibly adjusted according to the size of the sample preparation island, testing island, and water-raising island equipment, and they are easy to assemble and disassemble.

[0067] Then, the first robotic arm 101 grabs the sample bucket, scans the code, and puts it into the opening and material handling mechanism 111. The opening and material handling mechanism 111 sends the powdered cement in the sample bucket into the cement bowl. The first robotic arm 101 grabs the cement bowl and pours the powdered cement into the mixing pot of the mixing and cleaning vibration mechanism 104. A certain amount of water has been added to the mixing pot beforehand.

[0068] The first robotic arm 101 grabs the standard sand bag and places it onto the standard sand bag cutting mechanism 108. The mechanism cuts the standard sand bag and fills it with all the standard sand into the standard sand bowl. The first robotic arm 101 then grabs the standard sand bowl and pours the standard sand into the mixer 1047.

[0069] The two-shaft structure in the mixing and cleaning vibration mechanism 104 carries a mixing pot, which is first filled with a certain amount of water, followed by the addition of powdered cement. The two-shaft structure carries the mixing pot to the mixing position of the mixer 1047, where sand is added and mixed to form mortar. Simultaneously, the first robotic arm 101 grabs the mold in the sample bucket mold buffer mechanism 110 and sprays it with oil in the mold closing and oiling mechanism 107. After oiling, the first robotic arm 101 grabs the mold onto the vibration table structure 1044 and grabs the funnel from the funnel cleaning mechanism 106, placing it on the mold. Then, the mixed mortar is poured into the mold in the vibration table structure 1044. The first robotic arm 101 grabs the funnel and cleans it in the funnel cleaning mechanism 106, and then grabs the mold and scrapes it in the mold leveling mechanism 105 to level it into a standard cuboid block.

[0070] After the mold is leveled in the mold leveling mechanism 105, the first robot arm 101 picks up the mold and moves it to the testing station in the wet curing mechanism 102 to check for grout leakage. If there is no leakage, the first robot arm 101 picks up the mold, scans the code, and places it in the wet curing position of the wet curing mechanism 102 for wet curing. After the funnel is rinsed and dried in the funnel cleaning mechanism 106, the first robot arm 101 picks up the funnel and moves it above the mold on the vibration table structure 1044 of the mixing and cleaning vibration mechanism 104. At the same time, the first robot arm 101 picks up the wet-cured mold, scans the code, and places it in the cement sample demolding mechanism 103 for demolding and sampling, and then transfers the sample to the test island 2. At the same time, the cement sample demolding mechanism 103 puts the disassembled upper mold horizontal plate, vertical plate and lower mold into the high pressure cleaning mechanism 109 for high pressure cleaning to clean the adhering mortar cement blocks. If leakage is detected, the first robot arm 101 grabs the mold and places it at the leakage mold placement position of the sample barrel mold buffer mechanism 110 for subsequent manual processing.

[0071] After the upper mold horizontal plate, vertical plate and lower mold are cleaned, the first three-axis gripping structure 1074 of the mold closing and oiling mechanism 107 grips the upper mold horizontal plate, vertical plate and lower mold from the high pressure cleaning mechanism 109 and puts them into the oiling station for oiling. After the mold is closed, the first robot arm 101 grips the closed mold and puts it into the mold buffer position of the sample barrel mold buffer mechanism 110.

[0072] After demolding, the sample is transferred to test island 2. The second robot 201 picks up the sample and places it into the scanned first curing box 6. Then, the second robot 201 picks up the first curing box 6 containing the sample and moves it to the corresponding position in the curing box in / out exchange mechanism 202, and transports it to curing island 3. The second robot 201 then picks up the first curing box 6 containing the cured sample, scans it, and places it in the sample drying structure for drying. After drying, the second robot 201 picks up the sample and places it in the sample bending and compressive strength structure for testing. The waste residue from the test flows into the waste sample conveying structure. Once a certain amount of waste residue is present in the waste sample conveying structure, it is automatically transferred. After the sample in the sample drying structure has been tested, the second robot 201 picks up the first curing box 6 to be cleaned and moves it to the corresponding position. The third robot 301 then picks up the first curing box 6 to be cleaned and moves it to the cleaning station for cleaning. The second robot 201 picks up the cleaned first curing box 6, scans it, and places it in the corresponding position in the sample exchange mechanism 204.

[0073] When the first water conditioning box 6 containing the water conditioning box to be water-conditioned is placed in the corresponding position of the water conditioning box inlet / outlet exchange mechanism 202, the third robotic arm 301 picks up the cleaned second water conditioning box 302, scans its code, adds a certain amount of clean water to the second water conditioning box water filling mechanism 306, and then places it into the water conditioning tank 305. Then, the third robotic arm 301 picks up the first water conditioning box 6 containing the water conditioning box to be water-conditioned, scans its code, and places it into the scanned second water conditioning box 302, thus binding the relationship between the first water conditioning box 6 and the second water conditioning box 302. The third robotic arm 301 picks up the first water-cured box 6 from the second water-cured box 302 in the water-curing tank 305 and places it in the corresponding position of the water-cured box inlet / outlet exchange mechanism 202. Simultaneously, it picks up the second water-cured box 302 and places it into the second water-cured box cleaning and exchange mechanism 303. The third robotic arm 301, using quick-change grippers, picks up the second water-cured box 302 and pours the wastewater into the wastewater tank of the second water-cured box water filling mechanism 306. Then, it places the second water-cured box 302 to be cleaned in the water-cured box cleaning mechanism 304 for cleaning. After cleaning, the second water-cured box 302 is scanned, and a certain amount of water is added to the second water-cured box water filling mechanism 306 before being placed back into the water-curing tank 305. After quick-change grippers, the third robotic arm 301 picks up the first water-cured box 6 to be cleaned from the water-cured box inlet / outlet exchange mechanism 202 and places it in the water-cured box cleaning mechanism 304 for cleaning. After cleaning, it is placed in the corresponding position of the water-cured box inlet / outlet exchange mechanism 202.

[0074] The cement mortar strength testing system provided by this invention can accurately record the incoming cement powder, the water curing of test blocks, and the test results. It also automates operations such as leveling, oiling, demolding, mold closing, and mold cleaning, further improving the accuracy of cement mortar strength testing results and the consistency of sample preparation.

[0075] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
