Description

Technical Field

[0001] This invention belongs to the field of construction machinery automation technology, specifically relating to an integrated machine and method for testing the curing and compressive strength of concrete test blocks. Background Technology

[0002] With the continuous expansion of infrastructure construction, concrete, as a key building material, directly affects the durability and safety of engineering structures. In the production and application of concrete, the curing and compressive strength testing of concrete test blocks are crucial steps in assessing concrete quality and ensuring project quality.

[0003] Traditionally, the curing and compressive strength testing of concrete specimens are usually carried out as two separate processes. The curing room and the compressive strength testing room are often set up separately. After the concrete specimens are cured, they need to be manually transported to the testing room for compressive strength testing. This process is not only time-consuming and labor-intensive, but also prone to damage to the specimens during transportation, introducing human error. Summary of the Invention

[0004] In the existing technology, the curing and compressive strength testing of concrete test blocks are usually carried out in two separate processes. After the concrete test blocks are cured, they need to be manually transported to the testing room for compressive strength testing. This process is not only time-consuming and labor-intensive, but also prone to damage to the test blocks during transportation, introducing human error. The present invention provides an integrated machine and testing method for curing and compressive strength testing of concrete test blocks to solve the above-mentioned technical problems.

[0005] In a first aspect, the present invention provides an integrated machine for curing and testing the compressive strength of concrete test blocks, comprising: The chamber has internal partitions with electric doors that divide it into a curing room and a compressive strength testing room. The curing room provides a constant temperature and humidity environment for curing, while the compressive strength testing room is used to test the compressive strength of the cured concrete test blocks. Anti-tilt track, installed at the top of the enclosure; The load-bearing floor rail is installed at the bottom of the enclosure and is symmetrically arranged with the anti-tilting ceiling rail; The concrete test block transport belt conveyor is set at one end in the compressive strength testing chamber and extends to the outside of the box body. It is used to transport the demolded concrete test blocks to the compressive strength testing chamber. The concrete test block transport belt conveyor is equipped with an inbound temporary storage station and an outbound temporary storage station on one side. The pressure testing machine, installed in the pressure testing chamber, is used to test the pressure of cured concrete test blocks. A six-axis robot is installed on one side of the concrete test block transfer conveyor belt. It is used to transfer concrete test blocks on the concrete test block transfer conveyor belt to the pallet at the inbound temporary storage station, and to transfer concrete test blocks at the outbound temporary storage station to the pressure testing machine. The three-dimensional curing rack is set on both sides of the load-bearing floor rail in the curing room and is used to store trays containing concrete test blocks in layers. The palletizer is set between the anti-tilting overhead rail and the load-bearing ground rail, and can move along the anti-tilting overhead rail and the load-bearing ground rail. It is used to remove the pallet carrying the concrete test block from the three-dimensional curing rack in the curing room or to put the pallet carrying the concrete test block into the three-dimensional curing rack to complete the entry and exit operation of the concrete test block. The PLC connects to the electric gate, concrete test block transport belt conveyor, pressure testing machine, six-axis robot, and palletizer to control the electric gate, concrete test block transport belt conveyor, pressure testing machine, six-axis robot, and palletizer to complete the curing and compressive strength testing of concrete test blocks.

[0006] Further improvements to this technical solution include: the three-dimensional curing rack is configured with several layers of curing racks, each layer of curing rack is configured with several tray placement positions, each tray placement position is assigned a number, and a pressure sensor is installed on each tray placement position. The pressure sensor and the tray placement position number are associated and stored in a database.

[0007] A further improvement to this technical solution is that the pressure testing machine is a concrete test block pressure machine of model JSYL-3000.

[0008] Further improvements to this technical solution include the installation of a waste recycling device in the pressure testing chamber to recover waste generated after pressure testing.

[0009] A further improvement to this technical solution is that a touch screen is installed on the outside of the enclosure, and control buttons are provided on the touch screen for displaying the equipment's operating status and operation control.

[0010] A further improvement to this technical solution is that a scanner is installed above the concrete test block transport belt conveyor. The scanner is used to scan the QR code markings on the concrete test blocks, and the QR code markings are used to record information about the concrete test blocks.

[0011] A further improvement to this technical solution is that limit switches are installed on the running paths of the palletizer and the six-axis robot to prevent the palletizer and the six-axis robot from running beyond the predetermined range.

[0012] Secondly, the present invention provides a method for testing the curing compressive strength of concrete test blocks, applicable to the integrated machine for testing the curing compressive strength of concrete test blocks as described in any of the above claims, the method comprising: S1. Specimen block transfer: The demolded concrete specimen blocks are sequentially transported to the temporary storage station in the compressive strength testing room via a concrete specimen block transfer belt conveyor and a six-axis robot. S2, Test block storage: The palletizer moves along the anti-tilting overhead rail and the load-bearing ground rail to transport the pallet carrying the concrete test blocks on the temporary storage station to the three-dimensional curing rack in the curing room for curing. S3. Curing process: The temperature and humidity control device in the curing room maintains a constant temperature and humidity environment in the curing room based on the monitoring results of the temperature and humidity sensor. At the same time, the pressure sensor on the three-dimensional curing rack monitors the placement status of the tray in real time. S4, Test block outbound: The palletizer moves the cured pallet from the three-dimensional curing rack to the outbound temporary storage station in the compression testing room; S5. Test block testing: The six-axis robot transports the concrete test blocks from the outgoing temporary storage station to the pressure testing machine for compressive strength testing. After the test is completed, the waste recycling device recycles the generated waste. S6. Data Management: The operating status and operation control of the all-in-one machine are displayed on the touch screen, while the curing and pressure test data of concrete test blocks are recorded and electronic reports are generated.

[0013] Further improvements to this technical solution include step S1, which includes: Sensor SQ7, installed at the inlet of the concrete test block transfer conveyor, detects whether concrete test blocks are being transferred to the concrete test block transfer conveyor. If so, the PLC controls the operation of the concrete test block transfer conveyor belt, and at the same time starts the scanner installed above the concrete test block transfer conveyor belt to scan the QR code mark set on the concrete test block, obtain the information of the concrete test block, and send the obtained concrete test block information to the PLC. The PLC sends control commands to the palletizer and the six-axis robot based on the information received from the concrete test blocks. The palletizer and the six-axis robot work together to complete the curing and compressive strength testing of the concrete test blocks according to the received control instructions.

[0014] Further improvements to this technical solution include providing information on the concrete test blocks, such as the block number, demolding time, curing age, strength grade, block size, curing conditions, testing requirements, and the target tray placement position number on the curing rack.

[0015] The beneficial effects of this invention are as follows: Traditionally, the curing and compressive strength testing of concrete test blocks are two separate processes. After curing, the test blocks need to be manually transported from the curing room to the testing room. This process is not only time-consuming and labor-intensive, but also prone to damage during transport, introducing human error. This invention, through an integrated design, combines the curing room and the compressive strength testing room into a single enclosure. Automated equipment is used to complete the transport and testing of the test blocks, significantly improving work efficiency, reducing human intervention, and lowering the risk of damage during transport.

[0016] This invention utilizes a six-axis robot and a palletizer to automate the handling of test blocks. A conveyor belt transports the demolded test blocks automatically into the curing chamber, and after curing, they are automatically transferred to the compressive strength testing chamber for analysis. The entire process requires no manual intervention, reducing errors caused by human operation and improving the accuracy and reliability of the test results.

[0017] This invention displays the device's operating status and control via a touchscreen, while simultaneously recording curing and pressure testing data for concrete test blocks and generating electronic reports. This intelligent data management method not only improves the accuracy and traceability of data recording but also facilitates real-time monitoring and analysis of concrete quality by engineering managers, thereby enhancing the overall level of project quality management.

[0018] The pressure testing chamber is equipped with a waste recycling device to recover waste generated after pressure testing. This design not only reduces environmental pollution from waste but also improves the environmental performance of the equipment, meeting the requirements of green and low-carbon development.

[0019] An air curtain machine is installed above the electric door. When the electric door is opened, the air curtain machine is activated to form an air barrier, effectively preventing the external environment from affecting the internal environment of the curing room and the pressure testing room, and further ensuring the stability of the curing and testing environment.

[0020] The three-dimensional curing rack is equipped with several layers, each layer containing several pallet placement positions, each assigned a unique number. Simultaneously, a pressure sensor is installed at each pallet placement position, establishing a link between the pressure sensor and the pallet placement position number, which is then stored in a database. This design enables precise management of the location and status of each pallet, facilitating traceability and management, and further enhancing the equipment's intelligence level.

Detailed Implementation

[0034] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] like Figure 1 As shown, this invention provides an integrated machine for curing and testing the compressive strength of concrete test blocks, comprising: The box 110 has an internal partition 111, and an electric door 112 is installed on the partition 111. The partition 111 and the electric door 112 divide the box 110 into a curing room and a compressive strength testing room. The curing room is used to provide a constant temperature and humidity curing environment, and the compressive strength testing room is used to perform compressive strength testing on the cured concrete test blocks. Anti-tilt track 121 is installed on the top of housing 110; The load-bearing ground rail 122 is installed at the bottom of the box 110 and is symmetrically arranged with the anti-tilting ceiling rail 121. A concrete test block transport belt conveyor 130 is installed at one end in the compressive strength testing chamber and extends to the outside of the box 110 at the other end. It is used to transport the demolded concrete test blocks to the compressive strength testing chamber. A temporary storage station 150 for entering the warehouse and a temporary storage station 160 for exiting the warehouse are configured on one side of the concrete test block transport belt conveyor 130. The temporary storage station 150 for entering the warehouse is used to temporarily store the demolded concrete test blocks. The temporary storage station 160 for exiting the warehouse is used to temporarily store the pallet 181 carrying the concrete test blocks that is transported out of the curing chamber. The pressure testing machine 140 is installed in the pressure testing chamber and is used to test the pressure of cured concrete test blocks. A six-axis robot 170 is set on one side of the concrete test block transfer conveyor 130. It is used to transfer concrete test blocks on the concrete test block transfer conveyor 130 to the pallet 181 on the warehouse temporary storage station 150, and to transfer concrete test blocks on the warehouse temporary storage station 160 to the pressure testing machine 140. A three-dimensional curing rack 180 is set on both sides of the load-bearing ground rail 122 in the curing room and is used to store trays 181 that carry concrete test blocks in layers. The palletizer 123 is set between the anti-tilting overhead rail 121 and the load-bearing ground rail 122 and can move along the anti-tilting overhead rail 121 and the load-bearing ground rail 122. It is used to remove the pallet 181 carrying concrete test blocks from the three-dimensional curing rack 180 or to put the pallet 181 carrying concrete test blocks into the three-dimensional curing rack 180 to complete the entry and exit operation of concrete test blocks. The PLC is connected to the electric gate 112, the concrete test block transfer belt conveyor 130, the six-axis robot 170, the pressure testing machine 140, and the palletizer 123. It is used to control the electric gate 112, the concrete test block transfer belt conveyor 130, the six-axis robot 170, the pressure testing machine 140, and the palletizer 123 to complete the curing and compressive strength testing of the concrete test blocks. That is, it controls the integrated curing and compressive strength testing machine to perform curing and pressure testing on the concrete test blocks. The power module is used to supply power to the entire integrated maintenance and pressure testing machine.

[0037] Specifically, the enclosure 110 is made of high-strength metal materials, such as stainless steel or aluminum alloy, ensuring a stable structure and good rust resistance. The partition 111 is also made of metal, with an insulation layer, such as polyurethane foam board, on its surface to enhance the temperature control of the curing chamber. The electric door 112 is an automatic sensor-operated door equipped with an infrared sensor that automatically opens and closes when an object is detected approaching. The door has excellent sealing performance, using rubber sealing strips to prevent temperature and humidity loss from the curing chamber. The partition 111 divides the enclosure 110 in the middle, with a space ratio of 3:2 between the curing chamber and the pressure testing chamber.

[0038] Both the anti-tilt overhead rail 121 and the load-bearing ground rail 122 are made of high-quality I-beams and are securely installed at the top and bottom of the housing 110 using high-strength bolts. The surfaces of the overhead and ground rails undergo high-precision machining to ensure flatness and straightness, guaranteeing smooth movement of subsequent equipment. The automatic palletizer 123 is equipped with an infrared positioning sensor to identify the position of the pallet 181. Furthermore, to improve operational reliability, limit switches are installed along the operating paths of the palletizer 123 and the six-axis robot 170 to prevent them from exceeding predetermined ranges and to prevent derailment.

[0039] The concrete test block transport belt conveyor 130 includes a drive motor, a conveyor belt, and a frame. The drive motor drives the conveyor belt, which carries and transports the concrete test blocks. The frame supports the conveyor belt. The frame is welded from steel to ensure structural stability. The belt is made of wear-resistant and corrosion-resistant rubber, and its width is determined according to the size of the concrete test blocks to ensure stable placement. The drive motor of the transport belt conveyor uses a combination of a motor and a reducer, with the motor speed controlled by a frequency converter to achieve stepless speed regulation to adapt to different transport needs. Photoelectric sensors are installed at the beginning and end of the belt conveyor to detect the position of the test blocks and enable automatic start / stop functionality.

[0040] The pressure testing machine 140 uses a JSYL-3000 concrete block pressure press. The pressure testing chamber is also equipped with a waste recycling device (featuring a waste transfer belt and a waste bin located at the end of the belt furthest from the pressure testing machine 140) to collect waste generated after pressure testing. The pressure testing machine 140 also includes an automatic cleaning device, comprising a rotating brush and an air blowing mechanism. This device cleans the testing platform of the pressure testing machine 140 after block testing to ensure the accuracy of subsequent tests and removes waste generated after pressure testing to the waste recycling device.

[0041] Both the inbound temporary storage station 150 and the outbound temporary storage station 160 consist of metal supports and pallets 181. The supports are height-adjustable to accommodate pallets 181 of varying heights. Pallets 181 are made of high-strength plastic with a degree of elasticity to prevent damage to the concrete test blocks, and their surface has anti-slip textures to increase the stability of the test blocks. Protective railings are installed around the temporary storage stations to prevent accidental drops of the test blocks. Both inbound and outbound temporary storage stations 150 and 160 are equipped with sensors to detect the arrival of the test blocks and transmit the detection signals to the PLC.

[0042] The six-axis robot 170 utilizes an industrial robot with high load capacity and high-precision positioning performance. Its control system can precisely plan motion trajectories to achieve fast and stable pick-and-place actions. The robot's end effector is designed as a specialized gripper based on the shape and size of the concrete test block, using pneumatic or electric drive to firmly grasp the test block without damaging its surface. Simultaneously, a safety light curtain is installed in the robot's working area; if a person or object enters the danger zone, the robot immediately stops working to ensure personnel safety. The six-axis robot 170 is equipped with a vision recognition system to identify the position and state of the concrete test block for precise gripping and placement.

[0043] The 180-layer curing rack utilizes a steel frame structure, assembled through welding and bolting to ensure structural robustness. The number of layers is rationally designed based on the height of the curing chamber, with sufficient spacing between each layer to accommodate trays 181 carrying concrete test blocks. Rolling guides are installed on each layer for easy loading and unloading of trays 181. The surface of the curing rack undergoes rust-proofing treatment, such as spraying with anti-rust paint. The 180-layer curing rack comprises several layers, each with several tray placement positions. Each tray placement position is assigned a number, and a pressure sensor is installed at each position. A correlation is established between the pressure sensor and the tray placement position number, and this information is stored in a database.

[0044] The main structure of the palletizer 123 consists of a frame, a traveling mechanism, a lifting mechanism, and a gripping mechanism. The frame is made of high-strength steel to ensure overall stability. The traveling mechanism uses a motor-driven roller to move along the anti-tilt top rail 121 and the load-bearing ground rail 122, achieving horizontal position adjustment. The lifting mechanism uses a screw-nut drive or chain drive, driven by a motor, and can precisely control the lifting height of the gripping mechanism. The gripping mechanism is compatible with the pallets 181 on the three-dimensional curing rack 180, reliably gripping and placing the pallets 181. The gripping mechanism includes vacuum suction cups or mechanical grippers. The palletizer 123 is equipped with an intelligent control system that can automatically complete the inbound and outbound operations of the pallets 181 according to a preset program.

[0045] The PLC connects to an external server via an Ethernet interface to upload curing and testing data of the test blocks, facilitating remote monitoring and data analysis. The touchscreen's network port is connected to the server via a switch. The PLC is configured with functions such as test block entry and exit registration, demolding time query, outbound time query, curing period (i.e., curing duration), and reminders for due dates for testing.

[0046] An emergency stop button is installed on the outside of the enclosure 110. The emergency stop button is used to stop the operation of all equipment in an emergency to ensure the safety of equipment and personnel.

[0047] In addition, the curing room is equipped with temperature and humidity sensors and a temperature and humidity control device. The temperature and humidity sensors are used to monitor the temperature and humidity inside the curing room in real time, and the temperature and humidity control device is used to adjust the temperature and humidity inside the curing room according to the monitoring results of the temperature and humidity sensors. Figure 2 and Figure 3 As shown, the temperature and humidity control device includes a temperature and humidity controller (or temperature and humidity control box), a temperature and humidity sensor connected to the input terminal of the temperature and humidity controller, and a heater, a cooler, and a humidifier connected to the output terminal of the temperature and humidity controller. The temperature and humidity control device also includes contactors KM1, KM2, and KM3, a start button SB1, a heating button SB2, a cooling button SB3, and a humidification button SB4. The heater is connected to the temperature and humidity controller via contactor KM1 and heating button SB2, the cooler is connected to the temperature and humidity controller via contactor KM2 and cooling button SB3, and the humidifier is connected to the temperature and humidity controller via contactor KM3 and humidification button SB4. The temperature and humidity controller is connected to an external power source via start button SB1.

[0048] The temperature and humidity control system in the curing chamber automatically adjusts the temperature and humidity based on real-time monitoring results from temperature and humidity sensors, ensuring the stability and consistency of the curing environment. Pressure sensors on the three-dimensional curing rack monitor the placement of the trays in real time, further guaranteeing the stability of the test blocks during the curing process. This precise environmental control effectively promotes the uniform development of the concrete test block strength and improves the accuracy of test results.

[0049] Furthermore, the integrated maintenance and pressure testing machine also includes an air curtain machine, which is installed on the upper housing 110 above the electric door 112. When the electric door 112 is opened, the air curtain machine is activated, forming an air barrier to effectively prevent the external environment from affecting the internal environment of the maintenance room and the pressure testing room, thus further ensuring the stability of the maintenance and testing environment.

[0050] In addition, a touchscreen is installed on the outside of the housing 110, with control buttons for displaying equipment operating status and operation control. The touchscreen uses an embedded installation method, with pre-drilled mounting holes on the outside of the housing 110 matching its size. The touchscreen is securely fixed in the mounting holes using clips and bolts, ensuring it will not shake or fall off during equipment operation. The installation location is chosen on the outside of the housing 110 in an area easily visible and operable by the operator. Virtual control buttons are provided on the touchscreen, including a start / stop button, individual control buttons for each functional module (such as the curing chamber, pressure testing machine 140, and conveyor belt), parameter setting buttons (such as setting the curing chamber temperature and humidity, and setting pressure testing parameters), and a fault reset button. The touchscreen can display the real-time operating status of each component, such as the current temperature and humidity of the curing chamber, the working status of the pressure testing machine 140, the operating speed of the conveyor belt, and the positions of the palletizer 123 and the six-axis robot 170. When a fault occurs, the touchscreen will display the corresponding fault code and fault information, facilitating timely troubleshooting by the operator. Meanwhile, operators can control the equipment via touch control buttons, such as adjusting the temperature and humidity parameters of the maintenance room, starting or stopping a certain function module, etc.

[0051] In addition, a scanner is installed above the concrete test block transport conveyor belt 130. This scanner scans the QR code markings on the concrete test blocks, which record information about the blocks. The scanner is mounted on an adjustable bracket above the frame of the conveyor belt 130. The bracket, made of metal, is height and angle adjustable, allowing for flexible adjustment of the scanner's posture based on the position of the QR code markings on the concrete test blocks, ensuring accurate coverage of the path the test blocks travel on the conveyor belt. The scanner is also equipped with a protective housing made of dustproof and waterproof material to prevent dust and moisture generated during conveyor belt operation from affecting its performance. An industrial-grade QR code scanner is used, supporting rapid recognition of QR codes of different sizes and printing methods. It boasts high scanning accuracy and speed, adapting to the conveyor belt's transport speed to ensure rapid scanning as test blocks pass by. The scanner connects to the equipment's control system via a data cable, transmitting the scanned QR code information to the system database in real time.

[0052] Figure 4This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 4 The executing entity can be an integrated machine for curing and testing the compressive strength of concrete test blocks. Depending on different needs, the order of the steps in this flowchart can be changed, and some steps can be omitted.

[0053] like Figure 4 As shown, the method includes: S1. Specimen block transfer: The demolded concrete specimen blocks are sequentially transferred to the temporary storage station 150 in the compressive strength testing room via the concrete specimen block transfer belt conveyor 130 and the six-axis robot 170. S2, Test block storage: The palletizer 123 moves along the anti-tilting overhead rail 121 and the load-bearing ground rail 122 to transport the pallet 181 carrying the concrete test blocks on the temporary storage station 150 to the three-dimensional curing rack 180 in the curing room for curing. S3. Curing process: The temperature and humidity control device in the curing room maintains a constant temperature and humidity environment in the curing room based on the monitoring results of the temperature and humidity sensor. At the same time, the pressure sensor on the three-dimensional curing rack 180 monitors the placement status of the tray 181 in real time. S4, Test block out of warehouse: Palletizer 123 moves the cured pallet 181 from the three-dimensional curing rack 180 to the outbound temporary storage station 160 in the pressure resistance testing room; S5. Test block testing: The six-axis robot 170 transports the concrete test block on the outgoing temporary storage station 160 to the pressure testing machine 140 for compressive strength testing. After the test is completed, the waste recycling device recycles the generated waste. S6. Data Management: The operating status and operation control of the all-in-one machine are displayed on the touch screen, while the curing and pressure test data of concrete test blocks are recorded and electronic reports are generated.

[0054] To facilitate understanding of the present invention, the following description further illustrates the method for testing the curing compressive strength of concrete test blocks provided by the present invention, based on the principle of the method and the process of testing the curing compressive strength of concrete test blocks in the embodiments.

[0055] To achieve automatic control of the integrated maintenance and pressure testing machine, this invention incorporates a limit sensing module in its hardware, such as... Figure 10 As shown, the limit sensing module includes several limit sensors and several inductors, namely SQ1 to SQ20. Each limit sensor and inductor is connected in series with an intermediate relay KAn (n=1,2,...,20). The limit sensors and inductors are all connected to the PLC through the series-connected intermediate relays. Figure 10The "Pallet Detection at Station 1" indicates that a sensor SQ8 (a pressure sensor) is installed at the receiving temporary storage station. When a pallet is present at the receiving temporary storage station, sensor SQ8 sends a trigger signal to the PLC via intermediate relay KA8. The PLC then triggers the execution of subsequent control procedures based on the trigger signal. Similarly, "Pallet Detection at Station 2" indicates that a sensor SQ9 (a pressure sensor) is installed at the outgoing temporary storage station. When a pallet is present at the receiving temporary storage station, sensor SQ9 sends a trigger signal to the PLC via intermediate relay KA9. The PLC then triggers the execution of subsequent control procedures based on the trigger signal. Figure 10 The “conveying thermal protection test” in the text refers to the thermal protection test of the conveyor belt for transporting concrete test blocks. Figure 10 The “backup signal 1” indicates a backup interface used to connect to newly added devices. Figure 10 The terms "protection in place" and "protection in place" correspond to the lifting and lowering limits of the protection motor of the pressure testing machine. Figure 10 The “Upper limit of lifting Z-axis”, “Lower limit of lifting Z-axis”, “Front position of traveling Y-axis”, “Rear position of traveling Y-axis”, “Front position of horizontal X-axis” and “Rear position of horizontal X-axis” are all limit designs corresponding to the palletizer, that is, limit switches set on the running path of the palletizer.

[0056] Step S1 includes: Sensor SQ7, installed at the inlet of concrete block transfer conveyor 130, detects whether concrete blocks are being transferred to concrete block transfer conveyor 130. If so, the PLC controls the concrete test block transfer conveyor belt 130 to run, and at the same time starts the scanner installed on the concrete test block transfer conveyor belt 130 to scan the QR code mark set on the concrete test block, obtain the information of the concrete test block, and send the obtained information of the concrete test block to the PLC. The PLC sends control commands to the palletizer 123 and the six-axis robot 170 based on the information received from the concrete test blocks. The palletizer 123 and the six-axis robot 170 cooperate to complete the curing and compressive strength testing of the concrete test blocks according to the received control instructions.

[0057] Specifically, the information for concrete test blocks includes the block number, demolding time, curing age, strength grade, block size, curing conditions, testing requirements, and the target tray placement position number on the curing rack.

[0058] The sensor SQ7 determines whether the test block has reached the designated position by detecting the physical presence of the test block (such as blocking light or triggering a micro switch); specifically, the sensor SQ7 is an infrared sensor.
