At present, although there are some automated demoulding equipment and molds adapted to them on the market, they still rely on manual transportation of the molds to the demoulding device and coordination with the demoulding device, which can easily cause damage to the test blocks or sticking to the mold, affecting the quality of the test blocks. Summary of the invention

[0017] By adopting the above technical solution, when the membrane box containing the concrete test block is placed on the pallet, the pressure sensor detects the pressure change on the pallet, thereby determining whether there is a membrane box on the pallet. The first control device is connected to the pressure sensor signal, and can record the time the membrane box is stationary on the pallet through its built-in timer. When the membrane box is placed on the pallet, the pressure sensor activates the first control device to start timing and determine whether the concrete test block has stayed on the pallet for a sufficient time. If the membrane box stays for a certain time or exceeds the preset time, the first control device will send a signal to the control center, and the transfer robot will complete the transfer of the stationary membrane box to the demolding device for demolding.

[0023] By adopting the above technical solution, the camera is arranged above the pedestal, and the shooting angle is vertically downward, which is conducive to accurately capturing the position information of the concrete specimen.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] Example 1 The embodiment of the present application discloses a concrete test block mold.

[0029] like Figure 1 and Figure 2As shown, the concrete test block mold includes a membrane box 1, and a pinhole 2 is provided at the bottom wall of the membrane box 1, and the pinhole 2 penetrates the bottom wall of the membrane box 1. After the pinhole 2 is provided on the bottom wall of the membrane box 1, a positioning groove 3 is provided at the end of the pinhole 2 away from the inside of the membrane box 1, and the positioning groove 3 is circular. A plurality of air inlet holes 4 are provided at the inner wall of the positioning groove 3, and a plurality of air outlet holes 5 are provided at the inner wall of the membrane box 1. The air inlet holes 4 correspond to the air outlet holes 5 one by one, and an air path 6 for gas to pass through is formed between the corresponding air inlet holes 4 and the air outlet holes 5. In actual use, the cross-sectional shape of the membrane box 1 can be circular, triangular, rectangular, star-shaped or any other shape. The number of air inlet holes 4, the number and position of air outlet holes 5 can be set according to the cross-sectional shape of the membrane box 1. The material of the box body can be stainless steel, aluminum alloy or polymer material.

[0030] In this embodiment, the cross-sectional shape of the membrane box 1 is rectangular, and the number of the air inlet holes 4 and the air outlet holes 5 are four, and the four air outlet holes 5 are respectively arranged at the center of the four inner side walls of the membrane box 1. The air passage 6 formed between the air inlet holes 4 and the air outlet holes 5 for gas to pass through can inject gas between the concrete block and the inner wall of the membrane box 1, improve the gas circulation efficiency during the demoulding process, and realize the soft ejection between the concrete test block and the side wall in the membrane box 1, thereby reducing the demoulding resistance, so that the test block is evenly stressed during the ejection process using the ejector pin 804, preventing the test block from being broken or damaged due to uneven stress during the ejection process, reducing the possibility of damage to the test block, and improving the demoulding speed. The bottom of the membrane box 1 is provided with a positioning rib 7, which can ensure the precise positioning of the membrane box 1 on the demoulding device 8, improve the matching accuracy between the mold and the device during the demoulding process, thereby improving the demoulding efficiency and the integrity of the test block.

[0031] The implementation principle of a concrete test block mold in the embodiment of the present application is: When demoulding is required, external air enters the positioning groove 3 through the air inlet 4, and then is evenly injected into the gap between the concrete test block and the inner wall of the membrane box 1 along the air path 6 formed by the one-to-one correspondence between the air inlet 4 and the air outlet 5 on the inner wall of the membrane box 1. This process realizes the soft ejection of the concrete test block. Through the effect of gas pressure, the friction between the test block and the side wall of the membrane box 1 is significantly reduced, thereby effectively reducing the demoulding resistance. This soft demoulding method not only protects the integrity of the test block, but also greatly improves the demoulding speed.

[0032] In addition, the positioning edge 7 provided at the bottom of the film box 1 can ensure the precise positioning of the mold on the demoulding device 8, making the cooperation between the mold and the device more compact and accurate. This high-precision cooperation further improves the demoulding efficiency, ensures the stability of the test block during the demoulding process, and avoids the damage of the test block caused by the shaking or misalignment of the mold.

[0033] Example 2 The embodiment of the present application further discloses a demoulding device 8. The demoulding device 8 disclosed in the embodiment of the present application is adapted to the concrete test block mold as described in Example 1.

[0034] like Figure 4 As shown, the demoulding device 8 includes a base 801, and a positioning block 802 and a positioning seam 803 are provided on the top of the base 801. The positioning block 802 cooperates with the positioning groove 3, and the positioning seam 803 cooperates with the positioning edge 7. An ejector pin 804 is provided at the center of the top of the positioning block 802, and a plurality of vents 805 are provided around the ejector pin 804 on the top of the positioning block 802. The vents 805 are evenly distributed around the ejector pin 804, and the vents 805 correspond to the air inlet 4 on the positioning block 802 one by one, which can ensure that the gas is evenly distributed. The number of vents 805 only affects the flow rate of air injected into the positioning groove 3. The user can choose to set the number of vents 805 according to actual conditions, and this application does not make any restrictions here. An air compressor (not shown in the figure) is provided in the base 801, and the air compressor is connected to the vents 805 to provide air flow to the vents 805.

[0035] Specifically, the base 801 can be made of cast iron or stainless steel, which has high strength. The ejector pin 804 is cylindrical, and the ejector pin 804 is made of stainless steel or high-strength steel, and can be fixed on the positioning block 802 by threading or welding. The air compressor installed in the base 801 can be connected to the vent hole 805 through a pipeline to provide air flow for the vent hole 805.

[0036] The demoulding device 8 can be adapted to the concrete test block mold with a pinhole 2, a positioning groove 3, an air inlet 4, an air outlet 5 and a positioning edge 7, so as to achieve precise positioning and efficient demoulding. The positioning block 802 cooperates with the positioning groove 3, and the positioning seam 803 cooperates with the positioning edge 7 to ensure the accurate positioning of the mold; the ejector pin 804 passes through the pinhole 2 to reduce the air flowing from the pinhole 2 between the membrane box 1 and the concrete test block, and the vent hole 805 is connected to the air compressor, thereby forming a complete passage from the air compressor through the vent hole 805, the positioning groove 3, the air inlet 4, and the air passage 6 to the inside of the membrane box 1, thereby realizing the effective separation of the test block from the inner wall of the membrane box 1 by using gas pressure, avoiding damage or sticking of the test block during demoulding by using the ejector pin 804, and improving the demoulding efficiency and quality.

[0037] The implementation principle of a demoulding device 8 in the embodiment of the present application is: After the concrete test block is prepared, when the demoulding device 8 is used for demoulding, the concrete test block mold is first moved to the top of the base 801 to ensure that the positioning block 802 is accurately embedded in the positioning groove 3 of the concrete test block mold, and the ejector pin 804 is inserted into the pinhole 2 but temporarily does not contact the concrete test block, and at the same time, the positioning seam 803 is tightly fitted with the positioning edge 7 of the concrete test block mold to achieve accurate alignment of the mold. At this time, the air compressor is started, and the high-pressure gas quickly enters the mold through the vent hole 805, passes through the air inlet 4 and the air path 6 in turn, and finally reaches the inside of the membrane box 1.

[0038] As the air pressure inside the membrane box 1 gradually increases, the air between the membrane box 1 and the concrete test block is quickly compressed and discharged, and released to the outside through the air outlet 5. In this process, the gas pressure produces a uniform, outward thrust on the test block, which significantly reduces the adhesion between the test block and the inner wall of the membrane box 1.

[0039] Then, the concrete test block mold is slowly moved toward the base 801 until the concrete test block mold contacts the base 801. Since the test block is already in a relatively loose state at this time, the ejector pin 804 can easily pass through the pinhole 2, further facilitating the separation of the test block from the membrane box 1. During the entire demoulding process, due to the effect of gas pressure, the test block is less impacted, effectively avoiding damage to the test block or surface defects caused by direct mechanical force.

[0040] Example 3 The embodiment of the present application also discloses a demoulding production line, including a control center, a transfer robot 9, a demoulding device 8, a static rack 10, a mold conveyor belt and a coding workstation.

[0041] like Figure 4As shown, specifically, the control center connects various devices through a computer network to achieve coordinated control of the entire production line. The control center can adjust the working speed of each device according to demand to ensure efficient operation. The transfer robot 9 includes a transfer conveyor belt 901, a multi-axis robotic arm 902 and a claw 903. The multi-axis robotic arm 902 is arranged on the transfer conveyor belt 901, and the claw 903 is installed at the execution end of the multi-axis robotic arm 902. The demoulding device 8 is arranged on one side of the transfer conveyor belt 901, and is used to eject the test block from the mold. The static rack 10 is arranged on the side of the transfer conveyor belt 901 away from the demoulding device 8, and is used to temporarily store the concrete test block mold. The feed end of the mold conveyor belt is arranged at one end of the transfer conveyor belt 901, and is used to transport empty concrete test block molds. The coding workstation is used to spray the process code on the surface of the concrete test block after demoulding, and send the process code information to the control center. The transfer conveyor belt 901 is used to transport the multi-axis robot arm 902. The multi-axis robot arm 902 and the claw 903 are used to grab the concrete test block mold from the static rack 10 and send it to the demoulding device 8. The concrete test block that has completed the demoulding operation is sent to the coding workstation, and the empty concrete test block mold that has completed the demoulding operation is sent to the mold conveyor belt. The transfer robot 9 is connected to the control center signal to realize automatic operation.

[0042] like Figure 4 As shown, specifically, the static rack 10 includes a rack body 1001, a tray 1002, a pressure sensor and a first control device. The rack body 1001 is a multi-layer structure, the tray 1002 is arranged on the rack body 1001, and the pressure sensor is arranged between the tray 1002 and the rack body 1001. The pressure sensor is connected to the first control device by signal, and is used to detect whether there is a concrete test block mold on the tray 1002, and send a signal to the control center. The first control device is connected to the pressure sensor signal to ensure the information recording of the static rack 10.

[0043] In actual use, when the concrete test block mold containing the concrete test block is placed on the tray 1002, the pressure sensor detects the pressure change on the tray 1002, thereby determining whether there is a concrete test block mold on the tray 1002. The first control device is connected to the pressure sensor signal, and can record the time that the membrane box 1 is stationary on the tray 1002 through its built-in timer. When the concrete test block mold is placed on the tray 1002, the pressure sensor activates the first control device to start timing, and determines whether the concrete test block mold has stayed on the tray 1002 for a sufficient time. If the residence time of the concrete test block mold reaches or exceeds the preset time, the first control device will send a signal to the control center, and the transfer robot 9 will complete the transfer of the stationary concrete test block mold to the demolding device 8 for demolding operation. After the demolding operation is completed, the concrete test block is transported to the coding workstation by the transfer robot 9, and the empty concrete test block mold is transported to the mold conveyor belt by the transfer robot 9 for recycling.

[0044] like Figure 4 As shown, the coding workstation includes a feeding conveyor belt 12, an inkjet printer 11 and a cargo box 13. The inkjet printer 11, the feeding conveyor belt 12 and the cargo box 13 are sequentially arranged on one side of the transfer conveyor belt 901 along the first direction. The feeding conveyor belt 12 is arranged along the first direction, and the end of the feeding conveyor belt 12 close to the inkjet printer 11 is the feeding end. The feeding conveyor belt 12 is used to transport concrete test blocks after demoulding and inkjet operation. The inkjet printer 11 includes a base frame 1101, a support platform 1102, a pusher 1103, an inkjet assembly 1104 and a second control device. The support platform 1102 is arranged on the base frame 1101, and the pusher 1103 is arranged on the base frame 1101 and is located on the side of the support platform 1102 away from the feeding conveyor belt 12. The ink nozzle of the inkjet assembly 1104 is arranged above the support platform 1102 and the inkjet angle is directed to the support platform 1102. The second control device is connected with the inkjet assembly 1104, the pusher 1103 and the control center signal.

[0045] The base frame 1101 of the inkjet printer 11 supports the entire device, the support platform 1102 is used to place the concrete specimen to be coded, and the inkjet assembly 1104 sprays ink vertically to ensure the clarity and accuracy of the coding. The pusher 1103 can push the concrete specimen that has been coded on the support platform 1102 to move it to the unloading conveyor belt 12. The second control device realizes the linkage control of the inkjet assembly 1104 and the pusher 1103, and is connected to the control center, thereby improving the automation degree and coding efficiency of the coding process.

[0046] like Figure 4 As shown, the inkjet printer 11 also includes a camera 1105 and a rotating assembly. The camera 1105 is arranged above the support platform 1102, and the support platform 1102 is connected to the base frame 1101 through the rotating assembly. The top of the support platform 1102 is coated with pure white paint, and the camera 1105 is pointed at the support platform 1102. The second control device is connected to the camera 1105 and the rotating assembly signal.

[0047] The camera 1105 is arranged above the base 1102, and the shooting angle is vertically downward, which is conducive to accurately capturing the position information of the concrete specimen. The top of the base 1102 is coated with pure white paint, which can improve the contrast between the concrete specimen and the background, making it easier for the camera 1105 to identify the outline of the concrete specimen. When the concrete specimen is placed on the base 1102, the camera 1105 can capture the image of the concrete specimen and obtain the position information of the concrete specimen through the control chip integrated with image processing technology in the second control device. After detecting the position information of the concrete specimen, the second control device can compare the real-time position with the preset position, and transmit signals to the rotating component and the pushing member 1103. The rotating component drives the support platform 1102 to rotate so that the concrete specimen on the support platform 1102 rotates to a suitable orientation, and the pushing member 1103 can push the concrete specimen on the support platform 1102 to move it to a suitable position. The rotating component drives the support platform 1102 to rotate so that the pushing member 1103 can push the concrete specimen on the support platform 1102 from different angles to a suitable position, thereby ensuring that the inkjet component 1104 can accurately align the concrete specimen for coding, thereby improving the accuracy and efficiency of coding.

[0048] The implementation principle of a demoulding production line in an embodiment of the present application is that the operation of the entire demoulding production line is uniformly scheduled by the control center. Through the computer network, the control center maintains real-time communication with each device, and flexibly adjusts the working speed and state of each device according to production needs to ensure the efficient operation of the entire production line. The transfer robot 9 realizes the precise grasping, handling and release of the concrete test block mold through the coordinated work of the transfer conveyor belt 901, the multi-axis robot arm 902 and the clamping claw 903. Under the command of the control center, the transfer robot 9 can grab the test block mold that has been stationed from the static rack 10 and send it to the demoulding device 8 for demoulding operation; then, the demoulded test block is sent to the coding workstation, and the empty mold is sent back to the mold conveyor belt for recycling. The static rack 10 realizes intelligent monitoring of the mold static time through the cooperation of the pressure sensor and the first control device. When the mold with the concrete test block is placed on the tray 1002, the pressure sensor detects the pressure change and activates the first control device to start timing. When the standing time reaches the preset value, the first control device sends a signal to the control center to trigger the next operation of the transfer robot 9. The demoulding device 8 is located on one side of the transfer conveyor belt 901, and is specifically used to eject the test block from the mold. After receiving the mold sent by the transfer robot 9, the demoulding device 8 quickly and stably completes the demoulding operation to ensure that the test block is intact. The coding workstation is the last process of the production line, which is responsible for spraying the process code on the surface of the test block after demoulding. The inkjet printer 11 captures the test piece position information through the camera 1105, and drives the rotating assembly to adjust the direction and position of the test block to ensure that the inkjet assembly 1104 can accurately align the test block for coding. At the same time, the pusher 1103 pushes the coded test block to the unloading conveyor belt 12 for subsequent processing.

[0049] The mold conveyor transports the empty concrete test block molds back to the starting point, forming a closed loop to prepare for the next production. This design not only improves production efficiency, but also realizes the efficient recycling and reuse of molds.

[0050] To sum up, the demoulding production line disclosed in the embodiment of the present application realizes the full process automated production of concrete test blocks from static, demoulding to coding through highly automated equipment and precise control systems, which greatly improves production efficiency and product quality and reduces labor costs and error rates.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
