If the specific posture changes, the directional indication will also change accordingly.

[0021] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0022] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0023] like Figure 1-5 As shown, an aerated concrete bidirectional cutting and automatic punching and blanking device 100 is used to cut aerated concrete panels. It includes a frame 110, a first cutting component 120, a second cutting component 130, a punching component 140, and a transfer component 150. The frame 110 includes a first cutting position 111, a second cutting position 112, and a punching position 113 arranged sequentially. The first cutting component 120 is located at the first cutting position 111 and is used to cut along a first direction of the aerated concrete panel. The second cutting component 130 is located at the second cutting position 112 and is used to cut along a second direction of the aerated concrete panel to form an aerated concrete blank. The punching component 140 is located at the punching position 113 and is used to punch the aerated concrete blank to form an aerated concrete block. The transfer component 150 is used to sequentially move the aerated concrete to the first cutting position 111, the second cutting position 112, and the punching position 113. For example, in this embodiment, the aerated concrete panel is a cuboid, the aerated concrete preform is a cuboid, and the aerated concrete block is also a cuboid. That is, the first cutting component 120 cuts the aerated concrete panel into strips, and then the second cutting component 130 cuts the strips into cuboid blocks. It should be noted that the volume of the aerated concrete preform is larger than that of the aerated concrete block. Figure 7As shown, in this embodiment, after passing through the first cutting component 120 and the second cutting component 130, the aerated concrete blank is not completely cut off. A 20mm allowance D1 remains in the middle of the aerated concrete blank, and the gap D2 cut by the first cutting component 120 and the second cutting component 130 is 4mm of aerated concrete. After the punching component 140 punches off the allowance, an aerated concrete block is obtained. It can be understood that since a 20mm allowance D1 needs to be left in the middle of the aerated concrete blank, two sets of the first cutting component 120 and the second cutting component 130 are provided. The two sets of the first cutting component 120 are respectively set on the upper and lower sides of the aerated concrete blank, and the two sets of the second cutting component 130 are respectively set on the upper and lower sides of the aerated concrete blank, so that the first cutting component 120 and the second cutting component 130 can cut the upper and lower sides of the aerated concrete blank at the same time, improving processing efficiency. At the same time, maintaining the integrity of the aerated concrete blank is beneficial for the transfer component 150 to handle.

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the blanking assembly 140 includes a first driving member 141, a blanking cutter 142, and a support platform 143. The first driving member 141 is mounted on the frame 110 and connected to the blanking cutter 142. The first driving member 141 drives the blanking cutter 142 to reciprocate along the Z-axis. The support platform 143 is located at the blanking position 113, and a gap 1432 for collecting waste material is formed on the support platform 143. Exemplarily, the first driving member 141 is a retractable component such as a cylinder, hydraulic rod, or electric push rod. The blanking cutter 142 corresponds to the upper die in the mold, and the support platform 143 corresponds to the lower die in the mold. The support platform 143 includes multiple columns spaced in multiple rows and columns. The cross-sectional area of ​​the columns should be equal to or slightly smaller than the cross-sectional area of ​​the aerated concrete block. The gaps between adjacent columns are used to collect the blanked waste material.

[0025] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the support platform 143 has a support surface 1431. The punching assembly 140 also includes a collecting plate 144 and a telescopic member 145. The collecting plate 144 is disposed in the gap 1432, and the position of the collecting plate 144 is lower than the support surface 1431. The telescopic member 145 connects the frame 110 and the collecting plate 144. Exemplarily, the collecting plate 144 is slidably mounted on the support platform 143. When the waste material in the gap 1432 is almost full, the telescopic member 145 pushes the collecting plate 144 up to a position flush with the support surface 1431, which facilitates the removal of waste material. The telescopic member 145 is a telescopic component such as a cylinder, a hydraulic rod, or an electric push rod.

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, in one embodiment, the punching assembly 140 further includes a first slide rail 146, a mounting bracket 147, and a push plate 148. The first slide rail 146 is arranged along the Y-axis direction of the frame 110. The mounting bracket 147 is slidably mounted on the first slide rail 146. The push plate 148 is connected to the mounting bracket 147, and the position of the push plate 148 is not lower than the bearing surface 1431. For example, the position of the push plate 148 can be flush with the bearing surface 1431 or slightly higher than the bearing surface 1431. The push plate 148 has two functions. The first function of the push plate 148 is to push the cut aerated concrete blocks to one side of the aerated concrete bidirectional cutting and automatic punching and blanking device 100 for easy collection. The second function of the push plate 148 is to push the punched residue to the other side of the aerated concrete bidirectional cutting and automatic punching and blanking device 100 for easy cleaning. It should be noted that after the aerated concrete blank is punched into aerated concrete blocks by the punching component 140, the pusher plate 148 first pushes the aerated concrete blocks to one side. Then, the telescopic component 145 drives the collecting plate 144 to rise to a position flush with the bearing surface 1431, and then pushes the remaining material to the other side for cleaning.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the first cutting assembly 120 includes a second driving member 121, a first protective cover 122, and a first cutting blade 123. Both the second driving member 121 and the first protective cover 122 are mounted on the frame 110. The second driving member 121 is connected to the first cutting blade 123, and the first cutting blade 123 is disposed within the first protective cover 122. The first protective cover 122 is provided with multiple first nozzles. For example, the first cutting blade 123 is disposed within the first protective cover 122 to prevent injury to personnel during operation. The nozzles are used to spray water mist, aiming to reduce dust falling from the first cutting blade 123 when cutting the aerated concrete panel, thus avoiding dust pollution. The second driving member 121 is a motor, and the first cutting blade 123 includes multiple spaced-apart first blades, enabling the aerated concrete panel to be cut completely in one pass by the first cutting blade 123, which is beneficial for improving the processing efficiency of the aerated concrete bidirectional cutting and automatic punching and blanking device 100. It should also be noted that the spacing between the multiple first blades is adjustable. The spacing between the first blades can be adjusted according to the actual needs and the size of the aerated concrete block.

[0028] like Figure 1 , Figure 2 , Figure 4As shown, in one embodiment, the second cutting assembly 130 includes a third driving member 131, a second protective cover 132, and a second cutting blade 133. Both the third driving member 131 and the second protective cover 132 are mounted on the frame 110. The third driving member 131 is connected to the second cutting blade 133, which is disposed within the second protective cover 132. The second protective cover 132 is provided with multiple second nozzles. For example, the second cutting blade 133 is disposed within the second protective cover 132 to prevent injury during operation. The nozzles spray water mist to reduce dust falling from the aerated concrete slab during cutting, thus preventing dust pollution. The third driving member 131 is a motor. The second cutting blade 133 includes multiple spaced second blades, allowing the aerated concrete slab to be cut in two passes, which improves the processing efficiency of the aerated concrete bidirectional cutting and automatic punching and blanking device 100. It should also be noted that the spacing between the multiple second blades is adjustable. The spacing between the second blades can be adjusted according to the actual needs and the size of the aerated concrete block.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the frame 110 includes a first frame 114, a second frame 115, a third frame 116 and a fourth frame 117 connected in sequence. A first cutting assembly 120 is mounted on the first frame 114, a second cutting assembly 130 is mounted on the third frame 116, and a punching assembly 140 is mounted on the fourth frame 117.

[0030] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the transfer assembly 150 includes a first conveyor belt 151, a first robotic arm 152, a second conveyor belt 153, and a second robotic arm 154. The first conveyor belt 151 is mounted on a first frame 114, the first robotic arm 152 is mounted on a second frame 115, and the second conveyor belt 153 and the second robotic arm 154 are mounted on a third frame 116. Exemplarily, the first conveyor belt 151 and the second conveyor belt 153 are independently configured. This design allows the first conveyor belt 151 and the second conveyor belt 153 to cooperate with the first cutting assembly 120 and the second cutting assembly 130, respectively. That is, when the first cutting assembly 120 is working, the second cutting assembly 130 can also work simultaneously, which helps to improve work efficiency.

[0031] like Figure 1 , Figure 2 , Figure 4As shown, in one embodiment, the first manipulator 152 includes a fourth drive member 1521, a rotating member 1522, and a gripper 1523. The fourth drive member 1521 is mounted on the second frame 115, and the rotating member 1522 is connected between the fourth drive member 1521 and the gripper 1523. The fourth drive member 1521 is used to drive the gripper 1523 to reciprocate along the X-axis and Z-axis directions.

[0032] like Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment, the second robot 154 includes a second slide rail 1541, a lifting member 1542, and a clamping plate 1543. The second slide rail 1541 is arranged on opposite sides of the second conveyor belt 153 along the X-axis direction. The lifting member 1542 is connected between the second slide rail 1541 and the clamping plate 1543. The clamping plate 1543 can reciprocate along the X-axis and Z-axis directions.

[0033] The working process of the aerated concrete bidirectional cutting and automatic punching and blanking device 100 is as follows: A whole aerated concrete slab is placed at the first cutting position 111. The first cutting component 120 is started to perform the first cut on the aerated concrete slab. Simultaneously, water mist is sprayed from the nozzle. The first conveyor belt 151 starts to transport the aerated concrete slab after the first cut. The first robotic arm 152 then grabs the aerated concrete slab after the first cut, rotates it 90° to change its orientation, and then places it on the second conveyor belt 153 and transports it to the second cutting position 112. At this point, the second conveyor belt 153 stops, and the second cutting component 130 is started to cut the aerated concrete slab. The second cutting is performed, during which the nozzle sprays water mist. Then the second conveyor belt 153 is started again to transport the aerated concrete blank to the position of the second robot arm 154. The second robot arm 154 is then started to transport the aerated concrete blank to the punching position 113. The punching component 140 is started to punch the aerated concrete block. The push plate 148 pushes the aerated concrete block to one side of the aerated concrete bidirectional cutting and automatic punching and blanking device 100. Then the telescopic component 145 drives the collecting plate 144 to rise to a position flush with the bearing surface 1431. Then the push plate 148 is used to push the punched residue to the other side of the aerated concrete bidirectional cutting and automatic punching and blanking device 100.
