The multiple first support columns 0162 are used to support a plurality of stiffening trusses 003 and / or square tube columns 002. The plurality of stiffening trusses 003 are arranged at intervals in sequence along the second direction 009.

[0107] It should be noted that when the precast wall panel 001 is a whole wall, the precast wall panel 001 includes two square tube columns 002 on the outermost sides and a plurality of stiffening trusses 003 located at the middle positions. In this case, the second support columns 0165 support the two outermost square tube columns 002, and the first support columns 0162 support the plurality of stiffening trusses 003.

[0108] When the precast wall panel 001 is a wall panel including a door opening and / or a window opening, as Figure 3 shown in the figure, the precast wall panel 001 includes two square tube columns 002 on the outermost sides, square tube columns 002 located on the sides of the door opening and / or the window opening, and stiffening trusses 003 located between the square tube columns 002. In this case, the second support columns 0165 support the two outermost square tube columns 002, and the first support columns 0162 support a plurality of stiffening trusses 003 and / or square tube columns 002, which is specifically determined according to the actual wall panel design. That is, the first support column 0162 is used to support the precast components between the two outermost square tube columns 002, and the second support column 0165 is used to support the two outermost square tube columns 002.

[0109] The number of the clamping mechanisms 019 is multiple. The clamping mechanisms 019 are arranged on both sides of each first support column 0162.

[0110] The clamping mechanisms 019 on each side of the first support column 0162 are linkage structures, and can clamp or release multiple stiffening trusses 003 simultaneously. When the stiffening trusses 003 and the square pipe columns 002 are placed on the support table 016 and the positioning is completed, they can be clamped simultaneously through the clamping mechanisms 019, which not only makes the positioning accurate but also improves the assembly efficiency.

[0111] Please refer to Figure 4 and Figure 5 , Figure 4 which shows a schematic structural view of the clamping mechanisms arranged on both sides of the first support column, Figure 5 and which shows a partial schematic view of the clamping mechanism.

[0112] Specifically, the clamping mechanism 019 may include a quick-release plate 0191, a plurality of fixing members 0192, and a linkage assembly. The quick-release plate 0191 is fixedly installed on the side wall of the first support column 0162 of the support table 016. The plurality of fixing members 0192 are fixedly arranged on the quick-release plate 0191 at intervals in the second direction 009, and the plurality of fixing members 0192 are located on the same straight line. The linkage assembly is slidably arranged on the plurality of fixing members 0192 in the second direction 009. The linkage assembly includes a plurality of movable members 0197, and the plurality of movable members 0197 are arranged in one-to-one correspondence with the plurality of fixing members 0192. When the linkage assembly moves relative to the plurality of fixing members 0192 in the second direction 009, the plurality of movable members 0197 move synchronously. The corresponding fixing member 0192 and movable member 0197 form a clamping space for clamping the stiffening truss 003. The plurality of movable members 0197 are linked so that the plurality of movable members 0197 approach or move away from their corresponding fixing members 0192 simultaneously.

[0113] The fixing members 0192 and the linkage assembly are detachably installed on the side wall of the first support column 0162 through the quick-release plate 0191, so that the clamping mechanism 019 can be conveniently installed or removed from the first support column 0162 as a whole.

[0114] Since the stiffening truss 003 is disposed on the first support column 0162, the clamping mechanism 019 is mounted on the side wall of the first support column 0162. In order to better clamp a plurality of stiffening trusses 003 without interfering with the arrangement of the stiffening trusses 003. Optionally, the quick-release plate 0191 is fixed to the side wall of the first support column 0162 and does not protrude above the upper surface of the first support column 0162, and a plurality of fixing members 0192 are fixed to the quick-release plate 0191 and at least partially protrude above the upper surface of the first support column 0162. A plurality of movable members 0197 in the linkage assembly are alternately arranged with the plurality of fixing members 0192 in sequence, so that one movable member 0197 and one fixing member 0192 form a group, and the plurality of movable members 0197 at least partially protrude above the upper surface of the first support column 0162.

[0115] The movable member 0197 and the fixing member 0192 in the same group are oppositely arranged to form a clamping space. That is to say, by fixing the fixing member 0192 and moving the movable member 0197 closer to or away from the fixing member 0192, the stiffening truss 003 can be clamped or loosened.

[0116] In order to enable the plurality of movable members 0197 to move synchronously, optionally, the linkage assembly may further include a linkage rod 0198. The linkage rod 0198 is slidably disposed through the plurality of fixing members 0192 along the second direction 009, and the plurality of movable members 0197 are sequentially and spacedly fixed to the linkage rod 0198 along the second direction 009. The linkage rod 0198 drives the plurality of movable members 0197 to move synchronously to approach or move away from the corresponding fixing member 0192.

[0117] As Figure 5 shown, the linkage rod 0198 is disposed through all the fixing members 0192. After the threading is completed, the movable members 0197 and the fixing members 0192 are alternately arranged at intervals in sequence, and all the movable members 0197 can move synchronously with the linkage rod 0198. In other words, by controlling the sliding of the linkage rod 0198, a plurality of stiffening trusses 003 can be simultaneously clamped and fixed or synchronously loosened.

[0118] Please continue to refer to Figure 5 shown, the number of the linkage rods 0198 is at least two. The fixing member 0192 can be designed as an L-shaped structure. One ear of the L-shaped fixing member 0192 is fixed on the quick-release plate 0191, and the other ear corresponds to the movable member 0197 for clamping the stiffening truss 003. A through hole can be formed on the other ear. The number of the through holes is the same as the number of the linkage rods 0198, and the positions correspond one by one. The linkage rod 0198 is slidably passed through the through holes, and at least two linkage rods 0198 are fixedly connected at the ends to form an integral body.

[0119] By providing at least two linkage rods 0198 fixedly connected, and the at least two linkage rods 0198 are respectively passed through the through holes, it is possible to prevent the linkage assembly from rotating relative to the fixed member 0192. That is to say, the linkage assembly has only the degree of freedom to slide along the second direction 009 relative to the fixed member 0192. During the sliding process, the moving member 0197 of the linkage assembly approaches or moves away from the cooperating fixed member 0192.

[0120] In the above structure, through holes are also provided on the moving member 0197. The number of through holes provided on the moving member 0197 is the same as the number of linkage rods 0198, and the positions correspond one by one. The moving member 0197 and the linkage rods 0198 are fixedly connected relatively.

[0121] In other alternative embodiments, a fastener may also be included. During installation, the linkage rod 0198 sequentially passes through the fixed member 0192, the fastener, and the moving member 0197. After all the fixed members 0192 and the moving members 0197 are passed through and the position of the moving member 0197 is determined, the moving member 0197 and the linkage rod 0198 are fixed by the fastener, which is convenient for installation and has convenient operation.

[0122] Further, in order to enhance the clamping effect of the moving member 0197 and the fixed member 0192 on the stiffening truss 003, a contact plate 0196 may be elastically provided on the opposite side of the moving member 0197 and / or the fixed member 0192. For example, please refer to Figure 5 , a contact plate 0196 is elastically provided on the side of the moving member 0197 close to the fixed member 0192 in the same group. The contact plate 0196 is connected to the moving member 0197 by a spring. The contact plate 0196 and the fixed member 0192 are used to abut against both sides of the stiffening truss 003.

[0123] Further, the clamping mechanism 019 may further include a driving member. The driving member is fixed to the first support column 0162 of the support platform 016. The driving member is in transmission connection with the linkage assembly and is used to drive the linkage assembly to slide along the second direction 009. In other words, the driving member may adopt a driving cylinder. The power output end of the driving cylinder is fixedly connected to the linkage rod 0198 and is used to drive the linkage rod 0198 to slide along the second direction 009.

[0124] For the convenience of disassembling, assembling, and maintaining the clamping mechanism 019, optionally, the driving member can be used to separately control the linkage assemblies in each clamping mechanism 019. During the disassembly, assembly, and maintenance process, it can be quickly disassembled through the quick-release plate 0191, which is convenient for maintenance. Of course, in other alternative embodiments, all the clamping mechanisms 019 may adopt a set of driving members, and a set of driving members is used to simultaneously control the movement of all the linkage assemblies. The present application does not limit the specific implementation manner and is determined according to actual requirements.

[0125] Optionally, in order to facilitate the positioning of the square tube column 002 during assembly, positioning protrusions are provided on the top surfaces of the first support column 0162 and / or the second support column 0165.

[0126] Corresponding to the positioning protrusions, process holes are provided at corresponding positions on the square tube column 002. The positioning protrusions are used to cooperate with the process holes to position the square tube column 002. During operation, the square tube column 002 is lifted by a crane, and the process holes of the square tube column 002 are matched with the positioning protrusions on the support column, and the square tube column 002 is gradually lowered. With the self-weight of the square tube column 002, the cooperation of the positioning convex column and the process hole, the positioning of the square tube column 002 can be achieved.

[0127] In the embodiment of the present application, the support platform 016 is slidably installed on the bracket 014. By adjusting the distances and positions of the first support column 0162 and the second support column 0165, it is possible to match the prefabricated wall panel 001 to be assembled. The second support column 0165 receives the square tube column 002, and the first support column 0162 receives the stiffening truss 003 and the square tube column 002. While supporting the components of the prefabricated wall panel 001 to be assembled, it can also perform positioning. The stiffening truss 003 after positioning is fixed by the clamping mechanism 019, so that the square tube column 002 and all the stiffening trusses 003 are relatively fixed, facilitating subsequent welding operations. In a clamping mechanism 019, by installing a plurality of fixing members 0192 and a linkage assembly on the quick-release plate 0191, and the quick-release plate 0191 is installed on the first support column 0162, the quick disassembly and quick installation of the clamping mechanism 019 can be realized. By providing a plurality of fixing members 0192 and a plurality of movable members 0197, the fixing members 0192 and the movable members 0197 are arranged alternately in sequence and form a group in pairs. The same group of fixing members 0192 and movable members 0197 corresponds to a stiffening truss 003. By driving the plurality of movable members 0197 to move synchronously relative to the plurality of fixing members 0192 through the linkage rod 0198, the stiffening truss 003 can be clamped or released simultaneously. The fixing is convenient, and the fixing efficiency is greatly improved. It also improves the assembly efficiency during the assembly process, is easy to operate, has high assembly accuracy, and has a wide application range. It can be applied to the assembly process of prefabricated wall panels 001 of different specifications and sizes, and has strong practicability and operability.

[0128] Specifically, the steel bar passing station 020 may include an alignment mechanism 022 and a third welding part. The alignment mechanism 022 is used to cooperate with the first wall panel to assist the steel bar 004 to pass smoothly through the steel bar passing hole, and the third welding part is used to weld and fix the connection between the steel bar 004 after passing through and the stiffening truss 003 in the first wall panel.

[0129] Please refer to FIG. 6, which shows a schematic structural diagram of the prefabricated wall panel 001.

[0130] Since through holes are reserved when the stiffening trusses 003 are formed, the through holes on multiple stiffening trusses 003 in the assembled first wall panel will correspond to each other, forming multiple steel bar passing holes located on the same straight line. The steel bar passing station 020 is to pass multiple steel bars 004 through the multiple steel bar passing holes one by one, and after passing, the steel bars 004 and the first wall panel are welded and fixed.

[0131] When passing the steel bars 004, the steel bars 004 are prone to downward deflection due to gravity. Also, since the reserved through holes on the stiffening trusses 003 are small, it is difficult for the steel bars 004 to align with the reserved through holes on each stiffening truss 003. It is necessary to manually assist the ends of the steel bars 004 to align with the reserved through holes on each stiffening truss 003 in turn, which results in a low penetration efficiency of the steel bars 004 and affects the production efficiency of the precast wall.

[0132] To improve the penetration efficiency of the steel bars 004, an alignment mechanism 022 is provided at the steel bar passing station 020 in the precast wall panel production line 100 provided in the embodiments of the present application. Please refer to Figure 6 and Figure 7 , Figure 7 shown in the structural schematic diagram of the alignment mechanism 022.

[0133] The alignment mechanism 022 may include a base 0221 and a plurality of alignment components 0223. The base 0221 extends along the second direction 009, and the plurality of alignment components 0223 are sequentially arranged at intervals along the second direction 009 on the base 0221. Each alignment component 0223 is used to assist the steel bar 004 to align with the steel bar passing hole.

[0134] Among them, the base 0221 is mainly used to carry the plurality of alignment components 0223. In other words, the plurality of alignment components 0223 need to be installed on the base 0221, so that the plurality of alignment components 0223 can be moved at one time through the base 0221, so that the plurality of alignment components 0223 can be simultaneously moved to the target position. Here, the target position refers to the position where the steel bar 004 can be assisted to align with the steel bar passing hole.

[0135] In the present application, there are a plurality of alignment components 0223, and the plurality of alignment components 0223 are all used to assist the steel bar 004 to align with one of the steel bar passing holes. In some embodiments, the alignment component 0223 may include, for example, Figure 8The shown funnel-shaped structure may include a first clamping body 0224 and a second clamping body 0226 that cooperate with each other. When it is necessary to assist the steel bar 004 to align with the steel bar passing hole, the first clamping body 0224 and the second clamping body 0226 are closed to form a funnel-shaped through hole. The funnel-shaped through hole includes a first opening with a larger opening and a second opening with a smaller opening. The second opening is aligned with the steel bar passing hole behind it. The steel bar 004 first penetrates into the funnel-shaped through hole from the first opening at the front end, then penetrates out from the second opening, and then smoothly passes through the steel bar passing hole behind the second opening. When the steel bar 004 sequentially penetrates through each through hole, the two parts of each funnel-shaped through hole are separated from each other, and a gap is formed between the first clamping body 0224 and the second clamping body 0226, so that the first clamping body 0224 and the second clamping body 0226 can be removed from both sides of the steel bar 004 along this gap.

[0136] In this application, a plurality of alignment assemblies 0223 are arranged on the base 0221 along the second direction 009. Each alignment assembly 0223 is used to assist the steel bar 004 to align with the steel bar passing hole, so that when the steel bar 004 penetrates forward along the second direction 009, it can sequentially align with the corresponding through holes by means of each alignment assembly 0223, thereby realizing the rapid penetration of the steel bar 004 and improving the processing or construction efficiency.

[0137] In some specific embodiments, the alignment mechanism 022 may further include a driving member. The driving member is installed on the base 0221. The driving member includes a plurality of moving units 030 arranged at intervals along the second direction 009. Each moving unit 030 includes a first mounting portion 0301 and a second mounting portion 0303 arranged oppositely. A plurality of alignment assemblies 0223 are installed on a plurality of moving units 030 in a one-to-one correspondence. The driving member controls each alignment assembly 0223 to move to the front of the corresponding steel bar passing hole and / or move away from the front of the corresponding steel bar passing hole through the moving unit 030.

[0138] Optionally, a plurality of alignment assemblies 0223 are installed on a plurality of moving units 030 in a one-to-one correspondence along the second direction 009. The driving member can control the movement of the moving unit 030. Optionally, the driving member may include a track module, and at least one end of the moving unit 030 is connected to the track module, so that the movement of the moving unit 030 can be controlled through the track module. Alternatively, the driving member may be a cylinder module, and at least one end of the moving unit 030 is connected to the cylinder module, so that the movement of the moving unit 030 can be controlled through the cylinder module.

[0139] In this application, each mobile unit 030 may include a first mounting portion 0301 and a second mounting portion 0303 that are oppositely arranged. A plurality of alignment components 0223 are respectively mounted on the plurality of mobile units 030, and the driving member is used to control the first mounting portion 0301 and the second mounting portion 0303 of the mobile unit 030 to move towards or away from each other, so that the plurality of alignment components 0223 can be quickly and accurately moved in front of the steel bar penetration hole, and the plurality of alignment components 0223 can also be quickly removed from in front of the steel bar penetration hole.

[0140] Specifically, please refer to Figure 8 and Figure 9 As shown, each alignment component 0223 may include a first clamping body 0224 and a second clamping body 0226 that cooperate with each other. A first alignment groove 0227 is formed on one side of the first clamping body 0224 close to the second clamping body 0226, and a second alignment groove 0229 is formed on one side of the second clamping body 0226 close to the first clamping body 0224. Under the action of the driving member, the first clamping body 0224 and the second clamping body 0226 move closer to or away from each other. That is, the driving member is used to control the first clamping body 0224 and the second clamping body 0226 to close or move away from each other. When the first clamping body 0224 and the second clamping body 0226 move closer to each other until they are closed, the first alignment groove 0227 and the second alignment groove 0229 are closed to form a funnel-shaped through hole. The funnel-shaped through hole has a larger first opening and a smaller second opening in sequence along the second direction 009. When the first clamping body 0224 and the second clamping body 0226 move away from each other, the first alignment groove 0227 and the second alignment groove 0229 are opened to form a gap for the steel bar 004 to withdraw, that is, there is a gap between the first clamping body 0224 and the second clamping body 0226 after they are opened, and the width of the gap is greater than the diameter of the steel bar 004.

[0141] Specifically, before penetrating the steel bar 004, the driving member is used to control the first clamping body 0224 and the second clamping body 0226 to close each other to form a funnel-shaped through hole, so as to assist the steel bar 004 to align with the steel bar penetration hole based on the funnel-shaped through hole. When the steel bar 004 penetration operation is completed, the driving member is used to control the first clamping body 0224 and the second clamping body 0226 to open each other, so as to form a gap between the first clamping body 0224 and the second clamping body 0226, and then the alignment component 0223 can be removed from both sides of the steel bar 004 along the gap.

[0142] The first alignment groove 0227 formed on the first clamping body 0224 and the second alignment groove 0229 formed on the second clamping body 0226 both include a large-diameter end and a small-diameter end. Among the plurality of alignment components 0223, the orientations of the large-diameter ends of each alignment component 0223 relative to the small-diameter ends are the same, and the funnel-shaped through holes formed among the plurality of alignment components 0223 are located on the same straight line, which is convenient for the steel bar 004 to pass through smoothly.

[0143] Please refer toFigure 10 , which shows a schematic structural diagram of the flipping mechanism 041.

[0144] Specifically, the flipping mechanism 041 may include a frame 0411, a horizontal moving mechanism 0412, a vertical moving mechanism 0413, and a clamping assembly 043. The frame 0411 is a frame structure. The horizontal moving mechanism 0412 and the vertical moving mechanism 0413 are respectively installed on the frame 0411. The horizontal moving mechanism 0412 extends in the horizontal direction, and the vertical moving mechanism 0413 extends in the height direction, that is, extends in a third direction perpendicular to the first direction 007 and the second direction 009. The clamping assembly 043 is hinged to the horizontal moving mechanism 0412 and the vertical moving mechanism 0413. The horizontal moving mechanism 0412 and the vertical moving mechanism 0413 cooperate to move simultaneously to flip the clamping assembly 043. Among them, the clamping assembly 043 is used to install the first wall panel through which the steel bar 004 is passed. When the clamping assembly 043 flips, it will drive the first wall panel through which the steel bar 004 is passed to flip synchronously.

[0145] Optionally, please refer to Figure 11 , which shows a schematic structural diagram of the frame 0411. The frame 0411 is a rectangular frame structure, including upper and lower cross beams and longitudinal beams. The upper and lower cross beams respectively enclose an upper rectangular frame and a lower rectangular frame. The longitudinal beams connect the upper rectangular frame and the lower rectangular frame to form a hollow frame structure. In addition, a slide rail 0416 is installed between the upper and lower cross beams, and the slide rail 0416 extends vertically.

[0146] Please also refer to Figure 10 and Figure 11 , the horizontal moving mechanism 0412 is arranged on the lower rectangular frame of the frame 0411 along the second direction 009. The horizontal moving mechanism 0412 may include a first motor, a first transmission component, and a slider. The first transmission component is installed on the lower rectangular frame of the frame 0411. The first motor is connected to the first transmission component and is used to drive the first transmission component to move. The slider is slidably arranged on the first transmission component along the second direction 009. The slider is hinged to the clamping assembly 043 and is used to drive the clamping assembly 043 to move horizontally.

[0147] The vertical moving mechanism 0413 may include a second motor, a second transmission assembly, a sliding bracket 0415014 and a slide rail 0416. The slide rail 0416 is fixed between the upper and lower beams of the frame 0411 and extends in the vertical direction. The second motor is fixedly mounted on the frame 0411 and connected to the second transmission assembly. The second motor acts as a power member to drive the second transmission assembly to move. The sliding bracket 0415014 is connected to the power output end of the second transmission assembly and can move under the action of the second transmission assembly. At the same time, the sliding bracket 0415014 cooperates with the slide rail 0416 to slide up and down along the slide rail 0416 under the action of the second motor and the second transmission assembly. At the same time, the sliding bracket 0415014 is hinged with the clamping assembly 043 to drive the clamping assembly 043 to move vertically.

[0148] Please refer to Figure 10 and Figure 12 , Figure 12 The figure shows a schematic diagram of the structure of the clamping assembly 043. The clamping assembly 043 is a flat hollow frame structure, having an installation cavity for placing a first wall panel, and the first wall panel is fixed and positioned after being embedded in the installation cavity. The hollow frame of the clamping assembly 043 may include a first hinge 0434 and a second hinge 0435, the first hinge 0434 and the second hinge 0435 are located on different frames, the first hinge 0434 is transmission-connected to the horizontal moving mechanism 0412, and the second hinge 0435 is transmission-connected to the vertical moving mechanism 0413.

[0149] When the horizontal moving mechanism 0412 drives the clamping assembly 043 to move in the horizontal direction, the vertical moving mechanism 0413 drives the clamping assembly 043 to move in the vertical direction. In other words, the horizontal moving mechanism 0412 drives one end of the clamping assembly 043 to move in the horizontal direction, and the vertical moving mechanism 0413 drives the middle position of the clamping assembly 043 to rise vertically. When one end of the clamping assembly 043 moves to the middle position just past the frame 0411, the vertical moving mechanism 0413 drives the middle position of the clamping assembly 043 to drop vertically, and the horizontal moving mechanism 0412 drives one end of the clamping assembly 043 to continue to move in the horizontal direction until the middle position of the clamping assembly 043 is driven by the vertical moving mechanism 0413 to drop to a horizontal state, thereby completing a 180° flip of the clamping assembly 043 fixed with the first wall panel.

[0150] Optionally, the first wall can be transferred to the installation cavity of the clamping assembly 043 by a transfer mechanism, and the outer frame size of the clamping assembly 043 is larger than the size of the first wall to ensure that the first wall will not collide with foreign objects and be damaged during the flipping process.

[0151] For details, please refer to Figure 12, the clamping assembly 043 may include a clamping frame 0432, a clamping cylinder 0437, and a clamping plate 0438. The clamping frame 0432 has the above-mentioned installation cavity. The clamping cylinder 0437 is installed on the clamping frame 0432 and can perform telescopic movement along the third direction. The clamping plate 0438 is installed at the driving end of the clamping cylinder and is located in the installation cavity. The clamping plate 0438 can abut against the first wall panel located in the installation cavity under the telescopic action of the clamping cylinder 0437, realizing the fixation of the first wall panel and preventing the first wall panel from slipping during the flipping process.

[0152] Optionally, the first hinge portion 0434 of the clamping assembly 043 is hinged to the slider of the horizontal movement mechanism 0412, and the second hinge portion 0435 of the clamping assembly 043 is hinged to the sliding bracket 0415014 of the vertical movement mechanism 0413. Among them, the first hinge portion 0434 may be located at the middle position of the clamping frame 0432 along the third direction, and the second hinge portion 0435 is located at the middle position of the clamping frame 0432 along the fourth direction.

[0153] Please refer to Figures 13 to 17 , which respectively show the process of flipping the first wall panel by the flipping mechanism 041. In the initial state, the clamping assembly 043 is in a horizontal state. The first wall panel installed with the steel bars 004 is embedded in the installation cavity of the clamping frame 0432 under the conveyance of the conveying mechanism 077, and the clamping cylinder 0437 acts to fix the first wall panel. The slider in the horizontal movement mechanism 0412 drives one end of the clamping assembly 043 to slide along the second direction 009. At the same time, the sliding bracket 0415014 in the vertical movement mechanism 0413 drives the middle part of the clamping assembly 043 to rise along the third direction, and the clamping assembly 043 gradually tilts until it is completely erected, as shown in Figure 14 and Figure 15 shown. Then, the slider in the horizontal movement mechanism 0412 drives one end of the clamping assembly 043 to continue sliding along the second direction 009. At the same time, the sliding bracket 0415014 in the vertical movement mechanism 0413 drives the middle part of the clamping assembly 043 to descend along the third direction, and the clamping assembly 043 gradually tilts in the opposite direction until it is completely horizontal, as shown in Figure 16 and Figure 17 shown. At this time, the first wall panel installed with the steel bars 004 has been flipped by 180°. Under the conveyance of the conveying mechanism 077, the first wall panel slides out of the installation cavity of the clamping frame 0432. Finally, the horizontal movement mechanism 0412 and the vertical movement mechanism 0413 are reset to return to the initial state, facilitating the flipping of the next first wall panel.

[0154] The reverse welding station 045 is located downstream of the first flipping station 040. The reverse welding station 045 may include a second welding member for welding and fixing the joints between the square tube columns 002 and the stiffening trusses 003 on the reverse side of the first wall panel, and the joints between the steel bars 004 and the stiffening trusses 003.

[0155] Please refer to Figure 18 , which shows a schematic structure of the caulking mechanism 052.

[0156] Specifically, the caulking mechanism 052 may include an adjustment mechanism, a caulking gun, and a plurality of caulking heads. The caulking gun is mounted on the adjustment mechanism, and the plurality of caulking heads are sequentially arranged at intervals on the caulking gun. The adjustment mechanism is mounted on the workbench. The adjustment mechanism is used to adjust the position of the caulking gun horizontally and / or vertically, that is, to move the plurality of caulking heads closer to / away from the workpiece to be caulked. The horizontal position adjustment is for the plurality of caulking heads to apply snake-shaped or Z-shaped glue.

[0157] Optionally, the number of caulking heads is the same as the number of stiffening trusses 003 to be caulked and their positions correspond one by one. The caulking heads are used to apply glue to the upper surface of each stiffening truss 003. The adjustment mechanism includes a horizontal movement motor and a vertical module. The horizontal movement motor controls the caulking gun to swing horizontally, and the vertical module drives the caulking gun to move vertically.

[0158] Optionally, each caulking head can adjust the distance between the glue heads through a tightening knob to adapt to the requirements of stiffening trusses 003 with different distances.

[0159] Furthermore, the caulking station may further include an operation table, a colloid pumping station, and a secondary pumping and pressurizing device. The operation table is provided with a controller for controlling the actions of the colloid pumping station, the secondary pumping and pressurizing device, and the caulking mechanism 052. The colloid pumping station pumps the glue into the caulking gun, and then it is transported to the caulking heads through the secondary pumping and pressurizing device.

[0160] At the caulking station, the caulking mechanism 052 and the conveying mechanism 077 act simultaneously. The multiple caulking heads of the caulking mechanism 052 correspond one by one to the multiple stiffening trusses 003 of the first wall panel. The conveying mechanism 077 conveys the first wall panel to move along the conveying direction. The caulking mechanism 052 swings left and right under the action of the horizontal movement motor. When the first wall panel moves from the initial position to the panel laying station, snake-shaped or Z-shaped caulking is completed on each stiffening truss 003, which is convenient for the next laying operation.

[0161] Please refer to Figure 19 , which shows a schematic structure of the laying mechanism 065.

[0162] Specifically, the laying mechanism 065 may include a robotic arm, and a grasping tool head is provided at the power output end of the robotic arm. The grasping tool head is used to grasp the panel 005 to be laid.

[0163] Optionally, the panel 005 to be laid is arranged on one side of the conveying mechanism 077. The robotic arm is used to grab the panel 005 to be laid and then lay it on the target stiffening truss 003 of the first wall panel.

[0164] Furthermore, the panel laying station may further include a storage table 062 and a positioning table 064. Among them, the storage table 062 is used to place the panel 005 to be laid, and the positioning table 064 is used to position the panel 005 to be laid before laying, so as to improve the relative position accuracy between the gripping tool head of the robotic arm and the panel 005 to be laid. The robotic arm is used to grab the panel 005 to be laid from the storage table 062 and place it on the positioning table 064. After the first positioning is completed, the robotic arm grabs the panel 005 to be laid from the positioning table 064 and places it at the position of the target stiffening truss 003. By pre-positioning, the laying quality and laying efficiency can be greatly improved.

[0165] Optionally, the panel laying station may further include a chain conveyor table and a vision positioning device. The vision positioning device is located at one end of the chain conveyor table. The chain conveyor table is used to convey the first wall panel, which is equivalent to the function of the conveying mechanism 077. When the first wall panel is coated with glue and conveyed to the panel laying station, first, the vision positioning device performs vision positioning on a corner of the first wall panel to determine the position of the first wall panel. At the same time, the robotic arm uses the gripping tool head to grab the panel 005 to be laid from the storage table 062 and place it on the positioning table 064. After the exact position of the panel 005 is determined through the positioning table 064 once, the robotic arm grabs the panel 005 again and lays it at the position to be laid of the first wall panel. Through the robotic arm's cyclic gripping - first positioning - laying, finally, the panel 005 on the upper surface of the first wall panel is laid to complete the formation of the second wall panel.

[0166] Optionally, the panel 005 to be laid can be a cement board or a panel 005 made of other materials.

[0167] Please refer to Figure 20 for the schematic structural diagram of the nailing mechanism 072 shown.

[0168] Specifically, the nailing mechanism 072 may include a truss and a plurality of nailing heads. The plurality of nailing heads are installed on the truss in a preset distribution manner. The truss drives the plurality of nailing heads to adjust their positions in the first direction 007 and / or the second direction 009. The nailing heads are used to fix the stiffening truss 003 and the panel 005 in the second wall panel.

[0169] After the panel 005 is paved, the second wall panel is transported to the nailing station by the conveying mechanism 077. First, the second wall panel is positioned by the proximity switch installed on the conveying table, and then the panel 005 is drilled and nailed by the nailing mechanism 072. The truss of the nailing mechanism 072 can ensure that the nail head moves along the horizontal X direction and Y direction. When the movement is in place, multiple nail heads can move vertically to ensure the vertical nailing operation.

[0170] Each station is arranged in sequence to facilitate the transportation of the first wall panel or the second wall panel to the next process. In an alternative embodiment, a conveying mechanism 077 may further be included. The conveying mechanism 077 is sequentially arranged on the workbench along the forming process of the precast wall panel production line 100. The first wall panel is sequentially transported to the steel bar threading station 020, the flipping station, and the panel paving station through the conveying mechanism 077.

[0171] Optionally, please refer to Figure 21 , which shows the structural schematic diagram of the conveying mechanism 077.

[0172] The conveying mechanism 077 includes multiple groups of rollers fixedly installed on the workbench. The multiple groups of rollers are arranged side by side, and each row is provided with multiple rollers extending in the same direction. The rollers are rotatably arranged on the base 0221 through bearings. The rotation directions of all the rollers are the same, and the first wall panel will move forward as the rollers rotate.

[0173] The precast wall panel production line 100 provided by the embodiment of the present application is a full-automatic production line. Multiple stations are arranged in sequence, and flow-line operation can be realized, which can improve production efficiency while ensuring production quality.

[0174] In the embodiment of the present application, a precast wall panel production process is also provided. Please refer to Figure 22 , which shows the flow schematic diagram of the precast wall panel production process.

[0175] Specifically, the precast wall panel production process may include the following steps:

[0176] S101. Assemble at least two square through columns 002 and multiple stiffening trusses 003 to form the first wall panel, and weld the first surface of the first wall panel.

[0177] This step can be carried out at the assembly and welding station 010 of the precast wall panel production line 100. At least two square tube columns 002 and multiple stiffening trusses 003 are assembled and fixed according to the designed structure by the assembly fixture 012. Specifically, two of the at least two square tube columns 002 are located on the outermost sides and both extend along the second direction 009. The multiple stiffening trusses 003 are arranged at intervals along the second direction 009 between the two square tube columns 002, and each stiffening truss 003 extends along the first direction 007. After the square tube columns 002 and the stiffening trusses 003 are arranged according to the product design, the clamping mechanism 019 is used to clamp and fix the stiffening trusses 003. Finally, the connection between the stiffening trusses 003 and the square tube columns 002 is welded and fixed by the first welding piece.

[0178] Note that at this time, most welding can only be carried out at the position on the first surface (upper surface) of the square tube column 002, and the connection at the lower position (second surface) is blocked and not easily welded. However, through the welding at the upper position, the stiffening truss 003 and the square tube column 002 can also be preliminarily connected into a whole, that is, the first wall panel.

[0179] After welding is completed, the clamping mechanism 019 releases the stiffening truss 003, and the welded first wall panel is hoisted by a gantry crane to the steel bar threading station 020 for the steel bar 004 threading process.

[0180] S105. Thread the steel bar 004 into the steel bar threading hole of the first wall panel and weld the connection between the steel bar 004 and the first wall panel.

[0181] Each stiffening truss 003 has been prefabricated with steel bar threading through holes before assembly. When multiple stiffening trusses 003 are assembled into the first wall panel, the multiple through holes of the multiple stiffening trusses 003 are aligned to form multiple steel bar threading holes. In other words, each stiffening truss 003 has multiple through holes along the length direction. When multiple stiffening trusses 003 are arranged at intervals along the second direction 009 in sequence, the multiple through holes on the multiple stiffening trusses 003 form a multi-row and multi-column arrangement. The multiple through holes in each column are located on the same straight line and jointly form the steel bar threading holes.

[0182] This step can be carried out at the steel bar threading station 020 of the precast wall panel production line 100, and an alignment mechanism 022 is used to assist the steel bar 004 to pass through the steel bar threading holes. Specifically, while extending along the second direction 009, the alignment mechanism 022 is arranged on a plurality of stiffening trusses 003, and a plurality of alignment components 0223 in the alignment mechanism 022 are respectively located in front of the through holes for threading a plurality of steel bars 004. The small end of the funnel-shaped through hole is close to the through hole, and the large end is arranged away from the through hole. When threading, the steel bar 004 passes through the funnel-shaped through hole of the end alignment component 0223 and then sequentially passes through the through holes on the first stiffening truss 003, and then sequentially passes through the through holes on the second stiffening truss 003 with the help of the second alignment component 0223, and so on until passing through all the through holes of the stiffening trusses 003.

[0183] Optionally, the alignment mechanism 022 can be one or multiple. When the alignment mechanism 022 is one, first install the alignment mechanism 022 in front of the first through hole of a plurality of stiffening trusses 003. After passing the steel bar 004 through all the first through holes of the stiffening trusses 003 by the above method, then disassemble the alignment mechanism 022, adjust it in front of the second through hole of the plurality of stiffening trusses 003, and thread the steel bar 004, and so on until all the through holes are threaded with the steel bar 004. When the alignment mechanism 022 is multiple, first install the multiple alignment mechanisms 022 in front of the multiple through holes of the multiple stiffening trusses 003 respectively, and pass the multiple steel bars 004 through each through hole of all the stiffening trusses 003 respectively by the above method, then the threading of the steel bar 004 can be completed.

[0184] After the threading is completed, weld the first surface at the connection of the steel bar 004 and the stiffening truss 003 to fix the steel bar 004 and the stiffening truss 003.

[0185] S108. Flip the first wall panel by 180° and weld the second surface of the first wall panel.

[0186] Since only the connections of the square through columns 002, the stiffening trusses 003, and the steel bars 004 on the first surface of the first wall panel are welded at the assembly and welding station 010 and the steel bar threading station 020, the welding effect is not firm and the stability of the first wall panel is insufficient. Therefore, it is necessary to flip the first wall panel by 180°, and then weld the connections of the square through columns 002, the stiffening trusses 003, and the steel bars 004 on the second surface of the first wall panel to make the first wall panel a stable whole.

[0187] The first wall panel can be flipped by 180° at the flipping station of the precast wall panel production line 100. The flipping mechanism 041 is used to flip the first wall panel, and the conveying mechanism 077 cooperates with the flipping mechanism 041. The conveying mechanism 077 conveys the first wall panel into the installation cavity of the clamping assembly 043 of the flipping mechanism 041. The clamping cylinder 0437 acts to fix the first wall panel. The horizontal moving mechanism 0412 and the vertical moving mechanism 0413 cooperate to move. While the horizontal moving mechanism 0412 drives the clamping assembly 043 to move horizontally, the vertical moving mechanism 0413 drives the clamping assembly 043 to rise vertically, so that the clamping assembly 043 fixed with the first wall panel changes from the horizontal state to the vertical state. Then, the horizontal moving mechanism 0412 drives the clamping assembly 043 to continue to move horizontally, and at the same time, the vertical moving mechanism 0413 drives the clamping assembly 043 to descend vertically, so that the first wall panel in the vertical state returns to the horizontal state again. At this time, the flipping of the first wall panel is completed.

[0188] Optionally, the flipping station can include a first flipping station 040 and a second flipping station 080. The first flipping station 040 can be located at the next station of the steel bar passing-through station 020 and is used to turn over the first wall panel. The second flipping station 080 is located at a position that needs to be flipped later, which is specifically determined according to actual requirements.

[0189] After the turning over is completed, the second surface of the first wall panel is located above and the first surface is located below.

[0190] Welding the second surface of the first wall panel can be carried out at the reverse welding station 045 of the precast wall panel production line 100. The first wall panel is conveyed to the reverse welding station 045 through the conveying mechanism 077. The second welding parts in the reverse welding station 045 are used to weld the connection parts of the stiffening truss 003 and the square tube column 002 and the connection parts of the steel bar 004 and the stiffening truss 003 on the second surface, so that the steel bar 004, the stiffening truss 003, and the square tube column 002 are firmly fixed.

[0191] S125. Lay the panel 005 on the second surface of the first wall panel to form the second wall panel.

[0192] This step can be carried out at the panel laying station of the precast wall panel production line 100, and the laying mechanism 065 is used to lay the panel 005.

[0193] The robotic arm in the laying mechanism 065 first grabs the panel 005 located on the storage table 062 and places it on the positioning table 064 for the first positioning. After positioning, it grabs the panel 005 on the positioning table 064 again and lays it on the second surface of the target stiffening truss 003 of the first wall panel, and so on until the second surface of the first wall panel is completely laid.

[0194] Optionally, the panel paving station may include a first paving station 060 and a second paving station 084. The first paving station 060 may be located at the next station after the flipping station and is used for laying the second surface of the firmly welded first wall panel. The second paving station 084 is located at the position where the panel 005 needs to be laid on the first surface subsequently, which is determined according to actual requirements.

[0195] In an alternative embodiment, please refer to Figure 23 , which shows a schematic flow diagram of the assembly and welding process in the precast wall panel production process.

[0196] Assemble at least two square tube columns 002 and multiple stiffening trusses 003 to form a first wall panel. Welding the first surface of the first wall panel may include the following steps:

[0197] S1011: Provide at least two square tube columns 002. The at least two square tube columns 002 are arranged oppositely, and the square tube columns 002 extend along the second direction 009.

[0198] S1013: Provide multiple stiffening trusses 003. The multiple stiffening trusses 003 are sequentially arranged at intervals along the second direction 009 between the at least two square tube columns 002, and the multiple stiffening trusses 003 extend along the first direction 007.

[0199] S1015: Fix the square tube columns 002 and the multiple stiffening trusses 003.

[0200] S1017: Weld the connection points of the square tube columns 002 and the stiffening trusses 003.

[0201] In an alternative embodiment, please refer to Figure 24 , which shows a schematic flow diagram of the steel bar threading process in the precast wall panel production process.

[0202] Thread steel bars 004 through the steel bar threading holes in the first wall panel. Welding the connection points of the steel bars 004 and the first wall panel may include the following steps:

[0203] S1051: Provide multiple steel bars 004. The multiple stiffening trusses 003 in the first wall panel form multiple steel bar threading holes, and the multiple steel bars 004 are respectively threaded through the multiple steel bar threading holes.

[0204] S1053: Weld the connection points of the steel bars 004 and the first wall panel.

[0205] In an alternative embodiment, please refer to Figure 25 , which shows a schematic flow diagram of the panel paving process in the precast wall panel production process.

[0206] Laying the panel 005 on the second surface of the first wall panel to form a second wall panel may include the following steps:

[0207] S1251. Pre-position the panel 005 to be laid before laying.

[0208] S1253. Grab the panel 005 to be laid after pre-positioning and lay it at the position of the target stiffening truss 003.

[0209] It can be understood that the panel 005 here can include cement boards and panels 005 made of other materials.

[0210] In order to increase the stability of the panel 005 after laying, a gluing station can also be set before the station for laying the panel 005. Further, please refer to Figure 26 , which shows the schematic flow chart of the precast wall panel production process.

[0211] Specifically, between step S108 and step S125, it can also include:

[0212] S122. Apply glue to the second surface of the stiffening truss 003 in the first wall panel.

[0213] This step can be carried out at the gluing station of the precast wall panel production line 100, which is located between the flipping station and the panel laying station. The gluing mechanism 052 is used to apply glue to the second surface of all the stiffening trusses 003.

[0214] The gluing mechanism 052 needs to be assisted by the conveying mechanism 077. A plurality of glue guns are provided on the glue gun, and the plurality of glue guns are arranged at intervals in sequence along the second direction 009. The plurality of glue guns correspond to the plurality of stiffening trusses 003 one by one. The glue gun is installed on the adjusting mechanism, and the adjusting mechanism drives the glue gun to move up and down so that the glue gun head is close to or away from the upper part of the stiffening truss 003; the adjusting mechanism also drives the glue gun to swing horizontally left and right. When the adjusting mechanism drives the glue gun to swing left and right, the conveying mechanism 077 drives the first wall panel to move forward, thereby realizing that a plurality of glue gun heads simultaneously apply snake-shaped or Z-shaped glue on a plurality of stiffening trusses 003, which is convenient for the subsequent panel 005 to be adhesively laid on the stiffening truss 003.

[0215] Optionally, the gluing station can include a first gluing station 050 and a second gluing station 082. The first gluing station 050 can be located at the next station of the flipping station and is used to apply glue to the second surface of the stiffening truss 003 of the first wall panel with firm welding, which is convenient for laying the panel 005 in the next process. The second gluing station 082 is located at the previous position before the panel 005 needs to be laid on the first surface subsequently, and is specifically determined according to actual requirements.

[0216] When the panel 005 is laid on the second surface of the first wall panel to form the second wall panel, in order to improve the stability of the panel 005 in the second wall panel. Further, please refer toFigure 27 , which is a schematic flow diagram of the precast wall panel production process.

[0217] After step S125, it may further include:

[0218] S126. Nail and fix the panel 005 and the stiffening truss 003 of the second wall panel.

[0219] This step can be carried out at the nailing station of the precast wall panel production line 100, after the panel laying station. The nailing mechanism 072 is used to drill holes and nail the entire second surface of the panel 005 and the stiffening truss 003.

[0220] S127. Repair nails at the positions where nails are missing in the second wall panel.

[0221] Optionally, a nail repair station can be set up after the nailing station. The conveying mechanism 077 conveys the second wall panel to the nail repair station, and manual nailing can be used.

[0222] S128. Flip the second wall panel by 180°.

[0223] When the panel 005 laying and nailing operations of the second wall panel are completed, the second wall panel needs to be flipped by 180° again to facilitate operations on the first surface of the second wall panel. This step can be carried out at the second flipping station 080 of the precast wall panel production line 100. The second flipping station 080 is located after the nail repair station, and the flipping mechanism 041 is also used to flip the second wall panel.

[0224] S129. Apply glue to the first surface of the stiffening truss 003 in the second wall panel.

[0225] When the second wall panel is flipped, the second surface after laying the panel 005 will be turned to the bottom, and the first surface without laying the panel 005 will be turned to the top. The above-mentioned equipment and process methods are used to apply glue to the first surface of the stiffening truss 003 in the second wall panel. The specific gluing process can refer to the above description and will not be elaborated here.

[0226] S130. Lay the panel 005 on the first surface of the second wall panel to form the third wall panel.

[0227] Lay the panel 005 on the first surface of the stiffening truss 003 of the second wall panel after gluing is completed to form the third wall panel. Among them, the specific process of laying the panel 005 can refer to the above description and will not be elaborated here.

[0228] S131. Nail and fix the panel 005 and the stiffening truss 003 of the third wall panel.

[0229] After the second wall panel completes the laying of the panel 005 to form the third wall panel, drilling and nailing can be carried out on the first surface of the third wall panel to fixedly connect the panel 005 and the stiffening truss 003 at the first surface. Among them, the specific process of nailing can refer to the above description and will not be elaborated here.

[0230] S132. Repair the missing nails at the positions in the third wall panel.

[0231] After the overall nailing is completed, in order to avoid the phenomenon of missing nails or poorly nailed nails, a nail repair station can be set up to perform manual nail repair on the first surface.

[0232] Finally, a quality inspection station 089 can also be set up to perform quality inspection on the external dimensions of the third wall panel using a vision camera at the quality inspection station 089.

[0233] In summary, the precast wall panel production process adopts fully automated production in a pipeline manner, assembling, welding, and fixing multiple wall panel components such as the square tube column 002, the stiffening truss 003, the steel bar 004, and the panel 005, and finally forming the precast wall panel 001.
