[0127] The following is a detailed introduction to the prefabricated wall panel production line 100 provided in an embodiment of the present application.

[0128] Please refer to Figure 2 , which is a schematic diagram of the structure of the assembly fixture in the assembly welding station 010. The assembly fixture 012 is used to assemble and fix at least two square columns 002 and a plurality of stiffening trusses 003 according to the designed structure to form a prefabricated wall panel 001 frame.

[0129] The assembly fixture 012 may include a bracket 014, a support platform 016, and a clamping mechanism 019. The bracket 014 is used as a support structure to support the support platform 016 and the wall panel components to be prefabricated. The bracket 014 has an assembly area, and the support platform 016 is located in the assembly area. The support platform 016 is slidably installed on the bracket 014 along the first direction 007. The support platform 016 is used to support the wall panel components to be prefabricated, such as the square column 002 and the stiffening truss 003. The stiffening truss 003 is located between the two outermost square columns 002. There are multiple stiffening trusses 003, and the multiple stiffening trusses 003 are arranged in parallel and extend along the first direction 007.

[0130] The square column 002 and the stiffening truss 003 to be assembled are placed according to the pre-designed structure. After the placement is completed, the stiffening truss 003 is clamped by the clamping mechanism 019. The clamping mechanism 019 is installed on the support platform 016 and extends along the second direction 009. The clamping mechanism 019 is used to cooperate with multiple stiffening trusses 003 to clamp or release multiple stiffening trusses 003 at the same time.

[0131] Please refer to Figure 2 and Figure 3 , Figure 3 The figure shows a structural schematic diagram of a support platform provided with a clamping mechanism for assembling prefabricated wall panel components.

[0132] Specifically, the bracket 014 includes at least two frame bodies arranged in parallel, each frame body extends along the first direction 007, and adjacent frame bodies are arranged at intervals to form an assembly area.

[0133] In an embodiment of the present application, two frames can be selected and fixed on a workbench. The distance between the two frames should meet the conventional height requirements of the prefabricated wall panels 001. The ends of the support platform 016 are respectively overlapped on the frames and can be slidably connected along a first direction 007 relative to the two frames.

[0134] Please refer to Figure 3 The support platform 016 may include a first support column 0162 and a second support column 0165 located on both sides of the first support column 0162, the first support column 0162 and the second support column 0165 both extend along the second direction 009, and the clamping mechanism 019 is installed on both sides of the first support column 0162, and the clamping mechanism 019 is used to clamp the multiple stiffening trusses 003 overlapped on the first support column 0162.

[0135] Optionally, the number of first support columns 0162 can be multiple, and the multiple first support columns 0162 are sequentially spaced along the first direction 007; the number of second support columns 0165 is two, and the two second support columns 0165 are located at the outermost side, and the width of the prefabricated wall panel 001 is determined by the distance between the two second support columns 0165. The two second support columns 0165 are used to support the outermost square column 002 of the prefabricated wall panel 001, and the multiple first support columns 0162 are used to support multiple stiffening trusses 003 and / or square columns 002, and the multiple stiffening trusses 003 are sequentially spaced along the second direction 009.

[0136] It should be noted that when the prefabricated wall panel 001 is a whole wall, the prefabricated wall panel 001 includes two outermost square columns 002 and a plurality of stiffening trusses 003 located in the middle. In this case, the second support column 0165 supports the two outermost square columns 002, and the first support column 0162 supports the plurality of stiffening trusses 003.

[0137] When the prefabricated wall panel 001 is a wall panel including door openings and / or window openings, Figure 3 In the case shown, the prefabricated wall panel 001 includes two outermost square columns 002, square columns 002 located at the side of the door opening and / or window opening, and stiffening trusses 003 located between the square columns 002. In this case, the second support column 0165 supports the two outermost square columns 002, and the first support column 0162 supports multiple stiffening trusses 003 and / or square columns 002, which depends on the actual wall panel design. That is, the prefabricated component located between the two outermost square columns 002 is supported by the first support column 0162, and the two outermost square columns 002 are supported by the second support column 0165.

[0138] There are multiple clamping mechanisms 019 , and clamping mechanisms 019 are provided on both sides of each first support column 0162 .

[0139] The clamping mechanism 019 on each side of the first support column 0162 is a linkage structure, which can simultaneously clamp or release multiple stiffening trusses 003. When the stiffening trusses 003 and the square column 002 are placed on the support platform 016 and positioned, they can be clamped simultaneously through the clamping mechanism 019, which not only makes the positioning accurate but also improves the assembly efficiency.

[0140] Please refer to Figure 4 and Figure 5 , Figure 4 The figure shows a schematic diagram of the structure in which the clamping mechanism is arranged on both sides of the first support column. Figure 5 Shown is a partial schematic diagram of the clamping mechanism.

[0141] Specifically, the clamping mechanism 019 may include a quick-release plate 0191, a plurality of fixing parts 0192 and a linkage assembly, wherein the quick-release plate 0191 is fixedly mounted on the side wall of the first support column 0162 of the support platform 016, and the plurality of fixing parts 0192 are fixed to the quick-release plate 0191 at intervals in sequence along the second direction 009, and the plurality of fixing parts 0192 are located on the same straight line, and the linkage assembly is slidably arranged on the plurality of fixing parts 0192 along the second direction 009. The linkage assembly includes a plurality of movable parts 0197, and the plurality of movable parts 0197 are arranged in one-to-one correspondence with the plurality of fixed parts 0192. When the linkage assembly moves along the second direction 009 relative to the plurality of fixed parts 0192, the plurality of movable parts 0197 move synchronously, and the corresponding fixed parts 0192 and movable parts 0197 form a group. A clamping space for clamping the stiffening truss 003 is formed between the fixed parts 0192 and the movable parts 0197 in the same group. The plurality of movable parts 0197 are linked to allow the plurality of movable parts 0197 to approach or move away from the corresponding fixed parts 0192 at the same time.

[0142] The fixing member 0192 and the linkage assembly are detachably mounted on the side wall of the first support column 0162 via a quick-release plate 0191 , so that the clamping mechanism 019 as a whole can be conveniently installed or removed from the first support column 0162 .

[0143] Since the stiffening trusses 003 are arranged on the first support column 0162, the clamping mechanism 019 is installed on the side wall of the first support column 0162. In order to better clamp the plurality of stiffening trusses 003 and not interfere 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 from the upper surface of the first support column 0162, the plurality of fixing members 0192 are fixed to the quick release plate 0191 and at least partially protrude from the upper surface of the first support column 0162, and the plurality of movable members 0197 in the linkage assembly and the plurality of fixing members 0192 are arranged alternately 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 from the upper surface of the first support column 0162.

[0144] The movable member 0197 and the fixed member 0192 in the same group are arranged relative to each other to form a clamping space. That is, by fixing the fixed member 0192, the movable member 0197 moves closer to or away from the fixed member 0192, thereby clamping or loosening the stiffening truss 003.

[0145] In order to enable multiple movable parts 0197 to move synchronously, optionally, the linkage assembly may also include a linkage rod 0198, which is slidable along the second direction 009 and passes through the multiple fixed parts 0192. The multiple movable parts 0197 are fixed on the linkage rod 0198 at intervals in sequence along the second direction 009. The linkage rod 0198 drives the multiple movable parts 0197 to move synchronously to approach or move away from the corresponding fixed parts 0192.

[0146] like Figure 5 As shown, the linkage rod 0198 is inserted through all the fixing members 0192. After the insertion, the movable members 0197 and the fixing members 0192 are arranged alternately and sequentially, 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, multiple stiffening trusses 003 can be clamped and fixed at the same time or released synchronously.

[0147] Please continue to refer to Figure 5 As shown, the number of linkage rods 0198 is at least two, and 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, which is used to clamp the stiffening truss 003. A through hole can be opened on the other ear, and the number of the through holes is the same as the number of linkage rods 0198, and the positions correspond one to one, and the linkage rods 0198 can slide through the through holes, and at least two linkage rods 0198 are fixedly connected at the ends to form a whole.

[0148] By providing at least two linkage rods 0198 that are fixedly connected, and at least two linkage rods 0198 that are correspondingly inserted into the insertion holes, the linkage assembly can be prevented from rotating relative to the fixed member 0192. In other words, the linkage assembly has only the freedom to slide along the second direction 009 relative to the fixed member 0192, and during the sliding process, the movable member 0197 of the linkage assembly approaches or moves away from the fixed member 0192 that matches it.

[0149] In the above structure, the movable part 0197 is also provided with holes, the number of holes provided on the movable part 0197 is the same as the number of the linkage rod 0198, and the positions correspond one to one, and the movable part 0197 and the linkage rod 0198 are relatively fixedly connected.

[0150] In other optional embodiments, fasteners may also be included. During installation, the linkage rod 0198 passes through the fixed member 0192, the fasteners, and the movable member 0197 in sequence until all the fixed members 0192 and the movable member 0197 are installed and the position of the movable member 0197 is determined, and then the movable member 0197 and the linkage rod 0198 are fixed by the fasteners, which is convenient for installation and operation.

[0151] Furthermore, in order to enhance the clamping effect of the movable member 0197 and the fixed member 0192 on the stiffening truss 003, an abutment plate 0196 may be elastically provided on the opposite side of the movable member 0197 and / or the fixed member 0192. Figure 5 A contact plate 0196 is elastically provided on one side of the movable part 0197 close to the fixed part 0192 in the same group. The contact plate 0196 and the movable part 0197 are connected by a spring. The contact plate 0196 and the fixed part 0192 are used to contact the two sides of the stiffening truss 003.

[0152] Furthermore, the clamping mechanism 019 may also 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 be a driving cylinder, and 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.

[0153] In order to facilitate the disassembly, assembly and maintenance of the clamping mechanism 019, optionally, the driving member can be used to individually control the linkage components in each clamping mechanism 019. During the disassembly, assembly and maintenance process, the quick-release plate 0191 can be used for quick disassembly, which is convenient for maintenance. Of course, in other optional embodiments, all clamping mechanisms 019 can use a set of driving members, and a set of driving members is used to simultaneously control the movement of all linkage components. This application does not limit the specific implementation method, which depends on actual needs.

[0154] Optionally, in order to facilitate positioning of the square column 002 during assembly, a positioning protrusion is provided on the top surface of the first support column 0162 and / or the second support column 0165 .

[0155] Matching with the positioning protrusion, a process hole is opened at the corresponding position of the square column 002, and the positioning protrusion is used to cooperate with the process hole to position the square column 002. During operation, the square column 002 is hoisted by a crane, the process hole of the square column 002 is matched with the positioning protrusion on the support column, and the square column 002 is gradually lowered. With the help of the self-gravity of the square column 002, the cooperation of the positioning protrusion and the process hole, the positioning of the square column 002 can be achieved.

[0156] In the embodiment of the present application, the support platform 016 can be slidably mounted on the bracket 014, and the distance and position of the first support column 0162 and the second support column 0165 can be adjusted to match the prefabricated wall panel 001 to be assembled. The second support column 0165 receives the square column 002, and the first support column 0162 receives the stiffening truss 003 and the square column 002, which can be used to support the components of the prefabricated wall panel 001 to be assembled and can also be positioned. The stiffening truss 003 after positioning is fixed by the clamping mechanism 019, so that the square column 002 and all the stiffening trusses 003 are relatively fixed, which is convenient for the subsequent welding process. In a clamping mechanism 019, by installing multiple fixings 0192 and linkage components on the quick-release plate 0191, and the quick-release plate 0191 is installed on the first support column 0162, the clamping mechanism 019 can be quickly disassembled and quickly installed. By setting a plurality of fixed parts 0192 and a plurality of movable parts 0197, the fixed parts 0192 and the movable parts 0197 are arranged alternately in sequence and form a group of two, and the same group of fixed parts 0192 and movable parts 0197 corresponds to a stiffening truss 003, and the linkage rod 0198 drives the plurality of movable parts 0197 to move synchronously relative to the plurality of fixed parts 0192, so that the stiffening truss 003 can be clamped or released at the same time, which is convenient for fixing and greatly improves the fixing efficiency. It also improves the assembly efficiency during the assembly process, is easy to operate, has high assembly precision, and has a wide range of applications. It can be applied to the assembly process of prefabricated wall panels 001 of different specifications and sizes, and has strong practicality and operability.

[0157] Specifically, the steel bar threading 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 be smoothly threaded into the steel bar threading hole. The third welding part is used to weld and fix the connection between the threaded steel bar 004 and the stiffening truss 003 in the first wall panel.

[0158] Please refer to 6, which is a schematic diagram of the structure of the prefabricated wall panel 001.

[0159] Since the reinforcing trusses 003 are pre-formed with through holes, the through holes on the multiple reinforcing trusses 003 in the assembled first wall panel correspond to each other, forming multiple steel bar insertion holes located on the same straight line. The steel bar insertion station 020 inserts multiple steel bars 004 into the multiple steel bar insertion holes one by one, and after the insertion is completed, the steel bars 004 and the first wall panel are welded and fixed.

[0160] When inserting the steel bars 004, the steel bars 004 are easily bent downward due to gravity. Since the reserved through holes on the stiffening trusses 003 are small, it is difficult to align the steel bars 004 with the reserved through holes on each stiffening truss 003. Manual assistance is required to align the ends of the steel bars 004 with the reserved through holes on each stiffening truss 003 in turn. This results in a low penetration efficiency of the steel bars 004, affecting the production efficiency of the prefabricated wall.

[0161] In order to improve the penetration efficiency of the steel bar 004, an alignment mechanism 022 is provided on the steel bar penetration station 020 in the prefabricated wall panel production line 100 provided in the embodiment of the present application. Figure 6 and Figure 7 , Figure 7 Shown is a schematic structural diagram of the alignment mechanism 022.

[0162] 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, the plurality of alignment components 0223 are arranged on the base 0221 in sequence and at intervals along the second direction 009, and each alignment component 0223 is used to assist the steel bar 004 in aligning with the steel bar penetration hole.

[0163] Among them, the base 0221 is mainly used to carry multiple alignment components 0223. In other words, multiple alignment components 0223 need to be installed on the base 0221, so that multiple alignment components 0223 can be moved at one time through the base 0221, so that multiple alignment components 0223 can be moved to the target position at the same time. The target position here refers to the position that can assist the steel bar 004 to align with the steel bar penetration hole.

[0164] In the present application, there are multiple alignment components 0223, and each of the multiple alignment components 0223 is used to assist the steel bar 004 in aligning with one of the steel bar penetration holes. In some embodiments, the alignment component 0223 may include: Figure 8The funnel-shaped structure shown may include a first clamp 0224 and a second clamp 0226 that match each other. When it is necessary to assist the reinforcement 004 to align with the reinforcement insertion hole, the first clamp 0224 and the second clamp 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 reinforcement insertion hole behind it. The reinforcement 004 first penetrates from the first opening at the front end of the funnel-shaped through hole, then passes out from the second opening, and then smoothly passes through the reinforcement insertion hole behind the second opening. After the reinforcement 004 has penetrated each through hole in turn, the two parts of each funnel-shaped through hole are separated from each other, and a gap is formed between the first clamp 0224 and the second clamp 0226, so that the first clamp 0224 and the second clamp 0226 can be removed from both sides of the reinforcement 004 along the gap.

[0165] In the present application, a plurality of alignment components 0223 are arranged on the base 0221 along the second direction 009, and each alignment component 0223 is used to assist the steel bar 004 in aligning with the steel bar penetration hole, so that when the steel bar 004 penetrates forward along the second direction 009, each alignment component 0223 can be used to align with the corresponding through hole in turn, thereby achieving rapid penetration of the steel bar 004 and improving processing or construction efficiency.

[0166] In some specific embodiments, the alignment mechanism 022 may further include a driving member, which is mounted on the base 0221. The driving member includes a plurality of mobile units 030 sequentially arranged at intervals along the second direction 009, each mobile unit 030 includes a first mounting portion 0301 and a second mounting portion 0303 arranged opposite to each other, and a plurality of alignment components 0223 are correspondingly mounted on the plurality of mobile units 030. The driving member controls each alignment component 0223 to move to the front of the corresponding steel bar penetration hole and / or move away from the front of the corresponding steel bar penetration hole through the mobile unit 030.

[0167] Optionally, a plurality of alignment assemblies 0223 are mounted on a plurality of mobile units 030 in a one-to-one correspondence along the second direction 009. The driving member can control the movement of the mobile unit 030. Optionally, the driving member may include a track module, at least one end of the mobile unit 030 is connected to the track module, so that the movement of the mobile unit 030 can be controlled by the track module. Alternatively, the driving member may be a cylinder module, at least one end of the mobile unit 030 is connected to the cylinder module, so that the movement of the mobile unit 030 can be controlled by the cylinder module.

[0168] In the present application, each mobile unit 030 may include a first mounting portion 0301 and a second mounting portion 0303 that are relatively arranged, and a plurality of alignment components 0223 are installed one by one on the plurality of mobile units 030, and the first mounting portion 0301 and the second mounting portion 0303 of the mobile unit 030 are controlled by a driving member to move toward or away from each other, so that the plurality of alignment components 0223 can be quickly and accurately moved to the front of the steel bar penetration hole, and the plurality of alignment components 0223 can also be quickly moved away from the front of the steel bar penetration hole.

[0169] For details, please refer to Figure 8 and Fig. 9 As shown, each alignment assembly 0223 may include a first clamping body 0224 and a second clamping body 0226 that match each other. A first alignment groove 0227 is provided on a side of the first clamping body 0224 close to the second clamping body 0226, and a second alignment groove 0229 is provided on a 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 approach each other or move 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 to each other or move away from each other. When the first clamping body 0224 and the second clamping body 0226 approach each other to close, the first alignment groove 0227 and the second alignment groove 0229 are closed to form a funnel-shaped through hole, and 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 clamp body 0224 and the second clamp body 0226 move away from each other, the first alignment groove 0227 and the second alignment groove 0229 open to form a gap for the steel bar 004 to exit, that is, there is a gap between the first clamp body 0224 and the second clamp body 0226 after opening to each other, and the width of the gap is greater than the diameter of the steel bar 004.

[0170] Specifically, before the reinforcing bar 004 is penetrated, the first clamp 0224 and the second clamp 0226 are controlled by the driving member to close each other to form a funnel-shaped through hole, thereby assisting the reinforcing bar 004 to align with the reinforcing bar penetration hole based on the funnel-shaped through hole. After the reinforcing bar 004 is penetrated, the first clamp 0224 and the second clamp 0226 are controlled by the driving member to open each other, thereby forming a gap between the first clamp 0224 and the second clamp 0226, and then the alignment assembly 0223 can be moved away from both sides of the reinforcing bar 004 along the gap.

[0171] The first alignment groove 0227 provided on the first clamp body 0224 and the second alignment groove 0229 provided on the second clamp body 0226 both include a large diameter end and a small diameter end. In the plurality of alignment components 0223, the large diameter end of each alignment component 0223 is oriented in the same direction relative to the small diameter end, and the funnel-shaped through holes formed in the plurality of alignment components 0223 are located on the same straight line, so as to facilitate the smooth insertion of the steel bars 004.

[0172] Please refer to Fig.10 , which is a schematic structural diagram of the flipping mechanism 041.

[0173] Specifically, the flip 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 move together at the same time to flip the clamping assembly 043. The clamping assembly 043 is used to install the first wall panel with the steel bar 004 penetrated. When the clamping assembly 043 is flipped, it will drive the first wall panel with the steel bar 004 penetrated to flip synchronously.

[0174] Optionally, see Fig.11 , which is a schematic diagram of the structure of the rack 0411. The rack 0411 is a rectangular frame structure, including upper and lower cross beams and longitudinal beams, the upper cross beam and the lower cross beam respectively enclose an upper rectangular frame and a lower rectangular frame, and the longitudinal beam connects 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.

[0175] Please refer to Fig.10 and Fig.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 assembly and a slider. The first transmission assembly is installed on the lower rectangular frame of the frame 0411. The first motor is connected to the first transmission assembly to drive the first transmission assembly to move. The slider is slidably arranged on the first transmission assembly along the second direction 009. The slider is hinged to the clamping assembly 043 to drive the clamping assembly 043 to move horizontally.

[0176] 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.

[0177] Please refer to Fig.10 and Fig.12 , Fig.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.

[0178] 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.

[0179] 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.

[0180] For details, please refer to Fig.12The 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 telescopically move 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, and 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, thereby fixing the first wall panel and preventing the first wall panel from sliding off during the flipping process.

[0181] Optionally, the first hinged portion 0434 of the clamping assembly 043 is hinged to the slider of the horizontal moving mechanism 0412, and the second hinged portion 0435 of the clamping assembly 043 is hinged to the sliding bracket 0415014 of the vertical moving mechanism 0413. The first hinged portion 0434 may be located at the middle position of the clamping frame 0432 along the third direction, and the second hinged portion 0435 is located at the middle position of the clamping frame 0432 along the fourth direction.

[0182] Please refer to Figures 13 to 17 , respectively, show the process of flipping the first wall panel using the flipping mechanism 041. In the initial state, the clamping assembly 043 is in a horizontal state, and the first wall panel with the steel bar 004 installed is embedded in the installation cavity of the clamping frame 0432 under the conveyance of the conveying mechanism 077, and the clamping cylinder 0437 is actuated to fix the first wall panel. The slider in the horizontal moving mechanism 0412 drives one end of the clamping assembly 043 to slide along the second direction 009, and at the same time, the sliding bracket 0415014 in the vertical moving 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 fully erected, as shown in FIG. Fig.14 and Fig.15 Then, the slider in the horizontal moving mechanism 0412 drives one end of the clamping assembly 043 to continue sliding along the second direction 009, and at the same time, the sliding bracket 0415014 in the vertical moving mechanism 0413 drives the middle 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 FIG. Fig.16 and Fig.17 At this time, the first wall panel with the steel bar 004 installed is flipped 180°, and the first wall panel slides out of the installation cavity of the clamping frame 0432 under the transportation of the transportation mechanism 077. Finally, the horizontal moving mechanism 0412 and the vertical moving mechanism 0413 are reset to return to the initial state, so as to facilitate the flipping of the next first wall panel.

[0183] The reverse welding station 045 is located downstream of the first flipping station 040 and may include a second welding member for welding and fixing the connection between the square column 002 and the stiffening truss 003 and the connection between the steel bar 004 and the stiffening truss 003 on the reverse side of the first wall panel.

[0184] Please refer to Fig.18 , which is a schematic diagram of the structure of the gluing mechanism 052.

[0185] Specifically, the glue applying mechanism 052 may include an adjustment mechanism, a glue gun, and a plurality of glue applying heads. The glue gun is mounted on the adjustment mechanism, and the plurality of glue applying heads are sequentially arranged on the glue gun at intervals, and the adjustment mechanism is mounted on a workbench. The adjustment mechanism is used to adjust the position of the glue gun in the horizontal and / or vertical direction, that is, to move the plurality of glue applying heads closer to / away from the workpiece to be glued, and the horizontal position adjustment is used for the plurality of glue applying heads to apply snake-shaped or Z-shaped glue.

[0186] Optionally, the number of glue guns is the same as the number of stiffening trusses 003 to be glued and the positions are one-to-one corresponding, and the glue guns are used to glue 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 glue gun to swing in the horizontal direction, and the vertical module drives the glue gun to move vertically.

[0187] Optionally, the spacing between each glue head can be adjusted by a tension knob to adapt to the requirements of stiffening trusses 003 with different spacings.

[0188] Furthermore, the gluing station can also include an operating table, a colloid pumping station, and a secondary pumping and pressurizing device. The operating table is provided with a controller for controlling the actions of the colloid pumping station, the secondary pumping and pressurizing device, and the gluing mechanism 052. The colloid pumping station pumps the glue into the glue gun, and then delivers it to the gluing head through the secondary pumping and pressurizing device.

[0189] At the gluing station, the gluing mechanism 052 and the conveying mechanism 077 operate simultaneously. The multiple gluing heads of the gluing 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 gluing mechanism 052 swings left and right under the action of the horizontal moving motor. When the first wall panel moves from the initial position to the panel paving station, snake-shaped or Z-shaped gluing is completed on each stiffening truss 003, which is convenient for the next paving operation.

[0190] Please refer to Fig.19 , shown is a schematic diagram of the structure of the laying mechanism 065.

[0191] Specifically, the laying mechanism 065 may include a robotic arm, a grabbing tool head is provided at the power output end of the robotic arm, and the grabbing tool head is used to grab the panel 005 to be laid.

[0192] Optionally, the panel to be laid 005 is arranged on one side of the conveying mechanism 077, and the robot arm is used to grab the panel to be laid 005 and lay it on the target stiffening truss 003 of the first wall panel.

[0193] Furthermore, the panel laying station may also include a storage table 062 and a positioning table 064. 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 grabbing tool head of the robot arm and the panel 005 to be laid. The robot 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 completing the positioning once, the panel 005 to be laid is grabbed from the positioning table 064 and placed at the target stiffening truss 003 position. The laying quality and laying efficiency can be greatly improved through pre-positioning.

[0194] Optionally, the panel paving station may also include a plate chain conveyor table and a visual positioning device. The visual positioning device is located at one end of the plate chain conveyor table, and the plate chain conveyor table is used to convey the first wall panel, which is equivalent to the function of the conveying mechanism 077. After the first wall panel is coated with glue and conveyed to the panel paving station, the visual positioning device first visually locates a corner of the first wall panel to determine the position of the first wall panel. At the same time, the robot arm uses the grabbing 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 positioning table 064 determines the precise position of the panel 005, the robot arm grabs the panel 005 again and paves it to the position to be laid of the first wall panel. Through the robot arm's cycle of grabbing, positioning once, and paving, the panel 005 on the upper surface of the first wall panel is finally paved to form the second wall panel.

[0195] Optionally, the panel 005 to be laid can be a panel 005 of a cement board or other materials.

[0196] Please refer to Fig. 20 , which is a schematic diagram of the structure of the nailing mechanism 072.

[0197] 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, and the truss drives the plurality of nailing heads to adjust positions in the first direction 007 and / or the second direction 009, and the nailing heads are used to fix the reinforcing truss 003 and the panel 005 in the second wall panel.

[0198] After the panel 005 is laid, the second wall panel is transported to the nailing station through the conveying mechanism 077. First, the second wall panel is positioned by the proximity switch installed on the conveying platform, 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 nailing head moves in the horizontal X direction and Y direction. When moved into place, multiple nailing heads can move vertically to ensure vertical nailing operations.

[0199] Each station is arranged in sequence to facilitate the conveyance of the first wall panel or the second wall panel to the next process. In other optional embodiments, a conveying mechanism 077 may also be included. The conveying mechanism 077 is sequentially arranged on the workbench along the forming process of the prefabricated wall panel production line 100. The first wall panel is sequentially transferred to the steel bar threading station 020, the turning station and the panel paving station through the conveying mechanism 077.

[0200] Optionally, see Fig.21 , shown is a schematic structural diagram of the conveying mechanism 077.

[0201] The conveying mechanism 077 includes multiple groups of rollers fixedly mounted on a workbench. The multiple groups of rollers are arranged side by side. Each row is provided with multiple rollers extending in the same direction. The rollers are rotatably arranged on a base 0221 through bearings. All rollers rotate in the same direction. The first wall panel will move forward with the rotation of the rollers.

[0202] The prefabricated wall panel production line 100 provided in the embodiment of the present application is a fully automatic production line, in which a plurality of workstations are arranged in sequence, and assembly line operation can be realized, thereby improving production efficiency while ensuring production quality.

[0203] The present application also provides a prefabricated wall panel production process, please refer to Fig. 22 , shown is a schematic diagram of the process of prefabricated wall panel production process.

[0204] Specifically, the prefabricated wall panel production process may include the following steps:

[0205] S101, assembling at least two square columns 002 and a plurality of stiffening trusses 003 to form a first wall panel, and welding a first surface of the first wall panel.

[0206] This step can be performed at the assembly welding station 010 of the prefabricated wall panel production line 100, and at least two square tube columns 002 and multiple stiffening trusses 003 are assembled and fixed according to the design structure by the assembly fixture 012. Specifically, two of the at least two square tube columns 002 are located at the outermost side and extend along the second direction 009, and multiple stiffening trusses 003 are arranged in sequence between the two square tube columns 002 along the second direction 009, 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 stiffening trusses 003 are clamped and fixed by the clamping mechanism 019. Finally, the connection between the stiffening trusses 003 and the square tube columns 002 is welded and fixed by the first welding piece.

[0207] Note that welding can only be done on the first surface (upper surface) of the square column 002, and the connection (second surface) at the lower position is blocked and difficult to weld. However, by welding at the upper position, the stiffening truss 003 and the square column 002 can also be preliminarily connected to form a whole, that is, the first wall panel.

[0208] After welding is completed, the clamping mechanism 019 releases the stiffening truss 003, and the first wall panel after welding is hoisted to the steel bar threading station 020 by a crane to carry out the steel bar 004 threading process.

[0209] S105, inserting steel bar 004 into the steel bar insertion hole of the first wall panel, and welding the connection between steel bar 004 and the first wall panel.

[0210] Each stiffening truss 003 has prefabricated through holes for the reinforcement bars 004 before assembly. When multiple stiffening trusses 003 are assembled into a first wall panel, multiple through holes of multiple stiffening trusses 003 are aligned to form multiple reinforcement bars through holes. In other words, each stiffening truss 003 has multiple through holes along the length direction. When multiple stiffening trusses 003 are sequentially arranged at intervals along the second direction 009, multiple through holes on multiple stiffening trusses 003 form a multi-row and multi-column arrangement. Multiple through holes in each column are located on the same straight line and together form reinforcement bars through holes.

[0211] This step can be performed at the steel bar threading station 020 of the prefabricated wall panel production line 100, and an alignment mechanism 022 is used to assist the steel bar 004 in being threaded into the steel bar threading hole. Specifically, the alignment mechanism 022 is arranged on multiple stiffening trusses 003 while extending along the second direction 009, and multiple alignment components 0223 in the alignment mechanism 022 are arranged one by one in front of multiple steel bar 004 threading holes, with the small end of the funnel-shaped through hole close to the through hole and the large end away from the through hole. During threading, the steel bar 004 passes through the funnel-shaped through hole of the end alignment component 0223 and then passes through the through hole on the first stiffening truss 003 in sequence, and then passes through the through hole on the second stiffening truss 003 in sequence with the help of the second alignment component 0223, and so on, until it passes through all the through holes of the stiffening trusses 003.

[0212] Optionally, the alignment mechanism 022 can be one or more. When there is one alignment mechanism 022, the alignment mechanism 022 is first installed in front of the first through hole of the plurality of stiffening trusses 003, and the steel bars 004 are passed through the first through holes of all the stiffening trusses 003 using the above method, and then the alignment mechanism 022 is disassembled and adjusted to the second through hole of the plurality of stiffening trusses 003 to pass through the steel bars 004, and so on until all the through holes are passed through with the steel bars 004. When there are multiple alignment mechanisms 022, the multiple alignment mechanisms 022 are first installed one by one in front of the multiple through holes of the plurality of stiffening trusses 003, and the multiple steel bars 004 are passed through each through hole of all the stiffening trusses 003 using the above method, and the passing of the steel bars 004 can be completed.

[0213] After the threading is completed, the first surface welding is performed on the steel bar 004 and the reinforcing truss 003 at the connection to fix the steel bar 004 and the reinforcing truss 003.

[0214] S108, turning the first wall panel 180 degrees, and welding the second surface of the first wall panel.

[0215] Since only the connections among the square columns 002, the reinforcing trusses 003 and the reinforcing bars 004 on the first surface of the first wall panel are welded at the assembly welding station 010 and the reinforcing bar threading station 020, the welding effect is not strong and the stability of the first wall panel is insufficient. Therefore, it is necessary to flip the first wall panel 180° and then weld the connections among the square columns 002, the reinforcing trusses 003 and the reinforcing bars 004 on the second surface of the first wall panel to make the first wall panel a stable whole.

[0216] The first wall panel can be flipped 180° at the flipping station of the prefabricated wall panel production line 100. The first wall panel is flipped by the flipping mechanism 041, and the conveying mechanism 077 cooperates with the flipping mechanism 041. The conveying mechanism 077 is used to convey the first wall panel to the installation cavity of the clamping assembly 043 of the flipping mechanism 041. The clamping cylinder 0437 is actuated to fix the first wall panel. The horizontal moving mechanism 0412 and the vertical moving mechanism 0413 cooperate to move. The horizontal moving mechanism 0412 drives the clamping assembly 043 to move horizontally while 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 is changed from a horizontal state to a 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, and the flipping of the first wall panel is completed.

[0217] Optionally, the turning station may include a first turning station 040 and a second turning station 080. The first turning station 040 may be located at the next station of the steel bar threading station 020, and is used to turn over the first wall panel. The second turning station 080 is located at a position that needs to be turned over later, depending on actual needs.

[0218] After the turning over is completed, the second surface of the first wall panel is located at the upper side, and the first surface is located at the lower side.

[0219] Welding of the second surface of the first wall panel can be carried out at the reverse welding station 045 of the prefabricated wall panel production line 100. The first wall panel is transported to the reverse welding station 045 by the conveying mechanism 077, and the second surface is welded at the connection between the stiffening truss 003 and the square column 002, and at the connection between the steel bar 004 and the stiffening truss 003 by the second welding part in the reverse welding station 045, so as to firmly fix the steel bar 004, the stiffening truss 003 and the square column 002.

[0220] S125. Lay panel 005 on the second surface of the first wall panel to form a second wall panel.

[0221] This step can be performed at the panel laying station of the prefabricated wall panel production line 100, using the laying mechanism 065 to lay the panel 005.

[0222] The robotic arm in the laying mechanism 065 first grabs the panel 005 on the storage table 062 and places it on the positioning table 064 for positioning. After positioning, the robotic arm 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 laid.

[0223] Optionally, the panel laying station may include a first laying station 060 and a second laying station 084. The first laying station 060 may be located at the next station of the flipping station, and is used to lay the second surface of the first wallboard that is firmly welded. The second laying station 084 is located at a position where the panel 005 needs to be laid on the first surface later, depending on actual needs.

[0224] In an alternative embodiment, please refer to Fig.23 , which is a schematic flow chart of the assembly and welding process in the prefabricated wall panel production process.

[0225] Assembling at least two square columns 002 and a plurality of stiffening trusses 003 to form a first wall panel, and welding a first surface of the first wall panel may include the following steps:

[0226] S1011 , providing at least two square tube pillars 002 , wherein the at least two square tube pillars 002 are disposed opposite to each other and extend along a second direction 009 .

[0227] S1013 , providing a plurality of stiffening trusses 003 , wherein the plurality of stiffening trusses 003 are sequentially arranged between at least two square columns 002 at intervals along the second direction 009 , and the plurality of stiffening trusses 003 extend along the first direction 007 .

[0228] S1015. Fix the square column 002 and the plurality of stiffening trusses 003.

[0229] S1017, welded connection between square column 002 and stiffening truss 003.

[0230] In an alternative embodiment, please refer to Fig.24 , shown is a schematic flow chart of the steel bar threading process in the prefabricated wall panel production process.

[0231] Inserting the steel bar 004 into the steel bar insertion hole of the first wall panel and welding the connection between the steel bar 004 and the first wall panel may include the following steps:

[0232] S1051. Provide a plurality of steel bars 004. The plurality of reinforcing trusses 003 in the first wall panel form a plurality of steel bar insertion holes. The plurality of steel bars 004 are inserted into the plurality of steel bar insertion holes in a one-to-one correspondence.

[0233] S1053, the connection between the welded steel bar 004 and the first wall panel.

[0234] In an alternative embodiment, please refer to Fig.25 , which is a schematic flow chart of the panel laying process in the prefabricated wall panel production process.

[0235] Laying the panel 005 on the second surface of the first wall panel to form the second wall panel may include the following steps:

[0236] S1251. Pre-position the panel 005 to be laid before laying.

[0237] S1253, grab the pre-positioned panel 005 to be laid, and lay it to the target stiffening truss 003 position.

[0238] It can be understood that the panel 005 here may include a panel 005 made of cement board and other materials.

[0239] In order to increase the stability of panel 005 after laying, a gluing station can also be set before the panel 005 laying station. For further information, please refer to Fig.26 , shown is a schematic diagram of the process of prefabricated wall panel production process.

[0240] Specifically, between step S108 and step S125, the following steps may also be included:

[0241] S122. Apply glue to the second surface of the stiffening truss 003 in the first wall panel.

[0242] This step can be performed at the gluing station of the prefabricated wall panel production line 100, which is located between the flipping station and the panel laying station, and the gluing mechanism 052 is used to glue the second surface of all the stiffening trusses 003.

[0243] The gluing mechanism 052 needs to be assisted by the conveying mechanism 077. The glue gun is provided with multiple gluing heads, which are arranged in sequence along the second direction 009. The multiple gluing heads correspond to the multiple stiffening trusses 003 one by one. The glue gun is installed on the adjustment mechanism, and the adjustment mechanism drives the glue gun to move up and down so that the gluing head is close to the top of the stiffening truss 003 or away from the stiffening truss 003; the adjustment mechanism also drives the glue gun to swing horizontally left and right. When the adjustment mechanism drives the glue gun to swing left and right, the conveying mechanism 077 drives the first wall panel forward, thereby realizing that the multiple gluing heads simultaneously apply snake-shaped or Z-shaped glue on the multiple stiffening trusses 003, which is convenient for the subsequent panel 005 to be bonded and laid on the stiffening truss 003.

[0244] Optionally, the gluing station may include a first gluing station 050 and a second gluing station 082. The first gluing station 050 may be located at the next station of the flipping station, and is used to glue the second surface of the first wallboard's reinforced truss 003 welded firmly, so as to facilitate the laying of the panel 005 in the next process. The second gluing station 082 is located at the previous position before the panel 005 is subsequently laid on the first surface, and the specific position is determined according to actual needs.

[0245] After the second surface of the first wall panel is paved with the panel 005 to form the second wall panel, in order to improve the stability of the panel 005 in the second wall panel. Fig. 27 , shown is a schematic diagram of the process of prefabricated wall panel production process.

[0246] After step S125, the following steps may also be included:

[0247] S126. Fix the panel 005 and the stiffening truss 003 of the second wall panel by nailing.

[0248] This step can be performed at the nailing station of the prefabricated wall panel production line 100, which is located after the panel laying station, and the nailing mechanism 072 is used to drill and nail the second surfaces of all the panels 005 and the stiffening trusses 003.

[0249] S127, patching the missing nail positions in the second wall panel.

[0250] Optionally, a nail patching station may be provided after the nailing station, and the conveying mechanism 077 conveys the second wall panel to the nail patching station, and the nail patching may be performed manually.

[0251] S128, flip the second wall panel 180 degrees.

[0252] After the second wall panel has completed the laying and nailing of the panel 005, it is necessary to flip the second wall panel to 180 degrees again to facilitate the operation on the first surface of the second wall panel. This step can be performed at the second flipping station 080 of the prefabricated wall panel production line 100. The second flipping station 080 is located after the nailing station, and the flipping mechanism 041 is also used to flip the second wall panel.

[0253] S129. Apply glue to the first surface of the stiffening truss 003 in the second wall panel.

[0254] When the second wall panel is turned over, the second surface after laying panel 005 will be turned downward, and the first surface without laying panel 005 will be turned upward. The above-mentioned equipment and process method are used to apply glue to the first surface of the stiffening truss 003 in the second wall panel. The specific gluing process can be referred to the above description and will not be repeated here.

[0255] S130, laying panel 005 on the first surface of the second wall panel to form a third wall panel.

[0257] S131. Fix the panel 005 and the reinforcing truss 003 of the third wall panel by nailing.

[0258] When the second wall panel is completed with the panel 005 laid to form a third wall panel, holes can be drilled and nailed on the first surface of the third wall panel to fix the panel 005 on the first surface with the stiffening truss 003. The specific process of nailing can refer to the above description and will not be repeated here.

[0259] S132, patching the missing nail positions in the third wall panel.

[0260] After the overall nailing is completed, in order to avoid the phenomenon of missing nails or incomplete nailing, a nail patching station can be set up to perform manual nail patching on the first surface.

[0261] Finally, a quality inspection station 089 may be provided, at which a visual camera may be used to inspect the external dimensions of the third wall panel.

[0262] In summary, the prefabricated wall panel production process adopts a fully automated production method in the form of an assembly line, and multiple wall panel components such as square columns 002, stiffening trusses 003, steel bars 004, and panels 005 are assembled, welded, and fixed to finally form prefabricated wall panels 001.
