[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] In the embodiments of this application, such as Figures 1 to 9 As shown, the steel mesh production line includes a conveyor rail 1, a steel bar laying device 2, a welding platform 3, and a production controller; among which,

[0054] A working space exists between the conveyor rail 1 and the ground. A first mechanical gripper 11 is slidably mounted on the conveyor rail 1. The working space includes a first storage area, a second storage area, a first working area, and a second working area. The first storage area, the first working area, the second working area, and the second storage area are arranged sequentially along the length of the conveyor rail 1. (See [reference]) Figure 1 In this embodiment, the first storage area is used to store tooling (templates for steel mesh); the second storage area is used to store finished products (welded steel mesh).

[0055] The rebar laying device 2 and the welding platform 3 are respectively set in the first work area and the second work area;

[0056] The first mechanical gripper 11, the rebar laying device 2, and the welding platform 3 are all connected to the production controller signal.

[0057] During the production of steel mesh, workers can activate the first mechanical gripper 11, the steel bar laying device 2 and the welding platform 3 through the production controller. The first mechanical gripper 11 will grab the tooling in the first storage area and send it to the welding platform 3.

[0058] Subsequently, the rebar placement device 2 can place the rebar in the fixture on the welding platform 3, that is, place the prepared rebar in the fixture according to the requirements (the placement direction of the rebar and the distance between two adjacent rebars);

[0059] After the reinforcement laying device 2 completes the reinforcement laying, the welding end in the welding platform 3 will weld the intersection of the reinforcement to fix the reinforcement.

[0060] After the steel mesh is welded, the first mechanical gripper 11 can pick up the finished product and send it to the second storage area. The first mechanical gripper 11, the steel bar laying device 2, and the welding platform 3 can repeat the above actions to continuously complete the production of steel mesh. The entire production process only requires the staff to start and stop the steel mesh production line. The tooling position change and the handling of finished products do not need to be done manually, so as to reduce the labor intensity of the steel mesh production process and improve production efficiency.

[0061] In some embodiments, the above-described rebar placement device 2 includes a placement platform 21, a second mechanical gripper 22, and a placement controller 23. (See also...) Figure 2 ;in,

[0062] The second mechanical gripper 22 includes a mechanical arm 221 and at least two gripping parts 222. One end of the mechanical arm 221 is disposed on the storage platform 21, and all the gripping parts 222 are disposed on the other end of the mechanical arm 221 and are located in the same plane.

[0063] Both the robotic arm 221 and the gripping part 222 are connected to the deployment controller 23 via signals.

[0064] The operator can control the movement of the second mechanical gripper 22 through the deployment controller 23. All the clamping parts 222 on the second mechanical gripper 22 can clamp the steel bars on the placement platform 21, and the mechanical arm 221 drives the clamping parts 222 to move and place the clamped steel bars into the tooling as required.

[0065] Then, welding can be carried out at the welding end of welding platform 3 to complete the preparation of the steel mesh.

[0066] In this embodiment, the second mechanical gripper 22 can replace manual labor to grab and lay out the reinforcing bars, and can grab and lay out two or more reinforcing bars at a time, thereby shortening the preparation time when preparing the reinforcing bar mesh and further improving the production efficiency of the reinforcing bar mesh.

[0067] It should be noted that the production controller and deployment controller 23 mentioned above are both PLC controllers (programmable logic controllers) or PAC controllers (programmable automation controllers).

[0068] In some embodiments, the second mechanical gripper 22 described above further includes a mounting plate 223, see [link to documentation]. Figure 3 ;in,

[0069] Mounting plate 223 is set at the end of robotic arm 221 away from the loading platform 21 to increase the mounting area of ​​robotic arm 221 away from the loading platform 21, which facilitates the installation of two or more clamping parts 222.

[0070] All clamping parts 222 are mounted on the mounting plate 223.

[0071] In some embodiments, the end of the robotic arm 221 away from the loading platform 21 is provided with a slewing bearing 224 and a slewing drive, see [reference]. Figure 3 ;

[0072] Mounting plate 223 is mounted on slewing bearing 224, and the rotation axis of slewing bearing 224 is perpendicular to the plane where mounting plate 223 is located. The actuating end of slewing drive is connected to slewing bearing 224 for transmission, and slewing drive is connected to layout controller 23 for signal.

[0073] The layout controller 23 can control the rotation drive action, and drive the mounting plate 223 to move through the slewing bearing 224 to adjust the length direction of the steel bar gripped by the clamping part 222, thereby satisfying the arrangement of longitudinal and transverse steel bars.

[0074] It should be noted that the slewing bearing 224, also known as the slewing disc 313 bearing or slewing disc 313 support, is a large bearing that can simultaneously withstand axial force, radial force and overturning moment. It is known as the "joint of the machine" and has been widely used in industries such as marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery and industrial machinery. It will not be described in detail here.

[0075] In some embodiments, the clamping part 222 includes a slide rail and at least two claws, see [link to documentation]. Figure 3 ;

[0076] All the slide rails in the clamping parts 222 are arranged parallel and spaced apart on the mounting plate 223; in this embodiment, the slide rails are fixed to the mounting plate 223 by bolts, and the position of the slide rails can be adjusted according to the layout requirements. That is, the position of the slide rails can be adjusted according to the layout distance between two adjacent steel bars to meet the layout requirements of the steel bars.

[0077] All the grippers are slidably mounted on the slide rail along its length. Each gripper is equipped with a travel motor, the actuating end of which is connected to the slide rail for transmission, and the travel motor is connected to the controller for signal transmission.

[0078] When it is necessary to clamp the steel bar, the staff can adjust the spacing between two adjacent claws according to the length of the steel bar so that multiple claws on a clamping part 222 can clamp a steel bar at the same time to prevent the steel bar from falling off.

[0079] Preferably, the moving end of the walking motor is equipped with a friction wheel, which contacts the slide rail. When the controller controls the walking motor to rotate, the walking motor can drive the friction wheel to move, so that the chuck and the slide rail will have relative displacement, thereby realizing the change of the chuck position.

[0080] In some embodiments, the above-described rebar laying device 2 further includes a feeding mechanism 24 for conveying rebars to the placement platform 21, see [link to documentation]. Figure 2 The feeding mechanism 24 is signal-connected to the deployment controller 23;

[0081] The feeding mechanism 24 completes the conveying of steel bars, thereby further shortening the preparation time during the preparation of steel mesh and improving the production efficiency of steel mesh.

[0082] Specifically, the aforementioned feeding mechanism 24 includes a rebar storage rack and a straightening and cutting machine, see [link to relevant documentation]. Figure 2 ,in,

[0083] The straightening and cutting machine is a type of steel bar processing machinery, mainly used to straighten and cut steel bars, stainless steel wire, aluminum wire and other metal wires with a diameter of less than 14 mm. The cut is flat and the length is adjustable. It is widely used in the fields of construction mesh, welding wire processing and special-shaped mesh production. The output end of the straightening and cutting machine faces the placement platform 21, and the straightening and cutting machine is connected to the controller signal.

[0084] The steel bar coils are placed on the steel bar storage rack, with one end of the coil extending into the straightening and cutting machine. The straightening and cutting machine straightens the coiled steel bar, cuts it to the appropriate length as required, and conveys it to the storage platform 21. The mechanical gripper then picks up and lays the steel bar to improve the production efficiency of the steel mesh.

[0085] In some embodiments, the welding platform 3 includes a support platform 31 and a welding assembly 32, see [link to documentation]. Figure 4 ;in,

[0086] The support platform 31 is provided with a first placement area and a second placement area. The positions of the first placement area and the second placement area can be freely switched. In this embodiment, the first placement area and the second placement area can rotate around a vertical axis to realize the free switching of the positions of the first placement area and the second placement area.

[0087] The welding assembly 32 is disposed on the side of the support platform 31 and is used to weld the longitudinal and transverse reinforcing bars placed in the first or second placement area.

[0088] Both the first and second placement areas on the support platform 31 can be used to place tooling. When the position of the first placement area is switched to the welding position of the welding component 32, the welding end of the welding component 32 welds the longitudinal and transverse steel bars in the tooling placed in the first placement area. At the same time, the workers can use the first mechanical gripper 11 to place tooling in the second placement area and place longitudinal and transverse steel bars in the tooling in the second placement area, so as to realize the simultaneous placement of longitudinal and transverse steel bars and welding of steel mesh, thereby improving the production efficiency of steel mesh.

[0089] Preferably, the number of the first mechanical grippers 11 is two;

[0090] When alternating production of steel mesh of various sizes is required, the first mechanical gripper 11 can deliver a tooling of one size to the first placement area of ​​the welding platform 3 and place steel bars into the tooling through the steel bar placement device 2.

[0091] After the reinforcement bars are laid out, the positions of the first placement area and the second placement area can be switched so that the first placement area can be moved into the working area of ​​the welding assembly 32, and the reinforcement bars in operation can be welded by the welding assembly 32.

[0092] Meanwhile, the second mechanical gripper can deliver a tooling of another size to the first placement area of ​​the welding platform 3, and lay the reinforcing bars into the tooling through the reinforcing bar laying device 2; while the first mechanical gripper 11 is in standby mode. After the welding assembly 32 completes the welding of the reinforcing bars, the first mechanical gripper 11 can grab the finished product and send it to the second storage area. The two first mechanical grippers 11 can work synchronously without interfering with each other, thereby effectively improving the production efficiency of the reinforcing bar mesh.

[0093] In this embodiment, the welding assembly 32 includes a welding robot and a slide rail, see [link / reference]. Figure 4 and Figure 7 ,in,

[0094] The slide rail is arranged on one side of the support platform 31 along one of the directions, and the welding robot is slidably set on the slide rail along the length direction of the slide rail so that the welding robot can weld multiple intersections of longitudinal and transverse steel bars to better realize the production of steel mesh.

[0095] It is worth noting that the welding robot includes a robotic arm 221 and a welding torch. The welding torch is located at the working end of the robotic arm 221 and is the welding end of the aforementioned welding component 32. Before the welding robot starts working, the operator can write the position information of the intersection point of the longitudinal and transverse reinforcing bars into the control system of the robotic arm 221.

[0096] During welding, the control system of the robotic arm 221 can control the movement of the robotic arm 221, moving the welding torch to the intersection of the longitudinal and transverse reinforcing bars, and using the welding torch to weld the intersection of the longitudinal and transverse reinforcing bars to complete the welding of the reinforcing mesh.

[0097] Preferably, there are three welding components 32, and the slide rails in the three welding components 32 are arranged in a "U" shape. The first placement area or the second placement area in the support platform 31 is covered by the slide rails in the three welding components 32.

[0098] The simultaneous welding of the steel mesh by three welding components 32 can effectively improve the production efficiency of the steel mesh.

[0099] In some embodiments, the support platform 31 described above includes a support base 311, a rotary motor 312, and a turntable 313. (See also...) Figure 5 ;in,

[0100] The turntable 313 is rotatably mounted on the support base 311. The rotation axis of the turntable 313 is perpendicular to the horizontal plane. The first placement area and the second placement area are both located on the upper surface of the turntable 313 to facilitate the placement of longitudinal and transverse reinforcing bars and the welding of reinforcing mesh.

[0101] The rotary motor 312 is mounted on the support base 311, and the actuating end of the rotary motor 312 is connected to the turntable 313 for transmission. The rotation of the turntable 313 is controlled by the rotary motor 312 to improve the working efficiency of the steel mesh welding platform 3 and reduce the labor intensity in the steel mesh production process.

[0102] Specifically, the aforementioned turntable 313 is provided with a gear ring, the axis of which coincides with the rotation axis of the turntable 313;

[0103] The rotating motor 312 has a gear at its actuating end, and the actuating end of the rotating motor 312 is connected to the turntable 313 through the meshing of the gear and the gear ring.

[0104] In some embodiments, the upper end surface of the aforementioned support base 311 is provided with a support portion 42 and an annular guide rail, see [reference]. Figure 5 and Figure 6 The turntable 313 is rotatably mounted on the upper end face of the support part 42, and the rotary motor 312 is mounted on the side of the support part 42; the axis of the guide rail coincides with the rotation axis of the turntable 313.

[0105] The lower end face of the turntable 313 is provided with at least three support legs. All the support legs are arranged at equal intervals around the rotation axis of the turntable 313, and the end of the support leg away from the turntable 313 is provided with a pulley. The support leg is slidably mounted on the guide rail through the pulley to make the rotation of the turntable 313 smoother.

[0106] In some embodiments, both the first placement area and the second placement area are provided with clamping portions 222 for clamping the tooling; wherein,

[0107] Tooling, or molds, is used to limit and determine the range and position of longitudinal and transverse reinforcing bars;

[0108] The clamping part 222 is a mechanical gripper that can effectively fix the tooling;

[0109] The clamping part 222 is used to fix the tooling on the first placement area and the second placement area to ensure the placement quality of the longitudinal and transverse steel bars, thereby ensuring the uniformity and quality of the produced steel mesh.

[0110] In some embodiments, a transport device 4 is provided in the second storage area, see [reference]. Figure 1 ;

[0111] After the steel mesh is welded, the first mechanical gripper 11 can pick up the finished product and send it to the transport device 4 in the second storage area;

[0112] When steel mesh is needed, it can be transported to the designated location with the help of transport device 4, making the transportation of steel mesh more convenient.

[0113] In some embodiments, the transport device 4 includes a movable support frame 41, see [link to previous document]. Figure 8 and Figure 9 ;

[0114] The top surface of the movable support frame 41 is provided with a support part 42 and a limiting part 43. The support surface of the support part 42 is an inclined surface, and the limiting part 43 is located on the lower side of the support surface. The support surface and the limiting surface of the limiting part 43 together form a placement groove with a cross-section of "V".

[0115] The steel mesh placement and transportation device 4 can be placed in the finished product warehouse for storing steel mesh. When steel mesh is needed, the operator can use the steel mesh placement and transportation device 4 to transfer the steel mesh. That is, by pushing the mobile support frame 41, the steel mesh in the placement slot is transferred to the designated position, and then the operator can take the steel mesh out of the placement slot for use.

[0116] During the process of workers retrieving the steel mesh, because the steel mesh is placed at an angle in the placement groove, workers can grab the steel mesh without bending over, which makes it easy to retrieve the steel mesh, reduces the labor intensity of retrieving the steel mesh, and at the same time reduces the chance of workers getting injured while grabbing the steel mesh.

[0117] In some embodiments, the first storage area is provided with multiple sets of tooling brackets, which can hold multiple tooling of different sizes, thereby meeting the production of steel mesh of different sizes.

[0118] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
