Description

Technical Field

[0001] The present application relates to the field of metal plate corner welding technology, and in particular to an automated plate corner welding device and control system. Background Art

[0002] Corner welding is a basic and key connection technology for the metal sheet processing industry and the metal manufacturing industry. It connects two metal sheets at perpendicular angles to form a stable and reliable overall structure. The application of corner welding has penetrated into all walks of life and plays an important role.

[0003] Fillet welding of metal sheets is to form a weld at the edge intersection of two metal parts to achieve connection, and the welding operation is mostly performed manually by welders. Nowadays, there are automated fillet welding equipment, which greatly improves the output efficiency of metal sheet welded parts. Specifically, technicians pre-set the welding parameters of the welding machine, including welding current, voltage, speed, etc. During the fillet welding process, the automated welder fixes the welding plate on the welding table and feeds the welding gun to complete the welding.

[0004] However, most of the existing automated fillet welding equipment can only weld two metal sheets, and can only weld two sheets at right angles. In view of the above-mentioned related technologies, the inventor believes that the existing automated fillet welding equipment can be improved from the structural composition level of the automated welding equipment, the welding quantity and welding angle of the metal sheets can be increased, and the flexibility of the automated welding equipment can be improved.

[0005] Application Contents In order to enhance the flexibility of automated welding equipment, the present invention provides an automated plate fillet welding device and a control system.

[0006] On the one hand, the present invention provides an automated plate fillet welding device that adopts the following technical solution: An automated plate fillet welding device and control system, comprising a housing, a welding platform is arranged on the central part of the housing, a plurality of welding guns are arranged on the housing corresponding to the welding platform, and further comprising: Two chassis plates are arranged in parallel, the edges of the two chassis plates facing each other are hinged to the surface of the welding platform, and the edges facing each other are free sides. The welding platform is provided with a driving assembly below the two chassis plates to drive the chassis plates to rotate; The first fixing components are horizontally arranged, and two of them are symmetrically arranged above two opposite sides of the welding platform, and the two first fixing components are inclinedly arranged near one end of the bottom frame plate; the angles of the inclined parts of the two first fixing components are changed; A second fixing assembly is vertically arranged above the welding table; The side support assembly is arranged on the opposite sides of the welding platform corresponding to the two bottom frame plates, and is used to support the bottom frame plates.

[0007] By adopting the above technical solution, the casing is the shell structure of the fillet welding device, a chamber for welding work is opened inside the casing, and the welding table is arranged in the chamber; the welding table is the main bearing structure in the metal plate welding process, the first fixing assembly, the second fixing assembly, and the side support assembly on the welding table are the main fixing parts of the metal plate before welding, the welding gun is aligned with the weld between the metal plates, and the welding gun is fed toward the weld during welding to complete the welding; Specifically, the first fixing component is horizontally arranged to fix the metal sheet placed obliquely on the chassis plate. The initial state of the chassis plate should fit the surface of the welding table. Before the welding work starts, the two chassis plates should be rotated around the two back edges to an inclined state. The angle between the two chassis plates is the preset welding angle of the two metal sheets. The welding personnel should place the plate surface of the metal sheet on the inclined plate surface of the two chassis plates in advance. The top side edges of the two metal sheets in the inclined state fit together to form a weld. The first fixing component operates, and the angle change component at its end changes the angle to fit the metal sheet on the chassis plate surface. Force is applied and fixed to make the metal sheet press against the chassis plate surface to complete the fixation. In the above process, the metal plate is fixed by the first fixing assembly, and the bottom frame plate is fixed in an inclined state by the side support assembly. The side support assembly is connected to the bottom frame plate in a horizontal hinged manner to support the bottom frame plate to rotate in a vertical plane. The side support assembly also needs to have a sliding effect. During the rotation of the bottom frame plate with a fixed plate size, the side support assembly slides horizontally along the welding table synchronously, and is fixed at the preset position to fix the bottom frame plate. Thus, under the support of the side support assembly, by changing the inclination angle of the bottom frame plate, the two bottom frame plates are synchronously rotated until the angle between the two bottom frame plate surfaces is the preset angle. After the technician places the metal plates on the two bottom frame plates, the angle between the two metal plates is the angle between the bottom frame plate surfaces. In addition to the traditional two-plate welding, the above scheme can also realize three-plate welding. During the three-plate welding process, two of the plates are respectively tilted on the bottom frame plate, and the two metal plates are at a preset angle. The third metal plate is vertically arranged, and the bottom edge abuts against the welds of the two metal plates. The third metal plate is fixed by a second fixing component arranged above the welding table to maintain a stable vertical state, and the bottom edge of the third metal plate abuts against the two metal plates. It should be noted that during the welding of the three plates, the third plate set vertically is used as the reference plate. Regardless of the angles between the three plates, the third metal plate in the above scheme remains vertical, and the angles of the two bottom frame plates are changed to change the angles of the remaining two metal plates; In the above solution, the angles between the two base plates and the horizontal plane may be different.

[0008] Optionally, the first fixing component includes: A first sliding block is vertically slidably connected to the inner wall of the housing, and a first fixing rod arranged horizontally is formed on the first sliding block; The first fixing plate is hinged to one end of the first fixing rod which is away from the first sliding block, and its hinge axis is parallel to the hinge axis on one side of the base plate.

[0009] By adopting the above technical solution, the first fixing component has the functions of sliding, telescoping, and angle change, and is used to fix the metal plate placed at a preset angle on the inclined chassis plate. The fixed end of the first fixing component needs to change its own angle according to the inclination angle of the chassis plate, so that it is parallel to the plate surface of the chassis plate; the first fixing component also needs to change its own height by vertical sliding to correspond to the height of the chassis plate at different inclination angles; Specifically, the horizontally arranged first fixing rod is the main structure of the first fixing assembly, the length direction of the first fixing rod is perpendicular to the length direction of the base plate, that is, perpendicular to the placement direction of the metal plate on the base plate, one end of the first fixing rod close to the inner wall of the casing is fixedly connected to the slider, the slider slides vertically along the inner wall of the casing, and the first fixing plate hinged at one end of the first fixing rod close to the base plate can rotate freely in the vertical plane; Thus, in the initial state, gravity makes the plate surface of the first fixed plate horizontal, and the rod body length of the first fixed rod is a preset length, so that the plate surface of the first fixed plate extends above the inclined bottom frame plate, and then the first slider slides vertically downward along the inner wall of the casing, so that the first fixed plate moves downward and abuts against the bottom frame plate, and the first slider keeps moving downward, and the plate surface of the bottom frame plate hinged to the first fixed rod gradually fits the metal plate fixed on the inclined bottom frame plate; In addition, in the above scheme, there may be another fixing method of the first fixing plate, wherein the first fixing rod is provided with a clamping structure corresponding to the first fixing plate, so that the first fixing plate cannot be changed into a horizontal state in a free state due to the restriction of the clamping structure, but into an inclined state, thereby, after the first fixing plate is fed, its plate surface directly contacts the metal plate on the bottom frame plate; Regardless of the above-mentioned abutting manner, after the metal plate abuts against the first fixing plate, the two first fixing rods apply horizontal forces towards each other to make the metal plate continuously abut against the bottom frame plate, thereby completing the fixation.

[0010] Optionally, the second fixing component includes: Two second sliders are arranged at the same height above the bottom frame plate, and the two second sliders are horizontally slidably connected to the inner wall of the housing; The second fixing rod has a length direction parallel to the length direction of the base plate. A plurality of second fixing plates are distributed on the rod body of the second fixing rod. The second fixing plates have vertical plate surfaces. The second fixing plates on the two second fixing rods are arranged on opposite sides of the second fixing rod.

[0011] By adopting the above technical solution, the second fixing assembly is applicable to the case of three-plate welding in the above solution. In addition to the metal plates on the two bottom frame plates, the technicians place the bottom edge of a vertically arranged metal plate on the weld of the metal plates on the two bottom frame plates, and the cross section forms a triangular structure. The second fixing assembly is used to fix the vertically arranged metal plate; Specifically, the height of the two second sliding blocks is higher than the height of the base plate. The second sliding blocks slide toward and away from each other, driving the second fixed rod to maintain a horizontal position and change the position of the rod body. The two second fixed rods are provided with multiple second fixed plates facing each other, and the second fixed plates are distributed along the length direction of the second fixed rods, that is, along the length direction of the base plate. When the two second sliding blocks slide toward each other, the two second fixed plates press against the third metal plate placed by the technician.

[0012] Optionally, the side support assembly includes: A side plate, the length direction of which is parallel to the length direction of the base plate, and the side edge of the side plate close to the base plate is hinged to the base plate; The side sliding blocks are slidably connected to the welding platform, are arranged corresponding to the two ends of each side plate, and are hingedly arranged with the two ends of the edge of one side of the bottom frame plate away from the bottom frame plate.

[0013] By adopting the above technical scheme, the side support components are arranged on the opposite sides of the two bottom frame plates to support the two bottom frame plates, and the opposite sides of the two bottom frame plates are respectively hinged to the side plates, so that the plate surfaces of the two bottom frame plates can rotate freely around the hinged sides, and the inclination angle of the plate surfaces can be changed. The side plates on both sides rotate synchronously while the bottom frame plates rotate, and change from a horizontal angle to an inclined state. At the same time, the side sliders at the two ends of the opposite sides of the side plates slide toward each other when the side plates rotate, and the rotation of the side plates and the bottom frame plates when the plate surface sizes are fixed is structurally supported; however, in actual application, a fixing component for fixing the side sliders needs to be set on the welding table; In summary, the purpose of setting the side plates in the above scheme is to support the height change requirement when the base plate rotates. Before the welding process starts, for metal plates whose plate size is wider than the base plate size, the inclination of the base plate alone cannot effectively support the welding of the metal plates, so the height of the base plate needs to be raised.

[0014] Optionally, a gap is provided between the facing side edges of the two chassis plates.

[0015] By adopting the above technical solution, a gap is set between the facing side edges of the two bottom frame plates in a horizontal state. After rotation, the gap between the top side edges of the two bottom frame plates increases, providing space required for joining the weld and welding when technicians form a weld at the top of the two metal plates, thereby improving the operability of welding. On the contrary, if the two chassis plates are closely fitted together, the degree of wear on the facing edges of the two chassis plates will increase, thus reducing the service life of the chassis plates.

[0016] Optionally, a slag groove is provided on the welding table surface below the gap between the two base plates.

[0017] By adopting the above technical solution, metal slag adheres to the surface of the metal plate due to grinding, extrusion and other processes before welding. The gap between the two frame plates below the weld of the metal plate and the slag trough are in a vertical plane. When the top ends of the two metal plates abut to form a weld, the slag trough provides a channel for the welding table where the weld falls, thereby improving the welding quality.

[0018] On the other hand, the control system of an automated plate fillet welding device provided by the present invention adopts the following technical solution: A control system for an automated plate fillet welding device, characterized in that it comprises a central processing module, a front-end control module, a data acquisition module, and a display module; The data acquisition module collects the operation information of the first fixing assembly, the second fixing assembly, and the side support assembly, including the welding gun voltage, current, and the air pressure and air flow rate of the air gun; the data acquisition module is connected to the central processing module to send the operation information of the fillet welding device to the central processing module; The central processing module stores instruction files and data files. The central processing module receives data information from the data acquisition module, imports relevant data files to calculate data results, and runs relevant instruction files to generate corresponding instruction signals. The central processing module sends the data results to the display module and sends the instruction signals to the front-end control module. The front-end control module receives the command signal of the central processing module, and specifically executes and controls the operation of the first fixing component, the second fixing component, and the side support component; The display module is connected to the central processing module to display the data results and command signals of the central processing module.

[0019] Optionally, it also includes a data writing module and a wireless module; The data writing module is connected to the central processing module to provide the corner welding device operation data and operation status adjustment channel; the technician inputs instructions through the data writing module to overwrite the original instructions of the central processing module, and the front-end control module preferentially executes the writing instructions of the data writing module; The wireless module is connected to the data writing module and the central processing module, and is used for remote transmission of data and instructions of the data writing module and the central processing module.

[0020] By adopting the above technical solution, the central processing module, the front-end control module, the data acquisition module, the display module, the wireless module and the data writing module together constitute the control system of the automatic fillet welding device; Among them, the central processing module has the functions of data calculation and command sending, and is the central control module in this control system. The data acquisition module is mainly used for the operation status and information collection of each active component in the automated fillet welding equipment, and sends the collected data information to the central processing module. The central processing module processes, analyzes, and calculates, and forms a command signal according to the operation status of each component in the device, and sends it to the front-end control module. The front-end control module specifically executes the generated instructions of the central processing module to control the operation of active components such as welding guns, welding circuits, and air guns inside the device; Thus, the data acquisition module, the central processing module, and the front-end control module together form a control feedback system, realizing the feedback loop of data acquisition, command generation, and control operation; In addition to being generated by the central processing module, the execution instructions of the front-end control module can also be written by the data writing module. In the above scheme, the instructions of the data writing module have a higher priority than the instructions of the central processing module, and the front-end control module preferentially executes the instructions of the data writing module; during the above instruction writing process, the wireless module supports remote writing of the data writing module; During the welding process of the above-mentioned metal plates, the display module displays the data calculation results and instruction generation results of the central processing module and the control operation status of the front-end control module, so that the technicians can instantly understand the operation status of the automated corner welding equipment.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The design of the chassis plate and drive assembly enables precise rotation of the plate during welding, significantly improving the accuracy and efficiency of fillet welding operations and meeting the requirements for welding metal plates at various angles, not limited to right-angle welding; 2. The tilt setting of the first fixing component and its angle change enable plates of different specifications to be fixed more accurately, enhancing the adaptability and flexibility of the device; the setting of the second fixing component can stabilize the plate in the vertical direction, ensuring that the position of the plate is more stable during welding, further improving the welding quality; 3. The data acquisition module collects the welding gun voltage, current, air gun pressure and air flow rate information in real time. The central processing module automatically optimizes the welding parameters based on the collected information, significantly improving the welding accuracy and efficiency. The data writing module can remotely update the instructions in the central processing module, so that the front-end control module executes the new instructions first, enhancing the flexibility and response speed of the system.

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] In one aspect, the present application discloses an automated plate fillet welding device. Figure 1 An automated plate fillet welding device comprises a casing 1, an electric control box is arranged on the side wall of the casing 1, and a welding chamber 11 is opened in the casing 1; a welding table 2 is formed on the inner wall of the casing 1 corresponding to the welding chamber 11, and the welding table 2 is arranged horizontally. The main component of the fillet welding device in this embodiment is arranged on the welding table 2; a welding gun 12 is arranged on both opposite sides of the inner top wall of the welding chamber 11 corresponding to the welding table 2, and the ends of the welding gun 12 are arranged facing each other and extend to the part above the welding table 2 close to the welding table 2 surface, which is the main welding structural part.

[0030] Reference Figure 2 and Figure 3The welding table 2 is in the shape of a rectangular block, and the four corners of the table top are horizontally provided with side slide grooves 23, and the side sliders 231 are slidably connected in the side slide grooves 23, and the side sliders 231 are slidably connected in the side slide grooves 23. In this embodiment, no active driving structure is provided in the side slide grooves 23, and the side sliders 231 are used as passive sliding parts; in order to fix the side sliders 231, the inner bottom wall of the side slide grooves 23 is composed of electromagnets. When the side sliders 231 slide to the corresponding position, the electromagnets are energized and adsorbed to fix the side sliders 231 at the corresponding position; therefore, the material of the side sliders 231 in this embodiment needs to be composed of magnetic materials, preferably stainless steel.

[0031] Reference Figure 2 and Figure 3 Two side panels 232 are arranged in parallel on the welding platform 2. The two side panels 232 are arranged at the two opposite side edges of the welding platform 2. Both ends of the opposite side edges of the two side panels 232 extend to between the two side sliders 231 of the same side edge of the welding platform 2, so that both ends of the opposite side edges of the two side panels 232 are hinged to the opposite sides of the two side sliders 231, and the hinge axis is horizontal, so that the side panels 232 can rotate around the hinged side. A bottom frame plate 3 is hinged to the opposite sides of the two side panels 232. The opposite sides of the two bottom frame plates 3 are free sides, so that the two bottom frame plates 3 can rotate freely around the opposite side edges of the two side panels 232; the bottom frame plate 3 is the main frame supporting the corner welding of the metal plate; in this embodiment, the plate length of the bottom frame plate 3 is equal to the plate length of the side panel 232, and the plate width of the bottom frame plate 3 is greater than the plate width of the side panel 232, so that most of the weight of the metal plate is borne by the bottom frame plate 3 when it is placed.

[0032] Reference Figure 2 and Figure 3 The welding table 2 is provided with a driving groove 31 on the bottom side of the side plate 232 corresponding to the welding table 2. The driving grooves 31 are distributed along the length direction of the bottom frame plate 3. Two driving members are arranged in each driving groove 31 to serve as driving members for the rotation of the bottom frame plate 3 and the side plate 232. The two driving members are distributed along the length direction of the driving groove 31. In this embodiment, the driving member is an electric cylinder 32. The cylinder body of the electric cylinder 32 is hinged to the bottom wall of the driving groove 31. The piston rod of the electric cylinder 32 is hinged to the bottom side of the bottom frame plate 3. Therefore, the piston rods of all the electric cylinders 32 corresponding to one bottom frame plate 3 are extended synchronously to push the bottom frame plate 3 to rotate around the hinged side. When the piston rod of the electric cylinder 32 is extended to a large length, the bottom frame plate 3 pulls the side plate 232 to rotate, thereby driving the side sliders 231 on the opposite sides of the side plates 232 to slide. Fixing the side slider 231 and adjusting the extension length of the piston rod of the electric cylinder 32 can control the angle of the bottom frame plate 3, that is, the welding angle of the two metal plates.

[0033] Reference Figure 2 and Figure 3A slag trough 24 is vertically provided on the welding table 2. The slag trough 24 is provided below the facing side edges of the two bottom frame plates 3, and is used for the metal slag to fall during welding. The metal slag falls to the bottom of the casing 1 through the slag trough 24, and the metal slag is prevented from accumulating on the welding table 2. Furthermore, in order to ensure the smooth falling of the metal slag, a gap is provided between the facing side edges of the two bottom frame plates 3 in a horizontal state, and as the bottom frame plates 3 rotate upward, the gap between the bottom frame plates 3 increases, and sufficient welding space is reserved during welding.

[0034] Reference Figure 2 and Figure 4 , symmetrically provided with screw grooves on the inner walls of the two opposite sides of the welding bin 11, the two screw grooves have the same structure, and one of them is taken as an example; the screw groove is vertically opened, and a screw is rotatably connected in the screw groove, and a motor is arranged above the screw groove corresponding to the inner wall of the welding bin 11 to drive the screw to rotate, and a first slider 211 is penetrated and threadedly connected on the screw, and as the screw rotates, the first slider 211 slides vertically along the screw groove, and a horizontally arranged first fixing rod 212 is horizontally fixedly connected to the first slider 211, and a horizontally arranged driving cylinder is fixedly connected to the end of the first fixing rod 212 away from the first slider 211, and the cylinder body of the first driving cylinder 215 is horizontally arranged, and the piston rod of the first driving cylinder 215 faces the two bottom frame plates 3, and the piston rod end of the first driving cylinder 215 is hinged with the first fixing plate 213, and the hinge axis of the two is horizontally arranged parallel to the length direction of the bottom frame plate 3, so that the first fixing plate 213 can rotate in the vertical plane around the hinge axis. A clamping block 214 is formed at the end of the piston rod of the driving cylinder, or in the present embodiment, the clamping block 214 is formed on the first fixed plate 213. When only gravity acts, the surface of the first fixed plate 213 is abutted against the clamping block 214 and the main part of the driving cylinder piston rod, thereby preventing the surface of the first fixed plate 213 from becoming horizontal due to an unrestricted structure.

[0035] Therefore, when the technician places the metal sheet on the two base plates 3, the first slider 211 slides vertically to a height aligned with the metal sheet on the base plate 3, and the first driving cylinder 215 extends the piston rod, and the first fixed plate 213 abuts the metal sheet. The first driving cylinder 215 keeps the piston rod extended, so that the surface of the first fixed plate 213 is pressed against the surface of the metal sheet to complete the fixation.

[0036] The first fixing plate 213 , the first driving cylinder 215 , the first sliding block 211 , and the first fixing rod 212 constitute a first fixing assembly 21 , which is used to fix the metal plate placed obliquely on the base plate 3 in this embodiment.

[0037] Reference Figure 2, a second fixing assembly 22 is provided on a warehouse wall of the welding warehouse 11 between the two warehouse walls where the first fixing assembly 21 is provided, the second fixing assembly 22 includes a second slide groove, the second slide groove is horizontally opened above the two bottom frame plates 3, two second sliding blocks 3 are slidably connected in the second slide groove, a second driving cylinder is provided in the second slide groove corresponding to each second sliding block 3, the second driving cylinders are arranged oppositely, and the piston rods are extended and retracted to make the two second sliding blocks 3 slide towards and back to each other; a second fixing rod 1 is horizontally provided on each second sliding block 3 corresponding to the part above the table top of the welding table 2, one end of the second fixing rod 1 is fixedly connected to the second sliding block 3, and a plurality of vertically arranged second fixing plates 2 are fixedly connected to the facing sides of the two second fixing rods 1, and the plurality of second fixing plates 2 are evenly spaced along the length direction of the second fixing rod 1. In this embodiment, the distribution range of the second fixing plates 2 is limited to above the two bottom frame plates 3, and the second fixing rods 1 correspond to the bottom frame plates 3 one by one.

[0038] Thus, the second fixing plates 2 can slide toward each other, and after the technicians vertically place the metal plates on the weld of the two metal plates, the two second fixing plates 2 are clamped toward each other to achieve fixation.

[0039] The implementation principle of an automated plate corner welding device and control system in the embodiment of the present application is as follows: after the technician places the metal plate on the two base plates 3, the first slider 211 slides vertically to align the height with the metal plate on the base plate 3, the first driving cylinder 215 extends the piston rod, the first fixed plate 213 abuts the metal plate, and the first driving cylinder 215 keeps the piston rod extended, so that the surface of the first fixed plate 213 is pressed against the surface of the metal plate to complete the fixation. The second fixed plate 2 can slide toward each other. When welding three plates, after the technician places the metal plate vertically on the weld of the two metal plates, the two second fixed plates 2 clamp toward each other to achieve fixation.

[0040] On the other hand, the embodiment of the present application discloses a control system for an automated plate fillet welding device, which is used to control the automated plate fillet welding device described above. Figure 5A control system for an automated plate fillet welding device includes a central processing module 5, a front-end control module 6, a data acquisition module 81, a display module 7, a data writing module 82, and a wireless module 8. The data acquisition module 81 collects the operation information of the first fixed component 21, the second fixed component 22, and the side support component, including the voltage and current of the welding gun 12 and the air pressure and air flow rate of the air gun, and sends the collected information to the central processing module 5. The central processing module 5 stores instruction files and data files internally, and is generally preferably an electronic control component integrated with a machine tool. The central processing module 5 receives the data information of the data acquisition module 81, brings in the relevant data files to calculate the data results, runs the relevant instruction files to generate corresponding instruction signals, and controls the front-end control module 6 to execute according to the instructions; the front-end control module 6 is mainly composed of the electronic control circuits of the active parts of this embodiment, such as the first driving cylinder 215, the second driving cylinder, and the welding gun 12, receives the main control signal of the central processing module 5, and controls the first driving cylinder 215, the second driving cylinder, and the welding gun 12 to operate according to the relevant instructions.

[0041] Reference Figure 5 The data writing module 82 is connected to the central processing module 5 to provide the corner welding device with operating data and operating status adjustment channels; the technician inputs instructions through the data writing module 82 to overwrite the original instructions of the central processing module 5, and the front-end control module 6 gives priority to executing the write instructions of the data writing module 82.

[0042] Reference Figure 5 The wireless module 8 connects the data writing module 82 and the central processing module 5 , and the data acquisition module 81 and the central processing module 5 , and is used for remote transmission and reception of data and instructions between the data acquisition module 81 , the data writing module 82 and the central processing module 5 .
