Description

Technical Field

[0001] This invention relates to the field of metal plate welding technology, and in particular to an automated metal plate processing and welding device. Background Technology

[0002] The automated metal plate processing and welding equipment includes a clamping part for fixing the metal plates. Because the metal material generates a lot of heat during the welding process, causing the metal to expand and contract rapidly, if a rigid clamping method is used, the weld joint of the two metal plates may deform and introduce tolerances, making it difficult to meet the requirements of high-precision welding processes.

[0003] To address this issue, flexible clamping techniques are typically employed, such as buffer structures centered around springs or spring sheets, or flexible materials like polyurethane gaskets as padding layers. However, spring or spring-loaded buffer structures require customized adaptation based on the shape, thickness, and thermal conductivity of the metal plate, making the adjustment process complex and inconvenient to use. While buffer materials like polyurethane gaskets can overcome the drawbacks of spring or spring-loaded buffer structures, they are prone to plastic deformation under pressure, leading to a gradual loss of flexible clamping performance and consequently affecting welding quality, posing significant potential risks. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] To address the aforementioned problems, the present invention provides the following technical solution: an automated metal plate processing and welding device, comprising a welding assembly and a clamping assembly disposed on the welding assembly, characterized in that: the clamping assembly is provided with a movable buffer assembly, the buffer assembly comprising a positioning box and a limiting plate slidably disposed on the positioning box, the limiting plate being used to abut against the surface of the metal plate;

[0006] A buffer structure is provided between the positioning box and the limiting plate;

[0007] A screw is also provided between the limiting plate and the positioning box. By turning the screw, the limiting plate is driven to move relative to the positioning box to adjust the total cavity size of the buffer structure and cause the support to deform.

[0008] Preferably, the buffer structure has a total cavity inside, and the total cavity is provided with an elastically deformable support member. The buffer structure and the support member are an integral structure. The buffer structure is provided with a plurality of equally spaced support members, and the total cavity is divided into a first cavity, a second cavity and a third cavity between adjacent support members.

[0009] Preferably, the support member has micro-holes, so that the second cavity and the third cavity of the adjacent support member are connected.

[0010] Preferably, the support has two top ends and a bottom end, with the bent end of the support between the two top ends and the side end between the top and bottom ends, and micro-holes are provided on the side end.

[0011] Preferably, the outer surface of the buffer structure is provided with pleats.

[0012] Preferably, the outer surface of the buffer structure is provided with a conduit that communicates with the second cavity and the third cavity, and the end of the conduit is provided with a regulating valve.

[0013] Preferably, the outer ring of the end of the conduit has an opening, a axial protrusion at its center, and an outer ring protrusion on the outer surface of the conduit, with a sealing ring fitted on the outer surface of the outer ring protrusion.

[0014] Preferably, the conduit is matched with the regulating valve, and the fitting recess inside the regulating valve is sealed to the outer ring protrusion of the conduit by a sealing ring, and the axial recess of the regulating valve is matched with the axial protrusion of the conduit, so that the regulating valve can be rotatably mounted on the conduit.

[0015] Preferably, the regulating valve is provided with an adapter hole, and rotating the regulating valve causes the adapter hole to intersect with the opening of the conduit.

[0016] Preferably, the regulating valve is plugged by a plug, and the plug's adhesive material matches the opening of the regulating valve.

[0017] The beneficial effects of this invention are: intelligent switching and precise control of rigid / flexible states.

[0018] Through the linkage design of regulating valve 500 and conduit 402 (alignment / misalignment of adapter hole 500b and opening 402b), combined with the sealing effect of plug 501, the buffer structure 400 can achieve active or automatic switching between rigid mode (closed cavity) and flexible mode (medium flow).

[0019] Rigid mode: When the regulating valve is fully closed, the bent end 401-2 of the support 401 is in close contact with the inner wall of the buffer structure, each cavity independently maintains pressure, and the overall hardness is close to that of a solid gasket, ensuring the initial fixation of the metal plate.

[0020] Flexible mode: When the metal plate expands due to welding heat, the stress exceeds the threshold of the blockage 501. The medium is depressurized through the micropore 401a or the conduit 402 to achieve nonlinear buffering and avoid deformation caused by stress concentration.

[0021] The linear elasticity of traditional springs cannot adapt to the nonlinear displacement caused by thermal expansion and contraction, while this solution achieves dynamic adaptation through cavity pressure adjustment and medium flow.

[0022] Second; Simplified process and highly integrated structure

[0023] The buffer structure 400 and the support 401 are designed as a single unit (such as hollow sealing molding). The sealing can be completed by simple processes such as hot melting, without complicated assembly. The shape (such as M-shape) and cavity layout of the support 401 can be formed in one step by a mold, and different metal materials (such as stainless steel / aluminum alloy) can be flexibly adapted by adjusting the number of micropores 401a or the position of the conduit 402.

[0024] Compared with traditional solutions: traditional springs or spring sheets need to be installed and adjusted separately, and occupy a lot of space; this solution is directly integrated into the clamping assembly 200, without the need to modify the main structure of the welding device.

[0025] Third; Multi-level buffering mechanism: Through the flow limiting effect of micro-hole 401a, the medium pressure relief of conduit 402 and the critical value triggering of blockage 501, a segmented buffering effect is formed to accurately match the dynamic stress changes of the metal plate during the welding process.

[0026] Resistance to permanent deformation: The closed design of the first cavity 400a-1 provides pressure-holding support and prevents the buffer structure from failing after excessive compression; the pleats 400b enhance the structure's resilience and durability.

[0027] Traditional structural defects: springs are prone to fatigue after long-term compression and cannot achieve rigid locking; while this solution, through the synergistic effect of regulating valve 500 and support component 401, has the dual functions of rigid fixation and elastic buffering.

[0044] Example 1

[0045] Reference Figures 1 to 5This embodiment of the invention provides an automated metal plate processing and welding device, including a welding assembly 100 and a clamping assembly 200 disposed on the welding assembly 100. The clamping assembly 200 is provided with a movable buffer assembly 300. The clamping assembly 200 includes a support block 201, a screw sleeve 202 and a screw 203. The screw 203 is threadedly connected to the screw sleeve 202. One end of the screw 203 is rotatably connected to the outer surface of the positioning box 301. By driving the top knob of the screw 203, the limiting plate 302 in the positioning box 301 clamps the metal plate.

The welding gun 106 is controlled by a servo system and can achieve high-precision welding path tracking. This is the welding part of the welding device. A buffer structure 400 is provided between the positioning box 301 and the limiting plate 302. The buffer structure 400 has a total cavity 400a inside, and a support member 401 that can be elastically deformed is provided inside the total cavity 400a.

[0046] A screw 304 is also provided between the limiting plate 302 and the positioning box 301. By turning the screw 304, the limiting plate 302 is driven to move relative to the positioning box 301 to adjust the size of the total cavity 400a of the buffer structure 400 and to cause the support member 401 to deform.

[0047] The buffer structure 400 is provided with several equally spaced support members 401. The total cavity 400a is divided into a first cavity 400a-1, a second cavity 400a-2 and a third cavity 400a-3 by the adjacent support members 401. The support members 401 are provided with micro holes 401a, so that the second cavity 400a-2 and the third cavity 400a-3 of the adjacent support members 401 are connected. The support member 401 has two top ends 401-3 and a bottom end 401-4. The two top ends 401-3 are the bent end 401-2 of the support member 401, and the top end 401-3 and the bottom end 401-4 are the side end 401-1 of the support member 401. The micro holes 401a are provided on the side end 401-1.

[0048] Specifically, welding assembly 100

[0049] Includes a workbench 101 and a welding platform 102 fixed thereon;

[0050] The welding mobile support 103 is straddling above the welding platform 102 and is driven by the first drive mechanism 104 to move along the X-axis.

[0051] A second drive mechanism 105 is installed on the welding moving bracket 103 to drive the welding gun 106 to move along the Y-axis;

[0052] The welding gun 106 is controlled by a servo system to achieve high-precision welding path tracking. The following is a common configuration for this automated welding device: 1. Mechanical structure selection and matching.

[0053] (1) Workbench 101 and welding platform 102

[0054] Workbench: Select a heavy-duty welding workbench (such as MISUMI FA series or Shanglong automation platform) to ensure rigidity and stability. The size is determined according to the welding workpiece (e.g., 1200×800mm).

[0055] Welding platform: Made of high-temperature resistant steel plate (such as Q235A with chrome plating) and fixed on the workbench, with T-slots for easy fixture installation.

[0056] (2) Welding the mobile support 103

[0057] X-axis crossbeam: Select a high-precision linear module (such as HIWIN EGR series or THK SR series), and the span must cover the width of the welding platform (e.g., 1000mm stroke).

[0058] Y-axis slide: Installed on the X-axis module, a compact linear slide (such as the HIWIN KK module) should be selected, and the load should match the weight of the welding gun (approximately 5-10 kg).

[0059] (3) Drive mechanism (104 / 105)

[0060] X-axis drive (104): Servo motor (such as Panasonic MINAS A6 series 400W) + planetary reducer (speed ratio 10:1) + ball screw (diameter 20mm, lead 5mm).

[0061] Y-axis drive (105): Servo motor (200W) + synchronous belt drive (or small ball screw) to meet the requirements of fast response.

[0062] Guide rail: Linear guide rail matching the module (such as HIWIN HGR15), with repeatability accuracy of ±0.02mm.

[0063] (4) Welding gun (106)

[0064] Welding torch model: Select according to the process (such as TIG welding torch (WP-17) or MIG welding torch (Binzel MB36)), with water cooling system (if long-term welding is required).

[0065] Servo control: The height and angle of the welding torch are adjusted by a servo motor (such as the Yaskawa Σ-7 series), and constant pressure tracking is achieved by using a force sensor.

[0066] 2. Control System Integration

[0067] (1) Motion control

[0068] Controller: Uses a PLC (such as Mitsubishi FX5U) or a dedicated motion control card (such as Googol GTS series) to program and realize X / Y axis interpolation motion.

[0069] Servo drive: Match the motor model (such as Panasonic A6 driver), and set the electronic gear ratio and acceleration / deceleration curve.

[0070] (2) Welding parameter management

[0071] Welding power source: Select a digital welding machine (such as the Fronius TPS series) that supports communication with a PLC (Modbus TCP / IP or EtherCAT).

[0072] IO interface: Controls the welding machine's start / stop, gas valves, and wire feeder (during MIG welding) via PLC.

[0073] (3) Path tracking

[0074] High-precision sensing: Add a laser displacement sensor (such as the KEYENCE IL series) to compensate for workpiece deformation errors in real time.

[0075] Programming software: Use CAM software (such as Robotmaster) to generate welding paths and export G-code to the controller.

[0076] 3. System linkage process

[0077] initialization:

[0078] Return all axes to zero and reset the welding torch to a safe position.

[0079] Clamping the workpiece:

[0080] The metal plate is positioned using a clamp (such as a pneumatic gripper) or manually.

[0081] Welding execution:

[0082] The PLC sends commands, and the X / Y axes move along a preset path, while the welding torch servo system synchronously adjusts the height and angle.

[0083] Monitoring feedback:

[0084] Force sensors and laser sensors adjust parameters in real time to ensure weld quality.

[0085] Clamping assembly 200 (this clamp is for reference) Figures 1-3 )

[0086] It is mounted on the welding assembly 100 and includes a support block 201, a screw sleeve 202 and a screw rod 203;

[0087] The screw 203 is threadedly connected to the screw sleeve 202, and one end of it is rotatably connected to the outer surface of the positioning box 301.

[0088] By rotating the knob on the top of the screw 203, the limiting plate 302 inside the positioning box 301 is driven to clamp the metal plate.

[0089] II. Buffer System

[0090] Buffer component 300

[0091] It is movably mounted on the clamping assembly 200 and includes a positioning box 301 and a limiting plate 302.

[0092] A buffer structure 400 is provided between the two, which has a total cavity 400a inside and a built-in elastically deformable support member 401.

[0093] Buffer adjustment mechanism

[0094] The limiting plate 302 and the positioning box 301 are connected by screws 304. Tightening the screws 304 can drive the limiting plate 302 to move, adjust the size of the total cavity 400a and deform the support 401. This adapts to the stress of different metals during thermal expansion and contraction (e.g., the coefficients of thermal expansion of stainless steel and aluminum alloy are different). At the same time, the support 401 is appropriately compressed so that it and the buffer structure 400 act as pure gaskets to ensure the fixation of the metal plate in the positioning metal plate. For example, when the bent end 401-2 of the support 401 contacts the inside of the buffer structure 400, a single support 401 has three support ends in total, including the side end 401-1 and the bent end 401-2, so that the hardness of the entire buffer structure 400 is equivalent to that of a pure gasket. On this basis, the buffer structure 400 can be further compressed to a suitable degree according to the material of the metal plate. Specifically, the degree of compression of the buffer structure 400 can be controlled by refining the threads of the screws 304 and the positioning box 301 and adding a scale to the screws 304.

[0095] The support members 401 are arranged at equal intervals. During the design phase, the shape and quantity of the support members 401 can be determined according to the actual situation. Figure 5The middle support 401 is M-shaped, but in order to keep the metal block fixed in its position (that is, its performance is closer to that of a pure gasket, and the shape of the support 401 can be further changed), the total cavity 400a is divided into the first, second, and third cavities (400a-1 / 2 / 3). The first cavity 400a-1 is closed, which plays a role in maintaining pressure and also prevents the buffer structure 400 from plastic deformation due to compression. When the bent end 401-2 of the buffer structure 400 contacts the buffer structure 400, it can further close the second cavity 400a-2 and the third cavity 400a-3 to ensure the pressure-maintaining effect.

[0096] Structural features of support member 401:

[0097] It contains two top ends 401-3 and bottom ends 401-4, which are connected by a side end 401-1;

[0098] A bend 401-2 is formed between the top 401-3;

[0099] Microholes 401a are opened on the side end 401-1 to connect adjacent cavities (such as the second and third cavities). The microholes 401a on the side end 401-1 can minimize thermal expansion and displacement during the welding of the metal plate, thus buffering the metal plate. After the metal plate is welded, the bent end 401-2 of the buffer structure 400 completely contacts the inner wall of the buffer structure 400 to offset the further deformation of the metal plate. This ensures the fixation of the metal plate before welding, the buffering during welding, and the fixation of the metal plate in the initial stage after welding.

[0108] Displacement: ±5mm for aluminum alloy, ±3mm for steel plate (calculated based on the coefficient of thermal expansion);

[0109]

[0110] Detailed Explanation of Key Experimental Parameters

[0111] Support component 401 + buffer structure 400

[0112] Micropore 401a pressure relief rate:

[0113] Aluminum alloy: 0.1L / min (pore size 1.0mm, low viscosity medium).

[0114] Steel plate: 0.05L / min (0.5mm aperture, high viscosity oil).

[0115] Regulating valve opening 500:

[0116] Rigid mode: The adapter hole 500b and the opening hole 402b are misaligned by 90°.

[0117] Flexible mode: Opening angle 30° (aluminum alloy) / 15° (steel plate).

[0118] Fatigue failure mode:

[0119] The bent end 401-2 of the support 401 is slightly worn (wear depth <0.1mm after 50,000 cycles).

[0120] The pleats of the 400 cushioning structure are tear-free.

[0121] Traditional springs

[0122] Failure Mode:

[0123] Microcracks appeared after 10,000 cycles (the fatigue limit of 60Si2MnA steel was insufficient).

[0124] At high temperatures, the elastic modulus decreases, causing the clamping force to fluctuate by ±20%.

[0125] polyurethane gaskets

[0126] Failure Mode:

[0127] After 5,000 cycles, the thickness decreases by 10% to 15% (compression set).

[0128] The surface cracks under high temperature, and the cushioning performance is completely lost.

[0129] Comparison of fatigue performance curves

[0130] Support component 400: Fatigue life decreases linearly and slowly (stiffness remains at 95% after 50,000 cycles).

[0131] Springs: They decay rapidly in the first 5,000 cycles, and then enter a phase of accelerated fatigue.

[0132] Polyurethane gaskets: Initially, they degrade very quickly, and their performance drops drastically after 3,000 cycles.

[0133] Conclusion: The support component 401 and the buffer structure 400, through multi-cavity pressure distribution and integrated material design, are significantly superior to traditional solutions.

[0134] Lifespan increased by more than 3 times, deformation recovery rate close to 100% (fatigue resistance).

[0135] It can withstand high temperatures of 600℃ for a short period of time without any sudden change in performance (thermal stability).

[0136] It is worth mentioning that the buffer structure 400 and the support 401 are an integrated structure. The buffer structure 400 can be adapted to the existing clamping component 200 (such as a mechanical gripper with a clamping component 200 at the end of the mechanical gripper, which can be made into a circle or other shapes. The support 401 is constructed by hollowing out the first cavity 400a-1, the second cavity 400a-2, and the third cavity 400a-3, and then sealed. The process is simple, and the sealing method can be heat capacity, etc.). Its production cost and manufacturing difficulty are greatly reduced, and there is almost no modification to the entire welding device, which is in line with the logic of actual production and manufacturing.

[0137] 2. The traditional buffer structure of springs and clips is difficult to combine with traditional clamps (clamping components 200), and it is also difficult to match them one by one. The application range is narrow and it occupies a large proportion of the welding device, which does not conform to the logical relationship of actual production and manufacturing.

[0138] III. The internal support component 401 of the buffer structure 400 not only stores... Figure 4 The arrangement shown can also be a structure of a single multi-layer support member 401, or a side end 401-1 and a bent end 401-2 of a support member 401 with a thicker thickness. It can be modified flexibly and the process is simple. The main changes are to the shape and size of the first cavity 400a-1, the second cavity 400a-2, and the third cavity 400a-3, which once again demonstrates the simple and controllable characteristics of its process.

[0139] IV. The outer surface of the buffer structure 400 is provided with pleats 400b, which mainly enhances the recovery ability and resistance to deformation of the buffer structure 400.

[0140] Example 2

[0141] Reference Figures 3 to 7This is the second embodiment of the present invention. The difference between this embodiment and embodiment 1 is that the outer surface of the buffer structure 400 is provided with a conduit 402 that communicates with the second cavity 400a-2 and the third cavity 400a-3. A regulating valve 500 is provided at the end of the conduit 402. The outer ring of the end of the conduit 402 has an opening 402b, with a central axial protrusion 402c. The outer surface of the conduit 402 has an outer ring protrusion 402a, and a sealing ring 402a-1 is fitted onto the outer surface of the outer ring protrusion 402a. The conduit 402 cooperates with the regulating valve 500. The regulating valve 500 contains... The fitting recess 500a is sealed to the outer ring protrusion 402a of the conduit 402 by the sealing ring 402a-1, and the shaft recess 500c of the regulating valve 500 is engaged with the shaft protrusion 402c of the conduit 402 so that the regulating valve 500 can be rotatably mounted on the conduit 402. The regulating valve 500 is provided with a fitting hole 500b. Rotating the regulating valve 500 causes the fitting hole 500b to intersect with the opening 402b of the conduit 402. The regulating valve 500 is provided with a plug 501 by the plug 503. The glue 502 of the plug 501 is engaged with the opening 500e of the regulating valve 500.

[0142] Specifically, by opening a conduit 402, the total cavity 400a of the buffer structure 400 is connected to the outside. By setting an adjusting valve 500 outside the conduit, the rigidity of the buffer structure 400 is changed. For example, when the adjusting valve 500 is rotated to the misalignment of the adapter hole 500b and the opening 402b, each cavity is independently closed, and the support 401 is in the maximum rigidity state. Subsequently, as the adapter hole 500b and the opening 402b gradually become misaligned, its rigidity gradually decreases (its rigidity state can be adjusted by setting a scale on the adjusting valve 500). The plug 501 set on the adjusting valve 500 serves to maintain the maximum rigidity of the buffer structure 400 during the thermal expansion of the metal plate during welding. After welding, when the temperature is at its maximum and the stress of the metal plate is at its maximum, the displacement of the metal plate breaks through the plug 501 and releases pressure through the misalignment gap between the adapter hole 500b and the opening 402b. The metal plate exhibits a non-linear state during the thermal expansion and displacement process of welding. This process improves the traditional buffering method and is conducive to improving the uniform displacement of the metal plate during welding, thereby improving the yield and accuracy of the metal plate welding process.

[0143] In another embodiment compared to Example 1, a medium with a higher density, such as pressure relief oil, can be flushed in through conduit 402, and the regulating valve 500 can be sealed by plug 501. By setting the positions of the adapter hole 500b and the opening 402b close to the buffer structure 400, the buffer structure 400 is compressed during pressure relief, and the medium oil flows through the staggered gap between the adapter hole 500b and the opening 402b. The nonlinear buffering effect is achieved through the sealing form, and the misalignment of the adapter hole 500b and the opening 402b enables the regulating valve 500 to rotate to the misalignment of the adapter hole 500b and the opening 402b. Each cavity is independently closed, and the buffer structure 400 is in a state of maximum rigidity. This method can effectively prevent the plastic deformation of the buffer structure 400.

[0144] It is worth mentioning in conjunction with Embodiments 1 and 2 that the displacement distance during metal plate welding is relatively small, usually affected by factors such as the thickness of the material plate, and its range is between 1-10mm. Therefore, the buffer structure 400 can be designed with a thickness of 10mm to reduce the volume of the first cavity 400a-1, the second cavity 400a-2, and the third cavity 400a-3, thereby structurally achieving the fixation of the metal plate by the pure gasket during welding. The rigidity of the buffer structure 400 is improved by connecting the external conduit 402 and sealing the conduit 402 by plugging 501.

[0145] When pressure relief is required, 1. Micro-holes 401a are opened in the support member 401 inside the buffer structure 400 to allow the medium to flow between the second cavity 400a-2 to achieve buffering. 2. The reaction force of the buffer is further reduced by the misalignment of the conduit 402 and the adapter hole 500b with the opening 402b, and the medium discharge is used to offset the buffer and achieve a uniform buffering effect to improve the welding quality of the metal plate. 3. The buffer structure 400 is sealed by adding a plug 501 to the regulating valve 500, so that the rigidity of the buffer structure 400 is maintained before the metal plate is depressurized to ensure the fixed support of the buffer structure 400 for the metal plate. After the pressure relief value approaches the critical value, the plug 501 is discharged. 4. A medium oil with a higher density is injected into the buffer structure 400 and the conduit before sealing the plug 501. The buffering is achieved by the medium oil flowing in the second cavity 400a-2 and the third cavity 400a-3.

[0146] In this embodiment, the buffer structure 400 can switch between rigid and flexible support for the metal plate, especially the automatic morphological switching based on the thermal expansion and displacement of the metal plate during the welding process, as well as the manual switching of the buffer structure 400 between rigid and flexible support for the metal plate.
