[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Please see Figure 1-3 As shown, a welding device for sheet metal processing includes a worktable 1, a PLC controller 2 mounted on the worktable 1, a placement plate 3 rotatably mounted on the worktable 1, and a clamping assembly mounted on the placement plate 3. The clamping assembly includes a first electromagnetic plate 301. A first placement groove is formed in the placement plate 3, and the first electromagnetic plate 301 is fixedly installed in the first placement groove. Four sets of guide seats 302 are mounted on the side wall of the placement plate 3. Guide grooves are formed on the guide seats 302, and sliding rods 303 are assembled in the guide grooves. A limit plate 304 is installed at one end of the sliding rod 303. A second placement groove is formed in the limit plate 304, and a second electromagnetic plate 305 is fixedly installed in the second placement groove. A threaded hole is formed on the guide seat 302, and a fixing screw is assembled in the threaded hole. 306, a knob 307 is installed on the fixing screw 306, and a drive motor 308 is installed on the workbench 1 through the machine base. The output shaft of the drive motor 308 is fixedly connected to the rotating shaft on the placement plate 3. Sheet metal parts 8 are placed on the placement plate 3. During operation, the existing welding device needs to splice the metal plates into a box structure in order to perform efficient welding, but it is difficult to quickly and conveniently assemble and position the sheet metal parts 8, resulting in poor positioning convenience of the sheet metal parts 8. Sheet metal parts 8 refer to metal parts or components with certain shapes, sizes and functions processed by sheet metal processing technology, such as cutting, bending, stamping, welding, etc. In this case, multiple metal plates need to be welded and combined into a cabinet.
[0020] The PLC controller 2 powers the first electromagnetic plate 301 and the four second electromagnetic plates 305. The coils inside the first electromagnetic plate 301 and the four second electromagnetic plates 305 generate magnetic fields, which magnetically attract the metal plates they contact. By placing the base plate of the sheet metal part 8 on the first electromagnetic plate 301, the first electromagnetic plate 301 stably attracts and fixes the base plate of the sheet metal part 8. Then, the four side plates are assembled sequentially. During this process, after the side plates are assembled with the base plate, the limiting plate 304 next to the side plate is moved to contact the side plate, and the second electromagnetic plate 305 on it quickly magnetically fixes the side plate. Then, the guide seat 302 is rotated. The knob 307 on the upper part drives the fixing screw 306 to rotate. The fixing screw 306 is screwed into the threaded hole to press and fix the sliding rod 303 on the limiting plate 304, thereby fixing the limiting plate 304 and the second electromagnetic plate 305. This achieves the rapid fixing of the side plate of the sheet metal part 8. Repeat the above steps to fix the other three side plates, achieving the rapid splicing and fixing of the four side plates and the bottom plate. This structure does not use mechanical clamps, avoiding damage to the metal sheet caused by clamping force. By using the electromagnetic plate, the metal plate can be magnetically positioned efficiently and conveniently, which helps to improve the convenience of positioning the sheet metal part 8.
[0021] Please see Figure 4-5As shown, an adjustment assembly is installed on the workbench 1. The adjustment assembly includes a first guide plate 4, a first moving groove 401 is formed inside the first guide plate 4, a first stepper motor 402 is mounted on the side wall of the first guide plate 4 via a base, a first lead screw 403 is mounted on the output shaft of the first stepper motor 402, the first lead screw 403 is rotatably mounted on the inner wall of the first moving groove 401, a first moving block 404 is assembled inside the first moving groove 401, a support rod 5 is mounted on the first moving block 404, and a... A second guide plate 6 has a second moving groove 601 inside. A second stepper motor 602 is mounted on the side wall of the second guide plate 6 via a base. A second lead screw 603 is mounted on the output shaft of the second stepper motor 602. The second lead screw 603 is rotatably mounted on the inner wall of the second moving groove 601. A second moving block 604 is assembled inside the second moving groove 601. A welding assembly is mounted on the second moving block 604. The welding assembly includes a connecting seat 7, which is fixedly connected to the second moving block 604. An electric cylinder 701 is installed on the top, a connecting frame 702 is installed on the rod of the electric cylinder 701, a camera 703 is installed on the connecting frame 702, a welding torch 704 is installed on the connecting frame 702, and welding wire 705 is placed on the welding torch 704. During operation, the existing welding device has difficulty in performing continuous multi-sided welding on the sheet metal part 8, resulting in poor welding efficiency. After the four side plates are spliced and fixed to the base plate, the drive motor 308 is controlled by the PLC controller 2 to operate. The drive motor 308 drives the placement plate 3 to rotate, and the placement plate 3 drives the sheet metal part 8 on it to rotate. The camera 703 is an Oryx ORX-10G-51S5M camera. The camera 703 captures the sheet metal part 8 in real time. The camera 703 converts the optical image into an electronic signal and sends the signal to the PLC controller 2. When the weld seam of the sheet metal part 8 is relative to the position of the welding gun 704, the PLC controller 2 controls the drive motor 308 to stop operating, thereby realizing the angle adjustment of the sheet metal part 8.
[0022] By adjusting the operation of the components, specifically by operating the first stepper motor 402, the second lead screw 603 is driven to rotate. The second lead screw 603 drives the first moving block 404 to move horizontally. The first moving block 404 drives the support rod 5 to move horizontally. The support rod 5 drives the second guide plate 6 to move horizontally. The second guide plate 6 drives the welding torch 704 and camera 703 on it to move horizontally in the X-axis direction. Similarly, by operating the second stepper motor 602, the second lead screw 603 is driven to rotate. The second lead screw 603 drives the second moving block 604 to move horizontally. The second moving block 604 drives the connecting seat 7 to move horizontally. The connecting seat 7 drives the welding torch 704 and camera 703 on it to move horizontally in the Y-axis direction. The structure enables horizontal movement of the welding torch 704 and camera 703 in the X and Y axes. The electric cylinder 701 operates, and its actuator drives the connecting frame 702 to move vertically. The connecting frame 702 then drives the welding torch 704 and camera 703 to move vertically in the Z axis direction. This structure allows the welding torch 704 and camera 703 to move in the X, Y, and Z axes. Based on the real-time capture of the sheet metal part 8 by the camera 703, the PLC controller 2 controls the welding torch 704 to weld along the weld seam of the sheet metal part 8. This means it automatically identifies the weld seam position and adjusts the path in real time, and can continuously weld multiple weld seams on the sheet metal part 8, thus improving welding efficiency.
[0023] Working principle: In the process of welding sheet metal parts 8, the existing welding equipment needs to splice the metal plates into a box structure in order to perform efficient welding. However, it is difficult to quickly and conveniently assemble and position the sheet metal parts 8, resulting in poor positioning convenience of the sheet metal parts 8. Sheet metal parts 8 refer to metal parts or components with certain shapes, sizes and functions processed by sheet metal processing technology, such as cutting, bending, stamping, welding, etc. In this case, multiple metal plates need to be welded and combined into a cabinet.
[0024] The PLC controller 2 powers the first electromagnetic plate 301 and four second electromagnetic plates 305. The coils inside the first electromagnetic plate 301 and the four second electromagnetic plates 305 generate magnetic fields, which magnetically attract the metal plates they contact. By placing the base plate of the sheet metal part 8 on the first electromagnetic plate 301, the first electromagnetic plate 301 stably attracts it, thus fixing the base plate of the sheet metal part 8. Then, the four side plates are assembled sequentially. During this process, after the side plates are assembled with the base plate, the limiting plate 304 next to the side plate is moved to contact the side plate. The second electromagnetic plate 305 on it quickly magnetically fixes the side plate. Then, the knob 307 on the guide seat 302 is rotated, causing the fixing screw 306 to rotate. The fixing screw 306 screws into the threaded hole and presses and fixes the sliding rod 303 on the limiting plate 304, thus fixing the limiting plate 304. The second electromagnetic plate 305 is fixed, thus achieving rapid fixing of the side plates of sheet metal part 8. Repeating the above steps, the other three side plates are fixed, achieving rapid splicing and fixing of the four side plates and the base plate. This structure does not use mechanical clamps, avoiding damage to the thin metal sheet caused by clamping force. Using electromagnetic plates, the metal sheet can be magnetically positioned efficiently and conveniently, improving the ease of positioning sheet metal part 8. Existing welding devices struggle to perform continuous multi-sided welding on sheet metal part 8, resulting in poor welding efficiency. After the four side plates are spliced and fixed to the base plate, the PLC controller 2 controls the drive motor 308 to operate. The drive motor 308 drives the placement plate 3 to rotate, which in turn drives the sheet metal part 8 on it to rotate. The camera 703 is an Oryx model. The ORX-10G-51S5M camera 703 captures the sheet metal part 8 in real time. The camera 703 converts the optical image into an electronic signal and sends it to the PLC controller 2. When the weld seam of the sheet metal part 8 is aligned with the welding torch 704, the PLC controller 2 stops the drive motor 308, thus adjusting the angle of the sheet metal part 8. The adjustment mechanism operates by means of the first stepper motor 402, which drives the second lead screw 603 to rotate. The second lead screw 603 then moves the first moving block 404 horizontally. The support rod 5 moves horizontally, which in turn moves the second guide plate 6 horizontally. The second guide plate 6 then moves the welding torch 704 and camera 703 on it horizontally in the X-axis direction. The second stepper motor 602 rotates the second lead screw 603, which in turn moves the second moving block 604 horizontally. The second moving block 604 then moves the connecting seat 7 horizontally, which in turn moves the welding torch 704 and camera 703 on it horizontally in the Y-axis direction. This achieves horizontal movement of the welding torch 704 and camera 703 in the X and Y axes.The electric cylinder 701 operates, and its actuator rod drives the connecting frame 702 to move vertically. The connecting frame 702 then drives the welding torch 704 and camera 703 to move vertically in the Z-axis direction. This structure enables the welding torch 704 and camera 703 to move in the X, Y, and Z-axis directions. Based on the real-time capture of the sheet metal part 8 by the camera 703, the PLC controller 2 controls the welding torch 704 to weld along the weld seam of the sheet metal part 8. This means it automatically identifies the weld seam position and adjusts the path in real time, and can continuously weld multiple weld seams on the sheet metal part 8, thus improving welding efficiency.
