Then, the third cylinder is controlled to extend, so that the two pressure rods move relative to each other. Then, the second cylinder is controlled to retract, so as to press the metal film onto the frame. Then, the slide is controlled to move by the linear displacement mechanism, so that the edge of the metal film is welded to the frame by the welding mechanism. After the welding is completed, the pressure rods are moved away from the frame and the metal film. Then, the first rotating shaft is controlled to rotate by the second drive mechanism, so that the frame rotates and wraps the metal film. After one turn, the pressure rods press the metal film onto the frame again. Then the metal film is cut. The slide is controlled to move again, and the welding mechanism welds the cut edge of the metal film back to the frame, thus completing the welding and greatly improving the welding efficiency.

Detailed Implementation
[0024] 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 protection scope of the present utility model.
[0025] Example 1
[0026] Please see Figures 1-4 A straight seam welding machine for metal film welding includes a casing 1. Two first wall plates 2 are connected to both sides of one end of the casing 1. Take-up and release wheels 3 are rotatably connected to the two first wall plates 2. The take-up and release wheels 3 are used to wind the metal film. One of the first wall plates 2 is equipped with a first drive mechanism to drive the take-up and release wheels 3 to rotate. Specifically, the first drive mechanism consists of a first motor 17 mounted on one of the first wall plates 2, a first transmission shaft connected to the first motor via a coupling, a drive wheel 18 connected to the first transmission shaft, and a driven wheel 19 connected to one end of the take-up and release wheels. The drive wheel 18 and the driven wheel 19 are connected by a transmission belt. When the first motor 17 operates, it drives the first transmission shaft to rotate. Through the cooperation of the drive wheel 18, the driven wheel 19, and the transmission belt, the take-up and release wheels 19 are driven to rotate, thereby releasing the metal film.
[0027] The other end of the chassis 1 is connected to two second wall plates 4. A linear displacement mechanism is provided on the upper part of the two second wall plates 4, and a slide block 5 is connected to the linear displacement mechanism. The linear displacement mechanism can drive the slide block to move linearly. Specifically, the linear displacement mechanism includes a lead screw 20 rotatably connected to the two second wall plates, guide rods 21 mounted on the two second wall plates and located on both sides of the lead screw, and a second motor 22 mounted on one of the second wall plates and driven by the lead screw. The slide block 5 is threadedly connected to the lead screw 20, and the slide block 5 is slidably connected to the guide rods 21. When the second motor 22 operates, it drives the lead screw 20 to rotate, and during the rotation of the lead screw 20, it drives the slide block 5 to move linearly along the guide rods 21.
[0028] A welding mechanism is mounted on the bottom surface of the slide block 5. When the slide block 5 moves linearly, it drives the welding mechanism to move together. Specifically, the welding mechanism includes an L-shaped mounting plate 26 fixedly connected to the bottom surface of the slide block, a fourth cylinder 27 mounted on the mounting plate, and a welding torch 28 connected to the extension end of the fourth cylinder. By controlling the extension of the fourth cylinder 27, the welding torch 28 contacts the frame and the metal film, enabling welding between the metal film and the frame.
[0029] Two support plates 6 are connected between the two second wall panels 4 on the chassis 1. A first rotating shaft 7 is rotatably connected to one of the support plates 6, and a second drive mechanism for driving the first rotating shaft 7 is provided on the support plate 6. The second drive mechanism includes a third motor 23 mounted on one of the support plates, a second transmission shaft connected to the third motor via a coupling, a main gear 24 connected to the second transmission shaft, and a secondary gear 25 connected to the first rotating shaft. The main gear 24 and the secondary gear 25 mesh. By controlling the operation of the third motor 23, the first rotating shaft 7 can be driven to rotate. A first cylinder 8 is mounted on the other support plate 6. The telescopic end of the first cylinder 8 is rotatably connected to a second rotating shaft 10 via a rotary joint 9. Pneumatic chucks 11 are mounted on the opposite ends of the first rotating shaft 7 and the second rotating shaft 10. L-shaped clamping rods 12 are connected to the jaws of the pneumatic chucks 11. The welding torch 28 is located above the space between the two support plates 6. When fixing the frame, firstly, one end of the frame is fitted onto the clamping rod 12 of the pneumatic chuck on one side of the first rotating shaft 7. Then, the first cylinder 8 is extended, pushing the clamping rod 12 on the other pneumatic chuck into the other end of the frame. Then, the jaws of the two pneumatic chucks 11 are controlled to move outwards, thereby driving the clamping rod 12 outwards until it is pressed tightly against the inner wall of the frame, thus completing the fixing of the frame. The pneumatic chuck is existing technology, and its specific structure and principle will not be described in detail in this embodiment.
[0030] A second cylinder 13 is vertically mounted on both the first rotating shaft 7 and the second rotating shaft 10. A lifting plate 14 is connected to the telescopic end of the second cylinder 13, and a third cylinder 15 is mounted on the lifting plate 14. The two third cylinders 15 are positioned opposite each other, and pressure rods 16 are connected to the opposite ends of each third cylinder 15. When one side of the metal film is positioned on the frame, the third cylinder 15 is first extended so that the pressure rods 16 are positioned above both ends of the frame. Then, the second cylinder 13 is retracted, pressing the metal film onto the frame through the pressure rods 16, thereby fixing the edge of the metal film to the frame.
[0031] The working principle of this embodiment is as follows: The clamping rods 12 on the two pneumatic chucks 11 are inserted into both ends of the frame 31, and the frame 31 is fixed by the clamping rods 12. Then, the metal membrane 32 is released by the retracting wheel 3. At this time, the metal membrane 32 can be manually pulled to bring its edge into contact with the frame 31. Then, the third cylinder 15 is controlled to extend, causing the two pressure rods 16 to move relative to each other and be positioned above both ends of the frame 31. Next, the second cylinder 13 is controlled to retract, causing the pressure rods 15 to descend and press the edge of the metal membrane 32 onto the frame 31. The slide block 5 is moved by a linear displacement mechanism, and the edge of the metal film is welded to the frame by a welding mechanism. After welding, the pressure rod 16 is separated from the frame and the metal film. Then, the first rotating shaft 7 is rotated by the second drive mechanism, which drives the frame to rotate and wrap the metal film. After wrapping once, the pressure rod 16 presses the metal film onto the frame. Then, the metal film is cut, and the slide block 5 is moved again. The cut edge of the metal film is then welded to the frame by the welding mechanism, thus completing the welding and greatly improving the welding efficiency.
[0032] The metal film can be cut manually or by using a robotic arm with a cutting tool. The cutting is achieved through the cooperation of the robotic arm and the cutting tool. The robotic arm is existing technology, and the cutting tool can be a blade. Mounting a blade on the robotic arm is also existing technology, and will not be described in detail in this embodiment.

[0034] The difference between this embodiment and embodiment 1 is that an extension plate 29 is connected to the side of the two second wall panels 4 near the take-up and take-down wheels, and two guide rollers 30 arranged vertically are rotatably connected to the two extension plates 29.
[0035] The two guide rollers guide the metal film to facilitate its winding onto the skeleton.
