Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to an intelligent fixed welding machine for furniture production. Background Art

[0002] In the modern furniture manufacturing industry, stainless steel is widely used in the production of various cabinet structures due to its good corrosion resistance, strength and beautiful appearance. Among them, welding, as a key process link in the assembly process of stainless steel cabinets, plays a decisive role in product quality and structural stability.

[0003] The existing stainless steel cabinet welding process relies heavily on manual operation, especially during the spot welding stage. Workers need to place the cut stainless steel plates according to the design drawings, then hold the plates steady with one hand while using the welding torch to perform spot welding for initial fixation. During this process, the operator needs to move along the welding path while taking into account both the positioning of the plates and the control of the welding torch. However, since manual support of the plates cannot guarantee absolute stability, especially when welding long seams or at multiple angles, the plates are easily affected by external forces or the reaction force of the welding torch, causing displacement or vibration. This can cause the plate joint angle to deviate from the design requirements, ultimately affecting the geometric accuracy of the cabinet structure. Summary of the Invention

[0004] In view of this, the present invention provides an intelligent fixed welding machine for furniture production, which can overcome the shortcomings of existing welding machines that rely on workers to manually fix stainless steel plates when welding stainless steel cabinets, and it is difficult for workers to ensure the absolute stability of the plates when moving along the welding path, resulting in displacement or vibration of the plates.

The first motor 15 is provided at the front left side of the fixing frame 1 on the lower side. The second motor 16 is installed on the output shaft of the first motor 15. The connecting plate 17 is connected to the output shaft of the second motor 16. The sliding sleeve 18 is connected to the top of the connecting plate 17.

[0030] When two stainless steel plates need to be welded and fixed, first swing the rotating rod 5 up and down according to the installation angle requirements of the two stainless steel plates on the design drawings. The rotating rod 5 can drive the fixing frame 1 and the connecting plate 13 on the left to rotate with the rotation axis of the rotating rod 5 as the rotation center. When the scale value on the marking rod 14 pointing to the connecting plate 13 is consistent with the value of the installation angle, stop swinging the rotating rod 5 and rotate the locking bolt 12 to move the locking bolts 12 on the front and rear sides away from each other until the end of the locking bolt 12 contacts the side of the connecting plate 13. The friction between the locking bolt 12 and the connecting plate 13 is used to tighten the connection. The disc 13 is locked, thereby locking the rotating rod 5 and the fixed frame 1 on the left, so that the angle between the two fixed frames 1 is consistent with the installation angle of the two stainless steel plates; then, according to the length of the welding path of the stainless steel plate, the first switch 9 can be pressed once, and the first switch 9 controls the first electric slide rail 2 to start working, and the first electric slide rail 2 will drive the movable frame 3 to move backward. When the movable frame 3 moves backward to a suitable distance, the first switch 9 is pressed again, and the first switch 9 controls the first electric slide rail 2 to stop working. In this way, the distance between the fixed frame 1 and the movable frame 3 can be adjusted to adapt to stainless steel plates of different lengths for use; then Then the worker places the two stainless steel plates according to the requirements of the design drawings, and then places the device on one of the stainless steel plates so that the bottom of the lower fixed frame 1 and the movable frame 3 are in contact with the top of the stainless steel plate. Then, the worker holds the handle 8 and moves the device toward the other stainless steel plate until the left side of the fixed frame 1 and the movable frame 3 are in contact with the side of the other stainless steel plate. Then, the worker presses the second switch 10 again. The second switch 10 controls the servo motor 7 to start working. The servo motor 7 drives the knob of the switch magnetic base 6 to rotate a certain angle to control the switch magnetic base 6 to open, so that the four switch magnetic bases 6 respectively attract the two stainless steel plates. Steel plate, thereby fixing the position of the two stainless steel plates, preventing relative movement or shaking between the two stainless steel plates; then the second motor 16 drives the connecting plate 17 to rotate, and the connecting plate 17 can drive the sliding sleeve 18 and the laser welding gun 19 to rotate up and down, so that the laser welding gun 19 is aligned with the position where the two stainless steel plates need to be welded, and then the second electric slide rail 26 drives the first motor 15 to move along the welding path of the two stainless steel plates, driving the laser welding gun 19 to move along the welding path of the two stainless steel plates, and at the same time starting the laser welding gun 19, so that the two stainless steel plates can be welded and fixed by the laser welding gun 19;Since the length of the second electric slide rail 26 is consistent with the length of the fixed frame 1, the moving distance of the laser welding gun 19 will be limited. Therefore, when the laser welding gun 19 moves to the rearmost side of the second electric slide rail 26, the second electric push rod 24 will drive the sliding tube 25 to move backward a specified distance, which is consistent with the distance that the above-mentioned moving frame 3 moves backward. The sliding tube 25 can drive the second electric slide rail 26 and the laser welding gun 19 to move backward, so that the laser welding gun 19 can fully weld the two stainless steel plates to ensure a good welding effect; when the four sides of a stainless steel plate need to be welded to other stainless steel plates, the horizontal movement range of the laser welding gun 19 will be limited, resulting in the corner position between the three stainless steel plates cannot be welded in place, so when the laser welding gun 19 moves horizontally until it contacts the side of one of the stainless steel plates, the second motor 16 can be driven by the first motor 15 to The laser welding gun 19 rotates horizontally, driving it to rotate horizontally so that it can align with the corner position between the three stainless steel plates. Since the horizontal rotation of the laser welding gun 19 increases the distance between it and the corner position, the second electric push rod 24 drives the connecting block 21 and the connecting ring 22 to move closer to the corner while the laser welding gun 19 rotates horizontally, driving the laser welding gun 19 to move closer to the corner to focus the laser welding gun 19. After welding is completed, the second switch 10 is pressed again. The second switch 10 controls the servo motor 7 to start working. The servo motor 7 drives the knob of the switch magnetic base 6 to reverse a certain angle to control the switch magnetic base 6 to close, so that the switch magnetic base 6 releases the stainless steel plate. The first electric slide rail 2 then drives the movable frame 3 to move forward and reset. Finally, the device can be removed from the stainless steel plate.

[0031] like Figure 7-Figure 9 As shown, it also includes a vertical tube 27, a connecting spring 28, a ball 29 and a magnet 31. The two fixed frames 1 and the two mobile frames 3 are symmetrically slidably connected with two vertical tubes 27. A connecting spring 28 is wound around the outside of each vertical tube 27, and one end of the connecting spring 28 is connected to the vertical tube 27, and the other end of the connecting spring 28 is connected to the fixed frame 1 and the mobile frame 3 respectively. One end of each vertical tube 27 is rotatably connected to the ball 29. The fixed frame 1 and the mobile frame 3 on the left are both provided with vertical slots 30, and magnets 31 are connected to the two vertical slots 30.

[0032] When the device is placed on a stainless steel plate, the ball 29 on the lower side will contact the surface of the stainless steel plate. The ball 29 can reduce the friction between the fixed frame 1 and the movable frame 3 and the stainless steel plate, making it easier for the device to move on the stainless steel plate. When the fixed frame 1 and the movable frame 3 on the left move to the left, they can drive the magnet 31 and the ball 29 on the left to move to the left. When the magnet 31 approaches the other stainless steel plate, the magnet 31 can guide the fixed frame 1 and the movable frame 3 on the left to move to the left through magnetic force, ensuring that the ball 29 on the left can all contact the side of the other stainless steel plate, so that the fixed frame 1 and the movable frame 3 on the left remain parallel to the other stainless steel plate. When the switch magnetic base 6 attracts the stainless steel plate, the vertical tube 27 and the ball 29 will be compressed and retracted, and the connecting spring 28 is compressed, so that the sides of the fixed frame 1 and the movable frame 3 fit against the sides of the stainless steel plate, ensuring the stability of the stainless steel plate.
