Description

Technical Field

[0001] The invention relates to the technical field of automatic welding equipment, and in particular to an automatic welding equipment for edge-wrapped water tanks and a welding method thereof. Background Art

[0002] The edge-wrapped gutter is a type of gutter used in specific fields. It is commonly seen in the photovoltaic industry and the construction field. In buildings such as photovoltaic sun rooms, the edge-wrapped gutter is usually used to clamp the collar strip or inclined beam to ensure that the two sides of the sun room will not leak, and it plays a role in waterproofing and drainage. In terms of materials, metal materials such as aluminum-zinc-magnesium are mostly used, which have good corrosion resistance. In the field of metal processing, the forming and production of edge-wrapped gutter is an important link, including one-time forming method and welding method. Since the one-time forming method is to punch a gutter out of a whole piece of sheet material, it has high requirements on equipment and molds. It is necessary to use 0.8-1mm thick plates and integral molds, and imported stamping equipment. Although there is no problem of weld leakage, the edge of the plate is cut and lost, and the investment in molds and equipment is high, and the cost is also high. Therefore, most manufacturers use welding to produce edge-wrapped gutter. The existing welding method is usually that the welder fixes one side plate of the edge-wrapped gutter on the workbench, and then holds the bottom plate and manually welds along the edge of the side plate to complete the welding and forming of the edge-wrapped gutter.

[0003] However, the welding efficiency of the existing welding forming method is low. As labor costs continue to rise, production costs also increase. Long-term welding work makes workers easily fatigued, further reducing work efficiency and increasing the risk of producing waste.

[0004] Therefore, an automatic welding device for an edge-wrapped water tank and a welding method thereof are proposed to solve the above problems. Summary of the invention

At this time, the side plates on both sides are respectively placed in the vertically arranged clamping drive assembly, and then the threaded column one is rotated to drive the limit block to slide on the inner cavity surface of the T-shaped frame, so that the clamping drive assembly clamps the side plate, and then the clamping drive assembly is started to drive the side plate to move, so that one end of the side plate fits on the L The outer surface of one side of the baffle is a T-shaped baffle. After the side panel is installed, turning valve 1 drives the positive and negative screw rods 2 to rotate. The rotation of the positive and negative screw rods 2 drives the two T-shaped frames symmetrically threaded on the outer surfaces thereof to slide on the inner surface of the base, thereby driving the two side panels to move relative to each other, so that the upper edges of the two side panels are fitted with the two side edges of the bottom plate.

[0026] 3. The present invention sets up an automatic welding assembly, including a motor 1, which rotates the threaded column 2 to drive the mounting block whose outer surface is threadedly connected to slide on the inner surface of the hollow frame 2. The sliding of the mounting block drives the welding head to move synchronously, and then starts the motor 1 to drive the threaded screw 2 to rotate. The rotation of the threaded screw 2 drives the connecting block whose outer surface is threadedly connected to slide on the inner surface of the guide frame, thereby driving the hollow frame 2 to move, and then drives the welding head to perform linear welding along the edges of the bottom plate and the side plates. Utilizing the above structure, the welding head is driven to move linearly by starting the motor 1, thereby realizing the automatic welding of the hemmed water tank, improving the welding quality, reducing the labor of the staff, and thus greatly reducing the labor cost.

[0050] A method for welding a hemmed water tank, using the welding equipment according to any one of claims 1 to 9 to weld the hemmed water tank, the welding method comprising:

[0051] S1 Bottom plate installation: Place the bottom plate inside the clamping drive assembly 5, rotate the forward and reverse screw rods 23 to drive the bottom plate to fit on the outer surface of the driving roller 54, then start the motor 57 to drive the worm 56 to rotate, so that the bottom plate is located at the center of the mounting plate 51, then rotate the valve 38 to drive the threaded screw rod 37 to rotate, so that the vertical surface of the L-shaped baffle 36 is perpendicular to one end surface of the bottom plate;

[0052] S2 Side panel installation: Rotate the threaded column 1 34 to drive the limit block 35 to slide, so that the clamping drive assembly 5 clamps the side panel, then start the clamping drive assembly 5 to drive the side panel to move, so that one end of the side panel fits on the outer surface of one side of the L-shaped baffle 36, and then rotate the valve 1 33 to drive the forward and reverse screw rods 2 31 to rotate, so that the upper side edges of the two side panels fit with the two side edges of the bottom plate;

[0053] S3 welding: rotating the threaded column 45 drives the mounting block 46 to slide, and the sliding of the mounting block 46 drives the welding head 47 to move synchronously, and then starting the motor 1 41 drives the threaded screw 2 42 to rotate, and the rotation of the threaded screw 2 42 drives the connecting block 43 to slide, thereby driving the hollow frame 2 44 to move, and then driving the welding head 47 to perform straight line welding along the edges of the bottom plate and the side plate.

[0054] Everything in the above example works like this:

[0055] First, place the bottom plate inside the clamping drive assembly 5, located on the outer surface of the roller shaft 52, and then rotate the positive and negative screw rods 23 to drive the two U-shaped sliders 24 symmetrically threaded on their outer surfaces to slide relative to each other, drive the connecting rod 25 to rotate, so that the mounting plate 51 moves upward, and drives the bottom plate to fit the outer surface of the driving roller 54. Then start the motor 2 57 to drive the worm 56 to rotate. The rotation of the worm 56 drives the worm wheel 55 meshing on its outer surface to rotate, and then drives the driving roller 54 to rotate, so that the bottom plate moves until it stops at the center position of the mounting plate 51. When the height of the bottom plate needs to be changed, continue to rotate the positive and negative screw rods 23 to drive the clamping drive assembly 5 to move vertically. After the bottom plate is installed, turn the valve 2 38 to drive the threaded screw rod 37 to rotate. The threaded screw rod 37 rotates. The L-shaped baffle 36 is driven to slide on the lower inner wall of the base 1, so that the vertical surface of the L-shaped baffle 36 is perpendicular to the end surface of the bottom plate. At this time, the side plates on both sides are respectively placed in the vertically arranged clamping drive assembly 5, and then the threaded column 1 34 is rotated to drive the limit block 35 to slide on the inner cavity surface of the T-shaped frame 32, so that the clamping drive assembly 5 clamps the side plate, and then the clamping drive assembly 5 is started to drive the side plate to move, so that one end of the side plate is attached to the outer surface of one side of the L-shaped baffle 36. After the side plate is installed, the valve 1 33 is rotated to drive the positive and negative screw rods 2 31 to rotate. The rotation of the positive and negative screw rods 2 31 drives the two T-shaped frames 32 whose outer surfaces are symmetrically threadedly connected to slide on the inner surface of the base 1, thereby driving the two side plates to move relative to each other, so that the upper edges of the two side plates are attached to the two side edges of the bottom plate.

[0056] Finally, rotate the threaded column 45 to drive the mounting block 46 threadedly connected to its outer surface to slide on the inner surface of the hollow frame 44. The sliding of the mounting block 46 drives the welding head 47 to move synchronously. Then start the motor 41 to drive the threaded screw 42 to rotate. The rotation of the threaded screw 42 drives the connecting block 43 threadedly connected to its outer surface to slide on the inner surface of the guide frame 28, thereby driving the hollow frame 44 to move, and then driving the welding head 47 to perform linear welding along the edges of the bottom plate and the side plates.
