Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for household appliances with a protective mechanism. Background Technology

[0002] In modern life, home appliances have long been an indispensable part, greatly improving the convenience and comfort of life. From the kitchen to the living room, from the bedroom to the bathroom, they are found in every corner of the home, helping to complete various housework and comprehensively improving the quality of life. As an important category of appliances, home appliances cover all kinds of equipment needed in daily life. At present, most factories only produce appliances of a single specification, and casing welding is a necessary step in the production process. Usually, workers need to use jigs to position and fix them, but due to the large amount of processing, frequent adjustment of jigs and handling of casings is not only time-consuming and laborious, but also seriously reduces the processing speed and efficiency. During welding, workers need to wear a lot of protective equipment, which restricts their movement to a certain extent. If high-end automatic welding robots are used to weld the casings of these simple appliances of a single specification, the cost will be too high. Summary of the Invention

After placement, the motor inside the control motor box B402 is started. The motor controls the rotation of the threaded rod A4012. During the rotation, the threads on the surface of the threaded rod A4012 can control the sliding frame 4013 to slide. The sliding frame 4013 and the two sets of driving toothed plates 4014 at the upper and lower ends slide simultaneously. The bottom set of control screws 403 is rotated under control. During the rotation, the two sets of threads on the surface of the control screw 403 in opposite directions can control the two sets of sliding support plates 201 to slide inward. The two sets of sliding support plates 201 drive the auxiliary pushing roller 2 04. Contacting the appliance casing and applying a pushing force, the appliance is pushed to the middle position, completing automatic positioning.

After positioning, the motor inside the motor box 303 starts, and the motor controls the rotation of the main control rod 302. Since the gear on the surface of the main control rod 302 is connected to the two sets of rotating rods B3 through the gear belt 304, 05 Rotary connection, two sets of rotating rods B305 rotate simultaneously. Rotating rods B305 are rotatably connected to connecting rotating rod 306 via bevel gear assembly. Connecting rotating rod 306 drives connecting rod 206 to rotate via driving rod B307. Since driving rod B307 slides into the hexagonal groove of connecting rotating rod 306, it can complete telescopic sliding and also perform transmission rotation. Connecting rod 206 rotates, and connecting rod 206 controls driving rod A202 to rotate via bevel gear assembly. Driving rod A202 controls multiple sets of rotating rods A203 and auxiliary pushing roller 204 to rotate via bevel gear assembly, and transports the electrical housing to below the protective transparent baffle 601. The receiving machine 7 passes through the elastic baffle 603 and inserts into the protective transparent baffle 601 to weld the conveyed shell. After welding, the contact conveying mechanism 2 controls the electrical shell to separate from the support mechanism 1, completing the rapid welding of the assembly line. The motor box B402 controls the threaded rotating rod A4012 to rotate in the opposite direction, the sliding support plate 201 slides outward, and the gear belt 304 rises to facilitate the subsequent sliding of the electrical shell. The forward and reverse rotation of the threaded rotating rod B502 can also control the rotating rod D604 to rotate accordingly.
