Description

Technical Field

[0001] The utility model generally relates to the technical field of metal processing, and in particular to an automatic plate and strip welding device. Background Art

[0002] During the surface processing of the plate and strip, in order to remove the oxide layer, rust, pollutants and grease on the surface of the plate and strip, so as to improve the cleanliness and brightness of the surface of the plate and strip, the plate and strip need to be acid-free treated. The long strip of plate and strip is flattened and passed through the continuously arranged grinding and brushing units, and is polished by rollers covered with brush strips. The plate and strip are in a flattened state in the grinding and brushing units. Usually, the rollers are arranged on the upper and lower surfaces of the flattened plate and strip. In order to prevent the plate and strip from bending, rollers are also provided for support.

[0003] In the acid-free treatment, it takes a long time to start and stop many grinding and brushing units, and due to the harsh processing environment, the start and stop operation of the grinding and brushing units is not only laborious, but also harmful to the health of the workers. Therefore, in order to ensure that the grinding and brushing units are not simply operated, the plate strips to be processed need to be spliced ​​into a complete and uninterrupted plate strip, so that the grinding and brushing units can not simply operate to complete the processing of the plate strips to be processed at one time. Most of the existing plate strip splicing devices are two clamping devices set on the workbench. The two clamping devices clamp the head and tail of the two plates and strips respectively, and use mechanical scissors to cut the splicing surface of the head and tail so that the head and tail can be aligned. After moving the clamping device and splicing the head and tail together, the staff manually welds the two plates and strips together with a welding gun to complete the plate strip splicing.

[0004] This solution has the following defects: workers are required to perform welding manually, the overall operation process is cumbersome and inefficient, and the strong light and smoke generated during welding will also pose a threat to the health of workers. Summary of the invention
