Description

The present invention belongs to the technical field of supply devices, and specifically relates to a double-channel online high-speed automatic welding supply device and a continuous supply method.

In the actual manufacturing process of the continuous roll-type surface treatment production line in the electronics industry, on the premise of ensuring the quality of the surface treatment product, improving the speed of the surface treatment production line and effectively improving the efficiency of surface treatment production become important tasks in the field of surface treatment production. When the continuous roll surface treatment production line runs at a high speed of 20-70 m/min, the joining process of the tail of the previous strip material and the head of the following strip material will cause the following problems in the commonly used manual operation: 1. The accuracy of manual joining is low, and the positioning hole of the product cannot be accurately overlapped, so that the product does not match the positioning hole of the jig. 2. The joining is often connected by rivets, and the connection of the end is easy to be weak, so there is a risk that the rivets will be scattered and rubbed against the guide jig of the process groove. 3. The products on the strip material are very small and thin, so they are easily deformed in the manual joining operation, which affects the quality of the product. 4. The manual joining of the product is not firm and is easy to fall off during high-speed production. 5. If the joining operation takes a long time and the joining is not completed in a timely manner, there is a risk that the surface treatment production line will automatically stop. 6. In joining operations, improper manual handling can cause work accidents in which the raw material injures the worker's hands.
