Description

Technical Field

[0001] The utility model relates to the technical field of display back panel production, in particular to a punching device for producing an LED display back panel. Background Art

[0002] The back panel of the LED display is an important component of the display. The back panel of the LED display is produced by multi-stage stamping and step-by-step processing. Multiple groups of molds work together, and the transmission device transfers the back panel one by one. After the waste of the back panel is punched and cut, the electric suction cup removes the back panel and the waste together, and then the waste falls automatically. Some factories use manual rivets to place rivets inside the back panel in the gap between the back panels. The mold operation is fast, and the workers do not have much time to operate. The workers are required to have high concentration, and there is a risk of injury to the workers. It is not convenient to automatically place rivets. Moreover, the punching effect of some molds decreases after being used for a long time, and some waste is not punched completely. After being removed, it may not be completely separated from the back panel. If the transmission unit transfers the back panel together with the waste to the inside of the next mold, it may cause damage to the mold, which is not convenient for assisting the separation of the waste from the back panel and inconvenient to use.
