[0002] Currently, LEDs are semiconductor devices, solid-state devices that can convert electrical energy into light energy. With advantages such as low power consumption, long life, fast response, and high brightness, LEDs are widely used in various lighting and display fields.

[0003] LED digital tubes are an application of LEDs, consisting of multiple LEDs that can display numbers, letters, and some symbols. Common LED digital tubes include seven-segment LED tubes, where each digit or character is composed of several LEDs, and the display function is achieved by controlling the LEDs' on and off states. LED digital tubes utilize the light-emitting properties of LEDs to display information in digital form. They are commonly found in devices such as timers, counters, and temperature displays.

[0004] After LED digital tubes are manufactured, they need to be covered with transparent protective tape to protect them. Typically, multiple LED digital tubes are produced in a batch. During the film application process, the multiple LED digital tubes from the same batch are arranged and covered with a single protective film. The film is then cut with a knife to separate the individual LED digital tubes. However, this method can easily scratch the surface of the LED digital tubes, causing damage. Utility Model Content
