Problems solved by technology

[0003] Although the crystal expansion machines currently on the market can achieve a good crystal expansion effect, after the raw material film is stretched, there are many useless parts on the edge, which has an impact on the subsequent process.
Existing crystal expanders are often unable to remove excess raw material film or remove it uncleanly, requiring additional processes to remove excess raw material film, which increases the workload of staff and affects production efficiency

Abstract

The invention discloses an automatic crystal cutting and expanding machine for LED lamps, which comprises a base, a placing platform for placing a raw material film, a crystal expanding part capable of moving up and down, an annular cutting part for cutting the raw material film, and a The film pressing part under the annular cutting part, the first driving part for driving the annular cutting part to move up and down, the second driving part for driving the crystal expanding part to move up and down, and the raw material film for heating The heating assembly; the annular cutting part is provided with an inclined cutting surface, and the bottom of the cutting surface is provided with a cutting knife; the present invention sets the inclined cutting surface so that the cutting knife set at the bottom of the cutting surface can better cut waste The film realizes the purpose of automatically removing the waste film, reduces the process, reduces the workload of the staff, and improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an automatic crystal cutting machine for LED lamps. Background technique [0002] Crystal expansion machine is also called wafer expansion machine or chip expansion machine, which is widely used in the grain expansion process in the production of light-emitting diodes, LEDs, integrated circuits and some special semiconductor devices. After the LED chips are produced from the manufacturer, the LED chips are densely fixed On the raw material film, due to the small gap between the LED chips, this kind of raw material cannot be directly grasped and bonded by the die-bonding machine, so it is necessary to expand the raw material film. Since the raw material film itself is elastic, the crystal expansion will make the raw material Stretching the film can change the distance between the LED chips on the raw film. [0003] Although the current crystal expanders on the marke...
