LED wafer expanding machine with membrane cutting device

Abstract

The invention discloses an LED wafer expanding machine with a membrane cutting device. The machine comprises a base, the base is provided with four support columns, a lower pressing mold board is horizontally arranged on the four support columns, a circular wafer expanding disc is arranged at the center of the lower pressing mold board, and heating tubes are arranged in the wafer expanding disc; one side of the lower pressing mold board is provided with an upper pressing mold board, the lower surface of the upper pressing mold board is provided with a circular groove corresponding to the circular wafer expanding disc, the two sides of the lower pressing mold board are provided with supporting rods, the bottoms of the supporting rods are fixed to the base, the tops of the supporting rods are each vertically provided with a spring, the springs are connected with a gland installing plate, the upper surface of the gland installing plate is provided with an air cylinder, the lower surface of the gland installing plate is provided with a gland, and the lower surface of the gland is provided with an annular blade. According to the LED wafer expanding machine with the membrane cutting device, redundant wafer membranes can be conveniently, quickly and accurately cut off, and meanwhile the condition that operating personnel are injured can be avoided.

Description

technical field [0001] The invention relates to an LED crystal expander, in particular to an LED crystal expander with a film cutting device. Background technique [0002] At present, in the packaging process of LED manufacturers, the LED crystal expander can complete the four processes of heating, stretching, crystal expansion, and film solidification at one time. However, after the film solidification is completed, the excess wafer film must be manually cut off with a blade. Now There is technology and no mechanical equipment to achieve mechanical film cutting. Manual film cutting is not only inefficient, but also due to manual uncertainty, the quality of film cutting is not guaranteed. Operators who manually use blades to cut film may cut their hands. , endangering the personal safety of the operator. To this end, we propose a LED crystal expander with a film cutting device. Contents of the invention [0003] The main purpose of the present invention is to provide an ...
