Abstract

The invention discloses a machining apparatus and method for RG long-body LED lamp beads. The machining apparatus comprises a workbench, and the workbench is of an annular structure. Four foot columnsare fixedly arranged on the lower edge of the workbench at equal intervals in the circumferential direction, a mounting plate is fixedly arranged on the lower edge of the workbench through connectingrods, a first air cylinder is fixedly arranged on the mounting plate, a lower die plate is fixedly arranged on a piston rod of the first air cylinder, and the lower die plate is matched with an innerring of the workbench. Beneficial effects are as follows: an infrared distance measuring sensor, a first pressure sensor and a second pressure sensor can be matched with the PLC to perform automaticcontrol, therefore, the stretching distance and the pressing pressure are the same each time, the wafer expanding quality is the same, the wafer film can be automatically fixed, manual fixing is not needed, the mechanization degree is high, and the processing efficiency and the productivity can be improved.

Description

technical field [0001] The invention relates to the field of processing equipment for LED lamp beads, in particular to a processing equipment and method for RG long-body LED lamp beads. Background technique [0002] After the LED chip is diced, it forms an array of grains, and the array of grains is attached to the blue film. The grains on the blue film are arranged very tightly, which is not conducive to the operation of the subsequent process. Therefore, it is usually added in the LED production process. A crystal expansion process processes the array of crystal grains. The crystal expansion process specifically includes: using a crystal expansion machine to expand the blue film with crystal grains attached after slicing, so that the distance between adjacent crystal grains is enlarged. [0003] The existing crystal expansion machine needs to manually control the stretching of the wafer film and the pressing down of the upper template. Manual control is difficult to ensure...
