Abstract

The invention relates to a robot arm structure, in particular to a dual robot arm device which is used in a grain sorting machine or a die bonder, can simultaneously drive two sets of vacuum suction nozzle devices to carry out grain taking and placing actions and conveniently adjust the down force to the grain, and is provided with a down force sensor. The robot arm comprises a rear arm (401), a supporting plate (407), an insulating ring (406), a rear arm electrode bolt (402), an electrode bolt nut (405), a flexible sheet (409), a front arm (411), a front arm electrode (415), a pressure adjusting rod (403), a pressure adjusting nut (404), a spring (410), a vacuum suction nozzle (412) and a vacuum suction nozzle joint (413), wherein the front end of one end of the rear arm (401) is fixed with the flexible sheet (409); the front end of the flexible sheet (409) is fixed with the front arm (411); and the front end of the front arm (411) is provided with a vacuum suction nozzle fast-disassembly structure. The robot arm has the advantages of simple structure, convenient adjustment, smooth movement, and great improvement of efficiency, which meets economic benefits, and has industrial production valve.

Description

technical field

[0001] The invention relates to a mechanical arm mechanism, especially a device used in a grain sorting machine or a solid crystal machine, which can simultaneously drive two sets of vacuum suction nozzle devices to carry out grain pick-and-place actions, and can conveniently adjust the loading and unloading of the grains. pressure, and a dual-arm setup with a downforce sensor. Background technique

[0002] In the production process of light-emitting diode crystal grains, the whole wafer is produced first, and the wafer is divided into independent crystal grains that are completely separated from each other after dicing, and are independently adhered to the sticky blue film. In the subsequent wafer sorting process, the die sorter needs to use a vacuum nozzle device to pick up the die from the blue film and place it in the specified position; or in the subsequent die bonding process, the die bonding machine needs to use a The vacuum nozzle device picks up the...
