In this drilling device for processing and producing electronic components, a second electric telescopic rod drives the fixing plate to move to squeeze and fix the electronic components, and no manual fixation of the electronic components is required, which has higher safety. The servo motor drives the drill bit to drill holes in the electronic components, which is simple to operate and easy to use. The debris generated by drilling holes in the electronic components falls into a collection trough for collection, which prevents metal debris of the electronic components from scattering around the device and affecting processing during drilling, and at the same time avoids debris scattering on the workbench and being difficult to clean.
