Description

Technical Field

[0001] The present invention relates to the technical field of heat sink processing, and particularly relates to a drilling device for heat sink processing. Background Art

[0002] A heat sink is a device used to dissipate heat from heat-generating electronic components, and it has various shapes, such as sheet-shaped, multi-sheet-shaped (such as shovel-tooth heat sinks), etc. During the production process of heat sinks, a drilling device is generally required to perform drilling operations on the heat sinks.

[0003] For example, Chinese invention patent CN117620254A discloses a drilling machine for an insert-type heat sink with a positioning function, including a workbench and a drilling device, which can complete the positioning and fixing of the heat sink and drilling.

[0004] However, it still has the following problems. First, during the drilling process, a structurally complex positioning component and a positioning process are required to accurately position the heat sink: turn on the power module, and supply power to four groups of electric push rods at the same time, so that the four groups of electric push rods push forward at the same time, respectively driving the clamping plates at their own ends to slide relatively, and clamping and positioning the heat sink on the placement pad. Since the four groups of electric push rods slide at the same time, regardless of the size of the heat sink, the position of the heat sink is always in the centered position. Second, for the multi-sheet heat sink structure, it is difficult to realize the directional automatic feeding process of the heat sink. In addition, after the heat sink completes operations such as punching, a complex reverse control process is required to disassemble and unload the heat sink. With the development of high-efficiency and automated production technologies, the above-mentioned device has gradually become difficult to meet the industry development trend.
