Problems solved by technology

However, for the drilling process of metal plates, the drilling process in the industry generally adopts a single metal plate drilling operation, the processing efficiency is slow, the manufacturing cost and energy consumption are high.
[0003] Especially when many metal plates have the same hole positions, the efficiency of drilling a single metal plate is low
[0004] Further, with the rapid development of LED products, conventional substrates such as FR4 and CAM-3 are poor conductors of heat, with interlayer insulation and slow heat dissipation, while the high heat dissipation of metal substrates leads to rapid development. Therefore, It is necessary to improve the drilling technology of metal plates

Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly co...

Abstract

The invention relates to an overlapping-drilling method. The overlapping-drilling method includes: overlapping at least two layers of metal plates to be drilled; according to thickness of the metal plates in layer, setting a sequential process of a drill bit, of a drilling jig, relative to the metal plates; according to the sequential process, drilling the metal plates in an overlapping manner. With the above method that at least two layers of the metal plates are drilled in the overlapping manner according to the sequential process, multiple metal plates can be overlapped and drilled at one step, machining efficiency of the metal plates is greatly improved, manufacturing cost of products is lowered, and energy consumption is further lowered; further, due to the adoption of the multi-drilling method, drilling resistance of the drill bit drilling down is buffered and reduced, overload machining borne by a spindle is efficiently alleviated, and operation efficiency is improved by about 40%-70%.

Description

technical field [0001] The invention relates to drilling technology, in particular to a stacked drilling method. Background technique [0002] With the development of science and technology, drilling technology is changing with each passing day. However, for the drilling process of metal plates, the drilling process in the industry generally adopts a single metal plate drilling operation, which leads to slow processing efficiency, high manufacturing cost and high energy consumption. [0003] Especially when the hole positions of many metal plates are the same, the efficiency of drilling a piece of metal plate alone is relatively low. [0004] Further, with the rapid development of LED products, conventional substrates such as FR4 and CAM-3 are poor conductors of heat, with interlayer insulation and slow heat dissipation, while the high heat dissipation of metal substrates leads to rapid development. Therefore, There is a need to improve drilling techniques for sheet metal....
