Problems solved by technology

And this may cause that when the user replaces a certain micro-drill, there may be two situations: one is that the wear of the micro-drill has not reached the most serious situation, and it can also be used under the premise of ensuring the drilling quality. Continue to drill, but we replaced it in advance and regrinded it, wasting the life of the drill; The quality of the drilled holes cannot meet the required standards, which is also a waste

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0040] Due to the friction between the micro-drill and the material of the PCB board during the drilling process, the material of the drill bit is consumed to a certain extent, causing wear and tear, which makes the cutting of the bit dull; and the blunt micro-drill makes the friction more intense, and the friction is more intense , the easier it is to aggravate the wear, the more heat is generated, and the higher the temperature is, the wear of the drill bit is closely related to the temperature of the drill bit. Therefore, we can detect the wear of the micro drill bit at this time by capturing the temperature of the micro drill bit state.

[0041] The method for detecting the degree of wear of the micro-drill of the present invention, such as figure 1 and figure 2 shown, including the following steps:

[0042] A: Detect the temperature o...

Abstract

The invention discloses a method for detecting the wear degree of a microbit, a device and a drilling machine which use the method. The method for detecting the wear degree of the microbit comprises the following steps: A: the temperature of the microbit is detected; and B: the temperature which is detected in the step A is compared with preset wear critical temperature, if the temperature is higher than or equal to the preset wear critical temperature, the wear degree of the microbit is determined to be serious; and if the temperature is lower than the preset wear critical temperature, the wear degree of the microbit is determined to be within the normal range. The wear degree of the microbit is detected by detecting the temperature of the microbit, therefore, the wear degree of the microbit can be known without demounting the bit, and the detection is very convenient.

Description

technical field [0001] The invention relates to the field of manufacturing printed circuit boards, and more specifically, relates to a method for detecting the wear degree of a micro-drill, and a device and a drilling machine using the method. Background technique [0002] We usually use micro-drills to drill holes in printed circuit boards for further processing. [0003] When the micro-drill drills the PCB board, as the number of drilled holes gradually increases, the wear of the micro-drill will gradually increase. When the wear of the micro-drill reaches a certain level, the micro-drill cannot complete the drilling work well, which in turn will further accelerate the wear of the drill, and the quality of the drilled hole will also decline. At this time, the micro-drill It needs to be replaced with a new drill bit or removed for regrinding. [0004] At this stage, there is no good way to estimate the degree of wear of the micro-drill during processing, and when and to w...
