Problems solved by technology

[0002] The normal drilling machine senses whether the drill is broken through the discharge of powder chips during the drilling process, while the slotted hole is drilled multiple times by the drill to form a long strip of slotted holes, so it will not There has always been enough dust to be sensed. Therefore, the drilling rig manufacturer will set that during the drilling process, when the equipment reads the G85 command (drilling command), the dust sensing device will be turned off by default, and this will cause the trough Hole drilling broken knife can not be alarmed in time, resulting in quality hidden dangers of missed drilling

Embodiment Construction

[0006] The present invention is further described below.

[0007] The invention discloses an alarm monitoring method for drilling slot knife breakage, which is different from the prior art in that it includes one or more numerically controlled drilling rigs, and also includes a monitoring host. The sensing device forms a signal data transmission connection between the monitoring host and the sensing device. When all CNC drilling rigs replace the groove cutter, the sensing device will measure the length of the groove cutter, and the sensing device will transmit the measurement data to the monitoring host. After comparing the measured parameters, it is judged whether the groove cutter is broken or not.

[0008] In specific implementation, a row of air ducts can be provided on one side of the sensing device for blowing ion wind laterally, so as to avoid fine dust particles from adhering to the surface of the sensing device and affecting the correctness of the detection data.

Abstract

The invention discloses a monitoring method for a broken drilling slot cutter alarm, which comprises one or more numerical control drilling machines, and a monitoring main unit. The numerical controldrilling machine is provided with an induction device for detecting the length of a slot cutter, and a signal data transmission connection is formed between the monitoring main unit and the inductiondevice. When all the numerical control drilling machines withdraw and replace the slot cutters, the induction devices measure the lengths of the slot cutters, and the induction devices transmit the measurement data to the monitoring main unit. The monitoring main unit determines whether the slot cutters are broken after comparing the measured parameters. The invention adopts the monitoring main unit to realize the monitoring of the length of the slot cutter in one or more numerical control drilling machines, and finally judges whether the slot cutter is broken. The monitoring method has a lowfalse alarm rate and can give a timely broken cutter alarm, which effectively improves the processing quality.

Description

technical field [0001] The invention relates to the technical field of PCB board drilling equipment, in particular to a method for alarming and monitoring the breakage of a drilling groove cutter. Background technique [0002] The normal drilling machine senses whether the drill is broken through the discharge of powder chips during the drilling process, while the slotted hole is drilled multiple times by the drill to form a long strip of slotted holes, so it will not There has always been enough dust to be sensed. Therefore, the drilling rig manufacturer will set that during the drilling process, when the equipment reads the G85 command (drilling command), the dust sensing device will be turned off by default, and this will cause the trough The tool cannot be alarmed in time when the hole is broken, which leads to the quality hidden danger of missed drilling. Contents of the invention [0003] The object of the present invention is to provide an alarm monitoring method f...
