Automatic multi-head precise drilling machine and drilling technique thereof

Abstract

The invention discloses an automatic multi-head precise drilling machine comprising a rack body. The rack body is internally provided with an alignment platform, a conveying sliding table, a multi-head drilling device and conveying belts. The two ends of the conveying sliding table extend into the alignment platform and the multi-head drilling device correspondingly; the conveying belts are arranged in the multi-head drilling device and located at the front end and the rear end of the conveying sliding table; and the automatic multi-head precise drilling machine further comprises a control boxfor controlling the alignment platform, the conveying sliding table, the multi-head drilling device and the discharging conveying belts to work normally, and a bidirectional observation instrument for observing position adjustment of the multi-head drilling device. The automatic multi-head precise drilling machine has the beneficial effects that firstly, a drill bit and a to-be-machined positioning hole are precisely adjusted and positioned through observation of the bidirectional observation instrument; and the drilling efficiency of the automatic multi-head precise drilling machine is fivetimes or above of that of existing drilling equipment, the automatic multi-head precise drilling machine can completely keep up with the advance speed of an automation line of a single-sided printed circuit board, and an original operation mode of the circuit board can be changed thoroughly.

Description

technical field [0001] The invention relates to PCB board positioning hole processing equipment, in particular to a drilling machine capable of realizing multi-head precise drilling on a circuit board and a drilling process thereof. Background technique [0002] In the prior art, for some small circuit boards in digital electronic products, it is usually set and separated into a plurality of identical small circuit boards on a whole PCB. A whole circuit board is punched into multiple small circuit boards of the same shape. Due to the need for repeated punching during the punching process, it is necessary to position small holes on the edge of each small circuit board diagonally or on the same side Therefore, there will be a plurality of small positioning holes on the entire circuit board, so that the punch can accurately place the circuit board on the positioning pins of the punching die every time it is punched. The existing semi-automatic target drilling machine needs to ...

AI Technical Summary

Problems solved by technology

The existing semi-automatic target drilling machine needs to manually move the target on the circuit board to the working window of the target drilling machine to automatically drill the target. One person can only operate one machine, and the efficiency is low; the existing fully automatic target drilling machine is It has been improved on the basis of the original semi-automatic target drilling machine. Although the whole process can be fully automatic, but there is only one drilling head, the drilling efficiency is still low, and the drilling efficiency of our multi-head drilling equipment is more than 5 times theirs. , can fully keep up with the speed of the single-sided circuit board automatic line, which will completely change the original operation method of the circuit board
