Description
Technical field
The present invention relates to the processing and manufacturing of wiring board, specifically refer to creep into structure for multi-layer PCB board.
Background technology
Along with the continuous progress of science and technology, circuit board product surface quality requirements is strict, in order in response to above-mentioned circuit all the more
Panel products quality requirements, it is necessary to ensure that when circuit boring circuit board surface, without scratch, does not damage the conductive layer of circuit surface,
Foregoing circuit plate processor, is positioned over circuit board on workbench, has the drilling tool circuit to disposing and above workbench
Plate is holed, and owing to circuit board surface material is softer, and surrounding has and produces the phenomenon tilted, mechanically direct contact electricity
Plate face, road, is easily caused the vestige of circuit board surface scratch and destroys the conductive coating structure of circuit board surface, in turn resulting in circuit
The disappearance that plate is scrapped.
Summary of the invention
It is an object of the invention to provide and creep into structure for multi-layer PCB board, quickly realize the brill to printed circuit board (PCB)
Hole operation, reduces circuit board damage rate in the course of processing.
The purpose of the present invention is achieved through the following technical solutions:
Structure is crept into, including frame and rack-mounted column, turning platform, in described frame for multi-layer PCB board
Upper wall has dovetail groove, and turning platform is arranged in dovetail groove by the tab slides arranged bottom it, pacifies on described turning platform
Equipped with slide rail orthogonal with dovetail groove, clamping device is slidably arranged on turning platform by slide rail, at described column top
Being provided with cylinder, have stopper slot in the middle part of column, mechanical arm is set on column, and the outfan activity of described cylinder runs through vertical
It is connected with mechanical arm after post and stopper slot, is separately installed with travel switch, described row in described stopper slot upper end and lower end
Cheng Kaiguan is connected with described cylinder by controller, is provided with motor on the robotic arm, and main axis is arranged on the robotic arm,
Described main shaft one end is provided with drill bit, and the main shaft other end is provided with driven gear, and motor output end is provided with driving gear, and institute
State driving gear to be connected with driven gear by belt；Described clamping device includes the U-board being slidably arranged on slide rail, connecting rod
Being connected with fixture block after running through the vertical portion of described U-board, spring housing is located on connecting rod and is placed in U-board vertical portion and fixture block sidewall
Between, it is provided with rectangular aperture at described fixture block away from the bottom surface of the end, one end of spring, and at the horizontal part upper wall of described U-board
It is provided with multiple relief hole.
During use, circuit board to be processed is put into U-board, by mobile turning platform and U-board X to and Y-direction
On position so that circuit board is in suitable processing stations, the most manually promotes connecting rod to make circuit board at fixture block with spacing
Fastened between plate, started cylinder, and then driving mechanical arm is started to enter circuit board along the axial downward movement of column, i.e. drill bit
Row boring.Owing to boring number is more, and position distribution is uneven, and traditional bore process relies primarily on artificial hand-held rig
Carry out, and inventor is by utilizing the penetration capacity of drill bit, is superimposed by multilayer circuit boards half-finished product, utilizes fixture block and U
Multilayer circuit board is fixed by the grasping part between shape plate vertical portion, and then realizes multiple circuit boards and process simultaneously, is greatly improved
Drilling efficiency；Further, owing to the thickness of circuit board is less, even if after multiple circuit boards stack, the position that drill bit creeps into
Shifting amount is the least, it is easy to causes drill bit direct and clamping device generation hard contact in the boring completing circuit board, enters
And cause the damage of drill bit and clamping device；For this problem, the inside of column is set to hollow by inventor, and at column
On have and internal stopper slot connect of column, the outfan of cylinder along column axially penetrate through column after, pass through again through bending
Be connected with mechanical arm after wearing stopper slot, on the end face of two ends up and down of stopper slot, travel switch be installed simultaneously, i.e. cylinder output
Holding when driving mechanical arm realizes moving up and down, once the bending part of cylinder outfan touches with the extreme position of stopper slot
After hitting, cylinder receives the order of controller just to be stopped stretching, and then avoids drill bit to move at the excessive of vertical direction, to reduce
Clamping device and the damage of drill bit self.
And when creeping into, fixture block is provided with the opening of rectangle away from the bottom surface, end, one end of spring, single or multiple
The two ends of circuit board are limited between opening and U-board in the grasping part formed respectively, simultaneously in fixture block sidewall and U-board
Vertical portion between spring is installed, i.e. can guarantee that circuit board place or add man-hour, between circuit board and fixture block, limiting plate
Contact become flexible contact from hard contact, and when the applied stress that circuit board is passed over by the external world, by its two ends
Spring and elastic protrusion respectively applied stress is eliminated, it is achieved the stable processing of circuit board, reduce circuit in boring procedure
There is damage because local action stress concentrates in the corner parts of plate, it is provided that the processing quality of circuit board.Further, at U-shaped
Multiple relief hole is had so that drill bit keeps one section due to inertia reason after running through circuit board on the horizontal part upper surface of plate
Lasting rotation in time is carried out in relief hole, to avoid drill bit directly to contact with U-board and the most impaired, extends drill bit
Service life.
Having cross-hole in described column epimere, cylinder outfan activity runs through after described cross-hole to downward
Stretching, the extension of cylinder outfan is by being connected through stopper slot with mechanical arm after bending.Column section thereon offers cross section
For the hole of standard geometrical shapes, i.e. cross-hole, and the local of cylinder outfan and this cross-hole adapt so that column exists
Meet while cylinder outfan moves up and down normally, it is to avoid when boring, mechanical arm produces radially because of applied stress
Swing, to improve the borehole accuracy of drill bit.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the inside of column is set to hollow by the present invention, and has on column and the stopper slot connected inside column, cylinder
Outfan along column axially penetrate through column after, through bending run through stopper slot again after is connected with mechanical arm, while spacing
Being provided with travel switch on the end face of two ends up and down of groove, i.e. cylinder outfan is when driving mechanical arm realizes moving up and down, once
After the bending part of cylinder outfan and the extreme position of stopper slot collide, cylinder receives the order of controller just to be stopped
Flexible, and then avoid drill bit to move at the excessive of vertical direction, to reduce clamping device and the damage of drill bit self；
2, column of the present invention section thereon offers the hole that cross section is standard geometrical shapes, i.e. cross-hole, and cylinder outfan
Local adapt with this cross-hole so that column is meeting while cylinder outfan moves up and down normally, it is to avoid
During boring, mechanical arm produces swing radially because of applied stress, to improve the borehole accuracy of drill bit.
3, the present invention has multiple relief hole on the horizontal part upper surface of U-board so that drill bit is after running through circuit board
Keep the lasting rotation in a period of time to carry out in relief hole, to avoid drill bit directly to connect with U-board due to inertia reason
Touch and the most impaired, extend drill bit service life.
