Description

Printed circuit board (PCB) positions gas stick of tool pore structure

Technical field

This utility model is related to the processing and manufacturing of wiring board, specifically refers to printed circuit board (PCB) positioning gas stick of tool pore structure.

Background technology

With scientific and technological continuous progress, circuit board product surface quality requirements are strict all the more, in order in response to above-mentioned circuit Panel products quality requirements, it is necessary to ensure circuit board surface no scratch in circuit boring, do not damage the conductive layer of circuit surface, Foregoing circuit plate processor, circuit board is positioned on workbench, has drilling tool to the circuit above arrangement and workbench Plate is holed, and because circuit board surface material is softer, and surrounding has and produces the phenomenon tilting, mechanically direct contact electricity Road plate face, is easily caused the vestige of circuit board surface scratch and the conductive coating structure destroying circuit board surface, in turn results in circuit The disappearance that plate is scrapped.

Utility model content

The purpose of this utility model is to provide printed circuit board (PCB) positioning gas stick of tool pore structure, quickly realizes to printed circuit The drilling operating of plate, reduces circuit board damage rate in process.

The purpose of this utility model is achieved through the following technical solutions：

Printed circuit board (PCB) positions gas stick of tool pore structure, including frame and rack-mounted column, turning platform, in institute State frame upper wall and have dovetail groove, turning platform is arranged in dovetail groove by the tab slides that its bottom is arranged, in described steering The orthogonal slide rail with dovetail groove is provided with platform, places plate and be slidably arranged on turning platform by slide rail, in described column Top is provided with cylinder, has stopper slot in the middle part of column, and mechanical arm is set on column, and the outfan activity of described cylinder is passed through Wear column epimere, connecting rod is provided with cylinder outfan, connecting rod is connected with mechanical arm after running through stopper slot, in described limit Position groove upper end and lower end are separately installed with travel switch, and described travel switch is connected with described cylinder, in machine by controller Motor is provided with tool arm, main axis are arranged on the robotic arm, are provided with drill bit in described main shaft one end, and the main shaft other end is pacified Equipped with driven gear, motor output end is provided with driving gear, and described driving gear is connected with driven gear by belt；? It is provided with the blind hole connecting with stopper slot, blind via bottom is provided with the buffer stopper of elastomeric material inside described column, and in institute The circumference stating buffer stopper is provided with cutting line groove of multiple annular.

During use, circuit board to be processed is put in 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, now manually promote connecting rod make circuit board fixture block with spacing Fastened between plate, started cylinder, and then driving mechanical arm is along the axial downward movement of column, that is, drill bit is started circuit board is entered Row boring.Because boring number is more, and position distribution is uneven, and traditional bore process relies primarily on man-hour manually hand-held rig Carry out, and utility model people, by using the penetration capacity of drill bit, multilayer circuit boards half-finished product is superimposed and is placed in placement On plate, after gripping, crept into by drill bit and processed with realizing multiple circuit boards simultaneously, substantially increased boring effect Rate.Further, because the thickness of circuit board is less, even if after multiple circuit boards stack, the displacement of drill bit drilling is still Less it is easy to lead to drill bit in the boring completing circuit board directly with place plate hard contact occur, and then lead to drill bit And place the damage of plate；For this problem, the inside of column is set to hollow by utility model people, and have on column with The stopper slot of connection inside column, the outfan of cylinder axially penetrates through after column along column, the connecting rod on cylinder outfan It is connected with mechanical arm after running through stopper slot, on the upper and lower ends end face of stopper slot, travel switch is installed, that is, cylinder is defeated simultaneously Go out end when driving mechanical arm is realized moving up and down, once the bending part of cylinder outfan is occurred with the extreme position of stopper slot Collision rift, the order that cylinder receives controller just stops stretching, and then avoids drill bit in the excessive movement of vertical direction, to subtract The little damage placing plate and drill bit itself.

Wherein, under column, intrasegmental part has blind hole, and is provided with buffer stopper in blind hole, simultaneously along the circumference of buffer stopper Have cutting line groove of multiple annular, when cylinder outfan moves freely in column, the hypomere meeting of cylinder outfan and column Internal producing is impacted, and then makes cylinder body be subject to serious impact to lead to impaired, and blind hole is as column interior hollow section Extension, its internal diameter is matched with the diameter of cylinder outfan end, that is, in cylinder outfan folding process, cylinder outfan End directly contact with the buffer stopper in blind hole, until connecting rod contacts with the travel switch on stopper slot lower end, led to this Cross the deformation recovery ability of the buffer stopper itself of elastic material, the movement tendency that cylinder outfan end continues to move down can be supported Disappear, the interaction between column and cylinder is reduced with this, that is, avoid mutual impact between cylinder and column it is ensured that cylinder Service life.And, have cutting line groove of multiple annular in the circumference of buffer stopper, ensure that buffer stopper after stress and deformation Quick-return, the impact that the applied stress reducing the internal mutually extruding of buffer stopper and producing causes to buffer stopper, it is to avoid buffer stopper The ability replying deformation is forever lost after deformation.

Have cross-hole in described column epimere, cylinder outfan activity runs through after described cross-hole to downward Stretch, the extension of cylinder outfan is connected through stopper slot with mechanical arm after bending.Section offers section to column thereon For the hole of standard geometrical shapes, i.e. cross-hole, and the local of cylinder outfan is adapted so that column exists with this cross-hole While meeting cylinder outfan and normally move up and down, it is to avoid in boring, mechanical arm produces radially because of applied stress Swing, to improve the borehole accuracy of drill bit.

This utility model compared with prior art, has such advantages as and beneficial effect：

1st, the inside of column is set to hollow by this utility model, and has spacing with connect inside column on column Groove, outfan the axially penetrating through after column along column of cylinder, it is connected with mechanical arm after bending runs through stopper slot again, simultaneously Travel switch is provided with the upper and lower ends end face of stopper slot, that is, cylinder outfan is realized moving up and down in driving mechanical arm When, after the bending part of cylinder outfan is collided with the extreme position of stopper slot, cylinder receives the life of controller Order just stops stretching, and then avoids drill bit in the excessive movement of vertical direction, to reduce the damage placing plate and drill bit itself；

2nd, section offers the hole that section is standard geometrical shapes, i.e. cross-hole, and gas to this utility model column thereon The local of cylinder outfan and this cross-hole are adapted so that column is same meet that cylinder outfan normally moves up and down When, it is to avoid in boring, mechanical arm produces swing radially because of applied stress, to improve the borehole accuracy of drill bit.
