Abstract
A kind of method of bevelling machine and its processing PCB plate, the present invention provides a kind of method using the conventional bevel edge process equipment processing small inside groove photoelectricity pcb board of 1mm or more, solves the technical issues of conventional bevelling machine cannot carry out the processing of shape bevel edge to the small inside groove product of 1~6mm.
Description
Technical field
The present invention relates to PCB manufacturing fields, and in particular to a kind of method of pcb board bevel edge processing.
Background technique
Intelligent opto-electrical equipment is more and more to be connected using highly integrated modularization Installation Modes more by finger plug
Be conducive to repair and maintain.For convenience of plug, bevel edge working process is carried out to plug position in shape process when PCB makes.
It is in raised type between finger position and shape figure when golden finger position designs since the diameter of conventional bevel edge knife is 6mm, it is oblique when needing
When the golden finger and shape figure of side processing are in same straight line, routinely need the sipes of reserved 6mm or more to guarantee that bevel edge adds
Working hour bevel edge side will not injure shape figure.Come higher as the density of printed board surpasses, integrated modular volume is smaller and smaller, is
More installation spaces are reserved, more and more PCB plugs use concave Installation Modes.And conventional bevel edge process equipment by
Limit in technology, the groove of 6 mm or more or the finger plug product of raised type design class can only be machined with, for interior groove width
Degree, which is less than 6mm product below, can not then process.
Because cannot directly produce inside groove product using bevelling machine, part producing manufacturer is oblique using gong machine cooperation special angle
Side knife is come out the bevel edge angular milling of golden finger using the scheme of controlled depth milling, but there are each golden finger positions to need for the technical solution
Positive and negative milling 2 times (production efficiency is low), forming machine movement speed slow (speed there was only bevelling machine 30%) and need positioning, upper and lower plates
Etc. technical problems, be not suitable for batch production.The present invention provides a kind of conventional bevel edge process equipment processing small inside groove of 1mm or more of utilization
The method of photoelectricity pcb board, the technology of shape bevel edge processing cannot be carried out to the small inside groove product of 1~6mm by solving conventional bevelling machine
Problem.
Summary of the invention
The present invention is with the small inside groove of the rapid automatized production technology processing 1mm or more of conventional chamfering equipment or raised type photoelectricity
The method of the shape bevel edge processing of pcb board finger plug, the conventional bevelling machine of solution, which can only produce the outer frid of 6mm or more, to give birth to
The production efficiency of the technical issues of producing 1~6mm inside groove product, the processing of fast lifting bevel edge meets the need of enterprise's large-scale production
It wants.
There are two types of existing bevelling machine working methods: 1. bevel edge knives are fixed, the mobile crawler type of pcb board of processing；2. tiltedly
Side knife is mobile, the fixed bevel edge of pcb board of processing.Crawler type bevelling machine is since bevel edge knife has been fixed, the PCB processed
Plate passes through the product that crawler belt transmission can only be that raised type takes the air line.
It is oblique to specified position progress that the present invention provides a kind of fixed bevel edge knife of plank accurate movement under the driving of program
The bevelling machine of side processing, is equipped with an inside groove bevel edge knife, it is characterised in that: bevel edge knife is column type, including interconnecting piece and processing department, is connected
The diameter of socket part is greater than the diameter of processing department, and the diameter of interconnecting piece is no more than 2mm, and interconnecting piece is removably connected with fixed sleeve part,
The end of processing department is provided with 4 cutters tooth, cutter tooth fan-shaped distribution centered on axle center, is in 90 degree of symmetrical, knives between cutter tooth
The gap of between cog constitutes notch, and also spiral is provided with chip space in processing department, and chip space is communicated with notch.Fixed sleeve part is column
Structure, middle part are provided through hole, and the interconnecting piece of bevel edge knife, which can cooperate, to insert in the hole, the junction of fixed sleeve part and interconnecting piece
Stress can inwardly reduced bore until bevel edge knife is fixed.Bevelling machine uses pneumatic type fixed clamping device, passes through fixed sleeve part
It is detachably connected to bevel edge knife.
Further, bevel edge knife uses diameter for 2mm, and wolfram steel column time processing of the length not less than 22mm shapes.
Further, bevel edge knife edge coating has diamond or titanium.
Further, fixed sleeve part is made of steel material, and total length is 20~30mm.
Using bevelling machine processing PCB plate provided by the invention, when bevel edge machining inside groove width is the pcb board of 1~6mm
Cutting when speed processes pcb board of the interior groove width greater than 6mm compared to it with speed of returning sword reduces by 50%.
Conventional bevelling machine has the function of automation cutting and sequencing movement, bevel edge of the present invention to conventional chamfering equipment
Knife and processing method improve, and existing bevel edge machine equipment is allowed to have the function of conventional machining raised type linearity plug product
Can, and have the function of the small inside groove finger plug product of 1~6mm of accurate cutting.
Detailed description of the invention
The invention will be further described for attached drawing, but the embodiments in the accompanying drawings do not constitute any limitation to the present invention.
Fig. 1 is the bevel edge knife structural schematic diagram that one embodiment of the invention provides.
Fig. 2 is the bevel edge knife front view that one embodiment of the invention provides.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
As shown in figs. 1-2, bevel edge knife made of a kind of wolfram steel that one embodiment of the invention provides, bevel edge knife are column type,
Including interconnecting piece 12 and processing department 11, the diameter of interconnecting piece 12 is greater than the diameter of processing department 11, and the diameter of interconnecting piece 12 is 2mm,
Interconnecting piece 12 is removably connected with fixed sleeve part, and the end of processing department 11 is provided with 4 cutters tooth 112, during cutter tooth 112 with axle center is
The fan-shaped distribution of the heart, symmetrical in 90 degree between cutter tooth 112, the gap between cutter tooth 112 constitutes notch, and spiral in processing department 11
It is provided with chip space 111, chip space 111 is communicated with notch, and 111 quantity of chip space is identical as 112 quantity of cutter tooth.
Fixed sleeve part is column structure, and the fixed sleeve part that columnar objects can be fixed present in any prior art can be used
Lantern ring is such as clamped, middle part is provided through hole, and the interconnecting piece 12 of bevel edge knife, which can cooperate, to insert in the hole, fixed sleeve part and interconnecting piece
12 junction stress can inwardly reduced bore until bevel edge knife is fixed.
