Description
Technical field
The utility model relates to a kind of printed circuit board (PCB) instruments of inspection, and the utility model especially relates to a kind of tool bigger than normal and less than normal for inspecting printed circuit board compact dimensions.
Background technology
Along with consumption electronic product is lightening, integration, the development trend of multifunction, its manufacture craft to printed circuit board (PCB) requires more and more higher, also more and more stricter to the dimensional requirement of printed circuit board (PCB), and the printed circuit board (PCB) of batch production, compact dimensions problem bigger than normal and less than normal is easily there is in CNC process, this problem is that personnel's kind of calliper and board are measured in molding manufacture procedure conventional inspection method, but for the circuit board that batch is large, 100% measurement do not accomplished by slide calliper rule and surveying instrument, and drag for the irregular circuit board of groove, slide calliper rule cannot be measured again, the bad plate of size is easily caused to miss client, client has made components and parts when assembling, excessively loose when finding that card does not enter tool or assembles just now, cause well assembling.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of tool bigger than normal and less than normal for inspecting printed circuit board compact dimensions that fast, simply and effectively can check out the bad product of size.
According to the technical scheme that the utility model provides, the described tool bigger than normal and less than normal for inspecting printed circuit board compact dimensions, comprise base plate, be fixed with the first detection pin and second at the upper surface of base plate and detect pin, first detects the axes normal of pin in the plane at base plate place, second detects the axes normal of pin in the plane at base plate place, and the first diameter detecting pin is greater than the diameter of the second detection pin, and the first height detecting pin is greater than the height of the second detection pin.
Described first diameter detecting pin is 1.0 ~ 5.0mm, and the first height detecting pin is 16 ~ 19.8mm.
Described second diameter detecting pin is 1.0 ~ 5.0mm, and the second height detecting pin is 6 ~ 10mm.
Described base plate is square plate, circular flat board or I-shaped flat board.
Tool of the present utility model is utilized to carry out inspecting printed circuit board quality, compared with the existing method of inspection, although increase the step of a upper sleeve-board tool, can fast, simply and effectively check out the printed-wiring board (PWB) that size is bad, improve the production efficiency of later stage assembling.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
This is used for inspecting printed circuit board compact dimensions tool bigger than normal and less than normal, comprise base plate 1, be fixed with the first detection pin 2 and second at the upper surface of base plate 1 and detect pin 3, first detects the axes normal of pin 2 in the plane at base plate 1 place, second detects the axes normal of pin 3 in the plane at base plate 1 place, and the first diameter detecting pin 2 is greater than the diameter of the second detection pin 3, the first height detecting pin 2 is greater than the height of the second detection pin 3.
Described first diameter detecting pin 2 is 1.0 ~ 5.0mm, and the first height detecting pin 2 is 16 ~ 19.8mm.
Described second diameter detecting pin 3 is 1.0 ~ 5.0mm, and the second height detecting pin 3 is 6 ~ 10mm.
Described base plate 1 is square plate, circular flat board or I-shaped flat board.
The utility model is when making, the profile of base plate 1 is selected to determine according to the profile of printed circuit board (PCB), first detection pin 2 and the second installation site detecting pin 3 are determined by the slotted eye position of printed circuit board (PCB), the diameter of the first detection pin 2 is determined by the upper tolerance of the slotted eye of printed circuit board (PCB), namely the upper tolerance of the slotted eye of printed circuit board (PCB) equals the diameter of the first detection pin 2, determined the diameter of the second detection pin 3 by the lower tolerance of the slotted eye of printed circuit board (PCB), namely the lower tolerance of the slotted eye of printed circuit board (PCB) equals the diameter of the second detection pin 3.
Certain 10 layer printed circuit board, printed circuit board (PCB) groove width is 3.0mm, and tolerance is +/-0.1mm, and the concrete steps using tool of the present utility model to carry out detecting are as follows:
(1) coding: provide original copy drawing according to client, to the slotted eye of plank and the position of housing Position Design pin and the external form program editing of tool: at the center place of groove width, if first detects pin 2, diameter is 2.90mm, the same linear position edge detecting pin 2 in distance first arranges the second detection pin 3, diameter is the PIN nail of 3.1mm, and two kinds of PIN must not follow closely tangent; The external form of base plate 1 uses the milling of 2.4mm milling cutter, to facilitate employee's upper and lower plates, derives Composition after OK.
(2) tool processing: select the bakelite plate of 8mm thickness as base plate 1, be fixed on forming machine work top, call in the program that above-mentioned steps one is write; according to the cutter footpath shown in program; choose the drill bit of diameter 2.9mm, 3.1mm and the milling cutter of 2.4mm, the Z value degree of depth is arranged on 15.5mm, starts forming machine; hole at the bakelite plate of 8mm thickness; suspend board, then the Z value degree of depth is arranged on 13.7mm, select 2.4mm milling cutter; start forming machine, pull external form out at the bakelite plate of 8mm thickness.
(3) plant pin: choose with above-mentioned steps two program inside the round end pin of same diameter, wherein the first PIN detecting pin 2 follows closely length and is chosen as 19.8mm, the PIN of the second detection 3 follows closely length and is chosen as 10mm, then uses iron hammer to anti-market in the nail prebored hole of knocking in base plate 1 one by one.
(4) tool dimension inspection: the lamination choosing forming is inserted in tool inspection, during use, first detects pin 2, should be upper and lower smoothly, if can not be upper and lower smoothly, namely judges that this lamination groove width is close to the low limit of tolerance, needs to improve; Check during use plank can not under detect bottom pin 3 to second, pin topmost should be detected second, if plank falls the 3rd when detecting pin location, namely judge that this lamination groove width is bigger than normal, need to improve.
(5) one laminations have detected according to Article 4 method, without exceptionly namely change a lamination inspection, circulate according to this.
