Description

Quickly check PCB shape groove width jig

Technical field

The utility model relates to a kind of PCB production equipments, and in particular to a kind of quickly to check PCB shape groove width jig.

Background technique

Groove width measurement when for PCB sharp processing is generally measured using vernier caliper or Quadratic Finite Element and three-D, mesh After preceding sharp processing, all grooved holes of plate face 95% are designed, and 60% slot is there are radian (arc groove), these positions can not be used Vernier caliper or Quadratic Finite Element measurement or measurement are difficult, original measurement method Shortcomings, and measurement efficiency is low:

In addition, being operated more when being measured using existing measuring device；Integrated operation process uses following steps: Manufacturing Worker with a location point in vernier caliper measurement slot==" read data validation OK==" measure same slot again Another side correspond to test point==" read data validation OK==" vernier caliper be unable to measure slot position width==" send plate (in three-D room)==" three-D measurement (put, take)==" read data==" subregion put plate==" Manufacturing Worker is from three Plate is fetched in dimension room, and entire operation process is tediously long, and measurement efficiency is low (1 piece/minute) because using traditional detection jig without Method meets production requirement.

Utility model content

Based on this, it is necessary to aiming at the shortcomings in the prior art, provide a kind of quickly inspection PCB shape groove width jig.

The utility model is achieved in the following ways: a kind of quickly to check PCB shape groove width jig, including measurement Disk, the indicator board for being fixed on Measuring plate two sides, if Measuring plate is equipped with dry measure item, the middle part for measuring the spaced winding Measuring plate of item is in Increased radioactivity, and the end position of item is measured from outside is reached between two Measuring plates, the indicator board is backwards to measurement plate Lateral surface be equipped with several index lines, and the index line on indicator board is aligned one by one with the measurement item in Measuring plate；The survey The measurement item setting cylindrical on disk is measured, and the measurement item in the Measuring plate is divided into several groups, the measurement on different groups The outer diameter of item is of different sizes, is equipped with numeral mark, number mark on every index line or index line side in the Measuring plate Note is for marking the corresponding measurement item of index line.

Further, fixing seat is equipped in the middle part of the Measuring plate, fixing seat is equipped with several jacks, and in fixing seat Jack is circumferentially distributed, and the both ends of the measurement item are respectively test lead and fixing end, and the test lead reaches two Measuring plates Outside, the fixing end is coupled by the way of screw thread or interference fit with jack.

Further, the end position far from fixing seat is equipped with graduation mark on the measurement item.

The utility model quickly checks that the beneficial effect of PCB shape groove width jig is: different by being arranged in Measuring plate The measurement item of model, while indicating using indicator board the sizes of different measurement items, when measurement, directly adopt measurement item and quilt The functional hole for surveying PCB carries out interspersed cooperation, and whether measurement functional hole meets the requirements, and whole measurement process is convenient, fast, effectively mentions High detection efficiency saves artificial detection cost, practical, has stronger dissemination.

Detailed description of the invention

Fig. 1 is the structural schematic diagram that the utility model quickly checks PCB shape groove width jig.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.

As shown in Figure 1, the utility model provides a kind of quickly inspection PCB shape groove width jig, the function on pcb board Hole inside diameter measurement, the functional hole can be through-hole, blind hole, location hole etc., and the quick inspection PCB shape groove width jig includes surveying Amount disk 10, the indicator board 20 for being fixed on 10 two sides of Measuring plate measure the spaced winding of item 11 if Measuring plate 10 is equipped with dry measure item 11 The middle part of Measuring plate 10 is in increased radioactivity, also, measures the end position of item 11 on the outside of reaching between two Measuring plates 10.

The indicator board 20 is equipped with several index lines 21, and the index line on indicator board 20 backwards to the lateral surface of measurement plate 21 are aligned one by one with the measurement item 11 in Measuring plate 10.The setting cylindrical of measurement item 11 in the Measuring plate 10, and institute It states the measurement item 11 in Measuring plate 10 and is divided into several groups, the outer diameter of the measurement item 11 on different groups is of different sizes.In this practical example, The quantity of every group of measurement item 11 only has one, is equipped with and counts on every index line 21 or 21 side of index line in the Measuring plate 10 Word mark 22, the numeral mark 22 is for marking the corresponding measurement item 11 of index line 21.

Fixing seat is equipped in the middle part of the Measuring plate 10, fixing seat is equipped with several jacks, and the jack in fixing seat is in The both ends of circle distribution, the measurement item 11 are respectively test lead and fixing end, and the test lead reaches two Measuring plates 10 Outside, the fixing end are coupled by the way of screw thread or interference fit with jack.

More preferably, the end position far from fixing seat is equipped with graduation mark (not shown) on each measurement item 11, is used for The hole depth of functional hole is measured, the flexibility quickly checked when PCB shape groove width jig uses is improved.

When measurement, the size requirement of slot in corresponding PCB drawing, maximum upper limit and minimum lower limit ruler when determining measurement are checked The measurement item 11 of very little size, and plate to be tested is placed in workbench, function is vertically put into groove width test upper limit pin Kong Zhong is changed into after lower limit pin is vertically put into slot, uniform translation test-strips, if measurement item 11 passes through slot if blocking Hole, then this board slot hole width is of the required size, into next piece of plate measurement of lower measurement, conversely, the PCB is substandard product.

The utility model quickly checks that the beneficial effect of PCB shape groove width jig is: by being arranged not in Measuring plate 10 It with the measurement item 11 of model, while indicating using indicator board 20 sizes of different measurement items 11, when measurement, directlys adopt survey Amount item 11 and the functional hole of tested PCB carry out interspersed cooperation, and whether measurement functional hole meets the requirements, whole measurement process is convenient, Fast, detection efficiency is effectively improved, artificial detection cost is saved, it is practical, there is stronger dissemination.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
