Phenomenon.The device is easy to operate, and detection is accurate, caused by having prevented visually phenomena such as missing inspection, erroneous judgement, while can be disposably
All non-copper facing holes of pcb board are detected, improve detection efficiency.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the installment state decomposition diagram of the utility model；
Fig. 2 is the utility model mounting structure schematic diagram.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Referring to figs. 1 to Fig. 2, a kind of non-copper facing hole detection device of pcb board of the utility model, including pressing plate 2,1 and of bottom plate
Control device.The control device is provided with circuit.2 four jiaos of pressing plate is provided with four location holes 21, and location hole 21 can make pressure
Plate 2 and bottom plate 1 avoid misplacing when matching.Pressing plate 2 is additionally provided with the first metal probe 22 of prominent 2 bottom of pressing plate, described
First metal probe 22 is electrically conductive, and first metal probe 22 is in units of group, and every group of quantity is two, with two of group
First metal probe 22 is not contacted and connected by the circuit inside control device.The bottom plate 1 is arranged on 2 bottom of pressing plate, bottom
Plate 1 is provided with second metal probe 12 on prominent 1 top of bottom plate, and second metal probe 12 is electrically conductive, second gold medal
Belong to probe 12 in units of group, every group of quantity is two, and two the second metal probes 12 with group are not contacted and filled by controlling
Put the circuit connection of inside.The position of first metal probe 22 and the second metal probe 12 and group number need to survey with pcb board
The position in the non-copper facing hole of amount and quantity are corresponding.The non-copper facing holes of PCB that i.e. each needs measures just have two the above
One metal probe 22, just has two the second metal probes 12 below.The control device includes the driving dress that driving pressing plate 2 lifts
Put.The bottom plate surrounding is additionally provided with four positioning columns 11, and positioning column 11 is used for the positioning of pressing plate 2 and pcb board, and positioning column 11 is set
2 steps are equipped with, are disposed with the first cylinder 11a, the second cylinder 11b and the 3rd cylinder 11c, first circle from top to bottom
Column 11a is connected with 21 match activities of location hole of pressing plate 2, and the second cylinder 11b matches connection with the location hole of pcb board, that is, is examining
When survey, pressing plate 2 is positioned against on the step of the first cylinder 11a and the second cylinder 11b, and pcb board is with the 3rd cylinder 11c branch
