Description
Technical field
The utility model relates to the field tests of circuit board, in particular to a kind of automatic positioning equipment of circuit board testing needle-bar.
Background technology
At present, in the test of railway signal system signal circuit board, mainly pass through the location of manual operation completing circuit plate and test probe, this method automaticity is not high yet, and make survey crew produce erroneous judgement than being easier to, cause measuring result error larger; In addition, manual operation is more time-consuming, and the efficiency causing circuit board to be measured is low.
Summary of the invention
In order to solve the above-mentioned technological deficiency existed in prior art, the utility model provides a kind of automatic positioning equipment of circuit board testing needle-bar, is intended to the accuracy improving probe positioning, improves the testing efficiency of circuit board.
To achieve these goals, the technical solution of the utility model is: a kind of automatic positioning equipment of circuit board testing needle-bar, comprising: needle-bar drive motor (1), screw rod (2), upper backup pad (3), needle-bar plate (4), probe (5), guide rod (6), board under test groove (7), locking device (8), micromatic setting (9), base (10).
It is characterized in that: screw rod (2) is connected with upper backup pad (3); Needle-bar plate (4) is fixed on upper backup pad (3), and it is mobile that needle-bar drive motor (1) controls needle-bar plate (4) by screw rod (2); After board under test is placed in board under test groove (7), regulate board under test position by micromatic setting (9), enable probe (5) and the test point precise positioning on board under test; The board under test of having good positioning is fixed in board under test groove (7) by locking device (8), prevents board under test in test process from offseting, causes test result to occur error.
Further, the utility model needle-bar plate (4) is moved in the vertical direction by guide rod (6).
Further, the utility model micromatic setting (9) is positioned at the inside and outside both sides of board under test groove (7), can be regulated the relative position of board under test and probe (5) by micromatic setting.
The utility model has following advantage.
1 can realize circuit board under test and test the automatic location of needle-bar, improves the precision of circuit board testing.
2 the utility model simplify manually-operated process, greatly enhance the efficiency of circuit board testing.
Accompanying drawing explanation
Fig. 1 is the structural representation of circuit board testing needle-bar.
Reference numeral: needle-bar drive motor (1), screw rod (2), upper backup pad (3), needle-bar plate (4), probe (5), guide rod (6), board under test groove (7), locking device (8), micromatic setting (9), base (10).
Embodiment
Be further described below in conjunction with the embodiment of Figure of description to the automatic positioning equipment of a kind of circuit board testing needle-bar of the utility model; Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model example, an automatic positioning equipment for circuit board testing needle-bar, comprising: needle-bar drive motor (1), screw rod (2), upper backup pad (3), needle-bar plate (4), probe (5), guide rod (6), board under test groove (7), locking device (8), micromatic setting (9), base (10).It is characterized in that: screw rod (2) is connected with upper backup pad (3); Needle-bar plate (4) is fixed on upper backup pad (3), and it is mobile that needle-bar drive motor (1) controls needle-bar plate (4) by screw rod (2); After board under test is placed in board under test groove (7), regulate board under test position by micromatic setting (9), enable probe (5) and the test point precise positioning on board under test; The board under test of having good positioning is fixed in board under test groove (7) by locking device (8), prevents board under test in test process from offseting, causes test result to occur error.
Principle of work of the present utility model is: circuit board under test is put into board under test groove (7), regulates micromatic setting (9), probe (5) can be contacted with the tested point on circuit board under test accurately.Start needle-bar drive motor (1), upper backup pad (3) and needle-bar plate (4) are moved down along guide rod (6), when the probe (5) on needle-bar plate (4) arrives above board under test, needle-bar drive motor (1) stops, regulate micromatic setting (9), probe (5) accurately can be aimed at the tested point on circuit board under test; Now, fixed by micromatic setting (9), drive motor (1) starts makes upper backup pad (3) and needle-bar plate (4) be moved upwards up to reference position; Just need not regulate micromatic setting (9) again when testing later circuit board, after directly circuit board under test being put into board under test groove (7), with locking device (8), circuit board under test be fixed, start needle-bar drive motor (1) and just can start to test.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model; Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
