Abstract
The utility model discloses a PCB (Printed Circuit Board) positioning tool including a workbench comprising a bottom board (1). The bottom board (1) is provided with a left guide post (4), a right guide post (9), a left vertical board (6) and a right vertical board (8). The left vertical board (6) and the right vertical board (8) are fastened together with a screw and a hinge base (7). The hinge base (7) is connected with a press rod (5) through a rotary pin. The press rod (5) is connected with a downwardly-pressing guide shaft (3) whose tail end is provided with a testing probe. The press board (2) is provided with three positioning holes of the same size. The press board (2) is arranged between the left guide rod (4) and the right guide rod (9) through positioning holes in the left side and in the right side. The diameter of the downward-pressing guide shaft (3) is greater than that of each positioning hole of the press board (2). By adopting the PCB positioning tool, an aim of positioning and welding testing probes accurately in an errorless manner can be achieved.
Description
Technical field
The utility model relates to a kind of printed circuit board (PCB) localization tool.
Background technology
Prior art adopts artificial welding, has the defects such as efficiency is low, fraction defective is high; Test probe requires be welded into the vertical angle of 90 degree and remain on sustained height, and artificial welding just needs by rule of thumb and range estimation, occurs unavoidably deviation.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of printed circuit board (PCB) localization tool, to reach accurate positioning welding test probe, avoids the object of error.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of printed circuit board (PCB) localization tool, comprise the work top that base plate 1 forms, described base plate 1 is respectively equipped with left guide pillar 4, right guide pillar 9, left riser 6 and right riser 8, described left riser 6 and described right riser 8 are by screw and twisted seat 7 lockings, described twisted seat 7 is connected with depression bar 5 by shipping and reselling on another market, described depression bar 5 is fixed with and presses down guide shaft 3, described in press down guide shaft 3 ends and be provided with test probe; On pressing plate 2, offer three onesize location holes, described pressing plate 2 is applied between described left guide pillar 4 and described right guide pillar 9 by the location hole of the left and right sides, described in press down guide shaft 3 diameter be greater than the diameter of described pressing plate 2 location holes.
Pass through technique scheme, a kind of printed circuit board (PCB) localization tool that the utility model provides, printed circuit board (PCB) (being generally tablet or minitype circuit board) is placed on base plate, guide pillar by two protrusions of base plate positions, the test probe that presses down guide shaft inserts in pressing plate (patrix) location hole, rotate and lower moulded rod, test probe can navigate on printed circuit board (PCB), thereby welds.The utility model can effectively avoid artificial welding directly range estimation cause cannot accurately locate the defect that causes welding error.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1, Fig. 2, the utility model provides a kind of printed circuit board (PCB) localization tool, comprise the work top that base plate 1 forms, base plate 1 is respectively equipped with left guide pillar 4, right guide pillar 9, left riser 6 and right riser 8, left riser 6 and right riser 8 are by screw and twisted seat 7 lockings, twisted seat 7 is hinged with depression bar 5 by shipping and reselling on another market, and depression bar 5 is fixed with and presses down guide shaft 3, presses down guide shaft 3 ends and is provided with test probe; On pressing plate 2, offer three onesize location holes, pressing plate 2 is applied between left guide pillar 4 and right guide pillar 9 by the location hole of the left and right sides, the diameter that presses down guide shaft 3 is greater than the diameter of pressing plate 2 location holes, so that test probe can penetrate pressing plate 2, and press down guide shaft 3, play the effect pressing down with dynamic pressure plate 2.
Pass through technique scheme, a kind of printed circuit board (PCB) localization tool that the utility model provides, printed circuit board (PCB) (being generally tablet or minitype circuit board) is placed on base plate 1, by positioning of the protrusion on base plate 1, the test probe that presses down guide shaft 3 inserts in pressing plate 2 (patrix) location hole, machining benchmark when location hole is made for printed circuit board, rotate and lower moulded rod 5, test probe can navigate on printed circuit board (PCB), test probe is for connecting the conductor of printed circuit board (PCB) and external test facility signal, thereby welds.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
