Description
Technical field
The utility model relates to traffic control proving installation, specifically a kind of automatic test needle-bar of circuit board.
Background technology
Existing automatic test needle-bar, generally automatically can not detect preferably, and there is probe unbalance stress, does not have the problems such as protection and the protection of locking function or fixed head assembly and locking property be poor.One can realize locking, protection, location and self-aligning automatic test needle-bar, can solve the problem preferably and difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of automatic test needle-bar of circuit board, its can overcome above-mentioned defect and take up room little, reliability is high, easy to operate, can automatically detect.During use, upper stitch bed assembly makes foldable sport from side, drives linkage board to move downward.After upper needle plate probe and circuit board contacts, slip linkage board and drive plate assemblies, make it to day plate and the downward pressure of upper needle plate assembly one, probe contacted completely with circuit board, improves the reliability of detection.Another free-revving engine of the present utility model is to provide a kind of automatic detection device, can carry out auto-alignment and by probe automatic data collection.
In order to solve prior art Problems existing, the technical solution adopted in the utility model is.
The automatic test needle-bar of above-mentioned a kind of circuit board, wherein tests needle bed component and comprises: upper stitch bed assembly, linkage board and actuator, fixed head assembly, base assembly; Described upper stitch bed assembly can be one or more; Described linkage board is connected with described base assembly; Described actuator is connected with described linkage board; Described fixed head assembly is identical with described upper stitch bed number of components.
The course of work of this needle-bar frock is: first settle appropriate by needle-bar frock, be placed on by circuit board in the Baltimore groove of support plate center, support plate is positioned at a drawer that can move forward and backward.Afterwards, can be switched on power.After switching on power, the assembly of sky plate and upper needle plate makes upset foldable sport from side, slowly transfer, be depressed into and make probe substantially touch circuit board test point; At this moment, the link gear being positioned at needle-bar both sides starts effect, and link gear upper end is slided into a day plate middle position; (containing a rubber stopper, this is movable end, can move left and right in link gear upper end; Link gear lower end is fixed on pedestal, this is stiff end, be connected with pedestal) pull link gear bearing handle, it is made to move as " signature well ", utilize lever principle, link gear upper end is slowly pressed down, to sky plate and upper needle plate one pressure, thus guarantees that all probes all can contact with circuit board completely; After detection completes, by link gear upper end to sliding on one side, until leave a day plate region; Cut off the electricity supply, drive vertical columns upwards to start sky plate and needle plate, make it slowly leave circuit board, after leaving location-appropriate, drawer can be extracted out and take out circuit board, prepare the detection of next circuit board.Be provided with connecting groove between the pedestal of this frock and sky plate, be used for switching on power; Bottom needle plate, be also provided with reference column, reference column is positioned at the surrounding of needle plate, and needle plate can be made like this when being depressed into support plate position, and vertical columns by being pressed on the surface of circuit board, thus ensure that circuit board steadily and do not depart from or tilt; This device can the whether short circuit of testing circuit plate, open circuit, filter out bad circuit board.
Accompanying drawing explanation
fig. 1 is the automatic test needle-bar schematic diagram of a kind of circuit board of the present invention.
In figure: 1-sky plate, 2-needle plate, 3-reference column, 4-probe, 5-drawer, 6-circuit board, 7-support plate, 8-pedestal, 9-bearing.
Needle-bar both sides be link gear assembly, its upper end is containing a rubber stopper, and this end is movable end, can move left and right.Link gear lower end is fixed on pedestal, and this is stiff end, is connected with pedestal.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated; Fig. 1 is the automatic test needle-bar schematic diagram of a kind of circuit board of the present invention; Described upper stitch bed assembly is made up of sky plate 1, needle plate 2, probe 4; Described linkage board and actuator are made up of sky plate 1, bearing 9; Described fixed head assembly is made up of sky plate 1, reference column 3; Described base assembly is made up of drawer 5, pedestal 8.
Specific embodiment described herein, in order to explain the utility model, is not limited to the utility model; Be described below in conjunction with the embodiment of Figure of description to the needle-bar frock for testing circuit plate of the present utility model; As shown in Figure 1, according to the needle-bar frock for testing circuit plate of the present utility model, comprise fixed head assembly, upper stitch bed assembly, linkage board and actuator, base assembly, described actuator is connected with described linkage board, and described linkage board is connected with described base assembly.
The specific works of this needle-bar device is described as follows: first circuit board is placed in the Baltimore groove of support plate center, then switches on power through the connecting groove between pedestal and upper needle plate.When the rear faller that switches on power starts to make upset foldable sport from side, slowly transfer, until when the tip of probe contacts substantially with the test point on circuit board, upper needle plate and sky plate stop moving downward, the link gear being positioned at needle-bar both sides starts effect, (containing a rubber stopper, this is movable end, can move left and right in link gear upper end; Link gear lower end is fixed on pedestal, and this is stiff end, is connected with pedestal.) link gear upper end is slided into a day plate middle position, pull bearing handle, make it move as " signature well ", link gear upper end slowly presses down, to sky plate and upper needle plate one pressure, thus guarantee that all probes all can contact with circuit board completely, achieve locking function and defencive function; After detection completes, by link gear upper end to sliding on one side, until leave a day plate region.Cut off the electricity supply, drive vertical columns upwards to start sky plate and needle plate, make it slowly leave circuit board, after leaving location-appropriate, drawer can be extracted out and take out circuit board, prepare the detection of next circuit board.Except being provided with probe bottom described needle plate, be also provided with reference column and vertical columns, reference column is placed in the surrounding of needle plate, and when needle plate is depressed into support plate position, vertical columns, by the surface being pressed in circuit board, ensure that circuit board does not deform, depart from or tilt phenomenon.The size of described circuit board is less than the size of Baltimore groove, and described vertical columns is perpendicular to bottom surface, Baltimore groove place.
In above-mentioned either a program preferably, be provided with connecting groove between the pedestal of this frock and sky plate, be used for switching on power; Bottom needle plate, be also provided with reference column, reference column is positioned at the surrounding of needle plate, and needle plate can be made like this when being depressed into support plate position, and vertical columns by being pressed on the surface of circuit board, thus ensure that circuit board steadily and do not depart from or tilt.This device can the whether short circuit of testing circuit plate, open circuit, filter out bad circuit board.
