In the present embodiment, needle bed component 3 also includes being vertically and fixedly provided with the guide plate 32 for being located at the top of needle-bar 31, needle-bar 31
Lead 313, guide plate 32 can be slided up and down by lead 313 with respect to needle-bar 31, be provided between guide plate and needle-bar 31
Spring, guide plate 32 offers guide hole 321 in the corresponding position of testing needle.Guide plate 32 is mainly oriented to testing needle,
In the presence of spring, certain gap is kept between guide plate 32 and needle-bar 31, mainboard to be detected is positioned on guide plate 32,
During detection, mainboard is pressed down, and drives guide plate 32 to push together, testing needle stretches out from guide hole 321, is connected to the detection of mainboard
Point on.After the completion of test, pressure is removed, and guide plate 32 is moved up again under the action of the spring, and testing needle contracts from guide hole 321 again
Return.Guide hole 321 can be oriented to testing needle, be prevented after multiple test, testing needle bending, and lead to not touch mainboard
Abutment, it is impossible to detect signal.Spring can be sheathed on outside lead 313, be easy to spring to fix.For the ease of fixed to mainboard
Position, prevents mainboard from moving, and the upper surface of guide plate 32 offers the receiving area 322 adaptable with the shape of mainboard to be tested,
Accommodate to be provided with locating dowel 323, mainboard to be tested in area 322 and offer corresponding hole, mainboard is placed in receiving area 322
When, hole and locating dowel 323 coordinate, and accommodate area 322 and locating dowel 323 jointly positions mainboard, prevent mainboard from moving, it is ensured that survey
The reliability of examination.
Support member 2 and needle-bar 31 interfix for convenience, again convenient dismounting, and support member 2 is set to the frame of upper opening
Shape structure, the lower surface of needle-bar 31 is vertically and fixedly provided with four screen posts 314, and screen post 314 is caught in the inner side of frame-shaped construction.Utilize
Screen post 314, in that context it may be convenient to which needle-bar 31 is caught in support member 2, avoids movement in the horizontal direction, and changes conveniently, only
Need upwards to take out needle-bar 31.The quantity of screen post 314 can be adjusted according to actual conditions, it is however generally that, most
Three screen posts 314 should be set less, and three screen posts 314 are triangularly arranged, rather than arranged in straight line, with from
Three directions can block needle-bar 31, it is to avoid needle-bar 31 is moved.
In the present embodiment, mainboard test device also includes the pressing plate 5 for being located at the top of needle bed component 3, the top of pressing plate 5 and gas
Cylinder 6 is connected, and the bottom of pressing plate 5 is vertically installed with four compression legs 51.Because the bottom surface of mainboard is directly contacted with guide plate 32, typically
By the component side of mainboard upward, both avoided element from being damaged by pressure by guide plate 32, entered when being easy to testing needle to reach upper end from bottom again
Row test.Cause the element on mainboard to damage by pressure in order to avoid pressing plate 5 is directly pushed, compression leg 51 can be set in the bottom of pressing plate 5,
The position that compression leg 51 avoids element is set.Four compression legs 51 can reduce pressure of the compression leg 51 to mainboard, the actual number of compression leg 51
Amount can carry out its adjustment according to the actual requirements, typically at least provided with two compression legs 51.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, it will change in specific embodiments and applications, this specification content should not be construed as
To limitation of the present utility model.
