Abstract
The utility model discloses a circuit board probe detection device with an anti-scratch function. The device comprises a spring arrangement plate and a multilayer probe assembling plate which is arranged on the spring arrangement plate and is used for arranging a probe. The device is characterized by also comprising a circuit board arrangement seat which is installed on the spring arrangement plate through an elastic lifting apparatus and is disposed above the probe, wherein a through hole is arranged at a position, which is corresponding to the probe below the circuit board arrangement seat, on the circuit board arrangement seat. By using the circuit board probe detection device with the anti-scratch function, the scratches on the surface of a circuit board to be detected can be remarkably reduced, the lamination process of the circuit board is ensured to be stable, the detection precision is enhanced, and at the same time the surface of the device can be cleaned completely.
Description
Technical field
the utility model relates to a kind of circuit board checking tool, is specifically related to a kind of circuit board probe detection device with anti-scratch function.
Background technology
also more and more stricter for its appearance requirement when trending towards densification and complicated development along with surface-mounted integrated circuit now, substantially do not allow circuit board surface that any damage and cut are arranged.Yet in the detection of circuit board, the probe of traditional circuit-board probe detection device all dense distribution on hard plate material, between probe and probe usually with foreign material.Circuit board is in the process of downward activity pressing probe, and its surface is often easily scratched by hard plate material and foreign material.And conventional probe detection device lacks for circuit board and carry out the mechanism effectively supported, circuit board aprowl also can produce scuffing because of uneven.In addition, on hard plate material owing to being intensively distributed with probe, therefore for the comparatively inconvenience of the clean change of the foreign material between probe.
Summary of the invention
the utility model purpose is: a kind of circuit board probe detection device with anti-scratch function is provided, and this device can effectively reduce the scuffing for the circuit-under-test plate, and guarantees the steady of press fit of circuit boards process, is convenient to the clean of apparatus surface simultaneously.
the technical solution of the utility model is: a kind of circuit board probe detection device with anti-scratch function, comprise spring settle plate and be placed in spring settle on plate for the multilayer probe mounting plate of probe is set; Characterized by further comprising by the elastic lifting device and be installed on the circuit board placement seat that spring is settled on plate and is positioned at the probe top, the probe corresponding to below on described circuit board placement seat is provided with through hole.
further, the device of elastic lifting described in the utility model is spring pin, and described spring pin is routine techniques, the power that mainly provides the circuit board placement seat to pump.
further, two back-up blocks that the placement seat of circuit board described in the utility model is symmetrically set in the median plate both sides by median plate and one form, and described each back-up block all is installed on spring by described spring pin and settles on plate.Symmetrically arranged back-up block and spring pin can guarantee that the detected circuit plate keeps balance in upper and lower pressing, finally just with probe, contact, to reduce because the uneven and scuffing of generation in the pressing process of detected circuit plate.
further, the placement seat of circuit board described in the utility model is provided with flexo cushion, and described flexo cushion is provided with the through hole corresponding with the through hole on the circuit board placement seat of below.Flexo cushion can adopt conventional rubber, sponge etc. to make, in test pressing process its with the detected circuit plate between contact and belong to soft contact, even tiny dust is arranged on the detected circuit plate, the situation such as also be difficult for producing scuffing or weigh wounded.
further, described spring is settled in plate and is provided with the spring accommodation hole corresponding to probe, is provided with the spring offseted with probe in the spring accommodation hole.
during concrete the use, first the detected circuit plate is placed on the circuit board placement seat, makes itself and flexo cushion pressing, and then press down with probe and contact by the spring pin balance, until the sheet surface layer of circuit board placement seat and multilayer probe mounting plate closure fully.The link tester of detected circuit plate is crossed the probe conducting to checkout facility, detects judgement.
the utility model has the advantages that:
1. because probe is to contact by through hole with the detected circuit plate, the circuit board placement seat and on flexo cushion the multilayer probe mounting plate of detected circuit plate and hard is cut off, can effectively prevent that circuit board is scratched.
the pick-up unit surface residual dust of meeting or other foreign material in long-term use procedure, but be mainly the flexo cushion place rested on the circuit board placement seat, as long as to the flexo cushion removing surface.Because probe is positioned at the flexo cushion below, do not interfere flexo cushion equally, so the flexo cushion surfacing, cleaning is convenient and thorough.
the utility model guarantees that by circuit board placement seat and elastic lifting device the detected circuit plate is keeping balance in upper and lower pressing, effectively reduces because the uneven and scuffing that produces in the pressing process of detected circuit plate, and is conducive to improve accuracy of detection.
