Abstract
The utility model discloses a steel ball drop impact test device for flexible part equipment high density circuit board, including base, vertical backup pad, drop a section of thick bamboo and inclined groove, vertical backup pad sets up perpendicularly on the base, and drop a section of thick bamboo and vertical backup pad parallel arrangement, and connect through a set of inclined groove between the two, it leaves certain distance to drop between a section of thick bamboo and the base. When the flexible part assembling high-density circuit board is used, the flexible part assembling high-density circuit board is placed on the bottom plate, the steel ball is put down from one of the inclined placing grooves, the steel ball rolls into the falling cylinder to fall freely, the steel ball hits the flexible part assembling high-density circuit board to complete an impact test, the falling height can be selected according to actual needs, and the operation is simple.
Description
Technical Field
The utility model relates to a circuit board test processing field specifically is a fall impact test device for flexible part equipment high density circuit board steel ball.
Background
The existing FPC part board needs to be subjected to drop impact resistance test before being delivered to a client to verify whether the impact resistance and the like of the FPC part board meet requirements, when the FPC part board is subjected to drop impact test, a steel ball is generally required to be manually lifted and manually dropped from different heights to impact FPCA to test, the manual test heights are different every time, the operation is inconvenient, the working strength is high, the test efficiency is low, the impact alignment degree of the FPCA is inconsistent every time, and finally the test result is inaccurate and unreliable.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to the problem and not enough of existence among the above-mentioned prior art, the utility model aims at providing a fall impact test device for flexible part equipment high density circuit board steel ball.
The technical scheme is as follows: in order to achieve the purpose, the falling impact test device for the high-density circuit board steel ball assembled by the flexible parts comprises a base, a vertical supporting plate, a falling cylinder and an inclined groove, wherein the vertical supporting plate is vertically arranged on the base, the falling cylinder and the vertical supporting plate are arranged in parallel, the falling cylinder and the vertical supporting plate are connected through a group of inclined grooves, and a certain distance is reserved between the falling cylinder and the base.
Furthermore, steel ball inlets are formed in the falling cylinder at equal intervals, and the lower end of the inclined groove is arranged at the steel ball inlets.
Furthermore, the arc-shaped groove is arranged on the vertical supporting plate far away from the steel ball. After the steel ball is used, the steel ball can be put in, and when the steel ball is used, the vertical supporting plate is put down, and the steel ball is taken out from the steel ball placing arc-shaped groove.
Further, the inclined groove includes 8, and parallel arrangement each other, the inclined groove is 30 +/-0.5 with the horizontal direction contained angle.
Further, the distance between the inclined groove at the lowest end below the falling cylinder and the base is 10cm, and the distance between adjacent inclined grooves is 10 cm. During drop test
Furthermore, the inner cavity of the inclined groove is semicircular, and the radius of the inner cavity of the inclined groove is larger than that of the steel ball.
Furthermore, a placing area to be tested is arranged below the falling cylinder on the base.
Above-mentioned technical scheme can see out, the beneficial effects of the utility model are that:
a be used for flexible part equipment high density circuit board steel ball drop impact test device, place FPCA on the bottom plate, can put down a plurality of steel balls from the slope standing groove in proper order, the steel ball rolls into and realizes freely falling in the falling section of thick bamboo, FPCA is hit to the steel ball, accomplish the drop test, so repeated many times, need not remove the FPCA's that awaits measuring position, can simulate the impact force that FPCA can bear effectively, high test efficiency, and the test height can be selected according to actual need, and is easy for operation, therefore, the clothes hanger is strong in practicability.
