Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Detection structure partial top view schematic diagram shown in shrapnel detection device schematic diagram as shown in Figure 1 and Fig. 3, shrapnel inspection
Measurement equipment includes board 1 and the lifting platform 7 on board, further includes guide post 6 described in the guide post 6 being arranged on lifting platform 7
Pressure value can be set, and setting compression spring, in the conduction testing machine 4 of board 1, puts with what conduction testing machine 4 was connected in guide post 6
The pcb board 5 in board 1 is put, the pcb board 5 is provided with sheet metal 2, the first metal ring plate 2a and the second metal ring plate 2b, metal
Piece 2, the first metal ring plate 2a and the second metal ring plate 2b are the same center of circle, and the radius of sheet metal 2 is less than the first metal ring plate 2a
Least radius, the maximum radius of the first metal ring plate 2a is less than the least radius of the second metal ring plate 2b, sheet metal 2 and first
Gap is 0.2 millimeter between metal ring plate 2a, and gap is 0.1 millimeter between the first metal ring plate 2a and the second metal ring plate 2b.
Pcb board 5 is provided at both ends with anchor point 14, and product is provided at both ends with location hole, and location hole is all caught on anchor point 14 so that production
Product need the accurate location of mounting elastic sheet and sheet metal 2 is the same center of circle.In known product single shrapnel by 1.6 newton power
It can deform upon from intermediate projections state and become flat state.Product is placed on pcb board 5, lifting platform 7 is adjusted and utilizes and lead
Guide post 6 is set as the shrapnel under the power of 2 newton on die pressing product by the compression spring in column 6.Guide post 6 push shrapnel, when shrapnel with
When 2 and first metal ring plate 2a of sheet metal is contacted and do not contacted with the second metal ring plate 2b, conduction testing machine 4 detects sheet metal
2 and first metal ring plate 2a conductings and the second metal ring plate 2b be not turned on, conduction testing machine 4 shows that position shrapnel installation is closed
Lattice.Guide post 6 pushes shrapnel, and when shrapnel is contacted with the second metal ring plate 2b, conduction testing machine 4 detects sheet metal 2 and second
Metal ring plate 2b is connected or the first metal ring plate 2a and the second metal ring plate 2b conductings, that is, deviation occurs for shrapnel installation,
Conduction testing machine 4 shows that the position shrapnel installation is unqualified.Guide post 6 pushes shrapnel, when shrapnel and sheet metal 2, the first becket
