As shown in fig. 1 and 2, an embodiment of the present utility model proposes a lead frame detection fixing device, which includes a base 1, a support plate 2, and a fastener.
Specifically, two moving guide grooves 3 are arranged on the base 1, and the two moving guide grooves 3 are arranged in parallel. The support plate 2 is used for supporting and fixing the lead frame, two support plates 2 are arranged, and the support plate 2 changes the supporting and fixing width of the lead frame by sliding in the moving guide groove 3. The fastener is detachably connected with the supporting plate 2, and the fastener is used for fixing the position of the supporting plate 2 on the base 1.
When the lead frame to be detected needs to be positioned and fixed, the distance between the two support plates 2 is adjusted according to the size of the lead frame. Then, after the adjustment of the spacing of the support plates 2 is completed, the support plates 2 are fixed by using fasteners, and the support plates 2 are prevented from being offset. Finally, the lead frame is placed into the fixing groove 5 of the supporting plate 2, and the fixing operation of the lead frame can be completed, so that the structure is simple, and the operation is convenient.
In a specific embodiment, a movable slot 4 penetrating through the movable guide slot 3 is arranged on the side surface of the base 1, and the movable slot 4 is used for the fastener to penetrate through and be detachably connected with the movable slider 6. The movable groove 4 is arranged, so that the fastener can be conveniently moved, and the supporting plate 2 is fixed.
