Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the fingerprint module pressing and baking fixture of the present invention includes a bottom plate 1 having a plurality of cavities 11, an upper cover 2 having a plurality of upper air holes 21, and a plurality of connecting members 3 for fixing the upper cover 2 above the bottom plate 1, wherein the upper cover 2 is provided with a plurality of elastic pressing mechanisms 4 corresponding to the positions of the cavities 11, each elastic pressing mechanism 4 includes an elastic pressing block 41 and a spring thimble 42 for connecting the pressing block 41 to the lower side of the upper cover 2, and the spring thimble 42 can make the pressing block 41 have a tendency of being away from the upper cover 2. During the use, the product is placed in cavity 11 earlier, when upper cover 2 is fixed, every presses material piece 41 to correspond a product, accomplish fixed back at connecting piece 3, spring thimble 42 can produce certain compression, can utilize pressing material piece 41 to add the pressure that produces by elasticity to the product then, the product is prevented pressing by the elastic energy of pressing material piece 41, every elasticity swager constructs 4 and has independent elasticity situation, so can adapt to different product heights, ensure that every product is all firmly pressed in cavity 11, avoided the product to rock in the tool and drop.

As shown in fig. 2 and 3, two sides of the upper cover 2 are respectively provided with a notch 22, a connecting pad 5 is fixed under the upper cover 2 across the notch 22, two sides of the bottom plate 1 are provided with fixing holes 12, and the connecting pad 5 is fixed with the bottom plate 1 through a connecting piece 3 penetrating through the fixing holes 12. The connecting cushion block 5 can limit the distance between the upper cover 2 and the bottom plate 2, and the problem that the upper cover 2 is hard contacted with the upper surface of a product to cause poor surface scratches is avoided.
