Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 3-11, a stamping part and PSA protective film stepping laminating apparatus includes an upper die 10 and a lower die 20, the upper die 10 includes an upper die base 11, an upper padding plate 12, an upper clamping plate 13, a stripping plate 14 and a stripping plate 15 from top to bottom, the lower die 20 includes a lower die base 21, a lower padding plate 22 and a lower die plate 23 from bottom to top, the upper clamping plate 13 is provided with a plurality of punches 40, a side portion of the upper padding plate 12 is provided with an air suction port 30, the air suction port 30 is communicated with the plurality of punches 40 through an air suction duct, the air suction duct includes a main air suction duct 31 communicated with the air suction port 30 and a sub air suction duct 32 provided in each punch 40, the lower die plate 23 is provided with a groove (not shown in the drawing), a knife edge block 50 is provided in the groove, the floating material guiding assemblies 60 are arranged on two sides of the knife edge inlet block 50 along the product discharging direction, each floating material guiding assembly 60 comprises a floating material block 62 and a material guiding plate 61 arranged in the floating material block 62, an ejecting pin 63 is mounted at the bottom of the floating material block 62, a through groove (not shown in the drawing) for accommodating a PSA protective film 80 to pass through is arranged at the bottom of the knife edge inlet block 50 in the lower template 23, the discharging direction of the stamping part and the PSA protective film are divided into two types according to the requirement of equipment, one type is that the discharging direction of the stamping part 70 is perpendicular to the feeding direction of the PSA protective film 80 (as shown in FIG. 11), and the other type is that the discharging direction of the stamping part 70 is parallel to the feeding direction of the PSA protective film 80 (as shown in FIG. 10).
