Blanking method for FPCA plate die cutting, die cutting method and die cutting device

Abstract

The invention discloses a blanking method for FPCA plate die cutting. The blanking method comprises the following steps that an upper die with suction holes moves away from a lower die, and meanwhile products adsorbed to the upper die is separated from the lower die; each product is sucked by at least one suction hole, and the multiple products formed through one-time die cutting are correspondingly sucked by all the suction holes in the upper die at the same time; material receiving discs are moved and positioned to the lower die, and the lower die drives the material receiving discs to move towards the upper die till the material receiving discs is attached to the upper die; and after the material receiving discs are attached to the upper die, suction force generated by the suction holes to the products is canceled, so that each product freely falls into a material frame of the corresponding material receiving disc. The invention further discloses a die cutting method and a die cutting device using the blanking method. The product loading operation is rapidly and efficiently completed, and the labor cost is reduced.

Description

technical field [0001] The invention relates to die-cutting of FPCA boards, in particular to a blanking method, a die-cutting method and a die-cutting device for die-cutting of FPCA boards. Background technique [0002] The current die-cutting method for the FPCA plate punching shape mainly includes manual assisted loading and unloading, and manipulator assisted loading and unloading. [0003] The die-cutting method of loading and unloading with manual assistance is as follows: the staff feeds the FPCA board onto the lower die according to the positioning hole on the FPCA board and the PIN on the lower die; The FPCA board is cut to form multiple products arranged on the lower mold; the staff uses a glue stick to suck each product from the lower mold; manually removes the product from the glue stick and puts it into the corresponding material frame of the receiving tray Inside. In this method, when the staff manually loads materials, since the positioning hole on the FPCA b...

AI Technical Summary

Problems solved by technology

Due to the small size of the product, it is difficult to ensure the precise alignment between the suction nozzle and the product itself.

Especially when it is necessary to ensure the precise alignment of multiple nozzles and multiple products at the same time

The error in the arrangement of multiple suction nozzles on the suction plate, the positioning error between the suction plate and the lower mold, etc. will increase the error when the suction nozzle absorbs the product and affect the suction effect

When the suction nozzle moves from the lower mold to the receiving plate with the suction plate after sucking the product, the vibration caused by the movement will also cause the product to fall, seriously affecting the work efficiency

For small products with a size of less than 5m*5m, since the size of the nozzle itself is about 3mm*3mm, the arrangement and positioning will cause an error of about 1.5mm, so that the nozzle cannot be aligned with the product, resulting in air leakage and other phenomena

Therefore, for small products, blanking can only be done manually
