Prepreg stacking device and stacking method

Abstract

The invention discloses a prepreg stacking device and a stacking method. The prepreg stacking device comprises a machine frame, wherein the machine frame is provided with a conveyor belt for transporting prepregs, a stacking rack for stacking the prepregs, a left mechanical arm and a right mechanical arm; the left mechanical arm and the right mechanical arm are arranged on the machine frame in a left-right movement mode and located above the stacking rack; and the left mechanical arm is matched with the right mechanical arm to stack the prepregs conveyed by the conveyor belt on the stacking rack in a left-right staggered mode. Therefore, the stacking method is more efficient without manual staggered stacking, a certain number of prepregs can be used as a stack, and the stacks are staggered, so that fetching is more convenient, the time and labor cost is saved, and the production efficiency is improved effectively.

Description

technical field [0001] The invention relates to the field of prepreg production, in particular to a stacking device suitable for prepregs and a stacking method based on the stacking device. Background technique [0002] Copper-clad laminate is the basic material for making PCB, and semi-cured is the basic material for making copper-clad laminate. Most prepregs use glass fiber cloth as a reinforcing material. The treated glass fiber cloth is impregnated with resin glue, and then heat-treated (pre-baked) Made into a prepreg. A certain number of prepregs are overlapped and covered with copper foil on both sides, and the copper clad laminate is formed by hot pressing. [0003] After the prepregs are manufactured, they are usually neatly stacked together. Since a certain number of prepregs need to be separated into a stack when making copper clad laminates, so as to be sent to the hot-pressing process in turn, the existing distinction method is to manually separate the prepregs ...

Problems solved by technology

[0003] After the prepregs are manufactured, they are usually neatly stacked together. Since a certain number of prepregs need to be separated into a stack when making copper clad laminates, so as to be sent to the hot-pressing process in turn, the existing distinction method is to manually separate the prepregs into one stack. The stacked prepregs are re-stacked, that is, each stack of prepregs is staggered from each other. Although it can meet the requirements of the subsequent hot-pressing process, the manual stacking method is time-consuming and laborious, which is not conducive to reducing labor costs. It is also prone to failure of each stack of prepregs The inconsistency of stacking quantity will adversely affect the quality of copper clad laminates
