Description

TECHNICAL FIELD

[0001] The utility model relates to automatic vacuum breaking plate dismounting device technical field, concretely is a kind of automatic vacuum breaking plate dismounting device. BACKGROUND

[0002] Copper-clad plate needs to pass through high temperature, high pressure, vacuum laminating process in manufacturing process, to ensure that each layer material (such as prepreg, copper foil etc.) is completely solidified and bonded together to form integral structure under heat and pressure condition;In actual manufacturing process, in order to improve production efficiency, multiple copper-clad plates are often simultaneously laminated, and are sequentially stacked in the order of steel plate, copper-clad plate, steel plate, copper-clad plate, steel plate……, the number of copper-clad plates in each lamination cavity (usually referred to as Book) is 16~24, since copper-clad plate is laminated under vacuum state, the adjacent copper-clad plate and steel plate in the same lamination cavity still maintain a certain vacuum state after lamination, for example, there are still many vacuum points on the contact surface between copper-clad plate and steel plate;

[0003] When copper-clad plate is disassembled (usually referred to as plate dismounting), if there are still many small vacuum points on the contact surface between copper-clad plate and steel plate, steel plate will be adsorbed with copper-clad plate, when crane is sucking steel plate, on the one hand, steel plate may suck the underlying copper-clad plate, on the other hand, it may also cause that only plate corner can be lifted when vertically lifting plate, and the vacuum points between copper-clad plate and steel plate cannot be completely destroyed, so plate lifting is blocked;In order to overcome this problem, steel plate can be slid for a certain distance, so that the vacuum state between steel plate and copper-clad plate can be destroyed, so that plate material can be more easily lifted;In actual operation, before crane sucks steel plate, the operator needs to manually slide steel plate with suction cup to release vacuum;

[0004] Before crane sucks steel plate, the operator manually destroys vacuum with suction cup, on the one hand, there is a safety hazard, the operator may be injured by crane or hit by steel plate, on the other hand, if the operator makes a mistake, vacuum may not be successfully destroyed, and when steel plate is sucked, the underlying copper-clad plate may be sucked, so as to cause surface damage of copper-clad plate and affect product quality.
