Embodiment Construction

[0020] Referring to Fig. 1 and Fig. 2, the equipment for removing circuit boards with components of the present invention is composed of a frame, a transmission power device, a conveyor belt device, an auxiliary transmission device, a cutter, a cutter adjustment device, a pressing device, and a vacuum adsorption device. .

[0021] Frame 1: It is welded by square steel and steel plate, used to connect and fix the parts on it, and ensure its relative correct position.

[0022] Transmission power device: The transmission motor 6 is fixed on the frame, the belt is transmitted to the reduction box 5, and the required linear speed is achieved through the reduction box. The output end of the reduction box is the sprocket 2, which is driven by the chain 3 to the front roller (active) The conveyor belt runs; at the same time, another set of sprockets at the output end of the reduction box transmits the required linear speed to the small conveyor belt sprocket 8 through the small convey...

Abstract

The invention discloses a method and a device to dismantle a component-carrying circuit board. The circuit board is horizontally arranged in a conveyor belt, conveyed by the conveyor belt to above an evacuated container; at the same time, a small conveyor belt is arranged slantways above the conveyor belt and is pressed on the circuit board; with the collaborated function of the friction force and vacuum absorption force of the conveyor belt and the gravity and the elasticity of the small conveyor belt, the conveyor belt is fastened onto the conveyor belt; symmetrical rolling knives are arranged above the evacuated container and the conveyor belt, and the components are separated from the circuit board after the component-carrying circuit board is cut by the symmetrical rolling knives. The invention is adapted to the different thickness of the board, the clamping of the circuit board is tight, and the cutting operation of the symmetrical rolling knives ensures the exactness of the cutting and disengaging direction, rapid speed, and high efficiency and recycles the metal powder without causing pollution.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a method and equipment for removing a circuit board with components. Background technique: [0002] With the modernization of industry and agriculture and the advancement of science and technology, especially the rapid development of information technology, the replacement of electronic products has become more frequent, followed by piles of obsolete and scrapped electronic circuit boards, seriously affecting and destroying the ecological environment. . At present, the treatment of waste electronic circuit boards is still a major problem in the world, such as landfill, washing, incineration and other methods. The metals and polymer organics are difficult to degrade under natural conditions, and harmful components pass through water, air, Soil enters the environment where people live, causing potential, long-term, and irreversible harm to human health and the ec...
