Disassembly device for reusable surface-mounted components of waste circuit board

Abstract

The invention belongs to the field of recycling and reusing of electric product waste and discloses a disassembly device for reusable surface-mounted components of a waste circuit board. The disassembly device is composed of a heating system, a cooling system, a conveyer system, a sweeping system and a component collecting mechanism. The heating system is composed of heating areas. The cooling system is composed of a cooling area. The conveyer system is composed of a horizontally-installed conveyor chain, a driven chain wheel, a driving chain wheel, a U-shaped groove and a motor. The sweeping system is composed of sweeping mechanisms, the sweeping mechanisms on all stages are respectively provided with a left hairbrush and a right hairbrush, and the hairbrushes can be arranged in a rotating mode or a reciprocating mode. A hot air box is composed of a rectifying plate, a heater and a fan. The disassembly device for the reusable surface-mounted components of the waste circuit board has the advantages that the circuit board is conveyed through a retaining ring with a simple structure, thus, time is saved, and manufacturing cost is lowered; because the rectifying plate is vertically placed, the problem that the tiny surface-mounted components and solder enter small holes of the rectifying plate easily after the circuit board is heated and de-soldered is solved, line production can be realized, and efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of recycling and reusing electronic and electrical waste, and in particular relates to a reuse-oriented waste circuit board mounting type component dismantling equipment. Background technique [0002] Nowadays, the development of the electronic and electrical industry is advancing by leaps and bounds, and the replacement of electrical and electronic products is very fast, and a large amount of electronic waste is generated every year. If these electronic wastes are handled properly, they can be recycled and turned into treasures. Printed Circuit Board (PCB) is one of the most important components in electrical and electronic products. How to deal with a large number of discarded circuit boards has become a common problem faced by all countries. The usual treatment method is to extract metal materials. Another feasible method is to disassemble the components on the discarded circuit boards without damage and...

Problems solved by technology

The disadvantage is that the disassembly efficiency is low; the inertia of the motion mechanism in the vibration mechanism is too large, so the energy consumption is high and the noise is large; the roller brush can only sweep the back of the circuit board, which limits the improvement of disassembly efficiency

[0006] Patent CN102009242A invented a method of dismantling components by using hot air to heat and melt circuit board solder, mechanical vibration to disassemble components, and rolling brush to sweep both sides of the circuit board to disassemble components. The reusability of disassembled components is good, but there are the following disadvantages: the circuit board is placed horizontally with the face down, and during the heating and desoldering process, tiny chip components and solder will fall into the heating temperature zone under the circuit board Difficult to take out; the clamping efficiency of clamping the circuit board with clamps is low, and the heat absorbed by the clamps increases energy consumption
