Abstract
A waste circuit board dismantling device capable of automatically separating components comprises a housing, an electric heater and a fan, and is characterized in that a rotational rotary drum for placing waste circuit boards is mounted in the internal heating space of the device, and meshes for accessing the components are disposed on the drum wall of the rotary drum. The waste circuit board dismantling device can realize the purpose of automatically dismantling circuit boards, and has the advantages that the efficiency is greatly increased compared with manual dismantling and cleaning, as the hot blast temperature of the internal heating space of the device is controllable and adjustable, the temperature of the hot blast is set to melt tin stain and also to avoid separation of paint from the printed circuit boards, thereby greatly reducing generated waste gas, and as the internal heating space is nearly sealed during operation, the hot blast is recycled, thereby saving energy and also further reducing the waste gas discharged in air.
Description
Technical field
The present invention relates to a kind of electromechanical equipment.
Background technology
The dismounting of the circuit board of waste electrical equipment and recycling are efforts at environmental protection that become more and more important, present technology, some external sophisticated equipments are that circuit board is pulverized together with element, and then adopt method such as washing to separate, equipment investment is very big, and the element on the plate also pulverized together, can't recycle; And the more original mode of general at home still employing: manual circuit board is positioned over roasted above the coal stove, with melts soldering tin, element beaten again or presss from both sides with pliers.Because the temperature of coal stove is difficult to grasp, too high temperature usually causes pcb board and top paint to decompose, and produces a large amount of poisonous fumes, directly is discharged in the air, cause serious air pollution, and efficient hand-manipulated is very low.
Summary of the invention
Purpose of the present invention is to disclose a kind of automatic equipment that element is disassembled and separates from waste and old circuit board that is used for.
The present invention includes equipment shell, surround the device interior heating space form, be used for the heater that the air to the device interior heating space heats by shell, it is characterized in that: the inside heating space of equipment is equipped with rotating turning barrel, turning barrel has closable for the window that drops into waste and old circuit board, and the bucket wall of turning barrel is provided with the mesh that can supply element to pass through.
Described electric heater is connected with temperature adjustment and temperature regulating device.Dismounting equipment also is provided with fan, comprises the fan page or leaf that is installed in the inside, device interior space, and the fan page or leaf is connected with the motor of enclosure by rotating shaft.
When working, the present invention drops into the waste and old circuit board that needs dismounting toward the turning barrel the inside by the dog-house of shell and the window of turning barrel, adopting heater and fan to produce hot blast at the inside of equipment heating space comes the waste and old circuit board of turning barrel the inside is heated, make the melts soldering tin of waste and old circuit board, and when turning barrel rotates owing to the collision between the waste and old circuit board, fall and rub, scolding tin and element on the circuit board are come off, and from the mesh of turning barrel, drop, thereby separate with the circuit board of turning barrel the inside, realize the purpose of automatic dissembling waste and old circuit board.Its positive effect is to have improved efficient widely than manual unpicking and washing, and because the hot blast temperature of device interior heating space can be in harmonious proportion controlled, the temperature of setting hot blast can make the fusing of tin point, unlikely again pcb board and the paint of causing decomposes, greatly reduce the generation of waste gas, because it is device interior heating space when work, hot air circulation was used near closed state, not only energy-conservation but also further reduce and be discharged into airborne waste gas.
As improvement, enclosure is provided with dividing plate, and dividing plate is divided into working space and heat production space with the device interior heating space.Working space is installed the working space of turning barrel as heating and dismounting circuit board, and the heat production space is used to install electric heater air is heated.Dividing plate is used for protecting electric heater in order to avoid be damaged in field-strip, improves electrical safety performance.
As another improvement, below turning barrel, be provided with cancellated element separator disk, be used for automatically electronic component being separated with tin, further improve automaticity and increase work efficiency.
