Problems solved by technology

[0006] 1. Fixing or clamping the circuit board, as well as manual loading and unloading during the operation, make the removal efficiency of components low and not suitable for industrialization;
[0007] 2. Destructive removal makes components unable to be reused;
[0008] 3. Using air as the medium to heat the circuit board to melt the solder, the heat utilization efficiency is low and the energy consumption is large; while heating, the surface and internal temperature of the components are high, and the components will be heated unevenly and easily damaged , thereby affecting the reuse of electronic components;
[0009] 4. The structure of the equipment is complex and the operation is difficult. Non-directional heating in the air will accelerate the volatilization or oxidation of toxic elements in the circuit board or components, such as polychlorinated biphenyls, diphenylfuran, etc., causing environmental pollution and operator poisoning

Embodiment Construction

[0028] see figure 1 , figure 2 In this embodiment, the heating tank 1 and the vibrating table 8 are arranged side by side in the left and right sides. Above the heating tank 1 and the vibrating table 8, a reciprocating rotation in the vertical plane between the heating tank 1 and the vibrating table 8 is arranged, and The turning angle and speed of the turning arm 3a are adjustable, and the support frame 3 is fixedly connected to the turning arm 3a in the form of a cantilever. The height of the liquid level of the medium 1a, when the carrier 3 is turned over into the heating tank 1, the circuit board 27 to be processed floats on the liquid level of the heat-conducting medium 1a, in a heated state where the circuit board is on the bottom and the components are on top;

[0029] In specific implementation, the turning arm 3a is fixedly connected to the feeding shaft 5 in the form of a key connection, and the feeding motor 6 drives the feeding shaft 5 to rotate, thereby driving ...

Abstract

The invention relates to equipment capable of industrially implementing the entire dismantlement of a waste and old circuit board component. The equipment is characterized in that a heating groove and a vibrating table are arranged in parallel at the left and the right, an overturning arm capable of rotating left and right is arranged above the heating groove and the vibrating table and a supporting frame is fixedly connected to the overturning arm in a cantilever mode; the vibrating table is supported on a vibrating frame by a rubber damper; a vibrating screen gaze is arranged below the vibrating table towards the discharge side; a soldering flux collector is arranged at the bottom of the vibrating frame, the dismantled component is held by the vibrating screen gaze and granular solder fluxes fall into the solder flux collector through the vibrating screen gaze; a blanking rack consists of a row of support rods, a circuit board can be supported on the blanking rack, and the dismantled component and solder flux can fall off through the blanking rack; and a cover plate is linked with the blanking rack and the blanking rack and the cover plate are overturned towards the blanking side by the rotation of a blanking rotating shaft. The equipment is simple and practical and can be industrially produced.

Description

technical field [0001] The invention relates to an automatic equipment for industrially dismantling waste circuit board components, in particular to a device based on component reuse and integral non-destructive dismantling. Background technique [0002] The circuit board, referred to as PCB, is an indispensable part of electronic and electrical products. With the rapid development of the electronic industry and the continuous application of high technology, the number of waste electronic and electrical products has increased sharply, resulting in a large number of waste circuit boards, namely Circuit board with components. As a huge amount of electronic waste, waste circuit boards have brought great pressure to society and the environment. Analysis and experimental testing show that most of the components on the waste circuit boards are in good condition and can be used continuously; at the same time, because the components contain various toxic and harmful substances and ...
