Problems solved by technology

[0003] At this stage, China has not yet proposed a relatively complete solution for the batch processing of scrap membrane keyboards. Most products on the market can only be crushed as a whole, resulting in the mixing of parts of different materials, which has caused great trouble to subsequent processing.

Embodiment Construction

[0031] The content of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0032] First, give a brief introduction to the object of dismantling—the membrane keyboard, such as Figure 18 As shown, the common membrane keyboard connects the keyboard lower case 65 and the keyboard upper case 72 through bottom screws 64, and the position of the PCB board 70 inside the keyboard is relatively fixed. When the keyboard upper case 72 faces upward, the PCB board 70 is generally located on the upper right side, and the size of different keyboard PCB boards is similar. The PCB board 70 is fixed on the lower shell 65 of the keyboard together with the silicone cap 69, the upper film circuit 68, the insulating layer 67, and the lower film circuit 66 through the metal bead and the fixing screw 71. It should be noted that the internal structure of different keyboards is slightly different. , there is also a structure to invert the ...

Abstract

The invention aims to achieve batch processing and dismantling of scrapped membrane keyboards, and for the solution, provides a batch dismantling device for a scrapped membrane keyboard, which consists of a PCB dismantling module, a screw dismantling module and a housing and membrane part separation module, wherein the PCB dismantling module recognizes the position of a PCB through a metal detector; a crank-slider mechanism performs blanking, and automation is realized through electromagnetic control, a Hall element and the like; the screw dismantling module utilizes material characteristics in the scrapped keyboard to simultaneously heat up a plurality of screws, attracts the heated screws by an electromagnet, and proposes a control concept of continuous adsorption is put forward; and thehousing the membrane part separation module utilizes the fragility of a plastic housing and the flexibility of a membrane part, and realizes separation of the two through pulverizing and screening; and compared with a traditional electronic trash crushing mode, the batch dismantling device has the advantages of strong pertinence, high efficiency and good dismantling effect, and the cost in follow-up treatment is greatly lowered.

Description

technical field [0001] The invention relates to a solution for processing electronic waste, in particular to solve the problem of batch processing and dismantling of waste film keyboards. Background technique [0002] With the popularization of personal computers, the output of keyboards has also increased rapidly as an indispensable accessory. Membrane keyboards have occupied most of the keyboard market because of their simple structure and low price. Due to the short lifespan of the silicone part responsible for providing elasticity in the membrane keyboard, the membrane keyboard is damaged quickly, and because most of them are not expensive and the maintenance value is very low, once damaged, most of them are directly scrapped, resulting in a large amount of electronic waste. It is estimated that in 2017, the number of discarded membrane keyboards in China is about 5 million. Recycling only the plastic in the keyboard can generate tens of millions of value and has huge en...
