A kind of etchant processing box handle

technical field

The utility model relates to the field of etching liquid, in particular to a handle of an etching liquid processing box.

Background technique

With the recovery of the electronics industry, the development of China's circuit board industry has also generally picked up. China will become the world's largest PCB industry base in recent years, accounting for about 30% of the global market. At the same time, Suining, Sichuan is currently the "Southwest Circuit Board (PCB) Industry Manufacturing Base" approved by the state. With the presence of PCB industry giants such as Positronics and Foxconn Electronics in Sichuan and Chongqing, and the relocation of a large number of circuit board factories along the coast, the PCB industry will continue to grow. Usher in a huge business opportunity.

According to the statistics of China's circuit board industry, there are currently more than 4,000 circuit board manufacturers in China, and less than 1.5% have installed etching solution recycling systems, which have great market prospects. If the online circulation technology of printed circuit board etching solution can be promoted in the entire PCB industry, more than 600,000 tons of copper can be recovered each year, and 5,000,000 tons of recycled etching solution can be reused, with direct economic benefits of more than 40 billion yuan; the annual etching process can be reduced The consumption of ammonium chloride is 1-1.5 million tons and the consumption of ammonia is 2-2.5 million tons, which can greatly reduce the production cost of etching production lines of PCB enterprises; it can reduce ammonia nitrogen emissions by more than 2 million tons and COD emissions by 4,000 tons every year, and greatly reduce the cost of PCB enterprises. waste discharge, thus having good social, environmental and economic benefits. After successfully developing the domestic market and gaining certain experience, it is possible to further expand the international market. With the advantages of low domestic development costs and strong professionalism, it is very possible to enter the product into the international market.

In the production process of printed circuit boards, etching is a very important process link, and because a large amount of etching solution must be used, it has also become a process that produces serious pollution sources. The traditional domestic treatment method is: the environmental protection department designates a qualified company to recycle the etching waste liquid. The main method is to use a simple method to process the copper contained in the waste liquid into copper sulfate, and then slightly treat it. emission. This not only causes a great waste of resources (in addition to copper in every 1000 liters of alkaline etching solution, there are more than 240 kilograms of ammonium chloride, about 30 kilograms of liquid ammonia and other chemical substances), and the waste liquid has not been truly recovered. The radical cure has formed the transfer of pollution sources. Since the etching solution is a toxic substance, it needs to be sealed, and the sealing is done by a large and heavy glass plate. The surface of the glass plate is smooth, and it is very inconvenient for the operator to carry it.

Utility model content

The purpose of the embodiment of the present invention is to provide a handle for the etching solution treatment box, the handle has a simple structure, low manufacturing cost, and is convenient for the operator to carry the etching solution treatment box without damaging the sealing performance of the etching solution treatment box, and The handle can be reused.

The handle of an etching liquid treatment box provided by the embodiment of the utility model includes a hand-held part, and a button is arranged on the top of the hand-held part, and the button is respectively connected to the ends of two levers arranged inside the hand-held part. The other ends of the levers are respectively connected to the pistons. The levers are L-shaped. When the button is pressed, the levers rotate around the fulcrum. Pistons, the pistons are respectively arranged in the connecting pipes communicating with the hand-held parts, and the bottoms of the connecting pipes are respectively arranged on the suction cups.

Optionally, 1 to 5 suction cups are provided at the bottom of each connecting pipe.

Optionally, the suction cup is circular.

Optionally, the bottom edge of the suction cup is provided with a circular miniature suction cup

It can be seen from the above that the technical solution of this embodiment is applied, and the structure of the suction cup is used to fix the handle to carry the etching solution treatment box. Since the etching solution treatment box is sealed with a glass plate, the smooth surface of the glass plate is conducive to the fixation of the suction cup, and it is convenient for the operator to handle the etching solution. The transport of the box does not damage the sealing performance of the etching solution processing box, and the handle can be used repeatedly. The handle has a simple structure and low manufacturing cost.
