Dual-purpose reinforcing tube for cleaning and blow-drying of PCB automatic equipment

Abstract

The utility model provides a dual-purpose reinforcing tube for cleaning and drying PCB automation equipment, comprising a plastic tube, one side in the plastic tube is provided with a through hole, the other side in the plastic tube is provided with a reinforcing hole, the reinforcing hole is internally provided with a metal material, two ends of the reinforcing hole are provided with sealing plates which are matched and connected with the reinforcing hole, and the sealing plates are connected with the plastic tube. The problems that if a water and gas conveying pipe of an existing PCB automatic cleaning device adopts a metal pipe for conveying, in the manufacturing process of a high-precision PCB, the crystallization phenomenon still exists when the metal pipe conveys liquid, the fault probability of the PCB can be increased, and the manufacturing cost of the metal pipe is high; if a plastic water and gas conveying pipe is adopted, although the pipe does not generate metal ions, high-pressure gas or high-pressure liquid needs to be adopted for cleaning the PCB, a common plastic pipe is limited in structural strength, and the water and gas conveying pipe is bent due to too high pressure and temperature. And the high-pressure water delivery requirement of the PCB is difficult to meet.

Description

Technical Field

[0001] The utility model mainly relates to the technical field of conveying pipes, and in particular to a dual-purpose reinforced pipe for cleaning and drying PCB automation equipment. Background Art

[0002] The main function of PCB automated cleaning equipment is to thoroughly remove dust, substrate debris, green oil residue, micro-metal particles, fibers, hair and other impurities on the substrate surface and in the holes, and recycle these impurities, thereby improving printing quality, product yield and reliability.

[0003] During the operation of the PCB automatic cleaning equipment, water and gas pipes are required to transport the clean gas or cleaning liquid. When the PCB automatic cleaning equipment is working, the clean gas and cleaning liquid will be directed at the PCB circuit board for cleaning.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] Currently, there are generally two ways to transport water and air in automated PCB cleaning equipment. One is to use metal pipes for transportation. However, during the high-precision PCB production process, when the metal pipes transport liquid, trace amounts of metal ions will crystallize in the pipes and be sprayed onto the PCB surface along with the cleaning liquid, increasing the probability of PCB failure. Metal pipes are also expensive to manufacture. Another method is to use plastic water and air pipes. Although these pipes do not produce metal ions, since PCB cleaning requires high-pressure gas or high-pressure liquid for cleaning operations and generates high temperatures, the structural strength of general plastic pipes is limited. Excessive pressure can cause the water and air pipes to bend and deform, making it difficult to meet the cleaning and drying needs of PCB substrates.
