Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leaching devices, and more specifically to a device for leaching copper powder from waste PCB boards. Background Art
[0002] PCB, or printed circuit board, is an important electronic component. As the support of electronic components, it is the carrier of electrical connection of electronic components. It is made of layers of different materials, pressed by heat and adhesive. Among them, the copper powder on the PCB is mainly used to form conductive lines and connection points. In the PCB manufacturing process, copper powder plays a vital role. First, copper powder is coated or deposited on specific areas of the insulating substrate to form conductive lines. These lines are channels for signal transmission between electronic components, ensuring that the circuits on the circuit board can work properly.
[0003] First, when the copper powder on the waste PCB needs to be recycled, the PCB needs to be placed in a leaching tank to separate the PCB from the copper powder through a solution. However, in order to soak more PCBs, the leaching tank is generally deeper, which makes it difficult to take out the PCB after copper removal.
[0004] Second: After the waste PCB board is soaked in the solution, a large amount of residue will remain at the bottom, and these residues will adhere to the surface of the leaching box, which will cause corrosion or damage to the leaching box in the long run.
[0005] Second: When processing the PCB, the reaction rate is slow and it is difficult to meet production needs. Utility Model Content

[0015] Technical effects and advantages of the utility model:
[0016] 1. The utility model places the waste PCB board in a placement basket and then places the solution in the leaching box, then places the vibrating rod between the leaching box and the placement basket, and then covers the top cover. At this time, the vibrating rod vibrates, and then the heating tube is heated by the controller to accelerate the reaction of the solution in the leaching box. By increasing the temperature in the leaching box through the vibrating rod, the diffusion and mass transfer of the solution can be promoted, the reaction or dissolution process can be accelerated, and the production efficiency can be improved.
[0017] 2. According to the utility model, when the waste PCB needs to be taken out from the leaching box after the reaction is completed, the telescopic rod moves on the inner sleeve through the cylinder, and the connecting block moves upward when the telescopic rod moves upward, and the connecting block is connected to the placement basket. When the placement basket moves upward, the PCB can be lifted upward to facilitate its removal, and the solution can be better contacted with the PCB through the setting of the through hole, and the solution can also flow out through the through hole when the placement basket is lifted, which is conducive to quickly taking the PCB out of the leaching box and avoiding the skin from being contaminated by the solution when people bend over.
[0018] 3. When a large amount of impurities remain at the bottom of the leaching box and need to be removed, the motor is started to rotate the driving gear. After the driving gear rotates, the first gear and the second gear start to rotate. At this time, the threaded rod starts to rotate, and the scraper on the surface of the threaded rod starts to move along the bottom inner wall of the leaching box and scrapes off the impurities attached to the bottom, which helps to keep the leaching box clean and prevent the impurities from corroding the leaching box and causing adverse effects.
