Description

Technical Field

[0001] The utility model relates to the technical field of circuit developing equipment, in particular to a circuit developing equipment with a defoaming device. Background Art

[0002] Development refers to the process of revealing the latent image formed on film or printing plates by exposure using a reducing agent. PS plate development involves simultaneously revealing the image and text on the plate, achieving a printing surface and plate properties that meet printing requirements. A developer is a printing processing device that uses semi-automatic or fully automatic processes to complete the development, washing, gluing, and drying steps of the exposed printing plate in one go.

[0003] When the existing traditional circuit developing machine is in use, the principle of development is a saponification reaction. The product has strong wettability and thus forms foam. The use of chemical methods to add defoaming agents will increase the yellow residual glue in the developer, resulting in unclean development. In addition, when the traditional circuit developing machine is in use, it is not easy to be cleaned with water and residual film of the solution is likely to remain.

[0004] For example, the Chinese authorized patent with announcement number CN 213634099 U (a circuit developer with a defoaming function) is implemented by setting a rinsing section, a developing section and a water absorption roller. When the circuit developer is in use, after the printed circuit board is developed, it is transported by the line roller through the partition into the rinsing section, and the tap water is introduced through the tap water pipe. After being filtered by the filter, it is pressurized by the booster pump and enters the connecting water pipe, and then enters the spray pipe and the spray pipe. The developer on the surface of the printed circuit board is rinsed and sprayed out through the nozzle at the bottom of the spray pipe and the spray pipe. When passing through the water absorption roller, the residual developer is removed by the wiping action of the spray pipe and the water absorption roller to ensure that the water is washed thoroughly. The bubbles generated during the development process are eliminated by the mechanical pressure between the pressure rollers when passing through the pressure rollers, preventing the addition of defoaming agent from increasing the yellow residual glue in the developer and causing the problem of unclean development. This technical solution solves the above problems.

[0005] However, the technical solution of the utility model still has some technical problems. When the circuit developer flushes the printed circuit board, since some developer remains on the surface of the printed circuit board, when the circuit developer directly impacts the water on the upper end of the printed circuit board, a large amount of water is needed to flush out the developer remaining on the upper end of the printed circuit board, which seriously wastes water resources. At the same time, the water suction roller is used to remove the residual water on the upper end of the printed circuit board in the form of physical contact, which can easily cause damage to the printed circuit board.

[0006] To this end, a line developing device with a defoaming device is proposed. Utility Model Content

[0031] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a developer storage tank 3 is fixedly installed on one side of the front end of the upper end face of the upper top cover 2, and a developer discharge pipe 15 is provided between the developer storage tank 3 and the developer spray pump 4. A conveying and defoaming pressure roller 9 is installed inside the main body bracket 1. The installation of the conveying and defoaming pressure roller 9 can crush the foam on the outside of the printed circuit board when transporting the printed circuit board, thereby enhancing the practicality of the device. The conveying and defoaming pressure roller 9 is rotatably connected to the main body bracket 1 through a bearing.

Clean water A clean water injection pipe is fixedly installed at the input end of the flushing pipe 19, and a filter screen 23 is installed at the lower end between the side baffles 22 and the middle baffle 21.

[0032] Working principle: When in use, the conveying motor 10 drives the conveying and defoaming pressure roller 9 to rotate, so that the conveying and defoaming pressure roller 9 transports the printed circuit board. When the printed circuit board is moving, the developer spray pump 4 evenly sprays the developer inside the developer storage box 3 to the outside of the printed circuit board through the developer discharge pipe 15 and the developer spray pipe 14. When the device transports the printed circuit board, the conveying and defoaming pressure roller 9 squeezes and crushes the foam generated on the outside of the printed circuit board to remove the foam. Then, as the printed circuit board moves, the developer removal air pump 5 blows away part of the developer remaining on the outside of the printed circuit board through the developer removal pipe 16, thereby reducing the developer content on the outside of the printed circuit board. Next, the secondary reflux flushing pump 6 reuses the water used to clean the printed circuit board through the secondary water suction pipe 18 and the secondary reflux flushing pipe 17, so that the secondary water is sprayed on the upper end of the printed circuit board to wash the printed circuit board and remove the developer on the outside of the printed circuit board. Then the clean water flushing pump 7 injects clean water into the pipe and the clean water flushing pipe 19 sprays clean water on the upper end of the printed circuit board for the final cleaning of the printed circuit board, and finally the drying air pump 8 uses air to blow away the water on the upper end of the printed circuit board through the drying pipe 20. At this time, the clean water that has cleaned the printed circuit board flows back to the middle baffle 21 and the side baffle 22 through the reflux pipe 13, which is convenient for the use of the secondary reflux flushing pump 6. The device is equipped with a developer removal air pump 5 to cooperate with the developer removal pipe 16 to enable the printed circuit board to remove the developer from the upper end of the printed circuit board in advance before being cleaned with clean water, thereby reducing the amount of developer retained in the upper end of the printed circuit board, thereby making the developer cleaning faster and enhancing the use effect of the device. The installation of the secondary reflux flushing pump 6 can flush the printed circuit board that has not been washed with water with the water that has washed the printed circuit board again, thereby improving water utilization, reducing water waste, reducing the use cost of the device, and enhancing the practicality of the device. The installation of the drying air pump 8 can blow air on the upper end of the printed circuit board to dry the printed circuit board, effectively avoiding physical contact damage to the printed circuit board caused by the device during drying.
