Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB production, in particular to a pressure gauge alarm device for PCB production. Background Art
[0002] During the production process of PCB, nozzle blockage or filter bag blockage occurs, and visual inspection is required to find out that the water washing pressure gauge is lower than the lower limit control. Only by indirectly checking the reason why the pressure gauge is lower than the lower limit can the nozzle or filter bag be found to be blocked, and then it can be disassembled and cleaned.
[0003] However, manual troubleshooting is not only time-consuming and labor-intensive, but also fails to detect problems in a timely manner, which will lead to abnormal quality of PCB products. For example, if the nozzle or filter bag of the grinding brush section is clogged, high-temperature friction will occur between the needle brush and the PCB during dry grinding, leaving residual glue on the PCB surface. If the etching pressure is lower than the lower limit, it will lead to incomplete etching and short circuit of the entire board, which will have a certain impact on the quality of the PCB and may even cause the PCB to be scrapped.

[0006] Preferably, the master control screen sets the value of each pressure gauge individually.
[0007] Preferably, when the value of the pressure gauge on the display screen is within a normal range, the three-color light is green.
[0008] Preferably, when the value of the pressure gauge on the display screen is out of range, the main control screen controls the buzzer to emit a buzzer sound and the three-color light switches to red.
