[0002] In the process of printed circuit board (PCB), a gantry vertical electroplating line is usually used. Gantry vertical electroplating line is an automated equipment used for electroplating of printed circuit board (PCB). It adopts a gantry mechanical structure, which can realize the automatic transportation and positioning of PCB in the electroplating tank. In this electroplating line, PCB enters and exits the electroplating tank in a vertical manner, and the printed products are automatically lifted to each liquid tank and each cleaning tank by a crane for electroplating and washing.

[0029] The specific structure of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 to Figure 3 , Figure 1 This is a schematic diagram of an electroplating water washing system according to an embodiment of the utility model, which specifically includes:

[0031] Driving device,

[0032] A controller, used for controlling the traveling device to transport the parts to be cleaned;

[0033] A touch display screen is electrically connected to the controller;

[0034] A plurality of cleaning tanks 4 are used for electroplating cleaning of parts to be cleaned; a driving device is arranged above the cleaning tank 4, and the driving device is used to transport the parts to be cleaned to the cleaning tank 4; an address sensor is arranged on each cleaning tank 4, and the address sensor is electrically connected to the controller; the address sensor is used to sense the position of the driving device;

[0036] It should be noted that the controller can use a PLC logic controller to control the operating state and operating mode of the driving device, so that the driving device moves to a cleaning process to transport the parts to be cleaned to the cleaning tank 4. The operating state and operating mode of the driving device can be set through a touch screen. The electroplating water washing system includes a plurality of cleaning tanks 4. When the number of cleaning tanks 4 is multiple, the operator can set the driving route through the touch screen, and then the driving device transports the parts to be cleaned to each cleaning tank 4 in turn according to the driving route. The water replenishment port of the water replenishment device transports the cleaning liquid into the cleaning tank 4 through the first pipe 1 to wash in the cleaning tank 4. The first solenoid valve 11 on each first pipe 1 is controlled by the controller. When the address sensor on each cleaning tank 4 obtains and senses that the driving device is above, the address sensor transmits the relevant position information to the controller, and the controller opens the first solenoid valve 11 corresponding to the cleaning tank 4 to allow the cleaning liquid to flow into the cleaning tank 4 to complete the cleaning of the parts to be cleaned. The cleaning liquid can be pure water or other liquids that do not affect the performance of the parts to be cleaned. Furthermore, in some embodiments of the present invention, the touch screen and the controller can establish a connection using RS232 communication; each address sensor provided on the cleaning tank 4 is provided with a corresponding number, and the touch screen can display the working status of each address sensor.

[0039] In some embodiments of the present invention, each cleaning tank 4 is further provided with a conductivity meter and a pH meter; the conductivity meter and the pH meter are electrically connected to the controller respectively.

[0040] It should be noted that during the water replenishment process, the conductivity of the liquid in the cleaning tank 4 will change, so the water replenishment amount and replenishment time of the water replenishment device can be controlled by the conductivity of the liquid; the pH value of the cleaning liquid will change during the cleaning process, so the water replenishment time and cleaning time can be controlled by the pH of the liquid.

[0041] In some embodiments of the utility model, each water replenishment port of the water replenishment device is connected to the corresponding cleaning tank 4 through the first pipe 1; a flow sensor is arranged in each first pipe 1, and a water replenishment ball valve 12 is arranged on each first pipe 1.

[0043] In some embodiments of the present invention, the electroplating water washing system also includes a timer, and the timer is electrically connected to the controller.

[0044] It should be noted that the timer is used to control the duration of the water replenishing device replenishing the cleaning fluid, and the first solenoid valve 11 can be opened or closed at a fixed time according to the timer setting, so as to limit the duration of replenishing the cleaning fluid.

[0045] In some embodiments of the utility model, the electroplating water washing system further includes a plurality of first relays; all the first relays are electrically connected to the controller, and each first relay is used to attract the corresponding first solenoid valve 11 .

[0046] It should be noted that the controller can open the first solenoid valve 11 by energizing the first relay, and close the first solenoid valve 11 by de-energizing the first relay.

[0047] Reference Figure 3 In some embodiments of the utility model, the traveling device includes a traveling frame 31, a traveling slide rail 32, a lifting device and a clamping device 33; the traveling slide rail 32 is arranged above the cleaning tank 4, and the traveling frame 31 is slidably arranged on the traveling slide rail 32; the clamping device 33 is arranged on the traveling frame 31, and the clamping device 33 is used to clamp the parts to be cleaned; the lifting device is used to drive the lifting and lowering of the clamping device 33.

[0048] It should be noted that if Figure 3 As shown, in one embodiment of the present utility model, the controller can control the traveling frame 31 to move along the traveling slide rail 32 above the cleaning tank 4. Figure 3 In the middle cleaning tank 4, ①, ②, ③, and ④ represent the four cleaning tanks 4 in the production line. The traveling frame 31 reciprocates in sequence above ①, ②, ③, and ④, and controls the lifting device to lower or raise the clamping device 33 holding the parts to be cleaned, so as to realize the transportation of the parts to be cleaned. The traveling frame 31, the traveling slide rail 32, the lifting device, and the clamping device 33 are all controlled by the controller.

[0050] According to some embodiments of the utility model, the electroplating water washing system of the above-mentioned embodiment controls the position of the driving device through the PLC logic controller, specifically controls the movement of the driving frame 31 on the driving slide rail 32, and controls the lifting and lowering of the clamping device 33 through the lifting device. The operator can control the travel route and operation mode of the driving device through the touch display screen, so that the driving device passes through each cleaning tank 4 in turn and puts the parts to be cleaned into the cleaning tank 4. When the address sensor set on the cleaning tank 4 senses that the driving device is above the corresponding cleaning tank 4, the position information of the driving device is transmitted to the corresponding control end, so that the controller attracts the corresponding first relay, opens the corresponding first solenoid valve 11, and allows the cleaning liquid of the water replenishment device to flow into the cleaning tank 4. At the same time, the water replenishment time can be controlled according to the conductivity, pH value or timer set time of the cleaning liquid in the cleaning tank 4 to complete the water replenishment. The method of the above-mentioned embodiment realizes accurate water saving through fine control of the water replenishment of the cleaning tank 4, saves water washing costs, and avoids the waste of water resources.
