Cleaning and cooling devices for electroless plating production lines

Abstract

This invention provides a cleaning and cooling device for electroless plating production lines, suitable for electroless plating processes with a hoisting mechanism and multiple treatment tanks. The hoisting mechanism includes an overhead crane equipped with a slingshot for suspending racks that carry the products to be treated and move with the crane between the treatment tanks. The cleaning and cooling device is mounted on the overhead crane and includes a spraying module and a water supply unit. The spraying module is positioned above the racks and sprays the products to be treated. The water supply unit is fluidly connected to the spraying module and supplies cleaning liquid. By moving with the overhead crane above multiple treatment tanks and spraying from top to bottom, the products to be treated are cleaned, and chemical residue is reduced, achieving both cleaning and cooling effects.

Claims

1. A cleaning and cooling device for an electroless plating production line, the electroless plating production line comprising a hoisting mechanism and a plurality of processing tanks, wherein the hoisting mechanism includes a crane configured to move between the processing tanks and having the capability of reciprocating vertical movement, the crane being equipped with at least one target for suspending a hanger for carrying a product to be processed, characterized in that the cleaning and cooling device comprises: A spraying module is installed on the overhead crane and positioned above the hanging rack, with a spraying direction toward the product to be treated; and a water supply unit is fluidly connected to the spraying module to supply a cleaning liquid to the spraying module; wherein, when the target suspends the hanging rack and the product to be treated is positioned above the treatment tank, the spraying module sprays the cleaning liquid, causing the liquid adhering to the product to be treated to flow downwards, thereby cleaning and cooling the product.

2. The cleaning and cooling device as claimed in claim 1, wherein the spraying module includes a plurality of nozzles disposed in a peripheral area above the rack and respectively directed toward the product to be treated carried on the rack.

3. The cleaning and cooling device as claimed in claim 2, wherein the spraying module is mounted on a nozzle base for supporting and positioning the nozzles, and the nozzle base is fixed to the overhead crane.

4. The cleaning and cooling apparatus as claimed in claim 1, wherein the water supply unit includes a liquid storage container for storing the cleaning liquid.

5. The cleaning and cooling device as described in claim 4, wherein the water supply unit further includes an inlet pipe and an outlet pipe, the inlet pipe being connected to the storage container for introducing the cleaning liquid into the storage container, and the outlet pipe being connected to the storage container and the spraying module for delivering the cleaning liquid in the storage container to the spraying module.

6. The cleaning and cooling device as described in claim 5, wherein the water supply unit includes a solenoid valve disposed on the liquid inlet pipe for controlling the opening or closing of the liquid inlet pipe.

7. The cleaning and cooling device as described in claim 6, wherein a liquid level sensor is provided in the liquid storage container, the liquid level sensor is electrically connected to the solenoid valve, for sensing the water level of the cleaning liquid in the liquid storage container, and when the water level is lower than a preset value, sending a water replenishment signal to the solenoid valve, causing the solenoid valve to control the opening of the liquid inlet pipe to introduce the cleaning liquid.

8. The cleaning and cooling device as claimed in claim 4, wherein the water supply unit includes a drive motor disposed between the liquid storage container and the spraying module for driving the delivery of the cleaning liquid.
