Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a carrier tray cooling and cleaning system. Background Technology

[0002] Copper-clad laminate (CCL) serves as the substrate material in printed circuit board (PCB) manufacturing, primarily providing interconnection, insulation, and support. PCBs, also known as printed circuit boards, are crucial electronic components. During the high-pressure, high-temperature lamination process, the resulting board material reaches temperatures as high as 160-220 degrees Celsius. Even after passing through a cold press, the temperature remains around 80 degrees Celsius. Traditionally, natural cooling is used, but overlapping cooling methods result in slow cooling rates when the boards are stacked, affecting subsequent processing steps and reducing production efficiency. Furthermore, since the carrier trays do not operate continuously 24 hours a day, rust may occur under cyclical usage scenarios, impacting PCB quality.

[0003] In order to rapidly cool and clean the carrier disk, this application discloses a carrier disk cooling and cleaning system. Utility Model Content

[0025] Example

[0026] To address the issues in existing technologies where printed circuit boards (PCBs) typically rely on natural cooling of the carrier tray after high-temperature lamination, which impacts work efficiency and makes the PCB carrier tray prone to rust due to its short service life, thus affecting PCB quality, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a carrier plate cooling and cleaning system, comprising:

[0027] The chassis 10 is arranged along the first direction, and the two sides of the second direction inside the chassis 10 are respectively provided with sprocket conveyor lines 20 to drive the carrier plate to move together.

[0028] Several water spray pipes 30 are arranged along the first direction below the sprocket conveyor line 20 for continuous water spraying to cool the carrier plate.

[0029] Nylon brush 40, which is rotated and positioned between two water spray pipes 30, is used to clean the carrier plate;

[0030] A water suction wheel 50 is rotatably positioned behind several water spray pipes 30 to suction water from the carrier plate.

[0031] Several air knives 60 are positioned behind the water suction wheel 50 to air dry the carrier plate.

[0032] In practice, the tray to be cooled is placed on two sprocket conveyor lines 20 and gradually moves backward under the drive of the two sprocket conveyor lines 20. During the movement of the tray, several water spray pipes 30 will spray cooling water onto the bottom surface of the tray, thereby cooling the tray. When the tray passes the nylon brush 40, the nylon brush 40 will automatically clean the bottom surface of the tray. When the tray is cooled and cleaned, the two sprocket conveyor lines 20 transport the tray through the water suction wheel 50, which will absorb the water stains on the surface of the tray. Finally, the tray is dried by passing through the air knife 60.

[0033] In one specific embodiment, this application further includes a water circulation mechanism 70, which includes a wastewater treatment tank 71, a filter 72, a water supply tank 73, a heat exchanger 74, a return water pump 75, and a cooling pump 76. A drain outlet 11 is provided at the bottom of the casing 10. The wastewater treatment tank 71 is located at the bottom of the casing 10, directly opposite the drain outlet 11. The water supply tank 73, heat exchanger 74, return water pump 75, and cooling pump 76 are all located outside the casing 10. The filter 72 is located inside the wastewater treatment tank 71 and is connected to the return water pump 75 via a first water pipe 77. The return water pump 75 is connected to the water supply tank 73 via a second water pipe 78. The cooling pump 76 is connected to the water supply tank 73 via a third water pipe 79. The cooling pump 76 is connected to the heat exchanger 74 via the fourth water pipe 710. The heat exchanger 74 is connected to several spray pipes 30 via the distributor 711. When water is supplied to the spray pipes 30, the cooling pump 76 draws water from the water supply tank 73 to the heat exchanger 74 for cooling. The water is then delivered by the heat exchanger 74 to the spray pipes 30. The cooling water sprayed from the spray pipes 30 will fall into the bottom of the chassis 10 after cooling the tray. It will then be discharged into the sewage treatment tank 71 from the drain port 11 of the chassis 10. When the return water pump 75 draws water, the sewage in the sewage treatment tank 71 will be filtered through the filter 72 before entering the water supply tank 73. This cycle can save water resources.

[0034] Based on the above embodiments, this application also provides a sewage pump 712 outside the chassis 10. The sewage pump 712 is connected to the sewage treatment tank 71 through the fifth water pipe 713. After the sewage in the sewage treatment tank 71 is filtered, the sewage pump 712 will discharge the pollutants in the sewage treatment tank 71.

[0035] Based on the above embodiments, the water supply tank 73 of this application is connected to a purified water replenishment pipe 714. If the water resources in the water supply tank 73 are insufficient, water can be replenished to the water supply tank 73 through the purified water replenishment pipe 714, thereby ensuring that the water resources in the water supply tank 73 are always sufficient.

[0036] In a preferred embodiment, the heat exchanger 74 of this application is a plate heat exchanger 74. Of course, the specific structure of the plate heat exchanger 74 is known technology. Its function is to cool the water coming out of the water supply tank 73 and then deliver it to several spray pipes 30 for spraying.

[0037] In order to ensure that the air knife 60 can efficiently dry the carrier plate, the air outlets of the air knife 60 are arranged at an angle. When the air knife 60 dries the carrier plate, the air blown out by the air knife 60 will reach the bottom surface of the carrier plate at an angle.

They should not be construed as limiting the scope of protection of this utility model.
