Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, and in particular to a solder mask production line device applied to an ultra-roughening section. Background Art

[0002] The solder mask production line is used to make solder mask on PCB boards. The solder mask is a layer of solder mask ink covering the surface of the PCB. The solder mask ink is applied to the circuits and substrates of the PCB that do not need to be soldered to prevent bridging between circuits during welding and cause short circuits. Before preparing the solder mask, the PCB board often needs to be ultra-roughened. By spraying ultra-roughening solution and micro-etching, an average and fine organic metal rough surface is produced to improve the bonding strength between the surface and the oil film coating.

[0003] Since the super-roughening solution is a copper surface roughening treatment liquid based on formic acid and cupric chloride, some of the solution remaining on the PCB board after super-roughening will cause corrosion to other equipment in the solder mask production line and affect the life of the equipment. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a solder mask production line device applied to the super-roughening section. By setting a cleaning component and a hot air blower, after the PCB board is cleaned, the hot air flow generated by the hot air blower flows upward from the gap between the transmission rollers, contacts the PCB board for heating and drying, so that no liquid medicine remains on the PCB board, avoiding corrosion of other equipment.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A solder mask production line device applied to an ultra-roughening section comprises a transmission component, a cleaning component and a drying component, wherein the transmission component comprises a plurality of rotatable transmission rollers, the plurality of transmission rollers are arranged in parallel at intervals, and the cleaning component and the drying component are sequentially arranged above the plurality of transmission rollers along the transmission direction;

[0007] The drying component comprises a hot air blower, which is arranged below the transmission roller, and the air outlet of the hot air blower faces the PCB board;

[0008] The PCB board after the super-roughening treatment is transferred by the transfer roller, cleaned by the cleaning component, and then dried by the hot air blower.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] By setting up a cleaning component and a hot air blower, after the PCB board is cleaned, the hot air flow generated by the hot air blower flows upward from the gap between the transmission rollers, contacts the PCB board for heating and drying, so that no liquid medicine remains on the PCB board, avoiding corrosion of other equipment.

[0011] As a preferred embodiment of the utility model, the drying component also includes an exhaust duct, which is arranged above the transmission roller. A fan is arranged in the exhaust duct to guide the hot air flow generated by the hot air blower into the exhaust duct.

[0012] Beneficial effect: By setting up the exhaust duct, the hot air flow is directed into the exhaust duct to prevent the residual liquid medicine from volatilizing into the air and affecting the environment.

[0013] As a preferred embodiment of the utility model, the drying component also includes a guide plate, which includes a horizontal plate and two inclined plates. The horizontal plate is arranged between the exhaust duct and the transmission roller, and the two inclined plates are respectively fixedly connected to both sides of the horizontal plate. The side of the inclined plate away from the horizontal plate is lower than the side close to the horizontal plate. The PCB board is located below the horizontal plate and between the two inclined plates.

[0014] Beneficial effect: By setting the guide plate, the hot air flow is blocked by the PCB board, flows upward from both sides of the PCB board, and is then blocked by the inclined plate. Part of the air flow moves horizontally and contacts the upper surface of the PCB board, accelerating the evaporation of moisture on the PCB board and improving the drying effect.

[0015] As a preferred embodiment of the utility model, the transmission roller includes a rotatable shaft body, both ends of the shaft body are fixedly connected with mounting rings, a spiral belt is fixedly connected between the two mounting rings, and the PCB board is located above the spiral belt.

[0016] Beneficial effect: By setting a spiral belt for conveying, the hot air flow can directly pass through the spiral belt and contact the PCB board, reducing the overall obstruction of the transmission roller to the air flow, increasing the contact area between the PCB board and the hot air flow, and improving the drying effect.

[0017] As a preferred embodiment of the present invention, the thickness of the spiral band is D1, and the pitch of the spiral band is D2;

[0018] D2>2D1.

[0019] Beneficial effect: When the pitch and thickness of the spiral belt satisfy D2>2D1, the hot air flow is less blocked by the spiral belt and can rise straightly through the gaps between the spiral belts to contact the PCB board, ensuring the drying effect. BRIEF DESCRIPTION OF THE DRAWINGS
