DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-4, a device for quickly removing ink from the copper foil of a PCB board, including a machine body 1. There is a cleaning tank 2 at the upper part of the machine body 1. On one side away from the cleaning tank 2, an installation block 5 is installed by being driven by a transverse movement mechanism 4. In the middle of the installation block 5, a driving rod 111 is installed through a driving motor 11. A brush roller 6 is installed on the driving rod 111 by being clamped through a key block 112. And at the other end of the driving rod 111, a rotating cover plate 10 is installed by being screwed through a threaded section 113.

[0023] Furthermore, spray racks 8 and air jet racks 9 are respectively installed on both sides of the installation block 5. The spray racks 8 and air jet racks 9 are respectively connected to an external water pump and air pump through connecting pipes, so as to achieve the purpose of the spray racks 8 spraying cleaning liquid and the air jet racks 9 spraying high-speed gas.

[0024] Furthermore, a waste water pipe 3 is installed on one side of the machine body 1. The waste water pipe 3 is communicated with the cleaning tank 2 to achieve drainage, and then the waste water is recycled and treated.

[0025] Furthermore, a transverse movement mechanism 4 is installed on one side of the upper part of the machine body 1. An installation block 5 is installed on the transverse movement mechanism 4 in a limited way.

[0026] Furthermore, sliding grooves 21 are respectively opened on both sides of the cleaning tank 2. A plurality of locking rods 7 are installed in the sliding grooves 21 in a limited sliding way. A threaded hole is opened in the middle of the locking rod 7. A locking bolt 71 is installed in the hole by being screwed. The bottom end of the locking bolt 71 passes through the bottom wall of the locking rod 7 and is in frictional contact with the upper surface of the cleaning tank 2.

[0027] Furthermore, a driving motor 11 is installed in the middle of the installation block 5. The output end of the driving motor 11 extends out of one side of the installation block 5 and is drivingly connected to a driving rod 111.

[0028] Furthermore, a clamping groove 61 corresponding to the key block 112 is opened on one side in the middle of the brush roller 6. And when the brush roller 6 is connected to the driving rod 111, the key block 112 and the clamping groove 61 are fitted and clamped, so as to ensure the transmission stability through the mutual clamping of the two.

[0029] Furthermore, a threaded hole is opened in the middle of one side of the rotating cover plate 10. And the rotating cover plate 10 is installed by being screwed on the threaded section 113 arranged on one side of the driving rod 111.

[0030] In this embodiment, the PCB board to be cleaned is placed in the cleaning tank 2 at the upper part of the machine body 1. By adjusting the positions of the corresponding locking rods 7 and locking the corresponding locking bolts 71, the locking bolts 71 are locked with the cleaning tank 2, so as to ensure that the PCB is stably locked on the cleaning tank 2 and ensure the stability of the cleaning process.

[0031] Meanwhile, the transverse movement mechanism 4 drives the mounting block 5 to move. At the same time, an external water pump and air pump assembly send cleaning liquid and high-speed gas into the spray rack 8 and the air jet rack 9 through a connecting pipe. Multiple spray nozzles are provided in the spray rack 8 to spray the cleaning liquid. At this time, the drive motor 11 inside the mounting block 5 drives the drive rod 111 to rotate, so that the brush roller 6 contacts the surface of the PCB board below, and cooperates with the cleaning liquid to achieve an efficient cleaning effect, thereby effectively removing stains, ink, etc. on the copper foil of the PCB board. Then, the air jet rack 9 on the other side sprays high-speed gas to jet the copper foil surface of the PCB board, blowing out water stains and stains.

[0032] Among them, during actual use, the spray rack 8 is connected to an external water pump through a connecting pipe, and cleaning agent is introduced, and the cleaning agent is sprayed onto the copper foil surface of the PCB board through the built-in spray nozzles.

[0033] Among them, during actual use, the air jet rack 9 is connected to an external air pump through a connecting pipe, and high-speed gas is introduced, and the high-speed gas is sprayed onto the copper foil surface of the PCB board through the built-in air jet nozzles.

[0034] Among them, during actual use, during the cleaning process of the copper foil surface of the PCB board, the spraying operation of the spray rack 8 is carried out first, then the brushing operation of the brush roller 6 is carried out, and then the air jet rack 9 jets air.

[0035] Among them, during actual use, the waste water after cleaning will fall into the cleaning tank 2 and be discharged through the waste water pipe 3.

[0036] Among them, during actual use, the rotating cover plate 10 can effectively protect the brush roller 6, prevent it from falling off, and ensure its rotational stability.

[0037] Among them, during actual use, after long-term use, stains accumulate on the surface of the brush roller 6. At this time, by rotating the rotating cover plate 10, the rotating cover plate 10 is screwed off from the threaded section 113 provided on one side of the drive rod 111 through threading. At this time, by pulling out the brush roller 6, the brush roller 6 is disengaged from the key block 112 provided on the drive rod 111, thereby completing the replacement operation of the brush roller 6.

[0038] It should be noted that the transverse movement mechanism 4 is a mechanical device used to realize the horizontal movement of an object or equipment. It is internally provided with corresponding transmission components such as a servo motor and a lead screw, and the mounting block 5 is used as its moving part to realize the transverse movement operation. The specific components and drive principles not described in detail above are all well-known common knowledge to those skilled in the art and will not be elaborated here.

[0039] In the present utility model, through the arrangement of components such as the brush roller 6, the air jet frame 9, and the spray frame 8, when cleaning the copper foil surface of the PCB board, the brush roller 6 can quickly and stably sweep and clean its surface, with high cleaning efficiency and thorough cleaning effect. At the same time, through the arrangement of components such as the rotating cover plate 10, the threaded section 113, and the key block 112, the disassembly convenience of the brush roller 6 can be effectively improved, further improving the cleaning efficiency of the device and ensuring the cleaning effect.

[0040] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, should be covered within the protection scope of the present utility model.
