Technical Field

[0002] PCB is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. PCB has developed from single-layer to double-sided, multi-layer and flexible, and still maintains its own development trend, constantly developing towards high precision, high density and high reliability.

[0003] In the production process of PCB boards, almost every process will cause a certain degree of pollution to the PCB boards. For example, the SMT stage will cause oxidation of the PCB boards and electronic components, the welding stage will cause pollution from operator fingerprints or flux residues, and the repair stage will cause pollution from dust or tin ash. The presence of these pollutants will not only affect the appearance of the PCB boards, but also have a negative impact on the performance of the PCB boards. Therefore, cleaning of the PCB boards is very important.

[0004] However, some existing cleaning devices for PCB boards do not clean thoroughly, resulting in unsatisfactory cleaning effects.

[0005] Therefore, a PCB cleaning device capable of flipping and cleaning is proposed. Utility Model Content

[0023] See also Figure 1 and Figure 2 , the utility model provides a technical solution:

[0024] A PCB cleaning device capable of flipping for cleaning comprises a support frame 101, on which a cleaning mechanism for cleaning a PCB 201 and a plurality of flipping mechanisms arranged at intervals are arranged, and the execution end of any flipping mechanism is detachably connected to the PCB 201; during cleaning, the flipping mechanism puts the PCB 201 in a flipped state.

[0025] In some implementations of this embodiment, the cleaning mechanism includes a plurality of cleaning tubes 301 spaced apart on the support frame 101, and any cleaning tube 301 is connected to a plurality of water nozzles 302; during cleaning, the PCB board 201 is located between two adjacent cleaning tubes 301, and the water spraying direction of the water nozzles 302 is toward the PCB board 201.

[0026] In some implementations of this embodiment, any flipping mechanism includes a base 401 connected to the support frame 101, a reciprocating mechanism and a flipping unit, the reciprocating mechanism includes a slider 402 slidably connected to the base 401 and a screw nut mechanism 403 connected to the support frame 101, the nut of the screw nut mechanism 403 is connected to the slider 402, and the central axis of the screw of the screw nut mechanism 403 is parallel to the sliding direction of the slider 402; the flipping unit is connected to the slider 402, and the PCB board 201 is detachably connected to the execution end of the flipping unit. In this embodiment, the actions of all screw nut mechanisms 403 can be controlled by the same control device. This control method is a prior art and will not be described in detail here. In other implementations of this embodiment, the screw nut mechanism 403 can also be replaced by a hydraulic rod or other mechanism.

[0027] In some implementations of this embodiment, the flip unit includes a rotating shaft 404, and a gear 405 and a rack 406 that mesh with each other, the rack 406 is arranged on the base 401, and the extension direction of the rack 406 is the same as the sliding direction of the slider 402; the rotating shaft 404 passes through the slider 402 and is rotatably connected to the slider 402, and the central axis of the rotating shaft 404 is perpendicular to the sliding direction of the slider 402; one end of the rotating shaft 404 is detachably connected to the PCB board 201, and the other end is connected to the gear 405.

[0028] In order to facilitate temporary fixing of the PCB board 201 on one end of the rotating shaft 404, a fixing clip is installed at the end of the rotating shaft 404 away from the gear 405 (since the fixing clip is a prior art, its specific structure is not shown in the drawings of this embodiment). After cleaning, it is convenient to remove the PCB board 201. In other implementations of this embodiment, a groove can be designed at one end of the rotating shaft 404 where the PCB board 201 is installed. During installation, the PCB board 201 is first placed in the groove, and then the PCB board 201 is fixed in the groove using fasteners such as bolts, so that the PCB board 201 can also be temporarily fixed on the rotating shaft 404.

[0030] In order to facilitate the movement of the device, a plurality of running wheels 601 are installed at the bottom of the support frame 101 .

[0031] Working principle:

[0032] When the PCB board 201 needs to be cleaned, several PCB boards 201 are first installed on the respective rotating shafts 404, and then the cleaning is performed. During the cleaning process, each screw nut mechanism 403 can be controlled to work by a matching control device, so that the slider 402 can reciprocate on the base 401 under the control of the screw nut mechanism 403. During the reciprocating movement of the slider 402, due to the existence of the gear 405 and the rack 406, the rotating shaft 404 will rotate with the movement of the slider 402, thereby driving the PCB board 201 to rotate, so that the cleaning liquid sprayed by the water nozzle 302 can cover all places on the surface of the PCB board 201, thereby improving the cleaning effect. After the sprayed cleaning liquid cleans the PCB board 201, it can flow to the liquid collecting tank 501 below.
