Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 and 2, fig. 1 is a view from a certain perspective of a dry cleaning apparatus according to a first embodiment of the present invention; fig. 2 is a schematic structural view of a dust removing mechanism in the first embodiment of the present invention.
In this embodiment, a dry cleaning apparatus is provided, including: the dust removing device is provided with a transmission mechanism 200 and a dust removing mechanism 100 which is arranged close to the transmission mechanism 200;
the transmission mechanism 200 is used for transmitting the target object;
the dust removing mechanism 100 is configured to output a high-pressure airflow to the target object and clean dust of the target object.
According to the invention, the target object is continuously subjected to a pulling force through the transmission mechanism 200, and when the dust removal mechanism 100 is used for emitting high-pressure airflow to wash the target object, the airflow exerts another force on the target object; the dust on the target object is comprehensively and efficiently clear under the action of two forces. The invention has the advantages that the transmission mechanism 200 and the high-pressure airflow are used to replace the traditional washing mechanism, not only the omnibearing dust removal is provided, but also the possibility of oxidation is avoided, the dust removal effect is enhanced, and the defect of the traditional method for dust removal is overcome. Wherein the target object may be a PCB board of a minute size. The PCB with the small size can be a PCB in a mobile phone of each brand, a PCB in an intelligent watch of each brand, or any other PCB with the small size.
Specifically, the dust removing mechanism 100 includes a high-pressure airflow nozzle 110 and a dust removing brush 120 attached to the high-pressure airflow nozzle 110; the high-pressure air flow nozzle 110 is configured to output a high-pressure air flow to the target object; the dust cleaning brush 120 is configured to clean dust from the target object.
In this embodiment, the dust cleaning brush 120 is disposed around the high-pressure air flow nozzle 110 while using the high-pressure air flow output from the high-pressure air flow nozzle 110. Based on this, the operation flow of the dust removing mechanism 100 is as follows: firstly, the dust cleaning brush 120 at one side of the nozzle 110 will clean the dust first; then, the target object is flushed by the high-pressure airflow, and meanwhile, the dust cleaning brush 120 close to the nozzle 110 removes dust; finally, the dust on the other side of the nozzle 110 is cleaned again. Therefore, before, during and after the high-pressure airflow of the dust removing mechanism 100 washes, the dust cleaning brush 120 is used to treat the dust of the target object, and finally, a better cleaning effect is achieved. The number of the high-pressure gas flow nozzle 110 and the dust cleaning brush 120 may be one, two or more. The target object is a PCB or a jig of the PCB.
In a further embodiment, the pair of high-pressure air nozzles 110 output high-pressure air relatively, and the pair of dust brushes 120 abut. The advantages of the scheme in this embodiment are as follows: firstly, the oppositely arranged dust removal mechanisms 100 can simultaneously carry out dust removal treatment on the front surface and the back surface of the PCB; secondly, the dust removing brushes 120 in pairs are abutted to apply forces with opposite directions and similar magnitudes to the PCB, the displacement trend of the PCB is moderate, the texture of the dust removing brushes 120 is relatively soft, and even if the PCB collides with a jig, the PCB is not easy to damage under the condition that the dust removing brushes 120 are abutted.
Please refer to fig. 3, 4, and 5; FIG. 3 is a schematic view of a second embodiment of a dust raising mechanism according to the present invention; fig. 4 is a view from a certain perspective of a dry cleaning apparatus according to a second embodiment of the present invention; fig. 5 is a schematic view of the arrangement of the dust raising mechanism in the second embodiment of the present invention. In this embodiment, the dry cleaning apparatus further includes at least one dust raising mechanism 300 disposed near the transmission mechanism 200, the dust raising mechanism 300 includes a first fan 310 and a second fan 320 which are disposed in a staggered manner, the first fan 310 is disposed above the transmission mechanism 200, the second fan 320 is disposed below the transmission mechanism 200, and the dust raising mechanism 300 is configured to output an airflow to the target object to remove dust from the target object.
In this embodiment, the first fan 310 and the second fan 320 are disposed in a staggered manner, so that wind power in two directions can be provided without conflict, and dust on two sides of the PCB is lifted. It should be appreciated that, when the dust brush 120 is used to remove dust from the PCB, floating dust may remain on the PCB, and the floating dust is removed by using wind in two directions. In the process of removing the floating dust, the excessive wind force is not needed, and only a large area of wind is needed, so the floating dust can be smoothly removed by using the first fan 310 and the second fan 320. In addition, the first fan 310 and the second fan 320 may be one fan or a combination of a plurality of fans; the plurality of fans may be arranged in a matrix or may be arranged arbitrarily.
Further, the number of the dust removing mechanisms 100 is several, and at least one dust raising mechanism 300 is arranged between every two adjacent dust removing mechanisms 100. The use of a plurality of dust removal mechanisms 100 can improve the dust removal effect, but the dust removal mechanisms 100 can generate repeated work due to the fact that floating dust is not blown in time, and therefore the work efficiency is reduced. Therefore, at least one dust raising mechanism 300 is arranged between the adjacent dust removing mechanisms 100, so that the dust removing effect is improved.
Referring to fig. 6 and 7, fig. 6 is a plan view showing an overall structure of a dry cleaning apparatus according to a third embodiment of the present invention; fig. 7 is a schematic view of a vacuum dust collecting pipe according to a third embodiment of the present invention.
In this embodiment, the dry cleaning apparatus further includes: the vacuum dust collecting pipe 420 and at least one external connection pipe 410 connected to the vacuum dust collecting pipe 420, wherein the vacuum dust collecting pipe 420 is arranged along the transmission mechanism 200 and is used for absorbing dust; the extension tube 410 is connected to a vacuum pipe 420 for transporting dust to be carried away. In this embodiment, the vacuum tube is closed. When the dust raising mechanism 300 blows the dust on the PCB, the vacuum dust collecting pipe 410 absorbs the dust, and the external pipe 420 sucks away and transmits the dust. Therefore, dust can be collected in time, and the blown floating dust is prevented from falling onto the PCB.
Specifically, the number of the dust removing mechanisms 100 is four. In general knowledge, the more the dust removing mechanism 100 is used, the more excellent dust removing effect can be obtained. However, in the present embodiment, four dust removing mechanisms 100 are provided, so that a superior dust removing effect can be ensured. Therefore, the space, the time and the cost can be saved.
Further, the dry cleaning device further comprises dust cleaning brushes 120 close to the input end of the transmission mechanism 200, the dust cleaning brushes 120 are arranged in pairs, and the pairs of dust cleaning brushes 120 are oppositely arranged and abutted. The dust cleaning brush 120 is disposed near the input end of the driving mechanism 200, and the high pressure air flow nozzle 110 is not disposed, mainly because the PCB board at this position has excessive floating dust, and this position is communicated with the outside, and therefore, the dust may be diffused to the outside environment. Secondly, because the PCB board at this moment has more dust, do not use the high-pressure draught, can get rid of more dust too.
Further, at least one dust raising mechanism 300 is arranged between the dust cleaning brush 120 close to the input end of the transmission mechanism 200 and the dust removing mechanism 100. Thereby, a certain amount of fly ash can be removed.
The dust brush 120 is a bristle brush. Therefore, dust can be removed better, and the PCB can be prevented from being damaged. It should be understood that the traditional dust removing brush is a woolen brush, while the bristle brush has relatively soft texture and unchanged dust removing effect.
Further, the transmission mechanism 200 is a linear transmission mechanism 200, and thus, other mechanisms can be more conveniently provided. Based on this, the above-mentioned dust removing brush and the nozzle 110 are respectively installed on the plurality of first sidewalls, and the plurality of parallel first sidewalls are distributed along the linear transmission mechanism 200 and perpendicular to the linear transmission mechanism 200. The first side wall is arranged in the closed shell. The closed shells can be in the shape of a cuboid or a cube, and all parts of the shells and the first side wall are detachable.
In a further embodiment, the dry cleaning apparatus of any of the above embodiments further includes a dry cleaning fixture detachably connected to the transmission mechanism 200, and the dust removing fixture includes a bottom plate and a pressing plate, the bottom plate and the pressing plate are both provided with an accommodating structure, the bottom plate is provided with at least one first air flow channel, the pressing plate is provided with at least one second air flow channel, the first air flow channel and the second air flow channel are arranged opposite to each other, and the accommodating structure is close to the first air flow channel and the second air flow channel; wherein, the accommodating structure is used for placing the PCB.
In the embodiment, the first airflow channel and the second airflow channel are oppositely arranged, so that convenience is provided for the circulation of air, and the air flow rate is ensured; the PCB is arranged in the containing structure close to the two airflow channels, and dust on the PCB is easily impacted by larger air flow and is also easily dispersed from the airflow channels. In addition, the jig mode using the bottom plate and the pressing plate is more easily matched with the linear transmission mechanism 200.
Specifically, the PCB board is a tiny board, and the thickness of the accommodating structure is 0.5mm thicker than the tiny board. The accommodating structure not only can generate redundant space, but also can ensure that the PCB is stably fixed in the accommodating structure, thereby better cleaning the PCB.
In a further embodiment, the dry cleaning apparatus of any of the above embodiments further includes a PCB loading mechanism and a displacement mechanism of the output end, thereby implementing full-automatic dry cleaning of the PCB.
