Description

Technical Field

[0001] This utility model relates to a cleaning device suitable for PCB boards. Background Technology

[0002] Printed circuit boards (PCBs) are substrates used for assembling electronic components. They are printed boards with interconnections and components formed on a general-purpose substrate according to a predetermined design. The main function of a PCB is to connect various electronic components into predetermined circuits, acting as a relay for transmission. It is a key electronic interconnect component in electronic products and is known as the "mother of electronic products." High-density PCBs (HDI) are experiencing continuous growth due to the rapid development of the artificial intelligence industry and increased investment in computing power in China.

[0003] A search revealed a patent: an etching device (CN202321786433.5), comprising a conveying mechanism, a first spraying mechanism, a second spraying mechanism, a suction mechanism, and a blowing mechanism. The first spraying mechanism and the suction mechanism are both positioned above the conveying mechanism, and are offset from each other along the conveying direction. The first spraying mechanism sprays etchant onto the upper surface of the object to be etched, and the suction mechanism absorbs the etchant from the upper surface. The second spraying mechanism and the blowing mechanism are both positioned below the conveying mechanism, and are offset from each other along the conveying direction. The second spraying mechanism sprays etchant onto the lower surface of the object to be etched, and the blowing mechanism blows air onto the lower surface. The spraying effect of the aforementioned components is unsatisfactory and cannot fully cover the product.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of cleaning device suitable for PCB boards, making it more valuable for industrial applications. Utility Model Content

[0022] Example

[0023] like Figure 1 and Figure 2 As shown, a cleaning device suitable for PCB boards includes a frame 1, a transmission component 2 connected to the frame 1, a first spray component 3 and a second spray component 4 of the same structure connected between the transmission components 2, and a cleaning component 5 connected between the first spray component 3 and the second spray component 4.

[0024] The cleaning assembly 5 includes an upper cleaning assembly 51 and a lower cleaning assembly 52 with the same structure, which are arranged vertically opposite each other. The upper cleaning assembly 51 includes a cleaning shaft 53. An adjustment groove 54 is provided on the frame 1. An adjustment block 55 is connected in the adjustment groove 54. The cleaning shaft 53 is connected between the adjustment blocks 55. A cleaning sleeve 56 is fitted on the cleaning shaft 53. A cleaning brush 57 is connected to the cleaning sleeve 56. A drive bracket 58 is connected to the side of the frame 1. A drive shaft 59 is connected between the drive brackets 58. A drive motor 510 is connected to the drive bracket 58. The drive shaft of the drive motor 510 is connected to one end of the drive shaft 59. Several active bevel gears 511 are connected to the drive shaft 59 and are synchronously connected to it. A driven bevel gear 512 is connected to one end of the cleaning shaft opposite to the drive shaft. The driven bevel gear 512 meshes with its corresponding active bevel gear 511.

[0025] In this invention, an adjusting rod 513 for adjusting the height of the adjusting block 55 is threaded through the frame 1. A slide rail is connected to the side of the adjusting groove 54, and a sliding groove is provided on the adjusting block to slide along the slide rail. The adjusting rod can be used to adjust the height of the adjusting block, thereby improving the fit of the brush to the product and enhancing its cleaning effectiveness.

[0026] In this utility model, the first spray assembly 3 includes a spray pipe 31, which is connected to the frame 1 via a spray connecting block. One end of the spray pipe 31 is connected to a water pump via an external pipe, and a plurality of spaced spray heads 32 are connected to the spray pipe 31.

[0027] The transmission component 2 described in this invention is a transmission roller driven by a motor and gears.

[0028] The working principle of this utility model is as follows:

[0029] In practice, the product is transported via a transmission assembly. During the transmission process, the product first reaches the first spray assembly, where sensors transmit information to the control device (PLC). The control device then controls the water pump to spray the product. As the product moves forward, it reaches the cleaning assembly, where the control device drives the drive motor, which in turn rotates the cleaning shaft to clean both the top and bottom surfaces of the product. After cleaning, the product reaches the second spray assembly for another round of spraying and cleaning. After multiple cycles of this process, the product is finally conveyed through the transmission assembly and exits from the discharge port.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
