Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a novel single-sided dust removal machine. Background Art

[0002] PCB is the abbreviation of printed circuit board in English. Usually, the conductive pattern made of printed circuits, printed components or a combination of the two on the insulating material according to the predetermined design is called a printed circuit. The conductive pattern that provides electrical connection between components on the insulating substrate is called a printed circuit. In this way, the finished board of printed circuits or printed circuits is called a printed circuit board, also known as a printed board or printed circuit board. Circuit boards can be divided into the following categories according to their functions: single-sided circuit boards, double-sided circuit boards, multi-layer circuit boards, aluminum-based circuit boards, impedance circuit boards, FPC flexible circuit boards, etc.

[0003] During the transportation and storage process after the production of PCB boards, dust will accumulate on their surface, which has a great impact on PCB boards. In addition, static electricity is often formed on the surface of PCB boards due to contact and friction. This static electricity attached to the surface of PCB boards will adsorb fine particles such as dust to the surface of electronic components, making it impossible to perform semiconductor processing such as lithography and etching. Static electricity discharge can also cause safety accidents. Therefore, it is often necessary to remove dust from the surface of PCB boards through dust removal equipment.

[0004] However, the existing dust removal equipment has poor dust removal effect. Most of them use water to wash and remove dust. They cannot effectively remove the dust on the PCB board, and cannot eliminate the static electricity on the PCB board, which affects the later processing effect. It has gradually failed to meet people's needs. Utility Model Content

[0034] See also Figures 1 to 6The embodiment of the utility model provides a novel single-sided dust removal machine, comprising a frame 1, and a PCB board conveying track 2, a brush dust removal mechanism 3, a feeding static removal mechanism 4, a dust sticking roller mechanism 5 and a discharging static removal mechanism 6 arranged on the frame 1. The PCB board conveying track 2 is provided with a brush dust removal station, a feeding static removal station, a roller dust removal station and a discharging static removal station in sequence along its conveying direction. The brush dust removal mechanism 3 is located above the brush dust removal station, the feeding static removal mechanism 4 is located above the feeding static removal station, the dust sticking roller mechanism 5 is located above the roller dust removal station, and the discharging static removal mechanism 6 is located above the discharging static removal station. During operation, the PCB board conveying track 2 receives the PCB board conveyed from the previous process; when the PCB board conveying track 2 conveys the PCB board to the brush dust removal station, the brush dust removal mechanism 3 performs preliminary dust removal on the upper surface of the PCB board through the brush, and collects the raised dust simultaneously; when the PCB board conveying track 2 conveys the PCB board after preliminary dust removal to the feeding anti-static mechanism 4, the feeding anti-static mechanism 4 removes the static electricity on the PCB board, so that the dust is not easy to adhere to the surface of the PCB board; when the PCB board conveying track 2 conveys the PCB board after static elimination to the roller dust removal station, the dust sticking roller mechanism 5 sticks the dust on the upper surface of the PCB board through the roller to achieve secondary dust removal; when the PCB board conveying track 2 conveys the PCB board after secondary dust removal to the discharging anti-static mechanism 6, the discharging anti-static mechanism 6 removes the static electricity on the PCB board for the second time; finally, the PCB board conveying track 2 conveys the PCB board after dust removal and anti-static removal to the next process.

[0035] The novel single-sided dust removal machine provided in the present embodiment adopts a dual dust removal design of a brush dust removal mechanism 3 and a dust sticking roller mechanism 5. The brush dust removal mechanism 3 first removes the dust preliminarily, and the dust sticking roller mechanism 5 performs secondary dust removal to ensure the cleanliness of the surface of the PCB board and to ensure that the dust on the surface of the PCB board is effectively removed; by providing an in-feed static removal mechanism 4 and a discharging static removal mechanism 6, static electricity is eliminated on the PCB board before and after dust removal, respectively, effectively preventing the influence of static electricity on the PCB board; after static electricity is eliminated, fine particles such as dust are not easy to adhere to the surface of electronic components, which is not only beneficial to the dust removal operation of the dust sticking roller mechanism 5, but also improves the effect of subsequent processing; the entire dust removal process is automatically completed through the PCB board conveying track 2 without manual intervention, thereby improving production efficiency and reducing labor costs.

[0036] See also Figure 4In one embodiment, the PCB board conveying track 2 includes a fixed rail 21 and a movable rail 22 arranged relatively to each other, and the movable rail 22 can be close to or away from the fixed rail 21. The PCB board conveying track 2 can adjust the distance between the fixed rail 21 and the movable rail 22 according to the size of the PCB board through the fixed rail 21 and the movable rail 22 arranged as above, so that the dust collector can be suitable for PCB boards of different widths. This adjustable spacing design greatly improves the compatibility and flexibility of the equipment, so that one equipment can process PCB boards of various specifications, reducing the production cost and the complexity of equipment maintenance.

[0037] See also Figure 4 In one embodiment, a conveyor belt 211 is provided on the opposite side of the fixed rail 21 and the movable rail 22. The conveyor belt 211 is connected to the belt drive motor through the transmission component 212. After the belt drive motor is started, the transmission component 212 drives the conveyor belt 211 on the fixed rail 21 and the movable rail 22 to rotate smoothly and continuously, thereby realizing efficient conveying of PCB boards through the conveyor belt 211, improving the working efficiency of the dust collector, and enabling the entire production line to complete the dust removal and static electricity removal of PCB boards more quickly. The utility model adopts the conveyor belt 211 as a conveying component because its maintenance and replacement are relatively simple and convenient; when the conveyor belt 211 is worn or fails, the operator can quickly replace or repair it, thereby ensuring the normal operation of the dust collector.

[0038] See also Figure 5 In one embodiment, the brush dust removal mechanism 3 includes a dust cover 31, a brush roller 32 and a brush drive motor 33. A dust suction port 311 is provided at the bottom of the dust cover 31. The brush roller 32 is rotatably arranged on the dust suction port 311. The bottom of the brush roller 32 is lower than the dust suction port 311. A dust suction pipe 312 for connecting a vacuum cleaner is provided at the top of the dust cover 31. The brush drive motor 33 is fixed on one side of the dust cover 31, and the drive shaft of the brush drive motor 33 is connected to one end of the brush roller 32. When the PCB board conveying track 2 conveys the PCB board to the brush dust removal station, the brush drive motor 33 is started to drive the brush roller 32 to rotate continuously. Since the brush roller 32 is in direct contact with the upper surface of the PCB board, the dust on the surface of the PCB board can be effectively removed through continuous rotation. The fine structure and material selection of the brush on the brush roller 32 enable it to clean deeply without leaving dead corners, thereby ensuring the cleanliness of the surface of the PCB board. In addition, since the brush dust removal mechanism 3 integrates the dust hood 31 and the dust suction pipe 312, the vacuum cleaner can suck the dust raised by the brush roller 32 through the dust suction pipe 312 while the brush roller 32 is being cleaned, thereby preventing the dust from scattering and keeping the working environment clean.

[0039] See also Figure 5In one embodiment, the brush dust removal mechanism 3 further includes a lifting cylinder 34, which is fixed vertically downward on the frame 1, and the telescopic end of the lifting cylinder 34 is connected to the top of the dust cover 31. The addition of the lifting cylinder 34 allows the height of the brush roller 32 to be flexibly adjusted. This means that no matter how the thickness of the PCB board changes, the telescopic end of the lifting cylinder 34 can be adjusted to ensure that the brush roller 32 and the surface of the PCB board maintain an appropriate contact pressure, which can not only improve the dust removal effect, but also prevent the brush roller 32 from causing excessive wear on the surface of the PCB board. By adjusting the height of the brush roller 32, it can adapt to PCB boards of different specifications, ensuring that each board can obtain the best dust removal effect. In addition, the automatic control of the lifting cylinder 34 makes it unnecessary for the operator to manually adjust the height of the brush roller 32, which simplifies the operation process and improves work efficiency.

[0040] See also Figure 5 In one embodiment, the brush drive motor 33 is connected to one end of the brush roller 32 through a gear transmission member 35. The gear transmission member 35 can accurately transmit the rotational power of the brush drive motor 33 to the brush roller 32 through the meshing between the gears, thereby reducing energy loss during the transmission process and improving transmission efficiency. The gear transmission member 35 has a relatively simple structure and is relatively easy to disassemble and install; when replacement or maintenance is required, the operator can quickly operate, reducing the difficulty and cost of maintenance.

[0041] See also Figure 3 , Figure 6 In one embodiment, the dust sticking roller mechanism 5 includes a fixed frame 51, a dust removal roller 52, a dust sticking roller 53 and a dust removal motor. The dust removal roller 52 and the dust sticking roller 53 are rotatably arranged at the lower end of the fixed frame 51. The dust sticking roller 53 is located above the dust removal roller 52 and contacts with the dust removal roller 52. The dust removal motor is fixed on one side of the fixed frame 51, and the driving shaft of the dust removal motor is connected to one end of the dust sticking roller 53 to drive the dust sticking roller 53 to rotate continuously. When the PCB board conveying track 2 conveys the PCB board to the roller dust removal station, the dust removal roller 52 contacts the upper surface of the PCB board, and the dust collecting roller 53 will pick up the dust on the upper surface of the PCB board when it rotates. At the same time, since there is a dust collecting roller 53 above the dust removal roller 52 that is in contact with the dust removal roller 52 at all times, the dust removal roller 52 picks up the dust on the upper surface of the PCB board while transferring the dust to the sticky paper of the dust collecting roller 53 through contact with the dust collecting roller 53, so as to ensure that the dust removal roller 52 is clean and can be cleaned normally when it contacts the PCB.

[0042] It should be noted that, in the present embodiment, the dust removal roller 52 is a silicone roller, the surface of which is sticky and can remove dust on the upper surface of the PCB board after contacting the upper surface of the PCB board. In addition, preferably, two dust removal rollers 52 are provided, and the two dust removal rollers 52 are arranged side by side below the dust collection roller 53 and contact the dust collection roller 53. The presence of two dust removal rollers 52 means that there are two cleaning opportunities for the surface of the PCB board, which helps to remove dust particles that may stubbornly adhere to the board surface, further improve the cleaning effect, and ensure the cleanliness of the surface of the PCB board. At the same time, when the efficiency of one dust removal roller 52 may be reduced due to being full of dust during the cleaning process, the other dust removal roller 52 is still working normally, which can ensure the continuity of the cleaning work and avoid production interruption caused by the performance degradation of a single dust removal roller 52.

[0043] See also Figure 6 In one embodiment, slide rails 54 are provided on both sides of the top of the fixed frame 51, and the fixed frame 51 is slidably arranged in the frame 1 through the slide rails 54. A pull plate 55 is provided on one side of the fixed frame 51, and an opening for the fixed frame 51 to slide out is provided on one side of the fixed frame 51 corresponding to the pull plate 55, and the two ends of the dust-collecting roller 53 are detachably connected to the fixed frame 51. After the dust-collecting roller mechanism 5 has been used for dust removal for a period of time, it is necessary to pull out the entire dust-collecting roller mechanism 5 through the pull plate 55, tear off the used dust-collecting paper on the surface of the dust-collecting roller 53, and let the next layer of clean dust-collecting paper continue the next dust-collecting operation, thereby ensuring the dust-collecting effect of the entire dust-collecting roller mechanism 5. In addition, since the two ends of the dust-collecting roller 53 are detachably connected to the fixed frame 51, when the dust-collecting paper on the dust-collecting roller 53 is completely used up, it is convenient to remove the dust-collecting roller 53 and install new dust-collecting paper.

[0044] See also Figure 2 , Figure 3 In one embodiment, both the feed static electricity removal mechanism 4 and the discharge static electricity removal mechanism 6 are ion wind rods, and the air outlet of the ion wind rods faces the PCB board conveying track 2. The ion wind rods blow ion wind toward the upper surface of the PCB board below them to eliminate static electricity on the PCB board, so that dust is not easy to adhere to the surface of the PCB board.

[0045] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0046] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
