Description

Technical Field

[0001] The present invention relates to the technical field of flexible circuit board cleaning and dust removal equipment, and in particular to an anti-static vacuum dust removal equipment for cleaning a flexible circuit board jig. Background Art

[0002] In the manufacturing process of flexible printed circuits (FPCs), cleaning the surface of the FPC jig is a critical step in ensuring product quality. As electronic components become increasingly miniaturized and sophisticated, tiny foreign matter such as dust and metal debris easily adhere to the surface of the FPC jig. If not promptly removed, this not only affects the accuracy of subsequent pressing and welding processes, but can also cause circuit shorts or performance failures. Traditional dust removal methods often use a single brush or simple vacuum suction devices. These devices generally suffer from a single dust removal path and uneven suction distribution, making them difficult to meet the cleaning needs of high-precision FPCs.

[0003] Some existing dust removal equipment lacks anti-static design, and static electricity generated during the cleaning process can easily damage the insulation layer or conductive lines of flexible circuit boards. Furthermore, the traditional separate brush and vacuum suction mechanism cannot achieve the coordinated "dust removal and foreign matter absorption" operation, resulting in low dust removal efficiency and the risk of secondary contamination. This is especially true for flexible circuit board jigs with complex surface structures, as traditional equipment struggles to reach corners and grooves, creating blind spots.

[0004] Furthermore, existing dust removal equipment often utilizes a single motor drive system, lacking precise control over the brush's rotation direction and trajectory, making it impossible to adjust cleaning strategies based on dust distribution characteristics. Furthermore, vacuum systems lack systematic calculations of suction port size and airflow distribution, resulting in insufficient suction force and wasted energy, making it difficult to adapt to the cleaning needs of varying batches of flexible plate jigs. Therefore, an integrated device combining efficient dust removal, anti-static performance, and automated control is urgently needed to address these shortcomings of existing technologies. Summary of the Invention

[0005] The main purpose of the present invention is to provide an anti-static vacuum dust removal device for cleaning flexible plate jigs, aiming to solve the problems of low dust removal efficiency and poor anti-static effect.

[0006] To achieve the above-mentioned object, the present invention proposes an anti-static vacuum dust removal device for cleaning a flexible plate jig, comprising a cleaning brush vacuum dust removal mechanism for cleaning the surface of the flexible plate jig;

[0007] The cleaning brush vacuum dust removal mechanism comprises:

[0008] Two anti-static strip brushes are scientifically arranged to cover a large area of ​​the flexographic jig surface. They are at a micro distance from the flexographic jig, effectively blocking the production and forming a vacuum adsorption isolation zone.

[0009] The anti-static roller brush, with its unique roller shape, can penetrate into the tiny gaps of the flexible plate jig when rotating, effectively lifting hidden dust;

[0010] A follower fixed seat, the transmission shaft of the anti-static roller brush is coaxially engaged with the follower fixed seat;

[0011] A vacuum cleaning frame, which is composed of a U-shaped frame and a duct, wherein the U-shaped frame and the duct are interconnected, the U-shaped frame is used to form a vacuum suction port channel, and the duct transports dust to a subsequent processing device, forming an efficient dust transmission channel;

[0012] Two sealing plates are fixedly mounted at the two end openings of the U-shaped frame along its length direction. Two anti-static strip brushes are fixedly mounted on the outer surfaces of the two side walls of the U-shaped frame. The side surface of one of the sealing plates is tightly fitted with the follower fixing seat to enhance the overall stability of the mechanism. The transmission shaft of the anti-static roller brush passes through the sealing plate and is coaxially engaged with the follower fixing seat to ensure accurate transmission of rotational power.

[0013] A guide plate is disposed within the U-shaped frame, with both sides of its long sides fixedly connected to the two side walls of the U-shaped frame, and a space is formed between the lower surface of the guide plate and the bottom plate of the U-shaped frame. The guide plates are provided with a plurality of guide holes, which are precisely designed and calculated to have a diameter and distribution density that are highly compatible with the dust collection performance of the equipment, thereby efficiently guiding dust.

[0014] The inner guide cover has a U-shaped structure, with its opening aligned with the U-shaped frame. Its bottom plate is fixed to the side of the guide plate away from the bottom plate of the U-shaped frame, with a space formed between the two side walls and the two side walls of the U-shaped frame. A U-shaped space is formed between the U-shaped frame and the inner guide cover, with two vacuum suction ports formed on both sides of the opening to quickly suck in raised dust and debris and pass them through the guide holes into the duct.

[0015] A top cover plate, which is fixedly mounted on the outer surface of the bottom plate of the U-shaped frame to facilitate subsequent quick disassembly and maintenance;

[0016] Among them, a number of guide holes are provided on the guide plate, and a U-shaped partition space is formed between the U-shaped frame and the guide inner cover. Two vacuum suction ports are formed on both sides of the opening direction of the U-shaped partition space. The dust and debris sucked in by the vacuum suction port can pass through the guide holes and enter the duct.

[0017] Preferably, the anti-static vacuum dust removal equipment for cleaning the flexible plate jig also includes a cleaning brush drive mechanism, and the cleaning brush vacuum dust removal mechanism also includes a gear transmission mechanism, and the gear transmission mechanism is arranged on the side of the U-shaped frame away from the U-shaped frame, and the transmission shaft of the gear transmission mechanism is coaxially combined with the anti-static roller brush, and the gear transmission mechanism is meshed and connected with the cleaning brush drive mechanism, and the cleaning brush drive mechanism can drive the anti-static roller brush to rotate clockwise or counterclockwise to meet the needs of various cleaning scenarios.

[0018] Preferably, the gear transmission mechanism includes a mounting base, one end of the mounting base is fixedly connected to the sealing plate away from the follower fixing seat to form a fixed connection with the vacuum cleaning frame, and the other end of the mounting base is fixedly connected to the cleaning brush driving mechanism.

[0019] Preferably, the gear transmission mechanism also includes a gear set, which is installed on the mounting base and undergoes high-precision processing and strict quality inspection to ensure accurate and stable transmission; the cleaning brush vacuum dust removal mechanism is meshed and connected with the cleaning brush drive mechanism through the gear set to achieve efficient power transmission.

[0020] Preferably, the cleaning brush driving mechanism further comprises a round rack, which is engaged with the gear set, and the linear motion is converted into rotational motion through the transmission of the rack and the gear, thereby providing power for the anti-static roller brush.

[0021] Preferably, the cleaning brush driving mechanism also includes a rodless cylinder, the linear guide rail of the rodless cylinder is arranged parallel to the circular rack, and the bottom of the slider of the rodless cylinder is fixedly connected to the mounting base, so that the slider of the rodless cylinder can drive the cleaning brush vacuum dust removal mechanism to slide. When the rodless cylinder is working, the slider drives the cleaning brush vacuum dust removal mechanism to reciprocate relative to the linear guide rail to achieve surface cleaning of the flexible plate jig.

[0022] Preferably, the cleaning brush drive mechanism further comprises a linear slide rail, and the slider of the rodless cylinder can slide back and forth on the linear slide rail, providing a stable motion track for the slider of the rodless cylinder, thereby ensuring the straightness and stability of the slider during sliding.

[0023] Preferably, the cleaning brush drive mechanism also includes two limit sensors, which are respectively installed on the two end portions of the same side of the linear slide rail, and use precise sensing technology to monitor the position of the rodless cylinder slider in real time; when the slider moves to the two ends of the flexible plate jig, it automatically triggers a signal to control the reversing of the rodless cylinder, thereby realizing precise reciprocating motion of the cleaning mechanism.

[0024] Preferably, the bristles of the antistatic strip brush and the antistatic roller brush are made of bristles, and the bristles are treated with antistatic treatment, and the surface resistance value is within 10 6 Ω to 10 9 The material is both flexible and wear-resistant, and will not damage the surface of the flexible board fixture during cleaning. It also effectively suppresses static electricity generation and protects the conductive circuit and insulation layer of the fixture.

[0025] Preferably, the anti-static vacuum dust removal equipment for cleaning the flexible plate jig also includes a pneumatic vacuum dust collector, the suction port of the pneumatic vacuum dust collector is connected to the duct, and the cross-sectional area of ​​the suction port of the pneumatic vacuum dust collector is greater than or equal to the cross-sectional area of ​​the vacuum suction port of the cleaning brush vacuum dust removal mechanism; this design ensures that the pneumatic vacuum dust collector provides sufficient suction force to quickly collect dust and debris sucked in by the cleaning brush vacuum dust removal mechanism, and cooperates with the guide inner cover structure to prevent secondary deposition of dust and improve cleaning reliability and efficiency.

[0026] The beneficial effects of the technical solution of the present invention are:

[0027] 1. Efficient Dust Removal and Dynamic Collaborative Cleaning: A rodless cylinder drives the cleaning brush vacuum mechanism, creating a forward and reverse motion for the anti-static roller brush. As the cleaning brush vacuum mechanism moves back and forth, the brush rotates clockwise or counterclockwise, lifting dust and directing it into the vacuum suction port. This reciprocating motion improves dust removal efficiency. Compared to traditional single-directional cleaning, it provides full coverage of the flexible plate fixture surface, effectively removing dust and foreign matter.

[0028] 2. The anti-static protection and precise adsorption of the flexible plate fixture, the anti-static strip brush and roller brush are made of bristle material, and the surface resistance value is controlled at 10 6 Ω to 10 9 Within the Ω range, static electricity can prevent damage to the conductive circuits or insulation layers on the surface of the flexible board jig during cleaning. By precisely calculating the opening size and cross-sectional area, the guide plate evenly distributes the vacuum suction force across the entire surface of the jig, ensuring that the suction force covers the clamping area and edges of the flexible board jig, eliminating the cleaning blind spots caused by uneven suction in traditional equipment.

[0029] 3. Precise control of automated cleaning of flexible plate jigs. Linear guides and limit sensors form a closed-loop control system. The rodless cylinder's slider automatically triggers reversal when it reaches either end of the flexible plate jig, ensuring precise reciprocating motion of the cleaning mechanism along the length of the jig, preventing excessive wear on the jig surface. The pneumatic vacuum dust collector's suction port cross-sectional area is designed to be no smaller than the vacuum suction port cross-sectional area of ​​the cleaning brush vacuum mechanism. Combined with the structural design of the inner guide hood, this quickly directs raised dust into the adsorption zone, preventing secondary dust deposition on the jig surface and improving cleaning reliability.

[0039] Please refer to Figures 1 to 5 In this embodiment, an anti-static vacuum dust removal device for cleaning a flexible plate jig is proposed, including a cleaning brush vacuum dust removal mechanism 100, a cleaning brush driving mechanism 200, a pneumatic vacuum dust collector 300, a synchronous belt conveyor line mechanism 400, a flexible plate jig 500, a synchronous belt conveyor line automatic width adjustment mechanism 600, and a single-side pressing mechanism 700, which is used for cleaning the surface of the flexible plate jig.

[0040] In this embodiment, Figure 1 This is an exploded view of the cleaning brush vacuum dust removal mechanism 100. In this embodiment, the cleaning brush vacuum dust removal mechanism 100 includes two anti-static strip brushes 101, an anti-static roller brush 102, a follower fixed seat 103, a vacuum cleaning frame 104, two sealing plates 105, a guide plate 106, a guide inner cover 107, and a top cover 108.

[0041] In this embodiment, the vacuum cleaner frame 104 consists of a U-shaped frame and a duct 1042. The U-shaped frame 1041 is composed of two side panels and a bottom panel. The bottom panel has a window 1043 designed for subsequent maintenance. The U-shaped frame and duct 1042 are interconnected, forming a vacuum port 111. The duct 1042 transports dust to subsequent processing equipment, creating an efficient dust transmission channel. Two sealing plates 105 are fixedly mounted at the openings at each end of the U-shaped frame along its length. Two anti-static strip brushes 101 are fixedly mounted on the outer surfaces of the two side walls of the U-shaped frame. One of the sealing plates 105 is tightly fitted to the follower mount 103, enhancing the overall stability of the mechanism. The structural order of the fixings along the length of the U-shaped frame 1041 is: follower mount 103, one sealing plate 105, U-shaped frame 1041, and the other sealing plate 105. The drive shaft of the anti-static roller brush 102 passes through the sealing plate 105 and is coaxially connected to the follower fixed seat 103 to ensure accurate transmission of rotational power. The guide plate 106 is set in the U-shaped frame, and its two sides of the long side are fixedly connected to the two side walls of the U-shaped frame. A space is formed between the lower surface of the guide plate 106 and the bottom plate of the U-shaped frame. This space is connected to the duct 1042; the several guide holes 1061 distributed on the guide plate 106 are precisely calculated and designed. Their aperture and distribution density are highly compatible with the dust collection performance of the equipment, which can effectively guide dust. Please refer to Figure 2The inner guide cover 107 has a U-shaped structure, with its opening oriented in the same direction as the U-shaped frame. Its bottom plate is fixed to the side of the guide plate 106 away from the bottom plate of the U-shaped frame, and a space is formed between the two side walls of the U-shaped frame. In layman's terms, the U-shaped frame 1041 is a large-scale U-shape, while the inner guide cover 107 is a small-scale U-shape. The inner guide cover 107 is fixed to the U-shaped frame 1041 via the guide plate 106, thus forming a U-shaped space between the U-shaped frame and the inner guide cover 107. Two vacuum suction ports 111 are formed on either side of the opening to quickly suck in raised dust and debris, passing them through the guide holes 1061 and into the duct 1042.

[0042] In this embodiment, the top cover 108 is fixedly mounted on the outer surface of the bottom plate of the U-shaped frame to close the window opened on the bottom plate. The connection between the top cover 108 and the bottom plate is anti-deflation treated and quick-release installed to facilitate subsequent quick-disassembly and maintenance.

[0043] Please refer to Figure 1 In this embodiment, the cleaning brush vacuum dust removal mechanism 100 also includes a gear transmission mechanism 112 and a reinforcement plate 109. The gear transmission mechanism 112 is located on the side of the U-shaped frame away from the U-shaped frame. The gear transmission mechanism 112 includes a mounting base 1121. One end of the mounting base 1121 is fixedly connected to the sealing plate 105 away from the follower fixing base 103, thereby forming a fixed connection with the vacuum frame 104. The reinforcement plate 109 is mounted on the outer surface of the U-shaped frame 1041. The reinforcement plate 109 is fixedly connected to the follower fixing base 103, the two sealing plates 105, the U-shaped frame 1041, and the mounting base 1121, thereby strengthening the stability of these structures. The other end of the mounting base 1121 is fixedly connected to the cleaning brush drive mechanism 200. The gear transmission mechanism 112 also includes a gear set 1122, which is mounted on the mounting base 1121. The gear set 1122 undergoes high-precision machining and strict quality inspection to ensure accurate and stable transmission. The transmission shaft of the gear set 1122 is coaxially coupled to the anti-static roller brush 102 , and the cleaning brush vacuum dust removal mechanism 100 is meshedly connected with the cleaning brush driving mechanism 200 via the gear set 1122 , thereby achieving efficient power transmission.

[0044] Please refer to Figure 3 and Figure 4 In this embodiment, the gear transmission structure further includes a protective cover 1123, which is fixedly engaged with the mounting base 1121 and can cover the gear set 1122 to provide protection.

[0045] Please refer to Figure 3 、 Figure 4 、 Figure 5In this embodiment, the cleaning brush drive mechanism 200 includes a circular rack 201, which meshes with a gear set 1122. Through the transmission of the rack and gear, linear motion is converted into rotational motion, providing power for the anti-static roller brush 102. The cleaning brush drive mechanism 200 also includes a rodless cylinder 202. The linear guide 2021 of the rodless cylinder 202 is arranged parallel to the circular rack 201. The bottom of the slider 2022 of the rodless cylinder 202 is fixedly connected to the mounting base 1121, so that the slider 2022 of the rodless cylinder 202 can drive the cleaning brush vacuum dust removal mechanism 100 to slide. When the rodless cylinder 202 is in operation, the slider 2022 drives the cleaning brush vacuum dust removal mechanism 100 to reciprocate relative to the linear guide 2021, thereby cleaning the surface of the flexible plate jig. The cleaning brush drive mechanism 200 also includes a linear slide rail 203, and the slider 2022 of the rodless cylinder 202 can slide back and forth on the linear slide rail 203, providing a stable motion track for the slider 2022 of the rodless cylinder 202, ensuring the straightness and stability of the slider 2022 when sliding.

[0046] In this embodiment, when the rodless cylinder 202 slides back and forth on the linear guide rail 203, the entire cleaning brush vacuum dust removal mechanism 100 moves back and forth along the circular rack 201 following the rodless cylinder 202. Since the circular rack 201 is engaged with the gear set 1122, it drives the anti-static roller brush 102 to rotate clockwise or counterclockwise, effectively lifting dust and foreign matter from the surface of the flexible plate jig into the vacuum suction port 111 on both sides. The reciprocating motion vacuums the flexible plate jig, effectively improving the dust removal effect. The cleaning brush drive mechanism 200 can drive the anti-static roller brush 102 to rotate clockwise or counterclockwise to meet the needs of various cleaning scenarios.

[0047] In this embodiment, the cleaning brush drive mechanism 200 also includes two limit sensors 204, which are respectively installed on the two end portions of the same side of the linear slide rail 203, and use precise sensing technology to monitor the position of the slider 2022 of the rodless cylinder 202 in real time; when the slider 2022 moves to the two ends of the flexible plate fixture, it automatically triggers a signal to control the reversal of the rodless cylinder 202, thereby realizing precise reciprocating motion of the cleaning mechanism.

[0048] In this embodiment, the bristles of the antistatic strip brush 101 and the antistatic roller brush 102 are preferably made of bristles, and the bristles are treated with antistatic treatment, and the surface resistance value thereof is within 10 6 Ω to 10 9 This material combines flexibility and wear resistance within the Ω range, ensuring it does not damage the surface of flexible board fixtures during cleaning. It also effectively suppresses static electricity and protects the fixture's conductive circuits and insulation. Other bristle materials can also be selected based on actual needs.

[0049] Please refer to Figure 5 In this embodiment, the suction port of the pneumatic vacuum cleaner 300 is connected to a conduit 1042 made of SUS304. A hose is connected to the suction port of the pneumatic vacuum cleaner 300, which is then connected to the conduit 1042. The cleaning brush vacuum mechanism 100 is provided with a stopper 110, which is fixedly mounted on a mounting base 1121. The stopper 110 is positioned at the junction of the conduit 1042 and the hose. The stopper 110 positions and limits the hose, preventing it from falling off and ensuring stable communication between the pneumatic vacuum cleaner 300 and the conduit 1042.

[0050] In this embodiment, the cross-sectional area of ​​the suction port of the pneumatic vacuum dust collector 300 is greater than or equal to the cross-sectional area of ​​the vacuum suction port 111 of the cleaning brush vacuum dust removal mechanism 100. This design ensures that the pneumatic vacuum dust collector 300 provides sufficient suction force to quickly collect dust and debris sucked in by the cleaning brush vacuum dust removal mechanism 100. Combined with the structure of the guide inner cover 107, it can prevent secondary deposition of dust and improve cleaning reliability and efficiency.

[0051] In this embodiment, the synchronous belt conveyor line mechanism 400 serves as an automatic conveyor line for flexible plate jigs, and can cooperate with the synchronous belt conveyor line automatic width adjustment mechanism 600 to automatically adjust the conveyor line width according to different batches of flexible plate jigs 500. The flexible plate jig clamps and positions the flexible circuit board between the upper and lower cover plates, and is clamped and positioned by the unilateral clamping mechanism 700; the cleaning brush driving mechanism 200 uses the rodless cylinder 202 to drive the gear set 1122 and the round rack 201 to drive the anti-static roller brush 102 to rotate forward and reverse, and at the same time realize the back and forth movement of the entire cleaning brush vacuum dust removal mechanism 100, so that the cleaning brush vacuum dust removal mechanism 100 can adopt a vacuum suction method, combined with the anti-static strip brush 101 and the anti-static roller brush 102, to clean the surface of the flexible plate jig through back and forth movement, and the pneumatic vacuum dust collector 300 achieves the dust removal effect of adsorbing dust and small debris by entering its interior with positive pressure gas and generating vacuum negative pressure at the other end. The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
