Description

Technical Field

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

[0002] In the manufacturing process of flexible printed circuit boards (FPCs), the surface cleaning treatment of flexible board fixtures is a key link to ensure product quality. With the development of electronic components towards miniaturization and precision, dust, metal debris and other tiny foreign objects are extremely likely to adhere to the surface of flexible board fixtures. If not removed in time, it will not only affect the accuracy of subsequent lamination, welding and other processes, but may also lead to circuit short circuits or performance failures. Traditional dust removal methods mostly use single brush sweeping or simple vacuum adsorption devices. These devices generally have problems such as single dust removal path and uneven adsorption force distribution, and are difficult to meet the cleaning requirements of high-precision flexible circuit boards.

[0003] In the prior art, some dust removal equipment does not consider anti-static design, and the static electricity generated during the cleaning process is likely to damage the insulating layer or conductive circuit of the flexible circuit board. At the same time, the separate structure of traditional brushes and vacuum adsorption cannot achieve the collaborative operation of "raising dust - adsorbing foreign objects", resulting in low dust removal efficiency and easy secondary pollution. Especially for flexible board fixtures with complex surface structures, traditional equipment is difficult to cover the corner and groove areas, resulting in cleaning blind spots.

[0004] In addition, the drive systems of existing dust removal equipment mostly use single-motor drive, lacking precise control over the rotation direction and movement trajectory of the brush, and unable to adjust the cleaning strategy according to the dust distribution characteristics. At the same time, the suction port size and air flow distribution design of the vacuum adsorption system lack systematic calculation, resulting in insufficient adsorption force or energy consumption waste, and it is difficult to meet the cleaning requirements of different batches of flexible board fixtures. Therefore, there is an urgent need for an integrated device with high-efficiency dust removal, anti-static performance and automatic control to solve the deficiencies in the prior art. Summary of the Invention

[0005] The main object of the present invention is to propose an anti-static vacuum dust removal equipment for cleaning flexible board fixtures, aiming to solve the problems of low dust removal efficiency and poor anti-static effect.

[0006] To achieve the above object, the present invention proposes an anti-static vacuum dust removal equipment for cleaning flexible board fixtures, including a cleaning brush vacuum dust removal mechanism for cleaning the surface of flexible board fixtures; The cleaning brush vacuum dust removal mechanism includes: Two anti-static strip brushes, which are scientifically arranged to cover a large area of the surface of the flexible board fixture. In a state of being at a short distance from the flexible board fixture, they form an effective barrier to create a vacuum adsorption isolation zone; The anti-static roller brush, with its unique roller shape, can penetrate into the fine gaps of the flexo fixture when rotating, effectively raising the hidden dust. The follow-up fixing seat, the transmission shaft of the anti-static roller brush is coaxially engaged with the follow-up fixing seat. The vacuum suction frame, which is composed of a U-shaped frame and a conduit. The U-shaped frame and the conduit are interconnected. The U-shaped frame is used to form a vacuum suction port channel, and the conduit transports the dust to the subsequent treatment device, forming an efficient dust transmission channel. Two sealing plates are respectively fixedly installed at the two ends of the U-shaped frame along its length direction. Two anti-static strip brushes are respectively fixedly installed on the outer surfaces of the two side walls of the U-shaped frame. One side of one of the sealing plates is closely attached to the follow-up 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 follow-up fixing seat to ensure the accurate transmission of the rotational power. The deflector plate is arranged inside the U-shaped frame. The two sides of its long side are respectively fixedly connected to the two side walls of the U-shaped frame. An interval space is formed between the lower surface of the deflector plate and the bottom plate of the U-shaped frame. A number of flow guiding holes distributed on the deflector plate are precisely calculated and designed, and their aperture and distribution density are highly adapted to the dust suction performance of the equipment, which can efficiently guide the dust. The flow guiding inner cover is in a U-shaped structure, and its opening direction is the same as that of the U-shaped frame. Its bottom plate is fixed on the side of the deflector plate away from the bottom plate of the U-shaped frame. An interval space is formed between the two side walls and the two side walls of the U-shaped frame. A U-shaped interval space is formed between the U-shaped frame and the flow guiding inner cover, and two vacuum suction ports are formed on both sides of the opening, which can quickly suck in the raised dust and sundries and make them pass through the flow guiding holes and enter the conduit. The top cover plate is fixedly installed on the outer surface of the bottom plate of the U-shaped frame for convenient subsequent quick disassembly and maintenance. Among them, a number of flow guiding holes are arranged on the deflector plate. A U-shaped interval space is formed between the U-shaped frame and the flow guiding inner cover. Two vacuum suction ports are formed on both sides of the opening direction of the U-shaped interval space. The dust and sundries sucked in by the vacuum suction ports can pass through the flow guiding holes and then enter the conduit.

[0007] Preferably, the anti-static vacuum dust removal device for flexible board fixture cleaning further includes a cleaning brush driving mechanism. The cleaning brush vacuum dust removal mechanism further includes a gear transmission mechanism. The gear transmission mechanism is arranged on the side of the U-shaped frame away from the U-shaped frame. The transmission shaft of the gear transmission mechanism is coaxially combined with the anti-static roller brush. The gear transmission mechanism is meshed and connected with the cleaning brush driving mechanism. The cleaning brush driving mechanism can drive the anti-static roller brush to rotate clockwise or counterclockwise to meet the needs of diverse cleaning scenarios.

[0008] 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 fixed seat, thereby forming a fixed connection with the vacuum dust collection frame. The other end of the mounting base is fixedly connected to the cleaning brush driving mechanism.

[0009] Preferably, the gear transmission mechanism further includes a gear set. The gear set is installed on the mounting base. After high-precision machining and strict quality inspection, the transmission is ensured to be accurate and stable. The cleaning brush vacuum dust removal mechanism is meshed and connected with the cleaning brush driving mechanism through the gear set to achieve efficient power transmission.

[0010] Preferably, the cleaning brush driving mechanism further includes a circular rack. The circular rack is meshed with the gear set. Through the transmission of the rack and the gear, the linear motion is converted into rotational motion to provide power for the anti-static roller brush.

[0011] Preferably, the cleaning brush driving mechanism further includes a rodless cylinder. The linear guide rail of the rodless cylinder is arranged in parallel with the circular rack. The bottom of the slider of the rodless cylinder is fixedly connected to the mounting base. Thus, the slider of the rodless cylinder can drive the cleaning brush vacuum dust removal mechanism to slide. When the rodless cylinder works, the slider drives the cleaning brush vacuum dust removal mechanism to reciprocate relative to the linear guide rail to achieve the surface cleaning of the flexible board fixture.

[0012] Preferably, the cleaning brush driving mechanism further includes a linear slide rail. The slider of the rodless cylinder can slide back and forth on the linear slide rail to provide a stable movement track for the slider of the rodless cylinder and ensure the straightness and stability during the sliding of the slider.

[0013] Preferably, the cleaning brush driving mechanism further includes two limit sensors. The two limit sensors are respectively installed at both ends of the same side of the linear slide rail. The precise induction technology is used to monitor the position of the slider of the rodless cylinder in real time. When the slider moves to both ends of the flexible board fixture, the signal is automatically triggered to control the rodless cylinder to reverse, realizing the precise reciprocating movement of the cleaning mechanism.

[0014] 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.

[0015] 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.

[0016] The beneficial effects of the technical solution of the present invention are: 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.

[0017] 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.

[0018] 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.

[0024] Please refer to Figures 1 to 5, in this embodiment, an anti-static vacuum dust removal device for flexible board fixture cleaning 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 board fixture 500, a synchronous belt conveyor line automatic width adjustment mechanism 600, and a single-side pressing mechanism 700, which are used for cleaning the surface of the flexible board fixture.

[0025] In this embodiment, Figure 1 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 suction frame 104, two sealing plates 105, a guide plate 106, a guide inner cover 107, and a top cover plate 108.

[0026] In this embodiment, the vacuum suction frame 104 is composed of a U-shaped frame and a conduit 1042. The U-shaped frame 1041 is composed of two side plates and a bottom plate. A window 1043 is opened on the bottom plate for subsequent maintenance design. The U-shaped frame is in communication with the conduit 1042. The U-shaped frame is used to form a vacuum suction port 111 channel, and the conduit 1042 transports dust to the subsequent processing device to form an efficient dust transmission channel. The two sealing plates 105 are respectively fixedly installed at the two ends of the U-shaped frame along its length direction. The two anti-static strip brushes 101 are respectively fixedly installed on the outer surfaces of the two side walls of the U-shaped frame. One side of one sealing plate 105 is closely attached to the follower fixed seat 103 to enhance the overall stability of the mechanism. That is, along the length direction of the U-shaped frame 1041, the structural order of being fixedly installed together in sequence is: the follower fixed seat 103, one sealing plate 105, the U-shaped frame 1041, and the other sealing plate 105. The transmission shaft of the anti-static roller brush 102 passes through the sealing plate 105 and is coaxially engaged with the follower fixed seat 103 to ensure accurate transmission of the rotational power. The guide plate 106 is arranged inside the U-shaped frame. The two long sides of it are respectively fixedly connected to the two side walls of the U-shaped frame. A spaced space is formed between the lower surface of the guide plate 106 and the bottom plate of the U-shaped frame, and this spaced space is in communication with the conduit 1042; several guide holes 1061 distributed on the guide plate 106 are designed through precise calculation, and their aperture and distribution density are highly adapted to the dust suction performance of the device, and can efficiently 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Please refer to Figure 3 、 Figure 4 、 Figure 5, in this embodiment, the cleaning brush driving mechanism 200 includes a circular rack 201. The circular rack 201 meshes with the gear set 1122. Through the transmission of the rack and the gear, the linear motion is converted into rotational motion to provide power for the anti-static roller brush 102. The cleaning brush driving mechanism 200 further includes a rodless cylinder 202. The linear guide rail 2021 of the rodless cylinder 202 is arranged in parallel with the circular rack 201. The bottom of the slider 2022 of the rodless cylinder 202 is fixedly connected to the mounting base 1121. Thus, 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 works, the slider 2022 drives the cleaning brush vacuum dust removal mechanism 100 to reciprocate relative to the linear guide rail 2021 to achieve the surface cleaning of the flexible board fixture. The cleaning brush driving mechanism 200 further includes a linear slide rail 203. The slider 2022 of the rodless cylinder 202 can slide back and forth on the linear slide rail 203 to provide a stable motion track for the slider 2022 of the rodless cylinder 202 and ensure the straightness and stability when the slider 2022 slides.

[0031] In this embodiment, when the rodless cylinder 202 reciprocates on the linear slide rail 203, the entire cleaning brush vacuum dust removal mechanism 100 will follow the rodless cylinder 202 and reciprocate along the circular rack 201. Since the circular rack 201 meshes with the gear set 1122, it drives the anti-static roller brush 102 to rotate clockwise or counterclockwise, effectively raising the dust and foreign objects on the surface of the flexible board fixture into the vacuum suction ports 111 on both sides, and performing vacuum dust removal on the flexible board fixture through reciprocating motion, effectively improving the dust removal effect. The cleaning brush driving mechanism 200 can drive the anti-static roller brush 102 to rotate clockwise or counterclockwise to meet the requirements of diverse cleaning scenarios.

[0032] In this embodiment, the cleaning brush driving mechanism 200 further includes two limit sensors 204. The two limit sensors 204 are respectively installed at both ends 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 both ends of the flexible board fixture, it automatically triggers a signal to control the rodless cylinder 202 to reverse, realizing the precise reciprocating motion of the cleaning mechanism.

[0033] In this embodiment, the bristles of the anti-static strip brush 101 and the anti-static roller brush 102 are preferably made of bristle, and the bristle material is anti-static treated, and its surface resistance value is in the range of 10 6 Ω to 10 9 Ω. This material has both flexibility and wear resistance, will not damage the surface of the flexible board fixture during cleaning, and effectively suppresses static electricity generation, protecting the conductive circuit and insulating layer of the fixture. Of course, other materials of bristles can also be selected according to actual needs.

[0034] Please refer toFigure 5 In this embodiment, the suction port of the pneumatic vacuum dust collector 300 is communicated with the conduit 1042. The conduit 1042 is a pipeline made of SUS304 material. The suction port of the pneumatic vacuum dust collector 300 is docked with a hose, and then the hose is docked to the conduit 1042. A limiting member 110 is provided on the cleaning brush vacuum dust collection mechanism 100. The limiting member 110 is fixedly installed on the mounting base 1121. The position of the limiting member 110 is set at the docking position of the conduit 1042 and the hose. The limiting member 110 can position and limit the hose to prevent the hose from falling off, ensuring that the pneumatic vacuum dust collector 300 can be stably communicated with the conduit 1042.

[0035] 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 collection mechanism 100. This design ensures that the pneumatic vacuum dust collector 300 provides sufficient suction force to quickly collect the dust and debris inhaled by the cleaning brush vacuum dust collection mechanism 100. Combined with the structure of the diversion inner cover 107, it can prevent secondary deposition of dust and improve the cleaning reliability and efficiency.

[0036] In this embodiment, the synchronous belt conveyor line mechanism 400 serves as an automatic conveyor line for flexible board fixtures. It can cooperate with the synchronous belt conveyor line automatic width adjustment mechanism 600 to automatically adjust the width of the conveyor line according to flexible board fixtures 500 of different batches. The flexible board fixtures clamp and position the flexible circuit board between the upper and lower covers, and are clamped and positioned by the single-sided pressing mechanism 700. The cleaning brush driving mechanism 200 uses the rodless cylinder 202 to drive the gear set 1122 and the circular rack 201 to drive the anti-static roller brush 102 to rotate forward and backward, and at the same time realizes the reciprocating movement of the entire cleaning brush vacuum dust collection mechanism 100, so that the cleaning brush vacuum dust collection mechanism 100 can adopt the vacuum suction method. Combining the anti-static strip brush 101 and the anti-static roller brush 102, the surface of the flexible board fixture is cleaned through reciprocating movement. The pneumatic vacuum dust collector 300 achieves the dust removal effect of adsorbing dust and small debris by the method of positive pressure gas entering its interior and generating vacuum negative pressure at the other end. The above are only partial or preferred embodiments of the present invention. Whether in terms of text or drawings, the scope of protection of the present invention cannot be limited thereby. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the overall concept of the present invention, or any direct / indirect application in other related technical fields is included in the scope of protection of the present invention.
