Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and more specifically, it relates to a dust removal machine for circuit board processing. Background Technology

[0002] A circuit board (PCB) is a core component of electronic devices. It is made of an insulating substrate and conductive copper foil laminated together, with precision circuitry formed by etching. It is used to connect electronic components and realize circuit functions. Its structure includes single-layer, double-layer, or multi-layer designs, and it features compact wiring, high reliability, and ease of mass production. It is widely used in computers, communications, home appliances, and other fields. In the PCB manufacturing process, dust removal is a critical step in ensuring product quality. It is mainly used to remove dust and debris generated during drilling, milling, and grinding. If these contaminants remain, they can lead to poor plating inside the holes, poor adhesion of solder resist ink, surface treatment defects, or misjudgments during inspection.

[0003] Existing circuit board dust collectors mostly require manual placement of circuit boards into the machine, clamping and securing them before dust removal. After dust removal, the boards must be manually removed before the next board is placed, resulting in slow operation. For example, the circuit board dust collector disclosed in Chinese patent document CN222343647U uses a manual loading and unloading method to remove dust from the circuit board surface. This method has poor flow-line operation efficiency and low efficiency in dust removal processing of circuit boards. It cannot be integrated with existing production line structures to achieve streamlined and continuous operation. Summary of the Invention

[0004] (1) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a dust collector for circuit board processing, so as to solve the technical problems of poor dust removal effect and low efficiency of the dust collector for circuit board processing mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A dust collector for circuit board processing includes a conveyor frame. Conveyor rollers are mounted on the conveyor frame via bearings, and a conveyor motor is mounted in conjunction with the conveyor rollers. The conveyor motor drives the conveyor rollers. Multiple conveyor belts are fitted onto the two sets of conveyor rollers. The conveyor belts are strip-shaped, with gaps between adjacent sets. The conveyor belts can be made of materials such as conductive silicone rubber, fluororubber, or antistatic polyurethane elastomer to prevent dust and impurities from adhering to them. A circuit board body is conveyed on the conveyor frame. Cleaning frames are vertically mounted on both the upper and lower sides of the circuit board body. A cleaning shaft is mounted in the center of the cleaning frame via a shaft and bearing. A rotation drive assembly is mounted on the outer side of the cleaning frame in conjunction with the cleaning shaft. The cleaning shaft has bristles and a blowing structure. A suction structure is mounted on the cleaning frame at the input end of the cleaning shaft, and a blowing assembly is mounted on the cleaning frame at the output end of the cleaning shaft.

[0006] The present invention is further configured such that the blowing assembly includes a blowing pipe, and a plurality of blowing heads are evenly arranged on the blowing pipe. Clean airflow is delivered to the blowing pipe and blown evenly toward the surface of the circuit board body through the blowing heads on the blowing pipe. This can further assist the brush bristles on the cleaning shaft and the blowing structure to further clean the residual dust and debris on the surface of the circuit board body, and improve the surface dust removal effect of the circuit board body during the processing.

[0007] The present invention is further configured such that the suction structure includes a negative pressure suction chamber, which is located at the input end of the cleaning rack. The output end of the negative pressure suction chamber is connected to a suction hose, which is externally connected to a negative pressure suction dust collection device. In the above process, the negative pressure suction chamber can provide negative pressure adsorption force, which can concentrate and collect the dust and debris cleaned by the rotation of the cleaning shaft and the impurities blown out by the blower into the negative pressure suction chamber under the action of negative pressure adsorption force. The impurities are then transported to the external negative pressure suction dust collection device for collection through the suction hose. The negative pressure suction dust collection device is a commonly used device in the existing dust removal field, and those skilled in the art should know it. The present invention will not elaborate on its structure and operating principle.

[0008] The present invention is further configured such that a mounting frame is provided on the conveyor frame, an electric push rod is provided on the mounting frame, and a cleaning frame is provided at the output end corresponding to the electric push rod. The movement and adjustment of the cleaning frame can be controlled by the electric push rod, so that the distance between the brush bristles, blower tube, etc. and the circuit board body can be flexibly adjusted according to the thickness of the circuit board and the required cleaning force, thereby improving the dust removal efficiency and effect of the circuit board body during dust removal.

[0009] The present invention is further configured such that mounting shafts are integrally provided at both ends of the sweeping shaft, and the sweeping shaft is mounted on the cleaning frame through the cooperation of the mounting shafts and bearings. The rotation drive assembly includes a rotation motor, and a synchronous belt drive structure is provided between the rotation motor and the mounting shaft. When the rotation motor is started, the rotation of the sweeping shaft can be controlled by the cooperation of the rotation motor and the synchronous belt drive structure, thereby causing the sweeping shaft to drive the brush bristles to rotate, so as to achieve brush cleaning of the circuit board surface.

[0010] The present invention is further configured such that the blowing structure includes a ventilation cavity, the ventilation cavity extends from the outer end of the mounting shaft into the interior of the brush bristles, and the ventilation cavity extends outward to the outer side of the brush bristles with a blowing hole. The blowing hole and the cleaning brush bristles are fitted with a clearance. The input end of the ventilation cavity is rotatably provided with an air inlet pipe through a sealed bearing. During the brushing and cleaning process described above, clean airflow can be delivered to the ventilation cavity through the air inlet pipe, and the airflow entering the ventilation cavity can be discharged outward through the blowing hole. This allows the surface of the brush bristles to be brushed. At the same time, dust and debris cleaned off the circuit board body by the brush bristles can be blown away in time and absorbed by the negative pressure suction cavity to prevent impurities from accumulating inside the brush bristles and improve the cleaning effect of the circuit board body.

[0011] The present invention is further configured to include an air supply device, wherein the output end of the air supply device is provided with an air delivery hose, the air delivery hose being a branch pipe, and the tail end being connected to the blower pipe and the air inlet pipe respectively. The air supply device can be an air pump or a fan, providing clean airflow for dust removal and cleaning of the circuit board. Here, the input end of the air supply device can achieve gas filtration and purification through existing technology. Under the action of the air supply device, the clean airflow is delivered to the blower pipe and the air inlet pipe respectively through the delivery hose to achieve the corresponding purging function. Each branch pipe can be individually controlled by a valve to open and close and control the airflow rate.

[0012] The present invention is further configured such that the output end of the cleaning rack is provided with a detection camera. When the circuit board is removed from the cleaning rack after cleaning, the surface of the circuit board can be visually inspected by the detection camera to monitor the dust removal effect of the circuit board body. The detection camera is a commonly used visual inspection industrial camera. Its use in conjunction with other electrical components through a controller is a well-known technology. The present invention will not elaborate on its circuit connection relationship, etc.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a dust removal machine for circuit board processing, which has the following beneficial effects: 1. High-efficiency automated dust removal operation This invention achieves continuous and automated dust removal for circuit boards through the coordinated design of a conveyor frame, conveyor belt, and cleaning frame. The conveyor belt uses a flexible strip material arranged at intervals with a gap design, which not only stably transports circuit boards but also facilitates the penetration of dust removal airflow from the bottom, effectively avoiding the efficiency bottleneck of traditional manual loading and unloading. The upper and lower opposing cleaning frame structure can simultaneously process both sides of the circuit board, and with the precise lifting and lowering adjustment of the electric push rod, it can adapt to the dust removal needs of circuit boards of different thicknesses. The dust removal process adopts a four-step coordinated mechanism of "negative pressure pre-suction - brush cleaning + airflow blowing - secondary airflow blowing - negative pressure collection", which significantly improves dust removal efficiency compared to traditional single-step dust removal methods. The integrated design of the detection camera enables online monitoring of the dust removal effect, ensuring that the dust removal quality of each circuit board meets the standards. The entire system can be seamlessly integrated with existing production lines, realizing the streamlined operation of the circuit board dust removal process.

[0014] 2. Multi-dimensional synergistic dust removal technology This invention organically combines mechanical cleaning with pneumatic dust removal, forming a three-dimensional dust removal network through the triple action of rotating brush cleaning, axial airflow injection through blowing holes, and auxiliary blowing through a blower. The ventilation chamber and blowing holes inside the cleaning shaft constitute a self-cleaning system, preventing dust from sticking back during brush cleaning via radial airflow, thus solving the problem of dust and impurities easily adhering to traditional dust brushes. The optimized design of the negative pressure suction chamber and the direction of the blowing airflow creates a "push-suction combined" dust control flow field, allowing the detached dust to be quickly guided into the collection system. The specially designed strip conveyor belt ensures the stability of circuit board transmission and provides an airflow channel for bottom dust removal, achieving a balanced dust removal effect on both sides and improving the dust removal effect and efficiency of the circuit boards.

[0015] 3. In this invention, the distance between the brush bristles and the circuit board is flexibly adjusted via an electric push rod, ensuring that the cleaning force adapts to different process requirements. The air supply system adopts a branch control design, which can independently adjust the airflow of the cleaning shaft and the air pressure parameters of the auxiliary blowing pipe to form an optimal dust removal air curtain. Visual data collected by the detection camera can be fed back to adjust the dust removal parameters, realizing closed-loop control of the dust removal process. All functional modules of the equipment (conveying speed, cleaning speed, airflow pressure, negative pressure intensity, etc.) can be digitally controlled by a PLC controller, and can store dust removal schemes for different circuit board models (which can be achieved by existing technology). This ensures the consistency and standardization of dust removal quality and improves the dust removal effect. Attached Figure Description

The conveyor belts 4 can be made of conductive silicone rubber, fluororubber, antistatic polyurethane elastomer, or other materials to prevent dust and impurities from adhering to them. A circuit board body is conveyed on the conveyor frame 1. Cleaning frames 6 are vertically mounted on both the upper and lower sides of the circuit board body. A cleaning shaft 7 is mounted in the center of the cleaning frame 6 via a shaft and bearing. A rotation drive assembly is mounted on the outer side of the cleaning frame 6 in conjunction with the cleaning shaft 7. The cleaning shaft 7 is equipped with bristles 8 and a blowing structure. A suction structure is mounted on the cleaning frame 6 at the input end of the cleaning shaft 7, and a blowing assembly is mounted on the cleaning frame 6 at the output end of the cleaning shaft 7.

[0022] The blowing assembly includes a blowing pipe 9, on which multiple blowing heads 10 are evenly arranged. Clean airflow is delivered to the blowing pipe 9 and blown evenly toward the surface of the circuit board body through the blowing heads 10 on the blowing pipe 9. This can further assist the brush bristles 8 on the cleaning shaft and the blowing structure to further clean the residual dust and debris on the surface of the circuit board body, thereby improving the surface dust removal effect of the circuit board body during the processing.

[0023] Please see Figures 1-5 As one implementation of the suction structure: the suction structure includes a negative pressure suction chamber 11, which is located at the input end of the cleaning rack 6. The output end of the negative pressure suction chamber 11 is connected to a suction hose 12, which is externally connected to a negative pressure suction dust collection device. In the above process, the negative pressure suction chamber 11 can provide negative pressure adsorption force, which can concentrate and collect the dust and debris cleaned by the rotation of the cleaning shaft 7 and the impurities blown out by the blower pipe 9 into the negative pressure suction chamber 11 under the action of negative pressure adsorption force, and then transport them to the external negative pressure suction dust collection device for collection through the suction hose 12. The negative pressure suction dust collection device is a commonly used device in the existing dust removal field, which should be known to those skilled in the art. The structure and working principle of this utility model will not be described in detail.

[0024] Please see Figures 1-5 As one embodiment of the conveyor frame 1: the conveyor frame 1 is provided with a mounting frame 13, the mounting frame 13 is provided with an electric push rod 14, and the cleaning frame 6 is provided at the output end of the corresponding electric push rod 14. The movement and adjustment of the cleaning frame 6 can be controlled by the electric push rod 14, so that the distance between the brush bristles 8, the blower pipe 9 and the circuit board body can be flexibly adjusted according to the thickness of the circuit board and the required cleaning force, thereby improving the dust removal efficiency and effect of the circuit board body during dust removal.

[0025] Please see Figures 1-5 As one implementation of the cleaning shaft 7: the cleaning shaft 7 has mounting shafts 15 integrally provided at both ends. The cleaning shaft 7 is mounted on the cleaning frame 6 through the cooperation of the mounting shafts 15 and bearings. The rotation drive assembly includes a rotation motor 16. A synchronous belt drive structure 17 is provided between the rotation motor 16 and the mounting shaft 15. When the rotation motor 16 is started, the rotation of the mounting shaft 15 can be controlled by the cooperation of the rotation motor 16 and the synchronous belt drive structure 17, thereby causing the cleaning shaft 7 to drive the brush bristles 8 to rotate, so as to achieve brush cleaning of the circuit board surface.

[0026] Please see Figures 1-5 As one implementation of the blowing structure: the blowing structure includes a ventilation cavity 18, which extends from the outer end of the mounting shaft 15 into the interior of the brush bristles 8. The ventilation cavity 18 extends outward to the outer side of the brush bristles 8 and has a blowing hole 19. The blowing hole 19 and the cleaning brush bristles 8 are fitted with a clearance. The input end of the ventilation cavity 18 is rotatably provided with an air inlet pipe 20 through a sealed bearing. During the brushing and cleaning process of the brush bristles 8, clean airflow can be delivered to the ventilation cavity 18 through the air inlet pipe 20, and the airflow entering the ventilation cavity 18 can be discharged outward through the blowing hole 19. This allows the surface of the brush bristles 8 to be brushed. At the same time, the dust and debris cleaned off the circuit board body by the brush bristles 8 can be blown away in time and absorbed by the negative pressure suction cavity 11 to prevent impurities from accumulating inside the brush bristles 8 and improve the cleaning effect of the circuit board body.

[0027] This utility model also includes an air supply device 21. The output end of the air supply device 21 is provided with an air delivery hose 22. The air delivery hose 22 is a branch pipe, and its tail end is connected to the blow pipe 9 and the air inlet pipe 20 respectively. The air supply device 21 can be an air pump or a fan to provide clean airflow for dust removal and cleaning of the circuit board. Here, the input end of the air supply device 21 can achieve gas filtration and purification through existing technology. Under the action of the air supply device 21, the clean airflow is delivered to the blow pipe 9 and the air inlet pipe through the delivery hose to achieve the corresponding purging function. Each branch pipe can be individually controlled by a valve to open and close and control the airflow.

[0028] Please see Figures 1-5 As one implementation of the cleaning rack 6: the output end of the cleaning rack 6 is equipped with a detection camera 23. When the circuit board is removed from the cleaning rack 6 after cleaning, the surface of the circuit board can be visually inspected by the detection camera 23 to monitor the dust removal effect of the circuit board body. The detection camera 23 is a commonly used visual inspection industrial camera. Its use in conjunction with other electrical components through a controller is a well-known technology. The circuit connection relationship of this utility model will not be described in detail.

[0029] In summary, the working principle and workflow of this utility model are as follows: In use, the circuit board body to be dusted can be placed on the conveyor belt 4, and the conveyor motor 3 controls the rotation of the conveyor roller 2 to move the conveyor belt 4, thereby driving the circuit board body to move forward. When moved to the cleaning rack 6, the circuit board body will first reach the negative pressure suction chamber 11. Under the action of negative pressure adsorption, the dust and debris on the surface of the circuit board body can be initially sucked up and cleaned. Then, when the cleaning shaft 7 is reached, the rotating motor 16 is started. Through the cooperation of the rotating motor 16 and the synchronous belt drive structure 17, the mounting shaft 15 can be controlled to drive the cleaning shaft 7 to rotate, thereby causing the cleaning shaft 7 to drive the brush bristles 8 to rotate, so as to clean the stubborn dust and impurities on the surface of the circuit board body. At the same time, clean airflow can be delivered to the ventilation chamber 18 through the air inlet pipe 20, and the airflow entering the ventilation chamber 18 can be discharged outward through the blow hole 19, so that the surface of the bristles 8 can be brushed. At the same time, the brush bristles 8 can promptly blow away the dust and debris that have been cleaned off the circuit board body, and assist in cleaning the dust and debris remaining on the surface of the circuit board body. During this process, the negative pressure suction generated by the negative pressure suction chamber 11 absorbs the dust and debris that are swept up, preventing impurities from accumulating inside the brush bristles 8 and improving the cleaning effect of the circuit board body. Afterwards, the circuit board body will reach the blower pipe 9. The airflow will be blown evenly towards the circuit board body through the blower head 10 on the blower pipe 9, and the airflow blown out by the blower head 10 and the airflow blown out by the cleaning shaft 7 will act on the circuit board body in a similar or the same direction. This can be used as an auxiliary means to thoroughly blow away and clean the impurities and dust remaining on the circuit board body, thereby improving the dust removal effect of the circuit board. After the circuit board body is cleaned and removed from the cleaning rack 6, the surface of the circuit board body can be visually inspected by the inspection camera 23 to monitor the dust removal effect of the circuit board body.

[0030] Furthermore, in this utility model, two sets of cleaning racks 6 and related structures are arranged on the upper and lower sides of the circuit board body. In this way, the upper and lower sides of the circuit board body can be cleaned simultaneously, improving the cleaning efficiency of the circuit board. When cleaning the bottom of the circuit board, the conveyor belt 4 is in between. However, the conveyor belt 4 is a flexible strip structure and is made of a dust-free material. Therefore, it will generate adaptive micro-deformation and vibration during the blowing and brushing process, so that the dust and impurities adhering to the surface of the circuit board body can be sucked away in time through the gap 5 between the two sets of conveyor belts 4, thus achieving cleaning. In this utility model, the synchronous belt drive structure 17 uses a transmission method in which the synchronous pulley and the synchronous belt are driven by tooth meshing. The synchronous belt drive has the characteristics of constant transmission ratio and stable transmission. It is widely used in multi-axis synchronous drive, as should be known by those skilled in the art. This utility model will not elaborate on this aspect. In this utility model, the operation of related electrical components such as motors and electric push rods can be controlled by a PLC controller according to a set program. The specific working process and working principle of this utility model have been described in detail. Based on the above working process and working principle, those skilled in the art should know the specific circuit connection relationship and implement it through existing technology. Furthermore, the circuit connection relationship between related electrical components and the specific driver program are not the subject of protection of this utility model, and this utility model will not elaborate on them.

[0031] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although the embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents. Of all the solutions mentioned above, those involving motors can be combined with reducers if necessary. The connection structure and working principle between the motor and the reducer are existing known technologies, and this utility model will not elaborate on them.
