Description

Technical Field

[0001] The invention belongs to the technical field of copper clad laminate dust removal, and in particular relates to a double-sided electrostatic dust removal device for copper clad laminates. Background Art

[0002] Copper clad laminate is a material widely used in electronic manufacturing, especially in the production of printed circuit boards. It is composed of a thin copper foil and an insulating substrate bonded by adhesives or other methods. Copper clad laminate is the basic material for PCB manufacturing and provides the conductive path required for electrical connection. The substrate of copper clad laminate will produce fibers, powder or tiny particles during processing. These fine substances will fall and adhere to the surface of the copper foil during the production process. In order to ensure that the subsequent processes can proceed smoothly and ensure the quality of the final product, the dust attached to the surface of the copper clad laminate needs to be removed.

[0003] The prior art discloses a device for removing glue powder from the surface of a copper clad plate with a patent announcement number of CN217474315U. The above patent arranges a sticky glue roller along the transmission path of the copper plate, a sticky paper roller is provided on the upper side of the sticky glue roller, a sticky glue roller connecting mechanism is provided at both ends of the sticky glue roller, a sticky paper roller connecting mechanism is provided at both ends of the sticky paper roller, and the sticky glue roller connecting mechanism is connected to a sticky glue roller lifting mechanism. The device absorbs glue powder on the surface of the copper plate through the sticky glue roller to prevent the surface from being scratched by glue powder when entering the subsequent stacking and collecting process; however, the following deficiencies still exist in actual use: from a practical point of view, the device is contact cleaning, and the cleaning part is composed of a sticky glue roller and a sticky paper roll. The contact cleaning has a poor cleaning effect on materials with a relatively large amount of dust, and requires designated operators for a long time, and consumes a large amount of sticky paper rolls every day, which increases the operating cost and maintenance difficulty.

[0004] Therefore, a double-sided electrostatic dust removal device for copper-clad laminates is needed to solve the problems in the prior art that contact-type adhesive dust removal is difficult to clean fine parts and consumables need to be replaced frequently. Summary of the invention

[0005] The object of the present invention is to provide a double-sided electrostatic dust removal device for copper-clad laminates to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a double-sided electrostatic dust removal device for copper-clad laminates, comprising a negative pressure dust collector, a frame and a gas storage tank, a conveying motor is installed inside the frame, a transmission gear set corresponding to the conveying motor is installed inside the frame, two lifting slides are arranged inside the frame, a dust suction pipe corresponding to the negative pressure dust collector is fixedly connected to one side of the frame, two stepping motors corresponding to the lifting slides are installed inside the frame, two cylindrical brushes are installed inside the frame, two ion wind knives are installed inside the frame, two super strong wind knives are installed inside the frame, a control circuit is installed inside the frame, a plurality of universal self-locking wheels are fixedly connected to the bottom of the frame, a touch screen is installed on one side of the frame, and an indicator light is fixedly connected to the top of the frame.

[0007] It should be noted in the solution that a plurality of supporting foot pads are provided at the bottom of the rack.

[0008] It is further worth noting that the output end of the transmission motor is fixedly connected to the transmission gear set.

[0009] It should be further explained that dust suction ports which are connected to dust suction pipes are arranged near the top and bottom of the frame.

[0010] As a preferred implementation, the output ends of the two stepper motors are both fixedly connected with threaded rods, and the outer walls of the two threaded rods are both rotatably connected with ball nut seats.

[0011] As a preferred embodiment, the two cylindrical brushes rotate in opposite directions.

[0012] As a preferred implementation, the two ion air knives are respectively arranged at the upper and lower ends inside the frame.

[0013] As a preferred implementation, the gas storage tank is externally connected to an air pump and is in continuous communication with the ion air knife and the super strong air knife.

[0014] Compared with the prior art, the double-sided electrostatic dust removal device for copper-clad laminate provided by the present invention has at least the following beneficial effects:

[0015] (1) By setting up a cylindrical brush, an ion air knife and a vacuum tube, the cylindrical brush cleans the dust and debris on the surface of the copper clad laminate, and the ion super wind curtain is used to remove and collect the dust and debris by the principle of negative pressure vacuum, replacing the traditional adhesive dust removal. The use of the cylindrical brush and the ion air knife does not directly contact the surface of the copper clad laminate, avoiding surface scratches, damage or glue stains caused by mechanical contact or adhesive residue. The front and back sides of the copper clad laminate can be cleaned at the same time, greatly improving production efficiency and reducing dependence on single-sided cleaning. It is suitable for mass production environments. The ion air knife and negative pressure vacuum system can effectively remove tiny dust and debris covering the surface, reduce circuit problems caused by dust pollution, improve cleanliness, and do not require the consumption of adhesive consumables, reducing long-term operating costs.

[0016] (2) By setting up a stepper motor and a lifting slide to cooperate, when cleaning different thicknesses and special warped materials, the height of the cylindrical brush and the ion air knife can be accurately set, so that it can adapt to copper clad laminates of different thicknesses, ensuring that whether the copper clad laminate is a thin plate or a thick plate, it can be efficiently and evenly cleaned, avoiding incomplete cleaning or damage to the material due to inappropriate height, reducing production stagnation caused by frequent height adjustment, and improving production efficiency; at the same time, a control circuit is set, and the corresponding negative pressure parameters and air pressure parameters are set by the PLC control system, and the timing of starting and stopping the ion air knife and the super air knife is set. Through the precise control of various parameters by the PLC system, the cleaning effect of each copper clad laminate is ensured to be consistent, avoiding the situation where the cleaning effect is unstable or uneven due to differences in human operation, and the result of each cleaning can maintain a high standard of uniformity, which helps to improve product quality.

[0017] (3) By setting universal self-locking wheels, the device can be easily moved and adjusted to adapt to different production needs and layout changes, thereby improving the flexibility of the equipment and facilitating the operator to position and adjust the equipment, reducing the difficulty of manual handling and improving work efficiency. At the same time, support pads are set at the bottom of the frame to increase the stability of the frame and prevent the equipment from shaking or tilting during operation, thereby improving the accuracy and effect of the dust removal process, and reducing the direct pressure of the equipment on the ground, preventing ground damage or depression caused by long-term friction or weight concentration.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] See also Figure 1-5 The present invention provides a double-sided electrostatic dust removal device for copper-clad laminates, comprising a negative pressure dust collector 1, a frame 2 and a gas storage tank 12, a conveying motor 3 is installed inside the frame 2, a transmission gear set 4 corresponding to the conveying motor 3 is installed inside the frame 2, two lifting slides 5 are arranged inside the frame 2, a dust suction pipe 6 corresponding to the negative pressure dust collector 1 is fixedly connected to one side of the frame 2, two stepping motors 7 corresponding to the lifting slides 5 are installed inside the frame 2, two cylindrical brushes 8 are installed inside the frame 2, two ion wind knives 9 are installed inside the frame 2, two super wind knives 10 are installed inside the frame 2, a control circuit 11 is installed inside the frame 2, a plurality of universal self-locking wheels 13 are fixedly connected to the bottom of the frame 2, a touch screen 14 is installed on one side of the frame 2, and an indicator light 15 is fixedly connected to the top of the frame 2.

[0027] Further as Figure 1-5As shown, it is worth mentioning that multiple supporting pads are arranged at the bottom of the rack 2. The multiple supporting pads can evenly distribute the weight of the rack 2, making the equipment more stable and reducing the tilting or shaking that may be caused by the imbalance of a single supporting point, thereby keeping the equipment in a fixed position during operation and improving the dust removal effect; multiple supporting pads can effectively adapt to different ground conditions, especially when the ground is uneven or has slight undulations, provide better supporting force, ensure that the equipment is not affected by the uneven ground, and reduce equipment deviation or damage; multiple supporting pads help reduce the vibration and noise of the equipment during operation, avoid the transmission of vibration to the entire rack 2, and reduce interference with the working environment, especially when the dust removal device requires high-precision operation, the shock absorption function helps to stabilize the working performance; the supporting pads can prevent the equipment from directly contacting the ground, reduce friction, and avoid the weight of the equipment directly causing indentations or damage to the ground.

[0028] Further Figure 1 As shown, it is worth mentioning that the output end of the conveying motor 3 is fixedly connected to the transmission gear set 4, and the connection between the transmission gear set 4 and the conveying motor 3 can ensure the stable operation of the cylindrical brush 8, so as to efficiently convey materials such as copper-clad laminates. This structure can maintain the smooth flow of materials and avoid affecting the work efficiency due to resistance or poor transmission; the rotation of the two cylindrical brushes 8 can effectively lift the dust on the surface of the copper-clad laminate, providing a better cleaning effect for the subsequent electrostatic dust removal. The movement of the cylindrical brush 8 not only helps to remove the dust accumulated on the surface, but also can lift the dust to the dust removal area, thereby preventing the dust from continuing to adhere to the surface of the material; in the dust removal process of the copper-clad laminate, negative pressure adsorption may cause the material to be adsorbed on the surface of the dust removal equipment, affecting the transmission and cleaning efficiency. The two cylindrical brushes 8 can prevent the material from being adsorbed on the equipment by negative pressure, ensuring the smooth transmission of the material, avoiding operational failures caused by adsorption problems, making the transmission system run smoothly and efficiently remove dust, and the material transmission and cleaning process is smoother, and will not be interrupted due to equipment jamming or dust accumulation, thereby improving the overall production efficiency and the continuity of the production line.

[0029] Further Figure 1As shown, it is worth mentioning that dust suction ports connected to the dust suction pipe 6 are provided near the top and bottom of the frame 2. The top and bottom dust suction ports can realize all-round dust adsorption. Since the copper clad laminate may generate dust on the upper and lower surfaces during the production process, the top and bottom dust suction ports can respectively adsorb the dust on the upper and lower surfaces to ensure that the dust removal covers the entire material surface and improve the dust removal effect. By providing the upper and lower dust suction ports, the air flow path can be effectively optimized, the overall dust collection efficiency can be improved, and the dust can be sucked away more evenly and quickly to avoid dust accumulation or retention. A certain part, thereby ensuring the cleanliness and stability of the equipment operation; the dust suction ports are set on the top and bottom to ensure the uniformity of negative pressure adsorption, avoid the problem of excessive or weak local negative pressure caused by a single dust suction port, make the negative pressure distribution of the dust suction system more uniform, and reduce the uneven dust removal effect caused by insufficient or excessive local suction; at the same time, the design of the upper and lower dust suction ports enables the equipment to adapt to different working conditions and material properties, especially when processing copper clad laminates with different thicknesses or materials, it can ensure that the dust removal at the top and bottom can be carried out smoothly, thereby improving the versatility and adaptability of the equipment.

[0030] According to the above working process, it can be known that: by setting the universal self-locking wheel 13, the device can be easily moved and adjusted to adapt to different production needs and layout changes, thereby improving the flexibility of the equipment and facilitating the operator to position and adjust the equipment, reducing the difficulty of manual handling and improving work efficiency; at the same time, a supporting foot pad is set at the bottom of the frame 2 to increase the stability of the frame 2 and prevent the equipment from shaking or tilting during operation, thereby improving the accuracy and effect of the dust removal process, and can also reduce the direct pressure of the equipment on the ground, preventing damage or depression to the ground due to long-term friction or weight concentration; by setting the cylindrical brush 8, the ion air knife 9 and the dust suction pipe 6, the cylindrical brush 8 cleans The dust and debris on the surface of the copper clad laminate are removed by the ion super wind curtain and collected by the principle of negative pressure dust suction, which replaces the traditional adhesive dust removal. The use of the cylindrical brush 8 and the ion air knife 9 does not directly contact the surface of the copper clad laminate, avoiding surface scratches, damage or glue stains caused by mechanical contact or adhesive residue. The front and back sides of the copper clad laminate can be cleaned at the same time, which greatly improves production efficiency and reduces dependence on single-sided cleaning. It is suitable for mass production environments. The ion air knife 9 and the negative pressure dust suction system can effectively remove the tiny dust and debris covering the surface, reduce circuit problems caused by dust pollution, and improve cleanliness. At the same time, there is no need to consume adhesive consumables, which reduces long-term operating costs.

[0031] Further Figure 1As shown, it is worth explaining in detail that the output ends of the two stepper motors 7 are fixedly connected with threaded rods, and the outer walls of the two threaded rods are rotatably connected with ball nut seats. The stepper motor 7 drives the threaded rods, which in turn drives the ball nut seats to rise. The ball nut seats can accurately adjust the height of the upper structure to ensure that the electrostatic dust removal device can efficiently and evenly remove dust from the copper clad laminate and adapt to materials of different specifications; the cooperation of the stepper motor 7, the threaded rods and the ball nut seats can achieve automatic adjustment, reduce manual intervention, save adjustment time, and improve production efficiency; the design of the ball nut seat provides higher stability and precision, effectively avoids friction and wear in traditional mechanical transmission, and improves the long-term stability of the equipment.

[0032] Further Figure 2 As shown, it is worth explaining in detail that the two cylindrical brushes 8 rotate in opposite directions, and the two cylindrical brushes 8 can cooperate with each other to avoid the copper clad laminate from being offset or stuck during the dust removal process, thereby ensuring that the copper clad laminate always maintains a stable position during the dust removal process, reducing the offset or scratches of the material, and ensuring the smooth transmission of the material; at the same time, the two cylindrical brushes 8 can exert uniform pressure on the material to avoid uneven friction caused by one-way transmission.

[0033] Further Figure 2 As shown, it is worth mentioning that two ion wind knives 9 are respectively arranged at the upper and lower ends inside the frame 2. The wind curtain generated by the ion wind knife 9 can directly act on the upper and lower surfaces of the copper clad laminate, blow up the dust obliquely, and effectively prevent the dust from continuing to adhere or pass. This wind curtain design can make the dust from the surface of the copper clad laminate be removed more quickly, effectively reduce the attachment, and improve the dust removal efficiency; the ion wind knife 9 acts on both sides of the copper clad laminate by oblique blowing, ensuring that both sides of the material can be cleaned at the same time. This double-sided dust removal design avoids the blind spots that may exist in single-sided dust removal, thereby ensuring that the entire surface can be thoroughly cleaned; the ion wind knife can neutralize the static electricity on the surface of the copper clad laminate by generating ion wind, reduce the electrostatic adsorption force, and thus prevent the dust from re-depositing on the surface; through the action of the ion wind knife 9, the dust is blown up and removed in time, reducing the dust concentration in the production environment, which helps to maintain a clean environment.

[0034] Further Figure 1As shown, it is worth specifically explaining that the air storage tank 12 is externally connected to the air pump and is connected with the ion wind knife 9 and the super wind knife 10. The air storage tank 12 provides a stable airflow through the air pump to ensure that the ion wind knife 9 and the super wind knife 10 can work continuously and stably, so as to maintain the high-efficiency dust removal ability of the wind knife and avoid the decrease of dust removal effect due to insufficient air pressure; the air storage tank 12 can store compressed air and is connected with the wind knife system through the air pump to optimize the use of airflow. The air pump can adjust the airflow as needed to avoid waste or insufficient airflow, thereby improving the overall energy saving. The resource utilization efficiency is improved and the operation cost is reduced; through the high-pressure air supply of the air storage tank 12, the airflow of the ion air knife 9 and the super air knife 10 can cover the surface of the copper clad laminate more evenly, ensuring a more uniform dust removal effect, especially when processing large-size copper clad laminates, the uniform airflow can effectively avoid certain areas from not being thoroughly cleaned due to uneven airflow; at the same time, the design of the air storage tank 12 can ensure the continuous supply of airflow and avoid frequent startup and shutdown of the air pump, which helps to improve the operating stability of the equipment, extend the service life of the air pump and air knife system, and reduce maintenance and failure rates.

[0035] This solution has the following working process: in actual use, the device is moved to the specified position and locked in position through the universal self-locking wheel 13, and the copper-clad laminate with dust removal is placed between the two cylindrical brushes 8. The conveying motor 3 is turned on to drive the two cylindrical brushes 8 to rotate, so that the cylindrical brushes 8 convey the copper-clad laminate and raise dust and prevent negative pressure from sucking the plate. At the same time, the two ion wind knives 9 are turned on to blow out the wind curtain, obliquely blowing the upper and lower surfaces of the copper-clad laminate to prevent dust from passing through, and the wind curtain raises dust. Finally, all the dust is sucked into the negative pressure dust collector 1 through the suction port. When cleaning materials of different thicknesses and special warping, the stepper motor 7 is turned on to drive the threaded rod, which in turn drives the ball nut seat to rise, thereby adjusting the height of the upper structure to adapt to copper-clad laminates of different specifications.

[0036] In summary: by providing the universal self-locking wheel 13, the device can be easily moved and adjusted to adapt to different production needs and layout changes, thereby improving the flexibility of the equipment, facilitating the operator to position and adjust the equipment, reducing the difficulty of manual handling, and improving work efficiency; at the same time, a supporting foot pad is provided at the bottom of the frame 2 to increase the stability of the frame 2 and prevent the equipment from shaking or tilting during operation, thereby improving the accuracy and effect of the dust removal process, and also reducing the direct pressure of the equipment on the ground, preventing the ground from being damaged or sunken due to long-term friction or weight concentration;

[0037] By arranging the cylindrical brush 8, the ion air knife 9 and the dust suction pipe 6 to cooperate, the cylindrical brush 8 cleans the dust and debris on the surface of the copper clad laminate, and at the same time uses the ion super wind curtain to remove and collect the dust and debris by the principle of negative pressure dust suction, replacing the traditional adhesive dust removal. The use of the cylindrical brush 8 and the ion air knife 9 does not directly contact the surface of the copper clad laminate, avoiding the problem of surface scratches, damage or glue stains caused by mechanical contact or adhesive residue. The front and back sides of the copper clad laminate can be cleaned at the same time, which greatly improves the production efficiency and reduces the dependence on single-sided cleaning. It is suitable for mass production environments. The ion air knife 9 and the negative pressure dust suction system can effectively remove the tiny dust and debris covering the surface, reduce circuit problems caused by dust pollution, and improve cleanliness. At the same time, there is no need to consume adhesive consumables, which reduces long-term operating costs. The dust larger than 30μm can reach a removal rate of 99.99%, and the dust less than or equal to 30μm can reach a removal rate of 99%, and the static value is less than 35V;

[0038] By setting the stepper motor 7 and the lifting slide 5 to cooperate, when cleaning different thicknesses and special warped materials, the heights of the cylindrical brush 8 and the ion air knife 9 can be accurately set to adapt to copper clad laminates of different thicknesses, ensuring that whether the copper clad laminate is a thin plate or a thick plate, it can be efficiently and evenly cleaned, avoiding incomplete cleaning or damage to the material due to inappropriate height, reducing production stagnation caused by frequent height adjustment, and improving production efficiency; at the same time, a control circuit 11 is set, and the corresponding negative pressure parameters and air pressure parameters are set by the PLC control system, and the timing of starting and stopping the ion air knife 9 and the super air knife 10 is set. Through the precise control of various parameters by the PLC system, the cleaning effect of each copper clad laminate is ensured to be consistent, avoiding the situation where the cleaning effect is unstable or uneven due to differences in human operation, and the result of each cleaning can maintain a high standard of uniformity, which helps to improve product quality.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
