Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, and in particular to a chemical treatment liquid circulation treatment device for circuit board production. Background Art

[0002] The production of circuit boards is a complex and delicate process. First, raw materials such as copper clad laminates need to be prepared, which is the basis of circuit boards. During the production process, drilling operations are also required to install electronic components. After drilling, the holes are metallized to make the hole walls conductive. Then, the solder mask is made to protect the circuit and prevent short circuits. In addition, the circuit boards need to be surface treated.

[0003] In the production process of circuit boards, a series of complex processes are required, such as etching, copper plating, cleaning, etc. The etching process requires the use of a specific etching solution to remove the unnecessary copper foil part to form the required circuit pattern. Copper plating requires a copper plating solution to achieve the deposition of metal copper in a specific area of ​​the circuit board to ensure good conductivity and connectivity. The cleaning process also requires a corresponding chemical cleaning solution to remove pollutants and impurities on the surface of the circuit board. These chemical treatment solutions react specifically with the circuit board materials to achieve the purpose of achieving various process requirements. However, these chemical treatment solutions usually contain various chemical components. If they are directly discharged without proper treatment after use, they will cause serious harm to the environment and also lead to a waste of resources. Therefore, it is necessary to treat the chemical treatment solution during the production of the circuit board to achieve the effect of recycling.

[0004] However, when treating the chemical treatment liquid generated during the production of circuit boards, the chemical treatment liquid is generally directly subjected to multiple filtrations through a filter net. However, as the filtration proceeds, solid particles in the chemical treatment liquid gradually accumulate on the filter medium. The accumulated solid particles will cause the filter channel to become clogged. As the solid particles continue to accumulate, external forces will clean them, thereby reducing the filtration efficiency of the chemical treatment liquid and even completely blocking the filtration process. In addition, due to reasons such as the blockage of the filter channel and the uneven distribution of solid particles in the liquid, the filtration speed of the chemical treatment liquid will also gradually slow down, prolonging the processing time and reducing its processing efficiency. Therefore, it is necessary to provide a chemical treatment liquid circulation treatment device for circuit board production, aiming to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The transmission of the rotating shaft drives the rotating gear and the bevel gear 1 to rotate synchronously, so that the rotating gear drives the rotating gear ring and the fixed ring to rotate. The rotation of the fixed ring and the rotating gear ring facilitates the high-speed rotation of the filter cylinder. The centrifugal force generated by the high-speed rotation of the filter cylinder can filter the chemical treatment liquid entering the filter cylinder, so that the solid particles in the chemical treatment liquid are retained in the filter cylinder, and the liquid in the chemical treatment liquid is thrown into the fixed cylinder through the filter aperture on the filter cylinder, so as to achieve preliminary filtration of the chemical treatment liquid. When the bevel gear 1 rotates, it can facilitate the rotation of the bevel gear 2, which plays a role in power transmission. The bevel gear 2 can facilitate the rotation of the rotating rod and the eccentric wheel. When the side of the eccentric wheel farther from the rotating rod hits the bottom of the moving ring, the eccentric distance of the eccentric wheel can be The movable ring is pushed to slide upward, so that the filter cylinder and the chemical treatment liquid inside can be moved upward synchronously. When the side of the eccentric wheel closer to the rotating rod rotates to the bottom of the movable ring, the filter cylinder is caused to slide down by the compression rebound force of the compression spring 1 and the weight of the filter cylinder and the chemical treatment liquid. The filter cylinder and the chemical treatment liquid are rotated at high speed while sliding up and down continuously. The chemical treatment liquid can be vibrated and filtered again by the cooperation of the two. The centrifugal effect of the rotation and the disturbance caused by the vibration can separate solid particles of different particle sizes and densities from the liquid more efficiently, so as to achieve a better separation effect. The rotation can make large particles deposit quickly, and the vibration can prevent small particles from clogging the filter cylinder. The combination of the two effectively maintains the permeability of the filter cylinder, reduces the occurrence of clogging, and ensures continuous filtration.

[0018] 2. By sliding the filter screen cylinder up and down while rotating at high speed, the rotational force of the filter screen cylinder itself can push the dredging rod to move out from the inside of the filter screen cylinder aperture, and the dredging rod and the movable plate can compress the compression spring 2 inside the mounting rod when they move, and when the filter screen cylinder continues to rotate, the dredging rod that abuts against the outer wall of the filter screen cylinder can be slid into the filter screen cylinder under the thrust of the compression spring 2, so that the dredging rod and the movable plate can continuously slide back and forth, and by cyclically inserting the dredging rod into the apertures at different positions of the filter screen cylinder, the aperture of the filter screen cylinder can be dredged and prevented from being blocked, and while the filter screen cylinder rotates, the ultraviolet sterilization lamp board and the cleaning scraper are driven It rotates synchronously on the surface of the filter screen plate, and when the cleaning scraper slides on the top of the arc-shaped protrusion, the cleaning scraper and the filter screen plate are separated. When it is away from the arc-shaped protrusion, the cleaning scraper is reset by the elastic force of the compression spring three. The ultraviolet sterilization lamp board and the cleaning scraper cyclically slide up and down on the surface of the filter screen plate, which can vibrate the filter screen plate, and the cleaning scraper can scrape off small particles accumulated on the surface of the filter screen plate, thereby playing a role of preventing blockage again. The ultraviolet sterilization lamp board rotates in the chemical treatment liquid inside the fixed cylinder, and the filtered chemical treatment liquid can be sterilized and disinfected by the ultraviolet sterilization lamp board, so that the chemical treatment liquid can be recycled.

[0019] 3. The micro electric gas rod is used to start and push the moving gear ring to slide down and mesh with the adjusting gear. Therefore, when the inlet pipe and the filter cylinder rotate at high speed, the adjusting gear can be rotated at the bottom of the moving gear ring under the fixed position of the moving gear ring, so that the adjusting gear can rotate on its own. The rotation of the adjusting gear can drive the adjusting plate and the anti-skid gasket to rotate synchronously. The rotation of the adjusting plate can facilitate the control of the amount of chemical treatment liquid entering. The anti-skid gasket can increase the friction between the adjusting plate and the inlet pipe when the position of the adjusting plate is adjusted, thereby further improving the position stability of the adjusting plate. Reasonable control of the amount of chemical treatment liquid can ensure that the liquid and the filtration device are well matched during the filtration process, making the filtration more sufficient and thorough, and improving the impurity removal rate.

[0035] The multi-directional filter assembly 7 includes a rotating shaft 701 symmetrically connected to the inside of the driving seat 3 for rotation. A support plate 702 is fixedly connected to the top of the driving seat 3. A driving motor 703 is fixedly connected to the side of the support plate 702. The output shaft of the driving motor 703 is fixedly connected to one of the rotating shafts 701. A rotating gear 704 is fixedly connected to the surface of one of the rotating shafts 701. A fixing ring 705 is fixedly connected to the top of the filter screen cylinder 6. A rotating ring gear 706 is fixedly connected to the outer side of the fixing ring 705. The rotating gear 704 and the rotating ring gear 706 are meshed with each other. A fixing rod 707 is symmetrically fixedly connected to the top of the filter screen cylinder 6. A rotating ring 708 is fixedly connected to the top of the fixing rod 707. A moving ring 709 is rotatably connected to the outer side of the rotating ring 708. The moving ring 709 is slidably connected to the outer wall of the rotating shaft 701. A compression spring 714 is sleeved on the outer wall of the rotating shaft 701. The two ends of the compression spring 714 are fixedly connected to the moving ring 709 and the inner wall of the driving seat 3 respectively.

[0036] The multi-directional filtering assembly 7 also includes a bevel gear 1 712 fixedly connected to the outer wall of the rotating shaft 701, and the interior of the driving seat 3 is symmetrically rotatably connected to the rotating rod 710, and the outer wall of the rotating rod 710 is respectively fixedly connected to an eccentric wheel 711 and a bevel gear 2 713, and the bevel gear 1 712 and the bevel gear 2 713 are meshed with each other, and the eccentric wheel 711 and the moving ring 709 are in conflict with each other. The two rotating shafts 701 are connected by a belt drive, and the two eccentric wheels 711 are arranged in opposite states;

[0037] Specifically, the filter screen cylinder 6 in the multi-directional filter assembly 7 is driven to slide up and down while rotating at high speed. The high-speed rotation can increase the centrifugal force of the liquid and accelerate the separation speed of solid particles and liquid. At the same time, the up and down sliding vibration can prevent particles from clogging the filter screen cylinder 6. The combination of the two can significantly improve the overall filtration efficiency. The rotation and vibration can make the liquid and solid particles more evenly distributed in the filter screen cylinder 6, avoiding local accumulation and clogging, ensuring that the entire filter screen cylinder 6 can effectively play a filtering role, thereby obtaining a more uniform filtration effect. Stronger separation and better fluidity help to intercept more solid particles, reduce the residual impurities in the treated liquid, and improve the purity of the filtration. Continuous up and down sliding vibration can continuously clean the particles on the surface of the filter screen cylinder 6, reduce the probability of clogging, and extend the service life of the filter screen cylinder 6 and the continuity of filtration. This composite filtration method can process more chemical treatment liquids per unit time and improve the overall processing scale and capacity.

[0038] The dredging and anti-blocking component 8 includes a mounting rod 801 symmetrically arranged on the inner wall of the fixed cylinder 2, and a mounting cavity 802 is arranged inside the mounting rod 801. The inner wall of the mounting cavity 802 is fixedly connected with a compression spring 803, and one end of the compression spring 803 close to the filter screen cylinder 6 is fixedly connected with a push plate 804, and the side of the push plate 804 away from the compression spring 803 is fixedly connected with a push rod 805, and one end of the push rod 805 away from the push plate 804 is fixedly connected with a movable plate 806, and one side of the movable plate 806 away from the push rod 805 is fixedly connected with a dredging plug rod 807, and one end of the dredging plug rod 807 away from the movable plate 806 is inserted into the aperture of the filter screen cylinder 6;

[0040] Specifically, the dredging rod 807 in the dredging and anti-blocking assembly 8 is continuously and reciprocally inserted into the apertures at different positions on the filter screen cylinder 6, so that the solid particles blocked in the filter screen cylinder 6 can be dredged by the dredging rod 807. Through this insertion action, these particles can be effectively pushed away or scattered to prevent them from accumulating and forming a blockage, and by pushing the blocked solid particles from the outside of the filter screen cylinder 6 to the inside of the filter screen cylinder 6, the solid particles in the filter screen cylinder 6 can be prevented from flowing into the inside of the fixed cylinder 2, thereby further improving the treatment of the chemical treatment liquid. The filtration efficiency can be improved and the processing efficiency can be reduced due to clogging by solid particles. The rotation of the scraper 811 combined with the up and down sliding can contact the surface of the filter screen 809 in all directions and angles, ensuring the rapid and efficient scraping of the clogged solid particles, greatly improving the cleaning efficiency, and timely and effectively removing the clogged particles. The filter screen 809 can always be kept unobstructed, allowing the filtration process to continue smoothly and avoiding filtration interruption or reduced efficiency due to clogging. After the filter screen 809 is unobstructed, it can better play a filtering role and improve the filtration effect on the chemical treatment liquid.

[0042] Specifically, the adjustment plate 904 in the entry amount adjustment component 9 drives the anti-skid gasket 905 fixedly connected thereto to rotate synchronously inside the entry tube 5, and the anti-skid effect of the anti-skid gasket 905 can increase the position stability of the adjustment plate 904 through the anti-skid effect of the adjustment plate 904 after the angle adjustment of the adjustment plate 904 and the anti-skid gasket 905 is completed. The amount of chemical treatment liquid entering can be controlled by adjusting the spacing between the adjustment plate 904, the anti-skid gasket 905 and the entry tube 5. By reasonably controlling the amount, it can be ensured that the liquid and the filtering device are well matched during the filtration process, the filtration is more sufficient and thorough, and the impurity removal rate is improved. The amount of chemical treatment liquid can be accurately controlled according to actual needs to avoid excessive or insufficient amounts, thereby improving the utilization efficiency of resources such as chemical reagents and reducing costs. A stable amount helps to maintain the consistency of treatment conditions such as filtration, reduce the instability of treatment effects caused by fluctuations in amount, and ensure the stability of treatment quality.

[0047] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0048] In the initial state, compression spring 1 714 is in an uncompressed state, the eccentric wheel 711 and the movable ring 709 are in conflict with each other, compression spring 2 803 is in an uncompressed state, the clearing rod 807 is inserted in the aperture of the filter screen cylinder 6, compression spring 3 813 is in an uncompressed state, there is no conflict between the cleaning scraper 811 and the arc-shaped protrusion 810, the telescopic shaft of the micro electric gas rod 901 is in a retracted state, and the movable gear ring 902 and the adjusting gear 906 are in a non-meshed state.

[0049] When working:

[0050] After the staff connects the chemical treatment liquid discharge pipe with the inlet pipe 5, the chemical treatment liquid enters the interior of the filter screen cylinder 6 through the inlet pipe 5. At the same time, the staff starts the drive motor 703, and the drive motor 703 drives the rotating shaft 701 fixedly connected thereto to rotate, and the rotation of one of the rotating shafts 701 drives the other rotating shaft 701 to rotate synchronously in the same direction through the belt, and the rotation of the two rotating shafts 701 drives the bevel gear 1 712 and the rotating gear 704 fixedly connected thereto to rotate synchronously, and the rotation of the rotating gear 704 drives the rotating gear ring 706 meshing therewith to rotate, and the rotation of the rotating gear ring 706 drives the fixed gear 712 fixedly connected thereto to rotate synchronously.

Since the two rotating rods 710 rotate in opposite directions, the eccentric wheels 711 on the two rotating rods 710 are arranged in opposite states. Therefore, when the two rotating rods 710 drive the eccentric wheels 711 fixedly connected thereto to rotate simultaneously, the two oppositely arranged eccentric wheels 711 rotate synchronously at a position farther from the rotating rods 710 to the bottom of the moving ring 709 The eccentric distance of the eccentric wheel 711 can push the moving ring 709 to slide on the surface of the rotating shaft 701, and the compression spring 1 714 is in a compressed state at this time. When the eccentric wheel 711 is closer to the rotating rod 710 and rotates to the bottom of the moving ring 709, the compression rebound force of the compression spring 1 714 pushes the moving ring 709 to slide down and contact the surface of the eccentric wheel 711, and the moving ring 709 moves up and down to drive the rotating ring 708 connected to the rotating ring 708 to slide up and down synchronously, and the up and down sliding of the rotating ring 708 drives the fixed The connected fixed rod 707 slides up and down synchronously, and the fixed rod 707 drives the filter screen cylinder 6 fixedly connected thereto to slide up and down synchronously, so that the filter screen cylinder 6 can be driven to slide up and down while rotating at a high speed, and the centrifugal force of the liquid can be increased by high-speed rotation, thereby accelerating the separation speed of solid particles and liquid, and at the same time, the up and down sliding vibration can prevent particles from clogging the filter screen cylinder 6, and the combination of the two can significantly improve the overall filtration efficiency, and the rotation and vibration can make the liquid and solid particles more evenly distributed in the filter screen cylinder 6, avoiding local accumulation and clogging, and ensuring that the entire filter screen cylinder 6 can effectively play a filtering role, thereby obtaining a more uniform filtration effect, stronger separation effect and better fluidity help to intercept more solid particles, reduce the residual impurities in the treated liquid, and improve the purity of the filtration, and the continuous up and down sliding vibration can continuously clean the particles on the surface of the filter screen cylinder 6, reduce the probability of clogging, and extend the service life of the filter screen cylinder 6 and the continuity of filtration, and this composite filtration method can process more chemical treatment liquids per unit time, thereby improving the overall processing scale and capacity;

[0052] When the filter screen cylinder 6 rotates at a high speed, the rotation blocking force of the filter screen cylinder 6 can make the dredging rod 807 inserted in the aperture of the filter screen cylinder 6 be pushed out to contact the outer wall of the filter screen cylinder 6, and the movement of the dredging rod 807 drives the movable plate 806 fixedly connected thereto to move synchronously, and the movement of the movable plate 806 drives the push rod 805 fixedly connected thereto to move synchronously, and the movement of the push rod 805 drives the push plate 1 804 fixedly connected thereto to slide inside the mounting rod 801, and the compression spring 2 803 is in a compressed state at this time, and when the outer aperture position of the filter screen cylinder 6 rotates to the position of the dredging rod 807, the compression thrust of the compression spring 2 803 itself pushes the push plate 1 804 to reset, and the reset of the push plate 1 804 drives the push rod 805 fixedly connected thereto to reset, and the push rod 805 The reset of the movable plate 806 and the dredging rod 807 fixedly connected thereto move and reset synchronously, so that one end of the dredging rod 807 is inserted into the aperture of the filter screen cylinder 6, and the tapered end of the dredging rod 807 is continuously and reciprocally inserted into the apertures at different positions on the filter screen cylinder 6. Therefore, the solid particles blocked in the filter screen cylinder 6 can be dredged by the dredging rod 807. Through this plugging action, these particles can be effectively pushed away or scattered to prevent them from accumulating and forming a blockage. Moreover, by pushing the blocked solid particles from the outside of the filter screen cylinder 6 to the inside of the filter screen cylinder 6, the solid particles in the filter screen cylinder 6 can be prevented from flowing into the inside of the fixed cylinder 2, thereby further improving the treatment and filtration efficiency of the chemical treatment liquid, and effectively preventing the situation where the treatment efficiency is reduced due to the blockage of solid particles;

[0053] After the chemical treatment liquid is filtered through the filter screen cylinder 6, the chemical treatment liquid is filtered again through the filter screen plate 809. The aperture of the filter screen plate 809 is smaller than the aperture of the filter screen cylinder 6. Therefore, the filter screen plate 809 blocks and filters smaller solid particles in the chemical treatment liquid. The rotation of the filter screen cylinder 6 drives the mounting cylinder 812, the compression spring 813 and the cross rod 815 to rotate synchronously. The rotation of the cross rod 815 drives the ultraviolet sterilization lamp board 816 and the cleaning scraper 811 fixed thereto to rotate synchronously on the filter screen plate 816. 09, and when the bottom of the cleaning scraper 811 rotates to the curved surface of the arc-shaped protrusion 810, the protrusion of the arc-shaped protrusion 810 can push the cleaning scraper 811 and the ultraviolet sterilization lamp plate 816 to slide up synchronously, and the ultraviolet sterilization lamp plate 816 pushes the cross rod 815 fixedly connected thereto to slide up synchronously, and the sliding of the cross rod 815 can compress the compression spring three 813, and when the cleaning scraper 811 rotates away from the arc-shaped protrusion 810, the compression rebound force of the compression spring three 813 itself pushes the push plate two 814 to reset, and the push plate two 814 pushes the cross bar 815, the ultraviolet sterilization lamp board 816 and the cleaning scraper 811 to reset synchronously, so that the cleaning scraper 811 contacts the surface of the filter screen plate 809 again, and the cleaning scraper 811 continuously slides up and down to generate vibration force, and the cleaning scraper 811 continuously rotates on the surface of the filter screen plate 809 to scrape and clear the solid particles on the filter screen plate 809. The rotation of the cleaning scraper 811 combined with the up and down sliding can contact the surface of the filter screen plate 809 in all directions and angles to ensure that the solid particles blocking the filter screen plate 809 are cleared. The fast and efficient scraping of particles greatly improves the cleaning efficiency, timely and effectively removes the blocked particles, can always maintain the patency of the filter screen 809, so that the filtering process can continue smoothly, avoiding filtration interruption or reduced efficiency due to blockage. After the filter screen 809 is unblocked, it can better play a filtering role, improve the filtering effect of the chemical treatment liquid, and make the impurities more fully intercepted and separated. Through timely cleaning, the excessive wear and damage to the filter screen 809 caused by the long-term accumulation of particles is avoided, which is conducive to extending the service life of the filter screen 809;

[0054] When the filter screen cylinder 6 and the inlet pipe 5 rotate synchronously, the internal adjustment plate 904, the anti-skid gasket 905, the adjustment rod 903 and the adjustment gear 906 can be driven to rotate synchronously. The telescopic shaft of the micro electric gas rod 901 is controlled by an external controller to slide down and extend. The telescopic shaft of the micro electric gas rod 901 pushes the mobile gear ring 902 fixedly connected thereto to slide down to a meshing state with the adjustment gear 906, thereby causing the adjustment gear 906 to rotate at the bottom of the mobile gear ring 902. Since the position of the mobile gear ring 902 is in a fixed state, when the adjustment gear 906 rotates at the bottom of the mobile gear ring 902, the adjustment gear 906 realizes self-rotation, and the self-rotation of the adjustment gear 906 The adjusting rod 903 is driven to rotate, and the rotation of the adjusting rod 903 drives the adjusting plate 904 which is fixedly connected to it to rotate inside the entry tube 5, and the anti-skid washer 905 which is fixedly connected to it is driven to rotate synchronously inside the entry tube 5 through the adjusting plate 904, and the anti-skid effect of the anti-skid washer 905 can be used to increase the position stability of the adjusting plate 904 after the angle adjustment of the adjusting plate 904 and the anti-skid washer 905 is completed, and the spacing between the adjusting plate 904 and the anti-skid washer 905 and the entry tube 5 can be adjusted. After the spacing of the adjusting plate 904 inside the entry tube 5 is adjusted, the micro electric gas rod 901 is When the angle of the adjusting plate 904 needs to be adjusted again, the micro electric gas rod 901 is started again. By starting the micro electric gas rod 901 when needed, the energy waste of the micro electric gas rod 901 can be effectively avoided, and the situation of the adjusting plate 904 continuously rotating for angle adjustment can be avoided. The adjusting plate 904 can be adjusted in angle only when the amount of chemical treatment liquid entering needs to be adjusted. At the same time, the adjusting plate 904 can be kept in an adjusted state under the friction force of the anti-slip gasket 905, so that the amount of chemical treatment liquid entering can be controlled. The quantity control can ensure a good match between the liquid and the filter device during the filtration process, making the filtration more sufficient and thorough, improving the impurity removal rate, and accurately controlling the amount of chemical treatment liquid according to actual needs to avoid too much or too little, thereby improving the utilization efficiency of resources such as chemical reagents and reducing costs. A stable quantity helps to maintain the consistency of treatment conditions such as filtration, reduce the instability of treatment effects caused by fluctuations in quantity, and ensure the stability of treatment quality. The quantity can be flexibly adjusted to meet the needs of production or experiments of different scales, enhance the adaptability and versatility of the treatment process, and the appropriate quantity can reduce the burden on the equipment, reduce the risk of excessive wear and failure of the equipment due to handling large amounts of liquid, and extend the service life of the equipment.
