Description

Technical Field

[0001] This invention relates to the field of inactivated automotive filter technology, and more specifically, to a degumming device for the production and processing of inactivated automotive filters. Background Technology

[0002] Inactivated automotive filters are automotive air conditioning filter components with antiviral inactivation functions. They are based on a high-efficiency filter layer and an activated carbon adsorption layer, combined with inactivation coatings containing silver ions and photocatalysts. They effectively block impurities such as dust, fine particulate matter, pollen, and exhaust pollutants, while adsorbing and inactivating viruses, bacteria, and fungi in the airflow, reducing the risk of airborne transmission within the vehicle. Suitable for most passenger vehicle models, they effectively improve the cleanliness and health protection level of the in-vehicle air.

[0003] Currently, after the filter element and filter media are bonded and pressed together with the plastic frame, excess adhesive easily accumulates at the edges, requiring trimming and cleaning to ensure product dimensional accuracy and installation sealing. Existing methods for removing excess adhesive generally employ manual or mechanical scraping. Before processing, the adhesive layer needs to be softened by heating, and then scraped off using a scraper. This method has significant drawbacks: firstly, the softened adhesive layer still retains strong adhesion, easily adhering to the scraper surface during scraping, forming adhesive buildup. This reduces the fit of the scraping blade, making it impossible to thoroughly clean the edges of excess adhesive, and residual fine adhesive particles affect product appearance and assembly accuracy; secondly, the scraper and filter element are in hard contact, making precise force control difficult, easily scratching the edges of the filter media and the surface deactivation coating, resulting in decreased filter element performance, a high scrap rate, and difficulty meeting the processing requirements of large-scale mass production.

[0004] Therefore, based on the above, and drawing on years of experience in design, development and actual manufacturing in the relevant industry, the inventor has researched and improved the existing structure and its shortcomings, and provided a degumming device for the production and processing of inactivated automotive filter elements, in order to achieve a more practical value.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] As attached Figure 1 To be continued Figure 8 The device shown is a de-adhesive removal apparatus for the production and processing of inactivated automotive filter elements, comprising a base 100 and a filter element body 300. The base 100 serves as the supporting substrate, integrating a pressing and sealing mechanism, a low-temperature cooling mechanism, a multi-axis linkage grinding and adjustment mechanism, an intelligent detection mechanism, and a dust blowing and collection mechanism. This forms an integrated filter element de-adhesive removal processing structure that combines low-temperature hardening, intelligent alignment, precise grinding, and dust purification. It specifically addresses industry pain points in traditional automotive filter element de-adhesive removal processes, such as the soft texture of the hot melt adhesive making it difficult to clean, numerous grinding residues in dead corners, easy damage to the filter element substrate, lack of temperature control during processing, severe dust pollution, and low precision of manual adjustment. This effectively improves the de-adhesive removal accuracy and processing yield of filter elements, meeting the needs of large-scale filter element production and processing.

[0021] To address the problems of traditional filter element degumming processes, such as the lack of a sealed working space, exposed processing environment, easy loss of cold air, and easy dust spillage, resulting in poor cooling and shaping effects and serious workshop pollution, this equipment features a closed-loop, pressure-sealed degumming structure. A pressure mechanism is installed on the upper side of the base 100, including an upper frame 200 fixedly mounted above the base 100. Multiple sets of cylinders 201 are fixedly mounted on the upper frame 200, and the bottom extensions of the cylinders 201 are jointly fixedly mounted on a pressure seat 202. The pressure seat 202 and the base 100 cooperate to form a closed degumming chamber 203, where the filter element body 300 is confined and placed for closed processing. By driving the pressure seat 202 downwards and closing it through the cylinders 201, the degumming chamber 203 can be quickly sealed, effectively reducing cold air loss, improving cooling and shaping effects, and preventing grinding dust from drifting outwards, providing a basic environmental guarantee for dust-free, constant-temperature degumming processing.

[0022] To address the issues of traditional hot melt adhesives used in filter cartridges being soft and tough at room temperature, leading to stringing, residue adhesion, incomplete adhesive removal, and poor processing precision when directly polished, this equipment incorporates an intelligent constant-temperature low-temperature cooling mechanism. A semiconductor air cooler 402 is fixedly mounted on one side of the base 100. The outlet of the semiconductor air cooler 402 is fixedly connected to an exhaust pipe 403, the end of which is fixedly connected to an air supply adapter 400. Two sets of air inlet pipes 401 are symmetrically connected to the air supply adapter 400, with the ends of each set connected to one of the two adhesive removal chambers 203, ensuring even delivery of low-temperature cold air into the chambers. Simultaneously, a temperature monitoring sensor 404 is fixedly installed inside the adhesive removal chamber 203, and a PLC intelligent controller 1100 is fixedly mounted on the upper side of the pressure base 202. The temperature monitoring sensor 404 communicates with the PLC intelligent controller 1100 in real time. During operation, the semiconductor air cooler 402 can produce constant temperature air at 10-15℃. With the real-time temperature measurement of the temperature sensor and the intelligent control of the PLC, the glue removal chamber 203 is kept at a constant low temperature, which causes the hot melt glue overflowing from the edge of the filter element to harden and become brittle quickly, greatly reducing the difficulty of grinding and cleaning, and ensuring that the subsequent glue removal operation is clean and thorough.

[0023] To address the limitations of traditional filter element removal and polishing methods, such as fixed positions, limited stroke, inability to perform full-area reciprocating cleaning along the filter element edge, and the resulting issues of residual adhesive and numerous processing dead zones, this equipment incorporates a servo-driven precision lateral movement mechanism. A reciprocating moving block 500 is slidably mounted on the inner wall of the top side of the removal chamber 203. A reciprocating screw 501 is threadedly connected to the internal part of the reciprocating moving block 500. One end of the reciprocating screw 501 is rotatably mounted on the inner wall of the removal chamber 203. A first servo motor 502 is fixedly mounted on one end of the pressure seat 202. The output shaft of the first servo motor 502 is fixedly connected to the other end of the reciprocating screw 501, and the first servo motor 502 is electrically connected to the PLC intelligent controller 1100. Through PLC intelligent control of the first servo motor 502's forward and reverse rotation, the reciprocating screw 501 can be driven to rotate, causing the reciprocating moving block 500 to perform high-precision reciprocating linear motion along the filter element edge. This achieves full-area coverage movement of the polishing mechanism, completely eliminating polishing dead zones.

[0024] To address the shortcomings of traditional grinding mechanisms, which only offer a single lateral movement function and cannot adapt to the longitudinal processing position adjustment of filter elements of different specifications, resulting in poor equipment versatility and low alignment accuracy, this equipment incorporates an adaptive longitudinal adjustment mechanism. A transverse plate 600 is fixedly mounted on the bottom side of the reciprocating moving block 500. The transverse plate 600 has a downward-opening groove 601 inside. A lead screw 602 is rotatably mounted on the inner wall of the groove 601. An internally threaded slider 603 is threaded onto the lead screw 602. A second servo motor 604 is fixedly embedded on the outer side of the transverse plate 600. The output shaft of the second servo motor 604 is fixedly connected to the end of the lead screw 602. The second servo motor 604 is communicatively connected to a PLC intelligent controller 1100. Through precise PLC control of the second servo motor 604, the lead screw 602 can be driven to rotate, causing the internally threaded slider 603 to precisely shift longitudinally along the groove 601. This allows for flexible adjustment of the longitudinal processing position of the grinding mechanism, adapting to the adhesive removal needs of filter elements of different sizes and specifications, and improving equipment adaptability and processing alignment accuracy.

[0025] To address the problems of traditional grinding equipment with fixed grinding heights, which cannot adaptively adjust the grinding depth based on residual adhesive thickness and are prone to over-grinding and damaging the filter element substrate, or under-grinding leaving residual adhesive, this equipment is equipped with an electric precision lifting mechanism. A longitudinal moving plate 700 is fixedly mounted on the bottom side of the internally threaded slider 603, and an electric telescopic rod 701 is vertically fixedly mounted on the bottom side of the longitudinal moving plate 700. The electric telescopic rod 701 is electrically connected to the PLC intelligent controller 1100. Utilizing the controllable telescopic characteristics of the electric telescopic rod 701, the vertical height and grinding stroke of the grinding mechanism can be precisely adjusted. Combined with intelligent detection data, the grinding depth is adaptively adjusted, thoroughly removing residual adhesive from the surface while effectively avoiding structural damage to the filter element body caused by hard grinding, ensuring a high yield rate.

[0026] To address the limitations of traditional grinding mechanisms, which have fixed angles and can only grind a single plane, making them unsuitable for cleaning residual adhesive from multi-sided and multi-cornered filter elements, and resulting in difficulty in removing residual adhesive from corners, this equipment incorporates a large-angle adjustable deflection mechanism. A lifting base 800 is fixedly mounted on the bottom extension of the electric telescopic rod 701. A limit hole 801 is formed inside the lifting base 800, and a semi-cylinder 802 is rotatably assembled inside the limit hole 801. One end of the semi-cylinder 802 is fixedly connected to a connecting shaft 803. A motor plate 804 is fixedly mounted on the outside of the lifting base 800, and a third servo motor 805 is fixedly mounted on the motor plate 804. The output shaft of the third servo motor 805 is fixedly connected to the other end of the semi-cylinder 802. The third servo motor 805 drives the semi-cylinder 802 to achieve a precise 270° rotation within the limit hole 801, enabling the grinding mechanism to switch between multiple angles and postures. This allows for grinding of residual adhesive on the upper and lower surfaces, sides, and corners of the filter element, comprehensively covering all areas of the filter element to be processed.

[0027] To address the issues of uncontrollable rotation speed, unstable grinding force, and poor uniformity of residual adhesive removal in traditional adhesive removal and polishing methods, this equipment incorporates a high-speed, controllable polishing mechanism. A positioning seat 900 is fixedly mounted at the end of the connecting shaft 803 of the deflection mechanism. A polishing roller 901 is rotatably mounted on the positioning seat 900, allowing it to contact the edge of the filter element body 300. A motor mount 902 is fixedly mounted on the outside of the positioning seat 900, and a fourth servo motor 903 is fixedly mounted on the motor mount 902. The output end of the fourth servo motor 903 is fixedly connected to the end of the polishing roller 901. The fourth servo motor 903 precisely controls the high-speed, stable operation of the polishing roller 901, ensuring controllable rotation speed and uniform grinding force, guaranteeing the smoothness and consistency of residual adhesive removal, and preventing uneven polishing in certain areas.

[0028] To address the problems of traditional manual polishing, which lacks data support, makes it difficult to accurately determine the thickness of residual adhesive and the amount of polishing allowance, relies entirely on experience, and has a low error tolerance, this equipment is equipped with a laser intelligent detection mechanism. Two laser displacement sensors 904 are symmetrically fixed on the positioning base 900. Both laser displacement sensors 904 are tangentially arranged with respect to the polishing roller 901 and are electrically connected to the PLC intelligent controller 1100. The laser displacement sensors 904 can dynamically detect the thickness of residual adhesive on the filter element surface and the working position of the polishing roller in real time. The collected accurate data is transmitted to the PLC intelligent controller 1100 in real time. Through system data analysis and calculation, the operating parameters of each servo motor and electric telescopic rod are adaptively adjusted to achieve intelligent, precise, and unmanned polishing operation.

[0029] To address the problems of dust dispersion and adhesive residue accumulation during traditional filter element removal and polishing processes, which not only pollute the workshop environment but also easily accumulate on the filter element surface affecting processing quality and require tedious manual cleaning, this equipment is equipped with a fully automatic dust blowing and collection mechanism. The dust blowing mechanism is located on the opposite side of the base 100 from the cooling mechanism. This mechanism includes a guide pipe 1000, with two sets of connecting pipes 1001 symmetrically connected to it. These two sets of connecting pipes 1001 are respectively connected to two removal chambers 203. A filter plate 1004 and a dust collection box 1002 are fixedly mounted on the outside of the base 100. The dust collection box 1002 is connected to the end of the guide pipe 1000 via a connecting pipe 1003. The filter plate 1004 is fitted and installed at the connection between the connecting pipe 1003 and the dust collection box 1002, and the filter plate 1004 is communicatively connected to the PLC intelligent controller 1100. During operation, high-pressure airflow can be generated through filter plate 1004 to create a positive pressure environment inside the glue removal chamber 203, which quickly draws the fine glue chips and dust generated during grinding into the guide pipe 1000 and finally transports them to the dust collection box 1002 for unified collection. At the same time, air and dust separation can be achieved, effectively purifying the working environment and avoiding dust residue from affecting processing accuracy. In addition, the dust collection box can be easily opened for cleaning, making equipment maintenance convenient.

[0030] The working principle of this invention is as follows: During the degumming process of automotive filter elements, the entire process is coordinated and controlled by a PLC intelligent controller 1100, achieving fully automated closed-loop processing. In the initial stage, the filter element body 300 to be processed is stably placed on the corresponding workstation of the base 100. The position is adjusted so that the edges to be cleaned on both sides of the filter element extend into the two independent degumming chambers 203, completing precise workpiece loading and positioning. Subsequently, the PLC intelligent controller 1100 issues commands to drive multiple sets of cylinders 201 to extend downwards synchronously, causing the pressure seat 202 to press down smoothly and precisely engage with the base 100. This creates a completely sealed processing space between the two degumming chambers 203, preventing cold air leakage during subsequent cooling and preventing the diffusion of grinding dust, ensuring a closed and controllable processing environment.

[0031] After sealing, the process enters a low-temperature curing stage. The PLC intelligent controller 1100 activates the semiconductor air cooler 402, which cools the air to 10-15℃. The air is then evenly distributed through the exhaust pipe 403 into the air supply adapter 400, and then sent through two inlet pipes 401 into the two sealed adhesive removal chambers 203. Simultaneously, the temperature monitoring sensor 404 inside the adhesive removal chamber 203 collects the chamber temperature data in real time and feeds it back to the PLC intelligent controller 1100. The system dynamically adjusts the output power of the air cooler based on the temperature deviation, ensuring the chamber temperature remains stable within the set range of 10-15℃. Under the continuous low-temperature environment, the hot melt adhesive overflowing from the filter element edge cools, hardens, and becomes brittle, changing its soft, stringy, and sticky characteristics at room temperature. This significantly reduces the difficulty of subsequent grinding and cleaning, ensuring thorough adhesive removal and surface smoothness.

[0032] After cooling reaches the required standard, the grinding and cleaning process begins. The PLC intelligent controller 1100 first controls the fourth servo motor 903 to run, driving the grinding roller 901 into a high-speed rotation state. Simultaneously, the first servo motor 502 is started, driving the reciprocating screw 501 to rotate at a uniform speed, causing the reciprocating moving block 500 to move laterally along the edge of the filter element, first grinding and cleaning the residual adhesive on the upper surface of the filter element. During the operation, the laser displacement sensors 904 on both sides of the grinding roller 901 operate synchronously, monitoring the spatial position of the grinding roller in real time and accurately detecting the thickness distribution of residual adhesive on the filter element surface. The collected data is transmitted to the PLC intelligent controller 1100 in real time for calculation and analysis. The system dynamically adjusts the extension and retraction of the electric telescopic rod 701 according to the thickness of the residual adhesive, driving the high-speed rotating grinding roller 901 to accurately adjust the vertical grinding depth. While thoroughly removing the residual adhesive, it strictly avoids over-grinding and damaging the filter element substrate, balancing the thoroughness of adhesive removal with the integrity of the product structure.

[0033] After the grinding mechanism moves to the other end of the filter element, the PLC intelligent controller 1100 controls the electric telescopic rod 701 to extend fully downwards, so that the grinding roller 901 is adjusted to the working position tangent to the bottom surface of the filter element. Then, the first servo motor 502 is controlled to run in reverse, driving the grinding roller 901 to return along the original path, and simultaneously completing the cleaning of residual adhesive on the bottom surface of the filter element, realizing full coverage processing on both the top and bottom sides, with no blind spots in operation.

[0034] After the top and bottom surfaces are cleaned, the side residual adhesive removal process begins. The PLC intelligent controller 1100 starts the third servo motor 805, driving the semi-cylinder 802 to complete a precise 270° deflection within the limiting hole 801 of the lifting seat 800. Through the connecting shaft 803 and the positioning seat 900, the grinding roller 901 is switched from a horizontal to a vertical posture. After the posture adjustment is completed, the second servo motor 604 is started to drive the lead screw 602 to rotate, causing the internal thread slider 603 to move longitudinally. Through the electric telescopic rod 701 and the positioning seat 900, the grinding roller 901 is precisely aligned with the long side of the filter element. Subsequently, the fourth servo motor 903 drives the grinding roller 901 to rotate at high speed again, cooperating with the lateral reciprocating motion driven by the first servo motor 502 to completely remove the residual adhesive from the long side of the filter element, achieving full-dimensional adhesive removal without dead angles.

[0035] Throughout the entire degumming process, the dust blowing and collection mechanism operates synchronously and continuously. The PLC intelligent controller 1100 activates the filter plate 1004, continuously delivering high-pressure airflow into the guide pipe 1000. Combined with the low-temperature gas continuously supplied through the air supply adapter 400, this creates a stable positive pressure environment inside the degumming chamber 203. This entrains fine glue particles generated during grinding into the guide pipe 1000, and then transports them to the dust collection box 1002 via the connecting pipe 1003 for unified collection. The baffle structure inside the dust collection box prevents the high-speed airflow from stirring up the collected dust. Combined with the filter plate, this achieves efficient air-dust separation, with glue particles remaining inside the dust collection box while clean air is discharged. After long-term use, the equipment can be quickly cleaned by simply opening the sealed door of the dust collection box, making maintenance convenient and allowing for repeated use in production. After all degumming processes are completed, all mechanisms automatically reset, the pressure seat rises to open the degumming chamber, and the processed filter element can be removed, completing a single automated degumming operation.
