Description

Technical Field

[0001] This invention relates to the field of high-density molded sponge processing technology, specifically to a flipping system for high-density molded sponge composite processes. Background Technology

[0002] High-density sponge is a type of sponge classified by density within the industry, referring to sponges weighing 25 kg or more per cubic meter. According to customs classification standards, a density ≥25 kg / m³ is high-density, 24-18 kg / m³ is medium-density, and below 18 kg / m³ is low-density. Its physical characteristics include small pores, high mass, and generally high hardness, but this can be adjusted by adding ultra-softening agents. In short, high-density molded sponge is a sponge product processed with special techniques; it not only has high density but also good support, durability, and shape retention.

[0003] High-density molded sponge composite process is a process that firmly bonds high-density molded sponge with other materials (such as fabric, leather, plastic, film, other sponges, etc.) through specific technologies; for example, a high-density sponge roller bonding turning machine with application number 201520958711.X discloses in its background technology that high-density sponge is bonded together with other types of sponge by adhesive.

[0004] During the production of high-density foam, non-polar release agents (such as silicone oils) or oil stains are easily left behind. It is difficult to remove them by simply using existing ion guns and cleaning cloths. Alternatively, simple solvent wiping may result in uneven wiping or improper dosage control, causing solvent residue that affects bonding and hinders the high-density molded foam composite process that firmly bonds the foam to other materials with adhesive. Summary of the Invention

[0005] To address the issue that non-polar release agents (such as silicone oils) or oil stains are easily left behind during the production of high-density foam, it is difficult to remove them simply using existing ion guns and cleaning cloths. Simple solvent wiping may result in uneven cleaning or improper dosage control, leading to solvent residue that negatively impacts adhesion. To achieve the above objectives, this invention provides the following technical solution: A flipping system for a high-density molded sponge composite process includes a composite pretreatment box with a pretreatment channel. A conveyor belt is installed along the pretreatment channel to transport high-density sponge. A flipping frame is installed inside the pretreatment channel. The flipping frame includes a first pretreatment frame assembly, a support and adjustment frame, and a second pretreatment frame assembly. The first and second pretreatment frame assemblies are symmetrically distributed. The support and adjustment frame supports the first and second pretreatment frame assemblies and can adjust the distance between them. The support and adjustment frame limits the high-density sponge between the first and second pretreatment frame assemblies from both sides. The support and adjustment frame is mounted on a flipping robotic arm, which periodically flips and shakes the impurities on the high-density sponge. Pretreatment frame group one and pretreatment frame group two adopt the same structure. Pretreatment frame group two includes a support frame structure and a high-density sponge cleaning head. The support frame structure is assembled on the support adjustment frame, and the high-density sponge cleaning head is slidably assembled on the support frame structure. The high-density sponge cleaning head can slide back and forth along the support frame structure. The high-density sponge cleaning head includes a dust removal component and a stubborn impurity cleaning component. The dust removal component and the stubborn impurity cleaning component are assembled side by side. The dust removal component is used to monitor the stubborn impurities of residual non-polar release agent or oil stains during the dust removal process of the high-density sponge, and the stubborn impurity cleaning component is used for targeted removal.

[0006] In an optimized configuration, the two ends of the impact dust collector are mounted on a support frame structure, and the impact dust collector includes: Support beam one; Two mounting plates are distributed at the ends of the support beam; the two mounting plates and the support beam are on the same straight line. Multiple electrically operated telescopic rods are arrayed on the wedge-shaped surface of the supporting beam; the wedge-shaped surface is formed on the front end surface of the supporting beam.

The dust extraction port is located on the support beam; the dust extraction port is connected to the vacuum cleaner via a connecting hose.

[0007] The supporting beam is equipped with a sensor at its front end for detecting non-polar release agents or oil stains. The sensor includes an ultraviolet fluorescence sensor and an infrared sensor. The ultraviolet fluorescence sensor uses ultraviolet light of a specific wavelength to irradiate the oil stains and release agents, which are excited to produce fluorescence. The non-polar release agent or oil stain is detected by detecting the fluorescence intensity. The infrared sensor analyzes the characteristic absorption of chemical bonds, including CH bonds, in specific infrared bands in the oil stains and release agents.

Wedge-shaped block two is integrally fixed on rotating disk two; Wedge-shaped block three is integrally fixed on rotating disk two; Among them, wedge block two and wedge block three are distributed in a straight line. Both wedge block two and wedge block three are provided with arc-shaped inclined surfaces. The arc-shaped inclined surfaces of wedge block two and wedge block three face opposite directions to ensure uniformity of direction during rotation. Multiple solvent outlet holes are opened on the arc-shaped inclined surfaces of wedge block two, and multiple solvent outlet holes are connected to rotating tube two. Multiple brush strips are fixed on the arc-shaped inclined surfaces of wedge block three.

[0011] The vacuum recovery disc includes: Rotary disk one is connected to motor one via a combination of rotating tube one and rack ring one for power transmission; one end of rotating tube one is located on the columnar center line of the rotating disk one, and the other end is rotatably connected to connecting tube one via a sealed bearing ring one, and connecting tube one is connected to the material extraction hole; rack ring one is fitted outside the main body of rotating tube one, and rack ring one is connected to motor one for power transmission via a drive gear one.

A vacuum adsorption tube is assembled on the columnar centerline of a rotating disk; the vacuum adsorption tube is connected to the rotating disk.

[0012] The optimized support frame structure includes: The support frame is mounted on the support adjustment bracket; Two sets of drive tracks are symmetrically distributed on the support frame; each set consists of two drive tracks, which are arranged in parallel. The drive track includes: The guide plate is fixed to the support frame as a single unit; The drive slots are formed on the guide plate and distributed along the main body of the guide plate; The lead screw is rotatably assembled inside the drive groove and distributed along the main body direction of the drive groove; A drive slider is slidably mounted on a drive groove; the drive slider is sleeved on the lead screw and is threadedly connected to the lead screw. The support column is fixed at one end to the drive slider and at the other end to the end of the dust removal component.

[0013] The optimized support adjustment frame includes: A U-shaped support plate is added to the tilting robotic arm; Two parallel support strips are fitted onto the U-shaped support plate; the support strips are equipped with multiple mechanical grippers. Multiple hydraulic telescopic rods are distributed at the ends of the support strip plate; one end of each hydraulic telescopic rod is fixed to the support strip plate, and the other end is fixed to the support frame structure.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The conveyor belt transports the high-density sponge to be glued and laminated into the pre-treatment channel. A robotic arm picks up the high-density sponge and places it between the already opened pre-treatment frame group one and pre-treatment frame group two. Then, the support adjustment frame is used to reduce the distance between pre-treatment frame group one and pre-treatment frame group two. At the same time, the support adjustment frame limits the high-density sponge between pre-treatment frame group one and pre-treatment frame group two from both sides. As the high-density sponge cleaning head slides back and forth along the support frame structure, it uses a tapping dust removal device to tap and remove dust from the high-density sponge. At the same time, it monitors for stubborn impurities such as residual non-polar release agent or oil stains. After stubborn impurities such as residual non-polar release agent or oil stains are detected at a certain point on the high-density sponge, a stubborn impurity cleaning device is used for targeted removal. This achieves precise removal of stubborn impurities such as residual non-polar release agent or oil stains using solvent, ensuring that stubborn impurities such as non-polar release agent or oil stains are removed while avoiding solvent residue. 2. During movement, the dust removal component uses multiple electric telescopic rods to periodically extend and retract, driving the striking ball to strike the high-density sponge. This releases easily stuck or tangled debris from the sponge, allowing for rapid removal via the vacuum cleaner's suction port. This solves the problem of debris sticking and getting stuck due to the hard and brittle texture of the high-density sponge. The vibration generated by the striking loosens and dislodges deep-seated debris, preparing for subsequent deep cleaning and working in conjunction with the suction port for initial cleaning. 3. After the support beam 1 detects stubborn impurities such as residual non-polar release agent or oil stains using an ultraviolet fluorescence sensor or infrared sensor, the pneumatic telescopic rod is activated. During the extension and retraction of the pneumatic telescopic rod, the guide slider moves laterally along the guide groove on the support beam 2, delivering the fixed-point cleaning component to the location of the residual non-polar release agent or oil stains. The hydraulic cylinder lowers the vacuum recovery disc and the fixed-point cleaning disc to the location of the non-polar release agent or oil stains on the high-density sponge. Motor 2 starts, and through the power transmission cooperation of rack ring 2 and drive gear 2, the power is transmitted to rotating tube 2 and rotating disk 2. Rotating disk 2 drives wedge block 2 and wedge block 3 to rotate synchronously. Wedge block 2 utilizes multiple solvents on its arc-shaped inclined surface. The solvent is released through the discharge hole. After the solvent comes into contact with the non-polar release agent or oil stains, multiple brush strips on the three arc-shaped inclined surfaces of the wedge block clean it, promoting the contact and mixing of the solvent with the non-polar release agent or oil stains. This completes the targeted removal of stubborn impurities using the cleaning parts, achieving precise removal of stubborn impurities such as residual non-polar release agent or oil stains using the solvent. Once the motor is started, the power is transmitted to the rotating tube and the rotating disk through the gear ring and the drive gear. The rotating disk uses multiple vacuum adsorption holes on multiple wedge blocks to squeeze and vacuum separate the solvent and stubborn impurities from the high-density sponge, ensuring the removal of stubborn impurities such as non-polar release agent or oil stains while avoiding solvent residue. 4. The drive motor, through a lead screw and drive slider threaded transmission, adjusts the longitudinal movement of the dust removal and stubborn impurity cleaning components, thus delivering the vacuum recovery tray and the fixed-point cleaning tray longitudinally. Simultaneously, the combined pneumatic telescopic rod extends and retracts, driving the guide slider to move laterally along the guide groove on the second support beam, thus delivering the vacuum recovery tray and the fixed-point cleaning tray laterally. This ensures that the vacuum recovery tray and the fixed-point cleaning tray are precisely delivered above the location of residual non-polar release agent or oil stains. The hydraulic cylinder then lowers the vacuum recovery tray and the fixed-point cleaning tray onto the non-polar surface of the high-density sponge. At locations with mold release agents or oil stains, it can accurately deliver the solution in three dimensions, which is beneficial for the precise use of solvents to remove stubborn impurities such as residual non-polar mold release agents or oil stains. Equipped with ultraviolet fluorescence sensors or infrared sensors, it can accurately identify non-polar mold release agents or oil stains that are difficult to detect by ordinary cleaning methods in a non-contact manner. Once a contaminant is detected, a three-dimensional precision moving platform (consisting of longitudinal movement controlled by a drive motor and lead screw, lateral movement controlled by a pneumatic telescopic rod and guide groove, and vertical movement controlled by a hydraulic cylinder) will be activated to accurately deliver the end effector directly above the contamination point. 5. Addressing the issue that vigorous scrubbing or soaking can damage the pore structure of high-density sponges, while simple wiping is insufficient to clean the interior; the tapping dust removal component of this application loosens debris through vibration, avoiding damage to the surface caused by vigorous scraping; the brush strips of the spot cleaning disc perform localized fine cleaning only on the soiled areas, rather than large-area rough friction; the vacuum recovery disc extracts the waste liquid through negative pressure, rather than rinsing with water, which would allow solvents and dirt to penetrate deep into the sponge; thus, it achieves efficient removal of stubborn dirt while maximizing the protection of the physical structure and integrity of the high-density sponge itself. 6. The biggest challenge after using solvents to remove oil stains is solvent residue. This residual solvent itself becomes a new contaminant, affecting subsequent bonding or lamination processes. The vacuum recovery tray and the fixed-point cleaning tray of this application work together. Instead of spraying solvent and waiting for it to evaporate, it immediately "grabs" and recovers the solvent along with the dissolved dirt from the substrate the moment the solvent has completed its dissolution task. This not only solves the original oil stain problem, but also efficiently solves the solvent residue problem, achieving true cleaning rather than "contamination replacement," providing an extremely clean surface for subsequent processes. 7. Traditional cleaning methods often consume large amounts of solvent or water and generate a large amount of wastewater that needs to be treated. This application uses precise, targeted solvent application, which minimizes the amount used. At the same time, the vacuum recovery disc can recover most of the used solvent, which can be recycled after treatment. This makes it a highly efficient, environmentally friendly, and energy-saving device that significantly reduces chemical consumption and wastewater treatment costs in the production process. 8. It integrates multiple functions such as macroscopic physical impaction, microscopic chemical dissolution, mechanical scrubbing to aid dissolution, and vacuum negative pressure recovery into one device, which can solve various pollution problems from solid debris to stubborn oil stains in one process; the modules are not simply stacked, but are organically combined through intelligent detection and precise positioning, which produces a synergistic effect and the overall efficiency is far higher than that of step-by-step processing.

Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. In the description of the present invention, unless otherwise stated, "a plurality of" means two or more.

[0018] In embodiments of the present invention, such as Figures 1-5 , Figure 8 As shown: The flipping system of the high-density molded sponge composite process includes a composite pretreatment box 1, a pretreatment channel 2 is provided on the composite pretreatment box 1, a conveyor belt 3 is installed through the pretreatment channel 2, and the conveyor belt 3 is used to transport high-density sponge; a flipping frame 4 is installed inside the pretreatment channel 2. The operation of conveyor belt 3 and the technology of conveying high-density sponge by conveyor belt 3 are also existing technologies. They can be purchased directly on the market, assembled by purchasing parts, or learned by consulting journals, etc. Those skilled in the art can choose to purchase them according to their own needs. The operation of conveyor belt 3 and the technology of conveyor belt 3 conveying high-density sponge are not the technology to be protected in this application and will not be described in detail here. The flipping frame 4 includes a pre-treatment frame group one 41, a support and adjustment frame 42, and a pre-treatment frame group two 43. The pre-treatment frame group one 41 and the pre-treatment frame group two 43 are symmetrically distributed. The support and adjustment frame 42 supports the pre-treatment frame group one 41 and the pre-treatment frame group two 43 and can adjust the distance between them. The support and adjustment frame 42 is used to limit the high-density sponge between the pre-treatment frame group one 41 and the pre-treatment frame group two 43 from both sides. The support and adjustment frame 42 is mounted on the flipping robotic arm, which periodically flips and shakes the impurities on the high-density sponge (the impurities here mainly refer to the high-density sponge, which is relatively hard and prone to producing debris during the cutting process). Therefore, the conveyor belt 3 transports the high-density sponge that needs to be glued and laminated to the pretreatment channel 2. The robot arm picks up the high-density sponge and puts it between the pretreatment frame group 1 41 and the pretreatment frame group 2 43 that have been opened. Then, the support adjustment frame 42 is used to reduce the distance between the pretreatment frame group 1 41 and the pretreatment frame group 2 43. At the same time, the support adjustment frame 42 limits the high-density sponge between the pretreatment frame group 1 41 and the pretreatment frame group 2 43 from both sides. Pretreatment frame assembly 1 41 and pretreatment frame assembly 2 43 adopt the same structure. Pretreatment frame assembly 2 43 includes a support frame structure 44 and a high-density sponge cleaning head 45. The support frame structure 44 is mounted on the support adjustment frame 42. The high-density sponge cleaning head 45 is slidably mounted on the support frame structure 44. The high-density sponge cleaning head 45 can slide back and forth along the support frame structure 44. The high-density sponge cleaning head 45 includes a tapping dust removal component 46 and a stubborn impurity cleaning component 47. The tapping dust removal component 46 and the stubborn impurity cleaning component 47 are assembled side by side. The tapping dust removal component 46 is used to monitor the stubborn impurities of residual non-polar release agent or oil stains during the tapping dust removal process of the high-density sponge, and the stubborn impurity cleaning component 47 is used for targeted removal. Therefore, after the high-density sponge is positioned between the pretreatment frame group 1 41 and the pretreatment frame group 2 43, the high-density sponge cleaning head 45 will use the tapping dust removal component 46 to tap and remove dust from the high-density sponge during the back-and-forth sliding process along the support frame structure 44, while simultaneously monitoring for stubborn impurities such as residual non-polar release agent or oil stains. If stubborn impurities such as residual non-polar release agent or oil stains are detected at a certain point on the high-density sponge, the stubborn impurity cleaning component 47 will be used for targeted removal.

[0019] In summary, conveyor belt 3 transports the high-density sponge to be glued and laminated into the pretreatment channel 2. A robotic arm picks up the high-density sponge and places it between the already opened pretreatment frame group one 41 and pretreatment frame group two 43. Then, the support adjustment frame 42 reduces the distance between pretreatment frame group one 41 and pretreatment frame group two 43, while simultaneously limiting the high-density sponge's position between them from both sides. The high-density sponge cleaning head 45 moves along the support frame... During the reciprocating sliding process of structure 44, the high-density sponge is tapped and dusted by the dust removal component 46. At the same time, the stubborn impurities of residual non-polar release agent or oil stains are monitored. After the stubborn impurities of residual non-polar release agent or oil stains are detected in a certain place of the high-density sponge, the stubborn impurity cleaning component 47 is used to remove them at the point. This achieves precise removal of the stubborn impurities of residual non-polar release agent or oil stains by solvent, ensuring that the stubborn impurities of non-polar release agent or oil stains are removed while avoiding solvent residue. It overcomes the problem that non-polar release agents (such as silicone oil) or oil stains are easily left in the production process of high-density sponge. If you simply use the existing technology of ion air gun and cleaning cloth, it is difficult to remove them. Or, simple solvent wiping may result in uneven wiping or improper control of the amount used, causing solvent residue to affect the adhesion.

[0020] In another embodiment of the present invention, such as Figures 8-11 As shown: The two ends of the tapping dust removal component 46 are mounted on the support frame structure 44. The tapping dust removal component 46 includes: Support beam 1461; Two mounting plates 464 are distributed at the ends of the support beam 461; the two mounting plates 464 and the support beam 461 are on the same straight line; Multiple electric telescopic rods 462 are arrayed on the wedge-shaped surface 466 of the supporting beam 461; the wedge-shaped surface 466 is formed on the front end surface of the supporting beam 461. Multiple striking balls 463 are arranged in a one-to-one correspondence with multiple electric telescopic rods 462; the striking balls 463 are fixed at the ends of the electric telescopic rods 462 away from the supporting crossbeam 461. A dust extraction port 465 is provided on a support beam 461; the dust extraction port 465 is connected to a vacuum cleaner via a connecting hose.

[0021] The operation of the vacuum cleaner and the technology of the vacuum cleaner driving the suction port 465 are also existing technologies. They can be purchased directly on the market, assembled by purchasing parts, or learned by consulting journals, etc. Those skilled in the art can choose to purchase them according to their own needs. The operation of the vacuum cleaner and the technology of the vacuum cleaner driving the suction port 465 are not the technologies to be protected in this application, and will not be described in detail here.

[0022] Therefore, during its movement, the tapping dust removal component 46 uses multiple electric telescopic rods 462 to periodically extend and retract, driving the tapping ball 463 to tap the high-density sponge. This removes debris that is easily stuck or clumps together during cutting (mainly because the high-density sponge is relatively hard, and debris from splashes easily sticks to stains or gets stuck on the high-density sponge) from the high-density sponge, allowing for rapid removal via the vacuum cleaner's suction port 465. This solves the problem of debris sticking and getting stuck due to the hard and brittle texture of the high-density sponge. The vibration generated by the tapping loosens and dislodges deep debris, preparing for subsequent deep cleaning, and works in conjunction with the suction port to achieve initial cleaning.

[0023] In another embodiment of the present invention, the supporting beam 461 is equipped with a sensor for detecting non-polar release agents or oil stains at its front end. The sensor includes an ultraviolet fluorescence sensor and an infrared sensor. The ultraviolet fluorescence sensor uses ultraviolet light of a specific wavelength to irradiate the oil stains and release agents, which are excited to produce fluorescence. The non-polar release agent or oil stains are detected by detecting the fluorescence intensity. The infrared sensor analyzes the characteristic absorption of chemical bonds, including CH bonds, in specific infrared bands in the oil stains and release agents.

[0024] In another embodiment of the present invention, such as Figure 12 and Figure 13 As shown: The stubborn impurity cleaning component 47 includes: The horizontal adjustment bracket 471 is installed on the impact dust removal component 46 (specifically, the horizontal adjustment bracket 471 is installed on the support beam 461). The fixed-point cleaning component 472 is slidably mounted on the transverse adjustment frame 471; The lateral adjustment bracket 471 includes: Support beam 2 4711 is added to the impact dust removal component 46; The guide plate 4713 is distributed along the second support beam 4711 and is integrally fixed with the second support beam 4711; A guide groove 4712 is formed on the guide plate 4713; the guide groove 4712 is distributed along the guide plate 4713; a pneumatic telescopic rod is fixed on the guide groove 4712. The guide slider 4714 is slidably mounted on the guide groove 4712; one end of the pneumatic telescopic rod acts inside the guide groove 4712, and the other end acts on the guide slider 4714; the position of the guide slider 4714 on the guide groove 4712 is adjusted by the pneumatic telescopic rod. The connecting plate 4715 is integrally fixed on the guide slider 4714; the connecting plate 4715 is fixedly connected to the fixed-point cleaning component 472.

[0025] Therefore, after the support beam 461 detects stubborn impurities such as residual non-polar release agent or oil stains using an ultraviolet fluorescence sensor or an infrared sensor, it activates the pneumatic telescopic rod. During the extension and retraction of the pneumatic telescopic rod, it drives the guide slider 4714 to move laterally along the guide groove 4712 on the support beam 4711, delivering the fixed-point cleaning component 472 to the location of the residual non-polar release agent or oil stains. The stubborn impurity cleaning component 47 is used for targeted removal, achieving precise removal of stubborn impurities such as residual non-polar release agent or oil stains using solvent. This ensures the removal of stubborn impurities such as non-polar release agent or oil stains while avoiding solvent residue.

[0026] In another embodiment of the present invention, such as Figure 14 and Figure 15 As shown: The fixed-point cleaning component 472 includes: The support platform 473 is fixed to the connecting plate 4715 by a hydraulic cylinder; A fixed-point cleaning tray 476 is assembled at one end of the support platform 473; Vacuum recovery tray 475 is mounted on the other end of support platform 473 away from the fixed cleaning tray 476; A guide column 474 is mounted on a support platform 473. The guide column 474 has a suction hole and a feed hole. One end of the suction hole is connected to a vacuum recovery plate 475, and the other end is connected to a solvent vacuum extraction device through a connecting hose 2. One end of the feed hole is connected to a fixed-point cleaning plate 476, and the other end is connected to a solvent supply device through a connecting hose 3 (the solvent supply device is existing technology, for example, it can be a combination of a storage tank and a liquid pump, the liquid pump takes the solvent out of the storage tank and then supplies it to the feed hole through the connecting hose 3).

[0027] Among them, the solvent vacuum extraction equipment can be an oil-free diaphragm vacuum pump. Oil-free diaphragm vacuum pumps are existing technology. They can be purchased directly on the market, assembled by purchasing parts, or learned about by consulting journals, etc. They are not the technology to be protected in this application and will not be described in detail here. The solution can be D-limonene, or an isoalkane solvent, or a combination of D-limonene and isopropanol, etc. There are no restrictions on the type; those skilled in the art can choose any solution according to their needs.

[0028] In another embodiment of the present invention, such as Figure 15 and Figure 17 As shown: The fixed-point cleaning tray 476 includes: Rotary disk 2 4761 is connected to motor 2 via a combination of rotating tube 2 and rack ring 2 for power transmission; one end of rotating tube 2 is located on the columnar center line of rotary disk 2 4761, and the other end is rotatably connected to connecting tube 2 via sealed bearing ring 2, and connecting tube 2 is connected to the feed hole; rack ring 2 is sleeved on the outside of rotating tube 2 body, and rack ring 2 is connected to motor 2 for power transmission via drive gear 2; Wedge block 2 4764 is integrally fixed on rotating disk 2 4761; Wedge block 3 4766 is integrally fixed on rotating disk 2 4761; Among them, wedge block two 4764 and wedge block three 4766 are distributed in a straight line. Both wedge block two 4764 and wedge block three 4766 are provided with arc-shaped inclined surfaces 4762. The arc-shaped inclined surfaces 4762 of wedge block two 4764 and wedge block three 4766 face opposite directions to ensure uniformity of direction during rotation. Multiple solvent outlet holes 4763 are opened on the arc-shaped inclined surfaces 4762 of wedge block two 4764, and all the multiple solvent outlet holes 4763 are connected to the rotating tube two. Multiple brush strips 4765 are fixed on the arc-shaped inclined surfaces 4762 of wedge block three 4766.

[0029] Therefore, after the support beam 461 detects stubborn impurities such as residual non-polar release agent or oil stains using an ultraviolet fluorescence sensor or infrared sensor, the pneumatic telescopic rod is activated. During the extension and retraction of the pneumatic telescopic rod, the guide slider 4714 moves laterally along the guide groove 4712 on the support beam 4711, delivering the fixed-point cleaning component 472 to the location of the residual non-polar release agent or oil stains. The hydraulic cylinder lowers the vacuum recovery disc 475 and the fixed-point cleaning disc 476 to the location of the non-polar release agent or oil stains on the high-density sponge. The motor 2 starts, and through the power transmission cooperation of the rack ring 2 and the drive gear 2, the power is transmitted to the rotating tube 2 and the rotating disc 4761, causing them to rotate. The second disk 4761 drives the second wedge block 4764 and the third wedge block 4766 to rotate synchronously. The second wedge block 4764 releases solvent through multiple solvent outlet holes 4763 on its arc-shaped inclined surface 4762. After the solvent comes into contact with the non-polar release agent or oil stains, multiple brush strips 4765 on the arc-shaped inclined surface 4762 of the third wedge block 4766 clean it, promoting the contact and mixing of the solvent with the non-polar release agent or oil stains. The stubborn impurity cleaning part 47 is used to perform targeted cleaning, realizing the precise use of solvent to remove stubborn impurities of residual non-polar release agent or oil stains. This ensures that the stubborn impurities of non-polar release agent or oil stains are removed while avoiding solvent residue.

[0030] In another embodiment of the present invention, such as Figure 15 and Figure 16 As shown: The vacuum recovery disc 475 includes: Rotary disk 4751 is connected to motor 1 via a combination of rotating tube 1 and rack ring 1 for power transmission; one end of rotating tube 1 is located on the columnar center line of rotary disk 4751, and the other end is rotatably connected to connecting tube 1 via sealing bearing ring 1, connecting tube 1 is connected to the material extraction hole; rack ring 1 is fitted outside the main body of rotating tube 1, and rack ring 1 is connected to motor 1 via a drive gear 1 for power transmission. Multiple wedge-shaped blocks 4752 are arranged in a ring array on a rotating disk 4751; the wedge-shaped blocks 4752 are integrally fixed on the rotating disk 4751, and multiple vacuum adsorption holes 4753 are opened on the wedge-shaped blocks 4752, all of which are connected to the rotating tube. The vacuum adsorption tube 4754 is assembled on the columnar centerline of the rotating disk 4751; the vacuum adsorption tube 4754 is connected to the rotating disk 4751.

[0031] Therefore, after the support beam 461 detects stubborn impurities such as residual non-polar release agent or oil stains using an ultraviolet fluorescence sensor or infrared sensor, the pneumatic telescopic rod is activated. During the extension and retraction of the pneumatic telescopic rod, the guide slider 4714 moves laterally along the guide groove 4712 on the support beam 4711, delivering the fixed-point cleaning component 472 to the location of the residual non-polar release agent or oil stains. The hydraulic cylinder lowers the vacuum recovery disc 475 and the fixed-point cleaning disc 476 to the location of the non-polar release agent or oil stains on the high-density sponge. The motor 2 starts, and through the power transmission cooperation of the rack ring 2 and the drive gear 2, the power is transmitted to the rotating tube 2 and the rotating disk 4761. The rotating disk 4761 drives the wedge block 4764 and the wedge block 4766 to rotate synchronously. The wedge block 4764 utilizes its arc-shaped inclined surface 4762 to open Multiple solvent outlet holes 4763 are provided to release solvent. After the solvent comes into contact with the non-polar release agent or oil stains, multiple brush strips 4765 on the arc-shaped inclined surface 4762 of the wedge block 4766 clean it, promoting the contact and mixing of the solvent with the non-polar release agent or oil stains. The stubborn impurity cleaning component 47 is used to perform targeted removal, realizing the precise use of solvent to remove stubborn impurities such as residual non-polar release agent or oil stains. When the motor is started, the power is transmitted to the rotating tube 4751 through the power transmission cooperation of the rack ring 4752 and the drive gear 4753. The rotating disk 4751 uses multiple vacuum adsorption holes 4753 on multiple wedge blocks 4752 to squeeze and vacuum separate the solvent and stubborn impurities from the high-density sponge, which can ensure the removal of stubborn impurities such as non-polar release agent or oil stains while avoiding solvent residue.

[0032] Point cleaning disc 476: This is an active, multi-functional solvent application and stirring mechanism; it does not simply spray solvent, but drives wedge block 4764 and wedge block 4766 through rotating disc 2 4761 to simultaneously complete two actions: precise release of solvent and mechanical cleaning with a brush; this greatly promotes the contact, mixing and chemical reaction efficiency between solvent and stubborn dirt, and achieves the synergy of "chemical dissolution" and "physical grinding".

[0033] Vacuum recovery disc 475: This is a synchronous vacuum recovery and squeezing mechanism that intervenes immediately after the rotating disc 4751 starts working. As the multiple wedge blocks 4752 on it rotate, the vacuum suction holes and vacuum suction tubes 4754, along with the physical structure, squeeze the sponge surface while simultaneously suctioning it out. This ensures that waste solvents containing dissolved dirt can be quickly extracted from the inside of the sponge and recovered, rather than left to remain or seep deeper.

[0034] In another embodiment of the present invention, such as Figures 5-7 As shown: The support frame structure 44 includes: Support frame 441 is mounted on support adjustment bracket 42; Two sets of drive rails 442 are symmetrically distributed on the support frame 441; each set of drive rails 442 consists of two rails, which are arranged in parallel. The drive track 442 includes: The guide plate 446 is integrally fixed to the support frame 441; The drive slots are formed on the guide plate 446 and distributed along the main body direction of the guide plate 446; The lead screw 447 is rotatably assembled inside the drive groove and distributed along the main body direction of the drive groove; A drive slider 444 is slidably mounted on a drive groove; the drive slider 444 is sleeved on the lead screw 447 and is threadedly connected to the lead screw 447. The support column 445 is fixed at one end to the drive slider 444 and at the other end to the end of the striking dust removal component 46 (specifically, it is fixed to the mounting plate 464). The drive motor 443 is fixed at the end of the guide plate 446 and is connected to the end of the lead screw 447 that rotates through the drive groove for power transmission.

[0035] Therefore, the drive motor 443 is activated. Through the threaded transmission between the lead screw 447 and the drive slider 444, the drive motor 443 adjusts the longitudinal movement of the dust removal component 46 and the stubborn impurity cleaning component 47, thus delivering the vacuum recovery disc 475 and the fixed-point cleaning disc 476 longitudinally. Simultaneously, the combined pneumatic telescopic rod extends and retracts, driving the guide slider 4714 to move laterally along the guide groove 4712 on the second support beam 4711, thus delivering the vacuum recovery disc 475 and the fixed-point cleaning disc 476 laterally. This ensures that the vacuum recovery disc 475 and the fixed-point cleaning disc 476 are precisely delivered above the location of residual non-polar release agent or oil stains, and the hydraulic cylinder then vacuums the recovery disc. The disc 475 and the fixed-point cleaning disc 476 are placed on the location of the non-polar release agent or oil stains on the high-density sponge, enabling accurate three-dimensional delivery. This facilitates the precise use of solvents to remove stubborn impurities such as residual non-polar release agents or oil stains. Equipped with an ultraviolet fluorescence sensor or an infrared sensor, it can accurately identify non-polar release agents or oil stains that are difficult to detect by ordinary cleaning methods without contact. Once a contaminant is detected, a three-dimensional precision moving platform (consisting of longitudinal movement controlled by the drive motor 443 and the lead screw 447, lateral movement controlled by the pneumatic telescopic rod and the guide groove 4712, and vertical movement controlled by the hydraulic cylinder) is immediately activated to precisely deliver the end effector directly above the contamination point.

[0036] In another embodiment of the present invention, such as Figure 3 and Figure 18 As shown: The support adjustment frame 42 includes: U-shaped support plate 421, which is installed on the flipping robotic arm; Two parallel support strips 422 are correspondingly mounted on the U-shaped support plate 421; multiple mechanical grippers are provided on the support strips 422. Multiple hydraulic telescopic rods 423 are distributed at the ends of the support strip 422; one end of each hydraulic telescopic rod 423 is fixed to the support strip 422, and the other end is fixed to the support frame structure 44.

[0037] Therefore, by extending and retracting the hydraulic telescopic rod 423, the distance between the first pretreatment frame 41 and the second pretreatment frame 43 can be adjusted; the support plate 422 limits the high-density sponge between the first pretreatment frame 41 and the second pretreatment frame 43 from both sides through multiple mechanical grippers.

[0038] In summary: 1. Addressing the issue that vigorous scrubbing or soaking of high-density sponges can damage their pore structure, while simple wiping fails to clean the interior; the tapping dust removal component 46 of this application loosens debris through vibration, avoiding damage to the surface caused by vigorous scraping; the brush strips 4765 of the fixed-point cleaning disc 476 perform localized fine cleaning only on the soiled areas, rather than large-area rough friction; the vacuum recovery disc 475 extracts the waste liquid through negative pressure, rather than rinsing with water, which would allow solvents and dirt to penetrate deep into the sponge; thus, it achieves efficient removal of stubborn dirt while maximizing the protection of the physical structure and integrity of the high-density sponge itself.

[0039] Second, the biggest challenge after using solvents to remove oil stains is solvent residue. This residual solvent itself becomes a new contaminant, affecting subsequent bonding or lamination processes. The vacuum recovery tray 475 and the fixed-point cleaning tray 476 of this application work together. Instead of spraying solvent and waiting for it to evaporate, they immediately "grab" and recover the solvent along with the dissolved dirt from the substrate the moment the solvent has completed its dissolution task. This not only solves the original oil stain problem, but also efficiently solves the solvent residue problem, achieving true cleaning rather than "contamination replacement," and providing an extremely clean surface for subsequent processes. Third, traditional cleaning methods often consume large amounts of solvent or water and generate a large amount of wastewater that needs to be treated; this application uses precise and targeted solvent application, keeping the amount used to a minimum; at the same time, the vacuum recovery disc 475 can recover most of the used solvent, which can be recycled after treatment; thus, it has become a highly efficient, environmentally friendly and energy-saving device, which significantly reduces the chemical consumption and waste liquid treatment costs in the production process. Fourth, it integrates multiple functions such as macroscopic physical impaction, microscopic chemical dissolution, mechanical scrubbing to aid dissolution, and vacuum negative pressure recovery into one device, which can solve various pollution problems from solid debris to stubborn oil stains in one process; the modules are not simply stacked up, but are organically combined through intelligent detection and precise positioning, which produces a synergistic effect and the overall efficiency is far higher than that of step-by-step processing.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
