Description

Technical Field

[0001] The invention relates to the technical field of automated production of foamed silicone rubber, and in particular to automatic dust removal and re-inspection equipment for foamed silicone rubber coils. Background Art

[0002] In modern industrial production, foamed silicone rubber is widely used in aerospace, automobile manufacturing, electronic appliances, building sealing and many other fields due to its unique properties, such as excellent high temperature resistance, chemical corrosion resistance, good elasticity and cushioning performance. As various industries continue to increase their requirements for foamed silicone rubber product quality and production efficiency, traditional production testing methods have gradually exposed many drawbacks.

[0003] For example, when foamed silicone rubber is used in new energy vehicles, the surface of the foamed silicone rubber sheet is required to be free of dust, impurities, and oily fingerprints. However, in the actual production, preparation and transportation of foamed silicone rubber, fingerprints and other impurities are inevitably formed on the surface of the foamed silicone rubber due to the operating environment and the sweat of the operators, resulting in the foamed silicone rubber being unqualified before leaving the factory. Therefore, in the actual production process, the foamed silicone rubber needs to undergo surface inspection and dust removal before leaving the factory, and the inspectors must remove impurities, fingerprints, etc. on the surface of the foamed silicone rubber.

[0004] However, the existing inspection and dust removal method is to manually lay out the rolled foamed silicone rubber on the inspection table, and then manually clean and inspect it bit by bit, which is time-consuming and labor-intensive. In addition, the weight of a roll of foamed silicone rubber ranges from 20 to 40 kg. The labor intensity of inspectors when laying out and rolling up the foamed silicone rubber is high, especially when rolling up, the foamed silicone rubber adheres to the platform surface, and the rolling operation is very difficult.

[0005] In view of this, there is an urgent need for an automatic dust removal and re-inspection equipment for foamed silicone rubber coils and an efficient and accurate method of using it. This equipment needs to be able to achieve fully automated operations from material cleaning, transportation to winding, improve production efficiency and product quality stability, while reducing labor costs and energy consumption, and reducing adverse impacts on the environment. Summary of the invention

[0006] In view of the existing technical problems, the present invention aims to provide an automatic dust removal and re-inspection equipment for foamed silicone rubber coils. Through the cleaning device, conveyor line and winding device arranged on the frame, the automatic connection of the foamed silicone rubber inspection and cleaning process is realized. In terms of usage, the equipment realizes automatic control of the process from material loading, cleaning, conveying to winding through a series of precise operating procedures, which not only reduces manual intervention and reduces product quality differences caused by human factors, but also improves production efficiency and meets the needs of large-scale and high-quality production. At the same time, the overall design of the equipment fully considers energy utilization efficiency, reduces energy consumption while ensuring production performance, and is in line with the current concept of green production.

[0007] To achieve the above object, the present invention provides the following technical solutions: An automatic dust removal and re-inspection device for foamed silicone rubber coils, comprising a frame and: A cleaning device, a conveying device, a winding device and a visual inspection device are arranged on the frame, wherein the cleaning device and the winding device are arranged at two ends of the frame in the length direction, the conveying device is located between the cleaning device and the winding device, the visual inspection device is located at the winding device, and the visual inspection device is respectively located above and below the conveying path of the conveying device; After unwinding, the foamed silicone rubber coil passes through the gap between the first and second cleaning rollers of the cleaning device, and is pulled by the conveying device to the winding device for winding. The first and second cleaning rollers rotate relative to each other to frictionally clean the upper and lower end surfaces of the foamed silicone rubber.

[0008] As an improvement, the first and second erasing rollers are both coated with a cylindrical magic eraser layer, the surface of the magic eraser layer is composed of a plurality of groups of symmetrically arranged friction blocks, and the friction blocks are spirally wound from the axial end of the magic eraser layer to the axial middle of the magic eraser layer to form a V-shaped friction strip.

[0009] As an improvement, a groove is formed between adjacent friction strips, and the groove is connected to the hollow flow channel inside the first or second eliminating roller through the magic eraser layer, the exhaust holes of the first or second eliminating roller, and the hollow flow channel is connected to an external blowing mechanism.

[0010] As an improvement, the V-shaped sharp angle of the friction strip is consistent with the rotation angle direction of the corresponding first eliminating roller or the second eliminating roller.

[0011] As an improvement, the cleaning device also includes a pair of rollers, which are located on the rear side of the first eliminating roller and the second eliminating roller along the unwinding and conveying direction of the foamed silicone rubber. The pair of rollers includes a first row of rollers and a second row of rollers that are arranged to rotate in parallel. The first row of rollers is arranged to be concave in the center, and the second row of rollers is arranged to be convex in the center. After the foamed silicone rubber passes through the gap between the first row of rollers and the second row of rollers, it is conveyed in an upwardly convex arc.

[0012] As an improvement, the cleaning device further comprises a collecting box which is covered outside the first eliminating roller and the second eliminating roller, and the collecting box is connected to the blowing mechanism.

[0013] As an improvement, the cleaning device further comprises a material guide plate disposed between the collecting box and the pair of rollers, and the material guide plate is connected between the end portion at the gap between the pair of rollers and the frame via an elastic member.

[0014] As an improvement, the conveying device includes a clamp and a screw slide group, and the clamp and the screw slide group are symmetrically arranged in two groups. The clamp is installed on the slide of the screw slide group. The clamp clamps the unwinding end of the foam silicone rubber roll and is driven by the screw slide group to transport it to the winding device.

[0015] As an improvement, the winding device includes a vacuum suction cup assembly that is arranged to be lifted and lowered and a rotary pneumatic clamp that is arranged to be telescopic. The vacuum suction cup assembly is arranged above the conveying device, and the rotary pneumatic clamp is symmetrically arranged on both sides of the conveying device. After the vacuum suction cup assembly adsorbs the unwinding end of the foamed silicone rubber roll and lifts it up, the rotary pneumatic clamp clamps the unwinding end of the foamed silicone rubber roll for winding and winding.

[0016] In addition, the present invention also provides a method for using the above-mentioned foamed silicone rubber coil automatic dust removal and re-inspection device, comprising the following steps: Step 1: Preparation: Place the foamed silicone rubber roll to be inspected on a pallet truck, use the pallet truck to transport it to the initial workstation, start the hydraulic lift, lift the foamed silicone rubber roll to the cleaning device, manually guide the foamed silicone rubber through the gap between the first elimination roller and the second elimination roller in sequence, and clamp the unwinding end of the foamed silicone rubber with the conveying device; Step 2: Cleaning of the foamed silicone rubber. Start the cleaning device and the conveying device. When the foamed silicone rubber is pulled by the conveying device, the first removing roller and the second removing roller rotate relatively to clean the surface of the foamed silicone rubber by friction. Step 3: Rewinding and testing. When the foamed silicone rubber is driven by the conveying device to move to the rewinding device, the rewinding device absorbs the unwinding end of the foamed silicone rubber to lift it, and clamps the two sides of the unwinding end of the foamed silicone rubber to rotate and wind it. During the winding process, the visual inspection device inspects the upper and lower end surfaces of the foamed silicone rubber. Step 4: Output: When the foamed silicone rubber is finished rolling up, the rolling device stops working and loosens the foamed silicone rubber roll. If the visual inspection device passes the inspection, the foamed silicone rubber roll is output; Step 5: Re-inspection: if the visual inspection device fails the inspection, the foam silicone rubber roll repeats steps 1 to 4.

[0017] The beneficial effects of the present invention are: (1) The present invention realizes the automatic connection of the inspection and cleaning process of the foamed silicone rubber through the cleaning device, conveying line and winding device arranged on the frame. In terms of the method of use, the equipment realizes the automatic control of the process from material loading, cleaning, conveying to winding through a series of precise operation processes, which not only reduces manual intervention and reduces the product quality differences caused by human factors, but also improves production efficiency and meets the large-scale and high-quality production needs. At the same time, the overall design of the equipment fully considers the energy utilization efficiency, reduces energy consumption while ensuring production performance, and conforms to the current concept of green production; (2) The present invention provides friction strips arranged in a V-shape on the magic eraser layer. This design increases the contact area and friction force between the friction block and the surface of the foamed silicone rubber. The upper and lower magic eraser layers rotate relative to each other and the rotation direction is opposite to the movement direction of the foamed silicone rubber. This enables the friction block to generate stronger friction force when in contact with the foamed silicone rubber, thereby being able to perform friction cleaning on the upper and lower surfaces of the foamed silicone rubber more comprehensively and deeply. In addition, the photo material can effectively remove impurities such as tiny particles, dust, fingerprints, etc. on the surface of the foamed silicone rubber. Compared with the traditional flat roller cleaning method, the cleaning effect is significantly improved. (3) The exhaust holes on the magic eraser layer of the present invention cooperate with the air blowing mechanism. When the friction block cleans the impurities, the air blowing mechanism transports the water vapor into the groove through the pipe through the exhaust holes. The friction block cooperates with the water in the water vapor to remove impurities from the upper and lower surfaces of the foamed silicone rubber, which can effectively remove stains, impurities and fingerprints, etc., and has a good cleaning effect. On the other hand, the water vapor flows along the groove, which can form a water flow to guide the removed impurities into the collection box, so as to achieve better centralized treatment. (4) The present invention further provides a pair of rollers at the tail end of the cleaning device. After the foamed silicone rubber passes through the gap between the pair of rollers, it is conveyed in an upwardly convex arc shape, so that the foamed silicone rubber will not be completely attached to the platform of the frame, and thus when the conveying device pulls the foamed silicone rubber, the conveying device can smoothly drive the foamed silicone rubber to move, and when the winding device is winding, the blowing device will generate airflow upward to lift the foamed silicone rubber, making it easier for the winding device to wind up. When the foamed silicone rubber is conveyed in an arc shape, the wind force output by the blowing device can be caught by the foamed silicone rubber, and the lower end surface of the foamed silicone rubber is prevented from being scratched; (5) The cleaning device, winding device and visual inspection device in the present invention are each provided with two groups, and are symmetrically arranged at both ends of the conveying device, so that after the foamed silicone rubber completes a dust removal inspection, if the inspection result is unqualified, it can be directly unwound, cleaned and wound again from the other end of the conveying device, without the need to transfer the foamed silicone rubber or reset the conveying device, which makes the operation more convenient and efficient.

[0018] In summary, the present invention has the advantages of efficient processing, improved processing efficiency, stability and safety, and convenient operation, and is particularly suitable for the field of automated production technology of foamed silicone rubber.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Embodiment 1: like Figures 1 to 17 As shown, an automatic dust removal and re-inspection device for foamed silicone rubber coils includes a frame 1, and also includes a cleaning device 2, a conveying device 3, a winding device 4 and a visual inspection device 5 installed on the frame 1; The conveying device 3 reciprocates along the length direction of the platform 10 on the frame 1, and the cleaning device 2 can efficiently and quickly clean the upper and lower end surfaces of the unrolled foamed silicone rubber. The reeling device 4 is responsible for neatly and tightly reeling up the cleaned and tested foamed silicone rubber for storage and transportation; The cleaning device 2 is rotatably mounted on the frame 1, and the cleaning device 2 includes a first eliminating roller 21, a second eliminating roller 22 and a blowing mechanism 23. The first eliminating roller 21 and the second eliminating roller 22 are both hollow, and the first eliminating roller 21 is arranged directly above the second eliminating roller 22. The two form an upper and lower relative layout, and can simultaneously clean the upper and lower surfaces of the foamed silicone rubber. The first eliminating roller 21 and the second eliminating roller 22 are driven by a motor, and the first eliminating roller 21 and the second eliminating roller 22 are connected by a gear transmission. One end of the second eliminating roller 22 is connected to the motor. The motor is preferably a high-performance variable frequency speed regulating motor with the characteristics of large torque, wide speed adjustment range and high precision. The first eliminating roller 21 and the second eliminating roller 22 are relatively rotatable. This relative rotation method makes When the foamed silicone rubber passes between the two rollers, it is subjected to uniform friction from both the upper and lower directions, which can more effectively remove impurities on the surface. At the same time, the relative rotation speed difference can also be adjusted according to actual conditions to further enhance the cleaning strength. The blowing mechanism 23 is connected to the first elimination roller 21 and the second elimination roller 22. The blowing mechanism 23 is composed of a bellows 231 and an airflow distribution pipeline 232. The bellows 231 generates high-pressure airflow suction. A water vapor atomization generating device is arranged inside the bellows 231, which can generate a large number of small water droplets. The small water droplets are mixed with the air flow to form a water vapor flow. The water vapor flow passes through the airflow distribution pipeline 232, and the water vapor flow is uniformly transported to the first elimination roller 21 and the second elimination roller 22. The water vapor in the water vapor flow cooperates with the magic eraser layer 211 to remove impurities, stains, and fingerprints on the upper and lower surfaces of the foamed silicone rubber. Specifically, the first erasing roller 21 and the second erasing roller 22 are both coated with a magic eraser layer 211. The magic eraser layer 211 is a part that directly contacts the foamed silicone rubber during the cleaning process. The main component of the material is silicone. Silicone has elastic buffering properties. This elastic property enables it to fit the complex curved surface through moderate compression when it contacts the foamed silicone rubber surface, ensuring sufficient friction to remove surface particle impurities, and avoiding material damage caused by excessive contact. The silicone material itself is a non-polar polymer and has excellent compatibility with the silicone rubber substrate, which can effectively avoid the problem of interface adhesion between the two. Silicone has strong physical adsorption and friction decontamination capabilities. When cleaning the foamed silicone rubber surface, there is no need to add detergent. Just dip it in water and wipe it gently to remove various stains, such as stains, water stains, etc. Its microstructure can be closely combined with impurities, and the impurities are separated from the silicone rubber surface by friction, ensuring effective cleaning of the foamed silicone rubber. Specifically, the first erasing roller 21 and the second erasing roller 22 are both coated with a cylindrical magic eraser layer 211, and the surface of the magic eraser layer 211 is composed of a plurality of groups of symmetrically arranged friction blocks 2111, and the friction blocks 2111 are spirally wound from the axial end of the magic eraser layer 211 to the axial middle of the magic eraser layer 211 to form a V-shaped friction strip 2110.

[0025] Furthermore, grooves 2120 are formed between adjacent friction strips 2110, and the grooves 2120 are connected to the hollow flow channel inside the first eliminating roller 21 or the second eliminating roller 22 through the magic eraser layer 211, the exhaust holes 2112 of the first eliminating roller 21 or the second eliminating roller 22 in sequence, and the hollow flow channel is connected to an external blowing mechanism 23, and the blowing mechanism 23 transports water vapor to the hollow flow channel.

[0026] Furthermore, the V-shaped sharp angle of the friction strip 2110 is consistent with the rotational angular velocity direction of the corresponding first eliminating roller 21 or second eliminating roller 22; The magic eraser layer 211 is provided with a plurality of exhaust holes 2112 in a circumferential array, and the exhaust holes 2112 are arranged between adjacent friction blocks 2111 (i.e., in the groove 2120). When the foamed silicone rubber passes through the gap between the first and second erasing rollers 21 and 22, the friction blocks 2111 on the first and second erasing rollers 21 and 22 rub and clean the upper and lower surfaces of the foamed silicone rubber, and the air blowing mechanism 23 blows the impurities to move to both sides along the arrangement direction of the friction blocks 2111 through a water vapor flow until they fall off. The conveying device 3 drives the foamed silicone rubber to move along the length direction of the frame 1 to below the winding device 4, and the winding device 4 winds and arranges the foamed silicone rubber.

[0027] Furthermore, the first elimination roller 21 and the second elimination roller 22 each include an air pipe 212, which is hollow and penetrates the first elimination roller 21 and the second elimination roller 22. The air pipe 212 is connected to the air blowing mechanism 23 through a pipeline. The two ends of the first elimination roller 21 and the second elimination roller 22 are installed and connected to the frame 1 through a bearing seat, and the magic eraser layer 211 is sleeved on the surface of the first elimination roller 21 and the second elimination roller 22 through a tooth structure. The air delivery pipe 212 is provided with an air blowing groove 2121, and the direction of the air blowing groove 2121 is set at an angle with the axial center line of the air delivery pipe 212. The water vapor flows from the bellows 231 to the air blowing groove 2121 via the air flow distribution pipe 231. When the magic eraser layer 211 rotates, the water vapor flows from the exhaust holes 2112 corresponding to the air blowing groove 211, and cooperates with the V-shaped friction block 2111 to form a collaborative cleaning mechanism. The V-shaped friction block 2111 rubs and cleans the upper and lower surfaces of the foamed silicone rubber. Their V-shaped structure can better guide impurities to gather in a specific direction. At this time, the water vapor discharged from the exhaust hole 2112 can just blow the impurities along the direction guided by the friction block 2111, so as to achieve a more thorough cleaning effect.

[0028] In addition, it should be noted that in order to improve the cleaning effect, a fiber sponge can also be installed on the friction block 2111, that is, 1 / 4 or 1 / 3 of the friction block 2111 is selected, a groove is dug thereon, and the fiber sponge is embedded in the groove. Then, through the good water absorption and flexibility combined with the effect of water vapor, the oil, fingerprints and other impurities on the surface of the foamed silicone rubber can be effectively adsorbed and removed. What's more, the fine fiber structure of the fiber sponge can penetrate into the tiny pores of the silicone rubber and clean out the impurities therein.

[0029] Furthermore, the cleaning device 2 also includes a pair of rollers 24, which are rotatably mounted on the frame 1 through a bearing seat, and the high-precision rolling bearing of the bearing seat is used to ensure that the pair of rollers 24 can rotate steadily and smoothly on the frame 1, reduce friction and mechanical loss during rotation, and ensure long-term stable operation of the equipment. The pair of rollers 24 include a first row of rollers 241 and a second row of rollers 242, the first row of rollers 241 and the second row of rollers 242 are arranged in parallel up and down, the first row of rollers 241 are centrally concave, the second row of rollers 242 are centrally convex, and the concave portion of the first row of rollers 241 and the convex portion of the second row of rollers 242 are correspondingly arranged, when the foamed silicone rubber is eliminated from the first row of rollers 241, the second row of rollers 242 is centrally convex, and the concave portion of the first row of rollers 241 and the convex portion of the second row of rollers 242 are correspondingly arranged. After the preliminary friction and blowing cleaning process is completed between the roller 21 and the second eliminating roller 22, at this time, there is a certain height difference between the output foamed silicone rubber and the roller 24. The blowing device 101 in the platform 10 blows air upward through the ventilation hole 100. The air flow vertically impacts the foamed silicone rubber coming out from between the first eliminating roller 21 and the second eliminating roller 22. Since the foamed silicone rubber itself has a certain flexibility and elasticity, it begins to shake under the continuous impact of the air flow. The shaking helps to further remove the fine impurities remaining on the surface of the foamed silicone rubber. The rotation of the roller 24 and the interaction with the shaking foamed silicone rubber can adjust the flatness of the surface of the foamed silicone rubber and further improve the product quality.

[0030] In addition, a plurality of ventilation holes 100 are provided on the upper and lower surfaces of the platform 10. A plurality of blowing devices 101 are arranged inside the platform 10. When the blowing devices 101 start to work, they generate stable airflows, which are blown vertically upward through the ventilation holes 100 on the upper surface of the platform 10. Due to the force of the airflow, a certain gap is formed between the foamed silicone rubber placed on the platform 10 and the platform 10, thereby avoiding friction damage that may be caused by direct contact between the foamed silicone rubber and the surface of the platform 10. The generation of this gap effectively isolates the direct contact between the two, thereby ensuring the surface integrity of the foamed silicone rubber.

[0031] It should be further explained that the cleaning device 2 also includes a collecting box 25. The main function of the collecting box 25 is to collect various impurities, dust and possible waste removed from the surface of the foamed silicone rubber during the cleaning process, to ensure the cleanliness of the equipment and the hygiene of the working environment, and to facilitate subsequent impurity treatment and cleaning operations. The collecting box 25 is fixedly installed on the frame 1. The collecting box 25 is arranged below the first eliminating roller 21 and the second eliminating roller 22. When the first eliminating roller 21 and the second eliminating roller 22 perform friction cleaning and air blowing cleaning on the foamed silicone rubber, the removed impurities will naturally fall into the collecting box 25 under the action of gravity, thereby achieving effective collection of impurities. The side walls of the collecting box 25 are provided with limiting grooves 250 for accommodating the first eliminating roller 21 and the second eliminating roller 22, so as to ensure the stability of the position between the collecting box 25 and the first eliminating roller 21 and the second eliminating roller 22, avoid horizontal deviation during operation, ensure the sealing performance between the first eliminating roller 21 and the second eliminating roller 22 and the collecting box 25, and prevent impurities from leaking from the gap and affecting the collection effect; The collection box 25 is hingedly provided with a flap 251. This design facilitates manual insertion of the foamed silicone rubber between the first elimination roller 21 and the second elimination roller 22, and secondly facilitates cleaning and maintenance of the collection box 25. The collecting box 25 is provided with a discharge trough 252 on one side facing the pair of rollers 24. The design of the discharge trough 252 enables the foamed silicone rubber to directly enter the subsequent process after completing the cleaning process of the first elimination roller 21 and the second elimination roller 22 without additional transfer or adjustment, which greatly reduces the pause and waiting time in the production process, improves the overall production efficiency, and ensures the continuity of the foamed silicone rubber from cleaning to subsequent processing; The bottom of the collecting box 25 is bucket-shaped. This bucket-shaped structure is for facilitating the gathering and discharge of impurities. During the cleaning process, after the impurities fall into the collecting box 25, they will gradually converge to the center along the bottom of the bucket due to the effect of gravity. A discharge channel 253 is provided at the bottom of the collecting box 25. The discharge channel 253 is connected to an external negative pressure suction dust collection device. The bottom of the collecting box 25 is bucket-shaped. This bucket-shaped structure is for facilitating the gathering and discharge of impurities. During the cleaning process, after the impurities fall into the collecting box 25, they will gradually converge to the center along the bottom of the bucket due to the effect of gravity. The bucket-shaped bottom can also reduce the dead corners of impurity accumulation, ensuring that the impurities can smoothly flow to the discharge channel 253 at the bottom. The discharge channel 253 is connected to an external waste treatment system. A baffle 254 is arranged between the discharge trough 252 and the first eliminating roller 21 and the second eliminating roller 22. The setting of the baffle 254 separates the impurities in the collection box 25 from the cleaned foamed silicone rubber, so as to prevent the cleaned foamed silicone rubber from being contaminated again and affecting the product quality. This also facilitates the maintenance and cleaning of the equipment to a certain extent. When it is necessary to clean the collection box 25, due to the isolation of the baffle 254, the impurities at the bottom can be cleaned more easily without worrying about affecting the transmission of the cleaned foamed silicone rubber. Secondly, the end of the baffle 254 is precisely connected to the entrance of the discharge trough 252. The baffle 254 can enable the foamed silicone rubber to enter the discharge trough 252 accurately under the guidance of the baffle 254 after the foamed silicone rubber is cleaned from the first eliminating roller 21 and the second eliminating roller 22.

[0032] In addition, a guide plate 26 is provided between the first elimination roller 21, the second elimination roller 22 and the pair of rollers 24, one end of the guide plate 26 is connected to the collection box 25, and the guide plate 26 is obliquely extended from the collection box 25 to the pair of rollers 24. This oblique setting meets the transmission requirements of the foamed silicone rubber. After the foamed silicone rubber is cleaned by the first elimination roller 21 and the second elimination roller 22, it can move smoothly toward the pair of rollers 24 along the inclination angle of the guide plate 26 with the help of gravity and its own movement inertia. The guide plate 26 provides a clear and stable path for the transmission of the foamed silicone rubber, avoiding the deviation or scattering of the foamed silicone rubber during the transmission process, and ensuring the continuity and stability of the production process; Specifically, a connecting plate 261 is fixedly connected to one side of the guide plate 26 , and the connecting plate 261 is connected to the frame 1 through an elastic member 262 . The elastic connecting force of the elastic member 262 enables the connecting plate 261 to be suspended on the frame.

[0033] Furthermore, the conveying device 3 includes a clamp 31 and a screw slide group 32. The clamp 31 and the screw slide group 32 are both provided with two groups. The structural design of the clamp 31 fully considers the protection of the foamed silicone rubber. The surface in contact with the foamed silicone rubber is made of soft and wear-resistant material to avoid damage to the surface of the foamed silicone rubber during the clamping process. At the same time, the clamp 31 has sufficient clamping force to ensure that the foamed silicone rubber will not slide or fall off during the conveying process, thereby ensuring the stability and safety of the conveying. The clamp 31 is slidably mounted on both sides of the platform 10 through a slide 33. The slide 33 provides precise guidance and stable support for the movement of the clamp 31, which can effectively reduce the friction resistance of the clamp 31 during movement, making its movement smoother and more stable. At the same time, the rigidity and stability of the slide 33 ensure that the clamp 31 will not shake or deviate when carrying the foamed silicone rubber, further improving the accuracy and reliability of transportation; The clamp 31 is connected to the screw slide group 32, and the screw slide group 32 drives the clamp 31 to move along the length direction of the platform 10 through its own rotation. The screw slide group 32 on one side is driven by a motor, and the screw slide groups 32 on both sides are rotated synchronously through a chain 34, ensuring that the clamps 31 on both sides can move synchronously, ensuring that the foamed silicone rubber remains symmetrical and stable during the transportation process, and avoiding deformation or damage of the foamed silicone rubber due to inconsistent movement on both sides.

[0034] It should be noted that the clamp 31 includes a pneumatic clamp 311, which cooperates with a screw slide group 32 that moves back and forth along the length direction of the platform 10, greatly optimizing the transportation link of the foamed silicone rubber in the entire production process. Through the reciprocating movement of the screw slide group 32, not only the detours and repeated paths of the clamp 31 during transportation are reduced, avoiding unnecessary waste of time, but also the spatial layout of the equipment can be fully utilized, thereby improving the overall production efficiency and ensuring the smoothness and stability of the entire production process.

[0035] Furthermore, the winding device 4 includes a vacuum suction cup assembly 41 and two groups of rotating pneumatic clamps 42, the vacuum suction cup assembly 41 is installed on the frame 1, the vacuum suction cup assembly 41 is arranged above the platform 10, a lifting assembly is arranged between the vacuum suction cup assembly 41 and the frame 1, the vacuum suction cup assembly 41 moves up and down perpendicular to the platform 10 through the lifting assembly, and its main function is to use vacuum suction to perform preliminary positioning and gripping of the foamed silicone rubber, ensuring that the foamed silicone rubber is in the correct starting position, and preparing for the subsequent winding operation. When the vacuum suction cup assembly 41 is started, a vacuum area is formed through the exhaust system, and a pressure difference is generated between the suction cup and the surface of the foamed silicone rubber, so that the foamed silicone rubber is firmly sucked. This working principle can avoid physical damage to the surface of the foamed silicone rubber, because compared with the traditional mechanical clamping method, the vacuum adsorption method will not directly squeeze or scratch the foamed silicone rubber; The rotating pneumatic clamp 42 is installed on the frame 1. The rotating pneumatic clamp 42 can stably clamp and rotate the foamed silicone rubber, drive the foamed silicone rubber to wind around the winding center, and ensure that the foamed silicone rubber can be evenly and tightly wound on the component. The rotating pneumatic clamp 42 is composed of a clamp unit 421 and a rotating motor 422. The rotating motor 422 drives the clamp unit 421 to rotate; The tail of the rotating pneumatic clamp 42 is provided with a telescopic element 43, and the telescopic element 43 drives the rotating pneumatic clamp 42 to approach one side of the platform 10. The telescopic element 43 is preferably a cylinder, which can accurately control the telescopic stroke and speed of the rotating pneumatic clamp 42, thereby realizing the effective clamping and winding operation of the foamed silicone rubber of different specifications and lengths; During the winding process, the vacuum suction cup assembly 41 will first descend to a suitable position, absorb the foamed silicone rubber transmitted from the conveying device 3, lift it and position it to the starting position of winding, and then the telescopic element 43 will drive the rotating pneumatic clamp 42 to approach the foamed silicone rubber, and the rotating pneumatic clamp 42 will clamp the foamed silicone rubber. Once the rotating pneumatic clamp 42 clamps the foamed silicone rubber, the vacuum suction cup assembly 41 can release the foamed silicone rubber, and the rotating pneumatic clamp 42 starts to rotate, driving the foamed silicone rubber to be wound. After the winding is completed, the position of the rotating pneumatic clamp 42 is adjusted by the telescopic element 43 to restore it to the initial position.

[0036] Embodiment 2: like Figures 1 to 17 As shown, the present invention also provides a method for using the foamed silicone rubber coil automatic dust removal and re-inspection device described in Example 1, comprising the following steps: Step 1: Preparation: Place the foamed silicone rubber roll to be inspected on a flatbed truck, use the flatbed truck to transport it to the initial workstation, start the hydraulic lift, lift the foamed silicone rubber roll to the outer side of the collection box, and the worker manually guides the foamed silicone rubber through the gap between the first elimination roller 21 and the second elimination roller 22, as well as the gap between the rollers 24. After the insertion is completed, one end of the foamed silicone rubber is connected to the clamp 31 to achieve the initial positioning of the foamed silicone rubber; Step 2: Cleaning the foamed silicone rubber. Start the cleaning device 2 and the conveying device 3. When the foamed silicone rubber is pulled by the conveying device 3, the foamed silicone rubber passes through the first removing roller 21 and the second removing roller 22. At this time, the first removing roller 21 and the second removing roller 22 rotate relatively, and use the friction blocks 2111 on the magic eraser layer 211 to rub and clean the surface of the foamed silicone rubber. At the same time, the air blowing mechanism 23 works to blow the impurities to move to both sides along the arrangement direction of the friction blocks 2111 until the impurities fall into the bottom collection box 25. Step 3: Transfer and sorting of foamed silicone rubber. When the foamed silicone rubber is moved to the winding station driven by the clamp 31, the vacuum suction cup assembly installed on the frame generates sufficient suction to suck the foamed silicone rubber from the clamp 31. Then, under the traction of the vacuum suction cup assembly, the foamed silicone rubber is moved to the winding station. At the winding station, the rotating pneumatic clamps 42 arranged on both sides start to work to firmly clamp the two sides of the foamed silicone rubber. After the clamping operation is completed, the rotating pneumatic clamps 42 start to rotate. At the same time, the visual inspection devices 5 located above and below the winding station synchronously inspect the foamed silicone rubber roll. Step 4: When the foamed silicone rubber is finished rolling up, the rolling device 4 stops working, and the pneumatic clamping claw 42 is rotated to loosen the foamed silicone rubber roll. After the inspection is qualified, the foamed silicone rubber roll is transferred to the cart through the inclined platform for output; Step 5: If the test fails, the foamed silicone rubber roll is transferred to a pallet truck via an inclined platform, and the above steps 1 to 4 are repeated to clean and test again.

[0037] Furthermore, in step two, the rotation direction of the first eliminating roller 21 and the second eliminating roller 22 is opposite to the transport direction of the conveying device 3, and the rotation direction of the first eliminating roller 21 and the second eliminating roller 22 is the same as the direction of the friction block 2111, so that the friction block 2111 can contact the surface of the foamed silicone rubber more accurately and stably when rotating. When the foamed silicone rubber moves forward driven by the conveying device 3, the first eliminating roller 21 and the second eliminating roller 22 rotate in the opposite direction and cooperate with the friction block 2111 to enhance the cleaning effect on the foamed silicone rubber and ensure that the surface cleanliness of the foamed silicone rubber meets the standards before entering the subsequent process.

[0038] Furthermore, in the step 2, the width of the magic eraser layer 211 is D1, and the width of the foamed silicone rubber is D2, satisfying the condition: D1>D2. If the widths of the magic eraser layer 211 and the foamed silicone rubber are equal, the cleaned impurities are likely to stay at the edge of the foamed silicone rubber due to insufficient space, and may even be attached to the foamed silicone rubber again due to subsequent operations, affecting the cleaning effect. However, when the width D1 of the magic eraser layer 211 is greater than the width D2 of the foamed silicone rubber, a buffer zone is formed on both sides of the foamed silicone rubber, and the impurities can easily fall from the buffer zone after being removed.

[0039] Furthermore, in step three, in terms of appearance, the visual inspection device 5 scans the surface of the material roll through the industrial camera imaging system to accurately identify whether there are scratches, bubbles, impurities and other defects. In terms of performance parameter detection, it uses the built-in laser sensor to accurately measure the thickness, width and length parameters of the foamed silicone rubber material roll. The visual inspection device 5 will transmit the collected data information to the control system, and the control system will quickly analyze and process the data to determine whether the foamed silicone rubber material roll meets the quality requirements.

[0040] Specifically, the visual inspection device 5 located at the top is installed and connected to the vacuum suction cup assembly 41, while the visual inspection device 5 located at the bottom is embedded in the conveying device 3. The upper and lower groups of visual inspection devices 5 respectively inspect the upper and lower end surfaces of the foamed silicone rubber.

[0041] In addition, it should be noted that in order to improve the efficiency of detection and cleaning, two groups of cleaning devices 2 and winding devices 4 are provided in the present application, and the two groups of cleaning devices 2 and winding devices 4 are respectively arranged at the two ends of the conveying device 3, and the clamp 31 of the conveying device 3 is also provided with two groups of pneumatic clamps 311, and the clamps 311 on both sides are arranged in opposite directions. This means that after the conveying device 3 conveys the foamed silicone rubber to the winding device 4 on one side, the conveying device 3 does not need to return, and can directly perform the next cleaning work through the cleaning device 2 on that side.

[0042] It should be further explained that after setting up two groups of cleaning devices 2 and winding devices 4, in step four, when the rotating pneumatic clamp 42 clamps the foamed silicone rubber for winding, the guide plate 26 set on the cleaning device 2 on the same side will contact the foamed silicone rubber roll rolled up by the winding device 4, so that the foamed silicone rubber roll can always be in a good rolled state, and the elastic member 262 set on the guide plate 26 will provide a compressive elastic force to the guide plate 26, so that the foamed silicone rubber roll can be in a tight rolled state.

[0043] Specifically, an elastic member 262 is provided between the connecting plate 261 and the frame 1, and the elastic member 262 is preferably a spring. The guide plate 26 is arranged to float up and down along the longitudinal direction of the frame 1. The thickness, hardness and other characteristics of the foamed silicone rubber may fluctuate, and the roll diameter will continue to increase during the winding process. The elastic member 262 can automatically adjust the pressure between the connecting plate 261 and the foamed silicone rubber according to these changes. When the foamed silicone rubber is thicker or the roll diameter increases, the elastic member 262 will be compressed to make the connecting plate 261 move up appropriately. The connecting plate 261 maintains a suitable pressure through the compression of the elastic member 262, ensuring that the pressure is always maintained at a level that can effectively compress the foamed silicone rubber. This adaptive adjustment avoids deformation or damage of the foamed silicone rubber due to excessive pressure, and also prevents the pressure from being too small to achieve the compression effect.

[0044] Furthermore, in the step five, the moving direction of the conveying device 3 is opposite to the moving direction of the conveying device 3 in the step one. The reverse movement design makes the entire foamed silicone rubber processing process more coherent and efficient, can better utilize the spatial layout of the equipment, reduce the detours and repeated paths of the foamed silicone rubber during transportation, and improve production efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
