Description

Technical Field

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

[0002] In modern industrial production, foamed silicone rubber is widely used in many fields such as aerospace, automotive manufacturing, electronics and electrical appliances, and building sealing due to its unique properties, such as excellent high-temperature resistance, chemical corrosion resistance, good elasticity and cushioning performance. With the continuous improvement of the quality and production efficiency requirements of foamed silicone rubber products in various industries, many drawbacks of traditional production and inspection methods have gradually emerged.

[0003] For example, when foamed silicone rubber is used in new energy vehicles, it is required that the surface of the foamed silicone rubber sheet is free of dust and impurities and oil film fingerprints. However, in the actual production, preparation and transportation process of foamed silicone rubber, due to factors such as the operating environment and the sweat of operators, it is inevitable to form fingerprints and other impurities on the surface of the foamed silicone rubber, resulting in unqualified products when leaving the factory. Therefore, in the actual production process, the surface of the foamed silicone rubber needs to be inspected and dusted before leaving the factory, and the inspectors need to remove impurities, fingerprints, etc. on the surface of the foamed silicone rubber.

[0004] However, the existing inspection and dust removal method is to manually flatten the rolled foamed silicone rubber on the inspection table and then clean and inspect it bit by bit manually, which is time-consuming and laborious. Moreover, the mass of a roll of foamed silicone rubber ranges from 20 to 40 kg, and the labor intensity of the inspectors is high when flattening and rewinding the foamed silicone rubber. Especially when rewinding, the foamed silicone rubber adheres to the platform surface, and the rewinding operation is very difficult.

[0005] In view of this, there is an urgent need for an automatic dust removal and re-inspection device for foamed silicone rubber coils and its efficient and accurate use method. This device needs to be able to realize full-automatic operations from material cleaning, conveying to rewinding, improve production efficiency and product quality stability, while reducing labor costs and energy consumption, and reducing the adverse impact on the environment. Summary of the Invention

[0006] In response to 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 through a series of precise operating processes, from material loading, cleaning, conveying to winding. It 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, 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:

[0008] An automatic dust removal and re-inspection device for a foamed silicone rubber coil comprises a frame and:

[0009] 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 respectively arranged at the two ends of the frame in the length direction, the conveying device is located between the cleaning device and the winding device, and the visual inspection device is located at the winding device. The visual inspection device is respectively located above and below the conveying path of the conveying device;

[0010] After unwinding, the foamed silicone rubber roll passes through the gap between the first eliminating roller and the second eliminating roller of the cleaning device, and is pulled by the conveying device to the winding device for winding. The first eliminating roller and the second eliminating roller rotate relative to each other to rub and clean the upper and lower end surfaces of the foamed silicone rubber.

[0011] As an improvement, the first and second erasing rollers are both covered with a cylindrical magic eraser layer, the surface of which is composed of a plurality of symmetrically arranged friction blocks, which spirally wrap 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.

[0012] As an improvement, grooves are formed between adjacent friction strips, and the grooves are connected to the hollow flow channel inside the first eliminating roller or the second eliminating roller through the magic eraser layer, the exhaust holes of the first eliminating roller or the second eliminating roller in sequence, and the hollow flow channel is connected to an external blowing mechanism.

[0013] 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.

[0014] As an improvement, the cleaning device further includes a pair of rollers. Along the unwinding and conveying direction of the foamed silicone rubber, the pair of rollers is located at the rear side of the first elimination roller and the second elimination roller. The pair of rollers includes a first row of rollers and a second row of rollers that are rotatably arranged in parallel. The first row of rollers is arranged with a central depression, and the second row of rollers is arranged with a central protrusion. 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 upward convex arc shape.

[0015] As an improvement, the cleaning device further includes a collection box covering the outside of the first elimination roller and the second elimination roller, and the collection box is communicated with the air blowing mechanism.

[0016] As an improvement, the cleaning device further includes a guide plate arranged between the collection box and the pair of rollers. The end of the guide plate connecting the gap of the pair of rollers and the frame is connected by an elastic member.

[0017] As an improvement, the conveying device includes a fixture and a lead screw sliding table group. There are two groups of the fixture and the lead screw sliding table group symmetrically arranged. The fixture is installed on the sliding table of the lead screw sliding table group. The fixture clamps the unwinding end of the foamed silicone rubber roll and is driven by the lead screw sliding table group to be conveyed to the winding device.

[0018] As an improvement, the winding device includes a vacuum suction cup assembly arranged to move up and down and a rotary pneumatic gripper arranged to stretch. The vacuum suction cup assembly is arranged above the conveying device, and the rotary pneumatic grippers are symmetrically arranged on both sides of the conveying device. After the vacuum suction cup assembly adsorbs and lifts the unwinding end of the foamed silicone rubber roll, the rotary pneumatic gripper clamps the unwinding end of the foamed silicone rubber roll for winding and winding.

[0019] In addition, the present invention also provides a use method of the automatic dust removal and re-inspection equipment for the foamed silicone rubber coil material described above, including the following steps:

[0020] Step 1: Preparation work. Place the foamed silicone rubber coil to be inspected on a flatbed cart, use the flatbed cart to transport it to the initial station, start the hydraulic lift, lift the foamed silicone rubber coil to the cleaning device, and 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 by the conveying device;

[0021] 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 relatively rotating first elimination roller and the second elimination roller clean the surface of the foamed silicone rubber by friction;

[0022] Step 3: Rewinding and inspection. When the foamed silicone rubber moves to the rewinding device driven by the conveying device, the rewinding device adsorbs the unwinding end of the foamed silicone rubber to lift it, and clamps both sides of the unwinding end of the foamed silicone rubber to rotate and wind. During the winding process, the visual inspection device inspects the upper and lower end faces of the foamed silicone rubber;

[0023] Step 4: Output. When the rewinding of the foamed silicone rubber is completed, the rewinding device stops working and releases the foamed silicone rubber coil. If the visual inspection device detects that it is qualified, the foamed silicone rubber coil is output;

[0024] Step 5: Re-inspection. When the visual inspection device detects unqualified, the foamed silicone rubber coil repeats the operations of Steps 1 to 4.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) Through the cleaning device, conveying line and rewinding device provided on the frame, the present invention realizes the automatic connection of the inspection and cleaning process of the foamed silicone rubber. In terms of the usage method, through a series of precise operation processes, the equipment realizes the automatic control of the process from the feeding, cleaning, conveying to rewinding of the material, which not only reduces manual intervention, reduces the product quality differences caused by human factors, but also improves production efficiency, meets the production requirements of large scale and high quality. At the same time, the overall design of the equipment fully considers the energy utilization efficiency, reduces energy consumption on the premise of ensuring production performance, and conforms to the concept of current green production;

[0027] (2) The present invention arranges friction strips in a V-shaped arrangement 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 groups of magic eraser layers rotate relative to each other and the rotation direction is opposite to the moving direction of the foamed silicone rubber. This enables the friction block to generate a stronger friction force when contacting the foamed silicone rubber, so as to more comprehensively and deeply friction and clean the upper and lower surfaces of the foamed silicone rubber, and the photo material can just effectively remove impurities such as fine 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;

[0028] (3) The exhaust holes on the magic eraser layer of the present invention cooperate with the air blowing mechanism. After the friction block cleans the impurities, the air blowing mechanism transports the water vapor to the groove through the exhaust hole through the pipeline. The friction block cooperates with the water in the water vapor to just remove the impurities on the upper and lower surfaces of the foamed silicone rubber, and can well remove stains, impurities and fingerprints, etc., with good cleaning effect. On the other hand, the water vapor flows along the groove, and can form a water flow to well guide the removed impurities into the collection box for better centralized treatment;

[0029] (4) A pair of counter-rotating rollers is also provided at the tail end of the cleaning device of the present invention. After the foamed silicone rubber passes through the gap between the counter-rotating rollers, it is conveyed in an upwardly convex arc shape, so that the foamed silicone rubber does not completely adhere to the platform of the frame. 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 winds the foamed silicone rubber, the blowing device generates an upward airflow to lift the foamed silicone rubber, facilitating the winding device to wind the foamed silicone rubber. When the foamed silicone rubber is conveyed in an arc shape, the wind force output by the blowing device can be trapped by the foamed silicone rubber, and the lower end surface of the foamed silicone rubber is prevented from being scratched;

[0030] (5) Two sets of cleaning devices, winding devices and visual inspection devices are provided in the present invention, and they are symmetrically arranged at both ends of the conveying device. Thus, after the foamed silicone rubber completes a detection and dust removal operation, once the detection result is unqualified, the foamed silicone rubber can be directly unrolled, cleaned and wound again from the other end of the conveying device, without transferring the foamed silicone rubber and without resetting the conveying device, making the operation process more convenient and efficient.

[0031] In summary, the present invention has the advantages of high-efficiency processing, improved processing efficiency, stability, safety, convenient operation, etc., and is particularly suitable for the technical field of automatic production of foamed silicone rubber.

[0053] Embodiment 1:

[0054] As Figures 1 to 17 shown, an automatic dust removal and re-inspection device for foamed silicone rubber coils includes a frame 1, and further includes a cleaning device 2, a conveying device 3, a winding device 4 and a vision detection device 5 installed on the frame 1;

[0055] The conveying device 3 reciprocates along the length direction of the upper platform 10 of the frame 1. The cleaning device 2 can efficiently and quickly clean the upper and lower end faces of the unwound foamed silicone rubber. The winding device 4 is responsible for neatly and tightly winding the foamed silicone rubber after cleaning and inspection for storage and transportation;

[0056] The cleaning device 2 is rotatably mounted on the frame 1. The cleaning device 2 includes a first eliminating roller 21, a second eliminating roller 22 and a blower mechanism 23. Both the first eliminating roller 21 and the second eliminating roller 22 are hollow. The first eliminating roller 21 is arranged directly above the second eliminating roller 22, and the two form an up-and-down relative layout, capable of simultaneously cleaning the upper and lower surfaces of the foamed silicone rubber synchronously. The first eliminating roller 21 and the second eliminating roller 22 are driven by a motor. The first eliminating roller 21 and the second eliminating roller 22 are connected by 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, which has the characteristics of large torque, wide speed regulation range and high precision. Moreover, the first eliminating roller 21 and the second eliminating roller 22 are arranged to rotate relatively. This relative rotation mode enables the foamed silicone rubber to be subjected to uniform frictional forces from the upper and lower directions when passing between the two rollers, and can more effectively remove surface impurities. At the same time, the speed difference of the relative rotation can also be adjusted according to the actual situation to further enhance the cleaning strength. The blower mechanism 23 is connected to the first eliminating roller 21 and the second eliminating roller 22. The blower mechanism 23 is composed of a wind box 231 and an air flow distribution pipeline 232. The wind box 231 generates a high-pressure air suction force. A water vapor atomization generating device is arranged inside the wind box 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 air flow distribution pipeline 232 and evenly transports the water vapor flow into the first eliminating roller 21 and the second eliminating 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;

[0057] Specifically, both the first eliminating roller 21 and the second eliminating roller 22 are coated with a magic eraser layer 211. The magic eraser layer 211 is a component that directly contacts the foamed silicone rubber during the cleaning process. The main component of its material is silica gel. Silica gel has elastic buffering characteristics. This elastic characteristic enables it to fit complex curved surfaces by moderate compression when contacting the surface of the foamed silicone rubber, ensuring sufficient frictional force to remove surface particle impurities, and at the same time avoiding material strain caused by excessive contact. The silica gel material itself belongs to non-polar macromolecules and has excellent compatibility with the silicone rubber substrate, which can effectively avoid the interfacial adhesion problem between the two. Silica gel has strong physical adsorption and friction decontamination capabilities. When cleaning the surface of the foamed silicone rubber, no cleaning agent needs to be added. Just dip it in water and gently wipe it to remove various stains, such as stains and water stains. Its microscopic structure can closely combine with impurities and separate the impurities from the silicone rubber surface through friction to ensure effective cleaning of the foamed silicone rubber;

[0058] Specifically, the outer surfaces of the first elimination roller 21 and the second elimination roller 22 are both coated with a cylindrical magic eraser layer 211. The surface of the magic eraser layer 211 is composed of several groups of symmetrically arranged friction blocks 2111. The friction blocks 2111 spiral around 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.

[0059] Moreover, a groove 2120 is formed between adjacent friction strips 2110. The groove 2120 is successively communicated with the internal hollow flow channel of the first elimination roller 21 or the second elimination roller 22 through the exhaust holes 2112 of the magic eraser layer 211, the first elimination roller 21 or the second elimination roller 22. The hollow flow channel is connected to an external air blowing mechanism 23, and the air blowing mechanism 23 conveys a water vapor flow to the hollow flow channel.

[0060] Furthermore, the V-shaped tip of the friction strip 2110 is in the same direction as the rotational angular velocity direction of the corresponding first elimination roller 21 or the second elimination roller 22;

[0061] A number of groups of exhaust holes 2112 are circumferentially arrayed on the magic eraser layer 211. 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 elimination roller 21 and the second elimination roller 22, the friction blocks 2111 on the first elimination roller 21 and the second elimination roller 22 clean the upper and lower surfaces of the foamed silicone rubber by friction. The air blowing mechanism 23 blows impurities to move to both sides along the arrangement direction of the friction blocks 2111 until they fall off;

[0062] The conveying device 3 drives the foamed silicone rubber to move along the length direction of the frame 1 to the lower part of the winding device 4, and the winding device 4 winds and arranges the foamed silicone rubber.

[0063] Further, the first elimination roller 21 and the second elimination roller 22 both further include an air delivery pipe 212. The air delivery pipe 212 is hollow and is arranged through the first elimination roller 21 and the second elimination roller 22. The air delivery pipe 212 is communicated with 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 bearing seats, and the magic eraser layer 211 is sleeved on the surfaces of the first elimination roller 21 and the second elimination roller 22 through a tooth structure;

[0064] The air delivery pipe 212 is provided with a blowing groove 2121. The orientation of the blowing groove 2121 forms an angle with the central axis of the axial direction of the air delivery pipe 212. The water vapor flow passes from the air box 231 through the air flow distribution pipe 231 to the blowing groove 2121. When the magic eraser layer 211 rotates, the water vapor flow is output from the exhaust hole 2112 corresponding to the blowing groove 211, and a cooperative cleaning mechanism is formed in cooperation with the V-shaped friction block 2111. The V-shaped friction block 2111 performs friction cleaning on 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 flow discharged from the exhaust hole 2112 can just blow the impurities along the direction guided by the friction block 2111, achieving a more thorough cleaning effect.

[0065] In addition, it should be noted that in order to improve the cleaning effect, fiber sponges can also be installed on the friction block 2111, that is, 1 / 4 or 1 / 3 of the number of the friction blocks 2111 are selected, grooves are dug on them, and the fiber sponges are embedded in the grooves. Then, with the effects of good water absorption and flexibility in cooperation with water vapor, it can effectively adsorb and remove impurities such as oil stains and fingerprints on the surface of the foamed silicone rubber. Moreover, the fine fiber structure of the fiber sponge can penetrate into the fine pores of the silicone rubber and clean out the impurities therein.

[0066] Furthermore, the cleaning device 2 further includes a pair of rollers 24. The pair of rollers 24 are rotatably installed on the frame 1 through bearing seats. By using the high-precision rolling bearings of the bearing seats, it is ensured that the pair of rollers 24 can rotate smoothly and smoothly on the frame 1, reducing the friction and mechanical loss during the rotation process, and ensuring the long-term stable operation of the equipment. The pair of rollers 24 includes 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 side by side up and down. The first row of rollers 241 is provided with a central depression, and the second row of rollers 242 is provided with a central protrusion. And the depression part of the first row of rollers 241 corresponds to the protrusion part of the second row of rollers 242. When the foamed silicone rubber completes the preliminary friction and blowing cleaning process between the first elimination roller 21 and the second elimination roller 22, at this time, there is a certain height difference between the output foamed silicone rubber and the pair of rollers 24. The blowing device 101 in the platform 10 blows out air upward through the ventilation hole 100. The air flow vertically impacts the foamed silicone rubber coming out from between the first elimination roller 21 and the second elimination roller 22. Due to the certain flexibility and elasticity of the foamed silicone rubber itself, under the continuous impact of the air flow, it begins to vibrate. The vibration helps to further remove the fine impurities remaining on the surface of the foamed silicone rubber. The rotation of the pair of rollers 24 and the interaction with the vibrating foamed silicone rubber can adjust the flatness of the surface of the foamed silicone rubber and further improve the product quality.

[0067] In addition, a number of ventilation holes 100 are provided on the upper and lower surfaces of the platform 10, and a number of groups of blowing devices 101 are arranged inside the platform 10. When the blowing devices 101 start working, 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 creation of this gap effectively isolates the direct contact between the two, thereby ensuring the surface integrity of the foamed silicone rubber.

[0068] It should be further explained that the cleaning device 2 also includes a collection box 25. The main function of the collection 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 processing and cleaning operations. The collection box 25 is fixedly installed on the frame 1. The collection 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 collection box 25 under the action of gravity, thereby achieving effective collection of impurities.

[0069] 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, thereby ensuring the stability of the position between the collecting box 25 and the first eliminating roller 21 and the second eliminating roller 22, avoiding horizontal deviation during operation, and ensuring the sealing performance between the first eliminating roller 21 and the second eliminating roller 22 and the collecting box 25, thereby preventing impurities from leaking from the gap and affecting the collection effect;

[0070] The collection box 25 is hingedly mounted with a flip cover 251. This design facilitates manual insertion of the foamed silicone rubber between the first elimination roller 21 and the second elimination roller 22, and also facilitates cleaning and maintenance of the collection box 25.

[0071] The collecting box 25 is provided with a discharge chute 252 on the side facing the pair of rollers 24. The design of the discharge chute 252 allows the foamed silicone rubber to directly enter the subsequent process after completing the cleaning process of the first and second eliminating rollers 21 and 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;

[0072] The bottom of the collection box 25 is in a hopper shape. This hopper structure is for facilitating the aggregation and discharge of impurities. During the cleaning process, after the impurities fall into the collection box 25, due to the action of gravity, they will gradually converge towards the center along the hopper bottom. A discharge channel 253 is provided at the bottom of the collection box 25, and the discharge channel 253 is connected to an external negative pressure suction dust collection device. The bottom of the collection box 25 is in a hopper shape. This hopper structure is for facilitating the aggregation and discharge of impurities. During the cleaning process, after the impurities fall into the collection box 25, due to the action of gravity, they will gradually converge towards the center along the hopper bottom. The hopper bottom can also reduce the dead corners of impurity accumulation, ensuring that all impurities can smoothly flow towards the discharge channel 253 at the bottom. The discharge channel 253 is connected to an external waste treatment system;

[0073] A baffle 254 is provided between the discharge chute 252 and the first elimination roller 21 and the second elimination roller 22. The setting of the baffle 254 separates the impurities in the collection box 25 from the cleaned foamed silicone rubber, preventing the cleaned foamed silicone rubber from being contaminated again and affecting the product quality. To a certain extent, this also facilitates the maintenance and cleaning work of the equipment. When it is necessary to clean the collection box 25, due to the isolation of the baffle 254, it is easier to clean the impurities at the bottom without worrying about affecting the transmission of the cleaned foamed silicone rubber. Secondly, the end of the baffle 254 is accurately docked with the inlet of the discharge chute 252. The baffle 254 can guide the foamed silicone rubber to accurately enter the discharge chute 252 after the foamed silicone rubber is cleaned by the first elimination roller 21 and the second elimination roller 22.

[0074] In addition, a guide plate 26 is provided between the first elimination roller 21, the second elimination roller 22 and the counter roller 24. One end of the guide plate 26 is connected to the collection box 25, and the guide plate 26 extends obliquely from the collection box 25 towards the counter roller 24. This inclined setting meets the transmission requirements of the foamed silicone rubber. When the foamed silicone rubber is cleaned by the first elimination roller 21 and the second elimination roller 22, it can move smoothly towards the counter roller 24 along the inclined angle of the guide plate 26 by virtue 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 situation of the foamed silicone rubber shifting or scattering during the transmission process, and ensuring the continuity and stability of the production process;

[0075] 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. Due to the elastic connection force of the elastic member 262, the connecting plate 261 is suspended on the frame.

[0076] Furthermore, the conveying device 3 includes jigs 31 and a lead screw slider group 32. There are two sets of both the jigs 31 and the lead screw slider group 32. The structural design of the jigs 31 fully considers the protection of the foamed silicone rubber. The surface in contact with the foamed silicone rubber uses a soft and wear-resistant material to avoid damaging the surface of the foamed silicone rubber during the clamping process. At the same time, the jigs 31 have sufficient clamping force to ensure that the foamed silicone rubber does not slip or fall off during the conveying process, guaranteeing the stability and safety of the conveying.

[0077] The jigs 31 are slidably mounted on both sides of the platform 10 through sliders 33. The sliders 33 provide precise guidance and stable support for the movement of the jigs 31, which can effectively reduce the frictional resistance of the jigs 31 during movement, making their movement smoother and more stable. At the same time, the rigidity and stability of the sliders 33 ensure that the jigs 31 do not shake or shift when carrying the foamed silicone rubber, further improving the accuracy and reliability of the conveying.

[0078] The jigs 31 are connected to the lead screw slider group 32. The lead screw slider group 32 drives the jigs 31 to move along the length direction of the platform 10 through its own rotation. One side of the lead screw slider group 32 is driven by a motor, and the two lead screw slider groups on both sides achieve synchronous rotation through a chain 34, ensuring that the jigs 31 on both sides can move synchronously, guaranteeing that the foamed silicone rubber remains symmetrical and stable during the conveying process, and avoiding deformation or damage of the foamed silicone rubber caused by inconsistent movement on both sides.

[0079] It should be noted that the jigs 31 include pneumatic jaws 311. Cooperating with the lead screw slider group 32 that reciprocates along the length direction of the platform 10 greatly optimizes the transportation link of the foamed silicone rubber in the entire production process. Through the reciprocating movement of the lead screw slider group 32, not only is the detour and repeated path of the jigs 31 during transportation reduced, avoiding unnecessary time waste, but also the space layout of the equipment can be fully utilized, improving the overall production efficiency and ensuring the smoothness and stability of the entire production process.

[0080] Further, the winding device 4 includes a vacuum suction cup assembly 41 and two groups of rotary pneumatic grippers 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. There is a lifting assembly between the vacuum suction cup assembly 41 and the frame 1. The vacuum suction cup assembly 41 moves vertically up and down relative to the platform 10 through the lifting assembly. Its main function is to use vacuum suction to preliminarily position and grasp 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 air extraction system, generating a pressure difference between the suction cup and the surface of the foamed silicone rubber, thereby firmly sucking the foamed silicone rubber. Such a 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;

[0081] The rotary pneumatic gripper 42 is installed on the frame 1. The rotary pneumatic gripper 42 can stably clamp and rotate the foamed silicone rubber, driving the foamed silicone rubber to wind around the winding center, ensuring that the foamed silicone rubber can be wound evenly and tightly on the component. The rotary pneumatic gripper 42 is composed of a gripper unit 421 and a rotary motor 422. The rotary motor 422 drives the gripper unit 421 to rotate;

[0082] A telescopic element 43 is arranged at the tail of the rotary pneumatic gripper 42. The telescopic element 43 drives the rotary pneumatic gripper 42 to approach the platform 10 side. The telescopic element 43 is preferably a cylinder, which can precisely control the telescopic stroke and speed of the rotary pneumatic gripper 42, thereby realizing effective clamping and winding operations for foamed silicone rubbers of different specifications and lengths;

[0083] During the winding process, first, the vacuum suction cup assembly 41 will descend to a suitable position, adsorb the foamed silicone rubber conveyed from the conveying device 3, lift it and position it at the starting position of winding. Then, the telescopic element 43 will drive the rotary pneumatic gripper 42 to approach the foamed silicone rubber. The rotary pneumatic gripper 42 performs a clamping operation on the foamed silicone rubber. Once the rotary pneumatic gripper 42 clamps the foamed silicone rubber, the vacuum suction cup assembly 41 can release the foamed silicone rubber. The rotary pneumatic gripper 42 starts to rotate, driving the foamed silicone rubber to wind. After the winding is completed, the position of the rotary pneumatic gripper 42 is adjusted through the telescopic element 43 to return to the initial position.

[0084] Embodiment 2:

[0085] As Figures 1 to 17 shown, the present invention also provides a usage method for an automatic dust removal and re-inspection device for a foamed silicone rubber coil applicable to that described in Embodiment 1, including the following steps:

[0086] Step 1: Preparation work. Place the foamed silicone rubber coil to be inspected on a trolley, transport it to the initial station using the trolley, start the hydraulic lift, lift the foamed silicone rubber coil to the outer side of the collection box. Manually operated by workers, guide the foamed silicone rubber through the gap between the first elimination roller 21 and the second elimination roller 22, and the gap between the opposing rollers 24 in sequence. After the threading is completed, connect one end of the foamed silicone rubber to the fixture 31 to achieve the preliminary positioning of the foamed silicone rubber;

[0087] Step 2: Cleaning of 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 elimination roller 21 and the second elimination roller 22. At this time, the relatively rotating first elimination roller 21 and the second elimination roller 22 use the friction blocks 2111 on the magic eraser layer 211 to frictionally clean the surface of the foamed silicone rubber. Meanwhile, 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;

[0088] Step 3: Transfer and arrangement of the foamed silicone rubber. When the foamed silicone rubber moves to the winding station driven by the fixture 31, the vacuum suction cup assembly installed on the frame generates sufficient suction to suck the foamed silicone rubber from the fixture 31. Subsequently, under the traction of the vacuum suction cup assembly, move the foamed silicone rubber to the winding station. At the winding station, the rotary pneumatic grippers 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 rotary pneumatic grippers 42 start to rotate. Meanwhile, the visual inspection device 5 located above and below the winding station synchronously inspects the foamed silicone rubber coil;

[0089] Step 4: When the foamed silicone rubber winding is completed, the winding device 4 stops working, and the rotary pneumatic grippers 42 release the foamed silicone rubber coil. If the inspection is qualified, the foamed silicone rubber coil is transferred to the trolley through the inclined platform for output;

[0090] Step 5: If the inspection is unqualified, after the foamed silicone rubber coil is transferred to the trolley through the inclined platform, repeat the above steps 1 to 4 to perform the cleaning and inspection work again.

[0091] Further, in step two, the rotation directions of the first cleaning roller 21 and the second cleaning roller 22 are opposite to the transportation direction of the conveying device 3, and the rotation directions of the first cleaning roller 21 and the second cleaning roller 22 are the same as the orientation of the friction block 2111, so that when the friction block 2111 rotates, it can contact the surface of the foamed silicone rubber more precisely and stably. When the foamed silicone rubber moves forward driven by the conveying device 3, the first cleaning roller 21 and the second cleaning roller 22 rotate reversely, cooperating with the friction block 2111 to strengthen the cleaning effect on the foamed silicone rubber and ensure that the surface cleanliness of the foamed silicone rubber meets the standard before entering the subsequent process.

[0092] Furthermore, in step two, 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 impurities removed are likely to stay at the edge position of the foamed silicone rubber due to insufficient space, and may even reattach to the foamed silicone rubber 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 will be formed on both sides of the foamed silicone rubber, and the impurities can easily fall from this buffer zone after being removed.

[0093] Furthermore, in step three, in terms of appearance, the visual inspection device 5 scans the surface of the material roll through an industrial camera imaging system to accurately identify defects such as scratches, bubbles, and impurities. In terms of performance parameter detection, it can accurately measure the thickness, width, and length parameters of the foamed silicone rubber material roll through the built-in laser sensor. The visual inspection device 5 will transmit the collected data information to the control system, and the control system will quickly analyze and process these data to determine whether the foamed silicone rubber material roll meets the quality requirements.

[0094] Specifically, the visual inspection device 5 located above is installed and connected to the vacuum suction cup assembly 41, while the visual inspection device 5 located below is embedded in the conveying device 3. The upper and lower groups of visual inspection devices 5 respectively detect the upper and lower end faces of the foamed silicone rubber.

[0095] In addition, it should be noted that in order to improve the detection and cleaning efficiency, two sets of cleaning devices 2 and winding devices 4 are provided in this application. The two sets of cleaning devices 2 and winding devices 4 are respectively arranged at both ends of the conveying device 3, and the fixture 31 of the conveying device 3 is also provided with two sets of pneumatic jaws 311, and the orientations of the jaws 311 on both sides are opposite. This enables the conveying device 3 to directly perform the next cleaning work through the cleaning device 2 on this side without returning after transporting the foamed silicone rubber to the winding device 4 on one side.

[0096] It should be further noted that after setting up the two sets of cleaning devices 2 and winding devices 4, in step four, when the rotary pneumatic gripper 42 clamps the foamed silicone rubber for winding, the guide plate 26 provided by the cleaning device 2 on the same side will abut against the foamed silicone rubber coil wound by the winding device 4, so that the foamed silicone rubber coil can always be in a good coiling state. And the elastic member 262 provided on the guide plate 26 will provide a compressive elastic force to the guide plate 26, so that the foamed silicone rubber coil can be in a tight coil state.

[0097] Specifically, an elastic member 262 is provided between the connecting plate 261 and the frame 1. 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 coil diameter will also continuously 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 coil diameter increases, the elastic member 262 will be compressed, causing the connecting plate 261 to move up appropriately. The connecting plate 261 maintains an appropriate pressure through the compression of the elastic member 262 to ensure that the pressure is always maintained at a level that can effectively press the foamed silicone rubber. This self-adaptive adjustment avoids deformation or damage of the foamed silicone rubber caused by excessive pressure, and at the same time prevents the pressing effect from not being achieved due to too small pressure.

[0098] Furthermore, in step five, the moving direction of the conveying device 3 is opposite to the moving direction of the conveying device 3 in step one. The design of reverse movement makes the entire foamed silicone rubber processing flow 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.

[0099] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
