Description

Technical Field

[0001] The present invention relates to a rubber coating device and a rubber coating method thereof, in particular to an arc extinguishing chamber rubber coating device and a rubber coating method thereof, and belongs to the technical field of arc extinguishing chamber production. Background Art

[0002] The current technology for coating vacuum interrupters with silicone rubber cushioning materials generally uses liquid silicone rubber mold injection molding. The specific process is as follows: first, the vacuum interrupter is placed in the mold cavity, then the mold is closed, and with the help of a liquid silicone rubber injection mechanism, liquid silicone rubber with a certain pressure is injected into the mold cavity. After the mold cavity is filled with liquid silicone rubber, the injection operation is stopped, and the mold is heated to solidify the liquid silicone rubber in the mold cavity, finally completing the silicone rubber coating of the vacuum interrupter surface. However, due to the large extrusion force generated during the injection process and the thin thickness of the metal end covers at the moving and static ends of the vacuum interrupter, the metal end covers at both ends of the vacuum interrupter are easily deformed due to this extrusion force. At the same time, the extrusion force causes the liquid silicone rubber to penetrate into the movable gap of the conductive rod of the moving contact, causing the movement of the contact to be obstructed, ultimately resulting in a low yield rate.

[0003] A known Chinese authorized invention patent (publication number: CN113035611B) discloses a device for coating the surface of a vacuum interrupter with silicone rubber. The device is provided with a fixing component that can fix the vacuum interrupter and is compatible with vacuum interrupters of various shapes and sizes. No traditional mold is required during operation, saving mold development time and mold development costs. No injection pressure is required during the process of coating the vacuum interrupter with silicone rubber using the device, thereby preventing the vacuum interrupter from being subjected to pressure and causing deformation of the moving end cover and the static end cover, and preventing liquid silicone rubber from seeping into the movable gap of the movable contact conductive rod and causing contact movement to be obstructed, thereby improving the qualified rate of product production. By providing an air drying component, the curing of the silicone rubber on the surface of the vacuum interrupter can be accelerated, thereby improving production efficiency.

[0004] Although this solves the problem of vacuum interrupter deformation, during the curing process of the silicone rubber, due to the fluidity of the liquid silicone rubber, the liquid silicone rubber at the top will drip downward under the action of gravity. This dripping silicone rubber accumulates on the outer wall of the vacuum interrupter. As the curing process progresses, it eventually forms bumps of varying sizes on the outer wall of the vacuum interrupter. These bumps not only damage the flatness and finish of the outer wall of the vacuum interrupter, but also may affect its insulation performance and appearance quality, thereby adversely affecting the overall quality of the product. To this end, a device and method for encapsulating the outer wall of the vacuum interrupter are proposed. Summary of the Invention

DETAILED DESCRIPTION

[0037] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] like Figures 1-8 As shown, an embodiment of the present invention provides an arc extinguishing chamber rubber coating device, including a base 41, a column 43 is installed on the base 41, a second linear module 35 is installed on one side of the column 43, and a rubber coating component 101 is installed on the mover of the second linear module 35. The rubber coating component 101 can be controlled to move upward or downward by the second linear module 35;

[0040] The rubber lagging assembly 101 includes a mounting frame 11, a vertical plate 17, a forming roller 24, a screw rod 27, a transmission motor 28 and a slider 29;

[0041] The vertical plate 17 is fixedly connected to the upper surface of the mounting frame 11. The rear surface of the vertical plate 17 is mounted with a first linear module 30. The mover of the first linear module 30 is fixedly connected to a lifting seat 26. The lifting seat 26 has a groove formed inside. The shape of the groove matches the shape of the slider 29. The slider 29 is slidably connected to the interior of the lifting seat 26.

[0042] The screw rod 27 is fixedly connected to the output shaft of the transmission motor 28. The lower surface of the slider 29 is fixedly connected to the forming frame 18. The slider 29 is threadedly connected to the outer wall of the screw rod 27. The screw rod 27 is rotatably connected to the inside of the lifting seat 26. The transmission motor 28 is installed on the rear surface of the lifting seat 26. The transmission motor 28 drives the screw rod 27 to rotate. The screw rod 27 drives the slider 29 through the thread on its surface. The slider 29 slides inside the lifting seat 26, thereby adjusting the front and rear position of the forming frame 18.

[0043] Two chute 21 are symmetrically provided inside the forming frame 18. The inner side walls of the two chute 21 are slidably connected to a sliding seat 23. The interior of the two sliding seats 23 is connected to a rotating rod 22 for common rotation. The outer side wall of the rotating rod 22 is fixedly connected to a forming roller 24 and a driven disk 25. The forming roller 24 is used to roll-form the silicone rubber on the outer wall of the arc extinguishing chamber to prevent the silicone rubber from gathering on the outer wall of the vacuum interrupter. During the curing process, the forming roller 24 always maintains contact with the vacuum interrupter, so that the silicone rubber does not form convex spots of varying sizes on the outer wall of the vacuum interrupter, thereby ensuring the flatness and smoothness of the outer wall of the vacuum interrupter.

[0044] The rear surface of the slider 29 is fixedly connected to the guide rod 20, and the outer side wall of the guide rod 20 is sleeved with a spring 19. The guide rod 20 is slidably connected to the inside of the forming frame 18. One end of the spring 19 abuts the rear surface of the sliding seat 23, and the other end of the spring 19 abuts the inner front wall of the slide groove 21. The sliding seat 23 is pushed to slide in the slide groove 21 by the spring 19. The sliding seat 23 drives the rotating rod 22, and the rotating rod 22 drives the forming roller 24 and the driven disk 25, so that the forming roller 24 can maintain contact with the silicone rubber layer outside the arc extinguishing chamber.

[0045] In one embodiment, the rubber lagging assembly 101 further includes a drive motor 12, a drive disc 13, a first joint 14, a second joint 15 and a locking cylinder 16;

[0046] The first joint 14 is fixedly connected to the output shaft of the drive motor 12, the second joint 15 is rotatably connected to the cylinder shaft of the locking cylinder 16, the drive disk 13 is fixedly connected to the outer wall of the first joint 14, the drive motor 12 is mounted on one side of the mounting frame 11, and the locking cylinder 16 is mounted on the other side of the mounting frame 11. The shape of the first joint 14 is adapted to the shape of the second joint 15. When the vacuum interrupter is installed and positioned, the vacuum interrupter is placed between the first joint 14 and the second joint 15. The locking cylinder 16 pushes the second joint 15. The second joint 15, in cooperation with the first joint 14, can clamp the vacuum interrupter.

[0047] When the vacuum interrupter is rotationally encapsulated with rubber, the first joint 14 is driven by the driving motor 12, and the first joint 14 drives the vacuum interrupter. The vacuum interrupter and the second joint 15 rotate along with the first joint 14, so that the outer wall of the vacuum interrupter can be evenly adhered to the silicone rubber.

[0048] In one embodiment, the forming frame 18 is located behind the first joint 14, and the outer wall of the driving disk 13 is in contact with the outer wall of the driven disk 25. When the driving motor 12 drives the first joint 14 to rotate, the first joint 14 drives the driving disk 13 to rotate. Since the driving disk 13 is in contact with the outer wall of the driven disk 25, the driving disk 13 drives the driven disk 25 to rotate, and the driven disk 25 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the forming roller 24 to rotate, so that the forming roller 24 can rotate synchronously with the vacuum interrupter, thereby forming the silicone rubber on the outer wall of the vacuum interrupter.

[0049] In one embodiment, the lagging assembly 101 further includes a drying rack 31 , a drying box 32 , an air nozzle 33 , and an air pipe 34 ;

[0050] The drying rack 31 is installed on the front surface of the mounting frame 11, the drying box 32 is fixedly connected to the lower surface of the drying rack 31, the air nozzle 33 is installed on the rear surface of the drying box 32, and the air pipe 34 is installed on one side of the drying box 32. A hot air pump (not shown in the figure) is installed inside the base 41. The air outlet of the hot air pump is connected to the air pipe 34 through a pipe, and then the hot air can flow into the drying box 32 through the air pipe 34, and then flow out from the air nozzle 33 and contact the silicone rubber on the outer wall of the vacuum interrupter, so that the silicone rubber on the outer wall of the vacuum interrupter is quickly cured.

[0051] In one embodiment, a silicone rubber holding pool 42 is installed on the upper surface of the base 41. The position of the silicone rubber holding pool 42 corresponds to the position of the mounting frame 11. The mounting frame 11 is fixedly connected to the mover of the second linear module 35. Liquid silicone rubber is contained in the silicone rubber holding pool 42. The mounting frame 11 is driven downward by the second linear module 35, and the mounting frame 11 drives the vacuum interrupter to move to the inside of the silicone rubber holding pool 42, thereby realizing the rubber encapsulation operation of the vacuum interrupter.

[0052] In one embodiment, a control panel 44 is mounted on the front surface of the column 43. The control panel 44 is used to control the working status of the drive motor 12, the locking cylinder 16, the transmission motor 28, the first linear module 30, the hot air pump, and the second linear module 35.

[0053] The interior of the column 43 is integrated with an intelligent control system, which can judge the current state of the silicone rubber according to the current drying temperature and drying time. When the silicone rubber is in a semi-dry state, the forming roller 24 forms the silicone rubber;

[0054] The specific steps include:

[0055] 1. Perception Layer: Data Collection and Transmission

[0056] During the entire implementation process, the perception layer serves as the "eyes" and "ears" of the system, and undertakes the important task of collecting key data such as drying temperature and drying time.

[0057] First, the deployment of temperature sensors is crucial. Multiple high-precision temperature sensors are carefully placed in various locations within the drying equipment, located around, on the top, and on the bottom near the silicone rubber placement area. These sensors utilize a combination of contact and non-contact technology. Contact temperature sensors directly contact the inner wall of the drying equipment or the surface of the silicone rubber carrier to obtain the closest approximation to the actual temperature of the silicone rubber. Non-contact temperature sensors use infrared temperature measurement to monitor the silicone rubber surface temperature in real time. Temperature sensors can collect temperature data at an extremely high frequency (multiple times per second) and convert this data into electrical or digital signals.

[0058] To record drying time, the system is equipped with a high-precision timer. From the moment the drying equipment starts drying the silicone rubber, the timer begins accurately recording the elapsed time. The timer communicates with the entire intelligent control system in real time, continuously transmitting time data to the system.

[0059] To ensure that collected data can be accurately and quickly transmitted to the intelligent control system, the system utilizes efficient data transmission technology. For wired transmission, industrial-grade Ethernet cables are used to connect devices such as temperature sensors and timers to the control system's core processor. This ensures stable and high-speed data transmission, avoiding data loss and delays. Wireless transmission modules, such as Bluetooth and Wi-Fi, are also included. These modules enable wireless data transmission in scenarios where wiring is inconvenient, ensuring flexible and comprehensive data collection. Data is also encrypted during transmission to prevent theft or tampering, ensuring data security and reliability.

[0060] 2. Data processing layer: information integration and analysis

[0061] After the temperature and duration data collected by the sensing layer are transmitted to the intelligent control system, they enter the data processing layer. At this layer, the system performs a series of complex processing operations on this raw data.

[0062] First and foremost, data preprocessing is essential. Sensors may be subject to interference from the external environment during data collection, resulting in errors or outliers. Therefore, the system applies filtering algorithms to the temperature data, removing noise and interference signals for smoother and more accurate results. For abnormal temperature data, the system assesses and corrects them based on historical data and a reasonable temperature range. Furthermore, the system verifies the validity of drying time data to ensure accurate time recording and eliminate erroneous duration data caused by timer failure or other reasons.

[0063] After data preprocessing, the system conducts an in-depth analysis of the temperature data. First, it calculates temperature trends and, by comparing temperature data at different time points, analyzes whether the temperature is rising, falling, or remaining stable, as well as the rate of temperature change. For example, the system calculates the degree of temperature increase or decrease per minute and plots a temperature-over-time curve to visually demonstrate temperature changes. Second, it analyzes temperature distribution differences at different locations. By comparing the data collected by various temperature sensors, it understands the uniformity of the temperature field within the drying equipment and determines whether there is local overheating or overcooling.

[0064] The system combines drying time data with temperature data for comprehensive analysis. A relationship model between drying time and temperature is established based on the characteristics and process requirements of different types of silicone rubber. For example, for a specific silicone rubber, drying time is inversely proportional to temperature within a certain temperature range: higher temperatures require shorter drying times. However, there is also an upper temperature limit, exceeding which quality issues may occur. By studying and analyzing extensive historical data, the system continuously optimizes this relationship model to more accurately reflect the actual conditions during the silicone rubber drying process.

[0065] 3. Decision-making layer: state judgment and instruction generation

[0066] After the data processing layer integrates and analyzes the temperature and duration data, the intelligent control system enters the decision-making layer, which is the core "brain" of the entire system. It is responsible for judging the current state of the silicone rubber and deciding when to drive the forming roller 24 to perform the forming operation.

[0067] The system pre-stores a large amount of characteristic data on silicone rubber in different states. This data is derived from extensive experiments and actual production experience. Silicone rubber states are mainly divided into wet, semi-dry, and completely dry states, each with a unique temperature-time characteristic curve.

[0068] To determine the silicone rubber's state, the system compares and analyzes current temperature-time data with pre-stored characteristic data. When the silicone rubber is wet, the temperature rises relatively slowly and remains low for a period of time. This is because the silicone rubber contains a large amount of solvent, and the evaporation of the solvent requires heat, resulting in a subtle temperature rise. As drying progresses, the solvent gradually decreases, and the temperature rise accelerates. When the system detects that the temperature rise rate reaches a certain threshold and remains stable within a certain range, it combines the drying time data to determine that the silicone rubber has entered a semi-dry state. In this semi-dry state, a thin solid film begins to form on the silicone rubber's surface, but a certain amount of solvent is still present. The temperature-time curve at this time has distinct characteristics. By identifying and analyzing these characteristics, the system accurately determines whether the silicone rubber is in a semi-dry state. When the silicone rubber reaches a completely dry state, the temperature stabilizes, no longer showing a significant upward trend, and this trend persists for a period of time.

[0069] Once the system determines that the silicone rubber is in a semi-dry state, the decision-making layer immediately generates appropriate instructions. These instructions include a signal to activate the forming roller 24 and set operating parameters for the forming roller 24, such as speed and pressure. These parameters are based on in-depth research into silicone rubber properties and molding processes. Different types of silicone rubber require different speeds and pressures when molding in a semi-dry state. The system automatically adjusts the operating parameters of the forming roller based on the specific type and current state of the silicone rubber to ensure optimal molding results.

[0070] 4. Execution layer: instruction transmission and operation implementation

[0071] The instructions generated by the decision-making layer are transmitted to the execution layer through the control system's communication module. The execution layer mainly consists of equipment such as the drive device and the forming roller 24, and is responsible for receiving instructions and executing the corresponding operations.

[0072] The communication module uses reliable communication protocols such as Modbus and Profibus to accurately transmit instructions generated by the decision-making layer to the drive unit. Upon receiving the instructions, the drive unit first parses them and extracts information about the operating parameters of the forming roller 24. The drive unit then controls the operation of the motor based on these parameters. The motor is connected to the forming roller 24 via a transmission mechanism. Changes in the motor's speed and torque are transmitted to the forming roller 24 through the transmission mechanism, ensuring that the forming roller 24 operates at the speed and pressure specified by the instructions.

[0073] During the operation of the forming roller 24, the execution layer is equipped with a feedback mechanism to ensure the accuracy and stability of the forming process. Position sensors and pressure sensors are installed at key locations on the forming roller 24 to monitor its position and the pressure applied to the silicone rubber in real time. The data collected by these sensors is fed back to the intelligent control system, which compares the feedback data with the parameters specified in the command. If any deviation is detected between the actual parameters and the command parameters, the system will promptly adjust the output of the drive device and correct the operating status of the forming roller 24 to ensure that the forming process proceeds according to the predetermined parameters.

[0074] The execution layer also features fault detection and emergency response capabilities. If an abnormality such as a motor failure or transmission mechanism jam occurs during the forming process, the execution layer's fault detection device immediately detects the abnormality and transmits the fault information to the intelligent control system. Upon receiving the fault information, the control system quickly responds by stopping the forming rollers 24 and sounding an alarm, notifying the operator to troubleshoot and address the problem, thereby preventing further damage to the equipment and product.

[0075] 5. System Optimization and Maintenance

[0076] The entire intelligent control system is not static. During actual operation, it needs to be continuously optimized and maintained to ensure its stable and reliable performance.

[0077] The system regularly reviews and analyzes collected data. By comparing actual production data with expected data, it identifies any issues with the system's assessment of the silicone rubber's condition and control of the molding process. For example, if poor silicone rubber molding results are observed repeatedly, the system will analyze whether the cause is inaccurate temperature judgment, improper molding parameter settings, or a malfunction in the execution layer equipment. Based on the analysis results, the system's algorithms, models, and parameters are optimized and adjusted to continuously improve the system's accuracy and reliability.

[0078] At the same time, perform regular maintenance and upkeep on the system's hardware. Check the operating status of devices like temperature sensors, timers, and drivers, and promptly replace aging or damaged components to ensure proper operation. Inspect and maintain data transmission lines to prevent issues like aging and short circuits from impacting data transmission stability.

[0079] Furthermore, with the continuous advancement of silicone rubber materials and improvements in production processes, intelligent control systems also require corresponding upgrades and expansions. For example, when new silicone rubber materials emerge, the system needs to be able to learn and identify the drying process and molding parameters of these new materials. By updating the system's database and algorithms, it can adapt to the production needs of these new materials.

[0080] Through the collaborative work of the above-mentioned perception layer, data processing layer, decision-making layer, execution layer, and system optimization and maintenance, the intelligent control system inside the column 43 can accurately judge the current state of the silicone rubber based on the current drying temperature and drying time, and drive the forming roller 24 to form the silicone rubber when the silicone rubber is in a semi-dry state, thereby ensuring product quality and production efficiency.

[0081] A method for encapsulating an arc extinguishing chamber, comprising the following steps:

[0082] Positioning and installation of the arc extinguishing chamber: Place the arc extinguishing chamber between the first joint and the second joint, and push the second joint with the locking cylinder. With the cooperation of the two joints, the position of the arc extinguishing chamber is fixed;

[0083] Rotary rubber encapsulation: The second linear module drives the mounting frame downward, the arc extinguishing chamber moves to the inside of the silicone rubber holding pool, the driving motor drives the first joint to rotate, the first joint drives the arc extinguishing chamber, and the outer wall of the arc extinguishing chamber adheres to the silicone rubber;

[0084] Rotary drying: The second linear module drives the arc extinguishing chamber to reset, and air is blown out of the drying box to dry the silicone rubber on the outer wall of the arc extinguishing chamber;

[0085] Roller forming: During the drying process, the first linear module drives the forming roller to move downward, and the transmission motor drives the forming roller to move forward. The driven disc contacts the driving disc, and the forming roller contacts the silicone rubber and rotates with the arc extinguishing chamber. During the rotation, the forming roller flattens the silicone rubber layer.

[0086] When the present invention is working: first install the vacuum interrupter, place the vacuum interrupter between the first joint 14 and the second joint 15, one end of the vacuum interrupter contacts the first joint 14, and then push the second joint 15 through the locking cylinder 16. The second joint 15 can clamp the vacuum interrupter with the cooperation of the first joint 14. The position of the vacuum interrupter is fixed, and the mounting frame 11 is driven downward by the second linear module 35. The mounting frame 11 drives the vacuum interrupter to move to the inside of the silicone rubber holding pool 42. At this time, the vacuum interrupter can be encapsulated with rubber. Operation, the first joint 14 is driven by the driving motor 12, and the first joint 14 drives the vacuum interrupter. The vacuum interrupter and the second joint 15 both rotate along with the first joint 14, so that the outer wall of the vacuum interrupter can be evenly adhered to the silicone rubber. The vacuum interrupter is driven to reset upward by the second linear module 35. At this time, the silicone rubber on the outer wall of the vacuum interrupter is dried. The hot air can flow into the drying box 32 through the air pipe 34, and then flow out from the air nozzle 33 to contact the silicone rubber on the outer wall of the vacuum interrupter, so that the silicone rubber on the outer wall of the vacuum interrupter is quickly cured. During the curing process, the vacuum interrupter keeps rotating, and at the same time, the first linear module 30 drives the lifting seat 26 to move downward, the lifting seat 26 drives the forming frame 18, the forming frame 18 drives the forming roller 24 to move downward, and then the transmission motor 28 drives the screw rod 27 to rotate, the screw rod 27 drives the slider 29 through the thread on its surface, the slider 29 slides forward inside the lifting seat 26, the slider 29 drives the forming frame 18, the forming frame 18 drives the forming roller 24 and the driven disk 25, the driven disk 25 is in contact with the outer wall of the driving disk 13, and the driving disk 13 drives the driven disk 25. The moving disc 25 rotates, and the driven disc 25 drives the rotating rod 22 to rotate. The rotating rod 22 drives the forming roller 24 to rotate, thereby making the forming roller 24 rotate synchronously with the vacuum interrupter. During the rotation process, the forming roller 24 flattens the silicone rubber layer, thereby forming the silicone rubber on the outer wall of the vacuum interrupter. During the forming process, the sliding seat 23 is pushed to slide in the slide groove 21 by the spring 19. The sliding seat 23 drives the rotating rod 22, and the rotating rod 22 drives the forming roller 24 and the driven disc 25, thereby making the driven disc 25 keep in contact with the driving disc 13 to ensure the forming effect.

[0087] Compared with the prior art, the present invention uses a forming roller 24 to roll-form the silicone rubber on the outer wall of the arc extinguishing chamber to avoid the silicone rubber from gathering on the outer wall of the vacuum arc extinguishing chamber. During the curing process, the forming roller 24 always maintains contact with the vacuum arc extinguishing chamber, and the silicone rubber will not form bumps of different sizes on the outer wall of the vacuum arc extinguishing chamber, thereby ensuring the flatness and smoothness of the outer wall of the vacuum arc extinguishing chamber.

[0088] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications and substitutions within the technical scope disclosed in the present invention, and such modifications and substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
