Description

Technical Field

[0001] This invention relates to the field of smart wearable device manufacturing technology, and in particular to a smart waterproof ring production apparatus, system and method. Background Technology

[0002] With the rapid development of wearable electronics technology, smart rings, with their advantages of small size, comfortable wear, and high functional integration, are gradually becoming a new growth point in the consumer electronics market, and are widely used in health monitoring, sports tracking, mobile payment, identity authentication, and many other fields. Waterproof performance is a core technical indicator of smart rings, directly determining the product's usage scenarios and lifespan. In particular, the waterproof requirements of IP68 and above necessitate completely sealing and encapsulating the internally integrated sensors, batteries, circuit boards, and other electronic components with potting compound to prevent the intrusion of external moisture and dust. For example, Chinese patent CN121798816A discloses a smart ring potting mold, including a ring silicone mold, a smart ring, a acetal fixture shell, a base, an acetal pressure block, a soft silicone pad, a pressure plate, and screws; wherein, the ring silicone mold forms a cavity for accommodating the smart ring, and the ring silicone mold has a potting hole; the acetal fixture shell is used to accommodate and fix other components; the base is disposed inside the acetal fixture shell to support the ring silicone mold; the acetal pressure block and the soft silicone pad are sequentially disposed above the ring silicone mold; the pressure plate and screws are used to press and fix the acetal pressure block and the soft silicone pad onto the acetal fixture shell.

[0003] However, in the above technical solution, after the potting operation is completed, the mold carrying the ring needs to be transferred from the potting station to the vacuum degassing equipment. During this transfer process, the two-component potting compound has already begun to undergo cross-linking reaction and enter the initial gel stage. The fluidity of the sealant will decrease sharply. At this time, applying a vacuum environment for degassing can only remove the larger air bubbles on the surface of the sealant. A large number of tiny air bubbles dispersed inside the sealant and at the sealing interface between the sealant and the ring are already wrapped and fixed by the gradually solidified sealant and cannot rise and be discharged by buoyancy. These locked tiny air bubbles will form natural defects inside the sealant, becoming a hidden danger for subsequent waterproofing failure. Therefore, the time difference between potting and degassing will cause the air bubbles to be permanently locked by the solidified sealant. Furthermore, for brand-new silicone molds, the fit between the mold and the ring is highly precise with extremely small gaps. Gas cannot easily escape through such narrow channels, easily leading to severe air entrapment within the injection space. As the mold is used repeatedly, the silicone material undergoes natural wear and aging, gradually increasing the gap. While this reduces venting resistance, it also causes excessive sealant overflow. Excessive gaps also result in a loose seal, increasing the risk of moisture intrusion. A stable balance between venting effectiveness and sealing performance cannot be found. Therefore, relying solely on the gap between the silicone mold and the ring for natural venting is extremely inefficient and unstable. In conclusion, completely separating the venting process from the injection process and using a post-treatment of overall vacuum degassing after injection cannot completely eliminate air bubbles generated during injection, and residual bubbles easily reduce waterproof reliability.

[0004] In summary, post-degassing causes the colloid to solidify and lock in the interface and internal micro-bubbles. Relying solely on the gaps in the mold for air release results in either trapped air due to insufficient gaps or leakage due to excessive gaps. It is difficult to achieve both effective air release and sealing performance. Residual air bubbles form seepage channels, significantly reducing the reliability of the ring's waterproofness. Therefore, there is an urgent need for an intelligent waterproof ring production device, system, and method that can balance effective air release and sealing performance. Summary of the Invention

[0005] This invention provides an intelligent waterproof ring production device, system, and method that can balance venting effect and sealing performance, thereby improving waterproof reliability.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: A method for producing a smart waterproof ring includes the following steps: S1 Ring housing and coaxial alignment: The elastic silicone mold body is detachably embedded in the annular mounting groove in the center of the base plate. The ring to be sealed is coaxially arranged on the outside of the boss of the lower mold base and inside the elastic silicone mold body. The outer wall of the boss and the inner ring of the ring to be sealed are engaged to achieve circumferential positioning, so that the outer wall of the boss, the outer wall of the ring to be sealed and the inner wall of the elastic silicone mold body form an annular cavity for injecting sealant. S2 Mold Closure Positioning and Pressure Holding Sealing: The guide pins of the lower mold base are sequentially inserted into the second positioning hole through the base plate and the first positioning hole of the upper mold base to achieve coaxial mold closing of the upper mold base, base plate, and lower mold base. After mold closing, a uniform axial pressure is applied to the upper and lower mold bases to seal the annular cavity and form a sealed injection space. Among them, the circumferential micropores of the elastic silicone mold body are connected to the through groove of the lower mold base to form an exhaust channel connecting the annular cavity, and the injection channel of the upper mold base is connected to the annular cavity. S3 Pre-vacuuming to establish a negative pressure potting environment: The sealed potting space is evacuated through the exhaust channel composed of the through groove of the lower mold base and the micropores of the elastic silicone mold body to establish a preset negative pressure potting environment and simultaneously discharge the residual air inside the annular cavity. S4 Uniform speed injection and synchronous venting: Sealant is injected into the annular cavity at a uniform speed through the injection channel set through the upper mold base; during the entire injection process, residual gas and sealant volatilization gas generated inside the annular cavity are continuously discharged to the outside through the venting channel formed by the micropores of the elastic silicone mold and the through groove of the lower mold base, so as to always maintain a bubble-free injection environment inside the annular cavity. S5 Pressure Detection and Sealant Filling Status Recognition: Real-time acquisition of pressure data inside the sealing and filling space; recognition of the filling progress of the sealant inside the annular cavity based on the dynamic changes of the pressure data; output of a filling completion trigger signal when the sealant completely fills the annular cavity. S6 Stop dispensing and pressure holding for curing: After receiving the filling completion trigger signal, cut off the sealant delivery to the upper mold base dispensing channel; continue to maintain the axial pressure holding state of the upper and lower mold bases until the sealant in the annular cavity has completed its initial curing.

[0007] The basic principle and beneficial effects of this solution are as follows: This solution adopts a circumferential limiting structure that precisely fits the integrated boss of the lower mold base with the inner ring of the ring to be sealed. This structure can provide all-round radial positioning and constraint for the ring to be sealed, avoiding problems such as ring offset, shaking, and eccentricity during the glue-pouring process. It precisely aligns and encloses a ring cavity with regular dimensions, closed boundaries, and a standard shape. This ring cavity has high molding accuracy and strong spatial independence, unlike open or intermittent molding structures. On this basis, combined with the overall mold closing and axial uniform pressure sealing, the upper mold base, base plate, lower mold base, and elastic silicone mold body are assembled and fitted together. The tight, compacted fit eliminates redundant gaps, seams, and loose spaces in the assembly, creating a completely sealed annular cavity structure. This closed, gapless molding environment prevents process defects such as liquid sealant overflowing under pressure, edge run-out, and localized leakage from the source. It effectively solves the problem of mold gap matching, ensuring stable and non-leaking adhesive filling during the dispensing process. The final annular adhesive layer has a uniform thickness, neat edges, and a dense fit, ensuring a tight fit between the sealant ring, the sealant, the upper mold base, and the lower mold base, with no gaps or voids, thus improving the stability and integrity of the overall sealing structure.

[0008] Meanwhile, this solution adopts an independent dual-channel layout with completely separate glue injection and venting processes, ensuring that the glue injection and venting processes do not interfere with each other and each performs its own function. This structural design removes the constraints imposed by sealing performance on venting effectiveness. Specifically, the upper mold base has a dedicated through-type glue injection channel, enabling targeted, directional, and uniform delivery of sealant, ensuring a stable sealant filling path and uniform, controllable feeding, and preventing turbulent flow of the sealant that could trap gas. Venting utilizes a directional venting path formed by the circumferentially densely distributed micropores of the elastic silicone mold body and the dedicated through-slots of the lower mold base. The micropores are small in diameter, evenly distributed, and smoothly conductive, precisely connecting to various areas at the top of the annular cavity, achieving venting without dead angles and completing efficient venting without relying on mold assembly gaps. In the process mating layer… First, a dedicated exhaust channel is used to pre-vacuum the sealed annular cavity, replacing and expelling any residual room-temperature air inside to create a stable negative pressure vacuum environment. This reduces the initial gas residue. Subsequent encapsulation processes employ a low-speed, uniform encapsulation mode, allowing the sealant to smoothly fill the cavity from bottom to top without impact or turbulence. Residual air squeezed out by the sealant and gases volatilized from heated sealant are quickly, orderly, and continuously expelled through micropores and channels, preventing gas retention, localized air trapping, and air encapsulation within the sealant. This dedicated dual-channel structure, combined with a continuous negative pressure venting process, achieves a dual technical advantage: "sealed cavity for sealing, dedicated pathway for venting," balancing the process contradictions of sealing and venting. Finally, the continuous axial pressure curing process after encapsulation continuously tightens the sealing interface, preventing gaps and micropores caused by sealant shrinkage during curing, thus enhancing overall sealing performance.

[0009] In summary, while ensuring high sealing performance through closed-loop pressure, the system achieves excellent venting effect by relying on a dedicated directional venting channel and a negative pressure full-process venting process, perfectly balancing the performance of both aspects and effectively improving the quality of smart ring potting and molding as well as its long-term waterproof reliability.

[0010] Furthermore, in S5, a pressure detection module is used to collect pressure data inside the annular cavity in real time and transmit the pressure data to the central control module. The central control module calculates the pressure change rate based on the pressure data. When the pressure change rate exceeds the preset pressure change threshold, it determines that the annular cavity has been completely filled with sealant and generates a filling completion trigger signal.

[0011] The beneficial effects are as follows: by replacing static pressure threshold judgment with real-time dynamic monitoring of the pressure change rate, the instantaneous state of the sealant filling the annular cavity can be accurately identified, effectively adapting to the pressure fluctuation conditions of negative pressure potting, preventing premature shutdown due to incomplete filling and overfilling, improving the identification accuracy and automation of the potting termination point, ensuring that each ring is fully and consistently potted, and steadily improving the waterproof sealing qualification rate of the product.

[0012] Furthermore, in S6, after the central control module generates a filling completion trigger signal, it outputs a dispensing stop command to the quantitative dispensing module. After receiving the dispensing stop command, the quantitative dispensing module terminates the quantitative injection of sealant. Simultaneously, the central control module outputs a pressure holding and sealing command to the pressure holding and sealing module. The pressure holding and sealing module includes a pneumatic control unit and a cylinder. The pneumatic control unit drives the cylinder to remain in the extended state and continuously applies uniform axial pressure to the upper mold base and the lower mold base until the sealant is initially cured. After the sealant is initially cured, the pneumatic control unit drives the cylinder to retract and release pressure.

[0013] The beneficial effects are as follows: by adopting the linkage control of glue pouring and pressure holding, the supply of sealant can be cut off instantly, eliminating over-pouring and overflow; by continuously stabilizing and holding pressure through a pneumatic cylinder, the stress of colloid curing shrinkage is offset, avoiding the formation of micro gaps and air holes in the colloid layer. The manual delayed pressure control mode is eliminated, the control sequence is precise and the pressure is constant, effectively improving the density of colloid curing and the consistency of molding, and greatly improving the sealing stability and production yield of smart waterproof rings.

[0014] Furthermore, in S6, the pneumatic control unit drives the cylinder to perform low-amplitude reciprocating micro-motion within a preset air pressure range and a preset stroke range; during the reciprocating micro-motion of the cylinder, the pressure inside the annular cavity fluctuates regularly, and the dynamic pressure fluctuation breaks up the residual air bubbles inside the colloid. At the same time, relying on the slight mechanical vibration generated by the cylinder micro-motion, the residual air bubbles inside the colloid move and gather towards the surface of the sealant; after all the residual air bubbles have migrated to the surface of the sealant, the pressure is maintained until the sealant has completed its initial curing.

[0015] The beneficial effects are as follows: Traditional pressure-holding processes mostly adopt a static constant-pressure curing mode, where the pressure inside the annular cavity remains constant without fluctuation. Micron-sized air bubbles remaining inside the adhesive after potting are difficult to escape and dissipate on their own, easily becoming hidden within the adhesive layer and forming tiny pores. This damages the density of the sealant layer, leading to water leakage and failure with long-term use. This solution, through a dynamic pressure-holding structure with small reciprocating movements of a cylinder, breaks through the limitations of static pressure-holding processes. It precisely controls the air pressure range and movement stroke, creating regular micro-pressure fluctuations inside the annular cavity without damaging the adhesive layer's structure or causing deformation. This effectively squeezes and breaks up the hidden microbubbles inside the adhesive, eliminating bubble defects from within. Simultaneously, the uniform, slight vibration generated by the cylinder's micro-movement drives any remaining unbroken air bubbles inside the adhesive to gradually migrate and gather towards the adhesive layer surface, achieving concentrated removal of residual air bubbles. This thoroughly eliminates micro-hidden air bubbles that conventional negative pressure venting cannot remove, comprehensively improving the density, uniformity, and structural stability of the sealant layer. This significantly improves the waterproof rating and long-term reliability of the smart waterproof ring, reducing the product defect rate.

[0016] Furthermore, in S6, the pneumatic control unit pre-stores a preset air pressure range and a preset stroke range adapted to the curing characteristics of the sealant. The pneumatic control unit drives the cylinder according to the preset air pressure range and the preset stroke range, so that the cylinder performs low-amplitude, high-frequency reciprocating micro-motion within the preset air pressure range and the preset stroke range. The preset air pressure range is a pressure fluctuation range that does not disturb the formation of the sealant layer, and the preset stroke range is a micro-displacement range that does not disturb the formation of the sealant layer.

[0017] The beneficial effects are as follows: If the cylinder's micro-motion air pressure and stroke do not have a standardized range, problems such as excessive air pressure and excessive stroke are very likely to occur, leading to molding defects such as mold closing misalignment, adhesive layer extrusion deformation, and ring misalignment and eccentricity. If the micro-motion amplitude is too small, it is difficult to form effective pressure fluctuations and vibration effects, resulting in a significant reduction in bubble removal and extremely poor process stability. This solution pre-matches the curing characteristics of the sealant, locks in a dedicated air pressure range and stroke range, and achieves precise and controllable output of low-amplitude reciprocating micro-motion of the cylinder. This avoids molding defects caused by large-amplitude movements and ensures effective bubble breaking and defoaming process conditions. Such controllable small-amplitude air pressure fluctuations can continuously knead the internal structure of the adhesive, breaking up hidden micron-sized residual bubbles. Precise micro-stroke vibration can stably guide bubbles to migrate to the surface of the adhesive layer without damaging the overall molding structure and sealing interface of the adhesive layer. Deep defoaming optimization is completed within the pressure holding process, greatly improving the density and uniformity of the sealant layer, effectively unifying the molding quality of batch products, and significantly improving the waterproof performance and production qualification rate of smart waterproof rings.

[0018] Furthermore, in S2, after the upper mold base, base plate, and lower mold base are coaxially closed, the pneumatic control unit and cylinder of the pressure holding and sealing module apply axial pressure evenly to the end faces of the upper mold base and lower mold base. The axial pressure is evenly distributed along the central axis of the upper mold base and lower mold base to ensure that the contact surfaces of the upper mold base, lower mold base, base plate and elastic silicone mold are evenly compacted, so that the annular cavity is subjected to balanced force and the sealed shape is stable.

[0019] The beneficial effects are as follows: relying on the pneumatic control unit and cylinder to complete axial pressure holding, the pressure application is flexible and uniform with strong pressure stability, which can ensure that each assembly interface is subjected to consistent force and fits tightly, eliminating local gaps and deformation defects, ensuring the regularity and stability of the annular cavity structure, and perfectly adapting to the negative pressure exhaust and cylinder micro-movement bubble breaking process; a unified power source avoids the problem of uneven exhaust and bubble residue caused by pressure deviation, greatly improving the consistency of potting and molding, effectively ensuring that the adhesive layer is dense and uniform, and improving the waterproof performance and mass production stability of the product.

[0020] Furthermore, in S6, the preset air pressure range adapted to the curing characteristics of the sealant is obtained through experimental calibration: sealant samples of the same batch are selected, and the rheological parameters and curing stress parameters of the sealant are collected at each stage of heating and melting, colloid filling, preliminary curing, and shaping and hardening. Combined with the size parameters of the annular cavity structure, multiple iterative tests are conducted on the forming state and defoaming effect of the adhesive layer under different air pressure loads. The optimal air pressure range that can ensure no deformation and no overflow of the adhesive layer, and can also achieve efficient breaking and migration of residual bubbles is selected. This optimal air pressure range is solidified as the preset air pressure range adapted to the curing characteristics of the sealant and pre-stored in the pneumatic control unit for later use.

[0021] The beneficial effects are as follows: Traditional equipment relies heavily on manual experience to preset air pressure parameters, without adapting and calibrating them to the curing rheological characteristics of the sealant. This results in poor parameter matching and easily leads to problems such as deformation due to excessive air pressure and defoaming failure due to excessive air pressure. It also cannot adapt to the curing differences of different sealant formulations. This solution, through multi-stage parameter acquisition and iterative calibration under multiple working conditions, specifically matches the curing characteristics of the sealant throughout the entire process. The preset air pressure range obtained has extremely strong process adaptability. This can accurately balance the defoaming function of dynamic pressure holding and the molding protection function. It ensures that the pressure fluctuations generated by the cylinder micro-movement effectively break up the trace bubbles in the sealant and drive the bubbles to migrate and precipitate. It can also completely avoid defects such as sealant layer collapse, ring misalignment, and overflow defects caused by abnormal pressure. At the same time, the standardized pre-stored recall mode can realize the uniform replication of the mass production process, eliminate the individual errors of manual parameter adjustment, and significantly improve the stability, consistency, and yield of intelligent waterproof ring potting molding.

[0022] Furthermore, in S6, the preset stroke range adapted to the curing characteristics of the sealant is obtained through experimental calibration: the same batch of sealant and the upper and lower mold bases are selected, and the cavity depth and adhesive layer thickness of the annular cavity are combined. Multiple sets of tests are conducted on the adhesive layer forming state, bubble migration efficiency and mold fitting accuracy under different cylinder micro-motion strokes. The problems of adhesive layer extrusion deformation, ring eccentric displacement and interface loosening caused by excessive stroke, as well as insufficient vibration energy and incomplete defoaming caused by insufficient stroke, are investigated one by one. The optimal micro-motion stroke range that balances flawless forming and efficient defoaming and migration is selected. This optimal micro-motion stroke range is solidified as the preset stroke range adapted to the curing characteristics of the sealant and pre-stored in the pneumatic control unit for later use.

[0023] The beneficial effects are as follows: Traditional micro-motion stroke settings often rely on fixed empirical parameters, without adapting and adjusting them to the micro-adhesive layer structure of the ring's annular cavity and the curing characteristics of the sealant. This results in a low degree of matching between stroke parameters and actual production conditions. Inappropriate stroke parameters can easily lead to two types of defects: excessive stroke generates excessive mechanical vibration and displacement, causing ring coaxiality misalignment, adhesive layer compression and collapse, and misalignment of the sealing interface; insufficient stroke results in insufficient mechanical vibration amplitude, failing to create an effective bubble disturbance effect, making it difficult for hidden microbubbles to migrate and precipitate, thus rendering the defoaming process ineffective. This solution, through multi-gradient stroke iterative testing and calibration, accurately locks the optimal micro-motion range adapted to the micro-adhesive layer structure. It can output stable vibration energy to drive microbubble migration and breakage, thoroughly eliminating hidden bubble defects in the adhesive, while ensuring precise mold alignment and regular adhesive layer formation throughout the process. Furthermore, standardized pre-stored stroke parameters enable uniform replication of the mass production process, avoiding errors from manual parameter adjustment and significantly improving product molding consistency and waterproof sealing reliability.

Detailed Implementation

[0025] The following detailed description illustrates the specific implementation method: The diagram in the instruction manual is labeled as follows: Upper mold base 1, Lower mold base 2, Base plate 3, Elastic silicone mold body 4.

[0026] Example 1 This embodiment provides an intelligent waterproof ring production device, as shown in the attached figure. Figure 1-4 As shown, the system includes a plate-shaped upper mold base 1, a plate-shaped lower mold base 2, a plate-shaped base plate 3, and a cylindrical elastic silicone mold body 4. The outer contours of the upper mold base 1, lower mold base 2, and base plate 3 are matched, and the base plate 3 is horizontally sandwiched between the upper mold base 1 and lower mold base 2. A cylindrical through-hole for injection is vertically opened on the upper mold base 1, with the lower opening of the injection channel facing the annular cavity area. Two circular first positioning holes are symmetrically opened on the left and right sides of the upper mold base 1. A second positioning hole is coaxially opened on the surface of the base plate 3 along the vertical direction, corresponding to the two first positioning holes. An annular insert groove is formed by a downward recess in the center of the base plate 3. Two cylindrical guide pillars are integrally formed on the upper surface of the lower mold base 2 plate. The guide pillars extend vertically upwards. During assembly, the two guide pillars pass through the second positioning hole of the base plate 3 and the first positioning hole of the upper mold base 1 from bottom to top to achieve a gap insertion fit. After the insertion is completed, the upper mold base 1, the base plate 3, and the lower mold base 2 remain coaxially locked without radial offset. A cylindrical boss is integrally formed on the center of the lower mold base 2 plate. Multiple rectangular through slots are evenly opened around the outer periphery of the boss on the lower mold base 2 plate, and the through slots completely penetrate the lower mold base 2 along the plate thickness direction. The cylindrical elastic silicone mold 4 is detachably embedded and fixed inside the annular embedding groove in the center of the base plate 3. A circular through hole is opened in the center of the elastic silicone mold 4 along the vertical direction, and the through hole matches the shape of the boss of the lower mold base 2. Several cylindrical micro holes are evenly opened on the upper end surface of the elastic silicone mold 4 along its own circumference, and the micro holes penetrate the upper and lower end surfaces of the elastic silicone mold 4 along the thickness direction.

[0027] The ring to be sealed is placed inside the elastic silicone mold 4, outside the boss area of ​​the lower mold base 2. The inner wall of the ring fits against the outer wall of the boss of the lower mold base 2, achieving full circumferential radial limitation. After the mold is closed, the outer wall of the boss of the lower mold base 2, the outer wall of the ring to be sealed, and the inner wall of the elastic silicone mold 4 are mutually spaced and enclosed to form a closed injection cavity with an annular cross-section. The lower opening of the injection channel that runs through the upper mold base 1 is directly connected to the top space of the annular cavity, serving as a dedicated passage for sealant feeding. The upper ends of the micro-holes arranged circumferentially on the elastic silicone mold 4 are connected to the top of the annular cavity, and the lower ends of the micro-holes are connected to the rectangular through grooves arranged around the boss of the lower mold base 2. The micro-holes and the through grooves of the lower mold base 2 are connected in series to form a complete and independent venting channel.

[0028] The upper mold base 1, lower mold base 2, and base plate 3 are made of steel and are integrally machined by CNC milling, with sufficient structural rigidity and are not prone to deformation due to long-term repeated mold closing; the elastic silicone mold body 4 is integrally molded with high elastic silicone, which has good sealing deformation capability and can be freely disassembled and replaced to adapt to different specifications of rings; the guide pillars and positioning holes adopt a small clearance fit, which takes into account both the convenience of assembly and disassembly and the coaxial positioning accuracy of the three-layer mold; the micro-pores opened on the elastic silicone mold body 4 can allow gas to pass through smoothly, while preventing the leakage of liquid sealant. This device adopts a three-layer split coaxial positioning structure consisting of an upper mold base 1, a base plate 3, and a lower mold base 2. It features independent injection and venting channels, eliminating the need to rely on mold assembly gaps for venting. The elastic silicone mold body 4 is detachable, facilitating quick replacement of mold cores to fit different ring sizes. The annular cavity has regular molding boundaries, ensuring smooth venting throughout the cavity while maintaining overall mold sealing and preventing leakage. This significantly reduces the rate of injection bubbles and is suitable for automated mass injection production of intelligent waterproof rings.

[0029] Example 2 This embodiment uses the device described in Embodiment 1, and is equipped with an automated system, which consists of four core units: a pressure detection module, a central control module, a quantitative dispensing module, and a pressure holding and sealing module. The pressure holding and sealing module contains two secondary components: a pneumatic control unit and a cylinder. The specific implementation process is as follows: The pressure detection module incorporates a high-precision cavity with a built-in pressure sensor, signal amplification circuit board, and analog signal output terminals. The pressure sensor probe extends into the annular cavity, directly contacting the gas and colloid inside to collect raw analog data of the pressure inside the sealed potting space in real time. The signal amplification circuit board performs noise reduction and amplification processing on the weak sensor signal. The output terminals are electrically connected to the signal input port of the central control module through shielded signal lines, ensuring no signal transmission attenuation and transmitting raw cavity pressure data to the central control module in real time.

[0030] The central control module is equipped with an industrial-grade single-chip controller, a data storage chip, a digital filtering and calculation unit, a threshold comparison unit, and multiple digital instruction output ports. The data storage chip pre-stores all process parameters, including negative pressure parameters, pressure change thresholds, air pressure ranges, micro-motion strokes, and curing time. The digital filtering and calculation unit has built-in first-order low-pass filter calculation logic, which is specifically used to process the raw pressure signal from the pressure detection module. The threshold comparison unit compares the pressure change rate with the preset threshold in real time. The multiple digital instruction output ports are independently connected to the quantitative dispensing module and the pneumatic control unit, which can issue different control commands synchronously or in shifts to achieve multi-device linkage and timing control.

[0031] The quantitative dispensing module includes a sealant storage tank, a precision metering pump, an electrically controlled on / off valve, and a sealant delivery pipeline. The end of the sealant delivery pipeline connects to the through-hole dispensing channel of the upper mold base 1. The electrically controlled on / off valve receives start and stop commands from the central control module. When the valve is open, the metering pump pushes the sealant into the cavity at a uniform speed. After receiving the stop command, the electrically controlled on / off valve instantly closes the pipeline, cutting off the sealant supply. The metering pump stops synchronously, accurately controlling the total amount of sealant injected and preventing excessive dispensing and overflow.

[0032] The pressure-holding and sealing module is an axial pressure application unit for the mold, integrating a pneumatic control unit and a cylinder as two linked components. The two are connected in a sealed manner through a high-pressure pneumatic pipeline. The pneumatic control unit includes a gas source pressure regulating valve, an electromagnetic reversing valve, a parameter storage chip, and a pulse output controller. The gas source pressure regulating valve is used to adjust the output gas pressure, achieving continuous adjustment from 0 to the rated gas pressure range. The electromagnetic reversing valve receives three types of commands from the central control module: pressure holding, pressure release, and micro-motion reciprocating, switching the cylinder's air intake and exhaust circuits. The parameter storage chip pre-stores the preset gas pressure range and preset micro-motion stroke parameters after calibration. The pulse output controller outputs a periodic alternating gas pressure signal to drive the cylinder to achieve low-amplitude, high-frequency reciprocating micro-motion. The cylinder adopts a double-acting standard linear cylinder. A flat pressure head is set at the top of the cylinder piston rod. The pressure head is in contact with the upper end face of the upper mold base 1, and the cylinder base is fixed below the lower mold base 2. The cylinder extends and holds pressure by relying on the constant air pressure output by the pneumatic control unit, and achieves small reciprocating extension and retraction by relying on alternating pulse air pressure. The axial pressure output by the cylinder acts perpendicularly on the central axis of the upper mold base 1 and the lower mold base 2 to ensure that the force is uniform on the entire mold contact surface. After the cylinder is fully retracted, the axial clamping force of the mold is completely released, and the mold can be opened directly to remove the part.

[0033] The standard diameter of the breathable micropores in the elastic silicone mold body is 0.3mm. The total cross-sectional area of ​​the micropores is equal to the cross-sectional area of ​​the groove around the lower mold base boss, ensuring airflow matching. The guide post and positioning hole adopt a standard clearance fit of H7 / g6. The inner diameter of the upper mold base injection channel is adapted to the output pipeline specifications of the metering pump. The precision reciprocating cylinder uses a CDJ2B miniature low-friction cylinder, the air pressure adjustment unit uses an SMC ITVX series electro-proportional valve, the displacement sensor uses a general magnetostrictive linear sensor, and the metering module is equipped with a micro-precision metering pump. All are industry-standard components. Multi-condition adaptation rules: When replacing with larger size ring products, the radial clearance of the annular cavity is widened and the injection delivery speed is increased. When using high-viscosity two-component sealant, the air pressure fluctuation range of 0.25-0.35MPa is widened to 0.23-0.37MPa, and the pre-vacuuming time is extended by 5s. When replacing with low-viscosity single-component sealant, the upper limit of the micro-motion stroke is compressed to 0.2mm to prevent the sealant from overflowing due to vibration. The complete solution fully discloses mold processing parameters, hardware selection, and operating condition adjustment rules. Mechanical and electrical control process personnel in the relevant fields can complete the entire process of mold processing, equipment assembly, and process debugging based on the text without additional creative work.

[0034] The production process of this embodiment is as follows: Figure 5 As shown, the specific implementation process is as follows: S1 Ring housing and coaxial alignment The cylindrical elastic silicone mold 4 is vertically embedded into the annular mounting groove in the center of the base plate 3 to complete the pre-installation positioning; a standard ring to be sealed is placed coaxially on the outside of the boss of the lower mold base 2 and inside the elastic silicone mold 4. The outer wall of the boss of the lower mold base 2 fits with the inner ring of the ring to achieve full circumferential positioning and prevent the ring from radially shaking and shifting; at this time, the outer wall of the boss of the lower mold base 2, the outer wall of the ring to be sealed, and the inner wall of the elastic silicone mold 4 are pre-enclosed to form an annular cavity blank space.

[0035] S2 Mold Closure Positioning and Pressure Holding Sealing The upper mold base 1 is moved downwards, so that the two guide pillars of the lower mold base 2 pass through the second positioning hole of the base plate 3 and the first positioning hole of the upper mold base 1 from bottom to top, completing the coaxial and precise mold closing of the three-layer mold of the upper mold base 1, the base plate 3, and the lower mold base 2; the pneumatic control unit in the pressure holding and sealing module is activated, and the pneumatic control unit adjusts the air source pressure regulating valve to output a constant air pressure to drive the cylinder to extend. The cylinder bearing head applies pressure to the end face of the upper mold base 1, and applies uniform axial pressure to the end faces of the upper mold base 1 and the lower mold base 2. The pressure is evenly transmitted along the central axis of the mold, compacting all the mold mating surfaces, and the annular cavity forms a completely sealed injection space; at this time, the lower end of the circumferential micropores of the elastic silicone mold body 4 is precisely connected to the through groove of the lower mold base 2, forming an exhaust channel connecting the annular cavity, and the lower end of the injection channel set through the upper mold base 1 is connected to the top of the annular cavity.

[0036] The axial reference holding pressure threshold is set based on the following: if the pressure is too low, there will be tiny gaps on the mold mating surface, and the glue will easily leak during the potting process; if the pressure is too high, the elastic silicone mold 4 will be excessively squeezed and deformed, resulting in the deviation of the annular cavity molding size. Therefore, a moderate reference holding pressure is selected as the standard working pressure.

[0037] S3 Pre-vacuuming to establish a negative pressure dispensing environment An external vacuum pump performs a vacuuming operation on the sealed potting space through the exhaust channel formed by the through groove of the lower mold base 2 and the micropores of the elastic silicone mold body 4. A fixed negative pressure threshold is set and the vacuuming is carried out for a preset time to completely remove the residual air at room temperature inside the annular cavity. The negative pressure threshold is set based on the following: if the negative pressure value is insufficient, the air inside the cavity cannot be fully discharged; if the negative pressure value is too high, it will cause the sealant to foam and deteriorate prematurely. Therefore, an intermediate suitable negative pressure value is selected as the standard negative pressure environment.

[0038] S4 Uniform speed dispensing and synchronous venting The central control module sends a start command to the quantitative dispensing module. The internal electrically controlled on / off valve of the quantitative dispensing module opens and the precision metering pump starts. The liquid sealant is uniformly delivered into the annular cavity through the dispensing channel set through the upper mold base 1, maintaining a fixed and uniform feeding state throughout the process. During the entire dispensing process, the air trapped inside the cavity and the gas generated by the heat volatilization of the sealant continuously pass through the micropores of the elastic silicone mold body 4 and the through groove of the lower mold base 2 to be discharged outward, maintaining a dispensing environment in which no gas is trapped inside the annular cavity throughout the process.

[0039] S5 Pressure Detection and Sealant Filling Status Identification The pressure detection module's built-in sensor collects real-time raw pressure data inside the sealed potting space. After noise reduction by the onboard amplification circuit, the data is transmitted to the central control module via a shielded signal cable. The central control module's internal digital filtering unit performs first-order low-pass filtering calculations. The filter MD formula is: In the formula: The pressure data is after filtering, in kPa. Real-time raw pressure data, unit kPa; filter coefficients. Take a fixed constant; This is the moment when pressure is collected.

[0040] Based on the filtered pressure data, the pressure change rate is calculated using the following formula: In the formula: The pressure change rate is expressed in kPa / s. The sampling interval is fixed.

[0041] The threshold comparison unit of the central control module retrieves the fixed pressure change threshold pre-stored in the memory chip. If the pressure change rate calculated in real time is greater than the preset threshold, the central control module determines that the annular cavity has been completely filled with sealant, generates a filling completion trigger signal synchronously, and sends corresponding timing instructions to the quantitative dispensing module and the pressure holding and sealing module.

[0042] In this embodiment, referring to the calibration format of air pressure range and micro-motion stroke, two sets of gradient comparison tests were added: negative pressure threshold and axial reference holding pressure. Three sets of gradient tests were conducted for the negative pressure range: -0.05MPa, -0.08MPa, and -0.1MPa, with -0.08MPa selected as the standard negative pressure. Three sets of gradient tests were conducted for the reference holding pressure: 0.2MPa, 0.3MPa, and 0.4MPa, to determine the standard static holding pressure value of 0.3MPa. This ensures that all pressure parameters have a quantitative experimental basis. A first-order low-pass filter is used to filter out high-frequency pressure noise generated by pneumatic equipment disturbances. The pressure change rate is determined based on the fluid characteristics of the gas channel closing and pressure rapidly rising after the adhesive fills the cavity. Dynamic air pressure fluctuation defoaming utilizes the fluid dynamics law of the rupture of bubbles under pressure inside the colloid.

[0043] S6 Stop potting and pressure curing After receiving the filling completion trigger signal, the central control module sends a dispensing stop command to the dispensing module. Upon receiving the command, the dispensing module instantly closes the sealant pipeline with the electronic on / off valve, and the precision metering pump stops simultaneously, immediately terminating the sealant dispensing operation. The central control module simultaneously sends a pressure maintenance command to the pneumatic control unit in the pressure holding and sealing module.

[0044] The pneumatic control unit retrieves preset air pressure ranges and preset stroke ranges from its internal storage chip, adapted to the curing characteristics of the current batch of sealant. The internal pulse output controller of the pneumatic control unit outputs periodically alternating air pressure signals, which, in conjunction with the solenoid directional valve, switch the air path to drive the cylinder to perform low-frequency, low-amplitude reciprocating micro-motion. The cylinder's reciprocating motion has a fixed cycle. During the cylinder's micro-motion, the pressure inside the annular cavity fluctuates regularly within the preset air pressure range, repeatedly squeezing and breaking up micron-sized residual bubbles inside the sealant. The cylinder's micro-stroke generates uniform, slight mechanical vibration, causing incompletely broken micro-bubbles to continuously accumulate on the sealant surface. This preset air pressure range and preset micro-stroke will not deform the annular sealant layer or cause eccentric displacement of the internal ring. After the preset curing time is maintained, and the sealant has completed initial curing, the pneumatic control unit switches the solenoid directional valve to release pressure, controlling the cylinder to fully retract and complete the pressure relief.

[0045] The central control module's digital filtering and processing unit, equipped with a hardware ADC chip, has a fixed sampling period Δt=0.1s and a filtering coefficient α=0.1, calibrated through multiple sets of noise comparison tests under various potting conditions. This coefficient effectively filters out pressure noise caused by vacuum pump start-up and shutdown, and cylinder micro-movements. After filtering, all pressure timing data is stored in the module's built-in FIFO buffer, automatically performing a pressure change rate calculation every 0.1s. Pressure change threshold. Without relying on manual experience for setting, a gradient filling calibration method is used: pressure change curves are collected under multiple no-load, half-fill, and fully-fill conditions. The critical pressure change value at the moment the adhesive completely fills the cavity is extracted as a threshold and pre-stored in the memory chip. When changing to sealants with different viscosities or formulations, iterative calibration is required. The internal pulse output controller of the pneumatic control unit outputs a sinusoidal alternating air pressure signal. The reciprocating motion cycle of the cylinder is fixed at 1 second, and the air pressure rise and fall rate is controlled at 0.02 MPa / s. Smooth air pressure changes can avoid instantaneous impact and agitation of the adhesive, and the generation of new bubbles. The dynamic pressure holding and curing time of the sealant is matched with temperature gradient calibration rules. The baseline ambient temperature condition is set at 8 minutes; when the ambient temperature is higher than 35℃, the cross-linking speed of the adhesive is accelerated, and the curing time is reduced to 5-6 minutes; when the ambient temperature is lower than 15℃, the adhesive curing is slow, and the curing time is extended to 10-12 minutes.

[0046] In this embodiment, the preset air pressure range was calibrated through multiple sets of iterative comparative tests: samples of epoxy sealant from the same batch were selected, and rheological parameters and curing stress parameters corresponding to the four stages of colloid heating and melting, colloid filling, preliminary curing, and shaping and hardening were collected; combined with the size parameters of the annular cavity structure formed by the upper mold base 1, lower mold base 2, substrate plate 3, and elastic silicone mold 4, five sets of constant reference air pressures of 0.1MPa, 0.2MPa, 0.3MPa, 0.4MPa, and 0.5MPa were set sequentially by adjusting the air source pressure regulating valve of the pneumatic control unit. Parallel tests were conducted by superimposing ±0.05MPa fluctuation amplitude under each set of air pressures, and the appearance of the adhesive layer and the internal defoaming effect were compared under each set of air pressures.

[0047] The test results are as follows: At a baseline air pressure of 0.1 MPa and a fluctuation range of 0.05-0.15 MPa, the pressure fluctuation amplitude was insufficient, and the 15 μm diameter microbubbles inside the colloid could not be broken, resulting in a bubble defect rate exceeding 18% in the finished product. At a baseline air pressure of 0.4 MPa and a fluctuation range of 0.35-0.45 MPa, and at a 0.5 MPa fluctuation range of 0.45-0.55 MPa, the pressure was too high, causing compression deformation of the elastic silicone mold 4, collapse and glue overflow on both sides of the annular adhesive layer, and a coaxial offset of the ring exceeding 0.04 mm. Under a baseline air pressure of 0.3 MPa and a fluctuation range of 0.25 MPa~0.35 MPa, the adhesive layer was formed smoothly without collapse or glue overflow, and the micron-sized bubbles inside the cavity were completely broken, reducing the bubble defect rate to below 0.5%. Therefore, 0.25 MPa~0.35 MPa was selected as the optimal air pressure range, and this range was solidified and written into the pneumatic control unit parameter storage chip for direct use in mass production.

[0048] In this embodiment, the preset stroke range is obtained through multi-gradient comparative test calibration: using the mold composed of the upper mold base 1, lower mold base 2, base plate 3, and elastic silicone mold 4 provided in this embodiment, combined with the structural parameters of the annular cavity depth and the thickness of the molding adhesive layer, the alternating air pressure amplitude of the pulse output controller of the pneumatic control unit is adjusted, and six levels of cylinder micro-motion stroke of 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, and 0.6mm are set respectively for comparative testing.

[0049] Examples of test results: When the micro-motion stroke is 0.05mm, the mechanical vibration energy is insufficient, and air bubbles inside the colloid cannot migrate to the surface, leaving dense micropores inside the colloid layer after curing. When the micro-motion stroke is 0.4mm and 0.6mm, the cylinder's return-to-reset amplitude is too large, and each micro-motion pushes the ring to produce radial displacement, with a maximum displacement of 0.06mm. At the same time, compression wrinkles and interface loosening defects appear at the edge of the colloid layer. Under the three working conditions of micro-motion strokes of 0.1mm, 0.2mm, and 0.3mm, the mold fitting state is stable, the ring has no eccentric displacement, and the vibration can drive all micro-bubbles to migrate to the surface of the colloid layer, with no bubble defects after polishing. Considering the overall molding stability and defoaming efficiency, 0.1mm~0.3mm is selected as the optimal micro-motion stroke range. This range is solidified and pre-stored in the pneumatic control unit's storage chip for standardized mass production.

[0050] This method relies on a three-layer coaxial mold dual-channel structure consisting of an upper mold base 1, a base plate 3, and a lower mold base 2, combined with negative pressure pre-venting and uniform speed synchronous venting processes. The entire control system has clearly defined functions for each module, with precise linkage timing. The pressure detection module accurately collects the cavity pressure, the central control module performs signal filtering and intelligent judgment of the filling status, the quantitative dispensing module instantly cuts off the sealant supply, and the pressure holding and sealing module relies on the pneumatic control unit and cylinder to achieve static pressure stabilization and dynamic micro-motion defoaming dual modes. In the curing stage, a small-amplitude dynamic pressure stabilization process calibrated through multi-gradient numerical tests is adopted, relying on controllable pressure fluctuations and micro-vibrations to remove trace amounts of hidden air bubbles that cannot be removed by conventional static pressure holding. The entire process is fully automated and linked, with parameters precisely matched to the curing characteristics of the sealant, while taking into account both mold sealing performance and efficient venting capabilities. The molded adhesive layer is dense and bubble-free, effectively improving the waterproof rating of the smart waterproof ring. The batch production process is uniform and consistent, reducing the cost of manual on-site debugging and the product defect rate.
