The floating pressing assembly comprises a pressing sleeve, a main pressing rod, a position-adjusting pressing rod which can be adjusted relative to the main pressing rod, a pressing block and a locking piece. When the position-adjusting pressing rod is not locked, it can automatically adjust the position according to the peripheral contour of the assembly, and can be locked after the standard assembly is calibrated. The liquid cavities of the pressing sleeves are communicated with the liquid collecting cavity. The working liquid discharged by the liquid cavities is collected into the liquid collecting cavity by the main pressing rod, and the first-stage overall pressing stroke is verified by the liquid level identification part. After the liquid level continues to rise, the working liquid drives the auxiliary processing assembly through the high-position flow guide part, so that the impact part periodically impacts the auxiliary pressing part, so as to promote the spreading of the glue layer and the migration of the trapped air.

Description

Technical Field

[0001] This invention belongs to the field of smart screen module assembly technology, specifically a floating pressing device for smart screen modules. Background Technology

[0002] When assembling smart screen modules, pressure needs to be applied to the periphery of the frame using a pressing device to cure the adhesive layer and expel air between the display components and the frame, thus avoiding defects such as bubbles and warping.

[0003] Existing pressing equipment mostly uses fixed-height pressure heads or independent spring pressure heads to apply pressure to the periphery of the assembly. When there are uneven contours around the assembly, fixed-height pressure heads cannot adapt to the actual height differences at various points, which can easily lead to excessive force in some areas, damaging the display components, while insufficient force in other areas results in incomplete pressing. Although independent spring pressure heads can adapt to height differences to a certain extent, the pressure applied to the assembly varies due to the different spring compressions of each pressure head, making it difficult to ensure consistent force at all points around the periphery.

[0004] Meanwhile, existing pressing equipment typically requires displacement or pressure sensors at each pressing point to determine whether the pressing stroke is within the acceptable range and whether the assembly is flat or within the preset contour. The number of sensors increases with the number of pressing points, increasing equipment cost and wiring complexity. Furthermore, their reliability is limited in long-term use in environments with high levels of adhesives and dust. In addition, to further remove residual air between the display assembly and the adhesive, some equipment is equipped with a vibration motor to apply auxiliary vibration to the edges of the assembly. The start and stop timing of this motor relies on an independent electrical control system, lacking an inherent linkage with the main pressing progress. This poses a risk that vibration may be applied to the assembly before it is properly pressed.

[0005] Therefore, how to make the pressing equipment adapt to the high and low contours of the assembly periphery and ensure uniform force, while realizing sensorless determination of the pressing state and automatic linkage between auxiliary venting action and pressing progress, is a technical problem to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to provide a floating pressing device for smart screen modules, so as to solve the problems of existing pressing devices that are difficult to balance the adaptability of different peripheral contours and the uniformity of pressing force, the need to set detection elements at multiple pressing positions, and the difficulty of the auxiliary venting action to start in a timely manner with the main pressing process.

[0007] To achieve the above objectives, the present invention provides a floating pressing device for smart screen modules, including a supporting component, a lifting mechanism, and a pressing seat driven by the lifting mechanism. The supporting component is used to support the smart screen assembly to be pressed, and the pressing seat is provided with a plurality of floating pressing components facing the smart screen assembly to be pressed. Each floating pressing component includes a pressing sleeve, a main pressing rod slidably disposed in the pressing sleeve, an adjusting pressing rod movably disposed at the lower part of the main pressing rod along the pressing direction, and a pressing block disposed at the lower end of the adjusting pressing rod; a first elastic element is provided between the main pressing rod and the pressing sleeve, and a locking element is provided between the adjusting pressing rod and the main pressing rod, so that the adjusting pressing rod switches between an active state and a locked state.

[0008] When the locking mechanism is released, each adjusting pressure bar can move relative to the main pressure bar according to the actual height of the position to be pressed, allowing multiple pressure blocks to adapt to the height differences around the perimeter of the smart screen assembly to be pressed. After the contour calibration is completed using standard assembly parts, the locking mechanism holds each adjusting pressure bar in its corresponding position, so that multiple pressure blocks form a height combination that matches the preset perimeter contour. As the pressing seat continues to descend, the pressure blocks transfer the load to the main pressure bar via the adjusting pressure bars, and the first elastic element forms an elastic pressing effect, thus allowing the contour adaptation process and the formal pressing process to proceed sequentially.

[0009] The pressing seat contains a fluid collection chamber, and multiple pressing sleeves each form a fluid chamber whose volume changes as the main pressing rod moves. Each fluid chamber is connected to the fluid collection chamber. During the first stage of pressing, the main pressing rod compresses the corresponding fluid chamber, causing the working fluid discharged from multiple fluid chambers to flow into the fluid collection chamber. The fluid level changes are displayed through a fluid level observation window located on the side of the fluid collection chamber. The fluid level observation window is equipped with a fluid level indicator. By checking whether the working fluid reaches the fluid level indicator, the total effective pressing stroke generated by the multiple main pressing rods is verified to preliminarily determine whether the smart screen assembly to be pressed has significantly deviated from the target flatness or preset contour.

[0010] The upper part of the manifold is connected to a high-level guide section, the inlet of which is higher than the level indicator. After the pressing seat completes the first stage of pressing, it continues to descend, and the level in the manifold exceeds the inlet of the high-level guide section. The newly discharged working fluid enters the flow drive section through the high-level guide section. Thus, a sequential control based on the level height is established between the level indicator and the high-level guide section, enabling auxiliary processing actions to be initiated after the overall pressing status of the first stage is verified.

[0011] The pressing base is also equipped with auxiliary processing components, including an auxiliary pressing component facing the smart screen assembly to be pressed, a support portion for elastically moving the auxiliary pressing component along the pressing direction, an impact component movably disposed within the support portion, and a vibration generating portion driven by liquid supply from a high-level guide portion. Under the action of the working fluid, the vibration generating portion periodically drives the impact component away from the auxiliary pressing component and periodically releases the drive on the impact component, causing it to fall back and impact the auxiliary pressing component. The auxiliary pressing component transmits repeated impacts while maintaining contact with the periphery of the smart screen assembly to be pressed, thereby superimposing axial pressure pulsations on the continuous pressing load, promoting adhesive layer spreading and the migration of air trapped between the display assembly and the adhesive layer.

[0012] In one alternative embodiment, the impactor is a ferromagnetic metal ball disposed within an auxiliary sleeve, and the vibration generating unit includes a rotating disk equipped with multiple magnetic attractors. As the rotating disk rotates, the multiple magnetic attractors sequentially enter and exit their magnetic attraction positions on the metal ball, causing the metal ball to repeatedly complete the lifting, releasing, and falling impact. The fluid drive unit can convert the linear motion generated by the working fluid into the rotation of the rotating disk via a transmission rod, toothed plate, and gears, allowing the multiple magnetic attractors to sequentially pass through their magnetic attraction positions within a shorter pressing stroke in the second stage.

[0013] The beneficial effects of this invention are as follows: 1. This invention provides a movable and selectively lockable adjustment rod at the lower part of the main pressure rod, so that multiple pressure blocks can adapt to the actual height of the periphery of the smart screen assembly before formal elastic pressing. The preset contour can be calibrated by standard assembly to form a reusable contour, avoiding load concentration or insufficient pressing caused by local height differences when the fixed height pressure head is directly pressed.

[0014] 2. This invention collects the liquid discharge from multiple pressing positions into the same liquid collection chamber and performs overall verification of the total effective pressing stroke of multiple main pressure rods by liquid level changes. It eliminates the need to set displacement detection elements or pressure detection elements at each pressing position, which helps to simplify the equipment structure and on-site wiring. It can also screen out assemblies with obviously abnormal overall pressing status before entering subsequent auxiliary pressing.

[0015] 3. In this invention, the inlet of the high-level guide section is set above the liquid level indicator section, so that the first-stage liquid level verification and subsequent auxiliary processing are sequential in the liquid flow path; only after the liquid level passes the high-level guide section will the working fluid drive the vibration generator to operate, thereby using the hydraulic changes generated by the pressing process itself to realize the mechanical linkage between the auxiliary processing and the main pressing process, reducing the dependence on independent vibration power sources and complex electrical control systems.

[0016] 4. This invention utilizes an impactor to repeatedly impact the auxiliary pressing component of the elastic support, creating pressure pulsations on the peripheral adhesive layer without directly impacting the display screen assembly. This promotes the spreading of the adhesive layer and the migration of trapped air to the edge. As the auxiliary pressing component gradually retracts during the pressing process, the effective falling stroke of the impactor can be reduced accordingly, so that the auxiliary effect gradually changes from stronger in the early stage to weaker in the later stage, taking into account both the auxiliary venting effect and product protection at the end of the pressing process.

[0019] The following is combined Figures 1 to 10 The structural composition, fit, and working process of this application are further explained. The accompanying drawings illustrate the connections, movements, and fluid communication between the components. The number, size, and spacing of each component can be adjusted according to the external dimensions of the smart screen assembly 100 to be pressed, the peripheral bonding area, the type of adhesive layer, and the target pressing pressure. The floating pressing method referred to in this application means that multiple pressing blocks 45 adapt to the height of their respective pressing positions before establishing the main pressing load. After reaching a predetermined contact state, a continuous pressing force is formed by the main pressing rod 42 and the first elastic element 43. The first-stage pressing method referred to in this application refers to the process of verifying the pressing state using the total amount of liquid discharged from the multiple main pressing rods 42. The second-stage pressing method refers to the process of continuing to discharge liquid with a smaller vertical stroke after verification, and using this portion of liquid to drive the auxiliary processing component 6 to perform repeated micro-impacts. Subsequently, the pressing seat 3 stops descending and enters static pressure holding.

[0020] In one embodiment, the smart screen module floating pressing device includes a bearing component 1, a lifting mechanism 2, a pressing base 3, multiple floating pressing components 4, a fluid collection chamber 5, an auxiliary processing component 6, and a transmission component 7. The bearing component 1 includes a base 11, multiple support rods 12 fixed to the base 11, and positioning seats 13 respectively disposed on the upper end of the support rods 12. The multiple positioning seats 13 together form a rectangular bearing area. The smart screen assembly 100 to be pressed includes a frame and a display screen assembly predetermined to be located within the frame. The positioning seats 13 mainly support the area of ​​the frame that does not need to undergo significant deformation, so that the pressing reaction force is transmitted to the base 11 through the frame, avoiding the central display area of ​​the display screen assembly from directly bearing the concentrated load. The positioning seats 13 may be provided with a stepped support surface, a support surface adapted to the local contour of the bottom of the frame, and a lateral limiting surface. The position where the positioning seats 13 contact the frame may be provided with a pad layer of polyoxymethylene, polyurethane, silicone, or other materials that are not easy to scratch the surface of the frame.

[0021] The lifting mechanism 2 includes a mounting frame 21 and a lifting drive component 22 mounted on the mounting frame 21. Connecting plates 31 are respectively provided on opposite sides of the pressing seat 3, and the connecting plates 31 are connected to the movable end of the lifting drive component 22. The lifting drive component 22 can be a hydraulic cylinder, pneumatic cylinder, electric push rod, or servo screw mechanism, which drives the pressing seat 3 to move closer to or away from the bearing component 1 along the pressing direction. The pressing seat 3 can be a steel box, an aluminum alloy box, or a plate structure with reinforcing ribs to limit the central deflection of the pressing seat 3 under large spans. The deformation of the pressing seat 3 itself should be less than the allowable product contour deviation to avoid the structural deformation of the pressing seat 3 being mistakenly identified by the liquid level verification structure as an abnormality in the smart screen assembly 100 to be pressed.

[0022] Multiple floating pressing components 4 are installed on the lower part of the pressing base 3 and spaced apart along the periphery of the smart screen assembly 100 to be pressed. The floating pressing components 4 can be mainly arranged at the corners of the frame, the middle of the long side, and the positions where the local stiffness changes. An installation interval is maintained between adjacent floating pressing components 4 so that each pressing block 45 can respond to the height of its corresponding position, rather than the load on a certain local high point being directly transferred to the adjacent low point by a whole rigid pressing plate. The number of floating pressing components 4 is determined according to the size of the smart screen assembly 100, the frame stiffness, and the adhesive layer width. Without changing the working mechanism, they can be arranged in a ring around the periphery of the rectangle, or pressing points can be added in the long side area.

[0023] like Figure 3 and Figure 4As shown, each floating pressing assembly 4 includes a pressing sleeve 41, a main pressing rod 42, a first elastic element 43, an adjusting pressing rod 44, a pressing block 45, a locking element 46, an assembly cavity 47, and a limiting ring 48. The pressing sleeve 41 is fixed to the pressing seat 3. The main pressing rod 42 is slidably disposed inside the pressing sleeve 41 along the pressing direction. One end of the main pressing rod 42 extending into the pressing sleeve 41 is provided with a sealing head 421, which slides and seals against the inner wall of the pressing sleeve 41. The space on the side of the sealing head 421 away from the pressing block 45 forms a liquid cavity, which is connected to the liquid collection cavity 5 through a liquid communication port 54. When the main pressing rod 42 is pressed and moves towards the inside of the pressing sleeve 41, the sealing head 421 reduces the volume of the liquid cavity and discharges the working fluid into the liquid collection cavity 5. After the external load is released, the first elastic element 43 drives the main pressing rod 42 to reset, and the working fluid returns to the liquid cavity along the original communication path.

[0024] The sealing head 421 can be equipped with one or more sets of annular sealing grooves, and O-rings, Y-rings, U-rings, or combinations of seals can be installed in the sealing grooves. When the working fluid is mineral-based low-viscosity hydraulic oil, the seals can be made of nitrile rubber or polyurethane; when the working fluid is water-glycol, the seals can be made of EPDM rubber; when the equipment is used in a high-temperature hot pressing station, the seals can be made of fluororubber. The inner wall of the pressing sleeve 41 can be precision machined, honed, hard anodized, or hard chrome plated. The main pressure rod 42 can be made of stainless steel or surface-hardened alloy steel to reduce friction and wear during reciprocating motion. The material selection should be matched with the working fluid and the actual temperature of the equipment to avoid changes in the discharge volume due to swelling, hardening, or shrinkage of the seals.

[0025] The lower part of the main pressure rod 42 is provided with an assembly cavity 47. A limiting ring 48 is fixed to the lower part of the assembly cavity 47, and the adjusting pressure rod 44 moves through the limiting ring 48. One end of the adjusting pressure rod 44 located in the assembly cavity 47 is provided with a slider 441, and the other end is connected to the pressure block 45. The slider 441 is located between the limiting ring 48 and the top wall of the assembly cavity 47. The slider 441 and the assembly cavity 47 adopt a clearance sliding fit. The assembly cavity 47 is connected to the outside through the assembly gap between the adjusting pressure rod 44 and the limiting ring 48, the vent hole provided in the main pressure rod 42, or the longitudinal vent groove. Thus, when the slider 441 moves, the air on both sides can be exchanged, and no additional closed air pressure will be formed in the assembly cavity 47, avoiding interference from the free conformation of the adjusting pressure rod 44 and subsequent liquid level verification.

[0026] When the pressing seat 3 is in the raised position and the locking member 46 is not locked, the adjusting pressure rod 44 and the pressure block 45 move downward under their own weight, and the slider 441 approaches the limiting ring 48. After the pressing seat 3 descends, each pressure block 45 contacts the product sequentially according to the actual height of the corresponding position of the smart screen assembly 100. After contact, the adjusting pressure rod 44 moves upward relative to the main pressure rod 42 until the slider 441 abuts against the top wall of the assembly cavity 47. The stroke of the slider 441 from the position near the limiting ring 48 to the top wall of the assembly cavity 47 is mainly used to eliminate the difference between the initial height of the pressure block 45 and the local height of the product. Before the slider 441 abuts against the top wall of the assembly cavity 47, the first elastic member 43 basically does not apply the main pressing load to the pressing position, thereby reducing the possibility of the first contacting pressure block 45 causing premature concentrated force on the local area.

[0027] The locking component 46 includes a locking tube 461 fixed to the side of the main pressure rod 42 and a locking bolt 462 threaded to the locking tube 461. The main pressure rod 42 and the limiting ring 48 are respectively provided with locking holes through which the locking bolt 462 passes. After the end of the locking bolt 462 presses against the adjusting pressure rod 44, the relative position of the adjusting pressure rod 44 and the main pressure rod 42 is maintained. A flat pressing section can be provided on the side of the adjusting pressure rod 44 opposite to the locking bolt 462. The pressing end of the locking bolt 462 can be provided with a copper, polyoxymethylene, or anti-slip textured pressure head to limit the rotation of the adjusting pressure rod 44 during locking and reduce pressure damage to the surface of the adjusting pressure rod 44 by the pressing end. In batch use, the tightening degree of each locking bolt 462 can be controlled by a torque limiting knob to ensure consistent locking states at different pressing points.

[0028] When the target periphery of the smart screen assembly 100 to be pressed is on the same reference plane, all locking bolts 462 remain loose. Multiple pressure blocks 45 first contact the product in a free state, and then the slider 441 abuts against the top wall of the assembly cavity 47 to establish an axial force transmission relationship. When the product's local position is higher, the corresponding slider 441 abuts against the top wall of the assembly cavity 47 earlier, and the main pressure rod 42 forms a larger effective retraction stroke before the pressing seat 3 reaches the first stage position; when the product's local position is lower, the corresponding slider 441 abuts against the top wall of the assembly cavity 47 later, and the main pressure rod 42 forms a smaller effective retraction stroke. Thus, the local height difference around the product's periphery is converted into a difference in the drainage stroke of the multiple main pressure rods 42.

[0029] When the same batch of smart screen components 100 has a predetermined peripheral height profile, multiple adjusting pressure rods 44 can be calibrated first using standard components. Specifically, the standard components are placed on the positioning seat 13, and the pressing seat 3 is controlled to descend at a low speed, so that each pressure block 45 contacts the corresponding position of the standard component, and the pressing seat 3 stops at a position where all pressure blocks 45 have contacted but the first elastic element 43 has not yet generated a significant main pressing load. At this time, each adjusting pressure rod 44 stops at a different height according to the peripheral profile of the standard component, and each pressure block 45 mainly applies its own weight and a small contact preload to the standard component, making it difficult for the standard component to deform significantly due to the calibration load. Then, each locking bolt 462 is tightened to fix the position of each adjusting pressure rod 44 relative to the main pressure rod 42. After the pressing seat 3 rises and the standard component is removed, subsequent products in the same batch can directly use the already formed pressure block height combination to make each pressure block 45 reproduce the standard peripheral profile, and then the first elastic element 43 completes the subsequent elastic pressing.

[0030] An elastic contact pad can be provided at the lower end of the pressure block 45. For room temperature pressing, the elastic contact pad can be made of silicone, thermoplastic polyurethane, or EPDM rubber with a Shore A hardness of 30 to 60. For pressing at higher temperatures, high-temperature resistant silicone or fluorosilicone rubber can be used, and a polyimide film or a thin layer of polytetrafluoroethylene can be applied to the surface in contact with the product to reduce adhesive adhesion. The contact area of ​​the pressure block 45 is determined based on the width of the peripheral bonding area, and the contact surface should avoid the display area and weak points susceptible to concentrated stress damage. The thickness and hardness of the elastic contact pad should be sufficient to compensate for minor surface errors without causing significant lateral sway of the pressure block 45.

[0031] like Figure 5 and Figure 6 As shown, the fluid collection chamber 5 is located within the pressure seat 3, and the fluid chambers of multiple pressure sleeves 41 are connected to the fluid collection chamber 5 through fluid communication ports 54. The fluid collection chamber 5 is filled with working fluid, which can be low-viscosity hydraulic oil, water-glycol liquid, low-viscosity silicone oil, or other liquids that maintain stable fluidity within the equipment's operating temperature range and are compatible with the seals, and are within the ISO VG15 to VG32 range. Excessive working fluid viscosity will reduce the response speed of the second stage, and large air bubbles remaining in the working fluid will absorb the discharge volume of the main pressure rod 42. Therefore, after initial use of the equipment, replacement of the working fluid, or replacement of the seals, fluid should be slowly injected from a low position and air should be vented from a high position to ensure that no large air bubbles remain in the fluid chambers, fluid communication ports 54, fluid collection chamber 5, and drive channels that require fluid filling, thus preventing large air bubbles from affecting fluid level changes and transmission stroke.

[0032] The side wall of the fluid collection chamber 5 is provided with a liquid level observation window 53, which communicates with the liquid inside the fluid collection chamber 5. In equipment operating at normal temperatures, the liquid level observation window 53 can be made of polycarbonate, polymethyl methacrylate, transparent nylon, or borosilicate glass; at higher temperatures, borosilicate glass or heat-resistant transparent engineering plastics can be used. When the pressing seat 3 is a metal structure, the observation window can be fixed by a pressure plate, O-ring, and sealing gasket, or it can be sealed with structural adhesive compatible with the working fluid. When both the pressing seat 3 and the observation window are made of weldable thermoplastic materials, ultrasonic welding or hot plate welding can be used to form a sealed connection. For locations subjected to hydraulic pressure and repeated temperature changes, ordinary hot melt adhesive should not be used as a long-term sealing material.

[0033] A liquid level indicator 51 is disposed on the liquid level observation window 53. The liquid level indicator 51 can be a stencil, raised line, groove, or a marker fixed to the outside of the observation window. The liquid level indicator 51 can be set as a single target line or as an allowable range with upper and lower limits. After the equipment is installed, a complete first-stage pressing can be performed using standard fittings that meet the requirements. The marking position is determined based on the stable liquid level when the pressing seat 3 is in the predetermined first-stage position. Different sizes or products with different preset contours can correspond to different marking lines, and the standard fittings can be recalibrated after changing the product specifications.

[0034] As multiple main pressure rods 42 move, the working fluid discharged from each sealing head 421 flows into the same collection chamber 5, thus converting the effective displacement of multiple dispersed pressing positions into the total discharge volume and corresponding liquid level. This liquid level verification is mainly used for rapid coarse screening before entering a larger pressing load. When the liquid level is significantly lower than the target range, it may indicate that some pressing blocks 45 have not reached the predetermined contact state, the product is partially sunken, the component position is offset, or the preset contour is mismatched; when the liquid level is significantly higher than the target range, it may indicate that the product is partially protruding, foreign objects are trapped, the initial liquid level is too high, or the descent position of the pressing seat 3 is abnormal. Since the positive and negative deviations at different positions may cancel each other out, the liquid level verification is not used to determine the specific location of the defect, nor does it replace high-precision flatness detection. Its function is to screen out the parts to be pressed that have significantly abnormal total effective displacement.

[0035] The high-level guide section 52 includes a top flow channel 521 and a connecting pipe 522. The inlet of the top flow channel 521, which connects to the liquid collection chamber 5, is at a height higher than the liquid level indicator section 51. When the pressing seat 3 descends to the first stage position and the liquid level reaches the liquid level indicator section 51, the working fluid has not yet passed the inlet of the high-level guide section 52, and the transmission component 7 does not generate effective drive. Only after the verification is passed will the pressing seat 3 continue to perform the second stage short-stroke compression, and the liquid level in the liquid collection chamber 5 will rise further and reach the inlet of the high-level guide section 52. Only then will the newly added working fluid enter the top flow channel 521 and the connecting pipe 522. The height difference between the liquid level indicator section 51 and the inlet of the high-level guide section 52 corresponds to a liquid reserve. This liquid reserve is used to absorb the effects of liquid surface sloshing, manufacturing errors, and short-term inertia, so that the auxiliary processing component 6 will not be activated immediately when the liquid level just reaches the verification position. Thus, the mechanical sequence constraint of verification first and activation later is formed by the flow channel height relationship.

[0036] To reduce the impact of residual air in the high-level guide section 52 and transmission assembly 7 on the second-stage stroke, a test vent can be installed at the high position of the guide pipe 522 or the transverse sleeve 71. During the initial liquid injection, the vent should be closed after continuous liquid flow to keep the guide pipe 522 and drive chamber filled with liquid. A breathing structure can be installed above the liquid inlet of the high-level guide section 52 in the upper part of the liquid collection chamber 5. The breathing structure uses a liquid-repellent and breathable membrane or a splash-proof ventilation channel to keep the gas phase space above the liquid collection chamber 5 close to atmospheric pressure, preventing the first-stage liquid discharge from being used only to compress the closed air and changing the correspondence between the liquid level and the discharge volume. The position of the breathing structure should prevent the working fluid from entering within the normal liquid level range.

[0037] like Figures 7 to 9 As shown, the auxiliary processing component 6 is disposed between multiple floating pressing components 4, and may include two support branches distributed along opposite sides of the smart screen assembly 100. Each support branch includes an auxiliary push rod 61, an auxiliary sleeve 621, a second elastic element 622, a metal ball 64, a rotating disk 631, multiple magnetic suction elements 632, a rotating shaft 633, and a positioning tube 634. The auxiliary push rod 61 is slidably disposed on the auxiliary sleeve 621, with its lower end facing the peripheral non-display area of ​​the smart screen assembly 100, and may be provided with a flexible contact head made of silicone or polyurethane. The second elastic element 622 is disposed between the auxiliary sleeve 621 and the auxiliary push rod 61, so that the auxiliary push rod 61 can retract relative to the auxiliary sleeve 621 and continuously adhere to the product when the pressing seat 3 descends, while buffering the instantaneous impact generated by the metal ball 64, preventing rigid impact from directly acting on the display assembly.

[0038] The metal ball 64 is movably disposed within the auxiliary sleeve 621 and located above the impact end of the auxiliary push rod 61. The metal ball 64 is made of a ferromagnetic material that can be attracted by the magnetic attractant 632, such as GCr15 bearing steel, low-carbon steel, or ferromagnetic martensitic stainless steel. The wall of the auxiliary sleeve 621 corresponding to the moving area of ​​the magnetic attractant 632 is made of aluminum alloy, brass, polyoxymethylene, polyetheretherketone, austenitic stainless steel, or other non-magnetic materials with minimal impact on magnetic force. A non-magnetic thin-walled isolation section may also be provided at the corresponding position of the metal sleeve. A low-friction liner may be provided on the inner wall of the auxiliary sleeve 621, and a sufficient gap is left between the metal ball 64 and the auxiliary sleeve 621 to ensure free lifting and lowering without significant lateral movement.

[0039] The rotating disk 631 is rotatably mounted on the side of the auxiliary sleeve 621 via a rotating shaft 633 and bearings within the positioning tube 634. Multiple magnetic attractors 632 are spaced apart circumferentially along the rotating disk 631. Under normal temperature conditions, the magnetic attractors 632 can be neodymium iron boron permanent magnets; under hot pressing conditions, neodymium iron boron magnets or samarium cobalt magnets with higher temperature resistance can be used. When the magnetic attractor 632 passes through the predetermined magnetic attraction area of ​​the auxiliary sleeve 621, its attractive force on the metal ball 64 is greater than the weight and resistance of the metal ball 64, causing the metal ball 64 to move away from the auxiliary push rod 61. After the magnetic attractor 632 leaves the area, the magnetic force decreases, and the metal ball 64 falls back under gravity and impacts the impact end of the auxiliary push rod 61. A non-magnetic gap is maintained between adjacent magnetic attractors 632, allowing the metal ball 64 time to complete release, fall, and impact, thus preventing the next magnetic attractor 632 from prematurely attracting the metal ball 64 again before it has fallen to the impact end.

[0040] The transmission assembly 7 includes a transverse sleeve 71, two transmission rods 72, toothed plates 73 connected to the transmission rods 72, gears 74 meshing with the toothed plates 73, a positioning ring 75, and a third elastic element 76. The two transmission rods 72 extend from both ends of the transverse sleeve 71. The inner ends of the two transmission rods 72 slide and seal against the inner wall of the transverse sleeve 71, forming a driving cavity between the two inner ends. A guide pipe 522 communicates with the middle of the driving cavity. After the working fluid enters the driving cavity, it acts simultaneously on the inner ends of the two transmission rods 72, causing the two transmission rods 72 to move in opposite directions. The toothed plates 73 move with the transmission rods 72 and drive the gears 74 to rotate. The gears 74 drive the rotating disk 631 to rotate via the rotating shaft 633. The positioning ring 75 provides a fixed position for the third elastic element 76. When the transmission rods 72 move outward, the third elastic element 76 undergoes elastic deformation. After the hydraulic pressure in the driving cavity decreases, the third elastic element 76 drives the transmission rods 72 to return to the middle of the transverse sleeve 71.

[0041] The vertical compression stroke in the second stage does not need to be very long because the liquid discharged simultaneously from multiple compression sleeves 41 enters the transmission assembly 7 together, and the effective liquid-receiving area at the inner ends of the two transmission rods 72 can be set to be less than the sum of the effective liquid discharge areas of multiple sealing heads 421. Under conditions of minimal liquid leakage, liquid compression, and pipeline elastic deformation, the liquid discharge volume in the second stage and the lateral displacement of the transmission rods 72 can approximately satisfy the following equation: (1) In equation (1), This indicates that the pressure seat 3 enters the transmission assembly 7 with a new volume of working fluid as it continues to descend in the second stage; This indicates the number of floating compression components 4 participating in the second stage of drainage; Indicates the first The effective drainage area of ​​the sealing head 421 is determined by the effective cross-section of the sealing head 421 in contact with the liquid cavity. Indicates the first The incremental retraction stroke of each main pressure rod 42 in the second stage can be determined by the displacement of the lifting drive 22 and the actual pressure state of each main pressure rod 42. This indicates the effective liquid-receiving area at the inner end of a single transmission rod 72; and These represent the distances that the two transmission rods 72 move outward from the transverse sleeve 71. When the structures and resistances of the two transmission branches are basically symmetrical, and Approximately. Equation (1) is used to explain the conversion relationship between the discharge volume in multiple liquid chambers and two drive branches, and is not used to limit the specific size of each component. When there is a lot of residual gas in the system, obvious sealing leakage, or large elastic deformation of the pipe, the actual lateral displacement will be less than the theoretical value obtained according to this relationship. In this case, venting, sealing and structural stiffness checks should be performed first.

[0042] As shown in equation (1), under the premise of ensuring that the transmission rod 72 can obtain sufficient hydraulic pressure, reducing the effective liquid receiving area at the inner end of the transmission rod 72 can convert the smaller second-stage retraction stroke of multiple main pressure rods 42 into a larger lateral movement distance of the toothed plate 73. The simultaneous discharge of liquid from multiple sealing heads 421 also increases the flow rate entering the drive chamber per unit time, making the lateral movement speed of the toothed plate 73 higher than the axial movement speed of a single main pressure rod 42. After the toothed plate 73 further meshes with the gear 74 with a smaller pitch circle radius, it can generate a larger rotation angle and a higher rotation speed of the rotating disk 631 within the limited toothed plate stroke. As a result, multiple magnetic suction elements 632 pass through the magnetic attraction position of the metal ball 64 in sequence during the shorter duration of the second stage, thereby completing multiple lifting and releasing operations.

[0043] The effective hydraulic contact area of ​​the transmission rod 72 should not be infinitely reduced in pursuit of increased displacement. During design, the thrust generated by the hydraulic pressure within the drive chamber acting on the transmission rod 72 should be greater than the elastic resistance of the third elastic element 76, the sealing friction of the transmission rod 72, the transmission resistance between the toothed plate 73 and the gear 74, and the load when the rotating disk 631 drives the magnetic suction element 632 to rotate. The diameter of the transmission rod 72 can be determined first based on the pressure that the lifting drive component 22 can provide in the second stage and the discharge volume of the multiple main pressure rods 42. Then, the rotation angle of the rotating disk 631 can be adjusted by the pitch circle diameter of the gear 74 and the number of magnetic suction elements 632. The rotation speed should not be too high. Sufficient non-magnetic space should be maintained within one revolution of the rotating disk 631 to allow the metal ball 64 to fall and impact between adjacent magnetic suction elements 632. If the next magnetic suction element 632 enters the magnetic suction position too early, the metal ball 64 may be attracted again before impacting the auxiliary push rod 61, thus reducing the effective number of impacts.

[0044] By adopting the above-mentioned motion amplification relationship, it is possible to avoid setting the vertical stroke of the second-stage pressing seat too long in order to obtain multiple impacts. If the vertical stroke of the second stage is too long, the auxiliary push rod 61 will generate too much retraction relative to the auxiliary sleeve 621, and the effective falling space of the metal ball 64 will be continuously compressed. The auxiliary sleeve 621 will also need to be set with a larger axial dimension, which may easily lead to an increase in the overall height of the equipment and a mismatch between the magnetic attraction area and the actual movement position of the metal ball 64. This application, through the combination of the total drainage area of ​​multiple liquid chambers and the smaller driving liquid receiving area, obtains a larger stroke of the toothed plate 73 and the rotation angle of the rotating disk 631 within a smaller pressing increment, so that the auxiliary processing can be concentrated in the short period of time before the product has completed the final static holding pressure.

[0045] The impact intensity of the metal ball 64 can naturally change with the pressing depth during the second stage. At the beginning of the second stage, the auxiliary push rod 61 just contacts the periphery of the smart screen assembly 100, and its impact-bearing end inside the auxiliary sleeve 621 is relatively low. After the metal ball 64 is lifted and released by the magnetic attractor 632, it has a large effective falling distance, and the pressure pulsation generated by the initial impact is relatively strong. As the pressing seat 3 continues to descend, the auxiliary push rod 61 gradually retracts into the auxiliary sleeve 621, the impact-bearing end of the auxiliary push rod 61 rises, while the main lifting and releasing area corresponding to the magnetic attractor 632 remains basically unchanged relative to the auxiliary sleeve 621. The effective falling distance of the metal ball 64 decreases accordingly, and the subsequent impact gradually weakens.

[0046] The gradual change in impact strength corresponds to the bonding process of the adhesive layer. In the initial stage of the second phase, the adhesive layer between the display assembly and the frame has not yet fully spread. The strong initial pressure pulsation can cause short-term local flow in the adhesive layer, causing larger trapped air bubbles to detach from their original positions and migrate towards the not-yet-completely-sealed edges. As the adhesive layer gradually thins and forms a larger contact area, the subsequent weaker pressure pulsation continues to promote small-scale gas migration, while reducing the possibility of lateral movement of the already basically positioned display assembly, excessive extrusion of adhesive material, or excessive instantaneous load on the edges. The flexible contact head at the lower end of the second elastic element 622 and the auxiliary push rod 61 further reduces the impact peak value. The metal ball 64 does not directly contact the smart screen assembly 100, and the auxiliary processing component 6 forms a small axial pressure fluctuation superimposed on the continuous bonding load.

[0047] The initial falling distance and mass of the metal ball 64, the magnetic force of the magnetic 632, the stiffness of the second elastic element 622, and the maximum retraction of the auxiliary push rod 61 should be determined in a coordinated manner. At the end of the second stage, a minimum distance should still be maintained between the impact end of the auxiliary push rod 61 and the release position of the metal ball 64 to ensure an effective fall. If the impact is too strong, the mass of the metal ball 64 can be reduced, the initial falling distance can be reduced, the magnetic force of the magnetic 632 can be reduced, the buffering capacity of the second elastic element 622 can be increased, or the thickness of the flexible contact head can be increased, provided that the metal ball 64 can complete each fall. All the above adjustments should be based on the premise that no visible displacement or local damage occurs to the smart screen assembly 100.

[0048] When the equipment is in operation, the pressing seat 3 is first positioned in the raised reset position. The first elastic element 43 resets each main pressing rod 42, the second elastic element 622 positions the auxiliary push rod 61 in the initial extended position, and the third elastic element 76 brings the two transmission rods 72 close to the middle of the transverse sleeve 71. The operator checks whether the initial liquid level in the liquid level observation window 53 is at the set position and confirms that there are no visible leaks at each sealing position. Then, the smart screen assembly 100 to be pressed is placed in the rectangular bearing area enclosed by the positioning seat 13, so that the frame is supported by the positioning seat 13, the display assembly is pre-positioned in the frame, and the adhesive layer to be bonded is located in the corresponding pressing area.

[0049] When the pressing seat 3 begins to descend, it can initially approach the product at a relatively fast speed, switching to a low speed before the pressing block 45 approaches the smart screen assembly 100. In the flat pressing mode, each adjusting pressure rod 44 remains in a free state; in the preset contour mode, each adjusting pressure rod 44 remains in the locked state after standard part calibration. After multiple pressure blocks 45 complete initial contact and establish axial force transmission relationship, the pressing seat 3 continues to descend, each main pressure rod 42 moves relative to the pressing sleeve 41, the first elastic element 43 undergoes elastic deformation, and each sealing head 421 discharges working fluid into the fluid collection chamber 5.

[0050] After the pressing seat 3 reaches the predetermined first-stage position, it can pause briefly to reduce liquid surface sloshing, and then observe the liquid level observation window 53. When the liquid level is within the allowable range corresponding to the liquid level indicator 51, the total effective displacement of multiple pressing positions is considered to meet the requirements for entering the second stage; when the liquid level is significantly lower or higher than the allowable range, the pressing seat 3 is stopped from descending further and is raised to verify the assembly position, local contour, adhesive layer, foreign objects, and initial liquid level of the smart screen assembly 100. If the liquid level is abnormal, the pressing stroke is not forcibly increased to reach the target liquid level to avoid applying excessive load to products with abnormal positions or foreign objects.

[0051] After the liquid level verification is passed, the pressing seat 3 continues to perform the second stage of short-stroke compression at a low speed. The liquid level in the liquid collection chamber 5 continues to rise from the liquid level indicator 51 to the liquid inlet of the high-level guide section 52, and the newly added working fluid enters the drive chamber of the transverse sleeve 71 through the top flow channel 521 and the guide pipe 522. Under the action of hydraulic pressure, the two transmission rods 72 move outward, the toothed plate 73 drives the gear 74 and the rotating disk 631 to rotate, and multiple magnetic suction elements 632 sequentially lift, release, fall and impact the auxiliary push rod 61. Under the action of the second elastic element 622, the auxiliary push rod 61 continues to adhere to the periphery of the product, converting multiple micro-impacts into pressure fluctuations superimposed on the pressing load, so as to promote the spread of the adhesive layer and the outward migration of trapped gas.

[0052] After the pressing seat 3 reaches the final pressing position, it stops descending and no more liquid is discharged. The transmission rod 72 stops moving outward, the rotating disk 631 stops rotating, the metal ball 64 stops its cyclical impact, and the multiple pressing blocks 45 and the auxiliary push rod 61 maintain continuous pressure on the smart screen assembly 100. The equipment enters the static pressure holding stage. The static pressure holding time is determined based on the adhesive layer type, product size, ambient temperature, and process verification results. During the static pressure holding stage, no dynamic impacts continue to occur, allowing the already spread adhesive layer to complete bonding, shaping, or curing under a relatively stable load, reducing the possibility of product position drift caused by continuous vibration.

[0053] After the set pressure holding time is reached, the lifting drive component 22 drives the pressing seat 3 to rise. The external load on the main pressure rod 42 is released, and the first elastic element 43 drives the main pressure rod 42 to reset. The working fluid in the fluid collection chamber 5, the high-level guide section 52, and the driving chamber returns to their respective fluid chambers along the original path. After the hydraulic pressure in the driving chamber decreases, the third elastic element 76 drives the transmission rod 72 and the toothed plate 73 to reset. After the pressing load on the auxiliary push rod 61 is released, the second elastic element 622 drives the auxiliary push rod 61 to reset. During the resetting process of the toothed plate 73, the rotating disk 631 may rotate in the opposite direction, but at this time the pressing seat 3 has already risen, and the auxiliary push rod 61 gradually disengages from the smart screen assembly 100. The resetting motion will not transmit effective pressing impact to the product. After the pressing seat 3 returns to the part removal position, the smart screen assembly 100 that has been pressed is removed and the next part to be pressed is installed.

[0054] In another embodiment, this device is used for hot melt adhesive films, heat-activated tapes, PUR reactive hot melt adhesives, or other adhesives that need to be pressed under a heated state. Heating can be provided by existing constant temperature pressing platforms, the matching heating structure of positioning seat 13, or the constant temperature station where pressing seat 3 is located. The floating conformal, liquid level verification, and auxiliary micro-impact structures of this application do not depend on a specific heating source. The pressing block 45 can be made of aluminum alloy or copper alloy substrate and equipped with a high-temperature resistant silicone contact pad to balance heat transfer and surface buffering; to reduce adhesive adhesion, a polyimide film or a polytetrafluoroethylene thin layer can be provided on the contact surface. The seal adjacent to the high-temperature area can be made of fluororubber, the working fluid can be a low-viscosity silicone oil with stable viscosity-temperature performance or a hydraulic oil suitable for the corresponding temperature, the liquid level observation window 53 can be made of borosilicate glass, and the magnetic suction component 632 can be made of a high-temperature resistant neodymium iron boron magnet or a samarium cobalt magnet.

[0055] During hot pressing or heat sealing, the thermal expansion of the working fluid, the elastic change of the sealing element, and the thermal deformation of the pressing seat 3 may all alter the initial liquid level. Therefore, the equipment should be calibrated using standard parts after reaching a stable process temperature, with the initial liquid level at the stable temperature and the first-stage target liquid level used as the judgment benchmark. If the temperature difference between the heating zone and the liquid collection chamber 5 is large, liquid level drift can be checked after trial operation and compensated by adjusting the initial injection volume or resetting the liquid level indicator 51. After hot pressing, the specified pressure holding or cooling time should be completed before the pressing load is released to avoid removing the part before the adhesive material has formed a stable bond. Through the above materials and calibration methods, this equipment can be applied to room temperature pressure-sensitive bonding and heat sealing processes requiring temperature rise, without changing the working sequence of the high-level guide section 52 being verified before being driven.

[0056] In another embodiment, to facilitate the determination of the dimensional relationships in the second stage, non-limiting prototype parameters can be used for debugging. For example, sixteen sealing heads 421 with effective diameters of approximately ten millimeters are set along the periphery of the smart screen assembly 100. Each main pressure rod 42 continues to retract by an average of approximately 0.6 millimeters in the second stage, and the effective diameters of the inner ends of the two transmission rods 72 are approximately five millimeters respectively. Under good sealing and sufficient venting conditions, the total drainage of multiple liquid chambers can enable the two transmission rods 72 to obtain a theoretical lateral movement distance of approximately nineteen millimeters respectively. When the gear 74 adopts a smaller pitch circle diameter and multiple magnetic suction elements 632 are set around the rotating disk 631, multiple magnetic suction processes can be formed within this short stroke. The above data is only used to illustrate the feasible implementation of converting a small vertical stroke into a larger lateral stroke. The actual dimensions should be determined through prototype testing based on the number of pressing points, the pressure that the lifting drive 22 can provide, the stiffness of the third elastic element 76, sealing friction, and the required number of impacts.

[0057] After initial use, product specification change, working fluid change, or disassembly / reassembly of sealing components, liquid injection and venting, initial liquid level check, and standard component calibration should be performed again. If the initial liquid level in the liquid level observation window 53 continues to drop, check for leaks in the sealing head 421, the sealing section of the transmission rod 72, the liquid connection port 54, the sealing point of the observation window, and the liquid injection port. If the liquid level is normal in the first stage but the stroke of the transmission rod 72 is significantly insufficient in the second stage, check for blockage in the high-level guide section 52, residual gas in the drive chamber, excessively high working fluid viscosity, excessively high stiffness of the third elastic element 76, and jamming of the transmission rod 72. If the metal ball 64 cannot fall stably, check the non-magnetic gap between the magnetic suction elements 632, the material of the auxiliary sleeve 621, the friction between the metal ball 64 and the sleeve, and the rotation speed of the rotating disk 631. Through the above checks, abnormal liquid level, insufficient transmission, and impact failure can be located to the corresponding structures, avoiding the situation where equipment failure is masked simply by increasing the pressure load.

[0058] In the above embodiments, the dimensions and materials of each structure can be adjusted according to the specifications and adhesive process of the smart screen assembly 100. However, it should be ensured that the multiple adjustment pressure rods 44 can adapt to or reproduce the periphery contour of the product before the main pressure load is established. The total amount of liquid discharged by the multiple main pressure rods 42 can form a verifiable liquid level in the first stage. The liquid inlet of the high-level guide part 52 is higher than the liquid level marking part 51. The additional liquid discharge in the second stage can drive the transmission rod 72 and the rotating disk 631 to move. The time for the metal ball 64 to complete the release and fall is retained between adjacent magnetic suction parts 632. The auxiliary push rod 61 maintains contact with the product in the second stage and stops dynamic impact in the final static pressure holding stage.
