Description

Technical Field

[0001] This invention relates to the field of LED light strip technology, and in particular to an LED light strip bonding device for embedded LED automotive glass processing. Background Technology

[0002] In the production process of embedded LED windshield / side window glass for new energy vehicles, LED light strips need to be attached to the PVB film between two layers of glass according to a standard triangular outline. Subsequently, the film is encapsulated and formed by lamination, vacuuming, and hot pressing.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems in the bonding of LED light strips during the processing of embedded LED automotive glass: At present, the bonding of LED light strips for automotive glass mostly relies on manual operation. Manual positioning and bonding has poor accuracy and it is difficult to ensure that the triangular bonding shape is regular and uniform. At the same time, manual bonding cannot adapt to the curvature of the automotive glass surface, which easily leads to quality problems such as hollow light strips, wrinkles, and poor bonding. In addition, the manual step-by-step positioning, pressing, and shaping process is cumbersome and has low processing efficiency, which cannot meet the needs of mass automated production.

The equipment adopts a double-layer closed-loop triangular guide rail and a standardized △-shaped walking path throughout the process, which completely replaces manual shaping. The workpiece light strip outline dimensions are uniform. Relying on the closed fluid linkage pressure holding bladder for flexible pressure application, combined with the lifting buffer spring and roller floating structure, it can adapt to the curved surface of automotive glass. The pressure is uniform throughout the bonding process, eliminating defects such as hollowness, wrinkles, and loose adhesion. The flexible extrusion will not scratch the glass or damage the LED light strip, and the appearance of the finished product is significantly improved.

The mechanical lifting displacement synchronously controls the time-sharing action of the clamping bag and the pressing bag: pressing down automatically loosens the clamp to facilitate material feeding and bonding, and lifting automatically clamps and fixes the end of the light strip, eliminating the need for manual repeated positioning and pulling of the light strip. The equipment integrates an automatic unwinding and walking mechanism, and the entire process of triangular bonding, clamping and pressing is automated. Only manual loading and unloading of glass workpieces is required, which greatly reduces the intensity of manual operation, effectively shortens the processing time of a single piece, and reduces labor and material costs.

Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figures 1 to 8This is the first embodiment of the present invention. This embodiment provides an LED strip bonding device for embedded LED automotive glass processing. It is mainly used for automated bonding processing of embedded LED strips with PVB film on automotive glass. It is especially suitable for the standardized bonding process of LED strips in a △ shape, effectively solving many industry defects of traditional manual bonding process. The LED strip bonding device for embedded LED automotive glass processing includes a strip bonding mechanism 1.

[0035] Specifically, the LED strip bonding mechanism 1 is fixedly installed and is used to bond the LED strip in a △ shape to the automotive glass with PVB film. It eliminates the need for manual bonding of the LED strip. Subsequently, another layer of automotive glass is covered, and vacuuming and heat pressing are performed in sequence with the help of other devices to embed the LED light between the two pieces of glass. The LED strip bonding mechanism 1 includes: a frame 11, which is fixedly installed. The frame 11 is the mounting base of the whole machine and provides a fixed mounting reference and working space for each component.

[0036] Specifically, the lifting component 12 is installed on the frame 11. The lifting component 12 is vertically mounted above the frame 11 and serves as the core actuator for the vertical lifting and flexible pressure adjustment of the whole machine. It can achieve fitting adjustment and flexible buffer pressing to avoid rigid extrusion damage to the workpiece.

[0037] Specifically, the LED strip bonding and walking trajectory assembly 13 is installed on the lifting component 12 to achieve precise two-dimensional planar movement. This guides and drives bonding execution components such as rollers 14 and pressure bladders 15 to move smoothly and continuously along the surface of the automotive glass according to a preset △-shaped path, ensuring that the LED strip can be accurately and firmly bonded to the PVB film. The LED strip bonding and walking trajectory assembly 13 adopts a double-layer triangular closed-loop guide rail structure, which can achieve a stable triangular closed-loop walking trajectory, accurately matching the bonding requirements of the △-shaped LED strip on the automotive glass. The LED strip bonding and walking trajectory assembly 13 integrates a driving walking component 136, which provides power for trajectory walking and automatic feeding, and can carry the rolled LED strips to automatically walk and feed along the preset triangular trajectory.

[0038] Specifically, there are two rollers 14, which are installed on the drive end of the LED strip bonding and walking trajectory assembly 13. They are used to roll smoothly along a preset path under the drive of the assembly, apply pressure to the LED strip, and ensure that the LED strip and the PVB film are tightly bonded. The roller 14 has an I-shaped cross section. The pressure-holding pouch 15 is embedded in the roller 14 and is connected to the roller 14. It is used to apply pressure to the LED strip being bonded when the roller 14 moves along the path. The clamping pouch 16 is embedded in the inner wall of the roller 14 and is connected to the roller 14. It is used to clamp the LED strip after a single bonding is completed and during the rising phase. After the single bonding is cut off, it keeps one end of the LED strip clamped, so that it can be unlocked when the next downward movement bonding is performed. The outer surface of the clamping pouch 16 is provided with protrusions that are integrally distributed in a circumferential array.

[0039] The bottom of the drive walking component 136 is equipped with a roller 14 via a mounting component 137. The roller 14 is the core fitting and execution component, with an internal dual-channel independent fluid pipeline, which is equipped with a pressure bladder 15 and a clamping bladder 16 respectively, which can simultaneously realize the clamping and limiting of the light strip and the flexible pressing and fitting of the curved surface.

[0040] Specifically, the pressure component 17 is installed on the lifting component 12 and the LED strip bonding and travel trajectory assembly 13, and cooperates with the pressure bladder 15 and the clamping bladder 16. When the lifting component 12 drives the LED strip bonding and travel trajectory assembly 13 and the roller 14 to move down, and the roller 14 contacts the PVB film on the automotive glass, the lifting component 12 continues to move, and the roller 14 stops moving down. At this time, the pressure component 17 is triggered to work, causing the clamping bladder 16 to contract and release the fixation on the end of the LED strip. At the same time, the pressure bladder 15 expands to apply pressure to the LED strip, ensuring that the LED strip is tightly abutted against the PVB film on the automotive glass. Then the roller 14 moves, driving the rolled LED strip to be passively unloaded, and finally the LED strip is bonded to the automotive glass with the PVB film in a △ shape.

[0041] The machine integrates pressure component 17 and adopts a mechanical lifting linkage fluid pressurization structure. It does not require external pneumatic or hydraulic power equipment. It relies on the vertical displacement of lifting component 12 to automatically squeeze the internal incompressible fluid, realizing the fully enclosed system's adaptive pressurization, pressure holding, and pressure release. It controls the expansion and contraction deformation of the two sets of bladders and dynamically adapts to the glass surface error. This device achieves fully automatic positioning, feeding, trajectory walking, and flexible bonding through a pure mechanical linkage + fluid adaptive pressure system, solving the technical problems of low accuracy, poor quality, low efficiency, and poor adaptability of traditional manual bonding.

[0042] Example 2, refer to Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0043] Specifically, the lifting component 12 is the core execution structure for overall height adjustment, flexible pressing, and fluid pressure linkage. It is mainly used to drive the entire LED strip bonding and walking trajectory assembly 13 to vertically lift and lower, realizing LED strip bonding pressure adjustment and flexible bonding operations. The lifting component 12 includes: a hydraulic cylinder 121, which is set above the LED strip bonding and walking trajectory assembly 13 and serves as the active lifting power source; a lifting plate 122, which is fixed to the lower end of the hydraulic cylinder 121 and transmits lifting power; and three vertical rods 123, which slide through the lifting plate 122 in a circular array. The vertical rods 123 adopt a three-point circular layout to ensure that the lifting plate 122 is evenly stressed, prevents deflection, and prevents jamming.

[0044] The stop block 124 is fixed to the upper end of the vertical rod 123 by bolts and cooperates with the top of the lifting plate 122. The stop block 124 limits the maximum downward stroke of the vertical rod 123 on the lifting plate 122 to prevent the structure from falling off. At the same time, when the lifting plate 122 moves upward and abuts against the stop block 124, the stop block 124 and the vertical rod 123 move upward synchronously during the upward process of the lifting plate 122, thereby driving the LED strip to move upward along the travel trajectory assembly 13. The spring 125 is sleeved on the surface of the vertical rod 123, and its two ends abut against the surface of the LED strip moving trajectory assembly 13 and the bottom of the lifting plate 122, respectively. The spring 125 normally provides elastic support force, so that the lifting plate 122 and the hydraulic cylinder 121 have flexible buffer stroke, realizing the composite effect of rigid drive + flexible pressing, avoiding rigid extrusion damage to the LED strip and the car glass.

[0045] Descent bonding condition: The hydraulic cylinder 121 extends to push the lifting plate 122 downward, causing the entire LED strip bonding trajectory assembly 13 to move downward. When the roller 14 comes into contact with the automotive glass with PVB film, the lifting plate 122 continues to move downward to compress the spring 125, transmitting pressure to the LED strip bonding trajectory assembly 13 at the lower end of the vertical rod 123, making the entire bonding mechanism close to the automotive glass surface, achieving LED strip tight bonding; Flexible adaptive condition: At the moment of bonding contact, there is a slight curvature error on the glass surface. The spring 125 can be compressed and buffered, automatically adapting to the glass curvature, avoiding hard pressure that could cause glass breakage or LED strip deformation; Upward reset condition: The hydraulic cylinder 121 retracts to drive the lifting plate 122 upward, the abutment block 124 lifts the vertical rod 123, and at the same time the spring 125 rebounds to assist in reset, driving the entire trajectory assembly to rise smoothly, detach from the workpiece, and complete a single bonding reset.

[0046] Specifically, the lifting component 12 includes: two frames 126, symmetrically fixed to the top of the frame 11, serving as vertical support bases; two guide rods 127, respectively fixed to the two frames 126, arranged in parallel and symmetrically to form a stable double-column guide; a support plate 128, fixed to the upper end of the guide rods 127, with a hydraulic cylinder 121 passing through and fixed to the support plate 128, and an opening in the middle of the support plate 128 to allow the hydraulic cylinder 121 to be installed through and fixed, ensuring that the hydraulic cylinder 121 is installed vertically, coaxially, and without sway; and two sliding sleeves 129, respectively slidingly fitted onto the surfaces of the two guide rods 127, with one end of the sliding sleeve 129 fixed to the light strip bonding and walking trajectory assembly 13, allowing the light strip bonding and walking trajectory assembly 13 to slide vertically along the guide rods 127, limiting horizontal swaying and torsional offset, and improving the stability and bonding accuracy of the equipment's bonding operation.

[0047] Specifically, the LED strip conforming walking trajectory component 13 is a key structure for achieving automatic conforming of the triangular trajectory, surface self-adaptation, and synchronous control of fluid pressure. The LED strip conforming walking trajectory component 13 includes: a triangular plate 131, fixed to the lower end of the vertical rod 123, serving as the load-bearing base of the overall walking mechanism; a first triangular guide rail 132, fixedly sleeved on the surface of the triangular plate 131; and a second triangular guide rail 133, located on the outer ring of the first triangular guide rail 132. Both the first triangular guide rail 132 and the second triangular guide rail 133 have rounded transitions at their corners to ensure smooth sliding. The smooth change of direction when wheel 1361 moves to a corner is achieved through the cutting of the sides of the LED light strips used in this device. This special design aims to solve the stress concentration problem faced by the light strip when it is in rounded corners or complex bending shapes. The presence of the cutting effectively releases the extrusion and tensile stress on the side material of the light strip during bending, thereby ensuring that the internal circuit and packaging structure of the light strip will not break or be damaged due to excessive local stress when it is fitted to rounded corners or bent at large angles, thus ensuring the reliability of the light strip in fitting and the structural integrity of long-term use.

[0048] Triangular guide rail 132 and triangular guide rail 2 133 form an inner and outer double-layer triangular closed-loop guide rail structure, providing track constraints for triangular trajectory movement; ring plate 134 is fixedly sleeved on the surface of triangular guide rail 2 133, and one end of sliding sleeve 129 is fixed to the surface of ring plate 134; there are three U-shaped rods 135, with both ends fixed between the top of triangular guide rail 132 and the top of ring plate 134 respectively. The three U-shaped rods 135 connect and fix triangular guide rail 132, triangular guide rail 2 133 and ring plate 134 into an integrated frame structure, which has strong overall rigidity and is not easily deformed.

[0049] The drive walking component 136 is mounted on the triangular plate 131 and provides power for cyclical movement along the triangular guide rail. The mounting component 137 is mounted on the drive walking component 136, and the roller 14 is mounted on the mounting component 137. The mounting component 137 and the roller 14 achieve rolling contact movement. The pressure component 17 is mounted on the triangular plate 131, the lifting plate 122, the drive walking component 136, and the mounting component 137. The pressure component 17 is connected to the roller 14 through the drive walking component 136 and the mounting component 137, thereby acting on the pressure holding bladder 15 and the clamping bladder 16.

[0050] The pressure component 17 is integrated on the triangular plate 131, the lifting plate 122, the driving and walking component 136, and the mounting component 137. Relying on the pressure transmission of incompressible fluid, it synchronously controls the expansion and contraction deformation of the pressure holding bladder 15 and clamping bladder 16 matched with the roller 14, so as to realize the clamping and unlocking of the light strip, adaptive pressing and decompression, and curved surface fitting compensation. The fluid pipeline of the pressure component 17 is unobstructed and ensures that the bladder expands and contracts synchronously, and the fitting pressure is uniform and stable.

[0051] After the lifting component 12 descends to its position, the fluid pressure changes due to the stroke change of the pressure component 17. The pressure is then synchronously transmitted to the holding bladder 15 and the clamping bladder 16 through the internal flow channels and pipelines. This causes the clamping bladder 16 to contract and release the clamping of the light strip, while the holding bladder 15 expands to apply pressure to the light strip, bonding one end of the light strip to the PVB film on the automotive glass. The driving component 136 moves along the inner and outer double-layer triangular guide rails in a triangular closed-loop trajectory, driving the roller 14 and the light strip to complete a △-shaped bonding path along the surface of the automotive glass. During the movement, the spring 125 and the holding bladder 15 adaptively and dynamically compensate for the curvature error of the glass surface, ensuring that the light strip is tightly bonded and wrinkle-free throughout the entire process.

[0052] Specifically, the drive walking component 136 enables precise closed-loop movement along the triangular guide rails and automatic feeding of the light strip. The drive walking component 136 includes: two pulleys 1361, which slide within the first triangular guide rail 132 and the second triangular guide rail 133 respectively. The two pulleys 1361 are embedded in the first triangular guide rail 132 and the second triangular guide rail 133 respectively, achieving double-track limiting, anti-derailment, and anti-deviation, allowing the light strip roll to rotate and unwind freely; a connecting plate 1362, fixed to the lower end of the pulleys 1361; a tube 1363, fixed through the connecting plate 1362 and passing through the gap between the first triangular guide rail 132 and the second triangular guide rail 133, which can slide freely without interfering with the track movement; and a mounting component 137 installed at the lower end of the tube 1363.

[0053] Two unwinding frames 1364 are symmetrically distributed and fixed to the upper end of the tube 1363 to hold the rolled LED light strip material with rollers. The LED light strip passes through the tube 1363 for feeding. There is a certain damping between the rollers and the unwinding frames 1364. The light strip roll will not easily rotate under non-pull action, and the unwinding resistance of the light strip is uniform, avoiding the light strip from being pulled and deformed or unevenly tensioned. The rotating column 1365 rotates on the triangular plate 131 and is rotatably connected to the triangular plate 131 through a bearing. The drive frame 1366 is fixedly sleeved on the surface of the rotating column 1365 at one end. The tube 1363 slides in the inner cavity of the drive frame 1366. The drive frame 1366 can drive the tube 1363 to move along the triangular trajectory, while retaining the tube 1363's adaptive sliding margin. The geared motor 1367 is fixed to the top of the triangular plate 131, and the upper end of the rotating column 1365 is fixed to the output shaft of the geared motor 1367.

[0054] When the geared motor 1367 starts, it drives the rotating column 1365 and the drive frame 1366 to rotate. The drive frame 1366 drives the tube body 1363, the connecting plate 1362 and the pulley 1361 to move along the double-layer triangular guide rail in a closed-loop triangular trajectory. The rolled light strip is placed on the unwinding frame 1364 and is automatically unwound as the mechanism moves. The light strip is conveyed down along the tube body 1363 to the contact position of the roller 14 on one side. The double pulley and double rail limit ensure that the travel trajectory is accurate, does not derail or deviate, and stably completes the △-shaped path contact operation.

[0055] Example 3, referring to Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the mounting component 137 includes: a mounting plate 1371, fixedly sleeved on the lower end of the tube body 1363; four U-shaped plates 1372, symmetrically distributed and fixed to the inner wall of the mounting plate 1371; four sliders 1373, each sliding on one of the four U-shaped plates 1372; two short tubes 1374, each rotating on one side of the corresponding two sliders 1373, with one end fixed to one side of the roller 14; and two short tubes 1375, each rotating on the other side of the corresponding two sliders 1373, with one end fixed to the other side of the roller 14. On one side, short pipe 1374 and short pipe 2 1375 are rotatably connected to slider 1373 via bearings. With the cooperation of U-shaped plate 1372 and slider 1373, roller 14 can rotate freely and has a slight left-right floating capability. Short pipe 1374 and short pipe 2 1375 can rotate synchronously with roller 14 to ensure that the pipeline does not twist or interfere under rotation conditions. There are four springs 1376, with their two ends fixed between the surface of slider 1373 and the surface of mounting plate 1371, respectively. Springs 1376 provide elastic preload, enabling roller 14 to have a slight left-right floating compensation capability.

[0057] Specifically, a circular groove 141 is provided on one side of the roller 14, and the circular groove 141 is connected to one end of a short tube 1374 on one side. A channel 142 distributed in a circular array is provided inside the roller 14, and the two ends of the channel 142 are connected to the circular groove 141 and the pressure bag 15 respectively. A groove 143, an annular groove 144, and a connecting hole 145 and a channel 146 distributed in a circular array are provided inside the roller 14. The groove 143 is connected to one end of the short tube 1375 on one side. The two ends of the channel 146 are connected to the groove 143, the annular groove 144 and the clamping bag 16 respectively. The two ends of the connecting hole 145 are connected to the groove 143 and the annular groove 144 respectively.

[0058] Roller 14 has a circular groove 141 on one side that connects to short tube 1374. Multiple channels 142 are arranged in a circular array inside roller 14. Channel 142 connects the circular groove 141 to the outer pressure bladder 15, forming a first independent fluid pressure path for pressing and fitting the light strip on the outside. Inside roller 14, there is another groove 143, annular groove 144, connecting hole 145 and channel 146. Groove 143 connects to short tube 1375. Groove 143 connects to annular groove 144 through connecting hole 145. Annular groove 144 then connects to inner clamping bladder 16 through circular array channel 146, forming a second independent fluid path for clamping and positioning the light strip on the side and unlocking the clamp. The two fluid paths are completely isolated and independently controlled, and can work synchronously to achieve clamping and limiting of the light strip and pressing and fitting of the curved surface, respectively.

[0059] Specifically, the pressure component 17 converts mechanical lifting motion into fluid pressure. The pressure component 17 includes: a cylinder 171 fixed to the top of the triangular plate 131; a piston 172 sliding inside the cylinder 171; a piston rod 173 sliding through the upper end of the cylinder 171, with its upper end fixed to the bottom of the lifting plate 122 and its lower end fixed to the top of the piston 172; and a sealing treatment between the cylinder 171 and the piston 172 and the piston rod 173; and an annular shell 174 fixed to the bottom of the triangular plate 131 and sealed through a sealing ring. A sealing bearing is fitted onto the surface of the rotating column 1365; a second annular shell 175 is fixed to the bottom of the first annular shell 174 and fitted onto the surface of the rotating column 1365 via a sealing bearing; a first flow channel 176 and a second flow channel 177 are respectively opened inside the rotating column 1365, one end of the first flow channel 176 is connected to the second annular shell 175, and one end of the second flow channel 177 is connected to the first annular shell 174; a first tee pipe 178 is fixed to one side of the mounting plate 1371 via a support rod; a second tee pipe 179 is fixed to the other side of the mounting plate 1371 via a support rod.

[0060] The downward movement of the lifting plate 122 can push the piston 172 to compress the fluid at the lower end of the cylinder 171, thereby expanding and automatically pressurizing the pressure holding bladder 15. At the same time, the piston 172 draws in the fluid at the upper end of the cylinder 171, creating a negative pressure environment, which draws in the clamping bladder 16 and causes it to contract, releasing the clamping limit on the light strip. Under the action of the roller 14 and the downward pressure of the pressure holding bladder 15, the light strip is smoothly adhered to the PVB film on the automotive glass. Flow channel one 176 and flow channel two 177 achieve continuous fluid communication and no leakage during rotation. T-pipe one 178 and t-pipe two 179 are used to divert and connect the rear bend pipe and the roller 14 pipeline, achieving precise distribution and delivery of pressurized fluid.

[0061] Specifically, the pressure component 17 also includes: two bends 1710, one end of which slides inside one end of a tee pipe 178, and the other end rotates inside a short pipe 1374 via a sealed bearing, with a seal between bends 1710 and tee pipe 178; and two bends 1711, one end of which slides inside one end of a tee pipe 279, and the other end rotates inside a short pipe 2275 via a sealed bearing, with a seal between bends 1711 and tee pipe 2279, to achieve dynamic sealing and continuous connection of the pipeline under the rotating condition of the roller 14, solving the problems of entanglement and leakage in rotating pipelines.

[0062] Connecting pipe 1712, with its two ends connected between the lower end of cylinder 171 and annular shell 175; connecting pipe 1713, with its two ends connected between the upper end of cylinder 171 and annular shell 174; flexible hose 1714, with its two ends connected between one end of flow channel 176 and the upper end of tee pipe 178; flexible hose 1715, with its two ends connected between one end of flow channel 177 and the upper end of tee pipe 179.

[0063] The chamber formed between piston 172 and cylinder 171, connecting pipe 1712, connecting pipe 2 1713, flow channel 176, flow channel 2 177, hose 1714, hose 2 1715, tee pipe 178, tee pipe 2 179, bend pipe 1710, bend pipe 2 1711, short pipe 1374, short pipe 2 1375, roller 14, pressure bladder 15 and clamping bladder 16 are all filled with incompressible fluid, which can be gas or liquid, forming a fully enclosed adaptive fluid pressure system without external pump pressure.

[0064] The cylinder 171 is also equipped with a fluid replenishment device, which is not shown in the attached drawings. The main function of the replenishment device is to replenish the cylinder 171 with sufficient fluid in a timely manner, automatically or manually, when the system has been running for a long time or when the total amount of fluid medium inside the cylinder 171 is lost due to minor leakage, so as to maintain the preset fluid pressure level and volume balance inside the system. This is prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0065] Hydraulic cylinder 121 extends to push lifting plate 122 downward, causing the light strip to move along the travel trajectory assembly 13 downward. When roller 14 comes into contact with the automotive glass with PVB film, lifting plate 122 continues to move downward to compress spring 125. At the same time, lifting plate 122 moves downward, causing piston rod 173 to press down piston 172, drawing fluid from the upper end of cylinder 171 and creating a negative pressure environment. This causes the fluid in clamping bladder 16 to fall back into the upper end of cylinder 171 through channel 146, annular groove 144, trough 143, short pipe 1375, three-way pipe 179, hose 1715, flow channel 177, annular shell 174, and connecting pipe 1713. The system pressure drops, clamping bladder 16 contracts and resets, releasing the clamping and positioning of the light strip.

[0066] Simultaneously, the piston 172 descends and compresses the incompressible fluid inside the lower end of the cylinder 171, generating system pressure. This pressure is then transmitted through the connecting pipe 1712, the annular shell 175, the flow channel 176, the hose 1714, the tee pipe 178, the bend 1710, the circular groove 141, and the channel 142 to drive the pressure-holding bladder 15 to expand and apply pressure. The fluid pressure is automatically converted using the lifting mechanical stroke, allowing the pressure to adapt to changes in the bonding stroke. During the rotation of the roller 14, the channel maintains pressure continuously, ensuring a stable bonding state throughout the process. When the lifting plate 122 moves upward and resets, the cavity volume changes, and the corresponding system pressure drops and rises, causing the pressure-holding bladder 15 to contract and release the pressure. The clamping bladder 16 expands to achieve clamping and limiting.

[0067] Specifically, a vehicle glass limiting component 18 is installed on the top of the frame 11. The vehicle glass limiting component 18 is existing technology, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. It is used to place, clamp, limit and fix the vehicle glass with PVB film to be processed, so as to ensure that the glass processing posture is stable, does not deviate or shake, and provides a precise reference for subsequent △-shaped LED light strip bonding.

[0068] The device also includes an LED strip cutting device, which is not shown in the figure and is existing technology. The working principle of this part is also existing technology and can be clearly understood by those skilled in the art. Its function is to automatically cut and separate the LED strip after it is completely attached to the surface of the automotive glass in a △ shape, complete the single bonding process, prepare materials in advance for the next LED strip bonding operation, and realize continuous cycle processing.

[0069] It should be noted that all materials used in the structure of this device meet the standards for automotive parts processing equipment, mechanical strength requirements, and dust-free processing conditions. All components that come into indirect or direct contact with LED light strips, automotive glass, and PVB film are made of high-strength, wear-resistant, corrosion-resistant, non-exudating, and scratch-free medical and industrial-grade environmentally friendly materials. These materials will not scratch the curved surface of the glass, damage the structure of the PVB film, or scratch the surface of the LED light strip. They are also suitable for long-term reciprocating mechanical motion, fluid pressure circulation, and high-frequency bonding processing conditions, and are not prone to deformation, rust, wear, or aging. The remaining frame, transmission, and guide bearing structures are all made of high-strength alloy steel, which has good structural rigidity and dimensional stability, ensuring long-term equipment assembly accuracy and bonding processing accuracy. The overall materials are insulating, dustproof, and temperature-resistant, making them suitable for intelligent automotive glass processing and production environments. They meet mass production standards and eliminate the risk of material contamination, workpiece damage, and premature equipment aging.

[0070] During use, the workpiece is clamped and the LED strip is pre-clamped: the curved automotive glass with PVB film is fixed on the limiting fixture of the frame 11, the rolled LED strip is placed on the unwinding frame 1364 of the traveling mechanism, and the end of the LED strip is inserted into the channel of the roller 14. When the equipment is on standby, the lifting mechanism is raised, the piston 172 inside the pressure component 17 is in a high position, the upper end of the cylinder 171 squeezes the fluid, the clamping bladder 16 expands and clamps the end of the LED strip, the pressure bladder 15 contracts and there is no pressure, and the LED strip remains fixed and does not loosen.

[0071] Downward pressure linkage switching (clamping release + curved surface clamping): Hydraulic cylinder 121 drives lifting plate 122 and the entire walking mechanism to move downward as a whole. Roller 14 first contacts the curved surface of the glass. Lifting plate 122 continues to move downward to compress buffer spring. At the same time, piston rod 173 presses down on piston 172 inside cylinder 171. Fluid in the lower end cavity is pressurized and transported to pressure bladder 15 to expand it. It flexibly clamps the light strip to adhere to the film. The upper end cavity forms negative pressure. Clamping bladder 16 contracts and automatically releases the end of the light strip. Unwinding is unrestrained. Spring 125 provides buffering and automatically adapts to the slight drop difference of the glass surface to avoid hard pressure damage to the workpiece.

[0072] Automatic triangular trajectory bonding and feeding: The geared motor 1367 drives the rotating column 1365 and the drive frame 1366 to drive the pulley 1361 to move along the double-layer triangular guide rail in a closed loop. The tube body 1363 carries the roller 14 to move along the preset △-shaped path. The unwinding frame 1364 passively releases the light strip in sync. The pressure holding bladder 15 continuously provides uniform bonding pressure and flexibly presses the glass along the curvature throughout the process, eliminating air bubbles and wrinkles.

[0073] Lifting and Resetting, Automatic Re-clamping: After completing a single-circle triangular trajectory movement, the hydraulic cylinder 121 drives the entire mechanism to lift upwards, the piston 172 moves upwards and resets with the piston rod 173, the lower end of the cylinder 171 is depressurized and the upper end is discharged fluid, the clamping bladder 16 re-expands and clamps the cut end of the light strip, preparing for the next round of bonding operation, the matching cutting device cuts the formed light strip, and the workpiece can be removed for repeated processing.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
