Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, and more particularly to an LED lamp and its assembly equipment and method. Background Technology

[0002] LED lighting fixtures, as a new generation of lighting products, have been widely used due to their advantages such as energy saving, environmental friendliness, and long lifespan. In the manufacturing of LED lighting fixtures, especially those with a conical lamp housing structure, the assembly quality directly affects the product's heat dissipation performance, optical effect, and lifespan. The key assembly steps involve reliably bonding the LED panel to the lamp housing using thermally conductive adhesive and pressing and sealing the lens.

[0003] Currently, this assembly process largely relies on manual operation or semi-automated equipment. Operators manually place the lamp board into the lamp housing coated with adhesive and then perform initial pressing. This method has significant drawbacks: First, manual placement makes it difficult to ensure precise alignment and parallel pressing between the lamp board and the heat-conducting surface of the lamp housing, easily leading to uneven pressing force, inconsistent thickness of the heat-conducting adhesive layer, air bubbles, and thermal resistance bottlenecks. This severely affects the heat dissipation efficiency of the LED chip, thus shortening the lamp's lifespan. Second, excess adhesive overflowing during pressing cannot be effectively controlled and often spreads uncontrollably to the sidewalls of the lamp housing and even the lens mounting surface. This not only affects aesthetics but may also contaminate optical components or interfere with subsequent lens sealing assembly, causing secondary quality problems. Furthermore, simple vertical pressing makes it difficult to de-bubble and optimize adhesive distribution, and lacks an online cleaning function for residual adhesive on the pressing tools, easily leading to cross-contamination and failing to meet the requirements of high-efficiency, high-quality, and consistent production. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an LED lamp and its assembly equipment and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An LED lamp includes an LED lamp body assembled by an assembly device. The LED lamp body includes a conical lamp housing, an annular support plate is fixed inside the conical lamp housing, a lamp plate is glued to the annular support plate, and a lens is snapped onto the end of the conical lamp housing. The conical lamp housing has a flow guide groove at the annular support plate.

[0006] An assembly device for an LED lamp includes the aforementioned assembly apparatus for an LED lamp, the assembly apparatus including a frame and further comprising: A belt conveyor is fixed on the upper side of a frame. Along its conveying direction, the belt conveyor is sequentially provided with an injection section for injecting glue into a conical lamp housing, a first pressing section for pressing the lamp plate and the conical lamp housing together, and a second pressing section for pressing the lens and the end of the conical lamp housing together. A first robotic arm for gripping the lamp plate is provided between the injection section and the first pressing section, and a second robotic arm for gripping the lens is provided between the first pressing section and the second pressing section. The first pressing part and the second pressing part have the same structure, both including a mounting frame fixedly connected to the belt conveyor, a hydraulic cylinder fixed on the mounting frame, and a pressing block disposed at the bottom of the piston rod of the hydraulic cylinder; The first pressing part has a scraper plate on the pressing block, and the first pressing part has a cleaning component for cleaning the adhesive on the scraper plate on the mounting bracket.

[0007] Preferably, the belt conveyor includes side plates fixed on both sides of the frame, a conveyor shaft rotatably disposed between the two side plates, a conveyor roller disposed on each conveyor shaft, a conveyor belt for connecting the two conveyor rollers, and a conveyor motor fixed on the side plates for driving one of the conveyor shafts to rotate. The mounting brackets for the glue injection section, the first pressing section, and the second pressing section are all fixed on the side plate, and a support plate for supporting the conveyor belt is provided between the two side plates. Several positioning seats are equidistantly arranged on the conveyor belt, and the positioning seats are provided with conical placement grooves that cooperate with the conical lamp housing.

[0008] Preferably, the pressure block includes a sleeve fixedly connected to the piston rod, a pressure ring movably connected inside the sleeve, a connecting ring disposed on the top of the pressure ring and rotatably connected to the pressure ring, and a first elastic element disposed between the connecting ring and the inner wall of the sleeve.

[0009] Preferably, a fixed guide post is fixedly provided on the inner wall of the sleeve, a spiral groove is provided on the pressure ring to cooperate with the fixed guide post, and the scraper is provided on the pressure ring, and the scraper and the bottom wall of the pressure ring are on the same plane. The scraper blade has a guide slope at the end away from the pressure ring that matches the inner wall of the conical lamp housing; the scraper blade is slidably disposed with the pressure ring, and an end plate is fixed at the end of the scraper blade placed inside the pressure ring, with a second elastic element disposed between the end plate and the inner wall of the pressure ring.

[0010] Preferably, the adhesive removal assembly includes a fixed seat fixed on the mounting bracket of the first pressing part, and the fixed seat has a movable groove in the middle for moving the adhesive scraper, and the two sides of the bottom inner wall of the movable groove move against the outer wall of the adhesive scraper.

[0011] Preferably, the adhesive removal assembly further includes wiping sections symmetrically arranged on both sides of the fixed seat. Each wiping section includes a housing fixedly connected to the fixed seat, a first winding rod and a second winding rod rotatably connected inside the housing, and a cleaning cloth disposed between the first winding rod and the second winding rod. The fixed seat is provided with guide tubes at the bottom sides of the movable groove, and the cleaning cloth of each wiping section is slidably connected to the guide tube on the same side.

[0012] Preferably, a drive gear is fixed on the first winding rod, and a driven gear that meshes with the drive gear is provided on the second winding rod; The sleeve is fixed with a rack plate that meshes with the drive gear. The drive gear is a one-way gear and has a flywheel structure inside it. When the rack plate moves upward and engages with the drive gear, the drive gear can drive the take-up rod to rotate; when the rack plate moves downward and engages with the drive gear, the drive gear idles and cannot drive the take-up rod to rotate.

[0013] Preferably, the guide tube is rotatably connected to the fixed base, and the guide tube has a plurality of liquid outlet holes along its axial direction. A third elastic element is connected inside the guide tube through a spring seat, and a conical plug for sealing the liquid outlet holes is connected to the end of the third elastic element away from the spring seat. A liquid storage shell is fixedly provided on the outside of the fixed base, and a rotating joint is provided between the liquid storage shell and the guide tube. The rotating joint is used to connect the liquid storage shell and the guide tube.

[0014] The present invention also discloses a method for using the aforementioned LED lamp assembly equipment, comprising the following steps: S1: Material feeding and glue injection The staff places the conical lamp housing with the opening facing upward on the positioning seat of the conveyor belt. The conical placement groove ensures its stability. The belt conveyor runs, transporting the conical lamp housing to the area below the glue injection section and then stops. The glue injection section injects a certain amount of thermally conductive adhesive into the designated area on the annular support plate inside the lamp housing. S2: Placement of the light panel The conical lamp housing moves to the next station along the conveyor line. The first robotic arm grabs the lamp plate and precisely places it on the adhesive on the annular support plate and the inner wall of the conical lamp housing. The conical lamp housing continues to move to below the first pressing part and pauses. S3: Initial pressing The hydraulic cylinder drives the piston rod and the entire pressure block assembly to move downwards. The guide slope at the front end of the scraper first contacts the inner wall of the conical lamp housing. As it is pressed down, the scraper is compressed and retracts into the pressure ring. The second elastic element is stretched until the bottom of the pressure ring contacts the lamp plate. After the pressure ring contacts the lamp panel, the piston rod continues to move downward, and the sleeve moves downward relative to the pressure ring, compressing the first elastic element, thus providing the lamp panel with a buffered, continuous pressure, rather than a rigid impact; S4: Clean up excess adhesive The excess glue that is squeezed out is partly squeezed into the guide groove on the annular support plate; partly overflows onto the upper surface of the lamp plate. During the downward movement of the sleeve, the fixed guide post interacts with the spiral groove on the pressure ring, converting the linear motion of the downward pressure into the rotational motion of the pressure ring and the scraper. This rotational motion generates shear force on the glue, which helps to remove air bubbles and make the glue evenly distributed. S5: Self-cleaning scraper After pressing is completed, the hydraulic cylinder lifts the pressure block assembly. When the scraper rises to the movable groove of the fixed seat of the cleaning component, its two sides come into close contact with the cleaning cloth led out from the guide tube to complete the wiping. As the pressure block continues to rise, the rack plate on the sleeve meshes with the drive gear. Since the drive gear is a one-way gear, it drives the first winding rod to rotate, releasing a new piece of cleaning cloth. At the same time, the second winding rod retracts the dirty cloth. This process is completed automatically. The friction generated when the cleaning cloth is rolled up drives the guide tube to rotate. The centrifugal force generated by the rotation causes the internal conical plug to overcome the force of the third elastic element and leave the liquid outlet. The cleaning liquid in the liquid storage shell is thrown out, wets the cleaning cloth, and enhances the cleaning effect. After the rotation stops, the conical plug resets under the action of elasticity and closes the liquid outlet. S6: Final pressing After the conical lamp housing with the lamp panel pressed together is completed, it continues to move to the bottom of the second pressing part and pauses. The second robotic arm grabs the lens and places it at the port of the conical lamp housing. It controls the pressing block of the second pressing part to press down and press the lens down so that it is locked into the buckle at the end of the conical lamp housing. The assembled LED lamp body is transported by belt conveyor to the unloading station for collection or to proceed to the next process.

[0015] Compared with the prior art, the present invention provides an LED lamp and its assembly equipment and method, which have the following beneficial effects: 1. In this invention, a complete automated production line is constructed by setting up a belt conveyor, a positioning seat, and a glue injection section, a first pressing section, and a second pressing section arranged sequentially along the conveying direction, and cooperating with the first and second robotic arms. The conical lamp housing is driven by the belt conveyor and flows through each workstation in sequence, automatically completing all processes such as glue injection, lamp board placement, lamp board pressing, lens placement, and lens pressing. The originally isolated and manpower-dependent processes are integrated into a continuous and automatic process, eliminating human interference. This not only greatly improves assembly efficiency but also ensures the precise controllability of each link, fundamentally guaranteeing the consistency and stability of product assembly quality, and solving the technical problems of low efficiency and unstable quality caused by manual operation.

[0016] 2. In this invention, the pressure ring forms an elastic floating connection with the sleeve using the connecting ring and the first elastic element, making the pressing process a buffered pressure rather than a rigid impact. At the same time, when the sleeve moves down, the fixed guide post cooperates with the spiral groove to drive the pressure ring and the scraper to rotate. The combined action of elastic downward pressure and rotational shearing avoids damaging the lamp panel on the one hand, and generates an effective rotational shearing force on the adhesive on the other hand. This can fully eliminate air bubbles, promote the flow and uniform spread of the adhesive, thereby forming an ultra-thin and dense thermally conductive adhesive layer, which greatly reduces the interfacial thermal resistance and fundamentally optimizes the heat dissipation performance and reliability of the LED lamp. This solves the technical problem of poor heat dissipation performance caused by uneven force and air bubbles in the adhesive layer in traditional pressing.

[0017] 3. In this invention, a guide channel is provided to accommodate the expected excess glue, while the rotating scraper can remove the residual glue on the upper surface of the lamp plate. This achieves proactive management of the overflow of glue, ensuring the cleanliness of key areas inside the lamp housing. It also solves the problem of excess glue overflowing disorderly during the pressing process, contaminating the side wall of the lamp housing and the lens mounting surface, and affecting the product's appearance and subsequent assembly sealing.

[0018] 4. In this invention, the adhesive cleaning component can wipe the scraper when the pressure head is lifted, and at the same time the rack plate drives the one-way gear mechanism to update the cleaning cloth. This solves the problem that if the residual adhesive on the scraper is not cleaned in time, it will contaminate subsequent products, reduce the scraping effect, and even cause the mechanism to jam, requiring frequent manual intervention. This enables the equipment to have self-cleaning ability and ensures long-term stable operation of the equipment. In contrast, simple scraping is difficult to completely remove viscous liquid and is prone to leaving adhesive residue on the blade or contact surface, causing adhesive transfer.

[0019] 5. In this invention, the cleaning cloth rubs against the guide tube during winding, causing the guide tube to rotate. The rotation of the guide tube causes the internally elastic conical plug to overcome gravity and spring force under the action of centrifugal force and move away from the outlet position. This allows the liquid inside the guide tube, such as alcohol, to be sprayed onto the cleaning cloth during operation, resulting in better wiping effect of the cleaning cloth on the scraper. When the guide tube stops rotating, the conical plug loses centrifugal force and, under natural conditions, relies on spring force to block the outlet, preventing the liquid from continuing to spill. This ensures that the scraper is clean before each operation, effectively preventing cross-contamination, maintaining scraping efficiency, and achieving long-term unmanned and stable operation of the equipment.

[0020] The elastic pressing structure, the rotary scraping design, and the self-cleaning adhesive removal component of this invention form an organic whole: the elastic pressing provides a stable pressing foundation for the rotary scraping, the rotary scraping reduces the load of cleaning excess adhesive for the adhesive removal component, and the self-cleaning component ensures long-term automated operation of the equipment. The three work together to achieve high-efficiency and high-quality production of LED lamp assembly. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] like Figure 1 and Figure 11 As shown, this embodiment proposes an LED lamp, including an LED lamp body assembled by an assembly device. The LED lamp body includes a conical lamp housing 9, and an annular support plate 901 is fixed inside the conical lamp housing 9. The annular support plate 901 provides a stable and flat mounting reference surface for the lamp plate 902, ensuring that the lamp plate 902 can achieve large-area uniform contact with it through adhesive. The lamp plate 902 is glued to the annular support plate 901 by adhesive. A lens 903 is also snapped onto the end of the conical lamp housing 9 by a buckle. The buckle design is prior art and will not be described in detail here. Among them, the conical lamp housing 9 has a guide groove 10 at the annular support plate 901; Specifically, the LED light panel 902 is placed at a designated position on the annular support plate 901 inside the conical lamp housing 9. Glue is applied between the light panel 902 and the annular support plate 901. The light panel 902 is bonded and fixed to the annular support plate 901 by pressing and other methods. During the pressing process, excess glue squeezed out from the joint flows into the preset guide groove 10 instead of spreading randomly. Finally, the lens 903 is aligned with the port of the conical lamp housing 9 and pressed down to fix it by a snap-fit ​​connection, completing the assembly of the entire lamp body. This effectively avoids the disorderly overflow of glue to the side wall of the conical lamp housing 9 or the lens 903 installation area, prevents glue contamination from affecting optical performance, and ensures the sealing of the subsequent lens 903 assembly, ultimately ensuring the cleanliness of the product's interior and the overall assembly quality.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, this embodiment proposes an LED lamp assembly device, including the aforementioned LED lamp assembly apparatus. The assembly apparatus includes a frame 1 and further includes: Belt conveyor 2 is fixed on the upper side of frame 1. Belt conveyor 2 is provided with, in sequence along its conveying direction, an injection part 3 for injecting glue into the conical lamp housing 9, a first pressing part 4 for pressing the lamp plate 902 and the conical lamp housing 9, and a second pressing part 5 for pressing the lens 903 and the end of the conical lamp housing 9. A first robotic arm for gripping the lamp plate 902 is provided between the injection part 3 and the first pressing part 4, and a second robotic arm for gripping the lens 903 is provided between the first pressing part 4 and the second pressing part 5. The first and second robotic arms are existing robotic arm technologies and are not shown in the figure; they will not be described in detail here. The first pressing part 4 and the second pressing part 5 have the same structure, both including a mounting frame 6 fixedly connected to the belt conveyor 2, a hydraulic cylinder 601 fixed on the mounting frame 6, and a pressing block 602 provided at the bottom of the piston rod 6011 of the hydraulic cylinder 601. The first pressing part 4 has a scraper 7 on the pressing block 602, and a cleaning component for cleaning the adhesive on the scraper 7 is provided on the mounting frame 6 of the first pressing part 4. The pressing part and the cleaning component are independently modular, which facilitates equipment maintenance and replacement and reduces production line downtime costs. Specifically, the conical lamp housing 9 is placed on the belt conveyor 2 and transported to the glue injection station 3 to complete the glue injection. After glue injection, the conical lamp housing 9 is sent to the next station. The first robotic arm grabs the lamp plate 902 and accurately places it on the annular support plate 901 inside the conical lamp housing 9. The conical lamp housing 9 enters the first pressing station 4. The hydraulic cylinder 601 drives the pressing block 602 to press down, so that the lamp plate 902 is bonded and fixed to the conical lamp housing 9. During this process, the glue scraper 7 on the pressing block 602 moves synchronously to scrape off the excess glue that may overflow from the upper surface of the lamp plate 902 due to the pressure. This prevents the glue from contaminating the internal optical space of the conical lamp housing 9 or interfering with the subsequent lens 903 assembly after curing. This directly improves the internal cleanliness of the product and the overall assembly quality, and reduces the defect rate caused by glue overflow. After pressing, the pressing block 602 is lifted. When it is lifted to a specific position, the adhesive cleaning component automatically cleans the residual adhesive on the surface of the scraper 7, preparing it for the next pressing operation. This avoids problems such as reduced scraping effect, scratching of products, or even mechanism jamming caused by the accumulation and hardening of adhesive on the scraper 7. This ensures the stability and reliability of the equipment during long-term continuous operation and reduces maintenance downtime. The conical lamp housing 9, which has completed the pressing of the lamp panel 902, is continued to be conveyed. The second robotic arm grabs the lens 903 and places it at the port of the conical lamp housing 9. Subsequently, the conical lamp housing 9 enters the second pressing section 5 station, where the pressing block 602 presses down to press the lens 903 into place through the snap-fit ​​structure. The assembled LED lamp body is then sent to the unloading area by the belt conveyor 2. By connecting multiple specialized machines such as glue injection and pressing via belt conveyor 2, and cooperating with robotic arms for automatic loading and unloading, the originally scattered processes are integrated into a complete automated production line, which greatly reduces manual intervention, significantly improves the assembly efficiency of LED lights and the consistency of production rhythm, and is suitable for large-scale production.

[0027] like Figure 1 , Figure 2 and Figure 7 As shown, in a preferred embodiment, based on the above method, the belt conveyor 2 further includes side plates 201 fixed on both sides of the frame 1, a conveyor shaft 202 rotatably disposed between the two side plates 201, a conveyor roller 203 disposed on each conveyor shaft 202, a conveyor belt 204 for connecting the two conveyor rollers 203, and a conveyor motor 205 fixed on the side plate 201 for driving one of the conveyor shafts 202 to rotate. The mounting brackets 6 of the glue injection part 3, the first pressing part 4, and the second pressing part 5 are all fixed on the side plate 201. A support plate 206 for supporting the conveyor belt 204 is also provided between the two side plates 201. Several positioning seats 207 are equidistantly arranged on the conveyor belt 204. The positioning seats 207 are provided with conical placement grooves 208 that cooperate with the conical lamp housing 9. Specifically, the conical lamp housing 9 is placed in the conical placement groove 208 of the positioning seat 207, and its conical structure achieves self-centering, ensuring that the conical lamp housing 9 has a consistent posture and accurate position. The control conveyor motor 205 is started, and the conveyor belt 204 is driven to run intermittently or continuously through the conveyor shaft 202 and the conveyor roller 203. The support plate 206 provides stable support from below to prevent the belt from sagging and deforming due to the load. The positioning seat 207 carrying the conical lamp housing 9 passes through the glue injection section 3, the first pressing section 4 and the second pressing section 5 in sequence with the conveyor belt 204. Since the mounting brackets 6 of all functional parts are fixed to the same pair of side plates 201, the accuracy and stability of each station relative to the conveying path are guaranteed. After the assembled lamp body is unloaded at the end, the empty positioning seat 207 returns to the starting end with the conveyor belt 204 to start the next cycle.

[0028] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the pressure block 602 further includes a sleeve 6021 fixedly connected to the piston rod 6011, a pressure ring 6022 movably connected inside the sleeve 6021, a connecting ring 6023 disposed on the top of the pressure ring 6022 and rotatably connected to the pressure ring 6022, and a first elastic element 6024 disposed between the connecting ring 6023 and the inner wall of the sleeve 6021. The first elastic element 6024 is usually a spring. Specifically, when the hydraulic cylinder 601 drives the piston rod 6011 to press down, the entire pressure block 602 assembly descends accordingly. The bottom surface of the pressure ring 6022 first contacts the lamp plate 902. After the pressure ring 6022 contacts the workpiece, it stops descending due to the reaction force of the workpiece. At this time, the piston rod 6011 continues to push the sleeve 6021 downward, causing the sleeve 6021 to move relative to the stationary pressure ring 6022, thereby compressing the first elastic element 6024 located between the two. The compressed first elastic element 6024 generates a continuous and gradually increasing elastic reaction force. This force is evenly applied to the surface of the workpiece through the pressure ring 6022 to achieve a stable pressure holding effect. After the pressing is completed, the hydraulic cylinder 601 drives the piston rod 6011 to rise, and the sleeve 6021 rises accordingly. The first elastic element 6024 releases its elastic potential energy, pushing the connecting ring 6023 and the pressure ring 6022 to reset and separate from the workpiece. By setting the first elastic element 6024, the direct rigid downward pressure of the hydraulic cylinder 601 is converted into a continuous and gentle elastic pressure transmitted through the spring. This soft contact method avoids the instantaneous impact force from damaging the fragile lamp board 902 or its chips, greatly reducing the risk of damage to the lamp board 902 due to excessive force or unevenness during the pressing process. It also gives it a certain self-adjusting leveling capability. When there is a slight unevenness on the surface or placement of the lamp board 902, the pressure ring 6022 can automatically adjust its posture after the initial contact, so that the pressure is evenly distributed across the entire contact surface. This ensures that the adhesive layer thickness between the lamp board 902 and the conical lamp housing 9 is consistent, avoiding insufficient or excessive local pressure. This significantly improves the reliability and effect of thermally conductive bonding. Compared with the prior art, the thermal resistance of the heat dissipation interface is effectively reduced. Compared with the rigid contact of traditional manual pressing, the elastic pressing structure of this application greatly reduces the breakage rate of the lamp board 902.

[0029] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, a fixed guide post 8 is fixedly provided on the inner wall of the sleeve 6021, a spiral groove 801 that cooperates with the fixed guide post 8 is provided on the pressure ring 6022, and a scraper 7 is provided on the pressure ring 6022, and the scraper 7 and the bottom wall of the pressure ring 6022 are on the same plane. The end of the scraper 7 away from the pressure ring 6022 is provided with a guide slope that matches the inner wall of the conical lamp housing 9; the scraper 7 is slidably disposed with the pressure ring 6022, and the end of the scraper 7 placed inside the pressure ring 6022 is fixedly provided with an end plate 701. A second elastic element 702 is provided between the end plate 701 and the inner wall of the pressure ring 6022, and the connection point between the scraper 7 and the second elastic element 702 is not in the scraping area, so there is no situation where the glue solidifies and causes it to get stuck; Specifically, when the pressure block 602 assembly is pressed down, the guide slope at the front end of the scraper 7 first contacts the inner wall of the conical lamp housing 9. As the pressing continues, the constraint of the conical wall overcomes the second elastic element 702. The elastic force pushes the scraper 7 to radially contract into the pressure ring 6022 until the bottom surface of the pressure ring 6022 contacts the lamp plate 902. The components on the lamp plate 902 should be concentrated in the central area to avoid being squeezed and collided by the pressure ring 6022. After the pressure ring 6022 contacts the lamp plate 902, the sleeve 6021 continues to move down under the drive of the piston rod 6011. At this time, the fixed guide post 8 and the spiral groove 801 on the pressure ring 6022 generate relative movement. The guide post slides along the spiral groove 801, forcing the pressure ring 6022 to rotate relative to the sleeve 6021. The rotation of the pressure ring 6022 drives the scraper 7 at its bottom to rotate together. At this time, under the thrust of the second elastic element 702, the side of the scraper 7 always keeps in contact with the inner wall of the conical lamp housing 9 or the upper surface of the lamp plate 902, and scrapes the glue that may overflow in a circular motion. After pressing, the pressure block 602 is lifted, and each component moves back to its original position in the opposite order. It should be noted that the pressure ring 6022 rotates relative to the conical lamp housing 9. The rotation action can generate shear force on the liquid adhesive, which can effectively break and eliminate air bubbles, promote the uniform flow of adhesive, and thus form a dense adhesive layer with better thermal conductivity.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adhesive removal assembly further includes a fixed seat 11 fixed on the mounting bracket 6 of the first pressing part 4. The fixed seat 11 has a movable groove 111 for moving the scraper 7 in the middle. The two sides of the bottom inner wall of the movable groove 111 move against the outer wall of the scraper 7. The size design of the movable groove 111 allows the scraper 7 to pass smoothly in the vertical direction. Specifically, when the pressure block 602 moves the scraper 7 downwards for pressing, the scraper 7 first passes through the movable groove 111 of the fixed base 11. Since the scraper 7 is clean at this time, it does not perform a cleaning function during this passage. After pressing, the pressure block 602 is lifted, causing the scraper 7 with residual adhesive to move upwards and pass through the movable groove 111 again. When the scraper 7 moves upwards through the bottom of the movable groove 111, the adhesive on its side walls will violently scrape and shear against the inner edges of the bottom sides of the movable groove 111, removing most of the residual adhesive from the side walls of the scraper 7. Liquid thermally conductive adhesive is used in the LED light board assembly. During the pressing process, the scraper... The scraper plate 7 removes sticky, uncured adhesive. This type of contaminant not only adheres to the surface of the scraper plate 7, but if not thoroughly cleaned, it can easily contaminate the next product in subsequent work, leading to cross-contamination. Simple scraping (such as with a grooved cleaning blade) is insufficient to completely remove the sticky liquid, leaving adhesive residue on the blade edge or contact surface, causing adhesive transfer problems. Furthermore, it requires frequent manual intervention, reducing production efficiency and introducing instability due to human operation. This effectively prevents the adhesive from accumulating and curing layer by layer on the scraper plate 7, thus avoiding contamination of new workpieces during the next pressing due to unclean scraper plate 7, ensuring the cleanliness of the product assembly process, and reducing the product defect rate caused by contamination.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adhesive removal assembly further includes wiping sections symmetrically arranged on both sides of the fixed base 11. Each wiping section includes a housing 12 fixedly connected to the fixed base 11, a first winding rod 121 and a second winding rod 122 rotatably connected within the housing 12, and a cleaning cloth 123 disposed between the first winding rod 121 and the second winding rod 122. The fixed base 11 is provided with guide tubes 13 at the bottom sides of the movable groove 111. The cleaning cloth 123 of each wiping section is slidably connected to the guide tube 13 on the same side. It should be noted that the first winding rod 121 and the second winding rod 122 are connected to the housing 12 via damping bearings or friction bushings. This connection provides sufficient static friction torque so that the winding rod will not rotate under the normal tension of the cleaning cloth 123 when there is no external driving force, i.e., when the rack and gear are not meshed. Only when the rack plate 14 provides a sufficiently large driving force can the static friction torque be overcome and the winding rod be driven to rotate. Furthermore, a drive gear 1211 is fixed on the first winding rod 121, and a driven gear 1221 that meshes with the drive gear 1211 is provided on the second winding rod 122. A rack plate 14 that meshes with the drive gear 1211 is fixed on the sleeve 6021. The drive gear 1211 is a one-way gear and has a flywheel structure inside it. When the rack plate 14 moves upward and meshes with the drive gear 1211, the drive gear 1211 can drive the take-up rod 121 to rotate; when the rack plate 14 moves downward and meshes with the drive gear 1211, the drive gear 1211 rotates idly and cannot drive the take-up rod 121 to rotate. Specifically, when the pressing block 602 presses down for the pressing operation, the rack plate 14 on the sleeve 6021 descends accordingly. Even if the rack plate 14 contacts the drive gear 1211, due to the idling characteristic of the one-way gear, the winding rod 121 will not rotate, and the cleaning cloth 123 remains stationary. This avoids malfunctions during the pressing operation of the pressing block 602, thus preventing waste of the cleaning cloth 123. Compared with a two-way gear design, this reduces the waste of the cleaning cloth 123 and lowers the cost of production materials. During the pressing process, the scraper 7 becomes contaminated with adhesive. The residual adhesive is pressed and the pressing block 602 is lifted. The sleeve 6021 drives the rack plate 14 to rise. During the rise of the rack plate 14, it meshes with the drive gear 1211. Since it is an upward meshing, the one-way gear is locked. The linear motion of the rack plate 14 is converted into the rotation of the drive gear 1211, which drives the first winding rod 121 to rotate and release a new section of cleaning cloth 123. At the same time, through gear meshing, the second winding rod 122 rotates synchronously and rolls up the used and dirty section of cleaning cloth 123. The replacement process of cleaning cloth 123 is fully automated, requiring no additional power source. After each pressing cycle, the scraper 7 comes into contact with a brand-new cleaning cloth 123 for wiping, fundamentally solving the problem of fixed cleaning surfaces becoming contaminated and ineffective due to repeated use, and continuously ensuring excellent cleaning results. Its multi-layer linkage mechanism is designed to achieve continuous and effective cleaning without manual intervention in fully automatic, uninterrupted assembly line operations. This process requires no additional power source or control program, and is entirely based on physical principles to automatically respond to the movement state of cleaning cloth 123. No additional external power or complex control unit is introduced, and its operation is synchronized with the main pressing action. 。

[0032] like Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the guide tube 13 is rotatably connected to the fixed base 11, and the guide tube 13 is provided with a plurality of liquid outlet holes 131 along its axial direction. The use of a simple nozzle faces the problems of clogging, dripping or inaccurate supply. A third elastic element 132 is connected to the guide tube 13 through a spring seat. The end of the third elastic element 132 away from the spring seat is connected to a conical plug 133 for sealing the liquid outlet holes 131. A liquid storage shell 15 is fixedly provided on the outside of the fixed base 11. A rotating joint 151 is provided between the liquid storage shell 15 and the guide tube 13. The rotating joint 151 is used to connect the liquid storage shell 15 and the guide tube 13. The joint allows the guide tube 13 to continuously receive cleaning fluid from the liquid storage shell 15 while rotating freely. The cleaning fluid is an organic solvent with excellent low-temperature fluidity and is suitable for production environments of -10℃ to 40℃. Specifically, when the equipment is in standby or pressing stage and the guide tube 13 is not rotating, the internal conical plug 133, under the thrust of the third elastic element 132, is tightly pressed against the inner wall of the liquid outlet 131, completely sealing the channel and preventing cleaning fluid leakage. When liquid application is required, i.e., when the cleaning cloth 123 is wound up, the guide tube 13 is driven to rotate. An anti-wear layer is provided on the outside of the guide tube 13, and clearance is reserved between each moving part to avoid jamming problems under high-frequency operation. The rotation of the guide tube 13 generates centrifugal force. Under the action of centrifugal force, the conical plug 133 overcomes the elastic force of the third elastic element 132 and its own weight, and moves radially outward, thereby disengaging from the opening of the liquid outlet 131 and opening the liquid channel. Under the action of gravity, the cleaning fluid flows from the liquid storage shell 15 into the guide tube 13 through the rotating joint 151 and is thrown out through the opened liquid outlet 131. The cleaning cloth 123, which comes into contact with the guide tube 13, is soaked in the liquid. When the guide tube 13 stops rotating, the centrifugal force disappears, and the elastic force of the third elastic element 132 pushes the conical plug 133 to reset, re-sealing the liquid outlet 131, and the liquid flow stops immediately. This process does not require additional electronic valves or control programs. It is based entirely on physical principles and automatically responds to the movement state of the cleaning cloth 123, ensuring that the cleaning liquid is precisely applied only when needed. This avoids waste and significantly enhances the dissolving and cleaning effect on stubborn adhesives. It should be noted that the power for the rotation of the guide tube 13 does not come directly from the processing of high-viscosity adhesives themselves, but from the friction generated when the cleaning cloth 123 is wound up. The magnitude of this friction is mainly determined by the damping of the winding mechanism and the tension of the cleaning cloth. These are controllable parameters inside the equipment. As long as the winding action is reliably driven by the rack plate 14 and the gear set, the guide tube 13 can obtain stable rotational power. 。

[0033] The present invention also discloses a method of using the aforementioned LED lamp assembly equipment, comprising the following steps: S1: Material feeding and glue injection The staff places the conical lamp housing 9 with the opening facing upward on the positioning seat 207 of the conveyor belt 204. The conical placement groove 208 ensures its stability. The belt conveyor 2 runs, transporting the conical lamp housing 9 to the bottom of the glue injection section 3 and pausing. The glue injection section 3 injects a certain amount of thermally conductive adhesive into the designated area on the annular support plate 901 inside the lamp housing. S2: Placement of lamp panel 902 The conical lamp housing 9 moves to the next station along the conveyor line. The first robotic arm grabs the lamp plate 902 and precisely places it on the annular support plate 901 and the glue on the inner wall of the conical lamp housing 9. The conical lamp housing 9 continues to move to below the first pressing part 4 and pauses. S3: Initial pressing The hydraulic cylinder 601 drives the piston rod 6011 and the entire pressure block 602 assembly to move downward. The guide slope at the front end of the scraper 7 first contacts the inner wall of the conical lamp housing 9. As it is pressed down, the scraper 7 is compressed and retracts into the pressure ring 6022. The second elastic element 702 is stretched until the bottom of the pressure ring 6022 contacts the lamp plate 902. After the pressure ring 6022 contacts the lamp plate 902, the piston rod 6011 continues to move downward, and the sleeve 6021 moves downward relative to the pressure ring 6022, compressing the first elastic element 6024, thereby providing the lamp plate 902 with a buffered, continuous pressure, rather than a rigid impact. S4: Clean up excess adhesive The excess glue that is squeezed out is partly squeezed into the guide groove 10 on the annular support plate 901; and partly overflows onto the upper surface of the lamp plate 902. During the downward movement of the sleeve 6021, the fixed guide post 8 interacts with the spiral groove 801 on the pressure ring 6022, converting the downward linear motion into the rotational motion of the pressure ring 6022 and the scraper 7. This rotational motion generates shear force on the glue, which helps to remove air bubbles and make the glue evenly distributed. S5: Scraper blade 7 self-cleaning After pressing is completed, the hydraulic cylinder 601 lifts the pressure block 602 assembly. When the scraper 7 rises to the movable groove 111 of the fixed seat 11 of the cleaning component, its two sides come into close contact with the cleaning cloth 123 led out from the guide tube 13 to complete the wiping. As the pressure block 602 continues to rise, the rack plate 14 on the sleeve 6021 meshes with the drive gear 1211. Since the drive gear 1211 is a one-way gear, it drives the first winding rod 121 to rotate, releasing a new cleaning cloth 123. At the same time, the second winding rod 122 recycles the dirty cloth. This process is completed automatically. The friction generated when the cleaning cloth 123 is rolled up drives the guide tube 13 to rotate. The centrifugal force generated by the rotation causes the internal conical plug 133 to overcome the force of the third elastic element 132 and leave the liquid outlet 131. The cleaning liquid in the liquid storage shell 15 is thrown out, soaking the cleaning cloth 123 and enhancing the cleaning effect. After the rotation stops, the conical plug 133 resets under the action of elasticity and closes the liquid outlet 131. S6: Final pressing After the conical lamp housing 9, which has completed the pressing of the lamp panel 902, continues to move to the bottom of the second pressing part 5 and pauses, the second robotic arm grabs the lens 903 and places it at the port of the conical lamp housing 9, controls the pressing block 602 of the second pressing part 5 to press down, pressing the lens 903 down so that it is snapped into the buckle at the end of the conical lamp housing 9. The assembled LED lamp body is transported by belt conveyor 2 to the unloading station for collection or to proceed to the next process.

10. A method of using the LED lamp assembly equipment according to claim 9, characterized in that, Includes the following steps: S1: Material feeding and glue injection The staff places the conical lamp housing (9) with the opening facing upward on the positioning seat (207) of the conveyor belt (204). The conical placement groove (208) ensures its stability. The belt conveyor (2) runs and transports the conical lamp housing (9) to the bottom of the glue injection section (3) and stops. The glue injection section (3) injects a certain amount of thermally conductive adhesive into the designated area on the annular support plate (901) inside the lamp housing. S2: Placement of light panel (902) The conical lamp housing (9) moves to the next station along the conveyor line. The first robotic arm grabs the lamp plate (902) and accurately places it on the glue on the inner wall of the annular support plate (901) and the conical lamp housing (9). The conical lamp housing (9) continues to move to the bottom of the first pressing part (4) and pauses. S3: Initial pressing The hydraulic cylinder (601) drives the piston rod (6011) and the entire pressure block (602) assembly to move downward. The guide slope at the front end of the scraper (7) first contacts the inner wall of the conical lamp housing (9). As it is pressed down, the scraper (7) is compressed and retracts into the pressure ring (6022). The second elastic element (702) is stretched until the bottom of the pressure ring (6022) contacts the lamp plate (902). After the pressure ring (6022) contacts the lamp plate (902), the piston rod (6011) continues to move downward, and the sleeve (6021) moves downward relative to the pressure ring (6022), compressing the first elastic element (6024), thereby providing the lamp plate (902) with a buffered, continuous pressure, rather than a rigid impact; S4: Clean up excess adhesive The excess glue that is squeezed out is partially squeezed into the guide groove (10) on the annular support plate (901); and partially overflows onto the upper surface of the lamp plate (902). During the downward movement of the sleeve (6021), the fixed guide post (8) interacts with the spiral groove (801) on the pressure ring (6022), converting the downward linear motion into the rotational motion of the pressure ring (6022) and the scraper (7). This rotational motion generates shear force on the glue, which helps to remove air bubbles and make the glue evenly distributed. S5: Scraper (7) self-cleaning After pressing is completed, the hydraulic cylinder (601) lifts the pressure block (602) assembly. When the scraper (7) rises to the movable groove (111) of the fixed seat (11) of the cleaning assembly, its two sides come into close contact with the cleaning cloth (123) led out from the guide tube (13) to complete the wiping. As the pressure block (602) continues to rise, the rack plate (14) on the sleeve (6021) meshes with the drive gear (1211). Since the drive gear (1211) is a one-way gear, it drives the first winding rod (121) to rotate, releasing a new piece of cleaning cloth (123). At the same time, the second winding rod (122) recycles the dirty cloth. This process is completed automatically. The friction generated when the cleaning cloth (123) is rolled up drives the guide tube (13) to rotate. The centrifugal force generated by the rotation causes the internal conical plug (133) to overcome the force of the third elastic element (132) and leave the liquid outlet (131). The cleaning liquid in the liquid storage shell (15) is thrown out, soaking the cleaning cloth (123) and enhancing the cleaning effect. After the rotation stops, the conical plug (133) resets under the action of elasticity and closes the liquid outlet (131). S6: Final pressing After the conical lamp housing (9) with the lamp panel (902) pressed together is completed, it continues to move to the bottom of the second pressing part (5) and pauses. The second robotic arm grabs the lens (903) and places it at the port of the conical lamp housing (9). It controls the pressing block (602) of the second pressing part (5) to press down and press the lens (903) down so that it is snapped into the buckle at the end of the conical lamp housing (9). The assembled LED lamp body is transported to the unloading station by belt conveyor (2) for collection or to enter the next process.
