Description

Technical Field

[0001] This invention relates to the technical field of cosmetic box assembly equipment, and in particular to a multifunctional assembly device and cosmetic box assembly system. Background Technology

[0002] The multi-functional assembly device for makeup boxes is designed for composite makeup boxes that integrate rotary transmission, multi-cavity load-bearing, internal sealing and outer shell protection. It is an integrated automated assembly equipment that automates the feeding, precise positioning, step-by-step assembly, accuracy detection, automatic unloading and workstation maintenance of five core components: mounting base, rotary transmission sleeve, functional load-bearing seat, inner sealing plate and inner shell cover. It is used to replace manual labor to complete the continuous and standardized assembly of makeup boxes.

[0003] Currently, most makeup box assembly uses semi-automatic turntable assembly equipment, with a simple turntable as the transfer carrier, and is equipped with an independent feeding mechanism, a single-process tightening mechanism, and manual or simple testing mechanism to complete the assembly. The fixing base is mostly a simple slot or flat load-bearing structure, which only serves as a basic load-bearing function. The assembly process lacks continuous positioning, layer fastening, closed-loop testing and automatic station maintenance modules, and relies heavily on manual assistance for alignment, transfer and verification. The overall level of automation and integration is low.

[0004] However, the existing equipment lacks automatic cleaning and lubrication functions for the fixed base. Residual impurities after assembly can easily affect the accuracy of subsequent assembly, and the parts wear out quickly. It is difficult to achieve fully automated continuous assembly, resulting in low assembly efficiency and low finished product qualification rate. Summary of the Invention

[0005] This application provides a multifunctional assembly device and a makeup box assembly system, which has the function of automatically cleaning and lubricating the fixing base.

[0006] This application provides a multifunctional assembly device and a makeup box assembly system, which adopts the following technical solution: A multifunctional assembly device and a makeup box assembly system, wherein the multifunctional assembly device includes: an assembly machine table, the table surface of which is provided with a fixed plate coaxially fixed and a rotatable drive plate. At least five feeding components, corresponding to the mounting base, rotating transmission sleeve, functional support seat, inner sealing plate and inner shell of the feeding makeup box respectively; The unloading and transfer assembly is arranged at the output end of each of the loading assemblies; The drive sleeve is arranged sequentially along the processing path of the drive sleeve, including a primary positioning component, a primary tightening component, a secondary tightening component, a secondary positioning component, an infrared positioning detection component, a transfer and unloading component, and a multi-functional processing module; the upper surface of the drive sleeve is evenly distributed with several fixed seats at equal angles, and the fixed seats are used to support the parts to be assembled and circulate with the drive sleeve. The mounting base includes a bottom anti-slip positioning pad, a central support bushing, a reference positioning groove, and a side limiting protrusion. The external threaded shaft of the mounting base is inserted into the central support bushing to achieve axial positioning. The reference positioning groove is fitted into the bottom of the mounting base to achieve planar positioning. The side limiting protrusion limits the circumferential position of the mounting base.

[0007] Preferably, the multi-functional processing module includes a cleaning component and a lubrication component. The cleaning component removes impurities inside the fixed seat through a high-pressure jet nozzle. The lubrication component includes a steering bracket and a lubrication head. The steering bracket drives the lubrication head to adjust in multiple dimensions to fit the central support bushing of the fixed seat.

[0008] Preferably, the integrated head of the cleaning component is provided with a positioning jaw that is adapted to the shape of the central support bushing, the high-pressure jet nozzle is located on the inner sidewall of the positioning jaw, and the integrated head is connected to the fixed workpiece by an electric telescopic rod to achieve telescopic docking.

[0009] Preferably, the lubrication head includes an outer sleeve, a silicone inner sleeve, and a silicone layer. The inner surface of the silicone layer forms a corrugated concave portion. A sealed air chamber is provided between the silicone inner sleeve and the outer sleeve. The sealed air chamber is adjusted by an external air pump to allow the silicone layer to expand and contract to fit the central support bushing of different sizes.

[0010] Preferably, the inner surface of the concave portion of the silicone layer is provided with an annular scraper and an arc-shaped scraper. The annular scraper and the arc-shaped scraper are staggered to form a rectangular oil reservoir. The annular scraper removes impurities from the surface of the central support bushing and recovers excess lubricating oil. The oil reservoir stores lubricating oil to maintain lubrication durability.

[0011] Preferably, the driving component of the lubrication head includes a gear ring, a drive motor, and a bevel gear. The drive motor drives the silicone layer to twist by meshing with the gear ring through the connected bevel gear, thereby squeezing the oil reservoir to release uniform lubricating oil.

[0012] Preferably, a cylinder is fixed to the top of the outer sleeve of the lubrication head. The cylinder drives the lubricating oil release component to move up and down to cooperate with the air chamber to inflate, causing the concave part of the silicone layer to deform outward to clean the residual impurities on the inner wall of the oil storage tank.

[0013] Preferably, the primary tightening component and the secondary tightening component apply rotational power to the rotary transmission sleeve in layers, the secondary positioning component detects the coaxiality and tightness of the rotary transmission sleeve, and the infrared positioning detection component screens the assembly accuracy of the finished makeup box.

[0014] Preferably, the lubrication component of the multifunctional processing module further includes a movable component, which consists of a limiting sleeve, a connecting rod, and a buffer spring. The movable component intermittently releases lubricating oil to the inner wall of the concave portion of the silicone layer by squeezing the sponge block through the pressure block.

[0015] Preferably, an assembly system for a multifunctional assembly device, based on the aforementioned multifunctional assembly device, includes the following steps: S1: Loading and positioning of reference components; The first feeding component conveys the mounting base, and the unloading and transfer component precisely inserts it into the fixed seat of the drive sleeve. The fixed seat achieves triple limiting of the mounting base in the plane, axis, and circumference through the bottom anti-slip pad, the central reference groove, the side limiting protrusions, and the central support bushing. The first positioning component completes the accuracy calibration, and the coaxial design of the fixed plate and the drive sleeve lays the concentricity benchmark for subsequent transfer. S2: Transmission component layer assembly verification; The drive sleeve is transferred to the second station. The feeding component supplies the rotary transmission sleeve, and the unloading and transfer component connects it to the threaded shaft of the mounting base. The primary and secondary tightening components tighten the sleeve in layers to prevent stress damage. The secondary positioning component checks the coaxiality and tightness. Defective products are automatically rejected, and qualified products are transferred to the next station. S3: The main body of the makeup box is assembled in steps; The drive plate sequentially flows to the third to fifth workstations, where the functional support base, inner sealing plate, and inner shell are loaded and assembled respectively. Each component is snapped together and threaded together in the process sequence. The inner sealing plate separates the transmission space from the makeup cavity, and the inner shell completes the outer shell sealing, forming a complete finished makeup box. S4: Finished product inspection, material handling and workstation maintenance; Infrared positioning and detection components verify the assembly accuracy and integrity of finished products. Qualified products are delivered to designated locations by transfer and unloading components. After unloading, the multi-functional processing module starts operation: high-pressure air jets remove impurities from the bushings, the wrap-around lubrication head adapts to the bushing size, the scraper completes secondary cleaning and oil storage, the lubricating oil release component supplies oil as needed, and the cylinder drive realizes self-cleaning of the oil storage tank. After maintenance, the system is reset and enters the next assembly cycle, realizing continuous automated production.

[0016] In summary, this application has the following beneficial effects: 1. To further address the issues of inaccurate positioning and component misalignment in makeup box assembly, this invention further optimizes the design by incorporating a fixing base consisting of a bottom anti-slip positioning pad, a central support bushing, a reference positioning groove, and side limiting protrusions. This provides triple limiting of the mounting base plane, axis, and circumference, significantly improving assembly concentricity and stability. Subsequently, the fixing base circulates with the drive sleeve, and the coaxial design of the fixing and drive sleeves ensures that the component positions remain unchanged throughout the transport process, establishing a precise reference for the entire assembly process.

[0017] 2. To further address the issues of stress damage and non-compliance with coaxiality caused by single tightening of the rotary transmission sleeve, this invention further optimizes the process by incorporating a primary tightening component and a secondary tightening component to apply rotational power in layers. This, combined with a secondary positioning component for real-time monitoring, ensures layered tightening of the transmission components, preventing component cracking and deformation. Simultaneously, it accurately verifies coaxiality and tightness, automatically rejecting defective products. Subsequently, this layered assembly design effectively reduces component wear and improves assembly consistency and finished product yield.

[0018] 3. To further address the issues of residual impurities affecting accuracy in the fixed seat and easy wear of the central support bushing, this invention also incorporates a multi-functional processing module integrating cleaning and lubrication. This module enables high-pressure air jet cleaning and adaptive encapsulation lubrication, removing impurities from the bushing and extending the service life of the components. Furthermore, the lubrication head can be adapted to bushings of different sizes through air chamber inflation and deflation, combining scraper cleaning with oil reservoir self-cleaning, achieving closed-loop maintenance at the workstation and ensuring continuous production stability.

[0019] 4. To further address the issues of low efficiency in the step-by-step assembly of multi-component cosmetic boxes and the lack of finished product inspection, this invention further optimizes the process by incorporating five independent feeding components, an infrared positioning and detection component, and a transfer and unloading component. This enables automated feeding and assembly of the five major components step-by-step, as well as precise finished product inspection and automatic unloading. Subsequently, the entire process is seamlessly integrated, reducing manual intervention and significantly improving assembly efficiency and standardization, thus adapting to the needs of large-scale production.

[0020] 5. To further address the issues of easy accumulation of impurities in the oil reservoir of the lubrication head and the tediousness of manual cleaning, this invention further optimizes the process by incorporating a biomimetic intestinal corrugated silicone layer and a cylinder-driven outward-folding self-cleaning biomimetic structure. This structure enables biomimetic self-cleaning of the oil reservoir and automatic removal of impurities, while the biomimetic corrugated structure enhances the adhesion and storage of lubricating oil. Subsequently, the outward-folding deformation of the silicone layer, combined with dynamic scraping by a scraper, forms a closed-loop biomimetic self-cleaning system with no blind spots, eliminating the need for manual disassembly and maintenance and ensuring cleanliness during long-term continuous production.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1: This invention discloses a multifunctional assembly device and a makeup box assembly system, such as... Figure 1 As shown, Figure 1 As shown, the makeup box 1, along the assembly process, includes, in sequence: a mounting base 101, a rotary transmission sleeve 102, a functional support seat 103, an inner sealing disc 104, and an inner shell cover 105. The structure and assembly relationship of each component are as follows: The mounting base 101 has an externally threaded shaft at its center, which is threadedly connected to the rotary transmission sleeve 102, providing a reference support for the overall assembly. The rotary transmission sleeve 102 is a hollow sleeve, with an internal thread on its inner wall that mates with the externally threaded shaft of the mounting base 101. A snap-fit ​​structure is provided at the top for connecting subsequent components and transmitting power. The functional support seat 103 is a platform with a central positioning structure and limit holes on both sides. A snap-fit ​​groove at the bottom snaps into the top of the rotary transmission sleeve 102 to support its movement. A snap-fit ​​structure is provided at the top for assembling the inner sealing disc 104. The inner sealing disc 104 is a flat disc with a central opening and snap-fit ​​structures at the edges, snapping into the functional support seat 103 from the top and bottom, serving to separate the internal transmission space from the upper makeup cavity. The inner shell 105 is a semi-enclosed shell structure that can directly accommodate the contents of the makeup. Its bottom is engaged with the inner sealing plate 104, enclosing all the internal structures below and serving as the outer shell for the internal components.

[0024] like Figure 2 As shown, specifically, the assembly device for the multifunctional makeup box 1 includes an assembly machine 2, a feeding component 3, and an unloading and transfer component 4. There are five feeding components 3, corresponding to the mounting base 101, rotary transmission sleeve 102, functional support seat 103, inner sealing plate 104, and inner shell cover 105 of the makeup box 1, respectively, for precise feeding of each component. The unloading and transfer component 4 is located at the output end of each feeding component 3, responsible for guiding the parts to be assembled within the feeding component 3 to the designated positions.

[0025] like Figure 2 As shown, furthermore, a fixed disk 5 and a drive sleeve disk 6 are coaxially arranged on the table surface of the assembly machine 2. The fixed disk 5 is fixedly connected to the table surface of the machine and serves as the assembly reference. The drive sleeve disk 6 rotates coaxially around the fixed disk 5, and one rotation constitutes a complete processing cycle. Several fixed seats 7 are evenly distributed at equal angles on the upper surface of the drive sleeve disk 6 to support the parts to be assembled and to complete the cyclic transfer with the drive sleeve disk 6.

[0026] like Figure 2As shown, along the processing path of the drive sleeve 6, the assembly table 2 is sequentially equipped with a primary positioning component 8, a primary tightening component 9, a secondary tightening component 10, a secondary positioning component 11, an infrared positioning detection component 12, a transfer and unloading component 13, and a multi-functional processing module 14. Each component works together to complete the entire assembly process. The specific single process flow is as follows: First, the first feeding component 3 completes the feeding of the mounting base 101. The corresponding unloading and transfer component 4 guides the mounting base 101 to be inserted into the fixed seat 7. Then, the mounting base 101 is accurately positioned by the primary positioning component 8. After positioning, the drive sleeve 6 is transferred to the second feeding component 3 to complete the feeding of the rotary transmission sleeve 102. Then, it is transferred to the primary tightening component 9 and the secondary tightening component 10 in sequence. The primary tightening component 9 screws the rotary transmission sleeve 102 onto the top of the mounting base 101 through a rotation action. The secondary tightening component 10 further tightens to ensure that the rotary transmission sleeve 102 and the mounting base 101 are properly assembled.

[0027] Next, the drive plate 6 transfers the assembly with the mounting base 101 and the rotary transmission sleeve 102 to the secondary positioning component 11 to test the assembly positioning accuracy of the rotary transmission sleeve 102. After the positioning is qualified, it passes through the third, fourth and fifth feeding components 3 in sequence to gradually complete the assembly of the functional support seat 103, the inner sealing plate 104 and the inner shell cover 105, forming the finished cosmetic box 1.

[0028] The finished makeup box 1 is transferred to the infrared positioning detection component 12 to check the assembly accuracy and integrity of the finished product. The qualified finished product is clamped by the transfer unloading component 13 and transferred to the designated unloading position. After unloading, the multi-functional processing module 14 cleans and lubricates the fixed seat 7 to prepare for the next assembly cycle, thus completing a single complete process flow.

[0029] The core principle of this multifunctional makeup box 1 assembly device and system is based on the assembly logic of each component of the makeup box 1, constructing an automated assembly system of "baseline positioning - step-by-step assembly - cyclic detection - closed-loop maintenance" to achieve precise docking of each component and efficient operation throughout the entire process. From the perspective of component assembly relationships, the mounting base 101 serves as the core base, forming a threaded connection with the rotary transmission sleeve 102 via an external threaded shaft, providing stable support for subsequent component assembly. The rotary transmission sleeve 102, functional bearing seat 103, inner sealing disc 104, and inner shell cover 105 are sequentially connected via snap-fit ​​or threaded engagement, ensuring both the assembly stability of each component and clarifying the assembly sequence. From the perspective of the device's operating logic, the assembly machine 2 uses the fixed plate 5 as a fixed reference, driving the sleeve plate 6 to rotate coaxially to achieve cyclic transfer. The fixed seats 7, arranged at equal angles, can simultaneously carry multiple parts to be assembled, improving assembly efficiency. Five feeding components 3 correspond one-to-one with each makeup box 1 component, ensuring feeding accuracy. The unloading and transfer components 4 realize the precise guidance and insertion of the parts. The positioning, tightening, detection, unloading, and maintenance components arranged along the processing path form a complete assembly process. Through the closed-loop design of "positioning-assembly-detection-maintenance," it ensures that each step of assembly meets the accuracy requirements, ultimately achieving automated and standardized assembly of the finished makeup box 1. The entire system combines the precise coordination of mechanical structures with automated control. The core is to solve the pain points of low efficiency and large errors in manual assembly through process standardization and precise positioning.

[0030] In addition to the conventional benefits of improved assembly efficiency, reduced labor costs, and guaranteed assembly accuracy, this device and system offer more than three unexpected, synergistic advantages. First, the coaxial design of the fixed plate 5 and the drive sleeve 6 not only ensures stability during transport but also unexpectedly achieves "self-calibration of concentricity" in component assembly. When a slight deviation occurs in the threaded connection between the rotary transmission sleeve 102 and the mounting base 101, the coaxial rotation of the drive sleeve 6 can drive the component to fine-tune. Combined with the secondary positioning component 11, this further improves assembly accuracy while reducing component wear. Second, the cleaning and lubrication functions of the multi-functional processing module 14 not only extend the service life of the fixed base 7 and reduce equipment maintenance costs but also prevent residual impurities from affecting subsequent assembly, indirectly improving the finished product qualification rate. This synergizes with the infrared positioning detection component 12; the former reduces assembly risks at the source, while the latter accurately detects defective products, providing double protection for finished product quality. Thirdly, the independent layout and coordinated operation of the five feeding components 3 not only adapt to different specifications of makeup box 1 components, but also realize "material shortage warning linkage". When a feeding component 3 is short of material, the system can automatically pause the corresponding assembly stage to avoid empty or incorrect assembly, while not affecting the feeding preparation of other components, thus improving the stability and fault tolerance of the system operation. Fourthly, the layered design of primary and secondary tightening not only ensures the firmness of the threaded connection, but also unexpectedly reduces stress damage to the components, extending the service life of the makeup box 1. In conjunction with the separation function of the inner sealing plate 104, it ensures the stability of the internal transmission structure and prevents the contents of the makeup from being affected, achieving a dual improvement in equipment assembly quality and product user experience. These benefits work together to form a virtuous cycle of "equipment stability - assembly precision - product quality - convenient maintenance", far exceeding the expected value of conventional assembly devices.

[0031] Example 2, as Figure 3 As shown, the fixed base 7 includes a bottom anti-slip positioning pad 701, a reference positioning groove 702 located at the center of the bottom anti-slip positioning pad 701, side limiting protrusions 703 symmetrically arranged on the inner wall of the reference positioning groove 702, and a central support bushing 704 fixed at the center of the reference positioning groove 702. Specifically, the mounting base 101 is inserted into the central support bushing 704 of the fixed base 7 with its central external thread shaft to achieve axial positioning. The bottom of the mounting base 101 is fitted into the reference positioning groove 702 to achieve planar positioning. The side limiting protrusions 703 limit the circumferential rotation of the mounting base 101. The bottom anti-slip positioning pad 701 improves the assembly stability and completes precise assembly positioning in conjunction with the primary positioning component 8.

[0032] like Figure 4As shown, after the finished makeup box 1 is assembled and removed by the transfer and unloading component 13, the multi-functional processing module 14 performs an integrated cleaning and lubrication operation on the fixing seat 7. The central support bushing 704, as the core support component for the threaded assembly of the mounting base 101 and the rotary transmission sleeve 102, experiences friction between its inner wall and the external threaded shaft of the mounting base 101 and the inner wall of the rotary transmission sleeve 102 during assembly. This friction easily generates residual impurities such as metal shavings and dust. Furthermore, long-term friction can lead to component wear, thus affecting assembly accuracy and operational smoothness. Therefore, cleaning the fixing seat 7 effectively removes residual impurities, preventing them from affecting subsequent assembly accuracy. Lubrication, through the application of lubricating oil, reduces frictional resistance between components, minimizing wear. This ensures both the accuracy of subsequent assembly and smooth operation, while also extending the service life of the fixing seat 7.

[0033] like Figure 4 As shown, specifically, the multi-functional processing module 14 consists of a cleaning component 15 and a lubrication component 16, which work together to clean and lubricate the mounting base 7.

[0034] like Figure 4 As shown, the cleaning assembly 15 includes a fixed workpiece 1501, a first electric telescopic rod 1502, an integrated head 1503, and a high-pressure jet nozzle 1504. The fixed workpiece 1501 is fixedly installed on the fixed plate 5, providing stable support for the entire cleaning assembly 15. The first electric telescopic rod 1502 is fixedly assembled on the fixed workpiece 1501, and the output end of the first electric telescopic rod 1502 is fixedly connected to the integrated head 1503, which can drive the integrated head 1503 to achieve telescopic movement and accurately align with the central support sleeve 704 of the fixed seat 7. The integrated head 1503 is provided with a positioning jaw that matches the shape of the central support bushing 704, which is used to achieve precise positioning when docking with the central support bushing 704, ensuring the targeted nature of the cleaning operation; the inner wall of the positioning jaw is provided with a high-pressure air jet 1504, which is connected to an external air jet through a pipeline, and the air jet direction is towards the inner wall and outer peripheral surface of the central support bushing 704. The high-pressure airflow can quickly remove impurities and debris attached to the surface of the fixed seat 7 and the central support bushing 704 inside it, ensuring the cleaning effect.

[0035] like Figure 4As shown, the lubrication assembly 16, as the core execution component of the multi-functional processing module 14, includes a steering bracket 1601 and a lubrication head 1602. The steering bracket 1601 and the lubrication head 1602 work together to achieve precise lubrication and secondary cleaning of the central support bushing 704. The steering bracket 1601 integrates a control module, as well as an X-axis drive assembly 1603 and a Y-axis drive assembly 1604 connected to the control module. The control module can precisely control the movement of the X-axis and Y-axis drive assemblies 1604, thereby driving the lubrication head 1602 to achieve multi-directional and multi-angle adjustments, ensuring precise alignment between the lubrication head 1602 and the central support bushing 704. The lubrication head 1602 adopts a wrap-around structure design, fitting snugly against the outer surface of the central support bushing 704. It can stably release lubricating oil to achieve uniform lubrication, and also perform secondary cleaning of fine dust and impurities remaining on the surface of the central support bushing 704, further improving the cleaning effect.

[0036] The lubrication assembly 16 achieves multi-dimensional precision operation through the coordinated operation of the steering bracket 1601 and the lubrication head 1602. The core function of the control module integrated on the steering bracket 1601 is to receive system signals and precisely control the X-axis drive assembly 1603 and the Y-axis drive assembly 1604. Through bidirectional drive, the lubrication head 1602 can be flexibly adjusted in multiple directions and angles, ensuring that the lubrication head 1602 can be precisely aligned with the center support bushing 704 in different positions and states. This solves the problem that single-direction adjustment is difficult to adapt to the all-round lubrication of the center support bushing 704.

[0037] The enveloping structure of the lubrication head 1602 is key to achieving the dual functions of "lubrication + secondary cleaning". Its design, which fits the outer surface of the central support bushing 704, allows the lubricating oil to stably and evenly cover the surface of the central support bushing 704 and key friction parts, effectively reducing frictional resistance during assembly. On the other hand, when the enveloping structure is on the surface of the central support bushing 704, it can perform secondary wiping and cleaning of the fine dust and debris remaining after the high-pressure air jet of the cleaning component 15, making up for the inability of high-pressure airflow to remove fine impurities. It complements the cleaning component 15, realizing a closed-loop operation for the maintenance of the fixed seat 7, and ensuring the accuracy of subsequent assembly.

[0038] like Figure 5 , Figure 6 and Figure 7As shown, the lubrication head 1602 further includes an outer sleeve 160201, and a silicone inner sleeve 160202 is fixedly mounted on the inner surface of the outer sleeve 160201. A silicone layer 160203 is integrally formed on the inner surface of the silicone inner sleeve 160202, wherein the thickness of the silicone layer 160203 is less than the thickness of the silicone inner sleeve 160202, and the bottoms of the two are connected by an integral molding process to ensure the integrity and stability of the structure. The silicone layer 160203 has a concave shape in the middle, forming a concave portion 160204 that matches the outer ring size of the central support bushing 704. The inner surface of the concave portion 160204 is designed with a corrugated structure. The structure of the concave portion 160204 is similar to that of an intestinal structure, which can increase the contact area between the silicone layer 160203 and the central support bushing 704, and at the same time facilitate the adhesion and uniform distribution of lubricating oil. The top of the concave portion 160204 is equipped with a lubricating oil release component 17, which is used to release lubricating oil evenly and uniformly to the inner wall of the concave portion 160204, providing a stable oil supply for lubrication operations.

[0039] In addition, a sealed air cavity is formed between the outer ring of the silicone layer 160203 and the inner wall of the silicone inner sleeve 160202. This air cavity is connected to an external air pump through a pipeline. The air pump can adjust the inflation and deflation of the air cavity according to the actual size of the central support bushing 704, thereby driving the silicone layer 160203 to expand or contract. This allows the inner ring of the silicone layer 160203 to fit tightly against the central support bushing 704 of different sizes, improving the versatility and adaptability of the lubrication assembly 16 and ensuring the consistency of lubrication and cleaning effects.

[0040] It is worth noting that the corrugated concave structure of the silicone layer 160203 not only increases the contact area and stores lubricating oil, but also forms a dual function of "scraping and containing" when it fits the central support bushing 704. This deeply cleans the fine debris remaining in the cleaning component 15. The corrugated groove can temporarily contain the debris, preventing it from falling off and contaminating the central support bushing 704 again during cleaning. In conjunction with the fitting function of the air cavity adjustment, it achieves the effect of "more thorough cleaning and more uniform lubrication".

[0041] In addition, the silicone material itself is soft and wear-resistant. The silicone layer 160203 flexibly fits with the central support bushing 704, which not only avoids wear of the central support bushing 704 caused by hard contact, but also polishes the surface of the central support bushing 704 during the lubrication process, reducing friction burrs on the surface of the central support bushing 704. In conjunction with the secondary tightening component 10, it reduces the frictional resistance of the threaded connection during assembly and improves the smoothness of assembly.

[0042] Third, the air filling and defilling adjustment function of the sealed air chamber can not only adapt to different specifications of the central support bushing 704, but also flexibly adjust the bonding force according to the wear degree of the central support bushing 704. The bonding pressure can be appropriately increased in severely worn parts to improve the lubrication and cleaning effect, while avoiding the wear of the silicone layer 160203 caused by excessive bonding. In conjunction with the maintenance function of the multi-functional processing module 14, it can extend the service life of the lubrication head 1602.

[0043] like Figure 7 As shown, secondly, the inner ring surface of the concave portion 160204 of the silicone layer 160203 is coaxially and evenly distributed with annular scrapers 160205 from top to bottom. The annular scrapers 160205 and the silicone layer 160203 are made with an integral molding process, which makes the structure stable and not easy to fall off. When the central support bushing 704 is inserted into the inner ring of the silicone layer 160203, the annular scrapers 160205 can further scrape off the dust and fine impurities remaining on its surface to achieve secondary cleaning. At the same time, after the lubrication operation is completed, the annular scrapers 160205 can scrape off the excess lubricating oil on the surface of the central support bushing 704 to avoid lubricating oil residue affecting subsequent assembly operations and ensure lubrication accuracy.

[0044] like Figure 7 As shown, in addition, the inner surface of the concave portion 160204 of the silicone layer 160203 is provided with arc-shaped scrapers 160206 at equal angles. The arc-shaped scrapers 160206 are integrally formed with the silicone layer 160203, and their curvature is perfectly matched with the curvature of the inner wall of the concave portion 160204. The arc-shaped scrapers 160206 and the annular scrapers 160205 are distributed in a crisscross pattern, dividing the inner circle of the silicone layer 160203 into several rectangular oil storage grooves. The oil storage grooves can temporarily store the lubricating oil, slow down the rate of lubricating oil loss, and ensure that the surface of the central support bushing 704 can be continuously lubricated, further improving the lubrication effect and durability.

[0045] It is worth noting that the crisscrossing distribution of the annular scraper 160205 and the arc-shaped scraper 160206 not only achieves the functions of scraping and oil storage, but also unexpectedly enhances the structural toughness of the silicone layer 160203, avoiding deformation caused by long-term adhesion, compression, expansion and contraction of the silicone layer 160203. In conjunction with the one-piece molding process and the air cavity adjustment function, it extends the service life of the silicone layer 160203 and reduces equipment maintenance costs.

[0046] Secondly, the 160205 annular scraper removes excess lubricating oil, which not only prevents assembly contamination but also guides the scraped excess oil to the rectangular oil storage tank, realizing the recycling of lubricating oil, reducing oil waste, and working in synergy with the oil storage function of the oil storage tank to form an oil cycle of "scraping-recycling-reuse", taking into account both environmental protection and economy.

[0047] like Figure 8 and Figure 9 As shown, specifically, the lubricating oil release component 17, as the core component for oil source regulation of the lubrication head 1602, is coaxially assembled from a limiting disc 1701, a rotating collar 1702, and an upper cover 1703. The bottom of the rotating collar 1702 is sealed and bonded to the top opening of the recessed portion 160204 of the silicone layer 160203, ensuring that lubricating oil does not leak from the connection. The upper surface of the rotating collar 1702 is coaxially fixed to the upper cover 1703, ensuring synchronous movement. The upper cover 1703 has mounting holes for accommodating bearings, and the limiting disc 1701 is embedded inside the bearing, serving as an axial limit and rotation guide, providing support for the stable rotation of the upper cover 1703. The upper cover 1703 rotates in both directions outside the limiting disc 1701 via the drive component 1704 installed inside the outer sleeve 160201, thereby driving the top of the silicone layer 160203 to rotate synchronously. This rotation simulates the principle of compression, causing the flexible material oil reservoir to deform, thereby further squeezing and releasing the lubricating oil stored in the oil reservoir, ensuring that the lubricating oil can evenly cover the outer surface of the central support bushing 704, and improving the uniformity of lubrication.

[0048] like Figure 8 and Figure 9 As shown, the driving component 1704 further adopts a gear transmission structure, mainly composed of a gear ring 170403, a drive motor 170401, and a bevel gear 170402. Its transmission is precise and its operation is stable, effectively ensuring the rotational accuracy and controllable speed of the upper cover 1703. The gear ring 170403 is coaxially fixed to the upper surface of the upper cover 1703 and rotates synchronously with it. The drive motor 170401 is fixedly assembled inside the outer sleeve 160201, providing power output to the driving component 1704. The output end of the drive motor 170401 is fixedly connected to the bevel gear 170402, which meshes with the gear ring 170403 to transmit the power of the drive motor 170401 to the gear ring 170403, thereby driving the gear ring 170403 to rotate the upper cover 1703.

[0049] It is worth noting that the gear transmission structure of the drive component 1704 is precise and the speed is controllable. It can not only ensure the rotational accuracy of the upper cover 1703, but also control the torsion amplitude of the silicone layer 160203 by adjusting the speed, thereby regulating the amount of lubricating oil released. It is compatible with the center support bushing 704 with different wear levels. Together with the fitting function of the air chamber adjustment, it can achieve "oil release on demand", which avoids oil waste and ensures lubrication effect.

[0050] Secondly, when the upper cover 1703 twists and drives the silicone layer 160203 to twist synchronously, it will drive the annular scraper 160205 and the arc-shaped scraper 160206 to rotate together, forming a "twisting scraping" effect, further scraping away the fine impurities remaining on the surface of the central support bushing 704, while allowing the scraped excess lubricating oil to flow more evenly to the oil reservoir. Together with the static scraping of the scraper and the oil storage function of the oil reservoir, it achieves a dual improvement of "dynamic cleaning + oil circulation".

[0051] like Figure 8 and Figure 9 As shown, it should be noted that the bevel gear 170402 is precisely positioned above the gear ring 170403 to ensure the coaxiality and stability of the meshing transmission between the two, avoid problems such as jamming and offset during transmission, and ensure the smoothness and reliability of the lubricating oil release action.

[0052] like Figure 8 and Figure 9 As shown, to achieve the self-cleaning function of the oil reservoir and optimize the control of lubricating oil release, a cylinder 18 is fixedly mounted on the top of the outer sleeve 160201. The output end of the cylinder 18 is coaxially connected to the limiting disc 1701, which can drive the lubricating oil release component 17 to move axially up and down. This displacement action does not interfere with the forward and reverse rotation of the upper cover 1703, ensuring that the lubrication and self-cleaning actions operate independently and in coordination. While the cylinder 18 drives the lubricating oil release component 17 to move up and down, combined with the air pump's inflation of the air chamber, the concave portion 160204 of the silicone layer 160203 in its initial state can be deformed outward. This simultaneously drives the oil reservoir to expand and generate tension. The tension is used to achieve self-cleaning by scraping impurities from the inner wall of the oil reservoir, effectively removing residual dust, debris, and other impurities from the oil reservoir, and preventing the accumulation of impurities from affecting the purity and lubrication effect of the lubricating oil.

[0053] The axial displacement driven by cylinder 18 not only achieves self-cleaning of the oil reservoir, but also drives the lubricating oil release component 17 to move up and down during lubrication operations, allowing the silicone layer 160203 to fully fit with the central support bushing 704. Combined with the scraping action of the scraper, it further improves the uniformity of cleaning and lubrication. In conjunction with the air chamber's inflation and deflation adjustment function, it adapts to central support bushings 704 of different lengths, enhancing the component's adaptability.

[0054] In addition, the self-cleaning function of the oil reservoir and the scraper cleaning function work together to form a dual cleaning system of "dynamic scraping + self-cleaning in the reservoir". This not only avoids the accumulation of impurities, but also reduces the wear of the scraper and extends its service life. In conjunction with the oil release function of the lubricating oil release component 17, it ensures the purity of the lubricating oil and reduces the frictional wear of the central support bushing 704.

[0055] like Figure 8 and Figure 9As shown, the bevel gear 170402 is precisely positioned above the gear ring 170403. This structural design enables effective separation of the rotational lubrication process and the self-cleaning process: when the bevel gear 170402 drives the gear ring 170403 to rotate forward and backward, it mainly completes the squeezing and release of lubricating oil and uniform lubrication; when the cylinder 18 drives the lubricating oil release component 17 to move up and down and cooperates with the air pump to charge, it mainly completes the self-cleaning of the oil reservoir. The two processes do not interfere with each other and can be operated independently or started in concert, improving operating efficiency and reliability.

[0056] like Figure 8 and Figure 9 As shown, a cylindrical oil reservoir 1705 is formed between the upper cover 1703 and the rotating collar 1702, used for temporary storage of lubricating oil to provide a continuous oil source for lubrication operations. A bellows 1707 is embedded inside the upper cover 1703. One end of the bellows 1707 is connected to an external oiling device, and the other end is connected to the cylindrical oil reservoir 1705. The bellows 1707 has good flexibility and deformation capability, which can adapt to the positional changes during the vertical displacement of the lubricating oil release component 17, ensuring the continuity and sealing of the lubricating oil supply channel and preventing lubricating oil leakage. A sponge block 1706 is inserted inside the cylindrical oil reservoir 1705. The bellows 1707 continuously delivers lubricating oil to the sponge block 1706, utilizing the absorbency of the sponge block 1706 to achieve stable storage and slow penetration of the lubricating oil.

[0057] Furthermore, a retractable movable part 1708 is fitted at the bottom opening of the cylindrical oil reservoir 1705. This movable part 1708 adopts an elastic telescopic structure, and its bottom precisely aligns with the top of the central support bushing 704 when inserted. When the central support bushing 704 is inserted into the concave portion 160204 of the silicone layer 160203, its top contacts and compresses the bottom of the movable part 1708, causing the movable part 1708 to expand and contract, thereby intermittently compressing the sponge block 1706 inside the cylindrical oil reservoir 1705. After the sponge block 1706 is compressed, the lubricating oil stored inside is intermittently released and flows along the bottom opening of the cylindrical oil reservoir 1705 to the inner wall of the concave portion 160204 of the silicone layer 160203, achieving uniform lubrication of the inner surface of the concave portion 160204 of the silicone layer 160203, further improving the lubrication effect between the lubrication head 1602 and the central support bushing 704, while ensuring the rational use of lubricating oil and avoiding waste.

[0058] It is worth noting that the adsorption and slow penetration characteristics of the sponge block 1706 can not only stably store lubricating oil, but also filter out tiny impurities in the lubricating oil, preventing impurities from flowing to the surface of the central support bushing 704 with the oil. Together with the self-cleaning function of the oil reservoir and the scraper cleaning function, it forms a triple protection of "filtration-cleaning-lubrication", further ensuring the purity of lubrication and reducing the wear of the central support bushing 704.

[0059] In addition, the oil release synergistically of the sponge block 1706 and the moving part 1708 can automatically adjust the oil release amount according to the insertion frequency of the central support bushing 704. The more frequently the central support bushing 704 is inserted, the more timely the oil release. In coordination with the cyclic operation of the drive sleeve 6, "on-demand grease supply and precise lubrication" can be achieved, which not only avoids oil waste but also ensures continuous lubrication of the central support bushing 704. At the same time, the buffering effect of the sponge block 1706 can prevent the moving part 1708 from making hard contact with the central support bushing 704, protecting the top of the central support bushing 704 from damage.

[0060] like Figure 9 As shown, specifically, the movable part 1708 adopts an elastic telescopic structure design, mainly composed of a limiting sleeve 170801, a connecting rod 170802 and a buffer spring. The components work together to achieve elastic telescopic and pressure transmission, ensuring that the intermittent squeezing action of the sponge block 1706 is precise and controllable. The limiting sleeve 170801 serves as a guide and limiter. Its top is physically fixedly connected to the top of the outer sleeve 160201. The limiting sleeve 170801 is coaxially arranged inside the sponge block 1706 to avoid interference with the sponge block 1706, while providing stable guidance for the telescopic movement of the connecting rod 170802. The connecting rod 170802 can telescopically move along the axial direction of the limiting sleeve 170801. It is connected to the limiting sleeve 170801 by a buffer spring. The buffer spring can provide elastic support for the telescopic movement of the connecting rod 170802 and can also realize automatic reset after compression, ensuring the continuity and stability of the movement of the moving part 1708. The bottom of the connecting rod 170802 is fixedly equipped with a pressure block 170803, which serves as the contact force-bearing component between the moving part 1708 and the central support bushing 704, and is used to transmit the insertion pressure of the central support bushing 704 to the sponge block 1706. The elastic reset function of the buffer spring not only ensures the continuous movement of the moving part 1708, but also buffers the impact force when the center support bushing 704 is inserted, avoiding damage to the center support bushing 704 and the moving part 1708 caused by hard contact. Together with the flexible characteristics of the silicone pressure block 170803, it forms a double buffer protection, extends the service life of the center support bushing 704 and the moving part 1708, and reduces equipment maintenance costs.

[0061] To optimize the force transmission effect, adapt to the structure of the central support bushing 704, and achieve the slow release supply of lubricating oil, the pressure block 170803 is made of silicone material. Silicone material has good flexibility and wear resistance, which can avoid scratching damage to the surface of the central support bushing 704. The pressure block 170803 has an arc-shaped surface on the side near the central support bushing 704. This arc-shaped surface matches the top contour of the central support bushing 704, which can increase the contact area between the two, ensure uniform pressure transmission, and avoid excessive local pressure that could damage the component. Several slow-release grooves are provided on the side of the pressure block 170803 that is fixedly connected to the connecting rod 170802. Each slow-release groove is evenly distributed at equal angles around the central axis of the pressure block 170803. Its function is to allow the lubricating oil to flow slowly through the slow-release grooves when the sponge block 1706 is squeezed to release lubricating oil, thus avoiding a large amount of lubricating oil flowing out instantly and causing waste. At the same time, it ensures that the lubricating oil can flow evenly to the inner wall of the concave portion 160204 of the silicone layer 160203. The slow-release groove's guiding effect not only avoids oil waste but also allows the lubricating oil to be evenly distributed along the groove to the surface of the pressure block 170803. When the central support bushing 704 is inserted, it achieves the dual effect of "contact lubrication + subsequent wetting". Together with the silicone layer 160203 scraper and the oil reservoir, it forms a uniform and durable lubricating layer on the surface of the central support bushing 704, reducing friction loss.

[0062] In addition, the cross-section of the pressure block 170803 is designed as a circular structure, and its external dimensions match the bottom opening size of the cylindrical oil reservoir 1705. This ensures precise alignment between the pressure block 170803 and the bottom opening of the cylindrical oil reservoir 1705, preventing lubricating oil from leaking through gaps. It also ensures that the pressure block 170803 exerts a uniform pressure on the sponge block 1706, further improving the uniformity and stability of lubricating oil release.

[0063] Example 3: Based on the above-mentioned assembly device for the multifunctional makeup box 1, the assembly system of the assembly device includes the following steps: S1: Loading and primary positioning of the reference component; After the system starts, the first loading component 3 automatically loads the makeup box 1 mounting base 101, and the corresponding unloading and transfer component 4 precisely guides and inserts the mounting base 101 into the fixing seat 7 of the drive sleeve 6. The fixing seat 7 achieves triple limiting of planar positioning, axial positioning, and circumferential anti-rotation for the mounting base 101 through the bottom anti-slip positioning pad 701, the central reference positioning groove 702, the side limiting protrusion 703, and the central support bushing 704; the primary positioning component 8 completes the final accuracy calibration, and the coaxial design of the fixing plate 5 and the drive sleeve 6 provides a stable concentricity guarantee for the subsequent component transfer and establishes the reference accuracy of the overall assembly.

[0064] S2: Layered assembly and secondary verification of transmission components; The drive sleeve 6 rotates at a constant speed around the fixed plate 5, transferring the reference component to the second loading station, completing the automatic loading of the rotary transmission sleeve 102. The unloading and transfer component 4 precisely aligns the transmission sleeve with the external threaded shaft of the mounting base 101. The system sequentially activates the primary tightening component 9 and the secondary tightening component 10, completing the threaded connection through layered tightening to avoid stress damage to the component caused by a single tightening. After assembly, the secondary positioning component 11 performs precision testing on the coaxiality and tightness of the rotary transmission sleeve 102. Defective products are automatically rejected, and qualified products proceed to the next assembly stage.

[0065] S3: The main body of the makeup box is assembled in steps; After the accuracy verification is passed, the drive plate 6 is sequentially transferred to the third, fourth, and fifth loading stations to complete the automatic loading and assembly of the functional support 103, inner sealing plate 104, and inner shell 105, respectively. The functional support 103 is engaged with the rotary transmission sleeve 102 to receive power. The inner sealing plate 104 is engaged with the top of the support to separate the internal transmission space from the upper makeup cavity. The inner shell 105 encapsulates all internal components to complete the outer shell sealing. All components are precisely connected according to the process sequence through snap-fit ​​and threaded engagement to form a complete finished makeup box 1.

[0066] S4: Finished product inspection, automatic unloading and workstation maintenance; The finished makeup box 1 is transferred to the infrared positioning and detection component 12. The system automatically detects the assembly integrity, dimensional accuracy, and component fit clearance, and selects qualified finished products. Qualified products are clamped and transferred by the transfer and unloading component 13 to the designated unloading position, completing the finished product output.

[0067] After unloading, the multi-functional processing module 14 initiates integrated cleaning and lubrication operations: the cleaning component 15 removes metal debris and dust from the central support bushing 704 of the fixed seat 7 using high-pressure air jets; the lubrication component 16, through the wrap-around lubrication head 1602, adjusts the air chamber to fit the size of the central support bushing 704, and the annular and arc-shaped scrapers 160206 complete secondary cleaning and oil storage; the lubricating oil release component 17 releases oil as needed, and the cylinder 18 drives the self-cleaning of the oil storage tank. After maintenance, the drive sleeve 6 resets, and the system enters the next assembly cycle, achieving continuous automated operation throughout the entire process.

[0068] Working principle: First, after the system starts, it enters the stage of loading and positioning the reference components. The first loading component 3 conveys the makeup box 1 mounting base 101, and the unloading and transfer component 4 accurately inserts it into the fixed seat 7 of the drive sleeve 6. The fixed seat 7 completes the triple limiting of the mounting base 101 in plane, axis, and circumference through the bottom anti-slip positioning pad 701, the reference positioning groove 702, the side limiting protrusion 703 and the central support bushing 704. The first positioning component 8 completes the accuracy calibration. The coaxial structure of the fixed plate 5 and the drive sleeve 6 lays a stable concentricity reference for subsequent transfer, ensuring that the reference components are not offset or rotated.

[0069] Then, the drive sleeve 6 drives the fixed seat 7 to rotate to the second station, and the corresponding feeding component 3 supplies the rotary transmission sleeve 102. The unloading and transfer component 4 accurately connects it to the external threaded shaft of the mounting base 101. Subsequently, the primary tightening component 9 and the secondary tightening component 10 apply rotational power in layers to avoid stress damage caused by single tightening. The secondary positioning component 11 detects the coaxiality and tightness of the rotary transmission sleeve 102 in real time and automatically rejects unqualified products. Qualified products smoothly enter the next assembly process with the drive sleeve 6.

[0070] Next, the drive plate 6 is sequentially transferred to the third to fifth workstations to complete the automated loading and assembly of the functional support 103, inner sealing plate 104, and inner shell cover 105. Each component is precisely connected according to the process sequence through snap-fit ​​and threaded connection. The inner sealing plate 104 separates the transmission space from the makeup cavity, and the inner shell cover 105 wraps the internal components to complete the outer shell encapsulation. The complete makeup box 1 is gradually assembled. Each process works together to avoid misalignment and omissions.

[0071] Subsequently, the finished makeup box 1 is transferred to the infrared positioning and detection component 12 station. This component comprehensively verifies the assembly accuracy, integrity and component fit gap of the finished product, accurately selects qualified finished products, and the qualified products are clamped and transferred by the transfer and unloading component 13 to the designated unloading position to complete the automated finished product output.

[0072] Finally, after the material is unloaded, the automatic maintenance stage begins. The multi-functional processing module 14 starts integrated operation. The cleaning component 15 drives the integrated head 1503 to connect with the central support bushing 704 via the electric telescopic rod. The high-pressure jet nozzle 1504 sprays high-pressure airflow to remove metal debris and dust from the central support bushing 704. The steering bracket 1601 of the lubrication component 16 adjusts the lubrication head 1602 for precise alignment. The sealed air chamber is filled and deflated, causing the silicone layer 160203 to expand and contract to fit the outer wall of the central support bushing 704. The annular and arc-shaped scrapers 160206 complete the process. The system performs secondary cleaning and forms an oil storage tank. The drive motor 170401, through the meshing of the bevel gear 170402 and the gear ring 170403, drives the silicone layer 160203 to twist and squeeze the oil storage tank to release oil evenly. The cylinder 18 drives the lubricating oil release part 17 to move up and down, and cooperates with the air chamber to inflate the oil storage tank to achieve self-cleaning. The moving part 1708 is squeezed by the central support bushing 704 to intermittently supply oil to ensure uniform lubrication. After maintenance, the system is reset, and the drive sleeve 6 enters the next assembly cycle, continuously realizing the fully automated, continuous, and high-precision assembly operation of the makeup box 1.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
