[0047] In one embodiment, such as Figure 1 and Figure 2 As shown, a lip gloss assembly machine is provided, including a rotating worktable 310, a tube cap assembly module, a rod core assembly module, a burr assembly module, and a detection module; the tube cap assembly module, rod core assembly module, burr assembly module, and detection module are arranged sequentially on the rotating worktable 310 according to the process flow.

[0048] Multiple pipe cover mounting fixtures are provided along the edge of the rotating worktable 310;

[0049] The pipe cap assembly module is used to place the pipe cap into the pipe cap mounting fixture and spray adhesive inside the pipe cap; the pipe cap with adhesive sprayed on is transferred to the workstation in the area where the rod core assembly module is located via the rotating worktable 310.

[0050] The rod core assembly module is used to put the rod core into the tube cap to form a tube cap-rod core assembly; then the tube cap-rod core assembly is transferred to the workstation in the area where the burr assembly module is located by rotating the work plate 310.

[0051] The burr assembly module is used to insert and fix the burrs into the rod core to form a tube cap-rod core-burr assembly; then, the tube cap-rod core-burr assembly is transferred to the workstation in the area where the detection module is located by rotating the work plate 310; the burr assembly module includes a burr feeding mechanism; the burr feeding mechanism is adapted to various specifications of burrs.

[0052] The detection module is used to check the firmness between the rod core and the burr.

[0053] Understandably, the lip gloss assembly machine provided in this embodiment is an automated device used to assemble a tube cap-rod-feather assembly consisting of a tube cap, a rod, and a burr. The lip gloss assembly machine includes a rotating worktable 310, a tube cap assembly module, a rod assembly module, a burr assembly module, and a detection module. The tube cap assembly module, rod assembly module, burr assembly module, and detection module are sequentially arranged on the rotating worktable 310 according to the process flow. These modules can be arranged in a clockwise direction or a counterclockwise direction (e.g., ...). Figure 1 ).

[0054] The rotating worktable 310 can be a turntable driven by a cam divider. The cam divider is a precision mechanism that converts continuous motor rotation into precise intermittent rotation. Multiple cap mounting fixtures are arranged along the edge of the rotating worktable 310. These fixtures are evenly distributed along the edge area of ​​the rotating worktable 310, serving to position the caps. The cap mounting fixtures are detachable, facilitating quick replacement or maintenance, improving assembly efficiency and flexibility for different cap sizes. When the lip gloss assembly machine starts working, the cap assembly module handles cap feeding and adhesive spraying. The cap assembly module includes at least a cap feeding mechanism 101 for feeding the caps and a spraying mechanism for applying the adhesive. The adhesive can be hot melt glue or cold glue. After the adhesive is applied, the caps are transferred via the rotating worktable 310 to the workstation in the area where the core assembly module is located.

[0055] The core assembly module is used to insert the core into the tube cap and hold it for a certain period of time to ensure the adhesive has initially cured, achieving a firm bond between the core and the tube cap, forming a tube cap-core assembly. The core consists of a core fixing part and a pen barrel. Then, the tube cap-core assembly is transferred to the workstation in the area where the nib assembly module is located by rotating the worktable 310.

[0056] The burr assembly module is used to fix the burr to the end of the pen barrel away from the core fixing part. After the burr assembly is completed, a tube cap-core-burr assembly is formed. Then, the tube cap-core-burr assembly is transferred to the workstation in the area where the detection module is located by rotating the worktable 310. The burr assembly module includes a burr feeding mechanism. The burr feeding mechanism can accommodate various specifications of burrs, such as burr lengths of 3~8mm.

[0057] The testing module is used to check the tightness between the core and the burr. In some examples, the testing module can use a pull-out test to test the tightness between the core and the burr. If the burr is not pulled out, it indicates that the installation is secure and the assembly is of acceptable quality; otherwise, it is considered unacceptable. Different burr specifications correspond to different pull-out force standards.

[0058] The lip gloss assembly machine provided in this embodiment achieves efficient and precise assembly of various components of the lip gloss product by integrating an automated assembly module for the tube cap, rod core, and burr. The modules are arranged sequentially along the rotating worktable 310, and together with the rotation of the tube cap mounting fixture, a continuous assembly line operation is formed, which significantly improves production efficiency. By setting up a detection module, the reliability and quality stability of the product assembly are ensured.

[0059] Optionally, the pipe cap assembly module is provided with a pipe cap feeding mechanism 101, a pipe cap transfer mechanism, a pipe cap leveling mechanism 102, and a glue spraying mechanism 103;

[0060] The pipe cap feeding mechanism 101 is used to transport the pipe cap to the pipe cap transfer station;

[0061] The pipe cap transfer mechanism is used to transfer the pipe cap from the pipe cap transfer station to the pipe cap installation fixture; then, by rotating the work plate 310, the pipe cap is transferred to the first leveling station.

[0062] The pipe cap flattening mechanism 102 is used to flatten the pipe caps that have been transferred to the pipe cap flattening station; then the pipe caps are transferred to the glue spraying station by rotating the work plate 310.

[0063] The glue spraying mechanism 103 is used to spray glue onto the pipe caps that are transferred to the glue spraying station, so that the adhesive adheres to the inside of the pipe caps; then the pipe caps are transferred to the rod core assembly station by rotating the work plate 310.

[0064] Understandably, the pipe cap assembly module includes a pipe cap feeding mechanism 101, a pipe cap transfer mechanism, a pipe cap leveling mechanism 102, and a glue spraying mechanism 103. The pipe cap feeding mechanism 101 may include a vibratory feeder and a track orientation system. The pipe caps are arranged in a preset orientation (e.g., opening upwards) by the vibratory feeder and transported to the pipe cap transfer station via a linear track. A cylinder-driven stop bar is provided at the end of the track to ensure that the pipe caps stop one by one.

[0065] The pipe cap transfer mechanism is used to precisely grip and place the pipe cap from the transfer station onto the pipe cap mounting fixture on the rotating worktable 310. The pipe cap transfer mechanism can be driven by multiple cylinders to achieve horizontal and vertical movement of the pipe cap. After the pipe cap is transferred to the pipe cap mounting fixture, the rotating worktable 310 rotates counterclockwise, transferring the pipe cap to the first leveling station.

[0066] The pipe cap flattening mechanism 102 is used to flatten the pipe cap placed in the pipe cap mounting fixture, ensuring that the pipe cap opening is flat, facilitating subsequent core insertion and even glue application. The pipe cap flattening mechanism 102 includes a pressing cylinder bracket with a first pressing cylinder mounted on it. A connecting seat is provided on the cylinder rod of the first pressing cylinder, and a guide hole is provided on the connecting seat, through which a guide rod passes. A flattening head matching the shape of the pipe cap opening is installed at the bottom end of the guide rod. The flattening head is made of wear-resistant silicone or engineering plastic to avoid scratching the surface of the pipe cap. After flattening the pipe cap, the pipe cap is transferred to the glue application station by rotating the worktable 310.

[0067] The adhesive spraying mechanism 103 is used to uniformly spray a metered amount of adhesive onto the inner wall of the tube cap. The adhesive spraying mechanism 103 can be connected to a precision dispensing valve via a micro-dispensing pump, and the adhesive quantity is controlled by a CNC system. The dispensing valve has a back-suction function to prevent the adhesive from solidifying. Simultaneously, a waste adhesive collection tank is installed below the nozzle, and a cleaning program is periodically initiated to clean the nozzle and prevent clogging. After the adhesive is sprayed onto the tube cap, the tube cap is transferred to the rod core assembly station via a rotating worktable 310.

[0068] In this embodiment, the tube cap assembly module achieves automated processing and pre-assembly of tube caps through the orderly connection of feeding, transfer, leveling, and glue spraying processes, thereby improving assembly accuracy and efficiency. The tube cap transfer mechanism works in coordination with the rotating worktable 310 to ensure that the tube caps are stably and accurately transferred to each workstation. The tube cap leveling mechanism flattens the tube caps to ensure their shape consistency, providing a reliable foundation for subsequent assembly. The glue spraying mechanism 103 precisely sprays adhesive inside the tube caps to ensure a firm bond between the rod core and the tube cap, thereby improving the product yield.

[0069] Optionally, the pipe cap assembly module is also provided with a first positioning detector 104;

[0070] The first positioning detector 104 is used to detect whether a pipe cap is loaded at the glue spraying station.

[0071] Understandably, the pipe cap assembly module is also equipped with a first positioning detector 104. The first positioning detector 104 can be a photoelectric sensor, located near the glue spraying station, to detect whether a pipe cap is loaded at the glue spraying station. If a pipe cap is detected at the glue spraying station, the glue spraying operation can be performed normally; if no pipe cap is detected, an error reminder is issued.

[0072] This embodiment, by setting a first positioning detector 104, can monitor in real time whether the tube cap is in place at the glue spraying station, avoid missing or empty spraying, and ensure the stability and reliability of the glue spraying process.

[0073] Optionally, the core assembly module includes a core feeding mechanism 202, a core feeding gripper 201, and a clamping mechanism 203;

[0074] The rod core feeding mechanism 202 is used to transport the rod core to the rod core transfer station;

[0075] The rod core feeding gripper 201 is used to grip the rod core from the rod core transfer station, place the rod core into the tube cap at the rod core assembly station to form a tube cap-rod core assembly; then the tube cap-rod core assembly is transferred to the rod core pressing station by rotating the work plate 310.

[0076] The clamping mechanism 203 is used to clamp the tube cap-rod core assembly that has been transferred to the rod core clamping station, so that the bottom surface of the rod core is in contact with the inner bottom surface of the tube cap; then the tube cap-rod core assembly is transferred to the rough head assembly station by rotating the work plate 310.

[0077] Understandably, the core assembly module includes a core feeding mechanism 202, a core feeding gripper 201, and a clamping mechanism 203. The function of the core assembly module is to accurately grip the core, insert it into the tube cap that has been coated with adhesive, and ensure that the bottom of the core is fully fitted and firmly fixed to the inner bottom surface of the tube cap.

[0078] The rod core feeding mechanism 202 is used to orderly and directionally transport the rod cores to the designated rod core transfer station, ensuring that the rod core feeding gripper 201 can reliably grasp them. In some examples, the rod core feeding mechanism 202 is equipped with a vibratory feeder and a conveyor track. The rod cores are automatically sorted and oriented by the vibratory feeder. The neatly arranged rod cores then enter the conveyor track and are transported to the rod core transfer station. A cylinder-driven stop mechanism is provided at the end of the track to ensure that only one rod core remains at the transfer station at a time.

[0079] The rod core feeding gripper 201 is used to precisely grasp the rod core from the transfer station and vertically and stably insert it into the tube cap located in the tube cap mounting fixture to form a tube cap-rod assembly. The rod core feeding gripper 201 includes a horizontal linear module and a vertical lifting cylinder (or electric slide). The horizontal linear module is responsible for moving the gripper from the rod core transfer station to directly above the tube cap. The vertical lifting cylinder controls the up-and-down movement of the gripper. Then, the tube cap-rod assembly is transferred to the rod core clamping station by rotating the worktable 310.

[0080] The clamping mechanism 203 applies a controllable axial pressure to the inserted rod core, ensuring complete contact between the bottom of the rod core and the inner bottom surface of the tube cap, eliminating air between them, and allowing the adhesive to be evenly distributed and form a good initial bond. The clamping mechanism 203 includes a bracket on which a clamping cylinder (or servo electric cylinder) is mounted. The piston rod end of the cylinder is connected to a pressure head that matches the shape of the rod core tip. The clamping force and insertion depth can be precisely controlled by adjusting the pressure of the pneumatic component or setting the parameters of the servo electric cylinder. A limit switch or position sensor ensures that the pressure head is pressed down to a predetermined position, i.e., the rod core is compacted in place. Then, the tube cap-rod core assembly is transferred to the roughing head assembly station by rotating the worktable 310.

[0081] In this embodiment, the rod core assembly module achieves precise insertion and reliable fixation of the rod core within the tube cap through the coordinated operation of feeding, clamping, and pressing. The rod core feeding gripper 201 ensures that the rod core is stably placed into the tube cap, forming a tube cap-rod core assembly, thus improving assembly accuracy. The pressing mechanism 203 performs secondary pressing on the assembly, ensuring that the bottom surface of the rod core completely fits against the inner bottom surface of the tube cap, enhancing the connection strength. Each process automatically flows with the rotating worktable 310, improving overall assembly efficiency and automation.

[0082] Optionally, the core assembly module is also provided with a second positioning detector 204;

[0083] The second position detector 204 is used to detect whether a tube cap is installed at the core assembly station.

[0084] Understandably, the core assembly module also includes a second positioning detector 204. This second positioning detector 204 can be a photoelectric sensor, located near the core assembly station, to detect whether a tube cap is installed at the core assembly station. If a tube cap is detected at the core assembly station, the core insertion operation can be performed normally; if no tube cap is detected, an error message is issued.

[0085] This embodiment, by setting a second positioning detector 204, can monitor in real time whether the tube cap is in place at the rod core assembly station, avoiding the rod core being directly inserted into the tube cap installation fixture, thus ensuring the reliability of the assembly process.

[0086] Optionally, the burr assembly module includes a cam insert burr mechanism 302, a burr platform, a burr flattening mechanism 303, a loading and unloading mechanism 304, a burr feeding gripper 305, a burr secondary assembly mechanism 306, a hot air blowing group 307, and a burr marking mechanism 308; the burr feeding mechanism includes a flexible feeding robot 301.

[0087] The flexible feeding robot 301 is used to sort out the burrs and then transfer them to the burr transfer station.

[0088] The cam-type burr insertion mechanism 302 is used to insert the burr that has been transferred to the burr transfer station into the burr insertion hole on the burr carrier; and then the burr is transferred to the burr flattening station via the burr carrier.

[0089] The burr flattening mechanism 303 is used to flatten the burrs; then the burrs are transferred to the burr loading and unloading station via the burr carrier.

[0090] The picking and loading mechanism 304 is used to pick up the burr from the burr picking and loading station and insert the lower end of the burr into the rod core located at the burr assembly station.

[0091] The feed gripper 305 is used to clamp the upper end of the rod core into which the feed head is inserted, so that the tube opening at the upper end of the rod core is flattened and the feed head is initially fixed to form a tube cap-rod core-feather head assembly; then the tube cap-rod core-feather head assembly is transferred to the secondary assembly station by rotating the work plate 310.

[0092] The secondary assembly mechanism 306 is used to sort the burrs transferred to the secondary assembly station; then, the tube cap-rod core-burr assembly is transferred to the rod head heating station by rotating the work plate 310.

[0093] The hot air blowing unit 307 is used to heat the upper end of the rod core in the tube cap-rod core-finishing assembly that is transferred to the rod head heating station; then the tube cap-rod core-finishing assembly is transferred to the finishing station by rotating the work plate 310.

[0094] The burr marking mechanism 308 is used to mark the upper end of the rod core in the pipe cap-rod core-burr assembly that is transferred to the burr marking station; then the pipe cap-rod core-burr assembly is transferred to the test station by rotating the work plate 310.

[0095] Understandably, the brush head assembly module includes a flexible feeding robot 301, a cam-mounted brush head mechanism 302, a brush head carrier, a brush head leveling mechanism 303, a picking and loading mechanism 304, a brush head feeding gripper 305, a brush head secondary assembly mechanism 306, a hot air blowing unit 307, and a brush head marking mechanism 308. The brush head assembly module is used to accurately and securely install the brush heads onto the rod core that has been inserted into the tube cap, ensuring that the brush head does not easily fall off during use and has a neat appearance. The brush head feeding mechanism includes the flexible feeding robot 301.

[0096] The flexible loading robot 301 is used to gently and precisely organize scattered and easily damaged burrs. It then uses pneumatic grippers or vacuum suction cups to accurately pick up the burrs in the correct orientation and transfer them to a designated burr transfer station. The flexible loading robot 301 is equipped with replaceable vacuum suction cups to accommodate various burr sizes, such as 3-8mm burrs. The flexible loading robot 301 also features a vision recognition unit that automatically identifies the orientation of burrs of different sizes, thereby organizing and transferring them to the burr transfer station.

[0097] The cam-driven burr insertion mechanism 302 uses a servo motor to drive a precision cam divider, which in turn drives a set of insertion pins to perform intermittent vertical insertion and extraction movements. As the mechanism descends, the insertion pins press the burrs received from the burr transfer station into the corresponding insertion holes on the burr carrier. The burr carrier can be a turntable with multiple insertion holes machined to match the shape of the burrs. The burr carrier can be driven by the cam divider, advancing one station in each work cycle. The cam-driven burr insertion mechanism 302 is adjustable to precisely control the insertion depth and position, adapting to different product specifications and improving assembly accuracy and efficiency.

[0098] The bristle flattening mechanism 303 is used to smooth and flatten the bristles of the brush head inserted into the carrier's insertion hole, ensuring that the bristles are neat and free of skewing, facilitating stable gripping by the subsequent robotic arm, and guaranteeing an aesthetically pleasing final product. The bristle flattening mechanism 303 includes a pressure plate driven by a cylinder or servo electric cylinder. As the pressure plate descends, its surface contacts the tip of the brush on the bristle carrier, applying uniform pressure to smooth any bristles that may be sticking up. Then, the bristles are transferred to the bristle loading / unloading station via the bristle carrier. The bristle flattening mechanism 303 has an adaptive function, automatically adjusting the pressure or stroke according to the bristle height to ensure consistent flattening results, improving product quality and stability.

[0099] The loading and unloading mechanism 304 is used to pick up the prepared burrs from the burr carrier and precisely insert them into the rod core that has been transferred to the burr assembly station. The loading and unloading mechanism 304 is replaceable to easily adapt to different specifications of burrs, improving the versatility and changeover efficiency of the burr assembly module.

[0100] The feed gripper 305 is used to clamp the upper end of the rod core into which the feed head is inserted, flattening the tube opening at the upper end of the rod core and initially fixing the feed head to form a tube cap-rod core-feather head assembly. The feed gripper 305 uses flat or cavity-shaped jaws to clamp the upper tube opening of the rod core after the feed head is inserted. Through precisely controlled clamping force, the plastic tube opening at the upper end of the rod core undergoes slight plastic deformation (flattening), thus initially securing the root of the feed head like a snap-fit, forming a preliminary fixation. Then, the tube cap-rod core-feather head assembly is transferred to the secondary assembly station by rotating the worktable 310. The feed gripper 305 is adjustable to accommodate feed heads of different sizes or shapes, ensuring precise clamping and stable feeding.

[0101] The secondary assembly mechanism 306 is used to further refine and tighten the bristles that have been initially inserted into the rod core, ensuring that the bristles are fully in place and in a correct posture, eliminating any minor deviations that may have occurred during the initial fixing. The secondary assembly mechanism 306 gently combs the bristles of the bristles while applying additional axial pressure to ensure the bristle ends are neat. Then, the tube cap-rod core-bristle assembly is transferred to the rod head heating station via the rotating worktable 310.

[0102] The hot air blower assembly 307 is used to heat the upper end of the rod core in the tube cap-rod core-burr assembly, which is transferred to the rod head heating station. Opposing hot air guns can be used here to improve heating efficiency. The hot air guns provide localized and controlled heating of the upper end of the rod core. The hot air blower assembly 307 has adjustable temperature and blowing time. The temperature and blowing time of the hot air are precisely controlled by a PLC to soften the plastic at the rod core end to an optimal plastic state without melting or damaging the burr. In one example, the heating temperature range of the hot air blower assembly 307 includes 50°C to 180°C, and the blowing time can be 1 second to 3 seconds. The tube cap-rod core-burr assembly is then transferred to the burr marking station by rotating the work tray 310.

[0103] The burr marking mechanism 308 is used to mark the upper end of the rod core in the tube cap-rod core-burr assembly that has been transferred to the burr marking station. The burr marking mechanism 308 employs a servo motor to drive one or more marking needles at high speed to impact the heated and softened rod core wall. The marking needles can move simultaneously or sequentially from multiple points on the side or circumference of the rod core, causing the rod core wall to partially indent and deform inward, forming mechanical locking points that firmly hold the burr root in place, preventing it from being pulled out during use. Next, the tube cap-rod core-burr assembly is transferred to the testing station by rotating the worktable 310. The burr marking mechanism 308 is replaceable, facilitating adaptation to different marking positions or burr specifications, improving the flexibility and processing consistency of the burr assembly module.

[0104] In this embodiment, the flexible feeding robot 301 and the cam insertion mechanism 302 work together to achieve automatic sorting, precise insertion and efficient circulation of the burrs, improving the stability of feeding and positioning. The picking mechanism 304 and the burr feeding gripper 305 work together to complete the insertion and initial fixation of the burrs. Then, the burr secondary combination mechanism 306 sorts them, the hot air group 307 heats and softens them, and the burr dotting mechanism 308 seals them to ensure that the connection between the burrs and the rod core is firm and reliable.

[0105] Optionally, the burr assembly module is also provided with a third positioning detector 309;

[0106] The third positioning detector 309 is used to detect whether there are burrs loaded on the burr flattening station.

[0107] Understandably, the burr assembly module is also equipped with a third positioning detector 309. The third positioning detector 309 can be a photoelectric sensor, located near the burr leveling station, to detect whether a burr is loaded at the burr leveling station. If a burr is detected at the burr leveling station, the burr leveling operation can be performed normally; if no burr is detected, an error reminder is issued.

[0108] This embodiment, by setting a third positioning detector 309, can detect in real time whether there are any rough parts in the leveling station, avoiding the leveling mechanism from idling or subsequent processes from being misoperated due to missing parts, thus ensuring the continuity and reliability of the assembly process.

[0109] Optionally, the burr assembly module is also provided with a fourth position detector 311;

[0110] The fourth positioning detector 311 is used to detect whether there are loose parts loaded on the secondary assembly station.

[0111] Understandably, the burr assembly module is also equipped with a fourth positioning detector 311. This fourth positioning detector 311 can be a photoelectric sensor, located near the secondary assembly station, to detect whether burrs are loaded at the secondary assembly station. If burrs are detected at the secondary assembly station, the burr sorting operation can be performed normally; if no burr is detected, an error alert is issued.

[0112] This embodiment, by setting a fourth positioning detector 311, can confirm the presence status of the burrs on the secondary assembly station in real time, preventing the assembly mechanism from being idle or damaged due to missing workpieces, and ensuring the accurate execution of subsequent finishing processes.

[0113] Optionally, the detection module includes a tensile testing gripper 402 and a burr tensile testing mechanism 401;

[0114] Tensile testing gripper 402 is used to clamp the rod core at the testing station;

[0115] The lint pull tester 401 is used to apply an upward pull force to the lint in order to evaluate the lint's pulling force.

[0116] Understandably, the testing module includes a tensile testing gripper 402 and a burr tensile testing mechanism 401. The tensile testing gripper 402 is used to clamp the rod core at the testing station. The tensile testing gripper 402 can be driven by a pneumatic cylinder to move its gripping arm above the rod core fixing part and abut against it. The burr tensile testing mechanism 401 is used to apply an upward pulling force to the burr to evaluate its pulling force. The burr tensile testing mechanism 401 clamps the burr in a controllable manner and applies a vertically upward pulling force to it, while simultaneously and accurately measuring the magnitude of this pulling force in real time until a preset force value is reached. If the burr is not pulled out, it indicates that the burr's pulling force is qualified; otherwise, the burr's pulling force is unqualified.

[0117] In this embodiment, the tensile testing gripper 402 works in conjunction with the burr tensile testing mechanism 401 to apply a quantitative tensile force to the assembled burr, realistically simulating the stress conditions during use, effectively evaluating its connection pulling force; ensuring the reliability of product quality, timely removing defective products, and improving the overall yield rate.

[0118] Optionally, the lip gloss assembly machine also includes an output module, which includes a finished product conveying mechanism 501;

[0119] The finished product conveying mechanism 501 is used to transport the inspected tube cap-rod core-finisher assembly to the designated finished product storage area.

[0120] Understandably, the output module is used to automatically transport the qualified finished products (pipe cap-rod core-burr assembly) to a designated area. The finished product conveying mechanism 501 is used to receive the pipe cap-rod core-burr assembly that has passed the firmness test from the testing station and transport it smoothly and orderly to the designated finished product storage area. Pipe cap-rod core-burr assemblies that fail the firmness test are sent to the defective product area and are either scrapped or reprocessed.

[0121] In this embodiment, by setting up a finished product conveying mechanism 501, qualified tube cap-rod core-finisher assembly can be automatically conveyed to the designated finished product area, realizing continuous and automated product off-line production.

[0122] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
