Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to a bottle cap assembly machine. Background Technology

[0002] Bottles, also known as containers, are one of the most common types of containers in the modern packaging industry. Their basic structure consists of two parts: the bottle body and the cap. Most bottle caps for general purposes have simple structures and can be mass-produced quickly through a one-time injection molding process, resulting in low manufacturing costs and high efficiency. However, with the increasing demands of the consumer market for packaging functionality, more and more bottle caps with complex structures and special properties have emerged, such as caps with anti-counterfeiting, anti-theft, quantitative extrusion, resealable, and child safety protection functions. These functional caps consist of two or more components. Currently, many packaging companies in China still rely mainly on manual assembly of bottle caps. Operators use manual or semi-automatic equipment to align, press, and inspect components. This assembly method is not only labor-intensive and requires a high level of employee skill, but it is also prone to poor product consistency and increased defect rates due to fatigue and other factors. Furthermore, manual assembly has a limited pace, resulting in low overall production efficiency. Utility Model Content

[0011] The feeding mechanism of this invention transports two types of bottle cap assemblies to their corresponding loading stations. A first component vibratory feeder transports the first bottle cap assembly to the first loading mechanism, and a second component vibratory feeder transports the second bottle cap assembly to the second loading mechanism. A guiding component is used for material transport and temporary storage. During operation, the loading robot of the first loading mechanism picks up the first bottle cap assembly and transfers it to the fixed fixture on the rotary table.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] This utility model provides a bottle cap assembly machine, including a frame 1 and a feeding mechanism 2. The frame 1 is fixedly mounted with a worktable 3. The feeding mechanism 2 includes a first component vibrating plate 4 and a second component vibrating plate 5. The worktable 3 is fixedly mounted with a rotating mechanism 6, a first feeding mechanism 7, a second feeding mechanism 8, a pressing mechanism 9, and a discharging mechanism 10. The rotating mechanism 6 includes a rotating drive device 11 and a rotating table 12. The rotating table 12 is fixedly mounted with a fixing fixture 13. The first feeding mechanism 7 and the second feeding mechanism 8 both include a guiding component 14 and a feeding robot 15. The pressing mechanism 9 includes a first support 16, an upper cylinder 17, and a lower cylinder 18. The first support 16 is fixedly mounted with the upper cylinder 17. The driving end of the upper cylinder 17 is fixedly mounted with a pressing block 19. The driving end of the lower cylinder 18 is fixedly mounted with a top column 20. The loading robot 15 includes a fixed frame 21, on which an X-axis cylinder 22 is fixedly mounted. An X-axis moving stage 24 is movably mounted on the fixed frame 21 via an X-axis slide rail 23. The drive end of the X-axis cylinder 22 is fixedly connected to the X-axis moving stage 24. A Z-axis cylinder 25 is fixedly mounted on the X-axis moving stage 24. A Z-axis moving stage 27 is movably mounted on the X-axis moving stage 24 via a Z-axis slide rail 26. The drive end of the Z-axis cylinder 25 is fixedly connected to the Z-axis moving stage 27. A clamping cylinder 28 is fixedly mounted on the Z-axis moving stage 27. A chuck 29 is fixedly mounted on the drive end of the clamping cylinder 28. The feeding mechanism 10 includes an ejection assembly 30 and a guiding assembly 31. The ejection assembly 30 includes a second bracket 32, on which an ejection cylinder 33 is fixedly mounted. A guide post 35 is movably mounted on the second bracket 32 ​​via a flange structure 34. The driving end of the ejection cylinder 33 is fixedly connected to the guide post 35. The guiding assembly 31 includes a third bracket 36, on which an arc-shaped baffle 37 and a guide plate 38 are fixedly mounted. A fourth bracket 39 is fixedly mounted on the worktable 3, and a first laser detector 40 is fixedly mounted on the fourth bracket 39. The guiding assembly 14 includes a vibrator 41 and a guiding channel 42. The vibrator 41 is fixedly mounted on the guiding channel 42, and a material placement component 43 is fixedly mounted at one end of the guiding channel 42. A second laser detector 44 is fixedly mounted on the material placement component 43.

[0021] Through the above technical solution, the feeding mechanism 2 of this utility model conveys the two bottle cap assemblies to the corresponding loading stations respectively. The first component vibrating plate 4 conveys the first bottle cap assembly to the first loading mechanism 7, and the second component vibrating plate 5 conveys the second bottle cap assembly to the second loading mechanism 8. The guiding component 14 is used for material conveying and temporary storage. During operation, the loading robot 15 of the first loading mechanism 7 picks up the first bottle cap assembly and transfers it to the fixed fixture 13 of the rotary table 12; the rotary drive device 11 drives the rotary table 12 to rotate, moving the fixed fixture 13 carrying the first assembly to the second loading mechanism 8; the loading robot 15 of the second loading mechanism 8 picks up the second bottle cap assembly and stacks it on top of the first assembly. Subsequently, the rotary table 12 continues to rotate, sending the stacked bottle cap assembly to the pressing mechanism 9. During pressing, the upper cylinder 17 and the lower cylinder 18 operate synchronously: the upper cylinder 17 drives the pressing block 19 to press down the second cap assembly, while the lower cylinder 18 drives the top column 20 to push the first cap assembly upward. The fixing fixture 13 has through holes at corresponding positions to allow the top column 20 to extend, achieving bidirectional synchronous pressing and ensuring that the two cap assemblies are quickly pressed and fixed, completing the assembly. Finally, the unloading mechanism 10 removes the assembled caps from the fixing fixture 13, realizing a fully automated cap assembly process and effectively improving production efficiency.

[0022] Example 2:

[0023] Example 2:

[0024] In this embodiment, the frame 1 is fixedly mounted with a worktable 3, and the feeding mechanism 2 includes a first component vibratory plate 4 and a second component vibratory plate 5. The worktable 3 is fixedly mounted with a rotating mechanism 6, a first feeding mechanism 7, a second feeding mechanism 8, a pressing mechanism 9, and a discharging mechanism 10. The rotating mechanism 6 includes a rotating drive device 11 and a rotating table 12, and a fixing fixture 13 is fixedly mounted on the rotating table 12. The first feeding mechanism 7 and the second feeding mechanism 8 both include a guiding component 14 and a feeding robot 15. The pressing mechanism 9 includes a first support 16, an upper cylinder 17, and a lower cylinder 18. The upper cylinder 17 is fixedly mounted on the first support 16, a pressure block 19 is fixedly mounted on the driving end of the upper cylinder 17, and a top column 20 is fixedly mounted on the driving end of the lower cylinder 18.

[0025] During the operation of the bottle cap assembly machine, the feeding mechanism 2 is responsible for conveying two different bottle cap components to their respective loading stations. The first component vibratory feeder 4, through vibration and track guidance, arranges the first bottle cap components in an orderly manner and conveys them to the guide component 14 of the first loading mechanism 7. The guide component 14 serves as a temporary storage and guide, ensuring a stable supply of the first bottle cap components. Simultaneously, the second component vibratory feeder 5 conveys the second bottle cap components to the guide component 14 of the second loading mechanism 8 in a similar manner. The guide component 14 adopts a slide or guide rail structure, which can be customized according to the shape of the bottle cap components, ensuring smooth material flow without jamming. The loading robot 15 is a pneumatic or electric gripper capable of accurately grasping the bottle cap components and transferring them to the designated position.

[0026] The rotating mechanism 6, as the core component of the bottle cap assembly, drives the rotary table 12 to rotate periodically via a rotating drive device 11. The rotating drive device 11 can be a stepper motor or a servo motor, working in conjunction with a reducer to achieve precise angle control. Multiple fixing fixtures 13 are evenly distributed on the rotary table 12, each fixture 13 used to support and position the bottle cap assembly. The design of the fixing fixtures 13 matches the shape of the bottle cap assembly, ensuring stability during transfer and pressing. The rotation of the rotary table 12 sequentially delivers the fixing fixtures 13 to different workstations, enabling a continuous assembly process.

[0027] The loading robot 15 of the first loading mechanism 7 picks up the first bottle cap assembly from the guide component 14 and accurately places it into the fixture 13 of the rotary table 12. After placement, the rotary drive device 11 drives the rotary table 12 to rotate a certain angle, moving the fixture 13 carrying the first bottle cap assembly to the corresponding workstation of the second loading mechanism 8. The loading robot 15 of the second loading mechanism 8 then moves, picking up the second bottle cap assembly from the guide component 14 and stacking it on top of the first bottle cap assembly in the fixture 13. During the stacking process, the loading robot 15 ensures the initial alignment of the second bottle cap assembly with the first bottle cap assembly through visual or mechanical positioning.

[0028] After stacking is complete, the rotary table 12 continues to rotate, delivering the fixing fixture 13 containing the stacked bottle cap assemblies to the pressing mechanism 9. The first support 16 of the pressing mechanism 9 provides stable support, with the upper cylinder 17 and lower cylinder 18 mounted on the upper and lower sides of the support, respectively. During pressing, the upper cylinder 17 drives the pressure block 19 downwards, applying downward pressure to the second bottle cap assembly; simultaneously, the lower cylinder 18 drives the top column 20 upwards, pushing the first bottle cap assembly through the through-hole at the bottom of the fixing fixture 13. This bidirectional synchronous pressing method ensures that the two bottle cap assemblies are subjected to uniform compressive force, quickly pressing and fixing them together. The design of the pressure block 19 and top column 20 takes into account the contact surface shape of the bottle cap assemblies, avoiding damage to the components during pressing. After pressing is completed, the upper cylinder 17 and lower cylinder 18 reset, preparing for the next pressing operation.

[0029] Finally, the rotary table 12 transfers the assembled bottle caps to the unloading mechanism 10. The unloading mechanism 10 uses a robotic arm or pusher to remove the finished bottle caps from the fixed fixture 13 and transfer them to a collection container or conveyor belt, completing the entire assembly process. The bottle cap assembly machine achieves continuous operation through automated control, with coordinated actions of each mechanism to ensure stable assembly efficiency and quality. The periodic rotation of the rotary mechanism 6 allows multiple fixed fixtures 13 to be in different positions simultaneously, enabling parallel operation and further improving production efficiency. The entire system monitors the status of each stage through sensors and controllers to ensure operational reliability and safety.

[0030] Example 3:

[0031] In this embodiment, the loading robot 15 serves as the core execution component of the first loading mechanism 7 and the second loading mechanism 8. It is responsible for precisely gripping bottle cap assemblies from the end of the guide assembly 14 and transferring them to the fixed fixture 13 of the rotary table 12. The main structure of the loading robot 15 includes a fixed frame 21, an X-axis cylinder 22, an X-axis moving stage 24, a Z-axis cylinder 25, a Z-axis moving stage 27, a clamping cylinder 28, and a chuck 29. The fixed frame 21 is securely bolted to a designated position on the worktable 3, providing a stable support base for the entire robot. The X-axis cylinder 22 is horizontally fixedly mounted on the upper part of the fixed frame 21, with its piston rod arranged horizontally. The fixed frame 21 also has the X-axis moving stage 24 movably mounted via an X-axis slide rail 23, ensuring that the moving stage can only slide horizontally. The drive end of the X-axis cylinder 22, i.e. the end of the piston rod, is fixedly connected to the X-axis moving stage 24 through a connector, so that the extension and retraction of the cylinder can directly drive the moving stage to move precisely in the X-axis direction.

[0032] The X-axis moving stage 24 serves as the mounting platform for the vertically moving components. A Z-axis cylinder 25 is vertically fixed to its side, with the piston rod of the cylinder arranged vertically. Simultaneously, a Z-axis moving stage 27 is movably mounted on the X-axis moving stage 24 via a Z-axis slide rail 26, which restricts the moving stage to slide only vertically. The drive end of the Z-axis cylinder 25 is fixedly connected to the Z-axis moving stage 27, thereby controlling the lifting and lowering of the Z-axis moving stage 27 through the extension and retraction of the cylinder. A clamping cylinder 28 is fixedly mounted at the lower end of the Z-axis moving stage 27, and a chuck 29 for gripping bottle cap assemblies is fixedly mounted at the drive end of the clamping cylinder 28. The chuck 29 employs a double-jaw or triple-jaw structure, and its opening and closing are precisely controlled by the clamping cylinder 28 to accommodate the gripping needs of bottle cap assemblies of different sizes.

[0033] The workflow of the loading robot 15 begins with the clamping action. When the bottle cap assembly is conveyed to the predetermined loading station by the guide assembly 14, the clamping cylinder 28 drives the chuck 29 to close, reliably clamping and fixing the bottle cap assembly. Subsequently, the Z-axis cylinder 25 actuates, driving the Z-axis moving stage 27 to rise along with the clamped bottle cap assembly, causing the assembly to move out of the guide area and avoid interference. Next, the X-axis cylinder 22 drives the X-axis moving stage 24 to extend outward, moving the entire vertical motion unit and the bottle cap assembly horizontally to a position directly above the fixed fixture 13 on the rotary table 12. At this time, the Z-axis cylinder 25 reverses its action, driving the Z-axis moving stage 27 to descend, accurately placing the bottle cap assembly into the receiving cavity of the fixed fixture 13. Once in position, the clamping cylinder 28 controls the chuck 29 to release, and the bottle cap assembly is stably placed on the fixed fixture 13, completing the loading operation. Finally, the loading robot 15 executes a reset sequence: the Z-axis cylinder 25 first drives the chuck 29 to rise and leave the fixture, then the X-axis cylinder 22 retracts, causing the robot to return to its initial position, awaiting the next work cycle. The entire loading process is automated through cylinder timing control, resulting in smooth movements and accurate positioning.

[0034] The key design feature of this loading robot 15 lies in its modular pneumatic drive structure. Through a combination of linear motion along the X and Z axes, it achieves precise transfer of bottle cap components within a two-dimensional plane. X-axis cylinder 22 handles the horizontal feeding stroke, while Z-axis cylinder 25 handles the vertical pick-and-place motion. Their coordinated operation ensures a rational and efficient loading path. Clamping cylinder 28 is specifically responsible for gripping and releasing, and its gripper 29 design guarantees stability and non-destructive operation during the gripping process. All cylinders are connected to the control system via solenoid valves, allowing for adjustment of movement speed and pause time according to the assembly rhythm, adapting to different production cycle requirements. The application of a slide rail structure further improves the guiding accuracy and smoothness of the moving table, reducing wear and error accumulation over long-term use. This robot structure not only simplifies maintenance but also reduces manufacturing costs through standardized cylinder components, making it particularly suitable for mass deployment in automated assembly equipment.

[0035] In the overall workflow of the bottle cap assembly machine, the loading robot 15 of the first loading mechanism 7 is responsible for transferring the first bottle cap assembly to the fixed fixture 13, while the robot of the second loading mechanism 8 is responsible for stacking the second assembly onto the already positioned first assembly. The two robots have identical structures, differing only in their installation position and working sequence, demonstrating the advantages of standardized and modular equipment design. Through the intermittent rotation of the rotary table 12, the fixed fixture 13 passes through each station sequentially. Each movement of the loading robot 15 is synchronized with the positioning signal of the rotary table 12, ensuring the repeatability and accuracy of the component placement. This design effectively replaces traditional manual operation, solving problems such as difficult alignment, high labor intensity, and poor consistency in multi-component bottle cap assembly, thus providing a functional solution.

[0036] Example 4:

[0037] The feeding mechanism 10 in this embodiment includes an ejection assembly 30 and a guide assembly 31. The ejection assembly 30 includes a second bracket 32, on which an ejection cylinder 33 is fixedly mounted. A guide post 35 is movably mounted on the second bracket 32 ​​via a flange structure 34. The driving end of the ejection cylinder 33 is fixedly connected to the guide post 35. The guide assembly 31 includes a third bracket 36, on which an arc-shaped baffle 37 and a guide plate 38 are fixedly mounted. After the bottle cap is assembled, the rotary table 12 moves the bottle cap to the feeding mechanism 10. The ejection cylinder 33 extends, driving the guide post 35 through the fixed fixture 13 and lifting the bottle cap. Simultaneously, guided by the arc-shaped baffle 37, the bottle cap falls into the guide plate 38 and is then guided by the guide plate 38 into the collection box.

[0038] The design of the unloading mechanism 10 ensures that the bottle caps can be efficiently and stably removed from the fixture 13 and transferred to the collection bin after assembly. The ejection assembly 30 provides a stable support structure through the second bracket 32, and the ejection cylinder 33 serves as the power source, driving the guide column 35 to move linearly. The guide column 35 is movably mounted on the second bracket 32 ​​through the flange structure 34. This mounting method allows the guide column 35 to move along a predetermined path under the drive of the ejection cylinder 33, while maintaining the accuracy and stability of the movement. When the rotary table 12 moves the fixture 13 carrying the assembled bottle caps to the unloading station, the ejection cylinder 33 is activated, pushing the guide column 35 upward. The guide column 35 passes through the through hole at the bottom of the fixture 13, acting directly on the bottom of the bottle cap, lifting the bottle cap from the fixture. This process avoids jamming or damage to the bottle cap during removal, ensuring the integrity of the product.

[0039] The guiding component 31 receives the lifted bottle caps and guides them smoothly into the collection bin. The third support 36, serving as the supporting base for the guiding component 31, is fixedly installed on the workbench 3. An arc-shaped baffle 37 is located on one side of the fixed fixture 13; its arc-shaped structure effectively guides the bottle caps to move in a predetermined direction during the lifting process, preventing them from deviating or falling. A guide plate 38 is connected below the arc-shaped baffle 37, forming an inclined slide. Guided by the arc-shaped baffle 37, the bottle caps naturally slide into the guide plate 38 and, relying on gravity, slide down along the guide plate 38 to the collection bin. The guide plate 38 has a smooth surface and a reasonable angle, ensuring that the bottle caps do not roll or collide during sliding, thus guaranteeing smooth and safe material feeding.

[0040] The entire unloading process is coordinated with the movement of the rotating mechanism 6. The rotating drive device 11 controls the rotating table 12 to rotate at a predetermined rhythm, sequentially delivering the fixed fixture 13 to each workstation. When the fixed fixture 13 reaches the unloading station, the ejection component 30 activates in time to complete the ejection operation of the bottle cap. The guide component 31 is responsible for subsequent guiding and collection. This design achieves continuous automation of bottle cap assembly without manual intervention, significantly improving production efficiency. At the same time, the unloading mechanism 10 has a simple and reliable structure, is easy to maintain, and is suitable for large-scale production environments. Through the synergistic action of ejection and guidance, the bottle cap can be quickly and accurately moved out of the assembly station, freeing up space for subsequent production stages and ensuring the continuity and efficiency of the entire assembly process.

[0041] Example 5:

[0042] In this embodiment, a fourth bracket 39 is fixedly installed on the workbench 3, and a first laser detector 40 is fixedly installed on the fourth bracket 39. The first laser detector 40 is used to detect whether a bottle cap assembly is placed on the fixed fixture 13, to avoid errors in the subsequent operation of the mechanism. The fourth bracket 39 serves as a support structure to ensure that the first laser detector 40 maintains a stable position on the workbench 3, thereby accurately aligning with the detection area of ​​the fixed fixture 13. The first laser detector 40 monitors the status of the fixed fixture 13 in real time by emitting a laser beam and receiving the reflected signal. When the loading robot 15 of the first loading mechanism 7 places the first bottle cap assembly into the fixed fixture 13, the first laser detector 40 will detect the presence of the assembly and send a confirmation signal to the control system. If no bottle cap assembly is placed on the fixed fixture 13, the first laser detector 40 will detect an anomaly, trigger an alarm or suspend subsequent operations to prevent the pressing mechanism 9 or the unloading mechanism 10 from being damaged or producing waste due to no-load operation.

[0043] During the bottle cap assembly process, the detection action of the first laser detector 40 occurs before the rotation mechanism 6 rotates. Specifically, after the first feeding mechanism 7 completes the feeding of the first bottle cap assembly, the rotary drive device 11 prepares to drive the rotary table 12 to rotate, transferring the fixed fixture 13 to the station of the second feeding mechanism 8. At this time, the first laser detector 40 first performs a detection to ensure that the first bottle cap assembly is correctly placed on the fixed fixture 13. If the detection passes, the control system allows the rotation mechanism 6 to continue operating; if the detection fails, the system will immediately stop the rotation and prompt the operator to check the feeding process. This design effectively avoids subsequent steps errors caused by feeding mistakes, such as the second feeding mechanism 8 attempting to stack the second assembly on an empty fixture, or the pressing mechanism 9 performing ineffective pressing on an empty fixture.

[0044] The first laser detector 40 is optimized in its mounting position so that its laser beam can be vertically or obliquely irradiated onto the central area of ​​the fixture 13, covering the typical placement position of the bottle cap assembly. The height and angle of the fourth bracket 39 are adjustable to accommodate the detection needs of bottle cap assemblies of different sizes. The detection principle is based on the difference in light reflection: when there is a bottle cap assembly on the fixture 13, the laser beam is reflected by the surface of the assembly, and the receiver receives a strong signal; when the fixture 13 is empty, the laser beam may be absorbed or scattered by the bottom of the fixture, and the received signal is weak. By setting a threshold, the first laser detector 40 can reliably distinguish the presence or absence of an assembly.

[0045] Furthermore, the first laser detector 40 is integrated with the assembly machine's control system to achieve automated linkage. The detection signal is transmitted to the control unit in real time to coordinate the timing of the rotating mechanism 6, the feeding mechanism, and the pressing mechanism 9. For example, the control system only initiates the rotation command of the rotary table 12 after the first laser detector 40 confirms successful feeding, ensuring the continuity and safety of the production process. This detection mechanism not only improves assembly accuracy but also reduces errors caused by manual intervention, making it particularly suitable for high-speed, continuous automated production lines.

[0046] In practical applications, the use of the first laser detector 40 enhances the reliability of the bottle cap assembly machine. For example, during long-term operation, the loading robot 15 may misplace parts due to wear or interference. The first laser detector 40 can promptly detect such anomalies, preventing defective products from entering subsequent stages. Simultaneously, the detection data can be recorded for production statistics, helping to optimize equipment maintenance cycles. Overall, this embodiment, by integrating the first laser detector 40, achieves real-time monitoring of the bottle cap assembly process, ensuring efficient and stable equipment operation.

[0047] Example 6:

[0048] The guiding assembly 14 in this embodiment includes a vibrator 41 and a guiding channel 42. The vibrator 41 is fixedly installed on the guiding channel 42, and a placement component 43 is fixedly installed at one end of the guiding channel 42. When the vibrator 41 is working, it generates continuous vibration, which is transmitted to the bottle cap assembly through the guiding channel 42, causing the bottle cap assembly to move smoothly along the inner wall of the guiding channel 42. The guiding channel 42 is designed with an inclined or curved structure to guide the bottle cap assembly to slide gradually from the outlet of the feeding mechanism 2 to the placement component 43. The vibration frequency and amplitude of the vibrator 41 can be adjusted according to the size and weight of the bottle cap assembly to ensure that the bottle cap assembly does not get stuck or flip over during movement and maintains the correct orientation. The placement component 43 is located at the end of the guiding channel 42, and its interior forms a receiving space for temporarily storing the bottle cap assembly. When the bottle cap assembly reaches the placement component 43, the vibrator 41 continues to work, so that the bottle cap assembly is neatly arranged in the placement component 43, making it easy for the loading robot 15 to accurately grasp it. This design enables automatic conveying and temporary storage of bottle cap components, reducing manual intervention and improving feeding efficiency.

[0049] During the operation of the bottle cap assembly machine, the guide assembly 14, as a key part of the feeding mechanism, is responsible for guiding the bottle cap assemblies conveyed by the feeding mechanism 2 to the designated positions in an orderly manner. The vibrator 41 drives the bottle cap assemblies to move within the guide channel 42 through mechanical vibration. The path of the guide channel 42 is optimized to ensure that the bottle cap assemblies move forward at a stable speed. The placement component 43 not only serves as a temporary storage unit but also prevents the bottle cap assemblies from piling up or becoming misaligned through its structural design. When the loading robot 15 picks up the bottle cap assemblies, it directly aligns with the bottle cap assemblies in the placement component 43 to grip them. Due to the action of the vibrator 41, the bottle cap assemblies are always accessible, avoiding picking failures or delays. The entire guiding process is continuous and requires no interruption, ensuring the smooth operation of the assembly line. The vibration mechanism of the guide assembly 14 also helps to remove impurities from the surface of the bottle cap assemblies, improving assembly quality.

[0050] The fixed connection between the guide channel 42 and the vibrator 41 ensures efficient transmission of vibration energy. The guide channel 42 is made of wear-resistant material to withstand long-term vibration and friction. The placement component 43 is fixed to the end of the guide channel 42 by bolts or welding. Its position is precisely calculated so that the loading robot 15 can easily access it. The vibrator 41 can be electromagnetic or mechanical, and the vibration parameters are adjusted according to the characteristics of the bottle cap assembly. For example, for lightweight bottle cap assemblies, low-frequency vibration is used to avoid excessive jumping; for heavy bottle cap assemblies, the vibration intensity is increased to ensure smooth movement. The guide channel 42 may have guide grooves or baffles inside to further control the movement trajectory of the bottle cap assemblies and prevent them from colliding with each other or deviating from the path. The capacity design of the placement component 43 takes into account the working cycle of the loading robot 15, ensuring that there is a sufficient supply of bottle cap assemblies during the robot's material handling process, without causing production interruptions.

[0051] In practical applications, the guiding component 14 operates in coordination with the rotating mechanism 6 and other feeding components. After the feeding mechanism 2 outputs the bottle cap assembly, the vibrator 41 immediately activates, driving the bottle cap assembly through the guiding channel 42 into the placement component 43. The feeding robot 15, according to instructions from the control system, periodically retrieves the bottle cap assembly from the placement component 43 and transfers it to the fixed fixture 13 on the rotary table 12. The automation of the guiding component 14 reduces manpower requirements, and the vibration-assisted conveying method prevents the bottle cap assembly from getting stuck or damaged during transport. The design of the placement component 43 also allows for the buffer storage of a small number of bottle cap assemblies to cope with brief fluctuations in the feeding mechanism 2, ensuring the stability of the feeding process. The entire guiding system has a simple structure, is easy to maintain, and is suitable for assembling various bottle cap assemblies.

[0052] The vibrator 41 of the guide assembly 14 is installed in the middle or bottom of the guide channel 42 to maximize the vibration effect. The shape of the guide channel 42 may be straight or curved, depending on the equipment layout and space constraints. The placement component 43 is designed as an open or semi-closed structure to facilitate the entry and exit of the loading robot 15. The control circuit of the vibrator 41 is connected to the main control system and can automatically adjust the vibration intensity according to the assembly speed to achieve dynamic optimization. For example, when the assembly line accelerates, the vibrator 41 increases the frequency to speed up the conveying of the bottle cap assembly; conversely, it decreases the frequency to save energy. The inlet of the guide channel 42 is connected to the outlet of the feeding mechanism 2 to ensure a seamless transition of the bottle cap assembly. The bottom of the placement component 43 may be equipped with a sensor to detect the presence of the bottle cap assembly and feed back information to the control system to achieve intelligent feeding management.

[0053] Example 7:

[0054] In this embodiment, a second laser detector 44 is fixedly installed on the placement component 43. This detector is used to detect whether there is a bottle cap assembly in the placement component 43 and to ensure that the loading robot 15 picks up the material correctly. As the end component of the guiding component 14, the placement component 43 is driven by the vibrator 41 to guide the guiding channel 42 to transport the bottle cap assembly into the placement component 43 for temporary storage, so that the loading robot 15 can pick up the material. The second laser detector 44 is installed at a fixed position in the placement component 43, and its detection principle is based on the emission and reception mechanism of a laser beam. When the bottle cap assembly is sent into the placement component 43 by the vibrator 41, the second laser detector 44 will continuously emit a laser beam and monitor its reflection or obstruction. If there is a bottle cap assembly in the placement component 43, the laser beam will be blocked or reflected by the assembly, causing a change in the receiving end signal, thereby determining that the assembly is in place; conversely, if the placement component 43 is empty, the laser beam passes through without obstruction, the receiving end signal remains normal, indicating a material shortage.

[0055] Through this detection method, the second laser detector 44 can monitor the material status of the loading component 43 in real time, ensuring that the loading robot 15 only performs the picking action when the component is present. When a bottle cap component is detected, the system sends an allow signal to the loading robot 15, which then accurately picks up the component and transfers it to the fixed fixture 13 on the rotary table 12. If a material shortage is detected, the system will pause the loading process and may trigger an alarm or wait for replenishment, avoiding the robot grabbing empty or misoperating. This design effectively improves the reliability and automation of the loading process, reducing production interruptions or incorrect assembly caused by material shortages.

[0056] In the overall operation of the bottle cap assembly machine, the second laser detector 44 works in conjunction with the feeding mechanism 2, the rotating mechanism 6, and other components. For example, the first component vibratory feeder 4 and the second component vibratory feeder 5 respectively transport different bottle cap components to the placement parts 43 of the corresponding guiding component 14. The second laser detector 44 ensures that the loading robot 15 can only pick up the component after it has been placed in position at each placement part 43. This ensures the continuity of the assembly process and avoids component omission or misalignment. At the same time, the detection results can also be linked with the pressing mechanism 9 and the unloading mechanism 10 to ensure that only correctly picked components enter the pressing stage, and finally the unloading mechanism 10 completes the finished product output. Through the integration of the second laser detector 44, the entire embodiment achieves accurate detection and loading control of bottle cap components, thereby improving assembly efficiency and quality consistency.
