Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, specifically to an assembly device. Background Technology

[0002] In modern industrial manufacturing, many products require the assembly of plugs and end caps on their covers. For example, in automobile manufacturing, plugs are used to seal motor covers and various container covers to prevent leakage of internal liquids or gases; end caps are used to adjust the size of fluid channels and seal unused interfaces, playing a crucial role in ensuring the normal operation and stable performance of the product.

[0003] In existing technologies, traditional manual assembly methods are not only labor-intensive and inefficient, making it difficult to meet the demands of large-scale production, but also highly susceptible to human error in assembly quality, easily leading to problems such as incomplete assembly and inadequate sealing, thus affecting the overall performance and reliability of the product. Alternatively, existing automated assembly devices are often limited to a single function, only capable of assembling one type of component, such as plugs or end caps. This necessitates the transfer of workpieces between multiple devices during the assembly process, increasing the complexity and time cost of the production process, and impacting both production efficiency and product quality.

[0025] Compared with the prior art, this application has at least the following beneficial effects:

[0026] 1. In this application, the first driving component of the displacement mechanism drives the support component to switch between the gluing station and the assembly station, enabling the cover to complete the gluing and assembly processes sequentially and continuously. This eliminates the need for manual handling of the cover between different processes, reducing waiting time in intermediate steps and significantly shortening the production cycle of a single product, thereby improving overall production efficiency.

[0044] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0045] refer to Figures 1-5 This application provides an assembly device for assembling a plug 200 and a stopper 300 onto a cover 100. The assembly device includes a displacement mechanism 400, an adhesive application mechanism 500, a plug assembly mechanism 600, a stopper assembly mechanism 700, and a feeding mechanism 800.

[0046] The displacement mechanism 400 includes a first driving member 410 and a slidable support member 420. The support member 420 supports the cover 100 and has an adhesive application station and an assembly station. The first driving member 410 is connected to the support member 420 and drives the support member 420 to switch between the adhesive application station and the assembly station. By having the first driving member 410 drive the support member 420 to switch between different stations, the cover 100 can sequentially complete different processes such as adhesive application and assembly, eliminating the need for frequent manual handling of the cover 100, greatly improving the flexibility and continuity of production, and meeting the needs of automated production.

[0047] The adhesive application mechanism 500 is used to evenly and accurately apply adhesive to the cover 100 when the support 420 is in the adhesive application position. The evenly applied adhesive can form a good sealing layer between the plug 200 and the cover 100, effectively preventing leakage of liquids, gases, etc., and improving the sealing performance and reliability of the product.

[0048] The plug assembly mechanism 600 includes a second driving component 610 and a pressing component 620. The second driving component 610 is connected to the pressing component 620 and drives the pressing component 620 to press the plug 200 into the cover 100 when the support component 420 is in the assembly position. The stable driving force provided by the second driving component 610 ensures that the plug 200 is pressed smoothly and accurately into the cover 100, avoiding damage to the plug 200 or loose assembly caused by uneven, excessive or insufficient pressure, thus improving the stability of the assembly.

[0049] The plug assembly mechanism 700 includes a third drive component 710 and a rotating component 720. The third drive component 710 is connected to the rotating component 720 and drives the rotating component 720 to screw the plug 300 into the cover 100 when the support component 420 is in the assembly position. By precisely controlling the torque and speed of the rotating component 720, a good threaded connection can be formed between the plug 300 and the cover 100, ensuring a sealing effect and preventing the plug 300 from loosening or leaking.

[0050] The feeding mechanism 800 includes a first feeding component 810, a second feeding component 820, and a positioning component 830. The first feeding component 810 feeds the plug 200 onto the pressing component 620, and the second feeding component 820 feeds the end cap 300 onto the positioning component 830 for the rotating component 720 to pick up. The feeding mechanism 800 can automatically and continuously feed the plug 200 and end cap 300 to the designated assembly position, working closely with processes such as gluing and assembly to achieve automated continuous production of the entire assembly process, improving production efficiency and capacity. The design of the positioning component 830 ensures that the end cap 300 can be accurately picked up by the rotating component 720, avoiding assembly errors caused by positional deviations of the end cap 300, and improving the accuracy and reliability of assembly.

[0051] Specifically, after the cover 100 is placed on the support 420, the first drive component 410 pushes the support 420 to the glue application station. The glue application mechanism 500 applies glue to the sealing surface of the cover 100. After completion, the support 420 is transferred to the assembly station. At this time, the first feeding component 810 conveys the plug 200 directly below the pressing component 620, and the second drive component 610 drives the pressing component 620 to press down to complete the assembly of the plug 200. Simultaneously, the second feeding component 820 conveys the plug 300 to the positioning component 830. After the rotating component 720 grabs the plug 300, the third drive component 710 drives it to rotate and screw it into the threaded hole of the cover 100. The entire process achieves process connection through station switching, and the two assembly actions are executed synchronously at the assembly station.

[0052] Compared with existing technologies, traditional equipment requires three separate machines—a glue applicator, a pressing machine, and a twisting machine—to complete the process. This application integrates these three functional modules into a single device. In existing technologies, the workpiece needs to undergo three clamping and positioning processes. This device completes all processes in a single clamping operation using the support component 420, thus reducing positioning errors.

[0053] The assembly device provided in this application realizes continuous automated operation of the gluing and assembly processes, eliminating efficiency losses caused by multiple workpiece transfers. The station switching mechanism of the support component 420 allows different processes to be separated spatially but continuous in time, improving equipment utilization. The parallel design of the plug 200 and the end cap assembly mechanism 700 allows the two assembly actions to be performed simultaneously, shortening the assembly cycle of a single product. The independent configuration of the feeding mechanism 800 avoids material mixing, and the positioning component 830 ensures the thread alignment accuracy of the end cap 300, improving the assembly qualification rate.

[0054] refer to Figures 4-8 The first feeding assembly 810 includes a first mounting base 811, a feeding element 812, and a fourth driving element 813. The fourth driving element 813 is mounted on the first mounting base 811. The first end of the feeding element 812 is retractably connected to the first mounting base 811. The fourth driving element 813 is connected to the feeding element 812 and drives the second end of the feeding element 812 to move below the pressing element 620. The first mounting base 811 is a support structure for supporting the feeding element 812 and the driving element, and can be implemented using a metal frame or a fixed plate. Its function is to provide a stable foundation for the movement of the feeding element 812. The feeding element 812 is an actuating component for conveying the plug 200, and can be implemented using a telescopic rod or a sliding table structure. Its function is to transfer the plug 200 from its initial position to its target position through telescopic movement. The fourth driving component 813 is the power source for driving the feeding component 812. Specifically, it can be implemented by a cylinder, hydraulic cylinder or electric push rod. Its function is to control the extension and retraction stroke of the feeding component 812 through linear motion, thereby adjusting the position of the feeding end.

[0055] Specifically, when the plug 200 needs to be delivered to the pressing component 620, the fourth drive component 813 is activated and pushes the feeding component 812 to extend and retract along the second direction Y. The second end of the feeding component 812 moves from its initial position to directly below the pressing component 620, at which point the plug 200 is accurately delivered to the working area of ​​the pressing component 620. Through the cooperation of the extendable feeding component 812 and the fourth drive component 813, the feeding path can be flexibly adjusted to avoid interference with surrounding mechanisms, while ensuring the positioning accuracy of the plug 200.

[0056] This application achieves dynamic adjustment of the feeding end position through the coordinated control of the retractable feeding component 812 and the fourth driving component 813, which not only adapts to the pressing requirements of different sizes but also improves the controllability of the feeding process. It solves the problems of insufficient flexibility and low positioning accuracy of the existing feeding mechanism 800, achieves precise control of the plug 200 conveying path, reduces assembly failures caused by positional deviations, simplifies the equipment structure, and reduces maintenance difficulty.

[0057] The first feeding assembly 810 also includes a material tray 814 and a fifth driving member 815. The fifth driving member 815 is located on the second end of the feeding member 812. The fifth driving member 815 is connected to the material tray 814 and drives the material tray 814 to rise and fall, so as to convey the plug 200 to the pressing member 620. The material tray 814 is a supporting component for temporarily storing the plug 200 to be assembled. Specifically, it can be a metal tray with positioning grooves whose groove shape matches the outer contour of the plug 200 to prevent the plug 200 from shifting during conveying. The fifth driving member 815 is a power unit that controls the vertical movement of the material tray 814. Specifically, it can be implemented using a cylinder or servo motor in conjunction with a lead screw structure. Through the lifting action, it precisely lifts the plug 200 on the material tray 814 to the gripping position of the pressing member 620.

[0058] Specifically, when the feeding component 812 moves to below the pressing component 620 via the fourth driving component 813, the fifth driving component 815 is activated and drives the placing tray 814 upward, so that the plug 200 reaches the predetermined gripping height of the pressing component 620. The lifting stroke of the placing tray 814 can be adjusted according to different specifications of plugs 200, for example, by adjusting the cylinder stroke or the encoder parameters of the servo motor to achieve height adaptation. During this process, the vertical alignment between the placing tray 814 and the pressing component 620 is calibrated by mechanical limit or sensor detection to ensure that the plug 200 is accurately transferred to the pressing component 620. An air suction port 621 is provided on the pressing component 620, and the pressing component 620 uses a vacuum suction cup to adsorb the plug 200 on the placing tray 814 onto the pressing component 620.

[0059] This application utilizes the lifting and adjusting function of the feeding tray 814 to dynamically match the gripping position of the pressing component 620, avoiding assembly misalignment problems caused by height errors. It achieves adjustable height and positioning accuracy for the plug 200, resolving assembly failures caused by differences in plug 200 dimensions or changes in the position of the pressing component 620. Simultaneously, it reduces the number of manual steps required to adjust the feeding height, improving the automation level of the assembly process.

[0060] The first feeding assembly 810 also includes a vibratory feeder 816, a feeding channel 817, a first feeding seat 818, an adsorption member 819a, and a sixth driving member 819. The feeding channel 817 receives the plugs 200 transported by the vibratory feeder 816 and conveys them to the first feeding seat 818. The sixth driving member 819 is connected to the adsorption member 819a and drives the adsorption member 819a to adsorb the plugs 200 on the first feeding seat 818 onto the feeding assembly 812. The vibratory feeder 816 is a feeding device that achieves the directional arrangement of parts through vibration. Specifically, it can be an electromagnetically driven vibratory feeder 816 with an internal spiral track that arranges the disordered plugs 200 in a fixed direction through vibration. The feeding channel 817 is a transmission channel for receiving the parts output by the vibratory feeder 816. Specifically, it can be an inclined slide structure that uses gravity to move the plugs 200 along the slide to the first feeding seat 818. The first placement seat 818 is a positioning structure for temporarily storing parts to be transferred. It can be implemented using a metal block with a limiting groove, the shape of which matches the shape of the plug 200. The adsorption component 819a is an actuator for transferring parts via negative pressure adsorption. It can be implemented using a vacuum nozzle, connected to a vacuum generator via an air pipe to generate adsorption force. The sixth driving component 819 is a power element that drives the adsorption component 819a to move. It can be implemented using a linear cylinder, with the piston rod extending and retracting to drive the adsorption component 819a to complete lateral displacement.

[0061] Specifically, the vibratory feeder 816 arranges the disordered plugs 200 in a preset direction and then conveys them to the feed channel 817. The plugs 200 slide along the feed channel 817 into the limiting groove of the first placement seat 818 for positioning. The sixth driving component 819 drives the adsorption component 819a to move above the first placement seat 818. After the vacuum nozzle contacts the surface of the plug 200, adsorption is initiated, fixing the plug 200 in place. Subsequently, the sixth driving component 819 drives the adsorption component 819a back to its initial position, transferring the plug 200 onto the bearing surface of the feeding component 812. This process, through the automatic feeding of the vibratory feeder 816 and the precise transfer of the adsorption component 819a, achieves continuous and stable feeding of the plugs 200.

[0062] This application achieves secondary positioning by adding a material channel 817 and a first material placement seat 818, combined with an adsorption-type transfer method, effectively eliminating the impact of part posture deviation on the transfer process and improving feeding stability. It realizes fully automatic directional feeding and precise transfer of the plug 200, avoiding feeding interruptions or positioning deviations caused by manual intervention. The cooperation between the vibratory feeder 816 and the material channel 817 ensures that the plug 200 arrives at the transfer station in the correct posture. The adsorption-type transfer method avoids potential damage to parts caused by mechanical grippers, making it particularly suitable for feeding precision parts such as rubber plugs with easily scratched surfaces.

[0063] refer to Figure 2 , Figure 5 and Figure 6 The assembly device also includes a frame 900, which includes a worktable 910 and a support frame 920. The worktable 910 is provided with a first slide rail 911 extending along the first direction X, and the support member 420 is provided with a first slide block 421, which is slidably connected to the first slide rail 911. A fourth driving member 813 drives the feeding member 812 to move in the second direction Y, and the lifting direction of the material tray 814 is the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. Among them, the worktable 910 is the basic support platform for carrying the various functional modules of the assembly device, and the support frame 920 is a vertical support structure set perpendicular to the worktable 910. Specifically, it can adopt a frame structure combining columns and beams, and is used to install the glue application mechanism 500, the plug assembly mechanism 600, and the plug assembly mechanism 700. The first slide rail 911 is a linear guide component arranged along the horizontal plane, used to guide the support member 420 to move between the glue application station and the assembly station. The first slide block 421 is a sliding component that cooperates with the first slide rail 911. Specifically, it can be a movable base with a slider, used to support the support member 420 and achieve precise displacement. The second direction Y is a horizontal movement direction perpendicular to the first direction X, which can be driven by a cylinder or servo motor to move the feeding member 812 laterally. The third direction Z is a vertical movement direction perpendicular to the first direction X and the second direction Y, which can be driven by a lifting cylinder to move the material tray 814 up and down.

[0064] Specifically, the support member 420 achieves linear movement along the first direction X through the cooperation of the first slide block 421 and the first slide rail 911, enabling the cover 100 to be accurately transferred to the assembly station for subsequent assembly after the glue is applied at the glue application station. In the feeding assembly, the fourth drive member 813 drives the feeding member 812 to move along the second direction Y, conveying the plug 200 to below the pressing member 620, while the material tray 814 rises and falls in the third direction Z to complete the material transfer. Since the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, the movement trajectory of the feeding assembly and the displacement direction of the support member 420 form a spatial orthogonal relationship, avoiding movement interference, and achieving precise positioning through the coordinated control of the three independent directions.

[0065] This application achieves precise coordination of the positioning of the cover 100, material conveying and pressing actions through an orthogonal three-axis layout, ensuring that the movement trajectories of each functional module do not interfere with each other during the assembly of the plug 200, thereby improving assembly consistency and equipment operation stability.

[0066] The support member 420 is equipped with a clamping assembly 430, which includes a support column 431 and a plurality of first clamping members 432. The support column 431 is supported below the mounting area of ​​the plug 200 on the cover 100, and the plurality of first clamping members 432 are spaced apart around the circumference of the cover 100. The support column 431 is a rigid structural member located below the cover 100 to support the mounting area of ​​the plug 200. It can be implemented as a cylindrical metal column, with a buffer pad at its top to adapt to the curved surface of the cover 100. This structure can disperse local pressure when pressing the plug 200, preventing deformation of the cover 100. The first clamping members 432 are fixing devices distributed along the outer circumference of the cover 100, and can be implemented as pneumatic grippers or hydraulic clamps. The clamping surface can be provided with anti-slip textures to enhance gripping force. Multiple first clamping members 432 are arranged at equal angular intervals in the circumferential direction to form multi-directional constraints and prevent the cover 100 from shifting during the gluing or assembly process.

[0067] Specifically, when the cover 100 is conveyed to the support member 420, the support column 431 is located directly below the mounting hole of the plug 200. Subsequently, the circumferentially distributed first clamping members 432 synchronously converge towards the edge of the cover 100, forming a three-point or four-point clamping structure. In the glue application process, the constant clamping force of the first clamping members 432 can counteract the centrifugal force generated by the rotation of the glue-spraying disc 531. In the pressing process, the support column 431 and multiple first clamping members 432 work together to prevent the cover 100 from tilting or slipping due to the pressing force of the plug 200, and to prevent sealing failure caused by deformation of the cover 100 during the pressing process.

[0068] refer to Figure 2 , Figure 9 and Figure 10The glue application mechanism 500 includes a seventh drive member 510, a second mounting base 520, a glue spinner 530, and a glue injector 540. The seventh drive member 510 is mounted on the support frame 920. The second mounting base 520 is connected to the output shaft of the seventh drive member 510. The glue spinner 530 and the glue injector 540 are both mounted on the second mounting base 520. The glue injector 540 is used to inject glue into the glue spinner disc 531 of the glue spinner 530. When the support member 420 is in the glue application position, the seventh drive member 510 drives the mounting base to move down so that the glue spinner disc 531 of the glue spinner 530 is close to the cover 100. The glue spinner disc 531 of the glue spinner 530 rotates to apply glue to the cover 100.

[0069] The seventh driving component 510 is a power element used to drive the mounting base to move vertically. It can be implemented using a pneumatic or electric cylinder, and its function is to provide precise lifting control for the glue-spinning disc 531. The glue-spinning device 530 is a device that achieves uniform glue distribution through centrifugal force. It can be implemented using a structure where a motor drives the glue-spinning disc 531 to rotate. Its function is to evenly spin the glue delivered by the glue dispenser 540 onto the surface of the cover 100. The glue dispenser 540 is a device for quantitatively delivering glue. It can be implemented using a glue gun structure with a metering pump, and its function is to provide a controllable glue supply to the glue-spinning disc 531. The glue application mechanism 500 may also include a collection box 580, which is located below the glue-spinning disc 531 of the glue-spinning device 530 after the glue-spinning device 530 has finished spinning the glue. The position switching of the collection box 580 is synchronized with the glue-spraying action. It moves to the predetermined position immediately after the glue application stage is completed, ensuring timely glue recycling, reducing the frequency of manual intervention, and improving the cleanliness of the glue application process and overall assembly efficiency.

[0070] Specifically, when the support member 420 carries the cover 100 to the glue application station, the seventh drive member 510 pushes the second mounting base 520 downwards, causing the glue-spraying disc 531 to enter the mounting hole of the cover 100. After the glue injector 540 injects a measured amount of glue into the center of the glue-spraying disc 531, the glue-spraying disc 531 rotates at high speed under the drive of the motor, and the glue forms a uniform annular film under the action of centrifugal force. As the glue-spraying disc 531 continues to rotate, the glue film is sprayed onto the surface of the cover 100 to form a continuous glue layer of uniform thickness.

[0071] This application utilizes the centrifugal force generated by the rotation of the glue-spraying disc 531 to achieve glue diffusion, eliminating human error. Simultaneously, the coordinated control of the glue dispenser 540 and the glue-spraying disc 530 precisely matches the glue dosage and spraying speed. This achieves automated and uniform glue coating on the surface of the cover 100, avoiding glue accumulation or gaps, and ensuring reliable sealing during the subsequent assembly of the plug 200 and the cap 300. The linked control of the glue-spraying disc 531 and the glue dispenser 540 further reduces glue waste, and the glue application process requires no manual intervention, significantly improving assembly efficiency.

[0072] The glue application mechanism 500 also includes a glue storage tank 550, a pressure relief valve 560, and a level sensor 570. The glue storage tank 550 is connected to the glue dispenser 540 and supplies glue to the glue dispenser 540. The pressure relief valve 560 is connected to the glue storage tank 550, and the level sensor 570 is used to detect the amount of glue in the glue storage tank 550. The glue storage tank 550 is a sealed container for storing glue and is connected to the glue dispenser 540 via a pipe to continuously supply glue to the glue dispenser 540, preventing the glue application process from stopping due to glue supply interruption. The pressure relief valve 560 is a safety device for regulating the internal pressure of the glue storage tank 550. Specifically, it can be a spring-loaded pressure control valve that automatically opens to release pressure when glue needs to be added to the glue storage tank 550 or when the internal pressure exceeds a set threshold, preventing glue leakage or spraying due to abnormal pressure. The liquid level sensor 570 is a detection device used to monitor the amount of glue in the glue storage tank 550. Specifically, it can be a capacitive or ultrasonic sensor. By providing real-time feedback on the amount of glue, it ensures that the remaining amount of glue is within a controllable range during the glue application process.

[0073] Specifically, the glue storage tank 550 is connected to the glue dispenser 540 via a delivery pipe, and the glue enters the glue dispenser 540 under gravity or pressure. A pressure relief valve 560 is installed on the top of the glue storage tank 550 to maintain a stable pressure within the tank through pressure balancing, preventing uneven glue application to the glue-spraying tray 531 due to pressure fluctuations during glue delivery. A level sensor 570 is vertically installed on the side wall of the glue storage tank 550. When the glue level is detected to be below a preset threshold, an alarm signal is triggered, prompting the operator to replenish the glue in time. During the glue application process, the glue storage tank 550, the pressure relief valve 560, and the level sensor 570 work together to ensure a stable glue supply pressure and sufficient quantity. This application achieves sealed glue storage by adding a glue storage tank 550, and automatically regulates the pressure with the pressure relief valve 560, avoiding glue waste or equipment damage due to abnormal pressure. The introduction of the level sensor 570 further solves the problem of low efficiency in manually checking the glue level, realizing automated monitoring of the glue application process.

[0074] refer to Figure 2 , Figure 5 and Figure 11The second feeding assembly 820 includes a material placement plate 821, a third mounting base 822, a second clamping member 823, an eighth driving member 824, a ninth driving member 825, and a tenth driving member 826. The worktable 910 is provided with a second slide rail 912 extending along the first direction X. The third mounting base 822 is slidably mounted on the second slide rail 912. The third mounting base 822 is provided with a third slide rail 822a extending along the second direction Y. The eighth driving member 824 is mounted on the support frame 920. The ninth drive component 825 is mounted on the third mounting base 822; the eighth drive component 824 is connected to the third mounting base 822 and drives the third mounting base 822 to slide along the second slide rail 912; the ninth drive component 825 is connected to the tenth drive component 826 and drives the tenth drive component 826 to slide along the third slide rail 822a; the tenth drive component 826 is connected to the second clamping component 823 and drives the second clamping component 823 to rise and fall, so as to transport the plug 300 from the material plate 821 to the positioning component 830.

[0075] The material placement plate 821 is a planar support component for placing the plug 300, which can be made of metal or plastic. Positioning grooves or locking structures can be provided on its surface to fix the position of the plug 300. The third mounting base 822 is a movable base supporting the conveying path of the plug 300, which can achieve linear displacement along the first direction X through a combination of slide rails and driving components. The second clamping component 823 is an end effector that performs the gripping action of the plug 300, which can be implemented using pneumatic grippers or electromagnetic chucks. The eighth driving component 824, the ninth driving component 825, and the tenth driving component 826 represent power sources for different axial movements, which can be implemented using servo motors or cylinders, respectively controlling the horizontal movement of the third mounting base 822, the lateral movement of the tenth driving component 826, and the vertical movement of the second clamping component 823.

[0076] Specifically, when the plug 300 needs to be transferred from the placement plate 821 to the positioning assembly 830, the eighth drive member 824 drives the third mounting base 822 to move along the second slide rail 912 in the first direction X to directly above the placement plate 821. Subsequently, the ninth drive member 825 drives the tenth drive member 826 to move laterally along the third slide rail 822a in the second direction Y, so that the second clamping member 823 is aligned with the plug 300. The tenth drive member 826 drives the second clamping member 823 to descend to the surface of the placement plate 821, and after gripping the plug 300, it is vertically lifted. Finally, the eighth drive member 824 and the ninth drive member 825 work together to move the third mounting base 822 above the positioning assembly 830, and the tenth drive member 826 controls the second clamping member 823 to descend and release the plug 300, completing the precise positioning and conveying of the plug 300.

[0077] In some specific embodiments, the second slide rail 912 may be equipped with a limit sensor to control the travel of the third mounting base 822. A pressure sensor may be installed at the end of the second clamping member 823 to detect the gripping state of the plug 300. An array of positioning holes may be provided on the surface of the material placement plate 821 to match the placement requirements of plugs 300 of different specifications.

[0078] This application achieves independent and precise adjustment of the plug 300 in the horizontal, lateral and vertical directions through the coordinated control of the three-axis drive system. This effectively avoids positioning deviations caused by multi-process transfer, reduces manual intervention, solves the problem of surface damage to the plug 300 caused by multiple handling in the traditional feeding process, and improves the continuity and stability of the assembly process.

[0079] The positioning component 830 includes a second material placement seat 831 and a plurality of positioning blocks 832 disposed on the second material placement seat 831. The clamping and positioning of the plug 300 is achieved by driving the opening and closing movement of the plurality of positioning blocks 832 through a driving structure.

[0080] The plug assembly mechanism 700 also includes a fourth mounting base 730, an eleventh driving member (not shown), and a twelfth driving member 740. A fourth slide rail 921 is provided on the support frame 920. The fourth mounting base 730 is sleeved on the fourth slide rail 921. The eleventh driving member is connected to the fourth mounting base 730 and drives the fourth mounting base 730 to slide along the fourth slide rail 921. A fifth slide rail 731 is provided on the fourth mounting base 730. A third driving member 710 is slidably provided on the fifth slide rail 731. The twelfth driving member 740 is connected to the third driving member 710 and drives the third driving member 710 to rise and fall, so as to transport the plug 300 on the positioning assembly 830 to the rotating member 720.

[0081] The fourth mounting base 730 is a support structure for supporting the movement of the plug assembly mechanism 700. Driven horizontally along the fourth slide rail 921 by the eleventh driving component, it ensures the plug assembly mechanism 700 can move between the positioning component 830 and the support component 420. The eleventh driving component is a power element that controls the movement of the fourth mounting base 730; for example, a linear motor or cylinder can be used. Through linear motion, it drives the fourth mounting base 730 to be precisely positioned on the fourth slide rail 921. The fourth slide rail 921 is a guide structure mounted on the support frame 920, used to constrain the movement trajectory of the fourth mounting base 730 and ensure the stability of horizontal movement. The fifth slide rail 731 is a vertical guide structure set on the fourth mounting base 730, used to constrain the lifting path of the third driving component 710. The twelfth driving component 740 is a power element that controls the vertical movement of the third driving component 710; for example, a servo motor combined with a lead screw structure can be used to transfer the plug 300 from the positioning component 830 to the rotating component 720 through lifting motion, ensuring accurate gripping position.

[0082] Specifically, after the plug 300 is conveyed to the positioning component 830 by the second feeding component 820, the eleventh drive component drives the fourth mounting base 730 to move along the fourth slide rail 921 above the positioning component 830. The twelfth drive component 740 drives the third drive component 710 to descend along the fifth slide rail 731 to the position of the plug 300. After the third drive component 710 grabs the plug 300, the twelfth drive component 740 drives it to rise and reset. The eleventh drive component drives the fourth mounting base 730 to move to the working area of ​​the rotating component 720. The twelfth drive component 740 again drives the third drive component 710 to descend, transferring the plug 300 to the rotating component 720. Under the rotational drive of the third drive component 710, the rotating component 720 completes the threaded assembly of the plug 300 with the cover 100. The entire process ensures the accuracy of the plug 300 grabbing and assembly through dual positioning in both horizontal and vertical directions.

[0083] This application utilizes a composite motion structure of the fourth slide rail 921 and the fifth slide rail 731, combined with the coordinated control of the eleventh and twelfth drive components 740, to achieve precise position adjustment of the plug 300 in the horizontal and vertical directions, effectively solving the positioning accuracy problem in multi-station collaborative operations. Furthermore, it enables stable transfer of the plug 300 from the positioning component 830 to the rotating component 720, ensuring that the plug 300's posture and position before being screwed into the cover 100 meet assembly requirements, reducing the risk of thread damage to the plug 300 due to positioning deviations.

[0084] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).
