Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, specifically to an automatic assembly and pressing device for thermos cup lid sealing components. Background Technology

[0002] The core functions of a thermos cup are heat preservation and leak prevention. The assembly quality of the sealing ring on the lid directly determines the effectiveness of these two functions. It is necessary to ensure that the sealing ring is accurately embedded in the sealing groove and pressed tightly to avoid problems such as water leakage and heat preservation performance degradation during use. As the market demand for thermos cups continues to expand, companies are increasingly demanding higher production efficiency. Traditional assembly methods that rely on manual labor or simple equipment can no longer meet the comprehensive requirements of precision, efficiency and stability for industrial mass production.

[0003] Currently, the assembly of sealing rings for insulated cup lids in the industry mainly relies on two methods: The first is purely manual assembly, where operators manually pick up the sealing rings from the material box, align them with the sealing groove on the lid based on experience, and press them in place. This method is not only labor-intensive and has low output per unit time, but the assembly accuracy also depends entirely on the operator's skill level, easily leading to problems such as sealing ring misalignment, loose pressing, and deformation, resulting in a low product qualification rate. At the same time, the continuous rise in labor costs has significantly increased the production costs for enterprises. The second method is simple automated assembly equipment. While this type of equipment improves efficiency to some extent, it still does not solve the core problem of "the difficulty of balancing assembly accuracy and efficiency." The problems are as follows: the transmission and positioning mechanisms are simple in design, mostly driven directly by a single cylinder, and lack a stable multi-stage transmission conversion and positioning locking structure. This results in uneven force and unstable clamping when the sealing ring is gripped, making it easy to fall off during transfer and difficult to accurately align with the sealing groove during pressing. In addition, most equipment does not have an effective buffer structure and real-time monitoring mechanism. Rigid pressing can easily damage the sealing ring or cup lid, and assembly defects cannot be detected in time. This leads to unqualified products flowing into subsequent processes, increasing rework costs, and ultimately failing to meet the core requirements of precision, efficiency and stability for mass production. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide an automatic assembly and pressing device for the sealing components of thermos cup lids, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly and pressing device for sealing components of thermos cup lids, used for assembling the sealing ring of thermos cup lids, including a frame, a control device arranged on the side of the frame, an XY axis feeding device arranged on the frame, a movable frame arranged at the feeding end of the XY axis feeding device, a connecting frame arranged on the movable frame, and an assembly and pressing component arranged on the connecting frame;

[0006] The assembly pressing component includes two mounting seats set in the connecting frame. The bottom ends of the two mounting seats are provided with telescopic rods. The telescopic ends of the telescopic rods are fixed with mounting plates. The mounting plates are provided with sliders. The outside of the sliders is fixed with arc-shaped plates. A second connecting plate is movably arranged in the arc-shaped plates.

[0007] When the slider slides radially along the mounting plate, the expansion action of the slider causes the arc plate to open, so that the second connecting plate abuts against the inner wall of the sealing ring.

[0008] When the sealing ring sleeved on the outer side of the second connecting plate is aligned with the inside of the cup lid, the mounting plate moves downward to press and assemble the sealing ring.

[0009] Preferably, a rotating disk for placing thermos cup lids is provided on the platform within the frame, and a material unloading robot for removing assembled thermos cup lids from the rotating disk is provided on the side of the frame.

[0010] The frame is provided with a cup lid feeding channel, and the frame is provided with a feeding robot that feeds cup lids from the cup lid feeding channel to the rotary table;

[0011] Preferably, the bottom of the movable frame is provided with a visual recognition device for real-time monitoring of the sealing ring assembly status of the assembly pressing component;

[0012] Preferably, the frame is provided with a feeding assembly, the feeding assembly includes a feeding rack on the frame platform, the feeding rack is provided with a storage cylinder for storing sealing rings, the frame platform is provided with a mounting frame, the mounting frame is provided with an electric push rod, and the output end of the electric push rod is provided with a push plate;

[0013] The inside of the feeding rack is provided with a placement rack for placing a single sealing ring on the side facing the assembly and pressing component;

[0014] The feeding rack is equipped with a sealing ring for guiding the pusher plate to slide into the placement rack via a guide ramp.

[0015] Preferably, the assembly pressing assembly includes a first connecting plate disposed between two mounting seats, a mounting rod rotatably disposed on the first connecting plate, and a spiral groove formed on the upper half of the mounting rod;

[0016] Each of the two mounting bases is equipped with a cylinder, and the output ends of the two cylinders are connected to a movable plate. The movable plate has a through hole, and the inside of the through hole is provided with a boss that matches the spiral groove.

[0017] Preferably, when the two cylinders drive the movable plate to move axially, the boss engages with the spiral groove to drive the mounting rod to rotate around its own axis.

[0018] Preferably, the mounting rod has a limiting groove, a movable column is slidably arranged in the limiting groove, and a first spring is arranged in the limiting groove. The two ends of the first spring are fixedly connected to the movable column and the inner wall of the limiting groove, respectively.

[0019] The bottom end of the movable column is provided with a connecting plate, and the connecting plate is provided with an arc-shaped groove;

[0020] The top of the slider is provided with a mounting post, and the mounting post is in contact with the inside of the arc-shaped groove;

[0021] When the mounting rod rotates, it drives the connecting plate to rotate synchronously. Through the guiding effect of the arc groove on the mounting column, it drives the slider to slide radially along the mounting plate.

[0022] Preferably, the bottom of the movable plate is provided with a docking plate, which is sleeved on the outside of the mounting rod;

[0023] A docking frame is provided on the top of the connecting plate;

[0024] Both the docking plate and the docking frame have hexagonal cross-sections;

[0025] When the movable plate moves downward along the upper half of the mounting rod, the docking plate separates from the docking frame, and the docking frame rotates synchronously with the connecting plate.

[0026] When the movable plate moves to the lower half of the mounting rod and the mating plate is in contact with the mating frame, the mating plate and the mating frame are in hexagonal insertion fit, realizing the circumferential positioning of the connecting plate and preventing it from resetting and rotating.

[0027] Preferably, at least six sliders are provided, and the six sliders are evenly distributed in an array along the circumference of the connecting plate. Each arc plate is provided with a pressure plate on its outer side, and the pressure plate is located above the second connecting plate.

[0028] Preferably, each arc-shaped plate has a sliding groove for the second connecting plate to slide in, and a second spring is provided in the sliding groove. The two ends of the second spring are fixedly connected to the inner wall of the sliding groove and the top of the second connecting plate, respectively.

[0029] When the second connecting plate abuts against the inner wall of the cup lid, as the mounting plate continues to descend, the second connecting plate compresses the second spring and retracts into the sliding groove of the arc plate. Simultaneously, the pressure plate presses the sealing ring sleeved on the outside of the second connecting plate into the sealing groove of the cup lid.

[0030] In summary, the present invention has the following main beneficial effects:

[0031] 1. When the movable plate is driven axially by the cylinder, the linear motion is converted into the circumferential rotation of the mounting rod through the meshing transmission of the boss and the spiral groove. Then, the arc groove of the connecting plate guides the slider to expand radially, so that the second connecting plate forms a uniform clamping of the sealing ring, ensuring accurate gripping and positioning. At the same time, the plug-in cooperation between the hexagonal docking plate and the docking frame effectively restricts the reset rotation of the connecting plate and ensures the stability of the clamping state. The precise displacement of the XY axis feed device and the coordinated feed of the telescopic rod, combined with the elastic retraction design of the second connecting plate, enable the sealing ring to be accurately pressed into the sealing groove of the cup lid. Combined with the real-time monitoring and feedback of the visual recognition device, the assembly defects such as sealing ring offset and deformation are greatly reduced, and the product assembly qualification rate is improved.

[0032] 2. This invention can store sealing rings in batches through the storage cylinder of the feeding component, and the cooperation between the guide ramp and the placement rack can achieve orderly supply of individual sealing rings, avoiding material congestion; the rotating disk's cyclic transfer design allows the loading, assembly, and unloading processes to be carried out in parallel, adapting to the needs of large-scale continuous production; in addition, the equipment adopts an elastic buffer structure of the first spring and the second spring, which not only ensures the flexibility of the second connecting plate in clamping and retraction, but also buffers the impact force during the pressing process, reducing the wear of parts and damage to the sealing rings;

[0033] 3. This invention integrates the processes of cup lid feeding, sealing ring feeding, assembly pressing, and finished product unloading into one unit through the control equipment on the side of the frame. It achieves fully automated operation based on the preset program. The timing and stroke parameters of each execution component are precisely controlled by the control equipment, eliminating the need for manual intervention in intermediate links. The feeding component stores sealing rings in batches through the storage cylinder, and automatically positions and supplies individual sealing rings in conjunction with the electric push rod and push plate. The cup lid is automatically gripped and transferred through the feeding channel and the feeding robot. The step-by-step rotation of the rotating disk enables the orderly flow of parts to be assembled and finished products. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The embodiments of the present invention will now be described.

[0047] Example

[0048] Please see Figures 1-10This invention provides a technical solution: an automatic assembly and pressing device for sealing components of a thermos cup lid, used for assembling the sealing ring 10 of a thermos cup lid. The device includes a frame 1, a control device 11 on the side of the frame 1, an XY-axis feed device 14 on the frame 1, a movable frame 141 at the feed end of the XY-axis feed device 14, a connecting frame 143 on the movable frame 141, and an assembly and pressing assembly 3 on the connecting frame 143. The assembly and pressing assembly 3 includes two mounting seats 31 disposed in the connecting frame 143, a telescopic rod 312 at the bottom end of the two mounting seats 31, a mounting plate 322 fixed at the telescopic end of the telescopic rod 312, a slider 36 disposed in the mounting plate 322, and an arc-shaped plate 362 fixed to the outside of the slider 36. The second connecting plate 363 is movably set in 362; when the slider 36 slides radially along the mounting plate 322, the expansion action of the slider 36 causes the arc plate 362 to open, so that the second connecting plate 363 abuts against the inner wall of the sealing ring 10; when the sealing ring 10 sleeved on the outside of the second connecting plate 363 is aligned with the inside of the cup lid, the mounting plate 322 moves downward to press and assemble the sealing ring 10. There is no need for manual hand positioning. Through the precise displacement of the XY axis feed device 14 and the controllable extension and retraction of the telescopic rod 312, combined with the radial sliding of the slider 36, the arc plate 362 is opened, so that the second connecting plate 363 stably abuts against the inner wall of the sealing ring 10, ensuring that the sealing ring 10 is subjected to uniform force during assembly, avoiding displacement, and greatly improving assembly efficiency and initial positioning accuracy;

[0049] Furthermore, a rotating disk 131 for placing thermos cup lids is set on the platform within the frame 1, and a unloading robot 132 for removing assembled thermos cup lids from the rotating disk 131 is set on the side of the frame 1; a cup lid feeding channel 121 is set on the frame 1, and a feeding robot 122 is set on the frame 1 to feed cup lids from the cup lid feeding channel 121 to the rotating disk 131. The cup lid feeding channel 121 realizes batch storage and supply of cup lids, and the feeding robot 122 accurately transfers cup lids to the rotating disk 131. The rotating disk 131 transfers cup lids to be assembled and assembled cup lids in steps, and the unloading robot 132 automatically removes the finished products, forming a continuous flow of feeding-assembly-unloading, eliminating the need for frequent manual handling and placement, reducing labor costs, and increasing the workload per unit time;

[0050] Furthermore, a visual recognition device 142 is installed at the bottom of the movable frame 141 to monitor the assembly status of the sealing ring 10 of the assembly pressing component 3 in real time. The visual recognition device 142 captures the working status of the assembly pressing component 3 in real time, and promptly detects defects such as misalignment or incomplete pressing of the sealing ring 10. This facilitates the control device 11 to quickly respond to pause or adjust, prevents unqualified products from being shipped out, improves the overall assembly qualification rate, and reduces subsequent rework costs.

[0051] Furthermore, a feeding assembly 2 is provided on the frame 1. The feeding assembly 2 includes a feeding rack 21 set on the platform of the frame 1, a storage cylinder 22 for storing sealing rings 10 on the feeding rack 21, an mounting frame 23 set on the platform of the frame 1, an electric push rod 24 set in the mounting frame 23, and a pusher plate 25 set at the output end of the electric push rod 24; a placement rack 211 for placing a single sealing ring 10 is set on the side of the feeding rack 21 facing the assembly pressing assembly 3; a guide ramp is set in the feeding rack 21 to guide the sealing rings 10 pushed by the pusher plate 25 to slide to the placement rack 211; the storage cylinder 22 can store sealing rings 10 in batches; the electric push rod 24 drives the pusher plate 25 to push the sealing rings 10, which slide precisely to the placement rack 211 via the guide ramp, realizing the orderly supply of a single sealing ring 10, avoiding material congestion or multiple materials stacking, ensuring the accuracy of the assembly pressing assembly 3 in grasping, ensuring the matching of material supply and assembly rhythm, and improving the overall production continuity;

[0052] Furthermore, the assembly pressing component 3 includes a first connecting plate 321 disposed between two mounting seats 31. A mounting rod 33 is rotatably disposed on the first connecting plate 321, and a spiral groove 331 is formed in the upper half of the mounting rod 33. A cylinder 311 is mounted in each of the two mounting seats 31. The output ends of the two cylinders 311 are connected to a movable plate 34. A through hole is formed in the movable plate 34, and a boss matching the spiral groove 331 is provided inside the through hole. The first connecting plate 321 provides stable support for the mounting rod 33. When the cylinder 311 drives the movable plate 34 to move axially, the boss engages with the spiral groove 331 to transmit power, converting linear power into circumferential rotational force of the mounting rod 33. The transmission efficiency is high and the action is precise and controllable, avoiding power transmission loss and ensuring the consistency of the subsequent sliding action of the slider 36.

[0053] Furthermore, when the two cylinders 311 drive the movable plate 34 to move axially, the boss meshes with the spiral groove 331, driving the mounting rod 33 to rotate around its own axis. Through the meshing of the boss and the spiral groove 331, the rotation speed and angle of the mounting rod 33 are precisely matched with the moving stroke of the movable plate 34. No additional driving components are needed, which simplifies the structure while ensuring smooth rotation, providing a stable power foundation for the radial sliding of the slider 36.

[0054] Furthermore, a limiting groove is provided in the mounting rod 33, and a movable column 332 is slidably arranged in the limiting groove. A first spring 333 is provided in the limiting groove, and the two ends of the first spring 333 are fixedly connected to the movable column 332 and the inner wall of the limiting groove, respectively. A connecting plate 35 is provided at the bottom end of the movable column 332, and an arc-shaped groove 351 is provided on the connecting plate 35. A mounting column 361 is provided at the top end of the slider 36, and the mounting column 361 contacts the inside of the arc-shaped groove 351. When the mounting rod 33 rotates, it drives the connecting plate 35 to rotate synchronously. The arc groove 351 guides the mounting post 361, driving the slider 36 to slide radially along the mounting plate 322. The limiting groove restricts the movement direction of the movable post 332. The first spring 333 provides elastic support, ensuring that the movable post 332 and the mounting rod 33 rotate synchronously and fit tightly. The arc groove 351 of the connecting plate 35, through its cooperation with the mounting post 361, converts the rotational motion into the radial sliding of the slider 36, causing multiple sliders 36 to expand or contract synchronously, ensuring that the clamping force of the second connecting plate 363 on the sealing ring 10 is uniform.

[0055] Furthermore, a docking plate 341 is provided at the bottom of the movable plate 34, and the docking plate 341 is sleeved on the outside of the mounting rod 33; a docking frame 352 is provided at the top of the connecting plate 35; the cross-section of the docking plate 341 and the docking frame 352 are both hexagonal; when the movable plate 34 moves downward along the upper half of the mounting rod 33, the docking plate 341 separates from the docking frame 352, and the docking frame 352 rotates synchronously with the connecting plate 35; when the movable plate 34 moves to the lower half of the mounting rod 33, and the docking plate 341 and the docking frame 352 are in contact, the docking plate 341 and the docking frame 352 are hexagonally inserted to achieve circumferential positioning of the connecting plate 35 and prevent it from resetting and rotating. The hexagonal structure of the docking plate 341 and the docking frame 352 ensures that the insertion and engagement are accurate and stable, effectively preventing the sliding block 36 from retracting due to the resetting and rotation of the connecting plate 35, ensuring the stable clamping state of the second connecting plate 363 on the sealing ring 10, and avoiding the sealing ring 10 from falling off or shifting during the assembly process;

[0056] Furthermore, at least six sliders 36 are provided, and the six sliders 36 are evenly distributed in an array along the circumference of the connecting plate 35. Each arc plate 362 is provided with a pressure plate 364 on its outside. The pressure plate 364 is located above the second connecting plate 363. The six sliders 36 are evenly distributed in an array along the circumference of the connecting plate 35, so that the arc plate 362 drives the second connecting plate 363 to fit the inner wall of the sealing ring 10 in all directions, making the clamping more stable. The pressure plate 364 above provides uniform downward pressure for the sealing ring 10 to press, ensuring that the sealing ring 10 fits the sealing groove of the cup lid completely and improving the pressing density.

[0057] Furthermore, each arc-shaped plate 362 is provided with a sliding groove for the second connecting plate 363 to slide. A second spring 3631 is provided in the sliding groove, and the two ends of the second spring 3631 are fixedly connected to the inner wall of the sliding groove and the top of the second connecting plate 363, respectively. When the second connecting plate 363 abuts against the inner wall of the cup lid, as the mounting plate 322 continues to descend, the second connecting plate 363 compresses the second spring 3631 and retracts into the sliding groove of the arc-shaped plate 362. At the same time, the pressure plate 364 presses the sealing ring 10 sleeved on the outside of the second connecting plate 363 into the sealing groove of the cup lid. The sliding groove provides sliding space for the second connecting plate 363, and the second spring 3631 realizes the elastic retraction of the second connecting plate 363, avoiding the rigid collision between the second connecting plate 363 and the inner wall of the cup lid, which would cause damage. At the same time, through the synchronous descent of the pressure plate 364, the sealing ring 10 is accurately pressed into the sealing groove of the cup lid, ensuring accurate assembly position and improving the sealing performance of the cup lid.

[0058] The working principle of this invention is as follows: The equipment is coordinated and scheduled by the control device 11 on the side of the frame 1. The entire process is automated through a preset program. The timing and stroke parameters of each execution component are precisely controlled by the control device 11. The material storage cylinder 22 of the feeding component 2 stores sealing rings 10 in batches. The sealing rings 10 fall naturally into the loading rack 21 on the lower side. The control device 11 starts the electric push rod 24 to push the push plate 25, pushing the single sealing ring 10 through the guide ramp to the placement rack 211 to complete the feeding and positioning. At the same time, the cup lids to be assembled are placed in batches into the cup lid loading channel 121. The control device 11 triggers the loading robot 122 to grab a single cup lid from the channel and accurately transfer it to the preset station of the rotating disk 131 on the platform of the frame 1. The rotating disk 131 rotates according to the program to transfer the cup lids to be assembled to the assembly and pressing station, and simultaneously transfers the assembled cup lids to the lower loading station to realize continuous operation flow.

[0059] Subsequently, the control device 11 drives the XY axis feed device 14 to start, causing the assembly pressing assembly 3 on the movable frame 141 and connecting frame 143 to move towards the placement frame 211; correspondingly, the cylinders 311 in the two mounting seats 31 start synchronously, driving the movable plate 34 to slide axially outside the mounting rod 33. The boss on the inner wall of the through hole of the movable plate 34 meshes with the spiral groove 331 of the upper half of the mounting rod 33, converting the axial sliding into circumferential rotational force, causing the mounting rod 33 to rotate around its own axis; when the mounting rod 33 rotates, its internal limiting groove The movable column 332 inside rotates synchronously with the mounting rod 33, which in turn drives the connecting plate 35 at the bottom to rotate. The arc groove 351 on the connecting plate 35 guides the mounting column 361 at the top of the slider 36, pushing the six evenly arrayed sliders 36 to slide radially outward along the mounting plate 322. The arc plate 362 outside the slider 36 opens synchronously, causing the movable embedded second connecting plate 363 to extend outward until the outer wall of the second connecting plate 363 tightly abuts against the inner wall of the sealing ring 10 on the placement frame 211, completing the clamping and positioning of the sealing ring 10.

[0060] The XY-axis feed device 14 continues to operate, driving the assembly pressing assembly 3, which holds the sealing ring 10, to move directly above the cup lid on the rotary disk 131. At this time, the cylinder 311 continues to drive the movable plate 34 to move downward. When the movable plate 34 slides past the upper half of the mounting rod 33, the connecting plate 35 stops rotating. The docking bracket 352, which previously rotated synchronously with the connecting plate 35, rotates to a position directly opposite the docking plate 341 at the bottom of the movable plate 34. The two are in a hexagonal insertion fit, restricting the reset rotation of the connecting plate 35 and ensuring the stable clamping state of the second connecting plate 363 on the sealing ring 10. When the movable plate 34 continues to move downward, the docking plate 341 pushes the connecting plate 35 synchronously. The downward movement causes the movable column 332 to slide downward within the limiting groove of the mounting rod 33, stretching the first spring 333. Simultaneously, the telescopic rod 312 at the bottom of the mounting base 31 drives the mounting plate 322 downward until the bottom of the second connecting plate 363 contacts the inner wall of the cup lid. As the downward feed continues, the inner wall of the cup lid exerts reverse pressure on the second connecting plate 363, forcing the second connecting plate 363 to compress the second spring 3631 within the arc plate 362 and retract into the sliding groove. The sealing ring 10 on its outer side loses its inner support, and the pressure plate 364 outside the arc plate 362 descends synchronously with the mounting plate 322, precisely pressing the sealing ring 10 into the pre-set sealing groove of the cup lid.

[0061] The visual recognition device 142 at the bottom of the movable frame 141 captures real-time images of the assembly area, collecting image information such as the position and fit of the sealing ring 10 after pressing, and transmits it to the control device 11. The control device 11 analyzes and compares the image data. If it meets the preset assembly standards, the assembly is deemed qualified. If an assembly defect is detected, an alarm signal is issued, and the equipment stops operating and awaits manual handling. After the assembly is qualified, the cylinder 311 drives the movable plate 34 to retract upwards, and the second connecting plate 363 first rebounds to its original position under the elastic force of the second spring 3631. Then the movable column 332... Under the recoil force of spring 333, the plate retracts into the limiting groove of mounting rod 33, causing connecting plate 35 to move upward, so that docking plate 341 and docking frame 352 are disengaged; as movable plate 34 continues to rise, its boss engages with the spiral groove 331 of mounting rod 33 again, causing mounting rod 33 to rotate in the opposite direction, and connecting plate 35 rotates in the opposite direction synchronously. Through the guiding effect of arc groove 351 on mounting column 361, slider 36 retracts radially inward along mounting plate 322, and second connecting plate 363 releases clamping of sealing ring 10, ready for the next operation;

[0062] The XY axis feed device 14 drives the assembly pressing component 3 to reset to the feeding station. The rotary table 131 transfers the assembled cup lid to the unloading station. The control device 11 starts the unloading robot 132 to grab the finished cup lid and move it to the preset storage area. After the unloading is completed, the rotary table 131 continues to rotate, and the empty station is connected to the loading robot 122 again to enter the next cycle of operation, realizing continuous automated production.
