Description

Technical Field

[0001] This invention relates to the field of automatic glue dispensing equipment technology, and in particular to a quick-change glue bucket lifting and docking device. Background Technology

[0002] In the cigarette manufacturing process, cigarette making machines continuously consume glue for processes such as cigarette bonding and packaging lamination. Currently, the industry commonly uses AGV (Automated Guided Vehicle) intelligent carts to carry glue buckets for glue supply. The AGV travels between the glue supply station and each cigarette making machine to automatically replenish the glue. When the glue in the bucket is depleted, the AGV carries the empty bucket back to the glue supply station to replenish the glue, and then goes to the corresponding machine to perform the next round of glue supply.

[0003] In the current glue supply model, the glue tank and the AGV body are mostly fixed and integrated structures that cannot be separated. During the glue replenishment operation, the AGV must be parked at the glue station and wait for the glue tank to be filled. At the same time, each AGV can only handle a single type of glue, resulting in extremely low utilization of AGV equipment and very limited glue supply coverage of a single AGV. If there are many cigarette making machines in the workshop and the glue supply demand is large, a large number of AGVs need to be configured to match the production rhythm, resulting in high equipment investment costs and daily operation and maintenance costs.

[0004] To address these challenges, the industry has been exploring quick-change glue supply solutions that allow for the separation of glue buckets from AGVs. However, there is currently no dedicated glue-filling docking device suitable for this quick-change mode. Traditional fixed glue-filling joints require extremely high precision in the placement of the glue buckets. After being placed by the AGV, the glue buckets generally exhibit positional deviations. If a rigid lifting method is used for direct docking, misalignment, collision damage, and even glue leakage are likely to occur. If manual alignment is relied upon, the automation level is low and the glue replenishment efficiency is poor, failing to meet the unmanned and automated operation requirements of cigarette production workshops.

[0005] Therefore, there is an urgent need for a quick-change glue drum adding and lifting docking device that can automatically compensate for docking position deviations and achieve precise and flexible docking to meet the automated glue replenishment needs of quick-change glue drums. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide a quick-change glue bucket adding and lifting docking device to overcome the shortcomings of existing glue replenishment docking technology, which is unable to adapt to the development needs of quick-change glue bucket glue supply mode, and has the defects of low docking error tolerance, insufficient automation and low utilization rate of AGV equipment.

[0007] The technical solution adopted by this invention to solve its technical problem is: a quick-change glue bucket adding and lifting docking device, comprising: frame; The lifting mechanism includes a bracket that is slidably mounted on the frame in a vertical direction and a lifting drive device connected to the bracket. The lifting drive device is used to drive the bracket to lift the quick-change glue bucket to be glued. The quick-change glue bucket is provided with a glue injection joint and a guide hole at its top. The assembly includes a connector docking module mounted on the top of the frame, above the lifting mechanism. The connector docking module comprises a flexible mechanism fixedly mounted on the frame, a connector mounting plate rotatably mounted on the frame and supported by the flexible mechanism to maintain itself in a reference docking position under natural conditions, and an adhesive-filling connector and a guide pin fixedly mounted on the connector mounting plate. The guide pin is used to engage with the guide hole to guide the adhesive-filling connector and the glue-injecting connector to coaxially dock. When there is a positional deviation during docking, the guide pin, under the lateral force of the guide hole, can cause the connector mounting plate to sway around the rotation center axis. Simultaneously, the flexible mechanism undergoes elastic deformation to adaptively compensate for the docking positional deviation.

[0008] As a further improvement of the present invention, the connector mounting plate is L-shaped, comprising a back plate distributed in the vertical direction and a fixing plate distributed in the horizontal direction. The back plate is rotatably mounted on the frame, and the glue-applying connector and the guide pin are both vertically fixedly mounted on the fixing plate. When the connector mounting plate is in the reference docking position, the glue-applying connector and the guide pin are both distributed in the vertical direction.

[0009] As a further improvement of the present invention, the flexible mechanism includes at least two springs, a support plate is provided on the frame, the support plate is located above the back plate, and the two ends of each of the at least two springs elastically abut against the support plate and the back plate respectively; with the vertical plane where the rotation center axis of the connector mounting plate is located as the plane of symmetry, the at least two springs are symmetrically distributed with respect to this plane of symmetry.

[0010] As a further improvement of the present invention, a first limiting pin is provided on the opposite surface of the support plate and the back plate, and the two ends of the spring are respectively fitted onto the first limiting pin to form a radial limit on the end of the spring.

[0011] As a further improvement of the present invention, a waist-shaped hole is provided on the back plate, and a second limiting pin is fixed on the frame. The second limiting pin is located in the waist-shaped hole to limit the range of the joint mounting plate's swing around the rotation center axis.

[0012] As a further improvement of the present invention, a support spindle is fixed on the frame, a through hole is opened in the middle of the back plate, the support spindle is located in the through hole of the back plate, and the back plate and the support spindle are rotatably connected by a bearing.

[0013] As a further improvement of the present invention, a plurality of universal ball bearings are arranged on the top of the bracket, and each of the universal ball bearings supports the quick-change glue bucket with the rolling end facing upward, so that the quick-change glue bucket can slide freely in the horizontal direction relative to the bracket.

[0014] As a further improvement of the present invention, the quick-change glue bucket adding lifting and docking device also includes a pre-calibration mechanism, which is used to push the quick-change glue bucket supported on the universal ball bearing to move horizontally and position the quick-change glue bucket to the center position of the bracket or within the allowable deviation range of the center position.

[0015] As a further improvement of the present invention, two pre-calibration mechanisms are provided, symmetrically distributed on both sides of the quick-change glue bucket supported by the universal ball bearing, and both are driven by the lifting drive device, and can move up and down synchronously with the bracket; both pre-calibration mechanisms include a push plate and a cylinder connected to the push plate, and the two cylinders respectively drive the push plate connected to them to move in the direction facing each other, so as to form a pre-centering limit for the quick-change glue bucket, and the quick-change glue bucket can float horizontally within the allowable range.

[0016] As a further improvement of the present invention, the lifting mechanism further includes a lifting plate, which is slidably mounted on the frame in a vertical direction, and the bracket and the pre-calibration mechanism are both fixed on the lifting plate; the lifting drive device includes a ball screw transmission mechanism rotatably mounted on the frame in a vertical direction and a drive motor connected to the ball screw transmission mechanism, and the lifting plate is fixedly connected to the ball screw transmission mechanism.

[0017] The beneficial effects of this invention are: 1. This invention provides a quick-change glue bucket lifting and docking device. By setting up a lifting mechanism and a connector docking module, during the process of lifting the quick-change glue bucket upwards to complete the glue replenishment docking, the guide pin first inserts into the guide hole at the top of the quick-change glue bucket to form a guiding fit. Even if there is a deviation in the AGV's parking position, the top surface of the quick-change glue bucket is not parallel to the connector mounting plate, or the initial axis of the glue adding connector and the glue injecting connector is misaligned, the lateral force applied by the guide hole sidewall to the guide pin can also drive the connector mounting plate to adaptively swing around the rotation center axis for adjustment. At the same time, the flexible mechanism generates elastic deformation to adaptively compensate for the docking position deviation, thereby automatically correcting various position and angle deviations, guiding the glue adding connector and the glue injecting connector to align and finally achieve precise coaxial docking. It perfectly adapts to the quick-change glue supply mode where the quick-change glue bucket and AGV can be separated, effectively improving the utilization rate of AGV equipment and the continuity of glue supply in cigarette production, and meeting the production needs of automated and unmanned glue replenishment in cigarette production workshops.

[0018] 2. This invention completes the coarse alignment process of the quick-change glue bucket through a pre-calibration mechanism, which can effectively reduce the positional deviation in the subsequent docking stage, reduce the flexible compensation pressure on the joint docking module, improve docking efficiency and success rate, and avoid docking failure caused by excessive initial deviation. At the same time, two cylinders drive the corresponding push plates to move in opposite directions to form a pre-alignment limit for the quick-change glue bucket, and allow the quick-change glue bucket to float horizontally within the allowable range, retaining the horizontal floating margin of the quick-change glue bucket. Only coarse positioning is completed without locking the position of the quick-change glue bucket, leaving freedom for fine sliding alignment in the subsequent docking stage, realizing the orderly cooperation of coarse positioning and fine alignment, and taking into account both docking efficiency and docking accuracy.

[0019] 3. This invention arranges universal ball bearings on the top of the bracket to support quick-change glue buckets, allowing the glue buckets to slide freely horizontally relative to the bracket. On one hand, the pre-calibration mechanism can easily push the glue buckets to complete the pre-adjustment of their horizontal position by utilizing the low friction characteristics of the universal balls. On the other hand, when there is a horizontal position deviation during lifting and docking, the guide pin, under the lateral force of the guide hole, can push the glue buckets to slide horizontally adaptively on the universal ball bearings. This, together with the sway compensation on the joint side, forms a two-way adaptive alignment effect, significantly reducing the accuracy requirements for the initial placement position of the glue buckets. It eliminates positional deviations from both the glue bucket side and the joint side, improving the docking success rate and docking quality. Attached Figure Description

[0026] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0027] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0028] See Figures 1 to 6 The present invention provides a quick-change glue bucket adding lifting and docking device, including a frame 1, a lifting mechanism 2 and a joint docking module 4, both mounted on the frame 1.

[0029] The lifting mechanism 2 includes a bracket 21 that is slidably mounted on the frame 1 in the vertical direction and a lifting drive device connected to the bracket 21. The bracket 21 is used to support the bottom of the quick-change glue bucket 3 to be glued, and the lifting drive device is used to drive the bracket 21 to lift the quick-change glue bucket 3.

[0030] The quick-change glue tank 3 in this invention is a detachable glue tank. In one application scenario, when the intelligent glue dispensing vehicle (AGV) carrying the quick-change glue tank 3 arrives at the designated position of the glue dispensing lifting and docking device of this invention, the bracket 21 is located below the quick-change glue tank 3. The lifting drive device drives the bracket 21 to lift the quick-change glue tank 3, thereby removing the quick-change glue tank 3 from the intelligent glue dispensing vehicle. The top of the quick-change glue tank 3 is provided with a glue injection connector 31 and a guide hole 32.

[0031] Furthermore, the connector docking module 4 is installed on the top of the frame 1, above the lifting mechanism 2. The connector docking module 4 includes a flexible mechanism, a connector mounting plate 41, an adhesive-filling connector 42, and a guide pin 43. The flexible mechanism is fixedly installed on the frame 1, and the connector mounting plate 41 is rotatably installed on the frame 1, and the connector mounting plate 41 is elastically supported by the flexible mechanism. In its natural state, the connector mounting plate 41 is maintained at the reference docking position under the elastic force of the flexible mechanism. The adhesive-filling connector 42 and the guide pin 43 are both fixedly installed on the connector mounting plate 41. The guide pin 43 is used to engage with the guide hole 32 to guide the adhesive-filling connector 42 and the adhesive-filling connector 31 to dock coaxially. When there is a positional deviation between the guide pin 43 and the guide hole 32, the guide pin 43, under the lateral force of the guide hole 32, can cause the connector mounting plate 41 to swing around the rotation center axis. At the same time, the flexible mechanism generates elastic deformation to adaptively compensate for the docking position deviation.

[0032] During the process of lifting the quick-change glue tank 3 upwards by the lifting mechanism 2 to complete the glue filling and docking, the guide pin 43 first inserts into the guide hole 32 at the top of the quick-change glue tank 3 to form a guiding fit. Even if there is a deviation in the AGV's parking position, the top surface of the quick-change glue tank 3 is not parallel to the connector mounting plate 41, or the initial axis of the glue filling connector 42 and the glue injection connector 31 is misaligned, the lateral force applied by the side wall of the guide hole 32 to the guide pin 43 can drive the connector mounting plate 41 to adaptively swing and adjust around the rotation center axis. At the same time, the flexible mechanism synchronously generates elastic deformation to adaptively compensate for the docking position deviation, thereby automatically correcting various position and angle deviations and guiding the glue filling connector 42 and the glue injection connector 31. The glue joint 31 is aligned and finally achieves precise coaxial docking. This solution does not rely on the high-precision parking and positioning of the AGV, nor does it impose strict requirements on the processing and assembly precision of components such as the quick-change glue bucket 3 and the bracket 21. It can fundamentally avoid the hidden dangers of joint collision damage and glue leakage caused by rigid docking, greatly improve the docking fault tolerance and operational reliability, and perfectly adapt to the quick-change glue supply mode where the quick-change glue bucket 3 and the AGV can be separated. This allows the AGV to leave the site after placing an empty glue bucket to perform other glue supply scheduling tasks, effectively improving the utilization rate of AGV equipment and the continuity of glue supply in cigarette production, and meeting the production needs of automated and unmanned glue replenishment in cigarette production workshops.

[0033] See Figure 4 The connector mounting plate 41 is L-shaped and includes an integrally connected back plate 411 distributed vertically and a fixing plate 412 distributed horizontally. The back plate 411 is rotatably mounted on the frame 1, and the glue-applied connector 42 and guide pin 43 are both vertically fixedly mounted on the fixing plate 412. This invention sets the connector mounting plate 41 into an L-shaped structure, achieving rotatable mounting through the vertical back plate 411, while the horizontal fixing plate 412 centrally arranges the glue-applied connector 42 and guide pin 43. The overall structure is compact, and the rotation support and docking functions are clearly defined.

[0034] When the connector mounting plate 41 is in the reference docking position, the glue-applying connector 42 and the guide pin 43 are both distributed in the vertical direction, so that the guide pin 43 and the guide hole 32, and the glue-applying connector 42 and the glue-injecting connector 31 maintain the optimal docking posture, ensuring smooth alignment during the lifting and insertion process; after the glue replenishment operation is completed and the quick-change glue bucket 3 is separated from the lifting mechanism 2, the connector mounting plate 41 can automatically return to the reference docking position under the elastic restoring force of the flexible mechanism, always maintaining a stable docking reference, and ensuring the consistency of accuracy of each round of docking.

[0035] Furthermore, the connector docking module 4 also includes a ring-shaped support mandrel 48 with a flange. The support mandrel 48 is fixed to the frame 1 through its flange. A through hole is provided in the middle of the back plate 411, and the support mandrel 48 is located in the through hole of the back plate 411. The back plate 411 and the support mandrel 48 are rotatably connected by a bearing 49. This invention achieves the rotatable connection between the back plate 411 and the frame 1 through the cooperation of the support mandrel 48 and the bearing 49. The frictional resistance of the rotating pair is small, and the connector mounting plate 41 is sensitive to lateral forces. It can quickly complete adaptive yaw with the guide pin 43, and the position deviation compensation response speed is fast. At the same time, the bearing-type rotating pair structure has good rigidity and low wear. It can still maintain stable rotational accuracy under long-term high-frequency docking operations, effectively improving the durability and long-term operational reliability of the equipment.

[0036] Among them, the bearing 49 is preferably a deep groove ball bearing, and the rotation center axis of the joint mounting plate 41 described herein is also the center axis of the bearing 49.

[0037] In a preferred embodiment, two guide pins 43 are provided, with the glue-applying connector 42 located between the two guide pins 43. The lower ends of the two guide pins 43 are configured as tapered guide sections to facilitate smooth insertion into the guide holes 32 during the lifting and docking process, thereby enhancing the alignment and guiding effect. Correspondingly, the top of the quick-change glue tank 3 is provided with two guide holes 32.

[0038] In this embodiment, both the glue-adding connector 42 and the glue-injecting connector 31 are flat connectors, which are male and female connectors, respectively. After docking, they can form a sealed glue-injection channel to ensure that there is no glue leakage during the glue-adding process.

[0039] See Figures 3 to 5The flexible mechanism includes two springs 44. A support plate 45 is fixed on the frame 1, and the support plate 45 is located above the back plate 411. The two ends of each of the at least two springs 44 elastically abut against the support plate 45 and the back plate 411, respectively. With the vertical plane containing the rotation center axis of the joint mounting plate 41 as the plane of symmetry, the at least two springs 44 are symmetrically distributed relative to this plane of symmetry. This ensures that the joint mounting plate 41 is subjected to balanced forces in its natural state and is stably maintained in the reference docking position. When the joint mounting plate 41 is subjected to lateral force and sway, the springs 44 on both sides deform synchronously, and the reset force is uniform and smooth, eliminating the risk of unilateral jamming. The sway compensation process is smooth and controllable, effectively ensuring the stability and reset accuracy of the flexible docking.

[0040] It should be noted that the present invention does not limit the number of springs 44, but it must be an even number. For example, in some other embodiments of the present invention, two springs 44 may be arranged on each side of the plane of symmetry.

[0041] Furthermore, two first limiting pins 46 are protruding on the opposing surfaces of the support plate 45 and the back plate 411, and the two ends of the spring 44 are respectively fitted onto the first limiting pins 46 to form a radial limit on the ends of the spring 44, so as to prevent the spring 44 from shifting or slipping during long-term extension and contraction, and to ensure that the working position and elastic force output of the spring are always stable and reliable. This not only improves the operational stability and service life of the flexible mechanism, but also facilitates quick positioning during assembly.

[0042] Furthermore, the present invention also provides oblong holes 4111 on the back plate 411, the number of which is not limited to four, distributed around the outside of the through hole of the back plate 411. Four second limiting pins 47 are fixed on the frame 1, and the second limiting pins 47 fall into the oblong holes 4111 one by one to limit the range of the joint mounting plate 41's swing around the rotation center axis. Under the premise of ensuring sufficient position deviation compensation, it prevents the joint mounting plate 41 from swinging excessively, which could lead to mechanism failure or docking misalignment. It effectively constrains the boundary of flexible compensation and ensures the safety of the docking process and the accuracy of the reset.

[0043] It is worth mentioning that multiple universal ball bearings 22 are arranged on the top of the bracket 21. Each universal ball bearing 22 supports the quick-change glue bucket 3 with its rolling end facing upwards, allowing the quick-change glue bucket 3 to slide freely in the horizontal direction relative to the bracket 21. When there is a horizontal position deviation during the lifting and docking, the guide pin 43, under the lateral force of the guide hole 32, can push the quick-change glue bucket 3 to slide adaptively horizontally on the universal ball bearing 22. This, together with the runout compensation on the joint side, forms a two-way adaptive alignment effect, significantly reducing the accuracy requirements for the initial placement position of the quick-change glue bucket 3. It eliminates positional deviations from both the glue bucket side and the joint side, improving the docking success rate and docking quality.

[0044] See Figure 3 and Figure 6 The lifting mechanism 2 also includes a lifting plate 23. A slide rail is fixed vertically on the frame 1, and the lifting plate 23 is slidably connected to the slide rail via a slider. Two brackets 21 are provided, fixed side-by-side at intervals on the front side of the lifting plate 23, and are perpendicular to the lifting plate 23. The lifting drive device includes a ball screw transmission mechanism 24, a drive motor 25, and a reducer. The ball screw transmission mechanism 24 is rotatably mounted on the frame 1 in the vertical direction. The drive motor 25 is preferably a servo motor, which is driven and connected to the ball screw transmission mechanism 24 through the reducer. The lifting plate 23 is fixedly connected to the lead screw nut in the ball screw transmission mechanism 24. The drive motor 25 drives the ball screw transmission mechanism 24 to rotate through the reducer, and the rotational motion is converted into vertical up-and-down motion through the lead screw nut, so as to drive the lifting plate 23 and the brackets 21 mounted on the lifting plate 23 to perform lifting motion.

[0045] In addition, the quick-change glue bucket adding and lifting docking device of the present invention also includes a pre-calibration mechanism 5, which is used to push the quick-change glue bucket 3 supported on the universal ball bearing 22 to move horizontally, positioning the quick-change glue bucket 3 to the center position of the bracket 21 or within the allowable deviation range of the center position, completing the rough alignment process. This can effectively reduce the positional deviation in the subsequent docking stage, reduce the flexible compensation pressure of the joint docking module 4, improve docking efficiency and docking success rate, and avoid docking failure caused by excessive initial deviation.

[0046] like Figure 6 As shown, there are two pre-calibration mechanisms 5, both fixed on the lifting plate 23 and symmetrically distributed on both sides of the quick-change rubber bucket 3 supported by the universal ball bearing 22. Both are driven by the lifting drive device and can move up and down synchronously with the bracket 21.

[0047] Specifically, both pre-calibration mechanisms include a push plate 51 and a cylinder 52. A mounting bracket is provided on the lifting plate 23. The push plate 51 is slidably connected to the mounting bracket through a guide rail pair. The cylinder 52 is fixed on the mounting bracket and driven to the push plate 51.

[0048] Furthermore, multiple rubber blocks 53 are installed on the sides of the two push plates 51 facing each other for flexible contact with the quick-change glue tank 3. Some of the rubber blocks 53 are distributed opposite to the left and right sides of the quick-change glue tank 3, while others are inclined and distributed opposite to the left and right edges of the front side of the quick-change glue tank 3. The rubber blocks 53 and the lifting plate 23 can limit the quick-change glue tank 3 in the front-back and left-right horizontal directions.

[0049] Two cylinders 52 are used to drive their respective connected push plates 51 to move towards each other, so as to pre-align and limit the quick-change rubber bucket 3. In the pre-alignment and limit state, some rubber blocks 53 are left with gaps between them and the quick-change rubber bucket 3, so as to retain the horizontal floating margin of the quick-change rubber bucket 3. Only coarse positioning is completed without locking the position of the quick-change rubber bucket 3, so that the quick-change rubber bucket 3 can float horizontally within the allowable range, which retains the degree of freedom for fine sliding and alignment in the subsequent docking stage, and realizes the orderly cooperation of coarse positioning and fine alignment, taking into account docking efficiency and docking accuracy.

[0050] The pre-calibration mechanism 5 can easily push the quick-change rubber bucket 3 to complete the pre-adjustment of its horizontal position by taking advantage of the low friction characteristics of the universal ball bearing 22.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
