Abstract
Description
Technical Field
[0001] This invention belongs to the field of fireworks production technology, and in particular relates to an automatic assembly device for hand-operated salute cannons. Background Technology
[0002] Hand-operated ceremonial cannons are a common festive item used in celebrations and festivals. Their ease of operation and excellent atmosphere-creating effect have led to a continuous increase in market demand. Their structure mainly includes core components such as the shell, trigger, base, ribbons, and top cover. The assembly process requires multiple steps, including component positioning, assembly, and fixing, demanding high precision and seamless workflow.
[0003] Currently, the production and assembly of hand-operated ceremonial cannons still largely rely on traditional manual operation or semi-automated equipment. In the traditional manual assembly model, workers must manually complete a series of repetitive tasks such as sorting, positioning, assembling, and securing parts. This is not only labor-intensive and costly, but also suffers from significant efficiency bottlenecks. A single production line requires multiple workers to work collaboratively, limiting single-shift capacity. Furthermore, factors such as worker skill level and fatigue contribute to poor product assembly consistency, leading to quality issues like misaligned cannon pins, insecurely fixed bases, and uneven ribbon filling, resulting in significant fluctuations in product qualification rates. Simultaneously, the sorting and precise alignment of small parts involved in manual operation are difficult to control efficiently and stably through manual labor, further restricting the expansion of production scale.
[0004] To address these issues, some companies have begun introducing semi-automated assembly equipment, replacing manual labor with mechanized single-process operations. For example, they use independent drilling machines and die-casting assembly machines to complete specific tasks. However, existing semi-automated equipment still has significant drawbacks: each process is independent, requiring manual material transfer and connection between processes, failing to form a fully automated closed loop and resulting in limited improvements in production efficiency; the equipment lacks a unified collaborative control system, making it difficult to achieve precise matching of assembly accuracy at each stage, still requiring manual calibration, which is time-consuming, labor-intensive, and leads to low production efficiency.
[0005] Therefore, how to provide a hand-operated cannon assembly equipment that can achieve automated assembly, high assembly accuracy, and high efficiency is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0006] To solve at least one of the above-mentioned technical problems, the present invention provides an automatic assembly device for hand-operated salute cannons, comprising: frame; The outer cylinder feeding mechanism, mounted on the frame, is used to provide and transport the outer cylinder; The capping and feeding mechanism, mounted on the frame, is used to provide and convey caps; The threading mechanism, located near the cap feeding mechanism, is used to insert the pull wire into the cap; The capping mechanism is mounted on the frame and connected to the discharge end of the capping and feeding mechanism. It is used to receive and position the caps. The capping and transfer mechanism is installed on the frame and located between the outer cylinder feeding mechanism and the capping mechanism. The capping and transfer mechanism is used to grab the outer cylinder from the discharge end of the outer cylinder feeding mechanism and transfer the outer cylinder to the positioning station of the capping mechanism. The capping and transfer mechanism can drive the outer cylinder to rotate around its own axis so that the outer cylinder and the capping mechanism can be assembled and fixed with the positioning cap thread on the capping mechanism. The folding mechanism is set on the frame and located on the side of the cap screwing mechanism away from the cap feeding mechanism. It is used to fold the pull wire on the hand-pulled salute cannon after the cap and outer cylinder assembly is completed to the outer surface of the outer cylinder. The tape preparation mechanism is located on the side of the folding mechanism opposite to the capping mechanism and is used to provide and transport tape. The adhesive applicator is located on the side of the capping and transfer mechanism away from the outer cylinder feeding mechanism, between the capping mechanism and the folding mechanism. The adhesive applicator and the capping and transfer mechanism work synchronously and in the same direction. The adhesive applicator is used to pick up the hand-held salute cannon that has been sealed and assembled with the outer cylinder from the capping mechanism, transfer the hand-held salute cannon to the folding mechanism for folding, and receive the tape conveyed by the adhesive preparation mechanism. By driving the hand-held salute cannon to rotate around its own axis, the tape fixes the folded line segment of the hand-held salute cannon to the outer surface of the outer cylinder.
[0007] Furthermore, the outer cylinder feeding mechanism includes a first vibratory plate for sorting and feeding materials to the outer cylinder, and a first linear feeder connected to the discharge end of the first vibratory plate for linear conveying of the outer cylinder. The outer cylinder feeding mechanism also includes an outer cylinder separating component, which is located at the end of the first linear feeder away from the first vibrating plate. The outer cylinder separating component is used to push out the outer cylinder on the first linear feeder so that the capping and transfer mechanism can clamp the pushed-out outer cylinder. The capping and feeding mechanism includes a second vibratory plate for capping and sorting feeding, and a second linear feeder connected to the discharge end of the second vibratory plate for linear conveying of the caps. The discharge end of the second linear feeder is connected to the capping mechanism and is used to deliver the cap to the capping mechanism.
[0008] Furthermore, the threading mechanism includes: The guide cylinder is located on the side of the second linear feeder away from the frame and is positioned corresponding to the cover. It is used to guide the pull wire into the cover. The traction component is located on the side of the second linear feeder near the frame, corresponding to the guide cylinder, and is used to pull the cable and pull the head of one end of the cable into the cover.
[0009] Furthermore, the frame is provided with a first slide rail and a first slide plate that is slidably connected to the first slide rail; The first slide plate is used to drive the capping and transfer mechanism to reciprocate between the outer cylinder feeding mechanism and the capping mechanism along the first slide rail, and to simultaneously drive the adhesive applicator to reciprocate between the capping mechanism and the folding mechanism along the first slide rail. The capping and transfer mechanism and the cap screwing mechanism are both slidably connected to the first slide plate, which can drive the capping and transfer mechanism to move synchronously closer to or away from the frame.
[0010] Furthermore, the capping and transferring mechanism is assembled from top to bottom in the vertical direction with a first servo motor, a first coupling, a first rotating shaft, a first pneumatic slip ring, a first mounting plate, a spring, a capping sleeve, a connecting plate, and a first pneumatic clamp. The output end of the first servo motor is connected to the first rotating shaft via the first coupling to drive the first rotating shaft to rotate around the vertical axis; the first pneumatic slip ring is sleeved on the outside of the first rotating shaft to realize the rotational connection between the air circuit and the circuit of the first pneumatic clamp and avoid the tangling of the pipeline. The capping sleeve is connected to the end of the first rotating shaft away from the first servo motor, and the capping sleeve can slide axially along the first rotating shaft. The end of the first pneumatic slip ring sleeve away from the first servo motor is provided with a first mounting plate. The spring is sleeved on the part of the first rotating shaft located between the capping sleeve and the first mounting plate, and the two ends of the spring abut against the end face of the first mounting plate and the end face of the capping sleeve, respectively. Initially, the spring is in a compressed state, which is used to provide axial pressure during the capping process and to compensate for the axial displacement generated during the capping process so that the outer cylinder is aligned with the center of the capping shaft. The end of the cap sleeve away from the spring is fixedly connected to the connecting plate. The first pneumatic clamp is installed on the connecting plate and is used to open and close the outer cylinder. It is driven by the first servo motor to drive the outer cylinder to rotate synchronously, thus completing the assembly of the outer cylinder and the cap.
[0011] Furthermore, the capping mechanism includes a feeding channel, a second slide rail, a second sliding plate, a transfer positioning clamp, and a fixing block; The feed end of the feeding channel is connected to the discharge end of the second linear feeder, which is used to receive and transport the caps, so that the caps move directionally along the channel to the gripping station; The second slide rail is perpendicular to the feeding channel, with one end corresponding to the discharge end of the feeding channel and the other end corresponding to the fixing block; the second slide plate is slidably mounted on the second slide rail, and the transfer positioning clamp is set on the second slide plate and can move back and forth along the second slide rail with the second slide plate to grab the cap from the discharge end of the feeding channel and transfer the cap to the positioning station where the fixing block is located. The fixed block is located on the side of the feeding channel near the capping and transfer mechanism. When the transfer positioning clamp moves the cap to the positioning station corresponding to the fixed block, the transfer positioning clamp and the fixed block work together to clamp and position the cap, so that the cap and the outer cylinder clamped by the capping and transfer mechanism remain coaxial and fixed.
[0012] Furthermore, the cap-tightening mechanism includes a baffle mounted on the second slide plate, which can reciprocate along the second slide rail with the second slide plate; The end of the baffle away from the transfer positioning clamp is the material blocking end. When the second slide plate drives the transfer positioning clamp and the baffle to the initial position, the material blocking end blocks the outlet of the feeding channel, preventing the cover from coming off from the feeding channel. An arc-shaped groove is provided on the baffle. The position of the arc-shaped groove is vertically aligned with the clamping center of the transfer positioning clamp. The curvature of the arc-shaped groove matches the outer contour of the cover. When the second slide plate slides along the second slide rail toward the feeding channel, it drives the transfer positioning clamp and the baffle to move synchronously, so that the arc-shaped groove is connected to the discharge end of the feeding channel. The cover in the feeding channel falls into the arc-shaped groove to achieve positioning. The transfer positioning clamp closes and clamps the cover in the arc-shaped groove and transfers it.
[0013] Furthermore, the adhesive applicator is equipped with a second servo motor, a second coupling, a second rotating shaft, a second pneumatic slip ring, a second mounting plate, and a second pneumatic clamp in the vertical direction from top to bottom. The output end of the second servo motor is connected to the second rotating shaft via the second coupling to drive the second rotating shaft to rotate around the vertical axis; the second pneumatic slip ring is sleeved on the outside of the second rotating shaft to realize the rotational connection between the air circuit and the circuit of the second pneumatic clamp and avoid the tangling of the pipeline. The second pneumatic slip ring sleeve has a second mounting plate at the end away from the second servo motor. The second pneumatic clamp is mounted on the second mounting plate and is used to open and close the outer cylinder after the cap assembly is completed and move it to the folding mechanism for folding. It also drives the outer cylinder to rotate synchronously with the second servo motor to complete the adhesive application.
[0014] Furthermore, the broken line mechanism includes: The guide clamp has a limiting hole. The guide clamp is used to clamp the pull wire and keep the pull wire in the limiting hole to guide the pull wire. The folding assembly is located on the side of the guide clamp away from the capping mechanism. It includes a drive unit and a folding shaft. The folding shaft is aligned with the pull line segment of the guide clamp near the adhesive applicator and is used to fold part of the pull line to the outer surface of the outer cylinder. The drive unit is used to drive the folding shaft to move so that the folding shaft picks up the pull line to the outer surface of the outer cylinder.
[0015] Furthermore, the glue preparation mechanism includes a film roll holder, guide wheels, fixing clamps, glue pulling clamps, a cutter, and a vacuum glue suction component; The film roll holder carries a roll of tape. Guide rollers are located on the discharge side of the film roll holder to guide the tape conveying direction, so that the tape extends along the preset path to the fixed clamp. The fixing clamp is used to clamp the starting end of the tape, and the pulling clamp is located on the side of the fixing clamp away from the guide wheel. It is used to grab the free end of the tape and pull it along the extension direction of the tape to make the tape unfold to the preset length. The cutter is positioned between the fixing clamp and the adhesive pulling clamp. When the adhesive pulling clamp pulls the tape to a preset length, the cutter cuts the tape to form a single-segment formed tape. The vacuum adhesive suction unit is located between the folding mechanism and the shearing station of the cutter, and can reciprocate between the folding mechanism and the shearing station of the cutter. It is used to absorb the shaped adhesive tape after shearing, transfer the shaped adhesive tape from the shearing station to the folding mechanism, and work together with the adhesive applicator located at the folding mechanism to complete the adhesive applicator operation.
[0016] This invention provides an automatic assembly device for hand-operated salute cannons, comprising a frame, an outer cylinder feeding mechanism, a cap feeding mechanism, a threading mechanism, a cap screwing mechanism, a cap transfer mechanism, a folding mechanism, an adhesive preparation mechanism, and an adhesive application mechanism. The outer cylinder feeding mechanism and the cap feeding mechanism respectively provide the outer cylinder and the cap, and the threading mechanism inserts a pull wire into the cap. The cap screwing mechanism receives and positions the cap. The cap transfer mechanism transfers the outer cylinder to the positioning position of the cap screwing mechanism and drives the outer cylinder to rotate around its own axis, so that the outer cylinder mates with the cap threaded on the cap screwing mechanism for assembly and fixation. This achieves full automation of the feeding, positioning, and screwing assembly process, significantly improving production efficiency. The capping and transfer mechanism automates the gripping and transfer of the outer cylinder, and works in conjunction with the capping fixture for precise cap positioning. No manual intervention is required for material transfer and alignment between processes. Furthermore, the capping and transfer mechanism can directly drive the outer cylinder to rotate and complete the screw-on assembly, integrating the assembly process of the outer cylinder and the cap into an automated closed-loop operation. This effectively eliminates the efficiency bottleneck of manual operation, significantly improves the overall assembly efficiency, and greatly enhances the assembly accuracy, ensuring the consistency of product assembly. The folding mechanism folds the pull line on the hand-held salute cannon, which has completed the capping and outer cylinder assembly, to the outer surface of the outer cylinder; the glue preparation mechanism provides and conveys adhesive tape; the adhesive application mechanism picks up the hand-held salute cannon, which has completed the capping and outer cylinder assembly, from the capping mechanism, transfers the hand-held salute cannon to the folding mechanism for folding, and receives the adhesive tape conveyed by the glue preparation mechanism. By driving the hand-held salute cannon to rotate around its own axis, the adhesive tape fixes the folded line segment of the hand-held salute cannon to the outer surface of the outer cylinder. The adhesive application mechanism and the capping and transfer mechanism are synchronized and move in the same direction. Its structure is compact and tightly connected, eliminating waiting gaps between processes, greatly improving the overall assembly efficiency, simplifying the overall structure of the equipment for easy operation, and having a high degree of automation, making it suitable for the equipment use needs of large-scale production.

[0022] like Figure 1 and Figure 2 As shown, the present invention provides an automatic assembly device 100 for hand-pulled salute cannons. The automatic assembly device 100 for hand-pulled salute cannons includes a frame 110, an outer cylinder feeding mechanism 120, a cap feeding mechanism 130, a threading mechanism 140, a cap screwing mechanism 150, a cap rotating and transferring mechanism 160, a folding mechanism 180, an adhesive preparation mechanism 190, and an adhesive application mechanism 170.
[0023] The outer cylinder feeding mechanism, the cap feeding mechanism, the threading mechanism, the cap screwing mechanism, the cap transfer mechanism, the folding mechanism, the glue preparation mechanism, and the glue application mechanism are all mounted on the machine frame.
[0024] Specifically, the outer cylinder feeding mechanism is used to provide and transport the outer cylinder. The cap feeding mechanism is used to provide and transport the cap. The threading mechanism is located near the cap feeding mechanism and is used to insert the pull wire into the cap. The cap screwing mechanism is connected to the discharge end of the cap feeding mechanism and is used to receive and position the cap.
[0025] In addition, the capping and transfer mechanism is located between the outer cylinder feeding mechanism and the capping mechanism. The capping and transfer mechanism is used to grab the outer cylinder from the discharge end of the outer cylinder feeding mechanism and transfer the outer cylinder to the positioning station of the capping mechanism. The capping and transfer mechanism can drive the outer cylinder to rotate around its own axis so that the outer cylinder and the capping mechanism can be assembled and fixed with the positioning cap thread.
[0026] The folding mechanism is located on the side of the cap-screwing mechanism opposite to the cap-feeding mechanism. It folds the pull line on the hand-held ceremonial cannon, after the cap and outer cylinder assembly is completed, to the outer surface of the outer cylinder. The adhesive preparation mechanism is located on the side of the folding mechanism opposite to the cap-screwing mechanism and provides and conveys adhesive tape. The adhesive applicator is located on the side of the cap-screwing and transfer mechanism opposite to the outer cylinder feeding mechanism, between the cap-screwing and folding mechanisms, and moves synchronously and in the same direction as the cap-screwing and transfer mechanisms. It is used to grab the hand-held ceremonial cannon after the cap and outer cylinder assembly is completed from the cap-screwing mechanism, transfer the hand-held ceremonial cannon to the folding mechanism for folding, and receive the adhesive tape conveyed by the adhesive preparation mechanism. By driving the hand-held ceremonial cannon to rotate around its own axis, the adhesive tape fixes the folded line segment of the hand-held ceremonial cannon to the outer surface of the outer cylinder.
[0027] In this embodiment, the automatic assembly equipment 100 for hand-operated salute cannons of the present invention includes a frame, an outer cylinder feeding mechanism, a cap feeding mechanism, a threading mechanism, a cap screwing mechanism, a cap transfer mechanism, a folding mechanism, a glue preparation mechanism, and a glue application mechanism. The outer cylinder feeding mechanism and the cap feeding mechanism respectively provide the outer cylinder and the cap, and the threading mechanism inserts a pull wire into the cap, thus achieving directional material conveying. The cap screwing mechanism positions and fixes the cap, transferring it to the outer cylinder of the cap screwing mechanism for vertical coaxiality. The cap transfer mechanism then drives the outer cylinder to rotate around its own axis, assembling and fixing the outer cylinder with the cap threadedly positioned on the cap screwing mechanism. Therefore, the automatic assembly equipment for hand-operated salute cannons in this embodiment achieves full automation of the feeding, positioning, and screwing assembly process, significantly improving production efficiency. In this embodiment, the capping and transfer mechanism completes the automated gripping and transfer of the outer cylinder, and with the precise positioning of the capping fixture, there is no need for manual intervention in material transfer and alignment between processes. Moreover, the capping and transfer mechanism can directly drive the outer cylinder to rotate to complete the screw-on assembly, integrating the assembly process of the outer cylinder and the cap into an automated closed-loop operation, effectively eliminating the efficiency bottleneck of manual operation, significantly improving the overall assembly efficiency, greatly improving the assembly accuracy, and ensuring the consistency of product assembly. In addition, in this embodiment, a folding mechanism folds the pull line on the hand-held ceremonial cannon, after the cap and outer cylinder assembly are completed, to the outer surface of the outer cylinder. A glue preparation mechanism provides and conveys adhesive tape, and a glue-applying mechanism picks up the hand-held ceremonial cannon from the cap-screwing mechanism after the cap and outer cylinder assembly is completed, transferring the cannon to the folding mechanism for folding. The mechanism also receives adhesive tape from the glue preparation mechanism and, by rotating the hand-held ceremonial cannon around its own axis, fixes the folded line segment of the cannon to the outer surface of the outer cylinder with adhesive tape. The glue-applying mechanism and the cap-screwing and transfer mechanism work synchronously and in the same direction. The assembly equipment in this embodiment has a compact structure, tight connections, eliminates waiting gaps between processes, and significantly improves overall assembly efficiency. Through the collaborative cooperation of various mechanisms, this embodiment further improves the automation level and efficiency of hand-held ceremonial cannon production, reduces labor costs, and is suitable for large-scale production.
[0028] Optionally, such as Figure 2 and Figure 3 As shown, the outer cylinder feeding mechanism 120 includes a first vibratory feeder 121 for sorting and feeding outer cylinders, and a first linear feeder 122 connected to the discharge end of the first vibratory feeder for linear conveying of the outer cylinders. Additionally, the outer cylinder feeding mechanism also includes an outer cylinder separating component 123, located at the end of the first linear feeder away from the first vibratory feeder, and on the side of the first linear feeder closer to the frame. The outer cylinder separating component pushes out the corresponding outer cylinder by penetrating the bottom of the first linear feeder, thus facilitating the capping and transfer mechanism to clamp the pushed-out outer cylinder. Preferably, in this embodiment, the outer cylinder separating component is, for example, a combination of a cylinder and a top block.
[0029] In this embodiment, the outer cylinder is automatically oriented and sorted by the first vibratory feeder, and then enters the first linear feeder in an orderly manner. The first linear feeder then accurately conveys the orderly material output by the first vibratory feeder to the target station in a straight line, which is the location corresponding to the material distribution component of the outer cylinder.
[0030] In addition, such as Figure 2 As shown, the capping and feeding mechanism 130 includes a second vibratory feeder 131 for capping and sorting feeding, and a second linear feeder 132 connected to the discharge end of the second vibratory feeder for linear conveying of caps. The discharge end of the second linear feeder is connected to the capping mechanism and is used to feed caps to the capping mechanism.
[0031] Optionally, such as Figure 11 As shown, the threading mechanism 140 includes a guide cylinder 141 and a traction member 142. The guide cylinder is fixedly disposed on the side of the second linear feeder away from the frame and is correspondingly disposed to the cover, for guiding the pull wire into the cover. The traction member is disposed on the side of the second linear feeder close to the frame and is correspondingly disposed to the guide cylinder, for pulling the pull wire and pulling the head of one end of the pull wire into the cover.
[0032] Specifically, in this embodiment, the guide cylinder has a funnel-shaped through hole. By inserting the end of the pull cable with the cannon head facing upwards and the other end of the pull cable through the through hole of the guide cylinder, the pull cable is inserted into the cover through the through hole. Optionally, the traction component in this embodiment includes a traction clamp and a traction cylinder. The traction cylinder is mounted on the frame, and the traction clamp is fixedly connected to the traction cylinder. The traction clamp is correspondingly arranged with the guide cylinder. The traction clamp is used to grip the pull cable passing through the cover. The traction cylinder can drive the traction clamp to move closer to or away from the frame to pull the cannon head at the upper end of the pull cable into the cover. Preferably, the traction clamp in this embodiment is, for example, a combination of a pneumatic finger and a pair of clamping blocks.
[0033] Optionally, such as Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the adhesive application mechanism 170 and the capping and transfer mechanism 160 are synchronously linked in the same direction. The frame is equipped with a first slide rail 111 and a first sliding plate 112 slidably connected to the first slide rail. The first sliding plate drives the capping and transfer mechanism to reciprocate along the first slide rail between the outer cylinder feeding mechanism and the capping mechanism, and synchronously drives the adhesive application mechanism to reciprocate along the first slide rail between the capping mechanism and the folding mechanism. Optionally, in this embodiment, a telescopic cylinder drives the first sliding plate to move along the first slide rail, thereby driving the capping and transfer mechanism and the capping mechanism to move along the first slide rail.
[0034] Furthermore, both the capping and transferring mechanism and the cap-tightening mechanism are slidably connected to the first sliding plate. The first sliding plate can drive the capping and transferring mechanism to move synchronously closer to or away from the frame, thus achieving synchronous up-and-down movement of the capping and transferring mechanism and the cap-tightening mechanism. Specifically, the capping and transferring mechanism and the cap-tightening mechanism are mounted on the same mounting base 113, which is slidably connected to the first sliding plate, allowing the capping and transferring mechanism to move up and down along the first sliding plate. Optionally, in this embodiment, a telescopic cylinder drives the mounting base to move closer to or away from the frame along the first sliding plate, thereby driving the capping and transferring mechanism to move closer to or away from the frame and up and down.
[0035] It should be noted that in this embodiment, the distance between the adhesive application mechanism and the capping and transfer mechanism, the distance from the discharge end of the outer cylinder feeding mechanism to the capping mechanism, and the distance from the capping mechanism to the folding mechanism are all the same. Combined with the synchronous and unidirectional linkage mechanism of the adhesive application mechanism and the capping and transfer mechanism, it is possible to achieve the following: when the capping and transfer mechanism reaches the discharge end of the outer cylinder feeding mechanism to clamp the outer cylinder, the adhesive application mechanism also reaches the capping mechanism to clamp the outer cylinder that has completed the capping assembly; and when the capping and transfer mechanism moves the outer cylinder to the capping mechanism, the adhesive application mechanism also clamps the outer cylinder that has completed the capping assembly and reaches the folding mechanism, thereby further improving the overall assembly efficiency.
[0036] Optionally, such as Figure 4 As shown, the capping and transferring mechanism is assembled from top to bottom in the vertical direction as follows: a first servo motor 161, a first coupling 162, a first rotating shaft 163, a first pneumatic slip ring 164, a first mounting plate 1611, a spring 166, a capping sleeve 167, a connecting plate 168, and a first pneumatic clamp 169.
[0037] The output end of the first servo motor is connected to the first rotating shaft via a first coupling, driving the first rotating shaft to rotate around a vertical axis. A first pneumatic slip ring is sleeved on the outside of the first rotating shaft to achieve rotational connection between the air path and the electrical circuit of the first pneumatic clamp, preventing pipeline entanglement. Specifically, the capping and transfer mechanism in this embodiment also includes a first slip ring sleeve 1641, which is sleeved on the outer surface of the first pneumatic slip ring to protect it.
[0038] Specifically, the capping sleeve is fitted onto the end of the first rotating shaft away from the first servo motor and is connected to the first rotating shaft in a driving connection, and the capping sleeve can slide axially along the first rotating shaft. Optionally, in this embodiment, the capping sleeve is connected to the rotating shaft in a driving connection via a pin, and slides within a waist-shaped groove on the inner wall of the capping sleeve via the pin, so that the capping sleeve can slide axially along the first rotating shaft, thereby realizing the axial up-and-down floating of the capping device during the capping process.
[0039] Additionally, a first mounting plate is provided at the end of the first pneumatic slip ring sleeve furthest from the first servo motor. A spring is sleeved on the first rotating shaft between the capping sleeve and the first mounting plate, with both ends of the spring abutting the end faces of the first mounting plate and the capping sleeve, respectively. Initially, the spring is in a compressed state, used to provide axial pressure during the capping process and to compensate for axial displacement generated during the capping process, so as to align the outer cylinder with the center of the capping shaft.
[0040] Specifically, the end of the cap sleeve away from the spring is fixedly connected to the connecting plate. The first pneumatic clamp is mounted on the connecting plate and is used to open and close the outer cylinder. Driven by the first servo motor, it drives the outer cylinder to rotate synchronously, completing the assembly of the outer cylinder and the cap. Preferably, in this embodiment, the first pneumatic clamp is, for example, a combination structure of a pneumatic finger and a pair of clamping blocks.
[0041] Optionally, such as Figure 7 and Figure 8 As shown, the capping mechanism in this embodiment includes a feeding channel 151, a second slide rail 155, a second slide plate 154, a transfer positioning clamp 152, a baffle 156, and a fixing block 153.
[0042] The feeding channel's inlet end is connected to the outlet end of the second linear feeder, used to receive and transport the caps, allowing them to move directionally along the channel to the gripping station. Additionally, a second slide rail is mounted on the frame, perpendicular to the feeding channel, with one end corresponding to the outlet end of the feeding channel and the other end corresponding to the fixed block. Specifically, a second sliding plate is slidably mounted on the second slide rail, and a transfer positioning clamp is mounted on the second sliding plate and can reciprocate along the second slide rail with the second sliding plate. The transfer positioning clamp is used to grip the caps from the outlet end of the feeding channel and transfer them to the positioning station where the fixed block is located.
[0043] Optionally, the baffle is mounted on the second slide plate and can reciprocate along the second slide rail with the second slide plate. The end of the baffle away from the transfer positioning clamp is the material blocking end. When the second slide plate moves the transfer positioning clamp and the baffle to the initial position, the material blocking end blocks the outlet of the feeding channel, preventing the cover from falling out of the feeding channel.
[0044] In addition, an arc-shaped groove is provided on the baffle. The position of the arc-shaped groove is vertically aligned with the clamping center of the transfer positioning clamp. The curvature of the arc-shaped groove is adapted to the outer periphery of the cover. When the second slide plate slides along the second slide rail toward the feeding channel, it drives the transfer positioning clamp and the baffle to move synchronously, so that the arc-shaped groove is connected to the discharge end of the feeding channel. The cover in the feeding channel falls into the arc-shaped groove to achieve positioning. The transfer positioning clamp closes and clamps the cover in the arc-shaped groove and transfers it.
[0045] Specifically, the fixing block is located on the side of the feeding channel near the capping and transfer mechanism. When the transfer positioning clamp moves the cap to the positioning station corresponding to the fixing block, the fixing block is positioned opposite to the arc groove on the baffle. The transfer positioning clamp still holds the cap, aligning its axis with the outer cylinder held on the capping and transfer mechanism. The fixing block pushes the cap towards the baffle to fix it. The transfer positioning clamp and the fixing block work together to clamp and position the cap, keeping the cap and the outer cylinder held by the capping and transfer mechanism coaxial and fixed, and working together with the capping and transfer mechanism to complete the assembly of the outer cylinder and the cap.
[0046] Optionally, in this embodiment, the fixed block is driven by a cylinder to push the cover in the arc-shaped groove towards the baffle. In this embodiment, one end of the fixed block that pushes the cover can be configured to match the shape of the outer surface of the cover, such as an arc-shaped groove.
[0047] Optionally, such as Figure 4 and Figure 5 As shown, the adhesive applicator 170 is equipped with a second servo motor 171, a second coupling 172, a second rotating shaft 173, a second pneumatic slip ring 175, a second mounting plate 176, and a second pneumatic clamp 177 in sequence from top to bottom along the vertical direction.
[0048] The output end of the second servo motor is connected to the second rotating shaft via a second coupling, driving the second rotating shaft to rotate around a vertical axis. A second pneumatic slip ring is fitted onto the outside of the second rotating shaft to ensure rotational connection between the air path and electrical circuit of the second pneumatic clamp, preventing tubing entanglement. Specifically, the adhesive applicator in this embodiment also includes a second slip ring sleeve 174, which is fitted onto the outer surface of the second pneumatic slip ring to protect it.
[0049] Specifically, the adhesive application mechanism also includes a second mounting bracket 178, wherein the second servo motor and the second slip ring sleeve are both mounted on the second mounting bracket, and the second slip ring sleeve and the second rotating shaft are connected by bearing support. In this embodiment, the entire adhesive application mechanism is fixed to the mounting base by the second mounting bracket.
[0050] Additionally, a second mounting plate 176 is provided at the end of the second pneumatic slip ring sleeve furthest from the second servo motor. The second pneumatic clamp is mounted on the second mounting plate and is used to open and close the outer cylinder after the cap assembly is completed, move it to the folding mechanism for folding processing, and drive the outer cylinder to rotate synchronously in both directions by a preset angle with the drive of the second servo motor to complete the adhesive application. Optionally, the preset angle ranges from 180° to 190°, specifically, for example, 180°, 185°, or 190°.
[0051] Optionally, such as Figure 3 and Figure 9As shown, the folding mechanism includes a guide clamp 181 and a folding assembly 182. The guide clamp has a limiting hole for clamping the pull wire and positioning it within the limiting hole to guide its alignment. The folding assembly is located on the side of the guide clamp opposite to the capping mechanism and includes a drive unit and a folding shaft 1821. The folding shaft is aligned with the pull wire segment of the guide clamp near the adhesive applicator and is used to fold a portion of the pull wire to the outer surface of the outer cylinder. The drive unit drives the folding shaft to move, causing it to lift the pull wire to the outer surface of the outer cylinder. Preferably, the guide clamp is, for example, a combination of a pneumatic finger and a pair of clamping blocks.
[0052] Among them, such as Figure 9 As shown, the drive unit in this embodiment includes a third slide rail 1826, a third slide plate 1825, a radial drive cylinder 1824, a micro cylinder 1823, and a bushing 1822. The third slide rail is vertically mounted on the machine frame table via a plate, meaning the third slide rail is vertically positioned and faces the alignment clamp. The third slide plate is slidably mounted on the third slide rail, and the radial drive cylinder is located on the side of the third slide plate away from the third slide rail. The micro cylinder is mounted on the telescopic end of the radial drive cylinder via a plate, and the bushing is located on the telescopic end of the micro cylinder, facing the alignment clamp. The bushing is used to mount a zigzag shaft, the axis of which is perpendicular to the axis of the pull line guided by the alignment clamp. The micro cylinder drives the bushing and the zigzag shaft to move closer to or away from the alignment clamp, and the radial drive cylinder drives the micro cylinder, the drive bushing, and the zigzag shaft to move radially away from the alignment clamp along the pull line of the alignment clamp.
[0053] In this embodiment, when the adhesive applicator clamps the hand-pulled salute cannon, which is assembled with the cap and outer cylinder, to the folding mechanism station, the guide clamp holds the pull line of the hand-pulled salute cannon so that it is located in the limiting hole formed by the clamping and guides the pull line. The folding axis is perpendicular to the pull line held by the guide clamp. The micro cylinder drives the folding axis to press against the side of the pull line close to the guide clamp and make the folding axis tangent to the pull line. The radial drive cylinder moves the folding axis away from the guide clamp. At this time, the folding axis lifts the pull line and then slides upward toward the adhesive applicator on the third slide rail through the third slider, so that the folding axis carries the pull line to the outer surface of the outer cylinder. Under its own weight, the pull line forms a folded double line and is tightly attached to the outer surface of the outer cylinder.
[0054] It should be noted that the frame in this embodiment is provided with a discharge port 114 at the position corresponding to the guide clamp, which is used to collect the assembled hand-pulled salute cannons.
[0055] Optionally, such as Figure 3 , Figure 10 and Figure 12 As shown, the glue preparation mechanism in this embodiment includes a glue roll holder 191, a guide wheel 192, a fixing clamp 193, a glue pulling clamp 195, a cutter 194, and a vacuum glue suction component 196.
[0056] The film roll holder carries a roll of adhesive tape. Guide rollers are located on the discharge side of the film roll holder to guide the tape's conveying direction, allowing the tape to extend along a preset path to the fixing clamp. The fixing clamp secures the starting end of the tape, while a pull clamp is located on the side of the fixing clamp opposite to the guide rollers. This pull clamp grips the free end of the tape and pulls it along the tape's extension direction, unfolding the tape to a preset length. A cutter is positioned between the fixing clamp and the pull clamp. When the pull clamp pulls the tape to the preset length, the cutter cuts the tape, forming a single-segment formed tape. In this embodiment, both the fixing clamp and the pull clamp are, for example, a combination of pneumatic fingers and a pair of clamping blocks, and the cutter is driven by a cylinder to cut the tape.
[0057] Optionally, in this embodiment, the adhesive preparation mechanism further includes an adhesive pulling cylinder 198, which is connected to the adhesive pulling clamp and is used to drive the adhesive pulling clamp to approach or move away from the fixing clamp, grab the free end of the tape and pull it along the extension direction of the tape, so that the tape is unfolded to a preset length.
[0058] Specifically, the vacuum adhesive suction component is located between the folding mechanism and the shearing station of the cutter, and can reciprocate between the folding mechanism and the shearing station of the cutter to absorb the sheared forming tape, transfer the forming tape from the shearing station to the folding mechanism, and work together with the adhesive applicator located at the folding mechanism to complete the adhesive applicator operation.
[0059] Optionally, such as Figure 3 and Figure 12 As shown, the adhesive preparation mechanism in this embodiment further includes a fourth slide rail and a fourth slider 199. The fourth slide rail is mounted on the frame, with one end facing the cutter and the other end close to the folding mechanism. The fourth slider is slidably mounted on the fourth slide rail. Optionally, the vacuum adhesive suction component 196 in this embodiment includes an adhesive application cylinder 1962 and a vacuum adhesive suction block 1961. The vacuum adhesive suction block is located at the telescopic end of the adhesive application cylinder and is used to absorb the cut adhesive tape. The adhesive application cylinder is mounted on the fourth slider and moves back and forth along the fourth slide rail between the folding mechanism and the cutting position of the cutter. The adhesive application cylinder is used to drive the vacuum adhesive suction block to transfer the adhesive tape at the cutting position of the cutter and to apply the adhesive tape at the folding mechanism. Optionally, the frame in this embodiment is provided with a cable chain, which is located close to the fourth slide rail and is used to arrange and support the cables and air pipes of the vacuum adhesive suction component.
[0060] In this embodiment, the workflow of the hand-operated salute cannon assembly equipment is as follows: First, the outer cylinder feeding mechanism feeds the outer cylinder, which is automatically sorted from the first vibrating plate to the first linear feeder and conveyed along its orientation to the end of the first linear feeder. The outer cylinder separating component pushes out the outer cylinder at the end of the first linear feeder. At the same time, the capping and transfer mechanism moves along the first slide rail to the end of the first linear feeder and rises relative to the first slide plate so that the pneumatic clamp of the capping and transfer mechanism is located above the ejected outer cylinder, so that the capping and transfer mechanism can clamp the outer cylinder. After clamping the outer cylinder, the capping and transfer mechanism moves toward the capping mechanism. At the same time, the capping feeding mechanism feeds the caps, which are automatically sorted from the second vibrating plate to the second linear feeder and conveyed along its direction to the end of the second linear feeder, and then enter the feeding channel of the capping mechanism. Further, the second slide plate drives the transfer positioning clamp and the baffle to move to the discharge end of the feeding channel. The cap enters the arc groove of the baffle, the transfer positioning clamp clamps the cap and transfers it to the corresponding station of the fixed block, aligning the cap with the center of the outer cylinder clamped by the capping transfer mechanism. When the cap is at the corresponding station of the fixed block, the transfer positioning clamp still clamps the cap, while the fixed block pushes the cap to stabilize it. The capping transfer mechanism descends and rotates its outer cylinder around its own axis, so that the outer cylinder is screwed and assembled with the cap. After the outer cylinder and cap are screwed together and assembled, the capping and transfer mechanism releases the outer cylinder and returns along the second slide rail to the discharge end of the outer cylinder feeding mechanism to clamp the outer cylinder. Simultaneously, the adhesive applicator and capping and transfer mechanism move in the same direction to the cap tightening mechanism, clamping the assembled hand-pulled ceremonial cannon with the outer cylinder and cap. While the capping and transfer mechanism moves another outer cylinder from the outer cylinder feeding mechanism to the cap tightening mechanism, the adhesive applicator moves the assembled hand-pulled ceremonial cannon from the cap tightening mechanism to the folding mechanism. After the adhesive applicator clamps the hand-pulled ceremonial cannon to be folded and glued to the folding mechanism, the guide clamp below clamps the pull wire of the hand-pulled ceremonial cannon into the limiting hole to prevent it from shaking. Then, a micro-cylinder drives the folding shaft closer to the pull wire, and a radial drive cylinder drives the folding shaft to lift the pull wire away from the guide clamp. Further, the third slide plate moves upward along the third slide rail, causing the folding shaft to lift the pull wire and bring it close to the outer surface of the outer cylinder. Meanwhile, the adhesive preparation mechanism outputs adhesive tape through the film roll holder. The adhesive tape passes through the guide rollers to the fixing clamp, where it is first fixed. Then, the adhesive clamp is pulled close to the fixing clamp to pick up the free section of the adhesive tape and pull it to a preset length. Then, the cutter cuts the adhesive tape at the end near the fixing clamp to form a single-segment formed adhesive tape. At the same time, the adhesive application cylinder drives the vacuum adhesive suction block to approach the single-segment formed adhesive tape and adsorb it. Further, the adhesive application cylinder and the vacuum adhesive suction block carry the adhesive tape along the fourth slide rail to the folding mechanism.Upon reaching the folding mechanism, the hand-held ceremonial cannon on the adhesive applicator has just completed its folding operation. The adhesive applicator cylinder drives the vacuum suction block to approach the folding line on the outer surface of the hand-held ceremonial cannon on the adhesive applicator. Then, the second servo motor of the adhesive applicator is activated, causing the adhesive applicator to rotate the hand-held ceremonial cannon in one direction by a preset angle, and then return to its initial position and rotate in the opposite direction by a preset angle, thus applying the tape to the hand-held ceremonial cannon and securing the folded pull line on its outer surface. After the tape is applied, the guide clamp releases the pull line, and the adhesive applicator releases the hand-held ceremonial cannon, allowing it to fall into the feeding port below the guide clamp, thus completing the assembly of one hand-held ceremonial cannon.
