Description

Technical Field

[0001] This invention belongs to the field of shell coating technology, and specifically relates to a speaker shell coating and sealing device. Background Technology

[0002] A speaker enclosure adhesive sealing device is a specialized device or system used to uniformly and precisely apply adhesive to the joints of a speaker enclosure to achieve a sealed connection between the various components of the enclosure. By applying adhesive to the speaker enclosure, a continuous sealing layer is formed, preventing external media such as air, moisture, and dust from entering the speaker enclosure and avoiding affecting speaker performance or causing damage to internal components. The adhesive not only plays a sealing role, but also enhances the connection strength between the various components of the enclosure, improves the overall structural stability of the speaker enclosure, and reduces loosening or cracking caused by vibration or external impact.

[0003] Traditional clamps typically hold the outer wall of the housing, which can cause some areas of the outer wall to be blocked by the clamp. The blocked areas cannot receive adhesive, resulting in missing adhesive in these areas. Meanwhile, the unblocked areas may have too much or too little adhesive, resulting in uneven adhesive application. This affects the overall coverage of the adhesive application and makes it difficult to ensure that every part of the outer wall of the housing is evenly coated with adhesive.

[0004] Therefore, the present invention provides a speaker shell adhesive sealing device. Summary of the Invention

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 9 As shown, the present invention provides a technical solution: a speaker shell gluing and sealing device, including a workbench 1, a loading platform 2 above the workbench 1, a speaker shell resting on the loading platform 2, an inner support assembly on one side of the loading platform 2, the inner support assembly including two sets of inner support plates 7, each set of inner support plates 7 having multiple plates and being able to move outwards simultaneously, a paint tank 3 above each set of inner support plates 7, a liquid pipe 5 fixedly connected to one side of each paint tank 3, a liquid pump 4 being installed outside each liquid pipe 5, a nozzle 6 being fixedly connected to one end of each liquid pipe 5, a drive assembly on one side of each of the two sets of inner support plates 7, the drive assembly driving the two sets of inner support plates 7 to rotate periodically and change positions, and the drive assembly is equipped with a loading assembly and a rotation assembly, the loading assembly causing the speaker shell to be loaded onto the loading platform 2 when the two sets of inner support plates 7 change positions, and the rotation assembly driving one set of inner support plates 7 to rotate.

[0024] During operation: First, multiple speaker shells from the same batch are placed in a designated temporary storage location. After the drive assembly is activated, the two sets of inner support plates 7 begin to rotate periodically (i.e., revolve). During rotation, one set of inner support plates 7 triggers the feeding assembly, pushing a shell directly above the feeding platform 2. After both sets of inner support plates 7 have completed their rotation, one set of inner support plates 7 is precisely positioned to the side of the feeding platform 2, and the arrangement of multiple inner support plates 7 matches the inner cavity of the shell. At this time, the inner support assembly is activated, driving multiple inner support plates 7 to move outward synchronously, so that their outer walls fit tightly against the inner walls of the shell, forming a stable internal clamping state. Subsequently, driven by the drive assembly, the clamped shell rotates periodically (i.e., revolves) together with the inner support plates 7. Meanwhile, the paint tank 3 and the nozzle 6 are always aligned with the outer wall of the shell, and the adhesive is sprayed from the nozzle 6 onto the outer wall of the shell through the liquid pump 4 and the liquid pipe 5. During the revolution, the rotation component plays a role, driving the clamped shell to rotate on its own axis while revolving around the center. Through the combined motion of revolution and rotation, it is ensured that every part of the outer wall of the shell can rotate to the area below the nozzle 6, thereby completing a comprehensive and uniform adhesive coating process. After the adhesive coating is completed, the drive component is restarted to disconnect the processed shell from the inner support component, allowing the coated shell to leave this area for unloading. At the same time, the inner support component is triggered to load the material onto the loading platform 2, realizing a continuous and automated adhesive coating and sealing operation. Through the above embodiments, the two sets of inner support plates 7 are driven to periodically rotate 180 degrees to achieve workstation switching. The rotation enables alternating operation of two workstations, improving equipment utilization. When one workstation is applying glue, the other workstation is simultaneously feeding material. Multiple inner support plates 7 move outward synchronously to clamp the shell from the inside, avoiding the clamping of the outer wall of the shell by traditional clamps, which affects the comprehensiveness of glue application, and is suitable for shells with different inner cavity diameters. During the rotation, the self-rotating component drives the shell to rotate, so that every part of the outer wall of the shell can rotate to below the nozzle 6, solving the problem of insufficient glue application on the bottom or sides of the shell during the rotation, and ensuring the consistency of the glue layer thickness.

[0025] like Figures 4 to 7 As shown, the drive assembly includes a fixed platform 18, which is fixedly installed on the top of the workbench 1. A servo motor 16 is fixedly connected above the fixed platform 18. The output shaft of the servo motor 16 is fixedly connected to a central shaft 17. Connecting plates 8 are fixedly connected to both sides of the central shaft 17. Two sets of inner support plates 7 are located on one side of the connecting plates 8 respectively. A support frame 10 is fixedly connected to one end of each of the two connecting plates 8. Paint tanks 3 are fixedly installed above the support frames 10 respectively.

[0026] During operation: The servo motor 16 drives the central shaft 17 to rotate periodically 360 degrees, causing one set of inner support plates 7 to rotate to one side of the loading platform 2 and trigger loading. The other set of inner support plates 7 rotates to the glue application station. At this time, the paint tank 3 rotates with the support frame 10 to the upper part of the corresponding glue application station, ensuring that the paint supply position matches the glue application requirements. After completing a 180-degree rotation, the inner support plate 7 where the glued shell is located moves out of the glue application station. The unloaded inner support plate 7 rotates to the side of the loading platform 2, and the paint tank 3 switches positions synchronously. The drive components achieve station alternation and paint supply coordination through periodic rotation, ensuring continuous glue application and sealing operations.

[0027] like Figures 5 to 7 As shown, the inner support assembly specifically includes two telescopic rods 9, which are rotatably connected to the inner walls of the centers of the two connecting plates 8. One end of each telescopic rod 9 is slidably connected to a connecting rod 11, and the outer wall of the connecting rod 11 is fixedly connected to a spring-loaded sleeve 12. The surface of the spring-loaded sleeve 12 is provided with multiple inclined grooves, which match the number of inner support plates 7. The inner walls of the inclined grooves are slidably connected to inner sliders 13, and the top of the inner sliders 13 is fixedly connected to the bottom surface of the inner support plate 7.

[0028] During operation: When the servo motor 16 drives the connecting plate 8 to rotate to the side of the loading platform 2, the unloading component is triggered, causing the outer shell to stop above the loading platform 2. At this time, multiple inner support plates 7 are aligned with the inner cavity of the outer shell. The telescopic rod 9 is then extended, and through the connecting rod 11, it drives the spring-loaded sleeve 12 and multiple inner support plates 7 to gradually penetrate into the inner cavity of the outer shell. After entering the inner cavity of the outer shell, the outer walls of the multiple inner support plates 7 are temporarily not in contact with the inner wall of the outer shell. As the connecting rod 11 continues to move, the spring-loaded sleeve 12 is compressed, causing it to slide on the outer wall of the connecting rod 11. Meanwhile, due to the inner support plates 7... The inner slider 13 is slidably connected to the inclined groove on the spring sleeve 12. As the spring sleeve 12 slides, the inner slider 13 slides in the inclined groove, thereby driving multiple inner support plates 7 to move outward synchronously until the outer wall of the inner support plate 7 is tightly attached to the inner wall of the outer shell, forming a stable inner clamping state. When the glue application is completed and the material needs to be unloaded, the telescopic rod 9 retracts, driving the connecting rod 11 to move in the opposite direction. The spring sleeve 12 loses its squeezing force, and the inner support plate 7 gradually retracts inward under the cooperation of the spring sleeve 12, the inclined groove, and the inner slider 13, detaching from the attachment to the inner wall of the outer shell, thereby releasing the clamping and facilitating the unloading of the outer shell.

[0029] like Figures 8 to 9 As shown, a support plate 31 is fixedly connected to the top of the workbench 1, and an arc plate 14 is fixedly connected above the support plate 31. An arc groove 15 is provided on the inner wall of the arc plate 14. The size of the inner wall of the arc groove 15 matches the diameter of the connecting rod 11. The arc plate 14 is attached to one side of the outer shell of the loading platform 2.

[0030] During operation: After multiple inner support plates 7 enter the inner cavity of the outer shell under the control of the telescopic rod 9, the connecting rod 11 continues to move and inserts into the inner wall of the arc-shaped slide groove 15; at this time, the spring-loaded sleeve 12 touches the side of the arc-shaped plate 14, and is squeezed by its side wall because it cannot pass through, and then moves on the outer wall of the connecting rod 11; the movement of the spring-loaded sleeve 12 causes multiple inner sliders 13 to slide along its inclined slide groove, driving multiple inner support plates 7 to expand outward at the same time until they are tightly attached to the inner wall of the outer shell, achieving the inner clamping effect; during the entire 180-degree revolution of glue application, the connecting rod 11 always slides along the inner wall of the arc-shaped slide groove 15, and the spring-loaded sleeve 12 is continuously squeezed by the side of the arc-shaped slide groove 15, ensuring that the inner support plates 7 are firmly clamped to the inner wall of the outer shell.

[0031] like Figure 4 and Figure 7 As shown, the self-rotating component includes a gear 23, which is fixedly connected to the outer wall of the telescopic rod 9. An arc-shaped external toothed ring 19 is fixedly connected above the fixed platform 18. A rack assembly 20 is fixedly connected to one side of the arc-shaped external toothed ring 19. The teeth of the gear 23 can mesh with the teeth of the rack assembly 20, and the number of teeth of the rack assembly 20 is the same as the number of teeth of the gear 23.

[0032] During operation: After the inner clamping of the outer shell is completed, the drive assembly drives the outer shell to rotate 180 degrees. During the initial 90-degree rotation, as the outer shell moves, the gear 23 fixed on the outer wall of the telescopic rod 9 gradually approaches the rack assembly 20 on one side of the arc-shaped outer gear ring 19 until the teeth of the gear 23 mesh with the teeth of the rack assembly 20. Since the rack assembly 20 is fixed, when the gear 23 meshes with the rack assembly 20 as the outer shell rotates, the gear 23 rotates on its own axis. Through the fixed connection with the telescopic rod 9, the rotational motion is transmitted to multiple inner support plates 7, thereby driving the outer shell clamped by the inner support plates 7 to rotate synchronously. At the same time, the liquid pump 4 starts, extracts the paint from the paint tank 3, and sprays it evenly onto the rotating outer shell surface through the spray nozzle 6, achieving all-round coating of the outer shell.

[0033] like Figure 4 and Figure 7 As shown, a rack assembly 21 is fixedly connected to the other side of the arc-shaped external gear ring 19. The teeth of the rack assembly 21 can also mesh with the teeth of the gear 1 23. The number of teeth of the rack assembly 21 is the same as the number of teeth of the gear 1 23. A cooling component is provided above the rack assembly 21.

[0034] During operation: The drive assembly drives the housing to rotate 180 degrees. During the subsequent 90-degree rotation, as the housing continues to move, the gear 23, which was initially disengaged, gradually approaches the rack assembly 21 on the other side of the arc-shaped external gear ring 19, until the teeth of gear 23 and rack assembly 21 mesh again. Since the adhesive application has been completed at this point, when gear 23 and rack assembly 21 mesh and rotate, it will drive the inner support plate 7 and the clamped housing to continue rotating. Simultaneously, the cooling assembly above rack assembly 21 is activated to cool the paint sprayed on the housing surface, accelerate paint curing, and improve the adhesive sealing quality. During the remaining 90-degree rotation, gear 23 continues to mesh with rack assembly 21, ensuring that the housing completes the cooling process while rotating, until the entire 180-degree rotation cycle ends, at which point the housing has cooled and cured and the adhesive is evenly applied.

[0035] like Figures 8 to 9 As shown, the cooling assembly includes a condenser plate 22, which is arc-shaped and fixedly connected above the arc-shaped slide groove 15. The width of the condenser plate 22 is greater than the width of the outer shell.

[0036] During operation: The outer shell, which has already undergone the adhesive application, continues to rotate under the drive of gear 23. At the same time, the arc-shaped condenser plate 22, located above rack assembly 21 and wider than the outer shell, begins to function. Low-temperature cooling medium circulates inside the condenser plate 22, and its surface temperature is much lower than the ambient temperature. When the outer shell rotates and passes under the condenser plate 22, the condenser plate 22 fully covers the surface of the outer shell, providing efficient cooling for the paint sprayed on the surface of the outer shell, accelerating the paint curing process, and improving the adhesive sealing quality.

[0037] like Figures 2 to 3 As shown, the feeding assembly includes an inclined preparation platform 24. One end of the inclined preparation platform 24 is fixedly connected to a hinge seat 25. The shaft of the hinge seat 25 is fixedly connected to one end of the feeding platform 2. The shaft of the hinge seat 25 is fixedly connected to a gear 26. One side of each of the two connecting plates 8 is fixedly connected to an arc-shaped internal gear ring 27. The inner side of the arc-shaped internal gear ring 27 is fixedly connected to a rack assembly 28. The teeth of the gear 26 can mesh with the teeth of the rack assembly 28.

[0038] During operation: In the initial state, before the inner support plate 7 rotates to the designated position for material handling, all the outer shells are neatly arranged above the inclined preparation platform 24, and are tightly pressed together, forming a stable stacked state using their own gravity and tilt angle; at this time, the loading platform 2 and the inclined preparation platform 24 maintain a V-shape, and the first outer shell to be unloaded is precisely stuck in the slot between the inclined preparation platform 24 and the loading platform 2, with its bottom surface in contact with the surface of the loading platform 2, and its side blocked by the edge of the inclined preparation platform 24, in a ready-to-unload position; as the drive component rotates, it drives the connecting plate 8 and the arc-shaped internal gear ring 27 to rotate synchronously. When the rack assembly 28 on the inner side of the arc-shaped internal gear ring 27 moves to the meshing position with the gear 26, the gear 26 rotates under the drive of the rack assembly 28, which in turn drives the shaft of the hinge seat 25 to rotate, causing the loading platform 2, which was originally in a V-shaped state, to rotate relative to the inclined preparation platform 24. During this process, the first shell that was originally stuck at the slot loses the obstruction of the edge of the inclined preparation platform 24 and is pushed by the rotation of the loading platform 2, and begins to slide smoothly along the inclined surface between the inclined preparation platform 24 and the loading platform 2, and finally slides accurately to the designated position on the surface of the loading platform 2, completing the loading action of a single shell.

[0039] like Figures 2 to 3 As shown, the inclined preparation table 24 has an opening groove 32 on its surface. The bottom of the loading table 2 is fixedly connected to a limiting plate 29. One end of the limiting plate 29 is pointed and located in the inner wall of the opening groove 32. The surface of the inclined preparation table 24 is symmetrically fixedly connected to a protective plate 33. The bottom of the loading table 2 is symmetrically fixedly connected to a torsion spring 30. The end of the torsion spring 30 away from the loading table 2 is fixedly connected to the bottom of the inclined preparation table 24.

[0040] During operation: The protective plate 33 ensures that the outer shells are always stably arranged on the inclined material preparation platform 24, providing reliable material support for subsequent loading operations. As the drive assembly operates, it drives the connecting plate 8 and the arc-shaped internal gear ring 27 to rotate synchronously. When the rack assembly 28 on the inner side of the arc-shaped internal gear ring 27 moves to the meshing position with the gear 26, the gear 26 rotates under the drive of the rack assembly 28, which in turn drives the shaft of the hinge seat 25 to rotate, causing the loading platform 2, which was originally in a V-shape, to rotate relative to the inclined material preparation platform 24. The loading platform 2 gradually lifts upward. During this process, the tip of the limiting plate 29 extends into the upper surface of the inclined material preparation platform 24 to limit the remaining outer shells and prevent them from sliding downward. The lifting force of the loading platform 2 causes the outer shell to slide smoothly along the inclined surface between the inclined preparation platform 24 and the loading platform 2, eventually landing accurately at the designated position on the surface of the loading platform 2, completing the loading action of a single outer shell. After loading is completed, as the arc-shaped internal gear ring 27 continues to rotate, the gear 26 and the rack 28 disengage. At this time, under the elastic restoring force of the torsion spring 30, the loading platform 2 begins to rotate in the reverse direction to reset. At the same time, the tip of the limiting plate 29 returns to the inner wall of the opening slot 32 until the loading platform 2 and the inclined preparation platform 24 return to the initial V-shaped state, waiting for the next loading command. Meanwhile, the subsequent outer shells automatically move forward under the action of gravity to fill the position of the removed outer shells, preparing for the next loading.

[0041] like Figure 1 As shown, a feeding platform 34 is fixedly connected to the bottom of the workbench 1.

[0042] During operation: After the outer shell completes a 180-degree revolution, it will stop on the inclined surface of the unloading platform 34. At this time, the drive component will start again and disconnect the processed outer shell from the inner support component. Since the unloading platform 34 is designed with an inclined surface, the outer shell will automatically slide down the inclined surface of the unloading platform 34 under its own gravity, thereby realizing automatic unloading operation.
