Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to an automatic glue spraying machine with adjustable nozzle. Background Technology

[0002] Automatic glue spraying machines are a type of automated equipment widely used in industrial production. They automatically complete the glue spraying operation using mechanical structures and control systems through pre-set programs and parameters. The production process of automotive interior parts has special requirements for glue spraying. Given that automotive interior parts have complex and diverse shapes and strict requirements for bonding effects, ordinary glue spraying machines cannot meet their needs. Therefore, automatic glue spraying machines specifically designed for automotive interior parts have emerged.

[0003] The automotive interior adhesive spraying machine mainly consists of an adhesive storage and delivery system, a nozzle device, an automated control system, and a worktable for carrying the workpiece. During operation, the adhesive storage and delivery system delivers the adhesive to the nozzle at a set pressure and flow rate. The control system controls the adhesive spraying parameters, so that the adhesive is evenly sprayed onto the surface of the automotive interior workpiece placed on the worktable, achieving efficient and precise adhesive spraying operations and meeting the bonding, sealing, and other process requirements of interior parts.

[0004] Existing automotive interior glue spraying machines, thanks to their precise structural design, offer excellent ease of operation and can smoothly complete daily glue spraying tasks. However, because the nozzle adjustment structures of these machines mostly use simple mechanical joint connections and lack precise angle control components, this limitation is amplified when dealing with the glue spraying needs of complex interior parts. The inability to achieve flexible, multi-directional rotation makes it difficult to accurately cover every corner and complex curved surface of the parts, limiting the spraying process to a relatively narrow area. Whether it's uniquely shaped car seat backs or complex dashboard interiors, uniform and comprehensive glue spraying is difficult to achieve, significantly restricting the applicable scenarios and failing to fully meet the diverse and refined process requirements of automotive interior production. Therefore, an automatic glue spraying machine with adjustable nozzles is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic glue spraying machine with an adjustable nozzle, aiming to improve the problems of simple nozzle adjustment structure, limited adjustment angle, inability to accurately cover complex interior parts, and limited applicable scenarios in the existing glue spraying machine for automotive interiors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic glue spraying machine with adjustable nozzles includes a housing with a door on its outer side. A workbench is located inside the housing, and a heat dissipation assembly is located in the middle of the housing. A gantry frame is slidably connected to the top of the workbench. A mounting box is mounted on the side of the gantry frame near the workbench. A micro motor and a micro motor are mounted inside the mounting box. A worm gear is fixedly connected to the output end of the micro motor, and a rotating frame is fixedly connected to the output end of the micro motor. A rotating shaft is rotatably connected to the middle of the rotating frame, and a worm wheel is fixedly connected to the outer side of the rotating shaft. Connecting rods are fixedly connected to both ends of the rotating shaft, and a glue spraying head is fixedly connected to the bottom of the worm wheel. A glue supply assembly is located on the outer side of the housing, and a moving assembly is located on the top of the workbench.

[0008] As a further description of the above technical solution:

[0009] The glue supply assembly includes a glue tank, which is located on the outside of the box. A glue pump is installed in the middle of the glue tank, and a glue tube is fixedly connected to the output end of the glue pump.

[0010] As a further description of the above technical solution:

[0011] The heat dissipation component includes a fan, which is mounted in the middle of the housing. A heat dissipation ring is provided on the side of the housing away from the fan, and heat dissipation holes are evenly distributed in the middle of the heat dissipation ring.

[0012] As a further description of the above technical solution:

[0013] The moving component includes a hydraulic rod disposed in the middle of the housing, and a limit groove is formed on the top of the housing, with the gantry slidably connected to the middle of the limit groove.

[0014] As a further description of the above technical solution:

[0015] The worm and the worm wheel mesh with each other, and the connecting rod and the worm wheel are rotatably connected to the inner side of the rotating frame and the outer side of the rotating frame, respectively.

[0016] As a further description of the above technical solution:

[0017] The mounting box has a groove on the side near the spray nozzle, the connecting rod is slidably connected to the middle of the groove, and a storage box is provided on the top of the workbench.

[0020] As a further description of the above technical solution:

[0021] Heat sinks are evenly distributed on the side of the heat dissipation hole closest to the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a micro motor drives the worm gear to rotate, and the meshing of the worm gear and worm wheel drives the worm wheel, rotating shaft, connecting rod and spray head to rotate, realizing the angle adjustment of the spray head in the X-axis direction. A micro motor drives the rotating frame to rotate, thereby driving the spray head to rotate in the Y-axis direction. The multi-dimensional adjustment method allows the spray head to be flexibly adjusted to different angles, increasing the spraying area, expanding the application scenarios of the spray machine, and meeting the diversified and refined process requirements in automotive interior production.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic glue spraying machine with adjustable nozzles, comprising a housing 1, a door 2 mounted on the outer side of the housing 1, a workbench 3 disposed inside the housing 1, a heat dissipation assembly 16 disposed in the middle of the housing 1, a gantry frame 4 slidably connected to the top of the workbench 3, a mounting box 7 mounted on the side of the gantry frame 4 near the workbench 3, a micro motor 8 and a micro motor 13 disposed inside the mounting box 7, a worm gear 9 fixedly connected to the output end of the micro motor 8, a rotating frame 14 fixedly connected to the output end of the micro motor 13, and a rotating shaft rotatably connected to the middle of the rotating frame 14. 11. A worm gear 12 is fixedly connected to the outer side of the rotating shaft 11. Connecting rods 10 are fixedly connected to both ends of the rotating shaft 11. A glue spray head 5 is fixedly connected to the bottom of the worm gear 12. A glue supply assembly 21 is provided on the outer side of the housing 1. A moving assembly 25 is provided on the top of the workbench 3. The glue supply assembly 21 includes a glue tank 22. The glue tank 22 is located on the outer side of the housing 1. A glue pump 23 is installed in the middle of the glue tank 22. A glue tube 24 is fixedly connected to the output end of the glue pump 23. The worm 9 and the worm gear 12 mesh with each other. The connecting rod 10 and the worm gear 12 are rotatably connected to the inner side and the outer side of the rotating frame 14, respectively.

[0034] Specifically, by starting the micro motor 8, the worm gear 9 rotates. Through the meshing of the worm gear 9 and the worm wheel 12, the worm wheel 12 rotates, which in turn drives the connected rotating shaft 11 and connecting rod 10. This allows for precise angle adjustment of the spray head 5 in the X-axis direction, enabling the spray head 5 to flexibly adjust its X-axis angle according to the shape of the automotive interior parts, evenly covering the area of ​​the parts in that direction. Simultaneously, the micro motor 13 starts and drives the rotating frame 14 to rotate, causing the connected rotating shaft 11, connecting rod 10, worm wheel 12, and... The glue spray head 5 is linked to the Y-axis, which enables the glue spray head 5 to adjust its angle. This enhances the adaptability of the glue spray head 5 to complex curved surfaces and irregular structures, allowing it to spray glue from different Y-axis angles. The coordinated operation of multiple structures allows the glue spray head 5 to flexibly and accurately adjust its angle in the X and Y axes, which helps to improve the quality and efficiency of glue spraying. The glue pump 23 draws glue from the glue tank 22 and delivers the glue to the glue spray head 5 through the glue tube 24, continuously providing the glue spray head 5 with sufficient glue, enabling the glue spray head 5 to perform stable glue spraying operations at different angles.

[0035] Reference Figure 2 and Figure 5 The heat dissipation component 16 includes a fan 17, which is mounted in the middle of the housing 1. A heat dissipation ring 18 is provided on the side of the housing 1 away from the fan 17. Heat dissipation holes 19 are evenly distributed in the middle of the heat dissipation ring 18. The moving component 25 includes a hydraulic rod 26, which is located in the middle of the housing 1. A limit groove 27 is provided on the top of the housing 1. The gantry 4 is slidably connected to the middle of the limit groove 27. Heat dissipation fins 20 are evenly distributed on the side of the heat dissipation holes 19 near the housing 1.

[0036] Specifically, the fan 17 draws in cool outside air into the housing 1. The air flows through the heat dissipation ring 18, and with the help of the heat dissipation holes 19 and heat dissipation fins 20 evenly distributed in the middle of the heat dissipation ring 18, the heat generated by the glue spraying machine and other devices is quickly dissipated, enabling the glue spraying machine to operate stably for a long time and ensuring the continuity of automotive interior production. The hydraulic rod 26 extends and retracts, causing the gantry 4 to slide within the limit groove 27, allowing the lateral position of the nozzle above the worktable 3 to be flexibly adjusted. This enables precise glue spraying according to different positions of automotive interior workpieces, avoids blind spots in glue spraying, and further improves the flexibility and comprehensiveness of the glue spraying machine operation.

[0037] Reference Figure 3 The mounting box 7 has a groove 15 on the side near the spray nozzle 5, and the connecting rod 10 is slidably connected in the middle of the groove 15. The top of the workbench 3 is provided with a storage box 6, and the spray nozzle 5 is fixedly connected to the end of the glue tube 24 away from the glue pump 23.

[0038] Specifically, by opening a groove 15 on the side of the mounting box 7 near the spray head 5 and sliding the connecting rod 10 in the middle, the connecting rod 10 can slide smoothly in the groove 15 when the angle of the spray head 5 is adjusted, providing stable support for the multi-angle adjustment of the spray head 5 and ensuring smooth and accurate rotation in the X and Y axes. By fixing the spray head 5 to the end of the glue tube 24 away from the glue pump 23, it is ensured that the glue pump 23 can stably deliver the glue drawn from the glue tank 22 to the spray head 5 through the glue tube 24, realizing continuous and stable glue spraying and ensuring glue spraying quality and production continuity.

[0039] Working principle: First, the hydraulic rod 26 extends and retracts, causing the gantry 4 to slide within the limiting groove 27, thereby adjusting the lateral position of the nozzle above the worktable 3. Then, the micro motor 1 8 and micro motor 2 13 inside the mounting box 7 are turned on. Micro motor 1 8 rotates and drives the worm gear 9 to rotate. Since the worm gear 9 and the worm wheel 12 mesh with each other, the worm wheel 12 is driven to rotate. The worm wheel 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the connecting rod 10 to rotate, thereby driving the angle adjustment of the spray head 5 in the X-axis direction. Micro motor 2 13 drives the rotating frame 14 to rotate. The rotating shaft 11, connecting rod 10, worm wheel 12, and spray head 5 connected to the rotating frame 14 rotate accordingly, realizing the angle adjustment of the spray head 5 in the Y-axis direction, so that the spray head 5 can be flexibly adjusted to different angles.

[0040] Secondly, during the glue spraying process, the glue supply component 21 starts to work, the glue pump 23 draws out the glue from the glue tank 22 and delivers it to the glue spray head 5 through the glue tube 24. The glue spray head 5 sprays the glue evenly onto the automotive interior parts placed in the storage box 6 on the workbench 3 according to the preset parameters. At the same time, the heat dissipation component 16 operates and the fan 17 rotates, drawing cold air from the outside into the housing 1. The air flows through the heat dissipation ring 18 and carries away the heat generated by the glue spraying machine through the heat dissipation holes 19 and heat dissipation fins 20 evenly opened in the middle of the heat dissipation ring 18.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
