Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a glue quantity control mechanism for an automatic glue spraying machine for automotive interior parts. Background Technology

[0002] With the rapid development of the automotive industry, the manufacturing precision and appearance quality requirements for interior parts are increasing. Adhesive spraying technology is widely used in the production of automotive interior parts, primarily for bonding different components such as seats, doors, and dashboards. Automatic adhesive spraying machines achieve efficient and uniform adhesive coating by precisely controlling the amount and location of adhesive application. This is of great significance for improving production efficiency, reducing labor costs, and ensuring product quality. The equipment, through an adhesive quantity control mechanism and a mixing and cleaning system, ensures that each adhesive application achieves the desired effect, meeting the automation and precision requirements of modern production lines.

[0003] Many adhesive spraying devices on the market currently have technical limitations, particularly in terms of adhesive uniformity and dispensing accuracy. Many devices use a fixed spraying rate, making it difficult to adjust the adhesive output according to the needs of different interior parts, resulting in uneven spraying. Furthermore, the mixing function of some devices is relatively simple, failing to effectively prevent adhesive deposition and curing on the inner wall of the storage tank, directly affecting the stable supply of adhesive and the spraying effect. In addition, the dispensing head replacement process of existing equipment is cumbersome, failing to meet the need for quick replacement of dispensing heads of different specifications.

[0004] To address this issue, a glue quantity control mechanism for an automatic glue spraying machine for automotive interior parts is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a glue quantity control mechanism for an automatic glue spraying machine for automotive interior parts, aiming to improve the problems of fixed glue spraying rate, uneven glue discharge, and inconvenient glue head replacement in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adhesive quantity control mechanism for an automatic adhesive spraying machine for automotive interior parts, including a worktable, an adhesive storage tank installed on the top of the worktable, a stirring mechanism provided inside the adhesive storage tank, a base fixedly connected to the top of the worktable, a drive assembly provided on the top of the base, two support plates fixedly connected to the top of the worktable, and an adhesive dispensing mechanism provided on the top of the support plates.

[0007] The dispensing mechanism includes a sleeve, which is fixedly connected to the top of the support plate. A piston is slidably connected inside the sleeve, and a push rod is fixedly connected to the outside of the piston. A spring is installed inside the sleeve, and a hose is fixedly connected to the outside of the sleeve. A dispensing head is slidably connected to the end of the hose away from the sleeve. A connecting pipe is fixedly connected to the outside of the sleeve, and the end of the connecting pipe away from the sleeve is fixedly connected to the outside of the glue storage tank.

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

[0009] The stirring mechanism includes a second motor, which is fixedly connected to the top of the glue storage tank. A rotating shaft is fixedly connected to the output end of the second motor, and multiple stirring rods are fixedly connected to the outside of the rotating shaft. A cleaning component is provided at the end of the stirring rod away from the rotating shaft.

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

[0011] The drive assembly includes a motor, which is mounted on the top of the base, and a protruding plate is fixedly connected to the output end of the motor.

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

[0013] The cleaning assembly includes a hollow box, which is fixedly connected to the stirring rod on the side away from the rotating shaft. Multiple springs are installed inside the hollow box, and a limit plate is slidably connected inside the hollow box. A scraper is fixedly connected to the outside of the limit plate.

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

[0015] A one-way valve is fixedly connected inside the hose, a one-way valve is fixedly connected inside the connecting pipe, a rubber ring is fixedly connected to the outside of the hose, and a groove is opened inside the dispensing head, with the rubber ring snapped into the groove.

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

[0017] One end of the second spring is fixedly connected to the piston on the side away from the push rod, and the other end of the second spring abuts against the inner wall of the sleeve. The convex plate abuts against the end of the push rod away from the piston.

[0018] As a further description of the above technical solution:

[0019] A work box is installed on the top of the workbench, and a support frame is fixedly connected to the top of the workbench. The flexible hose is snapped into the top of the support frame.

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

[0021] One end of the spring is fixedly connected to one side of the limiting plate, and the other end of the spring is fixedly connected to the inner wall of the hollow box. The scraper passes through one side of the hollow box and abuts against the inner wall of the glue storage tank.

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

[0023] 1. This utility model employs a two-pronged approach of a convex plate and a spring to precisely control the glue dispensing rate. Compared to traditional devices with a fixed dispensing rate, this design allows the motor's rotation speed to directly adjust the glue dispensing volume, making it more flexible and efficient. Simultaneously, the interference fit between the convex ring and the groove allows for quick replacement of the dispensing head, meeting the needs of different nozzle diameters and avoiding cumbersome disassembly and replacement processes.

[0024] 2. In this invention, the combination of a stirring mechanism and a cleaning component ensures the uniformity and smoothness of the adhesive during discharge. Compared with existing technologies that rely solely on a single stirring device, the synergistic effect of the stirring rod and scraper effectively prevents the adhesive from depositing and sticking on the inner wall of the adhesive storage tank, ensuring the smoothness and consistency of the adhesive each time it is sprayed, and significantly improving the effect and efficiency of the spraying process.

[0033] 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.

[0034] Reference Figure 1 - Figure 6 An embodiment of this utility model provides: an adhesive quantity control mechanism for an automatic adhesive spraying machine for automotive interior parts, including a workbench 5, an adhesive storage tank 1 installed on the top of the workbench 5, a stirring mechanism inside the adhesive storage tank 1, a base 9 fixedly connected to the top of the workbench 5, a drive assembly on the top of the base 9, and two support plates 6 fixedly connected to the top of the workbench 5, with an adhesive dispensing mechanism on the top of the support plates 6.

[0035] The dispensing mechanism includes a sleeve 7, which is fixedly connected to the top of the support plate 6. A piston 23 is slidably connected inside the sleeve 7, and a push rod 12 is fixedly connected to the outside of the piston 23. A spring 24 is installed inside the sleeve 7, and a hose 4 is fixedly connected to the outside of the sleeve 7. A dispensing head 13 is slidably connected to the end of the hose 4 away from the sleeve 7. A connecting pipe 15 is fixedly connected to the outside of the sleeve 7, and the end of the connecting pipe 15 away from the sleeve 7 is fixedly connected to the outside of the glue storage tank 1. A work box 3 is installed on the top of the workbench 5, and a support frame 2 is fixedly connected to the top of the workbench 5. The hose 4 is snapped into the top of the support frame 2. A one-way valve 14 is fixedly connected inside the hose 4, and a one-way valve 16 is fixedly connected inside the connecting pipe 15. A rubber ring 25 is fixedly connected to the outside of the hose 4. A groove 26 is opened inside the dispensing head 13, and the rubber ring 25 is snapped into the groove 26. The workbench 5 provides fixation and support for the overall structure, ensuring stable operation of the equipment. The base 9 supports the motor 10, ensuring its stability during operation. Support plate 6 supports sleeve 7, ensuring its stability during operation. Glue reservoir 1 stores glue, ensuring a continuous glue supply. Sleeve 7 is the glue transfer point, housing various parts. Piston 23 slides inside sleeve 7, drawing glue from reservoir 1 into sleeve 7 and then discharging it. Spring 24 resets piston 23. Hose 4 discharges glue from sleeve 7, serving as a glue delivery channel from sleeve 7 to dispensing head 13. Connecting pipe 15 connects parts reservoir 1 and sleeve 7, ensuring glue can be delivered from reservoir 1 to sleeve 7 under the action of piston 23. Work box 3 is where automotive interior parts are bonded. The glue outlet 13 is used for the final discharge of glue. Its opening size determines the amount of glue discharged. The rubber ring 25 and the groove 26 are interference-fitted, allowing for quick replacement or installation of the glue outlet 13. Different diameter glue outlets 13 can be used to adapt to the bonding of different interior parts. One-way valve 14 ensures that glue can only be discharged from the hose 4, and one-way valve 16 ensures that glue can only be drawn from the glue reservoir 1 into the sleeve 7. The support frame 2 supports the hose 4 and secures it when not in use, preventing contamination of the glue outlet 13.

[0036] Reference Figure 1 - Figure 4 The mixing mechanism includes a second motor 11, which is fixedly connected to the top of the glue storage tank 1. A rotating shaft 18 is fixedly connected to the output end of the second motor 11. Multiple stirring rods 17 are fixedly connected to the outside of the rotating shaft 18. A cleaning component is provided at the end of each stirring rod 17 away from the rotating shaft 18. The second motor 11 is the power source for the mixing mechanism, driving the rotating shaft 18 to rotate, thereby causing the stirring rods 17 to stir the glue in the glue storage tank 1, preventing glue sedimentation and making the glue more uniform. The cleaning component is used to scrape off the glue from the inner wall of the glue storage tank 1, preventing the glue from sticking to the inner wall.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The drive assembly includes a motor 10, which is mounted on the top of the base 9. A protruding plate 8 is fixedly connected to the output end of the motor 10. One end of a spring 24 is fixedly connected to the piston 23 on the side away from the push rod 12, and the other end of the spring 24 abuts against the inner wall of the sleeve 7. The protruding plate 8 abuts against the end of the push rod 12 away from the piston 23. The motor 10 drives the protruding plate 8 to rotate. With the rotation of the protruding plate 8 and in conjunction with the spring 24, the piston 23 slides repeatedly inside the sleeve 7, drawing glue into the sleeve 7 and then discharging it. The rotational speed of the protruding plate 8 determines the glue discharge rate.

[0038] Reference Figure 1 - Figure 4 The cleaning assembly includes a hollow box 22, which is fixedly connected to the stirring rod 17 on the side away from the rotating shaft 18. Multiple springs 19 are installed inside the hollow box 22. A limiting plate 20 is slidably connected inside the hollow box 22, and a scraper 21 is fixedly connected to the outside of the limiting plate 20. One end of each spring 19 is fixedly connected to one side of the limiting plate 20, and the other end is fixedly connected to the inner wall of the hollow box 22. The scraper 21 penetrates one side of the hollow box 22 and abuts against the inner wall of the glue storage tank 1. The hollow box 22 serves to support its internal components, ensuring normal operation. The springs 19 allow the scraper 21 to slide and fine-tune within the hollow box 22 during operation, and also ensure that the scraper 21 always abuts against the inner wall of the glue storage tank 1. The limiting plate 20 prevents the scraper 21 from sliding out of the hollow box 22, ensuring that the scraper 21 can slide smoothly within the hollow box 22.

[0039] Working principle: Before applying adhesive to automotive interior parts, first open the sealed cap on top of the adhesive reservoir 1 and inject an appropriate amount of adhesive. Then, start motor 2 11, which drives the rotating shaft 18 to rotate, thereby driving the stirring rod 17 to fully stir the adhesive in the reservoir 1, ensuring that the adhesive is in a uniform and good working condition. During the stirring process, the scraper 21 slides against the inner wall of the reservoir 1 under the elastic force of spring 19, effectively scraping off the adhesive adhering to the inner wall, preventing adhesive residue and hardening, and ensuring that the adhesive can be smoothly discharged.

[0040] After mixing the adhesive, place the automotive interior parts to be sprayed into the work box 3. Then, remove the hose 4 fixed to the support frame 2 and align the dispensing head 13 with the desired spraying location. Next, start the motor 10. At this time, the convex plate 8 begins to rotate. Under the action of the convex plate 8 and the spring 24, the piston 23 reciprocates within the sleeve 7. The movement of the piston 23 causes the adhesive to be transported from the storage tank 1 through the connecting pipe 15 into the sleeve 7, and then through the hose 4 to the dispensing head 13, completing the spraying process. The rotational speed of the motor 10 directly determines the speed at which the adhesive is discharged from the hose 4, thereby achieving precise adjustment of the adhesive spraying rate.

[0041] When it is necessary to replace the glue dispensing head 13 of different specifications, simply remove the original glue dispensing head 13 from the hose 4, replace it with the new glue dispensing head 13, and ensure that the rubber ring 25 is accurately inserted into the groove 26 to complete the quick replacement operation and meet different glue spraying needs.

[0042] 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.
