Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology in automobile production, and in particular to a cleaning device for the nozzle of an adhesive application robot used in automobile production. Background Technology

[0002] In the automotive manufacturing process, the adhesive application process is a crucial step in ensuring the vehicle body's sealing, structural strength, and reducing noise and vibration. For example, the connection points between car doors and windows and the body frame, as well as the assembly of components in areas such as the engine compartment and chassis, all require precise adhesive application to achieve multiple functions such as waterproofing, dustproofing, sound insulation, and fixation.

[0003] As a core component of adhesive application equipment, the surface cleanliness of the glue gun nozzle directly determines the quality and effectiveness of the adhesive application. If old adhesive, impurities, or moisture remain on the nozzle surface, these contaminants will mix into the new adhesive during subsequent application, leading to poor adhesive flow, uneven application, and quality problems such as incomplete sealing and adhesive peeling. Taking the application of automotive door sealant as an example, if the glue gun nozzle surface is unclean, the sealant may not be able to completely fill the gap between the door and the vehicle frame, causing air and water leaks during driving, seriously affecting the comfort and safety of the vehicle.

[0004] The existing publication number CN219519789U discloses a cleaning device for glue gun nozzles of an adhesive applicator in automobile production, including a cylinder, rotatable turbine blades, and a drive component for driving the turbine blades to rotate. The turbine blades are located inside the cylinder, and the output shaft of the drive component extends from the bottom of the cylinder into the cylinder and connects to the turbine blades. A cover is provided on the top of the cylinder. The cover has an opening for inserting the glue gun nozzle. The rotation of the turbine blades can realize a rolling wave-like rinsing of the glue gun nozzle, which can effectively and quickly remove residual glue on the glue gun nozzle. The cleaning effect is good. Compared with the traditional cleaning of glue gun nozzles with wiping sponges, it can prevent the quality abnormalities caused by unsatisfactory cleaning effect of glue gun nozzles, and can also reduce the need for manual wiping and cleaning during downtime, effectively improving production efficiency and greatly reducing production costs.

[0005] It was found that the above-mentioned device still has shortcomings in use. First, when the device is in use, it uses the rotation of turbine blades to achieve a rolling wave-like rinsing of the glue gun nozzle. Although it can clean the glue gun nozzle, the cleaning point is mainly on the outside of the glue gun nozzle. However, the glue gun nozzle is divided into an inner ring and an outer ring. The water flow impact force generated by the rotation of the turbine blades is difficult to penetrate into the inner ring of the glue gun nozzle. The cleaning effect on the old glue and impurities remaining in the inner ring is negligible. As a result, in actual production, the contaminants in the inner ring of the glue gun nozzle are still present. During subsequent glue application, these residues will be sprayed out with the glue, affecting the uniformity and sealing of the glue application, and thus reducing the overall quality of the automotive glue application process.

[0006] Therefore, it is necessary to provide a new cleaning device for the glue gun nozzle of an adhesive application robot in automobile production to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a glue gun nozzle cleaning device for glue application robots in automobile production.

[0008] The glue gun nozzle cleaning device for automotive production glue application robots provided by this utility model includes: a cylinder and a turbine assembly for cleaning the surface of the glue gun nozzle. The turbine assembly is located inside the cylinder. The surface of the turbine assembly is provided with a plurality of equally spaced arc-shaped blades. A cleaning rod is fixed at the center of the top of the turbine assembly. The surface of the cleaning rod is provided with a plurality of equally spaced nylon bristle rods. The top of the cylinder is provided with an air blowing assembly for drying the surface of the glue gun nozzle.

[0009] Preferably, a mounting cylinder is fixed to the bottom of the cylinder, and one end of the turbine assembly is fixed inside the mounting cylinder;

[0010] The turbine assembly includes a drive motor, a rotating rod, and turbine blades. The drive motor is fixed inside the mounting cylinder. One end of the rotating rod is fixedly connected to the rotor of the drive motor. The other end of the rotating rod passes through the bottom of the cylinder and is fixedly connected to one side of the turbine blade. The turbine blade is located inside the cylinder. The surface of the turbine blade is provided with a plurality of equally spaced arc-shaped blades. A cleaning rod is fixed at the center of the top of the turbine blade.

[0011] Preferably, the top of the cylinder is detachably connected to a mounting box, the top of the mounting box is detachably connected to a cover, the outer circumference of the mounting box is provided with a plurality of equally spaced ventilation holes, the top center of the cover is recessed to form a through hole, the bottom center of the mounting box is recessed to form a through hole, and the size of the through hole is larger than the size of the through hole.

[0012] Preferably, the bottom wall of the mounting box is fixed with a mounting plate, which divides the interior of the mounting box into two independent cavities. The mounting plate is rectangular, and its surface has multiple equidistant ventilation holes.

[0013] Preferably, the inner wall of the mounting plate is provided with a plurality of inclined plates arranged vertically at equal intervals, and the second vent hole is located between two of the inclined plates.

[0014] Preferably, the air blowing assembly includes four air boxes, which are respectively installed on the four outer surfaces of the mounting plate, and a fan is fixed to the inner wall of each air box.

[0015] Compared with related technologies, the glue gun nozzle cleaning device for automotive production glue application robots provided by this utility model has the following beneficial effects:

[0016] 1. This utility model features multiple equidistantly distributed arc-shaped blades on the surface of a turbine assembly. When the turbine assembly rotates within the cylinder, these arc-shaped blades guide the cleaning fluid to form a complex and powerful vortex, cleaning the outer ring of the glue gun nozzle. Simultaneously, the cleaning rod rotates with the turbine assembly, and the nylon bristles brush the inner ring of the glue gun nozzle. For high-viscosity, high-hardness cured adhesives, the nylon bristles provide sufficient friction to scrape them off. For sticky impurities such as oil stains, the nylon bristles can penetrate deep into crevices for cleaning. For hard impurities such as metal particles, the elasticity of the nylon bristles prevents scratches on the glue gun nozzle surface while simultaneously removing them, thus improving the effectiveness of glue gun nozzle cleaning and ensuring a clean and tidy surface, guaranteeing high-quality glue application.

[0017] 2. This utility model has an air blowing component on the top of the cylinder for drying the surface of the glue gun nozzle. After the glue gun nozzle is cleaned, the air blowing component can generate airflow to quickly dry the residual moisture. The air blowing component also allows the gas and liquid to mix fully while the turbine blades drive the cleaning fluid to flow, forming a gas-liquid two-phase flow. This facilitates the generation of a large number of bubbles in the rinsing water flow, making the cleaning of the glue gun nozzle surface more complete and the cleaning effect better.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 ,in, Figure 1 A schematic diagram of the overall structure of the glue gun nozzle cleaning device for an auto manufacturing glue applicator provided by this utility model; Figure 2 A cross-sectional structural diagram of the glue gun nozzle cleaning device for an auto coating robot provided by this utility model. Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 This is a structural diagram of the cleaning component.

[0025] In some embodiments, such as Figures 1 to 4 As shown, it includes a cylinder body 1 and a turbine assembly for cleaning the surface of the glue gun nozzle. The turbine assembly is located inside the cylinder body 1. The turbine assembly is characterized by having a plurality of equally spaced arc-shaped blades 31 on its surface ring, a cleaning rod 32 fixed at the center of the top of the turbine assembly, a plurality of equally spaced nylon bristle rods 33 on the surface ring of the cleaning rod 32, and an air blowing assembly for drying the surface of the glue gun nozzle on the top of the cylinder body 1.

[0026] Specifically, by circumferentially distributed arc-shaped blades 31 on the surface of the turbine assembly, when the turbine assembly rotates within the cylinder 1, the arc-shaped blades 31 can guide the cleaning fluid to form a complex and powerful vortex, cleaning the outer ring of the glue gun nozzle. As the turbine assembly rotates, the cleaning rod 32 also rotates, and the multiple nylon bristle rods 33 circumferentially arranged on the surface of the cleaning rod 32 brush the inner ring of the glue gun nozzle. For high-viscosity, high-hardness cured adhesives, the nylon bristle rods can provide sufficient friction to scrape them off; for sticky impurities such as oil stains, the nylon bristle rods can penetrate deep into crevices for cleaning; for hard impurities such as metal particles, the elasticity of the nylon bristle rods can prevent scratching the glue gun nozzle surface while removing them, improving the effectiveness of glue gun nozzle cleaning, ensuring a clean and tidy glue gun nozzle surface, and providing a guarantee for high-quality glue application.

[0027] Furthermore, in addition to using nylon bristle rods 33, the surface of the cleaning rod 32 of this device can also use flexible fiber cleaning cotton rods, such as cleaning cotton rods formed by weaving and winding polyester fibers, bonded to the surface of the cleaning rod 32 to form a dense fiber layer. The porous structure of the fibers gives it good adsorption capacity, which can effectively adsorb residual glue, impurities and moisture in the glue gun nozzle. For example, when cleaning easily adhering glues such as polyurethane glue, the cleaning cotton rod can quickly absorb the glue, reduce residue, and the soft fibers will not scratch the inner wall of the glue gun nozzle during the cleaning process. It is especially suitable for glue gun nozzles that are sensitive to surface materials or easily damaged, such as glue gun nozzles made of precision ceramics or special plastics.

[0028] Furthermore, by providing an air-blowing component at the top of the cylinder 1 for drying the surface of the glue gun nozzle, after the glue gun nozzle is cleaned, the air-blowing component can generate airflow to quickly dry the residual moisture. The air-blowing component also allows the gas and liquid to mix thoroughly while the turbine blades 31 drive the cleaning fluid to flow, forming a gas-liquid two-phase flow. This facilitates the generation of a large number of bubbles in the rinsing water flow, making the cleaning of the glue gun nozzle surface more complete and the cleaning effect better.

[0029] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 4 As shown, a mounting cylinder 2 is fixed to the bottom of the cylinder block 1, and one end of the turbine assembly is fixed inside the mounting cylinder 2;

[0030] The turbine assembly includes a drive motor 21, a rotating rod 22, and turbine blades 3. The drive motor 21 is fixed inside the mounting cylinder 2. One end of the rotating rod 22 is fixedly connected to the rotor of the drive motor 21. The other end of the rotating rod 22 passes through the bottom of the cylinder 1 and is fixedly connected to one side of the turbine blades 3. The turbine blades 3 are located inside the cylinder 1. The surface of the turbine blades 3 is provided with a plurality of equally spaced arc-shaped blades 31. A cleaning rod 32 is fixed at the center of the top of the turbine blades 3.

[0031] Specifically, during the cleaning of the turbine assembly, the drive motor 21 is first started, which drives the rotating rod 22 to rotate, which in turn drives the turbine blades 3 at the top of the rotating rod 22 to rotate, which in turn drives the cleaning rod 32 to rotate.

[0032] In some embodiments, such as Figure 1 as well as Figure 4 As shown, the top of the cylinder body 1 is detachably connected to the mounting box 4, and the top of the mounting box 4 is detachably connected to the cover 42. The outer ring of the mounting box 41 is provided with a plurality of equally spaced ventilation holes 41. The top center of the cover 42 is recessed inward to form a through hole 421, and the bottom center of the mounting box 4 is recessed inward to form a through hole 422. The size of the through hole 422 is larger than the size of the through hole 421.

[0033] Among them, references are as follows Figure 2 As shown, a slot is provided on the top of the cylinder body 1, and a block is fixed on the bottom of the mounting box 4. The slot and the block are fastened together to install the mounting box 4.

[0034] Among them, references are as follows Figure 2 As shown, the top of the mounting box 4 is also provided with a slot, and the bottom of the cover 42 is fixed with a block. The slot and the block are fastened together to install the cover 42, which makes it easy to replace different covers 42 and thus suitable for cleaning different sizes of glue gun nozzles.

[0035] Specifically, the vent 41 allows external gas to enter the air blowing assembly for supply.

[0036] Furthermore, the size of the second through hole 422 is larger than that of the first through hole 421. The second through hole 422 is located directly below the first through hole 421. The first through hole 421 mainly serves to install the glue gun nozzle and guide the glue gun nozzle. The second through hole 422 facilitates the insertion of the glue gun nozzle into the cylinder 1 for cleaning.

[0037] Furthermore, this invention is installed next to a glue-applying robot used in automobile production and connected to a circuit. The glue-applying robot is taught to reach the designated position of this invention to wait for cleaning. A cover 42 with a suitable through hole 421 is selected according to the glue gun nozzle of the glue-applying robot to be cleaned. Glue softener is added into the cylinder 1 and the cover 42 is closed. The position of the glue-applying robot is taught so that the glue gun nozzle extends into the interior of the cylinder 1 through the through hole 421 on the cover 42. The power is turned on, and the drive motor 21 starts to work. The drive motor 21 drives the turbine blades 3 to rotate at high speed. During the rotation of the turbine blades 3, the liquid in the cylinder 1 can form a vortex state, which can then clean the glue gun nozzle that has extended into the cylinder 1. A suitable fixed cleaning time for the glue gun nozzle is set to achieve the cleaning effect.

[0038] In some embodiments, such as Figures 1 to 4 As shown, the bottom wall of the mounting box 4 is fixed with a mounting plate 43. The mounting plate 43 divides the interior of the mounting box 4 into two independent cavities. The mounting plate 43 is rectangular. The through hole 422 is located at the center of the mounting plate 43. The surface of the mounting plate 43 is provided with a plurality of equally spaced ventilation holes 431.

[0039] The inner wall of the mounting plate 43 is fixed with multiple inclined plates 44 arranged vertically at equal intervals, and the second vent hole 431 is located between two inclined plates 44. The arrangement of multiple inclined plates 44 changes the air flow path. After the airflow is blocked and guided by the inclined plates 44, it will enter the area where the second through hole 422 is located through the second vent hole 431 in a more uniform way, thereby drying the glue gun nozzle. This design improves the uniformity of drying, ensuring that the moisture on the surface of the glue gun nozzle can be dried quickly and thoroughly, and the dried moisture will fall into the cylinder 1 for collection.

[0040] Among them, the second vent hole 431 facilitates the entry of air into the second through hole 422.

[0041] Specifically, the air blowing assembly includes four air boxes 5, which are respectively installed on the four outer surfaces of the mounting plate 43. Each air box 5 has a fan 51 fixed on its inner wall. When the fan 51 is running, it can generate airflow and deliver airflow into the mounting box 4 from all directions, avoiding the concentration of airflow in one direction and ensuring that all parts of the glue gun nozzle are blown by a uniform airflow. The delivered airflow passes through the second vent 431 on the mounting plate 43 to dry the glue gun nozzle. By driving the fan 51 inside the air box 5, the two ends of the air box 5 are hollow, allowing air to enter from the first vent 41 and flow out from the second vent 431 to dry the surface of the glue gun nozzle.

[0042] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
