Description

Technical Field

[0001] This utility model relates to the field of automatic cleaning technology, and more specifically, to an automatic cleaning device for a glue-spraying robot. Background Technology

[0002] In modern automotive manufacturing, side skirt adhesive application is a crucial process on the car assembly line, and most automakers utilize RPP robots for automated application. However, in practice, after the RPP robot continuously applies adhesive to multiple vehicles, adhesive buildup easily accumulates at the nozzle. This buildup not only affects the quality of the adhesive application but also damages the equipment over time, shortening its lifespan. To address this issue, periodic pauses in application are typically required for manual cleaning of the nozzles by workers. This method is not only time-consuming and labor-intensive, reducing overall production efficiency, but also makes it difficult to ensure optimal cleaning results each time due to variations in manual operation.

[0003] Chinese Patent Publication No. CN215612654U discloses an automatic cleaning device for a glue-spraying robot, including a glue-spraying robot, a glue-spraying nozzle, an air blower, an air pipe, a control system, an air filter, and an air compressor. The glue-spraying nozzle is mounted on the glue-spraying robot. The air blower is connected to the air pipe, and the control system and air filter are both connected between the air pipes. An air compressor is connected to the end of the air pipe. The air blower is aligned with the glue-spraying nozzle, and the compressed air ejected by the air blower is perpendicular to the glue-spraying nozzle, thereby cleaning the glue-spraying nozzle.

[0004] While the aforementioned device can automate and efficiently clean glue-spraying robots, the glue residue at the nozzle is easily scattered and splashed everywhere when the device uses compressed air to clean it, causing environmental pollution in the production area. Furthermore, relying solely on compressed air makes it difficult to remove some dried or highly viscous glue residue, resulting in poor cleaning effectiveness. Currently, no effective solution has been proposed to address these issues. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a shockproof high-voltage distribution cabinet to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An automatic cleaning device for a glue-spraying robot includes a cleaning cylinder with a glue-spraying nozzle inside. The glue-spraying nozzle is mounted on the glue-spraying robot. A rotating cylinder is rotatably installed inside the cleaning cylinder. A drive motor is fixedly installed at one end of the cleaning cylinder. One end of the rotating cylinder rotatably passes through the cleaning cylinder and is connected to the drive shaft of the drive motor. A cleaning brush is fixedly connected inside the rotating cylinder. A discharge pipe is fixedly connected to one side of the bottom of the cleaning cylinder. A solenoid valve is fixedly installed inside the discharge pipe. A water pump is fixedly connected to one side of the surface of the cleaning cylinder. A sealing clamping mechanism is provided on one side of the water pump.

[0008] Furthermore, in order to achieve a sealed cleaning of the glue gun nozzle inside the cleaning cylinder, the sealing clamping mechanism includes a threaded drive rod rotatably mounted on the top of the cleaning cylinder, with adjusting rods threadedly connected to both sides of the surface of the threaded drive rod, and a sealing plate fixedly connected to the end of the adjusting rod. Expansion grooves are opened on both sides of the surface of the cleaning cylinder, and the sealing plate cooperates with the expansion grooves.

[0009] Furthermore, in order to provide power for the transmission of the sealing clamping mechanism, a second transmission motor is fixedly installed on one side of the top of the cleaning cylinder. The end of the transmission shaft of the second transmission motor is fixedly connected to a driving bevel gear, and a driven bevel gear is fixedly installed on the surface of the threaded transmission rod. The driving bevel gear and the driven bevel gear are meshed together.

[0010] Furthermore, in order to ensure the sealing effect of the two sealing plates when clamping the glue gun nozzle, the inner diameter of the sealing plate matches the radius of one side of the glue gun nozzle.

[0011] Furthermore, in order to control the various electrical components on the cleaning cylinder, a microcontroller is fixedly installed on one side of the cleaning cylinder surface.

[0012] Furthermore, to facilitate the replacement of the rotating cylinder inside the cleaning cylinder, a mating groove is provided on the drive shaft of the drive motor, and one end of the rotating cylinder is fixedly installed in the mating groove by bolts.

[0013] Furthermore, in order to achieve a fixed installation of the entire cleaning device, support frames are fixedly connected to both sides of the bottom of the cleaning cylinder, and positioning holes are opened on the surface of the support frames.

[0014] The beneficial effects of this utility model are as follows: the nozzle of the robot's glue spray gun that needs to be cleaned is placed in the cleaning cylinder. After the two sealing plates are clamped to the nozzle by the sealing clamping mechanism, water is injected into the cleaning cylinder. Then, the rotating cylinder is driven by the transmission motor to rotate, so that the cleaning brush strips in the rotating cylinder continuously and automatically clean the nozzle of the glue spray gun. This effectively improves the cleaning efficiency and effect of the glue accumulated on the nozzle of the glue spraying robot, and facilitates the discharge of the glue accumulated after cleaning. It also effectively prevents the glue accumulated from splashing and falling randomly during cleaning, and ensures the cleanliness of the processing environment. Attached Figure Description

[0024] 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.

[0025] According to an embodiment of the present invention, an automatic cleaning device for a glue-spraying robot is provided.

[0026] Example 1:

[0027] like Figures 1-6 As shown, an automatic cleaning device for a glue spraying robot according to an embodiment of the present invention includes a cleaning cylinder 3, with a glue spraying nozzle 2 inside the cleaning cylinder 3. The glue spraying nozzle 2 is mounted on a glue spraying robot 1, which is a six-axis linkage RPP robot used for automated edge glue spraying in automobile production. A rotating cylinder 4 is rotatably mounted inside the cleaning cylinder 3. A drive motor 5 is fixedly mounted on the end of the cleaning cylinder 3 away from the glue spraying nozzle 2. One end of the rotating cylinder 4 rotatably passes through the cleaning cylinder 3 and is connected to the drive shaft of the drive motor 5. A cleaning brush 6 is fixedly connected inside the rotating cylinder 4. A cleaning brush 6 is fixedly connected to one side of the bottom of the cleaning cylinder 3. A discharge pipe 7 is connected, and a solenoid valve 8 is fixedly installed inside the discharge pipe 7 to control the discharge of cleaning water in the cleaning cylinder 3. A water injection pump 9 is fixedly connected to one side of the surface of the cleaning cylinder 3 to inject cleaning water into the cleaning cylinder 3. A sealing clamping mechanism 10 is provided on one side of the water injection pump 9 to seal and clamp the glue spray gun nozzle 2 placed in the cleaning cylinder 3. After the glue spray gun nozzle 2 is sealed and clamped, water is injected into the cleaning cylinder 3, and the rotating cylinder 4 is driven to rotate in the cleaning cylinder 3 by the transmission motor 5. The cleaning brush 6 in the transmission cylinder continuously brushes the glue spray gun nozzle 2 to realize the automated cleaning of the glue accumulated on the glue spray gun nozzle 2.

[0028] like Figures 1-6As shown, the sealing clamping mechanism 10 includes a threaded transmission rod 1001 rotatably mounted on the top of the cleaning cylinder 3. A pair of adjusting rods 1002 are threadedly connected to both sides of the surface of the threaded transmission rod 1001. A semi-circular sealing plate 1003 is fixedly connected to the end of each adjusting rod 1002. A pair of arc-shaped telescopic grooves 1004 are opened on both sides of the surface of the cleaning cylinder 3. The opening size of the telescopic grooves 1004 matches that of the sealing plate 1003, and the semi-circular inner diameter of the sealing plate 1003 is the same as the radius of the glue spray nozzle 2. A second transmission motor 1005 is fixedly mounted on one side of the top of the cleaning cylinder 3. A driving bevel gear 1006 is fixedly connected to the end of the transmission shaft of the second transmission motor 1005. A driven bevel gear 1007 is fixedly mounted on the surface of the threaded transmission rod 1001. The driving bevel gear 1006 meshes with the driven bevel gear 1007, and the second transmission motor 1005 drives the driving bevel gear 1006 and the driven bevel gear 1007. The rotation of the bevel gear 1007 causes the threaded transmission rod 1001 to rotate, which in turn drives the adjusting rods 1002 and the sealing plate 1003 on both sides to move relative to each other. After the glue gun nozzle 2 is placed in the cleaning cylinder 3, the two sealing plates 1003 come close to each other in the telescopic groove 1004 and clamp the glue gun nozzle 2, sealing one end of the cleaning cylinder 3 to prevent the water injected into the cleaning cylinder 3 from flowing out, and stabilizing and limiting the glue gun nozzle 2 during cleaning. A microcontroller 11 is fixedly installed on one side of the surface of the cleaning cylinder 3 for switching control of various electrical components on the cleaning cylinder 3. The drive shaft of the drive motor 5 has a mating groove 12, and one end of the rotating cylinder 4 is fixedly installed in the mating groove 12 by bolts to realize the detachable replacement of the rotating cylinder 4. Support frames 13 are fixedly connected to both sides of the bottom of the cleaning cylinder 3. The surface of the support frame 13 has positioning holes 14 for fixing the cleaning device as a whole at the working position by bolts.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In practical applications, when glue residue accumulates on the glue spraying nozzle 2 of the glue spraying robot 1 after spraying and requires cleaning, the glue spraying robot 1 aligns the nozzle 2 and places it inside the cleaning cylinder 3. The drive motor 1005 drives the active bevel gear 1006 and the driven bevel gear 1007 to rotate, causing the threaded drive rod 1001 to rotate and drive the adjusting rods 1002 and sealing plates 1003 on both sides to move relative to each other. After the nozzle 2 is placed inside the cleaning cylinder 3, the two sealing plates 1003 come closer together within the telescopic groove 1004 and clamp the nozzle 2, thus cleaning the cleaning cylinder. One end of 3 is sealed, and a certain amount of cleaning water is injected into the cleaning bucket by the water pump 9. Then, the drive motor 5 is started. The drive motor 5 drives the rotating drum 4 to rotate continuously in the cleaning bucket, so that the cleaning brush strip 6 on the inner wall of the rotating drum 4 continuously and automatically brushes the glue accumulated on the glue spray gun nozzle 2. After brushing is completed, the discharge pipe 7 is opened by the solenoid valve 8 to discharge the wastewater after cleaning. The microcontroller 11 controls the two sealing plates 1003 to move away and no longer clamp the glue spray gun nozzle 2, so that the glue spraying robot 1 can take out the glue spray gun nozzle 2 after cleaning.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
