Description

Technical Field

[0001] This utility model relates to the technical field of carpet production and processing equipment, specifically to a carpet spraying device based on visual recognition. Background Technology

[0002] In the carpet manufacturing process, after the pile is placed on the backing fabric, glue needs to be sprayed on the back of the backing fabric to fix the pile. Currently, when producing some customized carpets with different specifications and sizes, manual spraying is usually used, which has high flexibility. However, the speed of manual spraying depends on the operator's skill level and physical strength, resulting in low production efficiency and poor spraying quality stability. Therefore, this utility model proposes a carpet spraying device with high flexibility based on visual recognition that can adapt to different specifications. Utility Model Content

[0003] This invention provides a carpet spraying device based on visual recognition, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A carpet spraying device based on vision recognition includes a spraying assembly with a feed pump and a spray gun;

[0006] An electrically controlled moving assembly, wherein the electrically controlled moving assembly is provided with a spraying bracket that is moved by a motor drive;

[0007] The spray gun is detachably mounted on the spraying bracket. The spray gun sprays downwards at an adjustable angle. A scraper is also provided on one side of the spray gun at an adjustable angle. One end of the scraper is rotatably connected to the spraying bracket. A linear driver is also provided on the spraying bracket to drive the scraper to rotate.

[0008] The spraying bracket is also equipped with a visual recognition component for identifying the outline of the carpet.

[0009] A control component, which is electrically connected to the electronically controlled moving component, the spraying component, the linear actuator, and the vision recognition component.

[0010] As a further improvement, the linear actuator is an electric push rod, which is mounted on a rotating base. The rotating base is rotatably engaged with the spraying bracket, and the extended end of the linear actuator is hinged to the scraper.

[0011] As a further improvement, the spraying bracket includes a main bracket and a secondary bracket. The bottom of the secondary bracket is hinged to the main bracket, and the main bracket is also provided with an angle adjustment plate for adjusting the angle of the secondary bracket. The spray gun is detachably fixed to the secondary bracket by a fixing buckle.

[0012] As a further improvement, the electrically controlled moving assembly also includes tracks on both sides, each track having a drive base. The drive base contains a first motor and a drive wheel for moving on the track. An optical shaft and a rack are mounted between the two drive bases. The spraying bracket slides with the optical shaft. The spraying bracket also has a second motor, and a gear on the shaft of the second motor engages with the rack.

[0013] As a further improvement, the scraper has a rounded corner on the side away from the side rotatably connected to the spraying bracket.

[0014] As a further improvement, the nozzle on the spray gun is a fan-shaped nozzle.

[0015] As a further improvement, the visual recognition component includes a camera and a fill light, both mounted on the main bracket.

[0016] The beneficial effects of this utility model are:

[0017] The automated movement of the spray gun and the use of a vision recognition component enable uniform spraying. The linear actuator controls the scraper's rotation in real time, performing a smoothing operation during the spraying process. The entire process requires no manual intervention, improving overall workflow and efficiency. Under the control of the control component, the feed pump delivers adhesive to the spray gun according to the set flow rate and pressure, ensuring uniform adhesive application and avoiding uneven application caused by inconsistent force and speed during manual spraying. This results in a more even distribution of adhesive on the back of the carpet backing, effectively fixing the pile. The vision recognition component scans the carpet outline and plans the path, ensuring that the spray gun accurately covers every area of ​​the carpet that needs spraying, preventing any missed areas. Furthermore, data can be collected again after spraying to check the adhesive coverage, further ensuring quality stability and making the product more reliable. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Reference Figure 1-2 As shown, a carpet spraying device based on vision recognition includes a spraying assembly with a material pump 7 and a spray gun 3. The material pump 7 is located on a platform and connected to the spray gun 3 via a hose. An electrically controlled moving assembly 1 is provided with a spraying bracket 2 that is moved by a motor. When the electrically controlled moving assembly 1 is in operation, it can identify the spatial position of the spraying bracket 2.

[0026] The spray gun 3 is detachably mounted on the spraying bracket 2. The spray gun 3 sprays downwards and the tilt angle is adjustable. A scraper 5 is also provided on one side of the spray gun 3 in the tilt direction. One end of the scraper 5 is rotatably connected to the spraying bracket 2. A linear driver 4 is also provided on the spraying bracket 2 to drive the scraper 5 to rotate.

[0027] The spraying bracket 2 is also equipped with a visual recognition component 6 for recognizing the outline of the carpet;

[0028] The control component 8 contains necessary electronic components and software. The software program can be modified as needed. The control component 8 is electrically connected to the electronically controlled moving component 1, the spraying component, the linear driver 4, and the vision recognition component 6. The control component 8 can be set on a platform or on the spraying bracket 2.

[0029] When spraying begins, the carpet to be processed is first fixed on the work platform. The control component 8 controls the electronically controlled moving component 1 to move the vision recognition component 6 and scan the carpet outline, which is then transmitted to the control component 8. The control component 8 first plans the path, then moves the spray gun 3 to the initial position of the path, controls the start of the spraying component, and the material pump 7 starts working, delivering the glue to the spray gun 3 according to the set flow rate and pressure. At the same time, it sends a command to the motor in the electronically controlled moving component 1 to drive the motor to move the spraying bracket 2. Under the command of the control component 8, the linear drive 4 drives the scraper in a timely manner. 5. Flipping: For example, during the spraying process, the spray gun 3 sprays glue onto the carpet surface. The freshly sprayed glue needs to be smoothed to ensure better contact and penetration with the carpet fibers, thereby enhancing the adhesion and preventing paint buildup. The scraper 5 flips downwards to contact the carpet surface. The flipping angle can be set according to different carpet materials and thicknesses for better results. At certain stages, when smoothing is not needed or during backward movement (moving towards the scraper 5), the scraper 5 flips upwards away from the carpet surface, completing the planned path. Furthermore, the electronically controlled moving component 1 can be driven again to move the visual recognition component 6, collecting data from the carpet surface and sending it to the control device. Software algorithms then check for even glue coverage, missing areas, and abnormal buildup.

[0030] Specifically, the linear actuator 4 preferably adopts an electric push rod, which has lower maintenance requirements and is more conducive to precise control. The linear actuator 4 is mounted on a rotating base, which is rotatably engaged with the spraying bracket 2. The extended end of the linear actuator 4 is hinged to the scraper 5.

[0031] Specifically, to facilitate the adjustment of the tilt angle of the spray gun 3, the spraying bracket 2 includes a main bracket 21 and a secondary bracket 22. The bottom of the secondary bracket 22 is hinged to the main bracket 21, and the main bracket 21 is also provided with an angle adjustment plate 23 for adjusting the angle of the secondary bracket 22. The spray gun 3 is detachably fixed to the secondary bracket 22 by a fixing buckle.

[0032] More specifically, the visual recognition component 6 includes a camera and a fill light, both mounted on the main bracket 21. The fill light provides the necessary illumination to ensure image quality.

[0033] Specifically, the electrically controlled moving component 1 also includes tracks 11 on both sides, with the carpet laid between the two tracks 11. Each track 11 is equipped with a drive base 12, and the drive base 12 contains a first motor 15 for moving on the track 11 and a drive wheel. A light shaft 13 and a rack 14 are mounted between the two drive bases 12. The spraying bracket 2 is slidably engaged with the light shaft 13. The spraying bracket 2 is also equipped with a second motor 16, and a gear on the shaft of the second motor 16 engages with the rack 14, thereby realizing the horizontal and vertical movement of the paint bracket on the plane. The paint bracket is at a certain distance from the carpet surface. The position of the spraying bracket 2 is calculated by the number of rotations of the first motor 15 and the second motor 16 through a software algorithm.

[0034] Specifically, the scraper 5 has rounded corners on the side away from the rotating connection with the spray bracket 2 to prevent sharp edges from scratching the carpet when in contact with it.

[0035] Specifically, the nozzle on the spray gun 3 is a fan-shaped nozzle. The fan-shaped nozzle can cover a larger area than other shaped nozzles. When carrying out large-area spraying operations, it can reduce the number of times the spray gun 3 needs to be moved and the spraying time, thereby improving work efficiency.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
