Description

Technical Field

[0001] This utility model belongs to the field of construction machinery technology, specifically relating to an automatic tile grouting robot. Background Technology

[0002] In building decoration and renovation projects, ceramic tiles are widely used due to their wear resistance, ease of cleaning, and aesthetic appeal. To accommodate the thermal expansion and contraction characteristics of cement mortar and ceramic tiles themselves, a uniformly wide gap must be left when laying adjacent tiles. At the same time, this gap can also prevent tiles from cracking due to uneven stress and reduce the penetration of stains into the bottom of the tiles. Therefore, the gap needs to be filled with grout (i.e., "grout sealing").

[0003] In existing technologies, tile grouting is entirely done manually. The specific process includes: 1. Pre-treatment stage: Manually using tools to clean loose impurities, dust, and water from the gaps to ensure they are dry and clean. Incomplete cleaning in this step will directly lead to poor adhesion between the grout and the gap walls, making it prone to falling off; 2. Adhesive preparation stage: Manually mixing solid grout with water in a certain proportion, stirring until a paste without lumps is formed. The uniformity of stirring depends entirely on the worker's experience. Uneven stirring will result in insufficient strength or color difference after the adhesive cures; 3. Filling stage: Manually filling the gaps with adhesive using a scraper or caulking gun. During the filling process, uneven application of force can easily lead to incomplete filling or overflow of adhesive; 4. Surface cleaning stage: Manually wiping the surface of the tiles with a damp cloth or sponge to remove any remaining adhesive. If cleaning is not timely, the adhesive will harden on the tile surface, requiring additional cleaning with a special solvent, adding to the work process.

[0004] The aforementioned manual grouting method has significant drawbacks: First, it is highly dependent on the skill level and experience of the workers. Differences in the operating techniques of different workers can lead to unstable grouting quality, such as uneven filling of gaps, poor surface flatness, and easy damage to the adhesive at cross joints (where tiles meet). Second, the work efficiency is low, with a single person only able to complete grouting work on approximately 20-30 square meters of tiles per day, which is insufficient to meet the time requirements of large-scale renovation projects. Third, labor costs are high, accounting for approximately 8%-12% of the overall renovation cost, increasing the total project cost. Fourth, the working environment affects the health of workers, as the volatile components in the grout adhesive can easily irritate the respiratory tract, posing health risks with long-term exposure.

[0005] Currently, there is no equipment in the industry that can automate the entire process of "film application - adhesive application - adhesive scraping - obstacle avoidance". Some semi-automatic equipment can only complete a single adhesive application or scraping action, still requiring manual assistance for positioning, cleaning, and obstacle avoidance, which cannot fundamentally solve the pain points of manual tile grouting. Therefore, developing an automatic tile grouting device that can move autonomously along the grout lines, automatically avoid obstacles, and simultaneously complete film application and precise adhesive application has become the key to solving the existing technical problems. Summary of the Invention

[0006] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide an automatic tile grouting robot.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An automatic tile grouting robot includes a mobile cart and a film-applying mechanism and an adhesive-applying mechanism that can follow the mobile cart and move along the tile gaps. The film-applying mechanism is configured to apply a separable film adapted to the tile gaps on the tile surface along the moving direction. The adhesive-applying mechanism is configured to introduce grout into the tile gaps along the moving direction. The mobile vehicle includes: Vehicle body; The detection device is fixed on the vehicle body and is used to detect whether there is an obstacle avoidance area on the forward movement path of the mobile vehicle; A multi-wheeled walking device includes wheel sets respectively disposed on both sides of the vehicle body.

The obstacle avoidance movement includes moving in the opposite direction of the mobile vehicle to allow at least three wheels to successively lift over the obstacle avoidance area.

[0008] Preferably, the detection device includes a center detector and an edge detector respectively fixed to the middle and both sides of the vehicle body. The center detector is used to make the moving path of the mobile trolley coincide with the gap between the tiles. The edge detector is used to detect the distance between any of the wheels and the edge of the obstacle avoidance area.

[0010] Preferably, the swing adjustment component further includes a fixed rod fixedly installed on the vehicle body, and a drive cylinder is rotatably connected between the fixed rod and the swing frame, with the drive cylinder and the wheel distributed on both sides of the rotation center of the swing frame.

[0011] Preferably, the film-applying mechanism includes a film storage roller, a film-applying roller, a film-cutting knife, and a film-pressing roller arranged sequentially along the film conveying direction; the film storage roller is configured to release film to the film-applying roller, the film storage roller and the film-applying roller are both rotatably mounted on a rotatable first rotating frame, the film-pressing roller is rotatably mounted on a rotatable second rotating frame, and the film-cutting knife is mounted on the telescopic drive end of the film-cutting cylinder.

[0012] Preferably, the film-applying mechanism further includes a film-cutting ring blade sleeved outside the film-pressing roller, the film-cutting ring blade being detachably connected to the second rotating frame via a blade holder.

[0013] Preferably, the cutting ring cutter has two blades symmetrically distributed on both sides of the cutter holder, and the distance between the two blades is equal to the width of the gap between the tiles.

[0014] Preferably, the glue application mechanism includes a lifting drive component and an automatic glue gun and a glue scraper mounted on the lifting drive component.

[0015] Preferably, the automatic glue gun includes a base and an electric push rod and a glue cylinder mounted on the base. A piston is slidably fitted inside the glue cylinder, and a connecting rod connects the piston and the electric push rod.

[0016] Preferably, the scraper includes a fixed part and an extension part connected by an arc transition. The fixed part is fixed to the bottom of the base and has a through hole that can pass through the glue tube nozzle. The extension part has a scraping blade for scraping off the grout material protruding from the tile surface inside and outside the gap between tiles.

[0017] Compared with the prior art, this utility model has the following advantages: (1) In this utility model, the cooperation of the mobile trolley, the film application mechanism and the glue application mechanism replaces manual grouting, which can realize the film application, glue application and glue scraping operations in a fully automated manner, thereby effectively reducing labor costs and improving grouting efficiency.

[0023] like Figure 1 As shown, the present invention provides an automatic tile grouting robot, comprising a mobile trolley 1 and a film-applying mechanism 2 and an adhesive-applying mechanism 3 capable of moving along the tile gaps with the mobile trolley 1. Specifically, the mobile trolley 1 is the base of the entire robot, providing the power for the robot's automatic movement. The film-applying mechanism 2 applies a separable film adapted to the tile gaps on the tile surface along the moving direction. The adhesive-applying mechanism 3 introduces grout into the tile gaps along the moving direction.

[0024] Continue to refer to Figure 2 As shown, the mobile vehicle 1 includes a vehicle body 11, a detection device 12, and a multi-wheeled walking device 13. Specifically, the detection device 12 provides visual guidance for the automatic movement of the entire mobile vehicle 1 through visual detection, and detects whether there are obstacle avoidance areas on the forward movement path of the mobile vehicle 1 during its movement; the multi-wheeled walking device 13 moves automatically along the planned path, and can automatically avoid the obstacle avoidance areas.

[0025] For example, regarding tile grout sealing, during the tile laying process, the joints at the corners of the tiles will form... Figure 11The cross-shaped seam shown is the obstacle avoidance area on the moving path of the mobile trolley 1. Without this obstacle avoidance area, when the mobile trolley 1 moves along one of the seams and passes the cross-shaped seam, its wheels will press vertically over the other seam. If the other seam already contains sealant, the wheels will directly press on the sealant and / or the film containing it, affecting the sealant quality and causing sealant residue to adhere to the wheel surface, accelerating wheel damage. Therefore, the multi-wheeled walking device 13 of this invention, in conjunction with the detection device 12, can automatically avoid the obstacle avoidance area. In this example, the detection device 12 includes a center detector 121 and an edge detector 122 respectively fixed to the middle and both sides of the vehicle body 11. Specifically, the center detector 121 is used to make the moving path of the mobile cart 1 coincide with the gap between the tiles, thereby ensuring the accuracy of the moving cart 1 moving along the gap; the edge detector 122 is adapted to the multi-wheel walking device 13.

[0026] In this example, the multi-wheeled walking device 13 includes wheel sets respectively disposed on both sides of the vehicle body 11, and correspondingly, the edge detector 122 is also fixed on both sides of the vehicle body 11. Specifically, each wheel set includes at least three wheels 131, and each wheel 131 is connected to the vehicle body 11 through a swing adjustment member 132. Figure 1 and Figure 2 The image shows a structural example with four wheels 131.

[0027] The swing adjustment component 132 includes, for example: Figure 3 The diagram shows a swing frame 133 rotatably mounted on the vehicle body 11 and a fixed rod 135 fixedly mounted on the vehicle body 11. The swing frame 133 includes a rotation center and free ends located on both sides of the rotation center. One free end is equipped with a wheel 131 and a motor 134 for driving the wheel 131 to rotate. The other free end is rotatably connected to the fixed rod 135 with a drive cylinder 136. Based on this, the swing frame 133 can be driven to rotate by the extension and retraction of the drive cylinder 136. As the rotation angle of the swing frame 133 varies, the height at which the wheel 131 is positioned also varies. Under this limitation, when the edge detector 122 detects that the distance between the wheel 131 and the edge of the obstacle avoidance area is less than a threshold, it activates the drive cylinder 136 so that the overall swing adjustment component 132 can drive the wheel 131 to swing and lift, preventing the wheel from directly rolling into the obstacle avoidance area (cross joint).

[0028] For example, the mobile cart 1 is in accordance with Figure 11 The status shown indicates that it is in use and should be followed. Figure 1 The arrows indicate forward or backward movement. The multi-wheeled walking device 13 in the diagram includes four wheels 131 (a / b / c / d). The edge detector 122 adaptively detects the distance between the four wheels 131 and the edge of the obstacle avoidance area. Taking the forward movement of the mobile vehicle 1 as an example, the four wheels 131 approach the edge of the obstacle avoidance area in the order a / b / c / d. Therefore, the order in which the four wheels 131 are lifted under the drive of the corresponding swing adjustment member 132 should also be abcd (opposite to the forward direction). When any one of the wheels 131 crosses the obstacle avoidance area, and the distance between that wheel 131 and the edge of the obstacle avoidance area is greater than a threshold, under the drive of the swing adjustment member 132, that wheel 131 resets and swings down, thereby allowing that wheel 131 to once again provide support for the entire mobile vehicle 1. It is worth noting that the more wheels 131 there are, the better the stability of the entire mobile vehicle 1 when crossing the obstacle avoidance area. Considering the economic factors of the mobile vehicle 1, the number of wheels 131 is preferably 3 to 5.

[0029] Continue to refer to Figure 4 As shown, the film-applying mechanism 2 includes a film storage roller 21, a film-applying roller 22, a film-cutting knife 23, and a film-pressing roller 24 arranged sequentially along the film conveying direction. The figure shows the overall structure of the film-applying mechanism 2, including a basic mounting frame and a drive structure mounted on the mounting frame. This drive structure includes a rotating frame, a rotating motor, and a film-cutting cylinder. Specifically, the film storage roller 21 and the film-applying roller 22 are arranged in a... Figure 5 The first rotating frame is rotatably mounted on the mounting frame and driven by a first rotating motor. The oscillation of the first rotating frame ensures that the film-applying roller 22 contacts the tile surface during film application. The film storage roller 21 is configured to release film onto the film-applying roller 22. The second rotating frame is rotatably mounted on the mounting frame and driven by a second rotating motor. After the film is applied to the tile surface by the film-applying roller 22, the second rotating frame oscillates, causing the pressure roller 24 to press firmly against the film surface, ensuring stable film adhesion and preventing accidental film detachment. The film-cutting knife 23 is mounted on the extension / retraction drive end of the film-cutting cylinder. After film application, the film-cutting cylinder drives the film-cutting knife 23 to cut the film between the film-applying roller 22 and the pressure roller 24. Furthermore, after film application, the entire film-applying mechanism 2 can be reset by rotating the rotating frame and retracting the film-cutting cylinder.

[0030] For example, when applying the film as described above, ensure that the center of the film is aligned with the center of the tile gap, meaning that after the film is applied by the film roller 22, it can completely cover the tile gap. To ensure the tile gap remains visible afterward, it is preferable to... Figure 6 As shown, a cutting ring blade 25 is fitted outside the pressing roller 24. The cutting ring blade 25 is detachably connected to the second rotating frame via a blade holder. Based on this, while the pressing roller 24 presses the attached film firmly, the cutting ring blade 25 also cuts away the film at its center (the position corresponding to the tile gap), thus exposing the tile gap. It is worth noting that the cutting ring blade 25 has the following characteristics... Figure 7 The two blades, symmetrically distributed on both sides of the blade holder, are spaced apart by a distance equal to the width of the gap between the tiles. This ensures that the width of the slit cut by the cutting ring blade 25 on the film is equal to the width of the gap between the tiles. Furthermore, the blade holder and the second rotating frame are detachably connected by bolts, facilitating the replacement of the cutting ring blade 25 according to the actual width of the gap between the tiles.

[0031] Continue to refer to Figure 8 As shown, the glue application mechanism 3 includes a lifting drive component 31 and an automatic glue gun 32 and a glue scraper 33 mounted on the lifting drive component 31. Specifically: The automatic glue gun 32 includes, for example: Figure 9 The diagram shows a base 321 and an electric push rod 322 and a glue cylinder 323 mounted on the base 321. A piston 324 slides within the glue cylinder 323, and a connecting rod 325 connects the piston 324 and the electric push rod 322. Therefore, the extension and retraction of the electric push rod 322 drives the connecting rod 325 and the piston 324 to move along the axis of the glue cylinder 323, thereby extruding the grout stored in the glue cylinder 323 from the nozzle at the front end of the glue cylinder 323. It is worth noting that the nozzle at the front end of the glue cylinder 323 should be aligned with the gap between the tiles, and the central axis of the nozzle should be in the same plane as the center line of the gap between the tiles. This ensures that the grout fully fills the gap between the tiles and avoids voids in the grout.

[0032] The scraper 33 includes, for example, the scraper blade 33. Figure 10 The fixed part 331 and the extension part 332 are connected by an arc transition. The fixed part 331 is fixed to the bottom of the base 321 and has a through hole that can pass through the glue tube 323 nozzle. The extension part 332 has a scraper blade 333 for scraping off the grout material protruding from the tile surface inside and outside the gap between the tiles.

[0033] In summary, the steps for the robot to perform automatic seam sealing provided by this utility model include: S1. Film Application: The moving trolley 1 moves along the tile gaps, while the adhesive application mechanism 3 remains positioned at its highest point (not activated). The film application mechanism 2 applies a detachable film, adapted to the tile gaps, to the tile surface along the moving direction, and then cuts off the portion of the film covering the tile gaps to ensure the gaps are exposed. This step ensures that film is applied to both sides of the tile gaps and precisely matches the cross-joint positions.

[0034] S2. Filling and Scraping: After completing the application of grout to all the tile gaps in the required grouting area, the moving trolley 1 moves along the tile gaps. The lifting drive component 31 drives the automatic caulking gun 32 and the scraper 33 to descend, causing the scraper blade 333 of the scraper 33 to adhere to the tile surface. The automatic caulking gun 32 introduces grout into the tile gaps along the moving direction, while the scraper 33 scrapes away any grout protruding from the tile surface inside and outside the tile gaps. In this step, during the movement of the moving trolley 1, the detection device 12 and the multi-wheel walking device 13 cooperate to activate the obstacle-avoiding movement mode for the obstacle avoidance area (cross joints), thereby ensuring that each tile gap is filled with high-quality grout and avoiding interference between the movement of the moving trolley 1 and the grout filling in the obstacle avoidance area (cross joints).

[0035] S3. Reset all robot structures and manually remove the film attached in step S1.

[0036] Furthermore, when the robot of this utility model moves in a different direction, it rotates at a differential speed through the multi-wheel walking device 13 on both sides of the vehicle body 11, thereby facilitating the adjustment of the robot's operating direction and making it suitable for comprehensive treatment of gaps between tiles in various locations.

[0037] This utility model's automatic grouting robot, through the cooperation of a moving trolley 1, a film-applying mechanism 2, and an adhesive-applying mechanism 3, replaces manual grouting, and can fully automate operations such as film application, adhesive application, and adhesive scraping, thereby effectively reducing labor costs and improving grouting efficiency.
