The glue scraping assembly 200 can adjust the glue scraping thickness according to the protrusion and recess information. For example, when a certain position on the wall is recessed by 1 mm, the glue scraping thickness of a position on the corresponding wall tile and corresponding to the position increases by 1 mm. When a certain position on the wall is protruded by 1 mm, the glue scraping thickness of a position on the corresponding wall tile and corresponding to the position decreases by 1 mm.
In this embodiment, the glue scraping assembly 200 includes a depth camera and a first controller 101. The depth camera is electrically connected to the first controller 101. The first controller 101 is electrically connected to the glue scraping assembly 200. The depth camera can shoot the wall and send data acquired through shooting to the first controller 101. The first controller 101 processes the data shot through the depth camera so as to acquire the protrusion and recess information. Additionally, according to the protrusion and recess information, the first controller 101 can control the glue scraping assembly 200 to scrape glue on the wall tile so that the glue scraping thickness matches the protrusion and recess situation of the wall. For example, when a position on the wall is recessed, correspondingly, the glue scraping thickness of a position on the wall tile and attached to the position increases and forms a protrusion to fill the recess. When a position on the wall is protruded, correspondingly, the glue scraping thickness of a position on the wall tile and attached to the position decreases and forms a recess so that glue is totally attached to the wall in completion of paving. In brief, for a protrusion position on the wall, glue on the wall tile and corresponding to the position is recessed. For a recess position on the wall, glue on the wall tile and corresponding to the position is protruded.
In an embodiment, as for the manner of acquiring the protrusion and recess information of the wall, the protrusion and recess information may be acquired by the first controller 101 processing the data shot by the depth camera. Additionally, the protrusion and recess information may also be acquired through an external device (for example, a measuring robot), then transmitted through a network to a controller in a wall tile paving robot, and transmitted by the controller to a first detection unit 100 in the wall tile paving robot. Alternatively, the first detection unit 100 is a part of the controller. The external device transmits the protrusion and recess information through the network to the first detection unit 100.
In an embodiment, as for the manner of acquiring the protrusion and recess information of the wall, wall protrusion and recess data measured by an external measuring device are transmitted to the first detection unit 100; alternatively, the protrusion and recess information may also be the information detected by the first detection unit 100 of a machine.
For example, a detection unit may be a product capable of implementing three-dimensional measurement and imaging technology, for example, a measuring robot existing in the market.
In an embodiment, the glue scraping assembly 200 includes a laser sensor and a first controller 101. The first controller 101 is electrically connected to the laser sensor. The first controller 101 is electrically connected to the glue scraping assembly 200. The laser sensor scans the wall and sends data acquired through scanning to the first controller 101. The first controller 101 processes the data scanned through the laser sensor so as to acquire the protrusion and recess information.
In this embodiment, the distance between the glue scraping assembly 200 and the wall tile is adjustable so as to adjust the glue scraping thickness. When the glue scraping assembly 200 is close to the wall tile, more glue is scraped, resulting in a relatively small glue thickness on the wall tile. When the glue scraping assembly 200 is away from the wall tile, less glue is scraped, resulting in a relatively large glue thickness on the wall tile.

In some embodiments, the number of scrapers 220 may not correspond to the number of drive members 210. For example, the number of drive members 210 is greater than the number of scrapers 220. Multiple drive members 210 drive one scraper 220 to act simultaneously. In another example, the number of drive members 210 is smaller than the number of scrapers 220. One drive member drives multiple scrapers 220 to act simultaneously.
In an embodiment, the glue scraping assembly 200 includes a lifting structure and the scrapers 220. The wall tile is secured on the lifting structure. The scrapers 220 are located above the wall tile. When glue scraping is performed, the first controller 101 controls the drive members 210 to act so that the scrapers 220 get close to or away from the wall tile to modify the glue scraping thickness in a corresponding position. For example, when a protrusion exists on the wall, the first controller 101 controls the lifting structure to act to make the wall tile get close to the scrapers 220 so that the glue scraping thickness matches the protrusion on the wall after glue scraping is performed. When a recess exists on the wall, the first controller 101 controls the lifting structure to act to make the wall tile get away from the scrapers 220 so that the glue scraping thickness matches the recess on the wall after glue scraping is performed.
In this embodiment, before glue scraping is performed, glue with the maximum thickness satisfying the protrusion and recess information is spread on the wall tile first In this case, when glue scraping is performed, the first controller 101 controls the drive members 210 to extend and retract to complete glue scraping.

In this embodiment, the second detection unit 280 is installed on the second bracket 400. The second detection unit 280 is located on one side where the glue spreading assembly 300 is located. The second detection unit 280 detects the glue thickness in a position where glue scraping is to be performed so that the glue spreading thickness is acquired. The first controller 101 is electrically connected to the second detection unit 280. The first controller 101 is electrically connected to the drive members 210. The first controller 101 is electrically connected to the glue spreading assembly 300. The second detection unit 280 transmits the acquired glue spreading thickness to the first controller 101. When the glue spreading thickness is unable to satisfy the glue scraping thickness determined according to the protrusion and recess information, the first controller 101 controls the glue spreading assembly 300 to spread glue so as to increase the glue thickness. When the glue spreading thickness is able to satisfy the glue scraping thickness determined according to the protrusion and recess information, the first controller 101 controls the drive members 210 to drive the scrapers 220 to scrape glue according to the glue scraping thickness determined according to the protrusion and recess information. After the first controller 101 processes the glue spreading thickness and the protrusion and recess information, the first controller 101 controls the glue spreading assembly 300 to supplement glue when the glue spreading thickness is unable to satisfy the requirement of the glue scraping thickness. When the glue spreading thickness is found to be able to satisfiy the requirement of the glue scraping thickness, the first controller 101 controls the drive members 210 to act and complete glue scraping.
When the glue spreading thickness is unable to satisfy the glue scraping thickness determined according to the protrusion and recess information, it indicates that the glue amount on the wall tile is insufficient and cannot match a protrusion or recess on the wall after glue scraping is performed. In this case, the first controller 101 controls the glue spreading assembly 300 to spread and supplement glue until the glue spreading thickness is able to satisfy the glue scraping thickness determined according to the protrusion and recess information. When the glue spreading thickness is able to satisfy the glue scraping thickness determined according to the protrusion and recess information, it indicates that glue on the wall tile is able to satisfy the requirement of the glue scraping thickness after glue scraping is performed. In this case, the first controller 101 controls the drive members 210 to drive the scrapers 220 to scrape glue based on the glue scraping thickness, guaranteeing that the protrusion and recess situation of glue on the wall tile matches the protrusion and recess situation of the wall.
In an embodiment, the second detection unit 280 is a laser distance sensor. The laser distance sensor detects a height (thickness) difference of the wall tile before and after glue spreading is performed, thereby acquiring the glue spreading thickness. The second detection unit 280 may also be, for example, a three-dimensional (3D) scanning device.

Embodiments of the present application provide a glue scraping mechanism 10. The glue scraping mechanism 10 includes a first detection unit 100 and a glue scraping assembly 200. The first detection unit 100 is electrically connected to the glue scraping assembly 200. The first detection unit 100 is configured to acquire the protrusion and recess information of a wall. The glue scraping assembly 200 is configured to be able to adjust glue scraping thickness according to the protrusion and recess information. The glue scraping assembly 200 includes a plurality of drive members 210, and a plurality of scrapers 220 disposed side by side. The drive members 210 are in one-to-one correspondence to the scrapers 220. The drive members 210 are electrically connected to the first detection unit 100. The drive members 210 are used for driving the scrapers 220 to get close to or away from a wall tile to modify the glue scraping thickness. The glue scraping mechanism 10 includes a glue spreading assembly 300. The glue spreading assembly 300 is electrically connected to the first detection unit 100. The glue spreading assembly 300 is used for spreading glue on the wall tile. The glue spreading assembly 300 is configured to be able to perform a glue supplement on the wall tile according to the protrusion and recess information in a glue scraping process. The glue scraping mechanism 10 includes a second detection unit 280. The second detection unit 280 is electrically connected to the glue spreading assembly 300. The second detection unit 280 is configured to detect the glue spreading thickness of the wall tile. The glue spreading assembly 300 is configured to be able to perform the glue supplement on the wall tile according to the protrusion and recess information and the glue spreading thickness in the glue scraping process.

When the wall tile is secured under the first bracket 700 by the wall tile clamp 600, the drive assembly 500 starts to drag the glue spreading assembly 300 to move from one end away from the first motor to one end close to the first motor. The glue spreading assembly 300 performs preliminary spreading. When the glue spreading assembly 300 reaches one end close to the first motor, the drive assembly 500 starts to drag the glue spreading assembly 300 and the glue scraping assembly 200 to move from one end close to the first motor to one end away from the first motor. The glue scraping assembly 200 starts to scrape glue according to the protrusion and recess information. When the first controller 101 determines that the glue thickness before the scrapers 220 is sufficient, the glue spreading assembly 300 does not act. When the first controller 101 determines that the glue thickness before the scrapers 220 is insufficient, the glue spreading assembly 300 acts and starts to spread glue so as to increase the glue thickness. In a process where the glue spreading assembly 300 returns to an original position, the drive members 210 drive the scrapers 220 to scrape glue according to the protrusion and recess information. When the scrapers 220 cross an edge of the wall tile, glue scraping is completed. In the glue scraping process, the side glue scraping plate 240 automatically scrapes the glue inside the first bracket 700.
The glue scraping mechanism 10 acquires the protrusion and recess information of the wall through the first detection unit 100 and adjusts the glue scraping thickness of the wall tile according to the protrusion and recess information so that the wall tile is totally attached to the wall in completion of paving, guaranteeing a pasting effect and achieving a relatively low hollowing rate. The arrangement of the glue spreading assembly 300 helps supplement glue for the wall tile. When glue on the wall tile is unable to satisfy the requirement of the glue scraping thickness, the glue spreading assembly 300 may supplement glue. With the arrangement of the glue blocking plate 260, the accumulated glue is blocked when being in contact with the glue blocking plate 260. Under the action of the glue blocking plate 260, the accumulated glue falls back onto the wall tile, preventing an excessive glue accumulation from affecting the detection of the glue spreading thickness performed by the second detection unit 280.

In an embodiment, the tile laying assembly 830 is a platform for placing the wall tile. The platform may be provided with a baffle plate to limit the movement of the tile.
This embodiment further provides a wall tile paving method. The wall tile paving method includes extracting a point cloud of wall information, acquiring protrusion and recess information of a wall, converting the protrusion and recess information of the wall into glue thickness information, and spreading and scraping glue according to the glue thickness information. The wall tile paving method is used for scraping glue. The glue thickness on a wall tile matches the protrusion and recess situation of the wall. In the completion of paving, the wall tile is closely attached to the wall.
When the glue is spread and scraped according to the glue thickness information, the glue thickness on the wall tile is monitored in real time. In response to glue spreading thickness being unable to satisfy the glue thickness determined according to the protrusion and recess information, the glue spreading thickness is increased through a glue supplement. In response to the glue spreading thickness being able to satisfy the glue thickness determined according to the protrusion and recess information, redundant glue is scraped. It guarantees through the glue supplement operation that the glue thickness on the wall tile can satisfy the glue thickness determined according to the protrusion and recess information.
Embodiments of the present application provide a glue scraping mechanism with an aim of solving the problem that a wall tile is prone to be hollow or is pasted insecurely when a wall is rough and uneven in the related art.

When the drive members drive the scrapers to get close to the wall tile, the glue thickness decreases. When the drive members drive the scrapers to get away from the wall tile, the glue thickness increases to implement the adjustment of the glue scraping thickness.
In an embodiment, the glue scraping mechanism includes a drive assembly and a first bracket. The glue scraping assembly is slidably connected to the first bracket. The drive assembly is configured to drive the glue scraping assembly to reciprocate. The arrangement of the drive assembly helps the drive assembly to reciprocate relative to the first bracket.
