Referring to fig. 8, an embodiment of the present application provides a method for applying wall tiles of different sizes, which can be implemented using the above-mentioned application robot and the application mechanism used, i.e., reference is made to the structural components of the application robot and the application mechanism described above for structural components used in the steps of the method.

Specifically, the paving method compatible with the wall bricks with different sizes comprises the following steps:

s100: grabbing the wall brick 200 to be laid by the pick-up unit 20;

s200: the mechanical arm drives the wall brick 200 to be paved to move to the area to be paved;

s300: the movement detection unit 30 works and feeds back the information of the corners of the wall bricks 200 to be paved and the corners of the wall bricks 300 to be paved, the information of one side of the wall bricks 200 to be paved and one side of the wall bricks 300 to be paved to the controller, and the controller controls the mechanical arm to drive the wall bricks 200 to be paved to adjust the position according to the information fed back by the movement detection unit 30;

s400: when the wall brick 200 to be paved is adjusted in place, the first image detection module 50 can recognize that the corner of the wall brick 200 to be paved and the corner of the wall brick 300 to be paved form a cross joint, and the second image detection module 60 can recognize that one side edge of the wall brick 200 to be paved and one side edge of the wall brick 300 to be paved form a transverse joint;

s500: the robotic arm moves the wall brick 200 forward to lay the wall brick 200 in place.

The cross and transverse slits in fig. 5 and 7 are shown to be relatively wide, and do not represent actual placement such as leaving a particularly large slit, but are shown exaggerated in width for ease of reference to positional relationships and slit shapes.

In the step of gripping the wall brick 200 to be laid by the pick-up unit 20:

the extending direction of the center line of the base 10 is perpendicular to the preset direction, and the center line of the base 10 is parallel to the center line of the wall brick 200 to be paved and has a distance in the preset direction, so that the projection of one side of the base 10 in the preset direction on the wall brick 200 to be paved does not exceed the edge of the wall brick 200 to be paved. By eccentrically fixing the wall brick 200 to be laid, interference between the base 10 and the external environment can be avoided.

In the steps that the movement detection unit 30 works and feeds back the information of the corners of the wall bricks 200 to be paved and the corners of the wall bricks 300 to be paved to the controller, and the controller controls the mechanical arm to drive the wall bricks 200 to be paved to adjust the position according to the information fed back by the movement detection unit 30, wherein the information of one side of the wall bricks 200 to be paved and one side of the wall bricks 300 to be paved is:

the controller controls the driving module to drive the second image detection module 60 to move according to the size of the wall brick 200 to be paved, so that the projection of the second image detection module 60 on the wall brick 200 to be paved does not exceed the edge of the wall brick 200 to be paved. Through the eccentric fixation of the wall brick 200 to be paved, the interference between the second image detection module 60 and the external environment can be avoided, so that the paving safety is improved, and the second image detection module 60 is prevented from being broken.

In the step of controlling the driving module to drive the second image detection module 60 to move by the controller according to the size of the wall brick 200 to be laid:

the controller is preset with preset size data of the non-integral wall bricks 200 to be paved, the mobile detection unit 30 can acquire actual size data of the wall bricks 200 to be paved, the controller compares the actual size data with the preset size data for analysis, the controller directly controls paving bricks when the actual size data accords with the preset size data, and controls stopping paving bricks and giving an alarm when the actual size data does not accord with the preset size data. The preset size data can be derived from BIM data, the preset size data can be a range value, and as long as the actual size data is in the range, the size of the area to be paved is matched with the block of non-integral bricks, the gap between the wall bricks and the side wall surface after paving accords with the preset range, and the block of non-integral bricks can be used for paving.

In the step of driving the wall brick 200 to be laid to move to the area to be laid by the mechanical arm:

the controller obtains the inclination angle of the wall brick 200 to be paved and the wall surface, obtains the distance between the wall brick 200 to be paved and the wall brick 300 to be paved in the front-back direction, and controls the mechanical arm to drive the wall brick 200 to be paved to adjust the posture so that the wall brick 200 to be paved and the wall brick 300 to be paved are parallel. By adjusting the attitude before paving, the paved wall bricks and other paved wall bricks 300 can be kept neat, and reworking is avoided.

The principle of this embodiment is:

in the prior art, a robot capable of paving tiles can only pave tiles of full size, and for tiles of incomplete size or called incomplete tiles with a length of less than 600mm, the paving work still needs to be completed manually. In addition, robots that can accommodate tiles of 300 x 600 size often cannot be used for smaller tile placement, and still require manual work to place smaller tiles. Therefore, the application range of the general robot is small, obvious economic benefit cannot be brought, market competitiveness cannot be improved, and a large amount of paving work still needs to be carried out manually. In particular, when a wall is to be laid, for example, from left to right, a general robot interferes with the right wall surface in space when the wall is laid to the right, and the robot cannot be used for laying the edge wall bricks. In view of the above, the present application provides a paving mechanism 100, which is mounted on a mechanical arm of a paving robot, and is assisted by a paving method compatible with wall bricks of different sizes, so as to improve the corresponding problems.

Referring to fig. 4 and 5, when the paving robot of the present application uses the paving mechanism 100, the paving mechanism 100 is eccentrically disposed with respect to the wall tile (i.e., the center line of the base 10 is offset from the center line of the wall tile), so that the movement range of the first image detection module 50 can cover the corner position of the wall tile 200 to be paved, which is fixed by the vacuum chuck, to obtain the information of the corner of the wall tile 200 to be paved. When the eccentricity is fixed, the amount of the eccentricity is reduced as much as possible on the premise that the movement range of the first image detection module 50 can be ensured to cover the corner position of the wall brick 200 to be paved, which is fixed by the vacuum chuck, so that the stress of the wall brick 200 to be paved during paving is more uniform.

After the first image detection module 50 is moved to the corner, the mechanical arm drives the wall brick 200 to be paved to move to the area to be paved, and can drive the wall brick 200 to be paved to rotate around the Z axis shown in fig. 4, so that the left corner of the wall brick 200 to be paved and the corner of the paved wall brick can form a cross joint. Meanwhile, the second image detection module 60 may recognize information between the lower side of the wall brick 200 to be laid and the upper side of the underlying wall brick 300 to be laid and confirm whether a transverse seam is formed. When the cross joint and the transverse joint are both formed, the movement of the wall brick 200 to be paved can be confirmed, and at the moment, the wall brick 200 to be paved can be directly pushed forward by means of the mechanical arm so as to complete the paving work.

Further, in order to make the stress of the wall brick 200 to be paved more uniform during paving, namely, the wall brick 200 to be paved and the wall surface can be kept parallel, the application is also provided with the inclination sensor 80, the pitching angle of the wall brick 200 to be paved relative to the wall surface can be detected, and the wall brick 200 to be paved can be driven by the mechanical arm to rotate around the X axis shown in fig. 4, so that the wall brick 200 to be paved is adjusted to be parallel to the wall surface.

In order to make the wall bricks after being paved flush with the top surface of the wall brick already paved below (i.e. the upper surface of the wall brick 200 to be paved in fig. 4 can be flush with the upper surface of the wall brick 300 already paved in fig. 5), the embodiment is provided with two displacement sensors 90, the displacement sensors 90 can respectively detect the displacement of two detection points relative to the wall brick 300 already paved, determine whether the posture before being paved is in place, and if the displacement data detected by the two displacement sensors 90 do not correspond, the wall brick 200 to be paved can be driven to rotate around the Y axis shown in fig. 4 by a mechanical arm so that the displacement data detected by the two displacement sensors 90 can correspond to each other to further adjust the posture of the wall brick 200 to be paved so that the wall brick 200 to be paved can be parallel to the wall brick 300 already paved below.

After finishing each position adjustment and posture adjustment, the mechanical arm can drive the wall brick 200 to be paved to move towards the wall surface so as to finish paving. Since the second image detection module 60 and the base 10 do not exceed the right edge of the wall brick 200 to be laid, the second image detection module will not interfere with the right wall surface, and the installation can be normally completed without manually laying the wall bricks at the edges. And because the wall brick 200 to be paved is eccentrically fixed, the second image detection module 60 can acquire information without moving to the right corner of the wall brick 200 to be paved, compared with a common robot, the positioning step which needs to be performed for ensuring non-eccentricity during grabbing and the detection step for the right corner are reduced, unnecessary steps are reduced for the whole paving step, paving time is shortened, and efficiency is higher. In addition, under the premise of ensuring eccentricity and reducing the eccentric amount as much as possible, the embodiment adopts a double camera to observe the alignment of the left and right corner brick angles and the adjacent bricks, so that when the upper and lower bricks have deviation, the attractive influence caused by the fact that the errors are averaged to two sides can not be reduced, the brick joint is more attractive, and the brick joint is basically kept at 1.5mm.

Referring to fig. 6 and 7, when the wall bricks of incomplete size are laid, the process is identical to the above process, and the main difference is that the second telescopic module 42 on the right side makes the extension length of the second image detection module 60 different so as to avoid interference with the right side wall surface. The specific length of movement of the second image detection module 60 may be specifically determined based on the specific length dimension of the incompletely sized wall tiles.

When the wall brick to be laid is a small-sized wall brick, the left side of the base 10 may protrude from the left side of the wall brick as in fig. 7, so that the fixing of the small-sized wall brick can be completed. And repeating the above-described paving process to become a paving, the length of the base 10 may be designed to be about 300mm, so that the paving mechanism 100 may cover wall tiles substantially below 300mm, satisfying the wall tile paving work of most projects.

It will be appreciated that the above-mentioned full-size, incomplete-size and small-size wall tiles are applied from left to right by way of example, with the left-side image detection module as the first image detection module 50 and the right-side image detection module as the second image detection module 60. When the wall bricks are paved from right to left, the paving process of the leftmost wall bricks can refer to the above process, the image detection module on the right side is the first image detection module 50, and the image detection module on the left side is the second image detection module 60, and the paving process is in a symmetrical relationship, so that the description is omitted.

In summary, according to the paving mechanism 100 of the present application, through the cooperation of the driving module, the first image detection module 50 and the second image detection module 60, the corner information and the side information of the wall brick 200 to be paved, which is eccentrically fixed by the pick-up unit 20, can be obtained, and by comparing the corner information and the side information of the wall brick 300 to be paved, the accurate positioning of the wall brick 200 to be paved can be completed, so that the paving robot applying the paving mechanism 100, after combining the corresponding paving methods compatible with wall bricks of different sizes, can perform paving on the wall bricks of full size, and also can perform paving on the wall bricks of incomplete size and small size, thereby expanding the coverage rate of automatic paving, and having higher economic benefit and stronger competitiveness.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
