Description

TECHNICAL FIELD

The present disclosure relates to the technical field of construction equipment and, in particular, to a fluid laying device, a floor tile laying robot, and a slurry laying method.

BACKGROUND

At present, when floor tiles are laid, a layer of adhesive fluid needs to be laid on a paving surface to effectively bond the tiles and the paving surface together. Generally, the adhesive fluid is manually spread on the paving surface, and then the fluid is scraped into a straight surface with a scraper. Due to the influence of the worker's proficiency factor, it is easy to cause the laid slurry surface to be out of line. After the tiles are laid, it is easy to cause the lack of slurry under the tiles, leading to the quality problem of empty drum tiles. In addition, the method of manual scraping for the straight surface has high technical requirements for the worker and features high labor intensity, which is not conducive to improving the efficiency of the slurry laying operation.

For those of ordinary skill in the art, specific meanings of the preceding terms in the present disclosure may be construed according to specific circumstances.

A fluid laying device 100 in the embodiments of the present disclosure is described below with reference to the drawings.

As shown in FIG. 1, the fluid laying device 100 in an embodiment of the present disclosure is used in conjunction with a laser generator 200 and includes a chassis 10, a translation deviation correction mechanism 20, a slurry laying mechanism 30, and a slurry supply mechanism 40.

The translation deviation correction mechanism 20 is disposed on the chassis 10 and includes a movable base 23 configured to move in a direction perpendicular to a laying direction of fluid and a deviation correction detection member 24 disposed on the movable base 23. The slurry laying mechanism 30 is connected to the movable base 23. The slurry supply mechanism 40 is disposed on the chassis 10 to supply the fluid to the slurry laying mechanism 30. It is to be understood that the slurry laying mechanism 30 is disposed at a front end of the chassis 10. When the fluid laying device 100 works, the slurry supply mechanism 40 supplies the fluid to the slurry laying mechanism 30, the chassis 10 drives the fluid laying device 100 to linearly move as a whole, and the slurry laying mechanism 30 performs a slurry laying operation on a construction surface 300.

As shown in FIG. 5, when the fluid laying device 100 works, the deviation correction detection member 24 controls the movable base 23 according to received laser rays so that the slurry laying mechanism 30 performs slurry laying linearly along the laying direction. That is to say; when the slurry laying mechanism 30 works normally, a position of vertical laser rays O1 emitted by the laser generator 200 and received by the deviation correction detection member 24 is a vertical zero position; and the movable base 23 is configured to drive the slurry laying mechanism 30 to move so that the position of the vertical laser rays O1 received by the deviation correction detection element 24 can return to the vertical zero position. For example, in a process of laying tiles, the slurry laying mechanism 30 performs slurry laying linearly when working normally. Due to the influence of the operator's proficiency factor, the chassis 10 easily deviate from a slurry laying direction. For example, the slurry laying mechanism 30 deviates from the laying direction of the fluid to the left or the right (as shown in FIGS. 12 and 13), so that the linear slurry laying operation cannot be kept. When the position of the vertical laser rays O1 emitted by the laser generator 200 and received by the deviation correction detection member 24 is not at the vertical zero position, the translation deviation correction mechanism 20 is started, and the movable base 23 drives the slurry laying mechanism 30 to move in a direction perpendicular to a movement direction of the chassis 10, thereby adjusting the position of the slurry laying mechanism 30 so that the position of the vertical laser rays O1 received by the deviation correction detection member 24 returns to the vertical zero position, and thereby ensuring that a slurry surface laid by the slurry laying mechanism 30 is in a straight line. Optionally, the deviation correction detection member 24 may directly control the movable base 23 according to the received laser rays. Alternatively, a controller (not shown) is provided in the fluid laying device 100, the deviation correction detection member 24 converts the received laser rays into an electrical signal and transmits the electrical signal to the controller, and the controller controls the movable base 23 according to the electrical signal.

In the fluid laying device 100 in the embodiment of the present disclosure, the vertical laser rays O1 is used as a reference parallel to a floor tile edge line, and the deviation correction detection member 24 receives a signal of laser rays parallel to the floor tile edge line to control the translation deviation correction mechanism 20 to perform deviation correction on the slurry laying mechanism 30 in the horizontal direction. Due to ground flatness, sundries (such as gravel) and other reasons, the existing slurry laying robot cannot move along a straight line, and slurry laying cannot be performed linearly. In the present disclosure, it can be ensured that a laid slurry surface is linearly laid, and manual work can be replaced to complete laying of an adhesive fluid, thereby avoiding a quality problem caused by nonstandard manual operation, reducing the labor intensity of workers and improving the slurry laying efficiency.

In some embodiments, the deviation correction detection member 24 is a photoelectric position sensitive sensor.

In some embodiments, as shown in FIG. 2, the translation deviation correction mechanism 20 includes a drive member and a movement assembly. The drive member is disposed on the movable base 23. The movement assembly includes a moving part and a guide support connected to the moving part, where the moving part is drivingly connected to the drive member, and the guide support is connected to the chassis 10.

Specifically, the drive member is a first drive motor 21. The moving part is a lead screw 22, where the lead screw 22 is drivingly connected to an output end of the first drive motor 21. The guide support is a nut 25, where the nut 25 is fitted on the lead screw 22, and the nut 25 is connected to the chassis 10. When the translation deviation correction mechanism 20 works, the first drive motor 21 is started to drive the lead screw 22 to rotate, the lead screw 22 generates a thrust to the nut 25, and a reaction force applied by the nut 25 to the lead screw 22 drives the movable base 23 to perform translational movement, thereby driving the slur ty laying mechanism 30 to move horizontally to achieve translation correction. Since both the deviation correction detection member 24 and the slurry laying mechanism 30 are disposed on the movable base 23, the deviation correction detection member 24 can visually reflect the position of the slurry laying mechanism 30 by receiving the vertical laser rays O1 emitted by the laser generator 200, and the deviation correction detection member 24 moves on the movable base 23 along with the slurry laying mechanism 30 and can detect in real time whether the slurry laying mechanism 30 is in place after deviation correction.

Optionally, as shown in FIG. 2, a lead screw support base 26 is pivotally disposed at the other end of the lead screw 22 and connected to the movable base 23 so that the connection reliability between the lead screw 22 and the movable base 23 is enhanced, and a process in which the lead screw 22 drives the movable base 23 to move is more stable. One end of the lead screw 22 is drivingly connected to an output shaft of the first drive motor 21 through a coupling 27, thereby facilitating the installation of the lead screw 22 and the first drive motor 21.

Optionally, the lead screw 22 is a ball screw. Of course, the lead screw 22 in the present disclosure is not limited thereto. Another type of lead screw such as triangular thread, trapezoidal thread, rectangular thread or serrated thread may also be used.

Optionally, as shown in FIG. 2, the first drive motor 21 is a servo motor, the first drive motor 21 is connected to a first mount 28, and the first mount 28 is fixed on the movable base 23, thereby facilitating the installation of the first drive motor 21.

Optionally, as shown in FIG. 2, the nut 25 is connected to a nut fixing base 29, and the nut fixing base 29 is connected to the chassis 10, thereby facilitating the installation of the nut 25 and improving the connection reliability between the nut 25 and the chassis 10.

Optionally, as shown in FIG. 2, the movable base 23 is provided with a connecting plate 231, and the deviation correction detection member 24 is disposed on the connecting plate 231.

In some embodiments, the translation deviation correction mechanism 20 includes a translation mechanism in which a gear (not shown) drives a rack (not shown) to linearly move. For example, the first drive motor 21 drives the gear to rotate, and the gear meshes with the rack to drive the rack to move. The slurry laying mechanism 30 is connected to the rack, which also achieves horizontal movement for deviation correction.

In some embodiments, as shown in FIG. 4, a guiding mechanism 60 is disposed between the movable base 23 and the chassis 10. The guiding mechanism 60 includes a slide rail 61 and a moving slider 62. The slide rail 61 is disposed on the chassis 10 in a width direction of the chassis 10. The moving slider 62 is fitted on the slide rail 61 and connected to the movable base 23. When the movable base 23 moves horizontally, with the slide rail 61 and the moving slider 62, stable translation of the movable base 23 on the chassis 10 can be ensured, thereby improving the movement reliability.

In some embodiments, as shown in FIG. 4, multiple moving sliders 62 are arranged at intervals on the slide rail 61. For example, two moving sliders 62 are provided.

In some embodiments, as shown in FIGS. 1 and 2, the fluid laying device 100 further includes an up-down leveling mechanism 50 disposed between the movable base 23 and the slurry laying mechanism 30 to adjust heights of two ends of the slurry laying mechanism 30 in a length direction of the slurry laying mechanism 30. The up-down leveling mechanism 50 includes a lifter 51 and a leveling detection member 53. The lifter 51 is disposed on the movable base 23, an output end of the lifter 51 is drivingly connected to the slurry laying mechanism 30, and the leveling detection member 53 is disposed on the movable base 23. When up-down leveling is performed, the lifter 51 ascends to increase a height of an end of the slurry laying mechanism 30 relative to the construction surface 300, and the lifter 51 descends to decrease the height of the end of the slurry laying mechanism 30 relative to the construction surface 300.

When the fluid laying device 100 works, the leveling detection member 53 controls the lifter 51 to ascend and descend according to the received laser rays so that a bottom of the slurry laying mechanism 30 is kept parallel to the construction surface. Specifically, the bottom of the slurry laying mechanism 30 refers to a bottom edge of the toothed scraper 32. That is to say, when the fluid laying device 100 works normally, a position of horizontal laser rays O2 emitted by the laser generator 200 and received by the leveling detection member 53 is a horizontal zero position; the up-down leveling mechanism 50 is configured to drive the slurry laying mechanism 30 to ascend and descend so that the position of the horizontal laser rays O2 received by the leveling detection member 53 can return to the horizontal zero position. In a process of laying tiles, when the slurry laying mechanism 30 works normally, the bottom of the slurry laying mechanism 30 is kept parallel to the construction surface 300. Due to the influence of the unevenness of a laying surface, the laid slurry surface is uneven. When the position of the horizontal laser rays O2 emitted by the laser generator 200 and received by the leveling detection member 53 is not at the horizontal zero point, the up-down leveling mechanism 50 is started to adjust the heights of the two ends of the slurry laying mechanism 30 so that the bottom of the slurry laying mechanism 30 is kept parallel to the construction surface 300, thereby ensuring that the laid slurry surface is even in height. The horizontal laser rays O2 emitted by the laser generator 200 is used as a horizontal plane elevation reference, and the leveling detection member 53 receives a signal of the horizontal plane elevation reference to control the up-down leveling mechanism 50, so as to solve the quality problem of the unevenness of the laid slur y surface caused by the unevenness of the construction surface 300. Optionally, the leveling detection member 53 may directly control the lifter 51 according to the received laser rays. Alternatively, a controller (not shown) is provided in the fluid laying device 100, the leveling detection member 53 converts the received laser rays into an electrical signal and transmits the electrical signal to the controller, and the controller controls the lifter 51 according to the electrical signal.

Optionally, the leveling detection member 53 is a photoelectric position sensitive sensor.

Optionally, as shown in FIG. 2, two up-down leveling mechanisms 50 are provided, and the two up-down leveling mechanisms 50 are correspondingly disposed at the two ends of the slurry laying mechanism 30 along the length direction of the slurry laying mechanism 30 to adjust the heights of the two ends of the slurry laying mechanism 30 respectively. That is to say, the two up-down leveling mechanisms 50 can independently adjust the heights of the two ends of the slurry laying mechanism 30. For example, as shown in FIGS. 7 and 8, when the construction surface 300 at a left end of the slurry laying mechanism 30 is relatively high, the up-down leveling mechanism 50 at the left end raises the slurry laying mechanism 30; and when the construction surface 300 at the left end of the slurry laying mechanism 30 is relatively low, the up-down leveling mechanism 50 at the left end lowers the slurry laying mechanism 30. As shown in FIGS. 9 and 10, when the construction surface 300 at a right end of the slurry laying mechanism 30 is relatively high, the up-down leveling mechanism 50 at the right end raises the slurry laying mechanism 30; and when the construction surface 300 at the right end of the slurry laying mechanism 30 is relatively low, the up-down leveling mechanism 50 at the right end lowers the slurry laying mechanism 30. It is to be understood that the two up-down leveling mechanisms 50 are correspondingly disposed at the two ends of the slurry laying mechanism 30 along the length direction of the slurry laying mechanism 30. The “two ends” here may refer to the utmost edge end of the slurry laying mechanism 30 along the length direction or may also refer to a region within a certain reasonable range near the utmost edge end of the slurry laying mechanism 30 along the length direction. The “two ends” in “the heights of the two ends of the slur laying mechanism 30” refers to the utmost edge end of the slurry laying mechanism 30 along the length direction.

In some embodiments, as shown in FIG. 2, the lifter 51 includes a third motor 511 and a linear electric cylinder 512, where the third motor 511 is connected to the linear electric cylinder 512 to drive the linear electric cylinder 512 to stretch out and draw back, and a telescopic rod of the linear electric cylinder 512 is connected to the slurry laying mechanism 30.

Optionally, the rotating member 52 is a steering gear, where an output end of the steering gear is drivingly connected to the leveling detection member 53, and the steering gear is used to conveniently and accurately control a rotation angle of the leveling detection member 53. Of course, the rotating member 52 may also be a stepper motor or a rotating cylinder, which is not repeated here.

In some embodiments, as shown in FIG. 2, the up-down leveling mechanism 50 further includes a linear guide rail 54, where the linear guide rail 54 is connected to the output end of the lifter 51, a slider of the linear guide rail 54 is connected to the movable base 23, and the linear guide rail 54 is connected to the slurry laying mechanism 30 through a pin shaft 55. That is to say, the linear guide rail 54 can play a guiding role, and the lifter 51 has better stability when driving the slurry laying mechanism 30 to ascend and descend.

In some embodiments, as shown in FIG. 2, an upper end of the linear guide rail 54 is drivingly connected to the output end of the lifter 51 through a connecting rod 56.

In some embodiments, as shown in FIG. 2, the slurry laying mechanism 30 includes a slurry box 31 and a toothed scraper 32. A slurry outlet (not shown) is provided below the slurry box 31. The toothed scraper 32 is disposed on the slurry outlet and extends in a length direction of the slurry box 31. That is to say, the slurry in the slurry box 31 reaches the toothed scraper 32 through the slurry outlet, and the slurry is scraped by the toothed scraper 32 into a straight toothed surface.

Optionally, as shown in FIG. 3, the slurry supply mechanism 40 includes a slurry hopper 41, a screw delivery rod 42, a delivery pipe 43, and a second drive motor 44. The slurry hopper 41 is disposed on the chassis 10. The screw delivery rod 42 is pivotally disposed in the slurry hopper 41. The delivery pipe 43 is disposed on the slurry hopper 41, where one end of the delivery pipe 43 is communicated with a delivery end of the screw delivery rod 42 and the other end of the delivery pipe 43 is communicated with the slurry box 31. An output end of the second drive motor 44 is drivingly connected to the screw delivery rod 42. It is to be understood that the screw delivery rod 42 is disposed at a bottom of the slurry hopper 41, the second drive motor 44 drives the screw delivery rod 42 to rotate, the slurry in the slurry hopper 41 is discharged to the delivery end along with the screw delivery rod 42, and then the slurry reaches the slurry box 31 through the delivery pipe 43, thereby achieving the feeding of the slurry laying mechanism 30.

As shown in FIGS. 7 and 9, when the ground is uneven, the chassis 10 is inclined. At this time, the slurry laying mechanism 30 follows the chassis 10 to tilt. The chassis 10 in FIG. 7 is inclined to the left, and the chassis 10 in FIG. 9 is inclined to the right. The leveling detection member 53 on the slurry laying mechanism 30 senses that the position of the horizontal laser rays O2 emitted by the laser generator 200 is away from the horizontal zero position, the leveling detection member 53 generates a signal, and the third motor 511 is controlled by a program to drive a piston rod of the linear electric cylinder 512 to move up and down, thereby driving the connecting rod 56, the linear guide rail 54, the rotating member 52, the leveling detection member 53, the pin shaft 55, and the slurry box 31 to move up and down together until the horizontal laser rays O2 emitted by the laser generator 200 returns to the horizontal zero position of the leveling detection member 53.

In addition, the fluid in the present disclosure is not limited to mortar, and may also be tile glue or the like.

A floor tile laying robot (not shown) in an embodiment of the present disclosure includes the preceding fluid laying device 100.

In the floor tile laying robot in the embodiment of the present disclosure, the fluid laying device 100 is used, the vertical laser rays O1 is used as the reference parallel to the floor tile edge line, and the deviation correction detection member 24 receives the signal of the laser rays parallel to the floor tile edge line to control the translation deviation correction mechanism 20 to perform deviation correction on the slurry laying mechanism 3 in the horizontal direction 0. In this manner, it can be ensured that a laid slurry surface is linearly laid, and manual work can be replaced to complete laying of an adhesive fluid, thereby avoiding a quality problem caused by nonstandard manual operation, reducing the labor intensity of workers, and improving the slurry laying efficiency.

A slurry hiving method in an embodiment of the present disclosure includes the preceding fluid laying device 100.

As shown in FIGS. 6 to 13, the slurry laying method includes the steps described below.

In step S1, the chassis 10 moves along a slurry laying direction, the slurry supply mechanism 40 delivers the fluid to the slurry laying mechanism 30, and the slurry laying mechanism 30 lays the slurry on the construction surface 300. That is to say, when the fluid laying device 100 works normally, the construction surface 300 is horizontal, the chassis 10 and the slurry laying mechanism 30 are in a horizontal state, the chassis 10 is not offset, the slurry laying mechanism 30 and the chassis 10 are in an aligned state, the position of the vertical laser rays O1 emitted by the laser generator 200 and received by the deviation correction detection member 24 is at the vertical zero position, and the fluid laying device 100 performs slurry laying linearly.

In step S2, the deviation correction detection member 23 controls the translation deviation correction mechanism 20 according to the received laser rays to adjust a horizontal position of the slurry laying mechanism 30 so as to perform slurry laying linearly along the laying direction.

Specifically, when the position of the vertical laser rays O1 received by the deviation correction detection member 24 is not at the vertical zero position, the movable base 23 drives the slurry laying mechanism 30 to move until the position of the vertical laser rays O1 received by the deviation correction detection member 24 returns to the vertical zero position.

That is to say, when the chassis 10 is offset, the slurry laying mechanism 30 and the chassis 10 are not in the aligned state. At this time, the position of the vertical laser rays O1 received by the deviation correction detection member 24 is not at the vertical zero position, the translation deviation correction mechanism 20 is started, and the movable base 23 drives the slurry laying mechanism 30 to move for deviation correction until the position of the vertical laser rays O1 received by the deviation correction detection member 24 returns to the vertical zero position.

Optionally, the deviation correction detection member 24 may directly control the translation deviation correction mechanism 20 according to the received laser rays. Alternatively, a controller (not shown) is provided in the fluid laying device 100, the deviation correction detection member 24 converts the received laser rays into an electrical signal and transmits the electrical signal to the controller, and the controller controls the translation deviation correction mechanism 20 according to the electrical signal.

According to the slurry laying method of the embodiment of the present disclosure, taking the vertical laser rays O1 as the reference parallel to the floor tile edge line, the deviation correction detection member 24 receives the signal of the laser rays parallel to the floor tile edge line to control the translation deviation correction mechanism 20 to perform deviation correction on the slurry laying mechanism 30 in the horizontal direction. Due to ground flatness, sundries (such as gravel) and other reasons, the existing slurry laying robot cannot move in a straight line, and slurry laying cannot be performed linearly. In the present disclosure, it can be ensured that a laid slurry surface is linearly laid, and manual work can be replaced to complete laying of an adhesive fluid, thereby avoiding a quality problem caused by nonstandard manual operation, reducing the labor intensity of workers and improving the slurry laying efficiency.

In some embodiments, the fluid laying device 100 further includes the up-down leveling mechanism 50 that is disposed between the movable base 23 and the slurry laying mechanism 30 and includes the leveling detection member 53.

The slurry laying method further includes the step described below.

In step S3, the leveling detection member 53 controls the up-down leveling mechanism 50 according to the laser rays to adjust a height of the slurry laying mechanism 30 to keep the bottom of the slurry laying mechanism 30 parallel to the construction surface. Specifically, the bottom of the slurry laying mechanism 30 refers to the bottom edge of the toothed scraper 32.

Specifically, when the fluid laying device 100 works normally, the position of the horizontal laser rays O2 emitted by the laser generator 200 and received by the leveling detection member 53 is at the horizontal zero position. When the fluid laying device 100 works and the position of the horizontal laser rays O2 received by the leveling detection member 53 is not at the horizontal zero position, the up-down leveling mechanism 50 drives at least one end of the slurry laying mechanism 30 to ascend and descend until the position of the horizontal laser rays O2 received by the leveling detection member 53 returns to the horizontal zero position.

That is to say, when the construction surface 300 is not horizontal, the chassis 10 and the slurry laying mechanism 30 are not in a horizontal state. At this time, the position of the horizontal laser rays O2 received by the leveling detection member 53 is not at the horizontal zero position, and the up-down leveling mechanism 50 is started to drive the left end or right end of the slurry laying mechanism 30 to ascend and descend until the position of the horizontal laser rays O2 received by the leveling detection member 53 returns to the horizontal zero position.

Optionally, the leveling detection member 53 may directly control the up-down leveling mechanism 50 according to the received laser rays. Alternatively, a controller (not shown) is provided in the fluid laying device 100, the leveling detection member 53 converts the received laser rays into an electrical signal and transmits the electrical signal to the controller, and the controller controls the up-down leveling mechanism 50 according to the electrical signal.
