Abstract
Description
Technical Field
[0001] This invention belongs to the field of interior decoration technology, specifically an interior wall tile laying machine. Background Technology
[0002] Current wall tile laying machines integrate multiple functional modules, mainly including a material storage system, a tile-picking robot, an adsorption and positioning unit, and a mortar coating device. The adsorption and positioning unit, as a key functional component, is responsible for gripping, moving, and precisely positioning the tiles, and generally adopts a vacuum suction cup structure based on the principle of negative pressure adsorption.
[0003] Under ideal working conditions, the vacuum suction cup should maintain full contact with the smooth surface of the tile to form an effective sealed cavity, thereby generating the required adsorption force and achieving reliable adsorption and fixation of the tile. However, in actual installation, the tile surface often has residual release agent, dust, or contaminants such as hard debris adhering to it during storage, transportation, and loading. These impurities, especially solid particles, will disrupt the seal between the suction cup and the tile surface, leading to localized air leakage. External air seeps into the adsorption cavity under pressure difference, causing the vacuum level to fail to reach the rated threshold. As a result, the adsorption force is significantly weakened or even completely lost, ultimately causing the tile to fall off or break during transportation, resulting in tile waste and low construction efficiency.

A fixing rod is fixedly connected to the support frame, and the remaining two diagonally distributed positioning blocks are slidably connected to the fixing rod. Adjacent positioning blocks are hinged together by a connecting rod.
[0008] Furthermore, the control component includes a support rod fixedly connected to an adjacent mounting base. The support rod is splined to a pressure-bearing component. A first elastic element is provided between the pressure-bearing component and the adjacent mounting base. An adjusting cylinder is rotatably connected within the mounting base, and a second elastic element is provided between the two. The mounting base is provided with an exhaust channel. The adjusting cylinder is used to control the communication state between the adjacent second pipe, the exhaust channel, and the suction cup. A trigger block is fixedly connected to the side of the elastic membrane near the pressure-bearing component. The trigger block is used to push the pressure-bearing component to move.
[0009] Furthermore, a pressing rod is fixedly connected to the pressure-bearing component, and a limiting groove is provided inside the adjusting cylinder to limit the pressing rod.
[0010] Furthermore, it also includes four buffer mechanisms, all disposed within the transition block, each used to control the flow rate of gas within the transition channel.

Symmetrically distributed baffles are fixed within the mounting base. The baffles are made of elastic material, and the telescopic ends of the electric push rods are hinged to adjacent baffles. The symmetrically distributed baffles are used to control the flow rate of gas within the transition channel.
[0011] Furthermore, it also includes a connecting mechanism disposed on the mounting frame for supporting the support frame and causing the support frame to deflect. The connecting mechanism includes symmetrically distributed fixed shells, which are fixedly connected to the mounting frame. A lifting plate is slidably connected to the fixed shell and is slidably connected to the support frame.

[0015] The beneficial effects of the present invention using the above structure are as follows: The present invention promotes the rapid flow of air between the elastic membrane and the tile through the reciprocating deformation of the elastic membrane, thereby allowing the flowing gas to carry away impurities between the elastic membrane and the tile, ensuring the cleanliness of the tile surface, ensuring that the tile is firmly fixed, thereby reducing the probability of the tile falling off and reducing tile waste.
[0016] This invention can adjust the swing amplitude of the baffle plate according to the state of the adhesive and the environmental conditions during the installation process, control the flow of gas in the transition channel, thereby changing the amount of gas entering the adjacent second tube. This adjusts the speed of suction cup depressurization, allowing the suction cup to achieve a slow depressurization effect, prolonging the time the suction cup is fixed to the tile, ensuring that the tile is firmly fixed to the wall, and reducing the probability of the tile falling off.
[0017] This invention uses a support plate that is attached to the wall and the support frame is adjusted to an inclined state to catch tiles falling from the wall, preventing the tiles from falling directly to the ground and causing damage, thus achieving the purpose of preventing tiles from falling.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Example 1
[0022] Research has found that when using suction cups to fix tiles, hard particulate impurities adhere to the surface of the tiles. During the process of suction cup adsorption of the tiles, these impurities can disrupt the seal between the suction cup and the tile surface, leading to localized air leakage. As a result, the vacuum level cannot reach the rated threshold, and the adsorption force is significantly reduced or even completely lost.
[0023] An indoor wall tile laying machine, such as Figures 1-5As shown, the system includes a mobile platform 1, which consists of an existing omnidirectional mobile vehicle and a lifting module, and is used to adapt to construction sites of different environments and heights. A mounting frame 2 is fixedly connected to the mobile platform 1, and a support frame 3 is provided on the mounting frame 2. In this embodiment, the mounting frame 2 and the support frame 3 are fixedly connected. A fixing plate 4 is fixedly connected to the support frame 3, and four positioning blocks 5 are slidably connected to the fixing plate 4. The four positioning blocks 5 are arranged in a rectangular shape. A mounting base 6 is fixedly connected to the positioning blocks 5, and a suction cup 7 is fixedly connected to the mounting base 6. The suction cup 7 is an existing structure, and an elastic membrane 8 is fixedly connected to the suction cup 7. The elastic membrane 8 is used to protect the suction cup 7 and prevent the suction cup 7 from contacting the tile, thereby avoiding wear caused by impurities on the tile. A sealed cavity is formed between the suction cup 7 and the elastic membrane 8. A pneumatic mechanism for evacuating all suction cups 7 is provided on the support frame 3, and an adjustment mechanism for driving all positioning blocks 5 to slide is provided on the support frame 3.
[0024] like Figures 2-6 As shown, the pneumatic mechanism includes an air supply pump 9, which is an existing air pump. The air supply pump 9 is installed on the left side of the support frame 3. A transition block 10 is fixedly connected to the left side of the support frame 3. The air inlet of the air supply pump 9 is connected to a first pipe 11. Four second pipes 12 are fixedly connected to the right side of the transition block 10. A transition channel 13 is provided inside the transition block 10. The first pipe 11 and all the second pipes 12 are connected to the transition channel 13. The transition channel 13 is used to divert the gas in the first pipe 11 to the four second pipes 12. A control component is provided on the mounting base 6 to control the connection between the second pipes 12 and the adjacent suction cups 7.
[0025] like Figures 2-4 As shown, the adjustment mechanism includes a drive motor 14, which is fixedly connected to the support frame 3. The output shaft of the drive motor 14 is fixedly connected to a drive rod 15, which has symmetrically distributed threads. The two threads on the drive rod 15 are respectively threaded to two of the diagonally distributed positioning blocks 5. The drive rod 15 is used to control the corresponding two positioning blocks 5 to move in opposite directions (backwards). A fixing rod 16 is fixedly connected to the support frame 3. The other two diagonally distributed positioning blocks 5 are slidably connected to the fixing rod 16. Adjacent positioning blocks 5 are hinged together with connecting rods 17. All connecting rods 17 are used to make all positioning blocks 5 move synchronously. When the drive rod 15 drives the two positioning blocks 5 on it to move in opposite directions, the other two positioning blocks 5 move backwards under the action of the adjacent connecting rods 17. When the drive rod 15 drives the two positioning blocks 5 on it to move backwards, the other two positioning blocks 5 move in opposite directions under the action of the adjacent connecting rods 17. Through the relative movement of all positioning blocks 5, the position of the suction cup 7 is changed, so that the suction cup 7 can adapt to tiles of different sizes.
[0026] like Figure 5 and Figures 7-10As shown, the control assembly includes a support rod 21, which is fixedly connected to an adjacent mounting base 6. A pressure-bearing component 22 is splined to the support rod 21. The pressure-bearing component 22 consists of a circular plate, a cylinder, and a circular rod, with a gap between the rod and the cylinder. The support rod 21 slides within this gap. A first elastic element 221, a spring, is provided between the pressure-bearing component 22 and the adjacent mounting base 6 to reset the pressure-bearing component 22. An adjusting cylinder 23 is rotatably connected within the mounting base 6, and a second elastic element 231, a torsion spring, is provided between the two, initially in a charged state. The adjusting cylinder 23 is equipped with… The flow hole has a first elastic element 221 with a greater elastic coefficient than the second elastic element 231. The mounting base 6 is provided with an exhaust channel 27. The adjusting cylinder 23 is used to control the communication state between the adjacent second pipe 12 and the exhaust channel 27 and the suction cup 7. When the flow hole is aligned with the adjacent second pipe 12, the second pipe 12 is connected to the suction cup 7, which is the initial state. When the flow hole is connected to the adjacent exhaust channel 27, the suction cup 7 is connected to the outside. A trigger block 24 is fixed to the left side of the elastic membrane 8. The trigger block 24 is a hemisphere. This shape is only for illustration and any shape is acceptable. The trigger block 24 is used to push the pressure member 22 to move.
[0027] like Figure 9 and Figure 10 As shown, a pressing rod 25 is fixedly connected to the pressure-bearing component 22. The pressing rod 25 is an elastic telescopic rod. A limiting groove 26 is provided inside the adjusting cylinder 23. The limiting groove 26 is composed of an arc-shaped groove, an inclined groove, and a straight groove connected in sequence. A slope is provided at the connection between the inclined groove and the straight groove. The limiting groove 26 is used to limit the pressing rod 25. The pressing rod 25 is initially located on the right side of the straight groove on the limiting groove 26.
[0028] The working principle of this embodiment: When using this device to lay tiles, first move the entire device to the tile laying position using the moving platform 1. Then, adjust the position of all positioning blocks 5 according to the size of the tiles. The specific adjustment process is as follows: turn on the drive motor 14. The output shaft of the drive motor 14 drives the drive rod 15 to rotate. The drive rod 15 drives the two positioning blocks 5 on it to move. These two positioning blocks drive the other two positioning blocks 5 to move through the connecting rod 17 on them. When the two positioning blocks 5 on the drive rod 15 move to correspond to the size of the tiles, turn off the drive motor 14. This completes the adjustment of all positioning blocks 5.
[0029] After adjusting all the positioning blocks 5 to the appropriate positions, the smooth surface of the tile is attached to all the elastic membranes 8. Then, the air supply pump 9 is turned on and starts to work, extracting the air from all the suction cups 7. At this time, the air enters the transition channel 13 through the second pipe 12, then passes through the first pipe 11 and is discharged by the air supply pump 9. During this process, the air in all the suction cups 7 gradually decreases, that is, the pressure in the sealed cavity of the suction cups 7 decreases. Under the action of negative pressure, all the elastic membranes 8 gradually indent inward (gradually accumulating force), and the elastic membranes 8 drive the adjacent trigger blocks 24 to move.
[0030] During the process of the elastic membrane 8 being recessed, if there are no impurities on the tile, the elastic membrane 8 and the tile are in a sealed and fitted state. At this time, a negative pressure will be formed between the elastic membrane 8 and the tile. This pressure will gradually fix the tile. Taking one of the elastic membranes 8 as an example, when the tile is fixed, the air supply pump 9 is turned off. At this time, the elastic membrane 8 has not deformed to the limit state, that is, the trigger block 24 has not contacted the adjacent pressure-bearing component 22.
[0031] If impurities are present on the tile, the elastic membrane 8 and the tile are not in a sealed fit. During the process of the elastic membrane 8 indenting inward, outside air will enter between the elastic membrane 8 and the tile through the gap. At this time, the tile is not completely fixed, and the air pump 9 continues to work, that is, the pressure in the suction cup 7 will continue to decrease, and the elastic membrane 8 will continue to indent inward (the deformation at this time is greater than the deformation when there are no impurities). The elastic membrane 8 drives the trigger block 24 to continue to move until the trigger block 24 contacts the pressure member 22. The trigger block 24 then squeezes the pressure member 22, causing the pressure member 22 to move to the left. The pressure member 22 drives the extrusion rod 25 to move. The extrusion rod 25 slides along the straight groove of the limiting groove 26, and the pressure member 22 squeezes the adjacent first elastic member 221.
[0032] When the extrusion rod 25 moves to the junction of the arc groove and the straight groove on the limiting groove 26, the adjusting cylinder 23 starts to rotate under the action of the second elastic element 231. The extrusion rod 25 begins to slide along the arc groove of the limiting groove 26. The adjusting cylinder 23 blocks the adjacent second pipe 12 and connects its flow hole with the adjacent exhaust channel 27. At this time, the sealed cavity in the suction cup 7 is connected to the outside through the exhaust channel 27. The suction cup 7 loses connection with the air supply pump 9. Afterward, the elastic membrane 8 resets outward under its own elasticity and quickly returns to its initial state. During this process, outside air quickly enters the sealed cavity in the suction cup 7 through the exhaust channel 27, that is, the suction cup 7 returns to the normal pressure state until the extrusion rod 25 moves to the junction of the inclined groove and the arc groove on the limiting groove 26. At this time, the adjusting cylinder 23 stops rotating. The flow hole of the adjusting cylinder 23 is aligned with the exhaust channel 27.
[0033] During the reset process of the elastic membrane 8, the right side of the elastic membrane 8 quickly pushes the air between it and the tile, causing the air to be quickly discharged along the gap between the elastic membrane 8 and the tile. As the air is discharged, it impacts the impurities in the gap, blowing them out. As the elastic membrane 8 resets, it drives the trigger block 24 to reset and move, causing the trigger block 24 to lose its pressure on the pressure member 22.
[0034] After the elastic membrane 8 is reset, when the extrusion rod 25 moves into the inclined groove of the limiting groove 26, the pressure member 22 moves to the right under the action of the first elastic member 221 and the pressure member 22 drives the extrusion rod 25 to move synchronously. The extrusion rod 25 slides along the inclined groove of the limiting groove 26. During this process, the extrusion rod 25 extrudes the limiting groove 26, causing the adjusting cylinder 23 to rotate in the opposite direction. The adjusting cylinder 23 twists the second elastic member and causes it to start accumulating force. During this process, the flow hole of the adjusting cylinder 23 gradually loses communication with the exhaust channel 27 and gradually connects with the adjacent second pipe 12 until the extrusion rod 25 contacts the slope on the limiting groove 26 and the extrusion rod 25 is compressed. After the pressure member 22 is reset, the extrusion rod 25 loses contact with the slope of the limiting groove 26 and re-enters the straight groove of the limiting groove 26 (initial position).
[0035] After the pressure-bearing component 22 has been reset, the elastic membrane 8 has also been reset, and the single cleaning operation has been completed. Then, the air supply pump 9 is started, and the above-mentioned vacuuming operation on the suction cup 7 is repeated.
[0036] After the air pump 9 is started for the second time, if the impurities between the elastic membrane 8 and the tile are cleaned, the elastic membrane 8 and the tile will be sealed together, and the air extraction operation will be repeated until the tile is fixed. If the impurities between the elastic membrane 8 and the tile are not cleaned, the operation of the elastic membrane 8 continuing to sink and using the reset of the elastic membrane 8 to impact the impurities will be repeated to clean them again. This operation can be repeated multiple times until the impurities are cleaned and the tile is firmly fixed.
[0037] After the tiles are fixed, the moving platform 1 is controlled to lay the tiles in the target position. After the tiles are laid, the air supply pump 9 is controlled to bring all the suction cups 7 to a normal pressure state, that is, to lose the adhesion to the tiles. Then, all the above operations are repeated to continue laying the next tile.
[0038] Example 2
[0039] Research has found that when using suction cups to lay tiles, if the suction cup is immediately depressurized and removed after the tiles are laid, the adhesive (tile glue / cement mortar) under the tiles is still in a fluid or partially set state and cannot provide any support. This can easily cause the tiles to sink or shift, seriously affecting the construction quality.
[0040] Based on Example 1, such as Figure 6 As shown, it also includes four buffer mechanisms, all located within the transition block 10, used to control the flow rate of gas within the transition channel 13. Each buffer mechanism corresponds to a second pipe 12. Each buffer mechanism includes two symmetrically distributed electric actuators 31. The electric actuators 31 are existing miniature electric actuators, with multi-level adjustable extension at their telescopic ends. The electric actuators 31 are fixed to the mounting base 6 and located within the transition channel 13. Two symmetrically distributed baffles 32 are fixed within the mounting base 6. The baffles 32 are made of elastic material and can be bent and deformed. The telescopic ends of the electric actuators 31 are hinged to adjacent baffles 32. The symmetrically distributed baffles 32 are used to control the flow rate of gas within the transition channel 13, i.e., to control the amount of gas entering the transition channel. After the tiles are laid, the negative pressure in the suction cup 7 needs to be released. At this time, all the electric push rods 31 are activated, and the telescopic ends of the electric push rods 31 extend and stretch the baffles 32, increasing the surface area of the two baffles 32 and blocking the passage of the transition channel 13. This reduces the flow area of the passage in the transition channel 13, thereby reducing the amount of gas flowing from the transition channel 13 to the second tube 12. This causes the suction cup 7 to slowly depressurize and slowly release the vacuum state of the suction cup 7, thereby extending the fixing time of the suction cup 7 on the tiles and ensuring that the adhesive has initially fixed the tiles, thus ensuring the stability of the tile bonding position. After the suction cup 7 has finished depressurizing, the telescopic ends of the electric push rods 31 are retracted, and all the baffles 32 return to their initial state.
[0041] During the extension process of the telescopic end of the electric push rod 31, the amount of extension of the telescopic end of the electric push rod 31 is determined according to the type of adhesive, ambient temperature and humidity. When the adhesive is not easy to cure, the extension amount of the telescopic end of the electric push rod 31 is larger, and vice versa.
[0042] Example 3
[0043] Based on Example 2, such as Figures 1-3 and Figures 11-13As shown, it also includes a connecting mechanism, which is set on the mounting frame 2, for supporting the support frame 3 and causing the support frame 3 to deflect. The connecting mechanism includes two fixed shells 41 symmetrically distributed front and back. The fixed shells 41 are fixed to the right side of the mounting frame 2. A lifting plate 42 is slidably connected to the fixed shells 41. The lifting plate 42 is used to support the support frame 3 and to support the bottom of the tile, preventing the tile from falling directly and breaking. The lifting plate 42 is slidably connected to the support frame 3. Two support push rods 43 are hinged on the mounting frame 2, which are symmetrically distributed front and back. The telescopic ends of the support push rods 43 are hinged to the upper part of the support frame 3. By retracting the telescopic ends of the support push rods 43, the upper part of the support frame 3 is deflected, so that the support frame 3 is in an inclined state, thereby catching the falling tile. All the suction cups 7 are used to fix the tile, further preventing the tile from falling and breaking, and ensuring the integrity of the tile.
[0044] like Figures 1-3 and Figure 11 As shown, an oil reservoir 51 and a compression push rod 52 are fixedly connected to the mounting bracket 2. The oil reservoir 51 stores hydraulic oil. A piston plate 53 is fixedly connected to the telescopic end of the compression push rod 52. The compression push rod 52 is an existing telescopic rod with active force, and its driving method can be electric, hydraulic or pneumatic. The piston plate 53 is located in the middle of the oil reservoir 51. Hydraulic oil is present on both the upper and lower sides of the piston plate 53. The piston plate 53 and the oil reservoir 51 are connected in a sealed sliding connection. The fixed part of the support push rod 43 is connected to the upper part of the oil reservoir 51 through a hose, that is, the connection position between the two is located above the piston plate 53.
[0045] like Figures 11-13 As shown, a fixed sleeve 61 is fixedly connected inside the fixed shell 41. The fixed sleeve 61 is connected to the lower part of the oil storage shell 51 through a hose. That is, the connection between the two is located below the piston plate 53. The connection between the fixed sleeve 61 and the oil storage shell 51 and the connection between the fixed part of the support push rod 43 and the oil storage shell 51 are respectively located on both sides of the piston plate 53. A piston component 62 is slidably connected inside the fixed sleeve 61. The piston component 62 is composed of a round plate and a round rod. The round rod of the piston component 62 is fixedly connected to the adjacent lifting plate 42. By moving the piston component 62, the adjacent lifting plate 42 is moved, so that the right side of the lifting plate 42 is in contact with the wall and catches the falling tiles.
[0046] like Figures 11-13 As shown, a rack 71 is fixedly connected to the upper side of the lifting plate 42, and two symmetrically distributed gears 72 are fixedly connected to the lower side of the support frame 3. The rack 71 meshes with the adjacent gears 72.
[0047] The working principle of this embodiment: After the tiles are laid, the extrusion push rod 52 is activated. The telescopic end of the extrusion push rod 52 extends and drives the piston plate 53 to move downward. The piston plate 53 extrudes the hydraulic oil in the lower part of the oil reservoir 51. This hydraulic oil enters the two fixed sleeves 61 through the hose. Taking one of the fixed sleeves 61 as an example, the oil pressure in the fixed sleeve 61 increases, and the hydraulic oil extrudes the piston 62, causing the piston 62 to move to the right. The piston 62 pushes the adjacent support plate 42 to move to the right until the support plate 42 is in contact with the wall.
[0048] As the piston plate 53 moves downward, a negative pressure is formed at the top of the oil reservoir 51, and hydraulic oil is drawn from the fixed parts of the two support push rods 43 through the hose, causing the telescopic ends of the two support push rods 43 to retract. The telescopic ends of the support push rods 43 drive the upper side of the support frame 3 to move to the left, causing the support frame 3 to gradually tilt. At this time, if the tile falls off, the support frame 3 and its upper parts will catch the falling tile, so that the side of the tile will contact all the suction cups 7 again, thus preventing the tile from falling directly to the ground and being damaged.
[0049] During the movement of the lifting plate 42, the lifting plate 42 drives the rack 71 on it to move synchronously. The rack 71 drives the adjacent gear 72 to move to the right. The two gears 72 together drive the lower side of the support frame 3 to move to the right. During this process, as the support frame 3 tilts, the support frame 3 drives the two gears 72 to rotate, causing the two gears 72 to move to the left relative to the adjacent rack 71. This causes the lower side of the support frame 3 to move to the left relative to the lifting plate 42, increasing the distance between the lower side of the support frame 3 and the right side of the lifting plate 42 and forming a gap. At this time, if the laid tiles are not firmly fixed and detach from the wall, the two lifting plates 42 and the gap between the right side of the lifting plate 42 and the lower side of the support frame 3 are used to catch the lower side of the falling tiles, preventing the falling tiles from falling directly to the ground and causing damage.
[0050] After the lifting plate 42 is in contact with the wall, the moving platform 1 is controlled to move its components away from the wall. During this process, the telescopic end of the compression push rod 52 slowly extends and continues to drive the piston plate 53 downward. That is, the hydraulic oil in the lower part of the oil reservoir 51 continues to flow into the two fixed sleeves 61. The purpose is to keep the two lifting plates 42 in contact with the wall and maintain the state of receiving falling tiles as the moving platform 1 moves away. At the same time, as the piston plate 53 moves downward, the upper part of the oil reservoir 51 is still in a negative pressure state and continues to draw out the oil from the fixed parts of the two support push rods 43. Hydraulic oil causes the telescopic end of the support push rod 43 to continue to retract, that is, the tilt angle of the support frame 3 gradually increases. The angle at which the support frame 3 drives the gear 72 to rotate gradually increases, thereby increasing the rotation angle of the gear 72 relative to the rack 71. This, in turn, increases the gap between the right side of the lifting plate 42 and the lower side of the support frame 3, making it easier to catch falling tiles. By keeping the two lifting plates 42 in contact with the wall during the initial movement of the moving platform 1 away from the wall, the protection time for the tiles is extended, ensuring that the tiles are firmly fixed to the wall and reducing the probability of tile damage.
[0051] When the lifting plate 42 moves to its limit position, i.e., when the piston 62 can no longer move, the moving platform 1 continues to move and drives all its parts to move synchronously. At this time, the two lifting plates 42 lose contact with the wall. Then, the extension end of the control compression push rod 52 retracts and drives the piston plate 53 to move upward. The piston plate 53 compresses the hydraulic oil in the upper part of the oil reservoir 51, so that this part of the hydraulic oil gradually enters the fixed part of the two support push rods 43 through the hose. During this process, the extension end of the support push rod 43 extends and pushes the support frame 3. At the same time, as the piston plate 53 moves upward, the hydraulic oil in the two fixed sleeves 61 flows back into the oil reservoir 51. The two pistons 62 begin to move to the left and drive the adjacent lifting plates 42 to move synchronously. The lifting plate 42 drives the lower side of the support frame 3 to move to the left through the rack 71 and two gears 72 until the piston plate 53 is reset. The two lifting plates 42 are reset, and the support frame 3 returns to the vertical state. Then the compression push rod 52 is closed.
