Description

Technical Field

[0001] The present invention relates to the technical field of plate splicing, and in particular to a high-precision automatic splicing device and method for ALC plates based on a positioning guide rail. Background Art

[0002] ALC board is a kind of autoclaved lightweight concrete board made of cement, lime, silica sand and other raw materials through autoclaving process. It has many excellent properties such as light weight, high strength, heat preservation, heat insulation, sound insulation, fire prevention, etc. It is widely used in residential, commercial and industrial buildings, etc. It can be used as exterior wall panels, interior wall panels, floor panels, roof panels, etc.

[0003] During the board splicing process, special installation equipment is usually used to transfer the ALC boards to the designated location and adjust the verticality and flatness of the boards to ensure that the boards are firmly installed.

[0004] During the installation of ALC panels, the center point of the panel is usually adsorbed by a suction cup, and the panel is installed on the corresponding wall. During the installation, pressure needs to be applied to the panel through the suction cup, and the applied pressure radiates from the center of the panel to the corners. If the corners of the panel are to achieve the required installation pressure, the pressure applied by the suction cup needs to be increased, which will undoubtedly cause stress concentration in the panel, resulting in deformation or breakage of the panel. In order to solve the above problem, the panel can be provided with extrusion pressure all around. When the panel is installed at a corner of a wall, a load-bearing wall or other special position, the specifications of the panel will be changed accordingly to ensure the installation requirements, and the corresponding pressure points need to be adjusted. However, regardless of whether hydraulic, pneumatic or servo is used for adjustment, the panel size needs to be measured, and the corresponding data needs to be re-entered to adjust the required displacement, which complicates the installation of the panel.

[0015] A high-precision automatic splicing method of ALC plates based on positioning guide rails includes the following steps: Step 1: Place the required plate on the lifting plate, and position the plate under the action of the positioning clamping assembly; Step 2: Under the action of the adsorption flipping component, the suction cup, the splicing and pressing component, and the extrusion rod are controlled to move toward the plate; Step 3: When the suction cup and the extrusion rod are in contact with the plate, the adsorption flip assembly will adjust the position of the extrusion rod through the lifting and unfolding mechanism, and lock the position of the extrusion rod under the action of the yielding control mechanism; Step 4: The adsorption flip component controls the suction cup to lift to a certain height and then flip it to a position parallel to the wall, and pushes the suction cup and the squeezing rod toward the wall to perform a pressing action on the plate through the squeezing rod.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the present application can achieve the effect of providing uniform pressure at multiple points on the plates when assembling the plates by adaptively adjusting the spacing of the extrusion rods. Specifically, when the plates are placed on the lifting plate, the plates are centrally positioned under the action of the positioning and clamping assembly. At the same time, under the action of the adsorption and flipping assembly, the suction cup, the splicing and clamping assembly, and the extrusion rod are controlled to move toward the plate. When the suction cup, the extrusion rod, and the plate are in contact with the plate, under the action of the lifting and unfolding mechanism and the yielding and regulating mechanism, the position of the extrusion rod is adaptively adjusted, and when the extrusion rod moves to the desired pressure position, the position of the extrusion rod is locked. At this time, the adsorption and flipping assembly is lifted to a certain height by the suction cup, and after flipping to a position parallel to the wall, the plate is driven to move toward the wall until the plate is in contact with the wall. Under the action of the extrusion rod, the plate is provided with a uniform extrusion force at multiple points.

[0017] By centering the plate before adsorbing it, the plate will not shift during the adsorption of the plate by the suction cup and the assembly process. At the same time, the positions of the four extrusion rods can be adaptively adjusted before the plate is adsorbed, and the positions of the extrusion rods can be locked after the extrusion rods move to the desired positions, thereby achieving the effect of adaptive adaptation to assist in the installation of plates of different specifications. Among them, if the pressure points of the extrusion rods are adjusted by pneumatic, hydraulic, or servo, it is necessary to measure the size of the plate and input the corresponding data based on the measurement results before adjusting the displacement of the extrusion rods. The present application can adaptively adjust the pressure points of the extrusion rods according to the size of the plate during the adsorption of the plate by the suction cup, thereby achieving the effect of efficient and rapid installation of the plate.

[0018] The extrusion rod provides multi-point uniform pressure on the four sides of the plate, which can not only ensure that the plate will not cause the corners to warp due to uneven force, but also ensure that the plate will not cause the problem of breaking due to excessive force.

[0024] Specifically, when the plates are to be spliced, the translation guide rail 1 can be controlled to be lifted to the required height, and the plates can be placed on the lifting plate 5. At this time, under the action of the positioning and clamping assembly, the plates are positioned. At the same time, under the action of the adsorption and flipping assembly, the suction cup 17, the splicing and pressing assembly, the extrusion rod 15, and the limiting column 16 are controlled to move toward the plate. When the suction cup 17 and the extrusion rod 15 are both in contact with the plates, the adsorption and flipping assembly continues to move, and the movement of the splicing and pressing assembly is controlled by the lifting and unfolding mechanism to adjust the spacing between the extrusion rods 15. When the limiting column 16 moves to the position of conflicting cooperation with the positioning and clamping assembly, the position of the extrusion rod 15 no longer changes. Under the action of the yielding and regulating mechanism, the position of the extrusion rod 15 is locked. At this time, the plates can be adsorbed by the suction cup 17. After the adsorption is completed, the adsorption and flipping assembly is turned on. The plate is lifted to a certain height by the suction cup 17, and after the plate is driven to flip to a position parallel to the wall panel by the suction cup 17, the plate is controlled to fit the wall surface. Under the action of the extrusion rod 15, the plate is pressed on all sides to ensure that the plate is evenly stressed. When the plate is installed, the sliding plate 4 is controlled to move to the required assembly position of the next plate by the one-way screw rod 2 and the guide column 3 to install the next plate. By positioning the plate in advance, it is ensured that the plate will not shift during the plate grabbing process. At the same time, during the plate adsorption process, the extrusion rod 15 is synchronously adjusted to the edge position around the plate, so that during the assembly process of the plate on the wall, the extrusion rod 15 provides multi-point uniform pressure on the four sides of the plate, which can not only ensure that the plate will not cause the corners to curl up due to uneven stress, but also ensure that the plate will not cause the problem of breaking due to excessive stress.

[0025] See also Figure 1-Figure 3 The positioning and clamping assembly includes two groups of first slide grooves 501 that are opened on the lifting plate 5 and are cross-arranged, and two positioning plates 6 slide symmetrically in one group of the first slide grooves 501; it also includes two driving members for driving the two positioning plates 6 in one group of the first slide grooves 501 to move, and the two driving members include two cross-arranged bidirectional screw rods 7 that are rotatably installed on the lifting plate 5, and the bidirectional screw rods 7 are threadedly connected with symmetrically arranged threaded sleeves 8, and the threaded sleeves 8 are fixedly connected to the positioning plates 6.

[0026] Among them, when the plate needs to be assembled, in order to ensure that the plate will not be offset during assembly, the plate needs to be centrally positioned. In the initial state, under the action of the two bidirectional screw rods 7, the spacing between the four threaded sleeves 8 is maximized, so that the spacing between the positioning plates 6 is maximized. At this time, the plate can be placed on the lifting plate 5, and the two bidirectional screw rods 7 rotate and drive the four threaded sleeves 8 to move in a direction close to each other, thereby driving the positioning plates 6 to move. When two of the positioning plates 6 move to abut against the narrower side of the plate, one of the bidirectional screw rods 7 stops rotating, and the other bidirectional screw rod 7 continues to rotate until the other two positioning plates 6 abut against the longer side of the plate. Under the action of the four positioning plates 6, the plate is centrally positioned.

[0027] See also Figure 1-Figure 3 , Figure 5-Figure 9 The adsorption flip assembly includes a rotating rod 10 rotatably mounted on the fixed plate 9, a rotating plate 1001 is fixed on the rotating rod 10, a second cylinder 37 is fixed on the rotating plate 1001, a connecting plate 11 is fixed on the telescopic end of the second cylinder 37, a first cylinder 19 and a support rod 12 are fixed on the connecting plate 11, a push plate 20 is fixed on the telescopic end of the first cylinder 19, the push plate 20 is slidably connected to the support rod 12, the support rod 12 is slidably connected to the suction cup 17, and a first spring 18 abutting against the suction cup 17 is fixed inside the support rod 12.

[0028] In detail, a limit groove is provided in the support rod 12, and a limit rod slidably connected to the limit groove is fixed on the suction cup 17. The first spring 18 is in a compressed state, so that the suction cup 17 is located at the end of the stroke away from the connecting plate 11. Before grabbing the plate, the second cylinder 37 controls the distance between the connecting plate 11 and the rotating plate 1001 to be minimum, and the first cylinder 19 controls the distance between the pushing plate 20 and the connecting plate 11 to be minimum; when the plate needs to be adsorbed, at this time, the second cylinder 37 controls the connecting plate 11 to move in the direction away from the rotating plate 1001, and drives the support rod 12 to move, thereby controlling the synchronous movement of the suction cup 17 through the first spring 18, and the support rod 12 will also drive the extrusion rod 15 to move through the splicing and clamping assembly. When the suction cup 17 is in contact with the surface of the plate, the support rod 12 continues to move, so that the first spring 18 is compressed. When the extrusion rod 15 is in contact with the surface of the plate, the second cylinder 37 stops moving.

[0029] See also Figure 1-Figure 3 , Figure 4-Figure 10The splicing and pressing assembly includes a support plate 13 fixedly mounted on the end of the support rod 12, and a plurality of second slide grooves 1301 equidistantly distributed on the support plate 13 are provided, and a sliding block 14 is slidably mounted in the second slide groove 1301, and the sliding block 14 is fixedly connected to the extrusion rod 15. The lifting and unfolding mechanism includes a first movable sleeve 23 and a second movable sleeve 27 slidably mounted on the support rod 12, a first limiting ring 24 is rotatably mounted on the first movable sleeve 23, and a second limiting ring 28 is rotatably mounted on the second movable sleeve 27, and a second spring 22 and a third spring 2 are sleeved on the support rod 12. 6. The two ends of the second spring 22 are respectively in contact with the first movable sleeve 23 and the push plate 20, and the two ends of the third spring 26 are respectively in contact with the first limiting ring 24 and the second limiting ring 28. The first limiting ring 24 and the second limiting ring 28 are provided with a driven component, wherein the driven component includes a receiving plate 30 respectively fixed on the first limiting ring 24 and the second limiting ring 28, a receiving rod 31 is rotatably mounted on the receiving plate 30, a first connecting rod 35 and a second connecting rod 36 are hinged on the connecting rod 31, and the first connecting rod 35 and the second connecting rod 36 are respectively hinged to the sliding block 14.

[0030] See also Figure 1-Figure 6 , Figure 9-11 The yielding control mechanism includes a first guide groove and a second guide groove provided on the first movable sleeve 23 and the second movable sleeve 27. A follower rod 21 is fixed on the push plate 20. A first limit block 2101 and a second limit block 2102 are fixed on the follower rod 21. The first limit block 2101 is slidably engaged with the first guide groove, and the second limit block 2102 is slidably engaged with the second guide groove. A clamping assembly is provided on the receiving plate 30, wherein the clamping assembly includes a clamping assembly fixed on the receiving plate 30. A fixed latch tooth 3001 is provided on the receiving rod 31, a sliding sleeve 32 is slidably installed on the receiving rod, a limiting latch tooth 3201 and a movable plate 33 are fixed on the sliding sleeve 32, the locking assembly also includes a fourth spring 34 sleeved on the receiving rod 31, the fourth spring 34 abuts against the movable plate 33, the first movable sleeve 23 and the second movable sleeve 27 are respectively fixed with a first rotating ring 25 and a second rotating ring 29, the first rotating ring 25 and the second rotating ring 29 are respectively abutted against the movable plate 33.

[0031] It should be noted that the first guide groove can be divided into two sections, namely the first spiral groove 2301 and the first vertical groove 2302, and the second guide groove is also divided into two sections, namely the second spiral groove 2701 and the second vertical groove 2702. The first connecting rod 35 and the second connecting rod 36 have the same size. In the initial state, under the action of the first cylinder 19, the distance between the push plate 20 and the connecting plate 11 is minimized. Under the action of the follower rod 21, the first limit block 2101 is located on the side of the first spiral groove 2301 away from the first vertical groove 2302, and the second limit block 2102 is located on the side of the second spiral groove 2701 away from the second vertical groove 2702, so that the first movable sleeve 23 and the second movable sleeve 27 are located at the end of the stroke in the direction of the connecting plate 11. At this time, the first rotating ring 25 and the second rotating ring 29 are at the movable plate 33. In the abutment state, the movable plate 33 is located at the end of the stroke away from the receiving plate 30 to compress the fourth spring 34. At the same time, the movable plate 33 will also control the limiting tooth 3201 and the fixed tooth 3001 to be in a separated state through the sliding sleeve 32, ensuring that the receiving rod 31 can rotate freely. The second spring 22 and the third spring 26 are both in a compressed state, and the elastic potential energy of the second spring 22 is greater than the elastic potential energy of the third spring 26. The distance between the first limiting ring 24 and the second limiting ring 28 and the support plate 13 is the largest, and the distance between the first limiting ring 24 and the second limiting ring 28 is the largest, so that the inclination angle of the first connecting rod 35 and the second connecting rod 36 is the same. Under the action of the first connecting rod 35 and the second connecting rod 36, the distance between the four sliding blocks 14 is minimized to minimize the distance between the extrusion rods 15.

[0032] When the plate needs to be adsorbed, since the plate is rectangular, it is necessary to control the plate to be placed at the center of the suction cup 17. Under the action of the positioning and clamping assembly, the plate is centrally positioned, and under the action of the positioning and clamping assembly, the shorter side of the plate is located at the matching position of the extrusion rod 15 connected to the second connecting rod 36, and the longer side of the plate is located at the matching position of the extrusion rod 15 connected to the first connecting rod 35. The second cylinder 37 works to move the suction cup 17 and the extrusion rod 15 toward the plate, and when the suction cup 17 and the extrusion rod 15 are both in contact with the surface of the plate, the second cylinder 37 stops working. At this time, the first cylinder 19 works, driving the push plate 20 to move, driving the follower rod 21 to move, thereby driving the first limit block 2101 and the second limit block 2102 to move, so that the first movable sleeve 23 and the second movable sleeve 27 are no longer restricted, and under the action of the second spring 22 and the third spring 26, the first movable sleeve 23 and the second movable sleeve 27 synchronously follow the movement of the push plate 20, and the position of the first limit block 2101 in the first spiral groove 2301 will not change, and the position of the second limit block 2102 in the second spiral groove 2701 will not change either.

[0033] Furthermore, the first movable sleeve 23 and the second movable sleeve 27 will also drive the first limiting ring 24 and the second limiting ring 28 to move synchronously, thereby driving the first connecting rod 35 and the second connecting rod 36 to move through the receiving plate 30 and the receiving rod 31, so as to control the four sliding blocks 14 to slide at the same speed along the length direction of the second sliding groove 1301, and move in the direction away from each other. The sliding block 14 will also drive the extrusion rod 15 and the limiting column 16 to move. When the limiting column 16 connected to the second connecting rod 36 moves to the position of abutting and cooperating with two of the positioning plates 6, it means that two of the extrusion rods 15 move to the extrusion and fitting position required for the narrower side of the plate. Under the action of the limiting column 16, the two extrusion rods 15 located on the narrow side no longer move, so that the second connecting rod 36, the receiving plate 30, and the second rotating ring 29 connected thereto remain in a fixed state, and the position of the second movable sleeve 27 on the support rod 12 no longer changes, pushing the plate 20 continues to move. Since the elastic potential energy of the second spring 22 is greater than the elastic potential energy of the third spring 26, the second spring 22 will push the first movable sleeve 23 to continue to move. Since the second movable sleeve 27 no longer moves, the third spring 26 will be compressed. At the same time, the second limit block 2102 will slide along the second spiral groove 2701, so that the second movable sleeve 27 rotates a certain angle to rotate the second limit ring 28, and the second limit ring 28 will be separated from two of the movable plates 33 matched therewith. The fourth spring 34 has elastic potential energy and pushes the sliding sleeve 32 to move through the movable plate 33, so that the limit tooth 3201 moves toward the fixed tooth 3001 until the limit tooth 3201 is engaged with the fixed tooth 3001. Under the action of the limit tooth 3201 and the fixed tooth 3001, two of the receiving rods 31 matched therewith are locked to ensure that the second connecting rod 36 no longer moves.

[0034] Subsequently, the first movable sleeve 23 continues to move, causing the other two extrusion rods 15 and the limiting column 16 located on the longer sides of the plate to continue to move, until the limiting column 16 also moves to the abutment position with the other two positioning plates 6. At this time, the first connecting rod 35, the receiving plate 30, the first rotating ring 25, and the first movable sleeve 23 connected thereto no longer move, and the pushing plate 20 continues to move and compresses the second spring 22. At the same time, the pushing plate 20 will also drive the first limiting block 2101 to slide in the first spiral groove 2301, causing the first movable sleeve 23 to rotate so as to rotate the first limiting ring 24. Similarly, the first limiting ring 24 will be separated from the other two movable plates 33 cooperating therewith, causing the limiting tooth 3201 cooperating with the movable plate 33 to move to the engaging position with the fixed tooth 3001, thereby locking the receiving rod 31 so that the first connecting rod 35 no longer moves.

[0035] When the four extrusion rods 15 move to the required pressure positions on the four sides of the plate, they will be locked in position. At this time, the air pressure of the suction cup 17 can be adjusted so that the suction cup 17 is in a negative pressure state to adsorb the plate. At the same time, under the action of the second cylinder 37, the plate is lifted to the required position by the suction cup 17, and under the action of the rotating rod 10, the plate is controlled to flip to a position parallel to the wall by the suction cup 17. The second cylinder 37 continues to move and controls the plate to move toward the wall through the suction cup 17 until the plate fits the wall. Under the action of the extrusion rod 15, multi-point extrusion force can be provided to the plate to ensure smooth assembly of the plate. The rotating rod 10 can be driven by a motor. This is an application of the prior art and will not be elaborated in this application.

[0036] Preferably, by adaptively adjusting the positions of the four extrusion rods 15 before adsorbing the sheet, and locking the position of the extrusion rods 15 after they move to the desired position, an adaptive adaptation auxiliary installation effect for sheets of different specifications can be achieved. During the assembly of the sheet on the wall, the extrusion rods 15 can provide the sheet with multi-point, uniform extrusion thrust to ensure that the sheet is assembled smoothly and accurately. At the same time, this multi-point pressure method can also effectively prevent the sheet from warping or breaking due to excessive or uneven force, thereby ensuring the quality and stability of sheet assembly.

[0037] A high-precision automatic splicing method of ALC plates based on positioning guide rails includes the following steps: Step 1: Place the required plate on the lifting plate 5, and position the plate under the action of the positioning clamping assembly; Step 2: Under the action of the adsorption flipping assembly, the suction cup 17, the splicing and pressing assembly, and the extrusion rod 15 are controlled to move toward the plate; Step 3: When the suction cup 17 and the extrusion rod 15 are in contact with the plate, the adsorption flip assembly will adjust the position of the extrusion rod 15 through the lifting and unfolding mechanism, and lock the position of the extrusion rod 15 under the action of the yielding control mechanism; Step 4: The adsorption flip component controls the suction cup 17 to be lifted to a certain height and then flipped to a position parallel to the wall, and pushes the suction cup 17 and the squeezing rod 15 to move toward the wall, so as to perform a pressing action on the plate through the squeezing rod 15.
