Description

Technical Field

[0001] This utility model relates to the field of stone slab conveying technology, and in particular to a stone slab gripping and conveying device. Background Technology

[0002] In automated slate processing lines, slates typically arrive in stacks. Robots or gantry cranes use negative pressure suction cups to remove the top layer of slates one by one and deliver them to subsequent lamination, drilling, or laser cutting stations. As the production line cycle time increases, the suction cups must quickly complete the three actions of adsorption, lifting, and translation. The stacking height gradually decreases with production, and single-item errors are amplified cyclically, directly affecting the overall shift output.

[0003] Existing technologies generally use arrayed sponge suction cups in conjunction with vacuum pumps to increase the reliability of single-sheet suction by increasing negative pressure; some solutions add gap blowing nozzles around the suction cups in an attempt to inject compressed air between the stone slabs to break the vacuum adsorption layer between the two layers; and some production lines arrange mechanical striking blocks at the edge of the top layer of the slab, which form micro gaps by high-frequency striking with a cylinder.

[0004] However, increased negative pressure causes the stone slabs to deform and break, and the air blowing channels are easily blocked by stone powder, allowing only localized air blowing. Tapping also easily causes the stone slabs to break. None of these three methods can accurately separate two layers of stone slabs, and it is still impossible to prevent two or more slabs from being lifted up simultaneously. During the conveying process, the simultaneous suction causes two or even three slabs to be lifted and fall, leading to vacuum platform positioning failure, tool chipping, or pressure foot damage. This forces the production line to stop abruptly and requires manual slab picking, becoming the primary challenge restricting the continuous unmanned operation of stone slab processing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a stone slab grabbing and conveying device to solve the problem of simultaneous picking up of stacked stone slabs caused by vacuum negative pressure during adsorption.

[0006] To achieve the above objectives, this utility model provides a stone slab gripping and conveying device, which adopts the following technical solution: A stone slab grabbing and conveying device, comprising: The truss has blocking beams at both ends; the sliding frame is reciprocatingly mounted on the truss; the base frame is lifting and lowering mounted on the sliding frame, and the base frame is equipped with suction cups for adsorbing stone slabs; the telescopic mechanism is laterally mounted on one side of the base frame to push the stone slabs to one side; the first sliding mechanism and the second sliding mechanism are fixedly mounted on the sliding frame to drive the sliding frame and the base frame to move respectively.

[0007] By adopting the above technical solution, the truss and sliding frame form a high-speed translation frame, and the lifting of the base frame and the negative pressure of the suction cup work together to pick up the stone slab; before adsorption, the telescopic mechanism applies a slight lateral movement to the top layer of stone slab, which breaks the vacuum seal between the layers, allowing air to enter the gap in advance, eliminating negative pressure adhesion, thereby avoiding the simultaneous suction and achieving stable single sheet output.

[0008] Furthermore, the telescopic mechanism includes a protruding frame fixedly mounted on one side of the base frame, a first cylinder fixedly mounted on the protruding frame, and a lever that moves with the first cylinder. A first slider is provided on the piston rod of the first cylinder, and the lever moves up and down within the first slider.

[0009] By adopting the above technical solution, the combination of cylinder-slider-actuator forms a lateral micro-thrust. The actuator can float within the slider according to the thickness of the stone slab, avoiding rigid impact, ensuring consistent and repeatable micro-movement, and improving separation reliability.

[0010] Furthermore, a guide rail is fixedly provided at the bottom of the protruding frame, a second slider is slidably provided on the guide rail, a connecting plate is provided on the second slider to follow the movement of the second slider, the piston rod of the first cylinder is connected to the rotating shaft of the connecting plate, and the first slider is vertically mounted on the connecting plate.

[0011] By adopting the above technical solution, the guide rail and the second slider provide low-friction guidance for the cylinder, the connecting plate shaft structure absorbs off-center load, prevents the actuating rod from jamming, ensures smooth transmission of lateral thrust, and extends the life of the actuator.

[0012] Furthermore, the actuating lever includes a lifting rod that is slidably disposed within the first slider, a pressure rod that is vertically disposed at the bottom of the lifting rod, and a push plate that is fixedly disposed at the end of the pressure rod away from the stone slab.

[0013] By adopting the above technical solution, the lifting rod can move freely up and down within the slider, the pressure rod only provides a limit, the push plate contacts the side line of the plate, and the pressure rod does not apply downward pressure during the pushing process, thus avoiding bending or scratching of the stone slab and adapting to different thicknesses of slabs.

[0014] Furthermore, a second cylinder that extends downwards is fixedly installed on one side of the base frame, and a buffer assembly that abuts against the lower stone slab is provided on the piston rod of the second cylinder.

[0015] By adopting the above technical solution, the second cylinder drives the buffer assembly to move downward and gently presses down the lower plate, forming local damping, blocking the friction caused by the upper plate rising, and further reducing the risk of double tension.

[0016] Furthermore, the buffer assembly includes a sleeve screwed onto the piston rod of the second cylinder, a push rod telescopically disposed within the sleeve, and a first spring disposed between the push rod and the sleeve.

[0017] By adopting the above technical solution, the spring-top rod floating structure adapts to changes in plate thickness, providing a continuous and gentle clamping force, avoiding indentations on the plate surface caused by rigid top pressure, while ensuring that the lower plate is always stably pressed down.

[0018] Furthermore, the first sliding mechanism includes a roller rotatably mounted on the sliding frame, a first motor fixedly mounted on the sliding frame, and a roller shaft mounted on the first motor to drive the roller to rotate, wherein the roller is rotatably mounted on the truss.

[0019] By adopting the above technical solution, the motor-roller-roller form a closed-loop drive, and the roller meshes with the top and side walls of the truss at the same time, so as to achieve high-acceleration translation without deviation and improve the pick-and-place cycle.

[0020] Furthermore, the second sliding mechanism includes a longitudinal beam fixedly mounted on the base frame and passing through the sliding frame, a through hole vertically opened on the sliding frame for the longitudinal beam to move up and down, and an auxiliary wheel rotatably mounted on the side wall of the through hole and abutting against the longitudinal beam.

[0021] By adopting the above technical solution, the longitudinal beam and auxiliary wheel form a rolling guide rail, which significantly reduces the lifting friction, prevents the base frame from swaying, ensures the parallelism between the suction cup and the plate surface, and improves the consistency of adsorption.

[0022] Furthermore, a second motor is fixedly mounted on the sliding frame, and a reel is mounted on the drive end of the second motor. A pull belt is wound on the reel, with one end of the pull belt wrapped around the reel and the other end fixedly mounted on the base frame.

[0023] By adopting the above technical solution, the reel-belt system enables the lifting drive components to move upward, reducing the weight of the base frame and the load on the motor; the flexible winding and unwinding of the belt avoids rigid impacts, and the lifting stop position has high accuracy.

[0024] Furthermore, a guide block for lifting and lowering the suction cup is vertically arranged on the base frame, and a second spring is respectively arranged at the upper and lower ends of the guide block, with the two second springs sleeved on the suction cup.

[0025] By adopting the above technical solution, the double spring clamping suction cup forms a floating suction nozzle, which automatically compensates for the plate thickness deviation during the descent of the base frame, absorbs impact energy, prevents the suction cup from colliding hard with the plate surface, and extends the life of the sponge suction cup.

[0026] Compared with the prior art, the stone slab grabbing and conveying device of this utility model has the following advantages: The top slab is moved laterally by a telescopic mechanism to pre-break the vacuum seal between layers, allowing air to enter the gaps and eliminating adsorption at the source, thus achieving reliable single-sheet output. The cylinder-slider-toggle rod floating structure ensures gentle thrust and repeatable positioning, avoiding indentations or cracks on the slab surface and adapting to different thickness ranges. The second cylinder drives the buffer assembly to press down the lower slab, forming independent damping, further blocking friction and significantly reducing double-sheet rate. The reel-pulling belt lifting scheme moves the drive components upward, reducing the weight of the base frame, increasing lifting acceleration, and shortening cycle time. The longitudinal beam-auxiliary wheel rolling guide rail and the double-spring floating suction nozzle work together to ensure the parallelism between the suction cup and the slab surface, greatly reducing adsorption failure rate. The overall modular design allows all actuators to be installed on the base frame or sliding frame, providing a unified maintenance window and significantly reducing downtime for maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] This embodiment relates to a stone slab gripping and conveying device. In terms of overall structure, as follows... Figure 1 As shown, it includes a truss 1, a sliding frame 2, a base frame 3, and a telescopic mechanism 8.

[0035] Among them, the truss 1 is provided with blocking beams 4 at both ends, the sliding frame 2 is reciprocated on the truss 1, the sliding frame 2 is provided with a base frame 3 that is raised and lowered, the base frame 3 is provided with a suction cup 7 for adsorbing stone slabs, the stone slabs rise with the base frame 3 and move with the sliding frame 2, the base frame 3 is provided with a telescopic mechanism 8 for moving the stone slabs, and the sliding frame 2 is provided with a first sliding mechanism 5 and a second sliding mechanism 6 for driving the sliding frame 2 and the base frame 3 respectively.

[0036] It is worth mentioning that the truss 1 is set on one side of the stone slab processing equipment, such as a stone slab laminating equipment. The stone slabs are stacked at the bottom of the truss 1. The first drive mechanism drives the sliding frame 2 to move back and forth on the truss 1, moving the stone slabs from the stack to the processing equipment. The second drive mechanism is connected to the base frame 3, driving the base frame 3 to lift and lower the stone slabs. The arrangement of the sliding frame 2 ensures that the stone slabs can be lifted from the stack and transported to the processing equipment, thereby improving the automation of the equipment. Multiple sets of suction cups 7 are set on the base frame 3. After the base frame 3 descends to the stack, the suction cups 7 adsorb the stone slabs. To ensure the stone slabs can move with the base frame 3, the telescopic mechanism 8 is installed on one side of the base frame 3. When the base frame 3 descends to the stacking position, the telescopic mechanism 8 is located on one side of the stone slabs, and the top stone slab is slightly pushed to one side. This setting makes it easier for the stone slabs to be lifted. Since the stone slabs are stacked vertically, the two layers of stone slabs are too tightly attached, and air cannot enter between the two layers of stone slabs in time, thus creating a vacuum and friction. When adsorbing the upper stone slab, the lower stone slab is easily lifted. Therefore, the upper stone slab is slightly pushed to ensure that air can easily enter between the two stone slabs and to prevent the lower stone slab from being lifted.

[0037] Based on the above overall introduction, an exemplary structure of the stone slab gripping and conveying device in this embodiment is as follows: Figure 2 and Figure 4 As shown, the telescopic mechanism 8 includes a protruding frame 801 fixedly mounted on one side of the base frame 3, a first cylinder 802 fixedly mounted on the protruding frame 801, and a toggle lever 803 that moves with the first cylinder 802. A first slider 804 is provided on the piston rod of the first cylinder 802, and the toggle lever 803 is slidably mounted in the first slider 804. It should be noted that the protruding frame 801 and the base frame 3 are arranged vertically. The protruding frame 801 is welded to one side of the base frame 3. The actuating rod 803 can slide inside the protruding frame 801 under the push of the first cylinder 802. When the base frame 3 descends to the stack, the actuating rod 803 is located on one side of the stone slab. Then the actuating rod 803 retracts, pushing the stone slab to one side. The stone slab deviates from the side of the stack. The base frame 3 continues to descend until the suction cup 7 adsorbs the stone slab. During the descent of the base frame 3, the actuating rod 803 contacts the stone slab and slides inside the slider. This setting ensures that the stone slab is not subjected to the pressure of the actuating rod 803, thus avoiding damage to the stone slab.

[0038] As a preferred option, such as Figure 3 and Figure 4As shown, in this embodiment, a guide rail 805 is fixedly installed at the bottom of the protruding frame 801, and a second slider 806 is slidably installed on the guide rail 805. A connecting plate 807 that moves with the second slider 806 is installed on the second slider 806. The piston rod of the first cylinder 802 is connected to the rotating shaft of the connecting plate 807, and the first slider 804 is vertically installed on the connecting plate 807. Specifically, two guide rails 805 and two sliders 806 are provided respectively. The guide rails 805 are installed on both sides of the protruding frame 801. The connecting plate 807 and the two sliders are fixedly connected. The first cylinder 802 drives the connecting plate 807 to move, and the second slider 806 slides on the guide rail 805 following the connecting plate 807. The arrangement of the second slider 806 and the guide rail 805 can ensure the stability of the sliding of the connecting plate 807. The connecting plate 807 drives the first slider 804 to move. This arrangement ensures that the actuating rod 803 can actuate the stone slab.

[0039] As a preferred option, such as Figure 4 As shown, in this embodiment, the actuating lever 803 includes a lifting lever 8031 ​​slidably disposed within the first slider 804, a pressure lever 8032 vertically disposed at the bottom of the lifting lever 8031, and a push plate 8033 fixedly disposed at the end of the pressure lever 8032 away from the stone slab. Specifically, when the base frame 3 is pressed down, the pressure lever 8032 contacts the top surface of the stone slab, while the lifting lever 8031 ​​rises within the first slider 804 to prevent the pressure lever 8032 from applying excessive pressure to the stone slab. At this time, the push plate 8033 contacts the side of the stone slab. When the first cylinder 802 retracts the piston rod, the connecting rod drives the first slider 804 to move towards the base frame 3. The first slider 804 drives the lifting lever 8031 ​​to move, and the push plate 8033 pushes the stone slab slightly to one side of the stack. This arrangement enables slight movement of the stone slab, making it convenient for the suction cup 7 to lift the stone slab without affecting the lower stone slab.

[0040] In addition, such as Figure 10 As shown, at least two strip-shaped holes 14 are vertically opened on the push plate 8033. Bolts 15 are inserted into the strip-shaped holes 14 and are screwed to the pressure rod 8032. The purpose of opening the strip-shaped holes 14 is to ensure that the height of the push plate 8033 can be adjusted on the pressure rod 8032. This setting can push stone slabs of different thicknesses. After the push plate 8033 is adjusted to the correct position, it is fixed to the pressure rod 8032 by tightening the bolts 15 and the pressure rod 8032, thereby improving the strength of the push rod and making it easier to adjust the position of the push plate 8033.

[0041] As a preferred option, such as Figure 5As shown, in this embodiment, a downwardly extending second cylinder 9 is provided on one side of the protruding frame 801. A buffer assembly 10 that abuts against the lower stone slab is provided on the piston rod of the second cylinder 9. Specifically, the function of the second cylinder 9 is that when the actuating rod 803 pushes the upper stone slab to one side, the piston rod of the second cylinder 9 drives the buffer assembly 10 to descend and abut against the lower stone slab. When the base frame 3 drives the upper stone slab to rise, the buffer assembly 10 can hold the lower stone slab in place, preventing the lower stone slab from moving with the upper stone slab and thus affecting the adsorption of the stone slab in the next operation.

[0042] As a preferred implementation method, such as Figure 6 As shown, the buffer assembly 10 in this embodiment includes a sleeve 1001 screwed onto the piston rod of the second cylinder 9, a push rod 1002 telescopically disposed within the sleeve 1001, and a first spring 1003 disposed between the push rod 1002 and the sleeve 1001. It should be noted that the top end of the sleeve 1001 has a threaded groove, the piston rod of the second cylinder 9 is screwed into the threaded groove, and a piston is disposed on the push rod 1002. The piston moves within the sleeve 1001, achieving a buffering effect. A venting hole 602 is provided on the sleeve 1001 or the piston to ensure that the piston can slide within the sleeve 1001. The first spring 1003 ensures that the push rod 1002 always remains in contact with the stone slab. When the second cylinder 9 descends, the buffer assembly 10 provides a buffering effect, preventing damage to the stone slab from the second cylinder 9. When the base frame 3 rises, the first spring 1003 can still push the push rod 1002 to contact the stone slab.

[0043] As a preferred implementation method, such as Figure 7 As shown, in this embodiment, the first sliding mechanism 5 includes a roller 501 rotatably mounted on the sliding frame 2, a first motor 502 fixedly mounted on the sliding frame 2, and a roller shaft 503 mounted on the first motor 502 to drive the roller 501 to rotate. The roller 501 is rotatably mounted on the truss 1. It should be noted that multiple sets of rollers 501 are provided, respectively located at the top and both sides of the truss 1. This arrangement ensures the stability of the sliding frame 2 during movement. The roller shaft 503 is used to connect the rollers 501 at both ends of the sliding frame 2. The roller shaft 503 is keyed to the first motor 502. The first motor 502 drives the roller shaft 503 to rotate, and the roller shaft 503 drives the roller 501 to rotate, thereby realizing the movement of the sliding frame 2 along the truss 1.

[0044] As a preferred implementation method, such as Figure 7 and Figure 8As shown, the second sliding mechanism 6 in this embodiment includes a longitudinal beam 601 fixedly mounted on the base frame 3 and passing through the sliding frame 2, a through hole 602 vertically opened on the sliding frame 2 for the longitudinal beam 601 to rise and fall, and auxiliary wheels 603 rotatably mounted on the side wall of the through hole 602 and abutting against the longitudinal beam 601. It should be noted that there are two longitudinal beams 601 opposite each other on the top of the base frame 3, and the number of through holes 602 is the same as the number of longitudinal beams 601. The longitudinal beams 601 slide and rise within the through holes 602 to ensure the stability of the base frame 3 during rise and fall. An opening is provided on the side wall of the through hole 602, and the auxiliary wheels 603 are rotatably mounted within the opening. At least four auxiliary wheels 603 are provided on the side wall of the through hole 602 to ensure that the longitudinal beam 601 can abut against the four auxiliary wheels 603, thereby improving the stability of the longitudinal beam 601 during rise and fall.

[0045] As a preferred option, such as Figure 8 As shown, in this embodiment, a second motor 604 is fixedly installed on the sliding frame 2, and a reel 605 is installed at the drive end of the second motor 604. A pull belt 606 is wound on the reel 605, with one end of the pull belt 606 wrapped around the reel 605 and the other end fixedly installed on the base frame 3. Specifically, the second motor 604 is installed in the middle of the sliding frame 2. When the second motor 604 is started, it drives the reel 605 to rotate. The reel 605 drives the pull belt 606 to retract and extend. When the pull belt 606 retracts, the base frame 3 rises. When the pull belt 606 extends, the base frame 3 descends. This arrangement provides power for the lifting and lowering of the base frame 3. The purpose of installing the second motor 604 in the middle is to ensure the uniformity of power distribution and avoid unevenness. In conjunction with the lifting and lowering of the longitudinal beam 601, it improves the stability of the lifting and lowering of the base frame 3. A screw 13 is horizontally screwed onto the sliding frame 2. When the sliding frame 2 slides to the blocking beam 4, the screw 13 abuts against the blocking beam 4 to prevent the sliding frame 2 from hitting the blocking beam 4, thereby improving safety. The screw 13 can be adjusted on the base frame 3 to adjust the stopping position of the sliding frame 2.

[0046] As a preferred option, such as Figure 9 As shown, in this embodiment, a guide block 11 for lifting and lowering the suction cup 7 is vertically arranged on the base frame 3. A second spring 12 is respectively provided at the upper and lower ends of the guide block 11, and the two second springs 12 are sleeved on the suction cup 7. Specifically, the guide block 11 has a guide hole for lifting and lowering the suction cup 7. A vent pipe is provided at the top of the suction cup 7, and the vent pipe moves up and down within the guide hole. The top end of the vent pipe abuts against one of the second springs 12, and the bottom end abuts against the other second spring 12. When the base frame 3 descends, the lower second spring 12 is compressed; when the base frame 3 rises, the upper second spring 12 is compressed. This arrangement ensures that the suction cup 7 has a certain lifting and lowering space, providing a certain amount of cushioning force.

[0047] The slab grabbing and conveying equipment in this embodiment uses a telescopic mechanism 8 to slightly move the top slab laterally, pre-breaking the interlayer vacuum seal and allowing air to enter the slab gaps, eliminating adsorption at the source and achieving reliable single-sheet output. The floating structure of cylinder-slider-actuator 803 ensures gentle thrust and repeatable positioning, avoiding slab surface indentations or cracks, and adapting to different thickness ranges. The second cylinder 9 drives the buffer assembly 10 to press down the lower slab, forming independent damping, further blocking friction and significantly reducing double-sheet rate. The lifting scheme of reel 605-pull belt 606 moves the drive component upward, reducing the weight of the base frame 3, increasing lifting acceleration, and shortening cycle time. The longitudinal beam 601-auxiliary wheel 603 and the rolling guide rail 805 work together with the double-spring floating suction nozzle to ensure the parallelism between the suction cup 7 and the slab surface, greatly reducing adsorption failure rate. The overall modular design allows all actuators to be installed on the base frame 3 or sliding frame 2, unifying maintenance windows and significantly shortening downtime for maintenance.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
