Compared to manual and semi-automatic cutting methods, CNC cutting effectively improves efficiency and quality while reducing operator workload. Currently, with the accelerating pace of industrialization, my country's demand for stone products continues to rise, and the requirements for efficiency and quality in stone cutting are also increasing. Therefore, the market potential for CNC cutting machines remains significant, and the market outlook is relatively optimistic.

[0003] When performing CNC cutting, it usually takes two workers to lift the stone slab onto the conveyor mechanism, which not only reduces productivity but also increases enterprise costs. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is: when performing CNC cutting, it is usually necessary to rely on two workers to lift the stone slab onto the conveying mechanism, which not only reduces productivity but also increases enterprise costs.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: an automatic plate suction device, comprising:

[0006] The adsorption mechanism includes a suction plate and a negative pressure member; a plurality of negative suction holes are opened on one surface of the suction plate, and the negative pressure member can absorb air through the plurality of negative suction holes;

[0007] a lifting mechanism, wherein the lifting mechanism can control the suction plate to move in a vertical direction; and

[0008] A horizontal driving mechanism is provided, wherein the horizontal driving mechanism can drive the lifting mechanism to move in a horizontal direction.

[0009] In the present invention, the suction plate is controlled to move in the vertical direction by the lifting mechanism, and the lifting mechanism is controlled to move in the horizontal direction by the horizontal driving mechanism, thereby driving the suction plate to move in the horizontal direction, so that the side of the suction plate with the negative suction hole is in contact with the upper end surface of the stone, and then the negative pressure piece is controlled to move, and the negative pressure piece sucks air through the multiple negative suction holes, so that negative pressure is generated between the stone and the negative suction holes, thereby fixing the stone on the suction plate; and then the lifting mechanism and the horizontal driving mechanism are used to transport the stone to the conveying mechanism via the suction plate, thereby completing the transportation of the stone and replacing manual handling, thereby effectively improving the production efficiency of the stone and effectively saving production costs.

[0010] Preferably, the lifting mechanism includes a cylinder and a mounting beam; one end of the cylinder is mounted on the lifting mechanism, and the other end of the cylinder is mounted on the mounting beam, and the suction plate is mounted on the mounting beam. The cylinder drives the mounting beam to move up and down, thereby driving the suction plate to move up and down.

[0011] Preferably, the adsorption mechanism is provided in plurality, and the plurality of adsorption mechanisms are arranged along a straight line. The plurality of adsorption mechanisms are provided so that a plurality of stones can be loaded at one time, thereby improving the loading efficiency.

[0012] Preferably, the suction plate is mounted on the mounting beam via a connecting mechanism comprising a connecting sleeve and a threaded rod. The suction plate is mounted on the connecting sleeve, which is slidably mounted on the mounting beam. One end of the threaded rod passes through the threaded sleeve and abuts against the mounting beam, and the threaded rod and the sliding sleeve are threadedly connected. By adjusting the position of the sliding sleeve on the mounting beam, the spacing between the multiple suction plates can be adjusted, thereby adjusting the spacing of the stone material. After adjustment, the sliding sleeve is fixed by rotating the threaded rod to make it abut against the mounting beam.

[0013] Preferably, the suction plate is mounted on the connecting sleeve via a buffer mechanism, the buffer mechanism comprising a connecting rod, a spring, and a nut; one end of the connecting rod is fixedly connected to the suction plate, the other end of the connecting rod slides through the connecting sleeve, and the connecting rod and the suction plate are arranged perpendicularly, the spring is sleeved on the connecting rod and located between the suction plate and the connecting sleeve, and the two nuts are mounted on the end of the connecting rod away from the suction plate, and the two nuts are threadedly connected to the connecting rod. When the suction plate moves downward, the suction plate drives the connecting rod to move, causing the connecting rod to slide within the connecting sleeve, thereby squeezing the spring through the connecting sleeve and the suction plate, thereby achieving a buffering effect, so that when the suction plate contacts the stone, it can effectively buffer the stone, thereby effectively preventing the suction plate from damaging the stone when contacting the stone; the initial buffering force can be adjusted by adjusting the position of the two nuts on the connecting rod.

[0014] Preferably, the horizontal drive mechanism includes a bracket, a sliding rod, a sliding sleeve, a chain, a transmission sprocket, a drive sprocket, and a driving member; the sliding rod is fixedly mounted on the bracket; the lifting mechanism is mounted on the sliding sleeve, the sliding sleeve is slidably mounted on the sliding rod, the chain is mounted on the sliding rod via a connection transmission sprocket, and the chain is arranged along the length direction of the sliding rod, the transmission sprocket is rotatably mounted on the sliding rod; the drive sprocket is rotatably mounted on the sliding sleeve, and the drive sprocket cooperates with the chain, and the driving member can drive the sprocket to rotate. The driving member drives the drive sprocket to rotate, and the sprocket drives the sliding sleeve to slide on the sliding rod through the chain that cooperates with it, so that the sliding sleeve drives the lifting mechanism to move in the horizontal direction.

[0015] Preferably, a switch mechanism is installed in each of the negative suction holes, and the switch mechanism includes a sealing plate, a push plate, a push block, and a reset member; the sealing plate is located in the negative suction hole, one end of the sealing plate is hinged to the suction plate, and when the sealing plate is perpendicular to the inner side wall of the negative suction hole, the sealing member closes the negative suction hole; a slide groove is provided on the suction plate, one end of the push block is slidably installed in the slide groove, and the other end of the push block extends out of the slide groove; one end of the push plate is fixedly connected to the sealing plate, and the other end of the push plate extends into the slide groove; the reset member applies a downward force to the push plate. This can effectively prevent air leakage when some negative suction holes are not in contact with the stone, thereby effectively preventing the stone from being unstable.

[0016] Preferably, the switch mechanism further comprises a circular baffle, wherein the suction plate has a circular groove formed therein, the circular groove being in communication with the negative suction hole and the chute, and the circular baffle and the circular groove being engaged with each other. The circular baffle and the sealing plate are coaxially arranged at the hinge, and the circular baffle and the sealing plate are fixedly connected. By providing the circular baffle and the engaged circular groove at the hinge, gas leakage from the hinge through the chute can be effectively prevented.

[0017] Preferably, a limiting surface is provided at one end of the sealing plate away from the hinge point, and when the sealing plate is perpendicular to the inner side wall of the negative suction hole, the limiting surface abuts against the inner side wall of the negative suction hole to limit the sealing plate from rotating upward, and a rubber sheet is installed at the edge of the sealing plate. By providing the limiting surface on the sealing plate, when the sealing plate closes the negative suction hole and the negative pressure member is working, the limiting surface can limit the sealing plate from rotating upward and leaking air under the action of negative pressure, and the sealing plate tends to rotate upward under the action of negative pressure. The limiting surface cooperates with the rubber sheet, so that the sealing plate can further squeeze the rubber sheet to improve the airtightness between the sealing plate and the negative suction hole.

[0018] Preferably, the reset member includes a first magnet and a second magnet, wherein the first magnet is fixedly mounted on the suction plate, and the second magnet is fixedly mounted on the push plate, and the magnetic poles of the first magnet and the second magnet are in opposite directions. A downward force is applied to the push plate by the repulsive force between the first magnet and the second magnet.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] 1. It can effectively improve the production efficiency of stone and effectively save production costs. In the present invention, the suction plate is controlled to move in the vertical direction by the lifting mechanism, and the lifting mechanism is controlled to move in the horizontal direction by the horizontal driving mechanism, thereby driving the suction plate to move in the horizontal direction, so that the side of the suction plate with the negative suction hole is in contact with the upper end surface of the stone, and then the negative pressure piece is controlled to move, and the negative pressure piece sucks air through the multiple negative suction holes, so that negative pressure is generated between the stone and the negative suction holes, thereby fixing the stone on the suction plate; then the lifting mechanism and the horizontal driving mechanism are used to transport the stone to the conveying mechanism through the suction plate, thereby completing the transportation of the stone, replacing manual handling, thereby effectively improving the production efficiency of the stone and effectively saving production costs.

[0021] 2. It can effectively prevent the phenomenon of unstable stone fixation caused by some negative suction holes not fitting with the stone. In the present invention, when the suction plate contacts the upper end face of the stone, the stone pushes the push block to move toward the slide groove, while overcoming the force applied by the reset member. The push block pushes the push plate to rotate, and the push plate drives the sealing plate to rotate, leaving space for the gas to pass through, thereby opening the negative suction hole, and the negative pressure member sucks air through the negative suction hole to fix the stone on the suction plate; when the upper end face of the stone is partially concave, the push block does not move, and the sealing plate is perpendicular to the inner wall of the negative suction hole, so the negative suction hole is always in a closed state, thereby effectively preventing air leakage when some negative suction holes are not fitting with the stone, thereby effectively preventing the phenomenon of unstable stone fixation.
