Description

Technical Field

[0001] This application relates to the field of stone processing technology, and in particular to an intelligent automatic unloading device. Background Technology

[0002] Slab unloading is an important step in stone processing, which involves transferring the cut slabs from the cutting station to a conveying device for subsequent inspection, stacking, or further processing.

[0003] In related technologies, a handling device is usually used to pick up and transfer the cut stone slabs. However, in actual operation, due to the limited space between the cutting components and the support platform, the handling device or the stone slab is prone to collision or scratch with the cutting components during the movement of the handling device. This can not only easily cause damage or fall of the stone slab surface, but may also damage the cutting components, affecting the stability of the processing and production efficiency. Summary of the Invention

[0004] This application provides an intelligent automatic unloading device to solve the problem that interference easily occurs between the handling components and the cutting components during the unloading process of stone slabs, resulting in damage to the stone slabs or poor processing stability.

[0005] On the one hand, this application provides an intelligent automatic unloading device, including a support platform, and a cutting component and a conveying component disposed on the support platform;

[0006] The support platform is used at least to support the stone to be cut;

[0007] The cutting assembly includes a mounting bracket and a cutting component, the mounting bracket being movable relative to the support platform along a first direction;

[0008] The cutting element is movably disposed on the mounting bracket along the second direction, and the cutting element is used at least for cutting the stone.

[0009] The transport assembly includes a movable frame and a fixing component, the movable frame being movable relative to the support platform along the first direction;

[0010] The fixing member is movably disposed on the movable frame along the third direction to adjust the height position of the fixing member; the fixing member can pass over the cutting assembly and perform a picking operation on the stone slab formed by the stone cutting.

[0011] The first direction, the second direction, and the third direction are all perpendicular to each other.

[0012] By adopting the above technical solution, the intelligent automatic unloading device includes a support platform, and a cutting component and a conveying component disposed on the support platform. The support platform is used to support the stone to be cut. The cutting component has a mounting bracket and a cutting element. The mounting bracket can move relative to the support platform along a first direction, and the cutting element can move on the mounting bracket along a second direction for cutting the stone. The conveying component has a moving frame and a fixing element. The moving frame can move relative to the support platform along the first direction, and the fixing element can rise and fall on the moving frame along a third direction to change its height position. During the movement, the fixing element can pass over the cutting component to pick up the cut stone slab. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0013] In the specific implementation process, after the cutting component completes the cutting of the stone slab, the moving frame of the transport component approaches the support platform along the first direction. The fixing component is adjusted to a suitable height by lifting and lowering along the third direction. After passing over the cutting component, the stone slab is picked up. Then, the stone slab is carried away from the support platform along the first direction to complete the unloading action.

[0014] Understandably, compared to related technologies where there is a risk of interference between the moving path of the transport component and the cutting component, the intelligent automatic unloading device of this application embodiment, through the height-adjustable design of the fixing component along a third direction, enables the fixing component to cross over the cutting component to perform the picking operation. This achieves spatial layering of the transport path and the cutting area in the height direction, reduces the waiting time between processes, lowers the risk of collision between the slab and the cutting component, and improves the work efficiency and safety of the unloading process.

[0015] In some embodiments of this application, the third direction is parallel to the height direction, and the fastener has a first height and a second height in the third direction;

[0016] When the fixing member is at the first height, the height of the fixing member is lower than the height of the cutting assembly, so as to place the stone slab on the conveying device;

[0017] When the fixing member is at the second height, the height of the fixing member is higher than the height of the cutting assembly, so that the fixing member crosses over the cutting assembly during the process of moving towards the support platform and during the process of carrying the stone slab away from the support platform.

[0018] In some embodiments of this application, before the fixing member approaches the support platform along the first direction to pick up the stone slab, it rises from the first height position to the second height position, so that the fixing member is higher than the cutting component in the third direction;

[0019] After the stone slab is removed, the fastener holds the stone slab at the second height, carrying it away from the support platform along the first direction, so as to pass over the cutting assembly.

[0020] In some embodiments of this application, after the fixing member carries the picked-up stone slab across the cutting assembly, it descends from the second height to the first height to place the picked-up stone slab on the conveying device.

[0021] In some embodiments of this application, when the fixing member removes the stone slab, the cutting component moves away from the support platform along the first direction to form a removal space in the first direction.

[0022] In some embodiments of this application, the fixing member includes a pick-and-place portion for fixing the stone slab, the pick-and-place portion being rotatable about an axis parallel to the second direction;

[0023] When the pick-up and place part rotates to the first posture, the pick-up and place part faces the first direction to fix the vertical stone slab.

[0024] When the pick-and-place section rotates to the second posture, the pick-and-place section faces downwards to place the stone slab horizontally.

[0025] In some embodiments of this application, after the picking and placing part picks up the stone slab, it first rotates around the axis above the support platform from the first posture to the second posture, changing the stone slab from a vertical state to a horizontal state;

[0026] After the flip is completed, it moves away from the support platform along the first direction and crosses over the cutting component.

[0027] In some embodiments of this application, after the taking-up part takes up the stone slab, during the process of moving away from the support platform along the first direction, it rotates around the axis from the first posture to the second posture, changing the stone slab from a vertical state to a horizontal state.

[0028] In some embodiments of this application, during the process of the pick-and-place unit rotating from the first posture to the second posture, the stone slab being picked up is higher than the cutting component in the third direction.

[0029] In some embodiments of this application, when the fastener crosses the cutting assembly, the fastener has a safe distance between itself and the cutting assembly in the third direction;

[0030] The safety distance is greater than the thickness of the stone slab, or the safety distance is greater than half the width of the stone slab. Attached Figure Description

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] The intelligent automatic unloading device is an automated equipment used in the stone processing industry. It can automatically pick up and transfer stone slabs after cutting. Through the coordinated operation of the handling and cutting components, the device achieves mechanized unloading of cut stone slabs, replacing traditional manual handling methods. It is suitable for stone processing scenarios such as architectural decoration, landscaping, and home countertops.

[0042] In related technologies, slate processing equipment typically integrates a support platform, a cutting assembly, and a conveying assembly. The support platform holds the stone to be cut, while the cutting assembly cuts the stone, separating the slate from the main stone body. The conveying assembly has a movable frame and a fixing component for picking up the slate. The conveying assembly moves the fixing component to the location of the slate via the frame, where the fixing component picks up the slate and transfers it to a subsequent conveying device.

[0043] Furthermore, in the related technology, the movement path of the transport component during the process of picking up the stone slab near the support platform and carrying the stone slab away from the support platform intersects with the spatial area where the cutting component is located. To avoid collisions with the cutting component, the transport component must wait until the cutting component has completely exited the area near the support platform before it can perform the picking action, resulting in a long waiting interval between the cutting and unloading processes.

[0044] However, this method of waiting for the cutting components to retract prevents the cutting and unloading processes from being seamlessly integrated, increasing the time of each work cycle. Furthermore, if the height of the transport components is not properly controlled during movement, the fixing parts or the stone slab being picked up may still scrape or collide with the cutting components, causing damage to the stone slab surface or even causing the stone slab to fall off, affecting the stability of the processing and the quality of the finished product.

[0045] Based on the above-mentioned situation and problems, this application provides an intelligent automatic unloading device to achieve spatial avoidance and process connection in the stone slab unloading process. This intelligent automatic unloading device includes a support platform, and a cutting component and a conveying component disposed on the support platform. The support platform is used to support the stone to be cut. The cutting component has a mounting bracket and a cutting element. The mounting bracket can move relative to the support platform along a first direction, and the cutting element can move on the mounting bracket along a second direction for cutting the stone. The conveying component has a moving frame and a fixing element. The moving frame can move relative to the support platform along the first direction, and the fixing element can rise and fall on the moving frame along a third direction to change its height position. During the movement, the fixing element can pass over the cutting component to pick up the cut stone slab. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0046] In the specific implementation process, after the cutting component completes the cutting of the stone slab, the moving frame of the transport component approaches the support platform along the first direction. The fixing component is adjusted to a suitable height by lifting and lowering along the third direction. After passing over the cutting component, the stone slab is picked up. Then, the stone slab is carried away from the support platform along the first direction to complete the unloading action.

[0047] Understandably, compared to related technologies where there is a risk of interference between the moving path of the transport component and the cutting component, the intelligent automatic unloading device of this application embodiment, through the height-adjustable design of the fixing component along a third direction, enables the fixing component to cross over the cutting component to perform the picking operation. This achieves spatial layering of the transport path and the cutting area in the height direction, reduces the waiting time between processes, lowers the risk of collision between the slab and the cutting component, and improves the work efficiency and safety of the unloading process.

[0054] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0055] See Figure 1 , Figure 2 and Figure 3 This application provides an intelligent automatic unloading device, which may include a support platform 100, and a cutting component 200 and a conveying component 300 disposed on the support platform 100.

[0056] The support platform 100 is a basic platform component used to support the stone 10 to be cut. The support platform 100 can provide stable support for the stone 10, ensuring that the stone 10 maintains the preset posture and position during the cutting operation. At the same time, it provides an installation base for the cutting component 200 and the handling component 300, so that the cutting component 200 and the handling component 300 can move relative to each other with the support platform 100 as the reference.

[0057] For example, the support platform 100 can be configured as a frame structure with a flat upper surface, the upper surface of which forms a support area on which the stone 10 is placed. The support platform 100 can be provided with a guide rail structure for guiding the cutting assembly 200 and the conveying assembly 300 to move in a preset direction. The support area of ​​the support platform 100 can be provided with a positioning structure, such as a stop, positioning pin, or clamping element, for positioning and fixing the stone 10 to prevent the stone 10 from shifting during the cutting process.

[0058] The cutting assembly 200 is a functional component used to cut the stone 10. By cutting the stone 10, the cutting assembly 200 creates a separation interface between the stone slab 11 and the main body of the stone 10, thereby separating the stone slab 11 from the main body of the stone 10. The cutting assembly 200 is mounted on the support platform 100 and can be adjusted in position relative to the support platform 100 and the stone 10 on the support platform 100 to accommodate the cutting requirements of stones 10 of different thicknesses and the feed requirements at different stages of the cutting process.

[0059] The cutting assembly 200 may include a mounting bracket 210 and a cutting element 220. The mounting bracket 210 is a frame structure component in the cutting assembly 200 used to support and carry the cutting element 220. The mounting bracket 210 is movable relative to the support platform 100 along a first direction. The mounting bracket 210 provides a mounting base for the cutting element 220, allowing the cutting element 220 to move closer to or further away from the stone 10 on the support platform 100 along the first direction with the mounting bracket 210. This controls the relative position between the cutting element 220 and the stone 10, enabling adjustment of the cutting feed depth and retraction of the cutting element 220 after cutting.

[0060] For example, the mounting bracket 210 can be configured as a gantry frame or cantilever bracket spanning the support platform 100. The mounting bracket 210 can slide along a first direction by engaging with a guide rail on the support platform 100 via a slider.

[0061] The movement of the mounting bracket 210 can be achieved by a drive mechanism, which may include a motor, lead screw, rack and pinion, or hydraulic cylinder. The range of movement of the mounting bracket 210 along the first direction can be set according to the size of the stone 10 and the stroke requirements of the cutting piece 220. The upper limit of the movement range can be greater than the size of the bearing area in the first direction, so that the cutting piece 220 can completely exit above the bearing area.

[0062] The cutting element 220 is movably mounted on the mounting bracket 210 along a second direction. The cutting element 220 is a tool component in the cutting assembly 200 that directly cuts the stone 10. The movable mounting of the cutting element 220 along the second direction allows it to move laterally on the mounting bracket 210, thereby covering the area of ​​the stone 10 to be processed in the second direction and cutting different positions of the stone 10. The cutting element 220 is used at least to cut the stone 10, forming a cutting slit in the stone 10, allowing the stone slab 11 to be separated from the main body of the stone 10.

[0063] For example, the cutting element 220 may include a body and a cutting disc. The body can drive the cutting disc to rotate about the height direction, and the cutting disc may be a circular saw blade. The cutting element 220 can be mounted on the mounting bracket 210 via a movable bracket, and the movable bracket and the mounting bracket 210 are connected by a guide rail, so that the cutting element 220 can move smoothly in the second direction.

[0064] The movement of the cutting component 220 can be driven by a servo motor in conjunction with a lead screw, or by a synchronous belt drive or a linear motor. The height of the cutting disc can be adjusted by changing the mounting height of the cutting component 220 on the mounting bracket 210, or by moving the mounting bracket 210 along the first direction.

[0065] The handling assembly 300 is a functional component used to pick up the cut stone slab 11 from the support platform 100 and transfer it to the subsequent conveying device. Through moving and fixing actions, the handling assembly 300 completes the automated unloading operation of the stone slab 11, realizing the automated connection between the cutting process and the conveying process.

[0066] The handling assembly 300 may include a movable frame 310 and a fixing member 320. The movable frame 310 is a frame structure component in the handling assembly 300 used to realize position movement. The movable frame 310 can move relative to the support platform 100 along a first direction. When the movable frame 310 moves along the first direction, it can drive the fixing member 320 to move closer to or further away from the stone slab 11 on the support platform 100, so that the fixing member 320 can move to the position of the stone slab 11 to perform the picking operation, and after the picking is completed, remove the stone slab 11 from the support area.

[0067] For example, the movable frame 310 can be disposed on the outside of the mounting bracket 210 of the cutting assembly 200, that is, on the side of the mounting bracket 210 away from the bearing area, so that the conveying assembly 300 and the cutting assembly 200 are arranged side by side in space. The movable frame 310 can be connected to the bearing platform 100 via a guide rail disposed on the bearing platform 100, or it can be disposed on a travel track independent of the bearing platform 100. The movement drive of the movable frame 310 can be a motor drive, and the movement along the first direction can be achieved through gear rack or lead screw transmission.

[0068] The fixing member 320 is movably disposed on the movable frame 310 along a third direction to adjust the height position of the fixing member 320. The fixing member 320 is an actuating component in the handling assembly 300 that directly contacts and picks up the stone slab 11, and is used to fix and support the stone slab 11 during handling.

[0069] The fixture 320 is movable along a third direction, allowing it to move up and down relative to the moving frame 310 in the height direction. This enables flexible adjustment based on the height of the stone slab 11 and the height of the cutting assembly 200, adapting to different height requirements at different stages of the operation. The fixture 320 can pass over the cutting assembly 200 and perform retrieval operations on the stone slab 11 cut from the stone 10.

[0070] The fastener 320 can pass over the cutting assembly 200 and perform a pick-up operation on the stone slab 11 formed by cutting the stone 10.

[0071] "Crossing over" means that during the movement of the fixing member 320 in the first direction, its movement path is higher than the highest point of the cutting assembly 200 in the third direction, so that the fixing member 320 and the stone slab 11 it carries can pass over the cutting assembly 200 without contacting or colliding with the cutting assembly 200.

[0072] The meaning of "crossing" has two aspects: First, in terms of spatial position, there is a clear vertical layering relationship between the fixing component 320 and the cutting component 200 in the height direction, with the lowest point of the fixing component 320 and its associated structure being higher than the highest point of the cutting component 200; Second, in terms of movement sequence, the fixing component 320 reaches a height higher than the cutting component 200 before entering the area where the cutting component 200 is located, and only decreases in height after completely leaving the area where the cutting component 200 is located, thus maintaining a safe height distance throughout the entire passage process.

[0073] The traversing movement allows the transport component 300 and the cutting component 200 to avoid each other in the height dimension. The fixing component 320 can start moving towards the support platform 100 without waiting for the cutting component 200 to completely exit the area near the support platform 100. The cutting component 200 also does not need to make way for the transport component 300 in the horizontal direction. The actions of the two components can remain independent or partially overlap in time, reducing the waiting time between processes.

[0074] "Removal" refers to the process by which the fixing member 320, after moving to the position of the stone slab 11, secures the stone slab 11 and allows it to move together with the fixing member 320. Removal involves two stages: the first stage is the establishment of a connection between the fixing member 320 and the stone slab 11, for example, by means of adsorption, clamping, or support, enabling the fixing member 320 to apply a holding force to the stone slab 11; the second stage is the fixing member 320 moving the stone slab 11 away from its original position, causing the stone slab 11 to detach from the main body of the stone 10 or from the support area of ​​the support platform 100.

[0075] The execution of the picking operation requires the fastener 320 and the stone slab 11 to be precisely aligned in position, and the force applied by the fastener 320 to the stone slab 11 when picking it up must be matched with the weight, surface condition and posture of the stone slab 11 to ensure that the stone slab 11 does not slip, deflect or get damaged during the picking process.

[0076] The crossing and retrieval are coordinated spatially and temporally. Before the fixing member 320 moves towards the support platform 100 to perform the retrieval operation, the fixing member 320 first rises to a second height, making itself higher than the cutting component 200. Then, it moves across the cutting component 200 along the first direction to the location of the stone slab 11, and then retrieves it. After retrieval, the fixing member 320 remains at a height higher than the cutting component 200, carrying the stone slab 11 across the cutting component 200 again, moving away from the support platform 100 along the first direction. The crossing provides a safe spatial passage for movement before and after retrieval. Retrieval is the core operation between the two crossings. Together, they constitute the complete sequence of actions by which the fixing member 320 completes the unloading of the stone slab 11 in the presence of the cutting component 200.

[0077] For example, the fixing member 320 can be moved along a third direction by a lifting mechanism disposed on the movable frame 310. The lifting mechanism may include a lifting frame and a lifting drive member. The lifting frame is slidably connected to the movable frame 310, the fixing member 320 is mounted on the lifting frame, and the lifting drive member drives the lifting frame to move up and down along a third direction.

[0078] The lifting drive component can be in the form of a cylinder, hydraulic cylinder, electric push rod, or screw jack. The fixing component 320 may include one or more pick-and-place parts 321, which are used to directly contact the surface of the stone slab 11 and fix it. The pick-and-place part 321 can be a vacuum suction cup, adsorbing onto the surface of the stone slab 11 through negative pressure. The pick-and-place part 321 can also be a gripper structure, fixing the stone slab 11 by clamping. The pick-and-place part 321 can also be an electromagnetic chuck, suitable for stone slabs 11 with ferromagnetic surfaces. The fixing component 320 may also have a rotation function, enabling it to flip the stone slab 11 from a vertical position to a horizontal position after it is picked up, facilitating its horizontal placement on the conveying device.

[0079] The first direction, the second direction, and the third direction can be mutually perpendicular. The three directions form a spatial orthogonal coordinate system, where the first direction can be the direction in which the cutting component 200 and the conveying component 300 move closer to or further away from the support platform 100, the second direction can be the direction in which the cutting component 220 moves laterally along the mounting bracket 210, and the third direction can be the height direction.

[0080] The vertical arrangement in three directions ensures that the lateral movement of the cutting component 220, the longitudinal movement of the cutting assembly 200 and the conveying assembly 300, and the vertical movement of the fixing component 320 are independent of each other and do not interfere with each other, thereby achieving precise control of each moving part and orderly coordination in space.

[0081] For example, the first direction may correspond to the horizontal longitudinal direction of the support platform 100, the second direction to the horizontal transverse direction of the support platform 100, and the third direction to the vertical direction. The cutting component 200 moves along the first direction to adjust the cutting depth or retraction, the cutting element 220 moves along the second direction to cover the cutting width of the stone 10, the conveying component 300 moves along the first direction to enter and exit the support area, and the fixing element 320 moves along the third direction to adjust the picking height and achieve crossing. The movement in the three directions can be performed independently or in coordination according to a preset timing and logic.

[0082] The support platform 100 provides stable support for the stone 10. The bracket 210 in the cutting assembly 200 can move along the first direction, and the cutting component 220 can move along the second direction, realizing multi-dimensional cutting and processing of the stone 10. The moving frame 310 in the handling assembly 300 can move along the first direction, and the fixing component 320 can move along the third direction to adjust its height and position, and cross over the cutting assembly 200 to perform the picking operation. The first direction, the second direction, and the third direction are mutually perpendicular to each other to form a spatial orthogonal coordinate system, so that the cutting and processing and handling and unloading are carried out in a layered and orderly manner in space. The fixing component 320 can pass safely over the cutting assembly 200, avoiding structural interference between the handling assembly 300 and the cutting assembly 200, and improving the work efficiency and operational safety of the stone slab 11 unloading process.

[0083] As a specific embodiment of this application, the third direction can be parallel to the height direction. The movable arrangement of the fixing member 320 along the third direction allows the fixing member 320 to move up and down relative to the moving frame 310 in the height direction, thereby changing its own height position according to the operation requirements to adapt to the different height requirements of different operation stages such as picking up the stone slab 11, crossing the cutting component 200, and placing the stone slab 11.

[0084] The fastener 320 can have a first height and a second height in the third direction. The first height and the second height are two different working positions of the fastener 320 in the height direction, corresponding to the height state of the fastener 320 when performing the operation of placing the stone slab 11 and the operation of crossing the cutting assembly 200, respectively.

[0085] By switching between the first height and the second height, the fastener 320 can achieve height conversion between the placement station and the crossing station, thereby meeting the spatial position requirements of the fastener 320 for different processes.

[0086] When the fastener 320 is at the first height, the height of the fastener 320 can be lower than the height of the cutting assembly 200 so that the slab 11 can be placed on the conveying device.

[0087] The first height is the working height of the fixing member 320 when it performs the stone slab 11 placement operation. When the fixing member 320 descends to the first height, the fixing member 320 as a whole is located below the cutting assembly 200 in the height direction. At this time, the stone slab 11 picked up by the fixing member 320 can approach the placement plane of the conveying device, which makes it easy to release the stone slab 11 smoothly onto the conveying device.

[0088] Setting the height of the fastener 320 at the first height to be lower than the height of the cutting assembly 200 can, on the one hand, ensure that the stone slab 11 is not restricted by the space of the cutting assembly 200 during placement, and on the other hand, ensure that the fastener 320 has sufficient descent stroke when placing the stone slab 11, so that the stone slab 11 can be placed on the receiving surface of the conveying device, thereby reducing the impact or damage to the stone slab 11 caused by excessive drop.

[0089] For example, the specific value of the first height can be set according to the height position of the conveying device. The conveying device can be set on the side of the support platform 100 away from the cutting component 200, or it can be set on the side of the support platform 100. The first height can be slightly higher than the conveying surface of the conveying device, so that the gap between the stone slab 11 and the conveying surface is small when the fixing member 320 releases the stone slab 11, and the stone slab 11 can be placed smoothly. The first height can also be adjusted according to the thickness of the stone slab 11. For thicker stone slabs 11, the first height can be appropriately increased to avoid the stone slab 11 being squeezed by the conveying device during placement. The process of the fixing member 320 descending from the second height to the first height can be realized by a lifting mechanism. The descent speed can be set to be fast at first and then slow down, reducing the speed when approaching the first height to improve placement accuracy.

[0090] When several stone slabs 11 have been stacked on the conveying device, as the stacking height of the stone slabs 11 increases, the first height of the fixing member 320 can be adaptively increased accordingly, so that the position where the fixing member 320 releases the stone slabs 11 and the current top surface of the stack are always kept at a suitable distance, so as to avoid the stone slabs 11 falling from too high and causing collisions, and also to avoid the fixing member 320 interfering with the stacked stone slabs 11.

[0091] When the fixing member 320 is at the second height, the height of the fixing member 320 can be higher than the height of the cutting assembly 200, so that the fixing member 320 crosses over the cutting assembly 200 during the process of moving towards the support platform 100 and during the process of carrying the stone slab 11 away from the support platform 100.

[0092] The second height is the working height of the fixing member 320 when it performs the operation of crossing the cutting assembly 200. When the fixing member 320 rises to the second height, the fixing member 320 as a whole is above the cutting assembly 200 in the height direction. At this time, the moving path of the fixing member 320 and the stone slab 11 picked up by the fixing member 320 is completely above the highest point of the cutting assembly 200 during the movement along the first direction, and will not come into contact with the cutting assembly 200.

[0093] The fastener 320 is at a second height as it moves toward the support platform 100 to approach the stone slab 11. This ensures that the fastener 320 can safely pass over the cutting assembly 200 before the stone slab 11 is removed, preventing the fastener 320 from colliding with the cutting assembly 200 when unloaded. The fastener 320 maintains a second height while carrying the stone slab 11 away from the support platform 100 after it is removed. This ensures that the stone slab 11 maintains sufficient clearance from the cutting assembly 200 when crossing it, preventing the surface of the stone slab 11 from being scratched by the cutting assembly 200 or from colliding with the cutting assembly 200 and falling off.

[0094] For example, the specific value of the second height can be set according to the height of the highest point of the cutting assembly 200. The highest point of the cutting assembly 200 can be the upper edge of the cutting piece 220, the top of the mounting bracket 210, or the highest position of the pusher. The second height should be a certain distance higher than the highest point of the cutting assembly 200. This distance can serve as a safety clearance to compensate for height fluctuations or vibrations that may occur during movement, ensuring that the fixing piece 320 and the slab 11 never come into contact with the cutting assembly 200 when crossing it.

[0095] The process of the fixing component 320 rising from the first height to the second height can be completed before the moving frame 310 moves towards the support platform 100 in the first direction, or it can be done simultaneously during the movement of the moving frame 310 towards the support platform 100, in order to shorten the operation cycle time. After the fixing component 320 picks up the stone slab 11, it can rise to the second height and then move away from the support platform 100 in the first direction, or it can rise at the same time as picking up the stone slab 11.

[0096] By setting the third direction to be parallel to the height direction, and giving the fixing member 320 a first height and a second height in the third direction, the fixing member 320 is lower than the cutting assembly 200 when it is at the first height, which facilitates the placement of the stone slab 11 on the conveying device; the fixing member 320 is higher than the cutting assembly 200 when it is at the second height, which facilitates crossing over the cutting assembly 200 during the movement towards the support platform 100 and the carrying of the stone slab 11 away from the support platform 100. This dual-height setting allows the fixing member 320 to select an appropriate working height according to the different operational requirements of placement and crossing. When crossing the cutting assembly 200, it can pass safely from above, and when placing the stone slab 11, it can lower its height to approach the conveying device. This achieves spatial coordination between the handling process and the cutting assembly 200 in the height direction, reduces the risk of structural interference, and improves the continuity and operational efficiency of the stone slab 11 unloading and placement process.

[0097] As a specific embodiment of this application, before the fixing member 320 approaches the support platform 100 to pick up the stone slab 11 in the first direction, it can rise from the first height position to the second height position so that the fixing member 320 is higher than the cutting component 200 in the third direction.

[0098] Before the fixing member 320 moves toward the support platform 100 and performs the picking operation, the fixing member 320 first completes the rising action from the first height to the second height. The first height can be the height at which the fixing member 320 was when it placed the stone slab 11 in the previous work cycle, or it can be the initial height of the fixing member 320 in the standby state.

[0099] By raising the fastener 320 to a second height in advance, the fastener 320 is positioned above the cutting assembly 200 when it begins to move toward the support platform 100. As a result, during the subsequent process of moving toward the support platform 100 in the first direction, the overall height of the fastener 320 remains above the highest point of the cutting assembly 200, and its movement path is above the cutting assembly 200, so it will not come into any contact or interfere with the cutting assembly 200.

[0100] For example, the action of raising the fixing member 320 from the first height to the second height can be completed before the moving frame 310 moves in the first direction, or it can be performed synchronously with the movement of the moving frame 310 in the first direction. When the raising action is performed synchronously with the horizontal movement, the fixing member 320 gradually rises during the horizontal movement and reaches the second height before reaching above the cutting assembly 200, thereby shortening the overall operation time.

[0101] The upward movement can be driven by a lifting mechanism mounted on the movable frame 310. The lifting mechanism moves the fixed component 320 upward in a third direction to a second height position. The specific value of the second height can be set with reference to the highest point of the cutting component 200, and a safety gap can be added to ensure that the fixed component 320 has sufficient height margin during the crossing process.

[0102] After the stone slab 11 is removed, the fastener 320 can hold the stone slab 11 at a second height, carrying it away from the support platform 100 in a first direction, so as to cross over the cutting assembly 200.

[0103] After the fixing member 320 completes the removal of the stone slab 11, the fixing member 320 remains at the second height position, carrying the removed stone slab 11 along the first direction away from the support platform 100. Since both the fixing member 320 and the stone slab 11 are at the second height, which is higher than the height of the cutting assembly 200, the fixing member 320 and the stone slab 11 can pass directly over the cutting assembly 200 during the movement away from the support platform 100 without scraping or colliding between the stone slab 11 and the cutting assembly 200. When the stone slab 11 crosses the cutting assembly 200, it is in a state of being firmly held by the fixing member 320, and its bottom is higher than the highest point of the cutting assembly 200 in the third direction, thus realizing the safe removal action of the stone slab 11 across the cutting assembly 200.

[0104] For example, while the fixing member 320 is holding the stone slab 11 at the second height after it has been picked up, the fixing member 320 continues to exert a picking force on the stone slab 11, ensuring that the stone slab 11 will not loosen or fall off due to vibration or inertia when crossing the cutting assembly 200. After the fixing member 320 carries the stone slab 11 across the cutting assembly 200, it can be lowered from the second height to the first height or other suitable height position as needed for subsequent placement of the stone slab 11.

[0105] During the process of the fixing member 320 picking up the stone slab 11 and holding it at the second height, the moving frame 310 can be set to a constant speed along the first direction, or the speed can be adjusted in segments according to different stages of crossing the cutting component 200. For example, the speed can be appropriately reduced when approaching directly above the cutting component 200, and then restored to normal speed after passing through.

[0106] Before retrieving the stone slab 11 from the support platform 100, the fixing member 320 is pre-raised from a first height to a second height, ensuring that the fixing member 320 remains above the cutting assembly 200 throughout its movement towards the support platform 100. This prevents interference between the fixing member 320 and the cutting assembly 200 when unloaded. After retrieving the stone slab 11, the fixing member 320 maintains the second height, carrying the stone slab 11 away from the support platform 100. This ensures a safe height distance between the stone slab 11 and the cutting assembly 200 when crossing them, preventing scratches or collisions. This coordination of height switching and action timing allows the fixing member 320 to pass above the cutting assembly 200 in both the initial and subsequent movement phases before and after retrieving the stone slab 11, achieving complete vertical avoidance between the transport path and the cutting area, thus improving the safety and continuity of the stone slab 11 unloading process.

[0107] As a specific embodiment of this application, after the fixing member 320 carries the picked-up stone slab 11 across the cutting assembly 200, it can descend from the second height to the first height to place the picked-up stone slab 11 on the conveying device.

[0108] After the fastener 320, carrying the stone slab 11, moves along the first direction and passes completely over the area above the cutting assembly 200, the fastener 320 begins to descend from the second height position and transition to the first height position.

[0109] This descent occurs after the slab 11 has safely passed the cutting assembly 200 and there is no longer any risk of spatial interference with it. During the descent, the slab 11 maintains a sufficient distance from the cutting assembly 200 in the third direction, preventing contact with the cutting assembly 200 as the height decreases. After descending to the first height, the fixing member 320 releases the slab 11 onto the conveying device, completing the placement of the slab 11.

[0110] For example, the timing of the descent of the fixing member 320 from the second height to the first height can be controlled by a position sensor or a limit switch. When the moving frame 310 moves along the first direction to the preset crossing completion position, the control system receives the position signal and drives the lifting mechanism to move the fixing member 320 downward along the third direction.

[0111] The descent can be synchronized with the movement of the mobile frame 310 towards the conveyor in the first direction. That is, the fixing member 320 gradually decreases in height while moving horizontally, thus shortening the overall operation cycle time. Alternatively, the horizontal movement can be completed first, and the descent can be performed separately after the mobile frame 310 reaches above the conveyor, improving the accuracy of the placement. The descent speed can be set to be fast at first and then slow, decelerating when approaching the first height to ensure smooth movement of the stone slab 11 as it approaches the conveyor, reducing impact. When multiple stone slabs 11 are already stacked on the conveyor, the specific value of the first height can be adaptively increased, allowing the fixing member 320 to stop at an appropriate position above the current stacking height, without needing to descend to the initial first height position, thus adapting to the needs of continuous stacking operations.

[0112] By using the fixing component 320 to lower the stone slab 11 from the second height to the first height after it crosses the cutting assembly 200, the stone slab 11 is safely removed from the area where the cutting assembly 200 is located. Then, it gradually decreases in height to approach the conveying device, achieving a smooth transition between the crossing and placement phases. This descent action spatially avoids the cutting assembly 200, preventing the stone slab 11 from contacting it during the descent process. Functionally, it connects the crossing and placement operations, allowing the stone slab 11 to smoothly transition from the crossing height to the placement height, improving the continuity and efficiency of the unloading and placement process.

[0113] As a specific embodiment of this application, when the fixing member 320 picks up the stone slab 11, the cutting component 200 can move away from the support platform 100 in a first direction to form a picking space in the first direction.

[0114] During the stage when the fixing member 320 approaches the stone slab 11 and performs the picking action, the cutting component 200 moves synchronously or in advance along the first direction away from the support platform 100, thereby increasing the distance between the cutting component 200 and the stone slab 11 on the support platform 100 in the first direction, thus creating a space area between the cutting component 200 and the stone slab 11, which is the picking space.

[0115] The formation of the retrieval space allows the fixing member 320 to have a more ample operating range when approaching the stone slab 11, positioning and aligning the stone slab 11, and performing the retrieval action. The fixing member 320 and its associated structure will not interfere with the cutting component 200 during the operation, reducing the difficulty of positioning and retrieval of the fixing member 320.

[0116] For example, the movement of the cutting assembly 200 away from the support platform 100 along the first direction can be coordinated with the movement of the fixing member 320 towards the support platform 100 along the first direction. When the fixing member 320 begins to move towards the support platform 100, the cutting assembly 200 can simultaneously begin to retract in the opposite direction, and the two move towards each other, so that the retrieval space can be quickly formed.

[0117] The clearance distance of the cutting component 200 can be set according to the structural dimensions of the fixing member 320, the thickness of the stone slab 11, and the front and rear operating space required for the fixing member 320 to pick up the stone slab 11. After clearance, the distance between the cutting component 200 and the stone slab 11 in the first direction can be greater than the maximum external dimension of the fixing member 320 in the first direction, so as to ensure that the fixing member 320 has sufficient safety margin when picking up the stone slab 11.

[0118] After the cutting component 200 has retracted, it can remain in the retracted position and wait until the fixing component 320 has finished picking up the stone slab 11 and carrying it away from the area above the support platform 100. Then, it returns to the working position along the first direction, ready to cut the next stone slab 11. The retraction and return actions of the cutting component 200 can be realized by a drive mechanism. The drive mechanism can be coordinated with the lifting mechanism of the fixing component 320 and the movement drive of the moving frame 310 to achieve orderly connection of various actions.

[0119] By moving the cutting assembly 200 away from the support platform 100 along the first direction when the fixing member 320 picks up the stone slab 11, a picking space is formed in the first direction, providing the fixing member 320 with an interference-free working area. The fixing member 320 can complete the positioning, alignment and picking of the stone slab 11 in the ample space, reducing the positioning difficulties and collision risks caused by the narrow space. Combined with the avoidance method of the fixing member 320 crossing over the cutting assembly 200, the smooth picking operation is ensured from both the height and horizontal dimensions, improving the reliability and work efficiency of the stone slab 11 unloading process.

[0120] As a specific embodiment of this application, the fastener 320 may include a pick-and-place portion 321 for fixing the stone slab 11.

[0121] The pick-and-place section 321 is a functional component of the fixing member 320 that directly contacts the stone slab 11 and applies a fixing force to the stone slab 11. It is used to pick up, hold, and release the stone slab 11 during transportation. The pick-and-place section 321 is located at the end of the fixing member 320. After the fixing member 320 moves to the position of the stone slab 11, it can adsorb, clamp, or fix the surface of the stone slab 11 in other ways, ensuring that the stone slab 11 maintains a stable relative positional relationship with the fixing member 320 during transportation, and preventing the stone slab 11 from loosening, slipping, or falling off during movement, crossing, or posture changes.

[0122] The pick-and-place unit 321 can rotate about an axis parallel to a second direction. The second direction is the direction of movement of the cutting piece 220, and the axis parallel to the second direction is a rotating shaft extending horizontally in the transverse direction. When the pick-and-place unit 321 rotates about this axis, the orientation of the pick-and-place unit 321 can switch between the first direction and the third direction. This rotational capability allows the pick-and-place unit 321 not only to fix the vertically placed stone slab 11 in an orientation facing the first direction, but also to change the orientation of the stone slab 11 from a vertical to a horizontal position by rotation, thereby meeting the requirements for changing the orientation of the stone slab 11 from the cutting station to the conveying device.

[0123] The rotation drive of the pick-and-place section 321 can be achieved by a drive component such as a rotary cylinder, a servo motor, or a swing hydraulic cylinder. The drive component can be located at the connecting joint between the fixed member 320 and the pick-and-place section 321.

[0124] When the pick-up and place section 321 rotates to the first posture, the pick-up and place section 321 can face the first direction to fix the vertical stone slab 11.

[0125] The first posture is the posture of the pick-and-place unit 321 when it picks up the vertically placed stone slab 11. In this posture, the working surface of the pick-and-place unit 321 faces the first direction, that is, the direction in which the stone slab 11 is located on the support platform 100. Since the stone slab 11 stands vertically on the main body of the stone 10 after cutting, and the normal direction of the surface of the stone slab 11 is parallel to the first direction, the posture of the pick-and-place unit 321 facing the first direction matches the surface direction of the stone slab 11, so that the pick-and-place unit 321 can approach the stone slab 11 directly facing the surface of the stone slab 11, achieving a larger area of ​​contact and reliable fixation.

[0126] After the pick-and-place unit 321 fixes the stone slab 11 in the first posture, the stone slab 11 can still maintain a vertical state during subsequent movement and crossing, which makes it easy to cross over the cutting component 200 in a vertical posture and reduce the projected size of the stone slab 11 in the height direction during the crossing process.

[0127] For example, in the first posture, the working surface of the pick-and-place part 321 can be perpendicular to the first direction, that is, the working surface of the pick-and-place part 321 is parallel to the surface of the stone slab 11. The pick-and-place part 321 can be a vacuum suction cup, with the suction surface of the vacuum suction cup facing the first direction. When the fixing member 320 drives the pick-and-place part 321 to approach the stone slab 11 along the first direction, the suction surface can be directly attached to the surface of the stone slab 11, and fixation is achieved through negative pressure suction.

[0128] The pick-and-place section 321 can also adopt a gripper structure, with the opening of the gripper facing the first direction. When the pick-and-place section 321 approaches the stone slab 11, the gripper clamps the stone slab 11 from the side or the top and bottom ends. In the first posture, the pick-and-place section 321 can also have a fine-tuning capability along the first direction. For example, the extension amount of the pick-and-place section 321 along the first direction can be slightly adjusted by means of an elastic element or a micro-motion mechanism to accommodate possible positional deviations of the stone slab 11 in the first direction, thereby improving the accuracy and reliability of the fixation.

[0129] When the pick-up and place section 321 is rotated to the second posture, the pick-up and place section 321 can face downwards so that the stone slab 11 can be placed horizontally.

[0130] The second posture is the posture in which the pick-and-place unit 321 places the stone slab 11 horizontally on the conveying device. In this posture, the working surface of the pick-and-place unit 321 faces downward, i.e., towards the receiving surface of the conveying device. During the process of the pick-and-place unit 321 rotating from the first posture to the second posture, the stone slab 11 being picked up rotates synchronously, changing from a vertical posture to a horizontal posture. When the pick-and-place unit 321 rotates to the second posture, the surface of the stone slab 11 is horizontal, and the lower surface of the stone slab 11 faces the conveying device. At this time, the fixing member 320 descends along a third direction, so that the stone slab 11 can be placed smoothly on the conveying surface of the conveying device, completing the horizontal placement of the stone slab 11.

[0131] For example, the rotation angle of the pick-and-place unit 321 from the first posture to the second posture can be ninety degrees. The rotation process can be completed after the fixing member 320 carries the stone slab 11 across the cutting assembly 200 and before it reaches the top of the conveying device, or it can be performed after the fixing member 320 reaches the top of the conveying device. In the second posture, the working surface of the pick-and-place unit 321 can be parallel to the horizontal plane, that is, the adsorption surface or clamping surface of the pick-and-place unit 321 faces directly downward, so that the stone slab 11 can be released in a horizontal posture and placed smoothly. After releasing the stone slab 11 in the second posture, the pick-and-place unit 321 can rotate back to the first posture to prepare for the next round of picking operations. The rotation direction of the pick-and-place unit 321 can be set to unidirectional continuous rotation or reciprocating swing, which can be selected according to the work rhythm and structural layout.

[0132] A pick-and-place section 321, rotatable about an axis parallel to the second direction, is provided by the fixing member 320. When the pick-and-place section 321 rotates to the first position, it faces the first direction and can match the vertical surface of the stone slab 11, enabling reliable picking up of the stone slab 11. When the pick-and-place section 321 rotates to the second position, it faces downward, which can change the stone slab 11 from a vertical position to a horizontal position, making it easier to place the stone slab 11 horizontally on the conveying device. The rotation function of the pick-and-place section 321 allows the fixing member 320 to integrate both picking and position conversion functions in a single actuating component. The stone slab 11 does not need to be adjusted in position through an additional flipping mechanism during transportation, simplifying the transportation process and improving the continuity and efficiency of picking up and placing the stone slab 11.

[0133] As a specific embodiment of this application, after the pick-up and place unit 321 picks up the stone slab 11, it can first rotate around the axis above the support platform 100 from the first posture to the second posture, so as to change the stone slab 11 from the vertical state to the horizontal state.

[0134] After the pick-up and drop-down unit 321 completes the picking up of the stone slab 11, it does not immediately move away from the support platform 100 in the first direction. Instead, it first performs a posture flipping action in the space above the support platform 100. After the stone slab 11 is completely changed from a vertical state to a horizontal state, it begins to move across the cutting component 200 in the first direction.

[0135] The flipping process is completed above the support platform 100. This means that after the stone slab 11 is taken out by the fixing member 320, the moving frame 310 and the fixing member 320 are temporarily held near the support platform 100. The picking and placing part 321 rotates around an axis parallel to the second direction, causing the stone slab 11 to rotate from a vertical position to a horizontal position. This flipping process is completed in the space above the support platform 100.

[0136] The space above the support platform 100 refers to the space above the support area of ​​the support platform 100 and the area between the cutting component 200 and the support area. This space has sufficient clearance in the vertical direction to accommodate the maximum external dimensions required for the stone slab 11 to rotate from a vertical to a horizontal state. The rotation is completed within this space, and the stone slab 11 will not be interfered with by the cutting component 200 or other structures during the rotation. After the rotation is completed, the stone slab 11 is held horizontally by the fixing member 320, preparing it for subsequent crossing of the cutting component 200.

[0137] After the flip is completed, move away from the support platform 100 along the first direction and cross over the cutting component 200.

[0138] After the stone slab 11 has been flipped to a horizontal position, the moving frame 310 drives the fixing member 320 and the stone slab 11 to move away from the support platform 100 along the first direction. Since the stone slab 11 is in a horizontal position at this time, the height of the stone slab 11 in the third direction is its thickness, which is significantly reduced compared to its height in the vertical position. When the fixing member 320 carries the horizontally positioned stone slab 11 along the first direction, the stone slab 11 passes over the cutting assembly 200, and the bottom surface of the stone slab 11 is higher than the highest point of the cutting assembly 200 in the third direction, thus achieving a crossing over the cutting assembly 200.

[0139] For example, the flipping action of the pick-and-place unit 321 above the support platform 100 around the axis can rotate by 90 degrees, changing the stone slab 11 from a vertical state with its surface parallel to the first direction to a horizontal state with its surface parallel to the horizontal plane. The flipping speed can be adjusted according to the weight and size of the stone slab 11, and the rotation speed can be appropriately reduced during the start and stop phases to reduce inertial impact. After the flipping is completed, the fixing member 320 can be appropriately adjusted in height along the third direction to maintain a safe distance between the stone slab 11 and the cutting assembly 200 when it subsequently crosses the cutting assembly 200. After the pick-and-place unit 321 completes the flipping above the support platform 100, the moving frame 310 starts moving along the first direction. The movement can be carried out at a constant speed or at different speeds depending on the different stages of crossing the cutting assembly 200.

[0140] After the stone slab 11 is picked up by the pick-up and put-down unit 321, it first rotates from a first posture to a second posture around the axis above the support platform 100, changing the stone slab 11 from a vertical state to a horizontal state. After the flipping is completed, it moves away from the support platform 100 along the first direction and crosses over the cutting component 200. This allows the stone slab 11 to be carried out step by step in space during the posture transformation stage and the crossing movement stage. The flipping action is completed in a safe space above the support platform 100, avoiding the risk of shaking or interference with the cutting component 200 that may occur when the stone slab 11 is flipped during the movement. At the same time, the space required in the height direction when the stone slab 11 crosses the cutting component 200 in a horizontal posture is smaller, which makes it easier to maintain a safe distance from the cutting component 200 and improves the stability and safety of the stone slab 11 unloading process.

[0141] As a specific embodiment of this application, after the pick-up and place unit 321 picks up the stone slab 11, during the process of moving away from the support platform 100 in the first direction, it rotates around the axis from the first posture to the second posture, which can change the stone slab 11 from a vertical state to a horizontal state.

[0142] After the pick-up and place unit 321 completes the picking up of the stone slab 11, the moving frame 310 then moves the fixing member 320 and the stone slab 11 away from the support platform 100 along the first direction. While moving horizontally, the pick-up and place unit 321 rotates around an axis parallel to the second direction. As the stone slab 11 moves horizontally with the fixing member 320, it simultaneously completes the posture transformation from a vertical state to a horizontal state.

[0143] The flipping motion during the movement away from the support platform 100 along the first direction refers to the overlapping execution of the flipping action and the horizontal movement action in time. After the pick-up and place unit 321 picks up the stone slab 11 in the first posture, the stone slab 11 is initially in a vertical state. As the moving frame 310 begins to move along the first direction, the pick-up and place unit 321 simultaneously initiates rotation around the axis. While the stone slab 11 is undergoing horizontal displacement, it gradually changes its posture, gradually tilting from a vertical state and finally transitioning to a horizontal state. In this process, the movement of the stone slab 11 is a composite motion of horizontal translation and rotation around the axis.

[0144] For example, the flipping speed of the pick-and-place unit 321 can be matched with the moving speed of the moving frame 310 along the first direction, so that the stone slab 11 remains stable during the posture transformation. When the moving frame 310 moves along the first direction to the area above the cutting assembly 200, the stone slab 11 has completed a partial flipping, and the size occupied by the stone slab 11 in the height direction gradually decreases, which helps the stone slab 11 to pass safely over the cutting assembly 200.

[0145] The flipping action of the pick-and-place unit 321 can be completed before the moving frame 310 passes over the cutting assembly 200, so that the stone slab 11 is already in a horizontal or nearly horizontal state when it reaches directly above the cutting assembly 200, thus crossing the cutting assembly 200 with a smaller vertical dimension. Alternatively, the flipping can continue throughout the crossing of the cutting assembly 200, with the stone slab 11 in an inclined state when passing over the cutting assembly 200, and flipped to a completely horizontal state after passing.

[0146] After the flipping is completed, the stone slab 11 is held horizontally by the fixing member 320 and continues to move with the moving frame 310 to the top of the conveying device. Then, the fixing member 320 descends along the third direction to place the stone slab 11 on the conveying device.

[0147] By synchronizing the flipping action with the movement along the first direction after picking up the stone slab 11, the stone slab 11 completes its posture change while moving horizontally, reducing the extra time consumption caused by the step-by-step operation of flipping first and then moving, and improving the overall cycle time of the unloading operation. At the same time, the stone slab 11 gradually changes from vertical to horizontal during the movement. When passing over the cutting component 200, the projection size of the stone slab 11 in the height direction can be reduced according to the flipping progress, which is conducive to the stone slab 11 crossing the cutting component 200 in a more compact spatial posture, taking into account both the needs of action efficiency and space avoidance.

[0148] As a specific embodiment of this application, during the process of the pick-and-place unit 321 rotating from the first posture to the second posture, the picked-up stone slab 11 can be higher than the cutting component 200 in the third direction.

[0149] Throughout the entire process of the pick-and-place unit 321 rotating the stone slab 11 from a vertical to a horizontal state, the lowest point of the stone slab 11 in the third direction is always higher than the highest point of the cutting component 200. That is, the stone slab 11 and the cutting component 200 always maintain a distance in the height direction and will not come into contact or collide due to the change of posture.

[0150] When the stone slab 11 begins to rotate around its axis from a vertical position, the position of its bottom edge in the third direction changes with the rotation angle. By pre-raising the pick-and-place unit 321 and the stone slab 11 to a suitable height before flipping, or by adjusting the height of the pick-and-place unit 321 in real time during the flipping process, it can be ensured that the lowest part of the stone slab 11 is always above the cutting component 200 when rotated to any angle. In this way, the stone slab 11 does not need to interrupt the flipping action to avoid the cutting component 200 during the posture change, and the flipping action can be completed continuously and smoothly.

[0151] For example, before starting the flipping, the pick-and-place unit 321 can first rise to a second height or higher along a third direction, so that the bottom of the stone slab 11 is already higher than the cutting component 200 when it is in a vertical state. During the subsequent flipping process, the height of the rotation axis of the pick-and-place unit 321 remains unchanged or continues to rise, and the stone slab 11 rotates around the axis, with the lowest point of its bottom edge always higher than the highest point of the cutting component 200 in the third direction. The pick-and-place unit 321 can also adopt a compound motion of flipping and rising simultaneously. According to the shape contour of the stone slab 11 at different flipping angles, the position of the pick-and-place unit 321 in the third direction is dynamically adjusted so that the stone slab 11 is always above the cutting component 200. After the flipping action is completed, the stone slab 11 is in a horizontal position. At this time, the overall position of the stone slab 11 in the third direction is still higher than the cutting component 200, preparing for subsequent crossing of the cutting component 200 along the first direction.

[0152] During the rotation from the first posture to the second posture by the pick-up and place unit 321, the picked-up stone slab 11 is always higher than the cutting component 200 in the third direction. Throughout the entire dynamic process of posture transformation, the stone slab 11 and the cutting component 200 maintain a safe height distance. This avoids the bottom of the stone slab 11 from falling and scraping or colliding with the cutting component 200 due to the flipping action. It achieves coordinated cooperation between posture transformation and space avoidance, and improves the safety and continuity of the stone slab 11 handling process.

[0153] As a specific embodiment of this application, when the fastener 320 crosses the cutting assembly 200, the fastener 320 may have a safe distance between itself and the cutting assembly 200 in the third direction.

[0154] The safety clearance refers to the difference in distance between the lowest point of the fixing member 320 and the highest point of the cutting assembly 200 in a third direction when the fixing member 320 passes over the cutting assembly 200. The safety clearance is set to provide sufficient space for the fixing member 320 and the stone slab 11 it carries during the crossing process, to cope with possible height fluctuations, vibrations or positional deviations during the movement, and to ensure that the fixing member 320 and the stone slab 11 do not come into contact with the cutting assembly 200 when passing over it.

[0155] The safety clearance can be greater than the thickness of slab 11. The thickness of slab 11 refers to the dimension of slab 11 in the direction perpendicular to the slab surface.

[0156] When the stone slab 11 is carried horizontally across the cutting assembly 200 by the fixing member 320, the spatial dimension occupied by the stone slab 11 in the third direction is mainly reflected in its thickness. Setting the safety gap to be greater than the thickness of the stone slab 11 means that even if the stone slab 11 is in a horizontal state during the crossing, the distance between its lower surface and the highest point of the cutting assembly 200 is greater than the thickness of the stone slab 11 itself, thereby ensuring that the stone slab 11 can safely pass over the cutting assembly 200 in a horizontal state. Under this condition, even if the stone slab 11 experiences slight height fluctuations during movement, there is still sufficient buffer space between the stone slab 11 and the cutting assembly 200.

[0157] Alternatively, the safety clearance can be greater than half the width of the stone slab 11. The width of the stone slab 11 refers to the dimension of the stone slab 11 in the first direction when it is placed vertically, that is, the horizontal span of the surface of the stone slab 11. When the stone slab 11 has not completed its posture change during the crossing process and is still in a vertical or tilted state, the edge of the stone slab 11 may extend downward during the rotation of the pick-and-place unit 321 around an axis parallel to the second direction.

[0158] In this case, the lowest point of the slab 11 in the third direction may not be consistent with the lowest point of the fastener 320, and a part of the slab 11 may be closer to the cutting assembly 200. Setting the safety gap to more than half the width of the slab 11 ensures that during the process of flipping the slab 11 from a vertical to a horizontal state, no part of the slab 11 will fall below the highest point of the cutting assembly 200 due to rotation, providing sufficient height space for the slab 11 during the attitude conversion process.

[0159] For example, the specific value of the safety clearance can be set by considering both the thickness and width of the slab 11. When the slab 11 always crosses the cutting component 200 in a horizontal position, the safety clearance can be greater than the thickness of the slab 11. When the slab 11 flips during the crossing process, the safety clearance can be greater than half the width of the slab 11 to ensure that the lowest part of the slab 11 is always higher than the cutting component 200 during the flipping process. The safety clearance can also simultaneously meet the conditions of being greater than both the thickness and half the width of the slab 11 to accommodate the needs of different crossing methods. Furthermore, a certain safety margin coefficient can be added to the value of the safety clearance to cope with factors such as mechanical vibration, control errors, or dimensional deviations of the slab 11 that may occur during actual operation.

[0160] When crossing the cutting assembly 200, a safety distance is set between the fixing member 320 and the cutting assembly 200 in a third-direction upward direction. The safety distance is set to be greater than the thickness of the stone slab 11 or greater than half the width of the stone slab 11. This ensures that the fixing member 320 and the stone slab 11 always maintain sufficient space between themselves and the cutting assembly 200 during the crossing process, avoiding scratches or collisions caused by insufficient height. This ensures the safety and reliability of the crossing action and provides suitable space conditions for the crossing of the stone slab 11 in different postures.

[0161] In summary, the working process of the intelligent automatic unloading device can be divided into a cutting stage and an unloading stage, which are carried out in coordination on the support platform 100.

[0162] During the cutting stage, the stone 10 to be cut is placed on the support area of ​​the support platform 100. The mounting bracket 210 of the cutting assembly 200 moves along a first direction toward the support platform 100, causing the cutting component 220 to approach the stone 10. The cutting component 220 moves laterally along a second direction on the mounting bracket 210 to cut the stone 10, forming a cutting slit between the stone slab 11 and the main body of the stone 10. After cutting, the stone slab 11 stands vertically on the main body of the stone 10, and the cutting assembly 200 can be appropriately retracted along the first direction or remain in its original position as needed.

[0163] Entering the unloading stage, the handling component 300 begins to perform the picking and transferring of slab 11.

[0164] First, the fastener 320 rises from a first height position to a second height position along a third direction. The first height can be the height of the fastener 320 after placing the stone slab 11 in the previous work cycle, or it can be the initial height in the standby state. After the fastener 320 rises to the second height, its overall position is higher than the highest point of the cutting assembly 200 along a third direction, preparing it for subsequent crossing over the cutting assembly 200.

[0165] Subsequently, the moving frame 310 moves along the first direction toward the support platform 100, moving the fixing member 320 along with it. Since the fixing member 320 is already at the second height, it passes above the cutting assembly 200 throughout its movement toward the support platform 100, without contacting it. During its movement toward the support platform 100, the fixing member 320 and the cutting assembly 200 maintain a safe distance in the third direction. This safe distance can be greater than the thickness of the stone slab 11 or greater than half the width of the stone slab 11, ensuring sufficient height margin during the crossing process.

[0166] When the fixing member 320 approaches the stone slab 11 to perform the picking operation, the cutting assembly 200 can move away from the support platform 100 along the first direction to create a clearance space in the first direction, forming a picking space. The formation of the picking space allows the fixing member 320 to have a more ample operating range when approaching the stone slab 11 and positioning and aligning it, and the fixing member 320 and its associated structure will not interfere with the cutting assembly 200 during the operation.

[0167] After the fixing member 320 moves to the position of the stone slab 11, the pick-and-place part 321 is in a first posture, that is, the pick-and-place part 321 faces the first direction, which matches the surface direction of the vertically placed stone slab 11. The pick-and-place part 321 performs a pick-and-place operation on the stone slab 11, establishing a reliable connection with the stone slab 11 through adsorption, clamping or other fixing methods, so that the stone slab 11 is firmly held on the pick-and-place part 321. After the pick-and-place is completed, the stone slab 11 remains in a vertical state.

[0168] Next, depending on the different action strategies, the pose transformation of the slab 11 and the crossing of the cutting component 200 can be performed in two ways.

[0169] In one method, after picking up the stone slab 11, the pick-up and place unit 321 first rotates from a first posture to a second posture above the support platform 100 around an axis parallel to the second direction. During the rotation, the pick-up and place unit 321 gradually changes the stone slab 11 from a vertical state to a horizontal state. The flipping action is completed in the space above the support platform 100, which has sufficient clearance in the height direction to accommodate the maximum external dimensions of the stone slab 11 during the rotation. After the flipping is completed, the stone slab 11 is held in a horizontal posture by the pick-up and place unit 321. Subsequently, the moving frame 310 moves away from the support platform 100 along the first direction, carrying the horizontally positioned stone slab 11 over the cutting assembly 200. Since the stone slab 11 is now in a horizontal posture, its height dimension in the third direction is reduced, facilitating safe passage over the cutting assembly 200.

[0170] In another method, after the pick-up and place unit 321 picks up the stone slab 11, the moving frame 310 immediately moves away from the support platform 100 along the first direction. During the movement, the pick-up and place unit 321 simultaneously rotates around the axis from the first posture to the second posture, and the posture change of the stone slab 11 and the horizontal movement occur simultaneously. During the movement and flipping process, the stone slab 11 is always higher than the cutting component 200 in the third direction, ensuring that the stone slab 11 will not come into contact with the cutting component 200 at any stage of posture change. After the moving frame 310 passes through the area above the cutting component 200, the stone slab 11 has completed the transformation from a vertical state to a horizontal state.

[0171] Regardless of the method used, when the fixing member 320 carries the stone slab 11 across the cutting assembly 200, the fixing member 320 and the stone slab 11 maintain a safe distance from the cutting assembly 200 in the third direction, ensuring the safety of the crossing process.

[0172] After the fixing member 320 carries the stone slab 11 across the cutting assembly 200, the moving frame 310 continues to move along the first direction, conveying the stone slab 11 to the location of the conveying device. The fixing member 320 descends from the second height to the first height along a third direction. Since the first height is lower than the height of the cutting assembly 200, the fixing member 320 can bring the stone slab 11 close to the placement plane of the conveying device after descending. When several stone slabs 11 are already stacked on the conveying device, the specific value of the first height can be adaptively adjusted upwards so that the fixing member 320 stops descending to an appropriate position above the current stacking height. After descending to the correct position, the pick-and-place unit 321 releases the stone slab 11, and the stone slab 11 is placed smoothly on the conveying device in a horizontal posture.

[0173] After the stone slab 11 is placed, the fixing member 320 can rise again to a second height along a third direction, and the moving frame 310 moves along a first direction towards the support platform 100, returning to the area above the support platform 100, ready to perform the next stone slab 11 retrieval operation. At the same time, the cutting assembly 200 can move along the first direction towards the support platform 100, returning to the cutting working position to cut the next stone slab 11. The cutting operation and the unloading operation are carried out alternately or in conjunction, forming a continuous processing cycle.

[0174] Through the above-described process, the intelligent automatic unloading device achieves automated continuous operation of the stone slab 11 from cutting to unloading and placement. The fixing member 320, by switching between a first height and a second height, approaches the stone slab 11 from above the cutting assembly 200 before picking it up, and then again from above the cutting assembly 200 away from the support platform 100 after picking it up, before descending to the first height to place the stone slab 11 onto the conveying device. The picking and placing unit 321 completes the posture transformation of the stone slab 11 from a vertical to a horizontal state by rotating between a first posture and a second posture. The cutting assembly 200 retracts along the first direction to create a picking space when the fixing member 320 picks up the stone slab 11, providing ample operating area for the fixing member 320. The entire process achieves spatial coordination and action cooperation between the cutting component 200 and the handling component 300 in both the vertical and horizontal directions, reducing the waiting time between processes, lowering the risk of collision between the stone slab 11 and the cutting component 200, and improving the work efficiency, operational safety and action continuity of the stone slab 11 unloading process.
