[0029] Optionally, the clamping range of the first gripper 20 and the second gripper 30 is set to correspond to the dimensions of the first material and the second material. Specifically, the length, width, and height of the first material and the second material are 1.1m × 1m × 1.1m, and the dimensional compatibility range is ±20mm. Correspondingly, the length, width, and height of the first gripper 20 and the second gripper 30 are 1975mm × 680mm × 1488mm, and the clamping range of the first gripper 20 and the second gripper 30 in the third direction Y is 680mm ± 200mm.

[0030] The destacking mechanism 100 of this utility model is applied to a logistics line before the barcode scanning upon entry into the warehouse.

After the first material below is automatically put into the warehouse, the second material will be put into the warehouse. The destacking mechanism 100 of this utility model adopts fully automatic unloading, reduces the cross-operation of forklifts and manual labor, reduces safety risks, and improves the efficiency of material entry into the warehouse, reducing the traditional manual unloading time of 45 minutes / vehicle to 15 minutes / vehicle.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, the first drive assembly 40 includes a first drive member 41, a first nut 45, a second nut, a first lead screw 42, and a second lead screw 43. The first lead screw 42 and the second lead screw 43 are connected and coaxially arranged. The first drive member 41 is used to drive the first lead screw 42 and the second lead screw 43 to rotate. The first lead screw 42 is rotatably connected to the first nut 45, and the first nut 45 is fixedly connected to the first gripper 20. The second lead screw 43 is rotatably connected to the second nut, and the second nut is fixedly connected to the second gripper 30. The rotation direction of the thread of the first lead screw 42 is opposite to the rotation direction of the thread of the second lead screw 43.

[0032] Optionally, the first driving component 41 can be driven by a motor, hydraulically, or pneumatically, without limitation.

Optionally, the first driving component 41 is disposed on one side of the support frame 10 in the second direction X.

[0033] Optionally, the first lead screw 42 and the second lead screw 43 can be an integral structure. The materials of the first lead screw 42 and the second lead screw 43 can be high-carbon chromium bearing steel (such as GCr15), alloy tool steel (such as 9Mn2V), etc., without limitation. The materials of the first nut 45 and the second nut can be copper alloy (such as ZQSn6-6-3), high-strength plastic (such as POM), or the same as the materials of the first lead screw 42 and the second lead screw 43, without limitation.

[0035] By setting the lead screw and nut to form a helical pair through threaded engagement, when the first driving member 41 drives the lead screw to rotate, the nut moves linearly along the axial direction, realizing the conversion of motion mode. The opposite threads of the first lead screw 42 and the second lead screw 43 enable the first gripper 20 and the second gripper 30 to move towards or relative to each other, thereby facilitating the gripping and placement of the second material.

[0036] Please refer to Figure 3 In one embodiment, the first drive assembly 40 further includes a connecting rod 44, which is coaxially arranged with the first lead screw 42 and the second lead screw 43.

[0038] Optionally, the connecting rod 44 is fixed to the lead screw via a detachable structure (such as a flange coupling, expansion sleeve, or threaded connection) to facilitate the installation and maintenance of the first drive assembly 40. If it is necessary to adjust the load capacity of the first drive assembly 40 (such as handling larger cargo), it can be done by replacing the lead screw with one of different diameters or pitches and rematching the length of the connecting rod 44, without redesigning the entire drive assembly.

[0039] The connecting rod 44 rigidly connects the first lead screw 42 and the second lead screw 43, so that the two rotate synchronously, thereby distributing the driving force to the two lead screws, which can significantly improve the load-bearing capacity of the system, especially suitable for heavy-duty destacking scenarios (such as grabbing large goods and multi-layer stacks).

The slider and the slide rail form a rigid connection to withstand the reaction force (such as the weight of the goods and inertial force) during destacking, reducing the deformation of the destacking mechanism 100.

[0045] Please refer to Figure 1 In one embodiment, the first gripper 20 includes a connected side frame 21 and a support portion 22.

The connecting portion 25 is provided to enhance the connection strength between the first gripper 20 and the support frame 10.

[0050] The side frame 21 is provided so that the second material with a certain height can be accommodated between the first gripper 20 and the support frame 10. The support part 22 is provided to form a limiting effect with the support frame 10 in the first direction Z, so as to prevent the second material from separating from the first gripper 20 and the second gripper 30, and to ensure the safety of the destacking mechanism 100.

[0059] The clamping plate 24 is provided to increase the contact area between the destacking mechanism 100 and the second material, so as to prevent the first material from detaching from the destacking mechanism 100 through the gap of the side frame 21 and enhance the safety of the destacking mechanism 100.

[0060] Please refer to Figure 1 In one embodiment, the destacking mechanism 100 further includes a first detection element 61, which is disposed on the first gripper 20 and is used to detect the gripping state between the first gripper 20 and the second material.

[0063] Optionally, the first detection element 61 may also be disposed on the side of the second gripper 30 facing away from the first gripper 20.

[0064] Optionally, the first detection element 61 can be a pressure sensor, a proximity switch (which detects whether the material is in place by emitting an electromagnetic field or infrared light), a photoelectric sensor (which detects the presence of the material or its positional shift), a torque sensor (which detects the driving torque of the gripper), etc., without limitation.

[0065] The first detection component is set to detect the clamping state between the first gripper 20 and the second material, that is, to detect whether the first gripper 20 is clamped in place with the second material, so as to prevent the second material from disengaging from the first gripper 20 and the second gripper 30 during the clamping process, thereby improving the safety of the destacking mechanism 100.

[0068] Optionally, the second detection element 62 may be disposed on the side of the support frame 10 facing the support surface in the first direction Z, and the second detection element 62 may be disposed between the first gripper 20 and the second gripper 30.

[0069] Because there are multiple types of materials entering the warehouse, a second detection element 62 is set up to automatically identify single / layer materials. When the single layer material is lower than the preset value, the destacking mechanism 100 does not destacking. When the material is higher than the preset value, the first gripper 20 and the second gripper 30 of the destacking mechanism 100 automatically destacking, which helps to improve work efficiency and avoids damage to single layer materials by forcibly destacking.

The third detection component 63 can be a pressure sensor (directly detects the pressure on the surface of the stack), a displacement sensor (detects the deformation of the surface of the stack), a proximity switch (detects the presence or positional deviation of the stack), a vision sensor (intelligently detects the pressure and abnormality of the stack), a torque sensor (detects abnormality of the driving torque of the gripper), etc., without limitation.

[0072] Optionally, the destacking mechanism 100 also includes an alarm element. If the third detection element 63 detects that the stack is under pressure, the alarm element issues a warning signal and stops the operation of the destacking mechanism 100.

[0073] The third detection component 63 is set to detect the downward pressure distance of the support component, the first gripper 20 and the second gripper 30 when they move in the first direction Z, so as to avoid the destacking mechanism 100 pressing down too much, causing damage to the stack or the destacking mechanism 100, and improving the service life of the destacking mechanism 100.

[0074] In one embodiment, the destacking mechanism 100 further includes a second drive assembly connected to the support frame 10, which is used to drive the support frame 10 to move in the first direction Z.

The second drive assembly is connected and fixed to the connecting plate 70. The connection method between the second drive assembly and the connecting plate 70 can be welding, bonding, screwing, snap-fitting, etc., without limitation.

[0077] The second drive component is set up to enable the first gripper 20 and the second gripper 30 to move up and down in the first direction Z, so that the first material can be transported smoothly after the second material is clamped, and the destacking mechanism 100 can place the second material for transport again after the first material is transported.

[0078] This utility model provides a material transportation system, including a transportation mechanism and a destacking mechanism 100 as described in any of the aforementioned embodiments. The transportation mechanism is used to transport stacks, and the destacking mechanism 100 is disposed above the transportation mechanism.

[0079] Optionally, the transportation mechanism can be forklifts, conveyor belts, etc., without restriction.

[0080] After the first and second materials stacked together are transported from the transport mechanism to the destacking mechanism 100, the first gripper 20 and the second gripper 30 grip the second material on top, and the transport mechanism continues to transport the first material below. After the first material is automatically stored, the destacking mechanism 100 places the gripped second material on the transport mechanism for storage. The destacking mechanism 100 performs a reciprocating gripping and lifting motion, and the transport mechanism performs the transport work, realizing fully automatic unloading, reducing the cross-operation of machinery and manual labor, reducing safety risks, and improving the storage efficiency of materials.
