[0073] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0074] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0075] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0076] like Figure 1 As shown, the embodiment of the present application provides a clamping device 32, which includes a frame 11, a first conveying assembly 12 and a second conveying assembly 13. The frame 11 forms the main body and installation base of the clamping device 32; the first conveying assembly 12 is fixedly or liftably arranged on the frame 11, and the material can move with the first conveying assembly 12; the second conveying assembly 13 is liftably arranged on the frame 11; the second conveying assembly 13 and the first conveying assembly 12 are arranged at intervals in the vertical direction, and a conveying space for conveying sheet materials is formed between the second conveying assembly 13 and the first conveying assembly 12. The sheet materials are clamped between the two conveying assemblies through the cooperation of the two conveying assemblies, and the sheet materials move with the conveying assemblies to prevent wear between the sheet materials and the clamping device; the first conveying assembly 12 or the second conveying assembly 13 is liftably arranged on the frame 11, so that the sheet materials can be clamped and released, and the sheet materials can be taken and placed.

[0077] In addition, since the sheet material moves with the conveying assembly, the sheet material can be picked up and placed without changing the position of the clamping device 32. This can not only improve the positioning accuracy between the clamping device 32 and the sheet material, but also reduce the jitter or shaking generated during the picking and placing of the sheet material, thereby improving the stability of the picking and placing of the sheet material.

[0078] Furthermore, the clamping device 32 includes at least two first conveying components 12, and each first conveying component 12 is spaced apart along the length direction of the frame 11. Similarly, the clamping device 32 includes at least two second conveying components 13, and each second conveying component 13 is spaced apart along the length direction of the frame 11. The second conveying components 13 are arranged one-to-one with the first conveying components 12, so as to form multiple clamping points for the material, thereby improving the stability of material clamping and conveying. Further, the clamping device 32 includes an elastic component, which can be a spring, a reed or rubber, etc. When the sheet material enters the conveying space, the elastic component is used to elastically press the sheet material to avoid damage such as scratches caused by excessive force on the surface of the sheet material.

[0079] In one embodiment, the elastic component can be connected to the first conveying component 12 and the second conveying component 13. That is, the first conveying component 12 and the second conveying component 13 are respectively provided with elastic components, so that the upper and lower surfaces of the sheet material are elastically pressed to prevent the surface of the sheet material from being damaged such as scratches due to excessive force.

[0080] In another embodiment, the elastic component is connected to the second conveying component 13, that is, the first conveying component 12 is not provided with an elastic component, and only the second conveying component 13 is provided with an elastic component. The clamping force between the second conveying component 13 and the first conveying component 12 is adjusted by the elastic component to avoid damage such as scratches caused by excessive force on the surface of the sheet.

[0081] Furthermore, the clamping device 32 also includes a clamping drive member 14, which is fixedly connected to the frame 11 and is used to drive the first conveying assembly 12 and the second conveying assembly to clamp or release the material plate. In other words, the clamping drive member 14 drives the first conveying assembly 12 or the second conveying assembly 13 to move up and down, so that the first conveying assembly 12 and the second conveying assembly are close to or away from each other, thereby actively clamping and releasing the material.

[0082] The clamping drive 14 can be any mechanism capable of outputting linear motion, such as a screw nut mechanism, a gear rack mechanism or a cylinder. When the clamping drive 14 drives the first conveying assembly 12 and the second conveying assembly 13 to approach each other, the second conveying assembly 13 and the first conveying assembly 12 clamp the material, so that the material can be picked up and conveyed to a predetermined position; when the clamping drive 14 drives the first conveying assembly 12 and the second conveying assembly 13 to move away from each other, the second conveying assembly 13 and the first conveying assembly 12 release the material and place the material at a predetermined position.

[0083] Furthermore, the first conveying assembly 12 includes a first pulley 121, and the second conveying assembly 13 includes a second pulley 131; the first pulley 121 and the second pulley 131 rotate synchronously, so that a conveying space for conveying the sheet material is formed between the first pulley 121 and the second pulley 131. When the sheet material is clamped in the conveying space, the first pulley 121 and the second pulley 131 are respectively pressed against the upper and lower surfaces of the sheet material, thereby pushing the sheet material to move along the conveying direction, thereby realizing the conveying of the sheet material.

[0084] Furthermore, the first conveying assembly 12 includes at least two first pulleys 121, each of which is arranged in sequence along the conveying direction of the first conveying assembly 12, so that multiple contact points can be formed along the surface of the sheet material, thereby improving the stability of the sheet material clamping and conveying, and preventing the sheet material from shifting or shaking. Similarly, the second conveying assembly 13 includes at least two second pulleys 131, each of which is arranged in sequence along the conveying direction of the second conveying assembly 13.

[0085] Furthermore, the first conveying assembly 12 is a belt conveying assembly, and the first pulley 121 is a driving wheel or a driven wheel of the belt conveying assembly, so that a continuous flexible support surface is formed above the first pulley 121, which can increase the support area of ​​the sheet material, increase the stability of sheet material transportation, and reduce the bumps or wear generated during sheet material transportation. Similarly, the second conveying assembly 13 can also be a belt conveying assembly, and the second pulley 131 is a driving wheel or a driven wheel of the belt conveying assembly.

[0086] Specifically, taking the first conveying assembly 12 as an example, the specific structure of the belt conveying assembly is described in detail. The belt conveying assembly includes a mounting frame 122, two first pulleys 121 (respectively a driving wheel and a driven wheel) and a belt 123. The mounting frame 122 is connected to the frame 11 to achieve the overall installation and fixation of the belt 123 conveying assembly; the driving wheel and the driven wheel are arranged at intervals along the length direction of the mounting frame 122, and the belt 123 is coated on the outer surface of the driving wheel and the driven wheel. The driving wheel can be directly or indirectly connected to the motor, and the motor drives the driving wheel to rotate, and the belt 123 and the driven wheel rotate together with the driving wheel.

[0087] Furthermore, the clamping device also includes a gear drive assembly 15, which is simultaneously connected to the first conveying assembly 12 and the second conveying assembly 13, thereby ensuring that the first conveying assembly 12 and the second conveying assembly 13 can rotate synchronously, preventing the first conveying assembly 12 and the second conveying assembly 13 from slipping and affecting the normal clamping and conveying of the sheet material.

[0088] Further, the gear drive assembly 15 includes a driving member 151 (for example, a motor, etc.), a first gear drive shaft 152 meshing with the driving member 151, a second gear drive shaft 153 meshing with the first gear drive shaft 152, one end of the first gear drive shaft 152 is transmission-connected to the first conveying assembly 12, and one end of the second gear drive shaft 153 is transmission-connected to the second conveying assembly 13. It can adapt to the installation space of the frame 11 and change the rotation speed as needed, thereby ensuring the smooth conveying of the sheet material.

[0089] Further, the first gear drive shaft 152 includes a first drive gear 1521, a first transmission shaft 1522, and a first transmission gear 1523 connected in sequence. The second gear drive shaft 153 includes a second drive gear 1531, a second transmission shaft 1532, and a second transmission gear 1533 connected in sequence. The first drive gear 1521 is meshed with the second drive gear 1531, so that the first gear drive shaft 152 and the second gear drive shaft 153 rotate synchronously; the first transmission gear 1523 is transmission-connected to the first conveying assembly 12, and the second transmission gear 1533 is transmission-connected to the second conveying assembly 13.

[0090] like Figure 2 As shown, the embodiment of the present application also provides a sheet material conveying assembly, which includes a track portion 2, a conveying portion 3 and a whole plate portion 4. The conveying portion 3 and the whole plate portion 4 can be movably mounted on the track portion 2, and the conveying portion 3 includes any one of the clamping devices 32 provided in the embodiment of the present application. The track portion 2 guides the conveying portion 3 and the whole plate portion 4; the conveying portion 3 is used to clamp and convey the sheet material, and the whole plate portion 4 is used to arrange the sheet material conveyed by the conveying portion 3 so that the multi-layer sheet materials can be aligned with each other, and cooperate with the conveying portion 3 to clamp and convey the sheet material to prevent the sheet material from escaping from the effective clamping range of the conveying portion 3.

[0091] Furthermore, the conveying part 3 includes a first movable part 31 and a clamping device 32 slidably connected to the track part 2. The first movable part 31 is used to drive the clamping device 32 to move in a horizontal direction, so that the clamping device 32 approaches or moves away from the target position to achieve clamping and conveying of the sheet material.

[0092] Furthermore, the whole plate part 4 includes a second movable part 41 slidably connected to the track part and a clapping mechanism 42 installed on the second movable part 41. The second movable part 41 is used to drive the clapping mechanism 42 to move in the horizontal direction, so that the clapping mechanism 42 is close to or away from the target position to achieve the sorting of the sheet material.

[0093] Specifically, the clapping mechanism 42 is in the shape of a plate, and the clapping mechanism 42 can be pressed against the end of the sheet material, so that the sheet material is aligned up and down; the clapping mechanism 42 can move in the vertical direction, so that the clapping mechanism 42 can arrange each layer of the sheet material in sequence; the clapping mechanism 42 can approach the sheet material and move away from the sheet material in the horizontal direction, so as to ensure that the clapping mechanism 42 is adapted to the length of the sheet material.

[0094] like Figure 3 As shown, the embodiment of the present application also provides a feeding device, which includes a mobile frame 5, a material box 6 and any one of the above-mentioned sheet material conveying components. The mobile frame 2 can be a logistics vehicle such as an AGV; the material box 6 is connected to the mobile frame 2 and is used to hold the sheet material; the track part 2 can be raised and lowered on the mobile frame 2, so that the clamping device 32 and the sheet material are at the same height position, ensuring smooth clamping and smooth conveying of the sheet material.

[0095] Furthermore, the first movable part 31 drives the clamping device 32 to approach the material box 6 and move away from the material box 6 in the horizontal direction, thereby ensuring that the clamping device 32 can clamp the sheet material and preventing the clamping device 32 from idling. The clamping device 32 puts the sheet material into the material box 6 or takes the sheet material out of the material box 6, thereby realizing the automatic loading and unloading of the sheet material.

[0096] Specifically, the material box 6 can be set as a single-layer box structure or a multi-layer box structure. A horizontally extending storage space can be set in the material box 6, and a take-in and put-out port 61 connected to the storage space can be set on one side of the material box 6, and the sheet material is inserted into the material box 6 or taken out from the material box 6 through the take-in and put-out port 61. The clamping device 62 is accurately aligned with the take-in and put-out port 61 by lifting and positioning, so that the clamping space of the clamping device 62 is directly at the height position where the sheet material is located, so that the sheet material is smoothly transported between the clamping device 62 and the material box 6. The clamping device 62 can be provided with an edge-finding sensor to ensure that the clamping device can accurately clamp the sheet material.

[0097] Furthermore, a tail opening 62 may be provided on one side of the material box 6, and the tail opening 62 is arranged opposite to the loading and unloading opening 61. A portion of the sheet material can pass through the tail opening 62 and extend out of the material box 6, so as to reduce the restriction of the size of the material box 6 on the size specifications of the sheet material and improve the adaptability of the material box 6 to the sheet material.
