[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application. The term “and / or” used herein includes any and all combinations of one or more related listed items.

[0041] Reference Figure 1In an embodiment of the present application, an automatic conveying device for sheet stamping is disclosed, which is arranged on one side of a stamping machine bed to replace manual carrying of sheets and serves as a matched device of the stamping machine bed. The automatic conveying device comprises a raw material feeding platform 1, a positioning platform 2, a finished product unloading platform 3, and a second carrying device 4.

[0042] The raw material feeding platform 1 comprises a feeding device 11 for feeding sheet raw materials and a first carrying device 12 for carrying the sheet raw materials. After the sheet raw materials are fed by the feeding device 11, the first carrying device 12 carries the sheet raw materials to the positioning platform 2 for positioning.

[0043] The finished product unloading platform 3 comprises an unloading device 31 for conveying sheet finished products and a carrier 32 for carrying the sheet finished products.

[0044] Further, the second carrying device 4 is provided with a first grabbing mechanism 41 for grabbing the sheet. The second carrying device 4 sequentially passes through the positioning platform 2, the stamping device, and the finished product unloading platform 3, corresponding to the material taking step, the stamping step, and the unloading step, respectively.

[0045] It should be noted that the material taking step at least comprises the following steps: the second carrying device 4 drives the first grabbing mechanism 41 to move to the positioning platform 2 to grab the sheet raw materials positioned by the positioning platform 2.

[0046] The stamping step at least comprises the following steps: the second carrying device 4 drives the first grabbing mechanism 41 to move to the stamping device to stamp the sheet raw materials to form sheet finished products.

[0047] The unloading step at least comprises the following steps: the second carrying device 4 drives the first grabbing mechanism 41 to move to the finished product unloading platform 3 to place the sheet finished products into the carrier 32, and the unloading device 31 conveys the sheet finished products.

[0048] Further, the raw material feeding platform 1, the positioning platform 2, and the finished product unloading platform 3 all adopt a modular structure (for example, as shown in Figure 1 ), each of which can be separated and adjusted independently. The second carrying device 4 conveys the sheets between the modules.

[0049] It should be noted that, since the device in the present application is adjusted by modularization, the position of the stamping machine bed is not shown in the drawings. For ease of understanding, the stamping machine bed can be arranged on the left side or the lower side of the position of the second carrying device 4 in the drawings. Figure 1

[0050] Reference is made to Figures 2 to 5 ​In an embodiment of the present application, in order to improve the feeding efficiency of the sheet material, a plurality of feeding devices 11 can be arranged on the raw material feeding platform 1. For example Figure 2 As shown in the figure, the number of feeding devices 11 is two, and they are arranged side by side on one side of the first conveying device 12.

[0051] Further, in order to transport the sheet material, the feeding device 11 includes a roller conveyor 111 and a lifting mechanism 114. The roller conveyor 111 is used to transport the sheet material to the designated position, and the lifting mechanism 114 is used to replenish the sheet material after the first conveying device 12 transports the sheet material to the positioning platform 2.

[0052] It should be noted that the first conveying device 12 has a corresponding conveying starting point and a conveying ending point. The sheet material is transported to the conveying starting point by the roller conveyor 111, and the lifting mechanism 114 is arranged at the conveying starting point. By lifting, the sheet material is lifted to a position where the first conveying device 12 can grasp.

[0053] The positioning platform 2 is arranged at the conveying ending point.

[0054] In an embodiment, the roller conveyor 111 as a whole follows the lifting mechanism 114 to lift.

[0055] In another embodiment, the roller conveyor 111 is sequentially divided into adjacent first and second conveying sections 112 and 113 along the conveying direction for conveying the sheet material. And the second conveying section 113 is arranged corresponding to the lifting mechanism 114, which can be lifted synchronously with the lifting mechanism 114, thereby reducing the load of the lifting mechanism 114 when lifting.

[0056] Further, the first conveying section 112 on the roller conveyor 111 adopts a passive roller group driven by external force, i.e. the first conveying section 112 is a non-powered roller group; the second conveying section 113 adopts a self-rotating active roller group, which is driven to operate by a motor.

[0057] Further, in order to make the sheet material on the second conveying section 113 have a relatively uniform position when transported to the positioning platform 2, a pushing mechanism 115 for preliminary arrangement and positioning of the sheet material is arranged on the feeding device 11. The pushing mechanism 115 includes a first pushing part 116 and a second pushing part 117 which can move towards each other. The first pushing part 116 and the second pushing part 117 are respectively located at the opposite sides of the second conveying section 113, and can move close to each other when a single sheet material or a stack of sheet materials runs to the second conveying section 113, thereby arranging the sheet material from both sides of the conveying direction.

[0058] In some embodiments, the first conveying device 12 comprises a linear motion module 121 and an extension arm 122 movably arranged on the linear motion module 121, wherein one end of the extension arm 122 is connected to the linear motion module 121, and the other end is provided with a second grabbing mechanism 123 capable of lifting, and the second grabbing mechanism 123 is used to grab the sheet material.

[0059] Further, the first conveying device 12 needs to transport the sheet material from the material supply platform 1 to the positioning platform 2 to complete the cross-module transportation.

[0060] Therefore, in some embodiments, the linear motion module 121 is close to one end of the positioning platform 2, and needs to extend out of the material supply platform 1 to extend towards the positioning platform 2, so that the extension arm 122 can move above the positioning platform 2, and the second grabbing mechanism 123 is lifted to place the sheet material on the positioning platform 2.

[0061] In another embodiment, referring to Figure 2 Or Figure 4 , the extension arm 122 can be provided in an L shape, one end of which is connected to the linear motion module 121, and the other end is bent and extends towards the setting direction of the positioning platform 2. Thus, the problem that the linear motion module 121 needs to extend out of the material supply platform 1 to extend towards the positioning platform 2 in the above-mentioned embodiment is solved. As compensation for the extension arm 122 at the conveying starting position, the end of the linear motion module 121 away from the positioning platform 2 needs to be extended, and the space below the linear motion module 121 can be used as a space for arranging electrical control equipment, improving the integrity of the material supply platform 1.

[0062] Referring to Figure 5 , in some embodiments of the present embodiment, the lifting mechanism 114 comprises a lifting seat 114a, a driving motor 114b, a gear 114c and a rack 114d. Wherein the driving motor 114b is connected to the lifting seat 114a, the gear 114c is connected to the motor shaft of the driving motor 114b and meshes with the rack 114d, and the rack 114d is independently connected to the material supply platform 1 with the lifting seat 114a. When the driving motor 114b drives the gear 114c to rotate, the lifting seat 114a moves along the setting direction of the rack 114d, thereby achieving lifting.

[0063] Further, the second conveying section 113 comprises a roller group 113a and a motor 113b for driving the roller group to rotate, and the roller group 113a and the motor 113b are both connected to the lifting seat 114a and synchronously lifted with the lifting seat 114a.

[0064] Referring to Figure 3In some embodiments, the positioning platform 2 is arranged on the base so as to have a certain height, which can be used to reduce the height that the second grabbing mechanism 123 needs to drop. In addition, the upper surface of the positioning platform 2 is provided with a first limiting block 21, a second limiting block 22, and a third pushing mechanism 23 and a fourth pushing mechanism 24, the first limiting block 21 and the second limiting block 22 correspond to two adjacent edges of the sheet material respectively; the third pushing mechanism 23 has a movement direction towards the first limiting block 21, and the fourth pushing mechanism 24 has a movement direction towards the second limiting block 22, which are used to push the sheet material to a specific position.

[0065] With reference to Figures 6 to 8 In some embodiments, the finished product unloading platform 3 has a table surface 33 matched with the second conveying device 4, which forms a height convenient for the unloading operation of the second conveying device 4, so that the carrier can catch the sheet material finished product on the first grabbing mechanism 41. The unloading device 31 is partially located on the table surface 33, which is used to transmit the carrier 32 and the sheet material finished product on the carrier.

[0066] Further, the unloading device 31 comprises a first conveying mechanism 311, a second conveying mechanism 312, and a third conveying mechanism 313 which are sequentially arranged. The second conveying device 4 is located on the table surface 32 of the second conveying mechanism 312, the transmission direction of the first conveying mechanism 311 is towards the second conveying device 4, and the transmission direction of the third conveying mechanism 313 is away from the second conveying device 4, which constitutes a U-shaped loop line, thereby saving space.

[0067] Further, with reference to Figure 7 The first conveying mechanism 311 is sequentially provided with adjacent first translation sections and first lifting sections, and the carrier 32 is transmitted from the first conveying mechanism 311 to the second conveying mechanism 312 through the first lifting sections of the first conveying mechanism 311; the second conveying mechanism 312 is sequentially provided with adjacent second lifting sections and second translation sections, and the carrier 32 is transmitted from the second conveying mechanism 312 to the third conveying mechanism 313 through the second lifting sections of the second conveying mechanism 312. The first lifting sections and the second lifting sections are respectively arranged on the first conveying mechanism 311 and the second conveying mechanism 312, which are used to lift the carrier 32 to the height of the table surface 32, and transport the sheet material finished product downward, thereby saving the manpower for conveying the sheet material finished product downward from the height of the table surface 32.

[0068] It should be noted that the first lifting sections and the second lifting sections have similar structures to the second conveying section 113 and the lifting mechanism 114, and can be synchronized with the transmission and lifting.

[0069] With reference to Figure 9 The second conveying device 4 adopts a mechanical arm structure.

[0070] Any technical features in the above-described embodiments can be combined in any manner, and for the sake of brevity, the foregoing descriptions of various embodiments do not describe all possible combinations. However, it should be understood that any combination of these technical features, unless specifically excluded, is within the scope of the present disclosure. Technical features in different embodiments can be implemented in the same figure while the figure is regarded as disclosing a combination of the embodiments involved.

[0071] The above-described embodiments are merely illustrative of several embodiments of the present application, and the descriptions are relatively specific and detailed, but should not be understood as limiting the scope of the patent application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application.
