Description

Technical Field

[0001] This invention relates to the field of automation control, and more specifically, to a sheet feeding device. Background Technology

[0002] When aluminum sheets are stacked together, they often stick together due to factors such as grease, water vapor, and static electricity, making them difficult to separate. This adhesion poses a significant challenge to automated production processes. Current technologies often rely on manual operation to separate stacked aluminum sheets one by one; however, this method has obvious efficiency bottlenecks, severely limiting the overall efficiency of the production line. Summary of the Invention

[0003] The purpose of this invention is to provide a sheet feeding device that automates the production process and improves the overall efficiency and operational efficiency of the production line.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sheet feeding device, comprising:

[0005] A placement platform is provided, which forms a placement space for placing stacks of aluminum plates. A lifting window is provided on the placement platform, and the lifting window is located below the placement space.

[0006] A lifting mechanism is provided below the placement platform, and the lifting mechanism extends into the placement space through the lifting window;

[0007] A sheet-separating mechanism is disposed on one side of the placement space to separate aluminum plates on the placement table; a positioning mechanism is disposed on one side of the placement table, the positioning mechanism including a positioning platform; and

[0008] A transport mechanism is disposed above the placement platform. The transport mechanism is used to transport the aluminum plate on the placement platform to the positioning platform. The transport mechanism includes a plate assembly, a plurality of first suction members and at least two fixing cylinders mounted on the plate assembly, and a second suction member disposed on the fixing cylinders. The second suction member includes a rod and a suction cup mounted on the rod, and the rod extends at least partially into the suction cup.

[0009] Furthermore, the sheet-splitting mechanism includes a mounting column fixed on the placement platform, a sheet-splitting module disposed on one side of the mounting column, and a pressing module disposed on the other side of the mounting column. The pressing module includes a pressing cylinder and a pressing block disposed on the pressing cylinder.

[0010] Furthermore, the number of the sheet-splitting mechanisms is at least two, and each pair of sheet-splitting mechanisms is arranged opposite each other on both sides of the placement space to form a group.

[0011] Furthermore, the second adsorption member also includes an elastic member sleeved on the rod body, a locking part is formed at the bottom of the rod body, the suction cup can slide relative to the rod body and is restricted from sliding out by the locking part, and the lower end of the elastic member abuts against the suction cup.

[0012] Furthermore, the number of placement platforms is at least two, and the sheet feeding device also includes a slide rail assembly disposed below the placement platform and a drive component for driving the placement platform to move on the slide rail assembly.

[0013] Furthermore, a number of limiting posts are vertically formed on the placement platform, and the limiting posts surround a placement space for accommodating the aluminum plate.

[0014] Furthermore, a fixing plate is provided at the bottom of the limiting post, and a sliding structure is formed between the fixing plate and the placement platform.

[0015] Furthermore, the positioning mechanism also includes a plurality of positioning blocks disposed on the positioning platform and a positioning cylinder for driving the relative movement of the positioning blocks, wherein the plurality of positioning blocks surround and form a positioning space for the aluminum plate.

[0016] Furthermore, a detection element is provided on one side of the positioning block to detect the height position of the aluminum plate placed on the positioning platform.

[0017] Furthermore, the lifting mechanism includes a lifting cylinder and a lifting plate disposed on the lifting cylinder.

[0018] The beneficial effects of this invention are as follows: The sheet-separating and feeding equipment of this application achieves the separation of aluminum plates through a sheet-separating mechanism. Furthermore, since the second adsorption element is mounted on a fixed cylinder, and the rod portion of the second adsorption element extends into the suction cup, after the conveying mechanism adsorbs the aluminum plate located above through the first and second adsorption elements, the rod can be driven by the fixed cylinder to impact the adsorbed aluminum plate. If there is another aluminum plate adhering below this plate, the two aluminum plates will separate due to the impact, thus further ensuring that only one aluminum plate is conveyed. In summary, the combined action of the sheet-separating mechanism and the second adsorption element not only ensures the smooth separation of the aluminum plates but also automates the entire production process, significantly improving the overall efficiency and operational efficiency of the production line.

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see Figures 1 to 4 The sheet-feeding device 100 shown in a preferred embodiment of the present invention is used to separate stacked aluminum plates 200 and transport them individually to facilitate subsequent work and improve automation. The aluminum plates 200 can be unfilmed products, partially filmed products, or products with full film.

[0030] The sheet-feeding equipment 100 includes a frame 10, a placement platform 20 on the frame 10 for placing stacked aluminum sheets 200, a lifting mechanism 30 below the placement platform 20, a sheet-separating mechanism 40 on the placement platform 20, a positioning mechanism 50 on one side of the placement platform 20, and a conveying mechanism 60 for separating and sequentially transporting each aluminum sheet 200 on the placement platform 20 to the positioning mechanism 50. The placement platform 20 forms a placement space 21 for placing stacked aluminum sheets 200, and a lifting window 22 is provided on the placement platform 20. The lifting window 22 is located below the placement space 21, and the lifting mechanism 30 extends into the placement space 21 through the lifting window 22. The sheet-separating mechanism 40 is specifically located on one side of the placement space 21 and is used to separate the aluminum sheets 200 on the placement platform 20. Specifically, the sheet-separating mechanism 40 is used to separate the topmost aluminum sheet 200 from the stacked aluminum sheets 200. The positioning mechanism 50 includes a positioning stage 51 for placing the separated aluminum plate 200. A conveying mechanism 60 is disposed above the placement stage 20 and is movable between the placement stage 20 and the positioning stage 51. The conveying mechanism 60 includes a plate assembly 61, a plurality of first suction members 62 mounted on the plate assembly 61, at least two fixing cylinders 63, and second suction members 64 disposed on the fixing cylinders 63. The second suction member 64 includes a rod 641 and a suction cup 642 mounted on the rod 641, with the rod 641 at least partially extending into the suction cup 642.

[0031] The sheet-separating and feeding equipment 100 separates the aluminum plates 200 through the sheet-separating mechanism 40. Since the second adsorption member 64 is mounted on the fixed cylinder 63, and the rod 641 of the second adsorption member 64 extends into the suction cup 642, after the conveying mechanism 60 adsorbs the aluminum plate 200 above it using the first adsorption member 62 and the second adsorption member 64, the fixed cylinder 63 can drive the rod 641 to impact the adsorbed aluminum plate 200. If there are other aluminum plates 200 adhering below this plate, they will separate due to the impact, thus further ensuring that only one aluminum plate 200 is conveyed. In summary, the combined action of the sheet-separating mechanism 40 and the second adsorption member 64 not only ensures the smooth separation of the aluminum plates 200 but also automates the entire production process, significantly improving the overall efficiency and operational efficiency of the production line.

[0032] It should be noted that in this embodiment, when the rod 641 strikes the adsorbed aluminum plate 200, the uppermost aluminum plate 200 may undergo slight deformation. However, this deformation will not affect subsequent operations.

[0033] In this embodiment, there is one lifting mechanism 30, one positioning mechanism 50, and one conveying mechanism 60, all positioned at designated locations. There are two placement platforms 20, which are referred to as the first placement platform and the second placement platform for ease of description, and are arranged side-by-side. In other embodiments, the number of placement platforms 20 may be greater than two, depending on actual needs. By setting two or more placement platforms 20, work efficiency can be improved; that is, when one placement platform 20 is located below the conveying mechanism 60, material can be loaded onto the other placement platform 20 during sheet-separation and conveying operations. To facilitate the movement of the two placement platforms 20, in one embodiment, the sheet-separation and loading device 100 further includes a slide rail assembly 71 disposed below the placement platform 20 and a drive component 72 for driving the placement platform 20 to move on the slide rail assembly 71. The slide rail assembly 71 is arranged between the frame 10 and the placement platform 20. The slide rail assembly 71 can adopt an existing structure, such as a slide rod 711 fixed on the frame 10 and a slide sleeve 712 sleeved on the slide rod 711 and fixed below the placement platform 20.

[0034] Please combine Figure 1 and Figure 2To prevent the stacked aluminum plates 200 from collapsing when placed on the placement platform 20, and to facilitate the subsequent sheeting by the sheeting mechanism 40, in this embodiment, several limiting posts 23 are vertically formed on the placement platform 20, forming a placement space 21 for accommodating the stacked aluminum plates 200. A fixing plate 24 is provided at the bottom of each limiting post 23, and the limiting posts 23 are locked to the placement platform 20 by the fixing plate 24 and fasteners (not shown). A sliding structure is also formed between the fixing plate 24 and the placement platform 20. Specifically, the sliding structure includes several sliding grooves 211, with each fixing plate 24 embedded in a corresponding sliding groove 211. When the position of the fixing plate 24 needs to be adjusted, the fasteners on the fixing plate 24 are loosened, allowing the fixing plate 24 to move within the sliding groove 211 until it reaches the desired position. Then, the fasteners are tightened to lock the fixing plate 24 onto the placement platform 20. The sliding structure allows the position of the limiting post 23 on the placement platform 20 to be adjusted, thereby adjusting the size of the placement space 21. This accommodates different aluminum plate 200 sizes and improves the applicability of the sheet feeding device 100. Furthermore, in this embodiment, by embedding the fixing plate 24 into the sliding groove 211, the upper surface of the fixing plate 24 is made parallel to the placement plane of the placement platform 20. This prevents the fixing plate 24 from protruding from the placement platform 20, resulting in a more compact overall structure and more stable placement of the aluminum plate 200.

[0035] The sheet-splitting mechanism 40 includes a mounting column 41 fixed on the placement platform 20, a sheet-splitting module 42 disposed on one side of the mounting column 41, and a pressing module 43 disposed on the other side of the mounting column 41. The pressing module 43 includes a pressing cylinder 431 and a pressing block 432 disposed on the pressing cylinder 431. In this embodiment, at least two sheet-splitting mechanisms 40 are provided on each placement platform 20. Each pair of sheet-splitting mechanisms 40 is disposed opposite to both sides of the placement space 21 to form a group. In this embodiment, a group of sheet-splitting mechanisms 40 on each placement platform 20 is arranged on the long side of the aluminum plate 200. When the sheet-splitting module 42 is working, the pressing module 43 first presses against one side of the stacked aluminum plates 200, so that the side edges of the stacked aluminum plates 200 are flush, thereby avoiding sheet-splitting errors due to uneven side edges, that is, simultaneously separating two or more sheets from the stacked aluminum plates 200. In one embodiment, the pressing block 432 is a plastic block. The force applied by the pressing module 43 to the aluminum plate 200, based on previous tests, is sufficient to push the sides of the stacked aluminum plates 200 to be flush, and also prevents the separating module 42 from failing to separate the aluminum plates 200. In other words, the force applied by the pressing module 43 to the aluminum plate 200 is greater than the horizontal friction force of the aluminum plate 200, but less than the separating force applied by the separating module 42. The separating module 42 uses existing technology and will not be described in detail here. It generally includes a separating plate and a driving member. The separating plate has an inclined surface with teeth formed on it. When the inclined surface abuts against the stacked aluminum plates 200, the teeth will abut against the topmost aluminum plate 200. Then, the driving member 72 drives the teeth to move upwards, pushing the abutted aluminum plate 200 slightly upwards, reducing the tightness between them.

[0036] Please combine Figure 1 and Figure 3 The lifting mechanism 30 includes a lifting cylinder 31 fixed to the frame 10 and a lifting plate 32 disposed on the lifting cylinder 31. In this embodiment, since the height positions of the sheet-splitting module 42 and the pressing module 43 do not change, the lifting mechanism 30 is activated after each sheet of aluminum plate 200 is split. The lifting plate 32 lifts the stack of aluminum plates 200 upwards until the height of the uppermost aluminum plate 200 moves to the height position corresponding to that of the sheet-splitting mechanism 40. Then, the pressing module 43 and the sheet-splitting module 42 perform their respective tasks. In this embodiment, the implementation of the lifting plate 32 ensures that the stack of aluminum plates 200 moves smoothly upwards.

[0037] Please combine Figure 1 and Figure 4The conveying mechanism 60 also includes a linear module 66 fixed to the frame 10 by a conveying arm 65 and a lifting cylinder 67 disposed on the linear module 66. The plate assembly 61 is disposed on the lifting cylinder 67. In this embodiment, the first suction member 62 and the second suction member 64 have the same structure. Taking the second suction member 64 as an example, the second suction member 64 also includes an elastic member 643 sleeved on the rod 641. A locking part (not shown) is formed at the bottom of the rod 641. The suction cup 642 can slide relative to the rod 641 and is restricted from sliding out by the locking part. The lower end of the elastic member 643 abuts against the suction cup 642. The first adsorption element 62 and the second adsorption element 64 move horizontally. Specifically, the first adsorption element 62 and the second adsorption element 64 are fixed to the plate assembly 61 and the fixing cylinder 63 respectively by the assembly plate 68. The assembly plate 68 has a long sliding groove (unnumbered). The top of the rod 641 of the first adsorption element 62 and the second adsorption element 64 is inserted into the long sliding groove, and the top of the rod 641 is also provided with a locking bolt (unnumbered). The locking bolt locks the rod 641 onto the assembly plate 68. The position of the first adsorption element 62 and the second adsorption element 64 can be adjusted by the cooperation of the locking bolt, the long sliding groove and the rod 641 to meet the handling requirements of aluminum plates 200 of different sizes.

[0038] In this embodiment, there are four first adsorption elements 62 and two second adsorption elements 64. When adsorbing the aluminum plate 200, the two second adsorption elements 64 are located approximately inside the middle of the short side of the aluminum plate 200.

[0039] Please combine Figure 1 and Figure 5 The positioning mechanism 50 also includes a support frame 52 for fixing the positioning platform 51 to the frame 10, a plurality of positioning blocks 53 disposed on the positioning platform 51, and a positioning cylinder 54 for driving some of the positioning blocks 53 to move relative to each other. The positioning cylinder 54 is fixed on the positioning platform 51, and some of the positioning blocks 53 are mounted on the plunger of the positioning cylinder 54. The plurality of positioning blocks 53 surround and form a positioning space for the aluminum plate 200. The positioning space can be adjusted by the positioning blocks 53 and the positioning cylinder 54 to adapt to the placement requirements of aluminum plates 200 of different sizes, thereby improving the usability of the positioning mechanism 50. A detection element 55 is provided on one side of the positioning block 53 to detect the height position of the aluminum plate 200 placed on the positioning table 51. The height position of the aluminum plate 200 placed on the positioning table 51 is obtained by the detection element 55. Then, the control system compares whether the obtained height position is within the preset height position threshold. If it is, it can be determined that the aluminum plate 200 moved on the positioning table 51 is one piece. If it exceeds the threshold, it can be determined that the number of aluminum plates 200 moved to the positioning table 51 is more than one piece. In this way, it can further ensure whether the number of moved aluminum plates 200 is correct and ensure the stability of subsequent processes.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
