Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a sheet material positioning device. Background Art

[0002] A sheet material protective film, also known as a sheet material, is mostly used to stick it on the outer shell of an electronic product after the processing of the electronic product, for example: sticking it on a computer screen, the outer side of a computer plastic shell, etc. Thus, it can avoid the electronic product from being scratched or dusty during subsequent transportation, achieving the corresponding protection purpose. The sheet material will be cut to size according to the specific product, and a large number of sheet materials of the same size and specification will be stacked and stored. When in need of use, a certain number of stacked sheet materials will be transferred to the material taking station of the corresponding equipment for placement, facilitating the corresponding equipment to pick up. However, during the transportation or transfer of the stacked sheet materials, some sheet materials are difficult to maintain the initially stacked and neat state, sticking out or tilting from the side, etc., resulting in the inability to ensure the accurate position of the sheet material when the corresponding equipment picks up the sheet material, and there will be a problem of misalignment after picking up the material at an abnormal position. Content of the Utility Model

[0003] The utility model mainly provides a sheet material positioning device to solve the problem that during the transportation or transfer of sheet materials, some sheet materials are difficult to maintain the initially stacked and neat state, sticking out or tilting from the side, etc., resulting in the inability to ensure the accurate position of the sheet material when the corresponding equipment picks up the sheet material, and there will be a problem of misalignment after picking up the material at an abnormal position.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A device for positioning sheet materials, comprising a bin rack on which a material bearing plate is placed. L-shaped positioning plates for limiting the material bearing plate are arranged at three adjacent corners of the bin rack. It further includes an L-shaped mounting plate arranged on a bottom plate. A first pushing mechanism and a second pushing mechanism are arranged on the L-shaped positioning plate, and the pushing directions of the first pushing mechanism and the second pushing mechanism are at 90°. A fixing mechanism for fixing the bin rack is arranged on the bottom plate. Among them, the fact that the pushing directions of the first pushing mechanism and the second pushing mechanism are at 90° means that when they repeatedly impact and push the sheet material protective film, the moving directions are at 90°, that is, they repeatedly impact and push the adjacent sides of the sheet material protective film. A fixing mechanism for fixing the bin rack is arranged on the bottom plate, and any one of the existing technologies can be adopted for this fixing mechanism as long as it can fix the bin rack to the corresponding working position on the bottom plate, so that the bin rack does not move when the first pushing mechanism and the second pushing mechanism are working. For example, the bottom plate and the bin rack are connected by bolts. During use, a certain amount of sheet material protective film is placed on the material bearing plate, and the material bearing plate is placed on the bin rack between the three L-shaped positioning plates. The three L-shaped positioning plates are used to preliminarily limit the material bearing plate. At the same time, after the bin rack and the corresponding components reach the preset position on the bottom plate, the first pushing mechanism and the second pushing mechanism on the L-shaped mounting plate work repeatedly, so as to repeatedly impact and push the sides of the two adjacent sides of the stacked sheet material protective films, so as to adjust the position of the stacked sheet material protective films in cooperation with the L-shaped positioning plates, reset the protruding sheet material protective film, and after all the sheet material protective films are reset, the first pushing mechanism and the second pushing mechanism abut against the two adjacent sides of the stacked sheet material protective films, so as to cooperate with the other three L-shaped positioning plates to achieve positioning. With the structure of the present application, the preliminary positioning and transfer of stacked sheet materials can be realized through the bin rack, the material bearing plate and the L-shaped positioning plate, preventing the sheet materials from toppling and scattering during the transfer; the protruding sheet materials can be reset by repeatedly impacting and pushing the two adjacent sides of the stacked sheet materials through the first pushing mechanism and the second pushing mechanism; at the same time, after resetting, the first pushing mechanism and the second pushing mechanism can cooperate with the three L-shaped positioning plates to achieve the final positioning of the stacked sheet materials, so that the material taking device can accurately take materials, effectively preventing the sheet materials from being misaligned and attached; and compared with the method of manually adjusting the position of the stacked sheet materials, the present application reduces the working intensity and improves the working efficiency.

[0006] Furthermore, the structures of the first pushing mechanism and the second pushing mechanism are the same; the first pushing mechanism includes a positioning cylinder installed on the L-shaped mounting plate, a positioning push plate is arranged at the output end of the cylinder, a positioning guide rod is arranged on the positioning push plate, and a positioning guide hole cooperating with the positioning guide rod is arranged on the L-shaped mounting plate. With this structure, the positioning cylinder can drive the positioning push plate to reciprocate, so that the positioning push plate impacts and pushes the side of the stacked sheet materials.

[0007] Furthermore, a buffer pad is provided on the inner side of the positioning push plate, which can prevent the positioning push plate from directly contacting the sheet material, thereby effectively protecting the sheet material.

[0008] Furthermore, the material receiving plate is provided with a positioning notch matched with the positioning push plate. With this structure, the positioning push plate can avoid collision with the material receiving plate during operation.

[0009] Furthermore, the upper surface area of ​​the material receiving plate is larger than the upper surface area of ​​the single sheet material. The upper surface area of ​​the material receiving plate is larger than the upper surface area of ​​the single sheet material, so that there is a certain space between the sheet material and the surrounding L-shaped positioning plate, thereby reducing the difficulty of placing the sheet material on the material receiving plate, and the staff can directly place it.

[0010] Furthermore, a side baffle is provided on one side of the silo frame to enhance the effect of positioning and limiting the sheet material.

[0011] Beneficial effects: By adopting the structure of the present application, the initial positioning and transfer of stacked sheets can be achieved through the silo rack, the material receiving plate and the L-shaped positioning plate, and the placed sheets will not fall over and scatter during the transfer process; the two adjacent edges of the stacked sheets can be repeatedly impacted and pushed by the first pushing mechanism and the second pushing mechanism, so that the emerged sheets can be reset; at the same time, after the reset, the first pushing mechanism and the second pushing mechanism can be used in conjunction with the three L-shaped positioning plates to achieve the final positioning of the stacked sheets, so that the material picking equipment can accurately pick up the materials; and compared with the method of manually adjusting the position of the stacked sheets, the present application reduces the work intensity and improves the work efficiency.
