Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, specifically to a multi-point positioning lifting feeding device. Background Technology
[0002] In the process of transferring sheet-like workpieces, it is necessary to stack the sheet-like workpieces while ensuring the stability of their position in the stacked state. Therefore, depending on the shape and size of the sheet-like workpieces, different clamping and positioning devices need to be purchased to achieve stacking and positioning of the sheet-like workpieces. However, the existing clamping and positioning devices have limited functions and cannot adapt to sheet-like workpieces of different shapes and sizes. Enterprises need to purchase a large number of clamping and positioning devices, which increases the enterprise's procurement costs.
[0003] In addition, the height of the stacked workpieces will decrease with each pick-up. In order to adapt to the continuously decreasing pick-up height, the picking robot also needs to constantly adjust its picking position. This adaptation of the robot to the decreasing pick-up height will lengthen the picking path. At the same time, the robot path adjustment also takes a certain amount of time. Therefore, how to improve the picking efficiency of stacked sheet workpieces is also a problem that this technical solution needs to solve. Utility Model Content
[0004] The purpose of this invention is to provide a multi-point positioning lifting and feeding device to solve at least one of the aforementioned problems in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-point positioning lifting and feeding device includes a fixed plate and positioning columns. The fixed plate is symmetrically provided with strip-shaped mounting hole units. Each strip-shaped mounting hole unit includes multiple strip-shaped mounting holes extending toward the center of the fixed plate. The number of positioning columns corresponds one-to-one with the number of strip-shaped mounting holes. The lower end of each positioning column can be adjusted to adjust its installation position along the length of the strip-shaped mounting hole.
[0007] A lifting plate is provided above the fixed plate. The lifting plate is used to support stacked sheet-like workpieces. The lifting plate is symmetrically provided with strip-shaped hole units. Each strip-shaped hole unit includes multiple strip-shaped holes extending toward the center of the lifting plate. The extension trajectory of the strip-shaped holes coincides with the extension trajectory of the strip-shaped mounting holes in the vertical direction. The positioning posts extend upward and pass through the corresponding strip-shaped holes directly above. Multiple positioning posts extend out of the upper end of the lifting plate to limit the stacked sheet-like workpieces on the lifting plate in the horizontal direction. During the lifting process, the height position of the stacked sheet-like workpieces is adjusted.
[0008] In this technical solution, multiple positioning posts correspond one-to-one with the number of strip-shaped mounting holes. That is, one positioning post is installed in each strip-shaped mounting hole. The lower end of the positioning post is adjusted along the length of the strip-shaped mounting hole, providing guidance for the horizontal movement of the positioning post. This allows for convenient and quick adjustment of the positioning post's position to accommodate horizontal limiting of stacked sheet-like workpieces of different shapes and sizes. Since a lifting plate is located above the fixed plate to support the stacked sheet-like workpieces, the installation position of the positioning posts needs to be adjusted according to the shape and size of the sheet-like workpieces on the lifting plate. During the adjustment of the positioning post's installation position, the position of the positioning post within the strip-shaped mounting hole is also adjusted, allowing multiple positioning posts extending from the upper end of the lifting plate to horizontally limit the stacked sheet-like workpieces on the lifting plate. Furthermore, because the lifting plate can move up and down, the overall height of the stacked sheet-like workpieces in the horizontally limited state can be adjusted to accommodate the picking height of the material handling robot in the next process, thereby improving the material handling robot's efficiency in handling sheet-like workpieces.
[0009] Furthermore, in order to accommodate a variety of sheet-like workpiece shapes and sizes, the strip-shaped mounting hole unit includes three strip-shaped mounting holes: a left strip-shaped mounting hole, a middle strip-shaped mounting hole, and a right strip-shaped mounting hole. The middle strip-shaped mounting hole extends horizontally, and the left and right strip-shaped mounting holes are symmetrically arranged on both sides of the middle strip-shaped mounting hole. The distance between the left and right strip-shaped mounting holes gradually decreases from the outer end of the fixing plate inward.
[0010] Furthermore, in order to accommodate a variety of sheet-like workpiece shapes and sizes, the inner ends of the left and right strip-shaped mounting holes are both located on a first circular trajectory, and the inner ends of the middle strip-shaped mounting holes are both located on a second circular trajectory, with the radius of the first circular trajectory being smaller than the radius of the second circular trajectory; the outer ends of the left and right strip-shaped mounting holes are both located on a third circular trajectory, and the outer ends of the middle strip-shaped mounting holes are both located on a fourth circular trajectory, with the radius of the third circular trajectory being smaller than the radius of the fourth circular trajectory.
[0011] Furthermore, in order to achieve a smoother driving of the lifting plate, it also includes a lifting drive device, a drive plate, and multiple guide columns. The drive plate is located below the fixed plate, and the fixed plate is provided with multiple guide holes. The multiple guide columns slide vertically with the corresponding guide holes. The lifting plate is fixed at the upper end of the multiple guide columns, and the drive plate is fixed at the lower end of the multiple guide columns. The lifting drive device drives the lifting plate to rise and fall through the drive plate.
[0012] Furthermore, in order to improve the stability of the lifting plate, guide holes are provided at the four corners of the fixed plate.
[0013] Furthermore, in order to achieve more precise driving of the lifting plate, the lifting drive device is a lead screw motor. The lead screw of the lead screw motor is threadedly connected to the drive plate, and the upper end of the lead screw of the lead screw motor is rotatably connected to the fixed plate. In order to ensure the smoothness of the lead screw transmission, the upper end of the lead screw of the lead screw motor is rotatably connected to the fixed plate through a bearing.
[0014] Furthermore, it also includes a through-beam sensor and a reflective fiber optic sensor. The two through-beam sensors are located on both sides of the lifting plate and are used to detect the rising position of the lifting plate. The reflective fiber optic sensor is installed on the lifting plate and is used to detect whether there is a sheet-like workpiece on the lifting plate.
[0015] Furthermore, in order to better match the mounting base with the strip-shaped mounting hole, a strip-shaped stepped groove is provided in the strip-shaped mounting hole, and a mounting base is provided at the lower end of the positioning column. The mounting base slides in conjunction with the strip-shaped stepped groove, and the mounting base is fixedly installed in the strip-shaped mounting hole by screws and nuts.
[0016] Furthermore, to facilitate the handling of sheet-like workpieces, the upper end of the positioning post is tapered, and handles are symmetrically provided on both sides of the fixing plate.
[0017] Furthermore, to make it easier for operators to adjust the product according to different sizes, a scale is provided on one side of the strip mounting hole.
[0018] The beneficial effects of this utility model are as follows: In this technical solution, since the number of positioning posts corresponds one-to-one with the number of strip-shaped mounting holes, that is, one positioning post is installed in each strip-shaped mounting hole. The lower end of the positioning post is adjusted along the length of the strip-shaped mounting hole to change its installation position. The strip-shaped mounting hole provides guidance for the horizontal movement of the positioning post, allowing for convenient and quick adjustment of the positioning post's installation position to adapt to the horizontal limiting of stacked sheet-like workpieces of different shapes and sizes. Because a lifting plate is provided above the fixed plate, which is used to support the stacked sheet-like workpieces, the installation position of the positioning posts needs to be adjusted according to the shape and size of the sheet-like workpieces on the lifting plate. During the adjustment of the positioning post's installation position, the position of the positioning post within the strip-shaped mounting hole is also adjusted, allowing multiple positioning posts extending from the upper end of the lifting plate to limit the horizontal movement of the stacked sheet-like workpieces on the lifting plate. Furthermore, since the lifting plate can rise and fall, the overall height of the stacked sheet-like workpieces in the horizontal limiting state can be adjusted to adapt to the picking height of the picking robot in the next process, thereby improving the picking efficiency of the picking robot for sheet-like workpieces.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0029] Example 1:
[0030] like Figures 1-8As shown, this embodiment provides a multi-point positioning lifting and feeding device, including a fixed plate 1 and positioning columns 2. The fixed plate 1 is symmetrically provided with strip-shaped mounting hole units. The strip-shaped mounting hole units include multiple strip-shaped mounting holes 3 extending toward the middle of the fixed plate 1. The number of positioning columns 2 corresponds one-to-one with the number of strip-shaped mounting holes 3. The lower end of the positioning column 2 is adjusted to the installation position along the length direction of the strip-shaped mounting holes 3.
[0031] A lifting plate 4 is provided above the fixed plate 1. The lifting plate 4 is used to support the stacked sheet workpieces 6. The lifting plate 4 is symmetrically provided with strip hole units. The strip hole units include multiple strip holes 5 extending toward the middle of the lifting plate 4. The extension trajectory of the strip holes 5 coincides with the extension trajectory of the strip mounting holes 3 in the vertical direction. The positioning pins 2 extend upward and pass through the corresponding strip holes 5 directly above. The multiple positioning pins 2 extend out of the upper end of the lifting plate 4 to limit the stacked sheet workpieces 6 in the horizontal direction. During the lifting process, the height position of the stacked sheet workpieces 6 is adjusted.
[0032] In this technical solution, since the number of positioning posts 2 corresponds one-to-one with the number of strip mounting holes 3, that is, one positioning post 2 is installed in each strip mounting hole 3. The lower end of the positioning post 2 is adjusted along the length of the strip mounting hole 3 to adjust its installation position. The strip mounting hole 3 provides guidance for the horizontal movement of the positioning post 2, which can be easily and quickly adjusted to adapt to the horizontal limiting of stacked sheet workpieces 6 of different shapes and sizes. Since a lifting plate 4 is provided above the fixing plate 1, the lifting plate 4 is used to support the stacked sheet workpieces 6. The installation position of the positioning post 2 needs to be adjusted according to the shape and size of the sheet workpieces 6 on the lifting plate 4. During the adjustment of the installation position of the positioning post 2, the position of the positioning post 2 in the strip mounting hole 3 is also adjusted, so that multiple positioning posts 2 extending from the upper end of the lifting plate 4 can limit the stacked sheet workpieces 6 on the lifting plate 4 in the horizontal direction. Since the lifting plate 4 can be raised and lowered, the overall height of the stacked sheet workpieces 6 in the horizontal limit state can be adjusted to adapt to the picking height of the picking robot in the next process, thereby improving the picking efficiency of the picking robot on the sheet workpieces 6.
