Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated sheet metal production technology, and in particular to a sheet metal positioning device. Background Technology
[0002] With the rapid development of the automotive industry, the application of sheet metal stamping parts is increasing, and the sheet metal used is diverse in shape. During production, sheet metal needs to be placed on trolleys for transportation and destacking. Typically, the initial placement of the sheet metal and other equipment on the trolley is determined by either creating sheet metal templates or manually marking lines. Manually installing the sheet metal templates onto the trolley's material rack and then placing the sheet metal according to the templates is problematic. Different shaped sheet metal requires different shaped templates, resulting in significant waste of sheet metal, increased costs, and occupied inventory space. Manual marking requires workers to pre-adjust the sheet metal placement position on the sheet before marking lines, which is time-consuming, inefficient, and prone to confusion when marking too many lines on different shaped sheet metal. Utility Model Content
[0003] This invention aims to overcome the shortcomings of the existing technology by providing a sheet metal positioning device. This device projects the sheet metal's position information onto a trolley rack using a projection device. Workers place the sheet metal and various auxiliary equipment according to the image of the sheet metal's position on the rack. The projection device can be adjusted left and right. Depending on the size of the sheet metal, one, two, or more projection devices can be used to project the sheet metal's position. This image projection method replaces the conventional sheet metal destacking operations that use sheet metal templates for positioning or manual marking, saving sheet metal resources, reducing input costs, eliminating the need for workers to frequently change sheet metal templates or mark lines, reducing workload, and improving automation.

Detailed Implementation
[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0031] like Figure 1-4 As shown, a sheet metal positioning device includes a frame assembly 1, a projector bracket assembly 2, and a projection device 3. The frame assembly 1 is connected to a foundation such as the ground and is fixed in a non-interference position near the trolley. The projector bracket assembly 2 is connected to the upper part of the frame assembly 1, and the projection device 3 is connected to the projector bracket assembly 2. The projection device 3 can move forward and backward and left and right along the projector bracket assembly 2, and the projection angle of the projection device 3 can swing around the installation position, thereby realizing the adjustment of the forward and backward, left and right position and angle of the projection device 3 on the projector bracket assembly 2. There are one or more projection devices 3. Usually, one projection device is arranged above one trolley. When the sheet metal used is large, two projection devices can be used to project simultaneously, depending on the actual production needs.
[0032] The frame assembly 1 includes a left column 4, a right column 5, and a first crossbeam 6, with the two ends of the first crossbeam 6 horizontally supported on the upper ends of the left column 4 and the right column 5, respectively.
[0033] The left column 4, right column 5 and first crossbeam 6 are each provided with multiple wire holes 8, which facilitates the routing of wires from the frame assembly and ensures the reliability and safety of the wires.
[0034] The first crossbeam 6 is connected to the left column 4 and the right column 5 by reinforcing members 7. The reinforcing members 7 can be made of ribbed tubing. The reinforcing members 7 can improve the rigidity of the first crossbeam 6, prevent the first crossbeam 6 from bending and deforming, ensure the accurate position and reliable movement of the projection device 3 on the first crossbeam 6, and avoid situations where the first crossbeam 6 is relatively long and heavy, and the projector bracket assembly 2 is also relatively heavy.
[0035] The left column 4, right column 5, and first crossbeam 6 adopt a square tube structure, which is compact, rigid, strong, reliable, occupies a small area, and does not affect the operation of the trolley.
[0036] The projector bracket assembly 2 includes a first bracket 9, a second crossbeam 10, a second bracket 11, and a mechanical limiter 12. Two first brackets 9 are provided, each connected to a first crossbeam 6. A flange with flange connection holes is provided at the rear end of each first bracket 9. A crossbeam connection hole is also provided on the first crossbeam 6. The first brackets 9 and the first crossbeam 6 are connected by bolts 23, the flange connection holes, and the crossbeam connection holes. The second crossbeam 10 is connected to the two first brackets 9. One end of the second bracket 11 is connected to the second crossbeam 10, and the other end is connected to the projection device 3. The position of the second bracket 11 on the second crossbeam 10 is adjustable.
[0037] The second crossbeam 10 has multiple threaded holes, and the second bracket 11 is connected to the threaded holes on the second crossbeam 10 via a bolt assembly, making the position of the second bracket 11 on the second crossbeam 10 adjustable. The adjustment is relatively simple.
[0038] Alternatively, a guide rail and slider combination structure can be used to achieve adjustable position of the second bracket 11 on the second crossbeam 10. For example, the second crossbeam 10 is equipped with a guide rail, and the second bracket 11 is equipped with a slider that engages with the guide rail. A threaded hole is provided on the slider, and a locking screw is installed in the threaded hole. After the second bracket 11 is adjusted to the predetermined position, the locking screw secures the slider to the guide rail, achieving reliable positioning of the second bracket 11 on the second crossbeam 10. This allows for quick and accurate adjustment and fixation of the projection device 3 to the desired optimal position, suitable for occasions requiring frequent position adjustments.
[0039] The first bracket 9 adopts an adjustable length structure. For example, the first bracket 9 adopts a square tube set structure of different sizes, such as two sections or three sections. The smaller square tube is set inside the larger square tube and can move axially to achieve the adjustment of the overall length. After adjustment, it is locked and fixed. The length is determined according to the installation position of the projection device 3. By changing the length of the first bracket 9, the image projected by the projection device is located on the material rack of the loading area trolley.
[0040] Mechanical limiters 12, such as limit blocks, are provided at both ends of the second crossbeam 10. The mechanical limiters 12 prevent the second support 11 from falling off the end of the second crossbeam 10 during left and right movement.
[0041] The projection device 3 uses a laser scanning projector to form a dynamic image with rapidly moving light spots, so that the human eye sees the complete position image information; other projectors can also be used to directly project the position image onto the desired location. The following describes the main working process of sheet metal destacking using a laser scanning projector as an example, in conjunction with trolley 13, trolley 2 14, and destacking robot 15: The position images of the corresponding guide bars 16 and sheet metal 17 are prepared, and the position images are manually sent to the projection system. The projection system analyzes and processes the position images, causing the laser scanning projector 18 to project dynamic images 19 of the guide bars 16 and sheet metal 17 onto the material rack of trolley 13 in the loading area. Workers place the corresponding guide bars 16 and sheet metal 17 according to the positions of the dynamic images on the rack. The magnetic sheet separator 20 is fixed according to the sheet metal position, and the final material detection device 21 is placed at the bottom of the sheet metal. Trolley 13 drives the sheet metal 17 into the destacking work area, the destacking robot 15 destacking the sheet metal on the material rack of trolley 13, and the laser scanning projector 18 finishes projection. Similar to the steps described above, laser scanning projector 22 projects dynamic images of the guide bars and sheet metal onto the material rack of trolley 2 14. Workers place the guide bars and sheet metal according to the image positions and fix magnetic sheet separation and end-of-life detection devices on the material rack. Trolley 2 moves into the destacking work area, and laser scanning projector 22 finishes projection. After the destacking robot 15 has destacking the sheet metal on trolley 1 13, it can then destacking the sheet metal on trolley 2 14. Trolley 1 13 moves out of the destacking work area, and workers directly place the sheet metal according to the position of the guide bars 16. Trolley 1 13 then drives the sheet metal 17 into the destacking work area.
[0042] This invention can not only locate the position of the sheet material, but also the position of auxiliary equipment such as the material stop bar, magnetic sheet splitter, and end-of-material detection. The device on the trolley rack can be directly installed in place, eliminating the need for debugging the position of the sheet material and various auxiliary equipment, thus improving work efficiency.
