Description

Technical Field

[0001] The utility model belongs to the technical field of stamping feeding, and in particular relates to automatic stamping feeding equipment. Background Art

[0002] When stamping aluminum shells for laptop computers and tablets, each existing workstation is manually loaded and unloaded, that is, workers place the aluminum sheets one by one on the mold corresponding to the stamping equipment, and then take out the finished products after stamping them one by one for the next stamping process. In this process, due to manual loading and unloading, there are technical problems such as high labor intensity and low loading and unloading efficiency. In order to reduce production costs and improve loading efficiency, in the prior art, the aluminum sheets are stacked and then separated by a sheet separation mechanism, and then the suction cup assembly of a handling module such as a robotic arm transports the single aluminum sheet to the mold corresponding to the stamping equipment to complete the stamping. Since there are multiple stamping processes when processing aluminum shells for laptop computers and tablets, it is particularly important for the first punch press to automatically load the sheets.

[0003] The automatic feeding in the existing technology has the following technical problems: 1. There is a small probability of overlapping materials after the sheet separation mechanism realizes the separation, and when the stacked aluminum sheet is moved to the mold for stamping, it will cause damage to the mold; 2. The existing automatic feeding equipment for aluminum sheets has a relatively simple structure and a low level of automation. Most of them only use a lifting module to lift the stacked aluminum sheets and a sheet separation mechanism to separate the aluminum sheets. It lacks functions such as positioning the aluminum sheets and detecting overlapping materials. Utility Model Content

[0044] See also Figure 8 , 9 As shown, the feed module 2 includes a bottom plate 21 fixedly connected to the lower part of the frame 1 by bolts, a feed conveying mechanism arranged on the bottom plate 21, and a feed platform 22 fixedly connected to the moving part of the feed conveying mechanism. Specifically, the feed conveying mechanism includes a feed motor 23, a feed screw 24 driven by the feed motor 23 and rotatably connected to the bottom plate 21, a feed slider (not shown in the figure) is engaged with the feed screw 24, and the feed platform 22 is fixedly connected to the feed slider by bolts. That is, the feed platform 22 is horizontally moved by the existing screw transmission mechanism, and the stacked aluminum sheets are placed on the feed platform 22.

[0045] See also Fig.10 As shown, the feeding module 3 includes a vertical plate 31 fixedly connected to the frame 1 on one side of the feeding module 2 by bolts, a feeding conveying mechanism arranged on the vertical plate 31, and a feeding platform 32 fixedly connected to the moving part of the feeding conveying mechanism.

In addition, in order to make the feeding platform 32 slide smoothly in the longitudinal direction, the feeding platform 32 slides up and down relative to the vertical plate 31 through a slide rail slider structure.

[0046] See also Figure 1 , 3 As shown, two centering cylinders 11 are horizontally fixedly connected to the frame 1 on the left and right sides of the feeding module 2, and an L-shaped baffle 12 is fixedly installed on the guide rod of the centering cylinder 11, and the baffle 12 includes a vertical baffle arranged parallel to the feeding screw 24 and a horizontal baffle arranged perpendicular to the feeding screw 24.

The slicing frame 45 is rotatably connected in the guide block 412 through a ball joint structure or a pin structure. When the guide rod of the slicing cylinder 44 extends, the slicing frame 45 is driven to abut against the stacked aluminum sheet.

In order to guide the aluminum sheet when it is pushed out, the upper end surface of the frame 1 on both sides of the sheeting cylinder 44 is fixedly connected with side push plates 43 by bolts, and the push plates 43 on both sides are arranged opposite to each other.

[0050] See also Figure 5 As shown, the positioning weighing module is arranged opposite to the material distribution module 4 and includes a weighing module 5 and a positioning module 6 arranged on the upper end surface of the frame 1. Specifically, the weighing module 5 includes a weighing sensor 51 and a weighing controller 52 fixedly connected to the frame, and a weighing platform 53 arranged on the weighing sensor 51. Furthermore, a proximity sensor 54 is embedded on the weighing platform 53.

[0051] The positioning module 6 includes a positioning reference block 61 fixedly connected to the weighing platform by bolts, a positioning cylinder 62 fixedly connected to the upper end surface of the frame 1 opposite to the positioning reference block 61 by bolts, and a push block 63 fixedly connected to the guide rod of the positioning cylinder 62. The two groups of positioning reference blocks 61 are respectively arranged opposite to the two positioning cylinders 62, so that when the guide rod of the positioning cylinder 62 is extended, the aluminum sheet is pushed to abut against the positioning reference block 61, thereby performing secondary positioning on the aluminum sheet.

[0052] See also Figure 4As shown, the transport module 7 is arranged on the upper end surface of the frame 1 on one side of the material distribution module 4 and includes a transport conveying mechanism, a transport frame 71 arranged on the moving part of the transport conveying mechanism, upper and lower cylinders 72 fixedly connected vertically downward by bolts on the transport frame 71, and a mounting plate 73 fixedly connected to the guide rods of the upper and lower cylinders 72, four suction cup assemblies 74 fixedly installed on the mounting plate 73 by bolts, the suction cup assembly 74 is connected to the air suction assembly, and the suction cup assembly 74 adsorbs the aluminum sheet through the air suction assembly.

[0054] The working process of the utility model is as follows:

[0055] The stacked aluminum sheets are placed manually or by machine on the feeding platform 22 and pushed to make them abut against the horizontal baffle. The controller controls the guide rod of the centering cylinder 11 to extend so that the vertical baffle is abutted against the aluminum sheets, thereby completing the centering and initial positioning of the stacked aluminum sheets. The controller controls the guide rod of the centering cylinder 11 to retract, and controls the feed motor 23 to rotate so that the feeding platform 22 moves toward the feeding module 3. The controller controls the feeding motor 33 to rotate so that the feeding platform 32 lifts the stacked aluminum sheets to the dividing module 4. The controller controls the guide rod of the sheeting cylinder 44 to extend to separate the aluminum sheets, and then the guide rod of the pushing cylinder 42 extends to push out the single sheet of aluminum sheets. The controller controls the transport motor 76 to rotate to drive the suction cup assembly 74 moves to the top of the pushed out aluminum sheet, the guide rods of the upper and lower cylinders 72 extend out, and the aluminum sheet is adsorbed through the air suction assembly and the suction cup assembly 74, and the guide rods of the upper and lower cylinders 72 retract to drive the aluminum sheet to rise, and then the aluminum sheet is transferred to the weighing platform 53. If the detection result of the weighing sensor 51 is a single sheet of aluminum sheet, the controller controls the guide rod of the positioning cylinder 62 to extend to re-position the aluminum sheet. If the detection result of the weighing sensor 51 is a stacked material, an instruction is sent to the controller through the weighing controller 52 to suspend subsequent actions and issue an alarm; in the above process, by controlling the rotation of the feeding motor 33, the top layer of aluminum sheet is always at the same height, so that the sheet separation operation of the material separation module 4 is convenient.

[0056] It should be noted that the controller can use an existing PLC controller, and its connection method and control principle with components such as the centering cylinder 11, the feed motor 23, the feeding motor 33, the ejection cylinder 42, the slicer cylinder 44, the weighing module 5, the positioning cylinder 62, and the conveying module 7 are existing technologies. As long as the above process can be achieved, it will not be repeated here.
