[0002] Stamping equipment is a mechanical device used to stamp metal sheets. It includes punching machines, dies, feeding devices and other components, and processes metal sheets into parts of the required shape through the stamping process. Stamping equipment is widely used in industries such as automobile manufacturing, home appliance manufacturing, aerospace, etc., and is one of the commonly used processing equipment in the field of metal processing.

[0003] At present, stamping is an extremely important link in the production process of metal back panels. Existing stamping equipment, such as the Chinese patent announcement number "CN117884507A", discloses a stamping tool for display metal back panels, which includes an operating table, a sliding table that can move back and forth is installed in the center of the table top of the operating table through a screw drive, and a stamping table for placing the display metal back panel is arranged on the top of the sliding table.

[0004] Since the raw materials for back plate stamping are piled with hundreds of pieces of materials, the oil between the materials will easily cause the two pieces of materials to stick together. When the robot fixture absorbs the materials and puts them on the secondary positioning workbench, if there is no double-sheet abnormality detection, there is a possibility that two pieces of material will be brought into the punching die, causing stamping abnormalities, damage to the punching machine and die, and scrapping of raw materials. Therefore, it is very important to introduce a weighing double-sheet detection device with accurate detection and high sensitivity. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-3 An embodiment of the utility model discloses a weighing type double sheet detection center station, which is arranged between a stamping device 1 and a feeder 2. Specifically, the center station includes a machine table 3, an adjustment plate 4 is arranged on the top of the machine table 3, and a height adjustment mechanism 5 is arranged between the adjustment plate 4 and the machine table 3;

[0025] At least one weighing sensor 6 is arranged above the adjusting plate 4 , a top plate 7 is fixed on the top of the weighing sensor 6 , and a clamping mechanism 8 is also arranged above the top plate 7 .

[0026] In some embodiments, the height adjustment mechanism 5 of the utility model includes a plurality of guide rods 51 fixed to the bottom of the adjustment plate 4, the guide rods 51 are plugged into the top panel 31 of the machine 3, and a locking member for locking the guide rods 51 is provided on the panel 31. In a preferred embodiment, the guide rods 51 of the utility model include an inner rod and an outer rod, and the inner rod and the outer rod are provided on both sides of the frame of the machine 3. The locking member is provided as a bolt threadedly connected to the outside of the panel 31, and the bolt is in conflict with the outer rod to achieve height positioning of the guide rods 51 and achieve height adjustment;

[0027] A limiting plate 52 is also fixed below the guide rods 51. The limiting plate 52 is located below the panel 31. The limiting plate 52 is used to stop the maximum upward sliding position of the guide rods 51. In this embodiment, the guide rods 51 can be connected to the limiting plate 52 by bolt fastening to achieve a detachable effect.

[0028] In some embodiments, in the present invention, four weighing sensors 6 are distributed in a matrix above the adjustment plate 4 , and the top plate 7 is placed above the four weighing sensors 6 .

[0029] Specifically, the clamping mechanism 8 in this embodiment includes a fixed frame 81 symmetrically distributed on the machine table 3, and at least two opposite long-side clamping components 83 and at least one short-side clamping component 82 are provided on the fixed frame 81. Specifically, in this embodiment, each fixed frame 81 is respectively provided with two long-side clamping components 83 and two short-side clamping components 82. Since the two fixed frames 81 adopt a relative structural design, the panel can be clamped and fixed by four long-side clamping components 83 and four short-side clamping components 82.

[0030] On the basis of the above-mentioned embodiment, the long side clamping member 83 in this embodiment has the same structure as the short side clamping member 82;

[0031] Among them, the long side clamping component 83 includes a mounting plate 831 arranged on the fixing frame 81, a cylinder 832 is fixed above the mounting plate 831, and a clamping plate 833 is fixed to the axial end of the cylinder 832. In addition, it should be noted that in this embodiment, a support plate 71 is also fixed to the top of the top plate 7, and the height of the support plate 71 is not less than the height of the clamping mechanism 8. The support plate 71 is used to support the panel. In this embodiment, four support plates 71 are arranged and distributed in a matrix.

[0032] Specifically, in the initial state, the cylinder 832 drives the clamping plate 833 to move outward, and the robot arm takes it and places the panel on the loader 2 on the support plate 71. At this time, the weighing sensor 6 detects the current weight and sets the single-sheet weight range value between D1 and D2. When the weighing value is greater than D2, it is judged as a double-sheet abnormality. In the event of an abnormality, the control unit will issue an alarm to ensure that double-sheet stamping will not damage the punch press and mold, resulting in material loss.

[0033] It should be noted that the fixing frame 81 in the present embodiment includes a transverse profile and a longitudinal profile fixed to each other, a sliding seat slides in the groove of the profile, the mounting plate 831 is connected to the sliding seat by a fastener, and the groove of the profile is a T-shaped structure. Therefore, a T-shaped slider can be used in the present embodiment, and bolts are used as fasteners. This can improve the convenience of installation and disassembly of the mounting plate 831, and facilitate the adjustment of the position of the cylinder 832.

[0034] In addition, the present embodiment also includes an air source processing component 9 and a control box 10. The air source processing component 9 includes an oil-water separator, a solenoid valve, and an air exhaust. The solenoid valve is connected to the air circuit of multiple cylinders 832 through the air exhaust. The clamping mechanism 8 is signal-connected to the control box 10. Specifically, in the present embodiment, a control unit is arranged inside the control box 10, and the solenoid valve and the weighing sensor 6 are electrically connected to the control unit.

[0035] In summary, the utility model adopts the design of the weighing sensor 6, which can achieve 100% detection of double-sheet material grabbing abnormalities after the robot arm picks up the panel and places it on the central station, ensuring that double-sheet stamping will not damage the punch press and the mold, causing material loss. At the same time, the top plate 7 in the utility model is adjusted by the height adjustment mechanism 5, which can further meet the height adaptation requirements of the stamping equipment 1 and the loader 2. The overall structural design is simple, which greatly optimizes the current stability and yield rate of panel stamping.
