[0037] The present application provides a blanking mechanism which can flip and then blank the workpiece.

[0038] In combination Figures 1 to 3 A blanking mechanism includes a transmission assembly 100, a flipping assembly 200 and a blanking assembly (not marked in the figure). The flipping assembly 200 is used to flip the workpiece 600 on the transmission assembly 100, and the blanking assembly is used to blank the workpiece 600 on the flipping assembly 200 to blank the workpiece 600 after flipping.

[0039] The transmission assembly 100 is used to transmit the workpiece 600 to be blanked. For example, in an embodiment, the transmission assembly 100 can be connected to the previous process to receive the workpiece 600 processed by the previous process, and the workpiece 600 is transmitted. The transmission assembly 100 can be a conveyor belt.

[0040] The flipping assembly 200 includes a material taking structure 210, a rotary driving structure 220 and a lifting driving structure 230.

[0041] The taking structure 210 is arranged above the conveying assembly 100, and is used for taking the workpiece 600 on the conveying assembly 100. The taking structure 210 can be a suction structure or a gripper structure.

[0042] The rotating driving structure 220 is drivingly connected with the taking structure 210, so that the taking structure 210 can drive the workpiece 600 to rotate. For example, the rotating driving structure 220 can drive the taking structure 210 to rotate by 180°, so as to realize the turnover of the workpiece 600.

[0043] The lifting driving structure 230 is drivingly connected with the rotating driving structure 220, so that the rotating driving structure 220 can drive the taking structure 210 to approach or move away from the conveying assembly 100. Specifically, when the workpiece 600 is turned over, the lifting driving structure 230 can drive the taking structure 210 to descend to the workpiece 600 on the conveying assembly 100 through the rotating driving structure 220, and after the taking structure 210 takes the workpiece 600, the lifting driving structure 230 can drive the taking structure 210 to ascend to a safe height through the rotating driving structure 220, and then the rotating driving structure 220 can drive the taking structure 210 to rotate, so as to realize the turnover of the workpiece 600.

[0044] The discharging assembly is movably arranged at one side of the taking structure 210, and is used for discharging the workpiece 600 on the taking structure 210. Specifically, after the taking structure 210 turns over the workpiece 600, the discharging assembly can move to the taking structure 210 to take and discharge the workpiece 600 on the taking structure 210. The discharging assembly can be a robot or a multi-dimensional moving mechanical hand.

[0045] As can be seen, in the discharging mechanism, the taking structure 210 of the turnover assembly 200 is arranged above the conveying assembly 100. After the conveying assembly 100 conveys the workpiece 600 below the taking assembly, the lifting driving structure 230 can drive the taking structure 210 to descend to take the workpiece 600 on the conveying assembly 100 through the rotating driving structure 220. After the taking is completed, the lifting driving structure 230 can drive the taking structure 210 to ascend to a safe height, and the rotating driving structure 220 drives the taking structure 210 to rotate at the safe height, so as to turn over the workpiece 600. After the taking structure 210 turns over the workpiece 600, the discharging assembly can move to the taking structure 210 to take and discharge the workpiece 600 on the taking structure 210, so as to realize the turnover and discharging of the workpiece 600. This method can realize the turnover and discharging of the workpiece 600, and has high efficiency.

That is, the suction direction of the first suction accessory 212 and the suction direction of the second suction accessory 213 can form an angle of 180°.

[0047] It can be understood that when the suction directions of the first suction accessory 212 and the second suction accessory 213 are opposite, in an initial state, if the first suction accessory 212 on the mounting member 211 faces downward and the second suction accessory 213 faces upward, the lifting driving structure 230 can drive the first suction accessory 212 on the mounting member 211 to move downward to suck the workpiece 600 on the conveying assembly 100, the first suction accessory 212 sucks the workpiece 600, and after the lifting driving structure 230 drives the first suction accessory 212 on the mounting member 211 to lift the workpiece 600 to a safe height, the rotating driving structure 220 can drive the first suction accessory 212 on the mounting member 211 to overturn the workpiece 600 by 180°, so as to realize the turning of the workpiece 600, and at this time, the first suction accessory 212 is in an upward state, and the second suction accessory 213 is in a downward state. When the workpiece 600 on the first suction accessory 212 is unloaded by the unloading assembly, the lifting driving structure 230 can directly drive the second suction accessory 213 on the mounting member 211 to move downward to suck the workpiece 600 on the conveying assembly 100, and there is no need to overturn again. This mode can save one overturning step, so as to improve the unloading efficiency of the unloading mechanism.

Alternatively, a part of the extension arms 2142 in each set of connecting members 214 can be used to mount the first suction member 212, and the other part of the extension arms 2142 in each set of connecting members 214 can be used to mount the second suction member 213.

[0051] In an embodiment, in order to avoid interference between the first suction member 212 and the second suction member 213 for installation, the extension arms 2142 can be arranged staggered along the length direction of the connecting rod 2141, and the extension arms 2142 can be respectively located on both sides of the connecting rod 2141.

[0052] Further, the connecting rod 2141 and the extension arm 2142 can be connected through a first clamp 2143. The extension arm 2142 and the first suction member 212 and the second suction member 213 can be connected through a second clamp 2144.

[0053] It can be understood that the above structure is connected through the first clamp 2143 and the second clamp 2144 respectively, which can facilitate the connection between the connecting rod 2141 and the extension arm 2142, and at the same time can facilitate the adjustment of the angle between them, so as to facilitate the adjustment of the angle of the first suction member 212 and the second suction member 213, and the same can facilitate the connection between the first suction member 212 and the second suction member 213 and the second extension arm 2142 respectively, and at the same time facilitate the adjustment of the angle between them, thereby ensuring the suction angle of the first suction member 212 and the second suction member 213.

[0054] In addition, in an embodiment, in order to improve the stability of the material taking structure 210 taking material, and enable the material taking structure 210 to simultaneously suck multiple workpieces 600 or workpieces 600 with larger area and mass, the mounting member 211 can be further provided with multiple avoiding holes 215, and each avoiding hole 215 can be provided with at least one set of first suction member 212 and second suction member 213, for example, each avoiding hole 215 can be provided with one set, two sets or three sets of first suction member 212 and second suction member 213 respectively.

[0055] Referring to Figure 4 , the first suction member 212 and the second suction member 213 can each include a suction disc 2121 and an elastic tube 2122, the suction disc 2121 is in communication with the elastic tube 2122, and the elastic tube 2122 is connected with the extension arm 2142.

[0056] Specifically, the elastic tube 2122 can introduce negative pressure gas into the suction cup 2121 on one hand, and the suction cup 2121 can play a buffering role when adsorbing the workpiece 600 on the other hand.

[0057] Referring to Figure 1 The blanking mechanism can further include support columns 300 located on both sides of the transmission assembly 100, and each support column 300 is provided with a support seat 400.

[0059] For example, one end of the mounting piece 211 of the taking structure 210 can be drivingly connected with the rotary driving structure 220, and the other end of the mounting piece 211 can be rotationally connected with the support seat 400 without the rotary driving structure 220, such as being rotationally connected with the support seat 400 through a rotating shaft.
