The automatic punching machine 1 adopts a common punching machine, that is, with a related sensor. When the clamp 5 clamps the basin frame 10, the sensor will generate a signal to the automatic punching machine 1, and the automatic punching machine 1 realizes punching. This technology is relatively conventional, so I will not go into too much detail. ; When the basin rack 10 comes out of the shaping machine, it will be directly transported to the vicinity of the automatic punching machine 1 through the feeding conveyor belt, and then the loading robot will transfer the basin rack 10 in the feeding conveyor belt to the fixture 5, and then the automatic punching machine 1 will start and punch the basin rack 10. After punching, the basin rack 10 will be transferred to the discharging conveyor belt 4 through the unloading robot 2 for unloading, and then the loading robot will continue to transfer the basin rack 10 in the feeding conveyor belt to the fixture 5 for punching the next basin rack 10.

The loading manipulator includes a support block fixedly connected to the workbench 3, a rotating cylinder 7 fixedly connected to the support block, and a rotating rod 14 fixedly connected to the output end of the rotating cylinder 7. The end of the rotating rod 14 is fixedly connected to the first cylinder 11, and the output end of the first cylinder 11 is fixedly connected to an inner cylinder for adsorbing the basin rack 10. The suction cup at the bottom and the first cylinder 11 are located above the fixture 5. When the basin rack 10 needs to be transferred, the rotating cylinder 7 is started, thereby moving the first cylinder 11 to directly above the basin rack 10 on the feed conveyor belt, and then the first cylinder 11 is started, the suction cup moves down and sucks the basin rack 10, and then the first cylinder 11 is reversely ventilated to lift the basin rack 10 and make the bottom of the basin rack 10 higher than the top of the vertical plate 12, and then the rotating cylinder 7 is started to transfer the basin rack 10 to above the fixture 5, and then the first cylinder 11 is started to place the basin rack 10 in the fixture 5, and then the suction cup is cut off, and then the first cylinder 11 is reversely ventilated, and then the rotating cylinder 7 is reversely ventilated, thereby turning the first cylinder 11 to above the feed conveyor belt, and now the automatic punching machine 1 can be started to punch the basin rack 10.

[0022] In this embodiment, the clamp 5 includes a profiling block 29 embedded in the outer contour of the basin frame 10, and the profiling block 29 is provided with an elastic clamping mechanism 6 for clamping the basin frame 10. The top of the profiling block 29 is provided with a first punching hole aligned with the mounting hole 28 of the basin frame 10, and the middle of the basin frame 10 and the profiling block 29 are provided with an aligned notch 16. The profiling block 29 is fixed with a support frame 26, and the elastic clamping mechanism 6 includes a boss 17 fixed to the support frame 26, a guide rod 21 passing through the boss 17, and a guide rod 21 fixed to the support frame 26. The limit block 27 on the guide rod 21 passes through the notch 16 and is attached to the bottom of the notch 16. The limit block 27 is connected to the output end of the second cylinder 18 fixed to the boss 17. Therefore, when it is embedded in the contour block 29, the second cylinder 18 is started, thereby driving the limit block 27 to move, thereby inserting the limit block 27 into the notch 16 and clamping the basin frame 10 5; and a spring 23 is provided on the outer circle of the guide rod 21. The spring 23 is located between the boss 17 and the limit block 27. The support frame 26 is provided with a notch 15, the limit block 27 is provided with a protrusion 34 passing through the notch 15, the protrusion 34 is provided with a through hole, the output end of the second cylinder 18 is in clearance with the through hole, the output end of the second cylinder 18 passing through the through hole is provided with a first limit platform, the protrusion 17 is provided with a limit cylinder 20, the guide rod 21 is in clearance with the limit cylinder 20, and the end of the guide rod 21 away from the limit block 27 is provided with a second limit platform 19, wherein the limit block 27 is provided with a chamfer, so when the basin frame 10 moves down to the chamfer When the basin rack 10 is in the position, the limit block 27 squeezes the spring 23. When the basin rack 10 moves to the specified position, the basin rack 10 is aligned with the notch 16 in the profiling block 29. At this time, the limit block 27 pops out under the action of the spring 23 and limits the basin rack 10. When the unloading robot 2 takes out the basin rack 10, the second cylinder 18 is started to pull the limit block 27 out of the notch 16. When the basin rack 10 is taken out, the second cylinder 18 is reset, and the limit block 27 is reinserted into the notch 16 of the profiling block 29 under the action of the spring 23.A support platform 22 is provided on the workbench 3. The upper part of the support platform 22 is in close contact with the bottom plate of the basin frame 10. A second punching hole 32 is provided on the upper part of the support platform 22 and is aligned with the riveting hole 30 of the basin frame 10. The basin frame 10 is made of magnetic material. An adjusting column 31 is rotatably connected to the support platform 22. The top of the adjusting column 31 is fixed with a ring-shaped electromagnet 33 that can adsorb the bottom of the basin frame 10. A motor 24 is provided on the workbench 3. A gear 25 is fixed to the output end of the motor 24. An outer gear ring is provided on the outer circle of the adjusting column 31 that meshes with the gear 25. Since the profiling block 29 is not always aligned with the notch 16 in the basin frame 10 Therefore, when the two notches 16 are offset, the stopper 27, under the action of the spring 23, presses against the side wall of the basin frame 10. At this time, the annular electromagnet 33 is energized and firmly attracts the bottom of the basin frame 10. The motor 24 then starts, causing the gear 25 to rotate, driving the adjustment column 31, thereby driving the annular electromagnet 33 and, in turn, the basin frame 10. When the profiling block 29 is aligned with the notch 16 in the basin frame 10, the stopper 27, under the action of the spring 23, simultaneously penetrates the notch 16 of the basin frame 10 and the profiling block 29, thereby achieving accurate positioning of the basin frame 10. At this point, the automatic punching machine 1 can be started.

[0023] Working principle: After the basin rack 10 comes out of the shaping machine, it will be directly transported to the vicinity of the automatic punching machine 1 through the feeding conveyor belt, and then the rotating cylinder 7 in the feeding robot will be started, thereby moving the first cylinder 11 to the top of the basin rack 10 on the feeding conveyor belt, and then the first cylinder 11 will be started, the suction cup will move down and suck the basin rack 10, and then the first cylinder 11 will be ventilated in the reverse direction to lift the basin rack 10 and make the bottom of the basin rack 10 higher than the top of the vertical plate 12, and then the rotating cylinder 7 will be started to transfer the basin rack 10 to the top of the clamp 5, and then the first cylinder 11 will be started to put the basin rack 10 into the clamp 5. When the frame 10 moves down to the chamfer, the limit block 27 will squeeze the spring 23 and move outward. When the basin frame 10 is in contact with the annular permanent magnet and the top of the support platform 22, the limit block 27 presses the side wall of the basin frame 10 under the action of the spring 23. Then the annular permanent magnet is energized and sucks the basin frame 10 tightly. Then the suction cup is cut off. Then the first cylinder 11 is ventilated in the reverse direction. Then the rotating cylinder 7 is ventilated in the reverse direction, thereby turning the first cylinder 11 to the top of the feed conveyor belt. Then the motor 24 is started, the gear 25 will rotate and drive the adjusting column 31 to rotate, thereby driving the annular electromagnet 33 to rotate, and then driving the basin frame 10 to rotate. Rotate, when the profiling block 29 is aligned with the notch 16 in the basin frame 10, the limit block 27 will penetrate the notch 16 of the basin frame 10 and the profiling block 29 at the same time under the action of the spring 23, thereby realizing the accurate positioning of the basin frame 10, and then the annular permanent magnet and the motor 24 are powered off, and then the automatic punching machine 1 is turned on to punch the basin frame 10. After punching, the rotary cylinder 7 in the blanking robot 2 is started, thereby moving the first cylinder 11 to the position above the clamp 5, and then the second cylinder 18 is started to pull the limit block 27 out of the notch 16; then the first cylinder 11 is started, the suction cup moves down and sucks the basin frame 10 Take it, then the first cylinder 11 reverses the ventilation, lifts the basin rack 10 and makes the bottom of the basin rack 10 higher than the top of the clamp 5, then the rotating cylinder 7 is started, and the basin rack 10 is transferred to the top of the discharge conveyor belt 4, then the first cylinder 11 is started, and the basin rack 10 is placed on the discharge conveyor belt 4 for unloading, and then the loading robot continues to transfer the basin rack 10 in the feed conveyor belt to the clamp 5 for punching the next basin rack 10. Therefore, the present invention eliminates the previous situation of low efficiency and high labor cost when manually placing the basin racks 10 one by one in the punching machine for punching by automatic punching of the basin racks 10.
