[0022] Embodiment: As Figures 1-4As shown in the figure, a turnover unloading mechanism for a bending machine comprises a rack 100, a jacking unit 200, a support frame 300 and a rotating unit 400. The jacking unit 200 is fixedly installed on the rack 100. The support frame 300 is connected to the jacking unit 200 and movably installed on the rack 100. The jacking unit 200 can drive the support frame 300 to move up and down along the rack 100. The rotating unit 400 comprises a hollow rotating platform 410 and a suction cup 420 installed on the hollow rotating platform 410. The hollow rotating platform 410 is fixedly installed on the support frame 300. The hollow rotating platform 410 can drive the suction cup 420 to rotate. The suction cup 420 is used to suck the product. The hollow rotating platform 410 has the characteristics of high working efficiency, high precision and high rigidity. It adjusts the angle of the product through motor driving and is applied to various rotary motion occasions. In this application, the rack 100 is used to support the jacking unit 200 and the support frame 300. The support frame 300 is used to support the rotating unit 400. During operation, the jacking unit 200 drives the support frame 300 and the rotating unit 400 to move up and down to adjust the height of the rotating unit 400 until the suction cup 420 is just attached to the product on the carrier. Then the suction cup 420 sucks the product. Then the jacking unit 200 drives the rotating unit 400 to move, so that the product is separated from the carrier and reaches the unloading height. The hollow rotating platform 410 drives the suction cup 420 and the product to turn over, so that the product reaches the unloading position. The suction cup 420 is vacuumized to release the product. In this application, the cooperation between the jacking unit 200 and the rotating unit 400 realizes the transfer of the product from the carrier to the unloading position. The hollow rotating platform 410 is selected to turn over the product, which ensures the accuracy and repeatability of the turnover and reduces the error of the unloading position of the product, thereby improving the yield of the product.
[0023] As shown in the figure, Figure 1 and Figure 2 As shown in the figure, the suction cup 420 is arranged vertically to the hollow rotating platform 410. A plurality of suction nozzles 421 are arranged on the suction cup 420. The suction nozzles 421 are connected to a vacuum generator 110. The vacuum generator 110 is fixedly installed on the rack 100. A photoelectric sensor 411 is fixedly installed on the hollow rotating platform 410.
[0024] As shown in the figure, Figure 1 The suction cup 420 is installed on the hollow rotating platform 410 in the horizontal direction. A plurality of suction nozzles 421 are installed on the suction cup 420. The suction nozzles 421 are located below the suction cup 420. The suction nozzles 421 are connected to the vacuum generator 110 through pipelines. When the vacuum generator 110 operates, the suction nozzles 421 suck the product. The photoelectric sensor 411 assists the hollow rotating platform 410 in positioning, further improving the rotation accuracy and repeatability of the hollow rotating platform 410.
[0025] As Figure 1 shown, the support frame 300 comprises a support plate 320 and a sliding plate 310 fixedly installed on the support plate 320, the sliding plate 310 is slidingly installed on the rack 100, and the hollow rotating platform 410 is fixedly installed on the support plate 320.
[0026] Two parallel sliding plates 310 are fixedly installed on the support plate 320, and the rack 100 is provided with guide rails 120 arranged in the vertical direction, and the sliding plates 310 are slidingly installed on the guide rails 120. The lower surface of the support plate 320 is fixedly installed with two sliding plates 310, the hollow rotating platform 410 is fixedly installed on the upper surface of the support plate 320, and the rack 100 is fixedly provided with two parallel guide rails 120, the two sliding plates 310 are respectively clamped into the two guide rails 120, and the two sliding plates 310 are located on the outer side of the rack 100. By cooperating the sliding plate 310 and the guide rail 120 on the rack 100, the stability and the position accuracy of the support frame 300 during operation can be improved.
[0027] As Figure 1 and Figure 3 shown, the jacking unit 200 comprises a jacking cylinder 210 and a limiting plate 220, the jacking cylinder 210 is fixedly installed on the limiting plate 220, the limiting plate 220 is fixedly installed on the rack 100, and the support plate 320 is fixedly connected to the piston rod of the jacking cylinder 210.
[0028] Optionally, the limiting plate 220 is located below the support plate 320, and the jacking cylinder 210 is located below the limiting plate 220. The jacking cylinder 210 is vertically arranged, the piston rod of the jacking cylinder 210 penetrates through the limiting plate 220 and is connected to the support plate 320 above the limiting plate 220. When the piston rod of the jacking cylinder 210 extends or retracts, the support plate 320 can be driven to move up and down, and when the support plate 320 moves, the sliding plate 310 slides along the guide rail 120.
[0029] As Figure 1 and Figure 3 shown, the support plate 320 is provided with a buffer 321 and a limiting adjustment screw 322, when the buffer 321 contacts the limiting plate 220, the jacking cylinder 210 operates at a reduced speed, and when the limiting adjustment screw 322 contacts the limiting plate 220, the jacking cylinder 210 stops operating.

According to the arrival height of the suction cup 420, the depth of the limiting adjustment screw 322 extending into the support plate 320 can be adjusted. When the product in the carrier reaches the preset position, the jacking cylinder 210 drives the support plate 320 to descend, first, the support plate 320 will contact the buffer 321, at this time, the jacking cylinder 210 slows down to descend, until the support plate 320 contacts the hard limiting adjustment screw 322, the jacking cylinder 210 stops running, at this time the spring in the buffer 321 is compressed. The use of the buffer 321 and the limiting adjustment screw 322 can further improve the stability of the jacking cylinder 210 operation, and improve the positioning accuracy of the support plate 320.
[0031] The operation process of the present application comprises the following steps:
[0032] Step 1: When the carrier loaded with products reaches the position of the turnover unloading, the vacuum generator 110 starts to work to provide negative pressure for the suction cup 420, and the suction nozzle 421 generates suction force;
[0033] Step 2: The jacking cylinder 210 is changed from the initial extended state to the retracted state, driving the support frame 300 and the rotating unit 400 to descend, through the buffering and limiting action of the buffer 321 and the limiting adjustment screw 322, the suction nozzle 421 is lowered to a height that can just fit the product;
[0034] Step 3: The suction nozzle 421 uses the suction force to adsorb the product, and the lifting cylinder 210 is extended again to make the product separate from the carrier and reach the unloading height;
[0035] Step 4: After the hollow rotating platform 410 drives the product to turn over 180°, the product reaches the unloading position, the vacuum generator 110 stops running, and the suction nozzle 421 releases the product, thereby automatically realizing the transfer of the product from the carrier to the unloading position.
