Detailed Description

Referring to fig. 1 to 5, a cam carrying mechanism includes two columns 1, a beam 2 connected to the columns 1, and a mounting plate 3 fixed to the beam 2, wherein a driving device is mounted on the mounting plate 3, the driving device is connected to a transmission shaft 20, the driving device includes a servo motor 4, the servo motor 4 is connected to a speed reducer 5, the speed reducer 5 is connected to the transmission shaft 20, the transmission shaft 20 is connected to a swing arm 19, the swing arm 19 is provided with a kidney-shaped hole 191, a cam bearing 18 is disposed in the kidney-shaped hole 191, the mounting plate 3 is further provided with a cam track plate 6, the cam track plate 6 is provided with a cam track groove 61, the cam bearing 18 is disposed in the cam track groove 61, and the cam track groove 61 is an inverted U-shaped.

The swing arm 19 is further provided with an induction block 192, the cross beam 2 is provided with two extreme position sensor mounting plates 7, the two extreme position sensor mounting plates 7 are both provided with extreme position sensors 8, and the extreme position sensors 8 are positioned on two sides of the cam track plate 6. When the swing arm 19 swings left and right to the extreme positions, the sensing block 192 just triggers the two extreme position sensors 8. The limit position sensor 8 is electrically connected with the servo motor 61, and the servo motor 61 can control the motion state of the swing arm according to the signal sent by the limit position sensor 8.

The crossbeam 2 is connected with the linear slide rail 9 that sets up along the X axle direction, is equipped with two sliders 10 on the linear slide rail 9, and two sliders 10 are connected with sliding plate 11, and sliding plate 11 is equipped with a plurality of linear bearing 12 that set up along the Z axle direction, is equipped with the guide pillar 13 that can follow the motion of Z axle direction in the linear bearing 12, and the top of guide pillar 13 is connected with drive plate 14, and the bottom of guide pillar 13 is connected with suction nozzle mounting panel 15, is equipped with a plurality of suction nozzles on the suction nozzle mounting panel 15.

The driving plate 14 is connected with a cam bearing 18, the top of the sliding plate 11 is provided with a limit block 17, the limit block 17 is used for limiting the Z-axis direction movement of the driving plate 14, and when the swing arm swings left and right to a limit position, the bottom of the driving plate 14 just contacts with the limit block 17.

The working principle of the invention is as follows:

when the swing arm is at the right end limit position, the suction nozzle sucks a product, the limit position sensor at the right side senses a signal of the induction block and sends an instruction to the servo motor, a transmission shaft of the servo motor rotates to drive the swing arm to rotate, the swing arm drives the cam bearing to move in the cam track groove, meanwhile, the cam bearing drives the driving plate to move, the driving plate drives the suction nozzle to ascend along the Z-axis direction through the guide pillar, after the cam bearing passes the vertex of the cam track groove, the suction nozzle descends along the Z-axis direction, meanwhile, the guide pillar drives the sliding plate to move to the left end along the X-axis direction, when the swing arm is at the left end limit position, the limit position sensor at the left side senses a signal of the induction block and sends an instruction to the servo motor, the servo motor stops moving, the suction nozzle puts down the product, and then the movement of the product from one work station to the next work station is realized, the servo motor continues to move back and forth to move the product from one station to the next until the product is finished at each station.
