The pole feeding module 4 is used to provide the pole 2 to be assembled,

The two-axis suction sealing ring feeding module 7 is used to cover the sealing ring 1 provided by the suction sealing ring feeding module 6 on the pole 2 on the carrying pole jig 81 .

The basic working principle of the present invention is to put the semi-finished pole 2 in the tray on the bearing pole jig 81 through the manipulator to take the pole module 5, cooperate with the rotating position of the turntable module 8, and then suck the seal ring through the two axes. The material module 7 absorbs the sealing ring 1 provided by the sealing ring feeding module 6 and sets it on the pole 2, and finally picks and places the pole module 5 by the robot to grab the finished product and put it into the material tray. During the process, due to the application of the pole-carrying fixture 81, the problem that the gap between the pole 2 in the material tray is too large and the grasping is unstable is solved ingeniously.

Please refer to FIG. 5 , the sealing ring feeding module 6 includes a vibrating plate 61 , a direct vibration channel 62 , a fourth top cylinder 63 , a conical head 64 , a blocking block 65 , the feed end of the direct vibration channel 62 and the vibration The disc 61 is connected, the discharge end of the feeding rail 62 extends to the blocking block 65, and the blocking block 65 is above the fourth top cylinder 63. When the sealing ring reaches the blocking block through the direct vibration channel, then the fourth top cylinder The top of 63 pushes the sealing ring to the conical head 64, which is convenient for the two axes to suck the vacuum suction nozzle 75 of the sealing ring feeding module 7 for suction.

In this embodiment, there are two vacuum suction nozzles 75, and a dual-axis suction seal ring feeding module 7 is adopted. Since the bearing pole fixture on the turntable has two stations, in order to reduce the equipment CT, a dual-axis is adopted. The suction sealing ring feeding module 7 is used to assemble the suction sealing ring. Therefore, the direct vibration current 62 has two channels. When the sealing ring reaches the groove of the blocking block 43, the optical fiber senses that there is material, and the upper cylinder 63 is lifted, so that the sealing ring is placed on the conical head 64, and then the cylinder 73 of the sealing ring feeding module 7 is drawn horizontally by the two axes. , so that the vacuum suction nozzle 75 reaches the top of the sealing ring. At this time, the vacuum suction nozzle 75 of the cylinder 72 is stretched up and down to suck the material of the sealing ring, and so on.

Referring to FIG. 8 , the two-axis suction sealing ring feeding module 7 includes a first sliding block 71 , an upper and lower telescopic cylinder 72 , a horizontal telescopic cylinder 73 , a second sliding block 74 and a vacuum suction nozzle 75 . The vacuum suction nozzle 75 is connected with the upper and lower telescopic cylinder 72 through the second sliding block 74 , and the operation of sucking the sleeve sealing ring 1 is completed after being connected with the horizontal telescopic cylinder 73 .

Please refer to FIGS. 3 to 4 , the pole feeding module 4 includes a motor 41 , a first material distribution plate 42 , a first top cylinder 43 , a second top cylinder 48 , a clamping cylinder 44 , a blocking cylinder 45 , and a blocking cylinder 45 . Block 46 , third top cylinder 47 , second material distribution tray 49 . The clamping cylinder 43 is lifted up to manually place the material tray on the first material distribution tray position 42, and then the clamping cylinder 42 is released and the first cylinder is lowered so that the material tray falls on the synchronous belt. As the motor 41 rotates forward, the material tray moves forward along with the synchronous belt to the position of the material tray, and then the third top-up cylinder 47 lifts the material tray to the stopper 46 to fix the material tray. Then the manipulator picks and places the clamping jaws 523 of the pole module 5 to grab the pole 2 and place it on the carrying jig. After completion, the manipulator takes the finished product back to the tray. Then the motor 41 is reversed, the material tray is blocked by the backflow and the cylinder is raised so that the material tray stops at the second material distribution plate position, and then the second upper cylinder lifts the material tray for manual unloading. so cycle.

Referring to FIG. 6 to FIG. 7 , the robot pick-and-place module 5 includes a robot arm 51 and a pick-and-place module 52 . The picking and unloading module 52 includes a clamping jaw cylinder 521 , an up and down telescopic cylinder 522 , a clamping jaw 523 and a stopper 524 . The picking and unloading module is divided into two parts: the charging of the pole and the unloading of the pole, both of which are two stations.

When the present invention is used, the material tray is manually placed on the first material distribution tray position 42, and then the clamping cylinder 42 releases the first cylinder and descends so that the material tray falls on the synchronous belt. As the motor 41 rotates forward, the material tray moves forward along with the synchronous belt to the position of the material tray, and then the third top-up cylinder 47 lifts the material tray to the stopper 46 to fix the material tray. Then the manipulator picks and places the clamping jaws 523 of the pole module 5 to grab the pole 2 and place it on the carrying jig. After completion, the manipulator takes the finished product back to the tray. Then the motor 41 is reversed, the material tray is blocked by the backflow and the cylinder is raised so that the material tray stops at the second material distribution plate position, and then the second upper cylinder lifts the material tray for manual unloading. The semi-finished pole 2 in the tray is placed on the bearing pole jig 81 by the manipulator taking the pole module 5, and the rotating position of the turntable module 8 is matched, and then the sealing ring is sucked by the two-axis suction sealing ring feeding module 7. The sealing ring 1 provided by the feeding module 6 is set on the pole 2. When the sealing ring reaches the blocking block through the direct vibration flow channel, then the fourth top cylinder 63 tops the sealing ring to the conical head 64, The vacuum suction nozzle 75 of the sealing ring feeding module 7 has been easily sucked by the two axes. When the sealing ring reaches the groove of the blocking block 43, the optical fiber senses that there is material, and the upper cylinder 63 is lifted, so that the sealing ring is placed on the conical head 64, and then the cylinder 73 of the sealing ring feeding module 7 is drawn horizontally by the two axes. , so that the vacuum suction nozzle 75 reaches the top of the sealing ring. At this time, the vacuum suction nozzle 75 of the cylinder 72 is stretched up and down to suck the sealing ring for feeding, and the turntable rotating manipulator picks up the finished product and unloads it in the material tray.

The main technical points in the process: the carrying fixture module 81 : the manipulator grabs the pole 2 onto the carrying block 812 , and then the pneumatic finger 813 clamps the pole 2 . It should be noted that the shape of the bottom of the pole 2 is inconsistent, and there is a 30-degree gap on one side, so there is a possibility that the center of the pole will deviate when clamping, but the shape of the front of the correction block 811 avoids this problem, the front of the correction block 811 The shape of the arc is made to meet the sharp corner and will not directly withstand it.
