the worktable is also fixedly provided with a servo motor, an output shaft of the servo motor is fixedly connected to the rotating shaft, and the mechanical arm can swing back and forth between a first position and a second position under the driving of the servo motor; when the mechanical arm is positioned at the first position, the swing rod extends along the horizontal direction, and a suction port of the sucking disc faces upwards; when the mechanical arm is at the second position, the swing rod extends along the horizontal direction, and the suction port of the sucker faces downwards.

Before this backplate turning device's robotic arm work, at first make the gripper rotate to the primary importance on, make the suction inlet of sucking disc up, then utilize the transfer device, the backplate that will accomplish one side deburring process shifts to the gripper from a deburring device on, utilize the vacuum chuck on the gripper, adsorb the backplate on the gripper, start servo motor and make robotic arm rotate the second place, make the suction inlet of sucking disc down, eliminate the negative pressure of sucking disc, make the backplate drop to corresponding brace table on, accomplish the turn-over action, then make the backplate get into next process, carry out deburring processing to the locating hole from the opposite side. And starting the servo motor again to return the mechanical arm to the first position, and turning the back plate for the next time. Utilize this application can overturn the backplate smoothly, carry out the deburring processing to the locating hole from the both sides of backplate, guarantee the deburring effect, avoid producing adverse effect.

Furthermore, in order to keep the action synchronous, the two mechanical claws are symmetrically arranged relative to the swing rod.

Specifically, each gripper comprises a central rod, the central rod is parallel to the swing rod, two support rods are respectively arranged on two opposite sides of the central rod, and each support rod is provided with a sucker. A plurality of sucking discs can be installed to this design, makes the backplate can remain stable on the gripper, avoids dropping at manipulator arm upset process.

Furthermore, the cross beam comprises a support frame fixedly installed on the swing rod and a positioning rod detachably installed on the support frame, two opposite ends of the positioning rod are respectively detachably provided with a connecting head, and each connecting head is provided with one mechanical claw. This design can be changed the gripper as required to adapt to the backplate of unidimensional not.

Detailed Description

Referring to fig. 1, a backboard overturning device comprises a worktable 10 and a mechanical arm rotatably mounted on the worktable, wherein the mechanical arm comprises a rotating shaft 21 rotatably mounted on the worktable and a swing rod 22 fixedly connected to the rotating shaft. Two bearing blocks 11 are installed on the table at intervals, and the rotating shaft 21 is rotatably installed on the two bearing blocks through bearings. The robot arm in fig. 1 is in an upright position.

A cross beam is fixedly mounted at one end of the swing rod 22 far away from the rotating shaft, the cross beam comprises a support frame 23 fixedly mounted on the swing rod 22 and a positioning rod 24 mounted on the support frame 23, two opposite ends of the positioning rod are respectively detachably mounted with a connector 25, and each connector 25 is mounted with a mechanical claw 30. Wherein the positioning rod is connected to the support frame via a first bolt 26. The supporting frame is parallel to the positioning rod and is perpendicular to the swing rod, namely the cross beam is perpendicular to the swing rod. The swing rod is connected to the middle part of the cross beam, and the two mechanical claws are symmetrically arranged relative to the swing rod.

In this embodiment, each gripper 30 includes a central rod 31, the central rod 31 is parallel to the swing rod 22, two support rods 32 are respectively disposed on two opposite sides of the central rod 31, a suction cup 33 is disposed on each support rod 32, a vacuum tube 35 is connected to the suction cup, the suction cup is made of silica gel, and the suction cup is used for adsorbing the back plate. The vacuum line 35 is connected to a vacuum system, on which a release valve 36 is mounted, which in this embodiment is a three-way valve.

A servo motor 13 is also fixedly mounted on the worktable 10, and an output shaft of the servo motor 13 is fixedly connected to the rotating shaft 21. Referring to fig. 2 and 3, the robot arm can swing back and forth between a first position and a second position under the driving of the servo motor, fig. 2 is a state diagram of the robot arm in the first position, and fig. 3 is a state diagram of the robot arm in the second position. When the mechanical arm is positioned at the first position, the swing rod extends along the horizontal direction, and a suction port of the sucking disc faces upwards; when the mechanical arm is at the second position, the swing rod extends along the horizontal direction, and the suction port of the sucker faces downwards.

Before this backplate upset robotic arm work, at first make the gripper rotate to the primary importance on, make the suction inlet of sucking disc up, then utilize the transfer device, the backplate that will accomplish one side deburring process shifts to the gripper from a deburring device on, revolve wrong three-way valve, make the sucking disc produce the negative pressure, make the backplate adsorb on the sucking disc, restart servo motor, make robotic arm rotate the second place, then revolve wrong three-way valve once more, eliminate the negative pressure of sucking disc, make the backplate drop on a supporting bench 40, then make the backplate get into next process, carry out deburring processing to the locating hole from the opposite side. And starting the servo motor again to return the mechanical arm to the first position, and turning the back plate for the next time.
