Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-Figure 3The cam 2 is a kind of track 2 that is fixed on the workbench 1, and the track 2 is provided with a pair of track 3 that are symmetrical to each other, and a pair of track 4 is provided on the inner side of the track 2. The track 2 is provided with a pair of track 3 that are symmetrical to each other, and a pair of track 4 is provided on the inner side of the track 2. The track 2 is provided with a pair of track 3 that are symmetrical to each other, and an adjusting screw rod 5 is rotatably installed on the front side of the track 2 through a bearing seat. The adjusting screw rod 5 is parallel to the track 2, and two screw nuts are arranged on the adjusting screw rod 5, and the two screw nuts are respectively fixed to the two track clamping arms 3. The left and right halves of the adjusting screw rod 5 have opposite rotation directions, and the two screw nuts on the adjusting screw rod 5 are respectively matched with the two screw threads on the adjusting screw rod 5. By controlling the rotation of the adjusting screw rod 5, the two screw nuts on the screw rod can drive the two track clamping arms 3 to move simultaneously to the middle or to both sides along the track 2, thereby completing the action of clamping or releasing the track.
[0018] A synchronous pulley is installed at one end of the adjusting screw rod 5, a servo motor 7 is installed on the top of the clamp fixing plate 1, a motor pulley 8 is installed on the output shaft of the servo motor 7, and the motor pulley 8 is connected to the synchronous pulley 6 through a synchronous belt transmission. The servo motor 7 can drive the motor pulley 8 to rotate, and then the adjusting screw rod 5 can be driven to rotate through the transmission of the synchronous belt. The forward and reverse rotation of the output shaft of the servo motor 7 can be controlled.
[0019] See also Figure 2 A cylinder 9 is installed on the front of the clamping jaw fixing plate 1, and the cylinder 9 is located in the central position of the front of the clamping jaw fixing plate 1. The output rod of the cylinder 9 faces directly in front of the clamping jaw fixing plate 1, and a pressure plate 10 is installed at the end of the output rod. The cylinder 9 is located between the two wire clamping arms 3, and the distance between the cylinder 9 and the two wire clamping arms 3 is equal. No matter whether the two wire clamping arms 3 are close to each other or far away from each other, the pressure plate 10 is always located in the middle of the two clamping jaws 4. In the process of clamping the wire coil, the pressure plate 10 is controlled by the cylinder 9 to press on the outer edge of the wire coil, which can play a role in pressing the wire and adjusting the coaxiality of the wire coil and the clamping jaw 4, so that the clamping jaw 4 can grip more firmly.
[0020] The working principle and use process of the utility model are as follows: when the wire coil gripper mechanism used on the mechanical arm is used, when the wire coil after coating is transported to the temporary storage platform, the mechanical arm 11 is started to work, and the wire coil gripper mechanism is moved to the grabbing point on the temporary storage platform, and then the servo motor 7 is started, and the screw rod 5 is adjusted to rotate forward through the synchronous belt drive, so that the two wire clamping arms 3 on the clamping claw fixing plate 1 move toward each other along the slide rail 2, and the two clamping claws 4 approach each other and start to clamp the wire coil. During this period, the cylinder 9 is started to control the pressing plate 10 to press the outer edge of the wire coil, so that the clamping claws 4 can grasp more firmly. After the wire coil is clamped, the mechanical The arm 11 lifts the wire coil to leave the temporary storage platform and moves the wire coil to the storage point. At this time, if the axis of the wire coil is not perpendicular to the ground, the joints of the robot arm 11 rotate until the axis of the wire coil is perpendicular to the ground. After the axis is perpendicular to the ground, the robot arm 11 places the wire coil steadily on the storage point, and then the servo motor 7 starts to drive the adjusting screw 5 to reverse, so that the two jaws 4 move away from each other and return to their original positions. The jaws 4 release the wire coil, and at the same time the cylinder 9 starts to control the pressure plate 10 to return to its original position. After the wire coil is completely released, the robot arm 11 lifts the wire coil gripper back to its original position, and an operation process of the gripper mechanism is completed.
