Please refer to fig. 1 to 5. The embodiment of the utility model provides a rotary lifting sensing mechanism which comprises a first driving piece 1, a mounting block 2, a sensing piece 3 and a material taking part 4.

Wherein the first drive member 1 has an output shaft (not shown) extending in a vertical direction. The output shaft is located below the fixed end of the first driving member 1. The mounting block 2 is fixedly connected to the output shaft in the vertical direction. The output shaft is rotatable about a rotation axis extending in the vertical direction with respect to the mounting block 2. The output shaft runs through in installation piece 2, the stiff end of installation piece 2 and first driving piece 1 is fixed relatively. The sensing piece 3 is fixedly connected to the mounting block 2.

The material taking part 4 is connected with the output shaft. The top end of the material taking part 4 is fixedly connected with an induction coil 41, and the rotation axis is parallel to the central axis of the induction coil 41 and is positioned in the induction coil 41. The induction coil 41 has a first position facing the induction element 3 and a second position below the induction element 3. When the induction coil 41 is located at the first position, the induction piece 3 can sense the induction coil 41; when the induction coil 41 is located at the second position, the induction element 3 cannot sense the induction coil 41. The bottom end of the material taking part 4 is fixedly provided with a suction nozzle 42 for taking materials. The output shaft can drive the material taking part 4 to rotate by taking the rotation axis as a center. The material taking part 4 can slide along the vertical direction relative to the output shaft so as to drive the induction coil 41 to switch between the first position and the second position.

The rotary lifting sensing mechanism provided by the embodiment is provided with the first driving piece 1, and the material taking part 4 can be driven by the output shaft to rotate by taking the rotation axis as the center, so that the suction nozzle 42 can rotate by any angle, and the problem of inconsistent material feeding angles is solved. The material taking part 4 can slide along the vertical direction relative to the output shaft, so that the suction nozzle 42 can be lifted and lowered according to the requirement, and the material to be taken is prevented from being crushed.

In addition, by arranging the induction coil 41 and the induction piece 3, when the material to be taken is placed with the front face upwards, the induction coil 41 is positioned at the second position, as shown in fig. 1, the induction piece 3 cannot sense the induction coil 41, and the material taking can be performed normally; when the material to be taken is placed with the back face upwards, the material taking part 4 is propped against the back face of the material to slide upwards, so that the induction coil 41 is located at the first position, as shown in fig. 2, the induction piece 3 can sense the induction coil 41, and thus the material taking operation is canceled, and therefore the mechanism can identify whether the material to be taken is the abnormal material with the back face or not. The rotary lifting sensing mechanism is simple in structure, low in manufacturing cost, convenient to maintain and high in compatibility.

In the present embodiment, as shown in fig. 1, the rotation-lift-sensing mechanism further includes a mounting plate 5. The mounting plate 5 extends in a vertical direction. The fixed end of the first driving piece 1 and the mounting block 2 are fixedly connected to the same side of the mounting plate 5, and the mounting block 2 is located below the fixed end of the first driving piece 1. A second driving member (not shown) may be connected to the other side of the mounting plate 5, and the second driving member may drive the mounting plate 5 to move in a vertical direction. Specifically, the moving end of the second driving member is fixedly connected to the mounting plate 5. The second driving member may be a cylinder, a linear motor, or the like.

As shown in fig. 3, the sensing element 3 is disposed on a side of the mounting block 2 away from the mounting plate 5, and the sensing surface 31 of the sensing element 3 is located below the mounting block 2, so that the sensing element 3 and the sensing coil 41 are not blocked by the mounting block 2.

Preferably, the first driving member 1 is a servo motor, and is configured to drive the material taking portion 4 to rotate about the rotation axis. The output shaft of the first driving member 1 is the moving end thereof, and a mounting seat 6 can be further arranged between the fixed end of the first driving member 1 and the mounting plate 5. The mounting seat 6 is used for bearing the fixed end of the first driving piece 1. The mounting 6 may be L-shaped. Part of the L-shaped mounting seat 6 extends along the horizontal direction and is fixedly connected to the fixed end of the first driving piece 1, and the other part of the L-shaped mounting seat 6 extends along the vertical direction and is fixedly connected to the mounting plate 5.

As shown in fig. 3 and fig. 4, the bottom end of the output shaft is fixedly provided with a sliding rail 7 extending along the vertical direction, the material taking part 4 is fixedly connected with a sliding block 8, the sliding block 8 is matched with the sliding rail 7, and the sliding block 8 can drive the material taking part 4 to move up and down along the sliding rail 7. In another embodiment, the slide rail 7 may be fixed to the material taking portion 4, and the slider 8 is fixed to the output shaft. The slide rail 7 and the slider 8 may be configured to define a synchronous rotation of the take-out portion 4 and the output shaft of the first driving member 1, while allowing the take-out portion 4 to have a degree of freedom of vertical movement.

As shown in fig. 4, a limiting block 9 is disposed on a surface of the bottom of the sliding rail 7 facing the material taking portion 4, and is used for limiting the lowest position of the sliding block 8. When the bottom surface of the sliding block 8 is attached to the upper surface of the limiting block 9, the sliding block 8 is at the lowest position, and the induction coil 41 is at the second position.

As shown in fig. 4, a limiting surface 10 is disposed on a surface of the top of the sliding rail 7 facing the material taking portion 4, and is used for limiting the highest position of the sliding block 8. When the top surface of the sliding block 8 is attached to the limiting surface 10, the sliding block 8 is at the highest position, and the induction coil 41 is at the first position.

In this embodiment, an elastic member 11 for buffering stress in the vertical direction is disposed between the limiting surface 10 and the material taking portion 4. The elastic member 11 may be a spring extending in a vertical direction. As shown in fig. 5, the material taking section 4 is provided with a receiving chamber 43 extending in the vertical direction for receiving the elastic member 11 between the induction coil 41 and the suction nozzle 42.

Preferably, the central axis of the induction coil 41 coincides with the rotation axis. The induction coil 41 is circular, and can judge the front and back of the material when the material taking part 4 rotates to any angle.

The embodiment of the utility model uses one sensing piece 3 and one sensing coil 41, and effectively identifies whether materials (front and back surfaces) are abnormal or not according to whether the sensing piece 3 has sensing signals or not, and the elastic piece 11 is arranged for buffering, so that the phenomenon that the material taking part 4 collides with the mounting block 2 is prevented.

In a specific application scenario, the front surface of the material has grooves for the suction nozzles 42 to suck, and the back surface of the material has no grooves, so that the suction surface of the front surface of the material (i.e. the bottom of the grooves) is lower than the suction surface of the back surface of the material. Firstly, the angle of the suction nozzle 42 of the material taking part 4 is adjusted by using the first driving member 1 according to the angle of the material, when the suction nozzle 42 descends to the position for taking the material, if the material faces upward, as shown in fig. 1, the sensing member 3 is located at the second position, the sensing member 3 cannot sense the sensing member 41 (at this time, the sensing member 3 can send a normal signal), and the material taking can be performed normally. If the back surface of the material faces upward, the suction surface of the back surface of the material is higher than the suction surface of the front surface of the material, so that the suction nozzle 42 can be propped against the suction surface of the back surface of the material in the descending process, the material taking part 4 moves upward along the sliding rail 7, the elastic piece 11 is stressed and buffered, as shown in fig. 2, the induction coil 41 moves upward to a first position, the induction piece 3 can sense the induction coil 41 (at this time, the induction piece 3 can send an abnormal signal), the material is automatically judged to be abnormal, and the material taking operation is canceled.
