The implementation principle of the posture changing device for the components is as follows: after the workpiece comes out from the previous process, the workpiece is placed at the central position of the turntable 3, then the air pump makes the inside of the circulation channel 72 in a negative pressure state, at this time, the workpiece is adsorbed on the upper surface of the turntable 3, then the driving motor 2 is started to rotate the turntable 3 by a predetermined angle, in the process, the abutting block 51 moves from the far rest position 6 to the correcting position 522 to enable the four pushing blocks 4 to abut against the workpiece at the same time to correct the posture of the workpiece, then the abutting block 51 moves from the correcting position 522 to the next far rest position 6, finally the driving motor 2 is turned off to stop the rotation of the turntable 3, at this time, the distance between one end of the pushing block 4 close to the workpiece and the workpiece is farthest, so that the workpiece is taken down from the turntable 3.
The method for changing the posture of the component comprises the following steps:
s1: placing a workpiece at the position of the center of a circle on the upper surface of the turntable 3;
s2: starting the driving motor 2 to rotate the turntable 3;
s3: when the turntable 3 rotates, the push block 4 moves close to the workpiece and abuts against the workpiece to correct the posture of the workpiece;
s4: the push block 4 moves away from the workpiece;
s5: when the push block 4 is at the farthest distance from the workpiece, the driving motor 2 is turned off, and the rotary table 3 stops rotating;
s6: the workpiece is removed from the turntable 3 and sent to the next process.
Referring to fig. 2 and 4, in the present embodiment, when the rotation angle is a multiple of 45 °, the abutment block 51 can be moved from the far rest position 6 to the other far rest position 6, and as in embodiment 1, after the previous workpiece is adjusted in posture, the rotary table 3 does not need to be rotated in the reverse direction for reset adjustment, and the next workpiece can be directly placed on the rotary table 3, so that the posture changing operation for the next workpiece can be directly started.
In addition, in this embodiment, the workpiece is similarly triangular prism, pentagonal prism or hexagonal prism, and only the included angle between the adjacent distal rest position 6 and the correction position 522 needs to be adjusted correspondingly.
Referring to fig. 2 and 5, if the workpiece is triangular prism-shaped, three pushing blocks 4 are provided, the included angle between adjacent pushing blocks 4 is 120 °, the rotation angle of the rotating disc 3 is 90 °, and for convenience of description, when the rotating disc 3 is not moved, the projections of the positions where the three abutting blocks 51 abut against the guide plate 52 on the horizontal plane are A, B and C, so as to represent the relative position relationship between the three abutting blocks 51, and when the rotating disc 3 is rotated, the distal rest positions 6 on the guide plate 52, which are matched with the three abutting blocks 51, are a1, B1 and C1, the correction positions 522 are a2, B2 and C2, and then the trajectories of the three abutting blocks 51 abutting against the guide plate 52 are plotted, it is found that the projections of the trajectories of the three abutting blocks 51 on the horizontal plane are not overlapped, so that the trajectories of the three abutting blocks 51 abutting against the guide plate 52 are respectively located on the horizontal planes at different heights, and the guide plate 52 can now be seen to be formed of one main guide 524 and three compensating guides 525 on each layer.
Referring to fig. 2 and 5, in this embodiment, after the rotary table 3 rotates 90 °, the three abutting blocks 51 can be moved from the far rest position 6 to the next far rest position 6 adjacent to each other, so that the resetting operation is not needed after the previous workpiece is changed in posture, although the structure of the guide plate 52 is more complicated, the posture changing device can be changed in different postures only by changing different structures, and the adaptability of the posture changing device is improved greatly.
Embodiment 4, referring to fig. 2 and 6, is different from embodiment 1 in that when the included angle between adjacent pushing blocks 4 is not consistent with the rotation angle of the rotating disc 3 and is not a multiple of the rotation angle, and when the rotation angle of the rotating disc 3 is not a multiple of 360 °, the guiding plates 52 need to be arranged in accordance with the number of the abutting blocks 51, as will be described below.
Referring to fig. 2 and 6, if the workpiece is triangular prism-shaped, three pushing blocks 4 are provided, the included angle between adjacent pushing blocks 4 is 120 °, the rotation angle of the turntable 3 is 50 °, three guide plates 52 are provided, the three guide plates 52 are respectively abutted to the three abutting blocks 51, specifically, the projection of the guide plates 52 on the horizontal plane is arc-shaped, wherein the guide plates 52 are provided with a start position 521, a correction position 522 and an end position 523 which are sequentially distributed along the circumferential direction, when the abutting blocks 51 are located at the start position 521, the workpiece can be placed on the turntable 3, when the abutting blocks 51 are located at the correction position 522, the posture of the workpiece is corrected, and when the abutting blocks 51 are located at the end position 523, the workpiece is taken off from the turntable 3.
Referring to fig. 2 and 6, in order to facilitate description of the movement trajectories of the three abutting blocks 51, when the turntable 3 is not in motion, the projections of the positions where the three abutting blocks 51 abut against the three guide plates 52 on the horizontal plane are set to be A, B and C, so as to represent the relative positional relationship between the three, the start positions 521 where the three guide plates 52 abut against the three abutting blocks 51 are set to be a1, B1 and C1, the correction positions 522 are set to be a2, B2 and C2, the end positions 523 are set to be A3, B3 and C3, and then the trajectories where the three abutting blocks 51 abut against the three guide plates 52 are depicted, respectively, it is found that the trajectory of each abutting block 51 cannot form a closed ring shape, so that the three guide plates 52 cannot form a closed tube shape, and only can be matched with the respective abutting blocks 51 in a tile shape alone.
Referring to fig. 2 and 6, in the present embodiment, after the abutting block 51 moves to the ending position 523, the turntable 3 needs to be rotated reversely to reset the abutting block 51 to the starting position 521, so as to prepare for changing the posture of the next workpiece.
In summary, in the four embodiments provided, in actual use, when the postures to be converted are different, only the corresponding guide plate 52 needs to be replaced, and the parameters of the motor are adjusted, so that the adaptability of the posture changing device can be greatly improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
