As shown in fig. 1 to 5, an embodiment of the present application provides a cup 11 clamping and centering mechanism 53, where the cup 11 clamping and centering mechanism 53 includes: a positioning platform 52, a centering mechanism 53 and a clamping mechanism 51; wherein the content of the first and second substances,

the clamping mechanism 51 is arranged above the positioning platform 52 and used for clamping the upper end of the cup body 11;

the centering mechanism 53 comprises a centering block 532 and a lifting and rotating unit 531, the lifting and rotating unit 531 is arranged at the lower end of the positioning platform 52, and the output end of the lifting and rotating unit 531 penetrates through the positioning platform 52 and is connected with the centering block 532 for driving the centering block 532 to lift and rotate;

the outer contour of centering block 532 matches the inner contour of the open end of cup 11, and centering block 532 may extend into the open end of cup 11 and abut against the inner wall of cup 11 such that the axis of cup 11 coincides with the axis of centering block 532.

In this embodiment, this cup centre gripping centering mechanism is installed on the carousel main part that can rotate around self axis, is provided with a plurality of baffles 10 on the carousel main part 1, and a plurality of baffles 10 have certain interval along the circumference evenly distributed of carousel main part 1 between the adjacent baffle 10, and cup positioner 5 then is located between the adjacent baffle 10. In this embodiment, the cup positioning device 5 comprises a positioning platform 52, a centering mechanism 53 and a clamping mechanism 51, wherein the positioning platform 52 is located between the two partition plates 10 and is installed on the turntable main body 1, and the clamping mechanism 51 is installed on the turntable main body 1 and is located above the positioning platform 52, so as to clamp the upper end of the fixed cup 11. Since the cup 11 needs to rotate during laser cutting and flame explosion, the clamping mechanism 51 in this embodiment also has a degree of freedom to rotate around its axis after clamping and fixing the cup 11.

While cup 11 may be inclined at an angle when fixture 51 holds fixed cup 11, it is desirable that the axis of cup 11 be perpendicular to the horizontal since cup 11 subsequently needs to be rotated to effect laser cutting and flame popping. To this end, the cup positioning device 5 in the present embodiment further includes a centering mechanism 53, and the centering mechanism 53 here functions to straighten the inclined cup 11 even if its axis is perpendicular to the horizontal plane. Specifically, the centering mechanism 53 is composed of a centering block 532 and a lifting and rotating unit 531, wherein a fixed part of the lifting and rotating unit 531 is installed below the positioning platform 52, and an output end of the lifting and rotating unit is connected with the centering block 532 after extending out of the positioning platform 52. The centering block 532 can be driven to ascend, descend and rotate by the lifting and rotating unit 531.

When the upper end of the cup 11 is clamped by the clamping mechanism 51, the open end of the cup 11 faces downward, i.e., toward the centering block 532. To center the cup 11, the elevation rotation unit 531 is controlled to lift the centering block 532. The outer contour of centering block 532 matches the inner contour of the open end of cup 11, and centering block 532 may extend into the open end of cup 11 and abut against the inner wall of cup 11 such that the axis of cup 11 coincides with the axis of centering block 532. The axis of the centering block 532 is always perpendicular to the horizontal plane, so that the axis of the cup body 11 is perpendicular to the horizontal plane through the centering block 532.

In order to improve the processing efficiency, in this embodiment, one positioning platform 52 corresponds to two clamping mechanisms 51 and two centering mechanisms 53, the two clamping mechanisms 51 and the two centering mechanisms 53 respectively correspond to each other up and down and are distributed along the circumferential direction of the turntable main body 1, and both the two clamping mechanisms 51 and the centering mechanisms 53 can independently act.

To avoid damage to cup 11 during extension of centering block 532 into cup 11, centering block 532 is made of an elastic material in this embodiment. For cups and lifters, centering block 532 may be integrally configured as a truncated cone-shaped structure that allows it to straighten cup 11 while gradually extending into the open end of cup 11.

Of course, it is understood that the centering block 532 may be a separate block-like structure or may be a pawl-like structure that is expandable outwardly. When the latter is employed, centering block 532 extends into cup 11 in a collapsed configuration and is then caused to expand outwardly and press against the inner wall of cup 11 by the drive mechanism.

In this embodiment, after the centering block 532 extends into the cup 11, the outer surface of the centering block 532 is attached to the inner surface of the cup 11, and the rotation of the centering block 532 can drive the cup 11 to rotate. Therefore, the lifting and rotating unit 531 in this embodiment has the function of driving the centering block 532 to lift and rotate at the same time.

Of course, it is understood that the rotation function of the cup 11 can also be realized by the clamping mechanism 51, that is, a motor capable of driving the clamping mechanism 51 to rotate is added to the clamping mechanism 51.

As shown in fig. 2 and 4, for the cup and the tappet, the upper end surface is a flat surface after being placed upside down, so that the clamping mechanism 51 can stably clamp and fix the cup body 11 of the type, in this embodiment, the clamping mechanism 51 comprises a vacuum adsorption device 512 and an elastic clamping device 511; the vacuum suction means 512 is for sucking the upper end of the cup 11, and the elastic holding means 511 is for holding the ring side of the fixed cup 11.

As shown in fig. 3 and 4, the vacuum adsorption device 512 includes a vacuum tube 512a and an adsorption nozzle 512b disposed at a lower end of the vacuum tube 512a, and the vacuum tube 512a is connected to a vacuum generation device;

the elastic clamping device 511 comprises a clamping sleeve 511a sleeved on the vacuum tube 512a, the lower end of the clamping sleeve 511a is hinged with three clamping jaws 511b, and the clamping jaws 511b are distributed along the circumferential direction of the clamping sleeve 511 a; at least one jaw 511b may be driven to rotate about a hinge point to grip the ring side of cup 11, and jaw 511b may be driven to rotate about the hinge point by a drive motor, or may be converted from linear motion to rotational motion by a cylinder and gearing mechanism.

For better clamping of cup 11, the lower end of jaw 511b is provided with an elastic clamping portion 511c for abutting against the surface of cup 11.

Since there is a problem that part of cup 11 is not processed satisfactorily and needs to be screened out during the processing, the positioning platform 52 is further modified to solve the above problem, as shown in fig. 2.

In this embodiment, the positioning platform 52 includes a positioning plate 521 and a deflection driving mechanism 522, the deflection driving mechanism 522 is disposed on the side surface of the turntable main body 1, and the positioning plate 521 is disposed at the output end of the deflection driving mechanism 522, so that the positioning plate 521 can rotate around the horizontal axis;

the elevation rotation unit 531 is provided at a lower end of the positioning plate 521.

Specifically, it should be noted that the cup body 11 and the material cap should be separated after the cup body is subjected to laser cutting and flame-frying. If the cup body and the nut are separated normally at the moment, the cup body is clamped and fixed by the clamping mechanism 51, the nut is positioned on the centering block 532, and at the moment, the turntable main body 1 continues to rotate to drive the cup body 11 to enter a screening station, so that the nut which is successfully separated from the centering block 532 is removed. And centering block 532 and lift rotation unit 531 all install on locating plate 521, consequently accessible deflection actuating mechanism 522 drives the rotation of locating plate 521 and makes the whole slope of locating plate 521, and centering block 532 also inclines to certain angle in step this moment for the nut that is located centering block 532 drops to recovery position. The cup body is held and fixed by the holding mechanism 51, and is not affected by the operation of the swing driving mechanism 522.

If the cup body and the material cap are not separated normally at this time, the cup body 11 which is not separated from the cup body and the material cap needs to be screened out. At this time, the clamping mechanism 51 needs to cancel clamping of the cup body 11, and the deflection driving mechanism 522 is controlled to drive the positioning plate 521 to rotate and tilt, so that the cup body 11 which is located on the centering block 532 and does not meet the requirement can fall to the recovery position.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
