[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To achieve the torsion separation function, this application provides a torsion separation device, comprising:

[0028] The system comprises a drive motor 1, a transmission mechanism 2, and a gripper mechanism 3. One end of the transmission mechanism 2 is connected to the drive motor 1, and the other end is connected to the gripper mechanism 3. The gripper mechanism 3 is used to clamp an item and rotate it to achieve torsion and separation. The transmission mechanism 2 includes a first gear set 5, a second gear set 8, and a third gear set 13. The first gear set 5 includes a first incomplete gear 501, which is connected to the output shaft of the drive motor 1. The first incomplete gear 501 drives the second gear set 8 and the third gear set 13. The second gear set 8 includes at least a second incomplete gear 801 and a third incomplete gear 805, which drive the opening and closing of the gripper. The third gear set 13 drives the gripper mechanism 3 to rotate.

[0029] The transmission mechanism 2 decomposes the driving force of the drive motor 1 and transmits it to the gripper mechanism 3 step by step, so as to realize the gripping, rotating and releasing operations of the gripper mechanism 3. The transmission mechanism 2 includes a first gear set 5, a second gear set 8, and a third gear set 13. The drive motor 1 transmits power to the first gear set 5. The first gear set 5 is equipped with a first incomplete gear 501. The first incomplete gear 501 divides the driving force into two parts. One part of the power is transmitted to the third gear set 13 to realize the rotation of the gripper mechanism 3. Specifically, the tooth circumference angle of the first incomplete gear 501 can be set by those skilled in the art according to actual needs. In one embodiment of this application, the tooth circumference angle of the first incomplete gear 501 is 120°. The other part of the power of the first incomplete gear 501 is transmitted to the second gear set 8. The second gear set 8 is equipped with a second incomplete gear 801 and a third incomplete gear coaxially arranged. Taking advantage of the fact that the third incomplete gear cannot be reversed, the second incomplete gear 801 divides the power transmitted from the first incomplete gear 501 into two parts. The two parts of the power drive the third incomplete gear respectively. The rotation of the third incomplete gear in different directions realizes the gripping and releasing action of the gripper. The working steps of the twisting and separating device provided in this application are as follows: the gripper first clamps, then rotates to achieve twisting and breaking, and after twisting and breaking, the gripper separates to complete the release action.

[0030] In one embodiment, the first gear set 5 includes a first incomplete gear 501, a first gear 502, and a second gear 503. During the rotation of the first incomplete gear 501, each rotation of the first incomplete gear 501 causes the sector teeth to sequentially mesh with the first gear 502 and the second gear 503, thereby intermittently driving the first gear 502 and the second gear 503 to rotate. The first gear 502 drives the second gear set 8 via a first rotating shaft 6. Specifically, the first gear 502 and the second incomplete gear 801 are coaxially connected via the first rotating shaft 6. The second gear 503 drives the third gear set 13 via a second rotating shaft 7. Specifically, the second gear 503 and the eighth gear 1301 in the third gear set 13 are coaxially connected via the second rotating shaft 7.

[0031] The third gear set 13 includes at least an eighth gear 1301 and a ninth gear 1302. The second gear 503 drives the eighth gear 1301 through the second rotating shaft 7. The eighth gear 1301 meshes with the ninth gear 1302. The base of the gripper mechanism 3 is mounted on the gear shaft of the ninth gear 1302, so that the rotation of the ninth gear 1302 drives the gripper mechanism 3 to rotate.

[0032] In one embodiment, the second gear set 8 includes a second incomplete gear 801, a third gear 802, a fourth gear 803, and a third incomplete gear 805. The third incomplete gear 805 is coaxially connected to the input gear 303. The second incomplete gear 801 drives the third gear 802 and the fourth gear 803. Specifically, the tooth circumference angle of the second incomplete gear 801 can be set by those skilled in the art according to actual needs. In one embodiment of this application, the tooth circumference angle of the second incomplete gear 801 is set to 120°. Each rotation of the second incomplete gear 801 causes the sector teeth to sequentially mesh with the third gear 802 and the fourth gear 803, thereby intermittently driving the third gear 802 and the fourth gear 803 to rotate. The third gear 802 and the fourth gear 803 respectively drive the third incomplete gear 805. The number of transmission gears between the third gear 802 and the fourth gear 803 and their respective third incomplete gears 805 differs by 1, configured to make the rotation directions of the third incomplete gears different. This drives the opening and closing of the grippers. It can be understood that when the third incomplete gear rotates forward, it causes the grippers to move closer together, clamping the item to be broken. When the third incomplete gear rotates backward, it causes the grippers to move away from each other, thus releasing the broken item. Specifically, in one embodiment, the third gear 802 coaxially drives the sixth gear 806, the sixth gear 806 meshes with the seventh gear 807, the seventh gear 807 meshes with the third incomplete gear 805, and the fourth gear 803 coaxially drives the fifth gear 804, the fifth gear 804 meshes with the third incomplete gear 805.

[0033] In one embodiment, the gripper mechanism 3 is provided with an input gear 303, which is coaxially connected to two third incomplete gears via a third rotating shaft 12. The gripper mechanism 3 also includes a first rack chuck 302 and a second rack chuck 305. The rack of the first rack chuck 302 meshes with the input gear 303, and the rack of the second rack chuck 305 meshes with the input gear 303. The configuration is such that when the input gear 303 rotates in a first direction, the chucks of the first rack chuck 302 and the second rack chuck 305 move closer to each other; when the input gear 303 rotates in a second direction, the chucks of the first rack chuck 302 and the second rack chuck 305 move further apart. The first direction and the second direction are opposite. Specifically, the first direction refers to the input gear 303 rotating in the forward direction, and the second direction refers to the input gear 303 rotating in the reverse direction. The Sohu gripper mechanism 3 also includes a pressure plate 304, which is used to fix the first rack chuck 302 and the second rack chuck 305.

[0034] In one embodiment, the third rotating shaft 12 is housed inside the gear shaft of the ninth gear 1302 via a bearing sleeve, and the third rotating shaft 12 drives the input gear 303 through the gripper base 301. When the gear shaft of the ninth gear 1302 rotates, the third rotating shaft 12 does not rotate. Specifically, the third rotating shaft 12 can be housed inside the gear shaft of the ninth gear 1302 via a ball spline bushing.

[0035] In one embodiment, the torsion separation device further includes a first mounting plate 4, a second mounting plate 9, a third mounting plate 10, and a fourth mounting plate 11. The first gear set 5 is mounted between the first mounting plate 4 and the second mounting plate 9. The second gear set 8 is mounted between the second mounting plate 9 and the third mounting plate 10. The third gear set 13 is mounted between the third mounting plate 10 and the fourth mounting plate 11. The gripper mechanism 3 is mounted on the fourth mounting plate 11.

[0036] In one embodiment, the workflow of this application is as follows: The output shaft of the drive motor 1 is connected to the first incomplete gear 501, driving the first incomplete gear 501 to rotate. The first incomplete gear 501 first meshes with the first gear 502, the first gear 502 drives the second incomplete gear 801, the second incomplete gear 801 first drives the fourth gear 803, the fourth gear 803 drives the fifth gear 804, the fifth gear 804 drives the third incomplete gear 805, and the third incomplete gear 805 drives the input gear 303 in a forward transmission. The forward rotation causes the first rack chuck 302 and the second rack chuck 305 to move closer together, completing the clamping operation. Simultaneously, as the gripper mechanism 3 completes the clamping operation, the first incomplete gear 501 engages with the first gear 502 and continues to rotate, meshing with the second gear 503. The second gear 503 is driven to rotate, thus transmitting power to the eighth gear 1301 of the third gear set 13. The eighth gear 1301 meshes with the ninth gear 1302, completing the clamping operation. The ninth gear 1302 then rotates, driving the gripper mechanism 3 to rotate and complete the torsion operation. Simultaneously, the second incomplete gear 801 engages with the fourth gear 803 and continues to rotate, meshing with the third gear 802. The third gear 802 drives the third incomplete gear 805, which in turn drives the input gear 303 to reverse. After the torsion is completed, the third incomplete gear 805 drives the input gear 303 to reverse, so that the first rack chuck 302 and the second rack chuck 305 move away from each other, thereby completing the release of the torsioned object.
