[0002] With the continuous advancement of realizing the full-process unmanned process in the room, more and more experimental operations can be replaced by intelligent equipment, for example, the laboratory cap opening and closing action. In the past, experimental personnel manually operated the operation process, which was tedious, time-consuming and laborious, and had a certain risk. For large-torque threaded experimental devices such as reaction kettles, it is difficult to open manually, and there is currently no suitable intelligent operation device. For small-torque cap opening operations such as opening and closing the cap of a new crown virus test tube, some cap opening devices are provided in the prior art, such as:
[0003] Patent application No. 2021101657006, patent name: new crown virus sampling tube intelligent cap opening robot, the invention realizes the intelligent opening of new crown virus test tubes through the setting of the drive and control integrated cap opening device, the robot and the two-finger gripper. However, this type of mechanism cannot realize intelligent operation of large-torque threaded workpieces. If larger grippers and robots with greater load are required to achieve greater torque operation, the entire cap opening robot device will be too large, the structure will not be compact, installation will be inconvenient, and the cost will be high.
[0004] Patent application No. 2020107438883, patent name: test tube cap opening machine and cap opening method using the test tube cap opening machine, the invention arranges the push mechanism horizontally and the working channel with a test tube rack on one side, sets the sample inlet mechanism on the front side of the push mechanism, and installs the sample outlet mechanism on the rear side of the push mechanism. The clamping end of the test tube clamping mechanism and the clamping end of the test tube cap clamping mechanism are located directly above the middle position of the working channel. The test tube is clamped by the test tube clamping mechanism and moved upward, the test tube cap is clamped by the test tube cap clamping mechanism, the test tube cap and the test tube are separated, and the separated test tube is clamped by the test tube clamping mechanism and returned to the initial position. The device can effectively reduce human involvement in the process. During the cap opening process, the test tube only needs to be clamped once, and the complex alternate clamping operation is saved.

DETAILED DESCRIPTION
[0030] The application is further described below in conjunction with the accompanying drawings.
[0031] As Figures 1-5 shown, a full-automatic laboratory large-torque intelligent cap screwing instrument for micro-reaction kettle intelligent cap opening mainly includes a clamping jaw 1 for fixing a reaction kettle body 21, a large-torque rotary clamp 3 for opening and closing a reaction kettle cover 22, a force control sliding table 4 for driving the vertical movement of the large-torque rotary clamp 3, a touch screen 5 for automatically or manually controlling the clamping jaw 1, the large-torque rotary clamp 3 and the force control sliding table 4, and a fixed base 6.
[0032] The clamping claw 1 is fixedly mounted on the fixed plate 61 via the first fixed base 12. The upper part of the first fixed base 12 is fixedly mounted with a first clamping seat 13. The first clamping seat 13 is internally matched with a first slider 14 and a first umbrella-shaped push rod 16. The bottom of the first fixed base 12 is fixedly connected to a first clamping motor 11. The bottom of the first clamping motor 11 is connected to a first drive controller 111 via signal and mechanical connection. The first drive controller 111 can control the rotation of the rotor inside the first clamping motor 11, so that the first umbrella-shaped push rod 16 moves up and down along the axis of the first clamping motor 11, thereby driving the first slider 14 to move left and right radially along the first clamping seat 13, thereby driving the first finger 15 fixed on the first slider 14 to move radially towards or away from the first clamping seat 13, thereby realizing the clamping and loosening of the reactor body 21.
[0033] The high-torque rotating gripper 3 is vertically positioned directly above component 1, and the axis of the rotating head 34, the axis of the first clamping seat 13, and the axis of the reactor 2 are collinear. High torque generally refers to the torque required to open a bottle cap without external assistance. For example, an adult hand can twist a bottle cap with a maximum torque of approximately 5 Nm. With external assistance, such as setting the bottle cap to a specific geometric shape like a wrench, theoretically, infinite force could be applied. This is clearly impractical for automated laboratory operations, and existing cap openers or machines, even by increasing their size, cannot fundamentally solve this problem. The high-torque rotating gripper of this invention has a torque exceeding 30 Nm, approximately six times that of a human hand. The clamping force of this invention generally refers to a force exceeding what a human hand can maintain for an extended period. An adult hand's clamping force is approximately 100 N, while this invention achieves a clamping force of approximately 900 N, ensuring the reactor is firmly secured.
[0034] The high-torque rotary gripper 3 includes a rotary motor 31, an integrated base 32, a bottom cover 33, a rotating head 34, a second gripping motor 35, a second slider 36, and a second finger;
[0035] The rotary motor 31 is equipped with a second drive controller 313, and the second clamping motor 35 is equipped with a third drive controller 352; the rotary motor 31 and the second clamping motor 35 are arranged side by side on the first plane 324 and the second plane 325 of the base on the top of the integrated base 32; the integrated base 32 and the bottom cover 33 are fixedly connected by screws, the rotating head 34 is located below the bottom cover 33, and the rotating head 34 is equipped with a second slider 36, which is provided with a second finger;
[0036] A grooved pull rod 351 is screwed onto the output shaft of the second clamping motor 35. A screw bearing 345 is fitted inside the grooved pull rod 351. A second umbrella-shaped push rod 341 is connected to the screw bearing 345. The second umbrella-shaped push rod 341 cooperates with the second slider 36. A second gear 343 is fitted onto the second umbrella-shaped push rod 341. A third gear 344 is provided on the output shaft 311 of the rotary motor 31. A first gear 312 meshes between the third gear 344 and the second gear 343.
[0037] The integrated base 32 has a first through hole 321, and the groove-shaped tie rod 351 is slidably fitted in the first through hole 321 of the integrated base 32. The integrated base 32 has a first groove 322 located below the first through hole 321, and a second groove 323 located parallel to the first groove 322. The first groove 322 and the second groove 323 are respectively used for mounting the third gear 344 and the second gear 343, and the first groove 322 and the second groove 323 are connected.
[0038] The bottom cover 33 is provided with a bottom cover through hole 332, and the bottom cover through hole 332 is provided with a bottom cover groove 331 (forming a limiting step, the upper structure of the first groove 322 of the base is the same); the second gear 343 is fixed in the first groove 322 of the base of the integrated base 32 and the bottom cover groove 331 of the bottom cover 33 through the first bearing 342 arranged symmetrically above and below.
[0039] The high-torque rotating gripper 3 is fixedly connected to the linear slider 43 via the second connecting plate 45 and the first connecting plate 44. The linear slider 43, the first connecting plate 44, the second connecting plate 45 and the high-torque rotating gripper 3 can move up and down along the axis of the reactor 2 under the control of the slide table motor 41 by the fourth drive controller 46.
[0040] Working process, principles, and design ideas:
[0041] The third drive controller 352 controls the rotation of the rotor inside the output motor of the second clamping motor 35, and drives the T-shaped screw on the upper part of the grooved pull rod 351, which is threaded with the rotor inside the second clamping motor 35, to move up and down. This causes the grooved pull rod 351 to move up and down within the first through hole 321 of the base. When the grooved pull rod 351 moves upward, it drives the screw bearing 345, which is engaged with the grooved pull rod 351, to move up and down. When the screw bearing 345 moves upward, it drives the second umbrella-shaped push rod 341 to move upward. The upward movement of the second umbrella-shaped push rod 341 drives the second slider 36 to move inward along the radial direction of the rotating head 34. Three sliders are evenly distributed in the circumferential direction.
[0042] Since the force is mutual, the screw bearing 345 is driven by the groove type pull rod 351 to move upward, and the second gear 343 has a downward movement tendency. Therefore, the second gear 343 is fixed in the base first groove 322 of the integrated base 32 and the bottom cover groove 331 of the bottom cover 33 through the first bearing 342 symmetrically arranged above and below, the integrated base 32 and the bottom cover 33 are fixed and connected by screws, the bottom cover 33 is fixed and connected with the first connecting plate 44 through the second connecting plate 45, the first connecting plate 44 is fixed and connected with the linear slide 43 through screws, and the linear slide 43 can move up and down along the linear slide 42 under the drive of the slide motor 41. The linear slide 42 is fixed and connected with the fixed plate 61 through the mounting plate 47. If the slide motor 41 does not move, the linear slide 43, the first connecting plate 44, the second connecting plate 45, the integrated base 32 and the bottom cover 33 will be relatively stationary. At this time, the second gear 343 cannot move downward, so the second slide block 36 will move left and right along the radial direction of the rotating head 34 under the drive of the second umbrella-shaped push rod 341 and the screw bearing 345 fixedly connected with the second umbrella-shaped push rod 341. If the groove type pull rod 351 moves downward, the second slide block 36 moves outward. At this time, the second slide block 36 can completely drive the second finger 37 to realize the clamping and loosening of the reactor cover body 22.
[0043] In order to realize the rotary motion of the rotating head 34, the second slide block 36 and the second finger 37, the groove type pull rod 351 is matched and slidably connected through the base first through hole 321 arranged on the integrated base 32, and can only realize upward and downward movement and cannot realize relative rotary motion. If rotary motion is required, the second gear 343 is driven to rotate the rotating head 34 and the auxiliary connecting piece, and the third gear 344 and the first gear 312 are arranged beside the second gear 343. The first gear 312 can drive the third gear 344 to rotate under the control of the second drive controller 313 driving the rotary motor 31, so that the second gear 343 is driven to rotate, thereby realizing the rotation of the rotating head 34 with the second slide block 36 and the second finger 37. In order to solve the mechanical interference problem of the upward and downward linear motion of the groove type pull rod 351 and the rotation of the second gear 343, the screw bearing 345 can be used to solve the mechanical transmission interference problem, thereby realizing the transmission of large clamping force and large torque. Under the drive of the force control slide table 4, the large torque rotary clamp jaw 3 rotates upward or downward with the reactor cover body 22, and the reactor body 21 is clamped and fixed by the clamping electric jaw 1, which does not move relative to the fixed base 6. Therefore, the opening and closing of the reactor cover are realized.
[0044] The above are only specific embodiments of the present application. Obviously, the present application is not limited to the above embodiments, and there are many variations, such as switch bottle cap diameter greater than 100mm large torque thread type reagent bottle cap, rotating M20 or more thread type parts, switch oil drum thread bottle cap, etc., all variations that can be directly derived or inferred from the disclosed content by those skilled in the art should be considered within the protection scope of the present application.

The third gear (344) drives the second gear (343) to rotate, thereby realizing the rotation of the rotating head (34) with the second slider (36) and the second finger (37) rotating. 4) The fourth drive controller (46) controls the slide motor (41) to drive the linear slide to run, so that the high torque rotating gripper (3) carries the reactor cover (22) to rotate up or down, while the reactor body (21) is clamped and fixed by the clamping electric gripper (1) and does not move relative to the fixed base (6). Then, the force control slide automatically compensates for the Z-direction lifting and lowering movement of the reactor cover caused by the rotation of the threaded cover during the opening and closing process.
