The groove 602 has a first position-limiting portion 602a, a second position-limiting portion 602b, a third position-limiting portion 602c, and a fourth position-limiting portion 602 d; the hook 603 is configured to slide in the groove 602 in a single direction, and when the hook 603 slides to the first limiting portion 602a, the clamping jaw 503 is in an open-close state; when the hook 603 slides to the second position-limiting portion 602b, the third position-limiting portion 602c, and the fourth position-limiting portion 602d, the clamping jaw 503 is in a clamping state.
A first sliding groove section 606 is arranged between the first limiting part 602a and the second limiting part 602b in the groove 602, and the first sliding groove section tends to ascend from the first limiting part 602a to the second limiting part 602b (the reason for the ascending tendency is that steps are formed between the sliding groove sections behind the first limiting part 602a and the second limiting part 602 b); a second sliding groove section 607 is arranged between the second limiting part 602b and the third limiting part 602c in the groove 602, and a first step 606a is formed corresponding to the first sliding groove section 606; a third sliding groove section is arranged between the third limiting part 602c and the fourth limiting part 602d in the groove 602, and a second step 607a is formed corresponding to the second sliding groove section 607; between the fourth position-limiting portion 602d and the first position-limiting portion 602a in the groove 602 is a fourth chute section 609, which is inclined upward from the fourth position-limiting portion 602d to the first position-limiting portion 602a (the reason for the inclined upward is to eliminate the height difference with the first chute section 606) and is finally engaged with the first chute section 606, and the fourth chute section 609 is formed with a third step 608a with respect to the third chute section 608.

Wherein, the connecting base 502 is further provided with an elastic sheet 505 for abutting against the hook 603. The elastic sheet 505 is used for abutting against the hook 603 to enable the hook 603 to move tightly against the surface of the groove 602, if there is no elastic sheet 505, the hook 603 may loosen during movement to enable the hook not to slightly abut against the surface of the groove 602 but not to be separated from the groove 602, and at this time, the step height of the first step 606a, the second step 607a or the third step 608a may not be enough to block the hook 603, so that the hook 603 may reversely return and cannot reach the limiting portion, and the clamping jaw 503 cannot grasp the test tube cap.
Wherein, the bottom plate 1 is provided with a position sensor 102, and the push plate 3 is provided with a photosensitive sheet 301 matched with the position sensor 102. When the position sensor 102 senses the photosensitive web 301, the driving mechanism 2 stops operating.
The working process of the test tube uncapping mechanism is as follows:
(I) uncapping Process
The main machine 201 of the driving mechanism 2 controls the driving rod 202 to move downwards, so as to drive the push plate 3 to move downwards, and as the nut 402 in the screw rod 4 is fixed on the fixing plate 101, the push plate 3 drives the screw rod 401 in the screw rod 4 to move downwards, so that the screw rod 401 is self-rotated, and the clamping jaw module 5 connected with the screw rod 401 is also driven to rotate;
along with the downward movement of the jaw module 5, the test tube cap on the test tube originally located below the jaw module 5 abuts against the top plate, so that the buckle assembly 6 moves upward relative to the driving rod 202 or the screw 401, the hook 603 is originally located at the first limit portion 602a, and at this time, the hook starts to move toward the second limit portion 602b along the path S1, because the first rotating shaft 504 is connected with the sleeve 501, the hook 503 connected with the buckle main seat 601 through the second rotating shaft 604 does not move relatively, and the first rotating shaft 504 moves upward relative to the sliding groove 503a through the shape of the sliding groove 503a in the hook 503, so that the hook 503 is tightened inward, and the elastic sheets 505 on the hook 503 are adjusted according to the diameter of the test tube cap and clamp the test tube cap, and finally clamp the test tube cap;
at this time, when the hook 603 reaches the second limiting portion 602b at the lowest point, the positioning column 701 is pressed to contract upwards, when the positioning column 701 contracts to the highest point, the pressure sensor in the pressure expansion device 7 senses the pressure, the host 201 of the driving mechanism 2 controls the driving rod 202 to move upwards, and the clamping jaw module 5 rotates while moving upwards, so that the test tube cap can be conveniently taken off; because the driving rod 202 moves upwards, the pressure on the positioning column 701 is reduced, the positioning column 701 extends downwards to restore the original shape, the test tube cap slides downwards along with the positioning column 701, and the clamping hook 503c on the clamping jaw 503 hooks the lower edge of the test tube cap, so that the test tube cap is prevented from completely sliding; due to the obstruction of the first step 606a, the hook 603 can only move along the path S2 to the third position-limiting portion 602c, but cannot return along the path S1; although there is a certain height difference between the second position-limiting portion 602b and the third position-limiting portion 602c, since the sliding slot of the clamping jaw 503 has a vertical section 503a ', the angle of the clamping jaw 503 will not be substantially changed when the first rotating shaft 504 moves in the vertical section 503 a' of the sliding slot, and therefore, when the hook 603 moves to the third position-limiting portion 602c, the clamping jaw 503 still grasps the test tube cap. The test tube with the cap removed is sent to the next operation of sampling, detecting and the like.
(II) Cap installation Process
When the test tube is returned, the test tube cap held by the holding jaws 503 needs to be loaded back into the test tube. The main body 201 of the driving mechanism 2 controls the driving rod 202 to move downwards, after the test tube cap is inserted into the test tube, the buckle assembly 6 moves upwards relative to the driving rod 202 or the screw 401, and due to the blocking of the second step 607a, the hook 603 can only move towards the fourth limiting portion 602d along the path S3, and at this time, the clamping jaw 503 still grabs the test tube cap and is not released; when the hook 603 moves to the fourth position-limiting portion 602d, the clamping jaw module 5 has completely screwed the test tube cap, and the positioning column 701 is pressed to contract upward until the positioning column 701 contracts to a vertex, the pressure sensor in the pressure expansion device 7 senses the pressure, the host 201 of the driving mechanism 2 controls the driving rod 202 to move upward, due to the blocking of the third step 608a, the hook 603 can only move to the first position-limiting portion 602a along the path S4, and the clamping jaw 503 opens outward by moving downward in the sliding chute relatively through the first rotating shaft 504, and finally the test tube cap is completely released.
As the driving rod 202 moves upward, when the position sensor 102 senses the photosensitive web 301, the driving mechanism 2 stops operating, and thus a complete uncapping and capping process is completed. The next test tube can then be uncapped and capped by a manipulator or a rack carousel to start the next cycle. The number of apparatuses and the scale of the process described herein are intended to simplify the description of the present invention. Applications, modifications and variations of the present invention will be apparent to those skilled in the art.
While embodiments of the utility model have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the utility model pertains, and further modifications may readily be made by those skilled in the art, it being understood that the utility model is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
