DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1As shown, a reaction cup transport mechanism with a mixing function includes a base 1, and the upper end of the base 1 is connected to a horizontally sliding transport seat 3 for transporting the reaction cup to the detection position. The transport seat 3 is connected to a horizontally sliding second drive frame 6, and the second drive frame 6 is perpendicular to the movement trajectory of the transport seat 3. The side wall of the second drive frame 6 is connected to a first drive frame 4 that slides up and down, and the first drive frame 4 is connected to a cup grabbing mechanism 5. The position of the grabbing mechanism is adjusted by the first drive frame 4 and the second drive frame 6 to achieve accurate grabbing and placement of the reaction cup. The entire structure is controlled by a PLC controller 2 arranged at one end of the base 1.

[0028] like Figure 8-9 As shown, the cup grabbing mechanism 5 includes a clamping seat 504 connected to the first driving frame 4, and the bottom of the clamping seat 504 is connected to two clamping claws 505 for grabbing the reaction cup through a rotating shaft 508. A limit block 509 is provided between the two clamping claws 505. The two clamping claws 505 are connected by a tension spring 506. The minimum opening size of the two clamping claws 505 is limited by the limit block 509. When grabbing, the clamping claw 505 moves toward the reaction cup, and the reaction cup pushes the two clamping claws 505 open. The clamping claw 505 is sleeved on the outside of the reaction cup, and the clamping claw 505 clamps the reaction cup under the action of the tension spring 506. The first driving frame 4 moves upward, and the clamping claw 505 takes the reaction cup out of the cup rack. The upper end of the clamping seat 504 is connected to a vibration motor 507, and the solution in the reaction cup is vibrated and mixed by the vibration motor 507.

[0029] The specific vibration mixing structure is:

[0030] like Figure 7As shown, the side wall of the first driving frame 4 is connected with a bracket 605 and a horizontal lifting rod 401, and the clamp seat 504 is connected to the lifting rod 401 through a rubber shock absorbing plug 503. The rubber shock absorbing plug 503 is a cylindrical structure and is made of rubber and has a certain elasticity. The bracket 605 is connected with a vertical upper positioning rod 606 and a lower positioning rod 607. The upper end of the clamp seat 504 is connected with a shockproof rod 502. The shockproof rod 502 is provided with a positioning hole 501 that cooperates with the upper positioning rod 606 or the lower positioning rod 607. When the lifting rod 401 drives the clamp seat 504 to move upward, the shockproof rod 502 cooperates with the upper positioning rod 606. When the lifting rod 401 drives the clamp seat 504 to move downward, the shockproof rod 502 cooperates with the lower positioning rod 607. The distance between the upper positioning rod 606 and the lower positioning rod 607 is greater than the thickness of the shockproof rod 502. When placing the reaction cup, the shockproof rod 502 is sleeved on the outer side of the upper positioning rod 606 or the lower positioning rod 607 to ensure the stability of the clamping claw 505 and ensure that the reaction cup can be accurately grasped or placed; when the transport vibration occurs, the shockproof rod 502 is located between the upper positioning rod 606 and the lower positioning rod 607. Since the shockproof rod 502 loses the restraint of the upper positioning rod 606 or the lower positioning rod 607, the clamp seat 504 is only connected by the rubber shock-absorbing plug 503. Therefore, under the action of the vibration motor 507, the clamp seat 504 will swing, thereby fully mixing the solution in the reaction cup.

[0031] In addition, a reflection sensor 608 (pm2-1 f10 sensor) is provided on the bracket 605. The reflection sensor 608 is located on one side of the clamp seat 504 and can be used to detect errors in the reaction cup to ensure the accuracy of grasping.

[0032] The clamping seat 504 can move in the X, Y, and Z directions under the action of the transfer seat 3, the first drive frame 4, and the second drive frame 6, so as to realize the transfer and accurate grasping of the reaction cup. Its three-axis moving structure adopts the method of synchronous belt pulling and guide rail guidance, and the specific structure is as follows:

[0033] like Figure 2-4 As shown, a horizontal first guide rail 102 and a first synchronous belt 103 are provided on the base 1, the first synchronous belt 103 is driven by a first motor 104, a first photoelectric sensor 101 is provided on one side of the first guide rail 102, and a first slider 302 cooperating with the first guide rail 102, a first pulling plate 301 connected to the first synchronous belt 103, and a first detection plate 303 cooperating with the first photoelectric sensor 101 are provided at the lower end of the transfer seat 3.

[0034] like Figure 6 As shown, a horizontal second guide rail 304 and a second synchronous belt 305 are provided on the transfer seat 3. The second synchronous belt 305 is driven by a second motor 307. A second photoelectric sensor 306 is provided on one side of the second guide rail 304. Figure 5As shown, the lower end of the second driving frame 6 is provided with a second pulling plate 601 connected to the second synchronous belt 305 , a second detection plate 610 matched with the second photoelectric sensor 306 , and a second sliding block 602 matched with the second guide rail 304 .

[0035] A vertical third synchronous belt 603 and a third guide rail 609 are provided on the side wall of the second driving frame 6. The third synchronous belt 603 is driven by a third motor 611. A third photoelectric sensor 604 is provided on one side of the third guide rail 609. A third pull plate 402 connected to the third synchronous belt 603 and a third slider 403 cooperating with the third guide rail 609 are connected to the side wall of the first driving frame 4. The upper end of the second driving frame 6 cooperates with the third photoelectric sensor 604.

[0036] The origin or the starting position of the mechanism can be located by photoelectric sensors to ensure the accuracy of the mechanism's operation.

[0037] At the beginning, the mechanism is located at the origin, that is, the position of the photoelectric sensor. When the reflection sensor 608 detects the presence of the reaction cup, the mechanism starts, and the reaction cup is grasped by the clamp 505 for transportation. During the transportation process, the reaction cup is shaken and evenly performed by the vibration motor 507, so that the transportation and vibration of the reaction cup are carried out simultaneously, saving time and improving efficiency.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
