On the other hand, the accommodating cavity 422e can provide a space for avoiding installation of the connecting assembly 420, so that the connecting assembly 420 can eliminate interference of other components and can be effectively connected with the sliding block 421.

In some embodiments, the mounting assembly 430 includes a movable plate 431, a pressing plate 432 and a guide 433, the movable plate 431 and the pressing plate 432 are both of a substantially rectangular parallelepiped structure with a large length, and the movable plate 431 may be fixed on the third side wall 422d of the connecting assembly 420 by bolts. The pressing plate 432 is located directly below the movable plate 431, that is, both the movable plate 431 and the pressing plate 432 are spaced apart in the vertical direction such that a certain gap exists between the movable plate 431 and the pressing plate 432. The upper ends of the pressing rods 440 are fixed on the movable plate 431, for example, ten pressing rods 440 can be fixed on the movable plate 431, the pressing rods 440 are uniformly arranged at intervals on the same straight line along the horizontal direction, and the distance between two adjacent pressing rods 440 is equal to the distance between two through holes 210 on the supporting plate 200. When the pressing rods 440 are located at suitable positions above the supporting plate 200, the orthographic projections of all the pressing rods 440 on the supporting plate 200 respectively fall into different through holes 210, so that the pressing rods 440 can form a one-to-one correspondence with the through holes 210, and when the movable plate 431 drives the pressing rods 440 to move downward, ten pressing rods 440 can be inserted into one row of through holes 210 on the supporting plate 200, and exactly ten through holes 210 are formed in one row. When ten pressing rods 440 are simultaneously inserted into ten through holes 210, ten caps 20 can be simultaneously covered on ten test tubes. The pressing plate 432 is provided with a through hole 432a, and the lower end of the pressing rod 440 is inserted into the through hole 432a, so as to realize the sliding fit of the pressing rod 440 and the through hole 432 a. In operation, the pressing plate 432 is pressed against the supporting plate 200.

In some embodiments, the guide 433 includes a guide rod 433a and a spring 433b, the movable plate 431 is provided with a sliding hole 431a, a lower end of the guide rod 433a can be fixed on an end portion of the pressing plate 432, the spring 433b is pressed between the movable plate 431 and the pressing plate 432, meanwhile, the spring 433b can be a cylindrical spring, the spring 433b is sleeved outside the guide rod 433a, an upper end of the spring 433b is pressed against the movable plate 431, and a lower end of the spring 433b is pressed against the pressing plate 432. The movable plate 431 is provided with a sliding hole 431a, and the guide rod 433a is inserted into the sliding hole 431a, so that the sliding fit relation between the guide rod 433a and the sliding hole 431a is realized. In the working process, the guide rod 433a is fixedly connected with the pressing plate 432 so that the relative position of the guide rod 433a and the pressing plate 432 is kept unchanged, the pressing rod 440 is fixedly connected with the movable plate 431 so that the relative position of the pressing plate 432 and the pressing rod 440 is kept unchanged, under the condition that the pressing plate 432 is in contact with the loading plate 200, when the movable plate 431 moves downwards to be close to the pressing plate 432, the spring 433b is compressed to store energy, the gap between the movable plate 431 and the pressing plate 432 is reduced, the pressing rod 440 slides downwards relative to the through hole 432a in the pressing plate 432, and meanwhile, the guide rod 433a moves upwards relative to the sliding hole 431a in the. On the contrary, when the pressing plate 432 is stopped to contact the supporting plate 200, the spring 433b releases energy to extend, the pressing plate 432 moves downward relative to the movable plate 431 under the pushing force of the spring 433b, and the guide rod 433a moves downward relative to the sliding hole 431a of the movable plate 431.

In some embodiments, the guide rod 433a is a substantially cylindrical rod, the guide rod 433a includes a limiting portion 433c and a guiding portion 433d, the limiting portion 433c is connected to an upper end of the guiding portion 433d, and a cross-sectional dimension of the guiding portion 433d may be slightly smaller than a cross-sectional dimension of the sliding hole 431a, so that the guiding portion 433d maintains a clearance fit relationship with the sliding hole 431a, and the guiding portion 433d can slide smoothly relative to the sliding hole 431 a. Meanwhile, the cross-sectional size of the stopper portion 433c is larger than that of the slide hole 431a, so that the stopper portion 433c cannot enter the slide hole 431 a. In fact, the stopper portion 433c functions as a good stopper to maintain the maximum distance between the movable plate 431 and the pressing plate 432. When the spring 433b releases energy to push the pressing plate 432 to move downward relative to the movable plate 431, the distance between the movable plate 431 and the pressing plate 432 is gradually increased, and meanwhile, the guide portion 433d of the guide rod 433a moves downward relative to the sliding hole 431a on the movable plate 431, so that the guide portion 433d drives the limiting portion 433c to move downward relative to the sliding hole 431a, when the limiting portion 433c abuts against the movable plate 431 and cannot pass through the sliding hole 431a, the pressing plate 432 stops moving downward relative to the movable plate 431 due to the interference effect of the limiting portion 433c, and at this time, the distance between the movable plate 431 and the pressing plate 432 is maximum and cannot be increased continuously.

The number of the guide rods 433a may be four, two guide rods 433a are fixed to one end of the pressing plate 432, and two guide rods 433a are also fixed to the other end of the pressing plate 432. At this time, the number of the springs 433b is four, and one spring 433b is sleeved on each guide rod 433 a. By providing the four guide rods 433a, stability and accuracy of the relative movement between the pressing plate 432 and the movable plate 431 can be ensured. Of course, the number of the guide rods 433a and the springs 433b may also be increased as appropriate, and when the number of the springs 433b is increased, the restoring force of the movement of the pressing plate 432 with respect to the movable plate 431 may be increased.

In fact, when the pressing plate 432 is in contact with the loading plate 200, the pressing plate 432 stops moving in the vertical direction, and at this time, the movable plate 431 may move downward relative to the stationary pressing plate 432 through the sliding fit relationship of the pressing rod 440 and the through hole 432a, and the sliding fit relationship of the guide rod 433a and the sliding hole 431a, thereby reducing the interval between the movable plate 431 and the pressing plate 432. Meanwhile, when the pressing rod 440 ascends a short distance along with the movable plate 431, the pressing plate 432 presses against the cap plate 21 under the elastic force of the spring 433b, so as to prevent the cap plate 21 from being separated from the supporting plate 200 along with the ascending of the pressing rod 440. When the ascending distance of the movable plate 431 is continuously increased to drive the pressing plate 432 to leave the cap plate 21, the pressing plate 432 moves downward relative to the movable plate 431 under the elastic force of the spring 433b, so that the distance between the movable plate 431 and the pressing plate 432 is increased.

Referring to fig. 1, 8 and 9, in some embodiments, the transport mechanism 500 includes a first cylinder 510, a pusher plate 520, a second cylinder 530, a stop 531 and a storage cartridge 540. The first cylinder 510 is fixed on the support and connected with the push plate 520, a positioning surface 524 is formed on the surface of the push plate 520 in a recessed mode, the first step surface 521 and the second step surface 522 are arranged vertically, for example, the positioning surface 524 is arranged vertically, the first step surface 521 and the second step surface 522 are arranged horizontally, the positioning surface 524 is connected with the first step surface 521 in a bent mode, the first step surface 521 and the second step surface 522 are spaced at a certain distance in the vertical direction, the first step surface 521 can apply a certain supporting force to the end portion of the cap plate 21 in the vertical direction, the positioning surface 524 can apply a certain abutting force to the cap plate 21 in the horizontal direction, and when the first cylinder 510 drives the push plate 520 to slide close to the bearing plate 200, the cap plate 21 can move close to the bearing plate 200 along with the push plate 520 under the action of the positioning surface 524. The second step surface 522 is further provided with protruding strips 523, the protruding strips 523 protrude a certain height relative to the second step surface 522, the number of the protruding strips 523 is two, and the two protruding strips 523 are arranged at intervals. The rib 523 can provide a certain guiding and limiting function for the cap plate 21 to be placed on the push plate 520. The capping device 10 further includes a stopper 600, the stopper 600 is fixed on the bearing plate 200, when the cap plate 21 moving along with the push plate 520 abuts against the stopper 600, the push plate 520 stops moving, at this time, the second step 522 is located between the cap plate 21 and the bearing plate 200, and the cap 20 on the cap plate 21 is located right above the through hole 210 of the bearing plate 200, so that the cap 20 and the through hole 210 form a one-to-one correspondence relationship.

The edge of the cap plate 21 is provided with a notch 22, the second cylinder 530 can drive the blocking member 531 to move downward, and the blocking member 531 can be a cylindrical rod, so that the blocking member 531 is matched with the notch 22, and then the blocking member 531 can apply a certain abutting force to the cap plate 21 in the sliding direction of the push plate 520. When the push plate 520 forms a one-to-one correspondence relationship between the cap 20 and the through hole 210, the first cylinder 510 can drive the push plate 520 to move away from the bearing plate 200, due to the abutting action of the blocking part 531 and the cap plate 21, the cap plate 21 can not move along with the push plate 520, and the cap plate 21 is ensured to be located right above the bearing plate 200, after the first cylinder 510 drives the push plate 520 to rapidly leave the bearing plate 200, the cap plate 21 loses the support of the push plate 520, under the action of gravity, the cap plate 21 falls on the bearing plate 200, and meanwhile, the cap 20 is matched with the through hole 210. Therefore, when all the caps 20 on the cap plate 21 are consumed, a new cap plate 21 carrying the caps 20 can be conveyed to the carrier plate 200 by the push plate 520.

A storage magazine 540 is coupled to the support 100 and is used to store the cap plate 21, the storage magazine 540 being capable of delivering the cap plate 21 onto the push plate 520. Specifically, after the cap plate 21 is conveyed to the carrier plate 200 by the push plate 520, the cap plate 21 does not exist on the push plate 520, and at this time, the storage compartment 540 may supplement the push plate 520 with a new cap plate 21 so that the push plate 520 continuously conveys the cap plate 21 to the carrier plate 200.

The capping device 10 further includes a pushing assembly 700, the pushing assembly 700 includes a pushing cylinder 710, a pushing plate 720 and an output cylinder 730, the pushing cylinder 710 and the output cylinder 730 are connected to the support 100, the pushing plate 720 is connected to the pushing cylinder 710, when the pushing cylinder 710 drives the pushing plate 720 to move, the pushing plate 720 pushes the cap plate 21 from the bearing plate 200 to the output cylinder 730, so that the output cylinder 730 outputs the cap plate 21 with the consumed cap 20 to a designated position.

The operation of the capping device 10 is described below:

in the first step, the cap plate 21 does not exist on the carrier plate 200, so the first cylinder 510 drives the push plate 520 carrying the cap plate 21 to move close to the carrier plate 200, when the cap plate 21 abuts against the limiting member 600, the push plate 520 stops sliding, and at this time, the caps 20 on the cap plate 21 correspond to the through holes 210 one by one. In the second step, the second cylinder 530 drives the blocking member 531 to move downward to match with the notch 22, and the first cylinder 510 drives the push plate 520 to rapidly separate from the bearing plate 200, so that the cap plate 21 cannot leave the bearing plate 200 along with the push plate 520 due to the interference of the blocking member 531 on the cap plate 21. When the push plate 520 is completely separated from the cap plate 21, the cap plate 21 loses the support of the push plate 520, the cap plate 21 falls on the carrier plate 200 by gravity, and the cap 20 is engaged with the through hole 210. At this time, the second cylinder 530 may drive the blocking member 531 to move upward. Thirdly, the power source 310 works to make the sliding seat 300 move along the sliding rail 320 on the support 100, so that the sliding seat 300 drives the whole pressing mechanism 400 to move to the rear of the bearing plate 200, and the pressing rod 440 is ensured to be located right above the first row of through holes 210 at the extreme edge of the rear of the bearing plate 200. Fourth, the driver 410 is operated such that the coupling assembly 420 moves downward along the guide rail 412 near the loading plate 200, and at this time, both the mounting assembly 430 and the pressing rod 440 simultaneously move downward following the coupling assembly 420 until the pressing plate 432 of the mounting assembly 430 is in contact with the loading plate 200. In the fifth step, the driver 410 continues to drive the connecting assembly 420 to move downward, and at this time, the pressing plate 432 stops moving in the vertical direction due to the contact with the bearing plate 200, that is, the pressing plate 432 is in a static state. During the downward movement of the connecting assembly 420, the movable plate 431 drives the pressing rod 440 to continue to move downward, so that the pressing rod 440 extrudes the cap 20 in the through hole 210 out of the through hole 210 to cover the test tube. Obviously, during the downward movement of the movable plate 431, the guide rod 433a slides upward relative to the slide hole 431a, and the spring 433b is compressed to store energy. Through setting up spring 433b, spring 433b can provide certain cushioning effect, avoids the great impact effect of production in the twinkling of an eye of depression bar 440 and the contact of block 20, avoids depression bar 440 to constitute the damage to block 20. Therefore, the first row of caps 20 at the rear edge of the carrier plate 200 is completely consumed, and then the caps 20 in the second row of through holes 210 must be covered on the test tubes, wherein the second row of through holes 210 is adjacent to the first row of through holes 210.

Sixthly, the driver 410 continues to drive the connecting assembly 420 to move upward, so that the pressing plate 432 is released from contact with the supporting plate 200, when the pressing plate 432 is away from the supporting plate 200, the driver 410 stops moving, at this time, the spring 433b extends to release energy, the movable plate 431 stops moving upward and is in a stationary state, and the pressing plate 432 moves downward relative to the movable plate 431, thereby restoring the initial distance between the pressing plate 432 and the movable plate 431. Seventh, the power source 310 operates to make the sliding seat 300 move along the sliding rail 320 on the supporting base 100, so that the sliding seat 300 drives the whole pressing mechanism 400 to move forward for a short distance, and the pressing rod 440 is ensured to be located right above the second row of through holes 210 of the supporting plate 200. In an eighth step, the driver 410 is operated to move the connecting assembly 420 along the guide rail 412 downward to approach the carrier plate 200, as described in connection with the fourth and fifth steps, so as to completely cover the caps 20 in the second row of through-holes 210 on the test tubes.

After the caps 20 in the second row of through holes 210 are completely consumed, referring to the description of the sixth step to the eighth step, the caps 20 in the third row of through holes 210 can be covered on the test tube, and so on, until the caps 20 in the tenth row of through holes 210 are covered on the test tube. When all the caps 20 on the cap plate 21 are completely consumed, the pushing cylinder 710 drives the pushing plate 720 to move, the pushing plate 720 pushes the cap plate 21 from the bearing plate 200 to the output cylinder 730, so that the output cylinder 730 outputs the cap plate 21 with the caps 20 completely consumed to a specified position, that is, the cap plate 21 is removed from the bearing plate 200, so that the conveying mechanism 500 conveys the new cap plate 21 matched with the caps 20 to the bearing plate 200, and the pressing mechanism 400 covers all the caps 20 with the cap plates 21 on the test tubes, therefore, the caps 20 can be continuously covered on the test tubes through the working mode of the production line.

Therefore, by making the pressing mechanism 400 include a plurality of pressing rods 440, when the pressing mechanism 400 works, a plurality of caps 20 can be covered on different test tubes at one time, instead of only one cap 20 can be covered on one test tube at one time, which can greatly improve the working efficiency of the whole capping device 10. Meanwhile, the press-fit mechanism 400 is fixed on the sliding seat 300, and under the condition that the cap 20 and the bearing plate 200 do not need to be moved, the sliding seat 300 drives the press-fit mechanism 400 to move, so that a plurality of caps 20 in other through holes 210 on the bearing plate 200 can be pressed on different test tubes, thereby saving the replacement time of the caps 20 and further improving the working efficiency of the capping device 10. Furthermore, when all the caps 20 on one cap plate 21 are consumed, the conveying mechanism 500 is provided with the storage bin 540, so that a new cap plate 21 carrying the caps 20 can be quickly conveyed onto the carrier plate 200, the waiting time of the pressing mechanism 400 can be eliminated, and the working efficiency of the capping device 10 can also be improved.
