Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a capping device. Background Art

[0002] In the field of medical devices, a capping device is used to cooperate a cap and a test tube, so that the cap covers the opening of the test tube, thereby sealing the test tube and preventing external dust and droplets from invading the lumen of the test tube. However, for traditional capping devices, the capping device can only cap one cap with a test tube at a time, seriously affecting work efficiency. Therefore, there is an urgent need to provide a capping device that can improve work efficiency. Summary of the Invention

[0030] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "inner", "outer", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0032] Referring simultaneously to Figure 1 , Figure 2 and Figure 3 , a gland device 10 provided by an embodiment of the present invention includes a support frame 100, a bearing plate 200, a sliding seat 300, a power source 310, a slide rail 320, a pressing mechanism 400, and a conveying mechanism 500. The pressing mechanism 400 includes a driver 410, a connecting component 420, a mounting component 430, and a pressing rod 440.

[0033] Referring simultaneously to Figure 2 , Figure 6 and Figure 7 , in some embodiments, the bearing plate 200 can be a rectangular plate-like structure. A plurality of through holes 210 can be formed in the bearing plate 200. The through holes 210 penetrate through the upper and lower surfaces of the bearing plate 200. The plurality of through holes 210 are arranged in a matrix on the bearing plate 200. For example, the number of through holes 210 in a bearing plate 200 can be one hundred. One hundred through holes 210 are arranged in ten rows and ten columns. In other words, the through holes 210 are arranged in ten rows on the bearing plate 200, and each row includes ten through holes 210.

[0034] In some embodiments, the support 100 is connected to the bearing plate 200, and the bearing plate 200 is horizontally arranged. The slide rail 320 and the power source 310 are both arranged on the support 100. The slide rail 320 extends in the horizontal direction. The power source 310 can be a motor module. One end of the sliding seat 300 is slidably engaged with the slide rail 320, and the other end of the sliding seat 300 is connected to the power source 310. When the power source 310 operates, the power source 310 can drive the sliding seat 300 to reciprocate along the slide rail 320. The pressing mechanism 400 is fixed on the sliding seat 300, so the entire pressing mechanism 400 can reciprocate along the extension direction of the slide rail 320 following the sliding seat 300.

[0035] Referring simultaneously to Figure 3, Figure 4 and Figure 5 , the driver 410 of the lamination mechanism 400 can be a lead screw motor, that is, the driver 410 includes a driving part 411, a guide rail 412, an output shaft 413 and a slider 421. The guide rail 412 extends in the vertical direction, and the guide rail 412 is connected to the driving part 411. The slider 421 is slidably engaged with the guide rail 412, and the connecting assembly 420 is fixed on the slider 421. The connecting assembly 420 slides along the guide rail 412 following the slider 421. The output shaft 413 is connected to the driving part 411 and passes through the slider 421. When the driving part 411 drives the output shaft 413 to rotate, the output shaft 413 will drive the slider 421 to move up and down along the guide rail 412, thereby converting the rotational motion of the output shaft 413 into a linear motion of the connecting assembly 420. For example, when the driving part 411 drives the output shaft 413 to rotate clockwise, the output shaft 413 drives the slider 421 and the connecting assembly 420 to slide down along the guide rail 412; when the driving part 411 drives the output shaft 413 to rotate counterclockwise, the output shaft 413 drives the slider 421 and the connecting assembly 420 to slide up along the guide rail 412.

[0036] In some embodiments, the connecting assembly 420 is connected to enclose a receiving cavity 422e. The slider 421 is connected to the connecting assembly 420 such that the slider 421 is at least partially received in the receiving cavity 422e. Specifically, the connecting assembly 420 includes a bottom wall 422a, a first side wall 422b, a second side wall 422c and a third side wall 422d. The outlines of the bottom wall 422a and the third side wall 422d are generally rectangular, and the shapes of the first side wall 422b and the second side wall 422c are similar and their outlines are generally triangular. The first side wall 422b, the second side wall 422c and the third side wall 422d are all connected to the same side of the bottom wall 422a. The first side wall 422b and the second side wall 422c are respectively connected to two opposite long sides on the bottom wall 422a. The third side wall 422d is connected between the first side wall 422b and the second side wall 422c. The third side wall 422d is connected to one of the short sides of the bottom wall 422a. At the same time, one end of the third side wall 422d is connected to the first side wall 422b, and the other end of the third side wall 422d is connected to the second side wall 422c. Therefore, the cross-section of the receiving cavity 422e is generally a U-shaped structure with a flat bottom. The slider 421 is stacked on the surface of the bottom wall 422a, and the slider 421 and the bottom wall 422a can be fixedly connected by bolts. The mounting assembly 430 is located outside the receiving cavity 422e of the connecting assembly 420. The mounting assembly 430 is connected to the third side wall 422d, and the mounting assembly 430 and the third side wall 422d can also be fixedly connected by bolts.

[0037] By providing a receiving cavity 422e on the connecting component 420, on the one hand, at least a part of the slider 421 is received in the receiving cavity 422e of the connecting component 420, so that the slider 421 can make full use of the installation space of the receiving cavity 422e, thereby reducing the volume of the entire connecting component 420. On the other hand, the receiving cavity 422e can provide an avoidance space for the installation of the connecting component 420, enabling the connecting component 420 to effectively connect with the slider 421 by eliminating interference from other components.

[0038] In some embodiments, the mounting assembly 430 includes a movable plate 431, a pressing plate 432, and a guiding member 433. Both the movable plate 431 and the pressing plate 432 are generally rectangular parallelepiped structures with a relatively large length. The movable plate 431 can be fixed to the third side wall 422d of the connecting component 420 by bolts. The pressing plate 432 is located directly below the movable plate 431, that is, the movable plate 431 and the pressing plate 432 are spaced apart in the vertical direction, creating a certain gap between them. The upper end of the pressure rod 440 is fixed to the movable plate 431. For example, ten pressure rods 440 can be fixed to the movable plate 431. The pressure rods 440 are evenly spaced in a straight line in the horizontal direction, and the distance between adjacent pressure rods 440 is equal to the distance between two through holes 210 on the bearing plate 200. When the pressure rods 440 are at a suitable position above the bearing plate 200, the orthographic projections of all the pressure rods 440 on the bearing plate 200 respectively fall into different through holes 210, enabling the pressure rods 440 to form a one-to-one correspondence with the through holes 210. When the movable plate 431 drives the pressure rods 440 to move downward, ten pressure rods 440 can be inserted into a row of through holes 210 on the bearing plate 200, and the number of through holes 210 in a row is also ten. After ten pressure rods 440 are simultaneously inserted into ten through holes 210, ten caps 20 can be simultaneously covered on ten test tubes. A through hole 432a is provided on the pressing plate 432, and the lower end of the pressure rod 440 is inserted into the through hole 432a to achieve a sliding fit between the pressure rod 440 and the through hole 432a. During operation, the pressing plate 432 is used to press against the bearing plate 200.

[0039] In some embodiments, the guide member 433 includes a guide rod 433a and a spring 433b. A sliding hole 431a is formed in the movable plate 431. The lower end of the guide rod 433a can be fixed to the end portion on the pressing plate 432. The spring 433b is pressed between the movable plate 431 and the pressing plate 432. At the same time, the spring 433b can be a cylindrical spring, and the spring 433b is sleeved outside the guide rod 433a. The upper end of the spring 433b abuts against the movable plate 431, and the lower end of the spring 433b abuts against the pressing plate 432. A sliding hole 431a is formed in the movable plate 431, and the guide rod 433a is inserted into the sliding hole 431a, so as to realize the sliding fit relationship between the guide rod 433a and the sliding hole 431a. During the working process, the guide rod 433a is fixedly connected to the pressing plate 432 so that their relative positions remain unchanged, and the pressing rod 440 is fixedly connected to the movable plate 431 so that their relative positions remain unchanged. When the pressing plate 432 is in contact with the bearing plate 200, when the movable plate 431 moves downward 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 decreases, and the pressing rod 440 slides downward relative to the through hole 432a on the pressing plate 432. At the same time, the guide rod 433a moves upward relative to the sliding hole 431a on the movable plate 431. On the contrary, when the pressing plate 432 stops contacting the bearing plate 200, the spring 433b releases energy and elongates. Under the thrust of the spring 433b, the pressing plate 432 moves downward relative to the movable plate 431, and the guide rod 433a moves downward relative to the sliding hole 431a on the movable plate 431.

[0040] In some embodiments, the guide rod 433a is generally a cylindrical rod. The guide rod 433a includes a limiting portion 433c and a guiding portion 433d. The limiting portion 433c is connected to the upper end of the guiding portion 433d. The cross-sectional dimension of the guiding portion 433d can be slightly smaller than the cross-sectional dimension of the sliding hole 431a, so that the guiding portion 433d and the sliding hole 431a maintain a clearance fit relationship, enabling the guiding portion 433d to slide smoothly relative to the sliding hole 431a. At the same time, the cross-sectional dimension of the limiting portion 433c is larger than the cross-sectional dimension of the sliding hole 431a, so that the limiting portion 433c cannot enter the sliding hole 431a. In fact, the limiting portion 433c plays a good limiting function to maintain the maximum distance between the movable plate 431 and the pressing plate 432. When the spring 433b releases energy and pushes 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 gradually increases. At the same time, the guiding portion 433d of the guide rod 433a moves downward relative to the sliding hole 431a on the movable plate 431, so that the guiding portion 433d drives the limiting portion 433c to move downward relative to the sliding hole 431a as well. When the limiting portion 433c abuts against the movable plate 431 and cannot pass through the sliding hole 431a, due to the interference of the limiting portion 433c, the pressing plate 432 stops moving downward relative to the movable plate 431. At this time, the distance between the movable plate 431 and the pressing plate 432 is the largest and cannot continue to increase.

[0041] The number of the guide rods 433a can 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 also four, and one spring 433b is sleeved on each guide rod 433a. By providing four guide rods 433a, the stability and accuracy of the relative movement between the pressing plate 432 and the movable plate 431 can be ensured. Of course, the numbers of the guide rods 433a and the springs 433b can also be appropriately increased. When the number of the springs 433b increases, the restoring force of the movement of the pressing plate 432 relative to the movable plate 431 can be increased.

[0042] In fact, when the pressing plate 432 contacts the bearing plate 200, the pressing plate 432 stops moving in the vertical direction. At this time, through the sliding fit relationship between the pressing rod 440 and the through hole 432a, and the sliding fit relationship between the guide rod 433a and the sliding hole 431a, the movable plate 431 can move downward relative to the stationary pressing plate 432, thereby reducing the distance between the movable plate 431 and the pressing plate 432. At the same time, when the pressing rod 440 rises a short distance following the movable plate 431, under the elastic force of the spring 433b, the pressing plate 432 abuts against the cap plate 21, preventing the cap plate 21 from rising with the pressing rod 440 and detaching from the bearing plate 200. When the rising distance of the movable plate 431 continues to increase, driving the pressing plate 432 to leave the cap plate 21, under the elastic force of the spring 433b, the pressing plate 432 moves downward relative to the movable plate 431, thereby increasing the distance between the movable plate 431 and the pressing plate 432.

[0043] Refer to 1, Figure 8 and Figure 9 , in some embodiments, the conveying mechanism 500 includes a first cylinder 510, a push plate 520, a second cylinder 530, a blocking member 531, and a storage bin 540. The first cylinder 510 is fixed on the support and connected to the push plate 520. A positioning surface 524, a first step surface 521, and a second step surface 522 are recessed on the surface of the push plate 520. For example, the positioning surface 524 is vertically arranged, the first step surface 521 and the second step surface 522 are both horizontally arranged, the positioning surface 524 is bent and connected to the first step surface 521, the first step surface 521 and the second step surface 522 are spaced apart by a certain distance in the vertical direction. The first step surface 521 can exert a certain supporting force on the end of the cap plate 21 in the vertical direction, and the positioning surface 524 can exert a certain abutting force on the cap plate 21 in the horizontal direction. When the first cylinder 510 drives the push plate 520 to slide close to the bearing plate 200, through the action of the positioning surface 524, the cap plate 21 can move close to the bearing plate 200 together with the push plate 520. A rib 523 is also provided on the second step surface 522. The rib 523 protrudes a certain height relative to the second step surface 522, and the number of ribs 523 is also two, and the two ribs 523 are spaced apart. The rib 523 can play a certain guiding and limiting role for the placement of the cap plate 21 on the push plate 520. The capping device 10 further includes a limiting member 600, and the limiting member 600 is fixed on the bearing plate 200. When the cap plate 21 following the movement of the push plate 520 abuts against the limiting member 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 just located directly 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.

[0044] Notches 22 are formed on the edge of the cap plate 21. The second cylinder 530 can drive the blocking member 531 to move downward. The blocking member 531 can be a cylindrical rod, so that the blocking member 531 cooperates 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 makes the cap 20 and the through hole 210 form a one-to-one correspondence, the first cylinder 510 can drive the push plate 520 to move away from the bearing plate 200. Due to the abutting action between the blocking member 531 and the cap plate 21, the cap plate 21 cannot move with the push plate 520, ensuring that the cap plate 21 is located directly above the bearing plate 200. When the first cylinder 510 drives the push plate 520 to quickly 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. At the same time, the cap 20 cooperates 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 bearing plate 200 through the push plate 520.

[0045] The storage bin 540 is connected to the support 100 and is used to store the cap plates 21. The storage bin 540 can convey the cap plates 21 onto the push plate 520. Specifically, when the push plate 520 conveys the cap plate 21 to the bearing plate 200, there is no cap plate 21 on the push plate 520. At this time, the storage bin 540 can supply a new cap plate 21 to the push plate 520 so that the push plate 520 can continuously convey the cap plates 21 to the bearing plate 200.

[0046] The capping device 10 further includes a pushing component 700. The pushing component 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 both 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 can output the cap plate 21 with the caps 20 consumed to a designated position.

[0047] The working principle of the capping device 10 is introduced below:

[0048] First step: There is no cap plate 21 on the carrier plate 200. Therefore, the first air cylinder 510 drives the push plate 520 carrying the cap plate 21 to move closer to the carrier plate 200. When the cap plate 21 presses against the limiting member 600, the push plate 520 stops sliding. At this time, the caps 20 on the cap plate 21 correspond to the through holes 210 one by one. Second step: The second air cylinder 530 drives the blocking member 531 to move downward to cooperate with the notch 22, and the first air cylinder 510 drives the push plate 520 to quickly leave the carrier plate 200. Due to the interference of the blocking member 531 on the cap plate 21, the cap plate 21 cannot follow the push plate 520 to leave the carrier plate 200. When the push plate 520 completely leaves the cap plate 21, the cap plate 21 loses the support of the push plate 520. Under the action of gravity, the cap plate 21 falls on the carrier plate 200, and the cap 20 cooperates with the through hole 210. At this time, the second air cylinder 530 can drive the blocking member 531 to move upward. Third step: The power source 310 works, so that the sliding seat 300 moves along the slide rail 320 on the support 100, so that the sliding seat 300 drives the entire pressing mechanism 400 to move to the rear of the carrier plate 200, ensuring that the pressing rod 440 is directly above the first row of through holes 210 at the rearmost edge of the carrier plate 200. Fourth step: The driver 410 works, so that the connecting component 420 moves downward along the guide rail 412 closer to the carrier plate 200. At this time, both the mounting component 430 and the pressing rod 440 move downward along with the connecting component 420 until the pressing plate 432 of the mounting component 430 contacts the carrier plate 200. Fifth step: The driver 410 continues to drive the connecting component 420 to move downward. At this time, the pressing plate 432 stops moving in the vertical direction because it contacts the carrier plate 200, that is, the pressing plate 432 is in a static state. During the downward movement of the connecting component 420, the movable plate 431 drives the pressing rod 440 to continue moving downward, so that the pressing rod 440 extrudes the cap 20 in the through hole 210 from 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 sliding hole 431a, and the spring 433b is compressed to store energy. By setting the spring 433b, the spring 433b can provide a certain buffering effect, avoiding a large impact force when the pressing rod 440 contacts the cap 20, and avoiding damage to the cap 20 by the pressing rod 440. Therefore, the caps 20 in the first row at the rearmost edge of the carrier plate 200 have been consumed. Next, the caps 20 in the second row of through holes 210 must be covered on the test tubes. The second row of through holes 210 is adjacent to the first row of through holes 210.

[0049] Step 6: The driver 410 continues to drive the connecting component 420 to move upward, so that the pressing plate 432 releases the contact with the carrier plate 200. When the pressing plate 432 leaves the carrier 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 remains stationary, and the pressing plate 432 moves downward relative to the movable plate 431, so as to restore the initial distance between the pressing plate 432 and the movable plate 431. Step 7: The power source 310 works, so that the sliding seat 300 moves along the slide rail 320 on the support 100, so that the sliding seat 300 drives the entire pressing mechanism 400 to move forward a small distance, ensuring that the pressing rod 440 is directly above the second row of through holes 210 of the carrier plate 200. Step 8: The driver 410 works, so that the connecting component 420 moves downward along the guide rail 412 and approaches the carrier plate 200. Referring to the relevant descriptions in the above-mentioned Step 4 and Step 5, all the caps 20 in the second row of through holes 210 are covered on the test tubes.

[0050] When all the caps 20 in the second row of through holes 210 are consumed, referring to the relevant descriptions in the above-mentioned Step 6 to Step 8, the caps 20 in the third row of through holes 210 can be covered on the test tubes, and so on, until the caps 20 in the tenth row of through holes 210 are covered on the test tubes. When all the caps 20 on the cap plate 21 are consumed, the pushing cylinder 710 drives the pushing plate 720 to move, and the pushing plate 720 pushes the cap plate 21 from the carrier plate 200 to the output cylinder 730, so that the output cylinder 730 outputs the cap plate 21 with all the caps 20 consumed to a specified position, that is, removes the cap plate 21 from the carrier plate 200, so that the conveying mechanism 500 conveys a new cap plate 21 with a cap 20 to the carrier plate 200, so that the pressing mechanism 400 can cover all the caps 20 with the new cap plate 21 on the test tubes. Therefore, through the working mode of the assembly line, the caps 20 can be continuously covered on the test tubes.

[0051] Therefore, by making the pressing mechanism 400 include a plurality of pressing rods 440, when the pressing mechanism 400 operates, a plurality of caps 20 can be respectively capped on different test tubes at one time, rather than only one cap 20 can be capped on one test tube at a time, which can greatly improve the working efficiency of the entire capping device 10. At the same time, the pressing mechanism 400 is fixed on the sliding seat 300. Without moving the cap 20 and the carrier plate 200, by driving the pressing mechanism 400 to move through the sliding seat 300, a plurality of caps 20 in other through holes 210 on the carrier plate 200 can be pressed on different test tubes, thereby saving the replacement time of the cap 20 and further improving the working efficiency of the capping device 10. Furthermore, when all the caps 20 on a cap plate 21 are consumed, the conveying mechanism 500 is equipped with a storage bin 540, which can quickly convey the new cap plate 21 carrying the caps 20 to the carrier plate 200, eliminating the waiting time of the pressing mechanism 400 and also improving the working efficiency of the capping device 10.
