Description

Technical Field

[0001] The present disclosure relates to the field of biomedical devices, and particularly to a wax-sealing mechanism for reagent tube encapsulation and a biomedical reagent production device. Background Art

[0002] Biochemical reagents refer to biological materials or organic compounds related to life science research, as well as reagents for clinical diagnosis and medical research. Due to the broad scope and rapid development of life science, there is a wide variety of such reagents with complex properties. During the production process of biochemical reagents, after the test solution is filled into a test tube, in order to effectively isolate harmful factors such as oxygen, moisture, and microorganisms in the external environment and prevent the reagent from being contaminated, wax-sealing is generally carried out after filling the reagent.

[0003] For example, Chinese Patent with application number CN202111343534.0 discloses a paraffin filling device and filling process applied to the reagent tube encapsulation process, including a gas pressure regulating device, a stainless steel container, a ceramic heating group, a heating tube, a gas solenoid valve, a valve body heating block, and a paraffin valve body. The paraffin is quickly heated and melted by the ceramic heating group and quantitatively filled through the gas solenoid valve.

[0004] However, the structural design of the above paraffin filling device has the following problems during use:

[0005] The above paraffin filling device melts the paraffin through the ceramic heating group and then fills it. However, there is no cooling mechanism after the paraffin is filled into the test tube, and it can only be cooled naturally, so the cooling time is relatively long. On the other hand, the above paraffin filling device has a low degree of automation and cannot perform pipeline filling on test tubes, so the production efficiency is relatively low.

[0006] Therefore, there is an urgent need for a wax-sealing mechanism with high automation and high production efficiency. Utility Model Content

[0032] The present disclosure provides a wax sealing mechanism 10 for reagent tube encapsulation, including a conveying rack 100, a filling assembly 200, a heating assembly 300, a moving scraper assembly 400, a cooling assembly 500 and a bracket 600. A conveyor belt is provided on the conveying rack 100, and the conveyor belt is used to convey test tubes. The heating assembly 300 is used to store and heat paraffin. The bracket 600 is arranged adjacent to the conveying rack 100. The bracket 600 is provided with a first port 610, and the conveying rack 100 is provided with a second port 110. The first port 610 is communicated with the second port 110 so that the bracket 600 and the conveying rack 100 jointly form a moving channel 100a. A part of the structure of the moving scraper assembly 400 is movably arranged in the moving channel 100a. The moving scraper assembly 400 is used to drive the test tube to move in the moving channel 100a. The filling assembly 200 is used to pour the paraffin in the heating assembly 300 into the test tube on the bracket 600. The cooling assembly 500 includes a cooling member 510 and a cooling box 520. The cooling box 520 is arranged adjacent to the conveying rack 100. The cooling member 510 is installed on the cooling box 520, and the cooling port of the cooling box 520 faces the conveyor belt.

[0033] The above wax sealing mechanism 10 for reagent tube encapsulation, the bracket 600 is arranged adjacent to the conveyor rack 100. The bracket 600 is provided with a first port 610, and the conveyor rack 100 is provided with a second port 110 communicating with the first port 610, so that the bracket 600 and the conveyor rack 100 jointly form a moving channel 100a. A part of the moving scraper assembly 400 is movably arranged in the moving channel 100a. When the test tube on the conveyor rack 100 is conveyed to a preset position, the moving scraper assembly 400 pushes the test tube into the bracket 600. At this time, the filling assembly 200 sucks and fills the melted paraffin in the heating assembly 300 into the test tube, and then the moving scraper assembly 400 pushes the test tube back onto the conveyor rack 100. The conveyor rack 100 conveys the filled test tube to the cooling assembly 500. The cooling part 510 works to make the cold air blow towards the test tube through the cooling port of the cooling box 520 to quickly cool the paraffin. Specifically, through the mutual cooperation of the components of the mechanism, the degree of automation of paraffin filling is high, and the paraffin can be quickly cooled, thereby improving the production efficiency.

[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0035] As Figure 1 and Figure 2 As shown, the wax sealing mechanism 10 for reagent tube encapsulation in an embodiment includes a conveyor rack 100, a filling assembly 200, a heating assembly 300, a moving scraper assembly 400, a cooling assembly 500 and a bracket 600. A conveyor belt is provided on the conveyor rack 100, and the conveyor belt is used to convey test tubes. The heating assembly 300 is used to store and heat paraffin. The bracket 600 is arranged adjacent to the conveyor rack 100. The bracket 600 is provided with a first port 610, and the conveyor rack 100 is provided with a second port 110. The first port 610 communicates with the second port 110, so that the bracket 600 and the conveyor rack 100 jointly form a moving channel 100a. A part of the structure of the moving scraper assembly 400 is movably arranged in the moving channel 100a. The moving scraper assembly 400 is used to drive the test tube to move in the moving channel 100a. The filling assembly 200 is used to fill the paraffin in the heating assembly 300 into the test tube on the bracket 600.

[0036] Furthermore, the cooling assembly 500 includes a cooling part 510 and a cooling box 520. The cooling box 520 is arranged adjacent to the conveyor rack 100. The cooling part 510 is installed in the cooling box 520, and the cooling port of the cooling box 520 faces the conveyor belt.

[0037] In this embodiment, the test tube contains reagents and is clamped by a jig. The conveyor belt on the conveyor rack 100 is used to convey the jig and the test tube. The heating assembly 300 is used to heat and hold paraffin so that the paraffin in the heating assembly 300 is in a molten state. When the test tube is conveyed to a preset position, that is, when the test tube reaches the position adjacent to the bracket 600, the conveyor belt stops working at this time, and the moving scraper assembly 400 starts to work to drive the test tube to move in the moving channel 100a, that is, to push the test tube from the conveyor rack 100 into the bracket 600. At this time, the filling assembly 200 works to extract the paraffin in the heating assembly 300 and pour it into the test tube. Then, the moving scraper assembly 400 pushes the test tube in the bracket 600 back onto the conveyor rack 100, and the conveyor belt continues to work to convey the test tube to the position of the cooling assembly 500. The cold air blown by the cooling member 510 blows towards the test tube through the cooling port of the cooling box 520, so that the paraffin in the test tube is quickly cooled and solidified, thereby making the preservation effect of the reagents in the test tube better. Further, the cooling member 510 is a high-power air conditioner or a cold air blower.

[0038] For the above wax sealing mechanism 10 for reagent tube encapsulation, the bracket 600 is arranged adjacent to the conveyor rack 100. The bracket 600 is provided with a first port 610, and the conveyor rack 100 is provided with a second port 110 communicated with the first port 610, so that the bracket 600 and the conveyor rack 100 jointly form a moving channel 100a. A part of the moving scraper assembly 400 is movably arranged in the moving channel 100a. When the test tube on the conveyor rack 100 is conveyed to the preset position, the moving scraper assembly 400 pushes the test tube into the bracket 600. At this time, the filling assembly 200 sucks and pours the paraffin that has been heated and melted in the heating assembly 300 into the test tube. Then, the moving scraper assembly 400 pushes the test tube back onto the conveyor rack 100, and the conveyor rack 100 conveys the test tube that has been filled to the cooling assembly 500. The cooling member 510 works to make the cold air blow towards the test tube through the cooling port of the cooling box 520 to quickly cool the paraffin. Specifically, through the mutual cooperation of the components of the mechanism, the degree of automation of paraffin filling is high, and the paraffin can be quickly cooled, thereby improving the production efficiency.

[0039] Such as Figure 2 and Figure 3As shown, in one embodiment, the movable scraper assembly 400 includes a first horizontal driving member 410, a first mounting bracket 420, and a scraper 430. The first mounting bracket 420 is disposed adjacent to the bracket 600. The first horizontal driving member 410 is mounted on the first mounting bracket 420. The power output end of the first horizontal driving member 410 is fixedly connected to the scraper 430. A part of the scraper 430 is located within the moving channel 100a, so that the scraper 430 drives the test tube to move along the moving channel 100a. In this embodiment, the first horizontal driving member 410 is a motor or a cylinder. The first horizontal driving member 410 drives the scraper 430 to perform a horizontal movement within the moving channel 100a to push the test tube from the transfer rack 100 into the bracket 600, or to push the test tube in the bracket 600 back to the transfer rack 100.

[0040] As Figure 2 shown, in one embodiment, a guide rail 421 is provided on the first mounting bracket 420. A guide groove is formed in the scraper 430. A part of the guide rail 421 is embedded in the guide groove, so that the scraper 430 is slidably connected to the first mounting bracket 420. In this embodiment, the first horizontal driving member 410 drives the scraper 430 to move along the extending direction of the guide rail 421, so that the fixing effect of the scraper 430 is better.

[0041] As Figure 3 shown, in one embodiment, clamping posts 431 protrude from both sides of the scraper 430. The clamping posts 431 extend into the moving channel 100a. The two clamping posts 431 are used to clamp the test tube. In this embodiment, when the test tube on the conveyor belt moves to a preset position, the conveyor belt stops working. At this time, the test tube is located between the two clamping posts 431 to clamp the test tube. The first horizontal driving member 410 drives the scraper 430 to move, and the two clamping posts 431 drive the test tube to move along the moving channel 100a.

[0042] As Figure 2 and Figure 3 shown, in one embodiment, the number of the second ports 110 is two. The two second ports 110 are respectively disposed on both sides of the transfer rack 100. The distance between the two second ports 110 is equal to the distance between the two clamping posts 431. It can be understood that if the distance between the two second ports 110 is greater than the distance between the two clamping posts 431, the two clamping posts 431 will interfere with the transmission of the test tube when the conveyor belt conveys the test tube; if the distance between the two second ports 110 is less than the distance between the two clamping posts 431, the two clamping posts 431 cannot closely fit the test tube, and thus cannot clamp the test tube between the two clamping posts 431.

[0043] As Figure 4As shown, in one embodiment, the filling assembly 200 includes a second mounting bracket 210, a second horizontal driving member 220, a vertical driving member 230, a straw 240, and an air pump 250. The second mounting bracket 210 is disposed adjacent to the bracket 600. The second horizontal driving member 220 is mounted on the second mounting bracket 210. The power output end of the second horizontal driving member 220 is connected to the vertical driving member 230. The power output end of the vertical driving member 230 is connected to the air pump 250. The air pump 250 is connected to the straw 240. In this embodiment, the second horizontal driving member 220 indirectly drives the straw 240 to move horizontally, so that the straw 240 moves from above the heating assembly 300 to above the bracket 600. The vertical driving member 230 drives the straw 240 to move in the vertical direction, so that the straw 240 can move up and down relative to the heating assembly 300 or the bracket 600. In this way, the multi-dimensional movement of the straw 240 is achieved, and the straw 240 fills the paraffin in the heating assembly 300 into the test tubes on the bracket 600. Further, the air pump 250 drives the straw 240 to form positive pressure or negative pressure to suck or push out the molten paraffin. The second horizontal driving member 220 and the vertical driving member 230 are cylinders or motors.

[0044] As Figure 4 shown, in one embodiment, the number of the straws 240 is multiple, and the multiple straws 240 are respectively connected to the air pump 250. It can be understood that the multiple test tubes correspond to the test tubes in the fixture one by one, so that multiple test tubes can be filled with paraffin simultaneously, improving the production efficiency.

[0045] As Figure 4 shown, in one embodiment, the heating assembly 300 includes a heating member 320 and a heating box 310. The heating box 310 is disposed adjacent to the second mounting bracket 210. The heating box 310 is used to hold paraffin. The heating member 320 is connected to the heating box 310. In this embodiment, the heating member 320 is a heating rod or a heating tube. The paraffin is placed in the heating box 310, and the heating member 320 heats the heating box 310 to increase the temperature of the heating box 310, thereby melting the paraffin.

[0046] As Figure 1 shown, in one embodiment, the number of the cooling members 510 is multiple, and the multiple cooling members 510 are spaced apart and disposed in the cooling box 520. In this embodiment, the multiple cooling members 510 are spaced apart in the cooling box 520, so that the cold air output by the cooling box 520 has a lower temperature and a greater wind speed, and thus the paraffin in the test tube cools faster.

[0047] The present application further provides a biological reagent production device, including the wax sealing mechanism 10 for reagent tube encapsulation described in any of the above embodiments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] In the above wax sealing mechanism 10 for reagent tube encapsulation, the bracket 600 is arranged adjacent to the transfer rack 100. The bracket 600 is provided with a first port 610, and the transfer rack 100 is provided with a second port 110 communicating with the first port 610, so that the bracket 600 and the transfer rack 100 jointly form a moving channel 100a. A part of the moving scraper assembly 400 is movably arranged in the moving channel 100a. When the test tube on the transfer rack 100 is transferred to a preset position, the moving scraper assembly 400 pushes the test tube into the bracket 600. At this time, the filling assembly 200 sucks and fills the melted paraffin in the heating assembly 300 into the test tube, and then the moving scraper assembly 400 pushes the test tube back onto the transfer rack 100. The transfer rack 100 transfers the filled test tube to the cooling assembly 500. The cooling member 510 works to make the cold air blow towards the test tube through the cooling port of the cooling box 520 to quickly cool the paraffin. Specifically, through the mutual cooperation of the components of the mechanism, the automation degree of paraffin filling is high, and the paraffin can be quickly cooled, thereby improving the production efficiency.

[0050] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
