[0003] In the prior art, a tray-type test tube sealing device is used to seal test tube specimens. This tray-type test tube sealing device includes a tray and a sealing machine, and the tray has multiple test tube holders. When sealing test tubes, multiple test tubes to be sealed are placed sequentially in the test tube holders on the tray, and the tray is moved under the sealing machine with the open end of the test tube facing the sealing machine. The sealing machine seals multiple test tubes on the tray simultaneously.

[0004] However, the aforementioned tray-type test tube sealing device needs to seal multiple test tubes at the same time, which makes the test tube samples collected earlier more prone to deterioration or evaporation. Furthermore, when removing the seals of the test tubes during re-examination, the seals need to be torn off manually, which is quite inconvenient. Summary of the Invention

[0005] This application provides a test tube sealing film processing device to solve the problems of the above-mentioned tray-type test tube sealing device, which requires sealing multiple test tubes at the same time, making the test tube samples collected earlier more prone to deterioration or evaporation, and requiring manual tearing of the seals to remove the test tubes during re-examination, which is inconvenient.

[0013] In some technical solutions of the above-mentioned test tube sealing film processing device, the sealing film processing mechanism includes: a driving component, a heating element, and a shaping block. The shaping block is located on the periphery of the heating element, and the driving component is connected to the shaping block. The driving component drives the heating element to move by driving the shaping block, so that the heating element transports the sealing film on the temporary storage stage to the test tube and contacts the sealing film on the test tube. The heating element is used to melt the solid adhesive on the sealing film to fix the sealing film to the test tube. The shaping block moves relative to the heating element to fix the sealing film on the periphery of the heating element to the test tube.

[0050] Unless otherwise stated, the term "multiple" means two or more.

[0051] All test tube specimens in medical laboratories should be sealed to prevent them from deteriorating or evaporating. When retesting later, the test tube specimens need to be unsealed and tested again.

[0052] In existing technologies, sealing test tube specimens typically employs a tray-type test tube sealing device. This device includes a tray and a sealing machine. The tray has multiple spaced-apart test tube holders to hold the test tubes, and the sealing machine seals each test tube on the holder. To seal the test tubes, multiple test tubes are placed sequentially in the holders, and the holders are moved below the sealing machine with the open end of the test tube facing it. The sealing machine then seals the test tubes. However, the tray-type test tube sealing device requires sealing multiple test tubes simultaneously. In practice, test tube specimens are usually collected manually, and collecting multiple specimens takes a considerable amount of time. This makes the earlier collected specimens more susceptible to spoilage or evaporation. Furthermore, removing the seals for re-examination requires manual tearing, which is inconvenient.

[0053] Based on this, this application provides a device for processing test tube sealing films, including a sealing film conveying mechanism, a test tube conveying mechanism, and a sealing film processing mechanism. The sealing film conveying mechanism is used to convey the sealing film, the test tube conveying mechanism is used to convey a single test tube to the sealing film processing mechanism, and the sealing film processing mechanism is used to cover the test tube with the sealing film or peel off the sealing film from the test tube. The sealing film processing mechanism processes a single test tube at a time, allowing for timely sealing of the test tube specimen after collection to prevent spoilage or evaporation. Furthermore, the sealing film can be easily peeled off the test tube by the sealing film processing mechanism, making the operation convenient.

[0054] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0055] Reference Figure 1 , Figure 2 and Figure 5This application provides a device for processing test tube sealing film, including: a sealing film conveying mechanism 100, a test tube conveying mechanism 200, and a sealing film processing mechanism 300. The sealing film conveying mechanism 100 includes a placement rack 110 and a temporary storage table 160. The sealing film is placed on the placement rack 110 and can be conveyed to the temporary storage table 160. The test tube conveying mechanism 200 includes a rotating rack 210, a first detection element 230, and a plurality of test tube clamps 220. Each test tube clamp 220 is located on the rotating rack 210 and is used to support test tubes 222. The rotating rack 210 drives each test tube clamp 220 to rotate sequentially to below the sealing film processing mechanism 300. The first detection element 230 is located on one side of the rotating rack 210 and is used to detect whether the test tube 222 corresponding to the first detection element 230 is covered with a sealing film.

[0056] The sealing film processing mechanism 300 is configured to, when the test tube 222 located below the sealing film processing mechanism 300 is not covered with a sealing film, transport the sealing film on the temporary storage stage 160 and cover the test tube 222; when the test tube 222 located below the sealing film processing mechanism 300 is covered with a sealing film, peel the sealing film off the test tube 222.

[0057] The sealing film has a solid adhesive to adhere it to the test tube 222, thereby sealing the test tube 222. For example, the sealing film is an aluminum film, which is lightweight and has good barrier and light-blocking properties, effectively preventing the test tube specimen from deteriorating or evaporating.

[0058] The temporary storage table 160 is located on one side of the rotating frame 210 and close to the sealing film processing mechanism 300 so that the sealing film processing mechanism 300 can obtain the sealing film on the temporary storage table 160.

[0059] The rotating frame 210 is circular, and each test tube clamp 220 is evenly arranged along the circumferential contour of the rotating frame 210. The test tube clamp 220 is fixedly connected to the rotating frame 210.

[0060] The first detection element 230 is located above the test tube 222 to detect whether the test tube 222 is covered with a sealing film. For example, the first detection element 230 is a laser detector, which does not need to contact the test tube 222 to avoid affecting the rotation of the test tube 222 by the rotating frame 210.

[0061] In some embodiments, the number of test tube clamps 220 on the rotating frame 210 is four, and each test tube clamp 220 is evenly arranged on the rotating frame 210. It can be understood that the test tube 222 corresponding to the first detection element 230 is opposite to the test tube clamp 220 below the sealing film processing mechanism 300, and the rotating frame 210 can rotate 180° to drive the test tube 222 corresponding to the first detection element 230 to rotate below the sealing film processing mechanism 300.

[0062] In some embodiments, the test tube sealing film processing mechanism includes a support base 400, and the sealing film conveying mechanism 100, the test tube conveying mechanism 200 and the sealing film processing mechanism 300 are all fixedly connected to the support base 400. The support base 400 is used to support the sealing film conveying mechanism 100, the test tube conveying mechanism 200 and the sealing film processing mechanism 300.

[0063] In practice, when the first detection element 230 detects that the test tube 222 is not covered with a sealing film, the rotating frame 210 rotates to rotate the test tube 222 to a position below the sealing film processing mechanism 300. The sealing film processing mechanism 300 then transports the sealing film from the temporary storage table 160 and covers the test tube 222. When the first detection element 230 detects that the test tube 222 is covered with a sealing film, the rotating frame 210 rotates to rotate the test tube 222 to a position below the sealing film processing mechanism 300, which then peels off the sealing film from the test tube 222.

[0064] The test tube sealing film processing device provided in this application embodiment provides a sealing film to the sealing film processing mechanism 300 by setting a sealing film conveying mechanism 100; by setting a rotating frame 210, and setting multiple test tube clamps 220 on the rotating frame 210, the rotating frame 210 rotates each test tube 222 sequentially to the bottom of the sealing film processing mechanism 300, and the sealing film processing mechanism 300 sequentially covers each test tube 222 with a sealing film. After collecting the test tube specimen, the test tube 222 can be sealed in time to prevent the test tube specimen from deteriorating or evaporating. At the same time, the sealing film processing mechanism 300 can also peel off the sealing film on the test tube 222, which is convenient for later review.

[0065] Reference Figure 2 and Figure 5 In some embodiments, the test tube delivery mechanism 200 further includes a second detection element 240, which is located on one side of the rotating frame 210 and is opposite to the sealing film processing mechanism 300. The second detection element 240 is used to detect whether there is a test tube 222 in the test tube clamp 220 corresponding to the second detection element 240.

[0066] The second detection element 240 is located on one side of the corresponding test tube clamp 220 to facilitate the detection of whether there is a test tube 222 inside the test tube clamp 220.

[0067] In a specific implementation, the second detection element 240 detects whether there is a test tube 222 in the corresponding test tube clamp 220. If the second detection element 240 detects that there is a test tube 222 to be processed by the sealing film processing mechanism 300 in the test tube clamp 220, the rotating frame 210 drives the test tube 222 to rotate to below the first detection element 230.

[0068] For example, the second detection element 240 is a laser detector, which has high detection accuracy.

[0069] In a specific implementation, the test tube delivery mechanism 200 also includes a robotic arm located on one side of the second detection element 240. The robotic arm is used to place test tubes 222 to be covered with a sealing film or test tubes 222 to be peeled off from the test tube clamp 220 corresponding to the second detection element 240, or to remove test tubes 222 with the sealing film covered or peeled off from the test tube clamp 220 corresponding to the second detection element 240.

[0070] The robotic arm is located on one side of the rotating frame 210. The robotic arm is used to place the test tubes 222 to be processed by the sealing film processing mechanism 300 on the rotating frame 210, or to remove the test tubes 222 that have been processed by the sealing film processing mechanism 300 from the rotating frame 210, so as to improve the automation of the processing process, reduce manual operation, and achieve higher efficiency.

[0071] For example, the rotating frame 210 has an inlet and outlet, and the second detection element 240 is located on one side of the inlet and outlet. When the robot places the test tube 222 to be covered with a sealing film or the test tube 222 to be peeled off with a sealing film into the test tube clamp 220 at the inlet and outlet, the second detection element 240 detects that the test tube 222 is in the test tube clamp 220 at the inlet and outlet, and the rotating frame 210 rotates to move the test tube 222 away from the inlet and outlet. After the test tube 222 has been covered or peeled off with a sealing film, the rotating frame 210 rotates to move the test tube 222 to the inlet and outlet, the second detection element 240 detects that the test tube 222 is in the test tube clamp 220 at the inlet and outlet, and the robot removes the test tube 222 from the test tube clamp 220.

[0072] Reference Figure 5 In a specific implementation, the test tube clamp 220 includes at least three spaced elastic elements 221, and each elastic element 221 together clamps the test tube 222.

[0073] The elastic element 221 can be a plastic sheet or a metal sheet. Multiple elastic elements 221 together clamp the test tube 222. The elasticity of the elastic elements 221 allows the test tube clamp 220 to support and fix test tubes 222 of different diameters. The test tube clamp 220 has a wide range of applications.

[0074] When test tube 222 is inserted into test tube clamp 220, each elastic element 221 deforms. The elasticity of each elastic element 221 causes the elastic element 221 to fit tightly against the outer wall of test tube 222, thus supporting test tube 222.

[0075] For example, there are four elastic elements 221, each elastic element 221 is evenly arranged around the periphery of the test tube 222. The elastic element 221 has a protrusion for abutting against the test tube 222.

[0076] Reference Figure 1 , Figure 5 and Figure 6 In a specific implementation, the test tube delivery mechanism 200 further includes a clamping assembly 250, which includes a first clamping member 251 and a second clamping member 252 disposed opposite to each other. At least one of the first clamping member 251 and the second clamping member 252 moves relative to the other so that the first clamping member 251 and the second clamping member 252 jointly clamp the test tube 222 below the sealing film processing mechanism 300.

[0077] The clamping assembly 250 is located below the sealing film processing mechanism 300, and both the first clamping member 251 and the second clamping member 252 are located above the test tube clamp 220. The clamping assembly 250 is used to fix the test tube 222 to prevent the test tube 222 from moving when the sealing film processing mechanism 300 covers the test tube 222 with the sealing film or peels off the sealing film from the test tube 222.

[0078] In some embodiments, the clamping assembly 250 further includes a first gear 253 and a second gear 254. One end of the first clamping member 251 has a first clamping portion 2511, and the other end of the first clamping member 251 is driveably connected to the first gear 253. One end of the second clamping member 252 has a second clamping portion 2521, and the other end of the second clamping member 252 is driveably connected to the second gear 254. The first clamping portion 2511 and the second clamping portion 2521 are disposed opposite to each other to jointly clamp the test tube 222. The first gear 253 and the second gear 254 mesh to jointly drive the first clamping portion 2511 and the second clamping portion 2521 to move closer or further apart. It is understood that the clamping assembly 250 also includes at least one motor, and at least one of the first gear 253 and the second gear 254 is connected to the motor to drive the first gear 253 and the second gear 254 to rotate.

[0079] The clamping assembly 250 also includes a support frame 255, which is located below the first clamping member 251 and the second clamping member 252. The support frame 255 is connected to the first gear 253 and the second gear 254 to support the first gear 253 and the second gear 254. At the same time, the support frame 255 can raise the height of the first clamping member 251 and the second clamping member 252 so that the first clamping member 251 and the second clamping member 252 are located above the test tube clamp 220.

[0080] Reference Figure 2 , Figure 5 and Figure 7In some embodiments, the sealing film processing mechanism 300 includes: a driving assembly 310, a heating element 320, and a shaping block 330. The shaping block 330 is located around the heating element 320, and the driving assembly 310 is connected to the shaping block 330. The driving assembly 310 drives the heating element 320 to move by driving the shaping block 330, so that the heating element 320 conveys the sealing film on the temporary storage stage 160 to the test tube 222 and contacts the sealing film on the test tube 222. The heating element 320 is used to melt the solid adhesive on the sealing film so that the sealing film is fixed to the test tube 222. The shaping block 330 moves relative to the heating element 320 so that the sealing film around the heating element 320 is fixed to the test tube 222.

[0081] The heating element 320 is a copper block, containing a heating rod and a heating sensor. The heating rod heats the copper block, and the heating sensor controls the heating temperature of the heating rod. The heating element 320 melts the solid adhesive on the sealing film through heating, facilitating adhesion or detachment between the sealing film and the test tube 222. The bottom surface of the heating element 320 contacts the test tube 222, and the bottom surface of the heating element 320 has a circular outline. A shaping block 330 is connected to the periphery of the heating element 320 to match the outline of the bottom surface of the heating element 320 with the outline of the opening of the test tube 222, allowing the sealing film on the heating element 320 to fit tightly against the opening of the test tube 222.

[0082] For example, the drive assembly 310 includes a lead screw motor 311, a lead screw module 312, a first connecting plate 313, and a second connecting plate 314. The first connecting plate 313 is located between the lead screw motor 311 and the lead screw module 312, and the lead screw motor 311 and the lead screw module 312 are connected through the first connecting plate 313. The second connecting plate 314 is located between the lead screw motor 311 and the shaping block 330, and the lead screw motor 311 and the shaping block 330 are connected through the second connecting plate 314. The lead screw motor 311 is used to drive the shaping block 330 to move up and down, and the lead screw module 312 drives the shaping block 330 to move horizontally by driving the lead screw motor 311. The lead screw motor 311 and the lead screw module 312 jointly drive the shaping block 330, so that the shaping block 330 can move in multiple directions.

[0083] In some embodiments, the drive assembly 310 further includes a linear bearing and a guide bearing connected to the linear bearing. Both the linear bearing and the guide bearing are located above the heating element 320. The linear bearing is connected to the second connecting plate 314, and the guide bearing is connected to the linear bearing, providing guidance for the drive assembly 310 through the linear bearing and the guide bearing.

[0084] In a specific implementation, when the test tube 222 below the sealing film processing mechanism 300 is not covered by the sealing film, the driving component 310 drives the shaping block 330 and the heating element 320 to move above the temporary storage stage 160. The heating element 320 moves down to contact the sealing film on the temporary storage stage 160 and transports the sealing film to the test tube 222. At the same time, during the transport of the sealing film, the heating element 320 melts the solid adhesive on the sealing film so that the sealing film can adhere to the test tube 222 when it comes into contact with the test tube 222. The shaping block 330 moves relative to the heating element 320 and extends out of the heating element 320 so that the sealing film around the heating element 320 adheres to the outer wall of the test tube 222, thereby sealing the test tube 222.

[0085] In some embodiments, the temporary storage platform 160 is made of polytetrafluoroethylene to prevent the solid adhesive on the sealing film from adhering to the temporary storage platform 160.

[0086] In some embodiments, the sealing film processing mechanism 300 further includes a vacuum pump, the heating element 320 is hollow, the vacuum pump is connected to the heating element 320, and the vacuum pump is used to create a vacuum in the heating element 320 so that the heating element 320 can pick up the sealing film on the temporary storage stage 160 or pick up the sealing film to be peeled off on the test tube 222.

[0087] When the heating element 320 needs to absorb the sealing film on the test tube 222, the heating element 320 needs to contact the sealing film first and melt the solid adhesive on the sealing film so that the sealing film is separated from the test tube 222.

[0088] In practice, when the sealing film needs to be placed on the test tube 222, and the heating element 320 comes into contact with the sealing film on the temporary storage stage 160, the vacuum pump evacuates the inside of the heating element 320 to create a vacuum inside the heating element 320, so that the heating element 320 can pick up the sealing film on the temporary storage stage 160. When the heating element 320 moves to the test tube 222, the vacuum pump stops evacuating the air, so that the sealing film picked up by the heating element 320 falls onto the test tube 222.

[0089] When it is necessary to peel off the sealing film on the test tube 222, the heating element 320 comes into contact with the sealing film on the test tube 222, and the vacuum pump evacuates the inside of the heating element 320 to create a vacuum inside the heating element 320 so that the heating element 320 can suck up the sealing film on the test tube 222.

[0090] Reference Figure 2 , Figure 5 and Figure 7 In some embodiments, the sealing film processing mechanism 300 further includes a recovery pipe 340 and a peeling plate 350 located above the recovery pipe 340; the recovery pipe 340 is located on one side of the rotating frame 210, the peeling plate 350 is used to peel off the sealing film on the heating element 320 that has moved to the peeling plate 350, and the recovery pipe 340 is used to recover the sealing film peeled off by the peeling plate 350.

[0091] The peeling plate 350 has an arc-shaped groove that corresponds to the recycling pipe 340, so that the sealing film peeled off by the peeling plate 350 can fall into the recycling pipe 340.

[0092] In practice, when the first detection element 230 detects that the test tube 222 is covered with a sealing film, the rotating frame 210 rotates to rotate the test tube 222 to a position below the heating element 320. The heating element 320 contacts the test tube 222 and melts the solid adhesive on the sealing film on the test tube 222, causing the sealing film to detach from the test tube 222. Then, the heating element 320 picks up the sealing film on the test tube 222 and moves to a position above the recovery tube 340. The peeling plate 350 peels off the sealing film on the heating element 320, and the sealing film falls into the recovery tube, thus removing and recovering the sealing film on the test tube 222.

[0093] Reference Figure 3 and Figure 4 In some embodiments, the sealing film delivery mechanism 100 includes a control element 120 and a cutting element 150; the control element 120 controls the placement rack 110 to rotate to deliver the sealing film on the placement rack 110 to the temporary storage table 160, and the cutting element 150 is located between the placement rack 110 and the temporary storage table 160, and the cutting element 150 is used to cut the sealing film.

[0094] The control unit 120 has multiple control knobs to control the rotation or stop the rotation of the placement rack 110. It can be understood that the control unit 120 can also control the forward and reverse rotation of the placement rack 110.

[0095] The cutting component 150 includes a conveying section 151 and a cutting section 152. The conveying section 151 has a groove through which the sealing film is conveyed to the temporary storage table 160. The cutting section 152 is located between the conveying section 151 and the temporary storage table 160. The longitudinal section of the cutting section 152 is trapezoidal, with its acute angle facing the temporary storage table 160. The cutting section 152 moves relative to the conveying section 151 and abuts against the temporary storage table 160 to cut the sealing film, placing the required portion of the sealing film onto the temporary storage table 160. It is understood that the cutting section 152 is close to the temporary storage table 160 to minimize the amount of sealing film on the temporary storage table 160 and avoid waste.

[0096] In some embodiments, a roller 111 is provided on one side of the placement rack 110. The sealing film on the placement rack 110 is conveyed to the cutting member 150 via the roller 111. The roller 111 is used to change the conveying direction of the sealing film and can also press the sealing film to ensure that the sealing film is conveyed flat. The sealing film conveying mechanism 100 also includes a conveying roller 140, which is located between the roller 111 and the cutting member 150. The conveying roller 140 includes two pressure rollers, which abut against both sides of the sealing film to ensure that the sealing film is conveyed flat to the cutting member 150 and to prevent the sealing film from curling during the conveying process.

[0097] In a specific implementation, when the control unit 120 controls the placement rack 110 to rotate, the sealing film on the placement rack 110 begins to be conveyed. The sealing film on the placement rack 110 is conveyed sequentially through the roller 111, the conveying roller 140, and the cutting member 150 to the temporary storage table 160. The cutting member 150 cuts the sealing film so that the required portion of the sealing film is placed on the temporary storage table 160.

[0098] In some embodiments, support members are provided below the conveyor roller 140, the cutter 150, and the temporary storage platform 160, respectively, so that the sealing film on the conveyor roller 140, the cutter 150, and the temporary storage platform 160 is in a horizontal state.

[0099] Reference Figure 3 In some embodiments, the sealing film delivery mechanism 100 further includes a third detection element 130, which is used to detect whether there is a sealing film on the placement rack 110.

[0100] The third detection element 130 is located on one side of the placement rack 110. The third detection element 130 corresponds to the sealing film on the placement rack 110 to detect whether there is a sealing film on the placement rack 110, so that the sealing film on the placement rack 110 can be replenished in time when it is used up.

[0101] For example, the third detection element 130 is a laser detector.
