[0002] Freeze-dried bulbs are small, solid spheres formed by rapidly freezing liquid nitrogen at extremely low temperatures using a specialized precision micro-pump. They are primarily used in medical diagnostics and skincare. During the production of freeze-dried bulbs, after forming, they need to be quickly dispensed into sealed containers or onto reaction discs for subsequent biochemical reactions or testing.

The loading and unloading lines are connected, and the first conveyor line furthest from the loading and unloading mechanisms is connected to the second conveyor line, forming a continuous conveyor line. The loading and unloading mechanism places empty reaction trays onto the carriers of the loading line via a transfer device. The loading line then transports the carriers carrying the reaction trays to the first conveyor line. The carriers carrying the reaction trays are transferred to the unloading line via the first and second conveyor lines. During this process, the freeze-dried pellet packaging modules at the pellet-planting stations of the first and second conveyor lines plant pellets onto the corresponding reaction trays. When the carrier carrying the reaction trays moves to the unloading line, the pellet loading is completed. Then, a transfer device removes the fully loaded reaction trays from the carrier on the unloading line and transfers them to a designated location (such as a pallet or the next processing step), thus completing the automatic dispensing of freeze-dried pellets. The entire process requires no manual operation and has high efficiency. Furthermore, the freeze-dried pellet dispensing process avoids contamination as there is no human contact with the reaction trays or freeze-dried pellets. Attached Figure Description

[0114] Example 1

[0115] like Figures 1 to 10 As shown, this embodiment provides an automatic freeze-dried pellet packaging system, which can achieve automated packaging of freeze-dried pellets with high packaging efficiency. The automatic freeze-dried pellet packaging system includes a loading and unloading mechanism 1 and at least one pellet-planting mechanism 2.

[0116] Among them, see Figure 2 and Figure 3 The loading and unloading mechanism 1 includes a transfer device 11 and a loading line 12 and an unloading line 13 arranged at intervals. Both the loading line 12 and the unloading line 13 are used to transport the carriers 10 that carry the reaction trays. The transfer device 11 is used to pick up and place reaction trays on the carriers 10. That is, the transfer device 11 can place empty reaction trays on the carriers 10 of the loading line 12, and the transfer device 11 can remove full-load reaction trays from the carriers 10 of the unloading line 13, realizing automatic loading and unloading of reaction trays. Here, a full-load reaction tray refers to a reaction tray that has been transferred to the unloading line 13 after the ball-planting operation is completed. A full-load reaction tray includes reaction trays with ball-planting that meets the requirements, as well as reaction trays with unqualified ball-planting.

[0117] See Figure 1 , Figure 2 , Figure 4 , Figure 9 and Figure 10 At least one ball-planting mechanism 2 is sequentially arranged along the conveying direction of the carrier 10. The ball-planting mechanism 2 includes a first conveyor line 22 and a second conveyor line 23 arranged at intervals. Both the first conveyor line 22 and the second conveyor line 23 are used to convey the carrier 10 that carries the reaction disc. The first conveyor line 22 is located on one side of the loading line 12, and the second conveyor line 23 is located on one side of the unloading line 13. In this embodiment, the first conveyor line 22 and the loading line 12 are on the same transmission line, and the second conveyor line 23 and the unloading line 13 are on the same transmission line. The loading line 12 and the unloading line 13 are connected. The first conveyor line 22, which is furthest from the loading and unloading mechanism 1, is connected to the second conveyor line 23, forming a circular conveyor line.

[0118] See Figure 9 , Figure 10 , Figure 11 and Figure 12 The ball-planting mechanism 2 also includes a freeze-dried ball dispensing module 21. The first conveyor line 22 and the second conveyor line 23 each have at least one ball-planting station 24. At least one freeze-dried ball dispensing module 21 is provided at each ball-planting station 24. The freeze-dried ball dispensing module 21 is used to plant balls onto the reaction trays on the corresponding first conveyor line 22 and / or second conveyor line 23.

[0119] The automatic freeze-dried pellet packaging system provided in this embodiment uses a loading and unloading mechanism 1 to load and unload the reaction tray, and a pellet-planting mechanism 2 to plant pellets onto the reaction tray. Together, they achieve automatic packaging of freeze-dried pellets onto the reaction tray, improving packaging efficiency. Specifically, several first conveyor lines 22 of the pellet-planting mechanisms 2 are on the same conveyor line as the loading line 12, and several second conveyor lines 23 of the pellet-planting mechanisms 2 are on the same conveyor line as the unloading line 13. The loading line 12 and the unloading line 13 are connected, and the first conveyor line 22 furthest from the loading and unloading mechanism 1 is connected to the second conveyor line 23, forming a continuous conveyor line. The loading and unloading mechanism 1 places empty reaction trays onto the carrier 10 of the loading line 12 via the transfer device 11. The loading line 12 then transports the carrier 10 carrying the reaction trays to the first conveyor line 22. The carrier 10 then flows through the first conveyor line 22 and the second conveyor line 23 to the unloading line 13. During this process, the freeze-dried ball dispensing module 21 at the ball-planting station 24 of the first and second conveyor lines 22 and 23 plants balls onto the corresponding reaction trays. When the carrier 10 carrying the reaction trays flows to the unloading line 13, the ball planting is complete. The transfer device 11 then removes the fully loaded reaction trays from the carrier 10 of the unloading line 13 and transfers them to a designated location (e.g., a pallet or the next processing step), thus completing the automatic dispensing of freeze-dried balls. The entire process requires no manual operation, resulting in high efficiency. Furthermore, the freeze-dried ball dispensing process avoids human contact with the reaction trays or freeze-dried balls, preventing contamination.

[0120] For example, see Figure 1 and Figure 2 The ball-planting mechanism 2 has four units. Each ball-planting mechanism 2 has two ball-planting stations 24 on its first conveyor line 22 and second conveyor line 23. Each ball-planting station 24 is equipped with four freeze-dried ball packaging modules 21, such as... Figure 9 and Figure 11 As shown, the four freeze-dried pellet dispensing modules 21 can output freeze-dried pellets of the same or different types to meet the pellet loading requirements of different reaction discs and improve the adaptability of the automatic freeze-dried pellet dispensing system.

[0121] In other embodiments, the number of ball-planting mechanisms 2 can be increased or decreased as needed. For example, one, two, three, five, or other ball-planting mechanisms 2 can be set. The number of ball-planting stations 24 and freeze-dried ball packaging modules 21 on each ball-planting mechanism 2 can also be increased or decreased, and are not limited to the numbers and distribution methods listed above.

[0122] Optionally, see Figure 1 and Figure 2The loading and unloading mechanism 1 is equipped with a first protective cover 19, which covers the loading line 12 and the unloading line 13. The first protective cover 19 ensures that the loading and unloading of the reaction tray are in a relatively enclosed space, ensuring that the entire flow process of the reaction tray is in a relatively clean space and preventing contamination of the freeze-dried balls.

[0123] See Figure 1 and Figure 2 The pelleting mechanism 2 is equipped with a second protective cover 26, which covers the first conveyor line 22 and the second conveyor line 23. The second protective cover 26 ensures that the reaction tray remains in a relatively enclosed space during the pelleting process, preventing contamination of the freeze-dried pellets on the reaction tray.

[0124] Optionally, see Figure 2 , Figure 3 and Figure 5 A feeding station 14 is provided on one side of the feeding line 12. A first tray 141 for holding empty reaction trays is stacked at the feeding station 14. The transfer device 11 includes a first clamping component 111, which is used to clamp the empty reaction trays from the first tray 141 and place the empty reaction trays on the carrier 10 of the feeding line 12 to realize the automatic feeding of empty reaction trays.

[0125] Specifically, see Figure 7 The first clamping assembly 111 includes a clamping drive 1111 and two clamping claws 1112. The clamping drive 1111 can drive the two clamping claws 1112 to clamp or release the reaction disk 20, and the clamping drive 1111 can drive the two clamping claws 1112 to rotate to adjust the position of the reaction disk 20 so that the reaction disk 20 is aligned with the carrier 10 and the reaction disk 20 is placed at the designated position of the carrier 10.

[0126] For example, the clamping drive 1111 may include a rotary drive and a linear drive. The linear drive is disposed at the output end of the rotary drive and is used to drive the two clamping jaws 1112 to move towards or away from each other to clamp or release the reaction disk 20. The rotary drive is used to drive the linear drive to rotate the reaction disk 20, thereby adjusting the position of the reaction disk 20.

[0127] See Figure 8 The transfer device 11 also includes a three-axis module 113, which includes an X-axis module 1131, a Y-axis module 1132, and a Z-axis module 1133. The three are perpendicular to each other. The Y-axis module 1132 extends along the conveying direction of the feeding line 12. The first clamping component 111 is mounted on the Z-axis module 1133. The position of the first clamping component 111 in the X, Y, and Z directions can be adjusted by the three-axis module 113, so that the first clamping component 111 can flexibly pick up and put down the reaction tray.

[0128] Furthermore, the loading station 14 has a first area and a second area. The first area is used to stack first trays 141 containing empty reaction discs, and the second area is used to stack empty first trays 141. Multiple empty reaction discs can be placed in the first tray 141. The first clamping component 111 clamps the empty reaction discs from the first tray 141 in the first area. After all the empty reaction discs in the first tray 141 are removed, the empty first tray 141 is transferred to the second area for stacking. The layout is reasonable, which can ensure the continuity of the reaction disc loading operation and improve the loading efficiency.

[0129] Optionally, see Figure 2 , Figure 3 and Figure 5 A feeding station 15 is provided on one side of the feeding line 13. A second tray 151 for holding a full-load reaction disk is stacked at the feeding station 15. The transfer device 11 includes a second clamping assembly 112, which is used to clamp the full-load reaction disk from the carrier 10 of the feeding line 13 and place the full-load reaction disk into the second tray 151, thereby realizing automatic feeding of the full-load reaction disk. In this embodiment, the second clamping assembly 112 has the same structure as the first clamping assembly 111, including a clamping drive 1111 and two clamping claws 1112. The clamping drive 1111 can drive the two clamping claws 1112 to clamp or release the full-load reaction disk, so as to remove the full-load reaction disk from the carrier 10 and transfer it to a designated position.

[0130] Of course, in other embodiments, the structure of the second clamping component 112 may also be different from that of the first clamping component 111, as long as it can automatically clamp and release the reaction disk.

[0131] See Figure 5 and Figure 8 The transfer device 11 has two Z-axis modules 1133. The first clamping component 111 and the second clamping component 112 are respectively installed on the two Z-axis modules 1133, so that the first clamping component 111 and the second clamping component 112 can flexibly pick up and put down the reaction disk.

[0132] See Figure 3 and Figure 5 The unloading station 15 has a third area and a fourth area. The third area is used to stack second pallets 151 filled with full reaction trays, and the fourth area is used to stack empty second pallets 151. Multiple full reaction trays can be placed in the second pallet 151. After the second clamping assembly 112 clamps the full reaction tray from the carrier 10 of the unloading line 13, it places it on the second pallet 151 in the third area. After the second pallet 151 is filled with full reaction trays, the empty second pallets 151 in the fourth area are transferred to the third area for stacking. The layout is reasonable and can ensure the continuity of the reaction tray unloading operation and improve the unloading efficiency.

[0133] Optionally, see Figure 3 and Figure 5 The loading and unloading mechanism 1 also includes a first vision detection device 16. The first clamping assembly 111 places the gripped empty reaction disk onto the carrier 10 of the loading line 12 based on the information detected by the first vision detection device 16, ensuring the reaction disk is correctly positioned on the carrier 10. Specifically, the first vision detection device 16 can take pictures of the carrier 10 to obtain positioning information. The first clamping assembly 111 controls the clamping claw 1112 to rotate the reaction disk at a certain angle based on the positioning information, placing the reaction disk at the designated position on the carrier 10. This ensures the reaction disk can stably flow on the first conveyor line 22 and the second conveyor line 23, and that the subsequent ball-planting process can proceed normally. For example, the first vision detection device 16 is a vision camera.

[0134] See Figure 6 The feeding line 12 is equipped with an antistatic device 121. This device removes static electricity from the reaction plates on the feeding line 12, preventing static electricity from affecting ball placement and ensuring smooth subsequent ball placement processes. For example, the antistatic device 121 can be an ion air knife, which blows ion air onto the reaction plates, causing positive and negative ions to interact with the static charge on the surface of the object, neutralizing or separating the static charge, thereby eliminating static electricity. In other embodiments, the antistatic device 121 can also be an ion fan, ion gun, etc.

[0135] Optionally, see Figure 3 and Figure 5 A non-conforming product buffer station 18 is provided on one side of the unloading line 13. The loading and unloading mechanism 1 also includes a second vision inspection device 17, which is used to detect whether the full-load reaction trays on the unloading line 13 are qualified. The second clamping assembly 112 can place the qualified full-load reaction trays on the second tray 151, and the second clamping assembly 112 can place the unqualified full-load reaction trays on the non-conforming product buffer station 18. The second vision inspection device 17 can promptly sort out unqualified products, prevent unqualified products from flowing into the next production process, and improve the overall product qualification rate.

[0136] Specifically, the second visual inspection device 17 can take pictures of the fully loaded reaction tray on the carrier 10 to obtain image information of the fully loaded reaction tray. Based on the image information, it analyzes whether the quality of the freeze-dried balls on the reaction tray meets the requirements, so as to determine whether the fully loaded reaction tray after ball loading is qualified. The items analyzed may include, but are not limited to, pits on the freeze-dried balls (for example, pits deeper than 0.5 mm are unqualified), burrs, peeling, cracks, and the number of freeze-dried balls on the reaction tray. For example, the second visual inspection device 17 is a visual camera.

[0137] See Figure 3 and Figure 13 A buffer device 181 is provided at the non-conforming product buffer station 18. The second clamping component 112 places the non-conforming, fully loaded reaction disks on the buffer device 181 for easy subsequent recycling. For example, the buffer device 181 includes a support platform and a limiting post disposed on the support platform. The non-conforming reaction disks pass through the limiting post, and multiple non-conforming reaction disks are stacked.

[0138] Optionally, see Figure 1 and Figure 2 A first transfer line 3 is provided between the feeding line 12 and the unloading line 13. The first transfer line 3 is used to transport the empty carriers 10 on the unloading line 13 to the feeding line 12. That is, the feeding line 12 is connected to the unloading line 13 through the first transfer line 3, so that the empty carriers 10 on the unloading line 13 can be transferred to the feeding line 12 via the first transfer line 3, realizing the recycling of the carriers 10, which can further improve the feeding efficiency and thus improve the freeze-dried pellet packaging efficiency.

[0139] See Figure 1 , Figure 2 and Figure 4 A second transfer line 4 is provided between the first conveyor line 22 and the second conveyor line 23 of the ball-planting mechanism 2, which is furthest from the loading and unloading mechanism 1. The second transfer line 4 is used to transport the carrier 10 on the first conveyor line 22 to the second conveyor line 23. That is, the first conveyor lines 22 and the second conveyor lines 23 of several ball-planting mechanisms 2 are connected by the second transfer line 4, so that the loading line 12, several first conveyor lines 22, several second conveyor lines 23 and unloading line 13 form a closed-loop conveyor line, so that the carrier 10 can carry the reaction plate to perform the same or different types of freeze-dried balls at different ball-planting stations 24.

[0140] See Figure 1 , Figure 3 and Figure 5 A third transfer line 5 is provided between the loading / unloading mechanism 1 and its adjacent ball-planting mechanism 2. The third transfer line 5 is used to transport the carrier 10 on the loading line 12 to the first conveyor line 22, and to transport the carrier 10 on the second conveyor line 23 to the unloading line 13. That is, the carrier 10 is transferred between the loading / unloading mechanism 1 and the ball-planting mechanism 2 via the third transfer line 5, ensuring that the carrier 10 on the loading line 12 can be smoothly transferred to the first conveyor line 22, and ensuring that the carrier 10 on the second conveyor line 23 can be smoothly transferred to the unloading line 13.

[0141] In this embodiment, the first transfer line 3, the second transfer line 4, and the third transfer line 5 have the same structure. (See reference...) Figure 14Taking the third transfer line 5 as an example, the third transfer line 5 includes a guide rail and a carrying platform that is slidably set on the guide rail. The guide rail extends along the conveying direction of the carrier 10. A conveyor belt is set on the carrying platform. The feeding line 12 conveys the carrier 10 to the conveyor belt of the carrying platform. The carrying platform drives the carrier 10 to slide along the guide rail to the first conveyor line 22. The conveyor belt then conveys the carrier 10 to the first conveyor line 22.

[0142] In other embodiments, the third transfer line 5 may be omitted, and the loading line 12 may be directly connected to the first conveying line 22, and the unloading line 13 may be directly connected to the second conveying line 23.

[0143] Optionally, see Figure 1 , Figure 2 and Figure 4 At least one pellet loading mechanism 2 is equipped with a reagent loading station 25, and a reagent loading device 6 is provided at the reagent loading station 25. The reagent loading device 6 is used to load the reagent package for the lyophilized pellet reaction test onto the reaction plate, realizing automatic loading of the reagent package. In this embodiment, the center of the reaction plate has a groove for holding the reagent package. The reagent loading device 6 places the reagent package in the groove. For example, one reagent package is placed on each reaction plate. When performing the lyophilized pellet reaction test, the reagent package only needs to be punctured to fuse the reagent with the lyophilized pellet, and the reaction test data of the lyophilized pellet can be detected by the detection instrument.

[0144] This embodiment is described in the reference section. Figure 1 and Figure 2 The reagent feeding device 6 is located at the far left of the whole machine, that is, in the corner of the whole machine. This can avoid the reagent feeding device 6 occupying the manual passage on both sides of the whole machine. The spatial layout is reasonable and can save factory space to the maximum extent.

[0145] See Figure 10 The reagent feeding device 6 includes a vibratory feeder 61 and a reagent pack picking device 62. The reagent pack picking device 62 is located above the second conveyor line 23 of the last ball-planting mechanism 2. The vibratory feeder 61 is used to transfer the reagent pack to the reagent pack picking device 62. The reagent pack picking device 62 picks up the reagent pack and places it on the reaction plate of the second conveyor line 23.

[0146] Optionally, see Figure 11 , Figure 12 , Figure 15 and Figure 16The freeze-dried pellet dispensing module 21 includes a freeze-dried pellet dispensing device 211, which includes a storage bin 2111, a base 2112, and a first detection device 2114. The storage bin 2111 holds the freeze-dried pellets. The base 2112 is located below the storage bin 2111, and the base 2112 has a dispensing channel 21121 communicating with the storage bin 2111. The dispensing channel 21121 has a blocking space 21122 that blocks individual freeze-dried pellets, and the dispensing channel 21121 selectively opens or closes at the blocking space 21122. The first detection device 2114 detects whether there are freeze-dried pellets in the blocking space 21122. When there are freeze-dried pellets in the blocking space 21122, the dispensing channel 21121 is open.

[0147] Specifically, when the freeze-dried balls in the storage bin 2111 enter the dispensing channel 21121 and reach the blocking space 21122, the first detection device 2114 detects the presence of freeze-dried balls in the blocking space 21122. At this point, the dispensing channel 21121 is opened, and the freeze-dried balls in the blocking space 21122 automatically enter the equipment for the next processing step or fall into the container 30 containing the freeze-dried balls, thus achieving the dispensing of freeze-dried balls. Since the blocking space 21122 can only hold a single freeze-dried ball, only one freeze-dried ball can fall into the equipment for the next process or into the container 30 at a time, achieving accurate control of the dispensing quantity of freeze-dried balls. The first detection device 2114 controls the opening and closing of the dispensing channel 21121 based on the presence or absence of freeze-dried balls in the blocking space 21122, achieving fully automatic dispensing of freeze-dried balls and ensuring dispensing accuracy. Furthermore, during the material distribution process, the freeze-dried pellets are always kept in the closed environment of the storage bin 2111 and the distribution channel 21121, which can isolate them from the external environment, prevent cross-contamination caused by contact between the freeze-dried pellets and foreign objects, and ensure the packaging quality of the freeze-dried pellets.

[0148] In this embodiment, the lateral space of the dispensing channel 21121 allows only a single freeze-dried ball to pass through. The width of the dispensing channel 21121 is defined as D, and the diameter of the freeze-dried ball is defined as d, where d < D < 2d, to ensure that the lateral space of the dispensing channel 21121 allows only a single freeze-dried ball to pass through, and to ensure that the freeze-dried ball moves smoothly within the dispensing channel 21121. For example, the width of the dispensing channel 21121 is 0.2 mm larger than the diameter of the freeze-dried ball.

[0149] See Figure 12The freeze-dried pellet dispensing device 211 also includes a first blocking member 2113 movably disposed on the base 2112. The first blocking member 2113 has a first position and a second position. In the first position, the first blocking member 2113 extends into the dispensing channel 21121 and forms a blocking space 21122 within the dispensing channel 21121. In the second position, the first blocking member 2113 moves out of the dispensing channel 21121 to open the dispensing channel 21121, allowing the freeze-dried pellets to flow out of the dispensing channel 21121, thereby achieving selective opening or closing of the dispensing channel 21121.

[0150] Furthermore, the first blocking member 2113 can be controlled to move linearly by a linear drive component such as a cylinder, so as to extend into or out of the material distribution channel 21121, thereby realizing automatic control of the opening and closing of the material distribution channel 21121.

[0151] Optionally, the first detection device 2114 includes an optical fiber detection element, that is, it determines whether there are freeze-dried balls in the blocking space 21122 by means of optical fiber detection, which has high detection efficiency and accuracy. For example, the optical fiber detection element is an optical fiber sensor. In other embodiments, the first detection device 2114 may also be an infrared sensor, etc., to detect whether there are freeze-dried balls in the blocking space 21122.

[0152] Optionally, see Figure 12 and Figure 15 The material distribution channel 21121 includes a first channel 21121a, a second channel 21121b, and a third channel 21121c connected in sequence. The first channel 21121a is connected to the storage bin 2111. The second channel 21121b is inclined relative to the horizontal plane and has a slope towards the first channel 21121a. In the first position, the first blocking member 2113 extends into the third channel 21121c and forms a blocking space 21122 at the connection between the third channel 21121c and the second channel 21121b. That is, the blocking space 21122 is located at the higher end of the second channel 21121b, and the freeze-dried balls in the storage bin 2111 enter from the first channel 21121a and are located at the lower end of the second channel 21121b. Since the blocking space 21122 can only hold one freeze-dried ball, and the second channel 21121b has a slope, only one freeze-dried ball can be temporarily stored in the blocking space 21122 at a time. The remaining freeze-dried balls can only stay in the first channel 21121a and the connection between the first channel 21121a and the second channel 21121b. In this way, after the first blocking member 2113 switches to the second position, it can be further ensured that only one freeze-dried ball can be output from the third channel 21121c, so as to accurately control the number of freeze-dried balls distributed.

[0153] In this embodiment, the second channel 21121b is arranged horizontally at an angle, while the first channel 21121a and the third channel 21121c are both arranged vertically. With this arrangement, the freeze-dried pellets can fall smoothly from the storage bin 2111 into the first channel 21121a under their own gravity, and the freeze-dried pellets in the blocking space 21122 can also fall smoothly into the third channel 21121c under their own gravity, thus improving the material distribution efficiency.

[0154] Furthermore, the inner walls of the second channel 21121b and the third channel 21121c are connected in an arc-shaped transition to form an arc-shaped blocking surface 21121d (e.g., Figure 15 As shown, an arc-shaped blocking surface 21121d and the first blocking member 2113 enclose a blocking space 21122. When the first blocking member 2113 is in the first position, the arc-shaped blocking surface 21121d is located above the first blocking member 2113. The arc-shaped blocking surface 21121d makes the shape of the blocking space 21122 more suitable for the spherical freeze-dried ball, preventing the freeze-dried ball from getting stuck in the blocking space 21122. After the first blocking member 2113 switches to the second position, it ensures that the freeze-dried ball can fall smoothly into the third channel 21121c. At the same time, the arc-shaped blocking surface 21121d can prevent scratching the freeze-dried ball and avoid damage to it. The curvature of the arc-shaped blocking surface 21121d can be adaptively designed according to the diameter of the freeze-dried ball, as long as it ensures that only a single freeze-dried ball can exist in the blocking space 21122.

[0155] Optionally, the freeze-dried pellet dispensing device 211 further includes a first air-blowing device 21123 disposed on the base 2112. The air outlet of the first air-blowing device 21123 is used to blow air towards the lower end of the second channel 21121b, so that the freeze-dried pellets move along the second channel 21121b into the blocking space 21122. Driving the freeze-dried pellets by blowing air prevents foreign objects from directly contacting the freeze-dried pellets, further preventing contamination. At the same time, the airflow driving method is relatively gentle, which can prevent the freeze-dried pellets from breaking or shedding powder, ensuring the quality of the freeze-dried pellets. For example, the first air-blowing device 21123 can be an air pump, etc.

[0156] See Figure 12 and Figure 15 The base 2112 is provided with an exhaust channel 21125. One end of the exhaust channel 21125 is connected to the blocking space 21122, and the other end of the exhaust channel 21125 is connected to the external space. The airflow reaching the blocking space 21122 can be discharged to the outside through the exhaust channel 21125, thereby preventing the airflow backflow from causing the freeze-dried bulb to roll back into the second channel 21121b, and ensuring that the freeze-dried bulb can be stably stored in the blocking space 21122.

[0157] Optionally, a limiting groove 21131 is provided at one end of the first blocking member 2113 that extends into the material distribution channel 21121 (e.g., Figure 15 As shown), in the first position, the freeze-dried ball in the blocking space 21122 is confined within the limiting groove 21131, allowing the freeze-dried ball to be stably and temporarily stored within the blocking space 21122. In this embodiment, after the freeze-dried ball reaches the blocking space 21122, a portion of it is located within the limiting groove 21131, and the center of gravity of the freeze-dried ball falls within the limiting groove 21131. That is, the center of gravity of the freeze-dried ball is within the third channel 21121c (i.e., the center of gravity of the freeze-dried ball is deviated from the second channel 21121b). As the first blocking member 2113 moves from the first position to the second position, the freeze-dried ball can fall rapidly under its own gravity, effectively improving the falling efficiency of the freeze-dried ball, while ensuring that the freeze-dried ball does not fall back into the second channel 21121b.

[0158] In this embodiment, the wall of the limiting groove 21131 is an arc-shaped surface to adapt to the shape of the freeze-dried balls, so that the freeze-dried balls can be more stably stored in the limiting groove 21131. At the same time, the arc-shaped surface can prevent scratching the freeze-dried balls and ensure the quality of the freeze-dried balls after they are separated.

[0159] Optionally, the freeze-dried pellet dispensing equipment 211 further includes a second air blowing device 2116 (e.g., air blowing device 2116) disposed in the storage silo 2111. Figure 17 As shown, the outlet of the second air blowing device 2116 is used to blow air into the storage bin 2111 to move the freeze-dried balls inside the storage bin 2111, preventing the freeze-dried balls from agglomerating and adsorbing together due to electrostatic discharge, and ensuring that the freeze-dried balls can fall smoothly into the distribution channel 21121. For example, the second air blowing device 2116 can be an air pump or the like.

[0160] The inner cavity of the storage bin 2111 includes a first cavity and a second cavity that are connected to each other. The second cavity is closer to the base 2112, and the cross-sectional area of ​​the second cavity gradually decreases towards the base 2112 to form an inclined guide wall within the second cavity. That is, the second cavity is funnel-shaped, allowing the freeze-dried pellets to automatically collect downwards under their own gravity and fall into the distribution channel 21121, thereby improving the pellet dropping efficiency.

[0161] Furthermore, the storage bin 2111 is provided with an inclined air intake channel 21111 (e.g., Figure 17 As shown, the outlet of the air inlet channel 21111 is located at the bottom of the second cavity, allowing airflow to enter from the bottom of the inner cavity of the storage bin 2111. This prevents the freeze-dried pellets from accumulating at the outlet of the storage bin 2111, ensuring normal pellet drop. Furthermore, the inclination angle of the air inlet channel 21111 is the same as or approximately the same as the inclination angle of the guide wall, allowing the airflow to act on more freeze-dried pellets, thereby quickly breaking up the accumulation of freeze-dried pellets and ensuring normal pellet drop. Here, "approximately the same" means that the air inlet channel 21111 and the guide wall are roughly parallel, for example, the difference in their inclination angles can be within 5°.

[0162] See Figure 12 and Figure 15 The freeze-dried pellet dispensing equipment 211 also includes a third detection device 2115. This third detection device 2115 detects the remaining amount of freeze-dried pellets in the storage hopper 2111. When the third detection device 2115 detects that the remaining amount of freeze-dried pellets in the storage hopper 2111 is lower than a set threshold, the freeze-dried pellet dispensing equipment 211 issues a warning signal, facilitating timely replenishment of the storage hopper 2111. This ensures the continuous operation of the freeze-dried pellet dispensing equipment 211 and improves dispensing efficiency. Replenishment can be done manually or automatically by the machine.

[0163] For example, the third detection device 2115 includes an optical fiber detection element, that is, it determines the remaining amount of freeze-dried balls in the storage bin 2111 by means of optical fiber detection.

[0164] Optionally, see Figure 11 and Figure 12 The freeze-dried pellet dispensing module 21 includes a freeze-dried pellet dispensing device 212 disposed below the freeze-dried pellet dispensing device 211. The freeze-dried pellet dispensing device 212 includes a main body 2121, a second detection device, and a feeding device. The main body 2121 is provided with a buffer channel 21211, a qualified channel 21212, and a non-qualified channel 21213. One end of the buffer channel 21211 is connected to the dispensing channel 21121, and the other end of the buffer channel 21211 can selectively connect to the qualified channel 21212 or the non-qualified channel 21213. The second detection device is used to detect the number of freeze-dried pellets in the buffer channel 21211. When the number of freeze-dried pellets in the buffer channel 21211 is 1, the buffer channel 21211 is connected to the qualified channel 21212. A feeding device is installed in the main body of the equipment 2121. When the number of freeze-dried balls in the buffer channel 21211 is greater than 1, the buffer channel 21211 is connected to the unqualified channel 21213, and the feeding device sends at least a portion of the freeze-dried balls in the buffer channel 21211 into the unqualified channel 21213. That is, the freeze-dried ball dispensing equipment 212 can further screen the freeze-dried balls output from the dispensing channel 21121 to ensure that only one freeze-dried ball enters the container 30 storing freeze-dried balls from the qualified channel 21212 at a time, thereby accurately controlling the number of freeze-dried balls entering the container 30 at a time to be 1, and ensuring the accuracy of the freeze-dried ball dispensing dosage.

[0165] See Figure 12 , Figure 18 and Figure 19The freeze-dried pellet dispensing equipment 212 also includes a second blocking member 2124 and a third blocking member 2125 movably disposed on the equipment body 2121. The second blocking member 2124 can extend into the qualified channel 21212 to separate the qualified channel 21212 from the buffer channel 21211; the third blocking member 2125 can extend into the unqualified channel 21213 to separate the unqualified channel 21213 from the buffer channel 21211. By controlling the movement of the second blocking member 2124 and the third blocking member 2125, the buffer channel 21211 can be selectively connected to the qualified channel 21212 or the unqualified channel 21213.

[0166] Specifically, in the initial state, neither the qualified channel 21212 nor the unqualified channel 21213 is connected to the buffer channel 21211, and the lower end of the buffer channel 21211 is closed. The freeze-dried balls entering the buffer channel 21211 are temporarily stored in the buffer channel 21211. If it is detected that the number of freeze-dried balls in the buffer channel 21211 is 1, the second blocking member 2124 can be controlled to move out of the qualified channel 21212 to connect the qualified channel 21212 and the buffer channel 21211, so that the freeze-dried balls in the buffer channel 21211 flow out through the qualified channel 21212 to the container 30 storing the freeze-dried balls, completing one batch of freeze-dried balls.

[0167] If the number of freeze-dried balls detected in the buffer channel 21211 is greater than 1, the third blocking member 2125 is controlled to move out of the unqualified channel 21213 (at this time, the second blocking member 2124 remains in the state of extending into the qualified channel 21212, ensuring that the qualified channel 21212 and the buffer channel 21211 are not connected), so as to connect the unqualified channel 21213 and the buffer channel 21211, and control the pusher to send some or all of the freeze-dried balls in the buffer channel 21211 into the unqualified channel 21213. Only when the number of freeze-dried balls detected is 1 can the buffer channel 21211 be connected to the qualified channel 21212, ensuring that only one freeze-dried ball can enter the container 30 through the qualified channel 21212 at a time.

[0168] Optionally, the second blocking member 2124 and the third blocking member 2125 can be controlled to move linearly by a linear drive component such as a cylinder, so as to realize the automatic control of the opening and closing of the buffer channel 21211 with the qualified channel 21212 and the unqualified channel 21213.

[0169] Optionally, the cache channel 21211 has several freeze-dried ball cache positions arranged sequentially from bottom to top, and each freeze-dried ball cache position can only hold a single freeze-dried ball. That is, multiple freeze-dried balls can only be stacked sequentially from bottom to top within the freeze-dried ball cache channel 21211. See reference. Figure 19The second detection device includes a first detection element 2120a and a second detection element 2120b. The first detection element 2120a and the second detection element 2120b are respectively used to detect whether there are freeze-dried balls in the two adjacent freeze-dried ball buffer positions at the bottom of the buffer channel 21211. Specifically, when both the first detection element 2120a and the second detection element 2120b detect freeze-dried balls, it indicates that the first and second freeze-dried ball buffer positions from the bottom up in the buffer channel 21211 contain freeze-dried balls, that is, there are at least two freeze-dried balls in the buffer channel 21211, and the number of freeze-dried balls is greater than one. At this time, the third blocking element 2125 is controlled to move out of the non-qualified channel 21213 to connect the buffer channel 21211 and the non-qualified channel 21213. Then, the pushing device is controlled to move, sending at least a portion of the freeze-dried balls in the buffer channel 21211 into the non-qualified channel 21213. When the first detector 2120a detects the presence of a freeze-dried ball while the second detector 2120b detects the absence of a freeze-dried ball, it indicates that there is currently only one freeze-dried ball in the buffer channel 21211. At this point, the third blocking element 2125 is controlled to extend into the non-qualified channel 21213, and the second blocking element 2124 is controlled to move out of the qualified channel 21212. The freeze-dried ball can then fall into the qualified channel 21212, completing one batch of freeze-dried balls.

[0170] Optionally, both the first detection element 2120a and the second detection element 2120b include an optical fiber detection element, which can detect whether there are lyophilized balls in the lyophilized ball buffer position. That is, the presence or absence of lyophilized balls in the lyophilized ball buffer position is detected by optical fiber detection, thereby determining whether the number of lyophilized balls in the buffer channel 21211 is 1, which has high detection efficiency and accuracy.

[0171] Optionally, the pushing device includes a third air blowing device 2123 (e.g., Figure 12 As shown, the third air-blowing device 2123 can blow the freeze-dried balls in the buffer channel 21211 into the non-conforming channel 21213, causing the freeze-dried balls to move into the non-conforming channel 21213 under the propulsion of the airflow. This air-blowing method avoids direct contact between foreign objects and the freeze-dried balls, preventing contamination. Simultaneously, the gentle airflow prevents breakage or powder shedding from the freeze-dried balls, ensuring their quality. For example, the third air-blowing device 2123 can be an air pump, etc.

[0172] Further, see Figure 18The main body 2121 of the equipment is provided with an air inlet space 21214. The air outlet of the third air blowing device 2123 is connected to the air inlet space 21214. The air inlet space 21214 has an air blowing port 21214a that extends obliquely toward the non-conforming channel 21213. After the airflow generated by the third air blowing device 2123 enters the air inlet space 21214, it can be blown toward the freeze-dried balls in the buffer channel 21211 through the air blowing port 21214a, so that the freeze-dried balls move into the non-conforming channel 21213 under the propulsion of the airflow. Since the air blowing port 21214a extends obliquely toward the non-conforming channel 21213, the airflow can always flow toward the non-conforming channel 21213, so as to drive the freeze-dried balls smoothly from the buffer channel 21211 into the non-conforming channel 21213, thereby improving the dispensing efficiency of the freeze-dried balls.

[0173] Of course, in other alternative embodiments, the pushing device can also be a push rod movably disposed on the main body 2121 of the equipment, which can push the freeze-dried balls in the buffer channel 21211 to move to the non-qualified channel 21213. Specifically, the push rod can be the push rod of a push rod motor, or the push rod can be the output rod of a cylinder.

[0174] See Figure 9 and Figure 11 The freeze-dried pellet dispensing module 21 also includes a control cabinet 214, which is equipped with electrical components such as control circuit boards and solenoid valves to control the operating status of the freeze-dried pellet dispensing equipment 211 and the freeze-dried pellet dispensing equipment 212, thereby achieving electrified automatic control.

[0175] Optionally, see Figure 20 , Figure 21 and Figure 22 The freeze-dried pellet dispensing module 21 also includes a freeze-dried pellet feeding device 213, which includes a fixed frame 2131 and a feeding bin 2132. The discharge end of the feeding bin 2132 can be connected to the storage bin 2111 of the freeze-dried pellet dispensing device 211. The feeding bin 2132 is swayably mounted on the fixed frame 2131. When the feeding bin 2132 is tilted relative to the fixed frame 2131 at a preset angle, the freeze-dried pellets in the feeding bin 2132 can fall into the storage bin 2111 through the discharge end of the feeding bin 2132. By tilting the feeding bin 2132 at a certain angle, the freeze-dried pellets can automatically enter the storage bin 2111 of the freeze-dried pellet dispensing device 211, realizing automatic feeding of the freeze-dried pellet dispensing device 211 and improving the feeding efficiency of the freeze-dried pellets. Furthermore, the automatic feeding method of tilting the feeding bin 2132 to drop the freeze-dried balls can prevent damage to the freeze-dried balls, ensure the quality of the freeze-dried balls after packaging, and improve the product qualification rate.

[0176] See Figure 20 and Figure 21The freeze-dried pellet feeding device 213 also includes a lifting drive 2133. The feeding bin 2132 includes a first end and a second end arranged opposite to each other. The first end serves as a connecting end, and the second end serves as a free end. For example, the first end is rotatably connected to the fixed frame 2131. The lifting drive 2133 is used to drive the feeding bin 2132 to swing up and down relative to the fixed frame 2131, so that the second end rises relative to the first end. Specifically, when the output end of the lifting drive 2133 rises, it can apply an upward force to the feeding bin 2132. Since the first end of the feeding bin 2132 is rotatably connected to the fixed frame 2131, the second end, which is the free end in the feeding bin 2132, can rise relative to the first end, causing the feeding bin 2132 to tilt relative to the fixed frame 2131, so that the freeze-dried pellets in the feeding bin 2132 can roll into the cutting chamber 21340 under their own gravity. The tilt angle of the feeding hopper 2132 is adjusted by lifting, resulting in a simple and easy-to-implement structure with stable lifting drive. This minimizes the risk of freeze-dried pellet breakage and ensures the quality of the packaged freeze-dried pellets. For example, the lifting drive component 2133 can be a linear drive component such as a cylinder or electric cylinder.

[0177] The aforementioned preset angle can be determined based on the actual amount of freeze-dried pellets replenished. For example, if the amount of freeze-dried pellets replenished is large, the lifting drive 2133 can be raised to a higher height, causing the feeding bin 2132 to tilt at a larger angle; if the amount of freeze-dried pellets replenished is small, the lifting drive 2133 can be raised to a smaller height, causing the feeding bin 2132 to tilt at a smaller angle.

[0178] Optionally, see Figure 21 The output end of the lifting drive component 2133 is provided with a rotatable rolling element 21331. The rolling element 21331 rolls in cooperation with the outer peripheral surface of the feeding bin 2132, which can reduce the driving resistance of the lifting drive component 2133 and improve the driving efficiency. For example, the rolling element 21331 is a roller. In other embodiments, the output end of the lifting drive component 2133 can also be slidably connected to the feeding bin 2132. During the lifting process of the lifting drive component 2133, the output end of the lifting drive component 2133 adaptively slides relative to the feeding bin 2132, thereby preventing the feeding bin 2132 from interfering with the lifting of the lifting drive component 2133.

[0179] Optionally, see Figure 21The freeze-dried pellet feeding device 213 also includes a first elastic element 2137. One end of the first elastic element 2137 is connected to the fixed frame 2131, and the other end is connected to the feeding bin 2132. The rolling element 21331 can always be in contact with the outer peripheral surface of the feeding bin 2132 under the elastic force of the first elastic element 2137. That is, the first elastic element 2137 is always in an energy storage state and can apply a pulling force to the feeding bin 2132, so that the outer peripheral surface of the feeding bin 2132 is always in contact with the rolling element 21331. This ensures that the rolling element 21331 can always roll and cooperate with the outer peripheral surface of the feeding bin 2132 during the lifting and lowering process of the lifting drive 2133, thereby improving the stability of the feeding bin 2132 during the tilting process. At the same time, the first elastic element 2137 also has a reset function for the feeding bin 2132, so that the feeding bin 2132 can move downward and reset to a horizontal position. Specifically, when the lifting drive component 2133 descends, the feeding bin 2132 can descend accordingly under the pulling force of the first elastic element 2137, causing the feeding bin 2132 to automatically reset. For example, the first elastic element 2137 is a tension spring.

[0180] Of course, in other embodiments, the first elastic element 2137 may not be provided. For example, the rolling element 21331 at the output end of the lifting drive 2133 is rolled and connected to the loading bin 2132, or the output end of the lifting drive 2133 is slidably connected to the loading bin 2132, and the loading bin 2132 moves together when the output end of the lifting drive 2133 rises and falls, so that the loading bin 2132 can tilt at a preset angle and also return to its original position.

[0181] See Figure 12 , Figure 20 , Figure 21 and Figure 22 The freeze-dried pellet feeding device 213 also includes a cutting bin 2134 and a fourth blocking member 2136. The cutting bin 2134 is located at the discharge end of the feeding bin 2132 and has a cutting chamber 21340. The fourth blocking member 2136 is movably disposed in the cutting bin 2134 and has a third position and a fourth position. In the third position, the fourth blocking member 2136 extends into the cutting chamber 21340 and divides the cutting chamber 21340 into two independent chambers, a first chamber 21340a and a second chamber 21340b. The first chamber 21340a is used to communicate with the feeding bin 2132, and the second chamber 21340b is used to communicate with the storage bin 2111. In the fourth position, the fourth blocking member 2136 moves out of the cutting chamber 21340 so that the first chamber 21340a of the cutting chamber 21340 can communicate with the storage bin 2111.

[0182] Specifically, before the freeze-dried pellet feeding device 213 is activated, the fourth blocking member 2136 is in the third position, and the first chamber 21340a and the second chamber 21340b are independent of each other, that is, the feeding bin 2132 and the storage bin 2111 are not connected. After the freeze-dried pellet feeding device 213 is activated, the lifting drive member 2133 drives the feeding bin 2132 to tilt at a certain angle, and a portion of the freeze-dried pellets in the feeding bin 2132 enter the first chamber 21340a and are temporarily stored in the first chamber 21340a, that is, the first chamber 21340a can temporarily store a certain amount of freeze-dried pellets. When the feeding hopper 2132 is adjusted to a horizontal state again, and the fourth blocking component 2136 switches from the third position to the fourth position, the first chamber 21340a, the second chamber 21340b, and the storage hopper 2111 are connected. The freeze-dried balls temporarily stored in the first chamber 21340a enter the storage hopper 2111 through the second chamber 21340b, completing the quantitative feeding of the freeze-dried ball dispensing device 211.

[0183] That is, each time the freeze-dried ball feeding device 213 operates, it replenishes the freeze-dried ball dispensing device 211 with a quantitative amount of freeze-dried balls that can be contained in the first chamber 21340a, thereby achieving quantitative feeding of freeze-dried balls to the freeze-dried ball dispensing device 211, accurately controlling the amount of freeze-dried balls fed at one time, preventing the freeze-dried ball dispensing device 211 from jamming, ensuring the continuity of freeze-dried ball dispensing production, and improving the efficiency of freeze-dried ball dispensing.

[0184] It is understandable that since the freeze-dried pellets will be temporarily stored in the material receiving chamber 21340 before entering the storage silo 2111, the volume of the material receiving chamber 21340 determines the number of freeze-dried pellets entering the storage silo 2111. In other words, by setting up the material receiving chamber 21340, a quantitative supply of material to the storage silo 2111 can be achieved.

[0185] Furthermore, the discharge end of the cutting hopper 2134 is connected to the storage hopper 2111 of the freeze-dried pellet distribution device 211 via the conveying pipe 2135. When the fourth blocking member 2136 moves out of the cutting chamber 21340, the freeze-dried pellets in the cutting chamber 21340 automatically roll into the conveying pipe 2135 under their own gravity and enter the storage hopper 2111 along the conveying pipe 2135. The conveying pipe 2135 can guide the freeze-dried pellets into the storage hopper 2111 and ensure that the freeze-dried pellets are in a closed environment during the feeding process, preventing contamination of the freeze-dried pellets.

[0186] Optionally, the fourth blocking member 2136 can be controlled to move linearly by a linear drive component such as a cylinder, so as to achieve automatic control of the opening and closing of the material cutting chamber 21340.

[0187] Optionally, see Figure 22The feeding hopper 2132 includes a feeding hopper body 2132a and a feeding body 2132b. The feeding hopper body 2132a has an installation cavity, and the feeding body 2132b is fitted into the installation cavity. The feeding body 2132b has a hollow inner cavity, the cross-sectional area of ​​which gradually decreases towards the discharge end. That is, the inner cavity of the feeding body 2132b is funnel-shaped. When the feeding hopper 2132 is tilted, the freeze-dried pellets in the feeding body 2132b are more likely to automatically converge into the receiving cavity 21340 under their own gravity, improving the pellet discharge efficiency. Furthermore, this design ensures that the freeze-dried pellets in the feeding body 2132b only flow into the receiving cavity 21340 when the feeding hopper 2132 is tilted; when the feeding hopper 2132 is horizontal and not tilted, the freeze-dried pellets will not flow out. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space containing the hollow inner cavity of the feed body 2132b, not the cross-sectional area of ​​the feed body 2132b.

[0188] In addition, the split structure design of the feeding bin 2132 allows for the replacement of feeding bodies 2132b with appropriate volumes according to actual needs. That is, multiple feeding bodies 2132b with different volumes can be made, and the feeding body 2132b with the required volume can be replaced as needed, without having to replace the entire feeding bin 2132. This is convenient, quick, and more cost-effective.

[0189] Optionally, see Figure 22 The material receiving bin 2134 includes a material receiving bin body 2134a and a metering element 2134b. The material receiving bin body 2134a contains the aforementioned material receiving chamber 21340. The metering element 2134b is installed within the first chamber 21340a of the material receiving chamber 21340. The metering element 2134b has an inner cavity with an inlet and an outlet. The inlet communicates with the feeding bin 2132. When the fourth blocking element 2136 is in its third position, it blocks the outlet, allowing a certain amount of freeze-dried pellets to be temporarily stored in the inner cavity of the metering element 2134b. The material receiving bin 2134 is designed as a split structure, allowing the metering element 2134b to be replaced individually to change the single feeding amount of freeze-dried pellets. Specifically, the metering element 2134b is detachably installed within the first chamber 21340a, and multiple metering elements 2134b are provided, each with a different inner cavity volume. By using metering devices 2134b with different volumes, the single feeding amount of freeze-dried pellets can be changed, thus expanding the applicability of the freeze-dried pellet feeding equipment.

[0190] Optionally, the cross-sectional area of ​​the inner cavity of the metering unit 2134b gradually increases from the inlet to the outlet. That is, the inner cavity of the metering unit 2134b is funnel-shaped, and its inner wall surface is inclined downward relative to the discharge end of the feeding hopper 2132, which facilitates the automatic rolling of the freeze-dried balls from the feeding hopper 2132 into the metering unit 2134b, and ensures that the freeze-dried balls can be temporarily stored in the metering unit 2134b without flowing back into the feeding hopper 2132. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space containing the inner cavity of the metering unit 2134b, not the cross-sectional area of ​​the metering unit 2134b itself.

[0191] Optionally, a fourth air blowing device 2139 is provided on the material receiving bin 2134 (e.g., Figure 22 As shown, the outlet of the fourth air blowing device 2139 is connected to the material receiving chamber 21340 and is located near the discharge end of the feeding hopper 2132 in the material receiving chamber 21340. It is used to blow the freeze-dried balls in the material receiving chamber 21340 into the storage hopper 2111. The air blowing by the fourth air blowing device 2139 assists in feeding the freeze-dried balls in the metering element 2134b in the material receiving chamber 21340 into the conveying pipe 2135, allowing the freeze-dried balls to enter the storage hopper 2111 of the freeze-dried ball dispensing device 211 more smoothly, thus improving feeding efficiency. Since the outlet of the fourth air blowing device 2139 is at the end of the material receiving chamber 21340 near the feeding hopper 2132, it further prevents the freeze-dried balls from flowing back into the feeding hopper 2132. For example, the fourth air blowing device 2139 can be an air pump or the like, as long as it can generate a stable airflow.

[0192] See Figure 20 and Figure 22 The feeding hopper 2132 has a feed inlet 21320, and a feed hopper 2138 is provided at the feed inlet 21320. The feed hopper 2138 has a guide ramp for guiding the freeze-dried balls to the feed inlet 21320. The feed hopper 2138 expands the feeding space, which is more conducive to adding freeze-dried balls into the feeding hopper 2132, improving the feeding efficiency of freeze-dried balls, and at the same time preventing the freeze-dried balls from falling to the outside. For details, please refer to... Figure 22 The guide slope is set downward along the direction close to the feed inlet 21320.

[0193] Optionally, see Figure 9 , Figure 23 and Figure 24 Both the first conveyor line 22 and the second conveyor line 23 include a base 221, a conveying device 222, and a protective device 223. The conveying device 222 includes a conveyor belt 2221 tractably disposed on the base 221, and a carrier 10 carrying the reaction disc is placed on the conveyor belt 2221. The protective device 223 is disposed on the base 221 and defines a closed conveying space 224 on the base 221, within which the conveying device 222 is located.

[0194] It is understood that the aforementioned enclosed conveying space 224 has an inlet and an outlet. The carrier 10 carrying the reaction plate enters from the inlet of the conveying space 224 and is placed on the conveyor belt 2221. After the reaction plate is loaded with balls, the conveyor belt 2221 then conveys the carrier 10 to the outlet of the conveying space 224, so that the carrier 10 carries the reaction plate into the next process.

[0195] By setting a protective device 223 on the substrate 221 and arranging the conveying device 222 in the conveying space 224, the reaction disk is always in the relatively closed conveying space 224 during the process of the carrier 10 carrying the reaction disk flowing on the conveyor belt 2221 of the conveying device 222. This can prevent dust from falling on the reaction disk and prevent other objects from falling on the reaction disk, prevent the freeze-dried balls on the reaction disk from coming into contact with foreign objects, thereby preventing the freeze-dried balls from being contaminated and ensuring the accuracy of the freeze-dried ball reaction test results.

[0196] Optionally, the conveying device 222 further includes a drive mechanism (not shown) and a transmission wheel 2222. The conveyor belt 2221 is wound around the transmission wheel 2222. The output end of the drive mechanism is connected to the transmission wheel 2222 for driving the transmission wheel 2222 to rotate and drive the conveyor belt 2221 to achieve the conveying of the carrier 10. For example, the drive mechanism is a rotary motor.

[0197] See Figure 23 and Figure 24 The protective device 223 includes a first protective plate 2231, a second protective plate 2232, and a cover plate 2233. The first protective plate 2231 and the second protective plate 2232 are respectively disposed on both sides of the conveying device 222 along the width direction. The cover plate 2233 is located above the conveying device 222, with one end connected to the first protective plate 2231 and the other end connected to the second protective plate 2232. The cover plate 2233, the first protective plate 2231, the second protective plate 2232, and the cover plate 2233 cooperate to cover the carrier 10 carrying the reaction disc on the conveyor belt 2221, isolating the reaction disc on the carrier 10 from the outside and preventing contamination of the freeze-dried balls on the reaction disc. The width direction of the conveying device 222 is perpendicular to the conveying direction of the conveyor belt 2221.

[0198] Furthermore, the base 221 is provided with a first mounting plate 2211 and a second mounting plate 2212 on both sides of the conveying device 222 along the width direction. Conveyor belts 2221 are driven onto the sides of both the first mounting plate 2211 and the second mounting plate 2212 facing each other. A first protective plate 2231 is fixedly installed on the first mounting plate 2211, and a second protective plate 2232 is fixedly installed on the second mounting plate 2212. That is, there are two rows of conveyor belts 2221 in the conveying space 224. One side of the carrier 10 rests on one row of conveyor belts 2221, and the other side of the carrier 10 rests on the other row of conveyor belts 2221, making the movement of the carrier 10 more stable. The first mounting plate 2211 and the second mounting plate 2212 provide a mounting base for the first protective plate 2231 and the second protective plate 2232, so that the first protective plate 2231, the second protective plate 2232 and the cover plate 2233 can be erected above the conveying device 222 and cover the conveying device 222.

[0199] See Figure 23 and Figure 24 and combined Figure 3 The cover plate 2233 of the protective device 223 has an installation space directly opposite the ball-planting station 24. A freeze-dried ball guide device 220 is installed within this space, and the freeze-dried ball guide device 220 is used to fit against the reaction tray on the carrier 10. That is, the cover plate 2233 also provides an installation base for the freeze-dried ball guide device 220, allowing it to be suspended above the ball-planting station 24. This ensures that the freeze-dried ball guide device 220 does not interfere with the movement of the reaction tray on the conveyor belt 2221, while also allowing the freeze-dried ball dispensing equipment 212 to plant the freeze-dried balls into the ball-planting holes of the reaction tray via the freeze-dried ball guide device 220.

[0200] See Figure 25The freeze-dried ball guiding device 220 includes a fixed support 2201, a guide plate 2202, and a plug-in plate 2203. The fixed support 2201 is configured to be connected to the cover plate 2233. The guide plate 2202 is disposed on the fixed support 2201. The plug-in plate 2203 is stacked on the side of the guide plate 2202 facing away from the reaction plate. The plug-in plate 2203 is used to fit with the reaction plate. The guide plate 2202 is provided with multiple guide holes, and the plug-in plate 2203 is provided with plug-in holes that correspond to and communicate with the multiple guide holes. The reaction plate to be planted with balls has multiple ball planting holes. After the reaction plate and the plug-in plate 2203 are fitted together, the multiple plug-in holes, multiple guide holes, and multiple ball planting holes are connected in a corresponding manner. The discharge nozzle of the freeze-dried ball dispensing equipment 212 is inserted into the corresponding plug-in hole so that the freeze-dried balls can accurately fall from the guide hole into the corresponding ball planting hole. The guide holes guide the freeze-dried pellets to accurately fall into the corresponding pelleting holes, preventing them from rolling off the reaction plate and avoiding breakage and powder loss. During pelleting, the freeze-dried pellets will not come into contact with foreign objects, preventing contamination. The insertion holes ensure accurate alignment between the discharge nozzle and the guide holes, improving the efficiency of freeze-dried pellet dispensing.

[0201] See Figure 25 The fixed support 2201 has a protruding support part 22011, and the guide plate 2202 has a protruding connecting part 22021 on its edge. The connecting part 22021 is mounted on the support part 22011 and fixedly connected to the support part 22011, which can provide sufficient connection area between the guide plate 2202 and the fixed support 2201, thereby improving the installation stability of the guide plate 2202 on the fixed support 2201.

[0202] In this embodiment, the first conveyor line 22 and the second conveyor line 23 have the same structure. Taking the first conveyor line 22 as an example, see [link to documentation]. Figure 24 The first conveyor line 22 also includes a lifting device 225 located at the freeze-dried ball docking station. The lifting device 225 is used to lift the carrier 10, which is being conveyed to the ball-planting station 24, so that the reaction tray on the carrier 10 fits against the freeze-dried ball guide device 220. Then, the discharge nozzle of the freeze-dried ball dispensing device 212 is inserted into the insertion hole of the insertion plate 2203, so that the freeze-dried balls fall into the corresponding ball-planting holes through the guide holes of the guide plate 2202. The lifting device 225 allows the reaction tray on the carrier 10 to selectively fit or separate from the freeze-dried ball guide device 220, completing the conveying of the reaction tray and the dispensing of freeze-dried balls within the reaction tray.

[0203] See Figure 24A limiting member 2213 is provided on the base 221 to limit the travel of the lifting device 225 in lifting the carrier 10. When the lifting device 225 lifts the carrier 10 to contact the limiting member 2213, the carrier 10 can no longer move upward, which can prevent the carrier 10 from moving beyond its travel range and avoid hard contact between the reaction plate and the freeze-drying ball guide device 220, thus protecting the reaction plate and the freeze-drying ball guide device 220.

[0204] For example, the lifting device 225 may include a cylinder and a lifting plate disposed at the output end of the cylinder. The cylinder drives the lifting plate to rise to contact the carrier 10 and lifts the carrier 10 to the point where the reaction plate on the carrier 10 fits against the freeze-dried ball guide device 220.

[0205] See Figure 24 The first conveyor line 22 also includes a blocking device 226, located downstream of the ball-planting station 24. The blocking device 226 restricts the carrier 10 on the conveyor belt 2221 from moving beyond its designated position at the ball-planting station 24, preventing the carrier 10 from overtraveling on the conveyor belt 2221, ensuring accurate alignment of the lifting device 225 with the carrier 10, and guaranteeing that the reaction disc on the carrier 10 is directly aligned with the freeze-dried ball guide device 220. Exemplarily, the blocking device 226 may include a cylinder and a blocking block disposed at the cylinder output end. The cylinder drives the blocking block to rise and fall to block or avoid the carrier 10.

[0206] See Figure 26 The carrier 10 includes a carrier body 101 and a clamping device 102. A positioning platform 1011 is provided on the carrier body 101 for placing the reaction disk 20. The clamping device 102 includes a first gripper 1021 and a second gripper 1022 movably disposed on the carrier body 101. The first gripper 1021 and the second gripper 1022 are distributed on opposite sides of the positioning platform 1011. The first gripper 1021 and the second gripper 1022 tend to move towards each other to clamp and fix the reaction disk 20. Furthermore, the first gripper 1021 and the second gripper 1022 can move away from each other under external force to release the reaction disk 20. The positioning platform 1011, in cooperation with the first gripper 1021 and the second gripper 1022, can securely limit the reaction disk 20 onto the carrier body 101.

[0207] Specifically, a first positioning post is provided at the center of the positioning platform 1011, and a first positioning hole is provided at the center of the reaction disk. The first positioning post and the first positioning hole are inserted to ensure that the reaction disk is stacked directly above the positioning platform 1011. The positioning platform 1011 is provided with a second positioning post offset from the center, and the reaction disk is provided with a corresponding second positioning hole. The second positioning post and the second positioning hole are inserted to position the reaction disk relative to the circumferential position of the positioning platform 1011, ensuring the correct positioning of the multiple ball-planting holes on the reaction disk. This also further improves the stability of the reaction disk on the positioning platform 1011.

[0208] See Figure 26 The clamping device 102 further includes a drive gripper 1023 movably disposed on the carrier body 101 along a preset direction. Both the first gripper 1021 and the second gripper 1022 have a pushing structure on their respective sides. The drive gripper 1023 is at least partially located between the two pushing structures. When the drive gripper 1023 moves along the preset direction, it can slide and engage with the two pushing structures to drive the first gripper 1021 and the second gripper 1022 to move in opposite directions. That is, the drive gripper 1023 can simultaneously apply external force to the first gripper 1021 and the second gripper 1022 to make them move synchronously in opposite directions.

[0209] In this embodiment, the first gripper 1021, the second gripper 1022, and the driving gripper 1023 are all slidably disposed on the carrier body 101. Second elastic members extending along corresponding sliding directions are provided between the first gripper 1021 and the carrier body 101, between the second gripper 1022 and the carrier body 101, and between the driving gripper 1023 and the carrier body 101. When the external force is removed, the first gripper 1021 and the second gripper 1022 can move towards each other under the elastic force of the corresponding second elastic members to clamp and fix the reaction disk. The driving gripper 1023 can move towards the reaction disk under the elastic force of the corresponding second elastic member until it abuts against the reaction disk, further restricting the position of the reaction disk.

[0212] The loading and unloading mechanism 1 includes a transfer device 11 and a loading line 12 and an unloading line 13 arranged at intervals. Both the loading line 12 and the unloading line 13 are used to transport the carriers 10 that carry the reaction trays. The transfer device 11 can place empty reaction trays on the carriers 10 of the loading line 12, and the transfer device 11 can remove full-load reaction trays from the carriers 10 of the unloading line 13, realizing automatic loading and unloading of reaction trays. Here, a full-load reaction tray refers to a reaction tray that has been transferred to the unloading line 13 after the ball-planting operation is completed. A full-load reaction tray includes reaction trays with ball-planting that meets the requirements, as well as reaction trays with unqualified ball-planting.

[0213] Both the first and second conveyor lines are used to transport the carrier 10 that carries the reaction discs. The first conveyor line is located on one side of the loading line 12, and the second conveyor line is located on one side of the unloading line 13. Both the first and second conveyor lines have at least one ball-planting station 24. At least one ball-planting mechanism is arranged sequentially along the conveying direction of the carrier 10. The ball-planting mechanism includes a freeze-dried ball dispensing module 21. At least one freeze-dried ball dispensing module 21 is provided at each ball-planting station 24. The freeze-dried ball dispensing module 21 is used to plant balls onto the reaction discs on the corresponding first and / or second conveyor lines.

[0214] In this embodiment, at least one ball-planting mechanism refers to the ability to set one, two, or more ball-planting mechanisms. The first conveyor line is a single, continuous conveyor line, and the second conveyor line is a single, continuous conveyor line. The loading line 12 and the unloading line 13 are connected, and the first and second conveyor lines are connected at the ends away from the loading and unloading mechanisms, forming a circular conveyor line. Multiple ball-planting mechanisms can be arranged above the entire first conveyor line, and multiple ball-planting mechanisms can also be arranged above the entire second conveyor line. During the process of the carrier 10 carrying the reaction discs flowing on the first and second conveyor lines, the freeze-dried ball dispensing module 21 of the ball-planting mechanism plants balls onto the reaction discs on the corresponding first and second conveyor lines.

[0215] The automatic freeze-dried pellet packaging system includes a loading and unloading mechanism 1 for loading and unloading the reaction trays, a first conveyor line and a second conveyor line for conveying the carrier 10 that carries the reaction trays, and a pellet-planting mechanism for planting pellets onto the reaction trays on the first and second conveyor lines, thereby achieving automatic packaging of freeze-dried pellets on the reaction trays and improving the packaging efficiency of freeze-dried pellets.

[0216] Example 3

[0217] This embodiment also provides an automatic lyophilized bulb dispensing method, applied to the automatic lyophilized bulb dispensing system as described in Embodiment 1 or Embodiment 2. The automatic lyophilized bulb dispensing method includes the following steps:

[0218] The transfer device 11 places an empty reaction tray onto the carrier 10 of the feed line 12;

[0219] The feeding line 12 transports the carrier 10 carrying the reaction plate to the first conveyor line 22, and the carrier 10 carrying the reaction plate can be transported to the unloading line 13 through the first conveyor line 22 and the second conveyor line 23.

[0220] During the process of the carrier 10 carrying the reaction plate being transported to the unloading line 13, the freeze-dried ball dispensing module 21 inserts balls into the reaction plate on the corresponding first conveying line 22 or second conveying line 23.

[0221] The transfer device 11 removes the fully loaded reaction plate from the unloading line 13 and transfers it to the designated position.

[0222] Specifically, the first clamping component 111 of the transfer device 11 grasps an empty reaction tray and places it on the carrier 10 of the feeding line 12. The feeding line 12 then transports the carrier 10 carrying the reaction tray to the first conveyor line 22. The carrier 10 carrying the reaction tray can then be transferred to the unloading line 13 via the first conveyor line 22 and the second conveyor line 23. During this process, the freeze-dried ball dispensing module 21 at the ball-planting station 24 of the first and second conveyor lines 22 and 23 plants balls onto the corresponding reaction trays. When the carrier 10 carrying the reaction tray is transferred to the unloading line 13, the ball planting is complete. Then, the second clamping component 112 of the transfer device 11 removes the fully loaded reaction tray from the carrier 10 of the unloading line 13 and transfers it to a designated position, thus completing the automatic dispensing of freeze-dried balls. The entire process requires no manual operation, resulting in high efficiency. Furthermore, the freeze-dried ball dispensing process avoids human contact with the reaction trays or freeze-dried balls, preventing contamination.

[0223] In this embodiment, the qualified full-load reaction disks are placed on the second tray 151 at the unloading station 15, and the unqualified reaction disks are placed on the buffer device 181 at the non-qualified product buffer station 18.
