During this period, the freeze-dried ball packaging module 21 at the ball planting station 24 of the first conveying line 22 and the second conveying line 23 plants balls on the corresponding reaction disk. When the carrier 10 carrying the reaction disk is transferred to the unloading line 13, the ball planting of the reaction disk is completed, and then the fully loaded reaction disk on the carrier 10 of the unloading line 13 is removed and transferred to a designated position (for example, in a tray or the next processing step) by the transfer device 11, that is, the automatic packaging of the freeze-dried balls is completed, and no manual operation is required throughout the process, and the efficiency of freeze-dried ball packaging is high. In addition, there is no manual contact with the reaction disk or freeze-dried balls during the entire process of freeze-dried ball packaging, which can avoid contamination of the freeze-dried balls.

[0120] For example, see Figure 1 and Figure 2 There are four ball planting mechanisms 2, and each of the first conveyor line body 22 and the second conveyor line body 23 of the ball planting mechanism 2 has two ball planting stations 24, and each ball planting station 24 is provided with four freeze-dried ball packaging modules 21, such as Fig. 9 and Fig.11 As shown, the four freeze-dried ball packaging modules 21 can output freeze-dried balls of the same type or different types to meet the ball planting requirements of different reaction trays and improve the adaptability of the freeze-dried ball automatic packaging system.

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

[0122] Optionally, see Figure 1 and Figure 2The loading and unloading mechanism 1 is provided with a first protective cover 19, which is arranged outside the loading line 12 and the unloading line 13. The setting of the first protective cover 19 can make the loading and unloading of the reaction disk in a relatively closed space, ensuring that the entire circulation process of the reaction disk is in a relatively clean space to prevent the contamination of the freeze-dried balls.

[0123] See also Figure 1 and Figure 2 The ball implanting mechanism 2 is provided with a second protective cover 26, which is provided outside the first conveying line body 22 and the second conveying line body 23. The second protective cover 26 can keep the reaction plate in a relatively closed space during the ball implanting process to prevent the freeze-dried balls on the reaction plate from being contaminated.

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

[0125] Specifically, see Figure 7 The first clamping assembly 111 includes a clamping driving member 1111 and two clamping claws 1112. The clamping driving member 1111 can drive the two clamping claws 1112 to clamp or release the reaction disk 20, and the clamping driving member 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 a designated position of the carrier 10.

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

[0127] See also 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-axis module 113 is perpendicular to each other. The Y-axis module 1132 extends along the conveying direction of the loading line 12. The first clamping component 111 is installed on the Z-axis module 1133. The position of the first clamping component 111 in the X direction, the Y direction and the Z direction can be adjusted by the three-axis module 113, so that the first clamping component 111 can flexibly take and place the reaction disk.

[0128] Furthermore, the loading station 14 has a first area and a second area, the first area is used to stack the first tray 141 with empty reaction trays, and the second area is used to stack the empty first tray 141. Multiple empty reaction trays can be placed in the first tray 141, and the first clamping assembly 111 clamps the empty reaction trays from the first tray 141 in the first area. After the empty reaction trays in the first tray 141 are taken out, 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 tray loading work and improve the loading efficiency.

[0129] Optionally, see Figure 2 , Figure 3 and Figure 5 A material unloading station 15 is provided on one side of the material unloading line 13, and a second tray 151 for holding a fully loaded reaction disc is stacked at the material unloading station 15. The transfer device 11 includes a second clamping assembly 112, and the second clamping assembly 112 is used to clamp the fully loaded reaction disc from the carrier 10 of the material unloading line 13, and place the fully loaded reaction disc in the second tray 151, so as to realize automatic unloading of the fully loaded reaction disc. In this embodiment, the second clamping assembly 112 has the same structure as the first clamping assembly 111, and 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 fully loaded reaction disc, so as to remove the fully loaded reaction disc from the carrier 10 and transfer it to a designated position.

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

[0131] See also Figure 5 and Figure 8 The transfer device 11 has two Z-axis modules 1133 , and the first clamping assembly 111 and the second clamping assembly 112 are respectively mounted on the two Z-axis modules 1133 , so that the first clamping assembly 111 and the second clamping assembly 112 can flexibly take and place the reaction disk.

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

[0133] Optionally, see Figure 3 and Figure 5 The loading and unloading mechanism 1 also includes a first visual inspection device 16. The first clamping component 111 places the clamped empty reaction disc on the carrier 10 of the loading line 12 according to the information detected by the first visual inspection device 16, ensuring that the placement position of the reaction disc on the carrier 10 is correct. Specifically, the first visual inspection device 16 can take a picture of the carrier 10 to obtain the positioning information on the carrier 10. The first clamping component 111 controls the clamping claw 1112 to clamp the reaction disc and rotate it to a certain angle according to the positioning information, so that the reaction disc is placed at the specified position of the carrier 10, ensuring that the reaction disc can stably flow on the first conveying line 22 and the second conveying line 23, and the subsequent ball planting process can be carried out normally. Exemplarily, the first visual inspection device 16 is a visual camera.

[0134] See also Figure 6 , a static electricity removal device 121 is provided on the feeding line 12, and the static electricity removal device 121 is used to remove static electricity from the reaction disk on the feeding line 12, so as to prevent the reaction disk from affecting the ball planting due to the presence of static electricity, and ensure that the subsequent ball planting process can proceed smoothly. Exemplarily, the static electricity removal device 121 can be an ion wind knife, which blows ion wind to the reaction disk, so that the positive and negative ions interact with the static charge on the surface of the object, neutralize or separate the static charge, and thus eliminate static electricity. In other embodiments, the static electricity removal device 121 can also be an ion blower, an ion wind 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, and the loading and unloading mechanism 1 further includes a second visual inspection device 17, which is used to inspect whether the fully loaded reaction tray on the unloading line 13 is qualified. The second clamping assembly 112 can place the fully loaded reaction tray that has passed the inspection on the second tray 151, and the second clamping assembly 112 can place the fully loaded reaction tray that has failed the inspection in the non-conforming product buffer station 18. The second visual inspection device 17 can sort out the non-conforming products in time, prevent the non-conforming 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 a picture of the fully loaded reaction tray on the carrier 10 to obtain image information of the fully loaded reaction tray, and analyze whether the quality of the freeze-dried balls on the reaction tray meets the requirements based on the image information to determine whether the fully loaded reaction tray after ball planting is qualified. Among them, the analysis items may include but are not limited to pits on the freeze-dried balls (for example, pits with a depth of more than 0.5 mm are unqualified), burrs, peeling, cracks, and the number of freeze-dried balls on the reaction tray. Exemplarily, the second visual inspection device 17 is a visual camera.

[0137] See also Figure 3 and Fig.13 The non-conforming product buffer station 18 is provided with a buffer device 181, and the second clamping assembly 112 places the unqualified fully loaded reaction disc on the buffer device 181 for subsequent recycling. Exemplarily, the buffer device 181 includes a carrying platform and a limiting column arranged on the carrying platform, and the unqualified reaction disc is passed through the limiting column, and multiple unqualified reaction discs are stacked.

[0138] Optionally, see Figure 1 and Figure 2 A first transfer line 3 is provided between the loading line 12 and the unloading line 13, and the first transfer line 3 is used to transfer the empty carrier 10 on the unloading line 13 to the loading line 12. That is, the loading line 12 is connected to the unloading line 13 through the first transfer line 3, so that the empty carrier 10 on the unloading line 13 can be transferred to the loading line 12 via the first transfer line 3, so as to realize the recycling of the carrier 10, further improve the loading efficiency, and then improve the freeze-dried ball packaging efficiency.

[0139] See also 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 farthest from the loading and unloading mechanism 1, and 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 line 22 and the second conveyor line 23 of a plurality of ball planting mechanisms 2 are connected by the second transfer line 4, so that the loading line 12, the plurality of first conveyor lines 22, the plurality of second conveyor lines 23 and the unloading line 13 form a closed-loop conveyor line, so that the carrier 10 can carry the reaction tray to carry out the same or different types of freeze-dried balls at different ball planting stations 24.

[0140] See also Figure 1 , Figure 3 and Figure 5 A third transfer line 5 is provided between the loading and unloading mechanism 1 and the adjacent ball planting mechanism 2, and the third transfer line 5 is used to transport the carrier 10 on the loading line 12 to the first conveying line 22, and to transport the carrier 10 on the second conveying line 23 to the unloading line 13. That is, the carrier 10 is transferred between the loading and unloading mechanism 1 and the ball planting mechanism 2 through the third transfer line 5, ensuring that the carrier 10 on the loading line 12 can be smoothly transferred to the first conveying line 22, and ensuring that the carrier 10 on the second conveying 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. Fig.14Taking the third transfer line 5 as an example, the third transfer line 5 includes a guide rail and a carrying platform slidably arranged on the guide rail, the guide rail extends along the conveying direction of the carrier 10, and a conveyor belt is arranged on the carrying platform. The loading line 12 conveys the carrier 10 to the conveyor belt of the carrying platform, and the carrying platform drives the carrier 10 to slide along the guide rail to the first conveying line 22, and the conveyor belt then conveys the carrier 10 to the first conveying line 22.

[0142] In other embodiments, the third transfer line 5 may not be provided, 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 ball planting mechanism 2 is provided 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 of the freeze-dried ball reaction test to the reaction disk, so as to realize automatic loading of the reagent package. In this embodiment, the middle part of the reaction disk has a groove for holding the reagent package, and the reagent loading device 6 places the reagent package in the groove. Exemplarily, one reagent package is placed on each reaction disk. When the freeze-dried ball reaction test is performed subsequently, it is only necessary to puncture the reagent package to fuse the reagent with the freeze-dried ball, and the reaction test data of the freeze-dried ball can be detected by the detection instrument.

[0144] This embodiment is in, see Figure 1 and Figure 2 The reagent loading device 6 is located at the leftmost end of the whole machine, that is, arranged at the corner of the whole machine, which can avoid the reagent loading device 6 occupying the manual channels on both sides of the whole machine. The space layout is reasonable and can save the factory space to the maximum extent.

[0145] See also Fig.10 The reagent loading device 6 includes a vibration plate 61 and a reagent pack picking device 62. The reagent pack picking device 62 is located above the second conveying line body 23 of the last ball implanting mechanism 2. The vibration plate 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 the reagent pack on the reaction plate of the second conveying line body 23.

[0146] Optionally, see Fig.11 , Fig.12 , Fig.15 and Fig.16The freeze-dried ball dispensing module 21 includes a freeze-dried ball dispensing device 211, which includes a storage bin 2111, a base 2112 and a first detection device 2114. The storage bin 2111 is used to hold freeze-dried balls. The base 2112 is disposed below the storage bin 2111. The base 2112 is provided with a dispensing channel 21121 connected to the storage bin 2111. The dispensing channel 21121 has a blocking space 21122 for blocking a single freeze-dried ball, and the dispensing channel 21121 is selectively opened or closed at the blocking space 21122. The first detection device 2114 is used to detect whether there are freeze-dried balls in the blocking space 21122. When there are freeze-dried balls in the blocking space 21122, the dispensing channel 21121 is opened.

[0147] Specifically, when the freeze-dried balls in the storage bin 2111 enter the distribution channel 21121 and reach the blocking space 21122, the first detection device 2114 can detect the presence of freeze-dried balls in the blocking space 21122, and then the distribution channel 21121 is turned on, and the freeze-dried balls in the blocking space 21122 automatically enter the equipment of the next processing step along the distribution channel 21121 or fall into the container 30 for holding freeze-dried balls, thereby realizing the distribution of freeze-dried balls. Since the blocking space 21122 can only accommodate a single freeze-dried ball, only one freeze-dried ball can fall into the equipment of the next process or fall into the container 30 for holding freeze-dried balls at a time, thereby realizing accurate control of the distribution quantity of freeze-dried balls. The setting of the first detection device 2114 can control the opening and closing of the distribution channel 21121 according to whether there are freeze-dried balls in the blocking space 21122, thereby realizing fully automatic distribution of freeze-dried balls and ensuring the accuracy of distribution. Moreover, during the material distribution process, the freeze-dried balls are always in the closed environment of the storage bin 2111 and the material distribution channel 21121, which can isolate the external environment, avoid cross contamination caused by contact between the freeze-dried balls and foreign objects, and ensure the packaging quality of the freeze-dried balls.

[0148] In this embodiment, the lateral space of the material distribution channel 21121 allows only a single freeze-dried ball to pass through, and the width of the material distribution channel 21121 is defined as D, and the diameter of the freeze-dried ball is defined as d, d<D<2d, so as to ensure that the lateral space of the material distribution channel 21121 allows only a single freeze-dried ball to pass through, and the freeze-dried ball can be ensured to move smoothly in the material distribution channel 21121. Exemplarily, the width of the material distribution channel 21121 is 0.2 mm larger than the diameter of the freeze-dried ball.

[0149] See also Fig.12The freeze-dried ball dispensing device 211 also includes a first blocking member 2113 movably arranged on the base 2112, and the first blocking member 2113 has a first position and a second position. When in the first position, the first blocking member 2113 extends into the dispensing channel 21121 and sets up a blocking space 21122 in the dispensing channel 21121. When in the second position, the first blocking member 2113 moves out of the dispensing channel 21121 to open the dispensing channel 21121, so that the freeze-dried balls flow out of the dispensing channel 21121, thereby realizing the selective opening or closing of the dispensing channel 21121.

[0150] Furthermore, the linear movement of the first blocking member 2113 can be controlled by a linear driving member such as a cylinder to extend into or move 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, the optical fiber detection method is used to determine whether there are freeze-dried balls in the blocking space 21122, with high detection efficiency and accurate detection. Exemplarily, the optical fiber detection element is an optical fiber sensor. In other embodiments, the first detection device 2114 can also be an infrared sensor, etc., which detects whether there are freeze-dried balls in the blocking space 21122 through an infrared sensor.

[0152] Optionally, see Fig.12 and Fig.15 , the material distribution channel 21121 includes a first channel 21121a, a second channel 21121b and a third channel 21121c which are connected in sequence, the first channel 21121a is connected to the material storage bin 2111, the second channel 21121b is inclined relative to the horizontal plane and has a slope toward the first channel 21121a; when in the first position, the first blocking member 2113 extends into the third channel 21121c, and is surrounded at the connection between the third channel 21121c and the second channel 21121b to form a blocking space 21122. That is, the blocking space 21122 is located at the higher end of the second channel 21121b, and the freeze-dried balls in the material storage bin 2111 are located at the lower end of the second channel 21121b after entering from the first channel 21121a. Since the blocking space 21122 can only accommodate 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, and 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 is switched to the second position, it can further ensure that only one freeze-dried ball can be output from the third channel 21121c, thereby accurately controlling the amount of freeze-dried balls distributed.

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

[0154] Furthermore, the inner wall of the second channel 21121b and the inner wall of the third channel 21121c are connected in an arc-shaped transition to form an arc-shaped blocking surface 21121d (eg, Fig.15 As shown in the figure, a blocking space 21122 is formed between the arc-shaped blocking surface 21121d and the first blocking member 2113. 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 setting of the arc-shaped blocking surface 21121d makes the shape of the blocking space 21122 more suitable for the spherical freeze-dried balls, which can prevent the freeze-dried balls from being stuck in the blocking space 21122. After the first blocking member 2113 is switched to the second position, it is ensured that the freeze-dried balls can smoothly fall into the third channel 21121c. At the same time, the arc-shaped blocking surface 21121d can prevent the freeze-dried balls from being scratched and damaged. The curvature of the arc-shaped blocking surface 21121d can be designed according to the adaptability of the diameter of the freeze-dried balls, as long as it is ensured that only a single freeze-dried ball can be allowed to exist in the blocking space 21122.

[0155] Optionally, the freeze-dried ball dispensing device 211 also includes a first blowing device 21123 disposed on the base 2112, and the air outlet end of the first blowing device 21123 is used to blow air to the lower end of the second channel 21121b, so that the freeze-dried ball moves along the second channel 21121b to the blocking space 21122. Driving the freeze-dried ball to move by blowing can prevent foreign objects from directly contacting the freeze-dried ball, and further prevent the freeze-dried ball from being contaminated. At the same time, the airflow driving method is relatively gentle, which can prevent the freeze-dried ball from being damaged or falling powder, and ensure the quality of the freeze-dried ball. Exemplarily, the first blowing device 21123 can be an air pump, etc.

[0156] See also Fig.12 and Fig.15 The base 2112 is provided with an exhaust channel 21125, one end of which is connected to the blocking space 21122, and the other end of which 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 from flowing back and causing the freeze-dried balls to roll back into the second channel 21121b, and ensuring that the freeze-dried balls can be stably stored in the blocking space 21122.

[0157] Optionally, a limiting groove 21131 (such as Fig.15 As shown in the figure, when the first blocking member 2113 is in the first position, the freeze-dried balls in the blocking space 21122 can be confined in the limiting groove 21131, so that the freeze-dried balls are temporarily and stably stored in the blocking space 21122. In this embodiment, after the freeze-dried balls reach the blocking space 21122, a part of them is located in the limiting groove 21131, and the center of gravity of the freeze-dried balls falls in the limiting groove 21131, that is, the center of gravity of the freeze-dried balls is in the third channel 21121c (that is, the center of gravity of the freeze-dried balls deviates from the second channel 21121b). When the first blocking member 2113 moves from the first position to the second position, the freeze-dried balls can fall rapidly under the action of their own gravity, which effectively improves the falling efficiency of the freeze-dried balls and ensures that the freeze-dried balls will not fall back to the second channel 21121b.

[0158] In this embodiment, the groove 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 temporarily stored in the limiting groove 21131. At the same time, the arc-shaped surface can prevent the freeze-dried balls from being scratched, thereby ensuring the quality of the freeze-dried balls after material distribution.

[0159] Optionally, the freeze-dried ball dispensing device 211 further includes a second blowing device 2116 (such as Fig.17 As shown in the figure, the air outlet of the second blowing device 2116 is used to blow air into the storage bin 2111 to move the freeze-dried balls in the storage bin 2111, prevent the freeze-dried balls from being adsorbed together due to static electricity, and ensure that the freeze-dried balls can smoothly fall into the distribution channel 21121. Exemplarily, the second 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 which are connected, the second cavity is closer to the base 2112, and the cross-sectional area of ​​the second cavity gradually decreases towards the base 2112, so as to form an inclined flow-guiding wall in the second cavity. That is, the second cavity is funnel-shaped, so that the freeze-dried balls can automatically gather downward under the action of their own gravity and fall into the distribution channel 21121, thereby improving the ball-falling efficiency.

[0161] Furthermore, the storage bin 2111 is provided with an air inlet channel 21111 (such as Fig.17 As shown in the figure, the outlet of the air inlet channel 21111 is located at the bottom of the second cavity, which enables the airflow to enter from the bottom of the inner cavity of the storage bin 2111, thereby preventing the freeze-dried balls from gathering at the outlet of the storage bin 2111 and ensuring the normal falling of the balls. Furthermore, the inclination angle of the air inlet channel 21111 is the same or approximately the same as the inclination angle of the guide wall, which enables the airflow to act on more freeze-dried balls, thereby quickly breaking the aggregation state of the freeze-dried balls and ensuring the normal falling of the balls. Approximately the same here means that the air inlet channel 21111 is roughly parallel to the guide slope, for example, the difference in the inclination angles of the two can be within 5°.

[0162] See also Fig.12 and Fig.15 The freeze-dried ball dispensing device 211 also includes a third detection device 2115, which is used to detect the remaining amount of freeze-dried balls in the storage bin 2111. When the third detection device 2115 detects that the remaining amount of freeze-dried balls in the storage bin 2111 is lower than the set threshold, the freeze-dried ball dispensing device 211 sends a prompt signal to facilitate timely refilling of the storage bin 2111, thereby ensuring the working continuity of the freeze-dried ball dispensing device 211 and improving the dispensing efficiency. The refilling can be done manually or automatically by a machine.

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

[0164] Optionally, see Fig.11 and Fig.12 The freeze-dried ball dispensing module 21 includes a freeze-dried ball dispensing device 212 disposed below the freeze-dried ball dispensing device 211. The freeze-dried ball dispensing device 212 includes a device body 2121, a second detection device, and a material pushing device. The device body 2121 is provided with a cache channel 21211, a qualified channel 21212, and an unqualified channel 21213. One end of the cache channel 21211 is connected to the dispensing channel 21121, and the other end of the cache channel 21211 can selectively be connected to the qualified channel 21212 or the unqualified channel 21213. The second detection device is used to detect the number of freeze-dried balls in the cache channel 21211. When the number of freeze-dried balls in the cache channel 21211 is 1, the cache channel 21211 is connected to the qualified channel 21212. The pushing device is arranged on the device body 2121. When the number of freeze-dried balls in the buffer channel 21211 is greater than 1, the buffer channel 21211 is connected with the unqualified channel 21213, and the pushing device sends at least part of the freeze-dried balls in the buffer channel 21211 to the unqualified channel 21213. That is, the freeze-dried ball dispensing device 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 each time, thereby accurately controlling the number of freeze-dried balls entering the container 30 at a single time to be 1, and ensuring the accuracy of the freeze-dried ball dispensing dosage.

[0165] See also Fig.12 , Fig.18 and Fig.19The freeze-dried ball packaging equipment 212 also includes a second blocking member 2124 and a third blocking member 2125 movably arranged 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 cache channel 21211; the third blocking member 2125 can extend into the unqualified channel 21213 to separate the unqualified channel 21213 from the cache channel 21211, and by controlling the activities of the second blocking member 2124 and the third blocking member 2125, the cache channel 21211 is selectively connected to the qualified channel 21212 or the unqualified channel 21213.

[0166] Specifically, in the initial state, the qualified channel 21212 and the unqualified channel 21213 are not connected to the cache channel 21211, the lower end of the cache channel 21211 is closed, and the freeze-dried balls entering the cache channel 21211 are temporarily stored in the cache channel 21211. If it is detected that the number of freeze-dried balls in the cache 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 cache channel 21211, so that the freeze-dried balls in the cache channel 21211 flow out to the container 30 for storing freeze-dried balls through the qualified channel 21212, and the freeze-dried balls are packaged once.

[0167] If it is detected that the number of freeze-dried balls 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 is not connected to the buffer channel 21211), so as to connect the unqualified channel 21213 and the buffer channel 21211, and control the pusher to move part 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 is detected to be 1, the buffer channel 21211 can be connected with 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 member such as a cylinder to achieve automatic control of the opening and closing of the cache channel 21211 and the qualified channel 21212 and the unqualified channel 21213.

[0169] Optionally, the cache channel 21211 has a plurality of freeze-dried ball cache positions arranged sequentially from bottom to top, and each freeze-dried ball cache position can only accommodate a single freeze-dried ball. That is, the freeze-dried ball cache channel 21211 can only stack multiple freeze-dried balls sequentially from bottom to top. Fig.19, the second detection device includes a first detection member 2120a and a second detection member 2120b, and the first detection member 2120a and the second detection member 2120b are respectively used to detect whether there are freeze-dried balls in the two adjacent freeze-dried ball cache positions at the bottom in the cache channel 21211. Specifically, when the first detection member 2120a and the second detection member 2120b both detect the presence of freeze-dried balls, it indicates that the first and second freeze-dried ball cache positions counted from the bottom to the top in the cache channel 21211 both have freeze-dried balls, that is, there are at least two freeze-dried balls in the cache channel 21211, and the number of freeze-dried balls is greater than 1. At this time, the third blocking member 2125 is controlled to move out of the unqualified channel 21213 to connect the cache channel 21211 and the unqualified channel 21213. Then, the pushing device is controlled to operate to send at least part of the freeze-dried balls in the cache channel 21211 into the unqualified channel 21213. When the first detection component 2120a detects the presence of freeze-dried balls and the second detection component 2120b detects the absence of freeze-dried balls, it indicates that there is only one freeze-dried ball in the cache channel 21211. At this time, the third blocking component 2125 is controlled to extend into the unqualified channel 21213, and the second blocking component 2124 is controlled to move out of the qualified channel 21212. The freeze-dried balls can then fall into the qualified channel 21212, completing the packaging of the freeze-dried balls.

[0170] Optionally, the first detection member 2120a and the second detection member 2120b both include optical fiber detection elements, which can detect whether there are freeze-dried balls in the freeze-dried ball cache. That is, the freeze-dried ball cache is detected by optical fiber detection, and then the number of freeze-dried balls in the cache channel 21211 is determined to be 1, which has high detection efficiency and accurate detection.

[0171] Optionally, the pushing device includes a third blowing device 2123 (such as Fig.12 As shown in the figure, the third blowing device 2123 can blow the freeze-dried balls in the cache channel 21211 into the non-qualified channel 21213, so that the freeze-dried balls move to the non-qualified channel 21213 under the impetus of the airflow. The method of driving the freeze-dried balls to move by blowing can avoid direct contact between foreign objects and the freeze-dried balls, and prevent the freeze-dried balls from being contaminated. At the same time, the airflow driving method is relatively gentle, which can prevent the freeze-dried balls from being damaged or falling powder, and ensure the quality of the freeze-dried balls. Exemplarily, the third blowing device 2123 can be an air pump, etc.

[0172] Further, see Fig.18The device body 2121 is provided with an air inlet space 21214, the air outlet end of the third air blowing device 2123 is connected to the air inlet space 21214, and the air inlet space 21214 has an air inlet 21214a extending obliquely toward the non-qualified channel 21213. After the air flow 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 inlet 21214a, so that the freeze-dried balls are moved into the non-qualified channel 21213 under the impetus of the air flow. Since the air inlet 21214a extends obliquely toward the non-qualified channel 21213, the air flow can always flow in the direction of the non-qualified channel 21213, so as to drive the freeze-dried balls to smoothly enter the non-qualified channel 21213 from the buffer channel 21211, thereby improving the packing efficiency of the freeze-dried balls.

[0173] Of course, in other optional embodiments, the pusher device can also be a push rod movably arranged on the device body 2121, and the push rod can push the freeze-dried balls in the cache channel 21211 to move to the unqualified channel 21213. Specifically, the push rod can be a push rod of a push rod motor, or the push rod is an output rod of a cylinder.

[0174] See also Fig. 9 and Fig.11 The freeze-dried ball packaging module 21 also includes a control cabinet 214, which is provided with electrical accessories such as a control circuit board and a solenoid valve for controlling the operating status of the freeze-dried ball dispensing equipment 211 and the freeze-dried ball packaging equipment 212 to achieve electrical automatic control.

[0175] Optionally, see Fig. 20 , Fig.21 and Fig. 22 The freeze-dried ball dispensing module 21 also includes a freeze-dried ball loading device 213, which includes a fixed frame 2131 and a loading bin 2132. The discharge end of the loading bin 2132 can be connected to the storage bin 2111 of the freeze-dried ball dispensing device 211. The loading bin 2132 is swingably arranged on the fixed frame 2131. When the loading bin 2132 swings and tilts at a preset angle relative to the fixed frame 2131, the freeze-dried balls in the loading bin 2132 can fall into the storage bin 2111 through the discharge end of the loading bin 2132. By tilting the loading bin 2132 at a certain angle, the freeze-dried balls can automatically enter the storage bin 2111 of the freeze-dried ball dispensing device 211, so as to realize automatic loading to the freeze-dried ball dispensing device 211 and improve the loading efficiency of the freeze-dried balls. In addition, the loading method of tilting the loading bin 2132 to allow the freeze-dried balls to fall automatically can prevent the freeze-dried balls from being damaged, ensure the quality of the freeze-dried balls after packaging, and improve the product qualification rate.

[0176] See also Fig. 20 and Fig.21, the freeze-dried ball loading device 213 also includes a lifting drive member 2133, the loading bin 2132 includes a first end and a second end that are relatively arranged, the first end is used as a connection end, and the second end is used as a free end. For example, the first end is rotatably connected to the fixed frame 2131, and the lifting drive member 2133 is used to drive the loading bin 2132 to swing up and down relative to the fixed frame 2131, so that the second end can be lifted and lowered relative to the first end. Specifically, when the output end of the lifting drive member 2133 rises, it can exert an upward force on the loading bin 2132. Since the first end of the loading bin 2132 is rotatably connected to the fixed frame 2131, the second end of the loading bin 2132 as a free end can rise relative to the first end, causing the loading bin 2132 to tilt relative to the fixed frame 2131, so that the freeze-dried balls in the loading bin 2132 can roll into the material cutting chamber 21340 under the action of their own gravity. By adjusting the tilt angle of the loading bin 2132 by lifting, the structure is simple, easy to implement, and the lifting drive is stable, which can prevent the freeze-dried balls from breaking to the greatest extent and ensure the quality of the freeze-dried balls after packaging. For example, the lifting drive member 2133 can be a linear drive member such as a cylinder or an electric cylinder.

[0177] The above-mentioned preset angle can be determined according to the actual feeding amount of the freeze-dried balls. For example, if the feeding amount of the freeze-dried balls is large, the lifting height of the lifting drive 2133 can be controlled to be higher, so that the upper bin 2132 is tilted at a larger angle; if the feeding amount of the freeze-dried balls is small, the lifting height of the lifting drive 2133 can be controlled to be smaller, so that the upper bin 2132 is tilted at a smaller angle.

[0178] Optionally, see Fig.21 , a rotatable rolling body 21331 is provided at the output end of the lifting drive member 2133, and the rolling body 21331 rolls with the outer peripheral surface of the upper bin 2132, which can reduce the driving resistance of the lifting drive member 2133 and improve the driving efficiency. Exemplarily, the rolling body 21331 is a roller. In other embodiments, the output end of the lifting drive member 2133 can also be slidably connected to the upper bin 2132. During the lifting and lowering process of the lifting drive member 2133, the output end of the lifting drive member 2133 adaptively slides relative to the upper bin 2132, thereby preventing the upper bin 2132 from interfering with the lifting and lowering of the lifting drive member 2133.

[0179] Optionally, see Fig.21The freeze-dried ball loading device 213 also includes a first elastic member 2137, one end of which is connected to the fixed frame 2131, and the other end is connected to the loading bin 2132. The rolling body 21331 can always contact the outer peripheral surface of the loading bin 2132 under the elastic force of the first elastic member 2137. That is, the first elastic member 2137 is always in an energy storage state, and can apply a pulling force to the loading bin 2132, so that the outer peripheral surface of the loading bin 2132 is always in contact with the rolling body 21331, ensuring that the rolling body 21331 can always roll with the outer peripheral surface of the loading bin 2132 during the lifting process of the lifting drive member 2133, thereby improving the stability of the loading bin 2132 during the tilting process. At the same time, the first elastic member 2137 also has a reset function on the loading bin 2132, so that the loading bin 2132 can move downward and reset to a horizontal position. Specifically, when the lifting drive member 2133 descends, the upper bin 2132 can descend accordingly under the pulling force of the first elastic member 2137, so that the upper bin 2132 is automatically reset. Exemplarily, the first elastic member 2137 is a tension spring.

[0180] Of course, in other embodiments, the first elastic member 2137 may not be provided. For example, the rolling body 21331 at the output end of the lifting drive member 2133 is rollingly matched and connected with the upper bin 2132, or the output end of the lifting drive member 2133 is slidingly connected with the upper bin 2132, and the output end of the lifting drive member 2133 drives the upper bin 2132 to move together when the output end of the lifting drive member 2133 is lifted, so that the upper bin 2132 can be tilted to a preset angle and can also be reset.

[0181] See also Fig.12 , Fig. 20 , Fig.21 and Fig. 22 The freeze-dried ball loading device 213 further includes a material cut-off bin 2134 and a fourth blocking member 2136. The material cut-off bin 2134 is disposed at the discharge end of the upper bin 2132, and has a material cut-off cavity 21340. The fourth blocking member 2136 is movably disposed in the material cut-off bin 2134, and the fourth blocking member 2136 has a third position and a fourth position; in the third position, the fourth blocking member 2136 extends into the material cut-off cavity 21340 and separates the material cut-off cavity 21340 into a first cavity 21340a and a second cavity 21340b that are independent of each other, the first cavity 21340a is used to communicate with the upper bin 2132, and the second cavity 21340b is used to communicate with the storage bin 2111; in the fourth position, the fourth blocking member 2136 moves out of the material cut-off cavity 21340, so that the first cavity 21340a of the material cut-off cavity 21340 can communicate with the storage bin 2111.

[0182] Specifically, before the freeze-dried ball loading 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 loading bin 2132 is not connected to the storage bin 2111. After the freeze-dried ball loading device 213 is activated, the lifting drive member 2133 drives the loading bin 2132 to tilt at a certain angle, and a part of the freeze-dried balls in the loading 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 balls. When the loading bin 2132 is adjusted to a horizontal state again and the fourth blocking member 2136 is switched from the third position to the fourth position, the first chamber 21340a is connected to the second chamber 21340b and the storage bin 2111, and the freeze-dried balls temporarily stored in the first chamber 21340a enter the storage bin 2111 through the second chamber 21340b, completing the quantitative loading of the freeze-dried ball dispensing equipment 211.

[0183] That is, each time the freeze-dried ball loading device 213 operates, it replenishes the freeze-dried ball dispensing device 211 with a certain amount of freeze-dried balls that can be accommodated in the first chamber 21340a, thereby achieving quantitative loading of the freeze-dried ball dispensing device 211, thereby accurately controlling the single loading amount of the freeze-dried balls, preventing the freeze-dried ball dispensing device 211 from getting stuck, ensuring the continuity of the freeze-dried ball packaging production work, and improving the freeze-dried ball packaging efficiency.

[0184] It is understandable that since the freeze-dried balls will temporarily store in the cutting chamber 21340 before entering the storage bin 2111, the volume of the cutting chamber 21340 determines the number of freeze-dried balls entering the storage bin 2111, that is, by setting the cutting chamber 21340, quantitative replenishment of the storage bin 2111 can be achieved.

[0185] Furthermore, the discharge end of the material cutting bin 2134 is connected to the material storage bin 2111 of the freeze-dried ball dispensing device 211 through the material delivery pipe 2135. When the fourth blocking member 2136 moves out of the material cutting chamber 21340, the freeze-dried balls in the material cutting chamber 21340 automatically roll into the material delivery pipe 2135 under the action of their own gravity, and enter the material storage bin 2111 along the material delivery pipe 2135. The material delivery pipe 2135 can guide the freeze-dried balls into the material storage bin 2111, and can ensure that the freeze-dried balls are in a closed environment during the loading process to prevent the freeze-dried balls from being contaminated.

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

[0187] Optionally, see Fig. 22The upper bin 2132 includes an upper bin body 2132a and an upper body 2132b. The upper bin body 2132a is provided with an installation cavity, and the upper body 2132b is embedded in the installation cavity. The upper body 2132b has a hollow inner cavity, and the cross-sectional area of ​​the hollow inner cavity gradually decreases in the direction close to the discharge end. That is, the inner cavity of the upper body 2132b is funnel-shaped. When the upper bin 2132 is tilted, the freeze-dried balls in the upper body 2132b are more likely to automatically gather in the material cutting cavity 21340 under the action of their own gravity, which can improve the ball falling efficiency. In addition, the above design method makes it possible for the freeze-dried balls in the upper body 2132b to flow to the material cutting cavity 21340 only when the upper bin 2132 is tilted, and the freeze-dried balls will not flow out when the upper bin 2132 is horizontal and not tilted. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space where the hollow inner cavity of the upper material body 2132b is located, rather than the cross-sectional area of ​​the upper material body 2132b.

[0188] In addition, the split structural design of the loading bin 2132 can also replace the loading body 2132b of suitable volume according to actual needs. That is, a plurality of loading bodies 2132b with different volumes can be manufactured, and the loading body 2132b of the currently required volume can be replaced as needed without replacing the entire loading bin 2132 as a whole. This is convenient, fast and more cost-effective.

[0189] Optionally, see Fig. 22 The material-cutting bin 2134 includes a material-cutting bin body 2134a and a quantitative member 2134b. The material-cutting bin body 2134a is provided with the above-mentioned material-cutting chamber 21340. The quantitative member 2134b is installed in the first chamber 21340a of the material-cutting chamber 21340. The quantitative member 2134b has an inner cavity, and the inner cavity has an inlet and an outlet. The inlet is communicated with the loading bin 2132. When the fourth blocking member 2136 is in the third position, the outlet is blocked so that a certain amount of freeze-dried balls are temporarily stored in the inner cavity of the quantitative member 2134b. The material-cutting bin 2134 is designed as a split structure, and the quantitative member 2134b can be replaced separately to change the single loading amount of the freeze-dried balls. Specifically, the quantitative member 2134b is detachably installed in the first chamber 21340a, and the quantitative member 2134b is provided with a plurality of quantitative members 2134b, and the volumes of the inner cavities of the plurality of quantitative members 2134b are different. The single loading amount of the freeze-dried ball can be changed by using quantitative pieces 2134b of different volumes, thereby expanding the application scope of the freeze-dried ball loading equipment.

[0190] Optionally, the cross-sectional area of ​​the inner cavity of the quantitative member 2134b gradually increases from the inlet to the outlet. That is, the inner cavity of the quantitative member 2134b is funnel-shaped, and its inner wall surface is tilted downward relative to the discharge end of the upper bin 2132, so that the freeze-dried balls in the upper bin 2132 can automatically roll into the quantitative member 2134b, and the freeze-dried balls can be temporarily stored in the quantitative member 2134b without flowing back to the upper bin 2132. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space where the inner cavity of the quantitative member 2134b is located, rather than the cross-sectional area of ​​the quantitative member 2134b.

[0191] Optionally, the cut-off bin 2134 is provided with a fourth blowing device 2139 (such as Fig. 22 As shown in the figure, the air outlet end of the fourth blowing device 2139 is connected to the material cutting chamber 21340 and is located at a position of the material cutting chamber 21340 near the discharge end of the upper bin 2132, and is used to blow the freeze-dried balls in the material cutting chamber 21340 into the storage bin 2111. Blowing through the fourth blowing device 2139 can assist in delivering the freeze-dried balls in the quantitative member 2134b in the material cutting chamber 21340 into the feeding pipe 2135, so that the freeze-dried balls can enter the storage bin 2111 of the freeze-dried ball dispensing device 211 more smoothly, thereby improving the feeding efficiency. Since the air outlet end of the fourth blowing device 2139 is at one end of the material cutting chamber 21340 near the upper bin 2132, the freeze-dried balls can be further prevented from flowing back to the upper bin 2132. Exemplarily, the fourth blowing device 2139 can be an air pump, etc., as long as it can generate a stable airflow.

[0192] See also Fig. 20 and Fig. 22 The upper bin 2132 has a feed port 21320, and a feed hopper 2138 is provided at the feed port 21320. The feed hopper 2138 has a guide slope for guiding the freeze-dried balls to the feed port 21320. The provision of the feed hopper 2138 can expand the feeding space, which is more conducive to adding freeze-dried balls to the upper bin 2132, improving the efficiency of loading freeze-dried balls, and preventing the freeze-dried balls from falling to the outside. For details, see Fig. 22 The guide slope is tilted downward in the direction close to the feed port 21320.

[0193] Optionally, see Fig. 9 , Fig.23 and Fig.24 The first conveyor line body 22 and the second conveyor line body 23 each include a base body 221, a conveying device 222 and a protective device 223. The conveying device 222 includes a conveyor belt 2221 drivably disposed on the base body 221, and the carrier 10 carrying the reaction disk is placed on the conveyor belt 2221. The protective device 223 is disposed on the base body 221, and defines a closed conveying space 224 on the base body 221, and the conveying device 222 is located in the conveying space 224.

[0194] It can be understood that the above-mentioned closed conveying space 224 has an entrance and an exit. The carrier 10 carrying the reaction disk enters from the entrance of the conveying space 224 and is placed on the conveyor belt 2221. After the ball planting of the reaction disk is completed, the conveyor belt 2221 then conveys the carrier 10 to the exit of the conveying space 224, so that the carrier 10 carrying the reaction disk enters the next process.

[0195] By setting a protective device 223 on the base 221 and arranging the conveying device 222 in the conveying space 224, when the carrier 10 carries the reaction disk and flows on the conveyor belt 2221 of the conveying device 222, the reaction disk is always in a relatively closed conveying space 224, which can prevent dust from falling on the reaction disk and other objects from falling on the reaction disk, prevent the freeze-dried balls on the reaction disk from contacting 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 driving mechanism (not shown) and a transmission wheel 2222, the conveyor belt 2221 is wound around the transmission wheel 2222, and the output end of the driving mechanism is in transmission connection with the transmission wheel 2222, for driving the transmission wheel 2222 to rotate and drive the conveyor belt 2221 to transmit, thereby transporting the carrier 10. Exemplarily, the driving mechanism is a rotary motor.

[0197] See also Fig.23 and Fig.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 arranged on both sides of the conveying device 222 in the width direction. The cover plate 2233 is located above the conveying device 222, one end of which is connected to the first protective plate 2231, and the other end is connected to the second protective plate 2232. The cover plate 2233 and the first protective plate 2231 and the second protective plate 2232 are surrounded to form a conveying space 224. The first protective plate 2231, the second protective plate 2232 and the cover plate 2233 cooperate to cover the carrier 10 carrying the reaction disk on the conveyor belt 2221, so that the reaction disk on the carrier 10 is isolated from the outside, and the freeze-dried balls on the reaction disk are prevented from being contaminated. The width direction of the conveying device 222 is a direction 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, and a conveyor belt 2221 is provided on the first mounting plate 2211 and the second mounting plate 2212 facing each other, and 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 is placed on one row of conveyor belts 2221, and the other side of the carrier 10 is placed on the other row of conveyor belts 2221, so that the flow of the carrier 10 is more stable. The setting of the first mounting plate 2211 and the second mounting plate 2212 provides a mounting basis 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 to cover the conveying device 222 .

[0199] See also Fig.23 and Fig.24 , and combined with Figure 3 , the cover plate 2233 of the protective device 223 is provided with an installation space directly facing the ball planting station 24, and the freeze-dried ball guide device 220 is installed in the installation space, and the freeze-dried ball guide device 220 is used to fit with the reaction disk on the carrier 10. That is, the cover plate 2233 also provides an installation base for the freeze-dried ball guide device 220, so that the freeze-dried ball guide device 220 can be suspended above the ball planting station 24, which does not interfere with the carrier 10 carrying the reaction disk on the conveyor belt 2221, and enables the freeze-dried ball packaging device 212 to plant the freeze-dried balls to the ball planting holes of the reaction disk through the freeze-dried ball guide device 220.

[0200] See also Fig.25The freeze-dried ball guiding device 220 includes a fixed support 2201, a guide disk 2202 and a plug-in disk 2203. The fixed support 2201 is configured to be connected to the cover plate 2233. The guide disk 2202 is arranged on the fixed support 2201. The plug-in disk 2203 is stacked on the side of the guide disk 2202 facing away from the reaction disk. The plug-in disk 2203 is used to fit with the reaction disk, wherein a plurality of guide holes are arranged on the guide disk 2202, and a plug-in hole connected to the plurality of guide holes in a one-to-one correspondence is arranged on the plug-in disk 2203. The reaction disk to be planted with balls has a plurality of ball planting hole positions. After the reaction disk is fitted with the plug-in disk 2203, the plurality of plug-in holes, the plurality of guide holes and the plurality of ball planting hole positions are connected in a one-to-one correspondence. The discharge nozzle of the freeze-dried ball packaging device 212 is inserted into the corresponding plug-in hole so that the freeze-dried balls can accurately fall from the guide holes into the corresponding ball planting hole positions. The guide hole can guide the freeze-dried balls to fall accurately into the corresponding ball planting holes, preventing the freeze-dried balls from rolling off the reaction plate and breaking and losing powder. During the ball planting process, the freeze-dried balls will not come into contact with foreign objects, which can prevent the freeze-dried balls from being contaminated. The setting of the plug hole can accurately align the discharge nozzle with the guide hole, improving the efficiency of freeze-dried ball packaging.

[0201] See also Fig.25 A supporting portion 22011 is protrudingly provided on the fixed support 2201, and a connecting portion 22021 is protrudingly provided on the edge of the guide plate 2202. The connecting portion 22021 is mounted on the supporting portion 22011 and fixedly connected to the supporting portion 22011, so that there is 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 conveying line body 22 and the second conveying line body 23 have the same structure. Fig.24 The first conveyor line 22 also includes a lifting device 225 disposed at the freeze-dried ball docking station, and the lifting device 225 is used to lift the carrier 10 delivered to the ball planting station 24 until the reaction plate on the carrier 10 is fitted with the freeze-dried ball guide device 220, and then the discharge nozzle of the freeze-dried ball dispensing device 212 is inserted into the plug hole of the plug-in 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 setting of the lifting device 225 can selectively fit or separate the reaction plate on the carrier 10 and the freeze-dried ball guide device 220, thereby completing the transportation of the reaction plate and the dispensing of the freeze-dried balls in the reaction plate.

[0203] See also Fig.24The base 221 is provided with a limiter 2213, which is used to limit the travel of the lifting device 225 lifting the carrier 10. When the lifting device 225 lifts the carrier 10 to contact with the limiter 2213, the carrier 10 can no longer move upward, which can prevent the carrier 10 from moving upward beyond the travel, avoid the reaction disk and the freeze-dried ball guide device 220 from hard contact, and protect the reaction disk and the freeze-dried ball guide device 220.

[0204] Exemplarily, the lifting device 225 may include a cylinder and a lifting plate arranged at the output end of the cylinder. The cylinder drives the lifting plate to rise until it contacts the carrier 10, and lifts the carrier 10 until the reaction plate on the carrier 10 is in contact with the freeze-dried ball guide device 220.

[0205] See also Fig.24 The first conveyor line body 22 further includes a blocking device 226, which is located downstream of the ball planting station 24 and is used to limit the carrier 10 on the conveyor belt 2221 to stop at the ball planting station 24, and can prevent the carrier 10 from moving over the conveyor belt 2221, ensuring that the lifting device 225 can accurately align with the carrier 10, and ensuring that the reaction plate on the carrier 10 can face the freeze-dried ball guide device 220. Exemplarily, the blocking device 226 may include a cylinder and a blocking block disposed at the output end of the cylinder, and the cylinder drives the blocking block to rise and fall to block the carrier 10 or avoid the carrier 10.

[0206] See also Fig.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. The positioning platform 1011 is used to place the reaction disk 20. The clamping device 102 includes a first clamping jaw 1021 and a second clamping jaw 1022 movably provided on the carrier body 101. The first clamping jaw 1021 and the second clamping jaw 1022 are distributed on opposite sides of the positioning platform 1011. The first clamping jaw 1021 and the second clamping jaw 1022 have a tendency to move toward each other so as to clamp and fix the reaction disk 20, and the first clamping jaw 1021 and the second clamping jaw 1022 can move in a direction away from each other under the action of an external force to release the reaction disk 20. The positioning platform 1011 cooperates with the first clamping jaw 1021 and the second clamping jaw 1022 to firmly limit the reaction disk 20 on the carrier body 101.

[0207] Specifically, a first positioning column is provided at the center of the positioning platform 1011, and a first positioning hole is provided at the center of the reaction disk. After the first positioning column is plugged into the first positioning hole, it can be ensured that the reaction disk is stacked directly above the positioning platform 1011. The positioning platform 1011 is provided with a second positioning column offset from the center, and the reaction disk is correspondingly provided with a second positioning hole. The second positioning column is plugged into the second positioning hole to position the reaction disk relative to the positioning platform 1011 in the circumferential direction, ensuring that the positions of the multiple ball planting holes on the reaction disk are correct, and at the same time, the placement stability of the reaction disk on the positioning platform 1011 can be further improved.

[0208] See also Fig.26 The clamping device 102 further includes a driving jaw 1023 movably disposed on the carrier body 101 along a preset direction, and a push structure is disposed on the side of the first jaw 1021 and the second jaw 1022 facing each other, and the driving jaw 1023 is at least partially located between the two push structures. When the driving jaw 1023 moves along the preset direction, it can slide and cooperate with the two push structures to drive the first jaw 1021 and the second jaw 1022 to move in a direction away from each other. That is, the driving jaw 1023 can simultaneously apply an external force to the first jaw 1021 and the second jaw 1022, so that the first jaw 1021 and the second jaw 1022 move synchronously in a direction away from each other.

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