Description

Technical Field

[0001] This application relates to the technical field of filling equipment, and in particular to a multi-chamber reagent kit filling device. Background Technology

[0002] In fields such as medical testing and biological experiments, multi-compartment reagent kits serve as carriers for precise reactions or storage of reagents. They often require separate compartments to store reagents with different properties or reagents for stepwise reactions. The filling process of multi-compartment reagent kits must ensure the accurate filling of reagents in each compartment, while also adapting to large-scale production to reduce unit costs.

[0003] In the current mainstream multi-chamber reagent kit filling process, the reagent kit is moved to the filling station via a conveyor system, with the corresponding chamber positioned directly below the filling head. Subsequently, the filling head moves down, and its liquid outlet is inserted into the target chamber. The reagent filling is completed through an independent liquid supply pipeline. After the filling operation is completed, the filling head returns to its initial height, and the filled reagent kit is moved out of the filling station. At the same time, the next batch of reagent kits to be filled moves to the filling station.

[0004] Regarding the aforementioned technologies, during the filling process of multi-compartment reagent kits, the high-speed flow of reagents impacting the inner walls of the compartments can easily cause reagent splashing. Due to the lack of an isolation mechanism, these unblocked reagent droplets can directly invade adjacent compartments, causing reagent contamination. Therefore, there is an urgent need to design a structure that can accurately align with the target compartment while reliably sealing off non-filling compartments, thereby eliminating the risk of cross-contamination through structural design and improving filling efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a multi-chamber reagent kit filling device.

[0006] This application provides a multi-chamber reagent kit filling device, which adopts the following technical solution:

[0007] A multi-compartment reagent kit filling device includes a frame, a drive assembly, a transmission assembly, a base assembly, a shielding assembly, and a filling assembly. The drive assembly is mounted on the frame and is drivenly connected to the transmission assembly. One end of the base assembly is connected to the transmission assembly, and the transmission assembly drives the base assembly to move vertically. The shielding assembly and the filling assembly are mounted on the base assembly. The end of the filling assembly used for dispensing liquid corresponds to the target compartment of the multi-compartment reagent kit, and the end of the shielding assembly used for shielding corresponds to the non-filling compartment of the multi-compartment reagent kit.

[0008] By adopting the above technical solution, one end of the base assembly is connected to the transmission assembly, enabling the base assembly to move up and down in the vertical direction. The filling assembly and the shielding assembly are installed on the base assembly, which further drives the shielding assembly and the filling assembly to move synchronously, ensuring that the ends of the two are precisely aligned with the target chamber and non-filling chamber of the reagent kit, thus achieving accurate reagent injection. The shielding end of the shielding assembly simultaneously covers the non-filling chamber, effectively preventing reagents from splashing into the non-filling chamber during the filling process, and structurally avoiding the problem of cross-contamination during multi-chamber filling.

[0009] Preferably, the base assembly includes a fixing rod, a first mounting plate, and a second mounting plate. The first mounting plate is connected to the transmission assembly. One end of the fixing rod is fixed in the first mounting plate. The second mounting plate is connected to the fixing rod at a position away from the first mounting plate. The shielding assembly and the filling assembly are mounted on the second mounting plate.

[0010] By adopting the above technical solution, the transmission connection between the first mounting plate and the transmission assembly provides a vertical moving base for the fixed rod, enabling the fixed rod to drive the second mounting plate and the associated filling and shielding components to move vertically under the drive of the transmission assembly. This ensures that the ends of the filling and shielding components are aligned with the target chamber and non-filling chamber of the multi-chamber reagent kit with high precision, while one end of the fixed rod is embedded in the first mounting plate to form a stable support.

[0011] Preferably, the second mounting plate includes a connecting part and a mounting part, the connecting part and the mounting part are fixed together, the connecting part is sleeved on the fixing rod, the mounting part has a plurality of positioning holes, the mounting part has an installation opening on the side corresponding to the positioning holes, the positioning holes on the mounting part are connected to the installation opening, and the positioning holes of the mounting part are respectively used to install the filling component and the shielding component.

[0012] By adopting the above technical solution, the connection structure between the positioning hole and the mounting port on the second mounting plate provides a way to position and install the shielding component and the filling component. This ensures that the filling component and the shielding component are positioned on the mounting part, so that the liquid outlet end of the filling component and the shielding end of the shielding component can accurately correspond to the target chamber and non-filling chamber of the multi-chamber reagent kit. This avoids reagent injection failure or shielding failure due to installation deviation. At the same time, the mounting port provides operating space for the installation and disassembly of the filling component and the shielding component, allowing the filling component and the shielding component to pass through the mounting port from the side and top and cooperate with the positioning hole. This simplifies the component installation process and allows replacement without completely disassembling other parts.

[0013] Preferably, a second fastening bolt is provided at a position opposite to the mounting opening of the mounting part. The second fastening bolt passes through the mounting part and abuts against the shielding component or the filling component.

[0014] By adopting the above technical solution, the second fastening bolt passes through the mounting part and directly abuts against the shielding component or filling component. The positioning hole and mounting port on the front of the component are used for guidance and initial positioning by applying pressure from the back, while the second fastening bolt on the back is fixed by tightening.

[0015] Preferably, the shielding assembly includes a movable rod, a shielding block, a first abutting ring, and a first buffer pad. The shielding block is fixedly connected to the bottom end of the movable rod, the first abutting ring is slidably sleeved on the movable rod and embedded in the positioning hole, and the first buffer pad is installed at the top end of the movable rod.

[0016] By adopting the above technical solution, the blocking block at the bottom of the movable rod can move up and down with the movable rod to adapt to the chambers of multi-chamber reagent kits of different depths, ensuring that the blocking end can completely cover the adjacent area outside the target chamber. The first abutment ring is slidably assembled on the movable rod and embedded in the positioning hole, allowing the movable rod to slide in the vertical direction. The first buffer pad can reduce the rigid collision between the movable rod and the mounting part, avoid the wear of the positioning hole edge caused by long-term impact, and extend the service life of the component.

[0017] Preferably, the outer wall of the first abutment ring is provided with a first annular groove along the circumferential direction, and the second fastening bolt abuts against the first annular groove.

[0018] By adopting the above technical solution, the first annular groove and the end of the second fastening bolt are precisely matched to prevent slippage or displacement during the contact process.

[0019] Preferably, a second abutment ring is fixedly installed at a position away from the liquid outlet of the filling assembly. The second abutment ring is embedded in the positioning hole. A second annular groove is formed on the outer side wall of the second abutment ring in the circumferential direction. The second fastening bolt abuts against the second annular groove.

[0020] By adopting the above technical solution, the cooperation between the second annular groove and the second fastening bolt prevents the filling component from sliding during the contact process. At the same time, the second contact ring is fixedly connected to the filling component, preventing the filling component from sliding off the base component.

[0021] Preferably, the transmission assembly includes a synchronous pulley, a synchronous belt, and a lead screw. The first mounting plate is threadedly connected to the lead screw, the top of the lead screw is rotatably mounted on the frame, the bottom of the lead screw is connected to the synchronous pulley, the output shaft of the drive assembly is provided with a drive pulley, and the synchronous belt is sleeved on the synchronous pulley and the drive pulley.

[0022] By adopting the above technical solution, the power transmission from the drive component to the transmission component is ensured, enabling the first mounting plate to move in the vertical direction. This meets the lifting and lowering requirements of the base component during the filling of multi-chamber reagent kits, and avoids the situation where the reagent cannot be inserted into the target chamber during filling, resulting in filling failure.

[0023] Preferably, a second buffer pad is installed on the frame, and the second buffer pad is located directly below the first mounting plate.

[0024] By adopting the above technical solution, the second buffer pad can absorb the inertial impact force through compression deformation when the first mounting plate moves downward to near the bottom frame, thereby preventing the first mounting plate from rigidly colliding with the frame and protecting the first mounting plate and the frame from damage, thus extending the service life of the components.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. One end of the base assembly is connected to the transmission assembly, enabling the base assembly to move vertically up and down. The filling assembly and the shielding assembly are mounted on the base assembly, further driving the synchronous movement of the shielding assembly and the filling assembly. This ensures that the ends of both are precisely aligned with the target chamber and the non-filling chamber of the reagent kit, achieving accurate reagent injection. The shielding end of the shielding assembly simultaneously covers the non-filling chamber, effectively preventing reagents from splashing into the non-filling chamber during the filling process. Structurally, this avoids the problem of cross-contamination during multi-chamber filling.

[0027] 2. The transmission connection between the first mounting plate and the transmission assembly provides a vertical moving base for the fixed rod, enabling the fixed rod to drive the second mounting plate and the associated filling and shielding components to move vertically under the drive of the transmission assembly. This ensures that the ends of the filling and shielding components are aligned with the target chamber and non-filling chamber of the multi-chamber kit with high precision, while one end of the fixed rod is embedded in the first mounting plate to form a stable support.

[0028] 3. The connection structure between the positioning hole and the mounting port on the second mounting plate provides a positioning and installation method for the shielding component and the filling component. This ensures that the filling component and the shielding component are positioned correctly on the mounting part, so that the liquid outlet end of the filling component and the shielding end of the shielding component can accurately correspond to the target chamber and non-filling chamber of the multi-chamber reagent kit. This avoids reagent injection failure or shielding failure due to installation deviation. At the same time, the mounting port provides operating space for the installation and disassembly of the filling component and the shielding component. It allows the filling component and the shielding component to pass through the mounting port from the side and the top and mate with the positioning hole, simplifying the component installation process and allowing replacement without completely disassembling other parts.

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0036] This application discloses a multi-chamber reagent kit filling device.

[0037] Reference Figure 1 A multi-chamber reagent kit filling device includes a frame 1, a drive assembly 2, a transmission assembly 3, a base assembly 4, a shielding assembly 5, and a filling assembly 6. The drive assembly 2 is mounted on the bottom of the frame 1, and the output shaft of the drive assembly 2 is connected to the transmission assembly 3. One end of the base assembly 4 is connected to the transmission assembly 3, and the transmission assembly 3 drives the base assembly 4 to move up and down in the vertical direction. The shielding assembly 5 and the filling assembly 6 are installed on the base assembly 4. The multi-chamber reagent kit is located directly below the shielding assembly 5 and the filling assembly 6, and the end of the filling assembly 6 used for dispensing liquid corresponds to the target chamber of the multi-chamber reagent kit, while the end of the shielding assembly 5 used for shielding corresponds to the non-filling chamber of the multi-chamber reagent kit.

[0038] During the filling of the multi-compartment reagent kit, the drive assembly 2 drives forward, and the base assembly 4 moves downward under the action of the transmission assembly 3. The shielding assembly 5 and the filling assembly 6 located on the base assembly 4 move downward synchronously. When the shielding assembly 5 and the filling assembly 6 reach the multi-compartment reagent kit, the filling assembly 6 continues to move downward to the target chamber of the multi-compartment reagent kit, and the shielding assembly 5 abuts against the inlet of the non-filling chamber, sealing the non-filling chamber of the multi-compartment reagent kit. At this time, the reagent is injected into the target chamber through the filling assembly 6. After the reagent injection is completed, the drive assembly 2 drives in reverse, and the transmission assembly 3 drives the base assembly 4 to move to the initial position before the filling operation.

[0039] In this preferred embodiment, when the filling component 6 moves to its lowest position and begins injecting reagent into the target chamber, the drive component 2 reverses its direction, and the transmission component 3 drives the base component 4 to gradually move away from the reagent kit. The filling component 6 remains directly above the reagent surface without contacting the reagent, while maintaining a very close distance between the outlet and the liquid surface to reduce reagent impact and splashing. This achieves the function of filling while resetting, until the reagent injection is complete. After the injection operation is finished, the drive component 2 continues to reverse its direction, moving the base component 4 back to its initial position before the filling operation.

[0040] Reference Figure 1 and Figure 2 The base assembly 4 includes a fixing rod 401, a first mounting plate 402, and a second mounting plate 403. The first mounting plate 402 is connected to the transmission assembly 3. One end of the fixing rod 401 is embedded in the first mounting plate 402. A first fastening bolt 7 is provided on the side of the first mounting plate 402. The first fastening bolt 7 is screwed into the side of the mounting plate and clamps and fixes the fixing rod 401. The second mounting plate 403 is connected to the fixing rod 401 at a position away from the first mounting plate 402. The shielding assembly 5 and the filling assembly 6 are mounted on the second mounting plate 403. Further, two fixing ports 8 are opened at the end of the fixing rod 401 near the second mounting plate 403. The external liquid outlet pipe passes through the fixing ports 8 and is connected to the filling assembly 6.

[0041] Specifically, refer to Figure 3 The second mounting plate 403 includes a connecting part 15 and a mounting part 9. The mounting part 9 is fixed to the connecting part 15. The connecting part 15 is sleeved on the fixing rod 401. The mounting part 9 has a plurality of positioning holes 10 for mounting the shielding component 5 or the filling component 6. The position of the positioning holes 10 corresponds to the chamber of the multi-chamber reagent kit.

[0042] Furthermore, the mounting part 9 has a mounting opening 11 on its side corresponding to the positioning hole 10. The positioning hole 10 on the mounting part 9 is connected to the mounting opening 11, and the diameter of the positioning hole 10 is larger than the opening spacing of the mounting opening 11. The shielding assembly 5 and the filling assembly 6 can be installed in the corresponding positioning hole 10 according to the position of the target chamber and the non-filling chamber of the multi-chamber reagent kit.

[0043] In this embodiment, two mounting portions 9 are provided, forming a U-shape with the connecting portion 15. Each mounting portion 9 has three positioning holes 10. On the inner side of the two mounting portions 9 facing each other, corresponding to the positions of the positioning holes 10, a mounting opening 11 is provided on each. A filling component 6 is installed in one positioning hole 10 of each mounting portion 9 away from the connecting portion 15, and a shielding component 5 is installed in the remaining positioning holes 10.

[0044] The mounting part 9 is provided with a second fastening bolt 12 at a position opposite to the mounting port 11. The second fastening bolt 12 passes through the mounting part 9 and abuts against the shielding component 5 or the filling component 6.

[0045] Reference Figure 4 The shielding component 5 includes a movable rod 501, a shielding block 502, a first abutting ring 503, and a first buffer pad 504. The shielding block 502 is fixedly connected to the bottom end of the movable rod 501. The first abutting ring 503 is slidably sleeved on the movable rod 501 and embedded in the positioning hole 10. The first buffer pad 504 is installed on the top end of the movable rod 501.

[0046] Furthermore, a first annular groove 13 is provided on the outer side wall of the first abutting ring 503 in the circumferential direction, and one end of the second fastening bolt 12 extends into the first annular groove 13 and abuts against the bottom of the groove, making the abutting structure more secure.

[0047] Furthermore, the first buffer pad 504 is made of polyurethane. The polyurethane first buffer pad 504 ensures that the movable rod 501 will not fall off. At the same time, when the first buffer pad 504 comes into contact with the first abutment ring 503, it can buffer the impact generated during the contact.

[0048] A second abutment ring 16 is fixedly installed on the filling assembly 6 at a position away from the liquid outlet. Similarly, the second abutment ring 16 is embedded in the positioning hole 10. A second annular groove 14 is provided on the outer side wall of the second abutment ring 16 in the circumferential direction. One end of the second fastening bolt 12 extends into the second annular groove 14 and abuts against the bottom of the groove, ensuring that the structure of the second fastening bolt 12 abutting against the filling assembly 6 is more secure.

[0049] When no filling operation is being performed, the blocking block 502 and the movable rod 501 slide downwards under their own weight, causing the blocking block 502 to move away from the first abutment ring 503. When the filling operation is being performed, as the base assembly 4 moves to the multi-chamber reagent kit, the filling assembly 6 fixed on the base assembly 4 continues to move downwards to the target chamber, and the blocking block 502 abuts against the entrance of the non-filling chamber and completely blocks it, while stopping its movement. At this time, the movable rod 501 and the first abutment ring 503 slide together. As the base assembly 4 continues to move downwards, the first abutment ring 503 moves downwards synchronously along the movable rod 501, while the movable rod 501 and the blocking block 502 remain stationary.

[0050] Furthermore, after the injection operation is completed, the base assembly 4 gradually rises, and the first abutment ring 503 rises synchronously along the movable rod 501. The movable rod 501 and the first abutment ring 503 slide relative to each other until the first abutment ring 503 contacts the first buffer pad 504, so that the movable rod 501 and the first abutment ring 503 stop sliding and remain relatively stationary. The base assembly 4 continues to move upward, and the movable rod 501 and the first abutment ring 503 rise synchronously with the base assembly 4.

[0051] Reference Figure 5 The transmission assembly 3 includes a synchronous pulley 301, a synchronous belt 302, and a lead screw 303. The first mounting plate 402 is threaded onto the lead screw 303, and the axis of the fixing rod 401 is parallel to the axis of the lead screw 303. The top of the lead screw 303 is rotatably mounted on the top of the frame 1, and the bottom of the lead screw 303 passes through the bottom of the frame 1 and is coaxially connected with the synchronous pulley 301 to ensure that the two rotate coaxially. The synchronous belt 302 is sleeved on the synchronous pulley 301 and the output shaft of the drive assembly 2. Specifically, the drive assembly 2 adopts a servo motor, and its output shaft is provided with a drive pulley 17. The synchronous belt 302 is sleeved on the synchronous pulley 301 and the drive pulley 17 to realize the power transmission of the servo motor.

[0052] Furthermore, a second buffer pad 18 is installed on the frame 1. The second buffer pad 18 is located directly below the first mounting plate 402. When the first mounting plate 402 moves under the transmission of the lead screw 303, the second buffer pad 18 can effectively buffer the impact of the first mounting plate 402 on the frame 1.

[0053] Preferably, the second buffer pad 18 is made of polyurethane. When the polyurethane buffer pad is subjected to pressure, it can quickly absorb the impact force and prevent the first mounting plate 402 from having a rigid collision with the frame 1.

[0054] The implementation principle of this application embodiment is as follows: During the use of the multi-chamber reagent kit filling device, the chambers that need to be filled and sealed for the multi-chamber reagent kit are first determined. Then, the movable rods 501 of multiple shielding components 5 are passed through the corresponding mounting ports 11, and the first abutment ring 503 is slid to place the first abutment ring 503 in the positioning hole 10. The first buffer pad 504 is installed on the top of the movable rods 501. At the same time, one end of the liquid outlet of multiple filling components 6 is passed through the corresponding mounting ports 11, and the filling components 6 are moved so that the second abutment ring 16 is placed in the positioning hole 10. The second fastening bolt 12 is screwed into the mounting part 9 to abut against the annular grooves of the shielding components 5 and the filling components 6 for fixation. Next, the servo motor drives the synchronous pulley 301 to rotate the lead screw 303 in the forward direction. The first mounting plate 402 moves down along the lead screw 303. The second buffer pad 18 absorbs the impact when the first mounting plate 402 moves down. The base assembly 4 carries the shielding components 5 and the filling components 6 down synchronously. When the bottom end of the filling component 6 is inserted into the target chamber of the reagent kit, the blocking block 502 of the blocking component 5 abuts against the inlet of the non-filling chamber and blocks the non-filling chamber; at this time, filling begins, and the reagent is injected into the target chamber through the outlet pipe. During the injection process, the servo motor switches to reverse drive, and the lead screw 303 drives the base component 4 to rise slowly. The filling component 6 moves upward accordingly but always remains above the liquid surface, realizing simultaneous resetting and filling. After the injection is completed, the base component 4 continues to rise to the initial position, and the first abutting ring 503 of the blocking component 5 moves upward with the base component 4, while sliding relative to the movable rod 501 until the first buffer pad 504 contacts the mounting part 9 to buffer the impact caused by the collision during resetting.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
