Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a foam material filling device and filling method, and a storage container preparation method. Background Art

[0002] In the medical device field, specialized storage devices are often required for samples, reagents, and other liquids, due to their specific storage requirements. For example, in immunoassay analyzers, reagents are stored in a corresponding reagent pot, which must have both refrigeration and insulation properties to ensure effective storage of the reagents.

[0003] The existing reagent pot is mostly insulated by sticking insulation cotton. However, the irregular shape of the reagent pot may easily lead to loose adhesion between the reagent pot and the insulation material, and the uneven surface of the shape cannot be completely filled. When a gap is generated between the insulation material and the surface, air will enter the gap during the cooling process of the refrigeration component of the reagent pot and produce condensation water. The condensation water will then seep out, which will lead to the loss of cooling capacity and affect the insulation effect. In addition, the seepage of condensation water may also affect the performance and life of the equipment. Summary of the Invention

[0012] In the device provided by the present invention, after a storage container with a temperature control component is placed on a filling station, a first movable component causes the lid assembly to seal the storage container on the filling station, forming an internal filling space.

[0055] The foaming material filling device according to the first aspect of the present invention will be described in detail below through the accompanying drawings and specific embodiments.

[0056] First, the storage container 100 to be filled by the foam material filling device will be described.

[0057] See Figure 4The storage container 100 includes a container body 110 and a temperature control component 120. The container body 110 is provided with a container body 110 for storing liquids such as reagents. The temperature control component 120 includes a temperature control channel 121 provided on the outside of the container body 110 and connected to the cavity in the container body 110, and a temperature adjustment component 122 provided on the temperature control channel 121. The temperature adjustment component 122 can be provided as a refrigeration component such as a condenser, forming condensed gas circulating in the temperature control channel 121, and entering the cavity or being provided around the outside of the cavity, thereby providing a cooling effect for the cavity. The temperature adjustment component 122 can also be provided as a heating component such as a heating resistor, generating heat by electric heating, and transmitting the hot gas carrying heat to the cavity through the temperature control channel 121 or circulating around the outside of the cavity, thereby providing a heating effect for the cavity. Of course, a refrigeration component and a heating component can also be provided at the same time to achieve both cooling and heating functions.

[0058] In view of the structure of the storage container 100, the junction between the container body 110 and the temperature control member 120 may have uneven areas, particularly the junction between the temperature control channel 121 and the container body 110, which forms a concave structure. Therefore, using the conventional method of attaching thermal insulation foam will form gaps in these uneven areas. The storage container 100 cannot ensure that the thermal insulation material accurately fills the uneven areas. As a result, when the cooling effect is generated, condensed water will condense on the outer wall of the storage container 100 corresponding to the gaps.

[0059] Based on this, the present invention provides a foam material filling device, including a bracket 200, a first moving member 300, a second moving member 400, a pushing assembly 500 and a cover assembly 600, the bracket 200 is provided with a filling station 210 and a guide member, the filling station 210 is located in the guide direction of the guide member ( Figure 5 or Figure 6 The components guided by the guide station can be accurately moved to the filling station 210 (in the first direction in the figure). The filling station 210 has a positioning member 240 for positioning the storage container 100 on the filling station 210. The first and second moving members 300 and 400 are disposed on the support 200. The push assembly 500 is connected to the support 200 via the first moving member 300 and can be driven by the first moving member 300 and guided by the guide member to move in the first direction to the filling station 210. The cover assembly 600 is connected to the support 200 via the second moving member 400 and can be driven by the second moving member 400 and guided by the guide member to move in the first direction to the filling station 210. The cover assembly 600 has a cover space that is recessed in a direction opposite to the first direction. The inner contour of the cover space is larger than the outer contour of the storage container 100, thereby forming a filling space between the cover space and the storage container 100.

[0060] <fill space>

[0061] See Figure 4 and Figure 7 Since the storage container 100 is composed of two parts, the container body 110 and the temperature control component 120, a first area for filling the container body 110 and a second area for filling the temperature control component 120 are formed according to the composition of the two parts. In the actual application of the storage container 100, the thermal insulation requirement of the temperature control component 120 for adjusting the temperature is higher than the thermal insulation requirement of the container body 110 for storing liquid. Based on this, the filling space is divided into a first filling space 660 and a second filling space 670 according to the first area and the second area. The first filling space 660 is formed between the inner wall of the cover assembly 600 and the outer wall of the container body 110, and the second filling space 670 is formed between the inner wall of the cover assembly 600 and the outer wall of the temperature control component 120. The filling thickness of the first filling space 660 is smaller than the filling thickness of the second filling space 670, so that when filling, there is more foam material on the outer wall of the temperature control component 120 as an insulation layer, while the thickness of the foam material outside the container body 110 is relatively thin, and the insulation effect is relatively low. Moreover, when the temperature control component 120 is performing a cooling operation, the temperature in the temperature control channel 121 is lower than that in the inner cavity of the container body 110. The thick insulation layer has a stronger heat resistance than the thin insulation layer of the container body 110, and is less likely to dissipate heat outward, so that the cooling air of the temperature control component 120 is better transmitted to the container body 110, thereby improving the cooling effect on the container body 110.

[0062] In combination with the above situation, the way in which the foaming material device sets the first filling space 660 and the second filling space 670 can not only solve the problem of a gap between the outer wall and the insulation layer due to the uneven surface of the storage container 100, but also can specify the formation of a relatively thin insulation layer in the first filling space 660 and a relatively thick insulation layer in the second filling space 670 according to the insulation requirements of the storage container 100, thereby eliminating the defect in the prior art that it is difficult to eliminate the formation of an air layer between the insulation material and the temperature control component 120 when the thickness of the insulation material is relatively thick, thereby ensuring the temperature control effect of the temperature control component 120 in the storage container 100 and the insulation requirements of the container body 110.

[0063] Specifically, when the storage container 100 is placed in the filling station 210 and covered by the cover assembly 600, a first distance is formed between the temperature control channel 121 and the filling station 210, and a second distance is formed between the temperature control channel 121 and the cover assembly 600. Both the first and second distances are greater than the distance between the container body 110 and the cover assembly 600 in the first direction. This arrangement is adapted to the condition that the temperature control member 120 is located outside the container body, so that the insulation layer formed outside the temperature control channel 121 is thicker than the insulation layer of the container body 110.Figure 7 The first thermal insulation layer on the container body 110 has a first thickness in the first direction, and the temperature control channel 121 forms a second thermal insulation layer with a second thickness at the second interval. When the air enters the first thermal insulation layer and the second thermal insulation layer, the moisture inside the air is absorbed by the first thermal insulation layer and the second thermal insulation layer. Since the thickness of the second thermal insulation layer is thicker than that of the first thermal insulation layer, it is more difficult for the moisture to contact the outer surface of the temperature control channel 121, thereby preventing the formation of condensed water.

[0064] <Pushing assembly 500>

[0065] Referring to Figure 2 The pushing assembly 500 includes a plurality of push pins 510 arranged in the first direction, and the cover assembly 600 has corresponding through holes for each push pin 510 to pass through. In the projection direction perpendicular to the first direction, the pushing assembly 500 is located farther away from the filling station 210 than the cover assembly 600. It should be noted that since the cover assembly 600 needs to form a filling space with the storage container 100 on the filling station 210, arranging the pushing assembly 500 outside the cover assembly 600 in the first direction can minimize the occupation of the filling space by the pushing assembly 500, thereby meeting the filling requirements of the storage container 100.

[0066] Further combining Figure 1 The bracket 200 has a fixedly arranged top plate 230 and a plurality of support rods 220 arranged in the first direction for supporting the top plate 230. The pushing assembly 500 includes a first moving plate 520 movably arranged on the plurality of support rods 220. Each push pin 510 is in the form of a thin rod and is fixedly arranged on the first moving plate 520 to move relative to the first moving plate 520. In this embodiment, the support rod 220 is a guide member arranged on the bracket 200, and the first moving plate 520 is guided by the support rod 220 to move in the first direction. Each push pin 510 is distributed on the first moving plate 520 corresponding to the fixed support point of the storage container 100 to meet the requirement that the storage container 100 is fixed on the filling station 210. The push pins 510 are uniformly or nearly uniformly distributed on the first moving plate 520, and the interval between two adjacent push pins 510 is the same or close to the interval. The interval can be provided with a corresponding tolerance range, for example, 2 cm, which can ensure that the force of each push pin 510 acting on the storage container 100 is uniform, thereby enhancing the force application effect and enabling the relative force generated by each push pin 510 due to the tight storage container 100 to be uniformly fed back to the first moving plate 520, thereby making the overall structure stable and reliable.

[0067] It can be expanded so that the position of each ejector pin 510 on the first movable plate 520 is adjustable, such as by fixing the ejector pin 510 on the first movable plate 520 by means of a threaded connection, or when the ejector pin 510 passes through the first movable plate 520, nuts are respectively provided on the opposite sides of the ejector pin 510 passing through the first movable plate 520, which cooperate with the external thread of the ejector pin 510, and the ejector pin 510 is fixed to the first movable plate 520 by means of a double nut locking method. In this way, the ejector pin 510 can adjust its position in the first direction relative to the first movable plate 520 according to the height requirement of the storage container 100 on the corresponding support point, so that when the first movable plate 520 moves each ejector pin 510 to fix the storage container 100, all the ejector pins 510 or the corresponding ejector pins 510 for support can accurately and effectively act on the outer surface of the storage container 100 in the first direction. In this embodiment, refer to Figure 1 The first movable plate 520 has four linear bearings 700 that cooperate with the four support rods 220. The first movable plate 520 moves along the first direction through the four linear bearings 700. The ejector pin 510 is provided with an external thread, and the first movable plate 520 has a threaded hole for installing the ejector pin 510. The ejector pin 510 is adjusted in position on the first movable plate 520 by cooperating with the threaded hole.

[0068] During the specific implementation of this device, after the pushing assembly 500 is driven toward the filling station 210 by the first movable member 300 and the cover assembly 600 is driven toward the filling station 210 by the second movable member 400, the first movable member 300 can continue to provide a tightening force so that the pushing assembly 500 continues to push the storage container 100 located on the filling station 210, so that the storage container 100 is fixed on the filling station 210, and the second movable member 400 continues to provide external force so that the cover assembly 600 continues to cover the filling station 210 and is sealed between the filling stations 210.

[0069] <Cover assembly 600>

[0070] See Figure 3 The cover assembly 600 includes a second movable plate 610 and a filling cover 620 fixed to the second movable plate 610. The filling cover 620 opens in a first direction toward the filling station 210. The opening profile of the filling cover 620 is larger than the outer profile of the storage container 100, and the depth of each inner surface of the inner concave space is greater than the height of the corresponding outer surfaces of the storage container 100, so that the filling cover 620 can completely cover the storage container 100. In this embodiment, the second movable plate 610 is also provided with four linear bearings 700 that cooperate with the four support rods 220. The linear bearings 700 enable the second movable plate 610 to move in the first direction. The second movable plate 610 is disposed in the first direction of the first movable plate 520. Each ejector pin 510 passes through the second movable plate 610 and then through the through hole of the filling cover 620 to enter the filling space to press against the storage container 100.

[0071] Among them, the outer edge of the opening of the filling cover 620 has a sealing edge 621, and each point of the sealing edge 621 is on the same plane perpendicular to the first direction and is folded and extended toward the outer surface of the filling cover 620. A smooth structure is set at the corresponding position of the sealing edge 621 on the filling station 210. When the filling cover 620 is pressed tightly against the filling station 210, the sealing edge 621 is sealed and fitted on the smooth structure. At the same time, the folded and extended sealing edge 621 can enhance the sealing effect of the sealing edge 621 and prevent the foaming material from leaking during filling. Of course, a groove structure that cooperates with the sealing edge 621 can also be set at the filling station 210 at a position opposite to the sealing edge 621. The sealing effect of the sealing edge 621 and the groove channel, as well as the deep inner wall of the groove, can prevent the foaming material from overflowing outside the filling cover 620. In this embodiment, the second movable plate 610 has a pouring port 650 that penetrates the filling cover 620 and is used to allow the foaming material to enter the filling space. The pouring port 650 can be provided with multiple connections to the first filling space 660 or the second filling space 670, and all pouring ports 650 are provided on the outer side wall of the filling cover 620 in the opposite direction of the first direction, that is, located at the outer side of the filling cover 620 in the height direction. As a result, the molten foaming material entering the pouring port 650 gradually fills the first filling space 660 and the second filling space 670 along the first direction. To facilitate the pouring effect, a plurality of exhaust holes 640 can be evenly arranged on the filling cover 620 to exhaust air squeezed by the foaming material during pouring.

[0072] Furthermore, a sealing cap 630 is provided on the pouring port 650. This sealing cap 630 is used to seal the pouring port 650. When the foaming material is poured, the sealing cap 630 is closed to allow the foaming material to solidify, thereby preventing external air or the environment from affecting the formation of the insulation layer of the storage container 100. The sealing cap 630 can be configured as a flip structure, with a corresponding lock provided on the outside of the pouring port 650, which is used to seal the sealing cap 630 to the pouring port 650. Of course, other sealing and fixing structures for the pouring port 650 can also be configured, which will not be detailed here.

[0073] In addition, the operator can observe the internal conditions of the filling space through the exhaust hole 640 .

[0074] <First Moving Member 300 and Second Moving Member 400>

[0075] See Figure 1 、 Figure 5 and Figure 6The support 200 is provided with a top plate 230 located at the top of the support 200 and not movable relative to the support 200 as a whole. The first moving member 300 comprises a first driving part 310 and a first screw rod 320 connected with the first driving part 310. The end of the first screw rod 320 penetrates through the top plate 230 and is rotationally connected with the top plate 230. The threaded part of the first screw rod 320 is threadedly connected with the first moving plate 520. The first driving part 310 is arranged at the end position of the first screw rod 320 to drive the first screw rod 320 to rotate. When the first driving part 310 drives the first screw rod 320 to rotate, the first moving plate 520, as a nut seat arranged on the first screw rod 320, moves along the first direction or the reverse direction of the first direction with the rotation of the first screw rod 320. The first driving part 310 can be arranged as a rotating handle to manually adjust the movement of the first moving plate 520 by the operator, or can be arranged as a driving motor to electrically drive the movement of the first moving plate 520.

[0076] Further, the second moving member 400 comprises at least two synchronous driving parts 410. The synchronous driving part 410 comprises a second driving part 411 and a second screw rod 412 connected with the second driving part 411. The end of the second screw rod 412 penetrates through the first moving plate 520 and the top plate 230, is rotationally connected with the top plate 230 without affecting the movement of the first moving plate 520, and the threaded part of the second screw rod 412 is threadedly connected with the second moving plate 610. The second driving part 411 is arranged at the end position of the second screw rod 412 to drive the second screw rod 412 to move. When the second driving part 411 drives the second screw rod 412 to rotate, the second moving plate 610, as a nut seat arranged on the second screw rod 412, moves along the first direction or the reverse direction of the first direction with the rotation of the second screw rod 412. The second driving part 411 can also be arranged as a rotating handle to manually adjust the movement of the second moving plate 610 by the operator, or can be arranged as a driving motor to electrically drive the movement of the second moving plate 610.

[0077] In this embodiment, at least two synchronous drive members 410 are distributed on both sides of the first mobile member 300, and the first screw 320 and the second screw 412 are arranged along the first direction. The two synchronous drive members 410 are arranged on both sides of the first mobile member 300 to provide stable power output for the cover assembly 600 without affecting the operation of the first mobile member 300 and to prevent uneven force on the support 200 in the support direction. Two synchronous drive members are provided, one on each side of the first mobile member 300. Because the support force required for the weight of the cover assembly 600 is greater than that required for the push assembly 500, multiple synchronous drive members 410 are provided to drive the cover assembly 600 to ensure stable movement. At least two synchronous drive members 410 drive the cover assembly 600 in a synchronous drive process. During the movement of the cover assembly 600 driven by the second mobile member 400, the driving speeds of the synchronous drive members 410 are consistent, allowing the cover assembly 600 to move along the first direction toward the filling station 210 without deflection.

[0078] exist Figure 1 In the specific structure, a synchronization member 800 is provided between each synchronous driving member 410. The second screw rod 412 on each synchronous driving member 410 rotates synchronously via the synchronization member 800, wherein the synchronization member 800 includes a synchronization wheel 810 provided on each second screw rod 412 and a synchronization belt 820 connected to the synchronization wheel 810. Each synchronization wheel 810 is located on the same plane at the corresponding position of each second screw rod 412, and the plane is perpendicular to the first direction. When one of the synchronous driving members 410 is driven, it can drive the other synchronous driving members 410 to move, thereby synchronously moving the cover assembly 600 in the first direction. Figure 5 and Figure 6 In the illustrated embodiment, two synchronous drive members 410 are provided, the synchronous wheel 810 is located at the same height of the two second screws 412, and the synchronous belt 820 connected to the synchronous wheel 810 crosses the first screw 320 without contacting the first screw 320. When the second driving portion 411 of one of the synchronous drive members 410 is driven, the synchronous belt 820 drives the second screw 412 of the other drive member to rotate, so that the cover assembly 600 moves.

[0079] In addition, the positioning member 240 is provided as a positioning protrusion on the filling station 210, and the positioning protrusion is adapted to the container opening of the container body 110 to fix the storage container 100 on the filling station 210. Of course, other positioning structures such as positioning blocks, positioning grooves, etc. can also be provided, which will not be described in detail here.

[0080] In addition to the foaming material filling device described in the above embodiments, the present invention also provides a foaming material filling method.

[0081] See Figure 8The foam material filling method is applied to a foam material filling device and comprises the following steps:

[0082] S100, controlling the first moving member 300 to move the push assembly 500 to the first position, and controlling the second moving member 400 to move the cover assembly 600 to the second position;

[0083] S200, placing the storage container 100 in the filling station 210, controlling the first moving member 300 to move the pushing assembly 500 in a first direction until the pin on the pushing assembly 500 fixes the storage container 100 on the filling station 210;

[0084] S300 , controlling the second moving member 400 to move the cover assembly 600 along the first direction so that the cover assembly 600 is covered on the storage container 100 of the filling station 210 ;

[0085] S400 , pouring the foaming material into the filling space between the storage container 100 and the cap assembly 600 from the pouring port 650 of the cap assembly 600 , and closing the sealing cap 630 of the pouring port 650 ;

[0086] S500, performing a demoulding operation after standing for a preset time.

[0087] The first position and the second position are different positions. Figure 1 , the push assembly 500 is in a first position and the lid assembly 600 is in a second position. Both the first and second positions are away from the filling station 210, leaving space between the push assembly 500 and the lid assembly 600 and the filling station 210 for placing the storage container 100. After the storage container 100 is placed on the filling station 210, the first moving member 300 drives the push assembly 500 to move in a first direction, causing each ejector pin 510 to press against a corresponding position on the storage container 100 and continuously provide a resisting force in the first direction on the storage container 100, locking the storage container 100 in place while the positioning member 240 is in place. The first moving member 300 then moves the lid assembly 600 to cover the storage container 100 in the first direction and seal it against the filling station 210, forming a filling space. The filling space is then divided into a first filling space 660 and a second filling space 670 according to the first and second regions of the storage container 100. Next, molten foaming material is poured into the filling space through the pouring port 650 of the lid assembly 600. After the filling space is filled with the foaming material, the sealing cap 630 of the pouring port 650 is closed, allowing the foaming material to take shape within the filling space, forming an insulating layer that surrounds the container body 110 and the temperature control member 120. After a predetermined period of rest, the mold can be demolded, completing the foaming material filling process.

[0088] The method provided in the embodiment of this aspect forms a fully wrapped insulation layer on the outer wall of the storage container 100 through multiple steps S100 to S500, reducing the air interlayer, and the thickness of the insulation layer in the lowest temperature area is greater, thereby increasing the heat transfer resistance, reducing not only the amount of condensation water generated in the interlayer gap, but also the amount of condensation water generated outside the insulation layer. The formed storage container 100 has good insulation performance.

[0089] In some embodiments of the present invention, a plurality of pouring ports 650 are provided on the cap assembly 600 so that the foaming material is uniformly injected into the filling space from the pouring ports 650 to fill the filling space. Thus, the step of pouring the foaming material from the pouring ports 650 of the cap assembly 600 into the filling space between the storage container 100 and the cap assembly 600 in S400 includes:

[0090] The filling amount is determined based on the size of the filling space, and the foaming material is evenly filled into each filling port 650 according to the filling amount.

[0091] Since the size of the filling space is fixed, the total amount of foaming material to be poured is determined based on the size of the filling space, and the foaming material is evenly poured through each pouring port 650 to gradually fill the filling space and prevent the foaming material from overflowing. What can be expanded is to divide the filling space into multiple even filling areas, and set a pouring port 650 corresponding to each filling area. When the foaming material is evenly poured into the pouring port 650, the filling speeds in each filling area are close, thereby ensuring the orderly progress of the filling process. Furthermore, the pouring speed of the foaming material can be controlled to meet the filling degree of the foaming material in the filling space. When the filling degree of the foaming material in the filling space is low, the filling speed of the foaming material can be appropriately accelerated. When the filling degree becomes high, such as when the filling amount reaches 70%, the filling speed of the foaming material is reduced to prevent the filling speed from being too fast and causing the foaming material to overflow, thereby ensuring the orderly progress of the filling process.

[0092] In one embodiment, each of the filling ports 650 is at the same height, that is, the distance between each of the filling ports 650 and the filling position in the first direction is the same, see Figure 1 When the bracket 200 is set up in a standing position, the filling station 210 is located at the bottom of the bracket 200, and the corresponding filling ports 650 are at the same height. This can ensure that when each filling port 650 is filled, the filling liquid level in the filling space reaches each filling port 650 at the same time, avoiding overflow due to a lower filling port 650 at a certain location.

[0093] In another embodiment, the foam material filling device further includes a space avoider, which is installed on the storage container 100 and is used to replace components that have not yet been installed on the storage container 100. In this embodiment, the space avoider includes a first space avoider and a second space avoider. The first space avoider is used to replace the temperature adjustment component 122, and the second space avoider is used to replace the control circuit board. Because the temperature adjustment component 122 and the control circuit board may be affected by the foam material, the use of the space avoider can reserve corresponding space avoidance locations for installing the temperature adjustment component 122 and the control circuit board, and form a thermal insulation layer structure that fits the above two components.

[0094] Therefore, placing the storage container 100 into the filling station 210 includes a preliminary step of installing a space avoidance member on the storage container 100 .

[0095] In yet another embodiment, the demolding operation in S500 includes sequentially executing a first movement step and a second movement step, wherein the first movement step includes controlling the second movable member 400 to drive the lid assembly 600 away from the filling station 210, and the second movement step includes controlling the first movable member to drive the push assembly 500 away from the filling station 210. Demolding is performed in this order, with the lid assembly 600 first being separated while the push assembly 500 remains locked to the storage container 100. This prevents mold defects caused by the insulation layer being carried by the filling lid 620 during demolding, thereby ensuring smooth demolding. Finally, the push assembly 500 is removed from the storage container 100, and the storage container 100, now filled with foam material, is placed in a position on the filling station 210, thereby completing the demolding operation. This demolding operation is simple and effective, ensuring effective separation between the insulation layer and the lid assembly 600.

[0096] In another aspect, the present invention further provides a method for preparing a storage container 100, the method comprising a filling preparation step and the foam material filling method described in the above embodiment, wherein the filling preparation step comprises:

[0097] S1, the cover assembly 600 and the push assembly 500 are movably installed on the bracket 200 through the guide member;

[0098] S2, installing the first movable member 300 on the bracket 200, so that the first movable member 300 is connected to the pushing assembly 500;

[0099] S3 , installing the second moving member 400 on the bracket 200 , connecting the second moving member 300 to the cover assembly 600 , and connecting the synchronization member 800 to each synchronization driving member 410 of the second moving member 400 .

[0100] In S1, see Figure 1After the internal components of the cover assembly 600 are assembled, the filling cap 620 is fixed to the second movable plate 610 by screw connection or other means. The second movable plate 610 has four second connection holes respectively set at four diagonal positions. The second connection holes are slidably mounted on the guide member, i.e., the support rod 220 of the bracket 200, via linear bearings 700, completing the first installation step of the cover assembly 600. The ejector assembly 500 is positioned above the cover assembly 600. After the internal components are assembled, the ejector pin 510 is fixedly mounted on the first movable plate 520. The first movable plate 520 of the ejector assembly 500 has four first connection holes respectively set at four diagonal positions. After the cover assembly 600 is installed, the first connection holes are slidably mounted on the guide member via linear bearings 700.

[0101] In S2 and S3, the first screw 320 and the second screw 412 are both rotatably mounted on the top plate 230 of the bracket 200. The first drive unit 310 and the second drive unit 411 are respectively engaged with the first screw 320 and the second screw 412. In this case, the synchronous wheel 810 of the synchronization member 800 is pre-installed on the second screw 412. When the top plate 230 is subsequently installed on the bracket 200, the corresponding synchronous belt 820 is inserted into the synchronous wheel 810. Subsequently, the first screw 320 is connected to the first movable plate 520 of the ejection assembly 500, and the second screw 412 is connected to the second movable plate 610 of the cover assembly 600, completing the assembly process. In this case, the relative positions of the ejector pins 510 on the first movable plate 520 can be adjusted so that each ejector pin 510 is pressed against the storage container 100 of the filling station 210, completing the filling preparation step.

[0102] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Anyone skilled in the art can utilize the above-disclosed practices and technical content to make numerous possible variations and simple substitutions to the present invention without departing from the scope of the present invention, and all such variations and substitutions are within the scope of protection of the present invention.
