[0032] Reference Figure 1-8 The utility model provides a kind of feeding device for detection kit filling processing line, including rack 1, and conveying mechanism 2, adsorption mechanism 3 and stacking disc 4 on rack 1, conveying mechanism 2 two ends are provided with feeding part 5 and discharging part 6 respectively, feeding part 5 is mainly used to store and place the stacking disc 4 with to be filled reagent box, discharging part 6 is mainly used to store empty stacking disc 4 (i.e. the to be filled reagent box in stacking disc 4 is all transferred to next station (such as filling station) by adsorption mechanism 3 at this time), to facilitate the recycling of stacking disc 4. Conveying mechanism 2 can drive stacking disc 4 to move from feeding part 5 to the direction of discharging part 6;Adsorption mechanism 3 is located between feeding part 5 and discharging part 6, such as Figure 8As shown, the stacking disc 4 is used for placing the reagent box to be filled (such as multiple reagent boxes to be filled can be stacked in each stacking disc 4 to improve production efficiency), and the adsorption mechanism 3 is used for adsorbing and transferring the reagent box to be filled.

[0033] The feeding device for the reagent box filling processing line provided by the utility model, in use, workers can first stack multiple reagent boxes to be filled in the stacking disc 4, then place the stacking disc 4 on the feeding part 5, and drive the stacking disc 4 to move towards the discharging part 6 through the conveying mechanism 2, when the stacking disc 4 moves to the working position of the adsorption mechanism 3, the adsorption mechanism 3 adsorbs the reagent box to be filled in the stacking disc 4 and transfers it to the next working position (such as a filling working position) to carry out the next working procedure, and when the reagent boxes to be filled in the stacking disc 4 are all taken out, drive the stacking disc 4 to move to the discharging part 6 for unified recycling through the conveying mechanism 2.

[0034] Compared with the prior art, the feeding device provided by the utility model can effectively reduce the workload of workers and save the labor cost of enterprises in the early stage of filling the reagent box, and further improves the production efficiency of the entire filling processing line.

[0035] Reference Figure 1 、 4 、5, in the preferred embodiment, the feeding part 5 includes a storage seat 50, a supporting assembly 51 and a fixing assembly 52, the storage seat 50 is mainly used for storing the stacked stacking disc 4, the storage seat 50 is provided with an open bottom, the supporting assembly 51 is arranged at the bottom of the storage seat 50 and is mainly used for supporting and supporting the stacking disc 4, and the fixing assembly 52 is arranged at both sides of the storage seat 50 and is mainly used for separating the stacking disc 4 at the bottom of the containing cavity 501 from the stacking disc 4 stacked thereon, so as to ensure the orderly conveying between the stacking discs 4 (that is, the conveying mechanism 2 will not appear the stacking of the stacking disc 4 in the feeding process, and the stacking disc 4 is orderly conveyed one by one); the storage seat 50 has a containing cavity 501, the containing cavity 501 is communicated with the opening, the stacking disc 4 is placed in the containing cavity 501, and the supporting assembly 51 can vertically ascend and descend towards the containing cavity 501 through the bottom opening; the fixing assembly 52 can horizontally extend and retract towards the containing cavity 501.

[0036] Specifically, since the storage base 50 has an opening at the bottom, when the stacking tray 4 is placed in the receiving cavity 501, under the action of gravity, the stacking tray 4 will naturally fall towards the opening at the bottom of the storage base 50. At this time, the supporting component 51 moves up and down towards the receiving cavity 501 through the bottom opening, which can support the stacking tray 4. That is, when the supporting component 51 moves up towards the receiving cavity 501, it can hold (support) the stacking tray 4. When it is necessary to transport the stacking tray 4, the fixing component 52 extends and retracts horizontally toward the receiving cavity 501. When the fixing component 52 extends, it can separate the stacking tray 4 located at the bottom (referring to the bottom of the receiving cavity 501) from the other stacking trays 4 stacked on it. At this time, the fixing component 52 supports the other stacking trays 4. Then the supporting component 51 descends, and the stacking tray 4 located at the bottom loses its support and falls to the conveying mechanism 2 under the action of gravity. The conveying mechanism 2 then transports it, and so on.

[0037] In a preferred embodiment, there are multiple stacking trays 4 (only one stacking tray 4 is shown in the figure, not multiple stacked trays). The multiple stacking trays 4 are stacked sequentially in the receiving cavity 501 in the vertical direction, and there is a gap between the outer edges of two adjacent stacking trays 4. This gap allows the fixing component 52 to extend into, thereby separating the stacking tray 4 at the bottom of the receiving cavity 501 from the other stacking trays 4, and supporting the other stacking trays 4 (the so-called other stacking trays 4 refer to all stacking trays 4 except the one at the bottom, which can also be understood as all stacking trays 4 stacked on top of the bottom stacking tray 4, which may be one or multiple), thereby ensuring that the stacking trays 4 are transported in an orderly manner and avoiding the stacking of stacking trays 4.

[0038] refer to Figure 4-5In the preferred embodiment, the supporting assembly 51 comprises a first driving member 510 (such as a pneumatic cylinder or an electric push rod) and a supporting plate 511, the output end of the first driving member 510 is connected with the supporting plate 511, the first driving member 510 can drive the supporting plate 511 to move up and down in the vertical direction to support or release the stacking disc 4; the fixing assembly 52 comprises a second driving member 520 (which can also be a pneumatic cylinder or an electric push rod) and a partition plate 521, the second driving member 520 can drive the partition plate 521 to move in and out in the horizontal direction, so that the partition plate 521 extends into the gap between the bottommost stacking disc 4 and the adjacent stacking disc 4 to support the other stacking discs 4 stacked above the bottommost stacking disc 4, in the embodiment, the partition plate 521 can extend partially into the gap or extend fully into the gap. When the partition plate 521 extends into the gap, the outer edge (the outer edge refers to the edge part of the stacking disc 4) of the stacking disc 4 stacked above the bottommost stacking disc 4 abuts against the partition plate 521, so that the partition plate 521 supports the other stacking discs 4 stacked above the bottommost stacking disc 4 and also plays a role of separating the bottommost stacking disc 4 in the accommodating cavity 501.

[0039] As described above, when the first driving member 510 drives the supporting plate 511 to move up in the vertical direction, the conveying mechanism 2 can support the stacking disc 4 through the supporting plate 511 before conveying; when the conveying mechanism 2 is ready to convey, the partition plate 521 is driven by the second driving member 520 to extend into the gap between the bottommost stacking disc 4 and the adjacent stacking disc 4 to support the other stacking discs 4 stacked above the bottommost stacking disc 4, then the first driving member 510 drives the supporting plate 511 to fall, at this time, the bottommost stacking disc 4 loses the supporting force and falls onto the conveying mechanism 2, the conveying mechanism 2 starts to work and conveys the stacking disc 4, while the other stacking discs 4 do not fall down due to the support of the partition plate 521. After the stacking disc 4 is conveyed forward (i.e. in the downward direction), the supporting plate 511 is lifted again, the partition plate 521 extends into the gap between the bottommost stacking disc 4 and the adjacent stacking disc 4 again, and so on, so as to realize more orderly conveying of the stacking discs 4 and better conveying effect.

[0040] Reference Figure 1 , 2, 4, 5, in the preferred embodiment, the structure of the unloading part 6 is the same as the feeding part 5. That is, the unloading part 6 also has a storage seat 50, a supporting assembly 51 and a fixing assembly 52, which have the same structure as the feeding part 5. The difference is that the unloading part 6 is mainly used for collecting empty code shelves 4. The working process is as follows: after the reagent boxes in the code shelf 4 are sucked up, the empty code shelf 4 is transported to the unloading part 6 along with the continuous conveying of the conveying mechanism 2, then the first driving part 510 drives the supporting plate 511 to rise, the empty code shelf 4 is lifted to be located in the containing cavity 501, then the second driving part 520 drives the partition plate 521 to extend into the containing cavity 501, at this time the partition plate 521 supports the lifted empty code shelf 4 to prevent it from falling onto the conveying mechanism 2, the first driving part 510 drives the supporting plate 511 to descend to avoid blocking the following (upstream) empty code shelf 4, and so on. When the empty code shelves 4 in the storage seat 50 of the unloading part 6 are collected to a certain extent, the workers collect them uniformly. Therefore, the workload of the workers is reduced, and the overall production efficiency is improved.

[0041] Reference Figure 3 In the preferred embodiment, the conveying mechanism 2 includes a fixed seat 20, a conveying belt 21 and a power assembly 22. The fixed seat 20 is fixed to the rack 1, and the power assembly 22 can drive the conveying belt 21 to rotate relative to the fixed seat 20.

[0042] The power assembly 22 includes a motor 220, a driving wheel (not shown) and a driven wheel (not shown). The driving wheel and the driven wheel are respectively arranged at both ends of the fixed seat 20, and the conveying belt 21 is sleeved on the driving wheel and the driven wheel. The motor 220 is connected with the driving wheel, and the motor 220 can drive the conveying belt 21 to move from the feeding part 5 to the unloading part 6 through the driving wheel. When the conveying belt 21 moves, it can drive the code shelf 4 to move.

[0043] Reference Figure 2 And 3 In the preferred embodiment, the conveying mechanism 2 has two groups, and the two groups of conveying mechanisms 2 are arranged at intervals. The code shelf 4 can be placed on the conveying belt 21 of the two groups of conveying mechanisms 2, and the stability is better. The feeding part 5 and the unloading part 6 each include a supporting assembly 51, and the supporting assembly 51 is arranged between the two groups of conveying mechanisms 2. In this embodiment, the movement speed and direction of the two groups of conveying mechanisms 2 are the same, which ensures that the code shelf 4 can be stably and synchronously conveyed on the conveying belt 21, and avoids the code shelf 4 from being jammed or deviated due to the asynchronous movement of the two groups of conveying belts 21.

[0044] Reference Figure 2 And 7In the preferred embodiment, the clamping part 7 is further included, which is arranged between the feeding part 5 and the discharging part 6, and includes the third driving element 70 (such as a pneumatic cylinder) and the clamping plate 71 connected with each other. The third driving element 70 and the clamping plate 71 are arranged on both sides of the conveying mechanism 2. When the suction mechanism 3 works, the third driving element 70 can drive the clamping plate 71 to move towards the conveying mechanism 2 to clamp the stacking disc 4. When the suction mechanism 3 sucks the reagent boxes in the stacking disc 4, the stacking disc 4 needs to be clamped and fixed to avoid displacement, so as to ensure that the suction mechanism 3 can smoothly suck the reagent boxes in the stacking disc 4. Taking the third driving element 70 as a pneumatic cylinder as an example, the specific process is as follows: the pneumatic cylinder is started, the piston rod is extended, the clamping plate 71 is driven to move towards the conveying mechanism 2, and the clamping plate 71 is in close contact with the side surface of the stacking disc 4, so that the stacking disc 4 is clamped and fixed relative to the stacking disc 4 to prevent movement; after the reagent boxes are sucked, the piston rod of the pneumatic cylinder is retracted, the clamping plate 71 is driven away from the conveying mechanism 2, and the stacking disc 4 is released. At this time, the stacking disc 4 can continue to be conveyed downstream under the action of the conveying mechanism 2.

[0045] Reference Figure 7 In the preferred embodiment, the clamping part 7 further includes the guide slide rail 72 and the connecting seat 73. The guide slide rail 72 is arranged along the length direction of the rack 1, and the connecting seat 73 is slidably connected with the guide slide rail 72. The third driving element 70 is fixed on both sides of the connecting seat 73, and the output end of the third driving element 70 is connected with the clamping plate 71. The connecting seat 73 can drive the clamping plate 71 to move along the guide slide rail 72.

[0046] In the embodiment, the guide slide rail 72 is fixed on the rack 1, and the connecting seat 73 is slidably connected with the guide slide rail 72. When the connecting seat 73 moves along the guide slide rail 72, the third driving element 70 and the clamping plate 71 are also moved. Therefore, when the clamping plate 71 clamps the stacking disc 4, the clamping plate 71 can drive the stacking disc 4 to move forward (i.e. to move towards the discharging part 6) through the movement of the connecting seat 73.

[0047] For example, each stacking disc 4 displays a plurality of rows of reagent boxes to be filled (such as Figure 8As shown, the stacking disc 4 has a first row, a second row, a third row, and so on, which are spaces for placing the reagent boxes to be filled. When the adsorption mechanism 3 finishes sucking the reagent boxes in the first row, the connecting seat 73 moves forward along the guide rail 72, and the connecting seat 73 drives the clamping plate 71 to move forward at the same time. Under the clamping of the clamping plate 71, the stacking disc 4 also moves forward by a certain distance, so that the adsorption mechanism 3 sucks the reagent boxes in the second row. In this process, the conveying mechanism 2 does not need to move, and only the clamping part 7 drives the stacking disc 4 to move forward. When the reagent boxes in one stacking disc 4 are finished, the empty stacking disc 4 is conveyed to the discharging part 6 by the conveying mechanism 2. At this time, the stacking disc 4 behind is conveyed to the work station of the clamping part 7, and so on.

[0048] Reference Figure 6 In the preferred embodiment, the adsorption mechanism 3 includes a transverse driving part 30, a longitudinal driving part 31, and a suction cup 32. The longitudinal driving part 31 is arranged on the transverse driving part 30, and the suction cup 32 is connected with the longitudinal driving part 31. The transverse driving part 30 can drive the suction cup 32 to move along the transverse direction, and the longitudinal driving part 31 can drive the suction cup 32 to move up and down towards the stacking disc 4.

[0049] In this embodiment, the transverse driving part 30 can adopt a linear module structure (such as the driving mode of a sliding block and a guide rail), which is arranged along the width direction of the rack 1. The longitudinal driving part 31 is slidably connected with the guide rail of the transverse driving part 30 by a sliding block, and the transverse displacement of the suction cup 32 is achieved by a cylinder driving mode. The suction cup 32 is preferably a vacuum suction cup 32. The longitudinal driving part 31 is driven by a cylinder, and the piston rod end of the cylinder is provided with the suction cup 32. In operation, the transverse driving part 30 drives the suction cup 32 to move to the upper side of the reagent box, and then the longitudinal driving part 31 drives the suction cup 32 to move down until the suction cup 32 contacts the surface of the reagent box. At this time, the vacuum generator is started to generate negative pressure in the suction cup 32, and finally the reagent box to be filled is sucked under the action of the negative pressure. Figure 8 As shown, the reagent box to be filled is adsorbed below the suction cup 32. Then the longitudinal driving part 31 drives the suction cup 32 with the reagent box to move up, and the transverse driving part 30 drives the suction cup 32 to move transversely, so as to transfer the reagent box to the next work station for the filling process. The whole process adopts automatic operation, which does not need too much manual operation, saves labor cost, and improves production efficiency.

Those skilled in the art can make changes, modifications, replacements, and variations to the above embodiments within the scope of the present application.
