Description

Technical Field

[0001] This utility model relates to the field of biological reagent filling, and in particular to a biological reagent filling device. Background Technology

[0002] In the filling process of biological reagents, the traditional manual filling method has significant drawbacks, as it is prone to leakage or bottle tipping, resulting in material waste and potentially affecting product quality. Chinese Patent Publication No. CN214087671U proposes a biological reagent filling device that, through the inclusion of a positioning component and a height-adjustable filling head structure, allows the biological reagent bottle to be placed within the positioning component, and the filling head is then raised and lowered to achieve filling, thus overcoming the shortcomings of manual filling to a certain extent.

[0003] However, this device still has certain drawbacks: it still relies on manual operation, making it impossible to achieve assembly line operation, limiting production speed, and making it difficult to meet the needs of large-scale production. In existing technologies, to meet assembly line production requirements, a combination of a conveyor, a positioning mechanism, and a filling structure is typically used. Specifically, it uses a conveyor to transport biological reagent bottles. Once the bottles reach the designated location, the positioning mechanism uses hydraulic power to clamp the bottles, and after stabilization, it activates the filling head to lift and lower for filling, thus achieving assembly line production while ensuring that the biological reagents do not spill or tip over.

[0004] However, in the above process, the lifting and lowering of the filling head and the clamping action of the positioning mechanism must be carried out sequentially, and multiple power sources are required for driving, which will lead to a significant increase in production costs and extend the time required for filling a single bottle, thus affecting the production rate.

[0005] Therefore, a biological reagent filling device is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a biological reagent filling device that allows the positioning component to operate synchronously while the filling head is descending for filling, thereby completing the clamping action on the biological reagent bottle, thus shortening the filling time required for a single biological reagent bottle, and achieving the goals of increasing production speed and reducing production costs.

[0007] To solve the above-mentioned technical problems, this utility model provides a biological reagent filling device, including a conveyor, a filling component, a positioning component, and a linkage component;

[0008] The filling assembly includes a lifting plate and a filling head;

[0009] The filling head is fixedly connected to the lifting plate and moves vertically under the lifting action of the lifting plate.

[0010] The positioning component includes two symmetrically arranged elastic blocks for clamping and positioning the biological reagent bottles conveyed by the conveyor.

[0011] The sliding direction of the elastic block is perpendicular to the conveying direction of the conveyor table;

[0012] The linkage component is disposed between the lifting plate and the two elastic blocks;

[0013] When the lifting plate rises to its highest position, the two elastic blocks retract to both sides of the conveyor table under the action of the linkage.

[0014] As the lifting plate moves the filling head to contact the mouth of the biological reagent bottle, the two elastic blocks extend under the action of the linkage to abut against the outer wall of the biological reagent bottle.

[0015] Furthermore, it also includes support frames;

[0016] The support frame is disposed outside the conveyor table;

[0017] The lifting plate is slidably installed in the gap formed between the support frame and the surface of the conveyor table;

[0018] The elastic blocks are slidably installed on both sides of the inner wall of the support frame.

[0019] Furthermore, the positioning component also includes a slide rail;

[0020] The slide rails are fixedly installed on both sides of the inner wall of the support frame;

[0021] The elastic block is slidably connected to the slide rail, and an elastic element is provided between it and the inner wall of the support frame to provide a pre-tightening force for clamping and positioning the biological reagent bottle.

[0022] Furthermore, a double-headed transmission gear is rotatably mounted on the slide rail;

[0023] The two ends of the double-headed transmission gear mesh with the upper surfaces of the linkage and the elastic block, respectively;

[0024] When the dual-headed transmission gear rotates, it drives the elastic locking block to move.

[0025] Furthermore, the linkage and the double-headed transmission gear have both an engaged state and a disengaged state;

[0026] When the linkage and the double-headed transmission gear switch from the meshing state to the disengaged state, the two elastic blocks just form a chamber for clamping and positioning the biological reagent bottle;

[0027] When the linkage is separated from the double-headed transmission gear, and the lifting plate drives the filling head to extend into the opening of the biological reagent bottle, the elastic block remains stationary under the action of the elastic member.

[0028] Furthermore, the linkage component is configured as a connecting block fixedly installed on the lifting plate;

[0029] The length direction of the connecting block is parallel to the moving direction of the lifting plate, and the outer wall has a meshing part and a smoothing part arranged sequentially from bottom to top, so as to form a meshing state and a disengaged state with the double-headed transmission gear, respectively.

[0030] Furthermore, the filling assembly also includes a solution tank;

[0031] The solution tank is located on top of the support frame and is connected to the filling head via a telescopic pipe.

[0032] Furthermore, the telescopic pipe is configured as a corrugated pipe.

[0033] Furthermore, the top wall of the support frame is connected to the lifting plate via a cylinder.

[0034] Compared with the prior art, the present invention has at least the following beneficial effects:

[0035] By setting up a filling assembly including a lifting plate and a filling head, a positioning assembly including elastic blocks, and a linkage, with the linkage located between the elastic blocks and the lifting plate, the two elastic blocks are positioned on both sides of the conveyor table under the action of the linkage when the lifting plate rises to its highest position. This ensures that the biological reagent bottles can be conveyed to the designated position by the conveyor table. Furthermore, when the lifting plate moves the filling head to contact the mouth of the biological reagent bottle, the elastic blocks can extend to abut against the biological reagent bottle under the action of the linkage. This achieves synchronous clamping of the biological reagent bottle during the descent of the filling head, thereby effectively shortening the filling time and correspondingly reducing the output of additional power sources, thus achieving the goals of increasing production speed and reducing production costs.

[0040] The biological reagent filling device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0041] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0042] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a biological reagent filling device, including a conveyor 1, a filling component 2, a positioning component 3, and a linkage component 4.

[0043] The filling assembly 2 includes a lifting plate 21 and a filling head 22. The lifting plate 21 drives the filling head 22 to move, so that the filling head 22 can extend into and fit tightly against the biological reagent bottle, thereby ensuring the stability of the filling process.

[0044] Specifically, the filling head 22 is fixedly connected to the lifting plate 21, and moves vertically under the lifting action of the lifting plate 21.

[0045] In addition, the positioning component 3 includes two symmetrically arranged elastic blocks 31 for clamping and positioning the biological reagent bottles conveyed by the conveyor 1.

[0046] It should be noted that the sliding direction of the elastic block 31 is perpendicular to the conveying direction of the conveying table 1, so as to ensure that when the elastic block 31 retracts, it will not interfere with the normal conveying of the biological reagent bottle, thus ensuring the stability of the overall filling process.

[0047] In this embodiment, the linkage 4 is disposed between the lifting plate 21 and the two elastic blocks 31.

[0048] When the lifting plate 21 rises to its highest position, the two elastic blocks 31 retract to both sides of the conveyor table 1 under the action of the linkage 4. At this time, the biological reagent bottle can be transported to the designated position under the power of the conveyor table 1 to wait for filling.

[0049] When the lifting plate 21 moves the filling head 22 to contact the mouth of the biological reagent bottle, the two elastic locking blocks 31 extend under the action of the linkage 4 to abut against the outer wall of the biological reagent bottle. That is, during the descent of the filling head 22, the two elastic locking blocks 31 move in a direction that approaches each other to complete the positioning and clamping of the biological reagent bottle. This allows only one power source to complete the functions of lowering the filling head 22 and positioning and clamping the biological reagent bottle, and the two can be carried out simultaneously. Therefore, it effectively shortens the time required in the filling process, thereby increasing the production rate and reducing the production cost.

[0050] In other embodiments, a support frame 5 is added to facilitate the installation of the filling component 2 and the positioning component 3.

[0051] Specifically, the support frame 5 is disposed outside the conveyor table 1.

[0052] The lifting plate 21 is slidably installed in the gap formed between the support frame 5 and the surface of the conveyor table 1, while the elastic locking block 31 is slidably installed on both sides of the inner wall of the support frame 5.

[0053] The positioning component 3 further includes a slide rail 32, which is fixedly installed on both sides of the inner wall of the support frame 5 to provide support for the movement of the elastic block 31.

[0054] The elastic locking block 31 is slidably connected to the slide rail 32, and an elastic element is provided between it and the inner wall of the support frame 5 to provide a pre-tightening force for clamping and positioning the biological reagent bottle. By providing the elastic element, the elastic locking block 31 can still be tightly attached to the biological reagent bottle when no external force is applied, thereby improving the positioning and clamping effect of the biological reagent bottle.

[0055] To facilitate the movement control of the elastic block 31 via the linkage 4, the slide rail 32 is further defined. Specifically, a double-headed transmission gear 33 is rotatably mounted on the slide rail 32.

[0056] The two ends of the double-headed transmission gear 33 mesh with the upper surfaces of the linkage 4 and the elastic block 31, respectively. When the double-headed transmission gear 33 rotates, it drives the elastic block 31 to move. That is, by setting the double-headed transmission gear 33 as a power conversion component, the output power generated by the linkage 4 is converted into the rotational power of the double-headed transmission gear 33, thereby correspondingly completing the movement control of the elastic block 31.

[0057] It should be noted that during the process of the filling head 22 descending to fit with the biological reagent bottle, the positioning component 3 needs to position the biological reagent bottle first in order to ensure the accurate docking of the filling head 22 with the biological reagent bottle. Therefore, after the positioning component 3 completes the positioning, the linkage 4 should no longer mesh with the double-headed transmission gear 33 to ensure that the filling head 22 can continue to descend and complete the filling operation.

[0058] Therefore, the linkage 4 needs to be further defined here. Specifically, the linkage 4 and the double-headed transmission gear 33 have an engaged state and a disengaged state.

[0059] When the linkage 4 and the double-headed transmission gear 33 switch from an engaged state to a disengaged state, the two elastic locking blocks 31 form a chamber for clamping and positioning the biological reagent bottle (e.g., Figure 2 As shown in the figure, the elastic element ensures the clamping effect on the biological reagent bottle.

[0060] When the linkage 4 is disengaged from the double-headed transmission gear 33, and the lifting plate 21 drives the filling head 22 to extend into the opening of the biological reagent bottle, the elastic locking block 31 remains stationary under the action of the elastic element. That is, at this time, the lifting plate 21 can descend while the elastic locking block 31 remains stationary, thus ensuring the smooth progress of the filling process.

[0061] In a specific example, the linkage 4 is configured as a connecting block fixedly installed on the lifting plate 21.

[0062] The length direction of the connecting block is parallel to the moving direction of the lifting plate 21, and the outer wall has a meshing part and a smoothing part arranged sequentially from bottom to top, so as to form a meshing state and a disengaging state with the double-headed transmission gear 33, respectively.

[0063] When the meshing part and the double-headed transmission gear 33 are on the same horizontal plane, and the lifting plate 21 is raised and lowered, it can drive the double-headed transmission gear 33 to rotate, thereby driving the elastic block 31 to move accordingly. When the smooth part and the double-headed transmission gear 33 are on the same plane, it indicates that the linkage 4 is separated from the double-headed transmission gear 33. At this time, the elastic block 31 is only acted upon by the elastic element to clamp and position the biological reagent bottle.

[0064] In a further embodiment, the filling assembly 2 further includes a solution tank 23, which is disposed on the top of the support frame 5 and connected to the filling head 22 via a telescopic pipe.

[0065] The telescopic pipe is configured as a corrugated pipe.

[0066] Furthermore, the top wall of the support frame 5 is connected to the lifting plate 21 via a cylinder.

[0067] In other embodiments, a method for using the biological reagent filling device is also proposed to improve the filling effect of biological reagent bottles, thereby increasing production rate and reducing production costs.

[0068] The method of using the biological reagent filling device includes the following steps:

[0069] The biological reagent bottle is transported to the preset position (i.e., below the filling head 22) via the conveyor 1;

[0070] The lifting plate 21 is controlled to descend. During the descent, the two elastic blocks 31 move in a direction that approaches each other until they come into contact with the outer wall of the biological reagent bottle and complete the positioning of the biological reagent bottle (i.e., the biological reagent bottle is located directly below the filling head 22).

[0071] When the elastic locking block 31 completes the positioning of the biological reagent bottle, the linkage 4 is just separated from the double-headed transmission gear 33. Therefore, at this time, the lifting plate 21 will descend and will no longer drive the elastic locking block 31 to move, so as to ensure the integrity of the biological reagent bottle.

[0072] The lifting plate 21 is continuously lowered so that the filling head 22 fits against the mouth of the biological reagent bottle for filling.

[0073] After filling is completed, the lifting plate 21 is raised. When it rises to a certain height, the linkage 4 and the double-headed transmission gear 33 are engaged, and the lifting plate 21 is continuously raised. Under the transmission action of the linkage 4 and the double-headed transmission gear 33, the two elastic blocks 31 are controlled to retract to both sides of the conveyor table 1. At this time, the biological reagent bottle is not limited by the elastic blocks 31, so the conveyor table 1 can be started to complete the output of the biological reagent bottle after filling.

[0074] Through the above steps, the biological reagent bottle is synchronously clamped during the descent of the filling head 22, which can effectively shorten the filling time and reduce the output of additional power sources, thereby increasing production speed and reducing production costs.

[0075] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
