Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filling operation, in particular to a kind of online weighing system after filling. BACKGROUND

[0002] In vitro detection reagent needs to be filled into reagent bottle 1 such as Figure 1 As shown in the figure, reagent placement area 1-1 is provided on the cavity thereof, and reagent needs to be filled into reagent placement area 1-1, and in the prior art, after filling reagent placement area 1-1, in order to detect whether the filled reagent reaches the set weight, the reagent bottle needs to be taken down to obtain the actual filling weight of each reagent bottle, since the reagent bottle needs to be taken down, and then the reagent bottle needs to be transported by additional transfer equipment, which leads to relatively complex entire production cycle, and since the weighing station and the filling station are separated, once the weight of the reagent in the reagent bottle does not meet the standard, it needs to be returned to the filling station again for replenishment, which further leads to production lag; Therefore, it is urgent to develop a system capable of online weighing to shorten the production node and improve the production efficiency. SUMMARY

[0003] In view of the above problems, the present application provides a kind of online weighing system after filling, which directly carries out weighing operation after reagent bottle is filled with reagent, shortens production node, and improves production efficiency.

[0004] An online weighing system after filling, characterized in that it comprises: A reagent bottle conveying line is provided with a plurality of reagent bottle placement racks arranged at equal intervals along the length direction of the line body, each reagent bottle is clamped and supported by the two side arms of the reagent bottle placement rack from top to bottom, and the reagent bottle conveying line comprises an upper conveying line and a lower return line, the upper conveying line is provided with a reagent bottle filling and weighing station along the length direction, and the reagent bottle conveying line is step-conveyed. A filling mechanism comprising a mounting frame, a tank and a filling and discharging mechanism; An online weighing mechanism comprising a separate rack, a connecting rod support, a synchronous lifting driving mechanism and a plurality of separate weighing assemblies, each separate weighing assembly comprising a pair of reagent bottle clamps and a high-precision electronic scale. The reagent bottle filling and weighing station covers at least two reagent bottle placement racks, a plurality of pairs of reagent bottle clamps are arranged at intervals between the two connecting rods of the connecting rod support, the output ends of the synchronous lifting driving mechanisms are respectively correspondingly arranged on the two sides of the connecting rod support, the lifting driving mechanism drives each reagent bottle clamp to support the corresponding reagent bottle after filling, at this time, the side arms of the corresponding reagent bottle placement rack are in an open state, and the high-precision electronic scale corresponding to each reagent bottle clamp is arranged on the upper part of the separate rack.

[0005] Further characterized in that: After all the reagent bottle racks covered by the reagent bottle filling and weighing station are filled with unfilled reagent bottles, the tank synchronously fills the reagent bottles with a set weight of reagent through the filling and discharging mechanism to the actual placement area of the reagent bottles, and then the corresponding reagent bottle clamp of the connecting rod support is placed directly below the reagent bottle under the driving of the synchronous lifting driving mechanism. At this time, the side arm of the corresponding reagent bottle rack is opened, the reagent bottle is supported by the reagent bottle clamp, and then the synchronous lifting driving mechanism drives the reagent bottle to descend to the corresponding high-precision electronic scale for weighing operation. After the weighing is completed, the synchronous lifting driving mechanism drives the reagent bottle to rise to the side arm clamping position of the original reagent bottle rack, and then the side arm of the reagent bottle rack clamps the reagent bottle, and the synchronous lifting driving mechanism drives the connecting rod support to descend to the initial position. The initial position of the connecting rod support and the reagent bottle clamp is located in the area between the upper conveying line and the lower return line. When the high-precision electronic scale is weighing, the reagent bottle clamp is completely separated from the reagent bottle, so that only the reagent bottle is supported on the high-precision electronic scale. When the weight of the reagent in the corresponding reagent bottle is small, when the reagent bottle is reset to be clamped by the side arm of the reagent bottle rack, the corresponding filling and discharging mechanism is driven to supplement the reagent to the reagent bottle until the reagent amount of all the reagent bottles is qualified.

The upper layer of the independent rack is provided with a mounting and fixing table, and a plurality of high-precision electronic scales are fixedly installed on the mounting and fixing table, so that the high-precision electronic scale is completely separated from the bottom machine table, preventing the equipment vibration from affecting the weighing accuracy. The synchronous lifting driving mechanism is a diagonal driving mechanism, and two groups of synchronous lifting driving mechanisms are synchronously lifted. The diagonal driving mechanism makes the reagent bottle clamp completely separate from the reagent bottle when the high-precision electronic scale is weighing, so that only the reagent bottle is supported on the high-precision electronic scale. Preferably, two line bodies are arranged on both sides of the width direction of the reagent bottle conveying line, and the line bodies rotate circularly. The reagent bottle conveying line simultaneously drives two groups of reagent bottles to move forward in parallel, which improves the operation efficiency of the whole production line.

[0006] After all the reagent bottles covered by the reagent bottle filling and weighing station are filled with reagents by the filling mechanism, the connecting rod support drives the corresponding reagent bottle clamp to be placed right below the reagent bottle under the drive of the synchronous lifting drive mechanism, at this time, the side arm of the corresponding reagent bottle placing rack is opened, the reagent bottle is supported by the reagent bottle clamp, then the synchronous lifting drive mechanism drives the reagent bottle to descend to the corresponding high-precision electronic scale to perform the weighing operation, after the weighing is completed, the synchronous lifting drive mechanism drives the reagent bottle to ascend to the side arm clamping position of the original reagent bottle placing rack, then the side arm of the reagent bottle placing rack clamps the reagent bottle, and the synchronous lifting drive mechanism drives the connecting rod support to descend to the initial position; after the reagent bottle is filled with reagents, the weighing operation is directly performed, the production node is shortened, and the production efficiency is improved.
