Description

TECHNICAL FIELD

[0001] The utility model relates to reagent production technical field especially relates to a reagent bottle automatic positioning mechanism. BACKGROUND

[0002] Reagent is pure chemical substance for chemical reaction, detection, analysis or synthesis. It is widely used in chemical, biological, pharmaceutical and other fields, and is the basic material of scientific research and production. The types include analytical reagent, biochemical reagent, indicator and the like. They are used for qualitative or quantitative analysis, synthesis of new compounds or verification of chemical reactions in the laboratory. Reagents are divided into industrial grade, chemical purity, analytical purity and superior purity according to purity, and the higher the purity, the more accurate the experimental results. Therefore, in order to ensure the purity of reagents, current automatic industrial production is adopted.

[0003] When the reagent is completed, in order to effectively store and transport the reagent, the reagent needs to be stored in the matching reagent bottle in time. Specifically, the reagent bottle is sent into the conveying track in advance, and then conveyed to the filling equipment by the conveying track, and unified filling is carried out by the filling equipment. After filling, it is sent to the cap screwing device by the conveying track, and the cap screwing device is assembled. Although the prior art can complete the foregoing process, the cap is smaller than the reagent bottle, and in the process of conveying the reagent bottle on the conveying track, the bottle opening of the reagent bottle needs to be accurately aligned with the cap screwing device to smoothly assemble the cap. In actual state, it is inevitable that various uncontrollable external factors will cause different degrees of error in the conveying process, which will ultimately affect normal production.

DETAILED DESCRIPTION

[0017] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0018] The application discloses an automatic positioning mechanism for reagent bottles, which comprises clamping devices 1, a calibration device 2 and a pre-positioning device 3. The clamping devices 1 correspond to a cap screwing device. When the clamping devices 1 embrace each other, the bottle mouth of the reagent bottle matches the cap screwing device. Specifically, the calibration device 2 comprises calibration rods 21, an assembling block 22 and an adjusting knob 23. The number of the calibration rods 21 is at least three. The calibration rods 21 are arranged along the X, Y and Z axes. The assembling block 22 is provided with through holes perpendicular to each other. The assembling block 22 is sleeved on the calibration rods 21 so that the adjacent two calibration rods 21 are perpendicular to each other. The calibration device 2 further comprises the adjusting knob 23. The adjusting knob 23 is screwed into the assembling block 22. The end of the adjusting knob 23 abuts against the calibration rods 21.

[0019] The clamping devices 1 are arranged on the two sides of a conveying track respectively. The clamping device 1 comprises a cylinder 11 and a positioning claw 12. The extending end of the cylinder 11 is connected with the positioning claw 12. The extending ends of the cylinders 11 are oppositely arranged so that the positioning claws 12 embrace each other. The positioning claw 12 abuts against one of the calibration rods 21. The positioning claw 12 comprises a bottle body positioning claw 121, a bottle mouth positioning claw 122 and a connecting rod 123. The bottle mouth positioning claw 122 corresponds to the bottle mouth of the reagent bottle. The bottle body positioning claw 121 corresponds to the bottle body of the reagent bottle. The bottle body positioning claw 121 is connected with the cylinder 11. One end of the connecting rod 123 is connected with the bottle mouth positioning claw 122, and the other end of the connecting rod 123 is connected with the bottle body positioning claw 121. The connecting rod 123 is arranged along the vertical direction. The connecting rod 123 abuts against one of the calibration rods 21.

[0020] The pre-positioning device 3 is arranged on one side of the clamping device 1 so that the conveying direction of the conveying track is directed by the pre-positioning device 3 to the clamping device 1. The pre-positioning device 3 comprises a chuck 31 and a stepping motor 32. The chuck 31 is connected with the output end of the stepping motor 32. The chuck 31 is provided with chuck grooves corresponding to the bottle body of the reagent bottle. The number of the chuck grooves is plural. The chuck grooves are arranged along the circumferential direction of the chuck 31.

[0021] In actual application, the relative position relationship between the cap screwing device and the clamping device 1 is determined in advance. Then, the position of the calibration rods 21 is adjusted according to the determined relative position. The relative position between the calibration rods 21 is adjusted by rotating the adjusting knob 23 to disengage the adjusting knob 23 from the calibration rods 21, sliding the assembly block 22, and then rotating the adjusting knob 23 to abut against the calibration rods 21. Thus, the position of the calibration rods 21 is fixed by the friction between the adjusting knob 23 and the calibration rods 21. Therefore, the calibration rods 21 are arranged along the X, Y and Z axes, and a reference point in space is determined by adjusting the position of the calibration rods 21. The reference point matches the cap screwing device. Since the connecting rods 123 are arranged in the vertical direction, the position of one clamping device 1 matches the reference point and the cap screwing device by abutting one of the calibration rods 21 against the connecting rod 123.

[0022] During operation, the conveying track continuously conveys the reagent bottles. When the reagent bottles are conveyed to the pre-positioning device 3 by the conveying track, the chucks 31 are rotated by the stepping motors 32, so that the reagent bottles can enter the clamping grooves of the chucks 31. Thus, the two chucks 31 clamp the reagent bottles on the left and right sides of the reagent bottles, and preliminarily position the reagent bottles. Then, the chucks 31 are continuously rotated by the stepping motors 32, so that the chucks 31 are released to the clamping devices 1. Thus, the pre-positioning device 3 preliminarily positions the reagent bottles and separates the abutting reagent bottles, so as to facilitate the clamping of the clamping devices 1.

[0023] When the conveying track conveys the reagent bottles to the clamping devices 1, the cylinders 11 act to abut the positioning claws 12. The bottle body positioning claws 121 and the bottle mouth positioning claws 122 are connected by the connecting rods 123 and simultaneously act to push the bottle body and the bottle mouth of the reagent bottles. Thus, the reagent bottles are finally positioned. Through the foregoing adjustment process, the position of one clamping device 1 matches the reference point, i.e., matches the cap screwing device. During the positioning process, the positioning claws 12 of the other clamping device 1 are moved to abut against the clamping device 1. The action parameters of the cylinders 11 of the two clamping devices 1 can also be pre-set by using the determined reference point. Thus, through the foregoing action process, the bottle mouth of the reagent bottles matches the cap screwing device, so that the assembly of the bottle cap can be normally performed.

[0024] Therefore, the positioning position of the reagent bottle can be effectively calibrated, and the adverse effect of the error on the cap assembling process is effectively reduced.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
