Abstract
Description
Technical Field
[0001] The present invention relates to the field of filling, and in particular to testing reagent filling equipment. Background Art
[0002] Test reagents are chemical or biological agents used to detect specific substances or biomarkers and are widely used in fields such as medical diagnosis, scientific research, and environmental monitoring. Currently, the filling process for test reagents often involves manual dosing, where the reagent bottles are placed and then transported to the filling station. This method requires further automation. Furthermore, during the manual dosing process, operators need to screen the reagent bottles to identify those with quality defects, such as cracks. However, screening bottles with less obvious cracks is more difficult. Summary of the Invention
[0003] The present invention aims to provide a detection reagent filling device to improve the automation level of filling, especially reagent bottle loading, and reduce the difficulty of screening cracked reagent bottles.
[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a detection reagent filling device, comprising a support platform, a frame mounted on the support platform, a turntable rotatably mounted on the support platform, a bottle feeding mechanism and a bottle cap feeding mechanism mounted on the support platform, and a filling mechanism and a bottle cap screwing mechanism mounted on the frame, wherein a plurality of bottle accommodating positions are provided around the turntable; The bottle feeding mechanism includes a bottle vibrating hopper, a bottle spiral track, a unified position drawing and throwing unit, an inclined transition pipe, a bottle conveying pipe and a bottle pushing unit. The bottle spiral track is arranged in the bottle vibrating hopper. The unified position drawing and throwing unit includes a unified position drawing and throwing hook. The unified position drawing and throwing hook is rotatably connected to the bottle vibrating hopper and is located above the end of the bottle spiral track. A height difference is provided between the end of the bottle spiral track and the bottle conveying pipe and they are connected by a transition pipe. The bottle conveying pipe extends to the side of the turntable. The bottle pushing unit can push the reagent bottle in the bottle conveying pipe into the bottle receiving position. The bottle cap feeding mechanism includes a bottle cap vibrating hopper, a bottle cap spiral track and a bottle cap conveying pipe. The bottle cap spiral track is arranged in the bottle cap vibrating hopper. A number of blocking grooves are provided on the bottle cap spiral track. The bottle caps with the opening facing upwards pass through the blocking grooves and are conveyed to the turntable through the bottle cap conveying pipe with the opening facing downwards. The bottle cap screwing mechanism can grab the bottle caps and put them on the reagent bottles filled by the filling mechanism and tighten them.
[0005] The beneficial effects of this solution are as follows: this equipment has a high degree of automation. During the process of filling and testing reagents, only one person is required to pour the reagent bottles into the bottle body vibrating hopper and the bottle caps into the bottle cap vibrating hopper at intervals. The reagent bottles are transported along the bottle body spiral track under the action of the bottle body vibrating hopper. When the reagent bottles pass through the unified draw-out and throwing hook, if the bottle bottoms face the conveying direction, the reagent bottles push the unified draw-out and throwing hook to rotate, and the reagent bottles slide through the inclined transition pipe to the bottle body conveying pipe; when the reagent bottles pass through the unified draw-out and throwing hook, if the bottle mouths face the conveying direction, the unified draw-out and throwing hook is inserted into the reagent bottle. As the reagent bottles push the unified draw-out and throwing hook to rotate, the reagent bottles turn around and fall into the inclined transition pipe under the action of the unified draw-out and throwing hook and then enter the bottle body conveying pipe, thereby making the reagent bottles entering the bottle body conveying pipe uniformly placed in positions; in addition, when the unified draw-out and throwing hook adjusts the direction of the reagent bottles, it realizes the random inspection and flipping of the reagent bottles, so as to increase the probability of expanding the cracks of the reagent bottles with unclear cracks that are inspected, which is convenient for the subsequent screening of cracked reagent bottles.
[0006] The reagent bottles entering the bottle conveying pipe are conveyed to the turntable and pushed into the bottle receiving position by the bottle pushing unit. Under the action of the turntable, the reagent bottles are rotated to the filling mechanism to be filled with reagents; at the same time, the bottle caps are conveyed along the bottle cap spiral track under the action of the bottle cap vibrating hopper. When the bottle caps pass through the blocking groove, only the bottle caps with the opening facing upwards can pass through, and then they are conveyed to the turntable through the bottle cap conveying pipe with the opening facing downwards, and the bottle cap screwing mechanism grabs the bottle caps to the filled reagent bottles and tightens them; the filled reagent bottles are rotated to the operator under the action of the turntable, and the operator removes the reagent bottles and puts them on the tray while inspecting the reagent bottles. Since the cracks of some defective reagent bottles have been enlarged in the unified position drawing and hooking process, this is conducive to reducing the difficulty of screening reagent bottles with cracks.
[0007] Furthermore, the bottle pushing unit includes a bottle pushing part, which includes a bottle pushing cylinder and a bottle pushing block. The bottle pushing cylinder is fixed on the support platform, and the bottle pushing block is fixedly connected to the output shaft of the bottle pushing cylinder. An opening is provided on the bottle conveying pipe extending to the side of the turntable, and the bottle pushing block is located in the middle of the opening.
[0008] Furthermore, the bottle pushing unit also includes a re-screening anti-counterfeiting part located between the opening and the turntable. The re-screening anti-counterfeiting part includes a support plate, a support rod, a torsion spring and a re-screening anti-counterfeiting block. The support plate is fixed to the bottle body conveying pipeline, the support rod is rotatably connected to the support plate, the torsion spring is sleeved on the support rod and the two ends of the torsion spring are respectively fixed to the support plate and the support rod, and the re-screening anti-counterfeiting block is fixed to the support rod. Then the bottle pushing cylinder drives the bottle pushing block to return to its position, and the reagent bottle falls onto the supporting platform, and then the bottle pushing cylinder drives the bottle pushing block to push the reagent bottle into the bottle body receiving position; in the process of the reagent bottle entering the bottle body receiving position, it contacts the re-screening anti-counterfeiting block and pushes the re-screening anti-counterfeiting block to rotate, and the reagent bottle rotates with the turntable after entering the bottle body receiving position, so that the reagent bottle and the re-screening anti-counterfeiting block move relative to each other, thereby leaving a scratch on the reagent bottle to form a unique anti-counterfeiting mark; after the reagent bottle is separated from the re-screening anti-counterfeiting block, the re-screening anti-counterfeiting block is reset under the action of the torsion spring and knocks the middle of the next reagent bottle on the pushing bottle block, so as to increase the probability of enlarging the crack of the reagent bottle with unclear cracks again. Of course, knocking on the reagent bottle without cracks will not affect the reagent bottle. Then the bottle pushing cylinder drives the bottle pushing block to return to its position, and the reagent bottle falls onto the supporting platform, and so on.
[0009] Furthermore, the unified withdrawal and throwing unit also includes an anti-collision part, which includes a connecting rod, an incomplete gear, a rack and an anti-collision rubber sheet. The connecting rod is fixedly connected to the unified withdrawal and throwing hook and is rotationally connected to the bottle body vibration hopper. The rack is slidably connected to the bottle body vibration hopper. The incomplete gear is fixedly connected to the connecting rod and can mesh with the rack. A gap is left between the end of the bottle body spiral track and the transition pipe. The anti-collision rubber sheet is fixed to the rack and the anti-collision rubber sheet is located in the gap. The beneficial effect of this solution is that compared with the bottle bottom facing the conveying direction, the bottle mouth facing the conveying direction will cause the unified withdrawal and throwing hook to rotate at a larger angle. After exceeding the normal rotation angle of the bottle bottom toward the conveying direction, the incomplete gear meshes with the rack and drives the anti-collision rubber sheet to rise through the rack, thereby separating two adjacent reagent bottles and avoiding collision with the latter reagent bottle during the process of changing direction.
[0010] Furthermore, the upper side of the anti-collision rubber sheet is coated with a marking. The beneficial effect of this solution is that when the anti-collision rubber sheet rises, the body of the reagent bottle contacts the upper side of the anti-collision rubber sheet, thereby forming a mark on the reagent bottle. The marked reagent bottle has been processed to expand the crack, which makes it easier for subsequent operators to reduce the time required to inspect the marked reagent bottle.
[0011] Furthermore, the filling mechanism includes a peristaltic pump, a filling tube, and a filling cylinder. The peristaltic pump is mounted on a frame, and the filling cylinder is mounted on a bottle cap delivery pipe. The upper end of the filling tube is connected to the peristaltic pump, and the middle of the filling tube is connected to the output shaft of the filling cylinder. The beneficial effect of this solution is that at the beginning or end of filling, the filling cylinder drives the filling tube to drip a small amount of testing reagent onto the outside of the bottle mouth. After tightening the bottle cap, a certain degree of liquid seal is formed, which helps to improve the sealing effect.
[0012] Furthermore, an arc-shaped plate is provided outside the turntable, and the arc-shaped plate is fixed to the support platform. BRIEF DESCRIPTION OF THE DRAWINGS
