Detailed Description

The present inventors have made extensive and intensive studies and, for the first time, developed an automatic reagent cup loading system having a simple structure. The automatic reagent cup loading system comprises a transmission device and a cup arranging device, wherein the transmission device comprises a base, a rack, a chain transmission mechanism, a storage hopper, an eccentric wheel mechanism and a filter cup mechanism; the cup arranging device comprises a cup arranging device, a sliding groove and an isolator. The working principle of the automatic reagent cup loading system is that the reagent cups are firstly put into the storage hopper, are taken out by the chain transmission mechanism and enter the cup sorting device, the directions of the reagent cups are sorted, and then the reagent cups slide into the isolator through the chute. The present invention has been completed based on this finding.

Wherein, the main effect of storage hopper is for placing the reagent cup, and its volume size is confirmed according to the demand. The storage hopper is provided with a sensor, and the sensor is arranged above and below the storage hopper and mainly used for detecting the following states that the reagent cup reaches the maximum capacity; second, the reagent cups have reached a minimum limit capacity. The purpose of which is to feedback the prompt to the user.

The chain transmission mechanism consists of a chain, a chain wheel, a cup hanging piece, a motor and the like. The chain wheel and the chain form a chain transmission system, and the cup hanging sheet is arranged on the chain and rotates together with the chain. The storage hopper is positioned above the chain, the chain drives the cup hanging sheet to move from the lower part of the storage hopper, the shape design of the cup hanging sheet is unique, in the moving process, the reagent cups can enter the cup hanging sheet, and then the reagent cups are taken out of the storage hopper in the continuous movement of the chain.

The eccentric wheel mechanism consists of an eccentric wheel, a linear guide rail, a movable sliding block and a transmission rod. The main purpose is to stir the reagent cups in the storage hopper, so that the probability of the reagent cups entering the cup hanging sheet is increased. When the number of the reagent cups in the storage hopper is less than a certain number, the reagent cups form a stable shell layer due to the structural characteristics of the bottom of the storage hopper, the shell layer is positioned above the chain cup hanging pieces, and the chain cannot continuously stir the reagent cups of the shell layer when carrying the cup hanging pieces, so that a mechanism is needed to stir to break the balance. The transmission rod is arranged on the frame, the eccentric wheel is fixed on the chain wheel shaft, and the inner side of the eccentric wheel is connected with the transmission rod. One end of the transmission rod is movably connected with the movable sliding block, the other side of the transmission rod, which slides, is connected with the sliding block on the linear guide rail, and the linear guide rail is fixed on the rack on the other side. When the chain wheel rotates, the eccentric wheel is driven to rotate, the rotation of the eccentric wheel drives the transmission rod to move up and down, and therefore the movable sliding block at one end of the transmission rod moves up and down. The linear guide rail is mainly used for guiding and controlling the motion precision.

The filter bowl mechanism comprises a filter bowl roller, a filter bowl motor and a filter bowl elastic sheet. Because the chain drives the cup hanging sheet to move, the movement of the reagent cups in the storage hopper is disordered, and some reagent cups are outside the cup hanging sheet, so that the smooth operation of the chain can be hindered. It is necessary to remove the reagent cups that do not enter the cup hanging sheet from the chain. The filter bowl gyro wheel is located the storage hopper top, and the filter bowl shell fragment is fixed in the chain both sides to the installation of certain angle, its shell fragment stretches out to in the chain motion track. The filter cup motor drives the filter cup roller to rotate and move in the direction opposite to the movement direction of the chain.

When the chain drives the cup hanging sheet to move, when the reagent cup which does not enter the cup hanging sheet on the chain meets the filter cup roller, the roller moves to generate an outward force, so that the irregular reagent cup moves to the other direction and falls into the storage hopper. When the irregular reagent cups positioned on the two sides of the material strip meet the filter cup elastic sheet, the movement of the chain and the elasticity of the filter cup elastic sheet generate acting force, so that the irregular reagent cups are bounced off and fall into the storage hopper.

The cup arranging device consists of a cup arranging device peripheral baffle and a cup arranging body. The inside of the cup body has a unique structural design. When the reagent cups fall into the cup arranging device from the chain mechanism end, the reagent cups fall into the sliding grooves after colliding in the cup arranging device, and the sliding grooves form a certain angle with the horizontal plane. There are two states of the reagent cup falling into the chute: one is that the ideal state falls in, so that the reagent cups do not need to be calibrated. Secondly, the reagent cup is in a non-ideal state; when the reagent cup falls into the chute from the cup arranging device, the cup edge is positioned on the surface of the chute and is in an inverted state. The chute and the horizontal plane form a certain angle, and the chute is turned over and erected under the action of gravity. Thereby arranging the reagent cups into a regular schedule order state.

The spout, spout inside is narrow, has certain length. The main functions are as follows: firstly, turning over and erecting the reagent cup in a non-ideal state; secondly, the reagent cup slides downwards along the chute from the upper part; thirdly, storing a certain amount of reagent cups for timely replenishment.

The isolator comprises an isolation disc, an isolation ring, an isolation bottom plate, a sensor, a motor and the like; the isolating ring is installed on the isolating bottom plate, and the isolating disc is installed inside the isolating ring. The sensor is mounted on the spacer ring. The motor drives the isolating ring to move when rotating. The separating disc is provided with a notch, when the reagent cup slides into the notch of the separating disc from the chute, the sensor senses the reagent cup, and if the notch is provided with the reagent cup, the reagent cup stops to wait for being taken away. If the notch does not have a reagent cup, the notch is rotated continuously and stopped when the notch rotates to have the reagent cup.

The main advantages of the invention include:

(a) the automatic reagent cup loading system is simple in structure, simple in manufacturing process of all parts and low in production cost.

(b) The automatic reagent cup loading system is simple in principle, and the unique filter cup device, the unique sorting cup and the unique sliding groove structural design are matched with each other to realize the function of the automatic reagent cup loading system.

(c) The automatic reagent cup loading system has common structural materials and no special requirements.

Examples

Fig. 1 shows a reagent cup loaded by an automatic reagent cup loading system according to the invention.

As shown in fig. 6, the present invention relates to an exemplary automatic reagent cup loading system, which comprises a transmission device and a cup arranging device. As shown in fig. 3, 3a and 4, the present invention is a typical transmission comprising a base 15, a frame 16, a chain drive 3, a hopper 6, an eccentric mechanism and a bowl mechanism. The transmission device also comprises an eccentric wheel mechanism, wherein the eccentric wheel mechanism comprises an eccentric wheel 9, a linear guide rail 13, a movable sliding block 8 and a transmission rod 7; the transmission rod 7 is arranged on the frame 16, one end of the transmission rod 7 is movably connected with one side of the movable sliding block 8, the eccentric wheel 9 is fixed on the shaft of the chain wheel, and the inner side of the eccentric wheel 9 is connected with the transmission rod 7; the other side of the movable slide block 8 is connected with a slide block connecting piece 14 on a linear guide rail 13, and the linear guide rail 13 is fixed on a machine frame 16. The filter bowl mechanism is composed of a filter bowl roller 4, a filter bowl roller motor 11 and a filter bowl elastic sheet 5.

The storage hopper 6 is opened first and a certain number of reagent cups 1 are poured into the storage hopper 6. When the sensor in the storage hopper 6 detects the reagent cup 1, the chain transmission motor 10 is started to drive the chain transmission mechanism 3 to move. The chain drive 3 is filled with cup hanging pieces 2. As shown in fig. 2, the cup holding sheet 2 has hooks at both ends and a recess in the middle, which is of a size sufficient to accommodate the reagent cups to be transferred. The cup hanging piece 2 is arranged on the chain through the hook thereof and moves together with the chain. The storage hopper 6 is positioned on the chain transmission mechanism 3, when the chain transmission mechanism 3 is driven by the chain transmission motor 10, the chain transmission mechanism 3 drives the cup hanging pieces 2 to pass through the bottom of the storage hopper 6, and the cup hanging pieces 2 and the reagent cups 1 move in a mutual friction manner, so that the reagent cups 1 move irregularly, and the reagent cups 1 with a certain probability enter the cup hanging pieces 2. The reagent cups 1 are brought out under the chain drive 3. At the same time when the chain drive motor 10 is turned on, the bowl roller motor 11 is turned on, and the bowl roller is driven to rotate. Because the cup hanging sheet 2 and the reagent cup 1 rub against each other to make the reagent cup 1 move irregularly, some of the reagent cups 1 and the cup hanging sheet 2 form a half-entering state, or the edge of the reagent cup 1 and the edge of the cup hanging sheet 2 form a staggered state, which is extremely not favorable for entering the circulation of the next action, so that the reagent cup needs to be cleaned. Thus, the filter bowl roller 4 and the filter bowl spring 5 are required to clean the reagent cups 1 in these states. The cleaning principle is as follows: the rotation of the filter bowl roller 4 is opposite to the movement direction of the chain transmission mechanism 3, the reagent cups 1 on the chain transmission mechanism 3 move linearly, and when the reagent cups touch the filter bowl roller 4, upward and opposite acting forces can be generated, so that the movement direction of the reagent cups 1 is changed, and the reagent cups fall to the storage hopper 6. And the reagent cup 1 at the edge of the chain transmission mechanism 3 generates acting force with the filter cup elastic sheets 5 at two sides in the movement, so that the state of the reagent cup 1 is changed and falls to the storage hopper 6. Thereby bringing the reagent cup in the correct state to the next work.

As shown in FIG. 5, the present invention is a typical cup arranging device, which includes a cup arranging unit 18, a chute 22, and an isolator. The isolator includes an isolation disc 20, an isolation ring 24, an isolation shoe 25, and a motor. A plurality of support columns 23 are arranged at the bottom of the cup arranging device. The cup arranging device is arranged below the transmission device, the cup arranging device is connected with the transmission device through a fastener, and the reagent cups are conveyed to the top from the transmission device through the chain transmission device and then fall to the cup arranging device freely.

When the reagent cup 1 falls into the cup arranging device 18 of the cup arranging device from the upper part of the transmission device, a specially designed channel is arranged in the cup arranging device 18, so that the reagent cup 1 collides in a certain direction and falls onto the chute 22, and the reagent cup 1 can fall onto the chute 22 and can be turned over before sliding to correct the state. And then slide down the inner elongated track of the chute 22 to the lower accumulation zone. The chute 22 has two sensors, which are mainly used to measure the number of reagent cups 1 in the collection area. When the number of reagent cups in the collection zone is below a set minimum number, the chain drive 3 is activated for loading the reagent cups 1. When the number of the reagent cups in the collection area reaches the set high number, the chain transmission mechanism 3 stops running and stops loading the reagent cups 1.

The reagent cups 1 slide into the collecting zone at the lower end of the chute 22, and a certain number of the reagent cups are collected, so that the reagent cups 1 at the topmost end of the chute 22 are extruded into the separation disc 20 under the action of gravity. The reagent cups 1 are loaded into the separator disc 20 by rotation of the separator motor. Waiting for the next job.

The automatic reagent cup loading system has the advantages of simple structure, common required manufacturing materials, simple manufacturing process of each part and low production cost. The system can be used for loading reagent cups with various shapes, and has wide application range.
