[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 1, the automatic solution suction control device provided by the embodiment of the present invention includes a controller 1, a breaking-off mechanism 2 and a suction mechanism 3, wherein the controller 1 is electrically connected to the breaking-off mechanism 2 and the suction mechanism 3, respectively.
The controller 1 sets the motion parameters of the breaking-off mechanism 2 and the pumping parameters of the pumping mechanism 3; the breaking-off mechanism 2 is electrically connected with the controller 1 and is used for receiving the motion parameters and driving the container to move and/or rotate according to the motion parameters, and the container is placed at a container placing position of the breaking-off mechanism 2; the pumping mechanism 3 is electrically connected with the controller 1 and is used for receiving the pumping parameters and pumping the solution in the container according to the pumping parameters.
In the embodiment, the automatic solution suction control device drives the container to move to the position where the suction mechanism 3 can suck the solution through the breaking-off mechanism 2, and then sucks the solution through the suction mechanism 3. Generally, the breaking-off mechanism 2 drives the container to move in the vertical direction; the motion parameters of the breaking-off mechanism 2 set by the controller 1 may be the moving distance, the moving speed and the rotation angle of the breaking-off mechanism 2, or may be the final moving position, the moving speed and the rotation angle of the breaking-off mechanism 2; the pumping parameters of the pumping mechanism 3 can be the pumping amount and the pumping speed of the pumping mechanism 3, and staff can set the motion parameters and the pumping parameters of different types of containers in advance, so that the device is convenient to directly call the parameters when in use, and the motion parameters and the pumping parameters can be manually set through the controller 1 according to the pumping requirement of actual production.
Preferably, the pumping mechanism 3 pumps the solution simultaneously when the breaking-off mechanism 2 moves the container, so as to reduce pumping time. When the sucking mechanism 3 sucks the solution by using a needle with a rigid structure, the moving speed of the breaking-off mechanism 2 can be reduced along with the reduction of the distance between the needle and the bottom of the bottle, and when the needle point of the needle contacts the bottom of the bottle, the breaking-off mechanism 2 stops moving, so that the bottom of the bottle is prevented from being punctured due to the overhigh moving speed of the breaking-off mechanism 2. Specifically, when the needle tip of the pumping mechanism 3 contacts the solution level in the container, the moving speed of the breaking-off mechanism 2 may start to decrease, and the decrease of the moving speed by the factor may be calculated by the following formula: hs-Hn≥HbX n, wherein HsThe final position of the container, which is preset for the breaking-off mechanism 2 to drive, can be calculated according to the motion parameters of the breaking-off mechanism 2; hnThe current position of the breaking-off mechanism 2 can be obtained according to a motor of the breaking-off mechanism 2; hbBeing containersThe height from the bottle neck to the bottle bottom is n, which is a multiple of the reduction of the moving speed of the breaking-off mechanism 2, and generally, in practical application, the value of n may be 0.3, that is, 0.3 times of the initial moving speed.
After the pumping mechanism 3 completely pumps the rated solution amount in the container, a certain pumping time can be added to ensure that the solution in the container is completely pumped. A certain pumping time can be set according to the volume of the container, and can be 1-3 seconds, and the larger the volume, the longer the pumping time can be.
Further, as shown in fig. 2, the breaking-off mechanism 2 includes a moving unit 21 and a removing unit 22, the moving unit 21 is used for driving the container to move and/or rotate, and the removing unit 22 is used for removing the bottle head of the container when the container needs to be removed to suck the solution. When the automatic solution suction control device provided by the embodiment of the invention is used, the container for containing the solution can be a glass container such as an ampoule bottle, and when the solution in the bottle needs to be sucked, the bottle head of the ampoule bottle needs to be removed, so that the suction mechanism 3 can smoothly suck the solution in the bottle.

The needle comprises a hose and needle heads arranged at two ends of the hose, the peristaltic pump 32 comprises a roller and a roller driving part connected with the roller, the roller driving part can drive the roller to roll, the hose of the roller press-fit medicine dispenser 31 controls the suction speed and the suction amount of the solution, and the movement direction of the roller is controlled to control the flow direction of the liquid in the medicine dispenser 31. The moving stroke of the roller is related to the flow rate of the solution, and the relationship between the moving stroke of the roller and the flow rate of the solution can be expressed by the following formula by adopting a correction coefficient: p ═ C/R, where P is the correction factor, R is the number of revolutions of the roller of the peristaltic pump 32, and C is the flow rate of the solution, for example, 0.8ml of solution, the correction factor being 0.8. The solution in the containers with various specifications and capacities can be subjected to multiple suction tests, and the average solution flow corresponding to one circle of rotation of the roller corresponding to the solution in the containers with various specifications and capacities is counted to serve as a correction coefficient. The use of correction coefficient makes things convenient for the device to come accurate control through the motion stroke of gyro wheel to the suction volume of solution more, if the suction volume is inaccurate, or the motion stroke of gyro wheel is inconsistent with the final suction volume of solution, then can adjust the further suction effect of optimizing of correction coefficient.

When the suction mechanism 3 adopts a needle with a rigid structure to suck the solution, the sensor 4 is adopted to determine the position of the bottom of the container bottle, so that whether the needle point of the needle contacts the bottom of the container bottle can be determined in the movement process of the breaking-off mechanism 2, the bottom of the container bottle is prevented from being punctured by the needle, and accidents are avoided. Specifically, the sensor 4 may be mounted on the dispensing device 31 of the suction mechanism 3, during the movement of the breaking-off mechanism 2, if the needle tip of the needle of the dispensing device 31 touches the bottom of the bottle, the bottom of the bottle will apply a driving force to the dispensing device 31, i.e. the sensor 4 can be triggered, the sensor 4 feeds back a signal to the controller 1, the device can determine the position of the bottom of the container, and if the signal of the sensor 4 disappears again, the needle tip leaves the bottom of the bottle or punctures the bottom of the bottle, so the sensor 4 can also be used for early warning the occurrence of an accident.

In the automatic solution suction control method provided by the embodiment of the invention, the container for containing the solution can be a glass container such as an ampoule bottle, and when the solution in the bottle needs to be sucked, the head of the ampoule bottle needs to be removed, so that the suction mechanism can smoothly suck the solution in the bottle.
