DETAILED DESCRIPTION

[0022] Refer to the attached Figure 1-5 , an infusion clamping mechanism, comprising an infusion bottle placed inside a box body 1, wherein the infusion bottles are arranged in a single row, multiple rows or a circle in the box body 1, and the infusion bottles are fixed to the inner wall of the box body 1 by buckles, wherein the infusion bottles arranged in a single row, multiple rows or a circle are respectively connected with a first infusion transmission mechanism 2, a second infusion transmission mechanism 3 and a third infusion transmission mechanism 4;

When the first motor 5 is started, the guide plate 7 moves horizontally in the X direction on the first screw 6;

[0024] The second infusion transmission mechanism 3 includes a second motor 8 fixed on the guide plate 7, the output shaft of the second motor 8 extends to the first driving wheel 9, the first driving wheel 9 and the first driven wheel 10 are connected by a first conveyor belt 11, and an infusion tube bottle 12 is fixed on the first conveyor belt 11 by a positioning pin, and when the second motor 8 is started, the first conveyor belt 11 can be driven to transmit, and the infusion tube bottle 12 moves horizontally in the Y-axis direction on one side of the first conveyor belt 11;

[0025] The third infusion transmission mechanism 4 includes a third motor 13 placed on the box body 1, the output shaft of the third motor 13 extends to the first bevel gear 14, the outer wall of the first bevel gear 14 is meshed with a second bevel gear 15, the rotating shaft of the second bevel gear 15 passes through the panel and extends to the second driving wheel 16, the second driving wheel 16 and the second driven wheel 17 are connected by a second conveyor belt 18, and the second conveyor belt 18 between the second driving wheel 16 and the second driven wheel 17 is arranged corresponding to the infusion bottle arranged in a circular shape. As the third motor 13 is started, the conveyor belt drives the infusion tube bottle 12 to perform a circular rotation and fix it at the corresponding infusion bottle position.

[0026] A specific embodiment of the present scheme is that a clamping mechanism 19 adapted thereto is installed on the infusion tube bottle 12, and the clamping mechanism 19 includes a fourth motor 20, and the output shaft of the fourth motor 20 extends to the second screw 21, and a clamping block 22 fixed on the infusion tube plug is spirally driven on the outer wall of the second screw 21, and the clamping block 22 is connected with a strip groove adapted thereto along the height direction of the guide plate 7, and as the fourth motor 20 is started, the clamping block 22 drives the infusion tube plug to move up and down.

[0027] A specific embodiment of the present scheme is that the first motor 5 and the fourth motor 20 are distributed vertically, and the output shaft of the first motor 5 and the first screw 6, as well as the output shaft of the fourth motor 20 and the second screw 21 are installed and fixed by a coupling, the output shaft of the second motor 8 and the vertical center line of the first driving wheel 9 are maintained on the same axis, and the bottom end of the first conveyor belt 11 is provided with a rolling groove connected to the frame.

[0028] A specific embodiment of the present scheme is that the first bevel gear 14 and the second bevel gear 15 are vertically arranged, and the transmission ratio between the second bevel gear 15 and the first bevel gear 14 is 1:1. By setting the above transmission ratio, power can be transmitted smoothly, so that the second conveyor belt 18 can be connected and rotated smoothly.

[0029] The specific embodiment of this scheme is that, since there are three types of infusion bottles, namely soft bags, plastic infusion bottles and glass bottles, and these three types are of different sizes, the axial fixation adopts a spring hook form so that the infusion bag can be hung vertically, and we adopt three forms of one row, two rows and circle in its arrangement; in the one-row arrangement, the infusion tube bottle 12 manipulator clamping block 22 goes in the X direction, and the transmission mode of the manipulator clamping block 22 is screw spiral transmission or gear belt transmission, in the two-row arrangement, the infusion tube bottle 12 manipulator clamping block 22 goes in the X\Y direction, and the transmission mode of the manipulator clamping block is screw spiral transmission or gear belt transmission, and it may be a mixed transmission mode, such as worm gear transmission in the X direction, belt transmission direction in the Y direction, and vice versa;

[0030] The infusion tube bottle 12 is arranged in a circle, and the clamping block of the manipulator for inserting the infusion tube into the bottle moves in a circle, and the transmission mode of the manipulator is gear belt transmission; the bottle mouth fixing mechanism of the infusion tube bottle 12 adopts a card structure. When the mouth of the infusion bottle is put into the card station, it will be automatically detected (sensor detection). At this time, the motor will rotate to make the card position stuck, so that the infusion tube bottle insertion manipulator will move when inserting the infusion tube bottle into the mouth of the infusion bottle, and cannot be inserted; the working principle is that the motor drives the rotating wheel, and then drives the infusion bottle station gear to rotate through the conveyor belt transmission, so that the station cam clamps the bottle mouth of the infusion bottle.

[0031] The specific embodiment of this scheme is as follows: Figure 1 It can be seen that for a single-row infusion set, a spiral transmission method can be directly used to directly transport the infusion tube bottle to the corresponding position. This design method is simple, reasonable and fast, and it is compatible with the docking work of the infusion set. In addition, the output shaft of the fourth motor 20 extends to the second screw 21, and the outer wall of the second screw 21 is spirally driven with a clamping block 22 fixed on the infusion tube plug. The transmission mechanism of the fourth motor 20 can move up and down through the lifting movement, so that the infusion tube bottle 12 can be well docked with the bottle mouth.

[0032] The specific embodiment of this scheme is as follows: Figure 1 and 2 It can be seen that for multiple infusion sets, the screw drive and the conveyor belt are combined to perform respective movements in the X and Y axis directions, thereby being able to drive the infusion tube bottle 12 to move in the direction and position of any point in the plane.

[0033] The specific embodiment of this scheme is as follows: Figure 3 It can be seen that the conveyor belt itself is arranged in a circular shape. This arrangement is to adapt to the annular arrangement of the infusion set in the box 1. In addition, the third infusion transmission mechanism 4 is provided with a guide wheel connected to the second conveyor belt 18. It can be seen that the guide wheels are distributed around the conveyor belt, which can play an effective biasing and guiding role, thereby preventing the conveyor belt from deviating from its position during the transmission process.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
