DETAILED DESCRIPTION

[0025] Reference Figures 1 to 6 The embodiments of the present invention are further described.

[0026] A grabbing and loading mechanism for tube valves on a blood bag production line includes two vibrating plates 01 for conveying reflux valves and round tubes, respectively, and a mounting frame 001 corresponding to the two vibrating plates 01. The mounting frame 001 is provided with a transmission unit 03 cooperating with the two vibrating plates 01, a feeding unit 04 corresponding to the welding device 002, and a grabbing unit 02 for transferring the two reflux valves and round tubes to the unloading table 26.

[0027] The transmission unit 03 includes a first track 1 for conveying the reflux valve, a second track 2 for conveying the round tube, a material support seat 3 corresponding to the first track 1, a movable block 4 movably connected to the outlet of the first track 1, and a baffle 5 installed on the second track 2. The first track 1 and the second track 2 are both installed on the mounting frame 001 and are respectively connected to the two vibration disks 01. The baffle 5 is arranged at the outlet of the second track 2. The material support seat 3 is provided with two material receiving spaces 301 for placing the two reflux valves respectively. The material support seat 3 is movable on the mounting frame 001, and a first cylinder 6 is installed on the mounting frame 001. The output end of the first cylinder 6 is connected to the material support seat 3, and the material receiving space 301 can correspond to the outlet of the first track 1.

[0028] The grabbing unit 02 includes a clamping part 051 for grabbing the reflux valve onto the material support seat 3, and a material suction rotating part 052 for transferring the two reflux valves and the round tube to the feeding unit 04. The clamping part 051 includes a material support seat 3 movable on the mounting frame 001, a clamp 7 for clamping the reflux valve, a second cylinder 8 for controlling the opening or clamping of the clamp 7, a fixed seat 9 for installing the clamp 7, and a third cylinder 10 for driving the fixed seat 9 to move on the mounting frame 001.

[0029] During use: the two vibrating disks 01 work to transfer the reflux valve and the round tube to the first track 1 and the second track 2 respectively. Under the action of one vibrating disk 01, the reflux valve entering the first track 1 continuously pushes the front reflux valve to move toward the outlet of the first track 1. Under the action of the other vibrating disk 01, the round tube entering the second track 2 continuously pushes the front round tube to move toward the outlet of the second track 2. When the reflux valve and the round tube move to the outlet of the first track 1 and the outlet of the second track 2 respectively, the movable block 4 restricts the reflux valve within the first track 1, and the baffle 5 restricts the round tube within the second track 2. The first cylinder 6 works to drive the material support seat 3 to move so that a material receiving space 301 on the material support seat 3 corresponds to the outlet of the first track 1. At this time, the movable block 4 is controlled to move downward so that the movable block 4 cannot block the outlet of the first track 1.

[0030] In cooperation with the clamping member 051, the second cylinder 8 drives the clamp 7 to clamp the reflux valve at the outlet of the first track 1 into a material receiving space 301 on the material support seat 3, and controls the movable block 4 to move upward so that the movable block 4 blocks the outlet of the first track 1 to prevent the reflux valve in the first track 1 from separating from the first track 1. The first cylinder 6 works again to drive the material support seat 3 to move so that another material receiving space 301 on the material support seat 3 corresponds to the outlet of the first track 1. At this time, the movable block 4 is controlled to move downward so that the movable block 4 cannot block the outlet of the first track 1. The clamping member 051 works again, and the second cylinder 8 drives the clamp 7 to clamp the reflux valve at the outlet of the first track 1 into another material receiving space 301 on the material support seat 3, so that there are two reflux valves on the material support seat 3.

[0031] Cooperate with the material suction rotating part 052 to transfer the two reflux valves on the material support seat 3 and a round tube at the outlet of the second track 2 to the discharge table 26 of the feeding unit 04, so as to facilitate the feeding unit 04 to be transported to the subsequent welding device 002 for further subsequent processing, thereby achieving convenient loading of the round tube and the two reflux valves. There is no need to grab the round tube and the two reflux valves one by one onto the discharge table 26. The round tube and the two reflux valves can be grabbed as a group onto the carrier plate at the same time, thereby improving loading efficiency.

[0032] The suction rotary member 052 works, and after transferring the two reflux valves and the round tube as a group to the feeding unit 04, the suction rotary member 052 resets and moves the two reflux valves and the round tube as a group to the unloading table 26 of the feeding unit 04 again, so that the feeding unit 04 can transport two groups of tube valves to the fusion welding device 002 at one time, further improving the loading efficiency, and facilitating the operation of processing two blood bags at the same time in the subsequent process, thereby improving the production efficiency of blood bags.

[0033] A guide plate 11 is installed at the exit of the first track 1, the movable block 4 is U-shaped, and the guide plate 11 is provided with two movable holes 12 which are respectively movably connected to the two ends of the movable block 4. A fourth cylinder 13 is installed on the mounting frame 001, and the output end of the fourth cylinder 13 is connected to the movable block 4; the fourth cylinder 13 drives the movable block 4 to move up and down, realizing the up and down movement of the movable block 4 on the guide plate 11, thereby realizing the up and down movement of the movable block 4 by controlling the movable block 4 to block the reflux valve in the first track 1, and will not hinder the movement of the clamp 7 when the clamp 7 extends into the first track 1 to clamp the reflux valve out to the material receiving space 301 of the material support seat 3.

[0034] Four partitions 14 are installed on the material support seat 3, and each material receiving space 301 is formed by two partitions 14. The setting of the partition 14 facilitates the formation of the material receiving space 301 and prevents the reflux valve from being offset on the material support seat 3 and affecting the transfer of the reflux valve by the material suction rotating part 052.

[0035] The material suction rotating member 052 includes a motor 15, a frame 16, a material suction head 17, a fifth cylinder 18 and a vacuum pump 19. The material suction head 17 is provided with a suction pipe 20. The number of the suction pipe 20 is the sum of the number of the reflux valves and the number of the round tubes. The number of the suction pipe 20 is at least three. A suction nozzle 25 is installed on the suction pipe 20. An air guide pipe 21 is installed on the frame 16. The two ends of the air guide pipe 21 are respectively connected to the suction pipe 20 and the vacuum pump 19. The vacuum pump 19 is installed on the mounting frame 001. A lifting seat 22 is installed on the mounting frame 001. The motor 15 is installed on the lifting seat 22. A turntable 23 connected to the output end of the motor 15 is installed on the frame 16. A guide rod 24 is movably connected to the frame 16. One end of the guide rod 24 is connected to the output end of the fifth cylinder 18, and the other end of the guide rod 24 is connected to the material suction head 17. The material suction head 17 is L-shaped.

[0036] The two reflux valves and the round tube are transferred to the feeding unit 04 as a group through the suction rotating member 052. Specifically, the motor 15 drives the turntable 23 to rotate, thereby rotating the frame 16 on the turntable 23, so that the suction head 17 moves to correspond to the material supporting seat 3, and cooperates with the vacuum pump 19 to generate negative pressure through the air guide pipe 21 on the suction pipe 20 of the suction head 17, so that the suction pipe 20 has suction force, and the fifth cylinder 18 drives the guide rod 24 to move downward, so that the suction head 17 connected to the guide rod 24 moves downward, so that the two suction pipes 20 on the suction head 17 suck and fix the two reflux valves on the material supporting seat 3, and cooperates with the fifth cylinder 18 to drive the guide rod 24 to move upward and the motor 15 to rotate the suction head 17 on the frame 16 to correspond to the outlet of the second track 2, so that the fifth cylinder 18 controls the guide rod 24 to move downward so that a suction pipe 20 on the suction head 17 sucks and fixes a round tube in the second track 2, sucking The setting of the nozzle 25 makes it convenient to suck and fix the round pipe or reflux valve more firmly. The fifth cylinder 18 controls the guide rod 24 to move upward to lift the suction head 17, and cooperates with the motor 15 to continue working to rotate the suction head 17 on the frame 16 to stop corresponding to the discharge platform 26. Cooperate with the vacuum pump 19 to stop working to make the suction force of the suction pipe 20 disappear, so that the reflux valve and round pipe sucked and fixed on the suction pipe 20 fall on the discharge platform 26 of the feeding unit 04, which is convenient for the feeding unit 04 to be subsequently transported to the fusion welding device 002 for subsequent processing, and the purpose of transferring the two reflux valves and round pipes as a group to the feeding unit 04 is achieved through the operation of the suction rotating member 052. Cooperate with the motor 15 to control the turntable 23 to reset, the vacuum pump 19 works again to make the suction head 17 suck and fix the two reflux valves and round pipes as a group through the suction pipe 20 and transfer them to the discharge platform 26, so that the feeding unit 04 can transport two groups of pipes and valves to the fusion welding device 002 at one time, which is conducive to speeding up production efficiency.

[0037] The feeding unit 04 includes a discharge table 26, a sixth cylinder 27, a guide seat 28 and a fixed plate 29. The discharge table 26 is provided with a accommodating chamber 30 for placing two return valves and a round tube. There are two accommodating chambers 30. The sixth cylinder 27 is installed on the mounting frame 001. The guide seat 28 is connected to the output end of the sixth cylinder 27. The discharge table 26 is movably connected to the guide seat 28. A sliding rod 34 is installed on the mounting frame 001. The guide seat 28 is provided with a guide hole 35 movably connected to the sliding rod 34 and a mounting groove 36 corresponding to the seventh cylinder 31. The seventh cylinder 31 is installed in the mounting groove 36, and the output end of the seventh cylinder 31 extends out of the mounting groove 36 and is connected to the discharge table 26. The eighth cylinder 32 is installed on the mounting frame 001. The fixed plate 29 is connected to the output end of the eighth cylinder 32, and a clamping block 33 cooperating with the accommodating chamber 30 is installed on the fixed plate 29.

[0038] The suction rotary member 052 is used to transfer the two return valves and the round tube as a group to the corresponding unloading platform 26 and place them in a accommodating chamber 30. After the suction rotary member 052 is reset, the two return valves and the round tube are transferred as a group to the corresponding unloading platform 26 and placed in another accommodating chamber 30. The two return valves and the round tube are placed in the accommodating chamber 30 as a group to prevent the two return valves and the round tube from being offset when they fall on the unloading platform 26, which affects the subsequent processing accuracy. The sixth cylinder 27 works to drive the guide The seat 28 moves toward the fixed plate 29, and makes the two accommodating chambers 30 correspond to the two clamping blocks 33, cooperates with the seventh cylinder 31 to drive the discharge table 26 close to the clamping block 33, and the eighth cylinder 32 drives the fixed plate 29 to make the clamping block 33 close to the discharge table 26, so that the clamping block 33 limits and fixes the reflux valve and the round tube in the accommodating chamber 30, so that the needle extraction mechanism on the subsequent fusion welding device 002 can be accurately connected with the reflux valve and the round tube, thereby transferring the two sets of tube valves to the fusion welding device 002.
