DETAILED DESCRIPTION

[0027] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1-Figure 8 As shown, a transmission device for medical device production includes a conveyor line body 1, and multiple groups of rack components 5 are installed at equal intervals on the outer side of the conveyor belt on the conveyor line body 1. The rack component 5 includes a mounting plate 51, and the mounting plate 51 is fixedly installed on the conveyor line body 1 by bolts. A top block 52 is installed on the right side of the top of the mounting plate 51, and two groups of sealing clips 53 are fixedly installed on the left side of the top of the mounting plate 51. A swing frame 54 is rotatably installed on the right side of the top of the mounting plate 51, and the swing frame 54 can swing back and forth, and the top block 52 is located on the inner side of the swing frame 54;

[0029] The top of the swing frame 54 is provided with a plurality of guide rods 55 in an annular shape, and the tops of the plurality of guide rods 55 are fixedly connected with sleeves 56 at the same time. The inner diameter of the sleeves 56 is larger than the outer diameter of the centrifuge tube. The top of the sleeves 56 is provided with a plurality of elastic chucks 57 in an annular shape, and the inner sides of the plurality of elastic chucks 57 are fixedly connected with rubber nozzles 58 at the same time. The bottom of the sleeves 56 is fixedly connected with a telescopic rubber sleeve 59, and the bottom of the telescopic rubber sleeve 59 is fixedly installed with a bottom sleeve 510, and the bottom sleeve 510 contacts the top block 52, so that the centrifuge tube can be rotated. The tube can be tightly inserted into the bottom sleeve 510, a tension spring 511 is arranged between the bottom sleeve 510 and the swing frame 54, a plurality of sets of torque limiting hoops 512 are arranged in a ring shape on the outer side of the telescopic rubber sleeve 59, the torque limiting hoops 512 are sleeved on the guide rod 55, a transmission rope 516 is arranged between the top of the bottom sleeve 510 and the inner side of the elastic clamp 57, a rope hole is opened inside the sleeve 56, the transmission rope 516 passes through the rope hole, an air pipe 6 is arranged at the bottom of the telescopic rubber sleeve 59, and the air pipe 6 is connected to the high-temperature steam and negative pressure equipment.

[0030] The material of the bottom sleeve 510 is made of nylon, and there is extrusion friction between the bottom sleeve 510 and the centrifuge tube. The telescopic rubber sleeve 59 is made of silicone rubber, which is resistant to high temperatures (up to 200°C), has good elasticity, and has a thickness of 5mm. When steam is passed through, the telescopic rubber sleeve 59 can expand and can be tightly attached to the centrifuge tube when inhaling.

[0031] During transportation, the sleeve 56 opens upwards, and under the action of the top block 52, the bottom sleeve 510 approaches the sleeve 56, the telescopic rubber sleeve 59 is compressed, the transmission rope 516 is relaxed, and the elastic chuck 57 is in an outwardly expanded state under the action of its own elastic force. The manipulator inserts multiple centrifuge tubes into the sleeve 56 at one time, and tightly inserts them into the bottom sleeve 510. Under the guiding action of the elastic chuck 57, the insertion stability is high. After the insertion is completed, the conveying line body 1 drives the rack assembly 5 to move, and the rack assembly 5 drives the centrifuge tube to move. While moving, the swing frame 54 is controlled to swing downward, and the swing frame 54 drives the sleeve 56 to swing to the horizontal. Under the action of the tension spring 511, the bottom sleeve 510 is close to the top block 52, so when the sleeve 56 swings to When horizontal, the bottom sleeve 510 drives the telescopic rubber sleeve 59 to unfold, and the bottom sleeve 510 drives the centrifuge tube to completely enter the sleeve 56, and the bottom sleeve 510 drives the elastic clamp 57 to close inward through the transmission rope 516, and the elastic clamp 57 closes the rubber mouth 58 together, and the closed rubber mouth 58 enters between the two sets of sealing clips 53. Under the action of the clamping force of the sealing clips 53, the rubber mouth 58 is tightly closed to block the opening of the sleeve 56, and then high-temperature steam is introduced through the air pipe 6. After the high-temperature steam enters, the telescopic rubber sleeve 59 expands under the action of air pressure, so that the centrifuge tube has enough disinfection space. In a limited space, only a small amount of high-temperature steam is needed to fully disinfect the centrifuge tube, and the disinfection cost is low;

[0032] After a period of time, when the centrifuge tube is transported to the capping station, the inside and outside of the centrifuge tube are completely disinfected. At this time, the swing frame 54 is controlled to swing upward, and the swing frame 54 drives the sleeve 56 to swing until the opening is facing upward. Under the action of the top block 52, the bottom sleeve 510 is close to the sleeve 56, the telescopic rubber sleeve 59 is compressed, and the transmission rope 516 is relaxed. The elastic clamp 57 is in an outward expansion state under the action of its own elastic force. The threaded portion of the centrifuge tube is located above the elastic clamp 57, and the air pipe 6 is connected to the external negative pressure equipment. Negative pressure is generated inside the telescopic rubber sleeve 59, and the telescopic rubber sleeve 59 is tightly attached to the centrifuge tube. Through the setting of the torque limiting hoop 512, the circumferential limiting force of the telescopic rubber sleeve 59 is relatively large, so the clamping force of the telescopic rubber sleeve 59 and the bottom sleeve 510 on the centrifuge tube is sufficient to clamp the centrifuge tube for capping. At this time, the capping equipment can directly cap the centrifuge tube without the need for additional clamping equipment.

[0033] By setting up the transmission device of the present invention, centrifuge tubes can be stably transported and sterilized efficiently and energy-savingly, and a set of capping and clamping equipment can be saved, with good transmission effect. Centrifuge tubes transported by the present invention can be directly packaged subsequently without the need for further disinfection.

[0034] On the basis of the above embodiment, it also includes that a synchronous pulley 2 is fixedly installed on the outer side of the conveying wheel on the conveyor line body 1, a synchronous installation belt 3 is sleeved on the outer side of the synchronous pulley 2, a plurality of groups of combined connectors 4 are fixedly installed on the outer surface of the synchronous installation belt 3, the air pipe 6 is connected to the combined connector 4, and every five groups of air pipes 6 are connected to one group of combined connectors 4.

[0035] At present, most of the manipulators in the factory clamp and convey five groups of centrifuge tubes at a time, so these five groups can be controlled together. Through the setting of the combined connector 4, the control is convenient, and through the setting of the synchronous pulley 2 and the synchronous mounting belt 3, the combined connector 4 and the rack assembly 5 are guaranteed to run synchronously, which is not easy to cause pipeline entanglement.

[0036] On the basis of the above embodiment, a guide sleeve is provided on the outer side of the bottom sleeve 510, and the guide sleeve is sleeved on the guide rod 55. Through this design, the bottom sleeve 510 can be lifted and lowered stably.

[0037] On the basis of the above embodiment, the top of the sealing clip 53 is further designed to be bent outwards, so that the rubber nozzle 58 that is closed together can easily enter the sealing clip 53.

[0038] On the basis of the above embodiment, it also includes that a worm gear 513 is fixedly installed on the outer side of the swing frame 54, a worm 514 is rotatably installed on the outer side of the mounting plate 51, the worm 514 is meshed with the worm gear 513, a transmission wheel 515 is fixedly installed on the right side of the worm 514, and a lower tooth block 8 and an upper tooth block 9 are installed on the top of the conveyor line body 1, and the transmission wheel 515 can mesh with the lower tooth block 8 and the upper tooth block 9.

[0039] A slide groove 7 is provided at the top of the conveyor line body 1, and T-shaped slide irons are provided at the bottom of the lower tooth block 8 and the upper tooth block 9. The T-shaped slide irons are slidably connected in the slide groove 7. The T-shaped slide irons are commonly used mechanical parts and do not require mold manufacturing, so the manufacturing cost is low.

[0040] Furthermore, threaded holes are provided at both ends of the T-shaped slide iron, and locking bolts are threadedly connected in the threaded holes. By setting the locking bolts, the upper gear block 9 and the lower gear block 8 can be quickly moved to any position.

[0041] By arranging the lower tooth block 8 and the upper tooth block 9 at a specific position on the conveyor line body 1, when the conveyor line body 1 drives the mounting plate 51 to move to the position of the lower tooth block 8, the transmission wheel 515 is meshed with the lower tooth block 8, and the lower tooth block 8 causes the transmission wheel 515 to rotate, the transmission wheel 515 drives the worm 514 to rotate, the worm 514 drives the worm wheel 513 to rotate, and the worm wheel 513 drives the swing frame 54 to rotate. No additional drive is required, and the structure is compact. When the transmission wheel 515 is meshed with the upper tooth block 9, the transmission wheel 515 reverses. Since the worm wheel 513 cannot drive the worm 514 to rotate, when the transmission wheel 515 is not driven, the swing frame 54 remains stable and does not swing randomly, and the transmission effect is good.

[0042] And through the arrangement of this embodiment, the installation position of the lower tooth block 8 and the upper tooth block 9 can be arbitrarily adjusted according to the actual installation position of the equipment, and the number of the lower tooth block 8 and the upper tooth block 9 can be arbitrarily increased according to demand, and the adjustable range is wide.

[0043] On the basis of the above embodiment, the conveyor line body 1 is a double-belt conveyor line, and the mounting plate 51 is installed across the double-belt conveyor line, so that the conveying is more stable.

[0044] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
