The spacing between the two groups of conveying units is adjustable, the first electric cylinder drives the sliding frame to move, and the sliding frame slides on the guide rail, and the sliding frame drives the conveying unit to move, so that the distance between the fixed plates on the two groups of conveying units changes, so as to realize the positioning and support of different syringes and blood collection needles. The rollers in the two groups of conveying units slide on the sliding shafts, and the power of the first motor can be transmitted while the rollers rotate, that is, the adjustment can also be realized when the rollers rotate.

[0012] Several of the fixed plates are hollow inside, and several of the fixed plates are slidably installed with limit plates. A second spring is connected between the limit plate and the fixed plate, and the second spring is electrically connected to the control system. The limit plate is supported and limited by the fixed plate. When the second spring is energized, the second spring pulls the limit plate and the fixed plate to be flush with each other. When the second spring is de-energized, the second spring pushes the limit plate to move outward from the fixed plate to clamp the syringe.

[0013] The feeding cylinders above the first conveyor line and the second conveyor line have the same internal structure. The feeding cylinders are installed on the frame. Multiple groups of fixed cylinders are sequentially arranged in the feeding cylinders. Two groups of guide plates are arranged on one side of the multiple groups of fixed cylinders. The gap between the two groups of guide plates is used to place syringes and blood collection needles. The visual camera is installed on the other side of the fixed cylinders.

[0014] A through groove is provided on the fixed cylinder between the guide plate and the visual camera, and the through groove passes through the fixed cylinder and the feeding cylinder, and the through groove is directly opposite to the middle of the two groups of fixed plates, and multiple groups of pressure sensors are installed on the two groups of guide plates, and a push plate is slidably installed above the two groups of guide plates, and the push plate is limited and supported by the fixed cylinder, and a reciprocating plate is connected to the push plate, and the reciprocating plate connects the push plates in multiple groups of fixed cylinders, and the output shaft of the third electric cylinder is connected to the reciprocating plate, and the third electric cylinder is installed on the feeding cylinder.

[0016] A temperature sensor is installed in the expansion bag. The temperature sensor detects the temperature of the heat-conducting medium. The control system then obtains the expansion degree of the heat-conducting medium. The control system calculates the state of the folds on the expansion bag through the expansion degree of the heat-conducting medium. The temperature sensor passes through the expansion bag and is installed on the clamping plate. The temperature sensor is electrically connected to the control system.

[0017] The jig is adapted to the syringe and the blood collection needle. The jig supports and limits the syringe to prevent the syringe from rotating and moving. The unloading line has the same structure as the conveying unit. The interior of the roller in the unloading line is an electric roller structure.

[0018] A control panel is installed on the frame, a control system is arranged in the control panel, and the first conveyor line and the second conveyor line have the same structure.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. The integrated design of press-fitting and tightening does not require the replacement of the fixture, which is more efficient. If the blood collection needle assembly is a blood collection needle that needs to be pressed, the second electric cylinder drives the blood collection needle assembly to be directly pressed onto the syringe to realize the assembly of the syringe and the blood collection needle; if the blood collection needle has threads and needs to be rotated and tightened, the control system controls the drive motor to drive the rotating plate to rotate, the rotating plate drives multiple clamping plates to rotate, the multiple clamping plates drive the blood collection needle to rotate, and the second electric cylinder drives the blood collection needle to move downward and tighten with the syringe.

[0021] 2. It can adapt to the shape of blood collection needles and syringes, and further improve the clamping effect. The flexible membrane contacts the syringe, and the thin film pressure sensor on the flexible membrane feeds back data to the control system. The control system connects the heating wire to the circuit to generate heat and conduct it to the heat-conducting medium. The heat-conducting medium expands when heated, and pushes the wrinkles on one side of the expansion bag to gradually lengthen and flatten. The expansion bag pushes the magnetorheological fluid to flow to one side of the flexible membrane. The magnetorheological fluid pushes the flexible membrane to protrude and is in a compressed state with the syringe. Since the flexible membrane is made of flexible material, the surface of the flexible membrane will be squeezed and adapted to the surface of the syringe. The control system connects the coil to the circuit, and the magnetic field generated by the coil causes the magnetorheological fluid to change from liquid to solid. The solid magnetorheological fluid is adapted to the surface of the syringe through the flexible membrane, further improving the clamping effect.

[0022] 3. Perform visual inspection on syringes and blood collection needles to ensure that defective products are not assembled. When the visual camera detects that the syringe is a qualified product, the control system energizes the second spring in the fixed plate. After the second spring is energized, each turn generates a mutually attractive magnetic field, which causes the second spring to gradually shrink. The second spring pulls the limit plate outward to make the limit plate on the first conveyor line flush with the fixed plate. After that, the third electric cylinder continues to drive the syringe to move to just above the through slot, and then the syringe falls from the through slot to the two sets of fixed plates in the first conveyor line; when the visual camera detects that the syringe is a defective product, the buzzer in the control panel alarms and feeds back the data on the control panel. The staff takes the defective product off the guide plate and continues to work to ensure that defective products are not assembled.

[0023] 4. The clamping plate adopts a flexible clamping design to avoid damage to the syringe and blood collection needle. When the clamping plate clamps the syringe or blood collection needle, the two sets of rubber plates first contact the two sides of the syringe or blood collection needle, and the flexible membrane flexibly clamps the area between the two sets of rubber plates and improves the clamping effect. The rubber plate and the flexible membrane have a certain elasticity, which can avoid directly clamping the syringe or blood collection needle. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The feeding cylinder 31 above the first conveyor line 12 and the second conveyor line 14 has the same internal structure. The feeding cylinder 31 is installed on the frame 11. Multiple groups of fixed cylinders 32 are arranged in sequence in the feeding cylinder 31. Two groups of guide plates 28 are arranged on one side of the multiple groups of fixed cylinders 32. The gap between the two groups of guide plates 28 is used to place syringes and blood collection needles. The visual camera 33 is installed on the other side of the fixed cylinder 32; a through groove is arranged on the fixed cylinder 32 between the guide plate 28 and the visual camera 33. The through groove penetrates the fixed cylinder 32 and the feeding cylinder 31. The through groove is directly opposite to the middle of the two groups of fixed plates 4. Multiple groups of pressure sensors are installed on the two groups of guide plates 28. A push plate 34 is slidably installed above the two groups of guide plates 28. The push plate 34 is limited and supported by the fixed cylinder 32. A reciprocating plate is connected to the push plate 34. The reciprocating plate connects the push plates 34 in the multiple groups of fixed cylinders 32. The output shaft of the third electric cylinder 35 is connected to the reciprocating plate. The third electric cylinder 35 is installed on the feeding cylinder 31.

[0042] The driving motor 21 is a worm gear reduction motor, which self-locks the rotating plate 22 to prevent the rotating plate 22 from rotating due to external influences. The first electric cylinder 45, the second electric cylinder 15, the third electric cylinder 35, the first motor 44, the transverse module 16 and the driving motor 21 are all equipped with built-in pressure sensors and encoders.

[0043] The working principle of the present invention is as follows: the staff place multiple syringes and multiple blood collection needles in the fixed cylinder 32 above the first conveyor line 12 and the second conveyor line 14 respectively, and the syringes and the blood collection needles are respectively located between the two groups of guide plates 28 in the fixed cylinder 32. Taking the conveying of syringes as an example below, the pressure sensor on the guide plate 28 on the lower side of the syringe feeds back the pressure data to the control system, and the control system obtains the number of syringes after processing. The control system controls the third electric cylinder 35 to pull the reciprocating plate and the push plate 34 to move, and the push plate 34 pushes the syringe to move a certain distance toward the visual camera 33 and one side of the through groove. The visual camera 33 identifies the size of the syringe and feeds back the data to the control system. The control system determines whether the syringe is a qualified product after data comparison.

[0044] When the visual camera 33 detects that the syringe is a qualified product, the control system energizes the second spring 47 in the fixed plate 4 (the fixed plate 4 on the first conveyor line 12). After the second spring 47 is energized, each turn generates a mutually attractive magnetic field, which causes the second spring 47 to gradually shrink. The second spring 47 pulls the limit plate 46 to move outward, so that the limit plate 46 on the first conveyor line 12 is flush with the fixed plate 4. After that, the third electric cylinder 35 continues to drive the syringe to move to the top of the through slot, and then the syringe falls from the through slot to the two sets of fixed plates 4 in the first conveyor line 12;

[0045] When the visual camera 33 detects that the syringe is a defective product, the buzzer in the control panel 1 will sound an alarm and feed back the data on the control panel 1. The staff will take the defective product off the guide plate 28 and continue to work.

[0046] When the syringe falls from the through slot to between the two groups of fixed plates 4 in the first conveyor line 12, the two groups of fixed plates 4 support and limit the raised part on the upper side of the syringe, and the control system controls the second spring 47 to cut off the power according to the feedback data of the visual camera 33. The second spring 47 gradually becomes longer under the action of its own elastic force, and the second spring 47 pushes the limiting plate 46 to clamp the syringe in place. Afterwards, the control system controls the first motor 44 to drive the sliding shaft to rotate through the coupling, the sliding shaft drives the roller 42 to rotate, the roller 42 drives the transmission belt 41 to move, and the transmission belt 41 drives the fixed plate 4 and the syringe to move.

[0047] When the transmission belt 41 transports the syringe to one side of the first conveyor line 12, the encoder in the first motor 44 feeds back data to the control system, and the control system drives the lifting plate 2, the second electric cylinder 15, the lifting plate 2, the drive motor 21 and the rotating plate 22 to move to the side close to the first conveyor line 12 through the transverse module 16, so that the multiple groups of clamping plates 23 on the rotating plate 22 are located directly above the syringe, and the control system energizes the first spring 27 according to the displacement data of the transverse module 16. Each turn of the first spring 27 generates a magnetic field that attracts each other. The magnetic field shortens the first spring 27 while pulling the clamping plate 23 to move radially outward, so that the spacing between the multiple clamping plates 23 is greater than the diameter of the syringe, and the second electric cylinder 15 drives the multiple clamping plates 23 to move downward to cover the syringe. After that, the control system de-energizes the first spring 27 according to the data of the encoder in the second electric cylinder 15. The first spring 27 gradually becomes longer under the action of its own elastic force, and the multiple groups of first springs 27 respectively push the multiple clamping plates 23 to move radially inward to clamp the syringe in position.

[0048] After the multiple clamping plates 23 clamp the syringe in place, the flexible film 24 on one side of the clamping plate 23 contacts the syringe, and the thin film pressure sensor on the flexible film 24 feeds back data to the control system. The control system connects the heating wire 263 to the circuit to generate heat and conduct it to the heat-conducting medium 261. The heat-conducting medium 261 expands when heated and pushes the folds on one side of the expansion bag 26 to gradually lengthen and flatten. The expansion bag 26 pushes the magnetorheological fluid to flow toward one side of the flexible film 24. The magnetorheological fluid pushes the flexible film 24 to protrude and be in a compressed state with the syringe. Since the flexible film 24 is made of a flexible material, the surface of the flexible film 24 will contact the syringe. The surfaces of the syringe are squeezed and adapted to each other, and the thin film pressure sensor on the flexible membrane 24 feeds back data to the control system. The control system connects the coil 25 to the circuit. The magnetic field generated by the coil 25 causes the magnetorheological fluid to change from liquid to solid. The solid magnetorheological fluid adapts to the surface of the syringe through the flexible membrane 24, further improving the clamping effect. After that, the control system energizes the second spring 47, and the second spring 47 pulls the limit plate 46 to release the syringe. The transverse module 16 drives the clamped syringe to move to the top of the fixture 3, and the second electric cylinder 15 drives the syringe to move downward and place it on the fixture 3. The fixture 3 is the prior art.

[0049] After the syringe is placed on the jig 3, the encoder in the second electric cylinder 15 feeds back data to the control system. The control system controls the multiple first springs 27 to be energized. The multiple first springs 27 all pull the multiple clamping plates 23 to move radially outward. The multiple clamping plates 23 loosen the syringe so that the syringe falls on the jig 3. The jig 3 supports and limits the syringe.

[0050] After the syringe falls on the fixture 3, the thin film pressure sensor on the flexible membrane 24 feeds back data to the control system, and the control system cuts off the power to the heating wire 263 and the coil 25, so that the heating wire 263 no longer generates heat, and the heat of the heat-conducting medium 261 gradually shrinks while the heat is reduced. The expansion bag 26 gradually shrinks under the action of its own elastic force, and the magnetorheological fluid changes from solid to liquid after losing the magnetic field of the coil 25. After that, the control system controls the second electric cylinder 15 to drive the clamping plate 23 to move upward, and the horizontal module 16 drives the clamping plate 23 to move to one side of the second conveyor line 14. The process of conveying the blood collection needle by the second conveyor line 14 and the upper fixed cylinder 32 is the same as the conveying process of the syringe. It is first detected by the visual camera 33, and then the blood collection needle is pushed to fall from the through slot by the push plate 34 above the second conveyor line 14, and then positioned by the two sets of fixed plates 4 on the second conveyor line 14. After that, it is conveyed to one side of the second conveyor line 14 by the transmission belt 41 to realize the conveying of the blood collection needle;

[0051] When the transverse module 16 drives the multiple clamping plates 23 to be located directly above the blood collection needle, the second electric cylinder 15 drives the multiple clamping plates 23 to move downward to cover the blood collection needle, and the control system cuts off the power to the first spring 27. The first spring 27 pushes the clamping plates 23 to move radially inward under the action of its own elastic force, and the flexible membrane 24 contacts the surface of the blood collection needle.

[0052] After the flexible membrane 24 contacts the blood collection needle assembly, the thin film pressure sensor on the flexible membrane 24 feeds back data to the control system. The control system energizes the heating wire 263 again, and the heating wire 263 transfers heat to the heat-conducting medium 261, so that the heat-conducting medium 261 expands due to the heat and pushes the expansion bag 26 to move toward the side of the magnetorheological fluid. The expansion bag 26 pushes the magnetorheological fluid to move toward the side of the flexible membrane 24, so that the flexible membrane 24 protrudes and is pressed tightly against the blood collection needle. After that, the control system connects the coil 25 to the circuit. The magnetic field generated by the coil 25 causes the magnetorheological fluid to change from liquid to solid, thereby improving the clamping effect. The second electric cylinder 15 drives the clamped blood collection needle to move upward, and the horizontal module 16 drives the blood collection needle to move to just above the fixture 3. The second electric cylinder 15 drives the blood collection needle to move downward and assemble it with the syringe on the fixture 3.

[0053] When the second electric cylinder 15 drives the blood collection needle assembly to move downward, the control system obtains the type of the blood collection needle according to the data of the visual camera 33. If the blood collection needle assembly is a blood collection needle that needs to be pressed, the second electric cylinder 15 drives the blood collection needle assembly to be directly pressed onto the syringe, thereby realizing the assembly of the syringe and the blood collection needle;

[0054] If the blood collection needle has threads and needs to be rotated and tightened, the control system controls the drive motor 21 to drive the rotating plate 22 to rotate, the rotating plate 22 drives the multiple clamping plates 23 to rotate, and the multiple clamping plates 23 drive the blood collection needle to rotate. After that, the second electric cylinder 15 drives the blood collection needle to move downward and tighten it with the syringe; the control system realizes the switching between press-fitting and tightening by controlling whether the drive motor 21 rotates.

[0055] When the rotating plate 22 drives the clamping plate 23 to rotate, the metal plate 262 in the clamping plate 23 cuts the magnetic flux lines in the magnetic field formed by multiple groups of magnets, and current is generated in the metal plate 262 and heat is generated. The metal plate 262 conducts the heat to the heat-conducting medium 261. At this time, the temperature sensor feeds back the temperature data of the heat-conducting medium 261 to the control system. The control system reduces the current passed into the heating wire 263 according to the temperature data of the heat-conducting medium 261, so that the heat generated by the heating wire 263 is reduced, thereby reducing energy consumption. When the temperature sensor detects that the heat generated by the metal plate 262 is low, the control system directly supplies power to the heating wire 263.

[0056] After the syringe and the blood collection needle are assembled into the finished product, the roller 42 in the unloading line 13 drives the transmission belt 41 to move, and the transmission belt 41 drives the fixture 3 and the assembled finished product to move forward. The staff removes the assembled finished product, and the first conveyor line 12 and the second conveyor line 14 convey another group of syringes and blood collection needles forward for re-assembly.
