[0039] like Figure 1 The figure shows a blood collection needle assembled by the automatic assembly device for venous blood collection needles with a safety seat of the present invention. The blood collection needle includes a needle body 910 and a safety seat 920. The needle body 910 includes a needle 911, a needle wing 912 and a needle tube 913. The middle part of the safety seat 920 is foldable and is provided with a hole for the needle 911 to pass through. The front and rear ends of the safety seat 920 are respectively provided with notches and protrusions. The needle body 910 has been assembled by other equipment. When assembling this equipment, after the needle 911 is inserted into the hole in the middle of the safety seat 920, the safety seat 920 is folded from the middle, and the notches and protrusions at the front and rear ends are buckled together. Then, hot pressing is performed to make the buckling more stable. Then, a test is performed to observe whether the assembly is qualified during the observation period. Finally, the assembled blood collection needle is unloaded. The specific scheme is described as follows.

[0040] An automatic assembly device for a venous blood collection needle with a safety seat includes a frame, a turntable 100, and a plurality of carriers 800 arranged on the turntable 100. A loading station 200, an assembly station 300, a pressing station 400, a heat sealing station 500, a testing station 600, and a discharging station 700 are sequentially arranged around the turntable 100 corresponding to the positions of the carriers 800. The turntable 100 is driven by a stepper motor, and a plurality of needle wing clips 810 are arranged on the carrier 800, and a card slot 820 is arranged between two needle wing clips 810.

[0041] The loading station 200 includes a loading channel 210 and a loading clamp. The safety seat 920 moves along the loading channel 210 to its end, and the loading clamp grabs the safety seat 920. When the carrier 800 rotates to the loading station 200, the loading clamp places the grabbed safety seat 920 in the slot 820, and the safety seat 920 is in an open state.

[0042] The assembly station 300 includes a first clamping portion 310 and a needle placement portion 330 .

[0043] The first clamping part 310 includes a first moving disk 312, a first clamping claw 311 disposed on the first moving disk 312, and a first cylinder 313 that drives the first moving disk 312 to move along the first clamping claw slide rail 315. A plurality of first clamping claws 311 are provided, and they are arranged in a straight line. In one embodiment, the first clamping claws 311 are provided in two rows, which are respectively used to clamp the head and tail ends of the needle 911, so that the clamping is more stable. Since the needle body 910 is relatively long as a whole, in one embodiment, the assembly station 300 also includes a second clamping part 320, and the second clamping part 320 includes a second moving disk 322 and a second clamping claw 321 disposed on the second moving disk 322, and also includes a second cylinder 323 that can drive the first moving disk 312 and the second moving disk 322 to move closer to or away from each other along the first clamping claw slide rail 315. In order to make the jaws move more flexibly, a third cylinder 314 is provided between the first movable plate 312 and the first jaw 311 ; a fourth cylinder 324 is provided between the second movable plate 322 and the second jaw 321 , so that the first jaw 311 and the second jaw 321 move in the vertical direction.

[0044] The needle body placement part 330 includes a discharge tray 331, a fifth cylinder 334 driving the discharge tray 331 to move along the needle body feeding slide rail 335, a first holder 332 and a second holder 333 arranged on the discharge tray 331, the first holder 332 is used to place the needle head 911 and the needle wing 912, and the second holder 333 is used to place the needle tube 913. The first holder 332 and the second holder 333 are evenly provided with grooves for placing the needle body 910. In order to make the needle body 910 more stable when placed on the needle body placement part 330, in one embodiment, two first holders 332 are provided, and the grooves of the two first holders 332 are correspondingly arranged, respectively used to place the head and tail ends of the needle head 911. Since the needle tube 913 is long, in one embodiment, the second holder 333 is also provided with two corresponding grooves, and the two second holders 333 are separated by a certain distance, so that the arrangement can prevent the needle tube from winding and affecting the feeding. In order to further make the needle 911 placed more stably, in one embodiment, a clamping portion 340 can also be provided. The clamping portion 340 includes a fixing clamp 341 and a sixth cylinder 342 that drives the fixing clamp 341 to rotate. The sixth cylinder 342 pushes one end of the fixing clamp 341, and the other end of the fixing clamp 341 is in a bent state and extends between the two first clamping seats 332. A protrusion is also provided between the two first clamping seats 332. The fixing clamp 341 cooperates with the protrusion to press the needle wing 912. The telescopic end of the sixth cylinder 342 pushes the fixing clamp 341 to rotate it, thereby pressing or releasing the needle wing 912.

[0045] The first clamping jaw 311 can clamp the needle 911 on the first clamping seat 332, and the second clamping jaw 321 can clamp the needle tube 913 on the second clamping seat 333. After clamping, the distance between the first clamping jaw 311 and the second clamping jaw 321 is adjusted by the second cylinder 323 to straighten the needle tube 913. At the same time, the first clamping jaw 311 is made close to the carrier 800 by the first cylinder 313, and the needle body 910 is placed on the carrier 800. Specifically, when the first clamping jaw 311 is close to the carrier 800, the needle wing clamp 810 is opened, the first clamping jaw 311 sends the needle 911 into the hole in the middle of the safety seat 920, and the needle wing 912 is placed on the needle wing clamp 810. After placement, the needle wing clamp 810 is closed to firmly clamp the needle wing 912, and the two wings of the needle wing 912 are clamped by two adjacent needle wing clamps 810 respectively.

[0046] The pressing station 400 is used to press the protrusion at one end of the safety seat 920 into the notch at the other end. When the carrier 800 moves to the pressing station 400, the pushing component on the carrier 800 pushes the upper part of the safety seat 920 so that the two ends thereof approach each other, and the pressing head and the pressing seat of the pressing station 400 approach each other, pressing the protrusion at one end of the safety seat 920 into the notch at the other end.

[0047] The heat sealing station 500 includes an upper heat sealing portion 510 and a lower heat sealing portion 520 .

[0048] The upper heat-sealing unit 510 includes a heat pressing head 511 and a first upper clamping seat 512 .

[0049] The lower heat-sealing part 520 includes a heat-pressing platform 521, a first lower clamping seat 522 elastically connected to the heat-pressing platform 521, a heat-sealing frame 523, a seventh cylinder 524 arranged on the heat-sealing frame 523 and capable of driving the heat-pressing platform 521 to move, an eighth cylinder 525 capable of driving the heat-sealing frame 523 to move along the heat-sealing slide rail 526, a guide wheel 528 elastically connected to the heat-pressing platform 521, and a limit plate 529 fixed to the frame. The first lower clamping seat 522 is fixedly connected to the guide wheel 528, and the first lower clamping seat 522 and the guide wheel 528 are elastically connected to the heat-pressing platform 521 through a spring 527. The end of the limit plate 529 is inclined, and the guide wheel 528 can roll along the edge of the limit plate 529.

[0050] When the carrier 800 moves to the heat-sealing station 500, driven by the eighth cylinder 525, the heat-pressing platform 521 and the first lower clamping seat 522 move synchronously to the bottom of the heat-pressing head 511 and the first upper clamping seat 512. Driven by the cylinder, the first lower clamping seat 522 and the first upper clamping seat 512 are close to each other, and the first lower clamping seat 522 and the first upper clamping seat 512 are both provided with a plurality of corresponding grooves. When the two are close to each other, the safety seat 920 can be clamped in the corresponding grooves so that it will not shake during heat pressing. At the same time, the heat-pressing platform 521 and the heat-pressing head 511 are close to each other, and the notches and protrusions of the safety seat 920 that are buckled with each other are heated by heat pressing, and then further locked.

[0051] The inspection station 600 includes an inspection component 610 and a fixing component 620 .

[0052] The detection assembly 610 includes a detection conveyor belt 613, an industrial camera 611 disposed on the detection conveyor belt 613, and a first motor 612 for driving the detection conveyor belt 613 to move back and forth. In order to make the industrial camera 611 take clearer pictures and ensure accurate detection, a light source 615 can be added around the industrial camera 611 to adjust the illumination of the detection environment. The industrial camera 611 moves along the conveying slide rail 614 on the detection conveyor belt 613.

[0053] The fixing assembly 620 includes a second upper clamping seat 621 , a second lower clamping seat 622 cooperating with the second upper clamping seat 621 , a detection frame 623 , and a ninth cylinder 624 driving the detection frame 623 to move along the detection slide rail 625 . The second lower clamping seat 622 and the detection frame 623 are connected via a tenth cylinder 626 .

[0054] When the carrier 800 moves to the inspection station 600, driven by the ninth cylinder 624, the second lower clamping seat 622 moves to the bottom of the second upper clamping seat 621. Driven by the cylinder, the second lower clamping seat 622 and the second upper clamping seat 621 approach each other. Similarly, a number of corresponding grooves are also provided on the second lower clamping seat 622 and the second upper clamping seat 621. After the two are close, the safety seat 920 can be clamped in the corresponding groove so that it will not shake during inspection. The position where the safety seat 920 is clamped by the second lower clamping seat 622 and the second upper clamping seat 621 is just within the detection range of the industrial camera 611. The industrial camera 611 moves under the drive of the first motor 612 to detect whether each safety seat 920 on the carrier 800 is buckled properly.

The unloading tray 711 on the unloading conveyor belt 713 is driven by the second motor 712, and the unloading slide rail 714 moves. Since the blood collection needles are relatively long as a whole, in order to prevent the blood collection needles from being stacked in a disorderly manner and entangled with each other during unloading, in one embodiment, a fourth clamping jaw 716 is further provided. The third clamping jaw 715 is connected to the fourth clamping jaw 716 through a clamping jaw cylinder 718. The fourth clamping jaw 716 moves along the second clamping jaw slide rail 719 and is driven by the clamping jaw cylinder 718 to approach or move away from the third clamping jaw 715. In order to clamp the blood collection needle more stably, in one embodiment, the third clamping jaws 715 are arranged in two rows, respectively used to clamp the needle 911 and the safety seat 920. The fourth clamping jaws 716 are also arranged in two rows, both used to hold the needle tube 913.

[0057] The lifting part 720 includes a lifting base 721 , a lifting frame 722 , and a twelfth cylinder 723 for driving the lifting frame 722 to move along a lifting slide rail 724 . The lifting base 721 and the lifting frame 722 are connected via a lifting cylinder 726 .

[0058] When the carrier 800 moves to the unloading station 700, driven by the twelfth cylinder 723 and the lifting cylinder 726, the lifting seat 721 lifts the needle tube 913 on the carrier 800 and moves it to the bottom of the fourth clamp 716. The third clamp 715 and the fourth clamp 716 move downward under the drive of the eleventh cylinder 717, and respectively grab the needle 911, the safety seat 920 and the needle tube 913 of the blood collection needle. Then the telescopic end of the eleventh cylinder 717 retracts, and the third clamp 715 and the fourth clamp 716 move upward. Driven by the clamp cylinder 718, the fourth clamp 716 moves away from the third clamp 715, so that the needle tube 913 is horizontally straightened. At the same time, driven by the second motor 712, the unloading tray 711 drives the third clamp 715 and the fourth clamp 716 to move away from the turntable 100, and after moving to the top of the discharge position, the blood collection needle is released.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
