[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The principles and features of the present invention are described, and the examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0039] like Figure 1 The image shows a blood collection needle assembled by the automatic assembly device for venous blood collection needles with a safety seat according to the present invention. The needle includes a needle body 910 and a safety seat 920. The needle body 910 includes a needle tip 911, needle wings 912, and a needle tube 913. The safety seat 920 is foldable in the middle and has a hole for the needle tip 911 to pass through. The front and rear ends of the safety seat 920 are respectively provided with slots and protrusions. The needle body 910 has already been assembled by other equipment. During assembly in this device, after the needle tip 911 is inserted into the hole in the middle of the safety seat 920, the safety seat 920 folds from the middle, and the slots and protrusions at its front and rear ends snap together. Heat pressing is then used to make the snap-fit more secure. Afterwards, an inspection period is conducted to check if the assembly is qualified. Finally, the assembled blood collection needle is unloaded. The specific scheme is described below.
[0040] An automated assembly device for venous blood collection needles with a safety seat includes a frame, a turntable 100, and several carriers 800 mounted on the turntable 100. Around the turntable 100 are sequentially arranged a loading station 200, an assembly station 300, a pressing station 400, a heat sealing station 500, a testing station 600, and an unloading station 700, each corresponding to a position on a carrier 800. The turntable 100 is driven by a stepper motor. Several needle clips 810 are mounted on the carriers 800, and slots 820 are provided between two needle clips 810.
[0041] The loading station 200 includes a loading channel 210 and a loading gripper. The safety seat 920 moves along the loading channel 210 to its end, and the loading gripper grabs the safety seat 920. When the carrier 800 rotates to the loading station 200, the loading gripper places the grabbed safety seat 920 into the slot 820, at which time the safety seat 920 is in an open state.
[0042] The assembly station 300 includes a first clamping part 310 and a needle placement part 330.
[0043] The first gripping part 310 includes a first movable disk 312, first grippers 311 disposed on the first movable disk 312, and a first cylinder 313 that drives the first movable disk 312 to move along the first gripper slide rail 315. Several first grippers 311 are provided and arranged in a straight line. In one embodiment, the first grippers 311 are arranged in two rows, respectively used to grip the beginning and end ends of the needle tip 911, making the gripping more stable. Since the needle body 910 is relatively long, in one embodiment, the assembly station 300 also includes a second gripping part 320. The second gripping part 320 includes a second movable disk 322 and second grippers 321 disposed on the second movable disk 322, and also includes a second cylinder 323 capable of driving the first movable disk 312 and the second movable disk 322 to move closer to or further away from each other along the first gripper slide rail 315. To make the gripper move more flexibly, a third cylinder 314 is provided between the first moving disk 312 and the first gripper 311; a fourth cylinder 324 is provided between the second moving disk 322 and the second gripper 321, so that the first gripper 311 and the second gripper 321 can move in the vertical direction.
[0044] The needle placement section 330 includes a feeding tray 331, a fifth cylinder 334 that drives the feeding tray 331 to move along the needle feeding slide rail 335, a first retainer 332 and a second retainer 333 disposed on the feeding tray 331. The first retainer 332 is used to place the needle tip 911 and needle wing 912, and the second retainer 333 is used to place the needle tube 913. The first retainer 332 and the second retainer 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 placement section 330, in one embodiment, two first retainers 332 are provided, and the grooves of the two first retainers 332 are correspondingly arranged to place the head and tail ends of the needle tip 911 respectively. Since the needle tube 913 is relatively long, in one embodiment, the second retainer 333 is also provided with two corresponding grooves, and the two second retainers 333 are separated by a certain distance. This arrangement can prevent the needle tube from tangling and affecting the feeding. To further ensure a more stable placement of the needle 911, in one embodiment, a clamping part 340 may be provided. The clamping part 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 bent and extends between two first card seats 332. A protrusion is also provided between the two first card seats 332. The fixing clamp 341 cooperates with the protrusion to press down the needle wing 912. The telescopic end of the sixth cylinder 342 pushes the fixing clamp 341 to rotate, which can press down or release the needle wing 912.
[0045] The first gripper 311 can grip the needle 911 on the first chuck 332, and the second gripper 321 can grip the needle tube 913 on the second chuck 333. After gripping, the distance between the first gripper 311 and the second gripper 321 is adjusted by the second cylinder 323 to straighten the needle tube 913. At the same time, the first cylinder 313 moves the first gripper 311 closer to the carrier 800 and places the needle body 910 on the carrier 800. Specifically, when the first gripper 311 approaches the carrier 800, the needle wing clamp 810 opens, and the first gripper 311 sends the needle 911 into the hole in the middle of the safety seat 920 and places the needle wing 912 on the needle wing clamp 810. After placement, the needle wing clamp 810 closes, firmly clamping the needle wing 912. 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 groove 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 its two ends are close to each other. The pressing head and pressing seat of the pressing station 400 are close to each other, pressing the protrusion at one end of the safety seat 920 into the groove at the other end.
[0047] The heat sealing station 500 includes an upper heat sealing part 510 and a lower heat sealing part 520.
[0048] The upper heat sealing part 510 includes a heat pressing head 511 and a first upper card holder 512.
[0049] The lower heat-sealing section 520 includes a heat-pressing platform 521, a first lower retainer 522 elastically connected to the heat-pressing platform 521, a heat-sealing frame 523, a seventh cylinder 524 mounted 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 limiting plate 529 fixed to the frame. The first lower retainer 522 is fixedly connected to the guide wheel 528, and the first lower retainer 522 and the guide wheel 528 are elastically connected to the heat-pressing platform 521 through a spring 527. The end of the limiting plate 529 is inclined, and the guide wheel 528 can roll along the edge of the limiting plate 529.
[0050] When the carrier 800 moves to the heat sealing station 500, driven by the eighth cylinder 525, the hot pressing platform 521 and the first lower clamping seat 522 move synchronously below the hot 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 move closer to each other, and both the first lower clamping seat 522 and the first upper clamping seat 512 are provided with several corresponding grooves. When they move closer to each other, the safety seat 920 can be locked in the corresponding grooves, so that it will not shake during hot pressing. At the same time, the hot pressing platform 521 and the hot pressing head 511 move closer to each other, and by using hot pressing, the interlocking slots and protrusions of the safety seat 920 are heated, thereby further locking.
[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 mounted on the detection conveyor belt 613, and a first motor 612 that drives the detection conveyor belt 613 to reciprocate. To make the images captured by the industrial camera 611 clearer and ensure detection accuracy, a light source 615 can be added around the industrial camera 611 to adjust the ambient light level. The industrial camera 611 moves along the conveyor rail 614 on the detection conveyor belt 613.
[0053] The fixing assembly 620 includes a second upper bracket 621, a second lower bracket 622 that cooperates with the second upper bracket 621, a detection frame 623, and a ninth cylinder 624 that drives the detection frame 623 to move along the detection slide rail 625. The second lower bracket 622 and the detection frame 623 are connected by a tenth cylinder 626.
[0054] When the carrier 800 moves to the inspection station 600, driven by the ninth cylinder 624, the second lower clamp 622 moves below the second upper clamp 621. Driven by the cylinder, the second lower clamp 622 and the second upper clamp 621 move closer to each other. Similarly, the second lower clamp 622 and the second upper clamp 621 are also provided with several corresponding grooves. After they move closer, 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 clamp 622 and the second upper clamp 621 is exactly within the inspection range of the industrial camera 611. The industrial camera 611 moves under the drive of the first motor 612 and sequentially inspects whether each safety seat 920 on the carrier 800 is properly clamped.
[0055] The unloading station 700 includes an unloading clamping part 710 and a lifting part 720.
[0056] The unloading clamping unit 710 includes an unloading conveyor belt 713, an unloading disc 711 disposed on the unloading conveyor belt 713, a second motor 712 driving the unloading conveyor belt 713 to reciprocate, and a third gripper 715. The third gripper 715 is connected to the unloading disc 711 via an eleventh cylinder 717. Driven by the second motor 712, the unloading disc 711 on the unloading conveyor belt 713 moves along the unloading slide rail 714. Since the blood collection needles are relatively long, to prevent them from being stacked haphazardly or tangled during unloading, in one embodiment, a fourth gripper 716 is also provided. The third gripper 715 and the fourth gripper 716 are movably connected via a gripper cylinder 718. The fourth gripper 716 moves along the second gripper slide rail 719 under the drive of the gripper cylinder 718, moving closer to or further away from the third gripper 715. To ensure a more secure gripping of the blood collection needle, in one embodiment, the third gripper 715 is provided in two rows, respectively for gripping the needle tip 911 and the safety seat 920. The fourth gripper 716 is also provided in two rows, both for holding the needle tube 913.
[0057] The lifting unit 720 includes a lifting bracket 721, a lifting frame 722, and a twelfth cylinder 723 that drives the lifting frame 722 to move along the lifting slide rail 724. The lifting bracket 721 and the lifting frame 722 are connected by the 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 holder 721 lifts the needle 913 on the carrier 800 and moves it below the fourth gripper 716. Driven by the eleventh cylinder 717, the third gripper 715 and the fourth gripper 716 move downwards, respectively gripping the needle tip 911, the safety seat 920, and the needle tube 913 of the blood collection needle. Then, the extension end of the eleventh cylinder 717 retracts, and the third gripper 715 and the fourth gripper 716 move upwards. Driven by the gripper cylinder 718, the fourth gripper 716 moves away from the third gripper 715, causing the needle tube 913 to extend horizontally. Simultaneously, driven by the second motor 712, the unloading disc 711 moves the third gripper 715 and the fourth gripper 716 away from the turntable 100. After moving above the discharge point, 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
