[0015] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figure 1-27 As shown, a peripheral blood collection needle packaging device includes a machine base 100 and a controller. The machine base 100 is equipped with a blood collection needle feeding mechanism 300, a blood collection needle conveying and transfer mechanism 400, a paper box feeding and forming mechanism 500, a paper box conveyor belt 600, a blood collection needle boxing mechanism 700, and a lid unloading mechanism 800, all of which are connected to the controller.

[0017] like Figure 1 As shown, a protective cover 900 is also installed on the machine 100. The protective cover 900 is fitted around the blood collection needle feeding mechanism 300, the blood collection needle conveying and transfer mechanism 400, the cardboard box feeding and forming mechanism 500, the cardboard box conveyor belt 600, the blood collection needle boxing mechanism 700, and the lid unloading mechanism 800. The protective cover 900 provides protection, improves processing safety, and reduces the entry of dust and other contaminants into the equipment. Multiple openable protective doors 910 are installed on the protective cover 900, allowing for convenient maintenance and debugging of the equipment. An alarm light 110 connected to the controller is installed at the top of the protective cover 900. When the equipment malfunctions, the controller will activate the alarm light 110 to alert the operator to take timely action. The controller includes a display screen 120 and multiple control buttons 130 mounted on the side wall of the protective cover 900. The display screen 120 can be used to display information such as the working parameters of the equipment, and can also be used by operators to debug the working parameters of the equipment. The control buttons 130 can be used to debug and control the operation of the equipment.

[0018] The blood collection needle feeding mechanism 300 is connected to the blood collection needle conveying and transfer mechanism 400, and is used to orderly convey blood collection needles to the blood collection needle conveying and transfer mechanism 400. The feeding machine or manual feeding will convey the blood collection needles to the blood collection needle feeding mechanism 300. The blood collection needle feeding mechanism 300 can orderly convey the blood collection needles to the blood collection needle conveying and transfer mechanism 400 in a uniform direction, thus completing the feeding action of the blood collection needles.

[0019] The blood collection needle conveying and transfer mechanism 400 is connected to the blood collection needle feeding mechanism 300 and the blood collection needle boxing mechanism 700 respectively. It is used to convey and transfer the blood collection needles to the processing position of the blood collection needle boxing mechanism 700 and place the blood collection needles on the blood collection needle boxing mechanism 700 according to the preset boxing interval.

[0020] The cardboard box feeding and forming mechanism 500 is connected to the cardboard box conveyor belt 600, and is used to fold and form the cardboard box and place the formed cardboard box onto the cardboard box conveyor belt 600. The cardboard box conveyor belt 600 is connected to the cardboard box feeding and forming mechanism 500, the lancet box packing mechanism 700, and the lid box unloading mechanism 800. The cardboard box conveyor belt 600 can transport the formed empty cardboard boxes to the processing position of the lancet box packing mechanism 700, and transport the cardboard boxes with lancets inside to the lid box unloading mechanism 800.

[0021] The blood collection needle boxing mechanism 700 is used to feed the blood collection needles into the formed paper box on the paper box conveyor belt 600, and the box closing and unloading mechanism 800 is used to close the paper box containing the blood collection needles and send it out of the machine 100.

[0022] This terminal blood collection needle packaging equipment, through the coordinated operation of the blood collection needle feeding mechanism 300, the blood collection needle conveying and transfer mechanism 400, the cardboard box feeding and forming mechanism 500, the blood collection needle boxing mechanism 700, and the box lid unloading mechanism 800, can achieve full automation from blood collection needle feeding and cardboard box forming to blood collection needle boxing, box lidding and unloading, without manual intervention, significantly improving the packaging efficiency of blood collection needles and reducing labor costs.

[0023] like Figure 4-8 As shown, the blood collection needle feeding mechanism 300 includes a feeding component 310, a detection component 320, and a picking component 330, all connected to the machine base 100. The feeding component 310 receives blood collection needles to be packaged and sequentially transports them to the picking position of the picking component 330. During processing, the blood collection needles are fed onto the feeding component 310 by a feeding machine or manually, and then sequentially transported to the picking position of the picking component 330 by the feeding component 310.

[0024] The detection component 320 is positioned at a corresponding location on the feeding component 310 to photograph the blood collection needles on the feeding component 310, thereby obtaining the orientation of the blood collection needles on the feeding component 310. The picking component 330 is connected to both the feeding component 310 and the blood collection needle conveying and transfer mechanism 400, and is used to pick up the blood collection needles from the feeding component 310 and place them on the blood collection needle conveying and transfer mechanism 400. The picking component 330 is equipped with a turning mechanism, which drives the blood collection needles to change direction, so that the picking component 330 can place all the blood collection needles on the blood collection needle conveying and transfer mechanism 400 in the same direction, ensuring that the feeding direction is consistent.

[0025] During processing, blood collection needles are fed onto the feeding assembly 310 via a feeding machine or manually. The feeding assembly 310 then sequentially feeds the blood collection needles to the gripping position of the picking assembly 330. While the feeding assembly 310 feeds the blood collection needles to the picking assembly 330, the detection assembly 320 takes pictures of each blood collection needle on the feeding assembly 310. After the feeding assembly 310 feeds the blood collection needles to the gripping position of the picking assembly 330, the picking assembly 330 picks up each blood collection needle from the feeding assembly 310. Based on the images of the blood collection needles taken by the detection assembly 320, it determines whether the current direction of the blood collection needle is consistent with the feeding direction. If they are inconsistent, the picking mechanism drives the blood collection needles to change direction. When the direction of all the blood collection needles picked up by the picking assembly 330 is consistent with the feeding direction, the picking assembly 330 places the blood collection needles onto the blood collection needle conveying and transfer mechanism 400, completing the blood collection needle feeding process.

[0026] like Figure 5As shown, the feeding assembly 310 includes a receiving box 311 and a direct vibration module 312, which are respectively connected to the machine base 100. The output end of the direct vibration module 312 is equipped with a feeding guide rail 313, one end of which extends into the receiving box 311, and the other end is connected to the picking assembly 330. The feeding guide rail 313 is equipped with a guide groove 314, which is used to accommodate and guide the blood collection needles. During operation, the feeding machine or a person pours the blood collection needles into the receiving box 311. The blood collection needles automatically fall into the guide groove 314 on the feeding guide rail 313. Then, the direct vibration module 312 drives the blood collection needles to move forward within the guide groove 314, thereby conveying the blood collection needles to the gripping position of the picking assembly 330.

[0027] To ensure the blood collection needles in the receiving box 311 can smoothly fall into the guide groove 314, in this embodiment, a guide motor 315 is provided on the receiving box 311. A rotating shaft 316 is connected to the output end of the guide motor 315, extending into and rotatably connecting to the receiving box 311. Guide blades 317 are provided on the rotating shaft 316, used to push the blood collection needles into the guide groove 314. The guide blades 317 can be made of flexible materials such as silicone to prevent the guide blades 317 from damaging the blood collection needles. After the blood collection needle is tilted into the receiving box 311, the guide motor 315 starts to work and drives the rotating shaft 316 and the guide blade 317 to rotate. The guide blade 317 pushes the blood collection needle in the receiving box 311, causing it to fall into the guide groove 314. Then, in conjunction with the direct vibration module 312, the blood collection needle is driven to be transported to the gripping position of the picking component 330.

[0028] The direct vibration module 312 can be any existing type, and this utility model does not limit it.

[0029] Preferably, there are two linear vibration modules 312 and two feeding guide rails 313, and each feeding guide rail 313 is provided with five feeding grooves 314. This design can process ten blood collection needles at the same time, greatly improving the feeding efficiency.

[0030] like Figure 6As shown, the detection assembly 320 includes a detection mounting frame 321, which is connected to the machine base 100. The detection mounting frame 321 is equipped with a detection camera 322 and a supplementary light source 323, which are located above the feeding guide rail 313. The detection camera 322 is used to photograph the blood collection needles inside the feed trough 314, and the supplementary light source 323 is used to illuminate the blood collection needles inside the feeding guide rail 313 so that the detection camera 322 can obtain clear images. During operation, the linear vibration module 312 operates, driving the blood collection needle to move linearly on the feeding guide rail 313. When the blood collection needle moves below the detection camera 322, the supplementary light source 323 illuminates the blood collection needle on the feeding guide rail 313, and then the detection camera 322 takes a picture of the blood collection needle to obtain a clear image of the blood collection needle in the feeding groove 314. The image is then sent to the controller, which can determine whether the direction of the blood collection needle in the feeding groove 314 is consistent with the preset feeding direction by comparison.

[0031] In this embodiment, there are two detection cameras 322 and two supplementary light sources 323, and they are configured in a one-to-one correspondence. By setting two detection cameras 322, the blood collection needles in the ten guide slots 314 on the two feeding guide rails 313 can be detected simultaneously, improving efficiency.

[0032] like Figure 7 As shown, the material handling assembly 330 includes a material handling fixing frame 331, which is connected to the machine base 100. A material handling transverse movement module 332 is mounted on the material handling fixing frame 331, and a material handling lifting module 333 is mounted on the output end of the material handling transverse movement module 332. Both the material handling transverse movement module 332 and the material handling lifting module 333 can employ any existing linear drive device, such as a cylinder module, an electric cylinder module, or a motor lead screw module; the specific structure is not limited in this invention. A steering mechanism is connected to the output end of the material handling lifting module 333, and a material handling gripper cylinder 334 is mounted on the output end of the steering mechanism. During operation, the material handling transverse module 332 and the material handling lifting module 333 work together to drive the material handling gripper cylinder 334 to the end of the loading guide rail 313. The material handling gripper cylinder 334 then picks up the blood collection needle from the loading guide rail 313. Next, the material handling transverse module 332 and the material handling lifting module 333 work together to drive the material handling gripper cylinder 334 to the loading position of the blood collection needle conveying and transfer mechanism 400, after which the material handling gripper cylinder 334 releases the blood collection needle. This process transfers the blood collection needle from the loading guide rail 313 to the blood collection needle conveying and transfer mechanism 400.

[0033] Specifically, the steering mechanism includes a rotary cylinder 335, which is connected to the output end of the material handling and lifting module 333, and a material handling gripper cylinder 334 is connected to the output end of the rotary cylinder 335. During processing, if the detection camera 322 captures images of a blood collection needle in a certain guide groove 314 with the opposite direction, the material handling gripper cylinder 334 picks up the blood collection needle and then controls the corresponding rotary cylinder 335 to work, driving the material handling gripper cylinder 334 to rotate the blood collection needle 180°, thereby reversing the direction of the blood collection needle and achieving the purpose of turning the feeding direction of the blood collection needle.

[0034] In addition, such as Figure 4 , Figure 8 As shown, the machine 100 is also equipped with a material shortage detection mechanism 340, which is located between the receiving box 311 and the material handling component 330. This mechanism is used to detect whether there are blood collection needles in the guide trough 314. By setting up the material shortage detection mechanism 340, it is possible to monitor in real time whether there are blood collection needles in the guide trough 314, avoiding empty grabbing and improving the stability and reliability of the feeding process.

[0035] Specifically, the material shortage detection mechanism 340 includes a material shortage mounting frame 341, which is connected to the machine base 100. The mounting frame 341 is equipped with a mounting rod 342, positioned above the feeding guide rail 313. Material shortage sensors 343 are respectively installed on the mounting rod 342 at corresponding positions to the guide trough 314. The material shortage sensors 343 can detect in real time whether there are blood collection needles in the corresponding guide trough 314. If a material shortage sensor 343 detects that there is no product in the guide trough 314, it sends a signal to remind the operator to replenish the blood collection needles in the receiving box 311 in a timely manner, avoiding idle operation and improving equipment utilization.

[0036] The blood collection needle feeding mechanism 300, through the coordinated work of the feeding component 310, the detection component 320 and the picking component 330, realizes automatic feeding, direction detection and direction adjustment of blood collection needles, ensuring that all blood collection needles are transported to the cartoning station in a uniform direction, which greatly improves cartoning efficiency and product consistency.

[0037] like Figure 9-12 As shown, the blood collection needle conveying and transfer mechanism 400 includes a feeding conveyor belt 410 and a picking-up distance adjustment mechanism 420. The feeding conveyor belt 410 is connected to the blood collection needle feeding mechanism 300 and the picking-up distance adjustment mechanism 420 respectively, and is used to sequentially convey blood collection needles to the picking-up distance adjustment mechanism 420; the picking-up distance adjustment mechanism 420 is used to pick up blood collection needles from the feeding conveyor belt 410 and place the blood collection needles on the blood collection needle boxing mechanism 700 at a preset interval.

[0038] During operation, the blood collection needle feeding mechanism 300 places the blood collection needles onto the feeding conveyor belt 410, which then transports them sequentially to the processing position of the picking and adjusting mechanism 420. The picking and adjusting mechanism 420 then picks up the blood collection needles from the feeding conveyor belt 410, adjusts the spacing between the needles, and places them onto the blood collection needle boxing mechanism 700, thus achieving an automatic transfer process for the blood collection needles.

[0039] like Figure 10 As shown, the feeding conveyor belt 410 includes a conveyor belt mounting frame 411, which is fixedly connected to the machine base 100. A conveyor drive motor 412, a drive wheel 413, and a driven wheel 414 are mounted on the conveyor belt mounting frame 411. The drive wheel 413 and the driven wheel 414 are rotatably connected to the conveyor belt mounting frame 411 via bearings. The output end of the conveyor drive motor 412 is connected to the drive wheel 413 via a coupling. A conveyor belt 415 is fitted onto the drive wheel 413 and the driven wheel 414. Multiple limiting blocks 416 are fixed at equal intervals on the conveyor belt 415, forming a product limiting groove 417 between adjacent limiting blocks 416 to accommodate a single blood collection needle. During operation, the conveyor drive motor 412 drives the drive wheel 413 to rotate, which in turn drives the driven wheel 414 to rotate synchronously via the conveyor belt 415, achieving a step-by-step conveying of the blood collection needle.

[0040] like Figure 11 As shown, the material handling and pitch-changing mechanism 420 includes a gripping mounting frame 421, which is fixedly connected to the machine base 100. A gripping lateral movement module 422 is mounted on the gripping mounting frame 421, and a gripping lifting module 423 is fixedly mounted on the output end of the gripping lateral movement module 422. Both the gripping lateral movement module 422 and the gripping lifting module 423 can be any existing linear module, such as a cylinder, electric cylinder, motor screw module, or synchronous belt module. A pitch-changing mechanism 430 is connected to the output end of the gripping lifting module 423. Multiple gripping suction cups 424 are provided on the output end of the pitch-changing mechanism 430. Each gripping suction cup 424 is externally connected to a negative pressure device. The pitch-changing mechanism 430 is used to adjust the distance between the blood collection needles.

[0041] When a blood collection needle needs to be grasped, the gripping lateral movement module 422 and the gripping lifting module 423 work together to drive the gripping suction cup 424 to move to the corresponding position on the feeding conveyor belt 410, so that the gripping suction cup 424 contacts the blood collection needles in each product limiting groove 417. Then, the external negative pressure device is controlled to work, so that the gripping suction cup 424 generates negative pressure suction to attract each blood collection needle. Then, the gripping lifting module 423 drives the gripping suction cup 424 to rise and remove the blood collection needles from the product limiting grooves 417. Then, the pitch mechanism 430 adjusts the spacing between the blood collection needles so that the spacing between the blood collection needles is adapted to the blood collection needle boxing mechanism 700. Then, through the coordinated action of the gripping transverse module 422 and the gripping lifting module 423, the gripping suction cup 424 is driven to move the blood collection needle to the receiving position of the blood collection needle boxing mechanism 700. Then, the external negative pressure device is controlled to release the negative pressure, so that the gripping suction cup 424 releases the blood collection needle onto the blood collection needle boxing mechanism 700, thus completing the variable-distance transfer of the blood collection needle.

[0042] like Figure 12 As shown, the pitch-changing mechanism 430 includes a pitch-changing fixing frame 431, which is fixedly connected to the output end of the gripping and lifting module 423. A pitch-changing drive component 432 (which can be a cylinder or an electric push rod) and two parallel transverse guide rods 433 are mounted on the pitch-changing fixing frame 431. Ten suction cup mounting rods 434 are slidably sleeved on the transverse guide rods 433. Two gripping suction cups 424 are mounted at the end of each suction cup mounting rod 434, and the gripping suction cups 424 are connected to an external negative pressure device (such as a vacuum generator) via air pipes. A rolling bearing 435 is also mounted on each suction cup mounting rod 434. A pitch-changing lifting plate 436 is connected to the output end of the pitch-changing drive component 432. Ten oblique guide grooves 437, corresponding one-to-one with the suction cup mounting rods 434, are provided on the pitch-changing lifting plate 436. The roller portion of the rolling bearing 435 extends into the corresponding inclined guide groove 437 and can roll along the inclined guide groove 437.

[0043] When a pitch change is required, the pitch changer drive 432 drives the pitch changer lifting plate 436 to move up and down, causing the rolling bearing 435 to roll in the inclined guide groove 437, thereby driving the suction cup mounting rod 434 to slide laterally on the transverse guide rod 433. The suction cup mounting rod 434 drives the gripping suction cup 424 to move synchronously, thereby achieving the purpose of adjusting the distance between the gripping suction cups 424.

[0044] To ensure the smooth movement of the variable pitch lifting plate 436, two lifting guide rods 438 are fixed on the variable pitch fixing frame 431, and corresponding lifting guide sleeves 439 are installed on the variable pitch lifting plate 436. The lifting guide rods 438 pass through the corresponding lifting guide sleeves 439, and the two slide in cooperation. Through the cooperation of the lifting guide rods 438 and the lifting guide sleeves 439, the movement direction of the variable pitch lifting plate 436 can be limited and guided, improving the accuracy and stability of the transmission.

[0045] In other embodiments, the number of suction cup mounting rods 434 can be any other number, and each suction cup mounting rod 434 can also be provided with other numbers of gripping suction cups 424.

[0046] During processing, the blood collection needle feeding mechanism 300 will place the blood collection needles sequentially into the product limiting groove 417 of the feeding conveyor belt 410. The conveyor drive motor 412 starts, driving the conveyor belt 415 to move intermittently, gradually conveying the blood collection needles to the gripping station below the material handling variable pitch mechanism 420.

[0047] Then, the gripping lateral movement module 422 drives the gripping lifting module 423 and the pitch-changing mechanism to move above the gripping station. Subsequently, the gripping lifting module 423 drives the pitch-changing mechanism 430 to descend, so that all the gripping suction cups 424 respectively connect with the corresponding blood collection needles. Then, the negative pressure device operates, and the gripping suction cups 424 adsorb the blood collection needles. Then, the gripping lifting module 423 rises, and the gripping lateral movement module 422 moves the pitch-changing mechanism 430 to the receiving position of the blood collection needle boxing mechanism 700.

[0048] During the movement or after reaching the unloading station, the variable pitch lifting plate 436 is driven to descend by the variable pitch drive component 432. Since the rolling bearing 435 is engaged within the inclined guide groove 437, the descent of the variable pitch lifting plate 436 is transformed by the inclined surface of the inclined guide groove 437 into the lateral sliding of the suction cup mounting rod 434 on the transverse guide rod 433, thereby changing the spacing between all the gripping suction cups 424. After adjustment, the gripping lifting module 423 descends, the negative pressure is released, and the blood collection needle is precisely placed into the receiving position of the blood collection needle packaging mechanism 700. This completes the transfer and spacing adjustment of the blood collection needle.

[0049] like Figure 13-18 As shown, the paper box feeding and forming mechanism 500 includes an operating table 510, a paper box stacking mechanism 520, a paper box picking mechanism 530, and a paper box feeding robot 540, which are respectively installed on the machine base 100. The paper box stacking mechanism 520 is located above the operating table 510, and the paper box picking mechanism 530 is located below the operating table 510. The operating table 510 is provided with a bottom forming mechanism 550. The paper box stacking mechanism 520 is used to stack paper boxes to be formed. The paper box taking mechanism 530 is connected to the paper box stacking mechanism 520 and the operating table 510 respectively. It is used to take out paper boxes from the paper box stacking mechanism 520 and can transport the pre-formed paper boxes to the position on the operating table 510 corresponding to the bottom forming mechanism 550. The bottom forming mechanism 550 is used to perform bottom forming on the paper boxes on the operating table 510. The paper box feeding robot 540 is connected to the operating table 510 and the paper box conveyor belt 600 respectively. It is used to take the formed paper boxes from the operating table 510 and place them on the paper box conveyor belt 600.

[0050] Before processing, the operator stacks the cardboard boxes onto the cardboard box stacking mechanism 520. During processing, the bottom cardboard box is first removed from the stacking mechanism 520 by the cardboard box picking mechanism 530. During the picking process, the cardboard box is pre-deformed along the pre-fold position, so that the four side walls of the cardboard box form a parallelogram. After the cardboard box is removed by the cardboard box picking mechanism 530, it is transported to the operating table 510 at the position corresponding to the bottom forming mechanism 550. Then, the bottom forming mechanism 550 forms the bottom of the cardboard box, so that the cardboard box is fully formed. After the cardboard box is formed, it is removed from the operating table 510 by the cardboard box feeding robot 540 and placed on the cardboard box conveyor belt 600. This completes the cardboard box forming and feeding process.

[0051] like Figure 15 As shown, the cardboard box stacking mechanism 520 includes a cardboard box stacking frame 521, which is fixedly connected to the machine base 100. Multiple cardboard box limiting rods 522 are vertically installed on the cardboard box stacking frame 521. These limiting rods 522 allow cardboard boxes to be stacked and placed on the cardboard box stacking frame 521, preventing cardboard box displacement and improving the stability of the feeding process. The lower surface of the cardboard box stacking frame 521 has a hollow structure, facilitating the cardboard box picking mechanism 530 to pick up materials from below the cardboard box stacking frame 521. A cardboard box limiting block 523 is provided on the lower side of the cardboard box stacking frame 521 to prevent cardboard boxes from falling out of the cardboard box stacking frame 521.

[0052] like Figure 16 As shown, the paper box picking mechanism 530 includes a conveying cylinder 531, which is connected to the machine base 100. The output end of the conveying cylinder 531 is provided with a paper box picking mounting block 532, the paper box picking mounting block 532 is provided with a paper box picking cylinder 533, the output end of the paper box picking cylinder 533 is provided with a suction cup fixing block 534, the suction cup fixing block 534 is provided with a paper box picking suction cup 535, the operating table 510 is provided with a hollow guide groove 511, the paper box picking suction cup 535 passes through the hollow guide groove 511, the paper box picking suction cup 535 is connected to a negative pressure device, and the paper box picking cylinder 533 can drive the paper box picking suction cup 535 to extend into or out of the paper box stacking mechanism 520.

[0053] In the initial state, the cardboard box is placed on the cardboard box stacking rack 521, and the cardboard box is limited by the cardboard box limiting block 523 to prevent it from falling out of the cardboard box stacking rack 521. When picking up the cardboard box, the cardboard box picking cylinder 533 drives the cardboard box picking suction cup 535 to move upward, so that the cardboard box suction cup passes through the hollow guide groove 511 and extends into the cardboard box stacking rack 521, and adsorbs the bottom cardboard box on the cardboard box stacking rack 521; then the cardboard box picking cylinder 533 resets and pulls the bottom cardboard box downward; the cardboard box will deform under the action of its own pre-folding crease, so that the four side walls of the cardboard box close to form a parallelogram; the bottom area of ​​the cardboard box becomes smaller, so that it can fall over the cardboard box limiting block 523 and onto the operating table 510, thereby realizing the cardboard box picking process. Then, the conveying cylinder 531 works to drive the paper box picking cylinder 533 to move the paper box to the position on the operating table 510 corresponding to the bottom forming mechanism 550, thus realizing the paper box transfer process.

[0054] To limit and guide the movement direction of the paper tray suction cup 535, two paper tray guide sleeves 536 are provided on the paper tray mounting block 532. Paper tray guide rods 537 are respectively provided on the suction cup fixing block 534 at corresponding positions to the paper tray guide sleeves 536. The paper tray guide rods 537 pass through the corresponding paper tray guide sleeves 536, and the two are slidably engaged. The cooperation between the paper tray guide rods 537 and the paper tray guide sleeves 536 limits and guides the lifting and lowering movement direction of the paper tray suction cup 535, improving the stability and accuracy of the transmission.

[0055] like Figure 17 As shown, the cardboard box feeding robot 540 includes a robot arm mounting frame 541, which is fixedly connected to the machine base 100. A feeding transverse module 542 is mounted on the robot arm mounting frame 541. A feeding lifting module 543 is mounted on the output end of the feeding transverse module 542. A suction mounting block 544 is mounted on the output end of the feeding lifting module 543. A cardboard box feeding suction cup 545 is mounted on the suction mounting block 544, and the cardboard box feeding suction cup 545 is externally connected to a negative pressure device. In this embodiment, the feeding transverse module 542 and the feeding lifting module 543 can be either a motor screw module or a motor synchronous belt module; their specific structures will not be described in detail here.

[0056] During processing, the cooperation of the feeding transverse module 542 and the feeding lifting module 543 drives the paper box feeding suction cup 545 to move onto the paper box on the operating table 510. External negative pressure causes the paper box feeding suction cup 545 to generate suction and adhere to the upper side wall of the paper box. The feeding lifting module 543 then drives the paper box feeding suction cup 545 to rise slightly. Meanwhile, the lower side wall of the paper box is held by the paper box picking suction cup 535. Therefore, the lifting module 543's movement of the paper box feeding suction cup 545 upwards deforms the paper box, thus shaping the four side walls of the paper box. Then, the bottom forming mechanism 550 shapes the bottom of the paper box. After shaping, the cooperation of the feeding transverse module 542 and the feeding lifting module 543 drives the paper box feeding suction cup 545 to grasp the shaped paper box and place it onto the paper box conveyor belt 600, completing the paper box shaping and feeding process.

[0057] An upper folding and bending assembly 560 is provided on the adsorption mounting block 544. The upper folding and bending assembly 560 is connected to the operating table 510 and is used to bend the upper folding edge of the bottom of the paper box on the operating table 510. Specifically, the upper folding and bending assembly 560 includes an upper folding and bending cylinder 561, which is connected to the adsorption mounting block 544. An upper bending block 562 is hinged to the output end of the upper folding and bending cylinder 561 and is hinged to the adsorption mounting block 544. During the bottom forming process of the paper box, the upper folding and bending cylinder 561 can drive the upper bending block 562 to rotate and swing, so that it abuts against the upper folding edge of the bottom of the paper box on the operating table 510 and bends it downwards to pre-form it.

[0058] like Figure 18 As shown, the bottom forming mechanism 550 includes a left edge pressing cylinder 551, a right edge pressing cylinder 552, a lower edge pressing cylinder 553, and an upper edge pressing cylinder 554, which are respectively mounted on the operating table 510. The left edge pressing cylinder 551 and the right edge pressing cylinder 552 are symmetrically arranged on the left and right sides of the upper edge pressing cylinder 554, and the driving directions of the left edge pressing cylinder 551 and the right edge pressing cylinder 552 form an angle of 45° with the side of the operating table 510. The output end of the left edge pressing cylinder 551 is provided with a first inclined push block 555, the output end of the right edge pressing cylinder 552 is provided with a second inclined push block 556, and the output end of the upper edge pressing cylinder 554 is provided with a straight push block 557. A lower folding block 558 is hinged to the output end of the lower pressing cylinder 553. The lower folding block 558 is hinged to the operating table 510. The lower pressing cylinder 553 can drive the lower folding block 558 to rotate and swing along the operating table 510.

[0059] The bottom forming process of the cardboard box is as follows: Before the bottom of the cardboard box is formed, the lower side wall 201 of the cardboard box 200 on the operating table 510 is held by the cardboard box suction cup 535. When forming the bottom of the cardboard box, the cardboard box feeding suction cup 545 is driven to hold the upper side wall 202 of the cardboard box through the cooperation of the feeding transverse module 542 and the feeding lifting module 543, and the cardboard box feeding suction cup 545 is driven to rise slightly through the feeding lifting module 543, so that the four sides of the cardboard box are formed in place.

[0060] Then, the lower pressing cylinder 553 is controlled to operate, driving the lower folding block 558 to rotate and swing, pushing the lower folding edge 203 of the cardboard box on the operating table 510 to flip upwards, fold into shape, and press firmly. Next, the left pressing cylinder 551 and the right pressing cylinder 552 are controlled to operate, with the first oblique push block 555 and the second oblique push block 556 pressing firmly the left and right folding edges of the bottom of the cardboard box, respectively. Then, the upper folding edge bending cylinder 561 is controlled to operate, with the upper bending block 562 bending the upper folding edge 204 at the bottom of the cardboard box. Finally, the upper pressing cylinder 554 is controlled to operate, with the straight push block 557 engaging the upper folding edge at the bottom of the cardboard box inside the lower folding edge, completing the bottom forming action of the cardboard box.

[0061] After the bottom of the cardboard box is formed, the formed cardboard box is taken off the operating table 510 and placed on the cardboard box conveyor belt 600 through the cooperation of the feeding transverse module 542 and the feeding lifting module 543, thus completing the entire cardboard box feeding and forming process.

[0062] like Figure 19 As shown, the paper box conveyor belt 600 includes a paper box conveyor mounting frame 601, which is connected to the machine base 100. The paper box conveyor mounting frame 601 is equipped with a paper box feeding motor 602 and a paper box feeding belt 603. The output end of the paper box feeding motor 602 is connected to the paper box feeding belt 603. The paper box feeding motor 602 can drive the paper box feeding belt 603 to rotate on the paper box conveyor mounting frame 601. Paper box placement blocks 604 are evenly distributed on the paper box feeding belt 603. The paper box placement blocks 604 are used to limit the paper boxes.

[0063] In actual operation, the cardboard box feeding and forming mechanism 500 places the empty cardboard box onto the cardboard box placement block 604. The cardboard box placement block 604 can limit the cardboard box on the cardboard box conveyor belt 603, thereby preventing the cardboard box from deforming or shifting. Then, the cardboard box conveyor motor 602 drives the cardboard box conveyor belt 603 to move step by step, thereby conveying the formed empty cardboard box to the processing position of the blood collection needle boxing mechanism 700. At the same time, the working fluid of the cardboard box conveyor motor 602 can convey the cardboard box with blood collection needles installed in the blood collection needle boxing mechanism 700 to the lid unloading mechanism 800.

[0064] like Figure 20-22As shown, the lancet boxing mechanism 700 includes a lancet transfer boxing assembly and a box pressing assembly 710, both mounted on the machine base 100. The lancet transfer boxing assembly is connected to the lancet conveying and transferring mechanism 400. The lancet transfer boxing assembly includes a receiving and transferring mechanism 720 and a lancet pushing mechanism 730. The receiving and transferring mechanism 720 transports the lancets to the box position on the box conveyor belt 600, and the lancet pushing mechanism 730 pushes the lancets into the box on the box conveyor belt 600. The box pressing assembly 710 is located on the side of the box conveyor belt 600 away from the lancet transfer boxing assembly. The box pressing assembly 710 presses the folded edges on both sides of the box and can limit the lancets inside the box.

[0065] During operation, the lancet conveying and transfer mechanism 400 transports the lancets to the receiving and transfer mechanism 720, while the cardboard box feeding and forming mechanism 500 transports the formed cardboard boxes to the cardboard box conveyor belt 600. The cardboard box conveyor belt 600 transports the formed cardboard boxes to the processing position of the lancet transfer and box-insertion assembly; then, the receiving and transfer mechanism 720 transports the lancets to the cardboard boxes on the cardboard box conveyor belt 600 for alignment; then, the lancet pushing mechanism 730 pushes the lancets into the cardboard boxes; finally, the cardboard box pressing assembly 710 works to press the folded edges on both sides of the cardboard box, sealing the lancets inside the cardboard box to prevent them from falling out, thus completing the lancet insertion process.

[0066] like Figure 21 As shown, the material receiving and transfer mechanism 720 includes a transfer motor 721, which is fixedly connected to the machine base 100. A transfer mounting block 722 is provided on the output end of the transfer motor 721. A receiving frame 723 is provided at each end of the transfer mounting block 722. The blood collection needle conveying and transfer mechanism 400 can place the blood collection needles to be boxed into the receiving frame 723 according to a preset number. The transfer motor 721 can drive the two receiving frames 723 to interchange positions, thereby aligning them with the carton conveyor belt 600 or the blood collection needle conveying and transfer mechanism 400. The double receiving frame 723 design allows the two receiving frames 723 to work alternately. When one receiving frame 723 receives material, the other receiving frame 723 pushes the material into the box, effectively improving the equipment's working efficiency.

[0067] The blood collection needle pushing mechanism 730 is installed on the transfer mounting block 722 and is arranged in a one-to-one correspondence with the receiving box 723. That is, in this embodiment, a blood collection needle pushing mechanism 730 is respectively arranged on the transfer mounting block 722 at a position corresponding to each receiving box 723.

[0068] Specifically, the blood collection needle pushing mechanism 730 includes a sealing door opening and closing assembly and a pushing assembly. The sealing door opening and closing assembly is connected to the receiving frame 723 and is used to block or open one end of the receiving frame 723; the pushing assembly is connected to the receiving frame 723 and is used to push the blood collection needle out of the receiving frame 723.

[0069] The closing door opening and closing assembly includes an opening and closing cylinder 731, which is fixedly connected to the transfer mounting block 722. A closing door 732 is provided on the output end of the opening and closing cylinder 731. The opening and closing cylinder 731 can drive the closing door 732 to block or disengage from the end face of the receiving frame 723. When the receiving frame 723 is in the receiving position, the opening and closing cylinder 731 drives the closing door 732 to descend, allowing the closing door 732 to block the end of the receiving frame 723, so that the blood collection needle feeding mechanism can smoothly place the blood collection needle into the receiving frame 723. When the receiving frame 723 is in the pushing and boxing position, the opening and closing cylinder 731 drives the closing door 732 to rise, allowing the closing door 732 to disengage from the end of the receiving frame 723, so that the pushing assembly can push the blood collection needle out of the receiving frame 723, completing the boxing process.

[0070] The pushing component includes a pushing cylinder 733, which is connected to the transfer mounting block 722. A pushing block 734 is provided on the output end of the pushing cylinder 733. The pushing cylinder 733 can drive the pushing block 734 to extend into or out of the receiving frame 723. Normally, the pushing block 734 extends out of the receiving frame 723. When the receiving frame 723 is equipped with blood collection needles and has moved to the box-entry position, the opening / closing cylinder 731 is first controlled to drive the closing door 732 upwards, and then the pushing cylinder 733 is controlled to operate. The pushing cylinder 733 pushes the pushing block 734 into the receiving frame 723. As the pushing cylinder 733 continues to operate, the pushing block 734 pushes the blood collection needles out of the receiving frame 723 and into the cardboard box on the cardboard conveyor belt 600, completing the blood collection needle insertion and pushing process.

[0071] like Figure 22 As shown, the paper box edge pressing assembly 710 includes an edge pressing fixing seat 711, an edge pressing forward pushing cylinder 712 on the edge pressing fixing seat 711, two edge fastening mounting blocks 713 on the output end of the edge pressing forward pushing cylinder 712, and edge pressing cylinders 714 on the edge fastening mounting blocks 713 respectively. An edge fastening push block 715 is hinged to the output end of the edge pressing cylinder 714, and the edge fastening push block 715 is hinged to the edge fastening mounting block 713. The edge pressing forward pushing cylinder 712 can drive the edge fastening push block 715 to abut against the paper box folded edge on the paper box conveyor belt 604, and push the folded edge of the paper box to be flush with the side wall of the paper box. The edge pressing cylinder 714 can drive the edge fastening push block 715 to rotate and swing, thereby pressing the folded edge of the paper box on the paper box conveyor belt 604, so that it is in contact with the end face of the blood collection needle inside the paper box.

[0072] It should be noted that, as Figure 14 As shown, after the cardboard box is formed, the folded edges 205 on both sides of the cardboard box are in an upward-curving state to facilitate the insertion of the lancet into the cardboard box. After the lancet is inserted into the cardboard box, the folded edges 205 of the cardboard box need to be bent to fasten to the end of the lancet inside the cardboard box, so that the cover of the cardboard box can be closed later. Therefore, in actual operation, after the lancet is inserted into the box, the pressing cylinder 712 drives the fastening mounting block 713 to drive the fastening push block 715 to abut against the folded edge of the cardboard box on the cardboard box conveyor belt 604. The fastening push block 715 pushes the folded edge of the cardboard box inward until it is flush with the side wall of the cardboard box. Then, the pressing cylinder 714 drives the fastening push block 715 to press the folded edge of the cardboard box inward until it is in contact with the end face of the lancet inside the cardboard box, thereby completing the fastening action of the cardboard box.

[0073] The edge-pressing fixing seat 711 is also equipped with a blood collection needle limiting cylinder 716. The output end of the blood collection needle limiting cylinder 716 is equipped with a blood collection needle limiting plate 717. The blood collection needle limiting cylinder 716 can drive the blood collection needle limiting plate 717 to seal or open the opening end of the paper box on the paper box conveyor belt 600. After the blood collection needle is inserted into the paper box, since the top cover 206 of the paper box is not yet closed, in order to prevent the blood collection needle from falling out of the paper box, the blood collection needle limiting cylinder 716 needs to work to drive the blood collection needle limiting plate 717 to descend, so as to seal the opening end of the paper box.

[0074] like Figure 22 As shown, the machine tool 100 is equipped with a synchronous conveying module 740. The pressing edge fixing seat 711 is connected to the output end of the synchronous conveying module 740. The synchronous conveying module 740 can drive the pressing edge fixing seat 711 to move along the movement direction of the paper box conveyor belt 600. At the same time, it is necessary to ensure that the moving speed of the pressing edge fixing seat 711 driven by the synchronous conveying module 740 is the same as the moving speed of the paper box placement block 605, so as to ensure that the blood collection needle limiting plate 717 can always block the opening end of the paper box on the paper box conveyor belt 600 and prevent the blood collection needle from falling out of the paper box.

[0075] The synchronous conveying module 740 can adopt existing linear modules that can achieve stepping movement, such as motor screw modules and motor synchronous belt modules.

[0076] During processing, the lancet conveying and transfer mechanism 400 transports the lancets to the receiving frame 723 of the lancet transfer box assembly, while the cardboard box feeding and forming mechanism 500 transports the formed cardboard boxes to the cardboard box placement block 605 of the cardboard box conveyor belt 600. Then, the cardboard box feeding motor 603 and the transfer motor 721 are controlled to operate. The cardboard box feeding motor 603 drives the cardboard box feeding belt 604 to rotate, transporting the cardboard boxes to the position aligned with the receiving frame 723. The transfer motor 721 drives the transfer mounting block 722 to rotate, causing the receiving frame 723 filled with lancets to rotate to the position aligned with the cardboard box, while the empty receiving frame 723 rotates to the receiving position to continue receiving lancets.

[0077] Then, the opening and closing cylinder 731 drives the closing door 732 to open the end of the receiving frame 723; then, the pushing cylinder 733 drives the pushing block 734 to push the blood collection needle into the paper box.

[0078] Subsequently, the blood collection needle limiting cylinder 716 drives the blood collection needle limiting plate 717 to seal the opening end of the cardboard box, preventing the blood collection needle from coming out. Then, the edge pressing cylinder 712 drives the edge-fastening push block 715 to abut against the folded edge of the cardboard box, pushing the folded edge of the cardboard box flush with the side wall of the cardboard box. Then, the edge pressing cylinder 714 drives the edge-fastening push block 715 to press the folded edge of the cardboard box tightly, so that it is in contact with the end face of the blood collection needle, completing the folding action of the cardboard box.

[0079] During the folding process of the cardboard box, the synchronous conveying module 740 drives the edge pressing fixing seat 711 and the cardboard box placement block 605 to move synchronously, ensuring that the edge pressing operation can be completed during the cardboard box conveying process, thus improving production efficiency. After the edge pressing is completed, the cardboard box containing the blood collection needles is also conveyed by the cardboard box conveyor belt 600 to the processing position of the lid unloading mechanism 800.

[0080] like Figure 23-27 As shown, the lid box unloading mechanism 800 includes a lid box assembly, an unloading robot 810, and an unloading conveyor belt 820, all of which are respectively mounted on the machine base 100.

[0081] The paper box conveyor belt 600 is connected to the blood collection needle boxing mechanism 700, the lid assembly, and the unloading robot 810. It can sequentially transport the paper boxes with blood collection needles loaded in the blood collection needle boxing mechanism 700 to the lid assembly and the unloading robot 810. The unloading robot 810 is used to pick up the paper boxes with the lid on from the paper box conveyor belt 600 and place them on the discharge conveyor belt 820. The discharge conveyor belt 820 is used to send the paper boxes with the lid on out of the machine 100.

[0082] The lid assembly includes a lid guide mechanism 830, a folding edge mechanism 840, and a pressing mechanism 850. The lid guide mechanism 830 is used to bend the lid of the paper box on the paper box conveyor belt 600, the folding edge mechanism 840 is used to bend the snap edge of the paper box lid, and the pressing mechanism 850 is used to push the snap edge of the paper box lid into the paper box.

[0083] like Figure 14 As shown, in this embodiment, the cardboard box 200 is provided with a top cover 206. A crease is reserved between the box body and the top cover 206. One end of the top cover 206 is provided with a snap-on edge 207, and a crease is reserved between the snap-on edge 207 and the top cover 206. After the cardboard box is formed by the cardboard box feeding and forming mechanism 500, the top cover 206 of the cardboard box is flush with the lower side wall 201. The function of the top cover guiding mechanism 830 is to bend the top cover 206 along the crease. The function of the folding edge mechanism 840 is to bend the snap-on edge 207 along the crease of the top cover 206. The function of the pressing mechanism 850 is to close the top cover 206 onto the box body and insert the snap-on edge 207 into the box body, thereby completing the box closing action.

[0084] like Figure 24 As shown, the unloading robot 810 includes an unloading fixed frame 811, which is connected to the machine base 100. The unloading fixed frame 811 is equipped with an unloading transverse module 812, an unloading lifting module 813 at its output end, an unloading gripper cylinder 814 at its output end, and two unloading clamping blocks 815 at their output end. Through the cooperation of the unloading transverse module 812 and the unloading lifting module 813, the unloading gripper cylinder 814 can be driven to move back and forth between the discharge conveyor belt 820 and the carton conveyor belt 600. Furthermore, the unloading gripper cylinder 814 drives the two unloading clamping blocks 815 to close or separate, thereby achieving the gripping and release of the carton. In this embodiment, both the unloading transverse module 812 and the unloading lifting module 813 can adopt any existing linear drive device, such as a cylinder module, an electric cylinder module, or a motor lead screw module; the present invention does not limit their specific structure.

[0085] like Figure 25As shown, the top cover guiding mechanism 830 includes a guide frame 831, which is fixedly connected to the machine base 100. A top cover guiding plate 832 is provided on the guide frame 831 and is located on one side of the carton conveyor belt 600. After the blood collection needle loading mechanism 700 loads the blood collection needles, the top cover of the carton will be laid flat on the top cover guiding plate 832. As the carton conveyor belt 600 operates and drives the carton to move, the top cover of the carton will slide on the top cover guiding plate 832. An inclined guiding part 833 is provided on the top cover guiding plate 832 at a position corresponding to the capping mechanism 850. The inclined guiding part 833 slopes upwards from the top cover guiding plate 832 towards the carton conveyor belt 600. As the carton conveyor belt 600 transports the carton containing the blood collection needles to the processing position of the capping mechanism 850, the top cover of the carton slides on the inclined guide 833. Under the pressure of the inclined guide 833, the top cover of the carton bends upward, so that the buckle at one end of the top cover can be aligned with the folding edge mechanism 840, so that the folding edge mechanism 840 can bend the buckle of the carton in the future.

[0086] like Figure 26 As shown, the capping mechanism 850 includes a capping mounting frame 851, a capping cylinder 852 is provided on the capping mounting frame 851, and a capping pusher 853 is provided on the output end of the capping cylinder 852. The capping cylinder 852 can drive the capping pusher 853 to abut against the top cover of the paper box on the paper box conveyor belt 600.

[0087] like Figure 26-27 As shown, the folding edge mechanism 840 includes a folding edge mounting frame 841, which is connected to the machine base 100. A blocking cylinder 842 is mounted on the folding edge mounting frame 841, and a blocking rod 843 is mounted on the output end of the blocking cylinder 842. The blocking rod 843 is used to limit the position of the carton cover. The blocking cylinder 842 can drive the blocking rod 843 to extend into the connection position between the carton cover and the snap-edge on the carton conveyor belt 600, thereby preventing the carton cover from bending synchronously with the snap-edge. A folding edge cylinder 844 is mounted on the cap mounting frame 851, and a snap-edge bending block 845 is mounted on the output end of the folding edge cylinder 844. The folding edge cylinder 844 can drive the snap-edge bending block 845 to engage or disengage from the snap-edge of the carton cover.

[0088] During processing, when the cardboard box conveyor belt 600 transports the cardboard box containing the blood collection needles to the processing position of the capping mechanism 850, the top cover of the cardboard box will first bend upward along the oblique guide part 833 of the top cover guide plate 832, so that the buckle edge at one end of the top cover of the cardboard box can be aligned with the folding edge mechanism 840. Next, the blocking cylinder 842 is activated, driving the blocking rod 843 to extend into the connection position between the cardboard box lid and the snap-on edge. Then, the folding cylinder 844 is activated, driving the snap-on bending block 845 to engage with the snap-on edge of the cardboard box. As the folding cylinder 844 continues to move, the snap-on bending block 845 pushes the snap-on edge of the cardboard box inward until it is bent into place. Then, the blocking cylinder 842 is reset, causing the blocking rod 843 to extend out of the cardboard box lid. Then, the capping cylinder 852 is activated, driving the capping push block 853 to engage with the cardboard box lid. As the capping cylinder 852 continues to work, the capping push block 853 pushes the snap-on edge of the cardboard box into the cardboard box and covers the blood collection needle inside the cardboard box with the cardboard box lid, thus completing the cardboard box closing action. Then, the cardboard box with the top cover is transported to the gripping position of the unloading robot 810 via the cardboard box conveyor belt 600. Through the cooperation of the unloading lateral movement module 812 and the unloading lifting module 813, the unloading gripper cylinder 814 can be driven to grab the cardboard box with the top cover from the cardboard box conveyor belt 600. Then, through the cooperation of the unloading lateral movement module 812 and the unloading lifting module 813, the unloading gripper cylinder 814 can be driven to move to the position of the discharge conveyor belt 820. By controlling the unloading gripper cylinder 814 to release the cardboard box, the cardboard box with the top cover is placed on the discharge conveyor belt 820. Then, the cardboard box is sent out of the machine 100 via the discharge conveyor belt 820, completing the automatic boxing and unloading of blood collection needles.

The detection component improves feeding accuracy by taking pictures to identify the position and status of the blood collection needles.

[0091] 3. The material handling and variable pitch mechanism in the blood needle conveying and transfer mechanism, through the cooperation of the variable pitch drive component and the inclined guide groove, realizes the adjustment of the spacing of multiple gripping suction cups, thereby adapting to the arrangement requirements of different specifications of cardboard boxes and blood collection needles, and enhancing the versatility of the equipment.

[0092] 4. The paper box feeding and forming mechanism, through the cooperation of the paper box stacking mechanism, the paper box picking mechanism and the bottom forming mechanism, realizes automatic paper box picking, pre-forming and bottom forming, ensuring stable paper box supply and consistent forming quality.

[0093] 5. The blood collection needle boxing mechanism accurately pushes the blood collection needles into the cardboard box through the material receiving and transfer mechanism and the blood collection needle pushing mechanism, and combines the cardboard box edge pressing component to press the cardboard box folded edge to prevent the blood collection needles from shifting during transportation and ensure that the boxing is secure.

[0094] 6. The lid feeding mechanism completes the bending, edge bending and pressing operations of the carton lid step by step through the lid guiding mechanism, the folding edge mechanism and the pressing mechanism, ensuring that the carton is well sealed. The feeding robot and the discharge conveyor belt realize automatic feeding, improving the overall efficiency.
