[0038] The invention will now be further described with reference to the accompanying drawings.

[0039] Example 1: This example provides a fully automatic cutting device for medical needles, such as... Figures 1-10 As shown, the device includes a delivery mechanism 1 and a cannulation mechanism 3. The delivery mechanism 1 is provided with a plurality of first placement slots 2, which are used to store medical needles 5 to be cannulated 11. The cannulation mechanism 3 is provided with a plurality of second placement slots 4, which are used to place cannulas 11. The second placement slots 4 correspond to the first placement slots 2. The cannulation mechanism 3 is used to put the cannulas 11 in each of the second placement slots 4 onto the medical needles 5 to be cannulated 11 in each of the first placement slots 2.

[0040] For example, in practice, the fully automatic cutting device for the medical needle 5 also includes a support base 10.

[0041] The conveying mechanism 1 is connected to the support base 10 by means of screwing, welding or other methods. The conveying mechanism 1 has a first placement slot 2 for storing medical needles 5 to be sheathed 11. The number of first placement slots 2 is set to a certain extent so that multiple medical needles 5 to be sheathed 11 can be stored in an orderly manner in each of the first placement slots 2.

[0042] The sleeve mechanism 3 is connected to the support base 10 by means of screw fixing, welding fixing, etc. The sleeve mechanism 3 is arranged in parallel with the conveying mechanism 1, and the sleeve mechanism 3 is provided with a second placement slot 4 for storing the sleeve 11. The number of second placement slots 4 corresponds to the number of first placement slots 2. During the operation of the conveying mechanism 1, the first placement slots 2 can be made to correspond one-to-one with the second placement slots 4 on the sleeve mechanism 3.

[0043] During use, the needle handles 52 of multiple medical needles 5 to be cannulated 11 are first placed in the first placement slot 2 on the conveying mechanism 1, and multiple cannulas 11 are arranged in the second placement slot 4 on the cannulation mechanism 3. Next, the conveying mechanism 1 is driven to operate, so that the needle bodies 51 of the multiple medical needles 5 correspond one-to-one with the multiple cannulas 11 in the second placement slot 4. Then, the cannulation mechanism 3 is driven to simultaneously insert the multiple cannulas 11 in the second placement slot 4 onto the needle bodies 51 of the medical needles 5 in the first placement slot 2, and the cannulas 11 are secured to the needle handles 52. On the one hand, this aims to achieve independent cannulation 11 for each medical needle 5, thereby effectively reducing cross-contamination and meeting the packaging requirements for individual protection or aseptic isolation of a single medical needle 5. On the other hand, it aims to achieve continuous and efficient simultaneous cannulation 11 of multiple medical needles 5, thereby improving cannulation efficiency.

[0044] Example 2: Based on Example 1 above, in this example, as follows... Figures 4-5As shown, the cannula mechanism 3 includes a first load-bearing plate 31, a first driving member 32, and a cannula placement plate 33; the first load-bearing plate 31 is arranged in parallel with the conveying mechanism 1; the cannula placement plate 33 is slidably disposed on the first load-bearing plate 31, and the second placement groove 4 is disposed on the cannula placement plate 33; the first driving member 32 is disposed on the first load-bearing plate 31, and the first driving member 32 is connected to the cannula placement plate 33; wherein, the first driving member 32 is used to drive the cannula placement plate 33 to move closer to the conveying mechanism 1, so as to place the cannula 11 in the second placement groove 4 on the cannula placement plate 33 onto the medical needle 5 in the first placement groove 2 on the conveying mechanism 1.

[0045] For example, in the implementation process, the above-mentioned sleeve mechanism 3 includes a first load-bearing plate 31, a first driving member 32, and a sleeve placement plate 33.

[0046] The first load-bearing plate 31 is connected to the support base 10 by welding, screwing or other means, and the first load-bearing plate 31 is installed in parallel with the conveying mechanism 1.

[0047] The sleeve placement plate 33 is slidably mounted on the first load-bearing plate 31 via a guide rail and a slider, so that the sleeve 11 can move towards or away from the conveying mechanism 1. Several second placement slots 4 are arranged on the sleeve placement plate 33.

[0048] The first driving component 32 can be a cylinder, an electric actuator, or a servo linear module. The first driving component 32 is connected to the first load-bearing plate 31 by means of screw fixing or snap-fit, and the output shaft of the first driving component 32 is connected to the sleeve placement plate 33 so that the first driving component 32 can drive the sleeve placement plate 33 to move closer to or further away from the conveying mechanism 1.

[0049] During operation, the needle handles 52 of multiple medical needles 5 to be fitted with cannulas 11 are first placed in the first placement slot 2 on the delivery mechanism 1, and multiple cannulas 11 are arranged in the second placement slot 4 on the cannula placement plate 33. Next, the delivery mechanism 1 is driven to operate so that the needle bodies 51 of the multiple medical needles 5 correspond one-to-one with the multiple cannulas 11 in the second placement slot 4. Then, the first drive unit 32 is operated to drive the cannula placement plate 33 to move along the first support plate 31 towards the delivery mechanism 1, thereby fitting the cannulas 11 in the second placement slot 4 onto the needle bodies 51 of the medical needles 5 in the first placement slot 2, and securing the cannulas 11 to the needle handles 52. After the cannulas 11 are fitted, the first drive unit 32 is operated to drive the cannula placement plate 33 away from the delivery mechanism 1 along the first support plate 31, moving it back to the initial position, ready for the next round of operation. The aim is to achieve the goal of moving the cannula placement plate 33 as a whole, so that all cannulas 11 are inserted into the needle body 51 of the corresponding medical needle 5 synchronously, in the same direction and at equal intervals, thereby reducing the risk of misalignment caused by individual cannulas 11, and thus improving the consistency of cannulas 11 and product quality.

[0050] Example 3: Based on Example 2 above, in this example, as follows... Figure 4 As shown, the sleeve mechanism 3 further includes a sleeve 11 feeding assembly 34; the sleeve 11 feeding assembly 34 includes a second load-bearing plate 341, a second driving member 342, and a storage box 343; the second load-bearing plate 341 is slidably disposed on the first load-bearing plate 31, and the second load-bearing plate 341 is connected to the first driving member 32; the storage box 343 is disposed on the second load-bearing plate 341; the sleeve placement plate 33 is slidably disposed on the second load-bearing plate 341, and the sleeve placement plate 33 is located below the storage box 343; the second driving member 342 is disposed on the second load-bearing plate 341, and the second driving member 342 is slidably connected to the sleeve placement plate 33; wherein, the second driving member 342 is used to drive the sleeve placement plate 33 to slide along the second load-bearing plate 341, so as to lay the sleeve 11 in the sleeve 11 placement box in the second placement groove 4 on the sleeve placement plate 33.

[0051] For example, in the implementation process, the above-mentioned sleeve mechanism 3 also includes a sleeve 11 feeding assembly 34, which includes a second load-bearing plate 341, a second driving component 342 and a storage box 343.

[0052] The second load-bearing plate 341 is slidably mounted on the first load-bearing plate 31 by means of a guide rail and a slider, and the second load-bearing plate 341 is connected to the output shaft of the first drive member 32, so that the second load-bearing plate 341 can move along the first load-bearing plate 31 towards or away from the conveying mechanism 1 under the drive of the first drive member 32.

[0053] The storage box 343 is connected to the second load-bearing plate 341 by means of welding, screwing, or integral molding, and the storage box 343 is used to store the sleeve 11. The bottom of the storage box 343 is provided with a discharge port, and the bottom plate of the storage box 343 gradually slopes downward along the direction close to the discharge port so that the sleeve 11 inside the storage box 343 can slide out from the discharge port.

[0054] The sleeve placement plate 33 is located at the lower end of the storage box 343, and the sleeve placement plate 33 is slidably installed on the second load-bearing plate 341 by means of guide rail and slider cooperation, so that the sleeve placement plate 33 can slide along the second load-bearing plate 341 to the bottom of the storage box 343, and receive and position the sleeve 11 output from the outlet of the storage box 343 through the second placement groove 4.

[0055] The second drive unit 342 adopts a structure such as a cylinder, electric actuator, or servo linear module. The second drive unit 342 is installed on the second load-bearing plate 341 by means of screw fixing or snap-fit, and the output shaft of the second drive unit 342 is connected to the sleeve placement plate 33, so that the second drive unit 342 can drive the sleeve placement plate 33 to move along the second load-bearing plate 341 towards or away from the storage box 343.

[0056] During use, the sleeves 11 are stored in batches in the storage box 343.

[0057] When feeding the sleeve 11, the second drive unit 342 first drives the sleeve placement plate 33 to move along the second support plate 341 towards the storage box 343. When the second placement slot 4 on the sleeve placement plate 33 moves to below the discharge port of the storage box 343, the sleeve 11 in the storage box 343 slides from the discharge port into the second placement slot 4. Next, when all the second placement slots 4 on the sleeve placement plate 33 are filled with sleeves 11, the second drive unit 342 drives the sleeve placement plate 33 to move along the second support plate 341 away from the storage box 343 back to the initial position. On the one hand, this aims to reduce the labor intensity of manual feeding, achieve continuous production, and improve the degree of automation. On the other hand, it aims to reduce the risk of production line stoppage due to manual feeding, thereby improving feeding efficiency and stability. On the other hand, the movement of the sleeve placement plate 33 is precisely controlled by the second drive component 342 in order to ensure that each sleeve 11 can fall accurately into the corresponding second placement slot 4, thereby reducing the risk of missing, misaligned or stacked sleeves.

[0058] When the cannula placement plate 33 moves to the initial position and the needle body 51 of the medical needle 5 corresponds one-to-one with the cannula 11 in the second placement slot 4, the first driving member 32 is activated to drive the second load-bearing plate 341 to move along the first load-bearing plate 31 towards the direction of the conveying mechanism 1, thereby driving the cannula placement plate 33 to move along the first load-bearing plate 31 towards the direction of the conveying mechanism 1.

[0059] Example 4: Based on Example 3 above, in this example, as... Figure 4 As shown, the sleeve 11 feeding assembly 34 further includes a guide roller 344; the guide roller 344 is disposed at the discharge port of the storage box 343, and the guide roller 344 is located above the sleeve placement plate 33; wherein, the distance between the guide roller 344 and the sleeve placement plate 33 is less than the outer diameter of the sleeve 11; the distance between the guide roller 344 and the bottom of the second placement groove 4 is greater than or equal to the outer diameter of the sleeve 11, and the distance between the guide roller 344 and the bottom of the second placement groove 4 is less than twice the outer diameter of the sleeve 11.

[0060] For example, in the implementation process, the above-mentioned sleeve 11 feeding assembly 34 also includes a guide roller 344, which is rotatably connected to the discharge port of the storage box 343 through shaft hole fitting, bearing fitting, or other means. The gap between the guide roller 344 and the sleeve placement plate 33 is less than the outer diameter of the sleeve 11; the distance between the guide roller 344 and the bottom of the second placement groove 4 is greater than or equal to the outer diameter of the sleeve 11, and the distance between the guide roller 344 and the bottom of the second placement groove 4 is less than twice the outer diameter of the sleeve 11.

[0061] During use, when feeding the sleeve 11, the sleeve 11 slides along the bottom plate of the storage box 343 to the discharge port and falls onto the upper surface of the sleeve placement plate 33. Then, the second drive unit 342 is operated to drive the sleeve placement plate 33 to move along the second load-bearing plate 341 towards the storage box 343. At this time, because the gap between the guide roller 344 and the sleeve placement plate 33 is less than the outer diameter of the sleeve 11, the sleeve 11 is blocked by the guide roller 344 on the upper surface of the sleeve placement plate 33. When the second placement groove 4 on the sleeve placement plate 33 moves below the discharge port of the storage box 343, because the distance between the guide roller 344 and the bottom of the second placement groove 4 is greater than or equal to the outer diameter of the sleeve 11, and the distance between the guide roller 344 and the bottom of the second placement groove 4 is less than twice the outer diameter of the sleeve 11, one second placement groove 4 can support one sleeve 11. As the sleeve placement plate 33 moves along the second support plate 341 toward the storage bin 343, each of the second placement slots 4 on the sleeve placement plate 33 carries a sleeve 11. At this time, the second drive member 342 is operated to drive the sleeve placement plate 33 to move along the second support plate 341 away from the storage bin 343. When the sleeve placement plate 33 moves along the second support plate 341 away from the storage bin 343, because the second placement slots 4 carry sleeves 11, and the gap between the guide roller 344 and the sleeve placement plate 33 is less than the outer diameter of the sleeve 11, and the distance between the guide roller 344 and the bottom of the second placement slot 4 is less than twice the outer diameter of the sleeve 11, the sleeves 11 in the storage bin 343 will no longer enter the second placement slots 4. On the one hand, the height-limiting gap between the guide roller 344 and the sleeve placement plate 33 forms a "mechanical selection" mechanism. The aim is to ensure that each second placement slot 4 carries only one sleeve 11, thereby reducing the risk of fabric failure due to stacking or misalignment of sleeves 11 and improving the reliability of automatic feeding. On the other hand, when the sleeve placement plate 33 moves away from the storage box 343 along the second load-bearing plate 341, the distance between the guide roller 344 and the bottom of the second placement slot 4 is greater than or equal to the outer diameter of the sleeve 11, resulting in a gap between the upper end of the sleeve 11 and the guide roller 344 within the second placement slot 4. This aims to reduce the risk of scratching or collision between the guide roller 344 and the sleeve 11.

[0062] Example 5: Based on Example 3 above, in this example, as follows... Figure 4As shown, the sleeve mechanism 3 further includes a first pressing component 35; the first pressing component 35 includes a third driving member 351, a fourth driving member 352, a push plate 353, and a first pressure plate 354; the first pressure plate 354 is disposed on the sleeve placement plate 33; the third driving member 351 is disposed on the second load-bearing plate 341, and the third driving member 351 is connected to the first pressure plate 354; wherein, the third driving member 351 is used to drive the first pressure plate 354 to move towards the sleeve placement plate 33, so that the sleeve mechanism 354 is positioned closer to the sleeve placement plate 33, thereby causing the sleeve to be placed closer to the first pressure plate 354. The first pressure plate 354 is attached to the sleeve 11 in the second placement groove 4 on the sleeve placement plate 33; the push plate 353 is disposed on the side of the sleeve placement plate 33 away from the conveying mechanism 1; the fourth driving member 352 is disposed on the second load-bearing plate 341 and is connected to the push plate 353; wherein, the fourth driving member 352 is used to drive the push plate 353 to move closer to the sleeve placement plate 33, so as to move the sleeve 11 in the second placement groove 4 closer to the conveying mechanism 1.

[0063] For example, in the implementation process, the above-mentioned sleeve mechanism 3 also includes a first pressing component 35, which includes a third driving member 351, a fourth driving member 352, a push plate 353 and a first pressure plate 354.

[0064] Both the third drive unit 351 and the fourth drive unit 352 can be constructed using cylinders, electric actuators, or servo linear modules. Furthermore, both the third drive unit 351 and the fourth drive unit 352 are connected to the second load-bearing plate 341 via screws, snap-fit ​​connectors, or other methods.

[0065] The first pressure plate 354 is positioned above the sleeve placement plate 33, and the first pressure plate 354 is connected to the output shaft of the third drive component 351 by means of welding, screwing, or other methods.

[0066] The push plate 353 is located on the side of the sleeve placement plate 33 away from the conveying mechanism 1, and the push plate 353 is connected to the output shaft of the fourth drive component 352 by means of welding, screwing or other methods.

[0067] During use, all the second placement slots 4 on the sleeve placement plate 33 receive sleeves 11, and the second driving member 342 drives the sleeve placement plate 33 to move along the second load-bearing plate 341 away from the storage box 343 to the initial position. First, the third driving member 351 is operated to drive the first pressure plate 354 to move closer to the sleeve placement plate 33 until the first pressure plate 354 is attached to the top of the sleeve 11 on the sleeve placement plate 33. Next, the fourth driving member 352 is operated to drive the push plate 353 to move closer to the sleeve placement plate 33 and push the sleeves 11 in the second placement slots 4 closer to the conveying mechanism 1 until the push plate 353 is attached to the sleeve placement plate 33. Next, the first drive unit 32 is operated to drive the second support plate 341 to move along the first support plate 31 towards the direction of the conveying mechanism 1, thereby driving the cannula placement plate 33 to move along the first support plate 31 towards the direction of the conveying mechanism 1, so as to put the cannula 11 onto the needle body 51 of the medical needle 5 and to snap the cannula 11 onto the needle handle 52. On the one hand, before putting the cannula 11 onto the needle body 51 of the medical needle 5, the fourth drive unit 352 drives the push plate 353 to push the cannula 11 in the second placement groove 4 towards the direction of the conveying mechanism 1. This is intended to increase the exposed length of the cannula 11 on the side of the cannula 11 closest to the conveying mechanism 1, thereby facilitating the putting of the cannula 11 onto the needle body 51 of the medical needle 5. On the other hand, after the cannula 11 is put onto the needle body 51 of the medical needle 5, during the process of further snapping the cannula 11 onto the needle handle 52, the push plate 353 abuts against the end of the cannula 11 away from the conveying mechanism 1. The purpose is to limit the end of the cannula 11 away from the delivery mechanism 1, thereby facilitating the engagement of the cannula 11 onto the needle handle 52 of the medical needle 5. Furthermore, during the process of engaging the cannula 11 onto the needle body 51 of the medical needle 5 and then onto the needle handle 52, the first pressure plate 354 presses against the top of the cannula 11, effectively reducing the risk of the cannula 11 bending. This aims to reduce the risk of the cannula 11 popping out of the second placement slot 4. Simultaneously, it aims to ensure the coaxiality of the cannula 11 and the needle body 51, thereby significantly reducing the risks of "misalignment" and "needle jamming," thus improving product quality.

[0068] In practical use, when the diameter of the needle body 51 of the medical needle 5 is small, it is prone to bending under its own weight, thereby increasing the difficulty of using the cannula 11. Therefore, in order to reduce the risk of increased difficulty in using the cannula 11 due to the bending of the needle body 51, Example 6: Based on Example 2 above, in this example, as... Figure 6As shown, the sleeve mechanism 3 further includes a guide assembly 36; the guide assembly 36 includes a guide plate 361, a first connecting plate 362, a fifth driving member 363, and a sixth driving member 364; the first connecting plate 362 is slidably disposed on the first load-bearing plate 31; the fifth driving member 363 is disposed on the first load-bearing plate 31, and the fifth driving member 363 is connected to the first connecting plate 362; wherein, the fifth driving member 363 is used to drive the first connecting plate 362 to move along the sleeve placement plate 33 toward the conveying mechanism 1; the guide plate 361 is disposed on the sleeve Between the placement plate 33 and the conveying mechanism 1; the guide plate 361 is slidably disposed on the first connecting plate 362; there are two guide plates 361, and the two guide plates 361 are arranged sequentially from the upper end of the first connecting plate 362 to the lower end of the first connecting plate 362; the sixth driving member 364 is disposed on the first connecting plate 362, and the sixth driving member 364 is connected to the guide plate 361; wherein, the sixth driving member 364 is used to drive the two guide plates 361 to move closer to each other, so as to clamp the needle body 51 of the medical needle 5 in the first placement groove 2.

[0069] For example, in the implementation process, the above-mentioned sleeve mechanism 3 also includes a guide assembly 36, which includes a guide plate 361, a first connecting plate 362, a fifth driving member 363 and a sixth driving member 364.

[0070] The first connecting plate 362 is slidably mounted on the first load-bearing plate 31 by means of a guide rail and a slider, so that the first connecting plate 362 can move toward the conveying mechanism 1.

[0071] The fifth drive component 363 can be a cylinder, an electric actuator, or a servo linear module. The fifth drive component 363 is mounted on the first load-bearing plate 31 by welding, screwing, or other methods, and its output shaft is connected to the first connecting plate 362 by welding, screwing, or other methods. This allows the fifth drive component 363 to drive the first connecting plate 362 to move closer to the conveying mechanism 1.

[0072] A guide plate 361 is disposed between the cannula placement plate 33 and the delivery mechanism 1, and one end of the guide plate 361 is slidably mounted on the connecting plate through a guide rail and a slider, so that the guide plate 361 can move along the upper end of the connecting plate to the lower end of the connecting plate. There are two guide plates 361, which are disposed opposite to each other at the upper and lower ends of the connecting plate, and the two guide plates 361 are located on the upper and lower sides of the medical needle 5, respectively.

[0073] The sixth drive unit 364 can be a cylinder, an electric actuator, or a servo linear module. The sixth drive unit 364 is installed on the first load-bearing plate 31 by welding, screwing, or other methods, and the output shaft of the sixth drive unit 364 is connected to both guide plates 361 to drive the two guide plates 361 to move closer or further apart.

[0074] During use, when the delivery mechanism 1 is operated to align the needle bodies 51 of multiple medical needles 5 with the multiple sheaths 11 in the second placement slot 4, the fifth drive unit 363 is first operated to move the first connecting plate 362 closer to the delivery mechanism 1 until the two guide plates 361 are positioned on the upper and lower sides of the needle body 51 of the medical needles 5. Next, the sixth drive unit 364 is operated to move the two guide plates 361 closer together until they are abutting the upper and lower sides of the needle body 51 of the medical needles 5. At this point, the needle body 51 corresponds to the sheath 11 in the second placement slot 4. Then, the first drive unit 32 is operated to move the sheath placement plate 33 along the first load-bearing plate 31 closer to the delivery mechanism 1, thereby fitting the sheath 11 in the second placement slot 4 onto the needle body 51 of the medical needles 5 in the first placement slot 2, and securing the sheath 11 to the needle handle 52. The needle body 51 is held in place by two guide plates 361 on the upper and lower sides to reduce the bending, offset and shaking of the needle body 51 caused by vibration, gravity or assembly gap, thereby improving the coaxiality of the sleeve 11 and the needle body 51, reducing the risk of "misalignment" and "needle jamming", reducing the difficulty of sleeve 11 and improving product quality.

[0075] After the sleeve 11 is completed, firstly, operate the first drive member 32 to move the sleeve placement plate 33 along the first load-bearing plate 31 away from the conveying mechanism 1 to its initial position. Next, operate the sixth drive member 364 to move the two guide plates 361 away from each other. Then, operate the fifth drive member 363 to move the first connecting plate 362 away from the conveying mechanism 1.

[0076] In a preferred embodiment, V-grooves are provided on the sides of the two guide plates 361 that are close to each other, and the V-grooves on the two guide plates 361 correspond to the positions of the second placement groove 4. That is, when the two guide plates 361 are close to each other and respectively attached to the upper and lower sides of the needle body 51, the needle body 51 corresponds to the sleeve 11 in the second placement groove 4. The groove walls of the V-grooves limit the needle body 51. This is intended to further reduce the bending, displacement, and shaking of the needle body 51 caused by vibration, gravity, or assembly gaps.

[0077] Example 7: Based on Example 1 above, in this example, as follows... Figure 1 Combination Figure 7As shown, the cutting nozzle device further includes a second pressing component 6; the second pressing component 6 is disposed above the conveying mechanism 1, and the second pressing component 6 and the sleeve mechanism 3 are arranged sequentially along the conveying direction of the conveying mechanism 1; the second pressing component 6 includes a seventh driving member 61 and a second pressure plate 62; the second pressure plate 62 is disposed above the conveying mechanism 1; the seventh driving member 61 is disposed above the conveying mechanism 1, and the seventh driving member 61 is connected to the second pressure plate 62; wherein, the seventh driving member 61 is used to drive the second pressure plate 62 to move towards the conveying mechanism 1, so as to press the needle handle 52 of the medical needle 5 into the first placement groove 2 on the conveying mechanism 1.

[0078] For example, in implementation, the above-mentioned water-cutting device further includes a second pressing component 6, which is disposed above the conveying mechanism 1, and the pressing component and the sleeve mechanism 3 are arranged sequentially along the conveying direction of the conveying mechanism 1. That is, the second pressing component 6 is located on the side of the sleeve mechanism 3 near the feed end of the conveying mechanism 1.

[0079] The second pressing assembly 6 includes a seventh driving component 61 and a second pressure plate 62. The seventh driving component 61 can be a cylinder, an electric actuator, or a servo linear module. The seventh driving component 61 is connected to the support base 10 via a support frame and is located above the conveying mechanism 1. The second pressure plate 62 is connected to the output shaft of the seventh driving component 61 by welding, screwing, or other methods, and is located above the conveying mechanism 1, corresponding to the first placement slot 2 on the conveying mechanism 1.

[0080] During use, when the conveying mechanism 1 transports the first placement slot 2 to below the second pressure plate 62, the needle handles 52 of a row of medical needles 5 are first placed on each of the first placement slots 2. Then, the seventh drive unit 61 is operated to move the second pressure plate 62 closer to the conveying mechanism 1, pressing the needle handles 52 of the medical needles 5 into the first placement slots 2. This aims to reduce the risk of the medical needles 5 slipping out of the first placement slots 2 due to vibration when the conveying mechanism 1 transports the medical needles 5, thereby ensuring the positional stability of the medical needles 5 during transport.

[0081] Example 8: Based on Example 7 above, in this example, as... Figure 1 Combination Figure 8As shown, the water-cutting device further includes a cleaning mechanism 7; the cleaning mechanism 7 is disposed between the second pressing component 6 and the sleeve mechanism 3; the cleaning mechanism 7 includes a cleaning plate 71, a second connecting plate 72, and an eighth driving member 73; the second connecting plate 72 is arranged in parallel with the conveying mechanism 1; the cleaning plate 71 is slidably disposed on the second connecting plate 72; there are two cleaning plates 71, and the two cleaning plates 71 are arranged sequentially from the upper end of the second connecting plate 72 to the lower end of the second connecting plate 72; wherein, a cleaning cotton 13 is disposed on the side of the two cleaning plates 71 that are close to each other; the eighth driving member 73 is disposed on the second connecting plate 72, and the eighth driving member 73 is connected to the cleaning plate 71; wherein, the eighth driving member 73 is used to drive the two cleaning plates 71 to move closer to each other, so as to clamp the needle body 51 of the medical needle 5 between the two cleaning cotton 13.

[0082] For example, in the implementation process, the above-mentioned water cutting device also includes a cleaning mechanism 7, which is disposed on the conveying path of the conveying mechanism 1 and is located between the second pressing component 6 and the sleeve mechanism 3.

[0083] The cleaning mechanism 7 includes a cleaning plate 71, a second connecting plate 72, and an eighth driving component 73. The second connecting plate 72 is connected to the support base 10 by welding, screwing, or other methods, and is arranged parallel to the conveying mechanism 1. One end of the cleaning plate 71 is slidably connected to the connecting plate via a guide rail and a slider, allowing the cleaning plate 71 to slide up and down along the connecting plate. Two cleaning plates 71 are provided, positioned opposite each other at the upper and lower ends of the connecting plate, and located on the upper and lower sides of the needle body 51 of the medical needle 5. Cleaning cotton 13 is provided on the side of each cleaning plate 71 that is close to each other. The cleaning cotton 13 can be made of materials with good absorbency and no lint, such as medical-grade clean cotton, microfiber, or foam.

[0084] The eighth drive unit 73 can be a cylinder, an electric actuator, or a servo linear module. The eighth drive unit 73 is connected to the second connecting plate 72 by welding, screwing, or other methods, and the output shaft of the eighth drive unit 73 is connected to both cleaning plates 71 to drive the two cleaning plates 71 to move closer or further apart.

[0085] The eighth driving component 73 includes a first driving unit 731 and a second driving unit 732. Both the first driving unit 731 and the second driving unit 732 are mounted on the second connecting plate 72. The upper cleaning plate 71 is connected to the output shaft of the first driving unit 731, and the lower cleaning plate 71 is connected to the output shaft of the second driving unit 732. The first driving unit 731 drives the upper cleaning plate 71 downward, and the second driving unit 732 drives the lower cleaning plate 71 upward, so that the two cleaning plates 71 move closer to or further apart.

[0086] During use, after the seventh drive unit 61 drives the second pressure plate 62 to press the needle handle 52 of the medical needle 5 into the first placement groove 2, the conveying mechanism 1 continues to convey the medical needle 5. When the needle body 51 of the medical needle 5 is conveyed by the conveying mechanism 1 between the two cleaning plates 71, the eighth drive unit 73 is operated to drive the two cleaning plates 71 closer together until the needle body 51 is clamped between the cleaning cotton 13 on the two cleaning plates 71. The cleaning cotton 13 tightly wraps the surface of the needle body 51, and the surface of the needle body 51 is cleaned by contact wiping. The aim is to effectively remove particles, grease, or hand contaminants that adhere during production and handling, thereby improving the cleanliness of the medical needle 5.

[0087] After cleaning is completed, the eighth drive unit 73 is operated first to drive the two cleaning plates 71 away from each other. Next, the delivery mechanism 1 is operated to send the cleaned medical needle 5 into the cannula mechanism 3.

[0088] In a preferred embodiment, the cleaning mechanism 7 further includes a limiting component 12, the structure of which is the same as that of the second pressing component 6.

[0089] During use, when the delivery mechanism 1 delivers the needle body 51 of the medical needle 5 between the two cleaning plates 71, the limiting component 12 is first made to adhere to the upper side of the needle handle 52 of the medical needle 5 in the first placement groove 2, and then the eighth drive component 73 is operated to drive the two cleaning plates 71 closer to each other. This aims to limit the needle handle 52 of the medical needle 5 using the limiting component 12, thereby reducing the risk of the needle handle 52 of the medical needle 5 slipping out of the first placement groove 2 during the cleaning process of the cleaning plates 71.

[0090] To facilitate the orderly and batch placement of multiple medical needles 5 into the first placement slot 2, the injection gates of the needle handles 52 of the multiple medical needles 5 are usually linearly connected during molding. Therefore, to facilitate the separation of the linearly connected multiple medical needles 5, Example 9: Based on Example 7 or Example 8 above, in this example, as... Figure 1 Combination Figure 9As shown, the cutting device further includes a cutting mechanism 8; the cutting mechanism 8 is disposed above the conveying mechanism 1, and the cutting mechanism 8 is disposed on the side of the sleeve mechanism 3 away from the second pressing component 6; the cutting mechanism 8 includes a ninth driving member 81 and a cutter 82; the cutter 82 is disposed above the conveying mechanism 1; the ninth driving member 81 is connected to the cutter 82; wherein, the ninth driving member 81 is used to drive the cutter 82 to move towards the conveying mechanism 1 to cut off the end of the needle handle 52 of the medical needle 5.

[0091] For example, in the implementation process, the above-mentioned water cutting device also includes a cutting mechanism 8, which is disposed above the conveying mechanism 1 and is located on the side of the sleeve mechanism 3 away from the second pressing component 6 (i.e., the downstream side of the sleeve mechanism 3).

[0092] The cutting mechanism 8 includes a ninth drive member 81 and a cutter 82. The ninth drive member 81 can be a cylinder, an electric actuator, or a servo linear module. The ninth drive member 81 is connected to the support base 10 via a support frame and is located above the conveying mechanism 1. The cutter 82 is located above the conveying mechanism 1 and is connected to the ninth drive member 81 by means of screwing, welding, or other methods. This allows the cutter 82 to move closer to the conveying mechanism 1 under the action of the ninth drive member 81.

[0093] During use, when the conveying mechanism 1 transports the medical needle 5 with the cannula 11 already in place to the area below the cutter 82, the ninth drive unit 81 is activated to drive the cutter 82 to cut downwards at high speed, thereby removing the excess injection gate at the end of the needle handle 52 that is away from the needle body 51. This is intended to achieve the separation of the medical needle 5.

[0094] Example 10: Based on Example 9 above, in this example, as... Figure 1 Combination Figure 10 As shown, the cutting nozzle device further includes a feeding mechanism 9; the feeding mechanism 9 is disposed on the side of the cutting mechanism 8 away from the sleeve mechanism 3, and the feeding mechanism 9 is arranged in parallel with the conveying mechanism; the feeding mechanism 9 includes a clamping member 91 and a tenth driving member 92; the clamping member 91 is arranged in parallel with the conveying mechanism, and the clamping member 91 is used to clamp the sleeve 11 on the medical needle 5; the tenth driving member 92 is connected to the clamping member 91; wherein, the tenth driving member 92 is used to drive the clamping member to remove the medical needle 5 from the first placement slot 2.

[0095] For example, in the implementation process, the above-mentioned water cutting device also includes a feeding mechanism 9, which is located on the side of the cutting mechanism 8 away from the sleeve mechanism 3, and the feeding mechanism 9 is connected to the conveying mechanism.

[0096] The unloading mechanism 9 includes a clamping component 91 and a tenth driving component 92. The tenth driving component 92 can be a cylinder, an electric actuator, or a servo linear module, and is connected to the support base 10 via a support frame. The clamping component 91 can be a pneumatic gripper, an electric gripper, a vacuum suction head, or an elastic clamp, and is connected to the tenth driving component 92 by means of screw fixing.

[0097] During operation, when the conveying mechanism 1 transports the medical needle 5, after it has been cut off by the cutting mechanism 8 at the injection gate, to below the clamping member 91, the tenth driving member 92 drives the clamping member 91 closer to the medical needle 5 and clamps the outer wall of the sleeve 11. After the clamping member 91 clamps the sleeve 11, the tenth driving member 92 drives the clamping member 91 away from the conveying mechanism 1 and places the medical needle 5 with the sleeve 11 into the target storage area. This aims to achieve automatic feeding, thereby reducing manual labor intensity and the risk of misplacement, omission, collision, or directional confusion caused by manual handling, ultimately improving subsequent packaging efficiency.
