Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a blood collection needle feeding device and its feeding method. Background Technology

[0002] In medical procedures, blood collection needles are frequently used for blood collection and testing. They consist of a needle tip, a needle hub, a catheter, and a connecting end. Current blood collection needle manufacturing often involves mass production, using horizontal or vertical placement with the needle hub facing down for loading. However, during the loading process, due to the small spacing between batches of blood collection needles, the needle hubs of vertically placed needles easily become tangled together, requiring operators to spend time tidying them up, which is labor-intensive. Horizontal placement not only makes the needles difficult to handle due to gravity but also requires operators to pre-position the needles to avoid them becoming tangled during handling, affecting processing speed. Therefore, a blood collection needle loading device and its loading method are needed. Summary of the Invention

[0003] To address the problems existing in the prior art, the purpose of this invention is to provide a blood collection needle feeding device and its feeding method, which can prevent blood collection needles from tangling together, achieve orderly feeding in batches, and improve the processing efficiency of blood collection needles.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a blood collection needle feeding device and a feeding method thereof, comprising a frame, a picking mechanism for picking up blood collection needles is provided on the side of the frame near the conveying mechanism, a first moving clamp and a second moving clamp for moving blood collection needles are provided on the top of the frame, a conveying mechanism for organizing blood collection needles is provided on the side of the frame, a transmission mechanism for conveying blood collection needles is provided on the side of the frame away from the conveying mechanism, and a temporary storage mechanism for storing blood collection needles is provided on the frame between the picking mechanism and the transmission mechanism.

[0005] In some embodiments, the conveying mechanism includes a support frame, a buffer rod is provided on the support frame, a feeding frame is provided on the buffer rod, and a vibrator is provided at the bottom of the feeding frame.

[0006] In some embodiments, the unloading frame includes a conveying trough, a guide plate is provided on the conveying trough, and a limit frame is provided on the unloading frame above the guide plate.

[0007] In some embodiments, a stop bar is provided at one end of the guide plate near the material handling mechanism.

[0008] In some embodiments, a baffle is provided on the side of the conveying trough near the material handling mechanism.

[0009] In some embodiments, the temporary storage mechanism includes a mounting frame, on which a misaligned storage component is disposed, and on the side of the mounting frame near the misaligned storage component a leveling component is disposed, the leveling component including a cylinder, and a push plate disposed on the telescopic part of the cylinder.

[0010] In some embodiments, the misaligned storage assembly includes an electric push rod, a horizontal plate is provided on the telescopic part of the electric push rod, a storage plate is provided on the horizontal plate, and a sliding member is provided between the horizontal plate and the mounting frame.

[0011] In some embodiments, multiple horizontal plates and storage plates are provided, and connecting members are provided between each pair of the multiple horizontal plates. The connecting members include sliding plates and sliding rods.

[0012] In some embodiments, the transmission mechanism is a transmitter, and the transmitter is provided with a placement clip.

[0013] A method for feeding blood collection needles, using the aforementioned equipment, includes the following steps:

[0014] 1. The operator places a batch of blood collection needles vertically in the feeding frame with both wings facing upwards, so that the wings of the blood collection needles are on the guide plate, and then starts the vibrator to transport the blood collection needles to the frame.

[0015] 2. A batch of blood collection needles that have been vibrated to the side of the frame are picked up by the material handling mechanism and flipped to a horizontal position. Then, the horizontal blood collection needles are transferred to the storage plate of the temporary storage mechanism by the first moving clamp.

[0016] 3. Use electric push rods to adjust the spacing of the storage plates to reduce the distance between batches of blood collection needles, and use leveling components to align the positions of the batches of blood collection needles.

[0017] Fourth, control the second moving clamp to transfer the batch of blood collection needles located on the temporary storage mechanism to the transmission mechanism, while the first moving clamp transfers the next batch of blood collection needles to the temporary storage mechanism. Repeat this process to complete the feeding of blood collection needles.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The present invention is equipped with a conveying mechanism. By changing the orientation of the blood collection needle, the needle seat end of the blood collection needle is placed on the conveying groove with the needle seat end facing upward. The blood collection needle is vibrated by a vibrator to ensure that the blood collection needle moves stably and orderly. This not only avoids the needle seat ends of the blood collection needles from getting tangled together, but also makes it easier for operators to place the needles, increases the conveying speed of the blood collection needles, and improves processing efficiency.

[0020] 2. A temporary storage mechanism is also provided. The staggered temporary storage mechanism can not only adjust the distance between the blood collection needles placed on it, but also ensure that the blood collection needles correspond to the positions of the placement clips, save the transmission position of the transmitter, increase the number of blood collection needles conveyed on the transmission mechanism, and increase the processing output of blood collection needles.

[0021] 3. The present invention utilizes the cooperation between the first moving clamp, the material picking and flipping mechanism, the temporary storage mechanism, and the second moving clamp to change the transmission state of the blood collection needle. At the same time, the first and second moving clamps, together with the temporary storage mechanism, serve as transfer points to achieve batch-by-batch, uninterrupted, and orderly feeding. The entire process is automatic and requires no manual operation, making it convenient and fast. Attached Figure Description

A conveying mechanism 2 for organizing blood collection needles is provided on the side of the frame 1. A transmission mechanism 6 for conveying blood collection needles is provided on the side of the frame 1 away from the conveying mechanism 2.

[0035] In some embodiments, the conveying mechanism 2 includes a support frame 21, a buffer rod 22 is provided on the support frame 21, a feeding frame 23 is provided on the buffer rod 22, and a vibrator is provided at the bottom of the feeding frame 23.

[0036] In some embodiments, the unloading frame 23 includes a conveying trough 234, and eight conveying troughs 234 are provided. Each of the eight conveying troughs 234 is provided with a guide plate 231, and a limiting frame 232 is provided on the unloading frame 23 above each of the eight guide plates 231.

[0037] In some embodiments, each of the eight guide plates 231 is provided with a stop bar 2311 near one end of the material handling mechanism 3.

[0038] In some embodiments, each of the eight conveying channels 234 is provided with a baffle 233 on the side near the material handling mechanism 3.

[0039] In some embodiments, the temporary storage mechanism 4 includes a mounting frame 41, on which a misaligned storage component 42 is provided, and on the side of the mounting frame 41 near the misaligned storage component 42 a leveling component 43 is provided, the leveling component 43 includes a cylinder 431, and a push plate 432 is provided on the telescopic part of the cylinder 431. There are eight push plates 432, and the ends of the eight push plates 432 are all provided with a conical surface 4321.

[0040] In some embodiments, the misaligned storage assembly 42 includes an electric push rod 421, a horizontal plate 422 is provided on the telescopic part of the electric push rod 421, a storage plate 423 is provided on the horizontal plate 422, and a sliding member 426 is provided between the horizontal plate 422 and the mounting bracket 41.

[0041] In some embodiments, multiple horizontal plates 422 and storage plates 423 are provided, and connecting members are provided between each pair of horizontal plates 422. The connecting members include sliding plates 425 and sliding rods 424.

[0042] In some embodiments, the transmission mechanism 6 is a transmitter, and the transmitter is provided with placement clips 61. The placement clips 61 are arranged in groups of eight and are intermittently disposed on the transmitter.

[0043] Working principle: First, the operator places the blood collection needle 8 with its wing ends facing upwards into the conveying groove 234, ensuring the wing ends are positioned above the guide plate 231. The guide plate 231 guides the sequential conveying of the batch of blood collection needles 8. Simultaneously, the limiting frame 232 limits the ends of the blood collection needles 8, preventing interference between the ends of the blood collection needles 8 in the eight conveying grooves 234 of the feeding frame 23. Next, the vibrator is activated for vibration conveying. The vibrated blood collection needles 8 move to the end of the feeding frame 23 closest to the frame 1. The wing ends of the blood collection needles 8 are blocked by the stop bar 2311, preventing the rapid movement of the blood collection needles 8 due to vibration from causing the material handling mechanism 3 to fail to grasp them in time and fall, thus affecting the processing efficiency of the blood collection needles. The needle seat of the blood collection needle 8... The needle 8 is blocked by the baffle 233 to prevent the needle holder from being unable to be gripped by the material-picking mechanism 3 due to inertial swing after being blocked by the baffle 2311. Then the material-picking mechanism 3 starts to pick up the needle. The force applied by the material-picking mechanism 3 can ensure that the needle 8 breaks through the blockage of the baffle 2311 and the baffle 233. The baffle 233 is directly connected to the feeding frame 23 by a torsion spring, which can quickly reset. Then the material-picking mechanism 3 clamps and flips the eight needles 8 so that all eight needles 8 are in a horizontal position. The material-picking mechanism 3 is the existing flipping material-picking clamp, which will not be described in detail here. After the material-picking mechanism 3 clamps the needles 8, it controls the first moving clamp 5 to move all eight needles 8 to the temporary storage mechanism 4. The horizontal plate 422 and the storage plate 423 are both provided with eight needles, and the two Each electric push rod 421 is connected to a horizontal plate 422 on one side to control the movement of the eight horizontal plates 422 and the storage plates 423. Three sets of eight storage plates 423 are arranged as a group to fix blood collection needles 8 of different lengths. Shorter blood collection needles 8 are fixed by two sets of storage plates 423, while longer ones are fixed by three sets of storage plates 423. Then, controlling the retraction of two electric push rods 421 causes the eight horizontal plates 422 to move closer together through the sliding action of the sliding rods 424 via the sliding plate 425. This reduces the distance between the blood collection needles 8 on the eight storage plates 423, ensuring that the position of the eight blood collection needles 8 corresponds to the position of the placement clamp 61. This saves space for the transmitter, increases the processing capacity of the blood collection needles 8, and places the blood collection needles 8 into the temporary storage mechanism via the first moving clamp 5. When the needles are in place, the control cylinder 431 contracts, causing the push plate 432 to move towards the end of the blood collection needle 8 away from the needle holder. Then, the push plate 432 uses its conical surface 4321 to align the end of the blood collection needle 8 away from the needle holder, ensuring that the eight blood collection needles 8 are of uniform length. This facilitates subsequent unified operation, avoids wasting materials due to defective products during subsequent testing, and reduces production output. After the first moving clamp 5 places the blood collection needle 8 onto the temporary storage mechanism 4, it resets and clamps the next batch of blood collection needles 8. At this time, the second moving clamp 7 moves simultaneously with the first moving clamp 5 to clamp eight blood collection needles 8. As the first moving clamp 5 transports the next batch of blood collection needles 8 to the temporary storage mechanism 4, the second moving clamp 7 simultaneously moves the previous batch of blood collection needles 8 directly above the transmission mechanism 6, allowing the placement clamp 61 to fix the eight blood collection needles 8 in place.This process is repeated to achieve batch feeding of the blood collection needles 8. The entire process can be automated, either manually controlled or pre-programmed by an existing system. Finally, the fed blood collection needles 8 are transported to the next processing step via the conveyor mechanism 6.

[0044] A method for feeding blood collection needles, using the aforementioned equipment, includes the following steps:

[0045] 1. The operator places a batch of blood collection needles 8 in a vertical position with their wings facing upwards in the feeding frame 23, so that the wings of the blood collection needles 8 are on the guide plate 231, and then starts the vibrator to transport the blood collection needles 8 to the frame 1.

[0046] 2. A batch of blood collection needles 8 that have been vibrated to the side of the frame 1 are picked up by the material handling mechanism 3 and flipped to a horizontal state. Then, the horizontal blood collection needles 8 are transferred to the storage plate 423 of the temporary storage mechanism 4 by the first moving clamp 5.

[0047] 3. The spacing of the storage plates 423 is adjusted by using the electric push rod 421 to reduce the distance between the batch of blood collection needles 8, and the position of the batch of blood collection needles 8 is aligned by using the leveling component 43.

[0048] Fourth, control the second moving clamp 7 to transfer the batch of blood collection needles 8 located on the temporary storage mechanism 4 to the transmission mechanism 6, while the first moving clamp 5 transfers the next batch of blood collection needles 8 to the temporary storage mechanism 4, and repeat this process to complete the feeding of blood collection needles 8.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
