Description
Technical Field
[0001] The present invention relates to the technical field of automated assembly of medical products, and in particular to a mechanism for assembling medical connecting necks. Background Art
[0002] A medical vacuum ball is a portable negative pressure device used for postoperative drainage and wound aspiration, primarily in surgical procedures and trauma care. Early vacuum drainage technology dates back to the mid-20th century and initially relied on electric or wall-mounted vacuum systems, which were bulky and dependent on a power source.
[0003] Since the 1980s, manual vacuum balls have gradually developed. Made of elastic silicone or PVC, they create negative pressure by squeezing out air, enabling portable drainage. Existing technologies incorporate one-way valves, backflow prevention devices, and standardized connectors (such as Luer connectors) to improve safety and adaptability.
[0004] At present, medical negative pressure balls have become a common device for postoperative drainage and are widely used in combination with modern dressings (such as VSD technology). Their technological development reflects the evolutionary trend from mechanical negative pressure to lightweight, low-cost and high reliability.
[0005] As a component of the medical negative pressure ball structure, the medical connecting neck plays a decisive role in the entire assembly process in actual production. After assembling three parts on the connecting neck separately, it is assembled into a whole with other parts. In traditional production, transportation is often achieved manually, and the operators need to wear dust-proof clothing, dust caps and masks. This results in low production efficiency, large assembly workload, serious assembly consistency differences, and high assembly contamination risks.
[0006] Therefore, how to provide a mechanism for automatically assembling medical connecting necks, improving assembly efficiency and precision while avoiding contamination has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention
[0007] The present invention provides a mechanism for assembling a medical connecting neck, which is used to solve the problem of how to provide a mechanism for assembling the medical connecting neck automatically, improving the assembly efficiency and precision, and avoiding contamination.

[0009] In some embodiments, the material taking mechanism includes: Fixed bracket; The linear module is installed on the top of the fixed bracket; Fixed plate A, connected to the output end of the linear module; Lifting cylinder, installed on fixed plate A; Fixed plate B, the top of which is connected to the output end of the lifting cylinder; Rotating cylinder, connected to the bottom of fixed plate B; The clamping cylinder is installed at the output end of the rotary cylinder and is used to clamp the connecting neck.
[0010] In some embodiments, a correction mechanism is further included, which is installed at the bottom of the rotating cylinder and is used to level the connecting neck.
[0011] In some embodiments, the correction mechanism includes: A fixed rod, one end of which is connected to the bottom of the rotating cylinder; A top plate, the top of which is connected to the other end of the fixing rod; a spring, one end of which is connected to the bottom of the top plate; The deviation-correcting pressure plate is connected to the other end of the spring.
[0012] In some embodiments, the direct vibration feeding mechanism includes: Adjustment plate; Straight vibrator, mounted on the adjustment plate; Balance weight, mounted on the adjustment plate; The material channel is installed on the top of the straight vibrator and the top of the balance block. The material channel is used to convey the connecting neck.
[0013] In some embodiments, a material sensor is installed on the material channel.
[0014] In some embodiments, the mismatch mechanism includes: Support frame; A mounting block, mounted on top of the support frame; Fixed plate C, installed on top of the mounting block; Slide cylinder, mounted on the mounting block; The staggered plate is connected to the output end of the slide cylinder, and the mounting block and the fixed plate C are both slidably connected to the staggered plate. Two groups of arc-shaped through grooves are opened on the surface of the staggered plate.
[0015] In some embodiments, an optical fiber sensor is mounted on the support frame, an optical fiber head is mounted on the staggered board, and the optical fiber head is electrically connected to the optical fiber sensor.
[0016] In some embodiments, the fixture mechanism includes: Jig holder; Telescopic cylinder, installed on the fixture bracket; A connecting neck clamping block is connected to the output end of the telescopic cylinder and is used to clamp the connecting neck; The lifting and positioning cylinder is installed at the bottom of the fixture bracket; The jig is placed on the output end of the jacking and positioning cylinder, and a placement groove for placing the connecting neck is opened on the jig, and a synchronous belt mechanism is arranged under the jig.
[0017] In some embodiments, the connecting neck clamp and the placement slot each include two groups.
[0018] The beneficial effects of the present invention are as follows: In a specific application, the present invention is a mechanism for assembling medical connecting necks. First, the connecting neck is conveyed to the material channel through an external vibration plate, and the straight vibrator vibrates to drive the connecting neck to move forward until the front connecting neck moves to one of the arc-shaped slots on the staggered plate. At this time, the slide cylinder is started, the staggered plate slides, and the other arc-shaped slot is aligned with the material channel. At this time, two groups of connecting necks are placed on the staggered plate, and then the linear module and the lifting cylinder are started at the same time, and the two groups of connecting necks are clamped by the clamping cylinder, and then the linear module, the lifting cylinder and the rotating cylinder cooperate to move the connecting neck to the connecting neck clamping block. When the clamping cylinder clamps the connecting neck, in order to avoid its deflection and causing falling and contamination, a correction pressure plate is provided in the present invention. In the process of the connecting neck moving toward the connecting neck clamping block, the correction pressure plate is under the elastic force of the spring. Under the action, the upper surface of the connecting neck is always pressed to keep it in a stable posture. After the connecting neck moves to the connecting neck clamping block, the connecting neck clamping block clamps the connecting neck under the action of the telescopic cylinder until the jig on the synchronous belt mechanism moves to just below the connecting neck clamping block. The jacking and positioning cylinder is started to lift the jig. At this time, the telescopic cylinder extends, and the connecting neck falls into the placement groove of the jig, and then the jacking and positioning cylinder contracts, and the jig falls onto the synchronous belt mechanism and continues to move forward, and then the two groups of connecting necks on it are processed for the next step. The mechanism for assembling medical connecting necks in the present invention does not require manual intervention, and two groups of connecting necks can be transported at a time, with high assembly efficiency. Due to the use of a variety of grooves for placing connecting necks and the use of a correction pressure plate for adjusting the posture, the technical solution in the present invention has stronger assembly consistency and no risk of contamination.

[0022] As described in the background technology, the medical connecting neck is a component of the medical negative pressure ball structure. In actual production, the connecting neck is assembled on the product according to the assembly requirements, which plays a decisive role in the entire assembly process. Three parts need to be assembled separately on the connecting neck, and then it is assembled with other parts into a whole. In traditional production, transportation is often achieved manually, and the operators need to wear dust-proof clothing, dust caps and masks to work. The production efficiency is low, the assembly workload is large, the assembly consistency differences are serious, and there are technical problems such as high assembly contamination risk.
[0023] To solve the above problems, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The present invention provides a mechanism for assembling a medical connecting neck, comprising a material picking mechanism 1, a straight vibration feeding mechanism 2, a staggered mechanism 3 and a jig mechanism 4. The straight vibration feeding mechanism 2 is arranged on one side of the material picking mechanism 1, and one end of the straight vibration feeding mechanism 2 is used to receive materials. One end of the staggered mechanism 3 is connected to the other end of the straight vibration feeding mechanism 2 for receiving materials transported by the straight vibration feeding mechanism 2. The jig mechanism 4 is connected to the other end of the staggered mechanism 3.
[0024] Specifically, the material picking mechanism 1 includes two groups of material picking claws, which can move two groups of connecting necks at a time. The direct vibration feeding mechanism 2 is a linear material conveying mechanism, which feeds the material picking mechanism 1, and the source of the direct vibration feeding mechanism 2 is a vibration disk. The connecting necks stored in the vibration disk are moved to the direct vibration feeding mechanism 2 for conveying in turn. Since the direct vibration feeding mechanism 2 is a linear conveying mechanism, the present invention is provided with a staggered mechanism 3 to adjust the position of the connecting neck and cooperate with the material picking mechanism 1 to pick up materials. After the material picking mechanism 1 completes the material picking, the two groups of connecting necks will be placed on the jig mechanism 4 for subsequent conveying.
[0025] Preferably, the material picking mechanism 1 includes: a fixed bracket 11, a linear module 12, a fixed plate A13, a lifting cylinder 14, a fixed plate B15, a rotating cylinder 16 and a clamping cylinder 17.

In order to prevent the connecting neck from being not straightened when clamped, resulting in falling, the present invention is provided with a correction pressure plate 184. The correction pressure plate 184 abuts against the top of the connecting neck under the action of the elastic force of the spring 183, so that it remains horizontal, thereby achieving an ideal clamping state and avoiding the occurrence of falling.

The straight vibrator 22 is installed on the adjustment plate 21, and the balancing block 23 is installed on the adjustment plate 21. The top of the straight vibrator 22 and the top of the balancing block 23 are installed with a material channel 24, and the material channel 24 is used to convey the connecting neck.
[0031] Specifically, the connecting neck moves on the vibrating material channel 24 generated by the straight vibrator 22. At the same time, in order to maintain the balance of the material channel during vibration, the present invention also provides a balance block 23. In addition, the adjustment plate 21 is a liftable plate, so that the height of the material channel 24 in the present invention is adjustable, which is suitable for implementation under various working conditions.

[0035] Specifically, the staggered plate 35 reciprocates under the drive of the slide cylinder 34, continuously aligning the material channel 24 with two groups of arc-shaped grooves, and each group of arc-shaped grooves is respectively placed with a group of connecting necks, and cooperates with the material taking mechanism 1 to realize uninterrupted connecting neck transportation.

A placement groove for placing the connecting neck is opened on the jig 45, and a synchronous belt mechanism 5 is provided below the jig 45.
[0039] Specifically, in the present invention, after the connecting neck moves to the connecting neck clamp 43, the connecting neck clamp 43 clamps the connecting neck under the action of the telescopic cylinder 42 to prevent it from falling down. When the jig 45 on the synchronous belt mechanism 5 moves to just below the connecting neck clamp 43, the jacking and positioning cylinder 44 is started to lift the jig 45. At this time, the jig 45 no longer moves with the synchronous belt mechanism 5. At this time, the telescopic cylinder 42 extends, and the connecting neck falls into the placement groove of the jig 45.
