Technical Field

[0001] The utility model relates to the technical field of soft needle seat assembly, in particular to a guide mechanism that facilitates the assembly of the soft needle seat. Background Art

[0002] Infusion extension tubing is a tubular device used in the medical field to connect infusion sets and other medical equipment. Its primary function is to provide additional length during infusion, making it easier for medical staff to operate. The soft needle hub is the soft portion at the end of the extension tubing, which is typically used to connect to a needle or other infusion device. Assembly of the soft needle hub is a critical step in the production of infusion extension tubing, requiring it to be assembled onto the flexible tube.

[0003] In the traditional production process, the method of assembling the soft needle seat on the hose is usually manual and relies on manual operation. This method has the following disadvantages:

[0004] Low production efficiency: Manual assembly is slow, and operators need to spend more time to complete each step. Especially in large-scale production, production efficiency is significantly lower than that of automated or semi-automated methods;

[0005] Poor quality consistency: During manual assembly, fluctuations in operator skill and condition can affect assembly quality, leading to poor product consistency and the possibility of deviations or defective products.

[0006] High labor intensity: Operators need to perform manual operations continuously, and long hours of work can easily lead to accumulated fatigue, which in turn affects production efficiency and quality;

[0007] High operational complexity: Each assembly step requires the operator to operate carefully, especially the process of aligning and inserting the soft needle seat, which requires high attention and meticulous operation, increasing the complexity of the operation.

[0008] Therefore, there is a particular need for a guide mechanism that is convenient for assembling the soft needle seat to solve the above problems. Utility Model Content

[0011] Furthermore, the clamping assembly includes a first cylinder, a clamping block, a rotating block, a slider and a support rod. The first cylinder is installed on the left side of the top of the base, and the first cylinder is located below the discharge plate. The upper right side of the support frame is fixedly connected to the support rod distributed front and back, and the slider is slidably connected to the outside of the support rod. The upper and lower sides of the slider are rotatably connected to the rotating blocks, and the clamping block is rotatably connected between the two transversely aligned rotating blocks.

[0014] Furthermore, the unloading plate and the unloading rack are provided with the same number of placement slots.

[0015] Furthermore, the bottom of the positioning plate is designed to be a curved surface.

[0016] From the above description of the structure of the present invention, it can be seen that the design starting point, concept and advantages of the present invention are:

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example: A guide mechanism for assembling a soft needle holder, see Figures 1-4As shown, it includes a base 1, a support frame 2, a discharge plate 3, a clamping assembly, a fixed frame 9, an electric slide rail 10, an electric slide rod 11, a discharge rack 12, a pushing assembly and a positioning assembly. The base 1 is located at the bottom layer and serves as the support of the entire mechanism. The left side of the top of the base 1 is connected to the support frame 2 by welding. The upper part of the support frame 2 is connected to the discharge plate 3 by bolts for placing the hose. A clamping assembly for clamping the hose is provided between the base 1 and the support frame 2. The top of the base 1 is connected to the fixed frame 9 by bolts, and the fixed frame 9 is located below the discharge plate 3. The fixed frame The left side of the upper part of 9 is connected to an electric slide rail 10 distributed front and back by bolts, and an electric slide rod 11 is slidably connected between the two electric slide rails 10. The electric slide rod 11 is connected to a discharge rack 12 by bolts for placing the soft needle seat. The discharge plate 3 and the discharge rack 12 are provided with a same number of placement slots, and each placement slot of the discharge plate 3 is aligned one by one with each placement slot of the discharge rack 12 to ensure that the soft needle seat is aligned with the hose. A pushing component for pushing the soft needle seat is provided on the fixed frame 9, and a positioning component for accurately positioning the soft needle seat is provided between the fixed frame 9 and the discharge rack 12.

[0025] See Figure 2 As shown, the clamping assembly includes a first cylinder 4, a clamping block 5, a rotating block 6, a slider 7 and a support rod 8. The first cylinder 4 is connected to the left side of the top of the base 1 by bolts. The first cylinder 4 is located below the discharge plate 3. The upper right side of the support frame 2 is connected to the support rod 8 distributed front and back by welding. The slider 7 is slidably connected to the outside of the support rod 8. The rotating blocks 6 are rotatably connected to the upper and lower sides of the slider 7. The clamping block 5 is rotatably connected between the two transversely aligned rotating blocks 6, and a rubber pad is provided on the clamping surface of the clamping block 5 to enhance the clamping effect. The telescopic rod of the first cylinder 4 is fixedly connected to the lower clamping block 5.

[0026] See Figure 1 and Figure 3 As shown, the pushing assembly includes a second cylinder 13, a push plate 14 and a push rod 15. The second cylinder 13 is connected to the right side of the upper part of the fixed frame 9 by bolts, and the push plate 14 is connected to the telescopic rod of the second cylinder 13 by welding. A plurality of push rods 15 distributed longitudinally are connected to the left side of the push plate 14 by welding. Each push rod 15 is aligned with each placement slot of the material rack 12 one by one, and the center of the push rod 15 is opposite to the center of the placement slot of the material rack 12, so that the soft needle seat can be pushed accurately.

[0027] See Figure 3-Figure 4As shown, the positioning assembly includes an inclined block 16, a positioning plate 17 and a spring 18. The inclined block 16 is connected to the left middle position of the upper part of the fixed frame 9 by welding, and the positioning plate 17 is slidably connected to the left side of the discharge rack 12. The inclined block 16 is against the positioning plate 17, and the bottom of the positioning plate 17 is designed as an arc surface, so that when it contacts the inclined block 16, the pressure can be more evenly distributed on the contact surface instead of being concentrated at a certain point, ensuring that the positioning plate 17 can move upward smoothly when squeezed by the inclined block 16. The right side of the positioning plate 17 is provided with a symmetrically distributed spring 18, and the two ends of the spring 18 are respectively connected to the discharge rack 12 and the positioning plate 17.

[0028] Initially, the spring 18 is in a compressed state. When the soft needle seat needs to be assembled, the operator first places multiple hoses in the placement grooves on the discharge plate 3, and places multiple soft needle seats in the placement grooves on the discharge rack 12. When placing the soft needle seat, the positioning plate 17 plays a positioning role, which facilitates the rapid and accurate placement of the soft needle seat. Then, the first cylinder 4 is turned on to control its telescopic rod to extend to the appropriate length, driving the lower clamping block 5 to rise until the lower clamping block 5 contacts the bottom surface of the right end of the hose. During this process, the lower clamping block 5 pushes the lower rotating block 6 to rotate, and the lower rotating block 6 pushes the slider 7 to slide outward along the support rod 8, and the slider 7 pulls the upper rotating block 6 to rotate, and the upper rotating block 6 pulls the upper clamping block 5 down to contact the top surface of the right end of the hose, so that it cooperates with the lower clamping block 5 to clamp the right end of the hose, ensuring that the right end of the hose is stable and motionless during the assembly process. After the clamping is completed, turn on the electric slide rail 10, control the electric slide rod 11 to drive the discharge rack 12 to slide to the left along the set trajectory until the soft needle seat contacts the right end of the hose. During this process, the discharge rack 12 drives the positioning plate 17 to slide to the left and disengage from the inclined block 16, and the spring 18 then Restore to its original state, prompting the positioning plate 17 to move downward so that the soft needle seat can contact the right end of the hose without obstruction, and then turn on the second cylinder 13, control its telescopic rod to extend to the appropriate length, drive the push rod 15 to move to the left, until the push rod 15 pushes the soft needle seat into the right end of the hose, so that the soft needle seat is assembled. After the assembly is completed, control the telescopic rod of the second cylinder 13 to retract, drive the push rod 15 to move to the right and reset, control the electric slide bar 11 to drive the material rack 12 to slide to the right along the set trajectory and reset. In this process, the material rack 12 drives the positioning plate 17 to the right The sliding contact inclined block 16 causes the positioning plate 17 to be squeezed upward and reset along the inclined surface of the inclined block 16, and the spring 18 is compressed accordingly, controlling the telescopic rod of the first cylinder 4 to retract, driving the lower clamping block 5 to descend and reset. During this process, the lower clamping block 5 pulls the lower rotating block 6 to reverse, and the lower rotating block 6 pulls the slider 7 to slide inward along the support rod 8. The slider 7 pushes the upper rotating block 6 to reverse, and the upper rotating block 6 pushes the upper clamping block 5 to rise and reset. Finally, the multiple assembled infusion extension tubes are removed from the discharge plate 3 and prepared for the next assembly cycle.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
