Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an outer tube assembly machine. Background Technology

[0002] The catheters or other accessories of blood bags often need to be inserted through an outer tube and then sealed by heat fusion or ultrasonic welding to achieve specific functions. The traditional assembly method is mainly manual operation, in which workers manually align the outer tube with the end of the fitting and apply pressure to complete the insertion. Manual assembly has the following drawbacks: (1) Due to the limited skill of workers, the production efficiency is low and it is difficult to meet the needs of mass production; (2) Uneven pressure during manual application can easily lead to gaps or misalignment between the outer tube and the catheter, resulting in poor consistency and affecting the welding quality; (3) The catheter is mostly made of flexible plastic, and manual positioning can easily lead to deviation of the insertion angle due to tube deformation, reducing the yield rate.

[0003] Therefore, there is an urgent need for an automated device specifically designed for assembling the outer sheath of blood collection bags to solve the challenges of efficiency, accuracy, and compatibility. Utility Model Content

[0006] Preferably, the first clamp, the second clamp, and the slide can all be electrically driven or pneumatically driven.

[0007] Preferably, the upper surface of the table is provided with a blood bag limiting groove, and the blood bag limiting groove matches the shape of the blood bag.

[0008] Preferably, the upper surface of the table is provided with an outer sleeve limiting groove, and the arrangement direction of the outer sleeve limiting groove is consistent with the moving direction of the slide.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] In the embodiments, such as Figures 1-3 The diagram shows an outer tube assembly machine, comprising: a table 1, serving as a platform for placing the outer tube 10 and blood bag 11; a first clamp 2 and a second clamp 3, arranged side-by-side with their clamping centers aligned, extending upward from the table 1, respectively used to clamp the outer tube 10 and the docking fitting 12 on the blood bag 11; and a slide 4, installed below the table 1, used to drive the first clamp 2 to slide back and forth along the axial direction of the outer tube 10. This embodiment achieves high-precision positioning of the outer tube 10 and the docking fitting 12 through a double-clamp center alignment design. Combined with the axial sliding of the first clamp 2 driven by the slide 4, it realizes automatic alignment and insertion of the outer tube 10 and the docking fitting 12 on the blood bag 11, resulting in small positional deviations, high operational accuracy, and high production efficiency.

[0034] In the embodiments, such as Figure 3 As shown, the first clamp 2, the second clamp 3, and the slide 4 can all be electrically driven or pneumatically driven. Servo motor-driven electric clamps or linear slides offer high position control accuracy and are suitable for products requiring high-precision assembly; pneumatically driven clamps have a fast response time, and the clamping force can be controlled by a pneumatic pressure regulating valve, making them suitable for products made of different materials.

[0035] In the embodiments, such as Figure 1 , Figure 2 As shown, the upper surface of the platform 1 is provided with a blood bag limiting groove 101, which matches the shape of the blood bag 11. The limiting groove 101 adopts a contour-following design, which is suitable for blood bags 11 of specific specifications, and prevents the blood bag 11 and docking accessories 12 from shifting during operation.

[0036] In the embodiments, such as Figure 1 , Figure 2 As shown, the upper surface of the platform 1 is provided with an outer tube limiting groove 102, and the arrangement direction of the outer tube limiting groove 102 is consistent with the moving direction of the slide table 4. The limiting groove 102 is a semi-circular groove or V-shaped groove structure, which matches the diameter of the outer tube 10 to ensure accurate positioning of the outer tube 10.

[0037] In the embodiments, such as Figure 3As shown, the jaws of the first clamp 2 are arc-shaped to match the shape of the outer tube 10, and the jaws of the second clamp 3 are arc-shaped to match the shape of the docking accessory 12. The arc-shaped jaws of the first clamp 2 and the second clamp 3 are adapted to the shapes of the outer tube 10 and the docking accessory 12, respectively. With the contour constraints of the outer tube limiting groove 102 and the blood bag limiting groove 101, the outer tube 10 and the docking accessory 12 are effectively fixed, avoiding tube twisting and deformation caused by operation and reducing insertion angle error.

[0038] In the embodiments, such as Figure 1 , Figure 2 As shown, the system also includes a housing 5, with a cover forming a platform 1. A display panel 6 and rotary switches 7 are mounted on the rear side of the housing 5. The display panel 6 shows parameters such as the second clamp 3 clamping the docking accessory 12, the first clamp 2 clamping the outer sleeve 10, the slide 4 driving the outer sleeve 10 forward, the first clamp 2 releasing, the slide 4 retracting, the second clamp 3 releasing, and the number of times the slide 4 advances. It also displays real-time product quantity, historical data, and fault codes. The visualized parameters on the display panel effectively reduce misoperation and enable information management of finished product production. The two rotary switches 7 serve as a voltage switch and a debugging switch, respectively, and are each equipped with an indicator light.

[0039] In the embodiments, such as Figure 1 , Figure 2 As shown, the front of the housing 5 is equipped with an emergency stop button 8 and two operation buttons 9. The two operation buttons 9 are connected in series and are arranged on both sides of each other. This embodiment is a semi-automatic device. Pressing both operation buttons 9 simultaneously completes the entire processing steps for one product. The two operation buttons 9 are far apart, requiring two hands to operate them, thus avoiding injury to the operator from the first clamp 2 and the second clamp 3.

[0040] The operation steps of the outer tube assembly machine in this embodiment are as follows:

[0041] Step 1. Preparation: Place the blood bag 11 into the blood bag limiting groove 101, ensuring that the docking accessory 12 is located in the center of the jaws of the second clamp 3; place the outer tube 10 into the outer tube limiting groove 102.

[0042] Step 2. Automatic clamping and insertion: Press the two operation buttons 9 with both hands respectively. The second clamp 3 and the first clamp 2 clamp the docking accessory 12 and the outer tube 10 in sequence. The slide table 4 drives the first clamp 2 to advance along the axis and insert according to the preset stroke. When the insertion depth and insertion force reach the set value, the slide table 4 stops automatically.

[0043] Step 3. Retraction: The first clamp 2 releases the outer sleeve 10, the slide 4 drives the first clamp 2 to retract axially, and the second clamp 3 engages with the accessory 12;

[0044] Step 4. Repeat steps 2 and 3 two to three times to complete the processing of one product;

[0045] Step 5. Cyclic Production: Take out the assembled blood bag 11 and repeat steps 1-4 for a new round of production and processing.

[0046] Step 6. Equipment maintenance: Clean the table surface 1 before starting and after turning off the machine each day, and check the wear of the clamps; regularly check the guide rails of the slide table 4 and check the air circuit sealing.

[0047] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
