Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, specifically to an ultrasonic welding device for syringe filter needle holders. Background Technology

[0002] A syringe filter cartridge is a single-use filter cartridge routinely used to remove particulates from liquids used in sample preparation processes, such as in high-performance liquid chromatography (HPLC), ion chromatography, or dissolution tests. In other cases, the syringe filter can be attached to a syringe to remove particulates during subcutaneous injection.

[0003] Syringe filter needle holders typically contain a filter membrane. To prevent leakage, the needle holder and filter membrane are usually welded together as a single unit to ensure filter quality. Due to the irregular shape of syringe filter needle holders, manual loading and unloading are often required during production. This results in low welding efficiency and poses safety hazards due to manual handling of the needle holders. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] (1) Through the setting of the feeding mechanism, the needle seat will roll along the side wall of the guide port after being guided by the guide port. When the needle seat rolls to the discharge groove position, the needle seat may roll directly out of the discharge groove or may get stuck inside the discharge groove. Through the setting of the rotating seat, the rotating seat rotates, which facilitates feeding and also drives the needle seat stuck inside the discharge groove to rotate, thus avoiding the situation of blockage in the discharge groove. In this way, the needle seat can be automatically fed, avoiding the need for manual feeding.

[0021] (2) The needle seat of the present invention will roll along the guide rod to the welding auxiliary plate due to gravity. Due to the shape of the needle seat itself, its center of gravity is not directly above the welding auxiliary plate. The needle seat will tilt and fall into the cylindrical hole, and after being guided by the tilt angle, it will fall directly above the welding auxiliary cylinder, which is convenient for welding. Then the welding module works, pushes the welding head down, and works with the welding auxiliary cylinder to press the needle seat tightly, so that ultrasonic welding can be performed.

[0022] (3) By setting up the welding auxiliary plate, the partition plate will block the subsequent needle seat during welding, so that it is stored in the guide rod. After welding is completed, the lifting seat can automatically pop out the welded needle seat by using inertia, thus realizing automatic unloading. Furthermore, by setting up the guide slope, the needle seat will be guided, preventing the needle seat from falling back onto the welding auxiliary cylinder, which facilitates the smooth progress of subsequent welding operations.

[0023] (4) After the automatic feeding of the present invention, the partition will move up and lose its blocking effect on the needle seat. The next needle seat to be welded will move into the welding auxiliary plate again to perform the next welding action. This avoids the situation where the needle seats need to be placed on the work station one by one manually, which results in low welding efficiency. It also avoids the safety hazards of manual feeding.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0049] Example 2

[0050] See also Figure 4 - Figure 8 As shown, a pair of fixed seats 5101 are symmetrically fixedly connected to the top of the first mounting housing 51 near the feeding box 2.

[0053] Using the ladder platform 64, the electric telescopic rod 53 extends, and the side wall of the ladder platform 64 contacts the first limiting seat 612 on the bottom opening 611, pushing the movable blocks 66 on both sides away from each other, so that the welding auxiliary plate 7 can be moved up and reset.

[0054] Example 3

[0055] See also Figure 9 - Figure 10 As shown, a partition plate 71 is fixedly connected to the top of the welding auxiliary plate 7 near the side of the feeding box 2. Two insert plates 72 are symmetrically fixedly connected to the bottom of the welding auxiliary plate 7. The insert plates 72 are slidably set inside the corresponding opening 611. A horizontal plate 721 is fixedly connected to the middle of the insert plate 72. A limiting seat 722 is symmetrically fixedly connected to the bottom of the horizontal plate 721. A spring 73 is sleeved on the limiting seat 722. The bottom of the spring 73 is sleeved on the corresponding first limiting seat 612. A second limiting seat 74 is fixedly connected to the bottom of the insert plate 72. Limiting slots 741 are opened on the two symmetrical side walls of the second limiting seat 74.

[0056] A mounting bracket 75 is fixedly installed between two second limiting seats 74. Slide rods 76 are slidably installed at both ends of the mounting bracket 75. Circular plate 761 and circular plate 762 are fixedly connected to the middle and bottom of the slide rod 76, respectively. The mounting bracket 75 is located between circular plate 761 and circular plate 762. A lifting seat 77 is fixedly installed on the top of each slide rod 76. Guide slopes 771 are provided on the sides of the two lifting seats 77 that are far apart from each other. The lifting seats 77 are located inside the welding auxiliary cylinder 6. Springs 78 are provided between the top of circular plate 762 and the mounting bracket 75. Springs 78 are sleeved on the slide rod 76.

[0057] When the welding auxiliary plate 7 moves to the top, the pusher seat 77 will continue to move upward due to inertia, the spring 4 78 will be compressed, and the pusher seat 77 will pop out the welded needle seat. Furthermore, the guide slope 771 will guide the needle seat, preventing it from falling back onto the welding auxiliary cylinder 6, thus facilitating the smooth progress of subsequent welding operations.

[0058] In use, the assembled filter needle holders to be welded are placed inside the feed funnel 22. The motor 41 is started to drive the rotating seat 4 to rotate. When the rotating seat 4 rotates, the needle holders will fall between the arc plates 44 through the setting of the arc plates 44, and then fall onto the top of the rotating seat 4 through the discharge port 45. Guided by the guide port 31, the needle holders roll along the side wall of the guide port 31. When the needle holders roll to the discharge trough 32, the housing of the needle holders may be stuck inside the discharge trough 32. At this time, the needle holders can roll directly along the discharge trough 32 and be guided by the guide rod 5102 to the end of the guide rod 5102. Alternatively, the end connector of the needle holders may be stuck inside the discharge trough 32. At this time, as the rotating seat 4 rotates, the connector on the other side of the needle holders will be stuck inside the groove 42, which will drive the needle holders stuck inside the discharge trough 32 to rotate, thus avoiding the discharge trough 32 from being blocked. This can realize automatic feeding of needle holders and avoid the need for manual feeding.

[0059] Afterwards, the needle holder will roll along the guide rod 5102 to the top of the welding auxiliary plate 7 and stay on the top of the welding auxiliary plate 7. Then, due to the shape of the needle holder itself, its center of gravity is not directly above the welding auxiliary plate 7. The needle holder will tilt and fall into the cylindrical hole 511 and fall above the welding auxiliary cylinder 6 through the guide angle 512. Then the welding module 12 works, pushing the welding head 13 to move down, and cooperates with the welding auxiliary cylinder 6 to press the needle holder and perform the welding action.

[0060] During this process, the welding head 13 will press the welding auxiliary cylinder 6 downward through the needle seat, and the base plate 61, the insertion rod 62 and the movable plate 63 will move downward simultaneously. The spring 65 will be compressed, and the welding auxiliary plate 7 will move downward simultaneously. When the welding auxiliary cylinder 6 moves to the bottom, the limiting block 661 located at the top of the movable block 66 will just fit into the limiting slot 741.

[0061] When welding is completed, welding head 13 moves upward, spring 65 rebounds, pushing welding auxiliary cylinder 6 upward, while limit block 661 has a limiting effect on second limit seat 74, welding auxiliary plate 7 stays at the bottom, and spring 73 is in a compressed state.

[0062] When the welding auxiliary cylinder 6 returns to its original position and the welding head 13 retracts, the electric telescopic rod 53 extends and pushes the movable plate 63, the insertion rod 62, the base plate 61 and the welding auxiliary cylinder 6 upward again. The side wall of the ladder 64 contacts the first limiting seat 612 on the bottom opening 611, pushing the movable blocks 66 on both sides away from each other until the limiting block 661 disengages from the limiting slot 741. The spring 73 rebounds and pushes the welding auxiliary plate 7 upward to reset. When the welding auxiliary plate 7 moves to the top, the lifting seat 77 will continue to move upward due to inertia. The spring 78 is compressed, and the lifting seat 77 will pop out the welded needle seat. Through the setting of the guide slope 771, it will guide the needle seat and prevent the needle seat from falling back onto the welding auxiliary cylinder 6.

[0063] During the ejection of the completed needle holder, the next needle holder will move into the welding auxiliary plate 7 again due to the upward movement of the partition 71, thus losing its blocking effect on the needle holder. Then, the next welding action will be performed again. This avoids the situation where the needle holders need to be placed on the work station one by one, which results in low welding efficiency, and also avoids the safety hazards of manual material loading.
