Description

Technical Field

[0001] The invention relates to the technical field of medical device production, in particular to ultrasonic welding equipment for a syringe filter needle seat. Background Art

[0002] Syringe filter needle seats are single-use filter cartridges that are routinely used to remove particulates from liquids used in sample preparation processes such as high performance liquid chromatography (HPLC) analysis, ion chromatography analysis, or dissolution testing. In other cases, syringe filters can be connected to syringes to remove particulates during subcutaneous injections.

[0003] A filter membrane is generally provided inside the syringe filter needle seat. To avoid leakage of the filter membrane, the needle seat and the filter membrane generally need to be welded into a whole to ensure the quality of the filter. Due to the irregular shape of the syringe filter needle seat, most of the syringe filter needle seats are manually loaded and unloaded during production, which results in low welding production efficiency of the syringe filter needle seat. In addition, the syringe filter needle seat is manually taken and placed on the work station, which poses certain safety hazards. Summary of the invention

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

[0020] (1) The present invention sets a feeding mechanism. Through the guiding effect of the guide port, the needle seat will roll along the side wall of the guide port. When the needle seat rolls to the position of the discharge slot, the needle seat may directly roll out of the discharge slot or may get stuck inside the discharge slot. By setting the rotating seat, the rotating seat rotates, which not only facilitates the discharge of materials, but also drives the needle seat stuck inside the discharge slot to rotate, thus avoiding the blockage of the discharge slot. 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 fall into the cylindrical hole and fall directly above the welding auxiliary tube after being guided by the inclination angle, which is convenient for welding. After that, the welding module will work, push the welding head downward, and cooperate with the welding auxiliary tube to press the needle seat, so that ultrasonic welding can be carried out.

[0022] (3) The present invention arranges a welding auxiliary plate. During welding, the partition will block the subsequent needle seat 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 inertia to achieve automatic unloading. In addition, the setting of the guide slope will guide the needle seat to prevent the needle seat from falling back onto the welding auxiliary cylinder, thereby facilitating the smooth progress of subsequent welding actions.

[0023] (4) After the automatic unloading of the present invention, the partition moves up and loses 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, avoiding the need to manually place the needle seats on the work station one by one, which leads to low welding efficiency, and avoids the safety hazards of manual loading.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Example 3

[0055] See also Fig. 9 - Fig.10 As shown, a partition plate 71 is fixedly connected to the top of the welding auxiliary plate 7 near the side of the loading box 2, and two plug plates 72 are symmetrically fixedly connected to the bottom of the welding auxiliary plate 7. The plug plates 72 are respectively slidably set inside a corresponding opening 611, and a cross plate 721 is fixedly connected to the middle of the plug plate 72.

The bottom of the plug plate 72 is fixedly connected to the limit seat 1 74, and limit slots 741 are provided on the symmetrical side walls of the limit seat 1 74.

[0056] A mounting frame 75 is fixedly installed between the two limit seats 1 74, and sliding rods 76 are slidably installed at both ends of the mounting frame 75. The middle part of the sliding rod 76 and the bottom of the sliding rod 76 are respectively fixedly connected with a circular plate 1 761 and a circular plate 2 762. The mounting frame 75 is located between the circular plate 1 761 and the circular plate 2 762. A push seat 77 is fixedly installed on the top of the sliding rod 76. A guide inclined surface 771 is provided on the side of the two push seats 77 away from each other. The push seat 77 is arranged inside the welding auxiliary cylinder 6. A spring 4 78 is arranged between the top of the circular plate 2 762 and the mounting frame 75, and the spring 4 78 is sleeved on the sliding rod 76.

[0057] When the welding auxiliary plate 7 moves to the top, the push seat 77 will continue to move upward due to inertia, the spring four 78 will be compressed, and the push seat 77 will pop out the welded needle seat, and through the setting of the guide bevel 771, it will have a guiding effect on the needle seat to prevent the needle seat from falling back onto the welding auxiliary cylinder 6, thereby facilitating the smooth progress of subsequent welding actions.

[0058] When in use, the assembled filter needle seat to be welded is placed inside the feed funnel 22, and the motor 41 is started to drive the rotating seat 4 to rotate. When the rotating seat 4 rotates, the needle seat will fall between the arc plates 44 through the setting of the arc plate 44, and then fall on the top of the rotating seat 4 through the drop opening 45. Guided by the guide opening 31, the needle seat rolls along the side wall of the guide opening 31. When the needle seat rolls to the position of the discharge slot 32, the shell of the needle seat may be stuck in the discharge slot 32. At this time, the needle seat can directly roll along the discharge slot 32 and be guided by the guide rod 5102 to roll to the end of the guide rod 5102. It is also possible that the end connector of the needle seat is stuck in the discharge slot 32. At this time, as the rotating seat 4 rotates, the connector on the other side of the needle seat will be stuck in the groove 42, which will drive the needle seat stuck in the discharge slot 32 to rotate, avoiding the blockage of the discharge slot 32. In this way, automatic loading of the needle seat can be realized, avoiding the need for manual loading.

[0059] Afterwards, the needle seat 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. Afterwards, due to the shape of the needle seat itself, its center of gravity is not directly above the welding auxiliary plate 7, and the needle seat will fall into the cylindrical hole 511, and fall above the welding auxiliary cylinder 6 under the guidance of the inclination angle 512. Afterwards, the welding module 12 works, pushes the welding head 13 downward, cooperates with the welding auxiliary cylinder 6 to press the needle seat, and performs welding.

[0060] During this process, the welding head 13 will move down through the needle seat to squeeze the welding auxiliary cylinder 6, the bottom plate 61, the insertion rod 62 and the movable plate 63 will move down synchronously, the spring 1 65 will be compressed, and the welding auxiliary plate 7 will move down synchronously. When the welding auxiliary cylinder 6 moves to the bottom, the limit block 661 located at the top of the movable block 66 is just stuck in the limit card slot 741.

[0061] When welding is completed, the welding head 13 moves upward, the spring 1 65 rebounds, and pushes the welding auxiliary cylinder 6 to move upward, and the limit block 661 has a limiting effect on the limit seat 1 74, the welding auxiliary plate 7 stays at the bottom, and the spring 3 73 is in a compressed state;

[0062] When the welding auxiliary cylinder 6 returns to its original position and the welding head 13 is retracted, the electric telescopic rod 53 extends and pushes the movable plate 63, the insertion rod 62, the bottom plate 61 and the welding auxiliary cylinder 6 upward again, and the side wall of the ladder 64 contacts the limit seat 1 612 on the opening 611 at the bottom, pushing the movable blocks 66 on both sides away from each other until the limit block 661 is disengaged from the inside of the limit slot 741, and the spring 3 73 rebounds, pushing the welding auxiliary plate 7 to move up and reset. When the welding auxiliary plate 7 moves to the top, the push seat 77 will continue to move up due to inertia, and the spring 4 78 will be compressed. The push seat 77 will eject the welded needle seat, and the setting of the guide slope 771 will have a guiding effect on the needle seat to prevent the needle seat from falling back onto the welding auxiliary cylinder 6;

[0063] During the process of the needle seat popping out after welding, the next needle seat will lose its blocking effect on the needle seat due to the upward movement of the partition 71, and move again to the inside of the welding auxiliary plate 7, and then perform the next welding action again, avoiding the need to manually place the needle seat on the work station one by one, resulting in low welding efficiency, and avoiding the safety hazards of manual loading.
