Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, specifically a clamping structure for welding infusion connectors. Background Technology

[0002] Infusion connectors are key components that connect the infusion tubing and needle during intravenous infusion. Depending on the application and function, they can be categorized into sealing type, standard type, filtering type, and multi-way infusion connectors. The main function of an infusion connector is to connect the infusion set to the syringe, ensuring unidirectional or bidirectional flow of the fluid. Needle-free infusion connectors are an important component of needle-free infusion systems. By eliminating the need for a steel needle to puncture the rubber stopper, needle-free injection systems can maintain a sealed infusion channel after disconnection. This design is particularly suitable for patients requiring long-term infusion therapy, such as children, the elderly, critically ill patients, and chemotherapy patients.

[0003] According to Chinese Patent CN118417675A, an ultrasonic assembly and welding device for needleless connectors is proposed. When using the device, the needleless connectors to be processed are placed in the material holes of the processing tray in sequence. At this time, the power is turned on and the stepper motor runs. With each rotation, the cylinder pushes the push rod downward once. At the same time, the push rod pushes the lifting cylinder downward. When the transducer is powered on, the vibrator at the bottom achieves high-frequency vibration, which is transmitted to the welding head position by the vibrating plate to perform the welding process on the needleless connector.

[0004] However, there are still some shortcomings in this patent. In the process of welding the needleless connector, the needleless connector is placed on the top of the processing tray and welded by the welding head. However, due to the centrifugal force during the rotation of the processing tray, the needleless connector on the top is easily thrown outward, causing the position of the needleless connector to shift, thus affecting the welding effect of the device. To address this, we propose a clamping structure for welding infusion connectors. Utility Model Content

[0005] The purpose of this invention is to provide a clamping structure for welding infusion connectors, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping structure for welding infusion connectors, comprising a base and a clamping assembly disposed on the top of the base. The clamping assembly includes a drive motor fixedly connected to the bottom of the inner wall of the base. An output shaft is fixedly connected to the output end of the drive motor. A first gear is fixedly connected to the top outer wall of the output shaft. A second gear meshes with the side wall of the first gear.

An adjusting block is fixedly connected to the outer wall of one end of the screw, and a clamping plate is rotatably connected to the other end of the screw. A U-shaped block is slidably connected to the outer wall of the clamping plate. The bottom of the U-shaped block is fixedly connected to the top of the circular plate, and a rubber block is fixedly connected to the side wall of the clamping plate. By setting up the clamping assembly, it is convenient to clamp and fix the infusion connector through the clamping plate, thereby improving the stability during the welding of the infusion connector.

[0007] Preferably, the top of the base is further provided with a welding assembly, which includes an L-shaped plate fixedly connected to the top of the base, a cylinder fixedly connected to the top of the inner wall of the L-shaped plate, a displacement frame fixedly connected to the output end of the cylinder, a limit block fixedly connected to the side wall of the displacement frame, a limit post slidably connected to the inner wall of the limit block, and the top of the limit post fixedly connected to the top of the inner wall of the L-shaped plate. By providing the welding assembly, it is convenient to move the displacement frame up and down, thereby adjusting the welding height of the infusion connector.

[0008] Preferably, the welding assembly further includes a forward and reverse motor fixedly connected to the outer wall of the displacement frame. The output end of the forward and reverse motor is fixedly connected to a lead screw. The lead screw movably passes through the outer wall of the displacement frame and extends into the interior of the displacement frame. A sleeve block is threadedly connected to the outer wall of the lead screw. An ultrasonic welding device is also fixedly connected to the bottom of the sleeve block. A welding head is fixedly connected to the bottom of the ultrasonic welding device. By setting the ultrasonic welding device and the welding head, it is convenient to perform welding processing on the surface of the infusion connector.

[0009] Preferably, the bottom of the base is fixedly connected to four support legs of equal size. The four support legs are fixedly connected at equal intervals at the four corners of the bottom of the base. By setting four support legs, it is easy to achieve stable support for the base.

[0010] Preferably, the outer wall of the screw is threadedly connected to the inner wall of the arc-shaped block, one end of the outer wall of the screw is fixedly connected to the inner wall of the adjusting block, and the other end of the screw is rotatably connected to the side wall of the clamping plate. By setting the adjusting block, the screw and the clamping plate, it is easy to move the clamping plate along with the screw during rotation, thereby achieving clamping and fixing of the infusion connector during welding.

[0011] Preferably, there are several U-shaped blocks, all of equal size, and the U-shaped blocks are arranged in a circumferential array along the central axis of the driven shaft. By setting multiple U-shaped blocks, it is convenient to place the infusion connector that needs to be welded.

[0012] Preferably, the outer wall of the limiting post is adapted to the inner wall of the limiting block, and the side wall of the limiting block is fixedly connected to the side wall of the displacement frame.

[0013] Preferably, there are two limiting posts, the two limiting posts are of equal size, and the two limiting posts are symmetrically distributed along the center plane of the L-shaped plate.

[0014] This invention provides a clamping structure for welding infusion connectors. This clamping structure for welding infusion connectors has the following advantages:

[0015] (1) The clamping structure for welding the infusion connector, by setting the clamping component, before welding the infusion connector, in order to improve the stability of welding the infusion connector, it is necessary to clamp and fix the infusion connector. At this time, the operator places the infusion connector on the top of the circular plate and makes the outer wall of the infusion connector fit against the inner wall of the U-shaped block. Then, by rotating the adjusting block, the screw is rotated. During the rotation of the screw, the clamping plate is moved. After the clamping plate moves, the rubber block is squeezed against the infusion connector, thereby clamping and fixing the infusion connector and improving the stability of welding the infusion connector. When it is necessary to weld other infusion connectors on the top of the circular plate, the operator turns on the drive motor to make the output shaft rotate. After the output shaft rotates, the first gear rotates and meshes with the second gear, causing the driven shaft to rotate. After the driven shaft rotates, the circular plate rotates, which facilitates the welding of other infusion connectors on the top of the circular plate.

[0016] (2) The clamping structure for welding the infusion connector, by setting up the welding components, after the infusion connector is fixed, the operator opens the cylinder to cause the output end of the cylinder to extend and push the displacement frame to move downward, thereby facilitating the adjustment of the welding height on the surface of the infusion connector. During the downward movement of the displacement frame, the limiting block will slide down along the outer wall of the limiting column, thereby facilitating the limiting of the displacement frame during the downward movement and making the displacement frame move smoothly. After the welding height of the infusion connector is adjusted, the operator starts the ultrasonic welding equipment to cause the welding head to weld the infusion connector. When it is necessary to weld other positions on the surface of the infusion connector, the operator turns on the forward and reverse motor to cause the lead screw to rotate. During the rotation of the lead screw, the sleeve block will move laterally along its outer wall, thereby facilitating the adjustment of the welding position on the surface of the infusion connector.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] A preferred embodiment of the clamping structure for welding infusion connectors provided by this utility model is, for example... Figures 1 to 6 As shown: A clamping structure for welding infusion connectors includes a base 1 and a clamping assembly 31 disposed on the top of the base 1. The clamping assembly 31 includes a drive motor 311 fixedly connected to the bottom of the inner wall of the base 1. An output shaft 312 is fixedly connected to the output end of the drive motor 311. A first gear 313 is fixedly connected to the top outer wall of the output shaft 312. A second gear 314 meshes with the side wall of the first gear 313. A driven shaft 315 is fixedly connected to the inner wall of the second gear 314. The bottom outer wall of the driven shaft 315 is connected to the bottom of the inner wall of the base 1 via a bearing. The driven shaft 315 is rotatably connected to a circular plate 316 fixedly connected to its top. An arc-shaped block 317 is fixedly connected to the top side of the circular plate 316. A screw 318 is threadedly connected to the inner wall of the arc-shaped block 317. An adjusting block 3110 is fixedly connected to the outer wall of one end of the screw 318. A clamping plate 319 is rotatably connected to the other end of the screw 318. A U-shaped block 3111 is slidably connected to the outer wall of the clamping plate 319. The bottom of the U-shaped block 3111 is fixedly connected to the top of the circular plate 316. A rubber block 3112 is fixedly connected to the side wall of the clamping plate 319. The mechanism is designed to allow for... Before welding the infusion connector, the clamping assembly 31 is used to clamp and fix the connector to improve its stability during welding. The operator places the connector on top of the circular plate 316, ensuring the outer wall of the connector fits against the inner wall of the U-shaped block 3111. Then, by rotating the adjusting block 3110, the screw 318 rotates. During this rotation, the clamping plate 319 moves, causing the rubber block 3112 to press against the infusion connector. This allows for clamping and fixing of the infusion connector, improving stability during welding. When welding other infusion connectors on the top of the circular plate 316 is required, the operator turns on the drive motor 311, causing the output shaft 312 to rotate. After the output shaft 312 rotates, it causes the first gear 313 to rotate and mesh with the second gear 314, causing the driven shaft 315 to rotate. After the driven shaft 315 rotates, it causes the circular plate 316 to rotate, facilitating the welding of other infusion connectors on the top of the circular plate 316.

[0026] A preferred embodiment of the clamping structure for welding infusion connectors provided by this utility model is, for example... Figures 1 to 6As shown: A welding assembly 32 is also provided on the top of the base 1. The welding assembly 32 includes an L-shaped plate 321 fixedly connected to the top of the base 1. A cylinder 322 is fixedly connected to the top of the inner wall of the L-shaped plate 321. A displacement frame 323 is fixedly connected to the output end of the cylinder 322. A limit block 325 is fixedly connected to the side wall of the displacement frame 323. A limit post 326 is slidably connected to the inner wall of the limit block 325. The top of the limit post 326 is fixedly connected to the top of the inner wall of the L-shaped plate 321. By setting the welding assembly 32, after the infusion connector is fixed, the operator opens the cylinder 322 to cause the output end of the cylinder 322 to extend and push the displacement frame 323 to move downward, thereby facilitating the adjustment of the welding height on the surface of the infusion connector. During the downward movement of the displacement frame 323, it will slide the limit block 325 along the outer wall of the limit post 326, thereby facilitating the limitation of the displacement frame 323 during the downward movement and making the displacement frame 323 move smoothly.

[0027] The welding assembly 32 also includes a reversible motor 324 fixedly connected to the outer wall of the displacement frame 323. A lead screw 327 is fixedly connected to the output end of the reversible motor 324. The lead screw 327 movably passes through the outer wall of the displacement frame 323 and extends into the interior of the displacement frame 323. A sleeve block 328 is threadedly connected to the outer wall of the lead screw 327. An ultrasonic welding device 329 is fixedly connected to the bottom of the sleeve block 328. A welding head 3210 is fixedly connected to the bottom of the ultrasonic welding device 329. After the welding height of the infusion connector is adjusted, the operator starts the ultrasonic welding device 329 to cause the welding head 3210 to weld the infusion connector. When welding is required on other parts of the infusion connector surface, the operator turns on the reversible motor 324 to cause the lead screw 327 to rotate. During the rotation of the lead screw 327, the sleeve block 328 will move laterally along its outer wall, thereby facilitating the adjustment of the welding position on the surface of the infusion connector.

[0028] Furthermore, the bottom of the base 1 is fixedly connected with four support legs 2. The four support legs 2 are of equal size and are fixedly connected at the four corners of the bottom of the base 1 at equal intervals. By setting four support legs 2, it is easy to achieve stable support for the base 1.

[0029] Furthermore, the outer wall of the screw 318 is threadedly connected to the inner wall of the arc-shaped block 317, one end of the outer wall of the screw 318 is fixedly connected to the inner wall of the adjusting block 3110, and the other end of the screw 318 is rotatably connected to the side wall of the clamping plate 319. By setting the adjusting block 3110, the screw 318 and the clamping plate 319, it is convenient to move the clamping plate 319 with the screw 318 during rotation, thereby achieving clamping and fixing of the infusion connector during welding.

[0030] Furthermore, there are several U-shaped blocks 3111, all of equal size, and the U-shaped blocks 3111 are arranged in a circular array along the central axis of the driven shaft 315. By setting multiple U-shaped blocks 3111, it is convenient to place the infusion connector that needs to be welded.

[0031] Furthermore, the outer wall of the limiting post 326 is adapted to the inner wall of the limiting block 325, and the side wall of the limiting block 325 is fixedly connected to the side wall of the displacement frame 323.

[0032] In addition, there are two limit posts 326, which are of equal size and are symmetrically distributed along the center plane of the L-shaped plate 321.

[0033] Working principle: Before welding the infusion connector, to improve the stability during welding, the connector needs to be clamped and fixed. The operator places the connector on top of the circular plate 316, ensuring the outer wall of the connector fits against the inner wall of the U-shaped block 3111. Then, by rotating the adjusting block 3110, the screw 318 rotates. During the rotation of the screw 318, the clamping plate 319 moves. After the clamping plate 319 moves, the rubber block 3112 presses against the infusion connector, thereby... This mechanism clamps and fixes the infusion connector, improving stability during welding. When welding other infusion connectors on the top of the circular plate 316 is required, the operator turns on the drive motor 311, causing the output shaft 312 to rotate. After the output shaft 312 rotates, it causes the first gear 313 to rotate and mesh with the second gear 314, causing the driven shaft 315 to rotate. After the driven shaft 315 rotates, it causes the circular plate 316 to rotate, thus facilitating the welding of other infusion connectors on the top of the circular plate 316.

[0034] After the infusion connector is fixed, the operator opens the cylinder 322, causing the output end of the cylinder 322 to extend and push the displacement frame 323 downward, so as to facilitate the adjustment of the welding height on the surface of the infusion connector. During the downward movement of the displacement frame 323, the limiting block 325 will slide down along the outer wall of the limiting post 326, so as to facilitate the limiting of the displacement frame 323 during the downward movement and make the displacement frame 323 move smoothly.

[0035] After adjusting the welding height of the infusion connector, the operator starts the ultrasonic welding equipment 329 to cause the welding head 3210 to weld the infusion connector. When welding is required on other parts of the infusion connector surface, the operator turns on the forward and reverse motor 324 to cause the lead screw 327 to rotate. During the rotation of the lead screw 327, the sleeve block 328 will move laterally along its outer wall, which makes it easier to adjust the welding position on the surface of the infusion connector.

[0036] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
