Description

Technical Field

[0001] This invention relates to the technical field of catheters, and more specifically, to a method for side-by-side spiral welding of two catheters for connecting joints. Background Technology

[0002] Catheters often need to be assembled with connectors to form catheters with connectors at the ends. Generally, the ends of the catheter are inserted into the connectors to achieve the assembly of the catheter and connectors.

[0003] In the manufacturing industry, for certain specific needs, it is necessary to connect two conduits to a connector. The connector has two insertion sections, and the ends of the two conduits need to be connected to the two insertion sections respectively.

[0004] In the prior art, after the two conduits are respectively connected to the connector, during the packaging process, in order to better package the conduits, the two conduits need to be arranged in a spiral shape so that they can be stored in the packaging bag. In addition, the two conduits need to be welded together to prevent the spiral conduits from coming loose.

[0005] However, the current method of manually welding the double conduits with connectors is difficult to automate, which reduces manufacturing efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a method for parallel spiral welding of two conduits in a connector, which aims to solve the problem that in the prior art, it is difficult to achieve automatic spiral welding of two conduits in a connector.

[0007] This invention is implemented as follows: a method for parallel spiral welding of two conduits in a connecting joint includes the following steps:

[0008] 1) The head end of the conduit is inserted into the connector, and the tail end of the conduit is freely arranged; the rotating disk has a rotating station and a welding station; the rotating disk is provided with a rotating disk, and the rotating disk has two rotating grooves, which are arranged in the same direction on the top of the rotating disk.

[0009] A robotic arm is used to clamp the connector with two conduits onto a rotating plate on the rotating station, with the ends of the two conduits embedded in the outer end of the rotating groove.

[0010] 2) During the rotation of the rotating disk, the two conduits are pressed down from top to bottom by the downward pressing structure so that the two conduits are embedded in the rotating groove and are embedded along the rotating direction of the rotating groove until the tail end of the conduit is embedded in the rotating groove.

[0011] 3) The rotating disk rotates, and the disk with the embedded conduit is rotated to the welding station. The welding head is used to weld between the two conduits to form a welding point. The welding point connects the two conduits into one piece, and the two conduits form a finished product in a spiral shape.

[0012] Furthermore, the top of the two spiraling grooves forming the spiraling disk, the outer ends of the two spiraling grooves converge and connect to form an open groove, and the inner ends of the spiraling grooves are arranged spirally toward the center of the spiraling disk.

[0013] In step 1), when the tip of the catheter is embedded in the outer end of the spiral groove, the connector is placed in the opening groove.

[0014] Furthermore, the opening groove is provided with two clamping heads that move towards or away from each other. In step 1), when the connector is placed in the opening groove, the two clamping heads move towards each other to clamp and fix the connector.

[0015] Furthermore, the connector has two insertion sections, which are arranged at an oblique intersection with an oblique gap between them, and the tips of the two conduits are inserted into the insertion sections.

[0016] The opening groove is provided with a positioning wall, and the two clamping heads are respectively located on both sides of the positioning wall; in step 1), after the connector is placed in the opening groove, the positioning wall passes through the inclined interval.

[0017] Furthermore, along the rotation direction of the rotating disk, a discharge station is provided in front of the welding station; in step 3), after the welding head completes the welding of the two guide tubes, the rotating disk rotates the disc to the discharge station, and the discharge structure is used to remove the finished part from the disc groove from bottom to top.

[0018] Furthermore, the rotating disk includes a base arranged in a horizontal rotational manner, the base being rotatably connected to the rotating disk, the base being provided with a detachable disk body, the disk body being detachably connected to the base by bolts, and two rotating grooves being provided on the disk body.

[0019] Furthermore, the discharge structure includes multiple through-hole groups arranged vertically through the rotating disk, the multiple through-hole groups being arranged at intervals along the circumference of the disk body, and the through-hole groups extending radially along the rotating disk; each through-hole group includes multiple through holes that penetrate vertically through the rotating disk, the bottom of the through holes penetrating the bottom of the rotating disk, and the top of the through holes penetrating to the bottom of the rotating groove.

[0020] The bottom of the disc body is provided with multiple lifting shaft groups that correspond to the through hole group vertically. The lifting shaft groups are arranged vertically aligned with the through hole group. Each lifting shaft group includes multiple lifting shafts that can move vertically.

[0021] In step 3), after the swivel rotates to the discharge station, the multiple lifting shafts move upward through the through hole and abut against the bottom of the finished product from bottom to top, thus disengaging the guide tube from the swivel groove.

[0022] Furthermore, the rotating disk is provided with a through groove, which extends radially along the disk body; the bottom of the through groove penetrates the bottom of the disk body, and the top of the through groove penetrates to the bottom of the rotating groove; the bottom of the disk body is provided with a lifting plate that moves up and down, and the lifting plate is arranged vertically aligned with the through groove.

[0023] In step 3), when the swivel rotates to the discharge position, the lifting plate moves upward and passes through the through groove, abutting the finished part from bottom to top, and detaching the finished part from the swivel groove.

[0024] Furthermore, a material receiving head is provided above the material discharge station, and the material receiving head has two swing blades in the middle. There are upper plates on both sides of the material receiving head. When the two swing blades swing downward to their limit position, the swing blades are arranged facing each other in a longitudinal arrangement. When the two swing blades swing upward to their limit position, the two swing blades are separated from each other in a horizontal position. The swing blades are located below the upper plates and have a clamping gap with the upper plates.

[0025] The finished part has a hollow area in the middle. In step 3), when the finished part is detached from the swivel groove, the material taking head moves toward the swivel part, the two swing blades are arranged longitudinally, and after passing through the hollow area, the two swing blades swing upward to the limit position and become horizontal, clamping the swivel part horizontally in the clamping interval.

[0026] Furthermore, the pressing structure includes a pressing plate that moves up and down, the pressing plate having a downwardly arranged pressing surface, the pressing surface being recessed upward to form a recessed groove with an open bottom; the top of the recessed groove is formed with a spirally arranged upper guide groove, the upper guide groove being spirally arranged along the spiraling direction of the spiral groove.

[0027] The recessed groove is filled with an elastic layer, and the bottom of the elastic layer extends out to form a bottom opening, forming a pressing part. A hollowed-out deformation interval is formed between the top of the elastic layer and the top of the recessed groove. The elastic layer has a spirally arranged lower guide groove, and the upper guide groove and the lower guide groove are aligned and connected vertically.

[0028] The pressure plate is connected to a telescopic shaft. The upper end of the telescopic shaft moves through the lower guide groove and the upper guide groove respectively, and is movably connected to the upper guide groove. The lower end of the telescopic shaft extends to the bottom of the elastic layer and is connected to a horizontally rotating rotating head.

[0029] In step 2), as the rotating disk rotates, the rotating head presses against the two conduits from top to bottom, and the rotating head rotates synchronously with the rotating disk to embed the two conduits into the two rotating grooves. The pressing part presses against the top of the rotating disk downwards to prevent the conduits from coming out of the rotating grooves.

The spiraling disk rotates, and a pressing structure is used to press the conduits into the spiraling grooves. As the spiraling grooves spiral, a welding head is used to form a welding point between the two conduits, thereby forming the two conduits into a single finished product. This method automates the spiral welding of two conduits, is convenient to spiral, and has high manufacturing efficiency. Attached Figure Description

[0041] Reference Figure 1-7 The image shows a preferred embodiment of the present invention.

[0042] The method for side-by-side spiral welding of the double conduits 300 connecting joint 500 includes the following steps:

[0043] 1) The head end of the conduit 300 is inserted into the connector 500, and the tail end of the conduit 300 is freely arranged; the rotating disk 400 has a rotating station 401 and a welding station 402; the rotating disk 400 is provided with a rotating disk 200, and the rotating disk 200 has two rotating grooves 101, which are arranged in the same direction on the top of the rotating disk 200.

[0044] The connector 500, which is connected to two conduits 300, is clamped onto the rotating plate 200 on the rotating station 401 using a robotic arm, and the head ends of the two conduits 300 are embedded in the outer end of the rotating groove 101.

[0045] 2) During the rotation of the rotating disk 400, the rotating disk 200 uses the downward pressing structure to press the two conduits 300 from top to bottom, so that the two conduits 300 are embedded in the rotating groove 101 and are embedded along the rotating direction of the rotating groove 101 until the tail end of the conduit 300 is embedded in the rotating groove 101.

[0046] 3) Rotating the rotating disk 400 rotates the rotating disk 200 with the embedded conduit 300 to the welding station 402. The welding head 500 is used to weld between the two conduits 300 to form a welding point. The welding point connects the two conduits 300 into one piece, and the two conduits 300 form a finished part in a spiral shape.

[0047] The above-mentioned method for parallel spiral welding of the two conduits 300 in the connecting joint 500 involves arranging a spiraling disk 200 with two spiraling grooves 101. After the heads of the two conduits 300 are embedded in the two spiraling grooves 101, the spiraling disk 200 rotates, and the downward pressing structure presses the conduits 300 into the spiraling grooves 101. As the spiraling grooves 101 spiral, the welding head 500 forms a welding point between the two conduits 300, thus forming the two conduits 300 into a single finished product. This method automates the spiral welding of the two conduits 300, making spiraling convenient and increasing manufacturing efficiency.

[0048] Multiple welding points are formed between the two conduits 300, and these welding points are arranged at intervals along the spiral direction of the conduits 300, which makes the two conduits 300 form a more stable integrated structure.

[0049] In this embodiment, the top of the rotating disk 200 formed by the two rotating grooves 101 is connected at the outer ends of the two rotating grooves 101 to form an open groove 106, and the inner ends of the rotating grooves 101 are arranged to rotate toward the center of the rotating disk 200.

[0050] In step 1), when the tip of the conduit 300 is embedded in the outer end of the spiral groove 101, the connector 500 is placed in the opening groove 106, thereby fixing the position of the connector 500 so that the tip of the conduit 300 can be embedded in the outer end of the spiral groove 101.

[0051] In this embodiment, the opening groove 106 is provided with two clamping heads 105 that move towards or away from each other. In step 1), after the connector 500 is placed in the opening groove 106, the two clamping heads 105 move towards each other to clamp and fix the connector 500. In this way, the ends of the two coiled conduits 300 can be fixed, avoiding phenomena such as detachment during the coiling process.

[0052] The connector 500 has two insertion sections 501, which are arranged at an angle and intersecting each other. There is an angled gap between the two insertion sections 501. The heads of the two conduits 300 are inserted into the insertion sections 501. A positioning wall is provided in the opening groove 106, and two clamping heads 105 are located on both sides of the positioning wall. In step 1), after the connector 500 is placed in the opening groove 106, the positioning wall passes through the angled gap.

[0053] In this way, the positioning wall is passed through the inclined gap, and the connector 500 is clamped by two clamping heads 105 facing each other, so that the connector 500 is fixed in the opening groove 106.

[0054] In this embodiment, along the rotation direction of the rotating disk 400, a discharge station 403 is provided in front of the welding station 402; in step 3), after the welding head 500 completes the welding of the two guide tubes 300, the rotating disk 400 rotates the swivel disk 200 to the discharge station 403, and uses the discharge structure to remove the finished part from the swivel groove 101 from bottom to top.

[0055] After the finished parts are separated from the spiral groove 101 by the discharge structure, the finished parts are arranged horizontally and spirally, forming an integral structure, so that the finished parts can be placed in the packaging bag.

[0056] In this embodiment, the rotating disk 200 includes a horizontally rotatable base, which is rotatably connected to the rotating disk 400. A detachable disk body 100 is provided on the base, and the disk body 100 is detachably connected to the base by bolts. Two rotating grooves 101 are provided on the disk body 100. Thus, when the rotating grooves 101 are damaged, the disk body 100 can be directly replaced.

[0057] The discharge structure includes multiple through holes arranged vertically through the rotating disk 200. The multiple through holes are arranged at intervals along the circumference of the disk body 100 and extend radially along the rotating disk 200. The through hole group includes multiple through holes 104 that penetrate vertically through the rotating disk 200. The bottom of the through hole 104 penetrates the bottom of the rotating disk 200, and the top of the through hole 104 penetrates to the bottom of the rotating groove 101.

[0058] The bottom of the disc 100 is provided with multiple lifting shaft groups that correspond to the through hole group above and below. The lifting shaft groups are arranged vertically aligned with the through hole group. The lifting shaft group includes multiple lifting shafts that can move up and down. In step 3), when the disc 200 rotates to the discharge station 403, the multiple lifting shafts move upward and pass through the through hole 104, abutting the bottom of the finished part from bottom to top, and disengaging the guide tube 300 from the disc groove 101.

[0059] By arranging multiple through-hole groups and corresponding multiple lifting shaft groups, the finished product in a spiral shape can be lifted at multiple positions to achieve horizontal and uniform force distribution, thus freeing the finished product from the spiral groove 101.

[0060] In this embodiment, the rotating disk 200 is provided with a through groove 103, which extends radially along the disk body 100; the bottom of the through groove 103 penetrates the bottom of the disk body 100, and the top of the through groove 103 penetrates to the bottom of the rotating groove 101; the bottom of the disk body 100 is provided with a lifting plate that moves up and down, and the lifting plate is aligned vertically with the through groove 103.

[0061] In step 3), after the rotating disc 200 rotates to the discharge station 403, the lifting plate moves upward and passes through the through groove 103, abutting the finished part from bottom to top, and detaching the finished part from the rotating groove 101. In this way, with the cooperation of multiple lifting shaft groups, the finished part can be lifted in a staggered position, and during the lifting process, the entire radial lifting of the guide tube 300 is achieved, so that the guide tube 300 is axially stretched during the lifting process of the finished part.

[0062] In this embodiment, a material picker is provided above the material discharge station 403. The material picker has two swing blades 601 in the middle and upper plates 600 on both sides of the material picker. When the two swing blades 601 swing downward to their limit position, the swing blades 601 are arranged facing each other in a longitudinal arrangement. When the two swing blades 601 swing upward to their limit position, the two swing blades 601 are separated from each other in a horizontal position. The swing blades 601 are located below the upper plate 600 and have a clamping gap 602 between them.

[0063] The finished part has a hollow area in the middle. In step 3), when the finished part is detached from the swivel groove 101, the material take-up head moves toward the swivel part, the two swing blades 601 are arranged longitudinally, and after passing through the hollow area, the two swing blades 601 swing upward to the limit position and become horizontal, clamping the swivel part horizontally in the clamping interval 602.

[0064] After the finished part is detached from the rotating plate 200, the two swing plates 601 can be used to lift the finished part horizontally, while restricting the guide tube 300 to remain in a rotating state and lifting the whole horizontally.

[0065] In this embodiment, the pressing structure includes a pressing plate 700 that moves up and down. The pressing plate 700 has a pressing surface arranged downwards, and the pressing surface is recessed upwards to form a recessed groove with an opening at the bottom. An upper guide groove 706 is formed at the top of the recessed groove and is arranged in a spiral manner along the spiral direction of the spiral groove 101.

[0066] The recessed groove is filled with an elastic layer 702, and the bottom of the elastic layer 702 extends out to form a bottom opening, forming a pressing part 707. A hollowed-out deformation interval 701 is formed between the top of the elastic layer 702 and the top of the recessed groove. The elastic layer 702 has a spirally arranged lower guide groove 705, and the upper guide groove 706 is vertically aligned and connected with the lower guide groove 705.

[0067] The pressure plate 700 is connected to a telescopic shaft 704. The upper end of the telescopic shaft 704 moves through the lower guide groove 705 and the upper guide groove 706 respectively, and is movably connected to the upper guide groove 706. The lower end of the telescopic shaft 704 extends to the bottom of the elastic layer 702 and is connected to a horizontally rotating rotating head 703.

[0068] In step 2), as the rotating disk 200 rotates, the rotating head 703 presses against the two conduits 300 from top to bottom, and the rotating head 703 rotates synchronously with the rotating disk 200 to embed the two conduits 300 into the two rotating grooves 101, and the pressing part 707 presses against the top of the rotating disk 200 downwards to prevent the conduits 300 from coming out of the rotating grooves 101.

[0069] During the rotation of the rotating disc 200, the rotating head 703 presses against the conduit 300, which allows the conduit 300 to be better embedded in the rotating groove 101. The rotating head 703 rotates synchronously with the rotating disc 200 and rotates in a disc-like manner, which can help to embed the conduit 300 into the rotating groove 101.

[0070] Furthermore, the pressing portion 707 of the elastic layer 702 can prevent the conduit 300 embedded in the spiral groove 101 from dislodging from the spiral groove 101. By providing the telescopic shaft 704, the telescopic shaft 704 can move elastically according to the change of the pressure, and in conjunction with the elastic movement of the elastic layer 702, the conduit 300 can be better embedded in the spiral groove 101.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
