Description

Technical Field

[0001] This invention belongs to, but is not limited to, the field of welding equipment technology, and particularly relates to an automatic wire feeding system for straight wire magazines. Background Technology

[0002] The wire feeding system is a key component of welding equipment, primarily used to stably and accurately deliver the welding wire, ensuring the continuity and quality of the welding process. The welding wire is generally soft and coiled together before being fed into the welding machine via the system. However, some welding wires are hard and brittle, and are generally short enough to be coiled, requiring manual feeding of each wire individually, which is inefficient. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an automatic yarn feeding system for straight yarn magazines.

[0004] The present invention is implemented as follows: an automatic wire feeding system for straight wire magazine, the system comprising a mounting plate, a clamping and feeding mechanism, a wire magazine, a servo motor, a closed wire guiding mechanism, a linear module and a welding wire feeder;

[0005] The linear module is fixed on the mounting plate, and a connecting bracket is provided on the slide of the linear module. The clamping and feeding mechanism and the servo motor are both located on the connecting bracket. The servo motor is connected to the wire magazine, and the welding wire feeder is located on the other side of the wire magazine opposite to the servo motor.

[0006] The closed wire guide mechanism includes a wire magazine sealing plate, a mini electric push rod, and a sealing block; a gap is formed between the wire magazine sealing plate and the lower end of the wire magazine, and the wire magazine sealing plate is provided with a notch for pushing out the welding wire; the mini electric push rod is located below the wire magazine sealing plate, and the end of the push rod is connected to the sealing block;

[0007] The sealing block enters or leaves the wire magazine sealing plate notch under the drive of a mini electric push rod, and is used to selectively close the wire magazine outlet; the sealing block is provided with an interference groove corresponding to the inlet of the welding wire feeder, so that the inlet of the welding wire feeder does not interfere with the sealing block when the sealing plate notch is closed;

[0008] The clamping and feeding mechanism is used to push the welding wire into the welding wire feeder.

[0009] Furthermore, the notch of the wire feeder sealing plate is aligned with the wire tube outlet of the wire feeder, so that each welding wire can be moved to the notch position sequentially after the wire feeder rotates.

[0010] Furthermore, the push rod end of the mini electric push rod is fixed to the wire mesh sealing plate through a pressure plate, so that when the push rod extends or retracts, it drives the sealing block to open and close the notch of the wire mesh sealing plate.

[0011] Furthermore, the slide of the linear module moves up and down to adjust the installation height of the servo motor and the wire magazine, so as to accommodate the replacement of wire magazines of different lengths.

[0012] Furthermore, the width of the connecting block is smaller than the notch width of the silk storage sealing plate, so that the sealing block can completely close the silk exit path when it is inserted into the notch.

[0013] Furthermore, the wire feeder is fixed to the mounting plate via a connecting plate, and its inlet is engaged with the interference groove on the sealing block.

[0014] Furthermore, the clamping and feeding mechanism performs clamping, pushing, and releasing actions on the welding wire, pushing the welding wire to the inlet of the welding wire feeder.

[0015] Furthermore, the servo motor is connected to the wire magazine via a coupling.

[0016] Furthermore, the working principle of the aforementioned automatic straight yarn feeder system is as follows:

[0017] The welding wire is manually placed into the wire spool. After starting, the motor rotates at a certain angle and then stops. Under the action of the telescopic cylinder 2, the clamping and feeding mechanism moves the clamping cylinder forward to the wire clamping position, clamping the welding wire. Under the action of the telescopic cylinder 1, the welding wire moves downward. After moving a certain distance, it is released and returns to the starting state. At the same time as the welding wire is clamped, the mini electric push rod retracts, and the wire magazine sealing plate notch opens to facilitate the welding wire to extend into the inlet of the welding wire feeder. At this time, the welding wire feeder also starts working, feeding the incoming welding wire from the outlet into the inlet of the welding wire feeder.

[0018] The wire feeding time can be set according to the running speed of the wire feeder and the length of the wire. After the time is up, the wire magazine sealing plate notch closes until the next wire is fed in. Alternatively, a sensor can be installed at the outlet of the wire magazine to detect whether there is wire.

[0019] The feeding process for each welding wire is the same, and the welding wire is changed by rotating the motor.

[0020] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this invention are as follows:

[0021] The automatic wire feeding system for straight wires provided by this invention can store multiple welding wires at once and feed them automatically, which not only improves efficiency but also adapts to straight welding wires of different lengths. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] like Figures 1-5 As shown, this embodiment of the invention provides an automatic wire feeding system for a straight wire magazine. The system includes: a clamping and feeding mechanism 1, a servo motor 2, a linear module 3, a connecting bracket 4, a coupling 5, a mounting plate 6, a mini electric push rod 7, a connecting plate 8, a pressure plate 9, a welding wire feeder 10, a wire magazine sealing plate 11, a wire magazine 12, and welding wire 13.

[0032] The servo motor 2 is connected to the wire magazine 12 via a coupling 5. The clamping and feeding mechanism 1 is connected to the connecting bracket 4 via a welding plate. One end of the connecting bracket 4 is connected to the linear module 3, and the other end is fixed to the servo motor 2.

[0033] The lower end of the silk cartridge sealing plate 11 and the silk cartridge 12 have a certain gap to facilitate the motor to rotate the silk cartridge by a certain angle. The notch of the silk cartridge sealing plate 11 corresponds to the silk spool outlet of the silk cartridge 12. The end of the silk cartridge sealing plate 11 is fixed to the mounting plate 6. Below the silk cartridge sealing plate 11 is a mini electric push rod 7, which can extend and retract a certain distance. The end of the electric push rod 7 has a sealing block 14, which is used to close the notch of the silk cartridge sealing plate. The mini electric push rod 7 is fixed to the silk cartridge sealing plate 11 by a pressure plate 9.

[0034] The wire feeder 10 is fixed to the mounting plate 6 by the connecting plate 8, and the inlet of the wire feeder is embedded in the interference groove 23 in the mini electric push rod sealing block 14.

[0035] The linear module 3 is fixed on the mounting plate 6, and its slide can move up and down. If a longer welding wire needs to be replaced, the wire magazine can be removed and replaced, and the slide can be moved up.

[0036] The automatic straight wire feeder system is mounted on the mounting plate 6, forming an integrated straight wire feeding platform. The linear module 3 is vertically fixed to the side of the mounting plate 6, and its slide moves vertically up and down, providing height adjustment for the system. The servo motor 2 is located at the top of the system and is suspended by a connecting bracket 4. The connecting bracket 4 is also fixed to the slide of the linear module 3, allowing the servo motor 2 to rise and fall synchronously with the slide. The wire magazine 12 is vertically arranged at the output end of the servo motor 2. The wire magazine sealing plate 11 is located at the lower end of the wire magazine 12 and is fixed to the mounting plate 6. A certain gap is maintained between the wire magazine sealing plate 11 and the wire magazine 12 to allow for angular rotation of the wire magazine 12. The welding wire feeder 10 is located in front of and below the wire magazine sealing plate 11 and is fixed to the mounting plate 6 via a connecting plate 8, maintaining a stable spatial correspondence with the entire wire feeding mechanism.

[0037] The servo motor 2 is precisely coaxially connected to the wire magazine 12 via the coupling 5, enabling lossless transmission of motor torque to the wire magazine 12 and achieving step-by-step rotation of the wire magazine. The clamping and feeding mechanism 1 is fixed to the side of the connecting bracket 4 via the connecting plate 8, with its outlet facing the inlet of the wire feeder 10, ensuring that the welding wire can stably enter the wire feeder after being taken out of the wire magazine 12. The wire magazine sealing plate 11 is fixed to the push rod end of the mini electric push rod 7 via the pressure plate 9, forming a closed mechanism; the mini electric push rod 7 is installed below the wire magazine sealing plate 11, and its pushing action causes the sealing block 14 to open and close the notch on the wire magazine sealing plate 11. The wire feeder 10 is assembled with the mounting plate 6 via the connecting plate 8, and its inlet position is precisely engaged with the interference groove 23 on the sealing block 14.

[0038] During the wire feeding action, the servo motor 2 drives the wire magazine 12 to rotate around the central axis, causing the straight welding wire 13 in the wire magazine 12 to move segment by segment to the notch position of the wire magazine sealing plate 11. Due to the gap between the wire magazine sealing plate 11 and the wire magazine 12, the wire magazine 12 can keep the wire spool outlet aligned with the notch during rotation. The mini electric push rod 7 pushes the sealing block 14 into the notch of the wire magazine sealing plate 11 in the closed state. The interference groove 23 of the sealing block 14 fits into the inlet of the welding wire feeder 10, thus forming a completely closed welding wire guide path. The clamping and feeding mechanism 1 clamps the welding wire 13 and pushes it into the inlet of the welding wire feeder 10.

[0039] During operation, the servo motor 2 intermittently rotates the wire magazine 12 at a set angle, accurately moving the next welding wire 13 to the notch of the sealing plate. Then, the mini electric push rod 7 extends, and the sealing block 14 closes the notch of the wire magazine sealing plate 11. The clamping and feeding mechanism 1 activates, clamping and pushing the welding wire into the wire feeder 10. The linear module 3, by adjusting the height of the slide, can accommodate welding wires of different lengths. If the wire magazine 12 needs to be replaced, simply release the slide to move it upwards for a quick replacement. The entire system, through the rotation of the wire magazine 12 for wire feeding, the forward and backward movement of the sealing block 14, the advancement of the clamping and feeding mechanism 1, and the continuous feeding from the wire feeder 10, achieves an automated operation process from wire picking and feeding to continuous output of the welding wire.

[0040] like Figures 1-7 As shown, the working principle of the automatic straight yarn feeder system is as follows:

[0041] The welding wire is manually placed into the wire spool. After starting, the motor rotates at a certain angle and then stops. Under the action of the telescopic cylinder 2, the clamping and feeding mechanism moves the clamping cylinder forward to the wire clamping position, clamping the welding wire. Under the action of the telescopic cylinder 1, the welding wire moves downward. After moving a certain distance, it is released and returns to the starting position. At the same time as the welding wire is clamped, the mini electric push rod retracts, and the wire magazine sealing plate notch opens to allow the welding wire to extend into the wire feeder inlet. At this time, the wire feeder also starts working, feeding the incoming welding wire from the outlet into the welding machine's welding wire inlet.

[0042] The wire feeding time can be set according to the operating speed of the wire feeder and the length of the welding wire. After the time is up, the notch of the wire magazine sealing plate closes until the next welding wire is fed in. Alternatively, a sensor can be installed at the outlet of the wire magazine to detect whether there is welding wire.

[0043] The feeding process for each welding wire is the same, and the welding wire is changed by rotating the motor.

[0044] The automatic wire feeding system for straight wire magazines in this embodiment is mounted on the mounting plate 6. The straight module 3 is fixed to the left side of the mounting plate 6, and its slide provides vertical position adjustment capability for the connecting bracket 4. The servo motor 2 is mounted on the upper end of the connecting bracket 4 and coaxially connected to the central axis of the wire magazine 12 via a coupling 5, enabling the servo motor 2 to drive the wire magazine 12 to perform angular positioning. The wire magazine sealing plate 11 is fixed to the lower part of the mounting plate 6, forming a stable gap between its upper end and the lower end of the wire magazine 12, allowing the wire magazine 12 to maintain a stable posture during rotation. The welding wire feeder 10 is fixed to the front of the mounting plate 6 via a connecting plate 8, and its inlet position corresponds to the notch in the wire magazine sealing plate 11. The clamping and feeding mechanism 1 is mounted on the side of the connecting bracket 4, capable of pushing the welding wire 13 from the direction of the wire magazine 12 towards the inlet of the welding wire feeder 10.

[0045] In this embodiment, the servo motor 2 drives the wire magazine 12 to rotate sequentially, causing the straight welding wires 13 to move one by one to the notch area of ​​the wire magazine sealing plate 11. The clamping and feeding mechanism 1 clamps the welding wires 13 with the grippers 18 and pushes them downward, allowing the welding wires to smoothly enter the wire feeder 10. The linear module 3 provides installation space for changing welding wires 12 of different lengths through the lifting and lowering of its slide, making the wire magazine 12 detachable and assembleable during replacement.

[0046] In this embodiment, there is an installation gap between the lower end of the wire magazine sealing plate 11 and the wire magazine 12, and the gap is maintained within a range sufficient to allow the wire magazine 12 to rotate around the center. The notch of the wire magazine sealing plate 11 precisely corresponds to the wire spool outlet of the wire magazine 12, so that after the wire magazine 12 is rotated by the servo motor 2, different welding wires 13 can be aligned with the notch in sequence. A mini electric push rod 7 is installed on the lower side of the wire magazine sealing plate 11, and a sealing block 14 is fixed at the end of its push rod. The sealing block 14 can enter the notch of the wire magazine sealing plate 11 in a horizontal direction.

[0047] Before the welding wire 13 enters the welding wire feeder 10, the mini electric push rod 7 first retracts, removing the sealing block 14 from the notch of the wire magazine sealing plate 11, thus fully opening the notch and allowing the welding wire 13 to be smoothly pushed into the notch through the clamping feeding mechanism 1. After the welding wire 13 enters the welding wire feeder 10, the mini electric push rod 7 extends again, causing the sealing block 14 to enter the notch and close it.

[0048] In this embodiment, the linear module 3 is installed on the right side of the mounting plate 6, and its slide is connected to the connecting bracket 4, so that the servo motor 2 and the wire magazine 12 move together with the slide. When a longer welding wire 13 is required, the slide can be moved upward by controlling the linear module 3 to provide sufficient installation space for the wire magazine 12. After the wire magazine 12 is disassembled, it can be replaced with a wire magazine of the same specification or a different length, achieving quick replacement.

[0049] The height adjustment of the linear module 3 not only facilitates the replacement of the wire magazine 12, but also ensures the angle and positional accuracy of the welding wire 13 entering the welding wire feeder 10. After the slide table is raised and lowered, the spatial relationship between the wire magazine sealing plate 11 and the welding wire feeder 10 remains consistent, so that the welding wire 13 can still accurately enter the welding wire feeder 10 after the wire magazine is replaced.

[0050] In this embodiment, the wire feed sealing plate 11, the wire feed 12, the mini electric push rod 7, and the sealing block 14 constitute a closed wire guiding mechanism. The wire feed sealing plate 11 has a rectangular notch. The wire feed 12 rotates under the drive of the servo motor 2, and its wire spool outlet sequentially reaches the notch position. The mini electric push rod 7 is vertically mounted, and its push rod end is fixed to the sealing block 14 by a pressure plate 9, allowing the sealing block 14 to enter the notch position. The front end of the sealing block 14 is also provided with an interference groove 23 to avoid interference with the inlet of the welding wire feeder 10.

[0051] When it is necessary to prevent the welding wire 13 from passing through, the mini electric push rod 7 extends, causing the sealing block 14 to completely close the notch and block the welding wire path; when it is necessary to feed the wire, the mini electric push rod 7 retracts, causing the notch to fully open. The sealing block 14 is smaller than the notch size, and in the closed state, it can seal the welding wire outlet and prevent the welding wire 13 from falling out during the rotation of the wire magazine.

[0052] This embodiment also provides a wire feeding control method for the above-mentioned automatic wire feeding system for straight wire magazines, specifically including the following steps:

[0053] Step 1: Place the welding wire into the wire spool in the wire magazine;

[0054] Step 2: The servo motor drives the wire magazine to rotate at a set angle, so that the welding wire to be fed is moved to the notch of the wire magazine sealing plate;

[0055] Step 3: The clamping and feeding mechanism performs clamping and pushing actions to push the welding wire downwards to the inlet position of the welding wire feeder;

[0056] Step 4: The mini electric push rod retracts, causing the sealing block to leave the wire magazine sealing plate notch and opening the wire outlet path;

[0057] Step 5: Start the wire feeder to continuously feed the welding wire to the welding machine;

[0058] Step 6: Determine whether the welding wire has been completely fed based on the wire feeding time or the exit sensor signal. After the wire is completely fed, seal the gap with the sealing block and start feeding the next welding wire.

[0059] The rotation angle of the servo motor is used to determine the position of the next welding wire, so that the feeding of each welding wire is completed sequentially by the fixed-angle rotation of the wire magazine.

[0060] This embodiment uses the above-described wire feeding control method to achieve automatic replacement and continuous feeding of welding wire 13. After the operation starts, the servo motor 2 drives the wire magazine 12 to rotate at a preset angle, so that a certain welding wire 13 reaches the notch position of the wire magazine sealing plate 11. The clamping and feeding mechanism 1 clamps the welding wire 13 and pushes it downward, so that the welding wire 13 passes through the notch area of ​​the wire magazine sealing plate 11. The mini electric push rod 7 is in the retracted state at this time, so that the sealing block 14 leaves the notch, and the welding wire 13 smoothly enters the welding wire feeder 10.

[0061] The wire feeder 10 starts immediately after the welding wire 13 enters, continuously feeding the welding wire into the welding machine. The wire feeding time can be determined by a preset time or by a sensor that detects the outlet of the wire magazine 12. When the welding wire 13 is used up, the mini electric push rod 7 extends, the sealing block 14 closes the notch, and then the servo motor 2 rotates the wire magazine 12 again, so that the next welding wire 13 enters the wire feeding process in sequence.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
