Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an automated electric welding machine with a rotary electrode clamping mechanism. Background Technology

[0002] In industrial production and everyday equipment manufacturing, T-shaped columnar electrodes or electrode pins are widely used as key conductive connectors in scenarios such as the manufacture of cathode tubes in electrostatic precipitators, the connection of battery tabs to copper wires, and the welding of motor windings to electrode terminals. Their welding quality directly affects the conductivity, structural stability, and service life of the equipment. For example, in electrostatic precipitators, the welding quality of the T-shaped columnar electrode pins to the cathode tube determines the dust removal efficiency; in lithium battery manufacturing, reliable welding of electrodes to copper wires is a core element in ensuring the battery's charging and discharging performance and safety.

[0003] Currently, traditional welding operations between electrode nails and copper wires rely heavily on manual labor. Operators need to manually place the electrode nails and copper wires, and adjust the welding position and angle. This is not only labor-intensive but also inefficient. Especially for welding T-shaped cylindrical electrodes or electrode nails, due to their special shape, traditional feeding methods cannot guarantee the consistency of their feeding state, often resulting in electrode misalignment and positional deviations. This leads to inaccurate welding positions, affecting the performance of subsequent equipment. At the same time, welding quality is greatly affected by the operator's skill level and working condition, easily resulting in problems such as weak welds, incomplete welds, and missed welds, leading to a lower product qualification rate and increased production costs. To address this, we propose an automated welding machine with a rotary electrode clamping mechanism. Summary of the Invention

One end of the second electrode sliding track is fixedly embedded on the upper side of the welding table, and the other end of the second electrode sliding track extends to the bottom of the first electrode sliding track, forming an extension section.

[0010] Preferably, two symmetrically arranged anti-fall limiting rails are fixedly connected to the lower ends of the inner walls on both sides of the electrode sliding rail one and electrode sliding rail two.

An object pushing block is fixedly connected to the push rod port of the first electric push rod. The object pushing block is movably engaged in the extension section of electrode sliding rail two. The object pushing block is inverted "convex" shape.

[0011] Preferably, the electrode rotation clamping mechanism includes an electrode conveying disk, a rotating spindle, a rotating limiting cover, a rotating drive motor, and a rotating actuating component. The electrode conveying disk is movably embedded at the end of the upper side of the welding table away from the welding machine mounting housing.

The rotating limiting cover is fixedly connected to the side of the rotating spindle. The rotating drive motor is fixedly connected to one end of the bottom inner wall of the storage box.

[0012] Preferably, the rotating limiting cover is a hemispherical cover with a hollow inner cavity.

[0013] Preferably, the electrode delivery disk has four electrodes arranged in a ring at equal intervals on its side, and the diameter of the electrodes is matched to that of the electrodes.

[0014] Compared with the prior art, the present invention provides an automated welding machine with a rotary electrode clamping mechanism, which has the following advantages: This automated welding machine with a rotary electrode clamping mechanism achieves fully automatic and precise feeding and posture correction of T-shaped cylindrical electrodes through the coordinated operation of an automatic feeding device and an electrode adjustment device. Electrodes in the storage bin are conveyed in an orderly manner through the discharge holes of the material selection plate. The electrode state adjustment block and the funnel-shaped cavity work together to ensure that the electrodes enter the track in a uniform posture. This solves the problems of inconsistent feeding status, directional skew, and positional deviations often encountered in traditional feeding methods. It significantly reduces manual intervention, improves feeding efficiency, and lays the foundation for accurate subsequent welding positions, preventing equipment performance from being affected by electrode posture issues.

[0015] This automated welding machine with a rotary electrode clamping mechanism employs an automatic rotation welding mode. A rotary drive motor rotates the electrode delivery disc, which, in conjunction with the welding torch, completes the welding process. The entire welding process is precisely controlled by a programmable logic controller (PLC), unaffected by the operator's skill level or working condition. This overcomes the drawbacks of manual welding in the prior art, such as large quality fluctuations and the tendency for incomplete or missing welds. Stable rotary welding ensures uniform and strong weld points, significantly improving the consistency and reliability of welding quality.

[0016] This automated welding machine with a rotary electrode clamping mechanism uses the linkage of components such as an electrode sliding track and an object pushing block to precisely push and stably clamp the electrode to the welding station. As the electrode slides along the track, an anti-drop limit track prevents deviation, and the object pushing block ensures the electrode accurately enters the limit hole, achieving precise control of the welding position. Compared to traditional welding where inaccurate positioning affects equipment performance, this device effectively ensures the accuracy of the welding position, guarantees that the connection between the electrode and cable meets design standards, improves the equipment's conductivity and structural stability, and extends its service life.

[0017] The automated welding machine with a rotary electrode clamping mechanism achieves fully automated operation from electrode loading to welding. The automatic loading device continuously supplies electrodes, the electrode adjustment device corrects the electrode's posture, and the rotary clamping mechanism completes the welding. Each step is coordinated by a logic controller, requiring only an operator to place the cables. This changes the previous technology's high-intensity manual operation and low automation level, reducing human intervention, improving overall production speed, and avoiding efficiency decline due to factors such as human fatigue. It significantly improves the efficiency of T-shaped columnar electrode welding in industrial production. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 An automated welding machine with a rotary electrode clamping mechanism includes a welding machine mounting housing 1. The inner cavity of the welding machine mounting housing 1 is divided into an upper cavity and a lower cavity. A stable base 2 is fixedly connected to the bottom of the welding machine mounting housing 1. A supporting inclined plate 4 is fixedly connected to the upper end of the other side of the welding machine mounting housing 1. The inner cavity of the welding machine mounting housing 1 is provided with a power supply module and connecting lines for power supply. The welding machine mounting housing 1 also includes a programmable logic controller and further includes: The storage box 5 is set on the top of the support inclined plate 4. The inner walls on both sides of the storage box 5 are fixedly connected to the end of the welding machine mounting housing 1. The lower end of the partition plate 10 is not attached to the bottom inner wall of the storage box 5 and has a through slot. The inner wall of the storage box 5 away from the welding machine mounting housing 1 is fixedly connected to the partition plate 10. The upper end of the storage box 5 away from the welding machine mounting housing 1 is fixedly connected to the workpiece placement limiting hole 12. An automatic feeding device is provided at the bottom of the inner cavity of the storage box 5. An electrode adjustment device is installed on the upper end of the inner wall of the welding machine mounting housing 1 near the storage box 5. It includes an electrode adjustment auxiliary plate 13, an electrode sliding track 14, an electrode sliding track 15, and a first electric push rod 16. The electrode adjustment auxiliary plate 13 is fixedly connected to the bottom inner wall of the storage box 5 near the end of the welding machine mounting housing 1, and the electrode adjustment auxiliary plate 13 extends into the upper cavity of the welding machine mounting housing 1. The electrode sliding track 14 is located below the electrode adjustment auxiliary plate 13, and the electrode sliding track 15 is located below the electrode sliding track 14. The welding table 3 is fixedly connected to the side of the welding machine mounting housing 1 away from the material storage box 5, and an electrode rotation clamping mechanism is provided in the inner cavity of the welding table 3. A connector 7 is fixedly connected to one side of the storage box 5, and a pneumatic push rod 8 is fixedly connected to the other side of the connector 7. A connecting block is fixed to the lower end of the push rod of the pneumatic push rod 8. A welding gun 9 is fixedly connected to the side of the connecting block away from the pneumatic push rod 8. A matching welding wire is provided on the welding gun 9. The front side of the electric welding machine mounting housing 1 is set as the work station, and a welding command pedal is provided at the bottom.

[0022] Furthermore, a material flow channel is provided at the lower side of the partition plate 10, and a material support plate 11 is inclined. One end of the material support plate 11 is fixedly connected to the inner wall of the bottom side of the material flow channel, and the other end of the material support plate 11 is inclined upward and fixedly connected to the inner wall of the storage box 5. A limiting slide rail 17 is provided on the inner wall of the bottom side of the storage box 5. The limiting slide rail 17 has a trapezoidal cross-section. The material flow channel at the lower side of the partition plate 10 is the channel for conveying electrodes from the storage box 5 to the automatic feeding device. It cooperates with the material outlet sealing part 22 to prevent subsequent electrodes from sliding down during a single feeding, thus avoiding the accumulation of excess material. The material support plate 11 is inclined, and with the help of gravity, it guides the T-shaped columnar electrodes in the storage box 5 to slide towards the material flow channel, ensuring that the electrodes are continuously replenished to the feeding position. The limiting slide rail 17 has a trapezoidal cross section, which forms a matching sliding structure with the material feeding plate 18, restricting the movement trajectory of the material feeding plate 18 and preventing it from deviating or jamming under the drive of the second electric push rod 19, thus ensuring the stability of the automatic feeding process.

[0023] Furthermore, the automatic feeding device includes a material feeding plate 18, a second electric push rod 19, a pushing connector 21, a material outlet sealing component 22, and a discharge through hole 24. The second electric push rod 19 is fixedly connected to the bottom inner wall of the storage box 5 away from the welding machine mounting housing 1. The material feeding plate 18 is movably snapped into the electrode component 20. The pushing connector 21 is fixedly connected to one end of the upper side of the material feeding plate 18. The pushing rod end of the second electric push rod 19 is fixedly connected to the side of the pushing connector 21. A material outlet sealing member 22 is fixedly connected to the other end of the upper side of the material conveying plate 18. The material outlet sealing member 22 is inverted L-shaped, and the free end of the material outlet sealing member 22 is rectangular and matches the material flow channel on the partition plate 10. The material conveying plate 18 has a first discharge through hole 24 on its upper side, corresponding to the lower part of the material outlet sealing member 22. The storage box 5 has a second discharge through hole 24 on its bottom inner wall, away from the second electric push rod 19. The two discharge through holes 24 are identical in shape, both being narrow "I"-shaped through holes. The second electric push rod 19 drives the material conveying plate 18 to slide back and forth along the limiting slide rail 17 via the push connector 21, serving as the power source for automatic feeding. The first discharge through hole 24 on the material conveying plate 18 is narrow "I"-shaped, which is compatible with the lateral structure of the T-shaped columnar electrode and can carry one electrode at a time. When the material conveying plate 18 slides to align with the second discharge through hole 24 on the bottom side of the storage box 5, the electrode can fall through the through hole, achieving precise single-material conveying. The material inlet sealing component 22 is inverted L-shaped. When it slides with the material feeding plate 18, it is embedded in the material flow groove of the welding command pedal 10. After the material is picked up, it blocks the subsequent electrodes to avoid material feeding chaos. The orderly supply of electrodes is achieved through linkage with the second electric push rod 19.

[0024] Furthermore, two symmetrically arranged electrode state adjustment blocks 23 are fixedly connected to the upper side of the material feeding plate 18 away from the pusher connector 21. The opposing surfaces of the two electrode state adjustment blocks 23 are both set as inclined surfaces. When the material feeding plate 18 slides with the electrodes, the inclined surfaces and the inner wall of the storage box 5 form a compression space, which corrects the posture of the T-shaped columnar electrodes in the discharge through hole 24. The horizontal part of the electrode is smoothly engaged in the horizontal groove of the through hole by the inclined surface thrust, and the vertical part hangs down naturally, ensuring that the electrodes enter the subsequent adjustment device in a uniform posture, thus solving the problem of electrode skew in traditional feeding.

[0025] Furthermore, two symmetrically arranged electrode adjustment auxiliary plates 13 are fixedly connected to the upper end of the inner wall of the welding machine mounting housing 1 near the material storage box 5. A limit plate is fixedly connected to the inner wall of the other side of the two electrode adjustment auxiliary plates 13. The upper ends of the opposite surfaces of the two electrode adjustment auxiliary plates 13 are inclined slopes. A funnel-shaped cavity is formed between the two electrode adjustment auxiliary plates 13, the limit plate, and the inner wall of the welding machine mounting housing 1. The upper end of the funnel-shaped cavity is connected to the second discharge through hole 24, and the lower end is an open opening. Electrode sliding track 14 is fixedly connected to the inner wall of the welding machine mounting housing 1 near the material storage box 5, and is inclined. Electrode sliding track 14 is located directly below the funnel-shaped cavity. Electrode sliding track 25 is fixedly connected to one end of the bottom surface of electrode sliding track 14. One end of electrode sliding track 25 is fixedly embedded in the upper side of the welding table 3, and the other end of electrode sliding track 25 extends to the bottom of electrode sliding track 14 as an extension section. The two electrode adjustment auxiliary plates 13, together with the limiting plate and the inner wall of the welding machine mounting housing 1, form a funnel-shaped cavity. Its upper end is connected to the second discharge through hole 24, and its lower end opening is directly opposite electrode sliding track 14. After the electrode falls from the through hole, it slides down the inclined surface of the electrode adjustment auxiliary plate 13. The horizontal part is blocked by the limiting plate, and the vertical part hangs down, forming a uniform posture. The electrode sliding track 14 is inclined and guides the electrode to slide down with the help of gravity; the extension of the electrode sliding track 15 receives the electrode and guides it to the direction of the welding table 3, providing a path for the electrode to enter the rotary clamping mechanism.

[0026] Furthermore, two symmetrically arranged anti-fall limiting rails 25 are fixedly connected to the lower ends of the inner walls on both sides of the electrode sliding rail 14 and the electrode sliding rail 25. A first electric push rod 16 is fixedly connected to one end of the bottom inner wall of the upper cavity of the welding machine mounting housing 1. An object pushing block 26 is fixedly connected to the push rod end of the first electric push rod 16. The object pushing block 26 is movably engaged in the extension section of the electrode sliding rail 25. The object pushing block 26 is inverted "convex" shape. The anti-fall limiting rails 25 are symmetrically arranged at the lower ends of the inner walls on both sides of the electrode sliding rail 14 and the electrode sliding rail 25 to form a lateral limiting of the electrode and prevent the electrode from shifting or falling due to tilting or vibration during the sliding process. The first electric actuator 16 drives the inverted "convex" shaped object pusher block 26 to slide along the extension of the electrode sliding track 2 15. Through the thrust, the electrode end is pushed into the limiting hole 35 of the electrode conveying disk 27, so as to achieve precise docking between the electrode and the welding station and ensure the consistency of the welding position.

[0027] Furthermore, the electrode rotation clamping mechanism includes an electrode conveying disk 27, a rotating spindle 28, a rotating limiting cover 29, a rotating drive motor 30, and a rotating actuating component 31. The electrode conveying disk 27 is movably embedded at the end of the upper side of the welding table 3 away from the welding machine mounting housing 1. The rotating spindle 28 is fixedly connected to the bottom axis of the electrode conveying disk 27. The lower end of the rotating spindle 28 extends into the inner cavity of the storage box 5 and is rotatably connected to the bottom inner wall of the storage box 5. The rotating limiting cover 29 is fixedly connected to the side of the rotating spindle 28. The rotating drive motor 30 is fixedly connected to one end of the bottom inner wall of the storage box 5. The rotating actuating component 31 is fixedly connected to the drive shaft of the rotating drive motor 30. The rotating drive motor 30 is the power source for the electrode rotation and conveying. Its drive shaft drives the rotating actuating component 31 to rotate. The rotating actuating component 31, through cooperation with the rotating limiting cover 29, drives the rotating spindle 28 to rotate, thereby causing the electrode conveying disk 27 to rotate synchronously. The limiting hole 35 on the side of the electrode conveying plate 27 is adapted to the electrode diameter and is used to receive and fix the electrode conveyed from the track. By rotating, the electrodes are sequentially sent to the welding station to realize the preparation for continuous welding of multiple electrodes.

[0028] Furthermore, the rotating limiting cover 29 is a hemispherical cover with a hollow inner cavity. Four first arc-shaped grooves 32 are equidistantly distributed in a ring on the side of the rotating limiting cover 29. A second arc-shaped groove 33 is formed between every two first arc-shaped grooves 32 on the side of the rotating limiting cover 29. A rotating actuating member 31 is fixedly connected to the side of the rotating actuating member 31 closest to the rotating limiting cover 29. A actuating block 34 is fixedly connected to the other side of the rotating actuating member 31, forming an obtuse angle with the rotating actuating member 31. A columnar actuating block, shaped like the second arc-shaped groove, is fixedly connected to the end of the actuating block 34 furthest from the rotating actuating member 31. The shape of the rotating actuating element 31 matches the first arc-shaped groove 32, allowing it to rotate within the first arc-shaped groove 32. The second arc-shaped groove 33 of the rotating limiting cover 29 matches the shape of the columnar toggle block 34. When the rotating actuating element 31 rotates, the toggle block 34 embeds into the second arc-shaped groove 33 and pushes the rotating limiting cover 29 to rotate, thus switching the position of the electrode conveying plate 27. When the electrode reaches the welding station, the main body of the rotating actuating element 31 slides into the first arc-shaped groove 32, using the limiting effect of the arc-shaped groove to keep the rotating limiting cover 29 stable, ensuring the electrode position is fixed during welding. The obtuse angle design of the toggle block 34 reduces mechanical impact during pushing and ensures smooth rotation.

[0029] Furthermore, four equidistant holes 35 are provided on the side of the electrode conveying disk 27. The diameter of the holes 35 is matched with that of the electrode. The limiting holes 35 are also provided on the side of the electrode conveying disk 27 in an annular arrangement. Their diameter is adapted to the longitudinal part of the T-shaped columnar electrode. When the electrode is pushed to this location by the object pushing block 26, the longitudinal part is embedded in the hole, and the transverse part is supported on the surface of the electrode conveying disk 27, thereby achieving axial positioning of the electrode. With the rotation of the electrode conveying disk 27, the positioned electrodes can be sequentially sent to the bottom of the welding torch 9, providing a stable clamping base for automatic rotary welding.

[0030] Working principle: This automated welding machine with a rotary electrode clamping mechanism achieves automatic feeding, posture adjustment, precise welding, and stable quality control of T-shaped cylindrical electrodes through the orderly linkage of its components. The specific working principle is as follows: During the electrode loading stage, the operator places a batch of T-shaped cylindrical electrodes into the storage bin 5. Supported by the inclined material support plate 11, the electrodes slide towards the material flow channel. The programmable logic controller (PLC) initiates the automatic loading program, and the second electric push rod 19 drives the material conveying plate 18 to slide along the limiting slide rail 17 via the connecting piece 21. When the first discharge through-hole 24 on the material conveying plate 18 moves to the bottom of the inner cavity of the storage bin 5, a single electrode falls into the narrow "I"-shaped through-hole. At this time, the material outlet sealing piece 22 moves with the material conveying plate 18 and fits precisely into the material flow channel, preventing subsequent electrodes from falling out. As the material conveying plate 18 continues to slide, the inclined surfaces of the two electrode state adjustment blocks 23 engage with the inner wall of the storage bin 5 to perform preliminary posture correction on the electrodes within the through-holes, ensuring that the lateral portion of the T-shaped electrodes is stably engaged within the through-holes. When the first discharge through hole 24 is aligned with the second discharge through hole 24 on the bottom side of the storage box 5, the electrode falls into the electrode adjustment device through the through hole, completing the automatic feeding action and realizing the continuous and orderly supply of T-shaped electrodes. During the electrode adjustment stage, the falling electrode first enters the funnel-shaped cavity formed by the two electrode adjustment auxiliary plates 13, the limiting plate, and the inner wall of the housing 1. Since the upper end of the cavity is connected to the second discharge through hole 24, and the upper part of the opposite surface of the electrode adjustment auxiliary plate 13 is an inclined slope, the electrode slides down the slope under the action of gravity. The horizontal part is blocked by the limiting plate, and the vertical part hangs down naturally, forming a uniform posture. Then the electrode enters the inclined electrode sliding track 14, and the anti-fall limiting tracks 25 on both sides prevent the electrode from deviating or falling. After the electrode slides down the track to the extension of the electrode sliding track 25, the first electric push rod 16 drives the inverted "convex" shaped object pushing block 26 to slide along the track, pushing the electrode towards the welding table 3 until the end of the electrode enters the limiting hole 35 of the electrode conveying plate 27, completing the precise positioning of the electrode and ensuring the consistency of the welding position. During the welding stage, the operator places the cable to be welded in the designated position on the welding table 3 and presses the welding command pedal to trigger the welding program. The programmable logic controller synchronously starts the rotary drive motor 30 and the pneumatic push rod 8. The pneumatic push rod 8 drives the welding torch 9 to move down to the welding station via the connecting block. The drive shaft of the rotary drive motor 30 drives the rotary actuating component 31 to rotate. The actuating block 34 on the rotary actuating component 31 first embeds into the second arc-shaped groove 33 of the rotary limiting cover 29, pushing the hemispherical rotary limiting cover 29 to rotate, and then drives the electrode conveying disk 27 to rotate via the rotary main shaft 28. When the rotation reaches the welding angle, the main body of the rotary actuating component 31 slides into the first arc-shaped groove 32 to ensure that the electrode conveying disk 27 is stable in the current position. At this time, the welding torch 9 begins to weld the connection point between the electrode and the cable. As the electrode rotates automatically with the electrode conveying disk 27, the welding torch 9 completes the welding, forming a uniform and firm weld point. Throughout the process, the power module provides stable power to all electrical components, and the programmable logic controller precisely controls the timing of each component's actions, achieving seamless integration of automatic feeding, posture adjustment, and rotary welding. Through the cooperation of the material feeding plate 18 and the electrode adjustment auxiliary plate 13, the consistent feeding state of the T-shaped electrode is ensured. With the linkage of the rotary drive motor 30 and the rotary limit cover 29, precise control of the welding angle is achieved. The automatic rotary welding mode eliminates the uncertainty of manual operation, requiring only the operator to place the cable to complete the welding, greatly improving welding efficiency and quality stability, and meeting the high standard requirements of T-shaped columnar electrode welding in various application scenarios.
