Description

Technical Field

[0001] This invention relates to the field of inverter processing technology, and more specifically to a welding device for inverter production and processing. Background Technology

[0002] During the manufacturing process of inverters, welding equipment is required to assist in the assembly of the inverters. The inverters need to be fixed during welding. Existing inverter fixing components have certain limitations, and the position of the inverters needs to be manually adjusted during welding, which affects the speed of inverter manufacturing and welding.

[0003] To address the aforementioned issues, a welding device for inverter processing has emerged on the market. This device includes a welding table with a turntable rotatably connected inside. The turntable contains a clamping assembly, which includes a first bidirectional threaded rod rotatably connected inside the turntable. Moving blocks are threaded onto the outer surfaces of both ends of the first bidirectional threaded rod. Multiple elastic telescopic rods are fixedly connected to the sides of the two moving blocks that are close to each other. This device uses the movement of the moving blocks on both sides of the turntable to move the clamping blocks on one side simultaneously, thus clamping the inverter components on both sides and achieving limited fixation of the inverter components, thereby improving the stability during inverter welding.

[0004] The above-mentioned device has the following problems in actual use: When welding inverter components, the worker needs to hold the welding gun to weld the inverter. During the hand-held process, the welding gun is prone to shaking. The shaking will cause the welding gun to move at different speeds, resulting in uneven melting and solidification time of the solder. This will lead to uneven solder joint size, spikes, bridging or cold solder joints, which will affect the appearance quality. In severe cases, it may also cause the weld to deviate from the center of the bevel, resulting in incomplete penetration or fusion. Summary of the Invention

[0005] This invention provides a welding device for inverter manufacturing and processing, which solves the problem of poor stability of the welding torch during the welding process in existing welding devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for inverter manufacturing and processing, comprising a welding base, positioning mechanisms symmetrically arranged on both sides of the welding base along the width direction of the welding base, and a welding frame with a bottom opening and a welding mechanism; the welding frame is fixedly connected to the welding base; the welding mechanism includes a guide block, a slider, a welding box, a bottom hole on the welding box, guide and stabilizer components symmetrically arranged on both sides of the bottom hole, a welding piece disposed on the guide block, a drive component for driving the guide block to reciprocate along the length direction of the welding frame, and a power component for driving the slider to reciprocate along the length direction of the bottom hole; the guide block is slidably connected to the inner wall of the welding frame; the welding box is fixedly connected to the guide block; the slider is slidably connected to the bottom hole; the guide and stabilizer components include a side block, a side block, a wall block, a rotating shaft, a guide wheel, a bottom groove on the welding box, and a sand pattern disposed on the side block; the side block is connected to the bottom groove, and the sand pattern is in contact with the slider; the side block is fixedly connected to the slider; the wall block is connected to the side block; the rotating shaft is rotatably connected to the wall block; the guide wheel is fixedly connected to the rotating shaft, and the guide wheel is in contact with the inner wall of the welding box.

[0007] The principles and advantages of this scheme are: The inverter components to be welded are placed on the welding base and then positioned by a positioning mechanism. After the inverter components are positioned, the drive assembly moves the welding piece to the predetermined welding position, and then the power assembly moves the welding piece to perform the welding operation on the inverter components. Through this process, the mobility of the welding piece is improved, thereby enabling efficient and stable welding of the inverter components, thus enhancing the welding effect.

[0008] 2. During the sliding of the slider within the bottom hole, the textured surface on the side block comes into contact with the slider surface, forming a microstructured contact surface. This microstructured contact surface first increases the surface roughness, enhancing the static friction and sliding friction damping between the side block and the slider, preventing lateral slippage of the slider during rapid starts, stops, or reversals; secondly... The textured surface disperses local stress, avoids wear concentration caused by point contact, and extends service life. Furthermore, in continuous reciprocating motion, this design can suppress resonance and micro-oscillation, improve motion stability, and ensure accurate welding torch path.

[0009] 3. The core function of the guide wheels contacting the inner wall of the welding box is to bear the lateral load during the movement of the slider, preventing deflection or jamming caused by uneven force on the welding torch. The rolling contact significantly reduces motion resistance, making it more energy-efficient and faster-responding than a pure sliding structure, suitable for continuous reciprocating motion scenarios. Furthermore, the symmetrical arrangement on both sides forms a double-sided limiting constraint, ensuring that the slider moves only along the predetermined lateral axis, eliminating yaw.

[0010] Furthermore, the guide and stabilizing assembly also includes an auxiliary part; the auxiliary part includes a pressure block, a movable block, a chamber opened in the side block, a movable hole opened in the chamber, a moving part for driving the pressure block to reciprocate along the length direction of the side block, and a driving part for driving the movable block to reciprocate along the length direction of the side block; the pressure block is slidably connected to the bottom groove and fixedly connected to the side block; the movable block is slidably connected to the movable hole; the wall block is slidably connected to the chamber and fixedly connected to the movable block; the guide wheel is a rubber wheel; the side block is an elastic block; the movement direction of the movable block is opposite to the movement direction of the pressure block, and the movable block and the pressure block move alternately.

[0011] The reciprocating motion of the pressure block causes the edge block to dynamically fit the textured surface with the slider, thus enabling the textured surface to accommodate minor bumps or contaminants on the slider surface, maintain stable friction, and prevent localized detachment.

[0012] The drive unit continuously presses the rubber wheel against the inner wall of the welding box, thereby establishing a reliable positioning reference between the rubber wheel and the inner wall of the welding box. This improves trajectory repeatability and reduces the probability of slippage. Simultaneously, the rubber material itself possesses internal friction capacity, which further attenuates lateral vibrations and enhances the dynamic stability of the system.

[0013] Furthermore, the alternating movement and continuous pressure of the moving block and the pressing block create a "quasi-continuous support" structure. Therefore, under the action of this "quasi-continuous support" structure, at least one set of components remains effectively constrained during the slider's movement, eliminating the "blind spot" of guide interruption. Simultaneously, the elastic elements alternately deform and recover under pressure, forming a "wave-like" support force distribution, simulating a nearly stepless adjustable guiding effect.

[0014] Furthermore, the stabilizing component also includes a stabilizing part; the stabilizing part includes a moving block, a fixed block, a stabilizing block, and a drive unit for driving the moving block to reciprocate along the length direction of the side block; the moving block is slidably connected to the side block; the fixed block is fixedly connected to the moving block; the stabilizing block is fixedly connected to the fixed block and is in contact with the rotating shaft; the movement direction of the stabilizing block is the same as the movement direction of the moving block.

[0015] When the guide wheel is not compressed and deformed, the stabilizing block acts as an auxiliary support structure to stabilize the rotating shaft under normal conditions. When the guide wheel is compressed and deformed, the stabilizing block disengages from the rotating shaft, allowing the guide wheel to fit more freely against the inner wall of the welded box, thus achieving a switch from "rigid limiting" to "flexible compliance" and avoiding mechanical interference.

[0016] Furthermore, the stabilizing unit also includes a linkage unit; the linkage unit includes a guide plate, a stabilizing guide component, and a stabilizing guide groove opened on the welding box; the guide plate is fixedly connected to the fixing block; the stabilizing guide component is connected to the guide plate; the stabilizing guide groove is located on the movement trajectory of the stabilizing guide component.

[0017] When the guide wheel is not under pressure, the stabilizing block is in contact with the rotating shaft, and the stabilizing component is disengaged from the stabilizing groove. At this time, the slider system is in a "low constraint" state, which facilitates the dynamic adjustment of the side blocks. Once the guide wheel begins to press against the inner wall of the welding box, the stabilizing block disengages from the rotating shaft and drives the stabilizing component to slide into the stabilizing groove to complete the locking. This is equivalent to applying a mechanical preload to the entire slider structure and improving the overall structural rigidity. After the stabilizing component is embedded in the stabilizing groove, it will form a closed frame, which effectively suppresses the micro-deformation of the slider during acceleration.

[0018] Furthermore, the stabilizing unit also includes an auxiliary unit; the auxiliary unit includes a guide rod, a nut seat, a telescopic rod, a guide hole on the guide plate, and a driving component for driving the nut seat to perform vertical reciprocating motion; the guide rod is fixedly connected to the side block; the nut seat is slidably connected to the guide rod; the telescopic rod is fixedly connected to the nut seat; the stabilizing component includes a stabilizing block and a rubber block; the stabilizing block is fixedly connected to the guide plate; the rubber block is slidably connected to the guide hole; the free end of the telescopic rod passes through the guide hole and is fixedly connected to the rubber block.

[0019] After the guide block slides into the guide groove, it can provide an additional guiding reference surface, forming a "dual-track" constraint with the main guide wheel, which significantly reduces the yaw tendency of the slider under lateral acceleration.

[0020] As the guide block slides in completely, the rubber block on it is pressed against the inner wall of the groove, thereby generating controllable static friction to suppress the "creeping" or "jittering" phenomenon of the slider at the moment of start-up and stop. Furthermore, the internal friction characteristics of the rubber material can actively attenuate high-frequency vibrations transmitted by the structure. At the same time, the compressed rubber block also has micro-compensation capabilities, adapting to minor tolerances in the groove dimensions or changes in thermal expansion and contraction.

[0021] Therefore, under the combined effect of the rubber guide wheel leading the direction and absorbing vibration, the guide block assisting the direction and preventing deviation, and the rubber block increasing resistance and reducing vibration, a three-in-one synergistic effect is formed, which provides motion guarantee of "stability upon compression, locking upon positioning, and balance upon movement".

[0022] Furthermore, the guide and stabilization assembly also includes an auxiliary drive unit; the auxiliary drive unit includes a drive shaft, a drive wheel, and a power unit for driving the drive shaft to rotate; the drive shaft is rotatably connected to the side block; the drive wheel is fixedly connected to the drive shaft, and the drive wheel is in contact with the bottom groove.

[0023] During the reciprocating motion of the slider driven by the power component, the drive wheel provides additional power during the pushing phase, shortening the time to reach the target speed. Simultaneously, when the slider needs to reverse at the end of its stroke, the drive wheel can pre-rotate in the opposite direction before the power component, reducing mechanical collisions and vibration transmission, and protecting precision components such as welded parts. Furthermore, when unstable air pressure leads to insufficient output, the drive wheel can automatically supplement power to maintain consistent motion.

[0024] Furthermore, the moving part includes a moving block, a push block, a first spring, a moving hole on the side block, and a moving component for driving the moving block to reciprocate along the length direction of the moving hole; the moving block is slidably connected to the moving hole; the push block is fixedly connected to the moving block; the pressure block is located on the moving trajectory of the push block; and the two ends of the first spring are respectively connected to the pressure block and the bottom groove.

[0025] During the reciprocating motion of the moving block driven by the moving component, the pushing block moves synchronously; during the movement of the pushing block, the pressing block can reciprocate along the length direction of the side block under the combined action of the pushing block and the first spring.

[0026] Furthermore, a cam is fixedly connected to the drive shaft; the cam abuts against the movable block; the drive unit is a second spring; the two ends of the second spring are respectively connected to the movable block and the chamber.

[0027] During cam rotation, when the cam's protrusion abuts against the movable block, the movable block moves closer to the inner wall of the welding box, compressing the second spring. When the cam's protrusion no longer abuts against the movable block, the movable block returns to its original position under the action of the second spring, moving away from the inner wall of the welding box. Therefore, the movable block can reciprocate along the length of the side block.

[0028] Furthermore, the moving part is a third spring; the two ends of the third spring are connected to the moving block and the moving hole respectively; the cam abuts against the push block.

[0029] During cam rotation, when the cam's protrusion abuts against the push block, the moving block moves closer to the slider, compressing the third spring. When the cam's protrusion no longer abuts against the push block, the moving block resets under the action of the third spring and moves away from the slider. Therefore, the moving block can reciprocate along the length of the side block.

[0030] Furthermore, the driving unit is a connecting block; the two ends of the connecting block are fixedly connected to the moving block and the movable block, respectively.

[0031] During the movement of the moving block, the moving block drives the moving block to move synchronously through the connecting blocks. Attached Figure Description

[0048] The moving part is the third spring; the two ends of the third spring are connected to the moving block 28 and the moving hole respectively; the cam 30 abuts against the push block 29.

[0049] The driving unit is a connecting block 31; the two ends of the connecting block 31 are fixedly connected to the moving block 28 and the moving block 19, respectively.

[0050] The driving components include a screw 32 and a gear 33; the screw 32 is rotatably connected to the side block 7; the nut seat 24 is threadedly connected to the screw 32; the gear 33 is fixedly connected to the screw 32; the connecting block 31 is a rack; the rack meshes with the gear 33.

[0051] The drive unit includes a motor housing 34 and a servo motor; the motor housing 34 is fixedly connected to the side block 7; the servo motor is fixedly connected to the inner wall of the motor housing 34; the drive shaft 26 is rotatably connected to the motor housing 34; and the output shaft of the servo motor is fixedly connected to the drive shaft 26.

[0052] Specific implementation process: The inverter component to be welded is placed on the welding base 1, and then the output shaft of the third cylinder 15 pushes the positioning block 16, thereby positioning the inverter component. After the inverter component is positioned, the first cylinder 11 pushes the welding box 5 to reciprocate along the length of the welding frame 2, and the second cylinder 12 drives the slider 4 to reciprocate along the width of the welding frame 2 via the power block 13, thereby enabling the argon arc welding torch 14 to perform welding operations on the inverter component at the required welding position. Therefore, through the above process, the stability of the argon arc welding torch 14 during movement is improved, thereby enabling the argon arc welding torch 14 to perform efficient and stable welding of the inverter component, that is, improving the welding quality.

[0053] During the sliding of slider 4 within the bottom hole, the textured surface of the edge block 6 comes into contact with the surface of slider 4, creating a microstructured contact surface. This microstructured contact surface firstly increases the surface roughness, enhancing the static friction and sliding friction damping between the edge block 6 and slider 4, preventing lateral slippage of slider 4 during rapid starts, stops, or reversals. Secondly, the textured structure disperses localized stress, preventing wear concentration caused by point contact and extending service life. Furthermore, in continuous reciprocating motion, this design suppresses resonance and micro-amplitude oscillations, improving motion stability and ensuring precise welding torch path.

[0054] During the movement of slider 4, it contacts the inner wall of welding box 5 via guide wheel 10. Its core function is to bear the lateral load during slider 4's movement, preventing deflection or jamming caused by uneven force on the welding torch. The rolling contact significantly reduces motion resistance, making it more energy-efficient and faster-responding than a pure sliding structure, suitable for continuous reciprocating motion scenarios. Furthermore, the symmetrical arrangement on both sides forms a double-sided limiting constraint, ensuring that slider 4 moves only along the predetermined transverse axis, eliminating yaw.

[0055] During the synchronous movement of side block 7 and slider 4, the output shaft of the servo motor drives the rotating shaft 9 to rotate. During the rotation of shaft 9, cam 30 rotates synchronously. When the protrusion of cam 30 abuts against push block 29, moving block 28 moves closer to slider 4, compressing the third spring; when the protrusion of cam 30 no longer abuts against push block 29, moving block 28 resets under the action of the third spring and moves away from slider 4. Therefore, moving block 28 can reciprocate along the length of side block 7.

[0056] Therefore, the pressure block 17 can reciprocate along the length of the side block 7 under the combined action of the push block 29 and the first spring 35. Through the reciprocating motion of the pressure block 17, the side block 6 can drive the sand pattern to dynamically fit with the slider 4, so that the sand pattern can accommodate the small bumps or contaminants on the surface of the slider 4, maintain stable friction, and prevent local contact loss.

[0057] During the rotation of cam 30, when the protrusion of cam 30 abuts against movable block 18, movable block 18 moves towards a position closer to the inner wall of welding box 5, and the second spring is compressed; when the protrusion of cam 30 no longer abuts against movable block 18, movable block 18 returns to its original position under the action of the second spring, and movable block 18 moves away from the inner wall of welding box 5. Therefore, movable block 18 can reciprocate along the length direction of side block 7.

[0058] During the movement of movable block 18, the rubber wheel moves synchronously. Therefore, by continuously pressing the inner wall of welding box 5 with the rubber wheel, a reliable positioning reference is formed between the rubber wheel and the inner wall of welding box 5, improving trajectory repeatability and reducing the probability of slippage. At the same time, the rubber material itself has internal friction capacity, which can further attenuate lateral vibration and improve the dynamic stability of the system.

[0059] Furthermore, under the action of cam 30, the movable block 18 and the pressure block 17 alternately move and continuously apply pressure, forming a "quasi-continuous support" structure. Therefore, under the action of the "quasi-continuous support" structure, at least one set of components is always in an effective constrained state during the movement of slider 4, eliminating the "blind zone" of guide interruption. At the same time, the elastic element alternately deforms and recovers under pressure, forming a "wave-like" support force distribution, simulating a guide effect of approximately stepless adjustment.

[0060] During the movement of the moving block 28, the moving block 28 drives the stabilizing block 21 to move synchronously through the rack. When the guide wheel 10 is not compressed and deformed, the stabilizing block 21 acts as an auxiliary support structure to stabilize the rotating shaft 9 under normal conditions; when the guide wheel 10 is compressed and deformed, the stabilizing block 21 disengages from the rotating shaft 9, thereby allowing the guide wheel 10 to fit against the inner wall of the welded box 5 in a freer posture, realizing the switch from "rigid limiting" to "flexible compliance" and avoiding mechanical interference.

[0061] When the guide wheel 10 is not under pressure, the stabilizing block 21 is in contact with the rotating shaft 9, and the guide block 36 and rubber block 37 are disengaged from the guide groove. At this time, the slider 4 system is in a "low constraint" state, which facilitates the dynamic adjustment of the side block 6. Once the guide wheel 10 begins to press against the inner wall of the welding box 5, the stabilizing block 21 disengages from the rotating shaft 9 and drives the guide block 36 and rubber block 37 to slide into the guide groove to complete the locking. This is equivalent to applying a mechanical preload to the entire slider 4 structure and improving the overall structural rigidity. At the same time, the guide block 36 and rubber block 37 will form a closed frame after being embedded in the guide groove, which effectively suppresses the micro-deformation of the slider 4 during acceleration.

[0062] After the guide block 36 slides into the guide groove, it can provide an additional guiding reference surface, forming a "dual-track" constraint with the main guide wheel 10, which significantly reduces the yaw tendency of the slider 4 under lateral acceleration.

[0063] As the guide block 36 slides into the guide groove, the meshing of the rack and pinion 33 causes the screw 32 to rotate, which in turn causes the nut seat 24 to compress and deform the rubber block 37 via the telescopic rod 25, thus pressing the rubber block 37 tightly against the inner wall of the groove. This deformation of the rubber block 37 generates controllable static friction, suppressing the "creeping" or "jittering" phenomenon of the slider 4 during start-up and stop. Furthermore, the internal friction characteristics of the rubber material can actively attenuate high-frequency vibrations transmitted by the structure. Simultaneously, the compressed rubber block 37 also possesses micro-compensation capabilities, adapting to minute tolerances in the groove dimensions or changes in thermal expansion and contraction.

[0064] Therefore, under the combined action of the rubber guide wheel 10 for main direction and vibration absorption, the guide block 36 for auxiliary guidance and anti-deviation, and the rubber block 37 for resistance increase and shock reduction, a three-in-one synergistic effect is formed, which provides motion guarantee of "stability upon compression, locking upon positioning, and balance upon movement".

[0065] During the rotation of drive shaft 26, drive wheel 27 rotates synchronously. The drive wheel 27 provides additional power during the movement of slider 4 driven by second cylinder 12, shortening the time to reach the target speed. Simultaneously, when slider 4 needs to reverse direction at the end of its stroke, drive wheel 27 can pre-rotate in the opposite direction before second cylinder 12, reducing mechanical collisions and vibration transmission, protecting precision components such as argon arc welding torch 14. Furthermore, when unstable gas pressure leads to insufficient output, drive wheel 27 can automatically supplement power to maintain consistent movement.

[0066] In summary, through the coordinated design of a series of structures such as edge block 6, guide wheel 10, stabilizing block 21, and rubber block 37, a slider 4 system integrating high rigidity, self-adaptation, and active drive was constructed, realizing a comprehensive upgrade from "passive guidance" to "active and precise control", ensuring that the argon arc welding gun 14 can achieve high-speed, high-stability, and high-precision continuous operation during the welding of inverter components.
