Description

Technical Field

[0001] This invention relates to the field of automotive parts welding technology, and more specifically to a welding device for new energy vehicle parts with defect detection capabilities. Background Technology

[0002] In the field of automotive component welding technology, welding devices with defect detection are integrated equipment specifically designed for welding scenarios of new energy vehicle components. Their core feature is the combination of welding functions with real-time defect detection capabilities. Based on traditional welding mechanisms, this device integrates advanced detection components such as visual sensors, infrared thermal imagers, and ultrasonic detectors. During or after welding, it can automatically identify defects in the welded area, such as cracks, porosity, lack of fusion, and weld beads, through image recognition, temperature field analysis, and acoustic feedback technologies. This ensures the welding quality and safety of key components for new energy vehicles while reducing the cost and error of manual inspection.

[0003] For welding processes, there is an existing intelligent welding and 3D camera inspection device with publication number CN115415704A, which includes a housing. The housing contains a conveying mechanism, an inspection mechanism, and a welding mechanism, while a control mechanism is located outside the housing. A partition is fixedly installed in the middle of the housing, with support legs fixedly installed at the four corners of the bottom of the partition, and side frames fixedly installed at the four corners of the top of the partition.

[0004] The aforementioned equipment integrates the detection components with the welding equipment, improving work efficiency. However, it has significant technical shortcomings in practical applications. During component welding, the welding arc intensity is high and its duration is synchronized with the welding process. The detection probe of the existing device is directly exposed to the welding environment without effective protective measures. The strong light generated by welding directly shines on the detection probe, causing accelerated aging of the probe's photosensitive element. This not only shortens the probe's lifespan but also easily causes detection signal distortion, making it difficult to accurately identify welding defects. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a welding device for new energy vehicle parts with defect detection, which can effectively solve the problem that the detection probe is directly exposed to the welding environment and lacks effective protection measures in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a welding device for new energy vehicle parts with defect detection, including a support assembly.

[0008] The opening and closing assembly includes a detection port and a piston groove at the bottom of the mounting bracket. A detection probe is provided in the detection port, and a piston plate is slidably connected in the piston groove. The detection probe is used to detect the welding effect of the parts after welding. An opening and closing plate is provided at the bottom of the detection port. The opening and closing of the opening and closing plate is controlled by the sliding of the piston plate. The opening and closing plate is used to close the detection port during welding.

[0009] The mounting bracket is equipped with a probe focusing assembly, which is used to control the focusing of the detection probe. The probe focusing assembly includes a piston housing fixedly connected to the mounting bracket, a piston rod slidably connected inside the piston housing, and the detection probe is mounted on the bottom of the piston rod.

[0010] Preferably, a longitudinal slide groove is provided above the support component, and the frame is slidably connected in the longitudinal slide groove. A transverse slide groove is provided in the frame, and the mounting bracket is slidably connected in the transverse slide groove.

[0011] Preferably, the linear module includes a motor installed in a mounting bracket, the output end of the motor is fixedly connected to a lead screw, the side wall of the lead screw is provided with a linear slider, and the side wall of the linear slider is fixedly connected to the mounting ring.

[0012] Preferably, the bottom of the lead screw is provided with a lifting groove and a spiral groove, a lifting rod is inserted into the lifting groove, and a spiral slider is slidably connected in the spiral groove, and the spiral slider is fixedly connected to the side wall of the lifting rod.

[0013] Preferably, the bottom of the piston groove is slidably connected to an opening and closing rack, the opening and closing rack is meshed with an opening and closing gear, and the side wall of the opening and closing gear is fixedly connected to the opening and closing plate.

[0014] Preferably, the mounting frame has an oil groove, a sliding plate is slidably connected in the oil groove, the oil groove and the sliding plate are connected by a spring, a sliding rod is fixedly connected to one side of the sliding plate, the sliding rod passes through the mounting frame, and a driving triangular block is abutted at the other end of the mounting frame.

[0015] Preferably, the side wall of the mounting bracket is provided with a fixing component, which includes a fixing groove, an unlocking groove, and an unlocking channel formed within the mounting bracket. The unlocking groove communicates with the fixing groove through the unlocking channel. A fixing block is slidably connected within the fixing groove. The fixing groove and the fixing block are connected by a second spring. The bottom of the fixing block is inserted into a fixing slot. The fixing slot is formed within the side wall of the sliding rod. An unlocking wedge is slidably connected within the unlocking groove by a third spring.

[0016] Preferably, a rotating assembly is provided inside the base plate. The rotating assembly includes a rotating groove formed on the base plate, a fixed shaft is fixedly connected inside the rotating groove, a rotating gear is rotatably connected to the side wall of the fixed shaft via a torsion spring, and a worktable is fixedly connected to the top of the rotating gear.

[0017] Preferably, the side wall of the rotating gear is provided with a transmission rod, the transmission rod is slidably connected in the transmission groove, the transmission groove and the transmission rod are connected by a No. 5 spring, the bottom of the transmission rod is provided with a tooth groove, the tooth groove is slidably connected with sliding teeth, and the tooth groove and the sliding teeth are connected by a No. 4 spring.

[0019] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0020] This solution achieves efficient protection for the detection probe through an opening and closing assembly. During the welding process, the opening and closing plate, driven by the piston plate, seals the detection port, using mechanical isolation to directly prevent welding spatter and high-temperature fumes from contacting the probe surface. This avoids the problem of decreased detection accuracy caused by impurities adhering to the probe in traditional devices. Simultaneously, the opening and closing of the plate is precisely controlled by the sliding piston plate, automatically closing during welding and automatically opening during detection. This ensures the probe's safety in the welding environment without affecting normal operation during the detection phase, significantly extending the probe's lifespan and maintaining long-term detection stability.

[0021] Meanwhile, the design of the probe focusing assembly in this solution provides the inspection probe with flexible and precise focusing adjustment capabilities. The piston rod drives the inspection probe to slide within the piston housing, allowing for rapid adjustment of the probe focal length according to different weld point locations and component sizes, thus solving the problem of insufficient focusing adjustment flexibility in traditional devices. Furthermore, in conjunction with the longitudinal and transverse sliding groove design of the support assembly, the mounting bracket and probe can achieve multi-dimensional position adjustment. Combined with the linear module's position control of the welding head, the probe can be precisely aligned with the welding area, ensuring clear inspection images even in welding scenarios involving small components, improving the accuracy and adaptability of defect identification.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to embodiments.

[0034] Example: Refer to Figures 1 to 8 A welding device for new energy vehicle parts with defect detection includes a support assembly 1. The support assembly 1 includes a base plate 11, a frame 13 is mounted on the base plate 11, a mounting frame 15 is mounted on the frame 13, a mounting ring 17 is mounted on the side wall of the mounting frame 15 through a linear module 16, a welding head 18 is provided inside the mounting ring 17, and an opening and closing assembly 2 is provided at the bottom of the mounting frame 15.

[0035] A longitudinal slide groove 12 is provided above the support component 1. A frame 13 is slidably connected in the longitudinal slide groove 12. A transverse slide groove 14 is provided in the frame 13. A mounting bracket 15 is slidably connected in the transverse slide groove 14.

[0036] The linear module 16 includes a motor 161 installed in the mounting bracket 15. The output end of the motor 161 is fixedly connected to a lead screw 162. A linear slider 163 is provided on the side wall of the lead screw 162. A mounting ring 17 is fixedly connected to the side wall of the linear slider 163.

[0037] Specifically: In support assembly 1, base plate 11 is slidably connected to frame 13 via longitudinal slide groove 12, and frame 13 is slidably connected to mounting bracket 15 via transverse slide groove 14, enabling flexible horizontal movement of mounting bracket 15 to accommodate welding position adjustments for components of different sizes. In linear module 16 on the side wall of mounting bracket 15, motor 161 drives lead screw 162 to rotate, and lead screw 162 drives linear slider 163 to slide up and down via threaded transmission, thereby enabling mounting ring 17 and welding head 18 to rise and fall, precisely controlling the welding height.

[0038] The opening and closing assembly 2 includes a detection port 21 and a piston groove 24 at the bottom of the mounting bracket 15. A detection probe 22 is provided in the detection port 21, and a piston plate 25 is slidably connected in the piston groove 24. The detection probe 22 is used to detect the welding effect of the parts after welding. An opening and closing plate 23 is provided at the bottom of the detection port 21. The opening and closing of the opening and closing plate 23 is controlled by the sliding of the piston plate 25. The opening and closing plate 23 is used to close the detection port 21 during welding.

[0039] The bottom of the lead screw 162 is provided with a lifting groove 27 and a spiral groove 29. A lifting rod 26 is inserted into the lifting groove 27, and a spiral slider 28 is slidably connected in the spiral groove 29. The spiral slider 28 is fixedly connected to the side wall of the lifting rod 26.

[0040] A prying rack 210 is slidably connected to the bottom of the piston groove 24, and a prying gear 211 is meshed with the prying rack 210. A prying plate 23 is fixedly connected to the side wall of the prying gear 211.

[0041] Specifically: the spiral groove 29 at the bottom of the lead screw 162 is slidably connected to the spiral slider 28 on the side wall of the lifting rod 26. The lifting rod 26 is inserted into the lifting groove 27 of the lead screw 162, realizing the conversion from rotation of the lead screw 162 to linear motion of the lifting rod 26. The lifting rod 26 is linked with the piston plate 25 in the piston groove 24. The opening and closing rack 210 at the bottom of the piston groove 24 is connected to the piston plate 25, and the opening and closing rack 210 meshes with the opening and closing gear 211. The opening and closing plate 23 is fixed on the side wall of the opening and closing gear 211, forming a transmission chain of "lead screw 162, lifting rod 26, piston plate 25, rack and pinion, opening and closing plate 23".

[0042] During operation, in the welding stage, motor 161 drives lead screw 162 to rotate. Helical groove 29 drives lifting rod 26 to move down along lifting groove 27 via helical slider 28, pushing piston plate 25 to slide in piston groove 24. Hydraulic oil in piston groove 24 causes piston plate 25 to drive opening and closing rack 210 to move horizontally. The rack meshes and drives opening and closing gear 211 to rotate, causing opening and closing plate 23 to close detection port 21. After welding is completed, lead screw 162 reverses and drives lifting rod 26 to move upward. Piston plate 25 returns to its original position. Opening and closing rack 210 moves in the opposite direction, causing opening and closing gear 211 to drive opening and closing plate 23 to open. Detection probe 22 detects weld joints through detection port 21. During welding, opening and closing plate 23 closes detection port 21, physically isolating welding spatter and high-temperature fumes, and preventing photosensitive element aging caused by direct sunlight. Automatic opening during detection does not affect detection. Combined with precise transmission, it ensures that the opening and closing timing matches the welding rhythm, improving probe lifespan and detection stability, and achieving coordinated operation of welding and protection.

[0043] The mounting bracket 15 is equipped with a probe focusing assembly 3, which is used to control the focusing of the detection probe 22. The probe focusing assembly 3 includes a piston housing 31 fixedly connected in the mounting bracket 15, a piston rod 32 slidably connected in the piston housing 31, and the detection probe 22 is installed at the bottom of the piston rod 32.

[0044] An oil groove 33 is provided inside the mounting bracket 15. A sliding plate 34 is slidably connected inside the oil groove 33. The oil groove 33 and the sliding plate 34 are connected by a spring 36. A sliding rod 35 is fixedly connected to one side of the sliding plate 34. The sliding rod 35 passes through the mounting bracket 15. The other end of the mounting bracket 15 abuts against a drive triangular block 37.

[0045] The mounting bracket 15 has a fixing component 4 on its side wall. The fixing component 4 includes a fixing groove 41, an unlocking groove 45 and an unlocking channel 48 that are opened in the mounting bracket 15. The unlocking groove 45 is connected to the fixing groove 41 through the unlocking channel 48. A fixing block 42 is slidably connected in the fixing groove 41. The fixing groove 41 and the fixing block 42 are connected by a second spring 44. The bottom of the fixing block 42 is inserted into a fixing slot 43. The fixing slot 43 is opened in the side wall of the sliding rod 35. An unlocking wedge 46 is slidably connected in the unlocking groove 45 through a third spring 47.

[0046] Specifically: the piston housing 31 in the mounting bracket 15 is slidably engaged with the piston rod 32, and the detection probe 22 is fixed at the bottom of the piston rod 32; the sliding plate 34 in the oil groove 33 is elastically supported by the first spring 36, and the sliding rod 35 connected to the sliding plate 34 passes through the mounting bracket 15 and abuts against the driving triangular block 37; in the fixing assembly 4, the fixing insert 42 in the fixing groove 41 is engaged into the fixing slot 43 of the sliding rod 35 by the second spring 44, and the unlocking wedge 46 in the unlocking groove 45 is reset by the third spring 47 and communicates with the fixing groove 41 through the unlocking channel 48.

[0047] During operation, the drive triangular block 37 is pressed, pushing the sliding rod 35 to move horizontally. The sliding plate 34 compresses the first spring 36 and squeezes the hydraulic oil in the oil groove 33. The hydraulic oil transmits pressure to the piston housing 31, pushing the piston rod 32 to move the detection probe 22 up and down to achieve initial focusing adjustment. The distance the lens moves during focusing is related to the distance the welding head 18 descends. The greater the distance the welding head 18 descends, the longer the distance the drive triangular block 37 drives the sliding rod 35 to move horizontally, which in turn makes the detection probe 22 descend a greater distance. The distance the welding head 18 descends... The larger the value, the narrower the welded parts. Within a reasonable range, the smaller the distance between the detection probe 22 and the parts, the clearer the image it outputs. After focusing, the second spring 44 pushes the fixed insert 42 into the fixed slot 43, locking the position of the sliding rod 35 to maintain the probe's focal length. After one detection, the piston plate 25 resets and abuts against the unlocking wedge 46. Through the transmission of hydraulic oil in the unlocking channel 48, the fixed insert 42 disengages from the slot, and the sliding rod 35 resets under the action of the first spring 36, driving the probe back to its initial position.

[0048] A rotating assembly 5 is provided inside the base plate 11. The rotating assembly 5 includes a rotating groove 52 opened on the base plate 11. A fixed shaft 53 is fixedly connected inside the rotating groove 52. A rotating gear 54 is rotatably connected to the side wall of the fixed shaft 53 through a torsion spring. A worktable 51 is fixedly connected to the top of the rotating gear 54.

[0049] A transmission rod 56 is provided on the side wall of the rotating gear 54. The transmission rod 56 is slidably connected in the transmission groove 55. The transmission groove 55 and the transmission rod 56 are connected by a No. 5 spring 511. A toothed groove 57 is provided at the bottom of the transmission rod 56. A sliding tooth 58 is slidably connected in the toothed groove 57. The toothed groove 57 and the sliding tooth 58 are connected by a No. 4 spring 59.

[0050] The sliding tooth 58 is driven by the hydraulic assembly 6. The hydraulic assembly 6 includes a hydraulic groove 61 opened in the transmission rod 56. A hydraulic rod 62 is slidably connected in the hydraulic groove 61. A rectangular groove 63 is opened at the bottom of the hydraulic rod 62. The rectangular groove 63 is used to abut against the wedge rod 64. The wedge rod 64 is fixedly connected to the top of the sliding tooth 58.

[0051] Specifically: The rotating component 5 and the hydraulic component 6 form a progressive transmission structure: the fixed shaft 53 in the rotating groove 52 of the base plate 11 is connected to the rotating gear 54 through a torsion spring, and the top of the rotating gear 54 is fixed to the worktable 51; the transmission rod 56 on the side wall of the rotating gear 54 slides in the transmission groove 55 and is reset by the No. 5 spring 511; the sliding teeth 58 in the bottom tooth groove 57 of the transmission rod 56 are elastically supported by the No. 4 spring 59; the hydraulic rod 62 of the hydraulic component 6 slides in the hydraulic groove 61 of the transmission rod 56, and its bottom rectangular groove 63 abuts against the wedge rod 64 at the top of the sliding teeth 58 and controls its descent.

[0052] During operation, the hydraulic oil in the hydraulic channel 510 transmits hydraulic oil, causing the transmission rod 56 and hydraulic rod 62 to slide during the welding process as the welding head 18 descends. Simultaneously, the wedge rod 64, which is pressed by the hydraulic rod 62, returns to the rectangular groove 63 under the action of the fourth spring 59 as the hydraulic rod 62 slides. This controls the sliding teeth 58 to retract into the tooth groove 57 and lose engagement with the rotating gear 54, without affecting the rotation of the worktable 51, thus ensuring the stability of the welding process. After welding is completed, as the piston plate 25 resets, the transmission rod 56 and hydraulic rod 62 slide in opposite directions. At this time, the wedge rod 64 is pressed again by the hydraulic rod 62, thereby controlling the sliding teeth 58 to re-engage with the rotating gear 54. As the transmission rod 56 slides, it drives the rotating gear 54 to rotate around the fixed shaft 53, realizing the rotation of the worktable 51 and enabling the detection probe 22 to perform omnidirectional detection.

[0053] The working principle of this invention is as follows:

[0054] The opening and closing assembly 2 enables intelligent opening and closing of the detection port 21, achieving switching between welding protection and detection. During the welding stage, the motor 161 drives the lead screw 162 to rotate. The spiral groove 29 at the bottom of the lead screw 162 drives the lifting rod 26 to move down along the lifting groove 27 via the spiral slider 28, pushing the piston plate 25 in the piston groove 24 to slide. The piston plate 25 moves in conjunction with the opening and closing rack 210, and the rack meshes to drive the opening and closing gear 211 to rotate, causing the opening and closing plate 23 to close the detection port 21, physically isolating welding spatter, high-temperature fumes, and strong light, and preventing the photosensitive element of the detection probe 22 from aging. After welding is completed, the lead screw 162 reverses to drive the lifting rod 26 to move up, the piston plate 25 resets, and the opening and closing rack 210 moves in the opposite direction to cause the opening and closing gear 211 to drive the opening and closing plate 23 to open. The detection probe 22 then detects the weld point through the detection port 21, realizing automated switching between protection during welding and openness during detection.

[0055] The probe focusing assembly 3 and rotating assembly 5 ensure accurate and comprehensive detection. During focusing adjustment, the drive triangular block 37 pushes the sliding rod 35, causing the sliding plate 34 to compress the first spring 36 and squeeze the hydraulic oil in the oil groove 33. The hydraulic oil pushes the piston rod 32 inside the piston housing 31, causing the detection probe 22 to slide up and down for focusing. After focusing, the fixing block 42 of the fixing assembly 4 is inserted into the slot of the sliding rod 35 to lock the focus. When unlocking, the lock is released through hydraulic transmission. In the rotating assembly 5, during welding, the hydraulic assembly 6 controls the sliding teeth 58 to retract, keeping the worktable 51 stable. During the detection phase, the sliding teeth 58 reset and mesh with the rotating gear 54. The transmission rod 56 drives the rotating gear 54 to rotate, causing the worktable 51 to rotate. Combined with the probe focusing adjustment, this ensures that the detection probe 22 can perform multi-angle and clear detection of the weld point, improving the accuracy of defect identification.
