Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device for the internal cable trays of a medical isolation power supply cabinet. Background Technology

[0002] In the field of medical isolation power cabinet manufacturing, U-shaped cable trays are core wiring components, and their welding quality directly affects the safety and stability of the equipment. Currently, laser welding technology is mostly used for welding these cable trays to adapt to intelligent welding systems, but there are still significant pain points in the existing technology.

[0003] First, the irregular shape of the U-shaped cable tray makes positioning difficult. Traditional clamping devices struggle to achieve uniform force in multiple directions, easily causing damage to the sheet metal or positioning deviations. Furthermore, the welding mechanism's movement and clamping actions are disconnected, affecting the accuracy of laser welding. Second, during intelligent welding, the weld detection components are susceptible to laser radiation damage, making it difficult to achieve coordinated welding and monitoring. The lack of a closed-loop quality control mechanism leads to poor weld uniformity and frequent defects such as incomplete welds, failing to meet the stringent requirements of medical equipment. Third, existing equipment has limited adaptability and cannot be compatible with welding U-shaped cable trays of different specifications. Moreover, pre-welding burr removal, post-welding slag removal, and sheet metal flattening processes must be completed separately, contradicting the integrated operation requirements of intelligent welding systems and resulting in low production efficiency. Therefore, we propose a cable tray welding device for medical isolation power cabinets. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a welding device for the internal cable trays of a medical isolation power supply cabinet, which has the following beneficial effects: 1. This invention, through the collaborative design of the clamping and moving components, utilizes the U-shaped plate's wraparound structure to adapt to the shape of the U-shaped groove. Combined with the synchronous encircling clamping of multiple first electric telescopic rods and real-time feedback from pressure sensors, it achieves precise control of the clamping force, preventing damage to the plate and ensuring positioning stability. Simultaneously, the I-shaped clamping plate merges synchronously with the clamping action to form an integrated guide track.

This effectively solves the pain points of positioning deviation and unstable movement in existing technologies, laying the foundation for high-precision welding.

[0016] 2. This invention relies on the intelligent linkage between the welding and detection components. A third electric telescopic rod drives the welding head to micro-oscillate, forming a corrugated weld seam and enhancing the mechanical strength of the weld joint. Simultaneously, the rotating sleeve drives the rack and pinion to mesh with the second spur gear, enabling intelligent avoidance between the industrial camera and the laser beam. This protects the detection components while simultaneously acquiring real-time images of the weld seam. Image recognition technology is used to locate and monitor the weld seam, forming a closed-loop control system of "posture adjustment - welding execution - quality feedback." Compared to existing technologies, this effectively avoids defects such as incomplete welds and uneven weld seams, significantly improving the stability and reliability of welding quality, meeting the stringent requirements of medical equipment.

[0017] 3. This invention features an adjustable multi-component design. The unfolding shaft can drive the grinding component to unfold or retract, adapting to different specifications of U-shaped grooves. The adjustable characteristics of components such as the flexible pressure plate and the second electric telescopic rod further expand the equipment's adaptability. Simultaneously, the grinding component integrates pre-welding burr removal, post-welding slag removal, and plate flattening functions. The limiting frame simultaneously achieves plate clamping and chamfering grinding, eliminating the need for additional auxiliary equipment. This integrated process effectively reduces process flow and equipment investment, solving the problems of insufficient adaptability and low operating efficiency in existing technologies, and significantly improving production efficiency and practicality.

[0037] In this embodiment, the grinding assembly 52 includes an upper mounting chamber 521 fixedly connected to the first T-shaped block 421. The inner side of the upper mounting chamber 521 is rotatably connected to a counter-threaded rod 522. The outer side of the counter-threaded rod 522 is threadedly connected to two mutually symmetrical adjusting blocks 523. The upper end of the adjusting block 523 is slidably connected to a baffle 524. The near ends of the two baffles 524 are fixedly connected to the upper mounting chamber 521.

[0039] In this embodiment, the four fulcrums of the adjusting plate 529 are all rotatably connected to the unfolding shaft 5210 via a rotating shaft. The lower end of the unfolding shaft 5210 is fixedly connected to the lower mounting chamber 5211.

Two sliding grooves are opened at the lower end of the limit frame 5216. Two mutually symmetrical grinding discs 5217 are fixedly connected to the inner side of the sliding groove of the limit frame 5216. The lower end of the limit frame 5216 is slidably connected to the plate through the sliding groove.

[0040] Specifically, the unfolding shaft 5210 deflects around its connection point with the adjusting plate 529, causing the lower mounting chamber 5211 to unfold or retract, adapting to different specifications of U-shaped cable trays; the lower mounting chamber 5211 provides mounting support for the fourth motor 5212 and the grinding shaft 5213; the fourth motor 5212 provides rotational power to the grinding shaft 5213; the grinding shaft 5213 is the grinding execution component, with two on the front for cleaning weld burrs before welding and two on the rear for cleaning weld slag after welding; ball bearings 521... 4. Reduce friction between the lower mounting chamber 5211 and the plate to ensure smooth movement during the grinding process; the spring telescopic plate 5215 provides elastic tension through the built-in spring, driving the limit frame 5216 to fit tightly against the plate; the limit frame 5216 presses the vertical plate and the flat plate together to prevent incomplete welding, and also bears the load of the top plate 417 and related components to ensure structural stability; the grinding disc 5217 achieves grinding and chamfering by sliding contact with the upper end of the vertical plate, avoiding scratches during subsequent assembly.

[0041] Working principle: When in use, the U-shaped wire trough plate to be welded is first placed on the preset position on the upper end of the workbench 2 inside the chassis 1. The multiple first electric telescopic rods 32 on the inner side of the U-shaped plate 31 are activated to move synchronously. Their output shafts drive the flexible pressure plate 33 to clamp the plate from multiple directions. During the process, the pressure sensor on the inner side collects the clamping force data in real time and feeds it back to the control system to ensure that the clamping force is within the preset safety range. This achieves stable positioning of the plate and avoids damaging the surface of the plate, thus completing the precise fixation before welding the U-shaped wire trough. After the flexible pressure plate 33 is clamped in place, the I-shaped clamping plate 411 fixedly connected to its upper end merges synchronously to form an integrated guide track. The control system starts the drive program of the moving component 41: after receiving the command, the first motor 415 drives the first spur gear 414 to rotate. The first spur gear 414 drives the mounting frame 413 to move smoothly along the guide track of the I-shaped clamping plate 411 through meshing transmission with the toothed plate 412. During this period, the roller 416 rolls inside the groove of the I-shaped clamping plate 411, effectively reducing the moving resistance and ensuring the displacement accuracy, so that the mounting frame 413 drives the top plate 417 and the cylinder 418 to accurately enter the inner welding area of ​​the U-shaped wire groove plate, providing a precise positioning basis for subsequent intelligent welding. After the moving component 41 is positioned, the control system starts the attitude adjustment program of the welding component 42: after receiving the command, the cylinder 418 outputs the shaft to drive the first T-block 421 to lift upward. The first T-block 421 drives the first connecting rods 422 on both sides to transmit synchronously through the cavity structure on its inner side, which in turn drives the second connecting rod 423 to open and deflect in opposite directions around the rotating shaft connected to the top plate 417. The second connecting rod 423 drives the connecting shaft 425 to move synchronously through the fixed sleeve 424. The connecting shaft 425 drives the C-shaped clamp 426 and the mounting block 429 to move precisely, so that the welding head body 428 inside the rotating sleeve 427 is precisely aligned with the preset weld position on the inner wall of the groove. Subsequently, the second electric telescopic rod 4210 inside the mounting block 429 is activated, and its output shaft drives the welding head body 428 to move downward through the spring telescopic rod 4211. The flexible buffering characteristics of the spring telescopic rod 4211, combined with the feedback from the pressure sensor inside the second electric telescopic rod 4210, make the welding head body 428 smoothly fit against the weld surface, completing the posture calibration before laser welding. Entering the intelligent welding stage, during the mobile welding process, the third electric telescopic rod 511 continuously receives control signals, and its output shaft extends and retracts back and forth at a preset frequency, driving the rotating sleeve 427 to reciprocate and reset within the C-shaped clamp 426. The rotating sleeve 427 drives the welding head body 428 to perform adaptive micro-swing through the sleeve transmission. The welding head body 428 achieves elastic extension and retraction by squeezing the spring telescopic rod 4211 through the lever principle, which not only ensures the stable connection between the welding head body 428 and the second electric telescopic rod 4210, but also makes the weld seam form a preset corrugated structure, effectively improving the mechanical strength of the welded joint and meeting the automation adaptation requirements of the intelligent welding system. Meanwhile, the detection component 51 and the welding component 42 achieve intelligent linkage: when the rotating sleeve 427 rotates, it synchronously drives the rack 512 to deflect. The rack 512 drives the second spur gear 513 to rotate in opposite directions around the rotating shaft connected to the second connecting rod 423 through meshing transmission. In turn, the rotating shaft drives the protective shell 514 and the industrial camera 515 to perform synchronous attitude adjustment, so that the detection angle of the industrial camera 515 and the laser welding spot of the welding head body 428 form intelligent avoidance. This avoids laser damage to the lens of the industrial camera 515 and ensures that the industrial camera 515 can collect images of the weld position and the surrounding welding status in real time. The image recognition technology completes the weld positioning and welding quality real-time monitoring, and feeds the data back to the control system to form an intelligent closed-loop control. Before and after the welding process, the grinding component 52 automatically intervenes according to the preset logic: Before welding, the control system starts the third motor 526, whose output shaft drives the second bevel gear 527 to rotate. The second bevel gear 527 drives the first bevel gear 525 to rotate synchronously, which in turn drives the opposing threaded rod 522 to rotate around the axis inside the upper mounting chamber 521. The opposing threaded rod 522 drives the two adjusting blocks 523 to move in opposite directions through the threaded engagement and the limiting effect of the baffle 524. The adjusting blocks 523 drive the third connecting rod 528 to deflect, which in turn drives the adjusting plate 529 to move downward. The adjusting plate 529 applies downward pressure to the four unfolding shafts 5210. The unfolding shafts 5210 deflect around the rotating shaft connected to the adjusting plate 529 as the axis, and achieve stable displacement through the ball bearings 5214 at the lower end of the lower mounting chamber 5211, so that the four unfolding shafts 5210 drive the grinding shaft 5213 to accurately fit the weld seams on both sides of the inner side of the wire groove plate. Subsequently, the fourth motor 5212 starts, driving the grinding shaft 5213 to rotate. The two front grinding shafts 5213 complete the pre-treatment of the weld seam and remove burrs, while the two rear grinding shafts 5213 clean the weld slag after welding is completed. At the same time, the four unfolding shafts 5210 unfold and flatten the flat plate below, effectively avoiding the problem of edge warping caused by thermal deformation during the welding process. As the adjusting plate 529 moves downward, it simultaneously drives the two spring telescopic plates 5215 to unfold. The spring telescopic plates 5215 drive the limiting frame 5216 to tightly press the vertical plate and fit it against the flat plate through the tension of the built-in spring, preventing welding defects during the welding process. The limiting frame 5216 drives the grinding disc 5217 to press the upper end of the vertical plate. When the moving component 41 moves the entire welding mechanism, the grinding disc 5217 simultaneously completes the grinding and chamfering of the upper end of the vertical plate, avoiding scratches during subsequent assembly. At the same time, the limiting frame 5216 bears the load of the top plate 417 and related components, ensuring the stability of the overall structure during the welding process.

[0042] Throughout the entire operation, the moving component 41 drives the welding component 42 and the auxiliary mechanism 5 to move smoothly along the plate according to the welding path preset by the control system. Through the intelligent linkage, data feedback and real-time adjustment of each component, the U-shaped groove is fully automated and high-precision laser welding is completed.
