Description

Technical Field

[0001] This invention belongs to the technical field of precision welding equipment for 3C products, specifically relating to an AR welding equipment with four functions in one X-axis and Y-axis. It is suitable for integrated automated welding scenarios of flux dispensing, product alignment, pulse precision welding, and post-weld AOI inspection for small precision ribbon cables, and is widely used in the mass precision welding production process of consumer electronics flexible ribbon cables. Background Technology

[0002] Flexible ribbon cable soldering is a core and critical process in the manufacturing of 3C electronic products. Due to the characteristics of flexible ribbon cables—small size, irregular shape, dense solder joints, and extremely high alignment precision requirements—the soldering quality directly determines the assembly yield, operational stability, and lifespan of electronic products. Currently, the mainstream production methods in the industry are manual soldering and simple automatic pulse soldering, both of which have significant technical shortcomings and are difficult to meet the demands of high-precision, high-yield, and high-consistency mass production.

[0003] The existing technology mainly has the following technical problems: First, manual soldering is prone to defects and large errors. Traditional manual soldering relies on the operator's experience, which easily leads to soldering defects such as cold solder joints, false solder joints, bridging, and short circuits. Manual alignment is inaccurate, and the soldering temperature cannot be precisely controlled, resulting in extremely low product soldering consistency. In addition, manual production is costly and inefficient, making it unsuitable for large-scale standardized production.

[0004] Secondly, traditional automated equipment has limited functionality and fragmented processes. Existing automatic pulse welding equipment only has a single welding function and requires separate dispensing equipment, manual alignment, and separate testing equipment for segmented operations. The equipment layout is scattered, the production line occupies a large area, the process connection is cumbersome, the equipment investment cost is high, and the production cycle is slow.

[0005] Third, the welding temperature is uncontrollable and easily damages the product. Traditional welding equipment cannot achieve precise point-to-point temperature control, resulting in large temperature fluctuations during welding. The high temperature during welding can easily be conducted to the wiring harness and components, causing product failure due to high temperature, damage to the wiring harness, and a high product scrap rate.

[0006] Fourth, the welding pressure is not adjustable and the alignment accuracy is low. Traditional welding equipment mostly adopts a rigid downward pressure structure without real-time pressure feedback and precise adjustment function. The welding pressure is unstable, which can easily lead to problems such as damage to the wiring and incomplete welding. At the same time, it lacks a high-precision visual alignment structure, resulting in large alignment errors for irregular wiring and dense weld points.

[0007] Fifth, it lacks integrated post-weld inspection functionality. After welding is completed on traditional production lines, the products need to be manually transferred to independent testing equipment for inspection. This results in delayed inspection, an inability to remove defective products in real time, poor production traceability, and difficulty in achieving closed-loop quality control.

[0008] In summary, there is an urgent need for an AR welding equipment that integrates dispensing, alignment, precision welding, and post-weld inspection into a single unit with four functions: X-axis and Y-axis. This would address the industry pain points of existing equipment, such as fragmented processes, low precision, poor temperature control, uncontrollable pressure, and low product yield. Summary of the Invention

[0034] Example This invention discloses an AR welding equipment with four functions in one X-axis and Y-axis. The overall structure adopts a modular integrated architecture, consisting of four core modules: dispensing and alignment gantry linear motor module A, alignment module, HB welding module D, and re-inspection module F. A single unit integrates four functions: flux dispensing, product alignment, pulse precision welding, and post-weld AOI inspection. The entire process is automated, requiring no manual handling or intervention, and is suitable for high-precision batch welding production of 3C flexible ribbon cables.

[0035] In terms of equipment alignment and dispensing operations, the dispensing and alignment gantry linear motor module A serves as the core mechanism for the horizontal and vertical movement of the equipment. It forms a high-precision gantry moving platform through the X-axis linear motor 101 and the Y-axis linear motor 105, and is paired with the Z-axis KK module 107 and a 100W servo motor 106 to achieve precise three-dimensional displacement adjustment. During operation, the upper CCD module 103, in conjunction with the CameraFPC304, forms a binocular vision recognition structure, accurately identifying and calibrating the positions of the SystemFPC304 and CameraFPC304. The dispensing valve 104 moves with the gantry module, achieving precise flux dispensing in the solder joint area, ensuring uniform flux application and accurate positioning, laying the foundation for subsequent precision welding. The cable chain 108 collects the equipment cables throughout the process, preventing cable pulling and wear, and improving equipment operational stability.

[0036] For precise alignment and adsorption fixation of the product, the alignment module uses a vacuum generator 202 in conjunction with a nozzle module 205 to achieve stable adsorption and fixation of flexible cables. A cylinder module 201 provides stable downward pressure, and an R-axis servo motor 203 drives the nozzle module 205 to rotate and adjust the workpiece at multiple angles, adapting to the alignment requirements of irregularly shaped cables and multi-angle solder joints. The nozzle module 205 has a built-in heating rod and temperature sensor 302, enabling precise temperature control for auxiliary operation. Combined with a synthetic stone grounding 301, it effectively eliminates electrostatic interference, preventing electrostatic damage to precision components. A pressure sensor 204 collects the alignment pressure in real time, ensuring stable workpiece contact and preventing squeezing damage.

[0037] In precision pulse welding operations, the HB welding module D uses a servo motor and the Z-axis KK module 107 to drive the welding head 408 for precise lifting and lowering. Combined with the pressure sensor 204, this forms a closed-loop pressure control system that can monitor and precisely adjust the welding pressure in real time, with a minimum controllable pressure as low as 0.2 kgf, perfectly suited for the delicate welding process of tiny, dense weld points. Simultaneously, the equipment incorporates a pulse current control system for precise point-to-point temperature regulation, stabilizing the temperature difference of the welding head 408 within ±3°C, completely solving the problem of large temperature fluctuations in traditional welding. During welding, the eddy current tube 406, in conjunction with the universal curved tube 407, forms a directional air-cooling structure, continuously dissipating heat from the welding area and rapidly dissipating the high welding temperature. This effectively prevents problems such as deformation, failure, and aging of cables and precision components due to high temperatures. The PI film take-up and untake-off shaft 403 can neatly arrange the welding cables, preventing wrinkles and misalignment, and improving welding neatness.

[0038] In terms of integrated post-weld inspection, the re-inspection module F achieves adaptive height adjustment through a servo motor and the Z-axis KK module 107, and completes micron-level position fine-tuning with the precision adjustment slide 503 to ensure inspection accuracy. The CCD module 504, high-magnification lens 505, and dedicated light source 506 work together to integrate 2D planar inspection and 3D stereoscopic inspection functions. It can scan the welding area from all directions, accurately identify various welding defects such as cold welds, false welds, bridging short circuits, missing welds, and misalignments, and complete post-weld quality screening in real time, automatically marking defective products and realizing integrated closed-loop operation of welding and inspection.

[0039] The equipment boasts a high degree of automation, automatically completing the entire process from dispensing, alignment, welding, to inspection. Furthermore, it allows for rapid product changeovers by replacing specialized carriers and using positioning pins, adapting to the production of various ribbon cable specifications. The equipment features high process integration, a small footprint, high precision, and strong stability, effectively solving the industry problems of cumbersome processes, low yield, high cost, and uncontrollable quality in traditional ribbon cable welding production.
