Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device for electric vehicle power circuit boards. Background Technology

[0002] Electric vehicle power circuit board (ECU) welding equipment is crucial in the manufacturing of electric vehicles, directly impacting the safety, reliability, and performance of the battery system. ECUs comprise multiple functional modules, including the battery management system, charging circuitry, and power conversion circuitry. Welding technology ensures stable battery charging and discharging by guaranteeing robust connections between ECU components. Common welding methods include wave soldering, reflow soldering, and manual soldering. Wave soldering is suitable for mass production, reflow soldering allows for precise temperature control and is suitable for high-precision components, while laser welding provides a high-precision solution for advanced battery management systems. With the advancement of smart manufacturing, automated welding systems are becoming increasingly widespread, improving production efficiency and welding quality. In the future, ECU welding equipment will further develop towards intelligence and automation to address the challenges of increasingly complex electric vehicle battery technology and ever-increasing performance requirements. Therefore, selecting appropriate welding equipment and continuously optimizing the technology are crucial factors driving the development of the electric vehicle industry.

[0003] For example, Chinese patent publication number "CN118237689A" discloses "a circuit board welding device", which includes a workbench with a placement platform at the top center of the workbench. First cylinders are slidably connected to both ends of the workbench at the placement platform. A first motor is installed at the output end of the first cylinder, and a mounting plate is installed at the output end of the first motor. U-shaped frames are slidably connected to both ends of the mounting plate at the first motor. A stop block is installed at the bottom of the U-shaped frame, and a first electric telescopic rod is installed at the top of the U-shaped frame. A pressure block is installed at the output end of the first electric telescopic rod. Second electric telescopic rods are installed at both ends of the mounting plate, and the output ends of the second electric telescopic rods are fixedly connected to the U-shaped frame. This invention, through the design of the first motor, first cylinder, and first electric telescopic rod, allows the circuit board to be flipped while clamped, thereby improving welding efficiency.

[0004] In actual use, the aforementioned electric vehicle power circuit board welding equipment requires external equipment or manual labor for loading and unloading. However, manual or external equipment operation significantly reduces production efficiency because this intermittent operation cannot match the working speed of the welding equipment, leading to extended production cycles. Secondly, manual operation is prone to errors, such as misplacing circuit boards or damaging components, thus affecting welding quality and increasing rework and scrap rates. Long-term reliance on manual loading and unloading can also lead to operator fatigue, increasing the risk of errors and potentially negatively impacting employee health. Furthermore, the use of manual or external equipment reduces the actual utilization rate of the equipment, wasting production time. Inconsistencies in the loading and unloading process also hinder standardized production, affecting the consistency of welding results. Finally, this operating method increases labor and equipment maintenance costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a welding device for electric vehicle power circuit boards. The device uses a feeding claw and slot in an automatic feeding assembly to grasp the circuit board stored in a storage assembly. Simultaneously, a first motor drives a sprocket to rotate, causing the feeding claw, slot, and circuit board to slide on a baffle between the sprocket and the feeding frame. This automatic feeding improves production efficiency, reduces human error, ensures accurate and consistent feeding, and lowers labor intensity and safety risks. Although the initial investment is high, it offers long-term cost savings through increased efficiency and reduced waste, supports large-scale production, and solves the aforementioned technical problems.

[0029] Compared with the prior art, the present invention provides a welding device for electric vehicle power circuit boards, which has the following beneficial effects:

[0030] 1. The electric vehicle power circuit board welding equipment of the present invention uses a picking claw and a slot in the automatic feeding component to pick up the circuit board stored in the storage component. Simultaneously, a first motor drives a sprocket to rotate, and the sprocket causes the picking claw, the slot, and the circuit board to slide on a baffle between the sprocket and the feeding frame, thereby achieving automatic feeding.

[0050] The lateral movement assembly includes a sliding frame 35 fixed to the outer wall of a fixed frame 34, which supports and fixes the sliding frame 35. A sliding sleeve 36 is slidably connected to the outer side of the sliding frame 35, limiting the sliding sleeve 36 so that it slides on the outer side of the sliding frame 35.

[0052] The material gripping assembly includes a limiting frame 5 rotatably connected to the outer wall of the mounting plate 45 on the opposite side. The mounting plate 45 supports and limits the limiting frame 5, allowing it to rotate outside the mounting plate 45. The limiting frame 5 is fixedly connected to the output end of the third motor 46, which supports and fixes the limiting frame 5 and drives it to rotate.

A connecting rod 63 is fixedly connected to the outer side of the output end of the rotating disk 62, which supports and fixes the connecting rod 63. At the same time, the rotating disk 62 drives the connecting rod 63 to rotate. A welding head 64 is fixedly connected to the end of the connecting rod 63, which supports and fixes the welding head 64.

[0054] A conveyor belt 12 is provided on the inner side of the bottom of the first support frame 11. The first support frame 11 supports the conveyor belt 12. One end of the conveyor belt 12 near the first support frame 11 is located at the bottom of the welding head 64. The soldered circuit board 27 can fall directly onto the conveyor belt 12 and be transported out.

[0055] The two gas springs 43 can be independently controlled by a sensor (an infrared sensor used to monitor the relative position between the circuit board 27 and the welding head 64). By controlling the gas springs 43 on both sides individually, the clamping point can be moved.

[0056] When using;

[0057] First, the circuit board 27 is placed into the storage tank 25. Then, the first motor 21 drives the sprocket 22, which in turn drives the picking claw 23 to rotate synchronously. The picking claw 23 uses the slot 24 to grab the circuit board 27 inside the storage tank 25. Then, the circuit board 27 is moved inside the baffle. After that, the circuit board 27 is moved from one end of the feeding rack 2 to the other end, and then the drive is stopped.

[0058] Driven by the cylinder 41 itself, the cylinder 41 moves to the outside of the first slide bar 4. At the same time, the cylinder 41 drives the support plate 42 to move to one side of the rotating frame 32, and drives the telescopic component and the material gripping component to move synchronously.

[0059] After the material gripping assembly is aligned with the circuit board 27, the air rod 43 uses the support plate 42 as the stress point to drive the mounting plate 45 to move towards the side of the circuit board 27, and at the same time, it drives the material gripping assembly to move synchronously. After the moving plate 55 contacts the circuit board 27, the moving plate 55 stops moving, but the limiting frame 5 continues to move, thereby limiting the clamping rod 52 through the slide groove 51, causing the clamping rod 52 to move in the opposite direction, thereby clamping the circuit board 27.

[0060] The cylinder 41 drives the support plate 42, internal structure and discharge port 26 to move away from the rotating frame 32 in sequence, driving the circuit board 27 to move above the welding table 61, and welding the circuit board 27 through the welding head 64.

[0061] After welding is completed, the air rod 43 simultaneously moves the material gripping assembly to a relatively distant side, releasing the circuit board 27 and causing it to fall onto the conveyor belt 12, which then transports the circuit board 27 out.
