Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to an automated assembly line for new energy epoxy high-voltage DC contactors. Background Technology

[0002] In the new energy field, epoxy high-voltage DC contactors play a crucial role. Traditional epoxy high-voltage DC contactor assembly lines rely primarily on manual operation for the assembly of the moving magnetic core assembly, leading to numerous problems. Manual assembly is inefficient and cannot meet the ever-increasing market demand, especially given the rapid development of the new energy industry and the expanding production scale which places higher demands on assembly speed. The precision of manual assembly is difficult to guarantee, easily leading to inaccurate component placement and inconsistent assembly force due to human factors, thus affecting product performance and reliability, and increasing the defect rate. Furthermore, manual assembly is labor-intensive, requiring significant manpower and high skill levels, increasing labor and training costs for enterprises. In addition, traditional assembly methods struggle to achieve precise monitoring and data recording of the assembly process, hindering production optimization and quality traceability.

[0003] Therefore, developing an automated assembly line to solve these problems is of great practical significance. Summary of the Invention

[0004] The purpose of this utility model is to provide an automated assembly line for epoxy high-voltage DC contactors used in new energy vehicles, power systems and other fields, which can significantly improve production efficiency, reduce labor costs, improve product quality stability, and meet the needs of large-scale industrial production, thereby solving the above-mentioned technical problems.

[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: An automated assembly line for new energy epoxy high-voltage DC contactors includes, in sequence, an end cap assembly machine, a moving magnetic core assembly machine, a moving contact assembly machine, a stationary arc extinguishing cover feeding machine, a coil assembly machine, a mechanical parameter testing machine, a metal shell assembly and electrical testing machine, and a shell assembly machine. The moving magnetic core assembly machine is one of the key parts of the entire assembly line. It includes a moving magnetic core assembly frame, a turntable mechanism rotatably mounted on the moving magnetic core assembly frame, and a circumferential array of transport fixtures on the turntable mechanism. Along the circumference of the turntable mechanism, a magnetic core assembly device, a shaft assembly device, a snap ring assembly device, and a finished product unloading device are arranged sequentially. A dust blowing device is provided between adjacent finished product unloading devices and magnetic core assembly devices to clean dust and impurities during the assembly process, ensuring a clean assembly environment. A first detection component is provided between adjacent magnetic core assembly devices and shaft assembly devices, a second detection component is provided between adjacent shaft assembly devices and snap ring assembly devices, and a snap ring vision inspection component is provided between adjacent snap ring assembly devices and finished product unloading devices. These detection devices can monitor and control the quality of each link in the assembly process in real time, ensuring the accuracy of assembly and product quality.

[0006] Furthermore, the magnetic core assembly device includes a magnetic core vibratory feeder mounted on a moving magnetic core assembly frame. The vibratory feeder can orderly transport magnetic cores to the output end. The output end is equipped with a magnetic core baffle assembly, which controls the quantity and rhythm of magnetic core output, facilitating subsequent gripping operations. A magnetic core transport bracket is located on one side of the baffle assembly, and a magnetic core transport lateral movement assembly is located on the other side. A magnetic core transport vertical movement assembly is fixed to the output end of the lateral movement assembly, and a magnetic core gripping finger cylinder is located at the output end of the vertical movement assembly. This combination of multi-level movement components and gripping cylinders enables precise movement and gripping of the magnetic cores in space, accurately transporting the magnetic cores from the vibratory feeder to the transport fixture of the turntable mechanism, ensuring accurate assembly of the magnetic cores.

[0007] Furthermore, the shaft assembly device includes a shaft vibration feeder, which can output shaft parts in an orderly manner. A shaft sorting mechanism is vertically movable in its output direction, which can sort the shafts for subsequent inspection and assembly operations. A shaft length / shortness detection component is located on one side of the shaft sorting mechanism. This component includes a shaft length / shortness detection bracket with insertion holes, on which a detection optical fiber is inserted. The detection optical fiber can accurately detect the length of the shaft, ensuring that the shaft length meets assembly requirements and avoiding assembly problems caused by unqualified shaft lengths. A shaft loading and handling robot is movably located between the shaft sorting mechanism and the shaft length / shortness detection component. This robot includes an XZ translation component, and the output end of the XZ translation component is equipped with a shaft finger cylinder, which can transport the qualified shafts to the appropriate assembly position. The shaft length detection component has a height-adjustable shaft direction adjustment mechanism on one side. The shaft direction adjustment mechanism includes a shaft direction adjustment bracket, a lifting cylinder on one side of the shaft direction adjustment bracket, and a flipping seat at the output end of the lifting cylinder. The flipping seat is driven to flip by a cylinder. The other end of the flipping seat has a flipping shaft clamping finger cylinder along the horizontal direction. This mechanism can adjust the direction of the shaft to ensure that the shaft is in the correct direction during assembly and improve the accuracy of assembly.

[0008] Furthermore, the snap ring assembly device includes a snap ring vibratory feeder, the output end of which is equipped with a receiving fixture for receiving snap rings. A clamping assembly is located in front of the snap ring vibratory feeder, detachably mounted on the receiving fixture, capable of clamping and positioning the snap ring. A push spring assembly is movably mounted on the clamping assembly, and a servo drive motor is mounted on the clamping assembly. The servo drive motor drives the push spring assembly to reciprocate via a lead screw. This structure allows the snap ring to be precisely installed into the corresponding assembly position, ensuring the assembly quality and stability of the snap ring.

[0009] Furthermore, the finished product unloading device includes an unloading moving XZ component. The output end of the unloading moving XZ component is equipped with an unloading finger cylinder, which can accurately grab and transport the assembled finished product from the transport fixture of the turntable mechanism to the designated unloading position, thereby realizing automatic unloading of finished products and improving production efficiency.

[0010] Furthermore, the first and second detection components employ similar structural arrangements. The first detection component includes a first detection bracket, on which a detection sensor is adjustably mounted. These detection components can precisely detect the assembly position, size, and shape of parts by adjusting the position and parameters of the detection sensors according to different needs during the assembly process. For example, they can detect whether the position of the assembled magnetic core is accurate, or the coaxiality of the assembled shaft, allowing for timely detection and adjustment of problems during assembly, effectively improving the product qualification rate.

[0011] Furthermore, the automated assembly line for new energy epoxy high-voltage DC contactors also includes a first transport component and a qualified product conveying component located on one side of the turntable mechanism. The qualified product conveying component is equipped with a demagnetizing coil assembly. The first transport component can be used to transport parts or semi-finished products between different workstations on the assembly line. The qualified product conveying component is used to transport qualified finished products to subsequent packaging or storage stages. The demagnetizing coil assembly can demagnetize the finished products, eliminating the magnetism generated during processing and ensuring stable product performance.

[0044] First, the entire automated assembly line for new energy epoxy high-voltage DC contactors was installed and debugged to ensure that all equipment, including the end cap assembly machine, moving core assembly machine, moving contact assembly machine, stationary arc extinguishing cover feeder, coil assembly machine, mechanical parameter testing machine, metal shell assembly and electrical testing machine, and shell assembly machine, were securely installed and that the wiring was correct and fault-free. The integrity and flexibility of the moving core assembly machine's moving core assembly frame, turntable mechanism, and transport fixture were checked to ensure smooth rotation of the turntable mechanism and that the transport fixture was securely mounted and accurately positioned on the turntable mechanism. The core assembly device was then debugged. The core vibration feeder was started, and the core blocking component was checked to ensure it could properly control core output. The stroke and speed of the lateral and vertical movement components for core transport were adjusted to ensure that the core gripping finger cylinder could accurately grip the core and place it in the designated position on the transport fixture. Debug the shaft assembly device, start the shaft vibration feeder, check the material distribution effect of the shaft distribution mechanism, calibrate the detection accuracy of the shaft length detection component, and adjust the motion parameters of the shaft feeding and handling robot and the shaft direction adjustment mechanism to ensure that the shaft can be transported and assembled according to the correct length and direction. Set up the snap ring assembly device, start the snap ring vibration feeder, check the material receiving jig, and debug the coordinated work of the clamping component, push spring component, and servo drive motor to ensure that the snap ring can be accurately installed in the corresponding position. Check the working status of the unloading movement XZ component and unloading finger cylinder of the finished product unloading device to ensure that they can smoothly remove the finished product from the transport jig and place it on the qualified product conveying component. Check the operation of the first transport component, qualified product conveying component, and demagnetizing coil component to ensure that each transport link is unobstructed and that the demagnetizing coil component is working properly. Calibrate the first detection component, the second detection component, and the snap ring vision detection component, and set the parameters of the detection sensors according to the assembly requirements to ensure accurate detection of the assembly quality of the parts.

[0045] During assembly: At the start of assembly, the magnetic core vibratory feeder of the magnetic core assembly device transports the magnetic core to the magnetic core blocking assembly. The magnetic core transport lateral movement assembly and the magnetic core transport vertical movement assembly work together to drive the magnetic core gripping finger cylinder to grip the magnetic core and place it on the transport fixture of the turntable mechanism. The turntable mechanism rotates, transporting the transport fixture containing the magnetic core to the first inspection component. The first inspection component inspects the assembly position and dimensions of the magnetic core. If the inspection is qualified, it continues to rotate to the shaft assembly device; if it is unqualified, an alarm is issued, and adjustment or rejection is carried out manually or by automated equipment. In the shaft assembly device, the shaft vibratory feeder outputs the shaft to the shaft distribution mechanism. After the shaft distribution mechanism distributes the shafts, the shaft loading and transporting robot transports the shafts to the shaft length detection component for length detection. Shafts that pass the inspection are then transported by the shaft loading and transporting robot to the shaft direction adjustment mechanism for direction adjustment. After adjustment, they are installed on the magnetic core assembly on the transport fixture. Next, the turntable mechanism transports the carrier fixture to the second inspection unit to inspect the assembly of the shaft, such as the coaxiality of the shaft and the magnetic core. After passing the inspection, it continues to rotate to the snap ring assembly device. In the snap ring assembly device, the snap ring vibratory feeder conveys the snap ring to the receiving fixture, the clamping component clamps the snap ring, and the servo drive motor drives the push spring component to install the snap ring into the designated position on the shaft. Then, the snap ring vision inspection component performs visual inspection of the snap ring assembly to ensure that the snap ring is installed correctly. Finally, the turntable mechanism transports the assembled finished product to the finished product unloading device. The unloading movement XZ component and the unloading finger cylinder remove the finished product from the carrier fixture and place it on the qualified product conveying component. The qualified product conveying component transports the finished product to the demagnetizing coil component for demagnetization treatment. The treated finished product can then proceed to the subsequent packaging or storage stages.
