Description

Flat wire motor stator copper wire milling equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 10, 2024, with application number 202410038430.6, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of processing equipment, for example, to a flat wire motor stator copper wire milling processing equipment. Background Art

[0003] With the continued boom in the new energy vehicle market, electric drive systems, as one of the core components of new energy vehicles, are trending towards lightweighting, high efficiency, miniaturization, and low cost. The primary technical approaches to achieving this are electric drive system integration and flattening of motors. Using flat wire significantly increases the slot fill factor (the proportion of space occupied by a coil after placement) because round wires have gaps between them, while flat wires are more compact. In simple terms, a higher slot fill factor means more wires in the coil, resulting in a stronger magnetic field and, consequently, greater motor power. Clearly, market demand for flat wire motors is poised for explosive growth. This poses a challenge to selecting faster, more efficient, and lower-cost automated assembly equipment for flat wire motors.

[0004] As a precursor to laser welding, the flatness of the copper wire in the flat-wire motor stator affects the consistency of laser welding and the fullness of the weld joint. Related technologies often use integral punching to flatten the ends of the copper wire, and there is no milling equipment specifically designed for this process. While punching equipment can meet the requirements of laser welding, it relies heavily on cutting tools, and the quality of the flattening tools determines the quality of the copper wire's punched end face. Furthermore, each slot in the flat-wire motor stator requires a flattening tool, so a single device needs to be equipped with dozens of tools, each of which needs to be customized and purchased based on the copper wire's specifications, increasing both the equipment's procurement and maintenance costs. Furthermore, due to the large number of tools, any wear on a single tool can affect the equipment's operation, resulting in a low fault tolerance and increased maintenance frequency. Summary of the Invention

[0005] The present application provides a flat wire motor stator copper wire milling processing equipment, which can be combined into different configurations through flexible configuration between multiple modules according to the beat and production capacity requirements of the production line, and has the advantages of high speed, high efficiency, high flexibility, high stability and low cost. It has a structural design and milling process that are particularly suitable for the milling processing of flat wire motor stator copper wire, a dust collection system that can prevent copper chip contamination during the processing process, a fast and precisely positioned fixture, flexible automatic loading and unloading configuration options, configuration options that are compatible with multiple control systems, and a tool changing system that can automatically change tools. The equipment has a compact structure, a small footprint, is easy to install and debug, simple to maintain, and has low operating costs.

DETAILED DESCRIPTION

[0019] The following will describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Example 1

[0021] As shown in Figures 1-8, the present invention discloses a flat-wire motor stator copper wire milling machine, employing a modular, standardized, and serialized design approach. The main structure of the machine is conceptually divided into a bed component and a main body component, both of which are modularly developed. The bed component functions as a spindle mounting assembly, primarily consisting of a bed 21, a spindle slide 22, and a spindle 25. The main body component functions as a workpiece and fixture mounting unit, primarily consisting of a crossbeam 31, a saddle 32, a ram 33, and a positioning and clamping device.

[0022] The bed parts and main body parts are functionally spliced ​​according to the production line rhythm and capacity requirements, and are equipped with a tool changing system and a dust collection device 5 with a certain number of tool magazines 7. A chip conveyor 4 is connected to the bottom for collecting copper chips, completing the overall configuration of the machine tool.

[0023] In terms of the overall machine tool function, the present application realizes a series of multiple machine tool configurations. In terms of the workstation, there are two types: single-station and double-station; in terms of the number of spindles 25, it can be divided into single-spindle and double-spindle; in terms of the tool magazine 7 configuration function, it can be divided into single-tool magazine 7, double-tool magazine 7 and no-tool magazine 7; in terms of the automation interface, it can be divided into robot loading and unloading and truss manipulator loading and unloading; multi-station (greater than or equal to 3) and multi-spindle (greater than or equal to 3) configurations can also be used to meet special production capacity requirements.

[0024] As shown in Figure 1, the workpiece clamping unit 1 employed in this application is suitable for flexible automated assembly lines and comprises a fixture body 12, a clamping power system 14, and a fixture positioning mechanism 13. This workpiece clamping unit 1 can individually clamp each pair of copper wire terminals without the need for additional power. The workpiece and fixture are loaded and unloaded as a whole, and are positioned and clamped by the fixture positioning mechanism 13. The workpiece clamping unit 1, used for positioning and clamping the stator of a flat wire motor, achieves high-precision positioning and maintains the clamped state through a two-pin positioning method on one side.

[0025] As shown in Figure 2-3, the bed components adopt a modular design. The spindle slide 22 is arranged on the bed 21 to realize X-axis movement. The spindles 25 (spindle one 251 and spindle two 252) are fixed to the spindle slide 22 through spindle adapters 23 (spindle adapter one 231 and spindle adapter two 232). Multiple spindles 25 can be fixed in the same way. The bed 21 adopts a large inclination angle design to facilitate chip discharge and collection. The modularly designed horizontal slide structure realizes the inverted installation of the processing spindle 25 (mechanical spindle or electric spindle) or the power head. The number of processing spindles 25 is determined according to the line beat and production capacity to realize single-spindle or multi-spindle processing; the modularly designed bed components determine the corresponding installation interface structure on both sides of the bed 21 according to the automatic loading and unloading method.

[0026] As shown in Figures 4-5, the main components utilize a modular design. The saddle 32 and ram 33 are mounted on a crossbeam 31, enabling workpiece movement in the Y and Z axes. The ram 33 is equipped with a positioning and clamping device for the workpiece clamping unit 1, ensuring precise positioning and secure clamping of the fixture. With this modular design, the crossbeam 31 can accommodate varying numbers of workpiece clamping units 1, enabling single-station or multi-station machining and improving production line efficiency.

[0027] According to the serialized configuration scheme, this equipment can be combined into the following configurations: single-spindle single-station flat wire motor stator copper wire milling equipment (as shown in Figure 6), dual-spindle dual-station flat wire motor stator copper wire milling equipment (as shown in Figure 7), dual-spindle single-station flat wire motor stator copper wire milling equipment (as shown in Figure 8). For other multi-station and multi-spindle configurations, the modules on the crossbeam 31 assembly and the spindle modules on the bed 21 can be added accordingly.

[0028] The above series of equipment are configured according to the production line rhythm and production capacity.

[0029] When dual-spindle processing is selected, two working modes can be configured: single-station or dual-station (as shown in Figures 7-8). When processing in single-station processing mode, the two spindles 25 are respectively equipped with slot milling cutters and disc milling cutters to realize the two processes of cutting and finishing the stator copper wire. Each spindle 25 only performs one process, so there is no need to change the tool. Therefore, there is no need to configure an additional tool magazine 7 for tool change, which can avoid the time consumption of tool change, greatly reduce the auxiliary time, and thus improve the production cycle; when processing in dual-station processing mode, each spindle 25 corresponds to a station, and needs to complete the two processes of copper wire cutting and end finishing milling respectively. Therefore, the spindle module needs to be configured with a tool magazine 7 for tool change, so that one machine tool can process two workpieces at the same time, thereby greatly improving processing efficiency and production capacity, and reducing floor space and equipment investment.

[0030] When a single spindle is selected, a single-station configuration can be selected for processing (Figure 6). This is the most basic configuration of the equipment, and other configurations are expanded and reconfigured based on this. Alternatively, when a single spindle is selected, a dual-station configuration can be selected for processing. This can reduce the waiting time for loading and unloading during single-station processing. However, at the same cost, the dual-spindle single-station configuration has a faster cycle time, higher efficiency, and greater production capacity, so this configuration is not recommended.

[0031] Based on the production line automation configuration, robots or truss manipulators can be selected for loading and unloading according to different beat requirements and line planning. For single-station processing (Figures 6 and 8), when robot loading and unloading is selected, the robot station can be installed at the fixed installation interface position on the left or right side of the bed 21, so that it can be put into place after one installation and debugging, eliminating the secondary installation time and greatly shortening the product delivery cycle; when truss manipulators are selected for loading and unloading, the truss is installed at the fixed installation interface position on the upper side of the bed 21 to complete the splicing of the truss. For double-station processing (as shown in Figure 7), it is recommended to select robot loading and unloading, and the robot station is installed on the left and right sides of the bed 21 at the same time to achieve separate and synchronous loading and unloading of two workpieces, avoiding the waiting time generated by the truss manipulator when loading and unloading, shortening the loading and unloading time, and improving the production line beat. The above-mentioned automation interfaces are all configured on the bed 21. The bed 21 adopts a modular design, and the corresponding bed components can be manufactured according to the configuration requirements.

[0032] Based on the production capacity requirements of the production line, you can choose between single-station and dual-station working modes. When the dual-station processing mode is selected (Figure 7), there are two sets of saddles 32 (saddle 1 321 and saddle 2 322) and rams 33 (saddle 1 and ram 2) structures on the crossbeam 31, which can be controlled independently. Each set of saddles 32 and rams 33 is equipped with a set of workpiece clamping units 1 (workpiece clamping unit 1 15 and workpiece clamping unit 2 16) and a set of dust collection devices 5. The dust collection devices 5 (dust collection devices 1 51 and dust collection devices 2 52) are fixed on the ram 33 and move up and down with the ram 33. Before the spindle 25 is processed, the dust collection device 5 moves downward with the ram 33 and fits into the spindle sealing plate 24 (spindle sealing plate 1 241 and spindle sealing plate 242), forming a closed processing area, while enclosing the tool 6 (tool 1 61 and tool 2 62) inside, and then processing is carried out. After the machining is completed, the dust collecting device 5 moves upward with the ram 33, and the sealed area is opened to drive the remaining chips out of the spindle 25 (spindle 1 251 and spindle 2 252). The independent negative pressure dust collecting device 5 can prevent copper chips and copper powder from contaminating the motor.

[0033] For tool magazine 7 (tool magazine 1 71 and tool magazine 2 72), you can choose a tool magazine 7 with a robot tool change or a tool magazine 7 without a robot according to the additional functions of the spindle 25. When the spindle 25 does not have an additional auxiliary axis movement function, after moving the spindle 25 to a fixed tool change point, select the tool magazine 7 with a robot tool change to perform the tool change operation. When the spindle 25 has an additional movement function and can move along the axis of the spindle 25, you can choose a tool magazine 7 without a robot and fix the tool magazine 7 on both sides of the bed 21 along the movement direction of the spindle module, and perform the tool change operation through the movement of the spindle 25. Select a tool changing system according to the configuration requirements to improve the production line beat.

[0034] In addition, for each configuration of equipment, a chip conveyor 4 is configured to collect chips. The chip conveyor 4 configured on the lower side of the bed 21 is used to collect copper chips.

[0035] The present application relates to a modular design and serialized structural configuration of a novel flat wire motor stator copper wire milling processing equipment, which realizes cutting processing by adopting one or more spindles 25 on the bed part; adopts a horizontal slide (spindle slide 22) on the bed part to realize the cutting feed and tool changing operation of the spindle 25 in the X direction; flexibly adopts one or more cross slides on the rear part of the bed part according to the wire body beat to realize the movement of the workpiece in the Y direction and the Z direction; adopts a positioning clamping device on the vertical slide to realize the rapid loading and unloading of the fixture and the workpiece as a whole; adopts a dust suction device 5 in the middle area between the spindle 25 and the workpiece to realize the cross cutting The copper powder generated during the cutting process is collected centrally; according to the line beat requirements, different numbers of tool changing systems are used on both sides of the bed 21 to achieve fast tool changing operations; different automation module interfaces are used on the bed 21 to realize robot loading and unloading and truss manipulator loading and unloading; by using a chip conveyor 4 at the bottom of the bed 21, the copper chips are collected centrally; dry machining is used to achieve green machining; side milling and face milling are used for machining; the structure and layout of the machining center are flexibly designed to perfectly meet the high-speed, high-efficiency, high-precision and large-scale processing requirements of the flat wire motor copper wire milling process.

[0036] The equipment adopts a standardized and modular design concept. The multiple components that make up the equipment, including the bed, main body, spindle 25, workpiece clamping unit 1, and other modules, all adopt a standardized and modular design concept. The multiple components have highly unified installation interfaces, which can be flexibly combined and assembled. Based on this modular design, multiple components can be mass-produced and assembled into equipment with different configurations by selecting modules. It is possible to choose single-spindle or dual-spindle modules, single-station or dual-station processing modules, and auxiliary mechanisms for robot loading and unloading or truss manipulator loading and unloading. For example, for very high production capacity requirements, multiple spindle modules and multiple processing stations can be configured.

[0037] The equipment is configurable, reconfigurable and scalable. Based on the modular design concept, it can flexibly select and match multiple sub-modules to assemble equipment with different configurations to meet the requirements of production line rhythm and production capacity; the equipment can be quickly transformed by replacing the corresponding component modules to meet the processing of motor stator copper wires of different specifications; the original equipment can be quickly expanded by adding workstations or adding spindles 25 to expand production capacity.

[0038] The structural design is based on the process requirements of flat wire motor stator copper wire processing. The flat wire motor is fixed with its head facing downward. This method can set the processing area below the motor so that the copper chips generated by processing fall directly due to gravity, effectively preventing the copper chips from entering the stator and contaminating the motor; in addition, the dust collection device 5 added to the milling area can collect the copper powder generated by milling.

[0039] In terms of processing characteristics, this is the first time that metal side milling has been applied to the processing of flat-wire motor copper wire. This is the first time that side milling and face milling solutions have been integrated into the processing of flat-wire motor stator copper wire. First, side milling is used to flatten the flat-wire motor stator copper wire with a slotting cutter. Then, face milling is used to finish mill the flattened copper wire end faces with a face milling cutter to meet the required dimensional tolerances and surface finish. The entire milling process uses two standard metal cutting tools, both of which are low-cost and easy to purchase. Customized special tools are also available to improve processing efficiency, accelerate production cycles, and achieve higher production capacity.

[0040] The structural design of the machine tool fully considers the expansion needs of the milling process. On the basis of fully considering the needs of the current process solutions for side milling and face milling, it can also easily switch to the processing technology of plunge milling and countersinking (milling).

[0041] The spindle is installed in an inverted manner with the nose of the spindle 25 facing upwards. During processing, the workpiece is located above the spindle 25, which is in line with the cutting process of flat wire motor stator copper wire processing. This can avoid the accumulation of copper chips generated by processing on the workpiece surface, thereby protecting the cleanliness of the workpiece.

[0042] The equipment is designed based on the concept of a machining center. It has the same drive system as a machining center, basic components with sufficient rigidity and a spindle 25 unit for rotary cutting. It can be adapted to the machining center controller, the tool changing system of the tool magazine 7 can be flexibly configured, and automatic control can be achieved through programming. Based on the above characteristics, the equipment has the characteristics of a traditional machining center rather than an unconventional special machine.

[0043] Compatible with a variety of control systems, this equipment is part of the flat-wire motor stator assembly line. It completes the entire cutting process through simple point-to-point motion and logic control. Therefore, industrial robot control software can be used to control the entire device. This device has the universality of automated assembly line control systems. Compared to traditional machining centers, this device avoids reliance on computerized numerical control (CNC) systems and reduces controller configuration requirements. Of course, it can also be controlled by relatively high-end CNC numerical control systems, such as the imported Siemens 828D or the domestically produced Huazhong CNC.

[0044] The fixture design is based on the milling process of the flat wire motor stator copper wire. The high-speed and low-feed milling process means that even if there is slight vibration during the processing, it will not affect the processing accuracy of the flat wire motor stator copper wire. This allows the flat wire motor fixture design to abandon the high rigidity, high positioning accuracy and high clamping force requirements of traditional fixtures, reducing the difficulty and cost of flat wire motor fixture design.

[0045] The equipment fully considers the compatibility with automatic loading and unloading. It can be conveniently equipped with truss manipulator loading and unloading and robot loading and unloading. It can also adopt manual loading and unloading at the front end or manual loading and unloading with the help of power assist system.

[0046] The workpiece can be circulated. The flat wire motor is pre-fixed on the clamping unit for transmission. The motor and fixture are directly loaded for processing as a whole. Therefore, it can be reasonably scheduled and circulated according to the completion status of each workstation, eliminating the waiting time for occupying a position, speeding up the flow of workpieces and improving the production efficiency of the production line.

[0047] This unit is a workpiece clamping unit used for clamping flat wire motor stators and overall loading and unloading. It is a special fixture for clamping flat wire motor stators. It fixes and clamps the flat wire motor stator through a clamping and holding system. It can use a one-side two-pin positioning method to achieve positioning and clamping after loading. To improve the efficiency of loading and unloading and speed up the flow of workpieces, a zero-point quick-change system can be used for positioning and clamping.

[0048] The dust suction device in the processing area is fixed to the slide 33 and moves with the slide 33, so that it fits with the end of the main shaft 25 to form a closed negative pressure processing area, which can effectively absorb the copper powder generated by the processing and protect the motor from pollution.

[0049] The modular design of the bed 21, the modular design of the bed parts and the coordinated design of the automation interface, the bed 21 is designed with a large angle slope to facilitate chip collection, the bed 21 is designed with automatic loading and unloading interface modules for connecting and fixing the robot station and the installation orientation can be flexibly selected, and the interface for truss fixed installation, eliminating the secondary development of the automation station in the later stage and saving development costs.

[0050] As a green processing method, dry milling is selected and a dust collection device 5 is configured to prevent the copper powder generated by the processing from being scattered into the air and causing harm to the human body and the environment. In addition, a chip conveyor 4 is separately configured to lift and collect the copper chips, making it easier to clean the copper chips.

[0051] The flexible tool magazine system allows for selection of tool changers with varying numbers of tool magazines 7, depending on the number of machining stations and spindles 25. Depending on the configuration of the spindle 25's axial auxiliary motion function, tool magazines 7 with or without robotic tool changers can be selected. Furthermore, tool magazines 7 can be equipped with a reserved tool position to keep tools 6 readily available, eliminating downtime associated with tool replacements.

[0052] Beautiful overall appearance design, simple structure and integrated machine tool outer protective cover can be easily set with automatic front door, automatic top door or manual front door to meet the needs of robot loading and unloading, truss manipulator loading and unloading or manual loading and unloading.

[0053] It should be noted that this application utilizes a traditional machine tool through optimization, modification, and configuration, integrating side and face milling to achieve the milling of copper wire for flat-wire motor stators. Therefore, this application is not limited to the equipment structure described in the preceding embodiments. Instead, it defines a milling solution for copper wire for flat-wire motor stators and integrates it with traditional machining center modules to form a new type of machining equipment. This equipment possesses the structure and characteristics of traditional machining while also taking into account the design and configuration that allows it to be integrated into the assembly line for flat-wire motor stators.

[0054] The structure of this application adopts a modular design concept. The various components of the equipment are split according to the modular concept. Multiple modules have a unified installation interface to achieve interchangeable installation of modules with different configurations.

[0055] The structure of this application adopts a serialized flexible configuration design, and the configuration modules can be flexibly selected according to the beat and production capacity of the production line to improve the flexibility of the line assembly.

[0056] The structure of this application adopts the design concept of the machining center, and replaces the punching processing method with the spindle milling processing method. It has the advantages of fast cutting speed and good surface quality, and has a simple structure, low investment cost and easy maintenance.

[0057] The structure of the present application adopts a high-speed and low-feed milling process, which reduces the impact of vibration generated during the machining process on the milling accuracy and improves the machining quality and stability.

[0058] The processing technology used in this application structure is compatible with two types of standard metal processing tools, does not require special customization, has low procurement costs, and has a long service life. It can also prepare tools in empty tool positions in the tool magazine, greatly shortening tool procurement and replacement time, reducing equipment downtime, and improving production line utilization.

[0059] This application has a compact structure and small footprint. It can flexibly choose automated solutions such as robot or truss manipulator loading and unloading. It is fixed through the installation interface on the bed module to achieve overall transportation, avoiding secondary disassembly and installation of the equipment, greatly shortening the delivery time of the production line and significantly reducing labor costs. Of course, manual loading and unloading solutions assisted by humans or other equipment can also be used.

[0060] The structure of this application adopts a structural design that fits the flat wire motor stator copper wire processing technology. The flat wire motor is installed upside down (copper wire terminals facing down) for processing, which can effectively prevent the chips generated during processing from entering the motor due to gravity. It is also equipped with a dust suction device to centrally collect the dust generated during the processing, effectively avoiding pollution and damage to the motor.

[0061] This application is simple to install, easy to debug, and convenient to maintain, which can greatly reduce the time for assembly and debugging as well as maintenance after shutdown, and greatly improve the utilization rate of the production line.

[0062] Example 2

[0063] From the perspective of overall structural layout, this application can be developed according to the machine tool structure of a gantry machining center, or according to the structure of a vertical machining center (Figures 9 to 11 are optional structures of the vertical machining center), and can also be improved on the basis of the framework of other vertical machining centers. The key lies in the arrangement of the spindle and the workpiece clamping unit, so that the equipment has the function of processing the copper wire of the flat wire motor stator.

[0064] The main difference between this embodiment and embodiment 1 is that, when unfolded according to the structure of a vertical machining center, the overall equipment eliminates the crossbeam module, and the bed module is a right-angled trapezoidal structure. The saddle 32 moves horizontally and longitudinally on the upper end surface of the bed 21, and the bed slide 8 moves on the inclined surface of the bed 21. The large-angle inclination design does not produce chip accumulation. The bed slide 81 and bed slide 82 in Figure 10 can be parallel mechanisms controlled by independent drive systems or serial mechanisms controlled by a single drive system; in Figure 11, saddle 1 91 and saddle 2 92 can be parallel mechanisms controlled by independent drive systems or serial mechanisms controlled by a single drive system. The above-mentioned bed slide 1 81 and bed slide 2 82 can be parallel mechanisms controlled by independent drive systems or serial mechanisms controlled by a single drive system.
