Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle electronic controller assembly technology, and in particular relates to an automated flip assembly production line for new energy vehicle motor controllers. Background Technology

[0002] The motor controller is one of the core components of an electric vehicle. As the hub connecting the motor and battery, it directly determines the stability and responsiveness of the vehicle's power performance. The motor controller receives commands from the vehicle controller and draws electrical energy from the battery pack. Through a carefully tuned inverter, the motor controller can precisely output the current and voltage required to control the motor, thereby ensuring that the motor's speed and torque perfectly match the vehicle's needs.

[0003] Automotive electronic controllers consist of an electronic control housing and components assembled on its front and back sides. The housings for new energy vehicles are often made of aluminum alloy, and their weight varies depending on the vehicle model, typically weighing tens of kilograms. The upper and lower surfaces of the electronic control housing are assembly surfaces. During the assembly process, after assembling the corresponding components on one assembly surface of the electronic control housing, the housing is rotated 180° to assemble the components on the other assembly surface.

[0004] In existing technologies, the flipping of the electronic control housing is achieved manually.

[0005] The shortcomings of the existing technology are that the heavy weight of the electronic control housing makes manual flipping labor-intensive and poses safety hazards. Furthermore, since the electronic control housing is the carrier of precision control devices, even the slightest collision is not allowed during the flipping process, which further increases the difficulty of flipping.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The following is in conjunction with the appendix Figures 1 to 10 The automated rotating assembly line for the new energy vehicle motor controller of this utility model will be further described.

[0024] Please refer to this carefully. Figures 4 to 6 and Figure 9 This utility model discloses an automated rotating assembly production line for a new energy vehicle motor controller, used to achieve the rotation of the motor controller housing 100. The upper and lower surfaces of the motor controller housing 100 are respectively the second set of mating surfaces 101 and the first set of mating surfaces 102. The automated rotating assembly production line for the new energy vehicle motor controller includes: a material conveying line 1, a rotating machine 2 located on one side of the material conveying line 1, a multi-station transfer trolley 3 movably arranged, and a first tray 4 located on the material conveying line 1 and used to support the second set of mating surfaces 101. The rotating machine 2 includes: an operating platform 21, a protective cover 22 covering the upper part of the operating platform 21, rotating units 23 respectively located on both sides of the upper part of the operating platform 21, and a material unloading station 24. The material unloading station 24 is located inside the protective cover 22, and the rotating units 23 are also installed on the protective cover 22. Inside the material conveying line 1, a waiting station 111 is provided directly opposite the flipping unit 23. The waiting station 111 and the unloading station 24 are located on both sides of the flipping unit 23. The automated flipping assembly production line for new energy vehicle motor controllers also includes a second tray 5 that can flow between the unloading station 24 and the multi-station transfer trolley 3 and is used to support the first set of matching surfaces 102. The flipping unit 23 is used to rotate and extend the protective cover 22, clamp the electrical control housing 100 located on the first tray 4 from the waiting station 111 to the opposite sides, and then rotate in the opposite direction to retract into the protective cover 22, and place the flipped electrical control housing 100 on the second tray 5 of the unloading station 24. The multi-station transfer trolley 3 is used to transfer the second tray 5 and the electrical control housing 100 from the unloading station 24 to the next station as a whole.

[0025] In this embodiment, the material conveyor line 1 is fixedly installed as the initial conveying carrier for the electrical control housing 100, used to transport the electrical control housing 100 to be flipped to the designated working position. The flipping machine 2 is fixedly installed on one side of the material conveyor line 1 and is the core execution component for the flipping operation of the electrical control housing 100. The multi-station transfer trolley 3 is used to receive the flipped electrical control housing 100 and realize its transfer to the subsequent station. The first pallet 4 is placed on the conveying path of the material conveyor line 1, and its structure is adapted to the second set of mating surfaces 101 of the electrical control housing 100, used to stably support the electrical control housing 100 to be flipped (the support surface is the second set of mating surfaces 101). The second pallet 5 can flow bidirectionally between the unloading station 24 of the flipping machine 2 and the multi-station transfer trolley 3, and its structure is adapted to the first set of mating surfaces 102 of the electrical control housing 100, used to receive the flipped electrical control housing 100 (the support surface is the first set of mating surfaces 102).

[0026] Regarding the tilting machine 2: The operating platform 21 serves as the mounting base for all functional components of the tilting machine 2, providing a stable working support surface. The protective cover 22 is installed over the upper area of ​​the operating platform 21 to ensure safety during the tilting operation, while also providing dust protection. The tilting unit 23 is the core actuator, installed inside the protective cover 22, and has rotation and telescopic functions to achieve the clamping and tilting operation of the electrical control housing 100. The unloading station 24 is located inside the protective cover 22 and works in conjunction with the tilting unit 23 to place the second tray 5 to receive the tilted electrical control housing 100.

[0027] On the material conveyor line 1, a waiting station 111 is set up directly opposite the flipping unit 23. This station is used to temporarily store the electrical control housing 100, which is supported by the first pallet 4 and is awaiting flipping. The waiting station 111 and the unloading station 24 are located on both sides of the flipping unit 23, forming a straight operation path of "awaiting flipping - flipping execution - receiving after flipping", ensuring a smooth operation process.

[0028] The following describes the usage process of this utility model. The electrical control housing 100, assembled with the first set of mating surfaces 102, is supported by the first tray 4 (the supporting surface is the second set of mating surfaces 101). It moves along the material conveyor line 1 with the first tray 4 and eventually reaches the waiting station 111 for temporary storage. The flipping unit 23 is activated, first rotating and extending the protective cover 22 to the waiting station 111 to stably clamp the electrical control housing 100 on the opposite sides of the first tray 4. After clamping, the flipping unit 23 rotates in the opposite direction and retracts into the protective cover 22, simultaneously causing the electrical control housing 100 to complete a 180° flip. After the flipping unit 23 completes the flipping, it precisely places the electrical control housing 100 onto the second tray 5 at the unloading station 24 (at this time, the second tray 5 supports the first set of mating surfaces 102 of the electrical control housing 100). The second pallet 5, carrying the flipped electrical control housing 100, is transferred from the unloading station 24 to the multi-station transfer trolley 3. The multi-station transfer trolley 3 starts and transfers the second pallet 5 and the electrical control housing 100 as a whole to the next production station, completing a single flipping operation cycle.

[0029] Compared with existing technologies, this utility model provides an overall solution for realizing the flipping of the electrical control housing 100. The various components work together to achieve the automatic conveying, flipping, and transfer functions of the electrical control housing, effectively solving the problems of high labor intensity and easy damage to workpieces during manual operation, and improving operational safety. Furthermore, when the flipping unit 23 is working, most of its working area is located within the protective cover 22, further ensuring operational safety; when the flipping unit 23 rotates out of the protective cover 22 to pick up materials, it is also located above the waiting station 111—this area is a preset working area with relatively high safety. Therefore, this utility model has high safety, a high degree of overall automation, and is safe and reliable.

[0030] Please refer to this carefully. Figures 4 to 6 According to a specific embodiment of this utility model, the flipping unit 23 includes a motor reducer assembly 231, which includes an output rotating shaft 2311. The flipping unit 23 also includes a first clamping arm unit 232 and a second clamping arm unit 233 respectively fixed to both ends of the output rotating shaft 2311. A first retractable clamping block 2321 and a second retractable clamping block 2331 are respectively provided on opposite sides of the first clamping arm unit 232 and the second clamping arm unit 233. The flipping unit 23 also includes a lifting drive 234, a lifting guide unit 235, and an upper mounting plate 236 and a lower mounting plate 237 arranged vertically. The operating platform 21 is located on the upper mounting plate 236 and the lower mounting plate 237. Between plates 237; the motor reducer assembly 231 is mounted on the upper mounting plate 236 and the lower part of the motor reducer assembly 231 passes through the lower mounting plate 237; the lower part of the lifting drive 234 is mounted on the lower mounting plate 237 and the upper part of the lifting drive 234 is hinged to the lower part of the upper mounting plate 236; the lifting guide unit 235 includes: an upper guide sleeve 2351, a lower guide sleeve 2352 and a guide post 2353. The upper guide sleeve 2351 is fixedly mounted above the operating platform 21, the lower guide sleeve 2352 is fixedly mounted above the lower mounting plate 237, the upper part of the guide post 2353 is fixed below the upper mounting plate 236, and the lower part of the guide post 2353 slides through both the upper guide sleeve 2351 and the lower guide sleeve 2352.

[0031] In this embodiment, the motor reducer assembly 231 is a combination of a motor, a reducer, and an output rotating shaft 2311. The motor reducer assembly 231 in this embodiment has a dual-head output structure; the output rotating shaft 2311 rotates to drive the first clamping arm unit 232 and the second clamping arm unit 233 to rotate synchronously. Both the first retractable clamping block 2321 and the second retractable clamping block 2331 are retractable structures. In specific implementations, a telescopic cylinder can be used to extend and retract the first retractable clamping block 2321 and the second retractable clamping block 2331 to clamp and release the workpiece.

[0032] The lifting drive 234 can drive the overall lifting of the clamping arm unit (first clamping arm unit 232 and second clamping arm unit 233). This design can compensate for the height difference before and after the electronic control housing 100 is flipped, and can also expand the applicability of the automated flipping assembly production line of this utility model.

[0033] Specifically, when the first retractable clamping block 2321 and the second retractable clamping block 2331 clamp the workpiece, the first tray 4 and the second tray 5 located on both sides of the clamping arm unit are at the same height. However, in the height direction, there is a height difference between the center of the clamping blocks (first retractable clamping block 2321 and second retractable clamping block 2331) and the center of the workpiece. Using the structure of this embodiment, after the clamping arm unit rotates 180°, the height of the driving clamping arm unit is adjusted by the lifting unit to compensate for the height difference between the front and rear of the lower surface of the workpiece, ensuring that the second tray 5 precisely catches the workpiece. Furthermore, since the clamping arm unit is height-adjustable, it can adapt to material conveying lines with different heights, thus having a wider range of applications.

[0034] In this embodiment, the lower part of the lifting drive 234 is fixedly installed on the lower mounting plate 237, while its upper part is connected to the lower part of the upper mounting plate 236 by a hinge, forming a flexible transmission connection structure. The lifting drive 234 is hinged to the upper mounting plate 236. This structure, together with the lifting guide unit 235, forms a hinged and linear sliding combination structure for linear pushing scenarios.

[0035] This structure ensures the accuracy of the linear drive 234 in pushing the upper mounting plate 236, while avoiding structural damage or jamming caused by deviation or off-center load in practical applications when the linear drive is rigidly connected to the upper mounting plate 236, ultimately achieving a stable and reliable linear drive.

[0036] According to a specific embodiment of this utility model, there are two lifting drives 234, which are symmetrically arranged on both sides of the motor reducer assembly 231; there are four lifting guide units 235, which are divided into two groups of two, and are respectively installed between the motor reducer assembly 231 and the two lifting drives 234; the unloading station 24 is located on the operating platform 21, and the tilting machine 2 also includes a screw-out limit spring buffer limit head 30 and a screw-in limit spring buffer limit head 31 located on both sides of the output rotating shaft 2311; the screw-out limit spring buffer limit head 30 and the screw-in limit spring buffer limit head 31 are respectively .... The head 30 is installed on the operating platform 21, and there are two screw-out limit spring buffer limit heads 30, and the two screw-out limit spring buffer limit heads 30 are set one-to-one with the first clamping arm unit 232 and the second clamping arm unit 233; the screw-in limit spring buffer limit head 031 is installed on the operating platform 21, and there are two screw-in limit spring buffer limit heads 031, and the two screw-in limit spring buffer limit heads 031 are set one-to-one with the first clamping arm unit 232 and the second clamping arm unit 233, and the screw-in limit spring buffer limit head 031 is located between the unloading station 24 and the output rotating shaft 2311.

[0037] In this embodiment, two lifting drives 234 located on both sides of the motor reducer assembly 231 jointly drive the upper mounting plate 236 to rise and fall, which helps to balance the force and provide sufficient driving force. Four lifting guide units 235 are used to provide symmetrical guiding function, which helps to ensure the smoothness of the upper mounting plate 236 rising and falling. The screw-out limit spring buffer limit head 30 and the screw-in limit spring buffer limit head 031 provide buffering and mechanical limit for the screw-in and screw-out operations of the clamping arm units (first clamping arm unit 232 and second clamping arm unit 233), respectively, further improving the safety and reliability of the operation.

[0038] According to a specific embodiment of this utility model, the first clamping arm unit 232 and the second clamping arm unit 233 are symmetrical to each other. The flipping unit 23 further includes a reinforcing plate 238 that is fixedly connected to the first clamping arm unit 232 and the second clamping arm unit 233. The first clamping arm unit 232 further includes: a first fixed arm 2322, a first extended arm 2323, a first cylinder 2324, and a first clamping guide unit 2325. One end of the first fixed arm 2322 is connected to the output rotating shaft 2311, and the other end of the first fixed arm 2322 overlaps and is fixedly connected to one end of the first extended arm 2323, and the overlap length between the two is adjustable. The first telescopic clamping block 2 321 and the first cylinder 2324 are respectively installed on both sides of the first extension arm 2323. The first cylinder 2324 is used to drive the first telescopic clamping block 2321 to extend and retract. There are two sets of first clamping guide units 2325, and the two sets of first clamping guide units 2325 are respectively located on both sides of the first cylinder 2324. The first clamping guide unit 2325 includes a first guide sleeve 23251 and a first guide shaft 23252 slidably connected in the first guide sleeve 23251. The first guide sleeve 23251 is fixed to the outside of the first extension arm 2323, and the first guide shaft 23252 passes through the first extension arm 2323 and is fixedly connected to the first telescopic clamping block 2321.

[0039] In this embodiment, both the first fixed arm 2322 and the first extended arm 2323 are provided with connecting holes, and the overlap length between them can be adjusted by inserting connecting bolts into different connecting holes. This adjustable overlap length design improves assembly flexibility and installation accuracy. The first retractable clamping block 2321 is driven to extend and retract by the first cylinder 2324, and is balanced and guided on both sides by two sets of first clamping guide units 2325. This improves the accuracy and stability of the extension and retraction of the first retractable clamping block 2321, allowing it to move precisely to the side of the workpiece and clamp it securely. This further enhances the accuracy and safety of the operation.

[0040] It should be noted that this embodiment specifically describes the structure of the first clamping arm unit 232. Since the first clamping arm unit 232 and the second clamping arm unit 233 are symmetrical structures, the structure of the second clamping arm unit 233 can be referenced to that of the first clamping arm unit 232. The reinforcing plate 238 is used to increase the stability of the connection between the first clamping arm unit 232 and the second clamping arm unit 233.

[0041] According to a specific embodiment of this utility model, a small mounting plate 25 is installed on the operating platform 21. A tray guide plate 26 is symmetrically arranged on both sides of the small mounting plate 25. The small mounting plate 25 is also provided with a flow strip 27, and the flow strip 27 is located between the two tray guide plates 26. A recessed mounting notch 251 is provided on the side of the small mounting plate 25 away from the output rotation shaft 2311. The tilting machine 2 also includes a backstop 28. The lower part of the backstop 28 is fixed on the operating platform 21, and the upper part of the backstop 28 extends into the mounting notch 251. A protruding L-shaped limiting block 29 is provided on the upper part of the side of the small mounting plate 25 near the output rotation shaft 2311. The two tray guide plates 26, the backstop 28, and the L-shaped limiting block 29 together form the unloading station 24.

[0042] In this embodiment, the small mounting plate 25 serves as the mounting base, facilitating the overall installation of the components located on it onto the operating platform 21. The pallet guide plate 26 guides the left and right sides of the second pallet 5. The flow strip 27 provides rolling support to improve the smoothness of the second pallet 5 sliding in and out. After the second pallet 5 smoothly slides into the unloading station 24, the L-shaped limiting block 29 limits the front end of the second pallet 5, and the anti-reverse device 28 pops up to prevent the second pallet 5 from retracting. The anti-reverse device 28 can be a directly purchased component. Installing the anti-reverse device 28 using the recessed mounting notch 251 further improves the compactness of the device.

[0043] As can be seen from the above, this embodiment provides a simple, compact, and highly practical structure for the unloading station 24.

[0044] Please refer to this carefully. Figure 10 According to a specific embodiment of the present invention, the second tray 5 includes: a second tray base plate 51 that is rectangular in shape, four second support columns 52 that are fixed to the four upper corners of the second tray base plate 51, a first tray side locking block 53 and a second tray side locking block 54 that are located on both sides of the upper part of the second tray base plate 51 and are symmetrical to each other. The first tray side locking block 53 is provided with a recessed locking groove 531 on the side away from the second tray side locking block 54.

[0045] In this embodiment, four second support columns 52 are used to jointly support the workpiece. Specifically, the four second support columns 52 can have the same shape, partially the same shape, or be completely different to adapt to the shape of the workpiece and ensure stable support for the workpiece located on it. The second tray base plate 51 provides a fixed installation foundation for the second support columns 52. The second tray base plate 51 is provided with locking blocks (first tray side locking block 53 and second tray side locking block 54) with locking grooves 531, which facilitates the locking and fixing of the second tray 5 in subsequent transfer processes, ensuring the safety and stability of the transfer process.

[0046] Please refer to this carefully. Figures 7 to 8 According to a specific embodiment of this utility model, the multi-station transfer trolley 3 includes a rectangular support plate 31, and n rectangular transfer stations 32 are arranged sequentially along the length of the support plate 31, where n≥2 (n is a positive integer). Each transfer station 32 has a width block 33 at each of its four corners, and each transfer station 32 has a spring pin 34 for inserting into the snap-fit ​​slot 531 on each side of its width direction. The support plate 31 has a flip-up continuous baffle 35 and a length block 36 on each side of its length direction. Each transfer station 32 is equipped with at least one length block 36, and all transfer stations 32 share a flip-up continuous baffle 35.

[0047] In this embodiment, each transfer station 32 is used to carry a second pallet 5 or a second pallet 5 carrying a workpiece. A width-direction stop 33 provides a limit and obstruction in the width direction of the second pallet 5, and a length-direction stop 36 guides the second pallet 5 in one length direction. A flip-up continuous stop 35 flips downwards to open, without affecting the second pallet 5 sliding into or out of the transfer station 32. When the flip-up continuous stop 35 flips upwards and is fixed, it can limit the other length direction of all second pallets 5 located within the transfer station 32. When the second pallet 5 is located in the transfer station 32, a spring pin 34 inserts into the locking groove 531 to limit the second pallet 5. Pulling the spring pin 34 and rotating it at a certain angle ensures that the spring pin 34 is disengaged from the locking groove 531, without affecting the free sliding out of the second pallet 5. The spring pin 34 can be a directly purchased component.

[0048] The multi-station transfer trolley 3 is used to transfer the second pallet 5 and the electrical control housing 100 located on the second pallet 5 from the unloading station 24 to the next station. In practice, to improve efficiency, the multi-station transfer trolley 3 can also be used as a loading tool for the second pallet 5. In this case, an empty second pallet 5 is installed at each transfer station 32. The multi-station transfer trolley 3 is pushed to one side of the unloading station 24, aligning the unloading station 24 with one of the transfer stations 32. Using an operator or an external robotic arm, one of the second pallets 5 on the multi-station transfer trolley 3 is pushed to the unloading station 24, thus adding an empty transfer station 32 to the multi-station transfer trolley 3. After the second pallet 5 receives a flipped workpiece, the operator or external robotic arm transfers the second pallet 5 along with the workpiece onto the empty transfer station 32. The multi-station transfer trolley 3 is moved a certain distance to ensure that the next transfer station 32 is aligned with the unloading station 24. Repeat the above steps until the second pallet 5 above the multi-station transfer trolley 3 is replaced with a pallet loaded with workpieces. Then flip the flip-up continuous baffle 35 in the multi-station transfer trolley 3 upward and fix it. The flip-up continuous baffle 35 blocks all the second pallets 5, which can further provide lateral restraint for the second pallets 5 and improve the safety of the transfer process.

[0049] The multi-station transfer trolley 3 has multiple transfer stations 32, which can transfer multiple empty second pallets 5 or second pallets 5 carrying the electrical control housing 100 at one time. In this embodiment, n=3, so three second pallets 5 can be loaded at one time, thereby improving the transfer efficiency.

[0050] According to a specific embodiment of this utility model, the multi-station transfer trolley 3 further includes a pin 37 and a handle 38. The pin 37 is installed on one side of the handle 38. The cross-sectional outer contour of the flip-up continuous baffle 35 is rectangular. The handle 38 is welded from a metal rod with a rectangular cross-section. One outer side of the flip-up continuous baffle 35 is hinged to the outside of the support plate 31 via a hinge. The flip-up continuous baffle 35 includes an upward limiting state. When the flip-up continuous baffle 35 is in the upward limiting state, the handle 38 is in surface contact with one side of the flip-up continuous baffle 35, and the pin 37 extends out and abuts against the opposite side of the flip-up continuous baffle 35.

[0051] In practice, the handle 38 is welded from a square tube. This structure serves two purposes: firstly, it provides a mounting surface for the pin 37; secondly, when the flip-up continuous baffle 35 is in the upward-limited position, the handle 38 contacts the flip-up continuous baffle 35 face to face, and the pin 37 limits the other side, thus preventing the flip-up continuous baffle 35 from flipping over, ensuring the stability of the flip-up continuous baffle 35's position, and improving the effect of blocking the second tray 5.

[0052] According to a specific embodiment of this utility model, the material conveying line 1 includes a double-layer line and a first elevator 13 and a second elevator 14 located at both ends of the double-layer line. The double-layer line includes an upper line 11 and a lower line 12 arranged vertically. The first elevator 13, the upper line 11, the second elevator 14, and the lower line 12 together form a closed circular conveying track. The waiting station 111 is located on the upper line 11 directly opposite the flipping unit 23. A lifting mechanism 15 is provided below the waiting station 111.

[0053] In this embodiment, the upper conveyor 11 moves in the direction of the production line flow. During use, the electrical control housing 100, which has completed the assembly of the first set of mating surfaces 102 and is to be flipped, is supported by the first tray 4. As the first tray 4 moves on the upper conveyor 11, the lifting mechanism 15 lifts the first tray 4, placing the electrical control housing 100 at the waiting station 111. After the flipping machine 2 removes the workpiece, the lifting mechanism 15 descends, and the empty first tray 4 returns to the starting position of the production line via the material conveyor 1, facilitating rapid and continuous workpiece loading.

[0054] According to a specific embodiment of the present invention, the operating platform 21 and the support plate 31 are at the same height; the protective cover 22 is provided with a tray inlet / outlet 221 on the side away from the material conveying line 1, and a pair of safety light curtains 032 are provided on the two side walls of the tray inlet / outlet 221.

[0055] In this embodiment, the operating platform 21 is planar, which facilitates the assembly and observation of the various components of the tilting machine 2. The operating platform 21 and the support plate 31 are at the same height, and after docking, there is no height difference between them, which facilitates the smooth entry and exit of the second tray 5. A safety light curtain 032 is installed at the tray inlet / outlet 221. Combined with the control system, the tilting unit 23 can stop operating when an object is detected entering the tray inlet / outlet 221, thereby improving the safety of the operation and ensuring the safety of the operators.
