Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and in particular to a production bus for motor assembly and testing. Background Technology

[0002] As a core power component, electric motors are widely used in industrial equipment, home appliances, and new energy vehicles. Their manufacturing quality directly affects the performance and reliability of the final product. Traditional motor assembly lines often employ discrete production lines composed of multiple independent specialized machines, typically consisting of several independent workstations or machines. This presents the following technical challenges: First, quality inspection is delayed and isolated, failing to form an effective closed loop with the assembly process. Most existing assembly lines adopt a separate model of assembly first, testing later, with performance testing typically a separate process at the end of production. In this model, if a test fails, the defective product may have already completed all subsequent assembly, leading to high rework costs and difficult disassembly. More importantly, quality problems arising during assembly, such as improper screw torque or poor turbine cover engagement, cannot be detected and intercepted in time at this stage. The correlation between the cause of the problem and the process in which it occurred is severed, preventing real-time feedback and dynamic adjustment of process parameters between assembly and inspection, resulting in passive and inefficient quality control.

[0003] Secondly, the precision and reliability of key assembly processes at each independent workstation are highly dependent on human experience. The equipment has limited performance and lacks systematic support, which affects the accuracy of testing. These problems make it difficult to improve the first-pass yield of the entire line and make it highly dependent on the skills of the operators.

[0004] Therefore, there is an urgent need in this field for an automated motor production system that can integrate various assembly and testing processes, achieve flexible production, organic integration, and collaborative control, in order to overcome the above-mentioned shortcomings in the existing technology.

[0016] 1. This application constructs a closed-loop "assembly-testing" process, deeply integrating performance testing into the assembly process, and realizing online real-time quality monitoring. Through an automatic motor testing device, utilizing the cooperation of a floating, center-aligned insertion shaft and a perforated rotating plate, key performance parameters such as motor speed, direction of rotation, internal pressure, and power are detected in real-time and accurately under simulated load.

[0017] 2. This invention innovatively integrates an automatic motor testing device as a standard process unit within the production bus, placing it after critical assembly stages such as turbine cover and retaining ring assembly are completed. Each motor, after completing its staged assembly, can undergo performance testing at its current workstation for speed, direction, power, and internal pressure without needing to be taken offline. Only motors that pass the tests can proceed to the next cover installation and assembly process; if a test fails, an online alarm is immediately triggered and the process is blocked.

[0018] 3. Precise automation of core processes has been achieved, significantly reducing reliance on manpower and operational errors. Through a series of specialized devices, key processes that traditionally relied on skilled workers have been automated: the automatic screw adjustment device automatically locates and aligns with the screw groove, precisely adjusting and detecting the current, replacing manual adjustment by feel; the turbine cover assembly device automatically completes the reliable engagement of the eight-tooth shaft and the turbine cover through the coordinated action of pressing, lifting, and slow rotation; the automatic snap-fit ​​device uses a specially shaped guide shaft to guide and press the snap-fit, solving the problem of assembling small, elastic parts; and the automatic cover installation device has automatic hole recognition and anti-jump functions, ensuring the reliability of screw tightening. These devices work together to guarantee the consistency and high precision of the assembly process.

[0019] 4. A standardized logistics and positioning system enables efficient and flexible connection of multiple devices. The conveying assembly, consisting of slide rails and pallets, works in conjunction with the tenth cylinder and lifting plate of the lifting device at each workstation, providing a unified material interface for all device units. Motors to be assembled are precisely transported and positioned via pallets with contoured positioning grooves, allowing each device to operate on them quickly and accurately. This design allows for changes in product models on the production line, requiring only pallet replacement or adjustment, significantly improving the flexibility and changeover efficiency of the production line.

Detailed Implementation

[0022] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0023] A production bus for motor assembly and testing, such as Figures 1-34 As shown, a production bus for motor assembly and testing includes the following sequentially connected device units according to the motor assembly process flow: motor housing integration unit 1, automatic screw adjustment device 2, turbine cover assembly assembly device 3, automatic snap-fit ​​device 4, automatic motor testing device 5, automatic cover installation device 6, and automatic glue application device 7. like Figures 2-5 The automatic motor testing device 5 includes a fourth frame 51, a first cylinder 52, a first mounting plate 53, a bearing 54, a first connecting rod 55, a first connecting plate 56, a second connecting plate 57, a first sleeve 58, an insertion shaft 59, a first spring 510, a first power input socket 511, and a withstand voltage power detector 512. The first cylinders 52 are respectively arranged on both sides of the fourth frame 51. The first mounting plates 53 are all arranged on the first cylinders 52. The bearings 54 are all arranged on the first mounting plates 53. The first connecting rods 55 are arranged on the bearings 54. The second connecting plate 57 is arranged on the first connecting rods 55. The first sleeve 58 passes through the second connecting plate 57 and is mounted on the first connecting plate 56. The insertion shaft 59 is slidably mounted inside the first sleeve 58. When the end of the insertion shaft 59 approaches the motor output shaft hole, the insertion shaft 59 overcomes the elastic force of the first spring 510 and slides relative to the first sleeve 58, which passes through the second connecting plate 57 and is fixed to the first connecting plate 56, thereby achieving floating alignment and pressing. The first spring 510 is mounted between the insertion shaft 59 and the first sleeve 58. The first power input seat 511 is mounted inside the fourth frame 51, and the withstand voltage power detector 512 is mounted on the fourth frame 51.

[0024] like Figure 6 As shown in detail, the motor to be tested is equipped with a gear output shaft device, and the gear output shaft device is equipped with a rotating plate 513. The rotating plate 513 is provided with a number of holes 514 evenly spaced around the center position.

[0025] When the motor to be tested is delivered to the testing station, the conductive contacts of the first power input socket 511 are accurately connected to the motor's wiring terminals, thus energizing the motor. After energization, the internal drive device of the motor starts working, the gear output shaft device drives the rotating plate 513 to rotate, the first cylinder 52 starts, and drives the first connecting plate 56, the first mounting plate 53 and its components to move downward. Since the second connecting plate 57 is connected to the first connecting plate 56, the second connecting plate 57 also moves downward, fitting perfectly into the annular space formed between the surface of the rotating plate 513 and the gear output shaft device. The insertion shaft 59 contacts the surface of the rotating plate 513. Under the frictional force generated by the rotation of the rotating plate 513, the insertion shaft 59 is subjected to an inward force, causing the first spring 510 to be compressed, and the insertion shaft 59 retracts into the first sleeve 58. As the rotating plate 513 continues to rotate, when the hole 514 on the rotating plate 513 aligns with the insertion shaft 59, the insertion shaft 59, under the reset action of the first spring 510, will quickly extend into the hole 514. The rotation of the rotating plate 513 will drive the insertion shaft 59, the insulating plate, and the second connecting plate 57 to rotate around the first connecting rod 55. Since the first connecting rod 55 is equipped with an encoder, the encoder can monitor the rotation of the first connecting rod 55 in real time and convert the rotation signal into an electrical signal to feed back to the control system. The control system then accurately calculates the product's speed and direction of rotation. At the same time, the withstand voltage power detector 512 will collect the motor's internal pressure and power data in real time through sensors and transmit this data to the control system. After processing and analyzing the collected data, the control system displays the test data on the display screen, allowing operators to understand the various performance indicators of the motor in a timely manner.

[0026] In detail, a through slot is formed at the center of the first connecting plate 56, and the first connecting rod 55 passes through the through slot. The diameter of the first connecting rod 55 is smaller than the diameter of the through slot. In this way, the first connecting rod 55 is directly connected to the second connecting plate 57 made of insulating material, while being isolated from the first connecting plate 56, achieving metal isolation and improving the stability and accuracy of the detection.

[0027] In detail, the second connecting plate 57 is an insulating plate, which provides metal isolation and enhances stability during testing. During motor testing, the motor generates an electromagnetic field after being powered on. If there is no adequate insulation between the metal components in the testing device, this electromagnetic field may induce currents between them, affecting the accuracy and stability of the detection signal. The second connecting plate 57, made of an insulating plate, effectively isolates the metal components and prevents the generation of induced currents. Thus, the encoder and other testing instruments can accurately acquire parameters such as motor speed, direction of rotation, internal pressure, and power without being affected by electromagnetic interference, thereby improving the accuracy and reliability of the testing.

[0028] Specifically, the insertion shaft 59 is equipped with a limiting ring. During the insertion of the insertion shaft 59 into the hole 514 on the rotating plate 513, when the insertion shaft 59 is inserted to a certain depth, the limiting ring will contact the surface of the rotating plate 513. Due to the blocking effect of the limiting ring, the insertion shaft 59 cannot be inserted further, thus ensuring that the insertion depth of the insertion shaft 59 into the hole 514 is consistent. In this way, when the rotating plate 513 rotates and drives the insertion shaft 59 to rotate, the smoothness and accuracy of the rotation can be guaranteed, avoiding detection errors caused by inconsistent insertion depth.

[0029] like Figures 7-11 As shown, the automatic screw adjustment device 2 includes a first frame 21, a detection device 22, a position adjustment device 23, a first anti-jump device 24, and a current detector 25. The position adjustment device 23 and the current detector 25 are both mounted on the first frame 21. The position adjustment device 23 is used to drive the detection device 22 to move, so that the detection device 22 can quickly reach the detection position. The detection device 22 and the first anti-jump device 24 are both mounted on the position adjustment device 23. The first anti-jump device 24 always applies a radial constraint force to the detection shaft 215 to prevent it from jumping out of the screw head. The detection device 22 includes a third base 26, a first slide rail 27, a second base 28, a second cylinder 29, a second connecting rod 210, a first motor 211, a second sleeve 212, a third connecting rod 213, a second spring 214, and a detection shaft 215. The third base 26 is slidably mounted on the position adjustment device 23. The first slide rail 27 is mounted on the third base 26. The second base 28 is slidably mounted on the first slide rail 27. The second cylinder 29 is respectively mounted on both sides of the second base 28. The second connecting rod 210 is mounted on the output shaft of the second cylinder 29. The first motor 211 is mounted on the second base 28. The second sleeve 212 is mounted on the output shaft of the first motor 211. The third connecting rod 213 is slidably mounted inside the second sleeve 212. The second spring 214 is mounted between the third connecting rod 213 and the second sleeve 212. The detection shaft 215 is mounted on the third connecting rod 213.

[0030] The first frame 21 serves as the supporting structure for the entire automatic screw adjustment device 2, providing a stable mounting base for other components. Position adjustment devices 23 are installed on both sides of the first frame 21 to adjust the positions of the detection device 22 and the first anti-jump device 24. The detection device 22 is responsible for the actual detection operation of the motor adjustment screw, while the first anti-jump device 24 prevents the detection shaft 215 from jumping out of the screw groove during the detection process, ensuring the stability of the detection. A current detector 25 is located on the upper side of the first frame 21 to monitor current changes during the detection process and assist in judging the detection status.

[0031] The third base 26 slides on the position adjustment device 23, realizing the initial position adjustment of the detection device 22 in the horizontal direction. When the second cylinder 29 works, its output shaft drives the second connecting rod 210 to move. The second connecting rod 210 will contact the first anti-jump device 24. Under the reaction force of the first anti-jump device 24, it provides a pushing force for the detection device 22. At this time, the second sleeve 212, the third connecting rod 213 and the detection shaft 215 move towards the product to be detected until the detection shaft 215 aligns with the screw on the product to be detected. It should be noted that the screw surface is a rectangular groove. Since the direction of the groove on the screw surface is not fixed after the product is tightened, if the direction of the detection shaft 215 does not match the groove of the assembled screw, the first motor 211 can be controlled to drive the detection shaft 215 to rotate, and the output shaft can be used to rotate the screw. The shaft drives the second sleeve 212 to rotate, which in turn drives the third connecting rod 213 and the detection shaft 215 to rotate. This is used to adjust the direction of the detection shaft 215 so that it matches the screw groove. When the detection shaft 215 aligns with the rectangular groove on the screw, the second spring 214 acts as a buffer to prevent the detection shaft 215 from damaging the edge of the rectangular groove on the screw. After successful alignment, the first anti-jump device 24 is controlled to move towards the detection device 22 and press the detection device 22, causing a portion of the third connecting rod 213 to extend into the second sleeve 212 until the second spring 214 is fully compressed. This prevents the detection shaft 215 from popping out of the rectangular groove on the screw surface during the detection process, thus improving the stability of the detection process. Then, control the detection shaft 215 to rotate counterclockwise twice to output current, and then rotate it clockwise. First, increase the current, and then adjust the current to the allowable range. Since the current of the motor is closely related to the load torque during operation, when the detection shaft 215 rotates the screw counterclockwise or clockwise, the rotation of the screw will generate a certain load torque. This load torque will act on the motor, causing the motor current to change. By detecting this current change, we can indirectly understand the load situation of the screw rotation. The screw outputs an initial current when rotated counterclockwise, and the current is increased to the preset value when rotated clockwise. We observe whether the power supply enters the current limiting mode, and then gradually reduce the current to the specified range to confirm that the power supply has returned to a stable voltage state without oscillation. At this time, the current meets the load requirements and avoids overheating or damage. During the detection process, the current is monitored in real time by the current detector 25.

[0032] like Figure 10 As shown, the position adjustment device 23 includes a third cylinder 216 and a second slide rail 217. The third cylinder 216 is mounted on the first frame 21, and the second slide rail 217 is mounted on both sides of the first frame 21 and close to the third cylinder 216. The third base 26 is slidably mounted on the second slide rail 217, and the third cylinder 216 is connected to the third base 26.

[0033] Before starting the inspection, it is necessary to ensure that the inspection shaft 215 is accurately aligned with the screw on the motor. If it is found that the inspection component is not aligned with the screw, the third cylinder 216 is activated to push the third base 26 to move along the second slide rail 217, thereby adjusting the position of the inspection device 22 so that the inspection component can be accurately aligned with the screw on the motor, preparing for subsequent inspection work.

[0034] like Figure 8 As shown in detail, the first anti-jump device 24 includes a drive device and a first ejector rod 218. The drive device is disposed on both sides of the top of the third base 26, and the first ejector rod 218 is disposed on the drive device.

[0035] During the testing process, when the testing shaft 215 aligns with the screw groove, the drive device is activated, and its output shaft drives the first ejector rod 218 to extend, causing a portion of the third connecting rod 213 to extend into the second sleeve 212 until the second spring 214 is fully compressed. When the testing shaft 215 drives the screw to rotate, the elasticity of the second spring 214 can prevent the testing shaft 215 from jumping out of the screw groove due to centrifugal force and other factors, thus ensuring the stability of the testing.

[0036] like Figure 11 As shown in detail, the detection shaft 215 has a cylindrical shaft body and a rectangular head. The cylindrical shaft body facilitates sliding and rotation within the second sleeve 212 while ensuring its own strength and stability. The rectangular head is designed to match the rectangular groove on the motor adjusting screw. When the detection shaft 215 rotates to the appropriate direction, the rectangular head can accurately insert into the rectangular groove to detect the screw.

[0037] like Figures 12-17 The turbine cover assembly assembly device 3 includes a second frame 31, a pressing device 32, an energizing device 33, and a first lifting device 34. The pressing device 32, the energizing device 33, and the first lifting device 34 are all mounted on the second frame 31. The pressing device 32 is used to fix the motor to be assembled. The first lifting device 34 is used to lift the eight-tooth shaft inside the motor upward. The energizing device 33 is used to energize the motor to be assembled, so as to facilitate the assembly of the eight-tooth shaft with the turbine cover. The pressing device 32 includes a displacement driving device 35, a fourth cylinder 36, a fourth connecting rod 37, a third slide rail 38, a slider 39, a pressing head 310, a sliding rod 311, and a third spring 312. The displacement driving device 35 is mounted on the second frame 31. The fourth cylinder 36 is symmetrically mounted on both sides of the displacement driving device 35. The fourth connecting rod 37 is mounted on the output end of the fourth cylinder 36. The third slide rail 38 is symmetrically mounted in the middle of the displacement driving device 35. The sliders 39 are slidably mounted on the third slide rail 38. The pressing heads 310 are mounted on the sliders 39. The sliding rods 311 are mounted on the side of the pressing head 310 near the fourth cylinder 36. The fourth connecting rod 37 is slidably connected to the sliding rod 311. The third spring 312 is connected between the sliding rod 311 and the fourth connecting rod 37.

[0038] The motor to be assembled with the turbine cover is placed on the assembly station. Then, the turbine cover to be assembled is placed inside the motor. The displacement drive device 35 is then controlled to move the third slide rail 38, the fourth cylinder 36, and other components on it until the pressure head 310 moves to the position directly above the turbine cover. Then, the fourth cylinder 36 is activated, and its output end pushes the fourth connecting rod 37 downward. The fourth connecting rod 37 is slidably connected to the slide rod 311, and the slide rod 311 is located on the side of the pressure head 310 near the fourth cylinder 36. At the same time, the slider 39 is slidably positioned. On the third slide rail 38, the pressure head 310 is mounted on the slider 39. During the downward movement of the fourth connecting rod 37, the pressure head 310 is driven to move downward through the sliding engagement with the slide rod 311 and the sliding of the slider 39 on the third slide rail 38, thereby pressing the motor product from above. The third spring 312 is connected between the slide rod 311 and the fourth connecting rod 37. During the downward pressing process, the third spring 312 plays a buffering role to prevent the turbine cover from being damaged due to excessive direct downward pressure, and to ensure that the turbine cover is not damaged during the assembly process. Subsequently, the energizing device 33 energizes the motor, which rotates slowly. The first lifting device 34 lifts the eight-tooth shaft inside the motor upward to engage with the turbine cover. Since it is uncertain whether the engagement is successful on the first attempt after the eight-tooth shaft is lifted upward, the contact between the eight-tooth shaft and the cover plate of the turbine cover increases friction. The slow rotation of the motor will drive the turbine cover to rotate. However, there is a certain amount of friction between the eight-tooth shaft and the turbine cover. When the turbine cover rotates, it will not drive the eight-tooth shaft to rotate. This avoids the problem that the motor's slow rotation will drive the turbine cover to rotate synchronously, and the turbine cover's rotation will also drive the eight-tooth shaft to rotate synchronously, resulting in both rotating together and the eight-tooth shaft and the turbine cover not being able to engage. The eight-tooth shaft is lifted upward, protruding a few millimeters from the surface of the turbine cover, and then falls down. In this way, the eight-tooth shaft and the turbine cover are engaged, and the assembly is successful. In detail, the turbine cover assembly includes a turbine, a cover plate, and a buffer block. The cover plate is disposed on the surface of the turbine and has a through hole that meshes with the eight-tooth shaft. The buffer block is disposed between the turbine and the cover plate. Through the cooperation of the first lifting device 34 and the pressing device 32, the motor and the turbine cover are respectively limited and fixed to prevent the cover plate from detaching from the buffer block during the assembly process.

[0039] like Figure 17 As shown, the first lifting device 34 includes a fifth cylinder 313 and a push rod 314. The fifth cylinder 313 is located at the bottom of the second frame 31, and the push rod 314 is located at the output end of the fifth cylinder 313.

[0040] The fifth cylinder 313 starts, and its output end extends upward, driving the push rod 314 to move upward. The upward movement of the push rod 314 lifts the eight-tooth shaft upward, increasing the relative sliding friction between the eight-tooth shaft and the turbine cover. During the subsequent rotation of the motor, if there is insufficient friction, the motor may drive the turbine and worm gear to rotate together, causing the turbine cover to fail to mesh smoothly with the eight-tooth shaft. Moreover, after the eight-tooth shaft meshes with the turbine cover, that is, after the eight-tooth shaft passes through the through hole in the cover plate, the eight-tooth shaft will be lifted to a height of millimeters higher than the top of the turbine cover plate. This ensures that when the eight-tooth shaft falls down, it will not cause the turbine cover to detach, thus ensuring the stability of the assembly.

[0041] like Figure 16 As shown in detail, the power supply device 33 includes a drive device and a second power input socket 315. The drive device is disposed in the second frame 31. There are two drive devices, and each drive device is a cylinder. The second power input socket 315 is disposed on the drive device.

[0042] When the motor is pressed down by the upper pressing device 32 and the bottom eight-tooth shaft is also lifted, the two drive devices start, driving the second power input socket 315 mounted on it to move towards the motor, so that the second power input socket 315 connects with the power interface on the motor, thereby powering the product. After the motor is powered on, it starts to rotate slowly. The motor speed is very slow after being powered on to avoid the turbine cover assembly being difficult to engage if the speed is too fast. Since the through holes on the cover plate are cross-shaped, the motor can generally complete the engagement assembly within 90 degrees of rotation.

[0043] like Figure 16 As shown in detail, the second frame 31 is also provided with a fixed pressure plate 316. When the lifting device lifts the motor to be assembled upward until the motor to be assembled contacts the fixed pressure plate 316, the fixed pressure plate 316 fixes and limits the motor to be assembled.

[0044] like Figures 18-22As shown, the automatic snap ring mounting device 4 includes a third frame 41, a pressing device 42, and a second lifting device 43. Both the pressing device 42 and the second lifting device 43 are mounted on the third frame 41. The second lifting device 43 is used to lift the eight-tooth shaft upwards to protrude from the motor surface, so that the snap ring can be mounted on the eight-tooth shaft in the future. The pressing device 42 includes a sixth cylinder 44, a pressing sleeve 45, a seventh cylinder 46, grippers 47, and a guide shaft 48. The sixth cylinder 44 is located on one side of the third frame 41. The pressing sleeves 45 are all located at the output end of the sixth cylinder 44. The seventh cylinder 46 is located on the third frame 41 on the side close to the sixth cylinder 44. The grippers 47 are symmetrically arranged on the seventh cylinder 46. The two grippers 47 move in opposite directions and move towards each other to clamp the guide shaft 48. The guide shaft 48 is located directly below the pressing sleeve 45.

[0045] After the motor to be assembled with the retaining ring moves to the assembly station, the second lifting device 43 is controlled to lift the eight-tooth shaft inside the motor upwards to facilitate the subsequent assembly of the retaining ring. Specifically, the top of the eight-tooth shaft is provided with a groove. Then, the gripper 47 on the seventh cylinder 46 is controlled to separate, so that the guide shaft 48 is inserted into the groove. Then, the seventh cylinder 46 is controlled to drive the gripper 47 to close and fix the guide shaft 48. Subsequently, the automatic feeding fixture of the retaining ring will place the retaining ring on the guide shaft 48. At this time, the seventh cylinder 46 drives the gripper 47 to separate, and the retaining ring moves downward through the guide shaft 48. Then, the sixth cylinder 44 is controlled to work to drive the pressing sleeve 45 to move downwards, so that the pressing sleeve 45 moves downwards along the guide shaft 48 to achieve pressing.

[0046] like Figure 21 As shown, the guide shaft 48 has a frustum-shaped upper part and a cylindrical lower part. The diameter of the bottom of the frustum is the same as the diameter of the lower cylinder. A protruding post is provided at the bottom of the guide shaft 48, and the guide shaft 48 is integrally formed. The frustum-shaped structure at the top of the guide shaft 48 serves a guiding function. When the pressing sleeve 45 presses down on the retaining ring, the frustum-shaped structure guides the retaining ring smoothly along its inclined surface onto the guide shaft 48, making the assembly process more accurate and smooth. The lower cylindrical part of the guide shaft 48 has the same inner diameter as the retaining ring, preventing the center of the retaining ring from shifting and affecting its assembly. Simultaneously, the lower cylindrical part of the guide shaft 48 provides a stable clamping surface for the gripper 47, ensuring that the gripper 47 can firmly clamp the guide shaft 48. The protruding post at the bottom of the guide shaft 48 engages with the groove at the top of the eight-tooth shaft, serving a positioning and guiding function, further ensuring the stability of the guide shaft 48 during assembly. The one-piece molding design gives the guide shaft 48 high strength and precision, which can meet the high requirements of automated assembly of motor snap rings and ensure assembly quality and efficiency.

[0047] like Figure 22As shown, the second lifting device 43 includes a driving device and a second ejector rod 49. The driving device is located on the lower side of the third frame 41 and is a cylinder. The second ejector rod 49 is located on the output end of the driving device. By controlling the operation of the driving device, the second ejector rod 49 is driven to lift upward, so that the second ejector rod 49 lifts the eight-tooth shaft inside the motor upward, so that the top part of the eight-tooth shaft can extend out of the motor surface, which facilitates the subsequent assembly of the retaining ring onto the eight-tooth shaft.

[0048] like Figures 23-28 As shown, the automatic cover installation device 6 includes a fifth frame 61, an installation device 62, a lifting device 63, and a second anti-jump device 64. The lifting device 63 is mounted on the fifth frame 61, and both the installation device 62 and the second anti-jump device 64 are mounted on the lifting device 63. This allows the installation device 62 to move up and down to a suitable height for the installation of the motor cover to be assembled. The installation device 62 is used to install the cover onto the motor to be assembled. The second anti-jump device 64 is used to fix the components of the installation device 62 to prevent the installation device 62 from detaching from the cover due to vibrations or other factors caused by the rotation of the motor to be assembled during the installation process.

[0049] The mounting device 62 includes a mounting frame 65, a second motor 66, a rotating shaft 67, a fixed seat 68, and a tightening head 69. The mounting frames 65 are all mounted on the lifting device 63, the second motors 66 are all mounted on the mounting frames 65, the rotating shafts 67 are all mounted on the output shafts of the second motors 66, the fixed seats 68 are all located at the bottom of the rotating shafts 67, and the tightening heads 69 are all located at the bottom of the fixed seats 68.

[0050] The second motor 66 is mounted on the mounting bracket 65 as a power source to provide power for the tightening action. The rotating shaft 67 is mounted on the output shaft of the second motor 66. The fixed seat 68 is mounted on the bottom of the rotating shaft 67. The tightening head 69 is mounted on the bottom of the fixed seat 68. When the second motor 66 rotates and drives the rotating shaft 67 to rotate, the tightening head 69 also rotates. The torque generated by the rotation tightens the motor housing cover to be assembled onto the corresponding component, thus completing the installation action.

[0051] like Figure 25As shown in detail, the lifting device 63 includes a support plate 610, a drive device, a connecting shaft 611, an elastic element 612, a connecting block 613, and a guide device 614. The support plate 610 is mounted on the worktable, and the drive device is located on both sides of the support plate 610 as the power source for lifting. The connecting shafts 611 are all located on the output end of the drive device, and the connecting blocks 613 are all located at the ends of the connecting shafts 611. The elastic element 612 is located between the connecting block 613 and the connecting shaft 611. The mounting bracket 65 is connected to the connecting block 613. Next, when the connecting block 613 moves, it drives the mounting frame 65 to move up and down together. The guide device 614 is set on the support plate 610 and is connected to the mounting frame 65. The function of the guide device 614 is to restrict the movement direction of the mounting frame 65, so that it can only move up and down in the vertical direction, ensuring the stability and accuracy of the mounting device 62 during the lifting process. In detail, the guide device 614 includes a slide rail and a slider. The slide rail is set on the support plate 610, and the slider is connected to the mounting frame 65. The slider is slidably connected to the slide rail.

[0052] During the downward movement of the lifting device 63 and the installation device 62, the elastic element 612 is compressed. Subsequently, the second motor 66 slowly drives the tightening head 69 to rotate. The purpose of this slow rotation is to ensure that the tightening head 69 does not match the groove on the surface of the lid, thus creating a misalignment between the tightening head 69 and the groove. This continues until the tightening head 69 slowly rotates to align with the groove on the lid surface. At this point, under the action of the elastic element 612, the installation device 62 will continue to move downward until the tightening head 69 extends into the groove on the lid surface and contacts the bottom of the groove. Then, the second motor 66 is controlled to rotate rapidly, thereby tightening the lid by the tightening head 69. During the tightening process, because the groove on the lid surface is shallow, the drive device inside the second anti-jump device 64 drives the limit rod 615 to move downward. The limit rod 615 presses against the installation frame 65, preventing the tightening head 69 from detaching from the groove on the lid surface during installation.

[0053] like Figure 26 As shown, the second anti-jump device 64 includes a drive unit and limit rods 615. The drive unit is located on both sides of the support plate 610, and the limit rods 615 are located on the output ends of the drive unit. The limit rods 615 are in contact with the mounting bracket 65. When the drive unit extends, the limit rods 615 move downward and abut against the mounting bracket 65, thereby limiting the jumping of the tightening head 69 in the vertical direction. This prevents the tightening head 69 from detaching from the cover due to vibrations caused by the rotation of the motor to be assembled during installation, thus ensuring the stability and accuracy of the installation. After installation, the drive unit on the second anti-jump device 64 retracts, and the limit rods 615 retract, without affecting the lifting and lowering movement of the mounting bracket 65.

[0054] like Figure 24As shown in detail, the mounting bracket 65 is equipped with a displacement sensor 616, which detects whether the motor to be assembled is covered with a cover 10.

[0055] like Figures 29-34 As shown, the automatic glue application device 7 includes a sixth frame 71, a glue application device 72, and a glue scraping device 73, with both the glue application device 72 and the glue scraping device 73 mounted on the sixth frame 71. The adhesive application device 72 includes an X-axis displacement device 74, a Y-axis displacement device 75, a Z-axis displacement device 76, an adhesive application head 77, an eighth cylinder 78, a third mounting plate 79, a ninth cylinder 710, and a cable dragger 711. The X-axis displacement device 74 is mounted on one side of the sixth frame 71, the Y-axis displacement device 75 is mounted on the X-axis displacement device 74, the Z-axis displacement device 76 is mounted on the Y-axis displacement device 75, the adhesive application head 77 is mounted on the Z-axis displacement device 76, and the eighth cylinder 78 is mounted on the Z-axis displacement device 76. The X-axis displacement device 74, the Y-axis displacement device 75, and the Z-axis displacement device 76 work together to move the adhesive application head 77 in three dimensions. The third mounting plate 79 is mounted on the output end of the eighth cylinder 78, the ninth cylinder 710 is mounted on the third mounting plate 79, and the cable dragger 711 is symmetrically mounted on the ninth cylinder 710.

[0056] During glue application, the motor is manually rotated 180 degrees so that the wire clips and harnesses to be glued face upwards. The glue application device achieves precise movement of the glue application head 77 in three-dimensional space through X-axis, Y-axis, and Z-axis displacement devices. The X-axis displacement device provides power, driving the Y-axis displacement device to move upwards along the X-axis, thus achieving movement of the glue application device in the X-axis direction; the Y-axis displacement device drives the Z-axis displacement device to slide along the Y-axis, thus moving the glue application device in the Y-axis direction; the Z-axis displacement device drives the glue application head 77 to slide along the Z-axis, thus achieving movement of the glue application device in the Z-axis direction. Through the coordinated movement of the three axial displacement devices, the glue application head 77 can accurately reach the glue application position in three-dimensional space to perform the glue application operation. Since the wire harness on the motor connector may block the glue application position, the X-axis displacement device, Y-axis displacement device and Z-axis displacement device work together to move the glue application head 77 to the glue application position. Then, the ninth cylinder 710 is controlled to work, causing the two wire pulling claws 711 to separate and clamp the wire harness on the motor. The ninth cylinder 710 is controlled again to work, causing the two wire pulling claws 711 to close and clamp the wire harness. Then, the eighth cylinder 78 is controlled to work, driving the entire ninth cylinder 710, wire pulling claws 711 and the clamped wire harness to move sequentially along the Y-axis, so that the glue application head 77 can apply glue to both sides of the connector in turn.

[0057] like Figure 34As shown in detail, the glue scraping device 73 is equipped with a fixed pressure head 712. When the lifting device lifts the tray 9 upward until the top of the assembled motor contacts the fixed pressure head 712, the fixed pressure head 712 will flatten the tilted motor, so that the motor can be in a horizontal state. This avoids the problem of the motor being placed unevenly after manual flipping, which would cause the glue applicator 77 to collide with the motor, and also avoids the problem of glue overflowing in all directions due to the tilt of the motor after the glue is applied to the motor.

[0058] like Figure 18 As shown, it also includes a detection device, which is installed on the automatic snap-fit ​​device 4. The detection device includes an electric guide device 410 and a detector 411. The electric guide device 410 is installed on the side of the third frame 41 away from the sixth cylinder 44, and the detector 411 is installed on the electric guide device 410.

[0059] like Figure 22 As shown, lifting devices are provided on the lower side of the second frame 31, the third frame 41, the fourth frame 51, the fifth frame 61 and the sixth frame 71. The lifting devices are used to lift the motor to be assembled upward. The lifting devices include a tenth cylinder 10 and a lifting plate 11. The tenth cylinder 10 is respectively located on the lower side of the second frame 31, the third frame 41, the fourth frame 51, the fifth frame 61 and the sixth frame 71, and the lifting plate 11 is provided on the tenth cylinder 10.

[0060] The motor housing integrated unit 1 includes an automatic feeding and marking device, a ball bearing and spring assembly device, and a gearbox automatic oiling device connected in sequence.

[0061] The automatic feeding and marking device is used to feed and mark the motor housing, then automatically press the bushing onto the housing, and feed the ball bearing and spring. The product posture is then adjusted to ensure stability before pressing the ball bearing into place. After pressing, the gearbox is automatically lubricated, and the screw assembly is tightened. The housing then exits the production line and is automatically welded by manual wiring. The core components of the motor are then installed into the housing and automatically locked in place. Next, the screws are automatically adjusted, and the housing is automatically lubricated after adjustment. The turbine cover is then assembled, followed by automatic assembly of the retaining ring. The next step is automatic motor testing. After testing, the motor housing cover is installed, and finally, the motor's wire clips are automatically glued. After glue application, the product is automatically unloaded.

[0062] The first frame 21, the second frame 31, the third frame 41, the fourth frame 51, the fifth frame 61, and the sixth frame 71 are all connected by a conveying assembly. The conveying assembly includes a slide rail 8 and a tray 9. The tray 9 is slidably mounted on the slide rail 8 and is a traveling tool. It is equipped with a contour positioning groove and a quick pneumatic clamp that are perfectly matched to the base of a specific model of motor. The motor to be assembled is placed on the tray 9. When the tray 9 moves to each assembly station in sequence, the tenth cylinder 10 of that station is controlled to work, so that the tenth cylinder 10 drives the lifting plate 11 to move upward, thereby lifting the tray 9 and its components upward to facilitate motor assembly.

[0063] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
