Description

Technical Field

[0001] This technical solution relates to the field of motor assembly equipment technology, specifically to a motor assembly equipment. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction.

[0003] Existing motor structures typically include a casing, stator, rotor, front cover, rear cover, oil seal, and coil. These components need to be assembled together. Currently, the commonly used motor assembly production method generally adopts the traditional model, in which each step of the processing flow mainly relies on operators to manually complete the assembly. This method is not only cumbersome and time-consuming, but also requires a large investment of labor costs, resulting in low overall production efficiency. Summary of the Invention

[0004] This technical solution aims to improve the low production efficiency caused by manual assembly of existing motors by providing a motor assembly equipment.

[0005] The purpose of this technical solution is achieved as follows:

[0006] An electric motor assembly device includes a base and a frame mounted on the base, and further includes:

[0007] A conveying device, which is mounted on the machine base and can be aligned with multiple workstations, is used to convey the workpiece from the previous workstation to the next workstation.

[0008] A hot feeding device is installed on the machine base for feeding the barrel and heating the barrel during feeding.

[0009] The first assembly device is mounted on the frame and is used to heat-fit the heated barrel onto the corresponding stator and coil, and press the rear cover and rotor onto another barrel equipped with a rear cover.

[0010] A front cover mounting device, which is mounted on the frame, is used to press the oil seal and the front cover onto the barrel equipped with the stator and coil;

[0011] A front cover connecting device, which is mounted on the base, is used to bolt the front cover to the barrel;

[0012] A flipping device, mounted on the frame, is used to flip the cylinder bolted to the front cover.

[0013] A rear cover connecting device, mounted on the base, is used to bolt the rear cover to the barrel; and

[0014] The second assembly device, which is mounted on the base, is used to install the fan blades onto the barrel with a bolted rear cover and to feed the barrel equipped with the fan blades out as unloaded material.

[0015] Through the above technical solution, when a motor assembly equipment is in normal use, a circular production line is formed by connecting various workstations through a conveying device. In the initial first workstation, workpieces are loaded. The stator and coil assembly, and the oil seal and front cover assembly are manually or mechanically loaded onto the conveying device, and the barrel is loaded onto the heating supply device, which heats the barrel. In the second workstation, the first assembly device grabs the heated and expanded barrel, transfers it, and heat-fits it onto the stator and coil. At the same time, the first assembly device also performs a pressing operation between the rotor shaft, the rear cover, and the barrel from the previous process. In the third workstation, the front cover installation device grabs the oil seal and front cover assembly, transfers it, and presses it onto the barrel. In the fourth workstation, the front cover connecting device screws the front cover into place. The rotor is bolted to the barrel; in the fifth station, the flipping device grabs the barrel and rotates it in the air at a specific angle (180 degrees) so that the front cover of the barrel is placed back with its orientation downwards; it returns to the first station, where the rotor and rear cover are installed on the barrel, and the workpiece loading process in the next step is executed. Then, in the second station, the first assembly device presses the rotor shaft, rear cover, and barrel together; in the sixth station, the rear cover connecting device bolts the rear cover to the barrel; in the seventh station, the second assembly device grabs the fan blade and fits it onto the rotor shaft. After assembly, it grabs the barrel for unloading; the entire process achieves automated assembly line operation from parts to finished products through the orderly spatial layout and precise temporal coordination of each device, thereby improving the production efficiency of the product.

[0016] Preferably, the heat supply device includes:

[0017] The feeding assembly includes a feeding frame, a feeding seat that slides on the feeding frame, and a feeding drive component. The feeding seat is used to place the machine cylinder, and the feeding drive component drives the feeding seat to move for feeding.

[0018] The transfer assembly includes a transfer frame, a transfer mechanism, and a first transfer drive component. The transfer mechanism includes a transfer slide plate that slides on the transfer frame, a transfer clamp that slides on the transfer slide plate, and a second transfer drive component. The first transfer drive component is used to drive the transfer slide plate to move, and the second transfer drive component is used to drive the transfer clamp to move. The movement directions of the transfer slide plate and the transfer clamp are perpendicular. The transfer clamp is used to clamp the loading barrel to the heating assembly.

[0019] An air blowing assembly, which is mounted on the feeding seat, is used to blow air into the inside of the barrel;

[0020] Heating components are used to heat the inside of the barrel.

[0021] The above technical solution involves placing the barrel on the loading seat, blowing air into the inside of the barrel to remove debris and impurities from the internal assembly surfaces, and driving the loading seat towards the heating component. Transfer drive one drives the transfer slide plate to slide horizontally, while transfer drive two drives the transfer clamp to move up and down. The combined movement of these two vertical directions enables the transfer clamp to operate flexibly in a two-dimensional plane. The transfer clamp picks up the barrel loaded on the loading seat and places it onto the heating component, which heats the barrel to expand it, facilitating subsequent assembly operations.

[0022] Preferably, the first assembly device includes:

[0023] Assemble slide plate one, which is slidably mounted on the frame;

[0024] A barrel assembly assembly includes an assembly frame slidably disposed on an assembly slide plate, an assembly motor, an assembly fixture disposed below the assembly frame, and a buffer pressure head. The assembly motor drives the assembly frame to move so that the assembly fixture clamps the barrel. The buffer pressure head is used to press the barrel, stator, and coil.

[0025] The rear cover pressing assembly includes a pressing frame slidably mounted on an assembly slide plate, a pressing motor, an assembly pressing head disposed below the pressing frame, and a fixed shaft structure. The fixed shaft structure includes a fixed shaft slide rod slidably within the assembly pressing head and a fixed shaft drive component. The pressing motor drives the pressing frame to move, and the fixed shaft slide rod is parallel to the moving direction of the pressing frame, thereby moving the fixed shaft slide rod to press against the rotor shaft. When the fixed shaft drive component drives the fixed shaft slide rod to retract, the assembly pressing head presses the rear cover against the barrel.

[0026] An assembly drive component is provided, which is mounted on the assembly slide plate. The output end of the assembly drive component is connected to the frame and is used to drive the assembly slide plate to move.

[0027] Through the above technical solution, the assembly drive unit drives the assembly slide plate to move horizontally, and the assembly motor drives the assembly frame to move up and down. The two vertical movements work together to drive the assembly fixture and the buffer pressure head to operate flexibly in a two-dimensional plane. The assembly fixture can grip the heated and expanded barrel, heat-fit the barrel onto the stator and coil, and apply pressure to the barrel through the buffer pressure head to ensure stable assembly.

[0028] The press motor drives the press frame to move up and down. Through the coordinated movement in two vertical directions, the assembly press head and the fixed shaft structure operate flexibly in a two-dimensional plane. First, the fixed shaft slide rod protrudes from the assembly press head and presses against the rotor shaft to engage with the front cover. The fixed shaft drive component drives the fixed shaft slide rod to retract, and the assembly press head descends to press down on the rear cover, thereby pressing the rear cover onto the barrel. The barrel assembly assembly and the rear cover pressing assembly perform operations on two workpieces in the two processes, respectively.

[0029] Preferably, the front cover mounting device includes:

[0030] A front cover mounting assembly includes a mounting plate 1 disposed on a frame, a mounting bracket 1 sliding on the mounting plate 1, a mounting drive component 1, and a mounting mechanism. The mounting drive component 1 drives the mounting bracket 1 to move up and down. The mounting mechanism includes a mounting plate 2 disposed below the mounting bracket, a mounting bracket 2 sliding on the mounting plate 2, a mounting drive component 2, and a mounting clamp. The mounting drive component 2 drives the mounting bracket 2 to move, and the moving direction of the mounting bracket 2 is perpendicular to that of the mounting bracket 1, so as to move the mounting clamp to clamp the front cover equipped with an oil seal and install the front cover onto the barrel.

[0031] The front cover mounting assembly includes a mounting plate disposed on the frame, a mounting frame sliding on the mounting plate, a mounting drive component, and a mounting pressure head disposed at the lower part of the mounting frame. The mounting drive component drives the mounting frame to move up and down, thereby moving the mounting pressure head to press the front cover and the barrel together.

[0032] Through the above technical solution, the first installation drive component drives the first mounting frame to move up and down, and the second installation drive component drives the second mounting frame to move horizontally. The two vertical movements work together to drive the installation fixture to operate flexibly in a two-dimensional plane. The installation fixture picks up the front cover with the oil seal from the conveying device, aligns the front cover and places it on the end face of the barrel. The position of the fixed installation pressure head is aligned with the workpiece, and the fixed installation drive component drives the fixed installation frame to move up and down, so as to drive the fixed installation pressure head to press against the front cover, thereby realizing the press-fitting and fixing between the front cover and the barrel.

[0033] Preferably, the front cover connecting device includes:

[0034] A connecting frame 1 is mounted on the machine base;

[0035] Connecting seat one, which is slidably disposed on the side of the connecting frame one;

[0036] The front cover screw-on assembly includes a screw-on slide seat slidably mounted on a connecting frame, a screw-on drive unit disposed on the connecting frame, and four bolt connectors. Each bolt connector includes a connecting motor disposed on the screw-on slide seat and a bolt connector head rotatably disposed on the connecting frame. The screw-on drive unit drives the screw-on slide seat to move, thereby causing the bolt connectors to move synchronously. The connecting motor drives the bolt connector head to rotate, for tightening the bolts into the screw holes of the barrel.

[0037] A connecting drive component is disposed on the connecting frame and is used to drive the connecting seat to move up and down.

[0038] Through the above technical solution, the connecting drive component drives the connecting seat to move up and down, so as to move the front cover screw assembly closer to or away from the corresponding barrel. The four bolt connectors correspond to the four through holes of the front cover. The screw drive component drives the screw slide to move towards the barrel. Each connecting motor synchronously drives the corresponding bolt connector to rotate. With the continuous downward feed of the screw slide, the four bolts are stably screwed into the four front screw holes of the barrel, automatically realizing the bolt connection between the front cover and the barrel, and improving assembly efficiency.

[0039] Preferably, the flipping device includes:

[0040] A transfer slide plate, which is slidably mounted on the frame;

[0041] A material transfer assembly includes a material transfer frame sliding on a material transfer slide, a material transfer drive unit, a tilting clamp, and a tilting drive unit. The material transfer drive unit drives the material transfer frame to move up and down. The tilting clamp is rotatably connected to the lower part of the material transfer frame and is used to clamp a machine barrel bolted to a front cover. The tilting drive unit drives the tilting clamp to rotate, so that the tilting clamp drives the machine barrel to rotate synchronously.

[0042] The second material transfer drive unit is mounted on the frame and is used to drive the material transfer slide to move. The material transfer slide is perpendicular to the moving direction of the material transfer frame.

[0043] Through the above technical solution, the second material transfer drive unit drives the material transfer slide to move horizontally, and the first material transfer drive unit drives the material transfer frame to move up and down. Through the cooperation of the two vertical movements, the flipping fixture operates flexibly in a two-dimensional plane. The flipping fixture clamps the cylinder with the front cover bolted on and lifts the cylinder to a suitable height. The flipping drive unit drives the flipping fixture to rotate, along with the cylinder, to rotate 180 degrees around the horizontal axis, changing the spatial orientation of the front cover to downward. The cylinder is then placed back into the conveying device, completing the posture change of the cylinder. This facilitates the subsequent assembly process of the rear cover and further improves production efficiency.

[0044] Preferably, the rear cover connecting device includes:

[0045] Connecting bracket two is mounted on the machine base;

[0046] Connecting seat two is slidably disposed on the side of connecting frame two;

[0047] The rear cover screw-on assembly includes a screw-on slide block 2 that slides on a connecting frame 2, a screw-on drive component 2 disposed on the connecting frame 2, and four bolt connectors 2. Each bolt connector 2 includes a connecting motor 2 disposed on the screw-on slide block 2 and a bolt connector head 2 rotatably disposed on the connecting frame 2. The screw-on drive component 2 drives the screw-on slide block 2 to move, thereby causing the bolt connectors 2 to move synchronously. The connecting motor 2 drives the bolt connector head 2 to rotate, for tightening the bolts into the screw holes of the barrel; and

[0048] A second connecting drive component is disposed on the second connecting frame and is used to drive the second connecting seat to move up and down.

[0049] Through the above technical solution, the connecting drive component 2 drives the connecting seat 2 to move up and down, so as to drive the rear cover screw assembly to move closer to or away from the corresponding barrel. The four bolt connectors 2 correspond to the four through holes of the rear cover. The screw drive component 2 drives the screw slide 2 to move towards the barrel. Each connecting motor 2 synchronously drives the corresponding bolt connector head 2 to rotate. With the continuous downward feed of the screw slide 2, the four bolts are stably screwed into the four rear screw holes of the barrel, automatically realizing the bolt connection between the rear cover and the barrel, and improving assembly efficiency.

[0050] Preferably, the second assembly device includes:

[0051] Frame;

[0052] Assemble slide plate two, which is slidably mounted on the frame;

[0053] A fan blade feeding assembly includes a vibratory feeder, a conveyor belt, and a feeding mechanism. The conveyor belt is connected to the output end of the vibratory feeder and has a material preparation port for preparing the fan blade. The feeding mechanism includes a feeding drive and a feeding rod. The feeding rod is movably disposed relative to the conveyor belt. The feeding drive drives the feeding rod to move. The feeding rod is used to push the fan blade in the material preparation port to feed material to the fan blade assembly assembly.

[0054] A fan blade assembly assembly includes an assembly frame two slidably mounted on an assembly slide plate two, an assembly motor two, a feeding clamp disposed at the lower part of the assembly frame two, and a mandrel slidably mounted on the feeding clamp. The mandrel is provided with an elastic element, the two ends of which are respectively connected to the feeding clamp and the mandrel. The elastic force of the elastic element has a tendency to push the mandrel outward. The assembly motor two drives the assembly frame two to move up and down. The mandrel is used to engage the fan blade. When the mandrel abuts against the rotor shaft, relative movement occurs between the feeding clamp and the mandrel, causing the feeding clamp to push the fan blade onto the rotor shaft.

[0055] Assembly drive component two is mounted on the frame. The base is equipped with a feeding fixture. Assembly drive component two drives assembly slide plate two to move. The feeding fixture is used to clamp the barrel equipped with fan blades and transfer it to the feeding fixture.

[0056] Through the above technical solution, the vibratory feeder sorts and outputs the stored fan blades to the conveyor belt, which transports them to the preparation port. The preparation port can only hold one fan blade at a time. The feeding drive unit drives the feeding bar to move up and down, pushing the fan blade in the preparation port to the waiting position. The assembly drive unit two drives the assembly slide plate two to move horizontally, and the assembly motor two drives the assembly frame two to move up and down. Through the cooperation of the two vertical movements, the unloading clamp and the mandrel of the unloading clamp operate flexibly in a two-dimensional plane. The mandrel is aligned with the shaft hole of the fan blade, and the fan blade is clamped on the mandrel. Then the mandrel is moved to align with the rotor shaft. During the process of the mandrel contacting the shaft, the spring is compressed and it retracts into the unloading clamp. The unloading clamp then removes the fan blade and mounts it on the shaft. After that, the unloading clamp clamps the entire barrel and transfers it to the unloading fixture. The elastic design of the mandrel realizes the gripping of the fan blade and the flexible pressing on the shaft, improving production efficiency.

[0057] Preferably, the conveying device includes:

[0058] A transfer table, which is rotatably connected to the frame;

[0059] Several material-carrying fixtures are circumferentially distributed on the rotating platform around its rotation axis. Each material-carrying fixture includes a first material carrier, a second material carrier, and a third material carrier. The first material carrier is used to prepare the stator and coils; the second material carrier is used to prepare the front cover with an oil seal; and the third material carrier is used to place the machine barrel.

[0060] A turntable drive unit is mounted on the machine base and is used to drive the turntable to rotate.

[0061] Through the above technical solution, the turntable drive drives the transfer table to rotate intermittently on the frame, so that several material-carrying fixtures fixed on it pass through each station in the circumferential direction. Each material carrier adopts a split design: material carrier one carries the stator and coil, material carrier two carries the front cover and oil seal, and material carrier three carries the machine barrel. The transfer table stops once after each division of rotation. The devices at each station work synchronously. After the operation is completed, the transfer table rotates again to transport the workpiece to the next station. The rotary conveyor realizes the precise flow and rhythmic production of multiple types of workpieces between each dedicated station, improving the continuity of equipment operation and production efficiency.

[0062] Preferably, the machine base is provided with a temperature detection device and a smoke exhaust device corresponding to the heat supply device. The temperature detection device is used to monitor the heating temperature of the barrel, and the smoke exhaust device is used to remove smoke.

[0063] The base is also equipped with a cooling air device, which is used to blow cold air into the barrel for cooling.

[0064] Through the above technical solution, the temperature detection device is set near the heating component to monitor the barrel heating temperature in real time and ensure that the optimal heat-shrinking temperature range is reached; the smoke generated by heating is promptly sucked away by the smoke exhaust device to keep the working environment clean; after the barrel completes the heat-shrinking and moves to the next station, the cold air device blows cold air onto the outer wall of the barrel to accelerate its local cooling, stabilize the assembly dimensions and shorten the process cycle, thus ensuring the stability, safety and assembly quality of the heating process.

[0065] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0066] This technical solution utilizes a conveying device, a hot material supply device, a first assembly device, a front cover installation device, a front cover connection device, a flipping device, a rear cover connection device, and a second assembly device in coordination. The conveying device connects each workstation in series, driving the workpiece to automatically flow and precisely align between processes. It collaboratively completes processes such as loading and heating the barrel, hot-fitting the barrel onto the stator and coil, front cover installation, front cover bolt fixing, rear cover bolt fixing, and fan blade installation, forming a continuous and directional automated process that improves production efficiency.

[0083] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0084] Example:

[0085] See Figure 1 and Figure 2 An electric motor assembly machine is used to install stators and coils, oil seals and front covers, rear covers and fan blades on a casing. It includes a base 11 and a frame 12 mounted on the base 11. It also includes a conveying device 2, a hot material supply device 3, a front cover connecting device 6, a rear cover connecting device 8 and a second assembly device 9 mounted on the base 11, and a first assembly device 4, a front cover mounting device 5 and a flipping device 7 mounted on the frame 12.

[0086] See Figure 3The conveying device 2 includes a transfer platform 21, several material-carrying fixtures 22, and a turntable drive. The turntable drive is fixedly mounted on the machine base 11. The transfer platform 21 is positioned above the turntable drive and rotates relative to the machine base 11. The turntable drive drives the transfer platform 21 to rotate around its own axis (clockwise). Several material-carrying fixtures 22 are arranged circumferentially on the transfer platform 21 around its rotation axis. The number of material-carrying fixtures 22 is eight, depending on actual needs. The transfer platform 21 rotates intermittently (45° each time) to drive... The loading fixture 22 passes through each station in sequence; each loading fixture 22 includes a loading seat 1 221, a loading seat 222 and a loading seat 3 223. The loading seat 1 221 is located on the inner side of the loading seat 3 223 near the rotation axis of the transfer table 21. It is used to prepare the stator and coil in the first station. The loading seat 3 223 is used to receive the barrel after it has been flipped by the flipping device 7 in the fifth station. The loading seat 2 222 is located on the side of the loading seat 1 221 and the loading seat 3 223. It is used to prepare the front cover with the oil seal in the first station.

[0087] See Figure 4 The hot material supply device 3 is located in the second working position. The hot material supply device 3 includes a feeding assembly 31, a transfer assembly 32, and a heating assembly 34. The feeding assembly 31 includes a feeding frame 311, a feeding seat 312, and a feeding drive component 313. The feeding frame 311 is fixedly mounted on the machine base 11. The feeding seat 312 is slidably connected to the upper end of the feeding frame 311 via a guide rod slider structure. The feeding seat 312 is equipped with an air blowing assembly 33, which typically includes a hot air blower for heating and driving the airflow, a conveying hose, and a heating core fixed to the feeding seat 312. Both ends are connected to the output end of the hot air blower and the heating core, respectively. The barrel is inserted into the heating core and is securely locked onto the loading seat 312 by the positioning pin of the loading seat 312. The hot air output hose of the hot air blower is delivered to the heating core and blown into the barrel through several air holes on the heating core to remove debris and impurities from the barrel. The loading drive component 313 is preferably a cylinder, which is fixedly installed on the loading frame 311 and is used to drive the loading seat 312 to slide horizontally back and forth, so that the loading seat 312 drives the barrel to be transported to a position close to the heating component 34 for loading.

[0088] The transfer assembly 32 includes a transfer frame 321, a transfer mechanism 322, and a first transfer drive component 323. The transfer frame 321 is fixedly mounted on the base 11. The transfer mechanism 322 includes a transfer slide plate 3221, a transfer clamp 3222, and a second transfer drive component 3223. The transfer slide plate 3221 is slidably connected to the side of the transfer frame 321 via a guide rail slider structure. The transfer clamp 3222 is slidably connected to the side of the transfer slide plate 3221 opposite to the transfer frame 321 via the guide rail slider structure, and its sliding direction is perpendicular to the sliding direction of the transfer slide plate 3221. The second transfer drive component 3223 is fixedly mounted on the transfer slide plate 322. At the end of 1, its output end is used to drive the transfer clamp 3222 to slide horizontally. The transfer drive component 323 is fixedly installed on the base 11, and its output end is used to drive the transfer slide plate 3221 to move up and down, so that the transfer clamp 3222 can move in two mutually perpendicular directions. The transfer clamp 3222 grabs the barrel conveyed by the feeding component 31 from the lower clamping end and places it in the heating component 34. The heating component 34 is existing technology and will not be described in detail here. Generally, it is a heating device that heats air. The barrel is inserted into the heating pipe connected to the heating device. The heating hole of the heating pipe blows hot air outward to heat the inside of the barrel.

[0089] The base 11 is equipped with a temperature detection device 13 and a smoke exhaust device. The detection end of the temperature detection device 13 faces the heating component 34 and is used to monitor the temperature change during the barrel heating process in real time. The smoke exhaust device faces the heating component 34 and is used to suck up and exhaust the smoke generated during the barrel heating process.

[0090] See Figure 5The first assembly device 4 is located at the second work station and includes an assembly slide plate 41, a barrel assembly assembly 42, and an assembly drive unit 44. The assembly slide plate 41 is slidably connected to the frame 12 via a guide rail slider structure. The assembly drive unit 44 is fixedly installed on the assembly slide plate 41, and its output end is connected to the frame 12. It uses reaction force to drive the assembly slide plate 41 to move synchronously. The barrel assembly assembly 42 includes an assembly frame 421, an assembly motor 422, an assembly fixture 423, and a buffer pressure head 424. The assembly frame 421 is slidably connected to the assembly slide plate 41 via a guide rod structure, and its sliding direction is perpendicular to the sliding direction of the assembly slide plate 41. The assembly fixture 423 and the buffer pressure head 424 are both mounted on the assembly slide plate 421. The assembly motor 422 is fixedly mounted on the assembly slide plate 41 at the lower end of the assembly frame 421. Its output end is used to drive the assembly frame 421 to move up and down, so that the assembly fixture 423 and the buffer head 424 can move in coordination in two mutually perpendicular directions. The assembly fixture 423 can clamp the heated and expanded barrel and heat fit it to the stator and coil on the material carrier 221. In this embodiment, the buffer head 424 is slidably connected to the assembly frame 421. When a spring is connected between the buffer head 424 and the assembly frame 421, the buffer head 424 presses against the end of the barrel.

[0097] After being flipped, the barrel returns to the first station. The rotor and rear cover are loaded into the barrel manually or by a robotic arm. The barrel then enters the second rotation of the transfer table 21. At the same time, the barrel is loaded into the next process, and the next stator and coil are placed into the idle material carrier 221. The next barrel is placed into the upper material carrier 312.

[0098] The first assembly device 4 also includes a rear cover pressing assembly 43. The rear cover pressing assembly 43 includes a pressing frame 431, a pressing motor 432, an assembly pressing head 433, and a fixed shaft structure 434.

[0099] When the barrel with the front cover bolted on passes the second station twice along with the material carrier 223, the lower end of the fixed shaft slide rod 4341 is exposed in the assembly pressure head 433. It is aligned with and presses down on the rotor shaft. The shaft is engaged with the front cover. After the shaft is installed in place, the fixed shaft drive 4342 drives the fixed shaft slide rod 4341 to retract until it is completely retracted to the assembly pressure head 433. During this process, the assembly pressure head 433 continues to descend until it presses against the rear cover, pressing and positioning the rear cover with the barrel.

[0100] See Figure 2 and Figure 7 The rear cover connecting device 8 is located at the sixth station, between the first assembly device 4 and the second assembly device 9. The rear cover connecting device 8 includes a second connecting frame, a second connecting seat, a rear cover screw assembly, and a connecting drive component. The overall structure and operating principle of the rear cover connecting device 8 shown in this embodiment are basically the same as those of the front cover connecting device 6, and will not be described in detail here.

[0101] See Figure 9 The second assembly device 9 is located at the seventh station. It includes a frame 91, an assembly slide plate 92, a fan blade feeding assembly 93, a fan blade assembly assembly 94, and an assembly drive unit 95. The frame 91 is fixedly mounted on the base 11.

The mandrel 944 is provided with an elastic element, with its two ends connected to the feeding clamp 943 and the mandrel 944 respectively. The elastic force of the elastic element has a tendency to push the mandrel 944 outward, so that the lower end of the mandrel 944 protrudes from the feeding clamp 943. The assembly motor 942 is installed... On the assembly slide plate 2 92, the drive assembly frame 2 941 moves up and down. The mandrel 944 is aligned with the feeding bar 9332. The mandrel 944 is inserted into the shaft hole of the fan blade. Based on the matching size of the mandrel 944 with the shaft hole of the fan blade, the fan blade is snapped onto the mandrel 944. Then, the mandrel 944 is moved closer to the rotating shaft of the stator. During the process of the mandrel 944 contacting the rotating shaft, the spring is compressed and it retracts into the unloading clamp 943. The unloading clamp 943 then pushes the fan blade out and puts it on the rotating shaft. After it is put in place, the unloading clamp 943 clamps the entire barrel. The unloading fixture 10 is installed on the machine base 11. The unloading clamp 943 moves the barrel to the unloading fixture 10, and then the robotic arm device takes it out and collects it, realizing the unloading of the workpiece.

[0103] The specific work process of this plan is as follows:

[0104] This technical solution uses a conveyor device 2 to connect various workstations to form a circular production line. In the initial first workstation, workpieces are loaded manually or by a robotic arm onto the conveyor device 2, along with the stator and coil assembly and the oil seal and front cover assembly. The barrel is then loaded onto the heating supply device 3, which heats the barrel. In the second workstation, the first assembly device 4 picks up the heated and expanded barrel, transfers it, and heat-fits it onto the stator and coil. Simultaneously, the first assembly device 4 also performs a pressing operation between the rotor shaft, the rear cover, and the barrel from the previous process. In the third workstation, the front cover mounting device 5 picks up the oil seal and front cover assembly, transfers it, and presses it onto the barrel. In the fourth workstation, the front cover connecting device 6 bolts the front cover onto the barrel. In the fifth station, the flipping device 7 grabs the barrel and rotates it in the air at a specific angle (180 degrees) so that the front cover of the barrel is placed back with its orientation downwards. It then returns to the first station, where the rotor and rear cover are installed on the barrel, and the workpiece loading process in the next step is executed. In the second station, the first assembly device 4 presses the rotor shaft, rear cover, and barrel together. In the sixth station, the rear cover connecting device 8 bolts the rear cover onto the barrel. In the seventh station, the second assembly device 9 grabs the fan blade and mounts it onto the rotor shaft. After assembly, it grabs the barrel for unloading. The entire process, through the orderly spatial layout and precise temporal coordination of the various devices, achieves automated assembly line operation from parts to finished products, improving product production efficiency.
