Description

Technical Field

[0001] This application relates to the technical field of motor assembly, and particularly to an automatic motor assembly device. Background Art

[0002] Automatic motor assembly refers to the process of using automated equipment and technologies to efficiently and precisely assemble various components of a motor (such as a stator, rotor, end cap, bearings, etc.) into a complete motor according to a specific process flow. In the early days of motor production, manual assembly was mainly relied on, and there were many problems with manual assembly. For example, the assembly efficiency was low. It might take several hours for a skilled worker to assemble an ordinary motor, and as the motor structure became more and more complex, the assembly time would be even longer.

[0003] In the prior art, for the related technologies of automatic motor assembly, reference can be made to a Chinese patent with the publication number CN117220460A, which discloses a motor production line including a stator assembly line. The stator assembly line includes multiple assembly machines; the stator assembly line also includes several transfer devices. A transfer device includes a front support seat configured on the previous assembly machine and a rear support seat configured on the next assembly machine. The front support seat and the rear support seat are used to support the stator, and the stator stands upright with its opening arranged horizontally; the transfer device also includes a transfer mechanism. The transfer mechanism includes a clamping component for clamping the stator, and the clamping component can lift and translate to transfer the stator from the front support seat to the rear support seat. Or, the transfer mechanism includes a positioning member that can lift and translate. The positioning member has an upward concave portion that opens downward, and the top of the stator is accommodated in the upward concave portion to position and move the stator. This solves the problem of being able to reduce manual loading and unloading operations, enabling each assembly machine to work continuously and improving production efficiency.

[0004] The inventors found the following problems in the prior art during the implementation of this application:

[0005] A motor mainly consists of a housing, a rotor, and a rubber cover. Currently, in order to improve the efficiency of motor assembly, different automatic assembly stations are usually set up. And the rotor and the rubber cover need to be assembled into the housing in sequence. Currently, the assembly equipment is usually two different types. After the rotor assembly is completed, it is necessary to use a manipulator to move the housing with the rotor to the next station, which takes extra time, thus affecting the overall assembly efficiency and automation level. Summary of the Invention

[0006] The purpose of this application is to provide an automatic motor assembly device.

[0007] An automatic motor assembly device provided by this application adopts the following technical solutions:

[0008] An automatic motor assembly device includes a production platform, a casing flipping station, a rubber cover feeding station, and a shielding ring rotating station. A casing feeding station is arranged on the side of the production platform. A first feeding table is arranged above the production platform. A moving table is arranged on the side of the first feeding table away from the casing feeding station. A casing flipping station is arranged at the edge of the production platform. A rotor feeding station is arranged on the side of the casing flipping station away from the casing feeding station. A rubber cover feeding station is arranged on the side of the rotor feeding station away from the casing flipping station. A first casing conveying station is arranged on the side of the moving table away from the rubber cover feeding station. A second casing conveying station is arranged on the side of the first casing conveying station away from the casing feeding station.

A shielding ring rotating station is arranged on the side of the performance testing station away from the knocking station. A shielding ring installation station is arranged on the side of the shielding ring rotating station away from the performance testing station.

[0009] By adopting the above technical solutions, the production platform serves as the hub of the entire device to cooperate with the orderly operation of each station. The casing flipping station is used to flip the casing cylinder by 180°. Then, the rotor feeding station accurately places the rotor into the inside of the casing cylinder. Adjacent to the rotor feeding station is the rubber cover feeding station, which accurately conveys the rubber cover to the position to be assembled through an automated conveying system, preparing for the subsequent pressing process. The first casing conveying station conveys the casing with some components assembled to the next process. Immediately afterwards, the second casing conveying station further undertakes the conveying task of the casing cylinder to ensure the continuous conveyance of the casing cylinder in the assembly process. The rubber cover pressing station precisely presses the rubber cover onto the casing cylinder to ensure the tightness and stability of the assembly. The provided rubber cover feeding station continuously supplies sufficient rubber covers to the rubber cover pressing station. Then, the knocking station uses a knocking structure to moderately knock the assembled components to make the connection between the components more stable. After the detection is completed, the performance testing station comprehensively tests various performance indicators of the assembled casing cylinder. The shielding ring rotating station precisely rotates and adjusts the shielding ring to prepare for the subsequent installation process. Then, the shielding ring installation station installs the shielding ring onto the motor cylinder to complete the assembly of the rotor, rubber cover, and shielding ring of the motor. Through the high coordination of each station, this automatic motor assembly device realizes the automated assembly line operation of motor assembly, which not only greatly reduces manual intervention, lowers the labor intensity, but also significantly improves the production efficiency and product consistency, having extremely high practical value and remarkable economic benefits.

[0010] The casing loading station includes a conveying table, a first feeding port, a first electric push rod, a second electric push rod, and a discharging port. A first feeding port is provided on one side of the conveying table away from the production platform. A first electric push rod is provided at the edge of the conveying table. A second electric push rod is provided on one side of the conveying table away from the first electric push rod. A discharging port is provided on one side of the conveying table away from the second electric push rod.

[0011] By adopting the above technical solution, the casing cylinder enters the conveying table from the first feeding port. The first electric push rod and the second electric push rod precisely adjust the position of the casing on the conveying table according to a preset program. These two electric push rods drive a lead screw nut mechanism through a motor to convert the rotational motion of the motor into a linear motion, thereby pushing the casing cylinder to move on the conveying table. After being pushed by the second electric push rod, the casing cylinder is pushed from the discharging port to the production platform, ensuring that the casing cylinder continuously enters the first loading table of the production platform.

[0012] The casing flipping station includes a sliding base, a first clamping and translating station, a second clamping and translating station, a third clamping and translating station, and a flipping assembly. A first clamping and translating station is slidably connected to the edge of the sliding base. A second clamping and translating station is provided on the side of the first clamping and translating station. A third clamping and translating station is provided on one side of the second clamping and translating station away from the first clamping and translating station. A flipping assembly is provided below the second clamping and translating station. The flipping assembly includes a clamping claw, a rotating shaft, and a docking base. A rotating shaft is rotatably connected to the side of the clamping claw away from the production platform. A docking base is provided on the side of the rotating shaft away from the clamping claw.

[0013] By adopting the above technical solution, the three clamping and translating stations drive ball screws through servo motors to achieve precise linear movement and positioning. They cooperate to precisely grasp the casing cylinder and transfer it to a suitable position. When the casing is moved above the flipping assembly, the clamping claw is connected to an electric drive structure through the rotating shaft to achieve rotational connection, and the clamping claw is driven to clamp the casing cylinder. The rotating shaft is connected to a rotary drive structure inside the docking base. Driven by the motor, the rotating shaft rotates, thereby realizing a 180° rotation of the casing cylinder to meet the requirements of the subsequent assembly process for the direction of the casing cylinder.

[0014] The first casing conveying station includes a slide rail, a mounting seat, a moving workpiece, a connecting plate, and a moving claw. A mounting seat is slidably connected above the slide rail. A moving workpiece is slidably connected to the side of the mounting seat. A connecting plate is bolted to the top of the moving workpiece. A moving claw is provided on the side of the connecting plate away from the moving workpiece.

[0015] By adopting the above technical solution, the mounting base moves on the slide rail through the meshing of the gear connected to the motor and the rack on the slide rail. The moving workpiece moves on the mounting base through the meshing of another set of motors using gears and racks to drive the rod of the moving workpiece to move, achieving side sliding. Then, the moving claw realizes the clamping effect through electric drive and grabs the casing barrel with the assembled rotor for movement, so that the casing barrel is transported along the slide rail to the next process.

[0016] The rubber cover feeding station includes a rubber cover conveying channel, a second loading table, a second feeding port, and a camera. A second loading table is arranged on the side of the rubber cover conveying channel. A second feeding port is arranged on the side of the second loading table away from the rubber cover conveying channel. The camera is installed above the rubber cover conveying channel through bolts.

[0017] By adopting the above technical solution, the rubber cover enters from the second feeding port, reaches the rubber cover conveying channel through the second loading table. The camera detects the electronic components in the rubber cover through image recognition technology. By transmitting the collected image information to the control system, the control system analyzes the image through a preset algorithm to judge the position, quantity, quality, etc. of the electronic components. If it is found that there are differences in the positions of the electronic components, the control system will drive the rubber cover flipping unit to flip the rubber cover to achieve flatness of the rubber cover. At the same time, the camera can also monitor the conveying situation of the rubber cover in real time to ensure that the rubber cover can continuously provide sufficient materials for the rubber cover pressing station.

[0018] The knocking station includes a first electric push rod, a knocking channel, a second electric push rod, a first moving channel, a third electric push rod, and a second moving channel. The pushing end of the first electric push rod is placed with the knocking channel. A second electric push rod is arranged on the side of the knocking channel away from the first electric push rod. The pushing end of the second electric push rod is placed with the first moving channel. A third electric push rod is arranged on the side of the knocking channel away from the rubber cover feeding station. The output end of the third electric push rod is placed with the second moving channel.

[0019] By adopting the above technical solution, when the motor barrel assembled with the rotor and the rubber cover enters the knocking station, the first electric push rod pushes the motor barrel into the knocking channel. In the knocking channel, the motor is knocked in the second channel by the first electric push rod. After the knocking is completed, the second electric push rod pushes the motor barrel to the first moving channel, and then the third electric push rod pushes the motor to the second moving channel. While realizing the transfer of the motor barrel at the knocking station, it also moderately knocks the assembled components to make the connection between the components more stable and improve the position accuracy between the rotor, the rubber cover, and the casing.

[0020] A limiting workpiece is arranged below the rotor loading station. The limiting workpiece includes a limiting sleeve plate, a fixing block and a casing cylinder. A fixing block is arranged on one side of the limiting sleeve plate away from the moving table, and a casing cylinder is placed below the limiting sleeve plate. The rotor loading station includes a steering bracket, an electric telescopic rod and a rotor adsorption sleeve. An electric telescopic rod is installed at the edge of the steering bracket, and a rotor adsorption sleeve is installed at the bottom end of the electric telescopic rod. The rubber cover loading station includes a continuous feeding table and a feeding seat. The feeding seat is arranged on one side of the continuous feeding table away from the production platform.

[0021] By adopting the above technical solution, when the casing cylinder is conveyed below the rotor loading station, the limiting workpiece positions the position of the casing cylinder. Then when the casing moves below the limiting sleeve plate, the limiting sleeve plate connected to the fixing block restricts the position and posture of the casing cylinder. Then the steering bracket can adjust the angle through a rotary joint driven by a motor. The electric telescopic rod uses a motor-driven screw-nut mechanism to achieve telescopic movement. The electric telescopic rod drives the rotor adsorption sleeve to descend. The rotor adsorption sleeve accurately adsorbs the rotor into the interior of the rotor adsorption sleeve through electromagnetic adsorption, and then rises and places the rotor into the interior of the casing cylinder.

[0022] A sensor detection component is arranged between the rubber cover loading station and the rubber cover feeding station. The sensor detection component includes a fixing frame, a rotating base and a sensing detection probe. The rotating base is clamped inside the fixing frame, and a sensing detection probe is rotatably connected above the rotating base. The performance detection station includes a pre-rotation station, an no-load detection station and a withstand voltage detection station. The no-load detection station is arranged on one side of the pre-rotation station away from the casing loading station, and the withstand voltage detection station is arranged on one side of the no-load detection station away from the pre-rotation station.

[0023] By adopting the above technical solution, then when the casing cylinder moves, the sensor detection component, through the rotating base connected to the fixing frame, where the rotating base drives the sensing detection probe through a motor to move the passing casing cylinder, so as to detect the corresponding position of the moving casing cylinder. Then when the casing cylinder is below the pre-rotation station, the casing cylinder with the rotor installed is preliminarily operated by a frequency conversion motor to make the components of the motor enter the working state, and then enter the no-load detection station. In the no-load state, through the speed sensor, current sensor and voltage sensor inside the no-load detection station, the parameters of the speed, current and voltage of the motor are detected to judge whether the no-load performance of the motor meets the requirements. Finally, in the withstand voltage detection station, a withstand voltage test is carried out on the motor by the withstand voltage test station, applying a certain high voltage between the winding of the motor and the casing cylinder to detect the insulation performance of the motor, comprehensively detecting various performance indexes of the motor, and strictly controlling the product quality.

[0024] The shielding ring rotating station includes a first clamping station, a second clamping station, a third clamping station, a placement base, an infrared detection probe, a positioning plate, and a shielding ring loading base. The second clamping station is arranged on the side of the first clamping station, the third clamping station is arranged on the side of the second clamping station away from the first clamping station, the placement base is arranged below the first clamping station, the infrared detection probe is installed on the outer diameter surface of the placement base, the positioning plate is arranged below the second clamping station, and the shielding ring loading base is arranged below the third clamping station.

[0025] By adopting the above technical solution, the first clamping station, the second clamping station, and the third clamping station drive the screw rods driven by the servo motors to insert the clamping semi-rings into the shielding ring, and support the shielding ring through expansion, so as to accurately clamp and move the shielding ring. According to the position information fed back by the infrared detection probe and the positioning plate, the position of the shielding ring is accurately adjusted. Then, the infrared detection probe detects the position and attitude of the shielding ring by emitting and receiving infrared rays. While placing the shielding ring, the positioning plate provides an accurate positioning reference for the shielding ring by the infrared detection probe, preparing for subsequent installation.

[0026] The shielding ring installation station includes an installation bracket, an installation reinforcement bracket, and a limiting collar. The installation reinforcement bracket is arranged on the side of the installation bracket, and the limiting collar is arranged below the installation bracket.

[0027] By adopting the above technical solution, when the shielding ring is adjusted to the appropriate position, the installation bracket and the installation reinforcement bracket are driven by the motor to squeeze the shielding ring, so that the shielding ring is squeezed and installed on the casing cylinder. Then, the limiting collar accurately positions the shielding ring to ensure the stability and firmness of the shielding ring installation.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The production platform serves as the hub of the entire device to coordinate the orderly operation of each work station. The casing flipping work station is used to flip the casing cylinder by 180°. Then, the rotor feeding work station accurately places the rotor inside the casing cylinder. Adjacent to the rotor feeding work station is the rubber cover feeding work station. This work station uses an automated conveying system to precisely convey the rubber cover to the position to be assembled, preparing for the subsequent press-fitting process. The first casing conveying work station conveys the casing with some components already assembled to the next process. Immediately following, the second casing conveying work station further undertakes the conveying task of the casing cylinder to ensure the continuous conveyance of the casing cylinder during the assembly process. The rubber cover press-fitting work station precisely presses the rubber cover onto the casing cylinder to ensure the tightness and stability of the assembly. The provided rubber cover feeding work station continuously supplies an adequate number of rubber covers to the rubber cover press-fitting work station. Then, the tapping work station uses a tapping structure to moderately tap the assembled components to make the connection between the components more stable. After completion of the inspection, the performance inspection work station comprehensively inspects various performance indicators of the assembled casing cylinder. The shielding ring rotation work station precisely adjusts the rotation of the shielding ring to prepare for the subsequent installation process. Then, the shielding ring installation work station installs the shielding ring onto the motor cylinder to complete the assembly of the rotor, rubber cover, and shielding ring of the motor. Through the high coordination of each work station, this automatic motor assembly device realizes the automated assembly line operation of motor assembly. This not only greatly reduces manual intervention, lowers the labor intensity, but also significantly improves the production efficiency and product consistency, having extremely high practical value and remarkable economic benefits;
