Technical Field
[0001] This invention specifically relates to the field of dispensing and curing technology, and more specifically to an automatic dispensing and curing device for motor stators. Background Technology
[0002] With the continuous expansion of motor application scenarios, such as new energy vehicles and high-end industrial equipment, the performance requirements for motors are becoming increasingly stringent. Motor stators need to have good insulation, mechanical stability, and heat dissipation. Dispensing and curing can effectively fix the coils, preventing them from shifting due to vibration during motor operation, while also enhancing insulation performance, avoiding faults such as short circuits, and assisting in heat dissipation. In new energy vehicle motors, in order to ensure stable operation of the motor under complex working conditions, the dispensing and curing process of the stator coils requires the adhesive to have high insulation, high thermal conductivity, and resistance to high and low temperatures. Traditional motor stator dispensing processes are mostly manual, with workers using dispensing guns and relying on experience to apply glue. This method has many limitations. First, the precision and stability of manual operation are difficult to guarantee, easily leading to inconsistent glue application and dispensing position deviations, affecting motor quality and performance. Second, the glue flow rate cannot be accurately controlled, which may result in excessive glue filling the internal space of the stator or insufficient glue to effectively fix the insulation material, weakening the insulation effect. In addition, manual dispensing is inefficient and labor-intensive, making it difficult to meet the needs of large-scale industrial production. Currently, traditional motor stators are cured by dispensing adhesive and then naturally curing. However, this curing process is lengthy and susceptible to external environmental influences. Natural curing cannot effectively meet the work efficiency requirements for large-scale motor stator dispensing and curing. A search revealed that Chinese Patent Publication No. CN202221758739.5 discloses an automatic stator dispensing and curing device; it includes a base plate, a gantry frame, a dispensing and curing assembly, and a clamping assembly. The clamping assembly is installed in the middle of the base plate, the gantry frame is located above the clamping assembly, the dispensing and curing assembly is installed on one side of the gantry frame, and a slide rail is provided below the clamping assembly, the slide rail being perpendicular to the gantry frame. The device in the aforementioned patent achieves the dispensing effect on the motor stator by moving the dispensing head. However, in actual operation, the stator is ring-shaped, so the dispensing head or the stator needs to be able to rotate effectively during the dispensing process. Although the dispensing head in the aforementioned patent can move effectively, it can only achieve the effect of lateral movement and cannot effectively rotate along the top of the coil on the stator. This makes the aforementioned patent still have certain defects. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic dispensing and curing device for motor stators. In this device, the stator to be dispensed is placed in a placement cylinder on a turntable, effectively limiting and fixing the stator. The turntable rotates to sequentially transport the stator. First, the glue gun at the end of the robotic arm dispenses glue onto the stator. Switching between two glue guns effectively satisfies the dispensing effect at different angles on the stator. During the dispensing process, a first cylinder engages the drive gear on the output shaft of the rotating motor with the gear ring at the bottom of the placement cylinder, achieving the effect of stator rotation, thus effectively ensuring the dispensing quality and efficiency of the glue gun. After dispensing, the turntable rotates to transport the dispensed stator to the bottom of the heating coil, where heating achieves the effect of glue curing, effectively ensuring the quality of dispensing. After curing, the turntable transports the cured stator to the bottom of the leveling assembly, where a second cylinder uses a pressure plate to level the cured glue, preventing any omissions. This solves the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: An automatic dispensing and curing device for motor stators includes a base; a protective cover is fixedly installed on the top of the base; a dispensing assembly is provided inside the protective cover; the dispensing assembly includes a robotic arm; the bottom of the robotic arm is fixedly installed on a horizontal plate of the base; a first glue gun and a second glue gun are fitted at the end of the robotic arm; the first glue gun and the second glue gun are movably installed with the robotic arm via a rotating structure.

The pulley on the reducer extension shaft is connected to the drive pulley on the output shaft of the drive motor via a connecting belt. The drive motor is fixedly mounted on the bottom of the base's horizontal plate. As a further technical solution of the present invention, a drive assembly is provided between the horizontal plate of the base and the turntable; the drive assembly includes a first cylinder; a support frame is fixedly installed on the push rod of the first cylinder; a rotary motor is fixedly installed on the support frame; a drive gear is fixedly installed on the output shaft of the rotary motor; the drive gear meshes with the teeth inside the gear ring; the drive assembly is located on one side of the reducer.

As a further technical solution of the present invention, one end of the protective cover is open; the two sides of the protective cover are provided with symmetrical protective grilles; a controller is fixedly installed between one of the protective grilles and the protective cover; and a placement plate is fixedly installed at the end of the base. Compared with the prior art, the beneficial effects of the present invention are: In this invention, the motor stators arranged on the placement plate are placed in a placement cylinder near the placement plate. The placement cylinder effectively limits and fixes the motor stators during dispensing. The drive motor drives the turntable to rotate via a drive pulley and connecting belt, achieving the effect of sequential transmission of the motor stators. The placement cylinder containing the motor stators first rotates to the top of the drive assembly for dispensing. During dispensing, a robotic arm drives the first and second glue guns, ensuring that the glue guns contact the coils on the stator, thereby guaranteeing the quality of dispensing. By switching between the two glue guns, the dispensing needs of different angles of the stator can be effectively met during dispensing. In this invention, during the dispensing process, the first cylinder drives the rotary motor to move upward through the support frame, so that the drive gear on the output shaft of the rotary motor meshes with the gear ring at the bottom of the placement cylinder. The drive motor effectively drives the placement cylinder and the motor stator to rotate, thereby ensuring that the glue gun can effectively dispense glue to the coil at the end of the stator. In this invention, after dispensing, the first cylinder lowers the drive gear and separates from the gear ring. The reducer rotates the turntable, transferring the dispensed motor stator to the curing assembly. First, a rotary cylinder drives the mounting bracket to rotate 90°, rotating the heating coil to the top of the motor stator. Then, an electric pusher cylinder drives the lifting frame to effectively adjust the distance between the heating coil and the motor stator, ensuring effective heating and curing of the adhesive on the stator. After the heating coil is heated to a certain temperature, it is held for a period of time to ensure the quality of the dispensing curing. After curing, the rotary cylinder rotates the heating coil to one side of the turntable to avoid collisions between the stator and the heating coil during the transfer of the stator through the turntable. This invention, through the rotation of the turntable, effectively transfers the stator after the adhesive has been cured to the bottom of the leveling assembly. The second cylinder drives the pressure plate to contact the adhesive on the stator, thereby effectively flattening the adhesive surface and preventing unevenness between the coils and the adhesive on the stator. This effectively ensures the quality of the stator adhesive and the service life of the stator. Attached Figure Description
