Description

Technical Field

[0001] The invention relates to an armature electric heating paint dripping device, belonging to the technical field of flat wire motor armature insulation processing equipment. Background Art

[0002] The motor manufacturing industry has always been a labor-intensive industry. Due to the special nature of its products, it has not been possible to achieve automated production. The armature coil must be strictly coated with insulating varnish to avoid short circuits. The armature coating and varnish dripping are both done by semi-automatic machines or fully manual operations, and automated loading and unloading cannot be achieved. However, both semi-automatic and manual production costs are high, the labor intensity is high, the efficiency is low, and the quality cannot be effectively guaranteed, resulting in a low pass rate for finished products. With the current increase in labor costs and the widening gap in labor demand, it has become difficult to meet the needs of some motor manufacturers.

[0003] With the rapid development of the automotive industry and the increasing use of various electrical products in recent years, there is a growing demand for improved production and quality of motors. Armature coils are made by tightly winding enameled wire, then applying insulating resin varnish via a dripping process. At room temperature, insulating resin varnish has poor fluidity and therefore cannot penetrate the coils evenly, even within the narrow gaps. Traditional heating methods and manual or semi-automatic armature coating and dripping processes result in uneven armature heating and less than ideal dripping results. These methods no longer meet product efficiency and quality requirements. Market factors demand reduced labor costs and improved production efficiency, necessitating automated loading and unloading and improved quality of dripped insulation products. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and to provide an armature paint dripping device with a simple structure and electric heating control during the automatic dripping of insulating resin during the armature paint dripping production process, so as to solve the problems of uneven heating of the traditional armature and difficulty in achieving ideal paint dripping effects raised in the above-mentioned background technology, replace manual or semi-automatic grasping, ensure automatic loading and unloading, reduce the labor intensity of workers, achieve uniform penetration of armature insulating resin in paint dripping, improve the production efficiency of the armature end face insulation paint dripping process, ensure the automation of armature paint dripping, and improve product quality, production efficiency and safety.

[0005] The objectives of the present invention are achieved through the following technical solutions: an armature electrically heated paint-drip device comprises a bracket and a three-jaw clamping mechanism mounted on the bracket, the three-jaw clamping mechanism being equipped with a clamping mechanism and a rotational drive mechanism, a swinging drive mechanism being mounted on the bracket, a transverse movement mechanism and paint-drip mechanisms 1 and 2 being mounted above the three-jaw clamping mechanism, the three-jaw clamping mechanism being capable of uniform rotation and back-and-forth swinging after clamping the armature, and an electric heating mechanism being disposed directly behind the three-jaw clamping mechanism. After the armature is positioned and inserted by a robot or servo loading mechanism, the clamping mechanism resets the movable jaw within the three-jaw clamping mechanism to simultaneously clamp the armature with the two fixed jaws, and the electric heating mechanism moves an energized brush to connect a high-current power source to the armature, heating the coil and allowing the insulating paint to fully penetrate the coil. The rotary drive mechanism installed on the bracket drives the synchronous belt and the gear set to drive the clamping claw to clamp the armature to rotate at a constant speed. At the same time, the swing drive mechanism can drive the clamping claw to swing the armature back and forth, accurately locate and control the inclination angle of the armature, and automatically adjust the armature paint dripping position. During the rotation of the armature, the energized brush rotates synchronously with the armature, realizing the simultaneous dripping and impregnation of the inner and outer sides of both ends of the uniformly rotating armature, and is provided with an anti-drip tray and a receiving tray to collect dripping insulating resin paint.

[0006] Furthermore, there are three jaws installed on the rotating inner ring in the three-jaw clamping mechanism, including one movable jaw and two fixed jaws, which are evenly distributed axially along the central axis of the inner support clamp. As the rotating inner ring rotates at a uniform speed, the clamping mechanism controls the movable jaw to clamp and release the armature.

[0007] Furthermore, the electric heating mechanism moves back and forth on the guide rod, and the energized brushes are in contact with the three-phase line electrodes of the armature to supply high current power to the armature. The energized brushes are driven by the rotating drive mechanism and rotate synchronously with the armature, thereby realizing continuous energized heating of the uniformly rotating armature.

[0008] Furthermore, the paint dripping system includes a transverse movement mechanism and a paint dripping mechanism arranged on a fixed frame, and a paint dripping nozzle arranged on the paint dripping mechanism, and the paint dripping mechanism can drive the paint dripping nozzle to move horizontally and vertically.

[0009] Compared with the prior art, the effects and benefits of the present invention are as follows: (1) The armature electric heating paint dripping device adopts a three-claw clamping mechanism to fix the armature, ensuring the automated operation of the armature parts by the manipulator, and accurately positioning and controlling the uniform rotation and forward and backward swing angle of the armature through the rotary drive mechanism and the swing drive mechanism, and can automatically adjust the armature paint dripping position, realizing the simultaneous paint dripping operation on the inner and outer sides of the armature from multiple angles, effectively solving the problem of the quality of armature paint dripping and dipping caused by the insulating paint with fluidity deviation that cannot fully penetrate into the inner side of the winding, the core slot, the slot insulation, and the slot wedge. (2) The energized brushes of the electric heating mechanism contact the three-phase wire electrodes of the armature to supply high current power to the armature, and can rotate synchronously with the armature, so that when the armature rotates, the copper wire of the armature is in a heated state, so that the insulating paint can fully penetrate into the coil, reducing the amount of paint dripping, reducing the cost of varnish dipping and the amount of waste paint to be processed; (3) During the paint dripping process, the heating temperature controlled for different copper wires is different, ensuring that the armature is continuously heated while ensuring that the temperature of each armature is relatively balanced when dripping paint; the electric heating mechanism realizes the power supply heating of the copper wire of the armature, so that the armature no longer needs to be cooled subsequently, thereby improving work efficiency and product quality.
