Working Principle of Stacked Slot Insulation Insertion Machine

The stacked slot insulation insertion machine is an automated equipment used in the manufacturing process of motor stators. It is mainly used to accurately and efficiently insert insulation paper (or insulation film) into the slots of the stator core. This step is a key link in motor manufacturing, which directly affects the insulation performance of the stator and the safe operation of the whole machine.

1. Introduction to the function of the equipment

In traditional manual operation, inserting insulation paper is a labor-intensive and high-precision job. The stacked slot insulation insertion machine realizes automatic cutting, forming, feeding and insertion of insulation paper through the cooperation of the automatic control system and the precision mechanical structure, which significantly improves production efficiency and consistency.

2. Main structural composition

A complete stacked slot insulation insertion machine is usually composed of the following key modules:

Insulation paper feeding system: Install insulation paper rolls or sheets, and the system has automatic paper feeding and positioning functions.

Paper cutting and forming device: Cut the insulation paper into corresponding shapes according to the size and shape of the stator slot, and bend or form it.

Insertion mechanism: The insulating paper is evenly inserted into each slot of the stator through a manipulator, a paper pushing mechanism or a mold.

Servo control system: PLC or industrial control system controls the action, rhythm and accuracy of the entire paper insertion process.

Detection and alarm device: Detect whether the paper is inserted in place, whether the paper is missing, etc. to ensure reliable operation.

3. Detailed explanation of working principle

Paper delivery and positioning: The insulating paper is sent to the cutting area by the paper feeding mechanism and accurately aligned by the positioning mechanism.

Automatic cutting and forming: According to the stator model and set parameters, the insulating paper of the corresponding size is automatically cut out, and the edges are bent to adapt to the slot structure.

Multi-slot synchronous insertion: The insertion head is usually designed with multiple channels, and the paper insertion action of multiple slots can be completed at one time. The paper insertion action is completed by a servo-driven insertion mold or manipulator with high action accuracy.

Cycle repetition: The equipment automatically repeats the paper insertion process according to the set beat until all slots are inserted.

Intelligent detection: During the insertion process, the equipped sensor or visual detection system can determine whether there is missing insertion, skewness or multiple insertion, and automatically alarm to prompt maintenance.

4. Application Advantages

The stacked slot insulation insertion machine has the characteristics of high efficiency, high consistency and low error rate, and is particularly suitable for the insulation treatment of stator coils of small motors, household appliance motors, automotive motors, etc. produced in batches. Compared with manual operation, its finished product qualification rate is higher, and its operation safety and beat stability are also better.

With the development of lightweight, miniaturization and high performance of motor products, modern stacked slot insulation insertion machines are also constantly upgraded, integrating more intelligent control, flexible production and data traceability functions, and becoming an important part of the motor automation production line.
