Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor stator production, in particular to a multi-head automatic winding machine for flat copper wire motor stators. BACKGROUND

[0002] The stator is the stationary part of the motor (electric motor or generator), which complements the rotor (rotating part) to form the core of the motor for realizing the conversion of mechanical and electrical energy. The stator is mainly composed of a stator core and a stator winding. During the production of the stator, copper wire needs to be wound on the core, which requires the use of a stator winding machine. In simple terms, a stator winding machine is an automatic or semi-automatic mechanical device that winds copper wire into the slot of the motor stator core according to a specific rule and number of turns. The commonly used copper wire is a copper wire with a circular cross-section. With the development, many stators now use copper wire with a rectangular cross-section, i.e. flat copper wire. This is because the rectangular cross-section of the flat copper wire can be tightly combined like bricks, greatly reducing the gap and greatly improving the slot fill rate. The current stator winding machine has a high degree of automation. For example, a Chinese invention patent with the authorization announcement number CN113746289A provides a stator winding machine, which discloses a stator winding machine including a clamping mechanism, a winding mechanism, and a robot hand. The clamping mechanism fixes the stator. The winding mechanism includes a mounting plate, a guide rail on the mounting plate extending along the axial direction of the stator, a lead assembly slidingly connected to the guide rail for pulling the wire along the winding column, a first drive assembly on the mounting plate driving the lead assembly to slide on the guide rail, a second drive assembly driving the mounting plate to move in a direction perpendicular to the guide rail, and a robot hand capable of pulling the wire to move, with two robot hands, i.e. a first robot hand and a second robot hand. However, the current automatic winding machine for flat copper wire motor stators has the following defects:

[0003] In order to improve the efficiency of winding operation, the current machine adopts a multi-head structure, i.e. a multi-station structure, which can simultaneously perform winding operation on multiple stators. However, correspondingly, multiple stator core clamping operations are required when winding is completed and when winding starts, which reduces the overall winding efficiency of the equipment.

[0004] Currently, different height requirements are needed when loading tobacco leaves in a tobacco curing barn, i.e. the tobacco leaves are at different height positions, which improves the space utilization rate of the curing barn. Therefore, the operator needs to constantly change positions and climb high when loading tobacco leaves, which is physically strenuous.

[0005] Therefore, we propose a multi-head automatic winding machine for flat copper wire motor stators to solve the above problems. SUMMARY

A plurality of second positioning blocks 183 are inserted into a plurality of second positioning ports 157 on another workpiece mounting structure 15. The first locking assembly 17 and the second locking assembly 18 are used to assist in fixing the positions of the two workpiece mounting structures 15.

[0046] Before use, the present invention requires the installation of corresponding clamps on the surface of the clamping carrier plate 152 to facilitate the clamping of different types of stator cores. During use, the copper wire winding operation unit 3 performs wire winding operations on the stator core mounted on the workpiece mounting structure 15 near the frame 2. At the same time, a robot arm clamps a stator core on another workpiece mounting structure 15. After the wire winding operation is completed, the two workpiece mounting structures 15 exchange positions. When exchanging positions, the first positioning block 173 in the first locking assembly 17 retracts into the first sliding opening 171, and the second positioning block 183 in the second locking assembly 18 retracts into the second sliding opening 181. The workpiece mounting structure 15 between the two vertical plates 110 first descends to the lowest position, and then the first servo reduction motor 118 starts. In this way, the two workpiece mounting structures 15 move in opposite directions in the horizontal direction until their positions are exchanged. After that, the workpiece mounting structure 15 between the two vertical plates 110 is raised to the highest position, and then the first positioning block 173 in the first locking assembly 17 returns to its original position, and the second positioning block 183 in the second locking assembly 18 retracts into its original position. Block 183 returns to its original position, and the winding operation continues. Clamping is performed on the workpiece mounting structure 15 located away from the copper wire winding operation section 3, thus continuously performing the winding operation. During the winding operation, the drive block 162 in the drive structure 16 can dock with the workpiece mounting structure 15 located at the copper wire winding operation section 3, driving multiple clamping carrier plates 152 to rotate and adjust their positions, facilitating the winding operation in conjunction with the copper wire winding operation section 3. In the worktable mechanism 1, one of the workpiece mounting structures 15 can slide vertically between two vertical plates 110, and the two workpiece mounting structures 15 can move horizontally, allowing them to exchange positions. Thus, while one workpiece mounting structure 15 is performing the winding operation at the copper wire winding operation section 3, a stator core workpiece can be clamped on the other workpiece mounting structure 15. After the winding operation is completed, the two workpiece mounting structures 15 quickly exchange positions and continue the winding operation. In this way, the winding operation and clamping operation can be performed simultaneously, improving the overall winding efficiency of the equipment.
