DETAILED DESCRIPTION

[0014] The utility model will be further explained in detail in combination with the drawings and specific embodiments. The embodiments of the utility model are given for example and description, and are not exhaustive or limit the utility model to the disclosed form. Many modifications and changes are obvious to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical application of the utility model, and enable those skilled in the art to understand the utility model so as to design various embodiments with various modifications suitable for specific purposes.

[0015] Please refer to Figs. 1-2 In the embodiment, a brushless motor stator automatic feeding and discharging winding machine is provided, which comprises a feeding equipment, and the feeding equipment comprises a storage disc assembly and a module assembly.

[0016] The storage tray assembly 6 is placed on the machine workbench, and its position is corrected by four edge limiting blocks. A cylinder assembly is arranged on one side of the tray to prevent loosening during winding and catching. The tray can be replaced when the cylinder assembly push rod is retracted before the production starts. When the preparation is ready to start production, the cylinder assembly push rod is retracted. The tray is composed of two parts and is placed in the direction required by the design. A plurality of stator setting columns are installed on the tray, and each stator column is provided with a positioning device to ensure that all stators are in the same direction and height before starting. The stator is placed on the tray by manual placement, and the catcher automatically grabs it to proceed with winding.

[0017] The Z-direction feeding module 8 is vertically movable and hard-linked to the bracket. The bracket is provided with the air claw 10. The air claw has two pairs, that is, two stators are taken and placed at a time, and four stators are taken and placed at a time. The claw palm core is designed with a clamping position for positioning the direction of the stator to prevent the stator from deviating during the grabbing and placing process, which may cause the stator to be unable to be placed for winding.

[0018] The box assembly 4 includes a driving motor, a winding spindle, a belt, and a synchronous wheel. The winding die assembly 5 is installed at the front end of the winding spindle, and the spindle is driven by the motor to realize four-axis synchronous rotation for winding. The box assembly is installed on a horizontal slide rail, and the slide rail is in the same direction as Y. The slide rail can realize forward and backward movement under the drive of the motor. Therefore, under this condition, the stator can be wound and arranged neatly and beautifully by relying on the driving motor.

[0019] The angle assembly 13 mainly functions to rotate the stator for winding. The angle power is driven by the motor belt to realize four-axis synchronous rotation of the angle shaft. The stator is placed on the stator rod of the angle shaft at a specified height relative to the winding die. When the stator is full in one slot during winding, the motor is rotated according to the program instruction of the equipment, so as to enter the next slot for winding. The main shaft of the angle assembly and the stator rod are designed to be hollow. A cylinder needle rod mechanism is designed at the lower end of the main shaft. After the stator is successfully placed, the cylinder automatically pushes the needle rod upward, and the needle tightly pushes the stator rod upward to fix the stator.

[0020] The brushless motor stator automatic feeding and winding machine also includes a scissors support assembly 1 for cutting the winding. Four scissors heads 9 are suspended and fixed on the scissors assembly cylinder support. The scissors support assembly can vertically displace the scissors heads downward under the action of the scissors cylinder 12. It is worth noting that the scissors heads 9 are designed with a cylinder connection to realize self-clamping and cutting functions. Please refer to the patent document of a motor winding machine scissors of our company. After winding is completed, the four scissors heads cut the copper wire. The installation position of the scissors heads 9 is provided with a U-shaped groove to facilitate the adaptation of winding equipment with different arrangement spacings, and the adjustable space is relatively large.

[0021] The working principle of the automatic feeding and discharging winding machine for the brushless motor stator is as follows: the storage plate 6 is placed by hand before starting production, and is fixed under the action of the cylinder after starting. At this time, the claw hand 10 is displaced to the upper side of the stator from the set origin under the linkage of the XY axis module 23 according to the program set in advance by the equipment. At this time, the Z axis module 9 is used to accurately grab the claw hand, and then the Z axis claw hand 10 lifts the stator upward to a safe height, and is displaced to the upper side of the winding stator rod in front of the die assembly 5 by the Y axis module 4, and then the Z axis module 8 places the stator downward to the stator rod, wherein the corner system 13 is used to lift the needle to fix the stator, and then the claw hand retreats to the safe area to wait, that is, the feeding of the stator in this round is completed. The stator in this round waits on the stator rod, and the die assembly 4 moves to a specified distance, at this time, the die tongue 5 in front of the die is also accurately adjusted in position by the cylinder, at this time, the winding spindle rotates to complete the winding of the single slot of the stator under the die and the flying fork, the corner assembly rotates the stator to be wound to the next slot of the die according to the set rotation angle, and so on, until the stator is wound, and then the scissors assembly 1 is used to push the scissors cylinder downward to make the scissors head 9 clamp and cut the copper wire, at this time, the claw hand 10 again goes to the stator that has been wound to place it back to the specified position of the material disc, which is the winding process of this example.

[0022] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, such as without special description and limitation, are implemented according to the conventional means in the art.
