Problems solved by technology

[0003] The invention aims at the uneven distribution of the glue on the surface of the winding cup and the generation of glue spots on the surface easily caused by the conventional glue brushing or dipping process, and the uniformity of the filling of the glue inside and on the surface of the winding cup and the consistency of the size of the winding cup cannot be well controlled. To solve the shortcomings, a method is proposed to evenly fill the motor glue into the inside and surface of the winding cup by rolling and rolling

Embodiment Construction

[0012] The invention discloses a gluing method for the winding of a miniature hollow cup motor. Since the shape of the winding of the hollow cup motor is similar to that of a hollow water cup, rolling gluing is possible. see figure 2 The schematic diagram of gluing is shown, which includes the following steps: Step 1: Winding winding cup 1, preparing motor glue 2, and pouring it into the drip tube 3 (the motor glue can be 510A:510B glue according to 3: 1 proportioning); step 2: according to the inner diameter of the winding cup, select a mandrel 4 with an equivalent diameter, the diameter of the mandrel 4 is slightly smaller than the inner diameter of the winding cup, and put the winding cup on the mandrel; step 3 : Put the winding cup 1 that has been set on the mandrel on the roller shaft 5 of the rubber rolling machine to make it rotate and roll, and turn on the glue discharge system after 1 to 2 seconds, so that the dripping tube drops the motor glue on the surface of the ...

Abstract

The invention discloses a gluing method of a micro coreless cup motor winding, which comprises the following steps that: (1) a winding cup is wound, and motor glue is poured into a dripping hose; (2) a core rod with the diameter being equal to the inner diameter of the winding cup is selected, and the winding cup is wound on the core rod; (3) the winding cup which is sleeved on the core rod is put into a roll shaft of a glue rolling machine so that the winding cup rolls rotationally, a glue outlet system is started so that the dripping hose drips the motor glue onto the surface of the winding cup, and the roll shaft applies pressure onto the winding cup to uniformly distribute the motor glue inside and on the surface of the winding cup; and (4) the winding cup on which the glue is rolled is removed and put into an oven to be baked until the motor glue is fully cured. Motor glue is uniformly filled inside and on the surface of the hollow cup motor winding which is manufactured through the method, no glue blocks are left on the surface, the hardness and the strength are improved, the product pass rate is improved, and the load bearing capability and the working reliability of a motor are improved.

Description

technical field [0001] The invention relates to a manufacturing method of a motor winding, in particular to a gluing method for a miniature hollow cup motor winding. Background technique [0002] Miniature hollow cup motors are widely used in the miniature remote control toy industry due to the advantages of small size, large torque and high efficiency. However, for some occasions that require high power density, the high speed and high current of the motor may easily cause the temperature of the internal winding cup of the motor to rise, causing the winding cup to expand or loosen, resulting in the winding cup and the stator rubbing Touch, which will affect the normal operation of the motor, and even cause the motor to fail. In order to prevent the winding cup from loosening, it is usually glued to strengthen its strength. The existing gluing methods are divided into two types: brushing and dipping. figure 1 The dipping method is shown, but these two processes are likely...
