Problems solved by technology

[0002] The connection method between the motor steering gear and the motor coil, in the traditional production process, usually uses manual welding, such as placing a tin bar between the motor wire steering gear and the motor coil, using a welding torch to melt the tin bar at high temperature instantly, and the melted tin The motor steering gear and the motor coil are bonded together. In actual production, the purpose of connecting the motor steering gear and the motor coil is often achieved by spot welding. However, this welding method can only connect the outer side of the motor wire steering gear and the motor coil. If the peripheral connection is carried out, the inside of the motor wire steering gear and the motor coil cannot be welded, so the connection strength between the motor wire steering gear and the motor coil is not high, which cannot meet the demand for high connection strength. At the same time, the number of spot welding is determined by the motor wire. The circumference of the steering gear is determined, that is, a spot welding action needs to be repeated many times to complete the connection between a motor coil pad and a motor coil. The process takes a long time, and the adhesion of each solder joint is different, resulting in unstable quality after welding. low production rate, and the welding production environment is harmful to the operator's body

Embodiment 1

[0045] see Figure 1 to Figure 4 , a welding process method of a motor steering gear and a motor coil of the present invention, comprising the following steps:

[0046] Step (1): Apply adhesive

[0047] Coating the adhesive 2 on one side of the motor steering gear 1 for laminating the motor coil 3;

[0048] The coating amount of the adhesive is 0.1-0.3 mg.

[0049] The adhesive is grease paste.

[0050] Specifically, in this embodiment, the motor steering gear 1 is a ceramic substrate, and the adhesive 2 is a grease paste. An automatic placement machine is used to apply the adhesive 2 to the upper surface 11 of the motor steering gear 1. Adhesives 2 are equidistantly placed on the upper surface 11, wherein each portion of adhesive 2 is 0.2 mg.

[0051] Step (2): Secure the Motor Steering Gear

[0052] Use the fixture seat 4 to fix the motor steering gear 1 coated with the adhesive 2, so that the end coated with the adhesive 2 faces upward;

[0053] The fixture seat 4 is ...

Embodiment 2

[0079] The difference between the present embodiment and the first embodiment is that the motor product processed under the conditions of the present embodiment is suitable for motor products requiring low adhesion between the motor steering gear 1 and the motor coil 3 .

[0080] In step (1), the coating amount of adhesive 2 is 0.12 mg.

[0081] In step (4), the fixture seat 4 is heated, and when the temperature of the joint between the motor steering gear 1 and the motor coil 3 reaches 350 degrees Celsius, pressure is applied to the insulating member 5 .

[0082] In step (5), the force of the external force 6 is 55 Newtons, and the pressing time is 4 seconds.

[0083] The rest of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

Embodiment 3

[0085] The difference between the present embodiment and the first embodiment is that the motor product processed under the conditions of the present embodiment is suitable for the motor product that requires high adhesion between the motor steering gear 1 and the motor coil 3 .

[0086] In step (1), the coating amount of adhesive 2 is 0.25 mg.

[0087] In step (4), the fixture seat 4 is heated, and when the temperature of the joint between the motor steering gear 1 and the motor coil 3 reaches 380 degrees Celsius, pressure is applied to the insulating member 5 .

[0088] In step (5), the force of the external force 6 is 90 Newtons, and the pressing time is 4 seconds.

[0089] The rest of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.
