Abstract
The invention discloses a motor packaging method, and the method comprises the steps: enabling an air bag to extend into an inner hole of a stator of a motor, and enabling the outer wall of the air bag to be closely attached to the peripheral wall of the inner hole of the stator; and enabling epoxy resin not to flow to the wall of the inner hole of the stator during the glue injection packaging of the motor.
Description
Technical field
The present invention relates to a kind of method for packing of motor.
Background technology
In the production process of motor, need to carry out injecting glue encapsulation to motor, concrete, first motor stator is assembled in motor housing, then circuit board is assemblied on an end face of motor stator, then toward the two ends infusion epoxy resin of motor housing, make epoxy resin cover the other end of circuit board and the motor stator be positioned on an end face of motor stator, epoxy resin plays the effect of insulation and waterproof to motor stator and circuit board.But when the two ends infusion epoxy resin of past motor housing, then the hole wall that epoxy resin is easy to the stator inner hole flowing to motor stator solidifies, like this, be assembled to by rotor after in stator inner hole, when machine operation, rotor rotates in stator inner hole high speed, rotor easily touches the epoxy resin be positioned on the hole wall of stator inner hole, like this, epoxy resin will hinder the normal rotation of rotor, from the normal work affecting motor.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of method for packing of motor, and it makes when carrying out injecting glue encapsulation to motor, and epoxy resin can not flow on the hole wall of stator inner hole.
For solving the problems of the technologies described above, the method for packing of motor provided by the invention, comprises the following steps:
Step one, be assemblied in motor housing by motor stator, motor stator has the first end face, the second end face and stator inner hole, is assemblied in by circuit board on the first end face of motor stator;
Step 2, extend in stator inner hole by an air bag, this air bag can launch to become cylindric in the deflated condition, and air bag diameter is in the deflated condition greater than the aperture of stator inner hole, and air bag axial length is in the deflated condition greater than the axial length of motor housing;
Step 3, inflated air bag by an electric air pump, airbag deployment, the outer wall of air bag and the perisporium of stator inner hole are close to;
The two ends infusion epoxy resin of step 4, past motor housing, makes the second end face of epoxy resin covering board, motor stator;
Step 5, bled to air bag by electric air pump, air bag draws in, is then taken out from stator inner hole by air bag, namely completes the encapsulation to motor.
As preferably, described air bag is greater than the aperture 10-20 millimeter of stator inner hole launching external diameter when becoming cylindric.
As preferably, baroceptor is provided with in described air bag, baroceptor is electrically connected with the input of a controller, the output of controller is electrically connected with electric air pump, when electric air pump is inflated air bag, if baroceptor detects that the air pressure in air bag reaches A, then controller control electric air pump quits work, wherein 2bar<A<4bar.
After adopting above structure, the present invention compared with prior art, has following advantage:
In the present invention, before the two ends infusion epoxy resin toward motor housing, one air bag is extend in stator inner hole, and air bag is inflated, make airbag deployment, the outer wall of air bag and the perisporium of stator inner hole are close to, now toward the two ends infusion epoxy resin of motor housing, epoxy resin is subject to the stop of the outer wall of air bag and cannot flows on the hole wall of stator inner hole, like this, rotor is being assembled to after in stator inner hole, when machine operation, make rotor can normal rotation, ensure that the normal work of motor.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
The method for packing of motor of the present invention, comprises the following steps:
Step one, with reference to figure 1, be assemblied in by motor stator 2 in motor housing 1, motor stator 2 has the first end face 201, second end face 202 and stator inner hole 203, is assemblied in by circuit board 3 on first end face of motor stator;
Step 2, with reference to figure 2, one air bag 4 is extend in stator inner hole, this air bag can launch to become cylindric in the deflated condition, and air bag diameter is in the deflated condition greater than the aperture of stator inner hole, and air bag axial length is in the deflated condition greater than the axial length of motor housing;
Step 3, with reference to figure 3, inflated, airbag deployment by an electric air pump to air bag 4, the outer wall of air bag and the perisporium of stator inner hole are close to;
Step 4, with reference to figure 4, toward the two ends infusion epoxy resin 5 of motor housing 1, make the second end face 202 of epoxy resin 5 covering board 3, motor stator 2;
Step 5, with reference to figure 5, bled to air bag by electric air pump, air bag draws in, then air bag is taken out from stator inner hole, namely completing the encapsulation to motor, and then follow-up assembling is carried out to motor, closing as rotor being assembled in stator inner hole, by motor housing.
Described air bag is greater than 15 millimeters, the aperture of stator inner hole launching external diameter when becoming cylindric, like this, when making airbag deployment inflating air bag, the outer wall of air bag can fit tightly with the hole wall of stator inner hole, to ensure not stay gap between the outer wall of air bag and the hole wall of stator inner hole, and, air bag is slightly bigger launching external diameter when becoming cylindric than the aperture of stator inner hole, make air bag to be launched completely required aeration quantity less, make the time needed for inflating air bag shorter, accelerate operating efficiency.
With reference to figure 2, Fig. 3, and Fig. 5, be provided with baroceptor 401 in described air bag, baroceptor is connected with the input wireless telecommunications of a controller, and the output of controller is electrically connected with electric air pump, when electric air pump is inflated air bag, if baroceptor detects that the air pressure in air bag reaches 3bar, then controller control electric air pump quits work, like this, situation air bag being exploded owing to excessively inflating air bag can be avoided to occur, to ensure processing safety.
Below only apply preferably example with regard to the present invention and made explanation, but can not be interpreted as it is limitations on claims, structure of the present invention can have other to change, and is not limited to said structure.In a word, all various changes done in the protection range of independent claims of the present invention are all in protection scope of the present invention.
