[0072] As an optional embodiment of the present invention, the specifications, quantity and positions of the pressing blocks 22 located on both sides of the carrier assembly 4 are the same or different.

[0073] Furthermore, the downward pressing driving member, the pressing driving member and the flat pressing driving member are all made of servo motors.

[0074] The present invention provides a method for applying glue on the surface of a motor using a glue applying device, comprising:

[0075] Step 1: The motor is fixed on the carrier assembly;

[0076] Step 2: The first glue pressing assembly moves to press the conductive glue onto the surface of the motor stator and press it down near the end cover;

[0077] Step 3: The second glue pressing assembly moves to press the conductive glue pressed down near the end cover into the groove of the end cover;

[0078] Step 4: The carrier assembly moves the motor to the third glue pressing assembly position;

[0079] Step 5: The third glue pressing assembly moves to press the conductive glue onto the end cover surface, the end cover groove and the outer circumferential surface of the end cover.

[0080] The movement of the first glue pressing component in step 2 includes

[0081] S1, the downward pressure driving member is started, driving the first floating pressure block group to move downward;

[0082] S2, the first floating pressing cylinder is started to drive the first floating pressing block group to continue to move downward, and after the middle pressing block contacts the surface of the motor stator, the conductive glue is pressed onto the surface of the stator;

[0083] S3, the side pressing block continues to move downward to bend the conductive adhesive 90 degrees, and pull the conductive adhesive near the surface of the motor end cover;

[0084] S4. In step S3, the side pressing block continues to move downward to bend the conductive adhesive, and the middle pressing block moves upward under the action of the spring and presses the conductive adhesive tightly against the surface of the motor stator.

[0085] The movement of the second glue pressing component in step 3 includes

[0086] C1. The pressing drive is started, driving the pressing block to move forward horizontally;

[0087] C2, the pressing block passes through the first glue pressing assembly and presses the conductive glue located at the end cover groove into the end cover groove;

[0088] C3. The pressing driving member drives the pressing block to move backward laterally to separate from the first glue pressing assembly.

[0089] The movement of the third glue pressing component in step 5 includes

[0090] D1, the flat pressure driving member starts, driving the second floating pressure block group to move forward horizontally;

[0091] D2. The groove pressing block first contacts the conductive glue in the end cover groove, pressing the conductive glue into the end cover groove;

[0092] D3, the second floating pressing cylinder is started to drive the second floating pressing block group to continue to move horizontally, and the plane pressing block continues to move horizontally and contacts the surface of the motor end cover and the outer cylindrical surface of the end cover, and presses the conductive glue on the surface of the motor end cover and the outer cylindrical surface of the end cover;

[0093] D4. In step D3, while the plane pressing block continues to move laterally to perform end face glue pressing, the groove pressing block moves laterally backward under the action of the spring and presses the conductive glue tightly into the end cover groove.

[0094] Specifically, in this embodiment, the conductive adhesive is not flexible in one go during the stretching and pressing process, and the motor has an uneven surface where the conductive adhesive is attached. If the conductive adhesive is not flexible after being stretched, it may break easily during the pressing process due to the uneven surface.

[0095] Combined with the actual situation on site, the glue sticking method of the present invention is adopted:

[0096] 1. Segmented press-fitting. The conductive adhesive is pressed on the motor in three steps. In the first step, the servo motor drives the first floating pressure block group to press the conductive adhesive to the top of the motor end cover. At this time, the conductive adhesive contacts the surface of the motor stator, while the part corresponding to the motor end cover does not contact any part of the motor and is still in a relaxed and flexible state. In the second step, when the conductive adhesive is in a flexible state, the cylinders on both sides of the end face drive the lateral pressing blocks to press the conductive adhesive arranged vertically horizontally. The press-fitting is mainly for the groove. The conductive adhesive is first pressed into the groove. At this time, the conductive adhesive has not yet contacted any part of the motor and is not pressed tightly in a flexible and shrinkable state. First, ensure that there is conductive adhesive in the groove to avoid the need for the conductive adhesive to shrink when it is pressed into the groove later. However, because the conductive adhesive has been pressed to the outer circle of the motor end cover, it is in a tensioned state and the conductive adhesive itself does not have shrinkage. It is pressed and cracked when pressed in the groove. In the third step, the cylinder drives the second floating pressure block group to move horizontally to press the conductive adhesive, so that the conductive adhesive is pressed on the surface of the end cover, the groove of the end cover, and the outer circle of the end cover. The conductive adhesive is mounted. The whole process is pressed three times to solve the problem that the conductive adhesive is not flexible due to one-time stretching when pressed to the outer cylindrical surface of the end cover, and breaks when pressed tightly at the groove of the end cover.

[0097] 2. Floating pressing. After the conductive glue is pre-pressed, it must be ensured to fit tightly with the motor end face, and it needs to be pressed again. However, due to the unevenness of the motor end face, if it is strictly designed according to the motor's concave-convex structural dimensions, it is difficult to ensure that the glue sticking device can ensure that all parts are pressed according to the motor's concave-convex structural dimensions due to product size tolerances and tooling positioning tolerances. Therefore, the glue sticking device adopts floating pressing, and the conductive glue pressing on the end cover adopts a combination of plane pressing and groove floating pressing. The plane pressing is performed by a plane pressing block, and the floating pressing is performed by a spring and a groove pressing block. Because there are two grooves on the end cover surface, two groove pressing blocks are used respectively, namely the first groove pressing block and the second groove pressing block. When the plane pressing block contacts the motor end face, the first groove pressing block and the second groove pressing block are pressed in first. Because they have floating properties and the groove pressing block contacts the end cover surface first, after the groove is pressed, the plane pressing block is pressed to the end cover surface to ensure that the end cover groove and the motor end face can be pressed synchronously. The conductive adhesive cannot be moved again after the end face is pressed, and the groove is not pressed into place or is directly broken. The floating pressing power is input by cylinder.

The adhesive laminating method according to claim 7, characterized in that: The movement of the third glue pressing component in step 5 includes D1, the flat pressure driving member starts, driving the second floating pressure block group to move forward horizontally; D2. The groove pressing block first contacts the conductive glue in the end cover groove, pressing the conductive glue into the end cover groove; D3, the second floating pressing cylinder is started to drive the second floating pressing block group to continue to move horizontally, and the plane pressing block continues to move horizontally and contacts the surface of the motor end cover and the outer cylindrical surface of the end cover, and presses the conductive glue on the surface of the motor end cover and the outer cylindrical surface of the end cover; D4. In step D3, while the plane pressing block continues to move laterally to perform end face glue pressing, the groove pressing block moves laterally backward under the action of the spring and presses the conductive glue tightly into the end cover groove.
