The assembly fixture of claim 1, wherein The length of the magnetic cover plate of the magnetic device in the second direction is less than or equal to the distance between the first pressing plate and the second pressing plate, so that the magnetic cover plate is positioned by being clamped between the first pressing plate and the second pressing plate in the second direction.

5. The assembly fixture of claim 1, wherein The plurality of terminals of the magnetic device are arranged on two material tapes, and the two material tapes are respectively attached to opposite sides of the base wall. The first pressing plate and the second pressing plate are respectively provided with a avoiding area for accommodating the corresponding material tape to allow the material tape not to be subjected to the force from the first pressing plate and the second pressing plate towards the base wall.

6. The assembly fixture of claim 5, wherein, The assembly jig further comprises a lower waste material assembly which is connectable with the material tape to drive the material tape to be separated from the corresponding terminal and the base wall.

7. The assembly jig according to claim 6, wherein the base body is provided with a fixing hole; the lower waste material assembly comprises a carrier plate, a clamping member, a limiting block and an elastic member; one end of the elastic member is fixedly connected with the carrier plate, and the other end of the elastic member is connected with the limiting block; the limiting block is arranged on the carrier plate, and the limiting block is used for driving the clamping member to move back and forth in the fixing hole to drive the distance between the clamping member and the side surface of the carrier plate and shake the material tape clamped between the clamping member and the side surface of the carrier plate.

8. The assembly fixture of claim 7, wherein, The fastening member is located above the carrier plate or abuts against the surface of the carrier plate.

9. The assembly jig according to claim 7, wherein the material tape is attached to the base wall by a plurality of fixing members. The carrier plate is provided with a plurality of clamping holes on one side of the side surface, and each fixing member is accommodated in a corresponding clamping hole and clamped with the clamping hole.
